Description

Technical Field

[0001] This application relates to the technical field of joint protection, and particularly to a joint protection device. Background Art

[0002] The elbow connects the upper arm and the lower arm, skillfully and coordinately integrating arm movements, enabling the arm to perform more perfectly in bending, straightening, and rotating forward and backward. However, tendon fatigue caused by high-repetition labor, excessive exercise, and sudden trauma can lead to conditions such as tennis elbow and golfer's elbow, resulting in limited elbow movement angles and affecting the bending and straightening of the elbow.

[0003] The elbow joint is formed by the articulation of the humerus, radius, and ulna, enabling more perfect performance in directions such as hand bending, straightening, pronation, and supination. Excessive repetitive labor, excessive exercise, and sudden trauma can cause tendon fatigue, inflammation, and abscesses, such as tennis elbow and golfer's elbow. Direct impact on the back of the elbow or long-term compression and friction will cause olecranon bursitis, affecting hand function and causing limited elbow movement angles. In addition, injury to the muscles of the upper arm will affect the bending and straightening of the elbow.

[0004] For the tendons of the elbow that are frequently injured, the joint protection device exerts appropriate pressure on the injured tendons to produce restraint, reducing the degree of injury to the affected part caused by excessive contraction. The design of elbow protectors even has the effect of reducing pain and avoiding fatigue, assisting in more coordinated hand function performance. Elbow protectors can be simply referred to as joint protection devices, and joint protection devices can include sports joint protection devices, simple joint protection devices, and maintenance and rehabilitation joint protection devices.

[0005] In the prior art, the joint protection device includes a protection main body and a binding strap. The protection main body is worn on the elbow, and one end of the binding strap is connected to the protection main body. In actual application, the protection main body is worn on the elbow, and the binding strap is wound around the elbow and bound to the protection main body. In one existing method, the binding strap is bundled by means of end buckles, and the binding strap is passed through the two buckles at least twice, and then tightened to fasten the protection main body to achieve the protection of the elbow.

[0006] However, due to the continuous movement of the elbow, a single binding strap often has insufficient tightening effect on the protection main body. Utility Model Content

[0046] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and in no way limits the present application and its application or use. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative efforts belong to the protection scope of the present application.

[0047] As used herein, the phrase "embodiment" or "embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment or embodiment can be included in at least one embodiment of the present application. The phrase appears in various places in the specification and does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art will explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

[0048] As Figures 1 to 7 shown, an embodiment of the present application provides a joint protection device 10, which can be applied to a joint of a user to protect the joint of the user. In this application, the joint protection device 10 is taken as an example of being applied to a joint of a user with an elbow. It should be understood that the joint protection device 10 can also be applied to other positions, such as the knee.

[0049] The joint protection device 10 includes a protection main body 500, a first protection belt 100, and a second protection belt 200. Both the first protection belt 100 and the second protection belt 200 are connected to the protection main body 500. The first protection belt 100, the second protection belt 200, and the protection main body 500 can surround to form a space 11, and this space 11 can be used to place the joint of the user with an elbow.

[0050] Among them, the protection main body 500 can correspond to the elbow of the user. For example, the inner surface of the protection main body 500 can fit with the elbow of the user. In some cases, the protection main body 500 is made of a flexible material and can play a certain protective role for the elbow of the user. In some cases, a flexible buffer part 600 is provided on the inner surface of the protection main body 500, and the buffer part 600 can play a good role in buffering and shock absorption for the elbow or other joints. Exemplarily, the buffer part 600 is made of SBR diving material. In other embodiments, the buffer part 600 is made of silica gel material.

[0051] Exemplarily, the buffer part 600 is sewn on the inner surface of the protection main body 500 by a sewing method. In other embodiments, the buffer part 600 is arranged on the inner surface of the protection main body 500 by a pasting method.

[0052] One end of the first protective belt 100 is connected to one side of the protective body 500, and one end of the second protective belt 200 is connected to the other side of the protective body 500. That is, the first protective belt 100 and the second protective belt 200 are connected to opposite sides of the protective body 500, and one end of the first protective belt 100 and one end of the second protective belt 200 are located on both sides of the protective body 500. Exemplarily, one end of the first protective belt 100, the protective body 500, and one end of the second protective belt 200 are integrally provided, which can increase the connection stability of the three to a certain extent. In other embodiments, one end of the first protective belt 100 and one end of the second protective belt 200 can both be stitched to the protective body 500.

[0053] The first protective belt 100 and the second protective belt 200 can be connected or separated. For example, the inner surface of the first protective belt 100 can be connected to the outer surface of the second protective belt 200. In other cases, the inner surface of the second protective belt 200 is connected to the inner surface of the first protective belt 100. When the first protective belt 100 and the second protective belt 200 are connected, they can play a role in limiting the protective body 500. Specifically, when the protective body 500 is worn on the user's elbow, the first protective belt 100 and the second protective belt 200 are connected to each other around the arm, and the protective body 500 is fastened to the user's elbow.

[0054] Exemplarily, at least the inner surfaces of the first protective belt 100 and the second protective belt 200 are made of flexible materials, and can also protect the parts of the user that are attached to the first protective belt 100 and the second protective belt 200.

[0055] Wherein, the other end of the first protective belt 100 can be connected to different positions on the outer surface of the second protective belt 200, so that the size of the space 11 formed by the first protective belt 100, the second protective belt 200, and the protective body 500 can be changed.

[0056] Exemplarily, a first connecting component 710 is provided on the inner surface of the first protective belt 100, and a second connecting component 720 is provided on the outer surface of the second protective belt 200. The first connecting component 710 and the second connecting component 720 can be connected or separated from each other, so as to realize the connection or separation of the first protective belt 100 and the second protective belt 200.

[0057] Exemplarily, one of the first connecting member 710 and the second connecting member 720 is provided with a first Velcro layer, and the other is provided with a second Velcro layer. Or, one of the first connecting member 710 and the second connecting member 720 is a male Velcro layer, and the other is a female Velcro layer. It should be noted that the connection or separation method between the first connecting member 710 and the second connecting member 720 is not limited to the two-layer Velcro structure, and other structures can also be adopted. The embodiments of the present application do not limit this.

[0058] In some cases, a part of the second connecting member 720 extends to the outer surface of the protection main body 500. It should be understood that it is also possible that the second connecting member 720 does not extend to the outer surface of the protection main body 500.

[0059] In an optional embodiment of the present application, the joint protection device 10 further includes an elastic band 300. The elastic band 300 is disposed on the inner surface of the first protection band 100, and both ends of the elastic band 300 are disposed on the inner surface of the first protection band 100, while other parts of the elastic band 300 are separated from the inner surface of the first protection band 100. Or, except for the two ends of the elastic band 300, the other parts are not connected to the inner surface of the first protection band 100.

[0060] Exemplarily, one end of the elastic band 300 is disposed on the inner surface of the first protection band 100 near the protection main body 500, and the other end of the elastic band 300 is disposed on the first protection band 100 away from the protection main body 500. The part between the two ends of the elastic band 300 is separated from the inner surface of the first protection band 100. Or, one end of the elastic band 300 is disposed on one end of the first protection band 100, and the other end of the elastic band 300 is disposed on the other end of the first protection band 100.

[0061] Exemplarily, the elastic band 300 can generate elastic deformation, and the length of the elastic band 300 in the unfolded state is greater than its length in the contracted state. Thus, when the user operates the connection process of the first protection band 100 and the second protection band 200, the elastic band 300 can be pulled to generate deformation, so that the elastic band 300 changes from the contracted state to the unfolded state. After the connection of the first protection band 100 and the second protection band 200 is completed, the elastic band 300 remains in the unfolded state, and the elastic band 300 will generate an elastic acting force in the unfolded state, which acts on the first protection band 100, and thus can increase the connection stability between the first protection band 100 and the second protection band 200 to a certain extent, as well as the stability of the limitation on the protection main body 500.

[0062] Exemplarily, the width of the elastic band 300 is smaller than the widths of the first protection band 100 and the second protection band 200.

[0063] Exemplarily, the width of the first protective belt 100 and the width of the second protective belt 200 are substantially equal.

[0064] Exemplarily, the elastic belt 300 is disposed at the middle position of the first protective belt 100, or in other words, both ends of the elastic belt 300 are disposed at the middle positions of the first protective belt 100 in its width direction.

[0065] Exemplarily, the second protective belt 200 is provided with a through hole 202 for the elastic belt 300 to pass through. A part of the elastic belt 300 is disposed in the through hole 202, and the elastic belt 300 can move in the through hole 202. Exemplarily, a limiting portion 201 is disposed on the outer surface of one end of the second protective belt 200 away from the protection main body 500. The limiting portion 201 and the outer surface of the second protective belt 200 jointly define the through hole 202. Exemplarily, the limiting portion 201 and the second protective belt 200 are connected by stitching. It should be noted that the limiting portion 201 and the second protective belt 200 can also be connected by other means. The embodiment of the present application does not limit the connection manner between the limiting portion 201 and the second protective belt 200. In other alternative embodiments, the through hole 202 can also be directly formed in the second protective belt 200.

[0066] In the embodiment of the present application, one end of the second protective belt 200 away from the protection main body 500 maintains a connection relationship with the elastic belt 300, so that one end of the second protective belt 200 away from the protection main body 500 is maintained on the inner surface of the first protective belt 100. The first protective belt 100 and the second protective belt 200 are generally in a preliminary mating connection state with each other, which is beneficial for the user to put the joint protection device 10 on the arm with one hand. Pulling the first protective belt 100 can cause the elastic belt 300 to deform. Then, the first protective belt 100 and the second protective belt 200 can be connected to realize the fastening of the joint protection device 10, so as to protect the user's joints such as the elbows. Compared with the embodiment of the present application that does not include the elastic belt 300 and only adopts the connection manner between the first protective belt 100 and the second protective belt 200, the connection stability between the first protective belt 100 and the second protective belt 200 can be improved, and at the same time, the limiting stability of the protection main body 500 after the connection between the first protective belt 100 and the second protective belt 200 can be increased. In addition, it is also beneficial for the user to operate with one hand.

[0067] Exemplarily, the elastic belt 300 is made of a flexible elastic material.

[0068] In an alternative embodiment of the present application, the joint protection device 10 further includes a fastening belt 400. The fastening belt 400 has a fixed end 410 and a free end 420. The fixed end 410 of the fastening belt 400 is connected to the outer surface of one or more of the first protection belt 100, the second protection belt 200, and the protection body 500. In the embodiment of the present application, the case where the fixed end 410 of the fastening belt 400 is connected to the outer surface of the first protection belt 100 is taken as an example for illustrative purposes. For example, the fixed end 410 of the fastening belt 400 is connected to the outer surface of the first protection belt 100 near the protection body 500. The fastening belt 400 can surround the outer surfaces of the first protection belt 100, the second protection belt 200, and the protection body 500 at least once to be connected or separated, so as to further fasten the first protection belt 100, the second protection belt 200, and the protection body 500.

[0069] Exemplarily, the joint protection device 10 further includes a connecting loop 401. The connecting loop 401 is connected to the fixed end 410 of the fastening belt 400, and the free end 420 of the fastening belt 400 can pass through the connecting loop 401 to be connected or separated. Exemplarily, the fixed end 410 of the fastening belt 400 includes a first part 411 and a second part 412 connected to each other. The first part 411 is connected to the outer surface of the first protection belt 100 near the protection body 500, and the second part 412 defines a mounting hole. The connecting loop 401 is inserted into the mounting hole of the second part 412. In the embodiment of the present application, the second part 412 can be formed by laminating a part of the fastening belt 400 and sewing it on the outer surface of the first protection belt 100. The fastening belt 400 can surround the outer surface of the first protection belt 100, the outer surface of the second protection belt 200, and the outer surface of the protection body 500 such that the free end 420 of the fastening belt 400 passes through the connection hole 403 of the connecting loop 401, and then the free end 420 of the fastening belt 400 is connected to other parts of the fastening belt 400. For example, a third connecting member 730 and a fourth connecting member 740 are provided on the same surface of the fastening belt 400, and the third connecting member 730 and the fourth connecting member 740 can be connected or separated.

[0070] Exemplarily, one of the third connecting member 730 and the fourth connecting member 740 adopts a first magic tape layer, and the other adopts a second magic tape layer. Or, one of the third connecting member 730 and the fourth connecting member 740 is a male magic tape layer, and the other is a female magic tape layer. It should be noted that the connection or separation method between the third connecting member 730 and the fourth connecting member 740 is not limited to the two-layer magic tape structure, and other structures can also be adopted. The embodiment of the present application does not limit this.

[0071] In other optional embodiments, the fastening belt 400 can wrap around the first protective belt 100, the second protective belt 200 and the outer surface of the protective body 500 for at least one circle to connect or separate itself. That is, the fastening belt 400 in the embodiment of the present application can directly wrap around the first protective belt 100, the second protective belt 200 and the outer surface of the protective body 500 for at least one circle to connect or separate itself, without designing the connecting ring 401.

[0072] Exemplarily, the width of the fastening tape 400 is smaller than the widths of the first protective tape 100 and the second protective tape 200 .

[0073] In an optional embodiment, the joint protection device 10 includes not only an elastic band 300, but also a fastening band 400. When the joint protection device 10 is worn on a user's joint such as an elbow, multiple fastening and pressurizing effects can be achieved. For example, in the initial state of the joint protection device 10, the first protection band 100 and the second protection band 200 are not connected, and the fastening band 400 is not connected. First, the user operates the joint protection device 10 with one hand and sets it on the user's joint such as the elbow. Then, the user operates the first protection band 100 with one hand, such as pulling the first protection band 100 to connect to the second protection band 200. During the user's one-hand operation of the first protection band 100, the elastic band 300 can be driven to produce elastic deformation. After the first protection band 100 and the second protection band 200 are connected, the elastic band 300 forms an elastic force due to its elastic deformation, and the elastic force acts on the first protection band 100 and the second protection band 200, thereby increasing the fastening effect of the first protection band 100 and the second protection band 200 on the protection body 500. Finally, the user can operate the fastening belt 400 with one hand to surround the first protective belt 100, the second protective belt 200 and the protective body 500, and then connect the fastening belt 400 itself, so as to achieve secondary fastening of the first protective belt 100 and the second protective belt 200, and the fastening belt 400 can cover the connection position of the first protective belt 100 and the second protective belt 200, so that the fastening belt 400 can further increase the stability of the protective body 500. Therefore, the embodiment of the present application can be effectively worn by one-hand operation, saving time and effort, and the first protective belt 100 and the second protective belt 200 realize the first layer of fastening of the protective body 500, and with the support of the elastic belt 300, the fastening effect of the first protective belt 100 and the second protective belt 200 on the protective body 500 can be greatly improved. In addition, in the process of pulling the fastening belt 400 to tighten, the protective body 500 can be pressurized multiple times. Combined with the elastic belt 300, the first protective belt 100 and the second protective belt 200 are pressurized to increase the fastening effect of the protective body 500. The fastening belt 400 again pressurizes the protective body 500 significantly, and the stability is greatly improved.

[0074] Exemplarily, the width of the elastic band 300 is smaller than the width of the fastening band 400 .

[0075] The above has introduced in detail the joint protection device provided by the embodiments of the present application. Specific examples are used herein to elaborate on the principle and implementation manner of the present utility model. The description of the above embodiments is only used to help understand the method and its core idea of the present utility model; at the same time, for those skilled in the art, according to the idea of the present application, there will be changes in the specific implementation manner and application scope. In summary, the content of this specification should not be construed as a limitation to the present application.
