Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. It is to be understood that the embodiments described are only a few embodiments of the present application and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

The embodiment of the application provides a lower limb support, can be fixed to the lower limbs of the wearer through the mode of wearing to support, protection, posture correction or other auxiliary function are provided to the lower limbs of the wearer. For example, the lower limb support may be a sport supporter for protecting a knee joint portion of a wearer, the lower limb support may also be a portion of an outer wearing skeleton to provide auxiliary power for the wearer during a sport, and the lower limb support may also be a medical orthosis to correct a posture of the wearer with partial lower limb dyskinesia or lower limb injury, which is not limited in this embodiment.

Referring to fig. 1, fig. 1 is a schematic view of a part of a lower limb support according to an embodiment of the present disclosure. In the following, the technical solution provided by the embodiment of the present application is further explained by taking the following limb support as an example for performing posture correction on the lower limb of the wearer:

as shown in fig. 1, the lower limb brace may include a first linkage assembly 100, a joint assembly 200, and a second linkage assembly 300. Illustratively, the first coupling assembly 100 may be secured in a wearable manner to the thighs of the wearer. The second connecting assembly 300 can be connected and fixed with the lower leg of the wearer in a wearing manner. The first linkage assembly 100 and the second linkage assembly 300 are rotatably coupled by the joint assembly 200.

Further, when the lower limb brace is worn about the lower limb of a wearer, the joint assembly 200 may be positioned substantially adjacent the knee joint of the wearer. When the thigh and the calf of the wearer rotate relatively with the knee joint as a rotating fulcrum, the first connecting component 100 and the second connecting component 300 rotate relatively with the joint component 200 as a rotating fulcrum, so that the lower limb support can correct the posture of the lower limb of the wearer in the movement process of the wearer.

As shown in fig. 1, the second connection assembly 300 may include a second support mechanism 31 and a second fixing member 32. The second support mechanism 31 plays a main role in supporting and fixing the lower leg, and is rotatably connected with the first connecting assembly 100 through the joint assembly 200. The second fixing member 32 is used to fixedly couple the second supporting mechanism 31 to the thighs of the wearer by wearing.

The second support mechanism 31 may be made of a rigid material to provide a primary support for the lower leg of the wearer. For example, the second supporting mechanism 31 may be any one or a combination of more than one of rigid plastic, composite material and metal. Alternatively, the second supporting mechanism 31 may be a material with certain flexibility, so that the second supporting mechanism 31 can deform within a preset range after receiving an external force, so as to avoid that the deformation of the second supporting mechanism 31 is too large to support and fix the lower leg of the wearer.

Next, taking the chest side of the torso of the wearer as the front side, the back side as the back side, and the left and right sides as the left and right sides, respectively, the specific scheme of the second supporting mechanism 31 in the embodiment of the present application will be further explained in conjunction with the wearing condition of the second supporting mechanism 31.

In some embodiments, the second supporting mechanism 31 may include a long rod-shaped first rod, and the first rod may be fixed to the left or right side of the wearer's lower leg by the second fixing member 32, for example, the second fixing member 32 may include a strap, and the wearer's lower leg may be directly strapped and fixed to the first rod by the strap.

Alternatively, as shown in fig. 1, the second support mechanism 31 may include a first support rod 311 and a second support rod 312. The first support bar 311 and the second support bar 312 are disposed opposite to each other. In actual use, the first support bar 311 and the second support bar 312 are respectively located on the left and right sides of the lower leg of the wearer. The first support rod 311 and the second support rod 312 may have the same shape and size, may also have the same shape and size, and may also have different shapes and sizes.

Referring to fig. 2, fig. 2 is a schematic structural view of a second connecting assembly of a lower limb support according to an embodiment of the present disclosure. Next, taking the second supporting mechanism 31 including the first supporting rod 311 and the second supporting rod 312 as an example, the specific configuration of the second fixing member 32 in the embodiment of the present application will be further explained and explained.

As shown in fig. 2, the first support bar 311 and the second support bar 312 may be connected by the first fixing member 33. In particular use, the first securing component 33 conforms to the front surface of the lower leg of the wearer. At this time, the first support bar 311 and the second support bar 312 are attached to the left and right sides of the lower leg of the wearer. The wearer's lower leg may move backward to exit the semi-enclosed space surrounded by the first support bar 311, the first fixing member 33, and the second support bar 312, or the wearer's lower leg may move forward to enter the semi-enclosed space surrounded by the first support bar 311, the first fixing member 33, and the second support bar 312.

The first fixing member 33 may be a strap, or may be a component or assembly that can be attached to the front surface of the lower leg of the wearer, such as another flexible fixing member, which is not limited in the embodiment of the present application.

As shown in fig. 2, in order to fix the first support bar 311 and the second support bar 312 on the lower leg of the wearer, one end of the second fixing member 32 is detachably connected to the first support bar 311, and the other end of the second fixing member 32 is detachably connected to the second support bar 312, so that the first support bar 311, the second fixing member 32, the second support bar 312 and the first fixing member 33 can enclose a closed structure around the lower leg of the wearer.

When wearing specifically: the first fixing member 33 is attached to the front side of the lower leg of the wearer. The first support bar 311 and the second support bar 312 are attached to left and right sides of the lower leg of the wearer, respectively. The second fixing component 32 is connected to the first supporting rod 311 and the second supporting rod 312 at the same time, so that the second fixing component 32 is attached to the rear surface of the wearer, and at this time, the first supporting rod 311, the first fixing component 33, the second supporting rod 312 and the second fixing component 32 are matched to form a closed ring structure to be sleeved on the lower leg of the wearer, thereby realizing the connection between the second connecting component 300 and the lower leg of the wearer. When it is desired to remove the second connecting assembly 300 from the lower leg of the wearer, the second connecting assembly 300 can be removed from the lower leg of the wearer after the second fixing member 32 is detached from at least one of the first support rod 311 and the second support rod 312.

The second securing member 32 may comprise a lower leg strap. The two ends of the calf bandage in the length direction can be detachably connected and fixed with the corresponding first support rod 311 or second support rod 312 in a binding, sticking, hooking or other detachable connection mode.

In some embodiments, to increase the contact area of the second securing component 32 with the wearer's lower leg, the second securing component 32 may further include a body element 321 (such as a pad) that fits over the lower leg strap, the width of the body element 321 being greater than the width of the lower leg strap. It will be appreciated that by increasing the overall contact area of the second securing member 32 with the lower leg of the wearer, the pressure applied by the lower leg strap across the lower leg of the wearer can be reduced, thereby improving the comfort of the wearer. On the other hand, increasing the contact area between the second fixing member 32 and the lower leg of the wearer can also increase the friction between the second fixing member 32 and the lower leg of the wearer, thereby improving the stability of the second connecting module 300 when it is worn on the lower leg of the wearer.

Referring to fig. 3, fig. 3 is a schematic view illustrating a second fixing member of the lower limb support of fig. 1 in an unfolded state.

In another embodiment of the calf strap, in order to increase the contact area of the second fixing part 32 with the wearer's calf, the calf strap may include a main unit 321 and connecting units 322 which are integrally formed, one connecting unit 322 is provided at each end of the main unit 321 in the length direction, the width of the connecting unit 322 is smaller than that of the main unit 321, and each connecting unit 322 is detachably connected with the second supporting mechanism 31. It can be understood that, in this embodiment, through with main body unit 321 and connecting unit 322 integrated into one piece, can reduce the part quantity of second fixed part 32, and then not only can reduce the dismouting degree of difficulty of second fixed part 32 in the dismouting in-process, can also reduce the work load when second fixed part 32 is clean through reducing the part quantity that needs to be clean, finally reaches the effect that reduces the holistic clean work load of lower limbs support.

Referring to fig. 4 and 5, fig. 4 is a sectional view taken along the P-P direction of the lower limb support of fig. 3 in an unfolded state of the second fixing member. Fig. 5 is a partial enlarged view of the second fixing member of the lower limb support of fig. 4 at the X-position.

As shown in fig. 4 and 5, in order to improve comfort when the wearer wears the second link assembly 300, the lower leg strap may include an elastic buffer layer 323 for forming the body unit 321 and the link unit 322. Furthermore, when the calf strap is tied to the calf of the wearer, the elastic buffer layer 323 can generate certain elastic deformation so as to avoid the discomfort and even the bruise of the wearer caused by the tight tying of the calf strap.

In order to avoid the elastic deformation of the calf strap at will and thereby affect the stability of the calf strap when it is attached, the calf strap may be configured to be elastically deformable only in the thickness direction.

Illustratively, as shown in FIG. 4, the elastic cushioning layer 323 is provided with a flexible facing 324 along at least one side of the thickness of the calf strap. It will be appreciated that flexible facing 324 has a flexible ability to deform without elastic ability, such that flexible facing 324 can be adapted to conform to the shape of the wearer's lower leg, but cannot elastically deform. Therefore, the calf bandage can be elastically deformed only in the thickness direction through the elastic buffer layer 323 to play a role in buffering, but cannot be elastically deformed in the length direction to ensure that the length of the calf bandage is not changed, and further the calf bandage is prevented from loosening relative to the calf of a wearer. Therefore, the calf strap provided by the embodiment of the application has the advantage of stable binding.

In practical applications, the elastic buffer layer 323 may be provided with a flexible surface layer 324 on a side facing towards the wearer's lower leg in the thickness direction of the lower leg strap, or the elastic buffer layer 323 may be provided with a flexible surface layer 324 on a side away from the wearer's lower leg in the thickness direction of the lower leg strap, or both sides of the elastic buffer layer 323 in the thickness direction of the lower leg strap are provided with flexible surface layers 324 as shown in fig. 4.

It is also understood herein that when the lower leg strap includes the integrally formed body unit 321 and the connecting unit 322, any one of the body unit 321 and the connecting unit 322 includes the elastic buffer layer 323 and the flexible cover 324, and the rest should also include the elastic buffer layer 323 and the flexible cover 324. If the calf strap includes the main body unit 321 and the connecting unit 322 which are formed separately, only the main body unit 321 may include the elastic buffer layer 323 and the flexible surface layer 324, or both the main body unit 321 and the connecting unit 322 may include the elastic buffer layer 323 and the flexible surface layer 324, which is not limited in this embodiment of the present application.

As shown in fig. 3, in order to improve the fit of the main body unit 321 to the wearer's calf, the width of the main body unit 321 is gradually reduced from the middle to both ends along the length direction of the calf strap to match the wearer's calf.

Illustratively, the upper edge of the body unit 321 is an arc shape that protrudes upward, and the lower edge of the body unit 321 is an arc shape that protrudes downward. It can be understood that, if the main body unit 321 adopts a square structure, that is, the width of each part of the main body unit 321 is equal, after the calf strap is bound and fixed, the fitting degree of the main body unit 321 and the calf of the wearer is lower, that is, the number of the parts of the main body unit 321 tilted relative to the calf of the wearer is more, and especially in the process of the wearer's movement, the calf strap is easy to loosen from the calf of the wearer along with the dynamic change of the muscle of the calf. And in this application embodiment, the upper edge and the lower edge of main part unit 321 are the arc, so when the shank bandage was tie up, main part unit 321 can be better with the muscle laminating of wearer's shank to stability when the shank bandage was tie up improves.

To improve stability of the lower leg strap when worn on the wearer's lower leg, the lower leg strap may be configured to fit to the side of the wearer's calf proximate the knee joint. It will be appreciated that the calf is convex outwardly relative to the axis of the calf; when the human body stands, the cross-sectional area of the calf close to the knee joint is gradually increased from top to bottom, and the cross-sectional area of the calf far away from the knee joint is gradually decreased from top to bottom. Therefore, when the lower leg bandage is attached to one side, close to the knee joint, of the calf bandage, the lower limb support can be prevented from loosening due to the fact that the lower leg bandage slides downwards in the process that a wearer stands or walks.

Illustratively, the body unit 321 is configured to be able to bend to form a preset curved surface, which is inclined in a direction away from the joint assembly 200 toward a direction away from an axis line of the preset curved surface. The technical solution of the embodiment of the present application is further explained below with reference to the standing state of the wearer.

As shown in fig. 1, when the lower limb brace is worn on the lower limb of a wearer, the joint assembly 200 is positioned at the knee joint of the wearer and the body unit 321 is positioned at the lower leg of the wearer, so that the joint assembly 200 is positioned above the body unit 321. Here, the inclination of the predetermined curved surface in a direction away from the joint assembly 200 toward a direction away from the axis line of the predetermined curved surface may be understood as: the predetermined curved surface is inclined in a direction from the top to the bottom in a direction away from the axis of the lower leg (i.e., outward).

The preset curved surface can be a part of the side wall surface of a virtual circular truncated cone. Since the cross-sectional area of the calf on the side close to the knee joint is gradually increased from top to bottom, a part of the calf close to the knee joint can be regarded as a part of the outer side of the virtual round platform. Therefore, the main body 321 can be adhered to the surface of the calf near the knee joint by bending to a predetermined curved surface,

of course, it can be understood that, since the calf muscles of different wearers have slightly different shapes, the main body unit 321 can be adaptively deformed according to the calf muscle shape after being attached to the calf, that is, the main body unit 321 bent to the preset curved surface can be slightly adaptively deformed based on the preset curved surface shape after being attached to the calf of the wearer, so that the main body unit 321 can be attached to the calf of the wearer.

The manner in which the main body unit 321 and the connection unit 322 of the lower leg band are integrally formed is explained further below with reference to the manufacturing method:

first, an elastic cushioning material having a large area and a flexible fabric having a large area are prepared. Then, covering a flexible fabric on at least one side surface of the elastic buffering material, and attaching and fixing the elastic buffering material and the flexible fabric to obtain a first intermediate. Next, the first intermediate body is cut into a plurality of calf straps, and the main body unit 321 and the connecting unit 322 of the calf strap are integrally formed by cutting the first intermediate body, at this time, the elastic buffer material forms the elastic buffer layer 323, and the flexible fabric forms the flexible surface layer 324.

The elastic buffering material and the flexible fabric can be bonded by using an adhesive. Optionally, the elastic buffer material and the flexible fabric may be attached by hot press attachment or the like, which is not limited in the embodiment of the present application.

As shown in fig. 5, in order to make the edge of the lower leg strap more neat and beautiful, a circumferential edge 326 can be sewn along the outer contour line of the lower leg strap. In addition, hem 326 wraps the edges of elastic cushioning layer 323 and flexible facing 324 to prevent adhesive glue at the edges of elastic cushioning layer 323 and flexible facing 324 from falling off, thereby causing damage to the calf strap.

In order to improve the wearing comfort of the lower leg bandage, the air permeability of the lower leg bandage can be improved. For example, the elastic buffer layer 323 can be a styrene-butadiene rubber sponge material, and the flexible surface layer 324 can be a waterproof and breathable surface layer. Wherein, the butadiene styrene rubber sponge has better air permeability and elasticity, and the waterproof breathable fabric has the characteristic of ventilation. Therefore, the problem that the crus of the wearer cannot be ventilated and radiated in time at the attachment position of the crus bandage, so that the crus of the wearer has stuffy feeling and even sweats can be prevented. On the other hand, the waterproof breathable fabric has the characteristic of good waterproof effect, so that sweat of a wearer or cleaning liquid in the process of cleaning the lower leg bandage is not easy to permeate into the lower leg bandage to damage the elastic buffer layer 323.

Alternatively, the elastic buffer layer 323 can be made of yellow sponge, neoprene sponge, or silicone. Further, when the elastic buffer layer 323 is made of airtight materials such as silica gel, a plurality of air holes may be formed at intervals on the elastic buffer layer 323, so that the whole formed by the elastic buffer layer 323 and the flexible surface layer 324 has the characteristics of water resistance and air permeability.

As shown in fig. 5, the connection unit 322 may be provided with an adjustment unit 325, and the adjustment unit 325 may adjust a connection position of the connection unit 322 with the first support bar 311 and/or the second support bar 312. Furthermore, the parts of the calf strap with different lengths can be fixedly connected with the first support bar 311 and/or the second support bar 312, so that the size of the enclosed space enclosed by the calf strap and the second support mechanism 31 can be adjusted, and finally the second connecting assembly 300 can be suitable for being worn on the wearers with different calf diameters.

The adjusting unit 325 may be a plurality of hooks disposed on the connecting unit 322, and the hooking members are disposed on the first supporting rod 311 and/or the second supporting rod 312, so that different hooks may be hooked and fixed to the hooking members, so that the connecting unit 322 may be selectively connected and fixed to the first supporting rod 311 and/or the second supporting rod 312 through different portions.

It is understood that the specific structure of the adjusting unit 325 is not limited in this embodiment of the application. For example, the adjusting unit 325 may further include a hook and loop fastener instead of the hook, one surface of the hook and loop fastener is fixedly connected to the connecting unit 322 by welding, sewing, or the like, and the other surface of the hook and loop fastener can be adhered to the flexible surface layer 324.

In one embodiment of the adjusting unit 325, the adjusting unit 325 may include a hook and loop fastener or a hook and loop fastener, and the hook and loop fastener or the hook and loop fastener matched with the adjusting unit 325 is disposed on the first supporting rod 311 and/or the second supporting rod 312, so that the connecting unit 322 can be selectively connected and fixed with the first supporting rod 311 and/or the second supporting rod 312 through different portions.

In another embodiment of the adjusting unit 325, as shown in fig. 5, the adjusting unit 325 may include a hook and loop fastener surface, and the side of the flexible surface layer 324 opposite to the elastic buffer layer 323 has piles, so that the adjusting unit 325 can be adhered to the piles of the flexible surface layer 324 through the hook and loop fastener surface. In practical application, a hole for the connection unit 322 to pass through may be provided on the second support mechanism 31, so that the connection unit 322 can pass through the hole of the second support mechanism 31 and then be bonded and fixed with the flexible surface layer 324 through the magic tape puncturing surface serving as the adjustment unit 325, thereby binding the calf strap on the second support mechanism 31.

As shown in fig. 1, the first support bar 311 and the second support bar 312 may be provided with a strap connecting member 34, and the strap connecting member 34 may be provided with a fixing hole 341 as a hole for the connection unit 322 to pass through on the second support mechanism 31. The free end of the connection unit 322 passes through the fixing hole 341 and then is folded back to be adhesively fixed on the flexible surface layer 324, so that the connection unit 322 is fixed on the strap connecting member 34.

It can also be understood that, in a specific use, only one connection unit 322 may be provided with the hook and loop fastener surface. For example, the connection unit 322 connected to the first support bar 311 is set as a first connection unit, the connection unit 322 connected to the second support bar 312 is set as a second connection unit, and the free end of the first connection unit is provided with a hook and loop fastener surface. When in use: first, the free end of the second connection unit is folded back at the second support bar 312; then, the free end of the first connection unit is folded back at the first support rod 311; and finally, the magic tape sticking surface at the free tail end of the first connecting unit is fixedly bonded with the flexible surface layer of the second connecting unit.

Alternatively, two connecting units 322 may be provided with a hook and loop fastener sticking surface, so that the free end of each connecting unit 322 is folded back at the corresponding first supporting rod 311 or second supporting rod 312 and then is fixed to the lower leg strap by the hook and loop fastener sticking surface. Furthermore, the free end of each connection unit 322 may be adhered and fixed to itself after being folded back, may be adhered and fixed to the main body unit 321, and may be adhered and fixed to another connection unit 322, which is not limited in this embodiment of the present application.

As shown in fig. 1, the strap connector 34 may be movably mounted on the corresponding first support bar 311 and/or second support bar 312. For example, the strap connecting member 34 may be rotatably connected to the corresponding first supporting bar 311 and/or second supporting bar 312 by a rotating connecting member 35 such as a rotating shaft, a pin, a rivet, or a stud. Therefore, the lower leg band fastened to the band connecting member 34 can be moved within a certain range, so that the specific fastening position of the lower leg band can be finely adjusted according to the wearer of different leg types.
