Description

[Detailed Description of the Invention] Industrial Field of Application This invention relates to the structure of an adjustable door.

Problems with the Prior Art It required skill and effort to erect the door between the pillars so that the door could be opened and closed smoothly.

In addition, over many years, the width of the door may expand, or
There were some drawbacks, such as the attachment of the metal fittings becoming loose and the tip of the door hitting the metal fittings.

Purpose of the invention This invention was designed to enable smooth opening and closing of the door by accurately attaching the vertical frame of the door frame to the pillars of the building entrance when a new door is installed at the entrance of a building. The door can be completely housed within the door frame so that there is no gap between the door and the door frame, and the door can be easily installed even if the installation goes awry due to long-term use. The purpose of the adjustable door mounting is to provide a structure that allows modifications to be carried out very easily while ensuring smooth opening and closing of the door at all times.

EXAMPLES Below, description will be made based on the illustrated embodiments. Reference numeral 1 indicates a vertical frame, 2 a hinge, 3 a door, and 4 a metal fitting for a door holder.

The vertical frame 1 has a base piece 5 and a mounting piece 6 bent at a right angle from the base piece 5 so as to have an abbreviated cross-section.

A retaining piece 7 and a reinforcing piece 7a projecting from the attaching piece 6 at right angles are formed on the outer and inner surfaces of the intermediate portion of the mounting piece 6, respectively, and the retaining piece 7 is a part that accommodates the cutout of the outer wall edge. , the reinforcing piece 7a is a reinforcing portion of the mounting piece 6.

Also, a nail hole 20 is bored at the tip.

On the other hand, the screw hole 2 faces the base piece 5 of the vertical frame 1 on the hinge installation side.
1 is drilled, and a hinge 2 is fixed to the vertical frame 1 at this screw hole portion to pivotally connect the door 3 to the vehicle frame 1.

The door receiver has a hole 22 in the side frame 1 for inserting the latch part of the lock into the base piece 5 and a screw hole 23 for attaching it to the pillar.
is drilled.

A pair of opposing protrusions 8 are bent inward and protrude from the tip of the base piece 5 on the side opposite to the mounting piece 6. forming an internal space 11;
An adjustment screw hole 9 is drilled in the center of the bottom, into which an adjustment screw 10 is screwed, and an adjustment backing 12 that comes into contact with the tip of the adjustment screw 10 is built into the internal space 11. .

This backing 12 is formed to have a convex cross-section with a wide I-shaped base so that it can freely protrude from between the protrusions 8, 8, and can be engaged with the bent portion of the tip of the protrusion 8. A recess 13 communicating with the screw hole is bored.

On the back side of the projecting pieces 8, 8, that is, in the door mounting direction, a pair of protrusions 14, 14 are provided in a continuous manner on the protruding pieces 8, 8, and at the middle part of the inner surface of this protrusion 14, there is a triangular cross-section. A small locking protrusion 15 is provided to project and lock the cover 16.

In the door support section, a metal fitting 4 is further attached to the door stop portion of the vertical frame 1.

When attaching the door 3 to the pillar 17a via the vertical frame 1, as shown in FIG. Temporarily fasten the
Next, the screw 19 for attachment is screwed into the base piece 5.

In this case, if the tip corner A of the door 3 hits the tip B of the metal fitting 4 when the door 3 is opened and closed, the holder attached to the formwork 2 which has been fixed in advance to the column 17b of the door holder should come into contact with the tip B of the metal fitting 4. By screwing in the adjustment screw 10 of the screw hole 9 and pushing out the adjustment backing 12 and pressing the column 17a, the projecting piece 8 side of the formwork 1 on the hinge attachment side moves away from the column, and the formwork 1
rotates toward the door around the temporary fixing position 20.

The fulcrum C of the hinge 2 is adjusted so as to move toward the pillar 17a so that the corner A at the tip of the door 3 does not hit the tip of the metal fitting 4.

Thereafter, the nails 18 are completely driven into the pillars 17a and the screws 19 are tightened to fix the formwork 1 to the pillars 17a, and then a cover is fitted onto the projections 14 to hide the screws 10.

On the other hand, if the gap between the end corner A of the door 3 and the bracket 4 is too large, turn the adjusting screw 1o in the opposite direction to reduce the amount of protrusion of the adjusting backing 12, and then tighten the screw 19 further into the pillar 1.
9a, the formwork 1 can be moved around the temporary fixing position 20, and the fulcrum C of the hinge 2 can be moved in the direction of the door 3.

In addition, if the door has expanded over the years or has wobbled when installed, warm up the screw 19, remove the cover 16, and turn the adjustment screw 10 forward or backward to adjust the amount of protrusion of the adjustment backing 12. After adjusting the erection of the formwork 1 and the position of the hinge 2, tighten the screws 19 again to fix the formwork 1 to the pillars 17a.

In this way, the installation is corrected, but the adjustment backing 1
When the amount of protrusion of the hinge 2 is adjusted to be larger, the mounting piece 6 and the base piece 5 of the formwork 1 are deformed around the position of the nail 18 by the pressing force of the adjustment backing 12, and the position of the hinge 2 is moved. , prevent door rattling and interference with the frame.

In the past, when the amount of protrusion of the adjusting backing 12 was to be made smaller than when it was erected, the adjusting screw 10 was turned in the opposite direction to allow the adjusting backing 12 to be retracted, and then the screw 19 was further screwed in to lower the formwork 1. The mounting piece 6 and the base piece 5 are deformed by the tightening force of the screw 19 to move the position of the hinge 2.

This invention consists of the above-mentioned structure, and the door is attached through a vertical frame, and the vertical frame is adjusted by adjustment screws and adjustment backing in addition to the installation screws. This is a practical idea, as the installation is accurate and the installation can be easily corrected after many years of use.
