Definitions

  • the invention relates to a belt-suspendible holder for an electric motor for driving a hand tool.
  • rotary hand tools such as cutters and the like.
  • the tool is driven via a flexible shaft by a high-speed motor (24,000 rpm).
  • the present invention concerns a belt-suspendible holder of the type disclosed in the preamble of claim 1 (US-A-3 219 129).
  • the holder particularly one for a high-speed motor, has the features disclosed in the characterizig part of claim 1.
  • the fixed carrier member may be fitted with two end stops between which the pivoting holder member is movable.
  • the two members may be interconnected by a pivot and an intermediate ring of appropriate material, so that upon bending of the flexible drive shaft, the pivoting member pivots relative to the fixed member before the bend in the shaft becomes unacceptably sharp.
  • an insertion tube may be mounted on the fixed member of the holder above the pivoting member.
  • the tool motor holder comprises a fixed carrier 1 and a motor holder 2 which can be pivoted relative thereto, both made of plate material.
  • a fixed carrier 1 Formed in the fixed carrier 1 are lateral apertures 3 for receiving a belt (not shown). Further, a tube 4 is mounted on the carrier 1.
  • the shape of the pivoting motor holder 2 depends on the configuration of the motor to be mounted therein and, in the embodiment shown, has an end 5 bent over at right angles, having a passage 6 for the front end 7 of an electric motor 8, which, in the case of a cutter for mending woodwork, is typically a high-speed motor.
  • the motor holder 2 comprises an axial clamping screw 9 which can engage with the rear end of the motor housing, thereby retaining it against the bent end 5.
  • the members 1 and 2 of the tool motor holder are interconnected by a pivot 10 with interposition of a sliding disc or washer 11 generating a certain braking friction during pivotal motion of the motor holder 2, in such a manner that when unloaded, the motor holder 2 retains any pivotal position relative to the carrier 1 and does not change its pivotal position until a pivotal force is exerted, generated by a flexible shaft on the motor 8 being pulled into a sharp bend.

Claims (4)

  1. Support suspendu par courroie, pour un moteur électrique servant à entraîner un outil manuel par l'intermédiaire d'un arbre flexible, comportant un organe de support en forme de plaque, destiné à être suspendu à une courroie, et un organe portant le moteur relié à pivotement à l'organe de support, caractérisé en ce que ledit organe de support (1) est monté en position fixe sur une courroie, et ledit organe (2) portant le moteur présente une partie en forme de plaque, essentiellement parallèle à l'organe de support (1) et reliée à pivotement (10) à celui-ci par contact à friction, ledit organe porteur (2) présentant des moyens (5, 9) en saillie par rapport à la partie en forme de plaque, dans lesquels le moteur (8) peut être fixé avec l'arbre du moteur en position essentiellement horizontale et parallèle à sa partie en forme de plaque, le contact à friction entre l'organe de support (1) et l'organe porteur (2) étant tel que lorsqu'il n'est pas en charge, l'organe porteur (2) conserve toute position de pivotement par rapport à l'organe de support (1) jusqu'à ce qu'une force de pivotement soit exercée sur lui par l'arbre flexible du moteur (8).
  2. Support selon la revendication 1, caractérisé en ce que l'organe fixe de support (1) est équipé de deux arrêts d'extrémité (12) entre lesquels l'organe porteur pivotant (2) peut se déplacer.
  3. Support selon la revendication 1 ou 2, caractérisé en ce que les deux organes (1, 2) sont reliés par un pivot (10) et une rondelle (11) en matériau approprié, de telle sorte que lorsque l'arbre flexible d'entraînement (13) est courbé, l'organe porteur (2) pivote par rapport à l'organe de support (1) avant que la flexion de l'arbre devienne inacceptablement accusée.
  4. Support selon l'une quelconque des revendications précédentes, caractérisé en ce qu'un tube d'insertion (4) pour outils est monté sur l'organe fixe de support (1), au-dessus de l'organe porteur (2).
