Abstract
In a releasable locking device, which is useful at a beam-to-column connection in a storage rack, a housing having a lateral wall with two parallel slots has an end wall at an outer end and is open at the inner end, a locking pin having an internal portion movable within and along the lateral wall is movable between a retracted position and an extended position, toward which the locking pin is biased, and an outer sleeve is movable outside and along the lateral wall of the housing and is connected to the locking pin via a connecting pin extending through the locking pin, through the parallel slots, at each end to the outer sleeve. The outer sleeve has an external flange to facilitate pulling of the outer sleeve to move the locking pin toward the retracted position.
Claims6
A releasable locking device comprising
- (a) a housing, which housing has a lateral wall, an outer end, and an inner end, which housing has an end wall closing the outer end, and which housing is open at the inner end, the lateral wall having an elongate slot,
- (b) a locking pin, which locking pin has a internal portion movable inside and along the lateral wall of the housing, which locking pin has a locking portion, which locking pin is movable between a retracted position wherein the internal portion of the locking pin is spaced from the end wall of the housing by a comparatively lesser distance and an extended position wherein the locking portion of the locking pin extends from the inner end of the housing and wherein the internal portion of the locking pin is spaced from the end wall of the housing by a comparatively greater distance, and which locking pin is biased toward the extended position, and
- (c) an outer sleeve, which outer sleeve is movable outside and along the lateral wall of the housing and which outer sleeve is connected to the locking pin via a connecting pin extending from the locking pin, through the elongate slot, the outer sleeve being connected to an end of the connecting pin.
