Definitions

  • the subject of the present invention is concerned with a painting roller, which is self-supplied without the aid of an electric motor or compressor or other sources of energy
  • GB-A-1 508 260 discloses a self-supplied paint roller provided with a rotating tubular support secured, to the fixed tubular support, at the free end of the drum of the paint roller, via an end cover plate and a screw.
  • a purpose of the present invention is consequently to overcome the drawbacks inherent in self-supplied rollers of a known type.
  • FIGS 1-7 and 13-19 show a painting roller which is referred to, as a whole, with the reference number 1 and comprises:
  • the tubular support 6 and the bushing 7 are screwed together by means of the female threaded surface 8 and male threaded surface 9, and are mounted on the fixed tubular support 6A ( Figures 3 , 5 ) or, more in general, on a pin-like support 6A.
  • Figure 4 is the front view of the threaded end 9 of the support 6. Said end has a plurality of radial projections 10 and a plurality of notches 12.
  • annular groove 11 Made on the fixed tubular support 6A is an annular groove 11 (see Figure 5 ).
  • the male threaded end 9 is screwed into the female threaded seat 8, the notches are reduced and the side projections 10 are clinched and engaged in the annular groove 11, fixing the rotating support 6 on the fixed support 6A in such a way that the former (together with the roller 5) can rotate with respect to the latter, without sliding out axially.
  • the rotating support 6 is provided, at its free end, with a gripping area 44, with which the user can disassemble and reassemble the rotating support 6 with his hands, without any need for tools.
  • the roller 5 may be covered by an appropriate absorbent material 19.
  • the paint is enclosed in the chamber 15 and is made to come out therefrom, for supplying and impregnating the absorbent material 19, via one or more holes 14 (see Figure 5 ) which communicate with the chamber 15 itself, and then through a plurality of small holes (not shown) made on the roller 5.
  • the fixed support 6A (see Figure 5 ) has a seat 16b for the seal gasket 17, which communicates with a chamber 18.
  • the paint is fed to the chamber 15 (see Figure 3 ) by means of a supply tube 22 (see Figure 1 ) via suction with a pump, designated, as a whole, by the reference number 21.
  • the supply tube 22 is fixed by means of special clamps 23 to the goose-neck support 4 ( Figures 13 , 20 ). At the intake end, the tube 22 is immersed in the diluted paint in any suitable container, and blocked with a purposely provided clamp.
  • a filter 20 (see Figures 1, 2 ) with the function of withholding possible impurities that could jeopardize the operation of the pump 21.
  • the filter 20 can be equipped with a valve 20b (see Figure 2 ) to prevent any backflow, from above downwards, of the paint within the supply tube 22.
  • said non-return valve is a membrane valve similar to the valves 26, 27 described hereinafter; said type of valve in fact is able to ensure a better seal also in the presence of high pressures of backflow of the liquid.
  • the pump 21 of Figure 18 comprises a hollow piston 33 in a position corresponding to its point of delivery.
  • the pump 21 is provided with at least one membrane valve, for intake 27 or delivery 26.
  • the pump 21 comprises two membrane valves 26, 27, each comprising a body made of elastic material, or in any case deformable material, substantially shaped like an umbrella or cup, and provided underneath with a fixing appendix 28 and a fixing appendix 29, respectively (see Figure 18 ).
  • the umbrella-shaped valve 27, which functions as intake valve, is fixed, via the respective bottom appendix 29, to the outer casing of the pump 21, whilst the umbrella-shaped valve 26, which functions as delivery valve, is fixed, via the respective bottom appendix 28, within the hollow piston 33, so as to move fixedly therewith.
  • valve 27 is fixed in the seat 30 of the annular support 31 (see Figures 18, 19 ), and the latter is screwed or restrained, via convenient assembly, on the edge 31B (see Figure 18 ) of the hollow piston 33. Also fixed on the annular support 31 is the gasket with annular lip 25.
  • the membrane valves in particular the umbrella-shaped valves, ensure a higher degree of tightness than do other types of valves - for example, ball valves - and thus enable the required suction pressures for intake.
  • the present applicant has succeeded in building pumps 21 with a self-priming height greater than 6-8 metres.
  • the piston pump 21 can moreover be provided with a tubular sleeve substantially shaped like a bellows 24, or else other membrane or casing of an appropriate shape, having the function of preventing the liquid pumped from coming into contact with the hollow piston 33 and the gasket with annular lip 25, so as to eliminate substantially the problem of abrasion due to the sediments contained in the paint.
  • cam-actuation system 34, 35 Another advantageous characteristic of the present example of embodiment (see Figures 1-8 and 13-19 ) of self-supplied painting roller is the cam-actuation system 34, 35, which enables actuation the pump 21 by rolling the roller 5.
  • the furrow 36 and its raised edges 35 actuate the pin 37, which, via the lever 39 (see Figures 13 , 14, 16 ), actuates the hollow piston 33 of the pump 21.
  • the lever 39 is fixed to the hollow piston 33 by means of the pins 42 (see Figures 17 and 18 ), which are engaged in the eyelet 39B (see Figure 13 ).
  • the lever 39 moreover pivots about the fulcrum 41 (see Figures 13 , 14 ), which in turn is fixed to the protective half-shell 16, described more fully in what follows.
  • lever 39 slides in the eyelet 40 (see Figure 13 ), which is made in the shell 16 and through which the lever can come out of the shell 16 itself.
  • the stretch of tube 43 having the shape of a bellows, or in any case flexible (see Figure 13 ), enables connection of the delivery of the hollow piston 33 of the pump 21 within the roller 5 and supply of the latter with the paint delivered by the pump 21 irrespective of the inclination of the pump itself with respect to the shell 16, 16C.
  • the desmodromic-cam actuation 36, 37 just described does not require return springs for guiding both the delivery stroke and return stroke of the piston 33, it enables actuation of the pump 21 with a smaller effort on the part of the roller 5, and hence with greater convenience for the user. Furthermore, the system of levers and cams enables prevention of any risk of blocking of rotation of the roller 5.
  • the two half-shells 16, 16C (see Figures 1 , 7 ) have the function of protecting the pump 21 and the corresponding actuation mechanism from possible drops of paint.
  • the present example is moreover provided with means of regulation of the capacity of the pump 21, thus exemplified (see Figures 6 , 13 , 14 , 17 , 18 , 21, 22 ):
  • the capacity of the pump is regulated, that is, by varying the position of the pin 47 (see Figures 6 , 17, 18 ).
  • the above system for regulation of the capacity enables an adjustable flow to be obtained as desired, with considerable precision and according to the requirements of the moment. Thanks to the uniform and constant distribution, it is possible to save up to 30% on the amount of paint with respect to traditional systems.
  • Figures 8-12 refer to a second example of a painting roller.
  • the supply means of the roller 5 comprise a peristaltic pump, designated, as a whole, by the reference number 48 (see Figure 8 ).
  • the peristaltic pump 48 can have two or more rollers 49 (see Figure 8 ) and is actuated by a series of gear wheels 50-58 (see Figures 9-12 ):
  • Figures 11, 12 show the speed-reduction system (gear wheels 50-52), which, in the present example, connects the system of wheels and ratchet mechanisms 50-58, 61-64 to the roller 5, 19, to the threaded bushing 7, and to the rotating support 6.
  • the one-directional ratchet-gear couplings 61, 62 can be replaced with other types of one-directional coupling; the coupling between the gear wheels 54, 56 and 55 can be replaced by other transmission means designed to turn the second driver coupling element 55 in the same direction of rotation as the first driver coupling element 54.
  • the coupling between the gear wheels 57, 58 can be replaced by other reversal means suitable for rotating the first driven coupling element 62 in a direction of rotation opposite to that of the second driven coupling element 61.
  • the position of the gear train for transmission 54, 55, 56 and of the gear train for reversal 57, 58 can be reversed with respect to Figures 9, 10 by setting the gear train for reversal further upstream, i.e., closer to the desmodromic cam actuation, and the gear train for transmission further downstream, i.e., closer to the rotor 60 (said variant requires the two one-directional couplings 61, 62 to have concordant directions of rotation of uncoupling, unlike the example of Figures 9, 10 , in which the two one-directional couplings 61, 62 must have discordant directions of rotation of uncoupling).
  • Figure 20 regards a fourth embodiment of a self-supplied painting roller.
  • the roller 5 has a thinner frustoconical shape and is provided with an end washer 65 made of non-absorbent and non-transpirant material 65, which enables painting without dirtying doorposts, frames, etc.
  • the roller is easy to use for anybody, even for the least expert and for those persons who, for reasons of habit or practicality, do not like to use traditional rollers.
  • the spring knob 47G which may be gripped by the user, blocks inclination of the pump 21 with respect to the shell 16, pinching the edges of an appropriate eyelet (not shown and made in the shell 16 itself) against a contrast made in the pin 47.
  • variable-volume chamber is defined also by a cylindrical cavity 214', made within an outer body 213 obtained, for example by injection moulding, in a single piece, instead of assembling a number of pieces moulded separately.
  • the piston 33 slides within a cylindrical cavity 214 defined by the two elements 211, 212, which have been moulded separately and subsequently ultrasound welded along the joining surface 210.
  • the coating made of absorbent material 19 is fixed on the roller 5 not via bonding, as in the example of embodiment of Figure 3 , but by being pinched at the end between the roller 5 and the rotating tubular support 6. This enables removal or replacement of the absorbent coating 19, without having to dismantle or replace also the roller 5 and other pieces connected thereto.
  • the rotating tubular support 6 is blocked axially on the fixed tubular support 6A, not via the system of clinching with the radial projections 10 and the notches 12 of Figure 4 , but rather by means of the sliding tab 10B, which, in the inserted position can be engaged, for example, in the annular groove 11 of Figure 5 , whilst, in the extracted position, it enables the roller 5 and the rotating tubular support 6 to be slid out of the fixed tubular support 6A, with a faster mode of operation as compared to the clinching system of Figure 4 .
