[0003] The anti-stress device of the present invention is particularly suitable for a wide range of applications, from children's toys to in-vehicle accessories and key chains. [Background technology]

[0004] There are finger-based anti-stress devices in the art. For example, some prior art anti-stress devices are configured to be held by two fingers of one hand and moved, for example rotationally, by pushing with the fingers of the other hand.

[0005] Disadvantageously, such known anti-stress devices are not suitable for use with one hand and require the user to have both hands free in order to use them.

[0006] These devices are intended to be used solely for anti-stress purposes, and no indication is provided as to how often they will be used. Summary of the Invention

[0007] There therefore appears to be a significant need to provide a finger anti-stress device that is able to overcome the drawbacks typical of the state of the art.

[0008] The present invention therefore aims to overcome the drawbacks of prior art finger anti-stress devices by providing a finger anti-stress device which can be used with one hand, is adaptable to a wide range of functions and is particularly suitable for providing an indication of its use.

[0009] This need is met by an anti-stress device as claimed in independent claim 1. The dependent claims describe preferred or advantageous embodiments of the invention which comprise further advantageous features. [Brief description of the drawings]

[0011] With reference to the aforementioned figures, a finger anti-stress device, and in particular an anti-stress device wearable on a finger, is generally designated by the reference numeral 1. For clarity and ease of explanation, in the remainder of this specification the finger-wearable anti-stress device will be referred to simply as the anti-stress device.

[0012] According to the invention, the anti-stress device 1 comprises a ring 3 and a body 10 .

[0013] The ring 3 extends along and around the axis of rotation Y and defines a finger seat 300 suitable for at least partially receiving a user's finger.

[0014] As used herein, the term "ring" refers, without limitation, to an object having a substantially annular body, which is preferably substantially symmetrical and has a central hollow, either a completely open cavity or a blind or partially blind cavity.

[0015] The body 10 is provided with a ring seat 23. Within the body 10, the ring 3 is rotatably engaged relative to the body 10 such that torque applied to the ring 3 by the user's finger allows free rotation of the body 10 relative to the ring 3 and about the axis of rotation Y.

[0016] Preferably, the ring seat 23 is a through cavity provided in the body 10 .

[0017] In one embodiment, the ring 3 is engaged to the ring seat 23 by a magnetic coupling.

[0018] The anti-stress device 1 further comprises a power supply device 90, such as a battery, and a rotation counter sensor 40 powered by the power supply device 90. The rotation counter sensor 40 is configured to rotate integrally with the body 10 or the ring 3 and count the number of complete relative rotations between the ring 3 and the body 10.

[0019] The term "count" is not intended to be limiting, but it is clear that it means that the rotation counter sensor 40 is configured to generate a complete rotation signal for every complete relative rotation between the ring 3 and the body 10.

[0020] The revolution counter sensor 40 preferably comprises an electronic unit (such as an electronic circuit or logic unit) arranged to receive said complete revolution signal generated by the revolution counter sensor 40 .

[0021] In one embodiment, said electronic unit is adapted to process the complete rotation signal to generate a certain rotation value increment which is preferably stored in a storage unit.

[0022] In a second embodiment, the electronic control unit is configured to process the complete rotation signal and convert it into a command to activate an indication system or an auxiliary notification system (e.g., auditory or visual) as described below with reference to preferred embodiments of the present invention.

[0023] That is, in this embodiment, the complete rotation signal is directly converted into a start command without numerically increasing the RPM value.

[0024] A power supply 90 is housed within the body 10 and / or on the ring 3 .

[0025] That is, when a user inserts a finger into finger sheet 300 and applies a rotational thrust force to anti-stress device 1 with the same finger inserted into finger sheet 300, main body 10 rotates around ring 3.

[0026] According to one embodiment, the power supply 90 comprises a battery housed within the main body 10, as shown, for example, in FIG. 1a.

[0027] According to one embodiment, the power supply device includes a system for converting mechanical power into electrical power. For example, this conversion system includes a dynamo arranged to convert the relative rotational movement between the ring 3 and the body 10 into electrical power. According to one embodiment, the conversion system is directly connected to power the revolution counter sensor 40. According to one variant, the conversion system is connected to a battery, whereby the generated electrical power recharges the battery.

[0028] It is clear to a person skilled in the art that, if the conversion system includes a dynamo, the conversion system, and therefore the power supply device, can be partly housed on the ring 3 and partly housed in the body. For example, the magnets of the dynamo can be housed on the ring 3 and the windings on the body, or vice versa. In other words, the conversion system makes it possible to obtain a self-powered or self-charging anti-stress device 1 thanks to the same rotational movement.

[0029] Referring to the embodiment shown in Figures 5 to 7, the ring 3 is preferably constructed from a cylindrical body.

[0030] In one embodiment, finger sheet 300 is preferably hollow through ring 3 .

[0031] In another embodiment, the finger sheet 300 is a blind cavity of the ring 3. That is, the finger sheet 300 of the ring 3 is a cavity that is closed on one side.

[0032] In a preferred embodiment, the revolution counter sensor 40 is contained within and integral with the body 10, as shown, for example, in FIGS.

[0033] In another embodiment, the revolution counter sensor 40 is located on the ring 3 and is integral with it.

[0034] In a preferred embodiment, the anti-stress device 1 comprises a counting lever 41 operatively connected to a revolution counter sensor 40 .

[0035] According to this embodiment, the ring 3 includes an actuation tooth 31 protruding outwardly therefrom, i.e. opposite to the finger seat 300, such that when a user exerts a torque on the ring 3 with his finger to manipulate the rotation of the body 10 around the ring 3, the actuation tooth 31 is suitable for triggering the counting lever 41 with each rotation, and the rotation counter sensor 40 is configured to increment the count of rotations with each activation of the counting lever 41.

[0036] In a particularly advantageous embodiment, the counting lever 41 is configured so as to be activated only when rotation about the axis of rotation Y takes place in one direction, but not in both directions.

[0037] With reference to the embodiment of FIG. 8, the counting lever 41 is preferably provided with an inclined surface 401 suitable for contacting the actuation tooth 31 during relative rotation between the body 10 and the ring 3 .

[0038] More preferably, the counting lever 41 is in elastic engagement with the revolution counter sensor 40, whereby the actuating tooth 31, when engaged with the inclined surface 401, actuates the counting lever 41 for each revolution by pushing the counting lever 41 to switch from a projected configuration to a pressed configuration. Moreover, this counting lever 41, by virtue of its elastic engagement with the revolution counter sensor 40, preferably returns to its projected configuration when the actuating tooth 31 is no longer in a position to activate the counting lever 41.

[0039] In a preferred embodiment, through the elastic engagement and shape of the counting lever 41, the counting is activated only in one direction of rotation.

[0040] In this preferred embodiment, referring to the example of FIG. 8, the counting lever 41 preferably includes an abutment surface 402 intersecting the inclined surface 401 .

[0041] The abutment surface 402 is a curved or linear surface suitable for abutting against the actuation tooth 31 .

[0042] In particular, when the counting lever 41 is in a protruding configuration, when a rotation of the body 10 around the ring 3 occurs in a first direction, the actuation tooth 31 is suitable to compress the inclined surface 401, press the lever and trigger a count of the revolution counter sensor 40. On the other hand, when a rotation of the body 10 around the ring 3 occurs in a second direction opposite to the first direction, the actuation tooth 31 is suitable to abut against the abutment surface 402 and does not allow a compression of the inclined surface 401.

[0043] In this embodiment, counting of rotations is only permitted in one direction, clockwise or counterclockwise, depending on how the counting lever 41 is positioned.

[0044] In another embodiment, the number of revolutions can be counted in both directions of rotation.

[0045] According to this embodiment of the invention, the rotation counter sensor 40 comprises an electronic encoder, preferably an angular encoder, suitable for detecting the relative rotation between the ring 3 and the body 10 .

[0046] Preferably, in such an embodiment, the ring 3 does not include an actuation tooth 31 .

[0047] In an advantageous variant embodiment, as shown for example in Figures 5 to 7, the ring 3 extends along and around the axis of rotation Y between an upper end 350 and a lower end 350' and has an upper enlarged portion 35 at the upper end 350 and a lower enlarged portion 35' at the lower end 350'.

[0048] Furthermore, in this variant embodiment, the ring 3 has a narrow central portion 36 between the upper and lower enlarged portions 35, 35'.

[0049] The upper and lower enlarged portions 35, 35' extend radially relative to the axis of rotation (Y) to a greater thickness than the narrow central portion 36.

[0050] Preferably, as seen in the example embodiment of FIG. 7, the actuation teeth 31 project outwardly from a side wall 360 of the narrow central portion 36 .

[0051] Also preferably, the teeth 31 are made integral with the ring 3, i.e. the teeth 31 are integrated with the ring 3 and obtained as one piece.

[0052] In one embodiment of the present invention, and with reference to the example embodiment of Figures 5 and 6, upper and lower enlarged portions 35, 35' each include a respective annular relief 370, 370'.

[0053] In this embodiment, as shown by way of example in Fig. 3 and better illustrated in the enlarged view of Fig. 4, the ring seat 23 is delimited by an upper seat edge 230 and a lower seat edge 230' that are suitable for abutting respective annular reliefs 370, 370' of the ring 3 in order to lock the ring 3 against axial sliding in the ring seat 23 along the axis of rotation Y.

[0054] According to a preferred variant embodiment, as can also be seen in the example embodiment of FIG. 2, the anti-stress device comprises a display system 5, preferably a display, operatively connected to the revolution counter sensor 40 and suitable for digitally displaying the number of revolutions counted by the revolution counter sensor 40.

[0055] In a preferred embodiment, the body 10 further comprises hook means 26 suitable for hooking one or more keys.

[0056] Advantageously, this embodiment allows the anti-stress device 1 to be used simultaneously as a key chain and as a toy. Advantageously, in fact, the body 10 is rotatable about the ring 3 even when a key is hooked on the hook means 26.

[0057] In a preferred embodiment, as can be seen in the example embodiment of Fig. 1a, the anti-stress device 1 comprises an auxiliary display system 6, preferably an LED strip, operatively connected to the revolutions counter sensor 40. The auxiliary display system 6 is configured to provide a graphical representation of the user's stress level as a function of the number of revolutions counted by the revolutions counter sensor 40.

[0058] In a preferred embodiment, the anti-stress device 1 comprises both a display system 5 and an auxiliary display system 6 .

[0059] Preferably, the display system 5 and the auxiliary display system 6 are arranged on the same side of the anti-stress device 1, i.e. the user sees both display systems from one perspective.

[0060] Instead, referring to the example embodiment shown in Figures 1a and 1b, the display system 5 and the auxiliary display system 6 are arranged on opposite sides of the anti-stress device 1. That is, the user sees the display system 5 from a first perspective and the auxiliary display system 6 from a second perspective. In other words, to switch from seeing the display system 5 to seeing the auxiliary display system 6, the user has to turn the anti-stress device 1 over.

[0061] The auxiliary display system 6 is configured to display a first coloring 8 when the number of revolutions counted by the revolution counter sensor 40 is less than a certain predetermined threshold, and to display a second coloring 9 when the number of revolutions counted by the revolution counter sensor 40 is greater than the predetermined threshold.

[0062] Preferably, further referring to FIG. 1a, the auxiliary display system 6 is configured to display the first coloring 8, the second coloring 9 and the third coloring 9′ depending on the number of revolutions counted by the revolution counter sensor 4.

[0063] Additionally, the revolution counter sensor 40 is preferably configured to automatically reset, preferably every 24 hours.

[0064] Alternatively or additionally, the revolution counter sensor 40 is configured to be manually reset at the discretion of a user.

[0065] In the case where the revolution counter sensor 40 is configured to be automatically reset, the auxiliary display system 6 is, for example, preferably a color bar configured to light up in response to the revolution number signal detected by the revolution counter sensor 40, e.g., to show green, yellow and red, each color indicating a certain stress level. For example, when the number of revolutions in a day exceeds an upper threshold, the color bar lights up in response to said number of revolutions detected by the revolution counter sensor 40 and shows red, indicating a high stress level. Conversely, when the number of revolutions in a day does not reach a lower threshold, the color bar lights up in response to said number of revolutions detected by the revolution counter sensor 40 and shows green, indicating a low stress level.

[0066] When the number of revolutions per day is between the lower and upper thresholds, the bar is illuminated in response to said number of revolutions detected by the revolution counter sensor 40, preferably displaying the color yellow, indicating an intermediate stress level.

[0067] In one embodiment, the body 10 extends to surround the ring 3. In other words, the entire circumference of the ring 3 is at least partially surrounded by the body 10.

[0068] In other words, the side wall 360 of the ring 3 always faces the body 10 at least partially along its periphery.

[0069] In one embodiment, the ring 3 remains coupled to the body 10 at all times. Preferably, the ring 3 does not separate from the body 10 during rotation, i.e., the ring 3 remains coupled to the body 10 even during rotation.

[0070] Advantageously, this variant avoids the loss of components of the anti-stress device while preventing possible damage due to the ring separating from the body during rotation.

[0071] In the preferred embodiment, the body 10 comprises a shell 2 .

[0072] In one embodiment, the shell 2 includes a printed circuit board 4 operably connected to a revolution counter sensor 40 .

[0073] In an advantageous variant, referring to the exemplary embodiment shown in Figures 1a and 1b in the assembled state and in Figures 9a and 9b in the individual piece state, the shell 2 consists of a first shell part 21 and a second shell part 22 assembled to one another.

[0074] In this variant, the ring seat 23 is preferably provided partly in the first shell part 21 and partly in the second shell part 22. In other words, the ring 3 engaged in the ring seat 23 is partly engaged in the first shell part 21 and the second shell part 22.

[0075] Preferably, the first shell portion 21 and the second shell portion 22 are attached to each other by adhesive or interlocking.

[0076] In an advantageous embodiment, the shell 2 and the ring 3 are made entirely of hard plastic.

[0077] Preferably, and referring to the example of Figures 3 and 4, the shell 2 includes an outer wall 20 that defines an inner cavity 200 in which the printed circuit board 4 is housed.

[0078] More preferably, the outer wall 20 of the shell 2 includes an inner shell surface 210 having one or more locking projections 250 that restrain the printed circuit board 4 within the inner cavity 200, thereby locking the printed circuit board 4 within the inner cavity 200 even while the body 10 is rotating about the ring 3. In other words, these locking projections 250 hold or fix the circuit board 4 in the same position during rotation of the body 10 about the ring 3.

[0079] In a configuration in which the revolution counter sensor 40 is configured to be reset, the printed circuit board 4 comprises a reset command and the body 2 is provided with an auxiliary opening 290 suitable for making this reset command accessible from the printed circuit board 4.

[0080] In a preferred embodiment, the shell 2 completely surrounds the ring 3 within the ring seat 23 .

[0081] 1a and 1b, in a preferred embodiment, the shell 2 includes an elongated portion 270 that projects laterally relative to the ring seat 23. That is, the ring seat 23 is disposed on the opposite side of the body 10 relative to the elongated portion 270.

[0082] Advantageously, this preferred embodiment allows the user to effectively rotate the body 10 relative to the ring 3, and also acts as a mass, creating a flywheel effect to facilitate rotation without the need for application of high torque.

[0083] Preferably, the ring 3 is located at one end of the body 10. In other words, preferably, the ring 3 is located away from the center of the body 10.

[0084] That is to say, while defining the centre of gravity of the anti-stress device 1, this centre of gravity is preferably not located on the axis of rotation Y. In other words, the ring 3 is preferably offset from the centre of gravity of the anti-stress device 1.

[0085] Advantageously, this allows the anti-stress device to be conveniently operated with one hand and allows less torque to be applied to the ring to keep the body rotating, which also increases the flywheel effect making the device easier to rotate.

[0086] Preferably, furthermore, if the anti-stress device 1 is adapted to also function as a key chain, the hook means 26 protrudes from the body 10 at the elongated portion 270 of the body 2 .

[0087] More preferably, the hook means 26 is integral with the shell 2 .

[0088] This arrangement further increases the flywheel effect, which is greatly accentuated by the presence of the key depending from the hook means 26.

[0089] Preferably, there is a gap between the ring 3 and the ring seat 23 .

[0090] More preferably, the gap is at least partially filled with a lubricant to facilitate relative rotation between the ring 3 and the body 10 .

[0091] Advantageously, therefore, relative rotation between the body 10 and the ring 3 is permitted without the need for intermediate bearings. It will be clear to a person skilled in the art that intermediate bearings can be provided to allow relative rotation between the parts without departing from the scope of protection of the invention.

[0092] In a preferred embodiment, the upper and lower enlarged portions 35, 35' of the ring 3 include a curved surface 30 that is seamlessly connected to the outer wall 20 of the shell 2.

[0093] Advantageously, this shape, in addition to giving the product an aesthetically pleasing appearance, also provides greater ergonomics and allows for more practical use.

[0094] Preferably, the ring also has a smooth inner surface without any roughness, so that the finger may be inserted into the finger seat 300 without causing discomfort to the user.

[0095] Preferably, the shell 2 is covered with a printed film featuring a design or bearing a decorative motif.

[0096] In a preferred embodiment, the anti-stress device 1 further comprises optical signalling means, such as an LED or laser emitter, mounted on the ring 3 or on the body 10 and suitable for emitting light while the body 10 rotates relative to the ring 3.

[0097] That is, in a preferred embodiment, the anti-stress device 1 is provided with additional lights which generate a light game intermittently, continuously or with color changes depending on the user's rotation of the main body 10 relative to the ring 3.

[0098] In a modified embodiment, the anti-stress device 1 comprises additional sensors, mounted on the ring 3 or on the body 10, suitable for detecting vital parameters of the individual using the device, such as respiratory rate, heart rate, blood saturation, blood pressure, etc.

[0099] For example, the additional sensor may include a heart rate monitor, and / or a pressure sensor, and / or a sensor configured to detect the saturation level.

[0100] Innovatively, the finger-worn anti-stress device according to the invention makes it possible to overcome all the drawbacks of prior art anti-stress devices.

[0101] Advantageously, the anti-stress device according to the invention is of simple design, containing a limited number of parts.

[0102] Moreover, advantageously, the anti-stress device according to the invention can be used with only one hand, thus leaving the user's other hand free to perform other activities.

[0103] According to a further advantage, the anti-stress device according to the invention allows for tracking of the use of the anti-stress device through the use of a revolution counter sensor.

[0104] Further, advantageously, the count produced by the revolution counter sensor is effectively displayed to the user by a digital display, e.g., by a numeric display, and / or a graphical display, e.g., by an LED strip or color bar.

[0105] Advantageously, the anti-stress device is further adapted for a wide range of uses, such as a key chain, through the hook means.

[0106] Advantageously, furthermore, the anti-stress device is ergonomic and convenient to use, thanks to the continuous connecting shape of the ring and the body.

[0107] It is obvious that those skilled in the art can modify or replace the above-described embodiments of the anti-stress device with functionally equivalent elements to meet specific needs. Such modifications are also included in the scope of protection defined by the claims. Moreover, each modification described as belonging to a possible embodiment can be implemented independently of the other modifications described. [Explanation of symbols]
