Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hinge capable of being aligned with a door entrance when the door is attached to the entrance of a building.

(Prior Art) When attaching a door to an entrance of a building, a mounting hole for a fixed-side blade of a hinge is dug in a pillar or a wall surface, and a mounting hole for a vane on the door side is dug in a door.

Therefore, even if the door and the entrance are manufactured with high accuracy,
If the depth of the mounting seat hole is incorrect or the positional relationship of the mounting seat hole between the pillar side and the door side is displaced, the positional relationship between the door and the inlet is also displaced.

For example, as shown in FIG. 9, when the door 1 is attached to the entrance 2 as shown by an imaginary line 1 ', the hinge 3 causes the clearance C ₁ between the floor FL and the door 1 lateral clearance in the vertical direction of the clearance C _2, and the inlet 2 and the door 1 and the door 1
C ₃ must be adjusted.

A hinge that can be separated via a conventional tongue (Japanese Patent Laid-Open No.
No. 36884) will be described with reference to FIGS. 15 to 18, the side screw operation hole 5 is formed in the door side vane plate 4 shown in FIG.
As shown in FIG. 16, the tongue piece 8 rotatably provided on the fixed side blade plate 9 via the shaft portion 10 is inserted into the door side blade plate 4, and the tongue piece is inserted. The side screw operation hole 5'and the center operation hole 6'provided on the piece 8 are aligned with the side screw operation hole 5 and the center operation hole 6 of the door-side vane plate 4, and side screws and center screws not shown in these holes are provided. To connect the two.

And by adjusting the side screw and the central screw,
As shown in FIG. 17, the tongue piece 8 can be moved by an angle θ in the hole provided in the door-side vane plate 4, and the gap C ₃ shown in FIG. 9 is adjusted.

The tongue piece 8 is integrally attached to the shaft 11 as shown in FIG. 12 is a collar fitted on the shaft 11. 15th
As shown in FIG. 17, the width W of the door-side blade 4 shown in the figure is narrowed by t dimension with respect to the thickness T of the door 1, and the outer surface of the door 1 has the width W of the door-side blade 4. The mounting seat hole is not exposed so that the appearance of the door 1 is not spoiled.

The hinge shown in FIG. 19 (Japanese Utility Model Laid-Open No. 58-195763) is a female screw formed at the end of the support cylinder 14 by inserting two blade plates 13 integrally provided with the support cylinder 14 into a shaft 15. Adjusting screw 16 to 17
Are screwed together, and both ends of the shaft 15 are pressed and held by the end surface of the adjusting screw 16.

Then, the positional relationship between the two blade plates 13 with respect to the shaft 15 is adjusted by adjusting the screwing amount of the adjusting screw 16, as shown in FIG.
The gap between C ₁ and C ₂ is adjusted.

(Problems to be Solved by the Invention) In the above-mentioned conventional hinge, the hinge shown in FIGS. 15 to 18 has the tongue piece 8 and the shaft 11 integrally connected, so that the tongue piece 8 is fixed. It is difficult to attach it to the side vane plate 9, and there is a problem in terms of mass productivity.

Also, since the shaft 11 is rotated by opening and closing the door, for example, as shown in FIG. 19, both ends of the shaft 11 are pressed and held by the adjusting screws 16 to adjust the clearance between C ₁ and C ₂ shown in FIG. Even if it can be done, the adjustment screw 16 is loosened due to the rotation of the shaft 11,
There is a problem that the gaps C ₁ and C ₂ cannot be maintained for a long time.

Next, in the conventional example shown in FIG. 19, the adjusting screw 16 is
Since the shaft 15 is screwed to and rotates with the support cylinder 14 when the door is opened and closed, and the shaft 15 does not rotate when the door is opened and closed, friction occurs between the end surface of the adjusting screw 16 and the tip of the shaft 15. There is a problem that the tightening of the adjusting screw is loosened and the gaps C ₁ and C ₂ shown in FIG. 9 cannot be maintained for a long period of time.

The present invention provides a hinge that facilitates the attachment of the tongue piece and the fixed-side vane and can maintain the positional relationship between the door and the entrance for a long period of time.

(Means for Solving the Problem) Means according to the present invention for solving the above problem is a hinge in which a fixed-side blade plate and a door-side blade plate are separable via a tongue piece. Two tongue pieces are formed on the plate by vertically separating two threaded cylinders with their axial centers aligned and the one end is provided with a tongue piece having a supporting cylinder formed at a height lower than the height of separation of the cylinders. The support cylinder of the tongue is positioned between the upper and lower shaft cylinders so that the axes are aligned with each other, and the shaft is inserted through the upper and lower shaft cylinders and the support cylinder of the tongue, and a concave hole into which the tip of the shaft fits is formed at one end. The adjusting screw is screwed from the outer end of the shaft cylinder, and both ends of the shaft are fitted into the recessed holes for crimp support, and between the end faces of the adjusting screws in the crimp supported state of the shaft, the tongue support tube It is characterized in that it is slightly smaller than the height.

(Operation) With this configuration, when assembling the tongue piece and the fixed-side vane plate, position the support tube of the tongue piece between the two shaft cylinders, insert the shaft, and insert the adjusting screw into the shaft cylinder. It is performed by screwing from the outer end.

The shaft is not integrated with the support cylinder of the tongue by being fitted into the recessed hole of the adjusting screw and crimping and supporting both ends of the shaft. The state is maintained.

Also, in this crimping support state, the gap between the end faces of the adjusting screw is made slightly larger than the height of the supporting cylinder of the tongue piece, so even if both ends of the shaft are strongly tightened with the adjusting screw, the supporting cylinder is tightened. I can't.

As a result, the tongue is rotated lightly when the door is opened and closed, and the adjustment screw is not loosened, and the shaft maintains its state for a long period of time due to the strong tightening force of the adjustment screw.

(Example) Hereinafter, one example of the present invention will be described in detail.

In FIG. 1 and FIG. 2, the fixed side vane plate 18 is integrally provided with two shaft cylinders 20 each having an internal thread 19 cut on the inner surface thereof so that their axial centers coincide with each other and are vertically separated from each other. 21 is a shaft, 22 is a barrel

Reference numeral 27 denotes a tongue, and a support cylinder 28 is integrally provided at one end of the tongue, and the inner diameter of the support cylinder is sized to insert the shaft 21. As shown in FIG. 1, the height H of the support cylinder 28 is such that both ends of the shaft 21 are fitted into the recessed holes 26 of the adjusting screw 22 and are crimped and held by the tightening force of the adjusting screw 22. Is slightly smaller than the end face interval l ₁ of the adjusting screw 22 of. Thus, the height H of the support cylinder 28 and the length l _{2 of the} shaft 21 are
Also, the depth l ₃ of the recessed hole of the adjusting screw 22 is determined. Tongue
Both side operation holes 29 and central operation hole 30 are formed in 28.
Reference numeral 31 is a collar having a slit 32 formed therein. Reference numeral 33 is a door-side vane, and protrusions 34 and 35 are formed on both sides. 36
Is a tongue piece insertion hole opened to the side of the protrusion 35. 37 is side screw
The operation holes of 39 and 38 are the operation holes of the central screw 40, and when the tongue piece 27 is inserted into the tongue piece insertion hole 36, both side operation holes 29 opened in the tongue piece 27 and the center of the hole in the center operation hole 30. Are opened to match.

To explain this door side vane 33 in more detail,
In FIGS. 3 to 5, the protrusions 34, 35 and the mounting holes 41 provided on both sides of the door side vane plate 33 are the protrusions 34, 35 and the mounting holes even when the door side vane plate 33 is turned upside down. It is provided in a rotationally symmetrical position so that 41 overlaps at the same position. The width W between the end faces of the protrusions 34 and 35 is set to be substantially equal to the height T of the door. As shown in FIGS. 4 and 5, a projection 42 is formed on the back surface of the door-side vane 33, and the projection 42 is screwed with the side screw 39 shown in FIG. Hole
A screw hole 44 into which the 43 and the central screw 40 are screwed is provided. As shown in FIGS. 6 and 7, the tongue insertion hole 36
Has a hole with one side inclined.

The operation of this embodiment having the above-mentioned configuration will be described below.

First, the assembling of the tongue piece 27 and the fixed side vane plate 18 will be described with reference to FIG. 2. The collar 31 is inserted into the support cylinder 28 and inserted between the shaft cylinders 20 in the direction of the arrow, and the shaft cylinder 20 and the support cylinder are supported. The shaft 21 is inserted with the centers of the cylinders 28 aligned. Next, adjust screw 22
Is screwed in from the outer end of the shaft cylinder 20, and both ends of the shaft 21 are fitted into the recessed holes 23 and tightened to firmly crimp and support both ends of the shaft 21.
Then, the cap 25 is screwed onto the barrel 20. This makes the tongue
27 is attached to the stationary side vane plate 18. Then, insert the tongue piece 27 into the tongue piece insertion hole 36, and insert the side screw 39 from the front side of the door side vane plate 33 and the center screw 40 from the back side, respectively.
The tongue piece 27 and the door-side blade 33 are screwed into the screws 3,44, and are joined together.

In FIG. 1, even if the adjusting screw 22 is strongly tightened and both ends of the shaft 21 are strongly crimped, the gap l ₁ between the end faces of the adjusting screw 22 is slightly larger than the height H of the support cylinder 28. twenty two
The support cylinder 28 is not tightened by tightening. Therefore, the tongue piece 27 and the end surface of the adjusting screw 22 are in light contact with each other, and the tongue piece is rotated around the shaft 21 with a light force. Also, the tightening force of the adjusting screw 22 is
It is held by the tightening force of the shaft 21.

In this way, even if the tongue 27 rotates with the door, the adjustment screw 22 will not be loosely tightened.

Next, for the adjustment of C ₁ and C ₂ shown in FIG. 9, a tool is inserted through the through hole 26 of the cap 25, the tool is attached to the hexagonal hole 24 of the adjusting screw 22, and the adjusting screw 22 is turned up and down. As a result, the tongue piece 27 moves up and down along the slit 32 of the collar 31 between the shaft cylinders 20 and the door side vane plate 33 also moves up and down to adjust the C ₁ and C ₂ gaps of the door 1.

Then, after the adjustment is completed, the adjusting screw 22 is strongly tightened. Next, for example, as shown in FIG. 10, the fixed-side blade plate dug in the pillar 45.
Since the mounting holes of 18 are inaccurate, it is necessary to adjust the clearance C ₃ when the door is mounted like a door 1'1 '. In this case, open like the door 1 ″ and adjust as follows.
In the figure, from the front side, using the tool 46, insert the tool 46 from the side screw 39 and the operation hole 38 and rotate the central screw 40,
The tongue piece 27 is moved within the tongue piece insertion hole 36 (see FIG. 17).

Next, as shown in FIG. 11, the thickness T of the door 1 and the protrusion
Since the distance W between the end faces of 34 and 35 is substantially equal, and the projecting portions 34 and 35 and the mounting hole 41 are rotationally symmetrical, the mounting seat hole dug in the door 1 is a projection fitting portion on the front and back of the door 1. 50 is cut. Then, when the door-side vane plate 33 is fitted, the end surface of the projecting portion 34 is exposed with the surface of the door 1 with a feeling of unity and does not impair its appearance. Even if the door side vane plate 33 is turned upside down, the door side vane plate 33 is attached to the mounting seat surface 48, the protrusions 34 and 35 are attached to the protrusion fitting portion 50, and the protrusion 42 (FIG. 4). Fits on the mounting seat surface 49.

When the door-side vane plate 33 is turned upside down in this way, for example, as shown in FIG. 13, when the room A is in the direction of arrow A, the door 1 opens outward. Therefore, a mounting seat hole is dug in the door 1 on the outside of the door 1 leaving a thickness t.

However, as shown in FIG. 14, when the door 1 for inward opening is brought into the field, there is a disadvantage that the mounting surface of the door 1 cannot be mounted because it is digging in the opposite way.

Even in such a case, as shown in FIG. 11, it can be dealt with by providing a mounting seat hole regardless of whether the door is open inward or outward and reversing the top and bottom of the door-side vane plate 33. That is,
As shown in FIG. 12, the protrusion 35 with the tongue insertion hole 36 opened,
According to the insertion direction of the tongue piece 27 of the fixed side vane plate 18 fixed to the pillar 46, select the top and bottom of the door side vane plate 33, and attach the door side vane plate 33 to the mounting seat hole dug in the door 1. Good.

(Effects of the Invention) As described in detail above, according to the present invention, the center of the shaft cylinder provided on the fixed side vane plate and the support cylinder provided on the tongue are aligned with each other, and the shaft is inserted to adjust the shaft Since both ends are pressed and supported, the tongue piece and the fixed side blade plate can be easily assembled.

In addition, since the gap between the end faces of the adjusting screw is made slightly larger than the height of the support tube of the tongue with the adjusting screw crimping and supporting both ends of the shaft, the tongue rotates slightly and the adjusting screw loosens. Even if the door is opened and closed for a long period of time, no crease is generated in the gap between the door and the entrance.
