Description

Technical field

The invention relates to sports goggles for swimming.

State of the art

The closest to the present invention are intra-orbital goggles for swimming (US patent No. 5,331,691, publ. In 1994), containing two small, transparent glasses, with several zones of the form of glasses, including the Central area of the flat lens of the glasses and the area of the circumferential walls of the eyeglass from the lens to the orbit of the eye socket, the central mounts for the tie-bridge over the bridge of the nose and the lateral mounts for elastic ties around the head.

The limited usability of these glasses, especially in competitions, is due to the use of a combination of zones of the shape of the glasses that are not effective enough for side view without smooth transitions between them, as well as the presence of opaque gaskets-seals at the edges of the circumferential walls, the shape of the zones of fasteners and screeds, which together are also significantly reduce lateral view of the swimmer.

Disclosure of invention

The objective of the invention is to significantly improve the usability of the glasses, namely: providing a significantly better view of the swimmer, especially his side view, and ensuring reliable sealing of the eyes under the glasses while significantly reducing the pressure of the glasses on the eyes, orbits, head and in the absence of gaskets-seals while the function of the shutter is performed by the soft tissue of the skin inside the orbits of the orbits. Also, the decrease in the hydroresistance of the glasses due to their extremely small size and the additional ease of use of glasses for deep eye sockets and a high bridge of the swimmer.

The technical result is achieved by the fact that the small intra-orbital goggles for swimming contain two small transparent glasses, with several zones of the shape of the glasses, including the central zone of the flat lens of the glasses and the zone of the surrounding walls of the glasses from the lens to the orbit of the orbit, central mounts for the bridge over the bridge of the nose and side mounts for elastic ties around the head. Points are distinguished by the fact that both points have an additional zone of shape of the bevels of the side view and radii of rounding of transitions of all zones of the form of glasses. The circumferential walls have small sealing bends (flanging) of the edges to the outside. The glasses have high thin holders for fastening to the bridge of the nose for thin inelastic but flexible in the places of fastening of the tie-bridge and have small holders as fastenings for the temples also with a thin inelastic but flexible tie to the temple area to go to the soft-elastic screed around heads.

At the same time, to simplify the manufacture, both points are the same (there is no left and right points), with the symmetry of the upper and lower halves, and are alternately extruded in a single matrix with a single punch, the main material of the glasses is plexiglass, which is more plastic, better extruded, more pleasant in tactile contact with soft skin tissues inside the orbits of the orbits (compared with traditional polycarbonate).

A soft-elastic screed can be round rubber twine (mainly its double loop). A thin inelastic (practically non-stretching), but flexible screed can be a non-soaking thread in water, for example, a kapron thread (also mainly a double loop). Above the bridge of the nose, this thread can be further hidden inside a thin protective tube-nipple to soften contact with the bridge of the nose.

List of figures:

Figure 2 is a top view of the glasses;

Figure 4 is a front view of the glasses.

The implementation of the invention

On the views, the positions marked zones and elements of points: 1 - the central zone of the lens of the point; 2 - zone of lateral bevel; 3 - zone of the circumferential wall of the point; 4 - a small limb of the edge of the circumferential wall outward; 5 - attachment to the bridge of the nose for the jumper; 6 - jumper (thread in the tube-nipple) over the nose; 7 - fastening to the temple, 8 - transitional thread; 9 - tightening round rubber twine.

Improving visibility is provided by two zones of each point (central for direct viewing and side view with a rounded transition between them), the fundamental absence of an opaque wide shutter and the maximum displacement of the mount holders on the sides of the eyes. Flat parts of the lenses of both zones do not distort the image, and rounding off the transitions of the zones do not break the field of view into parts, so you don’t have to turn your head at all during the swim.

Zones of sufficiently large lateral bevels are designed to expand the field of view, especially when swimming on the back. Values of parameters: obtuse angle between the planes of the central zone and the side bevel zone in the place of the rounded transition between the zones - 115 ... 125 degrees, rounding radii - 1.5 ... 2 mm, the edge bend outward - 1.5 ... 2 mm, the wall thickness of the glasses - 1.6 ... 1.9 mm. Perhaps anti-fog coating (against fogging glasses) and darkening against bright light.

Reliable sealing is ensured by high holders at the bridge of the nose (they do not hang on the nose with a gap at the bridge of the nose, and the inelastic, but flexible at the attachment points over the bridge of the nose ensures an independent fit of each point precisely in place), small bends of the peripheral walls in contact with soft tissues skin inside the orbits of the orbits. Pressure reduction is ensured by soft and fairly weak rubber twine, due to the natural suction effect of soft skin tissues inside the orbits of the orbits.

Small intra (inside) orbital lenses provide sufficient tightness even with round rubber cord loosely stretched around the head, practically without creating pressure on the eye sockets and through them on the eyes. Rubber twine is softer than traditional rubber bands. An additional layer (seal) is not required for sealing; the sealing function is performed by a small bending (flanging) of the edge of the eyeglass wall to the outside and soft skin tissues in contact with the limb inside the orbits of the orbits.

Small holders for temples for rubber twine around the head through a transitional nylon thread do not interfere with the side view and it is convenient to correct or remove glasses for them. The intermediate thread is threaded into the “ears” of the fastener and it is easier to fasten them than a rubber twine, which in addition also breaks down (breaks) more often. It is easier to thread it into the loop of the thread and tie it in a knot.

Thin high holders for the bridge over the bridge of the nose also practically do not interfere with the review and are especially good for the high bridge of the nose and / or deep-set eyes to ensure reliable contact between the glasses and the orbits. The jumper of the glasses is made of a non-stretchable, but flexible thread, so that its position is not affected by the tension of the rubber cord around the head, for each point you can adjust its optimal fit in your eye socket, taking into account the small natural asymmetry of the halves of the face and, accordingly, the asymmetry of the position of the eye sockets and eye relative to nose and nose. At the same time, the glasses are very compact in size and practically do not create resistance when swimming.

When swimming with great visibility of the proposed glasses, there is no need to constantly turn your head while competing with rivals. When swimming especially on the back, the central zone of the lenses of the glasses is practically not used (only when looking at the ceiling), and the zones of the side bevels of the glasses offered make it possible to see what is happening on the side above and under the water, just by squinting your eyes to the side without turning your head and also slightly bowing head to the side, see under water forward in the direction of travel (for example, a side, an opponent in front of you). The zone of the circumferential wall allows you to see from behind without raising your head and in front, slightly raising your head.

The proposed glasses are used as follows.

It is better to wear these glasses in a different way than they usually do, namely: they usually put glasses in the eye sockets first, and then pull on and fix the rubber screed around the head. And with the proposed glasses, it is better to first pull a soft-elastic rubber twine on the head, and then from the forehead to push the glasses over the eyes for the side holders. The glasses are positioned in the orbits of the eye sockets and, slightly moving, press down - while the air partially leaves the air from the bends of the edges of the glasses, and the glasses themselves are attached to the soft tissues of the skin inside the orbits of the eye sockets due to the small difference in air pressure outside and inside the glasses.

And, finally, as a rule, swimmers remove glasses from their eyes when they are not needed to give the eyes a rest from the sufficiently strong pressure of the edges of the glasses with shutters. In the proposed glasses, this is not necessary. They can swim and relax in between throughout the workout. The eyes practically do not get tired, because the pressure on the eyes and the eye sockets of the edges is small, the rubber cord is stretched loosely around the head, and the sealing of the eyes from the water is still guaranteed to be good.
