In this aspect, the slide is movable between the first position and the second position to selectively enable the modular power component to be retained within the body when the slide is in the first position and to selectively enable the modular power component to be removed from the body when the slide is in the second position.
In some implementations the slide is movable from the first position to the second position from outside the body via an aperture in the body.
In another aspect a power system includes a body, a chassis disposed within the body, the chassis having a plurality of slots in each of a plurality of modular power component receiving areas, a plurality of modular power components supported by the chassis in the modular power component receiving areas, the modular power components having power connectors extending through the slots, and a power distribution system disposed below the chassis and in electrical communication with the power connectors of each of the plurality of modular power components. In this aspect, a first subset of the slots in a first of the receiving areas are arranged to correspond with the power connectors of a first of the modular power components when the first of the modular power components is oriented in a first direction, and wherein a second subset of the slots in the first of the receiving areas are arranged to correspond with the power connectors of the first of the modular power components when the first of the modular power components is oriented in a second direction.
In some implementations the first direction is 180 degrees rotated from the second direction.
In certain implementations, at least one slot of the first subset of slots is also included in the second subset of slots.

In some implementations the first and second friction elements are serrated teeth.
In certain implementations, the first and second friction elements are bumps and detents.
This disclosure is based, at least in part, on the realization that it is desirable to provide a recessed power system that is easy to install into a surface, is able to be positioned to be flush with the surface when not in use, and that is easily reconfigurable using modular elements and power components.
Overview
To return the modular power component 18 to the retracted position (move from the extended position to the retracted position), the user will push on the top surface 14 of the modular power component 18 close to the opposite end 22, to cause the modular power component to rotate back into the housing 12 of power system 10. This causes the top surface of the modular power component to become flush with the rest of the top surface of power system 10.
A supporting undersurface 28 extends around a periphery of the power system and is configured to engage a mounting surface of an object to enable the body to sit within an aperture created in the mounting surface. For example, an aperture may be created in a top surface of a desk, table, or other flat surface where it is desirable to provide power. The body 16 of the power system 10 may be inserted into the aperture such that the supporting undersurface 28 sits flush with the top surface of the desk. Other surfaces which may be provided with power include horizontal surfaces such as dining surfaces, for example for use in cafeterias or cafes, and vertical surfaces such as on furniture, e.g. as shown in
As discussed in greater detail below, modular power components 18 are designed to be individually inserted into the body 16 of the power system in two orientations. For example, as shown in
Retaining Bracket
In one implementation, the body 16 includes friction elements 32 formed at one or more locations around its perimeter. In the example shown in
The retaining bracket 30 has corresponding friction elements (not shown) which engage the friction elements 32 on the body 16 of the power system. For example, where the friction elements 32 on the body are formed as a set of serrated teeth, the friction elements on the retaining bracket would likewise be formed as sets of serrated teeth to mesh with and engage the friction elements 32 on the body. Where the friction elements 32 on the body are formed as a set of detents, the friction elements on the retaining bracket would be formed as a set of bumps to fit within and engage the detents forming friction elements 32 on the body.
In operation, the power system 10 is inserted into an aperture in a flat surface such as a table top, and the retaining bracket is slid up around the body 16 from the bottom to encircle the body of the power system. As the retaining bracket 30 is slid upward, the friction elements on the retaining bracket engage the friction elements 32 on the body 16 to prevent the bracket from slipping back off of power system 10. The retaining bracket 30 is thus pushed onto the body 16 until an upper surface 34 of the retaining bracket is adjacent a lower surface of the flat surface. The friction elements 32 on the body and the friction elements on the retaining bracket cooperate to hold the bracket adjacent the lower surface of the table to hold the body of the power system within the aperture.
In an implementation, the retraining bracket 30 also includes spring tabs 36 which extend above the top surface 34 of the retaining bracket. The spring tabs 36 are designed to engage the lower surface of the flat surface when the retaining bracket is adjacent the lower surface of the table to pull the supporting undersurface 28 of the edge of the body 16 into secure engagement with the top surface of the table. By providing the spring tabs 36, the retaining bracket 30 may securely hold the power system within the aperture even if there is some minor discrepancy between the thickness of the table top and the possible locations of the retaining bracket given the placements of the detents on the body 16 relative to the undersurface 26.
In an implementation the friction elements 32 are provided on tabs 38 formed on body 16 which may flex inward into the body 16 to release engagement between the friction elements 32 on the body 16 and the friction elements on the retaining bracket. Tabs 38, in this implementation, facilitate release of the retaining bracket 30 from the body, for example if the body is to be removed from the flat surface (e.g. table top) in which it has been mounted.
Power in-Feed and Connectors
Other configurations are likewise possible. For example,
Although the implementation shown in
Because male and female connectors are identically shaped, it is possible for two female connectors to be connected together. However, as discussed below, the male and female connectors have differently numbers of electrical prongs extending from a surface of the connector which prevents power from being transferred between mated female connectors.
In addition, to prevent two female connectors from accidentally being physically joined together, or to prevent two male connectors from accidentally being joined together, in one implementation the male connector 46M and female connector 46F additionally include tab 52 and indent 54 which are oppositely located on the female and male versions of the connector 46. In one implementation, as shown in
When the female connector of
In addition to the differing location of the tab and indentations, the female connector shown for example in
The male connector, by contrast for example as shown in
In an implementation, ground contact 56 of female connector 46F extends from recess 50 of the female connector. Likewise, ground contact 56 and hot and neutral contacts 58 of male connector extend from recess 50 of the male connector. ground slot 60 and hot/neutral slots 62 are formed in protrusion 48 in both male and female versions of the connector.
In one implementation the ground contact 56 is provided to be longer than the hot and neutral contacts 58 to enable ground contact 56 to electrically connect with ground contact 65 of a mating connector when the ground contact 56 and hot/neutral contacts 58 extend through ground slot 60 and hot/neutral slots 62 of the mating connector.
In one implementation, magnets 68 are provided on either side of protrusion 48 and recess 50 to provide attractive force to cause mating pairs of connectors to be attractively coupled when placed in proximity of each other. In one implementation one of the magnets has a south polarity and the other of the magnets has a north polarity. Magnets 68 may be formed from neodymium or other permanently magnetic material. In another implementation, magnets 68 are electromagnetic and are attractive when power has been connected to the power system.
Power Distribution System
Optionally, in an implementation, an overcurrent protection circuit 82 is connected between the power system power source and the power conductors 50A-50E. The overcurrent protection circuit 82 is configured, in an implementation, to disconnect power to one or more of the power conductors 50A-50E upon detection of dangerous conditions on the one or more power conductors. A reset button 84 (see
In the implementation shown in
As shown in
By providing connector slots that are symmetric about a center line, a set of three connector prongs from modular power component 18 are able to selectively engage a first set of connectors 80A, 80B, 80C, or a second set of connectors 80C, 80D, 80E depending on the orientation of the modular power component within the modular power supply. Accordingly, the same modular power component can be inserted onto the chassis and provide power at the surface of the power system in two orientations. Since each raised connector area 74 has a set of five slots, the orientation of each modular power component is independent of the orientation of the other modular power components.
Although an implementation with five power conductors (2 hot, 2 neutral, and 1 ground) has been shown, other numbers of power conductors may be used in other implementations. For example, an implementation may include two ground conductors. Likewise, although in the implementation shown in
In the implementation shown in
Although an implementation has been described in which brass bars are used to implement power conductors 80, in another implementation different types of connectors such as wires may be used to interconnect power received on power input cord 40 and contacts formed behind slots 88.
In an implementation, the chassis 72 provides several additional functions in addition to providing for power distribution. For example, as shown in
Further, the chassis 72 is configured to cause water spilled onto the power system to be directed away from the high voltage components. Particularly when the raised connector areas are occupied by modular power components, water will tend to drain away from the raised connector areas to drip down into the bottom of the body of the power system rather than being directed toward the power conductors 80. The body of the power system may be provided with drainage holes at the bottom surface if desired to allow moisture to run out of the body to prevent excessive water from pooling inside the body.
Modular Power Components
Each modular power component 18 has a frame 96 designed to support the modular power component. The frame 96 includes feet 78 supported by legs 98. Legs 98 extend down to straddle one of the raised connector areas 74 of chassis 72 when inserted into the power system.
Arms 100 extend up from frame 96 and include pivot 102. Pivot 102 supports the body of the module 18 to enable the body of the module to be rotated between the extended position shown in
The module 86 may be designed to provide high power, e.g. line power, in which outlet 24 in face 26 is formed as an AC simplex female receptacle, for example as shown in
Although several implementations have been described which are configured to provide outlets within the modular power system, additional accessories may be utilized as well with the modular power system. For example, as shown in
An example wirefree charging system 112 implemented as part of the power system is shown in
In one embodiment, the wire free charging system 112 is formed to have contact strips as shown and as described in one or more of U.S. Pat. Nos. 7,932,638, 7,982,436, 7,986,059, and/or U.S. Pat. No. 8,081,408, the content of each of which is hereby incorporated by reference. Specifically, in this implementation, the wirefree charging system is formed to have a first plurality of contact strips and a second plurality of contact strips which alternate in sequence. Different electrical potential is applied to the sets of contact strips. For example, charging potential of 5 volts may be applied to a first set of contact strips and ground potential may be applied to the second set of contact strips. The electrical contact strips alternate to form an electrically conductive pad having multiple electrical contact points.
To obtain wirefree charging power from the sets of contact strips, a handheld electronic device has a plurality of contacts on an exterior surface. The contacts engage the contact strips to receive electric power which is conveyed from the contacts to the charging system of the handheld electronic device.
Modular Power Component Locking System
In one implementation, an aperture is formed in the body of the power system to enable the position of the slide 114 to be manipulated from outside the body. By accessing the slide 114, a person can move the slide from the locked position to the unlocked position, or from the unlocked position to the locked position, to enable the modular power components to be selectively locked within the power system or to be removable from the power system. Optionally a key 116 may be used to engage the slide and control movement of the slide 114.
In one implementation, a cylinder 122 is connected to or forms a part of slide 114 (see
Face 124 of cylinder 122, in an implementation, has an aperture extending there-through to receive a key 116. Key 116 may be inserted into the aperture in cylinder 122 to enable the key to engage the slide 114 to pull the slide from the locked to the unlocked position. In one implementation the aperture 126 in cylinder 122 is slot-shaped and the key has a T-shaped end. The elongated portions of the T-shaped end pass through the slot shaped aperture 126 in cylinder 122. Once the T-shaped end has passed through cylinder 122, the key may be turned to cause the T-shaped end to engage a rear surface of the cylinder. When the key 116 is pulled, force will be exerted on the slide 114 to cause the slide 114 to be moved from the locked position shown in
To transition from the unlocked position to the locked position, the key 116 is removed from the aperture 126 and the protruding cylinder 122 is pushed back into the body 16 so that the front face 124 is once again approximately flush with the surface of the body.
In another implementation, the aperture in the cylinder is implemented as a key lock and, rather than extending through, the key 116 is inserted into the lock and turned to unlock the lock. In this implementation the cylinder may then pulled out to cause the slide to move within the body. Although several specific implementations have been described, other implementations may use other methods of causing a locking mechanism such as the slide to be moved within the body to selectively engage/disengage the modular power components.
A number of implementations have been described. Nevertheless, it will be understood that additional modifications may be made without departing from the scope of the inventive concepts described herein, and, accordingly, other implementations are within the scope of the following claims.
This application claims priority to U.S. Provisional Application No. 61/985,766, filed Apr. 29, 2014, entitled Power System, the content of which is hereby incorporated herein by reference.
