Definitions

  • the invention relates to a vacuum cleaner equipped with castors.
  • a vacuum cleaner which has rollers.
  • the rollers have ribs, which start from a hub of the impeller and are connected to an outer tread, and give the roller the required stability.
  • rollers have a wall with a curved cross section between a race and a hub.
  • the rollers Due to the curved wall between the hub and the race, the rollers are given a high degree of elasticity. Even if the casters are made of a hard material, the curved shape of the wall is able to absorb shocks.
  • the rollers have a simple structure and can therefore be manufactured inexpensively.
  • An embodiment of the vacuum cleaner is particularly advantageous in which the wall has an S or a Z-shaped structure in cross section. This shape achieves a high degree of elasticity with low material consumption.
  • reinforcing ribs are additionally provided, which are arranged on at least one of the two end faces.
  • the reinforcing ribs each extend from the wall in their curved area.
  • the reinforcement ribs give the wall greater stability. In order not to reduce the elasticity, the ribs are not connected to the hub or to the race.
  • these ribs extend from the hub and are directed against the curved area of the wall. In this case, too, the ribs are not connected to the curved wall in order not to reduce the elasticity.
  • the race has a spherical contour on its tread. This measure also supports the elasticity of the rollers.
  • the roller can be made inexpensively from polypropylene (PP) or one of its copolymers.
  • the running ring of the roller has a surface made of flexible material. This results in additional damping and an improved slip resistance of the roller on smooth floors.
  • a running surface made of flexible plastic material is preferably injection molded onto the running ring. This tread can be inexpensively molded onto the race in a two-component injection molding process.
  • thermoplastic elastomers (TPE) and rubber-based materials can be used as suitable plastic materials.
  • FIG. 3 shows the roller in a sectional view A-A according to FIGS. 4 and
  • Fig. 5 is a roller with a tread made of soft elastic material.
  • a vacuum cleaner has castors.
  • the rollers are constructed like a roller 1 (Fig. 1).
  • the roller 1 has a hub 2, via which it is slidably connected on an axle connected to the housing of the vacuum cleaner or supported by ball or roller bearings.
  • the roller is made of a plastic, in particular a hard plastic such as polypropylene, but it can also consist of a more elastic plastic.
  • the hub 2 has a circular projection 21 toward the axis on its front side and a likewise circular projection 22 on its rear side.
  • a wall 3 connects to the hub 2 and connects the hub 2 to a race 4.
  • the wall 3 has a first region 30 which extends in the radial direction from the hub 2 on the front side to close to the center of the radius of the roller 1. This is followed by a second region 31, which extends obliquely from the front to the rear of the roller 1.
  • the slope of the area 31 can be selected differently.
  • the region 31 can also run coplanar to one of the two lateral surfaces of the hub 2 or coplanar to one of the two lateral surfaces of the race 4.
  • a region 32 (FIG. 2) adjoins the region 31, which extends in the radial direction from the region 31 on the rear side of the roller 1 to the race ring 4.
  • the wall 3 thus connects the hub to the race 4 through its three regions 30, 31 and 32.
  • Ribs 5, 6 are provided to support the stability of the roller 1.
  • the ribs 5 extend from the region 31 of the wall 3 in the direction of the inner lateral surface of the race 4, but do not touch it. Only in the case of heavy weight loads can the ribs 5 touch the outer surface.
  • the ribs 6 extend from the area 32 of the wall 3 in the direction of the outer circumferential surface of the hub 2.
  • the ribs 6 also do not touch the circumferential surface of the hub 2, but can hit them in the event of heavy weight.
  • ribs can also be arranged on the outer circumferential surface of the hub 2 and protrude in the direction of the region 31 of the wall 3 without touching it, except in the case of heavy weight.
  • the roller preferably has a spherical tread 41.
  • the curved shape of the wall 3 is either Z-shaped (see. Fig. 3, 4) or S-shaped. Other curved shapes are also conceivable. In particular, a double S shape or a double Z shape is also possible.
  • the invention provides an elastic roller 1 with a hub 2 and a roller 4.
  • the hub 2 and the race 4 are connected to each other by an S or Z-shaped curved wall 3.
  • Ribs 5, 6 are provided to reinforce the wall 3 or the hub 2.
  • the race 4 has a surface made of flexible material (FIG. 5).
  • a soft elastic tread 41 made of a suitable plastic material is molded directly onto the race 4. In a simple manner, the soft elastic tread 41 can be produced together with the roller 1 in a two-component injection molding process.
  • the race 4 is provided on its surface with a circumferential recess 51, into which the flexible material is molded.
