Abstract

The leg socket has a plurality of circumferentially spaced apart ribs extending along an interior wall. Each rib has a concavely curved surface extending longitudinally and disposed on a common radius of the wall to provide contact with a cylindrical table leg over a surface.

Claims

1. A leg socket comprising

a hollow shell including a cylindrical wall, a radially outwardly directed flange at one end of said wall and a radially inwardly directed lip at an opposite end of said wall;

a plurality of circumferentially spaced apart elongated ribs extending along an interior of said wall and being part thereof, each said rib having a concavely curved surface extending longitudinally thereof and disposed on a common radius of said wall.

2. A leg socket as set forth in claim 1 wherein said ribs are circumferentially spaced on an angle of 72°

relative to each other.

3. A leg socket as set forth in claim 1 further comprising a threaded bore disposed in said wall between a pair of said ribs and a set screw threaded into said bore.

4. A leg socket as set forth in claim 1 wherein each said rib is of elongated shape having a pair of parallel side walls, a first rounded end wall at one end of said parallel side walls, a second rounded end wall at an opposite end of said parallel side walls and a floor extending between said side walls and opposite said concavely curved surface.

5. A leg socket as set forth in claim 4 wherein said floor is convexly curved between said side walls.

6. In combination,

a cylindrical leg for a table having a predetermined diameter;

and

a leg socket receiving said leg, said leg socket having a wall and a plurality of circumferentially spaced apart elongated ribs extending along an interior of said wall and being part thereof, each said rib having a concavely curved surface extending longitudinally thereof and slidably receiving said leg.

7. The combination as set forth in claim 6 wherein said leg socket has a radially outwardly directed flange at one end of said wall and a radially inwardly directed lip at an opposite end of said wall.

8. The combination as set forth in claim 6 wherein said leg socket has a threaded bore disposed in said wall between a pair of said ribs and a set screw threaded into said bore and abutting said leg.

9. The combination as set forth in claim 6 wherein each said rib is of elongated shape having a pair of parallel side walls, a first rounded end wall at one end of said parallel side walls, a second rounded end wall at an opposite end of said parallel side walls and a floor extending between said side walls and opposite said concavely curved surface.

10. The combination as set forth in claim 9 wherein said floor is convexly curved between said side walls.

11. The combination as set forth in claim 6 wherein said leg socket is cylindrical in cross-section.

12. A leg socket comprising

a one piece hollow shell including a cylindrical wall, a radially outwardly directed flange at one end of said wall, a radially inwardly directed lip at an opposite end of said wall, and a plurality of circumferentially spaced apart elongated ribs extending along an interior of said wall, each said rib having a concavely curved surface extending longitudinally thereof and disposed on a common radius of said wall.

13. A leg socket as set forth in claim 12 wherein each said rib is of elongated shape having a pair of parallel side walls, a first rounded end wall at one end of said parallel side walls, a second rounded end wall at an opposite end of said parallel side walls and a floor extending between said side walls and opposite said concavely curved surface.

14. A leg socket as set forth in claim 13 wherein said floor is convexly curved between said side walls.
