Description

Personal facial protection device of the visor or similar type

The present invention relates to the field of the protection of persons, in particular in a context of viral and/or bacteriological contamination by projections between subjects in situations of insufficient distance, and relates to a personal facial protection device of the visor or similar type. .

Many solutions for protecting individuals in the context of health measures, particularly in relation to a pandemic episode, are known, including visors. The latter, by their role as screens, prevent contamination of the wearer through the eyes, and to a lesser extent through the nose and mouth, stop the projections generated by the wearer and prevent the latter from touching their face. by reflex.

However, among the common and quasi-systematic symptoms of many viral or bacteriological infections, appearing at a relatively early stage, is an abnormal rise in the body temperature of the infected subject.

It would therefore be beneficial to be able, automatically and easily, to inform a subject under consideration and/or the surrounding persons of an abnormal rise in body temperature, without implementing specific and separate additional means.

The main purpose of the present invention is to meet this demand.

To this end, it relates to a personal facial protection device of the visor or similar type, comprising a protective screen at least partially, advantageously mostly transparent, intended to cover substantially all of the face of the wearer, and a support structure and fastening comprising at least one headband or strap forming a headband or headband, which is elastically deformable and/or adjustable in length, has a part intended to come into application against the forehead of the wearer and comprises sites for fixing the screen, optionally by means of removable links and optionally authorizing a raising/lowering movement by pivoting of the screen, device characterized in that it comprises at least one temperature sensor, arranged and configured to measure the temperature of the head of the wearer of the device.

The invention will be better understood, thanks to the description below, which relates to preferred embodiments, given by way of non-limiting examples, and explained with reference to the appended diagrammatic drawings, in which:

and [Fig. 1B] are perspective views from two different directions of a face protection device of the visor type according to a first embodiment of the invention;

is a perspective view of the front support component, and,

is a perspective view of a pre-assembled sub-assembly formed by combining the components of FIGS. 5B and 5C.

As shown in Figures 1, 2 and 4, the invention relates to a personal device (1) for facial protection of the visor or similar type, comprising a protective screen (2) at least partially, advantageously mostly transparent, intended to substantially cover entirely the face (3) of the wearer (3'), and a support and attachment structure (4) comprising at least one headband or strap (5) forming a headband or headband.

This headband or strap (5) is elastically deformable and/or adjustable in length, has a part (5') intended to come into application against the forehead (3'') of the wearer (3') and comprises sites (6 ) for fixing the screen (2), possibly by means of removable links and possibly allowing a raising/lowering movement by pivoting the screen (2).

According to the invention, this device (1) further comprises at least one temperature sensor (7), arranged and configured to measure the temperature of the head of the wearer (3') of the device (1).

Thus, without implementing a separate additional means, or performing any particular act, the wearer of the visor (1) according to the invention and/or the surrounding people can be permanently informed of the state of a primary physiological parameter, making it possible to carry out an initial diagnosis of said wearer, in particular in the presence of other symptoms typical of a pathological state or of a determined disease, and to take measures, if necessary recommended.

In accordance with an important feature of the invention, said at least one temperature sensor (7) is a contact measurement sensor, advantageously with a flat and flexible structure, preferably in the form of a strip portion or strip. Depending on its nature, its constitution and its mode of assembly with the visor, said sensor (7) can either be attached to, or integrated into, a part of the device (1) coming into application against the wearer's face. (3').

More precisely, it can be advantageously provided that the temperature sensor (7) is attached to, or integrated into, the part (5') of the headband or of the strap (5) coming into application against the forehead (3'') of the carrier (3'), located between the two attachment sites (6) and advantageously having a semi-rigid consistency, which can be bent, but not stretched, elastically

The sensor (7) is therefore permanently in contact with a defined zone of the wearer's head (3') and is a reference for the acquisition of the temperature. The quality of the contact and the wearing comfort of the visor (1) can be controlled by providing a specifically adapted coating on the inside face of the part (5') of the headband strap (5) (mouse, rubber, …).

In order to allow good air circulation, limit the formation of mist and allow, where applicable, pivoting without interference, the protective screen (2), and where applicable its attachment support (2') connected to the sites fixing (6), is configured to extend away from the part (5 ') of the headband or the strap (5) located between the two fixing sites (6) and forming a frontal support, this with constitution of a gap (8) in the shape of a crescent and at a sufficient distance to allow the wearing of a respiratory mask under the screen (2). Such an offset between said part (5') in frontal support and the support (2') - and therefore the screen (2) - also allows the wearing of eyeglasses by the wearer under the visor device (1) .

Where appropriate, and as emerges from the appended figures, in particular from Figure 6, the support (2') in the form of a portion of semi-rigid and bendable strip and the front part (5') of the strap (5 ) can be in the form of a subassembly (10) preassembled (and optionally articulated) at the attachment sites (6). The screen (2) can then for example be secured (possibly interchangeably) by clipping or riveting on the support (2') and the complementary, adjustable and/or deformable part of the strap (5) be secured to the front part (5'), beyond the sites (6).

To prevent the screen (2) from being raised, by pivoting around the attachment sites (6), the visor device (1) may comprise at least one locking means (11) preventing the raising of said screen (2 ), relative to the structure (4) and therefore to the face (3) of the wearer (3'). As shown in the appended figures, a locking means (11) can be associated with each attachment site (6), for example in the form of a rivet or lug which engages in an orifice of the support strip (2' ) of the screen (2). This means 11 can be absent or deleted when a bearing must be possible.

Figures 5 and 6 illustrate by way of example a possible embodiment of the components and their method of assembly for obtaining the subassembly (10) constituting, with the structure (4) of support and attachment, the one of the two component parts of the visor device (1) of Figures 1 and 2.

Figures 5A and 5B show the flank (2'') of sheet of transparent material constituting the screen (2), the strip (2') forming the attachment support and the fastening means (2''') - rivet , before and after assembly of the screen (2). Figure 5C shows the strip forming the front support (5') of the structure (4) with two locking means (11). Figure 6 shows the subassembly (10) formed after assembly of the elements of Figures 5B and 5C at the attachment sites (6) and placement of a layer of foam (12) on the part (5 ') front support, and before fitting the sensor (7).

The sidewall (2'') is preferably made of a transparent, anti-scratch, anti-fog and anti-glare material, or has been treated for these purposes. As far as possible the various components of the devices (1) are made of plastic materials, such as polyethylene, polyester or even polycarbonate. For example, the materials that can be considered for the transparent screen (2'') are PC (Polycarbonate), PETG (glycolized polyester) or transparent PVC (Polyvinyl chloride). The strips (2') and (5') can be made of PE (Polyethylene).

According to an extremely preferred characteristic of the invention, the temperature sensor (7) is a passive element, comprising at least one component of which at least one apparent physical characteristic, in particular visual, is influenced directly or indirectly by the temperature, preferably a plurality of elementary components reacting to different and incremental temperature values, or selectively activated according to the detection of such values.

For example, the temperature sensor (7) can consist of a sensor with variable quantitative and/or qualitative display, for example by variable colored pigmentation, by activation of variable quantities of pixels, or even by selective activation of zones (7') having thermal activation thresholds of different values, such as for example a liquid crystal strip.

A sensor of the type known under the designation Exacto Thermotest (registered name) by the company BioSynex can for example be implemented within the scope of the present invention.

Different constructive variants of the visor (1), in particular in relation to different arrangements of the sensor (7), can be envisaged, depending on the mode of taking into account the measured temperature.

Thus, when the temperature measurement information is intended for the wearer of the visor (1), the assembly is carried out in such a way that the display of the temperature sensor (7) is visible inside the visor. In other words, the wearer will have to remove the device (1) to read the measured value and in this case it will be preferable for the sensor (7) to have a certain latency, or low reactivity to temperature variations, so that the reading is not distorted (a latency of about 10 seconds at least, for example, is desirable).

As a variant, when the measurement information is intended for other people, for example control personnel, or automatic control means, the assembly is carried out in such a way that the display of the temperature sensor (7) is visible from the outside at the level of the part (5') of the headband or of the strap (5) coming to rest against the forehead (3''), through the protective screen (2) and, where applicable, its hanging bracket (2'). In this case, the part (5') and the support (2') consist of a transparent material, like the screen (2).

Finally, it can also be provided that the display of the temperature sensor (7) is visible from the inside and from the outside, said sensor then being able, for example, itself to be made of a transparent material.

In order to be able to guarantee a firm hold of the device (1) on the head of the wearer, it can be provided, as shown in Figures 1, 2 and 4, that the support and attachment structure (4) comprises at least one second strap (9), adjustable in length and/or elastic, intended to extend over the wearer's head (3') and to connect the front and rear parts of the headband (5).

Finally, in order to be able to ensure continuous monitoring and possibly subsequent use of the measurement data collected during the wearing of the device (1) (by the same user), this device may also comprise a means of storing the values measured by the sensor temperature (7) during at least one carrying phase of the device (1), and optionally a means of signaling the exceeding of a limit threshold value.

Of course, the invention is not limited to the embodiments described and shown in the appended drawings. Modifications remain possible, in particular from the point of view of the constitution of the various elements or by substitution of technical equivalents, without thereby departing from the scope of protection of the invention.
