Folding Device for Rolling Up Sleeping Bags, Self-Inflating Pads, Airbeds, Foam Mats, Bed Covers, and Other Bedrolls

Abstract

A rigid frame-shape folding device for rolling up sleeping bags, self-inflating sleeping pads, airbeds, flexible foam mats, bed covers, other similar beddings, is described that consists of a rectangular or oblong construction, with adequate opening for the thickness-wise insertion of the short end of the bedrolls. The rigid frame device is made from tubular materials and is sufficiently strong to withstand the force applied during the folding process. The folding device consists of two curved tubular members with “male” and “female” interlocking means. Also shown is an adjustable rigid frame folding device for bedrolls of different sizes that comprises of four interlocking tubular members. When using this folding device, the bedroll is first inserted into the middle open space, between and parallel to the two longer sides of the frame device. The shorter sides of the frame are gripped and turned to compress the roll. After compressing and securing the roll, the device may remain embedded since it is light in weight and occupies little space. The exposed end may also serve as a handle for transporting the bundle. The device may also be easily extracted from the folded bedroll by first disengaging the tubular members.

1 . A rigid frame-shape folding device for rolling up sleeping bags, or self-inflating sleeping pads, or airbeds, or flexible exercise mats, or flexible sleeping mats, or bed covers, or other similar bedrolls comprising:
 two rigid, elongate and curved, tubular members of significant strength, and of adequate dimensions, when connected together form an enclosed sizeable aperture space that allows the thickness-wise and widthwise insertion of said bedrolls; and,   said tubular members have “bell” shape and straight ends as means of mating the said members.   
   
   
       2 . A rigid frame-shape folding device as in  claim 1  wherein said two tubular members are secured together by a quick release locking means. 
   
   
       3 . A rigid frame-shape folding device as in  claim 2  wherein said quick release locking means is a spring loaded pin and hole mechanism. 
   
   
       4 . A rigid telescoping adjustable frame-shape folding device for rolling up sleeping bags, or self-inflating sleeping pads, or airbeds, or flexible exercise mats, or flexible sleeping mats, or bed covers, or other similar bedrolls comprising:
 two rigid, curved tubular members of longer and shorter lengths and both with identical curvatures comparable to the thickness-wise dimension of said bedroll; and,   two identical, rigid, elongate tubular members of inside diameter sufficiently large enough for the insertions of said longer curved member; and,   two quick release locking means for securing said longer curved member to said two identical elongate tubular members, thus forming an expandable curved member adjustable to the lengths of any bedrolls; and,   a quick release locking means for securing said shorter curved member to said expandable curved member.   
   
   
       5 . A rigid telescoping adjustable frame-shape folding device as in  claim 4  wherein said two quick release locking means for the lengthening of said longer curved member are two spring loaded pin and hole mechanisms. 
   
   
       6 . A rigid telescoping adjustable frame-shape folding device as in  claim 4  wherein said two quick release locking means for the lengthening of said longer curved member are two twist lock mechanisms. 
   
   
       7 . A rigid telescoping adjustable frame-shape folding device as in  claim 5  wherein said quick release locking means for said shorter curved member is a spring loaded pin and hole mechanism. 
   
   
       8 . A rigid telescoping adjustable frame-shape folding device as in  claim 6  wherein said quick release locking means for said shorter curved member is a spring loaded pin and hole mechanism.
