The construction and operation of the first embodiment of the three and five-point buckle assembly


10


will now be described in detail.




Referring to

FIGS. 1A-17

, for assembly and operation, the release button


30


is inserted into the buckle body


20


through one of the buckle body side openings


202


or


203


(direction A shown in FIG.


2


). During insertion, the top and bottom surfaces


200


and


201


, respectively, of buckle body


20


as well as the release button biasing tabs


303


and


304


elastically deform to allow release button


30


to be positioned into buckle body


20


. Once positioned, the release button biasing tabs


303


and


304


bias the top surface


300


of release button


30


through top opening


213


of buckle body


20


. Release button


30


is maintained in a substantially proper lateral alignment with respect to buckle body


20


by means of cutout edges


208


,


209


,


214


and


215


, which bear against the lateral edges of tabs


303


and


304


of release button


30


. Release button


30


is also maintained in the substantially proper lateral and a substantially proper vertical alignment with respect to buckle body


20


by means of indentations


220


and


221


, which substantially prevent top surface


300


of release button


30


from being displaced out of top opening


213


of buckle body


20


. After insertion and positioning of the release button


30


into the buckle body


20


, as shown in

FIGS. 1A-17

, side-tongues


50


(or


50


′) are inserted into channels


216


and


217


of buckle body


20


such that stops


504


fit into recesses


218


and


219


, respectively. The main-tongues


40


are then inserted through the side opening


202


or


203


of buckle body


20


. Each of the main-tongues


40


are guided into one of the openings


202


or


203


of buckle body


20


by sliding engagement between channels


410


and


411


on main-tongues


40


and guide tracks


207


and


206


on buckle body


20


, respectively. As each of the main-tongues


40


are inserted into buckle body


20


, the locking prongs


402


and


403


on arms


400


and


401


, respectively, slide on ramp surfaces


305


or


306


, respectively, of release button


30


. As the main-tongues


40


are further inserted, as shown in

FIG. 17

, the main-tongue ejection tab mating surface


408


on each respective main-tongue


40


is slid between the respective main-tongue ejection tabs


301


or


302


, and the respective ramp surfaces


305


or


306


on release button


30


. As the main-tongues


40


are fully inserted into buckle body


20


, the respective protrusions


204


or


205


on buckle body


20


come into mating engagement with the recess


409


on main-tongues


40


. At this point, the locking prongs


402


and


403


on main-tongues


40


engage the respective main-tongue retaining latches (


311


-


314


) on the release button


30


. Thus the main-tongues


40


are locked into place by means of a mating engagement with release button


30


. Once the main-tongues


40


are locked into place, stop retaining surfaces


412


and


413


on main-tongues


40


bear against stop


504


on the respective side-tongues


50


(or


50


′), and thus prevent side-tongues


50


(or


50


′) from being removed.




In order to release main and side-tongues


40


and


50


(or


50


′), respectively, from the buckle body


20


, the release button


30


is simply depressed against the upwards bias of release button biasing tabs


303


and


304


. Once the release button


30


is depressed, the main-tongue ejection tabs


301


and


302


aid in ejection of main-tongues


40


by providing an outward biasing force in the direction opposite to the insertion direction of main-tongues


40


. Upon release of main-tongues


40


, side-tongues


50


(or


50


′) can be removed from channels


216


and


217


of buckle body


20


. It should be noted that if side-tongues


50


′ are used instead of side-tongues


50


for the three and five-point assembly


10


, the flex fingers


505


on side-tongues


50


′, which are compressed against rib


222


(not shown) of buckle body


20


after assembly, will aid in the ejection of side-tongues


50


′ from channels


216


and


217


of buckle body


20


.




In operation, a conventional strap (not shown) can be attached to strap bar


211


of buckle body


20


. Similarly, a conventional strap (not shown) can be attached to rib


406


of each of the respective main-tongues


40


, and strap-bar


501


of each of the respective side-tongues


50


(or


50


′). In order to adjust the length of the straps (not shown), the buckle body


20


can be translated relative to the strap attached to strap bar


211


. The teeth


212


on the strap bar


211


as well as the edges of the strap bar prevent translation of the buckle body


20


relative to the strap when the strap is placed in tension. The straps attached to the rib


406


of the main-tongues


40


can be adjusted in a similar manner as the straps attached to the buckle body


20


. For the straps attached to the side-tongues


50


(or


50


′) however, the straps can be sewn to the strap-bar


501


at a pre-determined length, or a conventional strap adjuster (not shown) can be used to adjust the length of the strap relative to the side-tongues


50


(or


50


′). After adjustment of the straps, each of the side-tongues


50


(or


50


′) can be inserted into channels


216


and


217


of buckle body


20


, as shown in FIG.


17


. Next, each of the main-tongues


40


can be inserted into buckle body


20


through the respective openings


202


or


203


to engage with the respective main-tongue retaining latches of the release button


30


. The three and five-point buckle assembly


10


has the fully-assembled configuration shown in FIG.


1


A. For releasing the tongues


40


and


50


(or


50


′), as discussed previously, the release button is depressed in a direction substantially opposite to the bias of release button biasing tabs


303


and


304


, and the main-tongues


40


are released from the respective openings


202


or


203


of the buckle body


20


. Removal of main-tongues


40


also allows removal of side-tongues


50


(or


50


′). The strap-bar


211


with teeth


212


and cross-bar


210


on the buckle body


20


, function as a “multi-bar webbing lock” and provide a means for preventing unnecessary movement of the straps attached to the buckle body


20


. Similarly, rib


406


with teeth


407


and rib


405


on each of the main-tongues


40


, function as a “multi-bar webbing lock” and provide a means for preventing unnecessary movement of the straps attached to the main tongues


40


.




It should be noted that the operation of the three and five-point buckle assembly


80


is substantially similar to the operation of assembly


10


, except that the assembly


80


only uses the main-tongues


40


(not the side-tongues


50


or


50


′), constituting the three-point mode as explained above. It will be further appreciated that the preferred three and five-point buckle design of the present invention only places a tensile force on the locking prongs


402


and


403


of the main tongues


40


and the main-tongue retaining latches (


311


-


314


) of the release button


30


, respectively. During insertion and latching, the main-tongues


40


are inserted into buckle body


20


without any deflection of the arms


400


and


401


, locking prongs


402


or


403


of the main tongues


40


, or the main-tongue retaining latches (


311


-


314


) of the release button


30


.




Next, the third embodiment of the three and five-point buckle assembly of the present invention will be described in detail.

70


. Once positioned, the release button biasing tabs


303


and


304


bias the top surface


300


of release button


30


through top opening


713


of buckle body


70


. Release button


30


is maintained in a substantially proper lateral alignment with respect to buckle body


70


by means of cutout edges


708


,


709


,


714


and


715


, which bear against the lateral edges of tabs


303


and


304


of release button


30


. Release button


30


is also maintained in the substantially proper lateral and a substantially proper vertical alignment with respect to buckle body


70


by means of indentations


716


and


717


, which substantially prevent top surface


300


of release button


30


from being displaced out of top opening


713


of buckle body


70


. After insertion and positioning of the release button


30


into the buckle body


70


, as shown in

FIGS. 18 and 26

, main tongues


90


are inserted through the side opening


702


or


703


of buckle body


70


. Each of the main-tongues


90


are guided into one of the openings


702


or


703


of buckle body


70


by sliding engagement between channels


912


and


913


on main-tongues


90


and guide tracks


707


and


706


on buckle body


70


, respectively. As each of the main-tongues


90


are inserted into buckle body


70


, the locking prongs


902


and


903


on arms


900


and


901


, respectively, slide on ramp surfaces


305


or


306


, respectively, of release button


30


. As the main-tongues


90


are further inserted, as shown in

FIG. 26

, the main-tongue ejection tab) mating surface


908


on each respective main-tongue


90


is slid between the respective main-tongue ejection tabs


301


or


302


, and the respective ramp surfaces


305


or


306


on release button


30


. As the main-tongues


90


are fully inserted into buckle body


70


, the respective protrusions


704


or


705


on buckle body


70


come into mating engagement with the recess


909


on main-tongues


90


. At this point, the locking prongs


902


and


903


on main-tongues


90


engage the respective main-tongue retaining latches (


311


-


314


) on the release button


30


. Thus the main-tongues


90


are locked into place by means of a mating engagement with release button


30


.




In order to release main-tongues


90


from the buckle body


70


, the release button


30


is simply depressed against the upwards bias of release button biasing tabs


303


and


304


. Once the release button


30


is depressed, the main-tongue ejection tabs


301


and


302


aid in ejection of main tongues


90


by providing an outward biasing force in the direction opposite to the insertion direction of main-tongues


90


.




In operation, a conventional strap (not shown) can be attached to strap bar


711


of buckle body


70


. Similarly, a conventional strap (not shown) can be attached to rib


906


and transverse strap bar


911


of each of the respective main-tongues


90


. In order to adjust the length of the straps (not shown), the buckle body


70


can be translated relative to the strap attached to strap bar


711


. The teeth


712


on the strap bar


711


as well as the edges of the strap bar prevent translation of the buckle body


70


relative to the strap when the strap is placed in tension. The straps attached to the rib


906


of the main-tongues


90


can be adjusted in a similar manner as the straps attached to the buckle body


70


. For the straps attached to the transverse strap bar


911


however, the straps can be sewn to the strap-bar


911


at a pre-determined length, or a conventional strap adjuster (not shown) can be used to adjust the length of the strap relative to the main-tongues


90


. After adjustment of the straps, each of the main-tongues


90


can be inserted into buckle body


70


through the respective openings


702


or


703


to engage with the respective main-tongue retaining latches of the release button


30


, as shown in FIG.


26


. The three and five-point buckle assembly


60


has the fully-assembled configuration shown in FIG.


18


. For releasing the main-tongues


90


, as discussed previously, the release button is depressed in a direction substantially opposite to the upwards bias of release button biasing tabs


303


and


304


, and the main-tongues


90


are released from the respective openings


702


or


703


of the buckle body


70


. The strap-bar


711


with teeth


712


and cross-bar


710


on the buckle body


70


, function as a “multi-bar webbing lock” and provide a means for preventing unnecessary movement of the straps attached to the buckle body


70


. Similarly, rib


906


with teeth


907


and rib


905


on each of the main-tongues


90


, function as a “multi-bar webbing lock” and provide a means for preventing unnecessary movement of the straps attached to the main-tongues


90


.




It will be appreciated that the preferred three and five-point buckle design of the present invention only places a tensile force on the locking prongs


902


and


903


of the main-tongues


90


and the main-tongue retaining latches (


311


-


314


) of the release button


30


, respectively. Furthermore, during insertion and latching, the main-tongues


90


are inserted into buckle body


70


without any deflection of the arms


900


and


901


, locking prongs


902


or


903


of the main tongues


90


, or the main-tongue retaining latches (


311


-


314


) of the release button


30


.
