. The present invention relates to a device for safely operating, securing, and locking in various positions, windows, doors or the like which are adapted to be-moved either in the inward direction or in the outward direction. So-called window stay devices for fixing a window or the like in a partly open position, are. old.- The said stay devices comprise a control rod or lever pivoted to the window frame or sash, respectively, or to an equivalent part, and provided with recesses, and a stopping member provided on the window sash or frame, respectively, oran equivalent part, the said stopping member being adapted to 'cooperate withthe recesses of the rod in order'to retain the same.

The purpose of the invention is to obtain a stay of the kind in question which also constitutes a window operating device and which is simple, consists of few, simple and little damageable parts, has no screws, springs, et cetera, and is easy to handle, and which, thus, may be operated silently and easily with one hand only and which at the same time resistant and durable.

The problem has been solved according. to the invention in such a way that the stopping member is embodied as a rotatably mounted sleeve or the like provided with a hole for the rod so that in an unsecured position the rod is guided in the sleeve: with only insignificant play, and the lower limiting portion of the hole is given a shape exactly adjusted to co-operate with the recesses which here are provided on the underside of the rod. Thus, the stopping engagement of the rod and the sleeveis produced by moving the rod downwards or by the rod falling due to its own gravity. Its moving out of position and the operation'of'the' window can be effected with one hand only by grasping" the free end of the rod. Moreover, the rod is of such a length and the securing points of the. same and the sleeve are located in such a way on the respective parts that the most advantageous lever action is obtained,

respectively, so that due to co-operation of the device employed with an inwardly moving win- Figure 1 being a front view of part of the window in closed position;

Figure 3 a section along the line III-III of Figure 1.

In Figures 4 and 5, which show the device mounted on an outwardly moving window, Figure 4 is likewise a cross section, and Figure 5 a front section; 7

Figures 6 and 7 show on a larger scale an embodiment of an operating handle and a partial view of the operating rod respectively, the operating handle being embodied in another way.

I indicates the window sash, 2 the window frame, and 2a the boarded window sill. One end of an operating and control rod 3 is pivoted to the window frame (Figures 1 to 3) or the window sash (Figures 4 and 5) respectively, and extends through a hole 4 in a socket or sleeve 5 or the like pivoted to the window sash or the window sill respectively, the said socket or sleeve forming a guide and stopping member for the rod. The size of the hole 4 is adjusted exactly to fit the rod 3, which in the embodiment shown has a cylindric shape so that the rod only moves with small play in the sleeve. The lower part (preferably half) of the hole has a rectangular shape; the lower edge portion 6 of the opening is adapted to engage recesses I on the underside of the rod in order to fix the window in the desired position, and has a shape adjusted tofit the recesses. In the embodiment shown the recesses 1 are rectangular or approximately rectangular, in axial section and the engagement portion 6 has a corresponding shape so that a secure engagement is obtained.

At its free end the rod has an operating handle which may be shaped as an arched plate or arm 8 which serves as a finger grip and is detachably secured (see particularly Figure 6) or as aball 8 (Figure 7). The said operating handle also prevents the rod from leaving the Sleeve.

The finger grip offers certain advantages over the ball handle, particularly due to the fact that it immediately indicates the operation of the rod and gives a sure engagement. The finger grip is fitted to the rod with the arched portion extending on one side or the other according as to whether the device is intended for leftor rightgoing windows. The arch-form of the engagement 8 may vary; the free end should be bent in such a way as to eliminate the risk of clothes, curtains et cetera being caught therein. The re'-.. cess in the rod end for the engagement may be arranged horizontally instead of vertically.

In the window sash or the window frame, re-

spectively, there is provided a locking member in the form of a fork-shaped projection provided with a notch 9, in which notchithe free end portion of the rod is adapted to be insertedatv the. closing of the window. The bearing surface 9'.,.

lies at the same level as, or possibly'somewhat above the lower: surface of the rod in free position. In order to facilitate the insertion there is provided a guide surface In. Different forms of locking members may also be employed. The rod is manufactured from some suitable metal or metal alloy, and should preferably be resilient so as to facilitate its moving in and'out of lockingposition over the notch.

In Figures 1 to 3 (see particularly Figure 3) the sleeve 5 is shown rotatably mounted. in the legs of a U-shaped stirrup It or the like secured to the window sash; According to Figures 4 and 5 the sleeve is turnable in a fitting l2 secured to the window sill. 5 indicates the bearing of the sleeve. I

The rod is mounted with play in such a way on a pin l3 secured to the end of a fork-shaped fitting I4 that the rod has a certain free motion relatively to the fixing point in the vertical position and alsointhe axial direction, if desired. This is necessary in order to permit the rod to sink so as to engage the stopping sleeve, 1.. e., to a. depth, corresponding to that of the recesses l, and it is also suitable in order to avoid the exact relative adjustment of rod, stopping sleeve and locking member 9 which else might be necessary at the mounting. In addition to the pin hole of'the rod end=having asomewhat larger diameter than the pin in the axial direction of the rod the end I5 of the rod facing the fork arms is formed with a rounded taper (see particularly Figure 7). Thus, a constant'contact against the fork arms is ensured during the oscillating movements of the rod so that noise is avoided.

If desired, the surfacesl5 may be made spherical in order to enable a universal movement of the rod if this should prove necessary in order to avoid jamming between rod and stopping sleeve orfor some other purpose. The pin hole is then accordingly modified.

In the neighbourhood of the fixing point, the recesses 1 are provided'nearer to each other and then farther from each other; and the distances are adjusted in such a way that the window may be stopped in positions of about mutually equal distances around the arc in which the rod moves.

If the device is to be attached to an existing Window, or possibly in other circumstances also, it may be necessary to insert spacing washers under thefixing means for the rod or guide member or both so that said rod and guide member may be in correct alignment with each other or with the" catch'whenv the window is closed.

The length of the rod, the position of its fixing point and the position of the sleeve are preferably adjusted so that an opening movement of about may be imparted to the window and so that the most suitable lever relation is obtained. Thus, starting from closed window, the distance between the inner (hinge) edge of the window sash and the fixing point of the rod should be larger than the distance between thesaid fixing point and that of the sleeve; the last distance, inits turn, being smaller than the distance be- ..tween the sleeve and the free end of the rod.

Due to the fact that the pivot moves inwardly relatively to the free end of the rod, the leverage of said freeend increases with the movement of .the window towards the closing position correspondingly increased turning moment with the operation of the window towards this position is obtained, and relatively less force is required for the said operation.

The function of the device is, in the first place, connected with the above indicated lever relations so that the window may be operated by the rod with, so to speak, less power consumption thaniby a direct grip on. the window. The device functions as follows. When the windiw' is closed the, outer end of the control rod 3 is located in the notch 9; due to the above-stated lever moment of the rod and, to the fact that the rod rests closely against the edges of the hole of the sleeve an effective securing of thewindow isensured 7 even if the other locking devices, if any, of the window are released. When opening the window one raises the control rod from the locking posi- -,tion by engaging, or grasping the operating handle, and moves the window inwards or outwards, respectively,: the rod gliding in the sleeve 5 during simultaneous turning of the sleeve. When the window hasbeen opened to the desired extent the control rod is lowered or dropped so that the respective recess I will enclose the engagement portion 6 of the sleeve, the rod thus being locked and the window stopped in the intended open position, In order to release the rod from the locking positionone need only raise the same towards the .upper edge of the. hole 4 and then the window may be freely operated again by the rod. When the window is being closed the outer portion of the rod glides or is movedupwards along the guide surface I0, and falls or is lowered into the notch 9 (Figure 3). I

Modifications of the embodiment shown are, of course, possible. Thus, the rod may have another shape than cylindrical and the recesses of the rod may have other shapes. The stopping sleeve may be embodied and mounted in another suitable way than the one shown. i e

The device may be used in windows having simple as well as double (coupled) sashes, and also in vertically swingable windows whereby it should be modified with respect thereto, and in doors of various kinds.

Having now described my invention, what I claim as new and desire to secure by Letters Pattent is:

1. In a stay device for windows, doors or the like having a hinged rod adapted to be adjusted and locked in different positions, the hinged rod being of substantially circular cross-section and provided in the known manner on the underside with notches, a substantially U-shaped bracket mounted on said sash, a guide member mounted rotatably in the legs of said'bracket and having an aperture in its lower portion, said rod passing through said aperture, a stationary pivot on the window frame nearer than is said bracket tothe axis of rotation of the window sash and a grip on said rod so that the window sash can be opened by pulling the grip of the rod.

2. In a stay device for windows having a fixed frame and a window sash hinged to said frame, a window actuating stay rod hingedly attached to said frame, a. substantially U-shaped bracket mounted on said sash, a guide member mounted rotatably in the legs of said bracket and having an aperture in its lower portion, the rod passing through said aperture and having transverse grooves therein and the lower portion of the guide 5 member having a projection to fit said grooves.
