Abstract
Abstract A reel body rotatably supported on a frame and spring-urged into a given reference position includes a main peripheral cord storage compartment having an axial and radial extent each equal to a number of cord thicknesses, a cord take-up compartment positioned alongside said main cord storage compartment and having an axial extent of only about one cord thickness. The main cord storage and cord take-up compartments respectively having hub portions around which different portions of the same cord are wound initially in the same direction, the ub portion of the main cord storage compartment being positioned substantially outwardly of the hub portion of the cord take-up compartment. The cord wound around the hub portion of the main cord storage compartment has an inner winding connected to the first or inner winding on the hub portion of the cord take-up compartment which joins a number of windings which is only a fraction of the number of windings in the main cord storage compartment.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
298 words
A retractable cord reel assembly comprising: a casing have side and opposite end walls forming an enclosure; a reel body rotatably supported in said casing enclosure for rotation about an axis extending transversely of said casing end walls; spring means for urging said reel body toward an initial position, the spring means tensing as the reel body rotates from said initial position; said reel body including contiguous axially spaced concentric outer and inner hub portions positioned respectively relatively far from and relatively close to said axis of rotation of the reel body, first and second axially spaced wall means extending radially from said outer hub portion to form therebetween a main cord storage compartment having an axial and radial extent each equal to a number of cord thicknesses, and third wall means extending radially from said inner hub portion but axially spaced from one of said first and second wall means to define therebetween a cord take-up compartment having an axial extent of about one cord thickness, said third wall means fitting into an opening in one of said casing end walls so as to be in substantially planar alignment therewith; and a cord with the major portion of its length wound around said outer hub portion of the reel body so that the winding thereof from the reel body will tense said spring means, the inner end of the cord in said main cord storage compartment extending first to said second hub portion of said cord take-up compartment and winding in said cord take-up compartment in the same direction as the cord is wound in said main cord storage compartment, the number of windings of the cord in said cord take-up compartment being only a fraction of the number of windings in said main cord storage compartment.
Claim 2
Dependent Claim
298 words
A retractable cord reel assembly comprising: a casing have side and opposite end walls forming an enclosure; a reel body rotatably supported in said casing enclosure for rotation about an axis extending transversely of said casing end walls; spring means for urging said reel body toward an initial position, the spring means tensing as the reel body rotates from said initial position; said reel body including contiguous axially spaced concentric outer and inner hub portions positioned respectively relatively far from and relatively close to said axis of rotation of the reel body, first and second axially spaced wall means extending radially from said outer hub portion to form therebetween a main cord storage compartment having an axial and radial extent each equal to a number of cord thicknesses, and third wall means extending radially from said inner hub portion but axially spaced from one of said first and second wall means to define therebetween a cord take-up compartment having an axial extent of about one cord thickness, said third wall means fitting into an opening in one of said casing end walls so as to be in substantially planar alignment therewith; and a cord with the major portion of its length wound around said outer hub portion of the reel body so that the winding thereof from the reel body will tense said spring means, the inner end of the cord in said main cord storage compartment extending first to said second hub portion of said cord take-up compartment and winding in said cord take-up compartment in the same direction as the cord is wound in said main cord storage compartment, the number of windings of the cord in said cord take-up compartment being only a fraction of the number of windings in said main cord storage compartment.
Claim 3
Dependent Claim
285 words
The retractable cord reel assembly of claim 1 wherein said reel body is an assembly of a first reel body member having a radially extending end wall portion forming said first wall means and an annular wall extending axially from one side of said end wall portion to define part of said outer hub portion of the reel body, the radially inwardly facing side of said annular wall forming the outer margins of a spiral leaf spring-receiving compartment, a second reel body member having a radially extending end wall portion forming said second wall means, said second reel body member having an annular wall extending axially inwardly from the side thereof facing said first reel body member and forming another part of said outer hub portion of the reel body and having an outer surface in alignment with the outer surface of said latter annular wall to complete the outer hub portion said second reel body member having a hub portion on the outer side thereof forming said inner hub portion of the reel body which hub portion has a generally radially extending open-ended passageway extending therethrough whiCh communicates at one end thereof through an opening in the annular wall of said second reel body member with said main cord storage compartment, the other end of said radial passageway opening onto said cord take-up compartment and means securing together said first and second reel body members to form an integral rotatable assembly; said spring means being a spiral coil spring in said coil-spring receiving compartment of the reel body assembly which coil spring is anchored at one end to said reel body assembly and at the other end to a stationary portion of said frame.
Claim 4
Dependent Claim
46 words
The cord reel assembly of claim 2 wherein there is provided an end wall member sandwiched between said annular walls of said first and second reel body members to form a closure at the end of the leaf spring-receiving compartment adjacent said second reel body member.
Claim 5
Dependent Claim
26 words
The cord reel assembly of claim 2 wherein said second reel body member has attached thereto an outer end wall member forming said third wall means.
Claim 6
Dependent Claim
79 words
The cord reel assembly of claim 4 wherein said frame forms a casing for the cord reel assembly which casing has opposite end walls between which transversely extends the axis of rotation of said reel body assembly, said end wall of the casing nearest said end wall member forming the outermost side margin of said cord take-up compartment being an annular end wall having an opening therein within which fits said end wall member of the reel body assembly.
Claim 7
Dependent Claim
57 words
The cord reel assembly of claim 5 wherein said casing comprises two axially spaced casing parts, one of said casing parts has a hub projecting therefrom around which said reel body assembly is rotatably mounted, and the other casing part being removably attached to said former casing part and exposing the reel body assembly when disengaged therefrom.
Claim 8
Dependent Claim
29 words
The cord reel assembly of claim 2 wherein said frame has a stationary central hub around which portions of said first and second reel body members are rotatably supported.
