Definitions

  • the present invention relates to a device in a pulling member to provide reliable lashing or other holding of cargo or other objects by means of the pulling member - that is actuatable by a tensioning member - and an elastic member straining the same.
  • the main object of the present invention is, among other things, to solve said problems using simple but efficiently working, reliable and cost-effective means in, among other things, lashing straps used for fastening of goods during transportation.
  • Said object is attained by means of a device according to the present invention that essentially is charac- terized in that one part of said elastic member, which is immovably connected with a portion of said pulling member, forms a return part of said pulling member by the opposite, other portion of the elastic member being connected with the opposite free end of said pulling member, and that said pulling member is actuatable by a one-way lock mechanism, whereby slackening of the pulling member is arranged to be counteracted by said elastic member.
  • Figs. 1-6 show a first example of a solution in a strap winch according to the invention, where the different parts are held in tensioning and loosening, respectively, states
  • Figs. 7-10 show a further variant of the first example in a tensioned and disengaged state, respectively.
  • Figs. 11-13 show a second example of a solution of elastic strap tensioning with a two-part return bar
  • Figs. 14-16 show a third example of a solution of elastic strap tensioning.
  • the so-called lashing winch 1 shown in Fig. 1 is equipped with a type of retensioning device 2 that can be arranged in an unloaded I as well as a loaded state II, where Fig. 2 shows said retensioning device 2 in a tightened-up state, and Fig. 5 shows how the lashing strap 3 or another pulling member utilized has been retensioned.
  • a device 1 in a pulling member 3 to provide reliable lashing or other holding of cargo or other objects by means of the pulling member 3 - that is actuatable by a tensioning member 2 - and an elastic member 4 straining the same are shown as examples in the drawings.
  • Said pulling member 3 is actuatable by a one-way lock mechanism 5, whereby slackening 6 of the pulling member 3 is arranged to be counteracted by said elastic member 4.
  • Said one-way lock mechanism 5 is formed of a bar 7 that is compressible and movably displaceable against the pulling member 3 as well as actuatable to be brought into a releasing state of said pulling member 3.
  • a releasing lever 8 is arranged to transfer pivotal motion to a rotatable cam mechanism 9 that is arranged to abut against said lock bar 7, whereby extension of said lever 8 in the direction from the pulling member 3 is arranged to displace the bar 7 in the direction from clamping co-operation with the pulling member 3.
  • said lock bar 7 is displaceably guided in slot-shaped receipt openings 10 in end portions 11 of a formed holder 12 for said mechanism 5.
  • the pulling member 3 may be formed of a strap, a wire or some other suitable strong similar pulling member, and the elastic member 4 is formed of a resilient element, e.g., in the form of a rubber-band ring, the portions 4A, 4B of which facing away from each other are received in surrounding attaching tunnels 13, 14 of the strap 3, and that the rubber- band ring 4, with the free side portions 15, 16 thereof, extends outside the longitudinal side edges of the pulling-mem- ber strap.
  • the one-way lock mechanism 5 is interconnected with a mechanism 17 to provide tightening of the pulling member 3.
  • Said tensioning mechanism 17 is formed of a manually pivota- bly actuatable handle 18 having a return bar 19 or wheel for winding around of the pulling member 3, as well as provided with a releasable ratchet member 20, for manual straining of an additional pulling member 3 or a returned part of said pulling member 3 affectable by the elastic member 4.
  • the tensioning mechanism 17 and the one-way lock mecha- nism 5 may be interconnected, for instance that the two mechanisms 5, 17 are articulately connected with each other via a pivot joint 21.
  • the return bar 19 is suitably formed of pair-wise transverse bar halves 19A, 19B between which the pulling member 3 extends.
  • the strap 3 In the wound state, such as for instance is shown in Fig. 2, the strap 3 is reliably locked by the fact that the strap part presses on the inner strap part around the bar 19.
  • the function of the described device is as follows:
  • the numeral 17 designates a usually occurring type of so-called strap winch, the function of which is not described in detail here, and that the base frame of the mechanism 5 is fitted by the pin bolt 21 in the strap winch 17.
  • the elastic unit (resilient when pulling) , which may be of the rubber-band type, is designated by the numeral 4.
  • the numeral 8 shows the cam arm, the cam-shaped part 9 of which, in the raised position (Fig. 3) displaces the lock bar 7 rearward, thereby releasing the strap 3 from a clamping roller 31.
  • the function is as follows:
  • the cam arm 8 is raised and releases the strap locking 7.
  • the hook 30 (alternatively another anchorage attachment) is then attached to the cargo platform and the strap 3 is drawn over the cargo so that it can be attached on the other side of the cargo using the hook 40.
  • the strap 3 is ten- sioned in the usual way by pumping using the lever 18 of the winch, "the rubber band” 4 being stretched and the holder-on 200 abuts against the base frame.
  • the cam arm 8 is lowered down to the position according to Fig. 4.
  • the mechanism shown in Figs. 7-10 and 11-13, respectively, corresponds in all essentials to the device shown in Figs. 1-6 and described above having contained mechanisms.
  • the two mechanisms 105, 117 are stiffly connected with each other instead of articulately and the elastic rubber band 104 is formed of such a transverse one on each long side of the pulling strap 103.
  • the function is the same as previously.
  • the mechanism 105 comprises a cam and a bar between which the strap 103 is led back from the cam and frapped, see Figs. 9 and 10.
  • This device 301 variant comprises a common frame 360 for a strap 303, 303 1 each having attaching hooks 330, 340 and where the straps run around a lock bar 370, 371 each.
  • the strap end 303 1 A is drawn to a suitable tension.
  • an attached rubber band 304 is then stretched out by means of hand-power, unlike the automatic stretching according to the embodiments described above, into a desired intended tension state where a buckle 380 is angled and displaced in the direction to the right 381 in the drawing in Figs. 14-16.
  • the buckle 380 resembles a hook that is threaded onto the strap 303. Necessary retensioning of the strap/straps 303, 303 1 takes place as previously has been described above.
  • the one-way lock mechanism is formed of a locking part 380 that is movable and lockable angleable along the pulling member 303 and, via the pivotable end thereof facing away from the pulling member, forms the hook 381 that is connected with the elastic member 304.
