Abstract

Electrical wiring forming the cords of domestic appliances such as clocks and lamps is unsightly and generally hangs or runs loosely from the appliances to the electrical outlets in a room. In order to hide such wiring and maintain it in an orderly condition, an electric cord holder and cover has been devised. The electric cord holder and cover (10) includes an elongated plastic extrusion of tubular shape which is a cross-section in the form of a substantially C-shaped front portion (11) and an overhang, and a rear portion (12) extending inwardly from one end of the C-shaped portion (11) towards the other end of the C-shaped portion, yet leaving a slot (17) adapted for insertion of electrical wiring between the inwardly extending rear portion (12) and the other end of said C-shaped portion (11), and a securing strip (14) of predetermined width which defines an outer surface. The securing strip (14) is connected to the rear portion (12) and is adapted to be attached to an external surface. The overhang extends outwardly up to the outer surface, so as to be flush therewith. The electric cord holder and cover (10) may then be attached to an external surface with the overhang abutting the external surface.

Description

ELECTRIC CORD HOLDER AND COVER Field of the Invention.
This invention relates to an electric cord holder for hiding electrical wiring.
Background of the Invention.
From French patent 1,161,556 there is known an electric cord holder which, as seen in cross-section, is substantially O-shaped, or B-shaped, and includes flanges extending outwardly along a corresponding longitudinal portion of the O-shaped or B-shapsd cross-section. An adhesive strip is mounted on the flanges, and is provided with a protective covering which is stripped off prior to the intended use of the cord holder. In order to form the electric cord holder, according to the French patent, the cord holder is preferably created by surrounding a pair of electric wires initially with a protective sheet, as no provision exists to slide a pair of wires into the cord holder along a longitudinal slit. Also the outwardly extending flanges require an excessive amount of space, which is disadvantageous in some applications.
From British patent 966,921, issued to Andersson, there is known a casing in the form of a clam-shell molding, for
OMPI example, £or electrical cables, which, as seen in cross-section, is substantially J-shaped, or has a substantially J-shaped contour; it includes in some version a portion extending at right angles from the topmost cross-leg of the J-shaped cross-section on an inner side thereof towards the arcuate portion of the J-shaped cross-section. This relatively large-dimensioned configuration is suitable for installation , for example, along a floor, where the floor meets an upstanding wall, as sharp edges are avoided thereby. But it has disadvantages when used free-standing, because it inconveniently exposes its sharp edges, thereby possibly causing injuries when a person inadvertently brushes against those sharp edges.
Summary of the invention.
It is accordingly an object of the present invention to obviate the disadvantages of the prior art. This object is attained by providing an electric cord holder which has a cross-section in the form of a substantially C-shaped front portion which has an overhang, and a rear portion extending 'inwardly from one end of the C-shaped portion towards the other end of the C-shaped portion, yet leaving a slot adapted for insertion of electrical wiring between the inwardly extending portion and the other end of the C-shape portion. Securing means of predetermined width, which defin an outer surface, are connected to the rear portion, and ar adapted to be attached to an external surface so as to support the electric cord holder on the external surface; the overhang extends outwardly up to the outer surface so as to be flush therewith, so that the electric cord holder may be attached to the external surface with the overhang abutting the external surface.

Description of the preferred Embodiments.
Referring now to the drawings, and in particular to FIGS.1-3, an electric cord holder 10 includes an elongated sheath made from an extruded plastic material, so as to be inexpensive to manufacture, and so that it can be formed in any of various attractive shapes to harmonize with the room decor. The plastic material is preferably semi-soft, so that it may be easily cut to any desired length by a knife or a hack saw.
Generally this sheath includes a front wall 11 visible for viewing, which is generally C-shaped in cross-section, arid which encloses the electric wiring, so that it is not visible from either the front, or the sides of the eleccric cord holder. The C-shaped cross-section of the electric cord holder, according to the present invention, may be arcuate, subtending an angle from about 180° to about 270°, as shown, for example, in FIG.7, or may have in part a substantially semi-circular cross-section, as shown, for example, in FIG.4, or may have a substantially rectangular cross-section with rounded corners, as shown, for example, on FIG.5. It may, alternatively be otherwise shaped, for
1
Figure imgf000007_0001
example being fluted, so as to suitably blend in with the room decor and resemble a decorative molding.
The sheath also includes a flat rear portion or rear wall 12, for being attached to an external surface, such as a wall 13 of a room. A rear side of the rear portion or rear wall 12 is coated or provided with pressure sensitive securing means, such as an adhesive strip 14, as shown, for attachment to the wall 13, after a protective cover 15 is first peeled off from the adhesive strip 14. Alternately loop pile fastener means may be used, particularly when mounted on a fabric-covered wall, so that the loop pile provided on the rear of the electric cord holder 10 adheres thereto.
A longitudinal strengthening gusset 16 -is preferably provided in one corner, namely near one end of the cross-sectionally C-shaped front or front portion 11, and the rear wall or rear portion 12 of the electric cord holder 10, and is integral with these portions.
An elongated slot 17 is formed between the rear wall 12 and one end of the cross-sectionally C-shaped front wall 11, in order to allow insertion of the electrical wiring 18 therethrough, and into a channel 19 of the electric cord holder 10. The slot 17 can be formed either along one side edge of the rear wall 12, or else along the center thereof. It is, however, preferable to employ a configuration where the slot 17 is formed along one side edge of the rear wall 12, as it is then possible to lift the other, generally
Figure imgf000008_0001
resilient side edge, to slide any particularly bulky wirin through the slot 17. In either case a single protective cover or release strip 15, such as paper, could be used fo protecting the adhesive strip 14.
In operative use, once the wiring 18 is tucked through the slot 17 into the electric holder 10, the rear wall 12 acts to hold the wiring 18 in place, so that the electric holder 10 can be more easily attached to a baseboard, wall, ceiling or the like. In the illustrative example, the electric cord holder 10 encloses the wiring 18 between a wall-mounted electric clock 20 and a house electric socket 21.
As particularly seen in FIGS.4, 5, 7 and 8, an overhang 22 extends from one end of the front wall or front portion 11 rearwardly up to an outer surface of the adhesive strip 14, so as to be flush therewith. Thus the electric cord holder 10 may be attached to the external surface or wall 1 with the overhang 22 abutting the wall 13. Consequently, 'the cord holder 10 can be attached to a wall or the like without leaving any spaces between itself and the wall.
In a preferred form of the invention, another portion 2 or 23',. as seen in cross-section of the electric cord holde 10, and as best seen in FIGS.4 and 5, extends interiorlv towards the front wall 11 so as to leave the slot 17 betwee the overhang 22 and the portion 23, but forming with the rear wall 14 a trough 24 or 24', in which the electric , wiring 18 can be nestled. Alternately, or additionally, two radially inwardly extending ribs 25 or 25* can be provided on the interior of the front wall 11 or 11', so that the electric wiring 18 can be alternately nestled between the ribs 25 or on one side of the ribs 25, on one hand, and the aforedescribed trough 24, on the other hand.
It is especially advantageous if the cross-sectionally C-shaped front wall 11 is provided with an inwardly projecting longitudinal bulge 26 facing the rear wall or rear portion 14, as best seen in FIG.8, and if the leg of the front wall 11, on which the bulge 26 is formed, is made of resilient material. In this manner the wiring 18 can be inserted through the slot 17 into the electric cord holder 10, thereby forcing the bulge 26 outwardly; as soon as the wiring 18 is, however, contained in the electric cord holder 10, the bulge 26 snaps back, thus securely enclosing and protecting the electric wiring 18.
In order to permit two electric cord"holders 10 to be jointed at right angles, it is advantageous to form an end 'part of the electric holder so that it slopes at an angle of about 45° with respect to its longitudinal axis. This is best seen in Fig. 9 , which shows three electric cord holders 10 to be joined to one another so as to form a U-shaped configuration. But the ends of the cord holders can also be shaped, so that one cord holder can extend, for example, along an upright wall, and the other cord holder to be joined thereto at right angles can extend, for example, along the ceiling. ' ^__----»_^ If the electric wiring 18 is inserted in snaked form into the electric cord holder 10, as shown, for example, in FIG.6, sufficient rigidity is provided so as to enable the electric wiring 18 to abut the interior surfaces of the cord holder 10. This advantageous configuration permits the cord holder 10, for example, to be free standing without the risk of the electric wiring 18 sliding within the cord holder 10. It will be understood, however, that the wiring 18 may also be arranged to slide within the electric cord holder 10, if it is of a width or diameter smaller than the internal bore of the electric cord holder 10, and this may be advantageous in some applications, whore the wiring has to be adjusted prior to final installation. It will be also understood that the wiring 18 may alternately be inserted into the electric cord holder 10 from one end thereof; this form of insertion may be useful and desirable, where the cord holder 10 is already attached to a wall, and it is not desired to remove the cord holder 10 from the wall, before inserting the electric wiring 10 through the slot 17.
In a preferred version of the invention, the width of the slot is about 1/4". It will be appreciated that the electric cord holder, according to the present invention, can be affixed not only to a wall, but to a ceiling or to' a baseboard. It can be arranged to be self-supporting, or where it is required to be attached to a wall or the like, such attachment can be performed manually without the use of any tools of any kind. It can generally be form-fitted to the surroundings, and will be found to be quite unobtrusive. It should also be pointed out that the inwardly curved end 22' 'of the C-shaped front wall 11", shown in FIG.7, as well as the inwardly curved bulge 26 shown in FIG.8, serve to retain the snaked-in wire 18, shown in FIG.6. When the wire is inserted into the electrical cord holder 10 in a snaked-in fashion, either the bulge or the inwardly curved end act to hold the wire in the holder.
From an esthetic point of view, since the electric cord holder 10 may be made of various colors and finishes, to the user's eye, it becomes part of the decor of the room, or of the lamp or clock to which it is connected, and the fact that it is indeed used to hide electric wiring, is forgotten.
While only a few embodiments of the present invention „have been shown and described, it is obvious that many changes and modifications may be made thereunto. In particular, specific features of one version of the invention can be combined with specific other features of another embodiment of the invention without departing from the spirit and scope of the invention.
