 Figure 1-4 schematically shows an example of the implementation of the press according to the invention in the closed and open positions. Press 1 contains a detachable, as a rule, lightweight plastic casing 2 (shown in FIGS. 5-8), in which two essentially rectangular pressing ironing plates 3 are placed, a separation plate 4 with a cutout 5 in its upper part, located between the pressure plates and base. Cutout 5 allows the trousers to be positioned in such a way that one leg is placed on one side of the separation plate 4, the second on the other side of the plate 4, the waist part is above its edge, and the step part is in the cutout 5. According to a preferred embodiment of the invention, each pressing ironing plate mounted pivotally, and the separation plate has a rigid fastening. In such a preferred embodiment, the press has structural rigidity, which ensures the efficiency of the ironing process. Nevertheless, it is possible that the pressing ironing plates have a common axis of rotation, and the separation plate is also mounted with the possibility of slight movement relative to the pressing plates. In the described preferred example, the pressing ironing plates 3 of the press have concave sections 6 (see FIG. 4) that are mated in shape with the cutout of the separation plate 5, which allows you to smooth the trousers along the entire length, including their upper part. The pressure plates can be made of various materials, for example, metal, ceramics, etc., and the separation plate, as a rule, has a rigid base (metal, plastic, mesh, etc.), covered with a soft cover consisting of batting and fabric or other materials.

 A heat-insulating plate can be installed between the casing 2 and the pressing ironing plate 3 to reduce heat dissipation.

 The base 7 of the press includes a lower part 8 and a side vertical part 9. The base 7 may be made of a single metal, plastic (molded or pressed) or composite. In a composite base, the parts are interconnected by welding, screws or other suitable mounting method. The lower part 8 of the base may be provided with support elements.

 The press can be made with a base having a second lateral vertical part, while the vertical parts are located on both sides of the pressing ironing plates, which can improve, if necessary, the rigidity of the structure and facilitate the placement of means for opening and pressing the pressing ironing plates.

 In the vertical part 9 there is a sliding rod 10, a guide 11 of the rod and a boom 12 rigidly connected to the rod. The sliding rod 10 is moved along the guide 11 located in the upper part of the vertical part 9 of the base. The arrow 12 is provided with a means for holding the waist of the trousers (not shown). The retaining belt part means can be made, for example, in the form of clips such as clothespins (lever, screw, etc.). It is advisable to use three clamps, and the left and right clamp can be made spring-loaded relative to the middle clamp to expand the waist part. The boom 12 can also be additionally equipped with a separate tool, also helping to straighten the upper part of the trousers, made in the form of a spring-arm extender.

 The press is configured to connect to a power source. The control mechanism of the press contains an electronic control unit, as well as a control panel, providing an automatic mode of the ironing process. The control panel contains means for setting ironing modes in the form of controls and signal elements such as handles, buttons and the like. The press according to the invention can have several ironing modes, allowing you to change the temperature and time of ironing depending on the parameters of the trousers (fabric, size, style), and on the desire of the user. An electronic control unit and at least one drive mechanism for driving means for opening and pressing the pressing ironing plates and the control of the pull-out bar (shown under general reference position 13) are installed in the lower part of the base 8. It is advisable to install two drive mechanisms, one on opening and pressing the pressing ironing plates 3, and the other to control the sliding rod 10. The drive mechanism for opening and pressing the pressing ironing plates 3 and controlling the sliding rod 10 can be nen a suitable electric motor with suitable gear and transmission, e.g., in the form of ropes or pulleys, gears system, spindles and the sliders etc. It will be appreciated that suitable gears of a different type may also be used. A control panel (not shown) is typically located at the top of the vertical portion 9 for the convenience of the user.

 Figure 1 and figure 4 show the press in the folded initial position, while figure 2 and figure 3 show the press in the open position with the extended bar.

 In FIG. 5 shows a variant of the mechanism for opening and pressing the clamping ironing plates 3. The separation plate 4 is rigidly, and each clamping ironing plate 3 is pivotally mounted on the base 7. Each clamping ironing plate 3 has its own axis of rotation 14. The clamping ironing plate 3 is fixed to the base with the swivel, in the example shown, is an elongated hinge 15 mounted on the axles 14, by means of which the pressing ironing plates 3 are fixed in the base. There are various ways of fixing the pressure plates 3 on the hinges 15. The fixing can be rigid, performed using a single welded frame. In the preferred embodiment of the invention shown in FIG. 5, fixing is done on the axles 16 through an arm 17 fixed to the pressure ironing plate 3. This method of fixing the pressure ironing plate 3 on the hinges 15 shown in FIG. 5 allows the pressure ironing plate make a small swinging motion relative to the loop 15, which improves the quality of ironing by adapting the pressure plates during the ironing process of trousers of different sizes, thicknesses of material and different cuts. In the hinges 15, inclined grooves 18 are made in which the slider 19 moves. Moving the slider causes opening or pressing of the pressing ironing plates.

 Preferably, on the sides of the casing 2 covering the pressing ironing plates, windows 20 are made in its lower part, which allows unloading the lower part of the trousers from the press when lowering the boom 12. The windows 20 are closed by hinged doors 21, which also serve to accommodate the lower part of the trousers during ironing process.

 The mechanism for opening and closing the hinged doors 21, shown in Fig.6 and Fig.7, in this example includes a loop 22, the axis 23 and 24; the sliders 25, the springs 26 and the levers 27 holding the hinged door 21. The hinged doors 21 for closing the windows are connected to the drive mechanism through the slider 25 and open when the pressure ironing plates open and close when the pressure plates close. The hinged doors 21 through the axles 23 are mounted on the hinges 22, rigidly attached to the hinge 15. The axles 24 are also fixed on the hinges 15. On the axes 24 there are sliders 25 with levers 27, which are connected at the other end to the hinged doors 21, and the springs 26. It is clear that the mechanism for opening and closing doors 21 can also be made in the form of a gear transmission, flexible connection, etc. Hinged doors 21 for closing the windows, it is advisable to make the material of the casing, so that in the closed state they covered the windows flush with the casing to facilitate carrying and improve the appearance of the product.

 According to a preferred embodiment of the invention, a fluid container and a pump (shown under general reference 28) may be provided in the press. The liquid container can be rotatable around a vertical axis, which will allow it, if necessary, to extend beyond the press casing for filling water. The container may be removable or stationary. In the above example of the execution of the press, a container for placing liquid and a pump are installed in the lower part of the base, and devices for spraying liquid are made in the form of nozzles 29 located in the casing 2 above the upper part of the pressing ironing plates 3 for spraying trousers. In a preferred embodiment, heating elements (not shown) are mounted on the pressing ironing plates 3, and the separation plate 4 preferably has a soft coating (not shown). The heating element may be installed in a separation plate or in each press plate.

 Between the lower edge of the separation plate and the window, it is advisable to place a guide surface 30 for guiding the lower part of the trousers, which can be made integral with the casing of the lower part of the base, as shown in Fig.6 and Fig.7. The guide surfaces 30 help the trousers exit onto the hinged doors 21.

 According to a preferred embodiment of the invention, the press 1 is provided with means for gripping and extending the lower part of the trousers for fixing and extending the trousers. This tool is associated with a drive mechanism that controls the extension of the rod 10. Two versions of this tool are shown in Fig.6 and Fig.7. In Fig.6, the means of gripping and straightening the lower part of the trousers is made in the form of a clamping device on two rollers 31, 32, while the rollers 31 are wired, and the rollers 32 are clamping, working on friction. The trouser gripping and straightening tool can be with one drive roller, as well as in the form of the endless belt 33 shown in Fig. 7 mounted on the rollers 34, 35. The roller 34 is a forced rotation roller (drive), and the roller 35 operates on friction. The axis 36 serves to fold the belt 33 at the end of the ironing process and folding the press 1, as shown in Fig. 8.

 The appearance of the press according to the embodiment described above is shown in FIG. 9 and 10. Figure 9 illustrates the press in a closed, networked position, and Figure 10 shows the press in the open position before refueling the trousers. In these figures, the control panel in the upper region of the vertical part 9 and the supporting elements in the lower part 8 of the base are clearly visible, in this case in the form of legs set at an angle.

 The operation of the press according to the invention is as follows.

 Figure 1 shows the initial position of the press before starting work. The press is in the folded position and is connected to a power source. The boom 12, rigidly connected to the bar 10, is recessed between the ironing pressure plates. When you turn on the press, the drive mechanism drives the bar 10 and the associated boom 12. On the guide 11 they extend upward.

 The slider 19, revealing the pressing ironing plates 3, when moving downward in the inclined grooves 18 sets in motion the slider 25, which, in turn, moving along the axes 23 through the levers 27, rotates the hinged door 21 to the open position. The hinged doors are returned to the closed position when the sliders 25 are moved along the axes 23 by means of the spring 26 when the slide 19 is moved upward. The press takes on the form shown in figure 2 and figure 3. The heating element placed on the pressing ironing plates is switched on. The inclusion of the heating element can occur at a later stage.

 The drawings show three positions of the rod 10 with the arrow 12. In position III, the waist part of the trousers is fixed on the arrow using the appropriate means placed on it, while the dividing plate 4 should be between the legs. Then the arrow 12 with the rod 10 along the guide 11 is lowered to its original position. In this case, the trousers, passing between the pressing ironing plates 3 and the separation plate 4, exit onto the hinged doors 21 by means of the guide surface 30 and the gripping and straightening means of the lower part of the trousers, for example, falling onto rollers 31, 32, which, rotating towards each other , push the legs on the hinged door 21. The direction of rotation of the rollers 31, 32 is associated with the movement of the boom 12. When lowering the boom 12, the rollers push the legs, and when lifting the boom 12 push them up. The same thing happens if you use an endless belt as a means of gripping and straightening trousers.

 After the trousers exit to the hinged doors 21, the pump feeds liquid from the container through the tubes to the nozzles 29 and the trousers are sprayed. Part of the liquid wets the pants, and the other part, falling on the heated surface of the pressing ironing plate 3, turns into steam. Since at this moment the pressing ironing plates 3 and the hinged doors 21 are closed, the upper part of the trousers (above the trousers) is steamed in the cutout 5 of the dividing plate 4 and between the concave sections 6, since the water that has got on the trousers during spraying turns into steam, as well as ironing the folds on the upper part of the trousers (since they extend beyond the concave sections 6 and fall on the flat part of the pressing ironing plates) and ironing the upper part of the trousers.

 Then, the pressing ironing plates 3 are opened and the boom 12 extends to position I (Fig. 2,3), and after spraying, the pressing ironing plates 3 are again closed. In this position, the next part of the legs is ironed. Next, the cycles are repeated in position II and III of the arrow. After completing the ironing process of the last part of the trousers in position III, the pressing ironing plates are opened and the trousers can be removed from the boom 12. Then, after removing the trousers, the press is automatically folded back to its original position.

The portable automatic trouser press according to the invention has the following advantages:
- provides high-quality ironing of a wide range of trousers along the entire length, eliminating deformation and damage to the fabric;
- has a compact design and, in addition, is simple, convenient and economical to use;
- has simple controls;
- the ironing process is controlled by electronics, which ensures the safety of its work;
- has a low cost.

 The present invention can be used for servicing as a device for household appliances at home, as an ironing press for trousers in hotels, small dry cleaners and other similar objects.
