Corner fastener for hollow section members

A corner fastener for use in securing first and second frame members together to form a corner of a frame, the first frame having spaced apart outside and inside walls thereby defining a cavity, the cavity defining a first and second detent engaging member, the second frame having an outer wall, the outer wall having an opening in general axial alignment with the cavity, said fastener comprising:

• (a) a body generally sized to be inserted in the cavity said body comprising:
• (i) a first section operatively connected to a second section by hinge means, wherein said first and second sections are generally adjacent when manufactured, but are folded on top of each other during use;
• (ii) said first detent engaging member has a first end operatively connected to said first section and a second end free to move between an unengaged and an engaged position;
• and
• (iii) said second detent engaging member has a first end operatively connected to said second section and a second end free to move between an unengaged and an engaged position;
• and
• (b) said body defining a fastening member aperture, said aperture in general axial alignment with the opening, wherein when, said body is positioned in the cavity and when a fastening member is inserted in the opening and said aperture, said detent engaging member is locked in the detent by the fastening member, thereby fastening the first and second frame members together.

A frame corner comprising:

• (a) a first frame having spaced apart outside and inside walls thereby defining a cavity, the cavity defining at least one detent;
• (b) a second frame having an outer wall, the outer wall having an opening in general alignment with the cavity;
• and
• (c) a corner fastener for use in securing said first and second frame members together, said fastener comprising:
• (i) a body generally sized to be inserted in the cavity, said body comprising a first section operatively connected to a second section by hinge means, wherein said first and second sections are generally adjacent when manufactured, but are folded on top of each other during use;
• (ii) locking means having a first end operatively connected to said body and a second end free to move between an unengaged position and an engaged position, said locking means having a detent engaging member;
• (iii) said body defining a fastening member aperture, said aperture in general axial alignment with the opening;
• and
• (iv) a fastening member for operative engagement with said locking means wherein when said body is positioned in the cavity and when a fastening member is inserted in the opening and said aperture, said detent engaging member is located in the detent by the fastening member, thereby fastening the first and second frame members together.
