CONSTITUTION:In a state that a bearing table 4 is tilted by actuators 13-15 and a saddle and handles are tilted in the front and rear and to the left and right, according to the constitution of a user, the levels of the handles and a distance between the left and right are regulated by actuators 24, 25. Then, according to a previously set program, the handles can be rowed in a posture of tilt in the front, in the rear, to the left, or to the right. In this case, according to the requirement, the user can change a tilt angle with a control switch fitted on the handles. Accordingly, not only the leg power, the arm muscle, the breast muscle, and the abdominal muscle, but also the side muscle can be trained, and by complicated handle movement, the sense of equilibrium can be also trained. Besides, by enabling the distance between the left and right handle levers, to be regulated with the actuators, the stroke loop of a grip can be three-dimensionally formed.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a rowing machine, which is used as a health equipment or an entertainment equipment, and is operated by a user with a handle.

(Prior Art) Conventionally, a saddle is provided on a rail so as to be movable back and forth, a handle lever receives the load from the handle, and a step supports the foot. The rider moves the saddle back and forth through the movement, applies loads such as hydraulic pressure, springs, and weights to the handle lever, and uses arm strength to pull the handle lever in line with the forward and backward bending and stretching movements of the legs, causing it to rotate around a fixed fulcrum. 2. Description of the Related Art A rowing machine is known that is configured to perform exercise by tilting the entire body back and forth.

However, as mentioned above, conventional rowing machines are only configured so that the saddle can be moved back and forth and the handle lever can be moved back and forth in an arc centered on a fixed fulcrum. Because the boat not only travels in a straight line, but also pitches and rolls as it sways from side to side under the influence of the waves, the problem with conventional equipment is that it is not possible to practice oar rowing that corresponds to the actual movements. be.

(Problems to be Solved by the Invention) According to the present invention, it is an object of the present invention to provide a rowing machine that allows users to experience the same body movements as actually rowing a boat. The height and spacing can be adjusted, and the training effect can be enhanced by allowing the boat to take harsh maneuvering positions such as river rafting in port, or it can enhance the playability. The aim is to provide a rowing machine that enables complex training that not only trains leg strength but also develops a sense of balance.

(Means for Solving the Problems) According to the present invention, as shown in the drawings, the rail 3 that supports the seat 1 so as to be movable back and forth, the handle levers 32 and 33 that receive the handle load, and the step 42 are provided. The supporting stand 4 is supported by an actuator 13.14°15 so as to be tiltable back and forth and left and right, and the handle lever 32.33 is pivotally connected to the supporting stand 4 by a pivot shaft 30.31.

(Function) According to the present invention, the support base 4 is tilted by the actuator 13, 14, 15, and the height of the handle is adjusted according to the physique of the user while the saddle and the handle are tilted back and forth and/or left and right. By adjusting the distance between the left and right sides using the actuators 24 and 25, the handle can be rowed in a forward, backward, leftward, or rightward posture according to a preset program. At this time, the user can change the inclination angle as necessary using the control switch attached to the handle, which allows the user to train not only leg strength, arm muscles, chest muscles, and abdominal muscles, but also the side muscles. You can also develop your sense of balance by moving the handle.

Furthermore, according to the present invention, by making it possible to adjust the distance between the left and right sides of the handle lever using an actuator,
The stroke loop of the grip can be formed three-dimensionally.

(Embodiment) The drawing shows one embodiment of the present invention, and in the illustrated example, wheels 2 are attached to a saddle I, and the wheels 2 support the saddle 1 on a rail 3 so as to be movable back and forth. It is fixedly supported on a tilting support base 4.

The tilting support base 4 has a front end side arm 5 extending left and right at its front end.

．． The lower end of 8.9 is connected to the piston 16.17 of the hydraulic cylinder device 13.14.15 through the universal joint 10°11.12.
．． 18 is connected to the upper end of the hydraulic cylinder device 13.14.
The rail 3 is configured to be able to tilt forward, backward, left and right by the telescopic operation of the rail 15.

The tilting support 4 is further provided with central lateral arms 20.21 extending left and right from the tilting support 4 at a position forward from the center thereof, and an actuator support frame extending downward from the tips of these central lateral arms 20.21. Hydraulic cylinder devices 24, 25 for raising and lowering the handle lever are provided in 22 and 23, and a hydraulic cylinder device for adjusting the distance between the handle levers is attached to the lower end of a piston rod 26 and 27 that extends and retracts in the vertical direction of the hydraulic cylinder device 24 and 25 for raising and lowering the handle lever. 28.29 are installed.

The piston rods 30.31 of the hydraulic cylinder device 2829 for adjusting the distance between the handle levers protrude horizontally to the left and right, and the outer ends of these screw-in rods 30.31 constitute the pivot shaft of the handle lever, and The lower ends of the left and right bundle levers 32 and 33 are rotatably supported via bearings 34 and 35, respectively.

This allows the pivot shaft 3 of the left and right handle levers 32 and 33 to

It is pivotally attached to the support frame 8, and the tip of the piston rod is slidably connected along the handle 20 via a load adjustment guide prong 41. 42
43 represents a step, 43 represents a hydraulic unit, and 44 represents a controller.

Next, the operation of the illustrated rowing machine configured as described above will be explained.

The load on the handle lever, which rotates half a turn back and forth relative to the rail 3 in an arc around the fulcrum 30.31 of the handle lever 32.33, is handled by the handle load hydraulic cylinder device 38.
．． The expansion and contraction of 39 is performed using the fulcrum 40 and the load adjustment guide block 41.
It is determined by the expansion/contraction rate of the interval per time and the length ratio of the fulcrum 30.31 and the load adjustment guide block 41, and the fulcrum 30, 31 and the grip 36.37.

The movement loop of the grip part relative to the rail 3 can be moved almost in parallel from the start point to the end point of the grip movement by moving the fulcrum 30.31 up and down by the expansion and contraction of the hydraulic cylinder device 24.25, or it can be moved in a wavy manner. It is also possible to move in a straight line by setting the starting point high and the ending point low.

Further, a universal joint 12 at the lower end of the rear end support frame 9 of the rail support base 4 is connected to the upper end of the telescopic piston rod of the hydraulic cylinder device 15, and similarly the universal joint 10.11
Hydraulic cylinder device for handle load by 38.39
Since the fulcrum 40 of is connected to the upper end of the piston rod of the hydraulic cylinder device 13, 14, the hydraulic cylinder device 1
For example, when the front hydraulic cylinder device 13, 14 contracts and the rear hydraulic cylinder device 15 extends due to the expansion and contraction of 3.14.15, the user assumes a forward posture. Further, when the hydraulic cylinder devices 13 and 14 are expanded and contracted to tilt forward to the right, and the hydraulic cylinder device 15 is extended, the vehicle is tilted forward upward to the rear and to the left. In this case, if the hydraulic cylinder device 24 is extended and the hydraulic cylinder device 25 is retracted, the left and right grip positions will be at the same height with respect to the floor when the main body is installed, and when the user leans to the left, the left and right grip positions will be at the same height. This makes it possible to reduce the movement of the center of gravity. Conversely, if the hydraulic cylinder device 24 is retracted and the hydraulic cylinder device 25 is extended, the user can tilt more to the left, and the center of gravity shifts more, so the force of supporting the user's body weight with the left arm increases. In this way, the user can use the rowing machine in a variety of positions.

In the example described above, hydraulic cylinder devices 13, 14, 15, 24, 25, 28 and 29 are used as actuators, but a pneumatic cylinder device may also be used, and the operation of these actuators is controlled by a hydraulic or pneumatic unit 43. and by the controller 44. It is also possible to use an electric gear type actuator.

In addition, in the illustrated example, there are three hydraulic cylinder devices 13° and 14.
, 15 supports the support stand 4, but it goes without saying that the stability will be improved if it is supported by four hydraulic cylinder devices.

(Effects of the Invention) According to the present invention, it is possible to perform back-and-forth movement while leaning forward and backward and from side to side in a comfortable posture that suits the user's physique, and thereby, the user can only train arm strength and leg strength. It also develops a sense of balance and allows for advanced and complex training.
