EP2865286B1 - Knee-pad and insert for knee-pad - Google Patents

Description

The invention relates to an insert according to the preamble of claim 1 and a trained for receiving the insert knee protectors.

Knee pads or knee pads are often used by people who work kneeling. At the same time, the knee protector protects the person's knee from pressure and injuries that may result from friction between the knee and the ground on which the person is kneeling.

The US 2006/0041986 A1 describes an insert for a knee protector made of an elastically deformable material and comprising an inside and an outside. The insert has on its inside a recess in which a further recess is arranged. As a result, the user's knee should be able to continue to dip into this depression in order to be better supported.

The US 5,711,029 A , the EP 0 916 370 A2 as well as the US 2003/0019006 A1 describe similarly configured inserts, namely inserts having a recess and a further recess.

Another knee protector is for example off DE 101 20 823 A1 known. The knee protector is a shell in which an insert is inserted. The shell is made of a hard material and encloses the knee. There is a pad in the shell, which deforms elastically when inserted into the shell. Also known are knee pads, in which a pad is attached to a band. An abrasion protection on the outside of the pad protects it from wear.

In the event that an inlaid pad slips, pressure could be applied to the knee that is uncomfortable for the wearer. Also, a band on the outside of the pad is attached, when kneeling exert a person uncomfortable pressure on the knee.

It is an object of the present invention to provide a knee protector of the type mentioned, so that in an easy way an improved knee protector is given with increased comfort.

This object is achieved according to the invention in that the depression has an upper region, a middle region and a lower region the recess in an upper region of the inner side is larger than in a lower region of the inner side, that the depression comprises a protrusion, and that the protrusion is arranged in the middle region of the inner side.

The curvature of the upper portion of the insert is similar to the curvature of a bent knee, wherein an edge region of the inner side of the insert is formed at least in the upper region of the insert upwardly curved. Also, the outside of the insert may be formed curved in the upper region upwards,

In another advantageous development, it is provided that the insert part is designed substantially without curvature in the lower region. For example, the lower edge of the inside is at least centrally flat.

It can also be provided that the lower region of the insert part is tapered downwards. This in turn favors the adaptation of the recess of the inside of the insert. Also, the inside of the insert may be formed symmetrically to a longitudinal axis thereof.

Another advantageous development provides that the insert comprises a pad or cushion. The outside of the insert may have a layer of neoprene or neoprene sleeve that is waterproof and / or breathable, which improves comfort. Also, the outside of the insert may include an abrasion protection.

In order to further improve the insert part, it is provided in an advantageous further development that the middle, upper and / or lower region is formed from the same or differently elastically deformable material. As a result, the adapted recess can be optimally deformed.

The inventive measures a knee protector is advantageously formed, which is characterized in that it comprises an insert (as described above), at least one holding element and a support member. The knee protector according to the invention increases the wearing comfort, since the knee is received in the adapted recess of the insert. In this case, the insert may be permanently or detachably attached to the carrier element. Also, the outside of the insert part can at least partially replace the carrier element, For example, the outside of the insert fits into a recess of the support element. The at least one retaining element serves to attach the knee protector to the knee and has, for example, hook-and-loop fasteners.

Another advantageous development provides that the support element and / or the insert on the outside comprises an abrasion protection. The abrasion protection can extend over the entire outside. Advantageously, the abrasion protection will comprise the areas of the support element or insert that come into contact with the floor when using the knee protector. The abrasion protection advantageously comprises kevlar fabric or another material that has high resistance and abrasion resistance. Also, the knee protector, the support member, the support member or the insert may have a neoprene shell that is impermeable to water and / or breathable.

Advantageous developments of the invention will become apparent from the dependent claims.
