Definitions

  • the invention relates to wherein the 51 Im. c1 A43b 3/10 Spikes of nails disposed under the boot Sole are [58] Field of Search 36/25 R, 2.5 AJ, 7.6, ranged along two rectilinear rows One the inner 36/59 R, 62 64 side and the other on the outer side of the boot.
  • v 1 Claim, 5 Drawing Figures [56] References Cited PATENTEIJIAR 1 2 mm 3795; 993
  • FIGK F K13 A fR/AR ART 6 ICE CRAMPONS BACKGROUND OF THE INVENTION
  • the present invention relates in general to ice crampons, of the type currently used by ice climbers. Whatever their nature, arrangement, mounting and adjust- DESCRIPTION OF THE PRIOR ART
  • a typical prior art ice crampon arrangement as seen from beneath (FIG. 1) has spikes which are essentially curvilinear. Each dark spot designates the position of a spike; it is therefore clear that this spike arrangement is curvilinear on both left-hand and right-hand sides of the crampon.
  • the present-invention provides an ice crampon of which all the spikes disposed under the boot sole are arranged on two rectilinear rows, one on the inner side and the other on the outer side of the boot.
  • FIG. 1 shows the prior art as noted above:
  • FIG. 2 is a plan view from above showing the basic principle of the improved ice crampon according to this invention, this figure being comparable with FIG.
  • FIG. 3 is a diagrammatic side elevational view showing the position of a crampon on an ice slope
  • FIG. 4 is a diagrammatic perspective view showing the points of engagement and therefore of operation of a crampon according to this invention and according to the prior art on an ice slope, and
  • FIG. 5 is a plan view from above of a crampon according to this invention.
  • FIG. 1 concerning a conventional-type crampon
  • FIG. 2 designate the positions of the nails or spikes carried by the crampon.
  • These points and therefore the corresponding spikes are designated by the reference numeral 1, 2, 3, 4 and 5 as far as the inner side of the crampon is concerned. It is obvious, and this constitutes the primary object of this invention, that these points and therefore the spikes are disposed along a straight line denoted A-B for the inner side and C-D for the outer side of the crampon.
  • the crampon according to this invention bears with its five spikes 1, 2, 3, 4 and 5 since they are all aligned on a same straight line, as clearly apparent from FIG. 4.
  • the crampon according to this invention will bite much more efficiently the ice slope than the conventional crampon.
  • FIG. 5 illustrates an embodiment of a crampon according to this invention; however, it should not be construed from this specific construction that the invention is limited thereby, since many modifications and variations may be brought thereto without departing from the basic principle of the invention as set forth in the foregoing and in the appended claim. Thus, notably, the number of spikes and the general shape of the crampon may be modified without departing from the original features of this invention.
