Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of fitness equipment, and specifically to a swing arm connection structure for fitness equipment.BACKGROUND

[0002] At present, people are increasingly pursuing a healthy life as people's living standards are improved and national fitness is launched. In people's daily lives, fitness is an indispensable part. Also, more and more people take exercises using specialized fitness equipment in a fitness room due to the change in fitness concepts.

[0003] Specialized fitness equipment is used in the fitness room for the body part to be trained or a desired exercise routine, such as a Smith machine, a seated rowing machine, a leg press machine, a counter-balanced smith machine, a T bar pulldown machine, a barbell rack, etc. These pieces of fitness equipment, usually taking up a relatively large footprint, are affordable for a large health club, but not for ordinary families. Further, each of these pieces of fitness equipment usually can fulfill only single-action training due to its dedicated purpose, and even if a piece of fitness equipment can fulfill training having some actions, it is difficult to reduce its footprint.

[0004] Thus, to attract ordinary families, various types of novel intelligent fitness equipment emerge in the market. Generally, these pieces of fitness equipment are configured to use a weight balance mode, such as the electrodynamic force / wind resistance / electromagnetic resistance, that can be digitally controlled instead of traditional physical balance weights such as weight plates, and to have a swing arm freely movable in multiple directions which is designed by combining multiple units in the field of conventional fitness apparatuses, such as pulling handles / pulling ropes / rope fixtures / rope outlet and lock devices, thereby producing a multifunctional machine by a compact structure to fulfill people's conventional training routines. For example, for apparatuses such as the counter-balanced smith machine or gantry frame used during regular fitness, traditional equipment also needs to be equipped with multiple weight plates with a specific weight which are pulled by two hands or one hand to achieve specific training purposes. However, the novel intelligent fitness equipment can use the electrodynamic force / wind resistance / electromagnetic resistance, etc. to replace weight plates, thereby reducing an equipment size, and making it possible to introduce dedicated fitness equipment into ordinary families.

[0005] For example, U.S. Patent US2021038937 (A1) discloses fitness equipment which, for example, can be placed vertically on a horizontal ground, and has a motor as a resistance source, and each of two sides of the equipment are provided with two swing arms which can move up and down in the vertical direction perpendicular to the ground, so that a user can take exercises by using handles at front ends of the swing arms.Patent Document 1

[0006] U.S. Patent US2021038937 (A1)BRIEF SUMMARY Technical Problem to be Solved by the Application

[0007] However, the fitness equipment in Patent Document 1 has an excessive integration level, causing a high cost and enormous manufacture difficulty. Additionally, existing fitness equipment, even if it is integrated with some structures, is still dedicated for users in a professional fitness club, and still has a too large volume, so that it is not suitable for placement in an ordinary family house. Accordingly, for the ordinary family house, the existing fitness equipment also has the problem of a too large footprint. In particular, as described above, the fitness equipment has a swing arm used for exercises taken by exercisers, and the swing arm usually needs to have a certain length to meet the demands during exercises. However, the swing arm of the existing fitness equipment generally has a relatively large length, so, even if the fitness equipment is placed into an ordinary house, it may still take up excessive residence space, and thus is not suitable for being placed in the ordinary house.

[0008] Additionally, when the fitness equipment is used, the swing arm requires additional space for up-and-down and left-and-right swing thereof for various exercise routines. To allow the swing space for the swing arm, the fitness equipment needs to have a relatively high height or be placed at a relatively high position. So, such setting is still not suitable for the ordinary house, and even, the fitness equipment cannot be placed in some small houses, preventing the popularization of the fitness equipment.

[0009] Additionally, the swing arms are usually disposed at both outer sides of the fitness equipment. When the equipment is not used, its outwardly disposed components, such as the swing arms, etc. cannot be hided via storage. So, even if such fitness equipment is barely placed in an ordinary house, it is still not in harmony with the house due to the exposure of the swing arm and other components, which also affects the aesthetic effects of the fitness equipment and even the house in which the fitness equipment is placed. In addition, fitness equipment for use at home is not frequently used as that for use at fitness clubs, and should be disposed in place, so that it would not interfere with life' affairs when it does not need to be used. But the fitness equipment cannot be placed in the ordinary house, and even if it is barely placed, there are also problems of space waste and unaesthetic effects.

[0010] Additionally, the swing arm of the prior-art fitness equipment is too long, thereby leading to a too large torque at a swing arm connection (e.g., a joint), and thus potentially causing damage to the fitness equipment.

[0011] In this regard, the present application aims to provide a swing arm connection structure for fitness equipment and fitness equipment having the same. The fitness equipment is suitable for placement and use in a room of an ordinary family house, can simplify a manufacturing process and reduce a cost, and prevent the problem of a too large torque at a joint due to a too long swing arm. The fitness equipment has a compact structure, and can be received in a very small size when not in use, reducing its footprint occupied in a family house, and also enabling aesthetic appearance.Technical Solution to Problem

[0018] Further, according to some examples, preferably, the guide rail unit is disposed at the side surface of the main part.

[0019] Further, according to some examples, preferably, the main part is isosceles trapezoid-like, and has parallel upper and lower bases, and two side edges of the main part as legs of the isosceles trapezoid, the front panel is rectangular, and has a top edge, a bottom edge and two front panel side edges, the front panel has a height greater than that of the main part, the upper base of the main part is located below the top edge of the front panel, and the lower base of the main part is located above the bottom edge of the front panel, and the two guide rail units are disposed at the side edges of the main part along the side edges of the main part.

[0020] Further, according to some examples, preferably, the front panel is a touchable electronic screen or mirror.

[0021] Further, according to some examples, preferably, the swing arm unit is connected to the slider unit by pivot connection.

[0022] Further, according to some examples, preferably, the rail unit is provided with a plurality of clamping holes, and the slider unit is provided with a clamping pin which can be inserted into and removed from the clamping holes.

[0023] In the fitness equipment of the present application, the swing arm connection structure described above is provided.

[0024] Further, according to some examples, preferably, the fitness equipment comprises a resistance source disposed inside the main part; a wire spool connected to the resistance source and wound with a rope; a handle disposed at the front end of the swing arm unit; and a pulley set guiding the rope to the handle.

[0025] Further, according to some examples, preferably, the pulley set comprises a first fixed pulley disposed inside the main part, a second fixed pulley disposed at the top of the main part, a third fixed pulley disposed at the slider unit, and a fourth fixed pulley disposed at the base end side of the swing arm unit, and a wrist-joint pulley disposed at the front end side of the swing arm unit, and the rope is connected to the handle via the wrist-joint pulley after passing through the first fixed pulley, the second fixed pulley, the third fixed pulley and the fourth fixed pulley and the interior of the swing arm unit from the wire spool.

[0026] Further, according to some examples, preferably, the resistance source is an inner-rotor motor comprising a housing, a motor stator disposed within the housing, and a motor rotor disposed within the motor stator, and further, the wire spool is mounted to the motor rotor.Effect of the Application

[0027] According to the present application, since the sliders can slide along the guide rail, the two sliders are close to each other when they are located at the top of the front panel, and are gradually separated as they slide toward the bottom of the front panel. Thus, when the two sliders are at the top, the two sliders and the swing arm connected thereto can be fully received at the back area of the fitness equipment.

[0028] Therefore, when the swing arm of the fitness equipment is in a receiving state, the swing arm cannot be seen at all when the user of the fitness equipment looks at the front panel since the swing arm, as well as the sliders, is blocked by the front panel and is hidden behind the front panel. Thus, the swing arm connection structure can be fully hidden only by the front panel, so that the fitness equipment can have a more integrated design, which is more aseptic and suitable for use at home.

[0029] Additionally, when the fitness equipment is idle, since at this time the swing arm connection structure does not protrude sideways and is completely hidden, the fitness equipment can have a reduced height, leading to a small packaging size and a low weight thereof, and is easy for transportation and installation. The equipment has a small volume, enabling space saving and more aesthetic appearance. When the swing arm is received, any other components are invisible at all except the front panel, and especially when the front panel is a mirror display, the fitness equipment can be correspondingly used as a mirror or display screen when it is idle and its swing arm is received.

[0030] Additionally, when it needs to use the fitness equipment for exercise, the swing arm can be in an operating position by simply sliding the slider downward to gradually expose it sideways from the receiving area behind the front panel, and thus to expose the swing arm sideways from the receiving area behind the front panel. That enables easy use.

[0031] Additionally, by disposing a plurality of clamping holes in the guide rail and a plurality of clamping pins at the slider, the slider can be positioned at a plurality of locations at the guide rail according to actual use situations, so that the present application can be suitable for strength training with the swing arm at different heights according to various demands, and achieve multiple exercises by only one fitness equipment, and it is easy to use.

[0032] Additionally, for convenience of training activities conducted by users, such as deep squats, deadlift, back to back tug, etc., the rope needs to be positioned at a specified distance from a surrounding wall, so that its end is not jammed when the rope is pulled for respective training routines, especially when, for a low or high position, the protruding end of the rope needs cover a relatively large "protruding end range" for strength training. In this regard, in the present application, since the swing arm can be adjusted for its height position up and down as the slider slides, the fitness equipment can be hung on a wall for use. In this case, since the fitness equipment is hung on the wall at a certain distance from the floor and the position of base end of the swing arm can be adjusted up and down with the slider, the swing arm can more easily fulfill the "protruding end range". Thus, the swing arm can be relatively short, so that the torque at a connection is small.

[0033] In conclusion, according to the present application, the wide coverage range of the tail end of the swing arm can be realized by small-sized fitness equipment, and a too large torque at a joint due to a too long swing arm can also be prevented, thereby enabling a reduced footprint at home and more aesthetic appearance.BRIEF DESCRIPTION OF THE DRAWINGS

[0036] Hereinafter, the present application is described in detail with reference to the figures. It should be understood that various specific embodiments described in the application are only fully described examples and do not limit the scope of protection of the application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without the exercise of inventive effort fall within the scope of protection of the present application.

[0037] For ease of illustration, terms representing orientations are used below, such as "upper", "lower", "left", "right", "horizontal", 'vertical', etc., but they are only limited to the relative positional relation among components in a specific position, for example, shown in the figures. If the specific position changes, the terms to indicate the orientations would of course change accordingly.

[0038] In the application, unless otherwise specified, terms "connection", "articulation", "fixing", etc. are understood in a broad sense. For example, "fixing" can be fixed or removable connection, or one-piece formation; "connection" may be mechanical or electrical connection, or direct or indirect connection via an intermediate medium.

[0039] Additionally, the figures are schematic and do not indicate an actual product structure. For ease of illustration and understanding, components are not necessarily drawn to scale with respect to actual products.The present application is described in detail below.

[0040] Figs. 1-4 illustrate a case where a swing arm unit 4 of fitness equipment F according to the present application is in a receiving state, wherein Fig. 1 is a front view of the fitness equipment F in a receiving state according to the present application, Fig. 2 is a side view of the fitness equipment F in the state shown in Fig. 1 according to the present application, Fig. 3 is a rear view of the fitness equipment F in the state shown in Fig. 1 according to the present application, and Fig. 4 is a rear-view prospective view of the fitness equipment F in the state shown in Fig. 1 according to the present application. Additionally, Figs. 5 and 6 shows a case where the swing arm unit 4 of the fitness equipment F according to the present application is in an open state (an operating state of the fitness equipment F), wherein Fig. 5 is a front view of the swing arm unit 4 in an open state when the slider unit 3 of the fitness equipment F of the present application is located at the lowermost end of the guide rail unit 5 (an operating state of the fitness equipment F, when the slider unit 3 is located at the lowermost end of the guide rail unit 5, the swing arm unit 4 changes from a state where it is vertically placed to a state where it is opened substantially in a horizontal plane), and Fig. 6 is a side view of the fitness equipment F in the state shown in Fig. 5 according to the present application. Figs. 7-9 are schematic views of the process of the fitness equipment according to the present application from a receiving state to a state where the swing arm unit 4 is in an open state, wherein, for ease of illustration, Figs. 7-9 show the positions and states of the slider unit 3, swing arm unit 4, and guide rail unit 5 all by a perspective view, and actually, a user cannot see the slider unit 3 and guide rail unit 5 when facing the front panel 2 of the fitness equipment F (also, Fig. 7 shows the receiving state described below, in which a user cannot see not only the slider unit 3 and the guide rail unit 5, but also the swing arm unit 4 when facing the front panel 2 of the fitness equipment F). Additionally, Fig. 10 is a side view of the fitness equipment F according to the present application in another case where the swing arm unit 4 is in an open state (another operating state of the fitness equipment F, for example, when the slider unit 3 is not located at the lowermost end of the guide rail unit 5, but at a position in the middle of the guide rail unit 5). Fig. 11 is a schematic view of an example of the swing arm connection structure of the fitness equipment F according to the present application, in which other parts are omitted to show only the swing arm connection structure. Additionally, Fig. 31 is an exploded schematic view of the fitness equipment according to the present application.-Overall Structure of Fitness Equipment-

[0041] As shown in Figs. 1-11 and 31, in one embodiment of the present application, the fitness equipment F mainly comprises a main part 1, a front panel 2 disposed at the face side of the main part 1 (the side facing the reader in Fig. 1, and the right side in Fig. 2), a guide rail unit 5 disposed at the back side of the front panel 2 (the opposite side of the face side of the main part 1, and the left side in Fig. 2), a slider unit 3 slidably disposed at the guide rail unit 5, and a swing arm unit 4 connected (e.g., pivotally, or rotatably, etc.) to the slider unit 3.

[0042] Here, in the present application, "the guide rail unit 5 being disposed at the back side of the front panel 2" does not necessarily mean that the guide rail unit 5 must be immediately adjacent to the back side of the front panel 2, but that the guide rail unit 5 is spatially located at the back side of the front panel 2. For example, as shown in Fig. 4, the guide rail unit 5 may be disposed at the back side of the front panel 2 by being adjacent to the back side of the front panel 2. Additionally, the guide rail unit 5 may also be disposed at the side of the main part 1. In this case, when the guide rail unit 5 is disposed at the side of the main part 1, since the front panel 2 is disposed at the face side (front side) of the main part 1, the main part 1 is located at the back side of the front panel 2, and therefore the guide rail unit 5 disposed at the side of the main part 1 is actually necessarily located at the back side of the front panel 2, i.e., it can also be understood here that the guide rail unit 5 is spatially disposed at the back side of the front panel 2 (but not necessarily immediately adjacent to the back side of the front panel 2). Additionally, the guide rail unit 5 may also be disposed at the back side of the main part 1. Here, since the main part 1 is located at the back side of the front panel 2, the guide rail unit 5 located at the back side of the main part 1 is actually necessarily located at the back side of the front panel 2, i.e., it can also be understood here that the guide rail unit 5 is spatially disposed at the back side of the front panel 2 (which is located at the back side of the front panel 2 by being spaced apart from the main part 1).

[0043] Further, in the shown example, the labeled position of the slider unit 3 is merely exemplary, and the slider unit 3 may be located within the housing 45 of the swing arm unit 4 described below. That is, the slider unit 3 may be received and hidden by a part of the housing of the swing arm unit 4, and is invisible. In the present application, both the slider unit 3 and the swing arm unit 4 are composed of a plurality of components, and for ease of understanding, the location labeled in the figures represents the location of the slider unit 3, but does not necessarily mean that the component is the slider unit 3.

[0044] Hereinafter, in the figures of the present application, as shown in Figs. 3, 4, 11 and 31, for ease of illustration, description is made by an example in which the guide rail unit 5 is disposed at the sides (both left and right sides in Fig. 3) of the main part 1. However, the present application is not limited thereto. As described above, the shown guide rail unit 5 which is disposed at the side of the main part 1 is only an example of the guide rail unit 5 which is disposed at the back side of the front panel 2.

[0045] Also, as shown in Figs. 3-11, in one embodiment of the present application, the swing arm 42 (which will be described below) of the swing arm unit 4 is substantially strip-like, for example, bar-like, but the present application is not limited thereto, and it may also be formed as a strip shape with a rectangular cross section or a cross section having another shape, or other shapes.

[0046] Further, in the present application, the swing arm unit 4 is connected to the slider unit 3. Here, for ease of understanding and illustration, the end of the swing arm unit 4 that is connected to the slider unit 3 is called the base end (the end at the upper side of the swing arm unit 4 in Fig. 2), and the other end of the swing arm unit 4 that is opposite to the base end (i.e., the end of the swing arm unit 4 that is not connected to the slider unit 3, and the end at the lower side of the swing arm unit 4 in Fig. 2) is called a front end. In other words, in the present application, the front end and the base end of the swing arm unit 4 refer to two ends of the swing arm unit 4 that are opposite each other in the length direction of the swing arm unit 4.

[0047] Also, as described above, in the present application, a case that two guide rail units 5 are disposed at the side of the main part 1 is mainly shown. Here, preferably, the two guide rail units 5 have the same structure, each of them is provided with a slider unit 3 which can slide thereon, and each slider unit 3 is connected to the swing arm unit 4. In the description, for ease of illustration, only the slider unit 3, swing arm unit 4, and guide rail unit 5 at one of the sides of the main part 1 are illustrated as examples, the illustration of structure of the other side being omitted. Additionally, for ease of understanding, the slider unit 3, swing arm unit 4, and guide rail unit 5 located at one side are sometimes collectively called "a swing arm connection structure". Further, as shown in Fig. 7, in a preferred embodiment of the present application, when the user faces the fitness equipment F, preferably, the front panel 2 of the fitness equipment F is centrally symmetrical with the center line L as the line of symmetry, and the two swing arm connection structures described above are disposed symmetrically with respect to the center line L at both left and right sides of the fitness equipment F.

[0048] Further, for ease of illustration, in the present application, taking the fitness equipment F in the states shown in Figs. 1-4 as an example, the side of the fitness equipment F (the front panel 2) towards the user is called "a face side or a front side" (the side towards the reader in Fig. 1, and the right side in Fig. 2), and the side opposite to "the face side" is called "a back side or an opposite side" (the side opposite to the side where the front panel 2 is in Fig. 2, i.e., the left side in Fig. 2). Additionally, the left-hand side when the user faces the fitness equipment F is called "a left side" (the left side in the front view of Fig. 1, and the right side in the rear view of Fig. 3), and the right-hand side when the user faces the fitness equipment F is called "a right side" (the right side in the front view of Fig. 1, and the left side in the rear view of Fig. 3). Additionally, in the state shown in Fig. 1, an up-down direction is sometimes called "the height direction of the fitness equipment", and a left-right direction is called "the width direction of the fitness equipment". In the state shown in Fig. 2, the left-right direction is sometimes called "the thickness direction of the fitness equipment", "the depth direction of the fitness equipment", or "the front-back direction of the fitness equipment". In the present application, the description about the directions and orientations is made only to facilitate the illustration of the relative positional relations of the components of the fitness equipment according to the present application. If the position and orientation of the fitness equipment F change, the terms indicating orientations would change accordingly.

[0049] Additionally, as shown in Figs. 31-34, a power source (in the present application, for example, description is made by taking a motor 6 as an example) as a resistance source, a wire spool 7 wound with a rope R, a resistance transmission mechanism, which can transmit the resistance generated by the motor 6 as a resistance source to the wire spool 7, or the like are also usually disposed inside the main part 1. As shown in the figures, the rope R onto the wire spool 7 protrudes out of the swing arm unit 4, from the interior of the main part 1, by being directed by for example a pulley or a pulley set, and passing through the interior of the swing arm unit 4, and is connected to an exercise unit, e.g., a handle or a knob held by the user, located at the front end of the swing arm unit 4. In one example, the wire spool 7 is mounted to the motor 6, the wire spool 7 rotates as the motor 6 rotates, a winding force can be applied to the rope R to wind it onto the wire spool 7 when the motor 6 rotates in the direction in which the rope R can be wound, and further, when the rope R is pulled by an external force, a pulling force is applied to the rope R to unwind the wire spool 7. Thus the user of the fitness equipment F can hold, for example, the handle and pull the rope, and feel the resistance generated by the motor 6 as a resistance source, thereby realizing various strength training and regular exercises. Of course, the motor 6 can also rotate in the direction opposite to the rotation direction as described above, and at this time, if the rope R is not subjected to other external forces, the rope R is loosely wound onto the wire spool 7.

[0050] Here, as a specific example of transmitting the resistance generated by the motor 6 as a resistance source by the rope R, for example, as shown in Fig. 32, the wire spool 7 is mounted to the motor 6, the rope R wound onto the wire spool 7, after passing through the first fixed pulley d1 inside the main part 1, is directed upward along the side edge of the main part 1, then directed downward along the length direction of the guide rail unit 5 by the second fixed pulley d2 located at the top of the main part 1, and then enters the swing arm unit 4 by the third fixed pulley d3 of the slider unit 3 and the fourth fixed pulley d4 of the swing arm unit 4, wherein the rope R between the third fixed pulley d3 and the fourth fixed pulley d4 is coaxial with the rotational axis of the swing arm unit 4 (the rotational axis of the swing arm unit 4 when it rotates around the slider unit 3 up and down with the slider unit 3 as the center in Fig. 10) to ensure that the rope R is always coplanar and tangential to the third fixed pulley d3 and the fourth fixed pulley d4 when the swing arm unit 4 rotates. Additionally, the rope R between the second fixed pulley d2 and the third fixed pulley d3 is parallel to the guide rail 52 of the guide rail unit 5 to ensure that the rope R is always coplanar and tangential to the second fixed pulley d2 and the third fixed pulley d3 when the slider unit 3 moves on the guide rail unit 5. Next, as shown in Fig. 32, after the rope R enters the swing arm unit 4 after passing through the fourth fixed pulley d4 of the swing arm unit 4, the rope R further protrudes out of the swing arm unit 4 through the wrist-joint pulleys d5 at the front end portion of the swing arm until 4 (two wrist-joint pulleys d5 which sandwich the rope R are shown in the figure), the end of the rope R after protruding out of the swing arm unit 4 serves as the protruding end (described below), and the front end of the swing arm unit 4 can be connected to other unit components, such as a handle or a knob, or other units as needed. Thus, when the motor 6 operates in a rotation direction in which the rope R can be wound, the rope R is loaded by a winding force to wind it onto the wire spool 7, and when the user pulls the rope R, for example, by holding the handle, an external force is applied to the rope R to unwind it from the wire spool 7. In this case, the resistance applied by the motor 6 is opposite to the external force with which the user pulls the rope R, and is transmitted via each pulley, thereby achieving strength training. The above is only a preferred example of resistance transmission, the present application is not limited thereto, and other pulleys or pulley blocks or other modes may be used to transmit the resistance. Further, in the above description, the resistance transmission at only one side in Fig. 32 is illustrated as an example, and the description for the other side is omitted.

[0051] Additionally, the resistance transmission mechanism is not particularly limited, and may be a planetary differential gear, a bevel gear set, or any other mechanism which can transmit resistance, as long as it can transmit the resistance generated by the motor 6 as a resistance source to the wire spool 7. Additionally, as shown in Fig. 34 (described hereinafter), the wire spool 7 is directly mounted to the motor 6 as a resistance source without a resistance transmission mechanism, and there is no limitation on such modes.-Motor as a Resistance source or Power Source-

[0052] In the present application, for example, the inner-rotor motor M shown in Figs. 33 and 34 may be used as the motor 6 as a resistance source or power source. Specifically, as shown in Figs. 33 and 34, the inner-rotor motor M mainly comprises: a housing M1, a motor stator M2, and a motor rotor M3, wherein the motor rotor M3 is disposed within the motor stator M2, and the motor rotor M3 has a rotor shaft M4 as a center shaft. Additionally, the wire spool 7 described above is mounted on the motor rotor M3. The housing M1 can contain the motor stator M2, the motor rotor M3, and the wire spool 7 therein.

[0053] Specifically, as shown in Fig. 34, the wire spool 7 is fixed in the axial direction of the rotor shaft M4 by being laminated onto the motor rotor M3 in a coaxial manner with the motor rotor M3, and the housing H receives therein the motor stator M2, the motor rotor M3 disposed within the motor stator M2, and the wire spool 7 coaxially laminated onto and fixed to the motor rotor M3. That is, the motor rotor M3, rotor shaft M4, and wire spool 7 are fixed together to form a one-piece structure, can rotate about a center axis, and are received in the housing M1 along with the motor stator M2.

[0054] Additionally, the housing M1 is formed by an upper end cap M5 and a lower end cap M6. Specifically, the upper end cap M5 and lower end cap M6 are substantially cup-shaped (concave), and combined by snap fit to form the housing M1, so as to form a receiving space therebetween. Components, such as the motor stator M2, motor rotor M3, rotor shaft M4, wire spool 7, etc. are received in the receiving space.

[0055] Additionally, the rotor shaft M4 as the center shaft has both ends, one of which is fixed to one of the upper end cap M5 and the lower end cap M6 by bearings respectively, and one of the ends is also connected to an external resistance source or the like so as to function as a resistance input shaft.

[0056] Additionally, the above-described rope R is wound onto the wire spool 7, and a pull-out opening (not shown) for the rope R is disposed in the housing M1, so that the rope R can be pulled out from the housing M1 to operate the resistance mechanism for exercises or the like. Regarding the mode of winding the rope R onto the wire spool 7, for example, the wire spool 7 may be formed in a cylinder shape, and the rope R is directly wound around its periphery. In addition, the wire spool 7 may be formed as a flange to prevent the rope R wound onto the wire spool 7 from falling off.

[0057] Further, the inner-rotor motor M described above is only an example of the motor 6 as a resistance or power source in the present application, and the application is not limited thereto, and may use other motors. For example, it is possible to use an external-rotor motor, a motor provided with a planetary wheel transmission group, a motor provided with a bevel gear group, a motor provided with some other resistance transmission mechanisms, or the like. In view of miniaturization of the fitness equipment F, preferably, as shown in Figs. 33 and 34, the inner-rotor motor is employed, and the wire spool is mounted directly on the motor and received in the housing.

[0058] Additionally, since the present application mainly relates to the swing arm connection structure for fitness equipment, description of structures, such as the motor 6 as a resistance source, the wire spool 7, and the rope R, is sometimes omitted in the following description and figures, and only the content about the swing arm connection structure is described in detail.

[0059] Additionally, in the following, description is made by an example in which the front panel 2 of the fitness equipment F is placed vertically, one swing arm connection structure (the slider unit 3, swing arm unit 4, and guide rail unit 5) is disposed at each of both left and right sides of the fitness equipment F, and both the swing arm connection structures are in central symmetry with respect to the center line L.-Front Panel-

[0060] In the present application, in view of the cost of materials, the front panel 2 may be a conventional sheet material, such as a conventional plastic sheet or a high-hardness plastic, or the like, but may also be a display panel and an operation panel (e.g., a liquid crystal display, a touch panel, or the like), or a structure in which a display screen and an operation screen are disposed on a sheet material. By such a design, it is convenient for the user of the fitness equipment F to switch desired exercise items, read and input fitness data, and know about exercise situations in real time by the front panel 2, and the front panel 2 may also display fitness course videos, or play entertainment programs and the like. In addition to the above functions, the front panel 2 can also be made into a mirror or mirror display equipment having display operation functions, so that the user of the fitness equipment can observe its exercise movement and perform operations at any time. Additionally, as shown in Figs. 1-11 and Fig. 31, when the swing arm unit 4 is in the receiving state, if the front panel 2 is made in the form of a mirror or a mirror display, the entire fitness equipment F is mirror-like in appearance because the swing arm unit 4 is invisible (described below), and can be used as a mirror or display equipment. The fitness equipment can be temporarily utilized as a mirror such as a dress mirror, even it is power off. Thus, when the equipment is placed in an ordinary house, it will be in harmony with usual household equipment, without destroying the overall aesthetics of the house.

[0061] Additionally, in the present application, as shown in Figs. 1-11 and Fig. 31, the swing arm unit 4 of the fitness equipment F being in a receiving state means that, as shown in the front view in Fig. 1 and the exploded view in Fig. 31, the length and width sizes of the face side of the front panel 2 are larger than that of the face side of the main part 1 (the plan view size of the front panel 2 can substantially cover that of the main part 1), so that, when the user of the fitness equipment F faces the equipment in front of the front panel 2, the user cannot see the swing arm unit 4 since it is blocked by the front panel 2. That is, the receiving state is a state where the swing arm unit 4 is hidden at the back side of the front panel 2. Additionally, the swing arm unit 4 of the fitness equipment F being in an operating state means, as described below, a state in which the slider unit 3 slides along the guide rail unit 5 to enable an exerciser to take exercise by the swing arm unit 4, for example, the state shown in Fig. 5 in which the slider unit 3 and the base ends of the swing arm unit 4 are located at the lower end of the guide rail unit 5 (the bottom of the fitness equipment F), or the state shown in Fig. 10 in which the slider unit 3 and the base ends of the swing arm unit 4 are located at the middle portion of the guide rail unit 5. That is, the operating state refers to a state where the swing arm unit 4 is exposed from the side of the fitness equipment F to enable users to use the fitness equipment F by performing operations via the swing arm unit 4.-First Embodiment-

[0062] A specific embodiment of the swing arm connection structure of the present application is specifically described below. Referring to Figs. 1-11, in the present application, the guide rail units 5 are disposed at both left and right sides of the main part 1, and linearly extend in an up-and-down direction, and there is an angle between the guide rail units 5 at the left and right sides. In other words, the guide rail units 5 located at the left and right sides of the main part 1 are not parallel, linearly extend and intersect in the extension direction.

[0063] Here, the so-called "up-and-down direction" is not defined as a geometrically vertical up-and-down direction (a plumb-line up-and-down direction), but also includes, for example, a case in which the direction is slightly inclined at an angle relative to the vertical direction. Additionally, as described above, "disposing the guide rail units 5 at both left and right sides of the main part 1" is not limited to disposing the guide rail units 5 immediately adjacent to both side edges of the main part 1, as long as the guide rail units 5 are spatially located at both left and right sides of the main part 1. For example, as required, the guide rail units 5 may be disposed at both sides of the main part 1, but are separated from the left and right side edges of the main part 1 by a certain spacing, or the guide rail units 5 may be disposed at the left and right sides of the back side of the main part 1 in the thickness direction of the fitness equipment F (e.g., the front panel 2, the main part 1, and the guide rail units 5 are disposed sequentially from the face side to the back side in the thickness direction of the fitness equipment F). That is, in the application, the specific disposing positions of the guide rail units 5 are not limited, as long as the guide rail units 5 at both sides form an angle therebetween. Additionally, since the slider unit 3 slides on the guide rail unit 5, the extension direction of the guide rail unit 5 actually is the sliding direction of the slider unit 3 on the guide rail unit 5.

[0064] Specifically, in a specific embodiment of the present application, the main part 1 is substantially isosceles trapezoid-like (e.g., referring to the rear view of Fig. 3 or the exploded view of Fig. 31), and the guide rail units 5 are disposed at both sides of the main part 1 along both side edges of the main part 1 (e.g., the left and right side edges of the main part 1 in Fig. 3 as the legs of the isosceles trapezoid). Therefore, in this specific embodiment, the extension direction of the guide rail unit 5 actually is the extension direction substantially along the side edges of the legs of the isosceles trapezoid-like main part 1. Here, since the two side edges of the main part 1 are used as the legs of the isosceles trapezoid, the two side edges form an angle relative to each other. Thus, the guide rail units 5 disposed at both left and right side edges of the main part 1 also have an angle therebetween. In other words, the guide rail units 5 disposed at both sides of the main part 1 are not parallel and have the tendency to intersect in the extension direction.

[0065] Additionally, merely to describe the arrangement of the guide rail units 5 herein, description is made by the case, as an example, in which the main part 1 is substantially isosceles trapezoid-like and the guide rail units 5 are disposed at both side edges of the main part 1, but the present application is not limited thereto. The main part 1 may be of an arbitrary shape, e.g., when the guide rail units 5 are disposed at the side edges of the main part 1, the main part 1 may be triangular or of other shapes, as long as the main part has two side edges that are not parallel (intersect) in the extension direction. Further, in the present application, preferably, the two side edges of the main part 1 are centrally symmetrical (e.g., like two legs of an isosceles trapezoid) with respect to the center line L, and so, the specific shape of the main part is not specifically limited. For the stability and receiving of the fitness equipment, preferably, the main part 1 is substantially isosceles trapezoid-like, as shown in Fig. 31.

[0066] Also, it is not necessary to dispose the rail units 5 along both side edges of the main part 1, as long as the two guide rail units 5 are not parallel in the extension direction. Further, as described above, "disposing the guide rail units 5 at both sides of the main part 1" only requires that the guide rail units 5 are spatially located at both sides of the main part 1. For example, the guide rail units 5 can also be disposed at both sides of the back side of the main part 1 (the main part 1 and guide rail units 5 are disposed sequentially along the thickness direction of the fitness equipment F, so that the guide rail units 5 are disposed at the back side of the main part 1 and are located on both sides), without limitation on such disposing. However, for reducing a device thickness to make a thin device, and in view of the sliding stability and safety of the slider unit 3 on the guide rail units 5, preferably, the guide rail units 5 are disposed at the side edges of the main part 1 by being immediately adjacent to the main part 1 in the width direction.-Second Embodiment-

[0067] Another specific embodiment of the swing arm connection structure according to the present application is specifically described below. In another embodiment, the front panel 2 is substantially rectangular, and for ease of illustration, as shown in Figs. 1, 3, and 9, the four edges of the rectangular front panel 2 in the specific embodiment are designated as a first side edge 21 (the side edge on the left of the front view of Fig. 1, and the side edge on the right of the rear view of Fig. 3), a second side edge 22 (the side edge on the right of the front view of Fig. 1, and the side edge on the left of the rear view of Fig. 3), a top edge 23, and a bottom edge 24. The two guide rail units 5 are located at the back side of the front panel 2, and, like the above-described first embodiment, extend linearly and intersect in the extension directions. That is, the two guide rail units 5 at both left and right sides have an angle therebetween.

[0068] As shown in the figures, without regard to the specific shape of the main part 1, the guide rail units 5 at both left and right sides having an angle therebetween means, for example, that each of the guide rail units 5 disposed at both left and right sides of the main part 1 has a specified angle with respect to the side edge of the front panel 2 at the side where each of the guide rail units is located (the first side edge 21 and the second side edge 22 of the front panel 2 in Figs. 1, 3, and 9).

[0069] Specifically, the front panel 2 is substantially rectangular, as shown in the perspective view of Fig. 9 described below, the guide rail unit 5 at the left side is not parallel to the left side edge (the first side edge 21) of the front panel 2, and has a specified angle with respect to the left side edge (the first side edge 21) of the front panel 2, and the guide rail unit 5 at the right side is not parallel to the right side edge (the second side edge 22) of the front panel 2, and has a specified angle with respect to the right side edge (the second side edge 22) of the front panel 2. In other words, the guide rail units 5 at left and right sides are not parallel, and gradually close to each other (the tendency to come close) as they go towards the top end of the front panel 2 (the top edge 23). Thus, as shown in the rear view of Fig. 3 and the perspective view of Fig. 9, the extension directions of the two guide rail units 5 are not parallel, and have the tendency to intersect (meeting in the extension directions) as they go towards the top of the main part 1, and the two guide rail units 5 have an angel therebetween. Here, in the rear view of Fig. 3 and the perspective views of Figs. 7-9, the area enclosed by the two guide rail units 5, and the top edge 23 and bottom edge 24 of the main part 1 is substantially isosceles trapezoid-like, and the width of the legs of isosceles trapezoid is gradually reduced upwards (the extension directions of the two guide rail units 5 have the tendency to intersect as they go towards the top of the main part 1). Here, the so-called "intersecting" or "meeting" means that the two guide rail units 5 have the tendency to intersect (e.g., the extension lines of the rail units intersect in the extension direction), and does not specifically mean that there is an actual intersection point.

[0070] Thus, as shown in Fig. 3 and Figs. 7-9, in a plan view, at the back side of the fitness equipment F, the first side edge 21 (a left side edge) and top edge 23 of the front panel 2, and the guide rail unit 5 at the left side form a first receiving area A, and the second side edge 22 (right side edge), and the top edge 23 of the front panel 2, and the guide rail unit 5 at the right side form a second receiving area B. As can be seen from the figures, the extension directions of the two guide rail units 5 have the tendency to intersect as they go towards the top of the main part 1, and so, at the back side of the front panel 2, the closer the first receiving area A and second receiving area B are to the top edge 23 (the upper portion of the fitness equipment F) of the front panel 2, the larger the planar area of the receiving area thereof is.

[0071] Here, as shown in Figs. 3 and 9, since the slider unit 3 can slide along the guide rail units 5, and the extension directions of the left guide rail unit 5 and the right guide rail unit 5 have the tendency to intersect as they go upward, the two slider units 3 approach when they slide along the guide rail unit 5 to a position close to the top edge 23 of the front panel 2, and thus, at this point, the swing arm units 4 provided at the slider units 3 approach. Thus, when the two slider units 3 slide to a position close to the top edge 23 of the front panel 2, since, at this point, the first receiving area A and the second receiving area B have a large receiving area, the two slider units 3 can be completely received at the back area of the fitness equipment F, and the swing arm units 4 connected to the slider units 3 can also be accordingly received in the corresponding receiving area.

[0072] That is, when the two slider units 3 slide to a position close to the top edge 23 of the front panel 2 (a receiving state), the slider units 3 and the swing arm units 4 can be shielded by the front panel 2 when viewed from the front side of the fitness equipment F (the front panel 2). Thus, the user cannot see the slider unit 3 and swing arm unit 4 received in the first receiving area A and second receiving area B when facing the front panel 2, because the slider unit 3 and the swing arm unit 4 can be hidden at the back side of the front panel 2.

[0073] Therefore, when the slider unit 3 and the swing arm unit 4 of the fitness equipment F are in the receiving state, the swing arm unit 4 and the slider unit 3 are blocked by the front panel 2 if the user of the fitness equipment F looks at the fitness equipment F in front of the front panel 2, and thus the swing arm unit 4 is invisible at all, thereby realizing that the swing arm unit 4 is hidden at the back side of the front panel 2.

[0074] Thus, in the present application, only by cleverly utilizing the guide rail units 5 and front panel 2 without providing dedicated components, the swing arm unit 4 and the slider unit 3 can be completely received in the receiving state at the back side of the fitness equipment F (the front panel 2) in the receiving area, so that the swing arm connection structure can be completely hidden in the receiving state. By this way, the fitness equipment F can have a more integrated design, and when it is idle in the receiving state, the fitness equipment F is more aesthetically pleasing, and is suitable to be placed in an ordinary house in harmony with other furniture. In particular, when the fitness equipment F is idle, it is neat and of a small size since the swing arm connection structure does not protrude sideways and is hidden behind the front panel 2, thus making more aesthetical appearance, and from the face side of the fitness equipment F, components except the front panel 2 cannot be seen at all in the receiving state. Especially, when the front panel 2 is a mirror display, the fitness equipment F in the receiving state can be used as an entertainment display device when power on, and even as an ordinary mirror (e.g., a dress mirror) when power off. Thus, the fitness equipment is of small size, and has neat and aesthetic appearance; it can be easily placed for use in any position in a house, being in harmony with furniture or other articles in a family house; the fitness equipment has no limitation on the place where it is placed, and can save space; and it can be utilized for other purposes even when it is idle, and does not destroy the layout or integrity of a room due to placement of the fitness equipment F at home.

[0075] Additionally, as shown in Fig. 9, the left guide rail unit 5 and the right guide rail unit 5 are gradually separated as the distance therebetween is increased as they go toward the bottom edge 24 (the bottom of the fitness equipment F) of the front panel 2. Therefore, when it is intended to use the fitness equipment F, as shown in Figs. 7-9, just by sliding the slider units 3 downward in the direction shown by the arrow to slide them downward along the guide rail units 5, the slider units 3 will move from the area with a large area in the receiving area at the back side of the front panel 2 to the area with a small area as the two guide rail units 5 are gradually separated (in Figs. 7-9, the upper portions of the receiving area A and receiving area B are the areas with a large area, and the lower the area is, the smaller the area is), and is gradually exposed from the side of the fitness equipment F, and the swing arm unit 4 connected thereto also is gradually exposed sideways from the receiving area at the back side of the front panel 2, thereby enabling an operating state of the swing arm unit 4.

[0076] As an example, Figs. 7-9 show a case in which the slider unit 3 slides along the guide rail units 5 to the lowermost end thereof (the lowermost end of the fitness equipment F). Here, for example, training activities such as deep squats and deadlift can be suitable. Further, as shown in Fig. 10, the slider unit 3 may also slide to the middle of the guide rail unit 5 and fixed for other types of exercise routines, for example, training activities such as back to back tug, and triceps pulldown. Here, the slider unit 3 can be fixed by providing a plurality of clamping holes in the guide rail unit 5 and providing components such as clamping pins that can be clamped in the clamping holes, so that the slider unit 3 can be positioned at a plurality of locations at the guide rail unit 5 according to actual use and exercise routines. That is, the present application can be suitable for strength training with the swing arm at different heights according to various demands, and achieve multiple exercises by only one fitness equipment, and it is easy to use.- Mode of Connecting Swing Arm Unit with Slider Unit-

[0077] In the present application, the mode for connecting the swing arm unit 4 with the slider unit 3 is not limited. For example, a pivot connection structure or other connection modes may be used, preferably, a mode in which the swing arm unit 4 has the tendency to rotate relative to the slider unit 3 in a horizontal plane. Also, the swing arm unit 4 can be rotatably connected to the slider unit 3 in a horizontal plane in view of the functional requirements of the fitness equipment. Further, the swing arm unit 4 can also fixedly connected to the slider unit 3.

[0078] Referring to Figs. 12 and 13, a specific example of connecting the swing arm unit 4 to the slider unit 3 is briefly described. Fig. 12 is an exploded view of an example in which the swing arm unit 4 in the swing arm connection structure of the fitness equipment of the present application is connected to the slider unit 3, and Fig. 13 is a schematic view of an example of the internal structure of the swing arm connection structure of the fitness equipment according to the present application, wherein Fig. 13 is a schematic view when viewed form the top in the state shown in Fig. 1.

[0079] As shown in Figs. 12 and 13, in one embodiment of the present application, the slider unit 3 comprises a slider 31 and a slider fixing seat 32 on which the slider 31 is fixed. The swing arm unit 4 comprises a swing arm fixing seat 41, a swing arm 42 disposed on the swing arm fixing seat 41, and a plain shaft 43. The guide rail unit 5 comprises a bearing seat 51 and a guide rail 52 disposed on the bearing seat 51. Further, the slider 31 of the slider unit 3 can slide along the guide rail 52 of the guide rail unit 5, so that the slider unit 3 including the slider 31 and slider fixing seat 32 fixed thereto can slide along the guide rail 52 of the guide rail unit 5.

[0080] Additionally, as shown in Fig. 13, the swing arm fixing seat 41 is connected to the slider fixing seat 32 via the plain shaft 43 which, at this point, has an effect similar to a pivot shaft, and overall, the swing arm unit 4 and the slider unit 3 are pivotally connected (hinged), so that the swing arm fixing seat 41 and the slider fixing seat 32 have the tendency to pivot relative to each other. However, here, the pivotal connection of the swing arm fixing seat 41 with the slider fixing seat 32 via the plain shaft 43 does not necessarily enable rotation of both of the swing arm fixing seat 41 and the slider fixing seat 32, and it is only required that they have the tendency to rotate (as described below), but they may pivot. Additionally, as a specific mode for pivotally connecting the swing arm unit 4 with the slider unit 3, for example, as shown in Figs. 12, 13, 16, 19, etc., a mode may be used in which the slider fixing seat 32 and the swing arm fixing seat 41 are provided with shaft sleeves (or fixing hoops 47), the plain shaft 43 is inserted into the shaft sleeves (or fixing the fixing hoops), and thus, the swing arm fixing seat 41 and the slider fixing seat 32 are connected via the combination of the plain shaft 43 and shaft sleeves (or the fixing hoops 47). In addition, the swing arm fixing seat 41 and the slider fixing seat 32 can be connected by providing bearings at the swing arm fixing seat 41 and / or the slider fixing seat 32 to install and fix the plain shaft 43. And such connection is not specifically limited.

[0081] Further, in the embodiment shown in Fig. 19, the plain shaft 43 is, but not limited to, a separate component independent of the slider fixing seat 32 and the swing arm fixing seat 41. Also, it is possible to employ a mode in which the plain shaft 43 is fixed to one of the slider fixing seat 32 and swing arm fixing seat 41, the other one is provided with a shaft sleeve or a bearing, and the slider fixing seat 32 and swing arm fixing seat 41 are fixed by inserting the plain shaft 43 in the shaft sleeve or bearing (Fig. 12 or Fig. 16). This is not specifically limited, as long as the slide fixing seat 32 can be pivotally connected with the swing arm fixing seat 41.

[0082] In the present application, preferably, the slider fixing seat 32 and the swing arm fixing seat 41 are provided with shaft sleeves / bearings / fixing hoops corresponding to both ends of the plain shaft 43, and the plain shaft is inserted into respective shaft sleeves / bearings / fixing hoops to connect the slider fixing seat 32 with the swing arm fixing seat 41. Additionally, more preferably, the plain shaft 43 is fixed to the swing arm fixing seat 41 (e.g., referring to Fig. 12 or 16, the plain shaft 43 is integrated with the swing arm fixing seat 41), bearings or shaft sleeves or fixing hoops for both ends of the plain shaft 43 are provided at the slider fixing seat 32, and the plain shaft 43 is inserted into the bearings or shaft sleeves or fixing hoops to realize the mode in which the slider fixing seat 32 and the swing arm fixing seat 41 are pivotally connected.

[0083] Additionally, the guide rail unit 5 as a whole is mounted to the side of the main part 1 by fixing the bearing seat 51 of the guide rail unit 5 to the side of the main part 1. Additionally, a guide rail 52 is fixed on the bearing seat 51 of the guide rail unit 5, so that the slider unit 3 as a whole slides along the guide rail 52 by sliding the slider 31 of the slider unit 3 along the guide rail 52 of the guide rail unit 5, and the swing arm unit 4 connected to the slider unit 3 also slides along the guide rail 52, thus realizing movement of the swing arm unit 4 and the slider unit 3 along the guide rail 52 in a substantially up-and-down direction. By sliding the swing arm unit 4 along the guide rail unit 5 (the guide rail 52) in the substantially up-and-down direction, the position of the slider unit 3 in the height direction and thus the height of the swing arm unit 4 can be adjusted according to exercise routines and for different users.-Position Fixing of Slider Unit relative to Guide Rail Unit and Release of the Fixing-

[0084] In the present application, components such as a pin (a clamping pin) and a pin hole (a clamping hole) are provided, and when the slider unit 3 needs to be fixed with respect to the guide rail unit 5, the slider unit 3 is fixed at a specified position at the guide rail 52 of the guide rail unit 5 by utilizing the insertion combination between the pin and the pin hole, so as to fix (lock) the slider unit 3 to the guide rail unit 5. Additionally, when it is necessary to release the fixation of the slider unit 3 to the guide rail unit 5 to slide the slider unit 3, the positioning of the slider unit 3 and the guide rail unit 5 is changed by separating the pin from the pin hole, thereby releasing the locking between the slider unit 3 and the guide rail unit 5, so that the slider unit 3 can slide along the guide rail unit 5 to drive the swing arm unit 4 thereon to move. The structure thereof is described in detail below.(Mode I)

[0085] As shown in Figs. 12-15, in the guide rail unit 5, a plurality of pin holes (clamping holes) 54 are disposed in the bearing seat 51 along the length direction of the guide rail 52. Here, the plurality of pin holes 54 may be spaced apart at equal intervals, or may be disposed at specific positions at the bearing seat 51 according to a specific exercise routine and a desired height of the slider unit 3. Further, in the figures, description is made by an example in which the pin holes 54 are disposed in the bearing seat 51. But, regarding the disposing position of the pin holes 54, they may be not provided in the bearing seat 51, but directly in the guide rail 52. Here, in view of the force applied to the guide rail and the protection of the guide rail, preferably, the pin holes 54 are not directly disposed in the guide rail 52, but in the bearing seat 51.

[0086] Additionally, as shown in Figs. 12-14, a height position sensor 55 may also be disposed along the length direction of the guide rail 52, to detect the height position of the slider unit 3 (or the slider 31). In the present application, the height position sensor 55 is not limited, for example, a light-sensitive or pressure-sensitive sensor may be used, as long as it can detect the height position of the slider unit 3 (or the slider 31). Also, preferably, the height position sensor 55 is disposed at the side opposite to the guide rail 52 by being immediately adjacent to the bearing seat 51, so as to accurately detect the height position of the slider 31. Additionally, since the base end portion of the swing arm unit 4 connected to the slider unit 3 is always located at the same height position as the slider unit 3, the height position of the slider unit 3 (the slider 31) can also be obtained by detecting the base end portion of the swing arm unit 4, and there is no limitation on such detection.

[0087] Additionally, as shown in Figs. 12-15, corresponding to the above-mentioned pin holes 54, a pin (a clamping pin) 343 that can be inserted into the pin holes 54 is disposed inside the slider unit 3. Thus, the position locking of the slider unit 3 relative to the guide rail unit 5 is realized by inserting the pin 343 into the pin holes 54 disposed at different positions of the guide rail unit 5, and thus the position locking of the base end portion of the swing arm unit 4 is realized. Additionally, when a desired position, especially a height position is adjusted by a user as desired, only by pulling out the pin 343 from the pin hole 54, the fixation (locking) of the slider unit 3 relative to the guide rail unit 5 can be released, and the slider unit 3 can again slide on the guide rail unit 5; and at this point, the fixation of the slider unit 3 with respect to the guide rail unit 5 can be achieved only by the user by, for example, pushing the slider unit 3 to slide it to a desired height position, and reinserting the pin 343 into the pin hole 54.

[0088] Here, as a specific example for a pluggable combination of the pin 343 and the pin hole 54, for example, as shown in Figs. 12-15, a height adjusting part 34, which can insert the pin 343 into the pin hole 54 and pull the pin 343 out of the pin hole 54, is provided in the slider unit 3.

[0089] As shown in Figs. 14 and 15, the height adjusting part 34 mainly comprises: a connecting rod 342 which is substantially elongated rod-like; an adjusting handle 341 fixedly mounted at an upper end portion (the upper portion in the up-and-down direction in Fig. 15) of the connecting rod 342; a pin mounting portion 346 disposed at the middle of the connecting rod 342; a fixed portion 344 disposed at a lower end portion of the connecting rod 342; and the pin 343 (a clamping pin), which is provided at the pin mounting portion 346 and can be inserted into and removed from the pin hole 54 provided in the bearing seat 51 of the guide rail unit 5.

[0090] In this embodiment, as shown in Figs. 12-15, the connecting rod 342, which is substantially linear, is disposed in an up-and-down direction, and the adjusting handle 341 is fixedly disposed at an upper end portion of the connecting rod 342, and the upper end portion can be exposed from the top along with the adjusting handle 341, for example, as shown in Figs. 12 and 13, and the adjusting handle 341 can be exposed from an opening 46 provided in the housing 45 of the swing arm unit 4. Additionally, the pin mounting portion 346 is disposed at the middle portion of the connecting rod 342, and the pin 343 can be mounted at the pin mounting portion 346. For the mode of mounting the pin 343 at the pin mounting portion 346, for example, as shown in Figs. 12-15 and Fig. 17 below, the pin 343 can be mounted at the pin mounting portion 346 by insertion-shaft fixation modes in such a way that the pin 343 is substantially perpendicular with respect to the length direction of the connecting rod 342 (the up-and-down direction in Fig. 15). Here, as shown in Figs. 12-15, when the height adjusting part 34 is mounted on the fitness equipment F, the guide rail unit 5 (the guide rail 52) and the connecting rod 342 as a whole extend substantially in a linear manner in the up-and-down direction, and the pin 343 is substantially perpendicular with respect to the length direction of the connecting rod 342, so the pin 343 is also substantially perpendicular with respect to the guide rail 52 (the guide rail unit 5), and the direction in which the pin 343 is inserted into the pin hole 54 is also substantially perpendicular with respect to the guide rail 52 (the guide rail unit 5).

[0091] Additionally, the fixed portion 344 of the connecting rod 342 is rotatably fixed to the inner lower end of the slider unit 3 by a structure such as a pivot or a hinge. That is, as shown in Figs. 12-15, the height adjusting part 34 can rotate around the fixed portion 344 as an axis (in fact, specifically, the pin shaft or the like, to fix the fixed portion 344, as an axis). Here, when the height adjusting part 34 rotates with the fixed portion 344 as an axis, the insertion and removal of the pin 343 into and from the pin holes 54 of the guide rail unit 5 can be achieved, to realize the fixation of the slider unit 3 with respect to the guide rail unit 5 and the releasing of the fixation, thereby adjusting the positions of the slider unit 3 and the swing arm unit 4 connected thereto.

[0092] Specifically, when the user needs to adjust the height position of the swing arm unit 4, here is the process. Just by clasping the adjusting handle 341 of the height adjusting part 34 with a hand of the user to apply an action force to the handle 341 in a counterclockwise direction in the state shown in Fig. 15, the height adjusting part 34 can rotate in a counterclockwise direction with the fixed portion 344 as an axis, so as to drive the pin 343 disposed at the connecting rod 342 to move towards the left side of Fig. 14, so that the pin 343 can be pulled out from the pin holes 54 of the guide rail unit 5. When the pin 343 is pulled out from the pin holes 54 of the guide rail unit 5, the slider unit 3 can slide freely on the guide rail unit 5, and at this point, just by continually clasping the adjusting handle 341 and pulling it up and down, the slider unit 3 can slide along the guide rail unit 5 up and down, so as to drive the swing arm unit 4 to move up and down along the guide rail unit 5. Then, when the slider unit 3 slides to the height position desired by the user, just by the user clasping the adjusting handle 341 to applying a clockwise action force thereto in the state shown in Fig. 15, the height adjusting part 34 can rotate in a clockwise direction with the fixed portion 344 as an axis, thus to drive the pin 343 disposed on the connecting rod 342 to move to the right side of Fig. 14, so that the pin 343 is inserted into the pin hole 54 in the guide rail unit 5 to realize position fixing of the slider unit 3 relative to the guide rail unit 5, thereby finishing the height adjustment.

[0093] Additionally, for ease of rotation of the height adjusting part 34, as shown in Figs. 12-15, a spring member 345 such as a coil spring, into the center of which the pin 343 can be inserted, may be provided. In the shown example, the spring member 345 can be kept between the flange portion of the pin 343 (the left end of the flange portion of the pin 343 in Fig. 15) and the housing of the slider unit 3 (e.g., the slider fixing seat 32) to prevent falling of the spring member 345 by providing the pin 343 with a flange portion (e.g., similar to the shape structure of a bolt head) having a step difference, and providing the flange portion of the pin 343 with the diameter larger than that of the spring member 345 as a coil spring. Here, preferably, when the pin 343 is inserted into the pin hole 54 of the guide rail unit 5, the spring member 345 is compressed, whereby it is possible to lock the position fixing of the slider unit 3 relative to the guide rail unit 5 by utilizing the thrust force exerted on the pin 343 when the spring member 345 abuts against the flange portion of the pin 343. Additionally, preferably, when the pin 343 is pulled out from the pin hole 54 of the guide rail unit 5, the spring member 345 can be further compressed, and thus when the slider unit 3 slides to a specified height position, the elastic restoring force of the spring member 345 can be utilized to assist the user in operating the height adjusting part 34 to reinsert the pin 343 into the pin hole 54, so that the positioning of the slider unit 3 with respect to the guide rail unit 5 is realized. The setting described above for the spring member 345 is only an example, and the abutting positions of both ends of the spring member 345 or the compression and extension in respective states may be changed, or one end of the spring member may be fixed to another component. Preferably, the spring member 345 is set, so that it can lock the relative fixation of the slider unit 3 to the guide rail unit 5 when the pin 343 is inserted into the pin hole 54 of the guide rail unit 5, and can assist in insertion when the pin 343 is pulled out from the pin hole 54 and inserted into another pin holes 54.

[0094] Additionally, in the present application, the specific shape of the connecting rod 342 is not limited, and may be the shape of an elongated rod with a rectangular or circular cross-section. Preferably, the connecting rod 342 is set to have a shape with a concave (grooved or coved) cross-section in consideration of the mounting and fixing of the pin 343 with respect to the pin mounting portion 346 and the rotatable fixing of the fixed portion 344, so that the pin 343 and the fixed portion 344 are easily mounted and fix by components such as an insertion shaft or a blot. Additionally, in view of factors such as the ease of inserting the pin 343 into the pin hole 54, as shown in Figs. 12-15 or Fig. 17 described below, preferably, the pin 343 is loosely (e.g., with certain rotation margin) mounted to the pin mounting portion 346 by a bolt or the like, the pin 343 has certain deviation margin, so that it is easier to insert and pull out the pin 343 into and from the pin hole 54 when the height adjusting part 34 is operated.

[0095] Additionally, in the shown example, the upper end portion of the connecting rod 342 is formed in a curved shape for ease of mounting the adjusting handle 341, so that the connecting rod 342 is substantially L-shaped. But the present application is not limited thereto, and the connecting rod 342 may be formed in other shapes.(Mode II)

[0096] In "Mode 1" above, description is made by a case, as an example, in which the height position of the slider unit 3 is adjusted by the operation of manually inserting and pulling out the pin into and from the pin hole. But the present application is not limited thereto, and other modes to insert and pull out the pin into and from the pin hole may be used. In the present application, as another mode to insert and pull out the pin into and from the pin hole to realize the position fixing of the slider unit 3 relative to the guide rail unit 5 and the release of the position fixing, for example, the height position of the slider unit 3 can be automatically adjusted by a motor, a cam structure or the like.

[0097] Specifically, as shown in Figs. 16-18, the height adjusting part 35, which can insert and pull out the pin 353 into the pin hole 54 and from the pin hole 54, is disposed within the slider unit 3, and mainly comprises: a connecting rod 352 which is substantially elongated rod-like; a cam abutting portion 351 fixedly mounted at an upper end portion (the upper portion in the up-and-down direction in Figs. 17 and 18) of the connecting rod 352; a pin mounting portion 358 disposed at the middle portion of the connecting rod 352; a fixed portion 354 disposed at the lower end portion of the connecting rod 352; and a pin 353 (a clamping pin), which is disposed at the pin mounting portion 358 and can be inserted into and pulled out from the pin holes 54 disposed in the bearing seat 51 of the guide rail unit 5.

[0098] In this embodiment, as shown in Figs. 16-18, substantially like the "Mode 1" described above, the connecting rod 352 is substantially linear, and disposed in an up-and-down direction. Additionally, in the embodiment, instead of the adjusting handle, the cam abutting portion 351 is fixedly disposed at the upper end portion of the connecting rod 352. In addition, the pin mounting portion 358 is also disposed at the middle portion of the connecting rod 352, to which the pin 353 can be mounted. The mode for mounting the pin 353 to the pin mounting portion 358 is also substantially the same as that described above in "Mode 1". For example, as shown in Figs. 17 and 18, the pin 353 can be mounted at the pin mounting portion 358 by insertion-shaft fixation modes in such a way that the pin 353 is substantially perpendicular with respect to the length direction of the connecting rod 352 (the up-and-down direction in Figs. 17 and 18). Here, as shown in Figs.17 and 18, when the height adjusting part 35 is mounted on the fitness equipment F, the guide rail unit 5 (the guide rail 52) and the connecting rod 352 as a whole extend linearly in the up-and-down direction, and the pin 353 is substantially perpendicular with respect to the length direction of the connecting rod 352, thus, the pin 353 is also substantially perpendicular with respect to the guide rail 52 (the guide rail unit 5), and the direction in which the pin 353 is inserted into the pin hole 54 is also substantially perpendicular with respect to the guide rail 52 (the guide rail unit 5).

[0099] Additionally, as shown in Figs. 16-18, this implementation further differs from the "Mode 1" described above in that the height adjusting part 35 includes a motor 356 having a rotating shaft and a cam 355 fixedly connected to the rotating shaft of the motor 356. As shown in Fig. 17, the cam surface of the cam 355 of the height adjusting part 35 in this mode can abut against the cam abutting portion 351. When the motor 356 rotates, the cam 355 also rotates. During the rotation of the cam 355, when the position where the cam abutting portion 351 abuts against the cam 355 gradually changes from the position having a relatively low height at the cam surface of the cam 355 to the position having a relatively high height at the cam surface, the cam surface of the cam 355 (a cam contour) exerts an action force to the cam abutting portion 351 abutting with the cam surface, so that the cam abutting portion 351 can be pushed away from the guide rail unit 5 (being pushed to the left in Figs. 17 and 18), thus the height adjusting part 35 as a whole can rotate with the fixed portion 354 as an axis (e.g., rotating in the counterclockwise direction with the fixed portion 354 as an axis in Figs. 17 and 18), and thus the pin 353 mounted at the pin mounting portion 358 can be driven to move away from the pin holes 54 in the guide rail unit 5, so as to pull out the pin 353 from the pin hole 54 in the guide rail unit 5, thereby releasing the fixation of the slider unit 3 to the guide rail unit 5.

[0100] Further, as the motor 356 rotates, when the position where the cam abutting portion 351 abuts against the cam 355 gradually changes from the position having a relatively high height at the cam surface of the cam 355 to the position having a relatively low height at the cam surface, the cam surface of the cam 355 (a cam contour) does not exert an action force to the cam abutting portion 351 abutting with the cam surface, so that the cam abutting portion 351 can return in the direction towards the guide rail unit 5 (being pushed to the right in Figs. 17 and 18), i.e., the height adjusting part 35 as a whole can rotate with the fixed portion 354 as an axis (e.g., rotating in the clockwise direction with the fixed portion 354 as an axis in Figs. 17 and 18), and thus the pin 353 mounted at the pin mounting portion 358 can be driven to be inserted into the pin holes 54 in the guide rail unit 5, so as to fix the slider unit 3 with respect to the guide rail unit 5.

[0101] Additionally, to gradually shift the abutting position of the cam portion 351 from the position having a relatively high height at the cam surface to the position having a relatively low height at the cam surface as the cam 355 rotates so as to reinsert the pin 353 into the pin hole 54, i.e., to fix the slider unit 3 with respect to the guide rail unit 5, the height adjusting part 35 may be further provided with a reset member. Specifically, as a specific example of the reset member, as shown in Figs. 16-18, the height adjusting part 35 is further provided with a spring member 357, such as a coil spring, etc., into the center of which the pin 353 can be inserted. In the shown example, in the mode the same as the "Mode I" described above, the spring member 357 can be kept between the flange portion of the pin 353 (the left end of the flange portion of the pin 353 in Fig. 17) and the housing of the slider unit 3 (e.g., the slider fixing seat 32) to prevent falling of the spring member 357 by providing the pin 343 with a flange portion (e.g., similar to the shape structure of a bolt head) having a step difference, and providing the flange portion of the pin 353 with the diameter larger than that of the spring member 357 as a coil spring. Here, preferably, when the pin 353 is inserted into the pin hole 54 of the guide rail unit 5, the spring member 357 is compressed, whereby it is possible to lock the position fixing of the slider unit 3 relative to the guide rail unit 5 by utilizing the thrust force exerted on the pin 353 when the spring member 357 abuts against the flange portion of the pin 353. Additionally, preferably, when the pin 353 is pulled out from the pin hole 54 of the guide rail unit 5, the spring member 357 can be further compressed, and thus when the slider unit 3 slides to a specified height position, the elastic restoring force of the spring member 357 can be utilized to reinsert the pin 343 into the pin hole 54 for positioning of the slider unit 3 with respect to the guide rail unit 5. The setting for the spring member 357 described above is only an example, and so, the abutting positions of both ends of the spring member 357 or the compression and extension in respective states can be changed, or one end of the spring member may be fixed to another component. Preferably, the spring member 357 is set, so that it can lock the relative fixation of the slider unit 3 to the guide rail unit 5 when the pin 353 is inserted into the pin hole 54 of the guide rail unit 5, and can assist in insertion when the pin 353 is pulled out from the pin hole 54 and inserted into another pin holes 54.

[0102] Additionally, regarding a specific operation process in this implementation, as shown in Figs. 16-18, when the slider unit 3 and the guide rail unit 5 are kept in a locked state when the pin 353 is kept in a state being inserted into the pin hole 54, the position where the cam abutting portion 351 abuts against the cam 355 is the position having a relatively low height at the cam surface, and at this point, the cam surface of the cam 355 does not apply an action force to the cam abutting portion 351 (or the cam surface of the cam 355 exerts only a very small force on the cam abutting portion 351, which force is not sufficient to rotate the height adjusting part 35). Additionally, by providing the spring member 357 and maintaining the spring member 357 in a compressed state at this time, one end of the spring member 357 abuts against for example the slider fixing seat 32 of the slider unit 3, and the other end abuts against the pin 353 to exert an action force on the pin 353, so that it can be further ensured that the pin 353 is inserted into the pin hole 54. Then, when the height position of the swing arm unit 4 needs to be adjusted, the motor 356 of the height adjusting part 35 is first activated to rotate the cam 355. As it rotates, the abutting position of the cam abutting portion 351 gradually shifts from the position having a relatively low height at the cam surface to the position having a relatively high height at the cam surface, thus, the cam surface (a cam contour) of the cam 355 can be utilized to apply an action force to the cam abutting portion 351 abutting against the cam surface, and to further resist the spring member 357 to compress it to push the cam abutting portion 351 away from the guide rail unit 5 (pushed to the left in Figs. 17 and 18), so that the height adjusting part 35 can rotate as a whole with the fixed portion 354 as an axis (for example, in Figs. 17 and 18, rotating in a counterclockwise direction with the fixed portion 354 as an axis). Thus, the pin 353 can be driven to move away from the pin hole 54 of the guide rail unit 5, and is pulled out from the pin hole 54 of the guide rail unit 5, releasing of the fixation of the slider unit 3 to the guide rail unit 5. At this point, the motor 356 stops, a state where the fixation of the slider unit 3 to the guide rail unit 5 is released is maintained, so that the slider unit 3 can slide on the guide rail unit 5. At this point, only by sliding the slider unit 3 up and down along the guide rail unit 5, the swing arm unit 4 can be driven to move up and down along the guide rail unit 5. Then, when the slider unit 3 slides to the position desired by the user, the motor 356 is restarted to further rotate (or reversely rotate) the cam 355, so that the position where the cam abutting portion 351 abuts against the cam 355 gradually changes from the position having a relatively high height at the cam surface to the position having a relatively low height at the cam surface. At this time, the spring member 357 needs to restore to the previous state, so that the spring member 357 can be utilized to drive the height adjusting part 35 as a whole, with the fixed portion 354 as the axis, to rotate in the direction opposite to the previous one (in Figs. 17 and 18, rotating in a clockwise direction), thus, the pin 353 disposed at the connecting rod 352 of the height adjusting part 35 is driven to move in the direction in which it is inserted into the pin hole 54 (in Figs. 17 and Fig. 18, moving right), and finally, the pin 353 is reinserted into the pin hole 54 of the guide rail unit 5, realizing position fixing of the slider unit 3 with respect to the guide rail unit 5, and finally finishing the height adjustment.

[0103] Additionally, like "mode 1" described above, the specific shape of the connecting rod 352 is not limited, and may be the shape of an elongated rod with a rectangular or circular cross-section. Preferably, the connecting rod 352 is set to have a shape with a concave (grooved or coved) cross-section in consideration of the mounting and fixing of the pin 353 with respect to the pin mounting portion 358 and the rotatable fixing of the fixed portion 354, so that the pin 353 and the fixed portion 354 are easily mounted and fixed by components such as an insertion shaft or a blot. Additionally, in view of factors such as the ease of inserting the pin 353 into the pin hole 54, as shown in Fig. 17, preferably, the pin 353 is loosely (e.g., with certain rotation margin) mounted to the pin mounting portion 358 by a bolt or the like, the pin 353 has certain deviation margin, so that it is easier to insert and pull out the pin 353 into and from the pin hole 54 when the height adjusting part 35 is operated.

[0104] Additionally, in this implementation, since the insertion and removal of the pin into and from the pin hole is realized by a motor and a cam structure, a control part or a control unit (not shown) and a button or the like can be further provided. By further electrically connecting the motor to the control part and the button, the insertion and removal of the pin into and from the pin hole can be controlled by simple touch control without requiring the user to manually hold the adjusting handle or the like, thereby realizing the fixation of the slider unit 3 with respect to the guide rail unit 5 and the releasing of the fixation. Here, for example, the control part or the control unit may be, but not limited thereto, a computer with a CPU or the like.

[0105] Additionally, since the height position sensor 55 is also provided along the length direction of the guide rail 52, the height position sensor 55 can automatically detect the height position of the slider unit 3, and is combined with the motor 6 realized as a resistance source to automatically adjust the height of the swing arm unit 4.

[0106] Specifically, for example, components, for example as control parts, such as a computer having a CPU and a memory (e.g., a hard disk, a RAM, a ROM, and an EEPROM) storing data and programs, are also provided in the main part 1, the above-described front panel 2 formed as a touch panel or an operation panel is used as an operation interface that can be operated by a user, and components such as the resistance source motor 6 and the motor 356 of the height adjusting part 35 are electrically connected to the control part, the operation interface, the height position sensor 55 and the like.

[0107] Here, when the user needs to adjust the height position of the slider unit 3 (the swing arm unit 4), the user can first set the target height to be adjusted. For example, the user can input the information about the target height position to be adjusted by an operation interface or the like, and store it in the memory. Additionally, the control part controls the height position sensor 55 to detect the current position of the slider unit 3, thereby obtaining the current height position information of the slider unit 3, and the information is stored in the memory. Then, the control part compares the target height position information set by the user with the current height position information detected by the height position sensor 55, and obtains a corresponding relation between the current height position of the slider unit 3 and the target height position, for example, the current height position of the slider unit 3 being higher or lower than the target height position, and the like.

[0108] Then, the control part controls the height adjusting part to release its locked state to enable the slider unit 3 to slide freely on the guide rail unit 5. Specifically, the control part controls the height adjusting part 35 to rotate the motor 356 of the height adjusting part 35, and thus the cam 355 fixed to the rotating shaft of the motor 356 rotates. During the rotation of the cam 355, the cam abutting portion 351 abutting against the cam 355 moves linearly following the cam surface (a cam contour) of the cam 355. At this point, when the position where the cam abutting portion 351 abuts against the cam 355 gradually changes from the position having a relatively low height at the cam surface of the cam 355 to the position having a relatively high height at the cam surface, the cam surface of the cam 355 (a cam contour) exerts an action force to the cam abutting portion 351 abutting with the cam surface, so that the cam abutting portion 351 can be pushed away from the guide rail unit 5 (being pushed to the left in Figs. 17 and 18), so that the height adjusting part 35 as a whole can rotate with the fixed portion 354 as an axis (e.g., rotating in the counterclockwise direction with the fixed portion 354 as an axis in Figs. 17 and 18), and thus the pin 353 mounted at the pin mounting portion 358 can be driven to move away from the pin holes 54 in the guide rail unit 5, so as to pull out the pin 353 from the pin hole 54 in the guide rail unit 5, thereby releasing the fixation of the slider unit 3 to the guide rail unit 5. That is, by control of the control part, the height adjusting part releases the locked state and causes the slider unit 3 to slide freely on the guide rail unit 5. At this point, the control part stops, to maintain the state where the slider unit 3 can slide freely on the guide rail unit 5.

[0109] Then, based on the corresponding relation, between the current height position of the slider unit 3 and the target height position, derived by comparing the target height position information set by the user with the current height position information detected by the height position sensor 55, when it is determined that the slider unit 3 needs to be raised, as shown in Fig. 32, the control part controls the resistance source motor 6 to rotate in the direction in which the rope R is wound onto the wire spool 7 (in Fig. 32, the marked resistance source motor 6 located at the relatively lower side rotates in a counterclockwise direction, and the unmarked resistance source motor located at the relatively upper side rotates in a clockwise direction), so that the handle (not shown, the position of the protruding end in Fig. 32) connected to the rope R is pulled upward by the rope R and abuts against the front end portion of the swing arm unit 4, and the slider unit 3 connected to the base end portion of the swing arm unit 4 is further driven to move upwards along the guide rail unit 5. Alternatively, based on the corresponding relation, between the current height position of the slider unit 3 and the target height position, derived by comparing the target height position information set by the user with the current height position information detected by the height position sensor 55, when it is determined that the slider unit 3 needs to be lowered, as shown in Fig. 32, the control part controls the resistance source motor 6 to rotate in the direction in which the rope R wound onto the wire spool 7 is released from the wire spool 7 (in Fig. 32, the marked resistance source motor 6 located at the relatively lower side rotates in a clockwise direction, and the unmarked resistance source motor located at the relatively upper side rotates in a counterclockwise direction), so that the handle (not shown) located at the front end side of the swing arm unit 4 is lowered by self-weight, and thus the swing arm unit 4 is no longer subjected to the upward action force exerted by the handle abutting against the front end portion of the swing arm unit 4, thereby the slider unit 3 and swing arm unit 4 also can slide downwards by self-weight along the guide rail unit 5.

[0110] Then, after the height position sensor 55 detects that the slider unit 3 moves to the target height position set by the user, the motor 356 of the height adjusting part 35 restarts and further rotates via control (the motor 356 of the height adjusting part 35 may also reversely rotate via control) to rotate the cam 355 fixed to the rotating shaft of the motor 356 again. During the rotation of the cam 355, as described above, the cam abutting portion 351 abutting against the cam 355 moves linearly following the cam surface (a cam contour) of the cam 355. At this point, when the position where the cam abutting portion 351 abuts against the cam 355 gradually changes from the position having a relatively high height at the cam surface to the position having a relatively low height at the cam surface, the height adjusting part 35 rotates in the direction opposite to the direction just described (in Figs. 17 and 18, rotating in a clockwise direction) with the fixed portion 354 as an axis, thereby, the pin 353 disposed at the connecting rod 352 of the height adjusting part 35 is driven to move in the direction in which the pin 353 is inserted into the pin hole 54 (in Figs. 17 and Fig. 18, moving right), and finally, the pin 353 is reinserted into the pin hole 54 of the guide rail unit 5, realizing position fixing of the slider unit 3 with respect to the guide rail unit 5. That is, after the height position sensor 55 detects that the slider unit 3 moves to the target height position set by the user, the pin 353 is inserted into the pin hole 54 via control, so that the slider unit 3 and the guide rail unit 5 are in a locked state where they cannot move relative to each other.

[0111] At this point, the height adjustment of the slider unit 3 is finally completed. In the process, the user only needs to set the desired height position information, without complex adjustment operations, and the height position of the slider unit 3 can be automatically adjusted by skillfully utilizing the connection position relation among the resistance source motor and respective components.

[0112] Additionally, in the present application, the adjustment of the height position of the slider unit 3 actually is the adjustment of the height position of the base end portion of the swing arm unit 4 that is connected to the slider unit 3, thereby adjusting the height position of the swing arm unit 4.(Mode III)

[0113] As another specific example for inserting and removing a pin into and from a pin hole according to the present application, as shown in Figs. 19 and 20, a worm pin may also be used as a pin and be combined with a motor to realize the automatic insertion and removal of the worm pin into and from the pin hole.

[0114] Specifically, as shown in Figs. 19 and 20, within the slider unit 3, a height adjusting part 36 is disposed that can insert and remove the worm pin 361 into and from a pin hole 54. As shown in Figs. 19 and 20, the height adjusting part 36 mainly comprises, the worm pin 361 having helical teeth 366 on a part of its surface; a motor 363 having a rotating shaft; and a gear 362 fixed to a motor shaft, which can engage with the helical teeth 366 of the worm pin 361. In this implementation, as shown in Figs. 19 and 20, the worm pin 361 is rotatably fixed to the slider fixing seat 32 of the slider unit 3 and / or the swing arm fixing seat 41 of the swing arm unit 4 by the worm bearing 364 and the worm fixed member 365, etc., and the helical teeth 366 of the worm pin 361 always engage with the gear 362 on the rotating shaft of the motor 363, and the portion with no helical teeth 366 (e.g., the insertion portion 367 of the right side of the helical teeth 366 in Fig. 19) can be inserted as a fixing pin into the pin hole 54. Additionally, the motor 363 is electrically connected to a control switch, a control part or the like not shown.

[0115] In this implementation, the insertion portion 367 of the worm pin 361 can be inserted into the pin hole 54. When the height position of the slider unit 3 needs to be adjusted, just by controlling the motor 363 by the control part or control switch to pull out or insert the insertion portion 367 of the worm pin 361 from or into the pin holes 54 at different positions, the user can adjust the height position of the slider unit 3 according to actual use situations and exercises, and lock the slider unit 3 at a specified position at the guide rail 52 of the guide rail unit 5.

[0116] For example, in this implementation, when the control part receives a height adjustment instruction from the user, it starts rotation of the motor 363, the worm pin 361 engaging with the gear 362 mounted on the rotating shaft of the motor is driven to move (left-and-right moving in Fig. 19, and up-and-down moving in Fig. 20) by the gear 362, and thus, the insertion and pulling-out of the insertion portion 367 of the worm pin 361 into and from the pin hole 54 are enabled by driving by forwardly or reversely rotating the motor 363, to unlock or fix the slider unit 3 relative to the guide rail unit 5 (the guide rail 52).

[0117] More specifically, in a specific example, when the user needs to adjust the height position of the slider unit 3, the user sends an adjustment indication to a control part by a specialized switch, a touch screen and a switch on the front panel 2, or the like. Upon receiving the height adjustment indication from the user, the control part starts the motor 363, for example, rotating the motor 363 forwardly, the worm pin 361 engaging with the gear 362 mounted on the rotating shaft of the motor is driven by the gear 362 to move in the unlocking direction (the worm pin 361 moving left in Fig. 19, and the worm pin 361 moving upward in Fig. 20), and thus, the insertion portion 367 is pulled out from the pin hole 54, followed by stopping the operation of the motor 363. At this time, the locking between the slider unit 3 and the guide rail unit 5 is released, the slider unit 3 can slide on the guide rail unit 5, and by simply sliding the slider unit 3 up and down along the guide rail unit 5, the swing arm unit 4 may be driven to move up and down along the guide rail unit 5. Then, when the slider unit 3 slides to the position desired by the user, the motor 363 is restarted to reversely rotate (a direction opposite to the rotation direction when the locking is released), the worm pin 361 engaging with the gear 362 mounted on the rotating shaft of the motor is driven by the gear 362 to move in the locking direction (in Fig. 19, moving the worm pin 361 right, and in Fig. 20, moving the worm pins 361 downward), and thus, the insertion portion 367 is reinserted into the pin hole 54, followed by stopping the operation of the motor 363. At this point, the slider unit 3 and the guide rail unit 5 are in a locked state, thereby realizing the position fixing of the slider unit 3 with respect to the guide rail unit 5, and finally completing the height adjustment.

[0118] Additionally, since the height position sensor 55 is also provided along the length direction of the guide rail 52, the height position sensor 55 can automatically detect the height position of the slider unit 3, and is combined with the motor 6 realized as a resistance source to automatically adjust the height of the swing arm unit 4.

[0119] Specifically, since the locking and unlocking of the slider unit 3 with respect to the guide rail unit 5 in the present application can be realized without pushing or pulling the slider unit 3 by hands, the fixation of the swing arm unit 4 can be automatically released, to automatically adjust the height of the swing arm unit 4.

[0120] For example, if an adjustment is needed to raise the swing arm unit 4, when the user starts to use the fitness equipment and is ready to adjust the height position of the swing arm unit 4, the user can input the information about the height position to be adjusted by for example the touch screen of the front panel 2. After a control unit (e.g., a computer, etc.) receives the height adjustment instruction from the user, at first, the motor 363 rotates, to use the gear 362 on the motor 363 to withdraw the worm pin 361 (moving left in Fig. 19 and upwardly in Fig. 20), so that the worm pin 361 is disengaged from the pin hole 54, thereby releasing the locking of the slider unit 3 with respect to the guide rail unit 5, and as a whole, the slider unit 3 and the swing arm unit 4 (the base end portion of the swing arm unit 4) can slide freely along the guide rail unit 5.

[0121] At this time, when it is desired to raise the height position of the swing arm unit 4, the motor 6 as a resistance source is controlled just by the control unit to rotate the motor 6 in the direction in which the rope R is wound onto the wire spool 7 (rotating the rope R in the direction in which it is tightened); and by the action of causing the rope R to be wound onto the wire spool 7, according to the resistance transmission relation between the rope R and the swing arm unit 4 as shown in Fig. 32, the handle (not shown) located at the front end of the swing arm unit 4 raises with the winding of the rope R and is stuck at the front end portion of the swing arm unit 4 (roughly at the position shown by the wrist-joint pulley d5 and the protruding end in Fig. 32) to raise the swing arm unit 4 and the slider unit 3. Then, when the height position sensor 55 detects that the swing arm unit 4 and the slider unit 3 raise to a specified position, it again sends a command to stop the operation of the motor 6 to the control unit, thereby the swing arm unit 4 and the slider unit 3 may be positioned at a specified height position.

[0122] Then, the motor 363 rotates by the control unit in a direction opposite to the direction described above, the worm pin 361 goes forward by utilizing the engaging of the gear 362 on the motor 363 with the helical teeth 366 on the worm pin 361, and is inserted into the pin hole 54, thereby locking the slider unit 3 with respect to the guide rail unit 5, so that the slider unit 3 and the swing arm unit 4 as a whole are fixed at a specified position, completing the upward adjustment for the swing arm unit 4.

[0123] Additionally, if an adjustment is needed to lower the swing arm unit 4, when the user starts to use the fitness equipment and is ready to adjust the height position of the swing arm unit 4, the user can input the information about the height position to be adjusted by for example the touch screen of the front panel 2. After a control unit receives the height adjustment instruction from the user, at first, the motor 363 rotates, to use the gear 362 on the motor 363 to withdraw the worm pin 361 (moving left in Fig. 19 and upwardly in Fig. 20), so that the worm pin 361 is disengaged from the pin hole 54, thereby releasing the locking of the slider unit 3 with respect to the guide rail unit 5, so that the slider unit 3 and the swing arm unit 4 as a whole can slide freely along the guide rail unit 5.

[0124] At this point, when it is desired to lower the height position of the swing arm unit 4, the motor 6 as a resistance source is controlled by the control unit to rotate the motor 6 in a direction in which the rope R is pulled out from the wire spool 7 (so that the rope R wound onto the wire spool 7 is in an unwound state). At this time, since the slider unit 3 and the swing arm unit 4 as a whole are in a state where they can slide freely along the guide rail unit 5, and the rope R wound onto the wire spool 7 is in the unwound state, the slider unit 3 and the swing arm unit 4 are not constrained by the rope R, and can slide freely downward along the guide rail unit 5 by self-weight. According to the resistance transmission relation between the rope R and the swing arm unit 4 as shown in Fig. 32, the swing arm unit 4 abuts against the handle located at the front end of the swing arm unit 4, and since the rope R of the bobbin winding 7 is in the unwound state at this time, the swing arm unit 4 drives the swing arm unit 4 to go downward while the swing arm unit 4 abuts against the handle. When the height position sensor 55 detects that the swing arm unit 4 and the block unit 3 lower to a specified position, an instruction signal is transmitted to the control unit, which instruction signal is to stop the rotation of the motor 6 and to maintain the power that can enable the swing arm unit 4 and slider unit 3 not to move (i.e., the power of the motor 6 can at least resist the gravity of the slider unit 3 and swing arm unit 4, and thus, the slider unit 3 and the swing arm unit 4 cannot continually slide freely), so as to fix the swing arm unit 4 and the slider unit 3 at the specified position.

[0125] Then, the motor 363 rotates by the control unit in a direction opposite to the direction described above, the worm pin 361 goes forward by utilizing the engaging of the gear 362 on the motor 363 with the helical teeth 366 on the worm pin 361, and is inserted into the pin hole 54, thereby locking the slider unit 3 with respect to the guide rail unit 5, so that the slider unit 3 and the swing arm unit 4 as a whole are fixed at a specified position, completing the downward adjustment for the swing arm unit 4.

[0126] By the present application, the height of the swing arm can be automatically adjusted and there is no need for the user to manually adjust the heights of the swing arms at both sides one by one. Even for a multiple-movement comprehensive training that targets different body parts, the height of the swing arm can be accurately and quickly switched, and the user does not need to worry about improper adjustments, and can accurately complete an adjustment operation all at once. Thus, the user can devote themselves to the exercise, bringing good use experience for the user.

[0127] Additionally, "Mode III" is used as an example to describe the automatic height adjustment in the above, and similarly, the automatic height adjustment is also applicable to "Mode II".(Mode IV)

[0128] Description is made above taking the pin and pin hole as examples. However, electromagnetic locking blocks that can be electromagnetically attracted to each other may also be provided. That is, instead of the pin and pin hole, a locking member and a locked part are provided, and are formed in the form of an electromagnetic lock. In this way, the guide rail unit 5 does not need to be perforated to provide pin holes, improving the strength of the guide rail unit 5, and without being limited by the number and position of the pin hole, the slider unit 3 can be locked at an arbitrary position in the length direction of the guide rail unit 5, so that a fine adjustment is possible for height positions, thereby resulting better user experience for the user. Additionally, the use of the electromagnetic lock allows a compact structure.

[0129] Additionally, when electromagnetic locking blocks which can be electromagnetically attracted to each other are provided, the height position can be automatically adjusted by controlling the resistance source motor 6 using the control part, as described in the above modes. That would be omitted.-Swing Arm Self-Receiving Structure-

[0130] The above describes the position fixing and releasing thereof of the slider unit with respect to the rail unit, and describes the height adjustment mode when the fitness equipment of the present application is used. Additionally, when the fitness equipment is not used, such as at the end of exercises, a swing arm of prior-art fitness equipment usually is set in the state for the last exercise routine and is not received.

[0131] In this regard, in the present application, the resistance source motor 6 can be controlled using the control part, to enable the slider unit 3 and the swing arm unit 4 to return to a receiving state. For example, a program can be prestored in a storage part, the control part performs control when it receives a receiving instruction from the user, so that the resistance source motor 6 rotates in the direction in which the rope R is wound onto the wire spool 7, and thus, as described above, components such as the handle disposed at the front end of the swing arm unit 4 abut against the front end portion of the swing arm unit 4 to drive the swing arm unit 4 and slider unit 3 to raise to the receiving position as shown in Fig. 4, thereby automatically receiving the swing arm unit 4. Here, after automatically receiving the swing arm unit 4, the control part can further perform control to automatically cut off the power supply to the fitness equipment.

[0132] In addition, the resistance source motor 6 can be controlled using the control part, so that the slider unit 3 and the swing arm unit 4 automatically return to the receiving state when the fitness equipment is in an idle state. For example, the idle time (standby time) can be preset for the fitness equipment and stored in the storage part. After a specified period for the fitness equipment, the control part automatically performs control, so that the resistance source motor 6 rotates in the direction in which the rope R is wound onto the wire spool 7, and thus, as described above, components such as the handle disposed at the front end of the swing arm unit 4 abut against the front end portion of the swing arm unit 4 to drive the swing arm unit 4 and slider unit 3 to raise to the receiving position as shown in Fig. 4, thereby automatically receiving the swing arm unit 4 when the fitness equipment is in the idle state. At this time, after automatically receiving the swing arm unit 4 during the idle state, the control part can further perform control to automatically cut off the power supply to the fitness equipment.

[0133] Thus, not only is it possible to quickly receive the swing arm unit after exercises, but also it is possible to automatically receive the swing arm unit and cut off the power supply after a period of idle time, which not only enables tidy home environment, but also saves energy.-Angle Adjustment Structure of Swing Arm of Swing Arm Unit

[0134] The above mainly describes the movement of the slider unit 3 and swing arm unit 4 in the up-and-down direction along the guide rail unit 5. Thus, the user can adjust the height position of the slider unit 3 and fix it at a desired fixed position on the guide rail unit 5 after the adjustment. However, even if the slider unit 3 and swing arm unit 4 are fixed at the desired fixed positions, sometimes the position of the swing arm 42 of the swing arm unit 4 needs to be adjusted, for example, in a vertical plane, depending on the height of the user and an exercise routine. For example, as shown in Fig. 10, the base end portion of the swing arm unit 4 is fixed to the slider unit 3, but the front end portion (the swing arm 42) of the swing arm unit 4 needs to rotate by a specified angle around the base end portion (around the slider unit 3) in the vertical plane (in the state shown in Fig. 1) and can be fixed at a desired angle.

[0135] In the present application, by designing the structure of the swing arm unit 4, as described below, the angle change for the swing arm 42 of the swing arm unit 4 in the vertical plane is realized by utilizing the adjusting pin 424 and the adjusting-pin fixing disk 425.

[0136] Specifically, as described in Figs. 21-25, the swing arm 42 has: a swing-arm main part 421 which is substantially strip-like; a base connection part 422 fixed to the base end side of the swing-arm main part 421 and rotatably connected to the swing arm fixing seat 41; an adjusting pin 424 which can extend or retract from the base end side of the swing-arm main part 421 in the length direction of the swing-arm main part 421 in the interior of the swing-arm main part 421; and an adjusting-pin fixing disk 425 which is substantially disk-shaped, which is fixed to the swing arm fixing seat 41 and on which a plurality of clipping opening 429 into which the adjusting pin 424 can be inserted and clamped are provided.

[0137] In the embodiment of the present application, as shown in Fig. 22, the base connection part 422 is fixed to the base end side of the swing-arm main part 421, and the base connection part 422 and the swing-arm main part 421, as a whole, are rotatably mounted to the swing arm fixing seat 41 by a structure such as a bearing or a clamping structure, and thus, the swing-arm main part 421 can rotate with the base connection part 422 as the center (an axis). In the implementation, preferably, the swing-arm main part 421 is formed in a hollow cylindrical shape.

[0138] Additionally, an adjusting-pin fixing disk 425, which is substantially disk-shaped, is also disposed on the swing arm fixing seat 41. In the shown example, the adjusting-pin fixing disk 425 is fixedly mounted in a substantially vertical direction to the swing arm fixing seat 41, and a plurality of clipping opening 429, into which the adjusting pin 424 can be inserted and clamped, are disposed in the adjusting-pin fixing disk 425 at its outer side in the circumferential direction, i.e., the adjusting-pin fixing disk 425 is substantially in the shape of an indexing disk. Here, the spacings between adjacent two of the plurality of clipping opening 429 may be equal or different as required. In the shown example, as shown in Figs. 22 and 23, the swing arm unit 4 is in a vertical state (e.g., a receiving state), in which for example the swing arm unit 4 is received, along the extension direction of the guide rail unit 5 when the adjusting pin 424 is inserted into the lowermost clipping opening 429. Additionally, as shown in Fig. 23, starting from the lowermost clipping opening 429, other clipping openings 429 are formed around the periphery of the adjusting-pin fixing disk 425 in a clockwise direction, and when the adjusting pin 424 is inserted into the clipping opening 429 other than the lowermost one, the swing-arm main part 421 is changed from the vertical state along the extension direction of the guide rail unit 5 to a rotational state, and at this point, it is a state in which the angle of the swing arm unit 4 is adjusted. Here, for ease of operations, the distance between the lowermost clipping opening 429 and another clipping opening 429 immediately adjacent thereto may be set to be greater than the distance between other clipping openings 429 other than lowermost clipping opening 429 (the lowermost clipping opening for receiving and others for adjusting). Figs. 24 (a)-(c) schematically show the process for moving the adjusting pin 424 from one clipping opening 429 to another one, but the above process and the set spacing are merely illustrative and may be modified as required.

[0139] Additionally, as shown in Fig. 23, the adjusting pin 424 that can extend or retract, inside the swing-arm main part 421, from the base end side of the swing-arm main part 421 along the length direction of the swing-arm main part 421 is also provided with inside the swing-arm main part 421. When the adjusting pin 424 extends and is clamped to one of the clipping openings 429 of the adjusting-pin fixing disk 425, the swing arm 42 as a whole can be locked at the rotation angle corresponding to the clipping opening 429; when the adjusting pin 424 retracts to the swing-arm main part 421, the clamping of the adjusting pin 424 to the clipping opening 429 of the adjusting-pin fixing disk 425 is released, and the swing-arm main part 421 can rotate, for example in the state shown in Fig. 6, in the vertical plane with the base connection part 422 as the center.

[0140] For the specific mode for extending the adjusting pin 424 and clamping it to the clipping opening 429 of the adjusting-pin fixing disk 425, see Figs. 21-25, a connecting rod 426 and an adjusting switch 427 are also provided inside the swing-arm main part 421, and the connecting rod 426 has an end connected to the tail end of the adjusting pin 424 (the end opposite to the end where the adjusting pin 424 is inserted into the clipping opening 429), and the other end connected to the adjusting switch 427.

[0141] Here, in the embodiment, as shown in Fig. 25, the adjusting switch 427 is set to be substantially L-shaped, and is rotatably mounted to the swing-arm main part 421 by a pin at the corner point of the L-shape adjusting switch 427, so that it can rotate with the pin as the center (the L-shaped adjusting switch 427 in Fig. 25 can rotate clockwise or counterclockwise with the pin as the center) .

[0142] Additionally, one of ends of the L-shaped adjusting switch 427 is rotatably fixed to, within the swing-arm main part 421, one end of the connecting rod 426. That is, as shown in Fig. 25, for the L-shaped adjusting switch 427 and connecting rod 426, the L-shaped adjusting switch 427 and the connecting rod 426 are formed as a planar link mechanism by fixing the corner point of the L-shaped adjusting switch 427 to the swing-arm main part 421. Here, as shown in Fig. 25, when the free end of the adjusting switch 427 rotates clockwise, the other end of the adjusting switch 427 connected to the connecting rod 426 pulls the connecting rod 426, so that it moves toward the upper portion of Fig. 25 (the front end side of the swing arm); when the free end of the adjusting switch 427 rotates counterclockwise, the other end of the adjusting switch 427 connected to the connecting rod 426 pushes the connecting rod 426 to move toward the lower portion of Fig. 25 (the base end side of the swing arm). Here, since the base end side of the connecting rod 426 is connected to the tail end of the adjusting pin 424, the adjusting pin 424 at the base end side of the connecting rod 426 moves up and down as the connecting rod 426 moves up and down due to the rotation of the adjusting switch 427, thereby realizing the insertion and removal of the adjusting pin 424 into and from the clipping opening 429.

[0143] Additionally, preferably, the base end side of the swing-arm main part 421 is provided with a pin slot 430 for sliding the adjusting pin 424, and a spring 428 for assisting in up-and-down moving of the adjusting pin 424 is disposed between the adjusting pin 424 and the bottom of the pin slot 430.

[0144] As described above, by configuring the interior of the swing arm 42 in the application, the angle of the swing arm 42 can be adjusted by operating the adjusting switch 427 at the tail end of the swing-arm main part 421.

[0145] Also, in the present application, the adjusting-pin fixing disk 425 may be integrated with the swing arm fixing seat 41, as shown in Figs. 12 and 16, or provided as a separate component, as shown in Fig. 19, without limitation thereto. Also, as shown in Figs. 12, 16, 19, and 22, the base housing 423 may be disposed at the base end side of the swing-arm main part 421, so that it is a component rotatable relative to the swing arm fixing seat 41.-Elastic Pulley Module-

[0146] As shown in Fig. 12 and Figs. 26-30, the slider unit 3 further includes an elastic pulley module 33 including, as shown in Figs. 26-30, a module frame 331, a module pulley 332, and a foot socket 333. Additionally, as shown in Fig. 12 and Figs. 26-30, the swing arm unit 4 further includes a foot part 44 disposed on the swing arm fixing seat 41. Additionally, as shown in Fig. 27, the guide rail unit 5 further includes a pulley rail 53 disposed on the bearing seat 51. In a mode for connecting the swing arm unit 4 to the slider unit 3 in the present application, two module pulleys 332 are disposed in the elastic pulley module 33 in the shown example, the module pulleys 332 are disposed on the module frame 331 via bearings, shaft holes or the like, and can slide along the pulley rail 53 on the bearing seat 51 of the guide rail unit 5, and the foot socket 333 is disposed in the module frame 331 and the foot part 44 of the swing arm unit 4 can be inserted into the foot socket 333. That is, as shown in Figs. 12 and 13, when the slider 31 of the slider unit 3 slides along the guide rail 52 of the guide rail unit 5, the swing arm unit 4 also slides, and since the foot part 44 disposed on the swing arm fixing seat 41 of the swing arm unit 4 is inserted into the foot socket 333 of the elastic pulley module 33, the elastic pulley module 33 also slides along the pulley rail 53 of the guide rail unit 5 as the swing arm unit 4 moves. That is, the slider 31 of the slider unit 3 slides along the guide rail 52 of the guide rail unit 5, the swing arm unit 4 connected to the slider 31 via the slider fixing seat 32 and the plain shaft 43 also slides, and the elastic pulley module 33 slides along the pulley rail 53 of the guide rail unit 5 since the foot part 44 of the swing arm unit 4 is inserted into the foot socket 333 of the elastic pulley module 33.

[0147] By such connection of the swing arm unit 4 with the slider unit 3, when the user takes training using the fitness equipment F, if an external force is loaded to the swing arm unit 4, the external force is not completely applied to the guide rail 52 of the guide rail unit 5, but is partially borne by the elastic pulley module 33. In the fitness equipment, the guide rail 52 is mainly used to adjust the height positions of the slider unit 3 and swing arm unit 4, and thus needs to be smooth and highly precise. When the guide rail 52 is excessively loaded by an external force, its precision and service life may be degraded. If multiple guide rails 52 are used or the width of the guide rail 52 is increased, the product manufacturing precision and the guide installation precision (for maintaining parallelism) need to be correspondingly improved, resulting in complicated installation and increased cost. Particularly, in the application, two guide rail units 5 are not parallel, but extend linearly and intersect in the extension direction, so that when the swing unit 4 is loaded by an external force, the life of the guide rail unit 5 (the guide rail 52) is more likely to be degraded. In this regard, in the present application, by providing the elastic pulley module 33 and enabling it to slide along the pulley rail 53, the elastic pulley module 33 is located at a corresponding height position regardless of the position of the slider unit 3; and due to the elasticity of the elastic pulley module 33, the foot part 44 can be located in the middle position of the pulley rail 33 when it is not loaded by a relatively large external force, thus, the foot part 44 does not contact with the pulley rail 33 and does not create friction, and when the slider unit 3 moves along the guide rail unit 5, it is very smooth and noiseless. When the swing arm unit 4 is loaded by an external force and it is transmitted to the slider unit 3, the elastic pulley module 33 deforms, the foot part 44 and the pulley rail 33 contact with each other to share the external force, and the external force loaded to the guide rail 52, and thus the guide rail 52 is not directly loaded and is protected.

[0148] Additionally, since it is required that the slider 31 smoothly slides along the guide rail 52, the precision between the slider 31 and the guide rail 52 should be maintained. In the present application, even if the precision between the slider 31 and the guide rail 52 is temporarily degraded by an external force, such as a slight offset of the slider 31 relative to the guide rail 52, the provided elastic pulley module 33 can correct the precision between the slider 31 and the guide rail 52 to restore the precision to its original state, thereby further protecting the guide rail 52 and enabling smooth sliding.

[0149] Additionally, as shown in Fig. 27, preferably, on the bearing seat 51 of the guide rail unit 5, a certain angle (the angle α as shown) is formed between the plane of the guide rail 52 for sliding the slider 31 and the plane of the pulley rail 51 for sliding the elastic pulley module 33. As shown, when the slider 31 of the slider unit 3 is loaded by an external force and squeezes the guide rail 52, usually in the direction transverse to the extension direction of the guide rail 52 (in the direction perpendicular to the extension direction of the guide rail 52 within the sliding plane of the slider 31). In this regard, in the present application, on the bearing seat 51 of the guide rail unit 5, by the angle formed between the plane of the guide rail 52 for sliding the slider 31 and the plane of the pulley rail 51 for sliding the elastic pulley module 33, the elastic pulley module 33 can share an external force when it is applied to the guide rail 52, thereby further protecting the guide rail 52 and ensuring more smooth sliding. Here, preferably, the angle α is, but not limited to, an obtuse angle, and may also be other angles.

[0150] Additionally, as described above, in the present application, by utilizing the foot part 44 disposed on the swing arm fixing seat 41 of the swing arm unit 4, and inserting the foot part 44 into the foot socket 333 provided in the module frame 331, the swing arm fixing seat 41 can be connected to the elastic pulley module 33 via a simple structure. Thus, the slider 31 of the slider unit 3 slides on the guide rail 52 of the guide rail unit 5, and the slider unit 3 is also connected to the swing arm unit 4, so that the swing arm unit 4 also slides as the slider unit 3 slides. On the other hand, the swing arm fixing seat 41 of the swing arm unit 4 is connected to the elastic pulley module 33, and it slides on the pulley rail 53 of the guide rail unit 5, so that the swing arm unit 4 also slides as the pulley module 33 slides, and since the swing arm unit 4 is also connected to the slider unit 3, the slider unit 3 also slides due to the sliding of the elastic pulley module 33. That is, the swing arm unit 4 and the slider unit 3 slide along the guide rail unit 5 via the slider 31 and the elastic pulley module 33. The external force, whether it is applied to the swing arm unit 4 or the slider unit 3, can be shared via the elastic pulley module 33, so that the impact to the guide rail 52 can be reduced, thereby further protecting the guide rail 52 and ensuring smooth sliding.

[0151] Further, in an embodiment of the present application, preferably, the module pulley 332 is a grooved pulley with a slot, and the surface of the pulley rail 53 in contact with the grooved pulley is formed in a shape that can fit with the slot. Additionally, as shown in Figs. 27 and 28, more preferably, the module pulley is a V-slot or U-slot pulley, and there are two module pulleys, each of which is located at one of front and rear ends of the module frame 331. Thus, it is possible to share the external force applied to the guide rail 52 more stably.

[0152] Description is made above by the example in which the elastic pulley module of the present application is a cushioning member. However, the present application is not limited thereto, and various changes can be made.-Mode of Connecting Slider Unit to Guide Rail Unit-

[0153] Additionally, regarding the mode for slidably mounting the slider unit 3 on the guide rail unit 5, it may be, for example, a structure in which a sliding chute is disposed at the guide rail unit 5 and the slider unit 3 is embedded in the sliding chute, or a structure in which the guide rail unit 5 is formed as an I-shaped rail and the slider unit 3 is embedded therein, or a combination of a sliding chute and a roller or the like, as long as the slider unit 3 can slide along the guide rail unit 5.-Other Embodiments-

[0154] As shown in Figs. 1-10, description is made above by the case, as an example, in which the left guide rail unit 5 and the right guide rail unit 5 have the tendency to intersect in respective extension directions as they go upward (the top edge 23 of the main part 1). But the present application is not limited thereto, and it may also be designed that the left guide rail unit 5 and the right guide rail unit 5 have the tendency to intersect in respective extension directions as they go downward (the bottom edge 24 of the main part 1), or other modes are also possible. Further, description is made by taking, as an example, the case in which the front panel 2 is rectangular. But the present application is not limited thereto, and other shapes, such as a circular shape, or an oval shape, are possible. That is, in the present application, it is only required that the extension directions of the two guide rail units 5 are not parallel and have an angle therebetween. Here, the non-parallel positional relation of the guide rail units 5 can be utilized to form a receiving area for the slider unit 3 and the swing arm unit 4, and the front panel 2 can be utilized to shield the slider unit 3 and the swing arm unit 4 in the receiving state.

[0155] As specific embodiments of other cases, for example, the main part may be formed in an isosceles trapezoid shape in which the length of the upper base is longer than that of the lower base (e.g., the inverted state of the main part 1 as shown in Figs. 3 and 31), and rail units are provided along the side edges of the main part. Here, on the contrary to the above embodiments, the two guide rail units have the tendency to intersect along the side edges of the main part as they go downward along the fitness equipment. In the embodiment, in the receiving state, the slider unit is located at the lower end of the guide rail unit, and when the user wants to use the fitness equipment, the user just lifts the slider unit to the specified position at the guide rail unit.

[0156] In addition, like the embodiment described above, the shape of the main part may be not limited, as long as the two guide rail units are set in such a way that they have the tendency to intersect as they go toward the lower portion of the fitness equipment, with the same effect that can be obtained.

[0157] As described above, in the present application, only by cleverly utilizing the guide rail units and front panel without providing dedicated components, the swing arm unit and the slider unit can be completely hidden behind the back side of the fitness equipment F (the front panel) in the receiving state, so that the swing arm connection structure can be completely hidden in the receiving state. By this way, the fitness equipment can have a more integrated design, and when being not used in the receiving state, the fitness equipment is more aesthetically pleasing, and is suitable for use at home. In particular, when the fitness equipment is idle, it is neat and of a small size since the swing arm connection structure does not protrude sideways and is completely hidden, thus the equipment has a smaller body and more aesthetical appearance, and any other components except the front panel cannot be seen at all in the receiving state. Especially when the front panel is a mirror display, the fitness equipment in the receiving state can be used as an entertainment display device when power on, and even as an ordinary mirror when power off; and thus, the fitness equipment has neat and aesthetic appearance; it can be easily placed for use in a house; and fitness equipment can be utilized for other purposes even when it is idle, and does not destroy the layout of a room due to its placement at home.

[0158] Additionally, the present application can be suitable for strength training with the swing arm at different heights according to various demands, and achieve multiple exercises by only one fitness equipment, and it is easy to use. The fitness equipment not only has a compact structure without taking up big space, but also has neat and aesthetic appearance, and does not affect the overall aesthetics and layout even if it is placed in an ordinary family.

[0159] Additionally, for convenience of training activities conducted by users, such as deep squats, deadlift, back to back tug, etc., the rope needs to be positioned at a specified distance from a surrounding wall, so that its end is not jammed when the rope is pulled for respective training routines, especially when, for a low or high position, the protruding end of the rope (referring to Fig. 32, the end that is pulled out form the swing arm unit 4 when the rope R passes through the swing arm unit 4) needs cover a relatively large "protruding end range" for strength training. Thus, it is the difficulty and focal point to design a reasonable protruding end range. In some cases, if the "protruding end range" is to be satisfied, the fitness equipment needs to be disposed at a high height and the fitness equipment 2 itself needs to be high.

[0160] In the present application, the height position of the swing arm unit 4 can be adjusted up and down as the slider unit 3 slides, the effective length of the swing arm 42 can be increased, and thus, a relatively short swing arm 42 can cover a high-to-low height range for training. Here, as shown in Figs. 10, 31, and 32, when the fitness equipment F is hung on a wall for use in the state shown in Fig. 10 (e.g., as shown in Fig. 31, by mounting a mounting bracket 8 to a wall and mounting the main part 1 of the fitness equipment to the mounting bracket 8), since the fitness equipment F is hung on the wall at a certain distance from the floor and the position of the base end of the swing arm unit 4 can be adjusted up and down with the slider 3, the front end of the swing arm 42 of the swing arm unit 4 can easily meet the "protruding end range". Thus, the length of the swing arm 42 can be relatively short, so that the torque on the articulation point between the swing arm unit 4 and the slider unit 3 can be reduced. Additionally, since the base end of the swing arm unit 4 can move toward the floor along the guide rail unit 5, the front end of the swing arm unit 4 can be closer to the floor when the fitness equipment F is hung on a wall for use.

[0161] Specifically, for convenience of training activities conducted by users, such as deep squats, deadlift, back to back tug, etc., the protruding end of the rope (the end of the rope R which is pulled out by the handle) should cover a relatively large "protruding end range", such as 10 cm~2 m from the ground, and at least 60 cm from the wall surface.

[0162] In the present application, the position of the base end of the swing arm unit 4 can be adjusted up and down, so that the swing arm unit 4 can more easily fulfill the "protruding end range". For example, when the length of the swing arm is 98 cm, the base end of the swing arm unit 4 can move in the range of 90 cm - 122 cm from the ground during use to easily fulfill the "protruding end range", and thus, the swing arm 42 has a relatively short length, and the torque on the joint of the base end portion of the swing arm unit 4 connected to the slider unit 3 is small, facilitating to prolong the service life of the fitness equipment.

[0163] Specific implementations of the present application are described above. Those skilled in the art may make modifications and changes to the embodiments of the present application without departing from the spirit and scope thereof.
