The present invention relates to the field of linen hampers. Such hampers often have a foot pedal which when pressed, lifts the lid on the hamper. When the users foot is removed, the lid closes, often with a bang. One company has a large solid walled, heavy clothes hamper which includes a damper cause the lid to close more slowly when the user's foot is removed.
The clothes hamper of the present invention comprises a lid connected to a foot pedal by at least one adjustable control rod. A cylinder closer is connected between the hamper and either the lid or the foot pedal, and in one control rod adjustment state, is biased to close the lid slowly and quietly when the foot pedal is released. However, the control rod can be adjusted such that when the foot pedal is fully depressed, the lid assumes an open position from which the cylinder will not close the lid when the foot pedal is released. The user taps the lid in a closing direction, and the cylinder will then slowly close the lid.
These and other objects, advantages and features of the invention will be more fully understood and appreciated by reference to the appended drawings and the Description of the Preferred Embodiments.
The hamper 1 of the preferred embodiment comprises a frame 10, a lid 20, a foot pedal 30, control rods 40, a closing cylinder 50, and a hamper bag 60 which can be removably mounted on frame 10 (see
The various components of the preferred embodiment are set forth and numbered in the parts list below:
Frame 10 is a lightweight tubular frame, preferably made of aluminum tubing or other lightweight material (
Legs 11 and 12 are joined towards their bottom ends by a bottom bag support frame 16. Bottom bag support frame 16 not only provides structure for cart 1 through its connection to rear legs and front legs 11 and 12, but also provides a support for a hamper bag when it is removably hung on cart 1.
A hamper bag retainer frame 14 sits on the top of top frame 13. Frame 14 is pivotally mounted on a retainer frame pivot axle 15, which in turn is fastened loosely to top frame 13, such that bag retainer frame 14 can not only be pivoted upwardly, but also can be lifted somewhat along its rear, to facilitate mounting a hamper bag on cart 1. Casters 17 are secured in the bottom of tubular legs 11 and 12 such that hamper 1 can be conveniently moved about.
Hamper lid 20 includes a pair of side flanges 21 projecting downwardly from each side at the rear of lid 20 (
Foot pedal 30 preferably comprises a generally U-shaped tubular frame member having side legs 31 and a front cross member 32. A pedal axle 33 extends between rear legs 11 near the bottoms thereof. Axle 33 passes through the end portions of the side legs 31 of pedal 30 such that pedal 30 can be pivoted up and down on pivot axle 33. Pivot axle 33 is positioned slightly below bottom bag support frame 16, and the front of foot pedal 30 extends out beyond the front of bottom bag support frame 16 for easy access. The front cross member 32 of foot pedal 30 is covered by a rubber or plastic sleeve 34 which provides a protective cushion on which the user can place his or her foot to depress foot pedal 30.
Closing cylinder 50 is connected at one end to foot pedal 30 at a pivot point a few inches forward of foot pedal pivot axle 33. Control rod 40 is bent at its point of connection to foot pedal 30, whereby it includes an extension which passes through foot pedal leg 31. Cylinder 50 is pivotally connected to said extension of said control rod 41, thereby being pivotally connected to foot pedal 30. At its other end, closing cylinder 50 is connected to a rear leg 11 of frame 10. Closing cylinder 50 is biased to the closing position, and thus tends to pull foot pedal 30 upwardly when a user releases his or her foot from foot pedal 30.
Foot pedal 30 is connected to the side flanges 21 of lid 20 by two control rods 40, one on one side and one on the other side of foot pedal 30 and lid 20. Because of this connection, depression of foot pedal 30 tends to pull lid 20 open as shown in
Connector pin 42 is held in place by a connector pin latch 43, which includes a leg 43a and a generally U-shaped clip 43b which clips over the outside of threaded sleeve 41a of connector 41, thereby holding pin 42 in place. If a user wants to adjust the length of control rod 40, he or she simply unclips connector pin latch 43, removes pin 42, and removes connector 41 from its embracing relationship with top side flange 21, thereby allowing the user to thread connector 41 upwardly or downwardly on the threaded end 40a of control rod 40. In this way, the user changes the length of control rod 40.
Control rod 40 is connected to its respective lid side flange 21 a short distance behind the pivot axle 22 for lid 20. In this manner, depression of foot pedal 30 pulls downwardly on the rear of side flange 21, causing lid 20 to pivot up on pivot axle 22 to an open position as shown for example in
By shortening the length of control rod 40 sufficiently, depression of foot pedal 30 will pull lid 20 open to a slightly rearwardly inclined position as shown in
Hamper bag 60 includes flaps 61 which can be passed between hamper retainer frame 14 and top frame 13 and wrapped around the respective sides of top frame 13 and secured by securement tabs 62 such that hamper 60 is held in position as shown in
Thus, the preferred embodiment utility cart provides a very lightweight, mobile hamper having a lid 20 which can be opened by depressing foot pedal 30. The control rods 40 between foot pedal 30 and hamper lid 20 can be adjusted in length such that depression of foot pedal 30 opens the lid to the position shown in
Of course, it is understood that the foregoing is a preferred embodiment of the invention and that various changes and alterations can be made without departing from the spirit of the invention as defined by the appended claims, interpreted in accordance with the principles of patent law.
