Description

[Detailed explanation of the invention] [Industrial application field] This invention is a training and
It's about machines.

[Conventional technology and its problems]

A variety of training machines have been proposed and put into practical use, but most of them are single-function machines that are mainly used for one type of training, and rarely two or three types of training machines. There are multifunctional models that can be used for training, but in most cases, they use heavy weights to load the user, so they are heavy, and multifunctional models in particular require large-scale equipment. Not only are they expensive to install, but they also have the disadvantage of being difficult to move once installed.

[Means for solving problems]

The present invention was made with the purpose of solving the problems of the prior art as described above and providing a training machine that is simple and lightweight and can be used for various types of training. , two cylinders are erected at appropriate intervals on one side of a base having a rectangular planar shape, etc., and a plurality of spiral springs are individually fixed at the lower ends of the inner and lower parts of the cylinders, and the interior can be opened freely. The upper end of the spiral spring is engaged with a support rod integrally provided with a mounting member of a lower pulley disposed inside the cylinder so as to be movable up and down, and the upper pulley is rotated to a fixed position at the upper end of the cylinder. Attach the cable by fixing it freely, wrap the cable around the upper and lower pulleys two or more times, lead the tip of the cable to the base side of the upper end of the cylinder, and attach it directly to the tip or to a base such as the bottom of the cylinder. A training member is attached through a pulley or the like provided on the table side, and the load at the tip of the led out rope can be adjusted by individually controlling the fixing and releasing states of the lower ends of the plurality of spiral springs. It is characterized by the following.

[Effect of invention]

That is, the present invention uses a spiral spring as a load on the user, and fixes the lower end of one or more of the spiral springs to the respective lower parts of two cylinders erected on one side of the base. an upper pulley which is installed inside the helical spring so as to be freely openable and whose upper end is fixed to a support rod integrated with a mounting member of the lower pulley which is loosely mounted in the cylinder, and which is rotatably mounted in a fixed position on the upper end of the cylinder; A cable is wrapped around the lower pulley, and the tip of the cable is led out to the base side of the upper end of the cylinder, and the tip of the cable is wrapped around the lower pulley.
Attach a handle or other appropriate training member directly or through a pulley provided on the base side, such as the bottom of the cylinder, and allow the user to pull or push the training member, or allow the user to lie down on an appropriate platform. By lying down, lying on your back, or sitting on a trolley, you can perform various training exercises, and the lower end of the spiral spring can be fixed or opened to reduce the load on the user. It can be easily adjusted by operation. In other words, increasing the fixed number will increase the load, and decreasing it will decrease the load.

〔Example〕

Next, an embodiment of the present invention will be described with reference to the drawings.

When the cable 14 is pulled, the lower pulley 7 is pulled toward the upper pulley 10. It is now moving upwards.

Note that the cable 14 includes a pulley 7a, a pulley 10a, and a pulley 7.
b. Since the pulley 10b is looped twice between the upper and lower pulleys 10 and 7 in that order, the spiral springs 6a and 6
It is possible to obtain a length of expansion and contraction that is four times as long as the amount of expansion and contraction of cylinders b and 6c, and a sufficient expansion and contraction stroke can be obtained even at the limited height of the cylinder 4.

s is a stopper provided between the upper pulley 10 and the lower pulley 7 in the cylinder 4 in order to limit the upward movement of the lower pulley 7.

15 is a through hole provided in the lower part of the cylinder 4 facing the locking hole n of the spiral spring attachment bodies 5a, 5b, 5c, and 16 is a hole that can be inserted into and retracted from the locking hole n through the through hole 15 in the lower end. A locking plate 18 consisting of a plate spring having a locking protrusion 17 fixed thereto and the other end fixed to the side wall of the cylinder 4 operates the locking plate 16 to fix or fix the mounting bodies 5a, 5b, 5c. The operating lever 19 for opening is an operating rod attached to the lever, and the operating lever 18 is rotatably attached to a shaft 20 provided in the cylinder 4. In the state shown by the solid line,
The operating lever 18 is located at the upper position, the locking protrusion 17 is in the locking hole n, and the spiral spring mounting body 5 is fixed inside the cylinder 4. In this state, pull the operating lever 18 toward you. , when the lever 18 is rotated 90 degrees around the shaft 20, the operating rod 19 is moved to the locking plate 1.
6, the locking plate 16 is pressed and rotated outward, and the locking projection 17 is separated from the locking hole n and the through hole 15. As a result, the helical spring mounting body 5 is attached to the cylinder 4 It is becoming more open inside.

21 is a connecting ring attached to the tip of the cable 14; 22
T1 is a pulley for leading out a cable attached to the lower part of the base 1 side of the cylinder 4 via a mounting member 23, and T1 is a handle to which a connecting fitting 24 for connecting to the connecting ring 21 is attached to one end via a connecting cable 25. T2 is a training member consisting of a handle H2 to which a connecting fitting 26 for connecting to the connecting ring 21 is attached via a connecting rope 27 passing through the pulley 22, and T2 is a training member consisting of: The connecting fitting 2
4 is connected to a connecting ring 21, which is held by the user to perform various types of training described later, and like T1, T2 is also connected to the connecting ring 21.
6 is used by connecting it to the connecting ring 21, but since this T2 passes the connecting rope 27 through the pulley 22 for leading out the cable, it is different from T1 as will be described later. It is intended for use in different types of training.

The training members T1 and T2 are used for basic training by the user grasping their handles H1 and H2 and pulling or pushing them, and the load during training is , is determined by the number of spiral springs 6 installed in the cylinder 4 that are fixed within the cylinder 4.

That is, as shown in the figure, three spiral springs 6a, 6b, 6c are used for each cylinder 4, and the locking plate 16 is locked in the locking hole n of each mounting body 5a, 5b, 5c. When the training protrusion 17 is inserted and each attachment body is locked, and the training member T1 is pulled, the upper pulley 10 is in the fixed position.
The lower pulley 7 rises as the cable 14 is pulled out, resisting the repulsion of each helical strand and stretching the strands, but since the three helical strands are fixed, all of them are subject to the load. Therefore, the user has to pull the member T1 with a considerable force.
cannot be pulled to be suitable for training.

On the other hand, if the mounting bodies 5a and 5c of the left and right spiral springs 6a and 6c are locked by the locking protrusion 17 and the mounting body 5b of the central spiral spring 6b is used in an open state, the central spiral spring 6b and the mounting body 5b rises together with the lower pulley 7, so the load is approximately 2/2 of the above.
3, and the mounting body 5b of the central spiral spring 6b.
If only the spiral spring 6b is fixed and the other mounting bodies are left open, only the central spiral spring 6b will be loaded.
Spiral springs 6a, 6c and their attachment bodies 5a, 5c
Since the lower pulley 7 rises with the lower pulley 7, the load is approximately 1/3 of that when all the attached bodies are fixed.

Furthermore, in order to efficiently use the training machine of the present invention, the following training members are used.

T3: Bar B to which a connecting fitting 28 is attached via a connecting cable 29.

T4: Two arcuate rods 30 are spaced apart appropriately, and a curved plate 31 bent into an arc is fixed thereon, and a locking member 32 that locks to the upper side of the reinforcing rod 3 is attached to the upper end of the arcuate rod 28. Warped board stand.
