Description

FIELD OF THE INVENTION

The present invention relates to door jamb constructions, the characteristics of which correspond to the restrictive part of the claims. A door combined with this design is also the subject of the present invention.

Application area

The present invention is applied essentially in load-bearing door structures, which are usually door jambs, and in the embodiment of the present invention are assembled from a door casing and an outer door frame that holds the door jamb.

Terminology used

Jamb: any side pillar that defines a doorway and that is crowned by a door jumper.

Platband: load-bearing door frame that holds the door itself and possibly has a groove.

Outer box: a frame designed to be fixed on the inner wall or on the outer wall to which the platband is attached.

Therefore, door jamb refers to the assembly of the outer frame forming the jamb frame and the door jumper.

In the present invention, a door jamb is understood not only as a jamb in the strict sense, but also as a corresponding door jumper.

State of the art

It is known that currently the following elements are used to fasten a door to a wall:

- an outer door frame, which is attached to the wall with the help of a builder (this outer frame, in essence, forms a wooden base and is used to fasten the door frame, or platband, or frame, or door panel);

- the casing, namely the door bearing frame, having supports for hanging the door and forming a groove for the door itself, which form a jamb, while the specified groove is inside the panel both on the racks and on the upper cross-shaped element or door jumper;

- a door that must be installed on the corresponding hinges in the indicated box.

US-A-3553891 and FR-A1-2307218 describe an adjustable door jamb having a pair of longitudinally displaceable elements.

The disadvantages of the known structures are essentially due to the fact that they require precise positioning, namely, adjusting the vertical and horizontal positions, as well as adjusting the position on the plane, without which the door does not close well in a jamb.

Moreover, the known structures are not able to provide accurate positioning of the door jamb with respect to ensuring its perpendicularity / verticality / horizontalness / flatness, namely with regard to the side pillars and the upper crossbars of the platband constituting the door.

As a result of this, due to the lack of adjustment, the door does not close correctly. Most often this occurs when it is necessary to obtain a good door seal using gaskets in grooves on the jambs, for example, for glass doors or the like.

From practice it is known that it is very difficult to adjust the casing before assembling the door, and in known methods for performing this kind of work, it is necessary to remove the door before fitting it.

Disclosure of invention

The objective of the present invention is to solve the above problems and eliminate the disadvantages without increasing the cost and without reducing the reliability of the structure so that:

- provide accurate and easy adjustment of the platband relative to the door;

- improve the functionality and operation of the door;

- increase productivity and provide the required adjustment even after installing the door due to poor preliminary adjustment of the specified door and also after using the door, because it is known that worked doors and jambs may experience deformations and / or unwanted displacements.

Problem Solving and Description of Features of the Present Invention

The problems are solved in accordance with the characterizing part of the main claim.

Additional claims reflect the advantages of preferred embodiments of the present invention, providing improved operation of the device.

In accordance with the present invention, the following advantages are achieved:

- improved functionality and operation of the door;

- increased productivity;

- improved jamb adjustment;

- it is possible to adjust and / or install the jambs with absolute accuracy also after the door is installed, namely in the micrometric range with the help of screws between the platband / jamb and the outer box, which work independently, one for pulling (putting the jamb closer to the outer box, namely, moving it away from the edge of the door) and one for compression (moving the jamb away from the outer box, namely moving it closer to the edge of the door) by tightening these contra false screws.

Detailed description of an embodiment of the present invention shown in the drawings

As shown in the drawings, a door jamb (i) of this type comprises an outer U-shaped box (1) directed toward the inside of the room, namely, the platband and the door; intermediate platband (2) of a T-shape with a T-shaped shank directed outward, namely towards the outer box (1) so as to connect with it by penetrating into the specified outer box, and consisting of the aforementioned T-shaped head forms with a recess in the center for the groove (3), which allows you to complete the formation of the jamb; a groove (3) intended for connection with a pin joint using two flexible tongues and having a specified central recess in the casing (2), while the groove contains on the side of the groove-door connecting means for corresponding sealing (31) of the groove.

From the drawings it can be seen that the upper horizontal part of the outer box (1 V) is narrower on the vertical side of the outer box (1), while both of them contain an intermediate separation wall that creates a double bottom (11), while the lower wall has an opening for the passage of the fastening screw (V1) to the wall (P); the partition is formed in such a way that: a) the axis of the fastening screw (V1) is perforated to allow screwing in, b) it has threaded holes that allow the adjustment screws (V2) to be screwed in, and c) in another place, it contains a support for the screws (V3) pressure adjustment, while the specified location in the preferred embodiment contains the tip of the pressure adjustment screws.

In this way, the platband (2) can be installed strictly upright relative to the outer box (3), while the gap between them is closed by a suitable frame of known design.

Therefore, the adjustment can be made more accurately, even after installing the door, simply by opening the door and acting on the adjustment screws.

It is obvious that the seals are resiliently flexible, while one of the seals is tubular (20).

An advantage of one of these two seals on the intermediate casing-outer box is the resilient shape, which is essentially round and is used on the upper casing of the casing (21).

Clarification of the term

The bottom wall is the U-shaped bottom of the outer U-shaped box.
