Description

The invention relates to a protective helmet, in particular a winter sports helmet, and a device for drying and storage of the helmet.

Due to the rapid technical development and increasing variety of winter sports equipment and their accessories, the trend to borrow winter sports equipment, such as skis, snowboards, racing sleds and their accessories, such as shoes and boots, is steadily increasing. This includes protective helmets for winter sports.

For rental, for example, of ski boots, shelves are commercially available in which the shoes are stored on heated shelves and dried, also for the rental of winter sports helmets facilities are known to keep clear and dry at the same time, see, eg DE 297 16 924 U1 ,

Since there is sometimes a hectic operation in a rental company, a quick access is just as important for helmets as a quick drying of the helmets, which must be disinfected and dried after each rental.

The object of the invention is therefore to provide a device with the helmets, especially winter sports helmets, kept clear and can be dried immediately.

This is inventively with the winter sports helmet according to claim 1 and the device for drying and storage reaches the helmet according to claim 9. In the dependent claims 2 to 8 or 10 to 22 preferred embodiments of the protective helmet according to the invention or the device according to the invention are shown.

According to the invention, the protective helmet is designed for mounting on a device for drying and storing the helmet and provided with a ventilation opening through which warm air can be fed into the interior of the helmet with a nozzle from the helmet drying and storage device.

It may be one of several ventilation openings with which sports helmets are usually provided.

Especially in winter sports helmets, the ventilation openings are preferably attached to a point of the helmet and designed so that the air from the interior of the helmet can escape, but the cold wind through the ventilation holes does not blow into the interior of the helmet, ie in the longitudinal direction of the helmet in the middle Area and in the occipital area, but not in the forehead area. In contrast, for example, in a summer sports helmet, for example for cyclists, the ventilation openings are preferably provided in front, so the front side.

The helmet has, as usual, preferably an outer shell, for. As hard plastic or polycarbonate and a core, preferably made of foam, for example, polystyrene. The foam core may be provided with a lining, preferably of an air-permeable textile material, such as a coarse-meshed fabric or a soft fabric for perspiration absorption, further with pads to adapt the helmet to the head size. The fairing and the pads can be connected for example with a Velcro fastener with the foam core.

The vent opening, through which hot, dry air is blown into the helmet interior with a nozzle from the helmet drying and storage device, is formed by an opening in the outer shell, which preferably communicates with channels in the core through which the warm air enters the helmet interior is blown.

The ventilation opening through which the warm air is blown into the helmet interior is preferably provided in the back of the helmet, for example in the lower half of the back of the head, preferably in helmet transverse direction in the middle of the helmet in a helmet, but could also at another, Any position placed on the helmet.

Winter sports helmets are generally provided with earmuffs that are more or less thickly padded and generally protrude far beyond the outer shell of the helmet. Through the earmuffs, the winter sports helmet thus takes a considerable additional volume, which precludes the scarce space, for example, in a rental company for winter sports equipment.

In order to significantly reduce the footprint of the winter sports helmet, therefore, the two earmuffs of the helmet are preferably designed according to the invention so that they are mutually releasably connectable to each other inwardly toward the respective opposite helmet side and in the folded state.

For this, the earmuffs are hinged to the helmet. For releasable connection can be provided a Velcro connection, a connector, for example on the chin guard of the winter sports helmet, a push-button connection, a magnetic connection or the like.

Preferably, the ventilation opening, through which the warm air is blown into the helmet, at the same time serve to hold the protective helmet, namely, that it is designed for insertion of the nozzle, with the warm air from the helmet drying and storage device can be fed.

So that the nozzle inserted into the ventilation opening of the outer shell does not only engage the edge of the opening of the outer shell and thus the plugged-on helmet can wobble back and forth, the nozzle preferably additionally engages in a recess in the helmet. This recess may be an opening in the foam core aligned with the opening in the outer shell, but preferably it is formed by a recess in the foam core on the outer shell facing side of the foam core, said recess preferably in the longitudinal direction of the helmet, ie from behind extends towards the front of the helmet. The length of the nozzle section extending through the opening into the outer shell into the recess can be, for example, 3 to 20 centimeters.

The nozzle for insertion into the ventilation opening may be arranged horizontally to hold the helmet attached thereto. Preferably, however, the nozzles which are inserted into the ventilation opening, project obliquely or vertically upwards.

If the helmet has additional ventilation openings adjacent to the ventilation opening for blowing in the warm air, the ventilation opening, through which the warm air is injected, can be connected to the remaining ventilation openings of the helmet by channels, for example between the outer shell and the foam core, in order to communicate with each other , This ensures that the warm air blown in through the nozzle is distributed to the individual ventilation openings and is therefore blown through several ventilation openings for drying in the interior of the helmet.

Preferably, a closure plate is provided between the outer shell and the foam core, which is arranged between an open position, ie in the direction of the end region of the helmet, in which the ventilation openings are open, and a rear, d. H. moved to the back of the head area closed position in which the ventilation openings are closed, can be closed. The rear edge of the closure plate in the closed position is preferably arranged at the opening in the outer shell, through which the nozzle is inserted, such that the closure plate is pushed through the nozzle into the open position when the nozzle is inserted into the opening in the outer shell.

This ensures that all the ventilation openings are open for drying the helmet, so a maximum passage of the air from the interior to the outside is ensured during drying.

To adjust the width of the ventilation openings when wearing the helmet, the closure plate with a handle, z. B. with one of the outer shell to the outside outstanding handle, which is connected by a extending in Helmlängsrichtung slot in the outer shell with the closure plate.

According to another embodiment, the protective helmet has at least one part made of ferromagnetic material in order to hold it to the helmet drying and storage device, which is provided with at least one magnet, preferably permanent magnets. Of course, the at least one part made of ferromagnetic material may also be formed by a permanent magnet.

In order for the helmet held by the helmet drying and storage device to be secured against rotation, preferably at least two spaced-apart parts of ferromagnetic material are provided on the helmet, preferably two parts of ferromagnetic material on either side of the ventilation opening of the helmet.

The device according to the invention for drying and storing the protective helmet is preferably formed by a frame, shelf or the like, which preferably has a plurality of nozzles for supplying warm, so preferably above room temperature and dry air, for example, in a rental company a large number of winter sports helmets simultaneously to store and to be able to dry.

The nozzles are connected to each other by a conduit, such as a hose or pipe, through which the warm, dry air is supplied.

In this case, the shelf or frame preferably has a plurality of superposed lines, which with a plurality juxtaposed nozzles for supplying the warm, dry air are provided in the helmets. The warm air is thus distributed to the individual nozzles via these lines.

In the protective helmets in which the ventilation opening is designed for holding the protective helmet for insertion of the nozzle, the nozzles for attaching the helmets can extend from the lines in the horizontal direction, but preferably they extend upwards. The length of the nozzles is preferably dimensioned such that the helmet mounted thereon rests with the back of the head region of the outer shell on the line or other stop. As a result, the helmets plugged onto the nozzles are largely fixed.

The means for drying and storing the helmets, which are provided for mounting with at least one part of a ferromagnetic material, has at least one magnet, which attracts the at least one part of ferromagnetic material to the protective helmet.

The at least one magnet is arranged on the nozzle. Preferably, it is so resiliently attached to it that it rests flat against the at least one part of ferromagnetic material of the protective helmet. This prevents the helmet hanging from the helmet drying and storage device from becoming loose during a tilting or pendulum movement and thus from falling down, for example, in the case of accidental knocking.

For resilient attachment of at least one magnet to the nozzle, the magnet may be connected to the nozzle via a rubber-elastic body.

For protective helmets, which are provided on both sides of the ventilation opening with a part of a ferromagnetic material, the helmet drying and storage device comprises two magnets, which are preferably interconnected by a bridge.

In this case, the bridge can be formed by a connecting piece, wherein the ventilation opening of the protective helmet between the two magnets is arranged when the helmet adheres to the helmet drying and storage device.

The connector is provided with the nozzle, through which the warm air is blown into the helmet. The nozzle of the connector is connectable to the example provided in the shelf or frame line for supplying the warm air.

In this case, the connecting piece has a sealing lip arranged around the nozzle, which encloses the ventilation opening of the protective helmet airtight when held by the two magnets protective helmets. To do this, the two magnets must either be flush with the sealing lip or the sealing lip must protrude over the two magnets.

Preferably, the connector is made of rubber-elastic material. It can be formed as a one-piece molding. The connector can also be designed as a multi-part, articulated component. Also conceivable would be a variant in which a stable bridge for receiving two magnets attached to a flexible band attached, and in this way allows a pendulum movement, which in turn prevents unwanted release of the magnetic connection.

The magnets on the helmet drying and storage device may be formed, for example, cylindrical or conical. The attachment of the magnets to the connector can be done by frictional engagement, positive locking, screwing, locking or the like. Also, the magnets may be injected into the connector.

The part of ferromagnetic material is preferably formed by a plate which is inserted into an opening in the outer shell of the helmet. To attach the plate, the plate may have a flange which engages behind the opening in the outer shell and is glued to it, for example.

According to FIG. 1a and FIG. 2a a winter sports helmet 1 has a plurality of ventilation openings 2 to 7. The chin guard band of the helmet 1 is denoted by "8" and the face opening of the helmet 1 by "9".

The ventilation opening 5 in the occipital region of the helmet 1 is according to Figure 4a and Figure 4b for inserting a nozzle 11 for supplying warm air according to the arrow 12 and for mounting the helmet 1 on a frame 13 for drying and storage and a plurality of helmets 1 ( FIG. 3 ).

The ventilation openings 2, 3 and 4 are mounted in the central region of the helmet and designed so that the moist air while wearing the helmet can escape from the interior of the helmet 1, but the cold wind through the ventilation holes 2 to 4 not in the interior of the helmet 1 can blow.

The helmet 1 has a hard outer shell 14 and a foam core 15.

As illustrated by the vents 2 to 5, the vents are formed through openings 16 to 18 in the outer shell 14 and openings 19 to 21 in the foam core 15 which communicate with the openings 16 to 18 in the outer shell 14.

The ventilation opening 5 for inserting the nozzle 11 for supplying dry, warm air 12 and for holding the helmet 1 in the frame 13 is provided in the helmet transverse direction in the center in the occipital region of the helmet 1.

In order to fix the helmet 1 plugged onto the nozzle 11, a recess 22 extending upwards and forwards in the helmet longitudinal direction is provided in the foam core 15 from the side of the foam core 15 facing the outer shell 14.

Between the outer shell 14 and the foam core 15, a closure plate 23 is arranged between an in FIG. 1a and FIG. 1b illustrated front open position in which the ventilation openings 2 to 4 are opened, and a in Figure 2a and 2b shown rear closed position in which the ventilation openings are closed 2 to 4, is displaceable.

How out FIG. 4a As can be seen, the rear edge 24 of the closure plate 23 is arranged at the opening 18 in the outer shell 14 of the ventilation opening 5 such that the closure plate 23 through the nozzle 11 upon insertion of the nozzle 11 is moved to the open position, as in FIG. 4b shown.

For displacing the closure plate 23, a handle or similar handle 28 is provided on the outer side of the outer shell 14, furthermore a slot 25 extending in helmet longitudinal direction of the outer shell 14, via which the handle 28 is connected to the closure plate 23. (see. FIGS. 1a and 2a ).

According to FIG. 3 the frame 13 has a plurality of superposed lines 26, via which the hot air is supplied to the nozzles 11, which are arranged side by side on the lines 26 and extend substantially vertically upwards. Thus, the helmets 1 are arranged clearly in the frame 13, for example, with its inside facing the viewer, as shown.

The ventilation opening 5 thus has three functions. That is, it serves on the one hand as the other ventilation openings 2 to 4 and 6 and 7 for the discharge of moist air during skiing or other winter sports, on the other hand flows through the ventilation opening 5 according to the arrows 27 (FIG. FIG. 4b ) warm dry air into the interior of the helmet 1 and finally it serves for the secure fixation of the helmet in the frame thirteenth

The lines 26 of the frame 13 may be formed by pipes and the nozzles 11 by connected to the pipes pipe socket, as in FIGS. 4a and 4b represented, may also be formed angular.

The helmet 31 after FIG. 5 differs from the helmet 1 after FIG. 1a, 1b, 2a, 2b and 4a and 4b especially in that for holding the helmet 31 on a helmet dry and - Storage device instead of the trained for inserting a nozzle 11 ventilation opening 5 in the helmet after FIG. 5 on both sides of the ventilation opening 32, a part 33a, 33b of ferromagnetic material is attached to the occipital region of the helmet 31.

In addition, as in FIG. 6 For example, the helmet-drying and storage device for each helmet 31 has two magnets 34a, 34b which magnetically attract the ferromagnetic parts 33a, 33b to the helmet 31 as indicated by the double arrows 35a, 35b and thus dry the helmet 31 on the helmet - and keep storage.

In the FIG. 6 Dashed magnets 34a, 34b are arranged on either side of a nozzle 36 also shown in dashed lines, through which warm, dry air, as illustrated by the arrow 37, is blown into the ventilation opening 32 of the helmet 31, wherein the warm, dry air of the nozzle 36 via the pipe 38 is supplied, which is provided with corresponding openings 40 (see also FIG. 7 ).

In order for the magnets 34a, 34b to lie flat against the ferromagnetic parts 33a, 33b formed by small plates, the magnets 34a, 34b are resiliently fastened to the nozzle 36.

In order to obtain the required degrees of freedom for surface contact with the ferromagnetic parts 33a, 33b, however, the magnets 34a, 34b may also be fastened in other ways, for example with flexible traction means, such as strings or tapes.

According to FIG. 6 the surface contact of the magnets 33a, 33b on the ferromagnetic parts 33a, 33b of the helmet by a Connector 39 made of a rubber-elastic plastic.

The connecting piece 39 has a sleeve 41, in which the pipe 38 is inserted, which, as in FIG. 7 exemplified, having openings 40 to supply the hot, dry air to the nozzle 36.

Furthermore, the connecting piece 39 has a bridge 42, in which the two magnets 34a, 34b are fixed, and a portion 43 which connects the corresponding opening 40 in the pipe 38 with the nozzle 39.

To stabilize further two arms 44a, 44b are provided which extend from the sleeve 41 to the one or the other end of the bridge 42.

In order to increase its flexibility, further slots 45 are provided in the arms 44a, 44b and the portion 43 of the rubber-elastic material connecting piece 39.

The bridge 42 is provided on its side facing the helmet 31 with a sealing lip 46 which encloses the ventilation opening 32 in the helmet 31 airtight when held by the two magnets 34a, 34b helmet 31.

So that the two magnets 34a, 34b can come into contact with the ferromagnetic parts 33a, 33b on the helmet 31, the magnets 34a, 34b are either flush with either the sealing lip 46 or the rubber-elastic sealing lip 46 is above the two magnets 34a, 34b something down in front.

Out FIG. 7 It can be seen that a plurality of helmets 31 can be arranged in a space-saving and clear manner on a pipeline 38 of a helmet drying and storage device, for example, on the shelf or a rack of a rental company, wherein FIG. 7 the connector on the pipe is omitted on the right to see the opening 40.

When a helmet 31 is removed, only the nozzle 36 in the connector 39 needs to be plugged, for example.

Out FIG. 7 is also apparent that for a space-saving arrangement of the helmets 31, the helmets 31 should occupy as little space in the horizontal direction. For this reason, the ferromagnetic pieces 33a, 33b are disposed on the helmet 31 in the lower half 47 of the occipital region 48 of the helmet 31.

The winter sports helmets 1, 31 are provided with padded earmuffs 48a, 48b, wherein the earmuffs 48b, which is disposed on the other side of the helmet, can not be seen in the drawing, and in FIG. 1a indicated by an arrow.

The two earmuffs 48a, 48b are hinged inwardly toward each other, as for the earmuff 48a by the arrow 49 in FIG FIG. 1a shown, and in the folded state ( FIG. 7 ) releasably connected to each other.

In order to fold or pivot inwardly, a pivot axis 51 is provided. The pivot axis 51 can be formed for example by a film hinge, as in FIG. 8 shown.
