Definitions

  • ABSTRACT The device comprises at least two cooperating profiles, one male, the other female; one profile is integral with the ski, the other integral with the boot.
  • the female profile extends in the longitudinal direction of the element with which it is integral and includes at least one passage defined by two lateral faces, the passage running substantially in the longitudinal axis of the element and having at least one of its ends open to receive themale profile.
  • the cooperation of the male and female profiles ensures correct positioning of the boot in relation to the ski by substantial displacement in the plane of the latter before the ski is finally fitted.
  • the present invention relates to a device for guiding and centering a boot on a ski prior to the locking operation, or before the boot is put on with the ski, this operation being carried out by means of a system for retaining the boot in its correct position with which the ski is equipped, and which is designed to release automatically whenever a load of a predetermined value is applied by the boot to the retaining system.
  • the present invention provides a simple and reliable device for correctly pre-positioning the boot, the device being intended for use more particularly with bindings of the type comprising parts fitted to the sole of the boot.
  • the device consists of at least two cooperating profiles, onemale and one female, one of which is integral with the ski and the other integral with the boot.
  • the female profile extends over the length of the element with which it is integral and comprises at least one passage defined by two lateral surfaces, the passage running substantially in the direction of the longitudinal axis of the element and having at least one of its ends open to receive the male profile.
  • This device may be adapted to bindings which are fitted by engaging to toe of the foot with a resilient stop and then sliding the foot longitudinally, in the plane of the ski, until a rear part engages under a part of the heel piece. It will be understood that the cooperation between these male and females profiles will ensure cor.- rect positioning of the boot in relation to the ski when the boot is moved in the plane of the ski, the guiding device forcing the boot to position itself accurately in the longitudinal axis of the ski. As a variant, the forward stop and the heel piece may be interchanged.
  • the male profile may be integral either with the ski or the boot; the female profile will naturally be located on the other element.
  • the lateral surfaces defining the female profile are parallel with each other and with the longitudinal axis of the element, the distance between the surfaces being slightly greater than the width of the male profile, in order to allow the two profiles to slide easily in relation to each other.
  • the passage in the female profile opens towards the male profile by diverging from the longitudinal axis of the element.
  • this female profile is shaped like a funnel, the mouth of which constitutes a reception area for the male profile.
  • This reception area provided by the female profile may, with advantage, extend over most of the width of the boot or the ski, in order to allow the profiles to cooperate, even if the boot is first of all placed obliquely.
  • the male profile may, with advantage, be in the form of a projecting stud. If there is only one such stud, it will be located on the longitudinal axis of the element of which it is an integral part.
  • two or more studs of this kind may be used, in which case the female profile will have the same number of passages.
  • the profile integral with the boot may be incorporated directly into the lower surface of the sole of the boot or, if use is made of a plate temporarily fitted under the sole of the boot, it may be fitted to the lower surface of the plate.
  • the male profile may be of any desired crosssection, namely triangular, quadrangular, prismatic,
  • FIG. 1 is a side elevation of a first embodiment of the invention, in which the female profile is located within the thickness of the sole of the boot;
  • FIG. 2 is a section along the line II-II in FIG. I;
  • FIG. 2a is a variant of the device in FIGS. 1 and 2;
  • FIGS. 3 and 3a illustrate a second embodiment of the invention, FIG. 3 being a side elevation of the sole of a boot fitted with a projecting stud, while FIG. 3a is a plan view of the ski showing the female profile;
  • FIG. 4 is a plan view of the ski according to another embodiment of the invention, in which the female profile contrived in the ski is designed to cooperate with two projecting studs on the boot;
  • FIG. 5 is an exploded perspective view of another form of execution of the invention in which use is made of an intermediate plate temporarily secured to the boot;
  • FIG. 5a is a variant of the device in FIG. 5;
  • FIG. 6 is another embodiment of the invention using an intermediate plate
  • FIG. 7 is a partial plan view of FIG. 6, with the boot removed;
  • FIG. 8 is a bottom view of another variant of a plate binding.
  • a forward stop 1 attached to a ski 2 and comprising a piston 3 which is caused to project by means of a spring 4; and a heel piece or catch 5 attached to the ski by screws 6.
  • the forward stop cooperates with a part 7 of substantially V-shaped horizontal cross-section and integral with the tip of the boot, whereas catch 5 cooperates with a part integral with the back of the boot having a sloping upper surface 9 and lateral surfaces 10.
  • this rear part 8 engages under catch 5 like a wedge.
  • the guiding device in the embodiment illustrated in FIG. 1, elements 7 and 8 have been considered as being secured directly to the sole of the boot.
  • the guiding device consists of a male profile ll integral with the upper surface of the ski and in the form of a cylindrical stud located on the longitudinal axis X-X of the ski (FIG. 2).
  • Female profile 12 is contrived directly within the thickness of the sole of the boot and has a receiving area 13 for the male profile 11 formed by a cut-out at right angles to the boot. This area is defined rearwardly by a wall 14 and forwardly by two lateral surfaces 15 and 16 which are curved and converge towards the longitudinal axis of the boot.
  • Area 13 is extended in the forward direction bya passage in the form of a throat l7 accommodating male profile 11.
  • front wall 18 of throat 17 is chamfered, so that any snow accumulating in the female profile can be removed from the useful zone of throat l7.
  • FIG. 2a is a diagrammatic representation of a variant of the system shown in FIG. 1, in which male profile lla, which is in the form of a cylindrical stud, for example, is of a diameter scarcely less than the width of the ski 2a.
  • the female profile contrived in the bottom of the sole of the boot has a throat 17a occupying almost the total width of the sole and defined by two narrow lateral wings 17b, 17c having parallel sides and flat or slightly rounded ends.
  • Throat 17a opens out into an area 13a of large dimensions. It will be understood that when the sole is out of alignment as shown in FIG. 2a, the end of wing 17c rests against the rounded wall of stud 11a on which it slides in the direction of arrow F when the forward stop applies a thrust in the direction of arrow F the boot is thus positioned automatically.
  • pivot could also be in the form of a part mounted to rotate about a vertical axis, in order to assist part 170 to slide.
  • FIGS. 3 and 3a show a variant in which cylindrical stud 21 is attached to the sole of the boot and the female profile is contrived in the ski.
  • This female profile may, with advantage, have an area 22 for the reception of male profile 21 which is defined forwardly by a vertical wall 23 and laterally by two surfaces 24 converging towards the axis of the ski. Area 22 is extended by a central throat 25 opening into a transverse channel 26.
  • stud 21 performs no function after the ski has been put on.
  • FIG. 4 shows a ski comprising a female profile adapted to cooperate with two studs located on the sole of the boot and shown diagrammatically at 27 and 28.
  • the female profile has an area 29 for the reception of the studs, two lateral surfaces 30, 31 to guide the studs towards the axis of the ski, and two throats 32, 33 in which studs 27, 28 engage when the boot moves on the ski.
  • Throats 32, 33 open into a transverse channel 34 for the release of the studs.
  • FIG. 5 illustrates an arrangement having an intermediate plate 35 fitted to the sole 36 of the boot 37.
  • the plate comprising a forward jaw 38 for the accommodation of the toe 39 of the boot, and a locking system 40 consisting of a stirrup mounted to pivoton the rear end of plate 35 and equipped with a locking cam 41 which cooperates with the back of the boot.
  • a strap 48 secured to jaw 38 of the plate makes it possible to secure the boot to the ski, buckle 43 being hooked to the ski by means of a device not shown.
  • Thus unit is designed to be inserted between forward stop 1 and rear catch 5 of the binding.
  • the guiding device provided in this case consists of a cylindrical stud 45 secured to the ski and designed to cooperate with a cut-out 46 at the rear end of plate 35.
  • This cut-out may have two curved surfaces diverging towards the rear in the form of an axial throat 48 in which stud 45 is accurately accommodated.
  • Front surface 49 of the throat may be chamfered to facilitate the removal of any snow or mud lodging between the plate and the ski.
  • the rear end of plate 34 engages under catch 5 by reason of the wedge shape imparted to the wings of the plate.
  • FIG. 5a shows a variant of the device in FIG. 5 comparable with the variant in FIG. 2a.
  • cylindrical stud 45 (possibly pivoting about its vertical axis) is slightly smaller in diameter than the width of plate 35a, which is similar to plate 35.
  • the said plate 35a has only one throat having parallel sides 46a and terminating in a semicircular part 49a. In other words there is no need for converging sides similar to sides 47 of the device in FIG. 5.
  • wings A A at the end of the plate will be very narrow and they will be preferably, but not necessarily, rounded off, in order to make it easier for stud 45a to slide.
  • FIGS. 6,7,8 also illustrate plate bindings.
  • square stud 50 is integral with ski 2 and cooperates with a female profile in the interior of plate 51.
  • This female profile comprises a receiving area 52 defined by lateral surfaces 53 which are curved and converge towards the axis of the plate, the area 52 opening into a transverse channel 54, the front face of which is preferably chamfered.
  • FIG. 7 shows, in full lines, the position of the plate immediately before it is put on and, in dotted lines, its position after it has been put on.
  • receiving area 56 in the plate extends over a substantial length thereof, terminating towards the front end in curved, converging surfaces 57 opening into an axial passage 58 which, in turn, opens into an area 59 covering practically the whole width of the plate.
  • FIG. 8 shows three successive positions of the plate in relation to stud 60, as the boot is being fitted.
  • the male element could be cylindrical, but in that case the skier would have to ensure that the boot and the ski were coaxial, and he would have to maintain this coaxiality while putting the ski on. With a square profile, however, this coaxiality may be achieved simultaneously with the pre-centering operation.
  • a device for guiding and centering a boot in relation to a ski, prior to the ski-fitting operation carried out by binding means adapted to fasten the boot firm in position on the ski and to release said boot automatically under predetermined loads said device comprising: at least two cooperating male and female profiles, one of said profiles being secured to the ski, the other of said profiles being secured to the boot; said female profile extending in the longitudinal direction of the element to which said female profile is secured and including at least one passage defined by two lateral surfaces, said passage running substantially in the longitudinal axis of said element and having at least one end open to receive said male profile, said male and female profiles alllowing a longitudinal sliding displacement of said boot on said ski to thereby provide a correct positioning of the boot in relation to the skibefore said bootis fastened firm to said ski by said binding means.
  • a device wherein said passage in said female profile opens, at the end where said male profile is introduced, into an area defined by two walls diverging from the longitudinal axis of said element.
  • a device according to claim 2 wherein said passage has a width slightly greater than the transverse dimension of said male profile to allow the displacement thereof when the device is in operation.
  • said male profile consists of a single projecting stud located on the longitudinal axis of said element.
  • a device wherein said passage in said female profile opens, at the end where said male profile is introduced, into an area defined by two walls diverging from the longitudinal axis of said element; said female profile including a single straight passage in the longitudinal axis of said element.
  • said male profile consists of a plurality of projecting studs, said female profile exhibiting a plurality of straight passages parallel with the longitudinal axis of said element.
  • said male profile consists of a part integral with the upper surface of the ski and projecting upwardly.
  • a device wherein the sole of the boot is integral with a temporarily fitted intermediate plate, said female profile being contrived in the lower surface of said plate.
