Description

roller skates

technical field

The invention relates to a shoe having a shaft and a load-relieving shaft recess.

Background technique

To allow a shoe to be attached to a frame (such as an inline skate or ice skate), or any shoe with a hard sole (such as a cycling shoe) without sacrificing an at least partially curved shaft to improve wearing comfort, and Without altering the shape stability of the shoe necessary for the transmission of forces, it is known to provide shaft recesses on the frame (for example connected to a rigid sole) which, when given shape, act on the shaft The support, however, is not stiff enough by itself, especially at the ankle, so the strain that occurs on the shaft recess can be removed on the frame (eg on the sole). A disadvantage, however, is that the shell-shaped shaft recess, which exhibits sufficient shape stability for this purpose, can only cover average foot shapes and cannot subsequently be adapted to any possible user's different foot shapes.

Contents of the invention

In this way, the present invention is based on the object of creating a shoe according to the prior art initially described, such that it is then possible to adequately adapt to the different foot formations of users without accepting the loss of interchange at the expense of a good support for the foot.

The invention solves the posed problem by providing a shaft recess comprising at least one load-relieving outer part and at least one partition supporting part of the shaft on the outer part.

Based on this measure, the arrangement of the shaft including the toe cap and the counter, ie the upper of the shoe, can be compared to the The shaft recesses are altered in selected areas and thus can subsequently be fitted to the shape of the user's foot when the outer part of said shaft recesses needs suitable strength and shape stability for support in order to dissipate loads, thereby in turn obtaining a perfect fit in the shoe. Formally stable support of the shaft in the shaft recess. In this context, it is to be noted that in many cases it is necessary or desirable to obtain a non-rigid support of the shaft in order to avoid overloading of the foot, for example in locally restricted sections. For this reason, the supporting outer part of the shaft recess can be at least partially elastically supported, with a corresponding spring constant, or acted upon by the intervention of elastic and flexible partitions, so that the supporting force can be limited by a preset spring force.

Although it is possible to achieve good adjustment of the arrangement of the shaft by using interchangeable partitions, easier operating conditions can be obtained when the partition acting between the shaft and the outer part is adjustable, and thus by adjusting The divider provides adjustment for various tissue disabilities.

In order to avoid localized load overloading of the foot in the area of the spacer, the shaft may comprise reinforcements in the area of the spacer which provide a corresponding distribution of pressure over the contact area of each spacer. However, special care is required at the shaft itself due to the reinforcements. In order to avoid reinforcement of the shaft, the shaft recess adjacent to the outer part may comprise an inner part mounted along the shaft and at least one divider between the outer part and the inner part, thus performing over the inner part The pressure distribution is perfect, and the adjacent shaft does not require reinforcements. In order to be able to carry out the adjustment of the adjacent areas of the shaft support over the inner part of the shaft recess, largely independently of each other, the inner part can be assembled from separate parts separated from each other. Advantageous construction conditions are obtained if the inner part of the shaft recess forms a shell which at least partially surrounds the shaft with self-adjusting flaps which are separated from each other by gaps at the edges, because in In this case, no separate mounting of the individual parts of the inner part is required.

The outer part of the shaft recess follows the shaft at a distance which fits to the average foot shape, thus gaining an adjustment aid, since only differences in the average foot shape are taken into account from the intermediate distance between the outer part and the upper, This generally requires a shorter travel distance of the separator. In addition, more optically appealing shoe shapes can be arranged more easily.

As mentioned above, if a corresponding distribution of the outer portion over the shaft surface is provided, there may be an influence on the shaft arrangement, and this is achieved by the removal of the shaft and the shaft recesses in a suitably curved, at least in the adjustment area. The spacer between the outer part of the load (and thus over the entire area of the shaft) has an effect on the shape of each foot. This means that, according to the measure according to the invention, not only the ankle area is adjusted, but also the arch, instep and/or heel area is adjusted. Even the arch area or the width area of the shoe can be adjusted when only the outer part of the shaft recess is used to create a suitable support for the partition. For this purpose, preferably, the outer part of the shaft recess forms a cage which partially surrounds the shaft. In order to easily achieve the processing conditions for adjusting the divider, each of the above-mentioned dividers may be formed as an adjustment screw mounted in the outer part of the shaft recess and adjustable by turning. Adjustment is performed by turning the adjusting screw, and then the distance between the outer portion of the shaft recess and the shaft can be adjusted smoothly, whereby the adjusted distance does not need to be secured due to the self-locking thread engagement.

Detailed ways

The roller shoe according to the illustrated embodiment comprises a chassis 1 carrying inline rollers. On the chassis 1 a shaft recess 3 for a shaft 4 of a shoe 5 is provided. This shaft recess 3 consists of a rigid outer part 6 connected to the chassis 1 together with an inner part 7 which is inserted into the outer part 6 and, according to the embodiment shown, forms a housing, relative to the shaft 4 nestled together, which for example form flaps 9 in the ankle and heel regions, which are separated from each other by gaps 8 at the edges. These flaps 9 are located on the shaft 4 at a distance from the outer part 6 . In this area, the outer part 6 is arranged along the arc by a partition 10 in the form of an adjusting screw 11 , which can be adjusted by turning and inserted into the outer part 6 and acts on the flaps 9 of the inner part , as shown in Figure 2 in particular.

By being mounted in the outer part 6 and with the aid of turning an adjustable adjusting screw 11, the distance of each fin 9 of the outer part is independently adjustable, so that the inner part 7 obtains a different arrangement from that of the outer part 6, whereby Taking into account the physiological differences between the user's foot shape and the average foot shape is taken into account by eg the presetting of the outer part 6 . The screwing depth of the adjusting screw 11 thus determines the shape of the shaft in the region of the wings 9 , whereby an advantageous adaptation of the shaft recess 3 to the individual foot shape is achieved. Usually, adjustments in the ankle area will be sufficient. However, this does not mean that such adaptations are excluded in other areas of the shaft 4 .

The invention is of course not limited to the embodiments shown and can be applied to any embodiment covered by the independent claims. As such, the present invention does not require any roller skates or any other shoes that have a frame for connecting shaft recesses. In fact, the shaft well can be very perfectly connected to the bottom of the shoe, whereby said bottom is not even generally rigidly formed, so that on the outer part of the shaft well, which is attached to the bottom, there can be a counteraction to the shoe. Proper support for dividers on the system.
