Child resistant buckle

A buckle, comprising:

• a female portion with lateral supports near a first end;
• a male portion with lateral resiliently flexible tangs each having an inner region opposing each other;
• said lateral supports can receive said tangs when said male portion is inserted into said female portion;
• said tangs being urged towards each other upon being received by said lateral supports;
• said tangs having a length sufficient to extend beyond said lateral supports when said male portion is completely inserted into said female portion, whereby said tangs are no longer urged towards each other and abut an inner end of said lateral supports to resist withdrawal of said male portion from said female portion;
• and
• an enlarged protrusion on an end of said at least one tang sufficient to increase an urging force applied to said tangs and a displacement distance to be traversed by said at least one tang to free said at least one tang from said female portion to permit said male portion to be withdrawn from said female portion.

A child resistant buckle, comprising:

• a female part with an opening on a first end having opposed walls extending a distance away from said opening, at least one of said walls having an end surface opposed to said opening;
• a male part having a base and laterally resilient flexible tangs coupled to said base and extending a length away from said base;
• said opposed walls being cooperative with said tangs when said male part is inserted into said female part to urge said tangs towards each other;
• said length of said tangs being greater than said distance of said walls such that said tangs extend beyond said walls when said male part is sufficiently inserted into said female part, such that at least one of said tangs engages said end surface of said at least one wall to resist withdrawal of said male part from said female part;
• and
• an extended protrusion connected to said at least one tang sufficient to increase a displacement distance traversed by said at least one tang to disengage said tang from said end surface to permit withdrawal of said male part from said female part, such that a level of difficulty of unbuckling the buckle is increased.

• a male part having a base and laterally resilient flexible tangs coupled to said base and extending a length away from said base;
• said opposed walls being cooperative with said tangs when said male part is inserted into said female part to urge said tangs towards each other;
• said length of said tangs being greater than said distance of said walls such that said tangs extend beyond said walls when said male part is sufficiently inserted into said female part, such that at least one of said tangs engages said end surface of at least one of said walls to resist withdrawal of said male part from said female part;
• and
• a web structure between said base and said at least one tang to increase an urging resistance of said tangs when urged towards each other, such that a force sufficient to disengage said at least one tang from said end surface to permit withdrawal of said male part from said female part is increased, such that a level of difficulty of unbuckling the buckle is increased.

A buckle, comprising:

• a female part with an opening on a first end having opposed walls extending a distance away from said opening, at least one of said walls having an end surface opposed to said opening;
• a male part having a base arid laterally resilient flexible tangs coupled to the base and extending a length away from the base and each having an outer edge;
• a structural member connected to at least one of said tangs sufficient to resist compression and increase an urging force applied to said outer edges sufficient to displace said tangs towards each other;
• said opposed walls being cooperative with said tangs when said male part is inserted into said female portion to urge said tang towards each other;
• said length of said tangs being greater than said distance of said walls such that said tangs extend beyond said walls when said male part is sufficiently inserted into said female part, such that said at least one tang abuts said end surface of at least one of said walls to resist withdrawal of said male part from said female part;
• and
• said outer edge of said at leapt one tang being accessible through said female part to permit application of said increased urging force to displace said tangs towards each other to prevent said at least one tang from abutting said end surface of said at least one wall to permit withdrawal of said male part from said female part.
