1. Field of the Invention
The present invention relates to electrical connector devices. More particularly, the invention relates to indoor electrical outlets and indoor electrical outlet covers.
2. Description of Relevant Art
Electrical service in buildings, particularly in homes, offices, and schools, is typically provided at least in part through electrical wall outlets. Devices needing electrical current for operation or use have electrical cords ending in electrical plugs for connection to an electrical wall outlet. Once the plug is inserted into the wall outlet, electrical current can flow (or does flow if the wall outlet has electrical current flowing into it) to the cord for activating the device needing current.
Most typically, when a plug with a cord is connected to an electrical wall outlet, the plug and cord extend several inches from the wall outlet before the cord curves to a parallel posture with respect to the wall. As a consequence, furniture or other items positioned adjacent to the wall, and even the item plugged into the wall outlet, must be positioned sufficiently away from the wall outlet to accommodate the plug and cord connection to the wall outlet and also to accommodate someone's hand and often times arm in reaching behind the furniture to insert the plug into the wall outlet. Such positioning wastes space in the room and is generally unattractive.
Moreover, typically and commonly used electrical wall outlets are themselves generally unattractive and are known to pose a potential safety hazard for infants and children. Blank cover plates and individual non-conductive plugs are commonly used to prevent children from inserting objects into wall outlet receptacles and getting shocked and injured thereby, but such plates and plugs then prevent use of the outlets.
At times it is desirable to dedicate an outlet to a specific appliance or electronic device but the outlet is not in the specific location desired for the specific appliance or electronic device, or the outlet needs to be covered to prevent access to infants and children, or the appliance or electronic device needs to be connected to the outlet and be flush against the wall adjacent to the outlet. Wiring the specific appliance or electronic device directly into the electrical wiring system in the building could perhaps meet these requirements, and certainly such wiring is known for lighting fixtures such as sconces and ceiling lights. However, installation of such direct wiring is time consuming and typically requires engaging an electrician and accessing the wiring behind the wall which often requires cutting a hole in the wall that later has to repaired. Further, such installation is more permanent than plugging an appliance or electronic device into a wall outlet and does not afford the luxury of easily moving or replacing the wired appliance or device. Thus there is a need in the art for meeting the needs presented above while overcoming the shortcomings presented above.
The present invention provides an indoor electrical wall outlet cover that solves the problems associated with indoor outlet covers and allows full access of electrical current from, and use of, the outlet for exclusive access by a particular small appliance, lamp, or electronic device, without requiring direct wiring of the small appliance, lamp, or electronic device to the building's internal electrical wiring structure. The present invention provides an indoor electrical wall outlet cover that is thin enough to avoid adding bulk to the outlet and thus enables the small appliance, lamp, or electronic device (or other items such as furniture) to effectively be positioned against the wall (or at least as close as the baseboard of the wall), that also covers the outlet so as to act as a safety device for a child that may seek to touch or access the outlet receptacles, and that still allows the small appliance or electronic device to be exclusively connected to the outlet and positioned a distance away from the outlet if desired. The present invention effectively provides a combination of advantages of plugging an appliance or electronic device into a wall outlet with advantages of electrically hard wiring the appliance, lamp, or electronic device directly into a wiring system, without the common disadvantages of each.
Moreover, the outlet cover is aesthetically pleasing--it is unobtrusive and calls less attention to itself than does the outlet without the cover of the invention. This is because the outlet cover, at least in one embodiment, is essentially or substantially blank, hides the receptacles of the outlet completely, and results in only one cord extending from the outlet and that extension is in a manner where the cord lies against the wall or along the wall or less than about an inch from the wall, at least when proximate the outlet.
The present invention effects these advantages by providing a thin cover, preferably smooth on the outside, that just extends fully over the surface of an electrical outlet having at least two receptacles, without protruding significantly therefrom and that has an electrical connection component on the backside, in the orientation of a three-prong plug used in
North America, that plugs into a receptacle of the outlet for making electrical contact and also for holding the cover in place. In one embodiment, the cover has an electrical connection component on the backside, in the orientation of an two-prong plug used in North America, that plugs into a receptacle of the outlet for making electrical contact and also for holding the cover in place. The difference between a two-prong plug and a three-prong plug is that a three-prong plug has a ground prong and corresponding ground wire, while a two-prong plug does not have a ground wire prong and corresponding ground wire. A three prong-plug is connected to a three core cable comprised of three individually insulated solid cores, typically copper, and individually insulated and wrapped in an outer polymerizing vinyl chloride (known as PVC) sleeving, while a two-prong plug is connected to a two core cable comprised of two individually insulated solid cores, typically copper, and individually insulated and wrapped in an outer PVC sleeving. A three core cable is typically used for appliances with a higher electrical current demand. The electrical connection component of the cover of the invention has an electrical cord attached thereto that extends downward from the electrical connection component out of the cover and falls generally flush against the wall and runs where desired to the small appliance, lamp, or electronic device to which the electrical cord is also connected and at which the electrical cord ends. The electrical connection component has electrical pins bent at approximately ninety degree angles so that the connection of that component in the receptacle does not add bulk or cause the cover to extend significantly beyond the outer surface of the electrical wall outlet.

The present invention provides for the indoor use of electricity through an indoor, thin, blank electrical wall outlet cover in a manner that fully conceals the underlying electrical wall outlet and an electrical plug directly connected to that outlet and an electrical connection component associated with that electrical plug and from which an electrical cord extends past, through, or out of the cover, in one embodiment at the base of the cover, and ending a desired distance away with its distal end directly connected by electrical wires to a small appliance, lamp, or electronic device.
This apparatus of the invention is particularly advantageous as a safety device that permits functional use of a standard or typical indoor electrical wall outlet while fully concealing the wall outlet and particularly concealing and shielding the openings or receptacles in the outlet from access by children. The apparatus of the invention obtains such safety advantage while being so thin as to avoid adding any significant bulk to the wall outlet, thereby enabling a user to position the appliance or device to which the apparatus is connected, or furniture or other items, in front of or adjacent to the outlet and essentially flush with, i.e., less than about an inch away from, the wall on which the outlet is located, or at least as close to the wall as any baseboard on the wall permits, and thereby providing another advantage of the invention.
The present invention eliminates the traditional manner of connecting a visible electrical plug to a visible indoor electrical wall outlet in order to consume electricity through such electrical wall outlet. The present invention also eliminates the traditional manner of accessing electricity for operating a lamp or appliance by hard wiring the lamp or appliance.
Interior electrical wall outlets are points in an interior space of a building such as a home where electrical current can be run to power electrical devices such as appliances and electronics. The most common such outlets are 15-amp (and sometimes 20-amp) duplex receptacles, which are designed to accept standard plugs for most small appliances, electronics such as televisions and home theater systems as well as cellular phones and portable computing devices such as laptops and tablet computers, and lamps. The invention has utility with any such interior electrical wall outlets and the term “typical (or standard) indoor electrical wall outlet” herein is understood to refer to such outlets as well as similar outlets that have more receptacles.
Referring to
As used herein, the term “frontplate” with respect to the apparatus of the invention and particularly cover 15 means the faceplate or faceplate component of cover 15, and not the common faceplate of the wall outlet. The apparatus of the invention is used to hide the wall outlet 11 but no change or adjustment in the wall outlet 11 needs to be made. That is, the common faceplate of the wall outlet 11 does not need to be removed. To avoid any confusion between the common faceplate of a wall outlet and the faceplate of the cover of the apparatus of the invention, the faceplate component of the cover 15 of the apparatus 10 of the invention will be called herein the “frontplate.”
The frontplate and backplate components of the invention are made of material that satisfies NEMA Standards or standards for UL safety certification. Such materials are characterized by resistance to chemicals, heat and impact, and typical applications include use in appliance housings and electronic and electrical assemblies. These materials include various plastics, including acrylonitrile butadiene styrene or ABS and polyvinyl chloride or PVC.
The maximum distance between the backplate component 14 (or 14a or 14b) and the frontplate component 12 is approximately the height or thickness of the electrical cord 13 (or 16) connected to or attached to the backplate component 14, and this distance is only in the main body or central portion of the cover 15, as the outer or perimeter edges of the components 12 and 14 are proximate one another and touch or essentially touch, with the perimeter edge of backplate component 14 or 14a or 14b fitting inside the outer edge of frontplate component 12, as shown in
An integral aspect of this embodiment of the apparatus 10 of the invention is the electrical pins 18 and 28 and ground wire 19, which are bent at approximately a ninety degree angle with respect to the backplate component 14 (14a and 14b would be the same) and fastened to the backplate component 14 (14a would be the same), as shown in
A benefit of the electrical pins 18 and 28 and the ground wire 19 being bent at a ninety degree angle is that the depth of the cover 15, measured by the distance between the wall 23 when the cover 15 is inserted in the underlying electrical wall outlet 11 and the front face of the cover or the outer or exterior surface of the frontplate component 12, resting on top of the backplate 14 (or 14a or 14b) which in turn is resting on top of the underlying electrical wall outlet 11, is less than the depth of a typical electrical plug connected in a traditional manner to the electrical wall outlet 11, which is a typical electrical wall outlet, and cover 15 may have less depth than the depth of baseboard molding 21 at the base of the wall 23. For example, a typical electrical plug is at least about an inch wide and when on an electrical cord and inserted into an electrical wall outlet, such as electrical wall outlet 11, such plug and adjacent cord typically protrude or extend outwardly from the outlet a distance of more than an inch and often protrude as much as about two inches to even four inches. In contrast, the cover 15 of the apparatus 10 (or 10a or 10b) of the invention when placed over the electrical wall outlet 11 extends outward from the outlet no more than the thickness of the cover 15. Cover 15 is as thin as the thickness of the combination of the frontplate component 12 mounted on the backplate component 14 and the electrical pins 18 and 28, the ground wire 19, and electrical cord 13 in between the components 12 and 14. This combined thickness, or thinness, is less than about an inch and also is less than the thickness of a typical baseboard at the base of a wall in preferred embodiments.
As shown in
The conductive electrical pins 18 and 28 and ground wire 19 and corresponding plug prongs 20, 30 and 22 comprise a configuration of one of about fifteen electrical plug types currently in use, as categorized by the U.S. Department of Commerce International Trade Administration. An integral aspect of this embodiment is connection of the electrical pins 18 and 28, through respective plug prongs 20 and 30, to the respective contacts 31 and 33 in a receptacle 45 of wall outlet 11 as shown in
The opposite or distal end of the electrical cord 13 (or 16) is directly connected through electrical wires to a small appliance, lamp or electronic device 35 for utility, namely electricity consumption. Such third-party small appliances, lamps and electronic devices (and the like) are not part of the invention. The exact desired length of electrical cord 13 (or 16) will vary depending on the intended use of the invention, that is, depending on the particular small appliance, lamp or electronic device that will be attached to the electrical cord 13 (or 16) and depending on the expected desired positioning of that appliance, lamp, or electronic device. In one embodiment for example, such as for a lamp or a television for non-limiting example, the length is sufficient for electrical cord 13 (or 16) to extend from backplate 14 (or 14a or 14b) or cover 15 and be manually guided around any adjacent or nearby furniture and positioned so that the distal end of the electrical cord 13 (or 16) of apparatus 10 (or 10a or 10b) of the invention and its attached lamp or television are conveniently and safely located for use. In one embodiment, for example, the distance the cord will extend is selected from a range of about three feet to about thirty feet, although many different variations would work, and longer cords could be used. The length of the cord is generally limited by practical reasons—one does not want a cord so long that excess cord gets in the way of furniture and becomes unsightly or a tripping hazard. In another embodiment, the length of electrical cord 13 (or 16) may be short—only so long as to reasonably enable the cover 15 to be plugged into the wall outlet 11 with the attached small appliance, lamp, or electronic device positioned in front of or adjacent the wall outlet 11. As stated above, the present invention can advantageously enable furniture, or the appliance or device to which the apparatus of the invention is connected, to be positioned flush against the wall and in front of a wall outlet covered by the cover 15 of the apparatus of the invention.
As indicated above, through use of electrical cord 13 (or 16), the apparatus of the present invention advantageously eliminates the need to attach an electrical plug of a small apparatus, lamp, or electronic device directly to the contact openings or receptacles of an electrical wall outlet for use of the outlet.
The apparatus of the invention also advantageously can be used with any standard, conventional, or typical indoor electrical wall outlet, without having to make any adjustments or physical changes in the wall outlet. Screws are not needed for attachment of the cover of the apparatus of the invention to the wall outlet for covering the wall outlet and the wall outlet does not need to be replaced with a frontplate particularly designed to fit with the cover of the apparatus of the invention. Rather, the apparatus of the invention and particularly the cover 15 of the apparatus of the invention 10 is held in place over the wall outlet 11 by insertion of prongs 20, 30, and 22, in receptacle 45 of the wall outlet 11, as indicated in
Wall outlet 11, as indicated in
The apparatus of the present invention can also be readily adapted for standard, conventional, or typical multi-gang outlets, such as for nonlimiting example, double or triple wall outlets. Such outlets tend to simply be double, triple, quadruple, or other multiple versions of a single gang outlet and thus respectively have four, six, eight, or other multiple receptacles or sockets typically aligned in pairs. Thus the apparatus of the invention would be expanded to accommodate four, six, eight, or other multiple pairs of electrical plugs. For another example, in one such alternative embodiment, the multi-gang electrical outlet is sized to support up to about sixteen receptacles or sockets, normally allowing attachment or insertion into the multi-gang electrical outlet as many as sixteen electrical plugs, or an apparatus of the invention with eight electrical plugs.
In such alternative embodiments of the invention not shown for use in multi-gang outlets, the backplate component of the cover of the apparatus of the invention is sized to align and position over such standard indoor multi-gang electrical wall outlet. The frontplate component is sized to align and position over and curve slightly around the perimeter edge of the backplate component for a tight fit as described above that preferably requires no adhesive or screws to stay in place. To add to the aesthetics of the cover 15 of the invention, in one embodiment at least the front or exterior of the frontplate is painted or is covered in wallpaper.
In another embodiment of the apparatus of the invention, having an alternative electrical connection to that discussed above and illustrated in
The present invention has been illustrated with electrical plugs and receptacles having shapes that are commonly used in the United States of America. However, it is known that different shaped electrical plug prongs and receptacles are used in different countries and the present invention may readily be adapted for those different shapes.
While preferred embodiments of the present disclosure have been described, it should be understood that other various changes, adaptations and modifications can be made therein without departing from the spirit of the invention(s) and the scope of the appended claims. The scope of the present disclosure should, therefore, be determined not with reference to the above description, but instead should be determined with reference to the appended claims along with their full scope of equivalents. Furthermore, it should be understood that the appended claims do not necessarily comprise the broadest scope of the invention(s) which the applicant is entitled to claim, or the only manner(s) in which the invention(s) may be claimed, or that all recited features are necessary.
