Description

[Detailed description of the invention] As a device for adjusting the level and wobbling of furniture installed on uneven floor surfaces, screw holes are installed at key points of the inward horizontal bent pieces connected to the lower end of the side panels of furniture, etc. There is a simple device in which a protruding screw rod is screwed into the center of the upper surface of a horizontal pedestal, but in this device, the cantilevered horizontal bent piece was easily bent by vertical loads.

As a device that solved this drawback, Utility Model Publication No. 54-4396
There is an apparatus disclosed in No. 7.

However, this method involves cutting vertical grooves and horizontal holes that are perpendicular to each other in the lower part of the side panels of the furniture, and cutting the bottom of the horizontal holes vertically.
It is necessary to form a support ring, so if the furniture is large,
It has the disadvantage that it is somewhat troublesome to process and also poses some problems in terms of strength.

The present invention aims to improve these points, and will be specifically described below with reference to the accompanying drawings.

At the front lower part of the right side plate 3 of the furniture 2 installed on the floor 1 (lower right side in the drawing), a vertical groove 1 is cut upward from the lower edge of the side plate 3, and at a distance from both the front and rear sides of the groove 1. is the engagement hole 5,
5 is drilled.

Cutouts 6 are cut on both sides of the lower end of the longitudinal groove 4 in the side plate 3, parallel to the lower edge of the side plate 3, and with both ends reaching below the engagement hole 5.5.

Reference numeral 7 denotes a receiving metal fitting, and a nut 9 is fixed to the upper surface of the horizontal receiving piece 8, which is coaxial with a through hole bored in the center.

Upward pieces 10 and 10 are connected to both the front and rear edges of the horizontal receiving piece 8, and each upward piece 10 has a vertical hole 1 extending downward from the center of the upper edge.
1 is cut out, and an engaging protrusion 12 is provided on one side edge of the vertical hole 11 to protrude toward the other side edge.

In the receiving fitting 7, each vertical groove 11 fits into the lower end of the side plate 3,
Each engagement protrusion 12 engages with the engagement hole 5 of the side plate 3, the lower part of the receiving metal fitting 7 fits into the notch 6 of the side plate 3, and the lower ends of the vertical and horizontal 11 are aligned with the upper edge of the notch 6 of the side plate 3. At the same time, the lower portion of the outer surface of each upward piece 10 is in contact with the side edge of the notch 6.

A screw rod 14 protruding from the center of the upper surface of a pedestal 13 whose lower surface is in contact with the floor is screwed into the nut 9 of the receiving metal fitting 7, and the upper part of the screw rod 14 projects into the longitudinal groove 4 of the side plate 3.

According to the device of the present invention described above, when the pedestal 13 is rotated, the receiving bracket 7 whose vertical groove 11 is engaged with the side plate 3 does not rotate, and is rotated along with the furniture 2 relative to the pedestal 13. Go up and down,
It is possible to prevent the furniture 2 from wobbling due to irregularities in the floor surface 1, or to adjust the level of the furniture 2.

As mentioned above, in the device of the present invention, in addition to the longitudinal grooves 4, small engagement holes 5 and notches 6 may be cut in the side plate 3, so that machining is easy and the side plate 3 is No loss of strength.

Further, when attaching the receiving fitting 7 to the side plate 3, the notch 6 guides the receiving fitting 7, so that the engagement between the engaging protrusion 12 and the engaging hole 5 and the positioning of the nut 9 are facilitated.

Furthermore, the engagement of the engagement protrusion 12 and the engagement hole 5 prevents the mounting bracket 7 from moving forward, backward, left or right, and prevents the mounting bracket 7 from falling off even when the furniture 2 is lifted. Since the receiving fitting 7 is fitted into the notch 6, forward and backward movement is doubly prevented.
