Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fastener which can easily and quickly tighten a connecting tool for connecting end portions of building boards adjacent to each other in the width direction.

[0002]

2. Description of the Related Art Conventionally, as shown in FIGS. 9 and 10, in a building plate constituting an outer enclosure such as a roof or a wall, a cap is attached to a connecting end portion of the building plates adjacent in the width direction. There are many types of materials that cover and connect, but in many of them, not only can a cap material be covered, but it can also be locked to the connecting bent portion of the building boards under the cap material. The connection may be further strengthened while using the connector.

[0003]

As described above, in the case of building plates adjacent to each other in the width direction, in order to use the connecting tool, when the opposite ends of the adjacent building plates are connected, Fixing the opposing ends of the working plates with the connecting tool while closely contacting each other requires an extremely large force, and a great burden is imposed on the worker.

[0004]

Therefore, as a result of earnest studies to solve the above-mentioned problems, the inventor has found that the present invention can be applied to a locking fixed body having a locking portion at the tip and a pressing force for locking at the tip. And a pressing member having a lever at the other end, and the locking pressing portion of the pressing member is located closer to the tip end side of the pressing member than the pressing member. In addition, since the locking fixed body is a tightening tool that is rotatable in the front-rear direction of the pressing operation body so that the locking portion can substantially face the locking pressing portion, the width direction can be efficiently applied with a small force. It is possible to tighten and fix the opposing end portions of the building boards adjacent to each other, thereby solving the above problem.

【Example】

An embodiment of the present invention will be described below with reference to the drawings. The fastener of the present invention is mainly composed of a locking fixed body A and a pressing operation body B as shown in FIGS. Composed,
First, the locking fixture A has a locking portion 1a at the tip of the fixed main body 1.
Are formed. Although there are various examples of the fixed main body 1, the specific examples are as follows.
A metal rod having a circular cross section or the like is used, and the metal rod is bent and formed in a gentle substantially arc shape or a flat V shape.

The locking portion 1a of the locking fixed body A is formed by bending the tip of the fixed main body 1 in a folded shape. The locking portion 1a has a structure in which it can be locked at the end portions in the width direction of the connection winding plate 16 of the building boards C, C described later. At the other end of the fixed main body 1,
As shown in, a pivot base 2 is provided. The pivot base 2 is specifically formed in a cubic shape, and the pivot base 2
The fixed main body 1 is fixed to the base body 2, and the pressing body B is pivotally supported on the pivot base portion 2.

The fixed main body portion 1 can be appropriately moved within a predetermined range of the distance from the pivotal support base portion 2 to the locking portion 1a. As a concrete structure, FIG. ), An outer screw portion 1b is formed on the fixed main body portion 1 in the shape of a shaft, and the outer screw portion 1b is connected to the pivot base portion 2
It is inserted into the adjusting through hole 2a formed in the above, and both sides of the adjusting through hole 2a are fixed by fixing fixtures 3 such as nuts.

By appropriately adjusting the fixing fixtures 3, 3 with respect to the outer screw portion 1b of the fixed main body 1, the fixed main body 1 can be moved in a predetermined range in the axial direction, As shown in FIG. 2A, the position of the locking portion 1a can be finely adjusted.

The cap member 14 is fitted and fixed between the fitted bent portions 13 and 13, and this is sequentially repeated to construct the envelope.

[0024]

According to the present invention, the locking portion 1a is provided at the tip.
And a pressing member B ₁ having a locking pressing portion 6 and a pressing support portion 7 at its tip and a lever 9 at the other end, respectively. B
The locking pressing part 6 is located closer to the tip end side of the pressing actuating member B than the pressing supporting part 7, and the locking fixing member A is arranged so that the locking part 1a can substantially face the locking pressing part 6. By using a fastener that is rotatable in the front-back direction of B, firstly, the construction boards C and C can be connected very simply and quickly, and secondly, the structure can be made extremely simple. Is something that can be done.

The above effect will be described in detail. A locking fixed body A composed of a locking pressing portion 6 and a pressing support portion 7, a pressing actuation body B provided with a lever 9 at the other end, and a locking portion at the tip. 1
Since it is composed of the locking fixture A having a, the locking portions 1a of the locking fixture A are adjacently opposed to each other when temporarily fixing and connecting the building boards C, C, ... The connecting winding plates 16 are placed adjacent to each other only by locking one of the connecting winding plates 16 overlaid on the building plates C, C, applying the locking pressing portion 6 to the other, and then operating the lever 9. The building boards C, C facing each other can be temporarily and firmly fixed very easily (see FIGS. 4 to 8). The above-mentioned work can be performed almost instantaneously, and work efficiency can be improved.

Next, the tightening tool of the present invention comprises a locking fixture A,
It is composed of a pressing operation body B, and the pressing operation body B has an extremely simple shape, can minimize the number of parts, and can be provided at an extremely low price.

Next, in claim 2, the pressing support portion 7
Is a cylindrical roll, and is a rotatably provided at the tip of the pressing body B, so that the construction plates C, C, ... You can

The above-mentioned effects will be described in detail. Since the pressing support portion 7 has a cylindrical roll shape and is rotatably provided, the pressing actuator B can be rotated very easily around the pressing support portion 7. Thus, the operation can be efficiently performed (see FIGS. 3, 4 and 8).

That is, when the locking pressing part 6 bends the winding part 16a of the connecting winding plate 16 around the cylindrical roll-shaped pressing support part 7 of the pressing body B ₁ , the pressing support part 7
However, as shown in FIG. 8, the contact between the pressing support portion 7 in the form of a cylindrical roll and the building board C moves slightly from the initial contact point S ₁ to the final contact point S _{2 as shown} in FIG. Since the portion 7 is directed from the outside to the inside of the fitted bent portion 13 of the building board C, the engagement pressing portion 6 further bites deeply into the back surface side of the fitted bent portion 13 of the building board C. Therefore, the bending work of the winding portion 16a of the connecting winding plate 16 can be performed without difficulty and reliably.
