technical field

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

Background technique

It is previously known from public prior use to provide so-called forestry equipment for forestry workers working in forests. Forester equipment typically includes a work safety helmet with ear protectors mounted on said work safety helmet and a grid visor attached to said work safety helmet to protect the forester from encounters when sawing tree trunks, branches, etc. Flying wood chips are often generated when waiting. In this case, it is disadvantageous that the grid armor does not adequately protect against tree branches hitting the grid armor at high speed. Most industrial accidents among forestry workers can be attributed to this.

Helmet visors of shock-resistant plastic material are also known from the prior art, which provide good protection against mechanical influences, such as tree branches. However, a disadvantage of such helmet visors is that the wood chips, due to their resin, bind together during forestry work, which impairs the forestry worker's vision and thus leads to a new source of danger.

DE 297 08 134 U1 discloses a forestry worker's safety helmet comprising a visor that can be pivoted in front of the field of view. The helmet also has a helmet screen which protrudes in front of the field of view and which is provided in turn with two clips opening downwards at the bottom edge. Plastic panels formed in the manner of rimless glasses can be engaged in the clips.

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

Contents of the invention

It is therefore an object of the present invention to overcome the disadvantages associated with the prior art. In particular, the aim is to provide a facing device which combines an extremely high level of protection against mechanical influences and which is also particularly user-friendly. It is also intended to provide corresponding additional grille elements. In addition, a corresponding protective helmet is also intended.

This object is achieved according to the invention by the features stated in claims 1 , 11 and 12 . The core concept relates to at least one additional grille element, in particular as an accessory, which can be fixed to at least one panel for additional protection. Advantageously, at least one additional grille element can be locally fixed directly to the at least one fascia element. Such local fixation is preferably possible without tools.

Due to the at least one additional grille element, the at least one panel element is securely protected in its assembled state, which ultimately also leads to better protection for the wearer. In particular, the at least one additional grille element then effectively prevents resin-oozing wood chips from adhering to the outside of the at least one fence element during use.

Due to the at least one fixing device, at least one additional grille element can be fixed to the at least one panel element in a particularly secure manner. In particular, a relative movement between the at least one additional grille element and the at least one cover element can thus be prevented in at least one direction of movement.

It is advantageous if the at least one additional grille element in the assembled state at least partially, advantageously completely covers the at least one covering element.

Preferably, at least one spacing element is arranged on the at least one additional grille element and/or the trim element for a partial spacing of the at least one additional grille element relative to the at least one trim element. Advantageously, due to the at least one spacer element, the at least one additional grille element and the cover element in the connected state at least in their viewing range can extend at a distance, but at least partially parallel to each other.

The at least one trim element is preferably configured symmetrically. It preferably ensures a high level of protection against flying large and/or heavy components such as tree branches. It is advantageous if at least one trim element is formed from a plastic material, in particular an impact-resistant plastic material. At least one covering element is preferably transparent. It can be colored. Advantageously, at least one visor element is designed as an overall face visor element or as an eye visor element.

Preferably, in the assembled state of the facing arrangement, there is a non-positive locking and a positive locking connection between these components relative to each other, which leads to an extremely high level of operational reliability.

The facing device according to the dependent claim 4 is particularly user-friendly. Thus, at least one additional grille element can be locally fixed to the at least one fascia element in an extremely simple and safe manner. Thus, simple disassembly is also ensured.

At least one magnetic element according to dependent claim 5 is preferably a permanent magnet. The at least one magnetic counter-element is then advantageously designed as a permanent magnet or as a ferromagnetic element. Alternatively, transposed arrangements of magnetic elements and magnetic counterpart elements are also possible.

An embodiment according to the dependent claim 7 enables an extremely secure connection between at least one additional grille element and at least one panel element. Advantageously, at least one of the fender elements is free of magnetic elements or magnetic counterpart elements.

Detailed ways

Referring first to FIGS. 1 and 2 , a forest worker safety helmet includes a disc-shaped helmet shell 1 and a face shield 2 arranged on the helmet shell 1 .

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

Carrying arms 3 are respectively arranged on the helmet shell 1 , which can be moved, in particular pivoted and/or displaced relative to the helmet shell 1 , and which carry the visor device 2 . Advantageously, the facing device 2 can then pivot relative to the carrying arm 3 . It is integrally movable between a lower protection position shown in FIG. 1 and an upper parking position (not shown). In use, the visor 2 is protectively positioned in front of the helmet wearer's face and is transparent in the protective position, and in its parked position the visor 2 is moved upwards away from the helmet wearer's face.

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

Furthermore, the covering element 4 has a transverse plate 7 which adjoins the upper edge 8 of the covering 5 and protrudes at a position opposite to the viewing direction 9 of the facing arrangement 2 , that is to say towards the rear or towards the Prominent on the inside. The transverse plates 7 extend substantially between the bearing arrangements 6 .

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

In the assembled state of the fender element 4, a bearing member arrangement 10 extends through each bearing arrangement 6, which also extends through a corresponding bearing hole 11 in the corresponding carrier arm 3 and defines a pivot axis, the bearing holes being at Close sideways. The fender element 4 is connected in an articulated manner to the carrier arm 3 and thus to the helmet shell 1 via a bearing component arrangement 10 .

Furthermore, the facing arrangement 2 comprises an additional grille element 12 which, in the assembled state, is arranged on the outside with respect to the covering element 4 . The additional grille element 12 is designed as an additional grille element of the entire face. It has a grid area 13 and a frame part 14 which extends/encloses the grid area 13 completely around the grid area 13 . The grid area 13 is formed of a grid (net). The grid formed by grid regions 13 advantageously has a grid width (openings/cm ² ) of between 10 and 50, in particular between 15 and 40. The light transmittance is preferably between 50 and 90%, more preferably between 55 and 80%. The grid area 13 provides a viewing area.

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

As shown in particular by FIGS. 3 , 4 , the fastening device comprises two magnet fastening devices 15 , both of which are arranged laterally with respect to the grid area 13 .

Each magnet fixture 15 has two magnetic elements 16 which are arranged laterally on the frame part 14 and are spaced apart from each other along the frame part 14 . Advantageously, the magnetic element 16 is embedded in the frame part 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 holder 15 , the fold means 17 of the magnet holder 15 adjoins the frame part 14 laterally opposite the grid region 13 . Each folding device 17 has a first film hinge 18 adjoining the frame portion 14 , a spacer 19 adjoining the first film hinge 18 , a second film hinge 20 adjoining the spacer 19 and a retaining portion 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. They are integrally connected to the frame portion 14 .

The first film hinge 18 extends partially along the frame part 14 . The film hinges 18 , 20 of each folding device 17 run parallel to one another. Advantageously, for each film hinge 18 , 20 there is a reduced thickness and/or material weakening in order to form in each case a respective pivot axis.

Each spacer panel 19 is rectangular and can pivot about an associated first film hinge 18 relative to an adjacent area of the frame part 14 . Each spacer web 19 has a width which substantially corresponds to the edge-side thickness of the side regions of the trim element 4 .

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

Each holding part 21 carries two magnetic counterpart elements 22 which are arranged spaced apart from one another along the holding part 21 . The pitch of the magnetic counterpart elements 22 of the holding member 21 corresponds to the pitch of the magnetic elements 16 of the magnet holder 15 .

Each holding portion 21 is pivotable about the adjacent first film hinge 18 and/or second film hinge 20 between a holding position ( FIG. 4 ) and an assembly/disassembly position ( FIG. 3 , left).

In the holding position, in the assembled state of the additional grille element 12 between each holding portion 21 and the respective adjacent region of the frame portion 14 , the covering element 4 is partially closed in this position. Each retaining portion 21 then extends substantially parallel to an adjacent region of the frame portion 14, and the corresponding magnetic element 16 is magnetically connected to the then opposing magnetic counterpart element 22, so that the respective retaining portion 21 is actually retained on the fender. Rear side of element 4. For this purpose, the magnetic element 16 and the magnetic counterpart element 22 are polarized in such a way that they then attract and create a magnetic connection. The trim elements 4 are arranged between the spacer plates 19 . In this position, the spacer webs 19 extend adjacently along the trim element 4 .

In the assembly/disassembly position, which also forms the release position, the corresponding retaining portion 21 is lifted out of the trim element 4 and the magnetic connection between the magnetic counterpart element 22 and the associated magnetic element 16 is released. As a result, the additional grille element 12 can be lifted out of the trim element 4 .

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

In the assembled state of the additional grille element 12 , the transverse plate 7 engages in the surrounding receiving member 23 , in particular in a form-fit locking manner, wherein a locking projection 26 arranged at the top of the transverse plate 7 engages from below in the locking opening 25 The locking side engages. The locking protrusion 26 has an inclined lead-in member 27 rising from the free rear edge 28 of the transverse plate 7 and 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 undesired release of the locking connection in the engaged state of the locking projection 26 in the locking opening 25 . It then faces, in the engaged state, the wall of the frame part 14 delimiting the locking opening 25 . Via the locking opening 25 the locking connection can be released again.

A second embodiment of the magnet fixing device will be described below with reference to FIG. 5 , wherein reference is also made to the previous description.

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

In the holding position, the corresponding displacement element 31 engages behind the trim element 4 and the magnetic counterpart element 22 is magnetically connected to the magnetic element 16 , which is then arranged adjacently.

In the assembly/disassembly position, the respective displacement element 31 is retracted and the additional grille element 12 can be placed on the trim element 4 or removed accordingly.
