Description

The invention relates to a footwear sole the preamble of claim 1. The antiskid is works through spikes or runners attached to movable holders are arranged and depending on their position by a Mechanics are controlled from the tread of the sole protrude or are sunk in the sole; by means of simple Operation, the anti-skid can be adapted to the need.

Footwear soles with anti-skid devices are shown in fol known by gender:

• - Spikes arranged in the heel / shoe heel, which are allow to extend by means of a cam disk (DE 86 16 419 U1),  
• - arranged in the heel / shoe heel to a holder mounted spikes, which are operated by tool-operated let tooth-shaped elevations extend (DE-PS 2 32 062),
• - Spikes mounted on holders in the heel of the shoe, which can be extended using slot-shaped guides (US-PS 14 87 976),
• - spring spikes (DE 83 37 727 U1),
• - Spike holder adjustable via spacer plate (a Spike inserted in the longitudinal direction of the shoe sole holder that either by means of a spacer plate in the Position can be adjusted or with its top or The bottom can be inserted alternately (DE 84 08 334 U1),
• - Retrofitted additional devices, such as. B. Fold out crampons or shoe heels bare iron (see DE 86 26 424 U1; DE 29 37 755 A1).

The subject matter of the aforementioned publications  exhibit a space-consuming technology and construction and the following characteristics:

• - sometimes more cumbersome and high technical effort with anti-slip itself and actuation (e.g. DE 84 08 334 U1 and additional devices),
• - Partly limited anti-skid protection (e.g. spikes only in paragraph: DE-PS 2 32 062; U.S. Patent 1,487,976; DE 86 16 419 U1),
• - Sometimes no targeted control of the anti-skid device depending on the soil conditions (e.g. in the case of over freezing wetness in DE 83 37 727 U1).

The invention has for its object to provide footwear sole with integrated anti-skid device, which ensures safe anti-slip in every phase of use
which can be individually adjusted to the respective soil conditions by means of stepless regulation,
which can be operated easily, safely and comfortably and which is built flat and space-saving.

This task is done with a generic footwear sole according to the invention by the features of the mark partially solved the claim 1.  

The spikes and / or runners are on holders attached, which is essentially perpendicular move to the tread of the sole in guides can. The top of the spike sled holder are provided with inclined levels. Above the Spike skid holders are arranged which wedges can be moved in guides parallel to the outsole can. The bottom of these wedges (extend wedges) form inclined planes, fitting and fitting to the inclined planes on the top of the spikes skid holder. The Extending wedges can be mechanically e.g. B. Lever in position to the spikes Change skid holders. The one above the other pushing inclined planes of the spike skid holder and the extension wedges cause the position of the spikes Skid holder essentially perpendicular to the sole ongoing leadership and thus the needs-based Position of the runners and / or spikes to the tread the sole. Depending on the nature of the soil adjust the anti-skid as required (with ice / solid snow / thick layered smoothness → extended; in the case of over-frozen wetness / thin-layered smoothness →  partially extended; when sliding is not required Protection by runners / spikes → retracted. The retraction of the spike skid holder and the Securing the whereabouts in the partial or full retracted wedges, which in wedge-shaped recesses in the spike-holder intervention; they are in guided tours parallel to the Laufsoh arranged and mechanically rigid with the exits wedges connected. When pushing the Return wedges into the recesses in the holder because of the mechanically rigid connection the return wedges with the extension wedges the spikes Skid holder in the possibility of movement released at the top and from below by the Return wedges inserted into the sole and in the position held there.

Another advantageous embodiment of the counter status according to claim 1 results from claim 2. The rigid mechanical connection between the Extension and return wedges form one in the Footwear-guided strut that is longer or is wider than the tread of the sole. The protruding parts of the tread The strut can be mechanically affected (e.g. kicking against the curb) into the Insert shoe sole; this does one Change the position of the strut in the  Sole and thus the change in position the extension and return wedges and thus one Change of the spikes-skid holder to the outsole, whereby the level of anti-skid protection by spikes and / or runners is determined.

The position of the strut with extension and or Return wedges to the spike blade holders can can also be changed and discontinued that the strut over a lever Bowden cable in the required, desired Position is spent. The lever can be easily accessible position on the shoe or boot shaft to be appropriate.

The advantages that can be achieved with the invention are in particular:

• 1. Additional devices for anti-skid devices and their actuators are dispensable
• 2. enables the technology according to the invention
  • a) a flat, space-saving design adapted to the sole of the footwear,
  • b) the production of only a few components with a robust construction and simple process,
  • c) adaptable to the respective soil conditions, secured anti-slip and
  • d) safe, simple, manual operation of the anti-skid mechanism at all times.

The invention will now be described with reference to two Embodiments explained in more detail.

Fig. 1 shows a shoe sole with a footwear 1 with integrated Gleitschuhvorrichtung in heel and forefoot. It consists of holders 4 , in which the runners 3 and / or spikes 2 are let in and which have inclined planes 6 on their upper side and which are guided vertically to the sole 1 of the footwear. Above the holder 4 are extending wedges 7 arranged, which can be moved in parallel to the shoe sole 1 in guides 8 . The extending wedges 7 are provided with inclined planes matching the inclined planes 6 of the holder 4 . In wedge-shaped savings 9 in the holders 4 return wedges 10 are performed. A strut 11 connects rigidly the extending Rückholkeile 7 and 10 in sales and forefoot. The return wedges 10 are mounted in guides 16 . The strut 11 is positioned in guides 17 .

The horizontal movement of the strut 11 with molded wedges 7 and 10 can be brought about by means of the Bowden cable 13 and lever 14 .

Fig. 2 shows an example of an application for a non-manual, but to be actuated by foot movement of the overhang 12 on a fixed object A position of the anti-skid device. The holder 4 are arranged and adjustable as in Fig. 1, the strut (s) 11 are provided with protrusions 12 on the outsole 1 .
