Abstract
Abstract A holding clip made of resilient material has bent end portions for engaging and retaining an article. The bent end portions are stiffened relative to the body of the clip by stiffening members which are substantially similarly bent. The thickness of resilient material inwardly of the stiffening member is greater, at least over part of the bent end portion, than at a position opposite the said part on the outward side of the stiffening member.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
121 words
A holding clip comprising a strip of resilient material, the strip having two end portions of a bent configuration such as to form respective substantially U-shaped portions, each end portion being stiffened by a substantially U-shaped stiffening member embedded therein, each U-shaped stiffening member having its free limbs embedded in the assoCiate end portion in a displaced position relative thereto such that the thickness of material on the inwardly facing side of the clip increases along each of the three limbs of the respective U-shaped stiffening member, the lesser thickness of resilient material at said inwardly facing side of each said limb being at the end of each said limb which is towards the free end of the respective end portions.
Claim 2
Dependent Claim
121 words
A holding clip comprising a strip of resilient material, the strip having two end portions of a bent configuration such as to form respective substantially U-shaped portions, each end portion being stiffened by a substantially U-shaped stiffening member embedded therein, each U-shaped stiffening member having its free limbs embedded in the assoCiate end portion in a displaced position relative thereto such that the thickness of material on the inwardly facing side of the clip increases along each of the three limbs of the respective U-shaped stiffening member, the lesser thickness of resilient material at said inwardly facing side of each said limb being at the end of each said limb which is towards the free end of the respective end portions.
Claim 3
Dependent Claim
19 words
A clip according to claim 1 wherein the two free limb portions of said bent end portions extend divergently.
Claim 4
Dependent Claim
57 words
A clip according to claim 1 wherein a center body portion extending between said bent end portions has end regions which enclose the facing free ends of said stiffening members and are formed as substantially loaf-shaped portions which are enlarged with respect to the middle region of the center body portion which lies between said end regions.
Claim 5
Dependent Claim
42 words
A clip according to claim 1 wherein transverse bores are formed in the clip in said bent end portions, said bores being capable in use of the clip of accommodating additional retaining clasp means to secure the clip in a holding position.
Claim 6
Dependent Claim
24 words
A clip according to claim 4 wherein said bores are formed in regions of the clip with an increased thickness of resilient material. 1
Claim 7
Dependent Claim
38 words
A clip according to claim 1 wherein a center body portion extends between said bent end portions and said bent end portions form an angle with their respective limb portions which are joined by said center body portion.
Claim 8
Dependent Claim
28 words
A clip according to claim 1 wherein a center body portion between said bent end portions is of a non-rectilinear configuration, whereby its spring working length is extended.
Claim 9
Dependent Claim
31 words
A clip according to claim 1 wherein a center body portion between said bent end portions is divided into at least two limb parts which are preferably of different elasticity constants.
Claim 10
Dependent Claim
28 words
A clip according to claim 1 wherein the ends of the free limb portions of said bent end portions are extended to form inwardly directed resilient tongue portions.
Claim 11
Dependent Claim
43 words
A clip according to claim 1 wherein the resilient material enclosing the stiffening members at least at their free ends is of an elasticity intermediate between that of the stiffening members and that of the resilient material of the remainder of said strip.
Claim 12
Dependent Claim
72 words
A clip according to claim 1 wherein a center body portion extends between said bent end portions and includes a resilient middle region and end regions which enclose facing free ends of said stiffening members, said middle region being partly separated from each said end regions by respective slot means and the effective elastic length of said middle region being greater than the distance between said two ends of said stiffening members.
