Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
147 words
A heel comprising a heel base element, a rotatable wear element connected to the heel base element, and a resilient connector having two ends, one of which is continuously connected to the heel base element, and the other end connected to the wear element to permit rotation thereof with respect to the heel base element, said resilient connector being spring-loaded to force a resilient contact between the wear element and the heel base element at all times during the use of the heel, said connector being sufficiently resilient to permit manual separation of the contacting elements axially for relocating the position of the wear element with respect to the heel base element during the further use of the heel, and complementary fastening means having two ends, one end non-rotatably mounted with respect to the base element, and the other non-rotatably mounted with respect to the wear element.
Claim 2
Dependent Claim
147 words
A heel comprising a heel base element, a rotatable wear element connected to the heel base element, and a resilient connector having two ends, one of which is continuously connected to the heel base element, and the other end connected to the wear element to permit rotation thereof with respect to the heel base element, said resilient connector being spring-loaded to force a resilient contact between the wear element and the heel base element at all times during the use of the heel, said connector being sufficiently resilient to permit manual separation of the contacting elements axially for relocating the position of the wear element with respect to the heel base element during the further use of the heel, and complementary fastening means having two ends, one end non-rotatably mounted with respect to the base element, and the other non-rotatably mounted with respect to the wear element.
Claim 3
Dependent Claim
59 words
The heel of claim 1, wherein the complementary fastening means comprise bolt and nut fastening means, and the connecting base and wear elements are provided with interlocking faces during use of the heel, said bolt and nut fastening means having sufficient unitary axial movement to permit separation of the interlocking faces for replacement or adjustment of the wear element.
Claim 4
Dependent Claim
16 words
The heel of claim 2, wherein the bolt fastening means extends integrally from the base element.
Claim 5
Dependent Claim
16 words
The heel of claim 3, wherein the bolt fastening means extends integrally from the wear element.
Claim 6
Dependent Claim
43 words
The heel of claim 1 in which a tube-like portion, open at both ends, extends integrally from one of the elements, the free end of which is provided with an inwardly extending ledge for supporting one of the ends of the resilient connector.
Claim 7
Dependent Claim
59 words
The heel of claim 1, wherein the complementary fastening means comprises a bolt mounted to one of the elements, a nut non-rotatably mounted with respect to the other of said elements, a coiled spring positioned between the nut and the other of the elements, to enable compression of the spring when the elements are in contact with each other.
Claim 8
Dependent Claim
27 words
The heel of claim 1, in which the peripheral edges of the wear element are provided with a finger-engaging surfaces to facilitate separation of the contacting surfaces.
