Abstract
A tilting table top mechanism includes a chassis member which is secured to the underside of a table top and a base plate which is secured to the top of a table leg. Exceptional rigidity is achieved by a dual pivot mechanism. The pivots employ novel bearing elements which are easily removed and replaceable. Pivot tabs on the base plate are insertable into recesses, or slots, in the bearing elements. At a given angle of rotation of the table top to the leg, the chassis member and base plate are readily detached. A dual locking mechanism maintains the table top in its normal horizonal position but is manually disengaged with ease.

A table top tilting mechanism for a table having a top with an underside and at least one leg having an upper end and a lower end which comprises:
- a chassis member mountable on the underside of said table top having first and second coaxial spaced pivot support members thereon defining respective first and second aligned release openings therethrough parallel to their common axis;
- a locking bolt carried by said chassis member operable between an extended locking position and a retracted unlocking position;
- means for biasing said locking bolt into said locking position;
- release handle means mountable on said table top for retracting said locking bolt to its unlocking position;
- a base plate securable to the upper end of the table top, said base plate having a first end defining a locking hole engageable with said locking bolt and a second end carrying first and second spaced pivots;
- and
- first and second pivot bearings rotatably mounted, respectively, in said first and second pivot support members, each of said bearings defining a slot for receiving a respective one of said first and second pivots, said slots being alignable with said release openings to permit said base plate to be attached to or detached from said chassis member.
A table top tilting mechanism for a table having a top with an underside and at least one top having an upper end and a lower end which comprise:
- a chassis member mountable on the underside of said table top having first and second coaxial spaced pivot support members thereon defining respective first and second aligned release openings therethrough parallel to their common axis;
- first and second spaced, parallel, locking bolts carried by said chassis member, each operable between an extended looking position and a retracted unlocking position;
- means for substantially simultaneously biasing said locking bolts into their locking positions;
- release handle means mountable on said table top for retracting said locking bolts to their unlocking positions;
- a base plate securable to the upper end of the table leg, said base plate having a first end defining first and second spaced locking engageable, respectively, with said first and second locking bolts and a second end carrying first and second spaced pivots;
- and
- first and second pivot bearings rotatably mounted, respectively, in said first and second pivot support members, each of said bearings defining a slot for receiving a respective one of said first and second pivots, said slots being alignable with said release openings to permit said base plate to be attached to or detached from said chassis member.
In a table top having a top with an underside and at least one leg having an upper end and a lower end, a top tilting mechanism which comprises:
- first and second coaxial spaced pivot support members mounted on one of (a) the table top underside or (b) the leg upper end, the pivot support members defining respective first and second aligned release openings therethrough parallel to their common axis;
- a locking bolt carried by the underside of said table top for operation between an extended locking position and a retracted unlocking position;
- means for biasing said locking bolt into said locking position;
- release handle means mounted to the underside of said table top for retracting said locking bolt to its unlocking position;
- latching means carried by the upper end of said leg for engagement with said locking bolt;
- first and second spaced pivots carried by that one of (a) the table top or (b) the upper leg end which is not carrying the pivot support members;
- and
- first and second pivot bearings rotatably mounted, respectively, in said first and second pivot support members, each of said bearings defining a slot for receiving a respective one of said first and second pivots, said slots being alignable with said release openings to permit said table top to be attached to or detached from said upper leg end.
