ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a tool, and more particularly to a tool having a rotatable driving head and having a light device attached to the rotatable driving head.
2. Description of the Prior Art
U.S. Pat. No. 5,875,692 to the present applicant discloses a typical ratchet tool. U.S. Pat. No. 5,713,656 to the present applicant discloses a typical tool having a light device. However, when the typical tools include a rotatable driving head, the light device may not be engaged in the driving head due to the rotation engagement of the driving head to the handle.
The present invention has arisen to mitigate and/or obviate the afore-described disadvantages of the conventional tools.
SUMMARY OF THE INVENTION
The primary objective of the present invention is to provide a tool including a light device attached to a rotatable driving head for lighting purposes.
In accordance with one aspect of the invention, there is provided a tool comprising a handle including a chamber for receiving at least one battery, a housing pivotally secured to the handle at a pivot shaft for supporting at least one light bulb, and means for electrically coupling the battery to the light bulb and to energize the light bulb even when the housing is rotated relative to the handle.
The light bulb and the battery each includes a center electrode and a case electrode, the electrically coupling means includes a first conductor and a second conductor coupled to the center electrode and the case electrode of the light bulb, and a third conductor and a four conductor coupled to the center electrode and the case electrode of the battery and electrically coupled to the first and the second conductors respectively. The first and the second conductors each includes a ring rotatably provided around the shaft and electrically coupled to the first and the second conductors for electrically coupling the battery to the light bulb and to energize the light bulb when the housing is rotated relative to the handle. A fifth and a sixth conductors each includes a ring-shape rotatably provided around the shaft and engaged with the rings of the first and the second conductors respectively, and each includes a terminal electrically coupled to the first and the second conductors.
The handle includes a channel and a passage formed therein and communicating with each other, the terminals of the fifth and the sixth conductors are extended through the passage and received in the channel of the handle and electrically coupled to the first and the second conductors. The housing includes a pair of annular recesses formed therein for receiving the rings of the first and the second conductors respectively.
A ratchet mechanism is provided in the housing, and a driving stem is coupled to the ratchet mechanism and to be controlled by the ratchet mechanism. The driving stem is rotatably secured to the housing, the ratchet mechanism includes a first and a second ratchet gears slidably engaged on the driving stem and rotated in concert with the driving stem, a third and a fourth ratchet gears rotatably and slidably engaged on the driving stem and slidably engaged in the housing and rotated in concert with the housing, and means for biasing the third and the fourth ratchet gears to engage with the first and the second ratchet gears respectively, and means for selectively disengaging the third and the fourth ratchet gears from the first and the second ratchet gears to control a driving direction of the driving stem.
A cartridge is secured in the housing and has at least one channel formed therein, a barrel is rotatably engaged on the driving stem and rotatably received in the cartridge, the third and the fourth ratchet gears each includes a projection slidably engaged in the channel of the cartridge for slidable in the cartridge and for rotating in concert with the cartridge.
The selectively disengaging means includes a ferrule secured to the barrel and having at least one extension engaged with the projection of the third ratchet gear for disengaging the third ratchet gear from the first ratchet gear, and includes at least one actuating surface provided in the barrel for engaging with the projection of the fourth ratchet gear to disengage the fourth ratchet gear from the second ratchet gear.
Further objectives and advantages of the present invention will become apparent from a careful reading of a detailed description provided hereinbelow, with appropriate reference to accompanying drawings.
