Abstract
An adjustable latching device for tying down a load includes a plurality of elongated rails provided with a slot extending along a length thereof and an elongated and flexible fastening member extendable along a top portion of the load. The device further includes a mechanism for selectively tightening the fastening member so that an operator may adjust a tension of the fastening member from a remote location. An elongated and rigid bar is connected to the tightening mechanism for assisting in maintaining the fastening member at a stable position. Such a fastening member has opposed end portions operably connected to the tightening mechanism and removably attachable to an opposed side of the truck respectively.
Claims12
An adjustable latching device for tying down a load carried on a flatbed truck, said device comprising:
- a plurality of elongated rails securable to selected portions of the truck, said rails being aligned along a substantially horizontal plane and extending parallel to each other;
- an elongated fastening member extendable along a top portion of the load for traversing and laterally spanning across a width of the truck so that the load can be maintained at a substantially stable position during operating conditions;
- and
- means for selectively tightening said fastening member such that tension of said fastening member is adjustable from a remote location;
- wherein said fastening member has opposed end portions operably connected to said tightening means and removably attachable to an opposed side of the truck respectively;
- wherein said tightening means comprises
- a control panel electrically coupled to said tightening means, said control panel including a user interface having a plurality of buttons for toggling said device between selected operating modes,
- an air cylinder having a piston adaptable between retracted and extended positions, said cylinder including a pair of conduits operably connected thereto and to an air supply source for selectively channeling air having a predetermined pressure level to and from said cylinder respectively, said cylinder being slidably attachable to one said rails and movable therealong, said conduits being provided with a pair of quick-disconnect couplings for retrofitting said device to alternate air supply sources,
- a bracket slidably attachable to another said rails and positionable laterally of said one rail adjacent a bed of the truck,
- a spool having opposed end portions connected to said bracket and aligned along the horizontal plane,
- a gear operably attached to one said spool end portion, and
- a sprocket operably attached to another said spool end portion;
- wherein said gear and said sprocket are axially rotatable about said spool along a selected direction and in sync, said fastening member being operably connected to said sprocket and having a tension that can be selectively adjusted.
