Definitions
- the invention relates to a boot-binding assembly for skiing, in particular cross-country skiing.
- the invention relates more particularly to a cross-country ski boot comprising at its end a part intended to engage in the binding.
- Devices of the kind in question are known and are described, for example, in the US patents 2,991,086, 2,994,543, 3,603,606, 4,004,823, 4082312, 4,129,319, 4,146,247, 4,184,696, 4,219,216, or even in French patents 824,863, 2,304,368 and 2,447,731.
- fasteners made in this way present problems due to wear, erroneous foot engagement or many other well known causes.
- Other types of fastening include visible helical springs which can unfortunately be quickly hindered by snow and ice, which makes the fastening operation always difficult. In this way, current fasteners have many drawbacks.
- the invention overcomes these drawbacks. It relates to a shoe-binding assembly which is relatively simple, easy to maneuver and has excellent behavior when skiing.
- the boot-binding assembly generally refers (1) is intended to fix the end of a cross-country ski boot (2) (3) on a ski ( 4).
- the end (2) of the shoe (3) is equipped with a generally T-shaped part, referenced (5), extending forward.
- This part (5) comprises a flat metal branch (6) which defines the stem of the T as well as a transverse branch (7) which defines the arms of the T.
- the branch (7) is mounted firmly in a loop (8 ) at the outer end of the branch (6).
- the internal portion (9) (see FIG. 3) of the upper (6) is molded in the sole (10) of the ski boot (3).
- the binding (1) comprises a body 11 of generally rectangular shape which has a T-shaped groove (12) arranged in the vicinity of the side located near the shoe intended to receive the T-shaped part (5).
- a recess (13) is provided behind the slot (12) to receive a screw (14) intended to fix the body (11) on the ski (4).
- the screws (15) also serve to fix the body (11) to the ski (4).
- This body (11) is made of rigid and hard plastic.
- a rectangular metal plate (16) is interposed between the body (11) and the ski (4). This plate (16) extends from the front to the rear of the body (11). The rear end of this plate (16) is fixed to the ski (4) by screws (17).
- a steel leaf spring (18) is sandwiched between the body (11) and this plate (16).
- This spring (18) has a general L shape and is bent upwards in the rest position with a curvature allowing it to match the front face (20) of the body (11).
- a handling member (21) also made of rigid plastic, is provided at the end of the arm (19) of the spring (18) to approach or distance the latter from the front face (20) of the body (11).
- This handling member (21) has a general V shape with a large head (22) defining an arm and a notch (23) disposed between the arms (22) and (24).
- a groove (25) is provided at the rear of the head (22) to receive the end of the vertical arm (19) of the spring (18).
- a lever (26) defined by a rectangular metal plate is also fixed in the groove (25). This lever (26) is sandwiched between the arm (19) of the spring (18) and the front end (20) of the body (11).
- the handling member (21) and the lever (26) extend over the entire width of the body (11).
- a pair of pins (27) which are formed by the branches of a U-shaped rod (28) are slidably mounted in the body (1 1) so that their sliding movement allows either to engage or disengage ( Figure 1) or maintain ( Figures 2 and 3) the part attached to the end of the shoe, in other words, allows to move from the retained position to the release position.
- the base (29) of this rod (28) is arranged opposite the lever (26) and the arm (19) of the spring (18), the pins (27) extending through the spring, the lever and the body .
- the free ends of the pins (27) are arranged above the branches of the T-shaped groove (12) in the vicinity of the end of this groove.
- pressure is applied, for example using the tip of a ski pole, to the handling member (21) and more precisely to the rear of the notch ( 23).
- the pressure exerted forces the lever (26) to pivot around its rear stop by pushing the manipulation member (21) and the arm (19) of the spring (18) away from the face (20) of the body ( 11).
- This movement of the manipulation member (21) of the lever (26) and of the spring (18) forces the pins (27) to withdraw from the extended position (FIGS. 2 and 3) to the retracted position (FIG.
- the lever (26) is essentially intended to easily band the spring (18) to communicate a movement intended to move the branch (19) of the spring (18) from the front face (20) of the body (11). If it is obvious that such a spring is useful, it is not essential and can therefore possibly be deleted.
- the binding in question is of the so-called semi-automatic fitting type, since to do this it is sufficient for the skier to simply press the rod (7) of the piece (5) against the pins (27) to open the binding.
- the free ends of the pins (27) are rounded or even better bevelled.
- the pins are then forced backwards by pushing the spring (28) thus allowing the rod (7) to be completely introduced into the groove (12).
- the spring (18) returns to its initial position and thus keeps the part (5-7) in the retaining position ( Figures 2 and 3). To release the binding, it suffices to exert, as already said, downward pressure on the handling member (21).
- This rocker lever (31) has on the front a hole (32) intended to receive the tip of the ski pole (40) in order to allow putting on and taking off.
- a U-shaped slide member (27) slides in the body (11) in a horizontal plane passing through two horizontal channels. (42) formed for this purpose in the body (11) and the ends of its two branches (28), which are bevelled (41), open into the slot (34) just in the middle of this slot.
- the plane where these ends (38) open is located relative to the bottom of the transverse slot (34) at a height equal to the diameter of the axis (7) so as to allow the rotation of this axis (7) in the slot transverse (34).
- connection portion (29) of the two branches (28) of the sliding U is engaged in a transverse slot (37) formed for this purpose on the rear face of the rocker lever (31).
- This transverse slot (37) is located in the lever (31) just in front of the slot (39) where the vertical branch (19) of the spring (18) is inserted.
- the rear face (33) of the rocker is disposed substantially perpendicular to the rear face of the transverse slot (34) formed in the body (11).
- the length of the branch (6) of the T-shaped piece attached to the front of the shoe (3) has a length greater than the distance between the middle of the distance between the underside of the branch (28) and the bottom of the slot (34) and the rear face (43) furthest back from the rocker (311.).
- the length of the branch (6), calculated from the tip of the shoe to the middle of the axis of the transverse branch (7) is 30 millimeters, while the distance between the face rear of the rocker lever and the middle of the transverse slot formed in the body fixed on the shoe relative to the plane where the branches of the sliding member open is equal to 25 millimeters.
- the beveled end (41) of the branches (28) does not substantially exceed the middle of the axis (7), in order to facilitate the penetration of the shoe into the binding while reducing the shearing forces and reducing the travel of the U-shaped sliding fork (27) during heaving.
- Figure 8 shows in summary perspective view the elements used for the implementation of the invention, it being clearly specified that the bran horizontal che (18) of the spring (20) engaged in the rocker lever (31) is fixed to the ski (4) by fixing screws (15) not shown passing through the body (11).
- the tip (43) of the sole (10) is slightly inclined 45 downwards and on this inclined portion (43) is engaged a screw (44) whose end threaded (45) can be adjusted in height in the thread (46).
- this screw (44) which will come to bear on the rear face (33) of the rocker lever (31).
- the shoe-binding assembly according to the invention is simple, economical, easy to handle, not very sensitive to snow and ice. It also requires no particular effort to be maneuver since the putting on and taking off takes place semi-automatically.
- the rotation of the ski boot is therefore about a pivot axis perfectly centered and maintained throughout the practice of skiing. This axis is precise and is geometric.
- This rotation on the one hand does not induce any unnecessary effort, and on the other hand does not hurt the toes.
- the assembly due to its design ensures perfect support of the feet in the longitudinal axis of the ski, and this, without using special guides such as notch or ridge, placed on the ski and under the sole.
- the improved version makes it possible to carry out a safety bottom fixation, during falls before, which we did not know how to do until then.
- this shoe-binding assembly is particularly advantageous for the practice of cross-country skiing.
