Definitions
- the present invention relates to a machine for treatment or maintenance of floors, comprising a motor carried by a frame, a circular tool tray suitable for being driven by this engine around a shaft of the chassis so that said tool can remain applied to the ground during operation, the remaining tray practically parallel to the ground and said chassis being rigidly connected to a drawbar carrying at its end upper an operating handle provided with at least one engine control lever.
- a machine of the type indicated at the beginning is, according to the invention, characterized in that the tool tray is connected by an elastic coupling to the chassis shaft, and that said elastic coupling includes a set radial blades whose ends are fixed with a part at one end of the chassis shaft and the other part, at the opposite end, on the tool tray via a flat disc.
- the operator can easily direct the machine on the ground, in the working position of the tool: to go forward in a straight line, weigh sideways on the operating handle, on the side for which the corresponding right half of the tray is moves backwards (for example on the right side if the tool turns clockwise), and on the opposite side, to know on the left side, to move backwards; to go to the right, it will suffice (in the same assumption of tool rotation clockwise) of weigh on the operating handle, i.e. weigh side for which the corresponding rear half of the tray moves to the left; to go to opposite to the left, it will just raise the operating handle, i.e. weighing from the side opposite, for which the corresponding front half of the tray moves to the right.
- the tray will be like this always under greater pressure on half of its circumference, but without the opposite half raises, precisely because the tool tray is connected elastically to the chassis shaft. The tool will therefore remain fully effective, even in changes of direction, since its entire surface will continue to be applied to the floor.
- the machine shown in Figure 1 has a chassis 1 carrying a pair of wheels at the rear steering 2 and a pair of load-bearing wheels transport of the machine in the inactive position, referenced in 3.
- the chassis 1 carries a motor 4, for example electric, connected for example by a belt 4a housed in a casing 5 (see also figure 2) to a shaft 6 of the frame.
- the machine can be maneuvered on the ground thanks to a drawbar 7 carrying a handle at its upper end maneuver 8 provided with at least one control lever motor 4 (not shown) and, where appropriate, a steering cylinder control lever, as will be seen later.
- FIG. 2 we have keyed to the shaft 6 a hub 9 housed in the chassis 1 via ball bearings 10 which hub is extended by a shouldered conical disc 11.
- a nut 12 On the threaded end 6a of the chassis shaft 6 are fixed by a nut 12 two washers 13 between which is tightened the central part of a number of blades elastic radial 14 on the outer ends which is fixed by a screw connection 15 and nuts 16, a flat disc 17 under which is hot glued under press a rubber crown 18 connected to the plate tool holder 19.
- the lower edge of the disc conical 11 is hot connected by another layer of rubber 20 at the edge of the upper surface of the disc flat 17.
- Figures 5 and 6 show another variant, according to which one uses between the shaft 6 of the chassis 1 and the tool holder plate 19 an elastic coupling to several plates 25 linked in pairs by washers perforated elastic 26 whose holes 27 receive studs 28 of these plates, this coupling being used in the embodiment of Figure 7 with the plate lower 25i fixed to the plate 19 and the upper plate 25s wedged on a rotating part 30 secured to the shaft 6.
- two of the four cylinders for example electric, mounted at 90 ° one on the other between chassis 1 and a rigid disc upper 11 with interposition of pressure rollers 31, and which allow, from another joystick of the handle 8, to control the multidirectional tilt of chassis 1 relative to the ground, without energy expenditure physical on the part of the operator.
- this command tilt could also be provided by any other means such as a linkage, rods, levers or others, in a manner known per se.
- the invention will in any case allow a clear ergonomic improvement as well as an improvement of the performance of such floor care machines and a significant increase in their comfort of use.
