Definitions

  • the invention relates to quick release buckles for backpacks and the like.
  • Web straps on light weight backpacks, rucksacks and hiking packs typically use "side-action" buckles to allow shoulder, compression and/or large pocket straps to be parted.
  • This side-action buckle design has significant limitations when used in this capacity.
  • the release tabs are recessed onto the sides of the buckle so they can be difficult to find and release when hurried or when wearing winter gloves. Both release tabs must be squeezed simultaneously toward each other to part the buckle. The hand force required to push the halves together and lock them cannot be increased/decreased without a proportional impact on the hand force required to unlock them.
  • the exposed locking tabs of the male-half (tongue) of the buckle can be easily broken off and the female-half (body) can be crushed if stepped on.
  • the present invention embodies an inexpensive, two-piece buckle that can be conveniently opened even while hurried or wearing winter gloves.
  • the buckle can be opened with the natural, intuitive upward pulling action.
  • the forces required to lock and release the buckle are independently controlled.
  • the buckle is durable even when the two interlocking halves are separated.
  • the invention in one embodiment, comprises a two-piece lanyard release buckle including a keeper and a secure part.
  • the keeper has a floor which includes a front portion and a rear portion.
  • a cover is spaced apart from the floor, the opposed surfaces of the floor and cover defining a slot therebetween.
  • a keeper surface is formed on one of the opposed surfaces of either of the floor or the cover.
  • the floor and cover are flexibly secured one to the other.
  • a lanyard is secured to the cover.
  • the secure part is configured to be received in the slot.
  • the secure part has a front portion and a rear portion.
  • the secure part is characterized by at least one locking finger extending from the rear portion to the front portion whereby as the secure part is received in the keeper, the secure part travels along a first axis, the locking finger engages the keeper surface and locks the secure part to the keeper.
  • the lanyard is pulled upwardly.
  • the keeper surface travels along a second axis distinct from the first axis to release the keeper surface from the locking finger thereby unlocking the buckle.
  • a strap adjustment locking system is joined to either the rear portion of the keeper and/or secure part, preferably to the rear portion of the keeper.
  • the system comprises side walls extending from the rear portion, which side walls terminate in an access wall.
  • the access wall is characterized by a slot.
  • Top and bottom plates each characterized by openings in registration with one another, are joined to the side wall.
  • the access wall, side walls and top and bottom plates define a chamber.
  • a clamping bar is received in the system.
  • a strap passes through the slot around the clamping bar and back through the slot.
  • the clamping bar with the attached strap is adapted to reciprocate in the chamber between a locked position where the clamping bar and strap are frictionally engaged to the system and an adjustment position where the clamping bar is spaced apart from the access wall whereby the strap may be adjusted.
  • the openings in the plates facilitate the threading of the strap through the system and the movement of the strap when the strap is being adjusted.
  • positive ejection of the secure part from the keeper is effected.
  • a spring tab is formed in the cover of the keeper.
  • a guide rail on the secure part flexes the spring tab resulting in the secure part being locked to the keeper part under tension.
  • the cover of the keeper is lifted, releasing the locking finger, the spring tab ejects the secure part.
  • the locking system is joined to the rear portion of the keeper and the cover is flexible.
  • a buckle 10 embodying the invention comprises a keeper 20 and a secure part 60.
  • the buckle 10 includes a strap adjustment locking system 100.
  • the keeper 20 includes a floor 22, opposed walls 24a and 24b, each wall 24a and 24b is characterized by a slot 26a and 26b respectively.
  • a back wall 28 extends from the floor 22.
  • a cover 30 is flexibly joined to the back wall 28 and extends over and is spaced apart from the floor 22 to form a socket 32.
  • the cover 30 has edges 34a and 34b spaced apart from the walls 24a and 24b.
  • the cover 30 has a leading edge 36 characterized by a slot 40.
  • a lanyard 46, Fig. 4 passes through the slot 40.
  • the underside of the cover 30 has mirror image keeper ribs 38a and 38b, the keeper ribs 38 having guide surfaces 42a and 42b and keeper surfaces 44a and 44b.
  • the secure part 60 comprises a floor 62 having a leading edge 64 and a rear wall 66 and side walls 68a and 68b. Extending from the rear wall 66 is a housing 70 characterized by a slot 72. A strap 74 passes through the slot 72 as shown. Extending forwardly from the rear wall 66 and toward leading edge 62 is a guide rail 76 and two flexible locking fingers 78a and 78b. The fingers 78a and 78b terminate in catch tabs 80a and 80b respectively.
  • the opposed locking fingers 78 on the secure part 60 are flexed outwardly toward the sides of the secure part 60 by the guide surfaces 42 of the ribs 38 on the keeper 20.
  • the guide rail 76 on the secure part 60 slides between the ribs 38 in the keeper 20 to align the keeper 20 and secure part 60.
  • the keeper 20 and the secure part 60 lock together when the fingers 78 snap past the keeper surfaces 44 and the catch tabs 80 engage or lock to the keeper surfaces 44.
  • the buckle 10 is released when the lanyard 46 attached to the cover 30 of the keeper 20 is pulled upwardly and flexes the keeper surfaces 44 out of alignment with the catch tabs 80. Because the locking fingers 78 flex on the horizontal plane of the buckle 10 and the cover 30 flexes vertically (90 degrees offset), the force required to insert and lock the buckle is completely independent of the force required to release the buckle.
  • the insertion/retention force can be adjusted by the stiffening or softening the flexing action of the fingers 78 while release action can be adjusted by stiffening or softening the flexing section of the cover 30. This important attribute allows the locking/load-bearing and release actions to be independently adjusted to the demands of a particular application. For example, it is possible to design the buckle to produce a stiff locking, high load-bearing capability while maintaining a light release action, or vice versa.
  • the cover 30 can be made of a rigid material and spring loaded to provide the desired flexibility.
  • the fingers 78 can also be stiff and spring loaded if desired.
  • a single finger 78 and keeper surface 44 can be used rather than two. Also, the position of the fingers and keeper surface can be reversed.
  • the locking fingers are protected.
  • the guide rail 76 and raised sides 68 restrain the locking fingers 78 from movement beyond their breaking point.
  • the keeper 20 cannot be crushed easily because pressure on the flexing cover 30 section will bend it slightly downward until the ribs 38 contact the floor 22.
  • the cover 30 is characterized by a spring tab 90, which extends into the socket 32.
  • the end of the guide rail 76 engages and flexes (loads) the spring tab 90 such that both the spring tab 90 and guide rail 76 are engaged under tension.
  • the spring tab flexes driving the guide rail 76 to facilitate the disengagement of the secure part 60 from the keeper 20.
  • a strap adjustment/locking system 100 extending rearwardly from the wall 28 is a strap adjustment/locking system 100.
  • the system 100 comprises walls 102a and 102b joined at one end to the wall 28 of the keeper 20 and at the other end to an access wall 104 having a slot 106 formed therein.
  • Upper and lower access openings 108a and 108b in registration with one another are formed in the system 100.
  • the walls 28, 102a and 102b and 104 define a chamber 110.
  • a moveable clamping bar 112 is slidably received in the chamber 110 and can pass freely through the slot 106.
  • the bar 112 comprises a chamfered section 114 and a tongue 116.
  • a strap 118 is threaded through the slot 106 and around the bar 112 as shown.
  • the strap 118 when the strap 118 is to be adjusted, the strap 118 is grasped and moved rearwardly causing the bar 112 to move rearwardly. This, in essence, releases the strap within the slot 106 and the strap 118 may be manipulated such as by thumb and forefinger to adjust the strap.
  • the cover 30 is characterized by a spring tab 90, which extends into the socket 32.
  • the end of the guide rail 76 engages and flexes (loads) the spring tab 90 such that both the spring tab 90 and guide rail 76 are engaged under tension (Fig. 12).
  • the spring tab 90 flexes driving the guide rail 76 to facilitate the disengagement of the secure part 60 from the keeper 20.
  • the means 100 for adjustably retaining the strap could alternatively or in addition be incorporated in the secure part 60.
  • buckle is described as being a lanyard release buckle, it could also be used in other similar applications.
