Description

The invention relates to a swing door arrangement in which with pivot bearings attached to the door frame in a door frame opening at least one door leaf is rotatably arranged, the door frame consisting of a door lintel and one to it parallel door sill and from mutually parallel door posts, of which at least one is on the stop side of the door leaf is arranged, and wherein the door leaf is mutually parallel upper and lower door leaf transverse frame legs, a stop-side frame leg and a lock-side frame leg parallel to this which are firmly connected to one another.

Centrally attached or hinged pivoting or swing door arrangements with a non-changeable axis of rotation (center-hung pivot door assemblies), whether with one or more door leaves, are widespread, but are used most commonly used in commercial buildings. Such door leaves are usually made of a metal, for example made of aluminum, have glass panes and are

pivotally accommodated in a metal frame, which consists of posts, lintels and Threshold exists. Such door leaves should meet several requirements, namely they should be pleasing, aesthetic Appearance, they should be constructed in such a way that they can be forcibly attempted by people when the door is locked to penetrate the building, resist, they should be weatherproof and they should be safe in use. With regard to the latter point, the door should be designed so that people, and especially children, can not hands or feet either between the door frame jamb and the adjacent door leaf leg or when in a single one Door frame two door leaves are hung between the door leaf legs on the lock side, or if you do, do not suffer serious injury as a result. This safety factor is of particular importance in Commercial buildings where the doors are used by a large number of people.

Try to reconcile these requirements, and especially an adequate mechanical Resistance to forcible breaking, together with weather resistance and security in use, do not have to be created led to completely satisfactory results. Because of security needs and because of the desire to protect against the effects of the weather to protect, therefore leave doors currently in use full security protection in more or miss it to a lesser extent. For example, the use of elastic materials in the field of Stop and lock side door wing leg avoided, as such material from people who are through the Trying to gain access to the door by force can usually be taken away without further ado. Besides, it was difficult using such elastic means to seal doors against the effects of the weather, since they are elastic Materials wear out quickly if they come into contact with a hard surface. 403881/0939

The invention is based on the object of a swing door arrangement to create the type described above, in which the risk of injury for people trapped in the door Finger is essentially excluded and which is weatherproof and burglar-proof at the same time.

The solution to this problem has led to a proposal which, in the case of a swing door arrangement, is the one mentioned at the beginning This type provides that a relatively narrow approach is attached to the hinge-side door post, which is extends over substantially the entire length of the door post and protrudes from this into the door frame opening, that at a small distance from this door post approach a stop-side door leaf frame leg of arched Cross-sectional shape is arranged, and that the gap between the stop-side door post and the stop-side The door leaf frame leg is covered by elastic weather protection at least when the door is closed, wherein said gap is always smaller than the thickness of a human finger and the approach near the stop-side Door leaf frame leg is sufficiently narrow so that this spatially narrow arrangement can be hooked in and unhooked of the door leaf on the pivot bearings, while the approach remains attached to the hinge-side door post, not prevented.

Preferably, the surface of the door post attachment is that towards the door leaf frame limb, which is arcuate in cross section, on the stop side has, substantially concave and arranged concentrically to the latter.

The door leaf also preferably has an elastic edge protector that is significantly wider than the thickness human finger and is attached to the outer edge of the lock-side door leaf frame leg and is essentially extends over its entire length. Are on the door frame

409881/0939

- f- 44 963

two door leaves hinged, only one of them needs to be provided with such an elastic edge protection in order to ensure that fingers cannot be pinched between the door leaves and injured. With advantage lies When the door is closed, weather protection is applied to essentially the entire length of the edge protection.

The invention further provides improved handle strips for pressing the door leaf or a central transverse frieze with a recessed pull handle, which is designed so that a lock cylinder can be installed completely sunk, so that its exposed face is flush with the surface of the handle bar, or with one of the recessed pull handle enclosing shield plate, which allows the removal of the lock cylinder, with the intention of itself Gaining access by force is more difficult.

The subject matter of the invention also results from the claims.

The invention is described below with reference to schematic drawings several embodiments explained with further details. In the drawing shows:

Pig. 1 shows in elevation a single-leaf swing door arrangement 20 which is hinged centrally or has a stationary axis of rotation (single center-hung door assembly). The associated door leaf is composed of an upper frame leg 21, a parallel lower frame leg 22, a cross-sectionally arcuate, essentially cylindrical stop-side frame leg 23 and a lock-side frame leg 24, all of which are firmly connected to one another. On the essentially parallel frame legs / ln ⁿ opposite sides of the door leaf, the handle strips 25a and 25, which are described in more detail below and which extend from one to the other, are attached

409881/0939

- 4 - 44 963

Frame legs extend. In the area delimited between the horizontally and vertically running frame legs one or more filling parts are arranged, for example a transparent glass pane 26.

The door leaf is rotatably attached to a door frame which is composed of a door lintel 27, a door sill 30 parallel to it, a door post 28 on the hinge side and a stop post 29 parallel to it.
The means of attaching the door leaves to pivot bearings
and their local position can be designed or selected in any conventional manner, but preferably meet the manufacturer's specifications for concealed or recessed ceiling door closers, floor door stays and ceiling door closers mounted on the wall. An attachment in connection with a concealed ceiling door closer is shown in FIGS. 6 and 7, for example.

An essential feature of the invention is that the stop-side frame leg is not directly on
door post 28 on the stop side. A narrow post attachment protrudes from the stop-side door post by a noticeable amount and extends to just before the stop-side frame leg 23. The post attachment 31 holds the stop-side frame leg far enough from the door post 28, at least by an amount as large as the thickness of an adult's finger , so that no fingers can be squeezed by the rolling action of the frame leg when opening and closing the door leaf that were stuck between the hinge-side door post and the hinge-side frame leg as a result of carelessness. The distance between the post attachment 31 and the frame leg 23 on the stop side is also too small for fingers to be inserted between them. The relationship between the frame leg and the door jamb is thus of the type
that it is extremely difficult even for a young child, though

4Ü9881 / 0939

/ 7

44 963

is not impossible to "open or close the Pinch fingers and injure the door leaf.

Because the post attachment 31 »based on the diameter of the stop-side frame leg, in the direction from front to back has a small thickness and thus not a very encloses large circumferential length of the frame leg, the door leaf can be when the post approach on the post in position is brought, insert in the door frame or remove from it without the jamb approach. This aspect ratio between the door post attachment and the hinge-side frame leg also ensures that between them as a result of rolling effect when opening or closing the door leaf fingers are not pinched and can be crushed.

In Fig. 2, the arcuate cross-sectional shape of the im substantially cylindrical frame leg 23 on the stop side is shown. In this figure it can also be seen in what way to the door frame opening facing edges 29a on the stop post 29 and edges 28b on the stop side Door posts 28 are preferably rounded to avoid any possibility of hands or other body parts being pinched between To injure the door leaf and the door frame, to reduce it even more to the lowest possible level.

FIG. 3 shows, in conjunction with FIG. 4, a view on an enlarged scale Scale, the frame legs shown in Fig. 2 to illustrate the / vSr ^ cnrSfigen with which the Handle strips 25a and 25b for pressing the door leaf are attached to this, and those in which the cylinder locks are included and prevent that this can be expanded by people who are unauthorized Want to gain access to the building. In Fig. 3, the approach 31 of the hinge-side door post is in the preferred one Design shown. This preferably off

A09881 / 0939

p 44 963

Metal-made door jamb approach is received in rods 32 and held in these with tongues 33. The attachment of the approach 31 on the door post 28 takes place before striking of the door leaf by inserting the tongues 33 into the grooves 32. As a result, the door post attachment 31 is with the door post 28 is locked, and there is no space between the two components for any tool to break into the door could be introduced.

The outer surface 34 of the door jamb extension 31 preferably has a substantially arcuate-concave shape, with the arcuate shape of the rounded stop-side Frame leg 23 is substantially concentric. In addition, the surface 34 has a central, recessed one Section 34a, which extends along the surface 34 and in which a weather strip 35 is received. In a (not shown) modified embodiment, one or more weather strips are instead of the door post approach on the stop-side door leaf frame leg 23 is provided. In order to offer the best possible protection against the weather, the elastic weather strip 35 covers the very narrow gap between the hinge-side frame leg and the approach on the hinge-side door post and extends over substantially the entire length of the door jamb extension 31. In addition, it is due to the in Fig. 3 arrangement shown in such a way that it is effective when adjusting the door leaf from the completely closed in the fully open position, the passage of air or water through the gap is reduced.

The stop-side door leaf frame leg 23 also has an opening on each side of the door leaf into which Let one end of the grip strips 25 be inserted in each case. The dimensions of the handle strips 25 and the openings for this in the Door leaf frame legs 23 are chosen so that the handle strips as soon as they are in the manner described below

409881/0939

- <er ~ 44 963

are attached to the lock-side door leaf frame leg 24, also in the openings of the stop-side frame leg 23 are securely wedged.

In that of the cross frame legs 21 and 22 and the frame legs 23 and 24 of the door leaf formed opening a pane of glass 26 is attached, with conventional Glass holders 36, which are usually made of aluminum, and elastic sealing strips 37 »the fingers to seal the glass against the passage of air or water on the pane edges *

As previously mentioned, the thickness of the door jamb extension is 31 limited upwards. This maximum thickness allows the door leaf to be attached to the door lintel and door threshold mounted swivel bearings. Please refer to the description below. This makes it possible to open the door leaf to be posted or removed without the door jamb extension 31 having to be removed or interfered with. This in turn allows the attachment to be locked on the door post 28 in order to make the door arrangement even more burglar-proof do. It is clear that if the door jamb approach is too thick 31 »measured in the direction from front to back or from the inside to the outside of the door leaf, So if its concave surface 34 extends over a very large circumferential length of the cylindrical stop-side Door leaf frame leg 23 extends, it is difficult, if not impossible, the door leaf on the pivot bearings to or knock off, especially because the gap between the surface 34 of the door jamb extension 31 and the cylindrical surface of the stop-side frame leg 23 is kept noticeably smaller than the thickness of human fingers to prevent children or other people from getting their fingers caught between these components. On the other hand, the width of the door post approach, between the door post 28 and the hinge-side door leaf frame leg 23,

409881/0939

/ 10

44 963

Much larger than the maximum thickness of a human finger to be trapped when opening or closing the door of fingers between the door post and the hinged door leaf frame leg to prevent by rolling effect.

As can be seen in FIG. 4, a cross-section is shown at the outer end of the door leaf frame leg 24 on the lock side curved, elastic edge protection 38 attached. Its width, measured from the door leaf frame leg to to the door post, exceeds the thickness of a human finger, so that even an adult with the door closed can grasp the door leaf edge with your hand and yet, due to the elasticity of the edge protection, jamming protrudes intact between the door leaf and the door post. The edge protection 38 is with the frame leg 24 with the help of Shoulders 39, which come to rest on the end of the frame leg 24, and locked by tongues 40, which are in holding grooves 41 set, which extend over the length of the lock-side frame leg 24. This groove and Spring connection prevents the edge protection from being pulled out 38, since this can only be done by being pushed into the grooves either from the lower or from the upper end of the frame leg 24 can be brought into position on this or removed from it.

In the stop door post or door post on the lock side inserted and locked with this is a weather strip arrangement 100, the outer surface of which is essentially the same in area flush with the outer surface of the door post 29. Arms 101 extending from the outer surface snap to lips on the door post 29. As can be seen most clearly in FIG. 11, protrude from the outer edge of the weather strip arrangement into the door frame opening elastic weather strips 103 into the gap between the edge protection 38 and the Bridge door post 29. In the preferred embodiment, the edge protection is with a lengthways

409881/0939 / H

~ 44 963

extending web 104 provided, which is arranged approximately in the middle of the edge protection, so that it is in the Closed position of the Turflugis in the space between the Weather strips 103 ″ arranged in pairs is located. This further ensures adequate weatherproofing. Weather strip supports 105 are displaceable in weather strip receiving grooves 106 in the weather strip arrangement 100 recorded.

The elastic edge protection 38 and the filled in by it, considerable space between the lock-side frame leg 24 and the adjacent door post make it impractical to provide a door latch that extends from the door leaf frame leg to the door jamb. The closing the door is made with bolts that extend lengthways from the frame leg on the lock side into the door lintel 27 and penetrate the door sill 30. In the frame leg on the lock side there is a conventionally designed device housed for advancing and retracting such bolts, which are inserted into cylinder locks 44 Lets press keys. Such a door lock makes the door at least as secure against unauthorized opening like conventional doors.

The handle strip 25a is attached to the inside of the door leaf 20 and has a screw hole 41a and a stepped one Provided receiving opening 42a for a cylinder lock. The handle strip 25b attached to the outside of the door leaf

has at its corresponding end a blind threaded hole 41b and a stepped receiving opening 42b for a cylinder lock on. For attaching the handle strips to the door leaf frame leg on the lock side 24, a threaded bolt 43 is used, which has a head 43 a and a thread 45. The head 43a is selected in its dimensions so that it fits into the stepped opening 41a. The cylinder locks 44 have cylinders 44a, which is inserted into the locking device inside the

409881/0 939/12

44 963

Frame legs are screwed in, and flanges on that come to rest on the shoulders of the recesses 42a and 42b. In this way they contribute to the fastening of the Handle strips on the door leaf frame leg. Let it be up Fig. 5 referenced, in which the above-described details can be seen most clearly. The grip strips 25a and 25b are inserted into the openings in the frame leg on the stop side 23 inserted and then brought into position so that their openings 41a and 41b and 42a and 42b in Coverage with corresponding openings 47a and 47b or 48a and 48b are located in the frame leg 24 on the lock side. Of the The threaded bolt 43 is then inserted into the recess 41a and into the openings 47a and 47b in the frame leg on the lock side 24 and screwed with its threaded end into the matching threaded hole 41b in the grip strip 25b. In Similarly, the cylinders 44a of the cylinder locks 44 are screwed in until they are in the locking device take their correct position. Since the assembly or handle strip 25a is located on the inside of the door leaf, none of the screws, bolts or other fasteners are accessible from the outside of the door leaf. The outwardly facing end face of the cylinder locks essentially closes with the outer face of the grip strips so that it is impossible for people who want to gain unauthorized access through the door, Access the cylinder locks with a tool and unscrew it from the locking device.

In Fig. 6 a concealed or concealed ceiling door closer 51 is shown, with which the door leaf on the door frame is posted or attached. Such a door closer is attached to the door lintel 27 in the usual manner and has an axis of rotation 52. For connecting the upper cross frame 21 of the door leaf frame leg on the hinge side 23 is an angle fitting or L-shaped door rail 53 On the upper transverse frame leg 21 of the door leaf, an upper fork 55 is attached with screws 54, the

Fork legs fit together with the axis of rotation 52. To the A cap 56 is screwed onto the ends of the fork legs, so that an enclosure is obtained which completely surrounds the axis of rotation 52 surrounds. In order to cover this opening in the hinged door wings 1 frame leg 23 is on the frame leg 23 a cover plate 57 is attached with screws 58.

Fig. 7 shows in a partially cut-away representation the inclusion of the door leaf on the lower pivot bearing. The drawing shows an axis of rotation that cannot be changed in position hinged swing doors usual lower pivot bearing arrangement 59 with a lower pivot bearing 60 and a door leaf frame leg angle fitting 61. The task of the angle fitting 61 is the connection of the stop-side end the door threshold 30 with the door post 28. At the lower web of the door leaf transverse frame leg 22, an angle fitting or L-shaped door rail 63 is attached, with which the transverse frame leg is firmly connected to the frame leg 23. A lower fork 64 is attached to the web 62 with screws 65, the fork legs encompass the lower pivot bearing 60 at a distance. On the frame leg 23 is one with screws 68 Cover plate 66 fastened with holding arm 67.

Fig. 8, 9 and 10 show a modified two-leaf embodiment according to the invention, in which two swing door leaves attached centrally or with a stationary axis of rotation are arranged in a single door frame. Each of the! Door leaves has an upper transverse frame leg 71, which runs parallel to a lower transverse frame leg 72, which is fixed to an arcuate cross-section frame limb 73 on the stop side, which in turn is parallel to a frame limb 74 on the lock side is aligned. In this embodiment, the door leaves are provided with an intermediate transverse frieze 75. In openings, which are formed by the frame legs and the transverse frieze, glass panes 76 are inserted. The door frame is in

Usually from a door lintel 77, a door threshold and hinge-side door post 78 assembled, wherein the latter are provided with door post extensions 78a of the type described above. The intermediate transverse frieze also shows a recessed or recessed pull handle 79 which is fitted into a recess in the transverse frieze 75. For this reference is made to the following detailed description. In this example, the hinged door wings are 1 frame legs and door posts formed in the same way as in connection with the exemplary embodiment Pig. 1 to 7.

From the opposite door leaf frame legs on the lock side 74 one is provided with an extension 80, which can be made of an elastic material can. The frame limb 74 of the other door leaf has an elastic protection 82 which is arcuate in cross section with a centrally arranged longitudinal web 82a. on. The width of the guard 82 exceeds the thickness of human Fingers so that they cannot be injured if they are caught between closing door leaves. On the outer edge the frame leg extension 80 is an elastic one Attached weather strip 81, which is chosen in its dimensions so that it bridges the gap between the frame leg extension 80 and the elastic edge protection 82 bridged. For inserting the glass panes 76 into the frame openings the door leaves are conventional glass pane holders 83 and elastic sealing strips 84 are used.

The recessed or recessed pull handle 79 has side walls 85 and a rounded arm 86 that has an opening 87 limit, in which one can intervene with the hand to adjust the door leaf. To close the chamber or Opening 87 above and below are on the pull handle 79 with screws
