Description

[Detailed description of the invention] This invention relates to a clamping tool for holding, for example, cloth, plastic sheets, etc. used when cultivating agricultural products.

It can be used to stretch between the strung strings, to wrap the ends of fabrics or sheets around strings or wires and maintain the wrapped state, or to cultivate crops by hanging them from the strung wires. The present invention relates to the structure of a clamping tool used when forming an end portion to which a guide rope or the like is attached for guiding.

Conventionally, when fixing fabrics, plastic sheets, etc. to strings, wires, etc., if you tie the string with a string through a hole drilled in the fabric, cracks often occur at the edge of the hole and breakage occurs. Even if it is held by a string, wire, etc. with a U-shaped spring material holding tool, it may be pulled out by wind or other factors, and the mounting stability is lacking.

Therefore, this idea was devised in view of the diagonal point,
In terms of its construction, this device is made of hard plastic with some flexibility.

A pair of left and right gripping bodies that can be folded over each other through a central bending part that gradually becomes thinner as it reaches the center, and that are continuous on both sides and are integrally constructed, and a resilient The opening is biased toward closing and is curved outward, thereby forming a resilient clamping body that is approximately C-shaped in cross section.

Then, by folding a pair of clamping bodies together, a part to be clamped, such as a string or a sheet, is clamped, and the clamped clamping bodies are firmly clamped and pressed together using an elastic clamping body, thereby allowing the clamped part to be clamped. It is something that supports things.

Therefore, when folded, the free ends of the clamping bodies touch each other on the ventral surfaces.

In addition to forming a concave clamping groove for clamping the clamped part,
At least one side of the resilient clamping body is inserted through an insertion hole formed in at least one of the clamping bodies, and the opening is fitted into a receiving groove recessed in the back surface of the free end of the clamping body. so that the free ends are pressed against each other in a way that makes sense.

Furthermore. In order to maintain the combination of the clamping body and the resilient clamping body and to prevent them from separating, the resilient clamping body is made movable along the direction in which the clamping bodies are continuous with each other, and the central bent portion When moving to the side, the free end of one of the clamping bodies, while being clamped at the opening, contacts the inner outer surface of the first elastic clamping body or contacts the inner surface of the opening. The abutting/removal preventing portion for restricting the elastic clamping body from being pulled out from the clamping body is formed at the central bent portion when the clamping body is folded up.

Therefore, the object to be clamped is clamped in the concave clamping grooves formed on the ventral surfaces of the pair of left and right clamping bodies that are folded over each other, and the free ends of the pair of left and right clamping bodies abut each other. By fitting the opening of the elastic clamping body into the recessed receiving groove, the back side is clamped, so the object being clamped is securely supported and does not easily come off, making it stable to wear. The properties are extremely good.

Also, folding of the clamping bodies with each other is possible. This is done through the central folding part, but since this central folding part gradually becomes thinner as it reaches the center, the folded part after folding does not protrude too much and becomes a mountain shape. Not only is it easier to handle.

Bending work is also easy.

The combination of the elastic clamping body with the clamping body is extremely simple because it is carried out by inserting at least one side of the resilient clamping body through an insertion hole formed in at least one of the clamping bodies. Moreover, the first elastic clamping body itself is movable along the direction in which the clamping bodies are continuous, and in this case, the opening of the resilient clamping body always clamps the free end, so it is easy to move. will not be removed.

Also, what is the opening of the 1st pressure clamping body? Since it is curved outward and narrowed, movement with the cotton with the free end pinched is difficult.
It can be moved smoothly in any direction, and the part to be held can be clamped easily.
Or, the release work will not be repeated.

In addition, the movable elastic clamping body contacts the inner outer surface of one elastic clamping body while the free end of one of the clamping bodies is clamped at the opening. Alternatively, a contact/removal prevention part that contacts the inner surface of the opening and restricts the elastic clamping body from being removed from the clamping body may be formed at the central bent part when the clamping body is folded. This prevents the member from being pulled out or separated from the clamping body even after the clamping action is released, thereby preventing the member from being lost during repeated use and making it easy to handle.

At this time, since the resilient clamping body remains attached to one of the clamping bodies, it does not interfere with the opening operation of the left and right clamping bodies.

The movement of the resilient clamping body after the clamping bodies are mutually closed in order to clamp the object is also easy due to the fact that the opening is curved outward.

Since the elastic clamping body has a substantially C-shaped cross section with the narrowed opening biased to elastically close, the free end rear surface that clamps the object to be clamped in the clamping groove. The clamping pressure of the grip is extremely large, and it can withstand external shocks and vibrations.

Further improves the stability of pressure bonding.

The pair of clamping bodies are made of a hard plastic that has some flexibility, so the characteristics of the material allow for simultaneous molding of each part, eliminating the need for assembly. This makes it possible to integrally and continuously construct all the clamping bodies, and since the number of parts is reduced, it can be provided at low cost.Furthermore, by replacing only the elastic clamping bodies, the clamping pressure can be increased. The degree of intensity can be changed.

Hereinafter, embodiments of this invention will be described with reference to the drawings.

In the first embodiment shown in FIGS. 1 to 6, a pair of left and right clamping bodies 1.2 are made of a hard plastic having some flexibility, such as polypropylene resin, and are transported to Central America. It can be folded over via the thinner central bending part 3.

It is constructed in a continuous manner on both sides, and apart from this,
A substantially U-shaped elastic clamping body 15 made of a band-shaped spring material is formed in the narrowed cross section of the opening 16, and both 1.2.
15 are used in combination.

That is, in order to combine the resilient clamping body 15 with the folded clamp bodies 1 and 2, an insertion hole 1 is provided in each of the clamp bodies 1 and 2.
0 is drilled and formed Q, the free ends of the former 1 and 2 are inserted into the opening 16 of the latter 15, and the inner part 1 of the latter 15 is inserted.
, 7 are positioned in the insertion hole 10, and the latter 15
(See Figure 5).

In addition, the grooved surfaces of the clamping bodies 1 and 2 that come into contact with each other at the free ends of the clamping bodies 1 and 2 when folded over each other are provided with a semicircular shape, a short shape, etc. corresponding to the outer shape of the clamped object 9 such as the string 18 and the sheet 19. concave clamping grooves 4 and 5 are formed.

A receiving groove 6,7 into which the opening 16 is fitted is formed on the back surface of the free end, and the receiving groove 6,7 is a clamping groove. Compared to the bulges 11 and 12 formed on the back surface corresponding to positions 4 and 5, the free end edge of the free end portion is located in front of the bulges 11 and 12 formed on the back surface, and is curved outward. When the opening 16 of the repellent and pinching body 15 moves along the bulge LL12, it is forcibly expanded.

When it runs along the receiving grooves 6 and 7, it is closed by elastic force (see FIGS. 5 and 6).

In this way, the resilient clamping body 15 is made movable within the insertion opening 10 of the clamping body 1.degree. 2 along the direction in which the clamping bodies 1 and 2 are continuous with each other.

Furthermore, when moving the first elastic pinching body 15 toward the central bent portion 3, the central bent portion 3 at either one free end
An abutment that comes into contact with the outer surface of the inner part 17 of the resilient clamping body 15 that is slightly retracted inward while the clamping retaining part 8 formed on the side edge is clamped in the opening 16. The contact/removal preventing portion 9 is located at the center bent portion 3 when the clamping body 1°2 is folded over.
to form.

That is, the first elastic clamping body 15 itself moves only within the insertion openings 10 of the clamping bodies 1 and 2, and is moved to the side of the central bent portion 3.
When the outer surface of the inner part 17 comes into contact with the abutment/removal prevention part 9, the clamping force applied to the free ends of the clamping bodies 1 and 2 by the rear surface is released, and the clamping bodies 1 and 2 are released. They are opening up and turning away.

Therefore, the free end structures of each of the clamping bodies 1 and 2 are not exactly the same, and as shown in the figure, there is a stepped portion 2 that fits into the ventral surface of one of the free ends of the other.
2, and this bump portion is used as a clamping/removal preventing portion 8.

When this is used, the clamping bodies 1 and 2 are made foldable, one side of the elastic clamping body 15 is inserted through the insertion opening 10, and the clamping/removal preventing part 8 is clamped at the opening 16. , and the outer surface of the inner part 17 is kept in contact with the contact/disengagement prevention part 9 (see FIG. 5).

Then, the string 18. At the same time as the sheet 19 is fitted, the elastic pinching part 15 is pinched and compressed with the fingertips to move the free edge of the free end forward, and the opening 16 is inserted into the receiving grooves 6, 7.
By fitting the string 18. The seat 19 is firmly supported (see FIG. 6).

In addition, 13 and 14 in the figure are the central bent portions 3 of the clamping bodies 1 and 2.
- This is a notch insertion portion provided on the inner edge of the insertion opening 10 in the vicinity, which can prevent the inserted string and other items from shifting.

A second embodiment is shown in FIGS. 7 to 13, and the symbols shown in FIG. 1 are exactly the same as those in the first embodiment.

However, the insertion hole 10 is formed by opening only in one of the clamping bodies 2. 1. The shape of the resilient clamping body 15 is approximately oval in cross section. 1. This is the means for preventing the resilient clamping body 15 from coming off. This embodiment differs from the first embodiment in that the clamping force is utilized only on the inner surface of the opening 16 of the opening 15, and this will be specifically explained below.

That is, one of the clamping bodies 1 does not have an opening 10 formed therein, and the folded clamping bodies 1 and 2 and the elastic clamping body 1
In combination with 5, only one side of the elastic clamping body 15 is connected to the insertion port 1.
0, the opening 16 is clamped by the clamping/removal prevention part 23 that exists between the free end of the clamping body 1 and the central bent part 3.

The central bent portion 3 has a wall thickness larger than the opening width of the opening 16, and has a stepped structure that fits into each other, so that a contact portion that comes into contact with the inner surface of the opening 16 is formed. A retaining portion 20.21 is formed.

As a result, in the first embodiment, in order to bring the outer surface of the inner part 17 of the resilient clamping body 15 that has been moved toward the center bent part 3 into contact with each other, and to maintain this contact state, However, in this second embodiment, removal from the clamping bodies 1 and 2 is restricted only by the clamping action of the opening 16, so the back surface of the free end is not visible. The shape and structure of the elastic clamping body 15 can be freely selected as long as the distance of movement for achieving the clamping pressure and its release is ensured.

Furthermore, its use in this second embodiment is as follows.

It is almost the same as that of the first embodiment, except that when the clamping action by the elastic clamping body 15 is released, the clamping release prevention part 23
The inner surface of the opening 16 comes out of contact with the center stop 2 when the
