Description Spring hinge for glasses

The invention relates to a spring hinge for glasses with a first one to be attached to the temple arm Hinge leg and a second hinge leg to be attached to the front part of a fitting for the spectacle lenses, the one with the first hinge leg through the hinge eye a hinge pin is connected, and with a spring that is able to urge the temple onto the lens frame

The invention has for its object to provide an improved spring hinge which the bracket over the normal position of use also allows spreading to adapt to the head of the wearer and also ensures that the glasses is held firmly in place »

To solve this problem, the hinge according to the Invention a slider which is firmly attached at one end to the first hinge leg, while its other End forms a flange which extends in the opposite direction to the first hinge leg, one in the longitudinal direction extending housing which is arranged in the bracket and is suitable for receiving the slider and a longitudinal movement of the slider allows so that the first hinge leg extends on the inner surface of the bracket, wherein im Housing a side notch is formed, a fluff spring in a meander shape, which dee between the slider and the bottom Housing and is arranged parallel to it and one end of which

rests against the plan of the slider, while the other end is anchored in the lateral notch of the housing, so that the spring is compressed when the bracket spreads beyond its normal position of use, creating a force which tends to close the bracket and to the head due to the action of the spring on the slider of the wearer ",

If the spring hinge is used with metal brackets, the housing has a longitudinal slot on the inside of the The bracket is closed by a fixed cover plate in which a recess is formed at one end, through which the first hinge leg can extend »

If the spring hinge is used on brackets made of plastic that have a reinforcing core, the housing a flat, U-shaped part, which is attached to the reinforcement core is firmly attached and has a recess at one end through which the first hinge leg can extend, where the part mentioned is fully incorporated in the bracket »

The invention is explained below with advantageous details based on schematic drawings of various exemplary embodiments explained in more detail. It shows:

on a plastic bracket with a spring hinge device in the normal open position of the bracket, whereby also a portion of the eyeglass frame is shown;

Pigβ 5 a side view of the bracket according to Pig «4» wherein the part forming the spring housing is shown partially in section and the temple of its glasses Inside up to the reinforcement core has no plastic;

Pig. 6 is a view similar to Pig. 5 »in which the part is shown in full;

Pig β 7 & en section along the line VII-VII according to Pig. 4 _f in which only the bracket is shown;

Pig, 8 a view similar to Pig. A ₉ in which the maximum spread position of the bracket is shown beyond the normal position of use.

The invention is equally applicable to metal bracket 1A and to plastic bracket 1B for the same purpose and essentially has a first hinge leg 2, which is assigned to the temple and via a pin is connected to a second hinge leg 3, which is attached to the front part 4 of the spectacle frame »The first Hinge part 2 is firmly attached to a flat slide 5 and over this slide a flat peder 6 in Meander shape assigned »Spring 6 and slider 5 are accommodated in a housing in the associated bracket.

In the pail of the metal bracket 1A, the housing has a slot 7 _; which is cut in the longitudinal direction into the inside of the body 8 of the bracket »Peder 6 and slider 5 are arranged in the sole seat 7 and at the same time covered by a fixed cover plate 9» In the front end of the cover plate 9 a recess 10 is formed, the lugs 11 of the first Hinge leg 2 receives the

also has an eye 12 for the hinge pin 13, which the connects the first hinge leg to the second hinge leg 3, which extended away from the slot 7

The spring 6 is parallel between the slider 5 and the bottom of the slot 7, so that one end 14 of it a downwardly bent end flange 15 of the slider rests, while the other end 16 in a lateral notch 17 of the slot 7 formed in the body 8 is inserted "

In the case of the plastic bracket 1B, the housing for the spring 6 and the slider 5 a flat, U-shaped part 18, which on the reinforcing the plastic body 20 of the bracket Metal core 19 is firmly attached «, The U-shaped part 18 arranged on the inner surface of the plastic bracket 1B has in its front end has a recess 21 for the first hinge leg 2 as in the case of the cover plate already described 9 ο

Part 18 as well as the slider and the other elements are dimensioned so that the part 18 is completely in the body of the bracket can be included, even if this has the normal thickness »Such a dimension also ensures that the distance between the axis of the eye 12 and the outer surface of the temple is the same as that of conventional glasses temples »

The spring hinge according to the invention works as follows «If the brackets are spread by hand, reach they first the normal position of use, which is shown in Figo 4, in which the hinge in conventional Way acts without the sliding piece 5 is moved relative to the housing · If the pressure on the bracket is maintained and the Bracket Spread beyond the normal division of use is, it can reach the maximum position shown in Fig. 8, in which the head 5a of the slider 5 at the edge 4a

of the front part rests, whereby a maximum compressive force is exerted on the spring 6 and a maximum displacement of the slider 5 is achieved within the housing «The slider 5 strives, however, under the action of the spring 6 to take the normal position of use according to FIG. 4 again O

Therefore, the wearer can put on his glasses correctly, because he can achieve a width that is slightly larger is than necessary for his head, which makes the process easier. "Then the brackets are released so that they adapt to the head of the wearer by itself, which happens at this moment under the spring action of the spring hinges « The spring hinges also exert a slight pressure against it the head of the wearer to hold the glasses in place, which is a position between that shown in FIGS. 4 and 8 positions shown corresponds to

This embodiment of a spring hinge is economical, light in weight and thin, it avoids Screws, pins and stops, as are provided in similar known constructions. Furthermore, the spring hinge according to the invention has the advantage of being attached to the temples of glasses made of metal and plastic adaptable su βein, wob ·! dl « Plastic hangers can have a long or short metal wire core »A core is denoted for each short core» which only extends over the length of the hinge arrangement In this case, the metal core 19 would be a short flared one Wire, in both cases is arrangement and apportionment simply · Another feature is that the adjustment of the stroke of the spring by means of appropriate adjustment the length of the slider 5 is achieved, the head 5a of the slider on the front parts dor from the edge 4a Eyeglass frame formed stop at different * stroke is present. A high feature is that the Htihe Cos

Hinge is kept within the normal limits for conventional hinges in view of the dimensions of its components, so that the optician can attach eyeglass temples with standard hinge or spring hinge to the same front part of an eyeglass frame at the customer's request, which enables him to keep a smaller stock of eyeglass frames _{or the like}
