Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hook used by hanging or hanging on a rod or the like and having a fixed function.

[0002]

2. Description of the Related Art For example, hangers and other clothes-drying equipment are provided with hooks for the purpose of suspending or hanging them. Such hooks are formed from an arc having a diameter larger than the outer diameter of a rod usually used. It has a bent portion consisting of. The hook is a slippery member for a rod or the like, and is effective when fixing is required, for example, Japanese Utility Model Laid-Open No. 58-119388,
No. 62-23698 is proposed. However, these hooks have a structure in which a member for fixing is pressed against a rod or the like by a spring, which is complicated and has to worry about breakage, and is unlikely to be expected to be effective.

On the other hand, the hook of Japanese Utility Model Laid-Open No. 4-32689 has an inner diameter part slightly larger than the diameter of the clothesline, and two protruding pieces are formed on the inner side of the inner part to form two hooks. It has a structure in which the rod is pressed against the inner part of the semi-circular locking portion by the projecting piece, and it is considered that it is simple and some effects can be expected. However, if the inner diameter is slightly larger than the diameter of the rod, the structural margin is insufficient, and stress concentrates at one point, which may cause damage.
Since it is not possible to expect a sufficient fixing force with the protruding pieces at some locations, it is considered necessary to provide a considerably large size and a sturdy structure in order to obtain a sufficient fixing effect.

SUMMARY OF THE INVENTION The present invention has been made in view of the above points, and its object is to provide a hook used for a rod or the like that can be securely fixed to a mating member such as a rod. Is to provide. Another object of the present invention is to provide durability that is unlikely to be damaged even when it is repeatedly attached to and detached from a rod. Still another object of the present invention is to facilitate attachment / detachment to / from a rod.

[0005]

In order to solve the above-mentioned problems, the hook of the present invention has a projecting shape such that two hooks are provided on each of the front and rear sides of the main body so as to be able to contact both the front and rear sides of a mating member such as a rod. The support part is provided, and the projecting support part is provided in a ridge line shape capable of contacting the surface of the other member such as the rod over a required length, and the bent portion is repeatedly attached to and detached from the other member such as the rod. In order to withstand the load, it has a detour portion that separates from a mating member such as a rod, and is a spring means that obtains a biasing force necessary for fixing to the mating member.

[0006]

BEST MODE FOR CARRYING OUT THE INVENTION A hook used in a rod or the like according to the present invention has a main body having a bent portion for hanging or hanging. Question mark type? Corresponds to the form of some body of the bend. In relation to that bend,
This hook can be fixed to a mating member such as a rod. The mating member is a rod, a bar (lateral bar) having a cylindrical outer peripheral surface, a pole or other members or portions.

In order to be able to contact both the front and rear sides of the mating member such as a rod, two projecting support portions are provided on each of the front and rear sides of the main body. The front and rear correspond to the front and rear of the mating member, and the direction in which the rod can be swayed with the bent portion hung can be either the front or the rear. The term "projective" means that it is more protruding than other parts.

The projecting support portion is provided in the shape of a ridge so that it can contact the surface of a mating member such as a rod over a required length. In other words, the protrusion of the support is not a dot,
It is necessary to make it linear or dotted and to make contact with the surface of the rod or the like for a certain length, and by this contact for a certain length, the resistance force necessary for fixing is obtained. The projecting support part
It is desirable to provide it in the longitudinal direction of a mating member such as a rod. Providing a projecting support for the required length in the circumferential direction of the mating member does not necessarily result in a bad result, but a better result is obtained in the longitudinal direction. Therefore, basically, the projecting support portion has only to have a required length, and its direction and the like can be freely determined.

In the case where the projecting support portion is provided so as to be contactable over the required length in the longitudinal direction of the rod or the like,
The width of the projecting support portion can be formed wider than the width of the main body of the hook (the invention according to claim 2). As a result, the necessary fixing force can be obtained without the entire hook becoming large and rugged.

In the main body below the supporting portion, one having a free end is opened outward, and a guide portion for guiding a mating member such as a rod between the supporting portions can be formed between the other end of the main body. (Invention of Claim 3). As a result, a mating member such as a rod can be comfortably fitted between the strong supporting portions.

In the projecting support, the support may not be provided in a projecting form, but the main body may be formed in a side shape such as a substantially W shape and a substantially C shape as a whole (the invention of claim 4). ). Are these side shapes traditional simple question mark shapes? Compared with, the shape is sufficiently unique, and the characteristic of the shape expresses the function of fixing in the present invention.

On the other hand, the bent portion has a detour portion which is separated from the rods in order to withstand a load (load) repeatedly applied to the mating member such as a rod or the like due to attachment / detachment. The bypass portion is largely separated from the outer peripheral surface of the rod to provide a structural allowance, relax stress concentration, and contribute to improvement of durability. Further, the bent portion serves as a spring means for obtaining a biasing force necessary for firmly fixing to the mating member. Although not only the bent portion is the spring means, but the entire hook is the spring means, the structure of the bent portion is a major factor in the design of the spring means.

It is preferable that the bent portion includes an arc having a radius smaller than an arc having a radius of the bent portion from the center of a mating member such as a rod fixed by the supporting portion (claim 5). Invention). This makes it possible to exhibit good spring characteristics while keeping the bent portion small. The hook used in the rod or the like of the present invention having such a configuration can have an appearance as a whole formed by bending a strip plate (the invention according to claim 6).

The hook used in the rod or the like according to the present invention can be manufactured as a plastic molded product, and accordingly, the size, the size, the color, the shape, etc. of the plastic can be varied. Further, it is possible to manufacture the same by processing a metal plate material, and in that case, the durability is further improved. Further, a composite structure of plastic and metal can be manufactured in the same manner, and both performance and durability are expected to be improved, but the manufacturing cost tends to increase.

The present invention will be described in more detail with reference to the embodiments shown in the drawings. FIG. 1 is an embodiment in which a hook 10 used for a rod or the like according to the present invention is applied to a so-called hanger H,
The hook 10 has a body 12 with a bend 11 for hanging and hanging.

The main body 12 is provided with projecting support portions 13, 14, 15, 16 at two locations on each of the front and rear sides so as to contact the front and rear sides of a mating member 20 such as a rod (see FIG. 2, see FIG. 3). Projecting support parts 13, 14, 15, 16
Has two locations each in front and back, for a total of four locations.

The illustrated main body 12 has a strip plate-like structure, and has projecting support portions 13, 14, 15, 16 on both front and rear sides of the bent portion 11 at positions facing each other. ing. The projecting support portions 13 to 16 are formed by providing a wider portion than the width of the main body 12 at the above-mentioned location of the main body 12 having a strip plate structure, and the main body has a short free end. The front side support portions 13 and 14 of 11 have a substantially W-shaped side surface shape, and the rear side support portions 15 and 16 have a substantially C-shaped side surface shape. The concave portion 17 is formed so as not to come into contact with the peripheral surface of the mating member 20 such as a rod. Further, since the front support portions 13 and 14 are W-shaped, they are also valleys and do not contact the mating member 20. This is because contact with the circumferential surface in a plane makes it rather slippery. The projecting support portions 13, 14, 15, 16 in the embodiment are ridge-shaped and are in contact with the mating member 20 for a required length in the longitudinal direction.

Further, front and rear supporting portions 13, 14, 15, 16
The W type and the C type increase the rigidity of the same portion, and enable firm fixation with the mating member 20 such as a rod. The biasing force for fixing is obtained by the spring means, and in the embodiment, the elasticity of the region including the support portions 13, 14, 15, 16 on both front and rear sides of the bent portion 11 as the center constitutes the spring means. is doing. The bent portion 11 is the support portion 1.
Mating member 20 such as a rod fixed to 3, 14, 15, 16
Of the main body 12 on the rear side of the upper portion of the main body 12, and an arc A1 having a radius R1 from the center O of the main body 12 to the curved portion 11 and an arc A2 having a smaller radius R2. In combination with a larger-diameter arc A3 that governs A, the asymmetric detour 21 that is closer to the front than the midpoint of the front and rear supports 13, 14, 15, 16 is formed (FIG. 2). The detour portion 21, together with the front and rear bent portions 11 and the projecting support portions 13, 14, 15, 16 constitute spring means.

In the body 12, the free end 1 below the support
The front end that is 8 is open outward (forward), and the other 19 of the main body 12 is a portion that has moved downward, so that the space between them is an inlet that is larger than the diameter of the mating member 20. . At the front end, the mating member 20 is supported by the supporting portions 13, 14, 1
While it serves as a guide for fitting to 5, 16, it also serves as a finger hook for opening the hook at the time of removal. As another finger rest corresponding to the finger rest (18), a protrusion 22 is provided on a crank portion 23 below the main body 12. A vertical portion 24 extending downward from the crank portion 23 is a connection portion with a hanger H or the like, and a vertical axis passing through the vertical portion 24 is a rod (20) fixed to the support portions 13, 14, 15, 16
It is set at a position near a perpendicular line passing through the center O of the or, or slightly outward (forward).

The substantially W-shaped supports 13, 14 and the substantially C-shaped supports 15, 16 and the bent portion 11 in the forwardly offset position give the hook body 12 a particularly distinctive lateral shape. There is. Further, the main body 12 has an outer shape that is formed by bending a strip plate as a whole, and the supporting portions 13, 14, 1
Combined with the wide widths of 5 and 16, it creates a very impressive design. The hook 10 shown in the embodiment having such a shape and structure is manufactured by plastic molding and constitutes a part independent of the hanger.
However, it is obvious that the present invention can be applied to a hook that is not independent of a hanger or the like and has an integral structure with it.

The hook 10 of the present invention thus constructed
When the hook is hooked on the mating member 20 such as a rod, the hook 10 is turned over the mating member 20 so that the hook is hooked on the mating member 20 from the guide portion (FIG. 4 top). Supporting member 1 for supporting member 20
When the hook 10 is operated to be pushed into 3, 14, 15, and 16, the entire hook 10 is spread forward and backward, so that the mating member 20 is inserted between the front and rear supports (in FIG. 4). When it is pushed further in, the mating member 20 causes the support parts 13, 14, 1
It will be in a fitted state so that it will fit between 5 and 16, and will be stable (Fig. 4 lower).

Thus, the front, rear, upper and lower four-point support (four-line support)
As a result, the hook 10 is fixed to the mating member 20, and becomes difficult to move in the circumferential direction and the longitudinal direction. Further, in the fixed state, the detour portion 21 having the curved portion 11 as the apex is separated from the mating member 20 by a considerable distance S, and the arcuate portion 41 above the upper support portions 13 and 15 has a high rigidity and a width of Since the diameter of the mating member 20 is smaller than that of the mating member 20, the mating member 20 such as a rod is securely fixed, and there is no possibility of moving to the inside (upward) of the arc-shaped portion 41. Regarding the structure during this period, the present invention is an extension of the invention idea of the previous application (2000-245120), the rigidity of the bypass portion 21 is high, and a certain amount of force is required for attachment / detachment to / from the mating member 20. .

When removing, the reverse operation is performed.
At that time, the free end 18 at the tip of the hook is opened outward,
Moreover, since the protrusion 22 is provided in the lower portion of the main body, it is easy to push and the operability is good. As described above, the hook 10 of the present invention has a structure in which stress when detaching from or attaching to the mating member 20 is distributively applied to the arc-shaped portion 41 in a distributed manner and is not concentrated, and the durability is improved.

[0024]

EFFECT OF THE INVENTION Since the present invention is constructed and operates as described above, the four linear support portions provided at two locations on each of the front and rear sides of the main body ensure reliable operation with respect to a mating member such as a rod. It can be firmly fixed, is not easily damaged even if it is repeatedly attached to and detached from the rod, can be attached and detached smoothly, and the features of the outer shape express the function, and other remarkable effects are exhibited.
