For the convenience of understanding, the specific structure and the working principle of the present disclosure are described in detail below with reference to fig. 1 to 5 in conjunction with the embodiments.

Referring to fig. 1, in one embodiment of the present disclosure, a hula hoop includes a hoop 1, a pulley mechanism 2, and a noise reduction structure (not shown, the noise reduction structure is disposed on the pulley mechanism 2).

The shape of the hoop 1 is the same as a conventional hula hoop, and the hoop 1 is configured to encircle the waist of a human body in a use state. For convenience of description, in terms of standing on a user, the ring 1 has an inner annular surface facing the user and an outer annular surface opposite to the inner annular surface, the outer annular surface has a certain width, the ring is further provided with an annular slide way 11, the annular slide way 11 is matched with the ring 1 in shape, and the pulley mechanism 2 is arranged on the ring 1 and can rotate along the annular slide way 11. Under the user state, the interior anchor ring of ring 1 contacts with the human body, the interior anchor ring of ring 1 can also be constructed as having a plurality of arch of inside extension, this arch and human body contact can increase the frictional force between the interior anchor ring of ring 1 and the human body, under the effect of frictional force between the interior anchor ring of ring 1 and the human body, ring 1 can be static relatively with the human body or can carry out small amplitude rotation with the human body, conveniently make almost all effects of external force at pulley mechanism 2, pulley mechanism 2 is under the effect of external force, do clockwise or anticlockwise's circular motion along annular slide 11 for the human body.

For the convenience of a user to sleeve the ring 1 on the waist, a splicing structure can be arranged on the ring, and the splicing structure can be spliced together in a buckling mode, for example, when the pulley mechanism is used, the user opens the buckle and inserts the ring 1 into the pulley mechanism 2, or the pulley mechanism 2 is sleeved on the ring 1 through the splicing position of the ring 1, and a pulley component of the pulley mechanism is contacted with the annular slide 11 of the ring 1, so that the pulley mechanism 2 can rotate along the ring 1; when the use is stopped, the user can open the buckle and slide the pulley mechanism 2 out of the ring 1.

The pulley mechanism 2 is mounted on the hoop 1, for example, the pulley mechanism 2 is mounted on the hoop 1 during use, and the pulley mechanism 2 is removed after use, so as to reduce the occupied space of the hula hoop. One side of the pulley mechanism 2, which is far away from the ring 1, can also be connected with a counterweight 4, and in the process that the pulley mechanism 2 rotates along the ring, the counterweight 4 and the pulley mechanism 2 synchronously rotate along the ring. Standing at the user's angle, the user can exert force to the weight 4, and after the weight 4 atress, can carry out clockwise rotation or anticlockwise rotation in the direction of being close to the level relative to the user, the pulley mechanism 2 that sets up on the circular slideway 11 can pull weight 4 along the direction motion of circular orbit, can also offset the centrifugal force of weight 4 simultaneously for weight 4 is around the human motion all the time through pulley assembly 2. The user is through exerting force to weight 4 to reach the purpose of taking exercise the health, simultaneously, can also adjust through the weight of adjusting weight 4 and temper intensity, satisfy different users' user demand.

Referring to fig. 2, the pulley mechanism 2 includes a pulley support and a pulley assembly, the pulley support is installed on the ring 1, and wraps the annular slideway 11 inside the pulley support, the pulley assembly is rotatably disposed on the pulley support, the pulley assembly is disposed on one side of the ring 1 where the inner ring surface is located, and contacts with the inner side of the annular slideway 11, and in the process that the pulley mechanism 2 rotates along the annular slideway 11, the annular slideway 11 supports the rotation of the pulley assembly, so as to prevent the pulley mechanism 2 from falling off.

In practical applications, a user may apply a force to the weight, the weight 4 drives the pulley mechanism 2 to rotate along the ring 1, the pulley support 21 rotates along the ring slideway 11 through the pulley assembly connected to the ring slideway 11, for example, the user applies a clockwise or counterclockwise force to the weight 4, and the weight 4 drives the pulley support to move along the ring slideway 21 in a clockwise or counterclockwise direction.

In the process that the pulley mechanism 2 rotates along the annular slide way 11, noise is generated due to friction between the pulley bracket 21 or the pulley assembly of the pulley mechanism 2 and the annular slide way 11, so the hula hoop disclosed by the disclosure further comprises a noise reduction structure, the noise reduction structure is arranged on the pulley mechanism and is constructed to reduce noise generated due to rotation friction when the pulley mechanism rotates along the annular slide way 11 under the condition that the original function of the pulley mechanism 2 is not changed.

To more clearly describe the specific noise reduction manner of the noise reduction structure when the pulley mechanism rotates along the circular track, the following embodiments will describe the structure and function of the noise reduction structure in detail with reference to the detailed structure of the hula hoop and the reason for generating noise in a specific use scenario.

In one embodiment of the present disclosure, referring to fig. 1, the pulley assembly comprises at least one pulley 211 rotatably disposed on the pulley bracket, the pulley 211 rotating in contact with the endless slide in the use state for supporting the entire pulley mechanism 2 in a horizontal direction to rotate along a loop. The noise reduction structure is an elastic outer wheel 31 sleeved on the outer ring surface of the pulley 211, and the outer ring surface of the elastic outer wheel 31 is directly contacted with the annular slideway 11, so that the pulley 211 is contacted and rotated with the annular slideway 11 through the elastic outer wheel 31.

It should be noted that, in order to make the pulley 211 have enough supporting force in the process of the pulley mechanism 2 rotating along the annular slideway, the pulley 211 is generally made of hard material, so that the pulley 211 is not deformed in the rotating process, and the rotation of the pulley mechanism 2 is more stable, but the hard pulley inevitably generates noise in the rotating process due to friction with the annular slideway, therefore, the elastic outer wheel sleeved on the outer edge of the pulley 211 not only can make the pulley 211 exert the supporting function greatly, but also can make the pulley 211 and the annular slideway 11 change from hard contact to soft contact, thereby effectively reducing the noise generated by the rotation friction between the pulley 211 and the annular slideway 11 in the process of the pulley mechanism 2 rotating along the annular slideway 11.

For example, when a user uses a hula hoop, a force is applied to the weight 3, the pulley mechanism rotates along the ring 1, the pulley 211 rotates in direct contact with the annular slideway 11, a large noise is generated during the rotation, and the user can easily detect the noise. After elasticity foreign steamer 31 is established to outer annular surface cover of pulley 211, through elasticity foreign steamer 31 and annular slide 11 direct contact for pulley 211 passes through elasticity foreign steamer 31 and annular slide 11 indirect contact and rotates, though unable complete noise elimination, under the circumstances that the cover was equipped with elasticity foreign steamer 31, the noise of production is minimum, is difficult for being perceived by the user, has realized reducing the noise that produces when pulley 22 rotates along annular slide 11 from this, has improved user's use impression.

In an embodiment of the present disclosure, the elastic outer wheel 31 may be a soft rubber outer wheel, and the material for manufacturing the soft rubber outer wheel may be rubber, silicone rubber, soft polyvinyl chloride, etc., so that the elastic outer wheel 31 has the capability of generating elastic deformation, and the hard contact is changed into the soft contact through the elastic deformation, so as to reduce the noise generated by hard friction. The material of the elastic outer wheel 31 is only exemplified in the present disclosure, and the material of the elastic outer wheel 31 may be any material having elasticity as known to those skilled in the art, and is not limited thereto.

Therefore, in the process of using the hula hoop, the pulley assembly plays a supporting role and is also a noise generating position, and the noise generated in the process of rotating the pulley 211 along the annular slide way 11 can be effectively reduced by sleeving the elastic outer wheel 31 on the outer annular surface of the pulley 211 of the pulley assembly.

In addition to the pulley assembly, other structures of the pulley mechanism may also generate noise due to friction with the annular slide, and in one embodiment of the present disclosure, referring to fig. 3, the pulley bracket 21 includes a frame body, and an upper frame arm 212 and a lower frame arm 213 disposed on the frame body and respectively disposed on the upper side and the lower side of the ring 1. When the pulley mechanism 2 is mounted on the ring 1, the frame body wraps the ring-shaped slide rail 11 by extending the upper frame arm 212 and the lower frame arm 213 in the direction of the inner ring surface of the ring 1.

The pulley bracket 21 is connected to the ring 1 through two sets of pulley assemblies respectively arranged on the upper frame arm 212 and the lower frame arm 213, the inner surface of the ring 1 is provided with two annular slideways 11, and the pulleys 21 of the two sets of pulley assemblies are respectively contacted with the annular tracks 11 at corresponding positions.

The pulley assembly in this embodiment has the same structure and function as those of the pulley assembly described in the above embodiments, and the elastic outer wheels 31 are disposed on the shifting wheels 211 of the pulley assembly, and the structure and function of the elastic outer wheels 31 are also the same as those of the above embodiments, and are not described again here.

It should be noted that, two sets of pulley assemblies and two annular slide 11 have been set up in this affair example, on the one hand, two sets of pulley assemblies can support pulley mechanism 2 jointly and rotate along ring 1 for pulley mechanism 2 is more stable at the pivoted in-process, on the other hand, two sets of pulley mechanisms share the pressure of being produced by counterweight 4 along the rotation of annular slide jointly, can make the pressure between every pulley 211 and the annular slide reduce, also the friction between pulley 211 and the annular slide 11 reduce, and then reduced because of pulley 211 when rotating along annular slide 11, the noise that the friction produced. It is known to those skilled in the art that reducing the frictional force can reduce the noise generated by the friction, and the detailed description thereof will not be provided.

In practical application, the ring 1 is generally in a nearly horizontal state after being sleeved on the waist of a human body, the upper arm 212 of the pulley bracket is pressed against the outer edge of the upper side of the annular slideway 11 by the pulley mechanism arranged on the ring under the action of gravity, and the annular slideway supports the upper arm 212 of the pulley bracket 11 in the vertical direction, so that the outer edge of the annular slideway is in direct contact with the upper arm 212. Because the counterweight is connected with the pulley mechanism 2, the gravity of the counterweight also acts on the pulley mechanism 2, so that the pulley mechanism inclines obliquely downwards, and the outer edge of the upper side of the annular slideway is directly contacted with the upper frame arm 212; under the action of external force, the weight member may generate a centrifugal force obliquely upward relative to the ring, so that the pulley mechanism 2 is driven by the weight member to obliquely upward relative to the ring, and at this time, the outer edge of the lower side of the annular slide 11 is in direct contact with the lower frame arm 213. Therefore, in both cases, there is a possibility that the upper arm 212 and the lower arm 213 generate contact friction with the circular slide 11, resulting in generation of noise.

It should be noted that the frame arm on any side of the frame body may be an upper frame arm or a lower frame arm, and any side of the annular slide way may be an upper side or a lower side.

With continued reference to fig. 3, during the rotation of the pulley mechanism 2 along the annular slide, the upper arm 212 and the lower arm 213 of the pulley support may contact the annular slide 11, so that friction occurs and noise is generated, and therefore, the noise reduction assembly is an elastic friction plate disposed between the opposite surfaces of the upper arm 212 and the ring 1.

In detail, the upper arm 212 and the lower arm 213 facing the side of the circular slideway may contact with the outer edge of the circular slideway 11, and the contact friction may generate great noise during the rotation of the pulley bracket along the circular slideway, so that a set of elastic friction plates 32 are respectively added on the arm surfaces of the upper arm 212 and the lower arm 213 facing the side of the circular slideway, thereby reducing the noise.

In one embodiment of the present disclosure, the elastic friction plate 32 may be disposed on the upper frame arm 212, a side of the elastic friction plate 32 facing the upper frame arm 213 is fixedly connected to the upper frame arm, a side of the elastic friction plate 32 facing the annular slide way 11 is configured to be a smooth surface, and the elastic friction plate directly contacts the annular slide way during the rotation of the pulley bracket along the annular slide way 11, so that a sliding friction force is reduced due to the smooth surface of the elastic friction plate contacting the annular slide way 11, thereby reducing noise.

In another embodiment of the present disclosure, the elastic friction sheet 32 may be disposed on the ring, a side of the elastic friction sheet 32 facing the annular slideway 11 is fixedly connected to the annular slideway 11, a side facing the upper arm 212 is configured as a smooth surface, and during the rotation of the pulley bracket along the annular slideway 11, the elastic friction sheet is in direct contact with the upper arm 212, and the sliding friction force is reduced because the surface of the elastic friction sheet in contact with the upper arm 212 is smooth, thereby reducing noise.

In one embodiment of the present disclosure, the elastic friction plate 32 includes a silicone sheet and a teflon sheet that are stacked. The silica gel sheet is made of soft rubber materials, and can play a role in shock absorption and skid resistance; the Teflon sheet has the characteristic of smooth surface, is similar to a foot pad of a mouse, and can effectively reduce friction force.

In practical application, the silicone sheet may be fixedly connected to the upper arm 212, the lower arm 213, or the annular slide way, and the teflon sheet may be used to replace the direct contact between the upper arm 212 or the lower arm 213 and the annular slide way 11, so as to reduce friction.

It should be noted that the mounting position of the elastic friction plate 32 can be selected according to actual conditions, and the elastic friction plate 32 is mounted on the outer edges of the upper frame arm 212, the lower frame arm 213 and the annular slideway to reduce friction between the upper frame arm 213 or the lower frame arm 213 and the annular slideway 11.

Considering that, under the action of gravity or external force, the pulley mechanism 2 may form a certain inclination angle with respect to the outer ring surface of the ring 1, so that the frame body of the pulley bracket contacts with the outer ring surface of the ring 1, and the frame body rubs against the outer ring surface of the ring 1 to generate noise in the process that the pulley mechanism 2 rotates along the ring 1.

To solve the above problem, in one embodiment of the present disclosure, the noise reducing structure further includes a support wheel 33 rotatably disposed on at least one of the upper arm 212 and the lower arm 213, and the support wheel 33 may abut against an outer annular surface of the collar.

In practice, at least one support wheel 32 may be provided on the upper arm 212 and the lower arm 213, respectively. During the rotation of the pulley mechanism 1 along the ring 1, under the action of gravity, the pulley bracket will incline downwards relative to the ring 1, the support wheel 32 on the lower frame arm 213 will abut against the outer ring surface of the ring 1, and the support wheel 32 will rotate in contact with the outer ring surface of the ring 1; alternatively, when the pulley holder is tilted upward by an external force, the support wheels 32 of the upper arm 212 are abutted against the outer circumferential surface of the ring 1, and the support wheels 32 are rotated in contact with the outer circumferential surface of the ring 1. In both cases, the support wheels 32 abut against the outer circumferential surface of the ring 1 regardless of whether the pulley holder is inclined downward or upward, thereby further reducing noise generated by sliding when the pulley holder is in direct contact with the outer circumferential surface of the ring 1.

In one embodiment of the present disclosure, referring to fig. 3, the pulley bracket includes a frame body, and an upper arm 212 and a lower arm 213 disposed on the frame body and respectively disposed on upper and lower sides of the loop 1. When the pulley mechanism 2 is mounted on the ring 1, the frame body wraps the ring-shaped slide rail 11 by extending the upper frame arm 212 and the lower frame arm 213 in the direction of the inner ring surface of the ring 1.

The noise reducing structure further comprises a support wheel 33 rotatably arranged on at least one of the upper arm 212 and the lower arm 213, the support wheel 33 being abuttable against an outer circumferential surface of the collar 1.

The function of the supporting wheel 33 in this embodiment is identical to the structure and function of the supporting wheel 33 in the above embodiments, and will not be described again.

The two pulley assemblies in this embodiment have the same structure and function as those in the previous embodiments, and the elastic outer wheel 31 is disposed on the shifting wheel 211 of the two pulley assemblies, and the structure and function of the elastic outer wheel 31 are also the same as those in the previous embodiments, and are not described again here.

Unlike the previous embodiment, referring to fig. 4 and 5, in the present embodiment, each set of pulley assemblies includes at least three pulleys 211 sequentially arranged along the extending direction of the annular sliding way 11, the three pulleys 211 are all in contact with the annular sliding way 1 during the rotation, and the three pulleys 211 can share the pressure during the rotation, so as to reduce the friction between each pulley 211 and the annular sliding way 11, and further reduce the noise.

In addition, in order to make the hula hoop of the present disclosure encircle the waist of a person, the opening connected by the buckle is arranged on the hoop 1, and when in use, the opening can be opened, so that the hoop 1 can be smoothly encircled on the waist of a human body. However, due to manufacturing errors or the structure of the loop 1, a seam is formed at the opening position of the loop, so that noise is generated by contact when the pulley 211 passes through the seam.

In the embodiment of the present disclosure, at least three pulleys 211 are sequentially arranged along the extending direction of the annular sliding way 11, when one pulley 211 passes through the seam, the other two pulleys 211 play a main supporting role, that is, the pressure between the pulley 211 and the seam of the seam is small, so that the noise generated when the pulley 211 passes through the seam is reduced.

In conclusion, the hula hoop disclosed by the invention can effectively reduce the noise generated by friction when the pulley mechanism 2 rotates along the ring 1 by arranging the noise reduction structure, so that the use feeling of a user is improved.
