Definitions

  • the invention relates to a carpet care device according to the preamble of claim 1.
  • the object of the invention is to design and develop the known maintenance device in such a way that torque transmission is as favorable as possible and manufacture is as inexpensive as possible.
  • a generic carpet care device which is characterized on the one hand by favorable torque transmission due to lower forces and on the other hand has the advantage of lower production costs.
  • the torque transfer of the brush rollers now takes place via the hollow shaft, while the support is carried out via the support mandrel.
  • the mandrel has only the function of a support function. It can be smooth throughout and thus represents a very simple, inexpensive to manufacture automatic part.
  • the torque transmission to the brush rollers takes place via the counterclaws of the hub of the drive gear, which counterclaws engage positively in the clutch claws of the clutch bushings, which carry end pieces at the end. These are in turn plug-in with the brush rollers.
  • the shaft receives a bridge-like support on both sides of the drive system through the ball bearings on the housing side, which are penetrated by the coupling sleeves of the head pieces.
  • the brush rollers and the components interacting with them can be assembled by means of plug-in assembly.
  • the drive wheel and the ball bearings on both sides of it are to be positioned.
  • the coupling sleeves are then to be inserted through the ball bearings, the coupling claws of which engage in the counterclaws of the hub of the drive gear.
  • the next step is to push the brush rollers onto the shaft ends, making the push-fit with the head pieces. Replacing the brush rollers after any wear is therefore also very simplified.
  • the coupling sleeves have resilient fingers with bevels that snap in front of the inner ring of the ball bearing. This means that after the coupling bushes have been pushed through the ball bearings, the coupling bushes are fixed in the axial direction. If the shaft is then inserted, the resilient fingers cannot come out of their locked position.
  • the ball bearings are surrounded by cup-shaped sleeves of the housing and the shaft extends beyond the sleeves into the hubs of the brush rollers, the end openings of which are closed by clipped-on covers which have a cup-shaped entry bore for the end of the shaft .
  • the housing sections accommodating the ball bearings can accordingly be of shell-like design. The insertion of the ball bearings is simplified.
  • the cup-shaped sleeves placed on the housing sections secure the position of the ball bearings, which also support the shaft. The ends of these engage in the hubs of the brush rollers and in the cup-shaped entry bores of the covers clipped into the front end openings.
  • the two covers are used to axially secure the shaft. After removing a cover, it is possible to pull out the shaft.
  • ejector springs for the brush rollers can be assigned to the head pieces.
  • the carpet care device shown has a dash-dotted housing 1. This is approximately T-shaped. In the T-bar 2 there is a gear motor, not shown, while the T-bar 3 receives brush rollers 4, 5.
  • a gear bridge 6 is fastened in the T-web 2 of the housing 1. This sits on both sides of a middle drive point in two Half shells 7, 8 on.
  • a drive gear 9 extends between the two half-shells 7, 8 and sits non-rotatably and immovably on a hub 10. The latter protrudes on both sides of the drive gear 9 forming the drive point and forms counter-claws 11 at the end.
  • clutch claws 12 which are arranged coaxially to the hub 10 and have clutch bushings 13 which pass through the inner rings 14 of ball bearings 15.
  • the ball bearings 15 are embedded in the half-shells 7, 8 of the gear bridge and secured there by shoulders 16, 17.
  • a cup-shaped sleeve 18 is pushed over each half-shell 7, 8, the cup edge 18 'of which is supported on a step 19' of the gear bridge 6.
  • Each coupling sleeve 13 is provided with resilient fingers 20 which extend in the axial direction and which form bevels 21 at their ends facing away from the drive point.
  • the finger ends 22 extend in front of the inner rings 14 of the ball bearings 15.
  • the coupling bushes 13 are axially immovable by a support shoulder 23 opposite the finger ends 22.
  • each coupling sleeve 13 continues into a head piece 24.
  • four bayonet slots 25 are worked in from the front side of the head piece 24 in such a way that the insertion ends 25 'are widened in a funnel shape.
  • the head piece contains a central bore 26 for receiving a compression spring 27.
  • the bayonet slots 25 crosswise arranged webs 28 engage, which connect the brush roller casing 29 to the hub 30 of the brush roller.
  • the webs 28 extend in the sections 25 "of the bayonet slots 25.
  • the brush rollers 4, 5 are equipped with spoke walls 31 which connect the hub 30 to the casing 29.
  • each lid 32 has a pot shape.
  • the outwardly directed pot edge 33 is supported on the front end of the brush roller 4 or 5. From the bottom of the pot, there are webs 34 directed inward of the brush rollers, the outward-facing latching lugs 35 of which engage with clips in the shape-matched openings 36 of the brush roller 4 and 5, respectively.
  • Each pot bottom of the cover 32 forms brush-oriented bushes 37.
  • the free ends 39 of a support mandrel 40 which supports the hub 10 of the drive gear 9, the coupling bushes 13, the head pieces 24 and the hubs 30 of the brush rollers 4, protrude into the inlet bores 38 of the bushes 37 of the cover , 5 interspersed. All of the above-mentioned components are rotatably seated on the mandrel 40, so that the drive gear 9, which is rotated by a worm (not shown), drives the coupling sleeves 13 with the head pieces 24 attached to them via the claw coupling connections 11, 12, which in turn, according to the bayonet slots 25, the Take brush rollers 4, 5 with you.
  • the last assembly step is to bring the brush rollers 4, 5 into a snap-in connection with the head pieces 24.
  • the webs 28 are inserted into the bayonet slots 25, the compression spring 27 serving as an ejector spring being charged. After the brush roller has been rotated, the webs 28 reach the internally assigned sections 25 ′′ of the bayonet slots 25.
  • covers 32 are not yet assigned to the brush rollers 4, 5, this can then be done by clipping them on, so that the ends of the support mandrel 40 lie in the inlet bores 38 of the covers 32, thereby achieving an axial securing of the position.
  • the brush rollers 4, 5 are replaced by pressure on them in the direction of the drive position and subsequent rotation, the webs 28 of the brush rollers 4 being able to leave the bayonet slots 25.
  • the removal of the brush rollers from the support mandrel is supported by the ejector springs 27.
