Abstract
Abstract To allow adjustment of the table top of a table the table top is connected to the subframe of the table by means of a rigid U-shaped member, the branches of which are pivotally connected to the subframe about a horizontal axis, and the intermediate part of which is pivotally connected to the table top about an axis extending parallel with the pivot axis of the branches. A first telescopically extensible rod, the length of which is adjustable from a predetermined initial length which corresponds to the distance between the pivot axis of the branches and the pivot axis of the intermediate part of the U-shaped member, has one end pivotally connected with the frame at a distance from the pivot axis of the branches, and the other end pivotally connected with the table top at a distance from the pivot axis of the intermediate part, which distance corresponds to the distance between one end of the first rod and the pivot axis of the branches. A second telescopically extensible rod has one end of which is pivotally connected with the frame and the other end pivotally connected with the table top at a distance, as seen in a direction perpendicular to the pivot axis of the intermediate part, from the other end of the first rod, the pivot connections of the other rod being selected so that the other rod forms an angle different from nil together with the plane defined by the pivot axis of the branches and the pivot axis of the intermediate part.

Claim 1
Independent Claim
271 words
Table, comprising a table top which is adjustable both as regards the height and the slope of the table top, characterized by a rigid U-shaped member, the branches of which are pivotally connected to a subframe of the table about a horizontal axis, and the intermediate part of which is pivotally connected to the table top about an axis extending parallel with the pivot axis of the branches; a first telescopically extensible rod, the lengths of which is adjustable from a predetermined initial length which corresponds to the distance between the pivot axis of the branches and the pivot axis of the intermediate part of the U-shaped member, one end of the first rod being pivotally connected with the subframe of the table at a distance from the pivot axis of the branches, the other end of said first rod being pivotally connected with the table top at a distance from the pivot axis of the intermediate part, which distance corresponds to the distance between said one end of said first rod and the pivot axis of the branches; a second telescopically extensible rod, one end of which is pivotally connected with the subframe and the other end of which is pivotally connected with the table top at a distance, as seen in direction perpendicular to the pivot axis of the intermediate part, from said other end of said first rod, the pivot connections of said other rod being selected so that said other rod forms an angle different from nil together with the plane defined by the pivot axis of the branches and the pivot axis of the intermediate part.
Claim 2
Dependent Claim
271 words
Table, comprising a table top which is adjustable both as regards the height and the slope of the table top, characterized by a rigid U-shaped member, the branches of which are pivotally connected to a subframe of the table about a horizontal axis, and the intermediate part of which is pivotally connected to the table top about an axis extending parallel with the pivot axis of the branches; a first telescopically extensible rod, the lengths of which is adjustable from a predetermined initial length which corresponds to the distance between the pivot axis of the branches and the pivot axis of the intermediate part of the U-shaped member, one end of the first rod being pivotally connected with the subframe of the table at a distance from the pivot axis of the branches, the other end of said first rod being pivotally connected with the table top at a distance from the pivot axis of the intermediate part, which distance corresponds to the distance between said one end of said first rod and the pivot axis of the branches; a second telescopically extensible rod, one end of which is pivotally connected with the subframe and the other end of which is pivotally connected with the table top at a distance, as seen in direction perpendicular to the pivot axis of the intermediate part, from said other end of said first rod, the pivot connections of said other rod being selected so that said other rod forms an angle different from nil together with the plane defined by the pivot axis of the branches and the pivot axis of the intermediate part.
