Abstract

clamping spring (1) with a longitudinal direction extending spring leg (1 a) and extending transversely to this Mounting part (1b), for attachment to a temple (2) a collapsible glasses, characterized in that the Clamping spring (1) on the eyeglass temple (2) is festkeilbar.

Description

The The invention relates to a clamping spring with a longitudinal direction extending spring legs and extending transversely to this Mounting part, for attachment to a temple of a collapsible glasses.

In the utility model 202007009346.2 filed on 3.7.2007 already a pair of glasses with detachable attachable clamping spring together with various embodiments proposed for this purpose but where (except according to the execution Claim 7) still changes required on the temples are. Also the execution according to claim 7 fits only a limited number of eyewear models. The present invention is therefore based on the object, more To create clamping springs of this kind, simple and firm, without any an impairment or change on the glasses on a temples attachable, so that practically for each pair of glasses at least one Clamping spring available stands.

This is according to the invention in principle achieved that the clamping spring is festkeilbar on the eyeglass temple; such Wedge connection can be diverse, be adapted to the respective glasses.

Of the Users can easily mount such a clamp spring at any time Temple of his Attach or replace glasses without any damage or change on the glasses.

It There are many eyewear models where the width of the temple is in the direction of on the hinge increases; an inventive clamping spring for this Glasses is characterized in that the fastening part in essentially the shape of a sleeve whose inner circumference corresponds to the outer circumference of the bow in the Area of the hinge corresponds, and the one on its underside Section has, the width of the width of the eyeglass temple its hinge-remote area corresponds (claim 2).

This Fastener attaches to the narrower area of the stirrup put it on and then move it in the direction of the hinge and at the temple wedged.

at Glasses with substantially constant cross-section of the eyeglass temple, however The fastening part is in the form of a sleeve, preferably one has lateral cutout for the insertion of the eyeglass temple and whose inner circumference corresponds to the cross-sectional shape of the bracket, wherein a Wedge for insertion between mounting part and eyeglass temple provided is (claim 3).

It But there are many eyewear models with very different forms of Cross section of the stirrup. Around clamp one and the same clamping spring on each of these different temples to be able to further proposed that the inner circumference of the fastening part the cross-sectional shape of the largest to clamped stirrups Corresponds to the width of the push-through cutout to the smaller cross-sectional dimension of the largest zuklemmenden bracket corresponds, and that the wedge in his thicker area so thick is that with him even the smallest / thinnest bracket in the attachment part is festkeilbar (claim 4).

Preferably is the wedge through the lateral cutout, ie in the transverse direction, in the clamping position, i. displaceable into the operating position (Claim 6).

This elongated, sleeve-shaped fastening part So represents a safe, solid abutment for the spring leg, so the glasses in a breast pocket of a shirt o. The like. Plugged can be, with the edge of the breast pocket between the clamping spring and the temples securely clamped; the so safely stored glasses can at any time again easily removed for reuse. This clamping spring gives rise to more diverse aesthetic Layout.

Further It is proposed that the fastening part and the spring leg are formed as separate parts, wherein the fastening part facing end of the spring leg as a wedge for insertion between Mounting part and eyeglass temple is formed (claim 7).

One another embodiment Is characterized in that the fastening part in the form of two the temple between themselves, slidable against each other, with their side bars together matching shells is formed, which is connected to their side bars optionally in each one of several positions interlocking Locking teeth, Locking ribs or roughening are provided (claim 8). A better Adaptation to different thickness temple is here achieved by that the shells are wider than the temple (claim 9).

Finally will nor suggested that the spring legs on its inside Means to increase the clamping effect or liability has (claim 8).

Finally, a relatively simple clamping spring is characterized in that the fastening part has a contact surface which fits the eyeglass temple has, to the side of a flexible adhesive tape connects.

to closer explanation The invention will be described below with reference to the drawings described, with the clamping spring - for clarity - each in the on a temples deferred position, that is shown in the position of use.

1 shows - for orientation - a plan view of a pair of glasses with a clamping spring according to the invention, folded.

2 shows the section according to line II in 1 , enlarged, schematic, so a temple with festgekeiltem attachment part.

3 is the section in the direction of arrows III-III in 2 ,

4 shows an embodiment according to claim 3 or 4 in one of 3 corresponding representation.

5 shows an embodiment according to claim 4.

6 shows an example according to claim 8.

The clamping spring according to the invention 1 is provided for releasable attachment to a conventional pair of glasses, the two eyeglass temple 2 by means of one hinge each 3 are hinged to the central part of the glasses.

The clamping spring 1 has - as the clamping spring in a pen - in the longitudinal direction of the bracket 2 extending spring legs 1a at which the hinge 3 facing end of a fastening part 1b is trained.

According to 2 and 3 is the fixing part 1b and thus the wedge-effect clamping spring is attachable to a temple which widens in the direction of the hinge, thus giving a wedge angle alpha. The fastening part 1b has the shape of a to the cross section of the temple 2 adapted sleeve 6 whose side walls 6a enclose between them the same angle as that of the bow, and the inner height of which is equal to the thickness of the bow. The sleeve 6 has on its one flat side of a recess 6b a width such that the bracket fits into this recess at its hinge-remote area. If the sleeve, which has been placed on the bracket at its narrower area, is now displaced in the direction of the hinge, it is wedged against the bracket, with the wings facing each other 6c overlap the edges of the temple.

Often, the cross section of the bracket over its entire length is the same, this is the execution after 4 : The 4 corresponds in principle to the 3 , with the difference that the fastening sleeve - here shoe 7 called - on one side an elongated cutout 7b through which the strap passes 2 from one side into the inner storage room 9 of the shoe 7 can be inserted; now becomes the wedge 8th inserted between the sleeve / shoe and strap, the strap is wedged in the sleeve and then laterally by a bridge 7c secured. Due to the insertion depth of the wedge different thickness bracket can be clamped. The slot / cutout 7b and the inner recording room 9 but the shoe can also be as big as the thickest, largest retractable bracket; Tolleranzen be compensated again by the insertion depth of the wedge.

The Clamping spring can be designed in two parts, with a fastening part and a spring leg are plugged together.

5 corresponds to 4 with the difference that the push-through cutout in the bottom / one flat side of the sleeve / shoe 7b is provided. The width of the clipping 7b corresponds to the thickness of the thickest bracket 2 , the height h of the receiving space corresponds to the largest width of the bracket.

6 is also a schematic cross section, this time by an embodiment according to claim 8.
