Rotatable brim cap with stabilized track transition interface
View Patent ↗A cap includes an elongate track that extends along the lower edge of the crown has opposing free ends or edges when formed along a generally circular path. A slide, connected to the brim, can slide along the track. A pin or wire aligns the opposing edges of the track when brought into abutment to form an interface parting line. One or more tapes extend across the interface parting line to prevent relative movements of the opposing edges about the pin or wire thereby fixing and stabilizing the opposing edges at the interface parting line to maintain alignment and eliminate discontinuities at the opposing edges to insure smooth movements of the brim independently of the position of said brim along the track.
1. A cap with a rotatable brim comprising a crown having a substantially circular circumferential lower edge to fit on a wearer's head and having an inner surface along said lower edge; a brim having an arcuate edge attached to said crown and extending substantially outwardly away from said crown; an elongate track extending along said circumferential lower edge attached to said inner surface and having opposing free ends or edges when formed along a generally circular path; an elongate slide having a length substantially equal to said arcuate edge and connected to said brim along said arcuate edge, said track and slide forming interlocking means for allowing movements of said elongate slide only along the entire length of said elongate track; first alignment means for aligning said opposing edges when brought into abutment to form a substantially continuous track with an interface parting line; and second alignment means extending across at least a portion of said interface parting line to prevent relative movements of said opposing edges about said first alignment means, whereby said first and second alignment means fix and stabilize said opposing free ends or edges at said interface parting line to maintain alignment and eliminate discontinuities of said opposing edges in said elongate track to insure smooth movements of said brim independently of the position of said brim along said elongate track.
2. A cap as defined in claim 1 , wherein said elongate track comprises an elongate generally flat strip portion and an enlarged generally transverse portion along an elongate edge of said flat strip portion to form a generally uniform T-shaped cross-section along the entire length of said elongate track.
3. A cap as defined in claim 2 , wherein said flat strip portion defines a connecting surface; and attachment means for attaching said connecting surface to said crown inner surface.
4. A cap as defined in claim 3 , wherein said attachment means comprises stitching.
5. A cap as defined in claim 3 , wherein said attachment means comprises an adhesive bond.
6. A cap as defined in claim 3 , wherein said attachment means comprises a weld or seal bond.
7. A cap as defined in claim 2 , wherein said elongate slide comprises an elongate channel having a uniform cross-section generally in the shape of a “C” having a longitudinal slot for passage of said flat strip portion with clearance and for slidingly receiving said transverse portion of said elongate track.
8. A cap as defined in claim 7 , wherein said transverse portion has a generally triangular cross-section with an apex directed from said flat strip portion, said elongate channel being provided with a longitudinal internal groove opposite to said longitudinal slot for receiving at least an edge of said transverse portion formed along said apex, said groove being dimentioned to provide a substantially uniform thickness cross-section of said elongate channel.
9. A cap as defined in claim 1 , wherein said first alignment means comprises associated elongate alignment holes in said opposing edges; and a pin inserted into said associated elongate holes, said associated elongate holes being located to provide alignment of said elongate edges when opposing ends of said pin are inserted therein.
10. A cap as defined in claim 9 , wherein said second alignment means comprises flat strip attached across said interface parting line.
11. A cap as defined in claim 2 , wherein said second alignment means comprises a flat strip attached to at least one surface formed by said flat strip portion across said interface parting line.
12. A cap as defined in claim 10 , wherein said flat strip comprises a strip of tape.
13. A cap as defined in claim 11 , wherein said flat strip comprises a strip of tape.
14. A cap as defined in claim 1 , wherein said first alignment means comprises a wire received in coextensive alignment holes within said opposing edges.
15. A cap as defined in claim 14 , wherein said wire is flexible.
16. A cap as defined in claim 15 , wherein said wire is made of metal.
17. A cap as defined in claim 15 , wherein said wire is made of an elastomeric material.
18. A cap as defined in claim 2 , wherein said flat strip portion defines opposing generally flat surfaces, and said second alignment means comprises a tape applied to at least one of said flat surfaces.
19. A cap as defined in claim 18 , wherein tape is applied to both opposing flat surfaces.
20. A method of assembling a sliding track assembly for a cap with a rotatable brim, comprising the steps of connecting an elongate slide, attachable to a brim of the cap, to a track, attachable along the circumferential edge of a crown of the cap, the track having free ends or edges provided with associated alignment holes at the free ends or edges, in interlocking sliding relationship; configuring the track to bring the free ends or edges of the elongate track into juxtaposed abutting positions along a generally circular path; aligning the opposing free ends or edges when brought into abutment and inserting a pin or wire into said alignment holes to form a substantially continuous track with an interface parting line; and applying a tape extending across at least a portion of said interface parting line to prevent relative movements of said opposing free ends or edges about said pin or wire, whereby said free ends or edges are fixed and stabilized at the interface parting line to maintain alignment and eliminate discontinuities at said free ends or edges in the elongate track to insure smooth movements of said brim independently of the position of said brim along said elongate track.
