Definitions

  • This invention relates to sleeping bags and more particularly to sleeping bags having a variable insulative capacity.
  • a sleeping bag it is desirable to be adaptable for use in a broad range of temperature environments without the need to resort to an entirely different sleeping bag with which to do so.
  • the sleeping bag ideally suitable to one seasonal, climatic, or geographic circumstance is frequently over-insulated, and thus too warm, or under-insulated,and thus too cool, for a different set of conditions.
  • those who use sleeping bags in significantly varying circumstances can be confronted with fatigue resulting from uncomfortable sleep, and in extreme circumstances with illness or loss of life or limb, if the same sleeping bag is employed unmodified in different environments.
  • a given user can employ sleeping bags of differing weights, as with a summer and a winter weight sleeping bag, or a low and a high altitude sleeping bag, using each in the alternative as circumstances may demand.
  • two or more light or medium weight sleeping bags may simply be utilized one within the other as decreasing external temperatures force the user to add insulation in order to maintain warmth.
  • Sleeping bags are known in which the problem of varying external temperature conditions is met by constructing a sleeping bag comprising a number of parallel horizontal insulative layers all secured along one logitudinal edge like the pages of a book.
  • the user of such a sleeping bag sleeps between those of the layers as produces comfortable results, given the temperature outside. In warmer weather the user rests among the layers so that most of them are below, while in colder weather most should be above.
  • Many of these types of sleeping bags are little more than one sleeping bag within another, the user being able to sleep not just within the inner bag, but also upon both of the layers of the inner bag in warm weather and under both of them in cold weather.
  • One object of the present invention' is a sleeping bag which can be adapted to a wide range of temperature conditions.
  • Another object of the present invention is a sleeping bag of variable insulative capacity which maximizes the effective use of insulative material in doing so.
  • Yet another object of the present invention is a sleeping bag for use in a wide range of temperatures which efficiently employs insulative material and yet minimizes the portage weight of the sleeping bag, particularly in milder temperature conditions.
  • a final object of the present invention is a sleeping bag which, though originally acquired for mild weather use, can easily be adapted to more severe temperatures.
  • a system for selectively increasing the thermal operating range of a sleeping bag comprises a plurality of discrete mantles of varying insulative capacity; and means for removably securing a selected one of the mantles superimposed on the upper surface of the sleeping bag.
  • a sleeping bag having top and bottom insulating layers between which a user is to rest, is_provided with the improvement comprising a separate insulative mantle substantially congruent to the top insulating layer; and means for removably securing the mantle superimposed on the outer surface of the top insulating layer for selectively enhancing the thermal operating range of the sleeping bag.
  • the means for removably securing the mantle comprises first attachment means on outside edges of the sleeping bag; and second attachment means on the mantle cooperating with the first attachment means.
  • first attachment means comprises at least one first zipper track and the second attachment means comprises at least one second zipper track.
  • a conventional sleeping bag is shown to comprise a bottom insulating layer 10 and a top insulating layer 12 joined together at a shared longitudinal edge 14.
  • bottom insulating layer 10 and top insulating layer 12 are folded along longitudinal edge 14 so that a user is sandwiched between insulating layers 10, 12, while free longitudinal edge 16 of bottom insulating layer 10 and free longitudinal edge 18 of top insulating layer 12 meet opposite the occupant from shared longitudinal edge 14, as already known.
  • bottom insulating layer 10 frequently extends beyond the top edge 20 of top insulating layer 12 to form a head rest or hood 21.
  • Means are usually provided for securing together free longitudinal edges 16, 18.
  • a zipper track 22 attached to free longitudinal edge 16 of bottom insulating layer 10 is a zipper track 22, while attached to free longitudinal edge 18 of top insulating layer 12 is a zipper track 24.
  • zipper tracks 22, 24 cooperate to close the gap between longitudinal edges 16, 18.
  • insulating layers 10, 12 are either permanently secured together or separably engaged through the provision on insulating layers 10, 12 of extensions of cooperating zipper tracks 22, 24.
  • a sleeping bag as has been described thus far will have a generally fixed minimum operational temperature below which the body heat of an occupant cannot be effectively conserved.
  • a system is provided for selectively increasing the thermal operating range of such a sleeping bag. As seen in Figs. 1 - 3, an additional insulating layer or mantle 30 which is substantially congruent to top insulating layer 12 is placed resting upon top insulating layer 12 to add insulation above the user.
  • Mantle 30 is representative of any one of a plurality of discrete mantles of varying insulative capacity and wind or moisture resistant construction, the appropriate mantle from the plurality of discrete mantles being selected for use according to the degree of added insulation and temperature protection desired under a given set of circumstances.
  • the top surface 32 of mantle 30 may advantageously be composed of a number of different materials, some water resistant, such as a laminate of expanded polytetrafluoroethylene. To the extent that top surface 32 of mantle 30 serves to decrease convection, thermal insulation is increased by retarding the upward flow of heat away from the body of the occupant.
  • means are provided for removably securing mantle 30 superimposed on the upper surface of top insulating layer 12.
  • first attachment means which cooperate with second attachment means located respectively at longitudinal edges 14, 18 of top insulating layer 12.
  • second attachment means located respectively at longitudinal edges 14, 18 of top insulating layer 12.
  • zipper tracks 38, 40 attached respectively to longitudinal edges 34, 36 of mantle 30.
  • Upon longitudinal edges 14, 18 of top insulating layer 12 are secured respectively zipper tracks 42, 44.
  • zipper tracks 46, 48 engages track 42 and zipper track 40 engages track 44 to securely attach mantle 30 to the top surface of top insulating layer 12.
  • mantle 30 is prevented from sliding off the top of the sleeping bag to which it is attached due to motions of the user or the action of wind.
  • mantle 30 may be secured along its entire exterior perimeter; however, it has been found sufficient to so attach mantle 30 only along longitudinal edges 34, 36.
  • a single sleeping bag can be rendered capable of serving its user comfortably in a wide range of temperature conditions.
  • the additional insulative material contained in a mantle used by the method of the present invention to enhance the insulative capacity of a sleeping bag is placed entirely above the user to maximize its effectiveness, and yet is completely separable from the sleeping bag so as to minimize portage weight associated with sleeping gear when milder temperatures are expected.
