Description

DETAILED DESCRIPTION OF THE INVENTION Industrial Field of the Invention The present invention relates to a strength training device.

2. Description of the Related Art In general, as a device for exercising muscle strength, it is customary to raise and lower weights. In particular, a bench press sits on a chaise lounge or lies on its back and grasps the handle, and by moving the handle up and down, the handle makes a circular motion around its pivotal portion, and the weight connected to the handle is raised and lowered. It is a device that exercises by applying weight to the strength of the chest and arms. In this case, the weight is composed of a plurality of weight blocks mounted on the guide column so as to be able to move up and down, and has a weight connector that can be loaded on the handle by selecting an appropriate number of weight blocks. It was connected to the handle.

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention However, according to the above-mentioned conventional example, since the handle and the weight connector were directly connected, it was not possible to adjust the distance between the chair and the handle according to the user. .

Therefore, in view of the above circumstances, the present invention aims to improve a muscle training device so that the distance between the chair and the handle can be adjusted.

Means for Solving the Problems In order to solve the above problems, the present invention supports a weight on a guide rod erected on a base so that the weight can be moved up and down, and a base portion of a handle which is connected to the weight via a weight connecting tool is a base. In a muscular strength training device which is rotatably supported on a table side and grips the handle to move up and down, a screw is screwed at each end of the tubular body to connect the handle and the weight. A muscular strength training device was constructed in which a suspension support was used and both screw screws were rotatably connected to the handle and the weight connecting device by pins.

Effect According to the present invention, since the handle and the weight connecting member are substantially connected by the turnbuckle suspension support, the distance between the handle and the weight connecting device can be expanded or contracted by rotating the suspension support. This allows the distance between the handle grip and the bench to be changed and adjusted, while the screw screw is pin-coupled to the handle and weight connector, respectively, so the circular motion of the handle and the linear motion of the weight connector can be buffered, and the weight can be reduced. Move up and down smoothly.

Embodiment An embodiment of the present invention will be described below with reference to the drawings. First
Figure is a side view, Figure 2 is a front view, Figure 3 is a plan view,
In the figure, 1 is a base, 2 is a portal frame standing vertically on the base 1, and 3 is bearings 5, 5 fixed to backstays 4, 4 supporting the portal frame 2. 5 is a shaft pivotally supported in a horizontal position, 6 is a handle support rod whose base is rotatably supported on the shaft 3, 7 is a two-handed handle connected to the handle support rod 6, and 8 is a handle support rod 6 Pins to the bracket 9 and weight connector 10 fixed to the
11, 12 is a suspending tool connected so as to be rotatable, 13 is a weight formed by a plurality of weight blocks having a predetermined weight, 14, 14
Is a guide rod for guiding the lifting and lowering of the weight 13, the upper end of which is connected to the gate frame 2 and the lower end of which is connected to the base 1. The weight connecting tool 10 can select and connect a desired number of weight blocks. The hanging fixture 8 is shown in FIG. 4 and FIG.
As shown in the drawing, eyebolt-shaped screw screws 17, 17 are respectively screwed to both ends of a tubular body 16 having a predetermined length in which an elongated hole 15 is formed in the axial direction so as to be axially movable. Is a turnbuckle, and a stopper 18 for preventing the screw from coming off is attached to an inner end portion of the screw screw 17. 17
a is a pin insertion hole, and 17b is a threaded portion. A pointer portion 19 is formed on one of the stoppers 18 so as to face the elongated hole 15, and a graduation 20 indexed by the pointer portion 19 is attached to the elongated hole 15. The screw portion of the screw screw 17 has a so-called multiple thread (multiple) screw structure having a plurality of starting ends, so that the axial movement amount can be increased with a small number of rotations. Reference numeral 21 is a bench for the user to sit or lie down, and its support base 22 is connected to the base 1.

Therefore, to explain the operation of the above-described embodiment, a person who exercises muscle strength selects a desired number of weight blocks and connects them to the weight connector 10 to determine the load weight,
Adjust the handle 7 to your preferred height. That is, the claw screws 17 and 17 are moved forward and backward from the cylindrical body 16 by rotating the suspension support 8 about its axis. The moving amount of the screw screw 17 moving back and forth from the cylinder 16 is the pointer portion 19
Can be seen from the long hole 15 as a guide. Thus, after adjusting the distance between the handle 7 and the bench 21, when the grips 7a, 7a of the handle 7 are grasped by both hands and the handle 7 is lifted upward, the handle 7 makes a circular motion around the shaft 3 and hangs. The weight connecting tool 10 is pulled up via the supporting tool 8, the weight block connected to the weight connecting tool 10 rises, and the weight thereof is loaded on the handle 7. At this time, the screw 8 of the hanging fixture 8 has pins 11,
Since the handle 7 and the weight connector 10 are rotatably connected to each other at 12, it is easy to change the direction of the force between the circular movement of the handle 7 and the linear movement of the weight 13, so that the weight 13 is guided. Smoothly guided up and down without resisting the rods 14,14.

Effect of the Invention According to the present invention described above, since the handle and the weight connector are connected by the turnbuckle type suspension support, the distance between the handle and the bench can be continuously changed and adjusted, that is, finely adjusted. In addition to being adjustable, the screw screws that are screwed into the tubular body of the suspension support are pin-connected to the handle and the weight connector, respectively, so that they can rotate, so that there is a buffer between the circular movement of the handle and the linear movement of the weight. Because you can
The weight can move up and down smoothly with respect to the guide rod.
