DESCRIPTION:
BRIEF SUMMARY
The invention relates to a device for drying protective suits, for which the suit is put over a supporting framework, which consists of tubes and reaches into all extremities of the protective suit, the tubes having outlet openings at their ends for warm air that has been blown in.
In the case of an embodiment of this type, known from the EP 0468212, a supporting framework is provided, which can be assembled from several lengths of tube. Starting out from a central tube and extending over lateral connecting pieces, lengths of tube extend into the arms and legs of the protective suit. At their free ends, these lengths of tube are open, so that warm air, blown into the tubes, emerges at these ends and passes through the protective suit. This embodiment has the disadvantage that, particularly in the region of the feet, the inside of the protective suit lies against the openings, so that only a limited amount of drying air can emerge particularly there, since the boot insoles act like a butterfly valve and close off these outlet openings. The bulk of the air will then enter through the arms into the protective suit, as a result of which the foot and leg regions of the protective suit are not dried or not dried adequately. In addition, because of the large air outlet opening in the region of the arms and the hands, it is not possible to control the amounts of air in such a manner, that the required amount of drying air is also brought into the foot region of the protective suit.
The DE 3912835 A1 discloses a device for drying protective suits, for which the protective suit is suspended by the heels on a frame-like support. A manifold device for the drying air, assembled from individual tube sections, is introduced into the interior of the protective suit and, over bent end regions of the pipe sections inserted into the legs of the protective suit, suspended in the foot parts of the boots of the protective suit. The impacting of the manifold device is accomplished over an air hose, introduced into the protective suit through the entry opening.
It is an object of the invention to provide a device of the type mentioned above, with which uniform drying of the whole of the protective suit becomes possible.
Pursuant to the invention, this objective is accomplished owing to the fact that the supporting framework is formed by tubular hoops which, in the region of the feet and hands of the protective suit, have bends, in the bends of which the outlet openings for the drying air are disposed. Because of this construction, the leg and arm regions of the protective suit are held open in such a manner and, with that, the outlet openings are kept free, so that a proper drying effect occurs at all times. For protective suits, it is important that the tubular hoops hold the protective suits in such a manner, that bends, etc. are avoided in order to make an appropriate flow of drying air possible and to prevent a closing of the air outlets.
Advantageously, the outlet openings for the drying air can be directed in the curves of the bends towards the foot or finger tips of the protective suits, as a result of which it is ensured that the protective suit, put over the tubular hoops, is dried properly in all regions. Finally, the tubular hoops, in the region of the legs or arms, can have shanks, which run parallel to one another and are at a distance from one another, a shank of the hoops starting out in each case from a common manifold and the other shanks of similar hoops being connected in a conducting manner with one another. The hoops, protruding into the legs, are thus combined with one another into one piece, as are the hoops protruding into the arms, so that, on the one hand, very stable carrying frameworks are achieved and, on the other, the drying air can be blown out well, since drying air is blown in through both ends and prevented from flowing back.
For a further, advantageous embodiment, with which the protective suit can also be washed and disinfected, an additional connecting piece, which can optionally be closed of
