Abstract

PURPOSE:To eliminate possible hazards, for example, an injury of a worker which may be inflicted upon when a bolt or the like strikes on his leg or the like and a downfall of a worker which may be caused when his work clothes are caught on the bolt or the like, and to prevent the drop of a clamp even if it is subjected to slight impact in a mounted state. CONSTITUTION:A pair of lateral members 1 and 2 are continuously installed by way of a hinge 3 so that they may be opened freely where pipe holes 4 and 5, which allow a pipe to be inserted in the vertical direction to the hinge 3, are bored. Slits 6 and 7 are installed to a lateral end on the opposite side of the hinge 3 in each of the lateral bodies 1 and 2, which are expandable to allow the pipe to be inserted by opening the pipe holes 4 and 5 with the outside and elastically deforming the edges. Furthermore, there are installed to each of the lateral members 1 and 2 a removable engagement hook 8, which fixes a closed state of the lateral members 1 and 2 and an engagement receiving part 9, thereby producing hard synthetic resin molded products.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a clamp cover for covering a clamp fitting used for connecting a vertical pipe and a horizontal pipe when assembling a temporary scaffold or the like at a construction site.

[0002]

2. Description of the Related Art In a conventional general clamp fitting, one end of a pipe retainer that is also curved in a substantially semicircular shape is pivotally attached to one end of a pipe receiver that is curved in a substantially semicircular shape, and the other end is openable and closable. , Two sets of which the closed state is fixed with bolts and the like are provided, they are connected by a universal joint, one of the pipe holder and the pipe holder is attached to the vertical pipe, and the other pipe holder and the pipe holder are attached. It is designed to be attached to a horizontal pipe.

Therefore, when the clamp metal fitting is attached, there is a risk that the bolt or the like may project and the operator's leg or the like may hit the leg and be injured, or the operator's clothing may be caught by the operator and cause a fall. It was

Therefore, as a solution to such a problem, as disclosed in Japanese Utility Model Publication No. 4-50358,
There has been proposed a clamp cover configured to cover the clamp fitting by a pair of hard dividing members, one end of which is pivotally attached and the other end of which is detachable.

However, in the clamp cover of the above-mentioned known example, the hinge portion is parallel to the axial direction of the pipe, and when this is attached to the clamp metal fitting, the hinge portion is attached to the outside of the clamp metal fitting. Since it is necessary, the locking portion provided at the end opposite to the hinge is located inside the clamp fitting, which restricts the structure of the locking portion. As shown in the example, it was necessary to have a structure in which thin locking pieces are projected on both sides of the end. Therefore, the structure of the locking portion of this known example does not depend, and for example, when the operator accidentally kicks it with his / her foot when moving, the locking piece bends and the hooked portion provided at the tip thereof is There is a possibility that the clamp cover may be easily detached from the locking ear portion and the clamp cover may be opened and dropped.

[0006]

SUMMARY OF THE INVENTION Therefore, according to the present invention, the legs or the like of an operator may be hit by a bolt or the like for fastening a clamp fitting, or the worker's clothes may be caught on the bolt or cause a fall. An object of the present invention is to provide a clamp cover that can eliminate danger and that will not fall off even if a slight shock is applied in the mounted state.

[0007]

In order to achieve the above object, in the clamp cover of the present invention, a pair of side bodies 1 and 2 are connected in a freely openable and closable manner via a hinge portion 3 to form each side body 1. ，
2 is provided with pipe holes 4 and 5 for penetrating the pipe in a direction perpendicular to the hinge portion 3, and the side surface members 1 and 2 have pipe holes 4 and 5 at side ends opposite to the hinge portion 3. 5 and the outside are opened and the edges are elastically deformed to provide slits 6 and 7 that can be expanded to such a width that the pipe can pass through. It is characterized in that a hard synthetic resin molded product is provided by providing a locking hook 8 and a locking receiver 9 which can be engaged and disengaged to fix the closed state of the side bodies 1 and 2 by mating. is there.

[0008]

The clamp cover of the present invention is provided with the side bodies 1 on both sides.
Since the hinge portion 3 that connects the two is made perpendicular to the pipe holes 4 and 5, when it is attached to the clamp fitting, the pipe is not sandwiched as in the above-mentioned known example, and the pipe holes 4 and 5 are The pipe is pushed in through the side slits 6 and 7. Therefore, on the contrary, when removing from the pipe, it is necessary to elastically deform the edges of the slits 6 and 7 to widen the width of the slits 6 and 7, but such an operation must be performed intentionally, It is extremely unlikely to occur due to an accident such as a worker's foot hitting during work. Therefore, the clamp cover of the present invention does not drop even if it receives some impact.

[0009]

Embodiments of the present invention shown in the drawings will be described below. First, FIG. 1 and FIG. 2 show a state in which the clamp cover 10 is unfolded. This clamp cover 1
Reference numeral 0 has laterally symmetrical side bodies 1 and 2, respectively, which are connected in series by a hinge portion 3 interposed at an intermediate position. As shown in FIG. 2, the side bodies 1 and 2 have a substantially bowl-shaped three-dimensional shape, and have circular pipe holes 4 and 5 at the bottom thereof, and slits that open the pipe holes 4 and 5 to the outside. 6 and 7 are provided at the side end portions on the opposite side of the hinge portion 3. The edges of the slits 6 and 7 can be elastically deformed, and the width of the slits 6 and 7 can be expanded. Each of the side bodies 1 and 2 has peripheral walls 11 and 12, but notch windows 13 and 14 are provided on the peripheral wall at the side end opposite to the hinge 3. Further, a tongue-shaped piece 15 is projected outward at both sides of the cutout window portion 13 on the peripheral wall of the one side body 1, and a locking hole 16 is bored in the tongue-shaped piece 15 to lock the structure. The receiving portion 9 is provided, and at the position corresponding to the locking receiving portion 9 on the peripheral wall 12 of the other side surface body 2, the locking hole 16 of the locking receiving portion 9 can be inserted and engaged. The hanging portion 8 is projected.

Next, FIG. 3 and FIG. 4 show the clamp cover 1
0 shows the usage state of 0. The clamp cover 10 in the expanded state is bent at the hinge portion 3 and the side bodies 1 and 2 on both sides are closed, so that the clamp metal fitting 17 fixed to the pipe 18 by being fastened with the bolt 19 is covered. Then, the slits 6 and 7 are pushed into the pipe holes 4 and 5 of the side bodies 1 and 2 which are perpendicular to the hinge portion 3, and the pipe 18 is fitted therein. In addition, by engaging the locking hook 8 with the locking receiver 9,
The closed state of is fixed. The clamp cover 10 is made of a hard synthetic resin so that the protrusions such as the bolts inside the clamp cover 10 are not touched even when stepped on with a foot. By the way, during work, it may happen that the foot kicks the clamp cover 10. In such a case, even if the engagement between the engaging hook portion 8 and the engaging receiving portion 9 may be disengaged due to the impact, in the case of the clamp cover 10, the clamp cover 10 is opened and dropped due to the above-mentioned reason. There is no fear.

[0011]

The clamp cover of the present invention is as described above, and causes a worker's leg or the like to be injured by hitting a bolt or the like for fastening the clamp fitting, or causes the worker's clothes to catch on it, causing a fall. It is of course possible to eliminate the danger of becoming sick and protect the safety of the worker, but there is no risk of the worker falling off even if a slight shock is applied, such as when he is kicked with his feet during the work, You can trust.
