C. M. G. DU TEMPLE DE ROUGEMONT ETAL ASSEMBLY MOUNTING AND INTERLOCKING MEANS FOR PLURAL PUSHBUTTON SWITCHES Filed June '7, 1963 United States Patent 3,259,699 ASSEMBLY MOUNTING AND INTERLOCKING MEANS FOR PLURAL PUSHBUTTON SWITCHES 7 Claims. (Cl. 2o0-s This invention relates to electric switching assemblies or multiple electric switches, and in particular to such switches with push-button controls as are used in electrical or electronic appliances for performing the switching of a plurality of circuits. I
It is an object of the present invention to enable, starting from a reducednumber of different switching elements each controlled by an operating element such as a push-button, the formation of more or less complicated, multiple switching assemblies for a great variety of applications.
The invention consists in assembling and attaching on a single supporting bar, any number of switching elements which may incorporate any number of switches actuated by the same push-button and capable of being arranged on the said supporting bar in any desired order or spacing.
The present invention is a switching assembly comprising a plurality of electric switching elements assembled and fixed parallel to each other on a single transverse carrier bar, each of the said switching elements comprising projecting and recessed fixing and locating means, which are identical for all the switching elements and which interlock with fixing and locating elements of substantially complementary form on the carrier bar, the latter incorporating at least one element lOcKing the switching elements on the said carrier bar.
The attaching elements are preferably of the bayonet joint type, and the locking of the switching elements on the supporting bar is obtained by distorting a part of the said bar preferably constituted by a metal channel section.
The invention preferably includes an unlocking device reciprocally releasing the switching elements particularly applicable to a switching assembly such as that described above. Such an arrangement has the purpose of making at least some of the push-buttons dependent on each other in their action: e.g., the actuation of any one button produces the release of the corresponding, linked buttons. In accordance with the invention, the unlocking device preferably comprises a sliding rod or bolt coacting with all of the associated buttons and arranged inside a carrying bar in a space provided between the bottom of the said bar and the face thereof opposite to the switching elements associated therewith.
Embodiments of the present invention will now be described, by way of example, with reference to the accompanying drawings, in which:
FIG. 1 is a perspective view of a switching assembly in accordance with the present invention;
FIG. 2 is an exploded view of a switching assembly before assembly;
FIG. 3 is a detailed, perspective View of the manner of attaching the switch elements on the supporting bar;
FIG. 4 is a plan view of another switching assembly in accordance with the present invention;
FIG. 5 is a partial sectional view perpendicular to the axis of the supporting bar;
FIG. 6 is a partial sectional view of the locking element reciprocally securing the switching elements depending thereon; and,
FIGS. 7 and 8 illustrate the manner of action of the locking element.
The switch assembly shown in FIG. 1 consists of five switching elements 2 to 2 which are each actuated by a push-button 4 to4 with two positions, and which are assembled on a carrier bar 6 consisting of a metal channel section formed in its central webs with holes 7 through which the selector elements 9 of the individual switches can pass.
At one end 8 (FIGS. 2 and 3) the casings of insulating material carrying fixed-terminals 10 of the switches, are provided with projecting bosses 12 which engage and lock by means of a bayonet joint, by a push and lateral sliding motion, in L-shaped notches 14 cut in at least one of the flanges of the section bar 6.
In the preferred form, shown in FIG. 3, bosses 12 and notches'14, 14' are provided on the two, upper and lower faces of the switches and on the two flanges 16, 16 of the section bar.
A shoulder 18, 18 made on the two opposite faces of the insulating casing, bears against the edge of the flanges 16, .16 and positions the switches on the carrier bar.
In FIGS. 1 to 3, the switch elements 2 to 2 are mounted side by side, i.e., the spacing of the notches 14 is equal to the width L of one switch element.
When the last switch 2 has been fitted in place on the carrier bar, all the switches are locked in place against each other by depressing a lug 20 on one of the flanges or at the base of the section bar 6, as indicated by dash lines in FIG. 3.
It will be seen, in FIG. 4, that the spacing between the switch elements 2 to 2 can be made greater than their widths, and the switches individually locked in place by bending down the individual, depressible locking pieces 20, located at the carrier bar adjacent each switch. The spaces thus created between the switches can be arranged to receive accessories such as condensers (capacitors) or resistances (resistors), which are thus located in direct proximity to the switch terminals, thus reducing the length of the necessary connections to a minimum.
It will be clear from the preceding that, using a reduced numberof standard switch elements, it is possible to form switching assemblies of the most complicated and varied character.
The free spaces at the ends of the shortest switch ele- I ments may be arranged to receive coils or the like 21, enabling still further miniaturization of the assembly.
The assembly of such arrangements is simple and rapid since-it is suflicient, when all the switch elements are in place, and the locking lug or lugs have been depressed, to engage the return springs 22 on the parts of the selector elements 9 projecting outside the section bar 6, and to hold these springs in place in the usual manner, by resilient rings 2'4, before fitting in the place the push-buttons 4. Holes 26 made in extensions on the bar 6 enable the switching assemblies according to the invention to be titted in such appliances as radio receivers, television Patented July 5, 1966 .invention, the locking length D (FIG. 3) of the switch elements is made shorter than the depth of the section bar and in the opposing face of the insulating casings of the switches a narrow gap 27 (FIG. is left along the whole bar, which may be arranged to contain a locking rod 28 sliding longitudinally and having holes 30 30 and 30 (FIG. 6) for the passage of the selector elements 9.
If it is required that some of the switches (for instance 2 and 2 in FIG. 2), shall be interdependent, their selectors are provided with notches 32 having a bevelled edge abutment (FIGS. 2, 7 (and 8), which locks on tongues such as 34 34 projecting into openings 30 30 A spring 36, suit-ably attached to the bar 6, tends to push the locking rod 28 against the notches 32, so that (FIG. 7) when one of the buttons corresponding to the selectors 9 or 9 is pressed, the locking rod 28 is pushed in the direction of the arrow 38 (FIG. 6) by the bevel of the corresponding notch, which frees the other selector (FIG. 8) if the latter was in the engaged position. It will thus be seen that pressing a single button unlocks all the other interdependent buttons.
In the case shown in FIGS. 2 :and 6, the switch 2 is independent due to the fact that the corresponding opening 30 of the locking piece 28, does not contain a tongue 34.
In such case, the switch may be equipped with an independent locking system for one or the other of its positions.
