Sealing arrangements in the form of strips

Claim 2

A sealing strip arrangement for sealing against a distal edge of a movable member, comprising, a substantially rigid supporting channel, a hollow tube of resilient and flexible material mounted within the supporting channel so as to fill, and having an external surface which is substantially flush with, the longitudinal mouth of the supporting channel, and two flexible and resilient leaves running along the tube's external surface which fills the longitudinal mouth of the supporting channel, the leaves being attached to the said surface of the tube at positions substantially inwardly of the distal edges of the side walls of the supporting channel and being adjacent and aligned with each other so as to define between them a longitudinally shaped open mouth for receiving the distal edge of the movable member, the movable member when it moves into the said mouth tending to flatten the tube thereby causing the leaves to press against the sides of the said member adjacent its distal edge while maintaining the tube in contact with the side walls of the supporting channel adjacent the latter's longitudinal mouth.

Claim 3

A sealing strip arrangement according to claim 1, in which the surfaces of the leaves on the inside of the said mouth which they define are covered with flock.

Claim 4

A sealing strip arrangement according to claim 1, in which the tube and the leaves are integral.

Claim 5

A sealing strip arrangement according to claim 1, in which the tube and the leaves are made of rubber.

Claim 6

A sealing strip arrangement according to claim 1, in which the tube is secured within the supporting channel by means of adhesive.

Claim 7

A sealing strip arrangement according to claim 1, in which the material of the tube has outwardly projecting lips which run longitudinally along opposite regions of its outside and extend over the outside of the side walls of the rigid supporting channel.

Claim 8

A sealing strip arrangement according to claim 1, in which the material on the tube has outwardly projecting lips which run longitudinally along opposite regions of its outside and are compressed between the tube and the insides of the side walls of the rigid supporting channel.

Claim 9

A sealing strip arrangement according to claim 1, including a resilient reinforcing carrier embedded within the longitudinally extending part of the wall of the tube opposite the part thereof on which the leaves are mounted.

Claim 10

A sealing arrangement for sealing the distal edge of a window glass which is movable in a direction parallel, with its plane, comprising a substantially rigid channel mounted at least partially around the window opening so as to have an open mouth facing towards the direction along which the distal edge of the window glass approaches in closing the window opening, a hollow tube of flexible and resilient material mounted and secured within the channel and extending longitudinally therealong so as to fill the channel and to provide an external surface closing off and substantially flush with the mouth of the channel, the material of the tube defining outwardly projecting lips which run longitudinally along opposite regions of its outside and are so positioned as to extend over the distal edges of the side walls of the channel and substantially to cover those side walls, and the material of the tube also defining two leaves of flexible and resilient material mounted on and extending longitudinally along the surface of the tube which closes the mouth of the channel but each positioned inwardly of the distal edges of the side walls of the channel, the leaves being aligned with each other and spaced slightly apart so as to define a longitudinally extending open mouth facing the distal edge of the approaching window glass, whereby to receive the distal edge of the window glass which partially flattens the tube and thereby causes the facing surfaces of the leaves to press against the sides of the window glass immediately adjacent its distal edge.

Claim 11

A sealing arrangement for sealing the distal edge of a window glass which is movable in a direction parallel, with its plane, comprising a substantially rigid channel mounted at least partially around the window opening so as to have an open mouth facing towards the direction along which the distal edge of the window glass approaches in closing the window opening, a hollow tube of flexible and resilient material mounted and secured within the channel and extending longitudinally therealong so as to fill the channel and to provide an external surface closing off and substantially flush with the mouth of the channel, the material of the tube defining outwardly projecting lips which run longitudinally along opposite regions of its outside and are so positioned as to extend over the distal edges of the side walls of the channel and substantially to cover those side walls, and the material of the tube also defining two leaves of flexible and resilient material mounted on and extending longitudinally along the surface of the tube which closes the mouth of the channel but each positioned inwardly of the distal edges of the side walls of the channel, the leaves being aligned with each other and spaced slightly apart so as to define a longitudinally extending open mouth facing the distal edge of the approaching window glass, whereby to receive the distal edge of the window glass which partially flattens the tube and thereby causes the facing surfaces of the leaves to press against the sides of the window glass immediately adjacent its distal edge.

Claim 12

An arrangement according to claim 9, in which the inside surface of the said mouth is substantially completely covered with flock.

Claim 13

An arrangement according to claim 9, in which the material of the tube has outwardly projecting lips which run longitudinally along opposite regions of its outside and are compressed between the tube and the insides of the side walls of the rigid supporting channel.

Claim 14

A strip according to claim 1 or 9, in which the tube is made of material of two different hardnesses, the part of the tube defining the part of the said surface at which the said leaves are attached being of the lesser hardness and the leaves being of the same hardness as that part of the tube.
