Hereinafter, preferred embodiments of the present invention will be described in detail based on the drawings.

First Embodiment
1 to 6 show a first embodiment of a vibrator for physical movement according to the present invention.

As shown in FIGS. 1 to 4, the vibrator includes a seat member 1 and a vibrating member 2. In the seat member 1, a floor plate 1b is laid on the rectangular frame 1a, and a drive source, a drive mechanism, and the like described later are installed on the floor plate 1b. The vibrating member 2 is formed of a rectangular frame 2a, and brackets 3 and 3 are vertically provided from the rectangular frame 2a at positions on both sides in the central width direction.

(Connection structure of seat member and vibrating member)

The swing arm 5 is pivotally connected at its lower end to the support means 4 via a pivot 7 and is pivotally connected at its upper end via the shaft means 6. Therefore, as described later, when vibrating the vibrating member 2 vertically, the vibrating member 2 vertically vibrates the seesaw structure centering on the shaft means 6, and when vibrating the vibrating member 2 laterally, the vibrating member 2 By swinging the swing arm 5 around the pivot 7, the left and right vibration is performed together with the shaft means 6.

However, the connecting structure of the seat member 1 and the vibrating member 2 uses the swing arm 5 as shown in the illustrated embodiment, extends the support means 4 upward, and provides a long guide hole in the lateral movement direction, The shaft means 6 may be inserted so as to be movable leftward and rightward along the guide hole.

(Configuration of seat member)
The seat member 1 has a single drive source 8 consisting of one electric motor installed on the floor plate 1b, and constitutes a first drive path 9 and a second drive path 10 for transmitting rotational drive force from the drive source 8 ing. In the case of the illustrated embodiment, the first drive path 9 and the second drive path 10 are configured with the one intermediate drive shaft 12 rotationally driven by the drive source 8 via the reduction pulley 11 as a common axis.

The intermediate drive shaft 12 constitutes a first shaft 12a and a second shaft 12b by dividing an intermediate portion in the axial longitudinal direction, and the shaft ends of both the shafts 12a and 12b are connected by the clutch means 13 consisting of a one way bearing 13a. The reduction gear pulley 11 is mounted on the first shaft 12a.

The one-way bearing 13a is a well-known mechanical component that does not transmit the rotational driving force to the output side shaft member by rotating the input side shaft member in the normal direction but not in the reverse direction. When the first shaft 12a is driven to rotate in the forward direction by rotating the source 8 forward, the second shaft 12b is also driven to rotate simultaneously, but conversely, the first shaft 12a is reversed by reversing the drive source 8 When rotationally driven in the direction, power is not transmitted to the second shaft 12b, and the second shaft 12b is configured to stand still.

The first drive path 9 constitutes an output portion by a first drive shaft 9 b rotationally driven by a first shaft 12 a of the intermediate drive shaft 12 via a reduction pulley 9 a, and the rotation of the first drive shaft 9 b A first motion converting means 14 is provided which is constituted by a first eccentric cam 14a which converts a motion into an up and down motion.

The second drive path 10 constitutes an output portion by a second drive shaft 10b rotationally driven by a second shaft 12b of the intermediate drive shaft 12 via a reduction pulley 10a. The rotation of the second drive shaft 10b A second motion converting means 15 is provided which is constituted by a second eccentric cam 15a which converts the motion into the vertical motion.

Although not shown, the power source of the electric motor constituting the drive source 8 is switched between ON / OFF and forward / reverse rotation of the electric motor by a switch provided on the main body of the vibrator or a separate remote control switch. Preferably, the switch stores a program for controlling forward and reverse rotation.

(Configuration of vibrating member)
The vibrating member 2 includes a driven piece 16 pivotally connected to the pivoting piece 14b of the first eccentric cam 14a and a driven piece 17 pivotally connected to the pivoting piece 15b of the second eccentric cam 15a. It is provided. Therefore, the vibration member 2 faces the seat member 1 from the upper side, and the brackets 3, 3 face the outer surfaces of the swing arms 5, 5 pivotally connected to the support members 4, 4. As shown in FIG. 4, by inserting the shaft means 6 in the insertion holes 3a and 3 and the upper insertion holes of the swing arm 5, it is installed in the upper position of the seat member 1, as shown in FIG. The pivoting piece 14b and the driven piece 16 of the eccentric cam 14a and the pivoting piece 15b and the driven piece 17 of the second eccentric cam 15a are pivotally connected, respectively. In the case of the illustrated example, a flanged cylinder 6a is externally inserted at both ends of the shaft means 6, and the bracket 3 and the swing arm 5 are pivotally connected by the cylinder 6a.

In the illustrated embodiment, the shaft means 6 is constituted by a single long shaft member, but is constituted by two short shaft members, and the brackets 3 and 3 and the swing The arms 5 and 5 may be configured to be coaxially pivoted, respectively.

As described above, the vibration member 2 and the seat member 1 disposed in the upper and lower connection state store the lower portion from the vibration member 2 in the casing, and the floor plate etc. By mounting, it is provided as a vibrator for physical exercise as a product.

(Operation of the first embodiment)
FIG. 5 shows the operation when the drive source 8 is rotated forward. The rotational drive force of the drive source 8 is transmitted to the intermediate drive shaft 12 to drive the first shaft 12a in the forward direction, and the rotational drive force of the first shaft 12a is transmitted to the second shaft 12b by the one way bearing 13a. That is, both the first drive path 9 and the second drive path 10 operate the power transmission function.

As a result, since the first motion converting means 14 is moved up and down by the rotational driving force of the first shaft 12a, the vibrating member 2 vibrates up and down in a seesaw structure around the shaft means 6 in small increments.

Further, since the second motion converting means 15 is moved laterally by the rotational driving force of the second shaft 12 b, the vibrating member 2 vibrates laterally in small steps through the swinging of the swing arm 5.

For this reason, by causing the drive source 8 to rotate in the normal direction, combined vibration in which both the vertical vibration and the horizontal vibration of the vibrating member 2 are simultaneously performed is performed.

FIG. 6 shows the operation when the drive source 8 is reversed. The rotational drive force of the drive source 8 is transmitted to the intermediate drive shaft 12 to drive the first shaft 12a forward, but the rotational drive force of the first shaft 12a is not transmitted to the second shaft 12b due to the free rotation of the one way bearing 13a. . That is, the first drive path 9 operates the power transmission function, but the second drive path 10 is at rest.

As a result, since the first motion converting means 14 is moved up and down by the rotational driving force of the first shaft 12a, the vibrating member 2 vibrates up and down in a seesaw structure around the shaft means 6 in small increments. However, since the second motion converting means 15 is at rest along with the second drive path 10, the vibrating member 2 is not vibrated in the lateral direction.

Therefore, only the single vibration due to the vertical vibration of the vibrating member 2 is performed by reversing the drive source 8.

As described above, the user can select normal rotation and reverse rotation of the drive source 8 according to preference by operating the switch, and further, switching between normal rotation and reverse rotation by reading the program. Can be performed automatically at predetermined time intervals.

Second Embodiment
7 and 8 show a second embodiment of the vibrator for physical movement according to the present invention. The basic configuration is the same as that of the first embodiment described above, so the same technical components are denoted by the same reference numerals, and the above description is incorporated.

In the case of the second embodiment, when the drive source 8 is rotated forward, the power transmission function of both the first drive path 9 and the second drive path 10 is operated, and both the vertical and horizontal vibrations of the vibrating member 2 are The second embodiment is the same as the first embodiment in that it enables combined vibration to be performed simultaneously, but when the drive source 8 is reversed, the power transmission function of the second drive path 10 is activated and the first drive path 9 is paused. It is configured to

For this reason, as illustrated, with respect to the first shaft 12a and the second shaft 12b of the intermediate drive shaft 12 connected by the one-way bearing 13a, the first drive path 9 is directed from the second shaft 12b to the first drive shaft 9b. The second drive path 10 is configured to be directed from the first shaft 12a to the second drive shaft 10b.

Thereby, when the drive source 8 is reversely rotated, the second motion conversion means 15 is moved laterally by the rotational drive force of the first shaft 12a in a state where the first drive path 9 is stopped together with the second shaft 12b, By swinging the vibrating member 2 sideways by swinging the swinging arm 5 little by little, only single vibration due to the left and right vibration of the vibrating member 2 is performed.

Third Embodiment
FIG. 9 shows a third embodiment of the vibrator for physical movement according to the present invention. In the case of the third embodiment, the intermediate drive shaft 12 is not divided as in the first and second embodiments, and therefore the one-way bearing 13a described above is not provided.

On the other hand, the first drive shaft 9b constituting the first drive path 9 is divided into an input shaft portion 18a rotationally driven by the reduction pulley 9a and an output shaft portion 18b provided with the first motion conversion means 14 A clutch means 13 is provided which comprises an electromagnetic clutch 13b for freely connecting and disconnecting transmission of rotational driving force between the two shaft parts. Similarly, the first drive shaft 10b constituting the second drive path 10 is divided into an input shaft portion 19a rotationally driven by the reduction pulley 10a and an output shaft portion 19b provided with the first motion conversion means 15 There is provided clutch means 13 consisting of an electromagnetic clutch 13c which allows connection and disconnection of transmission of rotational drive force between both shaft parts. Since the other configuration is the same as that of the first embodiment described above, the same technical component is indicated by the same reference numeral, and the above description is incorporated.

According to the third embodiment, a switch for electrically controlling the electromagnetic clutches 13b and 13c and a program are provided, whereby ON / OFF (connection / intermittent) of the electromagnetic clutch 13b provided on the first drive shaft 9b is provided. Since the ON / OFF (connection / intermittent) of the electromagnetic clutch 13c provided on the second drive shaft 10b can be performed separately, selection of the independent vibration of either the vertical vibration or the horizontal vibration of the vibrating member 2, and the vertical vibration It becomes possible to select the combination vibration which simultaneously performs both the vibration and the left and right vibration, and it is possible to secure the diversity of the vibration in the three modes.
