[0001] EXCISE APPARATUS FOR SQUAT [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a squat exercising apparatus, and more particularly, to a squat exercising apparatus capable of guiding a squat posture and an operation by supporting a front part of a user including a thorax and a knee position, ≪ / RTI >

In general, the squat position is achieved through the necessary movements in human life. For example, a modified behavior of the squat is being performed every day, from a human being in a usual position of squatting, to picking up a box in daily life, or to sit on a chair.

In this human movement, we can see that the squat posture is very deeply related to weight training as well as daily life and specific sports activities. The ability to perform a squat posture or movement in a safe and correct manner can prevent injuries and enable healthy, pain-free lives, so a squat movement with correct motion is required to respond to the correct squat posture.

For example, according to the squat movement, breathing stood up while sitting and breathing while taking up, breathing out again. The chin is lightly blocked and prevents the back from burning. At this time, the forward head posture is associated with neck pain, shoulder pain, and jaw joint dysfunction, so it may be important that the head posture and the posture and angle of the chest supporting the head are also accurate. In particular, observers of excessive neck or neck extensions may be made on a side-by-side basis, with the head in the front and rear views being at the centerline of the body and not moving left or right.

Also, the waist should always be straight and the abdomen should be stretched to create tension. The hips need to be lowered slowly as they sit back on the chair. Keep your knees forward from your toes, and spread your legs around your pelvis or shoulder width.

However, the exercise assist device for squat movement according to the prior art does not have a means for precisely performing a sitting up operation while supporting the chest with the waist in a straight state.

In addition, it is difficult to adjust the height of the knee front support required for the squat position, and it is very difficult to adjust the knee so that the knee does not go beyond the toes while preventing the hips from falling down excessively.

In addition, the prior art does not have a means for securely holding and supporting the apparatus or the apparatus itself between the ground and the ceiling so that the exerciser can take a stable posture. In particular, it is difficult for a beginner, the elderly person, a child, or a patient having a physical disability to start a squat movement to perform a correct squat movement. As a result, the exercising effect may not be obtained due to repeated posture and operation erroneously, and safety accidents such as muscle, joint and ligament injuries may occur.

As such, the squat posture exercise itself can strengthen the whole body as a whole body exercise, but importantly, the squat operation must be performed safely, effectively and accurately, so that the knee and ankle joints are prevented from being excessively bent while performing a correct squat posture, Upper and Lower Muscles There is a urgent need for a means to enable more than 200 muscle groups to exert synergy.

1 is a perspective view of a squat exercising apparatus according to an embodiment of the present invention, and FIG. 2 is a sectional view taken along line A-A shown in FIG. 1. Referring to FIG.

Referring to FIGS. 1 and 2, the squat exercising apparatus 10 according to the present invention may include a chest support 100, a frame 200, a leg support 300, and a waist support 400.

The chest support 100 may play a role of supporting the chest of the user corresponding to the squat movement posture by the detailed configuration and shape to be described in detail below.

The squat movement posture needs to be based on the observation direction corresponding to the front and side surfaces of the user or the exerciser, or the rotation operation based on the user's cross section or the longitudinal section needs to be accurately performed. At this time, the user spreads the position of his or her foot to the shoulder width of the base plate 230, and the inside of the foot can stand side by side with the outside of the shoulder.

You can also place your hands behind your ears by pointing your feet straight up and straight up over your head. This position or posture may activate the back muscles of the upper trunk, which provide stability and provide posture of the scapula. Also, the user's head is aligned with the shoulder, and the gaze needs to look straight ahead.

In particular, it is necessary to keep the heel of the user away from the upper surface of the base plate 230. During the squat exercise, the user should be able to comfortably lower the pelvis by pushing it back as if sitting on a virtual chair, and the tempo should be 2 to 3 seconds. Such an attitude motion of the squat movement can be repeated three to five times.

The chest support 100 can support the trunk upright position while being supported by the forward part of the trunk including the chest, for example, the chest or the body part during the squat movement, that is, the squat movement . In addition, by providing a base of support to the chest, a function of reducing the burden of the trunk extensor can be achieved. In addition, the chest support 100 may be height-adjustable up and down on the sliding rail 210 to conform to the body shape through a mechanical design modification (e.g., further comprising a braking device not shown in the sliding rail 210) It may be fixed when held. That is, the strap 150 is detachably attachable with a velcro fastener or the like, so that the entire body of the user can be covered, so that a structure that can be performed safely and securely during exercise can be achieved. That is, since the body is wrapped around the body, when the braking device is interlocked by the movement of the body backward at the appropriate squat position, the posture may be maintained.

The frame part 200 allows vertical movement along the Z-axis direction of the chest support part 100 and prevents horizontal movement of the X-Y plane. For example, the frame part 200 may be provided with a sliding rail 210 to guide the movement of the chest support 100 in the vertical direction. Here, the extending direction of the sliding rail 210 may be the same as or similar to the Z-axis direction or the vertical direction of the frame portion 200. In addition, the movement in the Z-axis direction or the vertical direction may mean a direction for the user to sit and stand in a state in which the user's chest is restrained by the chest support unit 100.

The leg support portion 300 is coupled to the height control rail 220 formed on the frame portion with respect to the lower position of the sliding rail 210. The guide piece 310 of the leg support portion 300 is inserted between the legs of the user So that it can play a role of supporting the shin part or the thigh part of the user's shin. Here, the thigh portion may include the back portion of the thigh.

The leg support 300 may be a kind of adjustable knee joint support. The leg support 300 has a structure that supports the knee of the user in a squat posture so that the knee of the user is gathered inward to prevent a body misalignment from occurring while allowing a correct posture motion. The height adjustment pin 340 may be replaced with a height adjusting pin 340 after the structural design is changed to adjust the distance between the guide pieces 310 according to the body shape of the user, May be made to be fixed at an appropriate position when the knee is released.

A damper 211 may be attached to the bottom of the sliding rail 210 or the height adjusting rail 220 to damp the impact of the sliding block 110 or the moving block 320. Here, the damper 211 can reduce the impact and noise, thereby achieving the effect of preventing the structural damage caused by the operation of the chest support 100 and the leg support 300 in advance.

Particularly, the leg supporting portion 300 can play a role of restraining the user's knee from going forward beyond the user's toes during the squatting exercise and supporting the portion below the thighs in order not to excessively bend the knees corresponding to the squat posture Shape. The leg support part 300 is provided with a height adjusting function so that the height or height of the guide piece 310 can be adjusted according to the user's body shape.

The waist support part 400 is disposed with reference to a position between the sliding rail 210 and the height adjustment rail 220, and can play a role of supporting the waist of the user while elastically supporting it.
