  • the lower body exercise device according to the present embodiment includes a base plate 10 ′ place on a floor; a fixed shaft 20 ′ horizontally supported by the front end of the base plate 10 ′ at a raised position; pivot frames 30 ′ pivotably coupled to the respective left and right ends of the fixed shaft 20 ′; and torsion springs 40 a ′ and 40 b ′ fitted on the fixed shaft 20 ′ and having both ends which are supported by the pivot frames 30 ′ and the base plate 10 ′ such that the pivot frames 30 ′ can be held in a lifted state.
  • Each of left and right pivot frames 30 ′ is composed of a first pivot frame portion 30 a ′ which has a relatively long length and a second pivot frame portion 30 b ′ which has a relatively short length.
  • a rear pedal portion 31 ′ is pivotably coupled to the upper surface of the first pivot frame portion 30 a ′ so that a user's rearfoot portion can be placed on the rear pedal portion 31 ′, and a front pedal portion 32 ′ is pivotably coupled to the rear upper surface of the second pivot frame portion 30 b ′ so that the user's forefoot portion can be placed on the front pedal portion 32 ′.
  • Holes 34 ′ and 35 ′ are defined through the front ends of the first and second pivot frame portions 30 a ′ and 30 b ′ such that a shaft bolt 22 ′ to be detachably coupled to the fixed shaft 20 ′ is inserted through the holes 34 ′ and 35 ′.
  • An external thread 23 ′ is formed on the distal end of the shaft bolt 22 ′, and an internal thread 21 ′ is formed in the fixed shaft 20 ′.
  • finger-pressure protuberances 33 ′ for stimulating the acupoints on the sole of a foot are attached onto the pedal portions 31 ′ and 32 ′.
  • the finger-pressure protuberances 33 ′ can be formed to have the shape of simple protuberances as shown in the drawings, the present invention is not limited to the illustrate shape of the finger-pressure protuberances.
  • the finger-pressure of the finger-pressure protuberances 33 ′ can be adjusted by the elasticity of springs 36 ′ as shown in FIG. 15 .
  • pressing force of the finger-pressure protuberances ( 33 ′) can be adjusted by varying elasticity of springs ( 36 ′). In this variation shown in FIG.
  • the finger-pressure protuberances 33 ′ can be separated from the pedal portion 31 ′, and the springs 36 ′ comprise compression coil springs. In order to increase finger-pressure, the springs 36 ′ can be replaced with those having greater elasticity. Also, the finger-pressure protuberances 33 ′ can be formed to have various sizes so that finger-pressure protuberances 33 ′ having different heights can be installed at proper positions on the sole of the foot.
  • the rear pedal portion 31 ′ is composed of an upper plate 31 a ′, an intermediate plate 31 b ′ and a lower plate 31 c ′.
  • Protuberance installation grooves 31 d ′ are defined in the upper plate 31 a ′ such that the finger-pressure protuberances 33 ′ and the springs 36 ′ are installed in the protuberance installation grooves 31 d ′.
  • the upper plate 31 a ′ and the intermediate plate 31 b ′ are coupled to each other by an engagement shoulder 312 and an elastic projection 311 to be conveniently detached from each other.
  • the upper plate 31 a ′ having the intermediate plate 31 b ′ coupled thereto is fastened to the lower plate 31 c ′ by a bolt 31 e′.
  • the installation structure of the finger-pressure protuberances and the springs is not limited to that illustrated in the drawings and can be modified in a various ways by a person having ordinary knowledge in the art without departing from the technical concept of the present invention.
  • the finger-pressure protuberances 33 ′ can be made of rubber, soft silicon or soft plastic without using the springs 36 ′.
  • the elastic force of the torsion spring 40 a ′ which is installed between first pivot frame portions 30 a ′ and the base plate 10 ′, can be adjusted in a multi-stepwise manner by elastic force adjustment means 50 ′ which is arranged in the base plate 10 ′ so that a load of exercise can be adjusted.
  • the elastic force adjustment means 50 ′ includes a lever 53 ′ which has a handle 51 ′ attached to the upper end thereof and a pinion 52 ′ secured to the lower end thereof, and a slider 56 ′ which has a rack 54 ′ formed on one portion thereof to be meshed with the pinion 52 ′ of the lever 53 ′ and a support part 55 ′ formed in the shape of steps on the other portion thereof to support the middle portion of the torsion spring 40 a′.
  • the elastic force adjustment means 50 ′ is not limited to the lever type illustrated in the drawing and can adopt any other types as long as the elastic force of the torsion spring 40 a ′ can be adjusted.
  • the reference numeral 12 ′ designates a support bar which is detachably coupled to the left and right sides of the base plate 10 ′ and functions to maintain the exercise device in a balanced state.
  • FIG. 16 is a perspective view illustrating a lower body exercise device for use in a sitting position in accordance with still another embodiment of the present invention.
  • a counter ‘s’ for counting the number of pressing the pedals is additionally provided so that a user can check the amount of exercise.
  • the counter ‘s’ is configured such that the number of pressing the pedal is counted by sensing the pedal using a sensor (not shown) so that the amount of exercise can be numerically displayed. Since this configuration of the counter is well known in the art, detailed description thereof will be omitted herein.
