Definitions

  • the device includes: a mounting connected to the base and located externally of the space covered by the boot during the operations of putting-on and taking-off the ski; an element for retaining the boot located at least partially within the space covered by the boot and pivoting, between the positions in which it locks and releases the boot, about a horizontal axis located in the mounting and running transversely thereto; and a resilient system allowing the device to move between a position in which the boot is locked and a position in which the boot is released.
  • This system is characterized by resilient means supported by the base and urging the mounting into a position which is raised in relation to the base and in which the boot is released, and by another resilient means acting between the mounting and the retaining element and urging the retaining element into a position in which the boot is released.

  • the present invention relates to a device for securing a boot to a base.
  • the base may consist more particularly of a sports article, such as a boot stretcher, a ski, ice skates or crampons, an intermediate plate to be fitted under the boot, or any other possible type of base.
  • the first group is that of heel-pieces consisting of an element secured to the ski behind the location to be occupied by the boot; they comprise a jaw hinged to the element and connected to a resilient locking system.
  • the jaw is adapted to assume two positions: an open position in which it leaves free the space to be occupied by the heel of the boot; and a locked position in which it is closed on to the boot.
  • the jaw is frequently associated with a pedal supporting the heel of the boot, which makes it possible to put the ski on automatically (without using the hands). This is known as a step-in binding. This kind of binding involves a rather complex and voluminous, and therefore heavy, mechanism having a large number of parts requiring relative accurate assembly;
  • the second group covers those bindings known as pivoting bindings.
  • These bindings are in the form of a stirrup and usually comprise a resilient locking system, the stirrup being adapted to enclose the rear of the boot.
  • the arms of the stirrup are attached to the ski in an area below the boot.
  • the ends of the stirrup arms are usually hinged to a plate rotating about a pivot on the ski, in order not to interfere with the lateral release of the boot.
  • the arm hinges rotate freely, so that when the binding is in the inoperative position it generally rests upon the ski outside the area to be occupied by the boot.
  • This type of binding may also have a pedal for putting the ski on.
  • pivot bindings may be simpler in design, lighter, and less costly than heel pieces, they have the disadvantage of requiring the use of the hands in order to put the skis on, even if they are step-ins.
  • the invention relates to a very simple form of binding which consists of only two parts and which makes it possible to put the ski on automatically without using the hands.
  • the structure of the present invention provides automatic adaptation to boots of slightly different lengths (one or two sizes, for example) and/or having soles of different thicknesses, although in the case of large variations in the length of the boot, a conventional length adjustment is, of course, indispensable; it will be understood that this automatic adaptation is mainly of interest where foreign bodies such as mud, snow, graveL'etc.
  • the binding according to the present invention comprises at least one soleretaining element hinged to a mounting attached to the base; a similar arrangement may be found, for example, in French Patents 1,110,856, 1,190,118, 1,549,275, 2,034,708, and in Swedish Patent No. 110,142.
  • the binding according to the present invention comprises resilient means urging, on the one hand the mounting and, on the other hand, the retaining element into a specific position, namely the position securing the boot. With the system according to the invention, the binding cannot be locked unless the boot is in place on the ski. With no boot on the ski, even if the user inadvertently actuates one of the parts of the device, the latter always returns automatically to the open position ready for the ski to be put on.
  • the invention is therefore concerned with a device for securing a boot to a base, particularly a base which is a part of a sports article and which is equipped with means for holding one of the ends of the boot, the device being characterized in that the resilient means acting between the base and the mounting is integral with the mounting itself, the mounting being made of a semirigid, flexible material, of which the part adjacent the base is fixed in relation thereto.
  • the retaining element comprises at least one jaw which is urged, when the device is inoperative, into a raised position in relation to the mounting by an out-ofbalance effect transmitted by a counterweight or a spring; the jaw is free to move between at least two positions determined in relation to the hinging of the retaining element to the mounting, namely an upper position corresponding to the position in which the device is at rest or ready for putting the ski on, and in which the jaw is free to move about its hinge, and a lower position corresponding to the position in which the boot is applied to the base and the jaw is locked against the boot, at which time the retaining element may be locked by the resilient means acting upon the mounting.
  • the resilient means associated with the mounting may be the mounting itself, if the mounting is made of a semi-rigid, flexible material (such as a flexible steel rod); in this case, the lower part of the mounting will be embedded in the base so that it cannot rotate.
  • the lower part of the mounting may be arranged to rotate freely on the base, in which case the resilient element may be a spring located between the base and the mounting or between the base and the retaining element.
  • the retaining element may comprise, in addition to the jaw, a pedal for putting on the ski, but such a pedal is needed only if the sole of the boot is more than about 1 cm in thickness.
  • the boot could be provided with a stationary projection which could act as a pedal, in which case the jaw would be resiliently mobile between the arms of the mounting connected to the base.
  • the device according to the invention may be mounted on a plate rotating about a stationary pivot on the base (as in pivoting bindings), but this is not mandatory.
  • any impairment of the lateral release of the boot may be prevented by arranging a space between the mounting of the device and the boot. Moreover, the resiliency of the mounting will lend itself to the displacement of the boot.
  • the device according to the invention also provides an elegant, simple, and effective solution of the problems raised by the bindings known as plate bindings.
  • the sole of the boot is made temporarily integral with an intermediate plate, the end of which co-operate with retaining elements (the stop and the heel piece), the safety release occurring between the plate and the ski.
  • the binding may then be provided with an automatic return of the plate on the ski, or step-in.
  • the boot is attached to the plate by a somewhat simple attachment system which does not provide for automatic fitting of the ski or step-in.
  • the device according to the invention provides a still simpler and more economical solution in the special case of plate bindings.
  • a known system of safety binding consisting of a jaw serving as a stop for one end of the plate and a resilient locking block arranged on the ski in the vicinity of the other end of the plate and arranged to co-operate with a release ramp mounted on the plate, the ramp permitting both lateral and vertical safety release; and a device according to the invention is installed on the plate, the device being connected to the ramp which is mounted movably on the plate.
  • the resilient locking block co-operating with the ramp which not only makes this a step-in" device for the boot on the plate, but also automatically returns the plate-boot unit to the ski. This is possible because the characteristics required on the resilient block are very much the same in both cases.

  • a ski l is provided with a front stop 2 intended to accommodate the front of the sole 3 of a ski boot 4.
  • the back of the sole co-operates with a binding device indicated generally by the numeral 5.
  • This device consists of a mounting in the form of a stirrup having two lateral arms integral with a plate 7 comprising a depression 7 in which the tip of a ski-pole may be placed in order to release the device intentionally.
  • Arms 6, themselves constituting a resilient means, are made of a semi-rigid and flexible material such as spring steel and are attached by their lower ends to a cross-piece 8 sliding in a slot 9 machined into the thickness of the ski.
  • the cross-piece may nevertheless be locked in relation to the ski by means of screws 10 engaging in a series of tapped holes 11 in the ski. This arrangement makes it possible to adjust the position of device 5 in relation to the ski as a function of the size of boot 4.
  • arms 6 of the mounting are attached to cross-piece 8 in a manner such that they rise above the ski at an angle of 01 when the device is inoperative. It will also be observed that cross-piece 8 is very definitely below the sole of the boot.
  • Running between arms 6 is a horizontal member 12 on which a retaining element 13 is arranged to rotate freely, the element assuming, in its inoperative position, by reason of its own weight, the position shown in FIG. 1; this merely requires that centre of gravity 5 of the retaining element be offset in relation to member 12, a resilient restoring force, produced by the weight, thus acting upon the retaining element by reason of the lever arm between member 12 and point G to which the tip of the retaining element is applied.
  • the retaining element has a jaw consisting of a pair of ears 14 in which is mounted a shaft 15 carrying a roller 16 which rotates freely thereon. It also comprises a projecting portion 17 running approximately in the same direction as jaw 14-16.
  • the mounting is thus under tension, i.e. angle a that it forms with the ski is larger than angle a, but smaller than angle a the angle in the position of rest. It will be understood that the device as shown in full lines in FIG. 2 will resist any attempt to lift the heel of the boot, although it may be unlocked at will by pressing plate 7 of the mounting with the tip of a ski-pole.
  • the mounting consists of circular-section spring-steel arms also integral with a lower cross-piece 8.
  • Retaining element 20 rotates freely on shaft 12 in mounting 19 and is provided with two pairs of ears 21 and 23, one of them accommodating a roller 16 rotating freely on shaft 15 and acting as a jaw, while the .other carries a second roller 24 serving as a pedal and rotating freely on shaft 25.
  • element 20 is equipped with an adjusting screw 26, the rounded end of which comes into contact with the boot when the device is locked (as shown in full lines in FIG. 6). It will be understood that the slope of the retaining element in relation to arms 19 may be adjusted by making the shank of the screw project to a greater or lesser degree from the retaining element.
  • FIGS. 5 to 7 illustrate another example of embodiment of the device, in which the mounting, instead of being secured to the cross-piece, pivots thereon.
  • cross-piece 27 has two lateral extensions 28 carrying eyes 30 at the ends of arms 29 of the mounting.
  • the arms may be completely rigid.
  • Arms 29 have bearings 31 carrying a freely rotating shaft 32 integral with a retaining element 20, identical with that in FIG. 4, which is urged into the inoperative position shown in FIG. 5 by springs 33 surrounding shaft 32, one end of each of the springs resting against the retaining element at 35, while the other end rests against arms 29 at 34 (FIG. 7). It will be observed that the rotation of the retaining element is restricted bymeans of stops 36 thereon which rest, in the position shown in FIG. 5, against stop extensions 37 integral with mounting 29.
  • the mounting is maintained in the erected inoperative position by lateral springs 40 located between one of arms 29 of the mounting and a sloping bracket 39 running from an extension 38 of cross-piece 27.
  • the ends of each of springs 40 are preferably, but not necessarily, secured to arms 29 and bracket 39 as shown, forward pivoting of the mounting being thus restricted.
  • the device of the examples of embodiment so far illustrated and described is not provided with a safety release since, as may be seen in FIGS. 2 and 6, the roller of the jaw passes over dead-centre X-X. There is no problem, however, in providing a safety release, especially in the device illustrated in FIGS. 4 to 7. As already stated, it is merely necessary to adjust screw 26 to prevent the roller from passing over the dead-centre. This configuration of the device is shown in FIG. 8.
  • the variant of the device shown in FIGS. 9 and 10 makes it possible to adapt the device, without impairing its function, to a wide range of sole thicknesses or to the case where a foreign body (mud, snow) becomes lodged under the sole of the boot when the ski is being put on.
  • either the jaw alone (as illustrated), or the whole retaining element, is mounted resiliently in relation to the arms of the mounting.
  • Spring-steel arms 41 of the mounting are secured to a cross-piece 42 accommodated in ski l and they carry, in bearings 43, axes 44 on which retaining element 45 rotates freely.
  • the latter comprises a fork 46 carrying a pedal-roller 47 on an axis 48.
  • a part 49 carrying an adjusting screw 50 slides on threaded rods 51 engaging in the body of retaining element 45.
  • Nuts 52 on threaded rods 51 limit the distance between part 49 and the retaining element.
  • the body of element 45 has a cavity 53 in which there slides a fork 54 emerging to the outside through an opening 55.
  • Fork 54 carries a jaw-roller 56 rotating freely on a shaft.
  • Located between part 49 and fork 54 are two springs 57 urging the said fork outwardly.
  • roller 56 may move resiliently, as a function of sole thickness, against the action of springs 57.
  • the mounting consists of two rigid arms 110 pivoting freely at 111 on adjustable cross-piece 1 12 accommodated in a recess 9 in the ski and secured by screws 10.
  • the free ends of arms 110 are connected by a shaft 113 on which a retaining element 114 rotates freely, the general configuration of the element being similar to that of element in FIGS. 9 and 10, i.e. ajaw-roller 117 rotates freely on the axis of a fork 54 adapted to slide. against the action of springs 116, in body 114 of the element.
  • the body carries at least one stop 118 which comes into contact with arms in order to restrict the rotation of element 114 in the inoperative position shown in FIG. 11.
  • Element 114 also has cheeks 119 carrying a shaft 120 on which there rotates freely a roller 121 which turns in a bore in head 122 of a tele scopic assembly indicated in a general way at 123, the head 122 being preferably rounded-off and serving as a pedal for sole 3 of the boot.
  • Base 124 of the telescopic assembly pivots freely on axis 125. The relative motion between head 122 and base 124 of the telescopic assembly takes place against or under the action of a spring 126.
  • ski-removal lever 114 comes up against the boot when the mechanism is in the locked position.
  • FIG. 13 is a schematic representation of another example of embodiment.
  • the full lines show the device in the locked position, while the dotted lines indicate the inoperative position.
  • a cross-piece 128, adjustable in accordance with the length of the ski carries lateral arms 129 of a mounting rotating freely on axes 130 and equipped with an axis 131 on which retaining element 132 rotates freely, the element being provided with a jaw-roller 134 free to rotate about axis 133.
  • the latter extends laterally, carrying at each end the head 135 of a telescopic resilient element 136 comprising a spring 137, foot 138 of the element rotating freely on an axis 139 of cross-piece 128.
  • Telescopic element 136 urges roller 134 towards the position shown in dotted lines (in which the device is inoperative) where it is halted by a stop 140 on mounting 129, which prevents it from pivoting further.
  • a stop 141 on mounting 129 prevents the retaining element from going beyond its operative position, shown in full lines.
  • this stopping of the retaining element in its operative position could be obtained by causing the said retaining element 132 to rest against the boot, as indicated in the foregoing examplesv
  • the solution indicated in FIG. 13 is preferred, since it facilitates removal of the ski, which may be make automatic by displacing mounting 129 and therefore stop 141. This movement is accomplished by pressing ski-removal lever 142 which is an extension of mounting 129.
  • the pedal for automatically putting the ski on may, with advantage, be located on the boot, as shown at 143, the pedal being either a projection from the boot or a part fitted thereto.
  • a base 144 is secured adjustably to ski 1 by screws 10, the base comprising two uprights 145, between which is located a retaining element 146.
  • the latter rotates freely about an axis 147 integral with a U- shaped stirrup 148. the ends of axis 147 sliding in curved slots 149,150 machined in uprights of the fixed base.
  • These slots 145,150 allow stirrup 148 to move, the centre of the arcs being located at a point 151 below the sole of the boot; it will be understood that strirrup 148, and therefore the retaining element, thus move along the arc ofa circle, the centre of which is point 151.
  • the retaining element is urged into the inoperative position shown in FIG. 14 by means of a spring 152 located between base 144 and the transverse arm of stirrup 148.
  • the spring is threaded over a rod 153 which follows the arc of a circle centered at point 151, the lower end of the rod being integral with base 144.
  • the free end of rod 153 is accommodated, with a certain amount of play, in a hole 154 in the transverse arm of stirrup 148.
  • jaw 155 and pedal 156 of the retaining element are both in the form of rounded projections on the retaining element. Although this is a workable arrangement, it is not as efficient as rollers. Element 146 may, of course, be provided with rollers, as in the preceding examples.
  • This type of device operates in a manner similar to that described more particularly in connection with FIGS. 1 to 5.
  • the binding is mounted in known fashion on a plate 157 which turns about a central pivot 158 secured to ski 1.
  • the binding comprises, in known fashion, a generally V-shaped element 159. Hinged on an axis 160 between the arms of the V is a retaining element 161 which is similar to element 13 in FIG. 1, for example, and is adapted to co-operate with the sole of the boot.
  • Semi-rigid rods 162,163 run partly within the arms of the V, springs 164,165 being threaded over the rods. One end of each spring rests against an adjustable stop 166 on the rod, while the other end rests against a projection 167 from the arm of the V.
  • One of the said rods (163, for example) may be released from its housing through slots 168,169 located in the ends of one of the arms. Since this is a conventional design, it will not be described in detail.
  • the free ends of semi-rigid rods 162,163 terminate in hooks 170,171 co-operating with arches 172,173 integral with plate 157. This hook-arch attachment allows the device to rotate in all directions, which is indispensable if the binding is to release correctly.
  • FIG. 17 1 indicates a ski comprising a front stop 60 and a resilient rear locking block 61 of conventional design.
  • the locking block may contain a piston 62 acted upon by a spring 63 accommodated in the body of the block, the force exerted by the said spring being adjusted by means of a threaded plug 64.
  • An intermediate plate 65 designed to be attached to boot 4, is engaged at its front end with stop 60 and cooperating at its rear end with piston 62 through a part 65 integral with the plate and comprising a ramp 69 of V-shaped cross-section. Since this type of device is known, it will not be described in detail. It will be sufficient to mention that it allows the plate, with the boot, to be released both vertically and in the plane of the ski.
  • part 66 is mounted on the plate in a manner such that it can slide longitudinally. To this end it has a base 68 which may be dovetailed, for example, and which engages in a corresponding guide housing 67 machined into the plate. Forward travel of part 66 is limited by stop 70.
  • the plate itself has a front stop 71 which holds the front of the boot; at the rear it has a device indicated generally by the numeral 72, the general structure of which resembles that of the device in FIGS. to 8.
  • Rigid mounting 73 of the device rotates freely, at 74, on cross-piece 75 accommodated adjustably in slot 76 in the plate, and a retaining element 73, identical with that in FIGS. 5 to 8, rotates about an axis 77.
  • each arm of the mounting is connected to part 66 by a link 79 hinged freely at 80 and 81 to the mounting and to part 66.
  • plate 65 is normally locked to the ski at all times.
  • plate 82 still accommodates a cross-piece 83 equipped with lateral axes 85, but arms 84, which rotate freely on axes 85, are integral at their rear end with a plate 86 approximately perpendicular to arms 84 and provided with a ramp 87 designed to cooperate with piston 62 in the locking block. Furthermore, the front face of plate 86 is equipped with a fork 88 carrying an axis 89 on which a retaining element 90, simlar to that in FIG. 4, rotates freely.
  • the adjustment screw of the retaining element is adjusted to ensure that the jaw-roller passes over the dead-centre point X-X in the position in which it locks the boot to the plate.
  • the plate and the boot are safety-released, they remain attached to each other by the device.
  • the plate may be conveniently released at will by applying pressure to the top of plate 86 (against the action of spring 63 if the plate is still attached to the ski).
  • FIGS. 21 and 22 illustrate a system similar to that in FIGS. 19 and 20, except that a lever for removing the ski at will is hinged to the top of plate 86.
  • This lever may be in the form of a fork and may comprise, as an extension of arms 92 hinged at 91 to plate 86, a small plate having a depression 93 for the tip of the ski-pole.
  • the lever is urged into the position shown in FIG. 21 by springs 95, each spring being hinged by one end at 96 to an extension 94 of arm 92 and, by the other end, at 97 to an arm of fork 88 of the plate.
  • the lever also serves as a stop for the retaining element when the latter is in the locking position shown in FIG. 16.
  • This is achieved by the provision of projections 88 arranged on the lever and extending into the path of the retaining element, the projections exhibiting a flat front face for the support of the retaining element (FIG. 22) and an inclined ramp 99 which allows lever 92 to move against the action of spring when the retaining element pivots from its inoperative position into its locking position for the purpose of holding the boot (arrow F).
  • a stop 100 may also be provided on plate 86, to restrict the pivoting of the lever in the direction of arrow P.
  • lever 92 When it is desired to remove the ski, pressure is applied to lever 92 at depression 93, causing the lever to pivot until it comes up against stop 100 and, at the same time, releasing the retaining element by moving stop 98 out of the way. Continued pressure on the lever lowers plate 88 which pushes piston 62 back and makes it possible to remove the ski. It will be observed that stop 98 on lever 92 prevents the retaining element from pivoting in a direction opposite to that of arrow F; with an arrangement of this kind, it is therefore no longer necessary that the jaw-roller of the retaining element shall pass beyond the dead-centre point, in order to make the binding irreversible, i.e. unreleasable.

  • a device characterized in that the retaining element comprises, in addition to the jaw, a pedal running substantially in the same direction as saidjaw, but offset therefrom in relation to the hinge axis of the retaining element on the mounting.
  • a device characterized in that the retaining element comprises, at the end remote from the jaw and pedal and on the other side of the hinge, an adjusting screw adapted to bear against the boot when the device is in the position in which it holds the boot to the base, said screw making it possible to adjust the angle of the retaining element in relation to the mounting.
  • a device characterized in that at least that part of the retaining element which is adapted to ensure retention of the boot is mounted in a manner such that it can move resiliently in relation to the mounting, a resilient element being provided between said pair of the retaining element and the assembly which is fixed in relation to the mounting.
  • a device characterized in that the retaining element as a whole is held resiliently in relation to the mounting.
  • a device characterized in that the jaw consists of an independent part freely accommodated in the retaining-element block and urged, by means of springs, towards the exterior of the retaining element.
  • a device adapted to unite the boot with an intermediate plate held to the base by means of a safety-binding system which releases the plate and the boot in the event of excessive stress, said system consisting of a jaw acting as a stop for one end of the plate and, in the vicinity of the other end of the plate, of a resilient locking block co-operating with a ramp attached to the plate and providing for lateral and vertical safety release, characterized in that said device is connected to said ramp which is mounted so that it can move on the plate, the resilient locking block cooperating with the ramp ensuring the retention of the device in its raised inoperative position.
  • a device comprising a mounting associated with a retaining element and hinged to the plate, below the sole of the boot, by a freely rotating axis, characterized in that said mounting is connected, by means of a linkage with freely rotating hinges, to the ramp which is mounted on the plate so that it slides freely in the longitudinal direction in cooperation with guide elements.
  • a device comprising a retaining element characterized in that the latter is mounted to rotate upon a support integral with the ramp which effects the release, said ramp being in turn mounted to rotate freely on the intermediate plate in an area located under the sole of the boot.
