Abstract
A one-piece plastics moulding includes a pair of flaps 12a, 12b connected by a hinge 14. Both of the flaps 12a, 12b are slotted so that, when they are folded about the hinge 14 to their closed position, a pair of parallel bars 22, 24 is presented for use in adjustably securing a strap 20. Both of the flaps 12a, 12b have spikes 54, 56 for use in trapping a web-like workpiece 48. Any parts of the buckle 10 which touch, such as free ends of the spikes 56 located in complementary apertures 52, can be fixed together by ultrasonic welding, heat sealing or adhesive.
Claims4
In combination with a workpiece, and a wrapable strap member, said strap member having a free-end portion, an improved buckle, said improved buckle being readily fixedly securable to said workpiece, said strap member being adjustably securable to said improved buckle, said improved buckle comprising:
- a one-piece plastic member, said one-piece member including a first flap and a second flap integral through a resilient hinge with said first flap;
- said first and second flaps including means for clinching said workpiece engaged therebetween, said workpiece-clinching means being in distal relation to said hinge, for readily fixedly securing said buckle to said workpiece;
- said first and second flaps including bar means having a first bar and a second bar for adjustably securing said strap member to said buckle, said bar means being proximate to said hinge in relation to said workpiece-clinching means, said strap member extending in one direction from said buckle and said free-end portion being wrapable around said first bar and then directable back in said one direction between said second bar and the remainder of said strap member for causing said free-end portion of said strap member engaging said second bar to be secured to said buckle and for pulling said flaps around said hinge and against said workpiece engaged therebetween, said buckle when fixedly secured to said workpiece being rotatable about the axis of said first bar for disengaging said strap member from said second bar thereby permitting adjustment of said strap member secured to said buckle.
