[0011] The aim of this innovation is to provide a flexible and extendible bracelet that is easy to wear .

[0012] Problem Solution

[0013] According to this invention, a flexible and extendible bracelet , as set forth in claim 1 , is provided . Preferred embodiments of this innovation are then defined in the attached dependent claims .

[0014] Brief Description of the Drawings

[0015] The invention wi ll now be described with reference to the attached drawings , illustrating a non-limiting embodiment thereof , in which :

[0016] • Figure 1 illustrates a side exploded view of a flexible and extendible bracelet produced according to the precepts of this invention;

[0017] • Figure 2 illustrates a side view of a flexible and extendible bracelet produced according to the precepts of this invention;

[0018] • Figure 3 illustrates an exploded perspective view of a flexible and extendible bracelet produced according to the precepts of this invention;

[0019] • Figure 4 illustrates a perspective view of a flexible and extendible bracelet produced according to the precepts of this invention; and

[0020] • Figures 5 and 6 illustrate the flexible and extendible bracelet arranged in a closed position .

[0021] Preferred Embodiment

[0022] Figures 1 to 6 illustrate a flexible and extendible bracelet as a whole, denoted, as a whole , with the reference number 1 .

[0023] The bracelet 1 comprises : a flexible tubular element 2 consisting of a ( known) metal braid consisting of links 3 that can be moved relative to one another to al low the metal braid to be extended axially; a first tubular end sleeve 4 connected (with prior art techniques from the goldsmith field) to a first end 2 -a of the flexible tubular element 2 ; a second tubular end sleeve 5 connected (with prior art techniques from the goldsmith field) to a second end 2 -b of the flexible tubular element 2 opposite the first end 2 -a ; a helical spring 7 ( Figures 1 and 3 ) housed within the flexible tubular element 2 ( Figures 2 and 4 ) provided with a first end 7-a connected (with prior art techniques from the goldsmith field) to a first pin 10 carried inside the first tubular end sleeve 4 and a second end 7-b connected (with prior art techniques from the goldsmith field) to a second pin 11 carried inside the second tubular end sleeve 5 .

[0024] In the preferred embodiment , the first tubular end sleeve 4 has an inner threaded portion 13 configured to accommodate - in use - a threaded portion 15 of the first pin 10 . Similarly, the second tubular end sleeve 5 has an inner threaded portion 16 configured to accommodate - in use - a threaded portion 17 of the second pin 11 .

[0025] The threaded portions 13 , 15 and 16 , 17 might not be included and the pins 10 , 11 might be firmly attached to the sleeves 5 and 4 using di f ferent techniques , for example welding .

[0026] More speci fically, each pin 10 , 11 ( the pins have the same structure ) comprises : a cylindrical central portion 20 provided with the thread 15 , 17 ; a cylindrical appendage 22 coaxial to the central cylindrical portion 20 and extending towards the flexible tubular element 2 , an end portion of the cylindrical appendage 22 is f irmly connected to the first / second end 2- a, 2-b ( Figure 2 ) of the helical spring 7 ; a mushroom-shaped appendage 22 coaxial to the central cylindrical portion 20 and extending outwards from the tubular sleeve when the pin 10 , 11 is mounted on the respective tubular sleeve 4 , 5 .

[0027] In use , to fasten the bracelet 1 , the flexible tubular element 2 is arranged in such a way that it has a circular track ( Figures 5 and 6 ) and the pins 10 , 11 are connected to each other with a clasp 30 of a known type ( schematically indicated by a spherical body) which engages the mushroomshaped appendages 22 which are each provided with a stem and a wider part .

[0028] Before performing this operation, one or more decorative elements 33 ( in the example , shaped like a heart but they can have any shape ) , each with a circular opening engaged by the flexible tubular element , can be mounted on the flexible tubular element . In this way, the decorative elements 33 slide freely along the flexible tubular element . To put the bracelet on, the wearer simply applies a force to widen the flexible tubular element 2 , which increases in diameter due to the s liding of the links 3 one in relation to the other, adopting a deformed position . The action of the spring 7 returns the bracelet to its initial not deformed position .
