Definitions

• 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.
• glasses 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.
• frame glasses the glasses lenses are fitted into the frame edges provided with a triangular groove.
• 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.
• the glasses are pierced at the attachment points of the bridge and the temple and are held there by a clamp and screw.
• 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.
• 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.
• 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.
• 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.
• 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.
• 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 .
• 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.
• 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.
• 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.
• 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.
• 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.
• 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.
• 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.
• 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.
• the surfaces of the support elements facing the head of the spectacle wearer are provided with an elastic surface.
• an elastic surface can be formed, for example, by a gel cushion.
• 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.

• 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.
• 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.
