Definitions

  • the present invention relates to a hose box with the features of independent claim 1.
  • Hose boxes are known to have a hose reel, by means of which hoses, for example garden hoses, can be wound up in an orderly manner and unwound from the hose reel when in use.
  • hoses for example garden hoses
  • the problem is that a hose coupled to the hose reel is often very difficult to access and can therefore only be replaced with considerable effort.
  • the present invention is therefore based on the object of providing a hose box which has a simple structure and to which the hose can be easily coupled and decoupled.
  • the forces acting on the coupling connection of the hose should be reduced with the present hose reel.
  • the invention relates to a hose box equipped with a changeable and/or replaceable battery pack for motorized winding of a hose, in particular a garden hose.
  • the hose can in particular be an exchangeable and/or replaceable hose.
  • the hose box includes a housing.
  • the housing can be formed in one piece or preferably in several parts. In a multi-part design, the housing can be formed by at least two housing halves.
  • a hose drum is arranged within the housing and rotates about an axis of rotation, on which the hose can be wound.
  • the hose drum includes a drum shell and drum disks arranged thereon.
  • the drum shell can have at least approximately a cylindrical shape.
  • the drum disks can preferably be arranged and/or attached to the end faces of the drum shell.
  • the drum disks can, for example, be non-positively, positively and/or materially connected, for example coupled, clamped or screwed, to the end faces of the drum shell.
  • the drum disks can each have a round cross section and be of the same size.
  • the drum disks can preferably have a larger diameter than the drum shell, since the drum disks laterally limit the hose wound onto the drum shell.
  • the drum disks can be formed continuously or have at least one or more drum disk openings.
  • the advantage of drum disks with at least one or more drum disk openings can be that the weight of the drum disks and thus the entire hose box can be reduced.
  • the one or more drum disk openings can have a round, square or other cross section.
  • the one or more drum disk openings can each be of the same size or of different sizes.
  • the drum casing comprises at least one cavity with a coupling connection provided therein, to which the hose can be coupled.
  • the hose can be coupled to the coupling connection via a corresponding coupling piece.
  • At least two guide elements are arranged within the cavity in such a way that the hose is guided in a meandering shape around the at least two guide elements at least in sections.
  • the at least two guide elements can also function as a strain relief element, since the meandering guide means that the forces acting on the hose, for example when unwinding, do not act directly on the coupling connection. Due to this, wear and tear on the hose box and in particular of the coupling connection and the hose can be significantly reduced and at the same time their service life can be increased.
  • the coupling connection can be arranged on the side of a drum disk that lies inside the at least one cavity.
  • the coupling connection can in particular be arranged centrally or off-center on the side of the drum disk that lies inside the at least one cavity.
  • the coupling connection can be coupled to a water connection via appropriate connecting lines.
  • the at least two guide elements can be bent or curved at least in sections.
  • the at least two guide elements can have the same bend or a different bend.
  • the at least two guide elements can be curved convexly or concavely or similarly.
  • the at least two guide elements can also be semicircular or have an oval shape or the like.
  • the at least two guide elements can be arranged at a distance from one another.
  • the at least one cavity has a recess that merges into the drum shell.
  • the recess can have a size that is equal to or larger than the diameter of the hose, i.e. the recess can be designed such that the hose can be guided from at least one cavity via the recess to the drum casing and then wound onto the drum casing. This allows the guidance of the hose to be improved.
  • the drum casing can be reduced at least in sections in order to provide a guide for the hose from at least one cavity to the drum casing.
  • at least one can be used in the area of the recess another guide element may be provided.
  • the guide element can have a concave curvature. The curvature can preferably be formed in such a way that the hose can rest and be guided optimally on this further guide element.
  • the at least one cavity has a cover that can be opened.
  • the cover can have the same curvature or curvature as the drum shell, i.e. the cover can close the at least one cavity in such a way that the cover is also part of the drum shell. This means that the drum shell is designed in several parts, but in particular in two parts.
  • the cover can, for example, be pivotable or at least partially removable.
  • the cover can be pivoted, for example, via any conceivable pivot and/or joint connection or the like.
  • the cover is attached to the drum casing, for example by means of screw and/or clamp connections.
  • the cover can be completely removed by loosening the screw and/or clamp connections.
  • the cover can also be attached to the drum shell using any other detachable fastening means.
  • the cover is formed continuously or at least has one or more openings.
  • the at least one or more openings can, for example, have a round, square or oval cross section or the like.
  • the hose can be placed over the recess into the cavity and then around the at least two guide elements.
  • the hose can be decoupled from the coupling connection and then removed from the guide elements and pulled off via the recess.
  • the housing of the hose box has an access opening with a removable housing section element, via which access to the drum casing and its cover is possible.
  • the removable housing section element can be formed, for example, in the form of a lid or the like.
  • the housing section element can be attached to the housing, for example, via releasable non-positive or positive connections, such as screw and/or clamp connections. It may also be conceivable that the housing section element is pivotably attached to the housing via a corresponding joint or other pivoting means.
  • the drum shell can also include at least one further cavity within which the drive unit is arranged.
  • the drive unit can be formed by an electric motor.
  • the hose box can be assigned an actuation unit, for example in the form of a switch, button or the like.
  • the drive unit can also be controlled wirelessly via at least one external control unit.
  • the operating unit can be, for example, a smartphone, tablet, smartwatch or the like.
  • the hose box has at least one battery pack interface to which the battery pack can be coupled in order to supply the drive unit with electrical energy.
  • the battery pack interface can be electrically connected to the drive unit via cables.
  • the battery pack interface can be provided on an outside of the housing.
  • the battery pack interface can be arranged within a protective housing.
  • the protective housing can, for example, be pivotable or completely removable.
  • a sealing element can also be assigned to the protective housing in order to at least largely prevent the ingress of moisture or dust or the like.
  • the battery pack can be designed as a removable battery pack, i.e. the battery pack can be replaceable or exchangeable for another battery pack.
  • the battery pack can be designed as a removable battery pack or as a system battery pack, which means that the battery pack, in addition to the hose box present here, can be used universally to supply electrical energy for various electrical devices, for example a power tool, electric garden tool, household appliance, vehicle or the like.
  • the at least one battery pack can comprise at least one battery pack housing, within which at least one battery cell is arranged.
  • the at least one battery cell can in particular be a lithium-ion battery cell.
  • the mention of lithium ions should not be understood as limiting.
  • the at least one battery cell can also be formed, for example, by a nickel-cadmium battery cell, lithium-polymer battery cell or other other conceivable battery cells.
  • several battery cells for example five battery cells or ten battery cells, can also be arranged within the at least one battery pack housing.
  • the multiple battery cells can be connected to one another in series and/or parallel.
  • the battery pack housing can be designed in one or more parts.
  • the battery pack housing can be formed in two parts, consisting of a lower part and an upper part.
  • a line carrier can be provided within the battery pack housing, which is electrically connected to the at least one battery cell.
