Description

Technical Field

[0001] This utility model relates to the field of sports furniture technology, specifically a rhythmic backrest chair. Background Technology

[0002] With social development and improved living standards, modern people are paying more and more attention to health and exercise. However, due to the fast pace of modern life, people do not have enough time to exercise. Long-term lack of exercise can easily lead to a decline in physical function. Studies have shown that human vibration can effectively exercise the body's muscle groups and enhance physical fitness. Therefore, rhythmic equipment products with vibration effects have emerged.

[0003] Most exercise machines on the market are currently upright, meaning users stand on them while the machine vibrates to create a workout effect. However, upright exercise machines cannot meet the needs of people who do not have enough time or cannot stand for extended periods.

[0004] To address the above shortcomings, we need to develop a rhythmic backrest chair to meet the needs of a wide range of users. Utility Model Content

[0005] The purpose of this invention is to provide a rhythmic backrest chair that allows users to perform rhythmic exercises while sitting with the backrest in place, thus solving the problem that existing rhythmic devices require users to stand up and cannot meet their needs.

[0006] A rhythmic backrest chair includes a seat body and a rhythmic device detachably connected to the seat body. The rhythmic device includes a support frame, a rhythmic frame disposed below the seat body and movably connected to the support frame, and a rhythmic mechanism for driving the rhythmic frame to vibrate vertically relative to the support frame. The rhythmic mechanism is disposed between the support frame and the rhythmic frame.

[0007] The rhythm mechanism includes a base mounted on the support frame and a magnetic vibration assembly for generating vertical rhythm, the magnetic vibration assembly being disposed between the rhythm frame and the base.

[0008] The magnetic vibration assembly includes a permanent magnet, a magnetic ring, and an electromagnetic coil. The permanent magnet is installed on the side of the rhythm frame close to the magnetic vibration assembly, and the magnetic ring is installed on the side of the permanent magnet away from the rhythm frame. The electromagnetic coil is sleeved on the base, and both the permanent magnet and the magnetic ring extend into the space where the electromagnetic coil is sleeved.

[0009] The rhythm mechanism includes a guide assembly installed between the support frame and the rhythm frame. The guide assembly includes a vertically arranged guide sleeve and a guide rod for extending into the guide sleeve. The guide rod can reciprocate along the inner wall of the guide sleeve. At least three of the guide assemblies are arranged circumferentially around the base of the rhythm mechanism.

[0010] The rhythmic mechanism includes a buffer assembly installed between the support frame and the rhythmic frame. The buffer assembly includes an elastic element and mounting parts located at both ends of the elastic element.

[0011] The mounting component includes a mounting base, a mounting post disposed on the mounting base for the elastic element to be fitted, and a limiting plate for preventing the elastic element from disengaging from the mounting post. The limiting plate is spirally arranged around the outer periphery of the mounting post.

[0012] The rhythmic mechanism is equipped with foot pads for stable placement. The foot pads are located below the main body of the chair seat and are connected to the support frame via elastically deformable foot pad brackets.

[0013] At least three of the foot pads are circumferentially spaced around the center of the support frame and arranged on the outer edge of the support frame.

[0014] The rhythmic mechanism also includes a protective shell for protecting the internal structure, and the protective shell is provided with multiple ventilation and heat dissipation vents spaced around the center.

[0015] The main body of the chair has an armrest, a leg support, and a backrest. The armrest includes a left armrest a and a right armrest b respectively located on the left and right sides. The leg support is inclined relative to the horizontal plane to form an angle c. The backrest is inclined relative to the horizontal plane to form an angle d. Both angle c and angle d are inclined in the same direction and form an acute angle.

[0016] The beneficial effects of this utility model are as follows: This utility model's rhythmic backrest chair features a rhythmic device detachably connected to the main seat. The rhythmic mechanism within the device drives the main seat vertically, enabling users to engage in rhythmic exercise while seated. This effectively meets user needs, and the vertical rhythm reduces vibration discomfort, enhancing the fitness effect of the exercise. It avoids the dizziness caused by horizontal vibrations, as is common with traditional methods. Furthermore, the detachable connection of the rhythmic device allows for easy installation with chair seats of different sizes. The device can also be removed, returning the chair to its original seat position, offering versatility to meet home use needs and improve its adaptability. Attached Figure Description

[0022] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0023] Example 1: like Figures 1 to 4 The illustrated rhythmic backrest chair includes a seat body 1 and a rhythmic device 200 detachably connected to the seat body 1. The rhythmic device 200 includes a support frame 2, a rhythmic frame 3 located below the seat body 1 and movably connected to the support frame 2, a rhythmic mechanism 4 for driving the rhythmic frame 3 to vibrate vertically relative to the support frame 2, and a power supply (which can be powered by an independent battery or plugged into a household power outlet). The rhythmic mechanism 4 is located between the support frame 2 and the rhythmic frame 3.

[0024] Specifically, in this embodiment, the chair body 1 is a backrest chair for users to sit on, and the rhythm device 200 is a power device installed at the bottom of the chair body 1 to generate rhythm. The support frame 2 is a frame for the rhythm device 200 to support the chair body 1 and provide stable placement on the ground. The rhythm frame 3 is a frame for the rhythm device 200 to be installed and connected to the chair body 1 for stable installation. The rhythm mechanism 4 is the power mechanism for the rhythm device 200 to generate regular vibrations. The rhythm mechanism 4 is located between the support frame 2 and the rhythm frame 3, so that the rhythm mechanism 4 can directly drive the rhythm frame 3 as a power source to move the chair body 1 vertically and act on the user's body to perform rhythmic exercise. The principle of the whole-body vertical rhythm is to generate an upward thrust against gravity through mechanical force. When this thrust stops, the person standing on it will fall downward by gravity. At this time, an upward thrust is applied to him again, forming a rapid vertical reciprocating impact force. The human body mainly transmits this force through bones, muscles, and spine, thus stimulating the entire musculoskeletal and nervous system. The effect of vertical rhythmic movement can improve the body's musculoskeletal and nervous system, further improving the endocrine and other physiological systems, producing various health benefits and enhancing the fitness effect of rhythmic exercise. Vertical rhythmic movement can reduce user discomfort from vibration and avoid the dizziness caused by horizontal vibration as in traditional methods.

[0025] Example 2: Based on Example 1, such as Figures 1 to 4 The illustrated rhythmic backrest chair has a rhythmic mechanism 4 including a base 41 mounted on a support frame 2 and a magnetic vibration component 42 for generating vertical rhythmic motion, the magnetic vibration component 42 being disposed between the rhythmic frame 3 and the base 41.

[0026] Specifically, in this embodiment, the rhythm mechanism 4 uses magnetic drive to generate regular vertical vibrations on the rhythm frame 3. The magnetic vibration component 42 includes a permanent magnet 421, a magnetic ring 422, and an electromagnetic coil 423. The permanent magnet 421 is installed on the side of the rhythm frame 3 close to the magnetic vibration component 42, and the magnetic ring 422 is installed on the side of the permanent magnet 421 away from the rhythm frame 3. The electromagnetic coil 423 is sleeved on the groove structure corresponding to the outer side wall of the base 41. The groove structure is an annular groove arranged circumferentially around the outer side wall of the base 41. Both the permanent magnet 421 and the magnetic ring 422 extend into the inner side wall of the base 41 and are located within the space where the electromagnetic coil 423 is sleeved.

[0027] In use, the effective magnetic permeability of the permanent magnet 421 and the magnetic ring 422 is concentrated at their edges, forming an effective magnetic field with the electromagnetic coil 423. After the electromagnetic coil 423 is energized, the direction of the current is changed alternately to generate magnetic fields with different polarities. These magnetic fields repel each other or attract each other with the inherent magnetic fields of the permanent magnet 421 and the magnetic ring 422. Thus, the magnetic field polarity drives the rhythm frame 3 to drive the chair body 1 to form a regular vertical vibration effect.

[0028] Based on Embodiment 2, as another Embodiment 201 of Embodiment 2, in this embodiment, the rhythm mechanism 4 uses magnetic drive to generate regular vertical vibrations of the rhythm frame 3. The magnetic vibration component 42 includes a permanent magnet 421, a magnetic ring 422, and an electromagnet. After the permanent magnet 421 extends into the base 41, it is pressed against the bottom of the base 41 by a spring. The electromagnet is installed in the middle of the spring. When the electromagnet is energized, it alternately changes the direction of the current, so that it generates a force that repels like poles or attracts unlike poles on the permanent magnet 421. This causes the permanent magnet 421 to be magnetically attracted and move downwards, or magnetically repelled and move upwards. Thus, the magnetic field polarity drives the rhythm frame 3 to drive the chair body 1 to form a regular vertical vibration.

[0029] Example 3: Based on Example 2, in order to enhance the stable and directional movement of the rhythm mechanism 4 when generating rhythm, such as Figures 1 to 5 The illustrated rhythmic backrest chair includes a rhythmic mechanism 4 comprising a guide assembly 5 installed between a support frame 2 and a rhythmic frame 3. The guide assembly 5 includes a vertically arranged guide sleeve 51 and a guide rod 52 for extending into the guide sleeve 51. The guide sleeve 51 may be a hollow cylindrical structure with its central axis arranged vertically. The guide rod 52 may be a round bar structure and can reciprocate along the inner wall of the guide sleeve 51. At least three guide assemblies 5 are arranged circumferentially around the base 41 of the rhythmic mechanism 4. The multiple guide assemblies 5 simultaneously restrict the directional movement of the rhythmic mechanism 4 and resist the force that causes the rhythmic backrest chair to tilt to one side.

[0030] Example 4: Based on Example 1, in order to reduce the mechanical shaking and impact of the rhythm mechanism 4 when generating rhythm, such as Figure 5The illustrated rhythmic backrest chair includes a rhythmic mechanism 4 comprising a buffer assembly 6 installed between a support frame 2 and a rhythmic frame 3. The buffer assembly 6 includes an elastic element 61 and mounting pieces 62 disposed at both ends of the elastic element 61. The elastic element 61 may be a spring structure or a spring sheet structure. The mounting pieces 61 are used to fix the installation position of the elastic element 61 between the support frame 2 and the rhythmic frame 3. By buffering the mechanical shaking impact through the elastic element 61, the user can reduce the discomfort caused by the mechanical shaking impact, and the user's experience is improved in the direction of elastic shaking.

[0031] Example 5: Based on Example 4, such as Figure 5 The illustrated rhythmic backrest chair includes a mounting component 62 comprising a mounting base 621, a mounting post 622 disposed on the mounting base 621 for the elastic element 61 to be fitted onto, and a limiting plate 623 for preventing the elastic element 61 from disengaging from the mounting post 622. The limiting plate 623 is spirally wound around the outer periphery of the mounting post 622. In use, the elastic element 61 is inserted into the spiral structure gap of the limiting plate 623, and can be securely installed on the mounting post 622. Utilizing the anti-return self-locking characteristic of the spiral structure, the elastic element 61 is prevented from disengaging axially along the mounting post 622, and the mounting post 622 restricts the elastic element 61 from disengaging radially relative to itself, thus preventing the elastic element 61 from falling off due to long-term vibration. The limiting effect of the reinforced installation is good.

[0032] Example 6: Based on Example 1, such as Figures 1 to 4 The illustrated rhythmic backrest chair has a rhythmic mechanism 4 equipped with a foot pad 7 for stable placement. The foot pad 7 is located below the main body 1 of the chair seat and is connected to the support frame 2 via an elastically deformable foot pad bracket 8. The foot pad 7 can be made of soft rubber material with a certain surface friction. By utilizing the friction generated by the foot pad 7 contacting the ground, the placement of the rhythmic backrest chair is more stable, preventing the chair from shifting along the ground due to vibration or the force generated by the user lying down.

[0033] Based on Example 6, as another Example 601, such as... Figures 1 to 4 The rhythmic backrest chair shown has at least three foot pads 7 arranged circumferentially around the center of the support frame 2 on the outer edge of the support frame 2. Preferably, four foot pads 7 are arranged on the outer edge of the support frame 2. The multi-point arrangement can improve the stability of the rhythmic backrest chair when it is placed on the ground and reduce the lateral force on the rhythmic device 200 when the main body of the chair 1 is oriented to one side.

[0034] Example 7: Based on Embodiment 1, in order to better dissipate heat and protect the interior of the rhythm device 200, such as Figures 1 to 3The rhythmic backrest chair shown includes a rhythmic mechanism 4 that further includes a protective shell 9 for protecting the internal structure. The protective shell 9 can block the damage and influence of the external environment on the internal structure. The protective shell 9 is provided with a plurality of ventilation and heat dissipation vents 91 arranged circumferentially around the center, preferably with four ventilation and heat dissipation vents 91 evenly spaced circumferentially, so that the passing airflow can generate a counter-convective effect and improve the efficiency of air cooling.

[0035] Example 8: like Figures 1 to 3 The illustrated rhythmic backrest chair has a main seat 1 with armrests 11, leg supports 12, and a backrest 13. The armrests 11 include a left armrest a and a right armrest b respectively located on the left and right sides. The support height of both the left armrest a and the right armrest b is higher than the seating height of the middle seat. The leg supports 12 extend outward from the middle seat and slope downward, forming an angle c relative to the horizontal plane. The backrest 13 extends outward from the middle seat and slopes upward, forming an angle d relative to the horizontal plane. Both angles c and d slope in the same direction and form acute angles. Angle c is preferably 45 degrees and 60 degrees, and angle d is preferably 40 degrees, 50 degrees, and 60 degrees. This tilt angle is more in line with ergonomic design and improves the user experience.

[0036] The above examples are merely illustrative of the technical content of this utility model to facilitate reader understanding, but do not imply that the implementation of this utility model is limited to these embodiments. Any technical extensions or re-creations made based on this utility model are protected by this utility model. The scope of protection of this utility model is defined by the claims.
