Description

Device for interchangeable lenses for the interchangeable connection of

Spectacle frame parts

Technical area

The invention relates to a device for changing goggles for

interchangeable connection of spectacle frame parts.

State of the art

Wearers increasingly want glasses, the temple, jaws or bridges can be replaced. On the one hand there is the need in the foreground, change the optical impression of the glasses by changing the eyeglass temple and the glasses thereby vary in design can change.

On the other hand, spectacle wearers increasingly want spectacles with interchangeable temples, jaws or bridges for reasons of cost, which allow easy replacement or replacement in the event of wear and tear or in the event of damage.

Various devices for changing jaws, straps or bridges of a spectacle frame are known from the prior art, wherein various

Embodiments of the devices exist that are specially designed for Randlosbrillen. For glasses with eyeglass frame various devices are known that allow the replacement of the temple.

For example, in these known devices for replacing jaws or shoe straps, carrier elements for supportingly receiving the jaws on the spectacle lenses or on the spectacle frame are defined, which are designed to come into operative connection with, for example, a holding section of the jaws in such a way that the jaws are simply plugged on or slid on can be connected to the support elements with these.

For example, EP 1 877 853 B1 discloses such a device for

Changing of jaws for rimless glasses and for metal and

Plastic eyeglass frames. The device includes a for receiving a Jaw or a jaw strap trained support member which is mounted on the outside facing away from the wearer glasses on the edge of the lens or the spectacle frame. The jaw has a shape and size adapted to the support element recess on the length of the support element, wherein the support member is received in the recess of the jaw. By attaching or pushing the jaw on the support member jaw and support member can be positively connected to each other.

Since adaptation of the design by changing spectacle frame parts, in particular eyeglass temples, is increasingly desired for a wide variety of spectacle models, there is a further need, despite the solutions known from the prior art, to provide replacement systems for interchangeable lenses in which the replacement of the temples can be achieved by a simple connection mechanism safe and reliable works. Such a simple connection mechanism is particularly desirable for spectacle frames with very thin or thin-walled spectacle frame parts.

Presentation of the invention

Object of the present invention is therefore to provide a device that overcomes the disadvantages of the prior art, which allows in particular a material-friendly changing the spectacle frame parts and is low in the production. This object is achieved by the device according to independent claim 1. Further advantageous aspects, details and

Embodiments of the invention will become apparent from the dependent claims, the description and the drawings.

The present invention provides a device for goggles

interchangeable attachment of at least one bracket, a jaw and / or a

Bridge on a spectacle frame or a spectacle lens available. The at least one bracket, the jaw and / or the bridge have at least one free end at least one connecting portion and at the lens or the spectacle frame at least one socket portion is provided with a receiving space for plug-in form-locking reception of the connecting portion. The device is characterized in particular by the fact that the

Connecting portion of the at least one bracket, the jaw and / or the bridge is formed as a flat end portion and has a formed by means of an embossing latching lug and in that the plug-in sleeve portion has a corresponding latching recess, wherein the latching lug is received in the latching recess in the connected state latching.

The present device can be understood as a replacement system for spectacle frame parts, wherein at least the brackets of the spectacle frame can be replaceably attached to the spectacle frame or the spectacle lens. Both

Interchangeable ironing can be called a "baking hanger" or

Hinge handle act, which have at least one articulated with a jaw portion bracket section. Alternatively, the hangers can vary depending on

Implementation and depending on which material they are made, even without a hinge. The change system can therefore be equally for

Rimless eyeglasses as well as for glasses with a trained as a partial or full frame glasses frame use find. In particular, the present device is suitable as a replacement system for spectacle frame parts in very thin spectacle frames.

In the inventive device for interchangeable attachment of the bracket, the jaw and / or the bridge, a free end of the bracket, the jaw and / or the bridge is in the form of a flat end portion, which forms the

Connecting portion for releasable attachment to spectacle lens or spectacle frame forms. On the spectacle lens or the spectacle frame, a receptacle section is further provided, which provides a receiving space for insertable and positive reception of the connecting portion available. The receiving space of the receptacle section is particularly advantageous in shape and size of the

Adjusted connecting portion and can be understood in the present case as essentially slot-shaped receiving space.

According to the invention, a locking nose is formed in the connecting portion of the bracket, the jaw and / or the bridge, which is adapted to engage in a provided corresponding recess in the socket portion. In the connection state, the latching lug is latched in the latching recess. The locking lug of the connecting portion is formed by means of an embossing in the material of the flat end portion. Under a locking lug formed by embossing is understood herein that the locking lug is formed by forming in the flat end portion or in the material of the flat end portion by means of a stamping or forming tool and thus impressed. The detent thus represents a relief in some ways. Particularly advantageous is the production of ironing, jaws and / or the bridge with a connecting portion as described herein simple and inexpensive. Furthermore, a detent formed by embossing proves particularly in narrow, very thin or delicate spectacle frame parts to be particularly advantageous.

The present, formed by an embossing latch can thereby

particularly advantageously have a slight spring action, so that in a particularly gentle way, a slight engagement of the locking lug in the recess and a sufficiently strong locking can be effected. However, the embossed latching lug allows a secure mounting of the spectacle frame parts when the latching lug is in the locked state. Further advantageously, the latching can be released again by the action of a corresponding tensile force, wherein a slightly resilient effect of the latching lug formed by embossing also causes a material-gentle release. The

However, replacing the spectacle frame parts and secure holding the spectacle frame parts can also be ensured by a solid, non-resilient locking lug. Preferably, at least the connecting portion of the at least one bracket, the jaw and / or the bridge made of metal. The locking lug is particularly preferably embossed by means of pressure forming in the flat end portion of metal. At a front side of the flat connecting portion while a recess is formed and the latch protrudes on a rear side of the flat

Connecting portion beyond a rear surface of the connecting portion. For example, the locking lug by means of a punch or a

Punziereisens introduced into the metal of the flat connecting portion.

In rimless eyeglasses, the receptacle sleeve portion for insertable receiving the connecting portion as a directly connectable to the lens

Plug sleeve element may be formed. The receptacle element is included

preferably made of plastic and has at least a first

Fixing pin for engaging in a bore, preferably one

Through hole in the lens on. With the help of engaging in the hole in the lens mounting pin and with the help of a cooperating with the fixing pin fixing means, such as a locking screw or a nut, the socket element can be directly and directly fixed to the lens, wherein the socket element on a the face of a Eyeglass wearer facing away from the front or outside of the lenses is attached.

The at least one fastening pin is preferably formed on the socket element. Particularly preferred is a fastening pin made of metal, for example a threaded pin with a socket anchored in the socket element, wherein the fastening pin is very particularly preferably poured in the manufacture of the socket element by injection molding in the plastic. In order to ensure a firmer and more secure hold of the receptacle element on the spectacle lens, in particular in order to achieve a torsion-proof determination, special advantages result from the fact that in addition to the at least one

Fixing pin another positioning pin or attachment pin on the

Plug sleeve element is provided, which can engage in a further bore, in particular a through hole or a recess, for example a blind hole in the lens.

The latching recess of the socket element is in the form of an opening or a through hole. The opening or through hole of the

Steckhülsenelementes is in a state attached to the lens of the

Plug sleeve element facing the spectacle lens. In a front view of the glasses or in front view of the glasses so that neither the opening or

Through hole trained recess still visible in the locking recess detent latching visible, since both the recess and the locking lug are facing the lens and thus the face of a spectacle wearer.

In spectacles with a frame frame designed as a partial or full frame, the socket section is provided by means of the spectacle frame, wherein the

Reception room for plug-in form-fitting recording of the

Connecting portion is integrated in the eyeglass frame. Particularly preferably, the receiving space is arranged in a lateral section of the spectacle frame. For example, the integrated in the eyeglass frame

Recording space may be formed by injection molding, and indeed during the manufacture of the spectacle frame.

Further developments, advantages and applications of the invention will become apparent from the following description of exemplary embodiments and from the figures. All described and / or illustrated features are for itself or in any combination in principle subject of the invention, regardless of their summary in the claims or their

Dependency.
