Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hinge for a fitting used for a door of a building or the like, and more particularly to a hinge for a fitting which can adjust the fishing height of the door and evenly distribute the load.

[0002]

2. Description of the Related Art Conventionally, hinges for fittings have been used for doors of buildings and the like. For example, doors requiring airtight shutoff such as soundproof doors, airtight doors, waterproof tideproof doors, electromagnetic wave shutoff doors, and the like. For heavy doors such as gates, repair doors, etc., special fitting hinges are used because the doors need to be adjusted for fishing. Here, an example of a special hinge for fittings having a conventional height adjusting mechanism is shown in FIGS. 5 and 6. The hinge for fittings includes a frame fixing member 80 for fixing to a frame (not shown) fixed to a wall or the like, and a door fixing member 82 for fixing to a door (not shown). The frame fixing member 80 includes a first cylindrical portion 86 having a through hole 84 formed therein and a plurality of screw insertion holes 8.
8 and a first wing 90 formed with the first wing. Door fixing member 8
2 is an axial hole 92 from one end face to the inside of the inside.
And a second wing portion 98 having a plurality of screw insertion holes 96 formed therein. The second cylindrical portion 94 is arranged higher than the first cylindrical portion 86, and the second cylindrical portion 94 is arranged such that the opening side of the hole 92 of the second cylindrical portion 94 faces the first cylindrical portion 86.

A female screw 100 is formed below the through hole 84 of the first cylindrical portion 86, and an adjusting screw 102 having a male screw formed on the surface is screwed to the female screw 100. A vertically movable shaft 104 projects outward from the upper end of the through hole 84, and the projected shaft 104 fits into the hole 92 of the second cylindrical portion 94. This axis 10
The projecting tip of 4 is set so as to always contact the closed end of the hole 92 of the second cylindrical portion 94. By rotating the adjusting screw 102, the length of the shaft 104 protruding from the first cylindrical portion 86 advances and retreats. Thereby, the frame fixing member 80
, The relative position of the door fixing member 82 is displaced, so that the fishing height of the door can be adjusted.

[0004]

In a conventional hinge for fittings having a height adjusting mechanism, a member fixed to a door and a member fixed to a frame are generally separated. For this reason, when the mounting positions of the hinge members fixed to the door and the mounting positions of the hinge members fixed to the frame are shifted, a large load is applied to only one hinge, and the other hinge is applied. Will be loaded with a small load. As a result, if the weight of the door is heavy, the door may be inclined or the frame may be distorted. As shown in FIGS. 5 and 6, the conventional hinge for fittings generally has a first wing portion 90 provided at a position offset from the axial center of the first cylindrical portion 86, and a shaft of the second cylindrical portion 94. The second wing 9 at a position offset from the center
8 are provided. For this reason, when the direction of the frame fixing member 80 and the direction of the door fixing member 82 shown in FIGS. 5 and 6 are opposite to each other, the frame fixing member 80 having the first wing 90 formed in the opposite direction, or the opposite direction. In this case, the door fixing member 82 having the second wing portion 98 must be prepared, which is not only costly but also hinders the progress of work on site.
Further, the conventional hinge for fittings having a height adjusting mechanism is provided with a shaft 10
Since the structure 4 receives the load of the door, the shaft 104 and the first cylindrical portion 86 holding the shaft 104 must be enlarged.
The entire hinge must be large in size compared to the load bearing capacity, resulting in a high cost. In addition, if the gap between the hole 92 or the through hole 84 and the shaft 104 in the fitted state is large,
Since the shaft 104 falls down with respect to the first cylindrical portion 86, it is necessary to increase the fitting accuracy, and there is a disadvantage that the processing cost increases and the product becomes expensive.

Conventionally, a hinge for a fitting for supporting a load of a door is usually mounted near the lowermost portion of the frame in order to reduce the influence of the load deformation of the frame. Was near. For this reason, the position of the adjusting screw 102 for vertically adjusting the shaft 104 is lowered, and when adjusting the height of the door with a driver, not only is the operator forced to squat down, but also a screwdriver for adjustment is required. There is a drawback that the recess of the adjusting screw 102 for fitting a tool such as the above cannot be seen, and the workability is poor due to groping.
Furthermore, since there is no space to the floor, sufficient force cannot be applied to the tools.When adjusting heavy doors, one person inserts a wedge or bar at the bottom of the door, lifts the door, and places a load on the hinges for fittings. In reality, the other person turns the adjusting screw 96 to adjust the height, and the large door requires two workers for installation work.

SUMMARY OF THE INVENTION The present invention has been made in view of the above points, and has a structure capable of uniformly supporting and supporting a load of a door, supporting a small and large weight, being applicable to both right and left directions, and a work of door installation work. It is an object of the present invention to provide a hinge for fittings capable of improving the property.

The hinge for fittings according to the present invention comprises a frame 1
It has a first fixing member 12 for fixing to zero and a second fixing member 16 for fixing to the door 14. The first fixing member 12 includes a first cylindrical portion 18 having a through hole 17 formed therein,
It comprises two plate portions 22 provided with screw insertion holes 20 formed at both axial ends of the first cylindrical portion 18. A screw 24 is inserted into the screw insertion hole 20, and the first fixing member 12 is fixed to the frame 10 by the screw 24. On this occasion,
The first fixing member 12 is attached along the longitudinal direction of the frame 10 and does not have a conventional wing. A spring 30 is provided in the through hole 17 of the first cylindrical portion 18 so as to be sandwiched between a bearing part 26 and an adjusting screw 28 having an external thread formed on an outer wall. The bearing part 26
Can move freely inside the first cylindrical portion 18, but the inner wall protruding portion 32 as a stopper protruding inside the first cylindrical portion 18 prevents it from moving outside from that position. Has become. A female screw 33 is formed on the lower inner wall of the through hole 17, and the adjusting screw 28 is screwed into the female screw 33. The spring 30 expands and contracts by moving the adjusting screw 28 through the through hole 17 of the first cylindrical portion 18, and the magnitude of the spring force of the spring 30 can be adjusted by the expansion and contraction. Adjustment screw 2

It is desirable that the lock nut 50 be provided with a through hole of a polygonal diameter hole having a facing dimension larger than the diagonal dimension of the hexagonal hole 48. After the lock nut 50 is screwed into the second cylindrical portion 34, the end of the second cylindrical portion 34 is closed with the cap 52. As described above, the magnitude of the spring force of the spring 30 can be adjusted by expanding and contracting the spring 30 with the adjusting screw 28, but the shaft 44 is advanced and retracted while being screwed into the second cylindrical portion 34. This also allows the spring 30 to expand and contract to adjust the magnitude of the spring force of the spring 30.

[0010] The frame 10 using the hinge for fittings according to the present invention.
When attaching the door 14 to the first fixing member 1
2 is fixed to the frame 10, and a second fixing member 16 separate from the first fixing member 12 is fixed to the door 14. After that, the tip of the shaft 44 protruding outside the second cylindrical portion 34 in the second fixing member 16 is inserted into the through hole 17 of the first cylindrical portion 18 in the first fixing member 12. At this time, it is desirable to provide a dry bearing 54 with a flange at the insertion opening position of the through hole 17 into which the shaft 44 is inserted. When the end of the shaft 44 is inserted into the through hole 17, the ball 46 at the end of the shaft 44 presses the bearing component 26 to compress the spring 30. That is, in the state where the door 14 is attached to the frame 10 using the hinge for fittings according to the present invention, the weight of the door 14 is received by the spring 30,
With spring 30 compressed to some extent, a balance is maintained to support door 14. In addition, the door 14 is
1 and 2, the height adjustment is performed between the first cylindrical portion 18 of the first fixing member 12 and the second cylindrical portion 34 of the second fixing member 16 as shown in FIGS. Is set so that a gap L is formed. With the gap L for height adjustment, the height can be adjusted.

The door 14 is generally supported on the frame 10 by two (or sometimes three or more) hinges for fittings. Here, for example, a conventionally known ordinary hinge having no height adjustment mechanism (one in which a member fixed to the frame 10 and a member fixed to the door 14 are integrated) is used on one side, and the other according to the present invention is used on the other side. Assume that a hinge for fittings is used. In the hinge for fittings according to the present invention, since the spring 30 receives the load shared by the door 14, even if the mounting positions of the two hinges are displaced, the load equally applied to the spring 30 is applied. In the case where the mounting positions of the two hinges are displaced, only the adjustment gap L shown in FIGS. 1 and 2 changes, and the load applied to the spring 30 does not change. As a result, the load of the door 14 applied to the two hinges is always equal, and it is possible to prevent the door 14 from being inclined or the frame 10 from being distorted.

In the hinge for fittings according to the present invention, the spring 3
Since a load is received by 0, an excessive load can be received as compared with a conventional shaft receiving a load. In addition, even if a difference occurs between the position at which the first fixing member 12 is attached to the frame 10 and the position at which the second fixing member 16 is attached to the door 14, the load sharing can be made uniform. Does not need to be set strictly, and the mounting work becomes very easy. In the present invention, the second cylindrical portion 34 of the second fixing member 16 is further provided with a through hole 42 having a female screw 41 formed thereon, and a shaft 44 having a male screw formed on the outer wall is screwed into the through hole 42. Since the shaft 44 is provided, the shaft 44 can be screwed into the through hole 42 of the second cylindrical portion 34 from either opening. As a result, the second fixing member 16 can be turned upside down (indicated by the dashed line in FIG. 2), and the screw insertion hole 36 can be aligned in a desired direction even when the door needs to be changed from side to side. It is possible to prevent delays in work and to improve the efficiency of production. The movement of the position of the spring 30 and the change of the spring force are performed by operating the adjusting mechanism of the spring 30 of either the adjusting screw 28 screwed to the first cylindrical portion 18 or the shaft 44 screwed to the second cylindrical portion 34. It can be carried out. Thus, the height of the door 14 with respect to the frame 10 can be adjusted up and down, and the fishing height of the door 14 with respect to the frame 10 can be adjusted up and down. Furthermore, when the hinge for fittings is attached to the lower part of the frame 10, it may be difficult to operate the adjusting screw 28 screwed to the first cylindrical portion 18 from below the first cylindrical portion 18. By removing the cap 52 on the two cylindrical portions 34 and operating the shaft 44 from above, the spring 30 can be expanded and contracted. As described above, since the advance and retreat of the shaft 44 can be operated using a tool from above, a comfortable working posture can be taken when adjusting the spring 30.
In addition, the space for the tool can be increased, the force can be easily applied, and the adjustment operation can be performed while observing the state of the door 14 as a whole. As a result, the adjustment work conventionally performed by two persons can be performed by one person. Also, the spring 30 only has to share the load in the vertical direction, and the horizontal force and positioning are borne by the first cylindrical portion 18 which does not move at the time of adjustment. And the processing cost can be reduced.

Can be changed.

In the hinge for fittings of the present invention shown in FIG. 4, since the load of the door 14 is received by the spring 62, the load can be equally distributed to a plurality of hinges for fittings. Further, since the load of the door 14 is received by the spring 62, an excessive load can be received as compared with a conventional shaft receiving a load. In the hinge for fittings of the present invention shown in FIG. 4, the second fixing member 60 is provided with a through hole 70 formed by cutting a female screw inside the second cylindrical portion 72, and caps are provided at both openings of the through hole 70. Since the female screw to be screwed with the second fixing member 76 is formed, the direction of the second fixing member 60 can be reversed by turning the second fixing member 60 upside down (the dashed line in FIG. 2). The member 60 can be turned upside down, so that the present invention can be applied to the case where the right and left of the door needs to be changed. In the present invention shown in FIG. 4, since the spring 62 can be moved by adjusting the cap 76 and the shaft 58, the height of the door 14 with respect to the frame 10 can be adjusted up and down. The cap 62 attached to the second cylindrical portion 72 of the second fixing member 60 allows the spring 62
The adjustment operation of the spring force can be performed, so that a comfortable working posture can be obtained by the operation from above. As a result, the adjustment work conventionally performed by two persons can be performed by one person.

In the above description, one of the hinges for supporting the door 14 is used as a normal hinge, and the other hinge is used for the fitting according to the present invention. The hinge for fittings according to the present invention may be used for all hinges. Furthermore, although the hinge for fittings of the present invention has been described as supporting the door, it may be configured to support something other than the door.

[0016]
