DESCRIPTION:
BRIEF SUMMARY
This invention relates to tables and in particular to tables of a type having round tops.
Round tables are very popular in many commercial dining applications but they have some disadvantages which are addressed by the present invention.
The first difficulty is that a round top table is not particularly convenient when being used with other round top tables in adjacent alignment.
According to this invention then there are proposed means to effect an in-fill between adjacent edges when round top tables are located in an adjoining relationship.
A number of problems still exist however with such a proposal, at least in the simplest approach.
One significant application for round top tables used in conjunction with in-fill pieces is in connection with commercial catering where various arrangements of tables will be called for from time to time including either individual round top tables, long tables, u-shaped tables and so on.
A further important aspect is that in relation to any mechanical arrangement of tables, it must be serviceable from a maintenance point of view, have an adequate or good appearance so as to appeal to an operator's clients, and it must not be especially vulnerable to breakage.
In a first aspect of this invention, there are accordingly proposed in-fill pieces to be located and adjoined thereto with respect to adjacent edges of respective round top tables.
In preference, the round top tables have tops which are each of the same diameter and height as each of the other tables so that perhaps self-evidently, the in-fill pieces are connecting between substantially identical tables.
In preference, the in-fill pieces are adapted to follow the circular periphery with respect to adjacent tables and accordingly in one arrangement an in-fill piece has an approximate triangular shape with two sides of the triangular shape having a concave alignment to match with that of the corresponding round top of a table.
In another case, the in-fill piece is substantially two such triangular pieces connected apex to apex with however a significant increase in width so that the opposite sides of the piece have an approximate semi-circular concave shape and each end is squared off.
Once one has the idea of providing an in-fill shape, there are a number of configurations which can be used to appropriately provide such in-fill and hence make the assembly of round top tables most convenient for achieving substantially all other generally useful table top shapes available.
The next problem however relates to the specifics of the table construction.
Broadly the problem is to make any construction sufficiently strong so that it will indeed be useful for all the purposes described while at the same time not getting caught with problems of appearance or in another instance providing apertures which can capture food and therefore become unsanitary.
For instance, one of the problems with using an in-fill piece is to provide means by which it can be secured to an existing round top table in such a way that it will not indeed get caught with these problems.
For instance, if there is proposed that each of the in-fill pieces have a tongue at least extending around their concave edge parts and that there is a matching slot within the edge of each circular table, the slot within each edge of the table becomes vulnerable to capture of dirt and may require constant cleaning and at the same time an outwardly extending tongue of the type being discussed becomes vulnerable to accidental impact and therefore fracture.
According to this invention there has been proposed therefore that around the edge of each of the circular top tables there be as an externally exposed surface, a convex shape when looked at in cross-section and which shape is outwardly facing from the body of the circular top table, an there is a matching complimentary shape along the respective edges of an in-fill piece, and there are clamp means adapted to engage beneath the existing respective round table top whereby to hold such respective surfaces together.
