The present invention relates to an armrest assembly for a wheelchair, and more particularly, to an armrest provided to facilitate folding and separation and height and height adjustment by improving armrests provided on both sides of a frame.

Wheelchairs are one of the medical devices that help patients with physical disabilities and the elderly who are inconvenient to move easily. These wheelchairs are manual type which drives wheels by manpower and electric type which drives wheels using electric device. And the like.

Such a wheelchair is provided with main wheels on both sides of the frame constituting the wheelchair, and auxiliary wheels are installed on both ends of the frame to provide ease of movement.

As shown in FIG. 1, the wheelchair 100 is provided to be folded and has a backrest 101 and a handle 102 at the rear for convenient seating, and a seat 103 for seating at the center and front. It is provided with a left and right frame 104, 105 of the roughly stepped shape.

On both sides of the left and right frames 104 and 105, the main wheel 107 is equipped with a driving ring, and the auxiliary wheel 108 is installed in front of the main wheel 107 so that the wheelchair 100 can move. The brakes 109 are provided at both sides of the left and right frames 104 and 105 to stop the wheelchair 100 in motion.

Above the left and right frames 104 and 105, the armrest assembly 115 is provided to keep the arms of wheelchair users in a comfortable state.

Since the armrest assembly to which the prior art is applied has a shape that is firmly fixed to the upper left and right frames, it is impossible to fold or separate the entire armrest assembly.

For this reason, when the user wants to get out of the wheelchair, it causes considerable inconvenience. If the user wants to get in the wheelchair or get out of the wheelchair, the armrest causes the jam to be easily lifted. It is impossible to get off.

In other words, in the simple step of getting on and off the wheelchair, the jamming occurs due to the armrest, as well as the movement from the bed or the chair to the wheelchair, or the wheelchair to the bed or the chair, etc.

In particular, most wheelchairs are used by the elderly, the elderly, or people with physical disabilities, so it is easy to check how uncomfortable the constraints caused by the footrest.

Therefore, the present invention is designed to solve the problems as described above, by adjusting the height and height of the armrest assembly to improve the convenience of the user, as well as by configuring the armrest assembly to open and close the rear. The purpose is to provide ease of getting in and out of the wheelchair.

Hereinafter, with reference to the accompanying drawings will be described the configuration and operation of the present invention for achieving the above object.

Conventional wheelchair 100, as shown in Figure 1, is provided to be folded and has a backrest 101 and a handle 102 at the rear to facilitate the user sitting, seat in the center and front ( And left and right frames 104 and 105 in the form of roughly stepped stairs 103.

On both sides of the left and right frames 104 and 105, the main wheel 107 is mounted with a driving ring, and the auxiliary wheel 108 is installed in front of the main wheel 107 so that the wheelchair 100 can move. In addition, both sides of the left and right frames 104 and 105 are provided with brakes 109 for stopping the wheelchair 100 in motion.

Above the left and right frames 104 and 105, the armrest assembly 115 is provided to keep the arms of wheelchair users in a comfortable state.

In the present invention, the armrest assembly 115 is provided with a height and a height adjustable while allowing the left and right frames 104 and 105 to be opened and closed rearward, so that the armrest assembly 115 can be easily lifted and unloaded from the wheelchair. It is characterized in that to maintain a comfortable posture.

형상으로 된 암레스트프레임(118)을 구비한다.To this end, the armrest assembly 115 is separated from the left and right frames 104 and 105 and is composed of vertical bars 116 and horizontal bars 117 on both sides.

An armrest frame 118 is formed in a shape.

The upper part of the vertical bar 116 of the armrest frame 118 to cover the lower body of the user seated via the side plate 119, the rear lower portion of the armrest frame 118 is left, right The frame 104, 105 and the hinge 120 is coupled to open and close freely in the rear.

The front lower portion of the armrest frame 118 is provided with a locking means 121 with respect to the left and right frames 104 and 105 to prevent unnecessary fluidity of the armrest frame 118, and the armrest frame ( The upper part of the 118 is provided with an armrest 122 that can adjust the height, height.

The locking means 121 has intermittent pins 125 provided on the left and right frames 104 and 105 in which the front vertical bars 116 of the armrest frame 118 are positioned, and the intermittent pins 125 are positioned. A pinhole 126 is formed in the vertical bar 116, and an interruption plate 128 having an interruption hole 127 is formed on the outside of the interruption hole 126 to lock the head of the interruption pin 125. Equipped.

One side of the intermittent plate 128 is intermittent with the screw 130 through the spring 129 to hold the intermittent plate 128 and pulled outward to release and release the intermittent plate 128 to be interrupted by the pressing force of the spring 129.

The armrest 122 has a cushion 130 on the upper side of the holding bar 131 is provided horizontally and the control bar 132 is fixed in the longitudinal direction in the middle of the holding bar 131.

The adjustment bar 132 of the armrest 122 is inserted into the control hole 136 formed in the control tube 135 is fixed to the middle of the armrest frame 118, the control bar 132 a plurality of Four adjustment holes 137 are formed, and the adjustment hole 136 is provided with a control pin 138.

Inside the control hole 136 has a built-in intermittent plate 139 having elasticity to prevent the flow of the adjustment bar 132, the intermittent plate 139 is coupled to the outside of the control tube 135 It is configured to be adjusted by the intermittent bolt 140.

Armrest assembly 115 for a wheelchair of the present invention as described above,

Looking at the initial state as a state using the wheelchair 100, the armrest assembly 115 is in a locked state so as not to flow to both sides of the left and right frames (104, 105).

That is, the intermittent pins 128 provided at the front lower portion of the armrest frame 118 fixed to the hinge 120 at the rear of the left and right frames 104 and 105 are provided at the left and right frames 104 and 105. 125, the armrest frame 118 is not opened to the rear because it is in a dry state.

In this state, the height and height of the armrest 122 provided above the armrest frame 118 may be adjusted according to the user's body to maintain a comfortable posture.

Adjusting the height of the armrest 122, the adjustment bar 132 of the armrest 122 is inserted into the control hole 136 is formed in the control tube 135 provided in the armrest frame 118 After moving in the up and down direction, the adjusting pin 138 is inserted into the adjusting hole 137 formed in the adjusting bar 137 to adjust.

And, the flow of the adjustment bar 132 is tightened by the intermittent bolt 140 to press the intermittent plate 139 embedded in the control tube 135 to control the intermittent plate 139 and the control bar 132. By removing the play between the holes 136 will not flow.

In addition, in the case where the armrest assembly 115 is opened to the rear to get on or off the wheelchair 100, the hinge means is released and then the rear side of the armrest frame 118 is grasped and rotated backward. By opening and rotating around the center (120), it is possible to easily get on and off.

Looking at the operation of the lock means 121, in the lock state, the head of the control pin 125 inserted into the pin hole 126 formed in the vertical bar 116 is interrupted by the control hole 127 of the control plate 128 In the state of being in the state of release, the intermittent plate 128 is lifted by the intermittent hole 127 to be able to rotate the armrest frame 118 by leaving the head of the intermittent pin 125.

Then, when the pivoted armrest frame 118 is brought back to its original position, the intermittent plate 128 returned to its original state by the spring 129 naturally locks while accommodating the head of the intermittent pin 125. Will be done.

The present invention as described above is to adjust the height and height of the armrest assembly to improve the convenience of the user, as well as to configure the armrest assembly to open and close the rear to provide ease of getting on and off the wheelchair. It is devised to have various effects such as can.
