The present disclosure relates generally to a massage device, for example, suitable for massaging the muscles of a person. The present disclosure relates more particularly to a device configured to move along one or more muscles so as to provide a massage.
Tightness in muscles or fascia can jeopardize a person's overall health. Such tightness can cause inflammation in the muscles, fascia and neighboring joints, which may lead to discomfort in the affected areas. Pain from muscle and fascia tightness in the ankles, knees, hips, back, and pelvis often affects posture, function, movement, strength, and endurance of the body.
Left untreated, tightness can lead to more serious injuries. For example, tightness of the iliotibial band (IT), calf, hamstrings, quadriceps, hip flexors, abductors and adductors can cause falls, tears and strains. In severe cases, treatment of the affected tissue may require injections or even surgery.
To reduce tightness in muscles and fascia, medical practitioners often recommend massaging the tight tissue to alleviate tension and thereby reduce inflammation. A popular method to reduce tightness, particularly in the back and legs, involves a person lowering herself to a horizontal position near the floor, placing the affected tissue on top of a ball or foam roller, and rolling the tissue back and forth over the ball or foam roller. Using his body weight, the person can press affected tissue onto the ball or foam roller and use the rolling motion to alleviate the tension. While this method can be affective, it has numerous drawbacks. First, adjusting the force applied to the tissue requires the person to hold a portion of his body weight off the floor. For many people, holding their body weight in this position is too strenuous, and they may be unable to maintain the position for the amount of time necessary to promote relief. Accordingly, many people will apply more pressure to the affected tissue than necessary, which can cause significant discomfort and pain.
An alternative method of alleviating tightness in muscles and fascia involves the use of a hand-held roller or other massage device that is moved by the user over the affected tissue. This method also has drawbacks, as it requires the user to contort her body in various positions. While the user is sitting or standing, she must compromise muscles in the torso by bending or twisting in order to reach the affected muscles. Further, it may be difficult in such a position to supply even pressure over the muscle, or even to reach the entirety of the muscle, which is often required to fully alleviate tension.
The present inventor has recognized that there is a need for a massage device that can target muscles and reduce tension more effectively and that is easier to use.

Additional aspects of the disclosure will be evident from the disclosure herein.
The accompanying drawings are included to provide a further understanding of the methods and devices of the disclosure, and are incorporated in and constitute a part of this specification. The drawings are not necessarily to scale, and sizes of various elements may be distorted for clarity. The drawings illustrate one or more embodiment(s) of the disclosure, and together with the description serve to explain the principles and operation of the disclosure.
As described above, the present inventor has noted that conventional massage devices and methods can be difficult to use and, even when effective, can lead to other problems. The present inventor has developed a massage device that is easier to use and can effectively massage muscles and other tissue without compromising proper form and without discomfort or fatigue.
Accordingly, one aspect of the disclosure is a vertical leg massage device including a vertical track, a carriage coupled to the vertical track, a massage component disposed on the carriage, and a drive that is connected to the carriage and configured to move the carriage along the vertical track. Such a massage device is shown in
In certain embodiments as otherwise described herein, the vertical track is straight. For example, track 110 is a straight track and allows movement of carriage 130 in only two opposing directions, namely up and down. In particular, track 110 is aligned with gravity such that carriage 130 is confined to a vertical axis as it travels along the track. In other embodiments, the track includes small curves in order to match the contours of a person's body. In such an embodiment, the carriage still moves substantially along the direction of a straight axis, yet the carriage can deviate from that axis in the location of the curves. For example, in certain embodiments, a lower portion of the track includes a shallow concave curve to accommodate a user's calf. In other embodiments, an upper portion of the track includes a convex curve to accommodate a user's lower back. In still other embodiments, the track includes multiple small curves corresponding to various contours of the user's body.
In certain embodiments, the vertical track is a section of a longer track with additional curves. For example, the vertical track may be a vertical section of a track that also includes horizontal components on either or both ends of the vertical section. For example, these sections may be used for mounting the track to a support surface and be inaccessible to the carriage. Or the carriage may travel along these curved sections, which are used for massaging other parts of the user's body.
The term vertical, as used herein, refers to a direction that is substantially aligned with the direction of gravity. In some embodiments, an axis of the vertical track is within 30 degrees of the direction gravity, for example, within 15 degrees, within 5 degrees or even within 2 degrees of the direction of gravity.
In certain embodiments as otherwise described herein, the track includes at least one rail, and the carriage includes rollers that secure the carriage on the rail and allow rolling interaction between the carriage and the rail as the carriage moves along the track. For example, track 110 includes rail 112 with a hollow interior. Rail 112 includes a riding surface 114 and outwardly extending flanges 116 on opposing lateral sides of track 110 (shown in
As will be understood by a person of ordinary skill in the art, the carriage and rail can have various configurations of flanges, stabilizing legs and rollers to secure the carriage to the track while allowing the carriage to move smoothly thereon. For example, while the carriage 130 in massage device 100 wraps around a portion of track 110 and has stabilizing components that engage an outer surface of the track, in other embodiments the carriage includes stabilizing components that are disposed inside the track, such that the track wraps around the carriage.
In certain embodiments as otherwise described herein, the track includes a rod that extends through an opening in the carriage. For example, massage device 400, shown in
To secure the rods 412, 414, track 410 further includes upper and lower receiving structure 416, 418 that hold the respective ends of rods 412 and 414 in place. Lower receiving structures 418 is a single structure that includes an aperture allowing portions of drive 460 to pass therethrough. In other embodiments, the lower receiving structure can be formed by separate components that receive each rod of the track individually.
In certain embodiments as otherwise described herein, the track is disposed on a structural support and the track is moveable in a vertical direction along the structural support. For example, in massage device 500, shown in
In certain embodiments as otherwise described herein, the drive includes an electric motor that imparts movement of the carriage along the track. For example, in massage device 100, shown in
In certain embodiments the electric motor has a power rating in a range of 0.1 to 0.5 horsepower, for example 0.2 to 0.3 horsepower, for example about 0.25 horsepower. Such a power rating is sufficient to move the carriage with a force applied against the massage component within a normal operating range. In certain embodiments, the electric motor has a greater or smaller power rating.
In certain embodiments as otherwise described herein, the drive includes a wheel coupled to the electric motor and a belt or chain engaging the wheel. The wheel is configured to be driven by the electric motor. The belt or chain is disposed in a loop that spans the height of the vertical track. Further, the carriage is mounted on the belt or chain so as to move up or down along the vertical track as the belt or chain is driven by rotation of the wheel. For example, linkage 164 in massage device 100 includes a wheel 166 in the form of a sheave that is coupled to a belt 168. In other embodiments, the wheel is a sprocket or gear and the linkage includes a toothed belt or a chain. A portion of belt 168 is attached to carriage 130 so that conveyance of belt 168 by sheave 166 moves carriage 130. In order for belt 168 to drive the movement of carriage 130 along the entire height of track 110, the belt extends upward to span the length of the vertical track. Belt 168 spans the length of track 110 in that it extends from an area at the bottom of track 110 to an area at the top of track 110.
In some embodiments, the loop that includes the belt or chain has a uniform construction along its length. For example, the entire loop is in the form of a toothed belt. In other embodiments, the belt or chain is confined to a portion of the loop and the remaining portion of the loop is provided by a tension line, such as a cord. With movement of the carriage being confined to length of the track, in many embodiments there is no need for the entire loop to engage the wheel. Accordingly, in some embodiments the belt or chain portion of the loop is confined to a certain section.
In certain embodiments as otherwise described herein, the drive includes a screw coupled to the electric motor and configured to be rotated by the electric motor. The screw spans a height of the vertical track and a rotationally fixed nut is configured to move up and down with rotation of the screw. The carriage is attached to the nut such that movement of the nut correlates to movement of the carriage. For example, the linkage 664 of massage device 600, shown in
In certain embodiments as otherwise described herein, the drive includes a pinion mounted on the carriage and coupled to the electric motor. The pinion is configured to be rotated by the electric motor. The drive also includes a rack spanning the height of the vertical track that is engaged by the pinion such that rotation of the pinion moves the pinion along the rack thereby imparting motion to the carriage along the vertical track. A massage device including such a drive is shown in
In certain embodiments as otherwise described herein, the drive includes an electric motor that is mounted to the carriage so as to move with the carriage along the track. For example, electric motor 762 is attached to carriage 730. As electric motor 762 turns pinion 766, thereby causing the pinion to move along rack 764, the electric motor and carriage move together along track 710. In other embodiments, the electric motor is fixed in place. For example, in massage devices 100, 400, 500 and 600, the electric motors are fixed in place. As will be appreciated by those of ordinary skill in the art, the electric motors may be attached to a support structure such as the floor or a wall using fastening mechanisms or other attachment configurations.
In certain embodiments as otherwise described herein, portions of the drive are encompassed within an opening in the track. For example, in massage device 100, belt 168 passes through a channel formed by hollow interior 124 within rail 112 (see
In certain embodiments as otherwise described herein, the massage component includes a roller that is rotatably coupled to the carriage. For example, the massage component 140 of massage device 100 includes roller 142. Carriage 130 includes two arms 135 that hold opposing ends of roller 142 through a rotatable engagement, as will be appreciated by those of ordinary skill in the art, for example using bearings. Arms 135 allow roller 142 to rotate about an axis that is perpendicular to the axis of movement along track 110.
In certain embodiments as otherwise described herein, the roller is cylindrical and rotates about a central axis of the cylindrical shape. In such an embodiment, the peripheral surface 144 of the roller curves around the axis of rotation, but is straight along the length of the axis of rotation. For example, roller 142 in massage device 100 in cylindrical in shape. In other embodiments the roller includes an outer surface that includes curves both around the axis of rotation and along the axis of rotation. For example, in some embodiments the roller is spherical in shape. In other embodiments the roller has an undulating surface such that the roller has a varying diameter along the length of the axis of rotation.
In certain embodiments as otherwise described herein, the roller includes a peripheral surface formed of a complaint material. As will be appreciated by those of ordinary skill in the art, the material may have a stiffness that is high enough to provide a massaging force when applied to soft tissue, but low enough to yield when applied to bones or other harder tissue.
In certain embodiments as otherwise described herein, the complaint material is one of a closed-cell foam, a polyethylene foam, polystyrene, ethylene-vinyl acetate, rubber, synthetic rubber, or neoprene.
In certain embodiments as otherwise described herein, the peripheral surface of the roller includes a surface texture. In some embodiments the surface texture includes a series of protrusions or ridges arranged around the peripheral surface. The protrusions and ridges may be formed in a variety of different shapes, having a rounded or polygonal cross section. In certain embodiments the ridges extend along the length of the roller, while in other embodiments the ridges extend circumferentially around the roller. Still in other embodiments, the ridges extend along a helical path. In some embodiments the surface texture includes ridges and protrusions. For example, roller 842, shown in
In certain embodiments as otherwise described herein, the roller is freely rotatable. As such, any portion of the roller surface that contacts the user's body will roll against the user, thereby reducing friction between the user's body and the roller. Further, when the roller includes a surface texture, the textured components will be pressed into a specific location of the user's body and massage the targeted tissue, rather than rubbing against the user.
In certain embodiments as otherwise described herein, the roller includes an outer layer surrounding a core. In some embodiments, the core is hollow. In certain embodiments, the roller includes an outer layer formed of a compliant first material that surrounds an inner core of a second material, where the first and second materials are different. In certain embodiments the core is solid, while in other embodiments the core is a hollow shell. For example, roller 942 includes outer layer 948 and inner core 950, which is formed as a hollow shell.
In certain embodiments as otherwise described herein, the inner core is harder than the compliant material of the outer layer. As will be appreciated by those of ordinary skill in the art, the core can formed from a variety of different materials including polyvinyl chloride (PVC), polyphenylene, polycarbonate, polyethylene, polypropylene, polystyrene, polyurethane, metal (e.g., aluminum), or combinations thereof.
In certain embodiments as otherwise described herein, the roller includes a vibration motor. In some embodiments, the vibration motor is an eccentric rotating mass vibration motor. For example, roller 942 includes such an eccentric rotating mass vibration motor, which includes an eccentric mass 954 that is coupled to motor 956. As the motor rotates the eccentric mass, a vibration is imparted to the roller, as will be appreciated by those of ordinary skill in the art.
In certain embodiments, the roller includes a sheathing of fabric. As used herein, the term fabric includes textiles and sheet material commonly used in place of textiles, such as leather or synthetic leather. In some embodiments the sheathing is elastic so as to form a tight fit over the peripheral surface of the roller. For example, roller 942 includes sheathing 958 surrounding outer layer 948. In some embodiments, the sheathing is removable from the rest of the roller. Such a removable sheathing allows the roller to be kept clean by allowing easy laundering of the sheathing.
In certain embodiments, the massage component includes an actuator and a first massage head coupled to the actuator. The actuator is configured to move the first massage head in a path with respect to the carriage. The term actuator as used herein includes any component that imparts motion to another component. For example, in certain embodiments, the actuator is a motor. In other embodiments, the actuator is a hydraulic cylinder or a pneumatic cylinder. A massage device with such a massage component is shown in
In certain embodiments as otherwise described herein, the path of the massage heads includes an elliptical component in a plane that is parallel to the axis of the vertical track. For example, massage heads 1044 move in a circle with the rotation of rotatable wheels 1045. Also, massage heads 1244 of massage device 1200 are moved by actuators 1242 in the elliptical paths shown in dashed lines in
In certain embodiments as otherwise described herein, the carriage includes opposing lateral sides and a centerline that is aligned with an axis of the vertical track. The path of one or more of the massage heads crosses the centerline of the carriage. For example, the center massage head 1044 of massage device 1000 moves on a path that crosses the centerline 1033 of carriage 1030. The massage heads of massage device 1200 also move along such a path. For example, carriage 1230 includes lateral sides 1231 and a centerline 1233, which is shown as a dashed line in
In certain embodiments as otherwise described herein, the carriage includes a fabric that covers the massage heads included in the massage component. For example, carriage 1030 includes a fabric cover 1039 disposed over the massage heads 1044. Likewise, carriage 1230 includes a fabric cover 1239 that is disposed over the massage heads 1244. The cover prevents the massage heads from coming into direct contact with a user and possibly rubbing the user's skin. The cover also protects the components of the actuator and hides any possible pinch points.
In certain embodiments, the carriage includes a vibration motor. For example, the carriage may include an eccentric rotating mass vibration motor as described above.
In certain embodiments as otherwise described herein, the vertical leg massager further includes a base and the vertical track is supported by the base. For example, massage device 1400, shown in
In certain embodiments as otherwise described herein, the base includes rollers to allow movement of the base. In some embodiments, the base includes a support structure, and the rollers are mounted on springs such that a downward force applied to the base depresses the springs and places the support structure in contact with an underlying surface. For example, base 1480 includes rollers 1485 that are mounted to a support structure 1488 via springs 1486. When a force is applied to the platform 1482 of the base, the springs 1486 compress bringing support structure 1488 into contact with an underlying surface, such as the floor, as depicted in
In certain embodiments as otherwise described herein, opposing upper and lower ends of the vertical track include mounting feet for securing the vertical track to a vertical support structure. For example, massage device 100 in

Examples of such buttons include: an up button that controls the drive to move the carriage up, a corresponding down button, an isolation button configured to hold the carriage in place or move the carriage up and down through a small height range, for example no more than 4 inches, no more than 3 inches, or no more than 2 inches, a reciprocate button configured to move the carriage up and down over the entire path of the track, and an off button to stop the carriage and any moving massage heads.
A massage device including a controller with a remote is shown in
In certain embodiments as otherwise described herein, the controller includes a memory for storing instructions and a processor to carry out the instructions. For example, in some embodiments the controller includes instructions for carrying out a massage sequence. The massage sequence can include various movements of the carriage along the track, or movements of any massage heads included in the massage component, as will be appreciated by those of ordinary skill in the art. For example, in certain embodiments including massage heads, the massage sequence includes instructions for moving the massage heads in different ways, for example in a tapping, kneading or rolling motion. In some embodiments the massage sequence includes reciprocating the carriage between upper and lower limits. In some embodiments, the upper and lower limits are input by the user, in other embodiments, a target area is input by the user and the upper and lower limits of the reciprocation are pre-programmed. For example, the user inputs a target area and the controller operates the drive to reciprocate the carriage within a 3 inch range surrounding the target area.
In certain embodiments, the massage device includes electrical connections between the controller and components of the drive, such as an electric motor. In some embodiments, these electrical connections are hidden as will be appreciated by those of ordinary skill in the art, for example by passing through conduits within the track. In other embodiments communication between the controller the drive is carried out through a wireless data connection.
Another aspect of the present disclosure is a massage method comprising providing a vertical massager including a vertical track, a carriage coupled to the vertical track, a massage component disposed on the carriage, and a drive connected to the carriage and configured to move the carriage along the vertical track.
