BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to light set and more particularly, to an emergency light set.

2. Description of the Related Art

Conventional rod-like hand tools (such as screwdriver, socket wrench, and etc.) may be equipped with an illuminator. These hand tools simply work as a specific tool. Further, regular hand tools with illuminator are commonly bulky and heavy, not convenient to work. These hand tools use a battery to provide the necessary working voltage to the illuminator. The user must frequently replace the battery before battery low. Therefore, conventional hand tools with illuminator are not suitable for use as an emergency light set.

SUMMARY OF THE INVENTION

The present invention has been accomplished under the circumstances in view. It is the main object of the present invention to provide an emergency light set, which uses a rechargeable battery to provide the necessary working voltage to the lamp. It is another object of the present invention to provide an emergency light set, which uses a hand-operated power generator to generate electricity for the lamp when battery failed, and a transmission gear set for driving the hand-operated power generator to generate electricity. According to still another object of the present invention to provide an emergency light set, which is equipped with a detachable hand tool that can be used for turning the transmission gear set to drive the hand-operated power generator to generate electricity with less effort.

To achieve these and other objects of the present invention, the emergency light set comprises a bottom cover shell; a top cover shell covered on the bottom cover shell, the top cover shell having a top open chamber and a plughole in a front side of the top open chamber; a lamp mounted in a front side of the bottom cover shell; a mini power generator mounted inside the bottom cover shell and electrically connected to the lamp and adapted to generate electricity for the lamp; a transmission gear set mounted inside the bottom cover shell and adapted to drive the mini power generator to generate electricity, the transmission gear set having an input shaft suspending in the plughole of the top cover shell; and a rechargeable battery mounted inside the bottom cover shell and electrically connected to the lamp; wherein a tool handle is detachably mounted in the top open chamber of the top cover shell and connectable to the input shaft of the transmission gear set for operation by the user to rotate the input shaft and to further drive the mini power generator to generate electricity, the tool handle comprising an adapter for holding a tool tip, the adapter being insertable into the plughole of the top cove shell and connectable to the input shaft of the transmission gear set.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Referring toFIGS. 1–5, an emergency light set in accordance with the present invention is shown comprised of a top cover shell10, a bottom cover shell20, a transmission gear set41, a mini power generator43, and a tool handle30.

The top cover shell10comprises a front lampshade13, a lamp14provided behind the front lampshade13, a top open chamber11, a vertical plughole12disposed in the top open chamber11near the front side, and a battery-charging power jack16provided at the rear side.

The bottom cover shell20comprises a receiving chamber21, a rechargeable battery22mounted in the receiving chamber21and electrically between the lamp14and the battery-charging power jack16, and an on/off switch23disposed on the outside and electrically connected in series between the lamp14and the rechargeable battery22.

The transmission gear set41and the mini power generator43are fixedly mounted on a mounting plate40, which is then installed in the receiving chamber21of the bottom cover shell20above the rechargeable battery22. After installation of the transmission gear set41and the mini power generator43with the mounting plate40in the bottom cover shell20, the top cover shell10is closed on the bottom cover shell20. The transmission gear set41is coupled to the shaft of the mini power generator43, having an input shaft42suspended in the plughole12of the top cover shell10for rotation by the user to drive the mini power generator43, thereby causing the mini power generator43to generate electricity and to provide generated electricity to the lamp14.

The tool handle30comprises a hollow tool handle body31, which defines a receiving chamber32for keeping a set of tool bits35, an adapter34pivoted to the front side of the tool handle body31for holding and turning one of the set of tool bits35, and a cap33, which closes the receiving chamber32. The adapter34is inserted into the plughole12in the top cover shell10and coupled to the input shaft42of the transmission gear set41, and the tool handle body31is set in the top open chamber11of the top cover shell10. The user can turn the tool handle body31out of the top open chamber11and driven by hand to rotate the input shaft42of the transmission gear set41and to further drive the mini power generator43to generate electricity. The user can also remove the tool handle30from the top cover shell10and attach one tool bit35to the adapter34to form a hand tool for a particular work.

Referring toFIG. 2andFIG. 1again, when the tool handle30is received in the top open chamber11of the top cover shell10, the adapter34is maintained inserted into the plughole12in the top cover shell10and coupled to the input shaft42of the transmission gear set41, therefore, the tool handle30is kept firmly in the top cover shell10. When the user switched on the on/off switch23, the lamp14is turned on to give off light. Further, the user can connect city power supply to the battery-charging power jack16to charge the rechargeable battery22.

Referring toFIGS. 3 and 4andFIG. 1again, when the rechargeable battery22fails due to power low or is damaged, the user can lift the tool handle body31and drive the tool handle body31with the hand to rotate the input shaft42of the transmission gear set41and to further drive the mini power generator43to generate electricity, providing the necessary working voltage to the lamp14.

Referring toFIG. 5, the user can also remove the tool handle30from the top cover shell10and attach one tool bit35to the adapter34to form a hand tool for a particular work.

Referring toFIG. 1again, the top cover shell10further comprises a tool chamber15holding a tool rack17, which comprises a plurality of compartments18for keeping small tool elements.

A prototype of emergency light set has been constructed with the features ofFIGS. 1–5. The emergency light set functions smoothly to provide all the features discussed earlier.
