The present patent application claims the priority of German patent application DE 10 2016 205 448.1, the content of which is incorporated herein by reference.

The invention relates to a sighting arrangement, in particular for a protective helmet. Furthermore, the invention is directed to an additional protective grid element for such a sighting arrangement. The invention also relates to a protective helmet comprising such a sighting arrangement.

It is already known from prior public use to equip forest workers for their work in the forest with a so-called forest worker's set. The forestry worker's kit generally includes a safety helmet and hearing protectors attached thereto, and a grating visor connected thereto to protect the forest worker from flying wood chips that are often produced when sawing tree trunks, branches or the like. The disadvantage here is that the grating visor does not provide sufficient protection against branches that hit the grating visor at high speed. Much of the work-related accidents among forestry workers are due to this.

Helmet visors made of impact-resistant plastic are known from the prior art, which provide good protection against mechanical influences, such as branches. However, such helmet visors have the disadvantage that sticking to them in forest work wood chips because of their resin, which affects the view of the forest worker and thus provides a new source of danger. From DE 297 08 134 Ul a forest worker protective helmet is known, which includes a visor pivotable in front of a field of vision. The helmet also has a projecting over the field of vision helmet shield, in turn, sitting at the bottom of two downwardly open clips. In the clips, a shaped like a stunned glasses plastic disc is latched.

JP 2012-046857 A discloses a helmet with a disk. On the disc an additional disc is fastened, which carries magnets.

The invention is therefore based on the object to overcome the disadvantages associated with the prior art. In particular, a sighting is to be created, on the one hand offers extremely high protection against mechanical influences and on the other hand is particularly user-friendly. A corresponding additional protective grid element should also be provided. Furthermore, a corresponding protective helmet should be delivered. This object is achieved by the features specified in the claims 1, 1 1 and 12 features. The core is that at least one additional protective grid element, in particular as an attachment, for additional protection can be fastened to at least one protective disk element.

Hereinafter, two preferred embodiments of the invention will be described by way of example with reference to the accompanying drawings. 1 shows a perspective view of a protective helmet with a visor arrangement of the invention arranged in a protective position,

FIG. 2 shows an exploded view of the protective helmet shown in FIG. 1, an exploded view of the visor assembly shown in Figures 1 and 2, Figure 4 is an enlarged partial section of Figure 3, illustrating the definition of an additional guard element on a protective element of the visor assembly, a section corresponding to Figure 4, the determination of an additional guard element on a protective screen element according to a second embodiment of the visor assembly according to the invention, and an enlarged partial section illustrating a further definition of the additional protective grid element shown in Figures 1 to 5 on the protective disk element.

Referring first to FIGS. 1, 2, a forestry protective helmet comprises a shell-like helmet dome 1 and a sighting arrangement 2, which is arranged on the helmet dome 1.

The helmet shell 1 is rigid and preferably made of plastic material det. It serves to cover the head of a helmet wearer.

On the helmet shell 1, a support arm 3 is laterally arranged in each case, which is movable relative to the helmet shell 1, in particular pivotable and / or displaceable, and carries the sighting arrangement 2. The sighting arrangement 2 in turn is advantageously pivotable relative to the support arms 3. It is in its entirety between one shown in FIG lower guard position and an upper parking position (not shown) movable. In use, the visor assembly 2 in the protective position is protectively in front of the face of the helmet wearer and can be seen through, while in its parking position it is then moved upwards away from the face of the helmet wearer.

The sighting arrangement 2 comprises a protective disk element 4, which is embodied here as a full-face protective disk element and is formed from transparent, impact-resistant plastic. The protective disk element 4 has a closed protective disk 5 and two bearing means 6 arranged laterally at the top. The protective disk 5 offers a viewing area.

Furthermore, the protective disk element 4 has a transverse web 7, which adjoins an upper edge 8 of the protective disk 5 and projects there against a viewing direction 9 of the sighting arrangement 2, that is to say in the rearward or inward direction. The crossbar 7 extends substantially between the bearing means 6.

The bearing means 6 are designed as bearing openings, which are substantially circular and circumferentially closed.

In the assembled state of the protective disk element 4, each bearing means 6 is penetrated by a bearing body assembly 10, which also penetrates a corresponding, circumferentially closed bearing bore 1 1 in the corresponding support arm 3 and defines a pivot axis. About the bearing body assemblies 10, the shield member 4 is pivotally connected to the support arms 3 and so with the helmet shell 1. Furthermore, the sighting arrangement 2 comprises an additional protective grid element 12, which is arranged in the mounted state on the outside to the protective screen element 4. The additional protective grid element 12 is designed as a full-face additional protective grid element. It has a grid area 13 and a frame part 14 which completely surrounds / surrounds the grid area 13. The grid area 13 is formed by a grid (net). Meshes formed by the mesh region 13 favorably have a mesh size that is between 10 and 50, in particular 15 and 40, openings / cm ² . A light transmission is preferably between 50 and 90%, more preferably between 55 and 80%. The grid area 13 provides a viewing area.

For locally fixing the additional protective grid element 12 to the protective screen element 4, the additional protective grid element 12 has a fixing arrangement, which will be discussed in more detail below, in particular with reference to FIGS. 3, 4 and 6.

As illustrated in particular FIGS. 3, 4, the fixing arrangement comprises two magnet-fixing devices 15, which are each arranged laterally 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 spaced from each other along the same. Conveniently, the magnetic elements 16 are embedded in the frame part 14. They are arranged on the carrier side or on the inside of the frame part 14 and are preferably exposed on the inside.

Adjacent to the magnetic elements 16 of each magnet-fixing device 15, a folding arrangement 17 of the magnetic field adjoins the frame part 14 opposite the grid area 13 laterally. Fixing device 15 at. Each folding arrangement 17 has a first film hinge 18 adjoining the frame part 14, a spacing web 19 adjoining the first film hinge 18, a second film hinge 20 adjoining the spacing web 19 and a retaining part 21 adjoining the second film hinge 20.

The spacer web 19 and the retaining member 21 of each folding assembly 17 are integrally connected. They are integrally connected to the frame part 14.

The first film hinges 18 extend in regions along the frame part 14. The film hinges 18, 20 of each folding arrangement 17 are parallel to each other. Conveniently, each film hinge 18, 20 has a reduced thickness and / or material weakening in order to form a respective pivot axis.

Each spacer web 19 is rectangular and can be pivoted about the associated first film hinge 18 with respect to an adjacent region of the frame part 14. Each spacing web 19 has a width which substantially corresponds to a peripheral thickness of a side region of the protective disk element 4.

Each retaining part 21 is rectangular in shape and can be swiveled over the associated second film hinge 20 with respect to the adjacent spacer web 19.

Each retaining member 21 carries two counter-magnet elements 22 which are spaced from each other along the retaining member 21 are arranged. From the- is the counter-magnetic elements 22 of a retaining member 21 corresponds to the distance of the magnetic elements 16 of a magnetic fixing device 15th

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

In the retaining position, in the assembled state of the additional protective screen element 12, between each retaining part 21 and a corresponding adjacent area of the frame part 14, the protective screen element 4 is enclosed in regions. Each retaining part 21 then runs essentially parallel to an adjacent region of the frame part 14 and the respective magnetic elements 16 are in magnetic connection with the then opposing magnetic elements 22, so that virtually the respective retaining part 21 is held on the protective disk element 4 at the back. The magnetic elements 16 and the counter-magnetic elements 22 are poled so that they then tighten and a magnetic connection is formed. The protective disk element 4 is arranged between the spacer webs 19. The spacing webs 19 extend adjacent thereto along the protective disk element 4.

In the assembly / disassembly position, which also forms a release position, the respective retaining part 21 is lifted off the protective disk element 4 and the magnetic connection between the countermagnetic elements 22 and the associated magnetic elements 16 is dissolved. The additional protective disk element 12 can thus be lifted off the protective disk element 4. Furthermore, the fixing arrangement has a gripping receptacle 23 (FIG. 6), which is formed in an upper edge region 24 of the frame part 14. The Umgreifaufnahme 23 is in the direction of 9 of the visor assembly 2, ie forward or outside, open. It has a latching opening 25 above.

In the assembled state of the additional protection disc member 12 of the crossbar 7 engages, in particular form-fitting, in the Umgreifaufnahme 23, in which case a top arranged on the cross bar 7 locking lug 26 engages from below into the latching opening 25 latching. The locking lug 26 has an insertion bevel 27, which rises from a free rear edge 28 of the transverse web 7 to form a retaining shoulder 29. The insertion bevel 27 facilitates insertion of the transverse web 7 in the Umgreifaufnahme 23. The retaining shoulder 29 prevents in the locked state of the locking lug 26 in the locking opening 25 an unwanted solution of the locking connection. It is then in the locked state of a locking opening 25 delimiting wall of the frame member 14 faces. About the detent opening 25, the locking connection is releasable again. Hereinafter, a second embodiment of the magnetic locking devices will be described with reference to Figure 5, with reference also to the previous description.

In contrast to the previous embodiment, adjacent to the magnetic elements 16 of each magnet-fixing device 15 of the frame part 14, a holding part 30 against the viewing direction 9, ie backwards or inwards, before. Through each holding member 30, a displacement element 31, in particular displaceably guided, which carries the two counter-magnetic elements 22. In the retaining position, the respective displacement element 31 engages behind the protective disk element 4 and the counter-magnetic elements 22 are in magnetic connection with the magnetic elements 16 which are then arranged adjacently.

In the assembly / disassembly position, the respective displacement element 31 is retracted and allows the arrangement of the additional protection grid element 12 on the protective screen element 4 and the corresponding distance.
