Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a clamp structure for attaching members used in, for example, an automobile.

[Conventional technology]

BACKGROUND ART Conventionally, member mounting clamps used in automobiles and the like have been molded from a resin material or the like, and as this clamp structure, for example, they are attached to a door inner panel of a vehicle door, and have a long shape for remote operation of a door lock mechanism. The clamp for supporting the link will be described as an example. As shown in FIGS. 4 and 5, the clamp 50 is a sliding portion that supports the elongated link 1 slidably in its axial direction. 20 and a holding portion 40 for attaching and holding the sliding portion 20 to the door inner panel 30 which is a base body. The holding portion 40 is locked in a hole 310 formed in the door inner panel 30. The clamp 50 for supporting the link 1.
Is attached to the door inner panel 30.

Specifically, by vertically pushing the holding portion 40 of the clamp 50 into the hole 310 of the door inner panel 30, the engagement of the holding portion 40 with the hole 310 of the door inner panel 30 due to the bending of the claw portion 60 formed in the holding portion 40. The clamp 50 is attached to the door inner panel 30 in order to prevent the link 1 supported by the clamp 50 from protruding as much as possible from the door inner panel 30. At the sliding part 20 and the holding part 40, the door inner panel 30
Is formed so as to have a substantially constant distance, and the sliding portion 20 and the holding portion 40 are formed so as to be separated from each other with a predetermined distance.

As a conventional technique showing such a clamp structure, for example, Japanese Utility Model Laid-Open No. Sho 62-69563 (Shokai Sho 60-
160942).

[Problems to be solved by the invention]

However, in the case of the clamp structure disclosed in FIGS. 4 and 5 and Japanese Utility Model Laid-Open No. 62-69563, the clamp 50 is used.
In the case where the holding portion 40 and the sliding portion 20 are formed apart from each other by a predetermined distance, that is, the sliding portion 20 is formed immediately above the holding portion 40 that is locked in the hole 310 of the door inner panel 30. Therefore, when the link 1 supported by the sliding portion 20 slides in the axial direction, a sliding force also acts on the sliding portion 20 and is locked in the hole 310 of the door inner panel 30. A force in the rotational direction indicated by the arrow C acts on the sliding portion 20 with the holding portion 40 that is a fulcrum as a fulcrum, and the sliding resistance when the link 1 slides increases.
Therefore, the proper operation of the link 1 may be affected, and abnormal noise may occur.

Further, since the clamp 50 has directionality, that is, the clamp 50 can be mounted only in the directions shown in FIGS. 4 and 5, this mounting direction is indicated in order to mount it without error. However, the mounting structure is complicated and the mounting method is complicated.

Further, the holding force with respect to the door inner panel 30 (hole 310) for attaching the clamp 50 to the door inner panel 30 is sufficient because the bending of the claw portion 60 formed in the holding portion 40 of the clamp 50 is utilized. The claw portion 60 is required to have a predetermined length in order to achieve sufficient bending and holding force, and the claw portion 60 becomes large in size, so that the holding portion locked in the hole 310 of the door inner panel 30. The claw portion 60 of 40 largely protrudes from the door inner panel 30. Therefore, the claw portion 60 of the holding portion 40 that greatly protrudes may interfere with other components inside the door.

Furthermore, in the method of attaching the clamp 50 by the claw portion 60 of the holding portion 40 as described above, it is extremely difficult to correct the above-mentioned mistaken attachment, that is, to remove the clamp 50, and a dedicated tool or the like is required for removal. Therefore, the work etc. becomes complicated.

Therefore, the object of the present invention is to improve the operation of the link supported by the clamp by sliding properly, prevent abnormal noise, etc., and to improve the attachment / detachment of the clamp without causing an error in the mounting direction. And to prevent interference with other parts.

[Means for solving problems]

Therefore, the present invention has the above-mentioned problems in that the holding portion and the sliding portion of the clamp are formed on the same line, the clamp is rotated with respect to the base body so as to sandwich the base body, and the clamp is attached and slid. The present invention is intended to solve the problem by making the inner surface of the moving portion a tapered surface and providing a protrusion serving as a guide in the center thereof.

More specifically, it will be described with reference to the reference numerals in FIG. 1. A sliding portion 2 that slidably supports the long link 1 in its axial direction.
And a holding part 4 for mounting and holding the sliding part 2 on the base body 3, the clamp 5 being adapted to be mounted by locking the holding part 4 of the clamp 5 in the hole 31 of the base body 3. In the structure, the holding portion 4 and the sliding portion 2 are formed on the same line, the holding portion 4 and the hole 31 of the base body 3 are formed in a rectangular shape, and the holding portion 4 and the sliding portion 2 are formed.
A flange portion 6 that elastically contacts with the base body 3 is formed between and, and the inner surface of the sliding portion 2 is formed into a tapered surface that gradually expands from the central portion in the longitudinal direction toward both ends. Protrusions 12 that come into contact with the outer peripheral surface of the elongated link 1 at a plurality of positions are formed at the center of the inner surface in the longitudinal direction, and the holding portion 4 is inserted into the hole 31 of the base body 3 and rotated, whereby the collar is formed. The clamp 5 is attached so that the base body 3 is sandwiched between the collar portion 6 and the holding portion 5 by the elastic contact force of the portion 6.

[Action]

According to the above-mentioned means, the clamp 5 can be easily attached / detached only by rotating with respect to the base body 3 (hole 31), and the elastic contact force of the flange portion 6 allows the base body 3 to be interposed between the flange portion 6 and the holding portion 4 of the clamp 5.
Since the clamp 5 can be securely attached by sandwiching the clamp 5, the workability of attaching and detaching the clamp 5 can be improved, and there is no mounting directionality of the clamp 5, so that erroneous attachment can be prevented and the claw portion and the like can be prevented. Since the mounting can be performed securely and not by locking, the holding portion 4 of the clamp 5 does not significantly project, and interference with other parts can be prevented.

Further, since the sliding portion 2 of the link 1 is formed immediately above the holding portion 4 on the same line, a force that causes the sliding portion 2 to rotate with respect to the holding portion 4 does not act at all. Since it is possible to prevent an increase in sliding resistance when the link 1 slides, it is possible to properly operate the link 1 and prevent abnormal noise. Further, the inner surface of the sliding portion 2 is a tapered surface that spreads to both end sides in the longitudinal direction, and the protrusion 12 at the central portion thereof supports the link 1 at a plurality of points on the outer peripheral surface thereof. Link 1
It is possible to secure a smooth operation and to keep the sliding resistance of the link 1 constant.

〔Example〕

An embodiment of the present invention will be described below with reference to the accompanying drawings.

1 to 3 show an embodiment of the present invention, and FIG. 1 is a sectional view taken along the line I--I of FIG. 2 showing a link supporting state to a clamp attached to a base body, and FIG. Is II in Fig. 1
FIG. 3 is a sectional view taken along the line III-III in FIG.

As a clamp structure, for example, a clamp that is attached to a door inner panel of an automobile door and supports a long link for remote operation of a door lock mechanism will be described. As shown in FIG. The clamp 5 is a sliding portion 2 that slidably supports the elongated link 1 in its axial direction.
And a holding portion 4 for attaching and holding the sliding portion 2 to the door inner panel 3 which is a base body. By locking the holding portion 4 in the hole 31 of the door inner panel 3, the link is formed. A clamp 5 for supporting 1 is configured to be attached to the door inner panel 3.

In the clamp structure configured as described above, the sliding portion 2 is formed immediately above the holding portion 4 so that the holding portion 4 and the sliding portion 2 of the clamp 1 are on the same line as shown in FIG. At the same time, as shown in FIG. 2, the holding portion 4 and the hole 31 of the door inner panel 3 are both formed in a rectangular shape,
Moreover, as shown in FIG. 1, in order to mount the clamp 5 on the lower surface of the sliding portion 2 between the holding portion 4 and the sliding portion 2, when the holding portion 4 and the hole 31 are locked, the door inner panel 3 is attached. The flange portion 6 is elastically contacted with the upper surface of the.

Then, after inserting the rectangular holding portion 4 of the clamp 5 into the rectangular hole 31 of the door inner panel 3, the clamp 5 is rotated as shown by an arrow A in FIG. The door inner panel 3 is sandwiched between the collar portion 6 and the holding portion 4 by the elastic contact force of the collar portion 6 with the upper surface of the door inner panel 3, so that the clamp 5 is securely and firmly attached. It is designed to be attached to 3.

Specifically, first, as shown in FIG. 1, a slide for slidably supporting a long link 1 for remote operation of a door lock mechanism in a direction of an arrow B (see FIG. 3) which is an axial direction thereof. Moving part 2
However, so that the sliding portion 2 is on the same line as the holding portion 4 for mounting and holding the sliding portion 2 in the hole 31 of the door inner panel 3.
The holding portion of the clamp 5 which is formed immediately above the hole and is formed in the door inner panel 3 in a rectangular shape as shown in FIG. 2 and which is locked in the rectangular hole 31. 4 is also formed in a rectangular shape.

Further, as shown in FIG. 1, between the holding part 4 and the sliding part 2, a lower surface of the sliding part 2 is provided with a flange part 6 having an elastic contact force for elastically contacting the upper surface of the door inner panel 3. In addition, the distance between the collar portion 6 and the holding portion 4 in the free state shape of the collar portion 6 is determined by the door inner panel 3
It is set to be smaller than the plate thickness of the clamp 5
When the holding portion 4 and the hole 31 are locked for mounting, the flange portion 6 is bent by the elastic contact force and thus the door inner panel 3 is attached.
The clamp 5 is securely and firmly attached to the door inner panel 3 by sandwiching the door inner panel 3 between the flange portion 6 and the holding portion 4 by elastically contacting the upper surface of the door inner panel 3.

On the other hand, when inserting the rectangular holding portion 4 into the rectangular hole 31 in order to attach the clamp 5 to the door inner panel 3,
In order to prevent the holding portion 4 from interfering with the edge of the hole 31 or the like, the outer shape of the holding portion 4 is formed smaller than the hole 31 as shown by the chain double-dashed line in FIG. After inserting the holding portion 4 into the hole 31, by rotating in the direction of arrow A, the contact surface 7 (the portion shown by hatching in FIG. 2) on the long side of the rectangular holding portion 4 becomes
The holding portion 4 comes out of the hole 31 because it comes into contact with the hole edge on the short side of the rectangular shape 31 of the door inner panel 3, and together with the elastic contact of the flange 6 with the surface of the door inner panel 3 described above. The clamp 5 can be securely and firmly attached without the need.

Then, the sliding portion 2 of the clamp 5 attached in this way
The long link 1 is supported by the link 1.
3 only slides in the direction of arrow B, which is the axial direction thereof, as shown in FIG. 3, and has a long shape, so that the link 1 is supported on the sliding portion 2 of the clamp 5. When the clamp 5 is attached in this state, the rotation of the clamp 5 can be restricted by the link 1, and the clamp 5 in the attached state can be prevented from coming off due to rotation.

Here, in order to mount the clamp 5 as described above, the workability in the case of inserting the holding portion 4 into the hole 31 and rotating in the direction of arrow A in FIG. 2 is improved, that is, to the door inner panel 3 of the clamp 5. In order to improve the mountability of the above, the contact surface 7 of the holding portion 4 with the door inner panel 3 is provided with a slanted guide portion 8 as shown in FIG. 1 and FIG. At the time of rotation in the A direction, the guide portion 8 reduces the resistance at the time of rotational mounting and enables smooth rotation, and the mounting state as shown in FIG. 1 can be obtained.

Further, the mounting work of the clamp 5 by such rotation is
The operator grips the clamp 5 with his / her finger, and in order to make it easier to grip the clamp 5 with his / her finger during this work, as shown in FIG. 1 and FIG. A large parallel flat surface portion 9 is formed on the side surface as a finger grip allowance, so that it is easy to grip with a finger and work by rotation is easy.

Further, in order to mount the clamp 5, when the holding portion 4 is inserted into the hole 31 of the door inner panel 3 and is attached by rotation in the direction of arrow A, it contacts with both long sides of the hole 31 as shown in FIG. Therefore, a cylindrical portion 10 is formed between the holding portion 4 and the flange portion 6 so as to have a diameter substantially the same as the short side of the hole 31. It is configured to prevent backlash due to movement or the like.

Next, as shown in FIG. 3, a protrusion 12 is formed at a substantially central portion in the longitudinal direction of the sliding surface 11, which is an inner side surface of the sliding portion 2 of the clamp 5, and by the protrusion 12, By securely supporting the link 1 in the sliding portion 2 and forming the sliding surface 11 so as to expand in a taper shape from the protruding portion 12 toward the outer side in the longitudinal direction, the clamp 5 is slightly slanted. Link 1 even when attached to
When the support is assembled, the link 1 does not come into contact with the tapered sliding surface 11 of the sliding portion 2 of the clamp 5, and the link 1 can be easily attached to obtain the supporting state as shown in FIG. Is configured.

It should be noted that, as shown in FIG. 1, the holding portion 4 has a small protrusion amount from the door inner panel 3 into the door in order to avoid interference with other components in the door when the clamp 5 is attached. It is formed in.

Therefore, the sliding portion 2 for supporting the link 1 in the clamp 5 is formed on the same line as the holding portion 4 which is locked in the hole 31 of the door inner panel 3 and is directly above.
Even when the link 1 slides in the direction of arrow B, a force for rotating the sliding portion 2 with respect to the holding portion 4 does not act. Moving part 2
It is possible to prevent an increase in the sliding resistance with respect to each other, to always make the operation of the link 1 proper, and to prevent the generation of abnormal noise during sliding.

Further, since the clamp 5 can be mounted only by rotating, the mounting directionality of the clamp 5 is not limited, that is, there is no mounting directionality, and as described above, the flat surface portion of the outer surface of the sliding portion 2 of the clamp 5 is used. Since the mounting work by pinching 9 with a finger is sufficient and there is no error in the mounting direction of the clamp 5, the clamp 5 can always be mounted properly without instructing the mounting direction.

Further, the clamp 5 is firmly and firmly attached by only rotating the hole 31 of the door inner panel 3 so that the elastic force of the flange 6 sandwiches the door inner panel 3 between the flange 6 and the holding portion 4. Therefore, the work for mounting the clamp 5 can be performed very easily and smoothly, and the mounting structure of the clamp 5 is complicated in combination with the proper mounting due to the lack of mounting directionality as described above. It never happens, and the mounting method does not become complicated at all.

Moreover, the removal of the clamp 5 can be performed very easily and smoothly by the method reverse to the above-mentioned attachment without using a dedicated tool for attachment, etc. It can be greatly improved.

Furthermore, the holding force with respect to the door inner panel 3 (hole 31) for attaching the clamp 5 to the door inner panel 3 is determined by the elastic contact force of the flange portion 6 and the holding portion 4.
It is formed by sandwiching the door inner panel 3 between and, and further, rotation, vertical movement, rattling, etc. of the clamp 5 which is firmly and firmly attached by this is not caused. 4 and FIG. 5, the holding portion 4 can be formed in an extremely small size instead of being attached by the locking of the claw portion 60 and the like as in the configuration shown in the prior art, and therefore the holding portion 4 can be formed inside the door. It is possible to prevent interference with other parts without significantly protruding.

In the above embodiments, the structure of the clamp 5 attached to the door inner panel 3 for supporting the remote control link 1 of the door lock mechanism inside the door has been described as an example, but the present invention is not limited to this. The present invention can be applied to any clamp structure for supporting and attaching a member without any need.

[Effect of device]

As described above, the present invention forms the holding portion for attaching to the base body in the clamp and the sliding portion for slidably supporting the elongated link on the same line, and the collar between these portions. The clamp is attached to the base body by forming a portion, rotating the clamp with respect to the base body, and sandwiching the base body between the flange portion and the holding portion by the elastic contact force of the flange portion. Reliable and strong only by rotating with respect to the base,
Moreover, because it can be easily and smoothly removed,
The workability of attaching and detaching the clamp can be greatly improved, and since the clamp has no mounting directionality, it is possible to prevent erroneous mounting of the clamp, and to always mount it properly and securely.

Further, since the clamp can be securely mounted without being locked by the claws and the like, and the holding portion of the clamp can be downsized, the holding portion is largely projected in the door. There is no problem, and it is possible to prevent interference with other parts.

Further, since the sliding portion is formed on the same line of the holding portion, when the link slides, there is no force to rotate the sliding portion with respect to the holding portion, and the sliding of the link does not occur. Since it is possible to prevent an increase in dynamic resistance, it is possible to properly operate the link, and it is possible to prevent abnormal noise and the like from occurring. The inner surface of the sliding portion is a taper surface that expands on both end surfaces in the longitudinal direction, and a protrusion for supporting the link at a plurality of points on its outer peripheral surface is provided at the center of the inner surface of the sliding portion. Even if the relative orientation is deviated, the smooth operation of the link can be ensured and the sliding resistance of the link can be made constant.
