As a result, a large number of fitness and shaping products have emerged in the market. Fitness products are divided into aerobic and anaerobic exercise, and also into commercial and home types. Commercial fitness equipment focuses on one machine for one purpose, emphasizing force lines and trajectory; while home fitness equipment emphasizes multi-functionality, using the combination of components to achieve multiple uses. Taking an anaerobic home fitness machine as an example, based on a full-frame squat and bench press rack, it adds functions such as a pull-up bar, parallel bar, and Smith machine with a fixed trajectory, and adds weight blocks and a traction distribution system, which can realize mechanical movements such as flyes, lat pulldowns, butterfly chest presses, chest presses, and seated rows.
[0003] However, in order to maximize the training functions, traditional modular home fitness equipment adds a training device for each new function. This often results in some problems being overlooked, such as overlapping tracks and uneven operation. As a result, the product becomes increasingly heavy, the production cost becomes increasingly high, and the operating space becomes increasingly cramped. Utility Model Content

[0043] like Figure 1-4 As shown, a top-mounted seated chest press device includes a cross beam 21 and a first guide rail 901 and a second guide rail 902 located at the top of the fitness device frame as a longitudinal beam. The two ends of the cross beam 21 are respectively provided with linear bearings 211 and are mounted on the first guide rail 901 and the second guide rail 902 in a relatively movable manner through the linear bearings 211. The cross beam 21 is provided with two swing arm bearings 212, and chest press swing arms 22 are respectively connected to the swing arm bearings 212 below the cross beam 21.
[0044] The fitness equipment frame is a home-use nine-in-one multi-purpose fitness equipment frame, equipped with a first Smith slide rail 91, a second Smith slide rail 92, a first rear frame 93, a second rear frame 94, a first middle frame 95, and a second middle frame 96 that are parallel to each other. The first middle frame 95 is located between the first Smith slide rail 91 and the first rear frame 93, and the second middle frame 96 is located between the second Smith slide rail 92 and the second rear frame 94. The tops of the first Smith slide rail 91 and the second Smith slide rail 92 are connected by a front crossbar 971, and the bottoms of the first rear frame 93 and the second rear frame 94 are connected by a rear bottom crossbar 972.

The upper part of the second rear frame 94 is connected by the rear middle cross frame 973; the bottom of the first middle frame 95 and the bottom of the first Smith slide rail 91 and the first rear frame 93 are respectively connected by the first side frame 981 and the second side frame 982; the bottom of the second middle frame 96 and the bottom of the second Smith slide rail 92 and the second rear frame 94 are respectively connected by the third side frame 983 and the fourth side frame 984; the top of the first middle frame 95 is connected to the upper part of the first rear frame 93 by the first side connecting frame 991; the top of the second middle frame 96 is connected to the upper part of the second rear frame 94 by the second side connecting frame 992.
[0045] The rear crossbeam 973 is located below the first side connecting frame 991 and the second side connecting frame 992.
[0046] The top of the first Smith slide rail 91 and the top of the first rear frame 93 are connected by a first guide rail 901, and the top of the second Smith slide rail 92 and the top of the second rear frame 94 are connected by a second guide rail 902.
[0047] The top of the chest-clamping and chest-pushing swing arm 22 is also provided with a swing arm wheel 23. The swing arm wheel 23 is provided with a steel wire rope 8 arranged around the outer periphery of the swing arm wheel 23. One end of the steel wire rope 8 is fixed on the swing arm wheel 23, and the other end of the steel wire rope 8 is connected to the counterweight 99 after turning around the outer periphery of the swing arm wheel 23 and passing through the steering pulley group 24.
[0048] The steering pulley assembly 24 is located below the linear bearings 211 at both ends of the cross beam 21.
[0049] The wire rope 8 is connected to the counterweight 99 after passing through the steering pulley group 24 and then the compensating pulley group 25.
[0050] The compensating pulley assembly 25 includes a first driven pulley 251, a compensating pulley 252, and a second driven pulley 253. The wire rope 8 is turned by the first driven pulley 251 to the compensating pulley 252, and after being turned by the compensating pulley 252, it is connected to the counterweight 99 via the second driven pulley 253.
[0051] The swing arm wheel 23 is also provided with an opening and closing pin 26.
[0052] The chest-clamping and chest-pushing swing arm 22 includes a swing arm action rod 221 for user operation, a swing arm connecting rod 222, and a swing arm force-bearing rod 223 connected to the swing arm bearing 212. The swing arm action rod 221 and the swing arm force-bearing rod 223 are connected through the swing arm connecting rod 222.
[0053] The two ends of the swing arm connecting rod 222 are respectively connected to the swing arm action rod 221 and the swing arm force rod 223 through the arc connecting section 224.
[0054] The bottom end of the swing arm connecting rod 222 and the swing arm force rod 223 is also provided with a chest-pushing forward bearing 27.
[0055] The bottom end of the swing arm action rod 221 is also provided with a seated chest push handle 28.
[0056] According to this application, a top-mounted seated chest press device uses guide rails instead of longitudinal beams, achieving multiple uses for the component. In a preferred embodiment, the first guide rail 901 and the second guide rail 902 are optical axis guide rails.
[0057] The chest-clamping and chest-pushing swing arms 22 are respectively connected to the swing arm bearing 212 below the cross beam 21. The top of the shaft end where the chest-clamping and chest-pushing swing arms 22 are connected to the swing arm bearing 212 can be provided with a detachable axial limiting device to prevent the chest-clamping and chest-pushing swing arms 22 from falling off, such as a limiting shim fixed to the top of the shaft end by screws and covering the inner ring of the bearing, a thrust bearing device, etc.
[0058] The chest-clamping and chest-pushing arm 22 can function as both a chest-clamping arm and a chest-pushing arm. Its function is to release the torque of the arm wheel, so that the force of the seated chest-clamping and chest-pushing movements is consistent.
[0059] The swing arm wheel generates rotational torque, with the steel cable pulling in opposite directions from both sides. The compensating pulley utilizes the principle of a pulley that pulls in the opposite direction with increased effort; when the steel cable passes through the compensating pulley, the reverse pulling force is doubled, and the stroke of the counterweight is also doubled, thus increasing the torque of the swing arm wheel. The driven pulleys (first driven pulley and second driven pulley) do not generate longitudinal traction force when the steel cable passes through; their function is to redirect the steel cable and provide lateral traction force to the compensating pulleys.
[0060] The opening and closing pin 26 functions as a mode switch for chest clamping and chest pushing exercises. When the opening and closing pin 26 is inserted into the swing arm wheel 23 and the cross beam 21, the swing arm wheel 23 cannot rotate relative to the cross beam 21; removing the opening and closing pin 26 allows the opposite to occur.
[0061] The chest-pushing forward bearing 27 does not function during seated chest clamping, but generates traction force during chest pushing. A steel wire rope 8 is connected to the outer wall of the chest-pushing forward bearing 27 and is connected to the counterweight 99 through a steering wheel assembly. During chest pushing, the cross beam 21 moves along the first guide rail 901 and the second guide rail 902, and the counterweight 99 provides traction force to the chest clamping and pushing arm 22 through the chest-pushing forward bearing 27.
[0062] Except for the specific structures specifically pointed out in the embodiments of this application, the specific structures of other parts, including the connection with the fitness equipment frame and the motion traction method, can all adopt existing fitness equipment technology, and will not be described again in this application. It should be understood that the steel wire ropes described in different parts of this application are all steel wire ropes in the traction system, and can be multiple or discontinuous steel wire ropes, set according to actual traction needs.
[0063] The top-mounted seated chest press machine of this application has a smoother running trajectory compared to previous products. It utilizes the traction force distribution system, which consists of a weight plate 99 and a steel wire rope 8, set on the frame of the fitness machine, to provide traction force in two directions. In the seated chest press movement, it utilizes the lateral traction force, while in the seated chest push movement, it utilizes the longitudinal traction force.
[0064] Traditional seated chest press and push-up machines utilize traction in one direction, and torque distribution uses the lever principle. In the seated chest press motion, the trajectory is curved.
[0065] According to this application, the top-mounted seated chest press device utilizes a cross-slide structure and linear bearings for the chest press motion, resulting in a straight trajectory that is more ergonomic. Furthermore, the guide rail replaces the longitudinal beam, reducing structural weight. The top-mounted design frees up space below, providing installation options for other exercise equipment.
[0066] The present invention has been described in detail above. Specific examples have been used to illustrate the principle and implementation of the present invention. The description of the above embodiments is only for the purpose of helping to understand the method and core idea of the present invention. At the same time, for those skilled in the art, there will be changes in the specific implementation and application scope based on the idea of the present invention. Therefore, the content of this specification should not be construed as a limitation of the present invention.
[0067] Through the above description of the embodiments, those skilled in the art can clearly understand that this utility model is implementable. Of course, the situations listed above are merely examples, and this utility model is not limited thereto. Those skilled in the art should understand that other modifications or simplifications of the technical solutions of this utility model can be appropriately applied to this utility model and should be included within the scope of this utility model.
