Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a clamp device for a vehicle such as a truck.

(Prior Art) In a conventional truck having a tilt-type cab, various electric devices, switches and instruments provided in the cab, a steering device, a brake control device, and a cab are provided outside the cab. An electric harness in which a large number of electric wires that connect to an engine, a transmission, a brake device, a lighting device, and the like are bundled, and a bundle of pipes or tubes such as a pipe for air piping penetrates the floor of the cab and a body member such as a chassis frame. The electric harness and the bundle of pipes are arranged so that the tilt movement of the cab can be freely permitted, and when the cab is elastically suspended with respect to the chassis frame, In order to allow relative displacement of the cab that occurs inside the chassis frame,
They are clamped on the cab side and the chassis frame side, respectively.

Now, with reference to FIGS. 3 and 4, a typical configuration of a conventional clamp device for locking a conventional electric harness and a bundle of pipes with a vehicle body member such as a cab and a chassis frame will be described. Usually, a strip-shaped or strip-shaped steel plate having a thickness of about 1 mm is bent to form an annular portion 12 into which a bundle H of an electric harness or pipes is inserted, and terminal portions 14a and 14b at both ends are overlapped with each other. A clamp fixed to a vehicle body member 18 such as a frame of a cab or a chassis frame by bolts or screws 16 is generally shown, and an electric harness or a pipe bundle H is elastically attached to the inner peripheral surface of the annular portion 12. At the same time as holding and positioning, a rubber cushion 20 for preventing damage is baked and fixed.

In the above-described conventional clamp device, when the cab is tilted and when the cab and the chassis frame are displaced relative to each other due to the operation of the suspension system during traveling, a large bending and twisting force is applied to the electric harness or the pipes. Body H
Transmitted to the clamp 10. For this reason, the clamp 10 itself made of thin steel plate undergoes torsional deformation, or rotates around the mounting bolt or the screw 16, and the position of the electric harness or the pipes converging body H deviates from the normal position, and the peripheral position There is a risk that they may interfere with other members and may be worn away at an early stage, causing an electrical failure such as a short circuit or a problem such as leakage of compressed air.

(Problems to be solved by the invention) In order to solve the above-mentioned problems of the conventional clamp device, the clamp 10 is manufactured from a steel plate having a sufficient thickness to increase its own strength, and the clamp 10 is mounted on the vehicle body. A method of immediately preventing the rotation by using two bolts or screws tightening the member is immediately recalled. However, when the clamp 10 itself is made of a thick steel plate, when the bundle H of an electric harness or pipes is inserted, the terminal There is a problem that the workability is poor because the force required to open the parts 14a and 14b is large, and the clamp 10 does not exert a large force, and therefore the clamp body 10 is made of a thin steel plate and uses only one bolt or screw. Since the commonality of the parts is lost with many other body part clamps which have no problem even if they are locked to the member, there is a disadvantage that the price of the clamp itself becomes extremely high.

The present invention has been made in view of the above circumstances, and when used in a portion where a large bending and / or twisting force acts on a clamp from an object to be gripped such as the electric harness or pipes converging body, An object of the present invention is to provide an inexpensive clamp device capable of holding a body to be grasped at a correct position and effectively preventing damage thereof without causing deformation or rotation of the clamp itself. To do.

(Means for Solving the Problems) In order to achieve the above-mentioned object, the present invention folds a strip-shaped thin metal plate to form an annular part for inserting wires and pipes in the central part, and stacks end parts at both ends. Through a clamp that is also fixed to the vehicle body member with a first bolt or screw, and a base portion that is fixed to the vehicle body member with a second bolt or screw and a step portion formed along the edge of the terminal portion. A reinforcing member having an extension part connected to the base part and abutted to the outer end part of the terminal part and the annular part and fastened together with the terminal part together with the end part by the first bolt or screw. The present invention proposes a vehicle clamp device characterized by the above.

(Operation) According to the present invention, by attaching the reinforcing member to the ordinary clamp, the clamp itself is prevented from being deformed, and the clamp is prevented from rotating around the mounting bolt or screw.

(Embodiment) An embodiment of the present invention will be specifically described below with reference to FIGS. 1 and 2. The clamp itself, indicated generally by the numeral 10 in the figures, is essentially equivalent to the previous one shown in FIGS. 3 and 4, the ends 14a and 14b of which have first bolts or screws. It is fastened to the body member 18 only by 16.

On the outside of the clamp 10, a relatively large plate thickness, for example 2 m
A reinforcing member 22 manufactured by press-forming a steel plate having a thickness of m is provided. The reinforcing member 22 has a base portion 22a which is tightened to the vehicle body member 18 by a second bolt or screw 24 and a step portion or a barbed portion 22b formed adjacent to the end edges 14c of the terminal portions 14a and 14b. The extension portion 22 connected to the base portion 22a through the
The extension 22c includes a flat portion that abuts the outside of the terminal portion 14a and an arc-shaped portion that abuts the outside of the annular portion 12 of the clamp, and the flat portion is the terminal portion 14a. , And 14b together with the first bolt or screw 16 and fixed to the body member 18 together.

According to the above configuration, the grasped object H such as the electric harness or the pipes converging body held by the clamp 10 bends due to the tilt movement of the cab and the like, and the clamp 10 greatly bends (or ) When a twisting force is applied, the clamp annular portion 12 and the end portions 14a and 14b are reinforced by the extension portion 22c of the thick reinforcing member 22, so that the deformation of the clamp 10 itself is effectively prevented. . Further, the end edges 14c of the terminal portions 14a and 14b of the clamp 10 are locked by the step portion 22b of the reinforcing member, and the reinforcing member 22 is prevented from rotating by the first and second bolts or screws 16 and 24. By being fixed to the vehicle body member 18, the rotational displacement of the clamp 10 is prohibited. Therefore, it is possible to effectively prevent the object to be grasped H from being damaged or burned due to interference with other adjacent parts or vehicle body members.

The clamp 10 is remarkably inexpensive because it is possible to use the same parts as the clamps of other parts that do not particularly require strength, and the reinforcing member 22 is a simple press-molded product and requires rubber baking or the like. Since it can be manufactured at a low cost without using any of the clamps, there is an advantage that the entire clamp device can be provided at a low cost, as compared with the case where a small amount of a special clamp having high strength is manufactured.

It should be noted that the clamp device according to the present invention is not limited to the clamp of an electric harness or a pipe assembly which is arranged between the cab of the truck having the tilt-type cab described above and the adjacent chassis frame. However, the present invention can be widely applied to a clamp device to which a large bending and / or twisting force acts.

(Effects of the Invention) As described above, the vehicle clamp device according to the present invention bends a strip-shaped thin metal plate to form an annular portion into which a wire or pipe is inserted in the central portion, and the terminal portions at both ends are connected. A clamp, which is superposed and fixed to the vehicle body member by the first bolt or screw, and a base portion, which is fixed to the vehicle body member by the second bolt or screw, and a step portion formed along the edge of the terminal portion are provided. A reinforcing member having an extension part connected to the base part through the end part and abutted on the outer side of the annular part and fastened together with the end part together with the terminal part by the first bolt or screw. It is characterized in that it is possible to provide at low cost a clamp device capable of stably holding an object to be grasped such as an electric harness, which is practically useful.
