Feb. 14, 1961 L. D. SHULTZ CAMPERS COMBINED PACK, HAMMOCK AND SLEEPING BAG Filed Aug. 6, 1958 2 Sheets-Sheet 1 INVENTOR. LOWELL D. S HULTZ ATTORNEYS Feb. 14, 1961 D. SHULTZ 2,971,205
CAMPERS COMBINED PACK, HAMMOCK AND SLEEPING BAG Filed Aug. 6, 1958 2 Sheets-Sheet 2 LOWELL D. SHULTZ ATTORNEY$ CAMPERS COMBINED PACK, HAMMOCK AND SLEEPING BAG The present invention relates to sleeping bags.
The primary object of this invention is to provide a sleeping bag which folds so as to provide a pack sack end which also can be used as a hammock.
Another object of the invention is to provide a sleeping bag having all three of the above features incorporated within the same, providing an unique combination.
Other objects and advantages will become apparent in the following specification when considered in the light of the attached drawings, in which:
Figure l is a plan view of the invention in an unfolded position ready for sleeping purposes.
Figure 2 is an inverted plan view of the device as illustrated in Figure 1.
Figure 3 is a side view of the invention.
Figure 4 is a plan view similar to Figure 1 after the first fold has been made when folding the bag.
Figure 5 is a side view of Figure 4.
Figure 6 is an enlarged side elevation similar to Figure 5 after the second fold has been completed.
Figure 7 is a bottom plan View of Figure 6.
Figure 8 is an inverted side elevation of the invention after the third fold has been completed.
Figure 9 is a side elevation which illustrates the final fold completed and secured.
Figure 10 is a front elevation of a completed pack.
Referring now to the drawings in detail wherein like reference numerals indicate like parts throughout the several figures, the. reference character B indicates generally a sleeping bag constructed in accordance with the invention.
The bag B is folded along the edge 10 and zipped together along the edge 11 by the usual means. The bag B is normally closed and relatively narrow at the foot end 12 and tapers outwardly toward the open head end 13 thereof.
A flap 14 forms part of the lower panel 15 of the bag B at the open head end 13 of the bag B and is for the purpose of holding the bag B in folded position. A flap 16 is fastened to the top panel 17 of the bag B at the foot end 12 thereof and is for the purpose of completing the pack in the manner to be described later.
Figures 1, 2 and 3 illustrate the bag B in unfolded position for use either as a sleeping bag or hammock. When the bag B is used as a hammock, straps 18 are fixedly secured to the lower panel 15 thereof. The ends of the straps 18 have loops 19, forming part thereof for the purpose of receiving ropes attached to two trees or the like, as indicated by the broken lines, Figure 2.
Figure 2 illustrates the device in inverted position. When in use it would be in the position shown in Figures 1 and 3. When the bag B is to be folded for storage or carrying, it is folded in such manner as to provide a pack for containing camping articles, which will be apparent from the following description.
Referring to Figures 4 and 5, the first fold is shown States Patent'O having been completed, the flap 14 is folded over as shown. In Figure 6 a second fold, including the bag B itself, has been completed. This is accomplished by holding down againstthe bagB at the point indicated by the arrow 20, referring to Figure 5, and pulling upwardly at the point indicated by the arrow 21. The portion 22 of the bag B is raised by the operator causing the fold 23, as seen in Figure 6. As the fold 23 is raised in the arc of the arrow 24, Figure 5, while the bag B is held down at the point 21), indicated by the arrow, the fold 23 will be brought down to the point 25, which completes the fold as indicated in Figure 6.
After the folds indicated in Figure 6 are made, the bag B is inverted to the position indicated in Figure 7 and the ends 26, 27 of the fiap 14 are folded over one another, and at the same time the edges 10 and 11 of the bag B are folded over reducing the width of the bag B. The edges 10 and 11 are drawn together to the desired contraction, by the straps 28 passing through the buckles 29. The final size of the pack is governed by the amount of material inserted within the space 311 the compartment for holding camping materials. The initially folded portion of the bag B is then folded over onto the unfolded portion, as seen in Figure 8.
The last fold to be made is as illustrated in Figure 8 wherein the flap 16 is folded up in the line of the arrow 31 over the folded flap 14, the straps 32 are then buckled into the buckles 33 holding the bag B folded tightly together, as best illustrated in Figures 9 and 10.
Shoulder straps 34 are provided having one end fixedly secured to the upper panel 17 of the bag B at the point 35 and the opposite end carrying snaps 36 which detachably hook into the rings 37 fixedly secured to the toppanel 17 of the bag B. 'The object of the snaps 36 are for the purpose of releasing one of the straps 34 while adjusting the bag B to the shoulders of the wearer.
Having thus described the preferred embodiment of the invention, it should be understood that numerous structural modifications and adaptations may be resorted to without departing from the scope of the appended claims.
