  • the invention relates to a brush having a brush plate rotatably arranged on a brush back and in which the two brush parts are connected with each other by means which are rotatable relative to each other.
  • Brushes with rotatable brush plates are known in various embodiments. They have been found to be particularly suitable for brushes with handles, in which the bristles provided for the brushing procedure are embedded in a flexible carrier such as a woven fabric, closely alongside each other and with their points all obliquely inclined in the same direction. Such brushes fitted with inclined bristle material always have to be moved in the same direction over the surface to be cleaned, that is to say in the direction of inclination of the bristles. If brushing is in a direction opposite to the direction of inclination, the particles picked up by the brush and held in the spaces between the inclined bristles, are released and are again deposited on the brushed surface.
  • a flexible carrier such as a woven fabric
  • a known brush of this kind comprises a brush plate one side of which has the brush material fixed thereto so that the brush plate and brush material form a unit.
  • This brush plate is inserted in a brush back which is provided with a handle and it is held fixed in the brush back by means of a helical spring the upper end of which bears against an abutment connected with the brush plate and the lower end of which is seated in a recess which is formed in a part screwed on to an inwardly extending projection of the upper part of the brush plate.
  • a helical spring In order to rotate the brush plate, this is gripped at its somewhat protruding margin, pulled out of its seat against the action of the spring and rotated. After releasing the base, the spring draws this again against the upper part of the brush and holds the parts together.
  • a helical spring it has also been proposed to use a flat spring or a spring plate which is screwed tight on to the brush back and the brush plate at suitable regions.
  • a further embodiment has partly overcome this known disadvantage, by avoiding screw connections when fixing the brush plate to the brush back.
  • the brush plate has a centrally arranged sleeve which extends upwardly from the side of the brush plate remote from the brush surface.
  • the lower section of this sleeve has a larger diameter than the upper section, so that a step is formedon the outer periphery of the sleeve, on which the lower end of a sleeve projecting from the inner side of the brush back rests.
  • This lower end of the sleeve forms the seat for one end of the helical spring which surrounds the upper narrower section of the sleeve of the base plate, that is to say, is inserted in the intermediate space between the sleeves, one of which surrounds the other.
  • a bolt having a head is provided in the upper narrow section of the sleeve, the bolt being slotted from below, and having hooks at its lower end which latch on to the lower side of the upper limit of the wider section of the sleeve projecting from the brush plate.
  • the brush plate is fixed on to the brush back without screwing or pin connections.
  • the head of the bolt which extends through an opening in the brush back, is pressed downwardly. Thereby, the helical spring is compressed and the base plate is pressed out of its seat so that it can then be rotated.
  • This brush embodiment contrary to the firstmentioned brush, has the advantage that automatic assembly by way of a tool can be performed.
  • the individual parts only have to be appropriately inserted and the tool closed.
  • a number of individual parts are required, as well as a helical spring.
  • the invention consists in a brush comprising a brush plate rotatably arranged on a brush back and in which these two brush parts are connected with each other by members which project from the brush plate and the brush back and intcrengage in the interior of the brush so as to allow relative rotation of the said members.
  • the said members having cooperating detent formations which maintain the said members in their interengaged relation while allowing the relative rotation, a ring surrounding one of the said members at a spacing being provided on the side of the brush plate remote from its brushing surface, diametrically oppositely disposed axial ribs being arranged on the outer wall of the ring, which engage in axial grooves, which are formed in a sleeve which extends from the inner side of the brush back and which surrounds the ring.
  • the said interengaging members are sleeves, one of them being slotted so as to form a plurality of segment shaped fingers which can resiliently yield to allow engagement of the detent formations when the said two brush parts are being assembled together.
  • the said member projecting from the brush plate extends centrally therefrom and is formed with a continuous wall, and the said member projecting from the brush back is the slotted one.
  • the said member projecting from the brush plate is provided at its outer periphery with a continuous groove in which projections latchingly engage, which extend inwardly from the free lower ends of the segment shaped fingers.
  • the brush plate may comprise a base plate and a shallow frame applied at the side of this base plate remote from the brushing surface, the said member which projects from the brush plate being arranged on the base plate and the ring being arranged on the frame.
  • the ring may be disposed on the upper side of the frame and is fixed to the frame only at two oppositely lying arcuate sections, the arcuate sections which lie between these being disposed over the opening defined by the frame.
  • the sleeve which surrounds the ring may have an elliptical cross section, the minor axis of which passes through the groove regions of said sleeve.
  • the axial ribs on the ring may be of triangular or semicircular shape in cross section.
  • the axial grooves may have outwardly tapering sidewalls.
  • the brush plate and brush back may be made of plasties.
  • FIG. 1 is a side view of a brush with a handle
  • FIG. 2 is a vertical longitudinal section through the brush of FIG. 1;
  • FIG. 3 is a section along the line A A in FIG. 2;
  • FIG. 4 is a partial view of the rotary parts of the brush.
  • the brush B consists essentially of two parts, namely the brush back 1 with the handle 18 and the brush plate 2 provided with the brush surface 3, which in the illustrated embodiment consists of a base plate 2a and a shallow frame 2b applied thereon.
  • the brush back and brush handle are advantageously of unitary construction.
  • the brush surface consists of inclined bristle material for example, which is firmly connected with the brush plate 2 in any known manner. In the illustrated embodiment, the brush material is clamped fast by the frame 2b.
  • a sleeve 4 is centrally provided, which preferably takes up the entire height of the cavity in the brush.
  • a recess is provided in the brush back 1, in which the sleeve 4 terminates.
  • the opening of the sleeve is closed by a plate 6.
  • a groove 5 is provided whichv extends around the outer periphery of the sleeve 4, approximately at its middle.
  • a sleeve 7 projects, which engages around the sleeve 4, of the base plate 20.
  • the sleeve 7 has axial slits which divide it into segment shaped fingers 7a, 7b, 7c, and 7d (FIG. 3) in order to give the sleeve suitable resilience.
  • the free lower ends of the segment shaped fingers are provided with inwardly directed projections 8 which engage in the groove 5 which extends around the outer periphery of the sleeve 4, after the two brush parts, that is to say the brush plate 2 and the brush back 1, are assembled together.
  • Each projection 8 preferably extends over the entire breadth of the respective finger of the sleeve 7, and is shaped in the form of a hook in order to hold the brush plate 2 firmly but rotatably on the brush back 1.
  • the sleeve 7 engages around the sleeve 4 of the brush plate resiliently in such a manner that the two sleeves are rotatable relative to each other.
  • a ring 9 is furthermore provided on the side of the brush plate 2 remote from the brushing surface 3, and surrounds the two sleeves 4 and'7 at a distance.
  • This ring is fixed on the upper side of the frame 2b, oppositely lying arcuate sections of the ring 9 lying free over the recess A in the frame (FIG. 4).
  • the ring 9 has two diametrically oppositely disposed axial ribs 10 at its outer wall, which engage in axial grooves 12 (FIG. 3)
  • the axial grooves 12 are provided with outwardly tapering side walls, whereas the axial ribs 10 on the ring 9 which fit into the longitudinal grooves, are preferably constructed with semi-circular or possibly triangular cross section. These tapering or rounded-off surfaces allow the ribs to move out of the grooves by a rotary movement.
  • the ring 9 is cylindrical, whereas the second sleeve 11 of the brush back 1 has an elliptical cross section.
  • the minor axis of the ellipse extends through the grooves 12 so that necessarily the major axis lies at an angle of to the grooves 12.
  • the intermediate space 13 formed thereby between the ring 9 and the sleeve 11, facilitates the rotation of the brush plate 2 after the ribs 10 have been released from the grooves 12.
  • the brush plate 2 If the brush plate 2 is to be rotated, it is simply gripped laterally and turned with slight pressure. Thereby the axial ribs 10 of the ring 9 move laterally out of the axial grooves 12 of the sleeve 11 and without great force can be moved through the intermediate space 13. After a rotation of the brush plate 2 through the ribs 10 again latch into the grooves 12.
  • an arrow can be provided on this cover plate, which indicates the direction of bristle tips and thus the brushing direction necessary.
  • the upper side of the brush back can alternatively be of continuous construction and thearrow for the brushing direction can be provided at any other suitable place.
  • the ring 9 is fixed only at two oppositely disposed arcuate sections of its lower peripheral edge, and the arcuate sections lying therebetween are disposed freely above the recess A in the frame 2b, a sufficient resilience is ensured which gives a low friction release, rotation and latching of the brush plate.
  • the sleeves and the ring may be constructed integrally with the brush back and the parts of the brush plate, respectively.
  • a brush with a rotatable brush plate is thus provided, with a minimum of individual parts, without the requirement of any kind of spring, and which can be assembled in a single working operation with the minimum number of actions, with the aid of a tool, an opti mum manufacturing simplification thereby being achieved.
  • a brush comprising a brush plate rotatably arranged on a brush back and in which these two brush parts are connected with each other by members which project from the brush plate and the brush back and interengage in the interior of the brush so as to allow relative rotation of the said members through 360, the said members having co-operating detent formations which maintain the said members in their interengaged relation while allowing the relative rotation, a ring surrounding one of the said members at a spacing being provided on the side of the brush plate remote from its brushing surface, diametrically oppositely disposed axial ribs being arranged on the outer wall of the ring, which engage in axial grooves which are formed in a sleeve which extends from the inner side of the brush back and which surrounds the ring, said ribs and grooves acting as detent means.
  • a brush as claimed in claim 1 wherein the brush plate comprises a base plate and a shallow frame applied at the side of this base plate remote from the brushing surface, the said member which projects from the brush plate being arranged on the base plate, and the ring being arranged on the frame.
