Description

Energy storage formula knee joint protector

Technical Field

The utility model relates to the field of exercise auxiliary equipment, in particular to an energy storage type knee joint protector.

Background

With the progress of society and the aging of population in China, the number of semi-disabled old people is increasing, and many old people cannot walk even stand for a long time due to the reduced leg strength or have the risk of falling down when kneeling during movement due to insufficient leg strength.

At present, no wearable device with low cost, light weight and effectiveness for assisting the movement of the knee joint has a protective effect when standing and walking, most energy storage mechanical knee joint power assisting devices are laterally mounted, the energy storage devices are arranged on the inner side or the outer side of the knee joint, the force provided by the knee joint is indirect, the torque exists, the position fixed on the leg cannot be stable, and the knee joint cannot be protected when falling down on the kneeling place.

Disclosure of Invention

For solving the above problem, the utility model provides an energy storage formula knee joint protector, it is light wearable, with low costs, can dress the use in the user directly effectively provide the knee joint helping hand, can effectively protect the knee joint when falling down kneeling.

In order to achieve the above purpose, the technical scheme of the utility model is as follows: an energy-storage knee joint protector comprises a leg belt, an upper support arm, a hinge, an energy-storage spring, a pull wire, a pulley, a knee nail, a lower support arm and an ankle belt.

The knee nail is fixed in front of the knee joint of a user, the upper edge of the knee nail is connected with a hinge, the upper support arm is of a hollow structure and is connected with the hinge, and the leg belt is connected with the upper part of the upper support arm; the lower support arm is connected with the lower edge of the knee nail, and the ankle belt is connected with the lower part of the lower support arm; the energy storage spring is arranged in the upper support arm, the upper end of the energy storage spring is connected to the top of the inner cavity of the upper support arm, the pulley is connected to the lower end of the upper support arm, and the upper end of the stay wire is connected to the lower end of the energy storage spring and is connected to the lower support arm after passing through the pulley.

Further, the knee nail is fixed in front of the knee joint of the user to form a pressure contact surface.

Further, the upper support arm can rotate within 180 degrees of freedom around the hinge.

Furthermore, the energy storage spring is used for storing energy by tension, when a user squats or bends the knee, the stay wire is pulled out from the inner part of the upper arm by the lower arm, the upper end of the stay wire pulls the energy storage spring to stretch to form elastic potential energy for storing energy, and when the user needs to do knee extension action, such as changing from a squat posture to a standing posture or changing from bending the knee to straightening the leg, the elastic potential energy is released to provide assistance for the knee joint.

Furthermore, the knee nail is positioned in front of the knee joint of the user, when the user kneels down, the knee part of the user is not directly contacted with the ground, but the energy storage type knee joint protector is contacted with the ground, so that the energy storage type knee joint protector can effectively buffer the ground, and the protection effect is achieved.

The beneficial effects of the utility model reside in that: simple structure is stable, and is lightly ventilative, dresses or takes off at any time according to user's needs, and the direction of force is direct, does not produce the unnecessary moment of torsion when providing the helping hand, and is with low costs, easy to maintain, and it only need to take on and take off the operation to leg area and ankle area can.

Detailed Description

Referring to fig. 1-3, the present invention relates to an energy storage knee joint protector, which comprises a knee nail 5 fixed in front of the knee joint, a hinge 4 connected to the upper edge of the knee nail, an upper arm 3 connected to the hollow structure of the hinge, a leg band 1 connected to the upper end of the upper arm, an energy storage spring 2 connected to the top of the inner cavity of the upper arm, a stay wire 8 connected to the lower end of the energy storage spring at the upper end and a lower arm 6 connected to the lower end of the stay wire 8, a pulley 9 connected to the lower end of the upper arm, a lower arm 6 connected to the lower edge of the knee nail, and an ankle band 7 connected to the lower end of the lower arm.

Wherein the leg strap 1 is fixed on the thigh of the user, the ankle strap 7 is fixed on the lower leg of the user, and the knee nail 5 clings to the front side of the knee of the user to form a pressure contact surface.

The hinge 4 provides a fulcrum function for a lever structure formed by the upper supporting arm 3, and the energy storage spring 2 is stretched by a stay wire 8 to store energy by winding a pulley 9 when a user squats or bends the knee.

Further, referring to fig. 1, when the user stands up from the squatting position, the energy storage spring 2 pulls back the pull wire 8, and because the lower end of the pull wire 8 is connected and fixed to the lower support arm 8 and passes around the pulley 9, the pull wire 8 generates a moment of counterclockwise rotation along the hinge 4 to the pulley 9, thereby driving the upper support arm 3 and the leg belt 1 connected to the upper end of the upper support arm to generate upward and forward assistance to the thigh of the user.

Further, as shown in fig. 1, when the power assisting operation is performed, the upper arm 3 applies a component force to the hinge 4 in the right direction, presses the knee nail 5, generates a thrust force to the knee in the right direction, and also plays a role in assisting the standing.

Further, please refer to fig. 1-3, the wearing manner of the present invention is simple: only two fixing belts of the leg belt 1 and the ankle belt 7 are provided, the knee nail is directly attached to the front part of the knee when the ankle band is worn, and the two fixing belts are fixed after the leg is straightened, so that the ankle band can be worn; the contact with the body is surface contact, and the pressure on the body is effectively reduced while the force is applied.

The above embodiments are only intended to describe the preferred embodiments of the present invention, but not to limit the scope of the present invention, and various modifications and improvements made by the technical solutions of the present invention by the engineers in the art should fall within the protection scope determined by the claims of the present invention without departing from the design spirit of the present invention.
