BRIEF SUMMARY
TECHNICAL FIELD
The invention relates to a table with table leaves displaceable away from one another so as to extend the table area, and with additional leaves which are hingedly interconnected and adapted to be placed between said table leaves when the latter are in the extended position, and where said additional leaves are stored in a folded condition in a storing chamber situated centrally below the table when the table leaves are in the non-extended condition, i.e. when the table leaves abut one another, said additional leaves being connected to a vertically displaceable carrying member in turn connected to a driving means.
BACKGROUND ART
Tables with additional leaves are known where the additional leaves are stored in a centrally situated storing chamber when the table is not extended, and where the moving of the additional leaves in and out of the storing chamber is facilitated by means of driving means, such as counterweights.
DISCLOSURE OF INVENTION
The object of the invention is to provide a table where the moving of the additional leaves in and out of the storing chamber can be performed in a relatively easy and gentle manner.
The table according to the invention is characterised in that guide means are provided which support each additional leaf at a substantially fixed and relatively short distance from the hinged rims thereof substantially along the entire moving path thereof.
In this manner a table is provided where the moving of the additional leaves in and out of the centrally situtated storing chamber can be performed in a relatively smooth and convenient manner. The latter is due to the fact that the unfolding is supported by the weight of the additional leaves at the same time as the additional leaves are supported by the guide means in any unfolding angle.
According to the invention the guide means of each additional leaf may comprise at least one connecting member hingedly connected both to the bottom side of the additional leaf in question and to the displaceable carrying member substantially vertically below the hinged connection to the associated additional leaf when the additional leaves are folded, both hinged connections comprising axes of rotation extending parallel to the hinged rims of the additional leaves. As a result, a particularly simple embodiment of the invention is obtained where the hinged connection of the connecting members on the additional leaves follow a circular path relative to the supporting member in a direction substantially perpendicular to the moving direction of the supporting member.
According to the invention the connecting members may be subjected to a biasing means subjecting the hinged connections of the additional leaves to a biasing force in a direction opposite the unfolding movement with the result that the unfolding movement of the additional leaves is particularly gentle.
A particularly preferred embodiment of the invention is characterised in that the connecting members are portions of U-shaped members made of spring steel, where the body of the U-shaped member is secured to the carrying member and where the legs present the connecting members.
BRIEF DESCRIPTION OF DRAWINGS
The invention is described in greater detail below with reference to the accompanying drawings, in which
FIG. 1 is a diagrammatical side view of a table according to the invention, and a vertical sectional view of a centrally situated storing chamber for the additional leaves, where the table is not extended and the additional leaves are stored in the centrally situated storing chamber,
FIG. 2 corresponds to FIG. 1, but where the additional leaves are inserted between displaced table leaves in the extended position of the table, and
FIG. 3 on a larger scale portions of the table of FIG. 1.
BEST MODE FOR CARRYING OUT THE INVENTION
The table of FIG. 1 comprises a central base designated the general reference numeral 1. Table leaves 2 are mounted on the base 1 and can be pulled away from one another in a direction perpendicular to the plane of the drawing away f
