Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
136 words
In an upright vacuum cleaner having a handle extending from a main body portion of said cleaner, a fill tube in confluent communication with a dirt collecting bag and a dirt cup holder from which a dirt cup depends, the improvement including: a lateral extent on said dirt cup holder and a tubular portion extending downwardly from said lateral extent, said lateral extent surrounding said handle and said tubular portion extending telescopically over it so that said dirt cup holder can move freely up and down said handle, said dirt collecting bag having lower reaches adjacent to and attached to said dirt cup holder, said handle being pivoted to said main body portion of said cleaner, and said dirt cup holder telescopically moving along said handle as said handle pivots relative to said main body portion.
Claim 2
Dependent Claim
136 words
In an upright vacuum cleaner having a handle extending from a main body portion of said cleaner, a fill tube in confluent communication with a dirt collecting bag and a dirt cup holder from which a dirt cup depends, the improvement including: a lateral extent on said dirt cup holder and a tubular portion extending downwardly from said lateral extent, said lateral extent surrounding said handle and said tubular portion extending telescopically over it so that said dirt cup holder can move freely up and down said handle, said dirt collecting bag having lower reaches adjacent to and attached to said dirt cup holder, said handle being pivoted to said main body portion of said cleaner, and said dirt cup holder telescopically moving along said handle as said handle pivots relative to said main body portion.
Claim 3
Dependent Claim
68 words
The cleaner set forth in claim 1 wherein: a flexible bellows-like element is attached to and extends from said main body portion and is connected to said fill tube, said fill tube being attached to said dirt cup holder whereby extension and compression of said bellow-like element during pivoting of said handle moves said dirt cup holder telescopically along said handle relieving strains imposed on said bellows-like element.
Claim 4
Dependent Claim
83 words
The cleaner of either claims 1 or 2 wherein: a latch arrangement is additionally provided said latch arrangement including at least one resilient latching element, said resilient latching element extending downwardly along said dirt cup from said dirt cup holder and including a nose portion at its lower end that engages a bottom side of said dirt cup to captivate said dirt cup with said dirt cup holder, said resilient latching element being deformable intermediate its ends for release of said dirt cup.
Claim 5
Dependent Claim
57 words
The cleaner as set out in claim 1 wherein: said tubular portion of said dirt cup holder includes an oblong bore with curved portions, in cross section, for said telescopic engagement of said tubular portion over said handle to thereby enable the use of one of a round and square handle to mount said dirt cup holder.
Claim 6
Dependent Claim
37 words
The cleaner set out in claim 1 wherein: said dirt cup holder includes at least one downwardly disposed plate-like member extending from said lateral extent, said plate-like member being attached at its bottom to said fill tube.
Claim 7
Dependent Claim
159 words
In an upright vacuum cleaner having a handle extending from a main body portion of said cleaner, a fill tube in confluent communication with a dirt collecting bag and a dirt cup holder from which a dirt cup depends, the improvement including: a lateral extent on said dirt cup holder and a tubular portion extending downwardly from said lateral extent, said lateral extent surrounding said handle and said tubular portion extending telescopically over it so that said dirt cup holder can move freely up and down said handle, said dirt collecting bag having lower reaches adjacent to and attached to said dirt cup holder, said dirt collecting bag including at its lower reaches a hooped reinforcing member, a bag expander, an upper portion of said dirt cup holder and said bag expander having complementary hook and a loop portions and said hooped reinforcing member being caught between said bag expander and said upper portion of said dirt cup holder.
Claim 8
Dependent Claim
159 words
In an upright vacuum cleaner having a handle extending from a main body portion of said cleaner, a fill tube in confluent communication with a dirt collecting bag and a dirt cup holder from which a dirt cup depends, the improvement including: a lateral extent on said dirt cup holder and a tubular portion extending downwardly from said lateral extent, said lateral extent surrounding said handle and said tubular portion extending telescopically over it so that said dirt cup holder can move freely up and down said handle, said dirt collecting bag having lower reaches adjacent to and attached to said dirt cup holder, said dirt collecting bag including at its lower reaches a hooped reinforcing member, a bag expander, an upper portion of said dirt cup holder and said bag expander having complementary hook and a loop portions and said hooped reinforcing member being caught between said bag expander and said upper portion of said dirt cup holder.
