Abstract: A cam type buckle pinches a strap between a transverse blade of a pivotable tongue of the buckle and a laterally and transversely extending surface of a base of the buckle to pinch the strap in the longitudinal direction (the direction the strap extends through the buckle from end-to-end) and so that the frictional force exerted by the strap on the blade where the strap is pinched by the blade against the surface tends to rotate the tongue into a closed position.

Abstract: A buckle comprising a rectangular frame including a pair of lateral frame members and a pair of first and second longitudinal frame members interconnected therewith and a substantially rectangular belt stopper pivotally mounted on the lateral frame members with a belt interposed between the belt stopper and the longitudinal frame members. As the belt stopper turns in one direction, one side of the belt stopper brings the belt into pressing engagement with the inner edge of the first longitudinal frame member.

Abstract: A harness assembly for a backpack includes a pair of straps, a pair of right angle cinch rings, and a buckle. The right angle cinch rings allow the straps to be tightened on the chest of the wearer by pulling on the strap ends which are around the wearer's waist and fastening the buckle. The right angle cinch rings maintain the tightness of the straps on the wearer's chest when the buckle is loosened, preventing the pack from sliding down the wearer's back.

The engaging member in the buckle-engaged position is substantially completely within the peripheral bounds of the recess to prevent inadvertent disengagement of the engaging member from the receiving member. The assembly further includes a flexible tongue protruding from the engaging member to allow the engaging member to be pulled out of the recess to disengage the buckle.

Abstract: A suspender loop buckle which has a latch for adjustment of the size of the loop and a clamp for secure attachment of the suspender strap to the buckle. The latch and clamp mechanisms both consist of a pivoting plate attached to the frame of the buckle and operate under similar principles. In the open position a plate is perpendicular to the frame and the strap can move freely between the plate and the frame. In the closed position a plate is parallel to frame and the strap is secured by pressure against a serrated flange. Whereas the latch can be easily opened by pressure on the edge of the latch in the direction of the frame, the clamp cannot be opened in this manner. The strap can be quickly and easily secured to the buckle without the use of special tools. The strap can also be easily disengaged from the buckle.

The tethering devices are secured to each side of the child safety seat at a generally 45 degree angle to the base of the child safety seat.

Abstract: The invention relates to a waistband fastener, especially for trousers, skirts or the like, comprising a latch rail (1) fixed to a waistband portion (A) and bearing a plurality of sawtooth-like teeth (3), on which latch rail a slider (2) connected to the other waistband portion (B) is guided in an adjustable and latchable manner. To enable a simple and advantageous handling and operation of the fastener, a latch finger (12) can be selectively brought into and out of engagement with the teeth of the latch rail by means of a transverse shifting of the slider away from and toward the latch rail. In the first case, the latch finger simply slides over the teeth, by virtue of riding up on their sloping faces, when the slider is moved in one direction (arrow y) along the latch rail. In the other case, the latch finger is shifted out of the tooth gaps (4) and clear of the teeth to permit movement of the slider in the opposite direction.

Abstract: A buckle fitting that can tension with leverage, lengths of belt or webbing. The buckle will lock the belt at any point along its length until freed by a quick release mechanism. The buckle consists of two u-sections pivotably connected at one end to allow a hinge action of the longer upper section about the lower section. A spring loaded cam with a limited movement, rocks away from the surface of the lower section to allow belt to move forward and moves closer to the surface of the lower section to prevent belt moving backwards. A cylindrical roller locates across the lower section between the cam and the hinged join. A slot in the upper section allows belt to pass through when the upper section is closed over the lower section. When the upper section is levered in an arc about the lower section the relative aspect of the slot alters enabling belt to be caught and pulled further through the cam in the lower section. Repeating this action further advances the belt through the buckle.

The tongue-shaped presser further has on its bottom side a pair of resilient pieces.

Abstract: A quickly and easily adjustable buckle enables an equestrian to rapidly and precisely adjust the height of his or her stirrups relative to the saddle with less distraction than the equipment disclosed in the prior art. This provides a great advantage in many equestrian sports, in which it is desirable to rapidly transition from a "high iron" position in which the stirrups are raised, as during a race, to a "low iron" position in which the stirrups are lowered immediately after the horse has galloped. The rapidity, ease and precision with which the present invention enables these adjustments to be made greatly enhances the safety of both rider and horse during this critical phase.

Abstract: Clasps for conductive grounding straps. Clasps according to the present invention allow the strap material to exit the clasp with its conductive side facing the wearer rather than being exposed. The resulting closure decreases the possibility of accidental contact of conductive sections of the strap with high voltage or other dangerous electrical potential that can result in injury or death to the wearer. Because the material exits the clasp with its conductive side not exposed, the free position of the material extending beyond the clasp need not be cut for safety reasons. The strap may thus be adjusted to accomodate various wrist sizes and be used by various wearers.

The belt retraction locking means includes a latitudinally disposed ridge on the base member and a first cam latitudinally disposed on and pivotal about the axis of the pivotal top member, the belt being disposed therebetween, which define a belt locking position when the top member is pivoted to align the ridge and first cam, the belt being pinchingly arrested therebetween.

Abstract: Clamping means for a strap, adapted to be located between a strap storage location and a strap utilization location, comprises reaction member pivotally mounted on a base member for angular movement about a first axis, a guide member pivotally mounted on a support member fast with the reaction member for angular movement about a second axis positioned between the reaction member and the first pivot axis. Resilient means retains the guide member and the reaction member in respective rest positions in which the strap is freely movable between the guide member and reaction member until the tension applied to the strap exceeds a predetermined level. When the tension in the strap exceeds said predetermined level, angular movement of the guide member causes corresponding angular movement of the reaction member, thereby wrapping the strap round both the reaction member and the guide member so that one layer of the strap is clamped against the reaction member by another layer of the strap.

Abstract: The pivoted jaws (2,3) of a buckle for a strap (4) are held together by fastening means (22,23) which define a first closed position of the buckle, but which are such as to allow closer approach of the jaws when they squeeze the strap between them. A moment is exerted, if the strap is pulled, between an edge (9) over which it is turned and which is offset from the pivot (10) and this has the effect of causing closer approach of the jaws and thus an increasedly positive hold. Teeth (20) on one of the jaws are of a saw-tooth profile to permit movement of the strap in one direction even when the buckle is closed. Both jaws may be respective one-piece integral plastics mouldings.
