ABSTRACT:
FIELD OF THE INVENTION
The invention relates to an ironing board.
BACKGROUND OF THE INVENTION
Ironing boards are commonly known. The ironing board table generally previously consisted of wood or of wood-like products such as plywood or chipboard, but for some time now has also often preferably consisted of a metal grid. Grids of this type are light and moisture-permeable owing to the many openings present. They are also firm enough, possibly with the aid of stiffening in the frame of the ironing board, which stiffening is fitted beneath the grid, to absorb the forces which are generated during ironing.
A possible drawback of the use of steel ironing board tables which can be cited is the relatively high coefficient of thermal expansion of metal. Under the influence of the heat of the iron and possibly of steam generated during ironing, the grid can be deformed such that it assumes in places a somewhat convex form under the influence of the induced thermal compression stresses. The nature of the ironing process naturally dictates that the ironing board should preferably be totally smooth and should exhibit no local bulges. In principle, ironing board tables which are not made of metal can also exhibit bulges as the result of compression stresses generated parallel to the ironing board table.
SUMMARY OF THE INVENTION
The object of the invention is an ironing board with which the problems resulting from the stresses are overcome.
The inventive ironing board includes:
an underframe; a table frame, fitted to the underframe and at least broadly flat and having a table rim which is formed from an edge profile and including stop portions; an ironing board table having an essentially flat top surface, which ironing board table, close to the periphery, is mounted on supporting portions of the table rim; the stop portions of the table rim delimit a displacement of the ironing board table in a direction parallel to the top surface thereof; and clearance(s) between the periphery of the ironing board table and the stop portions of the table rim.
The ironing board table preferably comprises a metal grid and the total clearance (

s
) parallel to the top surface of the ironing board table has an order of magnitude of at most 4-5 mm.
Preferably, the edge profile of the table rim comprises a part in the form of a horizontal U having two horizontal arms and a vertical connecting part between the two arms; the supporting portions of the table rim are formed by a first horizontal arm of the U; the stop portions of the table rim are formed by the connecting part between the arms of the U; and the second horizontal arm of the U extends over the periphery of the ironing board table, such that the periphery in a direction perpendicular to the top surface, is encased in the edge profile essentially with no or only minor clearance (t).
Preferably, the ironing board table has on the periphery a portion which is staggered relative to the other part of the top surface; and the other part of the top surface and the corresponding top surface of the table rim lie essentially in the very same flat plane.
A cover mat covers the ironing board table, the cover mat extends at the periphery over the second horizontal arm of the edge profile of the table rim.
replace the last paragraph bridging pages 1 and 2 as follows:
For a practical case, the clearance can amount to a few tenths of a millimetre, for example, which is generally sufficient. Too large a clearance causes structural problems and possibly even results in unwanted “rattling” of the table within the table frame.
By fitting the ironing board table correctly in the table frame in accordance with the invention and such that there is clearance present between those parts of the table rim which act as a stop whenever the board table is displaced in a direction parallel to the surface, an ironing board can be obtained which, in accordance with the invention, is constructed to allow a thermal expansion of the ironing board table within the table frame, or some differently founded expansion in the transverse direction, without stresses generated in a direction parallel to the ironing board table being able to result in a deformation of the ironing board table.
Preferably, an ironing board according to the invention and having the characteristics of claim

is used. For a practical case, the said clearance can amount to a few tenths of a millimetre, for example, which is generally sufficient. Too large a clearance causes structural problems and possibly even results in unwanted “rattling” of the table within the table frame.
This effect can be enhanced by a following embodiment possessing the characteristics of claim
