Folding type wheelchair lift {FOLDING TYPE LIFT FOR WHEELCHAIR}

The present invention relates to a folding-type wheelchair lift, and more particularly, when a wheelchair user enters and exits a building, the lift is moved, portability, and storage in constructing a wheelchair lift that allows the wheelchair user to move up and down with the wheelchair to move the position. It relates to a folding-type wheelchair lift that implements an operating structure for increasing safety and convenience in use while securing the structure.

In general, a wheelchair is a moving device in the form of a chair in which wheels are installed so that a person with disabilities can move while sitting.

Wheelchairs are designed to allow users to drive by manipulating wheel handles and brakes.In recent years, electric wheelchairs that electronically control all driving motions such as steering and speed by mounting electric motors, or robot wheelchairs with artificial intelligence technology have been developed and used. have.

Wheelchairs can be driven on flat ground or on low-angled slopes, but there are restrictions on the movement of the wheelchair when entering buildings or places with high steps or stairs. Although the law mandates the installation of ramps for wheelchair users in some buildings, in fact, it is difficult to find in most places except government offices and hospitals, and wheelchair lifts are also installed in some places where it is difficult to install ramps. .

On the other hand, looking at the configuration of a conventional wheelchair lift through a known technology, as an example, Korea Open Utility Model No. 20-1998-0002817 includes an elevating wheelchair moving device body installed in a recessed type on one side in front of the entrance of a public building. Wow, a support plate mounted on the upper part of the main body, a safety handle and an operation switch installed on one side of the surface of the support plate, a hydraulic cylinder and power device provided in the main body, a guide rod support member installed inside the main body, and integral with the support plate It constitutes a built-in elevating wheelchair mobile device having a guide rod for support that is installed under the furnace and slides.

As another example, Korean Patent Registration No. 10-0375129 discloses a car with a door open and closed at the front, a rope having one end coupled to the outer surface of the car and the other end coupled to a hydraulic cylinder, and the tension generated in the rope. The sheave rotates to one side and the other side by means of a hydraulic cylinder installed with an upper end coupled to the shaft of the sheave and a lower end fixed to the ground, and a hydraulic pressure controlling the elevating speed of the car by supplying and discharging the hydraulic pressure to the hydraulic cylinder in a certain amount. It constitutes an elevator-type wheelchair moving device including a control unit and a lowering control valve for manually operating and discharging hydraulic pressure supplied to the hydraulic cylinder through the hydraulic control unit.

As another example, Korean Patent Registration No. 10-1083365 includes a board for riding a wheelchair, an exit door provided on the board, and a protection guide fastened to the board and the board to have a certain height. The table and two pairs of X-shaped frames that can rotate at the intersection are provided at regular intervals, the guide frame that connects and supports the lower frame and the upper frame, and the lift table is raised and lowered using oil or pneumatic cylinders or drive motors. It constitutes a wheelchair elevating device including a moving lift device.

Korea Open Utility Model 20-1998-0002817 (1998.03.30) Korean Patent Registration No. 10- 0375129 (2003.03.08) Korean Patent Registration No. 10-1083365 (2011.11.14) Korean Patent Registration No. 10-1020722 (2011.03.09)

As described above, in the process of ascending the platform 170, the first lamp 172 has the first folding roller 195 of the first swing bar 197 hinged to the first folding fixing bar 193. It moves upward along the straight portion of the first path 153 formed in the folding portion 191, and changes to a state in which it is gradually folded from the lift table 171 according to the posture and angle of engagement with the upper curved portion.

Conversely, the second lamp 173 has a second path in which the second folding roller 196 of the second swing bar 198 hinged with the second folding fixing bar 194 is formed in the third folding part 192 It moves upward along the straight portion of 154 and is provided as a ramp by gradually changing to a state in which it is gradually deployed according to the attitude and angle of the coupling with the upper curved portion.

8 shows a state in which the platform 170 is raised to a set height in the wheelchair lift of the present invention.

When the ascent of the platform 170 is completed as described above, the wheelchair user can get off the elevator table 171 through the second lamp 173 and move to the desired place, and when moving from a high place to a low place You may do this in reverse.

On the other hand, when the folding-type wheelchair lift according to the present invention is not used, or is to be carried or stored, the size of the platform 170 may be folded together to minimize the size.

9 to 10 show a state in which the entire configuration of the platform 170 of the wheelchair lift according to the present invention is folded.

First, as shown in Fig. 1, in a state in which the platform 170 is deployed parallel to the ground in a lowered state, the safety fence 174 attached to the lifting table 171 is removed and the lifting table 171 ).

In addition, the first folding roller 195 and the second folding roller 196 provided in the first swing bar 197 and the second swing bar 198 are used as a first folding guide bar 151 and a second folding guide. It is removed from the bar 152 to separate the second folding part 191 and the third folding part 192.

In such a state, the platform 170 is pulled away from the cover 160 so that the horizontal support 181 of the first folding part 180 is separated from the horizontal support groove 141 of the folding hinge bar 140 Let it. Since the folding hinge hole 142 is provided in a long hole shape, the position of the folding hinge pin 182 is moved along the length direction of the long hole.

From the folding hinge pin 182 as a starting point, the entire platform 170 is folded toward the cover 160, and the second folding part 191 from the first folding guide bar 151 and the second folding guide bar 152 And the first lamp 172 and the second lamp 173 in a state in which the third folding part 192 is separated are folded toward the lifting table 171. In addition, the extension frame 112 provided to extend the platform 170 toward the lower side of the base frame 110 is accommodated in the beam frame to reduce the overall size of the lift.

In order to easily move the folded lift as described above, a predetermined handle 113 may be combined and used on the rear upper side of the base frame 110.

The folding-type wheelchair lift according to the present invention as described above provides a folding-type wheelchair lift having a simplified structure that is easy to move, carry, and store differently from the conventional embedded or installed wheelchair lift.

In particular, the present invention greatly reduces the size of the entire lift through a configuration that allows the entire platform to be easily folded as described above, so that it can be easily carried and stored in a vehicle, etc., and it is easy to move to a narrow passage or place, and lift and fold operation. It is characterized by a very simple set of structures to implement.

Therefore, a wheelchair user can conveniently carry a folding-type wheelchair lift according to the present invention along with a wheelchair in the vehicle to conveniently use the wheelchair lift at a desired location, so that the wheelchair user can move in most places where a ramp or an installation type lift is not installed. It derives various effects, such as being able to solve many of the problems that had many limitations.
