Abstract
Abstract A release mechanism for use with vacuum cleaning appliances having a pipe and hose arrangement, where the pipe is slidably mounted inside the hose. The release mechanism comprises an inner sleeve, an outer sleeve and actuating buttons. The inner sleeve couples the pipe to the hose. By using the actuating buttons, the inner sleeve is operational in a closed position and an open position. In the closed position, the pipe can slide inside the hose, but it cannot be removed or detached from the hose. In the open position, the pipe can be removed or detached from the hose. The outer sleeve secures the release mechanism to the hose and houses the inner sleeve and actuating buttons.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
92 words
A device for coupling a pipe slidably mounted inside a hose, said device comprising: (a) means for retaining the pipe inside the hose; and (b) means for coupling said retaining means to one end of the hose; (c) said means for retaining having actuating means for pivotally moving said retaining means between an open position and a closed position, in said closed position said retaining means preventing the pipe from being removed from the hose, and in said open position said retaining means allowing the pipe to be removed from the hose.
Claim 2
Independent Claim
92 words
A device for coupling a pipe slidably mounted inside a hose, said device comprising: (a) means for retaining the pipe inside the hose; and (b) means for coupling said retaining means to one end of the hose; (c) said means for retaining having actuating means for pivotally moving said retaining means between an open position and a closed position, in said closed position said retaining means preventing the pipe from being removed from the hose, and in said open position said retaining means allowing the pipe to be removed from the hose.
Claim 3
Dependent Claim
41 words
The device as claimed in claim 1, wherein said means for retaining comprises an inner sleeve, in said closed position said inner sleeve surrounds the pipe and forms a stopping edge which prevents the pipe from being removed from the hose.
Claim 4
Dependent Claim
91 words
The device as claimed in claim 2, wherein said inner sleeve comprises first and second half sections, said first and second half sections having positioning means for mating said first and second half sections to form a substantially cylindrical shape having said stopping edge formed at one end when in said closed position, and said first and second half sections including pivotal coupling means and said actuating means being coupled to said pivotal coupling means so that said inner sleeve can operate in the closed position and in the open position.
Claim 5
Dependent Claim
36 words
The device as claimed in claim 3, wherein said means for retaining includes means for biasing said retaining means in the closed position, said means for biasing being coupled to said first and second half sections.
Claim 6
Dependent Claim
60 words
The device as claimed in claim 4, wherein said actuating means comprises first and second actuator members, said actuator members being connected to the end of said first and second half sections opposite the end having said stopping edge and said actuating members operating in cooperation with said pivotal coupling means to move said inner sleeve into said open position.
Claim 7
Dependent Claim
44 words
The device as claimed in claim 5, wherein said means for coupling comprises a cuff, said cuff including means for attaching to one end of the hose and receiving said means for coupling so that said coupling means are secured to the flexible hose.
Claim 8
Dependent Claim
28 words
The device as claimed in claim 6, wherein said means for biasing comprises a tension ring positioned on the end of said inner sleeve having said stopping edge.
Claim 9
Independent Claim
178 words
A device for coupling a pipe slidably mounted inside a hose for use with a vacuum cleaning appliance, said device comprising: (a) an inner sleeve, said inner sleeve having a recess for slidably accepting the pipe; (b) said inner sleeve comprising first and second sections, said first and second sections including positioning means for mating said first and second sections to form a substantially cylindrical shape; (c) said positioning means including means for providing a pivotal coupling between said first and second sections and allowing said inner sleeve to move between an open position and a closed position; (d) means for biasing said first and second sections in the closed position; (e) actuating means for moving said inner sleeve to the open position, said actuating means including first and second actuator members, said first actuator member being connected to said first section and said second actuator member being connected to said second section of said inner sleeve; and (f) a cuff, said cuff including means for attaching to the hose and means for attaching to said inner sleeve.
Claim 10
Independent Claim
178 words
A device for coupling a pipe slidably mounted inside a hose for use with a vacuum cleaning appliance, said device comprising: (a) an inner sleeve, said inner sleeve having a recess for slidably accepting the pipe; (b) said inner sleeve comprising first and second sections, said first and second sections including positioning means for mating said first and second sections to form a substantially cylindrical shape; (c) said positioning means including means for providing a pivotal coupling between said first and second sections and allowing said inner sleeve to move between an open position and a closed position; (d) means for biasing said first and second sections in the closed position; (e) actuating means for moving said inner sleeve to the open position, said actuating means including first and second actuator members, said first actuator member being connected to said first section and said second actuator member being connected to said second section of said inner sleeve; and (f) a cuff, said cuff including means for attaching to the hose and means for attaching to said inner sleeve.
Claim 11
Dependent Claim
33 words
The device as claimed in claim 8, wherein said actuating members each include a button for receiving a manually applied force and moving said inner sleeve to the open position in response thereto.
