Description

[Technical Field]

[0001] The present invention relates to a wheelchair for moving up and down stairs, in which the wheelchair of an elderly person or a disabled person is placed on a base that is integrated with guide rails and guide rollers fixed to the stairs, and the wheelchair can be moved up and down stairs while in the wheelchair, and when not in use, the base made up of two pieces can be folded and stored on the left and right sides. [Background technology]

[0002] In the past, in an emergency, several people had to help move wheelchairs carrying elderly or disabled people downstairs. Summary of the Invention [Problem to be solved by the invention]

[0003] This has resulted in the following problems: (i) When an elderly or disabled person is in a wheelchair, several people need to help them move up and down the stairs, and there is a risk of them slipping when they are in a hurry. The present invention has been made to solve these problems. [Means for solving the problem]

[0004] Tall support posts for fixedly mounting guide rails are installed at the left and right corners of the upper steps of the stairs, and guide rails with legs the length of the stairs, on which stopper protrusions are attached on the top surface of the guide rails to ensure safe movement by dividing the sliding of the base into several times, are fixed to the support posts on the left and right, two guide rollers are installed on each of the left and right guide rails, which are integrated with the hanging material connecting the base, and stopper members are fixed on the left and right undersides of the base, which can temporarily stop the sliding movement of the base when they come into contact with the protrusions on the top surface of the guide rails, and when the base is not in use, it is separated in the middle. TIFF2025182647000002.tif9149Axle bearing brackets are provided at the top and bottom of both ends of the base, and fixed rods are inserted into the fixed rod insertion wheel brackets provided at four points on the base to combine the two bases into one base. The wheels are dropped into the long holes in the base, and the wheelchair is secured with a belt or similar to ensure safety. The wheelchair stored in the base can be pulled or pushed by hand, or a long rope can be attached to the lift, allowing the lift to be moved up and down from above. This is a wheelchair stair-climbing platform lift characterized by the above features. [Effects of the Invention]

[0005] The guide rails, which are integrated with the tall support posts on the left and right sides of the stairs, and the base, which is integrated with the guide rollers, allow elderly people and people with disabilities in wheelchairs to safely move up and down the stairs by themselves while remaining in their wheelchairs.When not in use, the base's fixing rod can be removed and the base can be folded to the left and right sides for storage. [Brief explanation of the drawings]

[0006] [Figure 1] FIG. 1 is an overall side view of the present invention installed on a staircase. [Figure 2] FIG. 1 is a plan view of a base on which a wheelchair of the present invention is placed. [Figure 3] This is a front view showing an example of use in which the base of the component of the present invention is suspended via left and right guide rails and guide rollers, and the wheels of the wheelchair fit into the left and right long holes of the stopper provided on the base, allowing the wheelchair to move safely up and down. [Figure 4] This is a diagram of the fixing rod that combines the two bases of the present invention into a single base. [Figure 5] This is a diagram showing an example of how the base of the component of the present invention can be used when not in use, by removing the fixing rod and opening the base, which is divided in the middle, to the left and right and storing it on the side wall of the stairs. DETAILED DESCRIPTION OF THE INVENTION

[0007] Hereinafter, an embodiment of the present invention will be described. Tall support posts for fixedly mounting guide rails are installed at the left and right corners of the upper steps of the stairs, and guide rails with legs the length of the stairs, on which stopper protrusions are attached on the top surface of the guide rails to ensure safe movement by dividing the sliding of the base into several times, are fixed to the support posts on the left and right, two guide rollers are installed on each of the left and right guide rails, which are integrated with the hanging material connecting the base, and stopper members are fixed on the left and right undersides of the base, which can temporarily stop the sliding movement of the base when they come into contact with the protrusions on the top surface of the guide rails, and when the base is not in use, it is separated in the middle. TIFF2025182647000003.tif10149 Bearing brackets that receive the axles are provided at the top and bottom of both ends of the base, and fixed rods are inserted into fixed rod insertion wheel brackets provided at four points on the base to combine the two bases into one, the wheels are dropped into the long holes in the base, and the wheelchair is secured to safety with a belt or the like.The wheelchair stored in the base can be pulled or pushed by hand, or a long rope can be attached to the lift, allowing the lift to be moved up and down from above. The present invention has the above-described configuration. When using this, fix the support posts to the two left and right corners of the upper staircase with wood screws, fix the bracket to the top of the support post, and attach the guide roller integrated with the hanging material to the guide rail. TIFF2025182647000004.tif11151The two bases are inserted into the lift to combine them into one base, the wheels are dropped into the long holes in the left and right recesses of the base, and the wheelchair and lift are stabilized with a belt or the like, allowing the wheelchair to be pushed or pulled, or the wheelchair can be raised or lowered from above using a long rope.
