Definitions

  • the invention concerns a waterproof plastic boot of thermoplastic elastomer, the base of which has a filling with elastically compressible hollow spaces.
  • an absolutely water-tight working boot or thigh boot of elastomer material has been for some time an absolutely essential foot covering, and this type of boot is necessary above all for workers on the land, foresters, builders, road workers, miners, butchers, dairy workers, hunters, fishermen and so on.
  • the invention is based on the principle that it is only possible to overcome these former deficiencies of the completely water and air tight boot if a really effective ventilation of all parts of the foot is obtained, which will make it quite impossible for there to tbe excessive sweating and dampness of the feet. Only by having inside the boot a satisfactory atmosphere for the foot, as far as the moisture content and temperature of the air surrounding the foot is concerned can the above-mentioned foot troubles be removed and their reoccurrence prevented.
  • a layer of air must be provided between the inner sole and the underside of the foot of the wearer, through which the air moved by the pumping arrangement can be distributed to all parts of the foot and so give foot ventilation.
  • Patented sept. 2o, 196e (d) The inner sole and the liner sole must be perforated.
  • the water-tight boot of the invention made of a thermoplastic elastomer, and having a base provided with an insert piece which has elastically compressible hollow spaces or pores, has the particular feature that the Iboot base, at least in the ball-part of the foot, consists of at least iive different layers placed one on top of the other:
  • ll-* a porous sponge rubber layer or layer of air pumping chambers
  • layers III and V two of these layers i.e. layers III and V, being perforated.
  • the ventilation effect is particularly good if the inner sole is perforated and at the bottom of the shaft, on its outer rim, a hollow sole of thermoplastic material is welded on, so as to be water-tight, the hollow space or spaces of this sole being lil-led at least partly with a highly plastic porous sponge rubber, and on the inner surface of the perforated inner sole there being a plastic inner sole of harder plastic, likewise perforated, which has projections on its underside which act as distance spacers.
  • the particular effect of the boot of the invention rests in the five-layer execution of the boot base, at least in the ball-part of the foot, by reason of which the lower four laye-rs form the very powerful air pumping arrangement, setting comparatively large quantities of air in movement, whereas the top liner sole layer, which can be harder than the plastic inner sole and the walking sole, has on its underside sutliciently large ventilation channels which provide even distribution of ventilation over all the parts of the foot.
  • the single figure shows a short shaft of a boot, with the bottom, boot part, in longitudinal section.
  • the shaft l of the -boot is formed in one with the inner sole 1a (forming the layer Ill of the boot base), as is customary with plastic boots.
  • the inner sole 1a forming the layer Ill of the boot base
  • this plastic upper is wel-ded a known hollow, shaped sole 3 of plastic material, with a walking sole layer 1 above which, in a.
  • porous sponge rubber insertion 4 layer ll
  • the hollow space at the back part of the moulded sole 3 is divided up by narrow webs S which rest loosely on the underside of the perforated inner sole of the upper, as the weld join between upper and moulded sole 3 is found made of plastic material which is harder than the plastic material of the uppers 1, 1a and the moulded sole 3.
  • This liner sole has in its sole plate (layer V) a number of perforations 8 and bears on its underside support members or projections 9, acting as distances, which ⁇ are moulded on the sole plate and abut on the softer inner sole 1a at points on the surface which may be localised to a greater or lesser extent.
  • the support members or projections 9 hold open the air distribution layer IV between the inner sole la and the perforated plate of the liner sole 7.
  • the boot of the invention thus has in its base, on which the foot presses, the five above-mentioned layers I-V, layer II in the front part of the boot being a porous air-containing sponge rubber layer 4 and in the rear part of the boot consisting of larger hollow spaces containing fair between the relatively easily deformable webs 5.
  • the projections 9 of the liner sole 7 ensure that the perforations 2 of the inner sole la remain open, so that the air pressed out of the compressed hollow space of the moulded sole 3 reaches the air layer V, and there can flow, in particular where the perforations 8l are not substantially closed by the foot.
  • Water-tight boot of thermoplastic elastomer having a lboot shaft and a boot base, the shaft comprising: an apertured insole formed integrally with the shaft, an apertured liner sole layer located above and distanced from the insole, projections attached to the liner sole and extending between it and the insole to define resiliently compressible chambers between adjacent projections, a walking sole layer located 'below and distanced from the insole, sponge rubber material positioned between the walking sole layer and the insole in the forward region of the boot base, projection located in the rearward region of the boot base and attached to the walking sole layer and extending between it and the insole so as to be in abutting contact with the insole, resiliently compressible chambers each formed fbetween an adjacent pair of these projections; the arrangement being such that during walking air is forced from the second-mentioned charners and the foam rubber material through the apertures in the insole and into the shaft of the 4boot by way of the tirst-mentioned chambers and the apertures in
