DETAILED DESCRIPTION OF THE EMBODIMENTS
It is therefore desirable to provide a portable roller massager device capable of being made smaller without compromising the efficacy of the device.
The present disclosure provides in some embodiments a portable device for massaging and treating a person's muscles. The device may include an elongate center shaft and a roller section rotatably positioned about the outer surface of the elongate cylindrical center shaft and extending at least a portion of a distance between a first end and a second end of the elongate center shaft. The device also includes a first handle member and a second handle member that are movably attachable to the first end and the second end. The handles allow manual operation of the portable roller massager for body massage, wherein the roller section may rotate around the elongate cylindrical shaft.
FIG. 1 illustrates a perspective view of an embodiment of a portable roller massager 100. The roller massager 100 includes an elongate center shaft 110 having an outer surface 115. The elongate center shaft 110 may also have a first end 111 and a second end 112, and a longitudinal axis extending between the first end 111 and the second end 112. Generally, the elongate center shaft 110 may be cylindrical in shape, as illustrated in FIG. 1. The elongate center shaft 110 may be formed from a plastic, metal, wood, or polymer tubing or solid rod, or any other material suitable for forming the elongate center shaft 110.
FIG. 1 also illustrates a roller section 120, rotatably positioned around the outer surface 115 of the elongate center shaft 110. The roller section 120 may extend from the first end 111 of the elongate center shaft 110 to the second end 112 of the elongate center shaft 110. Alternatively, the roller section 120 may extend only a portion of the elongate center shaft 110. The roller section 120 may be configured to rotate 360 degrees freely about the outer surface 115 of the elongate center shaft 110. However, any suitable range of rotation could also be used. The roller section 120 may take the form of multiple segments of uniform length, as illustrated in the embodiment in FIG. 1. Alternatively, the roller section 120 may have a unibody construction, segments having different lengths, or any other suitable construction (not shown). The outer surface of the roller section 120 may have a generally curved or cylindrical shape, but any suitable geometry may be used. The outer surface of the roller section 120 may include a texture that may be in the form of ridges, as well as many other forms suitable for the purpose of treating a person's musculature. The texture may also be configured to cover all of or just a portion of the outer surface of the roller section 120. The roller section 120 may be formed from any suitable material such as foam, rubber, or any durometer plastic, or thermoplastic elastomer.
Also, as illustrated in FIG. 1, a first handle member 130 and a second handle member 140 may be movably attached to the first end 111 and second end 112 of the elongate cylindrical center shaft 110 of the roller massager 100. The first and/or second handle members 130 and 140 may be attached such that either one of the members may be easily removed or detached. A number of different forms of attachment may be used such as thread-to-connect, twist-to-connect, and push-to-connect. The first and second handle members 130 and 140 may also be held in place frictionally, or by any other means suitable for connecting them to the elongate center shaft 110. The shape of the first and second handle members 130 and 140 may be configured such that the roller section 120 is prevented from sliding off the elongate center shaft 110. The handle members 130 and 140 may be formed from any suitable material such as plastic, foam, or rubber. The handle members 130 and 140 may also include a textured outer surface in order to improve the user's grip on the roller massager 100.
The roller massager 100 may also include washers 117 at the first end 111 and second end 112 of the elongate center shaft 110. The washers 117 may be used to hold the roller section 120 on the elongate center shaft 110. In some embodiments, at least one of these washers 117 may be removed such that the roller section 120 may be exchanged for a different roller section.
A number of embodiments relating to the forms of connection between the elongate center shaft 110 and the first and second handle members 130 and 140 are described herein.
The first embodiment of connection is a thread-to-connect connection. FIG. 1 illustrates a perspective view of this connection, in which first end 111 and second end 112 each include male threads 151 and handles 130 and 140 include female threads 152 that fit onto the male threads of ends 111 and 112. FIGS. 2A and 2B illustrate, respectively, a side view and a cross section view in a plane 2B of FIG. 2A. FIG. 3 illustrates a close up perspective view. FIGS. 4A, 4B, and 4C illustrate, respectively, a perspective view and a cross section view, in a plane 4C of FIG. 4B, after the first and second handle members 130 and 140 have been connected to the elongate center shaft 110.
The first and second handle members 130 and 140 may be solid (not shown). Alternatively, they may be hollow, as shown in the aforementioned figures. The hollow handle members may offer a storage capability for the portable roller massager 100. More specifically, the first handle member 130 includes a hollow cavity that is sufficient to contain the elongate center shaft 110 and roller section 120, or part of them. The second handle member 140 includes a hollow cavity that is sufficient to contain the first handle member 130 (that already contains contain all or part of the elongate center shaft 110 and roller section 120), or a part of it. This allows the user to reduce the overall size of the portable roller massager 100 for the ease of carrying and storage. FIGS. 5A, 5B, and 5C illustrate, respectively a perspective view and a cross section view of the portable roller massager 100 after it has been reduced in size by first detaching the first and second handle members 130 and 140, and then using them to store the elongate center shaft 110. The cross section view of FIG. 5C is in a plane 5C of FIG. 5B.

FIG. 9 illustrates a close up perspective view of push-to-connect connection 800. FIG. 10 illustrates cross section views of push-to-connect connection 800 in a plane 10 of FIG. 9. Particularly, a spring loaded detent 651 on the elongate center shaft 110 snaps into a groove 652 in the first or second handle member 130 or 140. FIG. 11 illustrates a perspective view of after the first and second handle members 130 and 140 have been connected to the elongate center shaft 110. FIG. 12 illustrates cross section views after the first or second handle members 130 or 140 have been connected to the elongate center shaft 110 in the push-to-connect connection embodiment. The cross section views of FIG. 12 are in a plane 12 of FIG. 11.
An alternative embodiment of a portable roller massager 200 is illustrated in FIGS. 13, 14, 15, and 16. As shown in FIGS. 13 and 14, the portable roller massager 200 includes an elongate center shaft 210 having a first end 211 and a second end 212. Additional disclosure of these parts is similar to the disclosure of parts 110, 111, and 112 as described above. Also, a roller section 220 is rotatably positioned about the outer surface of the elongate center shaft 210. Additional disclosure of these parts is similar to the disclosure of part 120 as described above.
The roller massager 200 includes a first handle member 230 and a second handle member 240, as shown in FIG. 13. The first handle member 230 and the second handle member 240 are alternatively known as “captive handles” because they are not completely detached from the elongate center shaft 210. They are capable of being extended and collapsed, as they slide outward and inward, respectively. FIGS. 13 and 15 illustrate the first handle member 230 and the second handle member 240 in an extended position. FIGS. 14 and 16 illustrate the first handle member 230 and the second handle member 240 in a collapsed position. The cross section views of FIGS. 14 and 16 are in a plane 14 of FIG. 13. As an example shown in FIG. 14, the first handle member 230 covers at least a portion of the elongate center shaft 210 and the roller section 220, whereas the second handle member 240 covers at least a portion of the first handle member 230. The first handle member 230 and the second handle member 240 are capable of being locked into positions with the first end 211 and the second end 212 of the elongate center shaft 210 at connection interfaces, as illustrated in FIG. 15. These connection interfaces may be threaded, snap, twist, or any other means known in the art. Mechanical stops 231 prevent the first handle member 230 and the second handle member 240 from being completed detached from the elongate center shaft 210, as shown in FIGS. 14 and 15.
