Abstract

The invention relates to spectacles comprising two spectacle lenses (1, 2), at least one resting surface (6) for the nose of a spectacles wearer, and two supporting elements (7, 8) which are laterally arrange on the spectacle lenses (1, 2). The length of the supporting elements is measured such that they do not project beyond the temples of the spectacles wearer. The supporting elements (7, 8) comprise resting elements (16, 17) on the sides facing the head of the spectacles wearer, especially on the end areas (18) thereof which face the temples of the spectacles wearer. The inventive spectacles also comprise a hinge (11) which is arranged between the spectacle lenses (1, 2), whereby the spectacles can be placed in a non-use position in which they can be folded so that the spectacle lenses (1, 2) are arranged one above the other, and they can be unfolded into a position for wearing. The inventive spectacles are characterized in that the supporting elements (7, 8) form a fixed angle with the respective adjacent lens (1, 2) which preferably ranges from 60° to 120°, and a spring element (15) is arranged in the area of the hinge (11). The spring element (15) presses the supporting elements (7, 8) against the temple areas of the spectacles wearer in the vicinity of the resting elements (16, 17) so that the supporting elements (7, 8) are held on the head of the spectacles wearer in a positive fit manner.

Description

Description: glasses frame

The invention relates to glasses with at least one spectacle lens, at least one support surface for the nose of a spectacle wearer and two laterally arranged, pivotable support elements.

Different types of glasses are known. They consist of a support frame made of metal and / or plastic, which is usually provided with ear hooks, and two spectacle lenses connected to one another by a frame or by fittings. In the case of frame glasses, the glasses lenses are fitted into the frame edges provided with a triangular groove. In the case of saddle-frame glasses, these are in turn connected by a saddle or, in the case of side-bridge glasses, by a bridge that does not lie on, with movable side rails resting on the side of the nose. Saddle bridge glasses are also known in which the spectacle lenses are formed in one piece and the saddle is formed by a bulge of the spectacle lens in the area of the nose. The brackets resting on the ears are pivotally attached to the frame edges by joints.

In rimless glasses, the glasses are pierced at the attachment points of the bridge and the temple and are held there by a clamp and screw.

There have been some efforts to increase the wearing comfort of glasses by a special design of the glasses frame. For example, EP 0 825 475 A1 discloses glasses with pivotably mounted earpieces with a spring mechanism, which allows the earpieces to be pivoted apart from the normal, open position when used against the spring force. This makes it possible for a person wearing glasses to pull the glasses away from the head with a lateral movement instead of always in the direction of the Need to remove the visual field from the head.

All these glasses have in common that the temple behind the ears can be annoying at times, in particular to pressure points or skin irritation.

Non-iron side bridge glasses with a spring-compressing bridge are known as pinchers. These glasses are only fixed on the nose. The spring forces acting on the nose are high, so that pressure points can arise here, from which the wearing comfort suffers considerably. The invention is therefore based on the object of designing glasses which do not have the aforementioned disadvantages.

This object is achieved in that the glasses according to the invention have two glasses, at least one support surface for the nose of a glasses wearer, two support elements arranged on the side of the glasses, a joint arranged between the glasses and a spring-elastic element arranged in the area of this joint. Because of the joint, the glasses have a wearing position and a rest position with glasses lying essentially on top of each other.

The carrier elements enclose a fixed angle with the adjacent glass, the angle preferably being between 60 ° and 120 °. The length of the support elements is dimensioned such that their support elements, when worn by an eyeglass wearer, do not protrude beyond the temples of the eyeglass wearer. The support elements have support elements on their sides facing the head of the spectacle wearer. The spring-elastic element arranged between the spectacle lenses presses the carrier elements in the area of the support elements against the temples of the spectacle wearer, so that the carrier elements hold non-positively on the head of the spectacle wearer. Overall, there is a particularly secure hold of the glasses due to the frictional connection between the support elements and the temples of the glasses wearer and the support surface with the nose of the glasses wearer.

The support of the glasses according to the invention, which results from the force exerted by the spring-elastic element on the temples of the glasses wearer, is supported if the laterally arranged support elements are designed to be as rigid as possible, in particular having the least possible flexibility. This can be achieved, for example, by means of metallic carrier elements with a suitable cross section. A comparable effect can also be achieved using a suitable plastic, in particular a fiber-reinforced plastic.

A particularly advantageous effect results when the joint and the spring-elastic element are combined in one component, this one component having both a joint effect and a spring effect. Such an element can be realized, for example, by a web that connects the spectacle lenses to one another, in particular, for example, by a nose piece, which consists of an elastically deformable metal.

The resilient element can also consist of an elastically deformable plastic. In particular, it is possible to realize a component from such a plastic, which exhibits both a joint effect and a spring effect.

A particularly advantageous effect results if such a plastic is selected for the resilient element which can be elastically deformed and has a high internal damping, so that the resilient Element can be deformed relatively quickly under the influence of external forces, and the resilient element moves relatively slowly back into its starting position without the influence of external forces. It is particularly advantageous if the resetting movement of the resilient element takes at least five seconds, preferably 15 seconds.

The support elements can be formed by rubber-elastic, essentially spherical elements, which are arranged in particular at the ends of the carrier elements. When using such support elements, a particularly tight fit of the glasses can be achieved if the length of the support elements is selected such that the spherical support elements are positioned approximately in the area of the temple-side ends of the eyebrow arches of the glasses wearer when the glasses sit on the nose of a glasses wearer .

Even without spherical support elements, a particularly secure fit of the support elements on the temple-side ends of the eyebrow arches of the spectacle wearer can be achieved by a suitable choice of the length of the support elements and the position of the support elements fastened on their inner sides. This can be achieved in particular if the length of the carrier elements is between 1.5 cm and 4.5 cm.

In a further advantageous embodiment, the axis of rotation of the joint, which is arranged between the glasses, forms an angle of less than 90 °, preferably less than 80 °, in particular less than 70 °, with the straight line which runs through the two highest points of the glasses . It is particularly advantageous here if the axis of rotation of the joint runs essentially in the plane defined by the spectacle lenses or a plane parallel to it. Such an orientation of the axis of rotation of the joint leads to the fact that the support elements of the glasses do not lie directly one above the other in the rest position, which is characterized by glasses placed one on top of the other, but side by side. By a suitable choice of the angle of the axis of rotation with the straight line mentioned, it can be achieved that the support elements come to lie completely next to one another in the rest position.

It is also advantageous if the glasses are locked in the rest position mentioned. This can be achieved, for example, by a non-positive or positive locking of the support elements and / or the support elements. A version of the glasses with a non-perpendicular arrangement of the axis of rotation of the joint to the straight line that runs through the two highest points of the glasses is particularly favorable for this.

A further advantageous development results if the glasses have at least one spring-elastic element which presses the carrier elements onto the head of the spectacle wearer, so that the carrier elements hold non-positively on the head of the spectacle wearer. With such glasses, an ear hook is not necessary. It is sufficient if the carrier elements cover part of the temples of the spectacle wearer. In this area, the carrier elements are fixed by the contact pressure of the resilient element, so that the glasses resting on the nose are adequately secured against slipping. Since the surface of the carrier element resting on the head is large in comparison to the contact surface of the pince-nez, pressure points can essentially be avoided. In a preferred embodiment, the glasses have two glasses, which are connected to one another via the spring-elastic element. The spring-elastic element can consist, for example, of a spring-elastic plastic bracket, in which the spectacle lenses are in a rest position. gene, wherein the glasses can be opened against a spring force. A spiral spring can also be used as a spring-elastic element, the ends of which are connected to a pair of spectacle lenses, if necessary, via articulated bridges.

The carrier elements can be arranged on the glasses in such a way that they can be pivoted from a position substantially parallel to the glasses to a position in which the glasses can be put on by the glasses wearer. When folded, these glasses are particularly small, since the glasses lie on top of each other and the folded support elements only protrude little, if at all, over the edge of the glasses.

The carrier elements can also be firmly connected to the glasses, in which case they can then be pivoted together with the glasses.

In a special embodiment of this embodiment, the spectacle lenses are connected to one another via two webs, the spring-elastic element being arranged between the webs and each web being provided with a lever arm in the region of the spring-elastic element, the lever arms enclosing an angle in a folded state of the glasses and lie against each other when the glasses are open. The lever arms can be used to open the glasses by pushing them towards each other against the spring force.

The resilient element can be designed as a spiral spring, the ends of which are connected to the lever arms.

In another advantageous embodiment of the invention, the carrier elements connected to the lens via spring-elastic elements. This has the advantage that the nose piece can be designed freely without having to consider a spring-elastic element.

It is advantageous if the surfaces of the support elements facing the head of the spectacle wearer are provided with an elastic surface. As a result, the shape of the support element can adapt to the shape of the head, so that the contact area between the support element and the head is as large as possible and the frictional forces are as high as possible. Such an elastic surface can be formed, for example, by a gel cushion.

To increase the frictional forces, it is also advantageous if the surfaces of the support elements facing the head of the spectacle wearer have a surface with a high coefficient of friction. So the surface can preferably consist of a neoprene-like material.

The invention is explained in more detail below with the aid of a preferred exemplary embodiment.

Show it:

The illustrated embodiment of the glasses according to the invention, as can be seen in particular in FIG. 1, has a first and a second spectacle lens 1, 2, which are framed in frames 3, 4, the frames via a nose clip 5 with a support surface 6 for the Nose of a spectacle wearer are interconnected. Carrier elements 7, 8 are firmly connected to the outer sides of the frames.

The nose clip 5 has two webs 9, 10 forming a saddle, which - as shown in FIG. 2 - are pivotally connected to one another via a joint 11 with an axis 12. In the area of the joint 11, the webs are provided with lever arms 13, 14 running perpendicular to their longitudinal axis.

A spiral spring 15 is arranged around the axis 12 of the joint 11 (see FIG. 3), the free ends of which engage in a lever arm 13, 14 (not shown). As a result, the lever arms 13, 14 lying against one another in an opened state of the spectacles are pressed apart, so that the spectacle lenses 3, 4 and thus the carrier elements 7, 8 are pivoted toward one another about the joint axis 12. If the glasses are worn, the support elements 7, 8 are thus pressed onto the head of the glasses wearer and fixed. In particular, the rubber-elastic spherical support elements 16, 17 are pressed. FIG. 4 shows a nose piece 5 of a further exemplary embodiment in an enlarged view. The glasses are in the wearing position. A recess is provided in the first web 9, into which a second web 10 engages with a pin. This pin is rotatably mounted in the recess of the first web 9 by means of an axis 12. In this way, the joint 1 1 is formed. The angle of rotation of the joint 11 is limited by a surface forming a stop on the back of the recess in the first web 9, against which the pin of the second web 10 strikes. This is also clear from Figure 5, which shows the nose piece of this embodiment in the rest position of the glasses. The second web 10 is pivoted about the axis 12 of the joint 11 against the first web 9. The surface forming a stop becomes visible on this. This is covered with a spring-elastic element 15, which is elastically deformed when the glasses are in the wearing position. Due to the restoring effect of the resilient element 15, the latter exerts a contact pressure of the carrier elements and in particular of the support elements 16, 17 against the temples of the spectacle wearer. If the glasses are removed, they are returned to the rest position under the influence of the restoring action of the spring-elastic element.

Such a resilient element can be produced, for example, from a foam-like plastic from 3M, as is known for the production of earplugs for insertion into the human auditory canal. Such a plastic has a high elasticity and can be highly compressed. If no external forces are applied, the plastic relaxes into its initial position, this relaxation taking place slowly, in particular over a period of more than five, preferably more than 15 seconds, due to the strong internal damping of the plastic. A third exemplary embodiment is shown in FIG. 6. This essentially includes Chen another embodiment of the joint 1 1 and the spring-elastic element 15. Both elements are combined in one component 19. In this embodiment, the component consists of a plastic or metal section, which is attached between the partial webs 9 and 10 in the nose clip 5. This component combines the joint action of the joint 11 with the spring action of the spring-elastic element 15. It has, for example, a rest position, as can be seen from FIG. 7 in supervision. If glasses according to this exemplary embodiment are put on by a spectacle wearer, the distance between the contact surfaces 18 increases, as a result of which the component 19 is elastically deformed. In this way, a restoring force is set which securely non-positively fixes the contact surfaces 18 and thus the carrier elements 7 and 8 to the temples of the spectacle wearer.

In a further advantageous embodiment, the element 19 can be made much more angled, so that in the starting position of the construction part 19, the rest position of the glasses, characterized by glasses 1, 2 which are essentially superimposed, is taken. Comparable can of course also be achieved with other spring-elastic elements 15 and joints 11. The rest position of glasses with joint 11 and separate spring-elastic element 15 can be seen in FIG. 9.

In an advantageous development, the glasses are fixed in the rest position, in particular by means of positive or non-positive hooking of the carrier elements 7, 8 and / or the support elements 16, 17. This can be achieved in particular by the fact that the axis of rotation of the joint 15 makes an angle of forms less than 90 °, preferably less than 80 °, in particular less than 70 ° with the straight line which runs through the two highest points 20 of glasses 1 and 2. This is shown in Figure 8. With such an execution of the Steering 15, the rest position of the glasses is characterized in that the glasses 1, 2 are not completely covered. In particular, the carrier elements 7, 8 are not congruent. By a suitable choice of the angle α, it can be achieved that the carrier elements 7, 8 come to lie side by side. In this way, it can be achieved without further measures that the carrier elements 7, 8 and / or the support elements 16, 17 hook in a non-positive or positive manner, and thus fix the glasses in the rest position. Furthermore, additional shapes can be provided on the carrier elements 7, 8 and / or the support elements 16, 17, which preferably hook in a form-fitting manner in the rest position of the glasses.

An increased wearing comfort with a particularly secure fit results if the support elements 16, 17 rest against the ends of the eyebrow arches on the temple side when the glasses are worn by a spectacle wearer. In this area, the anatomy of the human skull has depressions in which, in particular, spherical support elements 16, 17 hold particularly securely. Due to the additional form fit that results here, the pressure force exerted by the spring-elastic element 15 can be kept particularly low, which results in increased wearing comfort.

Further advantages result from spectacles with at least one spectacle lens 1, 2, at least one support surface 6 for the nose of a spectacle wearer and two laterally arranged, pivotable support elements 7, 8, the spectacles having at least one spring-elastic element that supports the support elements 7, 8 presses against the head of the spectacle wearer, so that the support elements 7, 8 hold firmly on the head of the spectacle wearer. In particular, two spectacle lenses 1, 2 can be connected to one another via the spring-elastic element. Further advantages result if the spectacle lenses 1, 2 are connected to one another via two webs 9, 10, the spring-elastic element being arranged between the webs 9, 10 and each web 9, 10 in the region of the spring-elastic element having a lever arm 13, 14 is provided, the lever arms 13, 14 enclosing an angle in a folded state of the glasses and abutting one another in an opened state of the glasses. In this embodiment, the resilient element is advantageously realized by means of a spiral spring 15, the ends of which are connected to the lever arms 13, 14.

An advantageous effect can also be achieved in that the carrier elements 7, 8 are connected to the spectacle lens (s) 1, 2 via spring-elastic elements.

In all exemplary embodiments, it is advantageous if the surfaces of the support elements (7, 8) facing the head of the spectacle wearer are provided with an elastic surface. In particular, the elastic surface can be formed by a gel cushion. Overall, it is advantageous if the surfaces of the carrier elements (7, 8) facing the head of the spectacle wearer have a surface with a high coefficient of friction. This can be achieved, for example, by a surface made of a neoprene-like material.
