Abstract

PURPOSE:To eliminate a step difference generated between free access floor panels butted and supported on a support leg. CONSTITUTION:In a free access floor constituted by supporting corner parts of adjacently laid and juxtaposed floor panels 1a and 1b in common on a panel receiving seat 4 of a support leg A, for example, a sheet like spacer B formed by applying a pressure sensitive adhesive to the reverse of a fibrous sheet impregnated with rubber latex or or a gluey substance, is stuck on a cushion material 6 contacting with the panel 1a necessary to adjust a step difference, and a step difference between the panels is adjusted. Since the sheet like spacer B is fixed to the support leg side by a sticking action, the spacer does not move when the floor panel is removed. The spacer can be easily removed according to its necessity.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a free access floor, and more particularly, to an improvement of an adjusting device capable of eliminating a step generated between free access floor panels that are placed in abutment with each other on support legs. Regarding

[0002]

2. Description of the Related Art In the floor of an electronic computer room or an OA room, a large number of supporting legs are erected in a grid pattern on a foundation floor, and the corner portions of adjacent floor panels are butted against each other on the supporting legs. A floor structure called a free access floor configured by being placed is widely adopted. The support legs used for this type of floor structure are usually adjustable in height, but even if the height of the support legs is adjusted, mainly due to variations in the thickness of the floor panel, etc. A minute step may occur between floor panels placed on the supporting legs in abutment with each other. Conventionally, such a fine step adjustment is generally performed by interposing a spacer between the floor panel and the support leg.

[0003]

However, this type of spacer is often mounted on the supporting leg without being fixed. In such a case, the floor panel is removed when the layout is changed. It will move when the floor panel is placed and it will be necessary to readjust it when placing the floor panel.

Further, it is desirable that this kind of spacer has appropriate flexibility and elasticity from the viewpoint of walking sensation, and that the compression restoring force does not decrease due to long-term use. Is desirable. Furthermore, it is desirable that the OA equipment on the floor is not easily charged with static electricity so as not to cause electrostatic damage.

[0005]

OBJECTS OF THE INVENTION The present invention is capable, and necessary, of retaining spacers provided to eliminate steps created between free-access floor panels abutted against each other on support legs. It is a main object of the present invention to provide a level adjuster for a free access floor whose spacer can be easily removed according to the above.

[0006]

In the level adjusting device for a free access floor of the present invention, a large number of support legs are erected in a grid pattern on a foundation floor, and the corner portions of adjacent floor panels are located above the support legs. In a free access floor configured by being placed against each other, a sheet-shaped spacer in which an adhesive is applied to the back surface of a fibrous sheet impregnated with rubber latex or a colloidal substance is provided on the support leg. It is characterized in that a step generated between the floor panels which are abutted against each other on the support legs and placed on each other is adjusted by the attachment.

In the structure of the present invention, the rubber latex used to impregnate the fibrous sheet used for the sheet-like spacer is preferably NBR rubber latex or SBR rubber latex, and the colloid substance is preferably gelatin or glue. In addition, since the fibrous sheet is generally easily charged by friction, the fibrous sheet used for the sheet-like spacer used in the present invention is preferably subjected to an antistatic treatment. The antistatic treatment is conveniently performed by impregnating a surfactant.

[0008]

The level adjusting device for a free access floor according to the present invention has a structure in which a sheet-like spacer having a back surface coated with an adhesive is attached to the support leg, so that the spacer is fixed to the support leg by the adhesive. The spacer does not move when the floor panel is removed. Moreover, the spacer can be easily removed if necessary.

Further, since the sheet-like spacer used in the present invention is a fibrous sheet impregnated with rubber latex or a colloidal substance, the rubber latex or the colloidal substance imparts appropriate flexibility and elasticity. In addition, the walking feeling on the free access floor is not hindered, and the function of the fibers does not reduce the compression restoring force after long-term use. Further, the fibrous sheet used for the sheet-shaped spacer is subjected to antistatic treatment, so that electrostatic trouble of OA equipment on the floor can be prevented.

1 to 3 show an embodiment of the present invention. In the figure, 1a, 1b, 1c and 1d are floor panels that are laid side by side, and A is a grid pattern on the foundation floor so that the floor panels that are laid side by side can be commonly supported at their corners. It is a support leg that is erected in a shape. The support leg A is composed of a fixed plate 2 fixed on the base floor, a height-adjustable support column 3 standing on the fixed plate 2, and a panel seat 4 attached to the upper end of the support column 3. ing.

Further, the panel seat 4 is provided with a ridge 5 for restricting the position of the floor panel, and a cushion member 6 is attached to the upper surface thereof. Then, the cushion material 6 supports the panels 1a, 1b, 1 supported by the support legs.
Of c and 1d, the panel 1a that requires adjustment of the step
A sheet-shaped spacer B for adjusting a step is attached on the cushion material 6 that hits against.

Sheet-shaped spacer B for adjusting the step
As shown in FIG. 3, after impregnating an impregnating liquid consisting of an aqueous solution of a mixture of gelatin, glue, ethylene glycol, and a surfactant into an organic fiber base paper having excellent water absorption, the impregnating liquid is gelated. The adhesive 8 is applied to the back surface of the fibrous sheet 7. 9 is a release paper, which is peeled off when the spacer is used.

It is easy to handle the spacer B having the above-mentioned structure if the adhesive 8 is applied to the back surface of the fibrous sheet 7 in advance at the stage of being manufactured in the factory, and the release paper 9 is further attached. Further, as shown in FIG. 4, if the spacer B is made by semi-punching the spacer material B ′, it is not necessary to cut it out at the work site and it is easier to handle.

[0014]

In the level adjusting device for a free access floor of the present invention, a sheet-like spacer having a back surface coated with an adhesive is affixed to the support leg, so that the spacer is fixed to the support leg and the floor panel is fixed. The spacer does not move when the is removed. Moreover, the spacer can be easily removed if necessary. Further, since the sheet-like spacer used in the present invention uses a fibrous sheet impregnated with rubber latex or a colloidal substance, it has appropriate flexibility and elasticity,
The walking feeling on the free access floor is not hindered, and the compressive restoring force of the spacer does not decrease with long-term use. Furthermore, by using a fibrous sheet that has been subjected to an antistatic treatment as the sheet-shaped spacer, electrostatic damage of OA equipment and the like on the floor can be prevented. In addition, the spacer can be made easy to handle by having an adhesive applied to the back surface and release paper attached at the stage of being manufactured in the factory, and by making it half-punched. .
