Definitions

  • the present invention relates to the ties which control, in inflatable structures such as pneumatic mattresses, the distance between two walls of the inflated structure.
  • ties normally termed height gores, consist of two bands of gummed fabric adhered to each other on a part of their length and connected to each of the mattress walls which are also of gummed or rubberized fabric by the two lip portions formed by the free ends of the bands. It is more economical to replace one of the bands by two hinges or L-section elements, one of the branches of each of which is adhered to the remaining band whereas the other branch constitutes a lip portion connected to the corresponding mattress wall.
  • the object of the invention is to construct the ties of inflatable structures in a more economical manner than in the known arrangements mentioned hereinbefore.
  • the invention provides an inflatable structure wherein the ties comprise one or more threads constituting loops or coils which surround two bands of fabric which are spaced apart and connected to the respective walls of the structure.
  • a further object of the invention is to provide a method for continuously producing a tie comprising continuously unwinding bands, guiding the unwound bands in two spaced paths, continuously winding a thread or thread-like element around the assembly formed by the two bands, and fastening the thread at its points of contact with the bands.
  • the invention also provides a machine for carrying out this method which comprises a rotary thread guide comprising two tubular parts one of which is central and concentric with the axis of rotation of the guide whereas the other is radially offset so as to describe a surface of revolution within which two reels of bands are disposed in such manner that they are capable of rotating about fixed axes and the thread which passes through the central tubular part of the thread guide from a fixed reel can, as it issues from said offset part of the thread guide, be wound round the two bands guided in two spaced paths.
  • the continuous thread which is formed into coils is fastened at its points of contact with the inner bands within the coils by means of two gummed bands which are adapted to be connected to the walls of the inflatable structure and are adhered to the respective inner bands whereby the thread is retained between two bands adhered to each other at diametrically opposed points of the coil.
  • FIG. 1 is a diagrammatic cross sectional view of a pneumatic mattress or inflatable structure according to the invention
  • FIG. 2 is a view in perspective of an embodiment of a thread tie of utility in the mattress shown in FIG. 1;

  • FIG. 13 is a diagrammatic view in perspective of a modification of the machine shown in FIG. 3, and
  • FIG. 14 is a diagrammatic view of another modification of the machine.
  • FIG. 1 illustrates diagrammatically a pneumatic or inflatable mattress comprising two walls 1 ,2 of gummed or rubberized fabric which are interconnected on their periphery by a connecting strip 3 and elsewhere in the direction parallel to the longitudinal edges of the mattress by ties 4.
  • the ties comprise one or more threads or thread-like elements f which extend around two bands 6,7 of gummed or rubberized fabric adhered to the respective walls 1,2 and are put under tension by the inflation of the mattress.
  • the tie thread is a continuous thread wound in the form of a helix around bands 6,7 of gummed or rubberized fabric.
  • the portions 11a, 11b of the coils 11 which extend across the bands are fastened to the latter by complementary bands 12, 13 of gum or rubber which are adhered to the respective bands 6,7 between the coils l1 and to the corresponding wall 1 or 2.
  • the portions 11a, 11b of the thread are thus pinched and retained between the bands 6,12 and 7,13 respectively.
  • FIG. 3 A machine capable of continuously producing a tie such as that shown in FIG. 2 is shown in FIG. 3.
  • a stand 21 supports bearings 22 in which is journalled a hollow horizontal shaft 23 driven in rotation by a motor 24 through pulleys 26, 27 and a belt 28.
  • the latter is in the form of a flail having a radial portion 32 which receives the thread f issuing from the radial aperture 33 and is fixed to the pulley 27.
  • the pulley 27 is integral with the shaft 23.
  • the tubular arm portion 32 is extended at 90 by a tubular portion 34 which extends in a direction parallel to the axis of rotation XX.
  • the thread f issues from the portion 34 by way of the free end 35.
  • On the part 230 of the shaft 23 which extends beyond the radial portion 32 of the thread guide 31 is' suspended by means .of bearings 36 a carriage 37.
  • the carriage comprises a vertically extending plate 38 on which are mounted two spindles 39, 41 carrying rotary reels 42, 43 respectively supplying bands of gummed or rubberized fabric 6, 7.
  • Two series of guide rollers 46, 47 carried by the plate 38 constrain the respective bands to present themselves beyond the end of the shaft part 23a in a position in which the bands are disposed in vertical alignment with each other and symmetrically relative to the axis XX of the shaft 23 so as to be guided horizontally beyond the last rollers 46, 47 in contact with two slide blocks 48, 49 which are integral with the carriage 37 and located within the paths of the bands. The latter are also maintained laterally by side walls 50 FIG. 4).
  • the plate 38 is horizontally offset relative to the bearings 36 mounted on the plate 38 and on a plate 45.
  • a counterweight 51 tends to maintain the plate 38 in a vertical position.
  • the configuration of the plate 38 and its position relative to the shaft 23 are such that the plate 38 and the reels 42, 43 are within a surface of revolution S described by the thread guide 31 so that the thread f issuing at 35 from the guide 31 in a plane P, constituting one of the bases of the surface S, can be wound in the form of a flattened helix around the bands 6,7 supported by the horizontal blocks 48, 49 in contact with which they slide.
  • two reels 56, 57 which are symmetrically disposed relative to the axis XX and supply the two bands l2, 13 of gum or rubber.
  • the latter pass round guide rollers 59, 61 and are thereafter applied against the bands 6,7 between the pinching portions of two pairs of rollers 62, 63 (FIG. so that the thread f wound round the inner bands 6, 7 in the form of coils 11 is trapped between the bands 6, 12 and 7, 13.
  • the rollers 63 are carried by ends of two arms 65 which are pivoted to the stand at their other end 65a and interconnected by a spring 70 which biases the rollers 63 toward the corresponding rollers 62.
  • the pairs of bands assembled with the thread f converge toward the bite or pinching portions of two rollers 64, 66 of a small pressure-applying and driving press device 67.
  • the rollers 64, 66 are driven by a motor 68 and pull on the bands 6, 7 and 12, 13 and unwind the bands from the corresponding reels 42, 43 and 56, 57 and crush the assembly consisting of the two pairs of bands 6-12, 7-13 and the coils of thread 11 interconnecting them.
  • the outer face of the gum bands l2, 13 be covered with a protective film 73 or 74 (FIG. 7) of plastics material, such as polyethylene, which moreover performs the function of a reinforcement for the gum and increases the tensile strength of the bands as they pass through the machine and renders the bands more stable.
  • plastics material such as polyethylene
  • This characteristic is beneficial also in the course of cutting the band 12, 13 from the sheets of gum or rubber due to the fact that the latter are covered with a sheet of plastics material from which the bands 73, 74 are cut.
  • the final flat and flexible product 78 issuing from the machine shown in FIG. 3 has the appearance shown in FIG. 7 where small loops 110 resulting from the crushing of the coils 11,
  • the assembly 78 constitutes a tie ready for immediate use.
  • FIG. 6 shows a device 80 which can be fixed to the plate 38 and to the plate 45 of the carriage 37 for varying the height of the tie.
  • This device comprises mainly a transverse spindle 81 joumalled in the plate 38 and in the plate 45, the portions 81a, 81b of the spindle extending laterally beyond the plate 38 and plate 45 and being screwthreaded in opposite directions and screwed into nuts 82, 83 constituted by bars which are maintained horizontally by transverse guide rods 84 fixed to the carriage 37 and slidably engaged in the end 86 of the bars 82, 83 opposed to the region in which the thread f is wound.
  • a longitudinal rod 88 Fixed to the other end 87 of the bars 82, 83, is a longitudinal rod 88 which extends beyond the plane P in which the thread f is located as it issues from the end 35 of the rotary thread guide 31 before it is wound around the inner bands 6,7, so that the thread is wound around the free ends of the rods 88 and the upper and lower edges 50a, 50b of each side wall 50 in the region of which the bands 6, 7 are guided.
  • the coils 11 are therefore formed along the line N A B M C D N, whose approximate configuration is that of a diamond, and their length, which controls the height of the tie, is a function of the horizontal distance NM between the two longitudinal rods 88.
  • This distance can be modified by screwing or unscrewing the nuts 82, 83 achieved by causing the rotation in one or the other direction of a motor-speed reducer unit 90 whose output shaft rotates the spindle through gears 91, 92.
  • the motor unit 90 of the device 80 for regulating the height of the ties is integral with the carriage 37 located wholly within the surface of revolution S described by the thread guide 31, the unit 90 is supplied with power in accordance with an arrangement, not shown, from contacts sliding on conductive rings integral with the shaft 23.
  • a similar arrangement is also adopted for the connections normally provided for controlling the stoppage of the machine when the reels 42, 43 supplying the inner bands 6, 7 are empty.
  • safety means are provided for stopping the motor 90 when the motor 68 of the press 67 has stopped.
  • a control potentiometer affording a reference voltage to which is compared the voltage of a controlled potentiometer driven by the nuts 82, 83 of the regulating rods 88. Any deviation ascertained results in the starting up of the motor 90 in the required direction. Endof-travel stops are of course provided to limit the travel of the nuts 82, 83.
  • the device 80 To vary the height of the tie along to its length, it possible to program the device 80 by replacing the control potentiometer by an outlet stage of an amplifier controlled by a timing device or by the reading of a perforated card or by the use of a follower in contact with a full-size pattern or model of the profile of the mattress to be produced.
  • the mattress to be shaped at will and in particular enables a mattress (FIG. 8) whose end portions are raised to form a pillow a and a foot rest b to be made. If the mattress comprises tubular or sausage-shaped portions, the edge tubular portions are advantageously bigger so as to stabilize and retain the user of the mattress.
  • the tie can have a constant or, better, a varying height so that the mattress has a quilted appearance.
  • the quilted appearance can be achieved in different ways:
  • the ties of the mattress do not all have the same profile, the elements producing the quilted appearance having a staggered disposition or if it is desired to give a concave shape to the pillow (FIG. 9).
  • the hourly rate of production of the machine shown in FIGS. 3-6 is limited by the speed of rotation of the thread guide 31 which cannot exceed 250 rpm. To in crease the production rate it is necessary to provide multiple windings round the bands 6, 7 of the tie by employing a machine having a plurality of thread guides, such as the machine shown in FIGS. 13 or 14.
  • the machine shown in FIG. 13 comprises two thread guides 31a, 31b which are fixed in diametrically opposed relation on the shaft 23 and so arranged that the outlet 35a, 35b of the respective guides supply two separate threads fa, fb issuing from two fixed reels 29a, 29b.
  • the reel 29a is, in the same way as the reel 29 shown in FIG. 3, outside the rotating part and the reel 29b is mounted on the carriage 38 which carries the band reels 42, 43. Two windings 11a, 11b are thus obtained.
  • the machine shown in FIG. 14 comprises thread guides 31a, 31b, 31c carried by the shaft 23 which supply three threads or thread-like elements fa, fb, fc
  • threads travel inside not only the shaft 23 and the thread guides but also inside three support arms 101a, 101b, 1010 which carry the respective reels and are situated in the plane of the corresponding thread guide. Three windings 11a, 11b, 11c are thus obtained.
  • the thread reel or reels can be mounted on a ring which is driven in rotation and through which the two bands 6, 7 travel, the ring being provided with a plurality of thread guides which correctly wind the thread or threads.
  • the thread guide or guides of the driven ring could, by way of modification, be supplied from one or several hollow rotary reels which are concentric with the ring and through which the two bands 6, 7 also travel.
  • thread or thread-like element f As concerns the filament, thread or thread-like element f, note that it should be relatively elastic, possess zero total torsion and a good stiffness. Moreover, it a should not fray. Good results have been obtained with a 840 denier Nylon thread coated with a plastics resin.
