Arrangement for lifting and lowering objects
Abstract
An arrangement for raising and lowering relative light weight objects from a ground position to a high storage position. A bracket is secured to the high storage position and supports a vertical rotatable shaft, with a pair of horizontal reels and an automatic lock position. A rod is detachably attached to the shaft and extends horizontally downwardly to the ground position. Rotation of the shaft around its central axis causes rotation of the reels. The reels are affixed to two lines which extend generally horizontally from the reels, with the free ends of the lines extending over spaced pulleys and extending downwardly for attachment to the ground level. Rotation of the shaft allows raising and lowering of the object. A spring loaded mechanism associated with the shaft causes automatic locking of the reels in any position, and locks the reels upon raising to the high storage position. The spring loaded locking mechanism is responsive to a slight downward pull on the shaft to an unlocking position, and release of the shaft causes the reels to automatically lock.
Claims
exact text as granted — not AI-modified1 . An arrangement for failsafe vertical raising and lowering an object from a lower ground position to an above ground, elevated position, said arrangement comprising an operating device near the elevated position, said operating device comprising a fixed bracket adapted to be mounted adjacent the elevated position, a short vertical shaft extending a short distance about said elevated position mounted for rotation around its vertical axis in the bracket, a horizontal reel directly affixed to the vertical shaft, a pair of lines having one end affixed to the reel and two free ends extending from the reel first in generally a horizontal direction, a pair of spaced pulley means for changing the free ends of respective lines from generally a horizontal direction to second a generally vertical direction, with said free ends being capable of being extended near the lower ground position for attachment to the object to be raised and lowered, and a long vertical rod means operatively but removably connected to said vertical shaft for direct rotation of said shaft and said reel in either rotary direction, said long vertical rod means being connected to said short vertical shaft for raising or lowering said object, and said long vertical rod being removable from said short vertical shaft to permit free access beneath said operating device and said raised object, said object being raised to an elevated position when said rod means is rotated about its axis in a first direction, and said object being lowered upon rotation of the rod means in
the opposite direction, said long rod means extending downwardly from said short vertical shaft for manual operation by an individual.
2 . The arrangement of claim 1 , wherein said rod means has one of an opening and a hook and the shaft has the other of a hook and opening, and is attachable and detachable from said shaft by engagement of said hook in said opening.
3 . The arrangement of claim 1 , additionally comprising a lock means associated with said shaft for releasably locking said shaft and reel in said elevated position.
4 . The arrangement of claim 3 , wherein said lock means is released upon exertion of a downwardly vertical force on said shaft means.
5 . The arrangement of claim 4 , wherein said lock means is spring biased by a spring toward an upper vertical direction toward a locking position.
6 . The arrangement of claim 5 , wherein a downward pull on said rod means causes release of said spring, and a release of said downward pull causes automatic locking of said lock means.
7 . The arrangement of claim 1 , wherein said vertical shaft has an elongated slot therein, and a horizontal rod passes through said slot and is movable vertically therein.
8 . The arrangement of claim 7 , wherein said bracket comprises downwardly extending tabs engageable with said horizontal rod.
9 . The arrangement of claim 8 , wherein said horizontal rod has rollers near the ends thereof engageable with said tabs.
10 . The arrangement of claim 9 , wherein said tabs are inclined inwardly.
11 . The arrangement of claim 1 , additional damping device means mounted between said vertical shaft and said bracket, said damping device means serving to allow free wheeling of the vertical shaft and reel as the object is being raised, and damped rotation of the vertical shaft and reel as the object is being lowered.
12 . An arrangement for raising and lowering an object from a ground level to a vertical high level, said arrangement comprising a fixed bracket secured near the high level, a pair of horizontal reels mounted for rotation in said bracket, lines extending from said reels for attachment to said device, a tortionally resistant vertical rod means associated with said reels, said rod means capable of rotating said reels when said rod is rotated around its central axis, said rod means being operable from the ground level, and means between said rod means and reels and rod for automatically locking said reels by said rod means.
13 . An arrangement as in claim 1 , wherein said object is a bicycle having handle bars and a seat and one said lines in adapted to be attached to said bicycle near the handle bars of said bicycle and the other of said lines is adapted to be attached to said bicycle near the seat of said bicycle.
14 . The arrangement of claim 1 , additionally comprising a lock means associated with said shaft for releasably locking said shaft and reel in said elevated position, said lock means being released upon exertion of a downwardly vertical force on said shaft means, said lock means being spring biased by a spring toward an upper vertical direction toward a locking position, a downward pull on said rod means causes release of said spring, and a release of said downward pull causes automatic locking of said lock means, said short vertical shaft has an elongated slot therein, and a horizontal rod passes through said slot and is movable vertically therein, said bracket having downwardly extending tabs engageable with said horizontal rod, said horizontal rod having rollers near the ends thereof engageable with said tabs, said tabs being inclined inwardly, and additional damping device means mounted between said vertical shaft and said bracket, said damping device means serving to allow free wheeling of the vertical shaft and reel as the object is being raised, and damped rotation of the vertical shaft and reel as the object is being lowered.
15 . An arrangement as in claim 14 , wherein said object is a bicycle having handle bars and a seat and one said lines is adapted to be attached to said bicycle near the handle bars of said bicycle and the other of said lines is adapted to be attached to said bicycle near the seat of said bicycle.
16 . An arrangement as in claim 14 , wherein said reel has an integral one piece drum with two outer flanges and a center flange thereon with the first line wound on one side of the center flange and the other line being wound on the other side of the center flange.
17 . An arrangement as in claim 1 , wherein said reel has an integral one piece drum with two outer flanges and a center flange thereon with the first line wound on one side of the center flange and the other line being wound on the other side of the center flange.
18 . An arrangement as in claim 1 , wherein said drum for said first line and said drum for other line is integral, said drum having a pair of outer flanges at its ends to contain said lines.
19 . An arrangement as in claim 18 , further comprising a center flange on said drum between said outer flanges.Join the waitlist — get patent alerts
