  • ABSTRACT Primary Examiner1(enneth H. Betts Assistant ExaminerDavid M. Mitchell AttorneyRoger Goudreau [57] ABSTRACT
  • the invention relates to safety strap systems for skis and comprises:
  • a flexible locking thong is attached to one arm of the stirrup and is adapted to be hooked to the other arm of the stirrup; and means are provided to ensure that, when the thong is unhooked, the stirrup will move far enough backwards, and will spread its arms far enough apart, to allow the boot to move freely when the ski is being put on or taken off.
  • the present invention relates to a method of arranging a safety strap system for skis.
  • Known safety strap systems for skis secure the boots permanently to the skis; The purpose of these systems is to prevent total separation of the ski and the boot, after an event such as a fall has caused the safety binding, by which each boot is normally attached to the ski, to open.
  • Some known strap systems have only one point of attachment to the ski or the binding; in the event of a fall which causes the binding to open, the ski remains 'connected to the boot by only one strip of thong, and it may therefore fly round and injure the skier.
  • these safety straps usually made of leather orof a flexible synthetic material, has one disadvantage, namely that when the ski is not in use, the said straps lie at random on the ski; thus when the skier desires to put the skis on, he must put them in order before he can position his foot; he must then roll them appropriately around his boot, and finally fasten them. All of this is tiresome and is often difficult to do on a steep slope or in deep snow, especially with the heavy gloves that skiers usually wear.
  • the present invention proposes a simple and inexpensive solution of these problems; it relates to .a method of arranging a safety strap system in the form of a set of straps enveloping the boot and comprising two lateral attachment wings fastened to the ski,-the said process being characterized in that:
  • the straps which fit around the rear of the boot, and the lateral wings are made semi-rigid, in such a manner that, when the ski is not in use, this set of straps remains outside the area occupied by the boot;
  • the point at which the thong is attached to the set of semi-rigid straps is raised above the ski, thus shortening the length of the relatively flexible part, which will thus beslightly more than half the circumference of the boot at ankle level.
  • the safety strap system is provided with a tensioning device, more particularly a resilient element designed to clamp the boot
  • the said tensioning device will preferably be arranged on the hooking end of the thong, so that after the said thong has been unhooked it will naturally fall outside the area occupied by the boot.
  • the said tensioning device will be arranged on the inside face of the thong.
  • the semi-rigid straps mentioned above may be obtained, and may be kept in shape:
  • the invention also relates to a system of safety straps for the execution of the method described above, the said system consisting, according to the general aspect of the invention, of:
  • a locking thong attached by one end to a point on one of the arms of the stirrup near the forward end thereof, the other end of the said thong being hooked to a point near the forward end of the other arm of the stirrup, with the thong itself lying on the front of the boot;
  • the means used to urge the stirrup into the position of rest may be of any suitable type as long as they have sufficient elasticity to allow the stirrup to move forwards and the lateral wings to come together for the fastening thong to be passed across the front of the boot and hooked, furthermore to allow the stirrup to return automatically to the position of rest when the said thong is unhooked.
  • These means may consist, quite simply, of two upright wings attached to the ski in such a manner that they slope backwards and diverge from their point of attachment to the ski.
  • These two wings may be in the form of a strip of metal having a certain amount of resiliency and which has been suitably shaped for the purpose.
  • the .means for positioning the stirrup may be the arrangement of the upright wings in such a manner that they normally slope backwards, combined with a flexible connection between the central portion of the stirrup and a fixed point on the ski behind the upright wings.
  • the said means comprise a substantially vertical rigid rod fixed to the hinged jaw of the heelpiece and connected to the centre portion of the stirrup.
  • This rigid rod is integral with the jaw, so that when the latter opens, the said rod pivots backwards carrying with it the stirrup, which thus frees the space for the boot.
  • FIG. 1 is a schematic perspective of a first form of embodiment of a safety strap system according to the invention
  • FIG. 2 is a schematic side elevation illustrating the safety system in the open position or position of rest
  • FIG. 3 is a front elevation of the safety system in the position of rest
  • FIG. 4 shows the safety system according to the invention in the closed position
  • FIG. 5 is a perspective of a second form of embodiment of the safety system according to the invention, shown in the closed position;
  • FIG. 6 is a side elevation of a third form of embodiment of the invention, shown in the open position;
  • FIG. 7 is a section, to an enlarged scale, of a detail of a variant of a stirrup-fastening means
  • FIGS. 8 and 9 are variants respectively of the forms of embodiment illustrated in FIGS. 6 and 7.
  • numeral 1 indicates the part of the ski to which is attached heelpiece 2 of the binding used to connect the boot to the ski.
  • Numeral 3 indicates schematically the hinged jaw pivoting about an axis 4 and clamping the rear of the boot.
  • the safety strap system Located ahead of the said heelpiece is the safety strap system according to the invention, indicated in general by the reference numeral 5.
  • the safety system comprises two lateral fastening wings 6 and 7 arranged upright on the ski and attached thereto.
  • the said wings are made of a semi-rigid material having sufficient resiliency to return automatically to the position of rest shown in FIGS. 1, 2 and 3, after being deformed by stresses applied transversely or longitudinally of the ski.
  • these wings consist preferably of a flat strip of leather or suitable synthetic material, the middle portion of which is attached to the ski by means of a plate 8 screwed to the ski with screws 9.
  • This strip is curved to the shape of a U and is kept in this shape in the position of rest by means of a stirrup 10 consisting of two lengths of semi-rigid strap joined at 11, the ends of the arms of this stirrup being fastened respectively at 12 to the ends of wings 6 and 7.
  • a locking thong 14 is attached at 13 to wing 7 and carries at its free end an element such as a ring 15 intended to hook into a hooking means 16 of known type attached to wing 6.
  • the safety system is such that:
  • wings 6 and 7 diverge as a result of their natural resiliency which would cause them to lie flat in the plane of the ski, if stirrup 10 did not hold them up;
  • wings 6 and 7 slope backwards (as may be seen in FIG. 2); this slope is imparted at the time of assembly, either by deforming the material of which the wings are made, or by attaching the middle portion of the strip of which the wings are made to a slightly sloping surface provided on the ski.
  • the extent of the said slack may be adjusted by means of an appropriate metal buckle located at 11 on the stirrup, which makes it possible to adjust the length of the arms of stirrup 1'0.
  • the return of the safety strap system to the position of rest is due mainly to the resiliency and to the method of mounting wings 6 and 7. It would, however, be possible to provide a restoring means acting directly on stirrup 10.
  • the variants in FIGS. 5 and 6 show examples of this.
  • the stirrup consists of two strips 25 and 27 attached respectively to wings 7 and 6 by rivets 26 and 28; these two strips are joined at 29 by a ring which slides stiffly on the strands which, beyond the said ring, lie one on top of the other to form a common loop 30 attached at 31 to the back of the heelpiece or to the ski.
  • the resiliency of loop 30 tends to pull wings 6 and 7 backwards.
  • stirrup 25,27 may be adjusted by sliding ring 29.
  • lateral wings 32 and 34 are made from a flexible strip which bends under its own weight and has a tendency to place itself naturally upon the ski.
  • Wing 32 has a hook 33 and is connected by a rivet 36 to one end 37 of the stirrup, the other end 38 thereof being fastened at 39 to wing 34.
  • Wing 34 is extended by a thong 40 which carries at its end a ring designed to engage with hook 33, and a tensioning element 41.
  • stirrup 37-38 is attached, for
  • Rigid rod 43 may be attached directly to the jaw or, as a variant, it may be made as shown in FIG. 7, in which it consists of a rigid sheath 49 pierced by a channel 48 carrying a rope 45 which, in this case, is connected to the jaw in that it consists of two strands forming a loop surrounding a piece 46 located in a housing 47 in jaw 3.
  • Rigid sheath 49 is held between a stop and the upper surface of the jaw, thus keeping rope 45 rigid, the upper ends thereof being fastened to stirrup 37-38 as shown in FIG. 6.
  • Rigid rod 43 or part 49 are, of course, made of unbreakable material which should also be malleable, for instance like natural or synthetic rubber, so that they are not fragile and do not prevent the skis from being fastened together when they are put away; rod 43 or piece 49 will thus preferably be flexible enough to allow the unit to fold in all directions, especially towards the boot.
  • the slope of rope 45 may be ad- 1 justed in relation to the jaw by imparting to the base 50 of sheath 49 a slope in relation to its vertical axis.
  • part 49 a piece of non-malleable material.
  • part 49 will be hinged resiliently by its base to the jaw; this may be achieved merely by substituting for rope 45 a resilient element (such as a helicoidal spring or the like). Any displacement of part 49 will thus stretch the spring, and the latter will restore part 49 to its normal position after the load has been removed.
  • a resilient element such as a helicoidal spring or the like. Any displacement of part 49 will thus stretch the spring, and the latter will restore part 49 to its normal position after the load has been removed.
  • lateral wings 52-52 consist of a strip of flexible material kept in the shape of a U by a stirrup 53 made of relatively rigid material (metal or synthetic material).
  • the ends of wings 52-52 are attached to the ends of arms 54 of the stirrup by means of rivets 55, and the said stirrup extends rearwardly in the form of a similarly semi-rigid part 56 forming a loop and attached at 57, for example, to heelpiece 2 of the fastenings, more particularly to a manual boot-removal lever which allows the fastenings to be unlocked by pulling on loop 57.
  • One of arms 54 of the stirrup carries a thong 14 ending in a ring I5 intended to engage with hook 58 attached at 55 to the other arm 54 of the stirrup.
  • FIG. 9 The system illustrated in FIG. 9 is a variant of that in FIG. 6.
  • the majority of the elements of these systems are common to both, and are indicated by the same reference numerals.
  • rigid part 60 attached to jaw 3 of the heelpiece is of a different design to that in FIG. 6, being in the form of a T, to the cross arm of which stirrup 37-38 is attached by two rivets.
  • straps 37-38-32-34 are all flexible.
  • tensioning element 17 lining thong 14 as shown, it will be understood that this is not imperative, and that the tensioning element could be dispensed with as long as enough slack is left, when the thong is closed, to allow the boot to emerge from the safety fastenings, while the said slack is also short enough to prevent the boot, in the event of a fall, from being released even partly from the strap system, or from moving too far away from the ski.
  • the two wings 6 and 7 in FIGS. 1 to 4 instead of being made of leather or synthetic material, could be in'the form of a flexible metal strip folded to the shape of a U, with the middle portion thereof attached to the v ski.
  • the said U could be made up from several pieces.
  • a safety-strap system for surrounding a boot mounted on a ski comprising at least: two lateral fastening wings rigidly attached to the ski and having respectively an end spaced from'the ski; a stirrup open towards the front of the ski and fitting around the back of the boot, said stirrup having arms, and the end of which are respectively rigidly connected to the corresponding end of the wings attached to the ski; a locking thong attached at one end near one of the connections between said stirrup and said wings, the other end of the said thong being adapted to be hooked, after the thong has been placed around the front of the boot near the other connections between said stirrup and said wings; said set of straps including means for urging said stirrup and said lateral wings ina position of rest slightly outside the area to be occupied by the boot, when the thong is unhooked, the stirrup moving back far enough, and its arms open wide enough to allow the boot to be removed from the ski unimpeded, or to be replaced unimpeded, when the ski
