Abstract
A noncircular-based undulating key-receiving configuration, opposed undulating side walls in said configuration, a centerline within said side walls, with the centerline of the configuration lying within inner and outer noncircular perimeters. A key-receiving configuration containing a first undulating configuration within a second undulating configuration. A key having a first body insertable within a second body with both bodies having undulating key configurations thereon. A key-receiving groove having chamfered edges.
Claims19
A fastener including a noncircular-based undulating key-receiving configuration derived from a circular based undulating key-receiving configuration, said circular based undulating key-receiving configuration having a first centerline which lies between inner and outer circles, said noncircular-based undulating key-receiving configuration comprising opposed undulating side walls, and a second centerline within said opposed undulating side walls, said second centerline lying within inner and outer noncircular perimeters derived from said circular based undulating key-receiving configuration wherein said inner and outer noncircular perimeters are reorientations of said inner and outer circles.
A key-receiving configuration comprising an undulating groove, and chamfered edges in said groove, said undulating groove being based on a noncircular configuration, and a second undulating key-receiving groove positioned relative to said undulating groove.
A key-receiving configuration comprising a fastener, a first key-receiving undulating groove on said fastener, and a second key-receiving undulating groove on said fastener within said first undulating key-receiving groove.
A key-receiving configuration comprising a fastener, a first key-receiving undulating configuration on said fastener, and a second key-receiving undulating configuration on said fastener within said first undulating key-receiving configuration, both of said first and second undulating configurations being derived from noncircular configurations which are based on ovals.
A key-receiving configuration comprising a fastener, a first key-receiving undulating configuration on said fastener, and a second key-receiving undulating configuration on said fastener within said first undulating key-receiving configuration, a key for said key-receiving configuration, a first mating undulating key configuration for mating with said first key-receiving undulating configuration, a second undulating key configuration for mating with said second key-receiving undulating configuration, both of said key-receiving undulating configurations and both of said undulating key configurations being derived from noncircular configurations, said first mating undulating key configuration being located on a first body, and said second undulating key configuration being located on a second body.
A key comprising a first body, a first undulating key configuration on said body, a second body, a second undulating key configuration on said second body, said first body being mountable on said second body for effecting simultaneous engagement between said first undulating key configuration with a first undulating key-receiving configuration and between said second undulating key configuration with a second undulating key-receiving configuration.
