Abstract

The present invention provides a wheelchair auxiliary table that is easy to attach and detach, can be used easily and can accommodate a plurality of seat widths, because a user can freely shop while carrying a wheelchair by himself with a shopping basket. The present invention has a simple configuration of a table plate 21, a support rod 22 attached to a wheelchair, and a fixing metal fitting thereof. In consideration of weight reduction, a single bar is bent and formed into functional portions. Since the support rod 22 can be attached so that the end portion bent upward at a right angle is hooked on the armrest 11 of the wheelchair, an auxiliary table that can be easily attached and detached is realized. By fixing the support rod 22 to the table plate 21 with metal fittings at one place on each of the left and right sides, the distance from the fixing position to the rear end of the support rod 22 can be extended so that it can be widened and narrowed left and right within the elastic range. It becomes possible to correspond to multiple seat widths. [Selection] Figure 1

Description

  The present invention relates to a wheelchair auxiliary table whose main purpose is to place a shopping basket when a wheelchair user performs shopping while operating the wheelchair himself.

  When a wheelchair user himself / herself makes a purchase while operating the wheelchair, there is a method of shopping by connecting a wheelchair-only shopping cart to the front of the wheelchair. As a result, the overall size becomes long, and it cannot be used in a narrow place, or it is not necessarily convenient because it can be used while taking care of other shoppers. Therefore, in order to move freely even in a small place without worrying about other customers, I think that a place to put a shopping basket in the wheelchair and a space that does not hinder operation are necessary, but wheelchair users themselves by methods other than the above It is almost impossible to see a person who is shopping freely with a shopping basket, and the wheelchair user himself has no auxiliary table device that can be easily installed in the wheelchair. I think it is.

  The place where the user puts the shopping basket in the wheelchair operated by the user himself / herself is within the reach of the armrest or in front of the armrest, but the wheelchair operation space becomes narrow at the armrest position. A table or table with a shopping basket placed in front of the armrest at a height has been devised. (Patent Document 1)

  Further, a method for placing a pedestal for placing a shopping basket on the user's own thigh (Patent Document 2) and a method for suspending a basket holder for placing a shopping basket in front of the knee (Patent Document 3) have been devised.

  About the method of attaching a stand etc. to a wheelchair front, in addition to the method of connecting with the wheelchair body using the connecting belt described in Patent Document 3, the folding table on which the shopping basket described in Patent Document 1 is placed is unfolded from the folded state. Thus, a method has been proposed in which the U-shaped portion at the tip of the cantilever is fitted into the armrest and fixed in a state in which the base protrudes in front of the armrest.

  Similarly, as a method of projecting the table in front of the armrest and supporting it with a cantilever, hit the bracket from the bottom behind the armrest to prevent the end of the cantilever from lifting, and the front of the armrest hits the bracket from the top A method has been devised to support the table load. (Patent Document 4)

  However, in the method described in Patent Document 1, there is a high possibility that the weight will be heavy when considering the strength and durability because the number of components and the hinge portion constituting the base are large and complicated.

  According to the method described in Patent Document 2, it is not attached to a wheelchair, but a shopping basket is placed on a table on a wheelchair user's knee to operate the wheelchair, and the table itself is unstable.

  In the method described in Patent Document 3, it is assumed that the belt for connecting the heel holder to the wheelchair is attached by a person other than the wheelchair user.

  In Patent Document 4, the height at which the shopping basket is placed is higher than the height of the armrest or the height of the armrest, and it is difficult to look inside the shopping basket. In addition, the applicable size of wheelchairs does not support multiple seat widths.

  An auxiliary table with a simple structure that is light, durable, and easy to attach and detach, so that you can place your shopping basket on a wheelchair and operate the wheelchair yourself without helping caregivers. In consideration of the ease of peeking inside the shopping basket placed on the table and the ease of operation in the wheelchair, and the ease of use, it is also necessary to accommodate multiple seat widths.

  The auxiliary table used by being attached to the wheelchair of the present invention can be lightened as a whole by a simple configuration of the table plate, the support rod, and the bracket for fixing the support rod to the table plate. The support rod for installing the table board on the wheelchair is formed by bending a single bar material to give each part a function. The function makes the table board lower than the armrest and forward of the armrest. In addition to securing an operation space in the wheelchair, it is easy to look into the shopping basket. In addition, by bending the extreme end of the support rod upward at a right angle, the auxiliary table can be set so as to be hooked on the armrest and cannot be easily removed when a load is applied to the table. By making the fixing position of the support rod by the bracket the front of the table and increasing the length from the fixed portion to the rod end, the swinging width of the rod to the left and right within the elastic deformation range is increased. The present invention solves the above-mentioned problems such as being able to cope with the seat width.

  The wheelchair user can hold the left and right support rods with both hands, set the distance between the support rods narrower than the seat width, and tilt it from the front to the back, insert it inside the armrest of the wheelchair and lower the table board. , Wheelchair users will be able to shop more easily.

  The present invention has a very simple configuration including only a support rod for mounting on a table plate and a wheelchair and a fixing bracket thereof. The support rod made of a single bar is light and easy to attach and detach, and has a lot of functions in forming by bending. Furthermore, by making it possible to handle multiple seat widths for the applicable size of the wheelchair, you can set up your own table without using the caregiver's hand, and you can operate your own wheelchair with a shopping basket. it can. In other words, it is possible to realize easy and free shopping for the wheelchair user himself / herself. In forming the support rod by bending, a shopping basket stopper is formed at the center of the bar, and from there, the parts that function as the table plate installation part, table plate load holding part, and support rod detachment prevention part are created. It is done. There is a portion bent at a right angle upward at the end of the rod of the support rod detachment prevention portion, and when the table is installed on the wheelchair, this portion is attached so as to be hooked on the armrest of the wheelchair. Since the entire support rod is formed by processing a single bar, the bracket can be fixed to the table at one place on each of the left and right sides. By extending the length to the end, it can be easily widened and narrowed to the left and right within the elastic range of the support rod. It can be attached to the armrest by the shape of the end of the support rod detachment prevention part, and the left and right support rods can be expanded and narrowed within the range of elastic deformation, making it easy to attach and detach the device. In addition, it is possible to handle a plurality of seat widths. Embodiments of the present invention will be described below with reference to the accompanying drawings.

  FIG. 1 shows a state in which the present invention is installed on a wheelchair. The main parts of the present invention have a very simple structure consisting of only the table plate 21, the support rod 22 and the support rod fixing bracket, but the installation method is also to be hooked on the armrest 11 and the pipe frame 12 of the wheelchair. The wheelchair user can fully handle it.

  FIG. 2 is an exploded view of the present invention. It consists of a table plate 21, a support rod 22, an upper bracket 23 for fixing a support rod, a lower bracket 24 for fixing a support rod, a bolt 25, and a nut 26. The support rod 22 has a plurality of functions by molding by bending. It is

  FIG. 3 is a detailed view of the wheelchair armrest 11 with the present invention attached. The support rod 22 made of one bar with a table plate 21, support rod 22, support rod fixing upper metal fitting 23, support rod fixing lower metal fitting 24, bolt 25, and nut 26 is a shopping basket stopper. Bending with a role is performed toward each rod end with the portion 22a at the center. First, the bar bent diagonally rearward from the shopping basket stopper portion 22a processed to about half the width of the table plate 21 is bent straight rearward at a width that fits within the width of the wheelchair seat. It is done. This shape is due to the fact that the table plate 21 is stably fixed and the amount of the bar is reduced as much as possible to reduce the weight. The bar bent straight rearward secures the depth of the table plate 21 and becomes the table plate installation portion 22b. From there, it is bent upward at an angle of about 30 degrees, and this angle and length determine how far the table plate 21 is lowered from the armrest 11 of the wheelchair. When the angle and length are determined and reach the armrest 11, the bar is bent into a U shape toward the outside of the armrest 11, becomes a table plate load holding portion 22 c, and rides on the armrest 11 to shop on the table plate 21. It will be a place to receive the load of firewood. Since the bar has been bent into a U-shape, it is bent at a right angle when it returns to the inside of the armrest 11 again, bent backward and downward along the inside of the armrest 11, and then the wheelchair for fixing the armrest 11 It is bent at a right angle so as to pass under the pipe frame 12 and to the side of the wheelchair, and at the outside of the armrest 11, the end of the bar is bent at a right angle toward the top, and the support rod detachment prevention portion 22d. It becomes. When the armrest 11 and the pipe frame 12 are viewed from the front, the support rod 22 is in a state of completely wrapping the armrest 11 and the pipe frame 12, so that the support rod 22 is not easily detached. Further, the left and right support rods 22 extending from the table plate 21 have a length from the fixed portion to the rod end as long as possible to increase the width of the rod to the left and right within the range of elastic deformation. It becomes possible to correspond to the seat width.

  FIG. 4 is a state diagram when corresponding to a plurality of seat widths. (A) is the installation situation of this invention produced according to the wheelchair of the standard seat width Wm. The support rod 22 fixed to the table plate 21 at two fixing brackets is not particularly deformed. (B) is a situation where the present invention is installed in a wheelchair having a narrower seat width Ws than (a). The support rod 22 is pushed inward (Li1, Li2) by the armrest 11, and the support rod 22 on the portion on which the table plate 21 is placed is bent inward within the range of elastic deformation. In this state, the endmost part of the support rod 22 tends to go further inward, but the end bent upward at a right angle is caught on the outside of the armrest 11, and the wheelchair has a seat width Ws smaller than the seat width Wm. But it can be installed. (C) is a situation where the present invention is installed in a wheelchair having a wider seat width Wl than (a). Each of the support rods 22 protruding from the table plate 21 is expanded in the outward (Lo1, Lo2) direction within the range of elastic deformation, and the outermost portion of the armrest 11 is hooked with the end portion bent vertically upward of the support rod 22. The table plate load holding portion 22c is installed on the armrest 11.

  FIG. 5 is a wheelchair installation method diagram. The end of the support rod 22 that is inserted between the left and right armrests 11 and bent at a right angle is hooked to the outside of the armrest 11 under the pipe frame 12 by spreading or squeezing it. The main body of the present invention is installed.

  FIG. 6 is a comparison diagram of how the shopping basket looks according to the installation height of the table board. (A) is a case where a table board gets on the armrest 11. FIG. (B) is a case where a table or a mounting tool is the same height as the armrest 11. (C) is the case of the present invention. (D) is a view when the inclination angle of the support rod 22 extending from the table plate load holding portion 22c of the present invention to the portion on which the table plate 21 is placed is increased. In this case, the table plate is Since there is a possibility of hitting the knee, it is necessary to attach the cushion mat 27 to the lower surface of the table plate 21 in advance. (E) and (f) show that the appearance changes depending on where the present invention is set before and after the armrest 11. If you set it closer to your body, it is easier to look inside the shopping basket, but the operation space is smaller. As a result of the above, it is easier to look inside the shopping basket by lowering the height of the table board than the armrest 11, but this is limited to the height of the knee. It is necessary to bring the installation position on the armrest 11 of the present invention closer to the body within a range where an operation space can be secured, and it can be seen that this is possible in the present invention.
