[0011] In some embodiments, the hula hoop further comprises a weight element connected to the slide by a tether, and wherein the weight element comprises a shell filled with at least one of water, sand and metal particles (eg, iron, copper or alloy).

[0012] In some embodiments, the inner rail has a slot at the first end, and the engaging portion of the outer rail is configured to be inserted into the slot, so that the connection between the inner rail and the outer rail along a direction substantially perpendicular to the positioning column is stable.

[0013] In some embodiments, the pressing assembly is switchable between a first position and a second position, wherein the elastic element of the pressing assembly is deformed by force to move away from the pressing body of the pressing assembly; in the second position, the elastic element of the pressing assembly is not subjected to force and remains basically stationary relative to the external rail and / or the internal rail.

[0014] In certain embodiments, the inner track has a limit post configured to limit the movement of the user-operated pressing body.

[0015] In some embodiments, the pressing assembly further includes a positioning body defining a positioning channel, and the positioning post of the outer rail extends through the positioning channel and is inserted into the positioning hole of the inner rail.

[0016] In some embodiments, the material of the pulley is selected from at least one of nylon, polyoxymethylene, ABS and polyurethane, which is conducive to reducing noise.

[0017] The present application provides a hula hoop that is easy to assemble and disassemble.

[0018] The present application also provides a hula hoop with a light emitting device (LED).

[0019] The present application also provides a hula hoop with a weight element filled with water, and the amount of water is easy to adjust and convenient to replenish.

[0020] The present application also provides a hula hoop, which includes: a track assembly, which includes a plurality of track units interconnected end to end, the track units including: an outer track having a receiving channel located at a first end and a protrusion located at a second end opposite to the first end; a pressing assembly; an inner track, which together with the outer track defines an annular path; and a slide seat, the slide seat is provided with a pulley, and the pulley is configured to slide on the annular path, wherein the protrusion of the outer track may include side protrusions and middle protrusions located between the side protrusions, and the side protrusions are configured to be inserted into the side channels of the receiving channel, so that after assembly is completed, the distance between the end face of the side protrusion of the outer track and the end face of the adjacent outer track that defines the side channel is in the range of 0.5mm-10mm.

[0021] The gap between the outer tracks of the track unit of the hula hoop of the present application is very small, so that when the pulley of the slide seat slides on the annular path defined by the inner track and the outer track, it will not pass through a long road with a gap (which will cause the movement of the slide seat to be blocked and cause a lot of noise). This design greatly reduces the generation of noise, and combined with the pulley of the material mentioned above, it can even achieve silence. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] Figure 1 A hula hoop according to an embodiment of the present application is shown. The hula hoop comprises a track assembly 10 and a slide seat 20 that can slide on the track assembly 10. The track assembly 10 can be used to be worn on the waist of a user, and the slide seat 20 connected with a weight can slide circumferentially as the user's waist twists.

[0033] Figure 2 A perspective view of a slide 20 according to an embodiment is shown in detail. The slide 20 may include two halves defined by a dividing line or plane 26, each half including a base portion 21 and an extension portion 22 extending therefrom. The two halves after being assembled together define an inner cavity, in which various electronic components, such as sensors and controllers, etc., may be arranged, which will be described in detail later.

[0034] Each base portion 21 has a substantially L-shaped cross section, and the base portion 21 has one or more pulley rods 212, and each pulley rod 212 is provided with a pulley (not shown) that can rotate around the pulley rod 212. The material of the pulley can be selected from any one of nylon, polyoxymethylene, ABS and polyurethane or a combination thereof. Preferably, the pulley can be made of wear-resistant TPU GU80. The above materials used to make the pulley are conducive to generating less sound.

[0035] In some embodiments, each extension 22 has a first opening, and the first openings of the two extensions 22 can cooperate so that the assembled slide 20 defines a cavity for accommodating a light emitting device (e.g., an LED). In some embodiments, two cavities are arranged on the preferably curved side plane of the slide 20. The light emitting device can be installed in the cavity of the slide 20, which can be enclosed by a plastic shell or the like.

[0036] Figure 2 Also shown is a tether opening 224 of the carriage 20 for introducing a tether to be connected, which tether can be connected to a counterweight. In some embodiments, the tether opening 224 is defined by only one of the two halves (i.e., is formed in only a single half). In some embodiments, the tether opening 224 is defined by both halves.

[0037] Figure 3 and Figure 4 The front view and the rear view of the slide 20 are shown respectively. The slide 20 may be provided with a display panel or a control panel 31 on the front, on which at least one button selected from, for example, a counting button, a pause button and a reset button may be integrated, and the exercise time and the number of revolutions may also be displayed. Accordingly, a charging port 41, such as a USB port, may be provided on the opposite side (e.g., the back side) of the slide 20. The slide 20 also includes a plurality of holes 43, 45 for mounting bolts.

[0038] A sensor, such as a speed sensor, especially an angular velocity sensor, may be provided in the slide 20 to detect the sliding speed of the slide on the track unit. A controller may also be provided in the slide 20, in which a program may be loaded, and the program is executed to control, for example, the lighting of an LED according to the value detected by the sensor, for example, to make different LEDs emit different colors of light in a flashing or long-lighting manner according to speeds within different ranges.

[0039] Figure 5 A track assembly including a plurality of track units 50 according to an embodiment is shown, wherein two adjacent track units 50 are interconnected end to end, preferably by means of plug-in and snap-fit ​​connection.

[0040] Figure 6 shows an exploded view of a track unit according to an embodiment, and Figure 7 1 shows a cross-sectional view of an assembled track unit according to an embodiment. Figure 6-7 As shown, each track unit (e.g. Figure 5 The track unit 50 shown in FIG. 1 includes an outer track 52 , an inner track 56 and a pressing assembly 54 .

[0041] The outer rail 52 has a receiving channel 522 at a first end and a protruding portion 526 at a second end opposite to the first end. The protruding portion 526 of the outer rail 52 can be inserted into the receiving channel 522 of the adjacent outer rail 52. Figure 8 The receiving channel 522 is more clearly shown, and includes side channels 5222, 5226 that at least partially define a track (i.e., a track on which the pulleys of the slide travel) and a middle channel 5224 located between the side channels 5222, 5226. The protrusion 526 of the outer rail 52 similarly includes three protrusions to correspond to the channels 5222, 5226, 5224. The connected outer rail and the adjacent outer rail are locked by the pressing assembly 54, which will be described in detail later.

[0042] The inner rail 56 has a positioning hole 562, and the positioning post 528 of the outer rail 52 can be inserted into the positioning hole 562 to achieve the fixation between the inner rail 56 and the outer rail 52 (preferably as shown in FIG. Figure 7 ). The inner track 56 also has a male fitting 564 at a first end and a female fitting 566 at a second end opposite the first end, so that the male fitting 564 of the inner track 56 can be connected with the female fitting 566 of the adjacent inner track. For example, the male fitting 564 and the female fitting 566 have complementary profiles.

[0043] The inner rail 56 may also have a slot 567 at the first end, and the snap-in portion 527 of the outer rail 52 may be inserted into the slot 567, so that the connection between the inner rail 56 and the outer rail 52 in a substantially vertical direction (i.e., a direction substantially perpendicular to the positioning column 528) is stable.

[0044] It can be seen that the connection points between adjacent track units are located at the ends of the track units, while the connection points between the inner and outer rails of the track units are located between the ends of the track units.

[0045] The pressing assembly 54 has a pressing body 541, which can be embedded in a hole on the outer surface of the outer rail 52 and extend beyond the outer surface of the outer rail 52 after assembly, so that a user can easily press the pressing body 541 of the pressing assembly 54 along a pressing direction A. The pressing assembly 54 also has a positioning body 543 defining a positioning channel, and the positioning column 528 of the outer rail 52 can extend through the positioning channel and be inserted into the positioning hole 562. The pressing assembly 54 is clamped and fixed by the outer rail 52 and the inner rail 56 during use. In particular, the positioning body 543 of the pressing assembly 54 remains substantially stationary relative to the outer rail 52 and / or the inner rail 56 during use. The pressing assembly 54 also has an elastic element 544. When the middle protrusion of the protrusion 526 of the outer rail 52 of the adjacent rail unit is inserted into the middle channel 5224 of the receiving channel of the rail unit 50, the elastic element 544 will be deformed by force to deform away from the pressing body 541 until the hook 5262 of the middle protrusion passes over the hook 5442 of the elastic element 544, after which the elastic element 544 will reset to limit the hook 5262 of the middle protrusion. In this way, the two adjacent rail units will be firmly engaged. When the user presses the pressing body 541 of the pressing assembly 54 along the pressing direction A, the elastic element 544 will be deformed by force to deform away from the pressing body 541, and the user can pull out one of the two adjacent rail units.

[0046] In some embodiments, the inner track 56 has a limiting post 568 for limiting the movement of the pressing body 541 operated by the user to prevent, for example, the integrated pressing assembly 54 from breaking.

[0047] In some embodiments, the track unit may further include a support member 58. The support member 58 may be in the form of a can, the upper end of which may be snapped into the inner track 56. The bottom surface of the support member 58 may be provided with a plurality of spherical or hemispherical elements 582.

[0048] Figure 8The track structure for the pulley of the slide is shown in detail. The outer track has an outer surface 5201 for sliding contact with the pulley, and the inner track has an outer surface 5202 for sliding contact with the pulley. The size of the spacing between the outer surface 5201 and the outer surface 5202 allows the pulley to slide smoothly therebetween. The outer track and the inner track also have stop features 5203 and 5204, respectively, to prevent the pulley from leaving the track.

[0049] In some embodiments, the weight element may have a closed housing, such as a soft plastic housing, with an opening to allow filling with water or sand or the like, and a cover of the weight element may close the opening and seal the housing. The housing of the weight element may have associated features to allow attachment of a tether.

[0050] Fig. 9 Two outer rails are shown during assembly, with other components of the track unit hidden. The protruding portion of the outer rail may include side protrusions 9262, 9266 and an intermediate protrusion 9264 located therebetween. As previously described, the intermediate protrusion 9264 is used for a snap connection between two adjacent outer rails or track units. The side protrusions 9262, 9266 are inserted into the side channels 5222, 5226 of the receiving channel 522, respectively. After assembly is completed, the distance between the end face 9263 of the side protrusion 9262 of the outer rail and the end face 9223 of the adjacent outer rail defining the side channel is in the range of 0.5mm-10mm, particularly in the range of 1mm-5mm, more particularly in the range of 1.5mm-3mm, for example 2mm. Similarly, after assembly, the distance between the end face 9267 of the side protrusion 9266 of the outer rail and the end face 9227 of the adjacent outer rail defining the side channel is in the range of 0.5 mm to 10 mm, particularly in the range of 1 mm to 5 mm, and more particularly in the range of 1.5 mm to 3 mm, for example, 2 mm. This design allows the pulley of the slide seat to slide on the annular path defined by the inner rail and the outer rail without passing through a long road with a notch (which will cause the movement of the slide seat to be blocked and cause a lot of noise). This design greatly reduces the generation of noise, and in combination with the pulley of the material described above, even silence can be achieved. The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the present invention. It should be pointed out that for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
