Definitions

  • the safety head s S A consists of a body of resiliently deformable synthetic rubber-like material and is provided with a convex [56] References Cied front face covered with a smooth and even metal cap UNITED STATES PATENTS 5 Claims 8 Drawing Figures 3,284.09] l H1966 Spier 280M137 E X SAFETY HEAD FOR SKIS Modern skis have sharp tips at their front ends. Many injuries result from these sharp ski tips.
  • the main object of the invention consists in providing means for avoiding or at least reducing injuries resulting from a collision during down-hill movement.
  • a safety head for a ski tip comprising a body having a convex front face and a cavity which is open at the rear end of the body. at least the front face of the body being cov ered with a thinwalled outer cap made of a material having a higher specific gravity than that of the body.
  • FIGS. 1 and 2 show a plan view and a longitudinal section respectively of one embodiment of a safety head fastened to a ski;
  • FIGS. 3 and 4 show a plan view and a side view of a second embodiment of a safety head
  • FIGS. 5 and 6 show sectional views of the safety head taken along lines 5-5 and 6 6 of FIGS. 4 and 3 respectively;
  • FIGS. 7 and 8 show views of a reinforcing insert used in the embodiment of FIGS. 3 to 6, showing the insert in its original state and in its end state after bending into a U-shaped form.
  • a safety head 1 comprises a body 2 of synthetic material having a relatively low weight.
  • the front portion 3 of the body 2 has the shape of a hemisphere.
  • An upper rear flange 4 and a lower rear flange 5 are associ ated with the front portion 1.
  • the front portion 3 and the flanges 4, 5 form the integral body 2.
  • the outer surfaces of the flanges 4, 5 converge from the frontside to the backside. so that the height of the body is smallest at the rearward end.
  • the width ofthe flanges 4,5 increases in the rearward direction corresponding to the given shape of a ski front end or ski tip 6.
  • the body is closed at its sides rearwardly up to the point 7, where the two flanges 4,5 are associated with the body.
  • a flat cavity 8 is formed which is open at the rear side. This cavity is connected with a lateral slot 9 defined between the two flanges 4,5.
  • the cavity and the slot are of the same height.
  • Double sided adhesive strip portions 10 and II are fastened to the upper surfaces of the cavity 8 and the slot 9 and to the adjacent bottom surfaces of equal size respectively.
  • the two adhesive surfaces ofthe strip portions 10. 11 facing one another are covered with release paper strips.
  • the release paper strips are removed. then the two flanges 4, S are bent away from one another and the safety head is pushed onto the ski tip. whereafter the two flanges 4,5 are pressed against the ski surfaces for a short period. Because the shape of the cavity is adapted to the shape of the ski tip. after this operation the safety head is secured to the ski.
  • the body 2 ofthe safety head I is made of a yieldable material so that in the case ofa collision it can consume impact energy by deformation. If rubber-like material is used as the material for the body 2 two disadvantages would result because of the substantial friction at the surface of the body. If the body 2 strikes against the dressing of the body of a skier the deflection of the ski will be too small. The ski in a sort of way is held tightly at the collision point because of the frictional effect of the rubber body. The danger of injuries will be increased thereby. The great friction at the surface of the body would further result in a sticking effect between one of the skis and the rubber body of the other ski during down-hill movement. The danger of falling down is increased thereby.
  • a cap 13 made from a material having a higher specific gravity.
  • This cap 13 preferably is made of metal having a smooth and even outer surface.
  • the body is relieved at its outer sur face in the area where it is covered by the cap in order to form a recess into which the cap is inserted such that the outer surfaces of the cap and the adjacent portions of the body 2 are flush with one another.
  • the cap 13 is provided with rearwardly extending side flanges which end near the point 7 (FIG. I) in order to avoid contact between the longitudinal ski edges and the rubber-like body.
  • a further advantage resides in that the safety head has a large thrust surface. whereby the impact force per area unit and therefore the danger of serious injuries are reduced.
  • the hard and relatively inelastic cap 13 transfers the thrust pressure uniformly distributed onto the synthetic rubberlike body 2 whereby this body is uniformly deformed and a maximum of deformation energy is consumed.
  • the cap 13 is adhered to the front face of the body by a double-sided adhesive intermediate section 38.
  • FIGS. 3-6 show a second embodiment of a safety head which is fastened to the ski tip by a rivet, bolt or other pinlike anchoring element.
  • the synthetic body 22 provided with a metal cap 13 has an upper flange 24 and a lower flange 25, which contrary to the flanges 4,5 converge backwardly not only in their height but in their width.
  • the cap 13 also in this embodiment also has side flanges extending backwardly approximately to the rear edge 26 of the body side walls 27 but these side flanges are provided with a respective recess 28.
  • the recess 28 is situated in the area ofthe rear edge 26 of the body 22 and serves to facilitate the deformation of the synthetic body in this area. Because the synthetic material can flow out from the uncovered area of the body side wall 27 through the gap between the cap 13 and the side edge of the ski [not shown).
  • a plurality of longitudinal grooves 29 are provided extending in the front wall 30, upper wall 31 and bottom wall 32 of the body 22.
  • the longitudinal section shape of the groove is geometrically similar to the corresponding shape of the body 2 see dotted lines in FIG. 2). It is essential however that these grooves 29 starting from the cavity end at a distance from the outer surface of the body 22 and that ribs 33 are formed between each pair of grooves cooperating with the upper front and bottom surfaces of the ski tip (not shown). The grooves contact the ski surfaces and therefore the head is fixedly arranged at the ski.
  • a separate anchoring element as a rivet. bolt or screw.
  • This anchoring element could be inserted into aligned holes provided at the end of the body flanges 24, 25 and a corresponding hole in the ski.
  • the deformable material of the body 22 could be split off.
  • a thin-walled reinforcing insert 34 bent into a Lshaped form is embedded into the body 22.
  • the two legs 35, 36 of the insert 34 are connected with and preferably embedded in the body flanges 24, 25 respectively
  • a hole 37, or a pair of holes, is provided at the rear ends of the legs 35.36 respectively.
  • the holes of one flange and the holes of the other flange are aligned with one another and an anchoring bolt is inserted into the aligned holes of the flanges and the enclosed ski tip.
  • This bolt secures the reinforcing insert 34 to the ski which in turn secures the body to the ski owing to the embedding of the insert in the material ofthe body 22.
  • the reinforcing insert is adhered or vulcanized to the body 22.
  • the reinforcing element 34 is respectively shown before bending into the U-shaped condi tion and after this bending operation.
  • the reinforcing element 34 is provided with two narrow spaced bands. This construction helps not only to reduce weight as compared with a plate-shape reinforcing element, but
  • a safety head for a ski tip comprising a body hav ing a convex front face and a cavity which is open at the rear end of the body, said body including an upper flange and a lower flange, the two flanges being spaced from one another by an amount substantially equal to the thickness of the ski, and a thin-walled reinforcing insert secured to said body, said insert having a U shaped longitudinal cross-section with two rearwardly extending legs, each of which is connected to a respective one of said flanges, at least one hole being provided at the rear end of each leg such that at least two holes are aligned with one another and adapted to receive a connecting pin or bolt extending through the ski.
  • a safety head as claimed in claim 1, comprising a thin-walled metal cap covering the front face of said body, said body consisting of a resiliently deformable material.
