Technical Field

[0001] This utility model relates to the field of fitness equipment technology, specifically to a hula hoop. Background Technology

[0002] Hula hoops are a popular fitness tool. Their spring structure makes them widely popular due to their ability to exercise multiple body parts and their portability. However, current spring hula hoops typically have plastic spring tubes on the outside. These tubes produce a loud noise when they collide with the inner metal spring tubes, resulting in excessive noise during use. Furthermore, frequent impacts can cause discoloration and lint, staining the user's clothing. Therefore, there is an urgent need to design a hula hoop that addresses these issues. Utility Model Content

[0003] To address the problems of excessive noise and easy shedding of debris in current spring hula hoops, this invention provides a new type of hula hoop.

[0004] The technical solution of this utility model is as follows: On the one hand, this utility model provides a hula hoop, characterized in that: it includes a spring ring assembly, including a metal spring ring; and an annular cloth sleeve, which is fitted on the outside of the metal spring ring and can cover the entire outer surface of the metal spring ring.

[0005] Furthermore, the annular fabric sleeve has an extension portion, which is used to extend to adapt to the stretched state when the metal spring coil is stretched.

[0006] Furthermore, the annular fabric cover has multiple stretchable pleats.

[0007] Furthermore, the annular fabric sleeve is elastic.

[0008] Furthermore, the two ends of the annular cloth sleeve are connected to each other; and / or, the annular cloth sleeve is configured to be detachably fitted onto the outside of the metal spring coil.

[0009] Furthermore, the spring coil assembly also includes a connector, the two ends of which are respectively connected to the beginning and end of the metal spring coil.

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by a person of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0020] The following disclosure provides numerous different embodiments or examples for implementing various structures of this application. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of this application. Furthermore, reference numerals and / or letters may be repeated in different examples.

[0021] For ease of description, spatial relative terms may be used in this text to describe the relative position or movement of one element or feature relative to another element or feature, as shown in the figure. These relative terms include, for example, "inside," "outside," "middle," "outer," "below," "below," "above," "front," "back," etc. Such spatial relative terms are intended to include different orientations of the device in use or operation, other than those depicted in the figure. For example, if the device in the figure undergoes a positional flip, orientation change, or change of motion, these directional indications will change accordingly. For instance, an element described as "below other elements or features" or "below other elements or features" will subsequently be oriented "above other elements or features" or "above other elements or features." Therefore, the example term "below" can include both upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions), and the spatial relative descriptors used in this text will be interpreted accordingly.

[0022] This application discloses a hula hoop, including a spring coil assembly 100 and an annular cloth sleeve 200. The spring coil assembly 100 includes a metal spring coil 110. The annular cloth sleeve 200 is sleeved on the outside of the metal spring coil 110 and can cover the entire outer surface of the metal spring coil 110.

[0023] In this embodiment, the metal spring ring 110 serves as the annular rotating base for the hula hoop, providing good elasticity and a long service life. The annular cloth sleeve 200 is fitted over the outside of the metal spring ring 110 and covers its entire outer surface, thus preventing direct contact between the metal and the user's body and providing isolation and protection. The annular cloth sleeve 200 also prevents dirt from entering the interior of the metal spring ring 110, thereby increasing its service life and maintaining cleanliness. Furthermore, since the annular cloth sleeve 200 is made of flexible fabric, it does not have a hard contact with the metal spring ring 110 compared to a plastic sleeve. Therefore, it is less prone to discoloration or flaking due to impact, and it does not generate noise, making it suitable for widespread use.

[0024] In an optional or preferred embodiment, the annular cloth sleeve 200 has an extension portion, which is used to extend to adapt to the stretched state of the metal spring coil 110 when it is stretched. For example, when a user uses the hula hoop, the metal spring coil 110 is stretched. At this time, since the annular cloth sleeve 200 has an extension portion, the annular cloth sleeve 200 will extend along with the stretching of the metal spring coil 110, thereby avoiding the tendency of the annular cloth sleeve 200 itself to tear. Furthermore, the extension portion is set to be stretchable, for example, elastic, so that the annular cloth sleeve 200 can always maintain a relatively stable fit with the metal spring coil 110, ensuring the normal use of the hula hoop.

[0025] In an optional or preferred embodiment, the annular fabric sleeve 200 has multiple telescopic pleats 210. By providing multiple telescopic pleats 210 on the annular fabric sleeve 200, the annular fabric sleeve 200 maintains a mating state with the metal spring ring 110, so that the annular fabric sleeve 200 adapts to the expansion and contraction of the metal spring ring 110. Moreover, the design of providing telescopic pleats 210 on the annular fabric sleeve 200 has a relatively mature manufacturing process and low processing cost.

[0026] In an optional or preferred embodiment, the annular cloth sleeve 200 is elastic, thereby better accommodating the elongation and shortening of the internal metal spring coil 110.

[0027] In an optional or preferred embodiment, the two ends of the annular cloth sleeve 200 are connected to each other, which can also serve as a safety rope to prevent the metal spring coil 110 from breaking accidentally or the spring from becoming uncontrollable due to the disconnection of the two ends of the spring for other reasons. Optionally, the connection can be made by sewing. Optionally, a circular piece with external teeth is used as a support on the inner side of the joint of the two ends of the annular cloth sleeve 200, and two semi-circular pieces with internal teeth are used to press it firmly on the outside. Further, it is welded with ultrasonic waves. Optionally, a circular piece with external teeth is used as a support on the inner side of the joint of the two ends of the annular cloth sleeve 200, and it is fixed with tape or latex tube on the outside.

[0028] In an optional or preferred embodiment, the annular cloth sleeve 200 is configured to be detachably fitted over the metal spring ring 110 so that it can be easily disassembled and replaced when the annular cloth sleeve 200 itself is damaged or dirty; optionally, the annular cloth sleeve 200 is provided with a detachable connection interface along its circumference.

[0029] In an optional or preferred embodiment, the spring coil assembly 100 further includes a connector 120, the two ends of which are respectively connected to the beginning and end of the metal spring coil 110 to form a hula hoop structure; the connection method between the connector 120 and the metal spring coil 110 can be one or more of the following: slot structure connection, interference fit, and fixed locking connection.

[0030] In an optional or preferred embodiment, an annular safety rope 300 is provided inside the metal spring coil 110. The annular safety rope 300 serves as a safety guarantee to prevent accidents caused by the accidental separation of the two ends of the metal spring coil 110. It can effectively avoid uncontrollable phenomena when the metal spring coil 110 breaks accidentally. The annular safety rope 300 is only one possible implementation method. Since the annular cloth sleeve 200 is connected end to end, the annular cloth sleeve 200 itself has the function of a safety rope and should not be regarded as a limitation.

[0031] In an optional or preferred embodiment, the first and last ends of the loop safety rope 300 are respectively connected to the two ends of the connector 120; by using the same connector 120 to connect the first and last ends of the metal spring coil 110 and the first and last ends of the loop safety rope 300, the overall structure of the hula hoop is more compact, and the assembly process of the hula hoop is also easier.

[0032] In an optional or preferred embodiment, the connection point between the loop safety rope 300 and the connector 120 is located inside the circumferential cross-section of the metal spring coil 110. The inner loop design of the loop safety rope 300, combined with the outer loop design of the metal spring coil 110, makes the hula hoop's structural design reasonable and compact.

[0033] In an optional or preferred embodiment, the metal spring coil 110 has at least a tendency to deform along its axial direction and a tendency to deform along its radial direction to suit the requirements of hula hoop use; for example, a soft spring may be used.
