Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a floor holder used for holding flooring.

[Conventional technology]

Conventionally, a floor holding tool, as shown in FIG. 3, consists of a floor holding frame 12 that holds flooring, a U-shaped fixing piece A that fixes the floor holding frame 12, and a bottom piece A1 of this fixing piece A. A trapezoidal holding piece C is formed of a horizontal piece C3 and a top wall C1 having a hole C2 into which the lower end of the bolt B is inserted. The bolt B has nuts D1 and D corresponding to the upper and lower parts of the top wall C1 of the holding piece C and the lower part of the fixing piece A.
2, D3 is screwed on.

This floor holder is constructed by installing the horizontal piece C3 on the foundation concrete, loosening each nut D2 and D3, and adjusting the height of the floor holding frame 12 by moving the bolt B forward and backward in the vertical direction. , D3 is tightened. Thereby, the height of the floor material placed on the upper surface of the floor holding frame 12 can be maintained at a predetermined height from the upper surface of the concrete.

[Problem that the invention attempts to solve]

However, in the floor holder with the above configuration, the holding piece C
The nuts D2 and D3 located above and below the ceiling wall C1 are located deeper than the flooring, so they must be operated in an unreasonable posture with the hands extended downward. Therefore, there was a problem that the operation work was not easy.

This idea was created in view of the above problem, and its purpose was to make nut operation easier by operating only the nuts on the floor holding frame side and not needing to operate the nuts located deeper than the flooring. It is an object of the present invention to provide a floor holder that is designed to be used as a floor holder.

[Means for solving problems]

In order to achieve this purpose, this invention integrates the cushion body, and also includes a holding piece with a bolt embedded therein, a fixing piece having a base piece into which the bolt is screwed, and a downward movement of the fixing piece. It is characterized by comprising a nut screwed onto a blocking bolt, a pad installed on a fixing piece, a floor holding frame placed on the pad, and a band surrounding the floor holding frame from above.

[Effect]

In the floor holder configured as described above, the height can be adjusted by operating only the nut located on the base side of the fixed piece, so there is no need to operate the nut located deep from the floor surface. Therefore, there is no need to take an unreasonable posture, and the operation of the floor holder becomes extremely easy.

〔Example〕

This invention will be explained below based on FIGS. 1 and 2 showing one embodiment thereof.

The floor holder according to this invention has a cushion body 1 integrated on the lower surface, and a rectangular plate-shaped holding piece 3 having a screw hole 3c into which a vertical bolt 2 is screwed and installed, and the upper part of the bolt 2 is screwed. A fixing piece 9 having a base piece 5 having a mating screw hole 5a, a nut 10 screwed onto a bolt 2 that abuts the lower surface of the base piece 5 to prevent downward movement, and a nut 10 on the fixing piece 9. It includes a pad 11 to be installed, a longitudinal floor holding frame 12 placed on the pad 11, and a band 14 surrounding the floor holding frame 12 from above.

The cushion body 1 is made of an elastic material such as rubber and has a rectangular shape, and a bolt 2 is located approximately in the center of the cushion body 1.
It has a hole 1a through which it is inserted. This cushion body 1 is fixed to a holding piece 3 formed in the same shape and made of, for example, an iron plate with an adhesive or the like.
In order to securely install the bolt 2, a nut 15 is screwed onto the bolt 2, and this nut 15 presses the holding piece 3. Four rising pieces 6 are provided at the edges of the four sides of the base piece 5. Each rising piece 6 may be formed on at least two opposing sides of the base piece 5 by bending it upward, but here, it is formed on four sides.

The tip of each rising piece 6 is provided with a horizontal piece 8 which is bent outward, and this horizontal piece 8 has a slit 7 parallel to the respective rising piece 6.

Further, the base piece 5 can be moved downward by loosening the nut 10 disposed on the lower side thereof.
When the bolt 2 is tightened, downward movement is prevented.

Further, a pad 11 is installed on the horizontal pieces 8, 8 so as to bridge the upper surfaces thereof. The pad 11 is formed in a rectangular shape and has dimensions such that it does not cover the slit 7.

The floor holding frame 12 placed on the pad 11 is positioned so as to extend in a direction perpendicular to the protruding direction of the two opposing horizontal pieces 8, 8.

A band 14 that surrounds the floor holding frame 12 from above is formed into an inverted U-shape and has locking pieces 13 at both ends thereof.

The locking piece 13 is formed so as to fix the floor holding frame 12 to the horizontal piece 8 by bending outward after being fitted into the slit 7 .

Next, the effect will be explained.

In the floor holder having the above structure, first, the cushion body 1 is installed on the foundation concrete. The height of the fixed piece 9 can be adjusted only by operating the nut 10 and the fixed piece 9. Moreover, Natsuto 10
is arranged at a position close to the flooring, that is, below the base piece 5 of the fixed piece 9.

Therefore, when operating the nut, there is no need to take an unreasonable posture with the hand fully extended downward. Furthermore, since the floor holding frame is attached using the band 14, the overall operation becomes easy.

[Effect of idea]

As explained above, this invention integrates the cushion body, and also includes a holding piece in which a bolt is installed, a fixing piece having a base piece into which the bolt is screwed, and a mechanism that prevents the fixing piece from moving downward. It is characterized by comprising a nut screwed onto the bolt, a pad installed on the fixing piece, a floor holding frame placed on the pad, and a band surrounding the floor holding frame from above. Because of this, the height can be adjusted by simply operating a nut located close to the floor.

Furthermore, the floor holding frame can be fixed by simply inserting the locking piece of the band into the slit and then bending it.

Therefore, work in an unreasonable posture is avoided, making the entire work easier and reducing the time required.
