Abstract: Threshold system for a domestic door of the type comprising a pivotable panel, the threshold system including a stationary sill adn a weather-strip carrier mounted on the lower edge of the pivotable panel. When the pivotable panel is in the closed position, the sill and the weather-strip carrier are generally parallel and slightly spaced from one another along a vertical axis. The space between these elements is closed by two weather-strips mounted to the weather-strip carrier and extending on either side of a water-catch pan formed on the sill element. The water-catch pan collects water droplets passing through the outer weather-strip.

Abstract: The present invention relates to a weather-strip to be used for doors or windows having sliding panels, more particularly on the meeting uprights of the panels. The weather-strip consists of a rigid base in the form of an inverted T from which two sealing wings run, generally parallel, each comprising an inner portion connected to the base, an outer portion and a curved intermediate part which connects the inner portion to the outer portion. The outer portion is offset in relation to the inner portion, in a generally transversal direction to the wings.

Abstract: A weather strip for doors and windows of the casement and awning types, primarily for domestic use, and the like, made of two different thermoplastic materials, one being relatively flexible but having sufficient mechanical rigidity so as to prevent shrinking or stretching of the weather strip when installed, and the other being considerably more supple and flexible. The weather strip has a T-shaped base with anchoring means on the vertical bar of the T-shaped base, and two supple wings made of the more flexible material, extending parallel to one another but spaced apart and secured to the opposite end portions of the horizontal bar of the T-shaped base. This weather strip, which can also take some other forms, particularly in respect of its gripping leg, defines between its supple wings an air space which constitutes an excellent thermal barrier between inside and outside conditions which is particularly useful in cold climates.

Abstract: A catch member adapted to be secured to the end of a grille member for securing same to a window parallel to the inner surface thereof. The window sash presents inwardly facing surfaces which have longitudinally extending shallow grooves forming seats of the catch members. The catch members comprise a stem and a head portion integrally formed therewith. The head portion has a base from whose lower surface the stem depends, and an arcuate arm flexibly secured to the base along one edge thereof. The arcuate arm overlies the base and its major portion is spaced apart from the upper surface of the base whereby it can yield when the window grille is being fitted to or removed from the window. The arcuate arm is curved in one direction and flat in the opposite direction.
