Definitions

  • This invention relates to a strap buckle. It is common practice to secure loads, for example, in aircraft holds and on lorries, with webbing straps secured at their one ends to fixed parts of the vehicle structure and coupled at their other ends to a buckle which, in an open position permits a free end of one of the straps to be pulled through the buckle to tighten the straps around the load and in a closed position clamps the straps against further movement to secure the load.
  • the free end of the strap is passed over a first member around a roller and is threaded back over the first member to be accessible outside the buckle.
  • the roller is pivotable about a position adjacent the first member and in the open position of the buckle the line between the roller and the member extends at an oblique angle to the straps and permits the free end to pass easily around the roller and in the closed position of the buckle the line between the roller and the member extends at an acute angle to the straps to increase the friction between the straps, the roller and the member.
  • the buckle is generally held in its closed position by a releasable spring clip.
  • buckles are fabricated from steel sheet; they are heavy and in spite of the use of protective surface finishes they deteriorate rapidly and become increasingly difficult to use. Aluminium alloys have been used for at least parts of such buckles but similar fabrication methods have been employed and aluminium alloy buckles are expensive.
  • a strap buckle for- use with webbing straps comprising a base having a part constituting a first strap engaging member and a cover pivoted to the base adjacent the member and carrying a second strap engaging member extending parallel with the first member, the base being extruded from metal or plastics material in a direction parallel with the axes of the members and subsequently being formed with an aperture' between the location of the first member and an anchorage for one strap end, the aperture being to receive another strap end passed over the first member, around the second member and back over the first member to a position accessible externally of the buckle.
  • the end of the base remote from the first member may be defomable and is either formed as or carries a latch for holding the cover in its closed position.
  • Fig. 1 is a section on the line I-I of Fig. 2 and shows the strap buckle arranged vertically with its cover in the closed position; the open position of the cover being indicated by chain lines, Fig. 2 is a plan view of the buckle with the cover closed,
  • Fig. 3 is an end view of the buckle
  • Fig. 4 is a section on the line of Fig. 5 and is a view similar to Fig. 1 of a modified buckle
  • Fig. 5 is a view similar to Fig. 3 of the modified buckle and
  • Fig. 6 is a view similar to Fig. 3 of the modified buckle.
  • a buckle indicated generally at 1, comprises a base 2 a cover 3 and a release member 4.
  • the base 2 is extruded from a suitable aluminium alloy and has a central flat part 5 formed towards one end constituting a bar 6 with a formation 7 the interior 8 of which is part circular in cross section.
  • the part 5 has an inwardly curved part 9 and an outwardly extending flange 10 separated from the part 5 by a shoulder 11.
  • a rear part 12 of thinner section than the part 5 extends parallel therewith rearwardly of the flange 10 and at its outer end merges with an end wall 13 extending at right angles thereto.
  • the wall 13 Towards its outer end the wall 13 is formed with a rounded beading 14 having an inner surface 15 and spaced from this inner surface a rib 16 extends across the end wall, the space between the rib 16 and the surface 15 constituting a latch as will hereinafter be described. Intermediate its length the end wall is formed with a further rib 17 the upper part of which is inclined at 18. As shown in Fig. 2 the side edges 19 and 20 of the base are tapered from a position adjacent the formation 7 to the end wall 13. As shown particularly in Figs. 1 and 2 the end 6 of the base 2 is separated from the formation 7 by a web 21 or reduced thickness.
  • the emerging extrusion is punched both to cut the outline tapered shape and also to form an aperture 22 in the web, 21.
  • the flange 10 is punched to form an elongated aperture 23 therein.
  • the cover 3 is of -U- shape in section and comprises a pair of tapered side walls 24 and 25 joined by a web 26.
  • the cover is pressed from sheet aluminium alloy.
  • the cover is disposed over the base 2 with the wider ends of the walls 24 and 25 embracing the formation 7 and a tubular rivet 27 incorporating a steel pin 28 is passed through the walls and through the formation 7 to constitute a pivot for the cover.
  • a roller 29 incorporating a steel pin 30 extends between the side walls 24 and 25 of the cover 3.
  • the cover is in its closed position with its end 31 held by the latch at the outer end of the end wall 13 it being understood that to close the cover the end 31 engages the beading 14 to deform the end wall 13 and the rear part 12 to distort these parts.
  • the roller 29 lies adjacent to but spaced from the part 5 in the base 2.
  • the releasing member 4 is also of -U- shape having side walls 32 and 33 joined by a web 34 the latter being formed with a slot 35 to enable the member 4 to be passed over the beading 14 and the rib 16 of the end wall 13 so that the member is located in the position shown in Fig. 1 with its inner end 36 lodged against the shoulder 11 of the base 2 and the inner edge of the slot 35 lodged beneath the rib 16. In this position the end wall 13 is flexed slightly to hold the member 4 firmly in position.
  • the buckle is generally disposed vertically as shown in Fig. 1 and one end 37 of a strap 38 is passed around the end 6 through the aperture 22 and secured by rivets 39.
  • the strap 38 passes around the upper part of a load for example on a lorry and is secured to a fixed part of the vehicle.
  • Another strap 40 secured at its lower end (not shown) to a fixed part of the lorry, passes upwardly through the aperture 23 in the flange 10; through the aperture 22; around the roller 29 and back through the aperture 22 and the aperture 23 to provide a free end 41.
  • the outermost part of the formation 7 extending through the aperture 22 constitutes a first member 42 having a smooth surface around which the strap may readily slide.
  • the threading of the strap 40 through the buckle is carried out with the cover 3 in its open position as shown in chain lines at 3a so that the roller 29 is in the position indicated at 29a.
  • a pin indicated by chain lines at 43, may be passed through apertures (not shown) in the walls 24 and 25 of the cover 3 to engage behind the curved part 9 of the base 2. It will be understood that the cover cannot be released from its latched position without first removing this pin.
  • the friction between the layers of the strap 40 could be increased by disposing the roller 29 nearer the inclined edges of the walls 24 and 25 and providing a recess (not shown) in the part 5 to accommodate the roller in the closed position of the cover 3. Substantially the same result could be achieved by disposing the part
  • Figs. 1 to 3 can be simplified by omitting the release member 4 and extending the beading 14 outwardly (not shown) in a direction parallel with the rear part 12. Hand pressure on this extended part will distort the wall 13 sufficiently to unlatch the end 31 of the cover. It will be understood that with this arrangement the part 5 may merge smoothly into the rear part 12.
  • the curved part 9 may, for convenience also be oppositely disposed.
  • Figs. 4 to 6 The arrangement of Figs. 4 to 6 is not only a simpler construction but it also offers improved performance particularly when the buckle is to be used with rough surfaced webbing straps since the cover 3 will open through180o so that, in its open position, as shown in chain lines in Fig 4, the pin 30 adopts the position 30a. and there is no "wrap 'around" of the formation 7 by the strap 40. This reduces friction and makes it particularly easy to pull the free end 41 of the strap through the buckle.
  • the flanged 10 (Fig. 1) is unnecessary since in the open position there is no torgue tending to rotate the buckle.
  • the part 5 of the base is sufficiently thick that it does not distort when the straps are under tension. Should distortion occur release of the buckle would be difficult since a component of the strap tension would need to be overcome as well as the latching spring force provided by the part 12 and the wall 13.
  • the increased thickness of the part 5 is preferably (as shown in Fig. 4) at least partly on the strap side of the buckle so as to provide clearance for the straps and permit easy sliding.
