Definitions

  • This invention relates to a mechanical control device for an electric switch.
  • a problem to be solved with electric systems is sometimes that of linking the set/release functions of an electric switch to the positions of some ancillary equipment; for instance, the ability to set the switch may be subordinate to an electric plug being plugged in, a door being shut, a handle moved to a certain position, etc.
  • a frequently occurring problem is that of linking the position of some ancillary equipment to the set/released condition of a switch; for instance, with the switch in the set position, it may be necessary to prevent mechanically an electric plug from being plugged in/out, a door from being opened, a handle from being moved, etc.
  • the object that underlies this invention is to provide a mechanical control device for an electric switch, which can solve the above problems in a consistent manner with the requirement for exchangeability of today's modular systems.
  • a mechanical control device for an electric switch specifically an automatic electric switch of modular design having a front-mounted bistable set/release lever and a side-mounted setting inhibit/assent slider accessible through a slot
  • a mechanical control device for an electric switch specifically an automatic electric switch of modular design having a front-mounted bistable set/release lever and a side-mounted setting inhibit/assent slider accessible through a slot
  • a mechanical control device for an electric switch specifically an automatic electric switch of modular design having a front-mounted bistable set/release lever and a side-mounted setting inhibit/assent slider accessible through a slot
  • a mechanical control device for an electric switch specifically an automatic electric switch of modular design having a front-mounted bistable set/release lever and a side-mounted setting inhibit/assent slider accessible through a slot
  • a mechanical control device for an electric switch specifically an automatic electric switch of modular design having a front-mounted bistable set/release lever and a side-mounted setting inhibit/assent slider accessible through a slot
  • a release member within said housing provided with
  • Such a device can achieve the object outlined hereinabove in that it contains, within a modular design structure similar to that of the switch, elements which can function in combination as a mechanical interface between plural ancillary mechanical members (such as plugs, doors, handles, etc.) and the switch to be controlled.
  • ancillary mechanical members such as plugs, doors, handles, etc.
  • the device includes a pushbutton projecting forwardly from the housing and being associated mechanically with the pressure member such that the pressure member will occupy its working position as the pushbutton is held depressed.
  • the switch cannot be set because its side slider will be held in the inhibit position by the peg of the release member.
  • Said pushbutton is suited, in particular, to control the positioning of a door: the door will only be pushing in the pushbutton when closed to thereby enable the switch to be set.
  • this device includes two separate pressure members, arranged to act separately on the release member. In this way, the ability to set the switch can be interlocked with the positions of two different mechanical members.
  • This device also includes, to advantage, an actuator movable in a guided fashion within the housing between a home or rest position and a working or operative position, by operation of external mechanical members, a front-mounted bistable lever on the housing similar to that on the switch and associated rigidly with the last-mentioned lever by means of a crosspiece, and mechanical linkage means within the housing, between the actuator and the bistable lever, whereby the actuator will either occupy its home position or its working position according to whether the bistable lever of the switch is in the set or the release position.
  • an actuator movable in a guided fashion within the housing between a home or rest position and a working or operative position, by operation of external mechanical members
  • a front-mounted bistable lever on the housing similar to that on the switch and associated rigidly with the last-mentioned lever by means of a crosspiece
  • mechanical linkage means within the housing, between the actuator and the bistable lever, whereby the actuator will either occupy its home position or its working position according to whether the bistable lever of the switch
  • Figure 1 is a side view of a device according to the invention, with a side wall removed to expose its interior;
  • Figure 2 is a perspective view of the device in Figure 1, shown combined with a modular design automatic switch.
  • the switch I is a modular design, automatic electric switch having a front-mounted, bistable set/release lever L and a side-mounted, setting inhibit/assent slider (not shown in the drawings) which is accessible through a slot A.
  • the device 1 comprises a housing 3 having similar shape and dimensions to the switch I.
  • the housing 3 has a recess 4 on its rear for attachment to a mounting bracket in a manner known per se.
  • the device 1 also comprises, mounted within the housing 3, a release member 5 which has freedom of movement between a rest or home position (shown in full lines, Figure 1) and a working or operative position (shown in dash lines, Figure 1); the release member 5 comprises preferably a lever 6 pivoted on the housing 3 by means of a pivot 7.
  • the release member 5 is provided with a peg 8, mounted on the remote end of the lever 6 from the pivot 7 to jut out sideways; the peg 8 protrudes sideways out of the housing 3 through a slot 15.
  • the slot 15 would be facing the corresponding slot in the switch I through which the peg 8 engages with the side-mounted, switch setting inhibit/assent slider; specifically, with the release member 5 in its home position, the slider will be in the position inhibiting the setting of the switch I, whereas with the release member 5 in its working position, the slider will be in the position of assent to the setting of the switch I.
  • the device 1 comprises at least one pressure member inside the housing 3, preferably two pressure members 20 and 21, independent of each other.
  • Each of these members is movable in a guided fashion within the housing 3 from a home or rest position (shown in full lines, Figure 1) to a working or operative position (shown in dash lines, Figure 1) against the bias of respective springs 22 and 23; when in the home position, each pressure member 20 and 21 holds, independently of the other, the release member 5 in its home position (which, as mentioned, reflects in disability to set the switch I), whereas in the working position, each of the pressure members 20 and 21 allows the release member 5 to move into its working position (which, as mentioned, reflects in assent to the setting of the switch I).
  • the pressure member 20 comprises two arms 24 and 26 so made rigid together as to form a crank lever pivoted on the housing 3 by means of a pivot 28.
  • the arm 26 is in contact engagement with a branch 30 of the lever 6 of the release member 5; the arm 24 is arranged to push the spring 22 against a seat 32 formed in the housing 3.
  • a member (not shown) to be operated from without the housing 3 to drive the pressure member by pushing the arm 24 against the spring 22; this member may vary contingent on individual requirements: as an example, it may be a rotary shaft or a slider.
  • the pressure member 21 comprises two arms 25 and 27 made unitary with each other into a crank lever pivoted on the housing 3 by means of a pivot 29.
  • the arm 27 is in contact engagement with a branch 31 of the lever 6 of the release member 5; the arm 25 engages in link-motion relationship with a pushbutton 40 which fits slidably in a respective seat 41 formed in the housing 3, on the front portion thereof, such that the pushbutton 40 will project from the housing 3.
  • the spring 23 is received at the bottom of the seat 41 and will be compressed on depressing the pushbutton 40.
  • the device 1 further comprises an actuator 50, in the form of a slide movable in a guided fashion within a respective seat 51 formed in the housing 3, between home and working positions as external mechanical members (not shown in the drawings) are operated which may be, for example, a latch mechanism for locking an electric plug in a tap.
  • actuator 50 in the form of a slide movable in a guided fashion within a respective seat 51 formed in the housing 3, between home and working positions as external mechanical members (not shown in the drawings) are operated which may be, for example, a latch mechanism for locking an electric plug in a tap.
  • a bistable lever 53 similar to the lever L of the switch I, is provided on the front of the housing 3; the lever 53 is mounted on a drum 54 journalled within the housing 3 and rigidly associated with the lever L of the switch I by means of a crosspiece 55.
  • a mechanical linkage arrangement whereby the actuator 50 will either occupy its home position or working position, according to whether the bistable lever L of the switch I was in its set or release position.
  • This arrangement comprises a rocker arm 56 and a connecting rod 58; the rocker arm 56 is pivoted on the housing 3 by means of a center pivot 57, and engages on the one side with the actuator (a in link-motion relationship, and is pivoted on the other side to the connecting rod 58; the connecting rod 58, besides being pivoted to the rocker arm 56, is connected pivotally to the drum 54 as well, on the remote end thereof from the lever 53.
  • This device 1 operates as follows.
  • the components of the device 1 will occupy their respective home positions shown in full lines in Figure 1.
  • the springs 22 and 23 are urging the pressure members 20 and 21 to so act on the release member 5 as to hold it in its home position; as a result, the peg 8 will hold the side-mounted, switch I setting inhibit/assent slider in the inhibit position.
  • the actuator 50 will also occupy its home position (which corresponds with the positioning of the external members driven by the actuator sought under the rest condition).
  • pressure member 20 or 21, e.g. member 20 is acted upon (by performing the action contemplated for that pressure member, such as the plugging in of an electric plug), the pressure member 20 shall move to its working position, indicated by broken lines in Figure 1; however, this would not yet enable the switch I to be set because the release member 5 is still held in the home position by the other pressure member 21, thereby the side slider of the switch I is still in the inhibit position.
  • the modular design housing 3 affords utmost simplicity of installation in modular electric systems, while not only retaining all the advantages of modularity for the system, but also transferring such advantages to the mechanical control function; in particular, while the device 1 described and illustrated by way of example in the foregoing as equipped with two pressure members and one actuator, contingent on specific demands, a mechanical control device may be employed which includes a different number of pressure members and/or actuators.
  • a device of this type can be readily replaced either on the occurrence of damages or in the event that changed requirements for the electric system call for a more complex device.
