FIELD
The disclosure relates to a massage roller, more specifically, a massage roller that can be affixed to a stationary support structure, e.g., a power rack or door frame.
BACKGROUND
Exercise, to any significant degree, causes micro-tears in muscle tissue. Additionally, as an individual exercises, muscle tissue burns stored glucose for energy. Lactic acid is a metabolic byproduct of muscle tissue breaking down stored glucose, and often leads to muscle fatigue. Over time, blood flow to the afflicted area both removes lactic acid from the muscle tissue and allows white blood cells, known as prostaglandins, to flood the area to reduce inflammation caused by the micro-tears. Therefore, muscle recovery and removal of lactic acid are directly correlated with blood flow the afflicted muscle tissue. One well know technique for promoting blood flow to muscle tissue, and thus accelerating recovery of the muscle's performance, includes direct application of external physical stress, e.g., massaging the afflicted muscle.
Two-handed massage rollers are well known to athletes and connoisseurs of exercise as a way to massage muscles such as the quadriceps, hamstrings, calves, and glutes. However, one persistent limitation to two-handed massage rollers is the limited range of muscles that can be massaged, i.e., it is difficult to massage a user's triceps when both of the user's arms are holding the massage roller. For example, it is exceedingly difficult, if not impossible, to use a two-handed massage roller to massage a majority of the muscles in a user's back.
Thus, there is a long-felt need for a massage roller that does not require the use of two hands to massage muscle tissue. This creates the possibility of massaging muscles not previously accessible to two-handed massage rollers.

In fact, it may be desirable to position joints 336 and 344 at different heights, corresponding to different through-bores of first plurality of through-bores 356 and second plurality of through-bores 358 so that different muscle areas, e.g., a user's latissimus dorsi, can be massaged easily.
FIG. 12 is a side view of door anchor 402 which can be used in association with roller device 400. Door anchor 402 includes a clip 404, a first strap 406, and a second strap 408. Clip 404 is depicted as a substantially D-shaped carabiner clip having a spring-biased gate arranged to quickly connect to a piece of equipment. First strap 406 has first end 410 and second end 412. First end 410 is arranged to secure to clip 404, and second end 412 is arranged to secure to second strap 408. Second strap 408 is secured to first strap 406 such that second strap 408 is substantially orthogonal to first strap 406. Second strap is operatively arranged to contact the back of door 416 described infra.
FIG. 13 is a perspective view a door anchor 402 as used in association with roller device 400 in anchor-assembly 414. It should be appreciated that the handle and connectors depicted in association with roller devices 100, 200, and 300, can be mixed and matched as embodied by roller device 400. Roller device 400 comprises substantially the same elements as described in association with devices 100, 200, and 300, except that device 400 has 422 handle at one end, and connector 424 at the other. Handle 422 is substantially similar to handle 108 described supra. Connector 424 is substantially similar to connector 210 described supra. Door anchor 402, is initially positioned against the doorjamb of door 418, between door 418 and wall 416 and above door handle 420. Door 418 can then move to the closed position as depicted in FIG. 13 clamping door anchor 402 in place. After door anchor 402 is locked in place, connector 424 of roller device 400 can be clipped to clip 404 of door anchor 402. In this arrangement a user only needs to use one arm instead of two arms to grip handle 422 and impart a pressure force to roller device 400. By only using one arm it becomes possible to use door anchor 402 in conjunction with roller device 400 to massage muscle groups while only using one arm. It should be appreciated that by mixing handles and connectors as described above, it is possible to have roller devices 200 and 300 with a handle at one end and a connector at the other in which the devices could be used in a similar one-armed fashion as described above.
FIG. 14 is a perspective view of roller device 500. Roller device 500 includes first tube 502, first rod 504, second rod 506, first handle 508, second handle 510, first pressure clamp 512, second pressure clamp 514, first roller 516, second roller 518, and third roller 520. First tube 502 includes first end 522, second end 524, and through-bore 526 (shown in FIG. 15). Through-bore 526 of first tube 502 is concentric with, and passes completely through, first tube 502. First rod 504 has first end 528 and second end 530. First end 528 of first rod 504 is fixedly secured to handle 508. Second end 530 of first rod 504 is arranged to slide within, and telescopingly engage with, through-bore 526 of first tube 502. Second rod 506 has first end 532 and second end 534. First end 532 of second rod 506 is arranged to slide within, and telescopingly with, through-bore 526 of first tube 502. Second end 534 of second rod 506 is fixedly secured to second handle 510. First handle 508 and second handle 510 are depicted as substantially cylindrical members with one rounded end and can be made of various materials, e.g., rubber, foam, or plastic such as high-density polyethylene. First handle 508 and second handle 510 are intended to be gripped by a user's hand, or engage and be supported by brackets (not shown), such that a pressure force may be exerted by device 500 to a user's muscle.
First pressure clamp 512 is fixedly secured to first end 522 of first tube 502 and arranged between first rod 504 and first tube 502. When first pressure clamp 512 is disengaged, first rod 504 can slide within, and telescopingly engage with, through-bore 526 of first tube 502. When engaged, first pressure clamp 512 is operatively arranged to provide a pressure force about the circumference of first rod 504 and prevent movement of first rod 504 in both axial direction AD1 and axial direction AD2. Similarly, second pressure clamp 514 is fixedly secured to second end 524 of first tube 502 and arranged between second rod 506 and first tube 502. When second pressure clamp 514 is disengaged, second rod 506 can slide within, and telescopingly engage with, through-bore 526 of first tube 502. When engaged, second pressure clamp 514 is operatively arranged to provide a pressure force about the circumference of second rod 506 and prevent movement of second rod 506 in both axial direction AD1 and axial direction AD2. Roller device 500 further includes first roller 516, second roller 518, and third roller 520. Rollers 516, 518, and 520 are arranged about first tube 502. Roller 516, 518, and 520 are operatively arranged to rotate in rotational direction RD1 and not in second rotational direction RD2. This this one-way rotation is made possible by plurality of teeth 538 (shown in FIG. 15) and stopping element 540 (shown in FIG. 15). It should be appreciated that although three rollers, i.e., rollers 516, 518, and 520 are depicted, additional rollers may be provided. Furthermore, it is contemplated herein that at least one roller, i.e., one or more rollers could be disposed about first tube 502.
FIG. 15 is depicts a cross-sectional view of roller 518 taken generally along line 15-15 in FIG. 14. First tube 502 includes radial outwardly facing surface 536. Surface 536 includes stopping element 540 arranged to engage with plurality of teeth 538. Roller 518 includes plurality of teeth 538 arranged on a radially inwardly facing surface. Each tooth of plurality of teeth 538 are angled such that rotation of roller 518 in rotational direction RD1 causes each tooth to slide over and past stopping element 540 while preventing rotation of roller 518 in rotational direction RD2.
Thus it is seen that the objects of the invention are efficiently obtained, although changes and modifications to the invention should be readily apparent to those having ordinary skill in the art, which changes would not depart from the spirit and scope of the invention as claimed.
