There are many instances where it is desirable to be able to operate the conventional wall switch controlling a part of the electrical wiring built into a residence or commercial building from a point distant or remote from the switch. One example is the case of an invalid confined to bed who could not otherwise operate the wall switch which may control a light in the room or an appliance. Therefore an object of the present invention is to provide a novel, portable control means or device for operating a wall switch from a remote point.

A further object is to provide a novel device for operating a conventional electric wall switch which can be readily attached directly to the switch box over the cover plate by means of the cover plate retainer screws.

Another object is to provide a device of the type indicated which attaches directly to the switch box and which receives the switch lever within a novel movable bracket or cage together with electromagnetic means or a motor associated with the cage for moving it controllable from a remote location.

By way of summary, it is an object to provide a device which attaches directly to the conventional wall switch and receives the switch lever and employs electromagnetic units for operating the lever in conjunction with remote switch means for controlling the electromagnetic means and which has means for connecting the device to a source of electric current. These and other objects will be apparent from the drawing and the following description.

' Referring to the drawing:

FIG. 2 is a front elevational view of the device that mounts on the wall switch with the front wall broken away, but on a larger scale than FIG. 1;

FIG. 5 is an inverted plan view on line 55 of FIG. 2;

FIG. 6 is a wiring diagram; and

FIG. 7 is a diagrammatic view of an alternative form of the invention.

More particularly describing the invention, in FIG. 1, a device 11 embodying the invention is shown mounted on a conventional electric wall switch 12 in the wall 13 of a building. The device is shown connected to an electric service outlet 14 by a two-wire cord 15. A remote control switch unit 16 is connected to the device 11 by a cable 17.

Referring now to FIGS. 2-5, the device 11 comprises generally a rectangular box-like casing which is preferably made of metal having a rear wall 20,

side walls

21 and 22, and a lower end wall 23.

An L-shaped cover provides a front wall 24 and an upper end wall 25 to enclose the casing, the cover being secured by a screw 26 in a flange 27 of the rear wall and by a screw 28 in a flange 29 at the lower edge of wall 24.

The rear wall is formed with a large opening 30 to receive freely the switch lever 31 of the conventional electric wall switch 12. The rear wall is also provided with two vertically spaced holes 33, each of which has an enlarged portion 33a of a size large enough to pass the head of the screw 35 which normally holds the switch cover plate 36 to the switch box and a narrow portion 33b wide enough to accommodate the shank of the screw. With this construction the casing may be readily mounted upon and in front of the cover plate by means of the regulation screws 35 that hold the cover plate 36 in place.

Although it is not essential, plastic guard tubes 37 may be mounted in the front wall 24 and extend rear wardly toward the rear wall 20 terminating short thereof to enable safe adjustment and manipulation of the screws 35 with a screwdriver when the device is being installed or removed.

Within the casing I provide two vertically spaced solenoids, designated 38 and 39, these having coils 38 and 39', respectively, receiving

armatures

40 and 41, respectively. A cage 43 is mounted on and rigidly connects the armatures. This includes a bar 44 which has its ends received in slots 46 in the ends of the armatures and held by pins 47. The cage includes a U-shaped bracket 50 attached, as by a rivet 51, to the bar 44 and extending laterally thereof, this bracket being adapted to receive the switch lever 31. The outer ends of the two legs of the U-shaped lever are turned outwardly terminating in flanges 52 and preferably each of these is provided with a roller 53 adapted to run against the rear wall of the casing. The two flanges are also connected adjacent the cover by a glider plate 55, riveted in place at 56, which may be of plastic and which serves to maintain the position of the cage with respect to the parts and prevent rotation of it away from the rear wall, the glider being adapted to run against the cover in the event of any force tending to displace it in that direction.

The solenoids are oppositely acting so that when one is energized it will move the cage and thus the switch lever in one direction and when the other is energized it will move the cage and switch lever in the opposite direction. In order to control the device I provide the switch unit 16. This includes two single-pole, singlethrow, normally off, push button switches 58 which are connected into the circuit (see FIG. 6) so that either solenoid can be energized at a time. The cable 17 connecting the switch unit to the device 1 1 preferably contains a ground wire 60 so that when it is plugged into socket 61 of the casing, the switch unit will be grounded. In this connection it will be apparent that the mounting of the casing of the main unit on the screws 35 of the switch effectively grounds the entire device. I then provide the separate cord 15 which plugs into a jack at 63 for connecting the circuit to the nearest electric outlet.

While I have shown the device 11 connected to a remote source of electric energy by the electric cord 15 I contemplate that the device, if it is to remain in place for a long period of time, might be wired into the house wiring circuit at the switch box. Also, I contemplate that battery-operated direct current solenoids might be used in place of those shown. Altemately, I may employ a battery-operated low voltage d.c. motor (FIG. 7) with a rack and pinion drive 71 for the cage 43 which can be attached thereto. Batteries 73 can be connected selectively to either side of the motor by any suitable switching means such as that shown at 74. This is merely exemplary as is the switch means shown in FIG. 6. For example, the switch of such figure might be replaced by a single-pole, double-throw, momentary contact switch with a center off position.
