Rotating base with pull-out system

Claim 2

A rotating base with a pull-out system for furniture comprising: a member secured to the furniture so that said member can be rotated about a vertical axis; said base being rotatable with said member and linearly slidable relative to said member via runway rails mounted therebetween, and having coupling means for predetermining a sliding position of said base relative to a rotating position of said member and for predetermining a rotating position of said member relative to a sliding position of said base; wherein said coupling means includes a guide pin attached to a stationary support fixed to the furniture, said guide pin in engagement with a control groove formed on the underside of the rotating base; wherein said control groove has a circular arc-shaped section having one end progressively extending into a rectilinear section running parallel to said runway rails; and wherein the center of curvature of the circular arc-shaped section coincides with the axis of rotation of the member when the rotating base is located in an initial position inside the furniture.

Claim 3

The rotating base according to claim 1, wherein the rotating base comprises a plastic part in one piece, in which the control groove has been injected and which has an edge extending downwards for screening the runway rails, the member and the coupling means.

Claim 4

A rotating base with a pull-out system for furniture comprising: a tube attached at its upper and lower ends thereof to the furniture, said tube thereby extending vertically inside the body of the furniture and being fixed against rotation in relation to the furniture; a support attached rigidly at one end to the tube whereby said support projects into the inside of the furniture, the other end of said support being unattached to said tube and bearing a guide pin; a member supported by said support and secured to the furniture so that said member can be rotated about said tube; and said base being rotatable with said member and linearly slidable relative to said member via runway rails mounted therebetween, and having said guide pin attached to said support for predetermining a sliding position of said base relative to a rotating position of said member and for predetermining a rotating position of said member relative to a sliding position of said base.

Claim 5

A rotating base with a pull-out system for furniture comprising: a tube attached at its upper and lower ends thereof to the furniture, said tube thereby extending vertically inside the body of the furniture and being fixed against rotation in relation to the furniture; a support attached rigidly at one end to the tube whereby said support projects into the inside of the furniture, the other end of said support being unattached to said tube and bearing a guide pin; a member supported by said support and secured to the furniture so that said member can be rotated about said tube; and said base being rotatable with said member and linearly slidable relative to said member via runway rails mounted therebetween, and having said guide pin attached to said support for predetermining a sliding position of said base relative to a rotating position of said member and for predetermining a rotating position of said member relative to a sliding position of said base.

Claim 6

The rotating base according to claim 3, wherein the support comprises a plastic part slid onto the tube said support being provided with a groove on an underside thereof, said groove receiving a pin introduced through a transverse hole in the tube.

Claim 7

A rotating base with a pull-out system for furniture comprising: a member secured to the furniture so that said member can be rotated about a vertical axis, said member being constructed in the form of a frame; said base being rotatable with said member and linearly slidable relative to said member via runway rails mounted therebetween, and having coupling means for predetermining a sliding position of said base relative to a rotating position of said member and for predetermining a rotating position of said member relative to a sliding position of said base; a stationary support attached to the furniture and supporting said member; a control groove formed on the underside of the rotating base and arranged symmetrically with the axis of symmetry of the rotating base; said coupling means including a guide pin and an interchangeable stop pin; said guide pin attached to the support and which engages said contral groove, said guide pin defining a terminal position of the member when a side of the member contacts said guide pin; and said interchangeable stop pin attached to the support, said stop pin defining another terminal position of the member when another side of the member contacts said stop pin.

Claim 8

A rotating base with a pull-out system for furniture comprising: a member secured to the furniture so that said member can be rotated about a vertical axis, said member being constructed in the form of a frame; said base being rotatable with said member and linearly slidable relative to said member via runway rails mounted therebetween, and having coupling means for predetermining a sliding position of said base relative to a rotating position of said member and for predetermining a rotating position of said member relative to a sliding position of said base; a stationary support attached to the furniture and supporting said member; a control groove formed on the underside of the rotating base and arranged symmetrically with the axis of symmetry of the rotating base; said coupling means including a guide pin and an interchangeable stop pin; said guide pin attached to the support and which engages said contral groove, said guide pin defining a terminal position of the member when a side of the member contacts said guide pin; and said interchangeable stop pin attached to the support, said stop pin defining another terminal position of the member when another side of the member contacts said stop pin.

Claim 9

The rotating base according to claim 5, wherein the rotating base comprises a plastic part in one piece, in which the control groove has been injected and which has an edge extending downwards for screening the runway rails, the member and the coupling means.
