Description

[Detailed Description of the Invention] [Industrial Field of Application] This invention relates to an improvement of the fulcrum part of a pinch for appropriately holding pants, skirts, and other objects.

[Conventional technology]

Conventionally used pinches have supporting parts connected inward from both left and right ends of the gripping piece at approximately the center.
The support parts of the pair of clamping pieces are stacked one on top of the other, a shaft is passed through the tip of the support part, a torsion coil spring is inserted through the shaft, and both ends of the spring are stopped at the upper part of the inner surface of each clamping piece. The separation in such a pinch is caused by the swinging of the clamping piece around the axis.

[Problem that the invention attempts to solve]

However, this conventional technique has the following disadvantages.

Since a strong force is applied directly to the shaft, which is the center of the swing, from the coil spring, there is a risk that the shaft or the shaft locking portion of the support piece may break, and the two assembled clamping pieces may come apart.

Further, since the gripping piece swings around the swinging center (axis) where the force is most concentrated, using two locking portions as fulcrums, the movement is hard and rough.

Therefore, the object of this invention is to provide a pinch that allows smooth and stable pinching and separation without the pinching pieces disassembling.

[Means for solving problems]

In order to solve the above technical problem, this invention
Arc-shaped arms 6 are provided on the left and right sides of the inner surface of the clamping piece 1, and an arc-shaped guide hole 7 is provided in the upper arm 6a of the arm 6 on one side, and a pin 8 is provided in the outer end surface of the lower arm 6b.
A pin 8 is provided in the upper arm 6a of the other side arm 6, and a guide hole 7 is provided in the lower arm 6b. Insert pin 8 into guide hole 7 at 4 locations on 6b.
The pin 8 is inserted into the guide hole 7 so that the pin 8 can freely reciprocate in the guide hole 7.

[Effect]

The pinch of this invention is the left and right arms 6 and 6 of the clamping piece 1.
Since one pin 8 is provided upside down on each side, the clamping piece 1 is supported at the diagonal position of the left and right upper and lower arms 6a and 6b, and when the two clamping pieces 1 are combined, there are a total of 4 pins 8. Since the two pins 8 support each other, the two clamping pieces 1 can be stably and firmly connected to each other and will not come apart.

Furthermore, since the pin 8 of the other clamping piece 1 reciprocates while being guided by the guide hole 7 of one clamping piece 1, the operation of the clamping piece 1 can be made smooth and stable.

〔Example〕

An example showing a specific example of this invention will be described below.

The pinch is composed of a pair of clamping pieces 1 and a coil spring 2, as shown in FIGS. 1 and 2.

The clamping piece 1 consists of a knob part 3 on the outer surface of the upper part, a joint part 4 in the almost middle part, and a clamping part 5 at the lower part.

The joint part 4 has arcuate arms 6, 6 arranged in a row inward from near both left and right ends of the inner surface of the clamping piece 1, and an arcuate guide hole 7 is formed in the upper arm 6a on the left side toward the inner surface of the clamping piece 1 in a penetrating manner. The arm 6 and the guide hole 7 are both aligned with the swing center O of the clamping piece 1 as shown in FIG.
The left lower arm 6b has a pin 8 protruding outward from its tip, and the right upper and lower arms 6a and 6b are vertically different from the left upper and lower arms 6a and 6b. Conversely, the guide hole 7 and the pin 8 are formed, that is, the upper arm 6 as shown in FIG.
A pin 8 is formed in the lower arm 6b, and a guide hole 7 is formed in the lower arm 6b. A stepped portion 9 is formed at the base of the inner surface of the arm (left upper arm 6a, right lower arm 6b) provided with the guide hole 7, and as the gripping piece 1 is separated from the stepped portion 9, the other gripping piece 1 is attached to the stepped portion 9. It is assumed that the tips of the upper and lower arms 6a and 6b are fitted into the upper and lower arms 6a and 6b.

An annular groove 10 is provided on the inner surface of the upper surface of the clamping piece 1.
A coil spring 2 is locked between the annular grooves 10 of the two clamping pieces 1, and the repulsive force of the coil spring 2 urges the lower parts of the two clamping pieces 1 into contact to obtain a clamping force.

A clamping member 11 is fitted in the center of the clamping portion 5 so as to prevent it from coming off.

To assemble the clamping pieces 1, as shown in FIG. Right upper and lower arms 6 of clamping piece 1
a and 6b face each other, and the guide hole 7 and pin 8 form a pair at four upper and lower locations, and then both the upper and lower arms 6a and 6b of the two opposing clamping pieces 1 are elastically deformed, and the pin 8 is inserted into each pin 8. It is inserted into the guide hole 7. As shown in FIG. 3, the pin 9 is guided by the guide hole 7 and reciprocates, allowing smooth pinching and separation. Also, since the other arm 6 fits into the step,
The operation of the clamping piece is smooth, and the arms 6 of the other clamping piece 1 do not protrude outward from the sides of the clamping piece 1 to the left and right.

In addition, the pinch of this invention can be used not only when used alone, but also as a hanger, in which case the joint part 4
The hanger is used by passing the shaft of the hanger body through a circular space formed in the center of the left and right upper and lower arms 6a and 6b.

[Effect of idea]

This invention has the following effects.

2 because the pins 8 are provided at diagonal positions of the left and right upper and lower arms 6a and 6b of the clamping piece 1, and the two combined clamping pieces 1 are supported by a total of four pins 8.
The clamping pieces 1 are firmly connected and will not come off.

Furthermore, since the pin 8 of the other clamping piece 1 reciprocates while being guided by the guide hole 7 of one of the clamping pieces 1, the pinch separation becomes smooth and stable.
