Description

[Detailed explanation of the invention] (Industrial application field) This invention consists of a single leg that supports the table,
In particular, it relates to a mounting structure for removable legs.

(Prior Art) Conventionally, a table has been supported by a plurality of legs, and the legs have been either fixed to the table or removable. In addition, when the table is supported by one leg, as shown in Fig. 1, the table c is supported by a leg a and a plurality of arms b integrally attached to the leg a. , the table d is placed on the mounting plate c, and as shown in FIG. There was something stuck on the back. Furthermore, as shown in FIG. 3, a rotating tool f that is L-shaped and has an arc-shaped rotation guide hole bored in its hanging piece is fixed to the back surface of the table d, and the leg a is attached to the rotating tool f. The table d can be tilted by pivotally mounting the table d and the rotating tool f is fastened to the leg body a with fixing bolts, or the leg can be bent by having a tilter h as shown in Fig. 4. body a
is fixed to a table d, and the table d can be tilted by adjusting the engagement of the tilter h.

However, with the conventional structure in which the table is supported by a single leg as described above, the table is unstable if the table is placed on a mounting plate, and the table does not have fixing fittings, rotating tools, and tilters. In a structure that can be rotated or tilted through the table, the mounting area of the fixing bracket or rotating tool is small, so the load of the table or the item placed on the table is concentrated on the mounting area of the fixing bracket or rotating tool. There was a drawback that the attachment part could be crushed or broken.

(Purpose of the invention) This invention was made in consideration of the above-mentioned drawbacks of the conventional technology.It allows a single leg to support a table over a wide area without causing any wobbling, and also allows the table to be easily attached and removed. The purpose is to make the work easier.

(Structure of the invention) The leg mounting structure according to this invention, which was made to achieve the above-mentioned object, is a single structure having a pair of engaging ribs fixed to the back surface of the table and facing each other in a V-shape. a catch plate; a fan-shaped insertion plate that engages with the engagement rib so as to be movable in a predetermined insertion direction along the lower surface of the catch plate; a single leg; a back surface of the insert plate; and an upper part of the leg. a rotating tool rotatably connecting the
A table leg mounting structure in which the table is supported by a single leg, which screws into a hole drilled in the insertion plate, and when tightened, the tip of the table leg attaches to the top of the insertion plate. A vertical bolt that can be freely retracted and retracted is inserted through a long arc-shaped hole drilled in the rotary tool and the upper end of the leg body, and is screwed into the thumbscrew, and when tightened, the insertion plate is inserted into the leg. The device is characterized by comprising a fixing bolt that fixes the device in a desired inclination state with respect to the body.

(Example) Next, this invention will be explained in detail based on an example shown in FIGS. 5 to 10.

In the figure, reference numeral 1 denotes a catch plate, which is fixed to the approximate center of the back surface of the table by screws or rivets at its four corners, and its top surface is joined to the back surface of the table. Further, as shown in FIG. 6, the side edge of the catch plate 1 is folded back to have a U-shaped cross section, and is provided with a pair of engaging ribs 10 that are arranged opposite each other in a V-shape. 2 in the figure is an insertion plate, and the catch plate 1
When the insertion plate 2 is placed on the lower surface of the catch plate 1 and slid in the insertion direction (direction of arrow A in the figure), the engagement ribs The insertion plate 2 is fitted into and held by the insertion plate 10. As shown in FIGS. 7 and 8, a pair of L-shaped rotating tools 3 are provided on the back surface of the insertion plate 2.
are fixed via rivets, and the hanging pieces 30 of the rotary tool 3 face in the insertion direction (direction of arrow A in the figure).

The hanging piece 30 holds the upper end of the leg body 4 and is rotatably pivoted via the shaft g. Furthermore, as shown in FIG. 8, each hanging piece 30 is provided with an arc-shaped elongated hole 31 centered on the axis g, and the upper end of the leg 4 is inserted through the elongated hole 31. By tightening the penetrating fixing bolt 5 with a wing screw, the insertion plate 2 can be fixed to the leg body 4 in an inclined state. In the figure, reference numeral 6 denotes a vertical bolt which is screwed into a hole 20 formed at the rear end of the insertion plate 2 and whose tip can freely move upward and out.
When the vertical bolt 6 is tightened after the insertion plate 2 is attached to the catch plate 1, its tip abuts against the catch plate 1 in a pressed state to fix the insertion plate 2, and is held by the engagement rib 10. This prevents the insertion plate 2 from moving in the horizontal direction or in the vertical direction.

In addition, in the above-mentioned catch plate, the side edge is folded back to form the engagement rib, but a pair of members provided with an L-shaped cross section are arranged oppositely in a V-shape on the back side of the catch plate and fixed. , a pair of engaging ribs may be formed.

(Effects of the invention) As explained above, according to this invention, the entire upper surface of the catch plate receives the weight of the table and the items placed on the table, so that it can be used not only when the table is horizontal but also when it is tilted. Also, the load is not concentrated on the back surface of the table, and the stability of the table is improved. Furthermore, the legs can be attached and detached simply by sliding the insertion plate relative to the catch plate, making assembly and disassembly easier. Furthermore, even when the table and legs are disassembled, there are no protrusions on the back surface of the table, making it easy to transport and handle. The insertion plate is fixed by the simple operation of tightening the vertical bolts provided on the insertion plate, and the wedge effect on the outer line of the insertion plate and the tightening effect of the vertical bolts prevent loosening or wobbling between the insertion plate and the catch plate. It has excellent practical effects, such as being able to prevent abnormal noises from occurring.
