Abstract
A cargo container is provided with a door opening having means for engaging and disengaging the top and/or bottom of the door on vertical movement thereof. A hollow rail extends across the top and/or bottom of the door opening and has elongated slots therein provided with slot-enlargements for receiving a foot or feet of a locking member movable along the bottom and/or top of the door. The locking member includes a reduced portion movable through the slot and an enlarged portion having a transverse dimension greater than the width of the slot. Suitable means, preferably rack and pinion means, are provided for shifting the locking members along the door to locking position after movement through the slot-enlargements into the interior of the rail.
Claims17
A container having a generally rectangular opening, a door movably bodily into and out of said opening, said container having at the top of the opening upper retainer means for releasably engaging the top edge of said door and a bottom rail extending across the opening at the bottom thereof, said rail having inwardly directed spaced flanges leaving an upwardly open elongated slot therebetween, the spacing between said flanges being increased for a limited distance to define a lock-receiving slot-enlargement, said door having means for engaging said upper retainer means to support the upper edge of said door against forward displacement except when the entire door is moved substantially vertically, the bottom edge of said door having a downwardly depending lock member shaped to move through said slot-enlargement but dimensioned to be engageable with the underside of said flanges adjacent said slot when said lock member is moved longitudinally of said rail out of registration with said slot-enlargement, and means for moving said lock member along the bottom edge of said door after insertion downwardly through said slot-enlargement to retain said door against vertical movement and hence against removal from said container opening.
A container having a generally rectangular opening, a door movable bodily into and out of said opening, said container having at the top of the opening upper retainer means for releasably engaging the top edge of said door and a bottom rail extending across the opening at the bottom thereof, said rail having inwardly directed spaced flanges leaving an upwardly open elongated slot therebetween, the spacing between said flanges being increased for a limited distance to define a lock-receiving slot-enlargement, said door having means for engaging said upper retainer means to support the upper edge of said door against forward displacement except when the entire door is moved substantially vertically, the bottom edge of said door comprising an elongated bottom frame bar having an upwardly open channel defined by a bottom wall, an upwardly extending flange, and a rear wall, the bottom wall of said channel having an elongated opening therethrough, a slide in said channel slidable on the bottom wall thereof, a retainer bar in said channel overlying said slide and secured to said flange and rear wall, a lock member secured to the underside of said slide and movable therewith along the bottom edge of said door, said lock member having a narrow portion movable in said slot and an enlarged lower portion movable through said slot-enlargement and having a width greater than the width of said slot.
A container having a generally rectangular opening, a door movable bodily into and out of said opening, said container having at the top of the opening upper retainer means for releasably engaging the top edge of said door and a bottom rail extending across the opening at the bottom thereof, said rail having inwardly directed spaced flanges leaving an upwardly open elongated slot therebetween, the spacing between said flanges being increased for a limited distance to define a lock-receiving slot-enlargement, said door having means for engaging said upper retainer means to support the upper edge of said door against forward displacement except when the entire door is moved substantially vertically, the bottom edge of said door comprising an elongated bottom frame having an upwardly open channel defined by a bottom wall, an upwardly extending flange, and a rear wall, the bottom wall of said channel having an elongated opening therethrough, a slide in said channel, a rack connected to said slide, a pinion in said channel, a shaft fixed to said pinion, a pivot mount for said shaft fixed in said channel, and an operating handle secured to said shaft.
