A shutter assembly is for an electrical receptacle. The electrical receptacle has a base. The shutter assembly includes a first shutter and a second shutter each structured to be coupled to the base and rotate between a FIRST position and a SECOND position, and a slider assembly having a number of slider members each structured to be coupled to the base. The number of slider members includes only one single slider member structured to slide between a THIRD position and a FOURTH position and engage each of the first shutter and the second shutter. Rotation of both of the first shutter and the second shutter from the FIRST position to the SECOND position cooperatively drives the one single slider member from the THIRD position to the FOURTH position in order to provide access through the base.

Description

BACKGROUND

Field

The disclosed concept relates generally to electrical apparatus and, more particularly, to electrical apparatus such as electrical receptacles. The disclosed concept also relates to shutter assemblies for electrical receptacles.

Background Information

Electricity is often provided to electric devices via an electrical power cord including a plug, which is plugged into an electrical receptacle. Electrical receptacles typically include two sockets coupled together with a common housing, wherein each socket is adapted to receive the plug to thereby provide power via the corresponding power cord. More specifically, each plug includes a number of conductors commonly referred to as prongs, which are structured to be inserted into openings in the corresponding receptacle to engage electrical contacts.

A Ground Fault Circuit Interrupter (GFCI), for example, is a type of electrical receptacle with a safety feature for restricting electrical current in the event of a fault. That is, in the event that a short circuit or other fault is detected, the GFCI cuts off power to the electrical receptacle contacts until a user resets the GFCI. It is desirable to provide additional safety measures for electrical receptacles, for example in order to resist unintentional or undesired insertion of conductive objects into the openings of a receptacle to avoid electrical shock.

There is, therefore, room for improvement in electrical receptacles, and in shutter assemblies therefor.

SUMMARY

These needs and others are met by embodiments of the disclosed concept, which are directed to an electrical receptacle and a tamper-resistant shutter assembly therefor.

In accordance with one embodiment of the disclosed concept, a shutter assembly is provided for an electrical receptacle. The shutter assembly includes a base, a first shutter and a second shutter each coupled to the base and structured to rotate between a FIRST position and a SECOND position, and a slider assembly having a number of slider members each structured to be coupled to the base. The number of slider members includes only one single slider member structured to slide between a THIRD position and a FOURTH position and engage each of the first shutter and the second shutter. Rotation of both of the first shutter and the second shutter from the FIRST position to the SECOND position cooperatively drives the one single slider member from the THIRD position to the FOURTH position in order to provide access through the base.

In accordance with another embodiment of the disclosed concept, an electrical receptacle including a faceplate and the aforementioned shutter assembly is provided.

DESCRIPTION OF THE PREFERRED EMBODIMENTS

Directional phrases used herein, such as, for example, left, right, front, back, top, bottom, clockwise, counterclockwise, and derivatives thereof, relate to the orientation of the elements shown in the drawings and are not limiting upon the claims unless expressly recited therein.

As employed herein, the statement that two or more parts are “coupled” together shall mean that the parts are joined together either directly or joined through one or more intermediate parts.

As employed herein, the term “number” shall mean one or an integer greater than one (i.e., a plurality).

FIGS. 1 and 2 are isometric and partially exploded isometric views, respectively, of an electrical apparatus (e.g., without limitation, electrical receptacle 2), in accordance with one non-limiting embodiment of the disclosed concept. The electrical receptacle 2 has a faceplate 4 and a number of shutter assemblies (e.g., two shutter assemblies 100,200 are shown in FIG. 2). Although two shutter assemblies 100,200 are shown in FIG. 2, only the shutter assembly 100 will be described in detail herein, for ease of illustration and economy of disclosure. However, it will be appreciated that the shutter assembly 200 is configured substantially the same, and functions substantially the same, as the shutter assembly 100. The faceplate 4 has two pairs of openings (e.g., rectangular and T-shaped openings 6,8, and rectangular and T-shaped openings 16,18). The T-shaped openings 8,18 are to allow the electrical receptacle 2 to accommodate a 20 amp electrical plug having perpendicularly oriented blade members. See, for example, blade members 400,500 in FIGS. 9A-9C. As will be discussed below, the shutter assemblies 100,200 provide a mechanism to substantially ensure that only proper electrical plugs are able to be extended through the faceplate 4 and shutter assemblies 100,200, and into electrical contacts of the electrical receptacle 2. Accordingly, the disclosed shutter assemblies 100,200 improve operator safety.

FIGS. 3 and 4 show isometric and exploded isometric views, respectively, of the shutter assembly 100. The shutter assembly 100 includes a base 102 and a pair of shutters 104,114 each coupled to the base 102. In one example embodiment, the base 102 is made of an insulative thermoplastic material, and is coupled to the faceplate 4 (FIGS. 1 and 2) of the electrical receptacle 2 (FIGS. 1 and 2). The shutters 104,114 are each structured to rotate between a FIRST position (shown in FIG. 3) and a SECOND position (shown in FIGS. 8A-9C). When each of the shutters 104,114 rotates from the FIRST position to the SECOND position, each of the shutters has a corresponding axis of rotation 106,116 and a distal portion 108,118 located opposite and distal the corresponding axis of rotation 106,116. The shutter assembly 100 further includes a slider assembly 120 having a number of slider members 122,142 and a number of biasing elements (e.g., springs 150,152). Although the shutter assembly 100 is shown and described in association with two slider members 122,142, it will be appreciated that in a suitable alternative shutter assembly, only one single slider member (e.g., without limitation, the slider member 122) may be employed, with departing from the scope of the disclosed concept.

Only one single slider member (e.g., the slider member 122) is structured to slide between a THIRD position (FIG. 3) and a FOURTH position (FIGS. 8A-9C) and also engage each of the first shutter 104 and the second shutter 114. When the slider member 122 slides between the THIRD position and the FOURTH position, the slider member 122 slides on a first axis 160. The second slider member 142 is structured to slide between a FIFTH position, shown in FIGS. 3 and 5A-6C, and a SIXTH position shown in FIGS. 9A-9C. When the second slider member 142 slides between the FIFTH position and the SIXTH position, the second slider member 142 slides on a second axis 162 perpendicular to the first axis 160. As will be discussed in greater detail below, rotation of both of the shutters 104,114 from the FIRST position to the SECOND position cooperatively drives the one single slider member 122 from the THIRD position to the FOURTH position in order to provide access through the base 102.

The slider member 122 has a generally U-shaped frame portion 124 and a plurality of blocking portions 126,128 extending from the frame portion 124. The frame portion 124 has a pair of opposing, and generally parallel legs 130,132, and a middle portion 134 extending between the legs 130,132. It will be appreciated that when the first and second shutters 104,114 are in the SECOND position, the respective distal portions 108,118 are located between the first and second legs 130,132 of the slider member 122. The first blocking portion 126 extends outwardly from the first leg 130 substantially toward the slider member 142. The second blocking portion 128 is spaced from, and located opposite and distal to the middle portion 134. The first shutter 104 is substantially located between the second slider member 142 and the second shutter 114. Furthermore, as shown in FIG. 4, the second blocking portion 128 is located substantially perpendicular to the first and second legs 130,132 of the frame portion 124. The springs 150,152 are each coupled to and extend outwardly from a respective one of the slider members 122,142, for purposes that will be discussed below. In one example embodiment, the first spring 150 is substantially equidistant from the first leg 130 and the second leg 132.

FIGS. 5A-5C show different views of the shutter assembly 100 with a blade member 300 partially inserted. As shown, the first shutter 104 has been rotated to the SECOND position. However, as shown most clearly in FIGS. 5B and 5C, the blade member 300 is engaged with the second blocking portion 128 of the slider member 122 and is prevented from moving through the shutter assembly 100. It will be appreciated that in this position, e.g., a position wherein the single slider member 122 is still in the THIRD position and has generally not been moved at all, the blade member 300 is blocked from having access through the shutter assembly 100, e.g., and into an electrical contact of the electrical receptacle 2 (FIGS. 1 and 2). As such, when only the first shutter 104 rotates from the FIRST position to the SECOND position, the second blocking portion 128 blocks access through the base 102 proximate the first shutter 104. Accordingly, as the electrical receptacle 2 (FIGS. 1 and 2) is not intended to accommodate only one single blade member at a given time, or one single probe member of any kind at a given time, the shutter assembly 100 thus provides advantageous protection to operators who might attempt to do this, e.g., insert only one single probe member, whether intentionally or otherwise. Stated differently, the shutter assembly 100 makes the electrical receptacle 2 (FIGS. 1 and 2) safer because a user cannot simply insert an object that is not intended to be inserted, through the shutter assembly 100.

FIGS. 6A-6C show different views of the shutter assembly 100 with another blade member 400 partially inserted. As shown most clearly in FIG. 6B, the second shutter 114, which has a bulbous portion 115 in an interior of the shutter assembly 100, has been moved into engagement with the single slider member 122. However, as can be appreciated, further insertion of the blade member 400, e.g., through the shutter assembly 100 and into engagement with an electrical contact of the electrical receptacle 2 (FIGS. 1 and 2), is prevented by virtue of an engagement between the first blocking portion 126 of the slider member 122 and the first shutter 104. That is, rotation of the second shutter 114 from the FIRST position toward the SECOND position without rotation of the first shutter 104 drives the first blocking portion 126 into the first shutter 104 in order to prevent the slider member 122 from sliding from the THIRD position to the FOURTH position.

As depicted in FIGS. 6A-6C, no additional blade members, such as blade members from an electrical plug, have been inserted proximate the first shutter 104. As a result, the first blocking portion 126 of the slider member 122 moves into engagement with the first shutter 104, and the first shutter 104 thus prevents the slider member 122 from sliding to the right, from the perspective of FIG. 6C. If the slider member 122 does not slide to the right, from the perspective of FIG. 6C, then the second shutter 114 cannot fully rotate to the SECOND position (FIGS. 8A-9C). Thus, the blade member 400 is prevented from passing through the shutter assembly 100. This improves safety proximate the second shutter 114 for the same reasons discussed above with respect to FIGS. 5A-5C and the blade member 300.

FIGS. 7A-7C show different views of the shutter assembly 100 with another blade member 500 partially inserted, and oriented generally perpendicular to the orientation of the blade members 300,400, discussed above. As shown most clearly in FIG. 7B, the blade member 500 has partially moved the first shutter 104 toward the SECOND position, and has further not even reached engagement with the second blocking portion 128 of the slider member 122. For the same reasons discussed above with respect to the blade member 300 being inserted into the shutter assembly 100 in isolation, the slider member 122 has generally not been moved at all, or at least to the right, from the perspective of FIG. 7B. As such, when the second shutter 114 does not rotate from the FIRST position to the SECOND position and the second slider member 142 slides from the FIFTH position toward the SIXTH position, the second slider member 142 slides into engagement with the first slider member 122 in order to prevent access through the base 102 proximate the second slider member 142. Stated differently, when the blade member 500 moves into engagement with the second slider member 142 without a corresponding blade member being inserted proximate the second shutter 114, the blade member 500 drives the second slider member 142 into engagement with the second leg 132 of the first slider member 122. This engagement prevents the second slider member 142 from fully sliding to the SIXTH position. Accordingly, this prevents the blade member 500 from passing through shutter assembly 100 when the second shutter 114 has not been moved to the SECOND position.

FIGS. 8A-8C show different views of the shutter assembly 100 with blade members 300,400 of an electrical plug, such as a 15 amp plug, inserted entirely through the shutter assembly 100. As shown most clearly in FIGS. 8B and 8C, the shutters 104,114 are in the SECOND position. Accordingly, it will be appreciated that when the blade members 300,400 have both been inserted, the first shutter 104 moves to the SECOND position, thus eliminating the prior blocking engagement between the first blocking portion 126 of the slider member 122 and the first shutter 104. As such, there is nothing to inhibit the slider member 122 from sliding to the right, from the perspective of FIGS. 8B and 8C. That is, with the first shutter 104 moving toward the SECOND position, and eliminating the potential engagement between the first blocking portion 126 and the distal portion 108 of the first shutter 104, the bulbous portion 115 of the second shutter 114, which is driven by the blade member 400, is free to rotate to the SECOND position and drive the slider member 122 to the right. Once the slider member 122 has been driven to the right, from the perspective of FIGS. 8B and 8C, the second blocking portion 128 of the slider member 122 no longer blocks access through the shutter assembly 100. Compare, for example, the position of the second blocking portion 128 in FIG. 5B and FIG. 8B. Thus, operators attempting to insert objects into the electrical receptacle 2 (FIGS. 1 and 2) are provided with a beneficial layer of protection wherein only proper insertion through both of the openings 6,8 of the faceplate 4 will permit passage through the shutter assembly 100.

Similarly, FIGS. 9A-9C show different views of the shutter assembly 100 with blade members 400,500 of an electrical plug, such as a 20 amp plug, inserted entirely through the shutter assembly 100. As shown, the blade member 500 of the 20 amp plug is oriented perpendicular to the blade member 400 of the 20 amp plug. It will be appreciated that this blade member 500 would be configured to be inserted through the T-shaped openings 8,18 of the faceplate 4 (FIGS. 1 and 2). As shown most clearly in FIG. 9B, both shutters 104,114 have been moved to the SECOND position. Accordingly, in a similar as discussed above with the blade members 300,400 in FIGS. 8A-8C, with the first shutter 104 rotated to the SECOND position, the first blocking portion will not engage the distal portion 108 of the first shutter 104. As a result, with the first blocking portion 126 not engaging the first shutter 104, the bulbous portion 115 of the second shutter 114, which is driven by the blade member 400, is free to drive the slider member 122 to the right, from the perspective of FIGS. 9B and 9C. With the slider member 122 having slid to the right, the second blocking portion 128 (see FIG. 9B) and the second leg 132 (not shown in FIG. 9B, but see, for example, FIG. 7B) of the slider member 122 correspondingly slide to the right. As shown in FIG. 9B, the second blocking portion 128 does not block access for the blade member 500, and the second slider member 142, which is no longer blocked by the second leg 132 (not shown in FIG. 9B) of the slider member 122, has fully slid to the SIXTH position. Both blade members 400,500 are thus together able to be extended through the shutter assembly 100.

Additionally, the shutter assembly 100 is advantageously provided with a mechanism for the slider members 122,142 to return to the THIRD and FIFTH positions, respectively. More specifically, as shown in FIG. 9B, when the slider member 122 is in the FOURTH position, the spring 150 biases the slider member 122 toward the THIRD position. As such, when the blade members, be it the blade members 300,400, or the blade members 400,500, are together removed from the shutter assembly 100, the spring 150 drives the slider member 122 from the FOURTH position to the THIRD position. Similarly, when the slider member 142 is in the SIXTH position (FIG. 9B), the spring 152 (not shown in FIG. 9B) biases the slider member 142 toward the FIFTH position. Thus, when the blade members 400,500 are together removed from the shutter assembly 100, the spring 152 drives the slider member 142 from the SIXTH position (FIG. 9B) to the FIFTH position.

While the disclosed concept has been described in detail herein in accordance with the shutter assemblies 100,200, it will be appreciated that suitable alternative configurations of shutter assemblies are contemplated. For example and without limitation, while the disclosed concept has provided for both of the shutters 104,114 rotating in the same direction when moving from the FIRST position to the SECOND position (e.g., either both rotate clockwise or both rotate counterclockwise when moving from the FIRST position to the SECOND position), it is contemplated that shutters in a suitable alternative shutter assembly (not shown) may rotate in different directions when moving from FIRST to SECOND positions.

Accordingly, it will be appreciated that the disclosed concept provides for an improved (e.g., without limitation, safer) electrical receptacle 2 and shutter assembly 100,200 therefor, in which a pair of shutters 104,114 and a slider assembly 120 substantially ensure that the electrical receptacle 2 is used properly. More specifically, the shutter assemblies 100,200 substantially minimize and/or eliminate the possibility that a user might insert a single probe member through a single one of the openings 6,8,16,18 of the faceplate 4, and into an electrical contact of the electrical receptacle 2. This safety improvement substantially reduces the possibility for electrocution.

These benefits are provided in part because, when only one of the shutters 104,114 rotates from the FIRST position to the SECOND position, a slider member 122 of the slider assembly 120 is maintained in a THIRD position, thus preventing access through the shutter assembly 100. As a result, passage through the entire shutter assembly 100 (e.g. and the shutter assembly 200) can generally only be provided when both of the shutters 104,114 are moved from a FIRST position to a SECOND position. This protects operators from situations where they might intentionally, or inadvertently, insert only single probe members into one of the shutters 104,114. Specifically, in these situations the single probe members would be prevented from passage through the shutter assembly 100, in a manner described above.

While specific embodiments of the disclosed concept have been described in detail, it will be appreciated by those skilled in the art that various modifications and alternatives to those details could be developed in light of the overall teachings of the disclosure. Accordingly, the particular arrangements disclosed are meant to be illustrative only and not limiting as to the scope of the disclosed concept which is to be given the full breadth of the claims appended and any and all equivalents thereof
