Description

  The present invention relates to a wheelchair scale for measuring the weight of a wheelchair user.

  To measure the weight of persons with disabilities who use wheelchairs, place the wheelchair on the wheelchair scale in advance, measure the weight, and then measure the total weight of the wheelchair and body weight while riding on the wheelchair. Done by asking. Hospitals and disabled facilities are equipped with wheelchair scales that allow wheelchairs to be placed. A wheelchair scale requires a large area for mounting various wheelchairs, and the entire weighing platform is made of a rigid body to measure the total weight and weight of a wheelchair. It is made more robust. As a result, the current situation is very heavy and large. The wheelchair scale currently on the market is approximately 80 cm × 90 cm in size and approximately 20-30 kg in weight. Therefore, a large space is required to install or store a wheelchair scale in a hospital or facility. Moreover, since it is large and heavy, it is difficult to move and carry, and it is dangerous and expensive.

  On the other hand, a lightweight and inexpensive home-use wheelchair weight scale has been devised which uses aluminum as a member and a home scale. (Refer to Patent Document 1) Although this wheelchair scale is lightweight and inexpensive, it cannot be folded, so the size is the same as that currently used in the facility, requires a large storage space, and is easy to carry. Absent. In addition, since there is a step at the entrance of the weighing platform, there is a safety problem that the other end is lifted when the wheelchair enters the weighing platform, which is not suitable for use in hospitals or facilities from the viewpoint of safety.

  SUMMARY OF THE INVENTION The present invention solves the above-mentioned problems of the conventional system, and is intended to provide a wheelchair weight scale that can be used in hospitals and facilities because it is small and light, easy to carry, requires little storage space.

  The first solving means in the present invention includes a pair of vehicle mounts for mounting the left and right wheels of the wheelchair, an extendable connection means for connecting the pair of vehicle mounts, and a weight attached to each vehicle mount. It is composed of a plurality of sensors for measurement, and the extendable connecting means is lighter than a pair of vehicle-mounted bases and can be folded.

  The second solving means is to connect the extendable connecting means to be able to bend the pair of support members that are hardly deformed, the connecting portion that connects the two support members so that they can be bent, and the other end of the support member and the vehicle-mounted base. This is a structure composed of connecting parts.

  A third solution is that the portion where the rear wheel is located is made stronger in structure or material than the portion where the front wheel of the wheelchair of the vehicle-mounted base is located.

  The fourth solving means is that the portion where the rear wheel of the vehicle-mounted base is located has a concave shape.

  A fifth solution is to provide a progress preventing mechanism in the vehicle-mounted table so that the wheelchair cannot get down to the front of the vehicle-mounted table.

  A sixth solving means is that there is a slope at least a part of which is in contact with the floor at the entry portion of the vehicle mount, and one end of the slope is coupled to the vehicle mount in a bendable manner.

  The effect of the first solving means of the present invention is that the connection means that is lighter than the vehicle-mounted base can be used, so that the total weight is light and can be folded, and it is easy to carry and requires a small storage space. It is.

  The effect of the second solving means is that the width when folded can be reduced to the width of the vehicle-mounted base.

  The effect of the third solution means that the overall weight can be reduced by increasing the strength of the rear wheel portion of the wheelchair that requires the most weight and reducing the strength of the other portions.

  The effect of the fourth solution is that, by making the portion where the rear wheel of the wheelchair is located concave, the position of the most heavy rear wheel is always at a predetermined position, so that stable measurement with high reproducibility can be performed. It is.

  The effect of the fifth solution is that by limiting the entry / exit of the wheelchair in one direction, the vehicle-mounted base can be made to have a structure corresponding to a heavy rear wheel part and a light front wheel part, and a slope is provided only on one side. It is only necessary.

  The effect of the sixth solving means is that the wheelchair can be smoothly boarded and exited due to the slope, and the slope can be folded inward to facilitate downsizing and carrying.

It is a figure which shows the shape and structure of the weight scale for wheelchairs of this invention. It is a figure which shows the folding method of the scale for wheelchairs of this invention. It is a figure which shows the folded state of the weight scale for wheelchairs of this invention. It is an enlarged view of the slope of the wheel scale for wheelchairs of this invention, a back reinforcement board, and a hollow. It is a figure which shows the modification of a concave hollow.

  Hereinafter, embodiments of the present invention will be described in detail with reference to FIGS. Since the scale is appropriately changed for easy understanding, the figure is not similar to the actual one.

  FIG. 1 is a diagram showing the shape and structure of a wheelchair weight scale according to the present invention. FIG. 1A is a view seen from above, FIG. 1B is a view seen from the right side of FIG. 1A, and FIG. 1C is a view seen from below in FIG. Since (a) and (b) in FIG. 1 are vertically symmetric, the lead-in lines and reference numerals in the lower part are omitted.

  A pair of vehicle mounts 1 for mounting the left and right wheels of a wheelchair are a pair of support 2 that hardly deforms and a bendable first connecting portion 12 that connects the supports to each other and a bend that connects the vehicle mount and the support. They are connected by connecting means comprising a possible second connecting portion 13. For example, a hinge or the like is used for the bendable first and second connecting portions 12 and 13. The dimension in the longitudinal direction of the in-vehicle table 1 is sufficiently longer than the distance between the front wheel and the rear wheel of the wheelchair, for example, 80 cm. The distance between the inner sides of the pair of vehicle mounts 1 is slightly narrower, for example, 26 cm than the distance between the left and right wheels of the small wheelchair, and the distance between the outer sides of the pair of vehicle mounts 1 is, for example, 80 cm, slightly wider than the distance between the left and right wheels of the large wheelchair. Therefore, the width of one vehicle-mounted base is about 27 cm. There are an outer frame 3 and an inner frame 4 on both sides of the width of each vehicle mount so that the wheels do not protrude. With such a structure, the wheelchair weight scale can be folded and the width can be reduced to about 1/3 of the conventional one.

  Since the weight of the wheelchair is applied to the pair of vehicle mounts 1 and no great force is applied to the pair of supports 2, the pair of supports 2 can be made of a light material less than 1/10 of the pair of vehicle mounts 1. Can reduce the weight of the whole wheelchair scale.

  On the left side of FIG. 1A, there is a slope 8 for entering a wheelchair. The slope 8 can be connected to the vehicle-mounted base 1 through a third connecting portion 14 that can be bent, such as a hinge, and can be folded. As shown in FIG. 1 (c), there is a slope base 15 at the bottom of the connecting portion 14 of the slope 8, when a wheelchair is put on the slope 8 and the wheel comes near or above the third connecting portion 14. In addition, since the base 15 is on the floor 16, the other end of the vehicle-mounted base 1 (the portion of the travel prevention frame 5) is not lifted. On the slope side of the in-vehicle stand 1, there is a shallow depression 11 into which the rear wheel of the wheelchair enters. The wheelchair brake is applied in a state where the rear wheel of the wheelchair enters the depression 11, and the weight is measured by stabilizing the wheelchair. The slope 8 is only on one side of the vehicle-mounted base 1 (the left side of FIGS. 1 (a) and 1 (c)), and the other end has a progress preventing frame 5 as a progress preventing mechanism so that the front wheel of the wheelchair does not advance any further. is there. After measuring the weight, turn the wheelchair back and go down the slope 8 backwards.

  A rear sensor 6 is provided in the lower part of the wheelchair where the rear wheel is located, and a front sensor 6 is provided in the lower part of the rear sensor 6 for measuring the weight. There is a sensor 7. One vehicle-mounted base has two rear sensors 6, two front sensors 7, and a total of eight sensors for both vehicle-mounted bases. The total weight measured by these sensors is the total weight. Since most of the weight of the wheelchair is applied to the position of the rear wheel, the rear reinforcing plate 9 is made of a material or structure having stronger strength than the front reinforcing plate 10.

  FIG. 2 is a view showing a method of folding the wheelchair weight scale of the present invention. FIG. 2A shows a state in which the weight is measured, that is, a view before folding, and corresponds to FIG. However, FIG. 2 shows latches 17a, 17b and fasteners 18a, 18b not shown in FIG. 1 to avoid complexity. The latch 17a is a plate having a hole, and the latch 17b is a round bar that moves in the longitudinal direction. The bent portion is fixed by the round bar of the latch 17b entering the hole of the latch 17a. The fasteners 18a and 18b are, for example, patchon locks that are also used for bags and the like, and are used to fix the opening / closing part. Further, the lead-in lines and the reference numerals of the left and right symmetrical portions in FIG. 2 are omitted.

  When the wheelchair weight scale of the present invention is folded, first, the central portion is lifted as shown in FIG. The connecting portions 12 and 13 can be bent, and the center is lifted as shown in the figure, and the support 2 and the vehicle-mounted base 1 are brought close to the center. As shown in FIG. 2C, the central portion is further lifted until the left and right support bodies 2 are closed, and a round bar of the latch 17b is inserted into the hole of the latch 17a so that the support body 2 is not opened.

  Next, as shown in FIG. 2D, both ends are lifted to open the Patchon lock 18a, and as shown in FIG. 2E, the Patchon lock 18a and the Patchon lock 18b are closed with the left and right vehicle-mounted bases 1 completely closed. To prevent the folded wheelchair scales from opening.

  FIG. 3 is a diagram showing a folded state of the wheelchair weight scale of the present invention. FIGS. 1 and 2 show handles 19 (a) and 19 (b) which are omitted for the sake of simplicity. ing. 3A is a view of the folded state of FIG. 2E viewed from the right side, and FIG. 3B shows a state where FIG. 3A is turned 90 degrees to the left. FIG. FIG. 3C is a view of FIG. 3A viewed from below, and FIG. 3D is a view of the state where FIG. 3C is rotated 90 degrees to the left. As can be seen from FIG. 3, the wheelchair weight scale of the present invention is folded to be very small and can be easily carried with the handle 19a or 19b. In addition, it can be seen that if it is stored in an upright state, a very small storage space is sufficient.

  FIG. 4 is an enlarged view of the slope 8, the rear reinforcing plate 9, and the recess 20 of the wheelchair weight scale of the present invention, and the concave portion 20 is formed in the upper portion of the rear reinforcing plate. When measuring the weight, put the wheelchair in the order of the front wheel and the rear wheel from the slope 8. At this time, the weight of the wheelchair applied to the slope is applied to the floor 16 through the slope table 15, and the end of the vehicle-mounted table 1 is not lowered and the other end is not lifted. As shown in FIG. 4 (a), the rear wheel 21 is placed at the position of the recess 20, the wheelchair brake is applied, and the weight is measured. There is a rear sensor 6 directly below, and most of the weight is applied to this position, so that the weight can be stably measured. The depression 20 is adapted to the maximum diameter of the rear wheels of various wheelchairs, and the depth of the depression 20 is about 5 to 10 mm.

  FIG. 5 shows another example of a concave recess. Rather than digging the flat plate of the in-vehicle table 1 to make a recess, the guard 22 is formed on both sides of the portion on the flat plate of the in-vehicle table 1 to form a substantially concave shape, and the rear wheel is the guard 22 It is intended to fit in the inside.
