This application claims priority to PCT application Serial No. EPO 00/12561, filed Dec. 12, 2000, which claims priority on German patent application Serial No. 19963721.0, filed Dec. 29, 1999. The contents of both of which are incorporated in their entiety.
The invention relates to a plastic clip, for the detachable connection of a trim plate to a support piece, in particular, to the door frame of a motor vehicle. The clip comprises a head piece and an anchoring foot, which may be inserted in an opening in the support piece, and an upper part, for fixing to the trim plate, which may be connected to the head piece in a snap-fastening manner.
Such a clip is known, for example, from DE 43 30 102 C2. With this clip it is considered a disadvantage that the head piece is connected as one piece to the anchoring foot and thus is rigidly mounted. Therefore, with this clip it is impossible to balance variations in tolerance between the fixing sites on the trim plate and the fixing openings in the support piece, if the upper part is rigidly connected to the trim plate.
In order to avoid this disadvantage, the inventive plastic clip is so configured that the head piece has the form of an open cylinder and comprises a central recess, on the edge of which inwardly-projecting support segments are formed. A support plate is provided above the anchoring foot, above which a T-shaped support pin extends. The head of the support pin is of such a size that said pin may be engaged in the central recess, with elastic spreading of the support segments, wherein said segments spring back together after the passage of the pin head and thus are supported on the underside of said head.
For reasons of casting it is appropriate if the head of the support pin at the upper edge is connected to the lower edge of the central recess via thin detachably connected webs. As a result, the two-part clip can be sprayed advantageously in a casting mold and subsequently can be combined into a clip by pressing the support head in the central recess of the head piece. Consequently, another advantage is realized in that the head of the support pin opposite the edges of the support segments can be moved radially to balance variation in tolerance.
Similar to the prior art, the upper part, which may be connected to the head piece in a snap-fastening manner, usually is inserted in a keyhole-like pocket formed on the trim plate. However, because the variation in tolerance is balanced between the head piece and the support pin above the anchoring foot, it is appropriate and, from a production point of view, by all means feasible to integrate the upper part directly with the trim plate.
An inventive embodiment is shown in the drawing and explained in greater detail in the following. In the drawing:
FIG. 1 shows a side elevation of the plastic clip in delivery condition below an upper part which is formed on the trim plate;
FIG. 2 shows a profile of the same plastic clip with an upper part according to line II—II in FIG. 1;
FIG. 3 shows the same clip in assembled condition with pressed-on upper part above the opening of the support piece;
FIG. 4 shows the same clip after insertion in the opening and subsequent removal from the upper part; and
FIG. 5 shows three examples for the radial movability of the head piece to the a to c support pin with assembled clip.
The plastic clip shown in the figures essentially consists of a head piece 1, an anchoring foot 2, and an upper part 3 which is fixed to a trim plate 6 is connectable to the head piece 1 in a snap-fastening manner.
As is indicated, especially in FIG. 2, the anchoring foot 2 is formed by two spring-loaded compressible support legs 17 which are connected to an umbrella-like support plate 10 via a central web 18 and which can be inserted in an opening 5 of a support part 4. As soon as the support plate 10 lies upon the support part 4 and the support legs 17 have passed the opening 5 of the support part 4, the support legs spring apart and attach in a known manner at the rear edge of the opening 5. Any plates, in particular, the door frame of a motor vehicle, can be used as support part 4.
The head piece 1 has the form of an open cylinder with a central recess 7, on the upper edge 8 of which inwardly-projecting support segments 9 are formed which follow the arc of the edge. A T-shaped support pin 11 extends above the support plate 10, the head 12 of which is so dimensioned that said pin 11 may be engaged in the central recess 7, with elastic spreading of the support segments 9.
In the present embodiment, the upper edge 13 of head 12 of the support pin 11 is detachably connected to the lower edge 14 of the central recess 7 via several webs 15 which are distributed evenly on the periphery. As a result, the head piece 1 and the anchoring foot 2 are interconnected as one piece from production to delivery (FIG. 2). These elements are first pressed together by the manufacturer of the trim plate 6 by pressing on of the upper part 3 which causes elastic spreading of the support segments 9 (FIG. 3), wherein the segments 9 spring back together after the passage of the pin head 12 and the edges 16 of said segments are supported at the underside thereof.
As is indicated in FIG. 5 a to c, when engaged, the head 12 of the support pin 11 is radially movable so that the anchoring foot 2 can easily be adjusted to the proper position when inserting said foot in the opening 5 of support part 4.
In the present embodiment, the upper part 3 is integrated with the trim plate 6, i.e., formed as a single piece, and consists of a ring 19 whose edge 20 can easily be directed towards the outside. Correspondingly, the head piece 1 includes at least three detents 21 distributed around the periphery of its upper edge 22 projecting towards the inside that interact with the edge 20 in a snap-fastening manner.
FIG. 3 shows the plastic clip in assembled condition with the snapped-on upper part 3 prior to inserting the anchoring foot 2 in the direction of the arrow “E” in the opening 5 of the support piece 4. FIG. 4 shows the plastic clip which is firmly anchored in the support piece 4, after the upper part 3 has been detached in the direction of the arrow “L,” while the anchoring foot 2 remains in the opening 5 of the support piece 4.
