Definitions

  • the present invention relates to a safety lock for electrical devices, particularly for electrical switches.
  • the aim of the present invention is to provide a safety lock for electrical devices, particularly for the handle of electrical switches, which has improved performance and is less awkward to use.
  • An object of the invention is to provide a safety lock which is cheap and simple from the point of view of production.
  • a safety lock for electrical devices particularly for electrical switches, characterized in that it comprises a base body, a sliding body which can move along the longitudinal axis of the base body, and a hook member which is fixed with respect to the base body and is adapted to determine at least two positions: a closed position, in which the hook member engages a control member of an electrical device, so as to prevent its functional movement, and an open position, in which the hook member can be disengaged from the control member in order to allow actuation of said control member.
  • the safety lock for electrical devices according to the invention is particularly suitable for locking the handle 3 of an electric switch 5, as shown in the present example.
  • the handle 3 of the switch 5 has two recesses 7 which are respectively arranged above and below the grip portion 9, so that one recess 7 is always located at lateral holes 11 formed in the body of the switch both when the handle is in the closed-switch position and when it is in the open-switch position.
  • FIGS. 1 and 8 illustrate the open-switch position.
  • the lock 1 includes a base body 13, a sliding body 15 which can move along the longitudinal axis of the base body 13, and a hook member 17 which is stationary with respect to the base body 13.
  • the hook member 17 is constituted by a wire-like body which has two flexible arms 19, each of which has a hook-shaped end 21; the flexible arms are joined by a transverse arm 23 which is rigidly coupled to the base body 13.
  • the transverse arm 23 is arranged in a slot which is formed in a block 25 which is rigidly coupled to the base body 13.
  • the sliding body 15 includes two shaped walls 27 and a central member 29 which are adapted to guide the movement of the flexible arms 19 of the hook member 17.
  • the flexible arms 19 are in fact set at an appropriate angle with respect to the longitudinal axis of the lock, so that a movement of the sliding body 15 with respect to the base body 13 is matched by a movement of the flexible arms 19.
  • the flexible arms 19 determine two positions: a closed position (FIGS. 3, 5, 6 and 7), in which the arms are spaced apart and the hook-shaped ends 21 are located outside the tip 31 formed by the front ends of the sliding body 15 and of the base body 13, and an open position (FIGS. 2 and 4), in which the arms are joined and the hook-shaped ends 21 lie inside the tip 31.
  • the sliding body 15 In the closed position (FIGS. 3, 5, 6 and 7), the sliding body 15 remains substantially inside the base body 13, so that a hole 33 formed in the base body 13 and a hole 35 formed in the sliding body 15 match up, allowing the insertion of a locking means of the padlock type or the like (FIG. 1) to prevent the opening of the lock, which occurs by sliding the sliding body with respect to the base body, extracting it partially and allowing the arms 19 to join by virtue of the action of the shaped walls 27 on the arms.
  • a locking means of the padlock type or the like FIG. 1
  • the operation of the lock according to the invention is simple and effective. For example, if one wishes to lock a switch 5 in the open position, shown in FIGS. 1 and 8, it is sufficient to place the lock in the open position (FIGS. 2 and 4), making the sliding body 15 slide backward with respect to the fixed body 13, and then insert the tip 31 in front of the recess 7 of the handle 3. By moving the sliding body 15 into the retracted or closed position (FIGS. 3, 5, 6 and 7), the hook-shaped ends 21 are made to protrude and enter the lateral holes 11 formed in the body of the switch. A padlock 37 or the like, inserted in the holes 33 and 35 of the lock, prevents the sliding of the sliding body 15 with respect to the base body 13 and therefore the extraction of the lock and accordingly prevents unauthorized actuation of the switch.
  • the invention achieves the intended aim and object, a safety lock for electrical devices, particularly handle electrical switches, having been provided which allows to lock the switch in a chosen position with an optional key-operated means.
  • the materials used, as well as the dimensions, may of course be any according to the requirements and the state of the art.
