Description

[Detailed description of the invention]

[0001]

[Industrial applications]

 The present invention relates to a leg-strengthening exercise device for strengthening legs and relieving muscle fatigue of legs, waist, neck and back.

[0002]

[Prior art]

 Recently, as health consciousness has increased, various small exercise equipment that can be easily used at home has been proposed. Among them, as a training device for strengthening and maintaining leg strength, which is the most important no matter how old a person is, a leg strength called a “stepper” that performs stepping exercises with both feet on different steps There are reinforcement devices.

[0003] Normally, this stepper is configured such that compression coil springs are vertically attached like hopping to the lower surfaces of two parallel left and right parallel treads (steps) on which both soles whose base ends are pivotally supported, respectively. The tip of the foot is urged upward, and the feet are placed on both treads with both toes pointing toward the base end, and the left and right treads are alternately opposed to the spring without releasing both feet from the treads. The stepping motion is performed as if stomping on the foot.However, with this conventional device, the impact is large when stepping on one foot with the entire weight applied, and it tends to be unstable when performing the stepping motion. The burden on the legs was heavy.

[0004] Thus, a device using a hydraulic cylinder as a means for further assisting the impact instead of the spring has been proposed recently, but it is expensive and cannot be provided at low cost.

[0005]

[Problems to be solved by the invention]

 Although the present invention uses a compression coil spring, it can perform the same smooth stepping operation as with a hydraulic cylinder, does not apply excessive impact to the legs, and raises the tread plate at a predetermined angle. This is a proposal for a stretching and leg strengthening exercise device that can also perform stretching exercises that can relieve tire fatigue, lower back pain, muscle fatigue such as neck and back stiffness by changing the direction of the foot by fixing it to It is.

[0006]

[Means for Solving the Problems]

 That is, in the present invention, the bases of two parallel left and right treads, which are large enough to place the entire sole, are attached to a support shaft which is inserted into a support frame provided on the rear end of the base. A compression coil spring is interposed between the lower surfaces of both treads and the base to urge the treads in a diagonally upward turning state. At the middle part of the support column, a seesaw rod that is rotatably supported by a support shaft that is inserted and fixed in parallel with both tread plates and that can rotate and abut on the lower surfaces of both tread plates is attached. A plurality of holes parallel to the support frame are provided above and below the support frame, and a lock pin that is in contact with the lower surfaces of the tread plates is inserted into the holes so that the tread plates can be supported at a predetermined stopping angle. It is related to stretching and leg strengthening exercise equipment characterized by That. Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[0007]

[Embodiment of the invention]

 1 is a perspective view showing an example of the present invention, FIG. 2 is a side view thereof, FIG. 3 is a plan view thereof, and FIGS. 4 to 5 are explanatory views showing different uses of the present invention.

In the drawing, reference numeral 1 denotes a base having a substantially H-shape in plan view, and a support frame 2 having a length substantially equal to the length of the base 1a is formed on one of the base bars 1a which are parallel to each other and constitute the base 1. Fixed. Numeral 3 is a pair of left and right treads 3a and 3b, which are parallel to each other at an appropriate distance and are large enough to hold the entire sole of a foot 7 to 10 cm wide and about 30 cm long. The end is pivotally supported by a support shaft 4 that is inserted in the middle of the support frame 2 so as to be parallel to the base rod 1a, and is configured to be vertically turnable.

Reference numeral 5 denotes an inner / outer double cylinder having a cylindrical shape slidable relative to each other with an end 7 mounted on a mounting bracket 6 vertically fixed to the lower surface of the intermediate portion of each of the two tread plates 3a and 3b, with the openings facing each other. The compression coil spring 8 is inserted into the cylindrical body 5 to urge the cylindrical body 5 in the extending direction. The other end of the cylindrical body 5 is inserted into an intermediate portion of the connecting rod 1b, which connects the parallel base rods 1a constituting the base 1, toward the support frame 2 side. The treads 3a and 3b are urged to pivot obliquely upward around the support shaft 4 by the extension of the cylindrical body 5 having the spring 8 therein.

Reference numeral 10 denotes a column standing upright on the upper surface of the connecting rod 1b of the base 1 between the two treads 3a and 3b. The column 10 extends parallel to the support frame 2 from an intermediate portion of the column 10 upward. When the foot is placed on both treads 3a, 3b, the right and left treads 3a, 3a, at both ends of the treads 3a, 3b are inserted. 3b can be supported and fixed at a predetermined turning angle (for example, an elevation angle of 15 °, 20 °, 25 °, 30 °, etc.).

Reference numeral 13 denotes an intermediate portion which is supported by a support shaft 14 attached to the intermediate portion of the column 10 slightly below and in parallel with the tread plates 3, and is rotatable vertically in a plane orthogonal to the tread plates 3. A cushion pad 15 made of rubber or the like is fixed on the upper surface of both ends of the seesaw 13 at the contact position with the lower surface of the tread plates 3, and if weight is applied to one of the tread plates 3a and 3b, the seesaw rod 13 When the same side is pressed downward, the other end of the rod 13 turns upward about the shaft 14 by the downward turning distance, forcibly and smoothly pushing up the other tread plate.

The upper surfaces of the left and right tread plates 3a and 3b are formed with uneven surfaces to prevent slippage, and cushion pads 16 are fixed to the lower surfaces of the tip portions. An elastic plate 17 such as a rubber plate is attached to an upper portion of the front surface of the support frame 2, and supports the heel when performing a stretching exercise with the toes placed on the front of the tread plates 3a and 3b. Protects frame 2 from injury.

When the leg is to be trained with this device, as shown in FIG. 4, both feet are placed on the corresponding treads 3a and 3b, and the toes are directed toward the support frame 2 of the tread 3 base. The force is alternately and strongly applied against the spring 8 so as to step on the tread plate 3 to perform the stepping motion without leaving the soles of the tread plates 3a and 3b.

Thus, if one of the right and left treads 3a or 3b is stepped on, the other tread is turned upward by the push-up action of the seesaw rod 13 in combination with the repulsion of the spring 8, and the two treads 3a, 3b Can smoothly follow the weight shift to the left and right due to the stepping exercise, and can strengthen the legs without applying excessive impact to both legs.

In addition, when performing stretching exercises, as shown in FIG. 5, a lock pin 12 is inserted through an arbitrary hole 11 of a plurality of holes 11 formed in a column 10 at the center of the base 1. The treads 3a and 3b are stopped so as not to turn below a predetermined angle, and both heels are attached to the support frame 2 and both hands and feet are stretched and the waist is bent.

As a result, the Achilles tendon can be stretched, and the fatigue of the feet, the pain of the legs and lower back, and the muscle fatigue such as stiff neck and back can be relieved. And, as the insertion position of the lock pin 12 becomes the upper hole 11, the stopping angle of the treads 3a, 3b becomes steeper and the stretch strength increases. Therefore, the support angle of the tread 3 is adjusted according to the flexibility and physical condition of the user's body. The insertion hole 11a below the seesaw rod support shaft 14 of the support post 10 is a storage hole for preventing loss when the lock pin 12 is not used.

[0017]

[Effect of the invention]

 This device is constructed as described above, and when performing a stepping motion to strengthen the leg strength, the compression coil spring and the seesaw rod push up on the opposite tread plate by the compression coil spring and the seesaw rod. A stable and smooth stepping operation can be performed without applying an excessive load, and the spring does not need to have such a strong resilient action.The manufacturing cost is lower than that of the hydraulic cylinder type. By changing the direction of the foot placed on the treadboard by inserting the lock pin into the column, it can be easily changed to a stretching exercise device.
