Abstract
Abstract A chute is disclosed for passing articles such as laundry between floors or walls in a building. The chute has a tubular frame to be securely inserted in an opening in a planar partition, and a flexible tube attached to and hanging from the frame. The tubular frame has a peripheral wall defining an inlet in communication with one side of the planar partition and an outlet extending beyond the other side of the planar partition. A peripheral flange is outwardly directed from the peripheral wall adjacent to the inlet and is adapted to rest against one side of the planar partition. A gripping projection extends transversely from the peripheral wall and is spaced from the other side of the planar partition. The flexible tube is releasably attached to the gripping projection. A lid is movably connected to the frame to open and close the inlet.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
182 words
A chute for use in an opening in a planar partition, comprising: a tubular frame, adapted to be securely inserted into said opening, having a peripheral wall defining an inlet in communication with one side of the partition, and an outlet extending from the other side of the partition; a peripheral flange outwardly directed from said peripheral wall adjacent to said inlet, said flange contacting said partition to prevent said frame from passing through the partition; a gripping projection extending transversely around said peripheral wall and spaced from said partition other side; a flexible tube having an open end portion adapted to be slid onto said frame over said gripping projection; attaching means located on said flexible tube end portion for bringing said flexible tube end portion into engagement with said gripping projection to releasably attach the tube to the frame, said attaching means being a sleeve formed in the open end portion of said tube and a flexible attaching member threaded therethrough; and planar closure means, movably connected to said frame proximate said inlet, for selectively covering and exposing said inlet.
Claim 2
Dependent Claim
182 words
A chute for use in an opening in a planar partition, comprising: a tubular frame, adapted to be securely inserted into said opening, having a peripheral wall defining an inlet in communication with one side of the partition, and an outlet extending from the other side of the partition; a peripheral flange outwardly directed from said peripheral wall adjacent to said inlet, said flange contacting said partition to prevent said frame from passing through the partition; a gripping projection extending transversely around said peripheral wall and spaced from said partition other side; a flexible tube having an open end portion adapted to be slid onto said frame over said gripping projection; attaching means located on said flexible tube end portion for bringing said flexible tube end portion into engagement with said gripping projection to releasably attach the tube to the frame, said attaching means being a sleeve formed in the open end portion of said tube and a flexible attaching member threaded therethrough; and planar closure means, movably connected to said frame proximate said inlet, for selectively covering and exposing said inlet.
Claim 3
Dependent Claim
29 words
A chute as claimed in claim 1 wherein said gripping projection is in the form of a peripheral flange extending outwardly from said peripheral wall adjacent to said outlet.
Claim 4
Dependent Claim
57 words
A chute according to claim 2 wherein said flexible attaching member is a draw string for constricting the open end portion of the said tube when tightened, said draw string being adapted to be located between said peripheral flange and said partition to prevent the open end portion of the tube from sliding off the tubular frame.
Claim 5
Dependent Claim
55 words
A chute according to claim 2 wherein said flexible attaching member is an elastic member for constricting the open end portion of the said tube, said elastic member being adapted to be located between said peripheral flange and said partition to prevent the open end portion of the tube from sliding off the tubular frame.
Claim 6
Dependent Claim
43 words
A chute as claimed in claim 1 wherein said gripping projection is a protrusion having an upper wall, an inside wall and a lower wall, said protrusion extending inwardly from said peripheral wall to form an inwardly disposed peripheral groove in said wall.
Claim 7
Dependent Claim
53 words
A chute according to claim 5 wherein said flexible attaching member is a draw string for constricting the open end portion of the said tube when tightened, said draw string being adapted to be located in said groove to prevent the open end portion of the tube from sliding off the tubular frame.
Claim 8
Dependent Claim
50 words
A chute according to claim 5 wherein said flexible attaching member is an elastic member for constricting the open end portion of the tube, said elastic member being adapted to be located in said groove to prevent the open end portion of the tube from sliding off the tubular frame.
Claim 9
Dependent Claim
27 words
A chute according to claim 1, wherein said closure means has stop means for restricting movement thereof and preventing said closure means from reaching a vertical position.
Claim 10
Dependent Claim
50 words
A chute according to claim 8 wherein said closure means has an outwardly facing face, and further comprising a handle movably connected to said closure means, said closure means further comprising means for seating said handle in a generally flush relationship with said outward facing face of said closure means.
Claim 11
Dependent Claim
50 words
A chute according to claim 1 wherein said closure means has an outwardly facing face, and further comprising a handle movably connected to said closure means, wherein said closure means is profiled to seat said handle in a generally flush relationship with said outward facing face of said closure means.
Claim 12
Dependent Claim
42 words
A chute according to claim 1 wherein said closure means is hingeably connected to said peripheral wall and wherein said frame has means for holding said closure means flush with said flange when said closure means is moved to cover said inlet.

A chute according to claim 1 wherein said tube is sufficiently flexible that it may be packed into said frame.
Claim 14
Dependent Claim
20 words
A chute according to claim 8 wherein said tube is sufficiently flexible that it may be packed into said frame.
Claim 15
Dependent Claim
64 words
A chute according to claim 11 wherein said closure means has an outwardly facing face, wherein said tube is sufficiently flexible that it may be packed into said frame, and further comprising a handle movably connected to said closure means, wherein said closure means is profiled to seat said handle in a generally flush relationship with said outward facing face of said closure means.
