DE2529027A1 - Spike grips for use in sports shoes - has faceted pyramids in curved surface and threaded shank for sole attachment - Google Patents

Abstract

The spike is for use on sports shoes of all kinds, and screwed into the sole of the sports shoe. The spike surface (1) which engages with the running track or ground is a small sector of a faceted sphere of radius (R), with a series of points or small spikes (1') cut on it. The small spikes are created by V form millings (6) and are pyramids (2) of different heights. The height variation (5) is very small, and is designed to comply with natural running movements and rolling on the soles. The attachment shank (3) is threaded (4) to secure it in a hole tapped in the shoe sole.

Description

Fitting part, especially spike for sports drawers of all kinds the @ main patent (patent application @ 22 34 098.3) and the. additional patents (patent application .L 22 54-152.2) are impact parts, especially soikes for everyone's sports shoes Kind, of various embodiments that are particularly well suited for use on Untstofflaufbehnen, the latter being largely spared.

The @rfanrung with these fittings has now ga shows that they, although they generally meet the demands placed on them, safety in operation of the runner increased and the protection of the @plastic running tracks as well can be improved.

@ So this additional invention has made it its business to create a spike to create that offers the runner even more safety and the plastic tracks nec is more gentle than that with the well-known forms of Kaupt and @. Additional registration is possible.

This object is achieved in that the effective step surface with the tip of the spike is a spherical radius, with the V-shaped millings Pyramids of different heights are formed.

The invention is in the drawing in greatly enlarged form shown and is described in more detail below. Figure 1 shows a . Seitenansicat and Figure 2 is a plan view of a spike.

The effective step surface 1 is an imaginary surface, formed by the spherical radius the actual effectiveness, i.e. H. the interaction of the However, spikes with the plastic track are only made with the tips 1 'of the pyramids 2.

These pointed 1 'are formed by the V-shaped vertical and horizontal sockets 6 and are located on the spherical adius R.

they differ in height 5 of the tips l 'is very small.

So if the highest point 1 'is only a fraction of a millimeter has penetrated into the plastic track, its neighboring tips are already touching 1 'the plastic sheet and take effect. The spherical arrangement of the tips 1 ', which are present on the fitting part or the spike, has a particular effect favorably on the natural movement of the foot, which is also radius-shaped runs, which is comparable to a rolling process that occurs with the appearance of the Heel begins and ends with the kick off by the toes. This natural and anatomical due to the spherical arrangement of the tips 1 'neither adversely affected by protrusions, corners or sharp edges and grants the runner an extremely high level of safety. Jer Spike is in a known manner Countersink with a pin 3, with whose winch 4 it is inserted into one in the outsole of one The threaded insert located in the sports shoe is screwed in, whereby e # of course is that an outsole is provided with several spikes.

The far increased safety for the runner and the greatest possible Protection of the plastic running tracks are the most impressive advantages of this invention Spikes.
