Insulating glass unit - Patent Review 5678377

Claims

Having described my invention I claim:

1. A clip for securing a muntin bar to a planar spacer frame of an insulating glass unit comprising:

a. bar support for engaging a muntin bar, said bar support projecting from said clip in a first direction and having opposed sides respectively bounded by first and second planes extending in said first direction, said clip being adapted to be installed such that said first and second planes extend parallel to a plane defined by said planar spacer frame; and,

b. latch structure for securing the clip to the spacer frame;

c. said latch structure comprising a plurality of fingers constructed for latching engagement with the spacer frame;

d. said latch structure defining at least two pairs of latching locations engagable with the spacer frame, the latching locations of each pair spaced apart transversely relative to said first and second planes with said first and second planes disposed therebetween and each latching location spaced away from the closest one of said planes.

2. The clip claimed in claim 1 wherein said clip further comprises clip body structure comprising a surface portion adjacent a projecting end of each latch finger, space between each said surface portion and a respective finger being occupied by a spacer frame wall when said latch structure engages said the spacer frame at said locations.

3. The clip claimed in claim 1 further comprising clip body structure connecting the bar support and latch structure, said latch structure comprising a plurality of relatively rigid latch body members projecting from said clip body structure to said latch fingers, said latch fingers extending from the projecting portions of said latch body members back toward said clip body.

4. The clip claimed in claim 3 wherein said clip body structure comprises a plate-like member having opposite ends adapted to be spaced axially apart in the direction of the spacer frame plane when the clip engages the spacer frame and opposite sides adapted to be spaced apart transversely of the spacer frame plane when the clip engages the spacer frame.

5. The clip claimed in claim 4 wherein two spaced apart latch body members extend across said plate-like member between said opposite side, each latch body member defining opposite ends with a respective one of said location adjacent each end of each latch body member.

6. The clip claimed in claim 5 wherein said clip body plate-like member defines surface portions adjacent each projecting ends of each latch finger, space between each said surface portion and a respective latch finger adapted to be occupied by a spacer frame wall when said latch structure engages the spacer frame at said locations, said surface portions and said fingers adapted to coact to prevent dislodgement of the clip from the spacer frame wall, said latch body members each defining a face aligned with said space between said surface portion and each latch finer, said faces adapted to engage the spacer frame wall and limit clip motion axially along the spacer frame.

7. A clip for securing a muntin bar to a frame member of a planar insulating glass unit spacer frame comprising: a bar support for engaging a muntin bar, said bar support being adapted to project from the frame member toward an interior of the unit spacer frame when the clip is secured to the frame member, said bar support comprising opposed sides bounded by respective first and second planes such that upon installation said first and second plane extend parallel to a planes defined by said frame member and opposed ends extending transverse to said sides, said bar support and muntin bar telescopically related when engaged; and, latch structure for securing the clip to the spacer frame comprising first and second latch body members projecting oppositely from said bar support, each said latch body member extending transversely relative to said first and second planes and defining first and second opposite ends spaced apart in a direction transversely relative to the first and second planes, with said first and second planes disposed between said first and second opposite ends, each latch body member defining a securing location adjacent each end thereof with said securing locations each spaced away from the respective closest one of said first and second planes, said latch structure further comprising at least a resilie
