Application June 27, 1946, Serial No. 679,625 Claims. (Cl. 173334.1)
This invention relates to new and useful improvements in electrical outlets, and in particular to the type of outlets adapted to be mounted near the bottom portion of a building partition.
It is one object of this invention to provide an improved electrical outlet which may be utilized to furnish electric power at any point along the baseboard of a building partition.
It is a particular object of the invention to provide an improved electrical outlet which eliminates the necessity of having a great number of individual outlets spaced about the walls of a room, and allows electric power to be drawn at any point or points from the baseboard of the walls of the room.
Another object of the invention is to provide an improved electrical outlet which is simple in structure and economical to manufacture, comprising a minimum number of parts, and which is very flexible in its adaptation to particular installations, as much or as little electric power outlet facilities as desired being available by utilization of various combinations of the invention.
Yet another object of the invention is to provide an improved electrical outlet which simulates the appearance of the normal baseboard and may be joined in sections so as to provide any desirable length of baseboard, and which is constructed in such a manner as to be very safe, the
possibility of a person touching the electric conductor or of a short occurring being substantially eliminated.
A still further object of the invention is to provide an improved electrical outlet of the charcter described which may be installed in the place of the usual baseboard and does not require a special structure in the wall or floor portions of the building in which the device is to be utilized.
A construction designed to carry out the invention will be hereinafter described together with other features of the invention.
The invention will be more readily understood from a reading of the following specification and by reference to the accompanying drawing, wherein an example of the invention is shown, and wherein:
Fig. 1 is a side elevation taken from the rearward side of an electrical outlet constructed in accordance with the invention,
Fig. 2 is a vertical, transverse, sectional view taken intermediate the ends of one of the outlet units.
Fig. 3 is an isometric view of the top mounting bracket,
Fig. 4 is an isometric view of the lower mounting bracket, and
Fig. 5 is a vertical, cross-sectional view taken on the line 55 of Fig. 1.
In the drawings, the numeral 10 designates the lower portion of the usual wall partition as occurring in residential and business structures. A floor ll abuts the wall and extends at right angles in the usual manner, forming a corner in which the usual type of baseboard (not shown) is customarily positioned.
In place of the usual baseboard, applicants electrical outlet device, designated generally by the numeral i2, is positioned so as to perform the functions of the usual baseboard and at the same time provide extensive electrical outlet facilities.
The device or structure 12 includes a top mounting bracket [3 which may be formed by stamping and bending sheet metal or by casting from plastics, or from any other suitable material and by any desirable means. The bracket [3 includes a central, substantially rectangular plate-like portion I4 which is adapted to extend in a vertical plane at right angles to the surface of the wall iii. The plate I4 is formed with an ear IE3 at the upper portion of its rearward edge, the ear I5 extending at right angles to the plate so as to be parallel to the surface of the wall. An opening [6 is provided in the ear [5 to receive a wood screw Il' by which the bracket may be secured to the wall it at the desired location. A second and a third ear l8 and 19, respectively, extend from the lower front edge and the bottom edge 14 and at right angles thereto, the ear l8 being parallel to the wall Ill while the ear I9 is perpendicular thereto. Openings 26 and 2| are provided in the ears I8 and IQ for receiving screws in a manner to be more clearly set out hereinafter.
A bottom mounting bracket 22, formed similarly to the top bracket Hi from metal or other suitable material, is provided for mounting in the corner between the wall It and the floor ll so as to project at right angles therefrom. The
bracket 22 is substantially L-shaped in crosssection, the shorter leg 23 being adapted to engage the surface of the wall in and having an opening M provided therein for receiving a wood screw 25 to secure the bracket in position upon the wall surface. The longer leg of the bracket 26 is arcuate in outline so as to conform to the curvature of the customary shoe mold (not shown) and is provided with an upstanding section 2! contiguous to the arcuate and 28 of the portion 26. The section 2'! is provided with an car 28 at its upper end, said ear extending laterally at right angles to the portion 21 so as to be perpendicular to the wall I0, and a second ear 29 extends laterally from the front edge of the upstanding portion 27 so as to be substantially parallel to the wall surface. The cars 28 and 29 are provided with openings 30 and 3| respectively, for receiving screws to be described hereinafter. It is pointed out, that the horizontal distance between the ear 29 and the leg 23 of the bracket 22 is substantially equal to the horizontal distance between the ears [5 and N3 of the top bracket l3 whereby the ears It; and 29 are in substantial vertical alinement when the top and bottom brackets I2 and 22 aresecured in position upon the surface of the'wall I0.
In installing this improved baseboard outlet, a plurality of the top and bottom brackets are secured to the wall surface at points spaced along the wall and at uniform height above the floor II. The lateral spacing of the brackets depends entirely upon the length of the sections to be mounted thereupon and will be governed thereby.
An elongate stantially rectangular in cross=section is adapted to have its ends positioned between the ears [9 top and bottom brackets so as to be, in contact therewith. The ends of the spacer 3|, are cut away on their top and bottom sides to form pins 32 at each end of the spacer, said pins being equal in width but less in thickness than the body of the spacer itself. The spacer 3! may be formed of wood or plastic or may be of any other suitable composition which has electrical insulating properties, and has secured to its top and bottom sides, elongate, flat, contact strips of metal, such as copper, to provide contacting surfaces. The strips 35 are secured to the spacer by. means of suitable screws 34 countersunk in the surface of the strips so as to present a substantially continuous surface, and have their front edges beveled, as shown in Fig. 2 of the drawings. An additional strip 35, which may be of metal or plastic, as desired, is secured to the front edge or face of the spacer 3! by means of suitable screws 36, countersunk in said strip.
The brackets l3 and 22 are secured to the wall, one above the other, in pairs for mounting the spacers. 3|. The spacers may be of any desirable length but normally, will be about four feet in length so that one pair of brackets would be positioned four feet from another pair and the spacer extend therebetween. Additional sets ofbrackets and spacers may be utilized, as shown in Fig. 1 of the drawings, to give a greater length of outlet space. In this instance, a second pair of brackets I 3 and 22 are mounted next one of the first pair and an additional pair about four feet therefrom. A second spacer extends between these brackets and has its pin 32 at one end abutting the pin 32 of the adjacent spacer.
A pair of rectangular connectors 31', equal in width to, the spacers, are positioned above and below the abutting pins 32, and are equal in length to the combined length of the pins, so as to lie snugly within the cut away portion of the two spacers. Holes 38, in vertical alinement with the holes 2| and so in the ears I9 and 28, are formed in the pins and the. connectors, so that bolts 39 may be passed therethrough and se-.. cured by nuts All. The bolts 39 fasten the spacers to each other and to the brackets, thus provid-. ing a secure mounting for the spacers.
spacer strip of molding 3!, sub- A pair of electrical conductors 4| are connected from a suitable source of electrical power (not shown) to the upper and lower contact strips 33 by engagement beneath one of the screws 3 2 holding said strips, so that the strips become extensions of the conductors 4! and electric power may be drawn therefrom.
It is pointed out, that the upper and lower strips 33 terminate short of the brackets I3 and 22 at either end of the spacer 3| so that shorting of the strips to the bracket is prevented. The space provided between the space and the bracket is considerably greater than the width of the prong of an ordinary electric plug so that shorting through said prong is also prevented.
elongate angular top cover plate 42, being substantially L-shaped in cross-section and having its corner rounded, is adapted to be secured to the ears I8 of the top bracket i3 by means 7 of suitable screws so as to overlie said bracket and have its inner edge abutting the surface of the wall It, while th lower edge terminates at short distance above the strip 35 carried by the spacer 3i, Thus an elongate slot is provided between the. plate 52 and the strip 35. A bottom cover plate it shaped to conform to the outline of the bottom bracket 22 and having its lower portion curved outwardly and downwardly to simulate the normal shoe mold (not shown), is provided to overlie the bottom bracket 22, The upper portion of the plate 44 lies adjacent the ear 29 and is secured thereto by suitable screws, 45 which en a e wi h n the p n n forme in the ear 29. The upper edge of the plate 44 terminates a short distance below the strip 35 so as to provide an elongate slot therebetween, while the lower extremity of the plate abuts the surface of the floor II to provide a neat and ate tractive structure. The lower curved portion of the plate 44 is formed to snugly engage the arouate portion of the bottom bracket, as shown in Fig. 2 of the drawings.
Since the ears {8 and 29 are in substantial vertical alinement with the forward face of the spacer 3i, the vertical portions of the top, and bottom cover plates along with the vertical strip. 35 present a smooth and substantially continuous surface, broken only by the elongate slots above and below said strip. It is pointed out, that the width of the slots is not sufficient to allow the, insertion of a childs finger, or the like, into said slot, so that a safe. structure is provided.
The plates 42 and i i may be formed of metal or plastic or other suitable substance, and are normally equal in length to the spacers 3| although other lengths may be utilized. When. more; than one length of cover plate is used, the ends of the plates abut at the pairs of brackets mounted side by side, as shown in Fig. 1 of the drawings, and a narrow auxiliary plate 46, is provided to coverthis joint. The plate 46 is substantially equal in width to the two pairs of brackets and shaped to conform to the outer surface of the upper and lower plates l2 and di so as to overlie snuglysaid plates. Openings 4? are provided in the plate 46 to receive the screws 43 and 45 to hold said plate and the plates t2, and 4.4 in. place.
Thus, a very flexible structure is provided which may be readily adapted to varying requirements as to the. length of outlet space desired. The spacer-s 3i and plates l2 and 44. may be formed in any desired length, and utilized in any desired multiple of such lengths. Obviously, provision may be made for inside and outside comers in the baseboard portion of a wall surface, and it is not deemed necessary to show such means in the drawings. Also, the outlet may be terminated at any desired point and the usual baseboard continued from that point.
In the use of this improved outlet, the usual two-prong electric plug A is employed, the prongs of the plug being inserted at any desired point within the slots above and below the strip 35. As the plug is pressed against the cover plates, the prongs engage the contact strips 33 to complete the circuit, the beveled edges of the contact strips serving to spread the prongs slightly, whereby a good contact is assured. The plug is thus frictionally held by such engagement.
The foregoing description of the invention is explanatory thereof and various changes in the size, shape and materials, as well as in the details of the illustrated construction may be made, within the scope of the appended claims, without departing from the spirit of the invention.
