Description

The present invention relates to a support device that defines a positional relationship between two members.

Two members, for example, a fixed member (for example, a fender) in a vehicle and a movable member (for example, a hood, a trunk lid, an openable roof for an open car, etc.) are aligned in a predetermined positional relationship even when subjected to vibration or the like. Is desired. For this reason, support devices such as those disclosed in Patent Documents 1 and 2 have been proposed.

In the supporting devices described in Patent Document 1 and Patent Document 2, basically, the stopper member inserted into the supporting member is positionally adjustable in the axial direction by a load equal to or more than a predetermined value in the axial direction. In the temporarily fixed state where the adjustment is completed, the stopper member is permanently fixed by the lock member. According to the one described in Patent Document 1, the main fixing by the lock member is performed by inserting the lock member into the hollow portion formed in the shaft portion of the stopper member. Moreover, the thing of patent document 2 is performed by tightening the lock nut screwed to the stopper member.

DE10200990444166A1 (German patent publication) Japanese Patent No. 4329888

In the above-mentioned Patent Document 1, since a hollow portion is formed in the shaft portion of the stopper member for the purpose of permanent fixing, there remains a problem in robustness. Further, in the one described in Patent Document 2, the lock nut needs to be rotationally operated for the purpose of permanent fixing, so that there remains a problem in operability.

The present invention has been made in view of the above circumstances, and an object thereof is to provide a supporting device that can satisfy both robustness and operability.

In order to achieve the above object, the following solution is adopted in the present invention. That is, as described in claim 1,
A stopper member having a stopper portion and a shaft extending from the stopper portion;
A support member having a hole through which the shaft is inserted;
A slide member slidably held by the support member,
Have
On the shaft body, a plurality of locking grooves are formed at intervals in the axial direction,
The shaft member is temporarily fixed to the inner surface side of the hole of the support member by the load of a predetermined amount or more in the axial direction of the shaft member when engaged with the locking groove so that the shaft member can be positionally adjusted in the axial direction. A shaft holder is formed,
The slide member is slidable in a direction orthogonal to the axial direction of the shaft body, and an engaging position for permanently fixing the shaft body when engaged with the locking groove and a retracting position from the engaging position. And a retracted position where the temporary fixing is performed,
An engaging position of the slide member with respect to the engaging groove and an engaging position of the engaging groove of the shaft holding portion are different from each other in the axial direction of the shaft.
Is done.

According to the above-mentioned solution method, it is not necessary to form the hollow portion into which the locking member is inserted in the shaft body for the final fixing, and the robustness can be ensured. Further, since the main fixing is only required to slide the slide member toward the engaging position, operability is also satisfied. Further, since the position of the loose engagement for temporary fixing and the position of the rigid engagement for permanent fixing are made different in the axial direction of the shaft body, the roles are divided, and therefore the loose engagement by temporary fixing is not possible. It is also preferable in terms of preventing the fixation from being adversely affected.

A preferred mode based on the above solution method is as set forth in claim 2 and the subsequent claims. That is,
The slide member is formed of a plate-shaped member having a thickness capable of engaging with one of the plurality of locking grooves,
An operation portion for sliding the slide member by a manual operation is formed at an end portion of the slide member,
This is done (corresponding to claim 2). In this case, the slide member can be easily slid using the operation portion. Further, since the slide member can be engaged with the locking groove by utilizing its thickness, the slide member can have a simplified structure, which is extremely preferable in terms of downsizing.

At least one of the shaft body and the slide member is made of metal (corresponding to claim 3). In this case, it is preferable in order to sufficiently secure the strong fixation in the main fixation.

The engagement allowance of the slide member with respect to the engagement groove is larger than the engagement allowance of the shaft body holding portion with respect to the engagement groove (corresponding to claim 4). In this case, it is preferable in order to sufficiently secure the strong fixation in the main fixation.

The locking groove is composed of a plurality of parallel grooves parallel to each other and a thread groove formed on the tip end side of the shaft body with respect to the parallel grooves,
While the slide member is engaged with the parallel groove, the shaft body holding portion is engaged with the screw groove.
This is done (corresponding to claim 5). In this case, the position of the stopper portion in the temporary fixing can be finely adjusted by using the screw groove at the time of temporary fixing while allowing the main fixing to be easily performed only by engaging the slide member with the parallel groove. ..

The slide member is formed with an insertion hole through which the shaft is inserted and which is slidable between the retracted position and the engagement position in the inserted state.
When the slide member is slid forward from the retracted position to the engagement position, the inner edge portion on the rear side of the insertion hole is engaged with the locking groove to perform main fixing.
This is done (corresponding to claim 6). In this case, it is preferable in that the sliding member is prevented from coming off from the radial direction of the stopper member while simplifying the structure for the main fixing.

The slide member is configured to slide on the surface of the support member on the stopper portion side,
A first member that abuts a front end of the slide member at the retracted position on a surface of the support member on the stopper portion side and temporarily restricts the slide member from sliding toward the engagement position. A nail part is formed,
The slide member is formed with an insertion hole into which the first locking claw portion is fitted at the engagement position,
When the slide member is slid forward from the retracted position to ride over the first locking claw portion to reach the engagement position, the first locking claw portion has an inner peripheral edge on the front side of the insertion hole. The sliding member is restricted from sliding from the engaging position to the retracted position by being engaged with the portion,
This is done (corresponding to claim 7). In this case, the slide member can be firmly held by the support member, and in particular, when the slide member is fully fixed, the load input to the slide member via the stopper portion can be firmly received by the support member. Further, the first locking claw portion prevents the slide member from inadvertently moving to the engagement position at the temporary fixing position, and firmly maintains the main fixing position when the main fixing is performed. be able to.

A second locking claw portion is formed on the support member, the second locking claw portion being in contact with the slide member when in the retracted position to restrict the slide member from sliding further rearward from the retracted position, This is done (corresponding to claim 8). In this case, it is possible to prevent the slide member from being retracted from the retracted position at the time of temporary fixing, that is, to ensure that the slide member is maintained at the retracted position and the position of the stopper member can be easily adjusted. Is preferable.

The supporting member is formed of a synthetic resin, and has a flange portion that slidably supports the slide member, and a tubular portion that extends from the flange portion and has the hole portion,
The shaft body holding portion is formed as a plurality of locking claw portions that are projected from the inner surface side of the hole portion at intervals in the circumferential direction and that are engaged with the locking groove.
This is done (corresponding to claim 9). In this case, a specific structure of the position adjusting portion for temporary fixing can be provided. In particular, it is preferable in securing the loose engagement between the shaft body and the support member at the temporary fixing position.

According to the present invention, both robustness and operability can be satisfied.

1 to 6 showing the supporting device S according to the present invention, 1 is a supporting member, 20 is a stopper member, and 30 is a sliding member. In the following description, with respect to the sliding direction of the slide member 30, the direction toward the engaging position is referred to as the front and the direction toward the retracted position is referred to as the rear.

As shown in FIGS. 5 to 10, the support member 1 has a flange portion 2 and a tubular portion 3 extending downward from the flange portion 2. The inside of the cylindrical portion 2 is a hole portion 4 into which the stopper member 20 is inserted. A plurality of (two in the embodiment) locking claws 5 for temporary fixing are formed at the bottom (lower part) of the hole 4 so as to project to the inner surface side of the hole 4 at intervals in the circumferential direction. ..

On the outer surface side of the tubular portion 2 of the support member 1, a locking claw portion 6 for mounting is formed so as to face the flange portion 2. The support member 1 is attached to the fixing member 50 such as a fender in an automobile by using the flange portion 2 and the locking claw portion 6 (see FIG. 9 ). That is, the insertion of the cylindrical portion 3 into the mounting hole 50a of the fixing member 50 is performed while the locking claw portion 6 is elastically deformed toward the radially inner side of the cylindrical portion 3, and the flange portion 2 is fixed to the fixing member 50. In the state of being seated at, the locking claw portion 6 is elastically returned toward the radially outer side of the tubular portion 3, so that the fixing member 50 is sandwiched between the locking claw portion 6 and the flange 2. (Attachment state of the support member 1 to the fixing member 50).

A plurality of guide protrusions 7, a first locking claw 8 and a second locking claw 9 are formed on the upper surface of the flange 2 of the support member 1. Such a supporting device 1 is generally formed as an integrally molded product made of synthetic resin.

As shown in FIGS. 11 and 12, the stopper member 20 includes a shaft body 21 having a large diameter at the base end portion and a stopper portion 22 made of an elastic member fixed to the base end portion of the shaft body 21. Have. The shaft body 21 is made of, for example, an iron-based metal in the embodiment, but may be made of a synthetic resin.

Two types of locking grooves are formed on the outer periphery of the shaft body 21. That is, a thread groove (male thread portion) 23 serving as a locking groove for temporary fixing is formed on the outer periphery of the shaft body 11 on the tip end side (the side far from the stopper portion 12). Further, a parallel groove 24 serving as a locking groove for main fixing is formed on the outer periphery of the shaft body 21 on the base end side.

The parallel groove 24 is formed as a gap between the projecting portions 25 by projecting a plurality of annular projecting portions 25 surrounding the shaft body 21 in the axial direction of the shaft body 21 with a small pitch at equal intervals. ing. The depth of the parallel groove 24 (corresponding to the protruding length of the protruding portion 25) is made deeper than the depth of the screw groove 23.

Details of the slide member 30 are shown in FIGS. The slide member 30 is formed of, for example, an iron-based metal plate in the embodiment, but may be formed of synthetic resin. The thickness of the slide member 30 is slightly smaller than the gap between the parallel grooves 24 (the gap between the protrusions 25). The slide member 30 includes a flat plate-shaped main body portion 31 placed on the upper surface of the flange portion 2 of the support member 1, and an operation portion that is bent upward by approximately 90 degrees from one end portion (rear end portion) of the main body portion 31. 32, and. Further, the other end portion (front end portion) of the main body portion 31 is a temporary stopper portion 33 bent upward by approximately 30 to 45 degrees.

A dowel hole-shaped insertion hole 34 is formed in the body portion 31 of the slide member 30. That is, the insertion hole 34 has a shape in which the large diameter hole 34a and the small diameter hole 34b communicate with each other. The large-diameter hole 34a is located on the temporary stopper portion 33 side, and is slightly larger than the outer diameter of the parallel groove 24 portion (projection portion 25) of the stopper member 20. The small-diameter hole 34b is located on the side of the operating portion 32, and is smaller than the outer diameter of the parallel groove 24 portion (projection portion 25) and larger than the outer diameter of the parallel groove 24 at the bottom.

A locking hole 35 extending in the front-rear direction is formed in the slide member 30 behind the insertion hole 34 (that is, on the operation portion 32 side). Then, the slide member 30 is held by the support member 1 so as to be slidable in the front-rear direction while the main body portion 31 is placed on the upper surface of the flange portion 2 of the support member 1 using the guide protrusion portion 7 as a guide. .. The guide protrusion 7 has a cross-sectional shape that covers the side edge of the main body 31 from above, and restricts the slide member 30 from separating upward from the upper surface of the flange 2.

Here, the shaft body 21 of the stopper member 20 is inserted into the hole portion 4 of the support member 1 through the insertion hole 34 of the slide member 30 held by the support member 1. Initially, as shown in FIGS. 1, 2, 5, and 6, the slide member 30 is set to the retracted position (retracted position) located rearward.

Even when the slide member 30 is in the retracted position, the locking claw portion 5 of the support member 1 is engaged with the thread groove 23 formed in the shaft body 21 to be in the temporary fixed position. At this temporary fixing position, by applying a load more than a predetermined amount to the stopper member 20 in the axial direction, the locking position of the locking claw portion 5 with respect to the thread groove 23 is changed, and the position adjustment of the stopper member 20 ( The protruding length of the stopper member 20 from the support member 1) can be adjusted. In other words, the movable member (not shown) presses the stopper portion 22 of the stopper member 20 to bring the stopper portion 22 into contact with the movable member in a predetermined alignment position with the fixed member 50. (Vibration or the like prevents the movable member from being displaced with respect to the fixed member 50). The position can be finely adjusted by rotating the stopper member 20.

When the slide member 30 is in the retracted position, the shaft body 21 is inserted through the large diameter hole 34a of the insertion holes 34 (see, for example, FIGS. 1 and 2). Further, in this retracted position, the second locking claw portion 9 formed in the support member 1 is located in the locking hole 35 formed in the slide member 30, and the inner peripheral edge portion on the front side of the locking hole 35 is located. The slide member 30 is prevented from moving further rearward from the retracted position by contacting with (see FIG. 1, FIG. 2, FIG. 5, and FIG. 6). Further, the temporary stopper portion 33 formed on the front end of the slide member 30 is brought into contact with the first locking claw portion 8 formed on the support member 1 to slide the slide member 30 forward (to the engagement position). Slide toward) is temporarily regulated (see FIGS. 1, 5, and 6).

FIG. 5 shows a state in which the stopper portion 20 is shallowly inserted into the support member 1. FIG. 6 shows a state in which the stopper member 6 is inserted deeper into the support member 1 from the state of FIG. For example, the state of FIG. 6 is a state in which a movable member (not shown) is in a predetermined alignment position with respect to the fixed member 50.

From the state of the retracted position shown in FIG. 6, the slide member 30 passes over the first locking claw portion 8 by applying a pressing force forward with the fingers to the operation portion 32 of the slide member 30 by a predetermined amount or more. It is slid toward the front, and finally brought to the engagement position. At this engagement position, the first locking claw portion 8 is located in the insertion hole 34. Then, the inner peripheral edge portion on the front side of the insertion hole 34 abuts on the first locking claw portion 8, whereby the slide member 30 can slide rearward (toward the retracted position) from the engagement position. It is strongly regulated (see FIGS. 3 and 4). That is, in the embodiment, the insertion hole 34 also serves as a locking hole that restricts the slide member 30 from sliding toward the retracted position.

At the engagement position, the slide member 30 is engaged with the parallel groove 24 of the shaft body 21 of the stopper member 20. More specifically, the shaft body 21 is in a state of being inserted into the small diameter hole 34b of the insertion holes 34 of the slide member 30, and the rear inner peripheral edge portion of the small diameter hole 34b is deeply inserted into the parallel groove 24. The engaged state is set. As a result, the stopper member 20 is brought into the main fixed state in which the axial movement of the stopper member 20 is firmly restricted.

In the state of the engagement position, the engaging action of the slide member 30 with respect to the parallel groove 24 becomes stronger than the engaging action of the locking claw portion 5 with respect to the screw groove 23 for temporary fixing. .. That is, the locking claw portion 5 is only partially present in the circumferential direction of the shaft body 21, and the insertion depth into the thread groove 23 is also relatively small, so that the engagement allowance is small. On the other hand, the engagement of the slide member 30 with respect to the parallel groove 24 is deep and long in the circumferential direction of the shaft body 21 (a length of about 180 degrees in the circumferential direction), and the engagement margin is extremely large. To be taken. Further, since the locking claw portion 5 for temporary fixing can also be elastically deformed, the engaging action at the time of main fixing is sufficiently larger than the engaging action at the time of temporary fixing.

With respect to the shaft body 21, the engagement position when the main body is fixed (the position of the slide member 30) and the engagement position when the body is temporarily fixed (the position of the locking claw 5) are the axial direction of the shaft body 21. Since the positions are spaced apart from each other, the stopper member 20 can be firmly fixed to the support member 1 without being affected by the temporary fixing.

Although the embodiments have been described above, the present invention is not limited to the embodiments, and appropriate modifications can be made within the scope of the claims. The support device S according to the present invention is not limited to an automobile, but can be applied to any appropriate device that is interposed between two members and is required to maintain the positional relationship between the two members in a predetermined relationship. The locking groove formed in the shaft body 21 may be configured by only one of the parallel grooves 24 and the thread groove 23 without dividing the locking groove. Of course, the object of the present invention is not limited to what is specified, and also implicitly includes providing what is expressed as substantially preferable or advantageous.
