When described in more detail on the basis of the accompanying drawings the preferred embodiment of the present invention.

1 and 2, the present invention includes a leg movement means (10).

The leg movement means 10 is provided with a pedestal 11 and a pair of supports 12 and 12 'standing up on both sides of the pedestal 11.

In addition, the wheel case 13 is fixedly installed between the pair of supports 12 and 12 ', and the wheel case 14 is provided in the wheel case 13 to be idle.

In addition, a pair of pedal cranks (15, 15 ') having a pedal (15a) on both sides of the wheel member 14, respectively. The pedal cranks 15 and 15 'are installed to be exposed to the outside of the pair of supports 12 and 12' for rotation.

Accordingly, when the pedal 15a is stepped and rotated, the pedal cranks 15 and 15 'are rotated so that the wheel member 14 is rotated. Since the wheel member 14 is to have a relatively heavy weight, it is possible to exercise the leg in the same feeling as riding a real bike.

And the present invention is provided with a wheel pressing means 20 for forcibly controlling the rotation of the wheel member (14).

As shown in FIG. 3, the wheel pressing means 20 includes a nut member 21 fixed to the wheel case 13, an adjustment bolt 22 fastened to the nut member 21, and the adjustment bolt 22. End engaging portion 23 of the) is made by the pressing member 25 having a lining (25a) is caught in the idle groove 24 and movable in the vertical direction and in contact with the wheel member (14).

Therefore, when the adjusting bolt 22 is tightened, the pressing member 25 is moved toward the wheel member 14 to pressurize the wheel member 14, thereby forcibly controlling the rotation of the adjusting member 22, and vice versa. When released, the pressing force of the pressing member 25, which has been pressing the wheel member 14 is released, and the wheel member 14 is in a state capable of smoothly rotating.

Therefore, by the act of tightening and loosening the adjusting bolt 22, the strength of the pressing force that the pressing member 25 presses the wheel member 14 is adjusted.

At this time, when the pressing force of the wheel member 14 is hard, the wheel member 14 does not turn well, and when the pressing force is relatively low, the wheel member 14 turns well.

Therefore, when the wheel member 14 is adjusted poorly, it is difficult to rotate the pedal cranks 15 and 15 'and conversely, when the wheel member 14 is adjusted to rotate well, the pedal cranks 15 and 15' are adjusted. As it takes relatively less power to rotate the leg exerciser, the leg exerciser adjusts to a state suitable for him to exercise the leg.

1 and 4, the concealed groove portions 16 and 16 'are provided on both sides of the pedestal 11, and the hinge shafts 17 are provided on the concealed groove portions 16 and 16'. A pair of auxiliary pedestals 18 and 18 'which are pivoted outwardly to the center are inserted.

Therefore, the auxiliary bases 18 and 18 'are inserted into the concealed groove portions 16 and 16' when they are not normally used, so that they are stored in the concealed state and the concealed grooves 16 and 16 'are used when the instrument is used. The auxiliary pedestals 18 and 18 'are withdrawn and used.

Since the auxiliary pedestals 18 and 18 'have a handle portion 18a which is hooked to the side of the pedestal 11 on one side of the tip portion, the tip portions of the auxiliary pedestals 18 and 18' are formed using the handle portion 18a. When pulled outward, the front end portions of the auxiliary bases 18 and 18 'are rotated outwardly about the hinge shaft 17 and are drawn out from the concealed grooves 16 and 16'.

Therefore, the auxiliary pedestals 18 and 18 'play a supporting role as a state of being unfolded to both sides of the pedestal 11 as shown in the solid line of FIG. 4.

Therefore, in the present invention, since the supporting area is widened by the auxiliary pedestals 18 and 18 ', the leg movement means 10 can be stably moved without falling down during leg movement.

In other words, the mechanism that rotates the pedal crank (15, 15 ') by the foot movement of the mechanism should be wider to prevent the device from falling down. do.

However, in the present invention, by making the pedestal 11 small, the storage can be easily and conveniently moved. And only by using the widened support area will be able to use the leg movement in a stable state.

And leg exercise means 10 of the present invention is to exercise the leg in a seated state on the chair.

Therefore, take the leg exercise means (10), which is stored or stored in any place in the room, spread the auxiliary support (18, 18 ') and then sit on the chair to exercise the leg.

Therefore, the present invention makes it possible to easily touch the leg movement wherever the chair is provided, in particular, there is an advantage that can perform other actions while doing the leg movement.

In order to help the understanding of the present invention, the former leg exercise equipment is difficult or impossible to exercise the leg while doing other activities except when exercising the leg while watching TV, the present invention is always a lack of exercise students In the case of sitting comfortably in the chair while watching a book to exercise the leg, the elderly can also easily exercise the leg while sitting comfortably in the chair.

In addition, it is possible to use it stably by increasing the support area only when it is used, so that the volume can be made smaller when not in use. Will be done.

And the present invention may be used by drawing the leg movement means 10 under the seating portion 2 of the chair 1 as shown in FIG. In this case, since the leg movement means 10 is the same as described above, detailed description thereof will be omitted.

Therefore, referring to FIGS. 6 to 8, the pair of rails 30 are fixedly installed between the pair of chair legs 3, respectively. Reference numeral 32 denotes a fixing member 32 for fixing to the chair leg 3.

And it is provided with a moving member 40 which is guided along the rail 20 to move out of the chair leg (3).

The rail 30 and the moving member 40 are not necessarily provided only in the form shown in the drawings, and in some cases, the rail may have a circular rod and the moving member may have a ring shape that moves along the circular rod.

Therefore, the base 11 of the leg movement means 10 is installed on the moving member 40 and configured to be moved at the same time.

At this time, the pedestal 11 may be fixed on the movable member 40, or as shown in FIG. 8, the movable member 40 is moved along the rail 30 toward the seating part 2 and then the leg. Lifting the line side of the exercise means 10 in the upper direction may be a leg movement.

When the side of the leg movement means 10 is lifted in the upper direction to perform the leg movement, since the leg movement means 10 itself is inclined, the backrest is inclined at an angle so that the leg movement can be performed in a more comfortable state.

In addition, children with short legs or the elderly can make exercise in the legs more comfortable.

Accordingly, referring to FIG. 9, the top and bottom links 50 and 50 of the moving member 40 and the pedestal 11 have respective upper and lower links 50 and 50 which are diffracted along the link shaft 51. And connected to 52.

The upper link 50 has a deodorant piece (50a) that is caught on the lower link (50 ') on one side.

In addition, the rear end of the pedestal 11 is configured to be connected to the support member 53 and the hinge shaft 54 fixed to the moving member 40.

Therefore, the leg movement means 10 is normally concealed under the seating portion 2 of the chair 1 as shown in FIG. 5. In this case, the upper and lower links 50 and 50 'are folded as shown in FIG.

And if you want to exercise the leg, and withdraw the leg movement means 10, after lifting the side portion of the leg movement means 10 upwards, as shown in (b) of FIG. 11) is rotated so that the front end is lifted in the upper direction, the upper and lower links 50, 50 'are diffracted to be unfolded in a straight shape.

When the state becomes in the above state, even when the leg movement means 10 held by the hand, the upper and lower links 50, 50 'is slightly bent in the state that the anti-fragment piece 50a of the upper link 50 is the lower link (50 ') Since the pedestal 11 is not lowered spontaneously, the leg movement means 10 is able to perform the leg movement in the inclined state as shown in FIG.

And when the leg movement is completed, the upper and lower links (50, 50 ') that are extended are pushed inward by pressing the middle part connected to the connecting shaft (52) by using a toe or a separate tool, and the upper and lower links ( 50, 50 ') is folded (refer to the imaginary line in FIG. 8) and the pedestal 11 is lowered toward the moving member 40. When the leg movement means 10 is pushed in this state, the seat 2 is again underneath. Moved to the outside of the leg movement means 10 is concealed invisible to the naked eye.

At this time, as shown in FIG. 10, the moving member 40 is stopped by the engaging pieces 41 at both ends of the leading end by being caught by the stopper 31 at the leading end of the rail 30, and on the contrary, the moving member 40 is moved forward. In the case of moving to the stopper 31 of the rail 30 is stopped by the engaging piece 41 at the rear end of the moving member 40 is stopped while preventing the moving member 40 is separated. The stop means of the moving member 40 by the stopper 31 and the engaging pieces 41 and 41 'is one embodiment, and other types of stop means may be used in some cases.

Therefore, in the present invention, the leg movement means 10 is normally concealed under the seating portion 2 of the chair 1, and the leg movement means 10 can be taken out and used only during the leg movement.

Therefore, when the present invention is used in a means of transportation such as a passenger plane, a highway bus, a celebrity vehicle, etc., where the activity space is narrow, not only the leg movement can be performed during a long trip, but also the leg movement comfortably in the chair 1. You can sit and do leg exercises while doing other activities such as watching books or watching movies.

And the former leg exercise equipment was not able to exercise the leg comfortably, but the present invention allows the comfortable sitting on the chair (1) to exercise the leg, so that the elderly and comfortable in a place such as a social welfare center or senior center Will be able to exercise legs in.
