Description

[Detailed description of the invention] The present invention relates to a platform scale in which the sheet of the platform scale is replaceable.It is an object of the present invention to provide a platform scale in which the sheet can be freely replaced according to preference, and the sheet surface has a good texture. be.

Embodiments will be described in detail below with reference to the drawings.

1 is a platform scale. This platform scale 1 consists of a base 2 and a cover 3. A conventional weighing mechanism (not shown) is installed inside the base 2, and a cover 3 is placed on this weighing mechanism, leaving only a central portion 3a. , a concave surface 3b is provided on both sides of the cover 3, a display window 3c is provided in front of the center portion 3a, and a locking hole 3d is provided in the rear portion of the center portion 3a. This is a so-called flat weight scale that rotates a scale plate 4 and displays a weight value commensurate with the body weight on a display window 3c.

Note that the recessed portion surface 3b may be entirely depressed without leaving the central portion 3a, or may be a flat surface.

5 is a cushion material. This cushion material 5
is made of a flexible and elastic material such as sponge, and has the same shape as the concave surface 3b provided in the cover 3,
The thickness t is thicker than the depth t' of the recessed surface 3b,
It is fitted onto the recessed surface 3b.

6 is a sheet. This sheet 6 is the display window 3c
A relief hole 6a and a relief hole 6b of the locking hole 3d are provided,
The material is a flexible sheet such as cloth,
The instructions for this platform scale serve as a paper pattern, and the user can freely make as many scales as they like according to this paper pattern. The sheet 6 has the escape hole 6a as the display window 3c,
It is placed on the cushion material 5 with the escape hole 6b aligned with the locking hole 3d (FIG. 2).

7 is a sheet holding frame. This sheet presser frame 7
is formed by integral molding, and has apertures 7b of a similar shape slightly larger than the cushion material 5 on both sides of the intermediate part 7a, and a downwardly directed tip 7c/1 is sharply formed around the aperture 7b. Protrusions 7c are formed at appropriate intervals, and a window hole 7 is formed in the upper part of the intermediate part 7a.
d, and a drop-in part 7e into which a part of the intermediate part 7a is sunk is provided at the bottom, a rotatable knob 8 is engaged in the middle of this drop-in part 7e, and a knob 8 is engaged under the front side wall. A matching claw 7f is provided. After the sheet 6 is placed on the cushion material 5, the sheet holding frame 7 engages the engaging claw 7f under the front side wall of the cover 3, and aligns the window hole 7d with the display window 3c to position the knob 8. Insert the cushion material 5 while aligning it with the locking hole 3d.
The tip 7c.1 of the protrusion 7c is hooked to the surface portion of the sheet 6 located on the outer periphery of the sheet 6, and the sheet 6 is held between the cover 3 and the protrusion 7c so that the hooked portions are pulled together. Rotate the knob 8 approximately 90 degrees and fix it. At this time, the seat surface 6c exposed in the opening 7b is overhanged by the cushion material 5, and the seat surface 6c is slightly raised from the surface 7g of the sheet presser frame 7, and the section around the cushion material 5 is It becomes rounded and the sheet surface 6c has a plump finish.

In addition, as a result of the sheet 6 being used for a long period of time, it may become dirty.
When cleaning the sheet 6 by washing it, or when replacing it with another sheet 6, the operation is the opposite to that used when setting the sheet holding frame 7, that is, the knob 8
90° in the opposite direction to the setting, release the locking piece (not shown) provided at the tip of the knob 8 from the locking hole 3d, and while raising the sheet holding frame 7, press the locking claw 7f.
is removed from the cover 3 and the sheet presser frame 7 is removed.After that, the sheet 6 is removed and washed or replaced with a new sheet 6, and the sheet 6 is installed using the procedure described above for setting.

As described above, the seat surface 6 appearing on the cover 3
c is stretched through a thick cushion material 5, and it is raised one step above the sheet holding frame 7, and the edges are rounded, so it feels fluffy and soft to the touch when weighing, and the finish is soft. Gives a soft appearance.

In addition, the sheet 6 can be freely manufactured according to one's preference and can be replaced.Furthermore, if the sheet 6 is made of thin material, it is fixed on the cover 3 by hooking it onto the tip 7c/1 of the protrusion 7c. Since the cushion material 5 can be fixed at the tip 7c.1 of the protrusion 7c while holding down the cushion material 5 by that much, there is a degree of freedom in selecting the material of the sheet 6, and the cutting edge around the sheet 6 can be fixed. Since it is hidden within the sheet holding frame 7, it can be cut as appropriate, making it very practical.
