A TTORNE VS PLURAL MODULE CIRCUIT SIGNALING SYSTEM This invention relates to signaling systems and particularly to switching modules utilized in such systems.

In the handling of rooms and the like in hotels, motels, and similar institutions, it is'desirable that the status of the room, namely, occupied, unoccupied, ready for occupancy, and the like, be readily known to a person handling the incoming and outgoing guests.

Accordingly, among the objects of the present invention are to provide a signaling system utilizing a novel switch module which is relatively simple, low in cost, easy to maintain, and effectively operates to indicate the status of the room.

SUMMARY A signaling system including a plurality of switching modules which include a manually operated member adapted to be selectively actuated to one of four positions and a remotely operated switch which, upon actuation, from a remote position changes the position of the manually operated member. Each switching module further includes indicia means in the form of lightbulbs.

DESCRIPTION OF THE DRAWINGS FIG. I is a part sectional elevational view of a switch module embodying the invention.

FIG. 2 is a part sectional rear elevational view of the same.

FIGS. 3--6 are partly diagrammatic views showing portions of the parts in different operative positions.

FIG. 7 is a schematic wiring diagram of the signaling system.

FIG. 8 is a fragmentary part sectional view of a modified form of switch module.

FIG. 9 is a front elevational view of an array of modules.

DESCRIPTION Referring to FIG. 7, the signaling system embodying the invention comprises the use of a module 10 and associated circuit for each of the rooms in the system. Each circuit includes a switch module 10 that is connected to a remote switch II in the room and indicia or lights 12 in the housekeepers area.

Referring to FIGS. 1 and 2, each switch module I comprises a frame II that is generally U-shaped in cross section and made of metal. The frame supports a block I2 at one end which, in turn, supports a plurality of leaf contacts 13, I4, 15, I6. As shown diagrammatically in FIG. 4, contacts 14 and I are normally in contact with one another.

Frame 11 further supports a frame member 17 on which an electromagnet 18 is supported. In addition, a latch I9 is pivoted to one end of the frame member I7 and yieldingly urged counterclockwise, as viewed in FIG. I, by a spring 20 extending between one end of the latch and a tab 21 struck outwardly from the frame member 17.

As shown in FIG. 2, a manually operated lever 22 is pivoted by a stud 23 in an elongated slot 24 in the frame II. A tension spring 25 is connected to the lower end of the lever 22 and to the frame extends between the end of lever 22 and the frame to yieldingly urge the lever downwardly as viewed in FIG. 2. The upper end of the lever is twisted as at 25 to form a gripping portion that extends beyond the frame I]. The frame II further includes a cutaway portion 26 defining spaced

detents

27, 28 which are engaged by a detent pin 29 on the lever. A protective cap 30 urges the lever against the frame.

By this arrangement, the lever 22 can be manually operated to one of two detent positions A and B and momentarily moved to two other positions C and D beyond detent positions A and B.

The lever 22 includes an operating member or pin 31 having an insulating sleeve 31a and extends inwardly between the

contacts

14 and 15. When the lever is in position A, contact I5 is held out of engagement with contact 14, as shown in FIG. 3. When the lever 22 is moved to position C, contact 14 engages contact I3. In this position, a latch shoulder 32 in latch I9 engages the upper end of the contact 14 to maintain it in contact with contact 13 as shown in FIG. 5.

When the lever 22 is shifted momentary to position D, contact I5 is moved into momentary engagement with contact 16 while the upper end of the contact I5 lifts the latch I9 out of engagement with the contact 14.

In practice, the positions A, B, C and D represent the following status of the room:

Position A-Occupied Position B-Checked out Position C-Latching motion necessary to indicate that the room is checked out Position D-Reset to position A As shown in FIG. 1, indicia means in the form of two

lightbulbs

33, 34 are mounted on the upper end of the frame and a jewel or translucent cap 35 is provided over the bulb. Referring to FIG. 9, a plurality of switch modules 10 corresponding to the number of rooms are mounted in a panel. Each cap has indicia 36 to identify the room.

Referring to FIG. 7, which is a schematic diagram the contacts and bulbs are electrically connected with the switch II in such a manner that momentary closing of the switch II will energize the solenoid 18 to disengage the latch 19. Thus, the housekeeper after making the room can actuate the module to return the contact to the position corresponding to availability for occupancy and energize bulb 34.'Lightbulbs 37, 38 can be provided at a remote point in the housekeepers area 12 to indicate the status of the rooms to the housekeeper.

Specifically, when

contacts

14, 15 are in engagement, a circuit is completed to lights 33, 37, and when

contacts

13, 14 are in engagement, a circuit is completed to lights 34, 38.

In the form of the invention shown in FIG. 8, the switch module includes contacts I3, l4, l5 and 16' as in the previous form of the invention. However, the latching structure differs in that a latch 19' is pivoted to the upper end of contact I4' and is adapted to engage a portion of the frame member II. The latch 19' is yieldingly urged downwardly by a leaf spring 20'. A solenoid I8 is adapted to be energized to cause its plunger 18a to move upwardly to disengage the latch I9. Otherwise, the system operates in the same manner as the previously described system.
