ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a support, and more particularly to an adjustable support for supporting work pieces of a machine.
2. Description of the Prior Art
Typically, work pieces are required to be sent and fed into the working machines. The typical work piece supports are provided beside the machines for supporting and/or for feeding the work pieces into the machines. The typical work piece supports comprise a fixed configuration that may not be adjusted according to the machines of various sizes.
The present invention has arisen to mitigate and/or obviate the afore-described disadvantages of the conventional work piece supports.
SUMMARY OF THE INVENTION
The primary objective of the present invention is to provide a work piece adjustable support which may be adjusted to various heights according to the machines of different sizes.
In accordance with one aspect of the invention, there is provided a work piece support comprising a base including a tube, a rod slidably received in the tube and adjustable relative to the tube, a supporting member provided on the rod for supporting work pieces, and means for adjusting the rod relative to the tube.
The base includes a stay pivotally secured to the tube at a pivot shaft and rotatable to engage with the tube at a folded position. The tube includes at least one bar secured thereto, the stay includes a middle portion pivotally secured to the bar at the pivot shaft and includes an upper end engageable with the tube. The tube includes a bracket secured thereto, the bar includes a bent end engaged into the bracket and secured to the tube.
The supporting member includes a frame secured on top of the rod, a roller rotatably secured in the frame at a pivot axle. The rod includes a hub provided on top thereof, the frame includes a sleeve extended downward therefrom and engaged onto the hub for securing the frame to the rod.
The supporting member further includes a casing pivotally secured to the frame at the pivot axle, means for selectively securing the casing to the frame, and at least one ball secured on the casing for selectively supporting the work pieces. The casing includes at least one socket provided therein for receiving the ball.
The adjusting means includes a rack provided in the rod, a pinion rotatably secured to the tube and engaged with the rack of the rod, and means for rotating the pinion to move the rod relative to the tube. The tube includes an oblong hole formed therein and aligned with the rack of the rod, the rotating means includes a housing secured to the tube, a work gear rotatably secured in the housing and engaged with the pinion, and a handle secured to the worm gear for rotating the pinion via the worm 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.
