Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an L-shaped metal fitting that prevents a unit main body portion from shaking and bending by fixing between a unit main body portion such as a unit bath, a shower unit, and a toilet unit and a building housing portion that stores the unit main body portion. It is.
[0002]
[Prior art]
When a unit bath is attached to a bathroom part inside a building, for example, as shown in FIG. 7, an appropriate fitting such as an L-shaped fitting 101 or wood is attached to the wall or ceiling (building part) 100 of the installation part. The unit bus main body 102 is attached by use.
[0003]
In addition, such L-shaped metal fittings have been developed and used in which a screw hole to be fastened is formed in a long hole shape in consideration of ease of use and adjustment of the distance between the building and the unit bath.
[0004]
[Problems to be solved]
However, in such an L-shaped metal fitting with a long hole, a screw to be tightened may move and shift along the longitudinal direction of the long hole, resulting in looseness or rattling.
[0005]
In addition, when fixing using wood or the like, due to its nature, cracks and tears are generated, and it is not reliable as a fixture.
[0006]
In view of the above circumstances, an object of the present invention is to provide a highly reliable L-shaped metal fitting that does not loosen or bend over a long period of time.
[Means for Solving the Problems]
To achieve the above object, the present invention is a long hole is bored for guiding the fixing screws, bathroom, building structures for accommodating shower unit, the units body portion and the unit main body portion such as a toilet unit An L-shaped bracket that fixes the gap between the parts and prevents shaking and bending of the unit body part. The two long holes of the L-shaped brackets are partially overlapped, and a screw is inserted into the overlapped elongated hole. In the L-shaped metal fitting used for fixing, a plurality of protrusions are formed on the opposing long sides of the inner peripheral edge of the long hole so as to protrude inward at opposite positions facing each other at a constant pitch interval L, When a straight line portion D is formed between these protrusions 10A or between the protrusions 20A or arc portions are formed, and the arc portions and the protrusions are alternately formed, the distance between the centers of a plurality of circular objects is S. As one It is formed by overlapping parts .
[0008]
DETAILED DESCRIPTION OF THE INVENTION
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 housing part 3 using L-shaped brackets 1 and 2 according to the present invention. as shown in FIGS. 2 and 3, the inner peripheral edge portion facing the long sides to the collision force 10 a of the long holes 10, 20, 20A are formed in plural at a constant pitch L.
[0009]
As a specific aspect of the protrusion formed in the long hole 10 (20), for example, the protrusion 10A (20A) may be formed at a constant pitch interval L as shown in FIG. That is, in the structure shown in FIG. 4, straight portions D and protrusions ( consisting of two arcs) are alternately formed on the inner peripheral edge of the long hole 10. Further, as shown in FIG. 5, the long hole 10 (20) may have a configuration having an inner peripheral surface formed only by an arc portion without forming the straight portion D. In this case, a plurality of circular objects are partially overlapped so that the distance between the centers is S.
[0010]
Further, in the present invention, in addition to the previous embodiment, as shown in FIG. 6, for example, as shown in FIG. It may be formed.
[0011]
In addition, the protrusion shape and the protrusion amount of the protrusion of the present invention are not particularly limited, and those having an appropriate shape and length according to the outer diameter dimension of the screw to be used and the material and strength of the L-shaped metal fitting are applied. I can .
[0012]
In these embodiments, the present invention is applied to a bath unit used for a bathroom part, but of course not limited to this. For example, various kinds of means for fixing between a shower unit, a toilet unit, and other appropriate members can be used. Application in the field is possible.
[0013]
【The invention's effect】
As described above, according to the present invention, a long hole for guiding a fixing screw is provided, and a protrusion protruding inward by a predetermined length is provided on the inner peripheral surface side of the long hole, so that the building frame Even if external force such as impact force or sudden force acts on the part or unit body, it is configured to prevent deviation and rattling from occurring due to these external forces. It is possible to provide a highly reliable product that does not cause looseness or deflection.
