Abstract

(57) [Summary] A vine (3) of eyeglasses is articulated on a side member (2) of an eyeglass rim (4) of an eyeglass frame so as to be rotatable around a rotation axis (13), and is opened by a magnetic force. Is provided with at least a pair of magnetic force elements (6a, 6b; 7a, 7b), which pair is arranged outside the rotation axis (13) so as to be parallel thereto, and one element is a vine. Within, the other element is arranged on the side member (2) of the spectacle rim of the corresponding spectacle frame.

Description

DETAILED DESCRIPTION OF THE INVENTION

The present invention relates to a spectacle frame in which a temple is articulated to a rear portion of a side edge of the spectacle frame so as to be pivotable via a rotation axis, and an open state thereof is fixed by a holding force due to magnetic force.

[0002] Spectacle frames of this kind are described in EP 0 522 594 A1 and US Pat. No. 5,682,222 A. It describes several magnetic elements for fixing the temple in the open position defined by the stopper.

[0003] In contrast, an object of the present invention is to facilitate the handling of eyeglasses, and in particular to allow both vines to be opened with one hand.

[0004] The object is achieved according to the invention by the features of claim 1.

The fixing of the two vines in the open position, which is somewhat close to non-contact, according to the present invention, causes both vines to move outwardly toward their open position by light centrifugal action, where the action of the holding force by the magnetic force is applied. Can be fixed by Here, a stopper element for fixing the temple to the open position is not required. On the contrary, this type of stopper can be a hindrance because incorrect handling can return to the semi-open state from the fixed position. In order to minimize as much as possible the movement between the closed and the open state of the temple, it is advantageous to reduce the friction of the rotating shaft, ie the frictional force on the rotation of the temple, as much as possible. Unlike conventional eyeglasses, which require rotational friction to prevent spontaneous closing when the temple is not needed, the temple frame of the present invention can be pivoted as smoothly as possible. The holding force by the magnetic force has an advantage that the holding is achieved so as not to deviate from the holding position in both the turning directions.

Here, according to the present invention, it is particularly preferable that the temple is configured such that a holding force by a magnetic force is applied to both the open position and the closed position of the temple. Thus, the vine is prevented from being opened by vibration; it is released from its fixed state in its closed position by a lighter pivoting action, and is further restrained in its open position by the magnetic field lines between the appropriate magnetic force elements and fixed in its open position. To reach.

It is sufficient for only one of the pair of magnetic elements to be formed as a permanent magnet, and for the other, for example in the case of metal eyeglasses, an eyeglass frame material capable of magnetizing one of the metal eyeglass components Or another element embedded in the spectacle frame can be formed of a magnetizable material.

The subclaims set forth other forms or modifications of the invention.

Next, embodiments of the present invention will be described with reference to the accompanying drawings.

FIG. 1 is a plan view showing a part of a turning axis of the opened eyeglasses, which includes an eyeglass lens 1, a side member 2, and a temple 3. This is a metallic spectacle consisting of a precision metal spectacle rim 4 surrounding a spectacle lens. As a rotating shaft 13 for rotating the temple 3 of the spectacles, an articulated rod 5, in particular a screw, acts; the temple 3 of the spectacles comprises two pairs of magnetic elements 6 a, 6 b which are arranged opposite to the articulated rod 5. And 7a, 7b
In its open position. One of these magnetic force elements 6a, 7a
Are disposed in the receiving holes in the temple 3 respectively, and the elements 6b,
“b” is disposed at a corresponding position in the side member 2. Magnetic element 6a, 6b or 7
a, 7b each extend up to the partition between the side member 2 and the temple 3, so that they are joined in a gas-tight manner, so that a maximum holding force is achieved.

FIGS. 3 and 4 show enlarged magnetic elements arranged similarly to the embodiment of FIGS. 1 and 2. FIG. Here, the magnetic force elements 6a, 6b or 7a, 7b are embedded in the side member 2 or the vine 3 so as not to be seen from the outside. Between the two pairs of magnetic elements a threaded articulation rod 5 is arranged, the neck 8 of which extends through the bore of the temple 3 and which is adjacent to the neck 8 of the temple. Part 9 is neck part 8
Is screwed into the screw hole 10 of the side member 2 such that the front surface 11 of the side member 2 is joined to the opposing surface of the side member 2. In this joined state, there is a very small gap between the upper and lower magnetic elements, which keeps the vine 3 from pivoting so as not to contact the side member 2.
