Description

TECHNICAL FIELD The present invention relates to an underfloor inspection port structure with a scale for use in general homes and various facilities by embedding the scale in the floor.

Periodic measurement of body weight is an important habit for health management in general households, nursing homes, and the like. In recent years, scales have become thinner and no longer as bulky as they used to be, but if you leave them on the floor, they can still get in the way and cause you to trip over them. Therefore, it is common to keep it in a cupboard or the like and take it out only when you need to use it and place it on the floor. However, when using the device in a changing room after taking a bath, for example, it was troublesome to put it in and take it out, so I sometimes forgot to measure it. Also, in a small changing room, it may be difficult to even find a place to put the scale.

If you can install the scale embedded in the floor, you won't have to worry about putting it in and taking it out, and you won't have to worry about where to put it. The floor-embedded structure of the weight scale described in Patent Document 1 was proposed in order to eliminate such troublesomeness of cleaning up the weight scale. In the floor-embedded structure of the weight scale described in Patent Document 1, a receiver having a "H"-shaped cross section is installed at the periphery of an opening provided in the floorboard, and the weight scale is installed in the receiver. A liquid receiving gutter material in the form of a groove that opens upward is installed around the weight scale, and a surface cover panel having a peripheral wall part hanging downward on the periphery is installed to cover the weight scale from above.

The front cover panel can be removed while leaving the scale in place, so maintenance of the scale is easy. Furthermore, since there is a liquid-receiving gutter material, there is an advantage that the scale will not get wet even if water is spilled on the floor or drops of water fall from a wet body in a changing room or the like.

However, according to the structure described in Patent Document 1, the front cover panel, which is larger than the scale, is placed on top of the scale, so when stepping on the edge of the front cover panel, there is a risk that the opposite side will jump up. was there. Furthermore, when measuring weight, the front cover panel must move up and down, so if the up and down movement is obstructed by foreign objects, the measured value may be affected. Furthermore, since the front cover panel is structurally heavy, if it is applied to the scale, the upper limit of the measurable load will be reduced. Additionally, if the front cover panel is made of metal, there are problems such as the top plate feeling cold in winter.

The floor-embedded structure of the scale described in Patent Document 2 was designed to prevent the surface cover panel (footrest board) from jumping up, which was a drawback of the structure described in Patent Document 1. The back of the footrest has a complex structure with a fixed rail and a movable rail to prevent it from jumping up, which is costly, and there is a knob on the surface that moves the operating rail, which makes it difficult to design and use. There's a problem.

The problem to be solved by the present invention is to propose an underfloor inspection port structure with a weight scale that can be easily and inexpensively installed on the floor.

In order to solve the problem, one aspect of the present invention is that the inner frame of the underfloor inspection opening is supported by the outer frame of the underfloor inspection opening, and the inner frame of the underfloor inspection opening has a space in the center in which a weight scale can be installed. In the underfloor inspection port structure with a scale, the outer peripheral part of the partition plate is supported, and a scale installed in the center part of the partition plate is fixed to the partition plate.

Since the underfloor inspection port structure with a weight scale according to the present invention uses the outer frame and inner frame of a commercially available underfloor inspection port, it can be realized at a relatively low cost and can also function as an underfloor inspection port.
The underfloor inspection port structure with a scale according to the present invention has a simple configuration in which a commercially available underfloor inspection port is used and a partition plate on which the scale is placed and a scale are added, so it is relatively easy to use. Moreover, it can be realized at low cost.
Furthermore, by fixing the scale to the partition plate, even if the weight is applied to the edge of the scale, the scale can be prevented from falling over.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An underfloor inspection port structure with a weight scale according to the present invention will be described in detail below with reference to the drawings. FIG. 1 is an explanatory cross-sectional view showing one embodiment of an underfloor inspection port structure with a weight scale according to the present invention.

In the underfloor inspection port structure with a scale of this example, a partition plate having a space in the center in which a scale 1 can be installed is provided inside the inner frame 4 of the underfloor inspection port having an outer frame 5 and an inner frame 4. 3 is installed, and the scale 1 is installed so that the height of the top plate of the scale 1 is 1 mm or more higher than the height of the outer periphery of the partition plate 3. The decorative sheet 2 that covers the surface of the scale 1 is not attached to the outer periphery of the partition plate 3, but is installed only on the surface of the scale 1, so that the decorative sheet 2 and the outer periphery of the partition plate are in contact with each other. The width of the unfilled part is 30 mm or more.

The height of the top plate of the scale 1 is set to be 1 mm or more higher than the height of the surface of the partition plate 3, and the decorative sheet 2 is not adhered to the surface of the partition plate 3, but is attached to the surface of the scale 1. By installing the decorative sheet by adhering it only to the surface and providing sufficient rigidity to the decorative sheet, the width where the decorative sheet around the scale and the surface of the partition plate are not in contact is set to 30 mm or more. When the scale moves downward during weight measurement, the decorative sheet 2 on the partition plate 3 moves laterally, but there is no problem with the adverse effect on the measured value due to the decorative sheet 2 coming into contact with the partition plate 3. can be kept at the level. In addition, even if there is a foreign object such as dust between the decorative sheet and the inner frame, the decorative sheet on the partition plate will not move in the vertical direction, so the effect will be small and it will not affect the measured value in practical use. There will be no negative effects.

FIG. 6 is an enlarged sectional view showing the relationship between the partition plate and the decorative sheet. Since the decorative sheet has rigidity, the width 14 of the gap where the decorative sheet 2 is not in contact with the partition plate 3 is 30 mm or more due to the difference in level between the weight scale 1 and the partition plate 3.

To explain in more detail the floor-embedded structure of the weighing scale according to the present invention shown in FIG. 1, a flooring material 6 is generally constructed on the surface of a base material 7. The floor material 6 is a decorative material, and the base material 7 ensures the rigidity of the floor. The base material 7 is supported by joists, and reinforcing joists 8 are generally installed around the inspection opening. A support square member 9 is attached to the reinforcing joist 8 to support the underfloor inspection door outer frame 5.

The partition plate 3 has an outer size that fits within the inner frame 4 of the underfloor inspection port, and has a space in the center where the weight scale 1 can be installed. At this time, the depth of the space is designed so that the height of the top plate of the weight scale 1 is 1 mm or more higher than the height of the outer peripheral part of the partition plate 3.

The material of the partition plate 3 may be a laminated structure of wood materials such as water-resistant plywood or particle board, or a press-molded metal plate. Furthermore, a metal or plastic reinforcing material may be combined with the wooden material. Since there is a lot of humidity under the floor, the material of the partition plate 3 needs to be resistant to moisture and difficult to deform due to moisture. It also needs to have sufficient strength and durability as a partition plate for an underfloor inspection port.

In the example of FIG. 1, a battery exchange hole 12 is provided in the center of the partition plate 3. This is to replace the battery of the scale 1. A square lumber may be attached or a storage box may be stored under the partition plate in order to safely catch the partition plate in case it falls. Alternatively, the opening may be covered with a heat insulating material.

In the example shown in FIG. 2, a cutting portion (trimming) with a depth of 0.5 mm or more and 2 mm or less is provided on a portion of the outer peripheral edge of the surface of the partition plate 3, and the upper surface of the partition plate 3 and A gap (Tr) is provided between the underfloor inspection port inner frame 4 and the underfloor inspection port inner frame 4. By doing so, even if the decorative sheet 2 and the inner frame 4 are in contact with each other, the decorative sheet 2 is not pinched between the inner frame 4 and the partition plate 3, and more accurate weight measurement is possible.

FIG. 3 is an explanatory plan view showing an example of the decorative sheet 2. As shown in FIG. In this example, a window 17 through which the display of the scale 1 can be viewed and an electrode plate opening 18 for measuring the body fat percentage of the scale 1 are provided. The window 17 may have a structure consisting of only a transparent rigid resin sheet and no decorative sheet applied to this portion, or may simply have a hole. Since the electrode opening 18 must expose the electrodes of the weight scale 1, it is necessary to make a hole.

The decorative sheet 2 is preferably a decorative sheet with a total thickness of 0.4 mm or more and 1.2 mm or less, which is lined with a synthetic resin sheet with a thickness of 0.25 mm or more and 1 mm or less. The surface material must have surface resistance suitable for flooring, and various decorative sheets used as flooring can be used. The backing material is a synthetic resin sheet with a thickness of 0.25 mm or more and 1 mm or less, and the material is not particularly limited. For example, a polyethylene terephthalate resin film (PETG) with a thickness of 350 μm is preferably used. It is desirable that the decorative sheet lined with a synthetic resin sheet has enough rigidity to float in the air without contacting the partition plate around the scale over a width of 30 mm or more.

The surface material of the decorative sheet 2 may be of the same material and design as that used for the floor material 6 at the installation location, or may be of a different color tone or pattern. It can be a single color sheet or it can have a pattern. Further, the surface may be coated with antibacterial and antiviral coatings.
A partition board that houses the scale and is covered with a decorative sheet is attached to the inner frame of a commercially available underfloor inspection port. To install, follow the installation procedure for the underfloor inspection port, and fix the inner frame and partition plate with screws. Since the decorative sheet 3 moves outward during weight measurement, it is attached so that the end of the decorative sheet does not come into contact with the wall surface of the inner frame 4. The outer frame of the underfloor inspection port can be installed using the general construction method for underfloor inspection ports without any problems.
You can attach square timbers or place sturdy storage boxes under the floorboards to safely catch the partitions should they fall. You can also cover the opening with insulation material.

FIG. 5 is a cross-sectional explanatory diagram showing an example of a method for fixing the weight scale 1 to the partition plate 3. As shown in FIG. By fixing the scale 1 to the partition plate 3, it is possible to prevent the scale 1 from falling over. In this example, the top plate of the scale 1 and the partition plate 3 are connected by wires 10 at four or more locations without pulling the scale or loosening it. In this example, the wire 10 comes out from the wire hole 13 to the lower surface of the partition plate 3 and is fixed to the partition plate 3 with a fixing screw 11. As a result, even if you put your weight on the edge of the top of the scale, the wire will prevent the other side from lifting up, so the scale will not tip over. Furthermore, since the wire 10 loosens when measuring the weight, it does not adversely affect the measured value. If there is sufficient clearance between the scale and the partition plate, the wire 10 may be fixed onto the partition plate on which the scale is placed.

There are no particular restrictions on the material of the wire 10, and materials with low elongation, such as steel wire, piano wire, metal chains, and nylon strings, can be used.
There are no particular restrictions on the method of fixing the weight scale 1 to the partition plate 3, and although not particularly shown, the weight scale may be directly fixed to the partition plate 3 using fixing screws from the back side of the partition plate 3, for example. If the double-sided tape is strong enough, you can also fix the back of the support legs of the scale with the partition plate and double-sided adhesive tape.

FIG. 4 is an explanatory plan view showing a state in which the decorative sheet 2 is fixed with the pins 15. In this example, pins 15 inscribed in the inner frame 4 are provided at the four corners of the underfloor inspection opening inner frame 4, and pin holes 16 are provided in the decorative sheet 2 to allow the pins 15 to pass through. It is characterized in that the outside of the pin 15 and the outside of the pin hole 16 are arranged so as to be in contact with each other on the diagonal line of the frame 4. By doing so as well, it is possible to prevent the weight scale 1 from falling over. Since the pin 15 and the pin hole 16 are in contact with each other on the outside, movement of the decorative sheet 2 is regulated by the pin 15. Therefore, even if weight is applied to the edge of the scale 1, the decorative sheet does not move inward, which prevents the opposite side of the scale from being lifted up and prevents the scale 1 from tipping over.

Since the pin 15 is installed in contact with the inner frame 4 of the underfloor inspection port, there is no risk of tripping if the pin is at a height equal to or less than the height of the inner frame. Further, the decorative sheet 2 will not come off. Further, during normal weight measurement, the decorative sheet 2 moves outward, so the pin 15 is no longer regulated. Therefore, the regulation of the decorative sheet 2 by the pin 15 does not adversely affect the weight measurement.
