Description

[Detailed explanation of the idea] [Industrial application field]

This invention relates to an improvement of a hook member for displaying products.

[Conventional technology]

2. Description of the Related Art Hitherto, various configurations of hook members have been known that are attached to a surface such as a wall, either singly or in a scattered manner, for suspending products or the like. However, those configured to hang products individually have a complicated structure, and those arranged in a scattered manner have the disadvantage that the mounting position is fixed like a hanger board. In addition, in the hanger mounting structure of Utility Model Publication No. 17186,
A cylindrical bushing is fitted and engaged with the cylindrical object to be attached, and a rod-shaped hook portion with a tapered outer diameter at the front end is fitted into the bushing, and the tip side is connected to the taper of the bushing. A structure is disclosed in which the bushing is pressed with a shaped part and the collar of the bushing is pressed against the circular hole with an elastic structure. However, in the above configuration, the cylindrical bushing is engaged with and attached to the object to be attached, and the rod-shaped hook is inserted therein for connection, so there are three components, and the hook is the tapered part of the bush. It has the disadvantage that it needs to be inserted beyond the holder and cannot be installed if there is no space in the depth direction, and since the bushing is flexible, it is difficult to hold it when a strong load is applied to the hanging part. There is a drawback that the hanging part is unstable.

[Problem that the invention attempts to solve]

This idea was devised as a result of intensive research in view of the above circumstances, and its main problem was to fix the hook base to the wall surface, and to fix the hook base so that the fitting shaft abuts the inside of the hook base. To provide a hook member which can be connected to disperse the load applied to a fitting shaft, and which can engage or screw the fitting shaft within the hook base so that there is no need to provide a space in the depth direction beyond the hook base. be.

[Means to solve the problem]

In order to solve the above-mentioned problems, this invention (a) provides a hook base which is made of a cylinder with a bottom and has a hollow part that is open at one end, and whose bottom wall surface is fixed to the mounting surface; (b) (c) a columnar base having a hook means at its tip; (c) a columnar base having a hook means at its tip; ,
a fitting shaft extending toward the proximal end along the axis of the base portion and fitting with the inner surface of the circumferential wall of the hook base without a gap; and a fitting shaft having a large diameter concentric with the fitting shaft with a gap therebetween (d) a hook shaft portion having a cylindrical cover portion extending in the direction of extension of the outer circumference of the hook base and covering the entire length of the outer peripheral wall of the hook base; A technical measure is taken to provide a convex hooking component or threaded portion that can be expanded and contracted by elasticity on the hook shaft side that engages or screws with a concave hooking component or threaded portion on the hook base side. ing.

[Effect]

A hook base is fixed to a mounting surface, and a hook shaft portion is fitted into a hollow portion of the hook base from the outside. A convex latching structure or threaded portion formed on the fitting shaft of the hook shaft and capable of expanding and contracting due to elasticity, and a concave latching structure or threaded portion formed on the inner surface of the peripheral wall of the hook base. Latch or screw together to connect the two only within the hollow (without protruding outward). Thereby, the fitting shaft fits into the peripheral wall of the hook base without any gap, so that the load applied to the fitting shaft can be dispersed. In addition, since the cover part covers the peripheral wall of the hook base, the inside of the hook base is sealed and the fitting shaft is protected, and there is no unevenness in the overlapped portion with the hook base, making it safe.

【Example】

Preferred embodiments of the hook member according to this invention will be described below with reference to the drawings. A hook member 1 shown in FIGS. 1 and 2 is composed of a hollow hook base 2 and a hook shaft portion 3 connected to the hook base 2. As shown in FIGS. That is, in this embodiment, the hook base 2 has a hollow cylindrical shape with an open end, and the mounting screw is inserted into the installation wall surface 21 which is the bottom surface of the hook base 2 and abuts the mounting surface W. A screw hole 22 for use is transparently provided. A hooking component 4 is formed on the inner wall of the hollow portion of the hook base 2 on the proximal end side. In the case of this embodiment, the hooking component 4 is formed by an expanding groove 4 which is depressed in a step-like manner and then sloped to become shallower gradually.
1 is formed into a ring shape. This hook base 2 is screwed to the mounting surface W at three locations in this embodiment through the screw holes 22 by mounting screws V, and in the direction perpendicular to the mounting surface W, in the illustrated example. It is installed almost horizontally. Next, the hook shaft part 3 that fits into the hook base 2 has a cylindrical cover part 6 whose insertion side is open on its base end side (the side where the hook base 2 is fitted), and a cover part 6 of the cover part 6. It has a fitting shaft 7 that is provided in a hollow interior and protrudes concentrically with a small diameter with a gap in the circumferential direction. Here, the fitting shaft 7 has a cylindrical shape,
On the insertion end side, when the hook shaft portion 3 is inserted into the hook base 2, there is a pair of the hook structure portion 4 of the hook base 2 at a location that aligns with the above-mentioned hook structure portion 4 (expansion groove 41). A hook component 5 on the hook shaft side that can be freely engaged and detached is formed. In this embodiment, the hook component 5 on the hook shaft side is formed by an annular groove 51 bored in the outer periphery of the fitting shaft 7.
and an elastic ring 52 externally fitted into the annular groove 51. In this embodiment, the elastic ring 52 is
Although a portion thereof is separated, it may be an annular body made of an elastic material such as rubber or a coil spring, and is configured to contract or expand in the radial direction of the annular groove 41. The base end side of the fitting shaft 7 is integrally connected to a base portion 30 having a hook means F. In the illustrated example, a threaded surface is formed on the inner wall on the proximal end side of the cylinder constituting the cover part 6, and the hook-like hook means F is screwed into the outer periphery of the base 30 that protrudes in the extension direction. It consists of a structure in which a threaded surface is formed and the two are assembled by screwing together. In addition to the above-described configuration, the hook shaft portion 3 has a base portion 30 having a disk-shaped flange extending in a concentric large diameter shape orthogonal to the cover portion 6, as shown in FIG. 3, for example.
It is also possible to have A fixedly installed. With the above configuration, in order to connect the hook shaft portion 3 to the hook base 2 fixed to the mounting surface W,
When the fitting shaft 7 of the hook shaft 3 is fitted and inserted into the hollow of the hook base 2, the latching structure 5 of the hook shaft 3 is latched to the latching structure 4 of the hook base 2. That is, the elastic ring 52 of the fitting shaft 7 is urged and pressed in the direction of expansion by the inner circumferential wall of the hook base 2 into which it is inserted, and is elastically deformed in the direction of contraction. When the elastic ring 52 comes to the expanded groove 41 of the hook base 2, the annular ring 42 is expanded by the biasing force and is latched and aligned within the expanded groove 41. On the other hand, when pulling out, if a strong force is applied in the pulling direction, the pieces can be separated in the reverse direction. Here, it is preferable that the tip of the fitting shaft 7 is formed into a guide surface G that gradually narrows in width so that it can be easily inserted into the hollow of the hook base 2. In this invention, the hook means provided on the hook shaft portion 3 has, in addition to the above-mentioned configuration, a hook member as a stay, and a pair of hook members as the stay are provided in the left and right direction, and a display shelf is provided on the tip side of the stay. It may also be configured to support it. In addition, a hook structure used for product display and other holding structures may be added to the hook shaft portion 3 as appropriate.In short, the structure of the hook shaft portion of the present invention is limited to the structure for connection with the hook base. only. Therefore, the hooking component of the hook shaft portion is shared, and appropriate hook elements (structure for hanging products, etc., structure for hanging hanging tools such as hangers, etc.) are used.
It is sufficient to prepare a large number of hook shaft portions with additional features, and to attach the hook shaft portion selected according to the application to the hook base. Furthermore, it is preferable to attach a plurality of hooks to appropriate locations on the hook base, since the desired locations can be used depending on the purpose. In this invention, instead of the hooking components provided on the hook base and the hook shaft, a pair of threaded parts 4' and 5' which can be screwed together as shown in FIG. It can produce effects. Note that the other configurations are the same as those of the previous embodiment, so the same configurations are given the same reference numerals and the explanation thereof will be omitted.

[Effect of the idea]

This hook member can be expanded and contracted by connecting the hook base and the hook shaft with a concave latching component formed halfway toward the proximal end of the inner surface of the circumferential wall of the hook base, and elasticity formed on the outer periphery of the fitting shaft. Since the connection is made by engaging in combination with a convex-shaped hook component or by screwing, there is no need for the fitting shaft to protrude outward from the hook base, and the hook base can be shaped into a cylinder with a bottom. It can be fixed to a surface to be mounted such as a wall. Furthermore, since the cover portion covers the entire peripheral wall of the hook base, the inside of the hollow portion of the hook base can be sealed, and rusting and deterioration of the fitting shaft can be prevented. Furthermore, since the fitting shaft fits into the peripheral wall of the hook base without any gaps, the two abut against each other over a wide area, and the load applied to the fitting shaft can be dispersed to the hook base, increasing the strength of article retention. can. This is extremely beneficial as it allows the hook member to be made smaller and lighter.
