Definitions

  • the present invention relates to a door damper for preventing impact and noise generated when a door for a furniture article or a sink is rapidly opened and closed and the door is impacted on a doorframe.
  • a door is mounted through a spring hinge on a sink or a furniture article such as a clothes chest and a bookcase.
  • a spring hinge on a sink or a furniture article such as a clothes chest and a bookcase.
  • the door is impacted on a doorframe and large impact is applied to the door, and noise is generated due to the impact. In the worst case, the door may be damaged.
  • FIG. 1 In the conventional door damper, however, when the door mounted through a spring hinge is suddenly closed, the door is bounced from a bumper 13 and noise is also generated, since an oil path through first and second check valves 21 and 22 is narrow, a pressure in an oil chamber 3 is excessively increased. A housing surrounding the oil chamber 3 is bent to an outside due to the increase in the pressure. Therefore, a fine gap is generated between a housing body 16 and an oil seal 17 for preventing oil leakage so that the oil is leaked. Since the door is closed by the spring hinge, a return spring 15 having small elastic force has to be used in the spring hinge. In this case, there is a problem that the door is slowly returned.

  • An edge side of the second check valve 200 is bent to the outer circumference in a moment. That is, as shown in B of FIG. 10, the second check valve 200 plugs up the AA portion.
  • the oil is moved through the BB portion, thereby absorbing the impact.
  • the impact from the door can be facilely absorbed. And also, since the oil path is widely formed, the door can be easily returned to its position even through the return spring has a small elastic force.

Abstract

Cette invention concerne un amortisseur de porte destiné à empêcher les chocs et les bruits produits par une porte de meuble ou d'évier que l'on ouvre et referme rapidement et qui heurte contre son cadre. Un joint à huile disposé dans un logement forme une chambre à huile et est traversé en son centre par une tige de piston. Outre un guide de cylindre et un premier et un second clapets anti-retour montés à une extrémité de la tige et piston et régulant le chemin de l'huile, on trouve dans le corps logement un ressort amortissant les heurts de la porte. Une bague de guidage est disposée dans la partie ouverte du corps de logement, cependant qu'une coiffe d'amortisseur et un amortisseur sont montés sur l'autre extrémité de la tige de piston. Cette invention permet d'absorber facilement les chocs de la porte. Comme le trajet de l'huile est largement dimensionné, la porte revient facilement à sa position de départ alors même que le ressort ne possède qu'une faible force élastique.
