Abstract
A plurality of modular-construction hand-operated motorized devices, including a lawn mower, a verticutting implement, a sweeping device, and a device for loosening the soil or taking in and blowing out leaves are disclosed. Each device includes a limited number of differently designed and dimensioned main and additional modules which provide for a wide range of individually adapted types of devices to be constructed.
Claims12
A modular-construction hand-operated motorized lawn mower, comprising
- a main module comprising a rigid frame with a motor bearing, axle bearings and an articulated guide bar, said frame having two longitudinal supports which slope up from front to rear, two rear supports which slope steeply in the downward direction from the rear end of the longitudinal supports, and a rear connecting tube which connects to a plurality of connecting locations of the longitudinal and rear supports, the motor bearing being suspended on the longitudinal supports;
- and
- additional modules which can be fitted and removed individually, wherein at least the following additional modules can be added on to the rigid frame:
- a running gear which can be connected to the rigid frame by means of the axle bearings;
- a motor unit as drive module;
- a cutting unit;
- a hood with an air-stream guide as a channeling system;
- and wherein the above-mentioned modules can be combined with one another in an exchangeable manner in different predetermined dimensions and in different constructions.
