Abstract
An improvement in collapsible receptacles including the provision of respective inwardly and outwardly directed projections on the base frame and sidewalls of the receptacle. The outwardly directed projection of the sidewall overlaps the inwardly directed projection of the base frame to maintain the receptacle in the assembled non-collapsed condition such that a tilting of the sidewalls is necessary to raise the sidewall. The overlapping projection on the sidewall also serves as a water shield for the joint between the frame and sidewalls.
Claims21
Collapsible receptacle comprising:
- a base frame having a plurality of vertically extending oblong holes,
- a plurality of sidewalls having hinge bolts connected to the lower ends thereof, said hinge bolts being positioned in said oblong holes in the assembled condition of the receptacle,
- said oblong holes being longer than the cross-sectional size of said hinge bolts and having an opening adjacent their upper ends for introducing the hinge bolts,
- and blocking means for preventing the removal of the hinge bolts from the respective oblong holes during normal use of the receptacle,
- wherein each sidewall has a first outwardly directed projection and wherein said base frame has a plurality of inwardly directed projections corresponding in number to the number of walls, and wherein said first outwardly directed projections overlap corresponding ones of said inwardly directed projections when the receptacle is in an assembled and non-collapsed condition, said overlapping projections serving to maintain the receptacle in said non-collapsed condition.
2 more elements
A collapsible receptacle comprising:
- at least one base frame means,
- and at least one sidewall means slidably connected to said frame means between a collapsed position and an assembled position,
- wherein each sidewall means has a first outwardly directed projection means and a second outwardly directed projection means, said base frame means has at least one inwardly directed projection means, said outwardly directed projection means engages beneath at least a corresponding one of said inwardly directed projection means of said base frame means to prevent raising of said sidewall means except in an inclined position, said first outwardly directed projection means overlaps at least a corresponding one of said inwardly directed projection means when the receptacle is in an assembled and non-collapsed condition, said overlapping inwardly and outwardly directed projection means serving to maintain the receptacle in said non-collapsed condition.
A collapsible receptacle comprising:
- at least one base frame means,
- and at least one sidewall means slidably connected to said base frame means between a collapsed position and an assembled position,
- wherein each sidewall means has at least a first outwardly directed projection means constructed as water guide means for directing rainwater and the like outwards of the receptacle and wherein said base frame means has at least one inwardly directed projection means, said at least a first outwardly directed projection means overlaps at least a corresponding one of said at least one inwardly directed projection means when the receptacle is in an assembled and non-collapsed condition, said overlapping inwardly and outwardly directed projection means serving to maintain the receptacle in said non-collapsed condition.
A collapsible receptacle comprising:
- at least one base frame means,
- and at least one sidewall means slidably connected to said base frame means between a collapsed position and an assembled position,
- wherein said base frame means has a plurality of oblong holes in which said sidewall means is slidably connected, each sidewall means has at least a first outwardly directed projection means and said base frame means has at least one inwardly directed projection means, said at least a first outwardly directed projection means overlaps at least a corresponding one of said at least one inwardly directed projection means when the receptacle is in an assembled and non-collapsed condition, said overlapping inwardly and outwardly directed projection means serving to maintain the receptacle in said non-collapsed condition.
