[Detailed description of the invention] [Industrial field of application] The invention relates to a hinge that allows the mounting position of a door, etc. to be adjusted up and down, and more specifically, it is a hinge that can be attached to a door or the like to raise and lower a shaft pin. Regarding hinges.

[Conventional technology] Hinge with vertical adjustment structure using screws has traditionally been
A variety is offered. Although it is not a wing hinge, for gates and pivot type hinges, for example,
-3561, No. 54-3562, and Japanese Utility Model Application Publication No. 57-111965, a male thread is screwed into a female thread groove provided on the inner circumferential surface of the lower opening of a lower bearing part of a gate or pivot. A hinge is disclosed that has a structure in which the door is pushed up and adjusted up and down depending on the amount of contact with the lower end of the pin.

In addition, Japanese Patent Publication No. 52-24189 discloses that the door can be adjusted up and down by relatively pushing down the shaft pin depending on the amount of threading of the male screw in the female thread groove on the inner peripheral surface of the upper opening of the upper bearing part. A hinge having a structure is disclosed.

Furthermore, regarding the wing hinge,
No. 29413 and Japanese Utility Model Application Publication No. 56-112256 disclose a structure in which a male thread is screwed into a female thread groove on the inner circumferential surface of a lower opening of a lower bearing portion for vertical adjustment.

Furthermore, as shown in Japanese Utility Model Application No. 58-195764, one of the applicants for this utility model registration provided a female thread groove on the inner circumferential surface of the opening of each bearing part of the blade hinge, and screwed the male thread of the prosthetic star. With this structure, both the left-hand hinge and the right-hand swing door can be adjusted vertically.

[Problems to be solved by the invention] However, the hinges of each of the above vertical adjustment structures,
In either case, a female thread groove must be formed on the inner circumferential surface of the bearing portion or the inner cylinder thereof, which inevitably increases manufacturing costs.

In particular, the threaded connection between the female thread groove and the male thread sometimes loosened due to rotation of the shaft pin or vibrations when opening and closing the door.

However, the present invention has been further developed in view of the above circumstances, and allows vertical adjustment of the blade hinge by tapping without providing a female thread groove.
The purpose is to reduce the amount of adjustment slack.

[Means for Solving the Problems] A hinge according to the present invention for achieving the above object has a shaft pin inserted into the bearing portions of a pair of left and right blades, and at least one opening at the upper and lower ends of each bearing portion. A collar member made of a tapping-capable material and having a hole without a female thread groove is fixed inside, and the male thread member is brought into contact with the end of the shaft pin by tapping the male thread member into the hole of the collar member. It is characterized by its configuration.

[Function] If it is necessary to adjust the mounting position of the door in the vertical direction with the pair of left and right vanes fixed to the main body and the door, for example, a male screw member is tapped into a hole in the collar member of the lower bearing part. The hole of the collar member which does not have a thread groove is tapped with a female thread groove formed by the male thread member. Along with this tapping, the male threaded member spirals and pushes up the shaft pin, so that vertical adjustment is performed.

[Example] Figure 1 is an exploded perspective view of a hinge according to the present invention;
Figure 2 is a sectional view showing the vertical adjustment state from the front;
FIGS. 3 and 4 are sectional views of main parts showing the state before and after left and right adjustment. The hinge shown here is a wing hinge that can be adjusted laterally.

In the figure, 1 and 2 are vane plates, 3 and 4 are bearing parts of the vane plates 1 and 2, 5 is a shaft pin inserted into each bearing part 3 and 4, and 6 is integrally projected from approximately the middle of the shaft pin 5. 7 is a projection provided near the flange 6, and 8 is a receiving groove formed by cutting out the upper end opening of the blade plate 1 to engage with the projection 7.

Therefore, a collar member 10, 1 is provided inside at least one opening 3a or 4a of the bearing portions 3, 4.
1 is fixed, and the holes 12 of the collar members 10, 11,
13 has potato screws 14 and 15 as male screw members.
is tapped. The collar members 10, 11
is an inner cylindrical portion 10 into which the openings 3a and 4a are inserted;
a, 11a, and flange portions 10b, 11b that abut the opening end surfaces 3b, 4b, and are fixed by spot welding or the like when inserted into the bearing portions 3, 4.

The collar members 10 and 11 have a hollow hole structure without providing thread grooves in the holes 12 and 13. The collar members 10 and 11 may be made of any material that can be tapped, preferably a material such as steel that is not subjected to heat treatment such as quenching. If the door is lightweight, metal materials such as aluminum or zinc alloy can also be selected. In any case, the blade plate 1,
2 and the bearing parts 3 and 4, the strength of these parts is not affected.

Vertical adjustment based on the above configuration is performed for each blade plate 1, 2.
When fixed to the main body A and a door (not shown) and inserted into the shaft pin 5, the protrusion 7 engages in the receiving groove 8 and the shaft pin 5 is prevented from rotating. Just screw them together. The potato screw 14 is tapped into the hole 12 of the collar member 10 and screws forward by a distance α, and when its tip surface 14a pushes up the lower end 5a of the shaft pin, the collar 6 pushes up the upper blade plate 2 by a distance α. Therefore, the distance α is adjusted up and down on the door side.

A left-right adjustment mechanism can be added to the hinge of the above embodiment. In addition to the blade plate 1, a seat plate 20 is provided, and the seat plate 20 is formed with a plurality of countersink holes 21 for set screws, screw holes 22 for adjusting screw members, and screw holes 23 for connection. Connection screw hole 2 on one side of the seat plate 20
A plurality of male screw portions 27 of the adjusting screw member 24 are screwed into the screw portion 2 . The adjustment screw member 24 has a flange 25 projecting in the middle, and a large-diameter head 2 in the upper half of the flange 25.
6, and a male threaded member 27 is formed in the lower half. Further, a connecting screw 28 for connecting to the vane plate 1 is screwed into the connecting screw hole of the seat plate 20. In addition, 29 is a set screw of the seat plate 20, 30 is a round hole of the wing plate 1, 3

According to the above-mentioned left-right adjustment structure, the dug groove B of the main body A
The seat plate 20 is fixed in the dug hole C deeper than that with a set screw 29. In this state, the head 26 protrudes from the upper surface of the seat plate 20 with the flange 25 of the adjustment screw member 24 in close contact with the head 26, so the round hole 30 of the wing plate 1 is engaged with the head 26, The connecting screw 28 is screwed into the connecting screw hole 23 from the connecting screw countersunk hole 31 and attached. In this case, the connecting screw 28 is left loose, and after the door-side vane plate 2 is attached via the shaft pin 5 as described above, the left-right adjustment is performed.

That is, in the above state, the adjusting screw member 24 is rotated counterclockwise, for example, to project the flange 25, and with the wing plate 1 pressed against the flange 25, left and right positioning is performed. After positioning, connect screw 2
When the blade plate 1 is tightened to the seat plate 20 at step 8, the blade plate 1 is fixed and adjusted in a raised state by the collar portion 25.

FIG. 5 is a partial perspective view showing another embodiment of the hinge blade plate according to the present invention, and the same reference numerals as in FIGS. 1 to 4 indicate equivalent parts.

Thus, a round hole 32 is provided in the center of the upper blade plate 2, and a receiving groove 33 is cut out in the lower end opening. In this case, since each of the blade plates 1 and 2 can have the same structure, by engaging the countersinks 31 from the front and back sides, it is possible to create a vertical tapping adjustment structure for the blade hinge for a left-hand door or a right-hand door. .

In the above embodiment, the lower collar member 10
Although the structure for adjusting has been described, even if the upper collar member 11 is screwed and adjusted, the same vertical adjustment effect can be obtained by pressing down the set screw 15 to the upper end 5b of the shaft pin.

Moreover, the inner cylinder part 10 is used as the collar members 10 and 11.
Although the structure consisting of a, 11a and flange parts 10b, 11b has been illustrated and explained, the inside of the openings 3a, 4a of the bearing parts 3, 4 are made into a dug structure, and only the portion corresponding to the inner cylinder part is inserted and fixed. design changes are possible.

Furthermore, screws 14 and 15 are also used as male thread members.
is shown as an example, but other screws that can be tapped may also be used in the same way.

[Effect of the invention] As explained above, according to the hinge according to the invention, a hole made of a material that can be tapped and having no internal thread groove is provided inside at least one opening at the upper and lower ends of each bearing portion of the blade plate. Since the provided collar member is fixed, the door etc. can be adjusted up and down by tapping the male threaded member into the hole of the collar member and bringing the male threaded member into contact with the end of the shaft pin. Therefore, it is not necessary to form a female thread groove in the bearing part in advance, which simplifies the manufacturing process, and also allows for tight screw engagement using the biting force of tapping, making it easy to adjust the position over time. I was able to get rid of my insanity.
