Description

Glasses and glasses

The present invention relates to an eyeglass and an eyeglass frame therefor, and more particularly to a lens that uses a screwless pivot to the eyeglass frame.

Screw-less hinges or joint mechanisms for glasses having different configurations are known. For example, European Patent No. EP 863 424 discloses a pivot mechanism for eyeglasses, the eyeglass frame comprising three leaf springs arranged substantially parallel and made of sheet metal, one of the leaf springs and one of the frames A connecting element cooperates to form a joint. Based on this, the outer leaf spring is guided along the side of the connecting element, which faces the face of the wearer of the eyeglass when wearing the eyeglass, before which each also passes through two slits in the connecting element a slit-like recess, the notches being vertically arranged on each other, having a bent section bent in one of the free-sliding manners and having a free end thereof connected to the side of the connecting member, the side facing Stay away from glasses wearers. At the same time, the intermediate piece spring supports against the side of the connecting element which faces away from the face of the wearer of the eyeglasses. When the eyeglass frame rotates, the outer leaf spring does spread apart relative to the intermediate leaf spring, thus creating a spring effect, thereby supporting the folding-in and folding of the eye stand. (folding-out) action.

However, it is known that the shortcomings of the connection of the glasses are based on stability. The reason of the reason, which cannot be lower than some minimum size. In the case of a very small piece of spring, there is a risk when the temple is rotated, the outer leaf spring cannot be guided in a sufficiently secure and stable manner in the vertical recess of the connecting element, and the coupling mechanism may be distracted. Among them, very small pieces of spring occasionally tilt up or down. Furthermore, some size leaf springs will become unable to achieve a spring effect, which is still substantially large enough to support the folding and folding process of the lensless joint function of such glasses. .

In view of the above, it is an object of the present invention to provide a novel screwless eyeglass connection for eyeglasses that allows for sufficient stability with respect to the folding and folding action of the eyeglass frame, although the pivoting part is implemented Very small size.

This object can be achieved by the eyeglass frame described in claim 1 of the patent application and the spectacles described in claim 10 of the patent application.

According to a first aspect, in general, the invention relates to a spectacle frame comprising a first temple end made of sheet metal at its pivotal side end (hinge -side end), the first tripod end defines a first plane, and further includes a second temple end made of a metal plate at its pivotal side end, The second leg end defines a second plane, wherein the second leg end is disposed relative to the first leg end, such that in the assembled state of the spectacle front lens frame, A spring effect between the tripod end and the second tripod end causes the spectacle frame to rotate, and wherein the second leg end is oriented relative to the first leg end, such that The second plane is perpendicular to the first plane.

The invention is characterized in that the first tripod end comprises a recess and the second tripod end comprises a section, the recess and the section being configured in such a manner that the section is substantially completely connected into the recess. That is, when the eyeglass frame is in a folded-out state, it extends along the longitudinal direction of the entire temple.

More preferably, the temple is made of flat metal, such as a spring sheet. Based on the fact that one of the planes of the first tripod end is oriented to traverse the other plane of the second tripod end, a very stable, jointless mechanism can be formed, which will be detailed later. . Therefore, the thickness of the metal spectacles, particularly the spectacles material, and the thickness of the front side or the frame of the spectacles can be further reduced. The overall size of the hinge mechanism can be chosen to be very small, and the extension of the eyeglass frame across its longitudinal extension can be configured to be very small, thereby achieving a very lace-like filigree. glasses.

According to another aspect, the invention relates to a spectacles comprising a frame or a spectacle front having a connecting element on the left and right sides, respectively, for rotating support of the spectacles ( Swiveling support).

In a first embodiment, the eyeglass frame according to the present invention includes a recess adjacent to the first leg end which extends in the longitudinal direction of one of the eyeglass frames, preferably just in the a horizontal center of the first plane defined by the first tripod end, including a dimension that enables the section of the second tripod end to be coupled into the recess such that when the spectacle frame is folded (folded-out), the temple is stable with respect to tilting motion across one of its longitudinal extensions.

With regard to this stabilizing effect of any possible tilting motion, the direction is oriented to extend across the longitudinal direction of the stand and also across the definition of folding-in motion and folding-out motion. One plane is formed, so that the section of the second tripod end according to the present invention can be realized as a counter-abutment when it is coupled with the groove of the first tripod end, The edges of the grooves are indeed supported along their horizontal length, that is, in the longitudinal extension of the temple, making rotation of the temples possible.

According to another embodiment of the present invention, the bipod ends are formed as leaf springs disposed opposite each other such that the first leg ends extend relative to the second leg ends during rotation of the temples (spreads apart), thereby creating a spring effect between the ends of the tripod, which acts on the plane of the rotating motion, and thereby supports the folding and folding process of the temple.

For this purpose, the second leg end is fixed to a surface of the eyeglass frame that faces the face of the wearer of the lens, preferably by a correspondingly formed connecting element, such as a snap element (snapping) Element) is locked to the opening of the temple.

The joining mechanism according to the present invention is completed by the connecting elements of the first leg end and the second leg end cooperating frame, and will be realized as follows.

The second leg end includes a device that is configured to form a rotating mechanism with a complementary device at the connecting element at the front of the lens.

According to a preferred embodiment, the connecting element can comprise a vertical web (web) or a pillar (strut). Conversely, the second leg end may include a corresponding outer recess that cooperates with the web to form a rotating mechanism, the inner edge of the recess being at least partially coupled to the web, and the rotational movement of the eyeglass frame (swiveling motion) slides around it. Therefore, the recess may be configured to have a hook or the like having a hook portion whose opening faces away from the connecting member, and the border of the hook portion faces outward, that is, when the eyeglass frame is in a folded state The time is toward the front of the eyeglasses, and when the eyeglass frame is in a folded-in state, it is toward the connecting element, and indeed the web is encased with a rotatable support.

The web or struts may be formed as a separation between two recesses of the connecting element, the two recesses extending lengthwise in the direction of alignment and in the direction of the spectacles. During the rotational movement of the temple, the different portions of the edge of the hook pass through the two notches. Since the edge is formed substantially in a planer way based on the traverse position of the second tripod end, the corresponding flat section of the edge does slide over the recess of the connecting element and remains in the recess Sufficient support, based on its planar and flat extension, causes a tilting movement of the temple to be counter-acted as the rotation extends across its longitudinal extent.

According to a preferred embodiment of the present invention, the edge of the hook-shaped recess at the second leg end can be further configured such that when the eyeglass frame is in the folded-out state, the edge can substantially completely fill the two notches of the connecting member, however Still allowing a full rotation of the rotary motion.

According to the invention, the rotating hinge formed by the edge of the hook-shaped recess includes a section which is connected to the groove of the first leg end, the recess The groove is preferably extended in the horizontal direction.

In order to achieve a stable pivot or linkage mechanism, the present invention further provides a section at the edge of the recess of the second tripod end, the horizontal recess of the first tripod end receiving the section, where applicable, the connecting element The notches are also configured and rotated relative to one another such that when the spectacle frame is folded, a tilting movement across one of the longitudinal extensions of the spectacle frame can be prevented, while the segment of the edge is joined to the first leg The groove of the end, as abutting as one of the edges of the groove, when a force that happens to produce a tilting torque is applied to the eyeglass frame across the length direction from above or below, this force will result The edge of the groove does make contact with the section of the edge.

Through the realization of this linkage mechanism, not only can a lens holder be provided with a very small size in the longitudinal direction, but also can be guided in a stable and special anti-tilt manner during folding and folding, that is, during wearing glasses. And support, regardless of its filigree configuration.

The spectacles according to the invention comprise a spectacle front or frame 1 for accommodating the glasses of the spectacle. A connecting element 2 is provided on both sides of the frame 1, and more preferably integrated therewith, which is oriented substantially toward a spectacle temple 3 when it is in a folded state (folding- When out), especially as shown in Figure 1b.

In particular, as shown in Figures 4a and 4b, the eyeglass frame 3 according to the present invention includes a first temple end 4 and a second temple end 5 at its joint side end ( The area of the joint-side end, that is, the part thereof, faces the connecting element 2. The first tripod end 4 and the second tripod end 5 are made of a flat material, such as a sheet metal, which preferably includes the same material thickness.

Therefore, the first tripod end 4 is disposed on the outer side, that is, facing away from the face of the wearer of the glasses, and the second tripod end 5 is disposed on the inner side, that is, facing the face facing the wearer of the glasses, It can be clearly seen in Figures 2a and 2b.

Thus, the first tripod end 4 defines a first plane E1 and the second tripod end 5 defines a second plane E2.

One feature of the present invention is that the second leg end 5 is disposed and oriented relative to the first leg end 4 such that the first plane E1 is substantially transverse, and more preferably perpendicular to the second plane E2. Figure 4a shows a plan view of the first plane E1 of the first tripod end 4 viewed from the inside of the spectacle frame 3, and Figure 4b shows a plan view of the second plane E2 of the second tripod end 5, along the 4a The section line AA of the figure is cut into the anterior area.

The first tripod end 4 includes a recess 6 that extends parallel to The longitudinal extension of the temple 3 is in the middle of its first plane E1. The recess 6 is provided to pass unobstructed or to the second leg end 5 at certain locations. Thus, the second tripod end 5 is correspondingly oriented and disposed relative to the first tripod end 4, corresponding to its size, state, position, and extension.

Further, the second tripod end 5 is oriented relative to the first tripod end 4 and configured such that when the spectacle frame 3 is rotated relative to the connecting element 2, a spring effect will be generated which can support the temples The folding-in and folding-out processes of the frame 3, while the second leg end 5 is spread apart relative to the first leg end 4, such as Figures 2a through 3b are also clearly seen from Figure 7a regarding another embodiment.

Therefore, the first tripod end 4 and the second tripod end 5 are substantially designed as a leaf spring, wherein the second tripod end 5 is fixedly mounted on the inside with a section, that is to say The side of the eyeglass frame 3 faces the face of the wearer of the glasses. The section of the second tripod end 5 preferably includes a nose-like snap element 7 that fits into the corresponding opening 8 of the surface of the temple 3. It won't loosen. This opening 8 has the same height as the groove 6 and follows the groove 6. Other joining mechanisms such as soldering are also applicable.

Based on the configuration of the eyeglass frame 3 and the glasses, respectively, according to which the second leg end 5 is configured to be substantially perpendicular to the first stand end 4, or the second plane E2 thereof corresponds to the first plane E1, thus The eyeglass frame 3 is designed to provide the required support spring effect, and under this connection, the joint mechanism at the connecting member 2 is therefore very small, but still largely Stable, as explained below.

Therefore, the hinge mechanism according to the present invention can be realized as follows.

As shown in Fig. 5, the connecting element 2 comprises two recesses 9.1, 9.2 arranged in the middle and aligned with each other with respect to the longitudinal extension of the connecting element 2, the two notches 9.1, 9.2 being transmitted The webs 10 are separated from each other.

At the free end facing the connecting element 2, the second leg end 5 comprises a recess 11 which is shaped as a half-open eyelet or loop and thus formed as a hook (hook).

In the assembled state, the hook or hook-like recess 11 surrounds or surrounds the web 10 from the inside of the connecting element 2, that is to say facing the wearer side of the lens, so that the second leg end 5 can be wound around the web 10 Rotating, where the web 10 is actually used as a stationary rotational axis (see Figures 3b and 7a).

At this time, the first tripod end 4 is guided on the outside of the connecting element 2, that is, facing away from the wearer side of the lens, in a slidable manner. When the eyeglass frame 3 is in the folded-out state, the first tripod end 4 on the outer side is planarly attached to the connecting member 2, as shown in Figures 1a, 1b and 6, and when the eyeglass frame is folded When folding-in, as shown in Figures 2a and 3b, the first tripod end 4 is turned over (topple or slide) facing the side edge of the temple 3 ) 12 (see Figure 5).

Extending across the longitudinal direction of the first plane E1, the first tripod end 4 includes a taper 13 which is achieved by reducing the width at the corresponding position, more preferably as seen in Figure 2b. First tripod end 4 to connecting element 2 The side small edge 12 is guided by the wedge portion 13 , wherein a U-shaped guide is additionally formed for the two protrusions 14 of the edge 12 for the wedge portion 13 so that the first The tripod end 4 does not traverse the swiveling direction when the spectacle frame 3 is swiveling motion, thus imparting an additional stability to the attachment mechanism. The length of the wedge 13 in the direction of the longitudinal extension of the temple 3 is selected such that during the entire possible rotational movement of the temple 3, the projection 14 is slidable along the wedge 13.

As can be seen more clearly in Figures 2b, 4b and 7a, the hook-shaped recess 11 is provided with an edging or border 15.
