Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pair of clamp members for holding a long body, a pair of locking portions capable of locking one end of the pair of clamp members, and a mounting member for mounting on a frame side. The present invention relates to a long body fixing device including a main body member provided with a fixing portion, and a long body holding / fixing method for holding the long body and fixing it to the skeleton side.

[0002]

2. Description of the Related Art Conventionally, as this kind of long body fixing device, a pair of left and right locking portions provided on a main body member for locking a pair of clamp members to the main body member side is fixed. Some products have a positioning margin in the left-right direction. In addition, as this kind of long body holding and fixing method,
Surrounding the elongated body with the main body member and the pair of clamp members using the conventional elongated body fixing device,
The ends of each of the clamp members on the side not engaged with the elongated body fixing tool are fastened with a fastening member, and at least the inner surfaces of the pair of clamp members are brought into close contact with the surface of the elongated body, thereby forming the elongated body. There was a method of holding and fixing a long body to be held.

[0003]

However, in the above-described conventional method for holding and fixing a long body using the long body fixing tool,
For example, in order to support and fix the elongate body in the vertical direction, the elongate body is strongly in close contact with the surface of the elongate body, and the elongate body resists the force of falling down by its own weight. There is a problem that the same portion is strongly held for a long period of time depending on the material of the surface of the elongate body, resulting in deterioration of wear. Further, there is a danger that the pinching force is weakened due to the wear deterioration of the surface of the elongated body, and the elongated body falls downward. SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned problems, and to provide a long body fixing tool and a long body fixing member capable of reliably supporting and fixing a long body regardless of the supporting direction of the long body and the material and properties of the surface of the long body. Another object of the present invention is to provide a method for holding and fixing a scale.

[0004]

A first feature of the present invention relating to a long body fixing device for achieving this object is as described in claim 1 of the claims. A pair of clamp members for holding the body, and a main body member for mounting the pair of clamp members, wherein the main body member is capable of slidably locking one end side of each of the clamp members. It is characterized in that it has a non-parallel locking groove and a fixing part for attachment to the skeleton side.

[0005] The second characteristic configuration is, as described in claim 2 of the claims section, in addition to the above-mentioned first characteristic configuration, each of the locking grooves is formed in a flat plate portion of the main body member. The point is that it is a provided through groove.

According to a third feature of the present invention, as described in claim 3 of the claims, in addition to the above-described second feature, one end of each of the locking grooves in the longitudinal direction is the same as that of the second feature. An opening extending from the one end to the edge of the flat plate portion so that the clamp member can be inserted into the locking groove is formed in the edge.

A fourth feature of the present invention relating to a method for holding and fixing a long body for achieving this object is as described in claim 4 of the claims. Alternatively, the elongate body is surrounded by the main body member of the elongate body fixing device of the third characteristic configuration and the three members of the pair of clamp members, and the ends of the clamp members on the side not engaged with the main body member are separated from each other. When an acting force acts on the elongated body along the longitudinal direction when the elongated body is clamped by the fastening member, the pair of locking groove portions are moved in a direction in which the acting force acts. Is that the main body member is attached to the skeleton side such that the distance between the main body members is reduced.

The operation and effect will be described below. According to the first characteristic configuration, the pair of clamp members, one end of which is slidably locked to each of the locking grooves and attached to the main body member side, hold a long body therebetween. In the state where the other ends are connected to each other, when sliding along the longitudinal direction of the elongated body, the distance between the clamp members changes, so that the clamping force on the elongated body also changes. For example, when supporting the elongate body in the vertical direction, the attractive force due to its own weight acts on the elongate body toward the lower side in the longitudinal direction, but the direction in which the interval between the clamp members is reduced is toward the lower side. If the main body member is fixed to the skeleton side so that the elongated member attempts to drop downward due to the attractive force, the clamp member slides in a direction in which the interval between the clamp members decreases, The clamping force of the clamp member on the elongated body is increased, and acts to prevent the elongated body from falling. As a result, any action force such as the above-mentioned attractive force acts on the elongated body in the longitudinal direction, and even if the elongated body attempts to move along the longitudinal direction, the clamping force is automatically increased with the movement. The clamping member first clamps the elongate body with the minimum necessary clamping force, and then the clamping force is automatically adjusted. Since the elongate body is securely supported and fixed, and the force for pressing the elongate body surface is not unnecessarily excessive, wear and deterioration of the elongate body surface are suppressed, and the elongate body has a longer life. Can be achieved. Furthermore,
When the elongate body is moved along the longitudinal direction in a direction in which the interval between the clamp members is widened, the clamp member slides in the same direction together with the elongate body, so that the interval is widened and the Since the holding force on the elongated body is reduced, the operation of removing the elongated body can be speeded up.

According to the second characteristic configuration, since each of the locking grooves for automatically adjusting the clamping force has a simple shape, the manufacturing cost can be reduced. Furthermore,
With a simple operation of inserting one end of each of the clamp members into each of the locking grooves and hooking it on the back side, each of the clamp members can be locked to each of the locking grooves, thereby impairing the workability of the mounting operation. Therefore, the clamping force of each of the clamp members can be automatically adjusted.

According to the third characteristic configuration, the operation of inserting one end of each of the clamp members into each of the locking grooves and hooking it on the back side is provided with one end of each of the clamp members on the flat plate portion. The insertion work can be further simplified by inserting it into each of the locking grooves from the opening, and the efficiency of the mounting work can be increased.

According to the fourth aspect, the elongated body is surrounded by the main body member and the pair of clamp members of the elongated body fixing device of the first, second or third aspect. In the long body holding and fixing method of holding the long body by fastening the ends of the clamp members on the side that is not locked to the main body member with a fastening member, the same effect as the first characteristic configuration is obtained. The effect can be expected.
