Description

A METHOD FOR FITTING A DOOR FRAME IN A WALL RECESS FIELD

The present disclosure relates to the field of door frames. BACKGROUND

Conventionally, a door frame is fitted in a wall recess using an adhesive and/or fasteners such as nails. The sole use of adhesive does not provide a secure fitment of the door frame within the wall recess, and the door frames are susceptible to deformation and/or warping. The nails are clearly noticeable which adversely affects the aesthetic look of the door frame. Further, an additional layer of decorative sheets is required to be applied on the door frame to conceal the nails, thereby increasing the overall cost of the door frame. Furthermore, the nails are difficult to remove, and can damage the door frame while separating the door frame from the wall recess. This compromises the strength of the door and door frame.

Therefore, there is felt a need of a method for fitting a door frame in a wall recess that alleviates abovementioned drawbacks of the conventional methods.

OBJECTS Some of the objects of the present disclosure, which at least one embodiment herein satisfies, are as follows:

An object of the present disclosure is to provide a method that securely fits a door frame within a wall recess of any wall structure.

Another object of the present disclosure is to provide a method that eliminates the need of nails to fit a door frame.

Yet another object of the present disclosure is to provide a method that facilitates removal of a door frame from a wall recess without damaging the door frame.

Yet another object of the present disclosure is to provide a strengthened door and a strengthened door frame. Other objects and advantages of the present disclosure will be more apparent from the following description, which is not intended to limit the scope of the present disclosure.

SUMMARY

The present disclosure envisages a method for fitting a door frame within a wall recess. In accordance with the method of the present disclosure, initially, at least three frame sections are assembled to form the door frame. A first fixture is fitted on an operative side surface of at least one of the frame sections. Further, a second fixture is fitted on a surface of the wall recesses interfacing the operative side surface of the frame section. The first fixture and the second fixture have complementary profiles to facilitate interlocking. The door frame is then inserted within the wall recess to facilitate engagement of the first fixture and the second fixture, thereby securing the door frame within the wall recess.

The method further comprises a step of fitting a third fixture proximal at least one longitudinal end of the at least one frame section. The third fixture is engageable with a complementary hole formed in the wall recess and/or floor to limit the displacement of the door frame within the wall recess.

More specifically, three wooden frame sections (102) are connected to each other to form the door frame (100). The wooden frame sections (102) can be connected to each other using wooden dowel and barrel nut assembly (104).

In an embodiment, a groove is configured on the door frame (100) to accommodate a rubber gasket. The door frame (100) has gasket which facilitates soundproofing of the room, improves air-conditioning efficiency, prevents dust, and ingress. The gasket also reduces the door hard closing noise as well as minimizes the shocks and vibrations felt to the door frame (100) and the supporting wall. In an exemplary embodiment, the groove is configured on each of the front and back sides of the door frame (100).

In an embodiment, the method further includes the step of applying a layer of epoxy resin at an operative bottom surface of the door frame (100). In another embodiment, the method further includes a step of applying a transparent silicon sealant over the layer of epoxy resin. The epoxy resin and silicon sealant layer make the door frame (100) water and moisture resistant.

The first fixture (150) is fitted on an operative side surface of at least one of the frame sections (102). In an embodiment, the first fixture (150) is fitted on an operative side surface of those two frame sections (102) which form columns of the door frame (100). In an embodiment, the first fixture (150) comprises a connector (152) and a flange (154). The connector (152) is fitted on the operative side surface of the frame sections (102). The connector (152) has a head portion and a stem portion (156). The stem (156) has external threads configured thereon. The head portion has a first plate (158) and a second plate (160). The first plate (158) and the second plate (160) are arranged in a spaced apart configuration such that a channel (162) is formed between the first plate (158) and the second plate (160). The flange (154) is attached to the operative side surface of the frame sections (102). Further, the flange (154) has a plurality of holes configured thereon to facilitate attachment of the flange (154) to the frame sections (102). The flange (154) has a threaded hole configured to receive the connector (152).

The second fixture (180) is fitted on a surface (182) of the wall recess interfacing the operative side surface of the frame section (102) on which the first fixture (150) is attached. More specifically, the second fixture (180) is attached to that side of the wall recess which is to be attached to the sides of the door frame (100) in order to interface the connector (152) to the second fixture (180). The first fixture (150) and the second fixture (180) have complementary profiles to facilitate interlocking therebetween.

The second fixture (180) is a bracket defined by a body (184). A slot (186) is configured on the body (184) to receive the connector (152). More specifically, the slot (186) is configured to receive the channel (162) therein. The channel (162) and the slot (186) have complementary profiles such that the connector (152) securely fits in the bracket. The second fixture (180) has a plurality of holes (188) configured on the body (184) to facilitate attachment of the second fixture (180) with the surface (182) of the wall recess.

The method further comprises the step of rotating the connector (152) to tighten the engagement of the first fixture (150) and the second fixture (180) and to adjust the gap between the frame section (102) and surface (182) of the wall recess. In an embodiment, the second plate (160) of the first fixture (150) is rotated using a spanner (250) to tighten the engagement. The spanner (250) is defined by a body (252) and a head (254). The head (254) receives the second plate (160) in order to facilitate rotation of the second plate (160).

In an embodiment, the method further comprises the step of fitting a third fixture (200) proximal at least one longitudinal end of the at least one frame section (102), the third fixture (200) being engageable with a complementary hole (52) formed in the wall recess and/or floor (50) to limit the displacement of the door frame (100) within the wall recess.

In an embodiment, the third fixture (200) comprises a body (202) and a connecting member (204). The body (202) has two elongated slots (206) configured thereon. The elongated slots (206) receive fasteners (210). The body (202) is configured to be fitted on the frame sections (102). The body (202) is fitted using the fastener (210). The body (202) is configured to slide along the elongated slots (206) when a predetermined force is applied on the body (202). The connecting member (204) extends from the body (202), and is configured to be received in a hole configured on the floor (50). The method further includes a step of applying a predetermined force on the third fixture (200) to engage the third fixture (200) with the complimentary hole. In an embodiment, the predetermined force is applied using a hammer or a spanner (250). After applying the predetermined force, the third fixture (200) slides downward along the slots (206), thereby engaging the connecting member (204) with the complimentary hole (52). Once the first fixture (150), the second fixture (180), and the third fixture (200) are connected at their respective positions on the door frame (100) and the wall recess, the door frame (100) is inserted within the wall recess such that the first fixture (150) is engaged with the second fixture (180), and the third fixture (200) is engaged with the complementary hole (52) on the floor (50).
