Description

Sliding Exercise Equipment

The present invention relates to a body correcting exercise device capable of exercising the lower back, and more particularly, with the help of an auxiliary device, the pelvis and the lower body are mainly exercised without moving the legs and upper body parts of the shoulder, and the durability of the body is improved. It is about corrective exercise equipment.

As an exercise device in which the sliding reciprocating movement of the buttock support can be made repeatedly, the user can comfortably exercise the waist by lying down with the help of an auxiliary device. Such an exercise device is composed of a pedestal that reciprocates by sliding and a drive motor disposed under the pedestal to slide the pedestal. This exercise device has a sliding bar that is vertically coupled to the pedestal and has a sliding slot formed long in the vertical direction, has a protrusion that protrudes from a rotating plane and is inserted into the sliding slot, and has a rotating wheel that is rotated by a driving motor. As the rotating wheel rotates, the protrusion moves along the sliding slot and acts as a switching pin to change the direction of motion, and pushes or pulls the sliding bar in the longitudinal direction to move it.

However, since the sliding slot is vertically disposed with respect to the pedestal, the protrusion serving as the switching pin is moved along the sliding slot by the rotation of the rotating wheel, and the pedestal coupled with the sliding bar is slid in the horizontal sliding direction. Since the height of the exercise equipment is increased by this arrangement, the user may feel inconvenience.

In addition, in this case, when the protrusion pushes or pulls the sliding bar from the sliding slot far from the pedestal, the driving load is concentrated on the coupling portion of the pedestal and the sliding bar, thereby reducing durability.

6 (a) the switching pin 61 is located on the upper side of the switching slot 62, the height adjustment protrusion 611 is located in the high position of the height adjustment long hole (621). Accordingly, the slider 50 is located at the lowered position.

6 (b) according to the rotational driving of the driving motor 33, the idle gear 70 transmits the driving force to the crank pinion 34 and rotates the switching pin 61 of the crank disk 20 in a counterclockwise direction. The pin 61 pushes the left side of the switching slot 62 to push the slider 50 to the left. The switching pin 61 is moved downward along the switching slot 62 and located in the center of the switching slot 62 . Since the height adjustment long hole 621 has a shape that is lowered toward the central region from the upper side of the switching slot 62 , the height adjustment protrusion 611 is located at a lower position of the height adjustment long hole 621 . Accordingly, the slider 50 is positioned at an elevated high position.

Since the height adjustment long hole 621 has a shape that is lowered toward the upper and lower sides in the central region of the switching slot 62, the height adjustment protrusion 611 is located at a higher position of the height adjustment long hole 621 and then is located again at a lower place. Accordingly, the slider 50 is positioned at a lowered position and then at a higher higher position.

7 (b) as the driving motor 33 is continuously driven to rotate, the idle gear 70 transmits the driving force to the crank pinion 34 to rotate the switching pin 61 of the crank disc 20 counterclockwise. When this is done, the switching pin 61 pushes the left side of the switching slot 62 to push the slider 50 to the left. The switching pin 61 is moved upward along the switching slot 62 and located above the switching slot 62 . Since the height adjustment long hole 621 has a shape that increases toward the upper side in the central region of the switching slot 62 , the height adjustment protrusion 611 is located at a high place of the height adjustment long hole 621 . Accordingly, the slider 50 is located at the lowered position.

Modified embodiments other than the above embodiments will be described.

The switching pin 61 protrudes from the crank disk 20 and is integrally formed, and may be formed of a protruding part and a rotating part rotated with respect to the protruding part. Thereby, a frictional force is not generated while the rotating part moves while pushing the switching slot 62, so that the load is reduced.

When the height adjustment long hole 621 is formed so that the height decreases or increases from one side to the other side of the switching slot 62 area, the slider 50 slides in the horizontal direction while the pedestal 90 is inclined and then becomes horizontal. can be repeated.

In the above, the shape of the conversion slot 62 is formed in a long long hole shape. Unlike this, it has an elliptical shape with a large curvature and is detachably coupled to the inside of the conversion slot 62 to change to an oval shape with a small curvature. It may further have a change member. Accordingly, the sliding range of the slider 50 can be adjusted.

Due to the above body correcting exercise device (1), since the plate surface of the crank disk 20 is arranged in the horizontal direction, the height of the exercise device 1 can be lowered, and the plate surface of the crank disk 20 is arranged in the horizontal direction. In this state, since the rotational motion of the crank disc 20 is converted into a reciprocating sliding motion in the horizontal sliding direction, it is possible to reduce the concentration of the driving load for the sliding motion. Due to the crank shifting part 60, the shifting pin 61 inserted into the shifting slot 62 is rotated according to the rotation of the crank disc 20 in a state in which the plate surface of the crank disc 20 is arranged in the horizontal direction, and the slider ( 50) can slide and move along the sliding guide (40). Since the driving motor 33 region and the crank disk 20 region do not overlap, the height of the exercise device 1 can be lowered. The positions of the crank disc 20 and the driving motor 33 may be adjusted due to the at least one idle gear 70 . The sliding guides 40 are provided as a pair parallel to each other so that the horizontal sliding movement of the slider 50 may be stable.
