Definitions

  • This invention relates to a buckle such as may be used to secure the end of a flexible strap to some item, or to secure two ends of flexible straps together.
  • the invention may be applied to straps used for any securing purpose but is particularly, but not exclusively, concerned with securing straps which may be used to hold items of cargo on a vehicle or other means of transport, or on a pallet for use in transporting the item.
  • the present invention provides a locking buckle for securing one end of a flexible strap, comprising a body member, a handle member pivotally mounted on the body member for movement between a released position and a secured position, a cross-bar fixedly mounted on the handle member at a point eccentric to the point of pivoting of the handle member on the body member and a locking member movably mounted on the handle member to form a nip between it and the cross-bar, the arrangement being such that with the handle member in the released position an end of a flexible strap may be looped around the cross-bar with a single thickness of strap passing through said nip and with a double thickness lying against the locking member and so that on movement of the handle member to the secured position the strap is tensioned by the eccentric movement of the cross-bar and the tension in the double thickness of the strap urges the locking member to close said nip and grip the single thickness of the strap against the locking bar.
  • said body member is formed with an abutment over which a latch plate attached to a second end of the strap may be hooked.
  • said handle member is formed with a cam surface arranged to hold the latch plate on said abutment when the handle is in said secured position while allowing removal of the latch plate from the abutment when the handle member is in said released position.
  • said cross-bar is of generally rectangular cross-section with rounded edges, said nip lying along a longer face of the cross-section.
  • said locking member is in the form of a roller.
  • roller is in the form of a tube loosely positioned over a pivot shaft so as to be movably mounted on the handle member.
  • Figure 1 shows in schematic side cross-section a buckle arranged to secure the ends 10 and 11 of a flexible strap 12, to one another.
  • the buckle comprises a body member 13 comprising a base and two side plates 13A, 13B on which a handle member 14 is pivotally mounted by means of a pivot shaft 15.
  • the handle member is in the form of two side plates, one only of which is shown in the drawings, with the pivot shaft 15 extending between them and on either side of the handle member to be supported in the side plates 13A, 13B of the body member 13.
  • a cross-bar 16 which is of generally rectangular cross-section with rounded edges also extends between the side plates 14A, 14B of the handle member 14, as does a locking member 17 in the form of a tube loosely positioned on the pivot shaft 15 so as to be movably mounted on the handle member.
  • a nip indicated generally at 18 is formed between the locking member 17 and the cross-bar 16.
  • the end 10 of the flexible strap In order to secure the end 10 of the flexible strap to the body 13, and thus any item to which the body 13 may be secured, the end 10 is looped round the cross-bar 16 with a single thickness passing through the nip 18 and with a double thickness lying against the locking member 17.
  • the eccentric movement of the cross-bar 16 about the pivot shaft 15 tensions the strap end 10 around the roller 17 to tighten the strap, while when the handle member 14 reaches the secured position the tension in the strap end 10 then reacts on the tubular roller 17 to urge it towards the cross-bar 16 closing the nip 18 to grip the strap firmly.
  • the handle member 14 is provided with a catch pin 20 which is engageable by a hooked portion 21 of a movable catch member 22 pivotally mounted by means of a pin 23 on the body 13, to releasably secure the handle member 14 in the secured position as indicated in Figure 2.
  • the catch member 22 may be pivoted away from the catch pin 20 to release the handle member 14, when the tension in the strap end 10 will cause the handle member 14 to pivot towards the released position.
  • a resilient washer 30 is provided on the pin 23 on each side of the catch member 22.
  • the washers 30 each provide a resilient abutment which is engaged by the face 31 on the respective side plate 14A, 14B of the handle 14 when it is in the second position, and thus hold the handle with the catch pin 20 firmly held in or "clinched in” the hooked portion 21 of the catch member 22.
  • the buckle is arranged to secure the strap end 10 to the strap end 11.
  • the body 13 is provided with an abutment 24 over which a suitable aperture 25 in a latch plate 26 attached to the end 11 of the strap, may be hooked as shown particularly in Figure 2.
  • the handle member 14 is provided with a cam surface 27 on each side plate, which is arranged to engage the latch plate 26 and hold it over the abutment 24, as seen in Figure 2 when the handle member 14 is in the closed position, whereas when the handle member 14 is in the released position as shown in Figure 1 the latch plate 26 may be moved in and out of the body member 13 to hook over or be released from the abutment 24.
  • the strap 12 may optionally be attached as for instance at points 28 and 29 to a vehicle body or a pallet to assist in the attachment of an item of cargo to the body by the strap 12.
  • the invention provides a buckle which allows for the engagement and separation of flexible securing straps without removal of the straps from their attachment to a body, for the free running of a loose end of the strap through the buckle to remove the slack and for the secure locking of the strap either to a body or to the other end of the strap.
