Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
109 words
A one-piece snap hinge of plastic material with the following features: (a) Two hinge parts (1, 2), collapsible about a geometrical main axis (4), are hinge-connected by means of thin-spots (9, 9.1, 10, 10.1 etc.) to, at least, one intermediate element (5, 5.1 etc.); (b) the hinge parts (1, 2), in addition, are hinge- connected with each other by means of a film hinge (7, 16), falling into the main axis (4), characterized in that the thin-spots (9, 10 etc.), limiting one intermediate element, from an imaginary point, situated on the geometrical main axis (4), diverge in astraight or curved manner and extend diagonally to the geometrical main axis.
Claim 2
Dependent Claim
109 words
A one-piece snap hinge of plastic material with the following features: (a) Two hinge parts (1, 2), collapsible about a geometrical main axis (4), are hinge-connected by means of thin-spots (9, 9.1, 10, 10.1 etc.) to, at least, one intermediate element (5, 5.1 etc.); (b) the hinge parts (1, 2), in addition, are hinge- connected with each other by means of a film hinge (7, 16), falling into the main axis (4), characterized in that the thin-spots (9, 10 etc.), limiting one intermediate element, from an imaginary point, situated on the geometrical main axis (4), diverge in astraight or curved manner and extend diagonally to the geometrical main axis.
Claim 3
Dependent Claim
26 words
Snap hinge according to claim 1, characterized in that (in each case) two intermediate elements are opposed to one another with their narrow, particularly acute, ends.
Claim 4
Dependent Claim
24 words
Snap hinge according to claim 1, characterized in that (in each case) two intermediate elements are opposed to one another with their wide ends.
Claim 5
Dependent Claim
28 words
Snap hinge according to claim 3, characterized in that the wide ends of the intermediate elements are separated from one another by a material opening (19) (Figure 14).
Claim 6
Dependent Claim
30 words
Snap hinge according to claim 3, characterized in that the wide ends of the intermediate elements are separated from one another by, at least, one bending groove (30) (Figure 19).
Claim 7
Dependent Claim
39 words
Snap hinge according to one of the preceding claims characterized in that the intermediate elements are springs and have the shape of grooves, enlarging in the direction of the geometrical main axis (Figures 1 through 14, 19 through 22).
Claim 8
Dependent Claim
19 words
Snap hinge according to claim 6, characterized in that the grooves have an arc-shaped cross-section (Figures 1 through 7).
Claim 9
Dependent Claim
24 words
Snap hinge according to claim 6, characterized in that the grooves have a V-shaped or multi-cornered cross-section (Figures 8, 13, 14, 19 through 22).
Claim 10
Dependent Claim
45 words
Snap hinge according to one of claims 6 through 8, characterized in that the groove- shaped intermediate elements, in case of arrangement of the snap hinge on a closable subject, in the closing position project into the interior of the subject (Figures 1 through 4).
Claim 11
Dependent Claim
48 words
Snap hinge according to one of claims 6 trough 8, characterized in that the groove- shaped intermediate elements, in case of arrangement of the snap hinge on a closable subject, in the closing position of te subject, are directed outwards (Figures 6, 7, 13, 14, 19 through 22).
Claim 12
Dependent Claim
58 words
Snap hinge according to one of claims 1 through 5, characterized by the following features: (a) The intermediate elements (5.6) are tension elements of low to infinitely small elasticity of tension; (b) at least, one of the hinge parts (1, 2) is provided springily, particularly bending-elastically, in the neighbourhood of the geometrical main axis (Figures 15 through 18).
Claim 13
Dependent Claim
18 words
Snap hinge according to claim 11, characterized in that the intermediate elements are plane (Figures 15 through 18).
Claim 14
Dependent Claim
46 words
Snap hinge according to one of claims 1 through 5, characterized by the following features: (a) The snap hinge consists of deep-drawn, bending-elastical plastic foil; (b) the intermediate elements (5.7) comprise each, at least, two deep-drawn grooves, which form the thin-spots (9.3,10.3) (Figures 19 through 22).
Claim 15
Dependent Claim
25 words
Snap hinge according to claim 13, characterized in that the grooves are separated from one another and from the hinge parts by ribs (25, 26).
Claim 16
Dependent Claim
24 words
Snap hinge according to claim 14, characterized in that the grooves extend separately from one another to the narrow ends of the intermediate elements.
Claim 17
Dependent Claim
20 words
Snap hinge according to claim 15, characterized in that the narrow ends (32) of the intermediate elements end in grooves.
Claim 18
Dependent Claim
36 words
Snap hinge according to one of claims 14 through 16, characterized in that on the wide ends, directed to one another, of the intermediate elements ribs (28), extending transversely to the geometrical main axis, are provided.
