Description

[Detailed Description of Device] a. BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement in a hinge used for construction, in particular, a hinge in which two blades are hinged by inserting one shaft core into two upper and lower shaft cylinders.

B. 2. Description of the Related Art: In a so-called flag hinge or pivot hinge of a type in which two shaft cylinders penetrate one shaft core, by a screw applied to the shaft core or a screw screwed into the bottom of the shaft cylinder. ,
A structure in which an axial center is moved up and down so that the upper blade can be finely moved in the axial direction has been conventionally known.

For example, in the hinge of Japanese Utility Model Laid-Open No. 56-112256, when the shaft core is pushed up by the adjusting screw, the upper and lower shaft cylinder contact parts are separated and the load of the door is received only by the screw groove, so the load resistance is reduced. The hinge of Japanese Utility Model Laid-Open No. Sho 60-22662 has a drawback. Since the door load is supported by the giboshi (decorative plug) at the upper end of the upper hinge, it takes a lot of time to weld and install the giboshi and the hinge is supported when the door is opened and closed. There was a defect that the screw of the shaft loosened.

Further, Japanese Utility Model Laid-Open No. 63-51072 discloses the above-mentioned Japanese Utility Model Laid-Open No. 56-112256.
Since the shaft cylinder structure of the publication is only inverted upside down, it has the same drawbacks.

Further, in Japanese Utility Model Publication No. 47-29870, "a seat plate is inserted in the middle of the tubular portion above the flag hinge and the seat plate is welded and fixed to the inner surface of the tubular portion by its upper surface" is seen. However, this welding operation has a drawback that it requires a lot of labor and skill, and therefore the manufacturing cost becomes high.

C. Purpose of the invention: In a hinge with a vertically movable axial core, a strong and reliable support structure for supporting the load of the door is obtained, while preventing the screw from loosening due to vibration during use of the hinge,
The purpose is to supply reliable hinges at low cost.

D. Configuration of the Invention: The configuration of the present invention will be described with reference to the drawings. (1) is a lower shaft cylinder of a hinge, (2) is an upper shaft cylinder, (3) is a lower blade,
(4) is an upper blade, (5) is an axial center, (6) is an upper support plate, (7) is a lower support plate, (8) is a bottomed cap,
(9) is an upper bottom cap.

The lower blade (3) is on the pillar (10) and the upper blade (4) is on the door (1
It is attached to 1).

The upper support plate (6) has a disk shape having a diameter equal to that of the upper barrel (2), and is provided at a position near the upper end of the upper barrel (4) and has a gap equal to the thickness of the supporting plate (6). It is inserted in (12).

The lower support plate (7) has the same size and size as the upper support plate (6), has a screw hole (13) in the center, and in the same manner as the upper support plate (6), the gap ( 14) is attached.

Further, an adjusting screw (15) is screwed upward from below into a screw hole (13) at the center of the lower support plate (7).

A steel ball (16) is fitted on the top end of the shaft core (5), and is fixed immediately above the lower support plate (7) of the lower shaft cylinder (1) by penetrating the wall of the lower shaft cylinder (1). A screw (17) is screwed on, and its tip reaches the adjusting screw (13). The length of the fixing screw (17) is set so that the screw head does not project to the surface of the lower barrel (1) when the fixing screw (17) is completely tightened.

The lower bottomed cap (8) and the upper bottomed cap (9) are bottomed cylindrical caps made of metal or plastic, and have side walls (18) with longitudinal grooves (19). ) Is provided. The width of the vertical groove (19) is equal to the thickness of the base portion (20) of the blades (3) and (4), and the length thereof is equal to the length of the barrels (1) and (2).

Therefore, while fitting the blade base (20) into the vertical groove (19) of the caps (8) and (9), the caps (8) and (9) are externally fitted to the respective barrels (1) and (2). Can be made.

(21) is a washer, (22) is a shaft cylinder cavity, and (23) is a mounting screw hole.

To assemble the present hinge, first insert the lower part of the shaft core (5) into the shaft cylinder cavity (22) of the lower shaft cylinder (1), and then insert the shaft core (5).
The washer (21) is fitted into the upper part of the above, and then the upper barrel (2) is fitted onto the shaft core (5).

At this time, if there is a gap between the washer (21) and the upper shaft cylinder (2), loosen the adjusting screw (15) and set the shaft core (5).
Lower and adjust the adjustment screw (1
5) Stop, screw in the fixing screw (17), and adjust the adjustment screw (1
5) Apply strong lateral pressure and fix.

Further, when there is no gap between the washer (21) and the upper shaft cylinder (2) when the upper shaft cylinder (2) is externally fitted to the shaft core (5), the steel at the top end of the shaft core (5) Since the ball (16) is not hitting the upper support plate (6), the adjustment screw (15)
Turn the screw to make a gap, then gently return the adjusting screw (15) to eliminate the gap.

Next, tighten the fixing screw (17) until its head sinks from the surface of the lower barrel (1), and then the upper and lower caps (8) with bottoms.
(9) is fitted into the upper and lower barrels (1) and (2), respectively, and the assembly is completed.

E action: Since the hinge of the present invention is configured as described above, it has the following action.

The upper support plate (6) and the lower support plate (7) have a gap (12) (1) between the upper barrel (2) and the lower barrel (1), respectively.
Since it is fitted in 4) and the entire periphery is supported by the cylinder wall of the shaft cylinder (1) (2), it is strong against the load in the longitudinal direction of the shaft core (5) (that is, the vertical direction), Also, each support plate (6)
Since the outer periphery of (7) is surrounded by the side walls (18) of the caps (8) and (9), its position does not shift.

That is, the upper support plate (6) and the lower support plate (7) are both rigid and constitute a reliable support structure.

Next, as explained in the above-mentioned assembly procedure, after correctly adjusting the height of the shaft core (5) with the adjusting screw (15), the fixing screw (17) is screwed in, and the tip thereof is adjusted with the adjusting screw. Since it is pressed against (15), the adjustment screw (15) will not loosen due to the opening / closing vibration of the door (11).

Also, as described in the above-mentioned assembly procedure, the adjustment screw (1
If the gap between the upper barrel (2) and the washer (21) is eliminated by turning the (5), the steel ball (16) at the top end of the shaft core (5) will move downward as the shaft core (5) descends. Since it comes in contact with (6) and descends while supporting it, the load of the door (9) is applied to the lower barrel (1) through the washer (21) and from the steel ball (16) to the shaft core (5). , Adjusting screw (1
5), the one passing through the lower support plate (7) and hanging on the lower barrel (1).

Therefore, compared with the conventional two-axis hinge, which has a structure in which the load is supported only at one place only at the joint of the upper and lower shaft cylinders, or a structure where the load is supported only at one place at the steel ball at the top of the shaft core,
Since the load is dispersed in the hinge of the present invention, the load bearing strength is large.

F. Effect of the invention: Since the invention is constructed and operates as described above, it has the following effects.

The upper support plate (6) and the lower support plate (7) are both supported at their peripheral edges by the barrels (2) and (3), and are respectively supported by the side walls (18) of the bottomed caps (8) and (9). Since it is enclosed, it not only holds the load completely, but also does not shift its position.

In addition, since welding work is not required, work can be performed easily and can be supplied at low cost.

Since the fixing screw (17) firmly fixes the adjusting screw (15), the adjusting screw (15) will not loosen due to the vibration generated by opening and closing the door (9), and therefore the shaft core (5) will be displaced. It won't go down.

-Since the load of the door (9) is distributed to the joint of the vertical shaft cylinders (2) and (1) and the steel ball (14) at the top end of the shaft core (5), the load strength of the hinge becomes large, and therefore Withstands long-term use.
