Description

"Fixing clamp for Christmas tree candles"

The invention relates to a fastening clip for Christmas tree candles, consisting of two clamp legs made of plastic, which are connected to one another via a pivot axis and can be given away against one another against the action of an expanding spring are, wherein the expanding spring acts on the opposite leg ends on one side of the pivot axis and so presses the leg ends lying on the other side of the pivot axis against one another.

In a known embodiment of such mounting brackets, the pivot axis consists of two bearing journals which sit on two tabs of one leg of the clamp and insert them into the corresponding Recesses protrude from the tabs of the other clamp leg. The spreading spring is made of metal and is between the both clamp legs inserted. The previously known mounting brackets thus consist of at least three individual parts.

The invention is based on the object of improving the fastening clip explained at the beginning with regard to its manufacture.

This object is achieved according to the invention / that both KlaÄinier leg, swivel axis and expanding spring together through one one-piece synthetics are formed.

It is advantageous if the section forming the expansion spring of the plastic part is V-shaped, the Ends of the V-legs directly to the be ^ of the expanding spring Connect the opened leg ends.

The pivot axis can consist of a pin, which on its one long side via a web or the like. one piece with the formed a clamp leg and on its opposite the longitudinal side of a bearing shell-shaped section of the other Clamp leg is releasably overlapped. It is advantageous to if the bearing shell-shaped section forms an arc of a circle of slightly more than 180 ° in cross section and so the Snap grips around the pin in a spring-elastic manner.

Great stability can be achieved if each clamp leg consists of an upper and a lower flat side, which are connected to one another via a longitudinal center web.

To mount a Christmas tree candle in a simple way with the To be able to connect the fastening clip, it is expedient if, in the case of the latter, the leg end opposite the expanding spring of the one clamp leg perpendicular to the outer surface thereof running, annularly arranged spring tongues for clamping the clamping ball of the holder of a Christmas tree candle. In order to maintain a pleasing shape, it is advantageous to when the spring tongues sit on the lower flat side of the clamp leg and move upwards into a round recess of the protrude upper flat side. The round recess is chosen so large that the free upper ends of said spring tongues when pressing in the clamping ball of the holder of a Christmas tree candle can move radially outward.

The fastening clip is preferably manufactured as an injection-molded part from acetal resin. Only after the ¹ Preparation of the mounting clip forming part of the one-piece plastic snap lagerschalenformige portion is pressed uniformly over the lying adjacent pin so that the pivot connection is made between the two clip legs. During manufacture, the two clamp legs are approximately parallel to one another. '

Other features of the invention are the subject of the suban ^ - sayings.
