DEVICE FOR IMPROVING THE IRONING PROPERTIES OF AN IRON

The invention relates to a device for improving the bending properties of a Iron, consisting of a removable on the ironing surface with a holder on the iron held film made of polytetrafluoroethylene, the edge of which is at least partially pulled up over the side edges of the ironing surface and the Has rows forming holes, which has raised hole edges towards the sole, which Form the first projections (according to patent application P 26 59 654.3-26).

According to the main application, the increased hole edges serve with regard to Steam distribution, among other things, to ensure an even distribution of the steam ensure that the film is not weakened too much by holes. This steam distribution should of course also work in the working state, i. H. if is pressed on the iron on the one hand and on the other hand, the soft ironing lies under the foil.

The invention aims at a further inexpensive, improved achievement of this object.

According to the invention this object is achieved in that between the rows of Holes several flat longitudinal beads extending over part of the length of the film are provided, which run approximately parallel to the rows, to the bottom the foil are open and merge into widenings at both ends.

The longitudinal beads distribute the steam coming from the top as well the steam present at the bottom even better. They hold the top edges the holes more accessible for escaping steam. Above all, these longitudinal beads meet their distribution task even in those cases in which the ironing is already is moistened and the water is now out of the ironing as a result of the heat evaporates. The longitudinal sinks also cause the steam to be far less than before emerges laterally, because on the one hand it is partially prevented from exiting from the side and on the other hand it is given a possibility of expansion in the longitudinal direction, so that β the useful portion of the steam increases.

The widenings prevent the corrugations in the course of the tent from the front or be pressed towards the back and become shorter.

The features of claim 2 ensure that the widenings «norm become rigid and can absorb the exerted forces well and at the same time that Protect items to be ironed.

The features of claim 3 avoids that the longitudinal beads for their part prevent the steam from escaping into rooms with lower pressure. Of the Flow resistance for the steam would be closed if the cells were placed close to one another high.

The features of claim 4 mean that - in contrast to embossing the longitudinal beads and cups can be easily introduced and above all are no longer thermally reversible due to the heat of the iron.

A design according to claim 5 has proven itself with the usual domestic semi-iron dimensions best proven in the given circumstances.

An exemplary embodiment of the invention will now be described. In the drawing

demonstrate:

Fig. 1 is a plan view of the top of the film, shown to scale, FIG. 2 shows a section along the line 2-2 in FIG. 1, 3 shows a section along line 3-3 in FIG. 1.

A film 11 made of Pblytetraflouräthylen has the shape shown in FIG. In front is they were held together in a bag 12 for the tip of the iron and the bag cloth are in turn held together by a rivet 13. At the beginning of the last third, two further rivets 14, 16 are inserted through the edge area the rings 17, 18 which are connected to one another by a tension spring 19 go.

809827/0624

The tension spring 19 is so long that it can move from the rear over the body of the iron can be pulled and the foil 11 holds under the sole of the iron.

Holes 21 are provided in the film, the edge 22 of which is bent upwards. the Foil 11 has a thickness of about 0.5 mm. The edge 22 is raised about 0.2 mm and 0.2 - 0.3 mm is the increase in longitudinal beads 23, 24, 26, 27, 28, 29, 31, 32.

All of these long beads 23-32 go into cups 33, 34 at their two ends about with whom they communicate.

As can be seen from Figure 1, the longitudinal bead 24 is aligned with the longitudinal bead 28, the Longitudinal bead 26 is aligned with longitudinal bead 29, all longitudinal beads are between the rows of holes 21 provided and the cups 33, 34 are always a sufficient distance from each other.

With the invention, the steam finds a way very quickly everywhere, and overheating of the plastic are thus avoided.

As you can see, the steam can essentially move forward or backward spread. The partially overlapping longitudinal beads form in the lateral direction a maze lock.

In order to make the labyrinth even tighter towards the outside, one can also use the

the dash-dotted line 35 provide a continuous, U-shaped longitudinal bead,

809827/0624

which is of course also provided in the area where the sole of the The iron exerts pressure on the items to be ironed. The longitudinal webs encompass the Line 33 engages behind all other beads and holes and the crosspiece of line 33 the longitudinal beads 31, 32. At the ends or corners of the beads one has - as indicated by dotted lines - also wells.
