Abstract

A table having a plurality of supports, each with a foot thereon, has interconnected cylinders mounted on two adjacent supports, with the fee mounted on the cylinder'"'"'s pistons to allow the feet to extend or retract relative to their respective supports. Because the cylinders are interconnected, the pistons, and the feet mounted thereon, move equally and oppositely of each other, until both contact the floor thereby stabilizing the table. A stabilizing device for tables includes two fluid cylinders interconnected by a conduit, adapted to be installed on adjacent supports, so that the cylinders'"'"' pistons can move inwardly and outwardly with respect to the supports on which the pistons are mounted. A method of stabilizing tables includes the step of installing interconnected fluid cylinders on adjacent supports of a table, with the pistons of the cylinders mounting the feet, so that the feet can move inwardly and outwardly with respect to supports, equally and oppositely of each other, until the feet on both pistons engage the floor, to stabilize the table.

Claims

1. In a table having at least three supports, each support having a contact surface for contacting the floor, the improvement comprising two fluid cylinders, each cylinder comprising a bore with a piston slidably mounted therein, one cylinder incorporated into each of two supports, with the contact surface on the cylinder'"'"'s piston, the cylinders in fluid communication to allow the contact surfaces to extend or retract relative to the their respective supports, equally and oppositely of each other, to stabilize the table.

2. The table according to claim 1 wherein the cylinders are incorporated into a adjacent supports.

3. The table according to claim 2 wherein the table has four supports.

4. The table according to claim 1 wherein the table has four supports.

5. A stabilizer device for installation on a table having a plurality of supports to stabilize the table on an uneven floor, the device comprising two fluid cylinders, each cylinder comprising a bore with a piston slidably mounted therein, the cylinder being interconnected by a conduit so that they are in fluid communication, and adapted to be installed on two of the supports, so that the cylinders'"'"' pistons can move inwardly and outwardly with respect to the supports on which the cylinders are mounted, equally and oppositely of each other, to, stabilize the table.

6. A method of stabilizing a table having a plurality of supports each having a contact surface for contacting the floor, the method comprising the steps of installing fluid-interconnected fluid cylinders on two of the supports, each cylinder comprising a bore with a piston slidably mounted therein, with the pistons of the cylinders mounting the contact surfaces on their respective supports, so that the contact surfaces can more inwardly and outwardly with respect to supports, equally and oppositely of each other, to stabilize the table.

7. A method according to claim 6 wherein the cylinders are installed on adjacent supports.

8. The method according to claim 6 wherein the table has four supports.
