Abstract
Abstract A cord winder arrangement particularly for a vacuum cleaner or other household appliance in which the vacuum cleaner housing is provided with a section having a closable access door through which the cord and the electrical connection plug passes through when the vacuum cleaner is inoperative, thereby enclosing the electrical cord and its plug entirely within the vacuum cleaner housing. The access door is operated by a foot button that opens the door and, at the same time, projects the plug out of the housing when it is desired to operate the appliance.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
122 words
A cord winding structure for a vacuum cleaner or other household appliance comprising a housing having a cord winder mechanism therein, the free end of the electrical cord having a connection plug for insertion in an electrical outlet, a free space in said housing adjacent to said cord winder mechanism capable of receiving and storing the connection plug and that portion of the electrical cord connected therewith and adjacent thereto, a foot or manual operator projecting from said housing, and a follower plate operatively connected to said operator and arranged to move said connection plug from said space inside said housing to a position at least partially outside of said housing when said operator is actuated thereby making said plug easily accessible.
Claim 2
Dependent Claim
122 words
A cord winding structure for a vacuum cleaner or other household appliance comprising a housing having a cord winder mechanism therein, the free end of the electrical cord having a connection plug for insertion in an electrical outlet, a free space in said housing adjacent to said cord winder mechanism capable of receiving and storing the connection plug and that portion of the electrical cord connected therewith and adjacent thereto, a foot or manual operator projecting from said housing, and a follower plate operatively connected to said operator and arranged to move said connection plug from said space inside said housing to a position at least partially outside of said housing when said operator is actuated thereby making said plug easily accessible.
Claim 3
Dependent Claim
50 words
The cord winding structure as claimed in claim 1 wherein said space has an opening, a pivotable lid at least partly covering said opening when said cord is wound on said reel, and means linking said operator and said follower plate which opens said lid when said operator is actuated.
Claim 4
Dependent Claim
22 words
The cord winding structure as claimed in claim 2 wherein said operator is push button that is operated externally of said housing.
Claim 5
Dependent Claim
16 words
The cord winding structure as claimed in claim 2 wherein linking means is an L-shaped arm.
Claim 6
Dependent Claim
22 words
The cord winding structure as claimed in claim 2 further comprising a brake device for said cord being connected to said lid.
Claim 7
Dependent Claim
47 words
The cord winding structure as claimed in claim 5 wherein said brake device is provided with one part that is stationary relative to said lid and another spaced part which is eccentric and rotatable relative to said lid, said cord passing through said space between said parts.
Claim 8
Dependent Claim
50 words
The cord winding structure as claimed in claim 6 further comprising a swingable arm having one end pivotally attached to said rotatable part, the other end of said swingable arm being provided with a hook which adapted to engage a portion of said housing when said brake device is inoperative.
Claim 9
Dependent Claim
49 words
The cord winding structure as claimed in claim 7 further comprising a shaft mounting said rotatable part, and two spaced arms projecting from said stationary part, said shaft extending between said two arms and together with said stationary part and said rotatable part forms a guide surrounding said cord.
