Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a clamp device for piping / wiring components, and more particularly to a clamp device suitable for fixing pipe / wiring components arranged across an edge portion of a plate member.

[0002]

[Prior Art]

 For example, in vehicles, piping / wiring components are arranged inside body frame members such as side members and cross members in order to effectively use space and protect piping / wiring components. When the piping / wiring parts are extended upward from the vehicle body frame, in order to prevent the piping / wiring parts from being damaged due to interference with the edge portions of the side members and cross members, conventionally, a fixing structure as shown in FIG. 3 is used. I was trying.

For example, a resin clip in which pipings 2 for air and oil and wirings 3 such as electric wirings are arranged along the inside of the side member 1 having a U-shaped cross section, and these are fixed in place inside the side member 1. Hold at 4 mag. At the portion where the pipe 2 and the wiring 3 are extended above the side member 1, the pipe 2 and the wiring 3 are bent from the inside of the side member 1 to the outside along the wall surface of the side member so as to straddle the edge portion 1a, and the side member 1 The pipe 2 and the wiring 3 are held by a resin clip 5 or the like fixed to the upper surface of the bar 1. In this case, a gap of about 15 to 20 mm is secured between the edge portion 1a and the pipe 2 and the wiring 3 so that the pipe 2 and the wiring 3 do not come into contact with the edge portion 1a to prevent the interference therebetween. I am trying.

[0004]

[Problems to be solved by the device]

 However, in the conventional fixing structure using the resin clip 5 as shown in FIG. 3, when a relative movement occurs between the vehicle body frame side and an upper portion thereof while the vehicle is traveling, the pipe 2 and the wiring 3 are axially moved. There is a possibility that it may move and come into contact with the edge portion 1a. As a piping / wiring component clamping device, there is one disclosed in, for example, Japanese Utility Model Laid-Open No. 1-169606.

The present invention has been made in view of the above circumstances, and it is an object of the present invention to provide a clamp device capable of reliably preventing interference with an edge portion when a pipe / wiring component is arranged across the edge portion. And

[0006]

[Means for Solving the Problems]

 Therefore, the present invention is a clamp device for holding piping / wiring components arranged across the edge portion of a plate member, and has a substantially U-shape so as to be engageable with the edge portion of the plate member. The engaging portion formed by bending and the mounting hole formed on the plate member side are engaged with the plate hole by the elastic restoring force of a plurality of claw members provided in the peripheral portion of the front end in a penetrating state. A fixing portion for fixing and a holding portion which is provided at the engaging portion portion parallel to the edge portion of the plate member and elastically holds the pipe / wiring component are configured.

[0007]

[Action]

 According to this configuration, the engaging portion is engaged with the edge portion of the plate member, the fixing portion is penetrated into the mounting hole of the plate member to fix the clamp device to the plate member, and then the holding portion of the clamp device is connected to the pipe / pipe. Install wiring parts. As a result, the piping / wiring parts are securely held by the clamp device by the elastic holding force of the holding part, and the clamp device is firmly fixed to the plate member by the engaging part and the fixing part, and further, the edge part Since the engaging part is interposed between the piping / wiring parts, interference between the piping / wiring parts and the edge part can be reliably prevented, and the parts can be firmly fixed.

【Example】

 An embodiment of the present invention will be described below with reference to FIGS. The same elements as those of the related art will be designated by the same reference numerals and the description thereof will be omitted. In the figure, the clamp device 10 of the present embodiment is formed of, for example, a synthetic resin, and has a substantially flat shape that can be engaged with one end of a flat plate member, for example, an edge portion 1a of a side member 1 as a plate member. It has an engaging portion 11 that is bent in a letter shape, and has a columnar shape and a tip peripheral edge projecting in the same direction as the bending direction of the engaging portion 11 near the end opposite to the engaging portion 11. A fixed portion 13 having, for example, four claw portions 12 is provided at equal intervals. The claw portion 12 is elastically deformable and has a taper surface 12a that is tapered on the outer surface side. The claw portion 12 is elastically restored to the mounting hole 6 when the fixing portion 13 penetrates the mounting hole 6 formed in the side member 1. The clamp device 10 is locked to the side member 1. Further, a holding portion 14 having a substantially cylindrical shape and a part of the periphery thereof being cut out is formed at a portion of the engaging portion 11 parallel to the edge portion 1a of the side member 1. The holding portion 14 is formed such that the opening portion can be elastically expanded, the opening width of the opening portion is narrower than the diameter of the pipe 2 and the wiring 3 to be held, and the tip end side is an outwardly V-shaped. It is formed by expanding.

Next, the operation will be described. To attach the clamp device 10 to the side member 1, first, the engaging portion 11 is engaged with the edge portion 1a of the side member 1 as shown in FIG. Next, the fixing portion 13 is pushed in until its tip penetrates the mounting hole 6 of the side member 1. By this pushing-in operation, the claw portion 12 elastically deforms and contracts, and when the fixing portion 13 enters the mounting hole 6 and penetrates, it elastically returns and expands, and engages with the peripheral portion of the mounting hole 6. As a result, the clamp device 10 is fixed to the side member 1. After fixing the clamp device 10 to the side member 1, the pipe 2 and the wiring 3 extended upward from the inside of the side member 1 so as to straddle the edge portion 1a are attached and fixed to the holding portion 14. When attaching the pipe 2 and the wiring 3 to the holding portion 14, the pipe 2 and the wiring 3 are attached by being pushed in from the open portion of the holding portion 14. In this case, the open portion elastically expands by the pressing force, and when the pipe 2 and the wiring 3 enter the holding portion 14, the open portion elastically returns and narrows to the original state to elastically hold the pipe 2 and the wiring 3.

According to such a clamp device 10, the clamp device 10 is firmly fixed to the side member 1 by the engaging portion 11 and the claw portion 12 of the fixing portion 13, and the pipe 2 and the wiring 3 are held by the holding portion 14. It is firmly fixed and held. In addition, since the engaging portion 11 is interposed between the pipe 2 and the wiring 3 and the edge portion 1a of the side member 1, even if the pipe 2 and the wiring 3 move to some extent due to shaking of the vehicle when the vehicle is traveling, There is no concern that the pipe 2 and the wiring 3 contact the edge portion 1a. Therefore, it is possible to reliably prevent damage to the pipe 2 and the wiring 3 due to interference with the edge portion 1a.

The object to which the clamp device 10 is applied is not limited to the side member as in the present embodiment, and in the case of piping / wiring so as to straddle the edge portion of the plate member, However, it goes without saying that it can be applied.

[0012]

[Effect of the device]

 As described above, according to the present invention, it is possible to reliably prevent the interference between the pipe / wiring component arranged so as to straddle the edge portion of the plate member and the edge portion. Damage accidents can be reduced and the service life of these parts can be extended.
