Description

Technical Field

[0001] The invention relates to the technical field of sports protective gear, and in particular to a knee pad with constant pressure. Background Art

[0002] The knee is an extremely important part of the body during exercise, but it is also relatively fragile and easily injured. During exercise, pressure is applied to the knee, which can easily cause the patella to be pulled away from its original position and cause knee joint diseases, such as dislocation, strain, and tearing of the knee tissue.

[0003] Knee pads are widely used to reduce the risk of knee joint injuries because they provide protection for the knee joint. However, existing knee pads are mostly fixed by upper and lower elastic openings, and the tightness cannot be adjusted, which easily causes excessive pressure on local muscles and is inconvenient to wear. Therefore, there is an urgent need for a knee pad that has adjustable tightness, provides constant and adjustable pressure on muscles, and is easy to wear. Summary of the invention

DETAILED DESCRIPTION

[0026] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it. The implementation methods of the present invention are not limited thereto.

[0027] Example 1

[0028] like Figure 1 A constant pressure knee brace, comprising:

[0029] Kneepad body 1, knee protection part 2, upper airbag 3, lower airbag 4, elastic support member 5, controller 6;

[0030] The kneepad body 1 is sleeve-shaped;

[0031] The knee protection part 2 is located on the kneepad body 1 at a position corresponding to the knee;

[0032] The upper airbag 3 and the lower airbag 4 are both located on the kneepad body 1, and are respectively located above and below the knee protection part 2;

[0033] The elastic support member 5 is fixed on the kneepad body 1 and extends from the upper part to the lower part of the kneepad body 1;

[0034] The controller 6 is located above the upper airbag 3 , the controller 6 is communicated with the upper airbag 3 , and the upper airbag 3 is communicated with the lower airbag 4 .

[0035] The knee pad body 1 includes a front end surface 11 and a rear end surface 12, wherein the front end surface 11 is the outer side of the knee pad body 1, with the vertical direction as the center line, close to the patella side when the knee pad body 1 is in normal use; the rear end surface 12 is the outer side of the knee pad body 1, with the vertical direction as the center line, close to the popliteal fossa side when the knee pad body 1 is in normal use.

[0036] The knee protection part 2 , the upper airbag 3 , the lower airbag 4 , and the controller 6 are located on the front end surface 11 , and the elastic support member 5 is located on the rear end surface 12 .

[0037] like Figure 2As shown, the knee protection part 2 includes an annular elastic silicone ring 21 and a highly elastic fabric 22, the annular elastic silicone ring 21 and the highly elastic fabric 22 are connected to form a sleeve ring shape, the center of the sleeve ring shape coincides with the sleeve center of the knee pad body 1, and the annular elastic silicone ring 21 and the highly elastic fabric 22 are fixed in the middle of the knee pad body 1; the annular elastic silicone ring 21 corresponds to the patella position of the knee to limit the displacement of the patella during movement; the highly elastic fabric 22 provides a pre-tightening force, so that the annular elastic silicone ring 21 pressurizes and protects the patella.

[0038] The upper airbag 3 is located on the kneepad body 1 corresponding to the thigh muscle area, and the lower airbag 4 is located on the kneepad body 1 corresponding to the calf area below the patella. The upper airbag 3 and the lower airbag 4 are connected through the trachea 32, and the trachea 32 is located on the upper and lower sides of the front end surface 11 of the kneepad body 1.

[0039] like Figure 2 and Figure 3 As shown,

[0040] The kneepad body 1 includes a top end 13 and a bottom end 14, which are respectively located at the upper and lower ends of the kneepad body 1. The top end 13 and the bottom end 14 are both provided with micro-elastic constrictions, which are respectively used to position the thigh muscles and calf muscles on the upper and lower sides of the knee.

[0041] The controller 6 includes an air outlet 61 , and the upper airbag 3 includes an air inlet 31 . The controller 6 inflates the air inlet 31 of the upper airbag 3 through the air outlet 61 .

[0042] The elastic support member 5 includes an elastic body 51, a loading cloth 1 52, and a loading cloth 2 53. The elastic body 51 is located between the loading cloth 1 52 and the loading cloth 2 53 and is used to fix the elastic body 51. The loading cloth 1 52 and the loading cloth 2 53 are fixed on the upper and lower sides of the rear end surface 12 of the knee pad body 1.

[0043] The loading cloth 1 52 and the loading cloth 2 53 are sewn together around the edges.

[0044] When using a kneepad with constant pressure, the kneepad body 1 is worn on the leg so that the annular elastic silicone ring 21 is aligned with the patella at the protruding position of the knee. The highly elastic fabric 22 exerts a contraction force on the elastic silicone ring 21 through its own elasticity, so that the elastic silicone ring 21 exerts a certain pressure around the patella.

[0045] Before exercising, the controller 6 is turned on, and the controller 6 inflates the air inlet 31 of the upper airbag 3 through the air outlet 61, and the upper airbag 3 inflates the lower airbag 4 through the air tube 32; after the inflation, the upper airbag 3 and the lower airbag 4 respectively apply constant pressure to the thigh muscles and calf muscles, and the pressure makes the wear firm and protects the thigh muscles and the calf muscles below the knees. The pressure of the lower airbag 4 on the muscles below the knees reduces the damage of the meniscus; the controller 6 controls the inflation pressure;

[0046] During exercise, when the knee joint bends, the elastic body 51 stores energy, and when the knee joint is straightened, the elastic body 51 releases energy to provide rebound assistance to the leg muscles.

[0047] After exercise, the air inlet 31 is opened to communicate with the outside world, and the upper air bag 3 is deflated through the air inlet 31, thereby reducing the pressure on the upper and lower leg muscles of the knee; after the upper air bag 3 is deflated, the kneepad body 1 is taken off the leg.

[0048] Although the preferred embodiments of the present application have been described, those skilled in the art may make other changes and modifications to these embodiments once they have learned the basic creative concept. Therefore, the appended claims are intended to be interpreted as including the preferred embodiments and all changes and modifications falling within the scope of the present application.

[0049] Obviously, those skilled in the art can make various changes and modifications to the present application without departing from the spirit and scope of the present application. Thus, if these modifications and variations of the present application fall within the scope of the claims of the present application and their equivalents, the present application is also intended to include these modifications and variations.
