Description

[Detailed Description of the Invention] The present invention is a simple and effective fixing device for tightly fitting and fixing a door frame, on which a screen door, a door body, etc. is mounted inside, into an entrance frame of a back door or the like.

Conventionally, in most cases when a door frame is fitted and fixed to an entrance frame, a wedge piece is inserted between the door frame and the entrance frame and the door frame is fastened with nails or screws, or a fastening method consisting of a female thread and a bolt is used. The bolts are inserted with gold and held in tension by threading them in and out.

However, in the former case, not only is it time-consuming to insert the wedge piece, but also there is a drawback that it is easy to cause misalignment between the entrance frame and the door frame when screwing the nails, and in the latter case, it is due to the insertion and removal of the bolt, so it is difficult to insert the wedge piece. The disadvantage is that the operation is troublesome, and in the case of a recessed stile, the equipment and operation are difficult.

This invention proposes the following device which does not have the disadvantages of the conventional method and can be fixed always correctly and easily.

That is, as shown in the drawings of the embodiment, a door frame 1 made of light metal is fitted into an entrance frame 4 that is more prominent than a pillar, etc., and a door body is mounted inside. At the locations, there are adjustment pieces 2 made of synthetic resin that are trapezoidal in shape and have screw holes R extending from the front to the back.
The upper ends of each elevator 3, which is shaped like a letter 3 and has vertically bored holes in the front wall 3', are interlocked with each other and placed thereon. The screw rods P inserted through the holes e drilled on the left and right sides of the front of the rising wall of the stile 1' are screwed together, and 5 in the drawing is the rear wall of the upper stile 1' of the door frame 1. A gap closing piece attached to the gap between the upper end and the entrance frame 4 is shown.

Since the present invention is constructed as described above, when fixing the door frame 1 to the metal entrance frame 4, the screw rods P on the front left and right sides of the upper stile 1' of the door frame can be rotated in the forward direction with a screwdriver. The adjustment piece 2 in the groove H that is screwed into the threaded rod is gradually drawn toward the front, and the elevator 3 whose tip rests on the upper slope of the adjustment piece gradually rises until finally shown in FIG. The door frame 1 is pressed against the lower surface of the upper frame of the entrance frame 4 like a medium-chain green stone, and the door frame 1 is therefore fixed to the entrance frame 4.

In this case, when fixing the door frame as described above, the operation is extremely simple because the head of the screw rod exposed on the front side of the upper stile of the door frame is simply rotated. Since no impact or vibration is applied to the door frame, there is no fear of misalignment between the door frame and the entrance frame, and this type of door frame always has the effect of correctly and firmly fixing the door frame to the entrance frame. This is an extremely advantageous device as a fixing device.

[Brief explanation of the drawing]

Figure 1 is a front view of the door frame with the door body fixed to the entrance frame, and Figure 2 is an enlarged vertical cross-section of the main part of the same device installed between the upper stile of the door frame and the lower surface of the upper frame of the entrance frame. 3 are enlarged perspective views of the proposed device. 1 is the door frame, 1' is the upper stile, 2 is the adjustment piece, 3 is the elevator, 3'
is the front wall, 4 is the entrance frame, D is the door body, H is the groove, h is the vertical hole, P is the screw rod, and R is the screw hole.

Claims (1)

[Scope of utility model registration request] In the door frame 1 which is fitted into the entrance frame 4 and has a screen, door, etc. mounted inside, screw holes R are bored on both sides within the concave groove H of the upper stile 1' in a trapezoidal shape and from the front to the back. Each adjustment piece 2 and each lift 3 having an inverted L-shape on the side and having a vertically elongated hole bored in the front wall 3' are placed on the front side of each adjusting piece 2 so as to interlock with each other, and the vertical length of these lifts is Screw the screw rods P inserted through the holes e drilled on the left and right sides of the front of the rising wall of the upper stile 1' in the door frame 1 into the screw holes R of the holes and adjustment pieces. A device for fixing a door frame for mounting a door body to an entrance frame of a back door etc. which is pressed against the lower surface of the upper frame of the frame 4.
