A molded plastic buckle adapted to releasably secure extremities of a web-like material includes a receptacle body and an insert body having a tongue portion adapted to be slidably received in the receptacle body. The receptacle body includes a top wall having a through aperture defining a plurality of surrounding side surfaces. At least one of these side surfaces is angled to converge in the direction of slidable insertion of the insert body tongue portion. The insert body tongue portion includes a raised portion receivable within the aperture. This raised portion has a trailing side surface formed at a complementary angle to the angled side surface of the aperture to facilitate locking interengagement between the raised portion and the aperture. A resilient, deflectable bottom wall of the receptacle body deflects in response to slidable insertion of the tongue portion therein, and thereafter urges the tongue portion upwardly to facilitate locking interengagement between the raised portion thereof and the aperture in the receptacle body top wall.
A buckle adapted to releasably secure extremities of a web-like material and comprising a receptacle body having a pair of oppositely facing side walls, an end wall and an end opening opposite said end wall, said side walls, end wall and end opening collectively defining a hollow interior, an insert body including a tongue portion adapted to slidably interfit through said end opening and within said hollow interior, said receptacle body further including a top wall having an aperture therein and a resiliently deflectable member disposed opposite and facing said top wall and extending between said end wall and said end opening, said resiliently deflectable member extending into said hollow interior and said resiliently deflectable member including a ramp surface converging inwardly of said hollow interior from a point adjacent said end opening of the receptacle body and upwardly towards the top wall to a point generally facing an intermediate point in said aperture defined in said top wall, said resiliently deflectable member integrally molded as a portion of said receptacle body and said insert body tongue portion comprising an integrally molded plastic part, said insert body tongue portion further including a raised portion for inter-engagement with said aperture in said top wall, said resiliently deflectable member initially deflecting in response to slidable insertion of said tongue portion into said hollow interior and thereafter resiliently urging said raised portion into at least partial telescopic association and inter-engagement with said aperture in said top wall for discouraging disengagement of said receptacle body from said insert body, said receptacle body and said insert body further being respectively provided with means for receiving said extremities of said web-like material.
A molded plastic buckle adapted to releasably secure extremities of a web-like material and comprising a receptacle body having a hollow interior portion and an end opening communicating with said hollow interior portion, an insert body including a tongue portion adapted to be slidably received in said hollow interior portion through said end opening, said receptacle body further including a top wall portion having a through aperture defining a plurality of surrounding side surfaces, at least one of said side surfaces being formed at a converging angle with respect to the direction said insert body is adapted to be aslidably received, said insert body tongue portion further including at least one raised portion receivable within said aperture, said raised portion defining at least one side surface found at a complementary angle to said at least one side surface having a converging angle defined by said aperture to facilitate locking interengagement between said raised portion and said aperture, and resiliently deflectable means in said hollow interior portion for deflecting in response to slidable insertion of said tongue portion into said hollow interior portion, said resiliently deflected means thereafter urging said tongue portion towards said aperture to facilitate said locking interengagement between said raised portion thereof and said through aperture in said top wall portion of said receptacle body portion.
A buckle adapted to releasable secure extremities of a web-like material and comprising a receptacle body having a pair of oppositely facing side walls, an end wall and an end opening opposite said end wall, said side walls and end wall and end opening collectively defining a hollow interior portion, an insert body including a tongue portion comprising an integrally molded plastic part having a raised part and adapted to slideably interfit through the end opening and within said hollow interior portion, said receptacle body further including an apertured top wall and resiliently deflectable member including a ramp portion converging inwardly at the hollow interior portion from a point adjacent the end opening of the receptacle body and upwardly toward the apertured top wall to a point generally facing an intermediate point in an aperture defined in said apertured top wall, said tongue portion includes a leading ramp surface diverging from a leading edge thereof generally complimentary with said resiliently deflectable member ramp portion and slideably engageable therewith during insertion of the tongue portion into said receptacle body, whereby said ramp portion and said leading ramp surface guide the raised portion of the tongue portion into a position of inter-engagement with said aperture of said apertured top wall, said resiliently deflectable member resiliently urging said raised portion into locking engagement with said aperture.
