Description

Protective helmet and device for its drying and

storage

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 is increasing, winter sports equipment, such as skis, snowboards,

To lend racing sleds and their accessories, such as shoes and boots, constantly. This includes protective helmets for winter sports.

While for the rental of, for example, ski boots, shelves are commercially available in which the shoes are stored on heated shelves and dried, no facilities are known for the rental of winter sports helmets to keep them clear and dry at the same time.

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

CONFIRMATION COPY reaches the helmet according to claim 9. In the dependent claims 2 to 8 or 10 to 21 are preferred embodiments of the protective helmet according to the invention or the inventive

Device reproduced.

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 with winter sports helmets are the

Ventilation openings preferably attached to a point of the helmet and designed so that the air can escape from the interior of the helmet, but the cold airstream through the ventilation openings does not blow into the interior of the helmet, ie in the longitudinal direction of the helmet in the middle region and the occipital region, 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. B. hard plastic or polycarbonate and a core,

preferably made of foam, for example polystyrene. The foam core can be provided with a lining, preferably made of an air-permeable textile material, such as

coarse mesh or a soft fabric for

Sweat receptacle be provided with pads to adapt the helmet to the head size. The fairing and the pads can For example, with a Velcro with the

Foam core connected.

The ventilation opening, through which with a nozzle of the

Helmet drying and storage device warm, dry air is blown into the helmet interior, is formed by an opening in the outer shell, which communicates preferably with channels in the core, through which the warm air in the

Helmet interior is blown.

The ventilation opening, through which the warm air in the

Helmet interior is blown in a winter sports helmet preferably in the back of the helmet, for example, in the lower half of the occiput, preferably provided in the helmet transverse direction in the middle of the helmet, but could also be on another, any helmet

placed position.

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.

To the space requirement of winter sports helmet significantly

reduce, therefore, the two are according to the invention

Earmuffs of the helmet preferably designed so that they can be folded towards each other inwardly toward the respective opposite helmet side and in the folded state

detachably connectable to each other. For this, the earmuffs are hinged to the helmet. For releasable connection can Velcro, a

Plug connection, for example on the chin guard band of

Winter sports helmet, a push button connection, one

Magnetic connection or the like may be provided.

Preferably, the ventilation opening, through which the warm air is blown into the helmet, at the same time serve to hold the protective helmet, in 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 attached helmet can wobble back and forth, the nozzle preferably additionally engages in one

Recess in the helmet. This recess may be aligned with the opening in the outer shell opening in the

However, it is preferably 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, that extends from the rear towards the front of the helmet. The length of the opening in the outer shell in the

Recess extending nozzle portion may for example be 3 to 20 centimeters.

The nozzle for insertion into the ventilation opening can

be arranged horizontally to the plugged on it

hold. Preferably, the nozzles which protrude into the

Ventilation be plugged, but at an angle or

vertically upwards. If the helmet next to the ventilation opening for blowing in the warm air further ventilation openings, the ventilation opening, through which the warm air is blown, with the other ventilation openings of the helmet through channels, for example, between the outer shell and the

Foam core connected to each other

communicate. This ensures that the warm air blown in through the nozzle is directed to the individual

Ventilation openings distributed and thus over several

Ventilation holes are blown to dry inside the helmet.

Preferably, between the outer shell and the

Foam core provided a closure plate, which is pushed between a forward, ie in the direction of the front area of the helmet open position 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 holes are closed, lockable.

In this case, the rear edge of the closure plate in the

Closing position preferably at the opening in the

Outer shell through which the nozzle is inserted, so

arranged that the closure plate upon insertion of the nozzle into the opening in the outer shell through the nozzle in the

Open position pushed.

This ensures that to dry the helmet

all vents are open, so a

maximum passage of 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 magnet is provided. Of course, the at least one part made of ferromagnetic material may also be formed by a permanent magnet.

So that the helmet held by the helmet drying and storage device is secured against rotation, are

preferably at least two spaced-apart parts of ferromagnetic material provided on the helmet,

preferably two parts of ferromagnetic material

on both sides of the ventilation opening of the helmet.

The inventive device for drying and

Storage of the helmet is preferably by a

Frame, shelf or the like formed, which preferably has a plurality of nozzles for supplying warm, so preferably over room temperature heated and dry air, for example, in a rental company a large number of

Keep winter sports helmets at the same time and dry them.

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. About these

Lines, the warm air is thus distributed to the individual nozzles.

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 device for drying and storing the helmets, 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 provided for example in the shelf or frame pipe for supplying the warm air

connectable.

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. It would also be conceivable variant, in which a stable bridge to

Recording two magnets attached to a flexible band hangs, and in this way allows a pendulum movement, which in turn an unintentional release of the magnetic connection

prevented. The magnets on the helmet drying and storage device can, for example, cylindrical or conical

be educated. The attachment of the magnets to the

Connector can be made by friction, positive locking,

Screwing, countering or the like done. Also, the magnets may be injected into the connector.

The part of ferromagnetic material is preferably formed by a plate, which in an opening in the

Outer shell of the helmet is inserted. To attach the plate, the plate may have a flange which the

Opening in the outer shell engages behind and with her

for example, is glued.

Figure 7 in a side view several at one

Pipe section of a helmet drying and - storage device sequentially lined helmets according to Figure 5, each held by a connector of Figure 6; and

8 shows a section through an earmuffs of the helmet of Figure la along the line VIII - VIII.

According to FIG. 1 a and FIG. 2 a, 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 formed according to Figure 4a and Figure 4b for insertion of a nozzle 11 for supplying warm air according to the arrow 12 and for holding 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 when wearing the helmet, although from the interior of the helmet. 1

can escape, but the cold wind through the

Ventilation holes 2 to 4 can not blow into the interior of the helmet 1. The helmet 1 has a hard outer shell 14 and a foam core 15.

As illustrated by the ventilation openings 2 to 5, the ventilation openings through openings 16 to 18 in the outer shell 14 and openings 19 to 21 in the

Foam core 15 is formed, which communicate with the openings 16 to 18 in the outer shell 14 and aligned.

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 in the helmet transverse direction in the middle in

Hinterkopfbereich of the helmet 1 is provided.

In order to fix the helmet 1 plugged onto the nozzle 11, a side of the foam core 15 facing the opening 18 on the outer shell 14 in the foam core 15 extends upward and forward in the helmet longitudinal direction

Recess 22 provided.

Between the outer shell 14 and the foam core 15, a closure plate 23 is arranged, which between a front open position shown in Figure la and Figure lb, in which the ventilation openings 2 to 4 are opened, and one shown in Figure 2a and Figure 2b rear

Closed position in which the ventilation openings are closed 2 to 4, is displaced.

As can be seen from FIG. 4 a, 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 during insertion of the nozzle 11 is moved to the open position, as shown in Figure 4b.

For displacement of the closure plate 23, a handle or the like handle 28 is provided on the outer side of the outer shell 14, further in the Helmlängsrichtung the

Outer shell 14 extending slot 25 through which the handle 28 is connected to the closure plate 23. (see Figures la and 2a).

According to Figure 3, the frame 13 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 extending substantially vertically upwards. Thus, the helmets 1 in the frame 13th

clearly arranged, 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 to the outlet of the moist air during skiing or other winter sports, on the other flows over the

Ventilation opening 5 according to the arrows 27 (Figure 4b) warm dry air into the interior of the helmet 1 and finally it is used for secure fixation of the helmet in the frame thirteenth

The lines 26 of the frame 13 may be formed by pipes and the nozzle 11 by connected to the pipes pipe socket, which, as shown in Figure 4a and 4b, may also be formed angularly.

The helmet 31 according to FIG. 5 differs from the helmet 1 according to FIGS. 1 a, 1 b, 2 a, 2 b and 4 a and 4 b primarily in that for holding the helmet 31 on a helmet-dry and Storage device instead of the opening formed for insertion of a nozzle 11 ventilation opening 5 in the helmet according to Figure 5 on both sides of the vent opening 32 each have a part 33a, 33b of ferromagnetic material at the back of the head portion of the helmet 31 is attached.

For this purpose, as illustrated in FIG. 6, 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 hold the helmet 31 therewith to the helmet drying and storage device.

The dashed lines shown in Figure 6 magnets 34a, 34b are arranged on either side of a nozzle 36 also shown by dashed lines, through which warm, dry air, as illustrated by the arrow 37, is blown into the vent opening 32 of the helmet 31, wherein the warm, dry air the nozzle 36 is supplied via the pipe 38, which is provided with corresponding openings 40 (see also Figure 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 is transmitted through Connector 39 made of a rubber-elastic plastic.

The connecting piece 39 has a sleeve 41, into which the pipe 38 is inserted, which, as shown by way of example in FIG. 7, has openings 40 for this, in order to provide the warm,

supply 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 has the corresponding opening 40 in the

Piping 38 connects to 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.

To increase its flexibility, further slots 45 in the arms 44a, 44b and the portion 43 of a

rubber-elastic material existing connector 39 is provided.

The bridge 42 is provided on its side facing the helmet 31 with a sealing lip 46, which of the two

Magnets 34 a, 34 b held helmet 31, the ventilation opening 32 in the helmet 31 encloses airtight.

Thus, the two magnets 34a, 34b in contact with the

ferromagnetic parts 33a, 33b can occur on the helmet 31, close the magnets 34a, 34b down either flush with the sealing lip 46 or the rubber-elastic sealing lip 46 projects slightly downwards over the two magnets 34a, 34b. From Figure 7 it can be seen that on a pipe 38 a helmet drying and storage device

For example, on the shelf or a frame of a rental company a variety of helmets 31 can be arranged to save space and clear, in Figure 7 the

Connector on the right pipe is omitted 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.

It can also be seen from FIG. 7 that for a space-saving arrangement of the helmets 31, the helmets 31 should occupy as little space as possible 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 padded with

Earmuffs 48a, 48b provided, wherein the earmuffs 48b, which is arranged on the other side helmet, not visible in the drawing, and indicated in Figure la by an arrow.

The two earmuffs 48a, 48b are foldable towards each other inwardly, as shown for the earmuffs 48a by the arrow 49 in Figure la, and releasably connected together in the folded state (Figure 7).

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 shown in Figure 8. Thereafter, the earmuff 48a (and also the earmuff 48b) attached, for example, to the outer shell 14 of the helmet 1 with rivets 55, for example, consists of a padding 52 formed by an outer skin 53 and an inner skin 54, for example a fabric. is included. in the

Area of the pivot axis 51, the pad 52 is omitted and the outer skin 53 and the inner skin 54 are connected to each other, for example, welded or sewn.

For detachable connection of the two folded inside

Earmuffs 48a, 48b may be provided a hook and loop fastener, so for example a Velcro 56a on one

Earmuffs 48a and Velcro 56b, for example, on the outside of the chin guard band 8, the one on the other

Earmuffs 48b is attached, as shown in Figure la. By turning the chin guard band 8 about its longitudinal axis inwards, the hook and loop tape 56b can then be fixed to the hook and loop fastener 56a.

According to FIG. 7, the fixed earmuffs 48a) and (48b) folded inwardly about the pivot axes 51 achieve a considerable additional space saving of the helmets 51 on the conduit 38 of the helmet drying and storage device.
