Description




FIELD OF THE INVENTION




This invention pertains to collapsible hampers that may be compactly stored or transported in a collapsed state and deployed into a usable assembled hamper. Particularly, the hamper is easily assembled and disassembled as required by the end user.




BACKGROUND OF THE INVENTION




Hampers that are typically used to store and/or transport laundry or other lightweight articles and are stored and shipped fully assembled and ready for use. The bulkiness and size of many of these hampers increases the shipping costs of such items and presents shelf space and storage problems for merchants. However, to be of use, laundry hampers must be large enough in size to hold a reasonable amount of dirty clothing.




Hampers are available in a great variety of types and designs. Hampers have typically been constructed of wicker or plastic. Such hampers may have a top closure or cover that is hinged to the container and serves to shut the container when it is not in use. Another type of hamper consists of a fabric bag that is supported upon a frame or stand.




Some hampers have been shipped in parts requiring assembly by the merchant upon arrival or by the consumer upon purchase. These collapsible baskets and containers have typically included a variety of pre-shaped components that require alignment and fastening that is difficult, tedious and may require a variety of tools.




Accordingly, there is a need for a laundry hamper that can be conveniently shipped, transported, stored and that can be quickly and easily assembled for use.




SUMMARY OF THE INVENTION




The invention provides a knockdown, or collapsible, hamper. The hamper has a frame that includes two generally U-shaped supports defining a bottom portion and upstanding members. The bottom portion has cross-members that rotate about a pivot point and the upstanding members extend obliquely from the bottom portion, and form the generally vertical, upstanding members of the frame. A plurality of rings slide over the bottom portion and along the upstanding members and are received in notches formed in the upstanding members to create a generally conical shape with the bottom portion and upstanding members of the frame.




In one embodiment, the collapsible hamper includes a frame that is formed from two generally U-shaped supports. The generally flat bottom portions of the U-shaped supports are connected near the center of each bottom portion and, by a scissors-type movement, the supports can pivot from a generally flat cross-section to a maximum cross-section in which the two bottom generally cross perpendicularly. The upstanding members of the U-shaped supports have notches formed therein that are spaced apart from one another. The notches on each of the upstanding members correspond with the notches on the other upstanding members and align horizontally. A plurality of rings of varying circumferences perpendicularly align with the upstanding members and click or snap or are set securely into the notches. The frame and rings form a generally conical shaped structure. A bag is fitted into the conical shaped structure providing a hamper ready for use.




Other objects and advantages of the invention, as well as additional inventive features, will be apparent from the description of the invention provided herein and in the associated figures and appended claims.

DETAILED DESCRIPTION OF THE INVENTION




A collapsible hamper


10


embodying the present invention is illustrated in

FIGS. 1-4

and includes a frame


15


comprised of two generally U-shaped supports


20


. The two U-shaped supports


20


include upstanding members


22


and bottom portions


24


. The bottom portions


24


are fastened together, for example, by machine screw


25


and cap nut. The fastening of the bottom portions


24


of the U-shaped supports


20


is such that the bottom portions


24


may pivot within a range of a minimum cross-section at which point the bottom portions


24


approach a parallel arrangement with one another and, on the opposite extreme of the range, a perpendicular orientation in which the bottom portions


24


intersect in a substantially perpendicular arrangement. The Figures depict a double ring


26


with tabs


28


. The tabs


28


are aligned with tabs


30


of upstanding members


22


of the U-shaped supports


20


when the bottom portions


24


are oriented generally perpendicular to one another.




Referring to

FIGS. 1-4

, a series of rings


32


,


34


,


36


are affixed to the upstanding members


22


of the U-shaped supports


20


. The rings


32


,


34


,


36


are aligned generally perpendicular to the upstanding members


22


of the U-shaped supports


20


and are received into notches


40


formed into the upstanding members


22


. When the rings


32


,


34


,


36


are received in the notches


40


of the upstanding members


22


of the U-shaped support


20


, the U-shaped support


20


and rings


32


,


34


,


36


form a generally conical-shaped structure. The notches


40


are formed into a length of the upstanding members


22


at intervals that correspond to the intervals between the notches


40


of the each other upstanding member


22


. The frame


15


, double ring


26


and rings


32


,


34


,


36


are preferably stainless steel or aluminum wire or tubing, but may be drawn or cast from any suitable metal or alloy.




The circumference of each of the rings


32


,


34


,


36


corresponds to a circumference of a cross-section of the hamper


10


where the rings


32


,


34


,


36


will be received along the conical shape. The notches


40


are placed and shaped to allow the rings


32


,


34


,


36


to click or snap in place and to maintain their position during use of the hamper


10


. In order for the rings


32


,


34


,


36


to maintain their position in the notches


40


, the rings


32


,


34


,


36


may temporarily deform the upstanding members

32


,


34


,


36


in the order of largest


32


, then middle


34


and then smallest


36


according to circumference. The largest ring


32


is placed over the bottom portions


24


of the frame


15


and moved along the upstanding members


22


of the frame


15


toward the double ring


26


. Travel of the largest ring


32


continues along the upstanding members


22


of the frame


15


until the circumference of the largest ring


32


is contacted by each the upstanding members


22


in a generally perpendicular orientation to the plane of the ring


32


. The consumer will then set, snap or click the ring


32


into one of a plurality of notches


40


on each upstanding member


22


that has been formed for the purpose of receiving the ring


32


.




Assembly of the hamper continues by placement of the middle ring


34


and then the smallest ring


36


in the same manner as the largest ring


32


was placed. Casters


42


are then optionally placed in mounting sleeves


44


affixed to the bottom portions


24


of the frame


15


. The structure is then returned to an upright position from the inverted position. A bag


46


is fitted into the frame


15


and over handles


48


of the double ring


26


. The hamper


10


is then complete and ready for use. The hamper
