Description

The present invention relates to a field of a twist stepper that can be used as a stepper mainly used for exercising at home, and can simultaneously perform an up / down stepping motion and a twisting motion of twisting the upper body and the upper stepping motion.

  A conventional stepping exerciser is a device that steps on the pedal plate alternately in the vertical direction while riding on a pair of left and right pedal plates against the urging force of the cylinder.

Furthermore, the exercise of thighs and buttocks can be performed by swinging the pair of pedal plates only in an oblique state, assuming that the exercise is not sufficient only by the pair of pedal plates of the stepping exerciser alternately stepping up and down. There is an oblique swing stepper.
Utility model registration No. 3108410

  The problem to be solved by the present invention is that a pair of pedal plates constituting the twist stepper of the present invention is set at a predetermined angle with the central portion of the fixed portion on which the pedal plate is placed as the axis according to the user's preference. We have developed a twist stepper that allows you to exercise by adding a twist function that moves the pedal plate of the stepping part and the stepping part to the left and right respectively so that it can rotate.

  Further, the problem to be solved by the present invention is to fix the pedal when the user wants to perform an effective aerobic exercise by stopping the twisting twisting movement as described above and stepping on so-called walking. The rotation of the part is stopped and can be switched by simple means.

According to a first aspect of the present invention, there is provided a cylinder, a support arm, and a connecting rod that are perpendicular to the left and right sides of the connecting portion that bonds the legs facing each other at a predetermined interval. One end of each of the cylinders, and the other end of the cylinder and the other end of the support arm are connected to each other, and an adjusting rod for adjusting the height of the pair of symmetrical support arms by a regulator is provided. In a twist stepper that is connected to a support arm, a fixing portion with a stopper is symmetrically fixed to the other end of the pair of support arms, and a pedal is attached to the pair of symmetrical fixing portions with a stopper, respectively.
The pedal fixing portion for attaching the pedal is pivotally attached above the fixing portion with the stopper so as to rotate by a predetermined angle to the center portion of the pair of symmetrical fixing portions with the stopper and not easily detached. In addition, the twist fixing stepper is characterized in that the pedal fixing portion and the fixing portion with stopper are fixed through a connecting body, or the connecting body is detached and the pedal fixing portion is rotated by a predetermined angle. .

Further, the invention according to claim 2 of the present invention is the twist stepper characterized in that the pedal fixing portion rotates at an angle of about 30 to 40 degrees with respect to the stopper-equipped fixing portion.

According to a third aspect of the present invention, the fixing means for fixing the stopper-fixed portion to the pedal-fixing portion includes a shaft mounting portion that pivotally mounts the stopper-fixed portion, and one end portion of the stopper-fixed portion. A through hole is formed between the fixed portion with the stopper and the bottom portion of the pedal fixing portion that overlaps with the fixed portion with the stopper, and a hole portion that matches the through hole is formed, and the fixed portion with the stopper and the pedal fixing portion are The twist stepper is characterized in that the connection body is screwed and connected to the through hole and the hole.

According to the first aspect of the present invention, the cylinder and one end of the support arm are connected at right angles to both the left and right sides of the connecting portion that bonds the opposing leg portions with a predetermined interval, and the other end of the cylinder And the support arm and the other end of the connecting rod are connected to each other, and an adjusting rod for adjusting the height of the symmetrical pair of supporting arms by a regulator is connected to the pair of supporting arms, and the pair of supporting arms. In the twist stepper, in which a fixed portion with a stopper is symmetrically fixed to the other end of the pair, and a pedal is attached to the pair of symmetrical fixed portions with a stopper, respectively, the central portion of the pair of symmetrical fixed portions with a stopper The pedal fixing part for attaching the pedal is pivotally mounted above the fixing part with the stopper so that the pedal fixing part does not easily disengage, and the pedal fixing part and the fixing part with the stopper are Contact Since it is a twist stepper that is fixed through the body or that disengages the connecting body and rotates the pedal fixing portion by a predetermined angle, both the left and right sides resist the urging force of the cylinder by tightening the connecting body. By rotating the pedal to the left and right, the user can easily add a twisting motion to the user's waist while stepping, and train the leg muscles by the above-mentioned vertical stepping motion and twisting motion. It has the effect of remarkably tightening the lower body, such as the waist and legs.

Furthermore, the present invention has an advantage that if the connecting body is tightened, only a stepping motion can be performed alternately in an upward and downward direction.

In addition, since the present invention has a very simple structure for attaching and detaching the connection body, the production cost is low.

Further, the invention according to claim 2 is the twist stepper in which the angle at which the pedal fixing portion rotates with respect to the fixing portion with the stopper is about 30 to 40 degrees. Have.

According to a third aspect of the present invention, the fixing means between the fixing portion with stopper and the pedal fixing portion penetrates between a shaft mounting portion that is pivotally attached to the fixing portion with stopper and one end portion of the fixing portion with stopper. Forming a hole that matches the through hole in the bottom surface of the pedal fixing portion that overlaps with the fixing portion with the stopper, and superimposing the fixing portion with the stopper and the pedal fixing portion to form the hole; Since it is a twist stepper in which the connecting body is screwed and connected to the through hole and the hole portion, it has the same effect as the effect of the device of claim 1 or claim 2.
