Description

200538184 IX. Description of the invention: [Technical field to which the invention belongs] The present invention relates to a machine which is effectively used for physical exercise. In short, the present invention can be used both as a fitness machine mainly for muscle development and as a machine suitable for racing training, so its main purpose is to develop endurance for long-term running and movement. In detail, the fitness machine of the present invention has at least one device which can be used for repetitive alternating movement along an open trajectory. [Prior art] In the field of fitness machines, there are the following types of machines: machines for performing exercises including / developing muscle parts; exercises for developing multiple muscle parts simultaneously or continuously, and for this purpose "Functional" machines for distribution; and machines that can perform repetitive aerobic / cardiovascular exercises to develop long-term endurance of muscles. Generally, the first machine is equipped with a load section with a weight, of which , The exercise process can produce continuous eccentric and concentric effects, while the second machine is equipped with a load section that can continuously exchange energy with the user while the user is racing Φ. For the latter, the most common is Stationary bicycles are human treadmills for walking or running, so-called "stairs" for simulating paths with steps, and for walking along closed elliptical trajectories on mobile feet and pedals and / Or running elliptical tracker. Stationary bicycles, steppers, and elliptical trackers all have a load section that works by absorbing the energy exerted by the user. Among them, the human treadmill can be started by the user or driven by a starter. The device determines the energy exerted by the user. The step machine is also a type of "floating" type. The energy transmitted to the load during the driving of the pedal can determine the user's center of gravity. 101715.doc 200538184 The racing training machine is particularly suitable for the simulator disclosed in US Patent 5,718,658. According to the specification of the patent, the ice skating simulator can be equipped with two pairs of side-by-side: the arm that rotates along the longitudinal axis; each-the arm drives-uses it as a holding axis and a foot that rotates near a relatively free end point Pedal; each foot-horizontal strip is used to prevent lateral slipping from the foot pedal, thereby inhibiting the movement of the foot. Each lever is operated on the flywheel by means of a mechanical transmission device, which is equipped with There is a belt 'the belt is wound on a live wheel along its path' so as to be linked to the flywheel 'and at its corresponding end point is connected to-the rod and the machine = connection', and the connection is made at that end point by a connection spring. Each lever is braked by a leather belt during rotation, and the lever is returned to the center stop position by the corresponding spring sauce. This kind of machine concept has several disadvantages: First, the user has discomfort, and the user Very moving The two pedals used as pole supports were lifted off the ground; the second 'the user's feet were in the forward direction while the arms were moved from a generally centered stop position to a distal position. Therefore, use Unnatural movement of the naked joint of the person will cause the feet to feel different from the actual skating movement. In the case of a large amount of exercise, this will cause the user to lose balance on the rod, resulting in unforeseen consequences. To make up for some of the above deficiencies, reference can be made to the specification of US Patent Application 200 Lake 42329, in which each foot pedal is supported by an inner curved prism guide on both sides. The shape of the guide rod and the pedal can determine the foot The shape of the trajectory of the pedal can also change the inclination of the user's pedal surface. 101715.doc 200538184. Therefore, the guide rod and pedal pair can increase the clamp between the foot surface and the pedal when advancing the sports towel. Holding force, so as to provide greater safety for the user when each foot moves outwards. The machine load section, which is an embodiment of this application specification, also has a flywheel, which can be provided by a flywheel coaxial with it. In addition, it also has an elastic return device for returning the pedals to a relatively central position. Specifically, the return mechanism also has a flexible material for each pedal, which includes mutual coupling No-belts and-impeachment and circular motion pulleys. However, 'the concept of this invention has several improvements that need to be made if the guide / slider pair is equipped with rotating rollers, which will increase production costs because the guide / slider pair : The production accuracy is high, and it also has significant wear problems, which have a negative impact on the operating cost 'because the guide / slider pair needs to be adjusted frequently. In addition, if its size is directly related to the user's limb length, the structure The absolute rigidity is also to reduce the flexibility of the foot pedal in motion and angle adjustment. It should be noted that due to the above reasons, each foot pedal can move freely in the two inventive concepts, so that each The load part is operated by one foot pedal at a time 'or by two foot pedals at the same time. This is especially suitable for users who are more proficient in skating or muscular and have good balance control.

For the above reasons, the machine concept embodying the specifications of the US patent 5718658 and patent application 0041329 has some improvements, because the type of exercise that can be performed by the person is not a simulation form of skating, and also because it embodies the description of Cha Xi Yao Wu How's said that Jiyi cannot adapt to the body size of users of various heights and also because these machines are bulky, inefficient and costly, and the user department needs a small-scale fitness machine with reasonable cost, and the machine should 101715.doc 200538184 can be used to strengthen muscle strength in skating. [Summary of the Invention] The present invention relates to a machine that can be effectively used for exercise training. "Mao Ming" can be used for fitness machines that are mainly used for muscle training, and also used for racing training, so as to develop long-term endurance. In particular, the fitness machine of the present invention has at least one device which can be used for repetitive alternating movement along the open track. The object of the present invention is to build a fitness machine which can effectively perform the training of simulated skating. Another object of the present invention is to enable the user to obtain the center support # 'when the foot pedal is moved outward, so that the machine can be used indifferently to users who have ever skated and have not skated. Another object of the present invention is to construct a simulated ice skating machine with an external dimension smaller than its motion range 'and a low purchase price and operating cost. According to the present invention, a fitness machine is constructed, the characteristics of which are explained by referring to the request item i and the following. [Embodiment] In Fig. 1, the whole 1 shows a fitness machine having a frame 10 which supports a load section 20 and an exercise station 30 arranged side by side. The station 30 can exchange mechanical energy with the load part 20 and has at least one articulated mechanical component pair 31. The arm 35 is driven by the frame 10 and rotates around the shaft 36, so that it is relatively inclined longitudinally. An appliance cut whose shape can be matched with a specific part of the user's limbs, and is rotatably coupled with the above-mentioned arm 35 at its end point. For example, as can be seen in Figure 2, for security purposes, 101715.doc -10- 200538184

See, the foot pedal has a vertical pole 42 at the opposite center, which can be used as a shock absorber for another foot pedal 40. It can also be used to prevent direct impact between the user's feet and the balance bar, or to prevent Similar problems with interference during use of machine 1. Therefore, the instrument 40 can rotate around its own axis, and can move along a curved and open trajectory P. See FIG. 2, which is indicated by dotted lines and dotted lines. As detailed below, the trajectory P surrounds the axis 36 and bends downward, so that each instrument 40 can start moving from a higher position corresponding to the longitudinal plane L on the centerline of the machine 1 and a lower position on the side. In the following, for convenience, a preferred embodiment will be used to describe the situation of the machine 1 that can be used to simulate skating. However, this choice is not limited to the concept of the present invention which can only be applied to fitness machines that can be used for training in other forms than skating. . As described above, the machine 1 has two counter pieces 31 arranged side by side and on the opposite side of the plane B, which is completely similar to the known machine for simulating skating. As such, in the preferred embodiment, the implement 40 is set as the foot pedal 40. See Figure 2 for plane L.

Also for the sake of convenience, in order to simplify the drawings and the present invention, a device for controlling the machine 1 is not shown. It is a device called a "control console". For details, please refer to the relevant description. In fact, although the console generally has instructions for adjusting machine-specific functions related to the physiological parameters of the user, the description of the device is not included in the concept of the present invention. Each pair of members 31 of the exercise station 30 includes at least one extension member 51 that is longitudinally restricted by the spherical coupling member 52, and connects the material 51 to the frame and the above-mentioned foot pedal 40. Specifically, the ball joint connecting the material 51 to the frame is on the rotation axis 36 side of the arm 35, so the part 51 can limit each pedal 101715.doc -11-200538184 The plate 40 is opposed to each arm 35 Rotating, thereby controlling the rotation of the foot on the surface 41 of the above-mentioned foot pedal 相对 relative to the corresponding arm 35. If it is necessary to make the action of the foot pedal 适于 suitable for the needs of the user, the length of the component 5 丨 can also be adjusted at will. The effect is that 'each user's foot is pushed forward by the foot pedal 40 along the plane L. The stroke and return to the stop position R are matched by the corresponding foot pedal 40. Supported by an open circular trajectory P. Based on the above reasons, even if the corresponding external slope of the trajectory p is downward, the above-mentioned situation g will occur, the purpose of which is to improve the safety of the machine i, thereby protecting uncareful users or insufficiently trained / unskilled users. Based on the above description, each of the foot pedals 40 connects the relevant component 5 丨 with the relevant support arm 35, and the two are rotatably connected to the frame 10. Therefore, the footrest 40 that rotatably connects the arm 35 and each component 51 can function as a lever, and the pair of pieces 31, the combination of the frame 10 and each component 51, and the formation of the hinged square piece 43, A restriction device 50 can be created which controls the rotation of the device relative to the arms 35. The square member 43 restricts the surface 41, φ of the foot pedal 4 so that, under the condition of contact with the surface 41 and being relatively stationary, it will be placed on the foot pedal / rod by a combination of rotation movements around the axis 36. * 〇 Xiangbu's feet lead to the space of follow the synthetic command. Based on the above reasons, each component 51 can generate the combined motion of each pedal 40, including in particular the inward movement of each pedal 40 during the outward movement of the relevant arm 35, and the direction of the pedal 40. Rotate forward, thereby lowering its front portion 44 and raising its rear portion 45. The inward tilt of the foot pedal 40 can slow down the inward bending of the knee, which helps the stability of the pedal joint when it is pushed sideways, and the forward tilt of the foot pedal helps the user's foot in the center position. Center of gravity stability. If the foot pedals 40 remain parallel, the user 101715.doc -12- 200538184 must shift his / her center of gravity during the backward movement, thereby weakening the ability to provide gifts to legs in other positions. This can also keep the feet of each user substantially vertical, and be stationary relative to the upper surface 41 of the foot pedal 40, so as to continuously cooperate with the surface 41. In this way, based on biomechanics, the user can make full use of the motion transmitted by the user to the arm 35, and as a result, the user can achieve the maximum propulsion that can be generated in a fully dynamic equilibrium state. In addition, in this way, you can choose a holding part that can accommodate at least one lateral portion of the foot, so that the structure of each foot pedal can be interspersed and the cost can be reduced. During the exercise, the synthetic movement of the foot pedal 40 can be expressed by the term "valgus movement," because when the leg is held still, the movement is similar to the bending and tumbling movement that the foot can perform. It means' in various In use, when the foot pedal 40 rotates with respect to the axis 36 of the relevant support arm 35, the two light clutches 52 act as couplings at any time and instantly twist each other. Since the volume and functionality of the machine 1 From a viewpoint, if the structure size of the station 30 is small, the layout of the two arms 35 on the longitudinal intermediate plane 1 has a significant advantage φ. In addition, for a certain length of the arms 35, the Compared with its axis 36 on the same side of the plane l, each trajectory p is more significant for the biomechanics of the limbs, especially the joints and feet, below the user. 'In addition, this will be in the legs and feet During the external outward movement, the user can exert more sustained strength, especially in the above-mentioned trajectory P corresponding to the "valgus movement" of the foot. However, it should be recognized that under certain exercise conditions, the arm 35 Specific structure allows Each foot pedal 40 is integrated as one of the axes to drive the same-side of the plane L to adapt to the skating posture of each user. Finally, as shown in FIG. 2, the shapes of the arms 35 are different from each other to Prevent collisions between the arms 35 or between the foot pedals 40 during the movement of the machine 101715.doc -13 · 200538184 1. The arms 35 are each equipped with a stopper 37 The same is true for the arms. It should be recognized that although the track p followed by the pedals needs to be symmetrical with respect to the plane L, if the machine 1 is used to train the lower limbs, which are usually symmetrical, the shapes of the arms 35 must be different from each other In order to prevent possible interference between each other. Therefore, the pair of parts 31 are asymmetrical, and each arm 35 is supported by its own axis 36 ′ on the opposite side and in the opposite plane L from each pedal 40. And can be moved in the space of the area starting from each position of the stop R. It should also be noted that in addition to the circular shape of the foot pedal 40 and the axis 36 as the center, it can also be on a plane There is at least a minimum common length on L. For machine j, the specific geometric configuration of the arm 35 and The orientation of each axis 36 determines that the trajectory P of the foot pedal 40 will intersect at a point geometrically positioned relative to the plane 1. Referring to Figures 1 and 3, the component 20 includes a rotating component 25 having a shape suitable for storing rotational energy, A flywheel 25 is typical, which is supported by a frame 10 through a shaft. The shaft is well-known and is not shown. It is connected to the disk 23 of the electromagnetic brake 24 by a key, which can be continuously consumed and adjusted. In addition, 'the machine 1 is provided with a mechanical transmission 21 between the load part 20 and the exercise station 30', which can convert the alternating rotary motion of each arm 35 into the rotary motion of the flywheel 25. The actuator 21 includes a The idler 27 is connected to the horizontal shaft 38 in the cantilever by a key, and the horizontal shaft is between the two supports shown in FIG. 2 in the frame 10. The idler 27 can rotate in synchronization with the flywheel 25 by a belt 29 and a small shaft 32 coaxial with the flywheel 25. In addition, the actuator 21 includes at least one belt 33 for each arm 35, and each belt 33 is wound on a plurality of pulleys 22. The pulleys are rotatably supported by the frame 10, and the belts are connected in the load section 20 to 101715.doc -14- 200538184 Corresponding arm 35 and free wheel 34. Each wheel 34 can only transmit torque in one direction '. If it is started in the opposite direction, it can only run idly, which is bonded to the shaft 38, so that the kinetic energy is transmitted to the flywheel 25 through the belt 29 of the actuator 21. Therefore, each of the pedals 40 and the corresponding arm 35 can be activated independently of the movement condition or the stop state of other pedals 40. However, as described below, the pedals can also be restricted by using the relevant arm 35 Rotation of the plate 40. It should be noted that the type of the load section 20 can be accompanied by the above-mentioned machine! The type of training performed varies, especially aerobic / cardiovascular or muscle / anaerobic training. Therefore, the component 20 may be an electromagnetic type and may be equipped with a brake 24, as shown in Figures 丨 and 丨 3. For aerobic training, the component 20 may also be a mechanical type, and at least equipped with a belt A weighted device 70 is used for muscle / aerobic training, as shown in Figure 4. In either case, the device 23 and the device 70 can be regarded as a device 60 for controlling the energy transmitted to the pedals 40 by the user. For the sake of simplicity, the detailed description of the brake 24 and the device 70 is omitted. The reason is that, first, the structures of the two devices are known; second, the embodiment of the present invention does not depend on the type selection of the load section. In any case, as shown in FIG. 4, each component 20 is suitable for a mast structure 71 that supports each arm 35 with a component 72 of a weight 73. Each component 72 can be connected to the pedal by a cable 74. The plate 40 is activated vertically. When returning to the skating sport, it should be noted that the skater generally pushes forward when exchanging tadpoles, so each foot will have a pause at the same time. Therefore, in order to effectively generate this movement, a return force can be applied to the center of the non-activated foot pedal 41, so the machine 1 includes a reaction device shown in FIG. 3 and FIG. 5 80, 101715.doc -15 · 200538184 It can exert an inward return on each arm 35 and return each arm "to the center position, thereby acting as a safety device. The intensity of this movement must be selected to be rotated with respect to the outside of each of said arms 35 The angle is proportional. For this reason, the device 80 must have an elastic mechanical characteristic. For this reason, the device 80 can have different embodiments, which generally have at least one acting on the arm 35 by the conveying mechanism 21 According to FIG. 3, the reaction device 80 includes at least a belt 82, which is arranged in an inverted “U” shape between the arms 35 so as to connect them approximately rigidly, and its ends are wound around the shaft 38. The winding direction is opposite to the winding direction of each belt 33 on each pulley 34. Thus, during the movement of the foot pedal 40, when the belt 33 is released from the winding by the tension of the belt 29, the belt 8 2 can be wound on the shaft 38. The belt 82 is continuously pulled by a pulley 83, which is elastically supported by the frame 10 by a bracket 84, which is flapped by a support arm 85, and the support arm 85 The opposite end of the pulley 83 is connected to the frame 10 by a hinge so as to be elastically restricted by the elastic return portion 81. The elastic return portion 81 includes at least a spring 86 connected to the frame 10 through the corresponding end portion. Thus, by reaction The device 80 utilizes each spring 86, and the elastic return force acts on each arm 35. Therefore, after each footboard 40 moves outward, the spring% applies the elastic force to the arm 85 by On other pedals 40, the force is a function of the length of the support arm 85 and the elastic constant of the elastic return portion 81. According to the above description, the device 80 serves as a safety device based on its various types. The user has no training in skating, or the user has not engaged in such sports, and can use the machine without risk. 1. In addition, as can be seen from the above description, 101715.doc -16- 200538184 machine or The ladder machine is similar. In machine 1, the height of gravity can be reduced without the user's movement. For this reason, the frame 10 is equipped with a front part ii whose shape allows the user to climb on or off the machine 1 Lean, or apply bilateral reaction forces to the leg advancement during training. If the spring 86 is equipped with a rigid body 86b that extends longitudinally and is approximately the same as the undeformed spring 86 and is the same as the spring 86 of FIG. 3, then The arm 85 can be prevented from rotating relative to the frame 10, so that each arm 35 can be restricted from rotating with each other, even if the user is unfamiliar with the machine 1. Finally, 'without departing from the scope of the present invention, the description and drawings here can be made. Modifications and changes to the machine 1 shown are obvious. For the sake of clarity, in the description of the above-mentioned machine 1, only the eccentric propulsion movement of each pedal 40 is pushed outward to transfer energy, and in the process of returning the pedal 40 to the center, Inaction, for example, occurs during skating. However, the present invention can also be implemented by a machine that also provides energy for absorption in the process of returning the foot pedal 40 to the center, for example, adding a load part that is substantially the same as the above-mentioned installation but operates Opposite load section 20. For example, if it is considered necessary to match the elastic effect of the device 80 exerted by the above-mentioned components with the characteristics of the user, the device may be modified according to FIG. 5a, and the elastic return portion 81 may be provided with a spring 87 for each arm 35, or According to the illustration, the device 80S & is provided with a spring 87 for each arm 35 and a spring 88 between the arms so as to elastically connect them. In the figure, for the sake of simplicity, the spring 88 is divided into two elastic portions 90, which are opposite to the belt pulley 89 commanded by the frame, but can be operated separately without changing the operation. 101715.doc -17- 200538184 When selecting the type of reaction force according to Figure 3 or Figure 5a or 5b, it should depend on the type of effect that the user believes can meet his / her type of training. The above three different methods should not be understood. To limit the possible embodiments of the reaction device 80, it is merely used to illustrate the possible embodiments of the device 80 described above. According to the above description, it must be noted that in the machine 1, it is not possible to rule out the possibility that the extension members 51 of the arms 35 are also subjected to bending stresses, not just normal to normal stresses. As we all know, when the axis of the hinged square piece is in motion and only under normal stress, the hinged square piece can stably maintain the stability of its vertex trajectory. Only in this state of machine 1, the amount of training or use is less. Users will find the machine comfortable and safe. In order to prevent unforeseen changes in the trajectory of the foot pedal 40, thereby causing potential harm to the user, the machine 1 can be replaced with the machine 1101 shown in Figs. Different similar parts are distinguished, and the reference numbers used differ from those used, unless otherwise specified. Specifically, the machine 101 is equipped with a pair of elbow arms 135, each of which rotates around a shaft 136, and is provided with a restriction device 50 for each linear stroke. The device has a hinge mechanism similar to the hinge square 43 . Referring to FIG. 8, each arm 135 has an elbow 137 and two square pieces 153 and 154, which can be linked with each other, so that the universal lever 157 is used to control the angular position of each foot pedal 14 relative to the arm 135. The rod member 157 is a connecting rod of a square member 154, and is also a crank of a square member 153. The rod member is rotatably driven by a support arm 135 near the corresponding elbow 137. In this article, it can be seen from FIG. 8 that the square piece 153 shares the frame no with the machine, and the frame of the second square piece 154 is provided with each arm 135. In addition, still 101715.doc • 18 · 200538184 Referring to these figures, the square member 153 is provided with an extension member 155 which can be used as a connecting rod, and the square member 154 is provided with an extension member 156 which is used as a balance member. The components 155 and 156 are defined by the spherical connecting members 152 and are similar to the component 51 in that the length can be adjusted to adjust the movement of each of the foot pedals 14 and each of the upper surfaces 141. Similarly, each component 155/156 can produce the combined motion of each pedal 140, especially during the forward movement of the arm 135 and the forward rotation of the pedal 40, which can make each pedal 140 to Tilt inward to lower its front 144 while raising its rear 145. The machine 101 also includes a reaction device 180 which, like the device 80 with reference to the machine description, also functions as a safety device. Referring to FIG. 7, the machine 101 is provided with a mechanical transmission 121 which is located between the load portion 120 and the station 13 and can convert the alternating rotary motion of each arm 135 into the rotation of the flywheel 125. The transmission 121 is similar to the machine 1 and has at least one belt 133 for each arm 135, and each belt 133 is wound on a free wheel 134, which is connected to a belt wheel supported by a frame 110 under the shaft 138 122 is driven by shaft 138. Each wheel 134 is bonded to a shaft 138 next to the flywheel 125, so that the motion torque is transmitted to the flywheel 125, which is mechanically connected to the brake 124 by connecting a coupling 139 having a parallel axis. It can be seen that the difference between machine 1 and machine 1 (H is that the transmission device 21 and the transmission device 121 have first and second-stage parallel shaft couplings respectively. For machine 101, its rotation speed can be greatly increased. The brake 124 'exceeding the brake 24 can thus be controlled more precisely. Referring again to Fig. 7, the reaction device 180 is provided with elasticity for each arm 135 101715.doc -19- 200538184 return member 186, which is used to make the relevant support The arms 135 return to their respective stop positions R. It is best to use a large-diameter torsion spring to activate the components, but it is not limited to this, and the two springs 186 are driven by the frame 11 below the pulley 122 and between the shaft 138 and the brake 124 〇 and coaxial with each other. According to Figure 7, the use of large-diameter torsion springs 186 can help greatly reduce the longitudinal dimension of the machine 101, which has the advantage of enhancing the rigidity and reducing the size of the machine. As a result, The device 180 is smaller than the device 80 of the machine 1. In addition, the device 180 is also provided with an extension member 195, as shown in FIG. 8, which is located between the arms 135 to make them connected to each other, such as As shown in the text, its length is a function of the force applied to the foot pedal 140, resulting in a restraining effect proportional to the angular distance between the two arms 135. Referring to Figure 9, the component ι95 is generally a cushion 8, it is connected to each arm 135 by a hinged end 152. Specifically, the component 195 is provided with a housing 198 which coaxially and freely covers the rod 199, the housing 198 and the rod The piece 199 is connected by a pair of first springs 196 and 197 with different and constant elastic constants. The spring I% has a lower elastic constant, and the springs 196 and 197 are arranged in series with each other, and can be used as an elastic body with a fixed value. When the lever 199 is at the end of the stroke in the housing 198, the damping effect at this point is reduced, and the springs 197 and 196 are coil-wound. Based on the above description, the component 195 mainly uses a lower elastic constant. The spring 196 reacts and is used for a small relative rotation angle between the two arms 35, and the component 195 is reacted only by the spring 197 and is used for a large relative rotation angle between the two arms 135. In this way, between the arms 135 The angular distance reaches the maximum. The component 195 is equivalent to a fixed-length rod. The two arms 135 are rigid with each other, so they can be rotated in the same time by the same 101715.doc -20- 200538184. Thus, one leg The action of stepping will trigger another-foot pedal action in the :: style. If you want this kind of situation, consider replacing the part 195 with a rigid rod, of course, in the beginning of the transition phase, you can use this to make a problem 'because of using The user must start the exercise with the pedals at a minimum distance from each other, thus balancing conditions. Jing Shi ^ When the minimum distance between the pedals is reached, and when the support

When the arms 135 are in their respective stop positions, or near the plane L in use, the members 95 can be consistent with the foot pedal 14 to prevent the angle between the arms 135 from exceeding a fixed value. This value can be borrowed Established by known and not shown devices for calibrating the springs 196 and 197 and the minimum length specified for the component 195 to ensure that the user maintains a balanced state. From the above description, it can be seen that 'machine || 1G1 also embodies the above-mentioned embodiment of the concept of the present invention' and can provide effective answers to the above-mentioned technology. As a result, even if the user has only been trained for a short time or has The short skating experience is also particularly convenient and safe.
