A table, comprising a table top consisting of at least two table top elements with each table top element and the next adjacent table top element fitting together along an abutment line. Pedestal means is provided for directly supporting at least one but not all of the table top elements. The abutment line comprises a non-straight line and at least three pairs of cooperating interfitting male and female members are provided for connecting together each table top element and the next adjacent table top element. The pairs of cooperating male and female members are disposed at spaced apart locations in a non-collinear arrangement along the or each said abutment line. The pairs of cooperating members form the sole means of support for table top elements not provided with a pedestal and the weight of such elements is carried by shear stresses in the cooperating members and by bending stresses in the table top elements themselves.
A table comprising a table top consisting of at least two table top elements, wherein each table top element and a next adjacent table top element fit together along a respective abutment line, wherein pedestal means is provided for directly supporting at least one but not all of the table top elements, wherein each said respective abutment line comprises a non-straight line, wherein at least three pairs of cooperating interfitting male and female members are provided at each said respective abutment line and are disposed at spaced apart locations in a non-collinear arrangement along said respective abutment line, with one member of each pair being located at one of said table top elements and the other member of the pair being located at said adjacent table top element, for connecting together each table top element and the next adjacent table top element, said pairs of cooperating members forming the sole means of support for table top elements not provided with a pedestal, whereby the weight of a table top element not provided with a pedestal is carried by shear stresses in the cooperating members and by bending stresses in the table top element itself.
A table which comprises two end parts and a plurality of extending leaves, said end parts and said leaves adjoining one another at respective connecting edges, wherein said connecting edges of said leaves follow a non-straight line of such formation that along said line there are at least three non-collinear points, wherein means act at at least said three non-collinear points to join two adjacent consecutive leaves preventing relative movement of the leaves in the direction perpendicular to their plane, and wherein some of the leaves have no means of stable support other than the said joining means which, on their own, would not be able to provide stable support for the leaves had the joints been collinear.
