United States Patent 1,760,994 6/1930 Piotti Primary Examiner-Dennis L. Taylor Attorney-Wenderoth, Lind and Ponack ABSTRACT: A sash-construction having a notch against which a swing window or similar closing element, particularly a window swinging outwardly, is capable of being stopped, said window with its hinges is fixed to a separate narrow panel which is slidable in the plane of the normally closed sash and with the panel ends being guided with respect to the mutually parallel sash-sills. The ends of the narrow panel carrying the window hinges are in cooperative relation with a profile fillet applied to sills or posts. The slidable narrow panel carrying the window hinges is formed near its ends with a slipper or similar slide element, capable of slidably cooperating with the profile fillet present on the sill or post in question, while the edge of the panel carrying the window hinges abuts a case-shaped end of a profile fillet fixed to a sash-portion in which case a resilient elastic draught-strip is secured.
PATENTEU M29 l9? FIG.1.
I N VEN TOR. JORDAAN KNAPP Adm/M06 1 026/7449 W AT TORNEYS SASH-CONSTRUCTION This invention relates to a sash-construction having a notch against which a swing window or similar closing element, particularly a window swinging outwardly, is capable of being stopped.
In practice, especially in high-rise construction, difficulties are experienced when cleaning the windowpanes on the outside. When the dimensions of the window are not too great, one may manage with a hand tool such as a cleaning gear held in a clamp which is fixed to a pole. This, however, is uneasy and certainly not undangerous. With somewhat greater window dimensions it is not possible to clean the window on its outside from inside.
The invention has for its objective the provision of a sashconstruction of the type described above wherein the disadvantages pictured hereinabove are removed. According to the invention this is achieved in that the window with its hinges is fixed to a separate narrow panel part which is slidable within the closed plane of the sash and with its ends guided with respect to the mutually sash-sills. The narrow panel is further preferably provided with one or more ventilation windows or grids which are selectively openable.
The construction of the invention makes it possible to move the attached narrow panel window in its opened position together with the part as a result of which and through the related formed opening, the outside surface of the window becomes accessible and can be cleaned from inside the buildmg.
The invention may be applied to a window as well as to a door, both of which are rotatable on a horizontal shaft. In the latter case the window, in its center, is made to hingedly rest on brackets, which latter in turn are hingedly fixed to e.g. the sash-posts.
It is efficient when the ends of the panel carrying the window hinges are in cooperative sliding relation with a profile fillet as applied to the sills when the sash and panel move horizontally, or as applied to the posts of the sash when the sash and panel are mounted to move vertically.
For reducing friction, the slidable panel part carrying the window hinges is formed near its ends with a slipper or similar slide element, capable of slidably cooperating with the profile fillet of the related sill or post part of the window. This mea sure ensures an easy sliding of the panel part carrying the hinges, thereby doing away with the necessity of chiseling out special grooves.
For achieving an efficient sealing, the longitudinal edge of the panel carrying the window hinges abuts a case-shaped end of a profile fillet fixed to an adjacent edge of the related sashpart, in which case a resilient elastic draught-strip is secured.
The invention is explained below with reference to the drawing, in which:
FIG. 1 shows shows front elevational view of the sash-com struction of the invention with the window in its closed position.
FIG. 2 is a front view of the sash-construction of the invention with the window opened and moved into a position in which it can be readily cleaned from inside and FIG. 3 enlarged, fragmentary crosssectional view taken substantially on the line IlI-IlI of FIG. 2.
FIG. 4 a similar cross-sectional view taken on the line IV-IV of FIG. 2.
The sash, which has opposite top side, bottom side, and lateral side portions, and may consist of wood is represented by 1, while the window 2 is provided with a window pane 3. The window 2 is swingingly mounted in the sash by means of suitable hinges 4 and is designed preferably to be swung outwards. According to the invention the hinges 4 are fixed in a narrow panel or part 5 which is disposed slideably in a cross direction, i.e. within the closed plane of the window and is guided therein on the upper sill 6 and the lower sill 7. Panes 8, 9, 10 or 11 can be arranged in the part 5, or ventilation grates or the like which, if desired, may be of the type admitting of being selectively closed or opened.
By moving the panel 5 as shown in FIG. 2 when the window is opened, a second opening 12 is provided enabling the window 2 to be cleaned in its opened position from inside.
A normal dog-lock is represented by 13 in FIG. 2 with the aid of which the window 2 can be locked in its closed position.
The sash-sills 6 and 7 are formed with a suitable profile fillet or track 14 as represented in section in FIGS. 3 and 4.
A glider or glide shoe 15 secured to the panel 5 by means of a T-profile bracket 16, as with the aid of screws, is complementally formed with a track or guideway to be in cooperative sliding relation with said profile fillet 14. The glider l5 may be made from synthetic material whereas for the track or profile fillet 14 and/or the T-profile 16, respectively, preferably a noncorrosive material, such as aluminum is chosen.
On its outer face side of abutment with the window 2, the profile fillet 14 is formed with a grooved case 17 in which the thickened portion of a draughtproof means 18 in the shape of a resilient weather strip is secured. Furthermore the case 17 forms the stop for the window 2 in its closed position.
The lower sill 7 is also provided preferably with a similar profile fillet 14 which cooperates with a like glider 15 which is secured to the part 5 in the way described hereinbefore. Said profile fillet 14, as shown in FIG. 4, has also as its object to guide the spanner or the casing 19 ofa window adjusting rod.
As shown in FIG. 1, in the closed position of the window 2, part 5 abuts the turned-off resilient strip 20 embedded in a profile fillet in a known manner. Thus an efficient draught exclusion is provided between the panel 5 when it abuts the sashpost 21.
It should be observed that the details as shown in FIG. 3 have been omitted from FIG. 4 because the view is taken on line lV-lV at a point beyond the lower glider, wherein the profile fillet is in cooperative relation with a like glider which is fixed to the slidable window panel part 5.
Though drawn and described with reference to a window, door or similar closing element which is rotatable on a vertical hinge-shaft, the invention may equally be applied, as already observed before, to any element capable of swinging around a horizontal hinge-shaft. The panel part comprising the hingeshaft thusly is slidable in a vertical sense is mounted then for cooperation and slidable movement within and between the opposed upright sash-posts. Then the closing element rests in its center hingedly on brackets which in turn are hingedly fixed to said upright sash-posts 21.
