Abstract
Abstract A hanger clip intended for supporting decorations and the like from the hanger bars of conventional acoustical ceiling structures, the clip being designed for ready attachment to the flanges or arms of such a bar under its own inherent resiliency and further being designed to yeild under a predetermined load suspended therefrom in order to prevent damage to the hanger bar or its conventional suspension. In a preferred form, the clip is an integral, injection-molding comprising a simple strip of inherently resiliently flexible synthetic plastic provided, at its opposite ends, with finger pairs projecting from a common surface of the strip to define, when the strip is bent to cross its ends, mutually facing, open mouths for engagement with such hanger bar arms, said fingers being formed of inherently brittle synthetic plastic material.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
155 words
For use with a wire-suspended hanger bar having substantially an inverted-T cross section and supporting an edge of a panel on each of its oppositely extending arms, a hanger clip comprising a body portion and a jaw portion, the body portion having opposed sides resiliently biased apart and the jaw portion comprising opposed jaws respectively connected to said body sides but oppositely arranged relative thereto whereby movement of said body sides toward each other against their bias will separate said jaws, each of said jaws having, at its distal end, an open mouth proportioned and designed, when such panels are slightly lifted off their hanger bar arms, snugly to receive an arm of such a hanger bar whereby said clip will be suspended from such a bar, said clip being formed with a weakened region to prevent the transmission through said clip of a load sufficient to damage such a hanger bar or its suspension.
Claim 2
Dependent Claim
155 words
For use with a wire-suspended hanger bar having substantially an inverted-T cross section and supporting an edge of a panel on each of its oppositely extending arms, a hanger clip comprising a body portion and a jaw portion, the body portion having opposed sides resiliently biased apart and the jaw portion comprising opposed jaws respectively connected to said body sides but oppositely arranged relative thereto whereby movement of said body sides toward each other against their bias will separate said jaws, each of said jaws having, at its distal end, an open mouth proportioned and designed, when such panels are slightly lifted off their hanger bar arms, snugly to receive an arm of such a hanger bar whereby said clip will be suspended from such a bar, said clip being formed with a weakened region to prevent the transmission through said clip of a load sufficient to damage such a hanger bar or its suspension.
Claim 3
Dependent Claim
106 words
A hanger clip comprising an integral strip of resiliently flexible material formed to provide a body portion and a jaw portion, the body portion having opposed sides resiliently biased apart by the inherent resiliency of said strip and the jaw portion comprising opposed jaws oppositely arranged relative to said opposed sides whereby movement of said body sides toward each other against their bias will separate said jaws, each of said jaws having an open mouth and said mouths opening toward each other, said clip being formed in its jaw portion with a weakened region to limit the load-bearing capacity of the clip to a predetermined value.
Claim 4
Dependent Claim
106 words
A hanger clip comprising an integral strip of resiliently flexible material formed to provide a body portion and a jaw portion, the body portion having opposed sides resiliently biased apart by the inherent resiliency of said strip and the jaw portion comprising opposed jaws oppositely arranged relative to said opposed sides whereby movement of said body sides toward each other against their bias will separate said jaws, each of said jaws having an open mouth and said mouths opening toward each other, said clip being formed in its jaw portion with a weakened region to limit the load-bearing capacity of the clip to a predetermined value.
Claim 5
Dependent Claim
38 words
A hanger clip comprising a strip of resiliently flexible material provided, adjacent each of its ends, with a pair of fingers extending in a common direction from the same face of said strip to define an open mouth.
Claim 6
Dependent Claim
38 words
A hanger clip comprising a strip of resiliently flexible material provided, adjacent each of its ends, with a pair of fingers extending in a common direction from the same face of said strip to define an open mouth.
Claim 7
Dependent Claim
29 words
The hanger clip of claim 3 in which the distal finger of at least one pair is formed of a material more frangible than the material of said strip.
Claim 8
Dependent Claim
27 words
The hanger clip of claim 3 in which the distal finger of each pair is formed of a material more frangible than the material of said strip.
Claim 9
Dependent Claim
41 words
The hanger clip of claim 3 in which the base of at least one finger pair is weakened to provide for separation of the fingers of said pair under a load which is insufficient to break the body of said strip.
Claim 10
Dependent Claim
46 words
The hanger clip of claim 3 in which the clip is an integral injection-molding, the body of said strip being formed from an inherently resiliently flexible synthetic plastic and the ends of said strip including the finger pairs being formed from an inherently brittle synthetic plastic.
Claim 11
Dependent Claim
106 words
A hanger clip comprising an integral strip of resiliently flexible material formed to provide a body portion and a jaw portion, the body portion having opposed sides resiliently biased apart by the inherent resiliency of said strip and the jaw portion comprising opposed jaws oppositely arranged relative to said opposed sides whereby movement of said body sides toward each other against their bias will separate said jaws, each of said jaws having an open mouth and said mouths opening toward each other, said clip being formed in its jaw portion with a weakened region to limit the load-bearing capacity of the clip to a predetermined value.
Claim 12
Dependent Claim
106 words
A hanger clip comprising an integral strip of resiliently flexible material formed to provide a body portion and a jaw portion, the body portion having opposed sides resiliently biased apart by the inherent resiliency of said strip and the jaw portion comprising opposed jaws oppositely arranged relative to said opposed sides whereby movement of said body sides toward each other against their bias will separate said jaws, each of said jaws having an open mouth and said mouths opening toward each other, said clip being formed in its jaw portion with a weakened region to limit the load-bearing capacity of the clip to a predetermined value.
Claim 13
Dependent Claim
38 words
A hanger clip comprising a strip of resiliently flexible material provided, adjacent each of its ends, with a pair of fingers extending in a common direction from the same face of said strip to define an open mouth.
Claim 14
Dependent Claim
38 words
A hanger clip comprising a strip of resiliently flexible material provided, adjacent each of its ends, with a pair of fingers extending in a common direction from the same face of said strip to define an open mouth.
Claim 15
Dependent Claim
29 words
The hanger clip of claim 3 in which the distal finger of at least one pair is formed of a material more frangible than the material of said strip.
Claim 16
Dependent Claim
27 words
The hanger clip of claim 3 in which the distal finger of each pair is formed of a material more frangible than the material of said strip.
Claim 17
Dependent Claim
41 words
The hanger clip of claim 3 in which the base of at least one finger pair is weakened to provide for separation of the fingers of said pair under a load which is insufficient to break the body of said strip.
Claim 18
Dependent Claim
46 words
The hanger clip of claim 3 in which the clip is an integral injection-molding, the body of said strip being formed from an inherently resiliently flexible synthetic plastic and the ends of said strip including the finger pairs being formed from an inherently brittle synthetic plastic.
