Description

[0001] The invention relates to a visor mechanism for a protective helmet with the features of the preamble of claim 1 and to a protective helmet with such a visor mechanism.

[0002] Protective helmets, especially those used by police or other emergency services, primarily serve to protect the wearer from mechanical injuries. In addition to the standard outer shell, they typically feature a visor with a transparent lens, which can be flipped down to protect the face, particularly from blows to the face or thrown objects.

[0003] Due to technological advances in recent years, laser pointers have entered the market that, despite their small size, can achieve high beam power. Legal regulations limiting the power of available laser pointers have proven easily circumvented. Because of their dangerous glare, high-powered laser pointers in particular pose a new hazard to police and other emergency services, and countermeasures against this have rarely been considered in standard police equipment. A suitable means of protection against laser beams is the use of lenses with special optical properties, which can be placed in front of the eyes as visors.

[0004] It is known from the prior art to either integrate such visors directly into a protective helmet or to offer them as a retrofittable device for protective helmets. It is advantageous to position such a laser protection visor—similar to a conventional visor against mechanical hazards—optionally and therefore only when needed, since the danger posed by laser pointers exists only in certain situations, and the required tint of the protective visor could impair vision too much in other situations. It is also advantageous to provide a separate visor for laser protection than the main visor for mechanical protection. While the main visor must cover the entire face, laser protection is only required for the eyes.When using only the laser protection, the mouth area can remain free, which in turn facilitates communication for the wearer of the protective helmet and reduces the risk of the laser protection lens fogging up.

[0005] To selectively move the laser guard between an extended protective position and a retracted position in which the guard does not cover the eye area, a sliding mechanism is known. This sliding mechanism should, on the one hand, allow the laser guard to be reliably and quickly moved into the desired position and, on the other hand, prevent it from being unintentionally moved. Such an unintentional movement from the extended to the retracted position would obviously be dangerous, but even unintentional extension can have negative consequences.

[0006] Prior art EP 2 689 680 A2 discloses a recreational sports helmet. The recreational sports helmet comprises a helmet body, goggles, a sliding guide unit, and a handle. The helmet body has a sliding slot in a front section. Ventilation holes are formed in a circumferential surface of the helmet body. The goggles are positioned in the sliding slot and are pulled out of or retracted into the helmet body by sliding. The sliding guide unit is provided in the sliding slot to support and guide the goggles. The handle is detachably connected to the goggles so that the goggles can slide along the sliding slot.

[0007] Prior art EP 1 797 783 A1 discloses a device for opening and closing a helmet's sun visor. The device comprises a helmet body having an opening section for the face at the front and a pair of hinge axes projecting on both the left and right sides; a sun visor with a visor section arranged on the side of the opening section of the helmet body; extension sections extending to the left and right sides of the visor section; and hinge slots formed at the ends of the extension sections. It also includes an opening and closing mechanism with a slider connected to the upper center of the visor section of the sun visor, a guide rail attached to the top of the helmet body, and a guide holder mounted longitudinally at the top center of the helmet body.

[0008] DE 1 947 919, a prior art patent, discloses a coupling with a toothed rail mounted on a first component and a toothed coupling shoe mounted on a second component, wherein the two components are movable relative to each other, characterized in that the coupling shoe is movably mounted to be movable back and forth between an engaged position, in which the teeth of the coupling shoe are in engagement with the teeth of the rail, and a disengaged position, in which the teeth are not in engagement, and in that cam elements, which can be actuated by a handle, are connected in working relation to the coupling shoe and are able to move it back and forth between two positions.

[0009] The prior art document DE 2 041 485, from which the present invention is considered closest, discloses the preamble of claim 1. It discloses a safety helmet characterized by a shell for receiving the head of a wearer, a first and a second visor, elements attached to the shell, and side parts of both visors for moving each visor along a curved path between a visor position in front of the wearer's eyes and a retracted position above the front part of the shell, wherein the first visor is arranged outside the second visor, and stops carried by an upper part of the second visor and projecting outwards from it above an upper part of the first visor, so that the aforementioned upper part of the first visor rests against it to prevent a downward movement of the second visor below the first visor.

[0010] Based on this prior art, the object of the invention is therefore to further develop and improve a visor mechanism for a protective helmet known from the prior art in such a way that the visor or laser protection can be brought into the protective position quickly and reliably and is unlikely to be unintentionally moved from this position.

[0011] This problem is solved for a visor mechanism with the features of the preamble of claim 1 by the features of the characterizing part of claim 1. With respect to a protective helmet, they are solved by a protective helmet with the features of claim 14.

[0012] Essential to the invention is the realization that the structure used for the movement can also be used to lock the visor or laser guard in place. In this way, only one hand is required to move the visor or laser guard into the desired position and simultaneously ensure that it remains in that position.

[0013] The visor mechanism according to the invention is for a protective helmet, which can in particular be a protective helmet for emergency personnel. The proposed visor mechanism comprises a visor which is slidably mounted relative to an outer shell of the protective helmet to cover a front area of ​​the helmet, and a visor adjuster which is coupled to the visor in such a way that the visor can be moved by sliding the visor adjuster. A front area of ​​the protective helmet is understood to be the open front area, which corresponds to the face area and in particular the eye area of ​​a wearer of the protective helmet. The sliding actuation can be of virtually any type of actuation of the visor adjuster.

[0014] The sight mechanism according to the invention is characterized in that the sight mechanism has a locking arrangement coupled to the sight and the sight adjuster, which locking arrangement, in a locked state, blocks any movement of the sight and, in a released state, allows any movement of the sight. The sight mechanism according to the invention is further characterized in that the locking arrangement can be brought into the released state by actuating the sight adjuster.

[0015] The locking mechanism can therefore alternately assume a locked state and a released state. Besides the locked and released states, there can also be other states that the locking mechanism can assume. The release actuation can, in principle, be any type of actuation of the sight adjuster. Blocking the movement of the sight also blocks the movement of the sight adjuster.

[0016] Preferably, the locking mechanism provides a force transmission chain from the sight adjuster to the sight. This differs from a mechanism in which, for example, actuating the sight adjuster unlocks a pre-tensioned spring, which then moves the sight.

[0017] According to the invention, the visor mechanism has a cover for fixed mounting on the outer shell. In particular, the visor may be slidably mounted relative to the cover. Likewise, the visor adjuster may be slidably mounted relative to the cover.

[0018] According to the invention, the visor is arranged below the cover and the visor adjuster is arranged on the cover. The terms "below" and "above" can refer to the outer shell of the protective helmet. Consequently, this preferred embodiment corresponds to an arrangement of the visor between the cover and the outer shell and an arrangement of the visor adjuster such that the cover is located 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 position are achieved.

[0019] Preferably, the visor and / or the visor adjuster are displaced substantially along a surface of the cover. This means, in particular, that the displacement need not follow a straight path, but can also describe a curve. Specifically, the displacement of the visor adjuster, and alternatively or additionally the displacement of the visor, may essentially follow a circular path or other curve.

[0020] According to a preferred embodiment of the sight mechanism, the locking arrangement is designed to spring back into the locked position after the release actuation has ended. In other words, the locking arrangement is "pre-tensioned" to the locked position. This ensures reliable locking of the sight whenever the release actuation is not being performed. According to the invention, the locking arrangement includes a spring assembly for pre-tensioning the locking arrangement to the locked position. In other words, the spring assembly is designed to bring the locking arrangement into the locked position in the absence of any opposing force – for example, from the release actuation.

[0021] According to the invention, the locking arrangement comprises a slide guide fixed to the outer shell and a sliding element coupled to the sight adjuster and received by the slide guide. In particular, the sliding element is a movable element. The sliding element can, in particular, be coupled to the sight adjuster in such a way that the sliding element is moved along with the sight adjuster during a movement.

[0022] It is further preferred that the sliding element includes a locking element which, in the locked position, engages positively in the cover to block the movement of the visor. In particular, the locking element may be specifically incorporated into the slide guide as part of the sliding element. The locking element is preferably a substantially semi-cylindrical projection.

[0023] A preferred embodiment of the visor mechanism is characterized in that the cover has a plurality of blocking structures, each designed to receive the blocking element. Accordingly, the plurality of blocking structures are preferably essentially semi-cylindrical recesses. This design ensures that the blocking element regularly slides into one of the two blocking structures, even when in an intermediate position between them. Furthermore, the blocking structures may be arranged along a displacement path of the displacement element. It is preferred that the blocking structures are arranged essentially one behind the other, adjacent to each other. In this way, there are no gaps between the individual blocking structures. It is further preferred that each blocking structure defines a different displacement position of the displacement element.Preferably, the blocking structures are arranged on one side of the cover facing the outer shell.

[0024] Another preferred embodiment of the sight mechanism is characterized in that the spring arrangement is configured to pre-tension the locking element in the direction of the locking structures. It is also preferred that the sliding element is configured to release the locking element from the locking structures upon activation of the sight adjuster.

[0025] According to the invention, the sliding element has a cross member which is arranged between the outer shell and the spring assembly and which is configured to exert a tensile force on the spring assembly in the direction of the outer shell upon release actuation. This tensile force on the spring assembly can also be described as being directed opposite to the direction towards the locking structures.

[0026] A preferred embodiment of the visor mechanism is characterized in that the release actuation is a pressure actuation of the visor adjuster essentially perpendicular to the outer shell. This type of actuation ensures that the user, and thus the wearer of the protective helmet, can apply sufficient force to release the visor from the locked position. In contrast, for the sliding actuation, it is preferred that the sliding actuation is an actuation of the visor adjuster essentially along the outer shell. These different actuation directions allow the two types of actuation to be controlled and optionally performed separately or together.

[0027] In principle, the visor can be a single, molded part. According to a further preferred embodiment of the visor mechanism, the visor has a disc that is at least semi-transparent. In this case, the disc represents the part of the visor that can be moved in front of the eyes of the wearer of the protective helmet. Preferably, the disc is attached to a support part of the sliding element by a positive fit.

[0028] A preferred embodiment of the visor mechanism is characterized in that the visor includes a laser safety lens for eye protection against laser beams. It is preferred that the lens is the laser safety lens.

[0029] Another preferred embodiment of the visor mechanism is characterized in that the disc has at least one disc mounting device and the carrier part has a carrier mounting device corresponding to the disc mounting device, wherein the disc mounting device and the carrier mounting device are configured to create a positive-locking engagement with each other. In particular, the disc mounting device and the carrier mounting device may be configured to create a snap-fit ​​connection with each other. The carrier mounting device may have a mounting opening and the disc mounting device a projection for snapping into the mounting opening. Alternatively, the disc mounting device may have a mounting opening and the carrier mounting device a projection for snapping into the mounting opening.The variants just described make it particularly easy to create a connection between the disc and the support part.

[0030] In principle, the visor adjuster can be operated to move the visor in any direction. However, according to a preferred embodiment of the visor mechanism, the visor adjuster, particularly when the cover is fixed on the outer shell, is essentially displaceable along a central axis in the longitudinal direction of the helmet. It is further preferred that the slider guide is arranged essentially around a vertex of the outer shell. This ensures good manual access to the visor adjuster, even when the wearer of the helmet is wearing gloves.

[0031] A preferred embodiment of the visor mechanism is characterized in that the visor can be moved by direct actuation of the visor. Such direct actuation of the visor thus involves manual intervention by the wearer of the protective helmet. Preferably, the visor can be moved by direct actuation of the visor when the locking mechanism is in the release state. Preferably, the locking mechanism blocks the movement of the visor by direct actuation of the visor when the locking mechanism is in the locked state.

[0032] According to a further preferred embodiment of the visor mechanism, the cover has a plurality of openings for attaching it to the outer shell. These openings can, in particular, serve to accommodate fastening elements. Preferably, a pair of openings is arranged opposite each other on a common axis and with respect to a vertical central plane of the cover. In particular, the opposing openings can form pivot holes designed for the pivotable attachment of an external visor. This external visor can be a conventional visor of a protective helmet, intended to provide mechanical protection. Attaching the external visor to the cover also ensures that the visor is positioned on the inside of the external visor, so that it can also be protected by the external visor.

[0033] A preferred embodiment of the sight mechanism is characterized in that the cover has at least one detent hole for locking the outer sight. This makes it easier to hold the outer sight in the desired position. It is preferred that the cover has at least two detent holes that are substantially opposite each other. It is further preferred that the detent holes are each arranged adjacent to a pivot hole. The cover may also have more than two detent holes. These detent holes allow the outer sight to be held in a desired position. Further details of the operation are described below in connection with the outer sight. In particular, each pivot hole may be arranged with the adjacent detent hole or holes on a substantially flat section of the cover.This facilitates the placement of the locking holes in the area covered by the external sight when pivoting. It is further preferred that each pin element of the sight mechanism is arranged in the at least one locking hole such that the respective pin element protrudes at least partially from the at least one locking hole. Such a pin element can also serve to lock the external sight in place.

[0034] Preferably, the visor mechanism is provided separately and can therefore be mounted on a protective helmet. In particular, it may be possible to retrofit the visor mechanism to a protective helmet that was not originally designed for such mounting. However, it is also possible that the visor mechanism is an integral and original component of a protective helmet.

[0035] The proposed protective helmet, which may in particular be a protective helmet for emergency personnel, is characterized in that the helmet has an outer shell for distributing impact forces and a proposed visor mechanism attached to the outer shell. Preferably, the helmet has fastening means for attaching the cover to the outer shell.

[0036] A preferred embodiment of the proposed protective helmet is characterized in that the helmet has an external visor for mechanical face protection, which is pivotably attached to the outer shell. It is further preferred that the external visor is attached to the outer shell by means of the pivot holes. This attachment can be effected, in particular, by passing the external visor or a fastening element through the pivot holes. It is especially preferred that the external visor is arranged such that it can cover the face shield. It is further preferred that the outer shell has bores aligned with the pivot holes for attaching the visor mechanism and / or the external visor to the outer shell.

[0037] According to a preferred embodiment of the proposed protective helmet, the outer visor has a sealing element for sealing between the outer visor and the inner visor. It is preferred that the outer visor has an outer visor disc, on the upper edge of which the sealing element is arranged. Specifically, the sealing element may extend over a substantial portion of the upper edge of the outer visor disc. Such a sealing element prevents precipitation or other liquids from bypassing the outer visor and reaching the inner visor.

[0038] According to a further preferred embodiment of the proposed protective helmet, the outer visor has at least one visor locking plate, each with at least one locking recess. Each locking recess can correspond to a locking position of the outer visor on the outer shell.

[0039] In particular, the at least one detent recess can be configured to receive the corresponding pin element in a detent position of the outer sight. The detent recesses can also be through-holes. It is further preferred that the at least one sight detent plate is attached to the outer sight disc at an upper edge. However, it is also conceivable that the outer sight has at least one sight detent plate with at least one detent projection for engaging with the at least one detent hole.

[0040] Another preferred embodiment of the proposed protective helmet is characterized in that the visor is movable independently of the pivot state of the outer visor. In other words, the visor can be moved in a release state of the locking arrangement regardless of how the outer visor is pivoted. Conversely, in the locked state, the locking arrangement blocks the movement of the visor regardless of the pivot state of the outer visor.

[0041] Preferred embodiments, features and properties of the proposed protective helmet correspond to preferred embodiments, features and properties of the proposed visor mechanism and vice versa.

[0042] Further advantageous and preferred embodiments will become apparent from the following description with reference to the figures. The drawing, which depicts only one exemplary embodiment, shows... Fig. 1 a perspective exploded view of an embodiment of a proposed sighting mechanism, Fig. 2 a first detail view of the proposed sighting mechanism of the Fig. 1 , Fig. 3 a second detailed view of the proposed sighting mechanism of the Fig. 1 , Fig. 4a, b each a lower view of the proposed sighting mechanism of the Fig. 1 with different positions of the visor and the visor adjuster, Fig. 5a, side view and top view of a proposed protective helmet with the proposed visor mechanism of the Fig. 1 with the position of the visor and the visor adjuster as shown in the Fig. 4a Fig. 6a, side view and top view of a proposed protective helmet with the proposed visor mechanism of the Fig. 1 with the position of the visor and the visor adjuster as shown in the Fig. 4b and Fig. 7a, each a side view of the proposed protective helmet of the Fig. 4 with an external visor in different positions.

[0043] The one in Fig. 1 The proposed visor mechanism shown is designed for attachment to a protective helmet for emergency personnel. It can also be retrofitted to such a helmet. The visor mechanism comprises a visor 1, which in this case consists of a disc 2. The disc 2 is semi-transparent and, as a laser protection disc, exhibits laser protection properties.

[0044] The sighting mechanism is described in the illustration of Fig. 5a, b and 6a, b attached to an outer shell 4 of the protective helmet. The visor 1 can be moved relative to this outer shell 4, whereby the different positions of the visor 1 are determined by this movement. Fig. 5a, b and 6a, b emerge. In the position corresponding to the Fig. 6a, b - in the extended position - the visor 1 and especially the lens 2 cover a front area of ​​the protective helmet.

[0045] The sight mechanism further comprises a sight adjuster 5 coupled to the sight 1 via a locking arrangement 6 and a cover 7 which is fixedly arranged on the outer shell 4, such that a displacement of the sight 1 relative to the outer shell 4 is equivalent to a displacement of the sight 1 relative to the cover 7. Therefore, the sight 1 is in the retracted position according to the Fig. 5a, b covered by cover 7 and is therefore in the Fig. 5a, b not visible. In the present embodiment, the cover 7 has a front cover part 7a and a rear cover part 7b.

[0046] The visor adjuster 5 can be moved along an outer surface 8 of the cover 7, which leads to a movement of the visor 1 along an inner surface of the cover 7.

[0047] This displacement of the visor adjuster 5 essentially occurs along a path in the Fig. 4a, b The central axis 24 shown extends in a longitudinal direction of the protective helmet. Since the outer shell 4 is curved, the visor adjuster 5 also essentially follows a circular path, which is particularly evident from the Fig. 5a and 6a can be detected.

[0048] The locking arrangement 6 consists of a slide guide 9 and a sliding element 10 received by the slide guide 9. The sliding element 10 itself comprises a carrier part 3, to which the sight 1 is attached, a locking plate 11, and a cross member 12. The locking plate 11, in turn, has a spring assembly 13. The locking plate 11 is positively coupled to the carrier part 3. Specifically, a projection 3a of the carrier part 3 is guided through an opening 11a formed by the locking plate 11. This relationship is shown in the Fig. 2 shown.

[0049] The visor adjuster 5 is coupled to the cross member 12 of the sliding element 10 and thus to the locking arrangement 6 as a whole.

[0050] The cover 7 has blocking structures 15 on its side facing the outer shell 4, which are designed here as essentially semi-cylindrical recesses extending along the displacement path of the displacement element 10.

[0051] The engagement of the spring assembly 13 with the slide guide 9, which is in the Fig. 3 As can be seen, this causes the support part 3 to be pushed away from the slide guide 9 towards the cover 7. Consequently, the locking element 16 is also pushed towards the cover 7. Therefore, without any further external influence, the locking arrangement 6 assumes a locking state in which the locking element 16 engages positively in the locking structure 15 of the cover 7 that corresponds to the current position of the sight adjuster 5 and thus of the cross member 12. The locking effect of this engagement fixes the sight 1 in its current position.

[0052] Only when the wearer of the protective helmet releases it by pressing the visor adjuster 5 towards the outer shell 4 does the locking mechanism 6 assume the released state. The pressure on the visor adjuster 5 also moves the support part 3 towards the outer shell 4, contrary to the preload of the spring assembly 13.

[0053] In this way, the locking element 16 disengages from the locking structures 15 of the cover 7. The locking arrangement 6 has thus entered the release state. By actuating the visor adjuster 5 in one direction along the outer shell 4 – an actuation referred to here as 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. When the release actuation is terminated, the locking element 16, due to the preload of the spring arrangement 13, engages a locking structure 15 again, thus preventing any further movement of the visor 1.

[0054] The sight mechanism further comprises sliding tracks 14a, b, which are connected to the cover 7 and which serve to guide the sight 1. The support part 3 has support mounting devices 23 designed as projections, which engage in corresponding disc mounting devices 22 of the disc 2, which are designed as mounting openings.

[0055] 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 align with corresponding bores in the outer shell 4 (not visible here), so that appropriate fastening elements can be guided through both the openings 17 and the bores in the outer shell 4. One pair of the openings 17 is arranged opposite each other on a common axis in the temple area of ​​the helmet, while the third opening 17 is located in a central rear area of ​​the cover 7 – specifically in the rear cover section 7b. This arrangement of the pair of openings 17 also allows, as shown in the Fig. 7a Figure b shows an external visor 18 pivotally attached to the outer shell 4 and the cover 7. Accordingly, the opposing openings 17 form pivot holes 17a or can be referred to as a pair of pivot holes 17a. The external visor 18 has an external visor disc 21 and a sealing element 20 at the upper edge of the external visor disc 21.

[0056] As in the Fig. 1 As can be seen, a locking hole 19 of the cover 7 is arranged adjacent to each rotating hole 17a. These locking holes 19 serve to secure the outer visor 18, particularly in the open position as shown in the illustration. Fig. 7b to lock into place. Specifically, pin elements (not shown in the drawing) are provided for this purpose. These pin elements are arranged in the locking holes 19 and partially protrude from them. Accordingly, the outer sight 18 has sight locking plates 24, each with two locking recesses 25. The locking recesses 25, in different locking positions, accommodate the pin elements for locking the outer sight 18. Fig. 7a Figure 1 shows the closed position of the outer visor 18. In this closed position, the visor 1 and especially the lens 2 are covered and thus protected by the outer visor 18.
