The type A panel has a first protrusion, and the type B panel has a second protrusion.

[0008] The support member is disposed between the first plate and the second plate to support the first plate or the second plate, so that the first plate or the second plate is inclined.

[0009] The leg exercise device has at least a first usage state and a second usage state:

[0010] When the leg exercise device is in the first use state, the first plate is horizontally set and serves as the base plate, and the second plate is supported by the support member, so that the second plate is set at an angle. The B-shaped panel of the second plate is used to contact the sole of the user's foot.

[0011] When the leg exercise device is in the second use state, the second plate is horizontally set and serves as the base plate, and provides support to the first plate through the support member, so that the first plate is set at an angle, and the A-shaped panel of the first plate is used to contact the sole of the user's foot.

[0012] When the leg and foot exercise device is in its first and second usage states, users can perform stretching exercises using the stretching board. Simultaneously, with the first and second panels respectively equipped with raised structures (first and second protrusions), users can choose between Type A and Type B panels for stretching exercises, improving the product's full utilization and flexibility. When the first and second protrusions are of different sizes, structures, and types, the Type A and Type B panels become different panels, providing users with different user experiences and exercise effects, increasing the product's versatility and further enhancing its flexibility.

[0013] Furthermore, the support member is movably disposed between the first plate and the second plate;

[0014] The first plate and the second plate are connected by a hinge shaft, which allows the first plate and the second plate to rotate relative to each other at the hinge point, with a rotation range of at least 0° to 180°, so as to realize the folding or unfolding function;

[0015] The leg exercise device also has a third, a fourth, and a fifth usage state:

[0016] When the leg exercise device is in the third use state, the first plate is set horizontally and serves as the base plate, the second plate is stacked on top of the first plate, and the B-shaped panel of the second plate is used to contact the user's soles.

[0017] When the leg exercise device is in the fourth use state, the second plate is horizontally set and serves as the base plate, the first plate is stacked on top of the second plate, and the A-shaped panel of the first plate is used to contact the user's sole.

[0018] When the leg exercise device is in the fifth use state, the first plate and the second plate are respectively horizontally arranged, and the A-type panel of the first plate and the B-type panel of the second plate are both used to contact the user's soles.

[0019] When the leg and foot exercise device is in the third, fourth, and fifth usage states, the user can perform foot exercises using the acupressure mat.

[0063] The present invention will now be described in detail with reference to the accompanying drawings.

[0064] like Figures 1-10 As shown, this application provides a leg exercise device, including a first plate 10, a second plate 20, and a support member 30;

[0065] The first plate 10 and the second plate 20 are hinged together. The panel on the side of the first plate 10 away from the second plate 20 is a type A panel 110, and the panel on the side of the second plate 20 away from the first plate 10 is a type B panel 210. The type A panel has a first protrusion 102, and the type B panel has a second protrusion 105.

[0066] The support member 30 is disposed between the first plate 10 and the second plate 20 to support the first plate 10 or the second plate 20, so that the first plate 10 or the second plate 20 is inclined.

[0067] The leg exercise device has at least a first use state and a second use state:

[0068] When the leg exercise device is in its first use state (e.g.) Figures 1-3 As shown), the first plate 10 is horizontally set and serves as the base plate, and the second plate 20 is supported by the support member 30, so that the second plate 20 is set at an angle. The B-type panel 210 of the second plate 20 is used to contact the sole of the user's foot.

[0069] When the leg exercise device is in the second use state (not shown in the figure), the second plate 20 is set horizontally and serves as the base plate, and provides support to the first plate 10 through the support member 30, so that the first plate 10 is set at an angle, and the A-shaped panel 110 of the first plate 10 is used to contact the sole of the user's foot.

[0070] When the leg exercise device is in its first and second usage states, users can perform stretching exercises using the stretching board. Simultaneously, with the first plate 10 and the second plate 20 respectively equipped with raised structures (first protrusion 102 and second protrusion 105), users can perform stretching exercises using either the A-type panel 110 or the B-type panel 210, improving the product's full utilization and flexibility. When the first protrusion 102 and the second protrusion 105 are protrusions of different sizes, structures, and types, the A-type panel 110 and the B-type panel 210 are different panels, providing users with different user experiences and exercise effects, increasing the product's multi-functionality and further enhancing its flexibility.

[0071] In this embodiment, the support member 30 is movably disposed between the first plate 10 and the second plate 20;

[0072] The first plate 10 and the second plate 20 are connected by a hinge shaft 50, which allows the first plate 10 and the second plate 20 to rotate relative to each other at the hinge point. The range of rotation is at least 0° to 180° to achieve the folding or unfolding function.

[0073] The leg exercise device also has a third, fourth, and fifth usage state:

[0074] When the leg exercise device is in the third usage state (e.g.) Figure 4 As shown), the first plate 10 is horizontally arranged and serves as the base plate, and the second plate 20 is stacked on top of the first plate 10. The B-shaped panel 210 of the second plate 20 is used to contact the user's foot.

[0075] When the leg exercise device is in the fourth use state (not shown in the figure), the second plate 20 is set horizontally and serves as the base plate, and the first plate 10 is stacked on top of the second plate 20. The A-shaped panel 110 of the first plate 10 is used to contact the user's soles.

[0076] When the leg exercise device is in the fifth usage state (e.g.) Figure 6 As shown), the first plate 10 and the second plate 20 are horizontally arranged. The A-type panel 110 of the first plate 10 and the B-type panel 210 of the second plate 20 are both used to contact the user's foot.

[0077] When the leg and foot exercise device is in the third, fourth, and fifth usage states, the user can perform foot exercises using the acupressure mat. In the third usage state, the B-type panel 210 of the second plate 20 is used for foot exercises; in the fourth usage state, the A-type panel 110 of the first plate 10 is used; and in the fifth usage state, the user can choose to use the A-type panel 110 of the first plate 10 and the B-type panel 210 of the second plate 20 separately or simultaneously for foot exercises. Therefore, the leg and foot exercise device provided in this application further increases the product's versatility and flexibility of use.

[0078] When switching between the first and second use states of the leg exercise device, the installation positions of the heel protector 40 and the support 30 need to be switched. When the leg exercise device is switched to the third, fourth, and fifth use states, the heel protector 40 and the support 30 can be removed, or the support 30 can be stored, or the heel protector 40 can remain in its original position.

[0079] like Figure 1 and Figure 10 As shown, in this embodiment, the hinge shaft 50 has a first rotating shaft 510 and a second rotating shaft 520, and the axis of the first rotating shaft 510 and the axis of the second rotating shaft 520 are arranged parallel to each other.

[0080] The first plate 10 is rotatably mounted on the first rotating shaft 510, and the second plate 20 is rotatably mounted on the second rotating shaft 520. The first plate 10 and the second plate 20 are hinged together by the first rotating shaft 510 and the second rotating shaft 520 of the hinge shaft 50.

[0081] Compared to using a single pivot to hinge the first plate 10 and the second plate 20, using a hinge shaft 50 with a first pivot 510 and a second pivot 520 to hinge the first plate 10 and the second plate 20 respectively makes it less likely for the first plate 10 and the second plate 20 to interfere with each other. This allows for a smoother and more seamless adjustment of the relative positions of the first plate 10 and the second plate 20, and also makes it easier for the leg exercise device to be in its fifth use state for users to perform acupressure exercises.

[0084] When the leg exercise device is in the third or fourth use state, the first locking part and the second locking part are locked together.

[0085] The locking structure 60 ensures that when the leg exercise device is in the third and fourth use states, the first plate 10 and the second plate 20 are engaged and not easily misaligned, thereby protecting the hinge shaft 50 and enhancing its service life and safety during exercise. Simultaneously, the third and fourth use states of the leg exercise device can also be the storage state of the device.

[0086] In this embodiment, mounting structures 70 are respectively provided on the panel of the first plate 10 facing the A-type panel 110 and located on the side closer to the second plate 20, and on the panel of the second plate 20 facing the B-type panel 210 and located on the side closer to the first plate 10.

[0088] The mounting end 320 of the support member 30 is used to install and cooperate with the mounting groove 710, and the locking end 310 of the support member 30 is used to install and cooperate with the locking groove 720.

[0089] In this embodiment, the support member 30 is a rectangular frame structure. The rectangular frame structure support member 30 has a protruding end 330 at the snap-fit ​​end 320 position. The protruding end 330 and the snap-fit ​​groove 710 can increase the support force and increase the firmness of the connection.

[0090] In this embodiment, the locking groove 720 includes six spaced grooves, which respectively cooperate with the support member 30 to make the first plate 10 or the second plate 20 have different tilt angles.

[0091] The mounting structure 70 also includes a storage groove 730 for storing the support member 30;
