DOOR WITH OPTIONAL RIGHT-LEFT OPENING INSTALLABLE DOOR LEAF

The invention relates to a door, in particular a fire protection door with a frame and a door leaf that can be installed either on the right or left, which is designed to be approximately symmetrical with respect to a horizontal center plane and can be fixed in the vertical frame beam area by means of hinge tabs on the hinges between the door leaf and the frame.

Door leaves of this type have previously been built and handled for optional installation with a right- or left-hinged door leaf in such a way that the entire door, i.e. door leaf and frame, was positioned at the installation site in one of two positions parallel to the plane of the door opening to be closed by 180° and then the frame was fixed in the masonry or similar around the door opening. This regularly requires a correspondingly variable design of the frame and its adaptation to the selected type of hinge at the installation site. This not only means that the frame is constructed accordingly and is therefore expensive, but assembly at the installation site is also time-consuming and demanding in terms of the need for specialist skills.

The invention is based on the task of making a door of the type mentioned above simpler and, above all, more suitable for optional assembly at the factory.

to provide preparatory training so that work at the installation site can be carried out more quickly and easily.

This is achieved according to the invention in that the frame, which is to be used for both installation options of the door leaf in the same installation position in the masonry containing the door opening &ogr;. etc., has hinge pockets in its two vertical beams that are approximately opposite one another and that the hinge tabs of the frame-side hinge parts can be optionally inserted into the hinge pockets of one or the other of the two vertical beams of the frame frame and can be fixed in these, depending on which of the two stop positions the door leaf is positioned in by rotating it by 180 ° parallel to the frame frame plane.

According to the invention, the frame is thus fixed to the masonry in the same installation position in a known manner for both types of door leaf stop, so that the frame does not undergo any change and is not more complex in terms of construction than frame frames for door leaves with only one predetermined stop type. Installation is therefore quick and easy. Thanks to the hinge pockets and openings provided in the area of both vertical beams of the frame for the latch and bolt of the lock unit, the door leaf can be installed in the frame with either a right or left hinge, so that only the usual design of the door leaf in terms of the known procedure with regard to the implementation of the lock unit and the symmetrical arrangement of the hinges or hinges needs to be provided. In principle, it is possible to arrange the hinges at the top and bottom not exactly symmetrically to the horizontal center plane of the installed door leaf; Deviations from this are possible, which are then taken into account in the correspondingly different arrangement of the hinge pockets in the vertical beams of the frame.

In a particularly preferred design, a snap lock is provided between the hinge pockets and the hinge flaps of the frame-side hinge parts, which makes the installation of the door leaf on the frame particularly easy and

designed to save time. In particular, the hinge pockets are provided with a locking lug that is spring-loaded against the wide surface of the hinge flap relative to the hinge box housing and thus the vertical beam, and that, when engaged, engages behind a surface of the hinge flap facing in the opposite direction of insertion. Preferably, each hinge pocket has a receiving groove for the front edge of the hinge flap in the end region of the insertion section of the hinge flap, which preferably narrows in the direction of insertion, which holds the hinge flap against displacement and opens into shaft walls that accommodate the wide sides of the hinge flap, one of which is spring-loaded against the adjacent surface of the hinge flap and has a part of the snap closure, in particular the locking lug, which, when engaged, engages behind the edge of an opening in the hinge flap facing in the opposite direction of insertion.

The strap pocket is preferably provided with a housing formed in one piece from a bent part, which is fixed in particular as a single part to the vertical beam, for example via two tabs extending from the housing in the longitudinal direction of the beam.

The spring-elastic shaft wall provided within the hinge pocket can be incorporated into the receiving groove as a single element next to the inserted hinge flap and can be pivoted in this groove by a small angle perpendicular to the width of the hinge flap under the force of a spring element such as a helical compression spring, spring clip or the like, for which the receiving groove, which narrows towards the base of the groove, provides the necessary pivoting space.

In a particularly preferred embodiment, the spring-elastically pivotable shaft wall is formed in one piece on the sheet metal bent part of the hinge pocket housing in its end region facing away from the insertion gap of the hinge pocket for the hinge flap and derives its spring-elastic loading from the spring properties of the sheet metal material.

Furthermore, the design is preferably such that the snap lock can be released from outside the vertical beam, in particular by means of a key that can be inserted from the reveal side of the beams through correspondingly arranged openings in the beam, the adjacent housing wall of the hinge pocket and the spring-elastically pivotable shaft wall into a recess in the engaged hinge flap and can be rotated within this with a bit projecting laterally from the key shaft in such a way that the bit engages behind the opening edge of the shaft wall facing the hinge flap, in particular reaches the bent-out inclined surface of the locking lug bent out of the spring-elastic shaft wall facing the hinge flap. In a further preferred embodiment, at least the openings in the vertical beam and the resilient shaft wall can be designed in the shape of an elongated hole and the key can have a shape adapted to this and a shoulder facing the bit, between which and the bit there is a distance that is slightly larger than that between the outer surface of the vertical beam and the surface of the resilient shaft wall facing the hinge flap in the vicinity of the associated openings, so that when the key is turned after the bit is inserted, the latter slides along the edge of the opening of the shaft wall facing the hinge flap and the shoulder slides along that of the outer surface of the vertical beam, the bit slides onto the inclined surface of the locking lug, pushing it out of the locking connection with the hinge plate, and that the recess in the hinge flap is connected to its front edge by a slot through which the key can pass, whereby the surface forming the locking closure with the locking lug of the hinge flap on both sides of the slot on the adjacent edge of the recess.

The symmetrically constructed door leaf, which is regularly provided with rebates at least in the area of the stop on the vertical beams of the frame, can be designed without rebates in the area of the upper edge and in the area of the lower edge, so that it can be used in both types of stop, i.e. in positions rotated by 180° in the door plane, without any changes to the door leaf. It would be conceivable to fit a special

the rebate element in the upper edge area of the selected installation type, which would have to be carried out during assembly of the door at the installation site. In the preferred version, the door leaf is designed with a rebate running all the way around, so that both types of fitting can be selected without making any changes to the door leaf itself and the advantage of the rebate system on the upper horizontal beam of the frame is retained.

A further preferred embodiment consists in that the insertion slots provided in both vertical beams for inserting the hinge flaps into the hinge pockets - and if necessary the openings for inserting the key - and the openings for the engagement of the latch and bolt are pre-punched so that they can be broken out, the latter being punched out to the extent that a correspondingly arranged security bolt is provided in the hinge-side reveal area of the door leaf, which engages in one of the openings for the latch or bolt when closed.

The invention is explained in more detail below with reference to the preferred embodiments shown in the drawings.

frame 3. With regard to the horizontal center plane 4, the door leaf 2 is designed symmetrically with regard to the hinge parts 11 of the hinges (or hinges) 5 on the door leaf side; the same applies to the handle set 9 with regard to the recesses to be provided in the door leaf for their necessary implementation when changing from left-hand to right-hand hinges, as is generally known. The hinge pockets 10 belonging to the hinges or hinges 5 are provided in a spatially adapted manner in both vertical beams 6 of the frame 3 in preparation for both optional types of hinges in such a way that the hinge tabs 14 - Figure 1c - of the hinge or hinge parts 12 on the frame side can be inserted into the hinge pockets 10 - Figure 1c.

Figure 1b shows a vertical section - shown in abbreviated form with regard to the vertical extension of the frame 3 and door leaf 2 - of a door leaf 2 with fold formations 43 in the upper and lower horizontal area of the door leaf 2, which, as in Figure 1c, also has lateral folds 43, i.e. is folded all the way around. The frame 3 is inserted into the door opening 8 of the masonry 7 in a constant installation position, regardless of the type of stop selected for the door leaf 2, as is indicated in Figure 1b. In the horizontal section Figure 1c, the door leaf 2 is shown in abbreviated form with regard to its width and shown cut with regard to the right vertical beam 6 at the height of a hinge pocket 10; the hinge tabs 13 of the hinge parts on the door leaf side are indicated. The door leaf 2 is installed with the hinge on the left and is inserted into the hinge pocket with the hinge tab 14 of the hinge 5, while the hinge side of the door leaf shown on the left with regard to the handle set is only indicated by the lock pocket 15.

Figure 2 shows an enlarged section through the hinge pocket 10 from Figure 1c in a slightly different view on a differently designed vertical beam 6 of the frame 3; the door leaf 2 is only indicated. The hinge pocket 10 is designed as a single piece as a bent sheet metal part with regard to its housing 17 and has an insertion gap 18 for inserting the hinge tab 14. The hinge tab 14 is inserted into the hinge pocket through this insertion gap 18 and in this state engages with its front edge 40 in a receiving groove 19 which is in a corresponding bulge in the hinge pocket housing 17.

is shaped accordingly. The housing wall 21 opens into the receiving groove 19, along which one broad side of the inserted hinge flap runs approximately parallel, while a shaft wall 20 designed as a single element runs parallel to the other broad side of the hinge flap 14, which is also inserted into the receiving groove 19 with its foot area adjacent to the front edge 40 of the flap, as can be seen from Figure 2. The receiving groove 19 is designed in the adjacent area of this shaft wall 20 to narrow towards the groove bottom, such that the hinge tab 14 is held in the receiving groove with its front edge area without play, while the shaft wall 20, which is designed as a single part, can be pivoted away from the adjacent broad side of the hinge tab by a small angle, namely against the force of a helical compression spring 26, which is inserted - preferably pre-tensioned - between the broad side of the shaft wall 20 facing away from the hinge tab 14 and an opposite wall of the hinge pocket housing 17. Two such compression springs 26 can also be arranged in parallel, viewed in the direction of the beam. The hinge pocket housing 17 rests with its housing side having the insertion gap 18 on the cover section of the vertical beam 6 and with its wall running at right angles thereto and supporting the helical compression spring 26 on the reveal section of the vertical beam 6 and is attached to it by tabs 31, as can be seen in Figure 3. The reveal section is provided with an insertion groove 16 for a fire protection strip running in the longitudinal direction of the beam. The shaft wall 20 has a bend 22 to facilitate the insertion of the hinge flap 14. In the area adjacent to the bend 22, a locking lug 23 is bent out of the shaft wall 20 in the direction of the hinge flap 14, which, when the hinge flap is inserted, overlaps a surface 25 facing away from the front edge 40 as the edge of a recess 24 of the hinge flap 14, as can be seen in Figure 2. The helical compression spring 26 engages the shaft wall 20 approximately in the area of the bent locking lug 23. Before the hinge flap 14 is inserted, the shaft wall 20 is pivoted under the spring pressure into the insertion path of the hinge flap 14, so that during the insertion process the hinge flap 14 is first at the bend 22 and then, with increasing pivoting of the shaft wall 20, against the pressure of the helical compression spring 26 on the inclined surface 39 pointing in the insertion direction.

the locking lug 23 until it slides along the broad side of the hinge flap 14 adjacent to the spring-loaded shaft wall 20 and snaps into the recess 24 in the final state of insertion. In this state, the front edge 40 of the hinge flap 14 engages the bottom of the receiving groove 19 and the locking surface of the locking lug 23 overlaps the surface 25 in the corresponding edge area of the recess 24 with practically no play.

Figure 3 shows a slightly different design embodiment, in which the hinge pocket housing 17 is composed of two housing parts 27 and 28, which, during the fastening of the housing, engage with two oppositely protruding tabs 22 in the reveal section of the vertical beam 6 - shown only in the hinge pocket section - for example by spot welding. The spring-loaded shaft wall 20 is previously inserted into the receiving groove 19 of the hinge pocket housing 17, indicated with respect to the outer contour. Instead of the helical compression spring 26, a band-shaped spring clip 29 is inserted here. The shaft wall 20 is provided with two locking lugs 23 spaced apart in the longitudinal direction of the beam, which engage in two correspondingly arranged recesses 24 of the hinge tab 14 when engaged. For this purpose - as described in connection with Figure 2 - the hinge tab 14 is first pushed through the insertion slot 30 of the vertical beam 6 with its front edge 40 leading and enters the insertion slot for the hinge tab 14 formed by the shaft walls 20 and 21. The three arrows in the area of the outer housing part 27 indicate the play-free reception of the hinge tab 14 in the assembled hinge pocket 10. In the final insertion state, the positioning is as shown in Figure 2.

Another particularly preferred embodiment according to Figure 4 is shown in Figure 4a, partially sectioned, in its relationship to the dashed cross section of the vertical beam 6 considered here. It can be seen from this that all parts of the belt pocket 10, namely the housing and the spring-elastic shaft wall 20', consist of a one-piece bent sheet metal part, such that the shaft wall 20' merges into the wall of the housing 17 in its end region facing away from the receiving groove 19. The formation

As in the previously described embodiments, the locking lug 23' is bent out in one piece by partially cutting out the bent part wall forming the layer wall 20', but here in the end area of this wall facing the receiving groove 19. A bend for inserting the hinge tab is not required, since the layer wall 20' is held so that it can pivot in its end area facing away from the receiving groove 19. The spring-elastic loading towards the insertion path of the hinge tab 14 is achieved by the spring-elastic properties of the bent part sheet and the geometry of this sheet metal part. When inserting the hinge tab 14 shown in Figure 4a below before insertion, the front edge 40 engages the inclined surface 39 of the locking lug 23' during the insertion between the shaft walls 20' and 21, the rest of the locking process is as described in connection with Figure 2. From the partially broken side view according to Figure 4b it can be seen that the layer wall showing the locking lug 23' is here functionally formed by a central section which is created by two incisions 38 from the relevant wall section of the bent sheet metal part. The recess 24 of the hinge tab 14 shown in Figure 4b below in a corresponding wide view is open with a narrower slot 42 towards the front edge 40. The surface covered by the locking lug 23' in the locked state consists here of two surfaces 25' formed on both sides of the slot 42 at the edge of the recess 24.

In this embodiment, a device for releasing the hinge flap 14 from the locking in the hinge pocket 10 is shown as a representative of the other examples described above. This is done with the help of a tool in the form of a key 32 according to Figure 4c. The key has a key shaft 35, at the end of which a projection in the manner of a bit 33 is formed. Viewed towards the key handle, the bit 33 is spaced from a shoulder 34 by a recess in the key shaft. In order to accommodate the key shaft, viewed from the outside of the reveal section of the vertical beam 6, the latter is provided in the contact area of the hinge pocket 10 with an elongated hole-shaped opening 36 adapted to the shape of the key shaft, which is connected to similarly designed elongated hole openings 37 in the housing wall 41 adjacent to the frame beam.

of the strap pocket housing 17 and in the spring-elastic shaft wall 20', so that the key can be inserted through these three aligned openings with its bit 33 into the recess 24 of the inserted and locked strap tab 14. By turning the key from this inserted position, the bit with its edge facing the handle reaches the edge of the opening 37 in the shaft wall 20' on the side facing the strap tab. A pulling movement on the key 32 in the direction of the key handle causes the spring-elastic shaft wall 20' to pivot, so that the locking lug 23' comes out of engagement with the surface 25' of the recess 24 of the strap tab and the strap tab can be pulled out of the inserted position. However, the shoulder 34 provided on the key shaft 35 simplifies the return of the locking lug 23' against the spring-elastic feed force of the shaft wall 20' and simplifies the force and handling in that the distance between the shoulder 34 and the edge of the bit 33 facing it corresponds to the distance between the edge of the opening 36 in the reveal wall of the vertical beam 6 facing the key handle and the edge of the opening 37 in the spring-elastic layer wall 20' facing the hinge flap 14 in such a way that when the inserted key is turned, the edge of the bit 33 slides onto the inclined surface 39 of the locking lug 23' while the key shaft is supported by the shoulder 34 and thus moves the latter from the locking position on the Surface 25' is lifted out. The required rotational movement of the key can be up to 180°, as shown, but with a different arrangement of the slot-shaped openings 36 and 37, the rotational path can also be halved. After disengaging, the hinge flap can be pulled out of the inserted position in the disengaged position of the key due to the slot 42 without the key bit protruding into the recess 24.
