Abstract

PROBLEM TO BE SOLVED: To prevent the occurrence of a shift or a play caused by external forces and to improve reliability by providing lugs on the inner peripheral face side of the oblong holes of L-shaped metal fittings for fixing the main body portions of a unit bath and a shower unit to a building skeleton portion. SOLUTION: L-shaped metal fittings 1, 2 are used to fit a bath unit 4 to a bathroom skeleton portion 3. Multiple lugs are formed at constant intervals on the inner peripheral edge sections of the oblong holes 10, 20 of the L-shaped metal fittings 1, 2. Lug portions may be formed in turn, or the inner peripheral faces may be formed with circular arc portions only, or the lugs may be formed staggeringly by a half-pitch in turn on the opposite long site portions of the inner peripheral faces. The protruded shapes and protruded quantities of the lugs are set to proper shapes and lengths according to the outer diameter sizes of screws to be used and the material and strength of the L-shaped metals fittings 1, 2. When external force such as shock force or sporadic force is applied, the occurrence of a shift or a play can be prevented. No looseness or no deflection is generated by an earthquake and the use over a long period, and reliability can be increased.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a unit bus,
The present invention relates to an L-shaped metal fitting for fixing between a unit main body such as a shower unit and a toilet unit and a building frame for accommodating the unit main body to prevent the unit main body from shaking or bending.

[0002]

2. Description of the Related Art When a unit bath is attached to a bathroom part inside a building, for example, as shown in FIG.
For example, the unit bus body 102 is attached using an L-shaped bracket 101 or wood.

In addition, such L-shaped fittings have been developed and used in which a screw hole for fixing is formed in a long hole shape in consideration of usability, adjustment of a distance between a building and a unit bath, and the like. .

[0004]

However, in such an L-shaped fitting with a long hole, the screw to be tightened may move along the longitudinal direction of the long hole and be displaced, resulting in loosening or rattling.

[0005] In the case of fixing using wood or the like, cracks and tears are generated due to its properties, and the fixing tool is not reliable.

In view of the above circumstances, it is an object of the present invention to provide a highly reliable L-shaped bracket which does not loosen or bend for a long period of time.

[0007]

That is, according to the first aspect of the present invention, an elongated hole for fixing with a screw is formed, and the unit main body portion such as a unit bath, a shower unit, a toilet unit, and the like are provided. What is claimed is: 1. An L-shaped metal fitting for fixing between a building body part for housing a main body part and shaking and bending of a unit main body part, wherein a convex portion is provided on an inner peripheral surface side of said long hole, and a building or unit main body is provided. Even if an external force such as an impact force or a sudden force acts on the motor, the external force is prevented from causing a shift or rattling.

In the invention according to a second aspect, the protruding portions are formed at opposing positions on the opposing long sides of the inner peripheral surface of the long hole.

According to a third aspect of the present invention, the convex portion is formed at a position shifted by a half pitch from a facing position facing each other on each of the long sides of the inner peripheral surface of the long hole facing each other. .

[0010]

Embodiments of the present invention will be described below with reference to the accompanying drawings. FIG. 1 shows a state in which a bath unit (flange portion 4A) 4 is attached to a bathroom frame 3 using L-shaped fittings 1 and 2 according to the present invention. , FIGS. 2 and 3
As shown in the figure, a plurality of projections (projections) 10A, 20A are formed at the inner periphery of the elongated holes 10, 20 at a constant pitch.

As a specific embodiment of the projections formed in the elongated holes 10 (20), the projections 10A (20A) may be formed at a constant pitch L as shown in FIG. That is, in the one shown in FIG.
Straight portions and protrusions (formed of arcs) are formed alternately. Further, as shown in FIG. 5, the elongated hole 10 (20) may have an inner peripheral surface formed only by an arc portion without forming a straight line portion. In this case,
A plurality of circular objects are formed so as to partially overlap each other so that the distance between the centers is S.

According to the present invention, in addition to the above-described embodiment, as shown in FIG. 6, for example, an L-shaped fitting is provided on each of the opposing long sides of the inner peripheral surface of the long hole 50 with a half pitch shift. 50B may be alternately formed.

The shape and amount of projection of the projection of the present invention are not particularly limited, and the outer diameter of the screw or the like to be used or L
An appropriate shape and length can be applied according to the material and strength of the metal fittings. In this embodiment, two pairs of L
Although a metal fitting was used, it may be attached with only one.

In these embodiments, the present invention is applied to a bath unit used in a bathroom. However, the present invention is not limited to this. For example, a shower unit, a toilet unit, and other means for fixing between appropriate members It can be applied in various fields.

[0015]

As described above, according to the present invention, a long hole for guiding a fixing screw is provided, and a convex portion protruding inward by a predetermined length from the inner peripheral surface of the long hole. The structure is designed to prevent the occurrence of displacement or rattling even if external force such as impact force or sudden force acts on the building frame or the unit body. , Etc., can be provided with high reliability without causing loosening or bending.
