Title
(EN) QUICK CONNECT COUPLING
(FR) ACCOUPLEMENT A CONNEXION RAPIDE
Abstract
(EN)
A coupling comprising a male and female half (11, 12) that are coupled together in axial alignment. A keying portion (13) is provided at one end of the male half (11) which has at least one keying element (14) with a bearing surface (20). The female half (12) has an opening (17) located on one side with recesses (18) therein shaped for location of the keying element (14). The opening (17) allows the keying portion (14) to engage the opening (17) in a direction that is transverse to the aligned axis. The recess (18) has abutment surfaces (21) against which the bearing surfaces (20) locate when the keying portion (14) is engaged within the recess (18). The bearing (21) and abutment (20) surfaces prevent separation of the coupling when placed under tension along the aligned axis. The invention provides a simplified means for connection of the coupling while at the same time allowing relative rotation between the male and female halves (11, 12).
(FR)
L'accouplement comprend une moitié mâle et une moitié femelle (11, 12) qui sont couplées selon un alignement axial. Une portion de clavetage (13) est prévue à une extrémité de la moitié mâle (11) qui possède au moins un élément de clavetage (14) avec une surface d'appui (20). La moitié femelle (12) possède une ouverture (17) située sur un côté et présentant des évidements (18) recevant l'élément de clavetage (140. L'ouverture (17) permet à la partie de clavetage (14) d'entrer dans l'ouverture (17) dans un sens transversal à l'axe d'alignement des deux moitiés. L'évidement (18) possède des surfaces de butée (21) contre lesquelles s'appuient les surfaces (20) lorsque l'élément de clavetage (14) est engagé dans l'évidement (18). Les surfaces d'appui (21) et de butée (20) empêchent la séparation de l'accouplement lorsqu'il est placé sous tension le long de l'axe d'alignement. L'invention constitue un moyen simplifié de connexion des éléments d'accouplement tout en permettant une rotation relative entre la partie mâle (11) et la partie femelle (12).
