Description

TECHNICAL FIELD The present invention relates to a weight scale, and particularly to a weight scale equipped with a slope.

For example, weighing scales such as wheelchair scales and medical scales are provided with a slope so that a person to be weighed can climb onto the weighing stand without having to raise their feet.

For example, in Patent Document 1, an introduction path (slope) that can be rotated and folded into a weighing platform is provided. If the slope comes into contact with the floor, a measurement error will occur, so the slope is normally biased upward by a spring to such an extent that it does not come into contact with the floor.

Utility Model Publication No. 2-140426

However, in the scale described above, the slope does not come into contact with the floor surface, so a difference in level occurs between the slope and the floor surface. People with walking disabilities who require a slope may trip over these steps, which is extremely dangerous.

The present invention has been made in view of the above problems, and provides a weighing scale that allows a person to be weighed to safely climb onto a weighing platform.

In order to solve the above problem, an aspect of the present disclosure includes a weighing platform on which an object to be weighed is placed, legs arranged at four corners of the weighing platform and landing on the floor, and a side surface of the weighing platform. a first slope provided on the floor surface and arranged apart from the floor surface; and a second slope arranged so as to land on the floor surface to eliminate a step difference between the floor surface and the first slope. The scale was configured so as to be prepared.

According to the above aspect, the two slopes provide a continuous introduction path from the floor surface to the weighing platform. The person to be measured can ascend from the floor to the second slope, first slope, and weighing platform in this order, and then to the tread of the weighing platform. The second slope fills the height gap between the first slope and the floor surface, allowing the person to be weighed to climb up to the weighing stand more safely.

Moreover, according to a certain aspect, the second slope engages with the leg and is spaced apart from the first slope and the weighing platform. According to this aspect, since the second slope engages with the leg, it does not come off. Since the second slope is arranged apart from the weighing platform and the first slope, it does not adversely affect weighing.

Further, according to one aspect, an engaged member provided with a slit is fixed to the leg, and the second slope is provided with an engaging portion corresponding to the shape of the slit, The second slope is configured to engage with the leg by inserting the engaging portion into the slit. According to this aspect, the second slope can be fixed by inserting the engaging portion into the slit, and the second slope can be easily engaged.

Further, in one aspect, the weighing platform is provided with a bottomless recess on the opposing surface facing the second slope, and the engaged member is located at the bottom of the recess. The slit is arranged at a distance from the recess, and the slit is located inside the recess when viewed from above. According to this aspect, the engaged portion protrudes and is exposed, making engagement easy, and the slit serving as the engaged portion is disposed within the recess, so it is safe.

According to the above configuration, it is possible to provide a weight scale that allows a person to be weighed to safely climb onto the weighing stand.

Hereinafter, specific embodiments of the present invention will be described with reference to the drawings. The embodiments are illustrative rather than limiting the invention, and all features and combinations thereof described in the embodiments are not necessarily essential to the invention. In addition, in the following description of the embodiment and modified examples, the same configurations are denoted by the same reference numerals, and overlapping description will be omitted as appropriate.

(Weight scale 1)
A weight scale 1 that is a preferred embodiment according to the configuration of the present disclosure will be described according to the drawings. FIG. 1 shows a perspective view of a weight scale 1 according to an embodiment. FIG. 2 shows a front view of the weight scale 1.

As shown in FIGS. 1 and 2, a scale 1 is a large medical scale such as a wheelchair scale. It has a weighing platform 20 on which a load to be weighed (a person to be weighed) is placed, and legs 8 arranged at the four lower corners of the weighing platform 20, and is used by landing the legs 8 on the floor surface FL.

In order for the person to be weighed to get on the weighing platform safely, the weighing platform 20 has a wide upper surface serving as a tread surface, is thin as a whole, and is disposed near the floor surface FL. Handrails 4 are erected on the left and right side edges of the weighing platform 20 so that a person to be weighed who is disabled or has difficulty walking can hold onto the weighing platform and stand. A display section 5 is provided upright on the weighing platform 20, and the load applied to the weighing platform 20 is displayed on the display section 5 as a measurement result.

The scale 1 has grooves on the front and back sides of the weighing platform 20 that become lower toward the outside so that even a person to be weighed in a wheelchair can get onto the weighing platform 20 while in a wheelchair. Two gentle slopes, a first slope 30 and a second slope 50, are provided.

FIG. 3 is an enlarged front view of the weight scale 1 (section A in FIG. 2). The attached state of the second slope 50 is mainly shown. FIG. 3(A) shows a state in which the second slope 50 is removed. FIG. 3(B) shows a state in which the second slope 50 is attached.
The first slope 30 is provided directly on the weighing platform 20, and the second slope 50 is configured separately from the weighing platform 20 and is detachably arranged outside the first slope 30.

The first slope 30 is provided integrally with the weighing platform 20 on the front and rear sides of the weighing platform 20, and is spaced apart from the floor surface FL so as not to cause measurement errors. Therefore, as shown in FIG. 3(A), a step D1 is created between the first slope 30 and the floor surface FL.

The second slope 50 is placed on the floor FL and is provided so as to eliminate the level difference D1 between the first slope 30 and the floor FL. As shown in FIG. 3(B), by providing the second slope 50, the level difference D1 from the floor surface FL to the first slope 30 is eliminated, and a gentle slope continues from the floor surface FL to the weighing platform 20. . The first slope 30 and the second slope 50 that are arranged continuously create a gentle slope from the floor FL to the tread (horizontal surface) of the weighing platform 20, so that the person being weighed can weigh without having to raise his or her feet significantly. You can go up to platform 20.

The second slope 50 is spaced apart from the first slope 30 and the weighing platform 20 so as not to cause measurement errors. Further, the second slope 50 is engaged with the leg 8, so that it will not fall off the weighing platform 20 due to an impact such as being kicked by a person being weighed. A non-slip device is provided on the upper surface of the first slope 30, which is the inclined surface of the approach path, to prevent the wheelchair from slipping. Further, a non-slip member is also provided on the bottom surface of the second slope 50 so that the second slope 50 does not slide on the floor surface FL.

FIG. 4 is an exploded perspective view of the weight scale 1. Note that the cover member 80 has a lower surface, but this is omitted in FIG. 4. As shown in FIG. 4, the weight scale 1 includes a weighing platform 20, a cover member 80 provided on the weighing platform 20, and a plurality of load sensors 40.

The weighing platform 20 has a rectangular shape in plan view, and is configured in a flat shape with a very low height relative to its size. The weighing platform 20 includes base beams 21, 21 forming left and right sides of the weighing platform 20, and a load plate 22 arranged and fixed between the base beams 21, 21. The first slope 30 is configured as a part of the load plate 22. The load plate 22 is fixed below the base beam 21 so that the person to be weighed can climb onto the weighing platform 20 without raising his/her feet significantly. A strain body, which is a load sensor 40, is connected below the four corners of the weighing platform 20. The weighbridge 20 is supported only by the load sensor 40.

The cover member 80 is a member that hides the base beam 21 and an internal mechanism such as an arithmetic device (not shown) attached to the base beam 21. The cover member 80 covers the base beam 21 and is attached to the base beam 21, so that the base beam 21 and Hide internal mechanisms from the outside. A handrail 4 and a display section 5 are erected on the cover member 80 , and the cover member 80 including the handrail 4 and the display section 5 is supported by the load sensor 40 via the weighing platform 20 . The cover member 80 is spaced apart from the floor FL and is supported by the base beam 21 in contact only with the weighing platform 20, and does not interfere with the load sensor 40. Therefore, even if the person to be weighed on the weighing platform 20 grabs or leans against the handrail 4, the measured value of the scale 1 is not affected.

In the load sensor 40, a change value from a predetermined standard state is calculated as a load. That is, the load that is applied to the weighing platform 20 and acting as weight from a state in which nothing is placed on the weighing platform 20 is detected by the load sensor 40, and the difference value is converted into weight and displayed on the display section 5. Is displayed. If the person to be weighed is in a wheelchair, by storing the weight of the wheelchair in advance, it is possible to calculate the difference value and display the weight of the person to be weighed.

(load sensor)
FIG. 5 is a vertical end view of section A taken along line VV in FIG. The strain body that is the load sensor 40 has a substantially rectangular parallelepiped shape that is long in one direction, and is arranged below the base beam 21 with its longitudinal direction aligned with the base beam 21 . One end of the strain body that is the load sensor 40 is a movable end 41 and the other end is a fixed end 42, and the fixed end 42 side is arranged toward the end of the base beam 21. A spectacle-shaped through hole is bored on the side of the load sensor 40, and a strain gauge (not shown) is attached to the thin wall portion provided with the through hole. By fixing the fixed end 42 and applying a load to the movable end 41, the thin wall portion is deformed, and this deformation is converted into an electrical signal by the strain gauge, which is then converted into a weight value. A screw hole (not shown) is provided in the upper surface of the movable end 41, and the movable end 41 is fastened to the bottom surface of the base beam 21 with a bolt across the flat intermediate member 46.

The base beam 21 is formed by fixing a plurality of metal flat plates or hollow members by welding or fastening. A storage space is provided below the base beam 21 to accommodate the load sensor 40. The load sensor 40 is accommodated in the storage space, fixed to the lower surface of the base beam 21, and supports the base beam 21 from below. An intermediate member 46 is interposed between the load sensor 40 and the base beam 21, so that the load sensor 40 does not come into contact with the base beam 21. By providing a storage space that is largely recessed upward from the bottom of the base beam 21 and fixing the load sensor 40 to the top surface of the storage space, the fixing surface between the base beam 21 and the load sensor 40 is raised, and the base beam is relatively recessed. The arrangement position of the load plate 22 fixed to the beam 21 is lowered. The upper surface of the load plate 22 is the tread surface of the person to be weighed, and the tread surface is arranged closer to the floor surface FL to improve safety.

A fixing plate 48 is fastened to the bottom surface of the fixed end 42 of the load sensor 40 by a fixing member (not shown). Legs 8 that come into contact with the floor surface FL are arranged on the bottom surface of the fixed plate 48. A threaded portion is provided at the tip of the leg 8, and by rotating the leg 8, the amount of protrusion from the fixed plate 48 changes. By rotating the legs 8, the amount of protrusion of the legs 8 can be adjusted, so that the weighing platform 20 can be adjusted to be horizontal.

An engaged member 60 is fixed to the fixed plate 48 . The engaged member 60 is a member that engages the second slope 50. The engaged member 60 is a flat plate bent into a crank shape, and has an upper horizontal surface 61, a vertical surface 62, and a lower horizontal surface 63. The upper horizontal surface 61 is fastened and fixed to the fixing plate 48, and the lower horizontal surface 63 is arranged near the floor surface FL.

A cover recess 81 that is recessed inward is provided on both front and rear end surfaces of the cover member 80 , and an opening 82 that continues to the bottom surface of the cover member 80 is formed in a lower region of the cover recess 81 . At least a portion of the lower horizontal surface 63 of the engaged member 60 fixed to the fixed plate 48 is exposed through the opening 82 .
An inverted L-shaped cut (slit 64) is formed in the lower horizontal surface 63 when viewed from above. This slit 64 is an engaged part that directly engages with the engaging part 54.

A portion of the lower horizontal surface 63 of the engaged member 60 protrudes and is exposed outside the cover member 80 in order to engage with the second slope 50; Since the tip of the lower horizontal surface 63 does not protrude from the cover recess 81, safety is high.

(Second slope)
The shape of the second slope 50 and the method for attaching and detaching the second slope 50 will be described in detail. FIG. 6 is an enlarged perspective view of the weight scale 1. Note that in FIG. 6, the cover member 80 is omitted. FIG. 6(A) shows a state before the second slope 50 engages with the weighing platform 20. FIG. 6(B) shows the state after the second slope 50 has engaged with the weighing platform 20.

The second slope 50 is configured separately from the weighing platform 20 and is removable from the weighing platform 20. The second slope 50 has approximately the same width as the width (length in the left-right direction) of the weighing platform 20, is arranged in front (outside) of the first slope 30, and has a height between the first slope 30 and the floor surface FL. Eliminate the gap (step D1).

The second slope 50 has a right triangular cross-sectional shape in the longitudinal direction, and has three surfaces extending in the longitudinal direction: a bottom surface 51 that lands on the floor FL, an inclined surface 52 that becomes a tread surface, and a surface facing the weighbridge 20. It has a vertical surface 53 serving as a plane.

A pair of engaging portions 54 that engage with the engaged member 60 are protruded from the left and right edges of the vertical surface 53 facing the weighing platform 20 . The engaging portion 54 is an L-shaped bent flat plate when viewed from above, and has a shape corresponding to the L-shaped slit 64 that is the engaged portion.

When engaging the second slope 50 with the weighing platform 20, lift the second slope 50 slightly, align the engaging portion 54 with the lower horizontal surface 63 exposed from the weighing platform 20 placed on the floor FL, and The joint portion 54 is inserted into the slit 64 from above. When the L-shaped engaging portion 54 is inserted into the L-shaped slit 64 to the middle, the bottom surface 51 of the second slope 50 lands on the floor surface FL. As a result, the second slope 50 is engaged.

(effect)
The second slope 50 eliminates the gap between the first slope 30 provided on the weighing platform 20 and the floor FL. The first slope 30 and the second slope 50 allow the person to be weighed to safely ascend from the floor FL to the weighing platform 20 without any steps, using both slopes as a route.

Previously, there was a separate slope that was installed separately from the weighbridge, but since the ramp had to be climbed to the weighbridge using only the separate ramp, the slope was at the same height as the weighbridge, making it large and difficult to carry and install. In this embodiment, since the second slope 50 eliminates the step D1 between the first slope 30 and the floor surface FL, the second slope 50 only needs to be a slope with a height of about the step D1, so it is small and lightweight, and easy to carry and install. It is.

Conventionally, a separate slope provided separately from the weighing platform was fixed to the weighing platform by lifting the weighing platform and engaging the legs. However, the weighing platform was heavy, and it was difficult for one person to lift it and attach the separate slope to the legs. According to this embodiment, when attaching the second slope 50 to the weighing platform 20, there is no need to lift the heavy weighing platform 20, and it is only necessary to fit the second slope 50, which is lighter and smaller than the weighing platform 20, from above. The second slope can be engaged with the weighing platform 20 safely and easily.

When the engaging portion 54 engages with the slit 64 and the bottom surface 51 lands on the floor FL, the second slope 50 including the engaging portion 54 contacts only a portion of the engaged member 60 that is exposed. The first slope 30 and the cover member 80 are arranged slightly apart and do not come into contact with the weighing platform 20 and the parts attached thereto. Therefore, the second slope 50 does not come into contact with the weighing platform 20 and apply a load, thereby preventing an error from occurring in the measured value of the weighing scale 1.

FIG. 7 is a diagram showing removal of the second slope 50. Corresponds to FIG. See also Figure 1. When moving the scale 1, the second slope 50 needs to be removed and carried. The weight scale 1 is provided with a handle 3 on one side and a wheel 7 on the other side (see FIG. 1). When moving the scale 1, hold the handle 3, use the side with the wheels 7 as a fulcrum, lift the side with the handle 3, tilt the weighing platform 20, let the wheels 7 touch the ground, and use the wheels 7 as a fulcrum. Move scale 1. When the weighing platform 20 is lifted by gripping the handle 3, the engaging portion 54 passes through the slit 64 and is naturally disengaged, leaving the second slope 50 on the floor FL. The second slope 50 is removed when the scale 1 is moved, so when the scale 20 is lifted for movement, the second slope 50 is naturally removed. There is no need to lift the weighing platform 20 to remove the second slope 50. Of course, it is also possible to lift the second slope 50 as it is, insert the engaging portion 54 into the slit 64, and remove it from the weighing platform 20.

Since the slit 64 is L-shaped in plan view, when the second slope 50 engages with the slit 64, movement is suppressed in both the left-right direction and the front-back direction. Therefore, the second slope 50 will not come off after engagement. The shape of the slit 64 is not limited to an inverted L shape, but may be a T shape, an inverted J shape, a hook shape, or the like.

(Cover member 80)
In this embodiment, the cover recess 81 of the cover member 80 has a shape suitable for attaching the second slope 50. This will be explained in detail using figures. FIG. 8 is an enlarged front perspective view of the weight scale 1. The second slope 50 is in a removed state. See also the enlarged front view of FIG.

As described above, the cover recess 81 is provided in the front and rear end surfaces of the cover member 80, and the lower horizontal surface 63 of the engaged member 60 is exposed through the opening 82 provided in the lower region of the cover recess 81. ing.

The cover recess 81 has a shape that is recessed inward in two stages. As shown in FIG. 8, a first recess 83 that is recessed toward the rear is provided in a cover front surface 88 that is the front end surface of the cover member 80. The vertical wall 84) is provided with a second recess 85 that is further recessed toward the rear.

Further, the cover recess 81 is formed to penetrate to the lower end of the cover front surface 88 and to the bottom surface of the cover member 80 and to be recessed rearward. That is, the cover recess 81 is bottomless, the first recess 85 and the second recess 85 have no lower surface, and the engaged member 60 protruding from the opening 82 is located at the bottom of the cover recess 81. A lower horizontal surface 63 of is spaced apart from the cover member 80 .

The ceiling surfaces of the first recess 83 and the second recess 85 form a common ceiling surface 87. Due to the ceiling surface 87, the ceiling surface of the cover recess 81 is a continuous inclined surface from the cover front surface 88 to the second standing wall 86 which is the rear surface of the second recess 85.

The cover member 80 configured as described above assists the engaging portion 54 to engage with the slit 64. FIG. 9 is a partial horizontal sectional view for explaining the engagement between the engaging portion 54 and the slit 64 and the shape of the cover member 80. The cover member 80 is shown in cross section, and the lower horizontal surface 63 is shown in dash-dotted lines. FIG. 9(A) and FIG. 9(B) show the engagement process.

In order to engage the second slope 50 with the weighing platform 20, first, as shown in FIG. The engaging portion 54 protruding from the cover 53 is inserted into the cover recess 81. Specifically, in the L-shaped engaging portion 54 when viewed from above, the proximal surface fixed to the vertical surface 53 is the first surface 54a, and the distal end surface that is bent and continuous from the proximal surface is the second surface 54b. , insert the engagement portion 54 into the cover recess 81 so that the second surface 54b contacts the second vertical wall 86 of the cover recess 81.

At this time, since the ceiling surface 87 of the cover recess 81 is gently inclined toward the second vertical wall 86, when the engaging portion 54 comes into contact with the ceiling surface 87, it is guided toward the second vertical wall 86. Further, when the vertical surface 53 of the second slope 50, which is the surface facing the weighing platform 20, is brought into contact with the cover front surface 88 of the cover member 80, the second surface 54b is also set to come into contact with the second vertical wall 86. ing. In this way, the structure is such that the operator can determine the insertion amount of the engaging portion 54 without looking into the cover recess 81.

Furthermore, slope covers 55 are provided at both ends of the second slope 50 to cover the ends. The slope cover 55 is larger than the second recess 85 and does not fit into the second recess 85, but only into the first recess 83, and only the engaging portion 54 protruding from the slope cover 55 fits into the second recess 85.

With the above configuration, the second surface 54b of the engaging portion 54 can be guided to the second vertical wall 86 located at the deepest position of the cover recess 81. Both the second standing wall 86 and the second surface 54b are vertical planes, and the planes stably abut each other.

As described above, the lower horizontal surface 63 in which the L-shaped slit 64 serving as the engaged portion is formed is arranged in the lower region of the cover recess 81 . As shown in FIGS. 9(A) and 9(B), in the L-shaped slit 64, the straight notch on the entrance side is the first slit 64a, and the straight line on the back side that is perpendicular to the first slit 64a. When the portion is defined as a second slit 64b, the engaged member 60 is configured such that the second slit 64b is located in front (outside) of the second recess 85 in plan view.

When the second slope 50 is moved downward to be grounded to the floor FL while the second surface 54b is in contact with the second vertical wall 86, it comes into contact with the lower horizontal surface 63 disposed below the cover recess 81. . When the second slope 50 is pulled slightly forward, the engaging portion 54 is inserted into the slit 64, and the second slope 50 lands on the floor FL due to its own weight. The engaging portion 54 engages with the slit 64, and the second slope 50 lands on the floor FL while being inserted into the slit 64 halfway in the vertical direction, and the movement of the second slope 50 in the horizontal direction is restricted. Ru.

In plan view, the second slit 64b is not provided vertically below the second standing wall 86, but is provided slightly toward the opening of the cover recess 81 by a distance D2. This is because if the second slope 50 is in contact with the cover member 80, the second slope 50 will be in contact with the weighing platform 20 and applying a load, which will cause an error in the weighing of the scale 1. This is because it is necessary to space them apart. Since the cover member 80 is included in the weighing platform 20, the slit 64 is provided horizontally at a distance D2 from the second vertical wall 86, so that the second slope 50 engaged with the engaged member 60 is distanced D2 from the weighing platform 20. They are arranged so that they are spaced apart.

The cover front surface 88 is a surface facing the second slope 50 of the weighing platform 20 , and a bottomless cover recess 81 is provided in the cover front surface 88 . A slit 64 serving as an engaging portion is arranged. The engaged portion does not protrude from the cover member 80 and is safe. Furthermore, engagement can be easily achieved by simply inserting the engaging part 54 into the cover recess 81 and passing the engaging part 54 through the slit 64 located on the bottom surface from above.

In this embodiment, the load sensors 40 are arranged at the four corners of the weighing platform 20 using strain-generating bodies, but the present invention is not limited to this, and conventionally known load sensors or other weighing mechanisms may be used. The arrangement and number of load sensors are also not limited to the above. Further, the form of the cover recess 81 is not limited to a two-stage recess, but may be formed as a simple recess, and the engaged member 60 may be disposed within the recess and spaced apart from the cover member 80. .

Although preferred embodiments and modified examples of the present invention have been described above, the above-mentioned embodiments are only examples of the present invention, and these can be combined based on the knowledge of those skilled in the art, and such forms are also covered by the present invention. within the scope of the invention.
