Receptacle with expandable cavity
View Patent ↗Various receptacle embodiments with expandable cavities are disclosed. In some embodiments, a receptacle comprising a first and second frame with a hinge permitting the first frame to pivot about the axis defined by the hinge to expand the volume of the cavity defined by the first and second frame is disclosed. In another embodiment, a receptacle comprising a first and second frame comprising a tension gear mated into a corresponding track is disclosed, permitting lateral movement between the first and second frames to expand the volume of the cavity defined by the first and second frame is disclosed. Other disclosed embodiments comprise lid and foot pedal assemblies as well as spring assist systems and other features.
1. A receptacle comprising:
a first frame;
a second frame adjoining the first frame to define a cavity with a first volume;
a hinge, defining a first axis and operatively attached to the first frame, wherein the first frame may pivot about the first axis in order to redefine the cavity with a second volume; and
a gear member comprising a first plurality of teeth disposed on an exterior surface of the second frame mated with a track comprising a second plurality of teeth disposed on an interior surface of the first frame, wherein the gear member and the track are configured to mate and permit lateral movement between the first frame and the second frame in order to redefine the cavity with the second volume, and further wherein when the gear member and the track are mated, the gear member is completely concealed between the first frame and the second frame when the receptacle is in a collapsed state.
2. The receptacle of claim 1 , wherein the receptacle further comprises a lid assembly, wherein the lid assembly abuts the cavity with the first volume and covers an aperture defined by the cavity with the first volume.
3. The receptacle of claim 2 , wherein the lid assembly further comprises:
an outer lid;
an inner lid seated within the outer lid; and
a lid hinge, defining a second axis and operatively attached to the outer and inner lid, wherein each of the outer lid and the inner lid may pivot about the second axis defined by the lid hinge independently of each other.
4. The receptacle of claim 3 , wherein the receptacle further comprises a foot pedal assembly.
5. The receptacle of claim 4 , wherein the foot pedal assembly further comprises:
a foot pedal member; and
a pivot rod defining a third axis disposed within the foot pedal assembly between the foot pedal member and a push rod operatively abutted to the foot pedal member and the lid assembly.
6. The receptacle of claim 1 , wherein the first frame further comprises a stop, wherein the stop is mated with a stop aperture disposed within the second frame.
7. The receptacle of claim 1 , wherein the receptacle further comprises a spring connecting the first frame to the second frame and configured to resist the first frame's pivot about the first axis.
