Abstract

Abstract An improved trash receptacle is provided according to this invention. The invention is particularly directed to trash containers of the type having a top assembly having a frame and a pivoting door which encloses a central opening of the frame. The improvement comprises a pivot means for the door including a pivot member and a socket which enable the door to be retained in its normal position by gravity, but which permits the door to be easily detached from the frame to enable it to be inserted into the trash container to compress material therein. Once the user has completed the compaction step, the door is re-engaged with the frame.

Claims Analysis

Total Claims: 11
Claim 1
Independent Claim 161 words
An improved top assembly for a trash receptacle of the type having a frame attachable to the open perimeter of a container, said frame having a central opening, said top assembly further having a door for opening or closing said central opening attached to said frame for pivoting movement, said top assembly comprising: pivot means for mounting said door to said frame including a pivot member having a generally convex surface which is received by a socket having a generally concave surface, said pivot member and said socket being retained by gravity in a normal usage condition which enables said door to be pivoted between closed and opened positions, said pivot member and said socket enabling said door to be lifted, thereby disengaging said pivot member from said socket whereby said door can be inserted through said central aperture to compress material in said container, and handle means formed by said door enabling said door to be grasped by a user.
Claim 2
Dependent Claim 161 words
An improved top assembly for a trash receptacle of the type having a frame attachable to the open perimeter of a container, said frame having a central opening, said top assembly further having a door for opening or closing said central opening attached to said frame for pivoting movement, said top assembly comprising: pivot means for mounting said door to said frame including a pivot member having a generally convex surface which is received by a socket having a generally concave surface, said pivot member and said socket being retained by gravity in a normal usage condition which enables said door to be pivoted between closed and opened positions, said pivot member and said socket enabling said door to be lifted, thereby disengaging said pivot member from said socket whereby said door can be inserted through said central aperture to compress material in said container, and handle means formed by said door enabling said door to be grasped by a user.
Claim 3
Dependent Claim 21 words
The improved top assembly according to claim 1 wherein said door defines said pivot member and said frame defines said socket.
Claim 4
Dependent Claim 34 words
The improved top assembly according to claim 1 wherein a first stop means is positioned on said frame for limiting rotational movement of said door and for supporting said door in said closed position.
Claim 5
Dependent Claim 31 words
The improved top assembly according to claim 3 wherein said door has a means for urging said door to remain in said closed position and supported by said first stop means.
Claim 6
Dependent Claim 51 words
The improved top assembly according to claim 4 wherein said means for urging said door comprises said door having a center of gravity displaced from the axis of rotation of said door defined by said pivot means such that said door is urged to remain in said closed position by gravity.
Claim 7
Dependent Claim 27 words
The improved top assembly according to claim 3 wherein said first stop means is defined by ledges connected to said frame and extending into said central opening.
Claim 8
Dependent Claim 35 words
The improved top assembly according to claim 3 further comprising second stop means for limiting the extent of angular travel of said door about said pivot means from said closed position to said opened position.
Claim 9
Dependent Claim 47 words
The improved top assembly according to claim 7 wherein said second stop means comprises at least one projection extending from said frame adjacent said socket and positioned to come into contact with said door when said door is moved from said closed position to said opened position.
Claim 10
Dependent Claim 34 words
The improved top assembly according to claim 3 wherein said first stop means is defined by a lip connected to said door and abutting said frame when said door is in said closed position.
Claim 11
Dependent Claim 65 words
The improved top assembly according to claim 1, wherein said handle means comprises a handle member and a cup portion partially surrounding said handle member thereby defining a channel formed between said cup portion and said handle member for providing access for a user's hand around said handle member and for protecting the user from contacting trash material when said door is compressing waste material.
