Definitions

  • the hand-held motor lawn mowers currently offered for home garden operation have a self-supporting chassis which, as a central element, absorbs all operating forces and to which all attachments are attached.
  • These lawn mowers are supplied by the manufacturer in a few predetermined variations, which differ essentially only in terms of their cutting width and their drive.
  • the individual series-produced mower types are approximately adapted to the needs and wishes of consumers and equipped with either an internal combustion engine or an electric motor with mains connection or battery operation, the power of the motors naturally having to be adapted to the cutting width. After the customer had bought a lawn mower of a certain type, changes, particularly in terms of performance and cutting width, were no longer possible.
  • a lawnmower In contrast to the lawnmowers mentioned above, in which a rigid chassis is provided which supports the wheels and carries the attachments rigidly attached thereto, a lawnmower has become known from US Pat. No. 3,537,720. in which two wheel carrier frames are mounted with limited movement with each other and with the add-on parts. Two side frame parts supporting the wheels are connected to a transverse front wall by means of joint pieces, and the cover for the mower deck, which carries the motor, is connected to the side frame parts by two further joint pieces. This is to ensure that all wheels maintain their contact with the ground on uneven terrain. This is to keep the bottom gap small to. prevent stones or the like thrown from the cutting blades from escaping and causing injuries.
  • the invention has for its object to enlarge the range of lawn mower types offered to the buyer and thereby to make it possible to offer the customer individually tailored lawn mower types without the need to create their own production for each type, but the Selling price can be kept in a reasonable range.
  • the rigid frame can be designed in a relatively simple manner in such a way that it can withstand all loads without damage even in exceptional operating conditions records
  • the other parts especially the cladding and the parts of the grass and air control system, can be easily, for example made of plastic, but also made of thin aluminum or steel sheet, inexpensive to manufacture or the material can be adapted to special customer requests.
  • the frame itself can be welded as a rigid unit, or it can be screwed together, and there is also the possibility of designing the frame itself in modular form in order to enable optimal adaptation to lawnmowers of different sizes and / or performance.
  • a two-axle undercarriage with four wheels is generally considered as the undercarriage, which are arranged in a manner known per se such that they can be adjusted in height together via an adjusting lever in order to be able to adjust the working height.
  • a roller can also be arranged in an appropriately designed module.
  • the invention creates the possibility of arranging other tool assemblies instead of the mower for lawn mowing, for example scarifying knives or a device for loosening the soil or also a device for sweeping up or for sucking in and blowing out leaves, for example.
  • FIG. 1 is a perspective view of a modular lawnmower in accordance with the present invention
  • Fig. 2 shows the lawnmower of Figure 1 in a partially assembled state.
  • Fig. 3 is a perspective view of individual modules that make up the lawn mower of Fig. 1;
  • Fig. 4 is a perspective view of a modular rigid frame
  • FIG. 5 is a perspective view of the frame according to FIG. 4 with the motor supports inserted;
  • FIG. 6 is a perspective view of a modular system with four wheels, axles and connecting rod for working height adjustment
  • FIG. 7 is a schematic illustration of lawn mower modules which can be assembled into a lawn mower in different ways.
  • a double delta frame 10 is provided as the load-bearing element, which consists of two side members 10.1 rising obliquely from the front to the rear, two rear members 10.2 rigidly connected therewith, and a rear connecting pipe 10.3.
  • This frame 10 can be used as a basic element for all different lawn mower types; however, it should also be reserved for the invention to provide different frame dimensions, the frame itself being able to be designed in modules.
  • a motor support bearing 12 in the form of curved, curved support plates is suspended from the longitudinal beams 10.1.
  • pivot bearings 14 are arranged for the guide bracket 16, about which the guide bracket 16 can be pivoted and fixed in a known manner in any angular position.
  • the free ends of the longitudinal members and rear members are provided with axle bearings 18.1 and 18.2.
  • One 10 of the side members also carries a locking mechanism 20 for cutting height adjustment.
  • FIG. 6 shows the travel and height adjustment system 22, which is designed as a module.
  • the undercarriage has four running wheels 24, the stub axles of which are connected in pairs to one axle 28.1, 28.2 each via radially extending arms 26. These axes are rotatably supported in the axle bearings 18.1, 18.2. By rotating the axle bearing rod 28.1, 28.2 in their bearings 18.1,
  • the cutting height can be adjusted.
  • a simultaneous adjustment of the cutting height of the front wheels and rear wheels is effected by a steering mechanism 30, which can be transferred into operative connection with the locking mechanism 20.
  • a motor unit can be screwed onto the motor support bearing 12.
  • This motor unit can be designed as an internal combustion engine 32.1, as a battery motor unit 32.2 or as an electric motor 32.3.
  • a cover 34 is attached to the frame 10.
  • a front apron 36 designed as a module and fixable on the frame or connected to the cover 34 covers the front wheel suspension in the assembled state.
  • the cover 34 as can be seen in particular from FIG. 3, is equipped with air guiding or grass guiding channels 40.
  • the grass catcher 42 is designed as a further module, which can be suspended in the rear area by means of its front hook 44 and projects into the guide channel 40 with a guide plate 48 when the catcher 42 is suspended on the frame 10.
  • the catch container is provided with a hinged flap 46.
  • the mowing unit can be designed as a knife rotating in a horizontal plane, which is fixedly connected to the motor output shaft or can be coupled as a module to the latter.
  • This mowing unit can in turn be supported in a manner known per se by a bearing which is connected to the motor support bearing 12.
  • other tool assemblies can also be fixed to the motor support bearing 12 in combination with their drive motor or as a module with any drive motor.
  • work units can be, for example, a scarifier, a sweeper, a blower or another device.
