With the spherical side, the transmission element 36 is in contact with the joint socket 3 or can be brought into operative connection with the joint socket 31 via it.

Abstract

La présente invention concerne un ensemble de maintien (1) pour le montage suspendu d'un objet (2), en particulier une caméra de sécurité, sur un plafond (3) ou un mur (15), comprenant au moins un dispositif de maintien (4) et au moins une broche de retenue (5) qui est reliée à l'objet (2) et s'étend le long d'un axe longitudinal (LA), le dispositif de maintien (4) comprend au moins une partie de fixation (6), pour la fixation du dispositif de maintien (4) au plafond (3) ou au mur (15), et une partie de réception (10), qui est opposée à la partie de fixation (6) et présente un axe de réception (AA), pour recevoir au moins partiellement la broche de retenue (5), l'objet (2) pouvant être monté sur la partie de réception (10) de manière à être suspendu par la broche de retenue (5). L'ensemble de maintien (1) est caractérisé en particulier en ce que la broche de retenue (5) reçue est fixée dans la partie de réception (10), au moins contre un déplacement axial, au moyen d'un mécanisme d'encliquetage (14). L'invention concerne en outre un procédé de montage suspendu d'un objet (2), en particulier une caméra de sécurité, sur un plafond (3) ou un mur (15) au moyen d'un ensemble de maintien (1), une broche de retenue (5) reliée à l'objet (2) étant introduite dans une partie de réception (10) du dispositif de maintien (4). Le procédé est caractérisé en particulier en ce que la broche de retenue (5) est fixée dans la partie de réception (10), au moins contre un déplacement axial, par un mécanisme d'encliquetage (14).
