Description

The invention relates to a trouser hanger for smoothing treatment of pants or the like with clamping and tension of the hanger edges of the pant legs, with Tensioning means for the trouser legs, steam supply devices and control means for Time and amount of steam and air supply as well as with a waistband and waistband fold tensioning device.

In modern ironing machines, the ironing process essentially takes place by steaming under pressure. The item of clothing to be ironed is preferably from inside out, for a predetermined period of time, live steam is pressed. The items of clothing are placed on a support surface and are through a counter surface held under pressure. This arises in these known devices the disadvantage that there are seams and possibly the trouser pockets, button strips and the like. Visibly and heavily leave marks and may lead to shiny spots. It is also part of the state of the art for ironing devices to be inflatable To arrange sacks within the ironing item (British patent specification 912 853), furthermore Holding device, waistband, spreading and tensioning devices as well as tape holding devices as well as in the crotch area of the trousers.

In a known trouser press (Belgian patent specification 627 695) are also damping and blowing devices for performing a damping and Blowing process provided.

An annular guide flange can be used for blowing into the waistband area (US Pat. No. 2,645,389). In an already proposed ironing press for trousers (German utility model 1882 521), in which a heated upper plate can be pressed onto a stationary, heated lower plate and the plates have recesses in the crotch area, expandable collar bars are arranged in the area of the crotch recess.

An ironing machine is also known (U.S. Patent 1789 638), in which splints are spread along the creases in the trouser legs can.

In another known ironing device (US Pat. No. 1352 158) , electrically heated clamps are provided, between which the trousers are clamped and spread with the aid of a lever device. However, the trousers as a whole are not smoothed out, only the creases are pressed.

In another known trouser press in which the trousers are clamped vertically, machine-fixed spreading devices are provided for the waistband and the cuffs (French patent 1301301).

A trouser hanger machine is also known (U.S. Patent 2 944 710), in which the creases are clamped, and from the inside of the trousers for introducing the creases into the clamping means, additional fold-laying rods are introduced Need to become.

The invention is based on the object of a trouser hanger to create smoothing treatment of trousers, in which the too treating pants over their entire area, including waistband and crotch area can be ironed and can also be used by unskilled workers. The device should also enable a quick succession of ironing operations.

This task is explained in the introduction with the trouser hanger Art according to the invention solved by a combination in that the collar tensioning and bunch tensioning device hang-in or. Is designed insertable that a Suspended and longitudinally tensionable trouser leg spreader is provided that crease clamping devices each from lower and upper clamping strips for each ironing edge of a trouser leg exist and that these terminal strips are arranged one above the other, each the upper terminal strip can be lifted off or swiveled away from the lower terminal strip. By the invention It is possible to use an ironing machine to avoid pressure points at the seams the trouser pockets or the button strips, the ironing or steaming process without pressure, d. H. to be carried out without the application of external pressure, with only that through the fabric Steam penetrating from the inside smooths the fabric. Using the insertable or attachable spreading and tensioning means for the trouser leg ends is the Loading the machine is made easier and faster. The also hang-in or. Insertable waistband and waistband tensioning device allows the trousers to be stretched lengthways the creases and tightening by appropriately clamping the button placket part.

It is particularly advantageous if the crease clamp devices of the two long edges of the trousers horizontally one above the other Are arranged level. This makes it easier to load the trouser hanger.

According to another feature of the invention are the lower and upper Clamping strips can be swiveled laterally by means of expansion devices that can be operated by pressure medium.

Furthermore, the upper terminal strips can be operated by pressure medium Devices can be raised or lowered in parallel with respect to the lower terminal strips be trained.

A useful embodiment of the lowering device consists in Guide rollers and guide curves on the foot parts of the terminal strips for automatic Lifting or lowering depending on the pivoting movement.

To adapt the device to different trouser sizes, it is advantageous to if, according to a further feature of the invention, the two longitudinal edges of the trousers are assigned Clamping devices are freely adjustable to one another in the clamping plane.

To adapt to different fabric thicknesses, it is advantageous to use the Spring tensioning of the clamping strips for elastic mounting.

According to a further embodiment of the invention, the terminal strips consist in the longitudinal direction of individual sections that are independent of each other expandable and each by itself preferably by two springs, screws or the like are.

An advantageous embodiment of the crease clamp device arises when after inserting the pant legs in the front clamping device and the rear clamping device, the respective upper clamping strips by a pressure medium-operated Device in the sense of a spreading movement from the lower terminal strip on one side can be withdrawn.

To stretch the trousers in the longitudinal direction, it is advantageous to have a separate Fastening device on collar end of the terminal strips for the waistband in the form of a cantilevered elastic retaining element, for. B. a clamping spring to be provided.

The ironing process on the trouser leg folds is made much easier and accelerates when steam pipes are between or on the bearing surfaces and clamping strips for the live steam for steaming with outlet openings in the direction of the interspaces are provided between the terminal strips.

To allow the steam to pass easily through the clamping device the upper and lower terminal strips are on their associated sides provided with a scratch coating.

For lifting or lowering the terminal strips are used in machine-fixed Slidable guide curves, guide rollers connected to the cover strips. The postponement the guide rollers is carried out in an advantageous manner by cylinder assemblies that over Ball-guided Bowden cables are connected to the guide pulley carriers. In advantageous Way, guide means are provided on the foot parts of the terminal strips for automatic Lifting or lowering depending on the pivoting movement.

To adapt the clamping devices to different pants sizes the trouser hanger machine according to the invention is preferably designed such that the Clamping devices are adjustable in the trouser transverse direction. This can be on the one hand an adjustment to the width of the trousers to be ironed and on the other hand, too on the cut of these pants. This can advantageously be done by that the clamping device assigned to a trouser length side is fixed to the machine and the clamping device associated with the second lengthwise side of the trousers rotatably on a with the machine frame pivotally connected intermediate carrier arranged floating are.

Since the distance between the support surfaces and the cover strips in the closed State must be kept small in order to achieve a sufficient clamping effect, on the other hand, however, when inserting trousers with different fabric thicknesses, an elastic one It must be ensured that it yields, preferably disc springs for elastic Bracket of the cover strips arranged.

In another embodiment there is a cover strip for one Trouser leg directly with the assigned carrier and the other bar via an elastic Intermediate layer, e.g. B. Rubber pad, tombac metal or the like. Connected to its carrier.

In Fig. 2 are the clamping devices 2, 3 for the pant legs in the shown closed state. There is one by dash-dotted lines inlaid pants 5 indicated. In the leg ends (cuffs) of the pants 5 are end spreaders 6 used, which are attached to pull-out holders 7. The pull-out holders 7 are Slidable in the longitudinal direction, but attached self-locking for adjustment to allow different pant lengths. The pull-out holder 7 can thereby be made from a rubber rope, a spring balancer, a counterweight or the like.

The end spreaders 6 consist, in particular, of the exemplary embodiment according to FIG. 3 emerges from holding pieces 8 and 9, for example in the form of sheet metal plates, the edges of which associated with the creases are designed in a wave-like or jagged shape. A clamping bracket 10 designed as a hook 11 is fastened to these holding pieces 8 and 9. There is also the possibility of forming the end spreader 6 or the parts 8, 9 and 10 in one piece, for example by creating resilient one-piece holding elements instead of the holding pieces 8, 9 by correspondingly bending the clamping bracket 10, as shown in FIG. 3 is indicated by dashed lines. The clamping bracket 10 is shaped in such a way that it forms a hook 11 in its central part. The training can also be made so that instead of a hook 11 a closed eyelet is formed. A separate end spreader is provided for each trouser leg. The end spreaders 6 can also be designed as one-piece wire brackets, which are bent in a V-shape and which are easy to manufacture, with end parts spread out in the manner of a barb.

As shown in FIG. 2, the clamping devices 2 and 3 can be displaced at their rigid ends along guide rods 12 and 13. The design is such that not only a displacement parallel to the longitudinal direction of the machine, but also an inclined position is made possible. For this purpose, the clamping devices 2 and 3 are guided in the waistband area with clamping pieces 14 and 15 on the guide rod 13. In Fig. 2 only the clamping pieces on the waistband side are shown. The design can also be made such that the front-side clamping device 3 is attached at its upper end so as to be immovable but pivotable. The other three end points of the clamping devices 2, 3, however, are guided displaceably in the direction of the movement arrows shown. The pivoting mounting of the clamping devices 2 and 3 on the clamping pieces 14, 15, etc. assigned to them allows the clamping devices 2, 3 to be precisely adapted to the shape of the trousers to be ironed, so that the edges of the hanger for every trouser length, width and shape can always be gripped by the clamping devices to the same extent. A receptacle 16 for a waistband tensioner 16 a can be provided on the guide rod 13. From F .i g. 2 it can be seen that this waistband tensioner consists of a tension rod 17 which can be hooked into slots 18 of the receptacle 16.

In the embodiment according to FIG. 2 consists of the rear clamping device 2 from support surfaces each formed in one piece in the longitudinal extension and Cover strips, while the front clamping device 3 has a different embodiment the cover strips is shown in the form of individual, each movable for itself Parts 24 is formed, two screws 25 are used to fasten each. A detailed description of this embodiment is given below in context with the description of the clamping devices. The F i g. 2 also leaves the handles 26 ', 26 "and 27', 27" for moving the clamping pieces 14 and 15 or for setting up the clamping devices 2 and 3 along the guide rods 12 and 13 recognize.

In Fig. 1 are also two actuating cylinders 28 and schematically 29, the function of which is explained below.

The F i g. 5 and 6 show cross sections through an embodiment the clamping devices 2 or 3. Each is on a machine-fixed carrier 30 is provided on the top of a lower trouser fold support surface 31, which serves to support the crease area of the lower leg. Holding on this crease 32 is caused by a lower clamping strip 33, which is closed State of each lower clamping device over the trouser fold support surface 31 closed come to lie. The covering of these two parts is designed so that the opening diverges between these parts in the direction of the pants. The width of the pants to directed part of the trouser fold support surface 31 is chosen so that even with trouser legs that have a curve in the longitudinal direction, all parts the edge of the bracket always rest sufficiently and be clamped. To the edition of the second, upper trouser leg, an upper trouser fold support surface 34 serves against an upper terminal strip 35 is placed in the closed state.

A pivot cylinder 36 is pivotably arranged on the machine (FIG. 5), the piston 37 of which is fastened via a bolt 38 to a holder 39 for the lower terminal strip 33. This holder 39 carries in its turn a clamping cylinder 40, with the parts 38,39 and 40 pivotally mounted on a pivoting device 41 'on the ironing machine. The clamping cylinder 40 has a piston 41 which is connected to the carrier 42 of the lower clamping strip 33. A carrier 44 for the upper terminal strip 35 is articulated on a second axis 43 which is fixed to the machine. A carrier 45 for the upper trouser fold support surface 34 is connected to the carrier 44. A pivot cylinder 46, which is pivotably mounted in the joint 47 and whose piston 48 is articulated on a holder 49, serves to pivot the device 44 to 49 together with the clamping cylinder 50, with the support 45 for the upper trouser fold support surface 34 on the holder 49 is connected and a carrier 53 for the upper terminal strip 35 is actuated via the piston 51.

This device now works in such a way that by actuating the cylinder 36, 40, 46 and 50 initially separate the individual support surfaces and clamping strips from one another be lifted off and swiveled away, as shown in FIG. 6 is shown. Now a trouser edge is placed on the lower fixed trouser fold support surface 31. By actuating the swivel cylinder 36, 37, the lower clamping strip 33 becomes pivoted to the right and then parallel by actuating the clamping cylinder 40, 41 lowered downward until the one crease 32 is clamped. Now will by actuating the swivel cylinder 46, 48 both the upper trouser fold support surface 34 and the upper terminal strip 35 pivoted to the right. Here comes the upper one Trouser fold support surface 34 to lie just above the lower clamping strip 33. Now the second trouser fold is placed on the upper trouser fold support surface 34, and by subsequent actuation of the upper clamping cylinder 50, 51, the upper Clamping strip 35 lowered parallel to the support 53 until the second trouser leg fold is clamped. This final state is shown in FIG. 5 shown.

In Fig. 7, a modified exemplary embodiment is shown schematically, in which the clamping devices 3 associated with each of the trousers' long sides are arranged fixed to the machine. The clamping devices 2 assigned to the second longitudinal side of the trousers are rotatably connected to their carrier 60 about an axis 61 of an intermediate carrier 62, this intermediate carrier 62 in turn being arranged on the machine frame 1 so as to be pivotable about an axis 63. A spreading cylinder 66 with a piston 67 is provided between the clamping device 3 and the intermediate carrier 62. Here z. B. the piston 67 on an eye 68 of the clamping devices 3 and the expanding cylinder 66 on an eye 70 on the intermediate carrier 62. By this arrangement, the carrier 60 of the z. B. rear clamping devices 2 mounted floating and can be pivoted when inserting a pair of pants to be damped in the respective cut adapted position. After the creases have been clamped in place, the clamping devices 2 and 3 are spread by actuation of the spreading cylinder 66, so that the trousers are stretched transversely to their longitudinal direction in the clamped state.

The in Fig. 8 shown embodiment of the trouser hanger differs from the embodiments according to Fi g. 5 and 6 with regard to the lifting and pivoting mechanism for the upper trouser fold support surface 34 and the upper clamping strip 35. A guide roller 73 is displaceably mounted in a machine-fixed device 71 with a guide curve 72. The guide roller carrier 74 is in turn connected to a holding piece 75 on which a pivotable z. B. ball-bearing Bowden cable 76 attacks. This Bowden cable 76 is pivotably guided in the machine-fixed frame part 30 by means of a pivot ball bearing 77 and, at its other end, is attached to a tension plate 78 of a device shown in FIG. 7 piston 79 shown attached. The piston 79 cooperates with a cylinder 80.

On the other hand, the guide roller carrier 74 is connected to a sliding bush 81 which has a carrier 82 for the lower terminal strip 33 at its upper end. When the piston 79: in FIG. 7 is shifted to the right, the Bowden cable 76 is raised so that the sliding roller 73 in the guide 72 initially passes through the vertically extending branch. As a result, the carrier 82 with the supports 33 and 34 is lifted vertically upwards from the lower support surface 31. The sliding roller 73 then runs through the inclined sloping part of the guide curve 72. As a result, the middle cover strip and support surface are now pivoted to the left together with the upper support surface. From Fig. 7 it can be seen that the arrangement 78, 79, 80 is assigned a similar Bowden cable 83 for the clamping device 2 . A further cylinder 84 with piston 85 and holding plate 86 is provided on the machine frame 1. Two Bowden cables 87 and 88 are also connected to this holding plate 86, of which the Bowden cable 87 is assigned to the clamping device 3 and the Bowden cable 88 is assigned to the clamping device 2. These Bowden cables 87 and 88 act on a further sliding bush, which is connected to the carrier 53 for the upper terminal strip 35. The cylinder-piston arrangement 84, 85 then acts in such a way that the upper clamping strips 35 are additionally lifted from the upper trouser fold support surface 34. The state then reached corresponds to that in FIG. 6 shown relative position of the bearing surfaces and clamping strips. The insertion of a pair of pants is carried out in a similar manner to the previously described embodiment. After a crease has been placed on the lower support surface 31 , the lower clamping bar 33 with the upper clamping bar 34 is pivoted in again by actuation of the cylinder-piston arrangement 79, 80 and then lowered. The second crease is placed on the upper support bar 34 , and the upper clamping bar 35 is pivoted in and then lowered by means of the cylinder-piston arrangement 84, 85. The damping process can now begin. The individual strips are in an end position, as shown in FIG. 5. The actuation of the individual cylinder-piston arrangements takes place, for. B. automatically and is triggered by a foot or hand-operated switch. A two-hand release can also be used to force the operator to initiate the lifting and swiveling movements with both hands, so that injuries and accidents are excluded. The time sequence can either be controlled by a time switch device or determined by operating the associated switching means several times. The ironing process can be facilitated and accelerated by these measures, which are known per se. In Fig. 5, disc springs 64 and 65 are also shown, with which the clamping strips 33 and 35 are fastened to the associated supports 45 and 53, respectively. These disc springs allow the clamping strips to yield elastically in the sense of an enlargement of the space between the clamping strips and the associated bearing surfaces as a function of the fabric thickness of the inserted trouser legs.

Instead of the training according to the embodiment of FIG. 5 and 6 with the elastic disc springs can also, as in FIG. 8 shown schematically, the training can be made so that between the lower support surface 31 and its support 30 on the one hand and between the upper terminal strip 35 and its support 53, an elastic layer 89 or 90 z. B. made of rubber or tombac metal.

The design of the clamping device can be made so that after inserting the trouser legs in the front clamping device 3 and the rear clamping device 2, the respective upper bearing surfaces and clamping strips are lifted on one side together with the aid of the cylinder 29 in the sense of a spreading movement from the lower bearing surfaces and cover strips . The expansion takes place at the cuff-side end of the trouser legs, while the pivot axis is provided at the height of the crotch.

In all embodiments it is achieved that the trouser legs, which are only held on short pieces along the creases, below Effect of the blown live steam inflate, so that by the pressure of the live steam only the trouser legs are straightened from the inside out. After the steaming and drying process, the clamping device for the upper trouser leg is opened again, wherein the terminal strips z. B. be lifted by pressing a foot switch, and the ironed pants can then together with the spreading means for the pant leg ends and the holding device for the collar can be removed from the machine.

The holding device for the waistband and the expansion means for the cuffs are each assigned to a pair of pants, so that the operator during the running Prepare the next pair of trousers or the trousers that have already been ironed during the ironing process can stack. Because of this temporal overlap of the individual operations a particularly high working speed is achieved.

Expediently, an auxiliary support surface 69, which can be raised or lowered by a cylinder 28, is provided under the lower trouser leg in the machine (FIG. 2). In Fig. 9, a separate fastening device is shown schematically and in sections, which are provided at the ends of the clamping devices for the waistband on the waistband. For this purpose, the bearing surfaces 31 are lengthened with respect to the clamping strips 33. A fastening device is provided on the protruding part, which according to the embodiment of FIG. 9 can be designed in the form of a bent clamping spring 91. One end of the clamping spring is bent away from the support surface 31 in order to enable the waistband to be inserted more easily, while the other end is fastened to the support surface 31 or its carrier 30, for example by means of a screw 92.

It is useful to connect the support surfaces and the terminal strips with a to provide known scratch covering. This creates undesirable sliding prevents the pant legs during the insertion process or during the steaming process, and it is achieved that when spreading the pant legs and when inflating by the Live steam cannot slide the creases out of the clamping devices, but to be held immovably without any pressure marks appearing can.

The actuating means for moving the individual cover strips and support surfaces can be professionally modified, it is essential that combine the movements from pivoting and lifting and lowering movements, thereby ensuring is that when closing or opening no shifting of the fabric sides of a hanger edge can take place, which cannot be easily ruled out in the case of a pure pivoting movement is.
