Definitions

  • a switch lock assembly comprising one tumbler lock unit, a plurality of switches and a key. Said switches are supported rearward of the outer barrel of said tumbler lock unit, and said key is provided with a rearwardly elongated portion which projects rearward of the outer barrel. Said elongated portion has a longitudinal operating edge which can operate at least one actuator of said switches when the key is rotated.
  • the present switch lock assembly can control a lot of apparatuses and the like.
  • SWITCH LOCK ASSEMBLY The present invention relates to a switch lock assembly wherein an actuator of a switch is driven by a cam attached to a rotatable lock cylinder of a tumbler lock unit, so that those who do not have a key can not operate the switch.
  • such a switch lock assembly has only one switch, so that one apparatus alone can be controlled. Therefore, if there are a number of apparatuses to be controlled, it is necessary to provide the corresponding number of switch lock assemblies. It is impossible to obtain a simplified controller panel, because a great part of the front of the controller panel are occufile with the heads of numerous tumbler lock units. As each switch lock assembly includes one tumbler lock unit, such a multiple controller requires a number of tumbler lock units which are not inexpensive, so that it is very difficult to decrease the cost of production.
  • Another object of the invention is to simplify the front face of a multiple controller panel.
  • the other object of the invention is to decrease the cost of production of such a controller.
  • FIG. 1 is a front elevational view of a switch lock assembly constructed in accordance with the principle of the present invention
  • FIG. 2 is a rear elevational view of the assembly
  • FIG. 3 is a rear elevational view of the assembly when a switch is removed
  • FIG. 4 is a side elevational view of the assembly shown in FIG. 1 parts being shown in section;
  • FIGS. 5, 6 and 7 are side elevational views of different keys employed in the assembly.
  • the tumbler lock unit 10 is composed of an outer stationary barrel l3 and an inner rotatable lock cylinder 12.
  • the lock cylinder 12 has three locking pins 1 1 which can be driven to an inoperative position by the operating edge 32 of the key when the key are inserted into the key hole 14 of the lock cylinder 12.
  • An attaching member 23 is fixed to the rear end face of the outer barrel 13 by two set screws 22.
  • switches 20a, 20b, 20c and 20d are attached to said attaching member 23 by means of two screw bolts 25 which are threaded into two tapped holes 24 formed in the attaching member 23.
  • the respective actuators 21a, 21b, 21c and 21d of said switches are located in alignment on the same line parallel to the axis of the lock cylinder 12.
  • the respective leads 26a, 26b, 26c and 26a may be connected to apparatuses A, B, C and D which are unshown in the drawings.
  • This tumbler lock unit 10 are attached to a controller panel 1 by two nuts 16 and 18.
  • the reference packing respectively.
  • the key 30- is provided with a rearwordly elongated portion 31 which can project rearward of the rear end-face of' the lock cylinder 12.
  • the elongated portion 31 has a longitudinal operating edge which can drive at least one actuator 21a, 21b, 210, 2 Id to an operative position when the key 30 is rotated in a clockwise direction throughout an angle of Referring to FIG. 5A in particular, this key can drive all of the actuators 21a, 21b, 21c and 21d, because its operating edge is formed continuously all over the length. Therefore, those who intend to operate all of the apparatuses A, B, C and D should use the key 30 shown in FIG. 5.
  • the key 30 can drive two actuators, that is to say, actuators 21a and 210, because the elongated portion 31 is provided with two recesses 33b and 33d in the longitudinal operating edge, which allow actuators 21b and 21d to remain at an inoperative position.
  • the key 30 shown in FIG. 7 should be used by those who wish to operate two apparatuses A and C.
  • the switch lock assembly constructed in accordance with the present invention can control a lot of apparatuses and the like, as it includes a plurality of switches 20a, 20b which are operated solely or simultaneously by the single tumbler lock unit 10. It is, therefore, possible to simplify the front face of a multiple controller panel considerably.
  • a switch lock assembly comprising one tumbler lock unit, a plurality of switches, said tumbler lock unit having an outer stationary barrel and an inner rotatable tumbler-equipped lock cylinder, and a key to be inserted through said lock cylinder, said switches being supported rearward of the outer barrel, actuators of ating edge which drives at least one actuator to an operative position when the key is rotating said lock cylindef;
