FR2564995A1 - Anti-misting anti-icing device for ski goggles - Google Patents

Abstract

The present invention relates to a device preventing ice deposition and misting on the ski-goggle lens. It is characterised in that the transparent plastic lens 1 is open at a determined part 4 in the direction of the length, allowing the air inside the ski goggle to be filtered so as to cause air to circulate naturally, along the upper part of the goggles, from the bottom up, which is the principle of the invention, only when the user is moving and which is facilitated by entry (of air) into the goggles via a wall 5 and by exiting via an orifice 6. The device according to the invention is particularly intended for the motorcycle-ski (skidoo) sport.

Description

 the present invention relates to a device preventing, the spite of fogging and frost on the glass of ski glasses.

 we know that all glasses for skiing or sport have a fog on the glass when it rains and winter mainly when it is; cold this fogging is caused by the heat of the eyes and of the figure under the lens which makes fogging, means acle mine represents an advantage of having a real air circulation at room temperature of the two optics of the lens of glasses only, and without blow fresh air over the user's eyes.

the device according to the invention makes it possible to remedy this drawback, characterized in that the transparent plastic bezel is open in a calculated part and in the width direction allowing the air to filter inside the bezel and so as to circulate the air along the upper part of the bezel, and from bottom to top the bottom of the bezel overlapping slightly under the upper part of the bezel this is what allows air to circulate from the bottom at the top and remove the fogging u on the upper part of the transparent plastic bezel, the temperature remaining the same on both sides of the bezel glass only on the upper part of the bezel, outside and inside
FIG. 1 represents, in section, the device according to the invention.

Figure 2 shows, in section, a variant of this device
the device represented in FIG. 1 comprises the transparent plastic lens (1) and open to a calculated part (4) in the width direction allowing the air to filter inside the lens t and so as to make circulate the air along the upper part, of the telescope from bottom to top naturally, which is the principle of the invention only when the user is in motion and which is facilitated when re-entering the telescope ((l 'air)) by a wall (5) and at the outlet also by an orifice (6).

 the device according to the invention is particularly intended for the motorcycle-cycle industry and can be valid for all sports glasses.

Claims (3)

 1) device preventing the deposition of frost and mist on the transparent plastic bezel for skiing, characterized in that the transparent plastic bezel (1) is open to a calculated part (4) in the direction of the width.  2) device according to claim (1) and allowing the air to filter inside the ski goggle, and so as to circulate the air along the upper part of the moon head from bottom to top, naturally, which is the principle of the invention, only, when the user is in motion and which is facilitated upon reentry into the telescope ((the air)) by a wall (5) and at the outlet by an orifice ( 6).  3) device according to claims (1) and (2) has an orifice (2) provided for laying the elastic fixing the bezel on the head of the user, and a protective bead (3) between the telescope and the figure of the user, the plastic may cause injury.
