Abstract

PROBLEM TO BE SOLVED: To use a simplified clamp, used for nipping a plurality of woods to adhere woods, for a member fixed on a wall surface and a ceiling surface. SOLUTION: Fastening arms 3 and 4 are slidably inserted in a square columnar main lever 1 and fixing bolt body 5 is arranged at the fastening arm 4 on the opposite to the fixed arm. A press bolt body 6 consisting of a thread shaft part 61 threadedly mounted on the fixing arm 2, a grasping part 62 rotationally operating the threaded shaft part 61, and a universal joint part 63 to intercouple the threaded shaft part 61 and the grasping part 62 is mounted on the fixed arm 2 arranged in a branching state on the one end side of the main lever 1.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a simple clamp called a fastening grouper, grouper, gluing clamp or the like.

[0002]

2. Description of the Related Art In a simple clamp, a clamping arm is slidably fitted into a prismatic main rod, and a fixed arm is provided at one end of the main rod in a direction in which the clamping arm protrudes. Attach the pressure bolt body that presses the arm, and on the tightening arm opposite the fixed arm,
It is provided with a fixing bolt body for fixing to a main rod (Japanese Utility Model Publication No. 61-42776). An object to be fastened is clamped between a fastening arm close to the fixed arm and a fastening arm provided with the fixing bolt. Is fixed with a fixing bolt body, and the other tightening arm is pressed by a pressing bolt to strongly clamp the object to be tightened.

[0003]

The above-mentioned simple clamp is used for cutting the overlapped wood, or for strongly pressing and holding the bonding surface until the adhesive solidifies when bonding is required. However, in the conventional simple clamp, since the pressing bolt body is continuously integrated with the screw shaft and the operation knob, for example, in the case where another member is adhered to the slender provided on the wall surface, the operation is difficult. The knob is located closer to the wall surface than the main rod, and the operation rotation axis is parallel to the wall surface, so that the operation is very difficult. The same can be said of the case where the present invention is used for a member attached to a ceiling surface or a floor surface.

Accordingly, the present invention proposes a novel clamp which can easily perform a pressing operation even when a member attached to a wall or the like and another member are clamped together.

[0005]

SUMMARY OF THE INVENTION A simple clamp according to the present invention is a simple clamp comprising a prismatic main rod, a tightening arm, a fixed arm, a pressing bolt body and a fixing bolt body. It is characterized in that the body is formed of a screw shaft portion screwed on the fixed arm, a knob for rotating the screw shaft portion, and a universal joint for connecting the screw shaft portion and the knob portion.

Therefore, even when the operation knob is used for holding the wall-mounting member and other members, the operation knob can be bent in the direction in which the operation knob is slightly raised from the wall side, and the rotation operation can be performed, and the pressing operation can be easily performed.

[0007]

Next, an embodiment of the present invention will be described. The simple clamp shown in the embodiment includes a main rod 1,
It is composed of a fixed arm 2, fastening arms 3 and 4, a fixed bolt body 5, and a pressing bolt body 6.

The main rod 1 has a prismatic shape and is provided with a fixing concave portion 11 at an appropriate position, a fixing arm 2 protruding in a branch shape at one end, and a fastening arm 3, 4 attached thereto.

The fastening arms 3 and 4 are provided with a mounting hole corresponding to the prism shape of the main rod 1, and the main rod 1 is inserted through the mounting hole.
The fixing arm 2 is slidable in a protruding state on the protruding side thereof. Further, a fixing bolt body 5 for fixing to the main rod 1 is provided on the tightening arm 4 located on the side opposite to the fixing arm 2.

In particular, the present invention is characterized by a pressing bolt body 6 provided on the fixed arm 2. The pressing bolt body 6 includes a screw shaft 61 screwed on the fixed arm 2 in an axial direction parallel to the main rod 1. A knob 62 for rotating the screw shaft 61 and a universal joint 63 for connecting the screw shaft 61 and the knob 62.

As shown in FIG. 2, a member B fixed to a wall A and a member C which needs to be held together with the member B are clamped by clamping arms 3, 4. In particular, the fastening arm 3 on the side of the fixed arm 2 is positioned near the fixed arm 2, and the fastening arm 4 is fixed by operating the fixing bolt body 5 of the other fastening arm 4 correspondingly. Further, when the operation knob 62 is bent so as to rise from the wall surface A and the operation knob 62 is rotated, the clamping arm 3 is strongly pressed by the pressing bolt body 6, so that the clamped objects B and C are strongly clamped. Will be.

[0012]

As described above, the present invention employs a universal clamp in a simple clamp, particularly in the operation knob portion of the pressing bolt body, and does not hinder the clamping operation even when clamping together with a member fixed to a wall or the like. The range of use of the simple clamp is expanded without any.
