[0003]

As described above, various proposals have been made in the past, but a simple structure generally has a poor appearance, a single action, and requires a lot of skill for adjustment. It was In addition, the complicated structure has a wide variety of actions, and the effect is good, but the complicated mechanism causes the adjustment effect to disappear immediately when the door is heavily used, and the readjustment is required. was there.

[0004]

According to the present invention, a door blade is inserted into a bracket through a door blade insertion gap of the bracket,
The opening notch of the door blade is externally fitted to the neck groove of the adjusting screw, the fixing screw is inserted into the long hole of the door blade, and the fixing screw is screwed into the fixing screw hole on the bottom surface of the bracket to fix the fixing. The door and the blade are fixed to the bracket with screws and adjusting screws. In addition, the same bracket is pushed open by pressing the same bracket by making the outer width of the bracket equal to the recessed width of the door and by winding the shaft cylinder so that the door blade protrudes in the diameter direction of the shaft cylinder. Also, it can be used for both the opening door and the door.

[0005]

The functioning hinge of the present invention is mounted and used as follows. First, make an open cut of the same size as the adjustment bracket on the indented surface of the hinged stile of the door, and fix the bracket in the open cut with the bracket mounting screw.
Next, insert the hinged door blade into the bracket through the blade groove of the bracket, and insert the door blade into the bracket while fitting the open notch of the blade into the neck groove of the adjusting screw. At this time,
Adjust the adjusting screw so that the door blades are parallel to the bottom of the bracket. Next, the fixing screw is inserted into the fixing screw hole through the long hole of the door blade and screwed, and the door blade is crimped and fixed to the upper edge of the side wall of the bracket by the adjusting screw neck groove and the fixing screw. When adjusting the inclination of the door blade, if the two fixing screws are loosened and the adjusting screw is screwed, the adjusting screw moves up and down, so that the door blade makes a seesaw motion with the upper edge of the side wall as a fulcrum. Therefore, if the fixing screw is tightened again at the position where the door blade has moved as much as necessary, the door blade is fixed at that position.
Next, in order to change the door opening / closing property, the door blade is once pulled out from the adjustment bracket, the blade is turned over, the blade is inserted into the blade groove from the opposite side of the bracket, and the same adjustment as above is performed. In addition, since the pillar blade has a restriction on its shape, another pillar blade is used when the opening hand is changed. The other column blade is mirror-symmetrical to the column blade shown.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to the drawings. (1) is a door, (2) is a pillar, and (3) is a hinge. An open cut (6) for accommodating the adjustment bracket (5) is cut out in the recessed surface (4) of the door (1). Depth (t) of the open cut (6)
Is equal to the height (H) of the side wall of the bracket (5). The bottom of the open cut (6) is provided with a shallow excavation (7) and a deep screw receiving hole (8) at the center of the shallow excavation (7). The shallow dug (7) and the deep screw receiving hole (8) are for accommodating the tips of the fixing screw and the adjusting screw, respectively, as described later.

Next, the hinge (3) has a pillar blade shaft cylinder (10) protruding from the pillar blade (9), a door blade shaft cylinder (12) protruding from the door blade (11), and upper and lower shaft cylinders ( 12) (10)
It consists of a shaft core (13) which penetrates through. The bracket (5) has a U-shaped cross section and is bent upward at right angles on both sides in the longitudinal direction to form side walls (14). The hinges (3) are formed at the upper ends of the side walls (14). A blade groove (15) for inserting the door blade (11) is provided. The blade groove (15) is open upwards, leaving short projecting pieces (16) on both sides thereof. The protruding piece (16) serves as a guide when inserting the door blade (11) into the blade groove (15) and prevents the door blade (11) from rising.

An adjusting screw hole (17) is provided at the center of the bottom surface of the bracket (5), and an adjusting screw (18) projects into the bracket (5) through the adjusting screw hole (17). The outer diameter of the head portion (19) of the adjusting screw (18) is made smaller than the outer diameter of the screw portion (20), and the head portion (1
A neck groove (21) having a width slightly larger than the thickness of the door blade (11) is provided between the screw portion (9) and the screw portion (9).
When the door vane (11) is fitted into the bracket (5), the open notch (22) of the door vane (11) is externally fitted into this neck groove (21).

On the bottom surface of the bracket (5), in addition to the central adjusting screw hole (17), mounting screw holes (23) are arranged vertically and horizontally symmetrically with respect to the adjusting screw hole (17). And a fixing screw hole (24). The fixing screw hole (24) is positioned such that the fixing screw hole (24) overlaps with the long hole (25) of the door blade (11) when the door blade (11) is inserted into the bracket (5). There is.

Next, the door blade (11) is made to fit the size of the blade groove (15) of the bracket (5) by slightly narrowing the blade portion to be inserted into the bracket (5) vertically. Further, an open cut (22) opened outward is horizontally provided at the center of the vertical length of the door blade (11), and when the door blade (11) is inserted into the bracket (5). ,
The open notch (22) is the neck groove (21) of the adjusting screw (18).
Mating outside. Also, the long hole (25) has an open cut (22).
Are provided at equal distances above and below, parallel to the open cut (22). Therefore, the door vane (11) is fitted with the bracket (5).
The slotted hole (25) and the fixing screw hole (24) always overlap with each other, regardless of which side is inserted.

After the door blade (11) is inserted into the adjusting bracket (5), the fixing screw (26) is fixed by the fixing screw (2).
It is for fixing the door blade (11) to the bracket (5) by inserting and screwing 6) into the fixing screw hole (24) of the bracket (5) through the long hole (25). When fixed in this manner, the back surface of the door blade (11) is pressed against the upper edge (27) of the side wall (14) of the bracket (5). Therefore, the upper edge (27) of the side wall (14) acts as a fulcrum for the seesaw movement of the door blade (11).

[0012]

The present invention has the following features since it has the structure and operation as described above. (A) The adjustment bracket (5) is also left-right handed and convenient to use. In particular, if the door (1) with the adjustment bracket (5) attached is delivered to the construction site, the door blade (11) is replaced at the site according to the opening of the door (1), and the door is adapted to the door. You don't need to change it because you get it. (B) Since the adjustment bracket (5) is dug into the recessed surface of the door and has no protrusions, it does not damage the fittings during integrated storage and transportation of the doors and does not impair the commercial value. . (C) When adjusting the degree of closing of the door, the upper edge of the side wall of the bracket serves as a good fulcrum for the seesaw movement of the blades, so the adjustment can be performed reliably and easily. (D) The structure is simpler than that of conventional adjustment hinges,
Moreover, since the number of constituent parts is small, not only is it easy to manufacture and can be supplied inexpensively, but it is also easy to adjust and there are few failures.
