Description

Mask

TECHNICAL SECTOR

The present application refers to a mask, formed by one or more bodies that allow to form a protective mask, attaching a transparent plastic sheet to a visor. In this way, protection of the eyes, face and other wet areas is easily carried out.

It is applicable in the field of protection from occupational and health risks.

STATE OF THE ART

In the protection of workers from occupational and health risks, the use of masks, protective glasses and other similar material is frequent. One of the most complete solutions are the masks with a transparent plate that protects the mouth, nose and eyes from splashes.

If the contamination from which the user is protected is biological or similar, the cleaning of the plates may be insufficient, so it is better to dispose of them.

On the other hand, in emergency situations, it may be necessary to configure a large number of masks easily, cheaply and without the need for special parts to be manufactured in industrial plants and brought to the place of use.

The applicant is not aware of any device similar to the invention or that allows solving these problems.

BRIEF EXPLANATION OF THE INVENTION

The invention consists of a mask according to the first claim. Its different variants solve the problems outlined.

This mask is of the type that includes a transparent plate, protecting the user's face, generally made of plastic. Furthermore, it includes a visor cap and at least one support for fixing the transparent plate to the visor. This fixing support consists of a body with at least two grooves, distributed in two approximately perpendicular groups (for example, between 85 and 110 °). The grooves are configured for insertion and retention of the transparent plate and the visor. A first slot fixes and retains the visor, and a second slot fixes the transparent plate. The body may have several second grooves to hold plates with different chemical or optical properties, or at different angles. Variation of angles can also be achieved by arranging several first grooves with different angles and / or thickness.

This support is very simple, and can be manufactured cheaply and quickly by 3D printers.

Preferably, the grooves are open laterally. That is, they have no side edges. Thus the body can be smaller than the part of the visor and the transparent plate that is inserted into it. For example, the body may be made up of two coupled "U" section prisms.

It is convenient to provide retention elements, such as at least one retention screw (with or without head), teeth or roughness, or an elastic part that presses or pinches the flat element.

It is possible to make the body elastic or flexible so that it follows the curvature defined by the visor. In addition, the elasticity allows you to resume the position if it is temporarily deformed.

To create a clear plate rim above the visor, it is preferable that the first visor attachment slot intersect the According to the groove in a fist, he heard me. s ecr, at the beginning of the first groove intersect with the second groove and not the other way around, and in addition this intersection does not take place in an edge or, at least, not in the closed end of the groove.

Other variants are seen in the rest of the memory.

MODES OF CARRYING OUT THE INVENTION

In the following, an embodiment of the invention is briefly described, as an illustrative and non-limiting example thereof.

The embodiment shown in the figures starts from a body (1) with two or more grooves (2,3). The grooves (2,3) allow the insertion of flat elements (4,5) and preferably do not have lateral edges so as not to limit the dimensions of the flat elements (4,5). For example, the body (1) can be made of two or more coupled "U" section prisms.

In the first grooves (2) the visor (4) of a cap is inserted. One or more transparent plates (5) are inserted in the second grooves (3), generally made of plastic and with different chemical or optical properties. The fastening of the visor (4) and the transparent plate (5) can be done for parts or for these grooves, or for elements or other clamping elements. The mouths of the grooves (2,3) may have teeth (7) or roughness that increases grip. Figures 1 and 2 show the preferred position of the screws (6), aligned with an opposite groove wall (2,3) to increase the retention efficiency.

The grooves (2,3) are grouped into two groups that form an angle (a) that will normally be between 85 and 110 °, but mainly depends on an external element, the shape of the visor (4) for which it is designed, reason why this interval is only indicative. The grooves (2,3) in each group may not be parallel but have a small angle (generally less than 15 °) between them. The grooves (2,3) of each group can be oriented in opposite directions so that the body (1) is more compact (figure 4). In this case, the orientation of the body (1) will be chosen according to the second slot (3) to be used.

Preferably, the first grooves (2) will be at a midpoint of the second grooves (3). In this way, the upper edge of the transparent plate (5) will be above the visor (4) and the entry of material will be prevented or hindered by the slit (8) that remains between the visor (4) and the transparent plate (5). This slit (8) offers an advantage by facilitating perspiration and preventing the transparent plate from tarnishing.

The dimension of the body (1) in the longitudinal direction will generally be one or two centimeters. However, it is advantageous to make it longer and of somewhat flexible material to be able to follow the edge of the visor. In this way, the slit (8) is sealed. This solution is very advantageous in places where contamination can come from a higher point than the user.

Figure 3 shows the final result, in which several bodies (1) are coupled to a visor (4) to hold the transparent plate (5), forming the protective mask. The figure only shows two supports, but it is possible to place several, or one of great length and flexibility.
