    Description

    BRIEF DESCRIPTION OF THE DRAWINGS

    [0016] FIG. 1 shows the device according to the invention. The device is an integral or one-piece toggle bar made of a suitable metal or synthetic polymeric material.

    [0017] FIG. 2 shows the device according to the invention assembled into a generator breaker box where the generator is in an “on” mode.

    [0018] FIG. 3 shows the device according to the invention assembled into a generator breaker box where the generator is in an “off” mode.

    DETAILED DESCRIPTION OF THE INVENTION

    [0019] The invention is best described in reference to the drawings. FIG. 1 shows the toggle bar (1) of the instant invention. The toggle bar (1) is one-piece of suitable metal or synthetic polymer. The toggle bar (1) is dimensioned to fit between a pair of 30 amp double breakers provided inside the conventional home generator breaker box. According to the invention the generator breaker box is electrically connected to the home breaker box. As best seen in FIG. 2 and FIG. 3, first 30 ampere breaker bar (2) disconnects, or turns off the external power source, i.e. the utility electric transmission, while the other 30 ampere breaker bar (3) turns on the emergency generator. It must be understood that the external utility transmission of power is fed through the home breaker box to the generator breaker box. By arranging the two breaker boxes in this way, the external utility power transmission can remain electrically connected to every load in the home when the emergency generator is not functioning. Only those loads electrically connected to the emergency generator power source through the generator breaker box can be independently powered by the generator.

    [0020] The following disclosures of FIG. 2 and FIG. 3 refer to the home breaker box. First toggle hole (4) is dimensioned to register with first breaker holes (5) and second toggle hole (6) is dimensioned to register with and second breaker holes (7). As can be readily seen in FIG. 2 and FIG. 3, first breaker holes (5) are located on the outer terminal end of a pair of 15 amp breakers that toggle together, providing a 30 ampere current. First toggle bolt (8) extends through first toggle hole (4) and axially links first toggle hole (4) to first breaker holes (5). Simultaneously second toggle bolt (9) extends through second toggle hole (6) and axially links second breaker holes (7). Bolts (8) and (9) are sized in diameter to provide a sliding fit with first breaker holes (5) and second breaker holes (7). Bolts (8) and (9) are also be sized to provide a sliding fit through first toggle hole (4) and second toggle hole (6). Alternatively, bolts (8) and (9) can be sized to provide an interference fit through first toggle hole (4) and second toggle hole (6). Bolts (8) and (9) can be any form of clasp, pin or shaft, threaded or unthreaded, or partially threaded, so long as bolts (8) and (9) can freely rotate within first breaker holes (5) and second breaker holes (7). Any suitable fastener or terminal structure such as a nut or screw head can be provided on the ends of bolts (8) and (9) to securely maintain bolts (8) and (9) in register with first breaker holes (5) and toggle hole (4), and second breaker holes (7) with toggle hole (6).

    [0021] Of course, first toggle hole (4) and second toggle hole (6) must be positioned so that adequate clearance is provided between the bottom of the toggle (1) and the top of the space between the pair of 15 ampere breakers. This is to ensure that the toggle (1) allows the breakers to completely open or close. Equally important is the length dimension between first toggle hole (4) and second toggle holes (6), to ensure that first toggle hole (4) axially aligns with first breaker holes (5) at the same time that second toggle hole (5) axially aligns with second toggle holes (6). In this manner, when toggle (1) is secured between the first breakers and the second breakers, the homeowner merely grasps the toggle (1) and simultaneously operates both the first breaker and second breaker. Thus, when the emergency generator is turned to the “on” position, the electrical connection to the outside, utility line is simultaneously turned to the “off” position. The homeowner cannot accidently connect the emergency generator to the utility transmission line, which is especially dangerous should a utility repairman be working on the utility line.

    [0022] FIG. 2 shows toggle (1) installed between a first breaker (2), through which external electrical power conducts, and second breaker (3), through which the emergency generator provides power to the home. First toggle bolt (8) extends through first toggle hole (4) and axially registers with first breaker holes (5). As seen in FIG. 2, the first breaker (2) is in the “on” position. Second toggle bolt (9) extends through second toggle hole (6), and axially registers with second breaker holes (7). As seen, second breaker (3) is in the “off” position. Because of the length of toggle (1) and the linkage to both first breaker (2) and second breaker (3), it is impossible to have the emergency generator in the “on” position, providing power to the home, and simultaneously have the second breaker (3) in the “on” position, whereby the generator will load the outside utility line with a dangerous current. It must be understood that those loads which are powered by the generator are electrically connected through the generator breaker box at all times, both through the generator toggle (3) and through the external power toggle (2). Because toggle (1) prevents generator toggle (3) and external power transmission toggle (2) from both being in the “on” position simultaneously, the loads connected to the generator cannot be simultaneously connected to the external power source. By way of example, it is desirable to have emergency power generators electrically connected at a minimum to a refrigerator and selected lights. In the case of rural homes a well pump is always connected. The refrigerator, selected lights and pump are connected through the generator panel at all times, both through external toggle (2) and generator toggle (3). Should the external power transmission fail, the user simply operates toggle (1) thereby disconnecting the refrigerator, lights, and pump from the utility transmission through external toggle (2). Because the refrigerator, lights, and pump are also connected through the generator toggle (3), when external toggle (2) is turned to the “off” position, power to the refrigerator, lights, and pump is switched from the external source to the generator simultaneously. At no times can the refrigerator, selected lights, and pump be connected to both the external power transmission and the generator. Of course, those loads that the user does not wish to connect to the generator, such as non-essential lighting, are electrically connected only to the external power transmission through the home panel.

    [0023] FIG. 3 shows the generator breaker box in the mode for the emergency generator to power selected loads with the external power disconnected to those selected loads. Toggle (1) is installed between a first breaker (2), through which external electrical power conducts, and second breaker (3), through which the emergency generator provides power to the home. First toggle bolt (8) extends through first toggle hole (4) and axially registers with first breaker holes (5). As seen in FIG. 2, the first breaker (2) is in the “off” position. Second toggle bolt (9) extends through second toggle hole (6), and axially registers with second breaker holes (7). As seen, second breaker (3) is in the “on” position. Because of the length of toggle (1) and the linkage to both first breaker (2) and second breaker (3), it is impossible to have the emergency generator in the “on” position, providing power to the home, and simultaneously have the second breaker (3) in the “on” position, whereby the generator will load the outside utility line with a dangerous current.

    [0024] To use the toggle (1) according to the instant invention, the toggle (1) is placed between breaker (2) and breaker (3). Toggle bolts (8) and (9) link toggle (1) to breakers (2) and (3). It is most important that when installing toggle (1), breaker (2) is in the “on” position, and breaker “3” is in the off position. Alternatively, when installing toggle (1), breaker (2) can be in the “off” position and breaker (3) is in the “on” position. Toggle (1) when installed in this manner guarantees that breaker (2) and breaker (3) cannot simultaneously be in the “on” position, thereby creating an extremely dangerous condition.

    [0025] When toggle (1) is properly installed, the power sources for the home can be readily managed in a safe manner. For example, should the homeowner lose power for any reason, he simply flips the emergency generator breaker (2) into the “on” position. Because the positive linkage toggle (1) mechanically links emergency generator breaker (3) and external power breaker (2), all electrical connection to the utility line is safely disconnected. The homeowner cannot unknowingly place a voltage on the external power line and endanger a utility worker. The danger when a homeowner's generator is electrically connected to the external power transmission line cannot be overemphasized. When this occurs, the step-down transformer operates in reverse and steps-up the homeowner's electric generation to extremely dangerous voltages. The instant invention completely eliminates the possibility that the homeowner's generator transmits current over the utility line.

    [0026] When the homeowner desires to return to the external utility power source, he merely turns the breaker (3) to the “on” position. This simultaneously disconnects or turns off the emergency generator.

    [0027] The instant toggle of the invention could equally be used to prevent one power source from connecting to two loads. For example, if one power source provides current to either a primary pump or a back-up pump, the toggle could ensure that if the primary pump is turned off, the emergency pump simultaneously turns on. Numerous other examples are possible. It is expressly understood that the toggle according to the invention is not to be limited to emergency generators, but is useful wherever two breakers cannot both be in the same mode at the same time.
