Abstract:
A telescoping in-use cover plate that includes at least two inter-fitting members that enable the cover to be retracted to the wall when not in use and expanded to increase the depth of the outlet cover and allow a plug to be plugged into the outlet when the cover is closed. Specific implementations allow for vertical and horizontal mounting and installation, knockouts and/or adapter plates for conversion to alternate electrical configurations.

Description:
RELATED APPLICATIONS 
   This document is a continuation of U.S. patent application Ser. No. 11/422,583 which was filed on Jun. 6, 2006, the disclosure of which is hereby incorporated herein by reference. 

   BACKGROUND 
   1. Technical Field 
   Aspects of this document relate generally to expandable small electrical device covers, such as for use with electrical outlets and switches. More specific implementations involve covers that can be flattened while not in use and expanded to a depth sufficient to house a plug while the outlet is in use. 
   2. Background Art 
   In-use outlet covers are those outlet covers that are configured to allow an electrical plug to be plugged into the outlet while a protective cover is closed. Having the cover closed while being used allows the cover to protect the outlet from the elements, such as rain, moisture and dust. 
   Conventionally, to enable an electrical outlet cover to close while the outlet is in use, the base or lid of the cover unit needs to be adapted to be deep enough to allow for the lid to close without significant interference with the plug when the plug is inserted into the outlet. Some of the conventional approaches to accomplishing this deeper base are shown and described in U.S. Pat. No. 6,723,922 to Shotey et al. (Issued Apr. 20, 2004) titled “Universal cover plate”, U.S. Pat. No. 6,133,531 to Hayduke (Issued Oct. 17, 2000) titled “Weatherproof outlet cover”, U.S. Pat. No. 4,988,832 to Shotey et al. (Issued Jan. 29, 1991) titled “Recessed electrical outlet with cover”, U.S. Pat. No. 4,803,307 to Shotey et al. (Issued Feb. 7, 1989) titled “Weatherproof outlet cover”, the disclosures of each of which are hereby incorporated herein by reference for their general relevance to the formation and manufacture of cover assemblies. 
   Each of these designs involves a cover unit having a fixed dimension using what is typically called a bubble cover lid that bulges to allow room for the plug and cord within the cover when it is closed. One of the common complaints associated with conventional in-use cover designs is that the cover units protrude three or more inches from the exterior of the home, may be damaged or dislodged by passers-by, and are often unattractive on the home due to the size. 
   Horizontal and vertical mountable electrical device cover assemblies using hinges are known in the art. Some examples of these assemblies are shown and described in U.S. Pat. Nos. 5,763,831 to Shotey et al. (issued Jun. 9, 1998) titled “Universal Cover Plate, Cover Plate Assembly, and Related Methods,” 6,133,531 to Hayduke et al. (issued Oct. 17, 2000) titled “Weatherproof Outlet Cover,” 6,441,307 to Shotey et al. (issued Aug. 27, 2002) titled “Universal Cover Plate,” 6,476,321 to Shotey et al. (issued Nov. 5, 2002) titled “Horizontal and Vertical Mountable Weatherproof Cover Plate,” 6,979,777 to Marcou et al. (issued Dec. 27, 2005) titled “Weatherproof Electrical Enclosure Having an Adjustable-Position Cover,” 6,894,223 to Shotey et al. (issued May 17, 2005) titled “Horizontal and vertical mountable weatherproof cover plate”, and U.S. patent application Ser. No. 11/056,835 to Shotey et al. (filed Feb. 11, 2005) titled “Weatherproof Receptacle Cover with Adapter Plate,” the disclosures of each of which are hereby incorporated herein by reference for their general relevance to the formation and manufacture of cover assemblies. Such assemblies are conventionally made of plastic or metal, may be converted for use with removable portions to adapt the electrical device openings of the base for use with many different types of electrical devices using the same components, and may incorporate spring biased hinge members to enable use in both horizontal and vertical orientations using the same assemblies. 
   Typical base configurations for electrical devices include, but are not limited to, blank, duplex, decora, ground fault circuit interrupt (GFCI), round and switch. Examples of structures that may be used to enable a base member to be configured for conversion between various other configurations are shown and described in U.S. Pat. Nos. 6,723,922 to Shotey et al. (issued Apr. 20, 2004) titled “Universal cover plate”, 6,987,225 to Shotey et al. (issued Jan. 17, 2006) titled “Convertible electrical device cover and method for installing same”, 6,441,307 to Shotey et al. (issued Aug. 27, 2002) titled “Universal Cover Plate,” and 6,770,816 to Shotey et al. (issued Aug. 3, 2004) titled “Convertible electrical device cover and method for installing same”, the relevant disclosures of which are hereby incorporated herein by reference. Alternatively, as suggested in U.S. Pat. No. 6,770,816, the base member may be configured with an opening and attachment members and replaceable adapter plates may be used to enable the installer to select the desired base configuration. These references also include examples of removable cord escape tabs for vertical or horizontal orientations. 
   The base member may also be configured to cover the socket face of the outlet to which it is attached but allow for plugs to extend through the cover to the electrical outlet. Examples of outlet covers that are configured to cover the socket base are shown and described in U.S. Pat. No. 6,761,582 to Shotey et al. (issued Jul. 13, 2004) titled “Receptacle-mounted cover plate to hide electrical socket face”, the disclosure of which is hereby incorporated herein by reference. 
   SUMMARY 
   Instead of having a rigid cover depth like conventional in-use outlet covers, implementations of an electrical device cover assembly each include an adjustable depth cover. Adjustability is made possible, in particular implementations, through the use of two or more telescoping sections that extend to one or more in-use positions when it is desired to use the outlet while the cover is closed, and retract to a storage position when there is no need to have the cover closed with a plug inserted. 
   In one aspect, this document features a telescoping cover assembly for an electrical device that retracts to a relatively shallow depth when not in use and expands to a depth such that the cover may be closed while the device is in use. For example, when the electrical device is an outlet, the cover extends to a depth such that a plug may be plugged into the outlet and the cover may be closed over the plug and the outlet. Various implementations include implementations having an expandable base, implementations having an expandable cover, implementations having indentations on non-adjacent sides of the cover to facilitate grasping the cover, implementations having angled sidewalls, curled interlocking portions and stopper portions that maintain the expanded or collapsed position, implementations having living hinges connecting the telescoping members, implementations for a rectangular base and cover, and implementations for a round base and cover. The base and cover may be formed from plastic, resin, rubber, metal or other conventional material for forming electrical device covers using conventional fabrication methods. 
   Specifically, each of the electrical device cover assemblies may include a cover and a base. It should be clear from the disclosure herein that although the specific implementations show the base configured for use with a duplex electrical outlet, it may alternatively be configured, directly or through the use of removable tabs or adapter plates, for use with a different electrical device such as, and without limitation, an electrical switch, a GFCI outlet, a round outlet, an electrical cable, multiple electrical devices, and the like. Examples of such convertible adapter plates and bases were previously incorporated by reference. Covers and bases configured according to the implementations disclosed may be formed of metal or non-metal, such as plastic, rubber or resin depending upon the use for the particular cover assembly. 
   For particular implementations, a cover may include one or more inter-fitting, telescoping base members. The cover may be attached to a base by hinges or other appropriate attaching devices. There may be indented portions on non-adjacent sides of the cover. One or more sidewalls of the inter-fitting telescoping members may include a slanted sidewall, a curled inner portion, a curled outer portion and a stopper portion. The curled inner portion of a larger telescoping member may interlock with the curled outer portion of a smaller telescoping member when the outlet cover is in the expanded position. When the outlet cover is in the retracted position, the curled outer portion of the smaller telescoping member rests against the stopper portion of the larger telescoping member. The outlet cover may include hinges on adjacent sides of both the base and the cover so that the outlet cover can be adapted for either horizontal or vertical use. 
   For other particular implementations, the telescoping members are connected by a living hinge. A clip may be included to hold the telescoping members in the retracted position. 
   For other particular implementations, the telescoping members may be round. The round telescoping members may be expanded by twisting in a screw-type motion or by pulling in an accordion-type motion. 
   The foregoing and other aspects, features, and advantages will be apparent to those artisans of ordinary skill in the art from the DESCRIPTION and DRAWINGS, and from the CLAIMS.

   DESCRIPTION 
   This disclosure, its aspects and implementations, are not limited to the specific components or assembly procedures disclosed herein. Many additional components and assembly procedures known in the art consistent with the intended cover assembly and/or assembly procedures for a cover assembly will become apparent for use with implementations of extendable device cover assemblies from this disclosure. Accordingly, for example, although particular hardware is disclosed, such hardware and implementing components may comprise any shape, size, style, type, model, version, measurement, concentration, material, quantity, and/or the like as is known in the art for such hardware and implementing components, consistent with the intended operation of an extendable electrical device cover assembly. 
   A break-apart view of one implementation of the electrical device cover  2  is shown in  FIG. 1 . The electrical device cover assembly  2  includes a base  4  and a cover  6 . The cover  6  of this particular implementation includes a plurality of telescoping members. Specifically, the cover  6  may include a base telescoping ring  8 , a plurality of middle telescoping rings  10 ,  12  and  14  and a cover telescoping member  16 . Each telescoping member has a smaller diameter than the previous telescoping member and the smaller telescoping members  16 ,  14 ,  12  and  10  fit within the bigger telescoping members  14 ,  12 ,  10  and  8 , respectively. Thus, the telescoping members  8 ,  10 ,  12 ,  14  and  16  may nest within each other in the collapsed position (see  FIG. 3 ) and the depth of the collapsed cover  6  is about the same as the depth, D, of the base telescoping ring  8 . 
   The depth of the expanded cover, D E , is at least about two times the depth D of the base telescoping ring  8 . The telescoping members  8 ,  10 ,  12 ,  14  and  16  can be configured to have any desired depth and the cover  6  can include any desired number of telescoping members. Therefore, the expanded depth D E  can be about 2 to 5 times deeper than the collapsed depth D. 
   The base  4  includes mounting screw openings  56  and electrical device openings  52 . As explained above, and examples of which were incorporated by reference, the electrical device openings may be configured in many different configurations including, but not limited to, differently shaped openings, openings with removable tabs for adapting the openings to a variety of electrical device shapes and sizes, and/or adapter plates. 
   The assembly  2  may also include a cord escape  58 , as shown in  FIG. 1 . Alternatively, the assembly may include removable or “knock-out” tabs in the vertical and/or horizontal orientation that, when removed, provide cord openings. Examples of such cord openings and removable tabs were previously incorporated by reference. 
   The assembled electrical device cover  2  can be expanded, as shown in  FIG. 2 , by grasping the indented portions  20  on opposing sides of the cover telescoping member  16  and pulling. The indented portions  20  on the cover telescoping member  16  allow for easy gripping of the extendable cover  6 . The indented portions  20  may each include a protruding lip  22 , as best shown in  FIG. 1 . Although the indented portions  20  are shown located on the longer sides of the cover telescoping member  16 , the indented portions could alternatively be located on the shorter sides of the cover telescoping member  16 . In still other implementations, the indented portions  20  could be eliminated or the cover telescoping member  16  could include only one indented portion or indented portions on adjacent sides. In still yet other implementations, the indented portions could be located on the front surface of the cover member  16  rather than on an edge. Although the indented portions  20  are shown having a curved shape, other shapes, such as rectangular, would also achieve the intended purpose. Other alternative or additional gripping members for facilitating grasping and pulling could be included on the electrical device cover  2 . 
   In the example shown in  FIGS. 2 and 3 , the cover  6  is attached to the base  4  with hinges  30  disposed on the longer side of the base  4  and the cover  6 . The National Electric Code requires that for in-use electrical outlet covers, the lid should close against the base on its own. Generally, this is accomplished through the use of gravity, with the hinge axis of rotation being substantially parallel to, or at least more horizontal to than vertical to, the ground when installed. Thus, the example shown in  FIGS. 2-3  would be for a horizontal orientation. That is, the hinges  30  would be parallel to the ground. With the hinge axis of rotation parallel to the ground, the lid closes on its own under the force of gravity. Thus, it may be desirable for hinge members to be included on more than one side of the base  4  and cover  6 , or even on a corner of the base  4  and cover  6  to enable the cover unit to be mounted and installed either horizontally or vertically using the same cover unit. Examples of such electrical device covers with alternative hinge assemblies were previously incorporated by reference. Such examples of alternative hinge assemblies may be readily incorporated into the present implementations by those of ordinary skill in the art without undue experimentation. In other particular implementations, the hinge assemblies may be replaced by one or more living hinges comprising a flexible material joining the cover  4  and one or more sides of the base  4  or a telescoping ring. 
     FIG. 4  shows a cross-sectional view of one of the middle telescoping rings taken along line  4 - 4  in  FIG. 1 . In this particular implementation, though it is not required in every implementation, the sidewalls  42  of each of the middle telescoping rings  10 ,  12  and  14  include an inner curled portion  44 , an outer curled portion  46 , a stopper portion  48 , an angled inner sidewall  47  and an inner groove  45 . In the collapsed position, the outer curled portion  46  of a smaller middle telescoping ring fits into the inner groove  45  of the adjacent larger telescoping ring and rests against the stopper portion  48  of the larger telescoping ring. For example, the outer curled portion  46  of ring  12  rests against the stopper portion  48  and within the inner groove  45  of ring  10 . 
   When the telescoping cover  6  is expanded, the pressure exerted by gripping and pulling on the cover telescoping member  16  causes the outer curled portion  46  of a smaller middle telescoping ring to pop out of the inner groove  45  of the adjacent larger telescoping ring, slide against the angled sidewall  47  of the larger telescoping ring and interlock with the inner curled portion  44  of the larger telescoping ring. For example, the outer curled portion  46  of telescoping ring  12  pops out of the inner groove  45  of telescoping ring  10 , slides against the angled sidewall  47  of telescoping ring  10  and interlocks with the inner curled portion  44  of telescoping ring  10 . The interlocking curled portions  46  and  44  and the ramped sidewall  47  provide enough resistance to maintain the cover  6  in the extended position. In order to collapse the cover, pressing on the cover telescoping member  16  provides enough pressure to overcome the resistance and cause the outer curled portion  46  of the smaller middle telescoping ring to slide back along the ramped sidewall  47  of the adjacent larger middle telescoping ring. The outer curled portion  46  of the smaller telescoping ring then comes into contact with the stopper portion  48  of the larger telescoping ring and pops into the inner groove  45  of the larger telescoping ring. 
   The base telescoping ring  8  may include an inner curled portion  44 , an angled sidewall  47 , an inner groove  45  and a stopper portion  48 , but the outer curled portion  46  is not necessary. Conversely, the cover telescoping member  16  may include an outer curled portion  46 , but the inner curled portion  44 , angled sidewall  47 , inner groove  45  and stopper portion  48  are not necessary. 
   The inner curled portions  44 , the outer curled portions  46 , the inner grooves  45 , and the angled sidewalls  47  could extend all the way around the telescoping ring members in order to protect the electrical device from the elements.  FIG. 8  shows a front plan view of the electrical device cover  2  in the closed position and  FIG. 9  is a cross-sectional view along line C-C in  FIG. 8 . As shown in  FIG. 9 , the interlocking curled portions of the telescoping ring members enhance the shielding of the electrical device from the elements, such as rain  92 . 
   The stopper portions  48  may extend all the way around the telescoping ring members. Alternatively, the stopper portions  48  may extend along a section of two of the sides of each of the telescoping ring members, as shown in  FIG. 2 . The stopper portions  48  may alternatively extend along one, three or all four of the sides of each of the telescoping ring members. 
   A number of modifications may be made to the particular implementation shown in  FIGS. 1-4  and described above. For example, the telescoping portions of the cover  6  may be made progressively larger rather than progressively smaller. Yet another modification that is contemplated includes a cover assembly where the base is expandable and the cover is not expandable or where both the base and the cover are partially expandable. 
   An implementation with an expandable base and progressively larger telescoping portions is shown in  FIGS. 5-7 . The base  104  comprises a base member  108  and a plurality of inter-fitting, telescoping rings  106 ,  107  and  109 . The cover  160  is attached to the outermost telescoping ring  106 . 
   As an alternative to the interlocking curled portions  44  and  46  of the telescoping ring members  10 ,  12  and  14 , the telescoping members may be joined by a flexible material such as a rubber material. For example, as shown in  FIGS. 10-12 , the electrical device cover assembly  200  includes a base  204  and a cover  206 . The cover  206  of this particular implementation includes a plurality of telescoping members. Specifically, the cover  206  may include a base telescoping ring  208 , a plurality of middle telescoping rings  210  and  212  and a cover telescoping member  216 . Each telescoping member has a smaller diameter than the previous telescoping member and the smaller telescoping members fit within the bigger telescoping members. Between each telescoping member  208 ,  210 ,  212  and  216  is disposed a flexible connector  211 ,  213  and  215 . The flexible connector is a thin, flexible component between the sections that allows for bending. It is contemplated that the flexible connector may be formed of thin plastic, rubber or other appropriate material. Depending upon the material selected to form the flexible connector, the cover  206  may be configured to remain in the extended position by virtue of the nature of the material that comprises the flexible connectors  211 ,  213  and  215 . This would be similar to the way a flexible storage container like the “Collapsable Containers” made by Rubbermaid®, remain erect due to the nature of the plastic material used to form them. One of ordinary skill in the art of plastics molding will understand how to mold an appropriate cover material that can stand erect yet collapse when desired. This particular implementation may also include a clip  220  and a notch  222  to assist the cover in remaining closed if the material selected for the flexible material is not sufficiently rigid. In order to maintain the collapsed position, the notch  222  may be inserted into a hole  224  in the clip  220 , as shown in  FIG. 10 . The partial break-away view of  FIG. 12  shows how the plug  225  and the cord  226  can be contained within the device cover  200 . The cord exits the cover  200  through a cord opening  227 , as previously described relative to another implementation. 
   In all of the specific examples in  FIGS. 1-12  the electrical device covers shown are rectangular. However, any other shape could be used. For example, the electrical device cover could be square, circular or oval. Those of ordinary skill in the art will readily be able to adapt the examples disclosed herein to other shapes. 
   In yet another implementation, the electrical device cover assembly includes a round base (not shown) and a round cover  306  shown in  FIGS. 13-14 . The cover  306  may include a plurality of telescoping members. Specifically, the cover  306  may include a base telescoping ring  308 , a plurality of middle telescoping rings  310  and  312  and a cover telescoping member  316 . Each telescoping member has a smaller diameter than the previous telescoping member and the smaller telescoping members  316 ,  312  and  310  fit within the bigger telescoping members  312 ,  310  and  308 , respectively. In this implementation, the cover  306  is expanded using a twisting motion. Telescoping members  310 ,  312  and  316  includes grooves  330  on the outer sidewalls. Telescoping members  308 ,  310  and  312  include notches  332  on the inner sidewalls. The notches  332  on telescoping members  308 ,  310  and  312  fit within the grooves  330  on the telescoping members  310 ,  312  and  316 , respectively. The twisting motion allows the notches  332  to travel along the grooves  330 , thus expanding the cover  306 . 
   In yet another implementation, the telescoping members are roughly the same size and formed of a flexible material, such as rubber or thin plastic. The telescoping members are essentially stacked on top of each other in the collapsed position. In order to maintain the collapsed position, a clip, such as the clip  220  shown in  FIGS. 10-12  could be used. 
   It will be understood that implementations are not limited to the specific components disclosed herein, as virtually any components consistent with the intended operation of a method and/or system implementation for an electrical outlet cover may be utilized. Accordingly, for example, although particular shapes and sizes of electrical outlet cover assembly components may be disclosed, such components may comprise any shape, size, style, type, model, version, class, grade, measurement, concentration, material, weight, quantity, and/or the like consistent with the intended operation of a method and/or system implementation for an electrical outlet cover may be used. 
   In places where the description above refers to particular implementations of electrical device cover assemblies, it should be readily apparent that a number of modifications may be made without departing from the spirit thereof and that these implementations may be applied to other cover assembly types. The accompanying claims are intended to cover such modifications as would fall within the true spirit and scope of the disclosure set forth in this document. The presently disclosed implementations are, therefore, to be considered in all respects as illustrative and not restrictive, the scope of the disclosure being indicated by the appended claims rather than the foregoing description. All changes that come within the meaning of and range of equivalency of the claims are intended to be embraced therein.
