The invention relates to a table ( 1 ) comprising an up-and-down movable tabletop ( 2 ) and operating provisions to move the tabletop ( 2 ) up and down, characterized in that the operating provisions are located under the tabletop ( 2 ) and that they can be reached by hand. Said operating provisions preferably comprise an operating ring ( 3 ) movable against a resilient force.
1. A table comprising an up-and-down movable tabletop, and operating provisions to move the tabletop up and down wherein the operating provisions comprise an operating ring, extending along a circumferential line underneath the tabletop in the vicinity of the edge of the tabletop, said operating provisions being located in a way that they can be reached by hand under the tabletop, and wherein the operating ring is movable against a resilient force.
2. A table according to claim 1 , wherein support elements are provided, comprising at least a first part and a second part, movable in relation to each other, the tabletop being connected to the second part and in which the operating ring is provided in the area where the tabletop is connected to the second part.
3. A table according to claim 2 , wherein the first part and the second part are installed movably in relation to each other, the movement of both parts being achieved by means of a pressure spring.
4. A table according to claim 3 , wherein said pressure spring is a gas spring.
5. A table according to claim 2 , wherein the first part and the second part are two precision tubes sliding inside each other, the second part being provided with a protrusion fitting in a recess provided in the first part.
6. A table according to claim 2 wherein the operating ring is connected by bolts to the second part.
7. A table comprising an up-and-down movable tabletop, and operating provisions to move the tabletop up and down wherein the operating provisions extend over a major part of the surface of the tabletop, in the vicinity of the edge of the tabletop, said operating provisions being located in a way that they can be reached by hand under the tabletop, wherein said operating provisions comprise an operating ring, extending along a circumferential line underneath the tabletop, wherein support elements are provided, comprising at least a first part and a second part, movable in relation to each other, the tabletop being connected to the second part and in which the operating ring is provided in the area where the tabletop is connected to the second part, wherein the first part and the second part are installed movably in relation to each other, the movement of both parts being achieved by means of a pressure spring, and wherein said pressure spring is an oil spring, and wherein the operating ring is movable against a resilient force.
8. A table comprising an up-and-down movable tabletop, and operating provisions to move the tabletop up and down wherein the operating provisions comprise an operating ring, extending along a circumferential line underneath the tabletop in the vicinity of the edge of the tabletop, said operating provisions being located in a way that they can be reached by hand under the tabletop, wherein the operating ring is movable against a resilient force, and wherein to lower the tabletop, the operator pulls with his fingertips at any single place on the operating ring, while at the same time he pushes the tabletop down with the flat of his hand and by means of his body weight.
