Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
159 words
A picture framing clip adapted to mount over the edges and secure together a plurality of planar sheets to form a picture frame, said clip comprising: a. a generally U-shaped channel member having opposing front and rear wall portions, said front wall portion being adapted to engage one side of said plurality of sheets; b. resilient clamp means slidably mounted on the rear wall portion of said channel member and configured, dimensioned, and positioned to engage the opposite side of said plurality of sheets and to be put into spring-biased relation to said plurality of sheets; and c. locking means for securing said resilient clamp means in spring-biased relation to the opposite side of said plurality of sheets when the clamp means is slidably displaced to a first position with respect to said channel member and for releasing the clamp means when the resilient clamp means is slidably displaced to a second position with respect to the channel member.
Claim 2
Dependent Claim
159 words
A picture framing clip adapted to mount over the edges and secure together a plurality of planar sheets to form a picture frame, said clip comprising: a. a generally U-shaped channel member having opposing front and rear wall portions, said front wall portion being adapted to engage one side of said plurality of sheets; b. resilient clamp means slidably mounted on the rear wall portion of said channel member and configured, dimensioned, and positioned to engage the opposite side of said plurality of sheets and to be put into spring-biased relation to said plurality of sheets; and c. locking means for securing said resilient clamp means in spring-biased relation to the opposite side of said plurality of sheets when the clamp means is slidably displaced to a first position with respect to said channel member and for releasing the clamp means when the resilient clamp means is slidably displaced to a second position with respect to the channel member.
Claim 3
Dependent Claim
37 words
A picture framing clip as in claim 1, wherein said resilient clamp means is a curved leaf spring having first and second ends which is slidably mounted at one of said ends on said rear wall portion.
Claim 4
Dependent Claim
60 words
A picture framing clip as in claim 2, wherein said locking means secures the other end of said curved leaf spring to said rear wall portion in a position where the curved portion of said curved leaf spring extends toward said front wall portion to clamp said plurality of sheets between said curved leaf spring and said front wall portion.
Claim 5
Dependent Claim
33 words
A picture framing clip as in claim 3, wherein said curved leaf spring includes means for increasing the coefficient of friction of the surface of said spring that faces said front wall portion.
Claim 6
Dependent Claim
94 words
A picture framing clip as in claim 3, wherein said rear wall portion defines an aperture having a tab window and said locking means comprises a locking tab secured to said curved leaf spring, said tab window being aligned with said locking tab when said curved leaf spring is in a first position and said locking tab being moved out of alignment with said tab window when said curved leaf spring is slidably displaced relative to said first position to lock said other end of said curved leaf spring to said rear wall portion.
Claim 7
Dependent Claim
52 words
A picture framing clip as in claim 3, wherein said rear wall portion includes an aperture and said aperture is provided with a first edge having a relatively high friction surface and a second edge defined by a section of said rear wall portion which is indented toward said front wall portion.
Claim 8
Dependent Claim
71 words
A picture framing clip as in claim 3, wherein said rear wall portion includes an aperture and said curved leaf spring is mounted on said rear wall portion by extending through said aperture, said aperture being elongated in shape and allowing said curved spring to slide in said aperture, said curved leaf spring including relatively large portions disposed on both sides of said aperture to maintain said spring within said aperture.
Claim 9
Dependent Claim
95 words
A picture framing clip as in claim 7, wherein said rear wall portion defines a second aperture having a tab window and said locking means comprises a locking tab secured to said curved leaf spring, said tab window being Aligned with said locking tab when said curved leaf spring is in a first position and said locking tab being moved out of alignment with said tab window when said curved leaf spring is slidably displaced relative to said first position to lock said other end of said curved leaf spring to said rear wall portion.
Claim 10
Dependent Claim
28 words
A picture framing clip as in claim 8, further comprising a second spring for urging said second end of said curved spring away from said front wall portion.
