Description

Field of the Invention

The present invention relates to a tensioning mechanism, in particular an adjusting device for a tensioning mechanism, which is suitable for being fastened to a door which comprises two walls arranged at a certain distance from one another.

State of the art

Clamping mechanisms are known which can be arranged on a double-walled door, which is used, for example, in air conditioning, ventilation, cooling, soundproofing (soundproofing cabins) and painting applications and comprises two walls arranged at a certain distance from one another, so that an interior space between them the walls is formed.

Such tensioning mechanisms may include a shaft that extends through the door in the interior between the two walls of the door, and a latch or latch that is connected to the shaft so that it rotates with it and / or relocated.

The shaft may include two opposite ends located on the respective sides of the door and associated with a first handle and a second handle, respectively.

Alternatively, the shaft can comprise two ends which are arranged on the respective sides of the door and of which only one is assigned to a handle.

In order to fix each of the handles stably to the ends of the shaft and to the door, they are fixed to the shaft by known means and pressed against the two walls of the door, where they are then further fixed by known means.

Since the space between the two walls of the door can be empty or filled with any insulating material, for example porous, the walls of the door can be deformed by the opposing forces which act when the tensioning mechanism is fixed to the door and the handles are pressed against one another .

A known solution to the aforementioned problem is to arrange a spacer tube between the two walls of the door so that it is fixed on the inside of both walls of the door. The shaft that extends through the door extends through the spacer tube.

When the handles are fixed to the ends of the shaft and to the walls of the door, the spacer tube prevents the walls of the door from being pressed against one another and the door from being deformed. However, the length of the spacer tube must correspond exactly to the distance between the walls of the door to prevent them from being pressed against each other.

If the spacer tube is slightly longer or shorter, the door will be deformed.

In addition, since the cross-section of the spacer tube must be larger than the opening in the walls of the door through which the shaft extends, the spacer tube must be placed between the two walls before the door is installed. If a pre-assembled door is to include a handle, it is not possible to place the spacer tube between the walls of the door.

As a result, the bolt or the latch can be in the wrong position in relation to the door frame or in any case the striking plate into which the bolt or the latch is to snap when the lock is closed.

A method for solving the above problems is from the document EP 2553188 A is known which proposes an adjusting device which comprises a roller bolt or a roller trap which is adjustable by means of a screw and a nut in connection with a holder which is provided with a groove with a scale. The roller latch is adapted to remain in contact with an inside of a door frame when the tensioning mechanism is in a locked position. The screw extends through the roller trap and the holder and is in engagement with the nut. The roller trap is rotatable with respect to the screw extending through it, while the nut is coupled to the holder such that the roller trap is slidably suspended from the holder. This displaceable suspension means that the roller can be adjusted along a direction running essentially parallel to the longitudinal direction of the tensioning mechanism.

The role can thus be adjusted to adapt to a certain distance between the walls of a door. To adjust the position of the roller, the screw is loosened so that the nut in the holder can be moved along the groove to a new position. The scale on the holder gives an indication of the position of the roller along the longitudinal axis of this holder.

It should be noted that the term “roller trap” is used in the following to refer to a bolt which is provided with a - normally rotatable - roller which is elastic or not actuated can be and is suitable, in a striking plate or in an area of a frame or a post or frame of a door and to snap to enable the closing or opening of a lock.

However, such an adjustment device has several disadvantages, for example the low precision in adjusting the position of the roller and the complexity of the assembly of the adjustment device, which consists of numerous components, and the adjustment process itself, which has to be carried out in numerous steps.

Another disadvantage of the existing tensioning mechanisms is that they only allow adjustment of the longitudinal arrangement of the tensioning mechanism when the door on which they are mounted is open, i.e. when the door is mounted. H. if the latch is not locked into a striking plate or an area of a frame or a post or frame of a door.

As a result, a tensioning mechanism for a double-walled door is required which prevents the walls of the wall from being pressed against one another too strongly or insufficiently. A tensioning mechanism is also required, which can be adjusted precisely and easily depending on the distance between the walls of the door. Furthermore, such a tensioning mechanism must be able to be arranged on a preassembled door. In addition, there is a need for a tensioning mechanism which can be adjusted when the door on which it is mounted is closed, i. H. when the latch is engaged in a striking plate or an area of a frame or a post or frame of a door.

A “double-walled door” is understood to mean a door or a door leaf or the like which has two essentially parallel walls, which are preferably arranged at a certain distance from one another and the respective outer and inner surfaces of the room, the cabin , Define the room or the like, which are closed with the door, so that an interior of the door is formed between the two walls, which may or may not be filled with other walls and / or with a foamable and / or insulating material. According to a first aspect of the invention, these objects are achieved with a tensioning mechanism according to the invention which is suitable for being received on a double-walled door which comprises a first wall and a second wall and a space between the two walls, the tensioning mechanism comprising:

• - A shaft rotatable about its own axis with a first and a second end, which is adapted to extend through the space between the two walls of the door;
• - An actuator with an attachment portion and a manually rotatable portion, the attachment portion being adapted to be attached to the first end of the shaft so that it is non-rotatably connected to it;
• an adjusting device which comprises a holder attached to the rotatable shaft with a main body which is preferably hollow and extends predominantly in a longitudinal direction running parallel to the direction of extension of the shaft,
• - A bolt or a latch, preferably of the type with a roller, which is slidably attached to the holder via a slide, so that he or she moves in a longitudinal direction of the holder, ie along a direction essentially parallel to the direction of extension of the shaft A plurality of positions can be adjustably positioned, and wherein the slide of the latch or bolt has a threaded cavity (thread insert) and the adjusting device comprises a worm which is rotatably coupled to the holder with respect to the holder and is inserted into this threaded cavity, wherein the rotation of this worm determines the set positioning of the carriage with respect to the holder along the longitudinal direction of the holder.

If such a tensioning mechanism is positioned on a double-walled door of the type mentioned above, the tensioning mechanism can advantageously be adjustable, that is to say by changing its arrangement in the longitudinal direction, fixed to the door in order to adapt to the dimensions of the door and the corresponding striking plate (for example a post or frame or frame of the opening to which the door belongs) without the risk of the door, the frame of the respective room to which the door is attached and / or the respective seals being deformed or not optimal closing of the room, room or cabin to which the door is attached is obtained.

It should be noted that the mechanism of the invention has no restrictions as to whether the latch or bolt is located near the inside of the room or the outside of the room to which the double-walled door is hinged, and thus any arrangement of the Actuator and the latch or bolt falls within the scope of protection claimed here.

The precise adjustment of the latch or bolt in relation to the actuating shaft, which can be obtained thanks to the mechanism with worm and thread cavity or thread insert, makes it possible to insert the latch or bolt of the tensioning mechanism in relation to the respective door leaf or striking plate to arrange the latch or bolt extremely precisely, so that the locking pressure of the door with the respective door leaf or the striking plate of the frame of the room, the cabin or the room to which the door is attached is fine-tuned.

This locking pressure of the door with the respective door leaf of the room to which the door is attached is particularly important if seals are arranged between the door and the respective frame of the room to which the door is attached, which seal the passage of fluids, especially air or dust or other substances, because if the snap-in pressure is too low, the seals cannot guarantee complete tightness, while if the snap-in pressure is too strong there is a risk that the door and / or the seals and / or the Frames are deformed.

The adjusting device of the tensioning mechanism according to the invention advantageously facilitates the process of adjusting the arrangement of the tensioning mechanism in the longitudinal direction, since only the rotation of the screw is required to carry out this adjustment.

Thanks to such an arrangement, which allows the longitudinal arrangement of the tensioning mechanism to be adjusted simply by turning the screw, it is also possible to operate the tensioning mechanism both when the door is closed, i.e. when the door is closed.

H. that it is possible to adjust the longitudinal arrangement of the tensioning mechanism both when the latch or bolt is engaged in a striking plate or an area of a frame or a post or frame of a door, and also when it is not engaged.

The possibility offered by this invention, thanks to the engagement between the screw and the cavity with a threaded insert of the slide of the latch or bolt, can be used to fine-tune the longitudinal position of the latch or bolt when the door is closed, without any overpressure being exerted on the door and thus also on the The latch or bolt acts, the position of which can change quickly and violently, is extremely important, particularly during the installation phase and especially when maintaining this tensioning mechanism.

This advantageously makes the adjustment and maintenance process of the tensioning mechanism more efficient, in particular in mechanisms which are used, for example, in air conditioning, ventilation, soundproofing and painting applications, in which it is required that between the interior and the exterior of the heat, Substance or sound exchange is controlled and takes place in compliance with controlled value ranges, which is why a tensioning mechanism according to this invention, which can be adjusted without opening the door, is appreciated. H. without establishing a connection between the interior and exterior, for example by placing the adjusting device on the wall of the door facing the exterior.

The adjusting device according to the invention thus advantageously allows the adjustment process of the tensioning mechanism even under stress, i. H. it allows this adjustment to be made by exerting a force on the adjusting device which is transmitted from the tensioning mechanism to the walls of the door in two opposite and mutually parallel directions perpendicular to the extension surfaces of the two walls of the door.

An adjusting device according to the invention advantageously enables a fine and precise adjustment of the position of the slide and of the roller trap or the roller bolt attached to it with respect to the holder.

According to a further aspect of the invention, the adjusting device comprises fastening means in order to fasten the carriage stably but reversibly to the holder. These fastening means preferably comprise a grub screw or other thread means and a bore, the latter being positioned on the slide and being suitable for the passage of the grub screw or other thread means.

According to a further aspect of the invention, the position of the slide in relation to the holder is selected by the user finely and adjustably by turning the screw in the thread which is located in the threaded cavity of the slide.

The position of the slide in relation to the holder and thus in relation to the striking plate, into which the latch or bolt engages when the door is closed, is advantageously selected finely and precisely.
