Description

  The present invention relates to a floor embedded structure of a scale.

  Weight measurement in a general home is performed by placing a scale on the floor and riding it on it. However, since the scale has a certain height, if it is placed on the floor when not in use, it may trip or kick, but it is very troublesome to put away. In view of this, it is conceivable to install the scale in an embedded state at a predetermined position on the floor.

  By the way, when placing the weight scale in a floor-embedded state, a cover plate is provided with a recess for installing the weight scale on the floor surface, the weight scale is installed on the bottom surface of the recess, and the upper surface of the weight scale is closed. However, in that case, the cover plate should be provided in such a way that it does not protrude toward the floor so that vertical displacement during weight measurement is allowed. It is necessary to keep it.

  However, there are various plane sizes of the scale, and if a scale with a small plane size is installed in the center of the bottom of the recess, the cover plate will protrude to the side of the scale in the plane of the recess, and the weight will be reduced. If the overhanging part is accidentally stepped on at the time of measurement, the cover plate or the weight scale is inclined, which is dangerous, and the weight scale may be damaged due to impact force.

  In addition, in the structure where the cover plate is attached depending only on the scale, if a force in the side-sliding direction or a force to disengage upward acts on the cover plate, it also acts strongly on the scale, In addition, there is a problem that a large mechanical load is applied and it is easy to cause a failure.

  In view of the above problems, an object of the present invention is to provide a floor-embedded structure of a weight scale that can be used safely and does not cause the weight scale to malfunction.

A scale having a plane size smaller than the plane size of the recess is installed at the center of the bottom of the recess,
On the upper surface of the scale, a cover plate that closes the recess is installed in a manner that protrudes laterally from the scale but does not protrude to the floor surface side,
A scale that allows the cover plate to tilt toward the bottom surface of the recess while allowing the vertical displacement of the cover plate during weight measurement between the side protruding portion of the cover plate and the bottom surface of the recess. The invention is solved by a floor embedding structure of a weight scale, which is provided with a tilt prevention mechanism portion for preventing without depending on (first invention).

  In this structure, an inclination prevention mechanism for preventing the cover plate from tilting toward the bottom surface of the recess without depending on the scale is provided between the side protruding portion of the cover plate and the bottom surface of the recess. So, even if you accidentally stepped on the cover plate's side overhang when measuring weight, the anti-tilt mechanism works to prevent the side overhang from tilting, It is possible to safely measure the weight and prevent the scale from being broken.

  In the first invention, the skid that prevents the skid of the cover plate without depending on the scale while allowing the cover plate to be displaced in the vertical direction between the laterally protruding portion of the cover plate and the bottom surface of the recess. The prevention mechanism part is good to be provided (2nd invention).

  In this case, when a force in the skid direction acts on the cover plate, the skid mechanism prevents the skid of the cover plate, and the skid mechanism prevents the skid of the cover plate without depending on the scale. Since it is made to prevent, there is little or almost no mechanical load on the weight scale at that time, and the weight scale will not be damaged. In addition, the side slip prevention mechanism is effective in the space between the laterally protruding part of the cover plate and the bottom part of the recess, while the plane size of the scale is set smaller than the plane size of the recess. Since it is provided and utilized, it is possible to easily incorporate the skid prevention mechanism.

  Further, in the first and second inventions, the weight of the cover plate is prevented from coming off upward while allowing the cover plate to be displaced in the vertical direction between the side protruding portion of the cover plate and the bottom surface of the recess. It is preferable that a disengagement prevention mechanism portion for preventing without depending on the above is provided.

  In this case, when a force in the upward disengagement direction acts on the cover plate, the disengagement prevention mechanism portion prevents the cover plate from coming off upward, and the disengagement prevention mechanism portion does not depend on the scale. Since the cover plate is prevented from coming off, there is little or almost no mechanical load on the scale at that time, and the scale is not damaged. In addition, the detachment prevention mechanism has an effective space between the laterally protruding part of the cover plate and the bottom part of the recess while the plane size of the scale is set smaller than the plane size of the recess. Since it is provided and utilized, it is possible to easily incorporate the detachment prevention mechanism.

Moreover, the present invention is provided with a recess for weight scale installation on the floor surface,
A scale having a plane size smaller than the plane size of the recess is installed at the center of the bottom of the recess,
On the upper surface of the scale, a cover plate that closes the recess is installed in a manner that protrudes laterally from the scale but does not protrude to the floor surface side,
A skid prevention mechanism that prevents lateral displacement of the cover plate without depending on the scale while allowing the displacement of the cover plate in the vertical direction between the laterally projecting portion of the cover plate and the bottom surface of the recess. A floor-embedded structure for a scale (fourth invention) is provided.

  Next, the best mode for carrying out the present invention will be described with reference to the drawings.

  In the weight scale floor embedding structure of the embodiment shown in FIG. 1 to FIG. 5, reference numeral 1 denotes a floor surface such as a toilet or a wash-dressing room, and a rectangular recess 2 for installing a weight scale is provided on the floor surface 1. The weight scale 3 is installed in the center of the bottom of the recess 2.

  As shown in FIGS. 4 and 5, the recess 2 has a hole 4 that opens below the floor on the floor surface 1, and a scale 5 support plate 5 that extends from below to the joist 6. A water receiving rod 7 having an outwardly projecting shoulder portion 7 a is integrally attached to the upper surface side of the peripheral portion of the plate 5, and the shoulder portion 7 a is provided around the hole 4. It is formed so as to cover the floor surface 1, and the planar size is designed to be a size that allows both human soles to fit without protruding toward the floor surface, for example, a size of 330 mm on one side. In FIG. 2 (a), 8 ... are load transmission bolts for transmitting part or all of the load applied to the scale support plate 5 to the joist 6.

  The weight scale 3 has a plane size that is considerably smaller than the plane size of the recess 2, and is installed in the center of the bottom surface 2 a of the recess 2 as shown in FIG. 4. In the section, a cover plate 9 having a planar view shape that covers the recess 2 in a manner that protrudes laterally from the weight scale 3 but does not protrude to the floor surface 1 side is installed.

  The cover plate 9 is composed of three plates 11, 12, and 13. The lower and middle plates 11 and 12 are base plates made of metal, and the uppermost plate 13 is a finishing plate. . The lowermost plate 11 is lightly fastened to the upper surface portion of the weight scale 3 with a hook-and-loop fastener 14, and the intermediate plate 12 is overlapped with the upper surface portion of the lowermost plate 11 so as to overlap the surface fastener. 14, the uppermost finishing plate 13 is lightly detachably fastened with a hook-and-loop fastener 14 so as to overlap the upper surface of the intermediate plate 12 in the same manner.

  In order to prevent the above-described three-type cover plate 9 installed on the weight scale 3 from being tilted, prevented from slipping, and prevented from coming off upward, the following configuration is employed.

  That is, as shown in FIG. 2 (b), the lowermost plate 11 is provided with horizontal ears 15 eccentrically formed stepwise at the four corners by press molding, and each side part. Are provided with reinforcing rising portions 11a..., And each ear portion 15 is provided with a through hole 16.

  Further, as shown in FIGS. 2 (a), 1 and the like, in the bottom surface portion 2a in the recess 2, pedestals 17 are fixed at heights away from the bottom surface 2a by a predetermined dimension at the four corners. The pedestal 17 is provided with a screw hole 18. In addition, there is no restriction | limiting in the form of the base 17, and it does not need to be a leg type thing as shown in figure.

  The lowermost plate 11 is placed on the upper surface portion of the weight scale 3, and the ear portion 15 is kept separated from the upper surface portion of the pedestal 17 as shown in FIG. From above, a bolt 20 with a packing 19 is passed through the through hole 16 of the ear 15, and the bolt 20 is screwed into the screw hole 18 of the base 17. The packing 19 is connected to the bolt 20 and the ear. It is in a state of being interposed between the periphery of 15 through holes 16. The through hole 16 is loose with respect to the packing 19 and is formed in a hole smaller than the bolt head 20a. By making the through hole 16 loose with respect to the packing 19, movement in the side-sliding direction can be elastically blocked by the packing 19, and wear of the packing 19 can be prevented.

  The intermediate plate 12 in the cover plate 9 projects above the stepped portion of the ear portion 15 of the lowermost plate 11 and functions as a base that supports the uppermost plate 13 from below above the bolt head 20a.

  In the above weight scale floor embedded structure, for example, when the weight is accidentally stepped on the side protruding portion 10 of the cover plate 9, as clearly shown in FIG. The ear portion 15 of the lowermost plate 11 located on the opposite side is engaged with the bolt head portion 20a and is prevented from being lifted, so that the cover plate 9 is inclined to the side where it has been stepped on strongly. Is prevented. The ear 15 may or may not be tilted by contacting the pedestal 17. Bolts 20, ears 15 and pedestals 17 are provided at four locations in the circumferential direction, so that no matter where you step on the side projection 10 of the cover plate 9 in the circumferential direction, it will not tilt and you can safely measure your weight. Can be done. And this inclination prevention is made by engaging the bolt 20 and the ear | edge part 15, Comprising: It depends on the weight scale 3 dynamically, ie, a weight scale itself does not tilt. Therefore, the weight scale 3 is not mechanically damaged and does not break down. Therefore, the weight scale 3 may be in an installed state in which the weight scale 3 is simply placed on the bottom surface 2 a of the recess 2.

  Further, even when a force in the side-sliding direction acts on the upper surface portion of the cover plate 9, the peripheral portion of the through-hole 16 of the ear portion 15 of the lowermost plate 11 is the packing 19 as is apparent in FIG. Is engaged with the shaft portion of the bolt 20, thereby preventing the cover plate 9 from sliding sideways. Since the bolts 20 and the ears 15 are provided at four locations in the circumferential direction, the cover plate 9 can be applied regardless of which side slip force acts on the cover plate 9 or the torsional side slip force. 9 will not skid. The slip prevention is performed by the engagement of the bolt 20 and the ear portion 15 and is mechanically dependent on the weight scale 3, that is, the weight scale itself does not skid. Therefore, the weight scale 3 is not mechanically damaged and is not damaged.

  Further, even when a force in the upward direction is applied to the cover plate 9, as is apparent from FIG. 1B, the ear portion 15 of the lowermost plate 11 is engaged with the bolt head portion 20a. , And the cover plate 9 is prevented from shifting upward. This disengagement prevention is performed by the engagement of the bolt 20 and the ear part 15 and is mechanically dependent on the weight scale 3, that is, the weight scale itself does not rise. Therefore, the weight scale 3 is not mechanically damaged and is not damaged.

  When maintenance or replacement of the scale 3 is performed, if the upper and middle plates 12 and 13 of the cover plate 9 are removed, the bolts 20 at the four corners are removed, and the lowermost plate 11 is removed. The weight scale 3 in the body 2 can be taken out, and repair can be performed in the opposite manner, so that the weight scale 3 can be easily maintained and replaced.
