[0050] The description herein is an illustration of the preferred embodiments of the present invention and is not intended to limit the scope of the present invention as described and claimed.

[0051] The fitness equipment including the features of the utility model is as follows Figure 1-16 As shown in Figure 10. Figure 1 The exercise machine 10 is shown in a folded or retracted position to save space when the exercise machine is not in use.

[0052] The exercise machine 10 has a frame assembly 12 , wherein the frame assembly 12 includes a plurality of frame members, wherein the frame members include vertically oriented, spaced apart frame members 14 , 16 .

[0053] The platform 18 includes a carrier 20 and frame members 22, 24, wherein the frame members 22, 24 are rotatably connected to a transversely extending front base frame member 26 (see Figure 1 , Figure 3 , Figure 4 ). Although the utility model can be installed with a platform and can bring desirable results, according to the broadest aspect of the utility model, it is possible to omit the provision of a platform and stabilize the fitness machine by bolting the frame members to the floor or using other stabilization systems.

[0054] like Figure 1 As shown, when not in use, the platform 18 is retained in the retracted position by the cooperation of a spring pin 32 which is retained in a member 34 connected to the vertically oriented, spaced apart frame members 14, 16 and which is normally biased into a channel 36 of a member 38 extending outwardly from the frame members 22, 24 of the platform 18 (see Figure 1 , Figure 3-6 ). This arrangement for maintaining the platform 18 in the retracted position is also employed in the more preferred embodiment of the exercise machine 200, which will be described in detail below.

[0055] By along Figure 1 The spring pin 32 is pulled upward in the direction of the arrow shown, and the spring pin is pulled out of engagement with the corresponding channel 36 of the member 38 to allow the platform 18 to rotate to a horizontal position for use of the fitness machine 10. (See Figure 3-4 ). Specifically, in a preferred embodiment, the platform 20 of the platform is configured to support a work surface 40, on which a person using the machine can sit or lie supinely while exercising. Alternatively, the individual using the machine can be supported directly by the platform 20 without the use of a work surface or other body support structure. The platform 18 with the platform 20 is a desirable feature of the most preferred embodiment of the present invention because a person on the platform, with or without the platform, can apply a downward force to the machine to help stabilize the machine 10 during use. If the platform 18 is not included, it will be necessary to rely on other means to stabilize the machine 10; such as bolting its frame members to its supporting surface.

[0056] Reference Figure 2 , when the work surface is not in use, it can be kept in the storage area 42 provided by the transversely extending front base frame member 26, the side base members 44 and the transversely extending rear base member 46. According to the broadest aspect of the present invention, it is not necessary to provide a storage area 42. In fact, in a more preferred exercise machine 200, no such storage area is included so that the exercise machine structure is more compact.

[0057] like Figure 1-4 As shown, when the fitness machine is not in use, the rotatably mounted fitness arms 48, 50 are maintained in a retracted position. In this retracted position, the arms 48, 50 are preferably located in a vertical plane provided by the vertically oriented spaced apart frame members 14, 16 to provide an ideal compact structure when the fitness machine 10 is not in use.

[0058] Reference Figure 1-3 The fitness arms are held in the retracted position by engagement of pins 52 in U-shaped members 54 (or other similar components) which typically engage openings 56 on the inner surfaces of the fitness arms 48, 50. Figure 7 4. The U-shaped member 54 is held by welding or any other suitable means to the vertically extending frame members 58, 60 of the frame assembly 12 of the exercise machine 10. It should be noted that this arrangement for holding the exercise arms in the retracted position is also employed in the more preferred exercise machine 200 of the present application, which will be described in detail later in this application.

[0059] Reference Figure 4 When the pins 52 (preferably spring pins) are pulled in the direction of the arrows, the pins will disengage from the corresponding openings 56 of the fitness arms 48, 50 to allow the arms to rotate about the axes 49, 51 to the working position, as shown in FIG. Figure 7-9 shown.

[0060] Reference Figure 2 and 5 -7, the fitness machine 10 is preferably provided with a rotatably mounted fitness arm engagement member 62, and is provided with one fitness arm 48, 50. Each fitness arm engagement member 62 is identical and is rotatably mounted about an axis 64 from Figure 3 and Figure 5 The inactive or non-operating position is best shown rotatably mounted to Figure 2 , 4 and Figure 6-84 and 5. The fitness arm engagement position is best shown in FIG. The fitness arms 48, 50 can be axially moved along axes 49, 51, respectively, to allow adjustment of the spacing between each other to accommodate people of different sizes. In a similar manner, the fitness arm engagement member 62 can be axially moved along its corresponding axis 64 to be positioned to align with the fitness arm engagement member to provide its required support function, which will be described in more detail below. The same configuration of rotatably mounted fitness arm engagement members is used in the more preferred fitness machine 200, and the fitness arms and fitness arm engagement members are mounted axially along their corresponding rotational axes, which will be described in detail later in this application.

[0061] The following describes Figure 17-29 In the most preferred embodiment of the present invention shown in FIG. 2 (eg, fitness machine 200), each fitness arm is preferably composed of two parts that can be rotatably mounted relative to each other, one of which preferably includes a telescopic member.

[0062] Reference Figure 5 The locking pin 66 is typically spring loaded into a channel 68 (eg, Figure 6 ) to maintain each exercise arm engagement member in the inoperative position. This position is maintained when the exercise machine 10 is not in use and allows the components of the exercise machine 10 to remain in the desired retracted state. When the exercise arms 48, 50 are rotated downward to overcome the opposing force generated by the stretching of the elastic tension band, the exercise arm engagement member 62 is also maintained in the inoperative position.

[0063] Reference Figure 5 and Figure 6 , when it is necessary to use the fitness machine and provide support for the fitness arms 48, 50 in the desired starting position, such as Figure 5 As shown, each locking pin 66 is pulled outwardly to release the pin from engagement with the corresponding channel 68 and allow the fitness arm engagement member 62 to be moved in a closed position. Figure 6 The locking pin is spring loaded into a corresponding channel (not shown) in the fitness arm engagement member 62 when the fitness arm engagement member is in the working position.

[0064] Reference Figure 6-8 A cushioning member or pad 70 is preferably connected to an upper surface 72 of each exercise arm engagement member 62 when the exercise arm engagement members 62 are in an active position to support the exercise arms 48, 50 to provide a cushioning effect when the rotatable exercise arm moves into engagement with the corresponding exercise arm engagement member.

[0065] Reference Figure 8-11Each exercise arm 48, 50 preferably includes a rotationally adjustable grip 74, 76 at its distal end for engagement by a person during exercise. Figure 8 The handles 74, 76 are shown in a desired orientation. Fig. 9 Shows from Figure 8 The illustrated position shows the handle rotated approximately 90 degrees in a second desired orientation.

[0066] Reference Fig.10 and 11 , a configuration that allows the handle 74 to be rotationally adjusted relative to the exercise arm 48 will be described, it being understood that an identical configuration is provided to allow the handle 76 to be rotationally adjusted relative to the exercise arm 50. The locking pin 78 is typically spring loaded inwardly (i.e., the locking pin 78 is preferably a spring locking pin) to engage within a desired opening 80 of the flange 82 to which the handle 74 is secured. When it is desired to change the position of the handle 74, the spring locking pin 78, which may be spring loaded inwardly, is retracted. Fig.10 The handle 74 is pulled outward in the direction of the arrow shown to allow the handle 74 to rotate to a desired position, such as Fig.11 In this new desired position, the locking pin 78 is spring loaded into the aligned opening 80 in the flange 82 to retain the handle 74 in its new position. As previously described, the handle 76 is connected to its corresponding exercise arm 50 in the same manner. In accordance with the broadest aspects of the present invention, the handle 76 need not be rotatably mounted relative to the exercise arm, or other configurations may be used to provide for rotation of the handle relative to the exercise arm. Figure 17-29 In the preferred embodiment of the exercise machine 200 shown in FIG. 1 , the handle 248 is rotatably mounted to the inner telescopic member 212 of the outer portion 208 of the exercise arm 202, 204 in the same manner.

[0067] Reference Figure 7-9 12, describing the configuration of the fitness machine 10 that allows the use of one or more elastic tension bands 84, which will provide the required resistance when the fitness arms 48, 50 are rotated upward during exercise. In a more preferred embodiment of the utility model, this configuration can also be used Figure 17-29 The exercise machine 200 is shown.

[0068] Combination Figure 13-15 , describes a configuration that allows one or more elastic tension bands 84 to be used in the exercise machine 10, which will provide the desired resistance when the exercise arms 48, 50 are rotated downward during exercise. However, Figure 17-29 A more preferred arrangement for providing such resistance is employed in the exercise machine 200 shown in FIG. 1 , which will be described in detail below.

[0069] Reference Figure 7-9 and Fig.12, the elastic resistance band is preferably configured to be manually usable detachably from the fitness machine 10 of the present invention. For example, the elastic resistance band 84 can be of the type disclosed in U.S. Patent No. 8,657,727; including opposite ends provided by a hook and loop 86 connected to a tether. The subject matter of the 8,657,727 patent is hereby cited in its entirety. However, it should be understood that the present invention is not limited to the use of any particular elastic resistance band; however, the elastic resistance bands available for the present invention are elastic and are preferably of a type that has or can be used for manual exercise, except for the fitness machine 10, 200 of the present invention. However, according to the broadest scope of the present invention, any elastic resistance band within the definition set forth previously in this application can be used in all embodiments of the present invention.

[0070] The fitness machine 10 includes one or more groups of connectors; Figure 7 Six groups of connectors are shown by way of example. Each group of connectors is preferably identical, including a first connector and a second connector that are vertically spaced apart from each other. As shown, the first connector and the second connector of each group of connectors are represented by the same number plus the suffix "a" and "b", respectively. For example, the first connector and the second connector of one of the six groups of connectors are identified as 88a and 88b, respectively.

[0071] In a preferred embodiment of the utility model, the first connectors 88a, 90a, 92a, 94a, 96a and 98a in the six groups of connectors are connected to each fitness arm 48, 50 through a connecting pin or a protrusion and extend outward. In a more preferred embodiment adopted by fitness machine 200 and fitness machine 10, the distal end of each connecting pin has a flange 297 to help maintain the connection between each connecting pin and the connector 100 used to connect the elastic tension band to the connecting pin, which will be described in detail below. The second connectors 88b, 90b, 92b, 94b, 96b, 98b of each group in the six groups of connectors are annular, such as cloth rings or D-rings fixed to the upper surfaces of the frame members 22, 24 of the platform 18. The fitness machine 10 adopts a cloth ring, and the fitness machine 200 adopts a D-ring. However, according to the broadest aspect of the present invention, both the exercise machine 10 and the exercise machine 200 may use the above-described form; other types of connectors may be used in each set as long as the first and second connectors in each set are vertically spaced from each other.

[0072] In all embodiments of the present invention, the number of vertically spaced first connectors and second connectors can be changed. The fitness machine 200 uses only three sets of such connectors.

[0073] Reference Figure 8 and 8A, describes a preferred configuration for connecting the elastic tension band 84 to a set of connectors (including a pin or protrusion (i.e., a first connector 94a) and a mating ring (i.e., a second connector 94b)). Specifically, the elastic tension band 84 is guided through the channel of the mating ring (i.e., the second connector 94b) and engaged between the two ends of the mating ring. The hook and loop 86 that constitute the opposite end of the elastic tension band is preferably connected to the pin or protrusion (i.e., the first connector 94a) through a unique connector 100. This same configuration can be used in Figure 17-29 In the preferred fitness machine 200 shown in FIG. In addition, as previously described, each pin has an enlarged flange 297 at its distal end to prevent the elastic tension band from accidentally separating from the corresponding pin. The use of such a flange is Fig.24 A more preferred fitness machine 200 is shown.

[0074] Specific reference Fig. 8A , and the following will discuss Fig.14 and Fig.16 , the connector 100 includes an open portion 102 in the form of a hook and loop into which the hook and loop 86 is connected. As previously mentioned, other means besides the hook and loop may be used to connect the elastic tension band in the open portion 102. Fig. 8A As shown, the connector 100 also includes an open pin-engaging portion 104, which is configured to be received on a pin or protrusion (i.e., the first connector 94a). A handle or grip 106 is preferably provided or connected to the peripheral wall of the pin-engaging portion of the connector 100 so as to easily and manually insert or remove the connector 100 from the corresponding pin or protruding member as needed. It should be noted that the configuration disclosed in this paragraph can also be used for Figure 17-29 The exercise machine 200 shown in FIG.

[0075] During use of the fitness machine 10, the elastic resistance bands connected to the vertically spaced connectors should be in a stretched state, not a relaxed state. This configuration of the connector 100 with the handle 106 allows each elastic resistance band 84 to be easily manually connected to a corresponding pin, such as 88a-98a, under tension. As previously described, according to the broadest aspect of the present invention, fastening devices other than hooks and loops can be used as part of the elastic resistance bands, and fasteners other than pins 88a-98a can be used on the fitness arms 48, 50. When the fitness arms 48, 50 are rotated upward, the elastic resistance bands 84 will be stretched to provide resistance to the exerciser rotating the fitness arms. The degree or amount of resistance depends on the specific elastic resistance band or bands used in the fitness machine 10, as well as the number of elastic resistance bands used. The configuration herein also applies to Figure 17-29 The exercise machine 200 shown in FIG.

[0076] Reference Figure 13-15, shows a configuration that allows exercise, wherein the fitness arms 48, 50 rotate downward to stretch the elastic tension band 84, thereby providing resistance to the downward rotation of the fitness arms. However, a more preferred configuration is adopted in the fitness machine 200, and will be described in detail below.

[0077] Reference Fig.13 Each of the exercise arms 48, 50 has the same structure as in the previous embodiment of the present invention, preferably including pins 88a-98a as connectors for the elastic tension band 84. The exercise machine 10 includes an upper horizontal frame member 108 to which a connector 110, preferably a spaced annular connector, is connected. Fig.13 As shown, the elastic tension band 84 (only one is shown) passes through the ring (connector 110), and its opposite ends are respectively connected to the pins of the spaced fitness arms 48 and 50. It should be understood that Figure 1-12 The embodiment of the invention shown may also include a ring (connector 110).

[0078] Reference Fig.14 , connect each end of the elastic tension band to the pin in the same manner as described above. Fig.13 The main difference in this embodiment is that each elastic tension band is connected to two exercise arms 48, 50.

[0079] Reference Fig.15 The structure of the fitness equipment 10 is Fig.13 The structure shown is the same as that shown in FIG. 1 ; the only difference is the connection method of the elastic tension band 84 to provide tension or resistance when the fitness arms 48, 50 are rotated downward. The connection system used in this embodiment is the same as that in FIG. Figure 1-12 The connection system used in the illustrated embodiment is similar. Specifically, a separate elastic tension band 84 is connected to each fitness arm 48, 50, each elastic tension band 84 is positioned by a ring (connector 110) connected to the frame member 108, and the opposite end of the elastic tension band is connected to a corresponding pin on one of the fitness arms through a connector 100, and the connection method is similar to that of the embodiment shown. Figure 1-12 The connection method is the same in the embodiments shown and described in FIG. Fig.16 for Fig.15 The enlarged view of the circled area "16" in the figure best illustrates this connection.

[0080] The most preferred embodiment of the fitness machine is Figure 17-29200 is shown in the figure by the reference numeral 200. Many elements of the fitness machine 200 are the same or very similar to corresponding elements in the fitness machine 10, and in some cases, are identified by the same reference numerals as in the fitness machine 10. The structure and function of these common or similar elements will not be repeated herein unless necessary to explain the changes in their structure. For example, the fitness arm is maintained in the upper locking position (U-shaped member 54, pin 52) in the same manner; when necessary, a telescopic stop device (fitness arm engagement member 62) is provided to limit the downward movement of the fitness arm; and at the same time, the platform is mounted to the fitness machine in the same manner, including the same platform structure (platform 18, carrier 20, frame members 22 and 24). In addition, the fitness machine 200 also includes a locking device for locking the platform in the open working position, which will be described in detail below.

[0081] As described in conjunction with the exercise machine 10, when the exercise machine 200 is added to the platform 18, a person on the platform 18, either alone or in conjunction with the workbench 40 or other support member, can provide stabilization to the exercise machine. The same effect can be achieved by using the platform 18 in the exercise machine 200. Another or additional way to stabilize the exercise machine 200 is to bolt or otherwise connect the frame members of the exercise machine 200 to the ground or other supporting surface on which the exercise machine is located, including a vertical wall adjacent to the exercise machine.

[0082] Reference Fig.18 and 21 and Figure 24-29 , discloses a locking device for maintaining the platform 18 in its open working position. Each of the frame members 22, 24 includes a member 282 located on its upper surface and having an opening 284 ( Fig.21 ). Reference Fig.18 , 21 24, the locking pins 286 are preferably spring loaded within locking pin retaining members 288, wherein the locking pin retaining members 288 are included on the upper surface of the support member 290 on the outside of each frame member 22 and 24 adjacent to the platform 18. When the platform 18 is in its open working position, each locking pin retaining member 288 is located adjacent to the corresponding locking member 282 on the upper surface of the frame members 22 and 24 so that each locking pin 286 is inserted into the opening 284 to keep the platform 18 locked in its desired working position.

[0083] Reference Fig.18 , 2124-29, in order to provide a more compact structure than the exercise machine 10, and also to provide a more ideal biomechanical configuration for the movement of the exercise arms 202, 204 in the exercise machine 200, the upright, spaced-apart frame members 201, 203 and the upwardly extending frame members 205, 207 in the exercise machine are inclined toward each other in an upward direction. This more compact configuration results in the spaced-apart exercise arms 202, 204 in the exercise machine 200 being laterally closer than the spaced-apart exercise arms 48, 50 in the exercise machine 10. In fact, as Fig.17 As shown, the outer ends of the handles or grips 248 of the exercise arms 202, 204 are only a short distance apart in the highest rotational position of the exercise machine. Fig.18 As shown, when the fitness arms 202, 204 are in a generally horizontal position, the outer ends of the handles 248 are laterally spaced further apart from each other than when in the highest position. However, due to the unique structure of the fitness arms 202, 204, the fitness arms may still be too close together to accommodate people of various sizes, as will be described in detail below.

[0084] Reference Fig.18 , 21 24-29, the shaft 49 in the fitness machine 200 is connected to the upright frame member 201 and the upwardly extending frame member 205, and is located between the upright frame member 201 and the upwardly extending frame member 205, and is approximately 90 degrees to the frame members. Therefore, unlike the shaft 49 in the fitness machine 10, the shaft 49 in the fitness machine 200 is at a certain angle relative to the surface supporting the fitness machine 200, and is used to rotatably mount the fitness arm 202 for upward and downward rotational movement. The same configuration is used for the shaft 51, which is connected to the upright frame member 203 and the upwardly extending frame member 207. The shaft 51 rotatably supports the fitness arm 204 at a position laterally spaced from the fitness arm 202. In the most preferred embodiment, unlike the fitness machine 10, the rotational movement of the fitness arms 202, 204 about the shafts 49, 51 will be limited, that is, the fitness arms do not provide axial movement along the shafts 49, 51.

[0085] Because the axes 49, 51 are inclined, the grips 248 grasped by the exerciser move inwardly toward each other as the exercise arms 202, 204 rotate upward during exercise, and the exercise arms move outwardly away from each other as the grips move downward. This is a very ideal biomechanical configuration for exercise; it follows the normal movement of the exerciser's arms more naturally than the arrangement employed in the exercise machine 10. In the exercise machine 10, the grips 74, 76 of the exercise arms 48, 50 maintain the same lateral spacing from each other as they move upward and downward about their respective axes 49, 51.

[0086] Reference Fig.18 , 2124-29, unlike exercise machine 10, exercise machine 200 includes laterally spaced apart side arms 250, 252 that may be rotatably mounted to inclined frame members 201, 203 to provide unique functionality as described in detail below.

[0087] Reference Figure 26-27 , the fitness arms 202, 204 in the fitness machine 200 include inner and outer portions 206, 208, respectively, which are pivotally connected together by a hinge connection 214. Fig.18 , 20 , 21 and 23. The hinge connection 214 will be described in detail below.

[0088] Reference Figure 26-28 As shown, the outer portion 208 of each exercise arm 202, 204 includes laterally spaced pins (first connectors 292a, 294a and 296a) extending laterally therefrom, and includes an enlarged flange 297 at its outer end. Spaced D-rings (second connectors 292b, 294b and 296b) are connected to the frame members 22, 24 of the platform 18. The spaced pins and spaced D-rings provide three sets of connectors (292a and 294b, 294a and 294b, 296a and 296b), respectively. The number of sets can be varied as desired; the illustrated exercise machine 10 has six sets of connectors. In practice, only one set of connectors can be used if desired. The number of connector groups and the specific structure of the connectors do not constitute a limitation on the broadest aspects of the present invention; the only requirement is that each group of connectors is oriented and configured to retain more than one elastic tension band, such as 298, 300, in the fitness machine so as to be stretched when the fitness arms 202, 204 are rotated upward, such as Fig.26 shown.

[0089] Reference Fig.26 , a preferred manner of connecting one or more elastic tension bands 298, 300 to the complete connector is shown in dotted lines. Specifically, the ends of the two elastic tension bands 298, 300 are connected to corresponding D-rings, such as the second connector 292b or other connectors, by hooks and loops or other suitable connectors connected to their free ends. Then, the elastic tension bands 298, 300 are stretched and inserted into corresponding pins, such as the first connector 292a, so as to be kept under tension before being rotated upward during exercise. An enlarged flange 297 is provided at the far end of each pin to prevent the elastic tension band connected to the corresponding pin from accidentally slipping off or accidentally separating from the corresponding pin. Before exercising, the fitness arms 202, 204 are kept in the desired stop position by engaging with the cushioning pad 70 on the upper surface 72 of the fitness arm engagement member 62.

[0090] As described above, although connecting the elastic tension band 298, 300 to a set of pins and D-rings is the preferred connection configuration used in the fitness machine 200, according to the broadest aspect of the present invention, other configurations can also be used to connect the elastic tension band 298, 300 to the fitness arms 202, 204, and one or more fitness machine frame members located below the fitness arm rotation axes 49, 51, respectively. For example, but not limited to this, the elastic tension band 298, 300 can be connected to the D-rings and pins through the connector 100 in the same manner as the fitness machine 10. In addition, the design length of the elastic tension band can allow its opposite ends to be connected to one or more sets of D-rings and pins through suitable connectors. For example, the opposite ends of the elastic tension band can include hooks and loops or other suitable connectors to connect to the D-rings, such as the second connector 292b and the corresponding pins (first connector 292a) through the connector 100 used in the fitness machine 10.

[0091] Reference Fig.24 and 25 , the outer portion 208 of the fitness arms 202, 204 includes an outer member 210 and an inner telescopic member 212, respectively, and the exercise handle 248 is rotatably mounted at the distal end of the inner telescopic member 212. A locking pin 213, preferably a spring locking pin, is fixed in an opening through the top wall of each outer member 210, usually biased inwardly. The inner telescopic member 212 includes a plurality of axially spaced holes 215 ( Fig.25 ), which are aligned with locking pins 213, so that when the inner telescopic member 212 is in a desired position relative to its corresponding outer member 210, the locking pins engage with one of the axially spaced openings 215 to maintain the inner telescopic member 212 in a locked state to prevent it from moving relative to the outer member 210. The outer portions 208 of the exercise arms 202, 204 are arranged to be telescopic, thereby allowing the length of each exercise arm to be adjusted to accommodate people of different body types and / or allowing individuals to adjust the length of the exercise arms to perform different exercises. Fig.24 and Fig.25 Different telescopic positions of the inner telescopic member 212 in the outer member 210 are shown respectively.

[0092] like Fig. 20 As shown, the plate-like extensions 216, 218 of the inner portion 206 and the outer portion 208 respectively have annular ends rotatably mounted on a shaft (not shown). It should be noted that the outer member 210 of the outer portion 208 of each fitness arm 202, 204 is a component rotatably mounted on a shaft, which rotatably connects the outer and inner portions 206, 208 of the fitness arm together. Still referring to Fig. 20, the plate-like extension 216 includes spaced annular ends 220, 222, and the plate-like extension 218 includes spaced annular ends 224, 226. The annular ends 220, 222 are staggered with the annular ends 224, 226 so that the passages through the annular ends 220, 222, 224 and 226 are vertically aligned so as to be rotatably mounted on an axle (not shown). This arrangement is to rotatably connect the inner portion 206 and the outer portion 208 of each fitness arm 202, 204 together.

[0093] Reference Fig.18 and Fig. 20 The U-shaped member 228 for maintaining the inner portion 206 and the outer portion 208 of each fitness arm 202, 204 in a desired relative rotational direction includes a base portion 230 and horizontally extending vertical spacing adjustment plates 232, 234 ( Fig. 20 ), the base portion and the adjustment plate are used to accommodate the rotatably connected ends of the inner and outer portions of each fitness arm respectively. These adjustment plates 232, 234 include a series of arc-shaped spaced holes; each arc-shaped spaced hole 236 on the adjustment plate 232 is vertically aligned with a corresponding hole 238 on the adjustment plate 234. Vertically aligned openings (not shown) are provided at the upper and lower walls 242, 244 of the inner and outer portions 206, 208 of the fitness arm between the adjustment plates 232, 234, and the locking pin 246 can pass through these openings.

[0094] like Fig. 20 As shown, the locking pin 246 is used to maintain the inner portion 206 and the outer portion 208 of the fitness arm 202, 204 in the desired direction. For example, but not limited to this, Fig.21 and Fig.23 As shown, the inner portion 206 and the outer portion 208 of each exercise arm are oriented 90 degrees to each other. In this orientation, the locking pin 246 passes through the vertically aligned openings 236, 238 on the adjustment plates 232, 234, respectively, and through the aligned openings (not shown) on the upper and lower walls of the outer portion 208.

[0095] The inner and outer portions 206 and 208 of the exercise arms 202 and 204 may be held at any desired angular position to facilitate exercise (see, e.g., Fig. 27). By making the above adjustments between the inner portion 206 and the outer portion 208 of the exercise arms 202, 204, people of different body types can easily perform multiple exercises between the exercise arms. In addition, individuals may wish to change the spacing between the handles 248 of the exercise arms 202, 204 to perform different exercises. These handles 248 can have the same structure as the rotatable adjustable grips 74, 76 used in the exercise machine 10; and they can be mounted in the same manner as the exercise machine 10 for adjustment. For the sake of brevity, this mounting method of the handles 248 will not be described in detail herein.

[0096] If desired, the locking pins 246 that hold the inner and outer portions 206, 208 at desired angular positions relative to each other can be removed to allow continued rotational movement of the inner and outer portions relative to each other by rotating the exercise arms 202, 204 about their respective axes 49, 51 during exercise.

[0097] Reference Figure 17-19 , 21, 22 and 24-26, the fitness machine 200 also includes side arms 250, 252, which are rotatably mounted on the outer surfaces of the spaced-apart upright frame members 201, 203, respectively, to provide functions that will be described in detail below.

[0098] Each side arm 250, 252 is identical in structure, and includes an outer portion 254 and an inner telescoping portion 256, respectively. The inner telescoping portion 256 can be telescoped within the outer portion 254 to linearly adjust the length of the side arm 250, 252, and the outer portion 254 is rotatably mounted to the spaced upright frame members 201, 203, as will be described in detail below. The swivel mount of the outer portion 254 of the side arm 250 to the frame member 201 is the same as the swivel mount of the outer portion 254 of the side arm 252 to the frame member 203. Therefore, the swivel mount of the outer portion 254 of the side arm 252 will be described in detail; it should be understood that the outer portion 254 of the side arm 250 is also rotatably mounted in the same manner.

[0099] Reference Fig.19 and 22 The U-shaped mounting member 258 includes a base 260, which is fixed to the upright frame member 203 by welding, bolts or any other suitable means. The U-shaped mounting member 258 includes laterally spaced adjustment plates 262 extending outward from the base 260; each adjustment plate includes arc-shaped spaced openings 264 adjacent to the outer edge of the adjustment plate for rotatably adjusting the direction of the side arms 250, 252. The laterally spaced adjustment plates 262 also include axially aligned openings 272 (such as Fig.19 as shown), to accommodate the shaft (as Fig. 22273 in the figure) so as to rotatably accommodate the proximal end of the outer portion 254 thereon. Specifically, the radially opposite side walls 266, 268 of the outer portion 254 include axially aligned channels 270 therein (only as shown in FIG. Fig.19 272 in the spaced adjustment plates 262 (shown only in FIG. Fig.19 As shown) axially aligned. Fig.19 and Fig. 22 As shown, the shaft 273 passes through the channels 270 and 272 to rotatably support the outer portion 254. According to the broadest aspect of the present invention, in addition to using the U-shaped mounting member 258, other configurations can be used to rotatably mount the side arms 250, 252 to the spaced apart upright frame members 201, 203; the specific configuration does not constitute a limitation of the broadest aspect of the present invention.

[0100] Radially opposed sidewalls 266, 268 of outer portion 254 also include a second set of axially aligned passages (not shown) spaced apart from axially aligned passages 270. The linear distance between passages 270 and the second set of passages is approximately the same as the radial distance between passages 272 and arcuately spaced apertures 264 in adjustment plate 262.

[0101] like Fig.19 and Fig. 22 As shown, the locking pin 274 is used to lock the side arms 250, 252 in a desired rotational position. Fig.19 In the embodiment of the present invention, the side arm 252 is locked in the Fig.18 In this position, the locking pin 274 passes through the lowest point of the arc-shaped spaced-apart openings 264 on the adjustment plate 262 and through the aligned, diametrically opposed openings (not shown) on the diametrically opposed side walls 266, 268 of the outer portion 254.

[0102] Reference Fig. 22 , the side arm 252 is locked to Fig.21 In this position, the locking pin 274 passes through the uppermost end of the arc-shaped spaced-apart openings 264 on the adjustment plate 262 and through aligned, diametrically opposed openings (not shown) on the diametrically opposed side walls 266, 268 of the outer portion 254.

[0103] The side arms 250, 252 can be held in a number of different rotational positions, depending on the number of arcuately spaced openings 264 provided in the adjustment plate 262. For example, note that Fig.18 , 21 , 24, 25, 28 and 29, the side arms 250, 252 have different locked rotation positions.

[0104] In addition, the side arms 250, 252 have an outer portion 254 and an inner telescopic portion 256, making them adjustable in length, which is ideal for providing different exercises and connecting elastic tension bands to the fitness arms 202, 204 (described in detail below), which will be described in detail below.

[0105] like Fig.24 and Fig.25 As shown, in a preferred embodiment of the present invention, the inner telescopic portion 256 of the side arms 250, 252 is provided with a third connecting member 276 at its distal end, and the elastic tension band can be connected to these connecting members (see Fig.28 and Fig.29 ). In the illustrated embodiment, the third connector 276 is in the form of a D-ring. However, within the broadest scope of the present invention, the connector can have a variety of designs; partly depending on how the elastic tension band is connected to the fitness machine 200.

[0106] Reference Fig.29 , by way of example only, an exercise machine is shown that uses elastic resistance bands 278, 280 (shown in phantom for clarity) in an exercise independent of the exercise arms 202, 204. These elastic resistance bands 278, 280 may be provided with a hook and loop at one end thereof to connect the elastic resistance bands to a D-ring or any other acceptable third connector 276. The opposite end of the elastic resistance bands 278, 280 may include a handle or other gripping device to facilitate the individual to perform the desired exercise, such as a fly or other pulling exercise.

[0107] Reference Fig.28 , another desirable advantage of the exercise arms 202, 204 is shown. In this configuration, the exercise arms 202, 204 are initially supported by the exercise arm engagement members 62 prior to attaching the elastic tension bands 298, 300 to the exercise arms. Thereafter, the exercise arm engagement members may be rotated to an inactive position so as not to impede downward movement of the exercise arms 202, 204 during a downward push-pull exercise.

[0108] Still refer to Fig.28 , the elastic tension bands 298, 300 shown in dotted lines are connected to the D-rings or other suitable third connectors 276 located at the distal ends of the inner telescopic portions 256 of the side arms 250, 252. When a D-ring or other annular connector is used, the distal ends of one or more elastic tension bands, such as 298, 300, can be connected to the D-rings or other annular connectors by hooks and loops or other suitable connectors in the same manner as the elastic tension bands 298, 300 are connected to the D-rings (second connectors 292b, 294b, 296b), wherein the D-rings are connected to the frame members 22, 24 of the platform 18. Fig.26As shown, after the distal end of the elastic tension band is connected to the D-ring (third connecting member 276), the elastic tension band is stretched and inserted into the pin, such as the first connecting member 292a, 294a and / or 296a, and its insertion method is the same as the way the elastic tension band 298, 300 is connected to the pin, so as to perform upward pull and push exercises. Although this is a preferred embodiment of connecting the elastic tension band to the D-ring (third connecting member 276) and the pin, respectively, according to the broadest aspect of the utility model, other connection configurations can also be adopted. For example, one or more elastic tension bands can be looped through the D-ring (third connecting member 276), and their free distal ends can be connected to the pin (first connecting member 292a, 294a and / or 296a) through a suitable connector, for example, the connector 100 is selected in the fitness device 10. In the broadest aspect of the utility model, any suitable connection device can be used as long as the device allows the elastic tension band to be stretched during the downward rotation of the fitness arms 202, 204. As previously described, the provision of an enlarged flange 297 at its distal end prevents the elastic tension band from accidentally separating from these pins.

[0109] The initial connection of the elastic tension band 298, 230 to the D-ring (third connector 276) and the pin (e.g., first connector 292a) is performed with the elastic tension band in a relaxed, non-tensioned state. In order to raise the exercise arm 202, 204 to the desired position for performing a downward pull and push exercise under the resistance of the stretched elastic band 290, 300, the inner telescoping portion 256 of each side arm 250, 252 is moved outward. This will first eliminate any slack in the connected elastic tension band and then rotate the exercise arm 202, 204 to the upward position with the handle 248 located above the rotation axis 49, 51 of the exercise arm. In this orientation, the weight of the exercise arm will keep the elastic tension band taut and it is possible to stretch the elastic tension band to a certain extent before use.

[0110] Reference Fig.28 , with dashed lines showing an individual pushing and pulling the exercise arms 202, 204 on a downward rotational path against the resistance provided by one or more elastic tension bands 298, 300 connected to the third connector 276 of the side arms 250, 252 and connected to the exercise arms 202, 204 via mounting pins (first connectors 292a, 294a and / or 296a) connected to the exercise arms. It should be emphasized that, in accordance with the broadest aspects of the present invention, any suitable configuration may be provided to connect the elastic tension bands 298, 300 to the side arms 250, 252 and the exercise arms 202, 204, including but not limited to the manner in which the one or more elastic tension bands are connected or can be connected to the platform 18 and exercise arms 48, 50 in the exercise machine 10, as previously described in this application. For the sake of brevity, this will not be described in detail here.

[0111] The above description is a preferred embodiment of the fitness machine. However, many modifications can be made within the scope of the present invention. For example, although Figure 1-12 Shown in the fitness machine 10 of illustration are six groups of connectors, allow to use up to six elastic tension bands separately, but any required number of groups can be used in this fitness machine.In fact, in the fitness machine 200, use three groups of such connectors.

[0112] Likewise, in accordance with the broadest aspects of the present invention, any desired system may be provided for connecting one or more elastic resistance bands within the fitness machine 10 or 200, as long as the system allows the elastic resistance bands to be stretched during exercise, thereby providing a reactive tension when the fitness arms rotate upward or downward during exercise.

[0113] As mentioned above, the elastic tension band used according to the broadest aspect of the present invention does not need to include a hook and loop used as a connector. However, hook and loop are commonly used on elastic tension bands and are the preferred connection structure.

[0114] Furthermore, while conventional elastic resistance bands may be used in the preferred systems of exercise machines 10 and 200 to provide the desired reactive tension during exercise, within the broadest scope of the present invention, a specially designed elastic resistance band is provided having a length that allows one of the opposite ends to be connected to an exercise arm and the other end of the opposite end to be connected to vertically spaced connectors above and / or below the axis of rotation of the exercise arm.

[0115] In the most preferred embodiment of the present invention, the elastic resistance band used can also be used independently of the fitness machine 10 and 200, and thus has the same or similar length as a conventional elastic resistance band. The elastic resistance band is substantially folded so that its distal end can be connected to one of a set of spaced apart connectors and its central region extends through or around another spaced apart connector in the set. This configuration allows the fitness machine 10 and 200 to be used with an elastic resistance band having the same or similar length as a conventional elastic resistance band that has been used, and can be used independently of the fitness machine 10 and 200.

[0116] Although the present invention has been described in conjunction with the preferred embodiments of the present invention, those skilled in the art will appreciate that other additions, modifications, substitutions and deletions not specifically described may be made to the present invention without departing from the spirit and scope of the present invention as defined in the appended claims.
