Definitions

  • the invention relates to a mouthpiece for a vacuum cleaner on which the suction unit is articulated decentrally on a tilting joint, the weight of the suction unit acting outside of the center of gravity of the device and in particular electrically operated brushing and polishing machines for floor treatment with several brushing or polishing disks.
  • the object of the invention is therefore to ensure that the weight of the machine is distributed so evenly that the above-mentioned disadvantages no longer occur. This object is achieved by the invention set out in claim 1.
  • the sub-claims 2 to 5 are advantageous embodiments of the invention.
  • the advantages of the inventive solution are, in particular, that none due to the uniform weight distribution of the machine over all disks one-sided wear of some discs occurs more.
  • the disks have to be replaced less frequently and the spare parts costs are saved.
  • the device also no longer swings out to the side, which means that working is much easier and more practical for the user.
  • a switch that automatically switches the device off when it is switched off ensures that it does not move automatically from its own place to a point on the front attachment even when the attachment is fully weight-bearing.
  • Figure 1 shows the distribution of forces in the brushing and polishing machine, F2 (4) being the center of gravity of the vacuum cleaner (2) outside the polisher (1) and F1 (3) being the center of gravity of the polisher (1). Because of these forces (3 and 4), the contact force of the working discs (6) on the ground is different. In order to compensate for this, compensating springs (11) are arranged on the tilt joint (8). You shift the weight force F2 (4) lying outside the front attachment (1) to the hand load F3 (5) and the center of gravity of the front attachment (1) F1 (3).
  • two pivot arms (9) are arranged at the pivot point (7) of the tilting joint (8).
  • the compression springs (11) act on these via guide parts (10).
  • the dashed lines (13) with the degrees of the working position of the tilt joint (8) show in their extensions (14) the associated position of the swivel arms (9).
  • the design of the swivel arms (9), compression springs (11) and guide parts (10) must be chosen according to the type of other components and the problem.
  • the compression springs (11) are relaxed when the tilt joint (8) is in a horizontal position, and when it is in a vertical position they support stability with little force distribution. If the device is switched off or the tilt joint (8) is moved to a position of approx. 90 ° with the jam eye (2), a switch (12) is actuated by a swivel arm (10) from approx. 60 - 80 ° working position and thereby the device is switched off.
