Definitions

  • the present invention relates to a control pedal for an electric 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 at least one electrical control device allowing the starting and adjusting the speed of the machine, an electric cord being provided to connect the pedal to the machine.
  • US Patent 4,751,354 refers to a control member for electric motors.
  • a U-shaped bracket allows you to lock a control button in the operating position.
  • application FR 2,456,378 relates to a safety device intended for power tools and comprises a movable wall of a housing controlling the running of the engine. This movable wall can be blocked by a hook in the stopped position of the motor and unlocked by means of a U-shaped stirrup acting on the hook.
  • the object of the present invention is to make the control pedals more practical to use, in particular to make them handy and suitable for transport, while increasing their operational safety.
  • control pedal forming the subject of the invention is characterized in that said movable member is provided with a first piece shaped to serve as a handle for transporting the control pedal, this movable member being mounted pivotally to the housing so as to occupy at least one operating position in which said first part is raised so that it can be actuated by the foot of the user and at least one second transport position in which the first part is lowered to serve transport handle, the movable member comprising at least a second part arranged so as to act on said electrical control device so as to control the start-up and the adjustment of the speed of the machine in said first position of the movable member and to interrupt the electrical supply to the machine in said second position of the movable member.
  • Figure 1 shows a sewing machine fitted with this pedal.
  • Figure 2 is a side view of this pedal.
  • Figure 3 shows in detail part of the interior mechanism of the pedal.
  • Figure 4 is a plan view of this pedal with a partial cutaway.
  • the sewing machine shown in FIG. 1 usually comprises a base 1, a lower arm 2, an upright 3 is 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. Superior security is thus obtained, making it possible to avoid any untimely starting of the machine, for example, in the case of a fault in an electrical element ensuring the supply of 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.
