Description

  The present invention relates to an exercise assisting device that allows a user to exercise by cycling.

  Conventionally, a number of exercise assistance devices that enable exercise by bicycle rowing indoors have been proposed. This type of exercise assist device is formed in a fixed bicycle type, and by applying a load to the rotation of the pedal, an appropriate load is applied to the muscle group of the user's leg, and the respiratory system and the circulatory system are It is used for the purpose of activation (for example, refer to Patent Document 1). Various configurations have been proposed for generating loads, such as those using eddy currents, those using frictional resistance, and those using viscous torque.

On the other hand, an exercise assisting device that simulates riding exercise has been proposed for use in strengthening the back and back muscle group and balance training (see, for example, Patent Document 2). The exercise assisting device described in Patent Document 2 has a seat on which a user is seated, and the user is trying to maintain balance by swinging the body of the user seated on the seat.

  By the way, in the exercise assistance apparatus which performs the bicycle rowing exercise | movement described in patent document 1, the apparatus which generate | occur | produces a load is required in order to acquire an exercise effect, and if the load to give becomes large, the apparatus which generate | occur | produces a load will also enlarge. . Patent Document 1 describes a device that generates a load by using a viscous torque. Although this device is small, it cannot generate a load that can strengthen muscle strength.

  In addition, since the exercise assisting device described in Patent Document 1 can only perform a bicycle rowing exercise, it can give stimulation to the muscle groups of the legs, but there is almost no stimulation to other muscle groups, and systemic exercise. The effect cannot be expected. Since the muscles having a large volume in the body include not only the legs but also the back and back muscles, exercise that stimulates at least the back and back muscles is desirable. The lumbar spine muscle group can be strengthened by the exercise assisting device described in Patent Document 2, but the configuration described in Patent Document 2 cannot strengthen the leg muscle group.

  The present invention has been made in view of the above-mentioned reasons, and the object thereof is to reduce the size of a device that generates a load while performing a bicycle rowing exercise, and to balance not only the muscle groups of the legs but also the balance. An object of the present invention is to provide an exercise assisting device capable of stimulating other muscle groups necessary for maintenance.

  According to a first aspect of the present invention, there is provided a vehicle having a support portion that supports a part of a body of a user who has boarded the vehicle, a pedestal that supports the vehicle, and a swinging device that swings the support portion with respect to the pedestal. The swing device includes a pair of left and right pedals on which a user who rides the vehicle puts his left and right feet, a crankshaft that is the center of rotation of both pedals and that rotates by the user's bicycle rowing motion, and the rotational force of the crankshaft And a drive unit that converts the oscillation into swinging of the support unit.

  According to this configuration, since the support portion supporting the user swings by scooping the pedal and rotating the crankshaft, the user can generate a force for swinging his / her body by himself / herself. Compared with a simple bicycle rowing exercise, the load acting on the user's leg can be increased. In other words, in a simple bicycle rowing exercise, it is set only by a device that generates a load. However, in the configuration of the invention of claim 1, the weight of the user is utilized by adopting the configuration of swinging the support portion. Since a load can be applied to the leg portion, a relatively large load can be applied to the leg portion without using a load generating device. In other words, the load generating device can be reduced in size, and the size can be reduced while applying a relatively large load to the legs.

  Further, when the user's body swings with the swinging of the support portion, the muscle group necessary for maintaining balance is stimulated, and the balance function is trained. In addition, since it is possible to perform exercises that combine pedaling exercises and exercises that maintain balance against body swinging, it is possible to perform exercises that are close to full-body exercises, while reducing the burden on individual muscles while increasing energy. Consumption can be achieved, and an exercise effect in a short time can be expected.

  According to a second aspect of the present invention, in the first aspect of the present invention, the support portion is a seat on which a user is seated.

  According to this configuration, when only the seat is provided, the user uses the muscle group to balance the upper body, so that the same muscle group as when riding a unicycle is expanded and contracted. An exercise assisting device suitable for function training can be provided.

  According to a third aspect of the present invention, in the first or second aspect of the present invention, the support portion is a handle that a user grips with a hand.

  According to this configuration, the handle that the user grips with his / her hand is swung. Therefore, the configuration in which only the handle is swung is compared with the configuration in which the seat is swung as in the configuration of claim 2. There is little movement of the center of gravity, and you can exercise with light load. Further, in the configuration in which the seat is also swung together with the handle, the center of gravity movement is larger and the load is increased than in the configuration in which only the handle is swung, but the user holds only the seat by gripping the handle. Compared to the case of swinging, the balance of the upper body is less likely to be lost, and it can be used with a light load.

  According to a fourth aspect of the present invention, in any one of the first to third aspects of the present invention, the drive unit includes a first drive unit that converts the rotational force of the crankshaft into a reciprocating movement before and after the support unit, and a crank. And a second drive unit that converts a rotational force of the shaft into a left and right reciprocating movement of the support unit.

  According to this configuration, since the swinging back and forth and the left and right, particularly by swinging back and forth, the large back muscle group of the human body muscles can be expanded and contracted, and it is possible to exercise efficiently in a short time. it can.

  According to a fifth aspect of the present invention, in the fourth aspect of the present invention, the swing device is pivotally attached to the base so as to be swingable in one of front and rear and left and right, and the support portion is moved back and forth. And a movable base attached to the first drive unit and the second drive unit, the first drive unit and the second drive unit, One has a connecting rod whose lower end is coupled to the pedestal and whose upper end is displaced up and down, and the other of the first drive unit and the second drive unit has one end coupled to the support and the other end It has a connecting link that is displaced back and forth.

  According to this configuration, the swinging direction of the support portion is defined in the front-rear direction and the left-right direction by the shaft-mounting portion of the movable frame with respect to the base and the shaft-mounting portion of the support portion with respect to the movable frame. By driving the movable gantry and the support portion to be swung by the portion and the second drive portion, the support portion swings in combination of front and rear and left and right. Moreover, since the connecting rod moves up and down and the connecting link moves back and forth, the movement is simple and can be realized easily.

  According to a sixth aspect of the present invention, in any one of the first to fifth aspects of the present invention, the drive unit includes one motor capable of transmitting rotational force to and from the crankshaft in both directions. When transmitting the rotational force from the motor to the motor, a load that consumes the electric power generated by the motor is connected to the motor, and when the electric power is supplied from the outside to the motor, the rotational force of the motor is transmitted to the crankshaft. To do.

  According to this configuration, a single motor can be used as both a load and a drive source simply by switching between transmitting torque from the crankshaft to the motor and transmitting rotation from the motor to the crankshaft. it can. When used as a load (mechanical load), the load acting on the legs of the user can be changed depending on the magnitude of the load (electric load) connected to the motor. In addition, when the motor is used as a drive source, the support portion can be automatically swung, and the pedal can be automatically rotated around the crankshaft, which is necessary for the balance function as the support portion swings. The muscle groups expand and contract, and the leg muscle groups expand and contract as the pedal rotates. That is, various muscle groups can be expanded and contracted by passive movement without the user consciously moving the body, and a high exercise effect close to whole body movement can be obtained while performing the passive movement.

  According to the configuration of the present invention, the support portion supporting the user swings by scooping the pedal and rotating the crankshaft, so that the user generates a force for swinging his / her body by himself / herself. Thus, there is an advantage that the load acting on the leg portion of the user can be increased as compared with a simple bicycle rowing exercise. In addition, since the load is applied to the leg portion by utilizing the user's own weight, a relatively large load can be applied to the leg portion without adding a separate device for applying the load, and the size can be reduced. There are also advantages. In addition, since the user's body swings with the swinging of the support part, the muscle group necessary for maintaining balance is stimulated, and not only strengthening the leg muscle group but also training of the balance function. There is also an advantage. In this way, the exercise is a combination of the exercise of pedaling and the exercise of maintaining balance with respect to the swing of the body, so that the exercise is close to the whole body exercise, and while reducing the burden on individual muscles, There is also an advantage that it can be consumed and an exercise effect can be expected in a short time.

  In the present embodiment, as shown in FIG. 1, a vehicle 1 having a seat 11 as a support portion that supports a user's buttocks by being seated by the user and placed (or installed) on a floor or the like. The pedestal 3 (see FIG. 2) and the swinging device 2 (see FIG. 2) mounted on the pedestal 3 and swinging the seat 11 are configured. The seat 11 is formed as a chair with a backrest in the illustrated example, but may be formed like a saddle of a bicycle without a backrest as will be described later. Further, the oscillating device 2 is covered by a movable housing 20 that is movable with respect to the base 3.

  The rocking device 2 used in the present embodiment will be described with reference to FIGS. The swinging device 2 is a mechanism that performs reciprocating motions in the front and rear and the left and right respectively. With respect to the seat 11, the front and rear direction, the left and right direction, the up and down direction, the rotation around the front and rear direction (rolling), Among the operations with six degrees of freedom of rotation (pitching) and rotation around the vertical direction (yawing), a movement excluding yawing is given. In the drawing, the coordinate axes are shown in a right-handed system with the x direction in the front, the y direction in the left, and the z direction in the top. Rolling is rotation around the x axis, pitching is rotation around the y axis, and yawing is rotation around the z axis.

  As shown in FIG. 2, the oscillating device 2 has a movable gantry 21, and the movable gantry 21 is pivotally attached to the pedestal 3 so as to be oscillated left and right. Further, the movable base 21 is pivotally attached so that the lower end portion of the swing plate 41 coupled to the lower end portion of the movable pole 22 can swing back and forth, and the upper end portion of the movable pole 22 is connected to the seat 11. The seat post 12 (see FIG. 1) is attached in a nested manner. Therefore, the seat 11 can swing back and forth and from side to side. This movement of the seat 11 includes displacement components in the front-rear direction, the left-right direction, and the up-down direction, and also includes rolling and pitching.

  The rocking device 2 will be described in more detail. On the upper surface of the base 21, a pair of shaft support plates 31a and 31b (right and left direction in FIG. 2) separated from each other in the front-rear direction are provided upright. On the other hand, the movable base 21 is a corner formed by a pair of left and right side frame plates 32a and 32b, and a front frame plate 33a and a rear frame plate 33b that connect the front end portion and the rear end portion of both side frame plates 32a and 32b, respectively. Connecting plates 34a and 34b that are formed in a cylindrical shape and overlap the respective shaft support plates 31a and 31b are suspended from the lower ends of the front frame plate 33a and the rear frame plate 33b, respectively. The shaft support plates 31a and 31b are provided with bearings 35a and 35b, respectively, and the connecting plates 34a and 34b are connected to the shaft support plates 31a and 31b by a pair of front and rear shafts 36a and 36b supported by the bearings 35a and 35b. Each is attached to the shaft. That is, the movable base 21 is pivotally attached to the respective shaft support plates 31a and 31b provided on the base 21 using the front and rear shafts 36a and 36b, and the movable base 21 can swing left and right about the front and rear shafts 36a and 36b. become.

  Bearings 42a and 42b are provided at the lower rear ends of the left and right side frame plates 32a and 32b of the movable base 21, respectively. The swing plate 41 includes a pair of side plates and has a shape in which the front ends of the side plates 43a and 43b are connected. The lower end of the movable pole 22 is fixed between the upper ends of the side plates 43a and 43b. 43a and 43b are formed so that a space | interval may be expanded toward the lower part. The lower ends of both side plates 43a and 43b of the swing plate 41 are pivotally attached to the side frame plates 32a and 32b by a pair of left and right shafts 44a and 44b that are pivotally supported by the bearings 42a and 42b. Therefore, the seat 11 coupled to the movable pole 22 via the seat post 12 can swing back and forth about the left and right shafts 44a and 44b.

  By the way, in order to cause the movable base 21 to swing left and right with respect to the pedestal 3 and to apply a force to swing the movable pole 22 back and forth with respect to the movable base 21, the drive unit 50 is applied to the swing device 2. Is provided. The drive unit 50 constitutes the swing device 2 together with the movable base 21 and the swing plate 41.

  In the present embodiment, as a drive source of the drive unit 50, a rotational force generated by a bicycle rowing motion by a user and a rotational force generated by the motor 51 can be used. Below, the structure using the rotational force generated by human power will be described first, and then the structure using the rotational force generated by the motor 51 will be described.

  In order for a user seated on the seat 11 to perform a rowing exercise, pedals 23 are arranged on both the left and right sides of the movable housing 20, and each pedal 23 is connected to a crankshaft 25 via a crank 24. This structure is similar to the structure generally known in bicycles. Therefore, when a foot is put on the pedal 23 and the left and right pedals 23 are alternately depressed to perform a bicycle rowing exercise, the crankshaft 25 that is the rotation center of the pedal 23 rotates. The crankshaft 25 is pivotally supported by bearings 37a and 37b provided on the left and right side frame plates 32a and 32b.

  The drive unit 50 converts the rotational force of the crankshaft 25 into the forward and backward swings of the swing plate 41 with respect to the movable base 21, and the rotational force of the crankshaft 25 to the left and right swings of the movable base 25. A second drive unit for conversion. That is, the first drive unit swings the seat 11 back and forth by the rotational force of the crankshaft 25, and the second drive unit swings the seat 11 left and right by the rotational force of the crankshaft 25.

  The first drive unit includes a first gear 52 that rotates as the crankshaft 25 rotates, a second gear 53 that meshes with the first gear 52, and an eccentric that is attached to the shaft 54 that is the rotation shaft of the second gear 53. It comprises a cam 55 and a connecting link 56 having a cam hole 56 a that serves as a cam follower for the eccentric cam 55. The connecting link 56 is pivotally attached to the rear end portion of the fixed arm 45 attached so as to protrude rearward from the swing plate 41 with a left and right axial pin 46. Both end portions of the shaft 54 are pivotally supported by bearings 38 a and 38 b provided on the side frame plates 32 a and 32 b of the movable mount 21. The fixed arm 45 is attached to the side plate 43 a of the swing plate 41, and the side plate 43 a is inclined with respect to the side frame plates 32 a and 32 b of the movable mount 21, and is not parallel to the connection link 56. Therefore, a spacer (not shown) is interposed at the shaft attachment portion between the fixed arm 45 and the connecting link 56.

  Since the first drive unit has the above-described configuration, when the crankshaft 25 rotates, the first gear 52 rotates, and when the shaft 54 rotates due to the rotation of the second gear 53 that meshes with the first gear 52. As the eccentric cam 55 rotates and one end of the connecting link 56 rotates eccentrically with the rotation of the eccentric cam 55, the fixed arm 46 pivotally attached to the other end of the connecting link 56 reciprocates back and forth. Thus, the swing plate 41 reciprocates back and forth. By this operation, the seat 11 reciprocates back and forth.

  On the other hand, the second drive unit combines the first gear 52, the second gear 53, and the shaft 54 with the first drive unit, and the shaft 54 has a center of rotation at one end (left end) of the shaft 54. Different eccentric shafts 61 are provided. The eccentric shaft 61 protrudes to the left of the side frame plate 32 a in the movable mount 21. An upper end portion of a connecting rod 62 that constitutes the second drive unit together with the eccentric shaft 61 is pivotally attached to the eccentric shaft 61, and a lower end portion of the connecting rod 62 is attached to a bearing plate 63 having a U-shaped horizontal section fixed to the pedestal 3. It is coupled to be rotatable. The connecting rod 62 and the bearing plate 63 are coupled to the bearing plate 63 in such a manner that the connecting rod 62 can be rotated forward and backward and left and right.

  Since the second drive unit has the above-described configuration, when the crankshaft 25 is rotated and the shaft 54 is rotated in the same manner as the first drive unit, the movable base 21 is restrained by the eccentric rod 62 by the eccentric rotation of the eccentric shaft 61. Moves back and forth around the front and rear axes 36a and 36b. That is, the seat 11 reciprocates left and right.

  As described above, when the user seated on the seat 11 performs a bicycle rowing operation in which the left and right pedals 23 are alternately depressed, the crankshaft 25 rotates, and the rotational force of the crankshaft 25 is caused by the first drive unit to swing the swing plate. 41, and the rotational force of the crankshaft 25 is converted into the left and right reciprocating movements of the movable gantry 21 by the second drive unit. Therefore, the seat 11 coupled to the swing plate 41 is The swing is a combination of the reciprocating movement and the left and right reciprocating movements. In this embodiment, since the eccentric cam 55 and the eccentric shaft 61 are provided on one shaft 54, the ratio of the period of the back and forth reciprocation and the left and right reciprocation is 1: 1, The amplitude of motion and the amplitude of left and right swing can be changed by design.

  In the above-described configuration, the seat 11 simply moves reciprocally on a straight line or turns in one direction. Therefore, another gear (meshing) is provided between the shaft 54 and the eccentric shaft 61 so that the rotation cycles of the eccentric cam 55 and the eccentric shaft 61 are different so that the movement of the seat 11 is complicated. Also good.

  Incidentally, the shaft 54 is provided with a worm wheel 57, and the worm wheel 57 attached to the output shaft 51 a of the motor 51 is engaged with the worm wheel 57. That is, when the shaft 54 rotates, the rotational force is transmitted to the output shaft 51 a of the motor 51 through the worm wheel 57 and the worm 58. If the output shaft 51a of the motor 51 rotates, the motor 51 functions as a generator and generates an electromotive force. Therefore, if an appropriate load (electrical load) is connected to the motor 51 so as to consume this electromotive force. The load (mechanical load) for rotating the crankshaft 25 changes according to the magnitude of the load. That is, when the crankshaft 25 is rotated by a bicycle rowing motion, the motor 51 can be used as a load generating means. As the motor 51, a motor 51 whose output shaft 51a protrudes only in one direction is used.

  The motor 51 is fixed to the movable mount 21 by a motor mounting plate 39, and is held so that the output shaft 51a protrudes obliquely upward. By attaching the motor 51 in an inclined manner as described above, the internal space of the movable mount 21 is effectively used, and the dimensions of the movable housing 20 in the front-rear direction and the vertical direction are made as small as possible.

  Legs 3 a are attached to the pedestal 3, and a large number of air holes 26 are formed in the front portion of the pedestal 3. A large number of heat radiation holes 27 are formed in the front side surface of the movable housing 20. Therefore, the heat generated inside the movable housing 20 is radiated by the air flow flowing between the air hole 26 and the heat radiating hole 27, and the internal space of the movable housing 20 can be prevented from being overheated.

  By the way, the seat post 12 nested in the upper end of the movable pole 22 can be fixed at an arbitrary position with respect to the movable post 22 by a quick lever (not shown) provided at the upper end of the movable pole 22. It has become. The quick lever is a mechanism used for raising and lowering the saddle in a general bicycle, and is configured to expand and contract the opening diameter of the upper end portion of the movable pole 22 using the lever. If the opening diameter is increased, the seat post 12 can be freely moved up and down, and the seat post 12 can be fixed at the position when the opening system is contracted while the seat post 12 is kept at a desired height position. It has become.

  In the configuration of the present embodiment, the seat 11 is provided with a backrest to prevent the seat 11 from falling from the seat when the seat 11 is tilted backward, but the backrest is not essential. That is, as shown in FIGS. 6 and 7, a seat 11 having only a seat portion on which a buttock is placed without providing a backrest may be used as in the case of a bicycle saddle. In the illustrated example, an operation indicator 4 is provided on the upper surface of the front end portion of the seat 11. The operation display unit 4 has a function of inputting the magnitude of the load connected to the motor 51, the exercise time, or the calorie consumed by exercise combining them (such as inputting the body weight in advance or measuring the heart rate). It is possible to display (preferably). Further, if the load connected to the motor 51 is switched by operating the operation display unit 4, the exercise load can be adjusted.

  With the above-described configuration, when a user sitting on the seat 11 performs a bicycle rowing exercise, the leg muscle group can be strengthened by applying an appropriate load to the leg muscle group, and at the same time the seat 11 is shaken. By moving, the user expands and contracts the muscles of the lumbar spine muscles in order to maintain balance, and stimulates the organs necessary for maintaining the balance, thus also training the balance function. Since not only leg muscle groups such as the thighs and lower leg parts but also the lumbar spine muscle groups are stimulated, many muscles are expanded and contracted, so that an exercise effect close to whole body exercise can be obtained. Moreover, the leg muscle group and the dorsidorsal muscle group are muscles with a large volume in the body. Therefore, even if the individual muscles are lightly loaded, the overall amount of exercise increases, and a high exercise effect can be obtained. it can. In addition, the load acting on the muscle groups of the legs by the rowing exercise is used to swing the seat 11, and since the user is seated on the seat 11, the weight of the user is the leg. By utilizing as a load on the muscle group of the part, a relatively large load can be applied to the leg musculature while reducing the load generated by the motor 51. That is, it becomes possible to form the whole compactly using the small motor 51.

  When the pedal 23 is pedaled, the crankshaft 25 can be rotated in the forward direction as well as in the reverse direction, and a muscle group different from the normal direction is used for the reverse rotation. In particular, if it is reversed, a load can be applied to the muscle group in the region from the back of the thigh to the buttocks, so that a so-called hip-up effect can be expected.

  By the way, since the shaft 54 and the motor 51 transmit the rotational force via the worm 58 and the worm wheel 57, it is possible to transmit the rotational force in both directions between the shaft 54 and the motor 51. Therefore, instead of using the motor 51 as a load by depressing the pedal 23 and rotating the crankshaft 25, the motor 51 can also be used as a drive source by energizing the motor 51 and rotating the rotating shaft 51a. It is. When the motor 51 is rotated, the shaft 54 rotates, so that the seat 11 can be swung, and the rotational force of the shaft 54 is also transmitted to the crankshaft 25. As a result, the pedal 23 also moves.

  If power is supplied to the motor 51 and the motor 51 is rotated, the user sitting on the seat 11 can pierce the leg placed on the pedal 23 without consciously carrying out the bicycle rowing exercise. As a result, the leg muscles expand and contract, and the back and back muscle group is used to maintain balance by swinging the seat 11. Such movement is called passive movement, and the user's muscles expand and contract without the user's conscious movement.

  That is, one motor 51 can be used as a load during exercise or as a drive source. This switching is performed using the operation display unit 4. When power is supplied to the motor 51, the power of the operation display unit 4 may be diverted from the power supplied to the motor 51. However, when the motor 51 is used as a load, no power is supplied from the outside. It will be used for. In view of this, it is conceivable to use a battery as a power source for the operation display unit 4, but in this embodiment, a configuration using electric power generated by the motor 51 is employed. Since the voltage of this electric power varies depending on the degree of movement of the user, the voltage generated by the motor 51 is smoothed and constant using a power supply circuit. Further, since an electric load such as a resistor is also connected to the motor 51, an input to the power supply circuit is given so that priority is given to the power supply to the operation display unit 4 when the output power of the motor 51 decreases. The voltage and the input current are monitored, and the current path to the load is cut off when the input voltage and the input current are below a specified value. The wiring from the motor 51 to the operation display unit 4 is passed through the movable pole 22 and the seat post 12.

  In the configuration example described above, the vehicle 1 is configured as if it is a unicycle by providing only the seat 11 in the vehicle 1, but a handle that is gripped by a hand as a bicycle is supported as a support portion that supports the user's hand. It may be provided. If the handle is integrated with the seat 11, it can be swung together with the seat 11, and if it is swung separately from the seat 11, a complicated movement can be realized by a combination of swinging of the seat 11 and the handle. it can. Further, the handle may be fixed without swinging. Alternatively, it is possible to employ a configuration in which the seat 11 is fixed and only the handle is swung. In the above configuration example, the user has a function of voluntarily exercising by bicycle rowing exercise and a function of causing the user to perform a passive exercise by supplying power to the motor 51. It is not necessary to provide a function for performing other dynamic exercises.

  The configuration of the swing device 2 described in the present embodiment is an example, and various other mechanisms can be used as long as the support unit provided on the vehicle 1 can swing. .
