Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an assembly type interior bar that matches interior decoration and is used as a handrail, towel rack, etc.

[Prior art and its problems]

Interior bars that are generally installed and used indoors, including living rooms, bathrooms, toilets, and washrooms, are made of so-called metals such as aluminum, brass, and stainless steel, and they give a cold feel that is unique to metal, making them uncomfortable to use.

Further, since this type of metal interior bar is formed to a fixed size, there is a problem in that even if the user wants to change the length arbitrarily depending on the user's convenience, it is impossible to respond to the request.

[Technical issues]

The technical problem of the present invention is to provide a connecting structure whose length can be freely changed while integrally forming the outer skin with a material that is warm when used and can be applied with a wide variety of color repertoires.

[Means for solving technical problems]

The means for achieving the above technical problem is to form integrally a plastic covering material longer than the metal tube on the outer surface of a metal tube to which a bush having threaded holes at both ends is fixed, so that the end surface of the bush and the plastic coating are integrally formed. Forming the required number of handrail members having a fitting space between them and the end face of the covering material, one half of which is in the fitting space of the adjacent handrail member, and the other half of which is the fitting space of the adjacent handrail member. A pair of screw rods, which are screwed into the screw holes of the bushings, are protruded backwards from the fitting portions that fit into the fitting portions, respectively, to form a connecting fitting, and the fine screws are inserted into the screw holes of the adjacent handrail members, respectively. The handrail members are connected by screwing together so that the end surfaces of the plastic covering material abut each other, and a tightening space for fine adjustment is formed between the inner end of the fitting portion of each connecting fitting and the bushing side end.

〔Example〕

Next, embodiments of the present invention will be described based on the drawings.

The assembled interior bar of the present invention consists of necessary handrail members A and connecting fittings B for connecting them.

Handrail member A is formed by integrally forming plastic coating material A ₃ on the outer surface of metal tube A ₂ with bushes A ₁ fitted and fixed at both ends. The handrail member A is formed into a desired shape such as a U-shape, a U-shape, a T-shape, etc., and is fixed to a mounting wall surface C. A mounting flange 2 is formed protruding from an end face thereof.

Metal tube _a2 is formed using steel or other desired metal material.

The bush _a1 has a screw hole _a1-1 for a fine screw _b3 , and is fitted and fixed to both ends of the metal tube _a2 so that the screw hole _a1-1 faces toward the opening direction.

The plastic covering material _a3 is made of thermoplastic material such as nylon or ABS resin, and is made to reveal various colors depending on the color pigment added, and is formed to be slightly longer than the metal tube ₂₂ . , is integrally formed on the outer periphery of the metal tube _A2 to form a fitting space _A4 between the end face of the bushing _A1 and the end face of the plastic covering material _A3 .

The connecting fitting B has a fine thread b 2 in the fitting part b ₁ that fits into the fitting spaces a ₄ and a ₄ of the adjacent handrail members A and A, respectively _.
The thickness of the fitting part _{b 1 is} determined by the length of the cavity formed by the pair of fitting spaces a ₄ and a ₄ of the adjacent handrail members A and A. The thickness of the thin screws _{b 2} , b ₂ is also slightly reduced as shown in Figure 2.
adjacent handrail member A, A screw hole a ₁ -1, a ₁
-1, a tightening space 1 for fine adjustment is formed between the inner end of the fitting part _b1 and the side end of the bush _a1 .

The tightening space 1 for fine adjustment and the fine screw _b2 function to freely adjust the assembly angle of the handrail member A.
In detail, first, plastic covering material is applied to the screw holes _a1-1 and _a1-1 of both adjacent handrail members A and A.
Adjacent handrail members A, A are connected by screwing together until the end faces of a ₃ and a ₃ abut against each other. In this state, when one or both of the handrail members A is further forcibly rotated, the plastic covering materials a ₃ and a ₃ will shrink slightly due to the elasticity of the material with their end surfaces still in contact with each other, causing the fine screws to tighten. By the function _b2 , the tightening space 1 for fine adjustment is rotated until it deteriorates, and the assembly angle can be adjusted freely (Fig. 2).

Figures 4 to 7 show handrail members A of various shapes.
An example of an assembly type interior bar assembled and formed using the following is shown.

By the way, a prefabricated interior bar can be constructed by connecting all the handrail members A of the same color, but it is also possible to change the color of every other handrail member A, or to make one half of the bar a different color from the other half. , the pattern is not particularly limited. The flange 2, which is fixed to the mounting wall surface C by screws 3, is fitted into a cushion material 4 having a locking protrusion 4' on its outer circumferential surface, and is covered with an inner circumferential surface that engages with the locking protrusion 4'. It is covered with a flange cap 5 having a locking protrusion 5' around it.

[Function and effect of the idea]

As described above, the present invention is based on the outer surface of a metal tube to which a bush having screw holes for fine screws is fixed at both ends.
A plastic sheathing material that is longer than the metal tube is integrally formed to form the required handrail member having a fitting space between the end face of the bush and the end face of the plastic sheathing material, and a handrail member that is necessary for a pair of adjacent hands. A pair of fine screws to be screwed into the screw holes of the bushing are protruded backwards from each other in a fitting portion that fits across the fitting space of each of the rubbing members to form a connecting fitting, and the fine screws are adjacent to each other. The handrail members are connected by screwing them into the screw holes of the handrail members, with the end surfaces of the plastic sheathing materials in contact with each other, and the tightening for fine adjustment is applied between the inner end of the fitting part of each connection fitting and the bushing side end. Since the space has been formed, when the assembling interior bar is formed by screwing the fine screws of the connecting fittings into the screw holes of the adjacent handrail members and bringing the ends of the plastic covering materials into contact with each other, the assembling interior bar is When the handrail members with irregular shapes such as 45° elbow shape, 90° elbow shape, T-shape, etc. are forcibly rotated, the end surfaces of the plastic sheathing material remain in contact with each other due to the elasticity of the material. While contracting, the handrail member rotates while maintaining a constant connection force due to the function of the fine screw until there is no more tightening space for fine adjustment, and it is also possible to stand still at any angle.

Therefore, it is possible to quickly adapt to the special case where the mounting wall surfaces are not on the same plane, such as when one mounting wall surface is orthogonal to the other mounting wall surface.

Furthermore, by manufacturing the same type of common connecting fittings in addition to the handrail members, it is possible to construct an assembly-type interior bar whose length can be freely changed, so the number of parts can be minimized and parts management can be greatly simplified.

In addition, plastic covering material is used as the skin of the handrails that make up the prefabricated interior bar, which eliminates the cold feel of metal and gives it warmth, and allows for a wide variety of color repertoires, making it ideal for users. Able to respond to requests.

Thus, the intended purpose can be achieved.
