Definitions
- the present invention relates to a safety binding, and more particularly to a ski-binding.
- Known safety bindings usable in skis are currently usually constituted by a heel element and by a tip element, both of which are associated with the ski and are suitable for allowing the engagement of the usually standard ends of a ski boot.
- Known heel elements in fact usually comprise a lever provided with a jaw which interacts with the heel region of the boot.
- Said heel elements furthermore have means for releasing the boot when the jaw is subjected to a force greater than a set value.
- a disadvantage of said known types of binding is constituted by the fact that, in order to open the binding, and in particular a heel element, it is indispensable to impart to the lever a force which must overcome the loading force of an adapted spring arranged inside said heel element.
- the aim of the present invention is therefore to eliminate the disadvantages described above in known types by providing a binding wherein it is possible to easily achieve both release and resetting, requiring a modest effort which in any case is smaller than the load which is or can be imparted to a spring which interacts with a jaw for locking an item of footwear.
- Another important object is to provide a binding in which the skier can secure the boot to said binding in an easy manner and therefore without stooping or manual efforts applied directly to a lever.
- Another important object is to provide a binding which is structurally simple and compact.
- Not least object is to provide a binding which associates with the preceding characteristics that of being reliable and safe in use.
- a safety binding particularly for skis, characterized in that it comprises a rear coupling means constituted by a first body, slidably associated with a base, said base being associated with said ski, a lever being connected to said base proximate to an end which is accessible to the user, said lever being associated with a jaw engaging the heel of an item of footwear, said lever being furthermore rigidly associated with first means, said first means being pivoted to said jaw and being adapted to activate second means suitable for allowing automatic resetting after a safety release.
- the reference numeral 1 generally indicates a rear coupling means, hereinafter also termed heel element, of a safety ski-binding which is constituted by a first body, indicated by the reference numeral 2, which is slidably associated with a base 3 adapted to be rigidly associated with a ski.
- the rear coupling means 1 comprises a lever 4 which is connected to the first body 2, by means of a transverse first pivot 5, at an end 6 thereof which can be accessed by the skier.
- the lever 4 is substantially U-shaped with wings 7a and 7b directed toward the underlying base 3 and toward the tip of the ski and inclined along a plane which forms an acute angle with said base.
- the base 8 of the lever 4 is shaped so as to constitute an activation pushbutton for the skier.
- the lever 4 has, at the first pivot 5, a slot 9 which is advantageously curved with a concavity directed toward the base 8.
- first means which are constituted by a pedal 10 which has, at its free ends, a head, indicated by the numeral 11, which has a substantially triangular configuration with the vertex directed opposite to the heel 12 of an item of footwear, such as a ski boot, and is pivoted proximate to the base transversely to a jaw 13 at a second pivot 14.
- the pedal 10 can have one or more first rollers 15 at the connecting base between the wings; said rollers interact with at least one first inclined plane 16 which is connected, by means of an adapted first tab 17, to the end of a first adjustment screw 18, the head 19 whereof is rotatably associated at an adapted threaded hole defined in a wall 20 which protrudes rearward with respect to the base 3.
- a cylinder 22 is associated at the stem of the first screw 18 inside a first cavity 21 arranged above said base 3, and a first spring 23 abuts thereon; at the other end, said first spring interacts with a second tab 24 of said first body 2 which protrudes toward the base 3 and is appropriately perforated for the passage of the first screw 18.
- Said second tab 24 is interposed between the end of the first screw 18 which is connected to the first tab 17 and the cylinder 22.
- the first screw 18 allows to adapt the binding to the length of the sole of the item of footwear, since it is possible to move the first body 2 backward, thus increasing the interspace for the mating of the sole with the binding.
- the presence of the first spring 23 allows the elastic recovery of the rear coupling means 1.
- the pedal 10 protrudes beyond the jaw 13 and can be activated directly by the sole of the item of footwear when the lever is open.
- the end of the pedal 10 may not have the first rollers 15, the interaction of the heel of the boot with the jaw 13 occurring by means of an adapted fixed tab which protrudes from said jaw in a region adjacent to the base 3.
- the ends of the heads 11 of the pedal 10 interact with an adapted pair of lugs 25a and 25b which protrude downwardly with respect to a pair of connecting rods 26 which are freely pivoted, at the other end, at an adapted third pivot 27, to the jaw 13.
- Second rollers 28 are present proximate to each lug of said pair of lugs 25a and 25b on each of said connecting rods 26, and slidably interact with an underlying side of the heads 11 of the pedal 10.
- a second spring 29 is arranged coaxially to the third pivot 27 for the pivoting of the pair of connecting rods 26 to the jaw 13, and abuts at the underlying first body 2; said second spring 29 is loaded during the last section of the counter-clockwise rotation which can be imparted to the pair of connecting rods 26, as described hereinafter.
- the rear coupling means 1 furthermore comprises a cam 30 which is accommodated within an adapted second cavity 31 which is defined inside the first body 2 and is arranged above the first cavity 21.
- a third spring 32 abuts inside the second cavity 31 at the cam 30 and controls, by means of the adjustment of a second screw 33 which is accessible from the outside of the first body 2, the release of the rear coupling means 1 of the item of footwear in extreme conditions.
- the cam 30 furthermore interacts directly with the ends of the pair of connecting rods 26 which have the second rollers 28.
- the rear coupling means 1 furthermore comprises, at the first pivot 5 for connecting the lever 4 to the first body 2, a fourth spring 34 for contrasting the closure of the jaw 5.
- the operation of the rear coupling means 1 is therefore as follows: considering the position shown in figure 1, and therefore with the lever 4 closed and with the item of footwear associated with the binding, the lever 4 rotates with respect to the second pivot 14 upon a pressure imparted by the skier at the base 8, thus disengaging the pair of lugs 25a and 25b from the ends of the heads 11 of the pedal 10.
- the second spring 29 is unloaded completely until it separates from the underlying first body 2 and thus rotates together with the pair of connecting rods 26.
- Said connecting rods during the step of complete opening, move away from the internal wall of the jaw 13 simply by gravity, since they are no longer subjected to the effect of the second spring 29.
- the rear coupling means is thus ready to be coupled to the boot again.
- the third spring 32 does not contrast the first step of the rotation, since the pair of connecting rods 26 does not press at the cam 30, as the lugs 25a, 25b and the ends of the heads 11 of the pedal 10 are not mutually engaged.
