Description

BACKGROUND OF THE INVENTION

(a) Field of the Invention

The present invention relates to a training device with changeable operating direction, and more particularly to a training device that the position of a stand can be changed, allowing an operator to apply force to a first grip and/or a second grip on the stand in different direction, so as to achieve multiple training effects.

(b) Description of the Prior Art

People are now interested in exercising; they no longer only choose outdoor exercising, but will also select indoor exercising machines. However, most of the exercising machines, such as treadmill, bike fitness, or elliptical trainer, can only train muscles in a lower part of body, and cannot fully train muscles in an upper part of body.
A Taiwanese utility model patent M600638, discloses a symmetrical vertical turntable movement device, wherein an operating space is formed by two vertical turntables with their vertical table surfaces being disposed opposite to each other. In addition, each vertical table surface is provided with a grip, and the grip is disposed in the operating space, which in turn allows an operator to stand or sit in the operating space, with both hands holding the grips to train the upper part of body.
However, there must be two vertical turntables in the abovementioned patent, and the operating space between the two vertical turntables should be also large enough to allow the operator to operate comfortably. Therefore, the entire size of the symmetrical vertical turntable movement device will be too large to be put in an ordinary home for the operator to train at home.
Furthermore, a Taiwanese utility model patent M616525, discloses a multi-directional training device, including a seat, a stand, a spindle, a vertical turntable, a first grip and a second grip. The seat includes a main operating region, a first side operating region, and a second side operating region. An operator can choose any one location among the main operating region, the first side operating region, and the second side operating region, to operate the first grip and/or the second grip for training.
However, as the abovementioned seat includes the main operating region, the first side operating region, and the second side operating region, the area will be too large and the training device will take up too much space. In addition, it is not convenient to transport and move the training device as well.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Referring to FIG. 1 , FIG. 2 , FIG. 3 and FIG. 4 , a training device with changeable operating direction, according to the present invention, comprises a seat 1, a stand 2, a spindle 3, a vertical turntable 4, a first grip 5, a second grip 6, a resistance unit 8 and a control panel 9.
The seat 1 is disposed horizontally on an XY plane, and the XY plane is constituted by an X-direction and a Y-direction that are perpendicular to each other. In the present embodiment, the XY plane is a flat ground surface, and when an operator operates the present invention, the direction in which the operator's shoulder width is extended is the X-direction, and the direction in which the operator looks straight forward is the Y-direction.
The stand 2 is pivoted on the seat 1 in a Z-direction, and the Z-direction is perpendicular to the XY plane. The stand 2 is pivoted to the seat 1 by a pivot shaft 11, and in the present embodiment, the pivot shaft 11 is a bolt. After being pivoted, the stand 2 can rotate relative to the seat 1. The stand 2 is provided with a first side 21 and an opposite second side 22 in the X-direction. The stand 2 can include an outer casing 23 (as shown in FIG. 10 ) to protect internal structures and prevent from stain at a same time. To facilitate describing the structures of the present invention, the outer casing 23 is omitted in some drawings.
A bottom end of the stand 2 is provided with a swivel plate 24, and the seat 1 is provided with a base plate 12 corresponding to the swivel plate 24. The pivot shaft 11, in association with a gasket 111 and a bushing 112, is screwed in a first threaded hole 120 on the base plate 12, allowing the swivel plate 24 to be pivoted on the base plate 12. The swivel plate 24 is provided with two arc-shaped guide grooves 25 on an outer periphery of the axis of the pivot shaft 11, and two securing units 26 are disposed in the two guide grooves 25 correspondingly. Each securing unit 26 includes a handle 261 and a limiting member 262; in the present embodiment, the limiting member 262 is a screw rod. The handle 261 is connected to the limiting member 262 to apply rotational force to the limiting member 262. The limiting member 262 includes a male thread 264 (as shown in FIG. 6 ) and passes through the guide groove 25 to be screwed in the second threaded hole 121 on the base plate 12, thereby limiting the rotation of the swivel plate 24. Each limiting member 262 is sheathed with a sleeve 263 to prevent the limiting member 262 from directly hitting the guide groove 25. The securing unit 26 in the present embodiment is only one of many feasible securing structures, and other elements, such as bolt and nut, or element like a quick release component for a bike, are all feasible embodiments of the present invention.
The seat 1 includes a standing plate 13, and the standing plate 13 is at a distance to the stand 2 in the Y-direction. The standing plate 13 provides for the operator to stand. After the operator stands on the standing plate 13, the stand 2 is in front of the operator.
The spindle 3 is rotatably disposed on the stand 2 and is extended along a spindle axis 31. The spindle axis 31 is the axis of the spindle 3, and is parallel to the XY plane. Two ends of the spindle 3 are all provided with a threaded hole (not shown in the drawings).
Referring to FIG. 2 and FIG. 5 , the vertical turntable 4 is fixed on the spindle 3 and rotates along with the spindle 3. The vertical turntable 4 includes a circumference 41, and a first table surface 42 and an opposite second table surface 43 are disposed on two sides of the circumference 41. The first table surface 42 is on a same side as the first side 21; whereas the second table surface 43 is on a same side as the second side 22.
The first grip 5 is extended along a first axis 51, and the first axis 51 is parallel to the spindle axis 31. In addition, the first axis 51 is at a distance to the spindle axis 31 of the vertical turntable 4 radially. The first grip 5 is vertically pivoted on an end of a first connecting member 53 on the first side 21. The first connecting member 53 is parallel to the first table surface 42, and the other end of the first connecting member 53 is provided with a first groove 531. A first screwing piece 532 passes through the first groove 531 and is screwed in the threaded hole at the end of the spindle 3, so that the first connecting member 53 can be fixed on the spindle 3. By releasing the first screwing piece 532, sliding the first groove 531 with respect to the first screwing piece 532, and then re-securing the first screwing piece 532 by screwing, the distance between the first grip 5 and the spindle 3 can be adjusted, thereby changing the moment arm in operating the vertical turntable 4.
The second grip 6 is extended along a second axis 61, and the second axis 61 is parallel to the spindle axis 31. In addition, the second axis 61 is at a distance to the spindle axis 31 of the vertical turntable 4 radially. The second grip 6 is vertically pivoted on an end of a second connecting member 63 on the second side 22. The second connecting member 63 is parallel to the second table surface 43, and the other end of the second connecting member 63 is provided with a second groove 631. A second screwing piece 632 passes through the second groove 631 and is screwed in the threaded hole at the end of the spindle 3, so that the second connecting member 63 can be fixed on the spindle 3. By releasing the second screwing piece 632, sliding the second groove 631 with respect to the second screwing piece 632, and then re-securing the second screwing piece 632 by screwing, the distance between the second grip 6 and the spindle 3 can be adjusted, thereby changing the moment arm in operating the vertical turntable 4.
Preferably, as shown in FIG. 1 and FIG. 2 , the first grip 5 and the second grip 6 are at far locations of the vertical turntable 4 diametrically, so that when the spindle axis 31 is parallel to the X-direction and the operator holds the first grip 5 and the second grip 6 with his or her two hands, respectively, he or she can execute an alternate cyclic action. However, the first axis 51 of the first grip 5 and the second axis 61 of the second grip 6 can be also on a same axis. Therefore, when the spindle axis 31 is parallel to the X-direction and the operator holds the first grip 5 and the second grip 6 with his or her two hands, respectively, he or she can execute a simultaneous cyclic action on the same axis with the left or right hand.
Referring to FIG. 2 and FIG. 5 , the resistance unit 8 is disposed on the stand 2 and is connected to the vertical turntable 4. The resistance unit 8 includes a first belt 81, a first driven wheel 82, a second driven wheel 83, a second belt 84, a third driven wheel 85 and a resistance wheel 86. The first driven wheel 82 and the second driven wheel 83 are commonly fixed on a first rotation shaft 87, the first rotation shaft 87 is rotatably fixed on the stand 2, and the axis of the first rotation shaft 87 is parallel to the spindle axis 31. The third driven wheel 85 and the resistance wheel 86 are commonly fixed on a second rotation shaft 88, the second rotation shaft 88 is rotatably fixed on the stand 2, and the axis of the second rotation shaft 88 is parallel to the spindle axis 31. The vertical turntable 4 is connected to the first driven wheel 82 by the first belt 81, and the second driven wheel 83 is connected to the third driven wheel 85 by the second belt 84. The source of resistance wheel 86 can be magnetic resistance, motor, friction force resistance, water resistance, air resistance or electromagnetic brake.
Referring to FIG. 1 , the control panel 9 is disposed on the stand 2 for displaying related operation messages, such as rotation speed, resistance, predicted heat consumption and operation time of the vertical turntable.
Referring to FIG. 1 , FIG. 6 , FIG. 7 and FIG. 8 , to change the relative position between the stand 2 and the seat 1, the handles 261 are first used to release the limiting member 262 by rotation (as shown in FIG. 6 and FIG. 7 ), such that the swivel plate 24 will no longer be abutted to the base plate 12. Next, the stand 2 is rotated to adjust the relative position between the stand 2 and the seat 1. Then, the handles 261 are used to tighten the limiting member 262 by rotation (as shown in FIG. 8 ), allowing the swivel plate 24 to be abutted with the base plate 12. Therefore, the stand 2 can be fixed on the seat 1.
For ease of description, the change in position of the stand 2 is described by a first mode and a second mode, in the present embodiment. As shown in FIG. 1 and FIG. 2 , in the first mode, the spindle axis 31 is in the same direction as the X-direction, and the first axis 51 of the first grip 5 as well as the second axis 61 of the second grip 6 are parallel to the direction in which the operator's shoulder width is extended. This means that the first axis 51 and the second axis 61 are all in the same direction as the X-direction, and the operator stands on the standing plate 13 and faces the stand 2, with his or her two hands holding the first grip 5 and the second grip 6, respectively, to rotate alternately with his or her two hands, for training muscles in the hands. At this time, the rotation resistance of the vertical turntable 4 can be changed by adjusting the resistance of the resistance unit 8, thereby acquiring the training effect in various strength.
FIG. 9 and FIG. 10 manifest the state of second mode. In the second mode, the spindle axis 31 is in the same direction as the Y-direction, and the swivel plate 24 in FIG. 9 rotates by 90° against the pivot shaft 11 following the arrow and is fixed on the base plate 12 of the seat 1 by the securing unit 26. Under the second mode, the first axis 51 of the first grip 5 is perpendicular to the direction in which the operator's shoulder width is extended. It means that the first axis 51 is in the same direction as the Y-direction, the operator also stands on the standing plate 13 and faces the stand 2. At this time, the operator can use a single hand to hold the first grip 5, rotating the vertical turntable (not shown in the drawings). The operator can also use both hands to hold the first grip 5 together, rotating the vertical turntable (not shown in the drawings). Similarly, by adjusting the resistance of the resistance unit (not shown in the drawings), the operator can change the rotation resistance of the vertical turntable (not shown in the drawings) to acquire the training effect in a various level. Under the second mode, the operator can operate with a single hand or both hands to train the muscles in different parts of the hands, by rotating in the direction parallel to the shoulder (i.e., the X-direction).
For the abovementioned first mode and second mode, the stand rotates by 90° relative to the seat. However, in the present invention, the rotation angle is not limited to 90°; the rotation by an angle of smaller than or larger than 90° is feasible according to the embodiment of the present invention. For the rotation angle larger than 90°, it can be achieved by properly increasing the arc length of the guide groove 25 in FIG. 4 .
Referring to FIG. 1 and FIG. 2 , when the operator feels that the operating radius of the first grip 5 or the second grip 6 is too large, i.e., the operator's arms swing too large, the first screwing piece 532 and the second screwing piece 632 can be loosened by rotation so that the first connecting member 53 and the second connecting member 63 can be moved and the first groove 531 and the second groove 631 are movable relative to the first screwing piece 532 and the second screwing piece 632, respectively, which in turn enables the first grip 5 and the second grip 6 to move close to or away from the spindle axis 31, thereby changing the operating radius of the first grip 5 or the second grip 6. When the operator feels that the operating radius of the first grip 5 or the second grip 6 is proper, he or she re-tightens the first screwing piece 532 and the second screwing piece 632, enabling the first grip 5 or the second grip 6 not to be loosened, which assures that the operating radius can keep constant during operation, thereby fitting a various need of the operator.
By rotating the stand 2, the relative position between the stand 2 and the seat 1 is changed, so that the operator can rotate the vertical turntable 4 by various angles at a same location, thereby acquiring the various training effect. In addition, the standing plate 13 will not take up too much area and space.
The standing plate 13 can be omitted. If the seat 1 is fixed on the ground directly by a securing element, such as bolt, the stand 2 can also rotate on the seat 1 relatively, and the operator can operate while standing on the ground.
The operator can freely choose to use a single hand or both hands to operate at various angles to execute various trainings. He or she can train both hands simultaneously, and can carry out an intensive training to the left hand or right hand respectively, which facilitates the operator to enhance the training to the upper body, such as shoulder, elbow, or wrist, according to his or her personal need.
It is of course to be understood that the embodiments described herein is merely illustrative of the principles of the invention and that a wide variety of modifications thereto may be effected by persons skilled in the art without departing from the spirit and scope of the invention as set forth in the following claims.
