Description

DESCRIPTION

Visor arrangement

The invention relates to a visor arrangement, in particular for a protective helmet. Furthermore, the invention relates to an additional protective grille element for such a visor arrangement. The invention further relates to a protective helmet comprising such a visor arrangement.

From the prior disclosed use it is known to equip forest workers for their work in the forest with a so-called forest work team. The forestry work team generally comprises a protective work helmet and hearing protectors mounted on it, as well as a mesh visor attached to it for the protection of the forester against flying wood chips that are frequently generated by sawing tree trunks, branches and the like. Disadvantageous in this regard is that the mesh visor does not offer sufficient protection against branches that collide at high speed against the mesh visor. A large part of work accidents in the case of forest workers is due to this.

From the state of the art, shock resistant plastic helmet visors are also known which offer good protection against mechanical influences such as branches. Such helmet visors, however, have the disadvantage that wood chips stick to them during forestry work due to their resin, making it difficult for the forestry worker to see and thus creating a new source of danger.

From US 4,736,466 a generic visor arrangement is known according to the preamble of claim 1.

The visor arrangement comprises a mesh part that can be attached locally by means of a headband around the wearer's head. Attached to the mesh portion is a forehead pad and a chin pad by means of tabs running over wires in the mesh portion. Furthermore, the visor arrangement has an eye screen that is disposed between the mesh portion and the pad in a removable manner. Manipulation of this visor arrangement is often unsatisfactory.

An eye protector known from US 2,655,656 comprises a transparent screen that is in connection with the headband. In the area of the screen, there are a plurality of ventilation openings. A panel with small openings extends on the inner side of the screen and covers the ventilation openings. The panel is made, for example, of wire and is fixed in place by rivets.

DE 29708134 U1 discloses a protective helmet for forestry work comprising a visor that can pivot in front of the face area. The helmet also has a helmet screen that protrudes over the face area, in which two clips open downward sit in the edge area. A plastic disc shaped like rimless glasses can be nailed to the clips.

JP 2012-046857 A discloses a helmet with a panel. An additional panel with magnets can be attached to the panel.

The invention is therefore based on the objective of eliminating the disadvantages associated with the state of the art. In particular, a visor arrangement must be created which, on the one hand, offers very high protection against mechanical influences and, on the other hand, is particularly comfortable for the user. In addition, a corresponding additional protective grille element must be provided. In addition, a corresponding protective helmet must be offered.

This object is achieved according to the invention by means of the characteristics indicated in claims 1, 10 and 11. The core lies in the fact that, in at least one protection panel element, at least one additional protection grid element can be attached. , in particular as a construction piece, for additional protection. Advantageously, the at least one additional protective grille element can be attached locally directly to the at least one protective panel element. This local fixing is preferably possible without tools.

By means of the at least one additional protective grid element, in its assembled state, the at least one protective panel element is securely protected, which ultimately also leads to improved protection of the wearer. In particular, the at least one additional protective grid element effectively prevents, in use, resinous wood chips from being affixed externally to the at least one protective panel element.

By means of the at least one fixing equipment, the at least one additional protective grid element can be fixed particularly securely on the at least one protective panel element. In particular, relative movement between the at least one additional protective grid element and the at least one protective panel element in at least one direction of movement can be avoided in this way. Favorably, between the at least one surrounding housing and the at least one protection panel element, there is an interlocking and / or plug, in particular newly removable.

The visor arrangement is particularly easy for the user to use thanks to at least one magnetic attachment kit. The at least one additional protective grid element can thus be fixed very simply and securely on the at least one protective panel element. This also ensures easy disassembly.

Advantageously, the at least one additional protection grid element has at least one preferably lateral fixing hook for fixing it on the at least one protection panel element.

It is advantageous if the at least one additional protective grid element has at least one grid area and at least one frame part that is in connection with the at least one grid area. The at least one additional protective grille element is favorably made symmetrically.

The at least one additional protective grille element preferably has an opening width of between 10 and 50, in particular between 15 and 40 openings / cm2.

The at least one additional protective grid element is preferably configured as a full-face additional protective grid element.

At least the grid area of the at least one additional protective grid element is preferably formed of a metallic material or a plastic material, for example nylon.

The at least one additional protective grille element is preferably arranged in this visually mounted state of the visor arrangement behind the at least one protective panel element. It is, therefore, particularly arranged externally on the at least one protection panel element. In the carried state, the at least one protective panel element is oriented towards the eyes of the wearer of the visor arrangement, while the at least one additional protective grille element is located on the side opposite the eyes of the visor arrangement. It is convenient if the at least one additional protective grid element in the assembled state covers the at least one protective panel element at least in zones, favorably entirely.

Preferably, at least one additional protective grid element and / or protective panel element is provided with at least one spacer element for the zoned arrangement of the at least one additional protective grid element with respect to the at least one protection panel element. Favorably, by means of the at least one spacer element, it is possible to obtain that the at least one additional protection grid element and the protection panel element in the assembled state run at least in its area of vision distantly, but at least by zones parallel to each other.

The at least one protection panel element is preferably made symmetrically. It preferably provides high protection against large and / or heavy flying bodies such as branches. It is advantageous if the at least one protection panel element is formed of plastic, in particular impact resistant plastic. The at least one protection panel element is preferably transparent. It may be tinted. Favorably, the at least one protection panel element is made as a full face protection panel element or as an eye protection panel element.

It is advantageous if exactly one protection panel element and / or additional protection grid element is present.

The protective helmet is intended in particular for forest workers. Alternatively, other purposes of use are possible. Favorably, it is made symmetrically with respect to a plane of symmetry. It is advantageous if a lining is provided on the helmet cap.

Other advantageous designs of the invention are indicated in the dependent claims.

The design according to dependent claim 2 allows easy removal, in particular without tools, of the visor arrangement, such that, for example, the at least one additional protective grille element and / or the at least one Protection panel element can or can be easily replaced or individually cleaned.

The design according to dependent claim 3 allows a secure connection between the at least one additional protective grid element and the at least one protective panel element. Preferably, between these, in the assembled state of the visor arrangement, there is a connection both by force dragging and shape dragging, which leads to a very high operating safety.

The at least one magnetic element, according to dependent claim 4, is preferably a permanent magnet. The at least one complementary magnetic element is favorably made as a permanent magnet or as a ferromagnetic element. Alternatively, a reverse arrangement of magnetic element and complementary magnetic element is possible.

The design according to dependent claim 6 leads to a very secure connection between the at least one additional protection grid element and the at least one protection panel element. Favorably, the at least one protection panel element is free of the magnetic element (or of magnetic elements) or of the complementary magnetic element (or complementary magnetic elements).

The design according to dependent claim 7 again allows a very secure and long-lasting connection between the at least one protection panel element and the at least one additional protection grid element. The at least one folding arrangement preferably has at least one favorably integral hinge, hinge or the like. It is advantageous if at least one spacer rib and / or retention rib of the at least one folding arrangement is joined or are joined in one piece and hingedly with at least one frame part of the at least one protective grid element additional.

Figure 4 an enlarged partial fragment of Figure 3 illustrating the attachment of the additional protective grille element to a protective panel element of the visor arrangement,

FIG. 5 a partial fragment corresponding to FIG. 4 showing the attachment of an additional protection grid element to a protection panel element according to a second embodiment according to the invention of the visor arrangement, and

Figure 6 an enlarged partial fragment illustrating another attachment of the additional protective grid element shown in Figures 1 to 5 on the protective panel element.

Firstly, referring to Figures 1,2, a protective helmet for forestry work comprises a cup-shaped helmet cap 1 and a visor arrangement 2 which is arranged on the helmet cap 1.

Helmet cap 1 is rigidly and preferably configured of a plastic material. It serves to cover the head of a helmet wearer.

In the helmet cap 1, a support arm 3 is arranged laterally in each case, which is movable with respect to the helmet cap 1, in particular pivoting and / or movable, and supports the visor arrangement 2. The visor arrangement 2 in turn can pivot favorably with respect to the support arms 3. It can be moved as a whole between a lower guard position shown in Figure 1 and an upper parking position (not shown). In use, the visor arrangement 2 which is in the protection position is facing the face of the helmet wearer protecting it and is translucent, while, in its parking position, it is removed from the face of the helmet wearer facing up .

The visor arrangement 2 comprises a protection panel element 4 which in this case is made as a full face protection panel element and is formed of a shock resistant plastic. The protection panel element 4 has a closed protection panel 5 and two mounting agents 6 arranged laterally on top. Protection panel 5 offers an area of visibility.

Furthermore, the protection panel element 4 has a transverse rib 7 that follows an upper edge 8 of the protection panel 5 and at that point protrudes against a visual direction 9 of the visor arrangement 2, it is say backwards or inwards. The transverse rib 7 extends essentially between the mounting agents 6.

The mounting agents 6 are made as mounting openings which are essentially circular and perimeter closed.

In the mounted state of the protection panel element 4, each mounting agent 6 is traversed by a mounting body arrangement 10 that also passes through a corresponding closed and perimeter mounting hole 11 in the corresponding support arm 3 and defines an axis pivoting. By means of the mounting body arrangements 10, the protection panel element 4 is articulately connected with the support arms 3 and, therefore, with the helmet cap 1.

Furthermore, the visor arrangement 2 comprises an additional protection grid element 12 which is arranged in the state externally mounted to the protection panel element 4. The additional protection grid element 12 is made as an additional protection grid element of full face. It has a grid area 13 and a frame part 14 that completely runs / surrounds the grid area 13. The grid area 13 is formed by a (grid) grid. The meshes formed by the grid area 13 favorably have a mesh width of between 10 and 50, in particular between 15 and 40 openings / cm2. The light transmission is preferably between 50 and 90%, more preferably between the 55 and 80%. Grille area 13 offers an area of visibility.

For local fixing of the additional protection grid element 12 to the protection panel element 4, the additional protection grid element 12 has a fixing arrangement which will be discussed in more detail below, in particular with reference to the Figures 3, 4 and 6.

As illustrated in particular in Figures 3, 4, the fixing arrangement comprises two magnetic fixing kits 15 which are arranged laterally in each case to the grid area 13.

Each magnetic fixing kit 15 has two magnetic elements 16 which are arranged laterally on the frame part 14 and spaced apart from each other along the same. Favorably, the magnetic elements 16 are embedded in the frame part 14. In this regard, they are arranged on the support side or internally in the frame part 14 and are preferably located internally free.

Adjacent to the magnetic elements 16 of each magnetic fixing equipment 15, a folding arrangement 17 of the magnetic fixing equipment 15 is attached laterally to the frame part 14, opposite the grid area 13. a first film hinge 18 attaching to frame portion 14, a spacer rib 19 attaching to first film hinge 18, a second film hinge 20 attaching to spacer rib 19, and a retaining piece 21 which is attached to the second film hinge 20.

The spacer rib 19 and the retaining part 21 of each folding arrangement 17 are joined together in one piece. They are joined in one piece with the frame part 14.

The first film hinges 18 extend in zones along the frame part 14. The film hinges 18, 20 of each folding arrangement 17 run parallel to each other. Favorably, in each film hinge 18, 20 there is a reduced thickness and / or weakening of the material to each form a corresponding pivoting axis.

Each spacer rib 19 is rectangular and can pivot about the corresponding first film hinge 18 with respect to an adjacent region of frame part 14. Each spacer rib 19 has a width that essentially corresponds to a thickness of the edge side. of a lateral area of the protection panel element 4.

Each retaining part 21 is rectangular and can pivot by means of the corresponding second film hinge 20 with respect to the adjacent spacer rib 19.

Each retaining part 21 carries two complementary magnetic elements 22 that are arranged spaced apart from one another along the retaining part 21. The distance of the complementary magnetic elements 22 from a retaining part 21 corresponds to the distance of the magnetic elements 16 of a magnetic fixing kit 15.

Each retaining part 21 can pivot between a retaining position (Figure 4) and a mounting / demounting position (Figure 3, left) around the adjacent first film hinge 18 and / or the second film hinge 20.

In the retained position, in the assembled state of the additional protective grid element 12, between each retaining piece 21 and a corresponding adjacent zone of the frame part 14, the protective panel element 4 is zoned. retaining piece 21 runs essentially parallel to an adjacent area of frame part 14 and the respective magnetic elements 16 are in magnetic connection with the Opposite complementary magnetic elements 22, in such a way that the respective retaining part 21 is practically fastened on the rear side in the protection panel element 4. The magnetic elements 16 and the complementary magnetic elements 22 are thereby polarized in this way that these attract each other and a magnetic bond occurs. The protective panel element 4 is disposed between the spacer ribs 19. The spacer ribs 19 extend there adjacently along the protective panel element 4.

In the assemble / disassemble position, which also forms a release position, the corresponding retaining part 21 is lifted from the protective panel element 4 and the magnetic connection between the complementary magnetic elements 22 and the respective magnetic elements 16 has been dissolved . The additional protection grid element 12 can therefore be lifted from the protection panel element 4.

Furthermore, the fixing arrangement has a surrounding housing 23 (Figure 6) which is configured in an upper edge area 24 of the frame part 14. The surrounding housing 23 is open in the visual direction 9 of the visor arrangement 2, it is say forward or outward. It has an interlocking opening 25 above.

In the assembled state of the additional protective grille element 12, the transverse rib 7 penetrates, in particular in a form-fitting manner, into the surrounding housing 23, whereby an interlocking bead 26 is disposed above on the transverse rib 7 from below in the interlocking opening 25. The interlocking bead 26 has an inlet bevel 27 which rises from a rear free edge 28 of the transverse rib 7 forming a retaining shoulder 29. The inlet bevel 27 facilitates the entry of the transverse rib 7 into the surrounding housing 23. Retaining shoulder 29 prevents in the locked state of the locking bead 26 in the locking opening 25 an unintentional release of the locking joint. It is oriented, in the latched state, to a wall of the frame part 14 that delimits the latch opening 25. By means of the latch opening 25, the latch joint can be removed again.

Next, with reference to figure 5, a second embodiment of the magnetic fixing equipment is described, referring also to the previous description.

Contrary to the previous embodiment, a fastening element 30 protrudes adjacent to the visual direction 9, that is to say, towards the rear or towards the magnetic elements 16 of each magnetic fixing equipment 15 of the frame part 14. inside. By means of each clamping element 30, a displacement element 31 is guided, particularly in a displaceable manner, which carries the two complementary magnetic elements 22.

In the retention position, the corresponding displacement element 31 engages behind the protection panel element 4 and the complementary magnetic elements 22 are in magnetic connection with the adjacent magnetic elements 16.

In the assemble / disassemble position, the corresponding displacement element 31 is retracted and enables the provision of the additional protection grid element 12 in the protection panel element 4 or the corresponding removal.
