ADJUSTABLE JAMB STRUCTURE FOR DOORS

Description

Technical Field

[0001] The present invention relates to a jamb structure for doors whose characteristics correspond to the preamble of claim 1.

[0002] A door associated with said structure is also part of this invention.

Domain

[0003] The domain of use is substantially oriented towards the load-bearing structures for doors that are usually identified as jambs and that at present are made up of a intermediate casing and an outer casing that support the jamb.

Definitions

[0004] Jamb: Each lateral stanchion that defines the doorway that are surmounted by the lintel.

[0005] Intermediate casing: Load-bearing frame of the door that supports the door itself and frames it with a possible rabbet.

[0006] Outer casing: frame structure intended to be fixed to the interior wall or exterior wall and to which the intermediate casing is fixed.

[0007] Therefore the definition jamb structure is understood as the outer casing assembly forming the framework of the jamb and lintel.

[0008] In the present invention jamb is understood not only in the strictest sense, but also as the respective lintel.

Background Art

[0009] At present it is known that to fix a door to a wall, the following components are used:

• an outer casing intended to be fixed to the wall by the builder (this outer casing is substantially made form wood and serves to fix the subsequent casing or jamb or frame or panel of the door);
• a intermediate casing, namely a containing frame of the door having supports for the hinging of the door and a profiling of a rabbet of the door itself that completes the jamb, said rabbet being internally provided on the panel both on the stanchions as well in the upper-cross piece or lintel;
• the door that must be mounted by means of hinges on said intermediate casing.

[0010] US-A-3553891 discloses an adjustable doorjamb having a pair of elongated relatively shiftable members, and FR-A1-2307218 discloses a connection assembly for connecting a rabbet profile to a casing. Problems and Drawback of the Background Art

[0011] The problems and drawbacks of the background art refer substantially to the fact that this solution requires precision positioning, namely the adjustment of the vertical and horizontal position as well as coplanar positioning, without which the door does not close well against the jamb.

[0012] Moreover, with the well known systems it is never possible to achieve an exact position with respect to the perpendicularity/verticality/horizontality/flatness of the jambs of the door, namely the lateral stanchions and the upper cross-piece of the casing that is intended to contain the door.

[0013] As a consequence, due to a lack of adjustability, the door will not close correctly. This is more often the case when one wishes to obtain the correct sealing of the door using rabbet gaskets on the jambs e.g. for glass doors or the like.

[0014] In fact it is know that it is very difficult to adjust the casing prior to the assembly of the door and in the known solutions for this type of operation it is necessary to take the door apart before proceeding.

Scope of the Invention

[0015] The scope of the invention is to resolve the aforementioned problems and drawbacks without incurring further costs and without reducing reliability:

• to allow the precise and easy adjustment of the casing with respect to the door;
• to improve functionality and execution;
• to increase performance and to allow this type of adjustment to be made even after the door has been mounted due to the previous poor adjustment of said door and also after different usage time of the door, as it is known that over time doors and jambs can suffer deformations and/or movements.

Solution of the Problem and Identification of the Features of the Invention

[0016] The problem is solved with the characteristics of claim 1.

[0017] The dependent claims represent advantageous preferred solutions that provide improved performance.

Advantages

[0018] In this way the following advantages are achieved:

• to improve functionality and execution;
• increase performance;
• improve jamb adjustment;
• possibility of adjusting and/or setting the jambs also after the door has been mounted, with absolute precision, namely micrometrically by means of the use of the screws between the intermediate casing/jamb and outer casing that operate independently, one for traction (bringing the jamb closer to the outer casing, namely moving it away from the edge of the door) and one for compression (moving the jamb away from the outer casing, namely bringing it closer to the edge of the door), by acting on said opposing screws locking is carried out.

Detailed Description of the Invention in Relation to the Figures

[0020] According to the Figures it is observed that the jamb structure (i) is of the type comprising:

• a U-shaped outer casing (1) with the "U" shape directed towards the internal side of the room namely towards the intermediate casing and the door,
• a T-shaped intermediate casing (2) with the stem of the "T" directed towards the exterior, namely towards the outer casing (1) in order to be engaged to penetrate said outer casing (1) and comprising from above the head of the "T" a female joint central recess for the rabbet (3) to complete the jamb;
• a rabbet (3) intended to be engaged with a male joint by means of two flexible tongues, within said central recess of said intermediate casing (2), said rabbet (3) including on the rabbet-door side, joining means of the respective rabbet gasket (31).

[0021] From the Figures it also is observed that the upper horizontal section (1B) of the outer casing (1) is narrower than the vertical side of the outer casing (1), both comprising a partition wall (11) that creates a double bottom, in such a way that:

• the bottom wall of said U-shaped outer casing (1) has a perforation for the passage of the fastening screw (V1) to the wall (P);
• the partition wall (11) is formed in such a way that:
  a) this axis of the fastening screw (V1) is perforated for respective screwing and

  b) it has further threaded perforations to allow the screwing of traction adjustment screws (V2) and

  c) in another seat, corresponding with rip-like protrusions, it constitutes support for thrust adjustment screws (V3), said seat advantageously containing the tip of the thrust adjusting screws (V3).

[0022] In this way it is possible to position the intermediate casing (2) perfectly in a vertical position with respect to the outer casing (1), the separation between the two being comfortably covered by a cover frame of the known art.

[0023] Therefore, the adjustment can be carried out more precisely, also after the door has been mounted, simply by opening door and acting on said adjusting screws.

[0024] Obviously said gaskets (20,21) being elastically yielding, one of said gaskets being tubular (20).

[0025] Advantageously one of said two gaskets (20,21) consists of an elastically yielding shape that is substantially round (20) and applied on the upper cross-piece of the intermediate casing (2).
