Description

[0001] The present patent application for industrial invention relates to a binding system of a snowboard boot onto a snowboard.

[0002] Specifically, the present patent application relates to the field of snowboards and in particular to the binding system that are used to attach a snowboard boot to a snowboard.

[0003] As it is well known, conventional binding systems for snowboard boots comprise a binding that is attached to the snowboard and comprises a base structure attached to the snowboard, a spoiler against which a rear portion of the boot leg is suitable for abutting, a toe strap suitable for embracing the toe of a hull of a snowboard boot, and an ankle strap suitable for embracing the portion of the snowboard boot that connects the boot leg and the hull of the snowboard boot.

[0004] Both the toe strap and the ankle strap comprise a padded strap and toothed tabs and ratchets for adjusting the pressure exerted by the strap against the snowboard boot.

[0005] Such a conventional type of binding systems is inconvenient for a user because the user must operate the ratchets after each ride to disengage the toothed tabs in such a way that the user can use a chairlift or a cable car or the like, and must re-engage the toothed tabs before using the snowboard to go down a slope.

[0006] Over time, fast-binding systems have been developed that allow the user to avoid using the aforementioned straps consisting of toothed tab and ratchet.

[0007] Such new binding systems involve the use of complex linkages and coupling systems that must be operated manually by the user.

[0008] However, such binding systems are not satisfactory because the user must operate the levers manually during the attachment and detachment operations. Obviously, such manual operations are inconvenient and time-consuming for the user. Therefore, by way of example, such binding systems do not allow the user to attach the snowboard boot to the snowboard while standing and pushing the snowboard boot onto the board. In addition, such systems are expensive and extremely complicated to make.

[0009] AU2020201580A1, DE19602667C1, US2004232658A1 and KR20000060267 describe conventional binding systems of a snowboard boot onto a snowboard that are extremely complex and do not allow a snowboard boot to be attached to a snowboard in an easy, smooth and quick way.

[0010] The purpose of the present invention is to devise a new binding system for attaching a snowboard boot onto a snowboard that allows the user to quickly attach and detach the snowboard boot to / from the snowboard.

[0011] Another purpose of the present invention is to devise a binding system for a snowboard boot onto a snowboard that allows the user to attach the snowboard boot to the snowboard by standing and simply pushing the snowboard boot onto the snowboard.

[0012] These purposes are achieved in accordance with the invention with the features listed in the attached independent claim 1.

[0025] Specifically, by way of example, said adjustment means comprise toothed plastic tabs and ratchets.

[0026] The ends (81) of the ankle strap (8) are connected to the connecting portions (73) of the support (7) by means of a linkage assembly (K). Each linkage assembly (K) comprises: an insert (9) in the shape of "infinity" or "eight" comprising a first eyelet (91) with a hole (910) and a second eyelet (92) with a hole (920); and a connecting pin (A) that is threaded into the hole (910) of the first eyelet (91) of the insert (9), into a hole (811) of the end (81) of the ankle strap (8) and is attached to a first fastening element (731) (indicated with a circle) of the connecting portion (73) of the support (7).

[0027] The pin (1) is threaded into the hole (920) of the second eyelet (92) and is engaged to a second fastening element (732) (indicated with a circle) of the connecting portion (73) of the support (7).

[0028] By way of example, the connecting pin (A) and the first fastening element (731) can be configured in such a way as to provide a push-button type coupling.

[0029] Similarly, the pin (1) and the second fastening element (732) can be configured in such a way as to implement a push-button type coupling.

[0030] The pin (1) comprises a cylindrical body (10) that passes through the hole (920) of the second eyelet (92) of the insert (9) and is attached to the second fastening element (732) and an enlarged head (11) that mates with the second eyelet (92) of the insert (9).

[0031] Again with reference to Figs. 1, 1A, 2 and 3, the second portion (G2) of the binding system (100) comprises a base structure (2) suitable for being attached to the snowboard (T).

[0032] The base structure (2) comprises a plate (21) suitable for contacting against the snowboard (T). The base plate (21) comprises a front portion (211), a rear portion (212) and through holes (213) suitable for accommodating screws for attaching the base structure (2) to the snowboard (T). The plate (21) also comprises two side edges (214) parallel to each other.

[0033] The base structure (2) comprises two opposing side edges (22) that rise from the side edges (214) of the base structure (2).

[0034] Each side edge (22) comprises a projecting rear portion (221) that protrudes beyond the rear portion (212) of the plate (21).

[0035] In addition, each side edge (22) comprises an inner face (22a) facing the other side edge (22) and an outer face (22b) opposite the inner face (22a).

[0036] Referring to Figs. 1 and 4, the base structure (2) also comprises two engagement seats (20) formed on the two side edges (22), two end-stop seats (25) formed on the two side edges (22), and two centering seats (27) formed on the two side edges (22).

[0037] Specifically, each engagement seat (20) consists of a notch made in an upper edge of the projecting rear portion (221) of the side edge (22).

[0038] Each end-stop seat (25) consists of a notch made in the upper edge of the projecting rear portion (221) of the side edge (22), in a position behind the engagement seat (20).

[0039] The engagement seat (20) and the end-stop seat (25) essentially define a jagged profile on the upper edge of the projecting rear portion (221).

[0040] Each centering seat (27) consists of a low-relief indentation that is formed on the inner face (22a) of the side edge (22) and ends on the upper edge of the side edge (22) at a position in front of the engagement seat (20). The centering seat (27) is suitable for receiving the second eyelet (92) of a respective insert (9) of the first portion (G1) of the binding system (100).

[0041] However, the function of the centering seat (27) will become clearer with reference to the following description.

[0042] Referring to Figs. 1, 1A, 2, 3, and 4, the second portion (G2) of the binding system (100) further comprises a front locking device (6) connected to the base structure (2) and configured in such a way as to anteriorly lock the toe portion of the hull (S2) of the snowboard boot (S).

[0043] Specifically, the front locking device (6) comprises a toe strap (60) configured in such a way to embrace a toe portion of the hull (S2) of the snowboard boot (S).

[0044] The toe strap (60) is schematically shown in the attached figures, but is a conventional toe strap (60) comprising a padded strap and adjustment means configured in such a way as to adjust the pressure exerted by the strap on the snowboard boot (S).

[0045] Specifically, by way of example, said adjustment means comprise toothed plastic tabs and ratchets.

[0046] The toe strap (60) comprises two ends (61) connected to the side edges (22) of the base structure (2). Specifically, the toe strap (60) is connected to front ends of the side edges (22). A low-relief indentation (29) suitable for accommodating an end (61) of the toe strap (60) is provided on the inner face (22a) of each side edge (22) and at the front end. Each end (61) of the toe strap (60) is connected to the respective side edge (22) by means of connecting means, such as snap fasteners.

[0047] The second portion (G2) further comprises a rear spoiler (3).

[0048] The rear spoiler (3) comprises a concave central support (3b) against which a rear part of the boot leg (S1) of the snowboard boot (S) is suitable for resting, and two side wings (3a) that extend anteriorly from the central support (3b) and are essentially parallel to each other.

[0049] The rear spoiler (3) comprises two attachment seats (30), each one being formed on one of the two side wings (3a).

[0050] Specifically, the attachment seats (30) are concave seats formed on a front edge (30a) of the side wings (3a) of the spoiler (3). The attachment seats (30) are suitable for engaging the pins (1) of the first portion (G1) and in particular the cylindrical body (10) of the pins (1) of the first portion (G1).

[0051] The spoiler (3) is pivoted to the base structure (2) around a pivoting axis (X) to move from a closed position (shown in Figs. 1A and 6), wherein the attachment seats (30) of the spoiler (3) face toward the base structure (2) to hold the pins (1), to an open position (shown in Fig. 5), wherein the attachment seats (30) of the spoiler (3) do not hold the pins (1).

[0052] With reference to Figs. 5 and 6, when the spoiler (3) is in the closed position, the spoiler (3) is arranged in a e substantially orthogonal position to the base structure (2) (see Fig. 6), whereas when the spoiler (3) is in the open position, the spoiler (3) is tipped behind the base structure (2) in a substantially parallel position to the base structure (2) (see Fig. 5).

[0053] With reference to Figs. 1 and 1A, the spoiler (3) is pivoted around the pivoting axis (X) by means of pivoting means (P1) consisting of pins threaded into holes (f3) drilled in the side wings (3a) of the spoiler (3) and into holes (f2) drilled in the rear protruding portions (221) of the side edges (22) of the base structure (2).

[0054] The spoiler (3) further comprises two stop surfaces (31), both of which are formed on the front edges (30a) of the two side wings (3a), each one terminating in a respective attachment seat (30). The stop surfaces (31) are suitable for being intercepted by the pins (1) when the snowboard boot (S) is pushed toward the base structure (2), to rotate the spoiler (3) from the open position to the closed position in such a way that the attachment seats (30) engage the pins (1).

[0055] Again with reference to Figs. 1, 1A, 2, 3 and 4, the second portion (G2) of the binding system (100) further comprises a lever (4) shaped like a fork and comprising an actuation arm (45) suitable for being grabbed by a user and two lateral arms (46).

[0056] The two lateral arms (46) comprise first sections (461) that diverge from each other and are inclined to each other by an angle comprised between 110° and 130° and second end sections (462) that are substantially parallel to each other.

[0057] The lever (4) is pivoted to the spoiler (3) around a pivoting axis (Z) parallel to the pivoting axis (X) to rotate between a locking position, wherein it locks the spoiler (3), and an unlocking position, wherein it releases the spoiler (3).

[0058] Specifically, the lever (4) is pivoted around the axis of rotation (Z) by means of rotation means (P2) consisting of pins threaded into holes (q3) drilled on the side wings (3a) of the spoiler (3) and into holes (q4) drilled on the lateral arms (46) of the lever (4).

[0059] The lever (4) has two retaining teeth (40), each one being made on one of the two lateral arms (46), suitable for engaging the engagement seats (20) of the base structure (2) when the spoiler (3) rotates from the open position toward the closed position in such a way to lock the spoiler (3) in the closed position.

[0060] Specifically, the retaining teeth (40) are formed on the ends of the second sections (462) of the lateral arms (46) and serve basically as hooks to anchor to the engagement seats (20) of the base structure (2).

[0061] Moreover, the retaining teeth (40) are suitable for engaging the end-stop seats (25) when the spoiler (3) rotates from the closed position to the open position to stop the travel of the spoiler (3) in the open position.

[0062] The second portion (G2) also comprises a spring (5) that constantly pushes the lever (4) toward its locking position.

[0063] Specifically, the spring (5) is connected on one side to the spoiler (3) and on the other side to the lever (4) By way of example, the spring (5) is an annular elastic spring that is attached to partitions (38, 48) of the central support (3b) of spoiler (3) and of the actuation arm (45) of the lever (4) located in through openings made on the central support (3b) of the spoiler (3) and on the actuation arm (45) of the lever (4), respectively.

[0064] With reference to Figs. 7-7C, 8-8C, 9-9Cbelow is a description of how to attach a boot (S) to a snowboard (T) by means of the binding system (100) according to the invention.

[0065] With reference to Figs. 7, 8 and 9, reference is made to an initial condition, wherein the spoiler (3) of the second portion (G2) of the binding system (100) is in open position. As shown in Figs. 7 and 8, in such a condition, the retaining teeth (40) of the lever (4) are engaged with the end-stop seats (25) to prevent the spoiler (3) from positioning itself beyond its open position.

[0066] Therefore, starting from such a condition, the snowboard boot (S) is brought closer to the base structure (2) by inserting the toe of the snowboard boot (S) into the toe strap (60).

[0067] With reference to Figs. 7A, 8A, and 9A, while the snowboard boot (S) is approaching the base structure, the two pins (1) intercept the stop surfaces (31) of the spoiler (3), resulting in the rotation of the spoiler (3) from the open position to the closed position.

[0068] More precisely, the stop surfaces (31) of the spoiler (3) are intercepted by the cylindrical body (10) of the two pins (1).

[0069] During the rotation of the spoiler (3), the attachment seats (30) of the spoiler (3) engage the pin (1). Specifically, the attachment seats (30) of the spoiler (3) engage the cylindrical bodies (10) of the two pins (1), as shown in Fig. 9B.

[0070] With reference to Fig. 8B, it is worth pointing out that in addition, during the approaching travel of the snowboard boot (S) to the base structure (2), the second eyelet (92) of the insert (9) is inserted into the centering seat (27), which therefore acts as a guide during the approaching travel of the snowboard boot (S) to the base structure (2).

[0071] With reference to Figs. 7B and 8B, during its rotation, the spoiler (3) drags along the spring (5) and then the lever (4). When the spoiler (3) reaches its closed position, the lever (4) engages the base structure (2) by means of the retaining teeth (40) that anchor to the engagement seats (20).

[0072] In such a situation, therefore, the spoiler (3) is locked in its closed position and the snowboard boot (S) is stably attached to the snowboard. With particular reference to Fig. 8B, it should be noted that the centering seats (27) are sized so that the second eyelets (92) of the inserts (9) are perfectly accommodated in the centering seats (27) without clearance. In such a way, the second eyelets (92) are coupled with the walls that define the centering seats (27), assisting the lever (4) in keeping the spoiler (3) locked in the closed position.

[0073] With reference to Figs. 7C, 8C and 9C, in order to unlock the spoiler (3) and thus detach the snowboard boot (S), it will be necessary to move the lever (4) from the locked position to the unlocked position, overcoming the resisting force exerted by the spring (5) and then lift the snowboard boot (S).

[0074] Following the above description, therefore, the advantages of the present invention now appear obvious.

[0075] Firstly, the binding system (100) according to the invention allows the user to attach and detach the boot from / to the snowboard quickly.

[0076] In addition, the binding system (100) according to the invention allows the user to attach the boot to the snowboard while standing by simply pushing the boot toward the snowboard.

[0077] Finally, the binding system (100) according to the invention is inexpensive and easy to make.

[0078] Although it is always shown in the attached figures that the first portion (G1) comprises the ankle strap (C) whereon the pins (1) are attached, in an alternative embodiment of the invention said ankle strap (C) may be absent and the pins (1) may be directly attached to the snowboard boot (S).

[0079] Additionally, according to an alternative embodiment of the invention, the first portion (G1) may comprise only one pin (1), e.g. protruding from the back of the boot leg (S1) of the snowboard boot (S) suitable for cooperating with only one stop surface (31) and with only one attachment seat (30) of the spoiler (3).

[0080] In addition, the lever (4) may comprise only one central retaining tooth (40) capable of engaging only one engagement seat (20) and only one end-stop seat (25), both of which being made on a rear part of the base structure (2).

[0081] Numerous variations and modifications of detail may be made to the present embodiment of the invention, within the reach of an expert of the field, anyhow falling within the scope of the invention as expressed by the appended claims.
