Definitions

  • the air-cushion sock constituting the subjectmatter thereof comprises two relatively thin superposed sheets of p.v.c. or other suitable heat-weldable resin materials, these sheets being die-cut to the desired shape and welded along their edges to form the afore said separate compartments each containing a sufficient quantity of air.
  • These two thin superposed sheets of resin material may be obtained from two separate webs or from a single but tubular piece of extruded material; in the last case the transverse weld seams assembling the two sheets may be formed directly during the extrusion process.
  • Flat sheets may be used as such; in certain cases, one or both of a pair of thin, air-impervious sheets may be heat-shaped in such a manner that each compartment may have the same thickness along its edge and in it central portion.
  • means may be implemented for causing the air pressure to differ from one compartment to another, so that each compartment be inflated at the pressure best suited to the weight to be supported during the actual use of the sock.
  • This result may be obtained directly from the welding operation by simply causing these two sheets to adhere, for example by suction, to patterns or forms having the desired contour, except ofcourse along the weld seams; thus by properly selecting the curvature of these patterns or forms, it is possible to, adjust with a high degree of precision the pressure values obtained in the various compartments.
  • FIG. 1 is a perspective view of a sock
  • FIG-S. 2, 3 and 4 are longitudinal sections showing FIG. 9 is a plane view showing a modified form of embodiment of one of the sheets constituting a sock according to this invention.
  • FIGS. 10 and I] are sections taken along the lines X-X and XXl of FIG. 9, respectively.
  • FIG. 12 is a fragmentary perspective view showing on a larger scale the sock illustrated in the preceding FIGS. 9 and 10.
  • the sock shown in the various figures of the drawing comprises essentially two relatively thin sheets 1, 2 of a flexible, air-impervious material, such as p.v.c., these sheets being welded along their peripheral edge 3 and also along transverse lines 4, 5, 6 and 7 to form air-tight compartments 8, 9, 10, 11 and 12 filled with air so as to have a certain thickness.
  • the quantity of air contained in each compartment may differ, according to the weight to be supported thereby and also to the particular contour of the wearers foot.
  • the flexible and airimpervious envelope constituting the sock according to this invention may be obtained from a tubular blank or web 13 in which the compartments are formed either by means of the transverse weld seams or lines 4 to 7, as in the preceding case, or by means of integral joints 14, 15, 16 and 17 formed directly during the extrusion process.
  • these sheets 1 and 2 of flexible, airimpervious material may be lined with a relatively thin sheet of foam l8, 19 in which air is retained (closedcell foam structure), as shown in FIG. 5.
  • these two sheets are welded together along their edges and also along transverse lines 20, unless these transverse lines are obtained directly by extrusion in the form of a small partition 21 interconnecting the sheets.
  • the sock may be reinforced by providing a stiff edge 22 along the more strained side, that is, as a rule, the outer side.
  • the sheets of thin flexible, airimpervious material may be heat-shaped to comprises a number of separate longitudinal compartments 24 between which a double partition 25, 26 is formed to an inverted U configuration, as shown, in the case of the lower sheet, and comprises a marginal flange 27 coplamar with the top or upper face 28 of these double partitions 25, 26; small passages 29 may be provided in the partitions to permit the flow of air from one compartment to another with a sufficient throttling effect.
  • a longitudinal partition may also be provided, if desired, this longitudinal partion consisting similarly of two sheets 30 and 31, with a top face 32 level with the other top faces 28 of the aforesaid transverse partitions and also with the flange 27 of the sock; this longitudinal partition may also comprise small throttling passages 33 interconnecting a pair of transversely aligned compartments.
  • the assembly is closed and sealed by simply superposting thereto a thin sheet 34 of flexible and air-tight material welded along the flanges 27 of the sock and also to the top faces 28 and 32 of the transverse partitions and possibly of the longitudinal partition.
  • a sock of the type set forth by completing same with another inner sole adapted on the one hand to isolate the wearers foot from the flexible and air-tight material constituting said sock, an on the other hand to'ensure a better distribution of the foot pressure over the entire surface of the sock; thus, an inner sole of the type described and illustrated in the French Pat. No. 1.426.837 of its Certificate of Addition No. 91.180 may advantageously be used, this second sole being cemented to, or simply laid on the first one.
  • a sock comprising a thin envelope of flexible, airimpervious material, divided longitudinally into a plurality of internal fluid-tight compartments of relatively large dimensions, each compartment containing air and forming an air cushion, said envelope being sized to extend beneath the full length of a foot with each compartment producing an individual damping action when aload is applied thereto, a different air pressure being obtained in each one of said compartments in order better to adapt each of them to the load to be applied thereto.
