DE3818971A1 - Footwear sole with integrated, switch-in anti-skid protection device - Google Patents

Abstract

In order to obtain a footwear sole with an integrated, space-saving, anti-skid protection device which is simple to operate and can be adjusted to the respective protection requirement, spikes or skids are arranged on holders which are movable essentially perpendicularly to the sole and which, by mechanical means, can be controlled in their position and thus determine the projection of the spikes/skids from the walking surface. The upper side of the holders form oblique planes, opposite which lie extension wedges, guided at the same angle parallel to the walking surface. Wedge-shaped cutouts are made in the holders, in which restoring wedges engage, which are guided parallel to the outsole and connected rigidly to the extension wedges. For simple operation, extension and restoring wedges are connected to a strut which is guided continuously in the sole and which is longer or wider than the walking surface of the sole. The connected extension and restoring wedges can also be controlled with a lever, mounted on shoe or boot shaft, via a Bowden cable.

Description

I type of object of registration

The invention relates to a shoe sole with a Anti-skid device integrated into the sole and can be switched on or off. The anti-skid is effected through spikes or runners attached to movable holders are ordered 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 a The anti-skid device can be operated as required to adjust.

II State of the art

Footwear soles with anti-skid devices are in known in the following way

• - Spikes arranged in the heel / shoe heel, which can be extended using a cam disc (G 86 16 41 9.3)
• - spring spikes inserted into the sole (G 83 37 727.1)
• - Spike holder adjustable via spacer plate (one in Spike holder inserted in the longitudinal direction of the shoe sole, who either adjusts the position using a spacer plate become or alternate with its top or bottom can be introduced (G 84 08 334.4)
• - Retrofitted additional devices, such as. B. Rise iron or fold-out iron attached to the heel of the shoe (see G 86 26 424.9; P 29 37 755.7-26)

Critique of the state of the art

The inventions mentioned above have a space-consuming technology and construction and also have the following features:
sometimes cumbersome and high technical effort for anti-skid protection itself and actuation (e.g. G 84 08 334.4 and additional devices)

• - partially anti-slip protection (e.g. spikes only in paragraph G 86 16 419.3)
  sometimes no targeted control of the anti-skid device to the respective ground conditions (e.g. in freezing wet conditions with G 83 37 727.1).

IV task

The invention is based on the object: footwear sole with integrated, space-saving anti-slip protection direction, which the Bodenver conditions can be adjusted accordingly.

V solution

The object is achieved in that Spikes and / or runners, angled or curved arranged differently, movable and in the position tax bar as an integral part of the sole of the footwear are ordered.

The spikes and / or runners are attached to holders, which is essentially perpendicular to the tread of the Can move the sole in guides. The top of the Spike sled holders are provided with inclined levels. Wedges are arranged above the spike skid holder net, which moves in guides parallel to the outsole can be. The bottom of these wedges (extend wedges) form inclined planes that fit and fit to the inclined planes on top of the spikes Skid holder. The wedges can be extended using a me chanik, e.g. B. Lever in position to the spikes Change skid holders. The one above the other sliding inclined planes of the spike skid holder and the wedge extend the position of the spike 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 / firm snow / thick-layered smoother → extended; in the case of over-frozen wetness / thin-layered smoothness →  partially extended; when non-slip protection is not required by skids / spikes → retracted).

Retraction of the spike skid holder and securing of remaining in the partially or fully retracted Position return wedges, which are in wedge-shaped Engage recesses in the skid spike holder; they are arranged in guides parallel to the outsole and mechanically rigidly connected to the extension wedges. When the return wedges are pushed into each other stanchions of the holder are rigid because of the mechanically Connection of the return wedges with the extension wedges Spike sled holder in the possibility of movement after released at the top and from below by the return wedges inserted into the sole and in there Position held.

The rigid mechanical connection between the extension and return wedges forms a ge in the footwear sole led strut that is longer or wider than the barrel surface of the sole. The protruding over the tread Parts of the strut can be mechanically activated act (e.g. kicking against the curb) in the Insert shoe sole; this causes a ver Change in the position of the strut in the sole and thus the change in the position of the exit and return wedges and thus a change in the spike runners holder to the outsole, creating the level of anti-slip is determined by spikes and / or runners.

The position of the strut with extension and or return this can also wedge to the spike blade holders be changed and adjusted that the strut by means of a lever over a Bowden cable in the need-based te, desired position is spent. The lever can in an easily accessible position on the shoe or boot shaft attached.

VI Achievable Benefits

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

• 1. Additional devices for anti-skid devices and their operation  are dispensable.
• 2. The technology according to the invention enables
  • a.) a flat, space-saving design adapted to the sole of the footwear,
  • b.) the manufacturing process with only a few components with a robust construction and simple manufacturing process,
  • c.) a secure anti-slip protection that can be adapted to the respective soil conditions and
  • d.) Safe, simple, easy operation of the anti-skid mechanism at all times.
