Description

Side cover for wheelchair {SIDE COVER FOR WHEELCHAIR}

The present invention relates to a side cover for a wheelchair, and more specifically, it is mounted on a side frame with an armrest, covers the wheels, and performs the function of blocking foreign substances from entering the seat through the wheels when driving from the outside, and is worn by the user. This relates to the provision of a side cover for a wheel chair that prevents clothing from being contaminated by being connected to the wheels.

A wheelchair is a type of medical device that helps the physically disabled, patients, and the elderly and those with limited mobility to move around easily. These wheelchairs are either manually driven by the user or pushed by a guardian, or by driving the wheels using an electric device. It is classified into electric type for driving.

Various types of wheelchairs as described above have been developed and provided, and the configuration of a representative example of the manual type is as follows through Figure 1.

A typical wheelchair 100 is equipped to be foldable and has a backrest 101 and a handle 102 at the rear to make it convenient for the user to sit, and a seat 103 and footrest 104 for seating at the center and front. The branches are provided with a main frame 105 in the form of a step.

On both sides of the main frame 105, a side frame 107 is coupled with an armrest 106 at the top and can be reclined backward, and a driving ring 108 is installed on both sides of the main frame 105. The main wheel 109 is installed.

Auxiliary wheels 110 are installed in front of the main wheel 109 to enable the wheelchair 100 to move, and brakes 111 are installed on both sides of the main frame 105 to stop the moving wheelchair 100. This is the configuration in which it is installed.

Of course, there are cases where the side frame with the armrest is integrated with the main frame without being separated, and there are cases where the main frame is provided so that it can be folded in the width direction, and various overall shapes and shapes are presented.

In most cases, only an armrest that can support the user's arms is mounted on the upper part of the side frame and the lower part is left open, or a thin plate-shaped member is attached for the purpose of enhancing the appearance because there is too much open space. There are cases.

The configuration of a wheelchair to which prior art is applied is examined through patent literature as follows.

Patent Document 1 states that a push assist device, which is a mobility aid, includes two straight bars spaced apart to face each other side by side, and a grippable curved bar connecting the straight bars, and the wheelchair is provided with side guards on both sides of the seat. , The side guard is characterized in that it constitutes a fixed side guard fixedly installed on the rear left and right sides of the seat, respectively, and a detachable side guard in which the aforementioned push assist is detachably coupled to the front left and right sides of the seat, respectively.

Patent Registration No. 10 - 1384475 - 0000

doesn't exist.

In the case of the above patent document, the key point is to have a removable side guard on the side of the wheelchair that can be used as a mobility aid, but this is technical content unrelated to the function of covering the side part of the wheelchair.

In the case of a wheelchair to which the above-described conventional technology is applied, the side frame is open or only partially blocked, so ventilation may be easy when users are seated, but the following problems occur.

In the prior art, the side cover, which is further mounted on the side frame, is installed by bending a metal plate and using rivets, bolts, and nuts, so it is difficult to give it a beautiful appearance, and because it is made of metal, it increases the overall weight of the wheelchair. Therefore, it does not fit the trend of becoming lighter day by day and is causing difficulties for users in operating the wheelchair.

Since the side cover is simply fixed in the form of a boundary between the main wheel and the main frame, it does not actually perform the function of covering the main wheel, so when the user wants to drive the wheelchair by holding the integrated driving ring, it must be covered with the sleeve of the user's clothes. This prevents the area from touching the main wheel and contaminating the clothes.

In addition, while the user holds on to the drive ring and moves the wheelchair, the user's body, such as the user's arms, wrists, and the back of the hand, frequently interferes with the main wheel. In addition, the skin is damaged during the process of contact with the main wheel and the body, and in severe cases, the body is damaged. The risk of a safety accident caused by being caught between the main frame, side frame, side cover, and main wheel cannot be ruled out.

Even if the side cover is installed on the side frame, it is fixed at a certain distance from the seat to discharge foreign substances, improve ventilation, and provide ease of cleaning, so there is no gap between the main frame, side frame, and side cover. Through this, the user's clothes are exposed and come into contact with the main wheel, raising the risk of contamination and damage.

As described above, in the case of a site cover mounted on a wheelchair to which the prior art is applied, it is made of a simple plate-shaped member, so it is difficult to perform its function, spoils the appearance, increases the weight of the wheelchair, and reduces the quality of the wheelchair with the expectation of functional improvement. There are many problems arising, including the fact that it is realistically difficult to contribute to the improvement.

Accordingly, the present invention was invented to solve the above problems, and has a staircase shape with a backrest 101 and a handle 102 at the rear and a seat 103 and a footrest 104 for seating at the center and front. A main frame 105, a side frame 107 that has an armrest 106 at the top and is coupled to both sides of the main frame 105 so that it can recline rearward, and a driving ring on both sides of the main frame 105.

A typical wheelchair 100 is equipped to be foldable and has a backrest 101 and a handle 102 at the rear to make it convenient for the user to sit, and a seat 103 and footrest 104 for seating at the center and front. The branches are provided with a main frame 105 in the form of a step.

On both sides of the main frame 105, a side frame 107 is coupled with an armrest 106 at the top and can be reclined backward, and a driving ring 108 is installed on both sides of the main frame 105. The main wheel 109 is installed.

Auxiliary wheels 110 are installed in front of the main wheel 109 to enable the wheelchair 100 to move, and brakes 111 are installed on both sides of the main frame 105 to stop the moving wheelchair 100. This is the configuration in which it is installed.

In the present design, while blocking contaminants from flowing toward the seat 103 through the main wheel 109 in the side frame 107, contamination or safety accidents occur when the user's clothing or body comes into contact with the main wheel 109. It is characterized by additionally mounting a side cover 120 to prevent it from happening.

The side cover 120 is provided with a plate-shaped cover body 121 that is injection molded from a plastic material, and an inclined bar 122 is connected to the upper part of the side frame 107 on the front upper part of the cover body 121. ) A forward inclined portion 123 is formed to be downwardly directed forward, and a front end 124 is formed to be directed downward at the tip of the forward inclined portion 123.

A rearward inclined portion 125 is formed on the rear upper part of the cover body 121 downwardly to the rear, and a rear end 126 is formed at the rear end of the rearward inclined portion 125, which is downwardly inclined, and each corner portion. It forms a round shape to prevent safety accidents such as stabbing during handling or use.

The forward inclined portion 123 and the front end 124 are in close contact with the inner surface of the side frame 107, and a plurality of front fixing holes 128 are formed so that they can be fixed with fixing means 127 such as screws.

A plurality of rear fixing holes 129 are formed on the inner surface of the rear end 126 so as to be in close contact with the outer surface of the side frame 107 and fixed with fixing means 127, and the rear fixing holes 129 In the inner position of the cover body 121, a correction means 130 is further formed to correct the longitudinal deviation of the front and rear sides of the side frame 107.

The correction means 130 is a deviation ( G), which is intended to overcome this deviation (G) so that the side cover 120 can maintain a straight line.

The correction means 130 is formed by protruding a correction protrusion 133 inward as much as the deviation G between the front longitudinal bar 131 and the rear longitudinal bar 132, and the axial center of the correction protrusion 133 is An entry hole 134 is formed so that the fixing means 127 can enter, and the inner end of the compensation protrusion 133 has a shape identical to the outer diameter of the rear longitudinal bar 132 to increase adhesion to the rear longitudinal bar 132. It is constructed by forming a concave elevation surface (135).

At the upper rear position of the cover body 121, an arc-shaped wheel cover 140 is provided to cover the inner side (seat direction) and upper surface of the main wheel 109 to prevent foreign substances, etc. from entering or scattering in the seat direction. is formed to protrude in the outward direction.

The wheel cover 140 is formed from the upper middle position of the cover body 121 to the rearward inclined portion 125. If it is formed to extend further rearward than this, it is used during the reclining side frame 107. This is because complete reclining is not achieved due to interference with the wheel 107.

The wheel cover 140 extends rearward when the side frame 107 is not reclining to prevent the inflow and scattering of foreign substances generated by the main wheels 107 when the wheelchair 100 is driven, and extends forward when reclining. An auxiliary cover 145 is further provided so that it can be folded to exclude interference.

The auxiliary cover 145 forms a sliding rail 146 integrally with the wheel cover 140 in the front and rear directions, and a plate-shaped cover blade 147 is coupled to the sliding rail 146 to form a wheel cover. It extends to the rear of (140) and can be stored.

It would be desirable to form a guide rail 148 on the cover body 121 at the rear of the wheel cover 140 to prevent the fluidity of the cover blade 147 extending rearward and maintain a stable state, and the cover A stopper that also serves as a handle may be integrally formed on the front and rear sides of the blade 147 to prevent excessive extraction or insertion.

The state of use of the side cover 120 for a wheelchair to which the technology of the present invention is applied as described above is as follows.

The side cover 120 is mounted on the side frame 107 constituting the wheelchair 100, and the front end 124 of the cover body 121 is tightly fixed to the inner surface on the front of the side frame 107. , At the rear of the side frame 107, the rear end 126 of the cover body 121 is fixed in close contact with the outer surface.

When fixing the rear end 126, the rear longitudinal bar 132 moves further in the seat direction compared to the front longitudinal bar 131 constituting the side frame 107, resulting in a deviation (G), which is caused by the cover body ( The side cover 120 is adjusted by the correction means 130 formed inside the rear end 126 of 121 to maintain a straight line.

In this state, the wheel cover 140, which is integrally formed with the cover body 121 and protrudes outward, is located on the upper side of the main wheel 109, so that even when the wheelchair 100 is driven, it is driven by the running of the main wheel 109. It prevents foreign substances or contaminants on the wheel 109 from scattering and blocks them from flowing toward the seat.

When driving the wheelchair 100, the auxiliary cover 145, which is further provided with the wheel cover 140, is pulled out to the rear to block the upper side of the main wheel 109 at the rear position, which is not covered by the wheel cover 140. It is possible to fundamentally block foreign substances and contaminants from flowing into the seat direction.

In addition, when the wheelchair 100 stops moving and the user wants to recline the side frame 107 rearward for boarding or disembarking, the auxiliary cover 145 that was pulled out to the rear is returned to its original position during the reclining process. This can be done to prevent the auxiliary cover 145 from interfering with the main wheel 109.
