Description

Sports Equipment

This creation relates to the resistance technology of fitness, in particular to a sports equipment, which has a plurality of block systems of the same structure but different resistance.

As we all know, there are many kinds of sports equipment. From the point of view of the exercise function, it is roughly classified into a treadmill, a rowing machine, an elliptical machine, etc.; in terms of structure, it can be divided into an electric type and a non-electric type.

For example, the stepper disclosed in Taiwan Patent No. 448063 adopts a non-electric structure to achieve the exercise effect of walking and running. The stepper has a belt and a belt, the belt sleeve is circulated in the two rollers, the brake belt has frictional resistance to one of the two rollers, and the belt has a deceleration braking effect. However, a single friction force cannot achieve a fine adjustment function.

Moreover, the treadmill of the US Patent No. 2014/0274578 A1 replaces the friction structure with a magnetoresistive structure. The magnetoresistive structure is composed of a flywheel and a permanent magnet. The flywheel is disposed in one of the two rollers and rotates in the same direction. The permanent magnet faces the outer circumferential surface of the flywheel to generate an Eddy Current effect, which enables The flywheel decelerates. Although the magnetoresistive structure can achieve fine adjustment performance, the resistance value is low, and high resistance like a friction structure cannot be produced.

Thus, the sports equipment of the Taiwan Patent No. I593444 proposes a comprehensive resistance structure consisting of a brake belt, a flywheel, a permanent magnet and a metal disc. Wherein, the flywheel is still disposed on the drum and rotates in the same direction, and the high friction is obtained by rubbing the outer circumferential surface of the flywheel with the brake belt; the metal disc is coupled with the flywheel to rotate together, and the permanent magnet is brought close to the side of the metal disc to obtain low resistance.

In view of this, this creation provides a new generation of sports equipment, the main purpose of which is to adopt a new type of retardation system, which is composed of a plurality of identical structures, which have different resistance strengths, and can solve the drawback that the frictional resistance cannot be adjusted, or Let the magnetoresistive structure get a higher resistance value.

Due to the above object, the sports equipment of the present invention comprises: an exercise unit having a rotating portion; a transmission mechanism connected to the rotating portion, the transmission mechanism outputting rotational kinetic energy of the rotating portion; and a blocking system, The transmission mechanism is connected. The retardation system is composed of a plurality of resistance structures. The resistance structures are the same, but have different resistances. The transmission mechanism generates the rotation kinetic energy of the rotating portion by all or one of the resistance structures to generate the exercise unit. Slow down effect.

Simply put, the block system of the creative sports equipment can be composed of multiple friction structures. These friction structures are the same, but have different resistance values, which naturally facilitates the adjustment of various frictional resistances. Alternatively, the retardation system is comprised of a plurality of identical magnetoresistive structures having different resistance values sufficient to select a higher strength resistance value than the individual magnetoresistive structures to reduce rotational speed and exercise.

In order to make the above objects, features, and advantages of the present invention more comprehensible, one or more preferred embodiments are described in detail with the accompanying drawings.

Figure 1 is a schematic diagram of the creation of sports equipment.

Figures 2 to 7 and 9 are top views of the first to seventh embodiments in which the transmission mechanism cooperates with the retarding system.

Fig. 8 is a cross-sectional view taken along line A-A of Fig. 7.

In Figures 1 and 2, a treadmill is implemented as the sports equipment 10 of the present creation. In some embodiments, a rowing machine, an elliptical machine, or other fitness equipment having a rotating configuration can be used as the sports equipment 10 of the present invention.

The treadmill has an exercise unit 12 composed of a frame body 11, two rollers 13 and a running belt 15. Among them, these rollers 13 are provided at the front and rear ends of the frame body 11, and each of the rollers 13 is kept freely rotated with respect to the frame body 11. The running belt 15 is sleeved on the two rollers 13 and maintains a frictional relationship with the drum 13. Therefore, the running belt 15 is circulated by a force (generally referred to as kinetic energy of a user's movement), and the associated drum 13 is rotated on the frame 11.

The treadmill also has a transmission mechanism 20 that is coupled to a retarding system 30 to form a first embodiment that is commonly disposed in front of the frame body 11. In the present embodiment, the drum 13 defining the front of the frame body 11 is a rotating portion 14, which is closer to the damping system 30 than the drum 13 at the rear end of the frame body 11, which is advantageous for the kinetic energy of the running motion of the running belt 15. Output to the transmission mechanism 20. In some embodiments, the drum 13 at the rear end of the frame 11 is regarded as the rotating portion 14 for connecting the transmission mechanism 20 and the retarding system 30, which is also an allowable range of the present invention.

Specifically, the transmission mechanism 20 is composed of a flywheel 21, a driving wheel 22, a first transmission belt 23, a driven wheel 24, a last wheel 25 and a second transmission belt 26. The flywheel 21 is connected to the rotating portion (that is, the drum 13 in front of the frame), and can be synchronized with the running belt 15. The first transmission belt 23 is sleeved on the outer circumferential surface of the flywheel 21 and the driving wheel 22. The passive wheel 24 and the driving wheel 22 maintain coaxial rotation, and the second transmission belt 26 covers the last wheel 25 and the driven wheel 24. Therefore, the transmission mechanism 20 is erected on the treadmill and is capable of transmitting the energy of the circulatory movement of the running belt 15.

In terms of rotational speed, it is assumed that the diameter ratio of the flywheel 21 and the driving wheel 22 is 3:1, and the ratio of the diameter of the driven wheel 24 to the last wheel 25 is about 3:1. Since the rotational speed is inversely proportional to the diameter, the rotational speed ratio of the flywheel 21 to the drive wheel 22 is approximately 1:3, and the rotational speed ratio of the driven wheel 24 and the final wheel 25 is also maintained at a ratio of 1:3. The flywheel 21 and the last wheel 25 are under the condition that the number of revolutions of the driving wheel 22 and the driven wheel 24 are the same. The speed ratio is about 1:9.

The retarding system 30 is composed of a plurality of resistance structures, which are identical but have different resistances, and the rotational kinetic energy of the rotating portion 14 is counterbalanced by the transmission mechanism 20 in all or one of the resistance structures, and the exercise unit is 12 produces a deceleration effect.

In the present embodiment, these resistance structures are defined as a first magnetic damper 31 and a second magnetic damper 36, and the configurations of these magnetic dampers 31, 36 are substantially the same.

As seen in the first magnetic damper 31, it has a metal disk 32, a plurality of magnetic members 33, and a yaw arm 34. The metal disk 32 maintains a coaxial coupling relationship with the drive wheel 22 (or the driven wheel 24) and is capable of rotating synchronously with the drum 13 (or the running belt 15). These magnetic members 33 are bonded to the yaw arm 34 toward each other, and are close to the side of the metal disk 32 as a normal state. The yaw arm 34 is disposed on the treadmill to reciprocate relative to the metal disk 32. It is coupled to a connecting cable 35A that urges the yaw arm 34 away from the metal disk 32 and the magnetic member 33 away from the metal disk 32. The side.

Similarly, the second magnetic damper 36 is composed of a metal disk 37, a plurality of magnetic members 38, and a yaw arm 39. The difference is that the metal disc 37 maintains a coaxial coupling relationship with the last wheel 25, so that the metal disc 37 rotates faster than the metal disc 32.

Furthermore, another connecting cable 35B is coupled to the yaw arm 39 sufficient to operate the yaw arm 39 to control the distance of the magnetic member 38 from the metal disk 37.

These yaw arms 34, 39 can be brought close to the respective metal discs 32, 37 alone or simultaneously during use. Moreover, the eddy current resistance of the first magnetic damper 31 to the metal disk 32 by the magnetic member 33 is smaller than the eddy current resistance of the second magnetic damper 36 caused by the magnetic member 38 to the metal disk 37.

The eddy current resistance of the first magnetic damper 31 herein refers to a resistance phenomenon in which the rotational speed of the metal disk 32 is slowed down when the magnetic fields of the rotating metal disk 32 and the magnetic member 33 intersect. If the magnetic member 33 applies a force of 1 KG to the metal disk 32 (ie, resistance), in the main The driving wheel 22 generates a resistance of about 3 KG to the driving wheel 22 under the condition that the distance from the metal disk 32 to the axis is about 1:3.

In terms of the second magnetic damper 36, it is assumed that the magnetic member 38 also applies a force of 1 KG to the metal disk 38, and the distance between the last wheel 25 and the metal disk 38 to the axis is about 1:3, so that the last wheel 25 is obtained. A resistance of about 3KG. Output to the first magnetic damper 31 via the transmission mechanism 20, the eddy current resistance of the second magnetic damper 36 is amplified by a factor of three, so that the driving wheel 22 obtains a resistance of about 9 KG.

Briefly, whether the first magnetic damper 31 alone is selected to counter the rotational kinetic energy of the rotating portion 14; or, the second magnetic damper 36 alone counters the rotational kinetic energy of the rotating portion 14; or, the first and second magnetic damping The devices 31 and 36 collectively counteract the rotational kinetic energy of the rotating portion 14, and both of them can cause the exercise unit 12 to produce a deceleration effect.

In the first option, the kinetic energy of the rotating portion 14 is countered by the resistance of 3KG; in the second option, the kinetic energy of the rotating portion 14 is counterbalanced with the resistance of 9KG; in the third option, the resistance is equalized with the total resistance of 12KG. The kinetic energy of the rotating portion 14 even causes the running belt 15 to drive the drum 13 to rotate slowly.

Further, the volume of the first magnetic member 33 is smaller than the volume of the second magnetic member 38, and each of the magnetic members 33, 38 is a permanent magnet. Even if the first and second magnetic dampers 31, 36 have the same structure, different resistance strengths can be produced.

Fig. 3 is a second embodiment, which is still composed of a transmission mechanism 20 with a retarding system, and its configuration has the following difference from the first embodiment: since the transmission mechanism 20 has no passive wheel, a last wheel and a second belt, the first The second magnetic dampers 31, 36 maintain a coaxial coupling relationship with the driving wheels 22.

At this time, the volume of the first magnetic member 33 is smaller than the volume of the second magnetic member 38, so the eddy current resistance of the first magnetic damper 31 is different from the eddy current resistance of the second magnetic damper 36.

Figure 4 is a third embodiment, which is also composed of a transmission mechanism 20 and a retarding system. The configuration is substantially the same as that of the second embodiment. The difference is that, firstly, only a single piece of metal disk 32A is rotatably connected to The drive wheel 22 of the transmission mechanism 20.

Next, the plurality of first magnetic members 33A are coupled to each other at a first swing arm 34A as a first group. The first swing arm 34A is operated by the connecting cable 35A to determine the distance between the first magnetic member 33A and the edge of the metal disk 32A.

In addition, the plurality of second magnetic members 38A are coupled to each other to a second swing arm 39A as a second group. The second swing arm 39A is operated by the connecting cable 35B, and the second magnetic member 38A is coupled to reciprocate against the edge of the metal disk 32A.

Of course, the volume of the first magnetic member 33A is smaller than the volume of the second magnetic member 38A, both of which are permanent magnets. Therefore, the eddy current resistance of the first group is less than the eddy current resistance of the second group.

Fig. 5 is a fourth embodiment, which is still composed of a transmission mechanism 20 in cooperation with a retarding system, and its configuration is substantially the same as that of the first embodiment, with the following differences: The transmission mechanism 20 is arranged side by side with the last wheel 25 on the side of the driving wheel 22 (or the driven wheel 24), and has a transmission rod 26A, a left wheel 27, a right wheel 28 and a third belt 29. The transmission rod 26A is rotatably mounted on the treadmill, and the left end 27 and the right wheel 28 are respectively disposed at the two ends. The second belt 26 is used to cover the driven wheel 24 and the left wheel 27, and the third belt 29 is used to cover the last wheel 25 and the right wheel 28.

Although the configurations of the first magnetic damper 31 and the second magnetic damper 36 are substantially the same, the volumes of the two magnetic members 33, 38 are different, and the distances from the passive wheel 24 and the last wheel 25 to the axis are not uniform, so the first The eddy current resistance of the second magnetic dampers 31, 36 is completely different.

Figure 6 is a fifth embodiment, the configuration consisting of the transmission mechanism 20 and the retarding system is substantially the same as that of the fourth embodiment, the difference being that the diameter ratio of the right wheel 28A and the left wheel 27 is about 2:1, The first and second magnetic dampers 31, 36 are coupled to generate different eddy current resistances.

7 and 8 are sixth embodiment, and the configuration of the transmission mechanism 20 in cooperation with the retarding system is substantially the same as that of the fourth embodiment, the difference being: first, the resistance structures are defined as a first friction damper 40 and a The second friction damper 43, the first and second friction dampers 40, 43 have the same configuration, and are composed of a speed bump 41, 44 and a friction wheel 42, 45, but the two speed bumps 41, 44 The different bandwidths make the resistance values of the two friction dampers 40, 43 inconsistent.

For example, a second friction damper 43 is rotatably coupled to the transmission mechanism 20 (generally referred to as the last wheel). The speed bump 44 is fixed at one end to the exercise equipment 10 (see Fig. 1), and the other end is operable to determine whether the speed bump 44 contacts or leaves the surface of the friction wheel 45.

Specifically, the speed bump 44 is composed of a metal strip body 46 and a wear portion 47. The metal strip 46 is flexible, and its two ends are regarded as a fixed end 46A and a movable end 46B. The fixed end 46A is coupled to the sports equipment 10 (see FIG. 1), and the movable end 46B is connected to the connecting cable 35C. The cable 35C operates the distance between the metal strip 46 and the outer circumferential surface of the friction wheel 45. The wear portion 47 is firmly fixed to the side of the metal strip body 46 facing the friction wheel 45, and can closely contact the outer circumferential surface of the friction wheel 45 to generate frictional force with the metal strip body 46, thereby slowing down the rotational speed of the last wheel and even the transmission mechanism 20.

The speed bump 41 is identical to the configuration of the speed bump 44. However, the speed of the speed bump 41 is narrow, and the contact area formed by the friction wheel 42 is smaller than the area where the speed bump 44 contacts the friction wheel 45. Therefore, the frictional resistance of the first friction damper 40 may be smaller than the frictional resistance of the second friction damper 43.

Figure 9 is a seventh embodiment. The configuration of the transmission mechanism 20 in cooperation with the retarding system is substantially the same as that of the sixth embodiment. The difference is that the transmission mechanism 20 has no passive wheel, transmission rod, left wheel, right wheel, and last wheel. a second drive belt and a third drive belt. Therefore, the friction wheel 42, the friction wheel 45 and the driving wheel 22 maintain a coaxial coupling relationship, and the first and second friction dampers 40, 43 generate resistance separately or simultaneously, and the transmission mechanism 20 is used to counter the kinetic energy of the running belt 15. .
