Description

Technical Field

[0001] The present application belongs to the technical field of fitness equipment, and in particular to a chest press trainer. Background Art

[0002] With the popularization of fitness awareness, fitness people have higher and higher requirements for training equipment. When using counterweights as a resistance source, it is necessary to manually increase or decrease the counterweights to increase the resistance.

[0003] In the prior art, a chest press trainer usually includes a main frame, two swing arms and a counterweight. The two swing arms are rotatably mounted on the main frame, and one end of the swing arm away from the main frame is used to place the counterweight. The trainee pushes the swing arm to swing away from the main frame, thereby achieving the purpose of training the chest. In the process of the swing arm moving away from the main frame, the resistance increases according to the increase of the force arm.

[0004] However, when the center of mass of the counterweight on the swing arm moves to be flush with the connection point of the swing arm and the main frame, the resistance reaches a peak value. Continued movement of the swing arm will reduce the resistance arm, thereby reducing the resistance, which cannot meet the trainee's need to continuously increase the resistance during training.

[0067] Reference Figure 1 In some embodiments, the swing assembly 300 includes two swing arms and two armrests. The two swing arms are respectively rotatably arranged at one end of the two support frames 201 away from the base frame 100.

[0069] Reference Figure 3 In some embodiments, the transmission assembly 400 is rotatably disposed on one side of the support frame 201 close to the swing arm, and the transmission assembly 400 is rotatably connected to the swing arm. The transmission assembly 400 includes a steering member 402, a connecting member 403 and a transmission member 401; wherein the connecting member 403 is a rod-shaped member, one end of the connecting member 403 is rotatably connected to the steering member 402, and the other end is rotatably connected to the adjusting assembly 500; the transmission member 401 is a rod-shaped member, one end of the transmission member 401 is rotatably connected to the steering member 402, and the other end is rotatably disposed on the swing arm.

[0070] Reference Figure 3 and Figure 5 In some embodiments, the steering member 402 includes a base plate, a first turning point, a second turning point and a third turning point, and the first turning point, the second turning point and the third turning point are arranged on the base plate, wherein the first turning point is used for rotationally connecting with the support frame 201, the second turning point is used for rotationally connecting with the connecting member 403, and the third turning point is used for rotationally connecting with the transmission member 401.

[0071] A first distance is set between the first turning point and the second turning point; a second distance is set between the second turning point and the third turning point; a third distance is set between the first turning point and the third turning point; the first distance, the second distance and the third distance are equal, so that the first turning point, the second turning point and the third turning point are arranged on the steering member 402 according to the three corner points of an equilateral triangle, thereby increasing the range of motion of the second turning point and the third turning point when they rotate around the first turning point, and avoiding instability or jamming when the base plate rotates.

[0072] Reference Figure 3 and Figure 4In some embodiments, when the transmission member 401 does not pull the steering member 402, the distance from the second turning point to the support frame 201 is not less than the distance from the third turning point to the support frame 201, so that when the transmission member 401 pulls the second turning point in the direction away from the support frame 201, the steering member 402 immediately pulls the adjustment assembly 500 and the resistance member 600 through the third turning point and the connecting member 403 to move in the direction away from the horizontal plane, thereby improving the response speed of the resistance member 600 to the movement of the transmission member 401; increasing the rotation stroke of the transmission member 401 around the first turning point, thereby supporting the trainee to perform larger training movements through the transmission member 401.

[0073] It should be noted that, in some embodiments, when the transmission member 401 does not pull the steering member 402, the distance from the second turning point to the main frame is not less than the distance from the third turning point to the main frame, and the second turning point is used to rotate with the transmission member 401, and the third turning point is used to rotate with the connecting member 403, so that when the transmission member 401 pulls the third turning point in the direction away from the main frame, the connecting member 403 needs to wait for the second turning point to rotate around the first turning point to the initial position of the third turning point, and then pull the resistance member 600 to move in the direction away from the horizontal plane, thereby reducing the response speed of the resistance member 600 to the movement of the transmission member 401 and shortening the rotation stroke of the transmission member 401 around the first turning point, so as to be suitable for training when the trainee uses a heavy weight block.

[0074] Reference Figures 1 to 3 In some embodiments, the steering member 402 is also provided with an avoidance opening, which is provided on the bottom plate and is located between the second turning point and the third turning point, so as to increase the range of motion between the transmission member 401 and the connecting member 403, thereby avoiding friction and collision between the transmission member 401 and the connecting member 403, which may cause the steering member 402 to rotate unsmoothly.

[0075] Reference Figures 1 to 4 In some embodiments, the adjustment component 500 includes a rotating member 501 and an adjusting member 502; one end of the rotating member 501 is rotatably disposed on the second stabilizing member 203, and the other end is rotatably connected to the resistance member 600, and the middle part between the two ends of the rotating member 501 is used for rotatably connecting with the connecting member 403, so that the swinging component 300 can pull the rotating member 501 and the resistance member 600 to rotate relative to the supporting component 200 through the transmission component 400.

[0076] One end of the resistance member 600 is rotatably connected to the rotating member 501, and the other end is provided with an extension rod, which is used to place a counterweight.

[0077] One end of the adjusting member 502 is rotatably disposed on the second stabilizing member 203, and the connecting pivot point of the adjusting member 502 and the second stabilizing member 203 is located on the side of the connecting pivot point of the rotating member 501 and the second stabilizing member 203 away from the base frame 100, and the other end of the adjusting member 502 is rotatably disposed between the two ends of the resistance member 600; the rotating member 501 and the adjusting member 502 are actually arranged in parallel, wherein the adjusting member 502 is used to push the resistance member 600 to rotate relative to the rotating member 501 when the swinging assembly 300 drives the resistance member 600 to move in a direction away from the supporting assembly 200, thereby increasing the angle between the rotating member 501 and the resistance member 600, so that the resistance to the swinging assembly 300 continues to increase.

[0078] Reference Figure 1 In some embodiments, a limit member 700 is further fixed on the base frame 100. When the transmission assembly 400 does not pull the adjustment assembly 500, the adjustment assembly 500 and the resistance member 600 are in a naturally drooping state. Since the resistance member 600 is used to place the load and is connected to one end of the adjustment assembly 500, the connection between the adjustment assembly 500 and the support assembly 200 will be damaged due to excessive stress under the action of gravity. By making the limit member 700 abut against the connection between the resistance member 600 and the adjustment assembly 500, the gravity of the adjustment assembly 500 away from one end of the support assembly 200 is borne, preventing the resistance member 600 from driving the adjustment assembly 500 to continue to move toward the base frame 100 in the natural drooping state, thereby avoiding the structure of the adjustment assembly 500 from being damaged.

[0079] Reference Figure 1 In some embodiments, a placement rack 800 is further provided on the support frame 201, and the placement rack 800 is used to place idle counterweight blocks to facilitate trainees to use the counterweight blocks.

[0080] It should be noted that the chest press trainer of the present application is trained by the trainee pushing the swing assembly 300 with both arms, so the armrest, swing arm and support frame 201 are set as two in the above description, and in actual operation, the transmission member 401, steering member 402, connecting member 403, rotating member 501, adjusting member 502, resistance member 600, limit member 700 and placement frame 800 are also set as two accordingly.

[0081] Reference Figures 1 to 4In the actual use of the chest press training device of this embodiment, the trainer selects an appropriate counterweight from the placement frame 800 and installs it on the resistance member 600. The trainer adjusts the seat height through the positioning member and the positioning groove and sits on the seat. The trainer holds the armrest and pushes the swing arm to move away from the main frame, thereby pulling the steering member 402 to rotate through the transmission member 401. The second turning point of the steering member 402 rotates clockwise around the first turning point, and then pulls the rotating member 501 to swing obliquely upward through the connecting member 403, and the rotating member 501 The vertical distance from the connection point with the main frame to the line of action of gravity of the resistance end of the resistance member 600 is the length of the resistance arm S. During the swinging process, the adjusting member 502 pushes the resistance member 600 to rotate relative to the rotating member 501, and the angle between the resistance member 600 and the rotating member 501 increases. The length of the resistance arm S increases accordingly, while the load on the resistance member 600 remains unchanged. Therefore, the resistance in the process of the connecting member 403 pulling the rotating member 501 to swing obliquely upward increases with the increase in the length of the resistance arm S to meet the training needs of the trainee.

[0082] It should be noted that the reference Figure 2 In the initial state, that is, when the swing component 300 does not pull the adjustment component 500 and the resistance member 600, the length of the resistance arm is essentially the vertical distance from the connection point A between the rotating member 501 and the main frame to the resistance end point B of the resistance member 600.

[0083] When the swing component 300 pulls the adjustment component 500 and the resistance member 600 to move, the resistance end point B of the resistance member 600 moves to point C. At this time, the length of the resistance arm is essentially the vertical distance from the connection point A between the rotating member 501 and the main frame to the resistance end point C of the resistance member 600.

[0084] When the swing component 300 pulls the adjustment component 500 and the resistance member 600 to continue moving until the resistance end point C of the resistance member 600 moves to point D, during this process, the adjustment component 500 pushes the resistance member 600 to rotate relative to it. At this time, the length of the resistance arm is essentially the vertical distance from the connection point A between the rotating member 501 and the main frame to the line of action of gravity from the resistance end point D of the resistance member 600; the resistance arm continues to increase during the movement, thereby continuously increasing the resistance. Specific embodiment 2

[0086] The present application also provides a chest press training device, which is different from the specific embodiment 1 in the following aspects:

[0087] Reference Figure 5In some embodiments, the adjustment component 500 includes a rotating member 501 and an adjusting member 502; one end of the rotating member 501 is rotatably disposed on the second stabilizing member 203, and the other end is rotatably connected to the resistance member 600, and the middle part between the two ends of the rotating member 501 is used for rotatably connecting with the connecting member 403, so that the swinging component 300 can pull the rotating member 501 and the resistance member 600 to rotate relative to the supporting component 200 through the transmission component 400.

[0088] One end of the resistance member 600 is rotatably connected to the rotating member 501, and the other end is provided with an extension rod, which is used to place a counterweight.

[0089] One end of the adjusting member 502 is rotatably disposed on the second stabilizing member 203, and the connecting pivot point of the adjusting member 502 and the second stabilizing member 203 is located on the side of the connecting pivot point of the rotating member 501 and the second stabilizing member 203 close to the base frame 100, and the other end of the adjusting member 502 is rotatably disposed between the two ends of the resistance member 600; the rotating member 501 and the adjusting member 502 are actually staggered, wherein the adjusting member 502 is used to pull the resistance member 600 to rotate relative to the rotating member 501 when the swinging assembly 300 drives the resistance member 600 to move in a direction away from the supporting assembly 200, thereby reducing the angle between the rotating member 501 and the resistance member 600, so that the resistance to the swinging assembly 300 continues to decrease.

[0090] Reference Figures 5 and 6 In the actual use of the chest press training device of this embodiment, the trainer selects an appropriate counterweight from the placement frame 800 and installs it on the resistance member 600. The trainer adjusts the seat height through the positioning member and the positioning groove and sits on the seat. The trainer holds the armrest and pushes the swing arm to move away from the main frame, thereby pulling the steering member 402 to rotate through the transmission member 401. The second turning point of the steering member 402 rotates clockwise around the first turning point, and then pulls the rotating member 501 to swing obliquely upward through the connecting member 403, and the rotating member 501 The vertical distance from the connection point with the main frame to the line of action of gravity of the resistance end of the resistance member 600 is the length of the resistance arm S. During the swinging process, the adjusting member 502 pulls the resistance member 600 to rotate relative to the rotating member 501, and the angle between the resistance member 600 and the rotating member 501 decreases, and the length of the resistance arm S decreases accordingly, while the load on the resistance member 600 remains unchanged. Therefore, the resistance in the process of the connecting member 403 pulling the rotating member 501 to swing obliquely upward decreases as the length of the resistance arm S decreases, so as to meet the training needs of the trainee.

[0091] The chest press trainer of the present application adjusts the size of the resistance arm during the movement of the resistance member 600 driven by the swinging assembly 300 through the relative rotation cooperation between the adjustment assembly 500 and the resistance member 600, thereby achieving the technical effect of continuously controlling the increase or decrease of resistance; the transmission assembly 400 allows the trainee to flexibly adjust the direction of force, and the placement position of the counterweight block can be lower than the training position, which facilitates the adjustment of the counterweight block and improves the stability of the chest press trainer; the position of the seat cushion can be flexibly adjusted according to the height of the trainee through the cooperation between the positioning member and the positioning groove; and the limiting member 700 is provided to prevent the resistance member 600 from driving the adjustment assembly 500 to continue to move toward the direction close to the base frame 100 in the natural drooping state, thereby avoiding damage to the structure of the adjustment assembly 500.
