Description

SPECIFICATION Turnable window arrangements This invention relates to turnable window arrangements comprising a windcw casement pivotably mounted on a window frame and of the slide-hinged type.

Norwegian Patent Application No. 761222 discloses a slide-hinged, turnable window where the window casement, in its closed position, covers pivot arms with fastening mountings. The window casement can be dismounted from the window frame, for example in connection with the replacement of the glass of the window, in opened positions of the window, in that the fastening screws of the fastening mountings of the pivot arms are then exposed for dismounting.After the pivot arms with associated fastening mountings are dismounted from the window frame, but are permanently hanging on the window casement, the remaining dismounting of the window casement from the window frame can take place in a relatively simple manner by obliquely positioning the window casement in the inner opening of the window frame so that pivot pins, which are fastened to the window casement at its one side edge, can be drawn, in turn and order, out of associated pivot bearings in associated slides. On subsequent mounting of the window casement in the window frame, it is relatively complicated to get pivot pins of the window casement to enter into associated pivot bearings in the slides at the same time as the window casement is supported in the window frame.

Accordingly, the present invention resides in a turnable window arrangement which comprises a window casement adapted to pivot about a vertical axis in a window frame, said casement being mounted at one edge thereof for pivoting about a first pair of mutually opposite, upper and lower pivot pins which are in permanent slidable engagement with respective upper and lower horizontal portions of said window frame as well as being axially displaceable inwardly into and outwardly from upper and lower pivot bearings associated with respective upper and lower horizontal portions of said window casement and said window casement being also pivotably and turnably mounted via a second pair of mutually opposite, upper and lower pivot pins to outer ends of respective pivot arms which at inner ends thereof are pivotably mounted in said window frame, each of said first pair of pivot pins having an axially inner and realtively short cylindrical bearing portion and an axially outer, relatively elongate and conically pointed threading-in portion, said first upper pivot pin being adapted with said window casement ob liquely positioned in said window frame to be threaded outwardly from or inwardly into said upper pivot bearing of said casement while the latter is abuttingly supported by said window frame via said first lower pivot pin, and said second pair of upper and lower pins being adapted with said window casement in a vertial position disposed across said window frame and supported in the latter by said first pair of pivot pins to be dismounted from or mounted in associated pivot bearings in said window casement or in associated pivot arms.

There is thus achieved an especially simple and effective solution for mounting the window casement in the window frame, first and foremost by employing slides equipped with the said first pivot pins instead of employing pivot pins fastened to the window casement.

For one thing, the window casement can form a guide surface for leading the pivot pins into place in the pivot bearings in the window casement. By mounting, when only the first pivot pins are fastened in position in the window casement, the window casement occupies an unstable position and it is an advantage that, in such an unstable position, one can ensure,easily and rapidly, the placing of the window casement in a stable position.

This is done quite simply, by threading the second pivot pins in position in associated pivot bearings in the window casement by a simple swinging of the pivot arms which are permanently fastened to the window frame.

Immediately the second pivot pins are in place in associated pivot bearings in the window casement the window casement is securely in place in a stable position.

It is preferred that the lower pivot pin is rotatably mounted in the casement portion and in axially undisplaceable engagement with the latter by means of a transversely extending fastening means (fastening plate, fastening screw) which is desirably inserted at the lower casement portion of the window casement from its normally inwardly facing side, the second upper pivot pin being preferably threaded into free axially displaceable engage ment with the upper bearing-forming cavity of the casement.

By locking the pivot pin of the lower pivot arm in engagement with the associated pivot bearing in the window casement, the window casement can be effectively secured in place in controlled engagement with the window frame. The pivot pin of the upper pivot arm can safeguard the engagement between case ment and frame without fastening screws and only with the aid of the self-barring locking action of the pivot arm. If desirable, however, the pivot pin of the upper pivot arm can also be locked in engagement with the associated pivot bearing in the window casement in a corresponding manner as for the lower pivot arm.

Where one avoids dismounting the pivot arms from the window frame by dismounting the window casement from the window frame, one is not dependent on having fasten ing mountings and fastening screws of the fastening mountings easily accessible in the window frame. In this connection, the objective is a solution where with an especially shielded reception of the fastening mountings of the pivot arms outside the opening of the window frame, several advantages can be achieved.It is preferred that the pivot arms which are pivotably connected to the window casement at its vertical central axis, have a length between the pivotal axes at opposite ends of the pivot arm, larger than half the dimension of breadth of the window casement, the pivotal axis of the pivot arm in the frame being arranged outside the opening of the window in a bearing arranged at the joint between a vertical frame portion and a horizontal frame portion.

With the afore-mentioned solution, there is the possibility, for one thing, of adjusting the window casement from a normally closed position to a corresponding accurately closed position with the window casement turned 1800. By this, one can, for example, employ the same locking means (but different stationary locking members) in the two closed outer positions. By being able to lock the window casement also in the 1800 turned position,the window casement can be secured in place in a stable position for was#hing of the outer side of the glass of the window.

In order that the invention can be more clearly understood, convenient embodiments thereof will now be described, by way of example, with reference to the accompanying drawings in which: Fig. 1-4 are horizontal sections of the window casement in four different positions relative to the window frame, Fig. 5 is a scrap horizontal section through one vertical frame portion of the window frame at its lower end and showing one pivot arm of the window casement projecting laterally outwards from the frame portion, Fig. 6a and 6b are cut off vertical sections, in perspective, showing the pivot pins fastened to their respective slides on associated guides fastened to a lower and an upper horizontal frame portion, Fig. 7a, 7b and 7c are perspective representations showing three phases of the mounting of the window casement in the window frame, Fig. 8 is a scrap horizontal section of frame and casement at one side of the window, Fig. 9 is a perspective view of a mounting as shownin Fig. 8, Fig. 10 is a perspective view of another mounting according to Fig. 8, Fig. 11 is a perspective representation of an alternative form of fastening of a pivot arm, via a fastening mounting, to the lower casement portion of the window casement, and Fig. 12 is a plan view of a locking plate in the fastening mounting of Fig. 11.

Referring to Fig. 1 a window casement 10 is received in a normally closed position in a window frame 11. In Fig. 2, the casement 10 is shown in a 90 rotated position relative to the frame 11, in Fig. 3 the casement 10 is shown in a 1500 rotated position, and in Fig.

4, in a 1800 rotated position, that is to say in a closed condition in an outer, rotated position.

The casement 10 is pivotably mounted at one vertical casement portion 10a (Fig. 7a) of the casement via a first upper pivot pin 12 (Fig. 6a) and a first lower pivot pin 13 (Fig.

6b), and is pivotably mounted at the vertical central axis of the casement 10, via a second upper pivot pin 14 (Fig. 1-4) and a second lower pivot pin 15 (Fig. 5).

The pivot pins 12 and 13 are fastened to their respective slides 17 and 18 which are in permanent sliding engagement with their respective associated guide rails 19 and 20 on horizontal upper frame portion 11 b and lower frame portion lid of the frame 11. The pivot pins 12 and 13 are pivotably mounted in their respective pivot bearings 21 (Fig. 8) which are received in upper horizontal casement portion 10b and lower horizontal casement portion 10d of the casement. The pivot pins 12 and 13 are provided innermost with a relatively short cylindrical pivot bearing surface 12a and 13a respectively and are provided outermost with a more elongate, conical entering surface 12b and 13b which permits entry of the pins 12, 13 in associated pivot bearings while the casement is obliquely disposed relative to the frame.

The pivot pins 14 and 15 are permanently fastened to the outer end of their respective pivot arms 23, 24 which are pivotably mounted at the inner end about the pivot pins 25, 26. The pivot pins 25, 26 are permanently fastened to the vertical frame portion 1 lea just at the joint by the upper horizontal casement portion 10b and at the lower horizontal casement portion 10d respectively, that is to say laterally outside the opening of the frame in associated pivot bearings 27 and 28.

The pivot pins 14 and 15 are provided with cylindrical bearing surfaces in pivot bearings 29 received in horizontal upper casement portion 10b of the casement and in lower horizontal casement portion 10d of the casement respectively. An annular groove 31 is formed in the bearing surface of the lower pivot pin 15, a fastening screw 32 (Fig. 1) being fastened for easy release through the pivot bearing 29 and projecting inwardly into the annular groove 31 for locking the pivot pin against axial movement relative to the pivot bearing.

The fastening screw is preferably screwed into the casement portion 10d from the side surface which normally faces inwards into the space existing within.

In a position as shown in Fig. 2 one can, after the fastening screw 32 is released from the annular groove 31 (Fig. 9), first release the pivot arms 23, 24 with associated pivot pins 14, 15 from the casement. Thereafter, by obliquely positioning the casement 10 in the frame 11, the casement can be allowed to slide out of engagement with the pivot pins 12, 13 on the slides 17, 18 in turn and order and the casement will thereby be made ready for removal from the frame. In Fig. 7a, there is illustrated a threading of the casement 10 on the lower pivot pin 13 on the slide 18 while the latter is pushed to a support position in one corner of the frame.In the position illustrated in Fig. 7a, the pivot pin 13 is easily visible at the lower frame portion 1 1d of the frame and the under side of the casement 10 can,if necessary, form a guide surface for guiding the pivot pin 13 into place in the associated pivot bearing of the casement. In the position which is shown in Fig. 7b, pivot pin 13 of the slide 18 has ensured a stable support for one lower corner of the casement and there is the possibility of guiding pivot pin 12 of the upper slide 17 into place in the associated pivot bearing 21 of the casement on swinging around the casement 10 as shown by the arrow 33, by gripping the casement with the one hand and, at the same time, pushing the slide 17 with the other hand, as is illustrated in Fig. 7b.After the pivot pin 12 is led into position in the pivot bearing 21 in the casement, the casement can be put in place in a vertical position as is indicated by the arrow 34 in Fig.7b. In the unstable position as illustrated for the casement in Fig. 7b, the casement can be secured in a stable position by swinging the pivot arms 23, 24 into place towards the central axis of the casement and allowing the pivot pins 14, 15 to slip into place in the associated pivot bearings in the casement. Finally one can safeguard the turning engagement between the pivot pin 15 and the associated pivot bearing 28 in the casement 10 by fastening the fastening screw 32 into place in the annular groove 31.

In Fig. 8, there is shown a fastening mounting 35 fixed to the frame 11 and an angular corner mounting 36 fixed to the casement 10.

The mounting 35 is fixed with a fastening screw 37, via a fastening plate 38, to the frame 11. In the fastening plate 38, there is stamped and bent out a stopforming flap 39 directed inwardly towards the opening of the window which is secured in place in an obliquely inwardly directed position by means of an inclined locking screw 40. The mounting 36 is fixed with fastening screws 41, via two legs 36a and 36b (see Fig. 10) of the mounting, to the casement 10. In one leg 36a of the corner mounting 36, there is stamped and bent out an equivalent stop-forming flap 42 which is secured in place in an obliquely outwardly directed position by means of an inclined locking screw 43.On swinging around the casement from the open position (Fig. 2) to the closed position (Fig. 1), the flaps 39 and 42 are adapted to be brought into a selflocking engagement as shown in Fig. 8 so that there can be ensured an effective locking engagement between frame and casement on closing the window. The opposite side edge of the window can be closed in the usual manner by means of a locking bolt (not shown) which cooperates with a conventional lock member. On closing the window to the position shown in Fig. 4, the locking bolt can engage with an equivalent lock member on the opposite side of the frame.

In Fig. 9 the fastening mounting 35 is illustrated in perspective. There is shown a main portion 44 in which there is formed the pivot bearing 27 for pivot pin 26 of the pivot arm 24. The pivot pin 26 is preferably permanently connected to the inner end of the pivot arm 24 and is precluded from axial movement in the associated pivot bearing of the main portion 44.

In Fig. 11, there is shown an alternative construction of pivot pin 15b of the pivot arm 24 where an annular groove 31b is arranged closely up to the upwardly facing surface of the pivot arm 24. There is illustrated a mounting 45 which is fastened in a cavity on the under side of the lower horizontal casement portion 10 (shown in broken lines) of the window casement 10. The mounting includes a sleeve portion 46, axis 46a of which is shown coinciding with the axis of the pivot pin 15b, and a transverse fastening plate 47 having a central bore 48 for the reception of a fastening screw and having opposite duct-shaped guides 49 for the reception of a lock plate 50 shown further in Fig. 12.

The lock plate 50 is provided with two forkshaped arms 51, 52, Each arm is recessed, in steps, along the inner edge and the outer edge so that there is defined outermost a relatively broad gap 53, after which there follows a somewhat narrower locking gap 54 and thereafter an innermost, reverse T-shaped, relatively narrow gap 55. Between the gaps 53 and 54 there are designed obliquely extending guide surfaces 56 while between the gaps 54 and 55 there are designed concave transition edges 57. External shoulder portions 58 are shown at outer ends of the arms 51, 52, that is to say at the transition from a stop-forming head portion 59 to a recessed control surface 60.

As shown in Fig. 11, after the mounting 45 with the associated lock plate 50 is secured in place on the lower casement portion 10 of the casement 10 by means of a fastening screw through the gap 54 in the lock plate and the bore 48 in the fastening plate 47 of the mounting 45, the lock plate 50 is moveable in a direction inwardly into the mounting 45 from the position illustrated in Fig. 11 to a locking position with the locking gap 54 ar ranged just below the sleeve portion 46. In the position illustrated in Fig. 11 for the lock plate 50, the pivot pin 15b can be freely pushed axially inwards into and outwards from the sleeve portion 46. After the pivot pin 15b is pushed axially in place in the sleeve portion 46, the pivot pin 15b can be locked in place by pushing in the lock plate 50 on threading the locking gap 54, with a relatively narrow fit, into place in the annular groove 31b of the pivot pin 15b.
