Description

SIMPLIFIED SADDLE HINGE OF A SADDLE-RIDE VEHICLEDESCRIPTIONTECHNICAL FIELD

[0001] The present invention relates to a hinge for a saddle mounted on a saddle-ride vehicle, such as a motorcycle, scooter or the like.STATE OF THE ART

[0002] Motor vehicles such as scooters comprise a saddle that is configured to open to provide access to an under-saddle storage compartment, used to store a helmet or other items. The under-saddle compartment is formed in a central body of the motorcycle and the saddle is mounted at the compartment by means of a saddle hinge which allows the saddle to open and close, giving access to the under-saddle compartment.

[0003] The saddle hinges used for this purpose have been developed to make it easier for the user to keep the saddle open in a stable position, in order to be able to remove or load items in or from the under-saddle compartment, while preventing the saddle from closing involuntarily.

[0004] WO2018180034 discloses a saddle hinge which envisages the saddle opening in two distinct angular positions. In each of the two positions the saddle maintains a stable position. In a first position the saddle is partially open, remaining at least partly overlapping the under-saddle compartment. In a second position the saddle is completely open, beyond the vertical direction, leaving the under-saddle compartment completely accessible, without the saddle causing an impediment from above.

[0005] The saddle hinge of WO2018180034 employs a hinge mechanism comprising a plurality of pivotable and mutually slidingly interconnected elements which result in poor reliability over time. In particular, it has been found that with prolonged use over time the hinge mechanism tends to at least partially jam. This aspect is due to the fact that the components thereof tend to loosen and, therefore, both the opening and closing movement of the saddle is less fluid. When closing the saddle, this drawback can lead to a loss of alignment with the lock and therefore a difficult closing of the saddle itself.SUMMARY

[0006] It is therefore the object of the present invention to provide a saddle hinge for a saddle-ride vehicle which, while providing the same functions, is constructionally simpler and more reliable.

[0007] The aforesaid objects are now achieved by a saddle hinge of a saddle-ride vehicle. In particular, the saddle-ride vehicle comprises an under-saddle body, which defines a storage compartment, and a saddle. The saddle is pivotally mounted to the under-saddle body and is configured to selectively switch between an open configuration, which allows access to the storage compartment, and a closed configuration which closes access to the storage compartment.

[0008] In detail, the saddle hinge comprises a first hinge portion configured to be connected to the under-saddle body and a second hinge portion configured to be connected to the saddle. The first and second hinge portions are pivotally connected to each other by means of a pin which defines a respective hinge axis, which extends longitudinally along the pin.

[0009] An elastic element is also provided between the first hinge portion and the second hinge portion. The elastic element, in particular at least one spring, is configured to facilitate opening the saddle, i.e., to develop an elastic force which tends to facilitate the relative rotation of the second hinge portion with respect to the first hinge portion around the hinge axis in a saddle opening direction.

[0010] The saddle hinge further comprises a first abutment, formed on the first and / or second hinge portion, configured to come into contact with the elastic element, defining a first stable opening position of the saddle, the first opening position is defined by a first opening angle. The opening angle refers to the angle formed between two parts of the respective hinges, which is essentially equivalent to the angle formed between the saddle and the top plane of the under-saddle body. The saddle hinge further comprises a second abutment formed on the first and / or second hinge portion, configured to define a second stable opening position of the saddle having a second opening angle greater than the first opening angle.

[0011] Thereby, the saddle hinge according to the present invention is structurallysimplified compared with the solutions of the known art, not requiring additional interconnected elements interposed between the first and second hinge portion, to define distinct stable opening positions. The saddle hinge, according to the present invention, uses simple abutment portions formed on the hinge portion(s), which act in combination with the elastic element to define one of the two stable opening positions of the saddle. The saddle hinge is therefore constructively simple and economical to produce, as well as functional.

[0012] Advantageously, the first abutment is formed on the first hinge portion and comprises a contrast wall which defines a shoulder on which the elastic element stably rests when the first opening angle is reached, keeping the saddle stable in the first opening position. Thereby, the first abutment is formed simply by shaping the first hinge portion without adding constraining elements arranged between the first and second portions.

[0013] Advantageously, the second abutment is formed on the first and second hinge portion and comprises respective shoulders which come into contact with each other when the second opening angle is reached. Also in this case, the second abutment is formed by specifically shaping the first and second portions juxtaposing each other to define a second stable position.

[0014] In particular, the first opening angle al is less than a 90° angle, in particular between 70° and 80°.

[0015] Preferably, the second opening angle (a2) is between 75° and 110°, in particular between 80° and 100°.

[0016] Advantageously, the elastic element is a torsion spring fitted on the pin and comprising a contrast portion in contact with the second hinge portion which develops a torque which facilitates the relative rotation of the second hinge portion with respect to the first hinge portion in the opening direction of the saddle.

[0017] Advantageously, the first hinge portion comprises a first bottom wall adapted to be fixed to the under-saddle body and in which the abutment wall extends from the first bottom wall defining an “L” shape, or a folded shape.

[0018] In particular, the abutment wall extends inclined from the first bottom wall, defining an abutment angle.

[0019] Advantageously, the second hinge portion comprises a second bottom wall adapted to be fixed to the saddle, and in which a contrast wall is provided which extends from the second bottom wall defining an “L” shape, or a folded shape. The contrast wall extends inclined from the second bottom wall defining a contrast angle, in which the contrast portion of the torsion spring rests in contrast on the contrast wall.

[0020] Preferably, the first hinge portion and the second hinge portion are partially overlapping at respective holes formed at opposite ends from each other, said holes being shaped to accommodate the pin and to pivotally connect the first and second hinge portions together.DESCRIPTION OF THE DRAWINGS

[0022] The following description of one or more embodiments of the invention refers to the attached drawings. The same numerical references in the drawings identify equal orsimilar elements. The object of the invention is defined by the appended claims. The technical details, structures or features of the solutions described below can be combined with each other in any manner.

[0023] Figure 1 shows a saddle-ride vehicle 100, in particular in the form of a scooter. As is known, the scooter 100 comprises at least a front steered wheel 103 controlled by means of a handlebar 107 and a rear driving wheel 104. In Figure 1 and following, in particular, a three-wheeled motorcycle is depicted, provided with two front wheels 102, mounted by means of a four-bar linkage which allows the vehicle to roll.

[0024] The motorcycle comprises an under-saddle body 101 in which a storage compartment 105 is formed. A saddle 102 is pivotally connected to the under-saddle body 101 at which a saddle hinge 10 according to the present invention is mounted. In particular, the saddle hinge 10 comprises a first hinge portion 1 shaped to be fixed to the under-saddle body 101, and a second hinge portion 2 shaped to be fixed to the saddle 102, in a known manner. The first hinge portion 1 comprises fixing holes 1' arranged to make the connection to the under-saddle body 101. Similarly, the second hinge portion 2 comprises fixing holes 2' to achieve the fixing with the saddle 102.

[0025] The first hinge portion 1 and the second hinge portion 2 are pivotally hinged to one another around a pin 3, which defines a hinge axis AA. Thereby, a relative rotation of the second hinge portion 2, the one which supports the saddle 102, is possible with respect to the first hinge portion 1, fixed to the body 101 of the motorcycle, both in an opening direction T1 and in a closing direction T2, opposite each other (Fig. l).

[0026] Furthermore, the saddle hinge 10 comprises at least one elastic element 4, arranged between the first hinge portion 1 and the second hinge portion 2. The elastic element 4 generates an elastic force between the first and second hinge portion 1,2 which promotes and accompanies the opening of the saddle 102 in the direction Tl.

[0027] The saddle hinge 10 further comprises a first abutment 5, formed on the first and / or second hinge portion, cooperating with the elastic element 4. The first abutment 5 is shaped to restingly support the elastic element 4, defining a first stable position Al for opening the saddle 102 (Fig.5 A). The first stable position Al of the saddle 102 is defined by a first opening angle al (Fig.4A), measured relatively between the first hinge portion 1 and the second hinge portion 2.

[0028] The saddle hinge 10 further comprises a second abutment 7, 8, formed on the first and / or second hinge portion, and angularly offset with respect to the first abutment 5. The second abutment 7, 8 defines a second stable opening position A2 of the saddle 102 having a second opening angle a2, greater than the first opening angle al.

[0029] Constructionally, in a preferred embodiment, the first abutment 5 is formed on the first hinge portion 1 and comprises a contrast wall 5' on which the elastic element 4 abuts when the first opening angle al is reached, maintaining the saddle 102 in the first stable opening position Al.

[0030] Preferably, the second abutment is formed in combination on the first and second hinge portions and comprises respective shoulders 7, 8 which come into contact with each other when the second opening angle a2 is reached, maintaining the saddle 102 in the second stable opening position A2.

[0031] In detail, in the first stable opening position Al, the first opening angle al is less than a 90° angle, in particular between 70° and 80°. In this case, the saddle 102, as shown in Figure 5 A, is distanced from the handlebar 107 and takes a position at least partially overlapping the upper part of the storage compartment 105. The first opening position Al of the saddle is, for example, used to store or remove from the compartment 105 items which are not particularly bulky. The static position of the saddle 102, however, allows unimpeded movements inside the storage compartment 105, without having to support the saddle 102.

[0032] Instead, in the second stable opening position A2, the second opening angle a2 is greater than the first opening angle al, and substantially between 75° and 110°, in particular, between 80° and 100°. The second opening angle a2 is advantageously greater than 90°, causing the saddle 102 to have an opening beyond the vertical direction, which keeps the storage compartment 105 completely free from above. The saddle 102 is substantially closer to the handlebar 107.

[0033] Constructionally, as shown in Figure 2 or also in Figures 3, 3a, 3b, 3c the elastic element 4 is a torsion spring fitted on the pin 3.

[0034] The torsion spring 4 comprises a contrast portion 4' shaped to contrastingly abut with the second hinge portion 2. The contrast portion 4' imparts the elastic force of thetorsion spring to the second hinge portion 2, generating a torque which facilitates the relative rotation of the second hinge portion 2 with respect to the first hinge portion 1 in the opening direction of the saddle 102.

[0035] Constructionally, the torsion spring 4 also comprises a fixing portion 4” with the first hinge portion 1, which blocks the relative rotation thereof around the pin 3. The fixing portion 4” is represented by two filaments on opposite ends of the spring which are stuck on the first hinge portion 1, so as to keep the torsion spring 4 fixed, avoiding rotation about the pin 3 (Fig.3). The contrast portion 4' is instead a curved portion formed in the centreline of the torsion spring which extends cantilevered with respect to the pin 3. The latter contrasts with the second hinge portion 2, on which it unloads the elastic force.

[0036] When operating the hinge 10, the contrast portion 4' is in contact with the second hinge portion 2 until reaching the first opening angle al (Figures 3B, 4 and 4A) and is spaced from the second hinge portion 2 (Figure 4B) in the rotation beyond the first opening angle al, to reach the second stable portion A2 with the second opening angle a2.

[0037] In particular, the first hinge portion 1 comprises a first bottom wall la adapted to be fixed to the under-saddle body 101. The contrast wall 5' extends from the first back wall la, defining an “L” shape. The contrast wall 5' extends inclined from the back wall la, defining an abutment angle bl (Fig.4A). In particular, the contrast wall 5' is formed in one piece in the first hinge portion 1, as described in detail below.

[0038] Similarly, the second hinge portion 2 comprises a second bottom wall 2a adapted to be fixed to the saddle 102. The second hinge portion 2 includes a contrast wall 6 which extends from the second back wall 2a defining an “L” shape.

[0039] In detail, the contrast wall 6 extends inclined from the second bottom wall 2a, defining a contrast angle b2. The contrast portion 4' of the torsion spring 4 contrastingly rests on the contrast wall 6. The contrast wall 6 determines the preload of the torsion spring 4, preloading the contrast portion 4' when the saddle hinge 10 is in the closing configuration C (Fig.4). As the saddle 102 is opened, the contrast portion 4' pushes against the contrast wall 6, accompanying the opening of the saddle 102 in the opening direction Tl.

[0040] In other words, the torsion spring 4 acts on the second hinge 2 by means of the contrast portion 4'. The contrast portion 4' is a cantilevered winding of the torsion spring projecting with respect to the axis A- A, which comes into contact with the second hinge portion, in particular with the contrast wall 6. The latter is shaped so as to preload the spring and give it an elastic torque which tends to open the saddle 102 once a lock 108 of the under-saddle compartment 105 is opened (Fig. l). Thereby, the opening of the saddle 102 is accompanied in the opening direction T1 thanks to the spring force developed by the torsion spring 4, making the opening simpler. The elastic force of the torsion spring 4 substantially counteracts the weight of the saddle 102 in the opening phase.

[0041] When the saddle hinge 10 reaches the first stable opening position Al, the abutment wall 5' and the contrast wall 6 are aligned with respect to a plane P. In this position the contrast portion 4' is unloaded and the saddle 102 maintains the first equilibrium position Al since the centre of gravity of the saddle 102 is to the right of the axis A-A. By applying a further push beyond such a first stable position Al, the saddle 102 rotates further until it reaches the second stable position A2 (Fig.4B). In such a position, as mentioned above, the contrast portion 4' of the spring 4 no longer has a direct contact with the contrast wall 6.

[0042] Constructionally, as better shown in Figures 4 and 4A, the first hinge portion comprises a cradle wall Id which extends from the bottom wall la and connects to the abutment wall 5'. The shape of the first hinge portion 1 therefore defines the housing for the pin 3, in the cradle wall Id and the abutment wall 5' which extends from the latter in one piece. As better shown in Figure 3c, the abutment wall 5' extends such as to at least partially surround the pin 3 and the torsion spring 4. Thereby, the axis of the pin 3 lies on a plane P2 below a plane Pl on which the bottom wall la of the first hinge portion 1 lies. Such a shape with the pin 3 in an offset position with respect to the bottom wall la of the first hinge portion 1 makes the saddle hinge more versatile and adaptable to different types of saddle-ride vehicles.

[0043] In other constructional aspects, the first hinge portion 1 and the second hinge portion 2 partially overlap each other at the respective holes lb, 2b formed on opposite ends; the holes lb, 2b are shaped to accommodate the pin 3 and to pivotally connect the first 1 and the second 2 hinge portions together.

[0044] In detail, as shown in Figure 2, the first hinge portion 1 comprises the first bottom wall la from which side walls 1c extend, opposing each other. The first holes lb for the pin 3 are formed on the side walls 1c.

[0045] Instead, in a preferred embodiment, the second hinge portion 2 is “L”-shaped and also includes side walls 2c which extend on opposite sides with respect to the second bottom wall 2a. The holes 2b for the pin 3 are formed on the side walls 2c. When the second hinge portion 2 is coupled to the first hinge portion 1, the holes lb, 2b are coaxial with each other and accommodate the pin 3.

[0046] In particular, as better shown in Figure 4B, the second abutment is formed by two shoulders 7 and 8 formed respectively on the first hinge portion 1 and on the second hinge portion 2. As better shown in Figure 3A, in the first stable position Al the shoulders 7 and 8 are spaced apart from each other, thus allowing a further relative rotation between the hinge portions 1, 2. When, rotating about the pin, the shoulder 8 reaches the second angle a2, it comes to abut against the shoulder 7 of the first hinge portion, effectively blocking the rotation and defining the second stable position A2 of the saddle 102, visible in Figures 4B and 5B.

[0047] The opening operation of the saddle 102 by means of the hinge 10 according to the present invention allows two possible positions of the saddle 102 to be obtained. A first opening position in which the saddle 102 is open by the first angle al, maintaining a first stable position Al (Fig.4). The first position Al is advantageous because the saddle 102 can also be opened with the steering handlebar 107 in a rotated configuration with active steering lock. In this position the handlebar 107 takes a position rotated by approximately 45° with respect to a position with the handlebar straight. In this case, in the first opening position Al the saddle 102 does not interfere with the handlebar 107, still allowing an opening of the saddle 102 and access to the storage compartment 105. Starting from this position, the saddle 102 can be further rotated in the opening direction Tl. The further rotation brings the saddle 102 to a second stable position A2, see Figure 5B. In the second position A2, total access to the storage compartment 105 is configured, with the saddle 102 preferably rotated beyond the vertical direction.
