The present invention relates generally to a personal exercise and myofascial release device in the form of a foam covered roller.
Foam rollers have been growing in popularity in recent years. Using a foam roller is the best way to perform self-massage and myofascial release. Used before exercise foam rolling can increase blood flow and prepare the muscles for exercise. A foam roller can also help loosen tight muscles, reduce muscle adhesions and scar tissue formation and increase body flexibility.
The simplest form of such a roller is a round tube of foam that looks like a rolling pin. More advanced designs include, on the surface of the foam, flexible bumps for muscle penetration and treatment of trigger points along with variations of the density of the foam. From solid core rollers, the prior art includes hollow core tubes whose outside surface is covered with smooth or textured grid patterns. The interior of the hollow tube version has seen use as storage space with end caps on the tube to retain the stored contents.
The primary object of the present invention is to provide a foam roller construction that will provide easy access to the interior of the roller for storage of such items as exercise floor mats but will, at the same time allow the roller to be unfolded into two adjacent tube halves whose outside foam covered grid surfaces provide stationary support for a different kind of muscle therapy than that administered by a roller.
A second object of the invention is to provide a foam roller whose entire interior can be viewed and easily accessed for storage purposes by utilizing hinged tube halves to create the roller where the tube halves pivot around hinges to open the roller in the manner of a suitcase for ease of storage and retrieval.
Other further objects, features and advantages of the present invention will become apparent from the following description of the invention taken in conjunction with the accompanying drawings.
The roller of the present invention comprises two identical cylindrical tube halves that are interconnected with hinges along a first one of their longitudinal edges. A fastening mechanism is provided to selectively lock the second longitudinal edges together, thus forming a cylinder. The outside surface of the cylinder is covered with a foam material such as ethylene-vinyl acetate which may be smooth or grooved or textured with grid forming dimples, flexible bumps or tread on all or a portion of the outside surface of the roller. The interior of the formed cylinder may be used for storage of such items as an exercise floor mat and additional storage spaces in the form of compartments are also provided. An alternative embodiment of the roller may be shorter in length than a rolled exercise matt with the matt being retained between the closed roller halves. With these novel features the foam covered cylinder may be used as an exercise roller for performing self-massage and myofascial and trigger point release. Exercises can be performed with the cylinder opened with the longitudinal edges of the tube halves in contact with the floor. In that configuration the foam covered tube halves become stationary and useful as fixed pressure points for areas of the body such as the gluteus maximus or for core exercises such as sit-ups, using the stationary tube halves as a fulcrum. Following the roller exercise regimen, the roller is opened and the exercise mat may be conveniently secured within the roller.
The preferred form of the foam exercise roller 2 of the present invention is illustrated in
The open position of the roller reveals the hollow interior of the tube halves 4 and 6 being utilized for storage space, generally indicated by reference numeral 20 in
Semi-circular end caps 28 are disposed at the terminal ends of each tube half to complete the enclosure of the interior of the roller when the tube halves are closed. The end caps may be perforated with one or more apertures to allow for the passage of air through the interior of the roller.
The outer surface of each tube half is covered with one or more arrangements of foam. For most foam configurations ethylene-vinyl acetate is preferred. In the preferred embodiment there are multiple sections of foam covering, each of which may be covered with different kinds or densities of foam or different foam surface configurations to effect different kinds of muscle pressure. The center section 30 of the roller 2, that is, the combination of short sections on both sides of the circumferential groove 32 of the tube halves, is covered with a smooth surface variety of foam having broad grooves 34 angularly disposed to the longitudinal edges of the tube halves and traversing across the outer surface of the center section of foam, as shown in
The end portions 40 and 42 of each tube half are preferably covered with a higher density and roughly textured foam, including dimples, flexible bumps and narrow grooves adapted to apply the necessary local pressure to achieve the desired myofascial and trigger point release.
As illustrated in
Pivotally hinged to the respective inside longitudinal edges are arcuate grasping arms 72 and 74 which are provided to hold an exercise mat 80 in storage within the roller 50 when the roller is not in use or in transit. Each of the arms carries extensible pressure nubs 76 that engage the body of the rolled exercise mat 80 to retain the mat within the arms when the tube halves are closed, as shown in
Each of the tube halves of the alternative embodiment are preferably covered with ethylene-vinyl acetate foam 82 that carries broad angular grooves 84 or some other desired texture or a grid pattern which produces the local pressures that the roller applies to muscles of the body.
