Description

(54) IMPROVEMENTS IN OR RELATING TO LOAD SECUREMENT (71) We, SPANSET INTER A.G., a Joint Stock Company organised under the laws of Switzerland, of 25, St. Jakobs-Strasse, CH--4002 Basle 2, Switzerland, do hereby declare the invention for which we pray that a Patent may be granted to us, and the method by which it is to be performed to be particularly described in and by the following statement: This invention relates to load securement and, more particularly, to a flexible element for securing loads, for example on a road vehicle.
According to the present invention there is provided a flexible element for securing loads, comprising a strap, a chain and a connector fixedly attached to one end of the strap and detachably connected to the chain by means of a slot into which one chain link is inserted whereby lengthwise movement of the chain is prevented by the angularly offset links at each side of said one link.
Preferably, the strap is made of webbing.
The invention will now be further described by way of example only with reference to the accompanying drawings, in which: Fig. 1 is an elevation of one embodiment of connector in accordance with the invention; and Fig. 2 is a sectional view showing the connector in use.
A connector comprises a body 1 in which are formed an elongate opening 2 and a keyhole opening 3 having a circular portion 3a and a slot portion 3b directed away from and at right angles to the opening 2. At the closed end of the slot portion 3b is an integral bridge portion 4 which provides a projection 5, 6 to each side of the body 1.
In use, one end of a length of webbing 7 is fed through the opening 2, and returned to be stitched to itself. The webbing 7 may also be provided with a tensioning device (not shown). A chain 8 is threaded through the circular portion 3a of the keyhole opening 3 and pulled by hand to tension the flexible element constituted by the webbing 7, chain 8 and connector 1. The chain 8 is then moved sideways to insert a link 9 of the chain into the slot portion 3b of the keyhole opening 3. As the chain 8 is released tension exerted by the load in the direction of the arrow 10 causes the link 9 to slide in the slot portion 3b until arrested by the next adjacent link 11 which, in accordance with conventional chain construction, is angularly offset relative to the inserted link 9 and therefore cannot pass through the slot portion 3b.The chain 8 is now locked against further lengthwise movement in the direction of arrow 10. Tensioning of the flexible element may now be effected by means of the webbing tensioning device.
The lower limb of the link 9 is supported on the bridge portion 4 and the projection 6 engages in the adjacent link 12 to permit a substantially linear descent of the tensioned part of the chain from the link 9 thereby avoiding undesirable stresses.
Release of the flexible element is effected by displacing the inserted chain link 9 from the slot portion 3b into the circular portion 3a of the keyhole opening 3 thereby permitting lengthwise movement of the chain 8.
In the illustrated embodiment of connector 1 access to the slot portion 3b is from the circular portion 3a of the keyhole opening 3. In an alternative design, this slot portion is accessible from outside the body of the connector thereby avoiding the need to thread the chain through the connector for manual tensioning. Such a modified connector may thus have the appearance of a conventional grab hook or a chain shortener. Whatever form is taken by the connector the bridge portion providing the lateral projections may be omitted or may provide a projection to only one side of the connector body.
WHAT WE CLAIM IS:- 1. A flexible element for securing loads, comprising a strap, a chain and a connector

    The invention will now be further described by way of example only with reference to the accompanying drawings, in which: Fig. 1 is an elevation of one embodiment of connector in accordance with the invention; and Fig. 2 is a sectional view showing the connector in use.
    A connector comprises a body 1 in which are formed an elongate opening 2 and a keyhole opening 3 having a circular portion 3a and a slot portion 3b directed away from and at right angles to the opening 2. At the closed end of the slot portion 3b is an integral bridge portion 4 which provides a projection 5, 6 to each side of the body 1.
    In use, one end of a length of webbing 7 is fed through the opening 2, and returned to be stitched to itself. The webbing 7 may also be provided with a tensioning device (not shown). A chain 8 is threaded through the circular portion 3a of the keyhole opening 3 and pulled by hand to tension the flexible element constituted by the webbing 7, chain 8 and connector 1. The chain
    8 is then moved sideways to insert a link
    9 of the chain into the slot portion 3b of the keyhole opening 3. As the chain 8 is released tension exerted by the load in the direction of the arrow 10 causes the link 9 to slide in the slot portion 3b until arrested by the next adjacent link 11 which, in accordance with conventional chain construction, is angularly offset relative to the inserted link 9 and therefore cannot pass through the slot portion 3b.The chain 8 is now locked against further lengthwise movement in the direction of arrow 10. Tensioning of the flexible element may now be effected by means of the webbing tensioning device.
    The lower limb of the link 9 is supported on the bridge portion 4 and the projection 6 engages in the adjacent link 12 to permit a substantially linear descent of the tensioned part of the chain from the link 9 thereby avoiding undesirable stresses.
    Release of the flexible element is effected by displacing the inserted chain link 9 from the slot portion 3b into the circular portion 3a of the keyhole opening 3 thereby permitting lengthwise movement of the chain 8.
    In the illustrated embodiment of connector 1 access to the slot portion 3b is from the circular portion 3a of the keyhole opening 3. In an alternative design, this slot portion is accessible from outside the body of the connector thereby avoiding the need to thread the chain through the connector for manual tensioning. Such a modified connector may thus have the appearance of a conventional grab hook or a chain shortener. Whatever form is taken by the connector the bridge portion providing the lateral projections may be omitted or may provide a projection to only one side of the connector body.
    WHAT WE CLAIM IS:- 1. A flexible element for securing loads, comprising a strap, a chain and a connector fixedly attached to one end of the strap and detachably connected to the chain by means of a slot into which one chain link is inserted whereby lengthwise movement of the chain is prevented by the angularly offset links at each side of said one link.
  2. 2. A flexible element as claimed in claim 1, wherein the connector is a link having an elongate opening through which the strap is looped and a keyhole opening having a circular portion through which the chain can pass freely and a slot portion directed away from the elongate opening and adapted to receive a link of the chain thereby locking the chain in position.
  3. 3. A flexible element as claimed in claim 1 wherein the connector is a grab hook or a chain shortener.
  4. 4. A flexible element as claimed in any one of the preceding claims including a bridge portion for supporting the inserted chain link.
  5. 5. A flexible element as claimed in claim 4, wherein the bridge portion provides at least one lateral projection for engaging in the chain link adjacent to and on the tension side of the inserted link.
  6. 6. A flexible element substantially as herein described with reference to and as illustrated in the accompanying drawings.
