Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
223 words
Apparatus for the lashing down of articles to the cargobearing bed of a means of transport comprising at least one tightening strap and associated rotatable twisttight drum, said strap extending above and at least partly laterally along the articles to be lashed down, one end of said tightening strap being attached to the means of transport and the other end being attached to its associated twist-tight drum for tightening retraction and loosening extension of said strap with respect to said articles, said tightening strap twisttight drum being mounted for winding and unwinding rotation on the means of transport adjacent said other end of said tightening strap, and at least one lifting strap and associated rotatable twist-tight drum, one end of said strap being attached to said tightening strap at a point intermediate its ends and the other end being attached to its associated twist-tight drum for lifting retraction and lowering extension of said strap, said lifting strap twist-tight drum being mounted for winding and unwinding rotation on the means of transport, the rotation of said twist-tight drums being controllable so that the tightening retraction of said tightening strap is accompanied by a corresponding lowering extension of said lifting strap to lash down the articles and loosening extension of said lifting strap by a corresponding lifting of said tightening strap away from the articles.
Claim 2
Dependent Claim
223 words
Apparatus for the lashing down of articles to the cargobearing bed of a means of transport comprising at least one tightening strap and associated rotatable twisttight drum, said strap extending above and at least partly laterally along the articles to be lashed down, one end of said tightening strap being attached to the means of transport and the other end being attached to its associated twist-tight drum for tightening retraction and loosening extension of said strap with respect to said articles, said tightening strap twisttight drum being mounted for winding and unwinding rotation on the means of transport adjacent said other end of said tightening strap, and at least one lifting strap and associated rotatable twist-tight drum, one end of said strap being attached to said tightening strap at a point intermediate its ends and the other end being attached to its associated twist-tight drum for lifting retraction and lowering extension of said strap, said lifting strap twist-tight drum being mounted for winding and unwinding rotation on the means of transport, the rotation of said twist-tight drums being controllable so that the tightening retraction of said tightening strap is accompanied by a corresponding lowering extension of said lifting strap to lash down the articles and loosening extension of said lifting strap by a corresponding lifting of said tightening strap away from the articles.
Claim 3
Dependent Claim
43 words
The apparatus according to claim 1 in which said tightening strap in its loosened position extends generally horizontally above and vertically on one side of the articles at a distance therefrom together with a supporting structure abutting the articles on their other side.
Claim 4
Dependent Claim
66 words
The apparatus according to claim 1 together with a pair of independently drivable shafts, one of said shafts having mounted thereon and spaced along the shaft at regular intervals the twist-tight drums associated with all of said tightening straps, and the other of said shafts having mounted thereon and spaced along the shaft at regular intervals the twist-tight drums associated with all of said lifting straps.
Claim 5
Dependent Claim
78 words
Apparatus according to claim 3 in which a clutching means is provided between each drum associated with a tightening strap and the shaft upon which it is mounted whereby after each tightening strap has been retracted and reached a taut condition preventing further turning of its associated drum, its associated drum is locked against unwinding and slackening of said tightening strap and further turning in the tightening direction of the shaft carrying the tightening strap drums is permitted.
Claim 6
Dependent Claim
43 words
ApparatuS according to claim 4 in which the shaft driving the tightening strap drums is provided with means holding it under a controllable tightening torque to maintain tension in all tightening straps even in the event of a shift of the lashed-down articles.
Claim 7
Dependent Claim
19 words
Apparatus according to claim 1 having a plurality of neighboring tightening straps interconnected by a network of cross straps.
Claim 8
Dependent Claim
17 words
Apparatus according to claim 1 in which at least part of said tightening straps comprises elastic material.
