Abstract

The present invention relates to a hinge used for a swing door.

If the common hinge is used for a long time, the weight of the door and the hinge is worn down by the friction between the left and right wing contact point, the door sags downward, and the lower part of the door contacts the door frame, which causes inconvenience to use.

The hinge of the present invention relates to a hinge capable of raising the position of the door to the required height by simply adjusting the height of the hinge when the door sag.

Description

Height-Adjustable Hinge}

The present invention relates to a hinge used for a swing door, and representative hinges currently used for a swing door are the general hinge of FIG. 2 and the diaphragm hinge of FIG. 3.

The general hinge has the advantage of being firm and easy to handle, but when the hinge is worn down by long use or sags down by the weight of the door, the only way to lift the door by loosening the screw that secures the hinge to the door is to lift the door. The screwed hole and the new screw hole are adjacent to each other, making it difficult to fix the hinge with the screw again, and sometimes it is difficult to remove the screw because the screw is rusted or the cross or straight groove of the screw head is broken.

The diaphragm hinge can be adjusted by changing the quantity or thickness of the washers 15 shown in Fig. 3 to adjust the upper and lower positions of the door without loosening the screws that secure the hinge to the door, and if necessary, the door can be removed from the door frame or door without removing the hinge from the door frame or door. There is an advantage that can be removed, but the hinges must be purchased separately for the left and right for the door and the hinge is separated because the hinge is flowed down when the door is attached to the door because it is inconvenient to handle the woodworkers avoid using.

The technical task of the present invention is to take advantage of the hinge type hinge, remove the screw that secures the hinge and can adjust the position of the door up and down without going through the procedure of removing the hinge from the door, and simply remove the door from the door frame if necessary It is possible to make a hinge without the discomfort of the hinge, which can be distinguished from the left and right, which is an advantage of the general hinge, and is detached during the door opening work.

The basic positional relationship between the door, the door frame and the hinge used in the description of the present invention is as shown in Fig. 1 (a) and (b).

As shown in (a) (b) (c) and (d) of FIG. 4, the hinge can be height-adjusted and is fixed to the door frame 8 and attached to the door and rotated about the central axis 10. It consists of a central axis 10 having a rotary blade 9, the upper fixing protrusion 16 and the lower fixing protrusion 17 to the fixed blade cylinder 13 and the rotary wing cylinder 14 in Figure 4 As shown in (d), there is a central shaft hole 11 having a fixed blade fixing protrusion groove 18 and a rotary wing fixing protrusion groove 19.

There is a washer (15) used to adjust the height at the upper and lower connecting parts of the fixed blade and the rotary blade, and the method of adjusting the position of the rotary blade, that is, the height of the door by using the washer, is shown in Fig. 6 (a) (b) (c). As shown in

As shown in Fig. 7 (d), the angle between the fixed blade and the rotary blade is 180 degrees, that is, the door is opened wide or as shown in Fig. 8 (d), the angle between the fixed blade and the rotary blade is 0 degrees, That is, when the door is closed, the position (angle) of the fixed blade fixing protrusion groove 18 and the rotary wing fixing protrusion groove 19 do not coincide, so the central axis cannot be moved up and down, and the central axis can be pulled out and separated. none.

However, as shown in (d) of FIG. 9, when the fixed blade and the rotary blade form a constant angle, the positions of the fixed wing fixing protrusion groove 18 and the rotary wing fixing protrusion groove 19, that is, the angle coincide with each other, The lower fixing protrusion 17 can move up and down through the rotary wing fixing protrusion groove 19 to remove the central axis, and as shown in (a) (b) and (c) of FIG. The door can be adjusted up or down by adjusting it.

To adjust the position of the door up, first rotate the door to an angle where the central axis can be pulled out, remove the central axis of the hinge attached to the upper part of the door, remove the upper washer to the height to move and refit the central axis. Then remove the upper washer of the hinge attached to the lower part of the door in the same way and refit the central axis. Lift the door up and the door will move up the thickness of the removed washer. In this state, the center shaft is pulled up and the extracted washer is pushed into the lower washer position of the hinge, and the center shaft is inserted to adjust the position of the door.

When the fixing projection groove of the fixed blade and the fixing projection groove of the rotary blade are different from each other and pulled up to remove the central shaft, the lower fixing projection of the central shaft is caught by the rotary blade cylinder and the central shaft cannot be pulled out.

The angle where the position of the fixing projection groove of the fixed blade and the fixing projection groove of the rotary blade coincide, that is, the angle at which the central axis can be removed from the hinge, is determined as the open angle of the door, and when the door is closed, the central axis cannot be pulled out and the hinge cannot be removed. This makes it impossible for an outsider to remove the hinge and open the door.

In the drawings of the present invention, the upper fixing protrusions and the lower fixing protrusions are shown as two left and right, respectively, if necessary, the number of fixing protrusions may be increased or decreased or the arrangement angle may be changed.

Washers can be used in combination of a plurality of thin and the same thickness, or a plurality of different thickness.

If the hinge is worn down by long-term use and the door swings down and the door frame is inconvenient to use, it is easy to solve the problem by removing the washer at the top of the hinge and adjusting the height of the door upward. The height of the hinged hinge can be easily adjusted and the door can be easily separated from the door frame if necessary. .
