DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement in a clamp for holding a long rod-like body such as a hose or a pipe.

[0002]

2. Description of the Related Art As a conventional clamp of this type, for example,
Japanese Unexamined Patent Application Publication No. 10-30750 discloses one. Although not specifically shown, the conventional clamp includes a block-shaped base fixed to the panel side and a pair of holders standing upright in a U-shape in which the front ends facing the upper surface of the base are separated from each other. A holding piece, and a lid piece that is connected to the side surface of the base via a thin hinge part so as to be openable and closable, and a locking projection is provided on the outer surface of the distal end portion of the holding piece on the side where the lid piece is not provided. Then, a locking claw portion for locking to the locking projection is formed on the inner surface of the distal end portion of the lid piece.

At the time of actual use, a state in which the block-shaped base is fixed to the panel side via fixing means is obtained in advance, and a rod-shaped body is inserted into the inside from the tip openings of the pair of holding pieces. After that, when the cover piece is rotated around the thin hinge portion as a rotation fulcrum so as to wind each holding piece, the locking claw portion formed on the cover piece side has a locking projection formed on the holding piece side. , So that the tip openings of the pair of holding pieces are completely closed, so that the rod-shaped body is held inside the pair of holding pieces without coming off.

[0004]

Therefore, in the conventional clamp, the presence of the lid makes it possible to securely hold the rod-like body inside the pair of holding pieces. However, since the guide portions are not provided at all at the tip portions of the pair of holding pieces, when the rod-shaped body is inserted into the inside from the tip openings of the holding pieces, insertion guideability is lacking. I hate it.

[0005]

SUMMARY OF THE INVENTION The present invention has been developed in order to effectively solve the problem of the conventional clamp, and the invention according to claim 1 includes a base fixed to the mounting member, U whose front ends facing the upper surface of the base are separated from each other

Is equal to the distance from the rotation center of the lid piece to the base of the other holding piece.

According to a third aspect of the present invention, on the premise of the first and second aspects, an independent leg is erected on the upper surface of the base body at a predetermined distance from the other holding piece, and the leg is provided. A locking projection is formed on the inner surface of the tip of the piece, and a locking claw for locking to the locking projection is formed on the outer surface of the tip of the lid. The center of curvature of the inner surface of the leg is rotated by the lid. The main configuration was adopted.

According to a fourth aspect of the present invention, based on the third aspect, the lid piece includes a base end portion, an intermediate portion, and a front end portion which follow the thin hinge portion, and each one side edge of the base end portion and the front end portion. And a wall that engages with the corresponding side surface of the pair of holding pieces, and a wall that engages with the corresponding side surface of the tip portion of the lid piece is formed on one side edge of the leg piece. .

Therefore, in the first aspect of the present invention,
When inserting a rod-shaped body between a pair of holding pieces, the tip end of each holding piece is thick and a tapered surface is formed inside it, so a relatively long tapered surface is used as a guide, The body can be inserted very smoothly. In the invention according to claim 2, the inner surface curvature of the lid piece and the outer surface curvature of the other holding piece are the same, and the radius of curvature is from the rotation center of the lid piece to the base of the other holding piece. When the cover piece is rotated, the cover piece can be easily overlapped on the outer surface side of the other holding piece with only one rotation operation.

According to the third aspect of the present invention, the rigidity of the leg pieces can be freely adjusted irrespective of the holding force of the rod-shaped body, since the leg pieces having the locking projections are independently erected. The locking claw on the lid can be automatically locked to the locking protrusion on the leg only by rotating the lid, and the locking projection can be locked by an external force other than the turning direction. The locked state of the claw is not released. According to the fourth aspect of the present invention, the wall on the side of the lid and the wall on the side of the leg act from directions opposite to each other, so that the lateral displacement of the lid can be effectively prevented. There is no fear that the piece will come off the leg piece or the holding piece.

H is elastically locked to the bracket B so as to be fixed to the bracket B. However, the fixing means for the bracket B is not limited to this, and an elastically deformable anchor-shaped locking leg is provided. And so on.

In order to elastically hold a rod-like body such as a hose inside the pair of holding pieces 2 and 3, small projections 8 are provided at regular intervals on each inner surface and the upper surface of the base 1. The holding piece 2 on which the lid piece 4 is continuously provided is formed.
For this purpose, a locking projection 9 for locking a locking claw 14 on the lid piece 4 side, which will be described later, is formed on the outer surface of the distal end portion, and one of the holding projections 9 is held by utilizing the presence of the locking projection 9. The tip of the piece 2 is set to be thicker toward the leading edge, and the tapered surface 10 for guiding the rod-like body is positively provided inside the piece 2.
One side surface of the locking projection 9 is cut out 11.

Conversely, for the other holding piece 3 to which the lid piece 4 is not continuously provided, the thickness of the holding piece 3 is made thicker toward the tip edge by the thickness itself. Similarly, the tapered surface 12 for guiding the rod-like body is positively provided inside the portion. In addition to this, the outer surface curvature and the inner surface curvature of the cover piece 4 are the same, and the radius of curvature is The distance between the center of rotation of the cover piece 4 (the center of the thin hinge portion 5) and the base of the other holding piece 3 is set to be equal.
A part of one side surface of the other holding piece 3 is cut out 13 like the above-described locking projection 9 of the one holding piece 2.

The cover piece 4 is composed of a base portion 4A, an intermediate portion 4B, and a tip portion 4C continuing from the thin hinge portion 5. With respect to the base portion 4A, the above-mentioned one side is attached to the inner surface near the thin hinge portion 5. A locking claw portion 14 for locking to the locking projection 9 of the holding piece 2 is formed, and a notch 11 of the locking projection 9 is formed on one side surface thereof.
Is formed on the inner surface of the intermediate portion 4B, and a protruding ridge 22 is formed on the inner surface in a state of being depressed one step, and on the outer surface of the tip portion 4C, A locking claw 16 for locking to the locking projection 20 is formed, a notch 17 is formed on one side of the locking claw 16, and an operation lever is provided at a predetermined distance from the locking claw 16. 18 are integrally protruded. Also, a wall portion 19 that engages with the notch 13 of the other holding piece 3 may be formed on one side surface of the distal end portion 4C.

Leg pieces 6 juxtaposed on the outer periphery of the other holding piece 3
Is formed on the inner surface of the distal end portion thereof with a locking projection 20 for locking the locking claw portion 16 formed on the distal end portion 4C side of the lid piece 4, and is locked on one side of the locking projection 20. A wall portion 21 that engages with the notch 17 of the claw piece 16, and a shape that is curved so that the center of curvature of the inner surface of the leg piece 6 becomes the rotation center of the lid piece 4. I do.

Therefore, when holding a rod-like body such as a hose using such a clamp, first, the bracket B is inserted into the base 1 with the lid piece 4 kept in the open state.
As shown in FIG. 5, a check pawl 7 is provided in the mounting hole H of the bracket B.
Are elastically locked, whereby the base 1 of the clamp is fixed to the bracket B side.

Then, this time, the rod-shaped body S is inserted between the pair of holding pieces 2.3. At the time of this insertion, as described above, the tip of each holding piece 2.3 is inserted. As shown in FIG. 6, the rod-shaped member S is inserted very smoothly by using the relatively long left and right tapered surfaces 10 and 12 as guides. It is possible to do.

After the rod-shaped member S has been inserted between the pair of holding pieces 2 and 3, the operating lever 18 described above is used to
When the cover piece 4 is rotated around the thin hinge portion 5 as a rotation fulcrum so as to wind the holding pieces 2 and 3, the locking claw 16 on the distal end portion 4 </ b> C side of the cover piece 4 engages with the locking projection of the leg piece 6. 20 and at the same time, the locking claw portion 14 on the base end portion 4A side of the lid piece 4 is locked to the locking projection 9 of one of the holding pieces 2 so that the pair of holding pieces 2 Since the distal end opening is completely closed and locked, as shown in FIG.
It is held without falling off inside of 3. Moreover, in this holding state, the intermediate portion 4B of the leg piece 6 faces the opening of the tip of the pair of holding pieces 2 and 3, and the ridge 22 is brought into contact with the rod S from above. Thus, a stable holding state of the rod-shaped body S can be obtained.

When the cover piece 4 is rotated, the inner surface curvature is the same as the outer surface curvature of the other holding piece 3 and the radius of curvature is different from the rotation center of the cover piece 4 to the other. Because the setting is made to be equal to the distance of the base of the holding piece 3, the lid piece 4 can be easily overlapped on the outer surface of the holding piece 3 with the other by only one rotation operation. And
It is possible to automatically lock the locking claw portion 16 of the tip portion 4C of the lid piece 4 to the locking projection 20 of the leg piece 6. Moreover,
Since the inner surface of the leg piece 6 is positively provided with a curved shape such that the center of curvature thereof becomes the rotation center of the lid piece 4, the locking claw 16 is locked to the locking projection 20. In conjunction with this, there is no fear that the cover piece 4 comes off from the leg piece 6 or the holding pieces 2.3 side. In addition, the fact that the leg piece 6 is erected independently of the pair of holding pieces 2 and 3 allows the rigidity of the rod body S to be freely adjusted irrespective of the holding force of the rod-shaped body S. Is also improved.

Further, in a state in which the lid piece 4 is wound around the holding pieces 2 and 3 and locked by polymerization, the base end portion 4 of the lid piece 4
Notch 1 of locking projection 9 of one holding piece 2 on wall A on the A side
1 and the wall 19 of the distal end portion 4C engages with the notch 13 of the other holding piece 3 to prevent lateral displacement of the lid piece 4 in one direction, and at the same time to the leg piece 6 side. Is engaged with the notch 17 of the locking claw 16 of the tip portion 4C of the lid piece 4 to prevent lateral displacement of the lid piece 4 in the other direction. Prevent the lateral displacement of the piece 4,
As a result, a secure lock state can be ensured.

[0022]

As described above, according to the present invention, according to the first aspect of the present invention, when a rod is inserted between a pair of holding pieces, the tip of each holding piece has a large thickness. Since the tapered surface is formed inside as a wall, the rod-shaped body can be very smoothly inserted by using the relatively long tapered surface as a guide. According to claim 2, the inner surface curvature of the lid piece and the outer curvature of the other holding piece are the same, and the radius of curvature is equal to the distance from the rotation center of the lid piece to the base of the other holding piece. When the lid piece is rotated, the lid piece can be easily overlapped on the outer surface side of the other holding piece with only one rotation operation.

According to the third aspect of the present invention, the rigidity of the leg can be freely adjusted irrespective of the holding force of the rod-shaped member because the leg having the locking projection is independently erected. The locking claw on one side of the lid can be automatically locked to the locking protrusion on the side of the leg only by the turning operation of the one side, and the engagement of the locking claw with the locking protrusion by external force other than the rotation direction. The stop state is not released. According to the fourth aspect of the present invention, the wall on the side of the lid and the wall on the side of the leg act from directions opposite to each other to effectively prevent lateral displacement of the lid. There is no fear of falling off from one side or holding one.
