Abstract
Abstract An outsole for a sports shoe which enables it to be used for a wider range of different types of ground than is possible with the known outsoles. The sole is provided with profile projections which are each formed by at least two elongated profile bodies which are close together or joined at one end and diverge towards the other end to radiate on one side only of the projection. The projections when stressed counter to the direction of divergence of the profile bodies provide increased support, but provide less support when stressed in the opposite direction. This is particularly true if the profile bodies are constructed of a springily resilient material. By appropriately arranging the profile bodies on the outsole, controlled account can be taken of the requirements in respect of safety against slipping and the sliding characteristics, of the sport shoe.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
114 words
An outsole for a sports shoe comprising an outsole member of resilient material having a lower face, a plurality of profile projections projecting out of said lower face, said profile projections each comprising three to four elongate profile bodies having two ends, said profile bodies in each case being located close to one another at one end and diverging from one another from said one end and forming acute angles between their longitudinal axes, each acute angle having a value such that all profile bodies of each projection are disposed within a sector of less than 180°, each of the profile bodies tapering at least from its longitudinal center gradually towards its other end.
Claim 2
Dependent Claim
114 words
An outsole for a sports shoe comprising an outsole member of resilient material having a lower face, a plurality of profile projections projecting out of said lower face, said profile projections each comprising three to four elongate profile bodies having two ends, said profile bodies in each case being located close to one another at one end and diverging from one another from said one end and forming acute angles between their longitudinal axes, each acute angle having a value such that all profile bodies of each projection are disposed within a sector of less than 180°, each of the profile bodies tapering at least from its longitudinal center gradually towards its other end.
Claim 3
Dependent Claim
37 words
An outsole as claimed in claim 1, wherein the elongate profile bodies are joined to one another at said one end from which they extend in a diverging manner, whereby said bodies form a one-piece profile projection.
Claim 4
Dependent Claim
42 words
An outsole as claimed in claim 1, wherein the height of at least some of the profile bodies increases above said outer face of the outsole from said ends which are close to one another in the direction of their other ends.
Claim 5
Dependent Claim
29 words
An outsole as claimed in claim 3, and further comprising a tread surface of said profile bodies, which tread surface slopes upwards from said outer face of the outsole.
Claim 6
Dependent Claim
44 words
An outsole as claimed in claim 4, wherein only the profile bodies of the profile projections located in the region of the inner ball of the foot of the wearer have a tread surface which is parallel to the outer face of the outsole.
Claim 7
Dependent Claim
17 words
An outsole as claimed in claim 1, wherein the profile bodies also taper towards said one end.
Claim 8
Dependent Claim
17 words

Claim 9
Dependent Claim
16 words
An outsole as claimed in claim 6, wherein the profile bodies are of a triangular outline.
Claim 10
Dependent Claim
62 words
An outsole as claimed in claim 1, wherein the sole member comprises a front sole portion and a rear sole portion and wherein the majority of the profile projections on the front sole portion are located with the profile bodies diverging backwards and at least some of the profile projections on the rear sole are located with the profile bodies diverging forwards.
Claim 11
Dependent Claim
29 words
An outsole as claimed in claim 4, wherein the profile projections with the profile bodies diverge laterally with respect to, and are located along the edge of the sole.
Claim 12
Dependent Claim
17 words
An outsole as claimed in claim 1, wherein said profile projections are integral with the outsole member.
Claim 13
Dependent Claim
28 words
An outsole as claimed in claim 1, wherein the lateral surfaces which delimit said profile bodies are essentially at right angles to said outer face of the outsole.
Claim 14
Dependent Claim
18 words
An outsole as claimed in claim 1, wherein the profile bodies taper to form a pointed other end.
Claim 15
Dependent Claim
19 words
An outsole as claimed in claim 1, wherein the profile bodies are disposed within a sector of approximately 90°.
