DETAIL DESCRIPTION OF THE PREFERRED EMBODIMENTS
The current invention includes an outlet device with position changeable feature which provides a simple means to all people to change the positions of all outlet-units as needed. Currently, all power strips or power tapes are normally fixed in an unchangeable position. Because, in the conventional market, all outlet-units are fixed at a certain position, some big size plugs cannot fit within the limited space, resulting in waste since people need to buy a second set of power strips or power tapes to achieve a proper electric connection with a power source for the devices that do not fit into the first power strip or tape.
The current invention offers a position changeable outlet device that lets people adjust the position of each outlet-unit so that all outlet-units can properly be used to make electric connection with an electric device. The position changeable features of the current invention means can be achieved by a variety of means that permit rotary or other movements/adjustments including those that involve a jumpable gap and/or parts that are extendable, foldable, extractable, connectable, disconnectable, retractable, expandable, addable, adjustable, bendable, overlapable, underlayable, assembleable, dis-assembleable, or flexible.
Also, the current invention's receiving socket sets preferably have their own contact means so no wiring is necessary to connect the socket sets with power bus means. This is an advantageous design because it offers people convenient and safe electric connection for all outlet-units to the bus means (as above discussed feature 15)
A detailed description of these features follows:
As shown in FIG. 1, an extendable outlet device (01) has housing-means (11) with a plurality of outlet-units (12) installed on the housing-means (11). Another device (14) which may be a light device, LED device, phone jack device, surge protector device, sensor device, switch device or other device available in the marketplace also can fit on the housing-means (11) to provide the outlet device with more features. Each of the outlet-units (12) may change position when a force is applied to the said housing-means (11) (13) and expand in another direction to make all outlet-units change position as desired.
As shown in FIG. 2, the outlet-units (25) (26) (27) are fitted within the track-means (20) in the same manner as the LED-unit (23) of the above-cited copending application Ser. No. 12/149,963, entitled “Removable LED light device.” Each of the outlet-units has three socket-set receiving areas to connect with a plug's three parts to enable delivery of an electric signal from the outlet-device to other electric items.
As shown in FIG. 3, the outlet device (03) includes two long housing-means (31) (33) and one short joint-means (32). Each of the housing means (31) (33) can be rotated to the left and right as needed. Each of the long housing means further has a plurality of outlet-units (38), other devices (34), switch means (35), or sensor means (39), or other any electric device (37). The joint means (32) has rotatable bus-means (not shown) within to deliver an electric signal from the housing means (31) to the next housing means (33).
As shown in FIG. 4, the outlet-device (04) has a plurality of outlet-units (43) (43′) (43′′) and other devices (42) on its track-means (40). The electric signal source is from a wall outlet (alternating current (AC)) so san electric cord (45) and plug (46) are provided to connect with the wall outlet to get the electric signal. The electric signal is supplied to the outlet-device (04) from the side hole (44) to an inner plurality of bus means (not shown), and each bus means connects with the contact means of each outlet-unit (43) (43′ (43′′). A safety curtain (47) (47′) (47′′) (47′′) fits within each space between the outlet-units (43) (43′) (43′′) (43′′′′) or other device (42) to prevent people from touching live wires which have a high voltage and high current. The safety curtain (47) (47′) (47′′) (47′′′′) can b made of a UL required material with extendable and foldable features so as to make sure that every space between the outlet-units will be covered by the safety curtain without any hole that allows people to touch the live wires under any situation. The extra-space or compartment (49) under the track-means (40) can offer space to store the electric-cord (45) and its plug (46) or other electric parts and components such as surge protection parts and accessories, or a switch, sensor, lighting, blue tooth device, PIR device, or motion sensor device to provide multiple functions for the outlet-device according to market requirements.
As shown in FIG. 5, the outlet device (05) includes track-means (50) with a plurality of outlet-units (53) (53′) and another device (54). Each outlet-unit (53) (53′) has a three socket-set receiving-areas with three corresponding resilient contact means to make an electric electrical connection with the device's bus-means (not shown) on the button of each outlet-unit. In this preferred embodiment, the resilient contact means is a solid cylinder-metal piece. The electric signal delivered from the bus-means (not shown) to each outlet-unit (53) (53′) needs to be very large so the contact means needs to be a solid cylinder metal piece so as to carry enough electric signal from one end to other end. If a metal spring is used, a big problem of results because the spring cross-section is way too small to allow the large amount of electric signal required. The other device (54) may be an LED light unit which has a plurality of LEDs (54′′) inside with a built-in circuit to connect with bus means and provide LED illumination with removable features as described in various ones of my copending applications cited above. The electric signal source of this preferred embodiment is a solar electric source (55) with output-ends (55′) (55′′) that connect with an electric cord (56) and in the track-means (50) though the hole of the track-means.
As shown in FIG. 6, a track-means (60) has three outlet-units (63) (63′) and (64) that fit within the track-means (60). The outlet-unit (64) has a socket set that is different from the standard type of the socket-set because it is for a special plug. This exemplifies how the current invention may be used for any kind of socket-set and special plugs available from the conventional market. It will also be appreciated that all other kinds of socket-set for different electric device may be provided, including socket sets that utilize a wall outlet, solar power, wind generator, electric signal generator (sound, audio, video), or equivalent electric signal source to supply power to another device to provide desired functions, any of which may still fall within the current invention's scope.
As shown in FIG. 7, the extendable outlet device (07) has a long housing means (72), short housing means (70), and joint means (71) with outlet-units (73) (73′) and other device (74). When the housing means (70) (72) or joint means (71) is expanded to be wider, the positions of all the related outlet-units (73) (73′) and other device (74) are changed accordingly.
As shown in FIG. 8, the outlet device (08) has a shape (80) with six outlet-units (81) (82) (83) (84) (85) (86) having their own contact-means (not shown) to connect with inner bus means. Each outlet-unit has a preferably clip-type (not shown) contact means so it can be clipped on the wall-thickness of the bus means (not shown). Each of the clip-type contact means can have a different angle so all outlet-units will have different orientation. These outlet-units will not rotated but can be replaced easily and change position while as needed because each contact means is a clip-type so it can be easily replaced by simple dis-assembly of the safety screw and re-assembly.
The embodiment of FIG. 9 is the same as that of FIG. 1 and FIG. 3, except that the outlet device (09) has a lot of different outlet-units (92) (96) (95) (94) with different functions achieved by connecting the outlet-units with inner buss-means to provide the proper functions.
As shown in FIGS. 10, 11, 12, a cylinder-type (10-2) (11-2) (12-2) contact-means is provided to deliver a large electric signal. The above-cited copending application Ser. No. 12/149,963, entitled “removable LED light device,” discloses a design for resilient conductive means I the form of a “metal spring” to supply an electric signal for delivery to an LED-unit. However, the metal spring is too thin with a very tiny cross-section to allow a large current to be delivered from end to end.
The current invention needs to deliver a large electric signal such as 110V, 60 Hz current with multiple thousand watts. Hence, the current invention utilizes a redesigned super heavy duty contact-means, conductive means, resilient conductive means with a large cross-section of the metal area to meet the safety standard. Hence, all of the metal piece joint-points have to have a sufficiently large cross-section area to provide the large electric signal.
As shown in FIG. 10, the conductive means (10-1) with socket-set receiving-area (10-3) is connected with a cylinder-type contact-means (10-2) incorporating a super heavy elastic, resilient conductive means to that keeps the best resilient properties to ensure the best electric connection with bus-means (not shown). The resilient conductive means (hereof, a metal spring (10-4)) offers strong elastic and resilient properties to the cylinder-type contact-means (10-2). The incoming plug means (not shown) will make electric connection with the conductive means (10-1) at the clip-type of receiving-areas (10-3).
As shown in FIG. 11, the conductive means (11-1) has a socket-set receiving-area (11-3) and connects with the cylinder-type of contact-means (11-2) having super heavy resilient conductive means to offer the best elastic properties and make good electric connection with the bus-means. The resilient conductive means (hereof a metal spring (11-4)) offers strong elastic and resilient properties to the cylinder-type contact-means (11-2). The incoming plug means (not shown) will make electric connection with the conductive means (11-1) at the clip-type of receiving-areas (11-3).
As shown in FIG. 12, the conductive means (12-1) has a socket-set receiving-area (12-3) and connects with the cylinder-type contact-means (12-2) having super heavy resilient conductive means to offer the best elastic properties and make good electric connection with bus-means. The resilient conductive means (metal spring (12-4)) offers strong elastic and resilient properties to the cylinder-type contact-means (12-2). The incoming plug means (not shown) will make electric connection with the conductive means (12-1) at the curved-type of receiving-areas (12-3).
FIG. 13 shows a cross-section of the second preferred embodiment, which has a track means (H1) having a geometric shape that allows the outlet-unit (H2) to fit within. The outlet-unit (H2) has socket-set receiving-areas (Re1) (Re2) (Re3) with resilient conductive means (SP1) (SP2) (SP3) to provides its own contact-means (CT1) (CT2) (CT3) with super perfectly resilient properties and enables the cylinder-type contact-means (CT1) (CT2) (CT3) to contact with the outlet device's bus-means (buss1) (buss2) (buss3) to deliver a large electric signal from an electric signal source (not shown) to the socket-set's receiving-areas (Re1)(Re2) (Re3). The outlet-unit (H2) has an edge (13-4) that fits within the trace means (H1)'s two walls (13-1) (13-2) to hold the outlet-unit in position tightly, while being removable along the trace-means (H1) elongate length. The outlet-unit (H2) will be easily moved within the two walls to a desired position as needed to accommodate different size plug means (not shown). It is not necessary to provide a rotatable outlet-unit for this easily removable outlet device.
FIG. 14 shows details of the relation between the resilient contact-means (CT7) (CT8) (CT9) and its corresponding bus means (buss9) (Buss10) (buss10).
FIG. 15 shows one of the available arrangements for contact means (CT4) (CT5) (CT6), corresponding resilient conductive means (SP4) (SP5) (SP6), and corresponding conductive mean's socket-set receiving-areas (Re4) (Re5) (Re6) of the conductive means (CD4) (CD5) (CD6) to enable a plug to be inserted into the related holes (Slot4) (Slot5) (Slot6). A fastening means holds the rectangular housing (H4) (H5) together, for example by means of a screw, rivet, glue, ultrasonic sealing, chemical compound, etc.
FIG. 16 shows the same track arrangement as FIG. 2 but with different geometric shapes for the outlet-units and socket-sets of the receiving areas.
FIG. 4-1 shows one of the preferred safety curtains (4c) (4c′) (4c′′) between the outlet-units. The safety curtain (4c) is between outlet-units (4b) (4a), with the space expanded to be longer.
