BRIEF SUMMARY
TECHNICAL FIELD OF THE INVENTION
In a first broad aspect the present invention relates to a mobile unit for applying fluids on large surfaces. In a closer aspect the invention relates to a unit for painting in particular floor surfaces.
BACKGROUND OF THE INVENTION
In the paintwork technique it occurs that large coating surfaces are re-painted at short intervals. This is for instance the case in studio premises for filming purposes. Film-directors in charge sometimes desire a certain color on the floor of the room and sometimes quite another color; all depending on the character of the current film production. This means that the service staff which are responsible for the indoor picture may have to repaint the floor of the room at short intervals, since repainting has to be carried out not only between the production of different movies, but also between different sequences in one and the same movie. As the floor surfaces of the studio premises can amount to many hundreds of square meters or more, it is realized that the painting work is extremely burdensome when it has to be carried out manually as hitherto customary, either by means of brushes/rollers or alternatively by means of spray nozzles held by hand.
OBJECTS AND FEATURES OF THE INVENTION
In its closer aspect the present invention aims at providing a mobile painting unit by means of which the painting of large surfaces, such as the floor surfaces of a studio premise, can be facilitated and rendered more effective. Accordingly, a primary object of the invention is to provide a unit which is capable of applying paint swiftly and efficiently on large surfaces without giving rise to environmental inconveniences in the surroundings of the unit. Thus, the unit according to the invention shall make it possible to apply paint of e.g. an indoor coating surface without giving rise to troublesome air pollutions in the environment. A further object of the invention is to provide a unit which can be driven along the coating surface in question in a manner which is comfortable and ergonomically appropriate for the operator. In its broader aspect the invention also aims at providing a unit for applying other arbitrary fluids than paint on a selected surface irrespective of whether this is a floor surface or another substrate.
BRIEF DESCRIPTION OF THE ATTACHED DRAWINGS IN THE DRAWINGS:
FIG. 1 is a perspective view of a first unit according to the invention, integrated with a motor-driven vehicle, and
FIG. 2 a partly cut schematic perspective view of a second, developed embodiment of a unit according to the invention, likewise integrated with a motor-driven vehicle.
DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS
In FIG. 1 a fluid application unit according to the invention is generally designated 1. Is accordance with a preferred embodiment of the invention this unit is built up on a wheeled and motor-driven vehicle generally designated 2. In the example the vehicle is a three-wheeler including a driver's seat 3, a front-mounted steering wheel 4 for controlling the single front wheel 5' of the vehicle (the two rear wheels of the vehicle are designated 5") as well as an electric motor which is enclosed in a box under the driver's seat and by means of which the vehicle can be driven in a conventional manner. The necessary power supply may be provided through a swivelled cable (not shown) which is supported by a post 6 mounted behind the driver's seat. It is, however, also possible to use batteries for the power supply of the motor.
The unit 1 is preferably mounted at the rear end of the vehicle 2. The externally visible components included in the unit 1 of the embodiment according to FIG. 1 consist of a casing generally designated 7, which comprises a substantially horizontal plate 8 forming a frame as well as a shielding or border generally designated 9 which projects downwardly from said frame plate. On top of the frame plate 8 a housing 10 is mounted in the interior of which an air evacuating device in the form of a suction fan is arranged. Visible in
