Description

Technical Field

[0001] This utility model relates to the field of fitness and office technology, specifically a fitness chair. Background Technology

[0002] As people gradually accept the concept of cross-fitness during work and study breaks, some fitness chairs have emerged. When you need to exercise, you can separate the chair from the foot pedal exercise device and then step on it. When you need to work or study, you can bring the chair and the foot pedal exercise device closer together, with the exercise device located under the seat of the chair and your feet on the foot pedals to maintain a reasonable sitting posture for work or study.

[0003] However, the existing connection structure between foot pedal fitness devices and seats still has the following shortcomings: 1. The foot pedal fitness device retracts while the seat remains stationary, making retraction or deployment relatively laborious. 2. Retraction or deployment is generally achieved through a linear drive mechanism, which increases energy consumption. 3. The fitness device and retraction / deployment mechanism are all based on the seat, making the manufacturing process relatively complex and costly. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a fitness chair that is convenient and labor-saving to retract or unfold, and relatively energy-saving.

[0005] The technical solution of this utility model is to provide a fitness chair, including a seat and a stationary foot pedal fitness device; the bottom of the seat has a movable structure; it also includes a linear sliding connection structure that allows the seat to retract or move away from the foot pedal fitness device; and it also includes a locking and unlocking structure disposed on the seat and controlling the locking or unlocking of the linear sliding structure to slide relative to it.

[0006] With the above structure, the fitness chair of this utility model has the following advantages:

[0007] Since the foot pedal exercise device is stationary, such as when placed directly under the middle of the desk, and relies on the movable structure at the bottom of the chair, such as the rolling wheels, and with a little force when both feet touch the ground, the chair slides flexibly, conveniently, and effortlessly relative to the foot pedal exercise device.

[0008] By utilizing the movable structure at the bottom of the seat, such as the rollers, one can bring the two feet together for work or study, or move them apart for exercise, thus saving energy.

[0009] Furthermore, since it is an improvement on the original seat and foot pedal fitness device, and is connected by a linear sliding connection structure, its manufacturing process is relatively simple, the manufacturing cost is relatively low, and the production efficiency is relatively high.

[0010] Furthermore, the stationary foot pedal is positioned lower than the ground level of the seat base, and its thickness is narrower than the seat width. The rear end of the foot pedal has a groove that mates with the front of the seat's upright sleeve. In its retracted state, the axis of the pedal axle is located directly below the front edges of the seat base. With this structure, the retracted foot pedal is mostly located under the seat base, allowing the feet to rest on the footrests, maintaining a comfortable and reasonable sitting posture for work or study.

[0011] Furthermore, the seat's movement mechanism consists of multiple casters. With this structure, the linear sliding process of the foot pedal exercise device, which remains relatively stationary on the seat, as it retracts or moves away, becomes more flexible, convenient, and effortless.

[0012] Furthermore, the linear sliding connection structure comprises at least one sliding sleeve and at least one sliding rod that slides within the sleeve. With this structure, the sliding mechanism is relatively simple, the cost is relatively low, and the installation and linear sliding process are relatively convenient.

[0013] Furthermore, the seat includes a column, the top of which is fixed to the bottom of the seat plate, and the bottom of which is fixed to a sliding sleeve. Each end of the sliding sleeve has a caster wheel, and each side of the sleeve has a support rod forming an angle with the sleeve. Each free end of the support rod is fitted with a caster wheel. This structure improves the seat's sturdiness and stability, and further ensures a more flexible, convenient, and effortless linear sliding motion of the foot pedal exercise device as it retracts or recedes from its relatively stationary position.

[0014] Furthermore, the sliding sleeves consist of two parallel rods, which are fixed to each other and to the uprights. Two sliding rods are used to slide in conjunction with their respective sliding sleeves, and the free ends of both rods are fixed to a fixed base. With this structure, the sliding sleeves themselves, as well as their support for the seat's uprights and seat, are more robust and stable. This also further ensures a more flexible, convenient, and effortless linear sliding process for the foot pedal fitness device, which moves in or out of position relative to the seat.

[0015] Furthermore, the two sliding sleeves are topped with front and rear top plates; the uprights are covered with upright sleeves; and the inner end of one top plate is connected to the upright sleeve. This structure further ensures a more robust and stable technical effect in terms of the sliding sleeve's structure and its support for the seat's uprights and seat, while also improving aesthetics and enhancing the user experience.

[0016] Furthermore, the locking and unlocking structure is as follows: One of the two parallel sliding sleeves is fixed with an elastic limiting pin. The front end of the elastic limiting pin engages with one of the row of limiting holes in the sliding rod inside the sleeve to limit or disengage the seat for sliding. The rear end of the elastic limiting pin is connected to one end of a steel wire rope of a flexible cable. The other end of the steel wire rope is connected to a steel wire rope pull wrench installed at the bottom of the seat. The elastic limiting pin contains a return spring that, when the steel wire rope pull wrench is released, causes the front end of the elastic limiting pin to engage with a limiting hole, ensuring that the front end of the elastic limiting pin always tends to engage with a limiting hole. With this specific structure, the locking or unlocking operation is reliable, stable, flexible, and convenient, further ensuring the stability and reliability of the seat during foot-operated exercise, retraction or unfolding, and office / study activities.

[0017] Furthermore, another sliding sleeve at the installation location of the elastic limit pin has a guide pulley that rotates one end of the wire rope 90°. One end of the flexible hose with the wire rope sleeve is fixed to the other sliding sleeve. The sleeve is laid on the other sliding sleeve and the column, passing through the inside of the column sleeve. The other end of the flexible hose sleeve is fixed to the wall of the wire rope pull end mounting box at the bottom of the seat plate. The other end of the wire rope of the flexible hose is fixed to the rotating body of the wire rope pull wrench hinged to the wire rope pull end mounting box. With the above more specific structure, the process of the wire rope pull wrench operating the elastic limit pin via the wire rope is more flexible, stable, convenient, and reliable, and also has an aesthetic effect, improving the user experience.

[0032] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that these descriptions of specific embodiments are intended to aid in understanding this utility model, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various specific embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0033] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9 As shown.

[0034] A preferred embodiment of this utility model fitness chair includes a seat 1 and a stationary foot pedal fitness device 2. The seat 1 has a movable structure at its bottom. The foot pedal fitness device is also called a foot-operated fitness device or a foot-operated fitness device.

[0035] A preferred embodiment of the fitness chair of this utility model further includes a linear sliding connection structure 3 in which the seat 1 is retracted or moved away from the foot pedal fitness device 2.

[0036] A preferred embodiment of the fitness chair of this utility model further includes a locking / unlocking structure 4 disposed on the seat 1 and controlling the linear sliding structure to lock or unlock relative to each other.

[0037] The stationary foot pedal exercise device 2 is lower in height than the seat 12 of the chair 1 from the ground, and its thickness is narrower than the width of the seat 12. The rear end of the foot pedal exercise device 2 is as follows: Figure 4 The right end shown has the same front side as the column sleeve 15 of the seat 1 described below. Figure 4 The groove 25 on the left side shown in the diagram, when retracted, has its axis located on both sides of the front edge 121 of the seat 1. Figure 4 Directly below the left side edges shown in the diagram. Each end of the pedal axle 21 is connected to its own footplate 24 via its own connecting rod 23.

[0038] The movable structure of seat 1 is preferably a plurality of rollers.

[0039] The linear sliding connection structure 3 consists of at least one sliding sleeve 31 and at least one sliding rod 32 that is slidably fitted within the sliding sleeve 31. The cross-sections of the sliding sleeve 31 and the sliding rod 32 may be rectangular.

[0040] The seat 1 may also include a column 11, the top of which is fixed to the bottom of the seat plate 12, and the bottom of which is fixed to a sliding sleeve 31. If both sliding sleeves 31 are fixed, each of the two sliding sleeves 31 has a caster wheel 13 fixed to its front and rear ends. Each of the two parallel and mutually fixed sliding sleeves 31 has a support rod 14 on each side, forming an angle with the sliding sleeve 31. Each free end of the support rod 14 is equipped with a caster wheel 13. The angle can be 30°-60°. It is easy to understand that the two parallel and mutually fixed sliding sleeves 31 are not only part of the linear sliding connection structure 3, but also, because the sliding sleeves have casters 13 at both ends and are fixed to the lower end of the column 11, they also function as leg supports for the seat 1, together with the two support rods 14 equipped with casters 13, forming the leg support of the seat.

[0041] As described above, the sliding sleeve 31 is preferably provided in two parallel parts. The two sliding sleeves 31 are fixed to each other and are both fixed to the lower end of the column 11. The two sliding rods 32 are used to slide in a one-to-one correspondence with their respective sliding sleeves 31. The free ends of the two sliding rods 32 are fixed to a fixed seat 22 of the foot pedal fitness device 2.

[0042] The two sliding sleeves 31 are provided with two top plates, front and rear. The front top plate 33 is the left top plate shown in Figure 4, and the rear top plate 34 is as shown in Figure 4. Figure 4 The right top plate is shown. The column 11 is covered by a column sleeve 15. A top plate, such as the inner end of the front top plate 33, is shown... Figure 4 The right end shown is connected to the column sleeve 15, with a smooth connection and integral molding, which has an aesthetic effect and improves the user experience. Then the top plate 34 is fixed to the top surface of the two sliding sleeves 31, such as by welding or by using multiple screws.

[0043] The preferred structure of the locking and unlocking structure 4 is as follows: one of the two parallel sliding sleeves 31 is fixed with an elastic limiting pin 41. The front end 4111 of the pin 411 of the elastic limiting pin 41 is used to pass through the pin through hole of the sliding sleeve 31 and then be inserted into one of the limiting holes 321 of a row of limiting holes 321 of the sliding rod 32 inside the sliding sleeve 31 to limit or disengage the limiting so as to slide the seat 1. The rear end 4112 of the pin 411 of the elastic limiting pin 41 is connected to one end 4211 of the wire rope 421 of a flexible hose 42. The other end of the wire rope 421 of the flexible hose 42 is connected to a wire rope pulling wrench 43 installed at the bottom of the seat plate 12. The elastic limiting pin 41 is provided with a return spring 44 that causes the front end 4111 of the pin 411 of the elastic limiting pin 41 to be inserted into a limiting hole 321 after the wire rope pulling wrench 43 is released.

[0044] The specific structure of the elastic limiting pin 41 can be as follows: an inner sleeve 413 is fixed on one of the sliding sleeves 31, the pin 411 is slidably fitted in the inner hole of the inner sleeve 413, a step 4113 is provided on the part of the pin 411 near the front end 4111, the rear end of the pin 411 is screwed and fixed to the center hole of a movable sleeve 412 by external and internal threads, a return spring 44, such as a compression spring or a support spring, is limited at one end on the step 4113, the other end of the return spring 44 abuts against the end plate of the movable sleeve 412, the movable sleeve 412 is slidably connected to the inner sleeve 413, the end of the movable sleeve 412 has a hook 4122, and a transverse hanging post 42111 of one end 4211 of the wire rope 421 is hooked in the hook 4122.

[0045] Pulling the wire rope 421 causes the horizontal hanging column 42111 to drive the movable sleeve 412 and pin 411 to slide backward against the spring force of the return spring 44. The front end of the pin 4111 disengages from the limiting hole 321, and the seat 1 can retract or unfold with the assistance of the feet. After the hand releases the wire rope and pulls the wrench 43, the spring force of the return spring 44 presses the step 4113 on the pin 411, causing the front end 4111 of the pin 411 to insert into a limiting hole 321 for limitation.

[0046] The specific arrangement of the flexible hose cable 42 can be as follows: A guide pulley 45 is located on another sliding sleeve 31 at the installation point of the elastic limiting pin 41, causing one end of the wire rope 421 to rotate 90°. One end of the sleeve 422 of the flexible hose cable 42, which contains the wire rope 421, is fixed to the other sliding sleeve 31. The sleeve 422 is laid on the other sliding sleeve 31 and the column 11, and passes through the column sleeve 15. The other end of the sleeve 422 of the flexible hose cable 42 is fixed to the wall of the wire rope pulling end mounting box 46 at the bottom of the seat plate 12. The other end 4212 of the wire rope 42 is fixed to the rotating body 431 of the wire rope pulling wrench 43, which is hinged to the wire rope pulling end mounting box 46. It is easy to understand that the sleeve 422, also called a flexible hose, is not an ordinary flexible hose; it is an inner lining ring formed by interconnected inner bushings or inner lining strips inside the flexible hose to increase strength.

[0047] In addition to multiple casters such as the four omnidirectional casters mentioned above, the moving structure of the seat can also consist of two guide rails parallel to the sliding sleeve and the sliding rod, and two chair legs fitted into the respective guide rails and supported by multiple ball bearings.

[0048] In addition to the two parallel sliding sleeves and corresponding sliding rods slidably fitted within their respective sleeves, the linear sliding connection structure relative to the foot pedal exercise device can also include a single sleeve and a sliding rod slidably fitted within that sleeve. Alternatively, it can consist of a guide rail and a sleeve supported by multiple rolling balls embedded within it, with the sleeve fixed to the seat column and one end of the guide rail fixed to the foot pedal exercise device. Another option is a chute and a slider slidably fitted with it, with one end of the chute fixed to the foot pedal exercise device, lubricant present between the slider and the chute, and the slider fixed to the seat column, etc.

[0049] The locking and unlocking structure for controlling the linear sliding mechanism to lock or unlock relative to the sliding mechanism, in addition to the structure described above where a wire rope pulls a wrench via a flexible hose to control the elastic limit pin, can also involve directly mounting the elastic limit pin on a sliding sleeve. Pulling the rear end of the elastic limit pin by hand overcomes the spring force, causing the front end of the pin to disengage from the limit hole and unlock the seat; or releasing the hand allows the spring force to engage the front end of the elastic limit pin in one of the limit holes in a row of limit holes on the sliding rod for relative positioning. Alternatively, a push-button switch can be installed at the bottom of the seat, electrically connected to an electromagnet-controlled elastic limit pin via a wire. When the push-button switch is powered on, the electromagnet attracts the rear end of the elastic limit pin, causing the front end of the pin to disengage from the limit hole and unlock the seat; or when the push-button switch is powered off, the electromagnet loses power and the spring force causes the front end of the elastic limit pin to engage in one of the limit holes in a row of limit holes on the sliding rod for relative positioning.

[0050] Components, structures, or quantities not marked above are not shown in the drawings, and some components are not marked in the drawings. The drawings are for illustrative purposes only. In case of any inconsistency between the drawings and the text description, or between the drawings themselves, the text description shall prevail.

[0051] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
