Description

Technical Field

[0001] This utility model belongs to the field of medical rehabilitation equipment, and specifically relates to a lower limb activity training device. Background Technology

[0002] The assisted walking device is mainly used by people in the lower limb rehabilitation stage (postoperative rehabilitation or recovery exercise). When using it, the user walks slowly by holding the assisted walking device and moves it forward continuously. When the user feels tired, they can stop moving to rest and recover their strength or relieve pain. However, the user still needs to be standing when stopping, which is not conducive to resting and recovery and continuing exercise. In addition, a caregiver needs to be present to supervise the user during the movement to prevent the user from overexerting themselves or collapsing due to excessive exercise.

[0003] Publication document CN202323332454.2 discloses a walking aid, characterized by comprising: two support components arranged opposite to each other; two armrest components respectively disposed on top of the two support components, the armrest components moving along a second direction on the support components; and a first drive component drivenly connected to the armrest components and driving the armrest components to move along a first direction. While this document discloses a walking aid, it still presents the problem of inconvenience for resting.

[0004] Publication document CN202221545532.X discloses a walking aid, including a bottom support with walking components. The bottom support is characterized by an adjustable top support, which includes a first grip and a shelf. Although a seat is added, the user still needs to turn around to sit down. During this process, the user is prone to falling due to a lack of effective support, making it inconvenient for rest.

[0005] Although there are currently walking aids with seats, users need to turn around or move to the front of the walking aid to sit down. During the process of turning around or moving to sit down, it is easy to fall. It is also inconvenient for users to rest and recover during exercise, which directly leads to shorter exercise time and walking distance, longer rehabilitation time, and affects the rehabilitation effect.

Detailed Implementation

[0029] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit this application or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0030] Example 1

[0031] like Figure 1 and Figure 7 As shown, the lower limb activity trainer includes a rear-opening movable frame 1 and a movable seat installed on the left and / or right side inside the movable frame 1. The movable frame 1 is equipped with a guide rail 2 for moving the movable seat toward the opening side of the movable frame 1. The movable seat is provided with a seat plate 4 that can be erected or laid flat.

[0032] Specifically, in this embodiment, the movable frame 1 is a rectangular frame with an opening on the rear side. Damping wheels are installed at the four corners of the bottom of the movable frame 1, and movable seats are installed on the left and right sides inside the movable frame 1.

[0033] The movable seat includes a frame 3, a support rod 5 and a seat plate 4. The upper end of the frame 3 facing the guide rail 2 is provided with a sliding groove that is adapted to the guide rail 2. The opening of the sliding groove is downward. The seat plate 4 for users to sit on is rotatably mounted on the frame 3.

[0034] The stand 3 moves along the guide rail 2 toward the opening of the movable frame 1 and places the seat 4 outside the opening. The user lays the seat 4 inward to a horizontal position. At this time, the seat 4 is behind the user. After the seat 4 is moved into place, the user can slowly sit down by holding onto the movable frame 1.

[0035] The support rod 5 is rotatably connected to the bottom end of the seat plate 4. When the seat plate 4 is in a horizontal state, the bottom end of the support rod 5 abuts against the ground. The support rod 5 and the upright frame 3 provide stable support for the seat plate 4. After the seat plate 4 is erected, the support rod 5 can be folded up to avoid taking up space.

[0036] The bottom of the mobile seat is equipped with guide wheels 12 to contact the ground, which facilitates movement and provides stable support when the user sits on the seat plate 4.

[0037] Working principle: When users feel tired during exercise, they can move the movable seat along guide rail 2 to the back of the user, then slowly sit down. After a period of recovery, they can slowly stand up and then move the movable seat back to its original position.

[0038] In this application, by setting up the movable frame 1, guide rail 2 and movable seat, when the movable seat moves behind the user, the seat plate 4 and movable frame 1 cooperate to form a wrap-like state for the user, which can provide multiple support points as the user slowly sits down, without the need to turn around or stand up to recover, effectively solving the problem that current walking aids are not convenient for rest.

[0039] Example 2

[0040] like Figures 1-7 As shown, the structure of this embodiment is roughly the same as that of embodiment 1. This embodiment is further optimized based on embodiment 1. In order to facilitate the raising and lowering of the seat plate 4, a stop bar 6 is installed on the moving frame 1 to make the seat plate 4 fall towards the inside of the arc frame, and a return bar 7 is installed on the moving frame 1 to make the seat plate 4 rotate upward.

[0041] The support frame 3 is equipped with a support rod 8 located below the pivot of the seat plate 4. The support rod 8 is also located inside the seat plate 4. The support rod 8 is used to support the seat plate 4 when it falls down, so that the seat plate 4 is in a horizontal state after it falls down, making it convenient for users to sit down.

[0042] Meanwhile, in order to further improve the load-bearing capacity of the seat plate 4, a limiting rod 9 located on the outside of the seat plate 4 is also installed on the upright 3. The limiting rod 9 is located above the pivot of the seat plate 4. The horizontal gap between the limiting rod 9 and the supporting rod 8 is equal to the thickness of the seat plate 4 after it falls down. When the seat plate 4 is in a horizontal state, the bottom end of the limiting rod 9 abuts against the top end of the seat plate 4.

[0043] The support rod 8 and the limiting rod 9 can be used to limit the seat plate 4 after it falls down, thereby increasing the load-bearing capacity of the seat plate 4.

[0044] Specifically, one end of the stop bar 6 is fixedly connected to the movable frame 1, and the other end of the stop bar 6 is located on the moving trajectory of the seat plate 4 as it moves with the upright 3. As the seat plate 4 moves with the upright 3, the stop bar 6 tilts and blocks the seat plate 4, and the seat plate 4 falls towards the inside of the seat plate 4 under the action of the stop bar 6.

[0045] One end of the return rod 7 is fixedly connected to the movable frame 1. The other end of the return rod 7 passes around the receiving rod 8 and tilts towards the return trajectory of the upright 3 and gradually tilts towards the upright 3. The height of the other end of the return rod 7 is higher than the bottom height of the seat plate 4 after it falls down. The gap between the other end of the return rod 7 and the inner side of the upright 3 is equal to or slightly greater than the thickness of the seat plate 4.

[0046] When the user moves the upright 3 outward, the seat 4 is blocked by the stop bar 6 and falls down. After falling down, the seat 4 is in a horizontal state under the action of the support bar 8 and the limit bar 9, which makes it convenient for the user to sit down. When the upright 3 is retracted, the seat 4 rotates upward and gradually stands up under the action of the return bar 7. The seat 4 is in a retracted state to avoid affecting the user's walking.

[0047] Example 3

[0048] like Figures 1-7 As shown, the structure of this embodiment is roughly the same as that of embodiment 2. This embodiment is further optimized based on embodiment 2. In order to prevent the seat plate 4 from falling down directly after being blocked by the stop bar 6 and making a loud collision sound, a spring 10 connected to the bottom end of the seat plate 4 is installed on the side of the receiving rod 8 near the seat plate 4. The spring 10 provides a certain pulling force during the process of the seat plate 4 falling down, so that the seat plate 4 falls down slowly.

[0049] To prevent the seat plate 4 from falling down after being blocked by the return rod 7 and standing upright, a magnet 11 corresponding to the seat plate 4 is provided on the upright 3. The seat plate 4 is attracted to the magnet 11. In this embodiment, the seat plate 4 is made of iron. The attraction of the magnet 11 to the seat plate 4 prevents the seat plate 4 from falling down again after standing upright.
