Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a door frame installed in an opening of a wall surface of a building to which a door or the like is attached.

[0002]

[Prior Art]

 As shown in FIG. 3, a door frame 110 of a conventional example is a door in which a main body 101 having a groove portion 101a extending in the longitudinal direction and a ridge 102a extending in the longitudinal direction and capable of being fitted into the groove portion 101a are provided in a protruding manner. Consists of 102. When installing the door frame 110 in the opening 105, the main body 101 is fixed to the frame member 104a of the wall panel 104 by the screw 106 penetrating from the bottom of the groove 101a. Then, the door stop 102 is fixed to the main body 101 by fitting the ridge portion 101b into the groove portion 101a.

[0003]

[Problems to be solved by the device]

 If the door frame 110 of the conventional example is left in a state of being attached to the opening 105 at a construction site, damage may occur due to contact with a worker passing in the vicinity or a material in the middle of transportation. Therefore, in order to protect the door frame 110, a protective sheet 103 made of foamed plastic or the like is coated around the door frame 110. However, a step of fixing the main body 101 with a screw 106 and a step of fixing the door stop 102 to the main body 101 Therefore, the protective sheet 103 had to be separately covered after these steps were completed. As described above, the construction work is complicated because there is a lot of labor on site.

An object of the present invention is to provide a door frame that has a protective function and is easy to install.

[0005]

[Means for Solving the Problems]

 The door frame of this invention has a peelable protective film adhered to its surface.

[0006]

[Action]

 Since the door frame of this invention has a peelable protective film on its surface, there is no need to apply a protective sheet as in the conventional example, and the construction at the construction site becomes easy.

[0007]

【Example】

 A door frame according to an embodiment of the present invention will be described with reference to FIGS. 1 and 2. As shown in FIG. 1, a door frame 10 includes a main body 1 and a door stop 2, and a peelable protective film 3 is attached to each of the front surfaces 1b and 2b. The protective film 3 is a combination of the films 1f and 2f, and is a plastic film made of vinyl chloride or the like having an adhesive force that can be easily peeled off artificially. The door stop 2 is provided with a projecting ridge portion 2a extending in the longitudinal direction on a back surface 2c of a long square bar. The surface 2b and both side surfaces of the door stop 2 are covered with the film 2f, and the total width dimension is T. The main body 1 is a long flat plate having a groove 1a formed in the center of the surface 1b and extending in the longitudinal direction so that the protrusion 2a can be fitted therein. Each of the corners located on both sides of the groove 1a is located in the main body 1. It is chamfered. As shown in FIG. 2A, the film 1f covers the surface 1b of the main body 1 excluding the zone of the width dimension T straddling the groove portion 1a, the vicinity of both side edges of the back surface 1c, and both side edges.

The installation of the door frame 10 in the opening 5 will be described. As shown in FIGS. 1 and 2 (b), by screwing a screw 6 penetrating the bottom of the groove 1a into the frame member 4 and embedding an end of the face member 4c in the back surface 1c, the main body 1 is wall-mounted. Fix to panel 4. Next, the ridge 2b is fitted into the groove 1a to fix the door stop 2 to the main body 1. A door 7 is installed in the opening 5.

As described above, since the surfaces 1b and 2b of the door frame 10 are covered with the films 1f and 2f, when the door frame 10 is installed in the opening 5 at the construction site, the door frame 10 passes through the vicinity. It is possible to prevent damage due to contact with workers or materials during transportation. Further, since the films 1f and 2f have an adhesive force that can be easily peeled off artificially, they can be peeled off easily by pulling them by hand when they are no longer needed.

[0010]

[Effect of the device]

 Since the door frame of this invention has a peelable protective film on its surface, even if the door frame is left in the state of being installed in an opening in a construction site, it may be contacted by a worker passing through it or a material being transported. Can prevent damage. Moreover, when the covering is no longer necessary, the protective film can be easily peeled off by pulling it by hand.
