Description

Stopper-integrated synthetic resin door frame symmetrical left and right {PLASTIC DOOR FRAME WITH INTEGRAL STOPPER AND SYMMETRICAL SHAPE}

[Technical field to which the design belongs]

The present invention relates to a synthetic resin door frame, and more specifically, to prevent bending due to shrinkage and expansion of the material, in addition to the symmetrical shape, and to eliminate the inconvenience caused by the additional construction of the stopper, a synthetic resin door frame It is about.

[Prior art]

Recently, door frames made of synthetic resin foam have been manufactured to replace wood. However, the initial synthetic resin door frame had an asymmetrical structure on one side facing the interior and the other side facing the outdoors, and had a disadvantage that the door could only be installed on one side of the door frame when the hinged door was constructed using a hinge.

Moreover, the resin door frame shrinks or expands when the temperature changes due to material properties. As described above, the resin door frame made of left and right asymmetry shrinks and expands in the left and right parts due to its shape characteristics, resulting in a defect in bending the door frame. This will occur.

Therefore, a symmetrical synthetic resin door frame was developed to prevent the door frame from bending and to install doors on both sides of the door frame. As a conventional technique related to such a synthetic resin door frame, there is a prefabricated door frame disclosed in the registered Utility Model 20-287595 and the registered Utility Model 20-281174.

However, since the above-mentioned symmetrical synthetic resin door frame is manufactured separately from the door frame for determining the closing position of the door, it is inconvenient to additionally construct the stopper after constructing the door frame and the door. It has the disadvantage of increasing construction costs.

Therefore, the present invention is to solve the above problems, an object of the present invention to prevent the bending of the door frame due to the expansion and contraction of the material, and to provide a synthetic resin door frame that can solve the inconvenience caused by the additional construction of the stopper It is.

2 to 13 are partial cutaway perspective views of the door frame for explaining the modifications to the embodiment of the present invention.

The present invention to achieve the above object,

Synthetic resin door frame that is connected to the door using a hinge as a frame installed on the wall to form a sliding door, the main body having an arbitrary distance from the wall or floor through the outer support formed on both ends, and larger than the body at the center of the body It includes a stopper having a height and integrally provided with the main body, and provides a synthetic resin door frame characterized in that the cross-sectional shape of the main body and the stopper is symmetrical.

Preferably, a central support may be formed inside the stopper, and a reinforcement may be installed inside the stopper. In addition, a protrusion is formed inside the main body, and a reinforcing material which is positioned by the protrusion may be installed inside the main body.

Preferably, internal supports are formed at both ends of the stopper, and a central support may be formed inside the stopper between the internal supports. The central support may be provided in pairs, the first reinforcement may be installed inside the stopper, and the second reinforcement may be installed inside the main body.

Preferably, a protrusion is formed at the end of the inner support, a first reinforcing material positioned by the protrusion is installed inside the stopper, and a second reinforcing material may be installed inside the body.

Preferably, the height of the center support is made smaller than the height of the inner support, and a reinforcing member engaged with the center support may be installed inside the stopper. In addition, a first protrusion is formed at the end of the inner support, a second protrusion is formed at the end of the central support, and a pair of reinforcing members positioned by the first and second protrusions may be installed inside the stopper.

Preferably, the stopper may be formed in a square pipe shape having an inner hollow, in which case a reinforcement may be installed in the inner hollow of the stopper.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a perspective view of a synthetic resin door frame according to an embodiment of the present invention.

As shown, the synthetic resin door frame 10 is installed on the wall (1) as an elongate frame that a person can enter, the door (2) of the door frame (10) facing the interior through the hinge (3) It is installed on one side or the other side of the door frame 10 facing the outdoor to constitute a swing door (4).

The door 2 may be installed at both the inside and the outside of the door frame 10 due to the symmetrical structure of the door frame 10. In this embodiment, the stopper 11 defining the closing position of the door 2 is provided. Installed in the door frame 10 to eliminate the inconvenience caused by the additional construction of the stopper (11).

That is, the synthetic resin door frame 10 according to the present embodiment has a main body 13 having an arbitrary distance from the wall or the floor through the outer support 12 formed at both ends, and the main body 13 at the central portion of the main body 13. It consists of a stopper 11 having a greater height and integrally provided with the main body 13, and has a cross-sectional shape of symmetry.

As seen from the cross section of the door frame 10, both the stopper 11 and the main body 13 are orthogonal to the outer support 12, and have a flat shape so as not to cause inconvenience when a person enters or exits. As a result, when the door 2 is closed, the door 2 is caught by the stopper 11 by the height difference between the stopper 11 and the main body 13 to determine the closing position.

The synthetic resin door frame 10 is typically made of foamed PVC, has the advantages of excellent water resistance and corrosion resistance.

By the structure of the door frame 10 described above, in the present embodiment, not only the door 2 can be installed on the inside or the outside of the door frame 10, but also the bending of the door frame 10 during shrinkage expansion due to temperature changes can be achieved. It is expected to be convenient in construction because it does not need to additionally install the stopper 11.

Next, modifications to the embodiment of the present invention will be described with reference to FIGS. 2 to 13.
