Description

Face protection device

Cross Reference to Related Applications

The present patent application claims priority from german patent application DE 102016205448.1, the entire contents of which are incorporated herein by reference.

Technical Field

The invention relates to a face shield, in particular for a safety helmet. Furthermore, the invention is based on an additional grille element for such a facing device. The invention also relates to a safety helmet comprising such a face-protecting device.

Background

It is previously known from common prior use to provide so-called forest worker equipment for the work of forest workers in forests. Forestry worker equipment typically includes a work safety helmet and ear protectors mounted on the work safety helmet and a grid visor attached to the work safety helmet to protect the forestry worker from encountering fly-wood chips that are often generated when sawing trunks, branches, etc. In this case, it is disadvantageous that the grid protector cannot sufficiently prevent branches of the grid protector from being hit at high speed. Most industrial accidents of forestry workers can be attributed to this.

Helmet visors of shock-resistant plastic material are also known from the prior art, which are well protected against mechanical influences, for example tree branches. However, a disadvantage of such a helmet visor is that the wood chips, due to their resin, stick together during forestry work, which can impair the vision of forestry workers, resulting in a new source of danger.

DE 29708134U 1 discloses a forestry worker safety helmet comprising a visor which can be pivoted in front of the field of view. The helmet also has a helmet screen that protrudes in front of the field of view and at the bottom edge two clips are provided in sequence that open downwards. A plastic panel formed in the manner of rimless glasses may be engaged in the clip.

JP 2012 and 046857A discloses a helmet with a panel. Additional panels may be secured to the panels and carry magnets for this purpose.

Disclosure of Invention

It is therefore an object of the present invention to overcome the disadvantages associated with the prior art. In particular, it is intended to provide a protective device which both protects against mechanical influences to a very high level and is particularly user-friendly. It is also intended to provide corresponding additional grille elements. Furthermore, it is also intended to provide a corresponding protective helmet.

Detailed Description

Referring first to figures 1, 2, a forestry worker safety helmet comprises a dished helmet shell 1 and a face-protecting means 2 arranged on the helmet shell 1.

The helmet shell 1 is formed rigidly and preferably from a plastic material. It is intended to cover the head of a helmet wearer.

On the helmet shell 1, in each case a carrying arm 3 is arranged, which carrying arm 3 can be moved, in particular pivoted and/or displaced, relative to the helmet shell 1 and carries the face protection 2. Advantageously, the facing device 2 can then be pivoted relative to the carrier arm 3. It is movable as a whole between a lower protection position, shown in figure 1, and an upper parking position (not shown). In use, the face protection 2 in its protective position is protectively positioned in front of the face of the helmet wearer and is transparent, the face protection being moved upwards away from the face of the helmet wearer when in its parking position.

The covering device 2 comprises a covering element 4, which is in this case designed as a full-face covering element and is formed from a transparent, impact-resistant plastic material. The shield element 4 has a closed shield 5 and two bearing devices 6 arranged laterally at the top. The sheeting 5 provides a viewing area.

Furthermore, the shield element 4 has a transverse plate 7, which transverse plate 7 adjoins the upper edge 8 of the shield 5 and projects at a position opposite to the viewing direction 9 of the facing device 2, that is to say towards the rear or towards the inside. The transverse plate 7 extends substantially between the bearing means 6.

The bearing device 6 is designed as a bearing opening, which is substantially circular and closed circumferentially.

In the assembled state of the shield element 4, a bearing member arrangement 10 extends through each bearing arrangement 6, which also extends through a respective bearing hole 11 in the respective carrier arm 3 and defines a pivot axis, which bearing hole is closed on the circumferential side. The shield element 4 is connected in an articulated manner to the carrying arm 3 and thus to the helmet shell 1 via a bearing member arrangement 10.

Furthermore, the cladding device 2 comprises an additional grille element 12 which is arranged in the assembled state on the outside relative to the panel element 4. The additional grille elements 12 are constructed as full-face additional grille elements. It has a grid area 13 and a frame part 14, said frame part 14 extending completely around the grid area 13/enclosing the grid area 13. The grid region 13 is formed by a grid (mesh). The grid formed by the grid region 13 advantageously has a grid width (openings/cm) of between 10 and 50, in particular between 15 and 40²). The light transmittance is preferably between 50 and 90%, more preferably between 55 and 80%. The grid region 13 provides a viewing area.

In order to fix the additional grille element 12 locally to the panel element 4, the additional grille element 12 has fixing means, which will be explained in more detail below, in particular with reference to fig. 3, 4 and 6.

As is shown in particular in fig. 3 and 4, the fixing device comprises two magnet fixing devices 15, both of which are arranged laterally with respect to the grid region 13.

Each magnet fixing device 15 has two magnetic elements 16 which are arranged laterally on the frame part 14 and are spaced apart from one another along the frame part 14. Advantageously, the magnetic element 16 is embedded in the frame portion 14. In this case, the magnetic element is arranged on the carrier side or inside of the frame part 14 and is preferably free on the inside.

Adjacent to the magnetic element 16 of each magnet fixture 15, the folding means 17 of the magnet fixture 15 abut the frame portion 14 laterally opposite the grid region 13. Each folding device 17 has a first film hinge 18 adjoining the frame part 14, a spacer plate 19 adjoining the first film hinge 18, a second film hinge 20 adjoining the spacer plate 19 and a holding part 21 adjoining the second film hinge 20.

The partition plate 19 and the holding portion 21 of each folding device 17 are integrally connected to each other. Which are integrally connected to the frame portion 14.

The first film hinge 18 extends partially along the frame portion 14. The film hinges 18, 20 of each folding device 17 extend parallel to each other. Advantageously, for each

film hinge

18, 20, there is a reduced thickness and/or material weakening in order to form a respective pivot axis in each case.

Each spacer plate 19 is rectangular and can pivot about the associated first film hinge 18 relative to adjacent regions of the frame portion 14. Each spacer plate 19 has a width substantially corresponding to the edge-side thickness of the side area of the apron element 4.

Each retaining portion 21 is rectangular and can pivot relative to the adjacent spacer plate 19 via the associated second film hinge 20.

Each holding part 21 carries two magnetic counter-elements 22, which are arranged spaced apart from each other along the holding part 21. The spacing of the magnetic counter-elements 22 of the holding member 21 corresponds to the spacing of the magnetic elements 16 of the magnet fixing device 15.

Each retaining portion 21 is pivotable about the adjacent first film hinge 18 and/or second film hinge 20 between a retaining position (fig. 4) and an assembled/disassembled position (fig. 3, left).

In the retaining position, the screen element 4 is partially closed in this position in the assembled state of the additional grille element 12 between each retaining portion 21 and the respectively adjacent region of the frame part 14. Each retaining portion 21 then extends substantially parallel to the adjacent region of the frame part 14, and the respective magnetic element 16 is magnetically connected with the then opposite magnetic counter-element 22, so that the respective retaining portion 21 is actually retained on the rear side of the apron element 4. The magnetic element 16 and the magnetic counter-element 22 are polarized for this purpose in such a way that they then attract and produce a magnetic connection. The shield elements 4 are arranged between the spacer plates 19. The spacer plates 19 extend in an adjacent manner along the apron element 4 at this location.

In the assembly/disassembly position, which also forms the release position, the respective retaining portion 21 is lifted from the apron element 4 and releases the magnetic connection between the magnetic counter-element 22 and the associated magnetic element 16. The additional grille element 12 can thus be lifted from the screen element 4.

Furthermore, the fastening device has a surrounding receiving member 23 (fig. 6) which is formed in an upper edge region 24 of the frame part 14. The surrounding receiving member 23 is open in the viewing direction 9 of the facing device 2, that is to say, towards the front or outside. It has a locking opening 25 on the upper side.

In the assembled state of the additional grate element 12, the transverse plate 7 engages in the surrounding receiving member 23 in a form-fitting locking manner, wherein a locking projection 26 arranged on top of the transverse plate 7 engages in the locking opening 25 from below in a locking direction. The locking projection 26 has an inclined lead-in member 27, which lead-in member 27 rises from a free rear edge 28 of the transverse plate 7 and is formed with a retaining shoulder 29. The inclined introduction member 27 facilitates the introduction of the transverse plate 7 into the surrounding receiving member 23. The retaining shoulder 29 prevents the locking projection 26 from undesirably releasing the locking connection in the engaged state in the locking opening 25. It then faces, in the engaged state, a wall of the frame part 14, which wall delimits the locking opening 25. Via the locking opening 25, the locking connection can be released again.

A second embodiment of the magnet fixture will be described below with reference to fig. 5, wherein reference will also be made to the previous description.

In contrast to the above-described embodiments, the holding portion 30 projects from the frame portion 14 opposite to the viewing direction 9, that is, toward the rear side or toward the inside, adjacent to the magnetic element 16 of each magnet fixture 15. A displacement element 31 carrying the two magnetic counter-elements 22 is guided, in particular displaceably guided, by each holding portion 30.

In the retaining position, the respective displacement element 31 engages behind the shield element 4 and the magnetic counter element 22 is magnetically connected with the magnetic element 16, the magnetic element 16 then being arranged in an adjacent manner.

In the assembled/disassembled position, the respective displacement element 31 is retracted and the additional grille element 12 can be arranged on the screen element 4 or removed accordingly.
