ABSTRACT:
BACKGROUND OF THE INVENTION
Field of the Invention
The present invention relates to an apparatus for pressing shirts, having a shirt-form inflatable body with a flexible enclosure that, in the inflated state, has at least one substantially flat section.
A shirt-pressing apparatus is disclosed in U.S. Pat. No. 3,066,839 to Dosal. The shirt-pressing apparatus described in Dosal has a shirt-form carrying frame around which an elastic inflatable body is positioned. The trunk section of the carrying frame has, on the sides, longitudinal struts that tension the inflatable body in the outward direction in the inflated state and, thus, ensure that the trunk section of the inflatable body assumes the shape of a narrow oval. This design for achieving flattening of the inflatable body has, in particular, the following disadvantages. The width of the inflatable body is predetermined on account of the necessarily fixed configuration of the longitudinal struts of the carrying frame. As a result, shirts of different sizes cannot be fitted equally well onto the inflatable body. Furthermore, the prior art apparatus for pressing shirts, on account of these fixed longitudinal struts, disadvantageously requires a considerable amount of space even when the inflatable body is not inflated. In addition, in this apparatus, the material of the inflatable body is subjected to considerable tensile loading, the loading becoming more pronounced as the flatness of the inflatable body in the inflated state increases. It is, likewise, the case that it is not possible for the front and rear sides of the inflatable body to be flattened to different extents because the longitudinal tensioning in the circumferential direction is substantially constant over the circumference.
SUMMARY OF THE INVENTION
It is accordingly an object of the invention to provide an apparatus for pressing shirts, having a partly flat inflatable body that overcomes the hereinafore-mentioned disadvantages of the heretofore-known devices of this general type and that improves the prior art apparatus to make possible a flattening of at least one section of the inflatable body even in the case of variable expansion of the inflatable body transversely to the flattening, the measures that are necessary for such a purpose are relatively cost-effective and the shirt-pressing apparatus does not require as much space when the inflatable body is not inflated.
With the foregoing and other objects in view, there is provided, in accordance with the invention, an apparatus for pressing shirts, including a shirt-form inflatable body having a flexible enclosure, the flexible enclosure having, in an inflated state of the body, at least one substantially flat section, pulling devices spaced apart from one another and fastened to the flat section at sections within the inflatable body, the pulling devices each having an end, the pulling devices acting substantially perpendicularly on the flat section at which the pulling devices are fastened when the inflatable body is inflated, the sections of the inflatable-body enclosure at which the pulling devices are fastened being retained in a flat form by the pulling devices when the inflatable body is inflated, and a stiff structure disposed within the inflatable body and fastened to the end of the pulling devices.
With the objects of the invention in view, there is also provided an apparatus for pressing shirts, including a shirt-form inflatable body having a flexible enclosure, the flexible enclosure having, in an inflated state of the body, at least one substantially flat section, spaced-apart pulling means fastened to the flat section at sections within the inflatable body, the pulling means having an end, the pulling means acting substantially perpendicularly on the flat section at which the pulling means are fastened when the inflatable body is inflated, the sections of the inflatable-body enclosure at which the pulling means are fastened being retained in a flat form by the pulling means when the inflatable body is inflated, and a stiff structure disposed within the inflatable body and fastened to the end of the pulling means.
Fastened inside the enclosure of the inflatable body, on the sections that are to remain substantially flat even in the inflated state, are pulling devices that subject this section to an inwardly directed force and/or prevent this location of the enclosure of the inflatable body from being forced outward by the internal inflating pressure. This makes it possible to prevent the inflatable-body enclosure from inflating into a round cross-section, and a flat cross-section can be achieved wherever desired. This is advantageous, in particular, in the trunk region of the inflatable body because, as a result of a flat inflatable-body trunk, the shirt is tensioned substantially in the lateral direction and, as such, the shirt can be pressed in a substantially fold-free manner. This process, furthermore, can also be used for the sleeve sections if the sleeves, during pressing, are to be tensioned to give a flat form.
In this embodiment, in accordance with another feature of the invention, it may additionally be provided that the pulling devices are fastened on the structure by fastening devices that can be displaced transversely to the pulling direction. The pulling devices may, thus, follow a movement of the inflatable-body enclosure if the latter, for example, on account of the different forms of the shirts fitted thereon, is moved into different positions. The displaceable fastening devices may be, for example, rings sliding on a rod or abutments sliding in guides.
Those ends of the pulling devices that are located opposite the fastening locations on the inflatable-body enclosure may be fastened on a stiff structure disposed within the inflatable body. It is, thus, possible for nearly random sections of the inflatable-body enclosure to be retained in flat form in the inflated state. The structure located within the inflatable body, here, may be considerably smaller than the inflated inflatable body. As a result, the apparatus only takes up a small amount of space when the apparatus is not being used and the inflatable body has not been inflated.
In accordance with a further feature of the invention, it is also possible for, in each case, two ends of the pulling devices to be fastened on sections of the inflatable-body enclosure. As such, in particular, mutually opposite sections of the inflatable-body enclosure can be pulled together. As a result, the flattening can be achieved without a structure needing to be disposed within the inflatable-body enclosure. Furthermore, it is possible for the desired flattening to be achieved regardless of the position of the interconnected sections of the inflatable-body enclosure and with particularly low outlay. If a plurality of pulling devices is used, it is, thus, possible to achieve a kind of folding-bellows effect. As a result, the inflatable-body enclosure expands specifically in one or two directions as it is inflated. The pulling devices may act on the inflatable-body enclosure at certain points and be disposed, for example, in grid form, it being possible for the pulling devices to be in the form of, for example, cords, rods, or chains, which may be connected to the inflatable-body enclosure, for example, by sewing or buttoning. The pulling devices and inflatable-body enclosure may also be connected by abutments that butt against the inflatable-body enclosure from the outside and are connected to the inner pulling devices. It is also possible, in general, for the pulling devices to be elastic.
In accordance with an added feature of the invention, the pulling devices may be, in particular, pulling strips made of flexible materials. These pulling strips may be fastened on the inflatable-body enclosure along lines. As a result, the tensile force exerted by them, rather than being applied at certain points, is distributed along a line. Furthermore, the pulling strips may be produced, in particular, from the same material as the inflatable-body encl
