Definitions

  • the present invention relates generally to buckles and, more particularly, to so-called three point release buckles having male and female components that automatically engage one with the other for locking and require activation at three distinct points for unlocking.
  • Two-piece buckles that snap together and latch automatically upon adequately inserting a male component into a female component are known and used in a variety of applications. It is known to have a piece of webbing or strap attached to each of the components, and to have one or both buckle components adjustably retained on the strap or webbing. It is also known to have one or both components in fixed locations relative to a strap or web that is sewn or otherwise fixedly secured to the buckle component.
  • Such buckles are known and used for a variety of applications, including outdoor recreational products like backpacks, helmets, life vests and other general equipment; military and police equipment and the like. Two-part buckles are used also on luggage, bags, clothing and the like.
  • the female component defines a pocket and includes openings or windows on the lateral, opposed sides of the pocket.
  • the male component includes arms having outward protrusions slightly wider than the width of the female component at some positions from the entrance to the window. As the male component is inserted into the female component, the arms are deflected inwardly and thereafter are allowed to rebound outwardly when the protrusions align with the windows in the female component. With the protrusion extending slightly outwardly at the window, the male component is secured within the female component. To release the buckle, the exposed protrusions of the arms are squeezed inwardly through the windows of the female component, allowing the male buckle component to be withdrawn from the female buckle component.
  • the strength of the buckle to resist unintended release when pulling force is applied against either component is determined by the nature of the engagement between the male and female component.
  • the resistance to intended release, or stated another way, the difficulty in unlatching the buckle is determined by the resistance to bending of the arms upon squeezing the protrusions inwardly from the window, and the resistance of the engaging surfaces to slide past or otherwise disengage from each other.
  • Buckles of the type described have had success in many applications; however, in some applications and uses for snap together buckles of this type it is desirable that the buckle be somewhat more difficult or complicated to unlatch, so that the buckle does not unlatch unintentionally, and so that individuals other than the user have difficulty in unlatching the buckle.
  • law enforcement officers, military personnel and the like can encounter individuals who are resistant to the orders and commands given them. Physical confrontations can occur. In such a confrontation, the individual may try to unlatch duty belts, equipment or weapons belts worn by the officer or military person. If successful, the individual could use the equipment as a weapon or otherwise entangle or ensnarl the law enforcement officer or military personnel in the loosened equipment.
  • Improvements in a three-point release buckles are desirable so that the buckles are secure in use, resistant to release by persons other than the user, yet easily operated by the user to release when necessary.
  • the present invention provides a three-point release buckle having lateral release points at the side of the buckle and a third release point on the external surface of the buckle positioned so that the buckle can be operated by an individual using three fingers of one hand, or two-hands if so desired.
  • the present invention provides a three- point release buckle with a male component, a female component and first and second releasable latching connections of the male component within the female component operable along opposite sides of the buckle.
  • a third releasable latching connection of the male component within the female component is located between the first and second connections.
  • the third releasable latching connection has a cantilevered spring latch operable along one face of the buckle for releasing a latch along an opposite face of the buckle.
  • the present invention provides a buckle with a male component having lateral arms and a center bar, and a female component defining a pocket for receiving the lateral arms and the center bar. Lateral connections are provided between the lateral arms and the female component with the buckle in a latched condition. A cantilevered spring latch connection is provided between the male component and the female component, including parts of the spring latch on opposite sides of the center bar. [11] In a further aspect of a further form thereof, the present invention provides a buckle with a male component having lateral arms and a center bar having a lip; and a female component defining a pocket for receiving the lateral arms and the center bar.
  • a cantilevered spring latch connection is established between the male component and the female component, including a depressible portion of the female component operably connected to a latch hook engaging the lip with the buckle in a latched condition.
  • An advantage of one aspect of an embodiment of the buckle disclosed herein is providing a buckle that operates smoothly for release by the user, but is difficult to operate by someone other than the user.
  • Another advantage of another aspect of an embodiment of the buckle disclosed herein is providing a buckle that is strong and secure.
  • a further advantage of a further aspect of an embodiment of the buckle disclosed herein is providing a buckle that is resistant to damage from misuse of the buckle.

  • Buckle 10 includes a male component 12 and a female component 14.
  • Male component 12 includes a latch 16 and a web attachment structure 18 including a web bar 20.
  • Female component 14 includes a receiving body or pocket 24 and a web attachment structure 26 including a web bar 28.
  • Latch 16 of male component 12 is inserted into and received by pocket 24 of female component 14 whereby buckle 10 is latched.
  • Male component 12 and female component 14 can be made as individual monolithic structures of plastic formed by injection molding processes, or the like.
  • Straps or webs can be attached to web bars 20 and 28 in known manner so that buckle 10 can be used to secure together opposite ends of a single web or to connect ends of separate webs.
  • one or the other of male component 12 and female component 14, or both male component 12 and female component 14 can be attached directly to an item or article other than a strap or web.
  • web bars 20 and 28 can be used in a manner in which a strap or webbing encircles the bar, with the strap or webbing secured to itself by stitching, rivets or other types of fasteners, or adhesive or other type of attachment, to secure the strap or webbing in a fixed condition on the bar.
  • male component 12 and female component 14 can include multiple bars so that the strap or webbing can engage therewith in a serpentine pattern whereby the male and/or female component is securely positioned relative to the strap or webbing, but may be adjusted along the length of the strap or webbing, in known manner.
  • the arrangement by which one or both of male component 12 and female component 14 are attached to articles, including a strap or webbing is not a limiting factor with respect to the application or use of the present invention.
  • a buckle of the invention can be used in various orientations, vertically, horizontally and at various angles.
  • terms such as top, bottom, upper, lower, side, lateral and the like may be used with reference to the common orientation of the buckle as shown in Figs, 1-4 and 6-9.
  • top, bottom, upper, lower, side, lateral and the like may be used with reference to the common orientation of the buckle as shown in Figs, 1-4 and 6-9.
  • use of such terms describing orientation should not be viewed as limiting either on the use of the invention, or the breadth of the claims to follow.
  • Latch 16 of male component 12 includes first and second lateral latch arms 30, 32 and an intermediate or center bar 34 projecting outwardly from attachment structure 18 of component 12.
  • Center bar 34 is positioned between and spaced from latch arms 30, 32.
  • Arched braces 36, 38 extend to center bar 34 from proximal portions of arms 30, 32, respectively, and connect center bar 34 relative to each arm 30, 32 so that some relative deflection can occur between arms 30, 32 and center bar 34.
  • Arms 30, 32 are mirroring structures of one another and extend into female component 14 when buckle 10 is latched. Proximal ends of arms 30, 32 define thinner flex segments 40, 42 respectively, and distal ends of arms 30, 32 define enlarged or bulbous portions 44, 46 respectively. Bulbous portions 44, 46 project laterally both inwardly and outwardly from axes defined by the non- deflected conditions of flex segments 40, 42, respectively. Upon lateral force exerted against bulbous portions 44, 46 arms 30, 32 deflect or bend along flex segments 40, 42, respectively, proximate attachment structure 18.
  • bulbous portions 44, 46 define catch ledges 48,
  • catch ledges 48, 50 angle outwardly and rearward toward the proximal ends of arms 30, 32.
  • bulbous portions 44, 46 define thinner, guide plates 52, 54 which can be used with cooperating structure within female component 14 for directing relative movement of the male and female components with respect to one another and/or for stiffening distal portions of arms 30, 32.
  • Center bar 34 of the exemplary embodiment shown is a substantially rectangular, box-like structure including side members 60, 62 and a base member 64.
  • Braces 36, 38 are generally connected to base member 64 near the juncture of base member 64 with side members 60, 62.
  • a plate 66 extends between side members 60, 62 and forwardly from base member 64.
  • a distal portion 68 of plate 66 angles downwardly.
  • a lip 70 depends downwardly at the distal end edge of plate 66, from the distal edge of angular distal portion 68.
  • side members 60, 62; base member 64; plate 66 and lip 70 define a generally open box-like structure on the underside of center bar 34.
  • a cutout 72 extends from the free edge of base member 64 substantially intermediate the connections to braces 36 and 38.
  • Receiving body pocket 24 includes upper and lower plates 100, 102 on the top and bottom thereof, and sides 104, 106 between plates 100, 102 along the lateral edges. Sides 104, 106 define inset openings or windows 108, 110, respectively, which are elongated in configuration. Windows 108, 110 are sized and positioned to receive the laterally outwardly projecting segments of bulbous portions 44, 46 respectively when male component 12 is fully inserted into female component 14. Windows 108, 110 are defined partly by latch surfaces 112, 114 for engaging catch ledges 48, 50 of male component 12 when the buckle is latched.
  • Latch surfaces 112, 114 can be angularly oriented complementary to the angles of catch ledges 48, 50 to provide secure engagement inhibiting unintentional unlatching of the buckle.
  • An end panel 116 is provided at the inner end of body pocket 24 in the exemplary embodiment.
  • Upper and lower plates 100, 102 and sides 104, 106 define an entrance opening 120 to the pocket-like structure of receiving body 24, and define the entrance for insertion of the distal ends of latch arms 30, 32 and center bar 34.
  • the inner surfaces of upper and lower plates 100, 102 can define ridges, channels or other configurations for guiding and directing the insertion of male component 12 into female component 14. Accordingly, as shown in Fig. 6, ridges 122, 124 extend inwardly along the inner surface of lower plate 102, and define outwardly flared curved entrance surfaces 126, 128, respectively, for receiving and engaging the lower edges of side members 60, 62 on center bar 34 and directing center bar 34 to a centered position in receiving body 24.
  • a center ridge 130 extends inwardly on the inner surface of lower plate
  • center ridge 130 allows male component 12 to be inserted in only one orientation whereby ridge 130 can pass through cutout 72 as male component 12 reaches full insertion in female component 14. If male component 12 is inverted such that the outer surface of plate 66 slides along ridge 130, the male component can not be fully inserted for latching in that insufficient space is provided between the top edge of ridge 130 and the inner surface of upper plate 100 for male component 12 to be inserted beyond the angular portion of distal portion 68. Proper orientation of male component 12 in female component 14 is needed for proper operation of the third latch structure to be described.
  • a spring latch 132 is provided on the inner end of receiving pocket 24, the end away from entrance opening 120.
  • Spring latch 132 cooperates with center bar 34, and more specifically lip 70 of center bar 34 to provide a third latch area in addition to the latch areas provided by latch arms 30, 32 engaging windows 108, 110.
  • Spring latch 132 is defined by slits 134, 136 in upper plate 100, an end plate 138 contiguous with and extending downwardly from the segment of upper plate 100 between slit 134 and slit 136, and a latch hook 140 at the opposite end of end plate 138.
  • Latch hook 140 projects into the pocket from the lower end of end plate 138, and includes a horizontal segment 142 and a vertical lip 144.
  • Latch hook 140 presents an angular surface 146 exposed to entrance opening 120 whereby, upon insertion of male component 12 into female component 14, lip 70 of male component 12 can ride up and over latch hook 140.
  • the exposed outer surface of the spring latch 132 between slits 134, 136 can be provided with knurls or ridges 148 to facilitate pushing there against when unlatching the buckle.
  • an exemplary embodiment of the invention includes an end edge 150 of lower plate 102 providing a spring latch stop positioned so to confront and engage the outer edge of latch hook 140 when the latch hook is depressed adequately to release center bar 34.
  • This allows spring latch 132 to be depressed sufficiently to disengage latch hook 140 from lip 70 without over deflecting the spring latch, whereby the spring latch could break, or lip 70 could be deflected downward a sufficient amount that it would encounter lower plate 102 and be difficult to remove.
  • Spring latch 132 in the exemplary embodiment shown further includes lateral wings 152, 154 projecting from opposite sides of end plate 138.
  • Lateral wings 152, 154 extend outwardly beyond the outer edges of slits 134, 136 to prevent excessive movement of spring latch 132 in an upward direction. Lateral wings 152, 154 can confront and engage the inside surface of upper plate 100 if spring latch 132 is moved upward excessively. End edge 150 and wings 152, 154 guard against accidental breakage through misuse of buckle 10
  • buckle 10 In using buckle 10, the buckle is latched by inserting male component 12 into female component 14. Specifically, latch 16 is aligned with receiving body pocket 24, and distal ends of latch arms 30, 32 are moved into entrance opening 120. The angular distal ends of latch arms 30, 32, which are longer than center bar 34, begin first orientation of male component 12 relative to female component 14. As center bar 34 enters entrance opening 120, entrance surfaces 126, 128 and ridges 122, 124 more accurately align male component 12 with female component 14. If male component 12 is positioned inverted from the desired orientation, as angular distal portion 68 of plate 66 fully enters the pocket further advancement is inhibited. Final advancement of male component 12 into female component 14 can occur only if center ridge 130 aligns with cutout 72.
  • the inside width of receiving body pocket 24 is of slightly narrower dimension than the non-deflected width of latch arms 30, 32; at least upstream of windows 108, 110. Accordingly, the latch arms are deflected inwardly until bulbous portions 44, 46 progress into receiving body pocket windows 108, 110. When aligned with the windows, bulbous portions 44, 46 rebound outwardly such that catch ledges 48, 50 thereof engage latch surfaces 112, 114, respectively. The angular orientations of catch ledges 48, 50 and latch surfaces 112, 114 inhibit unintended unlatching if the male and female components are pulled in opposite directions.
  • male component 12 is removed from female component 14 by simultaneously disconnecting the first and second lateral latches established by catch ledges 48, 50 engaging latch surfaces 112, 114; and also disengaging latch hook 140 from lip 70.
  • a user of the buckle simultaneously squeezes the sides of the buckle to deflect latch arms 30, 32 inwardly to disengage catch ledges 48, 50 from latch surfaces 112, 114, while at the same time using a finger or fingers to apply pressure against the outer surface of upper plate 100 in the area between slits 134, 136, specifically against knurls or ridges 148. Pressure applied on the outer surface of female component 14 in the area between slits 134, 136 unlatches spring latch 132 from center bar 34.
  • Spring latch 132 is thereby moved downwardly, including downward movement of latch hook 140 until vertical lip 144 is moved beyond engagement with lip 70. Disengaging the three latch connections simultaneously allows male component 12 to be pulled from female component 14. If only one or two of the latch connections are operated, the buckle will not disengage. All three must be operated simultaneously to disengage the latch.
