Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
107 words
In a vacuum cleaner having a body, nozzle means at one end of the body, and means for effecting suction of air through said nozzle, structure comprising: a dirt box removably carried by said body for receiving air from said nozzle and arranged to remove and collect dirt from the air; and a handle movably mounted on said body for selective retracted disposition overlying said dirt box for manipulating the vacuum cleaner and preventing removal of the dirt box from the body in a hand carried vacuum cleaning operation, and extended disposition for use in manipulating the vacuum cleaner in an upright floor carried vacuum cleaning operation.
Claim 2
Dependent Claim
107 words
In a vacuum cleaner having a body, nozzle means at one end of the body, and means for effecting suction of air through said nozzle, structure comprising: a dirt box removably carried by said body for receiving air from said nozzle and arranged to remove and collect dirt from the air; and a handle movably mounted on said body for selective retracted disposition overlying said dirt box for manipulating the vacuum cleaner and preventing removal of the dirt box from the body in a hand carried vacuum cleaning operation, and extended disposition for use in manipulating the vacuum cleaner in an upright floor carried vacuum cleaning operation.
Claim 3
Dependent Claim
33 words
The vacuum cleaner structure of claim 1 wherein said dirt box includes a handle for manipulation thereof independently of said body handle, said dirt box handle being substantially smaller than said body handle.
Claim 4
Dependent Claim
16 words
The vacuum cleaner structure of claim 1 wherein said handle is pivotally connected to said body.
Claim 5
Dependent Claim
30 words
The vacuum cleaner structure of claim 1 further including means for limiting the movement of said handle on said body to preselected positions corresponDing to said retracted and extended dispositions.
Claim 6
Dependent Claim
27 words
The vacuum cleaner structure of claim 1 wherein said suction means includes an electric motor and said movable handle carries wiring for controlling operation of said motor.
Claim 7
Dependent Claim
67 words
The vacuum cleaner structure of claim 1 wherein said suction means includes an electric motor and said movable handle carries wiring for controlling operation of said motor, said structure further including means for limiting the movement of said handle on said body to preselected positions corresponding to said retracted and extended dispositions preventing excessive twisting of said wiring upon movement of said handle relative to said body.
Claim 8
Dependent Claim
45 words
The vacuum cleaner structure of claim 1 wherein said suction means is disposed between said nozzle and said dirt box and said body defines means for conducting air from said nozzle to said dirt box for flow from the dirt box to said suction means.
Claim 9
Dependent Claim
21 words
The vacuum cleaner structure of claim 1 wherein said handle has a length substantially equal to the length of said body.
Claim 10
Dependent Claim
32 words
The vacuum cleaner structure of claim 1 including an upstanding support on said body, said handle being pivotally mounted to said support to be spaced from said body in said retracted disposition.
Claim 11
Dependent Claim
53 words
The vacuum cleaner structure of claim 1 including an upstanding support on said body, said handle being pivotally mounted to said support to be spaced from said body in said retracted disposition and means on said body engaged by the distal end of the handle when the handle is in said retracted disposition.
Claim 12
Dependent Claim
97 words
In a vacuum cleaner having a body, nozzle means, and air flow means, means for selectively converting the vacuum cleaner from a floor operated vacuum cleaner to a hand held vacuum cleaner comprising: handle means; and means movably connecting said handle to the vacuum cleaner body for selective positioning in a first disposition adjacent said body for manipulating the vacuum cleaner and preventing removal of the dirt box from the body in a hand carried operation, and in a second disposition extending away from the body for manipulating the vacuum cleaner in an upright floor carried operation.
Claim 13
Dependent Claim
97 words
In a vacuum cleaner having a body, nozzle means, and air flow means, means for selectively converting the vacuum cleaner from a floor operated vacuum cleaner to a hand held vacuum cleaner comprising: handle means; and means movably connecting said handle to the vacuum cleaner body for selective positioning in a first disposition adjacent said body for manipulating the vacuum cleaner and preventing removal of the dirt box from the body in a hand carried operation, and in a second disposition extending away from the body for manipulating the vacuum cleaner in an upright floor carried operation.
Claim 14
Dependent Claim
15 words
The vacuum cleaner means of claim 11 wherein said connecting means comprises pivot mounting means.
Claim 15
Dependent Claim
30 words
The vacuum cleaner means of claim 11 wherein said connecting means comprises pivot mounting means and means for limiting the maximum pivotal movement of said handle about the pivot axis.
