Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a versatile clip that can be used like clothespins, trouser hangers, clips used in laundry shops, and other clips.

Conventionally, as this type of clamping tool, for example,
The clip described in Publication No. 51-98462,
There is a clamping tool described in Utility Model Publication No. 54-31044. There are also a clothespin described in Japanese Utility Model Publication No. 48-26905 and a hanging clip described in Japanese Utility Model Publication No. 49-101934.

However, the latter of the above-mentioned clamping tools can only exert enough clamping force to lightly hold thin and lightweight objects, and the former can only swing the operating member like a lever. The pair of clamping plates can be opened and closed, but a coiled spring is used to open the clamping part at the tip of the pair of clamping plates, and this spring is attached to the center of the clamping plate. Because it is arranged so that
The problem is that the clamping tool itself has many components, and the operating member is placed at the proximal end of the clamping plate, making it difficult to construct the clamping tool compactly. There was a problem in that the applied force was not sufficiently exerted at the clamping portion at the tip of the clamping plate, and a portion of the force was easily consumed as a force that bent the clamping plate itself.

Therefore, the present invention solves the above-mentioned difficulties,
It was created with the aim of providing the best clamping tool.

Accordingly, a pair of clamping pieces each having a clamping part at the tip and an opening/closing center part at the base end are connected to each other via a resiliently bent piece connected to the base end of the pair of clamping pieces. and a substantially elliptical gripping body which is housed in an actuating body housing part opened in each of the pair of clamping pieces, and is capable of accommodating regulating protrusions protruding from the left and right side walls of each of the actuating body housing parts. It consists of an actuating body comprising an opening/closing regulating part with recesses formed on the left and right sides, respectively, and the clamping body can be opened and closed freely around the opening/closing center, and the elastic bending piece itself can be opened and closed. The elastic force is always biased in the direction of opening the clamping part, and in the swinging motion of the operating body, the regulating protrusion of one clamping piece and the regulating protrusion of the other clamping piece are tightened on the inner circumferential wall surface of the recess of the opening/closing regulating part, When the regulating protrusion is regulated by the inner circumferential wall surface of the recess facing each other in the longitudinal direction, the clamping part of the clamping body becomes a non-clamping state, and when the regulating protrusion is regulated by the inner circumferential wall surface of the recess facing each other in the transverse direction, the clamping part becomes the clamping body. The gist of the present invention is that the clamping portion is formed to be in a clamping state.

Embodiments of the present invention will be described below with reference to the drawings.

The clamping tool of the present invention is a clamping member A made of polypropylene, dyuracon, or other appropriate synthetic resin material.
and an actuating body B having an opening/closing regulating section 10.

The clamping body A has a pair of clamping pieces A1 and A2 having a clamping part 6 at the tip and an opening/closing center part 1 at the base end.
Both ends thereof are connected to each other via a spring-shaped bending piece 2 which is connected to the base ends of a pair of holding pieces A1 and A2. The clamping body A is formed so that the clamping part 6 can be opened and closed freely around the opening/closing center part 1, and the elastic force of the elastic bending piece 2 itself always biases the clamping part 6 in the opening direction. ing. Further, in the clamping body A, the opening/closing regulating part 10 of the working body B or the working body accommodating part 3 that accommodates the entire working body B is attached to the clamping pieces A1, A2.
Each of the actuator accommodating portions 3 is opened at its center, and regulating protrusions 4 are provided at predetermined positions on the left and right side walls of each of the actuating body accommodating portions 3, respectively.

The actuating body B is formed by recessing approximately elliptical recesses 10a in which the regulating protrusion 4 can be accommodated on the left and right side surfaces of the opening/closing regulating part 10, respectively, and the actuating body B is attached to the clamping body A using the regulating protrusion 4 as a fulcrum. It is possible to swing freely. By the way, when the actuating body B swings, the inner circumferential wall surface 11 of the recessed part 10a of the opening/closing regulating part 10 tightens the regulating protrusion 4 of one clamping piece A1 and the regulating protrusion 4 of the other clamping piece A2, and Opposing recess 10a inner peripheral wall surface 11
When the regulating protrusion 4 is regulated, the clamping part 6 is in a clamping state, and the recessed part 10 facing in the longitudinal direction
a The clamping portion 6 is formed so as to be in a non-clamping state when the regulating protrusion 4 is restrained by the inner circumferential wall surface 11.

In addition, 12 in the figure is an engaging part 5 formed on the clamping body A.
A locking portion that removably engages with the locking portion 12.
are inner circumferential wall surfaces 11 of the recess 10a facing each other in the transverse direction.
When the regulating protrusion 4 is regulated and the clamping part 6 is in the clamping state, it is formed so as to engage with the engaging part 5 in order to maintain this state. In the figure, reference numeral 13 indicates a mounting portion, and this mounting portion 13 may be formed integrally with the actuating body B as a hook shape that can be easily hung as shown in FIG. It may also have a C-shape (not shown) having a notch so that it can be hung on a horizontally suspended wire, string, or the like. Furthermore, as shown in Fig. 9, it may be shaped like a frame to which the ends of the string can be connected, and may be formed separately from the actuating body B and the clamping body A. It can be set freely as appropriate.

14 is a recessed portion 10 of the opening/closing regulating portion 10 of the operating body B.
This is a protrusion passage notch provided so that the regulating protrusion 4 and the like can be accommodated without being damaged when the regulating protrusion 4 is forcibly accommodated in a.

The clamping body A is bent in two against the elastic force of the elastic bending piece 2, and the pair of clamping pieces A
The opening/closing center portions 1, A2 of the opening/closing center portions 1, 1 are fitted together so that they can be opened and closed freely. The opening/closing center parts 1, 1 may be formed so as to be able to smoothly open and close the clamping body A without shifting its axis, and as shown in FIG. It may be constructed by providing a fitting protrusion in the center part 1 and a fitting hole in the opening/closing center part 1 of the other clamping piece A2, or as shown in FIG. It may be configured by opening/closing center parts 1, 1 that fit the part 13, or,
A structure in which a plurality of actuating bodies B can be attached to the clamping body A (for example, horizontally long clamping pieces A1 and A2 are formed,
The actuating bodies B may be attached to both end portions in the longitudinal direction to make the clamping portion 6 longer, or other settings may be made as appropriate.

The regulating protrusion 4 of the clamping body A has its tip end inclined or curved so that the opening/closing regulating part 10 can be accommodated in the recess 10a without difficulty, and once accommodated, it will not be easily released from the accommodated state. It may be formed into an arc shape or the like (see Fig. 7).

In addition, a swing stop piece 7 is provided on the clamping body A to limit the swing range of the actuating body B (for example, 90 degrees) so that the regulating protrusion 4 does not deviate from the protrusion passage notch 14 of the opening/closing regulating part 10. (See Figure 4).

Recessed portion 10a in opening/closing regulating portion 10 of operating body B
The front shape of the inner circumferential wall surface 11 is such that when the regulating protrusion 4 is controlled by the inner circumferential wall surface 11 of the recessed portion 10a facing in the transverse direction, the clamping state of the clamping portion 6 is obtained (see FIGS. 4 and 11). (see figure), when regulating the regulating protrusion 4 with the inner peripheral wall surface 11 of the recessed part 10a facing each other in the longitudinal direction, the clamping part 6 is in the non-clamping state (see Figs. 3 and 10), and the clamping part 6 is not clamped. It may be of any kind as long as it can smoothly change from the state to the clamped state. Furthermore, in order to stabilize the clamping state of the clamping part 6, the inner circumferential wall surface 1 of the recessed part 10a facing in the transverse direction is
1 may be formed with a recess for shallowly accommodating the regulating protrusion 4 (see FIG. 11). Furthermore, the depression may be used as the locking portion 12 and the regulating protrusion 4 may be configured as the engaging portion 5. Alternatively, a recess for accommodating the regulating protrusion 4 may be formed in the inner circumferential wall surface 11 of the recess 10a facing each other in the longitudinal direction to prevent the actuating body B from wobbling and to prevent it from swinging unnecessarily. (See Figure 10).

If the engaging part 5 and the locking part 12 are formed so that they can be engaged with each other when the clamping part 6 is in the clamping state and maintain this clamping state, the engaging part 5 and the locking part 12 can be used in the illustrated example (FIGS. 4 and 1).
It can be set freely as appropriate without being limited to Figure 1). The engagement between the engaging portion 5 and the locking portion 12 and their release are performed by deforming the actuating body B, the clamping body A, or both within the elastic limit.

In addition, the shape of the clamping portion 6 is shown in the illustrated examples (Figs. 1 and 9).
It can be set freely as appropriate without being limited to the figure).

Therefore, according to the clamping tool according to the present invention, the clamping tool is constituted by the clamping body A and the operating body B, which are formed by connecting the pair of clamping pieces A1 and A2 with the elastic bending piece 2 interposed therebetween. , it is possible to reduce the number of component parts of the clamping tool itself.

In addition, a pair of clamping pieces A1 and A2 having a clamping part 6 at the tip and an opening/closing center part 1 at the base end are elastically bent so that both ends thereof are connected to the base ends of the pair of clamping pieces A1 and A2. The clamping body A is formed by being connected via the piece 2, and the opening/closing regulating part 10 of the working body B is accommodated in the working body accommodating part 3 opened in each of the pair of clamping pieces A1 and A2. It becomes easier to make it smaller and more compact.

In particular, regulating protrusions 4 are provided protrudingly on the left and right side walls of each of the actuating body accommodating portions 3, respectively, and approximately elliptical recesses 10 in which the regulating protrusions 4 can be accommodated are provided on the left and right side surfaces of the opening/closing regulating portion 10.
a is provided in a recessed manner, and in the swinging motion of the actuating body B, the regulating protrusion 4 of one clamping piece A1 and the regulating protrusion 4 of the other clamping piece A2 are tightened on the inner circumferential wall surface 11 of the recessed part 10a of the opening/closing regulating part 10. Because of this structure, the swinging operation of the actuating body B can be performed stably and smoothly without wobbling in the left and right directions, and a strong and well-balanced clamping force can be obtained, and the structure of the clamping tool itself is robust. It can be configured to be difficult to damage.

Further, recesses 10a facing each other in the longitudinal direction of the oval shape
When the regulating protrusion 4 is regulated by the inner circumferential wall surface 11, the clamping part 6 of the clamping body A is in a non-clamping state, and the regulating protrusion 4 is regulated by the inner circumferential wall surface 11 of the recessed part 10a facing in the short direction of the oval shape. When the clamping part 6 of clamping body A is
Since it is formed to be in a clamped state, the degree of opening of the clamping part 6 can be changed to be larger or smaller by simply changing the ratio of the distance between the recessed part 10a and the inner circumferential wall surface 11 in the longitudinal direction and the transverse direction. It becomes like this. Moreover, the restriction of the restriction protrusion 4 by the inner circumferential wall surface 11 of the recessed portion 10a can be performed very smoothly, and the swinging operation of the actuating body B can be performed without requiring strong force.
