DESCRIPTION:
BRIEF SUMMARY
TECHNICAL FIELD
The invention relates to a table comprising table leaves displaceable between a first position, in which the table area is relatively small, and a second position, in which the table area is relatively large because of an insertion of additional leaves, whereby the table leaves are displaceable in radial direction relative to a vertical central axis, said table leaves being shaped in such a manner that in the first position they abut one another substantially along radial planes extending from the central axis as well as at points adjacent said central axis, and whereby the additional leaves are mutually defined along rims extending in the second position of the table leaves substantially along straight lines between the innermost point of each table leaf adjacent the central axis and the innermost point of the adjacent table leaf.
BACKGROUND ART
U.S. Pat. No. 678,948 discloses a table of the above type comprising displaceable table leaves and additional leaves which can be inserted when the table area is to be extended. The extension of the table area involves often much work, and several loose additional leaves can be difficult to handle.
CH-PS No. 514,312 discloses a table comprising displaceable table leaves and a cross-shaped additional leaf, the arms of which comprise hingedly connected outermost leaf sections. By folding the outermost leaf sections onto the remaining portion of the cross-shaped additional leaf, the additional leaf is to be horizontally stored in a chamber below the table leaves. During the placing of the additional leaf between the table leaves, it can be difficult to adjust the additional leaf so as to be on a level with the table leaves.
DISCLOSURE OF INVENTION
The object of the invention is to provide a table allowing a relatively easy rearrangement of the table leaves between the two positions simultaneous with the additional leaves being easy both to insert when the table area is to be extended and to remove and store when they are not necessary.
The table according to the invention is characterized in that the additional leaves are hingedly interconnected along their mutually defining rims, and that a vertically extending storing chamber is situated centrally below the table for the storing of the additional leaves when the table is not extended.
As a result a table is provided where the particular shape of the displaceable table leaves renders it possible to manufacture the additional leaves interconnected by means of hinges so that said additional leaves can be folded up and removed as one unit, said table leaves being stored in the storing chamber below the tabletop. In this manner the vertically extending storing chamber receives the additional leaves in a folded condition in which the leaf members--which in use in the extended table extend radially outwards between the table leaves--extend substantially vertically upwards within said storing chamber. The central position of the storing chamber has the effect that it is very easy for one person to place the additional leaves between the table leaves, and no difficulties are involved in vertically adjusting said additional leaves as said additional leaves can be placed directly on carrying means below the table leaves. The tabletop according to the invention may easily be provided with an attractive appearance both in the first and in the second position.
According to the invention the table leaves may co-operate with an underlying turning plate, the turning of which causes the radial displacement of the table leaves between the two positions, whereby said displacement of all the leaves is particularly easy and can be carried out simultaneously.
According to the invention the table leaves may be situated atop a carrying plate provided with radially extending dovetailed grooves, each dovetailed groove co-operating with a correspondingly shaped, radially extending sectional means secured to the bottom side of each table leaf, and a radially extending, through slot may be provided in the carrying plate i
