An adjustable roof drain for flat and low pitch roofs includes a basin portion and a telescoping basin extension portion. A compression gasket provides a seal between the basin portion and the telescoping basin extension portions of the roof drain. The shape of the compression gasket causes it to be pushed inwardly when compressed so that it seals against the telescoping extension portion to both seal the extension portion and lock it at a selected height.

A drainage device is provided. The drainage device includes a drainage head having at least one head portion having an internal collection space and provided with at least one through recovery passage, and an attachment sleeve at least partially deformable. The attachment sleeve can be secured to the drainage head and capable of being inserted inside the flow pipe. The drainage device further includes a compression washer attached on the attachment sleeve and a central screw. The central screw can be movable in relation to the drainage head and threadably engaged with the compression washer to obtain, under the effect of a rotation of the central screw relative to the drainage head, an axial movement of the compression washer on the side of the drainage head and an outward radial deformation of the attachment sleeve.

A drainage device for a construction, e.g., a roof of a building or a terrace, for discharging rainwater, is provided. The drainage device includes a drainage head supported on the construction around a flow channel and defining a recovery space communicating with the outside and with the flow channel; and a mounting element having a support or attachment element capable of being engaged inside the discharge channel and abutting against the peripheral wall of the discharge channel. The device further includes a biasing element which connects the drainage head and the support or attachment element and is capable of acting on the support or attachment element so as to keep the drainage head supported on the outer surface of the construction.

The invention relates to a sealing ring including, axially, a main portion (2) and a secondary portion (3), connected by a weakened intermediate portion (4) which can be broken under an axial force applied between the main portion and the secondary portion, the main portion (2) including an annular sealing sleeve (5) and a projecting outer shoulder (6) arranged at the end of the annular sealing sleeve (5), opposite the breakable portion (4), and the secondary portion (3) including a projecting inner shoulder (10). Said annular sleeve (5) of the main portion (2) of the ring can be inserted between ducts (16, 17) that are inserted into one another, said projecting outer shoulder (6) of the main portion (2) abutting against the end of the outer duct surrounding the inner duct, and said projecting inner shoulder (10) of the secondary portion (3) abutting against the end of the outer tube that is inserted into the outer duct.

A passenger cabin for a means of transport is provided, which comprises an upper passenger deck and a lower passenger deck. The floor of the upper passenger deck comprises a lower and an upper region arranged therebeside, which are interconnected via a step or a ramp. There is an aisle in the lower region. The floor of the lower passenger deck likewise comprises a lower and an upper region arranged therebeside, between which there is a lowered aisle which is arranged so as to be laterally offset from the aisle of the upper passenger deck. The available surfaces of the upper and the lower passenger deck are mirror-symmetrically arranged. In this way, the space available can be used very effectively in order to accommodate more passengers.

A roof flashing can include a bottom half and a top half. The two halves can each have a plate and a neck portion projecting away from the respective plate. The neck portions define portions of an aperture configured to encircle and seal against a post projecting away from a roof. At least part of the first neck portion can be slidably receivable in the second neck portion and the two portions can define a neck when the bottom half and the top half are engaged with one another.

A seal assembly, including a first conduit member having a first seat and a second conduit member having a second seat. The second conduit member is coupled to the first conduit member such that the first and second conduit members are movable between at least a rest configuration in which the first and second seats are a rest distance apart, and a compressed configuration in which the first and second seats are held at a compressed distance apart. The compressed distance is less than the rest distance. The seal assembly also includes a flexible seal received between the first and second seats such that the flexible seal is compressed when the first and second conduit members are in the compressed configuration, the flexible seal expanding axially outwards when compressed to engage with an inner surface of a body in which the seal assembly is received.
