Description

System for adjusting the length of a bracelet or strap}

The present invention relates generally to a portable product comprising a bracelet or a case in which a bracelet or a string in the form of strands of two bracelets or straps is fixed.

The prior art discloses that a wrist watch is secured to a user's wrist via a leather or rubber strap or metal bracelet and the strap or bracelet is formed of two wear straps. Thus, the field of view comprises two pairs of horns facing each other diagonally. Next, two strings formed on the strap or bracelet are secured to the watch case by two pairs of protrusions. The two strings formed on the strap or bracelet are secured to each other by a clasp that attaches the wrist watch to the user's wrist.

According to the problem with the strap or bracelet of the above type, the length of the strap or bracelet is not freely adjusted. In fact, metal bracelets consist of links that are removed or added to adjust the length of the bracelet. Since the links have a fixed size, it is not always possible to make precise adjustments to the wrist dimensions. In connection with a leather or rubber strap, holes may be drilled in the leather or rubber strap so that a togue slips into the hole. If the user wants to avoid weakening the strap, the number of holes is limited. In fact, if too many holes are formed, the space formed between each hole becomes smaller and as a result the strap becomes relatively more fragile. If the space between two holes breaks, the holes become unavailable. There is no means for finely adjusting the length of the bracelet or strap, which results in inconvenience for the user.

According to another problem with the bracelets and straps, the length of the bracelets and straps cannot be adjusted according to the surrounding environment, in particular the temperature. The physiognomy of the human body can change depending on the environment in which the person is located. One of the environmental factors that affect the shape of the human body is temperature. Thus, the limbs of a person tend to contract when feeling cold and conversely, a limb of a person tends to swell when feeling hot. As a result, the wearer's wrist contracts or expands with temperature, ie the diameter of the wrist changes with temperature. Although leather or rubber straps can be tightened or loosened, metal bracelets can't be tightened or loosened. Therefore, the size of the bracelet can not be adjusted according to the temperature.

Thus, a user wearing a bracelet that is fitted to the user's wrist at ambient temperature, the bracelet becomes too long when the user feels cold and too short when feeling hot.

The present invention relates to a portable product that overcomes the problems of the prior art by providing a portable product in which the length of the bracelet or strap can be finely adjusted and adapts to changes in human shape with temperature.

Therefore, the present invention includes a case in which a bracelet or a strap, which is configured in the form of two straps of a bracelet or a strap, is fixed to the case, and two straps of the bracelet or strap are fixed to the case by two pairs of protrusions. It relates to a product, characterized in that at least one of the two pairs of protrusions is slidably and movably mounted relative to the case so that the length of the bracelet or strap can be adjusted.

According to a first advantage of the portable product according to the invention, the length of the bracelet can be simply changed. In fact, when the straps of the bracelet or strap can slide about the case, the user can change the length of the bracelet or strap without removing the portable product from the user's wrist.

Advantageous embodiments of the portable product form the subject matter of the dependent claims 2 to 15.

According to a first advantage of the embodiments, the wear strap of the bracelet or strap may be adjusted according to temperature. The portable product includes a control unit for controlling the sliding movement of the wear strap relative to the portable product. According to the measured temperature, the temperature sensor controls the adjustment of the bracelet or strap, and when the temperature increases with respect to the reference temperature, the bracelet or strap is increased and the temperature is decreased with respect to the reference temperature. Control the strap to be reduced.

Another advantage is the flexibility of the system. In fact, the adjustment system is an automatic system that is controlled according to temperature, but the adjustment function can be designed to be controlled by the user. In this case, the adjustment system is used to finely adjust the size of the bracelet or strap.

The present invention relates to a method for adjusting a bracelet or strap of a portable product, comprising the following steps,

Measuring the temperature,

Comparing the measured temperature with an upper threshold temperature and a lower threshold temperature,

Increasing the length of the bracelet or strap if the measured temperature is above the upper threshold temperature or decreasing the length of the bracelet or strap if the measured temperature is below the lower threshold temperature.

According to a feature of the invention, the bracelet or strap returns to the initial position when the measured temperature falls below the upper threshold temperature or rises above the lower threshold temperature, and when the measured temperature reaches the reference temperature, the bracelet or strap Returns to the initial position.

Features and advantages of the portable product are clearly understood in the following description of embodiments of the invention, which are provided as non-limiting examples and are shown in the accompanying drawings.

4, 5 and 6 schematically show a second variant of two embodiments of a portable product according to the invention.
7a-7c are schematic partial views of a second embodiment of a portable article of the invention arranged in different positions;

In the following description, all parts of a portable product known to those skilled in the art will be described in a simplified manner.

1 schematically shows a partial view of a portable product 1 according to the invention. The portable product 1 may be a watch or other device worn on the wrist, such as a heart rate monitor, a pedometer. The portable product 1 comprises a case 2 containing the components of the watch. The portable product 1 is secured to the user's wrist by a bracelet or strap formed of two strands 3. The wear straps 3 are fixed to the case 2 by protrusions 4 and are connected to each other by a clasp in the form of a tong or an unfolding buckle. The bracelet or strap consists of one wear strap 3, which is fixed to the case 2 by the respective ends of the wear strap, and the bracelet or strap is flexible.

The wear strap 3 can be made of steel, rubber or leather, for example. If the wear strap 3 is made of steel, the foldable buckle fastener is used and the bracelet is adjusted by adding or removing links from the wear strap 3. If the wear strap 3 is made of leather or rubber, adjustment is effected by holes formed in one of the wear straps 3.

In this case, the bracelet cannot be optimally adjusted to the user's wrist. To solve this problem, the present invention proposes the following method.

In the first embodiment, the protrusions 4 are slidably mounted in the case 2. Thus, the case 2 has orifices 9, and the orifices are dimensioned so that the protrusions 4 can be inserted and slid by the orifices. The protrusions 4 have a longitudinal element shape of parallelogram. Each protrusion 4 comprises means for securing the bracelet or wear strap 3 to the protrusion 4. Each projection 4 also comprises a tooth 8 at the end of the projection located in the case 2. By means of the length of the tooth 8 it is possible, for example, to adjust the desired dimensions of approximately 5 mm. Of course, the manufacturer can determine the adjustment dimension without being limited to the above dimensions.

When the gear 7 is set to rotate in the positive direction about the longitudinal axis, the gear 7 moves the protrusion 4 by the teeth 8 so that the protrusion ( 4) moves inside the case (2). On the contrary, when the gear 7 is set to rotate in the negative direction about the longitudinal axis, the protrusion 4 is moved by the teeth 8 so that the protrusion 4 is moved to the case ( 2) Move outside. The protrusion 4 preferably has stop means for limiting the movement of the protrusion 4 so that the gear 7 always works together with the tooth 8. For example, stop means for forming protrusions arranged at the ends of the protrusions may be considered.

Each gear 7 is actuated by an electric motor 6 via a transmission shaft 10. The portable product 1 also includes a control unit 5 for controlling the motor 6. The control unit 5 can send signals to the motors 6 in order to control the direction of rotation of the motor 7 and thus the gears 7.

In order to allow the user to adjust the size of the bracelet or strap of the portable product 1 to the size of the wrist of the user, the portable product 1 is interface means accessible from the outside by the user, as shown in FIG. (61). According to the embodiment of FIG. 1, the interface means comprises two pushbuttons 62, 63, by means of a first pushbutton 62 the protrusion 4 moving towards the interior of the case 2. By the second pushbutton 63, the protrusion 4 may move toward the outside of the case 2. The pushbuttons 62 and 63 are connected to the control unit 5 by a wire. Thus, when one of the pushbuttons 62, 63 is pressed, an electrical signal is transmitted to the control unit 5 and then activates the motor 6 of the projection 4.

According to a second embodiment of the invention, the bracelet can adapt to temperature to follow the change in size of the user's wrist with temperature. For this purpose, the control unit 5 comprises at least one temperature sensor, which can be configured in piezo or other form.

Thus, the temperature sensor is used to measure the temperature value transmitted to the control unit 5. Next, the control unit 5 controls the movement of the protrusion 4 in accordance with a predetermined temperature program and temperature data.

According to the first principle of operation, the control program embedded in the control unit 5 uses levels. The operation principle shown in Figs. 7A, 7B and 7C is simple and does not use a large amount of energy. To this end, the program forms at least three different steps to control the change in bracelet length. The first level, named TempCons, is the reference temperature. The second level, called TempMin, is the temperature at which wrist size decreases because tissue contracts in response to the cold. The third level is the temperature at which the wrist size increases because it is called TempMax and tissue expands in response to heat. For example, the tempcon level may be set to a value of 20 °, tempmin is set to a value of 10 °, and tempmax may be set to a value of 30 °.

Thus, at the temperature of the tempcon, the portable product 1 is arranged in the normal position shown in Fig. 7b. Thus, the protrusions 4 are arranged in a slightly protruding state such that the protrusions 4 move toward or opposite the case.

As the temperature increases, the control unit 5 adjusts the bracelet or wear strap 3 at the moment when it is detected by the temperature sensor that the temperature has reached a Tempmax value. Next, the protrusion 4 to which the bracelet or the strap 3 is fixed moves in a direction moving toward the outside of the case 2 as shown in FIG. 7B. Thus, the length of the bracelet is increased according to a predetermined amount of change.

In fact, it is estimated that the circumferential length of the wrist varies by 5 mm between the state where the user's wrist is contracted and the wrist is inflated. In other words, the circumference of the wrist varies by 2.5mm between the temperature of the tempcon and the temperature of the tempmax. The change is then the same between the temperature of the tempcon and the temperature of the tempmin. If the change is made by moving the two wear straps 3, the movement of each wear strap 3 is 1.25 mm. Of course, in this case only one wear strap 3 can be exercised, in which case the wear strap 3 should be able to move over a defined total amplitude.

Conversely, the control unit 5 adjusts the wear strap 3 at the moment when a temperature lower than tempermin is sensed by the temperature sensor when the temperature decreases. Next, the protrusions 4 to which the wear lines 3 are fixed are set to move in a direction moving toward the inside of the case 2 as shown in FIG. 7A.

There can be two cases regarding the transition between the tempmax temperature and the tempmin temperature.

According to the first case, the bracelet is considered to return to its original shape when the temperature sensed by the sensor falls within the temperature interval between Tempmin and Tempmax where the Tempmin and Tempmax temperatures are excluded. Thus, the control unit 5 activates the protrusion so that the protrusion 4 returns to its original position when the temperature drops below the tempmax or rises above the temp min.

In the second case, when the measured temperature reaches the tempcon value, the projection returns to the initial position of Fig. 7b. Thus, if the temperature is greater than the tempmax temperature, the protrusions 4 will only return to their original position when the temperature drops and reaches the threshold tempcon temperature. Similarly, if the temperature is less than the tempin temperature, the protrusion 4 will only return to the initial position when the temperature increases to reach the tempcon temperature. This mode of operation is very effective and consumes less energy because small temperature changes due to a change in position, such as moving from a sun-exposed location to the shade, do not affect the size change of the bracelet or wear strap 3. Proved to be Of course, the intermediate thresholds can be incorporated so that the bracelet size change is more granular.

According to the second principle of operation, the bracelet size is continuously adjusted. For this purpose, a value chart is stored in the portable product 1. The chart includes data regarding changes in bracelet size with temperature. Therefore, the bracelet size according to the temperature can be continuously adjusted by the numerical chart. Of course, the chart containing data on the change in bracelet size with temperature can be adjusted to have a relatively larger or smaller number of adjustment positions without being fixed.

Obviously, the ability to adjust the bracelet size to the size of the user's wrist over temperature is an independent feature. Thus, the function can be added to the function of finely adjusting the bracelet size according to the user's request. The portable product 1 may only include the function of adjusting the bracelet size according to the temperature.

According to a first variant of the two embodiments shown in FIG. 3 and according to the invention, the protrusions 4 fixed to the same wear strap 3 are integral with one another. As a result, the protrusions 4 fixed to the same wear line 3 form a U-shaped portion 41. The protrusions 4 securing the same wear strap 3 can always be kept in the same position with respect to each other by the U-shaped portion 41. The U-shaped portion prevents one protrusion from moving more than the other protrusion, prevents interference in alignment and prevents damage. A tooth 8, which works in conjunction with the gear 7, is located on each branch which forms a U-shaped portion 41 and is parallel.

According to a second variant of the two embodiments shown in FIGS. 4, 5 and 6 and according to the invention, the protrusions 4 securing the wear strap 3 form a U-shaped portion 42. The base portion of the U-shaped portion 42 includes a protruding element 44 such that the U-shaped portion 42 has a turning fork shape. The protruding element 44 has a pin shape extending toward the outside of the case 2 as shown in FIG. 5 or toward the inside of the case 2 as shown in FIGS. 4 and 6. Have Thus, the protruding element 44 supports the teeth 8.

According to a first optional configuration of the second variant, the projecting element 44 has two teeth 8 which work together with the gear 7 and the motor 6.

According to a second optional configuration of the second variant, the projecting element 44 has one tooth 8 which works with the gear 7 and the motor 6. Thus, one motor is provided for driving the pair of protrusions 4. According to this optional configuration, the number of motors 6 constituted in the case 2 is reduced, thus reducing power consumption and reducing the space occupied by the system.

Various modifications and / or improvements and / or combinations may be provided for the above embodiments of the present invention without departing from the scope of the invention as defined by the appended claims.

The portable product 1 may comprise two temperature sensors, the temperature used for adjusting the bracelet length being the average temperature measured by the two temperature sensors.
