[0039] The present application is directed, at least in part, to a device having a rotating element that provides or treats muscle pain, myofascial pain, trigger points, and the like. In embodiments, the device may include a first handle and a second handle that are grasped or otherwise held by a user. A rotating assembly is rotatably coupled around the first handle or the second handle, and the rotating element may be coupled to a frame of the rotating assembly. For example, the frame of the rotating assembly may define an axis (e.g., an axis, a rod, etc.) between the first handle and the second handle, and each rotating element is arranged around these axes. The device includes one or more motors that, when actuated, rotate the rotating assembly. The rotating element may rotate accordingly around the longitudinal axis (or axis of rotation) of the device. In embodiments, the device may be used with bare hands so that the user may manipulate the device to / over certain parts of their body (e.g., legs, back, arms, etc.). In other embodiments, the device may be placed on / in a support, and wherein the user may manipulate their body on / above the device. Therefore, the device may be used in different ways to provide or treat muscle pain, myofascial pain, trigger points, and the like.

[0040] The device may include one or more input components, such as buttons, levers, toggle keys, switches, etc., that control the speed of the motor. For example, depending on the desired degree of relief, the motor can be operated at different speeds to rotate the rotating assembly. In an embodiment, buttons, levers, switches, etc. can receive different types of inputs to change the speed of the motor. For example, pressing and holding the button for a first time period (e.g., one second) can cause the motor to operate at a first speed, pressing and holding the button for a second time period (e.g., two seconds) can cause the motor to operate at a second speed different from the first speed, and so on. In an embodiment, the motor can be configured to operate at any number of speeds (e.g., one, two, four, five, ten, etc.). In addition, the button can be pressed a certain number of times to change or set the speed, rather than providing different inputs in different time periods. For example, pressing the button once can cause the motor to operate at a first speed, pressing the button twice (e.g., continuously) can cause the motor to operate at a second speed, and so on.

[0041] In addition to buttons, levers, toggle keys, switches, etc. for controlling the speed of the motor, buttons, levers, switches, etc. can also be used to turn on / off the device, the rotational movement of the device, and other settings of the control device (e.g., heating, vibration, operating time, etc.). In an embodiment, the device may include an actuable mechanism (e.g., a safety button, lever, toggle key, switch, etc.) that is first (e.g., before) actuated to change, adjust, or set the speed of the motor. For example, in order to control the speed of the motor, a first button can be pressed, and while pressing the first button, a second button can be used to control the speed of the motor. For example, this can prevent accidental operation of the device. However, once the speed of the motor is set, the first button and / or the second button can be released so that the user does not have to continue pressing the first button and / or the second button. In an embodiment, buttons, levers, switches, etc. can be located on the first handle and / or the second handle. Although described as including two buttons, the device can include more or less than two buttons.

[0042] In embodiments, the device may include an output component, such as a lighting element, a speaker, and the like. The lighting element may output an indication of the motor speed and / or other settings of the device. For example, if the motor includes five speeds and the user has selected a second speed, the lighting element may output such an indication. In embodiments, the device may include a light bar, a light ring, a series of lights, and the like that illuminate to indicate the speed of the motor. In other embodiments, the speaker may output an indication of the speed (e.g., low, medium, high, etc.). Of course, it should be understood that the output component may output other indications related to additional or alternative settings of the device.

[0043] The rotating assembly may include a first frame (e.g., a section, a segment, a part, a half, etc.) and a second frame (e.g., a section, a part, a half, etc.). In an embodiment, each of the first frame and the second frame may form a portion (e.g., a length) of an axis around which the rotating element is disposed. For example, the first frame may include a first base, and the first column may extend from the first base. The second frame may include a second base, and the second column may extend from the second base. When the rotating assembly is assembled, the first column and the second column may be aligned to form an axis. In other words, the first column may form a first length of the axis, and the second column may form a second length of the axis. The first frame and the second frame may be coupled together using fasteners, snap fits, press fits, etc. However, in an embodiment, before the first frame and the second frame are coupled together to form an axis, the rotating element may be slid onto the first frame (e.g., onto the first column), and the second frame (or the second column) may be slid through the rotating element to align, mate, or couple with the first frame. In an embodiment, once assembled, the rotating assembly may be slid onto the first handle, and the second handle may be coupled to the first handle therein. When assembled, the rotating assembly may be disposed or connected between the first handle and the second handle. However, although described as including two handles, in embodiments, the device may include a single handle or more than two handles.

[0044] In an embodiment, the rotating assembly may include a gear that engages with a gear of the motor (or is operably coupled to the motor). For example, the first base and / or the second base may include a ring gear that is engaged by one or more internal spur gears disposed in the first handle or the second handle. During the actuation of the motor and the rotation of the one or more internal spur gears, the movement is transmitted to the rotating assembly via the engagement between the one or more internal spur gears and the ring gear. In an embodiment, the rotating assembly may be mounted on one or more bearings (e.g., roller bearings) to allow the rotating assembly to rotate. For example, the first end of the rotating assembly (e.g., the first base) may be mounted to the first handle via a first gear, and the second end of the rotating assembly (e.g., the second base) may be mounted to the second handle via a second gear. In addition, in an embodiment, the first end of the rotating assembly (e.g., the first base) may be mounted to the first handle via a first bearing, and the second end of the rotating assembly may be mounted to the second handle via a second bearing. In an embodiment, the motor may be mounted or otherwise disposed in the first handle. Therefore, in an embodiment, the first handle may include one or more spur gears for engaging with the ring gear. Although described as including certain types of gears, such as ring gears and spur gears, other gears may also be envisioned. The first handle may also include one or more holes to allow airflow through the first handle to cool or dissipate heat generated by the motor.

[0045] In an embodiment, the rotating assembly can be interchangeable with other rotating assemblies. For example, each rotating assembly has a specific profile or shape of the rotating element, and interchanging the rotating assemblies can provide rotating elements with different profiles and shapes. In an embodiment, the size of the rotating assembly can vary. In addition, the rotating elements can be interchangeable with each other instead of replacing the rotating assembly.

[0046] In an embodiment, the rotating element may include a plurality of first rotating elements and a plurality of second rotating elements. The first rotating element may include a first structural feature (e.g., ribs, protrusions, textures, etc.), and the second rotating element may include a second structural feature (e.g., ribs, protrusions, textures, etc.) that is different from the first structural feature. In an embodiment, the first structural feature and the second structural feature may be complementary because the first structural feature and the second structural feature are interlocked, interwoven, etc. For example, each of the first rotating element and the second rotating element may have a first end and a second end spaced apart from the first end along its length. Between the first end and the second end, the outer surface of the first rotating element and the second rotating element may undulate to form peaks and valleys. Here, the cross-sectional dimensions of the first rotating element and the second rotating element may vary along the length of the first rotating element and the second rotating element, respectively.

[0047] When coupled to the first frame and the second frame, the undulating surfaces of the first rotating element and the second rotating element can be offset from each other so that the peaks of the outer surface formed in the first rotating element are matched, located, arranged or received in the valleys of the surface formed in the outer surface of the second rotating element. However, although the first rotating element and the second rotating element are described as having undulating surfaces, in embodiments, the first rotating element and the second rotating element may include other surfaces and / or have different shapes. For example, the first rotating element and the second rotating element may include different surface finishes, shapes, contours, etc. to provide or treat muscle pain, myofascial pain, trigger points, etc. In addition, in embodiments, the first rotating element and the second rotating element may be made of a single piece of material, or may include multiple pieces of material.

[0048] The first handle and / or the second handle may also include various brackets, mountings, etc. to receive the components of the device respectively to align or otherwise orient the components within the first handle and the second handle. Suitable manufacturing techniques for forming the device include injection molding, extrusion, casting, etc. The device or its components may also be made of metal (e.g., aluminum), plastic, composite materials, and / or any combination thereof. The rotating element may be made of low-density foam or rubber material, but other compressible materials may also be used. In an embodiment, the rotating element may include closed-cell foam, such as ethylene vinyl acetate ("EVA") foam. In an embodiment, the hardness rating of the rotating element may be between about 0.40 and about 60.

[0049] In an embodiment, the device may include a bracket or be used with a bracket. For example, the bracket may include a first container for receiving at least a portion of a first handle and a second container for receiving at least a portion of a second handle. The first container may engage with the first handle, and the second container may engage with the second handle to prevent (e.g., maintain) the first handle and the second handle during operation of the device. The first container and the second container may be formed in and between the pillars of the bracket, and the bracket may form a groove. The size of the groove is suitable for receiving a rotating assembly (including a rotating element) so that the device can operate when placed on the bracket. For example, when the first handle is disposed in the first container and the second handle is disposed in the second container, the rotating assembly can be allowed to rotate in the groove (e.g., between the first container and the second container).

[0050] In an embodiment, the first handle or the second handle can be configured to provide a stand or column for the device. For example, the first handle and / or the second handle can be rotated to set the rotating assembly above the ground. The first handle and the second handle can then be rotated backward during use. A ball joint, a knuckle joint, etc. can provide such movement.

[0051] In addition to the above components, the device may also include various components that allow it to operate. For example, the device may include various hardware components (e.g., processors, memory, printed circuit boards (PCBs), printed circuit board assemblies (PCBAs), etc.), sensors (e.g., temperature, force, pressure, resistance, etc.), batteries, ports (e.g., charging, auxiliary, USB-C), network interfaces that allow connection to one or more devices (e.g., phones, tablets, computers, etc.), heat dissipation elements, etc. In an embodiment, the device may be configured to continuously adapt based on sensed conditions. For example, a sensor may measure the current (e.g., consumption) on a motor during use. For example, if a user changes the amount of force that presses the device against their body (e.g., legs, arms, etc.), thereby reducing the speed of a rotating assembly (or motor), the device may sense this reduction. If the current on the motor is greater than a threshold value within a threshold time period, the device may cause an increased current to be supplied to the motor to increase its speed. By doing so, the user is able to apply the device to their body with a given force without sacrificing the rotational speed of the rotating assembly. After removing the device, there is less resistance to the motor, so the motor can rotate at a higher speed. However, if the current on the motor is less than the threshold value for a threshold period of time, the device may cause the current supplied to the motor to be reduced to reduce its speed.

[0052] Although the device is described as including certain components, or certain parts are arranged in certain components, other variations are contemplated. For example, the device may include more or less than three components, and / or a component may include different parts than described.

[0053] The present disclosure provides an overall understanding of the principles of the structures, functions, devices and systems disclosed herein. One or more examples of the present disclosure are shown in the accompanying drawings. It will be understood by those skilled in the art that the devices and / or systems specifically described herein and illustrated in the accompanying drawings are non-limiting embodiments. Features described or described in conjunction with one embodiment may be combined with features of other embodiments. Such modifications and variations are intended to be included within the scope of the appended claims.

[0054] Figure 1 An example device 100 according to an example of the present disclosure and an example bracket 102 configured to receive the device 100 are shown. In an embodiment, the device 100 may include a first handle 104 and a second handle 106 spaced apart from the first handle 104 (e.g., in the X direction). In an embodiment, the first handle 104 and the second handle 106 may be configured to be held by a user operating the device 100. For example, the user's first hand may grasp the first handle 104 and / or the user's second hand may grasp the second handle 106. However, although described as including the first handle 104 and the second handle 106, in an embodiment, the device 100 may include only a single handle, or may include more than two handles. In addition, the first handle 104 and / or the second handle 106 may include a shape different from that shown.

[0055] The device 100 may also include a rotation assembly 108 disposed between the first handle 104 and the second handle 106. During operation, the rotation assembly 108 may rotate about the first handle 104 (or its housing) and / or the second handle 106 (or its housing) or a central axis extending through the device 100. For example, the rotation assembly 108 may rotate between the first handle 104 and the second handle 106 (e.g., about the X-axis). During the rotation, in an embodiment, the first handle 104 and / or the second handle 106 may remain stationary. As will be explained herein, the rotation assembly 108 may include a plurality of rotation elements 110, such as a first rotation element 110(1) and a second rotation element 110(2). The first rotation element 110(1) and the second rotation element 110(2) may be alternately coupled to the rotation assembly 108 or disposed on / around the rotation assembly 108 (e.g., about the X-axis). For example, the first rotation element 110(1) and the second rotation element 110(2) may alternate with each other around the rotation assembly 108. As will be further explained herein, the first rotating element 110(1) and the second rotating element 110(2) may include different surfaces, curves, textures, etc., so as to interweave, interlock, interlace, etc. with each other. In an embodiment, the outer surfaces of the first rotating element 110(1) and the second rotating element 110(2) undulate along at least a portion of the length of the first rotating element 110(1) and the second rotating element 110(2), respectively.

[0056] In an embodiment, the device 100 includes a first button 112 (e.g., a toggle key, a switch, etc.) that at least partially controls the operation of the device 100. For example, as will be explained herein, the motor can be operably coupled to the rotating assembly 108 to impart motion to the rotating assembly 108. For example, the first button 112 can control the speed of the motor. In an embodiment, the first button 112 can be pressed for different time periods and / or different times to control the speed of the motor. For example, pressing and holding the first button 112 for a first time period (e.g., one second) can cause the motor to operate at a first speed, pressing and holding the first button 112 for a second time period (e.g., two seconds) can cause the motor to operate at a second speed different from the first speed, and so on. Additionally or alternatively, the first button 112 can be pressed a certain number of times to change or set the speed, rather than providing different inputs in different time periods. For example, pressing the first button 112 once can cause the motor to operate at a first speed, pressing the first button 112 twice (e.g., continuously) can cause the motor to operate at a second speed, and so on. In embodiments, the motor can be configured to operate at any number of speeds (e.g., one, two, four, five, ten, etc.). As shown, a first button 112 can be located on the first handle 104. In embodiments, the first button 112 represents a mechanical button, a resistive button, a capacitive button, etc. In addition, although described as a button, the first button 112 can represent a switch, lever, knob, etc. that can be pressed, turned, or otherwise actuated.

[0057] In an embodiment, the device 100 can be operated in a first mode without the support 102 and in a second mode with the support 102. For example, in the first mode, the device 100 can be used barehanded so that the user can manipulate the device 100 to a part of their body (e.g., legs, back, arms, etc.). In the second mode, the device 100 can be placed on / in the support 102, and wherein the user can manipulate their body on / over the device 100 while the device 100 rests on the support 102. Details of the support 102 are described herein, however, the support 102 can include a first container 114 for receiving a portion of the first handle 104 and a second container 116 for receiving a portion of the second handle 106. The first container 114 can engage with the first handle 104, and the second container 116 can engage with the second handle 106 to prevent (e.g., retain) the first handle 104 and the second handle 104 during operation of the device 100. The groove 118 (e.g., cavity, recess, etc.) can accommodate the rotating assembly 108 (and the rotating element 110). The bracket 102 may also include additional voids, cavities, receptacles, etc. to receive the first handle 104 , the second handle 106 , or more generally, additional portions of the device 100 .

[0058] Figure 2The device 100 is shown disposed on, in, or within a support 102 according to an example of the present disclosure. As shown, the first handle 104 can be at least partially received within the first container 114, and the second handle 106 can be at least partially received within the second container 116. In addition, the rotating assembly 108 is disposed between the first container 114 and the second container 116 within the groove 118. There is a clearance distance between the bottom surface 200 of the groove 118 and the rotating assembly 108 (or the rotating element 110) to allow operation of the device 100. That is, the device 100 can be as shown. Figure 2 The device 100 is operated as shown (i.e., on the support 102), thereby allowing the rotating assembly 108 to rotate (e.g., about the X-axis) via actuation of the motor. During the rotation of the rotating assembly 108, the first handle 104 and the second handle 106 remain stationary. Compared to the freehand use of the device 100, the operation of the device 100 with the support 102 allows the user to manipulate (e.g., roll), place or rest their body parts on the rotating element 110 to provide myofascial pain relief.

[0059] As will be explained herein, the device 100 may include a safety button that is actuated (e.g., before) to operate the device 100. For example, in order to adjust the speed of the motor (e.g., by the first button 112), the second button may be pressed first. In other words, pressing the first button 112 without pressing the second button may limit the operation of the device 100. However, pressing the second button, and pressing the first button 112 while continuing to press the second button, may allow the operation of the device 100. After pressing the first button 112 (while pressing the second button), the second button may be released so as to operate the device 100 without continuing to press the second button. However, in an embodiment, the second button may be continuously pressed to operate the device 100. When placed in the bracket 102, the second button may be pressed by the bracket 102 (e.g., in the Y direction). More specifically, the second button may be pressed via engagement within the bracket 102, such as within the first container 114 or the second container 116. In an embodiment, the second button may be located on a side / surface of the first handle 104 opposite to the first button 112.

[0060] Figure 3 A top view of a device 100 according to an example of the present disclosure is shown. In an embodiment, the device 100 extends between a first end 300 and a second end 302. The first handle 104 can be disposed at or define the first end 300, and the second handle 106 can be disposed at or define the second end 302. A rotation assembly 108 including a first rotation element 110(1) and a second rotation element 110(2) is at least partially disposed between the first handle 104 and the second handle 106.

[0061] The first handle 104 includes a first button 112. In addition, the first handle 104 (or its housing) may include a lighting element that outputs light through one or more holes 304. For example, the one or more holes 304 are shown as including five holes. In an embodiment, the lighting element can output an indication of the motor speed and / or other settings of the device 100 via the holes 304. For example, the motor may include five speeds, and if the user selects the second speed, the second hole in the holes 304 can output light from the lighting element located below it. If the user selects the fourth speed, the fourth hole in the holes 304 can output light from the lighting element located below it. Therefore, the holes 304 can be used to indicate the operating state or condition of the device 100. However, although five holes 304 are described, the device 100 may include more or less than five holes 304. In addition, the location of the holes 304 on or around the device 100 may be different from that shown. Nevertheless, the device 100 may include a light bar, a display screen, or other components instead of having holes 304 to indicate the speed of the motor, or more generally indicate the settings of the device 100.

[0062] Figure 4 A bottom view of the device 100 according to an example of the present disclosure is shown. As described above, the first handle 104 may include a second button 400 (e.g., a toggle key, a switch, etc.). In an embodiment, pressing the second button 400 may allow the first button 112 to be used to control the actuation of the motor, thereby controlling the rotation of the rotating assembly 108. In other words, the second button 400 may be pressed (or otherwise actuated) first, and therein, the first button 112 may be pressed (or otherwise actuated) to control the rotation of the rotating assembly 108. In an embodiment, after the first button 112 is used to rotate the rotating assembly 108, the user may release the first button 112. In an embodiment, the second button 400 may be continuously pressed to allow operation of the device 100. That is, if the second button 400 is released after the rotating assembly 108 rotates, the rotating assembly 108 may stop rotating. In order to subsequently operate the device 100, the second button 400 may be pressed first, and then the first button 112 may be pressed to the desired speed. However, as described above, the second button 400 can be pressed when placed on the bracket 102. In an embodiment, the second button 400 represents a mechanical button, a resistive button, a capacitive button, etc. In addition, although described as a button, the second button 400 can represent a switch, a lever, a knob, etc. that can be pressed, turned, or otherwise actuated.

[0073] Figure 7 An example according to the present disclosure is shown along Figure 5B A cross-sectional view of the device 100 taken along line AA.

[0074] The device 100 includes a battery 700 and a motor 702 for transmitting motion to the rotating assembly 108. In an embodiment, the battery 700 and the motor 702 are disposed within the first housing 506 and / or the second housing 508, or within an assembly formed by the first housing 506 and the second housing 508. The device 100 may also include a gearbox 704 for coupling to the motor 702. The gearbox 704 or its gears may engage with the rotating assembly 108 to transmit motion from the motor 702 to the rotating assembly 108. The third housing 510 and the fourth housing 512 or an assembly thereof may be coupled to the first housing 506 and the second housing 508 or an assembly thereof via a rod 706. As will be explained herein, the rotating assembly 108 may be rotatably mounted around the rod 706 via a bearing 708.

[0075] The rotating assembly 108 may include an axis 710, which is at least partially formed by a first column 712 and a second column 714. The rotating elements 110 may be disposed around the axis 710, respectively. As will be explained herein, in an embodiment, the rotating assembly 108 may be at least partially formed by a first frame 716 and a second frame 718, wherein the first frame 716 and the second frame 718 are coupled together to form a frame, a body, etc. of the rotating assembly 108. The first column 712 may extend from the first frame 716 (e.g., in the X direction) (or be a part of the first frame 716), and the second column 714 may extend from the second frame 718 (or be a part of the second frame 718) (e.g., in the Y direction). The respective first column 712 may be coupled with the respective second column 714 to form the axis 710, about which the rotating elements 110 are disposed.

[0076] Figure 8 An example according to the present disclosure is shown along Figure 4 1 is a cross-sectional view of the device 100 taken along line BB. Figure 8 The illustrated view shows the first column 712 of the first frame 716, such as the first base 800 in the first frame 716. The rotating element 110 is hidden to show the gearbox 704 and the first frame 716 in detail.

[0077] The gearbox 704 may include at least a first gear 802, a second gear 804, and a third gear 806. The first gear 802 may be operably coupled to the motor 702 via a shaft 808. During actuation of the motor 702, the shaft 808 may rotate in a first direction (e.g., clockwise around the X-axis). Accordingly, the first gear 802 may rotate in a first direction. At the same time, the second gear 804 and the third gear 806 engaged with the first gear 802 may rotate in a second direction (e.g., counterclockwise around the X-direction). The second gear 804 and the third gear 806 may transfer motion to the rotating assembly 108 via the rotation of the first frame 716. In other words, in an embodiment, the rotating assembly 108 may be driven from one end thereof compared to both ends (e.g., near the second handle 106). In an embodiment, the first base 800 (or the first frame 716) includes a fourth gear 810 engaged by the second gear 804 and the third gear 806. During the rotation of the second gear 804 and the third gear 806 in the second direction, the fourth gear 810 may rotate in the second direction.

[0078] In an embodiment, the first gear 802, the second gear 804, and the third gear 806 can represent spur gears. The first gear 802 can include fewer teeth than the second gear 804 and the third gear 806. In an embodiment, the first gear 802 can also include a smaller diameter than the second gear 804 and the third gear 806. In an embodiment, the second gear 804 and the third gear 806 can be the same. The first gear 802, the second gear 804, and the third gear 806 can remain stationary so as not to move laterally during the rotation of the rotating assembly 108. Meanwhile, the fourth gear 810 can represent a ring gear engaged by the second gear 804 and the third gear 806. As will be explained herein, a portion of the second gear 804 can extend through the first housing 506 to engage with the fourth gear 810 in a first position, and a portion of the third gear 806 can extend through the third housing to engage with the fourth gear 810 in a second position opposite to the first position.

[0079] Although the illustrated gearbox 704 includes certain gears, and the illustrated first frame 716 includes certain gears, the gearbox 704, the first frame 716, and / or the second frame 718 may include different gears (e.g., bevel gears, worm gears, etc.), more gears than illustrated, gears of different sizes, etc. For example, although the gearbox 704 is illustrated as being engaged with the first frame 716 to transfer motion to the rotating assembly 108, the gearbox 704 may additionally or alternatively be engaged with the second frame 718 to transfer motion to the rotating assembly 108. The first frame 716 and the second frame 718 or the rotating assembly 108 may also be disposed around bearings to reduce friction and / or noise.

[0080] Fig. 9 A side view of the device 100 with the rotating assembly 108 removed according to an example of the present disclosure is shown. In an embodiment, the device 100 includes a first assembly 900 formed by a first housing 506 and a second housing 508, and a second assembly 902 formed by a third housing 510 and a fourth housing 512.

In an embodiment, the length of the first assembly 900 (e.g., in the X direction) may be greater than the length of the second assembly 902.

[0081] The first assembly 900 includes a housing 904, and the rotating assembly 108 is at least partially disposed around the housing 904. For example, the rotating assembly 108 can be disposed around the housing 904, but in an embodiment, it may not be engaged with the housing 904. The second gear 804 and the third gear 806 can be disposed through the housing 904 (e.g., the first housing 506 and the second housing 508) or an outer surface thereof to engage with the fourth gear 810 of the first frame 716. In addition, the first assembly 900 can include a first shaft ring 906 formed by the first housing 506 and the second housing 508, and the second assembly 902 can include a second shaft ring 908 formed by the third housing 510 and the fourth housing 512. There is a gap distance 910 between the first shaft ring 906 and the second shaft ring 908, and the rotating assembly 108 is received within the gap distance.

[0082] Although the device 100 is described as including the first component 900, the second component 902 and the rotating component 108, the device 100 may include more or less than the number of components described and shown. In addition, although certain components are described as being included in the first component 900, the second component 902 and the rotating component 108, other changes can be envisioned. For example, the motor 702 can be provided in a component other than the first component 900. In addition, although the first component 900 is described as including the first housing 506 and the second housing 508, the first component 900 may include more or less than two housings, and / or the housings may be different from those shown. For example, a single housing may form the first handle 104. Similarly, in an embodiment, although the second component 902 is described as including the third housing 510 and the fourth housing 512, the second component 920 may include more or less than two housings, and / or the housings may be different from those shown. For example, a single housing may form the second handle 106. In some cases, the first shell can form a portion (e.g., half) of the first handle 104 and a portion of the second handle 106, and the second shell coupled to the first shell can form another portion (e.g., half) of the second handle 104 and the second handle 106.

[0085] The first assembly 900 may include a first collar 906, which may be formed by respective portions of the first housing 506 and the second housing 508. For example, the first housing 506 may form a first half (e.g., a semicircle, a portion, etc.) of the first collar 906, and the second housing 508 may form a second half (e.g., a semicircle, a portion, etc.) of the first collar 906. The first cover 600 may be disposed on, around, etc. the first collar 906 to conceal fasteners for coupling the first housing 506 and the second housing 508 together.

[0086] In an embodiment, the first housing 506 and the second housing 508 can be coupled together using fasteners. For example, the fasteners can be arranged to pass through the second housing 508 and enter the first housing 506 to couple the first housing 506 and the second housing 508 together. The first housing 506 can include a first aperture 1004 to allow airflow through the first assembly 900 to dissipate heat from components (such as the motor 702 and the battery 700) within the first assembly 900. In addition, the second housing 508 can include a second aperture 1006 to allow airflow through the first assembly 900.

When the device 100 is assembled, the housing 904 may be disposed inside the rotating assembly 108 (or the first frame 716 and the second frame 718). Therefore, the rotating assembly 108 may be disposed around the outer surface of the housing 904. The first aperture 1004 and the second aperture 1006 may pass through corresponding portions of the first housing 506 and the second housing 508 that form the housing 904.

The rod 706 may also include a first passage 1504 through which a fastener may be disposed to couple the rod 706 to the third housing 510 and / or the fourth housing 512. Additionally, the rod 706 may include a second passage 1506 through which a fastener may be disposed to couple the rod 706 to the first housing 506 and / or the second housing 508. A bearing 708 may be disposed around the rod 706 at a location between the first end 1500 and the second end 1502. In an embodiment, the bearing 708 may be closer to the first end 1500 than to the second end 1502. The third shell 510 and the fourth shell 512 may further include a channel 1508 in which the rod 706 and the bearing 708 are disposed such that the first end 1500 extends to the outside of the third shell 510 and the fourth shell 512 to couple to the first shell 506 and / or the second shell 508 .

[0101] In an embodiment, the third housing 510 and / or the fourth housing 512 may include a groove or interlocking feature around the periphery of the third housing 510 and / or the fourth housing 512. For example, the groove may position the third housing 510 and the fourth housing 512 together, may prevent debris from entering the second component 902, may prevent liquid from entering the second component 902, and so on.

[0102] Fig.16 1504. The coupling of the first assembly 900 and the second assembly 902 according to an example of the present disclosure is shown. As shown, the first end 1500 of the rod 706 can be disposed in the first housing 506 and the second housing 508 via the passage 1206, and the second end 1502 can be disposed in the third housing 510 and the fourth housing 512 via the passage 1508. In addition, the rod 706 can be coupled to the first housing 506 and / or the second housing 508 via a fastener disposed through the second passage 1506, and the rod 706 can be coupled to the third housing 510 and / or the fourth housing 512 via a fastener disposed through the first passage 1504. The bearing 708 can also be disposed in the passage 1508 to allow the second handle 106 to rotate freely when the motor 702 is actuated.

[0103] Fig.17A and Fig. 17B A perspective view of a rotating assembly 108 according to an example of the present disclosure is shown. As will be explained herein, the rotating assembly 108 may be formed via or include a first frame 716, a second frame 718, a first rotating element 110(1), and a second rotating element 110(2). Fig.17A and Fig. 17BThe view in FIG. 1 shows the rotating assembly 108 being assembled. In this case, the first rotating element 110 (1) and the second rotating element 110 are arranged around an axis 710 formed by a first column 712 and a second column 714. The first column 712 can extend from a first base 800 of a first frame 716, and the second column 714 can extend from a second base 1700 of a second frame 718. The first base 800 can be configured to be at least partially disposed within a first flange 1106 adjacent to the first collar 906, and the second base 1700 can be configured to be at least partially disposed within a second flange 1404 adjacent to the second collar 908. In an embodiment, the first base 800 can be disposed adjacent to a first end 1702 of the rotating assembly 108, and the second base 1700 can be disposed adjacent to a second end 1704 of the rotating assembly 108 spaced apart from the first end 1702 (e.g., in the X direction).

[0104] The first base 800 is shown to include or define a fourth gear 810 for engaging with the second gear 804 and the third gear 806. In addition, the first base 800 can define a first race 1706 disposed on the collar 1104. During actuation of the rotating assembly 108, the first race 1706 can rotate about the collar 1104 (e.g., about the X-axis). The second base 1700 can define a second race 1708 that receives the bearing 708.

[0105] In an embodiment, the rotating assembly 108 can be interchangeable with other rotating assemblies 108. For example, each rotating assembly has a specific profile or shape of the rotating element 110, and interchanging the rotating assembly 108 can provide a rotating element 110 with a different profile and shape. In an embodiment, the size of the rotating assembly 108 can vary. In an embodiment, the rotating assembly 108 can slide onto or off the first assembly 900. In an embodiment, a quick disconnect feature (e.g., a latch, a lever, etc.) can be used to interchange the rotating assembly 108. In addition, the rotating elements 110 can be interchanged with each other instead of replacing the rotating assembly 108.

[0106] Fig.18A and Fig.18B An end view of a rotating assembly 108 is shown according to an example of the present disclosure. Fig.18A A first end 1702 of the rotating assembly 108 is shown, and Fig.18BThe second end 1704 of the rotating assembly 108 is shown. The first frame 716 includes a first base 800, and the first column 712 extends from the first base 800, wherein the first column 712 extends in a direction toward the second frame 718 (or the second base 1700). Similarly, the second frame 718 includes a second base 1700, and the second column 714 extends from the second base, wherein the second column 714 extends in a direction toward the first frame 716 (or the first base 800). The first column 712 and / or the second column 714 can be hollow to allow a fastener to be inserted into the second column 714, thereby coupling the second column 714 to the first column 712. In an embodiment, the fastener can be inserted into the first opening 1800 of the first base 800 to insert the fastener into the first column 712 to couple to the second column 714. Alternatively, the second column 714 can include a second opening 1802 for inserting the fastener into the first column 712. Fasteners may couple the first frame 716 and the second frame 718 together.

[0107] The first base 800 forms a first race 1706 for being disposed on the collar 1104, and the second base 1700 forms a second race 1708 for receiving the bearing 708. As shown, the size (e.g., cross-sectional size) of the first race 1706 can be larger than the second race 1708. In some embodiments, the first race 1706 receives the bearing. However, other sizes of the first race 1706 and / or the second race 1708 may include sizes different from those described.

[0108] Fig.19 An example according to the present disclosure is shown along Fig.18A 19. A cross-sectional view of the rotating assembly 108 taken along line CC of FIG. 19. For example, the first frame 716 and the second frame 718 may be coupled together to form an axis 710 around which the rotating element 110 is disposed. As described above, the axis 710 may be formed via a first column 712 of the first frame 716 and a second column 714 of the second frame 718. In an embodiment, the first column 712 includes a first channel 1900, and the second column 714 includes a second channel 1902. A fastener may be disposed within the first channel 1900 and / or the second channel 1902 to couple the first frame 716 and the second frame 718. For example, in an embodiment, the fastener may be placed in the first channel 1900 and fastened to the second column 714. Alternatively, the fastener may be placed in the second channel 1902 and fastened to the first column 712. The cross-sectional thickness, size, etc. of the first channel 1900 and the second channel 1902 may be different or similar. However, although described as being coupled together via fasteners, the first frame 716 and the second frame 718 may be coupled via a press fit, a snap fit, a force fit, or the like.

[0109] In an embodiment, the rotating element 110 can be disposed around a bushing on the first frame 716 and / or the second frame 718. For example, a first end of the first rotating element 110(1) and / or a first end of the second rotating element 110(2) can be disposed at or on the first frame 716 (e.g., the first base 800) around a first bushing 1904. A second end of the first rotating element 110(1) and / or a second end of the second rotating element 110(2) can be disposed at or on the second frame 718 (e.g., the second base 1700) around a second bushing 1906. In an embodiment, the first bushing 1904 and / or the second bushing 1906 can secure the first rotating element 110(1) and the second rotating element 110(2) to the first frame 716 and the second frame 718. Additionally or alternatively, the first bushing 1904 and / or the second bushing 1906 may provide rotational motion to the first rotating element 110 ( 1 ) and the second rotating element 110 ( 2 ) (eg, such that the first rotating element 110 ( 1 ) and the second rotating element 110 ( 2 ) may rotate around the axis 710 ).

[0110] As further shown, rotating assembly 108 includes a central cavity 1908 for disposing around housing 904. Housing 904 can extend at least partially into central cavity 1908 to be disposed between rotating elements 110 and allow second end 1002 of first assembly 900 to couple to rod 706 of second assembly 902.

[0111] Fig. 20 A side view of a rotating assembly 108 according to an example of the present disclosure is shown with the rotating element 110 removed. The first frame 716 and the second frame 718 are shown coupled together to form the shaft 710. As shown, the first column 712 can extend from the first base 800, and the second column 714 can extend from the second base 1700. When coupled together, the first column 712 and the second column 714 can be aligned to form the shaft 710. In an embodiment, as described above, fasteners can be provided in the first channel 1900 and / or the second channel 1902 to couple the first frame 716 and the second frame 718 together. In an embodiment, the rotating element 110 can be placed around the first column 712 and / or the second column 714 before coupling the first frame 716 and the second frame 718 together.

[0112] First bushing 1904 is shown disposed about first post 712 proximate first base 800, while second bushing 1906 is shown disposed about second post 714 proximate second base 1700. First bushing 1904 and second bushing 1906 may have a cross-sectional dimension greater than that of shaft 710 (or first post 712 and second post 714).

[0113] The first base 800 may include one or more first fins 2000, and the second base 1700 may include one or more second fins 2002. As shown, the first fin 2000 may extend from the first base 800 in a direction toward the second base 1700, and the second fin 2002 may extend from the second base 1700 in a direction toward the first base 800. The first fin 2000 and / or the second fin 2002 may include a triangle, various curves and / or arcs, a cone, etc. As will be explained herein, the first fin 2000 and the second fin 2002 may fill the gap between adjacent rotating elements 110 near the first base 800 and the second base 1700. For example, this may prevent a user's part (e.g., a finger) or clothing from being entangled, squeezed, or drawn in during operation of the device 100. As shown, the first fin 2000 may be disposed between adjacent first posts 712, and the second fin 2002 may be disposed between adjacent second posts 714.

[0114] Figure 21A-Figure 21D Various views of the first frame 716 according to an example of the present disclosure are shown. The first frame 716 includes a first base 800 disposed at a first end 2100 of the first frame 716. The first frame 716 may include a second end 2102 spaced apart (e.g., in the X direction) from the first end 2100. The first column 712 may extend from the first base 800 to the second end 2102. In an embodiment, the first column 712 includes a proximal end 2104 extending from or disposed at the first base 800 and a distal end 2106 disposed at the second end 2102. The length of the first column 712 may extend between the proximal end 2104 and the distal end 2106 (e.g., in the X direction).

[0115] In an embodiment, the first post 712 can include different cross-sectional dimensions. For example, at the proximal end 2104, the first post 712 can include a first cross-sectional dimension that is greater than a second cross-sectional dimension at the distal end 2106. The first cross-sectional dimension can receive the first bushing 1904 so that the first bushing 1904 can extend or be disposed on the first cross-sectional dimension of the first post 712.

[0116] As shown, the first frame 716 may include eight first posts 712. However, in embodiments, the first frame 716 may include more or less than eight first posts 712. In embodiments, the first posts 712 may be equally spaced around the first base 800. As will be explained herein, the second base 1700 may include a corresponding number of second posts 714 to abut, couple, and align with the first posts 712. The first post 712 may also include a first channel 1900, which may be open at the proximal end 2104 and / or the distal end 2106. For example, a fastener may be inserted into the proximal end 2104 via the first channel 1900 (or at the first end 2100 of the first frame 716) to couple to the second post 714. The first channel 1900 may also be open at the distal end 2106 of the first post 712 to receive a fastener (e.g., from a fastener disposed in the second channel 1902), or so that a fastener may be disposed from the first post 712 to the second post 714.

[0117] The first frame 716 may also include a flange 2108 extending from the first base 800 in a direction toward the second end 2102. In an embodiment, the fourth gear 810 may be disposed within the flange 2108. The first fin 2000 is shown extending from the first base 800 in a direction toward the second end 2102. The first fin 2000 may be disposed between the fourth gear 810 (or flange 2108) and the radial direction of the periphery of the first base 800. The first fin 2000 may extend from the first base 800 to various lengths, and the first fin 2000 may include a certain width (e.g., in a direction between adjacent first columns 712). As shown, the first frame 716 may include eight first fins 2000 disposed between adjacent first columns 712.

[0118] Figure 22A-22D Various views of a second frame 718 according to an example of the present disclosure are shown. The second frame 718 includes a second base 1700 disposed at a first end 2200 of the second frame 718. The second frame 718 may include a second end 2202 spaced apart (e.g., in the X direction) from the first end 2200. The second column 714 may extend from the second base 1700 to the second end 2202. In an embodiment, the second column 714 includes a proximal end 2204 extending from or disposed at the second base 1700 and a distal end 2206 disposed at the second end 2202. The length of the second column 714 may extend between the proximal end 2204 and the distal end 2206 (e.g., in the X direction).

[0119] In an embodiment, the second post 714 can include different cross-sectional dimensions. For example, at the proximal end 2204, the second post 714 can include a first cross-sectional dimension that is greater than a second cross-sectional dimension at the distal end 2206. The first cross-sectional dimension can receive the second bushing 1906 so that the second bushing 1906 can extend or be disposed on the first cross-sectional dimension of the second post 714. The second cross-sectional dimension at the distal end 2206 can be less than the first cross-sectional dimension of the first post 712 at the distal end 2106 so that the distal end 2206 of the second post 714 can be inserted into the distal end 2106 of the first post 712. This engagement (i.e., the distal end 2206 is at least partially located within the distal end 2106) can help secure and align the first post 712 and the second post 714.

[0120] The second post 714 can also include a third cross-sectional dimension between the proximal end 2104 and the distal end 2106. The third cross-sectional dimension can be smaller than the first cross-sectional dimension of the second post 714 at the proximal end 2204, but can be larger than the second cross-sectional dimension of the second post 714 at the distal end 2206. In other words, the distal end 2206 of the second post 714 can be at least partially disposed within the distal end 2106 of the first post 712. For example, the distal end 2206 can include a protrusion disposed within a recess at the distal end 2106.

[0121] As shown, the second frame 718 may include eight second posts 714. However, in embodiments, the second frame 718 may include more or less than eight second posts 714. In embodiments, the second posts 714 may be equally spaced around the second base 1700. The second base 1700 may include a corresponding number of second posts 714 to abut, couple, and align with the first posts 712. The second posts 714 may also include a second channel 1902, which may be open at a proximal end 2204 and / or a distal end 2206. For example, a fastener may be inserted into the proximal end 2204 of the second channel 1902 (or the first end 2200 of the second frame 718) to couple to the first post 712. The second channel 1902 may also be open at the distal end 2206 of the second post 714 to receive a fastener (e.g., from a fastener disposed in the first channel 1900), or so that a fastener may be disposed from the second post 714 to the first post 712.

[0122] The second fin 2002 is shown extending from the second base 1700 in a direction toward the distal end 2206 of the second column 714. The second fin 2002 can be disposed between the second race 1708 and the radial direction of the periphery of the second base 1700. The second fin 2002 can extend from the second base 1700 to various lengths, and the second fin 2002 can include a certain width (e.g., in a direction between adjacent second columns 714). As shown, the second frame 718 can include eight second fins 2002 disposed between adjacent second columns 714.

[0123] Fig.23 A second fin 2002 disposed between adjacent rotating elements 110 according to an example of the present disclosure is shown. As shown, the second fin 2002 can extend from the second base 1700 to be disposed between the second end of the first rotating element 110 (1) and the second end of the second rotating element 110 (2). In an embodiment, for example, the second fin 2002 can include, for example, a first side 2300 (e.g., a surface, a face, an edge, etc.) facing (e.g., oriented toward) the second end of the first rotating element 110 (1) and a second side 2302 (e.g., a surface, a face, an edge, etc.) facing (e.g., oriented toward) the second end of the second rotating element 110 (2). In an embodiment, the first side 2300 and the second side 2302 include different shapes, contours, etc. For example, the first side 2300 can extend substantially flat from the second base 1700, while the second side 2302 can include a curve. The different shapes of the first side 2300 and the second side 2302 can complement the shapes, contours, and surfaces of the second end of the first rotating element 110(1) and the second end of the second rotating element 110(2), respectively. Considering the arrangement of the first rotating element 110(1) and the second rotating element 110(1) on the first frame 716 and the second frame 718, the adjacent first sides 2300 of the second fin 2002 can be oriented toward each other, and similarly, the adjacent second sides 2302 of the second fin 2002 can be oriented toward each other.

[0124] Although the discussion is about the second fin 2002 disposed between the second end 2102 of the first rotating element 110 (1) and the second end 2202 of the second rotating element 110 (2), the first fin 2000 may also be similarly disposed between the first end 2100 of the first rotating element 110 (1) and the first end 2200 of the second rotating element 110 (2).

[0125] Figure 24A-Figure 24D Various views of a first rotating element 110 ( 1 ) are shown according to examples of the present disclosure. Fig.24A shows a side view of the first rotating element 110 ( 1 ), Fig. 24B An end view of the first rotating element 110 ( 1 ) is shown, Fig.24C Shown along Fig.24A The first cross-sectional view of the first rotating element 110 (1) is taken along the line DD, and Fig.24D Shown along Fig. 24B A second cross-sectional view of the first rotating element 110 ( 1 ) taken along line EE.

[0126] The first rotating element 110(1) can include a first end 2400 and a second end 2402 spaced apart (e.g., in the X direction) from the first end 2400. The first rotating element 110(1) can include an outer surface 2404 and an inner surface 2406 formed within or by a channel 2408 extending through the first rotating element 110(1) between the first end 2400 and the second end 2402. As shown, the outer surface 2404 can undulate along the longitudinal direction of the first rotating element 110(1) between the first end 2400 and the second end 2402. For example, the first rotating element 110(1) can include a first thickness 2410 at certain locations along the length of the first rotating element 110(1) and a second thickness 2412 at certain locations along the length of the first rotating element 110(1). The first thickness 2410 may be disposed at the peaks of the outer surface 2404 (or the undulating surface), and the second thickness 2412 may be disposed at the valleys of the outer surface 2404 (or the undulating surface). The peaks may be disposed between adjacent valleys, and the valleys may be disposed between adjacent peaks.

[0127] In an embodiment, the peak of the outer surface 2404 corresponds to a first myofascial feature 2414 of the device 100 for providing myofascial relief. For example, the first myofascial feature 2414 may include a spherical, triangular, circular, etc. knob, protrusion, etc. for providing myofascial relief. The first myofascial feature 2414 may be disposed at the first thickness 2410 of the first rotating element 110(1). In an embodiment, the first rotating element 110(1) may include five first myofascial features 2414, however, more or less than five first myofascial features 2414 may be included.

[0128] In an embodiment, the first thickness 2410 is disposed at a first distance from the first end 2400, and the second thickness 2412 is disposed at a second distance from the first end 2400. The second distance may be greater than the first distance. In an embodiment, the first thickness 2410 is disposed at the first end 2400 and / or the second end 2402. Furthermore, in an embodiment, adjacent portions of the first rotating element 110(1) including the second thickness 2412 are spaced apart from each other by a third distance.

[0129] The first rotating element 110(1) can include one or more ribs 2416 extending from the inner surface 2406 within the channel 2408. In an embodiment, the ribs 2416 engage the shaft 710, such as the first post 712 and the second post 714. For example, when the first rotating element 110(1) is slid onto the first post 712, the ribs 2416 can engage the first post 712. The fourth distance can separate the ends of adjacent ribs of the ribs 2416, and the fourth distance can be less than the cross-sectional dimension of the channel 2408 without the ribs 2416. In doing so, the portion of the inner surface 2406 that does not include the ribs 2416 can not engage the shaft 710. Such a gap (e.g., between the inner surface 2406 and the shaft 710) can allow portions of the first rotating element 110(1) to flex, bend, or deform during use. Although the first rotating element 110(1) is shown as including four ribs 2416, the first rotating element 110(1) can include more or less than four ribs 2416. Additionally, while shown as being equidistantly disposed about the inner surface 2406, the ribs 2416 may be disposed on the inner surface 2406 differently than shown.

[0130] In an embodiment, the first rotating element 110(1) may include a first recess 2418 at the first end 2400 and a second recess 2420 at the second end 2402. The first recess 2418 and / or the second recess 2420 may be disposed around the first bushing 1904 and / or the second bushing 1906 of the first frame 716 and the second frame 718, respectively. In an embodiment, the cross-sectional dimensions of the channel 2408 at the region corresponding to the first recess 2418 and the second recess 2420 may be larger than the region of the channel 2408 including the rib 2416. As such, the rib 2416 may not be disposed within the first recess 2418 and the second recess 2420.

[0131] Although the first rotating element 110(1) is shown as a single continuous piece of material, other variations are contemplated. For example, the first rotating element 110(1) may include separate and distinct pieces of material disposed along the first and second posts 712, 714 or above the shaft 710. In such an embodiment, these distinct components may, for example, be slid onto the shaft 710 and rotate independently.

[0132] Figure 25A-Figure 25D Various views of the second rotating element 110 ( 2 ) are shown according to examples of the present disclosure. Fig.25A shows a side view of the second rotating element 110 (2), Fig.25B An end view of the second rotating element 110 (2) is shown, Fig.25C Shown along Fig.25A The first cross-sectional view of the second rotating element 110 (2) is taken along the line FF, and Fig.25D Shown along Fig.25B A second cross-sectional view of the second rotating element 110 ( 2 ) taken along line GG.

[0133] The second rotating element 110(2) can include a first end 2500 and a second end 2502 spaced apart (e.g., in the X direction) from the first end 2500. The second rotating element 110(2) can include an outer surface 2504 and an inner surface 2506 formed within or by a channel 2508 extending through the second rotating element 110(2) between the first end 2500 and the second end 2502. As shown, the outer surface 2504 can undulate along the longitudinal direction of the second rotating element 110(2) between the first end 2500 and the second end 2502. For example, the second rotating element 110(2) can include a first thickness 2510 at certain locations along the length of the second rotating element 110(1) and a second thickness 2512 at certain locations along the length of the second rotating element 110(2). The first thickness 2510 may be disposed at the peaks of the outer surface 2504 (or the undulating surface), and the second thickness 2512 may be disposed at the valleys of the outer surface 2504 (or the undulating surface). The peaks may be disposed between adjacent valleys, and the valleys may be disposed between adjacent peaks.

[0134] In an embodiment, the peak of the outer surface 2504 corresponds to a second myofascial feature 2514 of the device 100 for providing myofascial relief. For example, the second myofascial feature 2514 may include a spherical, triangular, circular, etc. knob, protrusion, etc. for providing myofascial relief. The second myofascial feature 2514 may be disposed at the first thickness 2510 of the second rotating element 110(2). In an embodiment, the second rotating element 110(2) may include four second myofascial features 2514, however, more or less than four second myofascial features 2514 may be included. In an embodiment, the second myofascial feature 2514 may be different from or similar to the first myofascial feature 2414.

[0135] In an embodiment, the first thickness 2510 is disposed at a first distance from the first end 2500, and the second thickness 2512 is disposed at a second distance from the first end 2500. The second distance may be greater than the first distance. In an embodiment, the first thickness 2510 is disposed at the first end 2500 and / or the second end 2502. Furthermore, in an embodiment, adjacent portions of the second rotating element 110(2) including the second thickness 2512 are spaced apart from each other by a third distance.

[0136] The second rotating element 110(2) can include one or more ribs 2516 extending from the inner surface 2506 within the channel 2508. In an embodiment, the ribs 2516 engage with the shaft 710, such as the first column 712 and the second column 714. For example, when the second rotating element 110(2) is slid onto the first column 712, the ribs 2516 can engage with the first column 712. The fourth distance can separate the ends of adjacent ribs of the ribs 2516, and the fourth distance can be less than the cross-sectional dimension of the channel 2508 without the ribs 2516. In doing so, the portion of the inner surface 2506 that does not include the ribs 2516 can not engage with the shaft 710. Such a gap (e.g., between the inner surface 2506 and the shaft 710) can allow a portion of the second rotating element 110(2) to flex, bend, or deform during use. Although the second rotating element 110(2) is shown as including four ribs 2516, the second rotating element 110(2) can include more or less than four ribs 2516. Additionally, while shown as being equidistantly disposed about the inner surface 2506, the ribs 2516 may be disposed on the inner surface 2506 differently than shown.

[0137] In an embodiment, the second rotating element 110(2) may include a first recess 2518 at the first end 2500 and a second recess 2520 at the second end 2502. The first recess 2518 and / or the second recess 2520 may be disposed around the first bushing 1904 and / or the second bushing 1906 of the first frame 716 and the second frame 718, respectively. In an embodiment, the cross-sectional dimensions of the channel 2508 at the region corresponding to the first recess 2518 and the second recess 2520 may be the same as the region of the channel 2508 including the rib 2516. In an embodiment, the rib 2516 may not be disposed in the first recess 2518 and the second recess 2520.

[0138] Although the second rotating element 110(2) is shown as a single continuous piece of material, other variations are contemplated. For example, the second rotating element 110(2) may include separate and distinct pieces of material disposed along the first and second posts 712, 714, or above the shaft 710. In such an embodiment, these distinct components may, for example, be slid onto the shaft 710 and rotate independently.

[0139] Figure 26A-26C A bracket 102 according to an example of the present disclosure is shown. Figure 1As described in , the stand 102 can be configured to receive the device 100. For example, a user can place the device 100 in the stand 102 for storage or use (e.g., rolling some part of their body on the rotating element 110). The stand 102 includes a first container 114 for receiving a portion of the first handle 104 and a second container 116 for receiving a portion of the second handle 106. A slot 118 is located between the first container 114 and the second container 116 to receive the rotating assembly 108. When the first handle 104 is placed in the first container 114, the second button 400 can be pressed (e.g., via engagement with the bottom surface of the first container 114) so ​​that the user can operate the device 100.

[0140] The bracket 102 also includes a third container 2600 and a fourth container 2602 to receive at least a portion of the first collar 906 and the second collar 908, respectively. The third container 2600 can be disposed between the first container 114 and the groove 118, and the fourth container 2602 can be disposed between the second container 116 and the groove 118. The engagement between the first container 114 and the first handle 104, the second container 116 and the second handle 106, the third container 2600 and the first collar 906, and the fourth container 2602 and the second collar 908 can place, position and / or fix the device 100 in the bracket 102. In addition, the engagement between the device 100 and the bracket 102 can prevent the device 100 from rotating during use except for the rotating assembly 108. As shown, the first container 114, the second container 116, the third container 2600 and / or the fourth container 2602 can be semicircular.

[0141] Fig.27A and Fig.27B 1 shows exemplary components of an apparatus 100 according to an example of the present disclosure. More specifically, Fig.27A and Fig.27B The second assembly 902 is shown coupled to the first assembly 900. Initially, the components (e.g., the battery 700, the motor 702, etc.) can be installed within the first housing 506 and the second housing 508 of the first assembly 900. The rotating assembly 108 can then be assembled by installing the rotating element 110 on the first column 712 and then placing the second column 714 at least partially through the rotating element 110. The first frame 716 and the second frame 718 can be secured together by fasteners disposed in the first channel 1900 and the second channel 1902, thereby coupling the first column 712 and the second column 714 together. After sliding the rotating assembly 108 onto the housing 904, Fig.27A1, the fourth housing 512 can be coupled to the rod 706. For example, the rod 706 can be disposed through the channel 1206 in the fourth housing 512 and then coupled to the fourth housing 512 via a fastener disposed through the first passage 1504 in the rod 706. Once coupled, the second base 1700 can be at least partially disposed within the second flange 1404.

[0142] exist Fig.27A At "2" in FIG. 1 , the third housing 510 may be moved toward the second base 1700 so as to be disposed vertically above the fourth housing 512 (eg, in the X direction). Fig.27B At "3" in FIG. 1 , the third housing 510 may move toward the fourth housing 512 (e.g., in the Y direction). The portion of the third housing 510 corresponding to the second flange 1404 may be at least partially disposed on the second base 1700. Fig.27B At "4" in the figure, the third housing 510 and the fourth housing 512 can be coupled together using fasteners. For example, the fasteners can be set to / through the third housing 510 and the fourth housing 512 at a position within the second collar 908. Wherein, the second cover 602 can be placed around the second collar 908, for example, to hide the fasteners.

[0143] Fig.28 An alternative device 2800 is shown according to an example of the present disclosure. In an embodiment, device 2800 may be similar to device 100. For example, device 2800 may include first handle 104 and second handle 106. However, device 2800 may include a rotational assembly 2802 that is different than rotational assembly 108 of device 100.

[0144] More specifically, as described above with respect to the device 100, the rotating assembly 108 may include a first frame 716 and a second frame 718 having a first column 712 and a second column 714, respectively, wherein the first column 712 and the second column 714 form an axis 710, and the rotating element 110 is disposed around the axis 710. In contrast, the rotating assembly 2802 may include a first frame 2804 and a second frame 2806 and an axis 2808 extending between the first frame 2804 and the second frame 2806. However, the axis 2808 may not extend from the base of the first frame 2804 or the second frame 2806 (e.g., be integral therewith). Instead, the axis 2808 may be a separate component and, in an embodiment, include a first end coupled to the first frame 2804 and a second end coupled to the second frame 2806. For example, a fastener may at least partially pass through the first frame 2804 and the second frame 2806 and enter the axis 2808. The rotating element 110 is configured to be disposed around the axis 2808. The rotating element 110 can be disposed around the shaft 2808 before the shaft 2808 is coupled to the first frame 2804 and / or the second frame 2806. Additionally, in some cases, the bushing 2810 can be at least partially disposed on or around the first frame 2804 and / or the second frame 2806, and the rotating element 110 can be disposed around the bushing 2810.

[0145] Fig.29 A rotating assembly 2802 is shown according to an example of the present disclosure. The first frame 2804 may include or define a passage 2900 into which a fastener is disposed to couple to an end of a shaft 2808. Fig.29 In the view not shown in FIG. 2 , the second frame 2806 may similarly include a passage in which a fastener is disposed to couple to the opposite end of the shaft 2808. As described above, the rotating element 110 may be disposed around the shaft 2808 and / or the bushing 2810 prior to coupling the first frame 2804 and the second frame 2806 to the fasteners of the shaft 2808. The first frame 2804 may also include a first fin 2902, and the second frame 2806 may include a second fin 2904.

[0146] The first frame 2804 can define a first seat ring 2906, in which a bearing is arranged to rotationally couple the rotating assembly 2802 to the first handle 104 or around the first handle 104, and the second frame 2806 can define a second seat ring 2908, in which a bearing is arranged to rotationally couple the rotating assembly 2802 to the second handle 106 or around the second handle 106.

[0147] Fig.30A first frame 2804 according to an example of the present disclosure is shown. In an embodiment, the first frame 2804 may include a first base 3000 from which the first fin 2902 extends, or the first base defines the first fin 2902. In addition, the first frame 2804 may include a first race 2906 for receiving a bearing. The first frame 2804 or the first base 3000 includes a first container 3002 (e.g., a pocket, a groove, a hole, etc.), and the shaft 2808 is at least partially disposed in the first container 3002. For example, one end of the shaft 2808 can be placed into the first container 3002. In an embodiment, the first container 3002 is disposed within a first column 3004 extending from the first base 3000. The bushing 2810 can be disposed around the first column 3004. In addition, the passage 2900 can extend into the first container 3002 to couple to the shaft 2808.

[0148] Fig.31 A second frame 2806 according to an example of the present disclosure is shown. In an embodiment, the second frame 2806 may include a second base 3100 from which the second fin 2904 extends, or the second base 3100 defines the second fin 2904. In addition, the second frame 2806 may include a second race 2908 for receiving a bearing. The second frame 2806 or the second base 3100 includes a second container 3102 (e.g., a recess, a groove, a hole, etc.), and the shaft 2808 is at least partially disposed in the second container. For example, the end of the shaft 2808 can be placed into the second container 3102. In an embodiment, the second container 3102 is disposed in a second column 3104 extending from the second base 3100. The bushing 2810 can be disposed around the second column 3104.

[0149] Fig.32 A shaft 2808 according to an example of the present disclosure is shown. The shaft 2808 may include a body 3200 extending between a first end 3202 and a second end 3204 (e.g., spaced apart from the first end 3202 in the X direction). The length of the shaft 2808 extends between the first end 3202 and the second end 3204. The first end 3202 includes a first notch 3206 (e.g., a dent, a keyway, etc.) disposed within the first container 3002. The first end 3202 also includes a first opening 3210 that aligns with the passage 2900 in the first frame 2804 to receive a fastener and couple the shaft 2808 to the first frame 2804. The second end 3204 includes a second notch 3208 (e.g., a dent, a keyway, etc.) disposed within the second container 3102. The second end 3204 also includes a second opening that aligns with the passage to receive a fastener and so as to couple the shaft 2808 to the second frame 2806.

[0150] Fig.33Selected components of apparatus 100 are shown according to an example of the present disclosure. Although described as components of apparatus 100, apparatus 2800 may include similar or different components.

[0151] The device 100 is shown as including a processor 3300 and a memory 3302, wherein the processor 3300 can cause the device 100 to perform various functions and operations associated with providing or treating muscle pain, myofascial pain, trigger points, etc., and the memory 3302 can store instructions that can be executed by the processor 3300 to perform the operations described herein.

[0152] The device 100 can operate according to certain settings 3304. In an embodiment, the setting 3304 indicates the speed of the motor 702 used to rotate the rotating component 108. For example, the setting 3304 can indicate the revolutions per minute (RPM) at which the motor 702 operates. In an embodiment, the motor 702 can have different RPMs according to the speed desired by the user. In an embodiment, the motor 702 can operate at five different speeds, however, the motor 702 can have the ability to operate at less than or greater than five speeds. In an embodiment, the speed of the motor 702 can be received via one or more buttons 3306 of the device 100. For example, the user can provide input to the button 3306 (e.g., the first button 112) to indicate the desired speed of the motor 702. The user can provide the setting 3304 through the button 3306 or other input components (e.g., a lever, a dial, etc.).

[0153] The buttons 3306 may also include a second button 400, which in an embodiment corresponds to a safety button. For example, in order to adjust or set the speed of the motor 702, the second button 400 may be pressed first. In other words, pressing the first button 112 without pressing the second button 400 may limit the operation of the device 100. However, pressing the second button 400 and continuing to press the second button 400 while pressing the first button 112 may allow the operation of the device 100. After pressing the first button 112 (while pressing the second button 400), the second button 400 may be released so as to operate the device 100 without continuing to press the second button 400. However, in an embodiment, the second button 400 may be continuously pressed to operate the device 100. When placed in the bracket 102, the second button 400 may be pressed via the bracket 102 (e.g., in the Y direction).

[0154] In an embodiment, the speed of the motor 702 can be set by pressing and holding for different time periods. For example, pressing and holding the first button 112 for a first time period (e.g., one second) can cause the motor 702 to operate at a first speed, pressing and holding the button for a second time period (e.g., two seconds) can cause the motor 702 to operate at a second speed different from the first speed, and so on. In addition, the first button 112 can be pressed a certain number of times to change the speed, rather than providing different inputs at different time periods. For example, pressing the first button 112 once can cause the motor 702 to operate at a first speed, pressing the first button 112 twice (e.g., consecutively) can cause the motor 702 to operate at a second speed, and so on.

[0155] The device 100 may include an illumination element 3308 that may output an indication of the settings 3304 of the device 100, an operating state / condition of the device 100, etc. For example, the illumination element 3308 may output light to indicate whether the device 100 is on. The illumination element 3308 may output light based on a determined speed of the motor 702. For example, the illumination element 3308 may output light to indicate the speed of the motor 702. This may provide visual feedback to the user regarding the selected speed of the motor 702. In an embodiment, the illumination element 3308 may output light through the light guide 1204, wherein each portion (e.g., segment, fork, etc.) of the light guide 1204 may be individually illuminated to indicate the speed of the motor 702.

[0156] Settings 3304 may include other operating characteristics of device 100 in addition to the speed of motor 702. For example, settings 3304 may be associated with a vibration motor imparting vibrations to device 100, heat generated by a heater of device 100, cycle times for motor 702 to turn on / off, changing speeds, changing directions of rotation, etc. As such, it should be appreciated that a user or device 100 may operate according to settings 3304 to provide or treat muscle pain, myofascial pain, trigger points, etc.

[0157] Although the device 100 is shown as including certain components, the device 100 may include additional or alternative components other than those described. For example, the device 100 may include a speaker for outputting sounds (e.g., sounds associated with the settings 3304, sounds related to the user's training / therapy session, etc.), a microphone for capturing sounds (e.g., user sentences, voice commands, etc.), a vibration motor, a heater for generating heat, a network interface for communicating with one or more devices (e.g., a mobile phone), etc.

[0158] The device 100 also includes a battery 700 for powering the device 100 and the components therein. For example, the battery 700 can be coupled to a motor 702. In an embodiment, the motor 702 can represent a brushless motor. The battery 700 can also be recharged (e.g., via a port) and / or replaced.

[0159] The device 100 may also include a sensor 3310 that generates sensor data 3312. The sensor 3310 may include a temperature sensor, an ammeter sensor, a voltage sensor, etc. In an embodiment, the sensor 3310 may measure the current on the motor 702, wherein the sensor data 3312 represents the current supplied to the motor 702. The sensor data 3312 can be used to dynamically adjust the settings 3304 of the device 100, for example, based on the resistance to the motor 702. If the user changes the amount of force that the device 100 (e.g., the rotating assembly 108) is pressed against their body (e.g., legs, arms, etc.), the speed of the motor 702 and the speed of the rotating assembly 108 can be reduced. The sensor 3310 can measure the suction on the motor 702, and if the suction is greater than a certain threshold for a certain period of time, the motor 702 can dynamically increase the speed to account for the increased resistance.

[0160] For illustration, assume that the user selects the fourth setting (e.g., speed) of the motor 702. Under this setting, the motor 702 can rotate the rotating assembly 108 at a certain speed. During use, if the user presses the rotating assembly 108 against their body with a certain amount of force, the rotating assembly 108 can rotate at a slower speed than desired (e.g., less than). That is, the force can provide resistance to the motor 702, and as a result, the rotating assembly 108 may not rotate at the desired speed. If the resistance on the motor 702 is greater than the threshold value within the threshold time period, the device 100 can supply an increased current to the motor 702 to rotate it at the desired speed. In doing so, the user can apply the device 100 to their body with a given force without sacrificing the speed at which the rotating assembly 108 rotates. After removing the device 100, the resistance provided to the motor 702 is less, and therefore, the motor 702 can rotate the rotating assembly 108 at a higher speed. However, if the current on the motor 702 is less than the threshold value within the threshold time period, the device 100 can reduce the current supplied to the motor 702 to reduce its speed.

[0161] As used herein, a processor, such as processor 3300, may include multiple processors and / or processors with multiple cores. In addition, the processor may include one or more cores of different types. For example, the processor may include an application processor unit, a graphics processing unit, etc. In one embodiment, the processor may include a microcontroller and / or a microprocessor. The processor may include a graphics processing unit (GPU), a microprocessor, a digital signal processor, or other processing units or components known in the art. Alternatively or additionally, the functions described herein may be performed at least in part by one or more hardware logic components. For example, but not limited to, exemplary types of hardware logic components that may be used include field programmable gate arrays (FPGAs), application specific integrated circuits (ASICs), application specific standard products (ASSPs), systems on chips (SOCs), complex programmable logic devices (CPLDs), etc. In addition, each processor may have its own local memory, which may also store program components, program data, and / or one or more operating systems.

[0162] Memory, such as memory 3302, can include volatile and non-volatile memory, removable and non-removable media implemented in any method or technology for storing information, such as computer-readable instructions, data structures, program components, or other data. Such memory can include, but is not limited to, RAM, ROM, EEPROM, flash memory or other storage technology, CD-ROM, digital versatile disk (DVD) or other optical storage, cassettes, magnetic tape, disk storage or other magnetic storage devices, RAID storage systems, or any other medium that can be used to store the required information and can be accessed by the computing device. The memory can be implemented as a computer-readable storage medium ("CRSM"), which can be any available physical medium accessible to the processor to execute the instructions stored on the memory. In a basic implementation, the CRSM can include random access memory ("RAM") and flash memory. In other implementations, the CRSM can include, but is not limited to, read-only memory ("ROM"), electrically erasable programmable read-only memory ("EEPROM"), or any other tangible medium that can be used to store the required information and can be accessed by the processor. Memory 3302 is an example of a non-transitory computer-readable medium. Memory 3302 may store an operating system and one or more software applications, instructions, programs, and / or data to implement the methods and functionality attributed to the various systems described herein.

[0163] Fig.34An exemplary program 3400 for at least partially controlling the operation of device 100 and / or device 2800 according to an example of the present disclosure is shown. The program 3400 described herein is shown as a collection of blocks in a logical flow chart, which represents a sequence of operations, some or all of which can be implemented in hardware, software, or a combination thereof. In the context of software, these blocks may represent computer-executable instructions stored on one or more computer-readable media, which, when executed by one or more processors, program the processors to perform the operations. Generally, computer-executable instructions include routines, programs, objects, components, data structures, etc. that perform specific functions or implement specific data types. Unless otherwise specified, the order in which the blocks are described should not be construed as limiting. Any number of the described blocks may be combined in any order and / or in parallel to implement the program or an alternative program, and all blocks need not be executed. For purposes of discussion, the program 3400 is described with reference to the environment, architecture, devices, and systems described in the examples herein, such as with reference to Figure 1-Figure 33 Those described, although the process 3400 can be implemented in a variety of other environments, architectures, devices, and systems.

[0164] At 3402, the process 3400 may include receiving data associated with a first setting of the device. For example, the processor 3300 may detect input to one or more buttons of the device 100 to at least partially control the device 100. In an embodiment, the setting of the device 100 is associated with the speed of the motor 702 that rotates the rotating assembly 108. Therefore, the setting of the device 100 may correspond to the speed at which the rotating assembly 108 rotates via the motor 702. For example, the user may have the ability to control the setting so that the rotating assembly 108 rotates at different speeds.

[0165] At 3404, the process 3400 may include causing the device to operate according to a first setting. For example, after receiving the first data or as part of receiving the first data, the processor 3300 may energize the motor 702 or rotate the rotating assembly 108 according to the desired setting. In an embodiment, causing the device 100 to operate according to the desired setting may include supplying a first amount of current to the motor 702 to rotate the rotating assembly 108 at a selected speed.

[0166] At 3406, the routine 3400 can include determining the current draw on the motor of the device. For example, the processor 3300 can determine the current draw on the motor 702 when operating at the setting. The current draw can correspond to the amount of current supplied to the motor 702 to rotate the rotating assembly 108 at the selected setting (e.g., speed). For example, a sensor can measure the current draw.

[0167] At 3408, the program 3400 may include determining whether the current consumption is greater than a first threshold. For example, using the current consumption on the motor 702 from 3406, the program 3400 may determine whether the current consumption is greater than a first threshold. In an embodiment, the first threshold may be based at least in part on the current supplied to the motor 702 to operate the device 100 at a desired setting. That is, in order to rotate the rotating component 108 at a desired speed, a certain current (e.g., 3 amps) may be supplied to the motor 702. The first threshold may be determined based on the supplied current so that the rotating component 108 rotates at a desired speed. Therefore, the first threshold may be 4 amps. In contrast, if a different speed is selected, such as a faster speed, the current for rotating the rotating component 108 at the desired speed may be 5 amps. For this setting, the threshold may be 6 amps. In an embodiment, the current consumption may be the average current within a specific time window (e.g., five seconds). Therefore, the first threshold for comparing the current consumption may be based at least in part on the baseline current for rotating the rotating component 108 at a selected speed.

[0168] If at 3408, the routine 3400 determines that the current consumption is not greater than the threshold, the routine 3400 can follow the "no" route and loop to 3404 to continue operating the device 100 at the first setting. In contrast, if at 3408, the routine 3400 determines that the current consumption is greater than the first threshold, the routine 3400 can follow the "yes" route and continue to 3410.

[0169] At 3410, the routine 3400 may include determining whether the current consumption is greater than a second threshold value. In an embodiment, the second threshold value may be associated with a threshold time period. For example, the routine 340 may determine whether the current consumption is greater than a threshold current consumption (e.g., a first threshold value) within a threshold time period (e.g., a second threshold value). In an embodiment, the threshold time period may be one second, two seconds, five seconds, etc. Determining whether the current consumption is greater than the threshold current consumption within the threshold time period may avoid inadvertently changing the first setting of the device 100. If at 3410, the routine 3400 determines that the current consumption is not greater than the first threshold value of the second threshold value (e.g., the threshold time period), the routine 3400 may follow the "no" route and loop to 3404 to continue operating the device 100 under the first setting. In contrast, if the routine 3400 determines that the current consumption is greater than the first threshold value of the second threshold value, the routine 3400 may follow the "yes" route and continue to 3412.

[0170] At 3412, the process 3400 may include causing the device to operate according to a second setting. For example, although the first setting is selected to cause the rotating assembly 108 to rotate at a particular speed, the user may apply sufficient force to the device 100 (and therefore to the rotating assembly 108) to cause the rotatable body 108 to rotate at a speed less than the selected speed (e.g., to take into account the resistance transmitted to the motor 702). In this case, the device 100 may cause an increased current to be supplied to the motor 702 so that the rotating assembly 108 rotates at the selected speed under the resistance of the user pressing / pressing the rotating assembly 108 into their body. Thus, this real-time adjustment accommodates the use of the user to operate the device 100 at the selected speed.

[0171] After the device 100 is removed, less resistance is provided to the motor 702, and therefore, the motor 702 can rotate the rotating assembly 108 at a higher speed than required. Here, the current consumption on the motor 702 can be determined, and if the current consumption on the motor 702 is less than a threshold value for a threshold period of time, the device 100 can reduce the current supplied to the motor 702 to reduce its speed.
