Definitions

  • the present invention relates to a hand-held tillage implement, a supply unit for a hand-held tillage implement, a method for producing a hand-held tillage implement and a method for cleaning a soil with a hand-held tillage implement.
  • Hand-held soil cultivation devices are devices for processing a floor by a user, the floor cultivation device being guided by the user with his hands and thus cleaning the floor.
  • Hand-held soil cultivation devices without a motor are known.
  • Motor-driven hand-held soil cultivation devices are also known.
  • Hand-held tillage implements without a motor are easy to operate and can be used flexibly.
  • the processing performance, i.e. the area output with consistent cleaning quality, of hand-held soil cultivation devices without a motor is low, as they become saturated with dirt after a very short time and only spread the dirt around.
  • Motorized walk-behind tillage implements have a higher tillage performance than walk-behind tillage implements without a motor.
  • motor-driven hand-held tillage implements are often bulky and cannot be used flexibly. Such motorized hand-held tillage tools often cannot be used under tables or other objects. This inflexibility results in low efficiency when using a hand-held tillage implement with a motor is used by a user in rooms with obstacles (e.g. tables).
  • the object is achieved by a hand-held tillage device, a supply unit for a hand-held tillage device, a method for producing a hand-held tillage device and a method for cleaning a soil with a hand-held tillage device according to the independent claims.
  • the hand-held soil cultivation device includes a soil part with at least one tool for soil cultivation, at least one motor for driving the tool, a guide handle and a supply unit.
  • the guide stem includes a first section, a second section and a third section. The first section and the third section have longitudinal axes that are arranged essentially parallel. The second section connects the first section to the third section.
  • Such a hand-held soil cultivation device can be used flexibly and efficiently and can be used in particular in areas that are angled or narrow or in which there is furniture such as tables or similar.
  • parallel means that the axes are parallel but not coaxial, i.e. do not have the same axis.
  • the parallel axes are therefore spaced apart.
  • the soil part can include one or more tools for soil cultivation.
  • the soil preparation tool may be intended to clean, polish or otherwise process the soil.
  • the tillage implement may include one or more motors for driving the tool. These can be, for example, electric motors. Other engines can also be used.
  • the guide stem may comprise a plastic or a metal or another material.
  • the guide stem can also consist of several materials or a composite material.
  • the supply unit can be arranged on the guide handle or at another position.
  • the longitudinal axis of the second section can be formed orthogonally to the longitudinal axis of the first section and the longitudinal axis of the third section.
  • the angle between the longitudinal axis of the second section and the longitudinal axis of the first section and/or third section can be in a range of 15° to 85° or 165° to 95°, in particular the angle can be in a range of 35° or 155° or in a range of 45° or 145°.
  • the guide handle of the hand-held tillage implement can include a fourth and a fifth section.
  • the fifth section can be arranged parallel to the first section and the third section.
  • the fifth section can be arranged coaxially with the first section.
  • the fourth section can connect the fifth section and the third section.
  • the fourth section can be shorter than the second section.
  • Such a hand-held soil cultivation device has a particularly user-friendly shape and can be used well to cultivate a soil.
  • the fourth section may be connected to the third section and the fifth section at an angle of 90° each.
  • the angle between the longitudinal axis of the fourth section and the longitudinal axis of the fifth section and/or third section can be in a range of 15° to 85° or 165° to 95°, in particular the angle can be in a range of 35° or 155° or in a range of 45° or 145°.
  • the fourth section may be connected to the third section and the fifth section at angles that substantially correspond to the angles at which the second section is connected to the first section and the third section. The angles at which the second section is connected to the first and third sections and the angles at which the fourth section is connected to the third section and the fifth section may be different.
  • the fourth section and/or the fifth section can be connected to the base part by a connection.
  • the base part can be guided by movements of the guide handle and the surface to be cleaned can be precisely processed.
  • connection can be made of the same material from which the stem is made.
  • the connection can also consist of another material.
  • the connection can be rigid or articulated.
  • the joint can be provided with elastic elements. It is possible that the joint does not include elastic elements.
  • the guide handle can include at least one handle.
  • the handle can be arranged on the first section and/or on the third section of the guide handle.
  • the handle or one of the handles can be spherical or elliptical.
  • a spherical handle can be arranged above the first section.
  • the handle can also be cylindrical.
  • the handle can have a longitudinal axis.
  • the longitudinal axis of the handle can be identical to the longitudinal axis of the first section and/or to the longitudinal axis of the third section of the guide handle.
  • the handle can be rotatable about the longitudinal axis.
  • Such a handle makes the hand-held tillage implement user-friendly and efficient to use.
  • the soil cultivation device is so easy to handle and can be used flexibly and advantageously in narrow or crowded areas where precise guidance of the soil part is necessary.
  • the handle can be made of plastic, for example a thermoplastic.
  • the handle can also be made of metal.
  • the handle can include an anti-slip surface structure.
  • the handle can also comprise several materials or be made of a composite material.
  • the surface of the handle can be designed to be anti-slip.
  • the handle can be designed to be endlessly rotatable about the longitudinal axis.
  • the connection of the hand-held tillage implement can include two adjustable joints.
  • the joint axes of the two joints can lie essentially on the same plane and intersect.
  • the joint axes of the two joints can intersect at right angles. It is also possible that the joint axes of the two joints intersect at a different angle.
  • One Joint axis can be arranged in the processing direction of the soil cultivation device and a joint axis can be arranged at right angles to the processing direction of the soil cultivation device.
  • the base part By arranging the base part on the guide handle using the movable joint arrangement, it is possible to move the base part around obstacles, such as table legs, in the same way as a mop.
  • a joint arrangement can also be used to work on areas that are difficult to reach, such as niches and angles, with the base part.
  • the location of the joint axes on essentially one plane makes the joint particularly compact and yet movable.
  • the soil cultivation device can be designed to save space and a user can work with the soil cultivation device with very little effort and endurance.
  • the joint axes of the joints can be arranged at different levels.
  • the first joint axis can be arranged above or below the second joint axis essentially at right angles to the processing direction of the soil cultivation device.
  • the guide stem can be connected to the base part with the two joints, with one joint being arranged in a recess in the base part such that the joint axis of the joint intersects the body of the base part.
  • the other joint can then be arranged above it.
  • Such an arrangement makes the soil cultivation device particularly compact.
  • a supply hose can be passed through the upper joint and enter the base part next to the lower joint. In this way the supply hose becomes mechanical not used more than necessary.
  • the supply hose is particularly durable and the tillage tool requires little maintenance.
  • the first joint and the second joint can be joints of the same design.
  • the first joint and the second joint can also be differently designed joints.
  • the connection may include a ball joint.
  • the ball joint can be at least partially surrounded by an elastic element.
  • the ball joint can be brought into a rest position by means of the elastic element.
  • a ball joint moves equally in all directions and has essentially the same friction or resistance in all directions of movement.
  • a ball joint is particularly robust and insensitive to external mechanical influences such as shocks. If the ball joint is surrounded by an elastic element and can be brought into a rest position by this, a user is advantageously supported in arranging the base part. A user can then work with the soil cultivation device extremely comfortably and for a long time.
  • the ball of the ball joint and the socket of the ball joint can be made of the same material.
  • the ball of the ball joint and the joint socket of the ball joint can also be made of different materials.
  • the elastic element of the ball joint can be made of rubber or an elastomer or another elastic material.
  • the ball joint can also be surrounded by several elastic elements. It is possible that the ball joint is from a cuff made of plastic or rubber or another material. The cuff can be secured by a spring.
  • the fifth section of the hand-held tillage implement can be connected to the ground part by an elastic element.
  • the fifth section of the hand-held tillage implement can also be connected to the ground part by at least two elastic elements.
  • the elastic element can have a rest position and a longitudinal axis.
  • the elastic element can be curved from the rest position in a direction perpendicular to the longitudinal axis of the rest position.
  • the deformation properties of an elastic element can be predefined. In this way, the movement behavior of the base part on the elastic element can be advantageously influenced.
  • the movement behavior of the base part can be influenced by the interaction of the at least two elastic elements.
  • the soil cultivation device can thus be designed to be particularly advantageous for operation by a user.
  • the elastic elements can be designed so that they can be replaced by a user. New elastic elements can then be installed if the old elastic elements are defective or worn out. This means that the tillage implement can be maintained quickly and cheaply.
  • the elastic element can comprise one or more materials.
  • the elastic element can be made of rubber or an elastomer, for example.
  • the elastic element can also include a spring.
  • the elastic element can be designed as a hollow body or as a solid body.
  • the longitudinal axis of the elastic element can essentially be the longitudinal axis of the first section and/or the fifth section of the guide stem are equivalent to.
  • the longitudinal axis of the elastic element can be formed parallel to the first section and/or the third section of the guide stem.
  • a supply unit can be arranged on the guide handle of the hand-held tillage implement.
  • the supply unit can be arranged on the third section of the guide handle.
  • the supply unit can be releasably attached and/or arranged to be releasably attachable.
  • the supply unit can comprise an energy supply device and/or a cleaning liquid tank and/or a dirty water tank and/or a pump device and/or a suction device.
  • the supply unit creates a compact unit from which all consumables originate.
  • the center of gravity of the supply unit is arranged close to the longitudinal axis of the first section and/or fifth section of the guide handle. This results in an advantageous weight distribution and the soil cultivation device can be used extremely easily, flexibly and gently for the user.
  • a detachable arrangement of the supply unit makes it particularly easy to remove the supply unit from the handle in order to arrange the supply unit on a transport trolley or on a carrying device. Because the cleaning liquid tank and/or the energy supply device and/or the dirty water tank and/or the pumping device and/or the suction device is mounted centrally in the supply unit, the soil processing device can be designed to be extremely compact. In addition, maintenance and cleaning are particularly easy because many parts that need to be maintained or cleaned are concentrated in the supply unit. So the supply unit can with the Components described can be removed and the components can be changed, emptied or charged in a utility room, for example.
  • the supply unit can be designed to be attachable and detachable with a tool or without tools.
  • the energy supply device can be a battery, an accumulator or a network connection.
  • the energy supply device can be detachably integrated in the supply unit or can be designed as a cable in the event of a network connection.
  • the cleaning liquid tank and/or the dirty water tank can be detachably arranged in the supply unit.
  • the detachable arrangement of the energy supply device makes it possible for at least two energy supply devices, for example accumulators, to be provided for the operation of a soil cultivation device, with which the soil cultivation device is operated alternately. Then one energy supply device can be located in the supply device while the other energy supply device is being charged in a charging device. If the energy in the energy supply device, which is located in the supply device, runs low, the two energy supply devices can be exchanged quickly and easily. This means that the tillage implement can essentially be operated without any major work breaks. The progress and efficiency of the work are then essentially determined by the endurance of the user. The soil cultivation device is therefore not a limiting factor in daily work.
  • the supply unit of the hand-held tillage implement can be connected to the soil part via a supply line be.
  • the supply line can be arranged in the fifth section of the guide stem.
  • the base part of the soil cultivation device can advantageously be supplied with energy and media through the supply line. Due to the arrangement of the supply line in the fifth section of the guide handle, the supply line is at least partially surrounded by other components. This protects the supply line from external mechanical influences.
  • the supply line is arranged advantageously and is particularly low-maintenance and long-lasting.
  • the supply line can include one or more electrical conductors.
  • the supply line can also include one or more control lines.
  • the supply line can also include a fresh water line and/or a dirty water line.
  • the supply line can be rigid or flexible. Sections of the supply line can also be designed to be rigid, while other parts of the supply line are designed to be flexible. It is also conceivable that further electrical conductors and/or lines for media are formed in the supply line.
  • the supply line can be arranged at least partially in a joint of the fifth section.
  • the supply line can also be arranged completely in a joint of the fifth section.
  • the supply unit can have a dirty water defoaming device.
  • the dirty water defoaming device can be arranged in the dirty water tank of the supply unit.
  • the dirty water defoaming device can have several slats.
  • the dirty water defoaming device can be made of plastic or metal.
  • the dirty water defoaming device can also be made from other materials or from a combination of several materials or from a composite material.
  • the slats can be designed in such a way that the dirty water is placed between the slats and the dirty water is guided through the curvature of the slats.
  • the slats are advantageously opened downwards, towards the bottom of the dirty water tank. Water that is between the slats is thus transported by gravity from the slats to the bottom of the dirty water tank, while the dry air can flow through the slats into the exhaust duct.
  • the slats can be designed such that at the location where the dirty water hits the slats, the longitudinal axis of the slats is essentially parallel to the longitudinal axis of the dirty water jet.
  • the slats are advantageously designed to be slanted, so that the dirty water jet does not hit the slats with its full cross section, but rather has to travel a certain distance before the entire cross section of the dirty water jet hits the slats.
  • the bevel ensures that larger dirt particles are passed on better and thus prevents blockages.
  • the slats can have multiple curvatures.
  • the dirty water jet is divided into the spaces between the slats. Gravity causes the divided dirty water to become steel, which located between the slats, is conveyed to the bottom of the dirty water tank. Due to the arrangement of the dirty water defoaming device with the slats, the dirty water that enters the dirty water tank through the dirty water inflow drips and slides gently into the dirty water that is already in the dirty water tank. Without the dirty water defoaming device, the dirty water would enter the dirty water tank in a jet and significantly more foam would be produced. The dirty water defoaming device thus prevents or at least minimizes foam.
  • a support device can be formed on the guide handle of the hand-held tillage implement.
  • the support device can be formed in the third section of the guide handle.
  • the support device can have a working position and a standing position.
  • the support device can be lowered from the working position to the standing position.
  • the lowering movement can be linear.
  • the hand-held tillage implement can be advantageously supported by the support device.
  • the support device can be designed so that a user can lower the support device with a foot or hand without bending over. The support device can then be moved from the working position to the standing position to protect the user's back.
  • the support device can be made of plastic.
  • the support device can also be made of metal or other materials.
  • the support device can also comprise several materials.
  • the support device can include wheels or rollers, in particular two wheels or rollers, so that the hand-held soil cultivation device can be transported.
  • the wheels or rollers can be designed as solid bodies or as hollow bodies. It is also conceivable that the wheels are hollow and can be filled with air or another gas mixture or with a gas.
  • the support device can also include a locking device, so that the support device can be locked in the working position and/or the standing position. It is also possible that the support device can be brought into other positions and locked. It is also conceivable that the support device has a clamping device. In the essentially relaxed position of the clamping device, the support device is in the cleaning position. The support device can then be lowered into the standing position by a user. During the lowering process, the tensioning device is tensioned. In the standing position, the support device can then be locked with the clamping device tensioned. The support device can be moved from the standing position to the working position by releasing the locking device. As soon as the locking device has been released, the tensioning device relaxes and the support device simultaneously moves from the standing position to the working position.
  • the support device may be substantially lowerable while the first section and the third section of the guide post are in a vertical position until the rollers or wheels of the support device contact the ground. Then the tillage implement is supported in the standing position of the support device by the wheels/rollers of the support device and by the cleaning tools and the squeegee lip on the ground.
  • the vertical position of the support device and the first section and the third section of the guide handle results in a substantially vertical position of the soil cultivation device.
  • the soil cultivation device can be arranged in a very space-saving manner, for example in a utility room.
  • the soil cultivation device can be pivoted by a user in the essentially vertical supported position about the wheel axis/roller axis and can thus be brought into a driving position.
  • the driving position the tillage implement is supported by the wheels/rollers and held by the user.
  • the driving position the soil cultivation device can then be moved by a user from one application location of the soil cultivation device to another application location or from a storage location to an application location or from one application location to a storage location.
  • the support device means that a user does not have to carry the full weight of the tillage implement. Rather, a large part of the weight is carried by the wheels/rollers. The process is therefore an extremely gentle and efficient process for a user.
  • a hand-held soil cultivation device which includes a soil part.
  • the base part includes at least one tool for the soil cultivation and a motor to drive the tool.
  • the guide stem has a connection device for a supply hose.
  • the connection device can have a coupling device in the form of a rotary feedthrough for a supply hose.
