Tilting tabletop mechanism
View Patent ↗An article of furniture has been developed having a tilting tabletop mechanism, which securely maintains a tabletop in either a generally horizontal or generally vertical position while permitting a user to tilt the tabletop easily. The article of furniture includes a first component, a second component, a first member, a second member, a first lock element, and a second lock element. The second component is pivotally coupled to the first component. The first and second members are connectable to a first secured component. The first secured component is one of the first and second components. The first lock element is mounted to engage the first member when the first component is in a first position relative to the second component. The second lock element is mounted to engage the second member when the first component is in a second position relative to the second component.
1. An article of furniture comprising:
a table top having an underside;
at least one leg rotatably coupled to the underside, the at least one leg having a locking bar;
at least one locking mechanism rotatably coupled to the underside, the locking mechanism including a hook configured to engage the locking bar, and the locking mechanism configured to rotate the hook into and out of an engaging position in which the hook engages the locking bar; and
an actuator coupled to the at least one locking mechanism and coupled to the underside to slide longitudinally along the underside to rotate the hook into and out of the engaging position,
wherein the actuator includes:
a plate slidably coupled to and configured to slide longitudinally along the underside;
a hand grip coupled to the plate and slidably coupled to the underside, the hand grip configured to enable a user to pull the actuator to slide the plate longitudinally along the underside; and
a rod rotatably coupled to the plate and rotatably coupled to the at least one locking mechanism, the rod configured to rotate the at least one locking mechanism when the user pulls the actuator and slides the plate longitudinally along the underside.
2. The article of furniture of claim 1 , wherein:
the underside of the table top is substantially planar;
the plate is substantially planar and is substantially parallel to the underside; and
the rod is arranged at an angle relative to the underside and relative to the plate.
3. The article of furniture of claim 1 , further comprising a biasing mechanism coupled to the at least one locking mechanism and configured to bias the at least one locking mechanism into the engaging position.
4. The article of furniture of claim 1 , wherein the hand grip is sized so as to enable a user to grip the hand grip to pull the actuator with one hand.
5. The article of furniture of claim 1 , further comprising fastening members configured to fasten the plate to the underside.
6. The article of furniture of claim 5 , wherein the plate includes slots configured such that the fastening members are inserted through the slots to couple the plate to the underside.
7. The article of furniture of claim 6 , wherein the slots have a length and the plate is slidable over a distance equal to the length of the slots.
8. The article of furniture of claim 7 , wherein the rod is movable over a distance equal to the length of the slots.
