Description

[Detailed description of the invention] [Purpose of the invention] (Field of industrial application) The invention is a general-purpose clip that can be used as clothespins, pants hangers, clips used in laundry shops, and other clips. The present invention relates to a connecting device for metal hooks used in flexible synthetic resin clamping members, synthetic resin hangers, and the like.

(Prior Art) Conventionally, in most of the operating bodies of synthetic resin clamps, synthetic resin hangers, etc., the hook portions thereof were integrally made of a synthetic resin material.
(For example,
61-27080).

(Problem to be solved by the invention) However, when the actuating body of a synthetic resin clamping tool or the hook part of a synthetic resin hanger is integrally made of a synthetic resin material, the strength and durability of the hook part itself
In order to improve these characteristics, it is necessary to make the hook part itself thicker or to provide many reinforcing ribs on the hook part. It is difficult to manufacture the parts, and the hook part as a whole becomes large and bulky, resulting in high manufacturing costs. Particularly, when a hook portion is provided on the actuating body of the clamping tool, there is a problem in that it is extremely difficult to integrally mold the opening/closing regulating portion and the hook portion, which have a relatively complicated structure.

[Structure of the invention] (Means for solving the problem) Therefore, in the present invention, the hook part 1 is connected to one end of the base rod part 2, and the bent part 3 is connected to the other end of the base rod part 2. A metal hook A made of a metal hook A, and a hook mounting part 10 that is provided on an actuating body B of a synthetic resin hanger or a synthetic resin clamping tool, and to which the metal hook A can be attached.
The hook mounting portion 10 is formed with an insertion hole 11 into which the bent portion 3 of the metal hook A can be inserted, and a cutout groove 1 communicating with the insertion hole 11.
The bent part 3 of the metal hook A is inserted into the insertion hole 11, and the base rod part 2 is inserted into the notched groove 12.
is housed in the base part 2 of the metal hook A.
By forming the locking pawl 14 which can be locked to prevent the base rod portion 2 from escaping from the notch groove 12, the above-mentioned difficulties can be solved.

(Function) Therefore, the metal hook A is
However, the insertion hole 11 provided in the hook attachment part 10 of the operating body B of a synthetic resin hanger or synthetic resin clamping tool is
The base part 2 is inserted into the hook mounting part 10.
The base rod portion 2 is accommodated in the notch groove 12 , and the locking pawl 14 is locked to prevent the base rod portion 2 from escaping from the notch groove 12 .

In addition, the swinging base rod portion 20 is integrally connected to the base end of the opening/closing actuating portion 21 having a substantially rectangular plate shape at the substantially center of the surface thereof, and the actuating body swinging space 32 of one clamping piece C1.
It is formed to be movable within a.

In addition, the configuration, dimensions, and material of the metal hook A, the specific shape and dimensions of the hook portion 1, base rod portion 2, and bent portion 3, the configuration, dimensions, and material of the hook mounting portion 10, the insertion hole 11, and the notch groove 12. , locking claw 14 and mounting space 1
The specific shape, dimensions, arrangement position, etc. of 5 are not limited to the illustrated example, and can be freely set as appropriate according to the purpose of use, method of use, etc.

[Effects of the invention] Therefore, the present invention provides a metal hook A in which the hook part 1 is connected to one end of the base rod part 2, and the bent part 3 is connected to the other end of the base rod part 2; A hook attachment part 10 that is provided on an operating body B of a synthetic resin hanger or a synthetic resin clamping tool, and to which the metal hook A can be attached.
The hook mounting portion 10 is formed with an insertion hole 11 into which the bent portion 3 of the metal hook A can be inserted, and a cutout groove 1 communicating with the insertion hole 11.
The bent part 3 of the metal hook A is inserted into the insertion hole 11, and the base rod part 2 is inserted into the notched groove 12.
is housed in the base part 2 of the metal hook A.
Since the locking pawl 14 is formed which can lock into the notch groove 12 and prevent the base rod portion 2 from escaping from the notch groove 12, the metal hook A and the hook mounting portion 10 can be manufactured separately.
It becomes easy to manufacture the metal hook A and the hook attachment part 10, and the hook attachment part 1 of the metal hook A can be easily manufactured.
The installation work (assembly work) to 0 can be performed very easily, and the manufacturing cost can be surely reduced. Furthermore, it is easy to mass-produce the actuating body B of the clamping tool, the synthetic resin hanger, etc., and the products can be provided at low cost. Furthermore, it becomes easier to make the operating body B of the clamping tool and the synthetic resin hanger itself smaller and more compact.

Moreover, the metal hook A allows the hook part 1 to
It is possible to further improve the strength, durability, robustness, etc. of the hook part 1 itself, and there is no need to make the hook part 1 itself thick or provide many reinforcing ribs, etc., and the manufacturing of the hook part 1 is simplified. This is very easy, the entire hook part 1 can be formed smartly without being bulky, and the hook part 1 has good hooking functionality. Further, the workability of the metal hook A itself is also improved.

In particular, by forming the locking pawl 14, when the base rod part 2 of the metal hook A is forcibly inserted into the notch groove 12 from the opening 13, the base rod part 2 easily deviates from the notch groove 12. Moreover, the base rod portion 2 is clamped by the inner wall of the notch groove 12 and the locking pawl 14, and its fixed state is improved.
Furthermore, since the bent portion 3 is inserted into the insertion hole 11, the fixed state of the metal hook A in the hook mounting portion 10 is further ensured.
