Description

Safety goggles, in particular industrial safety goggles

Technical Field

The present invention relates to safety goggles, in particular industrial safety goggles, comprising a piece of lens having associated therewith a transverse transparent part which is integral with the lens and extends towards the head of the user. Safety goggles of the same type are described in DE-U-8902696.

Background

In conventional safety goggles of the same type, the joined side parts are planar, extending from a substantially straight, vertical break line towards the rear. The broken line is located at a position in the lateral viewing angle range, which obstructs the lateral view to a considerable extent.

In known eyewear, the overall curvature of the lens is so great that the lateral ends of the lens surround the user's cheeks all the way to his temples. This type of lens avoids the break line obstructing the view. However, it must have a radius of curvature which forms a large distance from the user's face, which is not preferable in optical principle.

Disclosure of Invention

The object of the present invention is to provide safety goggles of the type described above which have the best ability to protect the eyes from the side and which have the function of not obstructing the side view.

According to the invention, the object is achieved in that the outer end of the side of the lens is curved and the side parts have a curvature which matches the curved contour of the lens.

According to the invention, unlike conventional technical solutions, in which rather complex injection-molded shapes are used, in order to avoid separation lines at the lateral end portions of the lens. While ensuring that the lens attached to the side due to the bending of the lens has a considerable static stability and diverts impact particles from the side. In addition, the rear edge portion of the lens can be made to produce a good fit with its cheek contours at the user's temple.

Preferably, the side member to which the lens is attached has a radius of curvature of 1-3 cm, preferably about 2 cm. With regard to the radius of curvature described above, it is not intended that the entire side piece has the same radius of curvature, but rather that the side piece may have a non-circular curved shape, the radius of curvature substantially reflecting only the bending behaviour.

In another embodiment of the present invention, a stent is provided. The upper side of the lens may be locked in the holder and the arcuate connector may be hinged to the lateral end of the holder. In this case, a clamping element is preferably provided, which clamps the lateral ends of the carrier element and provides the hinge part of the hinge bow.

The hinge on one side of the bracket is provided with a connecting section which is in clamping engagement with the bracket connecting part.

The particular modular structure of the individual elements can therefore be selected according to the particular needs, in particular to provide different bows, and to improve the resistance to impacts.

Preferably, the arcuate connector is made of a softer plastic material than the retaining part of the goggle so as to be easy to wear by the user. At the same time, the flexibility also contributes to an increase in the elasticity, so that the length adjustment is facilitated. The arcuate link has an elongated slot with an engaging recessed portion which engages a locking projection on the inside of the link.

The end of the bracket is engaged with the clip in a forked manner, and a locking protrusion and a locking groove are provided at the front of the clip and the bottom of the forked portion of the side end of the clip, so that the tilt adjustment is performed.

The fork-shaped part at the side end is provided with an upper cover which acts as a stop.

According to an advantage of the invention, the rotational support of the bow may comprise a form in which a rotational support recess is provided in one of the fork portions and a support pin is provided on one side of each of the chucking members, the support pin being engaged with the rotational support recess. The support pins may be made inclined to facilitate the clamping operation.

Preferably, the upper bracket member has an enclosure portion which extends rearwardly toward the face of the user, thus ensuring a positional fit in a forward position, preventing the lens from falling off, and preventing particulate matter from entering the face of the user from above.

On the underside of the stand, the upper stand element is provided with a groove for insertion of the upper edge of the lens. The side ends of the lens are provided with recesses and the upper carrier element is provided with corresponding lateral projections for fixing the lens.

Preferably, the projection of the upper bracket member is downwardly disposed in such a manner that, when the lens is inserted, the inner locating wall of the groove receives the upper edge of the lens, forming a locking engagement in this portion. This is a slide lock fit to secure the lens.

A wire may be incorporated by injection molding in the vicinity of the nose support of the lens. On either side of the nose there are side ends of the nose support that extend outwardly, with the nose support sheet or nose support ring ending at the side end of the nose support. Such constructions are well known from sunglasses or optical glasses but have not been applied to the overall lens of industrial safety eyewear to date. This facilitates particularly convenient wearing of the glasses.

Preferably, the lens is spherically curved, providing good optical performance.

A hole for fastening a safety belt may be provided at the end of the bow.

Another nasal support may be provided that is disposed on the carrier by injection molding.

It is also possible to provide another lens having a plate member connected thereto, the plate member extending rearward, the plate member being provided with a long hole inclined to the horizontal direction, and the holder being provided with a corresponding columnar locking projection which can be inserted into the long hole and fixed by rotating the holder, the lens having a central locking projection, and the holder having an engaging recess.
