Description
The invention relates to apparatus for attachment to wall-mounted toggle switches, generally light switches, which allows such switches to be operated by toddlers who would otherwise not be tall enough to reach a switch. Accordingly, the invention provides an adapter for attachment to a wall-mounted switch which includes an operating rod adapted to extend downwardly from the switch to a level at which it can be manipulated by a toddler.
Statement of the Prior Art
Applicant is aware of the following U.S. patents pertaining to light switch adapters and the like. U.S. Pat. Nos:
2,493,581; 2,775,674; 3,004,128; 3,839,615; 3,892,935.
While the above patents show different forms of light switch adapters with downwardly extending operating means, the structures tend to be somewhat complex in design and/or obtrusive in their projection from a wall surface. The present invention has as an object the provision of an adapter for wall switches which is of simplified form, employing a minimum number of parts, which may be economically manufactured by readily available means, which is simple to install, and unobtrusive in use.
Summary of the Invention
The invention provides, at least in one embodiment thereof, an adapter for a wall-mounted toggle switch for enabling the switch to be operated by a toddler, the adapter comprising an adapter cover plate forming a replacement for the existing switch cover plate, the adapter cover plate having an elongate internal slot extending from a bottom edge of the adapter cover plate at least part way up the cover plate, an elongate operating rod having an upper portion slidingly received in the slot for guided lengthwise movement in the slot, aligned openings in a rear wall of the adapter cover plate, an upper end of the operating rod, and a front wall of the cover plate, the opening in the rear wall of the cover plate being adapted to fit around the switch boss with the switch projecting through the openings in the operating rod and front wall of the cover plate, and a further opening formed through the adapter cover plate above the slot to receive a screw for attaching the adapter cover plate to a screw hole of the switch mounting plate in a manner securing the rod on the switch with the lower part of the rod extending below the cover plate and with the cover plate being laterally stabilized by the interfitting of said opening in the rear wall thereof around the switch boss.
Adapters in accordance with the invention may thus comprise a minimum of parts, notably an operating rod, an adapter cover plate, and a single screw, and the rod and adapter cover plate may be readily manufactured by molding each of these in plastic, for example. The adapter may be easily installed, simply by removing the existing cover plate from a wall switch, inserting the operating rod in the slot of the adapter cover plate, suspending the assembled rod and cover plate from the switch, and securing the assembly in place with a single screw. The construction of the adapter cover plate and operating rod allows for flush mounting against the wall to provide an unobtrusive construction, and the cover plate may be molded in a diversity of attractive designs and/or include personalized surface embellishments of a child-pleasing appearance.
The invention further provides a light switch adaptor for toddlers comprising a replacement switch cover plate, a switch operating rod associated with the cover plate for projecting to a level below the switch where it can be moved up and down by an infant to operate the switch, and a locking slide associated with the cover plate for operation by an adult selectively to prevent an infant moving the rod up and down as aforesaid.
These together with other objects and advantages which will become subsequently apparent reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming a part hereof, wherein like numerals refer to like parts throughout.

Description of the Preferred Embodiments
FIGS. 1 to 6 of the drawings illustrate a first preferred form of adapter for a wall-mounted light switch enabling the switch to be operated by a toddler, and comprising an adapter cover plate 10 (FIG. 5) and an operating rod 12 (FIG. 6) each of which may conveniently be a plastic molding.
Operating rod 12 may be about 8 inches to 12 inches in length with a thickness of about 1/16 inch. The rod may have a handle portion 14 at its lower end and a head 16 at its upper end formed with a rectangular opening 18 for hooking the rod over and suspending it from a wall-mounted light switch 20, as will be described.
Adapter cover pate 10 may have outer dimensions substantially conforming to those of a standard light switch cover plate, and a thickness of about 5/16 inch. The cover plate (FIG. 5) is formed with an internal elongate slot 24 extending from the lower edge 26 of the cover plate part way up toward the upper edge 28. The depth of the slot is sufficient to accommodate the thickness of rod 12 (e.g. the slot depth may be about 0.09 inch) and its width conforms substantially to the width of head 16 so as to form a guideway for the rod. The slot thereby defines a cover plate rear wall 22 and a front wall 23. Cover plate 10 is further provided with a first rectangular opening 30 in rear wall 22, opening 30 communicating with the upper end of slot 24, and a second somewhat smaller rectangular opening 31 in front wall 23 aligned with opening 30. A further opening 32 is formed through the cover plate above the slot to receive an attachment screw 34 forming a third element of the adapter. Screw 34 may, for example, be a 6-32.times.5/8" screw.
The adapter is suitable for attachment to a standard wall-mounted switch fitting wherein switch toggle 20 projecting from a rectangular boss 21 is carried on a standard metal mounting plate 36 (FIG. 3) in a wall receptacle 38. A standard mounting plate 36 of this nature generally has upper and lower screw holes 40, 42 to which a standard cover plate (not shown) is secured. To install the adapter, it is merely necessary to remove the standard cover plate from the fitting, insert rod 12 into slot 24, suspend the assembly on switch 20, through suitable alignment of openings 30, 18 and 31, and secure the adapter cover plate 10 in position using only the single screw 34 threaded into upper screw hole 40 of the mounting plate 36. The opening 30 is dimensioned to fit snugly over switch boss 21 so as to laterally stabilize the assembly though only a single secured screw is used.
The design of the adapter allows the cover plate 10 to fit flush against the wall 44 (FIG. 3) with operating rod 12 extending downwardly is close proximity to the wall to a position where it can be reached by a toddler to operate the switch by raising and lowering handle portion 14 of the rod. The switch can also be operated directly in the usual manner.
As shown in FIG. 6, the operating rod may have a further opening 19 at the handle end which may be of a different size opening 18 for use with different size switches and, as shown in FIG. 7, the rod 12a may have a uniform width throughout its length. The modified fitting illustrated in FIG. 8 is of similar construction to that described above except that cover plate 10a is molded to simulate an owl. Clearly the cover plate can be formed in other decorative child-pleasing designs. In a further modification (not illustrated) rear wall 22 of the cover plate is omitted and stabilizing tabs are provided behind slot 24 to embrace opposite sides of the switch boss.
FIGS. 9-12 show yet another form of adaptor in accordance with the invention which incorporates a locking device operable by an adult selectively to prevent an infant from actuating the light switch. In this embodiment, adaptor cover plate 10b is of like form to those of the previous embodiments insofar as the provision of slot 24 and operating rod 12b are concerned. In this case, however, the cover plate includes a transverse slot 50 at the top of slot 24 with a locking slide 52 received in slot 50 (after insertion of slide 52 the ends of the slot may be closed by glued-in or like inserts 54, 56 or the like). Slide 52 has a pair of lobes 58, 60 with a gap 62 therebetween and operating tabs 64, 66 at its ends, one or other of which projects from one or other side of the cover plate dependent on the position of the slide. When the slide is in its right-hand position (FIG. 9), gap 62 is centralized over the top of operating rod 12b allowing an infact to raise the rod to actuate switch 20 as in the previous embodiments. When, however, slide 52 is shifted to its left-hand position by pressing tab 66 inwardly (FIG. 11), lobe 60 forms a locking shoulder for the top of rod 12b preventing an infant from raising the rod to actuate the switch.
Additionally, in the embodiment shown in FIGS. 9-12, cover plate 10b is provided with openings 68, 70 respectively, in the front and rear walls 23, 22 for a second mounting screw 72 fitting in the lower screw hole 42 of mounting plate 36. The provision of the seond screw 72 is to meet the requirements of certain jurisdictions which require the use of two such screws. Opening 68 is large enough to permit passage of the screw head, and rod 12b is likewise provided with an elongate slot 74 providing clearace for the screw head as the operating rod is raised and lowered.
It will be appreciated from the foregoing that adapters in accordance with the invention are of simplified manufacture and installation, involving a minimum of parts and installation procedures. When installed, the flush mounting facility of the adapter provides minimum protrusion compared with a standard switch cover plate. The device is reliable in operation and the design of the rod and cover plate wherein the cover plate slot forms a guideway for the rod allows for close working tolerances between these parts limiting side-to-side movement of the rod and minimizing breakages. Additionally, if required (e.g. when a toddler grows sufficiently to reach a standard light switch) the rod may be removed from the adapter and the cover plate used on its own.
The foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.
