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.

- The present invention generally relates to a folding device of significant dimensions and strength for the rolling up of sleeping bags, self-inflating sleeping pads, airbeds, flexible exercise mats, flexible sleeping mats, bed covers, and other similar bedrolls. More particularly to a folding device having a rigid frame-like construction of size to allow the widthwise insertion of a sleeping bag, or self-inflating sleeping pad, or airbed, or flexible exercise mat, or flexible sleeping mat, or bed cover, or other similar beddings, and or the like into the enclosed aperture space; and of sufficient strength when turned along the longitudinal axis would facilitate the compressing of the sleeping bag, or pad, or airbed, or mat, or bed cover, or other similar beddings, and or the like into a tight roll.
- Typically sleeping bags, pads, airbeds, mats, bed covers, and other similar beddings are purchased in a tightly compact roll. Once opened from the original package, it is very difficult to fold them back to their former shapes. This difficulty stems from the inability of most hands to grasp evenly and firmly across the width of the soft sleeping bag, or pad, or airbed, or mat, or bed cover, or other similar beddings, and or the like. This inability often causes the rolling up process to produce a loose bundle which is unwieldy to carry and tends to come apart. To achieve a tight roll requires considerable strength, time and effort; and, is particularly difficult for children because they often lack the strength, grasp and patience required.
- Specific attempts to solve the above-identified problem for sleeping bags and the like were proposed in numerous inventions. U.S. Pat. No. 3,533,572 entitle, “Mandrel for Rolling Bedding” granted to Rowell W. Sims on Oct. 13, 1970 discloses a pair of elongated slender rods which are placed widthwise over and under bedding and fastened together at corresponding ends securing the thickness of the bedding between the rods to form a clamping mandrel on which to roll the bedding. The described mandrel is constructed of two separate and identical hardwood rods each of which includes a pin protruding from one end and a length of flexible anchoring material such as string or chain attached at the other end. The hardwood rods are disposed in parallel spaced-apart configuration with the thickness of the bedding between the rods and are fastened together at corresponding ends by tying or wrapping the anchoring material about the protruding pins to secure the thickness of the bedding between the rods and provide rigidity across the width of the bedding. Due to the flexible anchoring materials at the ends of the rods, this device requires both a firm grasping and a turning motion to be applied simultaneously when compressing the bedroll. In addition, the hands have to periodically release the grip and reposition to advance the rolling-up process. These multiple-step motions make this mandrel difficult to use in general. And particularly it is very difficult to use for children and people with limited hand and grip strengths.
- U.S. Pat. No. 4,973,009 entitle, “Key for Rolling Sleeping Bags” granted to M. Lynn Dunlap on Nov. 27, 1990 discloses a pair of tubular plastic rods which are pivotally attached at one end. One of the rods is pivotally displaced to a position parallel to and spaced from the other rod. Together the rods form an open ended fork or key. A metal hook inserted through holes in the free ends of the rods fastens the free ends together and clamps a sleeping bag securely between the rods. A handle is attached to the end of the non-pivotable rod. In use, the key device is first clamped in place. The handle is then turned to advance the rolling up of the sleeping bag. In practice, since the handle is attached at only one end of the device, the sleeping bag would tend to roll up crooked. Furthermore, with only one handle, this key device does not fully utilize the strength of both hands. Thus, this invention is likewise difficult to use in general. And particularly it is very difficult to use for children and people with limited strength.
- In Canter et al., U.S. Pat. No. 5,184,361, a storage apparatus is described for “furling” or “curling” sleeping bags. This storage apparatus consists of a rigid tubular member, an elastomeric strap and accessories used for storage. To curl the sleeping bag, the bag is first inserted between the rigid tubular member and the elastomeric strap. The elastomeric strap is intended for positioning the sleeping bag on top of the tubular member, prior to curling. Because it is elastic, the strap is not meant to provide a means of simultaneous folding and compressing the sleeping bag. Once in place, the sleeping bag is curled by rolling the bag over the “storage apparatus”. Since no direct pressure is applied by Canter's storage apparatus onto the sleeping bag, the end result would be a loosely furled roll.
- None of the above or other exiting inventions teach the embodiments of the present invention or provide the benefits disclosed below.
- A 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 beddings, and or the like constructed according to the principles of the present invention comprises a rigid frame-like structured unit. This frame-like folding device can be rectangular or oblong in shape. The embodied invention may be formed from a single piece of rod, pipe or strip-like material or other suitable materials. It may also be constructed from an assortment of properly formed joinable and detachable rods, pipes or strip members of any suitable, light-weight, stiff and strong materials.
- The frame-like folding device is shaped to provide an adequate enclosed opening of sufficient dimensions for the widthwise and thickness-wise insertion of the sleeping bag, or self-inflating pad, or airbed, or flexible foam mat, or bed cover, or similar bedding, or the like to be rolled. It is also fabricated from materials with sufficient rigidity to allow adequate force to be applied to advance the rolling up process.
- When the frame-structured device is manufactured from a single piece of rod, pipe or strip-like material or other suitable materials, it can be heat pressed or stamped into the desired frame shape. When the folding device is formed from an assortment of fabricated attachable and detachable rod, pipe or strip-like members, numerous embodiments are possible. One such embodiment consists of two equal or unequal “U” shaped members mated together to constitute the rigid frame-like construction. Another embodiment with multiple members consists of two significantly elongated straight rods, tubes or strips or other suitable materials as the longer sides with two shorter joinable side members joined together to constitute the rigid frame-like construction.
- When using this folding device, the widthwise end of the sleeping bag, or pad, or airbed, or mat, or bed cover, or bedding or the like is first inserted into the middle open space between and parallel to the two longer sides of the rigid frame-like construction. The shorter sides of the frame construction are then gripped, pressed down and turned to tightly compress the sleeping bag, pad, airbed, mat, bed cover, bedding or the like into a compact roll. With the first turn of the folding device, the enclosed bed roll becomes automatically clamped in place.
