Description

Work leg guards

The invention relates to a leg guard especially for the protection of the knee and the lower leg of a leg.

Knee pads for working in a kneeling position are well known. So knee protectors are currently on the market, which are attached by means of rubber bands above and below the knee or in the popliteal fossa on the leg. If the knee pads are used during use, the rubber bands will regularly slip, resulting in a poor fit and uncomfortable wearing comfort. In particular, the knee protectors on the market, which are firmly attached to the knee, cause transpiration in the area of the knee, which can result in chafing of the skin. This makes it difficult to wear over a longer period of time or makes it almost impossible to wear over a longer period of time. The need for constant corrections of the seat of the knee pads are a consequence.

The object of the invention is to provide an improved working leg protector.

This object is achieved by means of a work leg protector according to claim 1, a use of a work leg protector according to claim 19, a method according to claim 20 and a method for producing a work leg protector according to claim 22. Advantageous embodiments are given in the corresponding subclaims.

It is proposed a leg protector with at least a first guard area and at least a second guard area and at least one holding means for attaching the Arbeitsschoners on one leg. The first guard area is configured at least for placement in the region of a knee, and the second guard area is designed at least for placement in the region of a tibia. At least the first guard area and the second guard area are integrally formed and form a substantially rigid shield, wherein the holding means is arranged only on the second guard area.

In the following, the term leg guards for leg guards is used, which are mainly used for craft activities. In particular, the Arbeitsbeinschoner provides a working device, for example for tilers, screed, parquet and

eesrrATiGUNGSKOPt Laminator, roofers or masons dar. Also, the term work saver schooner may include schooner, which also protect at least parts of the foot and / or thigh.

The term "one-piece" is to be understood as meaning that the first guard area and the second guard area are material-connected and, in particular, designed in one piece.

The proposed invention has the advantage that in addition to the knee and the tibia is protected by means of the working leg protector. In particular, when working on a staircase, for example, or in situations in which it is unavoidable to kneel on an edge, protection of the shins is advantageous. Furthermore, it is advantageous that, when working on a wet or moist floor, a wetting of the leg gown is avoided. The largely rigid connection of the individual guard areas has the advantage that a seat correction of the entire leg protector is easy, for example, by pulling or pushing on a part of the leg protector to bring the complete leg rest in the correct position.

In a further variant, the first guard area and the second guard area are arranged offset to one another. In one embodiment, the first and the second leg protectors are arranged at an angle to each other.

In particular, the angle or the offset is arranged above the uppermost holding means, preferably about 0.5 centimeters to about 10 centimeters, more preferably about 2 centimeters to about 5 centimeters. Furthermore, the angle is preferably arranged largely in the middle, relative to the longitudinal axis of the working leg protector. More preferably, when the leg guard is worn on the leg, the first saver area tilts slightly away from the leg. Furthermore, the first guard area preferably has a curvature in at least one section towards the leg, so that in a longitudinal section it describes a curve towards the leg. Furthermore, an embodiment provides that the first guard region extends in a longitudinal section at least in one section in a straight line, in particular parallel to a section of the second guard region. In particular, in one embodiment, an offset is a step or a curved transition between the first and second leg protectors. The inner side of the first guard region has in a longitudinal section at the upper edge a distance from a straight line, on which at least a portion of an inner side of the second guard region is arranged, from about 10 millimeters to about 50 millimeters, preferably about 20 millimeters to 35 millimeters, Farther preferably about 25 millimeters to about 30 millimeters. The spacing of the first saver area from the leg results in increased wearing comfort, since back ventilation of the working leg saver is possible, especially when standing. Also, by the spacing of the second guard area when standing and going a chafing of the Arbeitsschoners knee avoided. The leg protector is preferably designed such that it does not stick to the knee at a knee circumference of, for example, about 42 centimeters to about 45 centimeters and a patellar protuberance over the tibial bone of about 0.5 centimeters to about 2 centimeters Knee abuts.

Fig. 1 shows a leg guard 1 in a front view. The leg protector 1 has a first guard area 2 and a second guard area 3, which are largely rigidly and integrally connected to each other. The first guard area 2 comprises a damping element 4, which has a notch 5. The notch 5 is conical, so that the damping element 4 is harder in an upper region 6 than in a lower region 7. The working leg protector has a length 8 of about forty-two centimeters and a width 9 of about seventeen centimeters. In one embodiment, the damping element 4 has an anti-slip surface, for example a structured surface, which reduces gliding on a smooth and / or wet surface.

Furthermore, the leg protector in the second guard area 3 guides 10, 11, 12, 13, 14 and 15, in which holding means can be introduced. The guides 10, 12, 13 and 15 are arranged at an angle to a transverse axis 16, 17. The guides 10 and 12 have approximately an angle α of 5 ° to 10 °, preferably about 8.38 ° and the guides 13 and 15 have approximately an angle ß of 5 ° to 10 °, preferably about 8.95 ° ,

Fig. 2 shows the Arbeitsbeinschoner in a view from below. It can be seen that this has a curvature 18, which can rest on one leg. In particular, this curvature is provided in one embodiment with a pad, not shown here.

The wear part 44 is in particular releasably attached by the damping element 4, to allow replacement of the wear part 44. Preferably, the wear part 44 has a puncture resistant material. Further preferably, the wear part 44 is a puncture protection.

10 shows an embodiment of a puncture protection 38, which is introduced into a tool 39. The tool is closed in a subsequent step not shown here and filled with PU foam. Spacers 40 keep the puncture protection 38 largely in the middle, so that it is almost completely foamed. In the area of distance ter 40 there is no foam around. The puncture protection 38 is thus seen in the final product, whereby appealing appearance of the leg protector 1 is achieved. It is also provided in one embodiment that the non-foamed part of the puncture protection is blinded.

Fig. 11 shows the section Xl-Xl of a leg guard 1, which was made in the tool of Fig. 10. It can be seen that the puncture protection 38 is surrounded by PU foam 41. In a further embodiment, it is provided that the second guard area 3 also has a stab guard 38.

FIG. 12 shows a further embodiment of an operating leg protector 1. The working leg protector 1 has claws 42 in the second protector area 3, which, for example, can prevent slipping when a user kneels on an edge or a step.

FIG. 13 shows a sectional view of the section XIII-XIII of FIG. 12. It can be seen that the first guard area 2 is offset from the second guard area 3. Furthermore, a step 45 is provided which represents a transition from the first guard area 2 to the second guard area 3. The first guard area 2 is offset by a distance 43 from about 20 millimeters to about 1 centimeter, preferably from about 20 millimeters to about 40 millimeters, more preferably about 30 millimeters.

Furthermore, the claws 42 can be seen in Fig. 13, which are integrally connected in this embodiment with the second guard area.
