Definitions

  • a pants press has two press plates each having a rigid 219 25 541 530 533; 3 1 17 775 base plate and a pressure plate connected thereto.
  • a 7733 89; 100/93 p heating element is interposed between the two latter 1 plates and a heat insulator is provided between the [56] Ref ren e Ci d heating element and the base plate.
  • the present invention relates to apparatus for ironing articles of apparel and, more particularly, to apparatus for ironing of trousersand slacks.
  • the present invention for a heated press comprises two press plates movable relative to each other between an open rest position and a closed working position and adapted to receive between themselves in the open position an article to be pressed in said closed position of said press plates.
  • At least one of said press plates comprises a rigid base plate, and a pressure plate substantially coextensive with said base plate and connected thereto.
  • Heating means for generating heat between said base and pressure plates is provided.
  • Heat insulating means is provided between said heating means and said base plate to prevent the loss of heat through the latter, said base and pressure plates being arranged so that when the press is closed, said pressure plate is in contact with the article to be pressed.
  • both press plates are similarly constructed. Also,
  • said heating means comprises an electrically isolating mounting layer, and a resistive heating layer.
  • Said resistive heating layer has two opposite edges, further comprising two-electrical conductors each connected to another of said opposite edges to provide good electrical conduction therebetween.
  • Each electrical conductor is arranged to be connected to another terminal of a source of electrical energy to thereby cause current to flow through said resistive heating layer from one edge thereof to the other and causing the same to become heated.
  • said electrical conductors are connected to said resistive heating layer by a zig-zag sewing stitch.
  • suitable heat reflecting means and electrical isolating means are provided to prevent electrical shocks to the user as well as to preserve the heat generated and to direct the latter away from the base plate and towards the pressure plate.
  • FIG. 1 is a fragmented cross sectional view of a press plate in accordance with the present invention, shown exploded for facilitating the description thereof;
  • FIGS. 2-5 are fragmented cross sectional views similar to that in FIG. 1, showing modifications of the arrangement shown in FIG. 1;
  • FIG. 6 is a front elevational view of the heating element as shown in FIG. 1.
  • FIG. 1 shows a heated press plate, in its exploded fragmented view, in accordance with the present invention.
  • the press plate comprises a rigid base plate 13, for example, a gripping or clamping plate, the base plate having an outer periphery in the form of a rim 15 which is provided with screw holes 17 which are spaced from one another along the periphery.
  • FIGS. 1-5 In order to facilitate the description of the press plates in accordance with the present invention, namely the press plates as shown in FIGS. 1-5, these have been shown in their exploded views. However, in the assembled state of the press plates, the various layers which are shown in the Figures are in intimate contact with one another. To obtain such intimate contact, a pressure plate 20 is provided about its periphery with screws 21 which are positioned to correspond with the screw holes 17. In the assembled state, the screws are screwed into the screw holes and the two exterior 'plates are'in this manner drawn together in pressure contact relationship.
  • a heat insulating plate 24 Placed adjacent to the base plate 13 is a heat insulating plate 24 which advantageously can withstand temperatures over C.
  • a heat resistant material can, for example, consist of polystyrene foam material or known materials such as asbestos.
  • One important function of the heat insulator 24 is to prevent heat loss in the direction of the base plate 13 while electrically isolating the base plate against any electrical voltages which may appear on an electrical resistance heating element, generally designated by the reference numeral
  • the heating element 28 is shown in FIG. 1 to consist of an electrically isolating mounting layer 29, e.g., from paper, and an electrically conductive heating layer 30.
  • the total thickness of the heating element 28 is, as. presently contemplated by the present embodiment, from 0.2 to 0.25 millimeters.
  • the contemplated dimensions for the resistance heating element 28 are approximately 35 by 55 centimeters.
  • the heating element 28 is connectable to a source of A. C. voltage and when driven by a 220 volt line voltage, the power consumption or disspation in the heating element is approximately 180 watts.
  • connectors 35 which, in accordance with the presently described embodiment, are made from copper foil.
  • the connectors 35 are connected to the resistive heating layer 30 by means of a zig-zag sewn stitch 37.
  • the connection is such as to insure good electrical conduction between the connectors 35 and the electrical conductor or resistive heating layer 30.
  • Each of the connectors at opposite ends of the resistive heating layer 30 is connectable with one pole of a driving source of voltage through conductors, e.g., 39.
  • the connectors 35 are typically 0.15 millimeters thick.
  • FIG. 1 shows, as noted above the layers of the layered construction of the press plate.
  • the electrical safety to the user against shocks is guaranteed with the present construction, particularly when the base plate 13 and/or the heat insulator 24 and/or the pressure plate are additionally electrically isolating.
  • the base plate 13 is isolated from electrical voltages by the heat insulator 24, which in this embodiment is also selected to be electrically isolating.
  • the pressure plate 20 is isolated from the electrical voltage by the provision of the mounting layer 29 which has been described to be made from an electrically isolating material such as paper.
  • FIG. 2 Another embodiment is illustrated in FIG. 2 wherein the same reference numerals representing similar parts have been kept identical to those utilized in FIG. 1.
  • the arrangement here shown is substantially similar to the basic arrangement except that the heating element 28 has been reversed so that the resistive heating layer 3.0 now faces the left as seen in the Figures as opposed to facing to the right in FIG. 1. Accordingly, the mounting layer 29 now-appears on the right-hand side, or facing the base plate 13. Because the electrically isolating mounting layer 29 is no longer provided adjacent to the pressure plate 20 for preventing the appearance of electrical voltages thereon, an additional electrical isolator must now be provided. In accordance with the embodiment shown in FIG.
  • a layer 40 is provided on the pressure plate 20, e.g., such as a coat of paint, a covering or any other electrically isolating material.
  • the embodiment as shown in FIG. 3 utilizes, instead of a coat of isolating material'deposited directly on the pressure plate 20, an intermediate layer 43 which is, similarly electrically isolating.
  • the intermediate layer 43 can advantageously be made from polyethyleneterephtalate.
  • a heat reflecting surface 45 made, for example, from a metal foil, e.g., from aluminum foil, is interposed between the heat insulator 24 and the heating element 28. It will be appreciated that with this arrangement, any heat energy which is directed in the direction of the base plate 13 will be reflected by the metal foil 45 in the direction of the pressure plate 20 where it can be best utilized. However, when an arrangement as illustrated in FIG. 4 is utilized, there exists the possibility that voltages which may be transmitted from the resistive heating layer 30 to the metal foil 45 may cause an electrical shock to the user. It is advantageous to add a heat resistant electrically isolating foil 47 to separate the resistive heating layer 30 and the metal foil 45. The electrically isolating layer 47 may be made from any suitable material which is commonly used for such purposes.
  • FIG. 6 which I has already been discussed above, clearly shows the zig-zag sewing stitch 37 which is utilized to produce an electrically conductive connection between the metal foil strip 35 and the resistive heating layer 30.
  • press plates as described above be utilized in an apparatus for ironing articles of apparel as disclosed in the applicants US. Pat. No. 3,491,469. As disclosed in this patent, it is contemplated that either one or both press plates be constructed in the fashion described.
  • a heated press particularly'for pressing articles of clothing, comprising two press plates movable relative to each other between an open and a closed position and adapted to receive between them in said open position an article to be pressed in said closed position, at least one of said press plates including a rigid base plate, a pressure plate substantially co-extensive with said base plate and connected thereto, heating means comprising an electrically insulating mounting layer and a resistive heating layer arranged between said base plate and said pressure plate, and heat insulating means intermediate said heating means and said base plate for preventing loss of heat through the latter, said base plate and said pressure plate being arranged in such a manner that said pressure plate contacts the article tobe pressed when said press plates are in said closed position, said resistive heating layer having two opposite edges and further comprising two electrical conductors each connected to' another of said opposite edges in electrically conductive relationship, each electrical conductor comprising an elongated metal foil strip and being arranged to be connected
  • a heated press as defined in claim 8, wherein said electrically isolating means comprises an intermediate layer interposed between said side of said pressure plate and said heating means.
