Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a hinge that enables alignment between a door and an entrance when the door is attached to the entrance of a building.

(Prior Art) When attaching a door to the entrance of a building, a seat hole for attaching the fixed side wing plate of the hinge is dug in a pillar or wall surface, and a seat hole for attaching the door side wing plate is dug in the door.

Therefore, even if the door and entrance are manufactured with high precision, if the depth of the mounting seat hole is inaccurate or the positional relationship of the mounting seat hole between the pillar side and the door side is misaligned, the door and the door The positional relationship with the entrance will also shift.

For example, as shown in FIG. 9, when the door l is attached at an angle of 1° from the entrance 2 to the imaginary line, the hinge 3 creates a gap C between the floor FL and the door l at the entrance 2. It is necessary to adjust the vertical clearance C2 between the entrance 2 and the door l, and the horizontal clearance C3 between the entrance 2 and the door l.

A hinge that can be separated via a conventional tongue piece (Japanese Patent Application Laid-Open No. 1983-1999-
36884) with reference to FIGS. 15 to 18. The door side blade plate 4 shown in FIG. Insert the tongue piece 8 rotatably provided on the fixed side blade plate 9 via the shaft part 10 into the door side blade plate 4, and connect the side screw operation hole 5° provided in the tongue piece 8 with the center operation hole. The hole 6' is aligned with the side screw operation hole 5 and the center operation hole 6 of the door side blade plate 4, and a side screw and a center screw (not shown) are inserted into these holes to connect them.

Then, by adjusting the side screws and the center screw, the tongue piece 8 can be moved by an angle θ within the hole provided in the door side slat 4 as shown in FIG. 17, and the gap C3 shown in FIG. 9 can be adjusted. I try to do that.

Further, the tongue piece 8 is integrally attached to the shaft 11 as shown in FIG. 12 is a collar fitted into the shaft 11. The width W of the door side slat 4 shown in FIG. 15 is narrowed by seven dimensions with respect to the thickness T of the door l, as shown in FIG. The mounting seat hole 4 is not exposed so as not to spoil the appearance of the door 1.

The hinge shown in FIG. 19 (Japanese Utility Model Publication No. 58-195763) has two blade plates 13 integrally provided with a support tube 14.
An adjustment screw 16 is inserted into the shaft 15 and screwed into a female thread 17 formed at the end of the support cylinder 14, and the end surfaces of the adjustment screw 16 clamp and press both ends of the shaft 15.

Then, the positional relationship of the two blade plates 13 with respect to the shaft 15 is adjusted by the screwing amount of the adjustment screw 16, and the gap between C, C, and 4 shown in FIG. 9 is adjusted.

(Problems to be Solved by the Invention) Among the conventional hinges shown in FIGS. 15 to 18, the tongue piece 8 and the shaft 11 are integrally connected, so that the tongue piece 8 is fixed. It is difficult to attach it to the side blade plate 9, and there is a problem in terms of mass production.

Moreover, since the shaft 11 is rotated by opening and closing the door, for example, as shown in FIG. 19, by pressing and clamping both ends of the shaft 11 with adjustment screws 16, the gap between cl and c2 as shown in FIG. 9 can be adjusted. Even if this is done, there is a problem that the adjustment screw 16 becomes loose due to the rotation of the shaft 11, and the gaps C], , C2 cannot be maintained for a long period of time.

Next, in the conventional example shown in FIG. 19, the adjustment screw 16 is screwed into the support tube 14 and rotates together with the support tube 14 when the door is opened and closed, while the shaft 15 is rotated when the door is opened and closed. Since it does not rotate, friction occurs between the end face of the adjusting screw 16 and the tip of the shaft 15, and the tightening of the adjusting screw becomes loose, making it impossible to maintain the gap C3 shown in FIG. 9 for a long period of time. There's a problem.

The present invention provides a hinge that facilitates assembly of the tongue piece and the fixed side slat, and that also maintains the positional relationship between the door and the entrance over a long period of time.

(Means for Solving the Problems) Means according to the present invention for solving the above-mentioned problems is, in a hinge in which a fixed side blade plate and a door side blade plate can be separated via a tongue piece, the fixed side blade Two shaft cylinders with female threads cut on the plate are spaced vertically and their shaft centers are aligned,
A tongue piece is provided at one end with a support cylinder having a height lower than the separation height of the shaft cylinders, and the support cylinder of the tongue piece is positioned between the upper and lower shaft cylinders to align the axes of the upper and lower shafts. A shaft is inserted into the support tube of the tube and the tongue piece, and an adjustment screw having a recessed hole formed at one end into which the tip of the shaft fits is screwed from the outer end of the shaft tube, and both ends of the shaft are fitted into the recessed hole. The shaft is crimped and supported, and when the shaft is crimped and supported, the distance between the end faces of the adjustment screws is slightly larger than the height of the support cylinder of the tongue piece.

(Function) With this structure, the tongue piece and the fixed side blade plate can be assembled by positioning the support tube of the tongue piece between the two shaft tubes, inserting the shaft, and tightening the adjustment screw on the shaft tube. This is done by screwing together from the outer end.

Then, by fitting into the recessed hole of the adjusting screw and crimply supporting both ends of the shaft, the shaft is not integrated with the support tube of the tongue piece, so it does not rotate when the door is opened or closed, and is crimply supported by the adjusting screw. The condition is maintained.

In addition, in this crimp-supported state, the gap between the end faces of the adjustment screw is made slightly larger than the height of the support tube of the tongue piece, so even if both ends of the shaft are strongly tightened with the adjustment screw,
The support tube cannot be tightened.

As a result, the tongue piece rotates lightly when the door is opened and closed, and the adjusting screw does not loosen, and the shaft maintains its state for a long period of time due to the strong tightening force of the adjusting screw.

(Example) An embodiment of the present invention will be described in detail below.

In FIGS. 1 and 2, two shaft cylinders 20 having female threads 19 cut on their inner surfaces are integrally provided on the fixed side blade plate 18 with their axes aligned and spaced apart from each other in the vertical direction. 21 is the axis, 2
2 is an adjustment screw screwed into the female thread 19 of the shaft cylinder 20;
This adjustment screw 22 has a recessed hole 2 into which the shaft 21 is fitted.
3 and a hexagonal hole 24 are formed.

Reference numeral 25 is a cap that is screwed onto the female thread 19 of the shaft cylinder 20, and a tool is inserted from the outside into the hexagonal hole 24 of the adjustment screw 22.
A through hole 26 is formed so that the adjusting screw 22 can be rotated. Reference numeral 27 denotes a tongue piece, and a support tube 28 is integrally provided at one end of the tongue piece, and the inner diameter of this support tube is large enough to allow the shaft 21 to be inserted therethrough. The height H of this support cylinder 28 is
As shown in FIG. 1, when both ends of the shaft 21 are fitted into the recessed holes 26 of the adjustment screw 22 and are held under pressure by the tightening force of the adjustment screw 22, the distance between the end faces of the adjustment screw 22 is 1.
It is slightly lower than that. In this way, the height H1 of the support cylinder 28, the length of the shaft 21, and the depth of the recessed hole of the adjusting screw 22 are determined. The tongue piece 28 is provided with operation holes 29 on both sides and a center operation hole 30.

31 is a collar in which a slit 32 is formed.

Reference numeral 33 denotes a door-side wing plate, and protrusions 3435 are formed on both sides. 36 is a tongue insertion hole that opens on the protrusion 35 side. 37 is an operation hole for the side screw 39, 38 is an operation hole for the center screw 40, and when the tongue piece 27 is inserted into the tongue piece insertion hole 36, both side operation holes 29 and the center operation hole 30 made in the tongue piece 27 are inserted. The center of the hole is aligned with the center of the hole.

A more detailed explanation of this door side slat 33 is as follows.
In FIGS. 3 to 5, the protrusions 34.35 and base material holes 41 provided on both sides of the door-side slat 33 are fixed even when the door-side slat 33 is turned upside down. The holes 41 are provided at rotationally symmetrical positions so that they overlap at the same position. The radius W between the end faces of the protrusions 34 and 35 is approximately equal to the thickness T of the door. Figures 4 and 5
As shown in the figure, a protrusion 42 is provided on the back side of the door side blade plate 33.
This protrusion 42 is provided with a screw hole 43 into which the side screw 39 shown in FIG. 2 is screwed and a screw hole 44 into which the central screw 40 is screwed. Further, as shown in FIGS. 6 and 7, the tongue insertion hole 36 is a hole with one side inclined.

The operation of this embodiment configured in this way will be described next.

First, the assembly of the tongue piece 27 and the fixed side blade plate 1B will be explained using FIG.
Align the centers of the support tubes 28 and 28, and screw the zero-order adjusting screw 22 through which the shaft 21 is inserted from the outer end of the shaft tube 20.
Both ends of the shaft 21 are fitted into the recessed holes 23 and tightened, and both ends of the shaft 21 are firmly crimped and supported. Then, attach the cap 25 to the barrel 20.
to screw into. As a result, the tongue piece 27 is attached to the fixed side blade plate 18
be assembled into. Then, insert the tongue piece 27 into the tongue piece insertion hole 36, and screw the side screws 39 from the front side of the door side slat 33 into the screw holes 43 and the center screw 40 from the back side, respectively, and screw the tongue piece 27 and The door side slats 33 are combined.

In FIG. 1, the shaft 21 is tightened firmly by tightening the adjusting screw 22.
Even if both ends of the adjustment screw 22 are strongly crimped, the gap JLa between the end faces of the adjustment screw 22 is slightly larger than the height H of the support cylinder 28.
The support cylinder 28 is not tightened by tightening the adjusting screw 22, so that the tongue piece 27 and the end face of the adjusting screw 22 come into light contact, and the tongue piece rotates around the shaft 21 with a light force. Further, the tightening force of the adjusting screw 22 is maintained by the tightening force of the shaft 21.

In this way, even if the tongue piece 27 rotates together with the door, the adjustment screw 22 will not loosen.

Next, C1 shown in FIG. To adjust C2, use cap 25
Insert the tool through the through hole 26, attach it to the hexagonal hole 24 of the adjusting screw 22, and turn the adjusting screw 22 to move it up and down. As a result, the tongue piece 27 moves up and down between the shaft tubes 20 along the slit 32 of the collar 31, and the door side blade plate 33 also moves up and down, so that the C-U and C2 gaps of the door I are adjusted.

Then, after completing the adjustment, tighten the adjustment screw 22 strongly. Next, for example, as shown in FIG. If it is installed like this, the gap C3 will need to be adjusted.

In this case, open the door l'' and adjust as follows. In Fig. 8, from the front side, using the tool 46, insert the tool 46 through the side screws 39 and the operation hole 38, and then tighten the center screw 40. , and move the tongue piece 27 within the tongue piece insertion hole 36 (see FIG. 17).

Next, as shown in Fig. 11, the thickness T of the door l and the protrusion @
The end faces W of 34.35 are approximately equal, and the protruding portion 34.3
5 and the mounting hole 41 are rotationally symmetrical, so the door 1
The mounting seat holes drilled in the
0 is inserted. When the door-side wing plate 33 is fitted, the end face of the protruding portion 34 is exposed as one with the surface of the door 1, and the appearance thereof is not impaired. and,
Even if the top and bottom of the door side slat 33 are reversed, the door side slat 3
3 fits into the mounting seat surface 481 2 , the projections 34 and 35 fit into the projection fitting g850, and the projection 42 (FIG. 4) fits into the mounting seat surface 49.

Reversing the top and bottom of the door-side wing plate 33 in this way means that the door 1 opens outward when the direction of arrow A is set as the direction of entry, as shown in FIG. 13, for example. Therefore, on the outside of the door 1, a mounting seat hole is drilled in the door 1, leaving an inner portion of thickness t.

However, as shown in FIG. 14, when the inward-opening door 1 is delivered to the site, there is an inconvenience that it cannot be installed because the mounting seat of the door 1 is dug in the opposite direction.

Even in such a case, as shown in FIG. 11, it can be handled by providing a mounting seat hole regardless of whether it opens inward or outward, and by reversing the top and bottom of the door-side wing plate 33. That is,
As shown in FIG. 12, the tongue piece 27 of the fixed side blade plate 18 has the protrusion 35 with the tongue piece insertion hole 36 fixed to the pillar 46.
The top and bottom of the door side slat 33 can be selected according to the insertion direction, and the door side slat 33 can be attached to the mounting seat hole drilled in the door l.

(Effects of the Invention) As detailed above, according to the present invention, the centers of the shaft tube provided on the fixed side blade plate and the support tube provided on the tongue piece are aligned, the shaft is inserted, and the shaft is adjusted with the adjusting screw. Since both ends are supported in pressure contact, the tongue piece and the stationary wing plate can be easily assembled.

In addition, with both ends of the shaft crimped and supported by the adjustment screw, the gap between the end faces of the adjustment screw is made slightly larger than the height of the support tube of the tongue piece, so that the tongue piece can be rotated slightly and the adjustment screw can be loosened. Even if you open and close the door for a long time,
Avoid creating crevices in the gap between the door and the entrance.
