HINGE DEVICES FOR PIVOT TYPE wmnows Filed Feb. 1, 1951 4 Sheets-Sheet 4 INVENTOR. GUJTAF P- H. L UNOGRfN A TI'ORNEYS United States Patent 2,717,412 HINGE DEVICES FOR PIVOT TYPE WINDOWS Gustaf Per Henry Lundgren, Stockholm, .Sweden Application February 1, 1951 Serial No..208,,864
8 Claims. *(Cl. 16-140) The present invention relates to pivot type windows, .i. e. to such windows in which hinge devices are positioned substantially on the horizontahor in .some cases the vertical, centre line of the window. More particularly the invention relates to hinge devices .for pivot type windows.
In pivot type windows having the hinge devices arranged substantially on the horizontal centre line of the window the hinge devices usually are mounted so'that the axis, about which the window pivots when moving from closed position to full ventilating position, takes up such a position with respect to the centre of gravity of :the movable window as :to secure the desired degree of balancing of the window. It is thus possible, for instance, to let the pivot axis of the hinge devices pass through the centre of gravity, resulting in :a complete balancing of the window, or else it can be arranged that-the turning axis isdisplaced a certain distance from the centre of gravity in such a direction, that the window tends to turn or'swing itself either from its closed position to its fullyopenposition, or, alternatively, from its fully open position --to .its closed position, for example. Irrespective ofthe positioning of the turning axis of the window it is customary :to provide the hinge devices with a brake, which opposes the turning of the window and .holds the window in the position to which it has been turned. I
As long as it can be assumed, that the window 'hasa definite centre of gravity, the requirements :on'the brake can be held low by placing the hinge devices so that a sufficient degree of balancing of the window about the turning axis is obtained. Lately it has, however, become customary to provide a Venetian blind between the panes of the window, and as a-result the position of the centre of gravity relatively to :the turning axis will depend on whether the Venetian blind is fully hoisted or fully or partly lowered. If the window is suitably balanced when the Venetian blind is wholly lowered, the window will-evidently be top-heavy when the Venetian blind is fully hoisted, and it will then be diflicult for the brake to :hold the window in intermediate positions in which it is 'set. Therefore, there is now a demand for 'more effective hinge brakes for pivot type windows.
The present invention has for its object 'to :meet said demand by improving the brake device in hinge devices for pivot windows, particularly windowssadapted to pivot on a horizontal axis.
According to this invention in a hinge device :for hinged windows a first part of the hinge device :is :provided with a circularly or otherwise curved channel housing a braking member, the said bra-king member being movable along the channel by a driving member on a second part of the hinge device upon .movement of the window, and the braking member is expansible by means of a set screw and adapted to press with an adjustable pressure against the opposing parallel curved surfaces of the channel.
Two embodiments of the invention will now be described, by way of example, with reference to the accompanying drawings wherein:
Figure 1 shows a hinge device comprising one embodiment of the invention, as viewed from the outside of a window,
Figures 2, 3 and 4 show the same vertical section taken on the line 22 in Figure -1 but with the hinge parts .shownin ditferent relative turning positions,
ice
Figure 5 shows another hinge device comprising the second embodiment of the invention, as viewed from the outside of a window, and
Figures -6, 7 and 8 show the same vertical section taken on the line 66 in Figure 5 but with the hinge parts shown in different relative turning positions.
In :Figures 1 to 4 of the drawings the partof the hinge device which is adapted to be secured to the window frame consists of a plate l l'provided with holes .10 for fixing screws, to which plate there are secured, for example by welding, two parallel circularly bent flanges 12 and 13 having a common axis 14 perpendicular to the plate 11. The flanges 12 and 13 define between themselves a guide channel 15 of uniform width 'inwhich ride two pins 16 and 17 mounted on a plate 118 which :is adapted to be secured :by means ofscrewsto the window sash, the said plate 18 preferably having the sarneshape as the plate 11. A brake member 19 is inserted in theguide channel 15 between the pins 1.6 and 17. The said brake member 19 consists of a band of spring steel which istbent approximately to the shape of a U, the branches 20and 21 of the U-shaped spring bearing against the guide flanges 12 and 13 respectively and the free ends of the two branches being bent over inwardly towards each=other so that overlapping lugs 22.and.23 respectivelyare formed, :the overlapping lugs extending transversely of the guide channel 15.
A slit 24 is provided in the guide flange 15 with the longitudinal axis of the slit extending 'paral-lelto the plane of the plate 11. The slit is of sufficient width to receive .a screw 25 which is screwed into a threaded hole at about the middle of the inner branch 2 1:of thespring 19. The screw 25, which is provided with a round head having a central hexagonal hole for a screw driver, is .intended to be screwed in sufiiciently far for its .free end to engage the opposite branch 20 of the brake spring 19 with a suitable pressure. As the pressure of the :screw 25 on the branch 20 increases the force with which the spring .19 presses against the walls 12 and 13 of thegu-ide channel will also be increased and :thus also braking action of the spring. Besides regulating the braking action of the spring the :screw 25 co-operatcs with-the slit 24 and serves to limit the path along which thebraki-ng spring 19 can move in the guide slot 15.
The hinge device just described operates in-the following manner.
When the window is closed the two main parts of each hinge device, one device being provided at each side of the window, take up the relative positions shown in Figure 2. During turning of the window-to its ventilating :position, the pins 16 and 17 move along the guide slot 15 the window turning about .-a fixed horizontal axis coincident with the axis 14. The pins 16 and 17 move the spring 19 in the guide slot 15 and, due to thetengagement of the spring 19 with the guide flanges 12 and 13, the turning'movement is braked thereby. By suitable ICgulation of the spring force, by means of the screw 25,, braking eflect can be made sufficientlyfgreattfor the window to be securely held by the braking spring 19 in every desired position in which it is set. The turning of the window about the horizontal axis coincident with the axis 14 is continued until the setting screw .25 engages the lower .end of the slit .24. This lastementioned posit-ion of the window corresponds to the normal fully-open ;posi- :tion. If the upper edge of the window is now moved further in the same direction, the window will pivot .about the trailing pins 16 resting in fixed bearings eachof which .isformed by the outermost lug 2.3.on the arrested braking spring .19 and the associated guide flanges 12 :and 13. Meanwhile the leading pin 17 is swung free from the guide channel 15, as isshown in Figure 4. v If the hingesdevices .are suitably placed it is "possible to turn the window through 180 degrees so that the outside of the window becomes readily accessible for cleaning.
In the embodiment shown in Figures 5 to 8 the braking member consists of two substantially rigid brake shoes 120 and 121, which are adapted to be pressed apart by a set screw 122 into engagement with the brake paths formed by walls 112 and a guide flange 113 of the guide channel 15. The set screw 122 is screwed into a threaded bore in the inner brake shoe 121 and has its smooth free end inserted into a con'esponding shallow recess 123 in the outer brake shoe 120.
The set screw 122 is provided with a round head having a central hexagonal cavity for a screw driver and is accessible for adjustment through a slit 124 in the guide flange 113. The slit 124 is of uniform width and has its longitudinal axis parallel to the plate 11.
When the set screw 122 is screwed towards the guide flange 112 the flanges 112 and 113 are resiliently pressed somewhat apart, wherefore, in spite of their rigidity, the brake shoes 120 and 121 are pressed against the brake paths with resilient pressure and the braking action increased. If desired, the brake shoes can be made elastically compressible to a certain degree, for example by providing the braking surfaces of the shoes with some elastically-compressible lining material.
In this embodiment the set screw 122 protrudes through the slit 124 and in addition to regulating the braking action co-operates with the ends of the slit 124, to determine the extent of the path along which the brake shoes 120 and 121 are movable in the slot 15.
When the window is closed the two main parts of each hinge device, one of which is provided on each side of the window, take up the relative positions shown in Figure 6. During turning of the window to its ventilation position the pins 16 and 17 move along the guide slot 15, the window turning about a fixed horizontal axis coincident with the axis 14, the pins 16 and 17 move the shoes 120 and 121 which, owing to their engagement with the guide flanges 112 and 113, brake the turning movement. By suitable regulation of the bearing pressure by means of the set screw 122, the braking efiect can be made sufliciently great to ensure that the window is securely held by the brake shoes 120, 121 in every position in which it is set. The turning of the window about the horizontal axis coincident with the axis 14 is continued until the set screw 122 engages the lower end of the slit 124. The said position of the window corresponds to its normal fully-open position. If the upper edge of the window is now swung further in the same direction the window will pivot about the pins 16 in fixed bearings each of which is formed by the brake shoes 120, 121, which are now stationary, and by the associated guide flanges 112 and 113, the pins 17 then swinging out from the guide channel 15, as shown in Figure 8. If the hinge devices are suitably placed it is possible to turn the window through 180 de- 1 grees so that the outside of the window becomes accessible for cleaning.
