In the ends of the tubes slide locking pins (8), which engage, when the door is locked, in corresponding recesses (9) made in the frame (1). The tubes have actuating openings (10) through which actuating elements for the locking pins (8) pass, in order to move the latter when the locking device is actuated.

Description

Security door and security device for installation in a door

The present invention relates to a security door with a frame (frame) and a wing (door leaf) attached to it, wherein on the periphery of the wing several locking bolts are provided which can be displaced in their longitudinal direction in metal tubes by means of a locking device and which are in a locking position via protrude the peripheral edge of the wing and protrude into the receptacles provided in the frame when the door is closed and are completely received in the wing in an unlocked position. The invention further relates to a security device for retrofitting in a conventional door.

A generic security door is known from GB-A-2 133 456. With it, the metal tubes extend from two housings arranged centrally in the door, in each of which a lever mechanism is housed, to the edge of the door. Exactly one safety bolt is arranged in each metal tube. An actuating member, which is connected to the lever mechanism housed in the housing, urges its actuation. through the front opening of the metal tube facing the respective housing.

In the known security door, it is disadvantageous that, if at all, it can only be produced with considerable effort by retrofitting from a conventional door with a wing which is generally made of lightweight construction. This is because the housings receiving the lever mechanism must be embedded in the sash, which can be impossible, in particular in the case of door sashes with only a small thickness. Furthermore, if it is even possible for the doors to be inserted into the casement in the case of corresponding doors, insert the tubes into the corresponding cavities in the cavities provided for receiving the tubes after the housing has been inserted and then connect them to the housings. This results in a connection of the pipes to the housings of only relatively low strength and rigidity. The stiffening of the door leaf caused by the built-in of the known security door is therefore relatively low.

In other known security doors of the type mentioned at the outset, the securing bolts are zen in guide sleeves provided on the peripheral edge of the door leaf and arranged in such a way that their axes converge at one point, but at least in a narrow area. A lock is arranged here, which moves the locking bolts from the locking position into the unlocked position and vice versa by means of actuating rods housed longitudinally displaceably in the interior of the door leaf.

Furthermore, it is known to provide locking strips on the circumferential edge of the door leaf, which have a plurality of bolts which are distributed over their extent; The locking strips can be displaced in their longitudinal direction, the latches arranged on them and projecting beyond the peripheral edge of the door leaf engaging in receptacles in the door frame.

Finally, on the inside of the door leaf, horizontally extending locking bars are known, which have locks which can be actuated on opposite sides and which can move into the adjacent door frames. Such locking bars, however, require that additional locking pieces be attached in the area of the frame. The present invention has for its object to provide a security door of the type mentioned, which can be manufactured with minimal effort by retrofitting a conventional door that may already be in use. The security door according to the invention is intended to offer a high degree of security against break-ins. At the same time, the door leaf is to gain inherent stability and its security against the frame is to be improved.

This object is achieved in accordance with the present invention in that metal tubes penetrating the door leaf and extending over its entire width and / or height are provided, in which two safety bolts are guided in opposite directions at least in the outer sections, and in that the Pipes between their sections serving to guide the securing bolts each have at least one actuating opening arranged in the tube wall, through which at least one actuating member coupled to the securing bolts on the one hand and the locking device on the other hand passes. According to the invention, a plurality of metallic tubes thus pass through, which are preferably arranged parallel to one another, the door leaf continuously from one side to the other. After these pipes extend across the door leaf without interruption, it is considerably stiffened and stabilized. In the locking position, each of the metallic tubes is fixed at both ends via the extended safety bolts locked in the door frame. In this way, an invisible “grid” is formed in the case of a plurality of tubes arranged parallel to one another in the door leaf, which simultaneously encompasses the locking mechanism and stiffens the door. By the actuating members for displacing the securing bolts entering through actuating openings provided in the wall of the metal pipes and into the pipes, it is avoided that these are completely interrupted; this is of particular importance with regard to the stiffening of the door leaf. For example, it is impossible to enter even lightly constructed door leaves which are designed according to the invention.

A particular advantage of the invention is that it is possible to convert conventional doors to doors according to the invention without teres is possible. Because it is not necessary to make recesses for receiving any housings or the like in the door leaf. Rather, after the actuating members for the securing bolts protrude laterally from the metal tubes, the actuating mechanism can be placed on the outside of the door leaf. Only small openings which correspond to the actuation openings of the metal tubes used are to be made in the door leaf. The device suitable for retrofitting in an unsecured door results from claim 15. To assemble them essentially only need - provided that it is not a door leaf with a tubular chipboard, in the factory-provided, suitable for receiving the metal tubes-like cavities - holes are drilled in the door leaf and the metallic tubes are inserted into these cavities or holes and the locking device is installed and connected to the safety bolts.

In order to accommodate the actuating mechanism or a part thereof, a U profile can be provided on the inner surface of the door, which may be covered later Rail are applied, the introduction of a recess receiving the actuating mechanism into the door being dispensed with. For receiving or for engaging the actuating mechanism acting on all securing bolts, however, a recess can also be made in the inside of the door leaf, which can be provided with a cover after assembly of the actuating mechanism and the lock.

The metallic tubes are expediently arranged horizontally in the door leaf. Advantageously, there are at least three tubes arranged distributed over the height of the door leaf. The locking device preferably comprises at least one essentially vertically arranged push rod which is displaceable in its longitudinal direction and to which the securing bolts are coupled by means of links. The vertical push rod can thus cross all horizontally arranged metal tubes, ie all safety bolts can be actuated by the push rod by means of identical coupling links. Two vertically displaceable push rods are particularly preferably provided, each of which actuates a part of the total existing safety bolt serves; the two push rods are coupled to one another in such a way that they execute opposite movements. In this way, a negative effect of the dead weight of the push rod (s) on the locking process is reduced, in that at best the loads caused by the gravity cancel each other out. If the kinematics of the locking device is selected in such a way that when the door is locked, the two push rods are moved away from one another, securing bolts are expediently also provided at their ends, which in corresponding recesses in the lintel or the Intervene in the threshold.

Of course, the position of the push rods can vary - in the middle or off-center; if the door wing has a letter slot and / or "spy", the push rods are to be arranged appropriately offset.

The actuation openings in the metal tubes are preferably narrow elongated holes, with exactly one elongated hole being assigned to each securing bolt. By keeping the actuation openings as small as possible in this way, unnecessary weakening of the metal pipes is avoided. avoided. In this case, the actuating openings are penetrated by a pin which is embedded in the securing bolt and on which a link acts in an articulated manner. However, the actuating openings can also be designed such that the actuating members (for example rods, ropes, Bowden cables, levers) for both securing bolts of each tube pass through a common actuating opening.

The metal tubes are preferably clamped in the door leaf by means of clamping nuts embedded in the door frieze. For this purpose, the metal tubes expediently have external threads at both ends, onto which the clamping nuts having the corresponding internal threads are screwed. The door friezes have depressions to accommodate the clamping nuts.

At various points in the locking device or the actuating mechanism for the securing bolts, spring elements can be provided which support the locking and unlocking process. In general, the spring elements will be arranged in such a way that they Preload the safety bolt in the unlocked position.

An exemplary embodiment of the invention is explained in more detail below with reference to the drawing. It shows

1 is a partially sectioned view of a door according to the invention in the unlocked position,

2 the door according to FIG. 1 in the latch position,

3 shows the detail "A" according to FIG. 2 with the cover removed,

4 shows a horizontal section along the line IV-IV in FIG. 2 through an embodiment of the transition area from door leaf to frame that is alternative to that in FIGS. 1 to 3, in an enlarged view,

5 shows a view according to FIG. 3 of a further embodiment and FIG. 6 shows a section along line VI-VI in FIG. 5.

The door according to FIGS. 1 and 2 comprises a frame 1 and a wing 2. The latter is in a known manner on the frame by means of hinges (not shown) on the right side -li¬

struck. Accordingly, the door wing 2 has on the left side a lock 3, which is constructed in a conventional manner and is arranged on the wing. The door leaf 2 is made in a lightweight construction, i.e. it is constructed from a frieze 4, a filling 5 inserted therein and coatings 6 applied on both sides. In this respect, the door according to FIGS. 1 and 2 corresponds to the conventional design of doors.

Seven metal tubes 7 are embedded in the door leaf 2. They extend continuously from the left frieze 4a to the right frieze 4b; the tubes 7 are flush with the outer circumference of the wing 2, ie flat with the outer edges of the friezes 4a and 4b. Two securing bolts 8 are arranged in each tube 7. They can be moved inside the tubes 7. The frame 1 has seven blind bores 9 in each of its two vertical sections. These are arranged in the extension of the tubes 7 of the wing and have a diameter such that the securing bolts can enter them. The blind bores 9 serve as receptacles for the securing bolts 8 in the locking position (FIG. 2). Each tube 7 has two elongated holes 10 (FIG. 3), the length of which corresponds to the displacement of the securing bolts 8 in the tubes 7 between the unlocked position (FIG. 1) and the locking position (FIG. 2). A pin 11 inserted into each securing bolt 8 passes through the elongated holes 10. A link 12 is attached to each pin 11 at its end protruding from the tube 7. The two links assigned to each pair of securing bolts 8 are free Ends, ie coupled to the pin 11 opposite their respective connection point and jointly struck jointly on the pin 13. The pin 13 is in turn inserted into the push rod 14 and protrudes from it in the direction of the tube 7, so that the links 12 of each pair of safety bolts 8 move in planes which lie between the tube 7 and the push rod 14 lie.

1 and 2 has two push rods 14a, 14b, of which the upper push rod 14a is used to actuate the safety bolts arranged in the upper three tubes 7 and the lower push rod 14b is used to actuate the bolts arranged in the four lower tubes 7 Safety bolt. The Handlebars 12 are struck on the upper push rod 14a on pins 13 which are below the respective tube 7; on the lower push rod 14b, the links 12 are articulated to pins 13 which lie above the corresponding pipes 7. In this way it is achieved that the two push rods 14a, 14b perform opposite movements when locking or unlocking. The respective inner end of the two push rods 14a and 14b is assigned to a common lock 15 which actuates the two push rods in opposite manner in a manner known per se. The upper end of the upper push rod 14a and the lower end of the lower push rod 14b are designed as additional securing bolts; they engage in the latch position (FIG. 2) in corresponding receptacles in the lintel 16 or in the threshold 17.

In order to accommodate the entire locking mechanism, ie the lock 15, the push rods 14a and 14b and the handlebar 12, in the embodiment according to FIGS. 1 to 3, a recess is made in the door leaf which is covered by a cover 18 (FIG. 1 and 2) is disguised. With the cover 18 removed (FIG. 3), the tubes 7 are accordingly completely exposed in the region of the recess. A alternative arrangement and configuration of the actuating mechanism are shown in FIGS. 5 and 6 described below.

4, which shows the detail of a horizontal section through the frame 1 and the door leaf 2, the design of the components connected to the metal tubes 7 and the securing bolts 8 can be seen in detail. A double-stepped bore 19 is introduced into the front of the door frieze 4a; it serves to receive the metal tube 7 and the clamping nut 20. Accordingly, the smallest diameter corresponds to the bore

19 the outer diameter of the metal tube 7, the average diameter of the stepped bore 19 corresponds to the outer diameter of the shaft of the clamping nut 20, and the largest diameter of the stepped bore 19 corresponds to the outer diameter of the collar 21 of the clamping nut

20 match. The clamping nut 20 has an internal thread which is screwed to the external thread provided on the end of the metal tube 7. A corresponding arrangement is provided at the opposite end of the tube 7. As a result, the tube 7 is clamped in the door leaf 2. Axial bores are provided in the collar 21 of the clamping nut the clamping nut 20 can be tightened by means of a tenon key.

A bushing 22 is let into the frame 1, into which the securing bolt 8 moves when the door is locked. The sleeve 22 is made of a metallic material. In the case of a frame 1 made of wood, it prevents it from breaking out in the area of the receptacles for the securing bolts.

In the embodiment of the door according to the invention shown in FIGS. 5 and 6, the actuating mechanism for the safety bolts is arranged on the outside of the door (and not in a recess made in the door as in the embodiment described above). Of course, also in the embodiment according to FIGS. 5 and 6 the actuating mechanism is usually covered by a cover (cf. cover 18 according to FIGS. 1 and 2), which is not shown in the drawing, however.

The double-sided coatings 6a, 6b and a filling 5 arranged therebetween is crossed by metal tubes 7 in the manner described above. In the metal tubes 7 two safety bolts 8 are each longitudinal slidably guided. In the locking bolt 8, the pin 11 are embedded, which are guided in the two elongated holes 10 of each tube 7. To this extent, the embodiment according to FIGS. 5 and 6 corresponds to the embodiment described above. Corresponding to the elongated holes 10 of the tube, elongated holes 23 are introduced into the door panel 5 and the coating 6a arranged on the inside of the door. They are also penetrated by the pin 11. A vertically aligned, U-shaped rail 24 rests on the inner coating 6a. It is held by cylinder head screws 25, two cylinder head screws being provided at the height of each tube 7. For this purpose, a nut 27 provided with two threaded bores 26 is introduced into each tube 7, into which the screws 25 are screwed. As a result, the rail 24 is fixed at the same time as each tube 27 is secured against displacement and twisting.

The push rod 14 is guided between two heads 28 of the cylinder head screws 25. The pins 13 let into the push rod 14 and against which the links 12 are attached protrude outward from the push rod 14, ie in a direction away from Pipe 7. The links 12 coupling the pins 11 and 13 are thus - in contrast to the embodiment according to FIGS. 1 to 3 - outside, ie the push rod 14 is arranged between the links 12 and the pipe 7.
