' extent.

Considering the figures in which like numerals have reference to the same parts, in Fig. 1 the numeral 11 repre sents a substantially rigid non-conducting outer channel member having an inner surface 12, and an outer surface 13 meeting a bottom surface 14 along corner 15. Corner 15 is adapted to seat along a wall at its juncture with the top of a baseboard. The outer channel member 11 includes a pair of

outer lips

16 and 17, a wedge-shaped aligning slot 18 running the length of the outer channel member, and a plurality of spaced holes one of which is shown at 19.

Inner channel member 20 is also rigid and includes a back surface 21 adapted to contact inner surface 12 of the outer channel member 11. To ensure proper contact a wedge-shaped protrusion 22 is provided, running the length of the inner channel member and conforming in contour with aligning slot 18. The inner channel member includes a slot 23 and a plurality of holes corresponding with those of the outer channel member, one of said holes being shown at 24.

Inner lips

25 and 26 extend from the back surface and include

sections

27 and 28 about which they may be resiliently displaced to a small These

sections

27 and 28 are necked-down, i. e., of reduced transverse thickness relative to the abutting portion of the lip, so that the indicated resilient displacement can occur in spite of the substantially rigid character of the channel member.

Conductors

29 and 30 are resilient and generally C-shaped in cross section, fitting into the passages between the inner and outer channel members. Screw 31 passes through

holes

24 and 19 and then into the wall, thereby affixing the inner and outer channel members to each other and to the wall. Spreading element 32 fits into slot 23 of the inner channel member and by spreading apart necked-down

sections

27 and 28 ensures a positive, pressure contact between

inner lips

25 and 26 and

outer lips

16 and 17, respectively.

In the preferred embodiment of Fig. 2, substantially rigid, nonconducting channel member 41 includes rear surface 42 and bottom surface 43 meeting along corner 44. Rigid

outer lips

45 and 46 contact or lie close to rigid

inner lips

47 and 48, respectively, enclosing

therebetween channels

49 and 50, respectively.

Inner lips

47 and 48 extend from rear surface 42 and include necked-down

sections

51 and 52, respectively. Between these necked-down sections, a slot 53 is positioned for receiving a spreading element which effects a positive;

pressure contact between the pair of lips by forcing the inner lips apart.

Conductors

54 and 55 are embedded in the outer lips and extend into the

channels

49 and 50, respectively, running the length of the channel member.

'Fig. 3 shows a simplified form of the outlet of Fig.

1. The outer channel member 61 is similar to outer.

of screw 71 passing through the innerchannel membery through the outer channel member, and into the wall, simultaneously serves to establish a positive pressure con-- tact between the pairs of lips by pivoting the inner lips towards each other slightly about the necked-down sec tions.

Figs. 4 and 5 show modified outlets with conventional outer channel member ll and conductors 29 and30 described in reference to Fig. 1, and inner channel member 66 described in reference to Fig. 3. The

prongs

72 and 73 of plug 74 extend between pairs of

lips

16, 67 and 17, 68, respectively, and

contact conductors

29 and 30, respectively. The resiliency of the conductors produces some retaining action on the prongs while the pivotal displacement of the inner lips about their neckeddown sections effects a strong gripping action on the prongs.

In Fig. 5 the positive pressure contact between the pairs of lips effected by spreading element 32 is transferred to a strong gripping action on the

prongs

72 and 73. The prongs contact embedded

conductors

54 and 55 and because of the shape of the conductors the prongs are displaced slightly towards each other, which displacement serves to 'grip the prongs more securely while simultaneously assuring electric contact.

Where the outlet comprises a separate inner and outer channel member these members may be secured to each otherby means other than that which secures the assembled outlet to the wall. For example, separate screws may be provided so that as purchased the only operation necessary to complete installation will be fastening of the previously assembled outlet to the wall.

Because of the external appearance the continuous outlet may constitute a molding along the juncture of the wall and floor of a room or may constitute an elevated molding along a wall since it need only be secured to the wall. Alternatively, it may be employed as a part of a molding in conjunction with other elements conventionally employed. In either event, the device is attractive and its presence is neither obtrusive nor de- 'structive of the beauty of a room, permitting electric appliances to be inserted anywhere along its length. Furthermore, the device can readily be removed by reversing the installation steps and only an occasional screw hole will evidence its former position.

The embodiment shown in Fig. 2 is particularly economical to manufacture and assemble since the entire outlet save the spreading element is a single piece. In place of a continuous spreading element, a plurality of short spreading elements may be utilized and inserted in the slot between the inner lips at spaced intervals. As shown in Fig. 1, the slot 23 may be a taper continuous with the exterior surfaces of the inner lips. Alternatively, as shown in Figs. 2 and 5, the slot 53 may be discontinuous with the exterior surfaces of the inner lips, providing a notch which serves to prevent dislodging of the spreading element. The shape of the spreading element may be varied so long as it serves to displace the inner lips from each'other.

The conductors have been shown as embedded in the outer lips. The shape of the conductors may be varied considerably but for embedded conductors, fiat contact surfaces having their rear edges positioned more closely to each other than their leading edges is preferred since electrical contact is ensured. V

' As has been noted, although the channel members are substantially rigid, the necked-down sections on the inner'lips effect the closure of the conductor channels as well as effecting the requisite grip on the prongs of the plugs by permittingslight pivotal movement of the inner lips. While the outer lips could be necked-down where the outlet is attached to a wall elsewhere than along the 1 floor so that the outer lips may be deflected, this form is not as desirable as whereit' is the inner lips which are so proportioned, The preferred form prevents spread ing of the outer lips and furtherplaces absolute limits on the amount of displacement to which the inner lips may be subjected, i. e., from contact with each other to contact with theouter lips. Since theouter lips if neckedldow'n would be limited in movement only in the direction towards the inner lips, movement away from the inner 'lips could be carried tothebreaking point.

The tight seal between-the pairs of lips prevents the plug from being accidentally dislodged and at the same time prevents the entry of dirt or moisture into the conductor channels. The conductors are well insulated from each other and because of the rigidity of the lips there is insufficient space for a child to insert even his smallest finger. Any arcing which might occur during insertion or removal of the prongs is confined to the conductor channel and is isolated from the other channel or any inflammable materials.

The channel member or members is preferably composed of a plastic material which is insulating, non-conductive, and resistant to deterioration due to heat, cold, moisture, or conventional household cleaning agents. The use of a synthetic materialpermits the member or members to be extruded continuously and the extruded product has a high gloss and attractive appearance. In addition, fillers or pigments may be incorporated in the plastic mass to produce a variety of colors.

The finished article because of its moisture resistance and lack of openings may be cleaned safely and easily merely by wiping with a damp cloth, requiring no special precautions. The extrusion of continuous lengths of material permits a single piece to be used for each wall preventing unattractive joints which serve to collect dust.

Furthermore, the outlet can be painted simultaneously with its support without fear of damage by the paint or the solvents.

Where the outlet is to be introduced into a new home the conductors may be connected to the power supply through the back. In existing homes the outlet can be worked into the power supply in similar manner or may be energized by employing a wire having a plug at each end, one plug inserted into an existing socket and the second end into the new outlet. Suitable links for lengths of the outlet and for turning corners may be provided, but do not constitute the subject matter of the present invention. Furthermore, special caps may be provided for the ends of the outlet where it is not continuous but these similarly do not form the subject matter of this invention.

Because of its construction, it is apparent that the novel outlet is rugged and safe.

The conductors which are metallic and preferably of copper may likewise be extruded continuously and they may be flexible or rigid. Preferably, however,they are rigid and may be embedded in the channel members by continuous extrusion therewith. Consequently, the preferred embodiment of Fig. 2 may be produced almost in its entirety by a single procedural step. This ease of manufacture is accompanied by extreme ease of assembly and represents a practicality which permits the novel outlet to be fabricated at a minimum expense.

Accordingly, there has been described a continuous electric outlet comprising, in combination, a plurality of spaced longitudinally extending substantially rigid members, each of said members being provided with abutting lips defining an insulating channel there-between, said lips being composed of an insulating material, at least one lip of each of said members being provided with a neckeddown section extending longitudinally of said insulating channel, and a plurality of longitudinally extending conductors disposed within said insulating channels, respectively,'whereby upon insertion of the prongs of an electric plug between said lips of said members, respectively, into said insulating channels, respective lips are displaced about said necked-down sections and said prongs are strongly gripped by saidlips.
