The present invention relates to a lower body exercise device for a swivel chair, and more specifically, to a coupling device that can be combined or detached by a simple operation of the exercise device equipped with a pressure lever to strengthen the leg muscle strength to the support pillar of the swivel chair widely used for work The pressure lever is installed to be divided into both sides in the range of the shoulder width to perform the lower body exercise suitable for the user while maintaining a stable balance, and also to facilitate the storage after using the exercise equipment to exhibit the function of the swivel chair. It relates to a lower body movement device for a swivel chair.

In general, a rotary chair having a seat plate rotatably installed on an upper portion of a support shaft having a plurality of casters in order to provide convenience for short distance movement and direction change to a worker working in a chair.

Apart from the convenience of the swivel chair, most people who work for a long time in the chair realize the fatigue caused by lack of exercise. Accordingly, the swivel chair can be exercised frequently to recover fatigue while working on the chair. Or technology has been proposed that the chair is equipped with various types of exercise equipment.

The conventional exercise device for attaching a chair of Patent No. 10-1025293 includes a frame fixed to a leg or a seat of a chair, a pedal unit for causing an exercise effect, an eddy current brake, a first speed increasing unit and a second speed increasing unit. It is designed to allow lower body exercise through the act of turning a pedal. It allows users to adjust the exercise load and to compactly configure the size of exercise equipment so that it can be used in a narrow space such as a desk or a table. I would have to.

However, in the case of the exercise device for the chair attached to provide a beneficial effect on the human body through the lower body movement, the frame equipped with each component is always prominently protruded to the outside of the chair, so cumbersome obstacles at times other than exercise There was a problem that interfered with the activity.

Rotating chair legs equipped with the exercise device of Patent No. 10-1204172, which has been proposed as another example of the related art, is configured to be coupled to the bottom of the seat of the rotating chair by installing a step exercise device and a waist rotation exercise device on the rotating chair leg. During the use of the swivel chair, it is configured to move the position of the seat to enable step movement or waist rotation movement from time to time.

The above technique has a problem that the structure and operation are very complicated in the process of disassembling, combining, and modifying the pedestal, and the step movement mechanism and the waist rotation movement mechanism are completely supported by the freely movable chair legs. If you could not lean on a separate object, lose center of gravity or balance while exercising with the equipment, there was a risk of falling and losing your support.

In particular, the conventional exercise equipment as described above can be installed only when a fastening element such as a bolt hole or a shaft hole for fixing the exercise equipment to the leg portion of the chair and the rotating shaft and the seat plate is already used. There was a problem that the installation was extremely limited or impossible.
