DESCRIPTION:
BRIEF SUMMARY
This invention relates to a lashing system of the kind used, for example, for securing loads on lorries, pallets or other support or transportation means or for securing together a stack of items. Such a lashing system is herein referred to as being "of the kind specified". Lashing systems of the kind specified generally comprise a plurality of ropes, chains, cables, straps or the like, herein referred to as lashing elements, which are extended over or around part of the load or stack and are secured at their ends, to securing attachments carried by the vehicle, pallet or the like or to the ends of other lashing elements. In such systems, it is generally necessary for the lashing elements to be tightened and secured manually and the difficulty arises that is it frequently not possible for one man to tension the lashing means to the degree necessary for complete security before securing the ends of the lashing means and consequently it is not uncommon for a load on a lorry, for example, to shift or to be shed altogether, creating a substantial hazard.
It is one object of the present invention to provide a tensioning and securing device for a lashing system of the kind specified by which adequate tensioning of lashing elements such as chains, cables, straps etc. can be readily achieved by one man and which is yet adaptable to a variety of applications and situations.
According to the invention there is provided a tensioning and securing device for a lashing system of the kind specified comprising a first and a second member each affording an anchorage for a respective lashing element, said first member being guided for movement relative to said second member through a range of relative positions and means for locking said first member with respect to said second member in a selected one of said positions, said first and second members being adapted for engagement with respective parts of an actuating device operable, when so engaged with said members, to move said members relative to one another through at least part of said range of relative positions.
Embodiments of the invention are described below by way of example with reference to the accompanying drawings in which:
FIGS. 1a and 1b are schematic elevation views showing part of a lashing system embodying the invention before and after tensioning of securing elements,
FIGS. 2a to 2c are schematic elevation views showing one application of the system of FIGS. 1a and 1b,
FIG. 2d is a fragmentary sectional view of a locking means of a device forming part of the system,
FIG. 3 is an elevation view of a variant member forming part of a tensioning and securing device of the system,
FIGS. 4, 4a, 4b and 4c show the application of the system on cargo vessels and the like,
FIGS. 5 and 5a to 5e show an elevation view of a variant system and its application in various ways,
FIG. 6 shows components of a further tensioning and securing device embodying the invention,
FIG. 7 shows a yet further device embodying the invention,
FIGS. 8 to 11 show quick release devices which may be incorporated in the system and
FIGS. 12a and 12b illustrate, in vertical section and in plan respectively, a strap securing device which may be incorporated in the system, and
FIGS. 13-15, 16a, 16b, 16c, 17a, 17b, and 18-21 show further variants and their application.
p Referring to FIGS. 1a and 1b, in one embodiment of the invention, a tensioning and securing device is provided for holding connections and tensioning four lashing elements, such as ropes, chains, cables, straps or the like which, in use radiate from the device. The device shown comprises a generally U-shaped (or inverted U-shaped in FIGS. 1a and 1b) member 10 comprising two parallel legs 12 connected by a base part 14. The device further comprises a cross-bar 16 which extends at right angles to the legs 12 and has spaced apart apertures therethrough through which extend the legs 12. The bar 16 is thus guided for sliding movement relative to the member 10, in the longitudinal direction of the legs 12. The member 16 carries lockin
