Definitions

  • the invention relates to a knee protector with a box-shaped basic body enclosing the front knee region and forming a padding for the front knee region.
  • Knee protectors of the above type are described in the research report Fb 655, publication series of the Federal Institute for Occupational Safety and Health. Such knee guards are used to protect the knees during kneeling activities and are worn, for example, by miners, tilers when laying floor slabs or gardeners. In terms of their function, the well-known knee pads are pillows that cover the knee as well as possible.
  • the invention is based on the problem of designing knee protectors of the type mentioned at the outset in such a way that the knees are subjected to as little stress as possible by compressive forces when kneeling and which restrict the mobility of the knee joints as little or not as possible when walking upright.
  • the base body has a cup-shaped support surface for supporting the shinbone below the knee joint and above the support surface a recessed area which receives the kneecap freely movable when the leg is not bent.
  • This design allows the kneecap to move in the recessed area as long as it is not fixed by the supporting forces when kneeling. This enables the kneecap to move outwards and downwards when the respective knee joint buckles, as with the leg not provided with a knee protector.
  • kneeling the kneecap is subjected to considerably less stress because it is in a lateral position within the knee protector and a large part of the supporting forces are introduced directly into the thigh bone via the supporting surface according to the invention and laterally via the shinbone bump.
  • the recessed area also means that the leg in the area of the front knee area is well ventilated, which counteracts skin inflammation. When walking with knee pads on, the recessed area does not cause any discomfort in the area of the joint.
  • the cup-shaped support surface and the recessed area continue to bring about an inevitable correct alignment of the knee protector on the leg and therefore require lower holding forces, so that secure attachment without obstructing blood circulation is possible.
  • the knee protector has a floor support on its front, through which the lower leg of a kneeling person is oriented from the knee upwards towards the foot.
  • the slanted alignment of the lower legs also makes it easier for a kneeling person to work in the floor area in front of them.
  • the knee protector makes it possible to assume two different positions in the knees if the floor support has a tipping edge that runs transversely to the knee protector and a stable support is provided by different contact surfaces in two differently inclined positions.
  • a particularly advantageous development of the invention consists in the fact that the floor support has two lateral support surfaces and in between one that does not touch the floor, has elastically deformable knee support area.
  • the side parts of the knee protector increasingly press against the knee from the side when the knee is increasingly supported between the lateral support surfaces when kneeling. This leads to an increase in the support surface and, in turn, to a lower pressure load, which is also advantageous for the blood supply to the skin.
  • a further relief of the knee by increasing lateral support forces can be achieved if the floor support has a floor support at its foremost end at a distance from the tipping edge and the area in between runs at a distance from the floor.
  • knee protector consists of an outer shell and an insert body inserted therein and having the padding. This makes it possible to use differently damping insert bodies for different loads, so that the knee protector according to the invention is particularly versatile.
  • the insert body is shaped according to the individual requirements of the user. In such a case, it is possible to design the knee protector from an orthopedic point of view and to correct incorrect posture by the user.
  • the support via the shinbone can take place to an even greater extent if the support surface for the shinbone has a support extension extending up to the ankle.
  • the support via the shin can be selected smaller or larger as required if the support extension is detachably connected to the knee protector.
  • the kneeling person reaches a particularly stable position when kneeling when the support extension near its ankle-side end has a support that reaches to the ground when kneeling.
  • the knee protector shown in FIG. 1 consists of a base body 1 made of an elastic material, for example polyurethane.
  • This base body 1 has a bowl-shaped support surface 2 in the lower region, which is placed against the shin from below under the knee when the knee protector is attached. Holding straps 3, 4 make it possible to fasten the base body 1 in this position on the lower leg below the knee.
  • the base body 1 In front of the support surface 2, the base body 1 has a recessed area 5 which receives the kneecap when in use. This recessed area 5 jumps back so far and is dimensioned that the patella can move as freely as possible when walking upright.
  • the base body 1 On its left-hand side as seen in FIG. 1, the base body 1 has a floor support 6, with which the knee protector is supported on the floor when kneeling.
  • This floor support 6 is provided with a transverse tipping edge 7, to which a front floor support 8 extends at a distance and at a greater offset.
  • FIG. 2 illustrates that the recessed area 5 runs much closer to the floor support 6 than the support surface 2. Furthermore, it can be seen that the floor support 8 is higher than the tilting edge 7. If the base body 1 assumes a forward-tilted position when kneeling, then it stands on the floor with the front floor support 8 and the tipping edge 7, while an area 9 in between has no contact with the floor. If the patella presses down in this area, then side parts 10 of the base body 1 lie against the knee area with increasing force from the side. A Velcro strip piece 11 is also shown in FIG. 2. This and a further Velcro strip piece attached on the opposite side make it possible to fasten the base body 1 to Velcro areas of the user's trousers instead of the holding straps 3, 4 shown in FIG.
  • FIG. 3 shows that the floor support in this area has two lateral support surfaces 12, 13, between which a knee support area 14 runs without contact with the floor.
  • FIG. 3 also shows that the base body 1 can be formed from an outer shell 15 and an insert body 16 inserted therein. Then it is possible Shaping insert body 16 individually, similar to a shaped sole.
  • FIG. 4 schematically shows a kneeling person 17 with a knee protector 18 designed according to the invention. It can be seen that this knee protector 18 only stands on the floor positioned at 19 with the base support 8 and the tipping edge 7. As a result, the lower legs 20 of the person 17 rise towards the rear, so that the feet 21 can take a comfortable posture and no greater forces act on them.
  • a support extension 22 is shown in dash-dotted lines, which extends along the shin and may have a support 23 reaching to the floor 19 near the ankle. This support extension 22 can either be fixed to the knee protector 18 or releasably connected to it.
