Push-push cup holder
A cupholder has a substantially tubular shell configured to be mounted with a longitudinal axis oriented substantially vertically. A floor received in the shell is vertically movable along the longitudinal axis for defining a variable depth cup well. A ring coaxially atop the shell has a plurality of vertical guide extensions disposed around a periphery of the shell. The ring is vertically movable. A linkage is provided between the floor and the guide extensions providing reciprocal motion of the floor and the ring wherein pushing down the floor raises the ring and wherein pushing down the ring raises the floor.
1. A cupholder comprising:
a substantially tubular shell configured to be mounted with a longitudinal axis oriented substantially vertically;
a floor received in the shell and vertically movable along the longitudinal axis for defining a variable depth cup well;
a ring coaxially atop the shell having a plurality of vertical guide extensions disposed around a periphery of the shell, wherein the ring is vertically movable; and
a linkage between the floor and the guide extensions providing reciprocal motion of the floor and the ring wherein pushing down the floor raises the ring and wherein pushing down the ring raises the floor, wherein the linkage is comprised of a plurality of rockers, wherein each rocker is coupled to the floor and to a respective guide extension and wherein each rocker comprises:
a pivot arm;
a first push rod coupled between a first end of the pivot arm and a respective guide extension; and
a second push rod coupled between a second end of the pivot arm and the floor, wherein the pivot arm is pivotably attached to the shell at a pivot point between the first and second ends.
2. The cupholder of claim 1 wherein the shell comprises a plurality of yokes, each yoke attached to a respective pivot arm at the pivot point.
3. The cupholder of claim 2 wherein each yoke is comprised of a clip having a channel for applying a progressive squeezing force on the pivot arm to provide a frictional force for holding the floor and ring in at least one predetermined position.
4. The cupholder of claim 1 wherein the first push rod is joined to the respective guide extension by a first claw-style joint, and wherein the second push rod is joined to the floor by a second claw-style joint.
5. The cupholder of claim 1 wherein the shell has an outer tubular surface having a plurality of guide rails receiving the guide extensions.
6. The cupholder of claim 1 wherein the shell includes an upper flange with a plurality of slots each slidably receiving a respective guide extension.
7. The cupholder of claim 6 wherein the floor and the ring have a neutral position in which the ring is disposed against the flange and the floor is substantially coplanar with the flange.
8. The cupholder of claim 7 wherein the floor and the ring have a deployed position in which the cup well is at a maximum depth and the ring is at a maximum height above the upper flange.
9. The cupholder of claim 1 wherein the shell is substantially cylindrical, wherein the floor is comprised of a circular plate, and wherein the ring is substantially circular.
10. A cupholder system comprising:
a substantially horizontal surface adjacent a seat, wherein the horizontal surface includes an aperture;
a substantially tubular shell mounted within the aperture with a longitudinal axis oriented substantially vertically;
a floor received in the shell and vertically movable along the longitudinal axis for defining a variable depth cup well;
a ring coaxially atop the shell having a plurality of vertical guide extensions disposed around a periphery of the shell, wherein the ring is vertically movable; and
a linkage between the floor and the guide extensions providing reciprocal motion of the floor and the ring wherein pushing down the floor raises the ring and wherein pushing down the ring raises the floor
wherein the shell includes an upper flange with a plurality of slots each slidably receiving a respective guide extension, and wherein the upper flange overlies an edge of the aperture.
11. The cupholder system of claim 10 wherein the floor and the ring have a neutral position in which the ring is disposed against the flange and the floor is substantially coplanar with the horizontal surface, and wherein the floor and the ring have a deployed position in which the cup well is at a maximum depth and the ring is at a maximum height above the upper flange.
12. The cupholder system of claim 10 wherein the horizontal surface is comprised of an armrest associated with the seat.
13. The cupholder system of claim 10 wherein the horizontal surface is comprised of a beverage tray associated with the seat.
14. The cupholder system of claim 10 wherein the horizontal surface is comprised of a console of an automotive vehicle.
