Muntin grid and joiner

A muntin bar joiner comprising:

• a) a relatively flat, thin body;
• b) a first muntin bar engagement leg extending from one end of said body;
• c) a second muntin bar engagement leg extending from an end of said body opposite to said one end;
• d) said muntin bar engagement legs extending along a longitudinal axis of said joiner, said body having opposite sides defining substantially parallel major surfaces having substantially parallel opposite edges extending substantially parallel to said axis;
• and,
• e) first and second muntin bar abutments projecting from said body in a direction transverse to said axis, each abutment comprising a muntin bar abutment face oriented in a direction transverse to said axis, with said abutment faces facing in opposite axial directions, one of said abutments constructed for making latching engagement with a muntin bar, said one abutment comprising a resiliently deflectable finger extending from one of said edges.

A muntin bar grid comprising a muntin bar joiner detachably joining three tubular muntin bars comprising:

• a) a flat, thin joiner body having a longitudinal axis with opposite edges extending in the direction of said axis and opposite sides defining major faces, said joiner body extending transverse to a first muntin bar through a slit in said first muntin bar;
• b) a first leg projecting from said body and said first muntin bar and telescoping into a second muntin bar, said first leg engaging the second muntin bar to maintain said second muntin bar aligned with said axis in fixed relationship said joiner;
• c) a second leg projecting from said body and said first muntin bar and telescoping into a third muntin bar, said second leg engaging the third muntin bar to maintain said third muntin bar aligned with said axis in fixed relationship with said joiner;
• d) first and second abutments extending from said body in a direction transverse to said axis, each abutment comprising an abutment face oriented in a direction transverse to said axis for engaging said first muntin bar, said abutment faces facing in opposite axial directions, at least one of said abutment faces formed by an abutment member that extends through an opening in said joiner body and engages said first muntin bar.

A muntin bar joiner comprising:

• a) a relatively flat, thin body having opposite major faces and substantially parallel side edges extending between ends of the body;
• b) a first muntin bar engagement leg continuous with the body and extending from one end of said body;
• c) a second muntin bar engagement leg continuous with the body and extending from an end of said body opposite to said one end;
• d) said muntin bar engagement legs extending along a longitudinal axis of said joiner;
• and, e) first and second locking abutments extending from said body in a direction transverse to said axis for engagement with a muntin bar to lock the body in position against movement in the direction of the axis, at least one of said abutments resiliently deflectable by engagement with a muntin bar.
