Device for sealing sliding windows, sliding doors and the like

Claim 2

Device for sealing sliding windows, sliding doors and the like having at least one casement displaceable in a single plane, comprising seal carrier means mounted within spaced formed in upper and lower profile shanks, respEctively, of the casement frame and constrained to move in a direction perpendicular to the displacement direction of the casement; sealing strip means carried by said seal carrier means in said space and extending in the displacement direction of the casement, said seal carrier means being actually movable perpendicularly to the displacement direction of the casement in a locking position of the latter for displacing said sealing strip means from a nonsealing position thereof into a position wherein it seals the casement, spring means supported by the casement frame and biasing said seal carrier means in said direction perpendicular to the displacement direction of the casing, fixed guide means extending in said displacement direction of the casement adjacent said casement frame, and lifting roller means supporting said seal carrier means and rollable along said fixed guide means, said lifting roller means cooperating with said fixed guide means for determining the position of said seal carrier means.

Claim 3

Device according to claim 1, wherein said fixed guide means comprises a guide rail having a profile formed with at least one depression therein, said lifting roller means being receivable in said depression so as to displace said seal carrier means in substantially vertical direction.

Claim 4

Device according to claim 2, wherein said guide rail is subdivided by a member formed with said depression whereby said seal carrier means are raised and lowered.

Claim 5

Device for sealing sliding windows, sliding doors and the like having at least one casement displaceable in a single plane, comprising seal carrier means mounted within space formed in the casement frame and constrained to move in a direction perpendicular to the displacement direction of the casement, sealing strip means carrier by said seal carrier means in said space and extending in the displacement direction of the casement, spring means supported by the casement frame and biasing said seal carrier means in said direction perpendicular to the displacement direction of the casing, fixed guide means extending in said displacement direction of the casement adjacent said casement frame, lifting roller means supporting said seal carrier means and rollable along said fixed guide means, said lifting roller means cooperating with said fixed guide means for determining the position of said seal carrier means, said fixed guide means comprising a guide rail having a profile formed with at least one depression therein, said lifting roller means being receivable in said depression so as to displace said seal carrier means in substantially vertical direction, and support rollers rollably supporting the casement on said fixed guide rail, said guide rail being so profiled and said depression being so formed that said support rollers, without variation in the vertical position thereof, and said lifting roller means supporting said seal carrier means are movable on the same plane, said lifting rollers means, in closing position of the casements, being rollable into said depression.

Claim 6

Device for sealing sliding windows, sliding doors and the like having at least one casement displaceable in a single plane, comprising seal carrier means mounted within space formed in the casement frame and constrained to move in a direction perpendicular to the displacement direction of the casement, sealing strip means carrier by said seal carrier means in said space and extending in the displacement direction of the casement, spring means supported by the casement frame and biasing said seal carrier means in said direction perpendicular to the displacement direction of the casing, fixed guide means extending in said displacement direction of the casement adjacent said casement frame, lifting roller means supporting said seal carrier means and rollable along said fixed guide means, said lifting roller means cooperating with said fixed guide means for determining the position of said seal carrier means, said fixed guide means comprising a guide rail having a profile formed with at least one depression therein, said lifting roller means being receivable in said depression so as to displace said seal carrier means in substantially vertical direction, and support rollers rollably supporting the casement on said fixed guide rail, said guide rail being so profiled and said depression being so formed that said support rollers, without variation in the vertical position thereof, and said lifting roller means supporting said seal carrier means are movable on the same plane, said lifting rollers means, in closing position of the casements, being rollable into said depression.
