Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a base of a hanging device, and relates to a base of a hanging material for hanging objects such as clothes hangers, products, and support stands for displayed products.

[Conventional technology]

Japanese Utility Model Publication No. 51-22497 discloses a mounting bracket in which the flat parts of two metal rods with a semicircular cross section are brought into close contact, a threaded part is provided on the outer periphery of each front part, and each rear part has a vertical part bent in the upper and lower directions opposite to each other. A mounting bracket for decorative plywood is described in which a bush is fitted into a mounting hole formed in the plywood, each outer peripheral part of which fits into the mounting hole, and a nut is screwed into the threaded part. The above method has a structure in which the flat parts of two semicircular metal rods are brought into close contact with each other, and there are also two vertical parts that engage with the back side of the mounting hole of the decorative plywood at 180° intervals, so there is a drawback that stability is not sufficient.

(Problems to be Solved by the Present Invention) Stability is most important for hanging devices for hanging objects such as clothes hangers, products, and display product support stands. In view of the fact that the two-piece mounting bracket described in the above-mentioned publication is unstable, the present invention attempts to solve the problem by improving stability by forming it with three pieces, and the purpose of the present invention is to solve this problem. It is.

(Means for Solving the Problems) The object of the hanging device base of the present invention is to specifically solve the problems mentioned in the previous section. Three pieces 1, 1, which are cut into three parts.
1 each is provided with a joint surface 2, 2 that allows three pieces to be assembled in a circular rod shape, and an outer peripheral surface 3, 3, 3 with an arcuate cross section that constitutes the outer periphery when the circular rod shape is assembled,
Engagement protrusions 4, 4, 4 are provided at each end of the outer circumferential surfaces 3, 3, 3 and protrude substantially perpendicularly to the outer circumferential surface side, and each outer circumferential surface 3, 3, 3 is tightened by a cylindrical assembly. A female thread 5 is formed to screw the nut 12, and the engagement projections 4, 4, 4 of each piece 1, 1, 1 are connected to a panel, etc.
It passes through the through hole 22 formed in the panel, etc. and engages with the back surface of the panel, etc. 21, and the engaging projections 4, 4, 4 are inserted into the female threads 5 of the individual pieces 1, 1, 1 assembled in a circular rod shape. 21 and a tightening nut 23 is screwed together, which facilitates installation and increases the installation strength of the hanging material.

A preferred embodiment of the invention is described in the following section.

(Example) Fig. 1 shows the elemental pieces 1, 1, 1 of the present invention, and each elemental piece 1 can be assembled into three pieces to form a cylindrical assembly shown in Figs. 2 and 3. ° angle joint surfaces 2, 2;
When assembled, an arcuate outer circumferential surface 3 constituting the cylindrical outer surface 6 is formed, and an engaging protrusion 4 protruding toward the outer circumferential surface 3 at a substantially right angle to the end of the outer circumferential surface 3 is formed. A male thread 5 of approximately 1/3 size is formed by rolling or the like on the entire outer circumferential surface of each piece 1 in front of the engagement protrusion 4 or on a part connected to the engagement protrusion 4.
The outer circumferential surfaces 3 do not need to be in close contact with each other, but may be chamfered to form a groove on the outer surface of the boundary in the axial direction between adjacent ones.

In this embodiment, a through hole 22 with a slightly large diameter is bored in the panel 21 etc. as shown by the chain line in FIG.
1 and 1 are taken apart and tilted one by one with respect to the axis of the through hole 22 so that the engaging protrusion 4 protrudes from the back side of the through hole 22, and after all three have been passed through, the joining surfaces 2 are brought into close contact with each other and pulled. Align them, pull them out of the through hole 22, and hook each engaging protrusion 4 to the hole edge on the back side of the through hole 22 as shown in Figs. 3 and 4, thereby forming a circular rod-shaped outer periphery 6. , the female threads 5 on the outer circumferential surfaces 3 of each piece 1, 1, 1 are continuous or interrupted, a washer 11 is fitted, a tightening nut 12 is screwed in, and the washer 11 is attached to the panel 21 etc. as shown in the figure. Make strong contact as indicated.

The through hole 22 is closed by a washer 11.

As described above, panel 2 of the base of the hanging device of the present invention
This completes the assembly to the first unit, and screws a cap nut or other arbitrary shape hanging material 13 in front of the tightening screw 12 to hang daily necessities such as picture frames, neckties, clothes, or hangers. Or use it for business purposes by hanging products, business supplies such as product display stands. The aforementioned hanging material 13 can be formed integrally with the tightening nut 12.

(Operations and Effects) The structure and direction of use of the base of the hanging device of the present invention are clear from the description of the above embodiments, and the three pieces 1, 1, 1 have a circular rod shape including a round pipe shape. The shape is cut into three parts in the axial direction from the center, and an engaging protrusion 4 is formed at each end of each piece 1, 1, 1 to prevent engagement with the edge of the through hole 22 at 120 degrees. Since they are arranged at angular intervals, the above-mentioned engaging protrusions only touch the longitudinal center of the outer circumferential surface 3 in a linear manner, but since they make contact at three locations at 120° intervals, they are compatible with tightening by the tightening nut 12. Overall, the stability of each material is the conventionally known 2
The cross section of the semicircular bar could be significantly improved over that of the metal bar.
