Description

Technical Field

[0001] The utility model relates to the technical field of protective equipment, and particularly relates to an ankle rigid protection structure. Background Art

[0002] The ankle joint, formed by the articular surfaces at the lower ends of the tibia and fibula and the trochlea of the talus, is also known as the talocrural joint. The "冂"-shaped joint fossa formed by the lower articular surface of the tibia and the medial and lateral ankle articular surfaces accommodates the trochlea of the talus (articular head). Since the trochlear joint surface is wider in the front and narrower in the back, when the foot is dorsiflexed, the wider front part enters the fossa and the joint is stable; but when the foot is plantarflexed, such as when going downhill, the narrower rear part of the trochlea enters the fossa, the ankle joint is loose and can make lateral movements, and at this time the ankle joint is prone to sprain, among which adduction injury is the most common, because the lateral malleolus is longer and lower than the medial malleolus, which can prevent excessive eversion of the talus.

[0003] Ankle joint injuries often occur in some sports. For example, in extreme sports such as skydiving, adduction and eversion injuries are more likely to occur, and even fracture and dislocation may occur. Therefore, ankle protection devices are often worn for protection.

[0004] However, currently, ankle protection devices usually use flexible fabrics to wrap the ankle joint, and then sew plates with relatively high elasticity into the flexible fabrics. The protection effect of this protection structure is poor. The fabric cannot provide sufficient restraint force for the ankle joint, and the plate cannot be designed to be large in order to adapt to the shape of the foot, and the support strength is insufficient due to elasticity, and it cannot provide effective support when the foot rotates relative to the leg and causes adduction and eversion of the ankle joint.

[0044] In the description of the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", and "fixed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0045] In the description of the present invention, the description with reference to the terms "one embodiment", "some optional implementations" or "some optional embodiments" etc. means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present invention. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in any one or more embodiments or examples in a suitable manner.

[0046] At present, ankle injuries often occur in some sports. For example, in extreme sports such as skydiving, adduction and eversion injuries are more likely to occur, and even fractures and dislocations may occur. Therefore, ankle protection devices are often worn for protection. However, current ankle protection devices usually only have flexible cloth wearing structures. Due to the poor restriction effect and insufficient support force of the cloth wearing structure, the protective effect is poor. The utility model provides strong support for the ankle joint through a rigid wearing piece, which can provide excellent protection for the ankle joint of the human body.

[0047] See also Figure 1 An embodiment of the utility model provides a rigid ankle protection structure, including: a rigid wearable piece 10.

[0048] Please also read Figures 2 to 6 The rigid wearable article 10 has a first binding structure 11 and a second binding structure 12, the first binding structure 11 and the second binding structure 12 are movably connected, and a first limiting structure 20 is arranged between the first binding structure 11 and the second binding structure 12. When the rigid ankle protection structure is worn on a human body, the first binding structure 11 is bound to the human body's leg, and the second binding structure 12 is bound to the human body's foot. The first limiting structure 20 can limit the inward turning angle and / or outward turning angle of the second binding structure 12 compared to the first binding structure 11, so as to limit the adduction angle and / or eversion angle of the ankle joint of the human foot. When the user's foot lands, the ankle joint may have a tendency to adduct or evert, and the rigid wearable article 10 can provide strong support for the ankle joint, and the protection effect is better.

[0049] Since the rigid wearable article 10 is relatively large in size and highly rigid, the second binding structure 12 of the rigid wearable article 10 can be worn on the outside of the user's boots, making it easier to wear. There is at least one boot layer between the second binding structure 12 and the human foot, which is beneficial for improving the comfort of the foot. Of course, depending on the actual structure and usage scenario of the rigid wearable article 10, the rigid wearable article 10 can also be worn in other suitable ways.

[0050] The first limiting structure 20 It should be noted that the rigid wearable component 10 is partially or entirely made of rigid material, and the rigid material has a higher hardness and high compressive and flexural strength. Therefore, when the second binding structure 12 is flipped relative to the first binding structure 11 and until it is restricted by the first limiting structure 20, the first binding structure 11 and the second binding structure 12 are not easily deformed due to their high hardness, and can provide stable support for the legs and feet, thereby better limiting the position of the feet relative to the legs, and then limiting the ankle joint without prone to adduction and eversion.

[0051] Please also read Figures 3 to 6 The specific structure of the first limiting structure 20 can be designed according to actual needs. In some optional embodiments, the first limiting structure 20 includes an inward limiting portion 21 and an outward limiting portion 22; the inward limiting portion 21 and the outward limiting portion 22 are arranged on the first binding structure 11 or the second binding structure 12, and the inward limiting portion 21 and the outward limiting portion 22 are used to limit the inward turning angle and the outward turning angle of the second binding structure 12 compared with the first binding structure 11. In this embodiment, the inward limiting portion 21 and the outward limiting portion 22 are arranged on the second binding structure 12 as an example for description. When the ankle joint of the human body shows a tendency to adduct, the foot of the human body will turn inside the legs relative to the legs, and the foot will drive the second binding structure 12 to turn inward relative to the first binding structure 11. When the adduction limiting portion 21 abuts against the first binding structure 11, the second binding structure 12 cannot continue to turn inward, and the adduction limiting portion 21 limits the inward turning angle of the second binding structure 12, thereby limiting the inward turning of the foot relative to the leg, thereby avoiding adduction of the ankle joint to protect the ankle joint. Similarly, when the ankle joint of the human body shows a tendency to evert, the foot of the human body will turn outside the legs relative to the legs, and the foot will drive the second binding structure 12 to turn outward relative to the first binding structure 11. When the evert limiting portion 22 abuts against the first binding structure 11, the second binding structure 12 cannot continue to turn outward, and the evert limiting portion 22 limits the outward turning angle of the second binding structure 12, thereby limiting the outward turning of the foot relative to the leg, thereby avoiding evert of the ankle joint to protect the ankle joint.

[0052] In some embodiments, the inward limiting portion 21 and the outward limiting portion 22 are arranged on the first binding structure 12. Taking the human body in a normal standing posture as a reference state, the inward limiting portion 21 and the second binding structure 12 have a first angle (not shown in the figure), and the first angle provides a limiting stroke for the second binding structure 12 to flip inward compared to the first binding structure 11. The outward limiting portion 22 and the second binding structure 12 have a second angle (not shown in the figure), and the second angle provides a limiting stroke for the second binding structure 12 to flip outward compared to the first binding structure 11. The angle of the first angle is set to be smaller than the angle of the second angle.

[0053] At the same time, the inward limiting portion 21 and the outward limiting portion 22 can also be arranged on the second binding structure 12. Similarly, taking the human body in a normal standing posture as a reference state, the inward limiting portion 21 has a first angle with the first binding structure 11, and the first angle provides a limiting stroke for the second binding structure 12 to flip inward compared to the first binding structure 11. The outward limiting portion 22 has a second angle with the first binding structure 11, and the second angle provides a limiting stroke for the second binding structure 12 to flip outward compared to the first binding structure 11. The angle of the first angle is set to be smaller than the angle of the second angle.

[0054] In this embodiment, the adduction limiting portion 21 and the eversion limiting portion 22 are set on the second binding structure 12 as an example for explanation. Since ankle adduction is more common and easy to occur, taking the human body in a normal standing posture as a reference state, the angle of the first angle is set to be smaller than the angle of the second angle. This design is more inclined to quickly prevent the human foot from transitioning inversion. When the human foot is inverted, the first binding structure 11 can be against the adduction limiting portion 21 more quickly, thereby limiting the inversion angle of the second binding structure 12 relative to the first binding structure 11 as soon as possible, which is conducive to limiting the possibility of ankle adduction as much as possible and improving the protection effect.

[0055] Please refer to Figure 3 , which shows that the adduction limiting portion 21 and the eversion limiting portion 22 are arranged on the second binding structure 12, and the human body is in a normal standing posture at this time. At this time, the angle of the first angle is 0° (the adduction limiting portion 21 is completely in contact with the first binding structure 11, so the first angle is 0°), and the angle of the second angle is greater than the angle of the first angle (there is a gap between the eversion limiting portion 22 and the first binding structure 11, and the second angle is not 0°). Of course, in other embodiments, the angle of the first angle can also be designed to be greater than 0°.

[0056] When the human body is in a normal standing posture, the first angle between the inward limiting portion 21 and the first binding structure 11 is set to 0°, that is, in this state, the first binding structure 11 is in contact with the inward limiting portion 21. In this way, the inward turning angle of the second binding structure 12 compared to the first binding structure 11 is basically 0°. When the human body's foot is impacted by external force, the human body's foot basically cannot turn inward, thereby effectively preventing the human body's foot from turning inward and improving the protection effect on the ankle joint.

[0057] See also Figure 7 and Figure 8When the first limiting structure 20 is arranged on the first binding structure 11, the first binding structure 11 forms a limiting end surface along the sagittal plane direction of the human body, and the limiting end surface has a connecting transition area 23 and a first limiting surface 211 and a second limiting surface 221 respectively extending to both sides from the connecting transition area 23. The first limiting surface 211 constitutes an adduction limiting portion 21, and the second limiting surface 221 constitutes an eversion limiting portion 22. The second binding structure 12 can be respectively abutted against the first limiting surface 211 and the second limiting surface 221 for limiting. When the second binding structure 12 is abutted against the first limiting surface 211 for limiting, the rigid ankle protection structure is in an adduction limiting state, thereby limiting the adduction of the ankle joint. When the second binding structure 12 is abutted against the second limiting surface 221 for limiting, the rigid ankle protection structure is in an eversion limiting state, thereby limiting the eversion of the ankle joint. When the first limiting structure 20 is arranged on the second binding structure 12, the second binding structure 12 forms a limiting end face along the sagittal plane of the human body, and the limiting end face has a connecting transition area 23 and a first limiting surface 211 and a second limiting surface 221 respectively extending to both sides from the connecting transition area 23. The first limiting surface 211 constitutes an adduction limiting portion 21, and the second limiting surface 221 constitutes an eversion limiting portion 22. The first binding structure 11 can be abutted against the first limiting surface 211 and the second limiting surface 221 for limiting. When the first binding structure 11 is abutted against the first limiting surface 211 for limiting, the rigid ankle protection structure is in an adduction limiting state, thereby limiting the adduction of the ankle joint. When the first binding structure 11 is abutted against the second limiting surface 221 for limiting, the rigid ankle protection structure is in an eversion limiting state, thereby limiting the eversion of the ankle joint.

[0058] In this embodiment, the adduction limiting portion 21 and the eversion limiting portion 22 are provided on the second binding structure 12 as an example for explanation. The design of the limiting end surface allows the first binding structure 11 to achieve surface contact with the first limiting surface 211 or the second limiting surface 221 when the ankle rigid protection structure is in the adduction limiting state or the eversion limiting state, thereby improving the stability and strength of the first binding structure 11 when it abuts against the adduction limiting portion 21 and the stability and strength of the first binding structure 11 when it abuts against the eversion limiting portion 22. Of course, when the second binding structure 12 and the first binding structure 11 have other active angles, the first binding structure 11 can also achieve point or surface contact with the adduction limiting portion 21 or the eversion limiting portion 22, thereby achieving limiting.

[0059] See also Fig. 9When the ankle rigid protection structure is worn on a human foot, the first limiting surface 211 is arranged farther away from the sole of the human foot than the second limiting surface 221, and the first limiting surface 211 and the second limiting surface 221 are arranged at an angle. The angle between the first limiting surface 211 and the second limiting surface 221 constitutes a preset angle a for providing the human foot with the freedom to turn outward and inward. The preset angle a provides a range in which the second binding structure 12 can freely flip relative to the first binding structure 11. The determination of the size of the preset angle a needs to meet the following requirements: it is necessary to provide an activity space or activity angle between the first binding structure 11 and the second binding structure 12, so that when the human body moves, the second binding structure 12 can freely flip relative to the first binding structure 11 within a certain range to adapt to the movement posture of the human body, and avoid the first binding structure 11 and the second binding structure 12 interfering with and hindering the movement of the human body due to the inability to move with each other; it is also necessary to avoid setting the preset angle a too large. Once the preset angle a is set too large, the activity space or angle between the first binding structure 11 and the second binding structure 12 is too large, and it is difficult to prevent the human ankle joint from transitioning outward or inward. Among them, the preset angle a is designed according to the actual restriction requirements, such as 180°, 185°, 190°, 195°, 200°, 205°, 210°, 225°, 240°, etc.

[0060] The inward limiting portion 21 and the outward limiting portion 22 are connected by a connecting transition area 23 and are formed on the same limiting end surface, which is beneficial to improving the integration of the first limiting structure 20 and making the structure more compact. Of course, the formation of the inward limiting portion 21 and the outward limiting portion 22 is not limited to this. Those skilled in the art can also choose other suitable structures according to the teachings of the present utility model. The purpose of the inward limiting portion 21 and the outward limiting portion 22 is to limit the flipping angle of the first binding structure 11 or the second binding structure 12. Therefore, the inward limiting portion 21 and the outward limiting portion 22 can also be arranged on the flipping path of the first binding structure 11 or the second binding structure 12. Therefore, the inward limiting portion 21 and the outward limiting portion 22 can also be arranged at a longer distance to adapt to actual needs.

[0061] Please also read Fig.10 and Fig.11When the user walks, the ankle joint will plantar flex and / or dorsiflex, and the second binding structure 12 will flip forward or backward relative to the first binding structure 11, so as to adapt to the human body's movement posture, thereby avoiding affecting the user's normal walking. However, when the ankle joint is excessively plantar flexed and / or dorsiflexed, it will also cause damage to the ankle joint. For this reason, in some optional embodiments, a second limiting structure 30 is further provided between the first binding structure 11 and the second binding structure 12. When the ankle rigid protection structure is worn on the human foot, the second limiting structure 30 can limit the forward flipping angle and / or backward flipping angle of the second binding structure 12 compared to the first binding structure 11, so as to limit the plantar flexion angle and / or dorsiflexion angle of the ankle joint of the human foot, thereby protecting the ankle joint.

[0062] Please also read Fig.10 and Fig.11 The specific structure of the second limiting structure 30 can be designed according to actual needs. In some optional embodiments, the second limiting structure 30 includes a plantar flexion limiting portion 31 and a dorsiflexion limiting portion 32; the plantar flexion limiting portion 31 and the dorsiflexion limiting portion 32 are arranged on the first binding structure 11 or the second binding structure 12, and the plantar flexion limiting portion 31 and the dorsiflexion limiting portion 32 are respectively used to limit the forward flipping angle and the backward flipping angle of the second binding structure 12 compared with the first binding structure 11. In this embodiment, the plantar flexion limiting portion 31 and the dorsiflexion limiting portion 32 are provided on the second binding structure 12 as an example for explanation. During the walking process of the human body, the foot will flip forward relative to the leg so that when the ankle joint plantar flexion activity is realized, the foot will drive the second binding structure 12 to flip backward relative to the first binding structure 11, until the plantar flexion limiting portion 31 abuts against the first binding structure 11, the second binding structure 12 cannot continue to flip backward, and the plantar flexion limiting portion 31 limits the backward flipping angle of the second binding structure 12, thereby avoiding excessive plantar flexion of the ankle joint. Similarly, during the walking process of the human body, the foot will flip forward relative to the leg so that when the ankle joint dorsiflexion activity is realized, the foot will drive the second binding structure 12 to flip forward relative to the first binding structure 11, until the dorsiflexion limiting portion 32 abuts against the first binding structure 11, the second binding structure 12 cannot continue to flip forward, and the dorsiflexion limiting portion 32 limits the forward flipping angle of the second binding structure 12, thereby avoiding excessive dorsiflexion of the ankle joint.

[0063] See also Figure 7In some optional embodiments, the plantar flexion limiting portion 31 and the dorsiflexion limiting portion 32 are arranged to protrude from the limiting end surface along the cross-sectional direction of the human body, so as to facilitate the reasonable design of the position arrangement of the first limiting structure 20 and the second limiting structure 30, improve the integration between the first limiting structure 20 and the second limiting structure 30, and make the overall structure more compact. Of course, in other embodiments, the plantar flexion limiting portion 31 and the dorsiflexion limiting portion 32 can also be arranged at other suitable positions. The plantar flexion limiting portion 31 and the dorsiflexion limiting portion 32 are intended to limit the flipping angle of the first binding structure 11 or the second binding structure 12, so they can also be arranged at other positions on the flipping path of the first binding structure 11 or the second binding structure 12, so that the plantar flexion limiting portion 31 and the dorsiflexion limiting portion 32 are spaced far enough apart to adapt to actual needs.

[0064] Continue reading Figure 7 In some optional embodiments, the plantar flexion limiting portion 31 and the dorsiflexion limiting portion 32 are respectively protruded from the two ends of the connection transition area 23 provided on the limiting end surface, so as to facilitate the formation of the plantar flexion limiting portion 31 and the dorsiflexion limiting portion 32 at appropriate positions on the first binding structure 11 and the second binding structure 12, so that the design of the first limiting structure 20 and the second limiting structure 30 is more compact. Among them, the connection transition area 23 can be a smooth transition plane or a transition curved surface. Of course, the connection transition area 23 can also be a folded angle portion. In this embodiment, the connection transition area 23 is a folded angle portion formed between the first limiting surface 211 and the second limiting surface 221. When the second binding structure 12 is flipped relative to the first binding structure 11 until the first binding structure 11 abuts against the plantar flexion limiting portion 31 or the dorsiflexion limiting portion 32, the folded angle portion can prevent the second binding structure 12 and the first binding structure 11 from shaking against each other and improve the position stability between the second binding structure 12 and the first binding structure 11.

[0065] The specific connection method of the first binding structure 11 and the second binding structure 12 can be designed according to actual needs, for example, see Figure 7 In some optional embodiments, the first binding structure 11 and the second binding structure 12 are rotatably connected via a pivot portion 40, and at least a portion of the pivot portion 40 passes through the limiting end surface.

[0066] Among them, in some optional embodiments, the pivoting part 40 is a ball head structure. The ball head structure can improve the flexibility of the first binding structure 11 and the second binding structure 12 in rotating relative to each other, so that the range of the second binding structure 12 flipping relative to the first binding structure 11 can better adapt to the movement posture of the human body. Of course, the pivoting part 40 can also adopt a rotating shaft structure. For example, the pivoting part 40 includes a first rotating shaft, a connecting piece, and a second rotating shaft. The first binding structure 11 rotates with the connecting piece through the first rotating shaft, and the second binding structure 12 rotates with the connecting piece through the second rotating shaft. The second binding structure 12 can flip inward or outward relative to the first binding structure 11 through the first rotating shaft, and can flip forward or backward relative to the second binding structure 12 through the second rotating shaft.

[0067] See also Figure 7 In some optional embodiments, the pivot portion 40 at least partially penetrates the transition area 23 of the limiting end surface, and the first limiting surface 211, the second limiting surface 221, the plantar flexion limiting portion 31 and the dorsiflexion limiting portion 32 are all distributed around the outer peripheral side of the pivot portion 40. The plantar flexion limiting portion 31 and the dorsiflexion limiting portion 32 are respectively protruded from the two end portions of the transition area 23 of the limiting end surface, thereby improving the structural integration of the first limiting structure 20 and the second limiting structure 30 and making the structure more streamlined.

[0068] See also Figure 7 In some optional embodiments, when the first limiting surface 211, the second limiting surface 221, the plantar flexion limiting portion 31 and the dorsiflexion limiting portion 32 are all arranged on the first binding structure 11, a groove 13 is provided on the first binding structure 11, and the bottom wall of the groove 13 is arranged along the sagittal plane of the human body, the groove 13 has an opening facing downwardly of the human body and a side wall of the groove 13 protruding from the bottom of the groove 13 along the cross-sectional direction of the human body, and the two ends of the side wall of the groove 13 respectively constitute the plantar flexion limiting portion 31 and the dorsiflexion limiting portion 32, the bottom wall of the groove 13 constitutes a limiting end face, the pivot portion 40 passes through the bottom wall of the groove 13, and at least part of the pivot portion 40 is located at the bottom of the groove 13. In the groove 13; when the first limiting surface 211, the second limiting surface 221, the plantar flexion limiting portion 31 and the dorsiflexion limiting portion 32 are all arranged on the second binding structure 12, a groove 13 is provided on the second binding structure 12, the groove bottom wall of the groove 13 is arranged along the sagittal plane of the human body, the groove 13 has an opening facing upwards of the human body and a side wall of the groove 13 protruding from the groove bottom of the groove 13 along the cross-sectional direction of the human body, the two ends of the side wall of the groove 13 respectively constitute the plantar flexion limiting portion 31 and the dorsiflexion limiting portion 32, the groove bottom wall of the groove 13 constitutes a limiting end face, the pivoting portion 40 passes through the groove bottom wall of the groove 13, and at least part of the pivoting portion 40 is located in the groove 13. In this embodiment, the first limiting surface 211, the second limiting surface 221, the plantar flexion limiting portion 31 and the dorsiflexion limiting portion 32 are all arranged on the second binding structure 12 as an example for description.

[0069] In the present embodiment, the specific structures of the first limiting structure 20 and the second limiting structure 30 are respectively constituted by the bottom wall of the groove 13 and the side wall of the groove 13. Since the first limiting structure 20 and the second limiting structure 30 are both formed on the groove 13, the first limiting structure 20 and the second limiting structure 30 are highly integrated to form a whole, and the structure is more compact. At the same time, the groove 13 structure also has a high structural strength, which improves the service life. In addition, the pivot part 40 is configured to partially penetrate the bottom wall of the groove 13. Through the structure of the groove 13, the first limiting structure 20, the second limiting structure 30 and the pivot connection structure are cleverly integrated into one, and the first limiting surface 211, the second limiting surface 221, the plantar flexion limiting portion 31 and the dorsiflexion limiting portion 32 are creatively distributed around the outer peripheral side of the pivot part 40. When it is necessary to switch from a single limiting state to a state in which the first limiting structure 20 and the second limiting structure 30 are simultaneously limited, since the pivot part 40 is located at the center of all the limiting structures, the switching is fast and continuous.

[0070] Of course, according to actual needs, the first limiting structure 20 and the second limiting structure 30 can also be arranged in appropriate positions according to the flipping path of the first binding structure 11 or the second binding structure 12 and according to the structure of the first binding structure 11 and the second binding structure 12 to limit the flipping of the first binding structure 11 or the second binding structure 12.

[0071] Please also read Figure 1 and Figure 2The specific structure of the rigid wearable article 10 can be designed according to actual needs. For example, in some optional embodiments, the first binding structure 11 includes a posture limiting rod 111 and a leg strap 112. The posture limiting rod 111 is made of a rigid material, and the posture limiting rod 111 is rotatably matched with the pivoting portion 40. The leg strap 112 is arranged on the posture limiting rod 111 to bind the posture limiting rod 111 and the legs of the human body together. Of course, the first binding structure 11 can also adopt other suitable structural designs, and is not limited to this example. The second binding structure 12 includes a support plate 121, an inner plate 122 and an outer plate 123, which are all made of rigid materials. The inner plate 122 and the outer plate 123 are respectively arranged on opposite sides of the support plate 121, and the inner plate 122 and the outer plate 123 are connected to each other through a second strap 124. The inner plate 122 and the outer plate 123 cooperate to provide support for the side of the ankle joint. The inner plate 122 is located on the side of the ankle joint facing between the two legs, and the outer plate 123 is located on the side of the ankle joint facing outside the two legs. The support plate 121, the inner plate 122, the outer plate 123 and the second strap 124 are arranged around the foot of the human body, so as to cooperate to restrict at least part of the foot of the human body within the second binding structure 12, and the pivot portion 40 and the groove 13 are arranged on the outer plate 123. Of course, the second binding structure 12 can also adopt other suitable structural designs, not limited to this example.
