Description

Stair machine

The present invention relates to sports equipment, and more particularly to a stair machine having a locking mechanism.

In general, the operation of the stair machine is not initiated by the equipment, but by the weight of the user. In other words, when the user climbs the stair machine, the pedal of the stair step mechanism is subjected to the weight load, and the oblique component of the weight load is The transmission will start to operate; the conventional stair machine may also be equipped with a power generation device, a control interface, a flywheel and an ECB (Eddy Current Brake) resistance device connected to the transmission. When the transmission starts to operate, the power generation system starts. Power generation, and then start the control interface, the user can adjust the difficulty of movement by operating the ECB resistance device through the control interface. This type of stair machine can not be stopped regardless of whether it is in use or idle. Once the load is applied to it, the step mechanism will start to slide down, which is less safe for the user, for example, an unfamiliar use of the stair machine. It may be frightened by the stepping mechanism that started to slide when it is boarded; for a user who is used to using the stair machine, it may accidentally exceed its own load during intense exercise, and the step mechanism cannot be stopped urgently. accident.

A mechanical speed control device is disclosed in U.S. Patent No. 4,687,195, which is incorporated herein by reference. The brake shoe, the user can pull the connecting rod to move the brake drum, thereby controlling the contact area between the brake drum and the brake shoe, thereby controlling the rotation difficulty of the transmission shaft of the transmission, and when the brake drum is completely in contact with the brake shoe, the transmission shaft It is impossible to rotate. At this time, even if the user stands on the pedal, the transmission cannot be operated, thereby achieving the effect of locking the stair step mechanism. However, the disadvantage of such a device is that the user may accidentally kick in during the exercise. The connecting rod causes the user to suddenly change the sliding speed of the step mechanism without prior notice, and the device cannot provide the function of emergency stop from high speed, for example, if the stairs are unfamiliar The user of the machine is uncomfortable during exercise, the stair machine disclosed in U.S. Patent No. 4,687,195, whether The user or the person around him cannot take a safe rescue action. If the link is forcibly pulled by the user or the user at a high speed, the user may have a serious accident due to the law of inertia; It is also impossible to fully guarantee that when each user wants to board the stair machine, the step mechanism is fixed and cannot slide.

Based on the above-mentioned problem, an electromagnetic speed control device is disclosed in U.S. Patent No. 4,927,136, which is an electromagnetic resistance mechanism connected to a transmission shaft, and the electromagnetic resistance mechanism has a rotary shaft. The output shaft of the electromagnetic resistance unit is coaxially fixed with the flywheel, and the transmission shaft of the transmission is connected to one end of the rotating shaft by a belt and a plurality of pulleys; when the user wants to end the movement, it is necessary to go up to the upper side of the machine. Control interface and press the stop button on the control interface, the electromagnetic resistance unit will gradually lock the output shaft, and finally make the rotating shaft difficult to rotate, in other words, the transmission can not be operated by limiting the flywheel; however, when the user is in a fierce In the state of motion, in general, the user will run at high speed on the pedal. Once the body is unable to load and cannot force himself to accelerate to a higher speed to overcome the pedal that slides down at a high speed, the user himself has no The ability to touch the control interface and start the stop program of the stair machine. At this time, even if the person wants to extend Hand to start the control lock function on the interface will be because of the height of stair machine and difficult to do, so the United States Patent No. 4,927,136 does not solve the same problem users themselves or others in times of crisis can not rescue.

U.S. Patent No. 4,927,136 also discloses the mounting of a sensing element on a rotating shaft or the installation of a tension sensing element on a belt to determine whether there is a user on the stair machine. If there is no user, the sensing element is returned. The signal is sent to the control system, and the control system controls the electromagnetic resistance unit to lock the output shaft so that the step mechanism is in a locked state, so that the next user can safely board the stair machine. When the user is ready to start the exercise, he needs to board the higher pedal and press the unlock button on the control interface to command the control system to control the electromagnetic resistance unit to release the output shaft, and the pedal will start to slide.

However, neither the conventional or the stair machine disclosed in the aforementioned U.S. patent does not control the attitude of the step mechanism in the stop program, that is, the pedal of the step mechanism relative to the ground at each stop of the same stair machine The postures are randomly changed. If the pedal posture is not appropriate, for example, the lowest level of the pedals in the horizontal level is still a certain height from the ground, which may cause the user on the stair machine not to easily return to the ground, which may also lead to the next Users need to spend a little more effort to get on the stairs, which makes it inconvenient to use.

In view of the above problems, it is a primary object of the present invention to provide a stair machine having a locking device that can provide the user himself or a nearby person to stop the operation of the stair machine when needed.

Another object of the present invention is to provide a stair machine having a step mechanism attitude control function during a stop operation, which can further control the attitude of the step mechanism relative to the ground at the end of the stop program, so that the current user can easily return to the ground. It also makes it easy for the next person to board the stairs.

The drive belt (33) (34) is a chain, and in other possible embodiments, other equivalent parts may be used.

Referring to Figures 4 and 5, the stair device (20) is formed by connecting a plurality of step mechanisms (21). In this embodiment, the number of the step mechanisms (21) is eight, and each step mechanism (21) mainly has a support rod (22), a pedal (23), and a baffle (24), wherein each support rod (22) is fixed between the left and right belts (33) (34) in parallel with the ground And the distance between the support rods (22) is equal, and the end of the pedal (23) adjacent to the baffle (24) is fitted to each other in a horizontal axial direction, and penetrates through a connecting rod (25), the pedal (23) The other end is pivotally connected to a support rod (22) belonging to the same step mechanism (20), and the other end of the baffle (24) is pivoted to a support rod (22) adjacent to the step mechanism (20), wherein each support rod The ends of (22) slightly protrude the left and right transmission belts (33) (34) for pivoting the roller (26), and the left end of the support rod (22) is a sensing portion (53a). When the user climbs the pedal (23) of the step mechanism (21) from the access space (R1), the weight is transmitted to the transmission (30) through the step mechanism (21), and the stair device (20) is driven to start. Swipe down, at this time, use It is necessary to continuously step on the next stepping mechanism (21) that slides down to achieve the effect of simulating the climbing of the stairs. The baffle (24) can prevent the user from being connected and supported by the pedal (23). The foot is not lifted high during exercise and is tripped by the pedal (24) of the next step mechanism (21). In addition, when the step mechanism (21) slides down around the upper side of the first transmission wheel (311) (312), the rollers (26) pivoted at both ends of each support rod (22) simultaneously enter the corresponding guide rails (17). In this way, the running smoothness of the stair device (20) and the support strength of the pedal (23) are improved. It is to be noted that the mechanism of the above-mentioned stair device (20) is only an embodiment of the present embodiment. In other possible embodiments, the stair device can also have the structure disclosed in U.S. Patent No. 5,769,759. The pedal, but not the baffle similar to the present embodiment, but still has a plurality of step mechanisms; it will be apparent that in other possible embodiments, those skilled in the art will be able to vary the various types of stair devices. However, the common point should have a plurality of step mechanisms, and each step mechanism has a pedal for pedaling or its equal structure.

Referring to Figures 2 and 3, the resistance device (40) is disposed on the frame body (10) by a plurality of partitions (18). The resistance device (40) has a flywheel (41) and an electrically controlled resistance mechanism (42). The flywheel (41) is pivotally disposed on the partition (18), and is connected to the first transmission wheel (311) by a plurality of belts (36) and pulleys (35) of different sizes. When the transmission (30) is operated, The flywheel (41) is rotated by the pulleys (35) and the belts (36). In the preferred embodiment, the flywheel (41) is connected by a belt (36) and a pulley (35) to form a three-stage transmission to drive the flywheel. Rotation, however, the arrangement of the belt (36), the pulley (35), the flywheel (41) and the speed ratio relationship are well-known techniques. In other possible embodiments, the speed ratios of different forms and substantially the same spirit can be adopted depending on the demand. The relationship is not described here; in addition, an electronically controlled resistance mechanism (42) is provided on the front and rear sides of the circumference of the flywheel (41), which can be controlled by the control system to control the rotational speed of the flywheel (41) by electromagnetic effect. In a preferred embodiment, the electrically controlled resistance mechanism (42) includes a pair of electromagnets (421) disposed on the front side and the rear side of the flywheel (41), respectively on the right side of each electromagnet (421) There is a fan (422) for dissipating heat during the control of the speed of the flywheel (41); how the electromagnet (421) affects the rotational speed of the flywheel and other equivalent mechanisms of the electromagnet (421) (such as the ECB resistance mechanism) It belongs to the prior art and will not be described here.

Referring to Figure 1, the control interface (61) can display various parameters of the stair machine (1) for the user to view, such as the speed of the stair device (20) SPM (step per minute), exercise time, amount of exercise, etc., when used When the two hands are held by the heartbeat grip (63) provided on the second armrest (15), the control interface (61) can also display the number of heartbeats of the user, and the control interface (61) and the electronically controlled resistance mechanism ( 42) Electrical connection, the user can adjust the resistance on the control interface (61) so that the stair machine (1) can provide suitable exercise intensity. In addition, the control system also has a multimedia interface (62), for example, installed on the control interface ( 61) The upper television allows the user to view the multimedia content while in motion. In the preferred embodiment, the control system further includes the function of unlocking/locking the aforementioned stair device (20), related system configuration and operation mode. Detailed later. In addition, the control system further includes a speed sensing unit (64) disposed on the transmission (30) for providing a signal to the control system, so that the control system can know the speed of the current transmission (30) through calculation. (30) In this embodiment, a rotary encoder is used, which mainly has a code wheel and a light sensor (not shown). This is a conventional technique, and details are not described in detail; the control system can be sensed by speed. The measuring unit (64) and the resistance device (40) automatically adjust the operating speed of the stair device (20), for example, a light weight user and a heavier user can provide the transmission (30) The oblique load is different. If a stair machine does not have the function of automatic adjustment, the above two users will be more difficult to maintain the same speed for movement. If the control system of this embodiment is used, the weight is heavy. The movement may easily cause the stair device to slide down too fast. At this time, the control system can automatically control the resistance device (40), increase the output to slow down the speed, and maintain the speed at a predetermined speed; When the user is exercising Can reduce the resistance means (40) output, so that the speed of sliding down the stairs device is increased to a predetermined speed easier, stairs (1) can thus be stably operated.

As shown in FIG. 3, the locking mechanism (50) is disposed on the partition plate (18), coaxial with the flywheel (41) and electrically connected to the control system, and can be controlled by the control system to lock the flywheel (41) to make the flywheel Unable to rotate, compared to the resistance mechanism (40), which is mainly used in the present embodiment to progressively adjust the rotational speed of the flywheel (41), the main function of the locking mechanism (50) is to completely lock the flywheel (41), The flywheel (41) is rotated. In the embodiment, the locking mechanism (50) is an electromagnetic mechanical brake, comprising a coil unit, a spring, an armature plate, a fixing plate, a brake shoe, and a release handle (51) Wherein, the brake piece is coaxially fixed with the axis of the flywheel (41), and can rotate together with the flywheel (41). When the electromagnetic mechanical brake does not receive power, the coil unit cannot generate an excitation reaction, and the armature plate is only subjected to the spring. The elastic force is pushed and pressed against the fixed plate. At this time, the brake piece is engaged by the armature plate and the fixed plate, thereby fixing the axis of the flywheel (41) and thereby restricting the flywheel (41) from rotating; When the mechanical brake is energized, the coil unit generates an excitation reaction that attracts the armature plate against The spring force and press the spring. At this time, the brake film will be released, and the flywheel (41) will be free to rotate. In addition, if there is maintenance demand, the flywheel (41) must be unlocked when the power is off. The release handle (51) of the electromagnetic mechanical brake device is forcibly released from the armature plate and the fixed plate, so that the brake shoe and the flywheel (41) are freely rotatable; because the above or similar electromagnetic mechanical brake device is a conventional technology and There are many products on the market, which are only briefly explained here, and are not shown in the figure.

As shown in Fig. 4, the triggering member (52) is disposed in the mat (27) of the ground in the access space (R1), and a person (such as a coach) can easily access the mat (27) and trigger the component (52). Electrically connected to the control system, when the triggering component (52) is triggered, the first signal of the control system can be provided. When the control system receives the signal, the first signal is responded to and a stop procedure is started. Finally, the locking mechanism (51) is finally commanded to lock the flywheel (41), and the stair device (20) is prevented from sliding. In this embodiment, the triggering component (52) is a capacitive sensing. The component is disposed in a mat (27) on the ground of the access space (R1), and the capacitive sensing component has a trigger range, and can detect whether an object (such as a human body) is approached within the trigger range, for example, for example When the user or someone else steps directly on the mat (27) or across the mat (27), it can be triggered. It should be particularly noted that in this embodiment, the user cannot unlock the stair device (20) by triggering the triggering element (52). For example, when the locking mechanism (51) does not receive power, that is, the stair machine ( 1) When in the standby state, the stair device (20) is in a locked state. At this time, when a user wants to use the stair machine (1) of the embodiment, whether it is crossing the tread pad (27), or stepping on the tread pad first. (27) Then board the pedal (23) of the stair device (20). Although the triggering element (52) is activated, the signal is sent to the control system, but the user does not have to worry about whether the stair device (20) has been unlocked. The stair device (20) can be unlocked and moved through the unlocking function of the control interface (61); during the movement, if the user has an uncomfortable need to urgently lock the stair device (20), the control interface (61) can be activated by itself. The provided stop program (for example, pressing the STOP button (not shown)) locks the stair device (20), and if it is unable to touch the control interface (61), it can be approached or stepped on by the person (such as the coach) (27). To activate the trigger element (52) to stop the program and lock the stair Set (20); if the user finishes the movement smoothly, the stair device (20) can be locked by the stop program of the start control interface (61), and if it is negligent, the stair device (20) is exited without starting the stop program. When the user steps over or steps on the mat (27), the triggering element (52) sends a signal to inform the control system to stop the procedure, in other words, whether or not the user is aware of the stair device (20) before the end of the exercise, In this embodiment, the stair device (20) can be automatically returned to the locked state, ensuring that each user can step on the fixed pedal (23) when he or she is about to board the stair machine, and prepare for the start. The unlock function starts to move.

One of the inventive spirits of the present invention is that the triggering member is disposed at a predetermined position of the frame body adjacent to the access space and accessible to the user and/or a person, and the predetermined position is not located at a height of the stair machine relative to the ground, but is generally a position where the user's height is accessible, or a place where the normal exercise mode can be easily accessed, for example, the tread pad (27) of the present embodiment, or in other possible embodiments (not shown) The triggering element may be disposed at a position where the first armrest (14) or the second armrest (15) is close to the access space (R1). Such an embodiment allows the user to fail even if the load exceeds the load. The locking function of the control interface (61) is activated close to the control interface (61), and the first armrest (14) or the second armrest (15) can also be easily touched to initiate the stopping procedure; the triggering element (52) may also be located at The side casing of the stair machine (1), the middle section of the first and second armrests (14) (15), etc., may have many options depending on the position of the installable position and may have the inventive spirit as described above. This is not listed one by one.

In this embodiment, the triggering element (52) is disposed in the step (27) of the access space (R1). Normally, when the user wants to board or exit the stair machine (1), the user enters the space (R1) and triggers. The component (52) is provided here to function effectively. In addition, since the triggering component (52) is close to the ground, when an emergency rescue operation is to be performed, the person can conveniently step on the tread pad (27) to activate the triggering component (52). Then stop the stair machine (1) urgently.

It is also possible for the triggering component (52) to use other electronic components that also have a proximity sensing function, such as a resistive, inductive, or optical proximity sensing component, or other sensing function. The device, whether it is a device that changes the parameter inside the sensing element due to the approach of the object, or the sensing element that is triggered by the interruption of the emitted light wave, sound wave, magnetic field, or electromagnetic wave, changes the conduction area, For example, in a possible embodiment, an infrared sensor (active/passive) is disposed at a portion of the first or second armrest near the access space, and the user may trigger infrared sensing when boarding or exiting the stair machine. Of course, the triggering element (52) can also be an electronic component that requires direct contact (eg, pressing) to activate.

Referring to Figure 4, the sensing device (53) is also electrically connected to the control system. When the stair device (20) is in a predetermined posture relative to the frame (10), the sensing device (53) is triggered, whereby In the aforementioned stopping procedure, the sensing device (53) can assist the control system in determining when the locking mechanism (51) can be commanded to lock the stair device (20) for the purpose of stopping the stair device (20) and the pedal (23) can be fixed at It is easy for the user to climb or walk down the angle of the stair machine (1). For example, as shown in Figure 7, a step mechanism is preparing to bypass the left and right second drive wheels, the associated pedal (23) is almost perpendicular to the ground, if the stair device (20) is locked at this time Whether the user wants to go down the stair device (20) or climb the stair device (20), it is necessary to overcome the rather difficult height of the pedal (23) plus the baffle (24); compared to Figure 1. (Refer to Fig. 4), the figure shows the posture of the stair device (20) after the sensing device (53) functions in the stop program, wherein the second and right second transmission wheels are closest to each other. (322) and the pedal (23) above the left and right second transmission wheels (321) (322) is substantially at an angle of 20 degrees with respect to the horizontal plane, at this time, regardless of whether the user wants to board or step down the stairs device (20) ), it is relatively convenient to raise the height of the foot by about half of the height of Figure 7.

As shown in FIG. 4, the sensing device (53) is disposed between the frame body (10) and the stair device (20), and has an inductive component (53b) and the sensing portion (53a), and the sensing component (53b) is in the present invention. In the embodiment, an inductive proximity sensing component (in the field of sensors, or "inductive proximity switch") is an electromagnetic sensing component according to the principle of actuation. The frame body (10) on the left front left side of the left second transmission wheel (321), and the position substantially corresponds to the winding track of the left belt (33), and the sensing portion (53a) is located on the support rod of each step mechanism (21) (22) The left end is connected to the left transmission belt (33). In this embodiment, there are eight sensing portions (53a), and the distance between the sensing portions (53a) is equal. Taking FIG. 4 as an example, a sensing portion ( 53a) as the left belt moves to the position of the sensing unit (53b), the sensing portion (53a) is just obscured by the sensing unit (53b) in the left side view; wherein, in order to match the form of the sensing element (53b), The sensing portion (53a) in this embodiment is composed of a magnetic conductive substance, that is, the left end of the support rod (22) is a magnetic conductive substance, and even a roller (26) Also composed of magnetically conductive substances. When the stair machine is running, the sensing portion (53a) triggers the sensing element (53b) one by one with the operation of the left belt (33), and whenever the sensing portion (53a) enters the sensing range of the sensing element (53b), The sensing element (53b) is triggered and returns a second signal to the control system; once the stopping program starts, for example, the triggering element (52) located in the step (27) is triggered, and when the control system monitors the left and right The first transmission wheel (311) (312) is in a low-speed state, and is calculated according to the signal returned by the sensing element (53) after being triggered, and the speed of the current transmission (30) is calculated at an appropriate time. The point control locking mechanism (51) locks the flywheel (41) to stop the operation of the stair device (20), and when stopped, the step mechanism (21) can be fixed to a predetermined posture as shown in Fig. 1, for example, the present embodiment For example, the attitude of the pedal (23) closest to the ground in the pedal (23) of the general level can be controlled to be within plus or minus 20 degrees of the level when it is determined.

In general, the distance between the pedal and the pedal of most stair machines is the same, and the stair device is composed of a series of step mechanisms. Therefore, as long as the attitude of one of the step mechanisms is controlled, the posture of the entire stair device can be controlled. Therefore, in other possible embodiments, the mounting position of the sensing element may not be the above position shown in this embodiment, and the sensing element may not be electromagnetic, and the number of sensing parts does not necessarily match the number of the step mechanism. One of the sensing elements needs to match the position and nature of the sensing portion, so that each time the sensing portion is triggered to emit a signal, it represents that the stair device at this time is in a predetermined posture, for example, in other possible embodiments. The sensing element may be a light sensing element disposed at an intermediate portion of the second second support rod (133), and the sensing portion may be a light blocking portion added to the step mechanism and having a position and a property matched with the light sensing element. Whenever the step mechanism passes the left second support rod (133), the sensing element is triggered, and each time the sensing element is When triggered, it means that the stair device is in the same predetermined posture; as for the trigger frequency affected by the number of sensing parts, it can be corrected by the setting of the control system. Thereby, the attitude of the step mechanism can be controlled in the stair stop program, so that when the stair machine is stopped, the pedal is at an angle that allows the user to easily enter or exit the stair device.

In addition, in this embodiment, not only the triggering component (52) is disposed at a position that can be easily accessed by others, but also the triggering component (52) is disposed in the mat (27) located on the ground of the access space (R1), such that When the user stops the stair machine (1) through the control interface (61) at the end of the exercise, the user simply exits the stair machine (1) when the movement speed is slow, at this time, as long as the user is from the access space (R1) ) Exiting the stair machine, the stair machine (1) can be automatically locked in the next few seconds with or without stepping on the mat (27), and the attitude control of the step mechanism (21) can be performed during the process, so that the next step The user can easily board the stair machine (1) to start the exercise without the inconvenience of the next user due to the improper operation of the previous user.

Next, referring to Fig. 6, the processing flow of the stop program of the foregoing stair machine (1) in the embodiment is schematically illustrated. In general, in order to balance safety and speed, the stop command is accepted from the control system to the stair machine (1) is stopped and Locked, the entire stop program will be completed in a few seconds. In this embodiment, the operation time of the stop program is about 8 seconds.

In detail, corresponding to step 1 (S1) in the flowchart, whether the user issues a stop command through the control interface (61), or the other person issues a stop command by the trigger component (52), even in In other possible embodiments, a stop command may be issued by the heartbeat grip (63) or the first and second armrests (14) (15), which are considered the same in terms of the angle of the control system, once the stop command is accepted. , that is, the execution of the stop program is started; corresponding to step 2 (S2) in the flowchart, at this time, the control system increases the output of the electronically controlled resistance mechanism (42), and proceeds to step 3 (S3) to continuously transmit the speed sensing. The unit (64) monitors the rotation speed of the transmission device (30) for the purpose of gradually lowering the sliding speed of the step mechanism (21) to below a predetermined speed. In the embodiment, the predetermined speed is the left and right first transmission wheels. The rotation speed is 25 rpm (25 RPM); referring to step 4 (S4) and step 6 (S6), when the rotation speed is lower than the aforementioned predetermined speed, and the control system monitors the stair machine to continue at a lower speed than the reservation Running for a predetermined time (this embodiment is 1 second), at this time, control The system proceeds to step 7 (S7), and the control system starts to refer to the signal fed back by the sensing element (53b), and calculates the control flow to step 8 (S8) at an appropriate time point. At this time, the control system will electrically control the resistance. The output of the mechanism (42) is increased to the maximum, with the aim of gently reducing the sliding speed of the step mechanism (21) to near stop, and simultaneously opening the locking mechanism (51) to lock the flywheel (41), indirectly causing the step mechanism (21) Stopping the slide; due to the completion of step 7 (S7), when step 8 (S8) is completed, the first step pedal (23) for the user will be fixed within 20 degrees of the horizontal; refer to step 9 (S9) ), the electronically controlled resistance mechanism (42) still maintains the maximum output for a predetermined time after the locking mechanism (51) is turned on, in order to avoid the situation that the braking force is insufficient when the locking mechanism (51) first starts to operate, in order to avoid the situation that the braking force is insufficient at the beginning of the locking mechanism (51), For safety and safety, the electronically controlled resistance mechanism (42) and the locking mechanism (51) simultaneously act for the predetermined time. In the present embodiment, the predetermined time is one second; after one second, the program is stopped to the step. 10 (S10), the control system closes the electronically controlled resistance Structure (42); then proceeds to step 11 (S11), to complete the program is stopped.

In addition, if a special situation occurs, for example, the electronically controlled resistance mechanism (42) is faulty, the stop program cannot be lowered to the aforementioned predetermined speed in step 4 (S4). At this time, the stop procedure proceeds to step 5 (S5). In the embodiment, the control system continuously monitors whether the time higher than the predetermined speed is greater than 8 seconds. If the time exceeds 8 seconds, the stopping procedure skips step 6 (S6) and step 7 ( S7), directly perform steps 8 (S8), 9 (S9), 10 (S10), and 11 (S11) to forcibly stop and lock the stair machine (1), although in this special case, the pedal (23) cannot be controlled. Angle, but still ensure that the stair machine (1) provided in this embodiment can be locked. In other possible embodiments, there may be no function of controlling the attitude of the stair device. At this time, the stop program may ignore step 7 (S7) and proceed directly from step 6 (S6) to step 8 (S8).

In a very special case, that is, the user does not start the stop program through the control interface (61), nor does the user exit the stair machine (1) via the access space (R1). Once the user leaves, the stair device (20) does not accept. When the load is reached, the sliding speed will gradually slow down to stop. At this time, the control system is informed by the speed sensing unit (64) that the current speed is zero, and the locking mechanism (51) is locked to lock the flywheel (41). Similarly, In such a very rare example, the angle of the pedal (23) cannot be controlled to a predetermined attitude, but this embodiment still ensures that the stair machine (1) is in a locked state.
