Patent

CA 2331459

The buffer device (10) has a body (11) which can be fitted in a rail (4), a damping element (12) for cushioning, and a retaining spring (13) for retaining a running mechanism (6) which is guided in the rail (4) and is provided for carrying and guiding slidable wing elements (2). The at least approximately U-profile-shaped body (11) of the buffer device (10), which body is punched and bent from a metal element, has a first and a second wing (14; 18), which wings are connected to each other by a central piece (20) whose tongue-shaped extension forms the retaining spring (13) serving to retain the running mechanism (6) The end pieces (17, 19, 26; 17*, 19*) of the wings (14; 18) are configured in such a manner that they are suitable for retaining the damping element (12). The buffer device (10) can be manufactured cost-effectively from a single metal plate and can be completed by a damping element (12). Since the retaining spring (13) is a component part of the body (11) of the buffer device 910), the device is highly stable.

L'invention concerne un dispositif tampon (10) présentant un corps (11) qui peut être monté dans un rail (4), un élément d'amortissement (12) pour amortir un mécanisme de roulement (6) qui est guidé dans le rail (4) et sert à supporter et à guider des éléments de battant (2) coulissants, ainsi qu'un ressort de maintien (13) servant à maintenir ledit mécanisme de roulement. Le corps (11) du dispositif tampon (10), qui est cintré et découpé dans un élément métallique et présente au moins approximativement la forme d'un profilé en U, comprend un premier et un deuxième bras (14 ; 18) qui sont reliés par un élément central (20) dont le prolongement en forme de languette forme le ressort de maintien (13) servant à maintenir ledit mécanisme de roulement. Les parties terminales (17, 19, 26; 17*, 19*) des bras (14; 18) sont conçues de sorte qu'elles puissent maintenir l'élément d'amortissement (12). Ce dispositif (10) peut être produit de manière économique à partir d'une seule plaque métallique et complété par un élément d'amortissement (12). Le dispositif tampon (10) présente une stabilité élevée car le ressort de maintien (13) fait partie intégrante du corps (11) du dispositif tampon.
