Description

TECHNICAL FIELD

[0001] The present application relates to a swing adjustment and rotation structure of a seat of an exercise bike, and more particularly, to a swing adjustment and rotation structure of a seat of an exercise bike, which induces left and right swings of the seat and a buffering effect of dispersing a load when a user sits on the seat of the exercise bike and pedals, enables a user to directly adjust a range of motion of a hip joint, and ensures stability of movement of a pelvis and a spine while pedaling, and enables a user to arbitrarily adjust a swing range of the seat while exercising a lower body, in order to match core muscle training and a body type of an athlete. BACKGROUND

[0002] Nowadays, most of the time that modern people are awake is in a sitting position. With the repetition of such a lifestyle, it is possible to suffer from chronic physical diseases such as obesity. In addition to obesity, it is possible to suffer from a scoliosis disease in which a spine is curved to the left or right due to the curvature of the spine, which causes problems in the entire body muscles and is accompanied by nervous system diseases. In this regard, modern people mostly use physical exercise as an important element in daily life until they suffer from obesity, scoliosis, and the like, in order to minimize the deterioration of physical functions.

[0003] When modern people start exercising, a bicycle exercise machine using a pedal is mainly used as a preventive measure against physical diseases, and this is widely used and widely used as a representative aerobic exercise machine for training a lower body or burning fat in the body.

[0004] Through exercise bike exercise, it is possible to achieve the effects of weight loss and decomposition of fat in the body, development of lower body muscles, prevention of joint diseases, prevention of migraines, and prevention of diabetes, which are effects that can be achieved only by long-term and regular exercise. In addition, since the device also exercises while maintaining a sitting position on a fixed seat, if the stability of the spine movement corresponding to the range of motion of the hip joint and the flexibility are not sufficiently considered, it can have an impact on the spine of a person who has a basic disease such as scoliosis, can cause a burden to the spine, and can cause a burden to the hip joint of an obese person.

[0005] In addition, since the left and right swing widths according to the physical conditions of each user are fixed, it is necessary to adjust the swing widths.

[0006] In order to improve the above problems, there have been many studies on exercise bikes from ancient times, and for example, Korean Patent Registration No. 10-1160587 discloses a technical idea for a seat of a bicycle having a sitting exercise function. The technical idea prevents unnecessary twisting of the seat when exercising in a sitting position, but does not actively consider the flexibility of the motion of the hip joint and cannot reflect the physical conditions of a user. SUMMARY

[0031] The eccentric rotation part has a fixing plate surrounding the outer surface of the height adjustment rod and being kept in place, a rotation connecting part extending from the fixing plate and provided with a protrusion protruding upward from a set position, and a rotation control part configured to be combined with the protrusion of the rotation connecting part and capable of simultaneously enlarging or reducing the rotation radius by eccentric rotation while maintaining the combined state,

[0032] The rotation control part includes a main body connected to the rotation connecting part and having a hollow area formed by a set distance, a medium-length bolt longitudinally passing through the center of the main body, a holding part guided by the user's grip by left-right rotating keys by protruding or protruding or forming a key groove from the end of the medium-length bolt, and a position adjustment part provided in the hollow area of the main body, fixed to the medium-length bolt, and changing the position in the hollow area of the main body by thread by rotating the medium-length bolt by operating the holding part.

[0033] The advantages and features of the present application and the method of implementation will become apparent from the following embodiments described in detail with reference to the accompanying drawings. However, the present application is not limited to the following disclosed embodiments, but can be implemented in various different forms, and the embodiments are provided only to make the disclosure of the present application complete, and to completely inform those skilled in the art to which the present application belongs of the scope of the present application, the present application being limited only by the scope of the claims. In addition, throughout the specification, the same reference numerals refer to the same elements.

[0034] In general, an exercise bike has a handle 1 for supporting the upper body to be pedaled by a user, a bracket 2 to which the handle is attached, a ground bracket 4 installed on the ground, an adjustment rod 5 installed on the ground bracket at a predetermined interval from the bracket, a pedal 6 combined with the bracket, a height adjustment rod 7 inserted into the adjustment rod 5 to adjust the height corresponding to the user's body, and a seat member 8 on which the user sits and then presses the pedal 6 with the lower body to perform a sitting exercise.

[0035] It is known that a user of 50 kg consumes 184 kcal of heat by exercising on the above-described exercise bike for 30 minutes. When exercising on such an exercise bike, it is possible to reduce weight and decompose fat in the body, exercise lower body muscles, prevent joint diseases, prevent migraine, and prevent diabetes.

[0036] The above-described effects can be achieved only by long-term regular exercise, but the existing exercise bike has no way to buffer the fluctuations that occur when sitting and exercising, cannot improve the physical functions of users who have potential spinal diseases, and the exercise bike for the purpose of simply training the lower body only causes the development of leg muscles, increases the burden on the spine by exercising in a fixed state during pedaling, and forcibly blocks the maximum movement of the hip joint.

[0037] Therefore, the present application was made to improve the overall problems of the exercise bike, which has a lower practical value than other existing devices, when the user sits on the seat of the exercise bike and pedals, induces the left and right swinging of the seat and the buffering effect of dispersing the load, enables the user to directly adjust the range of motion of the hip joint, and ensures the stability of the movement of the pelvis and the spine when pedaling, and the rotation structure of the seat of the exercise bike, which enables core muscle training while exercising the lower body when pedaling, especially directly adjusts the range of motion of the hip joint.

[0038] Hereinafter, the configuration of the present application, its effects, and the effects thereof will be uniformly described with reference to the accompanying drawings.

[0039] As shown in the drawings, Figure 1 the present application has a buffer part 100 provided on the bottom surface of the seat member 8 to reduce the load dispersed by the pedaling action of the user and the left and right fluctuations, a left and right moving part 200 combined with the buffer part to perform left and right sliding operations, a forward and backward moving part 300 combined with the left and right moving part 200 to perform forward / backward sliding operations, and an eccentric rotating part 400 connected to the left and right moving part 200 and the forward and backward moving part 300 and simultaneously controlling the sliding operations of each moving part by eccentric rotation.

[0040] In particular, the eccentric rotating radius of the eccentric rotating part 400 can be enlarged or reduced according to the user's selection, and the left and right sliding and forward and backward sliding operations are controlled by the adjusted rotating radius.

[0041] That is, the eccentric rotating part 400 has a fixing plate 410 that surrounds the outer circumferential surface of the height adjustment rod 7 and is kept in place, a rotating connection part 420 that extends from the fixing plate and is provided with a protrusion that protrudes upward from a set position, and a rotating control part 430 that is configured to be combined with the protrusion 422 of the rotating connection part 420 and to be able to expand or reduce the radius of rotation while eccentrically rotating in a state of keeping the combination.

[0042] The rotating control part 430 includes a main body 431 connected to the rotating connection part 420 and having a hollow area formed by a set distance, a medium-length bolt 432 longitudinally passing through the center of the main body, a grip part 433 that guides the user's grip by protruding or protruding left and right from the end of the medium-length bolt or forming a key in a key groove, and a position adjustment part 434 provided in the hollow area of the main body, fixed to the medium-length bolt, and changing the position in the hollow area of the main body by operating the grip part to rotate the medium-length bolt by threads, thereby adjusting the radius of rotation.

[0043] When the user adjusts the radius of rotation to match the user's body, the radius of rotation will be the range of motion of the user's hip joint. That is, the user can adjust the radius of rotation several times before pedaling the exercise bike to adapt to the range of motion of the hip joint, so that the left-right moving part 200 and the front-back moving part 300 cooperate with each other to perform linear reciprocating motion. In this way, the user directly adjusts the range of motion suitable for his own spine shape, thereby ensuring the stability of the spine, and in some cases, the core muscle training can be induced by setting the radius of rotation matching the maximum range of motion of the hip joint.

[0044] To this end, the present application includes the following configuration.

[0045] In detail, as shown in Figures 2-3 The buffer part 100 includes a buffer plate 110 combined with the upper part of the left-right moving part having a downwardly inclined cross section, having a radius of rotation, and a coil part 120 consisting of two groups combined to both sides of the bottom surface of the buffer plate to cause the left-right swing of the saddle and the buffering effect of dispersing the load.

[0046] The buffer plate 110 has a downwardly inclined cross section, and when the user sits on the saddle, the upper body naturally protrudes forward, thereby preventing the imbalance of the upper body load on the spine, ensuring the stability of the body during long pedaling, and allowing the user to focus on the hip joint and pelvic movement. In a normal exercise bike, the angle of the knee and foot should be between 10° and 15° when the pedal is pressed to the maximum, accordingly, when the user places the saddle at a height corresponding to the length of the leg by the height adjustment rod 7, the use flexibility of the hip joint is ensured by matching the angle of the upper body to the angle.

[0047] The coil portion 120 is composed of a spring coil to generate a buffering effect. The effective number of turns of the coil is freely selectable within a range of buffering a human load, and it is natural that it is not important if the purpose of buffering is achieved.

[0048] At this time, the buffering plate 110 and the coil portion 120 are combined to the upper portion of the left-right moving portion 200, and are combined to the second left-right connecting portion 230. In detail, the buffering plate 110 can be hingedly coupled to the connecting portion 234. That is, the hinged coupling is performed to provide a predetermined radius of rotation, and when the user swings left and right, the restoring force of the spring coil of the coil portion 120 is applied.

[0049] The left-right moving portion 200 has a left-right block 210 connected to one side of the eccentric rotating portion 400 and fixed to the position, a left-right moving portion 220 for guiding the left-right block to slide by standing on the left-right block 210, and a second left-right connecting portion 230 connected to the left-right moving portion 220, having a buffering portion on one side and having a front-rear moving portion on the other side.

[0050] The left-right block 210 performs linear reciprocating motion on the left-right moving portion 220.

[0051] The left-right moving portion 220 is formed in a linear shape and is installed upward on the left-right block 210 connected to the fixing plate 410 to perform linear reciprocating motion on the left-right connecting portion. In particular, the second left-right connecting portion 230 is integrated with the left-right moving portion 220. At this time, the second left-right connecting portion 230 is extended from the left-right moving portion 220, and a hollow space is formed at the boundary of the second left-right connecting portion 230 and the left-right moving portion 220.

[0052] The front-rear moving portion 300 enters the hollow space that is the boundary between the second left-right connecting portion 230 and the left-right moving portion 220 and is combined to one side of the second left-right connecting portion 230, at this time, one side corresponds to the inner surface of the second left-right connecting portion 230. Since the other side will be the outer surface of the second left-right connecting portion 230, the buffering portion 100 is connected to the outer surface, that is, to the upper portion. The second left-right connecting portion 230 can further include a connecting portion 234 hingedly coupled to the buffering portion 100 and having an inclination corresponding to the inclined cross section of the buffering portion. The operation of the connecting portion 234 and the buffering portion 100 is the same as described above.

[0053] The front-rear moving portion 300 includes a front-rear moving portion 310 fixed to the left-right moving portion 200 and providing a front-rear sliding distance, and a front-rear block 320 installed in the front-rear moving portion and performing a front-rear sliding operation of the front-rear moving portion.

[0054] The front-to-back moving portion 310 is formed into a linear shape, fixed to the second left-right connecting portion 230 of the left-to-right moving portion 200, and mounted upwardly on the front-to-back block 320. The lower portion of the front-to-back moving portion 310 stands upright in the front-to-back block 320, and the upper portion is coupled to the inner surface of the second left-to-right connecting portion 230 of the left-to-right moving portion 200. With this structure, the front-to-back moving portion 310 can reciprocate without interference.

[0055] The front-rear block 320 is a structure that connects the front-rear moving portion 310 and the eccentric rotating portion 400, which will be described below, and is in contrast to the left-right block 210 that is connected to one side of the eccentric rotating portion 400. In an overall configuration, the front-rear moving portion 310 is mounted upwardly above the front-rear block 320, with the bottom surface of the block connected to the rotation control portion 430 of the eccentric rotating portion 400. The front-rear block 320 slides back and forth on the front-rear moving portion 310 by the rotational force applied from the rotation control portion.

[0056] The sliding operation of the horizontal moving part 200 and the front-rear moving part 300 is due to the rotation operation of the eccentric rotating part 400 as a feature of the present invention, and the distance of the reciprocating motion is also due to the expansion or reduction of the rotation radius of the eccentric rotating part 400.

[0057] In the following, reference will be made to Figures 4-5 The eccentric rotating portion 400 , which is a feature of the present invention and is used to control the left-right moving portion 200 and the front-back moving portion 300 , will be described.

[0058] First, the overall operation of the present invention is that when a user sits on the seat and pedals with their lower body, the left-right moving portion 200 and the front-back moving portion 300 operate in response to the movement of the hip joint and changes in pelvic position, as the eccentric rotating portion 400 rotates. At this time, the cushioning portion 100 acts as a collective action to cushion the load selectively applied to the left and right pelvises in response to pedaling.

[0059] In particular, through the structure of the eccentric rotating part 400, the user can adjust the rotation radius in direct response to the movement of the hip joint and the variable position of the pelvis during pedaling, thereby reducing the burden on the spine and maintaining body balance.

[0060] To this end, the eccentric rotating part 400 includes a fixing plate 410 surrounding the outer circumferential surface of the height adjustment rod 7 and maintained in place, a rotating connection part 420 extending from the fixing plate and provided with a protrusion 422 protruding upward from a set position, and a rotating control part 430 configured to be combined with the protrusion 422 of the rotating connection part 420 and capable of expanding or reducing the eccentric rotating radius while eccentrically rotating in a state of maintaining the combination, the rotating control part 430 including a main body 431 connected to the rotating connection part 420 and having a hollow area formed by a set distance, a medium-length bolt 432 longitudinally passing through the center of the main body, a gripping part 433 left and right rotatingly guiding the user's grip by protruding or protruding left and right from the end of the medium-length bolt or forming a key in a key groove, and a position adjustment part 434 provided in the hollow area of the main body, fixed to the medium-length bolt, and changing the position in the hollow area of the main body by threadedly rotating the medium-length bolt by operating the gripping part.

[0061] In detail, the rotating control part 430 includes various embodiments.

[0062] The rotating control part 430 is manufactured to have different lengths. The purpose is to take the average of the user's body characteristics, or to selectively assemble according to gender differences, i.e., the width value of the pelvis.

[0063] That is, the change in the length of the rotating control part 430 itself means that the combined distance between the protrusion 422 and the front and rear blocks 320, i.e., the distance therebetween, changes, for example, as the length of the rotating part is longer, the eccentric rotating radius expands as the distance between the protrusion and the front and rear blocks widens, and, conversely, as the length of the rotating part is shorter, the rotating radius decreases as the distance between the protrusion and the front and rear blocks narrows.

[0064] As described above, by processing the rotating control part 430 having a longer length and the rotating control part having a shorter length, selective assembly can be performed according to the user's physical condition, or the rotating part 430 itself can be adjusted in detail in length, thereby providing a general structure for improving stability, usability, convenience, etc. Alternatively, one end of the rotating part 430 of the present application is provided with a hole for rotating connection with the protrusion 422. At this time, a plurality of holes are arranged at intervals, and the user can select any one of the plurality of holes according to his or her physical condition and engage the protrusion 422 to achieve adjustment of the eccentric rotating radius of the saddle. For example, as the protrusion 422 is fastened into the hole formed at a position close to the front and rear blocks 320, the eccentric rotating radius of the saddle is reduced.

[0065] Preferably, the rotation control part 430 of the present application includes a main body 431 constituting a rotation part, a center control area being formed in the center part, a medium long bolt 432 longitudinally passing through the center of the main body, a holding part 433 rotating left and right to guide the user's grip by protruding or protruding left and right from the end of the medium long bolt or forming a key in the key groove, and a position adjusting part 434 provided in the hollow area of the main body, fixed to the medium long bolt, and changing the position in the hollow area of the main body by operating the holding part to rotate the medium long bolt by the thread.

[0066] As Figure 5 shown, the user rotates the medium long bolt 432 clockwise or counterclockwise using the holding part 433, changes the position of the position adjusting part 434, and thus adjusts the eccentric rotation radius of the saddle.

[0067] For example, the eccentric rotation radius of the saddle increases as the position of the position adjusting part 434 is away from the protrusion 422, and the eccentric rotation radius of the saddle decreases as the position of the position adjusting part approaches the protrusion. Therefore, using the rotation and sliding principle of the medium long bolt 432 and the position adjusting part 434, the eccentric rotation radius of the saddle can be easily changed according to the user's physical condition.

[0068] In addition, Figures 4-5 the adjustment method of the eccentric rotation radius of the saddle shown is only related to one embodiment of the present application, and is not limited thereto, and this configuration is implemented to adjust the rotation radius, and thus any one can be selected as long as the purpose is achieved.

[0069] If the rotation radius can be adjusted in this way, the user can select a rotation radius suitable for his or her body, and thus has the advantages of improving stability and ensuring simplicity and convenience of operation.

[0070] Hereinafter, the operation of the present application will be described based on the above-described structure of the present application with reference to Figures 6-8

[0071] As Figures 6-7 shown, the user controls the rotation radius of the eccentric rotation part 400 by manipulating the holding part 433 of the rotation control part 430 before or at the same time as pedaling, and the adjustment operation is the time of the rotation radius corresponding to the range of motion of the user's hip joint and the flexibility of the spine. In this state, when the user sits on the saddle member 8 and applies a load for pedaling, the front and rear blocks 310

[0072] The distance provided by the front and rear moving part 320 performs a straight reciprocating motion forward and backward, and at the same time, the left and right blocks 210 slide left and right on the left and right moving part 220, i.e., perform a straight reciprocating motion.

[0073] ​When the hip joint is at the maximum point on both sides as the left and right moving part 220 reciprocates, the body naturally tightens the core muscles such as the abdominal oblique muscle to maintain balance, so the core muscles will be strengthened by the exercise of the exercise bike.

[0074] In addition, as Figure 8 indicated, in the state that the buffer plate 110 is combined with the second left and right connecting part 230, a predetermined radius of rotation is provided to actively adapt to left and right fluctuations, and in order to compensate for this, the coil part 120 applies a restoring force, and overall, the compensation of the movement of the left and right moving part 200 and the front and rear moving part 300 is performed in the buffer part 100, so there is a further reduction in the burden applied to the user's spine.

[0075] Therefore, the exercise bike is a widely used device that can exercise at home without having to go to a gym to exercise the body. As described above, the exercise bike can have a variety of beneficial effects on the body, and in particular, it can exercise the lower limb muscles, consuming calories when continuously for more than 30 minutes. In addition to burning body fat, which is a common effect of aerobic exercise, in terms of physical training, the effect is negligible.

[0076] On the other hand, in order to increase the negligible effect, it is necessary to exercise on the exercise bike for a long time, and for modern people who are accustomed to a sedentary lifestyle and have underlying diseases, it has a harmful effect rather than a beneficial effect. For example, the burden on the back increases due to long periods of sitting. This is due to the limitations of sitting exercises that fix the upper body and only concentrate on the lower body muscles.

[0077] Therefore, the present application is characterized in that it reduces the burden on the waist, eliminates the above-mentioned limitations even in long-term exercise, and provides a significant improvement effect, for example, by adjusting the movement point corresponding to the user's own hip joint range of motion and spinal flexibility through the rotation control part 430, the buffer part 100 acts as compensation for the linear reciprocating motion of the left and right moving part 200 and the front and rear moving part 300.

[0078] In particular, through the structure of the rotation control part 430, the user can set a pedaling environment suitable for their own physical condition, provide a sliding motion, and thus improve stability and operability.

[0079] In some cases, the user can induce core muscle training by providing the maximum radius of rotation by manipulating the rotation control part 430 within the user's maximum hip joint range of motion.

[0080] The application described above with reference to one embodiment is illustrated by way of example only in the accompanying drawings and various modifications and other embodiments can be apparent to those skilled in the art in view of the foregoing description. Therefore, the true scope of the application is to be indicated by the appended claims, and all changes which come within the meaning and range of equivalents are intended to be embraced therein.
