Definitions

  • the present invention relates to a multi -position heel piece for ski mountaineering bindings .
  • safety bindings comprising a front part or toe piece, able to lock the toe of the boot, while allowing rotating thereof about a substantially horizontal axis, and a rear part or heel piece, able to co-operate with the heel of the boot so as to allow three different modes of use, i.e. : heel released (walking) , heel resting with greater/lesser inclination of the boot (uphill) , and heel locked (downhill) .
  • the technical problem which is posed, therefore, is to provide a ski binding heel piece able to perform:
  • Figure 1 shows an exploded view of the heel piece according to the present invention
  • Figure 2 shows a side view of the heel piece during closing onto the heel of the boot (downhill) ;
  • Figure 3 shows a schematic cross-section along a longitudinal vertical plane indicated by the line III- III in Fig. 2 ;
  • Figure 4 shows a side view of the heel piece during insertion of the boot
  • Figure 5 shows a side view of the heel piece in a first raised position of the heel (released for walking) ;
  • Figure 6 shows a side view of the heel piece in a second raised position of the heel;
  • Figure 7 shows a side view of the heel piece in a third raised position of the heel .
  • the heel piece according to the present invention comprises:
  • a fixed base piece 10 elongated in the longitudinal direction and formed by a perimetral frame 11 which defines two internal seats, i.e. a front seat 12 and rear seat 13, which are open in the vertical direction Z-Z; the longitudinal arms 11a of the frame 11 are provided with holes 14 having a vertical axis for fixing the base piece to the ski (not shown) by means of screws 14a;
  • said openings 12,13 in the base piece form a corresponding number of guides for:
  • a slide 20 movable in both senses of the longitudinal direction by means of conventional screw means 25 which, passing through the rear transverse side of the base piece 11, co-operate with a nut 25a which is fixed to the said slide so that rotation of the screw causes displacement of the slide.
  • the front part of the slide has, formed .thereon, a step 22 covered by a reinforcing cover piece 23 fixed by- means of a vertical screw 23a for resting- the heel Ia 5 of the boot; it is also possible to insert shims 22a between the step and the cover piece in order to adjust 'precisely the height of the heel.
  • the slide 20 also has at the rear a body 24 having, 10 formed therein, a hollow cylindrical seat 26 which is designed to form the seat for resilient means 30 • comprising a spring 31 which is fixed under compression inside the seat 26 between a top closing cap 33 with a thread 33a which can be screwed into a female thread 15 26a of the seat 26 and a bottom shaped foot 32.
  • the shaped foot 32 has undercuts 32a in the longitudinal and transverse directions, able to allow seating of a longitudinal lever 34 mounted on a cross-
  • the bracket 130 forms the first component of a
  • kinematic chain for transmitting the manoeuvring forces of the heel piece; said chain comprises:
  • a rear lever 120 which can be operated by the user and rotates on the bracket 130;
  • a front rotating engaging member 110 which is designed to engage with the heel Ia of a boot 1 and in turn rotates on the bracket 130;
  • the rear operating lever 120 is formed in the manner of a fork with parallel arms 121 which have respective holes 121a through which the said pin 34a passes, said pin also supporting the lever 34 and being used to pivotably hinge the lever 34 on the bracket 130;
  • the lever 120 has a seat 120a formed at the free end and designed to form a part for gripping by the user;
  • the front engaging member 110 is pivotably mounted on the front end of the arms 130a of the bracket 130 by means of respective holes 132 passed through by a pin 114 which also passes through the front engaging member 110 via respective holes Ilia in its arms 111;
  • a substantially L- shaped transverse body 112 is arranged between the said arms 111, the longitudinal arm 112a thereof being designed to co-operate with the said lever 34 which has the function of keeping the engaging member 110 in the correct position when the latter tends to rotate owing to the deformations resulting from the dynamic stresses of the ski;
  • the vertical arm 112b of the L is instead designed to cooperate with an inclined surface 27a ' of a nose 27 which extends from the body 24 towards the front;
  • the arms 111 of the engaging member 110 are also provided with two further holes 113 inside which the first front end 140a of each connecting bar 140 is pivotably mounted, while the other rear end 140b is designed to be inserted inside suitable openings 122 in the arms 121 of the lever 120, thus closing the kinematic chain which will transmit the movement from the operating lever 120 to the front engaging member 110, as will emerge more clearly below with reference to operation of the heel piece.
  • the bottom end of the lever 120 is formed in the manner of a cam 123 consisting of a first surface 123a which is substantially parallel to the longitudinal direction X-X, a second surface 123b, forming an obtuse angle with said first surface 123a, and a third surface 123c, forming an obtuse angle with said second surface 123b.
  • the bottom end of the arms 111 of the engaging member 110 has a respective cam 115 formed by a first surface 115a substantially parallel to the longitudinal direction X-X and a second surface 115b forming an acute angle with said first surface 115a.
  • the heel piece is arranged in the open • configuration (Fig. 4), rotating the lever 120 downwards so that the engaging member 110 is totally rotated towards the rear, pulled by the connecting bars 140;
  • the heel piece (Fig. 2) and the heel piece is closed by raising the lever 120 via the seat 121 so that the upwards rotation produces a thrust which forces the engaging member 110 to rotate towards the heel of the boot until the respective surfaces 123a, 115a of the cams 123,115 of the lever 120 of the engaging member 110 assume the longitudinal position, resting on the base piece 10; in this position the heel piece is ready for downhill use;
  • the pulling force exerted by the boot 1 on the engaging member 110 causes raising of the engaging member by means of rotation of the bracket 130; the engaging member therefore disengages from the lever 34 and brings the top end of the vertical arm 112b of the transverse body 112 into contact with the inclined surface 27a of the nose 27 which, with continuation of the pulling action of the boot, causes the engaging member 110 to rotate towards the rear, disengaging from the heel Ia and freeing the boot which in this way is able to come out of the heel piece freely.
  • the heel piece according to the present invention while ensuring a high rigidity and absence of play in the transverse direction compared to the known bindings of the art, forms a particularly light assembly which is simple to use, allowing fast change-over of the configuration by means of the rear lever which can be operated also using a ski stick without the user having to bend down, this solution being particularly useful in the working conditions which are typical of ski mountaineering.
  • the heel piece according to the invention incorporates the system for vertical release which is caused by the retracting/rotational action of the heel piece, said action in turn causing compression of the reaction spring.
  • This vertical release system constitutes an obvious improvement in the sector of ski mountaineering also in view of the simple design and lightness of the assembly.
  • the heel piece according to the invention is also envisaged being able to associate the heel piece according to the invention with a plate made of rigid material and designed to be fastened to the heel of the boot so as to able to ensure more precise interference between the boot and the engaging member of the heel piece, resulting in greater engaging/disengaging precision.
  • Said plate may also be fitted to the boot or form an integral part thereof .
