Abstract
Abstract Improved device for fixing equipment, in particular electrical apparatus, on supports such as switchboards of the kind in which the apparatus comprises a threaded socket passing through an orifice formed in the switchboard and held by means of a knurled knob supported against the front face of said switchboard with no need to take into consideration the thickness of the switchboard because the screwing down of the knurled knob causes the rotation of the socket and the upward movement of a clamping ring against the internal face of the switchboard until the final fixing is obtained.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
266 words
A device for mounting an apparatus to be fixed in an aperture of a panel, the device including in combination: a. a hollow base at the lower portion of which is provided a base plate for fixing the apparaTus, said base presenting towards the panel a hollow cylinder, said cylinder junction with the base an abutting surface being perpendicular to the axis of the cylinder, said base provided externally with at least one longitudinal groove parallel to the axis, b. an annular socket adapted to fit rotatively on the outward surface of said cylinder and to abut by its extremity on said abutting surface between the cylinder and the base, said socket being threaded externally and provided with a ring member to be screwed on the thread of the socket and to be blocked to the top thereof, said socket being removably attached on its top to an internal lip of the cylinder of said base by a snapping member, c. and a clamping ring acting as a nut, which has a surface adapted to meet inwardly the rear face of the panel, said clamping ring being screwed on said threaded part of the socket, said clamping ring presenting opposite the panel, at least a lug adapted to slide in the groove of said base; whereby, after assembling the parts of the device, through the aperture of the panel, by turning the ring member which is blocked on the annular socket, the clamping ring will move longitudinally and clamp the edge of the panel against the ring member oppositely positioned, without which the base could rotate.
Claim 2
Independent Claim
266 words
A device for mounting an apparatus to be fixed in an aperture of a panel, the device including in combination: a. a hollow base at the lower portion of which is provided a base plate for fixing the apparaTus, said base presenting towards the panel a hollow cylinder, said cylinder junction with the base an abutting surface being perpendicular to the axis of the cylinder, said base provided externally with at least one longitudinal groove parallel to the axis, b. an annular socket adapted to fit rotatively on the outward surface of said cylinder and to abut by its extremity on said abutting surface between the cylinder and the base, said socket being threaded externally and provided with a ring member to be screwed on the thread of the socket and to be blocked to the top thereof, said socket being removably attached on its top to an internal lip of the cylinder of said base by a snapping member, c. and a clamping ring acting as a nut, which has a surface adapted to meet inwardly the rear face of the panel, said clamping ring being screwed on said threaded part of the socket, said clamping ring presenting opposite the panel, at least a lug adapted to slide in the groove of said base; whereby, after assembling the parts of the device, through the aperture of the panel, by turning the ring member which is blocked on the annular socket, the clamping ring will move longitudinally and clamp the edge of the panel against the ring member oppositely positioned, without which the base could rotate.
Claim 3
Dependent Claim
84 words
A device according to claim 1, in which the base is provided with a cylindrical part which overlaps the said cylinder of the base, the overlapping part forming an annular groove to receive the lower portion of said socket, and the bottom of the groove constituting the said abutting surface for the extremity of said socket, said overlapping part having a cylindrical periphery with a groove for a sealing joint, whereby the clamping ring has an internal chamber to slide on said sealing joint.
Claim 4
Dependent Claim
32 words
A device according to claim 1, in which said snapping member is a ring, said ring having a plurality of vertical legs, each leg comprising a small hook turned towards the exterior.
Claim 5
Dependent Claim
32 words
A device according to claim 1 in which the top of said socket presents two shoulders in order that said snapping member and said ring member may be flush with said top.
