This invention relates to windows of the type that are movable about a horizontal axis, midway between the top and bottom thereof and more particularly has reference to a control device for adjustably moving the window between a closed position and a ventilating position and permitting complete opening of the window.

An object of the invention is to provide a control device on a horizontally pivoted window sash and means on the window frame cooperating with the control device to lock the window sash in closed position and to secure the window sash in various partly open positions.

Another object of this invention is to provide a control device on a horizontally pivoted window sash and means on the window frame cooperating with the control device to lock the window sash in closed position and to secure the window sash in various partly open and fully open positions.

Other objects of the invention will appear from the following description.

As shown in the drawings, the present invention is embodied in a window comprising a fixed frame I and a sash 2 pivotally mounted in the frame by means of two hinge members I and II, to swing about a horizontal axis intermediate the top and bottom of the sash.

A hinge member II is attached to ach side of the sash 2. Projecting from each hinge member II is a pivot element 3 and a pivot pin 5.

A hinge member I is attached to each side of the window frame I to cooperate with the corresponding hinge member II. As clearly shown in Figures 3-5, the hinge member I is provided with an abutment 4 for cooperation with the pivot member 3 of the sash and an arcuate slot 6 for guiding pivot pin 5 of the sash. Slot 6 is open at the top and closed at the bottom.

With the hinge structure shown in Figures 3-5 and described above, the pivot members 3 support the sash in the closed position and bear on the abutments 4. As the sash is opened, the sash is pivoted in a counter-clockwise position about an axis defined by the engagement between the lower portions of the pivot members 3 and the abutments 4 of the hinge members and the pivot pins 5 move downwardly in the arcuate slots 6 until pins 5 engage the bottom of the slot.

Further movement of the sash 2 in a counterclockwise direction causes the sash to be pivoted about a horizontal axis defined by the pins 5 in the bottoms of the slots 6. Under such circumstances, the pivot member 3 leaves the abutment 4 as shown in Figure 6 of the drawings.

According to the present invention, the window sash 2 is provided with a longitudinally slidable member 8 on each side thereof. The longitudinally sliding member 8 is associated with the sash as is clearly shown in Figure 8 of the drawing. Movement of the longitudinally sliding members 8 is effected by means of a cable surrounding the opening in the sash and actuated by means of a control lever Ill located at the bottom of the sash. As the control lever is moved in one direction, the member 5 on one side of the sash will be moved upwardly and the corresponding member 8 on the other side of the sash will be moved downwardly.

Projecting laterally from each vertically slidable member 8 is a pin 1. In accordance with the present invention, a member Ia is located adjacent each hinge member I on each side of the window frame. As clearly illustrated in Figures 3-5, each of the members Ia is provided with a curved slot for cooperation with the pin I carried by the vertically sliding member 8.

Figures 3-6 illustrate one suitable form of slot 9 in member Ia for cooperation with pin 1. This slot is open at one side of the fitting Ia for the introduction and removal of pin 1 as the sash is swung about its pivot axis. From the open end, slot 9 is inclined upwardly as indicated at 9b to a predetermined point and then is oppositely inclined downwardly as indicated at 9a to the closed bottom. The closed bottom of slot 9 is disposed opposite the open end of the slot.

When the sash is in the closed position, pin I is located at thebottom of slot 9 as shown in Fig. 3. To open the sash, lever it! is shifted to cause the slide member 8 to move vertically along the side of the sash and to shift pin '5 upwardly. The upward movement of pin 1 through the portion of slot 911 causes the window to shift about its pivot axis as shown in Fig. 4.

The downward movement of pin '1 through the portion 91) of the slot is produced by shifting lever in the direction opposite that of its first movement and the application of a slight force on the sash urging it to an open position. This downward movement of pin 7 will cause the sash to be further moved in a counter-clockwise direction about its pivot until the pin reaches the lower open end of slot 9.

Lever it, in addition to operating the sliding members 8 carrying the pins I, also serves to actuate the locking pin carried by the sash for cooperating with slots in looking members carried at the upper and lower portions of the sash. The inclination of the portion 9a of the slot in the members Ia corresponds to the inclination of the slot in the locking members carried at the upper and lower portions of the window so that when lever to is actuated to move the locking pins to an unlocked position, the movement of pin 7 in the portion 9a will shift the sash 2 through the proper angle about its axis to correspond with the movement imparted thereto by movement of the locking pins in the locking slots.

When the pin d is moved into the portion 9b of the slot in the members Ia, the locking pins also actuated by the lever iii will have left their slots. By shifting the lever. to a selected position, the pin 7 may be moved to a corresponding position within the slot 92) so that the window sash 2 will be inclined at the desired angle to maintain the sash in a predetermined partly opened position.

While the member Ia may be separate from the member I, it is desirable in some instances to have it formed as a part of the member I.

The control device is such that when the lever M has been moved in one direction and the window is unlocked, the lever has to be moved back in order to push the pins 1 into the outer parts 9b of the slots 9. This movement is facilitated by controlling the lever it with one hand and with the other pushing the sash 2 in the direction of movement. With the control lever it! it is very easy to obtain the desired size of the ventilation openings between the frame and the sash at the upper and lower sides. By moving the control lever in the opposite direction to push the pins I into the outer parts so of the slots 9, the control lever does not need to be turned essentially more than is required for the control of the locking pins. The control lever It! may be provided with means for securely holding it in certain desired positions corresponding to certain desired ventilating or partly open positions of the sash.

As before stated, when lever 19 is shifted, the pin 1 on one side of the sash will be moved in one direction and the pin 1 on the opposite side of the sash will be moved in the opposite direction. Due to the opposite movement of the pins 7 on the opposite sides of the sash, the slot 9 of the fitting Ia on one side of the window frame will appear as shown in Fig. 3 and that on the opposite side of the frame will appear as in Fig. '7.

Instead of forming the slot 9 as shown in Figs. 34, it may be constructed as shown at IS in Figs. 10 and 11. According to this embodiment, the pins '1 are moved into the ventilating range lflb of the slots [9 by shifting the control lever E5 in the same direction when the sash is unlocked and when it is opened for ventilating purposes. It is clear that the difference between this embodiment and that of Figs. 1-9 is that the inner part iSa of the slot according to Figs. 10 and 11 forms an approximately tangential extension of the arcuate outer part I91) while the parts 9a and 912 according to Figs. 1-9 are connected with an arc and form approximately tangential extensions thereof.

The slots 49 may have one or more recesses i I in the margin of the outer parts iQb into which the pins 1 may be brought to securely hold the sash in a certain open position or in any or" a number of definite ventilating positions.

As far as the invention has been described in connection with Figs. 1-11, it serves for control and holding of the sash in ventilating positions in which the sash is pivoted only a small angle with the lower side outwardly from the closed position with small ventilation openings at the top and bottom of the. window. The specially formed slot 9 for cooperation with the ventilating pin 1 may specially be used where it is desired to finely control the size of these'openings. The control device according to the invention, however, may also be utilized where it is desired to control the sash in open positions between and from the closed position. For that purpose the fitting I or another fitting may be provided with one or more so arranged recesses I2 that the movable pin 1 in the sash actuated by the control lever maybe inserted into any one of these recesses when the sash has been pivoted to a position in which the recess lies in the line ofmotion of the pin 1 (Figs. 12, 13, 15 and 16). When the pin 1 engages in one of the recesses i2, the sash 2 is securely held in the corresponding position. In windows with a sash pivotally mounted on a median axis it is often desired easily to be able to set the sash not only in ventilating positions in which the sash is pivoted, only a small angle from the closed position, but also in positions in which the sash is pivoted to positions from 90 up to 180 from the closed position. As shown in Fig. 16, the slot 9 may be replaced by an arcuate element provided with recesses I3, arranged in the fitting Ia, preferably integral .with the fitting I, which are similar to the recesses l2, only with the difference that they are located so that the pins 1 may be inserted into them when 5 the sash is in positions between and about 90 from the closed position.

The slot in the member Ia may have various forms. As shown in Fig. 15, slot 29 may have three inclined legs instead of two as shown in Figs. 37, 12 and 13, so that the pins 1 must be moved from closed position toward open position, then to closed position and again towards open position to shift the sash from closed position through the ventilating positions.

Figs. 17-19 are detailed views of hinges and control devices of a modified embodiment of the invention, which is especially suitable for use in windows of the type where the sashes when unlocked owing to their gravity and their sus pension tend to take a certain balanced and stable open position. The details of the hinges correspond to those already described and have similar reference characters. Movable pins 2|, however, in this example have been arranged in one side of the frame in guides 22 which can be made in one piece with the adjacent fitting part I of the hinge. Pins 2| are carried by longitudinally slidable members (not shown) similar to members 9 of Figure 8. The fitting II mounted on the sash has an extension with a slot 23. When the pin 2| which in Fig. 17 is shown in the upper end of the guide 22, is moved downwardly, it enters the slot 23 and the sash is pivoted as indicated in Fig. 18. If the pin 2| is moved further against the lower end of the slot 22, the sash is pivoted to the balanced position in Fig. 19. The pin 2| is then out of the slot 23 in the fitting II which has such a shape that the sash is free and may be freely pivoted in one or the other direction on one of the

pins

3 or 5 and secondly by the control device may be pivoted to a smaller opening and closed. The fitting with the slot 23 is so arranged on the sash that the pin 2| when it is moved back automatically enters the slot 23. The advantages of this construction reside in the control and secondly in that the pin 2| is disengaged when the sash reaches the balanced position.

A common feature of all the described embodiments of the invention is that the pins 1 or 2| for controlling of the different openings of the window in contradistinction to closing and locking in the closed position are movable at right angles to or near right angles to the pivotal axis of the sash, that is to or from the axis. Among the many obvious advantages in this arrangement is that the device is very simple, reliable and easy to control and it can easily be varied into many different embodiments according to the requirements.
