Definitions
- the invention relates to a visor mechanism for a protective helmet with the Merkma len of the preamble of claim 1 and a protective helmet with such a visor mechanism.
- Protective helmets especially for use by the police or other emergency services, are primarily used to protect the wearer from the risk of mechanical injury.
- they also regularly have a visor with a transparent pane, which can be folded down if necessary to protect the face and then in particular protects the wearer from hits in the face area or thrown objects.
- laser pointers with high power in particular represent a new source of danger for police and other emergency services, whose defense has so far rarely been considered in the standard equipment of police officers.
- a suitable means of protection against laser beams are panes with special optical properties that can be placed in front of the eyes as a visor.
- the object of the invention is therefore to further develop and improve a visor mechanism known from the prior art for a protective helmet so that the visor or the laser protection can be quickly and reliably brought into the protective position if possible, do not move it unintentionally from this position.
- the proposed visor mechanism is for a protective helmet, which can in particular be a protective helmet for emergency services.
- the proposed before visor mechanism has a visor, which is used to cover a
- the front area of the protective helmet is mounted displaceably to an outer shell of the protective helmet, and a visor adjuster which is coupled to the visor in such a way that the visor can be displaced by pushing the visor adjuster.
- a front area of the protective helmet is to be understood as the open area in front which corresponds to the face area and in particular the eye area of a wearer of the protective helmet. When sliding actuation, it can basically be any type of actuation of the visor adjuster.
- the proposed visor mechanism is characterized in that the visor mechanism has a locking arrangement coupled to the visor and the visor adjuster, which locking arrangement blocks a shift of the visor in a locked state and which locking arrangement allows the visor to be shifted in a released state.
- the proposed visor mechanism is further characterized in that the locking arrangement can be brought into the release state by actuating the visor adjuster to release it.
- the locking arrangement can therefore alternately assume a locking state and a release state. In addition to the locked state and the state of release, there can also be other states that the locking arrangement can take.
- the release actuation can in principle be any type of actuation of the visor adjuster. Blocking the shifting of the visor also blocks the shifting of the visor adjuster.
- the locking arrangement preferably provides a chain of force effects from the visor adjuster to the visor. This is different from a mechanism in which a pretensioned spring is unlocked, for example by actuating the visor adjuster, which then moves the visor.
- a preferred embodiment of the visor mechanism is characterized in that the visor mechanism has a cover for a fixed arrangement on the outer shell.
- the visor is mounted displaceably relative to the cover.
- the visor adjuster is mounted so as to be slidable to cover.
- Another preferred embodiment of the visor mechanism is characterized in that the visor is arranged under the cover and the visor adjuster is arranged on the cover.
- This preferred embodiment corresponds to an arrangement of the visor between the cover and the outer shell and an arrangement of the visor adjuster in such a way that the cover is arranged between the visor adjuster and the outer shell. In this way, both good manual accessibility of the visor adjuster and protection of the visor in the retracted state are achieved.
- the visor and / or the visor adjuster are preferably shifted essentially along a surface of the cover. This means in particular that the shift does not have to take place along a straight path, but can also describe a curve. In particular, it can be the case that a displacement of the visor adjuster and, alternatively or additionally, a displacement of the visor essentially follows a circular path or some other curve.
- the locking arrangement jumps back into the locking state after the release actuation has ended.
- the locking arrangement is "pretensioned" to the locking state.
- reliable locking of the visor is always provided when the release actuation is not being carried out
- the spring arrangement is set up to bring the locking arrangement into the locked state in the absence of an opposing action - for example through the release actuation.
- the locking arrangement has a slide guide arranged in a stationary manner relative to the outer shell and a displacement element coupled to the visor adjuster and received by the slide guide.
- a displacement element coupled to the visor adjuster and received by the slide guide.
- the displacement element can in particular be coupled to the visor adjuster in such a way that the adjustment Sliding element is carried along by the visor adjuster during a shift.
- the displacement element has a blocking element, which blocking element engages positively in the cover in the locked state to block the displacement of the visor.
- the blocking element is received by the slide guide as part of the slide element.
- the blocking element is preferably a substantially semi-cylindrical projection.
- a preferred embodiment of the visor mechanism is characterized in that the cover has a plurality of blocking structures which are each designed to receive the blocking element. Accordingly, the multitude of blocking structures are each essentially semi-cylindrical recesses. Such a configuration ensures that the blocking element regularly slides into one of the two blocking structures even in an intermediate position between two blocking structures. It can also be the case that the blocking structures are arranged along a displacement path of the displacement element. It is preferred that the blocking structures are arranged adjacent to one another essentially one behind the other. In this way there are no gaps between the individual blocking structures. It is further preferred that each blocking structure defines a respectively different displacement position of the displacement element. The blocking structures are preferably arranged on a side of the cover facing the outer shell.
- the visor mechanism is characterized in that the spring arrangement is designed to pretension the blocking element in the direction of the blocking structures. It is also preferred that the displacement element is set up to release the blocking element from the blocking structures upon a release actuation of the visor adjuster. It is preferred that the displacement element has a cross member which is arranged between the outer shell and the spring arrangement and which is directed to exert a tensile force on the spring arrangement in the direction of the outer shell upon the release actuation. This tensile force on the spring assembly can also be described in their direction as opposite to the direction towards the blocking structures.
- a preferred embodiment of the visor mechanism is characterized in that the release actuation is a pressure actuation of the visor adjuster essentially perpendicularly in the direction of the outer shell.
- the release actuation is a pressure actuation of the visor adjuster essentially perpendicularly in the direction of the outer shell.
- the sliding actuation is an actuation of the visor adjuster essentially along the outer shell.
- the visor can be an integral part.
- the visor mechanism it is provided that the visor has an at least semi-transparent pane.
- the disk represents that part of the visor which can be moved in front of the eyes of a wearer of the protective helmet. It is given before that the disk is preferably fastened by a form fit to a carrier part of the displacement element.
- a preferred embodiment of the visor mechanism is characterized in that the visor has a laser protection pane to protect the eyes from laser beams. It is preferred that the pane is the laser protection pane.
- the disc has at least one disc mounting device and the carrier part has a carrier mounting device corresponding to the disc mounting device, the disc mounting device and the carrier mounting device for producing a form-fitting handle are set up with each other.
- the disk assembly device and the carrier assembly device are set up to produce a snap-in connection with one another.
- the carrier mounting device has a mounting opening and the pane mounting device has a projection for snapping into the mounting opening.
- the disc mounting device has a mounting opening and the Carrier mounting device has a projection for locking into the Montageöff voltage.
- the visor adjuster can be operated to move the visor in any direction.
- the visor adjuster in particular when the cover is fixedly arranged on the outer shell, is essentially displaceable along a central axis in the longitudinal direction of the protective helmet.
- the slide guide is arranged essentially around an apex of the outer shell. This ensures that the visor adjuster can be easily reached manually, even if the wearer of the protective helmet is wearing gloves.
- a preferred embodiment of the visor mechanism is characterized in that the visor can be displaced by directly actuating the visor.
- Such direct actuation of the visor is therefore a manual intervention by the wearer of the protective helmet with the visor.
- the visor is displaceable by direct actuation of the visor when the Arre animal arrangement is in the release state.
- the locking arrangement preferably blocks the displacement of the visor by direct actuation of the visor when the locking arrangement is in the locked state.
- the cover has a plurality of openings for fastening the cover to the outer shell. These openings can in particular serve to accommodate fastening means. It is preferred that a pair of the openings on a common axis and relative to a vertical central plane of the cover are arranged opposite one another. In particular, it can be the case that the opposite openings form pivot holes which are designed for the pivotable attachment of an outer visor.
- This outer visor can be a conventional visor of the protective helmet, which is intended to offer mechanical protection. Attaching the readilyvi siers to the cover also ensures that the visor on the inside to Outer visor is arranged so that it can also be protected by the outer visor.
- a preferred embodiment of the visor mechanism is characterized in that the cover has at least one locking hole for locking the contemplatvi siers. This makes it easier to hold the outer visor in the desired position. It is preferred that the cover has at least two substantially opposing locking holes. It is further preferred that the locking holes are each arranged adjacent to a rotary hole. The cover can also have more than two locking holes. The outer visor can be held in a desired position through these locking holes. Further details on the mode of operation are described below in connection with the outer visor. In particular, it can be the case that in each case a pivot hole with the adjacent locking hole or the adjacent locking holes is arranged on an essentially flat section of the cover. This makes it easier to arrange the locking holes in the area swiveled by the outer visor.
- a respective pin element of the visor mechanism is arranged in the at least one locking hole in such a way that the respective pin element protrudes at least partially from the at least one locking hole.
- Such a pin element can also be used to lock the outer visor.
- the visor mechanism is provided separately and can therefore be mounted on a protective helmet.
- the visor mechanism can be retrofitted to a protective helmet that was not intended for such an assembly from the start. But it can also be that the visor mechanism is a fixed and original component of a protective helmet.
- the protective helmet according to the proposal which can in particular be a protective helmet for emergency services, is characterized in that the protective helmet has an outer shell for distributing impact forces and a visor mechanism according to the proposal attached to the outer shell. It is preferred that the protective helmet has fastening means for fastening the cover to the outer shell.
- a preferred embodiment of the protective helmet according to the proposal is characterized in that the protective helmet has an outer visor for mechanical face protection, which outer visor is pivotably attached to the outer shell. It is further preferred that the outer visor is attached to the outer shell by means of the pivot holes. This fastening can take place in particular by means of a passage of the outer visor or a fastening element through the pivot holes.
- the outer visor is arranged such that the outer visor can cover the visor. It is further preferred that the outer shell has bores aligned with the rotary holes for fastening the visor mechanism and / or the outer visor to the outer shell.
- the outer visor has a sealing element for sealing between the outer visor and the visor. It is preferred that the outer visor has an outer visor, on which the upper edge the sealing element is arranged. In particular, it can be the case that the sealing element extends over a substantial part of the upper edge of the outer visor. Such a sealing element prevents precipitation or other liquids from getting past the outer visor to the visor.
- the outer visor has at least one visor locking plate, each with at least one locking recess.
- Each Rastver recess can correspond to a locking position of the outer visor on the outer shell.
- the at least one latching recess can be designed to accommodate the corresponding pin element in a latching position of the outer visor.
- the locking depressions can also be continuous locking holes.
- the at least one visor locking plate is attached to an upper edge of the outer visor on the outer visor. But it is also conceivable that the outer visor has at least one visor locking plate with at least one locking projection for the respective engagement in the min least one locking hole.
- the visor is independent of a swivel position of the outer visor can be moved.
- the locking arrangement when the locking arrangement is in a released state, the visor can be displaced regardless of how the outer visor is pivoted.
- the locking device blocks the shifting of the visor regardless of the pivoting state in which the outer visor is.
- features and properties of the protective helmet according to the proposal correspond to preferred embodiments, features and properties of the visor mechanism according to the proposal and vice versa.
- FIG. 1 shows a perspective exploded view of an embodiment of a proposed visor mechanism
- Fig. 4a, b each show a lower view of the proposed Visiermecha technology of Fig. 1 with different positions of the visor and the Vi sierverstellers,
- 5a, b show a side view and a top view of a protective helmet according to the proposal with the visor mechanism according to the proposal of FIG. 1 with the position of the visor and the visor adjuster as in FIG. 4a
- FIGS. 4b and 7a, b each show a side view of the proposed protective helmet of FIG. 4 with an outer visor in different positions.
- the proposed visor mechanism shown in FIG. 1 is intended for attachment to a protective helmet for emergency services. It can also be attached to such a protective helmet at a later date.
- the visor mechanism comprises a visor 1, which here consists of a disc 2.
- the pane 2 is semi-transparent and, as a laser protection pane, has laser protection properties.
- the visor mechanism is attached to an outer shell 4 of the protective helmet as shown in FIGS. 5a, b and 6a, b.
- the visor 1 can be displaced with respect to this outer shell 4, the different positions of the visor 1 resulting from this displacement from FIGS. 5a, b and 6a, b.
- the extended position - the visor 1 and especially the pane 2 cover a front area of the protective helmet.
- the visor mechanism also has a visor adjuster 5, which is coupled to the visor 1 via a locking arrangement 6, and a cover 7, which is arranged in a stationary manner on the outer shell 4, so that a displacement of the visor 1 with respect to the outer shell 4 is equivalent to a displacement of the visor 1 opposite the cover 7 is. Therefore, the visor 1 is covered in the retracted position according to FIGS. 5a, b of the cover 7 and is consequently not seen in FIGS. 5a, b.
- the cover 7 has a front cover part 7a and a rear cover part 7b.
- the visor adjuster 5 can be displaced along an outer surface 8 of the cover 7 here, which leads to a displacement of the visor 1 along an inner surface of the cover 7.
- This displacement of the visor adjuster 5 takes place essentially along a central axis 24 shown in FIGS. 4a, b, which extends in a longitudinal direction of the protective helmet. Since the outer shell 4 is curved, the visor adjustment ler 5 also essentially a circular path, which can be seen in particular from FIGS. 5a and 6a.
- the locking arrangement 6 consists of a slide guide 9 and a sliding element 10 received by the slide guide 9, which in turn consists of a carrier part 3 to which the visor 1 is attached, a locking plate 11 and a cross member 12.
- the locking plate 11 in turn has a spring arrangement 13.
- the locking plate 11 is positively coupled to the carrier part 3.
- a projection 3 a of the carrier part 3 is guided through an opening 11 a formed by the locking plate 11. This relationship is shown in FIG.
- the visor adjuster 5 is coupled to the cross member 12 of the displacement element 10 and thus to the locking arrangement 6 as a whole.
- the cover 7 On its side facing the outer shell 4, the cover 7 has blocking structures 15, which are designed here as essentially semi-cylindrical recesses which extend along the displacement path of the displacement element 10.
- the visor adjuster 5 By actuating the visor adjuster 5 in a direction along the outer shell 4 - which actuation is referred to here as a sliding actuation in contrast to the release actuation - the visor 1 can now be extended or retracted, but only as long as the release actuation is maintained.
- the blocking element 16 comes back into engagement with a blocking structure 15 due to the bias of the spring arrangement 13, so that further displacement of the visor 1 is prevented.
- the visor mechanism also has slideways 14a, b which are connected to the cover 7 and which serve to guide the visor 1.
- the Trä gteil 3 has formed as projections carrier mounting devices 23 which snap into corresponding disc mounting devices 22 of the disc 2, which are designed as mounting openings.
- the cover 7 of the embodiment shown in the drawing has a total of three openings 17 through which the cover 7 can be attached to the outer shell 4. Specifically, these openings 17 are aligned with corresponding bores in the outer shell 4, which are not visible here, so that corresponding fastening means can be guided both through the openings 17 and through the bores in the outer shell 4.
- a pair of the openings 17 are arranged on a common axis opposite one another in the temple area of the protective helmet, while the third opening 17 is placed in a central rear area of the cover 7 - especially in the rear cover part 7b.
- This arrangement of the pair of openings 17 also makes it possible, as shown in FIGS. 7 a, b, to fasten an outer visor 18 pivotably on the outer shell 4 and the cover 7.
- the opposite openings 17 form pivot holes 17a or can be designated as a pair of pivot holes 17a.
- the outer visor 18 has an outer visor disc 21 and a sealing element 20 on the upper edge of the outer visor disc 21.
- a latching hole 19 of the cover 7 is arranged adjacent to a rotary hole 17a.
- These locking holes 19 serve to hold the outer visor 18 in particular in the open position as shown of Fig. 7b.
- Stif tiata not shown in the drawing, are provided for this purpose, which are arranged in the locking holes 19 and partially protrude from the locking holes 19.
- the outer visor 18 has visor locking plates 24 with two locking depressions 25 here, the locking depressions 25 receiving the pin elements for locking the outer visor 18 in different locking positions.
- 7a shows the closed position of the outer visor 18. In this closed position, the visor 1 and in particular the disc 2 are covered by the outer visor 18 and thus protected.
