[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a clamp used for holding pipes (for example, pipes for water, air, oil, fuel, etc.) of a vehicle engine in a fixed position.

[0002]

2. Description of the Related Art As shown in Japanese Unexamined Patent Publication No. 8-28756 or FIG. 4, conventionally, a clamp 1 of this type is composed of a pair of upper and lower clamp halves 3 having the same shape. It is composed of a block-shaped hard elastic body 5 made of hard rubber or synthetic resin, and a metal flat plate-shaped covering body 7 attached to the outer periphery of the hard elastic body 5, and the hard elastic body 5 and the covering body. Bolt holes 11 and 13 through which the bolt 9 is inserted through 7 are provided in the respective central portions.

Then, the mating surface 15 of the hard elastic body 5 is formed.
Has a semi-circular recess 17 for holding a pipe (not shown). The pipe is sandwiched between these recesses 17 to align the clamp halves 3, and the bolt holes 11, 13
Mount the clamp 1 with the bolt 9 inserted into the metal stay 1
After fixing to No. 9, the stay 19 was fixed to the body of the engine or the like and the pipe was attached at a predetermined position.

Further, FIG. 5 shows a clamp 23 using a cover 21 having both ends bent to the sides of the hard elastic body 5 instead of the flat cover 7, and the cover 21 also has the bolt 9 attached thereto. A bolt hole 25 for insertion is formed in the central portion. And
Similar to the clamp 1, the recess 17 provided in the hard elastic body 5
Piping is sandwiched between the clamp halves 27, and the clamp 23 is fixed to the stay 19 by the bolt 9 inserted into the bolt holes 25 and 11, and then the stay 19 is fixed to the engine body or the like. Was mounted in place.

However, since the clamps 1 and 23 have a large number of parts and the alignment between the bolt hole 29 provided in the stay 19 and the bolt 9 through which the clamps 1 and 23 are inserted is troublesome, workability is improved. There was a fault that it was bad. Therefore, in recent years, as shown in FIGS. 6 and 7, the hard elastic body 5 is directly attached to one end of the stay 19 to form the clamp half body 31, and the clamp half body 31 is provided with the clamp 1 described above. Clamps 33 and 35 obtained by bolting the upper clamp halves 3 and 27 of the clamps 23 and 23 are widely used.

[0006]

However, in the clamp 33 described above, there is no means for preventing lateral deformation or distortion of the hard elastic body 5 of the clamp halves 3 and 31, and FIG. Even in the illustrated clamp 35, there is no means for preventing lateral deformation or distortion of the hard elastic body 5 of the clamp half 33, so that if the bolt 9 is firmly tightened, the clamp half body 33 shown in FIGS.
It has been pointed out that the hard elastic body 5 is largely distorted and deformed laterally as shown in (3), and as a result, the tightening on the pipe is loosened during long-term use.

The present invention has been devised in view of such circumstances, and is for a vehicle in which deformation and distortion of a hard elastic body made of hard rubber or synthetic resin are prevented to maintain a tightening force for pipes. It is intended to provide a clamp for engine piping.

[0008]

In order to achieve such an object, the invention according to claim 1 is such that a block-shaped hard member made of hard rubber or synthetic resin is provided on one end side of a stay fixed to a body of an engine or the like. Fold along both sides of the lower elastic body and the cover body to which the block-shaped hard elastic body made of the same material as the hard elastic body is attached. It consists of an upper clamp half with a bent piece, a semicircular recess for holding pipes is formed on the mating surfaces of both hard elastic bodies, and a bolt hole for inserting a bolt is formed in both clamp half. In the formed vehicle engine piping clamp, a bent piece facing one bent piece provided on the cover of the upper clamp half at one end side end of the stay of the lower clamp half. Along with one side of the hard elastic body, The other bent piece of the clamp halves,
It is characterized in that it is extended in the stay direction along the other side of the hard elastic body of the lower clamp half body.

(Operation) In order to hold the pipes on the engine body or the like by using the clamp according to the first aspect, the pipes are sandwiched between the recesses of both hard elastic bodies, and the clamp halves are aligned with each other, and After bolting these, the stay may be fixed to the body of the engine or the like. Thus, when both clamp halves are bolted in this way, the hard elastic body tries to deform to both sides, but one bent piece provided in the cover body is one of the hard elastic body attached to the cover body. The other bent piece prevents deformation of the other side of the hard elastic body of both clamp halves while preventing deformation of the side portion, and the bent piece provided on the stay of the lower clamp half body. However, it prevents lateral deformation of the hard elastic body of the lower clamp half body.

When the hard elastic body is compressed by tightening the bolts too tightly, the bending piece provided on the cover and the bending piece provided on the stay come into contact with each other, and the other bend of the cover is bent. The tips of the pieces come into contact with the stays to prevent distortion of the hard elastic body.
