Description

[Detailed Description of the Invention] This invention relates to a clothespin, particularly a clothespin suitable for hanging.

Examples of conventional clothespins include those shown in Figures 1 to 2.
There is something like the one shown in the figure.

This clothespin 1 consists of a pair of clamping bodies 2 and a spring 3.
The clamping body 2 has hinge parts 4 formed protruding from the center of the clamping body 2, which are joined together in such a manner that the hinge parts 4 are opposed to each other.

The spring 3 is bent into a circular shape as a whole, and after inserting the spring tips 5a and 5b from the inside into a spring guide portion 6 formed on the side of the clamping body 2, the spring 3 is bent into a circular shape. Spring receiving part 7 formed on the outer surface of the lower end
a, 7b.

This spring 3 urges the clamping portion 8 of the clamping body 2 in the direction of arrow A.

When using such clothes pegs 1 to clamp an object to be clamped, such as laundry, the gripping part 9 at the upper end of the clamping body 2 is operated in the direction of arrow B using a finger or the like, and the clamping part 8 is opened, and then an object to be held (not shown) is held by the holding part 8.

In addition, when using the clothespin 1 itself by hanging it,
After inserting the hanging string 10 into the hanging string hole 11 formed in the gripping part 9, the hanging string 10 is wrapped around a clothesline (not shown) or a clothesline, and the object held by the holding part 8 is suspended. I try to support the situation.

However, in such a conventional clothes-drying peg 1, the clamping force of the clamping part 8 is constant, so when the clothes-drying peg 1 is hung and used, the object to be clamped, such as laundry, Due to its own weight, it is easy to separate from the clamping part 8, and depending on the case, the spring tip 5a.

There was a problem in that the spring receivers 5b were separated from the spring receivers 7a and 7b.

This idea was created by focusing on the above-mentioned conventional problems, and when the clothespin itself is used in a hanging manner, the clamping part changes depending on the load of the object being clamped by the clamping part. It is an object of the present invention to provide clothespins that can increase the clamping force.

That is, the clothes rack according to this invention has a pair of left and right clamping bodies each having a clamping part at the lower end and a hinge part approximately in the center, and a spring receiving part between the clamping part and the hinge part. A spring is provided with a pair of legs that are engaged with each other and are bent into a substantially fan shape and have a protrusion at the tip for engagement with a spring receiving part, and a curved part with a condolence mark in the center for connection to a hanging body. In the clothes rack, in which the clamping parts at the lower ends of both clamping bodies can be opened and closed, the spring receiving parts of the clamping bodies have a groove shape that expands upward, and the clamping parts at the lower ends of the clamping bodies can be opened and closed. The main feature is that it consists of a spring leg opening surface for increasing the clamping force according to the load, and stoppers provided at both upper and lower ends of the spring leg opening surface to prevent the spring from coming off.

This invention will be explained below based on the embodiments shown in FIGS. 3 to 6.

In the drawings, parts that are the same as or similar to those in the prior art are designated by the same reference numerals, and redundant explanation will be omitted.

3 to 5 are diagrams showing a clothes rack 12 according to a first embodiment of this invention.

This clothespin 12 consists of a pair of synthetic resin clamping bodies 13 each having a symmetrical shape and structure, and a metal spring 14, and is shown by imaginary lines in FIGS. 4 and 5. A hanging body 16 and a hanging band 1 are attached to the clothesline pole 15.
It is used by being supported in a suspended state via 7.

First, the spring 14 is composed of a leaf spring whose entire outline is bent into a fan shape, and a condolence mark 20 for positioning the hanging body 16 is provided in the center of the curved part 19.
Furthermore, a clamping body 13 is attached to the tip of the pair of legs 21 that protrudes downward.
A protrusion 23a that engages with the spring receiving portions 22a and 22b.

23b is provided.

The leg 21 of this spring 14 is located at the arrow C in FIG.
The spring receivers 22a and 22b are urged in the direction shown in FIG.

Next, the clamping body 13 includes spring receiving parts 22a and 22b between the hinge part 4 and the clamping part 8, and the hinge part 4
A guide portion 6 for inserting the spring 14 is provided at a portion corresponding to the side of the spring 14.

The spring 14 has a pair of legs 21 inserted into the clamping body 13 along the guide part 6, and a spring receiving part 22 provided between the hinge part 4 of the clamping body 13 and the clamping part 8.
By engaging the protrusions 23a and 23b with the protrusions 23a and 22b, the pair of left and right gripping bodies 13 are positioned, and by pressing the spring receivers 22a and 22b, the gripping part 8 is eventually moved in the direction of arrow C in FIG. I'm trying to give it a boost.

The spring receiving portions 22a and 22b have a groove shape that widens diagonally upward from the center line of the clothespin 12, and an inclined spring leg surface 24 that widens upward.
a, 24b, and protrusions 23a, 23 provided on both upper and lower ends thereof.
It consists of a stopper 25 for preventing detachment of the protrusion 23a
, 23b and the spring leg surfaces 24a, 24b are slidable.

Furthermore, on the clamping surfaces 26a and 26b of the clamping part 8, protrusions 27 and holes 28, which can be inserted into and removed from each other, are formed at opposing positions to facilitate clamping of a clamping object (not shown).

A hanging body 16 for hanging the clothespin 12 from the clothesline pole 15 is provided with a hole 29 for inserting the spring 14 at its lower part, and a hole 29 is provided at the both ends of the hanging band 17 on both the front and back sides of the upper part. A pair of protrusions 31 that can be freely engaged with the engagement holes 30 are provided.

Next, the operation of the clothespin 12 according to the first embodiment of this invention will be explained based on FIG. 5.

First, the clothespins 12 are suspended from the clothesline pole 15 via the hanging band 17, and then the gripping part 9 is grasped with fingers, the clamping part 8 is opened, and the object to be clamped (not shown) is held. It is held by the holding part 8.

At this time, the load of the object to be clamped (not shown) is applied to the clamping body 13 in the direction of arrow E, and this load causes the spring leg surfaces 24a, 24b and the protrusions 23a, 23b provided at the tips of the spring 14 to will slide into each other.

Then, the legs 21 of the spring 14 slide as shown by the two-dot chain line F and are pushed and expanded in the direction opposite to the biasing force direction, so that the spring 14 applies a stronger force to the clamping portion 8 and moves in the direction of arrow C. This results in further biasing, and the clamping force increases accordingly.

Figure 6 shows clothespins 3 according to the second embodiment of this invention.
FIG.

The structure of the clothes rack 32 is substantially the same as that of the clothes rack 12 of the first embodiment, but the shape of the spring 33 is somewhat different from that of the first embodiment.

That is, the curved part 34 of the spring 33 is formed to be relatively large so as to protrude laterally from the spring guide part 6, and when the clamping part 8 clamps an object (not shown),
The protrusion 23a of the spring 33 as in the previous embodiment.

23b slides on the open leg surfaces 24a, 24b for springs, and the spring 33 moves upward relative to the pair of clamping bodies 13. As a result, both ends 34a, 34b of the curved portion 34 of the spring 33 are opened for spring insertion. Upper end 35a of guide portion 6.

A pair of clamping bodies 1 while contacting and sliding with 35b.

Then, the expanded force becomes a clamping force on the clamping part 8, which acts in the direction of arrow H, and the clothespins 1 of the first embodiment
The clamping force of the clamping portion 8 is further increased compared to 2.

The other configurations and operations are the same as those in the first embodiment, and their explanations will be omitted.

As explained above, according to this invention, there is a spring opening leg surface for increasing the clamping force between the hinge part and the clamping part of the pair of clamping bodies, and spring leg opening surfaces provided at both upper and lower ends of the spring leg opening surface to prevent the spring from coming off. Since we decided to form a groove-shaped spring receiving part that expands upward and is equipped with a stopper,
The clamping force of the clamping part can be increased according to the load of the clamping object held by the clamping part, and the clamping force of the clamping part can be increased, and the clamping force of the clamping target can be reliably clamped without moving the clamping target such as laundry by 18 fR from the clamping part. be.
