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, particularly 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. ,
Conventionally, a structure is known in which the axial center is moved up and down so that the upper blade can be finely moved in the axial direction.

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. However, the hinge of Japanese Utility Model Laid-Open No. Sho 60-22662 has a drawback that the door load is supported by the giboshi (decorative plug) on the upper end of the upper hinge, so it takes time and effort to weld the giboshi and support it 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. 56-11225.
Since the shaft cylinder structure of Japanese Patent No. 6 is only inverted upside down, it has the same drawbacks.

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. Structure of the Invention: The structure 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 protruding from the lower shaft cylinder (1), (4) ) Is the upper barrel (2)
The upper blade is more projecting, (5) is the shaft core, (6) is the upper support plate, and (7) is the lower support plate.

The lower blade (3) is attached to the pillar (8) and the upper blade (4) is attached to the door (9).

The upper support plate (6) has a disk shape having a diameter substantially equal to the diameter of the upper barrel (2) and has a holding piece (10) protruding to one side, and the holding piece (10) has an upper blade (4). A gap (11) having a width equal to the thickness of () is provided.

The upper support plate (6) is inserted into a gap having a thickness equal to that of the support plate (6) provided at a position near the upper end of the upper barrel (2), and the holding piece (10) of the support plate (6). It is fixed to the upper barrel (2) with the edge of the upper blade (4) sandwiched in the gap (11).

The lower support plate (7) has the same shape and size as the upper support plate (6), has a screw hole (12) in the center, and is attached to the lower barrel (1) in exactly the same manner as the upper support plate (6). ing.

Further, an adjusting screw (13) is screwed upward from the lower part in the center of the lower support plate (7).

A steel ball (14) is fitted on the top end of the shaft core (5), and immediately above the lower support plate (7) of the lower shaft cylinder (1), it penetrates through the wall of the lower shaft cylinder (1) and is stopped. A screw (15) is screwed on, and its tip reaches the adjusting screw (13).

(16) is a washer, (17) is a shaft cylinder cavity, (18) is a decorative cap, and (19) is a mounting screw hole.

When assembling the hinge of the present invention, first, the lower barrel (1)
The lower part of the shaft core (5) is inserted into the shaft cylinder cavity (17) of the above, then the washer (16) is fitted into the upper part of the shaft core (5), and then the upper shaft cylinder (2) is inserted into the shaft core (5). ). At this time, if there is a gap between the washer (16) and the upper barrel (2), loosen the adjusting screw (13) to lower the shaft core (5), and at the place where the gap has just disappeared, adjust screw (13). ), Screw in the set screw (15), and strongly apply the lateral pressure to the adjusting screw (13).

Assembled as above, and when there is no gap between the washer (16) and the upper barrel (2), screw the adjusting screw (13) to make a gap, then gently adjust screw (13).
Return to eliminate the gap.

Finally, the decorative caps (18) are fitted to both ends of the shaft cylinders (1) and (2) to complete the whole assembly.

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) are fitted to the upper barrel (2) and the lower barrel (1), respectively, and the upper and lower support plates (6) and (7) are respectively fitted to all of them. Since the circumference is supported by the peripheral wall of the shaft cylinders (1) and (2), the shaft core (5) is strong against the load in the longitudinal direction (that is, the vertical direction), and the support plates (6) and (7) are also supported. Since the holding piece (10) is fitted to the edges of the blades (3) and (4), the positions of the support plates (6) and (7) deviate from the shaft cylinders (2) and (1). There is no such thing.

That is, the upper support plate (6) and the lower support plate (7) are both strong to form a reliable support structure.

Next, after adjusting the height of the shaft core (5) with the adjusting screw (13) correctly as described in the above-mentioned assembly procedure,
Since the set screw (15) is screwed and the tip of the set screw (15) is pressed against the adjusting screw (13), the adjusting screw (13) is not loosened by the opening and closing vibration of the door (9).

Also, as described in the above-mentioned assembly procedure, the adjustment screw (1
If the gap between the upper barrel (2) and the washer (16) is removed by turning 3), the steel ball (14) 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 (16), the steel ball (14), the shaft core (5), The adjusting screw (13) and the lower support plate (7) are attached to 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 at only 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.

Effect of the Invention: Since the present 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 shaft cylinders (2) and (3), and the respective holding pieces (10) of the blades (3) and (4) are Since they are fitted to the edges, each support plate (6) (7) constitutes a good support,
Moreover, the position does not shift.

-Since the set screw (15) firmly fixes the adjustment screw (13), the adjustment screw (13) will not loosen due to the vibration caused by the opening and closing of the door (9), and the shaft core (5) will shift. 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.
