Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
94 words
A shock-absorbing article provided with means for receiving fasteners, wherein said means comprise wire spirals; a wire bunch defined by a bundle of wires and at least one wire wound about said bundle of wires; said spirals being pressed with said wire bunch; said wire spirals being laid uniformly in density both in thickness and over an article area; and said bunch being placed uniformly throughout the area of the article in turns with said turns of the bunch being displaced relative to each other and either of which encompasses in succession said fasteners.
Claim 2
Dependent Claim
94 words
A shock-absorbing article provided with means for receiving fasteners, wherein said means comprise wire spirals; a wire bunch defined by a bundle of wires and at least one wire wound about said bundle of wires; said spirals being pressed with said wire bunch; said wire spirals being laid uniformly in density both in thickness and over an article area; and said bunch being placed uniformly throughout the area of the article in turns with said turns of the bunch being displaced relative to each other and either of which encompasses in succession said fasteners.
Claim 3
Dependent Claim
27 words
The article as claimed in claim 1 in which the article is of ring-type, and the wire bunch is laid in the form of an Archimedean spiral.
Claim 4
Dependent Claim
85 words
The article as claimed in claim 1 in which the article is bell-shaped and provided with a central bore for receiving a fastener, the wire bunch turns being uniformly distributed throughout the article area in a space between the central bore and an external edge of the article; each wire bunch turn being laid approximating in shape an isoceles triangle, the sides of the triangle being located radially, a vertex encompassing the central bore and a base disposed along the external edge of the article.
Claim 5
Independent Claim
94 words
A method for producing a ring-type article comprising forming a blank from wire spirals; laying a wire bunch defined by a bundle of wires and at least one wire wound about said bundle of wires along the blank surface; coiling said blank together with the wire bunch laid thereon; pressing said coiled blank and wire bunch in a die complementary in shape to the shape of the article being produced, by directing a pressing force along a coil axis and by laying the wire bunch during pressing in the form of an Archimedean spiral.
Claim 6
Independent Claim
94 words
A method for producing a ring-type article comprising forming a blank from wire spirals; laying a wire bunch defined by a bundle of wires and at least one wire wound about said bundle of wires along the blank surface; coiling said blank together with the wire bunch laid thereon; pressing said coiled blank and wire bunch in a die complementary in shape to the shape of the article being produced, by directing a pressing force along a coil axis and by laying the wire bunch during pressing in the form of an Archimedean spiral.
Claim 7
Dependent Claim
18 words
The method as claimed in claim 4 in which said at least one wire is a wire spiral.
Claim 8
Dependent Claim
17 words
The method as claimed in claim 4 in which said at least one wire has helical portions.
Claim 9
Dependent Claim
35 words
The method as claimed in claim 5 in which said bundle is preliminarily wound with a wire spiral by applying tension and with a pitch which is equal to a diameter of the wire spiral.
Claim 10
Dependent Claim
29 words
The method as claimed in claim 7 in which said bundle is preliminarily wound with a wire having helical portions with a second pitch amounting to 5-8 wire diameters.
Claim 11
Dependent Claim
22 words
The method as claimed in claim 5 in which a bunch upon being wound is laid in the form of a zigzag.
Claim 12
Independent Claim
149 words
A method for producing a bell-shaped article provided with a central bore for receiving a fastener, comprising forming a first blank of wire spirals; forming a second blank of a wire bunch defined by a bundle of wires and at least one wire wound about said bundle of wires by laying the wire bunch in turns on a fixture having a centrally located rod and pins positioned at the periphery and spaced apart at one and the same distance from the rod so that each wire bunch turn encompasses the rod and several pins, with each subsequent turn being displaced in relation to the preceding turn whereby the turns approximate in shape an isosceles triangle whose sides are located radially, the vErtex encompassing the rod and the base extending along an external edge of the article encompassing several pins; and forcing the first blank together with the second blank.
Claim 13
Independent Claim
149 words
A method for producing a bell-shaped article provided with a central bore for receiving a fastener, comprising forming a first blank of wire spirals; forming a second blank of a wire bunch defined by a bundle of wires and at least one wire wound about said bundle of wires by laying the wire bunch in turns on a fixture having a centrally located rod and pins positioned at the periphery and spaced apart at one and the same distance from the rod so that each wire bunch turn encompasses the rod and several pins, with each subsequent turn being displaced in relation to the preceding turn whereby the turns approximate in shape an isosceles triangle whose sides are located radially, the vErtex encompassing the rod and the base extending along an external edge of the article encompassing several pins; and forcing the first blank together with the second blank.
Claim 14
Dependent Claim
18 words
The method as claimed in claim 10 in which said at least one wire is a wire spiral.
Claim 15
Dependent Claim
17 words
The method as claimed in claim 10 in which said at least one wire has helical portions.
Claim 16
Dependent Claim
32 words
The method as claimed in claim 11 in which said bundle is preliminarily wound with a wire spiral by applying a requisite tension and with a pitch equalling a wire spiral diameter.
Claim 17
Dependent Claim
28 words
The method as claimed in claim 12 in which said bundle is preliminarily wound with a wire having helical portions with a pitch amounting to 5-8 wire diameters.
Claim 18
Dependent Claim
22 words
The method as claimed in claim 11 is which a bunch upon being wound is laid in the form of a zigzag.
