Abstract
Abstract A slide locking assembly for use with chain members of jewelry articles such as necklaces, bracelets and the like comprising a housing for receiving said chain members, said housing comprising inner and outer case sections, means for maintaining separation between the chain members, and spring means for urging portions of said chain members into contact with the housing to produce a frictional drag thereon, wherein the component parts of such an assembly may be easily hand assembled by snap-fit locking engagement of the mating case sections.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
179 words
In a chain assembly including chain members for necklace constructions and the like, a slide locking assembly through which said chain members extend, said slide assembly comprising a housing having inner and outer case sections, said inner case having a bottom wall, upstanding side walls connected thereto and a centrally positioned integral tab upstanding from each end thereof, said side walls and said tabs defining longitudinally orientated channels along said inner case for receiving and maintaining separation between said chain members, said outer case having a generally planar top and side walls downwardly extending therefrom, said inner case side walls having a plurality of inwardly extending depressions therein, said outer case side walls having a plurality of inwardly extending projections thereon, said projections adapted for snap-fit engagement within said depressions when said inner and outer case sections are assembled, and spring means supported by said inner case bottom wall for urging said chain members into frictional contact with said outer case top wall, whereby varied relative positions between said chain members and said slide locking assembly may be maintained.
Claim 2
Dependent Claim
179 words
In a chain assembly including chain members for necklace constructions and the like, a slide locking assembly through which said chain members extend, said slide assembly comprising a housing having inner and outer case sections, said inner case having a bottom wall, upstanding side walls connected thereto and a centrally positioned integral tab upstanding from each end thereof, said side walls and said tabs defining longitudinally orientated channels along said inner case for receiving and maintaining separation between said chain members, said outer case having a generally planar top and side walls downwardly extending therefrom, said inner case side walls having a plurality of inwardly extending depressions therein, said outer case side walls having a plurality of inwardly extending projections thereon, said projections adapted for snap-fit engagement within said depressions when said inner and outer case sections are assembled, and spring means supported by said inner case bottom wall for urging said chain members into frictional contact with said outer case top wall, whereby varied relative positions between said chain members and said slide locking assembly may be maintained.
Claim 3
Dependent Claim
38 words
In the chain assembly of claim 1, said spring means comprising a leaf spring upwardly bowed centrally thereof, thus reducing the height of said longitudinal channels centrally thereof anc consequently increasing the frictional drag on said chain members.
Claim 4
Dependent Claim
33 words
In the chain assembly of claim 1, said outer case side wall projections including at least gently sloped lower portions thereof for initial sliding contact with portions of said inner case side walls.
Claim 5
Dependent Claim
22 words
In the chain assembly of claim 1, said outer case side wall projections comprising dimples inwardly upset from side wall portions thereof.
Claim 6
Dependent Claim
26 words
In the chain assembly of claim 4, said inner case depressions comprising openings extending completely through said inner case side wall, said openings receiving said dimples.
Claim 7
Dependent Claim
24 words
In the chain assembly of claim 1, said outer case side walls having a slight outward taper for receiving said inner case side walls.
Claim 8
Dependent Claim
28 words
In the chain assembly of claim 1, said tabs contacting said spring means so as to prevent lengthwise movement of said spring means relative to said inner case.
Claim 9
Dependent Claim
63 words
In the chain assembly of claim 7, said slide locking assembly including a generally planar separator plate supported by said inner case bottom wall and retained from relative lengthwise movement therewith by said tabs, said plate having inwardly spaced upstanding longitudinally oriented walls further dividing each of said channels into primary and secondary chain member receiving channels, said primary channels being centrally positioned.
Claim 10
Dependent Claim
58 words
In the chain assembly of claim 8, there being two primary channels and two secondary channels, said primary channels having a single leaf spring retained by said tabs and said plate walls, each of said secondary channels having a separate leaf spring respectively retained on either side thereof by a plate wall and an inner case side wall.
Claim 11
Dependent Claim
30 words
In the chain assembly of claim 9, said secondary channel leaf springs being retained from relative lengthwise movement by lugs upwardly extending from end wall portions of said separator plate.
