Definitions

  • the present invention relates to an ergonomic orthosis adapted to be attached to the leg of a person that allows the wearer to kneel without causing extreme and / or prolonged joint stress in the knee, ankle, back or leg. basin.
  • knee pads during work performed in these kneeling positions.
  • Such kneepads only improve the contact with the ground, including a supple support at the knee, which protects the tibial tuberosity and prevent injuries in case of uneven ground.
  • they do not have any action on the hyper pressure inside the knee (in particular in the patella, menisci and patellar tendon), the hyper flexion or hyper extension of the ankle, according to the chosen position, nor on the hyper flexion of the toes and in particular the metacarpophalangeal joints that will suffer if this position is maintained.
  • knee pads are often held by elastics passing to the back of the calf. Such links tend to create friction and interfere with venous returns and are therefore uncomfortable.
  • the document US 6,415,441 describes another protective device having a shell that surrounds the shin by stopping below the knee, which is attached by straps around the calf and is supported by a small booster at its front end. Assuring, certainly, a better stability of the wearer than the pad of the previous document, this device has the disadvantage of causing shear inside the knee and to put the toes in hyper flexion, to exert an extension stress also at the ankle and therefore present discomfort in use. In addition, due to the small dimensions of the bearing surface, a forward tilting may occur with the risk of unbalancing the wearer.
  • the object of the invention is to provide an ergonomic leg support orthosis that overcomes the disadvantages of the aforementioned devices, in particular that allows to relieve joint and muscle forces during the bending of the leg, to avoid the appearance trauma in the kneeling position, improve comfort when working on the ground, relieve handling work during the installation of materials or materials and protect the leg of any blows.
  • Another object of the invention is to provide an ergonomic leg support orthosis which makes it possible to perform work in a kneeling position, while releasing the joints at the level of the leg, foot, pelvis or back, and allowing the user to adopt a natural body posture, even when the kneeling position is maintained over time.
  • Another object of the invention is to provide an ergonomic support orthosis for the leg to perform, comfortably and by limiting the effort, work requiring support on the ground of one or both knees, while allowing the user to return to the standing position without effort.
  • Another object of the invention is to provide an ergonomic leg support orthosis that makes it possible to avoid reaching the extreme amplitudes of extension and flexion of the joints of the lower limbs, at the level of the knee, the ankle and the ankles. toes.
  • Another object of the invention is to provide an ergonomic leg support orthosis that allows a comfortable, stable kneeling position, requiring no action of support of the feet and hands.
  • Another object of the invention is to provide an ergonomic support orthosis for the leg allowing a good comfort in use, while being able to be made economically.
  • an ergonomic leg support orthosis comprising a main body which is made to have a length substantially equal to at least the distance between the patella and the tibial tuberosity, the lower part of the body forming a base substantially flat and intended to support the ground and the upper part having a gutter for housing the leg, and means for attaching to the carrier, because said body has in its rear portion a rear height substantially equal to the length of the foot of the wearer, after deduction of the height of the toes, and, in its front part, a front height which is substantially equal to or greater than said rear height, and in that said gutter has a profile designed so as to match the shape of the shin and lower knee.
  • the front portion of the profile of the gutter comprises at least a first clearance having substantially the shape of the lower part of the knee and, preferably, also a second clearance for accommodating the tibial tuberosity.
  • the gutter may, in addition, include a portion slightly inclined downwards to form a bearing zone for the tibial crest.
  • the body of the orthosis is high enough to reduce the amplitude of the flexion of the knees during the transition from standing to kneeling position, thereby relieving the joint and / or muscle constraints of the knee, foot , thigh and leg.
  • the hips remain free allowing great mobility of the bust, in all directions, the movements are not held by pain caused by the direct contact of the leg with the ground or when using the devices of the state of the art.
  • This height is limited, however, in the rear part of the body, to allow the toes to support the ground when the person wearing the orthosis wants to kneel or stand up.
  • This well-defined height of the main body makes it possible to relieve the efforts muscles by limiting the flexion height for a kneeling on one or two legs, but also during the work of handling, gardening, etc., while allowing to generate good postures.
  • the main body is high enough to protect the wearer's leg and clothing from water, dirt and pollutants during the work performed.
  • the length of the orthosis is greater than the distance between the patella and the tibial tuberosity.
  • the minimum length of the orthosis is between the bottom (the base) of the tibial tubercle and the anterior aspect of the thigh measured in a kneeling position on the orthosis when the knee is bent at 90 ° to the knee. horizontal.
  • the orthosis of the invention makes it possible to relieve and eliminate the tensions and pains in the joints of the foot, the ankle, the tibial tuberosity, the knee (in particular the patella, the menisci, the patellar tendon). , to release the movement of the hips, removes the constraint of the fibular nerve at the level of the fibula head, allows to respect the physiological lordosis in the work of handling, protects the lumbosacral hinge, etc.
  • the front portion of said profile comprises a first clearance made so that its depth and / or its shape makes it possible to house the lower part of the knee. This makes it possible to create a space for receiving the patella in order to prevent it from being crushed and to relieve the support on it.
  • said clearance extends towards the front of the orthosis by a connection or by a chamfer connected to said base via a front face which forms an acute angle with the latter.
  • a chamfer or connection allows to leave the patella free during the various movements of extension of the knee and provide support to the patellar tendon and / or the patella during a forward movement of the wearer.
  • the sloped front has the role of increasing stability when the wearer leans forward.
  • said channel has a conical shape, the base of the cone being oriented towards the front of the orthosis.
  • a conical shape of the gutter allows it to better adapt to the shape of the leg, by surrounding it with its walls sideways along the entire length of the orthosis for added stability.
  • the side walls of said channel comprise at least one lateral clearance at the knee joint.
  • This clearance made in the side walls of the gutter increases comfort, especially during intensive use of the orthosis, removing the lateral friction zones at the knee joint.
  • the orthosis of the invention comprises a seat body and means for connecting the latter to said main body.
  • Such a seat body limits the bending by a support of the thighs on a stop coming into contact with the ground.
  • the seat body is connected, fixed or removable, to the main body of the orthosis. This allows additional support at the back of the orthosis to release all the joints of the foot, ankles or knee, as well as compressions, flexions or extensions at the same, while providing rest station between two spots.
  • the bust can be kept straight or easily tilted forward until it can be supported on the ground with the hands, without exerting pressure on the joints.
  • the shape of the ergonomic support orthosis of the invention makes it possible to match the shape of the leg, especially at the level of the lower part of the knee and the tibia, and to reduce, by distributing uniformly over the length of the orthosis, the pressure usually exerted on the kneecap in the kneeling position and according to the different postures of the body.
  • the pressure when the bust is forward, the pressure is distributed over the front half of the orthosis; when the pelvis tilts towards the heels, the pressure is distributed on the back half of the orthosis; and when the bust reclines while seated on the seat body, the seat relieves pressure on the shin and completely relieves pressure on the knees. Returning to the upright position is also facilitated by tilting the bust back from the sitting position on the seat.
  • said seat body has a foot passage opening located between a support base and a seat stop. This allows, during the establishment of the orthosis around the leg, to freely slide the ankle, through the opening of the seat body, while leaving the ankle the opportunity to take different positions relative to the support offered by the lower edge of this opening of passage.
  • said main body and / or said seat body are provided with at least one comfort coating on the parts coming into contact with the leg and / or the thigh. This improves the contact with the leg and, therefore, increase the performance of the distribution of the load, as well as to ensure better comfort in use.
  • the orthosis of the invention comprises means for adjusting the height and the length of said main body and said seat body, as well as the distance between said main body and said seat body allowing their adjustment to the size of the wearer. This allows the wearer to work in the optimal position and to adopt the correct postures during the work.
  • said attachment means comprise at least one strap connecting said main body to the wearer's belt and said orthosis also comprises means for positioning said main body around the leg and / or said seat body around the foot.
  • said orthosis also comprises means for positioning said main body around the leg and / or said seat body around the foot. This allows the orthosis to be suspended at the size of the wearer, its weight can be supported by a belt, not by tight straps around the calf. This has the effect of removing any discomfort due to the tightening of the straps, while promoting the venous return and the comfort of the wearer.
