Garment pressing devices take many shapes and forms. One category of garment pressing devices includes devices for ironing shirts, blouses and similar articles of clothing. Typically, shirt-pressing devices include a shirt mannequin or form, conventionally referred to as a buck. The buck has the form of a shirt wearer with front, back and opposing lateral sides therebetween on which a shirt or blouse or similar garment, referred to hereinafter as a shirt, is placed and fitted. Many bucks have shirt shoulder rods that are extended outward from the opposing lateral sides of the buck to support the shoulders of a shirt in proper orientation during an ironing operation and are connected to air bags that are moved outward into an inflated or extended position from the opposing sides of the buck by the extension of the shoulder rods, which are movable between extended and retracted positions, the shoulder rods being attached to the air bags by, for example, a spring and/or a tether to expand the shirt body during operation of the garment pressing device. In normal operation of the garment-pressing device, the shoulder rods are retracted, as are the side air bags to permit an ironed shirt to be easily removed from the buck and to facilitate placement of a shirt on the buck prior to being pressed.
Typically, these garment pressing devices include a fan or blower for blowing room air, which may be filtered, to facilitate drying of the shirt and to inflate the aforementioned air bags to expand shirts whose widths are larger than the width of the buck during operation of the garment pressing device. The air may be heated, if desired, using a conventional air heater. Also, the air can be blown into the sleeves of the shirt to inflate and dry the sleeves while the body of the shirt is pressed using heated plates or platens that are movable toward and away from a shirt on the buck.
Some shirt pressers operate using pneumatic controls that employ compressed air provided by an air compressor, with heated platens being moved relative to the buck using conventional pneumatic circuits and controls. Semi-automatic operation is typical, providing control over the relative movement between the buck and the platens to an operator using suitable controls, e.g., foot pedals and hand controller switches and levers. Such circuits and controls may include, for example, air pumps, air compressors, electrical and pneumatic motors, pump controls, motor controls, pneumatic circuits, electrical and electronic circuits, pneumatic controller(s) and electrical/electronic controller(s).
Prior art shirt-pressing devices may employ inflatable side air bags that are designed to permit ironing of shirt bodies of different sizes, including shirts that are larger in width and diameter than the width and diameter of the buck. However, such devices still have problems in producing acceptably ironed shirts. For example, operation of prior art shirt-pressing devices occasionally result in pressed shirts having areas which are not properly pressed. For example, shirt seams where shirt sleeves join the shirt body often are not properly pressed. These seams, when pressed, may have undesired creases, or these seams may not be fully pressed. Moreover, portions of the shirt sleeves and/or shirt body adjacent to these seams often have creases or are not fully pressed, and/or the seams and sleeves and adjacent shirt body may have a puckered appearance after being pressed. Some of these problems are attributable to the differing sizes of shirts, especially large sized shirts, not being properly smoothed by prior art shirt pressing devices prior to being pressed.
The apparatus, systems and methods of this invention attempt to reduce occurrences of the aforementioned, and similar, problems by providing shirt pressing devices which employ expandable and retractable shirt pressing buck shoulder expanders, platen extensions, and air bag extenders.
While the shoulder expanders may work independently of, or in conjunction with, the air bag extenders, various exemplary embodiments of the apparatus, systems and methods of this invention employ a combined stage shoulder expander and air bag extender.
In various exemplary embodiments of the apparatus, systems and methods of this invention, a single-stage movement operation shoulder expander and air bag extender is provided.
In various other exemplary embodiments of the apparatus, systems and methods of this invention, a multiple-stage movement operation shoulder expander and air bag extender are provided.
In various exemplary embodiments of the systems, apparatus and methods of the invention, expanded/extended heating platens are provided. In various exemplary embodiments, platen extensions or expanded portions may be curved differently than the curvature of the main body of the platens and may lie in a plane that is at an angle to the plane in which the main body a platen lies. For example, a platen extension may extend from the main body of the platen in a direction away from the buck on which a shirt is placed to be pressed. In any event, even though the platen extensions may have the same curvature as the main body of the platen, Applicant has found that improved pressing properties are achieved when the platen extensions slope away from the buck so that the surfaces of the heating platen extensions are not parallel to the surfaces of the platens and are not parallel to the surfaces of the buck. In various exemplary embodiments, the platen shoulder extensions have a curved, e.g., arcuate, cross sectional shape in end view. This platen extension shapes work in unison with various exemplary embodiments of the shoulder expanders to result in improved pressing of shirts.
Various exemplary embodiments of shirt expanders according to this invention have several components. In the single inflatable expander element embodiments, a single, movable, expander frame is provided. In the multiple inflatable expanded element embodiments, two or more separate, nested expander frames are involved.
In various exemplary embodiments, the shoulder expanders include one or more inflatable chambers.
In various other exemplary embodiments, the shoulder expander support element has a layered structure of flexible material.
In various exemplary embodiments of the apparatus, systems and methods of the invention, the movable shoulder expanders have one of more movable support frames. Each movable support frame has a U-shaped cross-section. In various exemplary embodiments of the invention, pneumatic circuits made up of air compressor(s), hoses, valves, pistons high pressure are employed to operate the garment-pressing device. These pneumatic circuits may be operated manually, or have control circuitry to be operated semi-automatically.
One object of the invention is to provide an expandably and retractably mounted shoulder/sleeve expansion support mechanism that includes expandable side air bags to result in ironing of shirts and blouses of differing widths in an effective manner, i.e., in a manner that reduces the occurrence of puckered fabric and/or fabric creasing pressed/ironed into the shirts and blouses.
Another object of the invention is to provide an arcuate platen expansion extension which is set at an angle to the plane of the front heated platen of a buck type shirt press to accommodate the expansion of the shirt shoulder/sleeve area caused by the aforementioned shoulder/shirt expansion support mechanism, so that the occurrence of puckered fabric and or fabric creasing pressed/ironed into the shirt or blouse is reduced.
Another object of the invention is to provide systems, apparatus and methods for reducing creasing and/or puckering in the shoulder and sleeve portions of shirts and/or blouses ironed by buck-style shirt/blouse presses/ironers.
Another object of the invention is to provide systems, apparatus and methods for reducing creasing and/or puckering in shirts of different sizes ironed by buck-style shirt/blouse presses/ironers.
Another object of the invention is to provide continuously and/or incrementally adjustable buck-style ironing systems, apparatus and methods for reducing creasing and/or puckering in shirt of different sizes.
Another object of the invention is to provide modified shirt/blouse buck-type press/ironers that reduce creasing and/or puckering in shirts of different sizes, and which have operating system components including pneumatic drive systems.

FIGS. 3B1-3B3 are perspective views of a platen having a shoulder expanded platen element;
In this exemplary embodiment of the invention, the buck 200 includes a shoulder rod 201, which is connected via a spring 211 and tether 212 to a side air bag 203. The buck 200 also includes a shoulder extender 130, which movably extends from the shoulder portion of the buck 200 to expand the surface area of the buck 200 in the shoulder area of the buck 200. The platen assembly 300 has a front platen 310 and a rear platen 320, and is provided with front and rear platen shoulder extensions 311 and 321.
In operation, the buck 200 and the platen assembly 300, which are movable with respect to one another, are moved to coincide so that the buck 200 fits between the front platen 310 and back platens 320 of the platen assembly 300. The platen assembly 300 is moved to come in contact with, and press a garment, e.g., shirt, 1 mounted on the buck 200. Then the platens 310 and 320 are withdrawn away from the buck 200 and the platen assembly is moved relative to the buck so that the buck 200 and platen assembly 300 are no longer aligned with one another but are separated from one another in a sideways direction. This permits a user to remove the pressed shirt and mount another shirt on the buck 200 for pressing by the platen assembly 300.
In the exemplary embodiment of the buck 200 shown in
This shape is similar to the shape of the shoulder extender airbag embodiment shown in
In this exemplary embodiment of the invention, each of the shoulder extenders 130 includes two airbags 133 and 134. The airbags 133 and 134 are mounted adjacent to one another at each end of the rigid frame 1302 and adjacent main layers of material. In various exemplary embodiments of the invention, the layer of material 1303 that is adjacent to rigid frame 1302 is an approximately ⅜ inch thick piece of silicone rubber, but may be made of any suitable resilient material with similar characteristics and suitable thickness. In various exemplary embodiments, the next layer, i.e., layer 1304 adjacent to the resilient layer 1303, may be made of a ¼ inch thick cotton pad, but may be made of any suitable backing material to cushion the pressing platens and to which an inflatable shoulder extender casing may be attached, e.g., by sewing or by pinning. Next to cotton pad 1304 is a thin layer of cotton fabric, which also covers flaps of the shoulder airbag 133.
In
In this exemplary embodiment of an expander element 130, a relatively thick, e.g., ¼-⅜ inch thick, cotton pad 1304 contacts a relatively thick, e.g., ⅜ inch thick, silicone rubber pad 1303. Pad 1303 contacts a rigid support plate 1302 made, for example, from a plastic such as, for example polymethylmethacrylate (PMMA), or a rigid metal. On the other side of the rigid support plate 1302 are shoulder expander frames 131, 132. Flaps 1334 of the air bags are used to attach the air bags 133, 134 to the shoulder expander frame 131 and the cotton pad 1304 and rigid frame 1302.
Actual dimensions of one actual exemplary embodiment of the inventions are listed in Table 1.
Operation of the two-stage expander mechanism exemplary embodiment shown in
The left side first cylinder 1090 is operated to extend first cylinder shaft 1090S and piston 1090P a distance x to the left. This results in the following sequences of events:
(1) Because the first cylinder piston 1090P is fixedly connected to the first expander frame drive shaft 1080 by connector B3, the first expander 132 is extended a distance x to the left, i.e., outward and away from the center of the buck 200.
(2) Because the first cylinder piston 1090P is also fixedly connected to second cylinder drive shaft 1070S by connector B3, both the second cylinder 1070 and the second cylinder drive shaft 1070S are moved a distance x to the left, i.e., outward and away from the center of the buck 200 to the left.
(3) Because the second cylinder piston 1070P is fixed to the second expander 131 via center drive shaft 1060 (which is fastened at one end to the second expander 131), the second expander drive shaft 1060 and the second expander 131 are moved a distance x to the left, i.e., outward and away from the center of the buck 200 to the left.
(4) Because second expander drive shaft 1060 is fixedly connected to a shoulder rod cylinder 1050 by connector B1, the shoulder rod cylinder 1050 is moved a distance x to the left, i.e., outward and away from the center of the buck 200 to the left.
The movement of the second stage is similar to that of the first stage and can be more fully understood from the drawing Figures.
In a single-stage expander embodiment, as shown, for example, in
In a continuous displacement single expander frame embodiment, as shown, for example, in
It should be appreciated that the shape of pistons used to move the shoulder expander mechanisms can vary and can include rectangular, cylindrical, annular or other suitable shapes.
It should also be appreciated that any suitable material can be used to form the shoulder expander frames including, for example, plastics, metals, rubbers, composites, and laminates. Moreover, shoulder expanders may include padding such as folded cotton layers, folded felt payers, folded rubber sheets, etc.
It should also be understood that the shoulder extenders may be operated not only pneumatically, electrically or electromechanically, but also just mechanically.
Various other modifications may be made to the systems and methods according to the invention that are within the scope of the claims.
