Collapsible table

Claim 2

A collapsible table comprising a substantially vertical, tabletop support member, a tabletop pivotally mounted at the upper end of the support member, a plurality of legs, the upper ends of which are secured on the support member, at least one of the legs being movable from a collapsed position to an extended position or from an extended position to a collapsed position when the tabletop in the first instance is pivoted from a position of non-use to a position of use or, in the second instance, is pivoted froM a position of use to a position of nonuse, and leg actuating means joined at its upper end to the pivotable tabletop, said leg actuating means having a movable leg-engaging portion provided with flat surface areas which are adapted to engage cooperating leg moving means at the upper end of said at least one movable leg, the flat surface areas of the leg-engaging portion coacting with said leg moving means to move the said at least one movable leg from either a collapsed position to an extended position or from an extended position to a collapsed position when the tabletop in the first instance is pivoted from a position of non-use to a position of use or, in the second instance, is pivoted from a position of use to a position of non-use, said leg-engaging portion being twisted whereby the flat surface areas engaging said leg moving means lie in one vertical plane when the movable leg is in a collapsed position and in a different vertical plane when the movable leg is in an extended position.

Claim 3

A table according to claim 1 wherein four legs are provided for the table, two of which are stationary and two of which are movable in response to pivotal movement of the tabletop.

Claim 4

A table according to claim 1 wherein the leg moving means at the upper end of said at least one movable leg comprises an opening, the side margins of which coact with the flat surface areas of the movable leg-engaging portion of the leg actuating means to move the said at least one movable leg from a collapsed position to an extended position or from an extended position to a collapsed position in response to pivotal movement of the tabletop.

Claim 5

A table according to claim 1 wherein the movable leg-engaging portion of the leg actuating means is an elongated bar of substantially rectangular cross-section which has been twisted along its longitudinal axis to provide a pair of flat surface areas which lie in vertical planes which are at an angle to the vertical planes normal to the longitudinal axis of the bar.

Claim 6

A table according to claim 3 wherein the leg moving means at the upper end of said at least one movable leg comprises a cap member fixedly supported at the upper end of said at least one movable leg, said cap member having a slot formed therethrough for receiving the movable leg-engaging portion of the leg actuating means.

Claim 7

A table according to claim 1 wherein the said at least one movable leg is provided with an opening for receiving leg retaining means on the tabletop support member whereby the movable leg can be freely moved from a collapsed to an extended position, or vice versa, while being maintained in position on the support member.

Claim 8

A collapsible table comprising a substantially vertical, tabletop support member, a tabletop pivotally mounted at the upper end of the support member, a plurality of legs, the upper ends of which are secured on the support member, two of the legs being movable from a collapsed position to an extended position or from an extended position to a collapsed position when the tabletop in the first instance is pivoted from a position of non-use to a position of use or, in the second instance, is pivoted from a position of use to a position of non-use, leg actuating means joined at its upper end to the pivotable tabletop, said leg actuating means having spaced, movable leg-engaging portions provided with flat surface areas which are adapted to engage cooperating leg moving means at the upper end of each movable leg, the flat surface areas of the leg-engaging portions coacting with said leg moving means to move the movable legs from either a collapsed position to an extended position or from an extended position to a collapsed position when the tabletop in the first instance is pivoted from a position of non-use to a position of use or, in the second instance, is pivoted from a position of use to a position of non-use, each of said leg-engaging portions being twisted whereby the flat surface areas engaging said leg moving means lie in one verticAl plane when the movable legs are in a collapsed position and in a different vertical plane when the movable legs are in an extended position, and releasable tabletop retaining means for maintaining the pivotal tabletop in a horizontal position when the collapsible table is in use.

Claim 9

A collapsible table comprising a substantially vertical, tabletop support member, a tabletop pivotally mounted at the upper end of the support member, a plurality of legs, the upper ends of which are secured on the support member, two of the legs being movable from a collapsed position to an extended position or from an extended position to a collapsed position when the tabletop in the first instance is pivoted from a position of non-use to a position of use or, in the second instance, is pivoted from a position of use to a position of non-use, leg actuating means joined at its upper end to the pivotable tabletop, said leg actuating means having spaced, movable leg-engaging portions provided with flat surface areas which are adapted to engage cooperating leg moving means at the upper end of each movable leg, the flat surface areas of the leg-engaging portions coacting with said leg moving means to move the movable legs from either a collapsed position to an extended position or from an extended position to a collapsed position when the tabletop in the first instance is pivoted from a position of non-use to a position of use or, in the second instance, is pivoted from a position of use to a position of non-use, each of said leg-engaging portions being twisted whereby the flat surface areas engaging said leg moving means lie in one verticAl plane when the movable legs are in a collapsed position and in a different vertical plane when the movable legs are in an extended position, and releasable tabletop retaining means for maintaining the pivotal tabletop in a horizontal position when the collapsible table is in use.

Claim 10

A table according to claim 7 wherein the leg actuating means comprises a bifurcated member having spaced, movable leg-engaging portions, said member being pivotally joined at one end to the tabletop.

Claim 11

A table according to claim 7 wherein the leg-engaging portions of the leg actuating means are twisted in opposite directions whereby the flat surface areas thereof lie in intersecting vertical planes.

Claim 12

A table according to claim 7 wherein the movable legs are each provided with an opening for receiving leg retaining means on the tabletop support member whereby the movable legs can be freely moved from a collapsed to an extended position, or vice versa, while being maintained in position on the support member.
