Description
- The present invention relates to the technical sector concerning ski mountaineering bindings, with particular reference to a toe-piece of the ski binding.
- ITM020070365 describes a toe-piece of a ski binding for ski mountaineering, which comprises: a base which is fixable to a ski; a first jaw which is coupled in a revolute pair to the base so as to rotate with respect to a first axis of rotation which is parallel to the axis of the ski when the base is fixed to the ski; a second jaw which is rotatably coupled in a revolute pair to the base with respect to a second axis of rotation which is parallel to the first axis of rotation; a first pin which is borne by the first jaw for inserting in a first lateral hole fashioned in a tip of a ski boot; a second pin which is borne by the second jaw for inserting in a second lateral hole opposite the first lateral hole fashioned in the tip of the ski boot; an activating lever which is coupled in a revolute pair to the base with respect to a third axis of rotation which is perpendicular to the first axis of rotation; a joint which is activatable by the activating lever and which in turn comprises a first portion of joint, which is connected to the first jaw, and a second portion of joint, which is connected to the second jaw and which is coupled to the first portion of joint; a first spring which is interposed between the first jaw and the first portion of joint; a first pin seat fashioned in the first jaw; a second pin seat fashioned in the first portion of joint; a first pin which is arranged slidably between the first pin seat and the second pin seat, and which is arranged at the axis of the first spring to maintain the first spring in guide; a second spring interposed between the second jaw and the second portion of joint; a third pin seat fashioned in the second jaw; a fourth pin seat fashioned in the second portion of joint; a second pin which is slidably arranged between the third pin seat and the fourth pin seat, and which is arranged at the axis of the second spring to maintain the second spring in guide.
- A drawback of this toe-piece of the ski binding consists in the fact that during use snow inserts between the joint and the ski, where it might get compacted and thus might be an obstacle to the correct functioning of the toe-piece of the ski binding.
- The aim of the present invention consists in at least limiting the above-mentioned drawback.
- The above aim is attained by a toe-piece of a ski binding for ski mountaineering, according to
claim 1. - The quantity of snow that inserts between the joint and the ski is advantageously smaller. In fact, in the prior art the snow was able to pass between the turns of the springs, while with the invention the first spring is closed by the first jaw and the first portion of joint. Further, the lateral walls that rise from the base flank both frontally and posteriorly the first jaw, the first portion of joint, the second portion of joint and the second jaw in such a measure as to at least limit the passage of snow. Further, the height of the lateral walls at least partially closes the gap between the lateral walls, on one side, and the first jaw, the first portion of joint, the second portion of joint and the second jaw, on the other side.

The blocking lever (6) is preferably rotatable in a revolute pair to the activating lever (3), so as to rotate with respect to the fourth axis of rotation (R4). The activating lever (3) can rotatably couple to the blocking lever (6) at a second end, opposite the first end, see for example
figure 2 . - The first spring (51) can be a compression spring.
- The second end of the first spring (51) is opposite the first end of the first spring (51).

- Still more preferably, the external walls (100) of the first portion of jaw (110), of the first portion of joint (41), of the second portion of joint (42) and of the second portion of jaw (120), which face in an opposite direction with respect to the tip of the ski (30) (see for example
figure 2 ), when the base (2) is fixed to the ski (30), form a continuous surface in order at least to limit the passage of snow. - According to a first embodiment, the toe-piece of the ski binding (1) comprises second elastic means (52) which comprise a second spring (52) interposed between the second jaw (12) and the second portion of joint (42). Further: the second portion of joint (42) is provided with a third spring seat (63) for receiving a first end of the second spring (52); the second jaw (12) is provided with a fourth spring seat (64) for receiving a second end of the second spring (52); the second jaw (12) and the second portion of joint (42) are telescopically coupled to one another, so as to allow a relative sliding between the second jaw (12) and the second portion of joint (42) when the activating lever (3) activates the joint (4), at least one from between the second jaw (12) and the second portion of joint (42) comprising a tubular telescopic coupling portion (see for example

- Figures from 1 to 15 illustrate the first embodiment. In particular,
figures 1-8 show a configuration ready to receive the ski boot: the first pin (21) and the second pin (22) are sufficiently moved away from one another in order to allow the tip of the ski boot (40) to insert between the pins and press on the activating lever (3): in turn, the activating lever (3), by means of the first prong (81), presses on the joint (4), leading to the consequent transition of the toe-piece of the ski binding to a descent configuration,figures 9-15 , in which the ski boot (40) is hooked to the first pin (21) and to the second pin (22). Starting from the descent configuration, as is known, the skier can activate the blocking lever (6) to block the activating lever (3) and walk uphill (the ascent configuration is not illustrated). - Instead,
figures 16-19 and20-23 show a second and third embodiment, respectively, in which the second elastic means (52) have not been used. In this case the second jaw (12) and the second portion of joint (42) are connected to one another to form a single body, see for examplefigure 23 . - The joint (4) preferably comprises a pin (7); further, the first portion of joint (41) and the second portion of joint (42) are coupled to one another by means of the pin (7).

- The pin (7) preferably has a cylindrical shape; further, the first pin seat (91) forms a first portion of cylindrical wall in order to realise a form coupling with the pin (7), see for example
figure 8 ; the second pin seat (92) forms a second portion of cylindrical wall in order to realise a form coupling with the pin (7). - The first embodiment illustrated in
figures 1-15 uses the pin (7). - In alternative,
figures 20-23 : the first portion of joint (41) comprises a third portion of cylindrical wall (93); the second portion of joint (42) comprises a fourth portion of cylindrical wall (94); the third portion of cylindrical wall (93) and the fourth portion of cylindrical wall (94) are directly coupled to one another realising a form coupling. - It is specified that also the third embodiment of
figures 20-23 might, alternatively, use the pin (7) according to what is indicated in the foregoing and with what is illustrated infigures 1-19 . - Likewise, the first embodiment illustrated in
figures 1-15 and the second embodiment illustrated infigures 16-19 might, alternatively, not use the pin (7) and use a direct coupling between the first portion of joint (41) and the second portion of joint (42), as explained in the foregoing with reference tofigures 20-23 and to the third portion of cylindrical wall (93) and the fourth portion of cylindrical wall (94). - It is understood that the above has been described by way of non-limiting example and that any technical-functional variants are considered to fall within the protective scope of the present technical solution, as claimed in the following.
