Abstract
A fastening device (10) for securing a recessed casing in a cavity in a surface, comprises a guide (11) along which runs a slider (12) with a front engaging end (29). The slider (12) has unidirectional coupling means (19, 20) which engage with the guide (11). The slider (12) is also provided, towards the front end (29), with a cam surface (28) acting on the guide (11) in slots (21, 22) to increase the distance of the front end (29) of the slider (12) from the guide (11) when it is made to slide along the guide by manual shifting means (15). In this way, the front end (29) is brought into contact with the surface of the cavity and the slider (12) engages with the guide (11) by means of the unidirectional coupling means (19, 20).
Claims12
A fastening device for securing a recessed fixture in a cavity in a surface, comprising an elongate guide on said fixture disposed to extend substantially parallel to the axis of the cavity, a slider separate from and manually slidable in opposite directions on said guide in a path extending in the longitudinal direction of the guide and having a front end movable toward and away from said guide and an adjacent wall of the cavity, the slider having unidirectional coupling means engagable with said guide to couple it to the guide and having thereon, adjacent said front end thereof, a cam surface acting upon the guide to increase the distance of the front end of the slider from the guide when the slider is made to slide along the guide towards the surface containing said cavity, in order to bring said front end into fastening contact with said adjacent wall of the cavity, and to engage the guide with the unidirectional coupling means.
