As shown in Figure 1, Figure 2, and Figure 4:

The bench press chest press trainer of the present invention increases resistance in two different ways.

The base 1 is a tripod structure, that is, it has a ground horizontal support part 11', a vertical support part 12' in the form of an X-frame at the rear connected to the ground horizontal support part 11', and the upper end of the inclined seat support part 13' The vertical support portion 12 ′ is connected, and the lower end is connected to the ground horizontal support portion 11 ′. Such a structure ensures the stability of the entire base 1 .

The seat cushion 3, the back cushion 4 and the head cushion 5 are installed on the seat support part 13', and the part A under the seat cushion 3 is a cushion adjustment structure, which is an existing pneumatic structure and can be adjusted to a suitable exercise position according to the height of different people , the height of the seat cushion 3 can be adjusted according to the height of the user, gently lift the adjustment handle, the built-in air pressure spring will push the seat cushion up, adjust the height to the required height and let go, the built-in torsion spring will The adjusting handle springs back so that the adjusting handle is stuck in the groove of the front adjusting plate and is supported obliquely on the front adjusting plate. The three rollers are attached to the front and rear adjustment plates, and the three-point positioning method ensures a suitable gap for movement, which can be adjusted smoothly without shaking.

The person sits on the seat cushion 3, and the body lies on the back cushion 4 and the head cushion 5 to achieve a comfortable exercise posture.

The left swing frame 9 is hinged on the upright support part 12' of the base 1 by the hinge shaft 91, and the left handle 11 is installed on the lower part of the left swing frame 9,

The right swing frame 10 is hinged on the upright support part 12' of the base 1 by the hinge shaft 101, and the right handle 12 is installed on the lower part of the right swing frame 10,

The outer sides of the middle parts of the left swing frame 9 and the right swing frame 10 are respectively fixed with barbell plate hanging rods 19 , which can be placed on the barbell plate hanging rod 19 according to the user's situation.

The distance between the upper end of the left swing frame 9 and the right swing frame 10 is smaller than the distance between the lower ends, that is, it is designed into a figure-eight shape according to the ergonomic motion trajectory.

As shown in Figure 3:

The two swing frames of the left swing frame 9 and the right swing frame 10 are respectively equipped with adjustment mechanisms. Taking the right swing frame as an example, the adjustment mechanism is: a hollow cylindrical adjustment cylinder 13 is fixed on the lower part of the right swing frame 10, and the adjustment cylinder 13. A circumferential moving groove 130 is opened on the outer wall, and the moving groove 130 extends radially with several locking grooves 131.

The right handle 12 is inserted into the adjusting cylinder 13 through the cylindrical adjusting rod 121 fixed by the connecting plate 120, and a return spring is provided between the adjusting rod 121 and the adjusting cylinder 13 (not shown in the figure, the restoring spring pulls the adjusting rod 121 into the adjusting cylinder 13). Adjustment cylinder 13 ), the clamping block 122 extending axially from the adjustment rod 121 is clamped in the clamping groove 131 . When it is necessary to adjust the position of the right handle 12, pull out the adjusting rod 121, the block 122 leaves the groove 131, rotate the adjusting rod 121, and the block 122 moves in the moving groove 130 to the next corresponding position of the groove 131, Release the adjusting rod 121, under the action of the return spring, the adjusting rod 121 is inserted into the adjusting cylinder 13, and the clamping block 122 is inserted into the clamping slot 131, thereby fixing the right handle 12 again, so that the right handle 12 can be moved and rotated to adjust the front and rear positions , in order to meet the needs of users, the same structure is also applied to the position of the left handle 11 .

The two ends of the upper connecting frame 7 and the lower connecting frame 8 are respectively connected to the vertical support part 12' of the gantry frame 6 and the base 1, so that the gantry frame 6 is connected to the base 1 by the upper connecting frame 7 and the lower connecting frame 8 .

The guide rod 15 is erected in the gantry 6, and the counterweight block 14 is equipped with a guide sleeve and is sleeved on the guide rod 15 to slide between the guide rods 15. The counterweight block 14 is provided with a counterweight latch for adjusting the weight.

One end of the lower wire rope 16 is connected to the counterweight block 14, passes around the fixed pulleys 17 installed in the gantry frame 6 and then extends out of the gantry frame 6, then bypasses the fixed pulley 171 in the middle of the horizontal support portion 11' on the ground, and then winds After passing through the lower pulley 211 of a movable pulley block 21, the other end of the lower wire rope 16 is finally fixed on the horizontal support portion 11' of the ground.

One end of the upper wire rope 20 is fixed on a joint bearing 221 installed on the left swing frame 9, and after bypassing the left fixed pulley 181 installed on the upright support part 12', it bypasses the upper pulley 212 of the movable pulley block 21, and then bypasses the upper pulley 212 of the movable pulley block 21. The right fixed pulley 182 installed on the vertical support part 12 ′, and finally the other end of the upper wire rope 20 is fixed on a joint bearing 222 installed on the right swing frame 10 . The above-mentioned various fixed pulleys are used for the wire rope to go around at each angle change to ensure the smooth movement of the wire rope.

The working principle of the present invention:

The bench press chest press trainer of the present invention increases resistance in two different ways.

The first is:

The weight of the counterweight 14 of the gantry 6 is transmitted through the lower wire rope 16, the movable pulley block 21, and the upper wire rope 20 and is connected to the left swing frame 9 and the right swing frame 10. When the player pushes the left handle 11, the left swing is lifted. When the frame 9 rotates around the hinge shaft 91, pushes the right handle 12 and lifts the right swing frame 10 to rotate around the hinge shaft 101, it needs to overcome the weight of the counterweight 14 and pull up the counterweight 14 to generate a reciprocating motion. To achieve the purpose of exercising the pectoralis major, anterior deltoid, and triceps.

The second is:

The barbell plate hanging rods 19 on the left swing frame 9 and the right swing frame 10 can select barbell plates with different weights according to different force values suitable for users.

The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments, and the same and similar parts between the various embodiments can be referred to each other. The above description of the disclosed embodiments enables any person skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention. Thus, the present invention is not intended to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
