Profile strips on bodies and devices

Profile strips are used in a variety of ways for covering * sealing or for decorating, especially for bodies and devices. . Your attachment is usually · by A _": pushing or pressing into" space provided grooves or the like on smooth surfaces · the installation of moldings is preferably by means arranged at intervals clips which in bores of the carrier sheet; be anchored made; brackets They enable quick and easy assembly and guarantee a vibration and rattle-proof fastening of hollow profile strips.

The attachment of the hollow profile strips have the disadvantage _s dem.Verschieben or slipping, favored by the driving vibration, not enough to oppose Gleltwiäerstsnd why there z .. B - in the application of staples is usual to provide a clamping member _"9, - which security Guaranteed against any change in position of the profile strip in its longitudinal direction. To secure against displacement, the profile strips can also be locally tacked, glued, riveted or screwed on.

These types of position security require with regard to easy attachment of the profile strips with the help of the clips

a relatively large effort and are time consuming * as a result inhibit a 'faster' audible assembly. at a necessary dismantling and reattachment of profile strips Such securing devices act as a hindrance and are usually used carelessly again.

The present invention aims at eliminating these cumbersome position securing abv instead of the various. Method for securing v-on moldings is _s to let the 'inventively provided spring clip in a position to apply anywhere easily and advantageous. '

This clamping spring for securing the position of profile strips Car bodies and devices are illustrated using two exemplary embodiments explained: - ■

FIG. 1 shows a clamping spring according to the invention for securing the position a profile rubber strip for. Sealing in plan view. ; .

FIG. 2 shows the clamping spring according to FIG. 1, mounted in a rage with an inserted rubber strip in cross section. . ·

FIG. 3 shows another clamping spring according to the invention for Use in conjunction with a decorative strip chamber in plan view.

Figure 4 shows the'Klemmfeder according to Figure 3 in the assembled Condition-together with a plastic bracket with a decorative strip attached to it in cross section.

Figure 5 shows the same arrangement as in Figure 4- »but in longitudinal section. '

The two exemplary embodiments in FIGS. 1 and 3 add the characteristic feature which characterizes the invention. _{Acute-angled claws la, Ib, Ic and Id or 2a r} 2b _s 2c and 2d 'are obtained from a short strip of spring * = · strip steel at its corners through corresponding trapezoidal cutouts on the transverse sides. By appropriate shaping of the strip is achieved _? that the claw tips 1 or 2 protrude from the plane of the central part. As a result, the claw tips acquire the ability to anchor themselves in ¹ deia material to be secured against shifting or slipping and thus to lock the profile strip in both directions of its extension. "_ _ -. ■" .- ■■■ -. ...

The clamping spring according to FIG. 1 is intended * inserted in a groove for receiving a professional rubber strip; to become. For the assembly of the girdle in the courage, a hole is provided in which 2 oppositely protruding spring legs 3a and 3b _} in the middle of the. KLeEm- 'spring are arranged, snap into place. The protruding of the tips of the claws is brought about by simply bending the entire clamping spring strip. Is the profile rubber now pressed into the groove _Γ? so the claw tips 1 hook into the rubber-ein.und prevent any displacement of the rubber band, eifens ₉ by the claw tips la and Ib prevent displacement in one direction and the claw tips Ic and Id in the opposite direction. In Figure 2, the clamping spring of Figure .1 is in cross section, shown with inserted rubber profile.

The clamping spring according to FIG. 3 is intended for use in conjunction with a plastic clip, as it is used for fastening decorative strips. The middle part 4 of the clamping spring is cut out accordingly for this purpose and shaped so that the clamping spring is in the clamp

can insert the base. An even more reliable fastening of the clamping spring to the clamp can be brought about by means of a plug "5" which grips and secures the middle part 4 of the clamping spring when it is pressed into the Klara- ·. "" Mer 6 5 can also be used alone in connection with the bracket 6 _- to achieve increased security against unintentional loosening of the bracket τοπ its carrier. If the bracket is inserted into its predetermined hole in the carrier until it engages ₈ and then the Ornamental strip pushed on - so you can see the tips of the claws press resiliently - against the inside of the-ornamental strip, and thus prevent any change in position decorative strip attached to it ».

Of course, the above-described clamping spring can according to of the invention can also be connected to fastening devices in other ways. For example, the clamping spring on a clamp made of a thermoplastic material can be attached by means of thermal deformation? or it can be riveted or welded onto Jspring steel clips. . ■

Ea. is therefore "generally intended - the clamping spring to secure the position of the profile strip *! · Use in conjunction with fastening _{devices, if necessary 9} " »to create a simple and easy-to-assemble protection against slipping or shifting, which enables quick fastening and · Reliable locking of profile strips guaranteed. The reliable anchoring, which is achieved with the present invention, has the further advantage that only one or a few such clamping springs are required in each case. . · ■. ■ - ...
