Definitions

  • the invention relates to a universal nozzle, designed for use in connection with the hitherto known vacuum cleaners, with or without washing devices, to carpet brushing equipment or other floor cleaning machinery, to clean floors covered with different materials, such as carpets, pre-mixed carpeting and other textiles and to floors covered with solid materials, such as wood, parquet, plastic materials, tiles or other ordinary used floor materials.
  • a nozzle especially useable to remove hair originating from humans, dogs and cats, and thread, lint and the like from floors, carpets and other textiles, with or without the use of washing devices.
  • the nozzle should have excellent wearing qualities and be gentle to the floor surface.
  • the nozzle should be self-cleaning to the greatest possible extent.
  • the nozzle should also be usable for the cleaning of other kinds of textiles, furnitures, car seats, cushions etc.
  • the nozzles known until now for vacuum cleaners and carpet brushing equipment and the like are characteristic thereby, they are moved forward and backward along the surface. Even if the nozzle is equipped with different kinds of devices, fitted to that side facing against the floor surface, the forward and backward going movement along the floor surface will not be able to loosen and pick up hair and fibers, to such an extent that they can be removed efficiently by a vacuum cleaner.
  • Some nozzles are provided with backward directed teeth of different materials, gripping the nap of the carpet, to remove hair and fibers, etc. Consequently, the nozzle is hard to move and is causing heavy wear on the surface, and hair and fibers are catched in the teeth, whereupon these have to be cleaned manually.
  • nozzles are provided with textile pads, but these are by experience worn-out rapidly, for which reason they loose their ability to catch hair, etc. Likewise, hair and lints get stuck in the pad.
  • Other known nozzles are using one or more rails of different profiles and methods of suspension, acting by drawing the sharp edge of the rail along the surface of the floor, which consequently is causing heavy wear of the carpet.
  • the up till now known nozzles are not designed to clean all kinds of flooring, or to clean with water or detergents.
  • the known designs are not comprising a nozzle, which rapidly can be converted to perform cleaning jobs of different kinds, for which reason the user must be in possession of different types of nozzles.
  • the use of the known mechanical or motordriven rotatory brushes is expensive, and does not solve the problems satisfactorily, as hair and fibers are twisted around the brushes , which are difficult to clean.
  • Danish patent No. 124919 therefore, is not providing a device, which include the in the aforementioned described qualities.
  • Document DE-A-2835781 discloses a nozzle for vacuum cleaners comprising a cylindrical roller, wherein the roller can be blocked against rotation.
  • a construction of a nozzle is provided, which is of the in the introductory part of claim 1 described character, and which has the qualities described in the introduction, included in one and the same nozzle, which is described in the following.
  • the nozzle includes a housing and a pipe socket and is provided with cylindrical rollers, with horizontal axis of rotation and transversely positioned in relation to the moving direction of the machine and characterized in that each roller is containing an axle with two or more free wheeling bearings fitted in a tube covered with outside facings, which can be of varied materials.
  • the free wheeling bearings are so constructed, that the roller at movement along the floor in a certain direction, freely can rotate around its own axis, but the roller is blocked, when it is moved in the opposite direction. When the roller is moved along the floor surface in blocked position, hair, fibers, etc.
  • the in the invention used rollers can be covered with outside facing of various kinds, adapted to the actual cleaning task.
  • rollers with a plane - or a nearly plane - rubber surface can be used, and thereby, both efficiently and gently, remove hair, thread and the like.
  • the vacuum cleaner used is of the type, after which water or detergent through a jet is sprayed on the carpet surface, the said rubber rollers are suitable to wipe the water against the extractor duct, for efficient extraction.
  • Another roller can be covered with an outside facing, designed as an cylindrical brush roller or be covered with bristle like materials, which partly is asissting to remove hair etc. and partly gives the carpet pile a slight brushing effect, which is improving the vacuum cleaning effect.
  • the same brush roller can also be used for dry vacuum cleaning on solid flooring. Mainly at floor washing, the brush roller is working as a fixed brush in the blocked position - similar to a scrubbing-brush - while the rubber roller is working like a rubber scraper, when the nozzle is moved in the direction, where the roller is blocked.
  • Other type of roller facings can also be considered, adapted for the job.
  • the in the nozzle in accordance with the invention, mounted rollers can be suspended in a combined suspension and activation unit, making it possible, easily to activate that or those rollers , the user wants to apply after demand.
  • the user can select to activate the brush roller alone, the rubber roller alone, both rollers at the same time or none of the rollers.
  • the activation of the rollers are guided by a hand or foot operated activation grip on the upper side of the nozzle.
  • the suspension with rollers is pressed against the surface of possibly adjustable springs or by its own weight.
  • the suspension and activation system used in the nozzle can be extended by demand to include several adjustable functions, for instance when manufacturing nozzles for professional use. Likewise, a more simple design also can be considered.
  • the rollers used in the nozzle, according to the invention are provided with scraping plates, so designed and so suspended, that the surfaces of the rollers are being scraped by the plates, thereby hair and foreign materials, which are sticking to those, are scraped off and extracted, when the rollers rotate.
  • the plate, which is cleaning the brush roller can be likely designed as a comb, where the teeth are intruding between the bristles of the brush rollers.
  • hair, etc. are picked up by the brushes, when the roller is moved along the surface in the blocked position, and catched by the comb and extracted, when the roller is revolving.
  • the plate, cleaning the plain rubber roller can be designed as a straight, rectangular plate of suitable materials, for example steel or plast, possibly provided with a hard-wearing edge against the roller.
  • the scraping plate can be suspended in pivot pins, and can be pressed against the rollers, either by means of springs or by own weight.
  • the rectangular plate which in accordance with the invention, is cleaning the plain rubber roller, prevents the air stream pass by the upper surface of the rubber roller, when the plate is designed air tight or nearly air tight.
  • the suction of the nozzle is concentrated to the space between the roller and the underlay. If the air stream is blocked to such a degree, that the vacuum power is reduced, the plate which is preventing the air stream to pass the top of the roller, opens due to the difference in the pressure between the vacuum side and the pressure side.
  • the weight of the plate or the tension of the spring load By adjusting the weight of the plate or the tension of the spring load, the time of opening and closing can be regulated after need. It is of greatest importance to establish the highest possible vacuum in the mentioned space area, especially when suck in water. When the rubber roller is out of function by lifted up from the floor surface, free suction below the roller is established.
  • the said nozzle can be designed in different ways some of which are described in the following, referring to the enclosed drawing, Figures 1, 2, 3, 4, and 5.
  • Fig.1 is shown a cross section of a cylindrical roller.
  • the roller is carried of an axle 1, which can be fastened in the nozzle for a vacuum cleaner, a brushing machine or to a similar floor cleaning machine, and be of a suitable length in relation to the nozzle.
  • axle 1 On the axle 1 is fitted two or more free wheeling bearings 2 of a known construction, which allows rotation in one direction only, fitted in a tube 3, covered with suitable facing on the outer surface 4.
  • the free wheeling bearings allow the roller to revolve, indicated by the arrow c, along the surface 5.
  • the surface of the roller can be of different suitable materials, just as the structure of the surface can be of different nature.
  • Fig.2 is shown a roller designed as described under Fig.1, but with an outside facing of brushes 6.
  • the stiffness and the shape of the bristles can be made in accordance with the cleaning task.
  • Fig.3 is in cross section shown the construction of an activation handle device, which, in accordance with the invention, is activating the said suspension and activation device.
  • the activation handle 7 has an approximate triangular cross section and is of a suitable length, and can turn around the axis 8.
  • the lower edge of the handle 7 is cut across to allow a rolling movement, shown by the arrow j, along the upper surface of the nozzle 11.
  • the elevating arm 9, carrying the roller suspension in the axel 10 is lifting or lowering the suspension a similar distance f, which is equal to the difference between the distances d and e, obtained when the activation handle 7 is turned.
  • Fig.5 is in cross section shown a practical construction as an example, using two of the in the invention said cylindrical rollers, as shown and described in Fig.1 and Fig.2.
  • the one roller, Fig.2 is shown as a cylindrical brush roller, fastened at the axle 1 in the arms 16.
  • the other roller, Fig.1 is shown with a cylindrical cover of rubber materials, fastened at the axle 1 in the other end of the arms 16.
  • the arms 16 are turnable in an arc of circle round the pivot pins 17, so the rollers, Fig.1 and Fig.2, can be lifted or lowered as required, as indicated by the arrows h.
  • the arms 16 are raised or lowered by the vertical bars 9, fastened in the lower end of the pivot pins 10 in the arms 16, and in the upper end at the pivot pins 8 in the activating handle 7.
  • the rollers Fig.1 and Fig.2 are pressed down against the surface 5 by the springs 18.
  • the pressure of the rollers, Fig.1 and Fig.2, against the surface 5, can be regulated. If the rubber roller, Fig.1 is to be uncoupled, it can be lifted by turning the foot or hand operated activation handle 7 in the direction, as indicated by the arrow j.
  • the rollers Fig.1 and Fig.2 can revolve freely around there own axis, as indicated by the arrow g.
  • the nozzle 14 is moved backwards as indicated by the arrow b, the free wheeling bearings in the rollers, Fig.1 and Fig.2, are blocking the rollers.
  • the direction depending scraping effect is obtained, as intended by the invention.
  • the brush roller, Fig.2 is provided with a plate made as a plane comb-shaped plate 12, as shown in Fig.4, suspended in the point 21 so the teeth of the comb are intruding the bristles at the brush roller, Fig.2.
  • the brush roller, Fig.2 is withdrawing hair and foreign materials.
  • the brush roller Fig.2 is revolving. Hair and foreign materials, caught by the brushes, are scraped off and evacuated. Hair thread and the like are thereby not winded around the roller.
  • the rubber roller, Fig.1 is provided with a plate made as a rectangular plate 13, Fig.4, and suspended in the point 22 in such a way, that it fits tightly against the roller, Fig.1, by means of the spring 20 and is turnable, as indicated by the arrow i.
  • the roller, Fig.1 is rotating, as indicated by the arrow g, whereby, hair and foreign materials including possible water, are scraped off the roller, Fig.1, by the beam 13, at which the roller becomes self cleaning.
  • the rectangular plate 13, Fig.4, can be so constructed so it fully or partly, is preventing the air stream to pass the upper side of the roller, Fig.1.
  • the necessary vacuum, sufficient to open the air passage along the upper side of the roller, Fig.1, by turning the plate 13 as indicated at the arrow i, can be regulated by means of the tension of the spring 20 or by the weight of the plate 13.
