Definitions

  • the present invention relates to a textile foot-clothing item as classified in the preamble of Claim 1 and to a textile foot-clothing unit according to Claim 27.
  • NBC protective clothing is thus traditionally produced either from completely impermeable systems (suits composed of butyl rubber, for example) or else permeable, adsorptive filtering systems based on activated carbon (powders, fibres or spherocarbon).
  • activated carbon porosity, carbon-powders, fibres or spherocarbon.
  • the air pervious, permeable protective suits generally possess an adsorption layer based on activated carbon which binds the chemical poisons very durably, so that even badly contaminated suits do not pose any danger to the wearer whatsoever.
  • the great advantage of this system is that the activated carbon is accessible on the inside as well as the outside, so that poisons which have succeeded in penetrating at damaged or otherwise nontight locations are very rapidly adsorbed.
  • the prior art solution for this purpose is to protect the feet for military deployment or NBC deployment by using NBC protective overshoes which are pulled over the actual footwear.
  • This has the decisive disadvantage that the footwear has to bear additional weight and, what is more, the wear comfort is drastically reduced by the NBC overshoe.
  • an NBC overshoe does not provide means for efficient sealing joining to an NBC protective suit, so that chemical poisons, warfare agents for example, can penetrate through the transition of NBC overshoes and NBC protective glove and act on the wearer of the NBC protective suit.
  • US 4 843 739 A relates to an adsorption-capable inner shoe material comprising activated car- bon, the activated carbon being in the form of particles which are adhered, by means of an adhesive, dotwise to one side of the inner shoe material.
  • This document does not provide a specific elaboration of the inner shoe material described there as an inner shoe of one-piece construction. Rather, the inner shoe material is to be disposed for example as an intermediate layer between a shoe's upper and liner.
  • NBC protective socks which can for example be worn in conventional military boots.
  • One disadvantage of these NBC protective socks is often the low level of wear comfort, and this can, in particular in the event of physical exertion, for example during military deployments, lead to the foot taking a beating and consequently to blistering and callusing of the skin, particularly in the region of the sole of the foot.
  • the present invention therefore has for its object to provide a textile foot-clothing item and also a textile foot-clothing unit which each provide enhanced wear comfort combined with simple, inexpensive construction and/or a superior barrier function against poisons and/or warfare agents, es- pecially NBC warfare agents.
  • the textile foot-clothing item shall possess in particular good air and water vapour perviousness ("breathability") and use- able in the manner of an inner shoe or in the manner of a sock or stocking.
  • One aspect of the present invention is that the present invention's textile foot-clothing item is formed at least essentially exclusively from a one-piece cut. This leads to simplified, inexpensive production. The reduced number of joins or seams significantly enhances not only the wear comfort but also the protection against poisons and warfare agents, since the present invention's textile foot-clothing item has fewer possible pressure points and fewer possible breakthrough locations for poisons and warfare agents.
  • the one-piece cut comprises a second section, the second section adjoining directly a longitudinal side of the first section and the second section forming a back of the textile foot-clothing item.
  • the result is just one seam along a front region of the first and second sections and along the free longitudinal edges thereof.
  • the seam projects along the region between the sole and the back of the foot (that is to say on the outside surface of the foot); not only the sole region but also the region of the back of the textile foot-clothing item are free of joins or seams, which leads to a distinct improvement in wear comfort.
  • back of the textile foot-clothing item refers to that region of the textile foot-clothing item which, in the wear state, faces the footsole-remote region of the toes of the foot and also the back
  • back of the textile foot-clothing item is thus to be taken as referring to that region of the textile foot-clothing item which when the textile foot-clothing item is being worn covers that part of the foot which is remote from the sole of the foot.
  • sole region is to be understood as referring to that region of the textile foot-clothing item on which, in the wear state, the sole of a foot ac- commodated by the textile foot-clothing item rests; that is, in other words, that region of the textile foot-clothing item which is covered by the sole of a foot in the wear state.
  • front refers to the re- gions of the present invention's textile foot-clothing item, or to be more precise of the cut used in its production, which are oriented towards a forefoot region of a foot accommodated by the textile foot-clothing item, i.e. for example the region of the toes, of the ball of the foot and of the front midfoot.
  • front refers to those regions of the textile foot- clothing item which, in the wear state, are at the front viewed in the direction of motion.
  • rear refers to those regions of the textile foot-clothing item which are oriented towards a rearfoot region of a foot or the ankle or the lower region of a lower leg accommodated by the textile foot-clothing item. It refers, in other words, to those regions which, in the wear state, are at the rear viewed in the direction of motion.
  • join is to be understood as meaning manners of joining in the sector of textile processing which are known as such to one skilled in the art.
  • Nonlimiting examples of methods of joining are sewing, adhering, welding, stapling, tacking and the like.
  • shaft is to be understood as referring to that region of the textile foot-clothing item which, in the wear state, covers, or encloses, the lower leg.
  • inner shoe is herein to be understood as meaning such a foot- clothing item as, in general, is capable of accommodating the foot of a user and of enclosing or covering it on all sides at least essentially completely.
  • the inner shoe can similarly cover a lower section of a lower leg, the section which faces the foot.
  • the textile foot-clothing item can be used as part of a shoe, for example as part of a military boot, or else be worn as a separate foot-clothing item.
  • “Inner shoe” similarly comprehends the elaboration of the foot-clothing item in the manner of a sock, where a relatively short section of the lower leg above the ankle is covered by a shaft of the textile foot- clothing item. It is additionally possible to elaborate the textile foot-clothing item in the manner of a stocking, in which case the shaft of the textile foot- clothing item can cover the length of the lower leg almost completely.

  • Fig. 7 shows a schematic section through a preferred composite construction for the textile sheet material
  • Fig. 8 shows a perspective side view of the textile foot-clothing item in an embodiment comprising a shaft and a finishing band.
  • Figures 1 and 2 show a present invention textile foot-clothing item 1 (in particular in the form of an inner shoe) which preferably provides a protective function against poisons and/or warfare agents, such as NBC warfare agents.
  • the textile foot-clothing item 1 is formed of a cut 2 (depicted in Fig. 6) of a textile sheet material 3.
  • the cut 2 has a first section 4 comprising a sole region 5 and a margin 6 extending beyond the sole region 5.
  • the margin 6 preferably adjoins the sole region 4 on all sides at least essentially. In other words, as Fig. 6 shows, the margin 6 completely encloses the sole region 5's circumference, which is in the plane of the drawing.
  • Figures 1 and 2 and also 6 illustrate that the textile foot-clothing item 1 is preferably formed essentially exclusively of a one-piece cut 2.
  • the one-piece cut 2 and its specific shape result in a present invention textile foot-clothing item 1 (in particular an inner shoe) which has a low number of joins in the sense mentioned at the beginning, in particular a low number of seams, and thus a simple construction. More particularly, the sole region 5 is free of joins and/or overlaps, in particular free of seams, which leads to a significant enhancement of wear comfort.
  • the textile foot-clothing item 1 thus offers high wear comfort while at the same providing a high level of protection against poisons and/or warfare agents, such as NBC warfare agents.
  • Figures 1 , 2 and 6 reveal that the one-piece cut 2 has a second section 7.
  • the second section 7 adjoins directly a longitudinal side 8 of the first section 4 and the second section 7 forms a back 9 of the textile foot-clothing item 1.
  • Fig. 6 further illustrates that the second section 7 directly adjoins the entire longitudinal side 8 of the first section 4.
  • the longitudinal axis 8 - as depicted in Fig. 6 - extends along the longitudinal dimension of the cut 2, so to speak between the first and the second sections 4, 7, that is, along the rear and front regions of the cut 2.
  • the longitudinal axis 8 thus preferably con- statutes at least essentially a central axis of the cut 2.
  • the longitudinal side 8 preferably subdivides the cut 2 into two sections which are equal in area and preferably congruent, namely the first section 4 on the one hand and the second section 7 on the other.
  • first and second sections 4, 7 can be at least essentially symmetrical and in particular mirror-symmetrical to the longitudinal axis 8, in which case the terms "symmetrical” and “mirror-symmetrical” here relate in particular to outer edges and thus to the shape of the first and second sections 4, 7.
  • Minimal departures from the symmetrical shape of cut 2 can be present, in particular in order that the cut 2 may be further conformed to a foot shape and to enhance the wear comfort provided by the textile foot-clothing item 1.
  • cut 2 is simpler to produce. It is thus possible, for example, to produce the cut 2 from a double-ply sheet material 2 having an uninterrupted join at one edge, the longitudinal side 8 then as it were constituting the uninterrupted join of the two-ply textile sheet material 3.
  • the textile sheet material 3 which may be a continuous sheet material for example, can be optimally utilized from a making-up point of view by minimizing the cutting loss.
  • Fig. 6 illustrates the preferred construction for the one-piece cut 2 from which the textile foot-clothing item 1 is produced.
  • the first and second sections 4, 7 have at least essentially the same length Ll and/or the same width B3.
  • the width B3 corresponds at least essentially to half the width B4 of cut 2. It is similarly possible according to the present invention for the first and second sections 4, 7 - as described above - to have the same shape.
  • Fig. 6 further illustrates that one free longitudinal edge 10 of the first section 4 and one free longitudinal edge 11 of the second section 7 may traject at least essentially parallel to each other and/or parallel to the longitudinal side 8. Minimal departures from this parallel trajectory can be present, in particular in order for the cut 2 to be further conformed to a foot shape. It can thus be provided that the free longitudinal edges 10, 11 at least minimally approach each other in the direction of the rear region of cut 2.
  • Fig. 6 further shows that the second section 7 of cut 2 has at least one longitudinal incision 12.
  • the longitudinal incision 12 trajects preferably at least essentially parallel to the longitudinal side 8. Furthermore, the longitudinal incision 12 preferably trajects at least essentially in the centre of the second section 7.
  • the longitudinal incision 12 may extend to a rear transverse edge 15 of the second section 7, as can be seen in Fig. 6.
  • the rear transverse edge 15 so to speak forms the rear conclusion of cut 2.
  • the longitudinal incision 12 starts at the rear transverse edge 15 and trajects transversely, preferably at least essentially perpendicularly, to the rear transverse edge 15.
  • the length L3 of the longitudinal incision 12 according to the present invention is not more than 75 %, especially not more than 70 %, preferably not more than 65 %, more preferably not more than 60 %, even more preferably not more than 55 % and most preferably not more than 50 % of the length Ll of the second section 7.
  • the second section 7 has a transverse incision 13.
  • the transverse incision 13 can traject transversely, preferably at least essentially perpendicularly, to the longitudinal incision 12. It is preferable according to the present invention when the transverse incision 13 trajects through an end point of the longitudinal incision 12.
  • the longitudinal incision 12 and the transverse incision 13 are disposed such that they form a T-shape at least essentially.
  • the longitudinal incision 12 halves the transverse incision 13, i.e. the end point of the longitudinal incision 12 is at least essentially in the middle of transverse incision 13.
  • the length L4 of the transverse incision 13 is not more than 75 %, especially not more than 70 %, preferably not more than 65 %, more preferably not more than 60 %, even more preferably not more than 55 % and most preferably not more than 50 % of the width B3 of the second section 7. It is preferable according to the present invention when the length L4 of the transverse incision 13 is less than the length of L3 of the longitudinal incision 12.
  • Fig. 6 shows that the longitudinal incision 12 and the transverse incision 13 subdivide the second section such that preferably two flaps 14 result in its rear region, and they will be more particularly described hereinbelow.
  • the longitudinal incision 12 and/or the transverse incision 13 form an opening 22 through which the foot is accommodated in the textile foot-clothing item 1.
  • first section 4 comprises a front first marginal section 6' and/or the second section 7 comprises a front second marginal section 6".
  • the front first marginal section 6' and/or the front second marginal section 6" preferably have an arcuate trajectory in the sense mentioned at the beginning.
  • the arcuate trajectory of the first and/or second front marginal sections 6', 6" may be at least essentially conformed to the shape of the toes and/or of the forefoot, in particular against the background of optimally conforming the textile foot-clothing item 1 to the user's foot shape.
  • the front first marginal section 6' and the second marginal section 6" may have essentially an identical trajectory and/or at least essentially an identical shape, it being in accordance with the present invention to have an equal-in-area and preferably at least essentially mirror-symmetrical configuration for the front first and second marginal sections 6', 6".
  • the width B 1 of the front first marginal section 6' along the sole region 5 may be at least essentially not more than one third, preferably not more than one quarter, more preferably not more than one fifth and more preferably not more than one tenth of the maximum width B2 of the sole region 5.
  • the with B 1 can vary along the front first marginal section 6'.
  • the textile foot- clothing item 1 can also be conformed to the foot shape and/or foot size via the choice of the length L2 and of the width B2 for the sole region 5 or to be more precise of the length Ll for the cut 2.
  • an uninterrupted first join 17 in the sense mentioned at the beginning can join the front first marginal section 6' and the front second marginal section 6" together.
  • the first join 17 can extend further along the free longitudinal edges 10, 1 1.
  • the first join 17 simultaneously extends along the front marginal sections 6', 6" and the free longitudinal edges 10, 11.

This is because, owing to the small number of joins and their specific arrangement, the present invention has succeeded in minimizing the number of possible pressure points and potential break- through locations for warfare agents and/or poisons.
  • the foot-clothing item according to the present invention and its production are distinctly simplified and therefore remarkably inexpensive.
  • the textile foot-clothing item or unit has excellent air and water vapour per- viousness and thus a high level of breathability, additionally improving the wear comfort.
  • Moisture, especially in the form of perspiration, can be effectively conducted away from the foot even under high physical exertion. This effect is effectively supported by the high level of air perviousness. This keeps the skin pleasantly dry even under severe exertion, so that the skin does not, in particular, go all soggy.
  • the aforementioned properties make the present invention's textile foot-clothing item and the present invention's textile foot-clothing unit especially useful for military deployment or NBC deployment (for example in the form of a military inner shoe or a military sock or stocking).
  • the high efficiency of the protective function provided by the present in- vention's foot-clothing item and by the present invention's foot-clothing unit makes it possible to use breathable materials, such as leather for example, in relation to the shoes to be worn, so that the wear comfort can be still further enhanced in this way without the wearer of the present invention's foot-clothing item or of the present invention's foot-clothing unit being ex- posed to an elevated risk due to the use of a breathable shoe material.
  • the present invention's foot-clothing item and the present invention's foot-clothing unit may be produced in a conventional manner. This will be very well known to one skilled in the art of manufacturing foot-clothing items, in particular inner shoes, socks or stockings.
  • the present invention's foot-clothing item or the present invention's foot-clothing unit may be produced by first preparing a cut, especially as described above, from a textile sheet material, in particular as described above, and joining this cut together by means of joins, in particular as described above, such that a second section of the cut forms a back for the textile foot-clothing item.
  • the join is effected such that a sole region of the textile foot-clothing item is free of joins and/or overlaps, in particular free of seams.
  • the textile sheet material may be im- pinged with an adsorbent for poisons and/or warfare agents, in particular with an adsorbent as described above, to further enhance the protective effect against poisons and/or warfare agents.
