  • FIG. 15 is a detail view in perspective illustrating the key for preventing sliding of the buckle lug within the buckle recess.
  • FIG. 16 is a detail view in perspective illustrating the actuator cam for releasing the buckle assembly.
  • the invention involves the provision of a buckle B, a pair of which is illustrated in FIG. 1 as being interposed in an airmans harness generally denoted at H, a female buckle part 1 being connected to a portion of the harness which constitutes a part of an airmans parachute pack and a male buckle part 2 being shown as attached to a portion of the harness H which is secured to the airmans toroso suit or the likwe.
  • Each of the buckle parts 1 and 2 has ears 3 adapted to support a cross-pin 4 whereby the webbing or harness H may be afiixed to the respective buckle parts.
  • the female buckle part 1 comprises a body '5 having a recess or cavity 6 adapted a lug or prong 7 projecting from the body 8 of the male buckle part 2. Slidably supported by the female buckle part body is a latch or slide 9 adapated to engage the lug 7 of the male buckle part 2 to hold the same in the recess 6.
  • actuator means generally denoted at 10 are provided whereby the slide 9 may be manually caused to shift inwardly with respect to the body 5 so as to release the male lug 7 from the recess 6; and, in addition, automatic means generally denoted at 11 are provided for effecting operation of the actuator means so that the buckles may be released, notwithstanding the inability of the airman to personally effect operation of the manual means 10.
  • the female buckle body 5 has a rectangular recess or slide receiving pocket 12 therein adapted to slidably accommodate the slide 9, the slide 9 having a body portion 13 adapted to substantially fill the cavity 12 and a forward angularly disposed face 14 merging with an upper lip portion 15.
  • the face 14 of the slide 9 is adapted to cooperate with a face 16 forming the forward angular surface of the cavity 6 into which the male lug 7 extends when the buckle is assembled.
  • the width of the male lug 7 is such that it will extend laterally into angularly disposed slots 7a formed at opposite extremities of the recess 6 whereby to effect engagement of the lug 7 with the body 5 to prevent hinging of the body parts.
  • a closure plate 21 is adapted to overlie the cavity 12 of the female body section '5 and to be secured in place thereon by suitable fasteners 22 so as to confine the slide 9 within the female body 5.
  • Means are provided for normally biasing the latch slide 9 forwardly toward the face 16 thereof and, in the illustrative embodiment, such means includes a coiled compression spring 23, and end of which is disposed in a seat 24 formed in the rear wall 25 of the female body cavity 12 and acting on the opposing wall of the latch slide 9.
  • the manual actuator means in the illustrative embodiment now being described is seen to comprise a pair of actuator plates respectively designated 30 and 40, these plates being preferably slidably disposed in a recess or cavity 50 in the upper surface of the closure plate 21 so as to be flush therewith.
  • the slide plate 30 has a pair of depending pins 31, 31 extending downwardly through a pair of slots 51, 51 in the closure plate 21.
  • the plate 21 has oppositely facing notches 51a and 51 respectively located at oposite ends of the elongated slots 51, and the pins 31 of the plate 30 are adapted to be disposed in the notches 51a when the plate 30 is in one position, or in the slots 51 when the plate 30 is shifted in a direction to move the pins 31 from the notches 51a.
  • the plate 40 has a pair of depending pins 41, 41 also adapted to extend through the slots 51 and to be engaged either in the notches 5112 or in the slots 51 when shifted in a direction opposite the direction in which plate 30 is shifted to place the pins 31 in the slots 51.
  • the plates 30 and 40 have oppositely facing lug portions 32 and 42 which interenga'ge and overlap a distance greater than either of the plates 30 or 40 is capable of moving but less than the combined motion when both plates 30 and 40 are shifted in directions to move the pins 31 and 41 from the respective notches 51a and 5111, as is apparent from FIGS. 8 and 9.
  • the pins 31 and 41 extend downwardly into a pair of recesses or cavities 60 in the latch or slide 9, and retainer pins 61 extend transversely through the cavities 60 and through openings 62 in the pins 31 and openings 63 in the pins 41.
  • a coiled compression spring 64 is disposed about one of the retainer pins 61 and is adapted to abut with one of the pins 31 depending from the plate 30 so as to bias the plate 30 in a locking direction, that is, to bias the pins 31 into the notches 51a; another coiled compression spring 65 is disposed about the other retainer pins 61 Within one of the cavities 60 and acts in the other direction on one of the pins 41 depending from the plate 40 so as to force the latter in a latching direction, that is, to force the pins 41 into the notches 51b.
  • the pair of cam plates 70 and 80 and the pair of pyrotechnic devices 72 and 82 provide a fully redundant system, either one of which is fully operative to effect release of the buckle.
  • FIGS. 11 through 16 there is illustrated a modified embodiment of the invention in which pyrotechnic devices are employed redundantly but a single lock mechanism is employed requiring the use of only a single cam plate, as will now be described.
  • the manual operating means 110 includes, as in the first described embodiment, a pair of relatively laterally reciprocable plates and having finger pieces 130a and 13% thereon for effecting relative reciprocation of the plates 130 and 140 as well as movement of the plates jointly longitudinally of the buckle assembly, in response to the shifting of a pin 131 from a notch 151a and shifting of a pin 141 from a notch 151b into an elongated slot 151 provided in the closure plate 121.
  • This lip 205 and more particularly the radius portion 207, cooperates with a lip 208 formed on the slide plate 109 and providing a radius at 209.
  • the radius 209 and the radial lip 207 cooperate upon sliding movement of the latch plate 109 into the latched position of FIG. 12. to effectively move the key slightly in the groove 203 as permitted by the lost-motion connection 201, 202 so as to allow interfitting of the lip 208 with the lip 205 of the latch plate 109 and the key 200, respectively.
  • the presence of the key 200 prevents any tendency of the lug 107 to slide along the surface 116 of the recess 106, rendering the entire assembly significantly stronger and capable of resisting axial pulling forces tending to separate the buckle assembly.
