Abstract

  The present invention relates to socks for use particularly during sports activities. A cushion is provided in the step region (1) of the sock. These cushions (2, 3, 4) are provided in the outer and inner sphere areas, the heel area and the outer area of the instep. An intermediate chamber (6) is formed between the cushions (2, 3, 4).

Description

  The present invention relates to a sock having a cushion provided in a stepping region, particularly for use during sports activities.

  In particular, during sports activities, human feet are generally housed in hard shoes. In this case, in particular, the foot is often surrounded by socks. Based on a lot of quick movements, there is an increased load on the foot during sports activities, which can lead to accelerated fatigue. Especially when the load distribution in the stepping region is uneven, this can lead to increased fatigue of the ligaments placed around the talar joint. This can lead to excessive fatigue or damage to the ligament, for example, during an incorrect stepping. In addition, instability of the tal tendon joint due to excessively fatigued ligaments can also result in damage to the knee and adjacent areas. Therefore, the anatomical load distribution in the stepping region is significant for the stability of the motor system, especially during sports activities.

  The stepping surface forms a three-point support between the heel and the outer and inner spheres (finger balls). This three point support allows the overall weight to be balanced by the legs. When walking, the natural vertical and horizontal circular caps of the foot act like a spring when stepped on. Load forces are absorbed in particular by the three-point support. In this case, about 40% of the load is on the outer and inner fingerballs and 33% is lost on the heel. About 15% of the load acts on the outside of the instep and the rest of the load is absorbed by the toes (about 5% for the inner toe area and about 7% for the outer toe area).

  In order to reduce the dynamic load of the foot and the premature fatigue caused by buffering the impact effects associated with such a load, especially in socks, soft cushioned toes, soles and heels It is known to provide an area (see German utility model 8701834). Further, the plantar region located between the heel region and the toe region may have a contour corresponding to the stepping surface (see European Patent Office No. 0845998). However, known socks do not consider the load characteristics specific to the tread surface.

  In this respect, the present invention is to be improved. The problem underlying the present invention is to provide a high wearing comfort, taking into account the characteristic load characteristics of the tread surface at the same time, especially in socks for sports activities. According to the present invention, this problem is solved by the fact that the cushion is provided in the outer and inner ball regions, the heel region, and the outer region of the instep, and an intermediate chamber is formed between the cushions. The

  According to the present invention, there is provided a sock taking into consideration a load characteristic peculiar to a foot, particularly in a sock for sports activities. Separate cushions in different load areas effectively support the foot and at the same time protect against overload. Furthermore, the spring action of the anatomical longitudinal and lateral caps is amplified by the cushion when stepped on, which also contributes to further removal of the talar tendon joints and ligaments. The partially formed cushion reduces the weight of the sock, especially compared to a sock that is continuously cushioned in the stepping area, which means that it is particularly endurance sports such as triathlon, Or in marathon running, it is a significant advantage. Furthermore, an intermediate air chamber provided between the cushions enables an increased air circulation.

  In a development of the invention, the cushions in the outer and inner sphere regions have different tissue structures. This allows the cushion area to be finely tuned to match the load distribution between the outer finger ball and the inner ball, thereby providing further improvements in protection and support functions.

  In the configuration of the present invention, a crescent-shaped sickle-shaped toe cushion is disposed in the toe region. Thereby, a significant proportion of the absorption is supported by the toes.

  Advantageously, the toe cushions are configured in the form of individual cushions, which preferably have different tissue structures. Thereby, non-uniform load distribution in the toe region is taken into consideration, and a peculiar load absorption becomes possible in this region.

  In another configuration of the invention, the sock has at least one side air conditioning passage that opens into at least one of the intermediate chambers of the stepping region formed by a plurality of separate cushions. is doing. Thereby, the continuous carrying-out of the sweat produced on the sole is promoted.

  Further developments and configurations of the invention are described in the remaining dependent claims. Embodiments of the invention will now be described in more detail with reference to the drawings.

  The sock selected as an example (FIG. 1) has a torso A and a foot B. Within the stepping area 1, the sock is partially provided with cushions 2, 3, 4 and 5. These cushions 2, 3, 4 and 5 are not coupled to each other, so that an intermediate chamber 6 is created between these cushions. The cushions 2, 3, 4 and 5 have an anatomical shape and are therefore optimally adjusted to the load characteristics of the foot.

  A circular heel cushion 2 is disposed in the heel region, and the heel cushion 2 is substantially equal to the shape of the heel as a stepping point. A substantially elliptical cushion 3 is provided in the area outside the instep, the longitudinal side of the cushion 3 being adjacent to the outside of the instep on the one hand and the longitudinal and lateral circular lids of the foot on the other side. Adjacent to the department. A fingerball cushion 4 is disposed in the fingerball region. Similarly, the cushion 4 has a substantially elliptical shape and extends from the outer finger ball to the inner finger ball. In the toe area, the foot 1 has a toe cushion 5 in the form of a crescent moon. In this case, the cushion shape is defined by different lengths and arrangements of the toes.

  In the embodiment according to FIG. 3, the sock has a fingerball cushion 4 consisting of two parts in the ball (fingerball) region of the stepping region 1. In this case, the cushion 41 directed to the inside of the instep has a higher density than the adjacent partial cushion 42. Contrary to the embodiment according to FIG. 1, the crescent-shaped sickle toe cushion 5 is configured in the form of five individual cushions 51, 52, 53, 54, 55, in this case each toe. One cushion is arranged correspondingly. These cushions 51 to 55 have various tissue structures. In this embodiment, the cushions 51 to 55 have a gradually decreasing density. In this case, the cushion 51 has the maximum density, and the cushion 55 has the minimum density.

  The cushions 2-5 have different thicknesses and densities, and may be made from one material or from different materials. Different thicknesses of the cushions 2-5 can be achieved, for example, by using thicker yarns or using more yarns. In particular, the cushions 2 to 5 may be configured with different hardnesses. Thereby, the cushion with a slight load, such as the toe cushion 5, may be configured to be softer than the cushion that receives a high load, such as the fingerball cushion 4. Of course, in the case of the embodiment according to FIG. 3, different hardnesses may be provided in relation to the load between the cushions 41 and 42 and between the cushions 51, 52, 53, 54 and 55.

  The cushion supports the inherently built fat cushion. A “barefoot environment” is provided to the foot based on special considerations of the load characteristics of the foot when forming and placing the comfort cushion. This “barefoot environment” is additionally caused by air circulation, which is caused by the intermediate chamber 6 formed between the cushions 2-5. Furthermore, moisture removal with an increased sole can be achieved by the air conditioning passage 7 extending to the side of the sock and opening into the intermediate chamber 6.

  As long as the description and claims refer to “socks”, the invention is not limited thereto. Rather, the concept of “socks” also includes stockings, tights and the like, and the present invention relates to these as well.

It is a side view of socks. It is a bottom view of socks. It is a bottom view of the sock by another structure.
