DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS
[0033] It is worth noting here that the same parts have been given the same reference numerals or same component designations in the embodiments described differently, yet the disclosures contained throughout the entire description can be applied analogously to the same parts with the same reference numerals or the same component designations. The indications of position selected in the description, such as above, below, on the side etc. refer to the figure directly described and shown, and these indications of position can be applied in the same way to the new position should the position change.
[0034]
[0035] The sport helmet assembly 1 comprises at least one helmet 2 with a helmet shell 3 and a visor 4 that can be pivoted and also adjusted in a translational manner relative to the helmet shell 3. The helmet 2 can further comprise fastening means (not shown), such as a chin strap for holding and securing the helmet 2 to the head of a user (not shown), and/or lateral tabs for protecting the ears of the user from the cold. A lining is usually provided, in particular a padding is arranged or received, for the head of the user in a receiving space 5 formed by the helmet shell 3. To adjust width and correspondingly adjust to the head circumference of the user, a head width adjustment device (
[0036] The helmet 2 with its helmet shell 3 is not configured as a full-face or integral helmet, but rather in the manner of a hollow dome or in the manner of a half-shell helmet, wherein the helmet shell 3 extends laterally, namely on the left and right sides forming at least one temple region 6, and at least also covers the latter in sections for the user. The helmet shell 3 and/or the padding can also extend over an ear area or form the latter on both sides. The helmet 2 or its helmet shell 3 further defines a helmet shell upper side 7, a front side 8 and a rear head side 9 in the normal position of use and when the user is standing upright. For a better and simpler definition of indications of position and arrangements with respect to one another, a central plane 10 is defined. In the aforementioned position of use, the central plane 10 forms a vertical plane, which is arranged to extend centrally between the two temple regions 6. The central plane 10 further extends from the front side 8 towards the rear head side 9 of the helmet 2 or its helmet shell 3.
[0037] On its front side 8, the helmet shell 3 with a helmet shell edge 11 defines a facial clearance 12, which extends over a forehead region up to the two temple regions 6. The facial clearance 12 serves to release and not cover at least a sub-portion of the forehead of the user, the eye area, and preferably also the nose of the user. When in the protective position or closed position, the visor 4 (
[0038] The visor 4 comprises a substantially arcuately curved disk made of a transparent or sheer, in particular translucent, plastic.
[0039] As already stated above, the visor 4 is mounted on the helmet shell 3 in both an articulated or pivotable and displaceable manner. This mounting is carried out by means of the two end portions, namely a left end portion 13 and a right end portion 14 of the visor 4. A bearing device 15 is provided for this purpose, which itself comprises a left bearing arrangement 16 and a right bearing arrangement 17. Each of the bearing arrangements 16, 17 is also arranged or formed in the respective temple region 6 of the helmet 2. These are mostly independent components or component parts. The left bearing assembly 16 defines or forms a left pivot axis 18 and the right bearing assembly 17 defines or forms a right pivot axis 19 for the visor 4. mounted thereon. The pivot axis 18, 19 can be formed by a physical axis or can represent only an imagined axis. The left pivot axis 18 and the right pivot axis 19 are preferably aligned or at least approximately aligned.
[0040] The visor 4 comprises or forms an upper visor edge region 20 and a lower visor edge region 21. The two visor edge regions 20, 21 extend between the two end portions 13, 14 of the visor 4. The visor 4 has a curved or arcuate longitudinal extension over its circumferential extension between the two end portions 13, 14 or the bearing arrangements 16, 17. The lower visor edge region 21 can be made to face the nose or chin of the user, in particular such as the former is closer to these body portions than the upper visor edge region 20.
[0041] As a result of the pivotable and also relatively displaceable mounting of the visor 4 on the helmet shell 3 of the helmet 2, the visor 4 can be pivoted, as required, about the pivot axes 18,19 between a closed position (protective position) substantially or completely covering the facial clearance 12, and an open position (release position) substantially or completely releasing the facial clearance 12 and vice versa. The two positions (closed position and open position) each define maximum positions, between which intermediate positions of the visor 4 are also possible. In the covering closed position (
[0042] If the visor 4 is in its closed position, a protrusion 22 on the helmet shell 3 or on the side of the helmet shell 3 itself can project beyond the upper visor edge region 20 of the former, at least in the region of the central plane 10, as can best be seen in
[0043] A maximum available translational travel range of the visor 4, in particular a maximum available displacement length 24 of the visor 4 in the direction of the rear head side 9 can be limited by a rear limiting stop 25, said rear limiting stop 25 can be formed or arranged on the left and right bearing arrangement 16, 17 (
[0044] In the lower visor edge region 21, a sealing element 27 is provided on the visor 4 (
[0045] As already explained above, the left bearing arrangement 16 and the right bearing arrangement 17 are each configured in the manner of sliding joints. Correspondingly, the left bearing arrangement 16 has a left sliding guide 28 in addition to the left pivot axis 18 and the right bearing arrangement 17 has a right sliding guide 29 in addition to the right pivot axis 19 such that the visor 4 can be pivoted and displaced relative to the helmet shell 3 from the closed position into an open positionand vice versaby means of the bearing arrangements 16,17 during a manually executed displacement movement.
[0046] The at least one sealing element 27 in the lower visor edge region 21 can be configured in a single-part or multi-part manner. In particular, this can be formed from a homogeneous foam plastic. The sealing element 27 is preferably formed from several soft-elastic or elastically resilient materials, which can be constructed in a sandwich-like manner or can be arranged overlying one another. A thickness 30 of the single-part or multi-part sealing element 27 is measured from the inner side 23 of the visor 4 in the direction of the rear head side 9.
[0047] An available displacement length 24 of the left and right sliding guide 28,29 and a thickness 30 of the sealing element 27 measured from the inner side 23 of the visor 4 in the direction of a rear head side 9 of the helmet 2 are dimensioned such that the sealing element 27 can be pressed against face portions below the eyes of the user in the closed position of the visor 4 by means of the left and right sliding guide 28, 29. In particular, the linear or slightly arcuate sliding guides 28, 29 for providing the respective displacement length 24 of the visor 4 are dimensioned such that the sealing element 27 can press against a large number or at least a majority of head sizes or face shapes of users or can be pressed against the face portions below the eye region and can thus ensure good sealing of the eye region against drafts or cold air. In the closed position of the visor 4 (
[0048] In order to achieve a continuous or controlled pressing force of the visor 4 or its sealing element 27 against the face of a user, it is expedient for at least one of the two sliding guides 28 or 29, preferably both the left and the right sliding guides 28 and 29, to each be assigned at least one spring element 31, 32. The at least one spring element 31, 32 acts in such a way that the visor 4 is continuously pushed in the direction of an end position 33
[0049] The spring force of the at least one spring element 31, 32 can be dimensioned such that the visor 4 can be displaced into distance positions 35 comparatively further away from the rear head side 9 by the user by gripping the visor 4, in particular by grasping the visor 4 in each of the two temple regions 6, as is shown by way of example with dashed lines in
[0050] As can be seen in
[0051]
[0052] In
[0053]
[0054] Furthermore, the left and/or right bearing arrangement 16, 17 can comprise at least one latching element 36 (
[0055]
[0056] The left sliding guide 28 comprises a left linear guide element 37 and the right sliding guide 29 comprises a right linear guide element 38, said linear guide elements 37, 38 are mounted on the visor 4 and each form wedge-shaped projections 39, 40 with relative to the inner side 23 of the visor 4. These wedge-shaped projections 39, 40 are displaceably received in corresponding, wedge-shaped recesses 41, 42 in each of the two temple regions 6 of the helmet shell 3. The helmet shell 3 is illustrated in this case including an inner lining or padding and has a sufficient thickness to be able to form the recesses 41, 42 on the outside of the helmet shell 3.
[0057] The wedge-shaped projections 39, 40 on the inner side 23 of the visor 4 can form base surfaces 43, 44 that are adjacent or face one another, said base surfaces 43, 44 extending parallel or largely parallel to one another. These base surfaces 43, 44 extending as parallel to one another as possible on the visor inner side 23 are supported in a slidable manner on base surfaces 45, 46 that extend parallel or largely parallel to one another, in each of the two recesses 41, 42 in the helmet shell 3. Accordingly, the visor 4 can be slidably displaced with its base surfaces 43, 44 in the direction of the front side 9 and also in the direction of the rear head side 9 relative to the helmet shell 3.
[0058] It is expedient for the linear guide elements 37, 38 configured in a frame-like manner, for example, to be inserted into and held in a respective opening 47, 48 in the lateral end portions 13, 14 of the visor 4. This holder can be expediently implemented as a positively acting latching connection between the linear guide elements 37, 38 and the visor 4 (shown by way of example).
[0059] As can further be derived from
[0060] In order to achieve a robust and smooth-running sliding and pivoting bearing (sliding joint) that is wear free in the long term for the visor 4, it can be provided that the left and right screw 49, 50 each pass through a left and right sliding block 51, 52 and thereby support these sliding blocks 51, 52 rotatably about their screw axes. In addition, the left and right linear guide element 37, 38 on the visor 4 are relatively displaceable relative to the left and right sliding block 51, 52. The screw axes of the left and right screw 49, 50 define the left and right pivot axis 18, 19, which are fixed in position on the helmet shell 3.
[0061] The sliding blocks 51, 52 and the screw heads of the screws 49, 50 are received in the wedge-shaped projections 39, 40 formed on the inner side 23 of the visor 4, which form defined receiving spaces tapered in a wedge shape. The same applies to the spring elements 31, 32 shown in
[0062] As can also be seen from the embodiment according to
[0063] The embodiments show possible design variants, however it is noted at this point that the invention is not restricted to the design variants of the same specifically shown, rather various combinations between the individual design variants are possible and these possible variants can be developed using the knowledge of the person skilled in the art working in this field based on the teachings of technical practice offered by the current invention.
[0064] The scope of protection is determined by the claims. However, the description and the drawings are to be referenced for the interpretation of the claims. Individual features or combinations of features from the various exemplary embodiments shown and described can represent independent inventive solutions in themselves. The problem to be solved, upon which the independent, inventive solutions are based, can be derived from the description.
[0065] As a matter of form and by way of conclusion, it is noted that, to improve understanding of the structure, elements have partially not been shown to scale and/or enlarged and/or shrunk.
[0066] Although only a few embodiments of the present invention have been shown and described, it is to be understood that many changes and modifications may be made thereunto without departing from the spirit and scope of the invention.
