ATTOP N EYL United States Patent 'SLEEPING BAG STRUCTURE Frederick J. P. van Veen, Ottawa, Ontario, Canada Application December 31, 1952, Serial No. 328,843
2 Claims. (01. 2-69-5) V This invention relates to new and useful improvements in sleeping bag structure.
It is one of the objects of the present invention to provide a device of this character in which the sleeping bag as a unit is efiectively and efliciently insulated throughout.
Another object of the present invention is to provide a device of this'character wherein the joined edges of the sleeping bag are so constructed that they afford a thickness of material that is comparable to at least the thickness of the body portion of the sleeping bag.
A further object of the invention is to provide structure of this character in which the entrance closure of the sleeping bag is provided'with overlapping flaps to insure full insulating thickness of material at the closure point when the sleeping bag is closed.
Still a furtherobject of the invention is to provide structure of this character wherein the upper and lower sections of the sleeping bag-have partition walls formed thereinwhich provide closed channels or compartments in' which insulating material is retained.
Yetanother object ofthe present invention is to provide a device of this character in which the channels or compartments are so arranged that they form substantially V or zig-zag compartments for purposes of maintaining an even distribution of the insulating material therein.
Having regard to the foregoing and other objects and advantages which will become apparent as the description proceeds and the details become known, the invention consists essentially in the novel combination and arrangement of parts hereinafter described in detail and illustrated in the accompanying drawings in which:
Fig. l is a plan view disclosing an embodiment of my present invention, the closure flaps being illustrated in a partly open position.
Fig. 2 is an enlarged sectional view taken on the line 2-2 of Fig. 1.
Fig. 3 is a view in elevation as seen from the lines 33 of Fig. 1 with the flaps in closed position.
Fig. 4 is an elevational view of a portion of the sleeping bag showing the hood attached to the seam closing compartment of the sleeping bag adjacent the closure opemng.
Fig. 5 illustrates a modified form of seam closing compartment for the sleeping bag.
Fig. 6 illustrates a further modified form of seam closing compartment for the sleeping bag, and
Fig. 7 shows a fragmentary portion of a modified form of sleeping bag with the compartments of the main body arranged in zig-zag form. 7
Referring now to the accompanying drawings wherein the present invention is disclosed and wherein like numerals of reference designate corresponding parts in the various illustrations, the numeral 15 indicates the sleeping bag as a whole While numeral 16 indicates a hood or head cover attached thereto.
The sleeping bag as a unit is elongated in form, provided with upper and lower wall sections and closable "ice entrance means. The prime purpose of the sleeping bag is to provide outside sleeping accommodation for travel: lers, prospectors, explorers, hunters, etc., who, for periods of time, live outdoors and who, during such outdoor living, are subject to varying and not infrequently severe weather conditions. It is most important therefore that the sleeping bag be thoroughly insulated especially at the seam closing points to guard against the infiltration of cold and undesirable air and weather.
As illustrated, the sleeping bag comprises upper and lower body sections 17 and 18 between which the occupant rests or sleeps. spaced upper and lower main walls 19-20 and 2122 respectively while each of the upper and lower sections is provided intermediate its walls with a series of spaced compartment forming partition walls 23. The partition walls may be stitched or otherwise secured between the respective'upper and lower walls of each section as indicated at 24 and thus provide a series of closed channels or compartments 26 for the reception of down or other suitable insulating material 27.
As previously mentioned and as illustrated in Fig. 1, the
compartments 26 may be of substantially V shape formation as indicated at 28 or as illustratedin Fig. 7, they may be of zig-zag formation as indicated at 29. With the compartments arranged as indicated, it will be seen that any movement of the insulating material in the respective cornpartments is reduced to a minimumand as a result a relatively even distribution and thickness of insulating material is maintained throughout the upper and lower sections of the sleeping bag. For purposes of providing full insulating properties at the joinededges or seams'of the sleeping bag, I provide a supplementary or seanrclosing compartment, such compartment embracing and insulatingly enclosing the joined seams of the sleeping bag, especially the edge'joini'ngseams thereof.
In constructing the sleeping bag, the outer edges of the walls 20 and 21 are stitched or otherwise secured together by inner seams 30 while the edges of the walls 19 and 22 are also secured together by means of stitching or other appropriate securing means indicated at 31. By such novel arrangement and structure it will be seen that a seam closing compartment 32 is provided, such compartment extending over and insulatingly enclosing the inner seaming which is then provided with a thickness of insulation comparable to at least the thickness of the upper and lower sections of the sleeping bag body. From the foregoing it will be seen that both novel and practical means are provided for guarding against infiltration of cold or undesirable air currents at the joining seams of the sleeping bag.
As previously mentioned, the entrance or closure means of the sleeping bag is also provided with eflicient and practical means for guarding against the infiltration of cold or objectionable air or drafts at the point of closure. The means for accomplishing this comprises arranging inner and outer closure flaps in staggered and overlapping relationship to one another. The inner flap which is designated by the numeral 34 is fixedly secured to the underside of the top section 17 as at 35' and as particularly illustrated in Fig. 3, its fastening edge 36 is arranged in spaced relationship to the detachably fastening edge 37 of the outer flap 35. Thus when in closed position, the flaps 34 and 35 overlap one another and their respective detachable fastening edges are connecting points spaced one from the other. As a result of this arrangement, a full thickness of insulation is provided at the entrance or closure point of the sleeping bag.
Suitable closure or fastening means are provided for the respective flaps 34 and 35 and in the present instance I have illustrated the well known zipper fastener which is Each of these sections are composed of V eiitran'ce'of the sleeping bag.
however that other types .ofjclosure fastening means may beemployed such for example as dome or glove fasteners o'rfthe lik'e without departing from the spirit of the invention; 7 V
Byreference toFig. 4, it will be seen that the hood 16 is detachably or otherwise secured to the underside of the seam closing compartment 32 as indicated at .40. By virtue'ofthis means of connecting the hood it will again be seen that provision is made to'prote'ct the user from the elements. v V In the modification of structure shown irrFig. 5, the
seam closing compartment formedby securing a partitionwall '42t'othe -walls..20 an d 21 while theedges of members 19 and 20, and 21 .and 2'2, are allstitched toment 44,
-gether as indicated at 43 to form searn closing compartlimitative sense and that'all changes coming "within the 7' meaning and range of equivalency of the claims are in- V tended to be' embraced therein.
What I claim is:
1. A sleeping bag comprising upper and lower sections,
each said section having an upper and lower wall and in- 'sulating material therebe'twem-the lower wall of said its the modification or the invention" seen in Fig.6, the
edges of the walls 19 and 20, and 21 and 22 are stitched together 'as indicated at while 'a closure piece of material is stitched or otherwise secured to the upper and lower walls a's indicated at 46 to provide the seam closing compartment 47. r 7 -While in the present instanceI have conveniently shown the seams and the seam closing compartment arranged at v the outer edges ofthe sleeping bag, it will be understood that the seamclosing compartments could be arranged at r a differentpoint of the sleeping bag. 7
From the foregoing it will be seen that the present structure provides novel yet positive insulation throughout all points'of the sleeping bag and includes insulating the joined seams as'well as a fullithickness ofinsulation at the closure I Many changes may bemade in the abovefand many apparently widely different embodiments constructed without departing from the'spirit or the essential characteris tics of the invention. It is intended therefore that the dis- 1 closure herein'be interpreted as illustrative and notin a 613,545 1,808,233 "Karnr'ath V J ne .2, 93
