Spatial relationship.

Referring to Figures 1 to 3, a specific configuration of a stair machine 10 is illustrated. A transmission unit 40 (shown in Figure 4) is mounted on a frame 20, and the transmission unit 40 is controlled by a control system ( Operation (not shown) can drive a stair device 30 to circulate in the frame 20.

The frame body 20 has a base 22 and a plurality of uprights 24. The uprights 24 are welded to the two sides of the base 22, and at least one crossbar 26 is welded between the two uprights 24, except that the fastening side is used for the transmission device 40. In addition to the adjustment plate 21, the structural strength of the frame 20 can be enhanced to collectively support a diagonal bracket 28 above the base 22.

The oblique bracket 28 has a certain angle, and has a high end and a low end. The high end of the diagonal bracket 28 is fastened to a frame 12, and the required control system (not shown) can be disposed in the frame 12, such as a programmable processor, a memory (or memory), a timer, an input/ Output equipment and other control equipment. The lower end of the diagonal bracket 28 is fastened to the two pillars 14, and the pillars 14 cooperate with the frame 12 to support the two poles 16 and the two grips 18 on both sides of the frame body 20. Specifically, one end of each of the stays 16 is secured to the side of the frame 12 and the other end is fastened to the top of the corresponding uprights 14. When the stair machine 10 is in motion, a user can hold the lever 16 or the grip 18 to avoid an accident of falling.

The stair device 30 is comprised of a number of steps 32. In this embodiment, each step 32 has a pedal 34 and a baffle 36. The opposite ends of the pedal 34 and the baffle 36 are pivotally connected to each other. The pedal 34 is pivotally connected to the free end of the baffle 36, respectively. The steps 32 are such that all of the steps 32 are connected into a stair device 30 that can be circulated. As for the detailed structure of the stair equipment 30, please refer to the US Patent No. 9216317, which is not described here.

In Figures 1 and 4, the transmission 40 includes a sprocket set and two chains 48 for urging the stair apparatus 30 to circulate in the frame 20. The sprocket set is composed of two central shafts 42, two first sprocket wheels 44 and two second sprocket wheels 46. One of the two central shafts 42 is disposed at a portion of the frame body 20 near the high end of the oblique bracket 28, and the two ends thereof are respectively connected to the first sprocket 44. The remaining central shaft 42 is disposed at the lower end of the frame body 20 adjacent to the oblique bracket 28, and the two ends thereof are respectively connected to the second sprocket 46. Each chain 48 engages the first and second sprockets 44, 46 to provide the force required for the stair device 30 to circulate in the frame 20.

The transmission 40 also has a motor 50, a drive belt 51, a force wheel 53, a drive wheel 56 and a driven wheel 58. Wherein, the driving wheel 56 is combined with an output shaft 54 that receives the torque of the motor 50 and converts into the kinetic energy of the rotation of the driving wheel 56. The driven wheel 58 is sleeved on the central shaft 42 and maintains a rotationally coupled coupling relationship with the first sprocket 44. The drive belt 51 surrounds the periphery of the active and driven wheels 56, 58 and transmits the torque of the motor 50 to the first and second sprocket wheels 44, 46, acting as a source of circulatory motion for the stair apparatus 30.

Next, referring to Figs. 1 and 5, the tension pulley 53 is disposed outside the adjustable plate 21 by a movable shaft 23. The movable shaft 23 is displaced upwards 25 or downward 27 along the arrow of FIG. 5, and the tension pulley 53 is displaced in the same direction with respect to the adjustable plate 21, thereby changing the tension value of the transmission belt 51, facilitating the transmission of the active and driven wheels 56 and 58. The required force.

It is not difficult to understand from Fig. 6, the motor 50 is provided with an electric brake 60 and a fan 61, and a shifting mechanism 70 is additionally mounted. The motor 50 has a motor shaft 52 (or a rotor), and the electric brake 60 and the shifting mechanism 70 are coupled to the motor shaft 52 at both ends. The fan 61 is electrically connected to the control system (not shown) to exclude thermal energy generated by the motor 50 or the electric brake 60 during energization.

As shown in Fig. 7, the electric brake has a fixing plate 62 which is locked to a guide 63. The guide 63 is fastened to the motor 50, except that a guide is arranged between the guide 63 and the fixed plate 62. In addition to the sheet 64 and an armature plate 66, one or more coils 68 are disposed inside the guide 63.

Upon energization, the coil 68 generates a magnetic reaction that attracts the armature plate 66 to the direction of the guide 63, thereby releasing the sheet 64, allowing the motor shaft 52 to freely move.

The coil 68 has no magnetic reaction during or after powering down, and naturally cannot hold the armature plate 66. The armature plate 66 is pushed back by other forces, such as the spring force of the spring, and can be pressed or bitten to cause the piece 64 to prevent rotation of the motor shaft 52, producing the desired braking effect.

In Figs. 6, 8, and 9, the motor 50 has a motor cover 55, and a shaft hole 57 is formed in the center of the motor cover 55, and three mounting portions 59 are provided beside the shaft hole 57. As such, one end of the motor shaft 52 passes through the shaft hole 57 and allows the output shaft 54 to pass through a bearing 78 and is disposed in one of the three mounting portions 59.

The shifting mechanism 70 includes a first transmission gear 72, a second transmission gear 74 and a third transmission gear 76. The first transmission gear 72 engages the end of the motor shaft 52 exposed to the shaft hole 57. The second transmission gear 74 and the first transmission gear 72 are disposed on the same mounting portion 59, and both have a certain gear ratio. The third transfer gear 76 is sleeved on the output shaft 54 in maintaining meshing relationship with the second transfer gear 74. Therefore, the motor shaft 52 drives the output shaft 54 to rotate via the shifting mechanism 70 while the motor shaft 52 and the output shaft 54 have different rotational speeds.
