[0003]

[Problems to be solved by the invention]

 However, there is room for improvement in the operation and folding storage of the conventional walking and leg stepping training machine, that is, when the swing arm 13 swings left and right, Since the distance from the rod 11 is too short, there is a possibility that the members may friction with each other and hinder the operation. Further, in order for the pedal bar 16 to achieve the purpose of the leg stepping motion, the pedal bar 16 must be pivoted around an intermediate portion of the pedal bar 16, and the vertical rod 12 itself is used as a pivoting member, and a screw is formed on the side surface. Since the hole 121 is provided to support the pedal bar 16, the material is wasted, the number of assembly members is large, the operation is mutually restricted, and the structural design for folding is not easy. . Furthermore, when folding, only the pedal bar 16 and the rear rod 18 can be folded, and the change in volume that can be reduced is limited.

The present invention has been made in consideration of the above-described problems of the related art, and has as its object to provide a training machine for both walking and stepping, which has simple members and can be quickly and compactly folded.

[Embodiment of the invention]

 Hereinafter, the present invention will be specifically described based on embodiments, but the present invention is not limited to only this example. As shown in FIGS. 1 to 3, the walking and leg stepping training machine of the present invention mainly has a front rod 21 on the front side of the body 20, and can swing right and left on the front upper end surface of the front rod 21. A pivoting arm 22 is pivotally mounted. The pivoting arm 22 has a substantially T-shape, and its lower end is fixed to the front rod 21 by a tightening screw 221. The body 20 has the upper ends of the front swinging rods 23, 23 and the rear swinging rods 24, 24 axially in contact with the upper side, respectively. The pivoting front swinging rod 23 and the rear swinging rod 24 can swing back and forth in parallel in conjunction with the pedal bar 25, thereby providing a walking movement pattern. Further, the pedal bar 25 is pivotally fixed to the fuselage 20 by the bolt 251 at the intermediate portion of the pedal bar 25, so that the seesaw movement of both ends of the pedal bar 25 is formed, thereby providing a stepping movement pattern.

The improvements of the present invention are as follows. The fuselage 20 is provided with a socket seat 211 of a diagonally rearwardly downwardly angled square pipe at a predetermined height on the rear side surface of the front rod 21, and another downwardly directed square pipe at a predetermined position on the rear side of the fuselage 20. A socket seat 212 is formed, and the rear rod 26 can be inserted into the socket seat 211 or another socket seat 212, and each of the socket seats 211, 212 can be fixedly fixed to the rear rod 26 by a fixing screw 213. The front rod 21 has a vertically elongated hole 214 at a predetermined height on both sides and a through hole 241 at a predetermined position at the lower end of the rear swinging rod 24.

The pedal bar 25 is provided with an ear seat 252 at the bottom of the front end thereof, and is used to pivotally connect the folded pedal bar 25 and the lower end of the rear swing rod 24.

The overhang arm 30 has a substantially T-shape, and is pivotally attached to the lower end of the front rod 21 so as to freely move up and down, and a lateral yoke 31 is positioned at the end thereof. A screw hole 311 is provided, and when the overhang arm 30 is turned downward, the bolt 251 is screwed into the screw holes 311 at both ends of the yoke 31 to turn the overhang arm 30 upward. When the bolt 251 is passed through the through hole 241 of the rear swinging rod 24 and screwed into the screw hole 311 of the yoke 31, the rear swinging rod 24 is fixed and does not move, and the intermediate portion of the pedal bar 25 is pivotally supported. Thus, the pedal bar 25 can perform a seesaw movement at both ends.

The sliding seat 40 is provided at a predetermined portion of the front rod 21 so as to be able to slide up and down, as can be seen simultaneously with reference to FIG. 4, and the sliding seat 40 has a pair of ear plates 41 at its rear end. The fastening member 42 formed and attached to a through hole (not shown) provided in the both ear plates 41 is passed through the long hole 214 of the front rod 21, and the handle 421 provided in the fastening member 42 is rotated. Then, the sliding seat 40 can be fixed to the front rod 21 so that the sliding seat 40 can slide up and down along the elongated hole 214. The sliding seat 40 has a fixing hole 43 formed in the front end face thereof, and a tightening screw 221 screwed into the lower end of the swing arm 22 can be screwed into the sliding seat 40. The sliding seat 40 is moved upward to be positioned at the upper extreme point. The moving arm 22 can be fixed to the slide seat 40 by the tightening screw 221. Further, by loosening and removing the tightening screw 221 and moving the slide seat 40 downward to the lower pole point, an appropriate gap can be formed between the swing arm 22 and the front rod 21.

Next, the operation of each member and the effects that can be achieved will be described. When performing a walking movement, as shown in FIGS. 2 and 3, the sliding seat 40 is moved upward and adjusted to be positioned at the upper extreme point, and the swing arm 22 is screwed into the sliding seat 40 with the tightening screw 221. The swing arm 22 is fixed so as to be inoperable, and the front swing rod 23, the rear swing rod 24, and the pedal bar 25 form a link. Both feet can be reciprocated forward and backward by stepping on the upper surface of the pedal bar 25. Exercise effects can be achieved.

4 and 5, when the leg stepping motion is performed, if the tightening screw 221 fixing the swing arm 22 is loosened and removed, the swing arm 22 swings freely from side to side. The sliding seat 40 slides down to avoid interference with the swing arm 22, and the fastening screw 221 is screwed into the fixing hole 43 of the sliding seat 40 again. Next, the bolts 251 screwed to both ends of the overhang arm 30 are loosened and removed, and the overhang arm 30 is turned upward so as not to interfere with the pedal bar 25, and then loosened after the overhang arm 30 reaches a predetermined position. When the removed bolt 251 is inserted through the through hole 241 of the rear swinging rod 24 and screwed into the screw holes 311 at both ends of the projecting arm 30 again, the rear swinging rod 24 is fixed to the projecting arm 30 and does not move. The front and rear ends of the pedal bar 25 can swing up and down in a seesaw motion manner with the ear seat 253 at the intermediate position as a fulcrum, and both feet can be stepped on both pedal bars 25 to perform a leg stepping motion.

When the fuselage 20 is folded without being used, as shown in FIG. 6, the pivot pin 243 between the ear seat 253 at the middle position of the pedal bar and the pivotally connected end 242 of the rear swinging rod 24 is removed. The pedal bar 25 is folded upward about the pivot point with the front swinging rod 23 as an axis, and the rear swinging rod 24 is brought close to the folded pedal bar 25, and the pivotally connected end 242 of the rear swinging rod 24 is connected to the pedal bar 25. It is positioned in the bottom ear seat 252, and the pivot pin 243 that was previously removed is inserted and fixed. At this time, the rear rod 26, one end of which is assembled obliquely into the socket seat 211 of the front rod 21, is disassembled by loosening the fixing screw 213 at this time, and another socket seat at the upper end of the body 20 is removed. One end of the rear rod 26 is inserted into 212, and the fixing screw 213 that has been loosened and removed is screwed to hold the rear rod 26 in an upright state. Subsequently, the first screws 271 of both handles 27 fixed to the upper end side of the front swinging rod 23 are loosened and removed, and the handles 27, 27 are turned 180 degrees downward with the second screw 272 as a fulcrum. The leaning cushion 28, which is folded in the body 20 and the support rod 281 is fixed to the round pipe 29 behind the fuselage 20 by the screw 282, loosens the screw 282 and pulls out the leaning cushion 28. If the support rod 281 is screwed into the lower end of the round pipe 29 and the cushion 28 is folded inside the fuselage 20, the volume of the folded fuselage 20 is greatly reduced. can do.

Therefore, the training machine for both walking and stepping on the leg according to the present invention can be selected in combination with the connecting form of interlocking the pedal bar 25 using the front swinging rod 23 and the rear swinging rod 24 and the overhanging arm 30. From the configuration in which the rear swinging rod 24 is fixed or free, the movement of both types of walking and stepping on the hips and legs can be achieved in the same manner as in the above-described conventional example, while the most important points of improvement are the members. This is to simplify and reduce the total volume of the folded body. The front rod 21 is simply formed on the body 20 and is replaced with the overhanging arm 30 without providing a standing rod as compared with the conventional example. The weight and the number of assembly members can be reduced, the cost can be reduced, and each rod can be folded into a smaller volume when stored. In addition, since the movable sliding seat 40 is used as an intermediate fixing medium for the combination of the swing arm 22 and the front rod 21, the sliding seat 40 faces downward when the swing arm 22 swings left and right. Sliding movement can be made so as not to interfere with the operation of the swing arm 22.
