Description

Wheelchair lift for disabled

The present invention relates to a wheelchair lift, and more particularly, by boarding a wheelchair on which a disabled person is boarded on a top plate, and safely as it is without changing the direction of entry while riding the wheelchair on the stage podium of the church or auditorium. It relates to a wheelchair lift for the disabled, which allows access and at the same time enables stable fixation of the platform after lifting to the height that is frequently used.

In general, disabled people who use wheelchairs mostly depend on electric wheelchairs for their lives and can move conveniently. It allows the use of means of transport such as vehicles.

In particular, the entrance into the building is through a dedicated ramp provided at the entrance of the building, and these facilities are increasing for disabled people in wheelchairs.

As described above, it is possible to use a wheelchair to climb the gentle slope, but in the case of a high church or pedestal, it is relatively difficult to enter because it is 70~90cm high from the ground.

Although it is possible to construct a ramp using a disabled person, since it takes up a lot of space, it is less efficient to use the space. In most cases, a ramp with a high inclination angle is installed, or an example of having a disabled person ride a wheelchair on the podium by supporting it separately. Most of them.

In fact, it is very difficult to put the disabled person and wheelchair on the pedestal, since most of the places do not have slope ramps.

If the inclination angle of the incline ramp is large as described above, it is difficult for the disabled to enter the podium alone while in a wheelchair, so several people around must help. There was a problem.

Looking at the technology related to the technology related to the wheelchair lift, Republic of Korea Patent No. 10-0936020 (name: low-floor wheelchair lift, registration date: December 31, 2009, hereinafter referred to as 'patent literature') is disclosed.

Looking at the fixing member 70 in more detail, as shown in the accompanying FIGS. 7 and 8, the lower side guide roller R of the link 30 is installed to be rotatably installed on the same axis line. A shaft hole (71a) and a coupling groove (71b) formed on one end side of the shaft hole (71), and the coupling protrusion (72a) having a magnet (M) attached to one end so as to be inserted into the coupling groove (71b) and coupled by magnetic force. ) and a plurality of split bars 72 having a coupling groove 72b on the other side of the coupling protrusion, and the length thereof is configured to be lengthened or shortened as a whole according to the number of the split bars connected.

One or more of the coupling grooves 71b and 72b and the coupling protrusion 72a are formed as shown in the drawings to form a mutual connection combination.

As described above, in the configuration of the fixing members 70 installed on both sides of the link 30, the dividing bar 72 is connected to a different length from the connecting bar 71, so that one end of the fixing member 70 is a lifting platform. It is configured to be variably supported and fixed in the guide part 12 of the base body 10 according to the corresponding height fixation of (20).
For reference, in the lift configuration of the present invention, the inclined footrest 14 is provided with a hanging jaw 14a to be hung to be seated on the support jaw 11, and on both sides of the upper surface in the longitudinal direction to prevent side separation of the wheelchair wheel. A guide 14b is formed, and several friction protrusions 14c are formed on the upper surface.
The reason why the departure preventing sills 23 of the elevator 20 are formed in pairs on the front and back sides of the access road is that the shape is formed in a low triangular protrusion shape, so that the handicapped person rides the wheelchair to the extent that the wheelchair side wheel rides over it. It is designed to make it easier to recognize the level of entry by allowing you to feel it even in a single state.
The wheel entry bridge 26 is connected and installed so as to be foldable by a hinge, and both sides thereof are formed to have a width that matches the width of the access road, and the guide 14b of the inclined entry footrest 14 has the same shape on both sides thereof. of the guide 26a is formed so as to be able to stand up from the entrance.

The operation according to the use of the wheelchair lift for the disabled according to the present invention to which the configuration is applied is described as follows.

First, the position of the lift 100 is close to the best position for a disabled person riding a wheelchair (W) to enter the stage (structure (1-1)) of the stage through the caster (C) provided on the side of the base body 10 as much as possible. In the arranged state, the rolling of the caster is stopped using the brake provided on the side of the caster (C), and the fixture 13 provided separately on the base body 10 is lowered to the fixture side in a state in close contact with the ground. The lift 100 is generally fixed so as not to flow from the ground by using a fixing lever provided in the .

In the same state as described above, the support jaws 11 provided on both sides of the front side of the base body 10 are hung on the hooking jaws 14a of the inclined footrest 14 to construct a gentle slope slope from the ground.

As shown in the attached FIGS. 9 and 10, the disabled person who rides the wheelchair (W) on the lift 100 set as described above directly enters along the inclined step step 14, and enters the inclined step step ( 14), the wheel of the wheelchair enters the access road 21 of the elevator 20 at the end of the end portion, so that it is possible to board the elevator.

Here, the wheel of the wheelchair (W) exceeds the departure threshold 23 protruding respectively on the front and rear sides of the access road when the front side small wheel and the rear side large wheel enter the access road 21, and at this time, the disabled person It can be easily recognized whether the current position of the wheel is accurately located on the access road 21 of the elevator 20 while crossing the departure bump, and it prevents the wheel from being easily pushed back and forth in the state that the departure bump is crossed.

In the state as described above, the disabled person waits for the lift by holding the handrails 25 standing upright on both sides of the lift.

That is, if the wheelchair is correctly positioned, the auxiliary assistant repeatedly operates the stepping pedal 50 by pressing the stepping pedal 50 and releasing the foot. In this operation, the hydraulic cylinder 40 is pumped, and the link 30 corresponding to each other is crossed in a horizontal state by the forward operation of the operation rod 40a together with the rotation of the hydraulic cylinder 40 by the operation of the hydraulic cylinder. It is possible to raise the elevator 20 by making it an unfolding motion.

The lift 20 can be lifted up and down about 1 meter according to the maximum allowable operating range of the link 30 .

If the elevation of the platform 20 is in a state of being leveled to the height of the target stage structure 1-1 or raised to a height of approximately 1 to 2 cm from the horizontal, the auxiliary assistant is fixed provided on the link 30 side. By rotating and fixing the member 70, the lifted platform 20 is fixed once more.

If the wheel entry bridge 26 provided in the access road 21 of the elevator 20 in the above state is extended toward the upper surface side of the structure 1-1 or the disabled person drives the wheelchair all the way, the wheels of the wheelchair are for the wheel entry As the bridge is pushed outward, the wheelchair enters through the upper surface of the stage-side structure (1-1).

Here, the fixing member 70 rotates both sides or rotates only one of the two fixing members on both sides to support the end in close contact with the guide part 12 on the side of the base body 10, so that the elevator 20 is lifted. It is made in a shape to prevent the descent of

For example, if the number of dividing bars 72 is reduced, the height of the elevator 20 can be fixed at a low position. Depending on the height of the structure, the number or length of the dividing bars is a combination of different dividing bars. By reducing or increasing the length of the fixing member of the length, it is possible to support the pushing of the link according to the height of the elevator.

The fixing member 70 is spaced from the link 30 moved from the inside of the guide part 12 on the side of the base body 10 according to a connection combination of the number of split bars 72 sequentially coupled to the connection bar 71 . It is a safety device that can prevent the link 30 and the elevator 20 from suddenly descending by momentarily dropping the hydraulic pressure acting on the hydraulic cylinder 40 by supporting it.

Since the fixing member has a structure in which a plurality of split bars are sequentially connected to the connecting bar, and the end of the split bar finally located in the guide part is positioned to support the lateral direction in which the link moves, it is stable and supported without breaking in the direction of force. possible.

With this safety secured, the disabled can safely enter the upper surface of the stage structure while in a wheelchair, and the elevator keeps the elevator from going down momentarily even in the process of getting on the platform to get off the stage again, thereby improving the stability of the disabled. make it possible to secure

The split bar 72 for the connecting bar 71 of the fixing member 70 allows the magnet M provided at the end of the engaging protrusion 72a to cause the connecting groove 71b of the connecting bar 71, When inserted into the coupling groove 72b of another dividing bar 72, it is easily attached by magnetic force, and the length can be determined according to the number of the dividing bar 72 from the connecting bar 71, which is based on the height of the frequently used structure. It can be set according to the overall length of the fixing member that can be stably positioned and fixed. This implements the lifting and fixing of the elevator platform without adjusting each one by fixing the fixing member that is adapted to use the lift for the disabled again as described above.

As described above, if the boarding of the disabled on the final wheelchair W on the elevator 20 in the structure 1-1 is confirmed, the fixing member 70 is rotated from the guide part 12 of the base body 10 When the operation rod 40a of the hydraulic cylinder 40 is reversed by pressing the hydraulic pressure release lever 60 to move it to the side of the link 30 and fixed, the elevator 20 is the folding operation of the link 30 gradually. As it is made, it descends to the upper side of the base body 10, and in the lowered state, it is possible to move to the ground through the inclined footrest 14.

That is, unlike the existing wheelchair lift, the lift according to the present invention enters the direction the disabled person proceeds in a state in which the lift is first set close to the structure, and can be carried out after ascending or descending through the elevator, so that the disabled can be boarded. Compared to the operation method of moving the lift and adjusting the number of elevators to position the lift on the structure, handling is simple, as well as being able to stably fix the raised elevator to the height of the structure by changing the length of the fixing member. It becomes possible to realize safer lifting.

As described above, the present invention has been described with specific matters such as specific components and limited embodiments and drawings, but these are only provided to help a more general understanding of the present invention, and the present invention is not limited to the above embodiments. , various modifications and variations are possible from these descriptions by those of ordinary skill in the art to which the present invention pertains.
