Description

Waist Twist Fitness {CHAIR WITH EXERCISING FEATURE}

The present invention relates to a fitness machine that provides a health effect on the waist by the seat performs the automatic rotation and vertical swing function.

According to Taiwan Patent Publication No. 229389 (Structure of an office chair that combines exercise functions for the waist region) in accordance with the present invention, the design is mainly related to the structure in which the footstool is connected to the seats. The rocking function of the seat body is added to perform a similar rocking action in accordance with the combination of these rotations and rockings to achieve the purpose of the twisting exercise of the waist region. A horizontal guide sheet is formed on the support fastened to the seat and the scaffold, an axial slot is formed in the center portion of the guide sheet, an adjustment screw is inserted into the axial slot, and a knob on the outer exposed side of the adjustment screw. Since it is formed and the nut is coupled to the other side, the induction sheet can be made into a fastening form. Thus, the adjusting screw is idle, and a shaft is also formed on the screw, allowing the shaft to move in the horizontal direction as the adjusting screw rotates, and the upper side of the shaft is engaged with the lower portion of the bearing connecting sheet to be combined with the sheet. . One side of the support is fastened to the pipe in the scaffold, and the other side is provided with a position fixing device. Therefore, when the entire assembly is completed, the office chair is provided with two types of rotations, starting with the footrest and the main body swing, thereby providing an exercise function for the lower back portion, and using the position fixing device on one side of the pipe in the footrest. Simple rotating office chairs are provided.

The shaft pivotally connected to the seat is in an eccentric state with the support, so that the seat can be annularly rotated around the support, whereby the user has a small width relative to the waist by his force when sitting. Twisting can be performed, thus achieving the purpose of waist twisting.

However, when performing a circular rotation with the foot on the ground and seating the buttocks on the seat, not only does the leg get tired in a short time, but when the seat performs a circular rotation, the user's torso only performs horizontal movement. As a result, there is a problem that a continuous circular cyclic friction is caused to the buttock joint, so that the buttock joint is susceptible to movement.

Therefore, the inventors of the present application, by studying the seat structure that can be changed inclined at a constant angle in accordance with the change in the position of the center of gravity of the user's body while the seat body is automatically circular circular trajectory movement and the seat swings up and down The utility model has been completed with sufficient ideas and several tests and tests.

An object of the present invention is to improve the structure of the waist twist fitness machine so that the seat can automatically perform a circular circular track motion, and the seat angle can be inclined in accordance with the change in the position of the center of gravity of the user body.

A scaffold is formed in the lower part of the support, and a motor is fastened to the head of the support. The motor mainly rotates a shaft extending to the head of the support, and an arm is fixed to the rotatable shaft head. In the vertical axial slot, a position limiting screw and a position adjusting shaft are formed, and a screwing hole is formed in the shaft, and the screw can be inserted into the screwing hole to be fastened and connected to the head portion. A member is formed to engage a semi-circular recess in the lower part of the seat, and two or more elastic members are connected between the lower part of the connecting member and the lower part of the seat, and in the completed assembly state, the seat is automatically circularly circulated with the shaft as a support point. It is supposed to work. In addition, when the seat is rotated, the inclination angle of the seat can be changed according to the change in the position of the center of gravity of the user's body.

Hereinafter, with reference to the accompanying drawings will be described in detail a preferred embodiment of the present invention.

As shown in Figure 1 and 2, the present invention relates to a waist twist fitness machine structure. This gym

A support 10, a footrest 11 formed under the support 10, a shaft 12 extending in the axial direction of the head portion of the support, and fixed to the shaft so as to surround the shaft 12. Bevel gear 13,

A motor 20 fixed to the head of the support 10, a worm gear 21 engaged with the bevel gear 13 of the shaft 12 and having an output end portion;

Between the arm 14 of a predetermined length fixed perpendicularly to the head portion of the shaft 12, the axial slot 141 formed at the vertical end of the arm 14, and the axial slot 141 The rotating screw 15 for limiting the position to be formed, the impeller 151 formed on one side of the screw 15, and the handle formed on the outside of the impeller 151 for convenient operation of the adjusting screw 15 ( 152, a reduction motor 153 (see Fig. 4) connected to one side of the screw 15 and capable of automatically controlling the rotation of the screw 15,

A shaft 30 surrounded by an axial slot 141, the upper and lower sides of the shaft is formed with a washer 31 connected to the upper and lower sides of the axial slot 141 to maintain a horizontal plane, the lower portion of the shaft 30 The nut 32 is fastened to each other, and adjusts the fixed or moved state (see FIG. 3) of the shaft 30 according to the tightening degree of the nut 32, and can freely swing the head portion of the shaft 30. The connection member 40 is formed so that

A sheet 50 in which a semicircular recess 51 is formed so as to be engaged with the sphere 41 of the head of the connecting member,

It is composed of a plurality of elastic members 60 formed between the lower portion of the connecting member 40 and the lower portion of the sheet 50.

The principle of operation is as follows. When the motor 20 is operated, the worm gear 21 at the output end is driven to rotate the bevel gear 13 fixed to the shaft 12, and the arm 14 fixed to the head portion of the shaft 12 is synchronized. Since the shaft 30 in the axial slot 141 formed to surround the arm 14 is circularly rotated, the user sitting on the seat 50 can perform the waist twisting movement without applying force. Thus, the effect of promoting blood circulation is obtained.

In addition, the seat 50 may be appropriately inclined according to the change of the center position of the user, thereby reducing damage due to friction of the buttock joint.

Here, the elastic member 60 connected to the lower portion of the connecting member 40 and the lower portion of the sheet 50 is a spring or elastic rubber band having elasticity and the number of connections is at least two or two or more. Pay attention.

In addition, the connecting member 40 formed on the upper side of the shaft 30 and the semicircular recess 51 at the lower portion of the seat 50 have a structure that engages with each other, and is mainly preferred for the tilting angle of the swinging angle of the seat 50. It is just an example. Here, it is only described that the sheet 50 swings up and down, and is not limited to the above structure, and all changes and decorations within the scope of the present invention are within the scope of the present invention.

As shown in FIG. 1, the lower part of the shaft 12 is first axially enclosed and fastened to the adjusting rod 70, and the lower part of the adjusting rod 70 is axially enclosed and fixed to the support 10. In addition, a plurality of position fixing holes 71 are formed in the adjusting rod 70 at regular intervals, and an insertion hole 101 is formed in the support 10 so that the pin 80 is inserted into the insertion hole 101. And the two structures can be fastened by insertion into the one position fixing hole 71. Thereby, the height of the sheet | seat 50 can be adjusted.

According to the present invention, there is provided a waist twist fitness machine structure in which the seat can automatically perform a circular circular track motion, and the seat angle can be inclinedly changed according to the change in the position of the center of gravity of the user's body.
