Abstract

Abstract A loading dock for facilitating the transport of articles from piers to haulaway vehicles or the like includes a pair of spaced apart ramps rotatably secured to a base at one end thereof. Coacting means disposed on the lateral exterior side of the dock enables the ramps to be locked in any position between the horizontal and vertical. The present loading dock is particularly adapted for loading automotive vehicles onto trailers therefor.

Claims Analysis

Total Claims: 14
Claim 1
Independent Claim 121 words
A loading dock comprising: a. a base structure, b. a pair of spaced apart ramps pivotally mounted on the base structure for rotation between a substantially horizontal position and a substantially vertical position, c. locking means associated with each of the ramps for positioning the ramps, the locking means being interconnected such that the locking means are simultaneously moveable to position the ramps anywhere betweeN the horizontal and vertical position, each of the locking means comprising: 1 a tubular member pivotally connected to the base structure and having a plurality of apertures disposed therealong, 2 an extended collar pivotally connected to the ramp, 3 a locking pin insertable through the apertures, and wherein the tubular member telescopes within the extended collar.
Claim 2
Dependent Claim 121 words
A loading dock comprising: a. a base structure, b. a pair of spaced apart ramps pivotally mounted on the base structure for rotation between a substantially horizontal position and a substantially vertical position, c. locking means associated with each of the ramps for positioning the ramps, the locking means being interconnected such that the locking means are simultaneously moveable to position the ramps anywhere betweeN the horizontal and vertical position, each of the locking means comprising: 1 a tubular member pivotally connected to the base structure and having a plurality of apertures disposed therealong, 2 an extended collar pivotally connected to the ramp, 3 a locking pin insertable through the apertures, and wherein the tubular member telescopes within the extended collar.
Claim 3
Dependent Claim 47 words
