Abstract
Abstract A two-tongue buckle assembly including a housing into which first and second tongues may be inserted. A first latch means including an elongated latch bar is biased upwardly by a spring toward the latched position and is movable downwardly by a pushbutton to the unlatched position to coact with the first tongue when inserted thereinto to retain the first tongue in the latched position. A second latch means is included and comprising a support member rotatably connected to the housing and having an arcuate upturned flange on one end for abutting engagement with the first tongue and having a movable latch member supported by a resilient leaf spring at the other end. The resiliently supported latch member is moved by the support member into the path of the second tongue by the first tongue being inserted into the housing and engaging the upturned flange of the support member to rotate the support member so that the latch member movably supported thereon is in the path of the second tongue for latching engagement therewith. The second tongue is therefore retained in the latched position only when the first tongue is inserted into the housing and into the latched position.

Claim 1
Independent Claim
101 words
A buckle assembly comprising; a first tongue, first latch means for receiving an retaining said first tongue in latching engagement therewith, a second tongue, second latch means movable to a latching position in response to the positioning of said first tongue in latching engagement with said first latch means for receiving and retaining said second tongue in latching engagement therewith and movable to a nonlatching position out of the path of said second tongue in response to the removal of said first tongue from said latching engagement with said first latching means for preventing latching engagement thereof with said second tongue.
Claim 2
Dependent Claim
101 words
A buckle assembly comprising; a first tongue, first latch means for receiving an retaining said first tongue in latching engagement therewith, a second tongue, second latch means movable to a latching position in response to the positioning of said first tongue in latching engagement with said first latch means for receiving and retaining said second tongue in latching engagement therewith and movable to a nonlatching position out of the path of said second tongue in response to the removal of said first tongue from said latching engagement with said first latching means for preventing latching engagement thereof with said second tongue.
Claim 3
Dependent Claim
50 words
An assembly as set forth in claim 1 including release means for moving said first latch means to a release position to allow said removal of said first tongue and the movement of said second latch means to said nonlatching position in response to said removal of said first tongue.
Claim 4
Dependent Claim
52 words
An assembly as set forth in claim 1 wherein said second latch means includes a latch member for latching engagement with said second tongue when in said latching position, and movable support means supporting said latch member and responsive to said first tongue for moving said latch member to said latching position.
Claim 5
Dependent Claim
40 words
An assembly as set forth in claim 3 wherein said second latch means further includes first biasing means for moving said support means from said latching position to said nonlatching position in response to said removal of said first tongue.
Claim 6
Dependent Claim
28 words
An assembly as set forth in claim 4 wherein said support means includes a support member and resilient means resiliently supporting said latch member on said support member.
Claim 7
Dependent Claim
49 words
An assembly as set forth in claim 5 wherein said assembly includes a housing having a first opening for receiving said first tongue and a second opening for receiving said second tongue, said support member being rotatably supported by said housing for movement between said latching and nonlatching positions.
Claim 8
Dependent Claim
55 words
An assembly as set forth in claim 6 Wherein said support member has first and second extremities and is rotatably connected to said housing intermediate said extremities, said first extremity of said support member being engageable with said first tongue, said latch member being movably supported by said support member adjacent said second extremity thereof.
Claim 9
Dependent Claim
55 words
An assembly as set forth in claim 7 wherein said housing includes wall means aligned with said first and second openings for guiding said first and second tongues into said housing in paths of movement, said latch member being disposed out of the path of movement of said second tongue when in said nonlatching position.
Claim 10
Dependent Claim
115 words
An assembly as set forth in claim 8 wherein said latch member has an inclined extremity which falls away in the general direction of said second opening, said second tongue includes a head portion followed by at least one void so that said head engages said inclined extremity of said latch member as said second tongue is inserted into said housing to move said latch member relative to said support member to a position out of the path of said second tongue until said void reaches said latch member and said latch member is moved into said void by said resilient means whereby said latch member is in said latching engagement with said second tongue.
Claim 11
Dependent Claim
