Definitions

  • the present invention relates to a helmet, for example a bicycle helmet, with a helmet body, a ventilation hole, a cover which at least partially covers the ventilation hole, and an electrical energy store.
  • Such a helmet serves the safety of a wearer of the helmet, for example a cyclist.
  • a helmet serves the safety of a wearer of the helmet, for example a cyclist.
  • the use of such a helmet is not limited to cyclists, even riders of a unicycle, quads, motorcycles, scooters, skateboards or users of inline skates or the like can wear such a helmet.
  • Ventilation holes in the helmet body contribute to an increase in wearing comfort, as this air can circulate on the head of the helmet wearer.
  • one or more ventilation holes covering covers the helmet carrier is protected from micro parts, which can penetrate into the ventilation holes, such as insects, Ast Glachen or the like.
  • the ventilation effect of the ventilation holes can be improved by a special design of the covers.
  • the integrated into the helmet energy storage is used to supply a power consumer with energy, such as a built-in helmet rear light, which should improve the visibility of the helmet wearer even in poor visibility, for example, at night, in a tunnel or fog.
  • a tail light is attached to a back of the helmet, for example, by being inserted in a recess provided in the helmet body or attached to an outer surface of the helmet.
  • the energy store is typically in the form of a battery integrated in the backlight.
  • the battery has only a limited life, which is the shorter, the more often the rear light is used.
  • the user of the helmet must therefore replace the battery regularly. However, this proves to be uncomfortable in practice.
  • a helmet having the features of claim 1 and in particular by at least one photovoltaic cell for charging the energy store, which is provided on the cover.
  • the invention is based on the general idea to equip the helmet with a rechargeable energy storage and a photovoltaic cell for charging the energy storage. In normal use of the helmet, that is not exclusive use and storage of the helmet in darkness, this ensures that the energy storage always has enough energy to power a connected power consumers with energy.
  • the automated charging of the energy storage such as a built-in helmet or attached to the helmet accumulator by means of the photovoltaic cell the user of the helmet remain uncomfortable battery replacement and associated costs spared.
  • a plurality of photovoltaic cells can be combined in a solar module in order to provide a voltage or a sufficient current required for charging the energy store.
  • the at least one photovoltaic cell can in principle be permanently connected to the energy store. In this case, however, an example of defect-related replacement of photovoltaic cell and / or energy storage is only possible together. Preference is therefore given to a design in which the at least one photovoltaic cell and the energy storage are releasably connected to each other, for example by means of a plug connection, so that if necessary, an individual exchange of photovoltaic cell or energy storage is possible.
  • the assembly or disassembly of the photovoltaic cell is simplified because it can be attached to the helmet body together with the cover, which is typically formed like the photovoltaic cell in this way.
  • the cover serves as a support structure for the photovoltaic cell and thus fulfills a dual function in that at the same time it also at least partially covers the associated ventilation hole in order to prevent the penetration of microparts and, if appropriate, the aerodynamics and / or the ventilation effect, i. ultimately to optimize the air circulation at the head of the helmet wearer.
  • ventilation hole in this context, an opening to understand, which extends from an inner side of the helmet through the helmet body to an outside of the helmet.
  • the surface of the photovoltaic cell is preferably smaller than the surface of the cover and chosen in particular so small that covered by the cover ventilation hole or more through the cover Covered ventilation holes is not completely closed or closed by the photovoltaic cell.
  • the helmet body can be made, for example, from a rigid foam, in particular expanded polystyrene rigid foam, hard foam being particularly well suited for absorbing shocks.
  • the helmet body may further be at least partially provided with an outer shell, which is made for example of a thermoplastic such as polyvinyl chloride, polyethylene terephthalate, polycarbonate or acrylic-butadiene-styrene.
  • the helmet body may be connected, for example by gluing, molding or foaming with an inner side of the outer shell.
  • the cover is detachably attached to the helmet.
  • the releasable connection can be realized for example by means of snaps, a hook and loop fastener or a zipper.
  • the detachable connection makes it easy to attach the cover and photovoltaic cell to the helmet. Once the photovoltaic cell and cover are not needed, they can easily be removed from the helmet. In heavy rain they can also be removed and replaced by a rain cover. Basically, common rain covers for the helmet can also be created on the cover and photovoltaic cell. It is also possible that the helmet was initially shipped with a detachable cover without a photovoltaic cell. Due to the detachable connection between the helmet and cover then a simple retrofit can be made by a cover with photovoltaic cell.
  • the cover has a grid structure with a multiplicity of openings.
  • turbulences of the wind are generated, whereby a ventilation effect of the or each under the cover located ventilation hole is improved.
  • a grid structure may be made of a plastic or metal material, for example.
  • the openings are smaller than the or each vent hole.
  • the openings may e.g. be designed as micro-openings, which have a diameter in the micrometer range.
  • the fact that the openings are smaller than the or each ventilation hole, on the one hand the ventilation effect of the cover and on the other hand, the protection against penetrating insects or the like can be improved.
  • the cover is a curved structure and / or rigid in itself. Due to the curved design of the cover this can be adapted to the shape of the helmet. In particular, the curvature can be convex and follow the contour of the helmet. In addition, the cover can be stiff in itself. As a result, the strength of the cover is increased and also protects the photovoltaic cell, since the cover does not yield to an external force.
  • the photovoltaic cell is absorbed by the cover deformation-free. This means that the photovoltaic cell can be attached to the cover without being deformed, for example, bent, thereby preventing breakage or other damage to the photovoltaic cell.
  • the photovoltaic cell is arranged in the region of an apex of the helmet. Under the vertex The helmet is the highest point on the top of the helmet to understand. Due to the orientation of the photovoltaic cell in this area, when the helmet is worn during the day an optimal incidence of light and thus optimum energy supply into the energy store are made possible.
  • the cover can in principle also be positioned so that the orientation of the photovoltaic cell is adapted to the respective incidence of light. In this way, the respective incidence of light can be optimally utilized even in the early morning hours and in the late evening hours.
  • the photovoltaic cell is connected directly or indirectly to the energy store.
  • a direct connection of the photovoltaic cell with the energy storage can be realized for example by means of a power cable.
  • a control unit can be connected between the photovoltaic cell and the energy store.
  • the control unit may each be connected by means of a suitable electrical line, e.g. be connected by means of a power cable to the photovoltaic cell and the energy storage.
  • a read-out unit and / or a counting unit can be connected between the photovoltaic cell and the energy store.
  • the energy storage device can have a connection by means of which the energy store can also be charged externally.
  • a connection can be designed, for example, in the form of a USB socket. Due to the possibility of additional external energy supply, a sufficient state of charge of the energy storage can be ensured even at low incidence of light.
  • the energy storage is arranged in a recess of the helmet body, in particular together with an associated power consumers is particularly advantageous.
  • a secure housing is realized, on the other hand, a streamlined shape of the helmet can be maintained, since the energy storage does not have to be mounted on the outer shell of the helmet.
  • a power consumer associated with the energy storage device may be arranged in the same or an adjacent recess. The recess is advantageously arranged on a rear side of the helmet, in particular if the current consumer is a tail light.
  • a power cable for connecting the energy store with the photovoltaic cell and / or the power consumer at least partially passes through a channel of the helmet body.
  • a power cable may be led from the photovoltaic cell through a vent hole into the helmet interior or into the helmet body. Through a channel from the ventilation hole to the energy storage device located in the recess, an electrical connection can be realized without the helmet wearer experiencing a loss of comfort due to the power cable.
  • a power cable connecting them can also be routed through a channel in the helmet body.
  • connection of a power cable to the photovoltaic cell, the energy storage and / or the power consumer by means of a detachable plug connection.
  • the power consumer, the energy storage and / or the control unit and these connecting lines can be arranged in a common housing, in particular of the power consumer.
  • a compact component is created, which can be easily inserted into the helmet body and connected, for example by means of a power cable to the photovoltaic cell.
  • the power consumer is an optical or acoustic output unit.
  • the current consumer can be embodied in particular in the form of a helmet tail light, by means of which the visibility of the helmet wearer in traffic is improved.
  • a helmet tail light is arranged in a recess on the helmet back.
  • the power consumer can also be designed as an acoustic output unit, for example as speakers or headphones.
  • the power consumer may also be any other electrical or electronic component, for example a charger, e.g. for a mobile phone, or even a sensor, in particular for a safety application, such as for the detection of an accident.
  • a charger e.g. for a mobile phone
  • a sensor in particular for a safety application, such as for the detection of an accident.

Specifically, the solar module 23 is pushed into a pocket of the cover 19 and thus absorbed without deformation in the cover 19, whereby, inter alia, a fracture of the solar module 23 is prevented. It is understood, however, that for attaching the solar module 23 to the cover 19, a variety of other form-fitting, non-positive and / or cohesive mounting options come into question, for. Plugging, gluing, latching, screwing, etc.
