[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a clamp for holding a brake pipe or a fuel pipe (hereinafter, referred to as a tubular body) in an automobile, for example.

[Prior art]

2. Description of the Related Art Conventionally, there are clamps of this type which are used on the bottom of an automobile. For example, a clamp as shown in FIG. 5 is well known. As shown in FIG.
It is composed of two parts: a resin clamp body 40 for fitting and holding a plurality of tubular bodies, and a metal holding plate 41 for restricting the tubular bodies from falling off.
In use, first, the clamp body 40 is attached to the body. In this case, although not shown in the drawing, the attachment is performed by fixing means formed on the lower surface of the clamp body 40. Next, the tubular body is inserted and held in the holding groove 42 of the clamp body 40, and finally the pressing plate 41 is held.
With the tapping screw 43
The fastening operation of the tubular body is completed. However, the conventional clamp has the following problems to be solved.

[0003]

First, the operation of mounting the holding plate 41 is cumbersome. That is, the work of attaching the holding plate 41 is a screw tightening work while holding the plate 41, and the workability is not good. As a countermeasure, a one-touch type engaging means may be used instead of the tapping screw 43. For example, a bending claw which can be bent and deformed at both ends of the holding plate 41 is provided so as to elastically engage with the clamp body side. Then, the troublesome screw tightening work can be omitted. However, such a method lacks reliability when an external force acts on the tubular body in the pull-out direction.

[0004] Second, the tubular body may be detached from the clamp for repair work even after it is fixed, but in this case, it is not possible to obtain the initial tightening force even if it is screwed again. Therefore, there is a possibility that the tapping screw 43 may come off due to the vibration of the automobile, and the holding plate 41 may fall off, and even a situation in which the tubular body is finally detached is expected.

A third problem is that the number of parts and the number of steps are increased due to the screw tightening operation. The present invention has been developed in view of such circumstances, and an object of the present invention is to provide a clamp capable of securely holding a tubular body while reducing the number of parts and improving work efficiency. That is.

[0006]

According to the present invention, there is provided a clamp body having an opening formed with a holding groove in which a tubular body can be fitted along an axial direction, and The clamp body is provided with a fixing portion for fixing the clamp body to another member, while the holding plate is provided separately from the fixing portion in the clamp body. The holding groove is mounted rotatably in a plane parallel to the opening so that the opening of the holding groove can be opened and closed with respect to the rotation center provided in the holding plate, and the holding groove is closed at the end of the holding plate. A locking portion is formed to engage with the clamp body in a detented state at the position.

[0007]

As an example of mounting the tubular body, first, the clamp main body is fixed to another member by the fixing portion, and the holding plate is held at the position where the opening of the holding groove is opened, and about the center of rotation. Then, after fitting the tubular body into the holding groove of the clamp body, the holding plate is rotated to a position where the holding groove is closed. Then, the retaining plate engages with the clamp body and the entire retaining plate is prevented from rotating, whereby the retaining plate is held at the position where the opening of the holding groove is closed. Thus, even if the tubular body receives an external force in the pulling-out direction, the holding plate resists this and is securely held in the holding groove.

[0008]

1 to 3 show a first embodiment of the present invention, and FIG. 2 is an exploded perspective view of a clamp. As shown in the figure, the clamp C is composed of a clamp body 1 integrally formed of a synthetic resin material, and a metal (or resin) holding plate 2 having appropriate elasticity.

First, the holding plate 2 will be described.
A mounting hole 3 extends through the center of the holding plate 2. The mounting hole 3 is provided with a support projection 4 of the clamp body 1 described later.
In order to guide the support projection 4 into the mounting hole 3, the guide groove 6 extends from the side edge of the holding plate 2.
Is cut into the mounting hole 3. On the other hand, at both ends of the holding plate 2, locking portions K serving to prevent the entire holding plate 2 from rotating are formed. The locking portion K includes first and second locking pieces 8 and 9 formed with a U-shaped notch 7 at the center of both ends of the holding plate 2. The first locking piece 8 is the holding plate 2
The second locking piece 9 extends substantially the same length as the first locking piece 8 and then bends downward to have a bent portion 10. . As shown in FIG. 1 and FIG.
Are arranged in reverse, that is, point-symmetric with respect to the mounting hole 3.

Next, the clamp body 1 will be described. The clamp body 1 is formed in a rectangular parallelepiped shape having substantially the same length and width as the holding plate 2. Known fixing means for fixing are set. As a well-known fixing means, for example, when a stud bolt is erected on the floor side, a clamp body 1 is provided with a hole into which the stud bolt is inserted and a claw that can be engaged with the stud bolt, In the case where an opening is provided, there is a type including an elastically deformable member (for example, a member having an anchor shape) which is inserted into the opening in a retaining state.

On the other hand, in this embodiment, four rows of holding grooves 111 to 1 for holding the tubular body P in the clamp body 1 are provided.
14 are provided in parallel with the partition walls 121 to 123 interposed therebetween. Each of the holding grooves 111 to 114 is opened upward in the drawing to form insertion ports 131 to 134, and each of the grooves is tapered toward the holding grooves 111 to 114 for guiding the insertion into the holding grooves 111 to 114. It is formed in a pot shape. The width of the bottom surface of the insertion holes 131 to 134, that is, the opening width of the holding grooves 111 to 114 is formed slightly smaller than the outer diameter of the tubular body P.
21 and 122 (except those located at the center in the figure) and the right and left side walls 141 and 142 of the clamp body 1 are tubular bodies P
Is allowed to be deformed enough to allow the insertion of the.

Further, one of the partition walls located at the center 1
23 is formed to be thicker than the other two, and the mounting surface 15 for the holding plate 2 is formed on the upper surface. A support projection 4 is integrally provided upright at the center thereof, and serves as a rotation center of the holding plate 2 as described above. The support projection 4 includes a shaft portion 5 and a flange portion 16 formed on the top of the shaft portion 5. The flange portion 16 having a larger diameter than the mounting hole 3 protrudes from the mounting portion 3. It is designed to prevent a situation in which the player slips in the direction. The upper edges of the partition walls 121 to 123 and the upper edges of the left and right side walls 141 and 142 of the clamp body 1 are almost flush with each other.

Further, on the upper edges of the left and right side walls 141 and 142, there are formed rotation restricting portions S for engaging with the locking portions K of the holding plate 2 to prevent the plate 2 from rotating. The rotation restricting portion S is provided with a locking projection 17 in the center,
One side is a first rotation restricting portion 18 for the first locking piece 8 with the locking projection 17 as a boundary, and the other side is a second locking piece 9
The second rotation restricting portion 19 with respect to. Therefore, the positional relationship between the two regulating portions 18 and 19 is determined by the pressing plate 2.
Are arranged point-symmetrically in correspondence with the locking portions K. The rotation restricting portions 18 and 19 and the corresponding locking portions K are engaged with each other by rotating the holding plate 2 (the operation in the direction of the arrow shown in FIG. 1).
, The side facing the first locking piece 8 when the holding plate 2 is rotated in the direction of the arrow shown in FIG. 1 is an inclined surface 20, and the first locking piece 8 is locked. The projecting piece 17 can be overcome. Conversely, the locking projection 17
, That is, the side facing the first rotation restricting portion 18 is formed vertically. Thereby, rotation of the holding plate 2 in the direction opposite to the arrow shown in FIG. 1 can be restricted. In addition, as shown in FIG.
8 has a length and width set so that the first locking piece 8 does not protrude to the outside.

The second rotation restricting portion 19 is configured such that the first locking piece 8 is
When it engages with the rotation restricting portion 18, it has a locking concave portion 21 that engages with the bent portion 10 of the second locking piece 9, whereby the holding plate 2 rotates in the direction of the arrow shown in FIG. 1. Can be regulated. The second rotation restricting portion 19 is also configured so that the second locking piece 9 does not protrude to the outside.

Next, the operation and effect of the first embodiment constructed as described above will be described. First, in order to integrate the holding plate 2 and the clamp body 1, the shaft 5 of the support projection 4 is formed.
Through the guide groove 6 into the mounting hole 3. At this time, as shown in FIG. 1, it is necessary to set the holding plate 2 in a direction orthogonal to the clamp body 1 so that the holding grooves 111 to 114 are not closed.

Next, the integrated clamp body 1 and holding plate 2 are fixed to the bottom surface of the vehicle by fixing means (not shown). Thereafter, the tubular body P is held in the holding grooves 111 to 114 by fitting the tubular body P into the insertion ports 131 to 134 and pushing it in firmly. After this operation is repeated for each of the holding grooves 111 to 114, the holding plate 2 is rotated in the arrow direction shown in FIG. 1 to close each of the holding grooves 111 to 114. In accordance with this rotation operation, the first locking piece 8 bends and deforms so as to be lifted along the inclined surface 20 of the locking projection 17, and when it gets over this, it returns and engages with the first rotation restricting portion 18. I do. At the same time, the bent portion 10 of the second locking piece 9 engages with the locking recess 21 of the second rotation restricting portion 19, so that the holding plate 2
Are locked in both the rotation in the arrow direction and the rotation in the opposite direction, and the fixing operation of the tubular body P is completed.

If it is necessary to remove the tubular body P for repair work or the like, the first locking piece 8 is lifted up to bend and deform to a height exceeding the locking projection 17, and in this state, When the holding plate 2 is rotated in the opposite direction, the holding grooves 111 to 114 are opened, so that the tubular body P can be removed.

As described above, according to the first embodiment, after holding the tubular body P on the clamp body 1, it is only necessary to rotate the holding plate 2, and the operation during this time can be easily performed with one hand. . Further, since no screw tightening work is required, the number of parts is reduced and the number of work steps is reduced. Further, even when the replacement of the tubular body P is necessary, the tubular body holding function of the holding plate 2 does not deteriorate at all, unlike the conventional case of screwing. Therefore, the reliability for holding the tubular body can be maintained as it is even when it is used again.

FIG. 4 shows a second embodiment of the present invention. In this embodiment, the rotation operation direction at the time of the release / lock operation on the holding plate 2 in the first embodiment is limited to one direction. This can be operated in any direction. For this reason, in the holding plate 2, the locking portion K is formed to protrude symmetrically at the center of the side edge of the plate 2, and the rotation restricting portions S of the clamp body 1 are also arranged symmetrically. That is, the left and right side walls 141, 141 of the clamp body 1
At the upper edge of 142, a symmetrical slope 20 is formed so as to have an upward slope from both sides to the center, and a recess 22 with which the locking portion K is engaged is formed at the top. With such a configuration, the locking portion K and the rotation restricting portion S can be engaged or disengaged regardless of the direction in which the holding plate 2 is rotated, so that the degree of freedom of work can be increased. Enhanced benefits are obtained.

Various modifications can be considered for the form of retaining the holding plate 2 with respect to the clamp body 1. For example, contrary to the first and second embodiments, a supporting projection is formed on the holding plate side and the clamp body side is formed. It is conceivable that a guide groove is cut out from the side and led to the central projection storage space. Further, the center of rotation of the holding plate 2 does not necessarily need to be set at the center thereof, but may be set at the end.

[0021]

[Effects of the Invention] The effects of the present invention are as follows. After the tubular body has been fitted into the holding groove, it is only necessary to rotate the holding plate, so that one-handed operation is possible, and there is no troublesome screw tightening operation, so that the operation can be performed efficiently.
