Abstract
A jig for drilling and/or tapping in a ski top the holes necessary for fixing a safety ski binding thereto comprises a frame adapted to be temporarily secured to the ski and consisting of a pair of parallel elastic rods along which a pair of slides are movable and adapted to be locked in the desired positions; each slide carries the necessary number of guide sockets for the bit and/or tap, the socket length and position on the frame being such that in combination with shoulder means provided on the bit and/or tap the depth of penetration of the bit or tap into the ski cannot exceed a predetermined value.
Claims11
Apparatus for drilling and tapping in a ski holes of predetermined depth for receiving therein screws necessary for fixing a safety ski binding to the ski, said apparatus comprising:
- a jig including an elastically deformable frame, releasable means on said frame for securing said jig to the ski during a drilling and tapping operation, and a plurality of guide sockets carried on said frame relatively spaced apart in accordance with the spacing of screw passage holes provided in the ski binding, each of said guide sockets including a top face, a bottom face, and an axial bore of predetermined diameter defined through said socket between said top and bottom faces thereof;
- and
- a bit and a tap, each including a body of substantially said predetermined diameter for guided entry into said guide socket bore during a drilling and tapping operation, a tip at one end of said body, and a shoulder spaced from said tip axially along said body and adapted to bear against the top face of said guide socket during a drilling and tapping operation, the spacing between the end of said tip and said shoulder of each said bit and tap being substantially equal to the sum of the axial length of said guide sockets and the predetermined depth of the holes to be drilled and tapped so that when said body of the bit or tap is fully inserted into the bore of one of said guide sockets whereby said shoulder abuts the socket top face, the eastic deformability of said frame enables the socket lower face to bear against the ski such that a hole thereby prepared in the ski is limited to the predetrmined depth.
Apparatus for tapping in a ski holes of predetermined depth for receiving therein screws necessary for fixing a safety ski binding to the ski, said apparatus comprising:
- a jig including an elastically deformable frame, releasable means on said frame for securing said jig to the ski during a tapping operation, and a plurality of guide sockets carried on said frame relatively spaced apart in accordance with the spacing of screw passage holes provided in the ski binding, each of said guide sockets including a top face, a bottom face, and an axial bore of predetermined diameter defined through said socket between said top and bottom faces thereof;
- and
- a tap including a body of substantially said predetermined diameter for guided entry into said guide socket bore during a tapping operation, a tip at one end of said body, and a shoulder spaced from said tip axially along said body and adapted to bear against the top face of said guide socket during a tapping operation, the spacing between the end of said tip and said shoulder of said tap being substantially equal to the sum of the axial length of said guide sockets and the predetermined depth of the holes to be tapped so that when said body of the tap is fully inserted into the bore of one of said guide sockets whereby said shoulder abuts the socket top face, the elastic deformability of said frame enables the socket lower face to bear against the ski such that a hole thereby tapped in the ski is limited to the predetermined depth.
Apparatus for drilling in a ski holes of predetermined depth for receiving therein screws necessary for fixing a safety ski binding to the ski, said apparatus comprising:
- a jig including an elastically deformable frame, releasable means on said frame for securing said jig to the ski during a drilling operation, and a plurality of guide sockets carried on said frame relatively spaced apart in accordance with the spacing of screw passage holes provided in the ski binding, each of said guide sockets including a top face, a bottom face, and an axial bore of predetermined diameter defined through said socket between said top and bottom faces thereof;
- and
- a bit including a body of substantially said predetermined diameter for guided entry into said guide socket bore during a drilling operation, a tip at one end of said body, and a shoulder spaced from said tip axially along said body and adapted to bear against the top face of said guide socket during a drilling operation, the spacing between the end of said tip and said shoulder of said bit being substantially equal to the sum of the axial length of said guide sockets and the predetermined depth of the holes to be drilled so that when said body of the bit is fully inserted into the bore of one of said guide sockets whereby said shoulder abuts the socket top face, the elastic deformability of said frame enables the socket lower face to bear against the ski such that a hole thereby drilled in the ski is limited to the predetermined depth.
