Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
201 words
A mechanism for a sliding door, window and the like, comprising: a stationary frame; a profiled elastic sealing strip and a circumferential pressure hose inflatable by a pressure fluid; a pressure transmission bar mounted by way of a pivot, arranged at least partly between and contacting both said hose and said strip; said bar having a surface which is substantially normal to the plane of said frame and is subjected to the action of said hose, said bar pressing said strip against a countersurface associated with said strip; at least one sash slidable in said frame; wherein one of said frame and said sashes constitutes an operative member having a lateral surface thereon, substantially parallel to said plane, which surface constitutes said counter-surface; means for supporting said hose between said operative member and said bar; and a lever arm associated with said bar substantially parallel to said lateral counter-surface; and wherein a component of a pivotal movement performed by said lever arm, directed transversely to said plane, is utilized for pressing said strip, wherein terminal portions of said hose and said bar are held by said supporting means in said operative member, a terminal portion of said bar constituting said pivot.
Claim 2
Dependent Claim
201 words
A mechanism for a sliding door, window and the like, comprising: a stationary frame; a profiled elastic sealing strip and a circumferential pressure hose inflatable by a pressure fluid; a pressure transmission bar mounted by way of a pivot, arranged at least partly between and contacting both said hose and said strip; said bar having a surface which is substantially normal to the plane of said frame and is subjected to the action of said hose, said bar pressing said strip against a countersurface associated with said strip; at least one sash slidable in said frame; wherein one of said frame and said sashes constitutes an operative member having a lateral surface thereon, substantially parallel to said plane, which surface constitutes said counter-surface; means for supporting said hose between said operative member and said bar; and a lever arm associated with said bar substantially parallel to said lateral counter-surface; and wherein a component of a pivotal movement performed by said lever arm, directed transversely to said plane, is utilized for pressing said strip, wherein terminal portions of said hose and said bar are held by said supporting means in said operative member, a terminal portion of said bar constituting said pivot.
Claim 3
Dependent Claim
32 words
The mechanism as defined in claim 1, wherein said supporting means is constituted by two grooves in said operative member respectively holding therein the terminal portions of said hose and said bar.
Claim 4
Dependent Claim
30 words
The mechanism as defined in claim 1, further comprising an extension for anchoring said operative member, said extension being mushroom-shaped and fitted into a groove which widens towards its base.
Claim 5
Dependent Claim
24 words
The mechanism as defined in claim 3, wherein said extension is provided in at least one of said hose, said bar and said strip.
Claim 6
Dependent Claim
74 words
The mechanism as defined in claim 1, wherein said bar is a rigid profiled rail having a pressure receiving arm which points away from said pivot and is directed substantially transversely in relation to said plane of the frame, and includes said bar surface, and wherein said bar has a pressure arm which points away from said pivot and is directed substantially parallel to said plane of the frame, and constitutes a lever arm.
Claim 7
Dependent Claim
19 words
The mechanism as defined in claim 5, wherein said strip is mounted on said pressure arm of the bar.
Claim 8
Dependent Claim
21 words
The mechanism as defined in claim 5, wherein said pressure receiving arm is curved for fitting the shape of said hose.
Claim 9
Dependent Claim
53 words
The mechanism as defined in claim 1, wherein said strip has a pressing surface which, together with said counter-surface, forms an acute angle in the open position, said acute angle being such that said pressing surface and said counter-surfacE are substantially parallel in a sealing position and in a position closely adjacent thereto.
Claim 10
Dependent Claim
28 words
The mechanism as defined in claim 1, further comprising return spring means for urging a pressing region of said strip away from said counter-surface in the open position.
Claim 11
Dependent Claim
40 words
The mechanism as defined in claim 9, wherein said return spring means is constituted by a resetting extension which is integral with said strip and is likewise elastic, said extension bearing against said operative member, which also supports said bar.
Claim 12
Dependent Claim
30 words
The mechanism as defined in claim 10, wherein said extension is formed by a hose-like hollow profile region on said strip, which region can be filled with the pressure fluid.
Claim 13
Dependent Claim
42 words
The mechanism as defined in claim 11, wherein said profile region communicates with a fluid-pressure system for said hose so that at least part of the pressure fluid is fed from said hose to said profile region when said hose is emptied.
