[0009] An embodiment of the exercise equipment will be described below with reference to Figures 1 to 10. In this specification, unless otherwise specified, the vertical, horizontal, and depth directions refer to the direction when the exercise equipment 10 is placed on the floor, as shown in Figure 1.

[0010] <Composition of exercise equipment> As shown in Figure 1, the exercise equipment 10 is erected on the floor, which is the mounting surface. The exercise equipment 10 has a pair of left and right legs 20 that are positioned on the floor. Both legs 20 are rectangular prisms with a rectangular cross-section. The two legs 20 are positioned apart in the left-right direction. The two legs 20 extend longer in the front-back direction than in the left-right direction of the exercise equipment 10.

[0011] The exercise equipment 10 is equipped with a support column 30 between its two legs 20. The support column 30 is a rectangular prism with a rectangular cross-section. The support column 30 extends longer in the left-right direction than in the front-back direction of the exercise equipment 10. The longitudinal direction of the support column 30 is perpendicular to the longitudinal direction of the legs 20. The support column 30 maintains the distance between the legs 20 so as to ensure the stability of the exercise equipment 10.

[0012] Columnar support columns 40 are erected approximately in the center of the front-to-back direction of each leg portion 20. Both support columns 40 are rectangular prisms with a square cross-section. Both support columns 40 are hollow structures. Both support columns 40 are configured so that their hollow interiors are surrounded by four peripheral walls. Multiple through-holes H are formed in each peripheral wall of both support columns 40 at predetermined intervals in the direction in which the support column 40 extends. The through-holes H are opened in opposing positions in two peripheral walls that face each other.

[0013] The through-hole H in the support column 40 is used when attaching a predetermined mounting member to the support column 40. The mounting members can be broadly divided into two categories: those that perform auxiliary functions, such as ensuring safety, like barbell bars and safety bars, and those that directly apply load to the user's muscle groups, such as training bars 50. Figure 1 shows an exercise device 10 with a training bar 50, which can be attached using the through-hole H of the support column 40, attached to one of the support columns 40. Furthermore, another training bar 50 is attached to the upper ends of both support columns 40, between the two support columns 40. In the following description, the training bar 50 attached to one of the support columns 40 will be referred to as a dips bar 60. The training bars 50 attached to the upper ends of both support columns 40 will be referred to as chin-up bars 70.

[0014] <Dip bar configuration> The dip bar 60 is a bar that allows a user to support their own body by gripping a pair of grips with both hands and perform exercises by lifting and lowering the body through the flexion and extension of the elbows, thereby bearing their own body weight as a load. That is, the dip bar 60 is a bar for strengthening the action of pushing up the body by extending the upper limbs. As shown in FIGS. 2 and 3, the dip bar 60 includes a first support portion A1, a second support portion A2, a bar body 61, a shaft 62, and grips 63. Note that the dip bar 60 is used in a posture where the user places their body between the pair of grips 63 and holds the gripping portion G1 with both hands. Therefore, in the following description of the dip bar 60, with reference to the user who places their body between the pair of grips 63, the front and back as viewed from the user is the depth direction, the left and right is the left - right direction, and the up and down is the up - down direction.

[0015] When viewed from the up - down direction, the first support portion A1 is U - shaped so as to surround three sides of the support column 40. Specifically, the first support portion A1 includes a plate - shaped first member A11 that is arranged to face one side of the support column 40 when mounted on the support column 40. Further, the first support portion A1 includes a pair of plate - shaped second members A12 that are respectively arranged to face both side surfaces of the support column 40 adjacent to one side of the support column 40 when mounted on the support column 40. A circular mounting hole I is formed in the pair of second members A12. The mounting hole I has the same shape and size as the through - hole H shown in FIG. 1. And when the first support portion A1 is attached to the support column 40, the through - hole H and the mounting hole I overlap. The dip bar 60 can be mounted on the support column 40 by inserting a pin P that penetrates both the through - hole H and the mounting hole I in a state where the through - hole H and the mounting hole I overlap. Also, as shown in FIG. 3, a rod - shaped member Q that is inserted into the through - hole H of the support column 40 when mounted on the support column 40 is provided on the first member A11. The dip bar 60 is mounted on the support column 40 by inserting both the pin P inserted into the mounting hole I of the first support portion A1 and the rod - shaped member Q into the through - hole H of the support column 40.

[0016] The second support portion A2 includes a first connecting member A21 that connects the first support portion A1 and the bar main body 61, and a second connecting member A22. The first connecting member A21 is a prismatic member. The first connecting member A21 extends linearly from the first member A11 of the first support portion A1 toward the bar main body 61 and is provided along the horizontal direction. The second connecting member A22 is a prismatic member. The second connecting member A22 is provided so as to extend linearly in an oblique direction from a position on the first member A11 below the first connecting member A21 toward the bar main body 61.

[0017] The bar main body 61 includes a bar main body portion B1 connected to the second support portion A2, and a pair of side portions B2 having a plate shape. The bar main body portion B1 is a hollow square bar extending in the left - right direction of the dip bar 60. Note that the left - right direction of the dip bar 60 coincides with the left - right direction of the exercise apparatus 10 when the dip bar 60 is attached to the support column 40. Also, the central portion of the bar main body 61 is connected to the second support portion A2. Each side portion B2 has two ends spaced apart along the direction in which the second support portion A2 extends, that is, the depth direction of the dip bar 60. And one end portion of each side portion B2 is fixed to both ends of the bar main body portion B1.

[0018] The shaft 62 extends in the left - right direction of the dip bar 60, similar to the bar main body portion B1. The left - right direction of the dip bar 60 is also the extending direction of the bar main body portion B1 and the shaft 62. Also, the extending direction coincides with the left - right direction of the exercise apparatus 10 when the dip bar 60 is attached to the support column 40. Both ends of the shaft 62 are respectively fixed to the other end of each side portion B2, which is different from the end attached to both ends of the bar main body portion B1. Also, a plate - shaped central portion C through which the shaft 62 passes is attached to the first member A11 of the first support portion A1 and the first connecting member A21 of the second support portion A2. The central portion C receives the load applied to the long - shaped shaft 62.

[0019] As shown in Figure 2, the bar body B1 is provided with two insertion points S. Each insertion point S extends in the direction of extension of the bar body B1 and the shaft 62 and is located on a second surface that hangs down from a first surface that faces horizontally. The second surface is located in front of the user and is visible when the dips bar 60 is in use. The second surface is also the surface that is visible from the depth direction when the exercise equipment 10 with the dips bar 60 attached is installed. Each insertion point S is a comb-shaped hole drilled along the direction of extension of the bar body B1. Each insertion point S is located symmetrically on both sides with respect to the central part C. Each insertion point S has the same configuration.

[0020] Each insertion portion S comprises a first insertion portion S1 extending in the direction of extension of the bar body portion B1 and the shaft 62, and a plurality of second insertion portions S2 protruding downward in a direction perpendicular to the direction of extension of the first insertion portion S1. The first insertion portion S1 and the second insertion portions S2 are integrally formed. As will be described in more detail later, the insertion portion R of the grip 63 shown in Figures 4 and 5 can be inserted into the first insertion portion S1 and the second insertion portions S2. The insertion portion R is movable between the first insertion portion S1 and the second insertion portions S2. In this embodiment, each insertion portion S is provided with six second insertion portions S2 at predetermined intervals in the direction of extension of the first insertion portion S1.

[0021] As shown in Figures 2 and 3, a pair of left and right grips 63 are attached to the shaft 62. Each grip 63 is a handle portion that the user grasps when using the dips bar 60. Each grip 63 consists of a gripping portion G1 that the user grasps and a roughly rectangular prism-shaped grip body portion G2 to which the gripping portion G1 and the sliding member T are connected.

[0022] The grip body G2 has a gripping portion G1 of the grip 63 fixed to a first end located in the depth direction of the dips bar 60, and a sliding member T fixed to a second end located spaced apart in the depth direction from the first end. In the usage configuration of the dips bar 60, the first end is located on the front side, closer to the user, and the second end is located on the back side, further away from the user. The sliding member T has a configuration in which a linear ball bearing that assists linear motion is housed in a cylindrical case. The grip body G2 can slide in the direction of extension of the shaft 62 by inserting the shaft 62 through the sliding member T.

[0023] As shown in Figure 4, the grip body G2 has a plate-shaped portion PL extending downward at its first end. The grip body G2 also has an insertion portion R that protrudes in a rod-like manner from the surface of the plate portion PL facing the sliding member T.

[0024] As shown in Figures 2 and 3, the grip portion G1 penetrates both sides of the grip body G2 near the first end of the grip body G2 and is fixed in that position. The grip portion G1 comprises a curved portion that curves outward from the fixed portion of the grip body G2, and a straight portion that extends in the depth direction toward the user, continuous with this curved portion. In other words, the grip portion G1 has a J-shape when viewed from above or below.

[0025] As shown in Figure 4, the insertion part R is inserted into the second insertion part S2 with the shaft 62 inserted through the sliding member T. In this state, each grip 63 cannot move in the direction of extension of the shaft 62 between the side B2 and the central C of the bar body 61. Therefore, the movement of the grips 63 in the direction of extension of the shaft 62 is restricted. When the grips 63 are moved upward, which is perpendicular to the direction of extension of the shaft 62, as shown in Figure 5, the grips 63 rotate around the axis of the shaft 62 with the sliding member T as the center. In this state, the insertion part R is located in the second insertion part S2. Therefore, the grips 63 are allowed to move in the direction of extension of the shaft 62. In other words, the insertion part R can move in accordance with the movement of the sliding member T. In the following description, the upward direction is referred to as the first direction and the downward direction as the second direction in the vertical direction of the dips bar 60, that is, in the direction perpendicular to the direction of extension of the shaft 62.

[0026] <Functions related to the alignment of the dips bars> As shown in Figures 6(a) to 6(c), the grip 63 can change the position of the gripping portion G1 relative to the extending direction of the shaft 62. In Figure 6(a), the insertion portion R of the grip 63 is located at the second insertion portion S2. In this case, the grip 63 cannot move in the extending direction of the shaft 62.

[0027] In Figure 6(b), the gripping portion G1 is lifted in the first direction. When the gripping portion G1 is lifted in the first direction, the grip 63 rotates around the shaft 62. As the grip 63 rotates, the insertion portion R also moves. As the insertion portion R moves, it enters a first state in which it is inserted from the second insertion portion S2 into the first insertion portion S1. That is, the insertion portion R moves in a direction that separates it from the second insertion portion S2. In the first state, the position of the insertion portion R becomes variable in the extending direction of the shaft 62 while it is inserted into the first insertion portion S1. Therefore, the grip 63 becomes variable in its position between both ends of the shaft 62. In other words, movement of the grip 63 in the extending direction of the shaft 62 is permitted.

[0028] Figure 6(c) shows the state in which the grip 63 is moved, for example, from the position marked "6" in the figure to the position marked "3" when the grip 63 is in the first state. The grip 63 can be moved by the user holding the gripping part G1. When the user stops lifting the gripping part G1 in the first direction and moves it in the second direction, the insertion part R enters the second state in which it is inserted into the second insertion part S2. That is, the insertion part R moves in a direction that is relatively closer to the second insertion part S2. In the second state, the insertion part R is locked to the second insertion part S2. In other words, the grip 63 becomes immobile in the extending direction of the shaft 62 while inserted into the second insertion part S2. This state allows the grip 63 to be fixed in a position between both ends of the shaft 62.

[0029] Furthermore, the position of each grip 63 in the extension direction of the shaft 62 can be adjusted independently. Here, the grip 63 inserted through one end of the shaft 62 is referred to as the first grip, and the grip 63 inserted through the other end of the shaft 62 is referred to as the second grip. In this case, the adjustment of the first and second states of the first grip and the adjustment of the first and second states of the second grip can be performed independently. In addition, each grip 63 can be positioned in the same position or in different positions. Moreover, the position adjustment of the grips 63 can be performed at any time. That is, one can be adjusted and then the other adjusted, or only one or only the other can be adjusted.

[0030] <Chinning bar> The chin-up bar 70 is a bar that allows a user to exercise using their own body weight as resistance by suspending their body while gripping a pair of grips with both hands and moving their body up and down through flexion and extension of their upper limbs. Specifically, the chin-up bar 70 is a bar for strengthening the traction movement of the upper limbs. As shown in Figure 7, the chin-up bar 70 comprises a bar body 71, a shaft 72, and grips 73. The bar body 71 comprises a bar body section B1 made of a hollow square timber, and plate-shaped side sections B2 attached to the left and right sides of the bar body section B1. The shaft 72 is attached to the pair of side sections B2. A plate-shaped central section C is attached to the bar body section B1 in the center of the extension direction of the shaft 72, through which the shaft 72 passes. The central section C receives the load applied to the elongated shaft 72. The bar body section B1 has two insertion sections S. Each insertion part S is a comb-shaped hole perforated on the surface of the exercise equipment 10 that is visible from the depth direction when the equipment is installed. Each insertion part S is located symmetrically on both sides with respect to the central part C. Each insertion part S has the same configuration.

[0031] Each insertion portion S comprises a first insertion portion S1 extending in the direction of extension of the shaft 72, and a plurality of second insertion portions S2 projecting upward in a direction perpendicular to the direction of extension of the first insertion portion S1. The first insertion portion S1 and the second insertion portions S2 are integrally formed. The insertion portion S can accommodate the insertion portion R of the grip 73, which will be described later. The insertion portion R is movable between the first insertion portion S1 and the second insertion portions S2. In this embodiment, each insertion portion S has nine second insertion portions S2 provided at predetermined intervals in the direction of extension of the first insertion portion S1.

[0032] As shown in Figure 8, the grip 73 comprises a gripping portion G1 that serves as the user's handle, a grip body portion G2 located above the gripping portion G1, and a connecting portion G3 that is fixed to the grip body portion G2 and connected to the chin-up bar 70.

[0033] The connecting portion G3 comprises a sliding member T and an insertion portion R. The sliding member T has a configuration in which a linear ball bearing that assists linear motion is housed in a cylindrical case. A shaft 72 is inserted through the sliding member T. The sliding member T is slidable in the direction of extension of the shaft 72. The insertion portion R is a rod-shaped member. The insertion portion R is connected to the sliding member T and is provided protruding from the outer circumferential surface of the sliding member T such that the radial direction and depth direction of the sliding member T coincide.

[0034] As shown in Figure 8, with the shaft 72 inserted through the sliding member T, the insertion part R is inserted into the second insertion part S2. In this state, each grip 73 cannot move in the direction of extension of the shaft 72 between the side B2 and the center C of the chin-up bar 70. In this state, the grips 73 are restricted from moving in the direction of extension of the shaft 72. Also, in this state, as shown in Figure 9, if the grip 73 is moved towards the front in the depth direction, which is perpendicular to the direction of extension of the shaft 72, the grip 73 will rotate around the axis of the shaft 72 with respect to the sliding member T. In this state, since the insertion part R is located in the second insertion part S2, the grip 73 is allowed to move in the direction of extension of the shaft 72. In other words, the insertion part R can move in accordance with the movement of the sliding member T. In the following description, the front in the depth direction, which is perpendicular to the direction of extension of the shaft 72 in the chin-up bar 70, will be referred to as the first direction. Furthermore, the depth side of the depth direction, which is perpendicular to the extension direction of the shaft 72, is defined as the second direction.

[0035] <Functions related to the alignment of the chinning bar> As shown in Figures 10(a) to (c), the grip 73 can change the position of the gripping portion G1 with respect to the extending direction of the shaft 72. In Figure 10(a), the gripping portion G1 is lifted in the first direction. When the gripping portion G1 is lifted in the first direction, the sliding member T rotates around the shaft 72. As the sliding member T rotates, the insertion portion R also rotates. As the insertion portion R rotates, it enters a first state in which it is inserted from the second insertion portion S2 into the first insertion portion S1. That is, the insertion portion R moves in a direction that separates it from the second insertion portion S2. In the first state, the position of the insertion portion R is variable in the extending direction of the shaft 72 while it is inserted into the first insertion portion S1. Therefore, the gripping portion G1 is in a state in which its position between the two ends of the shaft 72 is variable. In other words, movement of the gripping portion G1 is permitted.

[0036] Figure 10(b) shows the state in which the gripping part G1 is in the first state and has been moved, for example, from the position marked "1" in the figure to a position between the positions marked "5" and "7". The movement of the grip 73 can be performed by the user holding the gripping part G1. Then, as shown in Figure 10(c), when the gripping part G1 is stopped from being lifted towards the user and moved in the second direction, the insertion part R enters the second state in which it is inserted into the second insertion part S2. That is, the insertion part R moves in a direction that is relatively closer to the second insertion part S2. In the second state, since the insertion part R is locked to the second insertion part S2, the gripping part G1 becomes immobile in the extending direction of the shaft 72 while inserted into the second insertion part S2. This state allows the gripping part G1 to be fixed in a position between both ends of the shaft 72.

[0037] Furthermore, the position of each grip 73 in the extension direction of the shaft 72 can be adjusted independently. Here, the grip 73 inserted through one end of the shaft 72 is referred to as the first grip, and the grip 73 inserted through the other end of the shaft 72 is referred to as the second grip. In this case, the adjustment of the first and second states of the first grip and the adjustment of the first and second states of the second grip can be performed independently. Therefore, each grip 73 can be positioned in the same position or in different positions. Moreover, the position adjustment of the grips 73 can be performed at any time. That is, one can be adjusted and then the other adjusted, or only one or only the other can be adjusted.

[0038] <Effects of the Embodiment> (1) The training bar 50 allows the position of the grips 63 and 73 to be changed in the direction of extension of the shaft 72. Therefore, the user can efficiently apply load to the muscle groups to be trained. Furthermore, moving the grips 63 and 73 in the direction of extension of the shaft 72 can accommodate physical characteristics, such as having wide or narrow shoulders.

[0039] (2) The training bar 50 can be inserted into the first insertion part S1 by operating the grips 63 and 73 in a direction that moves them away from the floor, that is, in the opposite direction to the direction in which gravity acts. In this state, the grips 63 and 73 can be moved to any position between the ends of the shafts 62 and 72. The training bar 50 can also be inserted into the second insertion part S2 by operating the grips 63 and 73 in a direction that moves them closer to the floor, that is, in the same direction as the direction in which gravity acts. In this state, the grips 63 and 73 can be fixed to any position between the ends of the shafts 62 and 72. In other words, in order for the user to release the fixed position of the grips 63 and 73, it is necessary to lift the grips 63 and 73 in the direction that opposes gravity. For this reason, the training bar 50 makes it easier to prevent the grips 63 and 73 from unintentionally moving to other positions by accidentally making them adjustable.

[0040] (3) The grips 63 and 73 of the training bar 50 are provided independently. This means that the position of each grip 63 and 73 can be adjusted independently. Therefore, the training bar 50 can be further adjusted when training specific muscle groups.

[0041] (4) The position of the grips 63 and 73 on the training bar 50 can be adjusted by inserting the insertion part R into which insertion part S while holding the grips 63 and 73. Therefore, compared to, for example, forming multiple screw holes in the bar body B1 and screwing the grips 63 and 73 into the screw holes at the desired positions, the position of the grips 63 and 73 can be adjusted easily and quickly. Accordingly, the training bar 50 of this embodiment provides a training bar 50 that can be adjusted easily and quickly.

[0042] (5) The dip bar 60 is detachable from the support column 40. Therefore, the user can change the height of the dip bar 60 as desired, making it easier to adjust the training for specific muscle groups. Furthermore, the dip bar 60 can be attached to any exercise equipment 10 that has a similar support column configuration, so the dip bar 60 can be shared. Even if the support column configuration is different, the dip bar 60 of this embodiment can be attached to exercise equipment with a different support column configuration by attaching an attachment to the first support part A1. Therefore, when using the dip bar 60 of this embodiment, it is not necessary to have the entire exercise equipment 10, which reduces the burden on the user and meets the user's needs.

[0043] (6) The user can change the position of the grip 73 by moving it left or right. This allows the user to concentrate the load on a desired area. Furthermore, the left or right movement of the grip 73 can accommodate physical characteristics, such as having wide or narrow shoulders.

[0044] <Example of changes> The above embodiment can be implemented with the following modifications. The above embodiment and the following modifications can be combined with each other to the extent that they do not contradict each other technically.

[0045] The grips 63 and 73 only need to be movable to at least two positions in the extending direction of the shafts 62 and 72. The number of adjustable positions and the range between them can be arbitrarily changed depending on how the second insertion part S2 is formed relative to the first insertion part S1.

[0046] The exercise equipment 10 may be configured with a single vertically erected support column and the training bar 50 of the embodiment positioned on that support column. The training bar 50 may be directly attached to the single vertically erected support column. Alternatively, the training bar 50 may be attached to a rod-shaped member that branches in the front-to-back direction from the single vertically erected support column. For example, a chin-up bar 70 may be supported by a single support column. Also, a dip bar 60 may be supported by two support columns.

[0047] The support column 40 may be fixed by being sandwiched between the floor surface and the ceiling surface opposite the floor surface. In this case, the number of support columns 40 may not be two, but for example, one. The insertion portion S may be a single insertion portion S without being divided into left and right halves. Two grips 63 and 73 may be placed on this single insertion portion S.

[0048] The sliding member T may be a roller bearing or a needle bearing. Each grip 63, 73 does not necessarily have to be able to move independently. For example, each grip 63, 73 may be configured such that their movement relative to each other is a pair of left-right movements, perhaps through a linkage mechanism.

[0049] The dips bar 60 may be directly fixed to the support column 40. The configuration of the chin-up bar 70 can also be applied to exercise equipment 10 that allows for exercise in a hanging position.

[0050] [Note] The technical concepts that can be understood from the above embodiments and alternative examples are described below. (i) An exercise device that allows a user to perform exercises in a hanging position while gripping a grip, comprising a chin-up bar and the grip provided on the chin-up bar, wherein the chin-up bar includes a chin-up bar body and a shaft connected to the chin-up bar body and extending in the left-right direction, the grip includes a sliding member through which the shaft can be inserted and which is slidable in the direction of extension of the shaft, and an insertion part connected to the sliding member and which is slidable in accordance with the movement of the sliding member, the chin-up bar body includes an insertion part into which the insertion part can be inserted, and the insertion part is the same The shaft includes a first insertion portion extending along the extension direction of the shaft and a plurality of second insertion portions integrally formed with the first insertion portion, wherein the plurality of second insertion portions protrude in a direction perpendicular to the extension direction of the first insertion portion and are positioned at predetermined intervals in the extension direction of the first insertion portion, and when the insertion portion is inserted into the first insertion portion, the grip can be moved to any position between the ends of the shaft, and when the insertion portion is inserted into any of the second insertion portions, the grip can be fixed to any position between the ends of the shaft.

[0051] Because each user has different physical characteristics, for example, the training exercise aid disclosed in Japanese Patent Publication No. 8-257164 had to be designed assuming the average physique of the user, making it difficult to perform training tailored to the user's physique. In contrast, according to the above appendix (a), the user can apply load to desired muscle groups by changing the position of the grips in the left-right direction, and by fixing the position of the grips in the left-right direction, they can apply load to those areas intensively according to the user's physical characteristics.
