Definitions

  • the invention relates to a carpet care device according to the preamble of claim 1.
  • a support shaft is arranged in a hollow shaft formed from a plurality of parts which can be plugged together, the torque being transmitted to the brushes provided on both sides of the drive point via the hollow shaft.
  • the high manufacturing costs of the hollow shaft and the complex assembly prove to be disadvantageous in this configuration.
  • the object of the invention is based on the object of designing a carpet care device of the type required in such a way that, in addition to favorable torque transmission to the brush rollers, the production costs can be reduced and the assembly simplified.
  • a generic carpet care device which is characterized on the one hand by simple assembly and on the other hand has the advantage of lower production costs.
  • the torque transfer of the brush rollers is no longer carried out via the shaft itself. This only has the function of a support function.
  • the shaft can be smooth throughout and thus represents a very simple, inexpensive machine part to be produced.
  • the torque is transferred to the brush rollers via the counterclaws of the hub of the drive gear, which counterclaws form-fit into the clutch claws of the coupling sleeves, which have end pieces at the ends. These are in turn plug-in with the brush rollers.
  • the shaft receives a bridge-like support on both sides of the drive point 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 bushes are 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 move out of their secured 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 simultaneously support the shaft. The ends of these engage in the hubs of the brush rollers and in the cup-shaped inlet bores in the End openings clipped in lid.
  • 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 are assigned to the head pieces so that the brush rollers do not accidentally come out of their plug-in snap-in connection.
  • the carpet care device shown has a dash-dot 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 continues on both sides of a middle drive point in two half-shells 7, 8.
  • 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. These are in positive engagement with clutch claws 12, which are arranged coaxially to the hub 10, 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 incorporated from the end face 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 in clips 36 of the brush roller 4 and 5 that conform to the shape.
  • Each pot bottom of the cover 32 forms brush-oriented bushes 37.
  • the last assembly step consists in bringing the brush rollers 4, 5 into plug-in locking 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 enter the sections 25 ′′ of the bayonet slots 25 assigned to them.
  • the brush rollers 4, 5 are replaced by pressure on them in the direction of the drive point and subsequent rotation, the webs 28 of the brush rollers 4, 5 being able to leave the bayonet slots 25.
  • the removal of the brush rollers from the shaft is supported by the ejector springs 27.
