DE10000207A1 - Foot bed has elastically deformable reinforcement insert for correcting foot in event of partial contact between shoe tread surface and ground through a correction tongue at rear foot area - Google Patents

Abstract

The invention relates to a foot-bed (1) comprising an elastically deformable reinforcement insert (2) for correcting the foot position. Said reinforcement insert (2) is configured to elastically deform the foot-bed (1) into a corrective position, whilst the bearing surface of the shoe is in partial contact with the ground. This allows the position of the foot to be corrected before the latter makes contact with the ground.

Description

The invention relates to a footbed with an elastic deformable stiffening insert for correcting the foot ßes when the tread comes into contact with this footbed equipped shoe with the floor.

A footbed of the above type is, for example, in DE 196 10 981 C1. According to the footbed this font is the stiffening insert in the midfoot area trained as a so-called pronation guide. There through you can by different stiffening inlet regulate the pronation.

As is shown, for example, by DE 33 30 178 A1, it is also known to close the heel of a shoe bevel inside the shoe. This causes the foot to tip over Appear with the paragraph first in a strong pronati position so that there is a risk of an eating is prevented. As soon as the shoe is completely covered with the Sole has ground contact, this pronation position canceled again.

Common to all previously known footbeds, that the correction of the foot through permanent elevations or depressions of the footbed, so that when Occurrence of certain parts lying in the performance area of the foot are supported. A correction from unsupported foot areas is familiar with the Means not possible. Especially with some sports certain areas of the foot are in many cases never removed supported. For example, a sprinter charges at Sprint only the forefoot and touches during  never or only with his backfoot force the ground. Cyclists also usually have only with the forefoot contact with the respective pedal.

The invention is based on the problem of a footbed trained in such a way that a correction ture of the foot is possible in areas over the Shoe no or no contact with the ground ha ben.

This problem is solved according to the invention in that the stiffening insert for elastic deformation of the Footbed in a correction position with partial floor Contact the tread of the shoe is formed.

With this design of the stiffening insert, one can correct the foot when the tread of the The bottom of the shoe in one of the be corrected touched the faraway area. Thereby a cor rectification of the foot earlier than with the known means or possible in areas that never touch the ground ben. That's why you can, for example, with a sprinter Correct the rear foot area without this Must have contact with the ground. It is possible with normal walking Lich to correct the forefoot as soon as the heel of the Schuhes has ground contact.

A design of the footbed is advantageous for sprinters in which, according to a further development of the invention Stiffening insert in the rearfoot area on the outside on Corrective tongue attacking the foot and raised to the side which has contact with the ground in the forefoot area tension from the outside against the rearfoot area is present. This allows you to use a pronating foot the rearfoot area immediately after the ground contact Correct the forefoot into a supination position  which diminishes when the foot sinks and again is lifted as soon as the rear foot area is in contact with the ground receives. In this way, the danger of an order reduce kinking inwards.

Over-correcting the back is particularly effective foot area possible before this area comes into contact with the ground Lich if the stiffening insert in the forefoot area one only on the inside of the foot to the front End-reaching support tongue and the correction tongue and support tongue around the normal foot shape The longitudinal axis of the footbed is twisted.

With some athletes, especially soccer players, a supination can be expected relatively often. Also in such cases is with the footbed according to the invention an early correction is possible if the stiffening insert in the rear foot area an inner egg Correction on the foot, laterally raised tongue which is in contact with the ground in the forefoot area with preload from the inside against the rear foot area applies.

Over-correcting the back is particularly effective foot area possible before this area comes into contact with the ground Lich if the stiffening insert in the forefoot area one only on the outside of the foot to the front End-reaching support tongue and the correction tongue and support tongue around the normal foot shape The longitudinal axis of the footbed is twisted.

The stiffening insert is very inexpensive to manufacture bar and has no comfort, ho hes weight when the stiffening insert from a Koh lefaser composite plastic.

The invention permits various embodiments. To further clarify its basic principle is one of which is shown in the drawing and is shown below described. They show in her

Fig. 1 is a plan view of an insole made as a formed insole according to the invention,

Fig. 2 shows a section through a front region of the foot bed along the line II-II in FIG. 1,

Fig. 3 shows a section through a central portion of the footbed along the line III-III in FIG. 1,

Fig. 4 shows a section through a rear portion of the foot bed along the line IV-IV in FIG. 1.

Fig. 1 shows an insole designed as a foot bed 1 for the right foot. In this footbed 1 is a hatched, flexurally elastic stiffening insert 2 made of a carbon fiber reinforced plastic. This stiffening insert 2 has a support tongue 3 in the forefoot region and a correction tongue 4 in the rearfoot region. While the support tongue 3 flat passes in the main extension plane of the footbed 1, the correcting tongue 4 leads up to a lateral edge region of the footbed 1 and is aligned with its upper edge approximately vertically. The entire stiffening insert 2 is twisted about a longitudinal axis 5 in such a way that when Bo the contact of the support tongue 3 presses the correction tongue 4 from the outside against the foot and thereby moves it into a supination position. Due to the elasticity of the stiffening insert 2 , however, the foot reaches its normal position as soon as it stands on the floor over its entire length.

Figs. 2, 3 and 4 illustrate the design of the reinforcing insert 2. In Fig. 2 you can see from it le diglich the support tongue 2 , in Fig. 3, a central area extending over the entire width of the footbed and in Fig. 4 only the correction tongue 4th
