Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a door hinge having a function of adjusting the vertical and horizontal positions of a door relative to a door frame.

[Conventional technology]

This type of door hinge has a hinge disclosed in Japanese Utility Model Laid-Open No. Sho 62-16671. As shown in FIG. 11, the hinge is provided with an adjusting screw 41 on the upper and lower ends of the hinge shaft 40, and the adjusting screw 41 is used to adjust the hinge shaft 40.
The vertical position adjustment of the door 42 with respect to the door frame 43 (hereinafter simply referred to as vertical adjustment) is performed by moving the.

Further, the hinge plate 44 on the side of the door frame 43 is attached to the door frame 43 with a screw via the adjustment base 45, and the hinge plate 44 is received and supported by the base 45 by the gap adjusting screw 46 screwed into the adjustment base 45. By operating 46 to change the gap e, the lateral position adjustment of the door 42 with respect to the door frame 43 (hereinafter simply referred to as lateral adjustment) is performed. The clearance adjusting screw 46 is screwed in from the outer surface of the hinge plate 44, and a flange 47 that supports the hinge plate 44 is formed to project inside the operating head.

[Problems to be solved by the device]

Such a conventional hinge has a problem in that the amount of the clearance e between the hinge plate 44 and the adjustment base 45 is changed to perform the lateral adjustment.

That is, this type of hinge is at least two above and below the door 42.
Since it is installed at the location, it is necessary to match the adjustment amounts of the upper and lower hinges. However, it is difficult to accurately match the screwing amounts of the upper and lower clearance adjusting screws 46, and in many cases, the door frame 43
On the other hand, the door 42 tends to tilt left and right.

In particular, when the gap adjusting screws 46 for supporting the upper and lower hinge plates 44 are provided at a plurality of upper and lower (or left and right) positions, for example, as shown in FIGS. It tends to have a non-parallel posture. Such improper adjustment means that an unreasonable force acts on the hinge shaft 40 and the bearing cylinder 48, causing abnormal wear on the sliding surface and generating an unpleasant squeaking noise when the door is opened and closed.

Further, in the conventional hinge, the vertical adjustment of the door 42 is performed by directly operating the hinge shaft 40 up and down. For this reason, the adjustment screw 41 cannot be operated unless the door 42 is widely opened and the gap dimension G between the end wall of the door 42 on the suspension side and the door frame 43 is set to a certain value or more. The 41 had to be operated from directly above or below, and there was a problem in that it was difficult to perform adjustment work especially near the floor or ceiling wall.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to obtain a door hinge capable of surely preventing misalignment such as upper and lower hinge plates tilting non-parallel.

Another object of the present invention is to provide a door hinge that allows easy adjustment work of the door with respect to the door frame in the vertical and horizontal directions.

[Means for solving the problem]

The present invention has an adjusting base 4 attached to the door frame 2 as shown in FIGS.
One of the hinge plates 6 is fixed by screws 14 between the hinge plate 6 and the adjusting base 4, and vertical adjusting means for adjusting the vertical position of the door 1 and the horizontal position of the door 1 are provided. It is premised on a door hinge provided with a lateral adjusting means for adjusting.

Then, the vertical adjusting means includes a pair of vertical adjusting screws 15 screwed into the screw boss 17 of the adjusting base 4 in a vertically opposed posture,
A pair of upper and lower screw receiving wall surfaces 16 provided on the hinge plate 6 side corresponding to both screws 15 are included, and the vertical interval between the screw bosses 17 is at least the adjustment stroke from the vertical interval between the screw receiving wall surfaces 16. Larger setting, both vertical adjustment screws 15, the central axis of the screw is tilted so that the operating portion side is farther from the adjustment base 4 than the screw tip, and the horizontal adjustment means is the vertical axis provided on the adjustment base 4. The surrounding partial arcuate support wall 19, the joint wall 20 on the side of the hinge plate 6 that is circumscribed to the support wall 19 and tilts in the plate thickness direction, and the circumscribing posture of the support wall 19 and the joint wall 20 are defined. It is required to include the lateral adjustment screw 21.

As a more specific structure of the lateral adjustment means, the support wall 19 is formed as a concave arc wall which is concave toward the inner surface side of the adjustment base 4, and the joint wall 20 is formed.
Can be formed as a partial arc wall along the support wall 19. Further, the support wall 19 can be formed as a projecting arc wall projecting toward the outer surface of the adjustment base 4, and the joining wall 20 can be formed as a flat wall or a partial arc wall along the projecting arc wall. In the case where the projecting arc wall is used as the joint surface, the joint wall 20 may be fixed to the adjustment base 4 by a plurality of screws 14 that also serve as the lateral adjustment screws 21.

[Action]

The vertical adjustment means and the horizontal adjustment means are collectively disposed between the hinge plate 6 and the adjustment base 4 on one side. The door 1 is simply opened to open the outer surface of the hinge plate 6. This is so that adjustment can be performed collectively.

The screw central axis of the vertical adjusting screw 15 is inclined because the screw 15 is inclined toward the operator facing the hinge plate 6 and the adjusting operation is performed in a comfortable posture on site. Because it can be done.

The lateral adjusting means uses the support wall 19 formed of a partial arc wall around the vertical axis and the joining wall 20 circumscribing the supporting wall 19 and tilting in the plate thickness direction, because the joining wall 20 is the supporting wall. This is because the door 1 is laterally adjusted by inclining in a line contact shape or a surface contact shape along an arcuate surface to prevent at least the upper and lower hinge plates 6 from being in a non-parallel posture.

Of the tilting displacement of the joint wall 20, as shown in FIG. 6, only the lateral movement component h works effectively for lateral adjustment of the door 1. This leads to avoiding a large difference in the adjustment amount of the upper and lower hinge plates 6 even if there is a slight difference in the operation amount of the lateral adjustment screw 21.

[Effect of device]

According to the present invention, the adjusting operation of the vertical adjusting means and the horizontal adjusting means can be collectively performed on the outer surface side of the hinge plate 6 mounted on the adjusting base 4. Further, the central axis of the vertical adjusting screw 15 is tilted toward the operator who faces the hinge plate 6 so that the adjusting operation can be performed in a comfortable posture. Therefore, the position adjustment work of the door 1 as a whole can be performed easily and quickly.

Since the joint wall 20 provided on the hinge plate 6 tilts along the supporting wall 19 in the shape of a partial arc around the vertical axis while maintaining a line or surface contact state, lateral adjustment is performed, so that at least each hinge plate 6 Can be prevented from becoming a non-vertical posture. Moreover, the lateral movement component h included in the tilt displacement
Since only one is effective for the lateral adjustment of the door 1, it is possible to avoid a large difference in the lateral movement amount of the upper and lower hinge plates 6 even if the operation amount of the lateral adjustment screw 21 is different in the vertical direction. This eliminates misalignment such that the upper and lower hinge plates 6 are in non-parallel postures. In addition, it is possible to eliminate the action of unreasonable force on the sliding surface of the hinge shaft 7 and the bearing walls 8 and 9 thereof, and it is possible to reliably prevent abnormal wear of the sliding surface and squeaking noise when the door is opened and closed.

The vertical adjustment screw 15 can be screwed into each screw boss 17 from the outside in the vertical direction. At this time, as shown in FIG. 2 and FIG. 5, the adjusting screw 15 has its central axis inclined so that its operating portion is farther from the adjusting base 4 than the screw tip.

The vertical interval between the two screw bosses 17 and 17 is set to be larger than the vertical interval between the pair of screw receiving wall surfaces 16 and 16.
・ Secure a vertical adjustment stroke between 17 points.

A lateral adjusting means is provided for performing lateral position adjustment, that is, lateral adjustment of the door 1.

This lateral adjustment means is a support wall of a partially arcuate shape that is formed in the adjustment base 4 between the pair of screw bosses 17 and 17.
It is composed of a support wall 19, a joint wall 20 that is in contact with the support wall 19 and tilts in the thickness direction of the hinge plate 6, and has a lateral adjustment screw 21 that defines the circumscribing posture of both walls 19 and 20. This junction wall 20
Are integrally connected to the hinge plate 6, and the upper and lower end surfaces of the joint wall 20 are the screw receiving wall surfaces 16 and 16.

In FIG. 6, the support wall 19 and the joint wall 20 have arcuate wall surfaces with the same radius around the vertical axis, and the joint wall 20 moves along the support wall 19 while maintaining the surface contact state,
The hinge shaft 7 can be displaced around the virtual center P of the circular arc wall surface between a solid line state and an imaginary line state. Of this displacement amount, only the lateral movement component h is effective for lateral adjustment of the door 1.

In FIG. 2 and FIG. 3, an operating head 22 having a larger diameter than the screw shaft portion and a flange 23 are formed adjacent to each other at one end of the lateral adjusting screw 21. A mating shaft portion 24 is provided. Further, a screw receiving claw 25 is formed by cutting and raising in the upper and lower central portions of the base end of the joining wall 20, and a groove 26 into which the engaging shaft portion 24 is fitted is formed in a notch shape in the center thereof. There is.

The lateral adjusting screw 21 is attached to the hinge plate 6 in a state where the engaging shaft portion 24 is engaged with the groove 26, and is screwed into the screw block 12 through the screw insertion hole 27 provided in the adjusting base 4. By adjusting the screwing amount of the lateral adjustment screw 21, the hinge plate 6 moves along the support wall 19 as described above, and the circumscribing posture of the support wall 19 and the joint wall 20 is defined. .

The hinge plate 6 and the adjustment base 4 are sandwiched and held by the inner and outer screw blocks 12 and the seat plate 13. The hinge plate 6 moves up and down in the state of being sandwiched and held, and tilts along the support wall 19. For that, the screw block 12
Was supported by the adjustment base so that it would accompany the hinge plate 6 only above and below.

In detail, sliding contact portions 29 having a convex cross section are provided above and below the screw block 12, and the sliding contact portions 29 are fitted into a guide groove 30 provided in a penetrating shape at the center of the support wall 19 to guide and support only vertical movement. . A screw boss 31 for the screw 14 is projectingly provided on each sliding portion 29.
The screw boss 31 protrudes to the outer surface of the support wall 19 through the guide groove 30, and is an escape groove provided along the curved surface of the joint wall 20.
32 is engaged. Screw boss when the joint wall 20 tilts
In order to avoid interference with 31, the escape groove 32 is formed in an elliptical shape along the arc surface.

On one side of the center of the screw block 12, a female screw portion 33 for the lateral adjustment screw 21 is provided so as to project, and this female screw portion 33 is also connected to the joint wall 20.
To go up and down. Therefore, the screw insertion hole 27 is formed in an oval shape that is long in the vertical direction.

Seat plate 13 fastened with screws 14 to screw block 12
Cannot follow the tilting of the joint wall 20. Therefore, the mounting surface 34 of the seat plate 13 to the joint wall 20 is formed as a projected arc surface and joined to the joint wall 20 so as to be relatively movable. Seat plate
A notch 35 that avoids the screw receiving claw 25 is formed on one side edge of the side wall 13.

The operating head 22 of the lateral adjustment screw 21 projects from the outer surface of the hinge plate 6 as shown in FIG. This operation head
In order to prevent the hinge plate 5 on the door 1 side from abutting and interfering with the door 22, an escape hole 36 is provided in the hinge plate 5 in a penetrating manner.

When performing vertical adjustment now, loosen each screw 14 and
Float 13 from the outer surface of the joint wall 20 to release the constraint with the joint wall 20. In this state, for example, if the upper vertical adjusting screw 15 is loosened and the lower vertical adjusting screw 15 is screwed in, the door 1 is adjusted and moved upward in accordance with the screwing amount. Of course, the same adjustment is made for each of the upper and lower door hinges. After the adjustment is completed, the screw 14 is screwed in and the joint wall 20 is fixed by the seat plate 13.

Even when adjusting the sideways, first loosen the screws 14 and lift the seat plate 13,
In this state, the horizontal adjustment screw 21 is operated. For example, when the latching amount of the latch provided on the door 1 is unexpected, the lateral adjustment screw 21 is loosened and the joint wall 20 is tilted to the position shown by the imaginary line in FIG. On the contrary, when the swinging tip of the door 1 interferes with the door frame 2, the lateral adjusting screw 21 is screwed in and the joint wall 20 is tilted in the opposite direction to the above by the seat plate 13. The horizontal adjustment is performed in this manner, and finally, the screw 14 is screwed in to fix the joint wall 20.

According to such a door hinge, the vertical and horizontal position adjustments can be collectively and quickly performed only on the hinge plate 6 side simply by opening the door 1 and opening the outer surface of the hinge plate 6. Moreover, since the screw central axis of the vertical adjustment screw 15 is inclined toward the operator facing the hinge plate 6, the vertical adjustment screw 15 near the floor surface or the ceiling wall can be easily operated.

The joint wall 20 moves along the support wall 19 at the time of lateral adjustment, and is tilted by being guided by the screw boss 31.
It is pressed by and comes into close contact with the support wall 19. Therefore, the hinge shaft 7 does not incline non-vertically at any tilt position, and at least the upper and lower hinge plates 6 can be prevented from being in a non-parallel posture. Of the tilt displacement of the joint wall 20, only the lateral movement component h contributes to the lateral adjustment of the door 1. Therefore, even if there is a slight difference in the lateral adjustment amount between the upper and lower door hinges, its adverse effect can be ignored. It is possible to avoid the situation where most of the door weight acts on one of the upper and lower door hinges.

[Second Embodiment] FIGS. 7 to 9 show a second embodiment of the present invention in which the lateral adjusting means is modified.

In this case, the support wall 19 is a projecting arc wall around the vertical axis which projects to the outer surface of the adjusting base 4 and is formed in a vertically long rib shape, and the joint wall 20 is formed as a flat end wall. And the lateral adjustment screw
The circumscribing posture of the joint wall 20 with respect to the support wall 19 can be regulated by the four screws 14 which also serve as 21. Further, corresponding to the upper and lower vertical adjusting screws 15, the screw receiving wall surfaces 16 are integrally formed above and below the joint wall 20.

Two screws 14 are arranged on each side of the rib-shaped support wall 19, and the joining wall 20 can be tilted like a seesaw by loosening one upper and lower pair and screwing the other upper and lower pair. The screw block 12 is divided so as to correspond to a pair of upper and lower screws 14. The same members as those in the first embodiment are designated by the same reference numerals and the description thereof is omitted.

In this way, the support wall 19 can be formed as a projecting arc wall. If necessary, the joint wall 20 may be formed as a concave arc wall having the same arc as the support wall 19.

[Third Embodiment] FIG. 10 shows a third embodiment of the present invention in which the lateral adjusting means is further modified. In this case, the support wall 19 having an arcuate shape is formed in a concave shape on the adjustment base 4, and the tip of the hinge plate 6 is rounded to form a joint wall 20. The joint wall 20 is fitted in the support wall 19 so that the hinge plate 6 can be tilted around the arc center of the support wall 19.
