Description

[Technical field]

[0001] The present invention relates to a weight scale, and more particularly to a weight scale having a slope. [Background technology]

[0002] For example, weight scales such as wheelchair weight scales and medical scales are provided with a slope so that the person to be weighed can step onto the weighing platform without having to raise their feet too high.

[0003] For example, in Patent Document 1, a guide path (slope) that can rotate and be folded onto the weighing platform is provided. If the slope comes into contact with the floor surface, a weighing error will occur, so the slope is normally biased upward by a spring so that it does not come into contact with the floor surface. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Utility Model Application Publication No. 2-140426 Summary of the Invention [Problem to be solved by the invention]

[0005] However, in the above-mentioned weighing scales, the ramp does not contact the floor, so a step is created between the ramp and the floor. People with walking disabilities who need the ramp may trip over this step, which is very dangerous.

[0006] The present invention has been made in consideration of the above problems, and provides a weighing scale that allows a person to be weighed to safely step onto the weighing platform. [Means for solving the problem]

[0007] In order to solve the above problems, in one aspect of the present disclosure, a weighing scale is configured to include a weighing platform on which the object to be weighed is placed, legs located at the four corners of the weighing platform and placed on a floor surface, a first slope provided on the side of the weighing platform and spaced apart from the floor surface, and a second slope placed on the floor surface and eliminating the difference in level between the floor surface and the first slope.

[0008] According to the above embodiment, the two slopes provide a continuous lead-in path from the floor to the weighing platform. The person to be weighed can ascend from the floor to the tread of the weighing platform by ascending the second slope, the first slope, and the weighing platform in that order. The second slope fills the height gap between the first slope and the floor, allowing the person to ascend to the weighing platform more safely.

[0009] According to one embodiment, the second slope engages with the leg and is spaced apart from the first slope and the weighbridge. According to this embodiment, the second slope engages with the leg and does not come off. Since the second slope is spaced apart from the weighbridge and the first slope, it does not adversely affect weighing.

[0010] According to one embodiment, an engaged member having a slit is fixed to the leg, and the second slope is provided with an engaging portion corresponding to the shape of the slit, and the second slope engages with the leg by inserting the engaging portion into the slit. According to this embodiment, the second slope can be fixed by inserting the engaging portion into the slit, and the second slope can be easily engaged.

[0011] In one embodiment, the weighing platform has a bottomless recess on the surface facing the second slope, and the engaged member is disposed at a position that forms the bottom of the recess and is spaced from the recess, with the slit being inside the recess when viewed from above. According to this embodiment, the engaged part protrudes and is exposed, making engagement easy, and the slit that forms the engaged part is disposed inside the recess, making it safe. Effect of the Invention

[0012] According to the above configuration, it is possible to provide a weighing scale that enables a person to safely step onto the weighing platform. [Brief description of the drawings]

[0014] Hereinafter, specific embodiments of the present invention will be described with reference to the drawings. The embodiments are illustrative and do not limit the invention, and all features and combinations described in the embodiments are not necessarily essential to the invention. In addition, in the following description of the embodiments and modifications, the same components are given the same reference numerals, and duplicated descriptions are omitted as appropriate.

[0015] (Weight scale 1) A weight scale 1 according to a preferred embodiment of the present disclosure will be described with reference to the drawings. Fig. 1 shows a perspective view of the weight scale 1 according to the embodiment. Fig. 2 shows a front view of the weight scale 1.

[0016] As shown in Figures 1 and 2, the weighing scale 1 is a large-sized weighing scale for medical use, such as a wheelchair weighing 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 corners below the weighing platform 20, and is used by placing the legs 8 on a floor surface FL.

[0017] The weighing platform 20 has a wide top surface that serves as the tread, is thin overall, and is placed close to the floor surface FL so that the person to be weighed can stand on it safely. Handrails 4 are provided on the left and right edges of the weighing platform 20 so that a person who has difficulty walking can hold on to it and stand up. A display unit 5 is provided on the weighing platform 20, and the load applied to the weighing platform 20 is displayed on the display unit 5 as the measurement result.

[0018] The weighing scale 1 is provided with two gentle slopes, a first slope 30 and a second slope 50, on the front and rear sides of the weighing platform 20, which become lower toward the outside, so that a person to be weighed in a wheelchair can get on to the weighing platform 20 while remaining in the wheelchair.

[0019] Fig. 3 is an enlarged front view (part A in Fig. 2) of the weighing scale 1. It mainly shows the attached state of the second slope 50. Fig. 3(A) shows the state where the second slope 50 has been removed. Fig. 3(B) shows the state where the second slope 50 has been attached. The first slope 30 is provided directly on the weighbridge 20, and the second slope 50 is configured as a separate body from the weighbridge 20 and is disposed outside the first slope 30 in a detachable manner.

[0020] The first slope 30 is provided integrally with the weighing platform 20 on the front and rear side surfaces of the weighing platform 20, and is disposed at a distance from the floor surface FL so as to prevent weighing errors. Therefore, as shown in Fig. 3(A), a step D1 is generated between the first slope 30 and the floor surface FL.

[0021] The second slope 50 is placed on the floor surface FL and is provided so as to eliminate the step D1 between the first slope 30 and the floor surface FL. As shown in Fig. 3(B) , by providing the second slope 50, the step 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 arranged in succession provide a gentle slope from the floor surface FL to the tread surface (horizontal surface) of the weighing platform 20, allowing the person to be weighed to step onto the weighing platform 20 without lifting their feet significantly.

[0022] The second slope 50 is disposed at a distance from the first slope 30 and the weighing platform 20 so as to prevent weighing errors. Furthermore, the second slope 50 engages with the legs 8, so that it will not fall off the weighing platform 20 due to an impact such as being kicked by the person being weighed. A non-slip surface is provided on the upper surface of the first slope 30, which is the inclined surface of the entry path, to prevent a wheelchair from slipping when it gets on top of it. A non-slip surface is also provided on the bottom surface of the second slope 50 to prevent the second slope 50 from slipping on the floor surface FL.

[0023] Fig. 4 is an exploded perspective view of the weighing scale 1. Note that the cover member 80 has a lower surface, which is omitted in Fig. 4. As shown in Fig. 4, the weighing scale 1 includes a weighing platform 20, a cover member 80 provided on the weighing platform 20, and a plurality of load sensors 40.

[0024] The weighing platform 20 is rectangular in plan view and is configured in a flat shape with a very low height compared to its size. The weighing platform 20 has base beams 21, 21 that form the left and right sides of the weighing platform 20, and a load plate 22 that is disposed 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 step onto the weighing platform 20 without lifting their feet significantly. Strain-generating bodies that are load sensors 40 are connected below the four corners of the weighing platform 20. The weighing platform 20 is supported only by the load sensors 40.

[0025] The cover member 80 is a member for hiding the base beam 21 and the internal mechanisms such as a computing device (not shown) attached to the base beam 21, and covers the base beam 21 and is attached to the base beam 21 to conceal the base beam 21 and the internal mechanisms from the outside. The handrail 4 and the display unit 5 are erected on the cover member 80, and the cover member 80 including the handrail 4 and the display unit 5 is supported by the load sensor 40 via the weighing platform 20. The cover member 80 is supported by the base beam 21 away from the floor surface FL and 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 standing on the weighing platform 20 grabs or leans on the handrail 4, the weighing value of the weighing scale 1 is not affected.

[0026] The load sensor 40 calculates the change from a predetermined standard state as the load. That is, when nothing is placed on the weighing platform 20, the load acting as a weight is applied to the weighing platform 20 and detected by the load sensor 40, and the difference value is converted into a weight and displayed on the display unit 5. If the person to be weighed is in a wheelchair, it is possible to store the weight of the wheelchair in advance and calculate the difference value to display the weight of the person to be weighed.

[0027] (Load sensor) 5 is a vertical end view of part A along line VV in FIG. 2. The load sensor 40 is 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 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 pair of eyeglass-shaped through holes is drilled on the side of the load sensor 40, and a strain gauge (not shown) is attached to the thin-walled part where the through hole is provided. The thin-walled part is deformed by fixing the fixed end 42 and applying a load to the movable end 41, and this deformation is converted into an electric signal by the strain gauge and then converted into a weight value. A screw hole (not shown) is provided on 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, sandwiching a flat intermediate member 46 therebetween.

[0028] 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 and fixed to the lower surface of the base beam 21, supporting 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. A storage space that is greatly recessed upward from the bottom surface is provided in the base beam 21, and the load sensor 40 is fixed to the upper surface of the storage space, thereby raising the fixing surface between the base beam 21 and the load sensor 40, and relatively lowering the position of the load plate 22 fixed to the base beam 21. The upper surface of the load plate 22 is the stepping surface of the person to be weighed, and the stepping surface is arranged closer to the floor surface FL to increase safety.

[0029] A fixed plate 48 is fastened to the bottom surface of the fixed end 42 of the load sensor 40 by a fixing member (not shown). A leg 8 that abuts against a floor surface FL is disposed on the bottom surface of the fixed plate 48. A screw 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 leg 8, the amount of protrusion of the leg 8 can be adjusted, and the weighing platform 20 can be adjusted to be horizontal.

[0030] An engaged member 60 is fixed to the fixed plate 48. The engaged member 60 is a member that engages with the second slope 50. The engaged member 60 is formed by bending a flat plate 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 fixed plate 48, and the lower horizontal surface 63 is disposed near the floor surface FL.

[0031] The cover member 80 has inwardly recessed cover recesses 81 on both front and rear end surfaces, and an opening 82 is formed in the lower region of the cover recess 81, which continues to the bottom surface of the cover member 80. The engaged member 60 fixed to the fixing plate 48 has at least a portion of its lower horizontal surface 63 exposed from the opening 82. A cut (slit 64) having an inverted L shape in plan view is formed on the lower horizontal surface 63. This slit 64 is an engaged portion that directly engages with the engaging portion 54.

[0032] 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, but it is contained within the cover recess 81 provided in the cover member 80, and the tip of the lower horizontal surface 63 does not protrude from the cover recess 81, thereby providing a high level of safety.

[0033] (Second slope) The shape of the second slope 50 and a method for attaching and detaching the second slope 50 will be described in detail. Fig. 6 is an enlarged perspective view of the weighing scale 1. Note that the cover member 80 is omitted in Fig. 6. Fig. 6(A) shows the state before the second slope 50 engages with the weighing platform 20. Fig. 6(B) shows the state after the second slope 50 engages with the weighing platform 20.

[0034] The second slope 50 is configured as a separate body from the weighbridge 20 and is detachable from the weighbridge 20. The second slope 50 has approximately the same width as the width (length in the left-right direction) of the weighbridge 20 and is disposed in front of (outside of) the first slope 30, eliminating the height gap (step D1) between the first slope 30 and the floor surface FL.

[0035] The second slope 50 has a cross-sectional outline in the longitudinal direction that is a right-angled triangle, and has three sides extending in the longitudinal direction: a bottom surface 51 that lands on the floor surface FL, an inclined surface 52 that serves as the tread surface, and a vertical surface 53 that faces the weighing platform 20.

[0036] 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 that faces the weighbridge 20. The engaging portion 54 is an L-shaped bent flat plate in a plan view, and has a shape that corresponds to the L-shaped slit 64 that is the engaged portion.

[0037] When engaging the second slope 50 with the weighbridge 20, the second slope 50 is lifted slightly, the engaging portion 54 is aligned with the lower horizontal surface 63 exposed from the weighbridge 20 placed on the floor surface FL, and the engaging portion 54 is inserted from above into the slit 64. When the L-shaped engaging portion 54 is inserted halfway into the L-shaped slit 64, the bottom surface 51 of the second slope 50 lands on the floor surface FL. This engages the second slope 50.

[0038] (Action and effect) The second slope 50 eliminates the gap between the first slope 30 provided on the weighing platform 20 and the floor surface FL. The first slope 30 and the second slope 50 allow the person to climb up safely from the floor surface FL to the weighing platform 20 without any steps, using both slopes as a route.

[0039] Conventionally, there have been separate slopes provided separately from the weighbridge, but because the weighbridge had to be accessed only by the separate slope, the slope was large at the height of the weighbridge and was difficult to carry and install. In this embodiment, the second slope 50 eliminates the step D1 between the first slope 30 and the floor surface FL, so a slope with a height of about the step D1 is sufficient, making it small and lightweight, and easy to carry and install.

[0040] Conventionally, a separate slope provided separately from the weighbridge has been fixed to the weighbridge by lifting it up and engaging it with the legs. However, the weighbridge is heavy, and lifting it up and attaching the separate slope to the legs is a difficult task for one person to perform. According to this embodiment, when attaching the second slope 50 to the weighbridge 20, it is not necessary to lift the heavy weighbridge 20, and it is only necessary to fit the second slope 50, which is lighter and smaller than the weighbridge 20, from above, and the second slope can be safely and easily engaged with the weighbridge 20.

[0041] When the engaging portion 54 engages with the slit 64 and the bottom surface 51 lands on the floor surface FL, the second slope 50 including the engaging portion 54 comes into contact with only a part of the exposed engaged member 60 and is disposed slightly spaced apart from the first slope 30 and the cover member 80, and does not come into contact with the weighing platform 20 or the parts attached thereto. Therefore, the second slope 50 does not come into contact with the weighing platform 20 and apply a load thereto, causing an error in the weighing value of the weighing scale 1.

[0042] FIG. 7 is a diagram showing the removal of the second slope 50. It corresponds to FIG. 6. See also FIG. 1. When moving the weighing scale 1, the second slope 50 needs to be removed and carried. The weighing scale 1 has a handle 3 on one side and wheels 7 on the other side (see FIG. 1). When moving the weighing scale 1, the handle 3 is grasped and the side with the wheels 7 is used as a fulcrum to lift the side with the handle 3 to tilt the weighing platform 20, and the wheels 7 are placed on the ground to move the weighing scale 1 with the wheels 7. When the handle 3 is grasped and the weighing platform 20 is lifted, the engagement part 54 passes through the slit 64 and the engagement is naturally released, and the second slope 50 remains on the floor surface FL. When the second slope 50 is removed, it is when the weighing scale 1 is moved, so when the weighing platform 20 is lifted to move it, 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 simply lift the second slope 50 and insert the engagement portion 54 into the slit 64 to remove it from the weighing platform 20.

[0043] Since the slit 64 is L-shaped in a plan view, when the second slope 50 engages with the slit 64, movement in both the left-right and front-back directions is suppressed. 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, and may be a T-shape, an inverted J-shape, a hook shape, or the like.

[0044] (Cover member 80) In this embodiment, the cover recess 81 of the cover member 80 has a shape suitable for mounting the second slope 50. This will be described in detail with reference to the drawings. Fig. 8 is an enlarged front perspective view of the weighing scale 1, with the second slope 50 removed. See also the enlarged front view of Fig. 3.

[0045] As described above, the cover member 80 has front and rear end faces each provided with a cover recess 81, and the lower horizontal surface 63 of the engaged member 60 is exposed from an opening 82 provided in a lower region of the cover recess 81.

[0046] The cover recess 81 has a shape recessed inward in two stages. As shown in Fig. 8, a first recess 83 recessed toward the rear is provided in a cover front surface 88 which is the front end surface of the cover member 80, and a second recess 85 recessed further toward the rear is provided in the recessed surface of the first recess 83 (first standing wall 84 which is the rear surface).

[0047] Moreover, the cover recess 81 is formed to be recessed rearward, penetrating to the lower end of the cover front surface 88 and the bottom surface of the cover member 80. That is, the cover recess 81 has no bottom, and the constituent surfaces of the first recess and the second recess 85 have no lower surface, and the lower horizontal surface 63 of the engaged member 60 protruding from the opening 82 is disposed at a position that becomes the bottom surface of the cover recess 81, spaced apart from the cover member 80.

[0048] The ceiling surfaces of the first recess 83 and the second recess 85 are 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.

[0049] The cover member 80 configured as described above assists the engagement of the engagement portion 54 with the slit 64. Figure 9 is a partial horizontal cross-sectional view for explaining the engagement of the engagement portion 54 with 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 indicated by a two-dot chain line. Figures 9(A) and 9(B) show the engagement process.

[0050] 9(A), in order to engage the second slope 50 with the weighbridge 20, first, the second slope 50 is lifted and the vertical surface 53 is placed facing the weighbridge 20, and the engagement portion 54 protruding from the vertical surface 53 is inserted into the cover recess 81. In detail, when the base end surface of the engagement portion 54, which is L-shaped in plan view, that is fixed to the vertical surface 53 is defined as the first surface 54a, and the tip surface that is bent and continues from the base end surface is defined as the second surface 54b, the engagement portion 54 is inserted into the cover recess 81 so that the second surface 54b abuts against the second standing wall 86 of the cover recess 81.

[0051] At this time, since the ceiling surface 87 of the cover recess 81 is gently inclined toward the second standing wall 86, when the engaging portion 54 abuts against the ceiling surface 87, it is guided toward the second standing wall 86. In addition, when the vertical surface 53 of the second slope 50, which is the surface facing the weighbridge 20, is brought into contact with the cover front surface 88 of the cover member 80, the second surface 54b is also set to abut against the second standing wall 86. In this manner, the configuration is such that the operator can know the insertion amount of the engaging portion 54 without looking into the cover recess 81.

[0052] In addition, slope covers 55 are provided on both ends of the second slope 50 to cover the ends. The slope covers 55 are larger than the second recesses 85 and do not enter the second recesses 85 but only enter the first recesses 83. Only the engagement parts 54 protruding from the slope covers 55 enter the second recesses 85.

[0053] With the above-described configuration, the second surface 54b of the engagement portion 54 can be guided to the second standing wall 86 located at the innermost position of the cover recess 81. Both the second standing wall 86 and the second surface 54b are vertical planes, and the planes come into stably contact with each other.

[0054] As described above, the lower horizontal surface 63 in which the L-shaped slit 64 serving as the engaged portion is formed is disposed in the lower region of the cover recess 81. As shown in Figures 9(A) and 9(B), if the straight cutout on the entrance side of the L-shaped slit 64 is the first slit 64a and the straight portion on the far side perpendicular to the first slit 64a is the second slit 64b, the engaged member 60 is configured such that the second slit 64b is in front of (outside of) the second recess 85 in plan view.

[0055] When the second slope 50 is moved downward to touch the floor surface FL while the second surface 54b is in contact with the second standing 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 in this state, the engaging portion 54 is inserted into the slit 64, and the second slope 50 lands on the floor surface FL due to its own weight. The engaging portion 54 engages with the slit 64, and the second slope 50 lands on the floor surface FL with the second slope 50 inserted into the slit 64 partway in the vertical direction, and the horizontal movement of the second slope 50 is restricted.

[0056] In plan view, the second slit 64b is provided not vertically below the second standing wall 86, but slightly toward the opening side of the cover recess 81, at a distance D2. This is because if the second slope 50 abuts against the cover member 80, the second slope 50 will be in contact with the weighing platform 20 and apply a load thereto, causing an error in the weighing of the weighing scale 1, and therefore it is necessary to separate the two. 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 standing wall 86, and the second slope 50 engaged with the engaged member 60 is configured to be positioned at a distance D2 from the weighing platform 20.

[0057] The cover front surface 88 is the surface facing the second slope 50 of the weighbridge 20, and a bottomless cover recess 81 is provided on the cover front surface 88, and a slit 64 that serves as the engaged part, spaced apart from the cover member 80, is disposed at the bottom of the cover recess 81. The engaged part does not protrude from the cover member 80, so it 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 from above through the slit 64 located on the bottom surface.

[0058] In this embodiment, the load sensors 40 are arranged at the four corners of the weighing platform 20 using strain-generating bodies, but this is not limited to this and any conventionally known load sensors or other weighing mechanisms may be used, and the arrangement and number of the load sensors are also not limited to the above. Furthermore, 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 arranged within the recess and away from the cover member 80.

[0059] The above describes preferred embodiments and modified examples of the present invention. However, the above-described embodiments are merely 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 included in the scope of the present invention.
