Description

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

Such Devices or tools are used for the legal opening of unintentionally "fallen" doors Multiple fold provided. They are required if short term no key available for use according to opening is, or the locking mechanism if necessary, can not be opened for any other reason. To open locked Doors are such tools are not suitable.

A tool in the form of a wire helix for opening double seam doors is already out of the DE 100 26 577 A1 known. This tool has the disadvantage that due to asymmetrically constructed folding geometries a good instinct is required in its application. Another disadvantage is that due to its necessary stability to open the door occasionally damage in the form of scratches on the door frame are unavoidable.

From the DE 84 09 216 U1 Door latch is known for opening doors with a single fold, which is made of a sheet metal about one millimeter or a hard plastic and has a "Z" shape. However, it is not suitable for opening such doors having multiple folds. In fact, in the case of doors with two or more folds, the scope for introducing a suitable tool into the space between the door leaf and the frame is drastically reduced compared to a single-seam door. The higher the number of folds, the harder the insertion and above all the movement of the tool in the space.

This describes the DE 100 53 527 A1 an opening tool, which consists of a relatively strong plastic film and whose front edge is stiffened by a protruding in width steel wire, which is intended to be drawn after engaging behind the door latch by the plastic film to open the door against it. However, practice has shown that even the use of this tool does not provide particularly satisfactory results.

One Another problem with narrow, very difficult to access gap concerns dimensionally stable single-fold doors, such as. Front doors made of metal and the like. Even with such doors, the previously known opening tools often very difficult to use and often leave damage at the door and / or the door frame.

Purpose and advantages of the invention

Of the Invention is therefore the object of a tool as possible easy and damage-free opening of Folding doors to disposal to deliver.

These Task is based on a device for opening Folding doors solved according to the preamble of claim 1, characterized in that a plug-in section the device of a thin and flat Material is designed, at which insertion a traction means is arranged such that by exercising a train on the traction means a part of the insertion section, in particular its front area, pressed against the latch it will open.

By Depending on the situation in the door gap, the traction device is a direct or indirect one Impact on the latch possible. So either that Traction means itself or an influenceable by the traction means section the insertion portion, preferably this is the area in front of the first bend, so act on the lock latch that this is so pushed back far, until the door lock opens.

The For this purpose, traction means is preferably in the front region of the insertion section connectable to this, e.g. hooked to it knotted or attached to it in a different way. Through the use of a traction device, the device with a very flexible and thin Material are formed in the Einsteckbereich whose material thickness, if necessary can also be significantly below the above values.

Of the Insertion section may optionally preformed without it Bends or prepared hinge-like locations may be formed. Advantageously, however, it is provided with such. Especially Is it possible, that at one end of the insertion portion of the device by existing Angled or prepared hinge-like places at least four bends are formed or formed, which can be formed in their shape during change a plugging operation to let.

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

These Bends between adjacent surface areas of the insertion portion can through be realized a form effect with lasting effect on the material, for example by bending. In this case, the device is preformed. However, it is also possible that the insertion portion in the region of the angled and flat is designed to be movable, and only when inserted into the rebate area takes the appropriate form, that is angled. Also conceivable is a combination of prefabricated bends and hinged trained sections, for example, to achieve even greater flexibility.

The Invention is not on a device with four bends limited. It can Rather, more or fewer bends to be formed, wherein their total number preferably the number of folds of one to open Multiple folding door corresponds. Of course, this device can also be used to open Single fold doors be used.

to better handling of the device or the traction means can in Furthermore, a handle means may be provided. This is a good Dosierbarkeit the Pulling action for opening the door possible. As materials for the traction means are for example wires, cords, belts and the like more.

The Use of an additional Traction means is a matter of course not on a doubly angled or bendable embodiment limited, but rather is on all possible Forms of such devices transferable, especially one with four bends.

The Magnification of the Space between door leaf and frame is preferably at their lower ends in the bottom area carried out. These Location is easily accessible, and over the leverage effect through the distance up to the snapped-in latch This is the easiest way to intervene without damaging the door.

by virtue of the elastic properties of the device or for the production the material used in the device, the bends at least be deformed in part so that a simplification when inserting the device in the enlarged space is effected.

In a preferred embodiment the insertion portion at least partially an elastic Material with restoring forces on, the one for insertion Counteract the deformation of the bends necessary for the device and at least partially return them to their folded form. This results in the advantage that the bends having Import section if possible the same shape as the free space between the door leaf and Frame. This results in a possible low resistance effect during the displacement of the device in the space in the direction of the snapped latch. This is especially important because with increasing number from folding to door and frame the to be overcome Resistance when moving the device increases dramatically. These disadvantages can minimized by the restoring forces in the elastic material and ideally even eliminated.

In a particular embodiment can the bends even temporarily flattened be, leaving a narrow space between the door leaf and Frame is already sufficient to the inventive device in matching To introduce way. The restoring forces are so big that she this temporary At least partially cancel deformation.

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

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

Especially It is advantageous if the geometry of the at least four bends the fold geometry of a Mehrfachfalz door is adjusted. For a variety Of applications, this is relatively easy because there are standard dimensions for folding doors. For folding doors, the of these standard dimensions can deviate the geometries of the bends are changed accordingly, so that the device turn as well as possible in the given Intermediate space is fitted. Ideally, the bends are aligned parallel to each other according to the edges in the folds.

Tools or devices that have generous curves in the bends, naturally require a greater margin in the space between the door leaf and frame and therefore tend with increasing rounding of the edges for clamping. Time and again it was also found that such devices or tools even in the material of the door or the door frame, usually in wood, as a knife einschiebt and this massively damaged. These disadvantages are reduced by an angular formation of the bends.

When Help with pushing back the snapped in Latch has a portion of the plug-in portion inserted in the Condition can reach the latch, at least one slope, its edge when pushing the device on the lower edge the bevelled back the snapped lock latch slips and this by backwards in the direction of the castle urges and so the closing function picks.

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

There It happens occasionally that when trying to open the door, the Device when hoisting over the position of the snapped latch latch slips backwards is another, for the first slope preferably formed mirrored second bevel formed on the device, allowing the tool from a position above the snapped-in Lock latch can also be moved down, as well the just described function for opening the door is effected.

In a particularly preferred embodiment is additional to the first and / or second slope just described a further slope arranged, which preferably connects to the first or second slope and a shallower angle with respect to the longitudinal axis the device comprises. Through this further slope is the Device universally applicable. On the one hand, this can be the release effect When opening the latched latch can be supported, on the other hand can with it also differently positioned lock traps easier reached and open with it become.

to easier handling of the device, this has a handle, which is preferably arranged parallel to the course of the angled portions is. So this can be taken and kept well, which in particular in a flat, thin Material causes significant advantages in handling. This orientation the handle is contrary to the handling of the tool, so that on the one hand with more feeling and on the other hand with larger, targeted usable effort and thus better power transmission can be worked on the snapped lock latch.

drawings

One 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 Mehrfachfalz doors;

2 a schematic representation of the handling of the device according to 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 latched 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 means in plan view and side view.

The 1 shows the device according to the invention 1 for opening multi-fold doors. It has a plug-in section 2 on, in which four bends 3 to 6 are formed. At this insertion section 2 closes another section 7 on, at whose the insertion section 2 a handle at the opposite end 8th is trained.

At the end of the device where the four bends 3 to 6 are formed, two bevels are frontally 9 . 10 educated. They are pushed to open a snapped latch against its lower or upper sloping edge until the latch is pushed back and the door pops up.

For more universal design of the device are in addition to the two slopes 9 . 10 two more bevels 11 . 12 formed on the region facing the latch, the two outer edges in the direction of the second bend 4 limit. As a result, the effect of the device when opening the latch is even further improved. By this shaping, the device can be rotated to a certain extent in the space between the door leaf and frame around a pivot point lying in its surface around, so that the opening of the latch latch is thereby supported.

As a reference line for in plan view approximately rectangular shaped device is a longitudinal axis 13 located. The end face is formed approximately at right angles to this longitudinal axis and has the bevels described above 9 to 12 on. Accordingly, the trained angles in these areas with respect 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 their foot area. The arrow 17 shows the insertion direction of the device 1 in the door gap 16 ,

The 3 again shows the device 1 , located 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 latched latch can be opened according to the invention. The arrow 18 therefore has two directions of arrows, since it occasionally happens that the device 1 slipped over the locking mechanism of the snapped latch and the door still remains closed. Then it is necessary to the device 1 again in the opposite direction, that is to retract or push down, which also unlock the snapped lock latch is possible.

The 4 shows a sectional view through a door 14 , a frame 15 and the device according to the invention 1 in the amount of 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. Facing away from the door gap is the section 7 with the handle attached 8th shown. In the front region of the device, ie at the end at which the bend 3 is formed, which is in the strike plate 20 the frame 15 latched 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 latch 19 to each other. By moving the device 1 against the latch 19 Two oblique edges run along each other, causing the latch in the direction of the arrow 22 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 in addition, which oppose a further complication when opening an accidentally snapped lock latch 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 which is arranged approximately in the middle in the longitudinal direction along the device.

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

Correspondingly, this effect is in the 6 recognizable. In it, the traction means in loose arrangement through the guides 28 along the in 5 shown line to the handle out, and further through this means of the guide arranged therein 27 , The end of the traction device located at this point 25 is so with the handle means 26 connected by pulling on the handle 26 the desired pulling effect can be transmitted to the device. The guides 27 and 28 Although helpful, they are not required to provide the supportive effect of opening the door.

The action on the latch 19 Can handle both over the front section of the insertion area 2 done, which is before the bend 3 located, as well as possibly directly by 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 Although the invention is shown here by way of example with reference to a double-frame door, However, she is not up to the solution limited to such a problem. It can also be a larger number folding in a door be arranged, which are opened by the device according to the invention can. Accordingly, the device according to the invention correspondingly more bends on.
