この発明は体育器具、とくにボー1−を漕ぐ動作を行わ
せる体育器具の改良に関覆るしのである。。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to improvements in physical education equipment, particularly physical education equipment for performing the motion of rowing a bowl. .
従来、体力増強を目的として使用される体育器具として
ボートを漕ぐ動作を行わゼるものがあり、これはボー1
−のオールの役目をする揺動可能なハンドルをスプリン

造ではA−ルを引き終わって力を抜くとスプリングの力
で急激にオールが戻されることになり、実際のボートを
漕ぐ状態と異なるばかりでなく、引き終わったときに急
激に反対方向の力を加えられるために危険で:bある。Conventionally, there is a physical education equipment used for the purpose of increasing physical strength that performs the motion of rowing a boat.
A swingable handle, which acts as an oar, is biased in one direction by a spring, and the handle is made to swing against the force of the spring. With this structure, when you finish pulling the oar and release the oar, the force of the spring causes the oar to return suddenly, which is not only different from the situation when rowing an actual boat, but also when the oar is finished pulling, it suddenly moves in the opposite direction. It is dangerous because of the force applied to it.
またオールを引く際に引く邑に比例して力が増大するこ
とになるためボート漕ぎの臨場感に乏しいという欠点が
ある。さらに、オールを引く力は器具によって一定し°
Cおり、使用者に応じて力の調整をすることができない
という欠点がある。Another drawback is that when pulling the oar, the force increases in proportion to the amount of force being pulled, which makes rowing less realistic. Additionally, the force used to pull the oar is constant depending on the device.
However, the disadvantage is that the force cannot be adjusted depending on the user.
この発明は、このJ、うな従来の欠点を解消するために
なされたものであり、実際のボートを漕ぐ感しに近く、
力の調整し自由であり、ボート漕ぎの臨場感に溢れた体
育器具を提供4−るものである。This invention was made to eliminate the drawbacks of the conventional J-U, and it is similar to the feeling of rowing an actual boat.
The purpose of the present invention is to provide a physical education equipment that allows the user to freely adjust the force and provides a realistic feeling of rowing.

のである。That is, the present invention has a seat plate that is reciprocably arranged on a rail provided on a frame body, a tread plate provided on the frame body, and one end of which is swingably held by an arm protruding from the side of the frame body. The handle has a handle whose other end extends between the seat plate and the footboard, and a resistance means that applies a resistance force to the handle against rocking in one direction, and the resistance means narrows the fluid in a predetermined case. A check valve is provided in the flow path of the fluid to prevent circulation through the hole and to cause greater resistance to movement in one direction than movement in the other direction.

。In the above configuration, a person places his/her waist on the seat board 2, places his or her feet on the footboard 3, and pulls the handle 5, thereby causing the handle 5 to swing around the shaft 50. When you pull the handle 5, [
] Tsurad 4 is pulled out, which causes screw 1-63 to be pulled out.
moves to the right in Figure 6. As a result, the fluid in the first v71 flows into the third chamber 73 through the pore 68, and the flow resistance passing through the pore 68 at this time reduces the movement resistance of the histone 63, and therefore the swinging resistance of the handle 5. Jiru. The level of resistance can be freely set by adjusting the valve body 76. When the handle 5 is returned to the IWi direction, the piston 63 moves to the right in FIG. '1
There is almost no resistance to the inflow. ! l rope 1
), when pulling the handle 5, the resistance increases in proportion to the pulling force, and when returning the handle 5, there is almost no resistance and the handle is not pulled back, so the situation is the same as crushing an actual boat.

、。In addition, when setting the pulling force of the handle 5, pull the handle 5 with all the horns with the valve body 76 completely closing the pore 68, and measure the h horn at that time to determine the appropriate force for the user. It is also possible to know the resistance force and adjust the C valve body 7 (5) based on it.In addition, in the above embodiment, the resistance means is a piston that reciprocates in the cylinder, but for example,
A gear pump may be used, or a rotary piston may be used (although this is not limited to the embodiments).
