Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a device for fixing a height-adjustable support leg screwed to a leg or a bottom of a support object such as furniture or equipment to a floor surface. It is a thing.

[Prior Art] Conventionally, in order to fix a height-adjustable support leg to a floor surface, a through hole is provided in a central horizontal plate portion of a strip plate bent in a substantially trapezoidal shape, and lower end portions of inclined plate portions on both left and right sides are provided. A holding metal fitting with a vertical hole is used in the horizontal overhanging plate part of.

In use, the support tube of the support leg is fitted into the through hole of the retainer, and the fixing bolt inserted into the vertical hole is screwed into the floor surface.

[Problems to be Solved by the Invention] In this press fitting, the inclined plate portion and the horizontal overhanging plate portion largely protrude to the outside of the supporting leg, so that there is a drawback that a large installation space is required. Also, the horizontal overhanging plate exposed on the floor and the fixing bolts not only make the appearance look bad,
It also interferes with floor cleaning and walking.

Therefore, the object of the present invention is to provide a height-adjustable support leg that does not have a large overhanging portion outside the support leg, has a good appearance and requires a small installation space, and does not interfere with floor cleaning or walking. Is to provide a fixing device.

[Means for Solving the Problems] Hereinafter, referring to the reference numerals in the accompanying drawings, a fixing device for a height-adjustable support leg of the present invention is a recess into which a lower end portion 4a of a support tube 4 of the support leg is fitted. 8a is provided on the upper surface, a vertical hole 10 is provided at a portion hidden by the support cylinder 4, and a pedestal 8 having a male screw portion 9 provided on the outer peripheral surface of the cylinder wall portion 8b and a through hole into which the support cylinder 4 is inserted. A female screw portion 1 provided with 13 in the central portion of the upper surface plate portion 14a and screwed onto the male screw portion 9 on the inner peripheral surface of the cylindrical wall portion 14b.
5 is provided with the cap 14 and the vertical hole 10 causes the floor surface 16
And a fixing bolt 12 that is screwed into.

[Operation] In use, first, the fixing bolt 12 is attached to the base 8
Through the vertical hole 10 and the pedestal 8 is fastened and fixed at a predetermined position on the floor surface 16.

Next, the lower end portion 4a of the support cylinder 4 in which the cap 14 is fitted and placed in advance is fitted into the recess 8a of the pedestal 8.

Finally, the female screw portion 15 of the cylindrical wall portion 14b of the cap 14
Is screwed onto the male screw portion 9 of the cylinder wall portion 8b of the pedestal 8, the cap 14 is attached to the pedestal 8, and the support cylinder 4 is fixed.

The installation height position of the support target 1 is adjusted by rotating the screw rod 3.

[Example] In the illustrated example, the screw bar 3 of the supporting leg is screwed into a vertical screw hole 2 provided in a support target 1 such as various devices, and the lower end portion 3b of the screw bar 3 is a support cylinder. Axial hole 5 in the center of the upper surface of 4
Annular groove 6 that is rotatably fitted to the
A retaining ring 7 is fitted in the. The enlarged diameter portion of the screw rod 3 that comes into contact with the upper surface of the support cylinder 4 is formed in a regular hexagonal cross section and serves as a rotation operation portion 3 a of the screw rod 3.

One vertical hole 10 is provided at the center of the pedestal 8. A nut 11 into which a fixing bolt 12 is screwed is embedded and fixed to a concrete floor surface 16 on which equipment is installed and fixed. A plate-shaped anchor member 17 is welded to the side surface of the nut 11.

When the floor surface 16 is formed of a metal plate, a screw hole for screwing the fixing bolt 12 can be formed in the metal plate.

In this embodiment, the lower end portion 4a of the support tube 4 of the supporting leg is bent in an outer brim shape, and when the cap 14 is sufficiently screwed onto the pedestal 8, the upper surface plate portion 14a of the cap 14 is placed above the lower end portion 4a. It abuts against the end face, which prevents the support cylinder 4 from moving upward.

[Advantage of the Invention] As described above, in the fixing device for the height-adjustable support leg of the present invention,
The lower end portion 4a of the support cylinder 4 of the support leg is fitted into the recess 8a of the pedestal 8, and the fixing bolt 12 to the floor surface 16 is inserted through the vertical hole 10 provided in the portion hidden by the support cylinder 4 to insert the cap. 1
4 through the through hole 13 in the center of the upper surface plate portion 14a.
To the female screw portion 1 of the cylindrical wall portion 14b of the cap 14.
Since 5 is screwed into the male screw portion 9 of the cylindrical wall portion 8b of the pedestal 8,
There are no large overhangs on the outside of the supporting leg, so the appearance is good and the installation space is small, so there is no obstacle to cleaning the floor or walking.
