Abstract

The invention relates to an ironing board having a natural stone surface, characterized in that the stone surface is protected against the formation of cracks - either by mechanical or localized thermal force effects - by means of a fiber coating on the underside and the natural stone ironing board is consequently also very thin and correspondingly light. In this way, the benefit of ironing on granite - utilizing the humidity stored in the stone in order to iron substantially more comfortably and faster - is fully taken advantage of and ultimately light enough and also stabilized against the formation of cracks from thermal effects. For this purpose, the thin granite plate is preferably prestressed and coated with carbon fibers.

Description

Ironing board

The present invention relates to the development of a new type of ironing board. This should have a simple construction and make the ironing easier and faster. As has been found, this is excellent with granite surfaces, as described in DE 10 2005 055 053, as these on the one hand offer an extremely hard surface and on the other hand have the favorable property to be able to store significant amounts of water, which is why tedious watering the hanger could be omitted from above. The steam is drawn out of the stone by the hot iron and evaporates on the surface, under the ironing material, which at the same time is the very desirable cooling

Effect of evaporative cooling has. Nevertheless, such an ironing board should be as light as possible so that it can be easily stowed, moved and erected by the ironing person. At this point, previous solutions of ironing boards made of granite are naturally difficult, because the stone slab is currently performed only solid because of the tendency of natural stone to break. In particular, however, even thick stone slabs are not protected against cracking when an iron remains for a long time on one and the same place the stone slab and is permanently heated, because it has forgotten to turn it off while the granite slab heats up to the point that it breaks , Measurements have shown that even at a point temperature of about 70 ° C every stone plate is cracking.

A completely new process makes it possible to stabilize natural stone so that it does not break anymore, even if it is cut very thinly and if it has to withstand high temperatures at specific points. Thin granite flagstones are coated with fibers at the bottom, which makes it possible to deliver very thin and light stone slabs that are no longer easily broken. Such stone laminate plates can be up to 1 mm thin and pre-bent or prestressed then either be self-supporting, or applied to an existing body, support plate or support frame. Among other things, such plates can also be used for cooking, because they tolerate local temperature increase, without the stone surface ruptures or bulges upwards. An ideal one

Prerequisite to transfer this principle to the ironing, as here, a crack-resistant and absolutely flat surface is necessary.

For this reason, the present invention proposes such stone-side stone-stabilized stone sheets as the surface of a stone

Ironing board or ironing frame to use.

Under the fiber-coated stone slab the usual racks can be used to support and mechanically support the slab. The flagstone is watered accordingly before ironing, whereby the fiber layer under the flagstone ensures that no water can drip down.

What is important is that the thin stone slab has grown to the local expansive forces created by local heating. For this reason, preference is given to using carbon fibers, since these are found in

Increase temperature increase less than the stone, causing the

Total composite of fiber and stone against cracking at local

Heating is additionally protected by the resulting internal pressure. Furthermore, it may be important for this reason, depending on the stone type and to be reached ironing temperature also a basic bias in the

Bonding, which also protects the stone from local cracking even in thermally high load cases, even if an iron accidentally over a long time on the stone surface in the on state or remain. One of the many possible embodiments of the invention describes in Fig. 1 a folding frame made of metal or wood (1), a support frame (2) and a thin with fibers and epoxy resin (3) coated granite natural stone slab (4), storage basket (5 ) for irons (6), with all parts (except for the iron) mechanically connected to each other. The part weighs less than 10 kg and is therefore easy to carry and set up. The stone surface gets a certain open-pored cut and is preferably not polished in order to absorb and release water quickly. In special applications, where little moisture is desired during ironing, for example, with silk fabrics, the

Surface, however, preferably be performed polished. Due to the hard surface ironing is much easier than with soft, yielding documents. Hard rock like granite is best suited, the better the porosity of the stone, the better the ability to store the necessary water.

Fig. 2 shows the ironing board with a plan view, which preferably has an oval shape.
