Definitions

  • the present invention relates to an adjustment and locking device, particularly suitable for use in ski bindings.
  • ski binding are currently in use which are constituted by a toe unit and a heel unit which are associated in a downward region, by virtue of known types of connecting and fixing means such as screws, bolts, brackets and guides, with a ski or with engagement elements which are in turn associated with said ski.
  • Said heel unit and toe unit are constituted for example respectively by a front jaw and a rear jaw which, together with suitable automatic devices, temporarily lock the tip and heel of the ski boot.
  • These known types of ski binding are adjustable according to shoe size by allowing to move generally the heel unit longitudinally with respect to the ski; this can be achieved by virtue of adjustment means of the screw-and- rack type, as shown for example in US -4,522,422, in which the longitudinal movement of the heel unit is actuated by means of a screw which is arranged below said heel unit and engages a rack arranged on the surface of the ski. A continuous adjustment of the size can be achieved with this device.
  • ski types and in particular recently designed ones, are built so that they have to be used conveniently with a very specific position of the ski boot with respect to said ski.
  • the main drawback of these known types of adjustment device is the fact that said adjustment must be performed within small movements of the heel unit toward the tail of the ski, since an excessive movement would cause an equally excessive displacement of the center of gravity of the user, with consequent difficulty in skiing and a reduction in safety conditions.
  • DE-2,246,668 partially solves the above described drawbacks and discloses a ski binding formed by a toe unit and a heel unit provided with a mechanism for the simultaneous adjustment of the longitudinal position of the toe unit and of the heel unit; said mechanism comprises two connecting elements, one connected to the toe unit and one connected to the heel unit, which are in turn mutually connected by means of an adjustment device which is composed of a rack-and-pinion system.
  • the user may adjust the position of the toe unit and the heel unit is adjusted by actuating the adjustment device which, by virtue of the pinion, acts simultaneously on the two racks, moving the toe unit and the heel unit in mutually opposite directions.
  • these mechanisms transmit the longitudinal motion to the toe unit and heel unit according to a given ratio which is substantially constant with respect to a reference plane pe ⁇ endicular to the longitudinal axis of the ski.
  • the adjustment mechanisms are not universally usable for any type of binding but can be applied only to dedicated bindings interfaced with the adjustment mechanism.
  • the above described adjustment devices comprise devices for locking the adjustment mechanisms usually constituted, for example, by rotating knobs provided in a lower region with a mechanism for actuating the pinion and therefore the racks.
  • the knob can partially slide axially so as to interact selectively with the pinion.
  • the partial sliding of the knob along an axial direction is preferably allowed, for example, in contrast with an elastically deformable element such as a spring.
  • the spring is normally suitable to keep the knob in a position in which it does not interact with the pinion, so as to allow to use the sports implement to practice skiing.
  • the knob If adjustment of the binding is required, one acts by moving the knob axially in contrast with the spring so as to allow connection to the pinion. After turning the knob and therefore completing the adjustment, the spring restores the skiing position, uncoupling the pinion from the mechanism for actuating it.
  • the locking and temporary unlocking of the adjustment device can be achieved by virtue of the interaction between first inclined planes, arranged perimetricaUy to the knob, in a helical pattern, and second inclined planes formed on an element which is rigidly coupled to the adjustment device.
  • DE-2,001,929 discloses a ski binding which comprises a front supporting element, arranged so that it can be adjusted lengthwise on a first base element fixed to the ski, and a rear supporting element, arranged so that it can be adjusted lengthwise on an additional base element which is fixed to the ski, and also comprises an adjustment device in the form of a rack-and- pinion mechanism for the simultaneous adjustment of both supporting elements. Between the supporting elements there are two racks respectively connected to a supporting element and a pinion which meshes with both racks, the racks can be activated manually and can be locked.
  • the pinion has a position, which is raised vertically with respect to the upper part of the ski and allows its rotation, and a locking position, which is compressed against the upper part of the ski.
  • This requires, together with the presence of a pinion activation lever located on a plane which is approximately parallel to the plane of arrangement of said pinion, a considerable overall thickness of the device.
  • the aim of the present invention is therefore to solve the above noted technical problems, eliminating the drawbacks of the cited prior art, by providing a device that allows to modify easily, quickly and continuously the position of the toe unit and heel unit of a ski binding, without altering the position of the foot and body of the user with respect to the center of gravity of the ski.
  • An important object is to provide a device that is compatible with any commercially available type of ski binding. Another important object is to provide a device that keeps the shoe size adjustment device independent of, and isolated from, any function of the toe unit and heel unit.
  • Another important object is to provide a device that ensures high rigidity of the adjustment and locking device, having negligible oscillations or plays of the toe unit and heel unit during skiing.
  • Another object is to provide a device that does not limit the flexural freedom of the ski during use or in any case can have a limited effect on the flexural characteristic of the ski.
  • Another object is to provide a device that is structurally simple, is composed of a small number of components and has a limited thickness.
  • Another object is to provide a device that is free from deformations and has low manufacturing costs.
  • an adjustment and locking device particularly for ski bindings, comprising a first front plate and a second rear plate for supporting respectively a toe unit and a heel unit, characterized in that a third plate is inte ⁇ osed between said first and second plates and has means, which can be activated by the user, for temporary locking to a mechanism which is suitable to coordinate the mutually opposite manual axial movement of said first and second plates.
  • Figures 1 and 2 are respectively a bottom view and a plan view of the device according to the invention, shown without the lower covering panel;
  • Figure 3 is an exploded perspective view of the device
  • Figures 4 and 5 are bottom views of the locking means and of the mechanism with which it interacts, arranged in two different positions, respectively for adjustment and for skiing;
  • Figure 6 is a perspective view of the locking means arranged in the skiing position
  • Figure 7 is a bottom perspective view of the pair of pinions;
  • Figure 8 is a perspective view of the second pivot;
  • Figure 9 is a sectional front view of the locking means. Ways of carrying out the Invention
  • the numeral 1 designates an adjustment and locking device, particularly usable for ski bindings, comprising a first front plate and a second rear plate, 2a and 2b respectively.
  • the plates have a transverse cross-section shaped like an inverted C and are respectively and slidingly associable at two underlying and complementarily shaped first and second ends, 3a and 3b, of a third plate 4.
  • the first and second ends 3a and 3b have a plurality of holes 50 for detachable connection, by means of a plurality of respective screws 51, to the underlying top surface of a ski, not shown in the figures.
  • the first and second plates 2a and 2b act as a support respectively for a toe unit and a heel unit of a per se known type, which are not shown in the figures and are suitable to temporarily lock respectively the tip and heel of a ski boot.
  • the stroke of the first and second plates 2a and 2b along the first and second ends 3a and 3b of the third plate 4 is delimited respectively by a first abutment surface 5a and a second abutment surface 5b, provided, for example, by tapering the first and second ends 3a and 3b with respect to a central body 6 of the third plate 4.
  • a compartment 7 is formed in the central body 6 and is adapted to contain a mechanism 8 suitable to coordinate the mutually opposite axial movement of the first and second plates 2a and 2b.
  • the compartment can be closed by means of a lower covering panel 6a and an upper covering panel 6b.
  • the first and second abutment surfaces 5a and 5b are provided, as shown in Figure 3, at the free ends of the upper covering panel 6b.
  • Figures 4 to 6 show how the mechanism 8, suitable to coordinate the mutually opposite axial movement of the first and second plates 2a and 2b, comprises an upper pinion 9a and a lower pinion 9b which is smaller than the upper one.
  • the pinions are superimposed and rigidly associated, or monolithic, with respect to each other and are centrally provided with a first hole 14 which engages a first pivot 15 allowing a rotation of the pinions.
  • the first pivot 15 has a vertical axis and is arranged centrally in the central body 6, preferably by means of the connection of a third lower end thereof 15a, in a complementarily shaped first seat 16 formed in said central body 6.
  • the first pivot 15 is provided, in an upper region, with a first head 15b, which prevents any extraction of the pair of pinions 9a and 9b, because the upper covering panel 6b rests on the head.
  • the lower pinion 9b engages first and second elements 10a and 10b, for connection to the first and second plates 2a and 2b.
  • Each of said first and second connecting elements 10a and 10b is constituted by a blade which is approximately S-shaped.
  • the blades are connected, at a first free end 11a and lib, respectively to the first and second plates 2a and 2b, and the connection is obtained, in this particular embodiment, by means of a first rivet and a second rivet, designated by the reference numerals 13a and 13b.
  • the first and second connecting elements 10a and 10b have a lateral rack suitable to interact with the teeth of said lower pinion 9b.
  • the toe unit and heel unit may be locked into position by locking the upper pinion 9a, which is rigidly associated with the lower pinion 9b.
  • Said locking is performed by temporary locking means, constituted by a first pawl 17a and a second pawl 17b, having an approximately triangular or teardrop-like or cam-like plan shape and centrally provided respectively with a second hole 18a and with a third hole 18b, for connection to a second pivot
  • the first and second pawls 17a and 17b are arranged on a horizontal plane, preferably in mutually mirror-symmetrical positions, and can rotate in opposite directions about the second and third pivots 19a and 19b.
  • the mutual rotation of the two pawls is coordinated by the presence of two or more teeth, generally designated by the reference numeral 20, which protrude radially from each one of the first and second pawls 17a and 17b and are arranged mutually side by side in the locking condition.
  • the teeth 20, by interacting with each other, coordinate and render symmetrical, with respect to a vertical longitudinal plane, the rotary motion imparted to one of the pawls.
  • the third pivot 19b is preferably cylindrical and is shaped complementarily to the third hole 18b, which is circular, so as to allow a rotation of the second pawl 17b about the third pivot.
  • Said third pivot 19b can be accommodated, at a fourth lower end 21a, in a complementarily shaped second seat 22 formed in the central body 6.
  • the third pivot 19b is also provided, in an upper region, with a second head 21b which prevents the extraction of the second pawl 17b from the third pivot.
  • the second pivot 19a has a shape, shown in Figure 8, which features a fifth lower end 23a which is cylindrical so that it is rotatably associable in a complementarily shaped third seat 24 formed in the central body 6.
  • the second pivot 17a has a prism-shaped region 25 for a non-rotating connection to the first pawl 17a.
  • the second hole 18a of the pawl is in fact shaped complementarily to said prism-shaped region 25.
  • the second pivot 19a has a sixth upper end 23b which is also preferably prism-shaped so that it can engage in a non-rotating fashion a complementarily shaped fourth seat 26 formed in the lower surface of a lever 27.
  • the lever 27 can be accommodated in an opening 28 which is formed in the upper covering panel 6b.
  • the shape of said opening 28 is such that when the adjustment and locking device 1 is assembled, the lever 27 cannot be directly disconnected from the second pivot 19a.
  • a tab 29 protrudes laterally from the lever 27 and allows the user to turn the lever 27.
  • the second pivot 19a is made to turn and therefore the first pawl 17a also is made to turn by virtue of the nonrotating connection in the prism-shaped region 25.
  • the rotation of the first pawl 17a is accompanied, by means of the teeth
  • the coordinated motion of the pawls is affected by the presence of an elastically deformable element 30, such as for example a wire spring, which is associated, at its free ends, with a fourth hole 31a and a fifth hole 31b, which are shaped complementarily and are formed proximate to the second and third holes 18a and 18b.
