[0016] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the relevant utility model and not intended to limit the scope of the utility model. Furthermore, it should be noted that, for ease of description, only the parts relevant to the utility model are shown in the accompanying drawings.

[0017] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0018] Please refer to Figures 1-4 The present invention relates to a seated and reclining double-position leg support device, comprising: a main frame 100 on which a leg support plate 110 is fixedly connected; a resistance providing mechanism 200; and a torso support mechanism 300, which includes a connecting seat 310, a seat cushion 320, a back cushion 330, and two shoulder pads 340. The connecting seat 310 is slidably connected to the main frame 100, the seat cushion 320 is fixedly connected to the connecting seat 310, the back cushion 330 is fixedly connected to the connecting seat 310 at an adjustable fixed angle, the shoulder pads 340 are fixedly connected to the connecting seat 310, and the back cushion 330 can pass between the two shoulder pads 340. The resistance providing mechanism 200 provides resistance to the connecting seat 310 away from the leg support plate 110.

[0019] In an embodiment of this utility model, the main frame 100 is placed on the ground, and the main frame 100 is fixedly connected to the leg pedal 110. The leg pedal 110 can be set as a whole or separately. Figure 1 As shown, the leg press boards 110 are set separately. When performing seated leg press training, one can step on one of the leg press boards 110; when performing supine leg press training, one can step on the other of the leg press boards 110, which makes it convenient for users to perform leg press training in different postures.

[0020] The torso support mechanism 300 supports the torso and includes a connecting seat 310, a seat cushion 320, a back cushion 330, and two shoulder pads 340. The connecting seat 310 is slidably connected to the main frame 100, sliding relative to the main frame 100 during leg-pressing exercises. The seat cushion 320 is fixedly connected to the connecting seat 310 and supports the user's buttocks. The back cushion 330 supports the user's back and is fixedly connected to the connecting seat 310 at an adjustable angle. The angle between the back cushion 330 and the seat cushion 320 is adjustable. During seated leg-pressing exercises, the angle between the back cushion 330 and the seat cushion 320 is smaller, close to 90°. During supine leg-pressing exercises, the angle between the back cushion 330 and the seat cushion 320 is larger, close to 180°. The user can adjust the angle between the back cushion 330 and the seat cushion 320 according to their training posture to meet different training needs. Shoulder pads 340 are fixedly connected to connecting seat 310. During supine leg extension training, the angle between back pad 330 and seat pad 320 is relatively large, close to 180°. The user's shoulders will press against shoulder pads 340, facilitating the sliding of connecting seat 310 relative to the main frame 100. By adjusting the angle between back pad 330 and connecting seat 310, that is, adjusting the angle between back pad 330 and seat pad 320, users can switch between seated and supine leg extensions, thereby meeting different training needs.

[0021] During leg extension training, as the leg extends, the connecting seat 310 moves away from the leg extension plate 110. The resistance providing mechanism 200 provides resistance as the connecting seat 310 moves away from the leg extension plate 110, thus providing resistance for the leg extension. Of course, the user can adjust the resistance provided by the resistance providing mechanism 200 according to their training needs to meet different training requirements.

[0022] Furthermore, the main frame 100 is fixedly connected to the first slide rail 120, and the connecting seat 310 is fixedly connected to the first sliding seat 311. The first sliding seat 311 is provided with a plurality of first rollers, and the first rollers are in rolling cooperation with the first slide rail 120.

[0023] In the embodiments of this utility model, the first roller and the first slide rail 120 are rolled together to achieve a sliding connection between the connecting seat 310 and the main frame 100, which ensures the smoothness of the sliding connection between the connecting seat 310 and the main frame 100 and reduces the friction between the connecting seat 310 and the main frame 100.

[0024] refer to Figure 1 Furthermore, the end of the first slide rail 120 away from the leg pedal 110 is tilted upward.

[0025] In this embodiment of the invention, the end of the first slide rail 120 away from the leg pedal 110 is inclined upwards. During the user's leg extension, the connecting seat 310 moves away from the leg pedal 110, and the user's own weight becomes a resistance. During the user's leg flexion, the connecting seat 310 moves closer to the leg pedal 110, and the user's own weight assists the movement of the connecting seat 310, making it easier for the connecting seat 310 to return to its original position.

[0026] Furthermore, the back pad 330 is fixedly connected to the fixing plate 331. One end of the fixing plate 331 is rotatably connected to the connecting seat 310. The fixing plate 331 is fixedly connected to an adjusting piece 332. The adjusting piece 332 is provided with a plurality of first adjusting holes 333. The adjusting piece 332 passes through the connecting seat 310. The connecting seat 310 is provided with a first pull pin. The first pull pin is inserted into any of the first adjusting holes 333 to fix the adjusting piece 332 and the connecting seat 310.

[0027] In this embodiment of the invention, the back cushion 330 is fixedly connected to the fixing plate 331, which provides support for the back cushion 330. Adjusting the angle between the back cushion 330 and the seat cushion 320 is achieved by inserting the first pull pin into different first adjustment holes 333. Specifically, when adjusting the angle between the back cushion 330 and the seat cushion 320, the first pull pin is pulled, disengaging it from the first adjustment hole 333. At this time, the fixing plate 331 can rotate relative to the connecting seat 310, thereby adjusting the angle between the back cushion 330 and the seat cushion 323. After adjusting the angle between the back cushion 330 and the seat cushion 323, the first pull pin is released, inserting it into the first adjustment hole 333. The adjusting piece 332 cannot move relative to the connecting seat 310, thus fixing the position of the back cushion 330.

[0028] Furthermore, the end of the adjusting piece 332 away from the fixed plate 331 is detachably fixedly connected to an anti-detachment component 334.

[0029] In this embodiment of the invention, during the adjustment of the angle between the backrest 330 and the seat cushion 320, the adjusting piece 332 moves relative to the connecting seat 310, and the adjusting piece 332 passes through the connecting seat 310. After the seated and reclining double-position leg extension device is installed, by setting the anti-disengagement component 334, the end of the adjusting piece 332 can be prevented from passing through the connecting seat 310, that is, the adjusting piece 332 is prevented from detaching from the connecting seat 310, thereby improving the reliability of the seated and reclining double-position leg extension device.

[0030] Furthermore, a first buffer block 314 is fixedly connected to the connecting seat 310, and the first buffer block 314 is located on the movement path of the fixed plate 331.

[0031] In the embodiments of this utility model, during the process of adjusting the angle between the back cushion 330 and the seat cushion 320, especially when switching from a sitting leg-raising posture to a lying leg-raising posture, when the back cushion 330 is lowered, the first buffer block 314 can stop the fixing plate 331 and reduce the impact on the fixing plate 331.

[0032] Furthermore, an adjusting tube 350 is sleeved inside the connecting seat 310. Multiple second adjusting holes are provided on the adjusting tube 350 at intervals. The connecting seat 310 is provided with a second pull pin 315. The second pull pin 315 is inserted into any of the second adjusting holes to fix the adjusting tube 350 and the connecting seat 310. The adjusting tube 350 is connected to the resistance providing mechanism 200 through a steel wire rope 400. Multiple pulleys 130 are rotatably connected to the main frame 100. The steel wire rope 400 passes around the pulleys 130.

[0033] In embodiments of this invention, the second pull pin 315 is inserted into different second adjustment holes to adjust the length of the adjusting tube 350 extending out of the connecting seat 310. Specifically, when it is necessary to adjust the length of the adjusting tube 350 extending out of the connecting seat 310, the second pull pin 315 is pulled, causing the second pull pin 315 to disengage from the second adjustment hole. At this time, the adjusting tube 350 can slide relative to the connecting seat 310, thereby adjusting the length of the adjusting tube 350 extending out of the connecting seat 310. After the length of the adjusting tube 350 extending out of the connecting seat 310 is adjusted, the second pull pin 315 is released, and the second pull pin 315 is inserted into the second adjustment hole. The adjusting tube 350 can no longer slide relative to the connecting seat 310, that is, the adjusting tube 350 is fixed to the connecting seat 310.

[0034] refer to Figure 4 A third buffer block 160 is fixedly connected to the main frame 100, and a stop plate 352 is set on the adjusting tube 350. The third buffer block 160 is located on the movement path of the stop plate 352, and the third buffer block 160 can stop and buffer the stop plate 352. By adjusting the length of the adjusting tube 350 extending out of the connecting seat 310, the distance between the connecting seat 310 and the leg pedal 110 at the initial position is changed. Specifically, the longer the adjusting tube 350 extends out of the connecting seat 310, the greater the distance between the connecting seat 310 and the leg pedal 110. This meets the different training needs of users.

[0035] The adjusting pipe 350 is connected to the resistance providing mechanism 200 via a steel wire rope 400. The adjusting pipe 350 moves with the connecting seat 310, and the resistance providing mechanism 200 provides force to the connecting seat 310 via the steel wire rope 400. The main frame 100 is rotatably connected to multiple pulleys 130. The steel wire rope 400 passes around the pulleys 130, which can reduce the friction on the steel wire rope 400.

[0036] refer to Figures 1-3Furthermore, the main frame 100 is fixedly connected to the second slide rail 140, and the resistance providing mechanism 200 includes a second sliding seat 210 and a bell hanger 220. The bell hanger 220 is fixedly connected to the second sliding seat 210, and the second sliding seat 210 is provided with a plurality of second rollers, which roll in cooperation with the second slide rail 140.

[0037] In an embodiment of this utility model, during the user's leg extension training, the connecting seat 310 moves away from the leg extension plate 110, the resistance providing mechanism 200 is lifted, and the gravity of the resistance providing mechanism 200 provides resistance for the connecting seat 310 to move away from the leg extension plate 110, that is, provides resistance for the leg extension.

[0038] The second roller and the second slide rail 140 roll together to enable the second sliding seat 210 to move along the second slide rail 140, ensuring the smooth movement of the resistance providing mechanism 200 and reducing friction.

[0039] The 220 bell hanger can suspend bells, allowing users to hang bells of different weights and numbers according to different training needs.

[0040] Furthermore, the main frame 100 is fixedly connected to a second buffer block 150, which is located on the movement path of the bell hanger 220.

[0041] In an embodiment of this utility model, during the descent of the resistance providing mechanism 200, the second buffer block 150 can buffer the impact of the resistance providing mechanism 200.

[0042] Furthermore, the shoulder pad 340 is fixedly connected to the connecting seat 310 via the first fixing tube 341. The end of the first fixing tube 341 away from the connecting seat 310 is set as the first grip 342. The connecting seat 310 is fixedly connected to the second fixing tube 360. The two ends of the second fixing tube 360 ​​are bent to form the second grip 361. The second grip 361 is located on both sides of the seat cushion 320.

[0043] In this embodiment of the invention, the first fixing tube 341 can support the shoulder pad 340. When performing supine leg extension exercises, the user's shoulders will press against the shoulder pad 340, and the user can grip the first handle 342 with both hands for easy power generation.
