Title (EN) DOOR LATCH ASSEMBLY
(FR) ENSEMBLE VERROU DE PORTE
(KO) 도어 래치 어셈블리
Abstract:
(EN) The present invention relates to a door latch assembly including: a case (100) composed of left and right division members and having provision holes (101) formed at both side surfaces thereof, and having an opening part (103), which is formed at one side end part and has a cover (102) coupled thereto; a hub (200) rotatably provided in the provision holes (101); a locking member (300) for setting the locking of a door by controlling the rotation operation of the hub (200); a sliding member (400) elastically provided by a coil spring (401) so as to slide by the rotation of the hub (200); and a latch bolt (500) provided to enter and exit the opening part (103) for controlling the opening and closing of the door. The present invention further includes an operation rod (600) for sliding together with the sliding member (400) and a latch bolt (500) enabled to slide and rotate, thereby achieving purposes of stably opening and closing the door even with small force by improving the operability of the latch bolt when opening the door and, simultaneously, suppressing noise in the process of opening or closing the door.
(FR) La présente invention concerne un ensemble verrou de porte comprenant : un boîtier (100) composé d'éléments de séparation gauche et droit et pourvu de trous (101) formés au niveau de ses deux surfaces latérales, et comportant une partie d'ouverture (103) qui est formée au niveau d'une partie d'extrémité latérale et à laquelle est accouplé un élément de recouvrement (102); un moyeu (200) disposé rotatif dans les trous (101) ; un élément de verrouillage (300) pour procéder à la fermeture d'une porte par commande de l'opération de rotation du moyeu (200); un élément coulissant guidé élastiquement (400) par un ressort hélicoïdal (401) de manière à coulisser par la rotation du moyeu (200); et un pêne demi-tour (500) disposé de façon à entrer et sortir de la partie d'ouverture (103) pour commander l'ouverture et la fermeture de la porte. La présente invention comprend en outre une tige d'actionnement (600) pour coulisser conjointement avec l'élément coulissant (400) et un pêne demi-tour (500) conçu pour coulisser et tourner, ce qui permet d'ouvrir et de fermer la porte de manière stable, même sous l'action d'une force légère par amélioration de la capacité de fonctionnement du pêne demi-tour lors de l'ouverture de la porte et, simultanément, de supprimer le bruit dans le processus d'ouverture ou de fermeture de la porte.
(KO) 본 발명은 도어 래치 어셈블리에 관한 것으로서, 좌우 분할체로 구성되어 양 측면에 설치공(101)을 형성하고 일측 단부에는 커버(102)가 결합되는 개구부(103)를 형성한 케이스(100)와, 상기 설치공(101)에서 회전 가능케 설치한 허브(200)와, 상기 허브(200)의 회전 동작을 제어하여 도어의 잠금을 설정하는 록킹부재(300)와, 상기 허브(200)의 회전에 의해 슬라이딩 작동하도록 코일스프링(401)으로 탄설하는 슬라이딩부재(400)와, 상기 개구부(103)를 출입하도록 설치되어 도어의 여닫힘을 제어하는 래치볼트(500)를 포함하는 도어 래치 어셈블리에 있어서, 슬라이딩부재(400)와 함께 슬라이딩 작동하는 작동봉(600)과, 슬라이딩과 회전 작동이 가능케 한 래치볼트(500)를 포함하여 구성함으로써 도어 개방시 래치볼트의 작동성을 향상시켜 적은 힘으로도 도어의 개폐가 안정적으로 이루어지도록 함과 동시에 도어가 여닫히는 과정에서 소음 발생을 억제할 수 있게 한 목적을 달성할 수 있다.
