DETAILED DESCRIPTION

[0025] In order to more clearly illustrate the technical scheme in the embodiments of the utility model or prior art, the utility model will be briefly introduced in combination with the drawings and the description of the embodiments or prior art, and obviously, the following description of the structure of the drawings is only some embodiments of the utility model, and for those skilled in the art, other drawings can be obtained without creative labor. It needs to be explained that the description of these embodiment modes is used to help understanding the utility model, but does not constitute the limitation of the utility model.

[0026] EMBODIMENT

[0027] In view of the various installation limitations, use limitations, and high installation and maintenance costs of the four types of common stair ascending and descending auxiliary devices (i.e. general lifting device, crawler-type stair ascending and descending wheelchair, step-type manned stair climbing machine, and track-type stair climbing machine), we propose a low-cost, simple-structure, easy-to-install and maintain upper limb supporting device for assisting stair ascending and descending, which can be installed and used in various stair environments; the specific scheme is as follows:

[0028] For example Figures 1-2As shown, the embodiment provides an upper limb supporting device for assisting in going up and down stairs, specifically comprising a slide rail 1, wherein the slide rail 1 is a square steel tube; and the slide rail 1 is installed on the wall of the stairway side through a support cooperating with an expansion screw along the inclined angle of the stairs; wherein the support for installing the slide rail 1 can adopt an I-shaped metal support with a large contact area with the wall surface, and the support and the slide rail 1 are fixed by any one of bolt or welding.

[0029] As shown, a sliding mechanism is slidingly installed outside the slide rail 1; and the sliding mechanism comprises a main fastener 3 and two auxiliary fasteners 2; wherein the two auxiliary fasteners 2 are oppositely arranged, and the two auxiliary fasteners 2 are fixedly installed together with the main fastener 3 by bolts; a sliding groove for accommodating the slide rail 1 is formed between the two auxiliary fasteners 2 and the main fastener 3, and a gap is left between the two auxiliary fasteners 2 to facilitate the passage of the support for installing the slide rail 1, which can effectively avoid the support for installing the slide rail 1 hindering the movement of the sliding mechanism on the slide rail 1. Figures 1-4

[0030] Under the premise of a pure mechanical structure, in order to realize the upper limb supporting of the elderly in the process of going up and down stairs, the side of the auxiliary fastener 2 away from the main fastener 3 is provided with a mounting groove A10, and a filling block A11 and a friction block B302 are respectively installed in the mounting groove A10; a horizontal rod handle 9 is installed in the middle of the main fastener 3 through a mounting piece 8; one mounting groove B301 is arranged on each of the main fasteners 3 on both sides of the horizontal rod handle 9, and a friction block B302 and a filling block B303 are respectively installed in the two mounting grooves B301; and the filling block A11 and the friction block B302 are arranged at one end of the sliding mechanism close to the lower stairs; the filling block B303 and the friction block A12 are arranged at one end of the sliding mechanism close to the upper stairs, wherein the filling block A11 and the filling block B303 are both composed of metal blocks; and the friction block A12 and the friction block B302 are both composed of rubber blocks.

[0031] The friction block A12 and the friction block B302, the filling block A11 and the filling block B303 in the entire sliding mechanism adopt a cross structure design, in the use process, when the elderly go upstairs, the horizontal rod handle 9 is held in the chest direction to collect force, so that the sliding mechanism composed of the main fastener 3 and the auxiliary fastener 2 is angularly offset, so that the friction block A12 and the friction block B302 are in contact with the surface of the slide rail 1, and the higher the friction coefficient of the friction block, the greater the force collected by the user, the more stable the locking effect of the sliding mechanism, thereby realizing the force collection when going upstairs, when the sliding mechanism needs to be moved forward during the process of going upstairs, the horizontal rod handle 9 is only needed to be pushed forward, so that the friction block A12 and the friction block B302 are separated from the slide rail 1, so that the filling block with a low friction coefficient is in contact with the slide rail 1, thereby enabling the sliding mechanism to normally move upwards along the stairs.

[0032] ​When using the sliding mechanism to go downstairs, the elderly only need to grasp the horizontal push handle with both hands and apply force forward to make friction blocks A12 and B302 contact the surface of the slide rail 1, thereby locking the sliding mechanism and making it easier for the elderly to use the sliding mechanism to go downstairs. When it is necessary to move the sliding mechanism during the descent, simply hold the horizontal bar handle 9 and apply force towards the chest to make friction blocks A12 and B302 disengage from the slide rail 1, so that the low-friction filler block contacts the slide rail 1. While keeping the angle of the horizontal bar handle 9 unchanged, push the sliding mechanism forward to allow the sliding mechanism to move normally down the stairs.

[0033] like Figures 1-5 As shown, due to the limited width of the stairwell, in order to avoid obstructing normal passage up and down the stairs, the horizontal bar handle 9 is installed on the main fastener 3 in a hinged manner. Specifically, a storage groove 4 is provided in the middle of the main fastener 3; and a positioning groove 5 is provided at the bottom of the main fastener 3 corresponding to the storage groove 4. The mounting part 8 is rotatably installed at the bottom of the storage groove 4 through the pivot 7, and a locking mechanism 6 is also installed on the storage groove 4.

[0034] Specifically, the mounting component 8 includes a sleeve 801 and a positioning post 802. The positioning post 802 is integrally formed with the sleeve 801, and the size of the positioning post 802 is adapted to the positioning groove 5. The bottom end of the crossbar handle 9 is fixedly inserted into the sleeve 801. There are two sets of locking mechanisms 6, which are symmetrically installed on both sides of the storage groove 4. The locking mechanism 6 includes a mounting sleeve 601, which is welded to the groove wall of the storage groove 4. A fixing cap 605 is screwed onto the tail end of the mounting sleeve 601. The interior of the mounting sleeve 601 is provided with a diameter and a mounting cap 605. A steel ball 603 with an inner diameter that matches the sleeve 601 is provided. A spring 604 is provided between the steel ball 603 and the fixing cap 605. The groove wall of the storage groove 4 has a through hole 602 with a size smaller than the diameter of the steel ball 603 at the position corresponding to the mounting sleeve 601. When the entire upper limb assist device is idle, the crossbar handle 9 and the mounting part 8 can be flipped up and stood upright. The locking mechanism 6 is used to lock it, so that it can be stably kept upright without the action of external force. The structural design of the locking mechanism 6 makes the flipping operation of the crossbar handle 9 convenient and labor-saving.

[0035] Since the intended users are elderly people, in order to prevent them from accidentally falling down the stairs while going up or down, such as Figure 6 As shown, a wristband 13 is also attached to the handle 9 of the horizontal bar. When the elderly use this device, they can put the wristband 13 on their wrists, which can effectively prevent the elderly from falling directly down the stairs after a sudden fall.

[0036] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
