DETAILED DESCRIPTION

[0022] The following discussion is directed to various embodiments. However, one of ordinary skill in the art will understand that the examples disclosed herein have broad application, and that the discussion of any embodiment is meant only to be exemplary of that embodiment, and not intended to suggest that the scope of the disclosure, including the claims, is limited to that embodiment.

[0023] The drawing figures are not necessarily to scale. Certain features and components herein may be shown exaggerated in scale or in somewhat schematic form and some details of conventional elements may not be shown in interest of clarity and conciseness.

[0024] In the following discussion and in the claims, the terms “including” and “comprising” are used in an open-ended fashion, and thus should be interpreted to mean “including, but not limited to... Also, the term“couple” or“couples” is intended to mean either an indirect or direct connection. Thus, if a first device couples to a second device, that connection may be through a direct connection of the two devices, or through an indirect connection that is established via other devices, components, nodes, and connections. In addition, as used herein, the terms“axial” and“axially” generally mean along or parallel to a given axis (e.g., central axis of a body or a port), while the terms “radial” and“radially” generally mean perpendicular to the given axis. For instance, an axial distance refers to a distance measured along or parallel to the axis, and a radial distance means a distance measured perpendicular to the axis.

[0025] As previously described, un-used electrical outlets may be covered with an appropriate safety cover or plug (generally referred to herein as“safety plugs”) to prevent or reduce the risk of electric shock. For instance, such safety plugs are used to protect against the insertion of objects into the electrical connectors of an electrical outlet. In order to use the electrical outlet, one would first remove any safety plugs installed therein and then insert an electrical plug (e.g., for an electrically operated device or appliance). Flowever, once use of the electrical outlet is ceased, one might forget to reinsert the safety plug. Also, in some circumstances, the individual who removed the safety plug to access the electrical outlet may misplace the safety plug such that subsequent re-installation of the safety plug into the electrical outlet is prevented.

[0026] Accordingly, embodiments disclosed herein include safety plug assemblies for an electrical outlet (and methods related thereto) that allow the safety plugs to remain coupled to the electrical outlet (e.g., via the face plate, the adjacent wall, etc.) even when the safety plug is not inserted within the electrical connector of the electrical outlet. Thus, through use of the embodiments disclosed herein, the chances that a safety plug will not be reinstalled into an electrical outlet following use thereof are reduced.

[0027] Referring now to FIGS. 1 and 2, a safety plug assembly 100 according to some embodiments is shown. As will be described in more detail below, safety plug assembly 100 is configured to be secured to an electrical outlet (see e.g., electrical outlet 10 in FIG. 4). Generally speaking, safety plug assembly 100 includes a connector 102 and a plurality of safety plugs 1 10 coupled to the connector 102. As is best shown in FIG. 2, safety plug assembly 100 also includes a first or front side 100a and a second or back side 100b opposite the front side 100a.

[0028] Connector 102 comprises a first body member 104 including a central axis 105, and a pair of second body members 106 extending from the first body member 104. In this embodiment, first body member 104 includes a first or top end 104a, and a second or bottom end 104b opposite and spaced from the top end 104a along axis 105. In addition, first body member 104 includes a first side 101 and a second side 103 radially opposite the first side 101 about the central axis 105. In the front side view of FIG. 1 , the first side 101 is a right side of the first body member 104, and the second side 103 is a left side of the first body member 104.

[0029] Both of the second body members 106 extend radially outward (with respect to the central axis 105) from the first side 101 of first body member 104. In particular, each of the second body members 106 includes a first or proximal end 106a, a second or distal end 106b opposite the proximal end 106a. Second body members 106 each are mounted to the first side 101 of the first body member 104 at proximal ends 106a such that the distal ends 106b are spaced from the first body member 104 in a radial direction with respect to axis 105.

[0030] In addition, the second body members 106 are axially spaced from one another along the axis 105. In particular, in this embodiment one of the second body members 106 extends from first side 101 of first body member 104 at (or proximate to) top end 104a, and the other of the second body members 106 extends from first body member 104 at (or proximate to) bottom end 104b.

[0031] As best shown in FIG. 1 , the first side 101 of first body member 104 and the second body members 106 together define a receptacle 120. Receptacle 120 is open along one side, between the distal ends 106b of second body member 106. As will be described in more detail below, the receptacle 120 is configured to receive one or more outlet connectors of an electrical outlet therein, when the safety plug assembly is coupled to the electrical outlet during operations.

[0032] Referring now to FIGS. 1 -3, each of the safety plugs 1 10 includes a head 1 14 and a plurality of plug members (or extensions) 1 16 extending from head 1 14. Each of the plug members 1 16 extends from head on the front side 100a of safety plug assembly 100.

[0033] In this embodiment, there are two plug members 1 16 extending from the head 1 14 of each safety plug 1 10; however, the number, arrangement, and/or shape of the plug members 1 16 may be greatly varied in other embodiments. More particularly, the size, shape, arrangement of plug members 1 16 may be set based on the size, shape, arrangement, etc. of the contact openings of an electrical outlet (e.g., contact openings 14 shown in FIG. 4 and discussed below). Therefore, in various embodiments, the plug members 1 16 are arranged and designed such that the safety plugs 1 10 (namely the plug members 1 16) correspond and therefore engage with the contact openings of a given electrical outlet.

[0034] The head 1 14 of each safety plug 1 10 is coupled to first body member 104 of connector 102 via a corresponding elongate arm 1 12. Specifically, in some embodiments, each of the elongate arms 1 12 extend (e.g., radially) from second side 103 of first body member 104. In this embodiment, arm 1 12 may have the same thickness as connector 102 (including first body member 104 and second body members 106). In addition, as is best shown in FIGS. 2 and 3, in this embodiment, base 1 14 has a greater thickness than the corresponding arm 1 12; however, in other embodiments, head 1 14 may the same thickness as the corresponding arm 1 12.

[0035] Referring still to FIGS. 1 -3, in this embodiment, the connector 102 (including the body members 104, 106), safety plugs 1 10, and arms 1 12 may all be monolithically formed as a single piece, monolithic body. In addition, in some embodiments connector 102, safety plugs 1 10, and/or arms 1 12 may be formed from a dielectric material (e.g., plastic, rubber, etc.). In some embodiments, only some of the components of safety plug assembly 100 (e.g., safety plugs 1 10) may be constructed from a dielectric material. In addition, in this embodiment, body members 104, 106 of connector 102 may all lie within the same plane (e.g., an axially oriented plane that includes the central axis 105). Further, the material(s) making up safety plug assembly 100 (or at least some parts thereof) may be flexible, such that safety plug assembly 100 (or at least some parts thereof) may be elastically deformed (e.g., folded, rolled, etc.) without resulting in damage thereto. In particular, in this embodiment, arms 1 12 are flexible such that they may be freely rolled, folded, or otherwise deformed during operations to connect and disconnect safety plugs 1 10 from corresponding connectors of an electrical outlet. Also, safety plug assembly 100 may be transparent (or substantially transparent), opaque, or translucent in various embodiments. Safety plug assembly 100 may be any suitable color(s) or shade(s) in various embodiments (e.g., to match or correspond with the color or shade of the wall 15, electrical outlet 10, etc.). [0036] In addition, the safety plug assembly 100 may be manufactured via a variety of different methods. For instance, in some embodiments, safety plug assembly 100 may be manufactured via a pressing, molding (e.g., injection molding, press molding, etc.), additive manufacturing (e.g., three dimensional - 3D— printing), stamping, cutting, etc.

[0037] Referring now to FIGS. 4 and 5, during operations, safety plug assembly 100 is coupled to an electrical outlet 10 that is mounted to a support surface 15. Support surface 15 may comprise any suitable surface for supporting an electrical outlet. For example, in some embodiments support surface 15 may comprise a wall of a structure, a backsplash, a side of a cabinet, a base board, etc., and may be more simply referred to herein as“wall 15

[0038] Electrical outlet 10 includes a plurality of outlet connectors 12, each including a plurality of contact openings 14 that provide access to an electrical contact (not shown) which may be further coupled to a source of electricity. One or more (e.g., two in this embodiment) mounting screws 18 are inserted through front plate 13 and threadably engaged within corresponding receptacles 22 coupled to electrical outlet 10 (or to an electrical junction box 20 disposed within wall 15) to mount front plate 13 to wall 15. In this embodiment, mounting screws 18 are disposed proximate a top and bottom of the front plate 13; however, in other embodiments, mounting screws 18 may be disposed on other locations of front plate 13. For instance, in some embodiments, a single mounting screw 18 may be disposed at a central location of front plate 13, between electrical connectors 12.

[0039] As shown in FIGS. 4 and 5, during operations mounting screws 18 are loosened such that front plate 13 may be spaced from wall 15. Thereafter, connector 102 (including body members 104, 106) is slipped or inserted between front plate 13 of electrical outlet 10 and wall 15. As can be appreciated in FIGS. 4 and 5, the shape and arrangement of connector 102 allows body members 104, 106 to be inserted between wall 15 and front plate 13 without interfering or overlapping with mounting screws 18, outlet connectors 12, junction box 20, and/or other components of electrical outlet 10 that are disposed behind front plate 13. In particular, the outlet connectors 12 may be received within the receptacle 120 formed by first body member 104 and second body members 106 of connector 102. As best shown in FIG. 4, the outlet connectors 12 are received into the receptacle 120, through the opening formed between the distal ends 106b of second body members 106 along a generally radially oriented direction with respect to axis 105. Once connector 102 is positioned between front plate 13 and wall 15 as described, mounting screws 18 may be re-tightened so as to capture and compress connector 102 (including first body member 104 and/or second body members 106) between front plate 13 and wall 15. In particular, as shown in FIG. 5, connector 102 is engaged with (e.g., partially, wholly, etc.) with the front plate 13 of electrical outlet 10 along front side 100a of safety plug assembly 100, and connector 102 is engaged (e.g., partially, wholly, etc.) with the wall 15 along back side 100b of safety plug assembly 100.

[0040] Thus, in some embodiments connector 102 may be inserted between front plate 13 and wall 15 without completely removing mounting screws 18 from receptacles 22 and therefore without entirely removing front plate 13 from outlet 10. However, it should be appreciated that in some embodiments mounting screws 18 may be completely disengaged from receptacles 22 and front plate 13 may be removed from wall 15 so as to allow positioning of connector 102 during operations.

[0041] Referring specifically to FIG. 4, once connector 102 of safety plug assembly 100 is secured and captured between front plate 13 and wall 15, safety plugs 1 10 may be selectively coupled or engaged with outlet connectors 12. In particular, plug members 1 16 on each safety plug 1 10 may be inserted within the contact openings 14 on a corresponding one of the outlet connectors 12. As the safety plugs 1 10 are maneuvered to engage plug members 1 16 with contact openings 14, arms 1 12 may elastically bend, roll, or otherwise deform to accommodate the movement of safety plugs 1 10. In this embodiment, the contact friction between plug members 1 16 and contact openings 14 is sufficient to prevent undesired disengagement of safety plugs 1 10 from connectors 12 during operations. In addition, because safety plug assembly 100 (including safety plugs 1 10, connector 102, and arms 1 12) are constructed from a dielectric material (e.g., plastic), electrical current is not conducted through safety plug assembly 100, even when plug members 1 16 are inserted within contact openings 14 as described above.

[0042] Thereafter, if access to one or both of the outlet connectors 12 is desired (e.g., such as to plug in an appliance or other electrical device), the safety plugs 1 10 (or at least one thereof) may be disengaged from the outlet connectors 12 thereby exposing contact openings 14. Because safety plugs 1 10 are secured to connector 102 via arms 1 12, and connector 102 is captured between front plate 13 and wall 15 as previously described, once safety plugs 1 10 are disengaged from electrical connectors 12, they may be supported and suspended adjacent electrical outlet 10 via arms 1 12. Thus, when use of electrical connectors 12 is no longer desired, safety plugs 1 10 are positioned adjacent to electrical outlet 10 such that they are prevented from being misplaced and are more likely to be re-engaged with electrical connectors 12.

[0043] Referring briefly to FIGS. 6 and 7, in some embodiments, some or all of the safety plugs 1 10 on safety plug assembly 100 may be replaced with safety plug 210. Safety plug 210 is similar, in some respects, to safety plugs 1 10, previously described. Thus, like features are described with the same reference numerals and the discussion below will focus on the features of safety plug 210 that are different from safety plug 1 10, previously described. In particular, in this embodiment, safety plug 210 comprises a head 214 in place of head 1 14. In this embodiment, head 214 is integrally or monolithically mounted to the corresponding arm 1 12, such as described above for head 1 14 (see e.g., FIG. 2). In addition, in this embodiment, head 214 has the same thickness as arm 1 12 (which in turn has the same thickness of body members 104, 106 of connector 102). Flowever, in some embodiments head 214 may have a greater or lesser thickness than the corresponding arm 1 12. Further, head 214 includes a plurality (two in this embodiment) of slots or apertures 217 extending therethrough.

[0044] In addition, safety plug 210 includes a separate plug 212 that includes a base 213 and a plurality of plug members 216 (which are generally the same as plug members 1 16, previously described) extending from the base 213. Plug 212 may be a commercially available safety plug for engagement with a corresponding electrical outlet (e.g., outlet 10).

[0045] During operations, plug 212 is installed onto head 214 of safety plug 210 by aligning and inserting the plug members 216 through apertures 217 until base 213 is engaged with head 214 along back side 100b (e.g., as shown in FIG. 6). Accordingly, the number, arrangement, size, shape, etc. of apertures 217 may be chosen so as to correspond with the number, arrangement, size, shape, etc. of plug members 1 16. Once safety plugs 212 are installed onto head 214, operations with safety plugs 210 are the same as those described above for safety plugs 1 10, and thus, a detailed description of these operations is not provided in the interest of brevity. However, during these operations, it should be appreciated that if one or both of the plug members 216 is damaged or severed (or if plug 212 is lost), a new plug 212 may be installed onto head 214 of safety plug 210 in the manner described above.

[0046] As previously described above and generally shown in FIGS. 1 and 4, the connector 102 of safety plug assembly 100 may form an open receptacle 120 such that the electrical connectors 12 of electrical outlet 10 may be inserted into receptacle 120 in a radial direction with respect to axis 105 and the front plate 13 of electrical outlet 10 may merely be loosened and not removed when installing connector 102 between front plate 13 and wall 15 during operations. However, in other embodiments, the connector 102 may define a fully enclosed (or closed) receptacle that is to receive the electrical connectors 12 during operations. Without being limited to this or any other theory, by receiving the electrical connectors 12 within a fully enclosed receptacle, the safety plug assembly 100 may be more securely engaged with the electrical outlet 10, so that accidental or unintentional removal of the safety plug assembly 100 from the electrical outlet 10 is prevented.

[0047] In particular, reference is now made to FIG. 8 which shows a safety plug assembly 200 according to some embodiments. Safety plug assembly 200 includes many of the same components and features as safety plug assembly 100. Thus, features of safety plug assembly 200 that are generally shared with safety plug assembly 100 are identified with the same reference numerals, and the discussion below will focus on the features of safety plug assembly 200 that are different from that described for safety plug assembly 100.

[0048] In particular, as shown in FIG. 8, safety plug assembly 200 includes a connector 202 in place of connector 102 (see e.g., FIG. 1 ). In addition, safety plug assembly 200 includes a plurality of safety plugs 110 coupled to connector 202 via a plurality of arms 112 as previously described above for safety plug assembly 100. Connector 202 is generally the same as connector 102, except that connector 202 defines a closed receptacle 220 in place of the receptacle 120. Specifically, connector 202 includes first body member 104 and second body members 106 extending from first body member 104 as generally described above. In addition, connector 202 includes a third body member 204 that extends between the distal ends 106b of second body members 106 in a generally parallel direction to the axis 105. Together, the first body member 104 (particularly, first side 101 of first body member 104), the second body members 106, and the third body member 204 define a closed receptacle 220.

[0049] Referring now to FIGS. 5 and 8, during operations the electrical connectors 12 of electrical outlet 10 are received within the receptacle 220. However, because receptacle 220 is closed via the third body member 204, front plate 13 is fully removed from the electrical outlet 10 so as to allow the electrical connectors to be inserted into and through the receptacle 220 (e.g., in a direction that extends perpendicularly to the page in the view of FIG. 8). Finally, once the connector 202 is installed about the electrical connectors 12, the front plate 13 may be replaced via mounting screws 18 as previously described. Thereafter, insertion of the safety plugs 110 within electrical connectors 12 may proceed in the same manner as described above for safety plug assembly 100.

[0050] Referring now to FIGS. 9-12, a safety plug assembly 300 according to some embodiments is shown. Generally speaking, safety plug assembly 300 is similar to the safety plug assembly 100 (FIG. 1 ) previously described above. Thus, features of safety plug assembly 300 that are generally shared with safety plug assembly 100 are identified with the same reference numerals, and the discussion below will focus on the features of safety plug assembly 300 that are different from safety plug assembly 100.

[0051] Generally speaking, safety plug assembly 300 includes a first or front side 300a and a second or back side 300b that correspond with the front side 100a and back side 100b, respectively, of safety plug assembly 100 (see e.g., FIG. 1 ). In addition, safety plug assembly 300 includes a connector 302 and a plurality of safety plugs 110 coupled to connectors 302 via a plurality of arms 112. Connector 302 is similar to connector 102 and includes a first body member 104 and the pair of second body members 106 as generally described above.

[0052] In addition, as is best shown in FIGS. 9 and 11 , connector 302 includes a plurality of catch members 320 coupled to first body member 101 along front side 300a of safety plug assembly 300. Each catch member 320 includes an abutment surface 324 that extends perpendicularly or normally relative to first body member 104. In other words, abutment surface 324 comprises a planar surface that extends in a direction that is parallel to a radius of axis 105. In addition, each catch member 320 comprises a ramped surface 322 that extends from the abutment surface 324 to the surface of first body member 101 on front side 300a of safety plug assembly 300. In particular, in some embodiments ramped surface 322 comprises a planar surface; however, in other embodiments, ramped surface 322 may comprise a curved surface (e.g., a convexly curved surface). Thus, in at least some embodiments, the catch members 320 may have a right-triangular shaped cross-section when viewed along axis 105.

[0053] Referring briefly now to FIGS. 13 and 14, during operations, catch members 320 may prevent or at least restrict the accidental withdrawal of the connector 102 from electrical outlet 10. In particular, in some embodiments, front plate 13 of electrical outlet 10 may comprise a peripheral lip 11. When installing, the safety plug assembly 300 onto the electrical outlet 10, the face plate 13 may only be loosened from the wall 15 such that connector 302 may be inserted therebetween as previously described (see e.g., the progression from FIG. 13 to FIG. 14). During these operations, the ramped surfaces 322 of catch members 320 may slide along the lip 11 until the abutment surfaces 324 are advanced past lip 11 and under front plate 13 (see e.g. FIG. 14). Thereafter, the front plate 13 may be re-secured to the electrical outlet 10 as previously described (via re-tightening the mounting screws 18 shown in FIG. 5). Flowever, once font plate 13 is compressed against connector 302 along front side 300a of safety plug assembly 300, withdrawal of the connector 302 from behind the front plate 13 (e.g., without loosening the plate 13 from support surface 15 and electrical outlet 10 as previously described) may be prevented by engagement of the abutment surfaces 324 of catch members 320 and lip 11 of front plate 13.

[0054] Referring again to FIGS. 9-12, arms 112 of safety plug assembly 300 may be generally the similar to that previously described above; however, in this embodiment, arms 112 may additionally include a hinge assembly 330. As will be described in more detail below, the hinge assembly 300 may allow bending or folding of the corresponding arm 112 during operations so as to enhance and facilitate engagement of the safety plugs 110 with the electrical connectors of an electrical outlet during operations (see e.g., electrical connectors 12 of electrical outlet 10 in FIG. 8, previously described above).

[0055] In this embodiment, hinge assembly 330 comprises a plurality of recesses or notches 332, 334 that generally reduce a thickness of the arm 112 so as to facilitate bending or folding of the arm 112 at the hinge assemblies 330 during operations. In particular, in this embodiments, arms 112 may each include one or more first notches 332 along front side 300a of safety plug assembly 300 (FIGS. 9 and 11 ) and one or more second notches 334 along back side 300b of safety plug assembly 300 (FIGS. 10 and 12). As best shown in FIGS. 13 and 14, the first notches 332 may be aligned with the second notches 334 along the length of arms 112 such that the thickness of the arms 112 is reduced both along first side 300a and second side 300b at the aligned notches 332, 334.

[0056] Thus, during operations, when one of the safety plugs 110 is maneuvered to engage with an electrical connector on an electrical outlet as described above, the corresponding arm 112 may bend or fold at the aligned notches 332, 334 so that a general curvature along the arm 112 is reduced. Without being limited to this or any other theory, by reducing a curvature of the arms 112 when the safety plugs 110 are inserted with the electrical connectors of a corresponding electrical outlet (see e.g., electrical connectors 12 and electrical outlet 10 in FIG. 8), may reduce the distance that arms 112 may project outward from the electrical outlet and/or the underlying support surface (see e.g., wall 15 in FIG. 8), so that there is a reduced chance that someone may accidentally engage with the arms 112 and thereby unintentionally withdrawal or disengage safety plug 110 from the electrical connector 12.

[0057] It should be appreciated that in some embodiments, hinge assembly 330 may comprise alternative structures or components (e.g., other than or in addition to notches 332, 334) for facilitating the bending or folding of arms 112 during operations. For instance, in some embodiments, hinge assemblies 330 may comprise a pinned connection.

[0058] Referring now to FIGS. 10 and 12, the connector 302 and arms 112 may include a plurality of tapered edges on back side 300b of safety plug assembly 300. In particular, second body members 106 may each include a leading tapered edge 308 at distal ends 106b and a pair of side tapered edges 306 extending between ends 106a, 106b. In addition, first body member 104 may include a first tapered edge 301 along first side 101 , and a second tapered edge 303 along second side 103. Further, arms 112 may each include a pair of tapered edges 312.

[0059] Referring now to FIGS. 10 and 12-14, during operations, as connector 302 is inserted between the front plate 13 and wall 15, the tapered edges, and particularly the leading tapered edges 308 on distal ends 106b of second body members 106 as well as the first tapered edge 301 along first side 101 of first body member 104 may prevent connector 302 from being caught or engaged on surfaces or components of electrical outlet 10 that are disposed under front cover 13. Rather, the angle of the tapered edges (e.g., again particularly tapered edges 308, 301 ) may allow connector 302 to generally deflect away from obstructions so as to allow the general insertion of connector 302 behind front plate 13 to continue.

[0060] In some embodiments, a safety plug assembly (e.g., safety plug assembly 100, 300) may be integrated with the front cover the electrical outlet (e.g., front cover 13). For instance, reference is now to FIG. 15, wherein a safety plug assembly 400 according to some embodiments is shown. Safety plug assembly 400 may share several features with safety plug assemblies 100, 300. As a result, features of safety plug assembly 400 that are shared with safety plug assemblies 100, 300 may be identified with the same reference numerals and the discussion below will focus on the features of safety plug assembly 400 that are different from safety plug assemblies 100, 300.

[0061] In particular, safety plug assembly 400 does not include a connector 102, 302 (see e.g., FIGS. 1 and 9). Rather, the arms 112 and safety plugs 110 are directly engaged with front cover 13 of electrical outlet 10. During operations, the safety plugs 110 are maneuvered so as to selectively engage the safety plugs 110 with the electrical connectors 12 of electrical outlet 10 in the same manner as previously described except that no connector 102, 302 is disposed between front cover and support surface 15, and arms 112 instead are deformed (e.g., folded, rolled) directly about front cover 13.

[0062] Embodiments disclosed herein include safety plug assemblies (e.g., safety plug assembles 100, 200, 300, 400) for electrical outlets that allow the safety plugs (e.g., safety plugs 110, 210) to remain coupled to the electrical outlet (e.g., via the face plate, the adjacent wall, etc.) even when the safety plug is not inserted within the electrical connector of the outlet. Thus, through use of the embodiments disclosed herein, the risk that a safety plug will not be reinstalled into an electrical outlet following use thereof is reduced.

[0063] While exemplary embodiments have been shown and described, modifications thereof can be made by one skilled in the art without departing from the scope or teachings herein. The embodiments described herein are exemplary only and are not limiting. Many variations and modifications of the systems, apparatus, and processes described herein are possible and are within the scope of the disclosure. Accordingly, the scope of protection is not limited to the embodiments described herein, but is only limited by the claims that follow, the scope of which shall include all equivalents of the subject matter of the claims. Unless expressly stated otherwise, the steps in a method claim may be performed in any order. The recitation of identifiers such as (a), (b), (c) or (1 ), (2), (3) before steps in a method claim are not intended to and do not specify a particular order to the steps, but rather are used to simplify subsequent reference to such steps.
