Description

The invention relates to a device for ironing trousers, with two essentially congruent, heatable press plates, the length and width of which correspond to the corresponding dimensions of the trousers to be ironed, and which, from an open position distant from one another, for clamping trousers to be ironed into a parallel one Bring the closed position under mutual pressure, and with a feed line, by means of which steam and / or air is to be supplied to the stretched waistband during the ironing process.

"Ironing" of textile clothing or other textile products was previously understood to mean a smoothing treatment due to the technical possibilities available for this purpose, in which the object to be ironed is subjected to heat on the one hand and on the other hand - generally by applying pressure - at least to the respective one smoothing point is placed in a certain state of tension in order to either undesired wrinkles, creases or the like. to remove or the like textile object with certain folds or the like. to be provided or refreshed, as is the case, for example, when ironing trousers with respect to the crease. After the technical possibilities for this have increased considerably in the course of the years and certain smoothing treatments, in particular of garments, sometimes also take place in considerably different ways than in the case of a smoothing treatment by means of an iron, an ironing press or the like. the case is, namely, for example, in so-called steaming chambers, in which items of clothing to be smoothed are subjected to a specific steaming treatment for the purpose of smoothing, the term "ironing" has nevertheless been retained in the relevant terminology and generalized accordingly, as is also understood above and below should.

As has already been indicated above, in the past, only irons were used for ironing trousers, which were later replaced by so-called ironing presses for mass treatments in laundries, dry cleaners, clothing manufacturing companies etc. In the course of development, a wide variety of designs of ironing presses for ironing trousers have become known, the basic principle of which, however, hardly coincides other differs. This basic principle consists essentially in the fact that two so-called press plates are provided, between which the trousers to be ironed in each case are arranged, the two press plates or the like being put on when the trousers are put on. are separated from each other, and that then to remove unwanted wrinkles, creases or the like. and for the creation or preparation of the crease, generally under a certain mutual pressure of the two press plates, a heating is carried out, which is generally done by steam, but also electrically by means of heating resistors, by oil bath heating or the like. is feasible, following the heating process _. the press plates can be relatively removed again and the ironed pants can be removed.

While it is possible to iron the trouser legs and thus the crease in a quite satisfactory manner in this way, there has always been the problem of a satisfactory smoothing treatment in the region of the waistband, which accordingly had to be processed in a further step.

To avoid this, attempts have been made or the like not only a smoothing treatment of jackets, coats, but also an ironing trousers carried out in so-called damping chambers, said to be smoothed pants respectively in verti _-. Kaler arrangement arranged in such a damper chamber and be clamped in the waistband area with a tensioning device. However, it has been found that in such an ironing treatment in a steam chamber while the waist area kept taut during steaming out _- is sufficiently satisfactorily smooth, but that the strap treatment of the legs, in particular the quality of the In addition, from DE-OS 20 17 394 a device of the type described above has already become known, in which the stretched waistband of a pair of trousers to be ironed is not exposed to a steam atmosphere in the damping chambers described above, just like the rest of the trousers, but rather in which steam and / or air is selectively supplied to the stretched waistband area of a pair of trousers to be ironed, while the trouser legs are smoothed in a conventional manner between the press plates and an intermediate plate referred to above as the shaped body.

For this purpose, the waistband of a pair of trousers to be ironed is clamped onto a hanger designed in the manner of a clothes hanger and hung on a support device arranged above the intermediate plate, which is attached to a (height-adjustable) outlet of the feed line for the supply of steam and air.

Since the press plates provided in this known device, which are provided at least essentially in a vertical arrangement and each pivotally attached to a base frame at their lower end, each have essentially V-shaped waistband recesses at their upper end section, which correspond to a corresponding recess in the upper section of the intermediate plate the gaseous smoothing agent supplied through the feed line, that is to say steam and / or air, in this previously known device to the inter alia to be smoothed the waistband area of the pants, but from there through the pants fabric to the outside, whereby the waistband area not held by the press plates or the intermediate plate can freely deform outwards.

Escaping steam into the environment is highly undesirable for work physiological reasons. In addition, such a design _and mode of operation requires a relatively high amount of energy, since the steam which has flowed outward through the trousers has a considerable part in the smoothing treatment and instead heats up the surroundings in an undesirable manner.

It is also disadvantageous that the smoothing structure of the waistband area achieved in this way does not adequately take into account the requirements, since the middle waistband area outwards in relation to the firmly clamped front and rear areas of the waistband during the smoothing treatment within the framework of its elastic properties can deform so that at the "kinks", ie So at the mutually facing edges of the clamping areas, discontinuous transitions to the central waistband area can occur and the latter can bulge outward on both sides, in particular when the pressure and / or air are relatively strong.

From DE-OS 27 11 462 and 27 46 563 similar devices for ironing trousers have already become known, in which steam and / or (hot) air is to be blown into the waistband of trousers to be ironed without being known with them Devices to achieve a satisfactory result with regard to the ironing result and an economical way of working.

The present invention is therefore based on the object, the known ironing device be the beginning to improve the genus in particular in such a way that a satisfactory smoothing treatment of the entire pair of trousers is possible in a single operation, the method of operation being very economical not only with regard to the time to be used but also with regard to the energy to be used for this purpose and the operating personnel also not by steam or air escaping during the smoothing treatment.

As a solution to this problem it is provided according to the invention that at least one of the two pressure plates has a trough-shaped recess on its end portion of the inside facing the tensioning device for the waistband region of the pants to be ironed and the tensioning device, which forms a gas-tight damping chamber in the closed position of the pressure plates and with a Inlet is connected through which the steaming chamber from the feed line is to be acted upon with steam and / or air.

With the trouser press device according to the invention, it is therefore not only possible to iron the trouser legs - and thus the crease - with the high quality that can be achieved relatively quickly on such devices, but the invention also creates a possibility in one and the same operation Smoothing the entire waistband of the pants in excellent quality, whereby only a relatively low energy requirement is required, since it is not necessary, as in the known steaming chambers, to fill a large volume with steam at the appropriate temperature, but only the relatively small steaming bowl area. For reasons of symmetry and to avoid the formation of transverse folds at the lower end section of the collar area, it is preferably provided that both press plates are provided with a trough-shaped recess, which then together form the damping chamber when the press plates are closed.

In order to prevent steam blown into the steaming chamber from escaping from the steaming chamber during the steam exposure time, it is preferably provided that a seal is arranged on the edge region of at least one trough-shaped recess, which is compared to a gas-tight seal in the closed state of the pressure plates. the environment.

In view of the goal of smoothing the collar area as quickly as possible, it has proven to be particularly expedient if the inlet for the steaming chamber is provided with a blower, which is preferably designed in the manner of a nozzle, so that the steaming with the The waistband tensioning device keeps the waistband area of the trousers tight and quickly subjected to the steam blown in through the inlet, which swirls as it were and penetrates the fabric intimately.

To further improve the quality of the ironing, it is known to provide a generally covered with a textile material intermediate plate during the ironing process between the two press plates, which is folded or pushed after stretching the waistband and applying a trouser leg to the press plate on this trouser leg, whereupon then the second, previously folded back trouser leg on the other side of the intermediate plate and the other press plate is brought into the closed position. In such an embodiment, it has been shown, however, that optimal smoothing results are not always achieved in the seam region of the trousers to be ironed, so that in the embodiment of the present invention it is provided that the intermediate plate is designed to be divided in the longitudinal direction, such a division preferably being approximately takes place in the middle, in such a way that the seam regions that apply the thickness are no longer covered by the intermediate plate or the intermediate plate sections.

In such an embodiment, in which the mutually facing edges of the two intermediate plate sections are at a mutual distance from one another, it is further provided in a further embodiment of the present invention that at least one inflatable inflatable bag is arranged between the two intermediate plate sections, which inflatable bag is then in the closed state of the press plates, ie is inflated with air or / and steam during the actual ironing process and thereby lies flexibly on the seam area of the pants to be ironed. It has been shown that in such an embodiment it is expedient to provide two inflatable bags, which are then expediently arranged on an intermediate plate section and connected to an air or steam source.

The present invention is not only suitable for horizontal ironing presses of the type in question here, in which the press plates run at least substantially horizontally in the closed state, but is also evident for ironing presses with vertically running press plates in which the application of the trouser legs to the press plates or Intermediate plates are usually made with the help of negative pressure, so that the pants legs are each in a vertical arrangement of the pants, which in the waistband area with the Bund tensioning device is clamped, can be done in a very quick and easy manner.

Preferred embodiments of the present invention are described in the subclaims.

The invention is explained below using an exemplary embodiment with reference to a drawing.

• Fig. 1 eine schematisierte Darstellung einer erfindungsgemäßen Hosen-Bügelvorrichtung in - Seitenansicht, d.h. in Richtung des Pfeiles I in Fig. 2 gesehen; und
• Fig. 2 eine Draufsicht auf die Vorrichtung gemäß Fig. 1 in Richtung des Pfeiles II in Fig. 1 ohne die obere Preßplatte.

It shows:

• Figure 1 is a schematic representation of a trouser pressing device according to the invention in - side view, ie seen in the direction of arrow I in Fig. 2. and
• Fig. 2 is a plan view of the device of FIG. 1 in the direction of arrow II in Fig. 1 without the upper press plate.

For the sake of a better overview, the drawing shows a device for ironing trousers in a schematic manner, all parts which are not essential for understanding the present invention, in particular the control, steam and air ducting or the like. are omitted. The trouser press device has two essentially congruent heatable press plates 1 and 2, of which, in the illustrated embodiment, the horizontally arranged press plate 1 is firmly connected to a stand 3 containing the lines and control parts, while the upper press plate 2 is articulated via articulated connections 4 Stand 3 attached and from their horizontal closed position shown in Fig. 1 with solid lines in a designated by 2 ', with dash-dotted lines shown open position is pivotable. For the sake of clarity, the upper press plate 2 has been omitted in FIG. 2.

The length and width or depth of the press plates 1, 2 is equal to the corresponding dimensions of the trousers to be ironed and essentially corresponds to the corresponding dimensions of conventional trouser-ironing devices.

At the end section of the lower press plate 1 on the left in the drawing, a known collar tensioning device for releasably fastening the waistband of trousers to be ironed is arranged. The tensioning device consists of a stationary tensioning block 6 as well as a tensioning roller 7 movable transversely to the longitudinal direction of the device in the direction of the double arrow 8.

At its end section facing the collar tensioning device 6, 7, the lower press plate 1 is provided with a downwardly extending, trough-shaped formation or recess 9, in which the clamping device 6, 7 is arranged, and in which the collar area is located during the ironing process the pants to be ironed. In addition, in the area of the trough-shaped recess 9 there is an inlet 11, through which steam or air can be blown in in the direction of the arrows 12, the inlet 11 in the drawing being preceded by a blower with a nozzle-shaped blower housing, not shown in detail.

The upper press plate 2 is also provided with a trough-shaped recess or recess 13 which corresponds to the trough-shaped recess 9 of the lower press plate 1 and which is particularly good from that in FIG. 1 with dash-dotted lines Lines shown folded up position can be seen, in which the formation 13 is designated 13 '. Around the edge of the somewhat asymmetrical recess 13 there is a continuous seal 14 which, in the closed state shown in FIG. 1 by solid lines, lies sealingly against the edge 16 of the recess 9 of the lower press plate 1, so that in the closed state the two trough-shaped recesses 9 and 13 of the press plates 1 and 2 together form a closed small damping chamber, as will be explained further below.

Between the two press plates 1, 2 there is an intermediate plate consisting of two sections 17 and 18. As can be seen in particular from FIG. 2, the two intermediate plate sections 17, 18 are each articulated with two hinge-like joints 19 on the lower press plate 1 or the stand 3 and can be swiveled up from their state in contact with the lower press plate 1 according to FIG. 2.

The mutually facing edges 17 'and 18' of the intermediate plate sections 17 and 18 are at a mutual distance a from one another, which varies somewhat over the length of the intermediate plate sections 17, 18, and are each connected to an inflatable bag 21, which via lines and control means, not shown air or steam must be applied during the ironing process.

• Das Einlegen einer zu bügelnden Hose erfolgt bei hochgeschwenkter oberer Preßplatte 1 und von der unteren Preßplatte 2 weggeschwenkten Zwischenplattenabschnitten 17 und 18, so daß die Oberseite der unteren Preßplatte in diesem Zustand frei zugänglich ist. In diesem Zustand wird eine zu bügelnde Hose flach auf die untere Preßplatte 1 gelegt und mit ihrem Bund an der Spanneinrichtung 6, 7 befestigt. Letzteres erfolgt derart, daß die vordere Gürtelpartie der Hose um den Spannblock 6 gelegt und dort in an sich bekannter Weise mit Andrückplättchen fixiert wird, die von oben und unten gegen das Mittelteil des Spannblockes drücken, und daß sodann die hintere Gürtelpartie der Hose über die in Richtung des Pfeiles 8 bewegliche Spannrolle 7 geführt wird, wobei die Spannrolle 7 so weit nach außen geführt wird, bis der Hosenbund in der Spanneinrichtung 6, 7 fest eingespannt ist. Dieses Spannen kann entweder von Hand erfolgen, wobei insbesondere das Spannen und Gespannthalten der Spannrolle 7 aber auch mittels eines geeigneten Antriebes mechanisiert erfolgen kann. _;

The operation with the trouser press device described above and shown in the drawing is as follows:

• A pair of trousers to be ironed is inserted with the upper press plate 1 swung up and from the lower press plate 2 pivoted intermediate plate sections 17 and 18 so that the top of the lower press plate is freely accessible in this state. In this state, trousers to be ironed are placed flat on the lower press plate 1 and fastened with their collar to the tensioning device 6, 7. The latter is done in such a way that the front belt section of the pants is placed around the tensioning block 6 and fixed there in a manner known per se with pressure plates which press against the middle part of the tensioning block from above and below, and that the rear belt section of the pants then over the in Direction of arrow 8 movable tensioning roller 7 is guided, the tensioning roller 7 being guided outward until the waistband is firmly clamped in the tensioning device 6, 7. This tensioning can either be done by hand, but in particular the tensioning and tensioning of the tensioning roller 7 can also be mechanized by means of a suitable drive. _;

Then the upper leg is turned to the left so that the lower leg can be spread smoothly on the lower press plate 1. For this purpose, a suction provided on the lower press plate 1 can be used, by means of which a negative pressure can be generated on the upper side of the press plate 1, the suction being switchable with a foot pedal 22 provided.

Then the two intermediate plate sections 17, 18 with the inflatable bags 21 on them, not yet inflated, are pivoted down into the position shown in FIG. 2, in which they therefore rest on the inside of the lower leg, so that the second leg now on the textile-coated Intermediate plate sections 17, 18 and the inflatable bags 21 placed and from Can be pre-smoothed by hand, with which the entire laying work is already finished and the actual ironing process can begin. For this purpose, the machine is closed by means of two-hand operation, ie the upper press plate 2 is folded down from its position labeled "in FIG. 1, whereupon the ironing process is controlled by means of a machine control. Conventional time clock systems, program card-controlled devices or even small computers can serve as control devices, how this is known per se.

With the actual beginning of the ironing process, steam is not only applied to the permanently heated, perforated press plates 1, 2 for moistening the trousers to be ironed by opening a valve, but steam is also blown through the inlet 11 into the steaming trough 9, 13 . In addition, the inflatable bags 21 are inflated at the same time. This has the consequence that the trouser legs are ironed under heat and pressure in the area of the crease between the pressure plates 1, 2 and the intermediate plate sections 17, 18, and that at the same time the tensioned collar section in the steaming trough 9th , 13 is subjected to a smoothing treatment. In addition, the desired smoothing effect also occurs in the area of the trouser seams, since the inflatable bags 21 nevertheless lie closely against the trousers, but nevertheless allow a certain deformation in the thickened immediate seam region. The contact pressure can be controlled in a known manner, and the fixation following the actual ironing process is also carried out in a conventional manner by suction, by applying a vacuum to the two pressure plates 1, 2 in a conventional manner at openings arranged in a distributed manner, the processing possibly being carried out by a so-called re-steaming or glossing can be supplemented if necessary with press plates 1, 2 still closed but no longer pressing.

After the actual ironing process, the upper press plate 2 is first pivoted up slightly by a few centimeters, so that air and / or steam can be blown through the inlet 11 and then blown over the entire trousers, since in this partially opened state the seal 14 the steaming trough 9, 13 is no longer effective, so that the air flowing into the steaming trough 9, 13 through the inlet 11 in the direction of the arrows 12 can escape from the steaming trough and flow through the pants.

In the case of an incorporated operator, the entire processing time takes less than a minute, with an extremely satisfactory result being achieved, since all areas of the pants can be smoothed in one operation in an optimal manner and in the shortest possible time with the pants ironing device according to the invention.
