Description

Technical Field

[0001] This utility model relates to the field of sports assistive tools, and in particular to a patellar band. Background Technology

[0002] The patella is the largest sesamoid bone in the human body, embedded within the quadriceps tendon. It is a flat, triangular bone not connected to other bones, and can displace during strenuous exercise. Therefore, patellar braces are used to protect the knee during activities such as mountain climbing, playing ball games, and running, effectively preventing or reducing knee injuries.

[0003] Currently, patellar straps are strip-shaped structures made of elastic silicone or adjustable-length knitted fabric. When using them, the patellar strap is fixed below the knee, near the popliteal fossa, to protect the patella.

[0004] However, existing patellar bands with a band-like structure apply pressure at the patellar tendon location, with the point of force applied directly to the popliteal fossa. This causes significant pain in the popliteal fossa when users run, jump, or squat. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides a patellar strap with an opening in the pressure-applying body portion, allowing the wearing force to shift downwards and effectively reducing the user's wearing pain.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a patellar band, comprising a band-shaped body of elastic material, the body comprising a first connecting part, a functional part, and a second connecting part connected in sequence.

[0007] The first connecting part and the second connecting part are connected so that the body forms a ring structure that fits below the human knee.

[0008] The active part has an upper band and a lower band;

[0009] When in use, the upper band fits the patellar tendon of the human body, and at least part of the upper band is installed on the human body at a position higher than the installation positions of the first connecting part and the second connecting part.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] The main body of this application is made of an elastic material, such as silicone, TPU, TPE, etc. This material is more suitable for adjusting the size when the main body and the human body are fixed, compared with the knitted material.

[0012] The main body of this application has a strip-like structure. The first connecting part and the second connecting part are equivalent to the two ends of the entire main body. The first connecting part and the second connecting part can be fixedly connected or detachably connected, so that the main body can be easily worn below the knee. Of course, the first connecting part and the second connecting part can be detachably connected, which makes it easier for the main body to fit the knee size of different users, thus broadening its applicability.

[0013] In this application, the functional part is equivalent to the middle position of the main body, which is the position directly below the knee during normal use. This application has an upper strap and a lower strap for the functional part. There are several ways to connect the upper strap and the lower strap, including: First, one end of the upper strap is fixed to the middle of the lower strap, and the other end of the upper strap is fixed to the first connecting part or the second connecting part, and both ends of the lower strap are fixed to the first connecting part and the second connecting part, respectively; Second, based on the first method, the connection positions of the upper strap and the lower strap are interchanged; Third, both ends of the upper strap are connected to both ends of the lower strap, forming a mouth-like structure, and the two connecting ends of the upper strap and the lower strap are then connected to the first connecting part and the second connecting part, respectively.

[0014] Regardless of the connection method used for the upper and lower straps, it is guaranteed that the upper strap and the lower strap are spaced apart, similar to setting an opening in the middle of the main body. When in use, the installation position of the middle part of the upper strap is equivalent to the part of the patellar strap that fits against the patellar tendon in the prior art. The installation positions of the first and second connecting parts that connect to the upper strap are lower than the middle position of the upper end, indicating that the positions of the first and second connecting parts are lower than the popliteal fossa of the human body, thereby reducing the discomfort of wearing the entire patellar strap.

[0015] Meanwhile, based on the presence of the upper strap, without the lower strap, it cannot be guaranteed that the entire body can be fixedly connected to the human knee. At the same time, the lower strap is a pressure transfer strap, which moves the pressure from the first and second connecting parts downward to the area above the calf muscles, completely avoiding the popliteal fossa, further ensuring the comfort of wearing the patellar strap.

[0016] Furthermore, the two ends of the upper belt are set at an angle to the two ends of the lower belt, and the angle between the upper belt and the lower belt is between 50° and 130°.

[0017] Furthermore, the inner side of the upper band is provided with multiple massage protrusions evenly distributed.

[0018] Furthermore, multiple massage protrusions on the upper band are located in the middle of the upper band, and the multiple massage protrusions are distributed in an array.

[0019] Furthermore, raised auxiliary structures are provided on the inner side of the upper band and on both sides of the multiple massage protrusions.

[0020] Furthermore, the inner side of the body is provided with at least a portion of multiple anti-slip protrusions.

[0021] Furthermore, at least one reinforcing structure is provided on the outer side of the body.

[0022] Furthermore, the first connecting part and the second connecting part are detachably connected by a connector;

[0023] The connector includes multiple connection ports and connection protrusions, and the connection protrusions and any connection port can be detachably connected.

[0024] The connecting protrusion and multiple connecting ports are selectively provided on the first connecting part and the second connecting part, and the multiple connecting ports are spaced apart along the length direction of the first connecting part or the second connecting part.

[0025] Furthermore, the length of the first or second connecting part with multiple connection ports can be set to be variable.

[0026] Furthermore, the connection port is opened on the elastic fixing part, the elastic fixing part is fixedly connected to the first connecting part or the second connecting part, and the hardness of the elastic fixing part is greater than the hardness of the first connecting part or the hardness of the second connecting part.

Detailed Implementation

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0034] like Figure 1-5 As shown, a patellar strap includes a strip-shaped body 100 made of elastic material. The body 100 includes a first connecting part 110, an action part 120, and a second connecting part 130 connected in sequence. The first connecting part 110 and the second connecting part 130 are detachably connected by a connector 150 so that the body 100 forms a ring-shaped structure that fits below the human knee. The action part 120 includes an upper band 122 and a lower band 121. Both ends of the upper band 122 and both ends of the lower band 121 are respectively connected to the first connecting part 110 and the second connecting part 130. In use, the middle part of the upper band 122 is installed on the human body at a position higher than the installation positions of the first connecting part 110 and the second connecting part 130.

[0035] Understandably, the body 100 of this application is made entirely of an elastic material, such as silicone, TPU, or TPE. This type of material is more suitable for adjusting the size of the body 100 when it is fixed to the human body compared to a knitted material. In the embodiments of this application, the body 100 is made of silicone.

[0036] The main body 100 of this application has a strip-like structure. The first connecting part 110 and the second connecting part 130 are equivalent to the two ends of the entire main body 100. The two ends are detachably connected, so that the main body 100 can form a ring-like structure that fits below the knee of the human body, enabling the entire main body 100 to achieve the function of being worn. The first connecting part 110 and the second connecting part 130 are detachably connected by a connector 150, which makes it convenient for different users to find the most suitable size to wear. Furthermore, the detachable connection of the first connecting part 110 and the second connecting part 130 also facilitates the wearing and removal of the entire main body 100. The detachable connection method of the first connecting part 110 and the second connecting part 130 can adopt existing magnetic connection, buckle connection, Velcro connection, rope connection, etc., as long as it is ensured that the ring-like structure formed by the entire main body 100 can be used by different users.

[0037] In this application, the functional part 120 is equivalent to the middle position of the main body 100, which is the position directly below the knee during normal use. In this application, the functional part 120 is divided into an upper band 122 and a lower band 121 that are connected to each other, which is equivalent to setting an opening in the middle of the main body 100. When in use, the installation position of the middle part of the upper band 122 is equivalent to the part of the patellar strap that fits against the patellar tendon in the prior art. The installation position of the first connecting part 110 and the second connecting part 130 connected to the upper band 122 is lower than the middle position of the upper end, indicating that the position of the first connecting part 110 and the second connecting part 130 is lower than the popliteal fossa of the human body, thereby reducing the discomfort of wearing the entire patellar strap.

[0038] Meanwhile, based on the presence of the upper strap 122, if the lower strap 121 is not provided, it cannot be guaranteed that the entire body 100 can be fixedly connected to the lower part of the human knee. At the same time, the lower strap 121 is a pressure transfer strap, which transfers the pressure from the first connecting part 110 and the second connecting part 130 to the area above the calf muscle, completely avoiding the popliteal fossa, and further ensuring the wearing comfort of the patellar strap.

[0039] The patellar strap of this application adopts a structure with a partial opening in the main body 100. By using the cooperation of the upper strap 122 and the lower strap 121, it can not only ensure that the entire patellar strap has a good protective effect on the human knee, but also cleverly move the connection point of the main body 100 to the lower part of the popliteal fossa, reduce wearing pain, and effectively alleviate the problem of low wearing comfort of existing patellar straps.

[0040] In some embodiments of this application, the functional part 120 includes an upper band 122 and a lower band 121, which are respectively connected to the first connecting part 110 and the second connecting part 130. Theoretically, the upper band 122 and the lower band 121 can be arranged in parallel, or they can be arranged at an angle. Considering the stability of the overall structure of the body 100, in this application, such as Figure 1 , 2 As shown in Figures 3, 4, and 5, both the upper band 122 and the lower band 121 are similar arc-shaped band structures, and the arc direction of the upper band 122 and the arc direction of the lower band 121 are arranged opposite to each other. At the same time, the function part 120 is symmetrically arranged along the central axis perpendicular to the length direction of the upper band 122, so that the function part 120 is roughly in the shape of an open "mouth". Correspondingly, the two ends of the upper band 122 are respectively set at an angle with the two ends of the lower band 121, and the two included angles between any end of the upper band 122 and the corresponding end of the lower band 121 are the same.

[0041] The upper strap 122 and the lower strap 121 adopt the connection structure shown in the figure. When the first connecting part 110 and the second connecting part 130 are connected to each other, the included angle between them will change depending on the connection tension of the first connecting part 110 and the second connecting part 130. To correspond to this change, this application sets the included angle ∠a between the upper strap 122 and the lower strap 121 between 50-130°. If it is higher than this range, the upper strap 122 and the lower strap 121 will overlap during the pulling process; if it is lower than this range, the intersection of the upper strap 122 and the lower strap 121 will be moved too far back, leaving no room for adjustment.

[0042] At the same time, in order to increase the deformation capability of the upper band 122, such as Figure 1 , 5 As shown, the upper edge and lower edge of the upper band 122 are provided with continuously staggered arc-shaped recesses and arc-shaped protrusions.

[0043] In some embodiments of this application, the inner side of the upper strap 122 is used to conform to the human leg. To enable the upper strap 122 of this application to have a certain massage function, such as... Figure 1 , 2 As shown in Figure 3, this application has multiple massage protrusions 1221 evenly distributed on the inner side. The massage protrusions 1221 are made of the same material as the body 100. The massage protrusions 1221 are small, cone-shaped protrusions, giving them better resilience and allowing them to match the user's movement, continuously massaging and stimulating the patellar tendon, thus providing a good massage effect on the knee. To accommodate the cross-sectional shape of the patellar tendon, each massage protrusion 1221 has a distribution structure that is lower in the middle and higher on both sides, with a height range of 0-5mm and a spacing between 0.2-2mm. It has a frustum-shaped structure with a small surface contact area and a large bottom contact area. The frustum-shaped structure is not limited and can be cylindrical, triangular, or irregular in shape.

[0044] In some embodiments of this application, taking into account the structural characteristics of the lower part of the knee, multiple massage protrusions 1221 of the upper band 122 are disposed in the middle of the upper band 122, and the multiple massage protrusions 1221 are distributed in an array. The multiple massage protrusions 1221 distributed in an array can apply a more balanced force, ensuring a more balanced massage force at the knee position.

[0045] In some embodiments of this application, the upper band 122 is positioned below the knee, on either side of the patellar tendon, in a recessed area. To improve the wearing comfort of the upper band 122 and to provide better pressure to the area below the knee, as follows: Figure 1 , 2 As shown in Figure 3, the inner side of the upper band 122 of this application has raised auxiliary structures 1222 on both sides of the multiple massage protrusions 1221. The raised auxiliary structures 1222 fit perfectly into the depressions on both sides of the patellar tendon, making the patellar band of this application more ergonomic and more comfortable to wear.

[0046] In this application, the array of massage protrusions 1221 on the inner side of the upper band 122 and the protruding auxiliary structures 1222 on both sides focus on applying pressure to the patellar tendon and provide good filling of the depressions on both sides of the patellar tendon, making it more comfortable to wear.

[0047] In some embodiments of this application, the massage protrusions 1221 do have a certain anti-slip effect. However, to further improve the anti-slip effect of the body 100, this application provides at least a plurality of anti-slip protrusions 160 on the inner side of the body 100. The anti-slip protrusions 160 can be distributed in a sheet-like manner on the inner side of the body 100, or they can be distributed in a block-like manner in multiple areas on the inner side of the body 100, depending on the anti-slip force required during use. In this application, as shown... Figure 1 , 2As shown in Figure 3, multiple anti-slip protrusions 160 are evenly distributed on the inner side of the lower band 121. Parts of the anti-slip protrusions 160 extend into the inner sides of the first connecting portion 110 and the second connecting portion 130. On the inner side of the upper band 122, multiple anti-slip protrusions 160 are also provided on both sides of the two protrusion auxiliary structures 1222. These multiple anti-slip protrusions 160 further enhance the anti-slip effect of the body 100, ensuring the long-term and effective use of the entire patellar band.

[0048] In some embodiments of this application, to increase the overall deformation resistance of the body 100, at least one reinforcing structure 140 is provided on the outer side of the body 100. The reinforcing structure 140 can be a reinforcing rib 141 or an annular groove 142. In this application, for example... Figure 1 , 2 As shown in Figure 4, multiple reinforcing ribs 141 are provided on the outer side of the upper band 122. These reinforcing ribs 141 are divided into two groups, with each group extending along the upper band 122 towards the first connecting portion 110 and the second connecting portion 130, respectively. An annular groove 142 is provided on the outer side of the lower band 121, extending to the positions of the first connecting portion 110 and the second connecting portion 130. The various shapes of the reinforcing structures 140 effectively improve the deformation resistance of the body 100 and increase its service life.

[0049] In some embodiments of this application, the connector 150 facilitates multi-point connection between the first connecting portion 110 and the second connecting portion 130, allowing the annular structure formed by the body 100 to fit the legs of different users. Therefore, the connector 150 can be any of the aforementioned magnetic or snap-fit ​​connections. In this application, considering the material of the body 100, the connector 150 includes multiple connection ports 151 and connection protrusions 152. The connection protrusions 152 and any connection port 151 are detachably connected. The connection protrusions 152 and the multiple connection ports 151 are selectively disposed on the first connecting portion 110 and the second connecting portion 130, and the multiple connection ports 151 are spaced apart along the length direction of the first connecting portion 110 or the second connecting portion 130. Figure 1 , 2As shown, in this application, the connecting protrusion 152 is fixed to the outside of the first connecting portion 110 and protrudes outward. The connecting protrusion 152 is similar to a T-shaped block structure, ensuring that after the connecting protrusion 152 and the connecting port 151 are engaged, it has a certain anti-detachment capability. Multiple connecting ports 151 are provided on the second connecting portion 130 and are spaced apart along the length direction of the second connecting portion 130. The connecting port 151 is a through-hole structure adapted to the vertical section size of the connecting protrusion 152. The connecting port 151 has a certain deformation capability to facilitate its detachable connection with the connecting protrusion 152. In use, the connecting protrusion 152 and the connecting ports 151 at different installation positions can be connected to form ring structures of different sizes to fit the size below the knee of different users. Of course, the connecting protrusion 152 can also be set on the second connecting part 130 with the same structure, and the corresponding multiple connecting ports 151 are set on the first connecting part 110. It is only necessary to ensure that the connecting protrusion 152 and the multiple connecting ports 151 are set on the first connecting part 110 and the second connecting part 130 respectively.

[0050] In some embodiments of this application, when the main body 100 is factory-set, the size range below the knee of male and female users can be taken into account, and multiple connection ports 151 are correspondingly provided. However, when a single user uses it, especially for users with smaller sizes below the knee, when the unused length of the second connection part 130 (or the first connection part 110) is large, this part of the structure is located below the user's popliteal fossa, affecting the wearing effect. Therefore, in this application, the length of the first connection part 110 or the second connection part 130 with multiple connection ports 151 is variable. Figure 1 , 2 As shown in Figure 5, the second connecting part 130 of this application is provided with a plurality of connecting ports 151, and a cutting line is provided between each connecting port 151. The user can cut the length of the second connecting part 130 according to the requirements so that the length of the second connecting part 130 is appropriate.

[0051] In some embodiments of this application, the connection port 151 can be directly formed on the second connecting portion 130, or it can be set on the second connecting portion 130 in other ways. In this application, to improve the overall connection stability of the connector 150, the connection port 151 is formed on the elastic fixing portion 153. The elastic fixing portion 153 is fixedly connected to the first connecting portion 110 or the second connecting portion 130, and the hardness of the elastic fixing portion 153 is greater than the hardness of the first connecting portion 110 or the hardness of the second connecting portion 130. For example Figure 1 , 2As shown in this application, the elastic fixing part 153 is located on the second connecting part 130. The elastic fixing part 153 is made of silicone material with a harderness than the second connecting part 130. During production, the two types of silicone are combined into a single piece through secondary solid molding or inserts to complete the assembly of each elastic fixing part 153 and the second connecting part 130. The dual-color solid molding makes the contact position between the connecting protrusion 152 and the connecting port 151 more stable and less prone to deformation and detachment.
