Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a mounting device for a radiator grill of an automobile, and in particular provides a mounting device that facilitates the installation and removal of a radiator grill.

[Prior Art] Conventionally, this type of mounting device includes a female member that is fixed in a mounting hole drilled in a panel, and a male member that is inserted and held in the female member that hangs down from the mounting part that is attached to the panel. The female member includes a flange portion that is one size larger than the mounting hole, a body portion that hangs down from the flange portion and fits into the attachment hole, and an insertion hole that is opened in series from the flange portion to the body portion. A device is known which includes a locking means for locking the trunk in the attachment hole in cooperation with the flange, and a holding means for restraining the male member inserted into the insertion hole in the insertion hole. (for example, Mikoaki
57-39625, Special Publication No. 60-12510).

[Problems to be solved by the invention] However, in the conventional mounting device, the male member must be inserted perpendicularly to the insertion hole of the female member.
Furthermore, when pulling out the male member, it was necessary to forcefully pull it out perpendicular to the insertion hole of the female member.

For this reason, there was a problem that it could not be used for something that is mounted from the side within the frame of a body panel, such as a radiator grill.

Therefore, the present invention is intended to solve the above-mentioned conventional problems, and its purpose is to provide a mounting device that allows the radiator grill to be attached and removed while it is tilted diagonally within the frame of the body panel. It is something.

[Means for Solving the Problems] The present invention is intended to achieve the above object, and the contents thereof will be explained below using embodiments shown in the drawings.

The holding means for the female member 6 of the present invention is opposed to each other across the insertion hole 12 in the front and back directions of the radiator grille 1, is connected to the body by a flexible element (for example, the lower end hinge part 16') at the lower end, and is The male member 7 is equipped with a pair of elastic holding pieces 16 each having a free end, and a protrusion 17 protruding in an arc shape from the inner surface of the upper end of both holding pieces toward the insertion hole. a base 18 that abuts against the flange 10 of the panel and holds the radiator grill upwardly apart from the panel (for example, the lower frame 2a of the body panel 2); An insertion leg 19 is provided, and in the middle of the height of the insertion leg, there is an expanded spindle-shaped cross-sectional shape that abuts the opposing protrusions of the holding piece and widens the opposing distance between the holding pieces. 20, and an arc-shaped constricted part 21 located above the expanded part and abuts both protrusions at a position where the expanded part passes under the protrusion.

[Function] First, when fixing the radiator grille 1 to the panel 2a, the insertion legs 19 of the male member 7 should be aligned with the insertion holes 12 of the female member 6 and inserted diagonally from above.

In this way, when the insertion leg part of the male member is inserted, the expanded part 20 of the pair of protrusions 17 projects into the insertion hole.
However, since the insertion leg portion is inserted diagonally at that time, it abuts both protrusions unevenly, and both holding pieces 16 are expanded asymmetrically.

When the insertion leg is inserted deeper, one of the protrusions reaches the arc-shaped constriction 21 from the widened part, and after a short delay, the other protrusion similarly reaches the constricted part from the widened part. Both holding pieces return individually. At this time, the elastic restoring force of both holding pieces pulls the insertion leg of the male member into the insertion hole of the female member, and both holding pieces try to return symmetrically, causing a rotational moment in the insertion leg and causing the male member to The insertion leg of the female member is pulled in substantially perpendicularly to the insertion hole of the female member. When the enlarged part of the male member passes under both protrusions, both protrusions bite into the upper constriction of the enlarged part and frictionally engage with each other, causing the insertion leg of the male member to pass under the insertion leg of the female member. The radiator grille is held in the hole and fixed approximately perpendicularly to the panel.

On the other hand, in order to remove the radiator grille from the panel, the radiator grille may be tilted obliquely in the direction in which it is desired to be removed, against the elastic force of both holding pieces of the female member.

In this way, by tilting the radiator grill,
Since the base 18 of the male member is in contact with the flange 10 of the female member and the radiator grill is held apart from the panel above, the base 18 of the male member is in contact with the flange 10 of the female member. The radiator grille is slanted relative to the panel. With this inclination, the insertion leg of the male member is slightly pulled out from the insertion hole of the female member.
At this time, both protrusions of the female member are pried with the expanded portions of the insertion legs to widen the opposing distance between the holding pieces. When both protruding parts of the female member get over the maximum protruding part 20' of the expanded part of the male member, both holding pieces restore inwardly to each other, and the restoring force causes the insertion legs of the male member to move into the female member. It will be pushed out of the insertion hole and the radiator grill will come off diagonally from the panel.

[Example] The present invention will be described below based on an example shown in the drawings.

In the figure, 1 is a radiator grill, 2 is a body panel having a lower frame 2a supporting the lower end of the radiator grill 1 and an upper frame 2b to which the upper end of the radiator grill 1 is attached, and 3 is a hood.

It consists of a body part 11 that hangs down from the lower surface of this collar part 10 and is fitted into a rectangular attachment hole 5, and a series of insertion holes 12 are opened from the collar part 10 to the body part 11 vertically.

The body portion 11 is arranged along two opposing sides 5a, 5a of the rectangular mounting hole 5, and has both ends abutting the corners 5', 5' on both sides of the two sides 5a, respectively, and is a pair that defines the insertion hole 12. The outer pieces 13, 13 are provided. In addition, mounting hole 5
is a rectangle that is horizontally elongated from side to side with respect to the mounting direction of the radiator grill 1, and the two sides 5a are the short sides.

Each outer piece 13 is provided with locking means for locking the body 11 in the mounting hole 5 in cooperation with the collar 10. This locking means has a U-shaped notch in the upper end of each outer piece 13, is surrounded by this notch, projects diagonally outward toward the lower surface of the flange 10, and faces toward each other across the insertion hole 12. It consists of a pair of tongue-shaped elastic locking pieces 14, 14.

Further, within the space between the two outer pieces 13, there is provided a holding means for restraining the male member 7 inserted into the insertion hole 12 in the insertion hole 12. This holding means is attached to the other two opposing sides of the rectangular mounting hole 5, in this case the long side 5.
b, 5b, and located away from the long side 5b inwardly, both lower ends are connected to the inner surfaces of both outer pieces 13 via connecting parts 15, 15, and are opposite to each other with the insertion hole 12 in between. A pair of tongue-shaped elastic holding pieces 1
It consists of 6 and 16. Each holding piece 16 is provided with a protrusion 17 having a semicircular cross section that protrudes inwardly toward the insertion hole 12 from the inner surface of its upper end.

The upper surface of the opening of the insertion hole 12 is cut in the left and right directions until the upper ends of both the locking pieces 14 face upward.
Opposing convex notches 12', 12' are provided on the front and rear edges of the holding pieces 16, with the upper ends of each holding piece 16 facing upward.

The male member 7 has a circular base 18 that comes into contact with the flange 10 of the female member 6 and holds the lower end of the radiator grill 1 upwardly apart from the upper surface of the lower frame 2a, and is suspended from the base 18, An insertion leg 19 having a cone-shaped cross section is provided which projects into the insertion hole 12 of the female member 7. The insertion leg portion 19 includes an expanded portion 20 which is bulged into a spindle shape and which abuts against the protrusion 17 of the holding piece 16 of the female member 6 and widens the opposing distance between the holding pieces 16, and this expanded portion. 20, and the expanded portion 20 is located above the protrusion 1.
It is provided with an arcuate constricted part 21 that frictionally engages with both protrusions 17 at a position passing under 7.

In addition, in the embodiment shown in the drawings, in consideration of the ease of attaching the male member 7, a rectangular insertion hole 22 is provided at the lower end of the radiator grille 1, penetrating vertically.
A box-shaped head 23 that fits into the insertion hole 22 is integrally provided from the upper surface of the base 18 of the male member 7.
There are U-shaped notches on the left and right outer walls of 3, and the base 18
A pair of tongue-shaped claws 24, 24 are provided that project obliquely outward toward the upper surface. Further, on the upper surface of the base portion 18, an annular elastic portion 25 in the shape of an upward suction cup is provided.

Next, the procedure for attaching the male member 6 will be explained.
You can insert it from above according to the At this time, since the mounting hole 5 is rectangular, the left and right outer pieces 13 are inserted along both short sides 5a, respectively.

In this way, when the body part 11 is inserted from above, both the locking pieces 14 come into contact with the edges of the short sides 5a of the mounting hole 5, are pushed by the edges of the short sides 5a, and are directed from their lower ends to the insertion hole 12. Once bent, the body portion 11 fits into the attachment hole 5. Then, when the upper end of the locking piece 14 passes down the edge of the short side 5a, it returns to its original state with its own elastic restoring force, and the upper end of the locking piece 14 moves downward to the lower frame 5a.
The body 11 of the male member 6 is caught on the lower surface of the male member 6, and the lower frame 2a is held between the lower surface of the flange 10 and the lower surface of the flange 10.
into the mounting hole 5 (Fig. 3).

Furthermore, the procedure for attaching the male member 7 will be explained by aligning its head 23 with the insertion hole 22 of the radiator grille 1 and inserting it from below. In this case as well, the outer surfaces of the mounting hole 5 and the head 23 are made rectangular to prevent the mounting direction from being mistaken.

In this way, when the head 23 is inserted from below, its claws 24 are pushed by the inner edge of the insertion hole 22 and bend inward, and when the claws 24 pass upward through the edge of the insertion hole 22, they return with their own elastic restoring force. The upper surface of the lower end of the radiator grille 1 is caught, and the lower end of the radiator grille 1 is elastically clamped from above and below between the upper surface of the sucker-shaped annular elastic part 25, and the head 23 of the male member 7 is into the insertion hole 22 of the radiator grille 1 (FIG. 3).

Next, in order to attach the radiator grille 1 to the body panel 2, the radiator grille 1 is tilted diagonally, and the insertion leg part 1 of the male member 7 is attached to the lower end of the radiator grille 1.
9 into the insertion hole 12 of the female member 6 attached to the lower frame 2a.
Just insert it diagonally from above.

In this way, when the insertion leg 19 of the male member 7 is inserted obliquely from above, the front and rear surfaces of the expanded portion 20 come into contact with the protrusion 17 protruding into the insertion hole 12, but at that time, the insertion leg 19 Because it is inserted diagonally,
In this case, the protrusion 17 located on the front side with respect to the insertion direction of the insertion leg 19 is strongly pressed, and the holding piece 16 is bent deeply outward from the lower end hinge part 16', and the other holding piece 16 is deflected relatively shallowly (Fig. 13).

Furthermore, when the insertion leg 19 is inserted deeply, both protrusions 1
One of the protrusions 17 reaches the arc-shaped constriction 21 from the widened part 20, and after a little delay, the other protrusion 17 similarly reaches the constricted part 21 from the widened part 20, and both holding pieces 16
will return individually. At that time, the return force of both holding pieces 16 causes the insertion leg part 19 of the male member 7 to be pulled into the insertion hole 12 of the female member 6, and both holding pieces 16 try to return symmetrically. A rotational moment is generated, and the insertion leg 19 of the male member 7 is drawn in substantially perpendicularly to the insertion hole 12 of the female member 6, and the enlarged portion 20 of the male member 7 passes under both protrusions 17.

In this way, the expanded portion 20 of the male member 7
When passing under the narrow part 2 above the widened part 20,
Both protrusions 17 bite into and frictionally engage with 1, restraining the insertion leg 19 of the male member 7 in the insertion hole 12 of the female member 6, and the radiator grille 1 is attached to the upper surface of the lower frame 2a of the body panel 2. Install almost vertically (Figure 14).

Next, the radiator grille 1 is fixed within the frame of the body panel 2 by passing the screws 8 from the upper end of the radiator grille 1 horizontally through the upper frame 2b and tightening them with wing nuts 9 (Fig. 1). .

On the other hand, in order to remove the radiator grille 1 from the body panel 2, first loosen the wing nuts 9 and remove the upper end portion of the radiator grille 1 from the upper frame 2b.

Next, the radiator grille 1 may be tilted forward using its lower end as a fulcrum (FIG. 13).

When the radiator grille 1 is tilted in this manner, the base portion 18 of the male member 7 comes into contact with the flange portion 10 of the female member 6, and the radiator grille 1 is held apart upward from the upper surface of the lower frame 2a. The radiator grille 1 is inclined with respect to the upper surface of the lower frame 2a, using the point of contact between the base portion 18 of the male member 7 and the flange portion 10 of the female member 6 as a fulcrum. With this inclination, the insertion leg portion 19 of the male member 7 is slightly pulled out from the insertion hole 12 of the female member 6.

At that time, the expansion portions 20 of the insertion legs 19 are used to pry both protrusions 17 of the female member 6, and both holding pieces 16
Expand the spacing between the two. Then, both protruding parts 17 of the female member 6 are connected to the maximum protruding part 2 of the expanded part 20 of the male member 7.
0', since the expanded portion 20 has a conical shape, both the holding pieces 16 restore inward to each other, and the insertion leg 19 of the male member 7 is pushed into the female member 6 by the restoring force. The radiator grille 1 is pushed out from the insertion hole 12 and comes off obliquely in the direction of inclination.

On the other hand, 26 is a metal plate spring attached to both holding pieces 16 of the female member 6, as shown in FIGS. Bend each other inward to form a bent part 2.
6' is formed. Further, on the outer surface of both holding pieces 16 of the female member 6, there is a shallow guide groove 2 into which the leaf spring 26 is fitted.
7, and a deep locking groove 28 at the upper end of the guide groove 27 into which the bent portion 26' of the leaf spring 26 is fitted.
will be established.

To install the leaf spring 26, it is sufficient to slightly widen the gap between both ends and fit it from below in line with the guide groove 27, so that the bent part 26' of the leaf spring 26 is elastically inserted into the locking groove 28. By fitting, the leaf spring 26 will not come off (FIG. 16). In this way, leaf spring 2
6, the rigidity of the holding piece 16 of the female member 6 can be increased by the spring force of the leaf spring 26, and the holding force by both holding pieces 16 can be improved. Note that the attachment of the leaf spring 26 is optional.

FIG. 17 shows another embodiment of the present invention, in which the insertion leg 19 of the male member 7 has a multi-stage structure. The insertion leg portion 19 is formed with two stages of enlarged diameter portions 20 and constricted portions 21 alternately from the tip end. According to this embodiment, the mounting height of the radiator grille 1 can be adjusted in two levels. Note that the structure is not limited to two stages, but may be a multi-stage structure.

[Effects of the Invention] As explained above, according to the present invention, it is possible to provide a mounting device that allows the radiator grill to be attached and detached in a state where the radiator grille is tilted diagonally with respect to the panel.
