Definitions

  • the invention relates to a small vehicle, in particular a wheelchair, with a modular structure.
  • Wheelchairs including those that can be driven by a motor, usually have a frame in which a seat is integrated and on which two drivable wheels and two freely pivotable or optionally motor-steered wheels are directly linked.
  • the drivable wheels can be driven manually via hand rims or by motor.
  • Such wheelchairs are often provided with a folding mechanism which enables the wheelchair frame to be folded up.
  • a wheelchair is known for example from EP 0 790 049 A2.
  • Wheelchairs of the type explained above are particularly suitable for a so-called outdoor operation, i.e. Operation outside closed rooms and especially on uneven paths, for example field or forest paths, is unsuitable.
  • the frame construction described has only a relatively low stability.
  • the direct linkage of the wheels to a tubular frame only allows insufficient suspension for uneven paths, which is usually provided exclusively by appropriate pneumatic tires.
  • the technical problem on which the invention is based is to provide a small vehicle, in particular a wheelchair, which has a stability which is also suitable for outdoor operation and a driving behavior suitable for outdoor operation and at the same time enables it to be dismantled, which makes it possible to transport it in the usual way Passenger cars allowed.
  • the small vehicle according to the invention has a modular structure with a base element, with at least one pivotable wheel which can be detachably attached to the base element by means of a quick-release device, with at least one drive wheel which can be detachably attached to the base element by means of a quick-release device, and with a seat device, which can be releasably attached to the base element by means of a quick-release device.
  • the base element has a base body, on which four links are spring-mounted for fastening the wheels.
  • the quick release devices between the base element and the wheels are each arranged between the handlebars and the wheels.
  • the small vehicle according to the invention has a modular structure with a basic element which not only disassembles the wheels, but also the seat device from the base element by means of quick release. This enables particularly space-saving transport with high stability and strength.
  • the base body is preferably self-supporting and assumes the load-bearing function of the chassis.
  • the four links preferably run within a common plane, so that the basic element with the base body and the four articulated links assumes a flat shape.
  • the basic element preferably has its main dimensions within a plane, while the dimensions perpendicular to this plane, on the other hand, are significantly smaller.
  • the small vehicle is therefore comparable in its external dimensions to a collapsed wheelchair of the type described at the outset and in this respect is even superior in this respect, while at the same time having a significantly higher stability and strength with a lower weight.
  • the smallest possible cuboid with the side lengths a, b and c, into which the basic element with the base body and the four articulated handlebars fits without wheels, can, for example, have a side length c that is less than half the side lengths a and b.
  • the side lengths a and b correspond to the main dimensions and the side length c corresponds to the depth of the flat cuboid.
  • the drive wheels preferably have a hub motor. This eliminates the need for a drive train from the chassis to the drive wheels.
  • the torque is generated in the hub motor itself and the fixed part of the hub motor only has to be supported on the corresponding handlebar by means of a suitable device in order to ensure propulsion.
  • Corresponding electric motors are particularly suitable for driving such a small vehicle.
  • the accumulators required for the power supply can be fastened to the base element, in particular to the base body, preferably also by corresponding ones Quick-release devices that allow the batteries to be changed quickly.
  • Connection points for accumulators can be provided on opposite sides of the base body.
  • several connection points can be provided for optional operation with one or more accumulators, which can be fastened centrally to the vehicle axis when operated with an accumulator and which can be fastened symmetrically to the vehicle axis when operated with several accumulators.
  • the seat device of the small vehicle preferably has a seat, a seat back and a footrest and two armrests and forms a complete unit.
  • This unit can, preferably also by means of a quick-release device, be attached to and detached from the base element, in particular at the base body.
  • the seat device can be designed to be foldable. Due to the modular design of the small vehicle, a particularly ergonomically designed seat, for example a specially designed seat shell that may be specially produced for a patient, can also be easily mounted on the base element. Seat shells can also be used for the severely disabled. This also makes it easy to retrofit or modify the wheelchair, particularly with regard to a special seat shell.
  • the interface between the seat and the base body is preferably designed so that an adaptation of a special seat is easily possible. It is possible, for example, for special seats to be provided by specialist dealers, for example a medical supply store, or to be produced specifically for a specific application, and to be connected to a wheelchair according to the invention which is produced in large numbers and which is supplied without a seat device.
  • the seat device can also be arranged rotatably so that when the seat is rotated through 180 °, a vehicle with rear-wheel drive becomes a vehicle with front-wheel drive.
  • the handlebars for receiving the freely swiveling wheels are preferably designed as spring-mounted double links. This makes it possible to ensure that the caster of the freely pivotable wheels remains essentially constant over the entire spring travel, in particular when the freely pivotable wheels are articulated on the handlebars by means of a thru-axle running vertically to the ground. If the suspension travel is limited, the front links can also be designed as single links.
  • the handlebars provided for receiving the drive wheels are preferably designed as trailing arms which are supported on the base body via a spring / damper unit.
  • a small vehicle designed as a wheelchair of the type described above has excellent stability and enables the wheels to be spring-loaded, which permits operation even on uneven paths.
  • the structure of this wheelchair allows it to be disassembled into individual assemblies, which enables the wheelchair to be transported in the trunk of a commercially available car.
  • the basic element for example the basic body with the four handlebars, this assembly being a flat component that is easy to carry.
  • the individual wheels and the accumulators can also be easily stowed away and the seat device can also be brought into a space-saving flat shape by means of a corresponding folding mechanism.
  • the base body can have interfaces for electrical lines at the fastening points of the drive wheels and / or the seat device and / or the accumulators.
  • a control panel can be provided on an armrest of the seat device.
  • accumulators that are attached to the base body, all that then has to be provided is a current transmission to the hub motors.
  • the accumulators are also housed in the wheel hubs of the drive wheels and a wireless signal transmission of the control commands is provided, the need for electrical lines between the chassis and the wheels is completely eliminated.
  • a base body 10 is provided in the form of an extruded profile 11 made of an aluminum alloy.
  • the extruded profile 11 is closed at its two longitudinal ends by means of appropriately screwed end plates 12.
  • Stiffening elements (not shown) or other assemblies, for example switching devices, etc. (not shown) can be arranged in the essentially hollow interior of the base body 10.
  • a receiving device 14 is provided which serves for the easily releasable fastening of a seat device 50 by means of a quick-release device, not shown in any more detail.
  • the seat device 50 has frame profiles which, together with a covering or upholstery, not shown, result in a seat 51, a seat back 52, a footrest 53 and a strut 54 for fastening a control panel 60. It is understood that armrests (not shown) can be provided on both sides.
  • the seat device for example a seat surface and a backrest, optionally with corresponding side parts, as a self-supporting structure with corresponding connecting elements to the base body or a corresponding seat frame.
  • the seat device is provided with a folding mechanism which allows the seat device 50 detached from the base body 10 to be folded up in such a way that it results in an easily transportable, essentially flat element.
  • the base body 10 On the base body 10, two front links 20 and two rear links 30 are articulated, in each case on the left and right side, as seen in the direction of travel.
  • the rear link 30 are designed as trailing arms, which are supported on the base body 10 via a spring / damper arrangement 31.
  • the front links 20 are designed as double links, which are coupled to one another via a spring / damper mechanism (not shown) arranged in the interior of the base body 10.
  • the base body 10 forms a base element together with the articulated links 20, 30.
  • Two drive wheels 35 are articulated to the rear links 30 by means of horizontally running plug-in axles 36 and quick release devices (not shown in more detail).
  • Two freely pivotable front wheels 25 are articulated on the front links 20 by means of vertically arranged plug-in axles 26 and also quick-release devices (not shown).
  • the position of the axis of rotation 27 of the front wheel 25 is offset relative to the position of the thru axle 26 in the installed state, so that there is a caster that always aligns the front wheels 25 in the direction of travel when driving straight ahead.
  • the wheelchair is controlled by a separate actuation of the two driven rear wheels 35, the drive preferably being effected via hub motors, not shown, which are designed as electric motors, and the steering commands being entered via the control panel 60.
  • the front link 20, designed as a double link, is designed such that the caster of the front wheel 25 remains essentially constant over the entire available travel.
  • One or more accumulators 70 can be attached to the base body 10 by means of quick-release devices.
  • the quick-release devices for fastening the batteries 70 have interfaces for electrical lines which provide an electrical connection of the batteries 70 to the hub motors.
  • a protective device in the form of a protective bracket 80 can be attached to the base body 10, preferably in a removable manner.
  • a climbing aid 28 is provided on the front wheels 25.
  • the climbing aid 28 is designed in pairs per front wheel 25 and is spring-loaded on both sides of each front wheel 25 so that it assumes the position shown in FIG. 6 in the normal operating state.
  • the climbing aid 28 can be pivoted about its pivot axis 29 by a certain path in the direction of rotation of the wheel indicated by the arrow A in FIGS. 6 and 7.
  • the climbing aid 28 When the wheelchair approaches the front edge 90 of a curb 90, the climbing aid 28 is initially in the uppermost pivot position, which is predetermined by the spring force. As soon as the climbing aid 28 comes into contact with the curb 90, the climbing aid 28 pivots in the direction of rotation of the front wheel 25 as a result of the propulsive force provided by the drive wheels. This raises the front wheel 25 until it comes into contact with the curb in a suitable position that it can overcome the step given by the curb 90 with further forward movement.
  • the direct articulation of the climbing aids 28 on the freely pivotable front wheels 25 ensures that the climbing aids 28 are always in a suitable orientation to an obstacle, in particular when inclined to one Curb or another step is approached.
  • the climbing aids can also be articulated directly on the base body.
  • the seat device 50, the accumulators 70, the rear wheels 35 and the front wheels 25 can be removed by means of simple quick-release fasteners, the seat device 50 being able to be correspondingly folded or folded after removal.
  • the fact that it can be dismantled also ensures that the individual components have a relatively low weight, so that the components can be easily stowed away.
  • the provision of quick-release fasteners means that the wheelchair can be dismantled easily, even by technically unskilled people, without any tools.
  • the wheelchair is easy to dismantle, due to its construction according to the invention, it is suitable for also being used outdoors. It combines the comfort of four spring-loaded wheels and the stability required for outdoor use with the lightness and portability of an ordinary indoor wheelchair.
