Description

The Invention relates to a device for opening folding doors according to the preamble of Claim 1 or 2.

Such Devices or tools are included for the legal opening of doors that have accidentally fallen into the "lock Multiple fold provided. They are required if short term no key available for opening as intended is, or the locking mechanism may not be opened for any other reason. Locked to open Doors are such tools are not suitable.

A tool in the form of a wire coil for opening double rebate doors is already out of the DE 100 26 577 A1 known. The disadvantage of this tool is that, due to the asymmetrical fold geometry, good tact is required when using it. Another disadvantage is that due to its necessary stability to open the door, damage in the form of scratches on the door frame is occasionally unavoidable.

Out DE G 84 09 216 is a door latch for opening Doors with known as a single fold, made from an approximately one millimeter is made of flat sheet metal or a hard plastic and has a "Z" shape. However, it is suitable not to open from such doors that have multiple folds. For doors with two or more folds namely decreases the scope for insertion a suitable tool in the space between the door leaf and Frame opposite a rebate door dramatically. The higher the number of folds is the more difficult it is to insert and especially moving the tool in the space.

On concerns another problem with a narrow, very difficult to access space dimensionally stable single rebate doors, such as. Front doors made of metal and the like. The opening tools known to date are also used in such doors often very difficult to use and often leave damage at the door and / or the door frame.

Task and Advantages of the invention

The The invention is therefore based on the object of a tool for as far as possible easy and damage - free opening of Folding doors to disposal to deliver.

This Task is based on a device for opening Folding doors according to the preamble of claim 1 solved in that an insertion section the device from a thin and flat Material is designed, and at one end by existing bends or prepared hinge-like locations at least four bends are trained or are able to be trained, who are in their form during a Change insertion process to let.

By the formation of four bends, it is possible to make a double rebate door according to the invention to open, that the device with the end having the bends into an enlarged space between door leaf and frame inserted and then in this direction the snapped lock latch is moved until the door opens. The sheet thickness of the flat material is preferably about 0.5 millimeters, but can also be thinner, e.g. 0.35 millimeters or slightly thicker e.g. B. 1 millimeter.

This Bends between adjacent surface areas of the insertion section can by a form effect with a lasting effect on the material, for example by bending. In this case the device preformed. However, it is also possible that the insertion section in the area of the bends is flat and is designed to be movable, and only when it is inserted into the fold area takes the appropriate shape, i.e. is angled. Also conceivable is a combination of prefabricated bends and hinge-like trained sections, for example to achieve even greater flexibility.

The However, the invention is not based on a device with four bends limited. It can rather, more or fewer bends can also be formed, wherein their total number, preferably the number of folds of one to be opened Multiple Falztür equivalent. This device can of course also to open of single rebate doors be used.

On Another essential aspect of the invention provides a device to open of rebate doors with an insertion section made of a flat, thin material on which Inserting a traction device is arranged such that exercise a train on the traction part of the insertion section, in particular its front area is pressed against the lock latch, that it opens.

The The insertion section can optionally also be preformed without it Bends or prepared hinge-like places his. However, it is advantageously provided with such.

Depending on the situation in the Door gap a direct or indirect influence on the lock latch possible. Either the traction device itself or a section of the insertion section that can be influenced by the traction device, preferably this is the area before the first bend, can act on the lock latch so that it is pushed back until the door lock opens. For this purpose, the traction means is preferably connectable to the front portion of the insertion section or arranged on it, for example suspended, knotted with it or fastened to it in a correspondingly different way. By using a traction device, the device can be formed with a very flexible and thin material in the insertion area, the material thickness of which may also be significantly below the values given above.

to better handling of the device or the traction device can A grip means may also be provided. This is a good dosing Pulling action to open the door possible. As materials for the traction means are suitable for example wires, cords, tapes and the like.

The Using an additional Traction means is a matter of course not to a double angled or angled embodiment limited, but is rather on all sorts Forms of such devices transferable, especially one with four bends.

The Enlargement of the Space between the door leaf and frame is preferably at the lower ends in the bottom area carried out. This Site is easily accessible and over the leverage effect due to the distance to the snapped lock latch is the easiest way to intervene here without damaging the door.

by virtue of the elastic properties of the device or of the manufacture the material used in the device, the bends can at least partly deformed so that it is easier to insert them the device in the enlarged space is effected.

In a preferred embodiment the insertion section has at least partially an elastic Material with restoring forces, the one to introduce counteract the required deformation of the bends and at least partially returns them to their folded form. This has the advantage that the one having the bends Introductory section if possible has the same shape as the free space between the door leaf and Frame. This results in one if possible low resistance effect when moving the device in the gap in the direction of the snapped lock latch. This is particularly important because as the number increases from folds to door and frame the one to be overcome Resistance increases drastically when moving the device. These disadvantages can minimized by the restoring forces present in the elastic material and ideally even be eliminated.

In a special embodiment can the bends even temporarily flattened so that there is a narrow space between the door leaf and Frame is already sufficient to fit the device according to the invention Way to introduce. The restoring forces are so big that them this temporary At least partially remove the deformation.

Furthermore, it is preferred that the insertion section is designed such that it has good sliding properties. Has advantageously the material has a smooth surface, possibly with lubricating properties. This is the frictional resistance when pushing up in the space between the door leaf and Frame reduced. This is particularly advantageous if additional door seals are used are arranged in this space.

to it is advantageous to further improve the sliding properties an additional Apply lubricant to the corresponding surfaces of the device. For example, a silicone spray can be used because this has very good sliding properties, is colorless and also positive Influences sealing materials.

Especially It is advantageous if the geometry of the at least four bends is adapted to the rebate geometry of a multiple rebate door. For a variety In applications, this is relatively easy because there are standard dimensions for rebate doors. For folding doors that of these standard dimensions can deviate the geometries of the bends are modified accordingly, so that the device in turn is given as well as possible Space is fitted: Ideally, the bends aligned parallel to each other according to the edges in the folds.

Tools or devices that have generous curves in the bends require naturally one greater scope in the space between the door leaf and frame and therefore tend to with increasing rounding of the edges Clamping. Again and again it was found that such devices or tools even in the material of the door or the door frame, in usually in wood, like a knife, and this solid damaged. These disadvantages are caused by an angular configuration of the bends reduced.

As Assistance in pushing back the snapped Lock latch has an area of the insertion section, which is inserted in the Condition can get to the lock latch, at least one slope, whose edge when pushing up the device on the lower edge the beveled back the snapped lock latch slips along and this backwards towards the castle urges and so the locking function picks.

advantageously, will open the jamming of the locking mechanism due to the tension in the door in the door frame loosened. This can be done by pulling or pushing the lever handle.

There it occasionally happens that when trying to open the door the Device when pulling up the position of the snapped lock latch slips away another, to the first slope preferably a mirrored second slope on the device, so the tool snapped from a position above the Lock latch can also be moved down, as well the function just described for opening the door is effected.

In a particularly preferred embodiment is additional to the first and / or second slope just described further slope arranged, which preferably adjoins the first or second slope and one flatter angle with respect to the longitudinal axis of the device. Through this further slant is the Device can be used more universally. On the one hand, the release effect When opening the snapped lock latch can be supported, on the other hand it can even differently positioned lock latches easier to reach and opened with it become.

to easier handling of the device, this has a handle, which is preferably arranged parallel to the course of the bends is. This allows them to be gripped and held well, which in particular with a flat, thin Material causes significant advantages in handling. This alignment of the handle accommodates the handling of the tool, so that on the one hand, with more feeling and on the other hand also with larger, targeted usable effort and thus better power transmission can be worked on the snapped lock latch.

drawings

On embodiment the invention is illustrated in the drawings and is under Reference to this in more detail below explained.

It demonstrate:

1 an oblique, perspective view of a device for opening multiple rebate doors;

2 is a schematic representation of the handling of the device 1 when inserted into a door gap;

3 also a schematic representation of the handling of the device according to the 1 and 2 when opening a snapped lock latch;

4 a sectional view through a door, a frame and the device according to the invention in the amount of a snapped lock latch;

5 and 6 a further embodiment of the device with an additionally arranged traction device in plan view and side view.

The 1 shows the device according to the invention 1 for opening multiple rebate doors. It has an insertion section 2 on where four bends 3 to 6 are trained. At this insertion section 2 another section closes 7 at which the insertion section 2 opposite end a handle 8th is trained.

At the end of the device where the four bends 3 to 6 are formed, two bevels on the front 9 . 10 educated. To open a snapped lock latch they are pushed against the lower or upper oblique edge until the lock latch is pushed back and the door opens.

For a more universal design of the device are in addition to the two slopes 9 . 10 two more slopes 11 . 12 formed on the area facing the lock latch, the two outer edges in the direction of the second bend 4 limit. This further improves the effect of the device when the lock latch is opened. This shape allows the device to be rotated to a certain extent in the space between the door leaf and frame around a pivot point located in its surface, so that the opening of the snap-in lock latch is thereby supported.

A longitudinal axis is the reference line for the device which is approximately rectangular in plan view 13 located. The end face is approximately at right angles to this longitudinal axis and has the bevels described above 9 to 12 on. Accordingly, the angles formed in these areas give way to the longitudinal axis 13 from the original 90 degrees.

The 2 shows a schematic representation of a handling of the device according to the 1 when inserted into an enlarged door gap 16 between door 14 and frame 15 in the foot area. The arrow 17 shows the direction of insertion of the device 1 in the door crack 16 ,

The 3 again shows the device 1 , arranged in the area of the door lock between the door 14 and frame 15 : By moving the device 1 in one of the two directions of the arrow 18 the snap latch can be opened according to the invention. The arrow 18 therefore has two arrow directions, since it occasionally occurs that the device 1 slips over the locking mechanism of the snapped lock latch and the door remains closed. Then it is necessary to use the device 1 back in the opposite direction, i.e. pulling back or pushing downwards, whereby it is also possible to unlock the snapped lock latch.

The 4 shows a sectional view through a door 14 , a frame 15 and the device according to the invention 1 at the level of the snapped lock latch 19 , The insertion section 2 with the bend 3 to 6 is in the door gap 16 between door 14 and frame 15 inserted. The section faces away from the door gap 7 with the handle attached to it 8th shown. In the front area of the device, i.e. at the end at which the bend 3 is formed, that is in the striking plate 20 the frame 1.5 snapped lock latch 19 shown. In this position of the device 1 in the door gap 16 lie the slope 9 the device 1 and the sloping edge 21 the lock trap 19 to each other. By moving the device 1 against the lock latch 19 Two sloping edges run along each other, causing the lock latch to go in the direction of the arrow 22 is pushed back until the door 14 is unlocked.

With the positions 23 and 24 In addition, the two seals of the double-frame door are shown, which, as a further complication when opening an unintentionally snapped lock latch, prevent easy opening.

The 5 and 6 show a further embodiment of a device for opening folding doors in plan view ( 5 ) and in side view ( 6 ). In addition to the features already described, here is a traction device 25 shown, which is arranged approximately in the middle in the longitudinal direction along the device.

This traction device 25 is in the area before the first bend 3 connected to the flat material in such a way that under the action of a pull on the traction means this area against the handle 8th is pulled. The front area bends in the bend 3 From or the already angled area inserted between the door and frame is supported by the action of the train in its bending. In addition, this area can also be parallel to the bend, if necessary 3 towards the lap trap 19 bend, as can be seen from the insertion section shown in dashed lines.

This effect is analogous in the 6 recognizable. The traction device is in a loose arrangement through the guides 28 along the in 5 line shown to the handle and further through this by means of the guide arranged therein 27 , The end of the traction device located at this point 25 is like this with the grip means 26 connected that by pulling on the grip means 26 the desired pull effect can be transferred to the device. The guides 27 and 28 are helpful, but they are not absolutely necessary to achieve the supportive effect when opening the door.

The action on the lock latch 19 can thus both over the front section of the insertion area 2 take place before the bending 3 is located, as well as possibly directly through the traction means 25 if this is cheap on the lock latch 19 can be arranged or if necessary caught when moving the device.

The The invention is shown here by way of example using a double-frame door, however, it is not the solution limited to such a problem. Rather, a larger number can also be used of folds in a door be arranged, which are opened by the device according to the invention can. Accordingly, the device according to the invention accordingly more angles.
