Definitions

  • a sleeping bag comprises two bags which can be put into and withdrawn and detached from one another and whose through stitchings are relatively offset, the bags when inserted one into the other being so tightly interconnected that an insulating air volume is enclosed between the two bags.
  • This invention relates to a sleeping bag for use at either relatively low or higher ambient temperatures, said sleeping bag comprising two bags which both are double-walled and have an intermediary filling of down or other suitable material, and suitably spaced apart through stitchings for keeping the filling in position.
  • a sleeping bag for camping purposes can be relatively simple and cheap.
  • the stitchings necessary at suitable intervals for keeping the filling of the sleeping bag in position can very well be effected as through stitchings, which is not possible in sleeping lbags for more exacting conditions since such through stitching will result in that the cold penetrates into the interior of the sleeping bag.
  • the filling of such a sleeping bag can thus be made no matter how Warm and substantial and the sleeping bag in its entirety still will not be sufficiently warm.
  • This invention thus relates to a sleeping bag which pro vides a solution of the problems outlined above.
  • Characteristic of the sleeping bag is that the two bags can be inserted one into the other or be withdrawn and detached from one another in dependence on the external conditions, and when inserted one into the other the two bags can be detachably interconnected at the respective opening edges of the two bags in such a tight manner that an insulating air volume is enclosed in the space between the two bags, and the through stitchings of the assembled bags are spaced the same distances apart but offset for preventing the cold from penetrating into the interior of the sleeping bag.
  • connection between the two bags is realized by way of zip fastener, so-called bur fastener or other similar continuous and substantially tight closure.
  • FIG. 1 is a view of the outer bag
  • FIG. 2 is a view of the inner bag
  • FIG. 3 is a view of the two bags in an assembled state, the inner bag being indicated by dash-and-dot lines.
  • FIG. 1 an outer bag 1 which is doublewalled and has a filling of down, bers or any other suitable material.
  • the bag is provided with stitching 2 penetrating the two fabric layers and the filling, thus being so-called through stitchings.
  • Said stitchings are spaced suitable distances apart in the manner shown. They can be effected as straight seams or zig-zag seams.
  • the outer bag 1 carries one half 3 of a divisible zip fastener.
  • FIG. 2 is shown an inner bag 4 which is of the same construction as the outer bag 1 and thus has through stitchings 5 penetrating the two fabric layers and the filling.
  • the stitchings S are spaced substantially the same distances apart as the stitchings 2 of the outer bag, but offset in relation to the latter for the reasons mentioned in the following.
  • the inner bag is provided with a hood or cushion 6 for the head of the sleeper. Said hood or cushion is double-walled and filled with material and can be pulled together with the aid of a tie band 7 arranged in the edge of the hood and the inner bag 4.
  • the inner bag is preferably provided at the front with a zip fastener 8 and at the opening edge with the second half 9 of the divisible zip fastener the first half 3 of which is arranged on the outer bag 1 and which serves to connect together the two bags when inserted one into the other.
  • the sleeping bag is shown in its assembled state in FIG. 3, wherein the inner bag is indicated by dash lines and the two halves 3, 9 of the zip fastener have been connected together.
  • Said zip fastener 3, 9 provides so tight a closure that there is obtained between the two bags 1 and 4 an insulating and warming air volume, which is of great value at low ambient temperatures.
  • the two stitchings 2 and 5 are relatively offset to prevent, whenever through stitchings are used, the cold from penetrating into the two bags and reaching the sleeper.
  • the inner bag 4 For summer or indoor use the inner bag 4 only is ernployed in order that the temperature in the bag shall not become too high, thus making it possible for another person to use the outer bag 1. Under more exacting conditions the inner bag is inserted into the outer bag and the two bags are interconnected by means of the zip fastener 3, 9 to form a double sleeping bag with an intermediary air layer, thereby providing a very good warming effect of the sleeping bag in spite of the relatively simple construction thereof.
  • a sleeping bag comprising an outer bag, an inner bag, means detachably connecting the outer bag to the inner bag, said bags having double walls and a filling be- References Cited UNITED STATES PATENTS 1/1969 Rock Z4-204 4/1952 Howe 5--343 4 7/1945 Clark 2-69.5 5/ 1941 Hutchison 2-69.5
