TECHNICAL FIELD The present invention relates to the field of building doorframes.

BACKGROUND ART The term doorframe is defined by Merriam Webster dictionary as "the jambs and upper transverse member enclosing the sides and top of a doorway and usually supporting a door". Dictionary.com website defines this term as "the rectangular frame that surrounds an opening into which a door fits".

Doorframes have usually two objects: to cover the edge of a doorway for providing to the construction an esthetic aspect, and to support the door thereof. Presently doorframes comprise a flexible band at the corner where a door meets the doorframe thereof, for sealing the doorway.

One of the obstacles facing a doorframe (lintel) installation is that there are three common widths of a wall: 10, 12 and 14 cm, and not one. Furthermore, the thickness of a wall varies from wall to wall because the wall is covered with a layer of plaster, and therefore there are differences of millimeters between the design and the result in practice. Presently, doorframes are glued to the wall of the doorway thereof. The glue used for this purpose is foamed Polyurethane. This makes the doorframe a onetime component. In other words, once a doorframe has been glued to the wall, if the installation is not satisfactory, the entire doorframe must be removed, and another doorframe installed.

All the methods described above have not yet provided satisfactory solutions to the problem of installing a doorframe on a doorway.

It is an object of the present invention to provide a solution to the above-mentioned and other problems of the prior art.

Other objects and advantages of the invention will become apparent as the description proceeds.

SUMMARY OF THE INVENTION

The present invention is directed to a doorframe (ll) comprising:

an L profile, having a first panel (13a) and a second panel (13b), wherein an angle between the first panel and the second panel is 90 degrees, wherein the first panel (13a) is longitudinally splitable!

a base profile (14), having a first mortise (18); and an opposite profile (15) to the second panel (13b), the opposite profile (15) being connected or connectable to the base profile (14),

thereby a width of the doorframe (ll) can be shortened for conforming different widths of a wall.

According to one embodiment of the invention, the connectability of the opposite profile (15) to the base profile (14) is obtained by a second mortise (19) of the base profile (14), for connecting therein the opposite profile (15) in a tenon- mortise manner.

The base profile (14) may further comprise a longitudinal depression (21) at a circumference thereof, for filling therein adhering substance, for adhering thereto the L profile (13).

According to one embodiment of the invention, the edges of the L profile (13) and the opposite profile (15) are bent (24), for (a) allowing a thicker appearance of the profile while using a thinner profile, and (b) generating a space that can be filled with adherent, for adhering the profile to a wall or an adjacent profile.

According to one embodiment of the invention, the splitability is obtained by longitudinal split grooves on the L profile. According to another embodiment of the invention, the splitability is obtained by longitudinal perforation lines on the L profile. According to yet another embodiment of the invention, the splitability is obtained by longitudinal breakable lines on the L profile.

According to one embodiment of the invention, at least one panel of the doorframe is attached to the wall (12) by bolts.

The present invention will be understood from the following detailed description of preferred embodiments ("best mode"), which are meant to be descriptive and not limiting. For the sake of brevity, some well-known features, methods, systems, procedures, components, circuits, and so on, are not described in detail.

Fig. 1 is a perspective view of a doorframe, according to one embodiment of the invention.

The doorframe, which is marked herein by reference numeral 11, surrounds the door 10. Reference numeral 12 denotes a wall.

Fig. 2 is a sectioned illustration of a doorframe installed on a doorway, according to one embodiment of the invention.

Fig. 3 is a top view of a set of profiles from which a doorframe is composed, according to one embodiment of the invention.

Fig. 4 is a top view of a set of profiles installed on a wall, according to one embodiment of the invention.

The doorframe is composed of three profiles : an L profile 13, a base profile 14, and an opposite profile 15. The L profile 13 comprises two panels 13a and 13b, which generate a 90 degrees angle between them.

The base profile 14 comprises a first mortise (depression) 18, correspondingly to panel 13a of L profile 13. Thus, the L profile 13 connects to the base profile 14 by panel 13b which functions like a tenon, i.e., a tenon, a tenon-mortise joint.

An essential feature of the L profile is that the width of panel 13a thereof can be shortened. This can be done, for example, by a perforated longitudinal line in the panel, a thinner longitudinal line along which the panel may be longitudinally broken, and the like. Of course, the L profile is manufactured such that it comprises the split line (i.e., perforation line, etc.). As such, the width of doorframe 11 can be shortened in order to correspond to the width of wall 12.

Furthermore, since the tenon has a degree of freedom to move within the mortise, the adjustment of the doorframe to the wall width is simple and leaves no gaps between the lintel and the wall.

According to one embodiment of the invention, the base profile 14 comprises a second mortise (depression) 19, correspondingly to a tenon panel 17 of the opposite profile 15. Thus, the opposite profile 15 connects to the base profile 14 by a tenon a tenon-mortise joint. Alternatively, the opposite profile 15 may be manufactured as connected to the base profile 14.

Reference numeral 20 denotes a seal, such as a rubber band, which seals the space between door 10 and the base profile 14.

Reference numeral 21 denotes a depression, which can be filled with glue for adhering the L profile 13 to the base profile 14. The generated depression 22 is used for the same purpose.

Reference numeral 24 denotes a bend at the edge of L profile 13. The bend may provide two advantages: (a) allowing a thicker appearance of the profile while using a thinner profile, and (b) generating a space that can be filled with adherent, for adhering the profile to a wall or an adjacent profile. The bend 24 is optional, not mandatory.

Each of Figs. 5 and 6 is a perspective-sectioned view of a doorframe, according to one embodiment of the invention.

The difference between the panel 13a of Fig. 5 and the same component of Fig. 5 is that the width of the doorframe 11 of Fig. 5 is 14 cm, while the width of the doorframe 11 of Fig. 6 is 10 cm.

The reason for the difference is the width of panel 13a in the figures: panel 13a of Fig. 5 comprises four longitudinal shafts 23, while the same panel of Fig. 6 comprises only two shafts. A user may cut the profile with a knife along any of the shafts, since the shaft is used as a rigid guiding line (a user may cut the panel by a knife while the side of the blade thereof touches the shaft's wall).

Also is seen in these figures the split line 25, which is drawn as a dashed line. Returning to Fig. 2, there is shown bolts 26. The bolts may be used as a substitute to the adherent. As such, the doorframe may be disassembled any time, and re-assembled.
