Description

DETAILED DESCRIPTION OF THE INVENTION "Industrial application" The present invention relates to an improvement of a fixing clip used for fixing a mounting part such as an automobile garnish to a predetermined panel.

"Prior Art" As a conventional fixing clip of this type, Japanese Patent Laid-Open No. 52-13
There are those disclosed in Japanese Patent No. 3464 or Japanese Utility Model Laid-Open No. 62-3511.

Although not specifically shown in the drawings, the conventional fixing clip is composed of a first member that holds a mounting component and a second member that is engaged with a mounting hole of a panel in any one of them.
The former first member has a base body connected to the attachment member and a pair of support pieces projecting from the front end surface of the base body at a predetermined interval, and a wide hole portion is formed in the base body. T consisting of a narrow hole
It is configured to form a V-shaped locking hole.

The latter second member has a structure in which a closed annular leg body that can be elastically engaged with the mounting hole of the panel and a neck piece that engages with the T-shaped engagement hole are integrally formed. There is.

When fixing the mounting component to the panel using the first and second members, first, the T-shaped locking of the first member is performed from the space defined between the pair of support pieces. The neck piece of the second member is inserted into the wide hole portion of the hole, and then the narrow width portion of the neck piece is locked to the narrow hole portion of the T-shaped locking hole so as to be connected to the attachment part. After the one member and the second member are integrated, the legs of the second member are elastically engaged with the mounting holes of the panel, whereby the mounting component is fixed to the panel.

[Problems to be solved by the invention] However, in such a conventional fixing clip, as a means for integrating the first member and the second member, a wide hole portion and a narrow hole are provided on the base side of the first member. A T-shaped locking hole is formed, and a neck piece that locks in the locking hole is formed on the second member side. The neck piece is a wide hole portion of the T-shaped locking hole. When moving from the to the narrow hole portion and locking, no sense of moderation can be obtained, so it is not possible to easily confirm that the neck piece has locked in the narrow hole portion of the locking hole, Due to this, not only can work efficiency not be expected sufficiently, but it is often found that the first member and the second member are integrated in a defective state.

In addition, in the conventional fixing clip, when it is necessary to remove the attachment part from the panel, the neck piece of the second member is changed from the narrow hole portion of the T-shaped locking hole of the first member to the wide hole portion. It is possible to release the integrated state of the first member and the second member for a while by moving the.
Since the work can be performed only from one direction, there was a fear that the work would be difficult due to the limitation of the directionality.

"Means for Solving the Problems" The present invention was developed in order to effectively solve such a conventional problem, and is provided in the first member for holding the mounting parts and the mounting hole of the panel. Assuming a fixing clip composed of a second member to be engaged, the first member forms a holding means for holding the attachment component on the upper side of the shaft body, and at the opposite side surface side of the lower shaft body. A pair of spring arm pieces are formed, and a lock shoulder is formed on each of the other side surfaces of the shaft lower portion which face each other, and the second member is a through hole for accommodating the shaft member of the first member inside the main body. And a pair of guide holes through which the lock shoulder portion is inserted, are formed continuously on both sides of the through hole, and a slope that regulates the insertion posture of the lock shoulder portion on the wall surface that defines the guide holes. The structure that forms the surface portion is adopted.

According to the “action”, according to the present invention, one of the guide holes continuously formed on both sides of the through hole of the second member is selected, and the lock on the first member side is locked in the one guide hole. When the shoulder portion is inserted, initially, the shaft body of the first member moves the guide member and the through hole while bending the spring arm piece existing on the guide hole side inward by the restricting action of the inclined surface portion with respect to the lock shoulder portion. Although it is inserted in a state of inclining inside, when the lock shoulder passes through the guide hole, the shaft body is stored vertically in the through hole due to the spring pressure of the spring arm piece that has been bent inward. At the same time, the lock shoulder at the lower part of the shaft is automatically locked to the lower end opening end of the through hole, and the first member and the second member are integrated.

Therefore, in such an integrated work, at the same time when the lock shoulder passes through the guide hole, the lock shoulder is moved to the through hole with a very clear detent feeling caused by the spring pressure of the spring arm piece. Since it will be locked to the opening edge of the lower end, it can be immediately confirmed that the first member and the second member are integrated, resulting in not only excellent workability but also the first and second members. There is no need to worry about being integrated in a defective state.

Therefore, if the attachment part is held on the upper part of the first member through the holding means and then the main body of the second member is inserted into the attachment hole of the panel, the second member is securely attached to the attachment hole. Therefore, this causes the mounting component to be fixed to the panel.

Also, when it becomes necessary to remove the mounting part from the panel, if the shaft side of the first member protruding downward from the main body of the second member is pressed toward one of the spring arm pieces,
Since the spring arm piece existing in the pressing direction bends inward and the locking of the lower end opening edge of the through hole of the lock shoulder portion can be easily released, in such a state, the lock shoulder portion of the first member is guided into the guide hole. When it is pulled out from the shaft, the shaft is also pulled out together from the through hole, so that the mounting component can be removed from the panel.

[Examples] Hereinafter, the present invention will be described in detail with reference to an illustrated example. A fixing clip according to the example also includes a first member 1 for holding attachment parts and a panel, as shown in FIG. The second member 11 is attached to the mounting hole of
The second members 1 and 11 are integrally molded of synthetic resin, but the feature is that the first member 1 and the second member 11 are configured as follows.

That is, the former first member 1 has a large-diameter flange 3 and a small-diameter flange 4 which are separated from each other via the neck portion 5 on the upper part of the prismatic shaft body 2 of the former, while the lower part of the prismatic shaft body 2 is formed. A pair of spring arm pieces 6, 6 that expand upward and outward are integrally formed on opposite side surfaces, and the shaft body 2 is provided at the center of the lower end surface of the shaft body 2.
The laterally long lock piece 7 having a width larger than the width is integrally formed.

Therefore, in the present embodiment, both ends of the lock piece 7 project from the other facing side surfaces of the prismatic shaft body 2 by a certain amount as shown in the figure, and engage with the lower end opening edge of the through hole described later. However, the present invention is not limited to this, and it is optional to directly form the lock shoulder portions directly on the other opposing side surfaces of the shaft body 2.

Also, as shown in FIG. 2, the latter second member 11 has a through hole 13 at a size capable of accommodating the prismatic shaft body 2 of the first member 1 in the center of the inside of the rectangular main body 12 of itself. Along with the formation of the through hole 13, a pair of guide holes 14, 14 through which the lock piece 7 of the first member 1 is inserted are continuously formed. Therefore, each of the guide holes 14
Is for inserting the lock piece 7 larger than the shaft body 2,
Since it is set to be larger than the through hole 13 through which the shaft body 2 is inserted, the relationship between the two holes 13 and 14 is such that the two holes 13 and 14 open like a plane H shape.

Furthermore, in the second member 11, the lock pieces 7 are provided in the vertical direction on both wall surfaces on the through hole side that defines the guide holes 14.
The inclined surface portions 15 for restricting the insertion posture of the main body 12 are formed, and the flange 16 is integrally formed on the upper end edge of the main body 12,
In addition, a pair of elastic locking legs 17, 17 that lock with the hole edges of the panel mounting holes are formed on the opposing outer wall surfaces of the main body 12, respectively.

Therefore, when one of the guide holes 14 formed on both sides of the through hole 13 of the second member 11 is selected and the lock piece 7 of the first member 1 is inserted into the one guide hole 14, first, As shown in FIGS. 3A and 3B, the guide hole 1 is restricted by the restricting action of the inclined surface portion 15 with respect to both ends of the lock piece 7.
While bending one spring arm piece 6 existing on the 4 side inward,
The shaft body 2 of the first member 1 is smoothly inserted in the guide hole 14 and the through hole 13 in an inclined state.
In addition, at the time of such insertion, the other spring arm piece 6 on which the shaft body 2 is formed moves without change in the through hole 13.

Then, when the lock piece 7 passes through the guide hole 14, this time, as shown in FIGS. 4A and 4B, the shaft body 2 is penetrated by the spring pressure of the one spring arm piece 6 that has been bent inward. Thirteen
At the same time as it is completely housed in a vertical state, the protruding end portions of the lock piece 7 formed on the lower end surface of the shaft body 2 are
The lower end opening edge of the through hole 13 is automatically locked with a feeling of moderation.

Therefore, when the mounting component 21 is fixed to the panel 23 by using the first member 1 and the second member 11 having such a configuration, first, as described above, both sides of the through hole 13 of the second member 11 are first fixed. The lock piece 7 of the first member 1 is inserted into the arbitrary guide hole 14 formed in the above so that the shaft body 2 is housed in the through hole 13 in a vertical state, and at the same time, the lock piece 7 is inserted into the through hole 13. The first member 1 and the second member 11 are integrated by elastically locking to the opening edge of the lower end.

In the integration work, at the same time when the lock piece 7 passes through the guide hole 14, the lock piece 7 has both ends of the lock piece 7 with a very clear detent feeling brought by the spring pressure of the spring arm piece 6. Since the part is locked to the opening edge of the lower end of the through hole 13, it can be immediately confirmed that the first member 1 and the second member 11 are integrated, and the workability is extremely good. In addition, there is no concern that the first and second members 1 and 11 will be integrated in a defective state.

Therefore, this time, after holding the hole edge of the polishing-like hole 22 formed on the back surface side of the attachment part 21 between the large diameter flange 3 and the small diameter flange 4 of the first member 1, the main body 12 of the second member 11 is held.
5 is engaged with the mounting hole 24 of the panel 23, the second member 11 is securely engaged with the mounting hole 24 by the action of the pair of locking legs 17 and the flange 16 as shown in FIG. Therefore, as a result, the attachment part 21 is fixed to the panel 23.

Further, in such a fixed state, the mounting part 21 is attached to the panel 23.
If it becomes necessary to remove it from the second member 1,
When the lock piece 7 of the first member 1 protruding downward from the main body 12 of No. 1 is pressed in the direction of one of the spring arm pieces 6 (in the direction of the arrow in the figure) using a tool such as a driver, the pressing Direction, the spring arm piece 6 is forced to bend inward,
Since the locking of the lock piece 7 with respect to the lower end opening edge of the through hole 13 can be easily released, after that, the lock piece of the first member 1 is kept in the state in which the second member 11 is attached to the mounting hole 24. 7 is pulled out from the guide hole 14, the prismatic shaft 2
Also, since the attachment part 21 can be removed from the panel 23, the first member 1 and the second member 11 can be reused sufficiently.

Moreover, in this embodiment, since the pair of guide holes 14 and 14 are formed on both sides of the through hole 13, it goes without saying that the first member 1 and the second member 11 are integrated. Even when the mounting component 21 is removed from the panel 23, it is possible to perform the integration work or the removal work in two directions by arbitrarily selecting the pair of guide holes 14, so that it is possible to compare with the conventional one. Then, the workability becomes extremely good.

In the above embodiment, the large-diameter flange 3 and the small-diameter flange 4 are used as the holding means for the mounting part 21 provided on the shaft body 2 of the first member 1. The holding means is not limited to the above, and other known holding means can be used. In addition, the first member 1 holding the attachment component 21 and the second member 11 engaged with the attachment hole 24 of the panel 23 are not integrated from the beginning with the first member 1 and the second member 11. It is needless to say that even if they are integrated later, a clear feeling of moderation can be obtained as in the above-mentioned embodiment.

[Advantage of Invention] As described above, according to the present invention, one of the guide holes formed on both sides of the through hole of the second member is selected, and the lock shoulder portion on the first member side is provided in the guide hole. When inserted, first, the shaft body of the first member tilts in the guide hole and the through hole while bending the spring arm piece existing on the guide hole side inward by the restricting action of the inclined surface portion with respect to the lock shoulder portion. When the lock shoulder passes through the guide hole, the shaft body is stored vertically in the through hole due to the spring pressure of the spring arm piece that has been bent inward until now. At the same time, the lock shoulder portion of the shaft body automatically engages with the opening edge of the lower end of the through hole with a clear click feeling, so that the first member and the second member are immediately integrated. Not only will the workability be extremely good, , There is no fear of the first and second members being integrated in a defective state.

Further, according to the present invention, even if the shaft side of the first member protruding downward from the main body of the second member is pressed in any direction of the pair of spring arm pieces, the spring arm exists in the pressing direction. Since the piece bends inward and the locking of the lower end opening edge of the through hole of the lock shoulder can be released, it is possible to freely remove the mounting part from the panel in two directions. , Its workability is also extremely good.
