Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a horizontal adjustment tool for correcting inclination and the like when installing furniture and the like.

[0002]

[Prior art]

 As this type of horizontal adjusting tool, a combination of a bolt and a grounding body is well known as in the present invention (Japanese Utility Model Laid-Open No. 64-35939). In this device, a base body having two mounting flange pieces is screwed to the inside of a side plate of a furniture or the like that is joined at a right angle, and a bolt is screwed into a screw hole in the bottom plate of the base body to adjust the height of furniture or the like. It is designed to adjust the horizontal.

In addition, in order to simplify the method for correcting the inclination of furniture or the like, only the vertical movement is possible in the main body provided with a seat for attaching to the furniture bottom, and the bottom end protruding downward from the main body touches the floor. A rotatable screw shaft that is screwed into a female screw hole provided in a lifting body with a surface and a rotation operation shaft that is orthogonal to the screw shaft are supported and connected to each other via large and small bevel gears. However, there is a complicated structure in which rotary operation parts are provided on the outer end of the rotary operation shaft and the upper end of the screw shaft, respectively, and these operation parts can be operated from the outside of the main body (Actual exploitation 63-75248). Issue).

Further, there is known a structure in which a threaded portion is provided on a projecting portion of a support leg of furniture or the like, and an operation cylinder having an inner peripheral thread groove that is screwed into the threaded portion is rotated so as to be vertically movable. (Actual No. 63-61942).

[0005]

[Problems to be solved by the device]

 However, since the above-mentioned device gives priority to horizontal adjustment after installation of assembled furniture, etc., when installing in a factory etc., insert a tool into the inner surface of assembled furniture and rotate screws. However, there was a troublesome problem of having to rotate and attach the grounding part.

An object of the present invention is to provide a leveling tool for furniture or the like that can be easily mounted on the assembly line of a factory or the like.

[0007]

[Means for Solving the Problems]

 A configuration of the present invention for achieving the above object will be described with reference to FIG. 1 corresponding to an embedded example. In the conventional leveling tool for furniture or the like, the bolt 1 is screwed and locked to the male screw 8 provided on the mounting plate 7 fixed by welding or screwing to the lower frame 6 of the furniture or the like. Although 15 is rotated from the hill with a tool so that the grounding body 2 can be housed in the lower frame 6, the bit frame 14 is also provided at the other end of the bolt 1 so that the lower frame 6 The bolt 1 can be screwed and locked to the male screw 8 of the mounting plate 7 from the outside.

[0008]

[Action]

 The bolt 1 has a bit hole 15 at one end, and the washer 3 and the grounding body 2 are inserted into the step portion 12 at the other end to deform the end face 13 under pressure and at the same time form the bit hole 14, thereby forming a lower frame. It becomes possible to screw the bolt 1 into the mounting plate 7 from inside and outside of 6. Generally, the inclination of the furniture or the like is corrected from the outside of the lower frame 6 to be attached to the mounting plate 7 and from the inside of the lower frame 6 when the assembled furniture or the like is installed.

[0009]

【Example】

 In FIG. 2, 1 is a bolt, 2 is a grounding body, and 3 is a reinforcing washer. A bolt hole 15 is provided at one end of the bolt 1 as in the conventional case, and a step portion 12 formed to be finer than the female screw portion 11 is provided at the other end, and the washer 3 and the grounding body 3 are inserted in this step portion 12 in this order. However, a grounding surface 21 is provided at the lower end of the grounding body 2 so as to be in contact with the floor surface in parallel, a hole into which the upper end of the grounding body 2 can be inserted in the stepped portion 12 of the bolt 1 is formed, and the outer periphery is formed into a substantially bell shape to ensure strength. Has been done.

The washer 3 and the grounding body 2 are inserted into the stepped portion 12 of the bolt 1 in order and fixed to the female mold 5 so that they cannot swing, and the male mold 4 allows the washer 3 and the grounding body 2 to swing. 12, the male die 4 is provided with a deformation processing portion 42 and a bit-shaped portion 41, and the end face 13 of the step portion 12 is deformed by pressure and the bit hole 14 is formed. The pressure deformation does not cause the grounding body 2 and the washer 3 to be rockable between the step portion 12 of the bolt 1 but can be rocked while the grounding body 2 is in contact with the floor surface. It should be transformed into. This is to ensure that the ground contact surface 21 is always level with the floor surface (Figs. 3 and 4).

In FIG. 5, the horizontal adjustment tool attached to the lower frame 6 of furniture or the like is rotated by inserting the tip of the tool into the bit hole 15 of the bolt 1 through a hole formed in the bottom plate 9 inside the furniture or the like. When this is done, the furniture, etc. will move up and down, the inclination of the furniture, etc. will be corrected and it will be possible to install it horizontally to the floor. Further, if the furniture or the like is laid down at the time of assembling the furniture or the like, it can be easily screwed into the female screw 8 of the mounting plate 7 from the lower side of the furniture or the like with a tool.

[0012]

[Effect of device]

 As described above, according to the present invention, by providing the bit holes 14 and 15 at both ends of the bolt 1, it becomes easy to attach the lower frame 6 of furniture or the like, and the grounding body 2 is attached to the floor of the bolt 1. The washer 3 is incorporated so as to be swingable depending on the state of the surface, and has the function of reinforcing the bolt 1 and the grounding body 2 and preventing friction during the swinging and making the swinging smooth.
