Definitions

  • Control pedals are known for an electrical machine, in particular for a sewing machine, comprising a housing and a movable member shaped to be actuated by the foot of the user, this member acting on a variable electrical element allowing the activation and adjustment of the machine speed, an electric cord being provided to connect the pedal to the machine.
  • the present invention aims to make pedals of this kind more practical to use.
  • the pedal which is the subject of the invention is characterized in that said member is in the form of a handle capable of occupying two positions, one of which is used for transporting the pedal and the other for controlling the speed of the machine.
  • the sewing machine shown in FIG. 1 usually comprises a base 1, a lower arm 2, an upright 3 and an upper arm 4 carrying a fabric press 5.
  • the supply of this electric machine is done by means of a plug 6 intended to be engaged in an outlet of the distribution network, the current being brought to a control pedal 7, which is connected by an electric cord 8 to the electric motor. that the sewing machine contains.
  • the pedal 7 has a movable member 9 intended to be actuated by the foot of the user, the heel of which normally rests on a support plate 10. This member 9 allows the machine to start up and its speed to be adjusted. sewing.
  • the pedal 7 comprises a housing 11 and, on two lateral faces of this housing, a portion 12 forming a coil to allow the cord carrying the plug 6 to be wound therein, the cord 8 respectively.
  • FIG. 2 shows the pedal 7 in the non-use position, in which the member 9, which is in the form of a handle, is folded over the plate 10. It can also be seen that the electrical cord 8 has been wound around its portion forming a coil. Finally, FIG. 2 also shows in phantom, the two extreme positions of the member 9 for the position of use, namely the position 9a corresponding to the stopping of the machine and the position 9b corresponding to its maximum speed. .
  • the movable member 9 is U-shaped comprising a central branch 13 and two lateral branches 14, the free ends of the latter being connected together by a rod 15.
  • This rod pivots in support bearings 16 and 17 integral with the side walls of the housing 11.
  • the rod 15 carries two cams 18 and 19.
  • the cam 18 acts on a switch 20 and is shaped to act on the switch in order to interrupt the supply of the machine, as soon as the member 9 is moved from its position 9a to be brought into its position allowing transport and storing the pedal when not in use. This provides a higher level of safety, making it possible to avoid any untimely start-up of the machine, for example, in the event of a fault in an electrical element supplying the motor.
  • the other cam 19 has the shape of a finger acting on the rod 21, such as a potentiometer, this rod being returned upwards by a spring 22 housed in a housing 23.
  • the rod 15 still carries a disc 24 having a blind bore 25, in which is housed a ball 26 subjected to the action of a spring 27, this ball is engaged with a recess 28 of the bearing 16.
  • This arrangement forms an elastic notch to maintain the member 9 in its transport position.
  • control pedal has been described with reference to use for a sewing machine, but it goes without saying that it can be used for any device or machine whose operation is to be controlled using a foot pedal. ordered.
