DOOR R WINDOW WITH FLUID-OPERATED SEAL This invention relates to doors and windows, and particularly to a fluid-operated seal which is interposed between the frame and the closure element of a door or window and may be inflated by means of a pumped fluid. I a
In its more specific aspects, this invention is concerned with an improvement in the door or window arrangement disclosed in the commonly owned, published German Pat. application No. 2,044,686. The
I published application discloses a window whose frame carries a diaphragm pump. An elastomeric tube extends about the opening in the frame and is connected with the pump. An operating arm 'is mounted on the frame and permits liquid to be driven by the pump into the tube for sealing the gap between the window frame and a casement, andthe liquid to be withdrawn into the pump to facilitate opening of the window. I
In closing the window of the German application, the easement is moved into the closed position and the arm of the pump is then operated to inflate the sealing tube. It isadvisable to hold the easement in its closed position while operating the pump in order to prevent the casement from being displaced by the expanding tube and to prevent misalignment of the frame and casement. The operation thus may require two hands. It is a primary object of the instant invention to improve the known window arrangement, which is equally applicable to a door, so that it can be operated by one hand in a continuous movement even if wind pressure or the like tends to move the casement or door away from the closed position.
With this object and others in view, as will hereinafter become apparent, the invention provides a door or window arrangement in which the pump is mounted in or on the frame in the known manner. The closure device of the arrangement, such as the easement or a window or panel of a door, is secured to the frame for movement toward and away from a closed position in which it obstructs the opening in the frame. It carries a manually operated handle by means of which the closure device may be moved. The handle also is movable relative to the closure device between at least two positionsl A tubuIarQpIiabIe sealing member is interposed between the closure-device and the frame and communica'tes with the pump. Coupling elements on the frame and the closure device engage each other in the closed.
position of the latter. A motion transmitting linkage connects the coupling element on the closure device to the handle, and an analogous linkage connects the coupling element on the frame to the pump so that a fluid, more specifically a practically non-compressible liquid, expands the sealing tube when the handle is moved on the closed closure device.
Other features of this invention and many of the attendant advantages will readily become apparent as the invention becomes better understood by reference to the following description of a preferred embodiment when considered in connection with the appended drawing in which: a
FIG. '1 is a fragmentary perspective view of an open casement window equipped with a hydraulic sealing device of the invention; I FIG. 2 illustrates the window of FIG. 1 in the closed condition in. section on the line IIII and on a larger scale than in FIG. 1; and
is conventional. As is not novel in itself, the sash l2 essentially consists of two wooden upright members 23 andtwo wooden horizontal members 23a bounding an opening permanently sealed by two parallel glass panes 12a, 12b held apart by spacers 12c, and fastened by putty'l2d, so that the wooden and glass elements of the sash l2 jointly constitute a closure for the opening in the frame 11.
In the illustrated upright member 13 of the frame 1 1, there is provided a vertically elongated recess l4 in which a diaphragm pump 15 is mounted. The pump. is of the general type disclosed in I-Iopkins U.S. Pat. No. 3,121,372. As shown in more detail in the patent, the pump essentially consists of a hollow e'lastomeric body capable of being expanded and compressed so that a liquid in the body is expelled or drawn back. The illustrated pump is elongated at right angles to the plane of FIG. 2, as is seen in FIG. 1, and is actuated by cooperating, wedge-shaped cams, obscured inthe drawing by the pump housing, of which one is attached toa bracket 16. The bracket projects through a slot-in the pump housing which permits the bracket to move longitudinally in the frame member 13. The bracket 16 carries a coupling fork 17 which projects from an upright face 18 of the frame member 13.
The face 18 is partly covered by a molding 22 of approximately J-shaped cross section through which the bracket 16 passes. The narrower flange 19 of the molding 22 extends in a plane parallel to that of the face 18 and provides an abutment for an elastomeric sealing the bight' of the molding 22 and also extends about theentire window opening. The tube 21 is adhe'sively fastened to the molding 22 in a manner not explicitly illustrated.
'The sole vertical member 23 of the sash 12 which is seen in the drawing fixedly carries the base 24d of a pivotally mounted handle 24. Thehandle is elongated horizontally in the illustrated position, and may be turned on its base until it extends vertically downward, as indicated by an arrow in FIG. 1. The shaft 24a of the handle 24 carries a pinion. 24b which meshes with a rack on a flat, vertical drive rod :26, the pinion being received in a cavity of the sash member 23, and the drive rod 26 in a groove extending over much of the sash face =30which is parallel and opposite to the face 18 in the 12 is swung into its closed position, the roller 25 enters the gap between the tines of the horizontally open fork l7, and the cooperating roller and fork couple the drive rod 26 to the bracket 16. When motion is transmitted from the handle 24 to the roller 25 by the shaft 24a, pinion 24b and drive rod 26, such motion is further transmitted by the bracket 16 to the pump 15. When the handle 24 is swung downward from the illustrated horizontal position while the window sash 12 is held in its closed position by means of the handle, the pump forces liquid through a heavy-walled rubber hose 15a into the tube 21 so as to expand the tube until it seals and locks the sash to the frame 11. The sealing strip 20 is received between the tube 21 and the flange 19 of the molding 22 and held in pressure contact with the flange by the expanded tube 21.
The rod 26 has a lower or locking end 29 which is retracted within the groove of the sash member 23 when the handle 24 is horizontal, as shown in fully drawn lines in FIG. 1. When the window is closed, and the handle 24 is swung downward, the locking end 29 projects from the bottom of the sash, as indicated in broken lines, and passes through an apertured plate 29a into a recess or receptacle in the bottom member of the frame 11, thereby further locking the sash 12 to the frame 11 in the closed position. 7
When the handle 24 is returned to the illustrated position, the non-illustrated cams of the pump 15 permit the diaphragm of the latter to be brought back to its starting position by return springs, and liquid is returned to the pump 15 by the pressure of the ambient air on the tube 21. 7
While the invention has been described with specific reference to a casement window, it is applicable without changes or with minor changes obvious to one skilled in the art to windows having reciprocating sashes, to windows having sashes swinging about a horizontal axis, to windows equipped with fittings that'per-' mit a casement to be swung alternatively about a vertical or a horizontal axis, and to swinging or sliding doors. The drive rod 26 whose toothed main portion transmits movement from the handle 24 to the coupling roller 25, and also transmits movement to the locking end portion 29, may be employed for actuating other fittings directly or indirectly, as is known in itself, for example, in windows capable of-alternating swinging movement about two axes perpendicular to each other. The apparatus illustrated in the drawing actually may be a glass door instead of being a window, as described above. I
It should be understood, therefore, that the foregoing disclosure relates only to a preferred embodiment of the invention, and that it is intended to cover all changes and modifications of the example of the invention chosen herein for the purpose of the disclosure which do not constitute departures from the spirit and scope of the appended claims.
