Description

The present invention relates to an exercise apparatus for twisting of the waist and stretching of the thighs, in particular on an exercise machine that assists the user. to work the adductors, abductors and feet to stretch and twist the muscles and tendons of these. Conventional exercise machines are arranged to train muscles in various areas of the body. Leg exercisers include treadmills, thigh compression devices, exercise stairs, muscle stretchers, etc., but few of them are designed to train at the same time adductors and abductors. In addition, conventional exercise equipment arranged to drive both sides of the thighs can be further improved. For example, conventional exercise machines arranged to drive both sides of the thighs have only a simple function and can not lead to other areas of the body. Thus, an innovative arrangement of the thigh exerciser should be well appreciated by the customers and deserves the effort of the manufacturers. Based on several years of experience in the design and manufacture of related products, the Inventor devoted himself to research and development 30 and finally proposes the exercise machine for twists in size and shape. stretching thighs of the present invention.

Considering that few thigh exercise machines (including treadmills, thigh compression devices, exercise stairs, muscle stretchers, leg lifts, etc.) are arranged to drive both adductors and abductors, and thigh exercise machines arranged to drive both sides of the thighs have only a simple function, the present invention provides a multi-function exercise apparatus for torsions waist and stretching of the thighs. The subject of the present invention is therefore an exercise apparatus for twisting of the waist and stretching of the thighs comprising: a base having two handles projecting upwards from the front thereof and two pivoting elements arranged on two sides of it; a first side frame and a second side frame respectively pivotally coupled to both pivoting members; and two sliding devices respectively having pedals and roller devices, said pedals being respectively slidably mounted on the first lateral frame and the second lateral frame by means of the roller devices, the user thus being able to stand standing on the pedals for performing horizontal expansion and contraction exercises, and characterized in that: said roller devices of said sliding devices respectively have pivoting seats, said pedals respectively having pivoting sleeves corresponding to said pivoting seats, and said pivoting sleeves are respectively engaged to said pivoting seats, whereby said pedals can rotate. Before said pivoting sleeves are engaged to the swivel seats, plastic rings may be respectively used to line said swivel seats to increase the rotability of said pedals. The exercise apparatus for waist twisting and stretching of the thighs may further include limiting devices, each of said limiting devices including a stopper rod and a stopper body; said stopper rod being fixedly mounted on a lower portion of said slide device, and said stopper body being fixedly mounted on said first lateral frame or said second lateral frame to limit a position of said stopper rod to avoid said sliding devices slide out of the affected range.

Said resistance elements may be elastic cords. The present invention has the following advantages. 1. Conventional exercise machines include treadmills, thigh compression devices, exercise stairs, muscle stretchers, leg lifts, etc. However, few of them are designed to train both adductors and abductors. For people planning to train their legs, they usually work their legs in a treadmill mode for a longer period of time then stretching the muscles for a shorter period. Nevertheless, such a training mode is a rather irregular exercise of the legs. The exercise apparatus for twisting and stretching thighs of the present invention comprises a base; a first side frame and a second side frame respectively arranged on two sides of the base; and two sliding devices respectively arranged on the two lateral frames and slidable horizontally. The sliding devices have pedals arranged thereon and resistance members arranged therebelow. When the user is standing on the pedals and both feet apply a force on the pedals away from the horizontal direction, the sliding devices slide outward horizontally and the resistance elements generate resilience. vis-à-vis the sliding devices at the same time. Thus, the user can train his adductors and abductors and stretch the muscles and tendons of them to tone his legs. The roller devices of the sliding devices respectively have swivel seats. The pedals respectively have pivoting sleeves on the lower part thereof to engage the swivel seats. In addition, plastic rings respectively strip the swivel seats and interpose between the swivel seats and the pivoting sleeves to increase the rotability. Therefore, the present invention can also allow the exercise of torsion of the foot. 2. The base of the exercise apparatus of the present invention is pivotally coupled to the first side frame and the second side frame through the pivoting members. Thus, the first side frame and the second side frame can be extended horizontally when the exercise machine is to be used, and the first side frame and the second side frame can be folded vertically to reduce the space occupied and facilitate storage. .

Referring to Figures 1-5, it can be seen that the exercise apparatus for twisting and stretching thighs according to the present invention comprises: - a base 10 having two handles 11 projecting towards the top from the front of the latter and two pivoting elements 12 arranged on two sides thereof; a first lateral frame 20 and a second lateral frame 30 respectively pivotally coupled to the two pivoting elements 12; and two sliding devices 40 and 50 respectively having pedals 41 and 51, roller devices 42 and 52, resistance members 43 and 53 and pulley devices 44 and 54, the lower portions of the pedals 41 and 51 being respectively slidably mounted on the first side frame 20 and the second side frame 30 via the roller devices 42 and 52; roll devices 42 and 52 having hooks 421 and 521, respectively; the hooks 421 and 521 respectively clinging to the ends of the resistance members 43 and 53; the other ends of the resistance members 43 and 53 respectively wrapping around the pulley devices 44 and 54 and then hooking onto the hooks 21 and 31 of the fixed ends of the first side frame 20 and the second side frame 30, thereby permitting the user to stand on the pedals 41 and 51 to perform contraction exercises and horizontal extension.

The roller devices 42 and 52 of the sliding devices 40 and 50 respectively have pivoting seats 422 and 522. The pedals 41 and 51 respectively have pivoting sleeves 411 and 511 on the lower part thereof. The swivel seats 422 and 522 are respectively engaged to the pivoting sleeves 411 and 511. A plastic ring 60 lugs the swivel seat 422/522 and interposes between the swivel seat 422/522 and the pivoting sleeve 411/511 to increase sliding ability. Thus, the user can also perform the exercise of the foot twists. Sliding devices 40 and 50 may further have limiting devices 70. Each limiter device 70 includes a stopper rod 71 and a stopper body 72. The stopper rods 71 are respectively fixedly mounted on the lower parts of the devices. sliding members 40 and 50. The stop bodies 72 are respectively fixedly mounted on the inner sides of the first lateral frame 20 and the second lateral frame 30 to block the stop rods 71 to prevent the sliding devices 40 and 50 do not slide out of the affected range. The base 10 is pivotally coupled to the first side frame 20 and the second side frame 30 through the pivoting members 12, whereby the first side frame 20 and the second side frame 30 may be horizontally extended when the apparatus The exercise should be used, and the first side frame 20 and the second side frame 30 can be folded vertically to reduce the volume and save storage space. The resistance members 43 and 53 may be elastic members or elastic ropes.

When the user plans to use the exercise apparatus for waist twists and leg stretches according to the present invention, he stands on the pedals 41 and 51 of the sliding devices 40 and 50. Then, its feet apply a force to the outside to cause the sliding devices 40 and 50 to slide outwardly horizontally. As the sliding devices 40 and 50 slide outwardly, the resistor members 43 and 53 generate resilience to the slide devices 40 and 50. The user must apply a force greater than the resilience to maintain the sliding outwards of the sliding devices 40 and 50. When the feet of the user apply a force lower than the resilience or they apply no force, the sliding devices 40 and 50 are returned to the positions initials. A repetition of the actions mentioned above can make the muscles and tendons of the adductors and abductors work. The pedals 41 and 51 are respectively coupled to the swivel seats 422 and 522 of the roller devices 42 and 52 through the pivoting sleeves 411 and 511, whereby the pedals 41 and 51 can rotate and whereby the user can simultaneously perform the exercise of twisting his body or feet when he is working the muscles and tendons of the adductors and abductors. Therefore, the present invention allows for diversified workouts.
