Description
10~3~139 BACKGROUND OF THE INVENTION
This invention relates gener~lly to a compacter ~or maintaining a bulky compressible item in a tightly rolled condition to make the item more easily transportable. The compacter is particularly useful by campers and backpackers to tightly roll items of bedding, such as sleeping bags, mattresses, foam rubber pads, blankets and the like.
A wide variety of strap-type devices exist in the prior art for clamping or holding a wide variety of different articles. For example, s~rap-type devices have been used to hold different types of articles on a supporting platform (see U. S. Patent Nos. 2,852,827 and 2,896,296); to apply a com-pressi~e force to opposed platens of a hand press (see U. S.
Patent No. 2,448,288) and to anchor large articles, such as . mobile homes, planes or boats (see U. S. Patent Nos. 3,673,6~2 and 3, 881,694). Although all of these devices include a mechanism for tightening a strap, or band, to either clamp or ~ .
hold one or more articles, none of these mechanisms are parti-cularly well suited for use in low cost, light weight, easy to operate units of the type that a camper might use to tightly roll up a sleeping bag or similar item, to make it more easily transportable.

10~3Z139 1 DESCRIPTION OF THE PREFERRED EMBODI~ENTS OF T~IE INVENTION
Although specific terms are used in the following descrip-tion for the sake of clarity, these terms are intended to refer only to the particular structure of the invention selected for illustration in the drawings, and are not intended to define or limit the scope of the invention.
This invention relates to a compacter 10 for maintaining a bulky, compressible item in a tightly rolled condition to make the item more easily transportable. Although the compacter can be used to roll up many different items, it is primarily intended for use in wrapping up camping items, such as sleeping bags, to make them less bulky, and therefore easier to store or carry. For purposes of illustration, this invention will be described in connection with the compacting, or rolling up of a sleeping bag, designated by the numeral 12 in the drawings.
Referring to Fig. 1, the compacter 10 of this invention includes a strap 14 made of a flexible and highly durable material. For example,the strap can be made of nylon or canvas, and preferably is treated to be water repellant so that the sleeping bag 12 will be maintained in a relatively dry condition in the event it is being carried in the rain. The strap 14 includes opposed, laterally extending end margins 16 and 18 that are overlapped with each other, and the overlapped regions are connected together by spaced apart, laterally extending seams to form a laterally extending loop 20.
Referring specifically to Fig. 1, the compacter 10 includes a rigid winder 22, including an elongate, rod-like section 2~ extending completely through the loop 20 t and a transversely offset lever section 26 to provide a mechanical ~08~:~39 1 advantage to rotate the rod-like section 24. Preferably, the winder 22 is made from aluminum, or other material that will not rust or otherwise corrode when exposed to adverse weather conditions.
The rod-like section 24 includes a plurality of spaced-apart openings 28 extending through it, and stitching, schematically indicated at 30, is passed through these openings and portions of the strap 14 that form the loop 20 to provide a mechanical connection between the strap and the winder 22. As a result of this connection, the rotation of the winder 22 in a clockwise direction, as indicated by arrow 31 in Fig. 2, will cause the strap 14 to roll up from its end margins 16 and 18 onto the rod-like section 24 to tightly compact the sleeping bag 12, as shown in Figs. 3 and 4. The winder 22 is rotated through the lever section 26 to establish a mechanical advantage for r~tating the rod-like section 24. This permits an extremely tight compaction of the 'sleeping bag 12 to make it easy to store or carry.
Referring to Figs. 1 and 2, the compacter 10 includes a winder guard 32 that is positioned inside the closed area 33 of strap 14, between the rod-like section 24 of the winder 22, and the sleeping bag 12. This guard 32 prevents the sleeping bag 12 from winding up onto the rod-like section 24 of the winder.
Referring to Fig. 1, the winder guard 32 includes a laterally extending central base section 34, and laterally extending flanges 36 and 38 extending upwardly and diverging out-wardly from said base section. As can be seen best in Figs. 2-4, the base section 34 of the winder guard underlies the rod-like section 24 of the winder, and the laterally extending flanges 36 and 38 , : _ . .
3Z3 ~
1 cooperate with the base 34 to isolate the rod-like section of the winder from the sleeping bag.
Referring to Figs. 1 and 4, rotatable support ~or the winder 22 is provided by laterally spaced apart, bearing surfaces 40 and 42. The bearing surfaces 40 and 42 may be U-sh~ped ~s illustrated or may be circular openings through which the rod-like section 24 can insert for rotation therewithin~ These suF-faces are provided in end flanges 44 and 46, respectiyely~ pro-jecting upwardly from the central base section 34 of the winder guard 32. In order to prevent the winder 22 from shifting axially out of the bearing surfaces 40 ~nd 42, a nut 48 is threaded onto the end of the rod-like section 24 opposite the level section 26 to bear against the outer surface of the end flange 46 (Fig. llr Optionally, the winder 22 can terminate in ~ plain ena and a push nut would be employed to maintain the parts together~
Referring to Figs. 3 and 4, a latchin~ syste~ 50 is .. . .
provided to prevent the winder 22 from rotatin~ in a counter-clockwise direction, as viewed in Fig. 4, to unwind the strap 14.
In other words, the latching system 50 maintains the compacte~
in its compacting condition. This system includes a flexible strand 52, such as string, rope, cable and similar materials, and hooks 54 and 56 connected to opposed ends of the strana. The strand 52 extends laterally across the strap 14, and the hooks 54 and 56 are engaged, respectively, within opening 58 pxovided through the lever section 26 of the winder 22~ and ~n opening 60 provide in the uptuxned end flange 46 of the winder guard 32.
It should be apparent that the connection of the strand 52 to the lever section 26 of the winder, as illustrated, will pxevent counterclockwise rotation of the winder tha~ would unroll the strap 14. When it is desired to use the sleeping ba~ 12, the latching system 50 can be disenga~ed easily to permit the strap 14 to be unwound. Also, it is an extremely simple operation to win~ up and latch the compacter 10 when it is desired to store or transport the sleeping bag.
