NL1033868C2 - Locking mechanism for e.g. door construction, has double combined espagnolets for inner and outer rotating frame construction in relatively fixed frame, where espagnolets are connected by connector - Google Patents

Abstract

The mechanism has window latch (1) and double combined espagnolets (A, B) for an inner and outer rotating frame construction in a relatively fixed frame (7). The espagnolets are connected by a connector, and a connection pin is provided in one of the espagnolets, where the frame construction meets the requirements of wind and watertightness for an outdoor situation by applying single or double rebate. An outer wing frame is associated with the fixed frame or an inner wing such that minimum profile dimensions act as non-constructive intermediary element.

DOUBLE ESPAGNOLET CLOSURE WITH INTERCUPLED COUPLING FOR IN AND OUT ROTATING WINDOW STRUCTURE

The invention relates to a closing mechanism for a window or door construction that pivots inwards and outwards. This closing mechanism is suitable for inward and outward opening window constructions according to the principle from the patent application 'Window construction' Nr. 8700419 dated 20 Feb 1987 10 'Two way opening window' Nr. GB2203784 dated 18 Feb 1988, both applications were submitted by the undersigned at the time. Said window construction works according to the principle of two window wings hinged on one and the same side in a fixed frame. The inner window wing hinges in the outer wing; together they are hinged in the fixed frame. The outer window wing is always connected to either the fixed frame or the inner wing so that it can be small in size.

The present closing mechanism consists of a double espagnolette that is operated with one window latch. The espagnolets are equipped with traditional point closures and vertical blocking. The latter goes into effect as soon as the relevant sash is in the open position.

The window catch directly operates the first espagnolette vertically up and down. In this case the second espagnolet is set in motion indirectly by a coupling piece on the first espagnolet and a connecting pin on the second espagnolet. Due to the relative position of the point closures with vertical blocks on the two espagnolets, the window construction can be opened inwards by turning the latch a quarter turn clockwise; or by turning a quarter turn further, be opened to the outside. By turning the latch back half a turn clockwise, the 1 033 B 68 -2 window construction is closed again.

The closing mechanism is described below on the basis of an exemplary embodiment with the aid of the following drawings: Figure 1 shows a fragment on the closing side of a window with the closing mechanism in the closed position. The figure contains a diagrammatic front view and side view and two horizontal sections.

Figure 2 shows the same fragment in the open position inwards.

Figure 3 shows the same fragment in the open position to the outside.

In Figure 1, the window structure is in the closed position. Window latch 15 l is directed vertically downwards, the two point closures 2 on espagnolets A and B are closed in position X. As a result, the two window wings and the fixed frame are mutually secured. In figure 2 the window construction is turned inwards in the open position. Window latch 1 has been turned a quarter turn counter clockwise. As a result, the two espagnolets A and B move down one turn (from X to Y) and point closure 2A is disconnected. As a result, window wing 5 can move freely inwards, while the vertical blocking 4A ensures that the position of the window latch remains horizontal and that the window can again be closed unhindered.

In figure 3 the window construction is turned outwards in the open position. Window latch 1 is turned counterclockwise half a turn. As a result, the two espagnolets move one further down (from Y to Z) and the point closure 2A is closed again. Point closure 2B is released and the interconnected window wings 5 and 6 can move out freely as one wing, while the vertical blocking 4B ensures that the position of the window latch remains unchanged and the window can be closed unhindered again.

The window latch 1 is designed to be sufficiently tight to allow the distance between this window latch and the fixed frame 7 to be sufficient, so that injuries to the hand during turning out (fig. 3) can be avoided.

In use, the closing mechanism combines the advantages of a traditional inward opening window and an outward opening window. For example, the window can be opened (but not exclusively) with objects on the window sill inside or with the sun protection downwards, to the fresh air unhindered, while it can be opened to the inside for (incidental) washing. For apartment buildings, the costs of a window cleaning system can thus be saved.

A further application example is situations with a balcony or terrace, where depending on the weather conditions the space inside and outside can be used alternately without the open window getting in the way.

The closing mechanism can also be used in (escape) doors, which in normal use may have to turn inwards, but in emergencies need to turn outwards.

Claims (10)

A closing mechanism to be operated with one window latch 05 consisting of a double combined espagnolette for an inward and outwardly rotating window construction according to the principle of two hinged window wings within a relatively fixed frame. 2. A closing mechanism as claimed in claim 1 which, by operation with one window latch and two espagnolets which are mutually connected by a coupling piece on one and a connecting pin on the other espagnolet, can position the single or multiple point closures, that the window can be opened and closed successively inwards and outwards. 3. A closing mechanism as claimed in claim 1 or 2, wherein the window construction meets the reasonable requirements of wind and water tightness and is suitable for an outdoor situation through the use of single or double rebates. 4. A closing mechanism as defined in any of the preceding claims, wherein the outer window wing is always connected to either the fixed frame or the inner wing so that it can be minimal in profile size and acts as a non-structural intermediate element. A closing mechanism as claimed in any one of the preceding claims, wherein the movement from one espagnolette to the other is transmitted by a coupling piece on one and a connecting pin or cam on the other espagnolette, which when opening the window 1033868 . - ψ -5- can be disconnected horizontally. A locking mechanism as defined in any of the preceding claims in reverse form, wherein the inner window wing opens outward and the outer window wing opens inward. A locking mechanism as defined in any of the preceding claims applied to a door structure. 10 8. A closing mechanism as defined in any of the preceding claims in combination with other common closing mechanisms within one window construction such as, for example (but not exclusively), down-window and / or top-down window. 9. A closing mechanism as defined in any of the preceding claims made of metal, wood or plastic or a combination of these materials. 20 A closing mechanism as defined in any of the preceding claims, provided with a right-angled window latch in a laterally truncated embodiment to prevent injury to the hands when turning out. 25 30 1033 8 68
