DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hinge for rotatably attaching a door to an opening of a building such as a building or furniture.

[0002]

2. Description of the Related Art In general, a hinge of this type includes a fixing member attached to a frame and a connecting member rotatably attached to a door. The hinge is pressed against the fixing member. When the base member is moved from the proximal end to the distal end to a predetermined attachment position, the connecting member is attached to the fixing member. Thus, the door is rotatably attached to the frame.

In the hinge having the above structure, the connecting member is moved to a predetermined mounting position and is mounted on the fixing member. Therefore, when the connecting member moves in a direction opposite to the moving direction during mounting after mounting, the connecting member is fixed. It will come off the member. Therefore, an engaging mechanism is provided between the fixed member and the connecting member, the engaging mechanism being engaged when the connecting member is moved to a predetermined mounting position, whereby the connecting member is moved in a direction opposite to the moving direction. They try to prevent them from moving. This engagement mechanism is configured as follows, for example.

That is, while the contact member is fixed to the fixing member, one end of a lever (displacement member) is rotatably provided to the connecting member. When the lever is rotated, the other end is displaced in the direction in which the connecting member is pressed and in the direction opposite thereto, so that the lever can move closer to and away from the contact member. Moreover, the lever is urged by a spring in a direction in which one end moves closer to the contact member. Further, the contact member and the lever are arranged so that when the connecting member is moved to the mounting position, the connecting member abuts before reaching the mounting position, and after the abutting, the connecting member is further moved to the mounting position side. When moved, the abutment member rotates the lever away from the abutment member against the biasing force of the spring. When the connecting member reaches the mounting position, the lever is rotated by the biasing force of the spring so as to approach the contact member, and the contact member and the lever are engaged.
This prevents the connecting member from moving in the direction opposite to the moving direction (see Japanese Patent Publication No. 5-870).

[0005]

In the above-mentioned conventional hinge, the lever is rotated by the contact member against the urging force of the spring when the connecting member is moved.
When attaching the connecting member to the fixed member, it is necessary to not only move the connecting member but also to press the connecting member against the fixing member against the urging force of the spring. Such an installation work is very difficult because the work must be performed with the door lifted, and not only requires a great deal of labor from the operator. There has been a problem that the work efficiency is reduced.

The contact member provided to be fixed to one of the fixed member and the connecting member, and the other is provided to be displaceable in the pressing direction and the opposite direction to the pressing direction, and the pressing direction by the elastic member. A displacement member urged in the opposite direction, and when the connecting member is moved toward the mounting position, the contact member abuts on the displacement member, and the contact member is pressed against the urging force of the elastic member. When the connecting member reaches almost the mounting position, the connecting member is displaced by the elastic member and engages with the contact member. In a hinge provided with an engagement mechanism for preventing movement from an attachment position to a proximal end side, between the fixing member and the connecting member, the contact member presses the displacement member against the urging force of the elastic member. And a movement preventing mechanism for preventing the connecting member from moving in a direction opposite to the pressing direction during the displacement of the connecting member. In this case, the contact member may be provided on the connecting member, and the displacement member may be provided on the fixed member. The movement preventing mechanism may be provided between the contact member and the fixing member. The fixing member and the connecting member each have opposed plate portions facing each other in the pressing direction of the connecting member, and the opposed plate portion of the fixing member has an insertion hole penetrating therethrough. The contact member is provided on an opposing plate portion of the connection member facing the hole, and the contact member penetrates the insertion hole when the connection member is pressed against the fixing member, and the connection member When the contact member is displaced against the urging force of the elastic member when the contact member is moved to the mounting position side, the contact member faces the pressing direction of the opposing plate portion of the fixed member. An engagement piece that engages with the surface and prevents the contact member from moving in the direction opposite to the pressing direction is formed,
It is preferable that the movement preventing mechanism is constituted by the engagement piece and a surface of the fixing member which is engaged with the engagement piece and faces the pressing direction of the facing plate.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A preferred embodiment of the present invention will be described below with reference to FIGS. 1 to 4
1 shows an embodiment of the hinge according to the present invention, and the hinge 1 shown in these figures comprises a fixing member 2 and a connecting member 5.
Are the main components.

The fixing member 2 has a mounting plate 3 and a guide plate 4. Mounting plate 3, which form a flat, by screws inserted through the screw insertion hole 3a (not shown) is fixed to the opening B ₁ near the inner surface B ₂ of the precursor B of the wardrobe, etc. . On the other hand, the guide plate 4 is forms a substantially U-shaped cross section, and a top plate portion (facing plate portion) 4a extending along the inner surface B ₂ to the back side from the opening B ₁ side of building frame B, the top plate side plate portion 4b projecting from both sides of the parts 4a on the inner surface B ₂ side, and a 4c. Then, the guide plate 4 has a base end at a frame B
Is positioned on the side of the opening B ₁ , and the distal end thereof is positioned on the inner side of the frame B, and is attached to the mounting plate 3 by bolts 6 that pass through the top plate 4 a and screw into the mounting plate 3. Fixed. In this case, the guide plate 4 is positioned by the projection 4d being fitted into the concave portion 3b of the mounting plate 3 and the engaging groove 4e being fitted into the front end of the mounting plate 3 (the end on the back side of the frame B). Have been.

The connecting member 5 has a U-shaped cross section similarly to the guide plate 3, and has a top plate (opposing plate) 5a and side plates 5b and 5c. And the connecting member 5
Has a guide plate 4 fitted therein, and is connected and fixed to the guide plate 4 as described later. In addition, at the base end (the left end in FIG. 1) of the connecting member 5,
A door (both not shown) is rotatably connected via a rotation connection mechanism and a holder. Therefore, when the connecting member 5 is attached to the fixing member 2, the door is rotatably supported by the frame B. Note that the same rotary coupling mechanism and holder as those known in the art are used, and they are not directly related to the present invention. Therefore, description of those details is omitted.

Next, the structure for fixing the connecting member 5 to the fixing member 2 will be described. The connecting member 5 is inserted into the guide plate 4 in a direction perpendicular to the side plates 5b and 5c (the vertical direction of the frame B). ) Is restricted.

An adjusting screw 7 is screwed into the top plate 4a of the guide plate 4. The adjusting screw 7 has a lower large diameter portion (large diameter portion) 7a, an upper large diameter portion (large diameter portion) 7b, and a small diameter portion 7c formed therebetween. These outer diameters are largest at the lower large diameter portion 7a, and are smaller in the order of the upper large diameter portion 7b and the small diameter portion 7c. On the other hand, a large hole 5d that penetrates the top plate portion 5a of the connecting member 5 and a small hole 5e extending from the large hole 5d toward the base end of the top plate portion 5a are formed in the center of the top plate portion 5a. ing. The large hole 5d is formed such that the upper large diameter portion 7b can be inserted, but the lower large diameter portion 7b cannot be inserted. On the other hand, the small hole 5e is formed to have almost the same size as the small diameter portion 7c. Therefore, when the large hole 5d of the connecting member 5 is opposed to the adjusting screw 7 and the connecting member 5 is moved in a direction indicated by an arrow in FIG. The upper large diameter portion 7b of 7 passes through the large hole 5d, and the small diameter portion 7c enters the large hole 5d. When the connecting member 5 is moved to the tip side in this state, the small diameter portion 7c is
And the top plate portion 5a of the connecting member 5 is
a, 7b. This restricts the movement of the connecting member 5 in a direction orthogonal to the top panel 5a (the left-right direction of the frame B).

Further, the movement of the connecting member 5 in the longitudinal direction (the front-rear direction of the frame B) is restricted by the engagement mechanism 8 described below. That is, the top plate portion 4a of the guide plate 4 has a long hole (insertion hole) 4f extending from the center of the top plate portion 4a toward the front end, and a rectangular hole 4g communicating with the front end of the long hole 4f. Are formed. The width of the rectangular hole 4g (the dimension in the direction orthogonal to the side plates 4b and 4c) is smaller than the width of the long hole 4f.

A contact member 9 is fixed to the top plate portion 5a of the connecting member 5 by a bolt 10 at a position facing the long hole 4f. The contact member 9 includes a base 9 a fixed to the top plate 5 a by bolts 10, a connecting portion 9 b extending from the center of the front end of the base 9 a toward the guide plate 4, and a connecting portion 9 b or the top plate member 5 a. And an engagement piece 9c extending to the distal end side. The width of the base 9a (the dimension in the direction orthogonal to the side plates 5b and 5c) is wider than the width of the long hole 4f. The width of the connecting portion 9b is smaller than the width of the rectangular hole 4g as well as narrower than the elongated hole 4f. The width of the engagement piece 9c is smaller than the elongated hole 4f but wider than the rectangular hole 4g. The length of the connecting portion 9b (the base 9a
Of the top plate 4a) is substantially the same as the thickness of the top plate 4a. Therefore, FIG.
The distance between the base 9a and the engagement piece 9c in the direction of the arrow in (A) is substantially the same as the thickness of the top plate 4a.

As is clear from the above dimensional relationship, the engaging piece 9c of the contact member 9 can be inserted into the elongated hole 4f.
When the base 9a is inserted into the long hole 4f until it abuts on the top plate 4a, it passes through the long hole 4f. Engagement piece 9
When the connecting member 5 is moved from the proximal end to the distal end in a state where c has passed through the elongated hole 4f, the connecting portion 9b enters the rectangular hole 4g. At this time, since the width of the engaging portion 9c is wider than the width of the rectangular hole 4g, both sides of the engaging portion 9c are almost in contact with the surface 4h of the top plate portion 4a facing the skeleton B side. This prevents the contact member 9 from moving in the direction opposite to the direction of the arrow in FIG. 1A (the direction opposite to the direction in which the connecting member 5 is pressed against the fixing member 2), and thus the connecting member 5 in the same direction. Movement is prevented. From this, it is apparent that the engagement piece 9c and the surface 4h
A movement preventing mechanism for preventing the connecting member 5 from moving in the direction opposite to the pressing direction is configured.

When the adjusting screw 7 is opposed to the large hole 5d, the abutting member 9 is formed so that the engagement piece 9c is in the elongated hole 4f.
Are arranged so as to be able to be inserted. Therefore, the engagement piece 9c can be inserted into the elongated hole 4f at the same time as the adjustment screw 7 is inserted into the large hole 5d. The position of the contact member 9 can be adjusted in the longitudinal direction of the long hole 4f by loosening the bolt 10.

Further, the side plate portion 4 on the distal end side of the guide plate 4 is provided.
A support shaft 11 is provided between b and 4c. One end of a lever (displacement member) 12 is rotatably supported by the support shaft 11. The lever 12 rotates forward and backward around one end, so that the other end is displaced in the direction of the arrow in FIG. 1 (the direction in which the connecting member 5 is pressed) and in the opposite direction. Moreover, the lever 12 is rotationally urged by a spring 13 so that an intermediate portion thereof abuts against the surface 4h of the top plate portion 4a, and the other end of the lever 12 pushes the lever 12 against the urging force of the spring 13. An operation section 12a for turning the camera is provided.

At the tip of the engaging piece 9c and the intermediate portion of the lever 12 opposed thereto, inclined surfaces 9d and 12b are formed, respectively. As shown in FIG. 1 (B), the inclined surfaces 9d and 12b are arranged such that when the connecting member 5 is moved to the distal end side, the engaging piece 9c and the surface 4h abut each other after engaging. When the connecting member 5 is further moved toward the distal end in the abutted state, the inclined surface 12b is pushed by the inclined surface 9d, and the lever 12 is rotated against the urging force of the spring 13. When the connecting member 5 moves until just before the connecting portion 9b abuts on the side surface 4i on the distal end side of the rectangular hole 4g, the inclined surface 9d is turned into the inclined surface 12d.
Get over b. Then, as shown in FIG. 1C, the lever 12 is returned and rotated by the urging force of the spring 13, and the movement preventing portion 12c is connected to the connecting portion 9b of the contact member 9.
It hits the intersection 9e with the engagement piece 9c . Then, the movement preventing portion 12c causes the crossing portion 9e by the urging force of the spring 13.
Is pushed toward the distal end side of the connecting member 5, and the connecting portion 9b is abutted against the side surface 4i on the distal end side of the rectangular hole 4g. This restricts not only the movement of the connecting member 5 from the proximal end to the distal end, but also the movement of the connecting member 5 from the distal end to the proximal end. Note that the position of the connecting member 5 when the connecting portion 9b abuts on the side surface 4i on the distal end side of the rectangular hole 4g is the mounting position.

In the hinge 1 having the above structure, when the connecting member 5 is connected to the fixing member 2, the large hole 5d of the connecting member 5 is used.
And the contact member 9 is opposed to the elongated hole 4f. Then, while maintaining this state, the connecting member 5 is moved in the direction of the arrow in FIG. 1 until the contact member 9 abuts on the top plate portion 4a of the guide plate 4, and the guide member 4 is inserted into the connecting member 5. . Then, the small diameter portion 7c of the adjusting screw 7 enters the large hole 5d, and the engagement piece 9c of the contact member 9 passes through the long hole 4f. Next, the contact member 9
The connecting member 5 is moved to the distal end side while maintaining the state in which it abuts on the top plate portion 4a. Then, the small diameter portion 7c of the adjustment screw 7 enters the small hole 5e, and the contact member 9
9d abuts against the inclined surface 12b of the lever 12. Here, the contact between the inclined surfaces 9d and 12b and the entry of the small-diameter portion 7c into the small hole 5e may be simultaneous or may be preceded by one.
It is desirable that the small diameter portion 7c enters the small hole 5e before the 12b abuts.

When the connecting member 5 is further moved to the distal end side after the inclined surfaces 9d and 12b abut, the inclined surface 9d pushes down the inclined surface 12b against the urging force of the spring 13 with the movement. 12 is rotated away from the contact member 9. At this time, the contact member 9 receives a force in the direction opposite to the direction of the arrow in FIG. 1A by the spring 13, and thus the connecting member 5 receives a force in the same direction. However, the force is supported by the engagement portion 9c abutting on the surface 4h of the top plate portion 4a of the guide member 4. Therefore, the connecting member 5
Does not need to push the connecting member 5 in the direction of the arrow against the urging force of the spring 13, and may simply move the connecting member 5 toward the distal end. Therefore, the connecting member 5 can be easily moved to the distal end side.

The connecting member 5 is further moved so that the inclined surface 9d
Is over the inclined surface 12b, the lever 12
With the urging force of (2), the contact member 9 rotates so as to approach the contact member 9, and the movement preventing portion 12c abuts on the intersection 9e of the contact member 9. Then, the intersecting portion 9e is pushed toward the distal end side of the connecting member 5, and the connecting portion 9b is pressed against the side surface 4i on the distal end side of the rectangular hole 4g. Therefore, the connection member 5 is not only prevented from moving in the direction from the base end side to the distal end side by the side surface 4i, but also moved in the direction from the distal end side to the base end side by the urging force of the spring 13. Will be blocked.

As described above, the connecting member 5 is prevented from moving in the vertical direction of the frame B by the guide plate portion 4 entering the inside thereof, and is prevented from moving in the horizontal direction by the adjusting screw 7. As a result, the frame B is prevented from moving in the front-rear direction by the engagement mechanism 8, so that the frame B is fixedly connected to the fixing member 2.

To remove the connecting member 5 from the fixing member 2, the operating portion 12a of the lever 12 is pushed down, and the lever 1
2 is separated from the contact member 9. Thereafter, the connecting member 5 is moved to the base end side. When the adjusting screw 7 enters the large hole 5d and the engaging piece 9c is opposed to the long hole 4f, the connecting member 5 is moved in a direction opposite to the direction of the arrow in FIG. Good.

By the way, as described above, the door is
After installation, it may be necessary to adjust the cover thickness of the door. Such adjustment of the cover thickness is performed by adjusting the screwing amount of the adjusting screw 7 as shown in FIG. Here, when the screwing amount of the adjusting screw 7 is increased or decreased, the adjusting screw 7 moves linearly in the axial direction, whereas the connecting member 5 rotates about its distal end side as shown by an arrow in FIG. I do. For this reason, if the upper and lower large diameter portions 7a and 7b of the adjusting screw 7 are flat on the surfaces 7d and 7e facing the top plate 5a, the top plate 5
a inclines with respect to the opposing surfaces 7d and 7e, and both interfere with each other. As a result, an excessive force may act on the adjusting screw 7 and the top plate 5a, and the screwing amount of the adjusting screw 7 may not be adjusted smoothly.

In this regard, in this hinge 1, the upper and lower large-diameter portions 7a, 7b are provided with opposing surfaces 7d, 7e facing the top plate portion 5a.
Since the tapered surface is inclined so as to move away from the top plate portion 5a as going outward from the small diameter portion 7c, the opposed surfaces 7d and 7e and the top plate portion 5a do not interfere with each other. Therefore, fog adjustment can be performed smoothly.

Next, another embodiment of the present invention shown in FIGS. 5 and 6 will be described. The hinge 1 'of this embodiment has a point that the whole fixing member 2' is integrally formed.
This embodiment is different from the above embodiment in that an engagement mechanism 8 'is used instead of the engagement mechanism 8. Therefore, only the differences will be described, and the same parts as those in the above embodiment will be denoted by the same reference numerals and description thereof will be omitted.

The fixing member 2 'is formed by molding a flat plate by a press or the like, and includes a guide portion 2A and a flat plate portion 2B. The guide portion 2A corresponds to the guide plate 4 of the above-described embodiment, and has a substantially U-shaped cross section in which the side of the frame B is opened by the top plate portion 2a and the side plate portions 2b and 2c connected to both sides thereof. Is formed. In the top plate 2a, a substantially square insertion hole 2d is formed instead of the long hole 4f and the rectangular hole 4g. On the other hand, the flat plate portion 2B
Corresponds to the mounting plate 3 of the above embodiment,
They are connected so as to be orthogonal to the side plates 2b and 2c.

The engaging mechanism 8 'has a contact member 9' of the engaging mechanism 8, a contact member 9 'replacing the lever 12, and a lever 12'. In the contact member 9 ′, the connecting portion 9 b is formed at the base end of the base 9 a, and the engaging piece 9 c projects from the distal end of the connecting portion 9 b toward the distal end of the connecting member 5. It is formed so that. Base 9a
Is longer than the insertion hole 2d and cannot be inserted into the insertion hole 2d, but the connecting portion 9b and the engagement piece 9c are formed so as to be inserted into the insertion hole 2d. Moreover, the connecting portion 9b
, In other words, the distance between the base 9a and the engagement piece 9c is substantially the same as the thickness of the top plate 2a. Also,
A substantially semicircular engaging recess 9e is formed on a surface of the engaging piece 9c facing the skeleton B side. On the other hand, the lever 12 'has the above-mentioned engagement concave portion between the center of rotation and the operation portion 12a.
A substantially semicircular engaging projection 12d is formed at a location facing 9e . The side surface of the engaging projection 12d facing the distal end is the inclined surface 12b.

In the hinge 1 'having the above structure, the connecting member 5
Is fixedly connected to the fixing member 2 ', the engaging portion 9c and the connecting portion 9b are inserted through the insertion hole 2d. At the same time, the adjusting screw 7 is also inserted into the large hole 5d, but since these are the same as in the above-described embodiment, the description thereof will be omitted. Next, the connecting member 5 is moved to the distal end side. Then, the inclined surface 9d of the contact member 9 'hits the inclined surface 12b of the lever 12' and pushes it down. At this time,
The urging force of the spring 13 acting on the contact member 9 'is supported by the engagement piece 9c of the contact member 9 abutting against the surface 2e of the connecting member 5 facing the pressing direction. When the inclined surface 9d gets over the inclined surface 12b, the lever 12 '
Is rotated so as to approach the contact member 9 ', and the engagement protrusion 12d is fitted into the engagement recess 9e . Thus, the connecting member 5 is immovably connected to the fixing member 2 'in the front-back direction of the frame B. Of course, in order to remove the connecting member 5, the lever 12 'may be pushed down against the urging force of the spring 13 to move the connecting member 5 from the distal end to the proximal end.

The present invention is not limited to the above-described embodiment, and the design can be changed as appropriate. For example,
In the above embodiment, the contact members 9, 9 'are provided on the connecting member 5, and the levers 12, 12' are connected to the fixing members 2, 2 '.
However, the contact members 9, 9 'may be provided on the fixing members 2, 2' and the levers 12, 12 'may be provided on the connecting member 5. In addition, the levers 12 and 12 ′ that rotate and displace are used as the displacement members, but instead of this, a displacement member that linearly displaces in the pressing direction of the connecting member 5 and in the opposite direction (the left-right direction of the frame B) is used. May be used.

[0030]

As described above, claims 1, 2, 3
According to the invention, when the connecting member is connected and fixed to the fixing member, there is no need to press the connecting member against the fixing member against the urging force of the spring, and it is sufficient to simply move the connecting member to the distal end side. Therefore, an effect is obtained that the connecting member can be easily connected and fixed to the fixing member. According to the fourth aspect of the present invention, since the movement inhibiting mechanism is constituted by the contact member and the opposing plate portion engaged with the contact member, it is not necessary to particularly form the movement inhibiting mechanism. The effect that costs can be reduced is obtained.
