"Glasses, especially for skiing".

The present hiring concerns so-called ski goggles and in particular those glasses which are equipped with means that can help prevent fogging.

In the following description the term "ski goggles" will be used, but it will be understood that such goggles also may have other uses than those in the only one preferred example.

The ski goggles generally have a frame on which A colored pane made of plastic glass (acrylic glass) is attached in a possibly exchangeable V / eise. The essential one The disadvantage of the known glasses is due to the fact that the breath has the tendency to settle down on the disc hit, preventing a clear view.

As a result, air openings are provided on certain ski goggles, which allow this deficiency of the accomodation to: -f: -_ ^: to help, but which, however, are of a certain speed- - ^: - - ^ - ^; e -ij / 'm- ¹ · cause an air flow that is like this

violent is that it is uncomfortable and even painful for the person Eyes of the user. This has led to the provision of locking flaps with manual operation in front of these openings, which can be brought into a position in which they release the openings as well as in a closed position. Few of these devices are practical because, in general, the user wears thick gloves and it is not easy to operate the closing flaps. Otherwise are these flaps are complicated and sensitive to the price these glasses.

The aim of the innovation is to eliminate these various disadvantages. Its subject is improved glasses, which is particularly useful for skiing, it consists of a frame on which a disc of transparent Material is attached and at least one air passage which is provided with a closure flap, which Glasses are particularly characterized in that the closure flap so arranged on the stand that they are around a Axis of rotation can swing freely, the arrangement being such that when the speed of the user in relation to the surrounding loft is below a predetermined value, the flap is usually in an opening point of the air through is under the action of their own weight while

if the relative speed has this predetermined value reached, the flap in a closed position of the passage is held under the influence of the force resulting from this relative speed.

The main advantage that the innovation brings is the automatic passage of the or each closure flap in the appropriate position depending on the conditions of use is.

Other features and advantages of the innovation appear in the course of the following description, which refers to the attached drawing refers, which is given as an exemplary embodiment, and in which:

Fig. 1 is a perspective view of the glasses according to the invention;

Fig. 2 is a section on the line H-II of Fig. 1;

FIGS. 3 and 4 are side views showing the flaps, "each in the open position and in the closed position.

The drawing shows an exemplary embodiment of ski goggles shown to which the improvement according to the innovation is appropriate.

These glasses have a frame 1, which consists of a plastic Material is cast on which a colored disc 2 made of an acrylic glass or a corresponding material is attached is. This disk can be fixed in a known manner or it can be fastened in an exchangeable manner. The frame 1 has also an elastic fastening band 3 and a foam strip 4, the with 'ler forehead, the temples, the Nose and the cheekbones of the user comes into contact.

Li the front part la of the frame 1 passages 5 are arranged, while lateral openings 6 are provided between the lateral inner part Iu of this frame and the pane 2 are.

Behind the passages 5 there are branching pia ttbi! 7 (Fig. 2), which are cast together with the frame, and which are intended to direct the air against the inner wall of the pane and 7, v. at the same time to protect the eyes of the user.

A support 8 is fastened with rivets 9 in the celebration passage 5 which serves to support a flap jq. The edition owns two aligned recesses 8a, in which there are two bolts loa, which are made with the flap from the same material

are able to rotate freely. The flap has the shape of an L in cross-section and the bolts loa are near the free one Arranged at the end of one of the arms of the L, so that the flap Io moves under the action of its own weight into an open position ", as indicated by full lines in FIGS. 2 and in the Tig. 3 is shown.

The arm of the L, which is directed forward, preferably has a convex shape.

The lower position of the flap is when the user stands still or moves slowly ". The course is then as shown by the arrows f-,, fp in FIG effective ventilation is achieved.

As the user moves faster, the speed increases in relation to the air and the air that impinges on the disc 2, (f,) in Fig. 4) exerts on the flaps Ic sufficient force to lift them up and rotate them about their axes of rotation and bring them into a locked position to bring, as shown with the broken lines in FIG. 3 and in FIG.

This closure is of course not perfect, so that an air flow is established that is sufficient to prevent the fogging.

It i-, t clear that these flaps have shapes other than those shown are, can give; the essential feature of the innovation is that the passage from one position to the other the flaps takes place automatically under the influence of the conditions of use, without the user having to do anything must do.
