ELECTRIC SWITCH OPERATING DEVICE 7 Filed June 15, 1948 6 [b 6 @0 JAcaa Z Patented Oct. 16, 1951 UNITED STATES PATENT OFFICE The present invention relates generally to electric switches and is more particularly directed to an improved decorative switch placque and switch operator adapted to be used in place of the usual wall type switch plate or escutcheon.
This invention in general constitutes an improvement upon the electric switch manipulating vmeans disclosed in my prior Patent 2,172,731, issued September 12, 1939, and accordingly embodies the desirable features provided thereby together with certain new and additional advantages to be hereinafter more fully set forth.
As described in detail in my prior patent, Number 2,172,731, referred to above, the usual snap-action wall switch is intended to provide a rapid make-and-break in its associated electrical circuit but in spite of this fact it has been observed that sparking sometimes occurs of sufiicient intensity to pass through the usual toggle slot thereby shocking or burning the person operating the switch. The switch manipulating means illustrated in my said prior patent accordingly was developed to overcome this difiiculty and to that end provided a rather large handle member adapted to cooperate with the usual switch toggle arm or lever but being of such dimensions as to completely overlie the toggle slot. By reason of this construction it was also found that the external appearance of the switch could be considerably enhanced by providing ornamental decorations upon the exposed portions thereof and furthermore, the switch was rendered more easily operable in the dark.
While as previously indicated the present invention contemplates the above enumerated advantagesprovided by the improved construction disclosed by my prior patent, Number 2,172,731, the present invention further aims to provide a switch operating device embodying additional improvements of a type which both render the switch more satisfactory in operation and also lend themselves more readily to the rapid largescale production of such devices upon a mass or volume basis.
Accordingly, the principal object of the present invention is to provide an improved switch operating device of the type described embodying substantially a minimum number of working parts and being otherwise of relatively simplified construction thereby lending itself more readily to the purposes of large-scale production.
Another and more specific object of the invention is to provide an improved switch operating device of the type described embodying a more rigid construction and especially overcoming any 4 Claims. (Cl. 200172) jecting from the switch box 22.
tendency of the switch operating member to rotate relative to its base or wall plate.
The foregoing as well as numerous other objects and advantages of the present invention together with a clearer understanding of the precise nature thereof will become more readily apparent to one skilled in the art from a consideration of the following detailed specification taken in conjunction with the accompanying figures of drawing illustrating a preferred embodiment thereof, wherein:
Figure 1 is a front elevational view of an improved switch operating device in accordance with the present invention;
Figure 2 is a rear elevational view of the switch operating device of Figure l;
Figure 3 is a longitudinal cross-sectional view through the device taken substantially along the line 33 of Figure 1;
Figure 4 is a transverse cross-sectional view through the device taken substantially along the line 44 of Figure 1; and
Figure 5 is an exploded perspective view particularly illustrating the relationship between the three major elements of the device.
Referring ,now in somewhat more detail to the various figures of the drawing and in particular to Figure 1 thereof, there is disclosed an improved switch operating device having a generally fiat rectangular plate or base 10 on which is slidably mounted an oval shaped switch operating member [2. The operating member I2 is appreciably larger than the usual switch toggle lever and is preferably provided with a suitably decorated outer surface which may take any of a number of forms and which is designated generally by reference numeral I l. Both the base l0 and the switch operating member 12 are preferably formed entirely of a molded plastic 24 constituting an open inner cavity for the purpose of receiving the toggle arm or lever 26 pro- The base 10 is held in position on the wall in any convenient 3 manner as by means of screws or bolts 28 extending through countersunk apertures or holes 30 formed along the longitudinal center line of the base and threadedly engaged within suitable holes formed in the usual longitudinal mounting bracket 32 which in turn is secured as at 34 to the front wall of the switch housing 22.
The switch operating member I2 is arranged for limited sliding movement in a longitudinal direction along the front surface of the base I and to this end the base is provided with a relatively large rectangular aperture 36 in its central portion through which project lugs 38 formed at the opposite sides of the cavity 24 in the member I2 and adapted to abut the upper and lower edges of the aperture 36 to limit the linear movement of the member I2. In order to resiliently retain the member I2 against the outer or front surface of the base I0 there is provided a spring designated generally by reference numeral 40 which is slidable along the rear or inner surface of the base I0 and is preferably rigidly secured to the lugs 38 in any convenient manner as by means of rivets 42 or the like. The spring 40 is of a very special construction as will be hereinafter more fully set forth and it will be noted that this spring overlies the aperture 36 in such manner that the member I2 may be moved between its upper and lower limit positions while being simultaneously resiliently and continuously urged against the front surface of the base I 0.
The inner surface or face of the base I0 as shown particularly in Figures 2 and is provided with intersecting pairs of longitudinal and transverse mold strips 44 and 46, respectively, preferably formed integrally at one side of the base I9 during the molding operation. As shown in these figures the mounting holes which receive the bolts 28 are located in such manner as to project through the upper and lower transverse mold strips 46, respectively, the latter being somewhat enlarged at these locations as indicated by reference numeral 48. It will thus be apparent that by virtue of this construction I have provided for increased strength at the critical mounting points of the assembled device by utilizing portions of the transverse mold strips 46 which at the same time accomplish the additional function of increasing the strength and rigidity of the base ID of the device.
As indicated above, the spring is of very special construction and by referring particularly to Figures 2 and 5 it will be noted that this spring is of unitary construction and is formed in the shape of a generally open rectangle. The main leaf portions 50 at opposite sides of the spring 40 are bent inwardly adjacent their ends as indicated by reference numerals 52 and are then reversely curved in an upward direction at their terminal portions to form smoothly rounded runners 54 adapted for sliding engage ment with the inner surface of the base Ill. Suitable apertures 56 are provided at approximately the midpoints of the leaves 50 for the purpose of receiving the rivets 42 hereinabove referred to which securely hold the spring 40 to the lugs 38 of the operating member I2. The spring 40 likewise includes cross members 58 at each end which are preferably integral and rigid with the leaf portions 50 and are similarly curved to carry out the smoothly rounded contours of the runners 54 so that in overall effect the spring 40 is rectangular in shape with a large central aperture or cut away portion 60.
In assembling the device the operating memher I2 is placed against the outer or front face of the base I 0 with the lugs 38 projecting through the aperture 36 at opposite sides of the latter. The spring 40 is then placed against the rear or inner face of the base I0 and the leaves 50 firmly secured to the lugs 38 by means of the rivets 42 which pass through the apertures 56. It will be particularly noted in Figures 2 and 4 that when the device is thus assembled the spring 40 substantially completely fills the space between the longitudinal mold strips 44 transversely of the base I0 while at the same time providing a substantial amount of unobstructed working space between the transverse mold strips 46 so that the spring 40 and operating member I2 may be freely moved longitudinally of the base ID. This construction is particularly emphasized for the reason that the engagement of the outer longitudinal edges of the spring 40 in slidable abutting relationship with the respective inner edges of the longitudinal mold strips 44 constitutes substantially the sole guiding means for the memher in its linear movement. Thus the mold strips 44 in addition to performing their function of strengthening the base I0 likewise serve as guides for the member I2 and by reason of the unitary construction of the spring 40 and its rigid engagement at two points with the member I2, the latter is substantially prevented from rotating relative to the base I El.
Although the operation of the device will be largely apparent from the foregoing description it may be briefly noted that as shown in Figure 3 the completely assembled device is adapted to be substituted for the usual wall switch plate or escutcheon and is so dimensioned as to conceal the wall cavity 20 when in operative position. Thus it is only necessary to remove the wall switch plate or escutcheon which is usually provided and then by means of the screws or bolts 23 to mount my improved device upon the same bracket 32 in the usual manner. During this mounting or substitution operation the member I2 may be suitably adjusted in such manner that the switch toggle arm or lever 26 will be properly received within the cavity 24. Thereafter as the operating member I2 is moved longitudinally of the base Iii which is now secured to the switch housing or box 22, the toggle arm 25 will be snapped back and forth in the usual manner but without at any time exposing the operator to an open path leading to the electrical contacts or connections of the switch proper.
Throughout the foregoing description an effort has been made to emphasize the simplicity of the present construction by reason of which my improved device is soreadily adapted to the purposes of large-scale mass production. Thus it will be noted that each of the mold strips 44 and 45 serves a dual function in providing for increased rigidity of the base I8 and at the same time serves either to in effect elongate and strengthen the mounting holes 30 or, in the case of the longitudinal strips 44, to guide the linear movement of the switch operating member l2. In like manner the construction of the unitary spring 48 is extremely simple and yet is admirably adapted, in conjunction with the strips 44, to provide the desired straight line motion of the switch operating member I2, As indicated above, each of the members 58 and I2 may be readily formed in a single injection molding or die casting operation while the spring 40 may be mass produced of steel or other material in a number of different ways such as, for example, by means of progressive dies. In like manner the entire device may be rapidly assembled with a minimum amount of labor so that the entire unit may be manufactured and sold at extremely low cost.
Obviously numerous other modifications, alterations, and deviations from the specific structure disclosed herein solely for the purpose of illustration will occur to one skilled in the art and it is to be understood that various changes in size, shape, and materials of construction may be made Without departing from the spirit or scope of the invention.
