Description

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention is related to an adjuster for an elevated floor, and especially to such an adjuster for an elevated floor that can lower the height of an assembled elevated floor, and can adjust the height of the elevated floor above the latter; it has a wide range of application, and can reduce waste of space, it is suitable for use in novel and used spaces of offices.

2. Description of the Prior Art

Following advance of science and technology, people contact more and more lines for use; particularly in office buildings, various lines (such as networks and cables) are arranged in a mutually crossing and gathering mode. Therefore, at the initial of construction of an office building, pipelines are embedded in advance; however, the initial planning often is unable to meet the requirement of continuous extension of pipelines afterwards, and pipelines are differently required in different arts.

As to the above stated situation, elevated floors are generally provided; and various pipelines are embedded in channels under the elevated floors. A conventional adjuster for an elevated floor “A” is shown in FIG. 6, which comprises a floor plate “B”; the floor plate “B” is provided with a connecting hole “C” to connect a threaded pipe “D” which has therebeneath a nut “E”, and a footing seat “F” provided on the upper end thereof with a thread is thread connected with the threaded pipe “D” and the nut “E”, thereby the footing seat “F” can be used to adjust height of the floor and then can be fixed by using the nut “E”. The above structure can acquire the function of hiding pipelines; however, it still has the following defects:

• 1. The floor itself has a thickness of about 3 cm, plus the footing seat and the fixing nut beneath the footing seat (about 1.5 cm), an elevated floor after assembling will have a height of at least 6 to 10 cm, and this is the maximum limitation of such elevated floor in assembling and production presently; for a new building preserved with larger heights in space, it will not result a too large problem in space; but for an old building with lower indoor heights originally, it will result waste of space in that the indoor heights will be reduced to make feeling of oppression.
• 2. A conventional elevated floor structure has a footing seat screw connected with the threaded pipe and further has the nut beneath the threaded pipe for fixing the footing seat, when the floor is adjusted to a suitable height, by pressing tight of the nut to fix the footing seat, the footing seat can be avoided from loosening in use to fail in supporting the floor. However, in fixing the footing seat with the nut, an adjustment tool shall be extended in from one side of the floor for adjustment, so that the side of the floor shall be left with a space for extending of the tool therein, and for the convenience of adjusting the nut; the thickness of the nut shall not be too small that may induce inconvenience of adjusting. According to the above stated causes, the height after assembling of the conventional elevated floor is unable to reduce, and adjusting for use of the floor will be quite inconvenient.

In view of the above defects to be solved, an adjuster for an elevated floor not only can have the total height of the elevated floor reduced, but also the elevated floor can have its height adjusted from above the latter; the inventor provides the present invention based on his professional experience of years and continuous studying and developing.

SUMMARY OF THE INVENTION

The primary object of the present invention is to provide an adjuster for an elevated floor, wherein a threaded pipe is thread connected inside with a footing seat and a fixing screw, without to use a nut under the elevated floor, this can reduce the total height of the elevated floor to a degree smaller than 4 cm.

To get the above stated objects, an adjuster for an elevated floor of the present invention is disposed for connected with a connecting hole which is on the elevated floor. The adjuster comprises a threaded pipe, a footing seat and a fixing screw, wherein the threaded pipe has an inner thread for connecting with the connecting hole which is on the elevated floor. The footing seat has an external thread on an external upper end thereof for threading and connecting into said threaded pipe, and further has an adjustment hole on its upper end. The fixing screw is mounted above the footing seat and is thread connected into the threaded pipe, rotation of the screw can press tight the footing seat, the fixing screw has a through hole extended from top to bottom, which is larger than the adjustment hole of the footing seat, so that the adjustment tool can be extended through the through hole and inlaid in the adjustment hole for adjusting the displacement of the threaded pipe relative to the footing seat.

The present invention will be apparent after reading the detailed description of the preferred embodiment thereof in reference to the accompanying drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Referring firstly to FIGS. 1 and 2 showing a preferred embodiment of an adjuster 1 for an elevated floor 2 of the present invention, the adjuster 1 is connected with a connecting hole 21 provided on the elevated floor 2. It comprises mainly: a threaded pipe 3, a footing seat 4 and a fixing screw 5.

A bush 22 is provided between the threaded pipe 3 and the connecting hole 21 on the elevated floor 2, and has an inner hexagonal hole 221. The threaded pipe 3 is in the form of an inversed “T” and has an inner thread 31, and has on the bottom end thereof a circular base 32. The upper portion of the threaded pipe 3 is a hexagonal stub 33 for connecting with the inner hexagonal hole 221 of the bush 22.

The footing seat 4 has a base 41 for standing on the ground, the footing seat 4 is provided on the external upper end thereof with an external thread 42 for threading and connecting with the threaded pipe 3, and the footing seat 4 further has an hexagonal adjustment hole 43 on its upper end.

The fixing screw 5 is mounted above the footing seat 4 and is thread connected into the threaded pipe 3, the fixing screw 5 has a hexagonal through hole 51 extending from top to bottom, the inner tangent circle of the through hole 51 is larger than the outer contact circle of the hexagonal adjustment hole 43 of the footing seat 4.

Referring to FIG. 3 showing use of the present invention, when present invention is used to assemble with the elevated floor 2, the footing seat 4 can be rotated to adjust the elevated floor 2 to a suitable level, then the fixing screw 5 above the footing seat 4 is rotated to move downwards, and the footing seat 4 can be pressed tight for fixing. When the ground is uneven, or the elevated floor 2 needs to be slightly adjusted in height, the fixing screw 5 is loosened, and an adjustment tool (not shown) can be extended through the through hole 51 of the fixing screw 5 from above the elevated floor 2 to be inlaid in the adjustment hole 43 of the footing seat 4 for the convenience of adjusting the displacement of the threaded pipe 3 relative to the footing seat 4, while at the same time, the elevated floor 2 is moved up or down. After the adjustment and positioning, the fixing screw 5 is then rotated to be tight by against the footing seat 4.
