Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an elongated member exercise machine in which an elongated member such as a rope or a belt can be pulled by hand, and is used for exercise such as rowing a boat, etc. It is something that can be done.

The present invention may be constructed so that movements such as operating an expander can be performed as necessary.

[Prior Art] Conventionally, rowing machines that move levers and the like have been used to perform an exercise similar to rowing a boat, but these machines have a complicated structure and are expensive.

In addition, conventionally used expanders use helical springs, so when pulling, the resistance force is initially small and increases rapidly as the length of pull increases, making it difficult to use in many cases.

[Problems to be Solved by the Invention] The present invention provides an elongated member movement machine that has an extremely simple structure and is capable of performing movements such as rowing a boat and other movements.

The invention also provides an elongated member movement machine in which a constant resistance force is applied when pulling the elongated member.

[Means for Solving the Problems] The present invention includes an elongated member made of a flexible material such as a rope or a belt that can be pulled by a user's hand, and a method for moving the elongated member in at least a predetermined direction. and an energy absorbing device that absorbs energy by applying a resistive force to the elongated member.

The present invention also provides an elongated member moving machine characterized in that the elongated member is endless.

The present invention also provides an elongated member moving machine, wherein the energy absorbing device is based on a frictional force between the elongated member and a portion on which the elongated member is mounted.

[Examples] Examples of the present invention will be described below with reference to the drawings.

In one embodiment of the present invention shown in FIGS. 1 to 5,
10 is a mounting body; 12 is a base 13 of this mounting body; a hook portion made of a horizontal bar attached to the base; 14 is a support portion provided on the base 12; and 15 is one end of the base 12. This is a contact portion provided on both sides of the user's foot for contacting the user's feet.

16 is an endless elongated member made of rope, and 17 is an energy absorption device equipped with this elongated member. This energy absorbing device has a main body 18 and a lid 21 that can be attached and detached with a screw 20.
Three mounting parts 22 protruding from a circular cross section for bending and mounting the main body are formed integrally with the main body. Reference numeral 23 denotes two adjusting screws that are screwed into screw holes 25 cut in the lid 21 and pass through them, and a pressing member 26 rotatably attached to the inner end presses the elongated member 16 with an appropriate force. It is designed to provide initial tension. By adjusting this initial tension on the side where the elongated member 16 enters the body 18, the resistance or tensile force, which is the frictional force between the elongated member 16 and the mounting portion 22, can be adjusted. This tensile force increases exponentially with respect to the initial tension with respect to the total angle at which the elongated member 16 is mounted on the mounting portion 22. Reference numeral 27 represents an extension portion extending from both sides of the main body 18, and 28 represents a connecting member that connects the distal end portions of this extension portion. Reference numeral 30 denotes an engaging portion consisting of a recess formed from the lower surface of each extension portion 27, which is connected to the hook portion 13.
and is removably engaged with. In this state, the main body 18 is supported by the support portion 14 and is prevented from rotating downward beyond a predetermined amount. The support portion 14 may not be formed.

In the structure as described above, as shown in FIG. 6, the user places both feet in contact with the contact portion 15, grips one side of the elongated member 16 with both hands, and pulls it out to the state shown in the figure. You can exercise by repeating certain movements. The movement of pulling out the elongated member 16 is similar to rowing a boat or playing tug of war, and the pulling force is approximately constant. Alternatively, the user can perform a continuous pulling motion while alternately grasping one side of the elongated member 16 with the left and right hands. Alternatively, the elongated member 16 can be reciprocated by being pulled out alternately on both sides. Moreover, the user can also use it while sitting on a chair.

The usage example shown in FIG. 7 shows a case where the main body 18 is removed from the mounting body 10 and used as an expander.
The user grips a connecting member 28 (not shown) of the main body 18 with one hand and pulls out the elongated member 16 from the main body 18 with the other hand. In this case as well, the tensile force is adjustable and approximately constant.

In the embodiment shown in FIG. 8, the main body 18 is engaged with the upper hook 13a using a commercially available hanging device or a similar upwardly extending mounting body 10 made for the purpose of the present invention. Although the state in which the elongated member 16 is pulled out to one side is shown, it can also be used by engaging the main body 18 with a hook shown at 13b or 13c.

In this invention, the mounting body 10 is not used (for example, one leg is placed in contact with the connecting member 28, or, as shown in FIG. A long connecting member 28 connected between the extensions.
It may also be used by placing both feet in contact with.

Various further modifications can be made to each of the above embodiments. For example, a narrow belt may be used as the elongated member 16. Further, the shape and number of mounting parts 22 may be changed, such as by using only one semicircular mounting part 22 with a groove formed on its circumferential surface, or by using five mounting parts as illustrated and described. Alternatively, the adjustment screw 23 may be configured to be used only on one side and to pull out the elongated member 16 only from the opposite side.

In another embodiment of the invention shown in FIGS. 10 and 11, the mounting body 10 is not used (the energy absorbing device 1
7 at a predetermined position. In this embodiment, a contact portion 15 is formed on a main body 18 which is made up of a lower half portion 18a and an upper half portion 18b and can be disassembled and assembled, and a rotating shaft 32 disposed in the vertical direction is rotatably supported. be. The elongated member 16 is a groove wheel 3 fixed to a rotating shaft 32.
3, and the initial tension is adjusted using two adjusting screws 23. A friction disk 35 is fixed to the rotating shaft 32, and a contact member 38 rotatably attached comes into contact with the tip of an adjustment screw 36 that adjustably sets the frictional force. When the elongated member 16 is pulled to one side, the groove wheel 33 rotates together with the rotating shaft 32, and the disc 35 also rotates, so that energy is absorbed by friction.

A variety of different energy absorbing devices 17 can be used in which the elongate member 16 rotates the rotating shaft 32 as shown in FIGS. 10 and 11. For example, it is possible to use a hydraulic damper, or a damper that receives frictional force from a highly viscous liquid.

In each of the embodiments described above, the elongated member 16 is shown to be endless, but in the embodiment shown in FIG. 12, the elongated member 16 has both ends and the stopper 43 is attached.

The extension part 27 of the main body 18 is rotatably connected to the connecting part 40 of the mounting body 10 by means of a pin 41. In this embodiment, when the elongated member 16 is pulled out to one side, it is necessary to pull out the elongated member 16 to the opposite side, which is somewhat inconvenient, but it is sufficiently practical.

[Effects of the Invention] Since the present invention is constructed as described above, it can be constructed with an extremely simple structure and at low cost, and the tensile force for pulling out the elongated member 16 can be maintained at approximately a predetermined constant value, which is very effective. It has the effect of being easy to use.

In this invention, the use of the endless elongated member 16 has the advantage that it is very easy to use, especially since the energy absorbing device 17 can be continuously pulled out.

In this invention, the energy absorbing device 17 that absorbs energy by the frictional force between the elongated member 16 and the part on which it is mounted has a particularly simple structure.
