[0006]

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described with reference to the drawings.
Reference numeral 1 denotes an article such as a handrail attached to a wall surface 2, a grip bar, a towel rail, etc. The article 1 includes an article body 3 and a wall surface fitting 5 attached to an end portion of the article body 3 via an intervening expansion / contraction member 4 described later. It consists of. The structure of the wall surface mounting tool 5 is arbitrary, but as an example thereof, the mounting screw cylinder 8 is screwed and fixed to the fixed pedestal 7 fixed to the wall surface 2 with the screw 6.
Reference numeral 9 is a stepped screw for attaching the attachment screw cylinder 8 to the attachment body 10.

A fitting shaft portion 13 to be inserted into the opening 12 at the end portion of the article body 3 is formed on the wall surface fitting 5. The fitting shaft portion 13 has a thread groove 14 on the mounting tool side on the outer peripheral surface on the wall mounting tool 5 side.
Is formed, and the tip side of the attachment-side screw groove 14 is formed on the attachment-side cam portion 15 whose diameter becomes smaller toward the tip. On the fitting shaft portion 13 side of the interposing expansion / contraction member 4, a screw cylinder 18 having an expansion / contraction member side screw groove 17 is provided on the inner peripheral surface, and the tip side (the article body 3 side) of the screw cylinder 18 is formed in a cylindrical shape. A cut 19 in the direction of the mother ship is formed in the cylindrical member and divided into a plurality of pieces in the circumferential direction to integrally form a rotating piece 20 having a free end. Rotating piece 2
A retaining engagement projection 21 is formed on the outer peripheral surface of the groove 0.

An anti-slip member 22 is provided on the outer periphery of the tip of each rotating piece 20.
The engaging groove 23 for engaging with is formed. The non-slip member 22
Is to prevent the intervening expansion / contraction member 4 from rotating by coming into contact with the inner peripheral surface of the article main body 3, which is called an O-ring by those skilled in the art, such as heat resistance, chemical resistance, and wear resistance. Although it may be made of a synthetic resin such as high synthetic rubber, it is preferable to use a synthetic resin having a large contact friction resistance and elasticity.

Therefore, the inner peripheral surface of the rotating piece 20 is an inner cam surface that rotates each rotating piece 20 outward when the outer peripheral surface of the fitting-side cam portion 15 of the fitting shaft portion 13 comes into contact. The inner cam surface 24 is formed so as to project inward as it reaches the tip.

[0011]

Next, the operation will be described. Fitting shaft part 1 of wall mount 5
The expansion / contraction member side screw groove 17 of the interposing expansion / contraction member 4 is screwed into the attachment tool side screw groove 14 of FIG. When the fitting shaft portion 13 and the intervening expansion / contraction member 4 are relatively rotated, the fitting-side screw groove 14 and the expansion / contraction member-side screw groove 17 mesh with each other and move in the axial direction. When the cam portion 15 and the inner cam surface 24 of the turning piece 20 come into contact with each other and further rotated, the attachment-side cam portion 15 widens the tip end of each turning piece 20 in the radial direction.

In this case, when the wall mount 5 is rotated,
Since the interposed expansion / contraction member 4 expands in the radial direction, the number of parts can be reduced. Further, the intervening expansion / contraction member 4 can be mounted by screwing the expansion / contraction member side screw groove 17 into the mounting tool side screw groove 14 of the fitting shaft portion 13 of the wall surface mounting tool 5, thus reducing the number of parts. At the same time, the mounting (assembly) is facilitated.

Therefore, the outer diameter of the anti-slip member 22 fitted in the engaging groove 23 at the tip of each turning piece 20 by moving the fitting-side cam portion 15 in and out of the inner cam surface 24 is set to the opening of the article body 3. The intermediary expansion / contraction member 4 is inserted and fitted in the article body 3 in this state so as to be substantially the same as the inner diameter of the portion 12. At this time, the anti-slip member 22 elastically deforms and passes when passing through the opening 12 of the article body 3, but the anti-slip member 22 adheres to the inner peripheral surface of the article body 3, so The article body 3 is fixed in the rotational direction.

In this state, when the wall mount 5 is rotated, the mount-side cam portion 15 of the fitting shaft portion 13 is screwed into the interposing expansion / contraction member 4, and the mount-side cam portion 15 rotates as described above. Each rotating piece 20 is brought into contact with the inner cam surface 24 of the moving piece 20.
The outer diameter of the anti-slip member 22 is increased by expanding the tip of the anti-slip member 22 to the outside.
Therefore, the article main body 3 is prevented from rotating or coming off in the axial direction with respect to the intervening expansion / contraction member 4, and is fixed to the wall surface mounting tool 5 via the interposition expansion / contraction member 4.

In this case, an engaging groove 23 for engaging the anti-slip member 22 is formed on the outer periphery of the tip of each turning piece 20, and the ring-shaped anti-slip member 22 is mounted in the engaging groove 23. ,
Easy to assemble. In addition, those having a large contact friction coefficient, such as what those skilled in the art call O-rings, have heat resistance, chemical resistance,
Since a synthetic resin having elasticity such as a synthetic rubber having high wear resistance is used, the durability is high and the anti-slip member 22 is provided even when the rotary piece 20 is rotated and expanded.
Grows and follows this, and works in all situations.

When the fitting shaft portion 13 is rotated, the wall mounting fixture 5 approaches the end portion of the article main body 3, so that the predetermined distance between the end surface 28 and the article body 3 is enough to rotate the fitting shaft portion 13. When the intervening expansion / contraction member 4 is first inserted and attached to the article body 3 so as to be opened between them, the attachment is completed as shown in FIG. 5, but the orientations of the wall attachments 5 attached to both ends of the article body 3 do not match. Then, it is necessary to rotate the fitting shaft portion 13 so as to return it, and a gap is formed between the end surface 28 of the wall surface fitting 5 and the end portion of the article body 3.

Therefore, the elastic member 27 is fitted to the fitting shaft portion 13 of the wall surface fitting 5, and the interposing expansion / contraction member 4 is then inserted as described above.
When the article main body 3 is attached with the interposition of, the gap between the end surface 28 of the wall surface fitting 5 and the end portion of the article main body 3 is elastic member 27.
Fills in and does not spoil the appearance. Further, depending on the initial insertion position of the intervening expansion / contraction member 4, a gap is formed between the end surface 28 of the wall surface fitting 5 and the end of the article body 3, but this is also filled with the elastic member 27, so a high degree of assembly accuracy is required. And make the work easier.

The order of assembling the wall mount 5, the article main body 3 and the interposing expansion / contraction member 4 is not limited to the embodiment and is not a requirement of the present application. Thus, in FIG. 5, the intervening expansion / contraction member 4
The outer diameter of the screw cylinder 18 is substantially matched with the inner diameter of the article body 3, but as shown in FIG. 7, the outer diameter of the screw cylinder 18 of the interposing expansion / contraction member 4 does not match the inner diameter of the article body 3. However, since the rotating piece 20 rotates outward to increase the diameter of the anti-slip member 22, the manufacturing error at this point is also absorbed, and the assembly becomes possible.

Assuming that the inner diameter of the article body 3 in FIG. 7 is a principle, the wall thickness of the metal tube 25 is increased so that the outer diameter of the screw tube 18 of the interposing expansion / contraction member 4 matches the inner diameter of the article body 3, It is also possible to improve the strength of the article body 3. Since the opening 12 of the article body 3 does not require any special processing including the inner circumference and the outer circumference, the article body 3 can be easily manufactured, and several kinds of article bodies 3 having different lengths can be manufactured. It is also not necessary to prepare, and it is also possible to set the optimum length at the installation site of the article body 3,
Improves transportation / workability and contributes to cost reduction.

Then, the fixture body 10 of the wall fixture 5
The mounting screw cylinder 8 is rotatably mounted by means of a stepped screw 9, and the screw groove on the outer periphery of the fixed pedestal 7 is screwed into the screw groove of the mounting screw cylinder 8 to complete the whole assembly. This assembly sequence is not a requirement. Then, the fixed pedestal 7 is brought into contact with the wall surface 2 on which the article main body 3 is mounted at a desired interval and fixed by the screw 6, and the screw groove of the mounting screw cylinder 8 is screwed into the screw groove on the outer periphery of the fixed pedestal 7. Then, the fixture body 10 and the fixed pedestal 7 are fixed, and the attachment of the article body 3 is completed.

In this case, as described above, the article main body 3 is immovable with respect to the interposing expansion / contraction member 4 by preventing rotation and slipping out in the axial direction. It becomes easy to fix to the fixed pedestal 7 fixed to the wall surface 2, and the working efficiency is improved.
