As for the opening / closing mechanism of the door body controlled by the portion, the one having the structure shown in the prior art document is known.

Specifically, the actuating portion is an actuating arm, and the driving device is implemented assuming that the actuating arm, a spring for rotating the actuating arm, and a holding mechanism are provided. The spring stores urging force when the actuating arm rotates to one side, and the urging force causes the actuating arm to rotate to the other side. The holding mechanism holds the actuating arm in a state of being rotated in one direction, and the receiver is implemented as receiving the actuating arm. When the actuating arm is received by the receiver, the holding of the actuating arm by the holding mechanism is released, the actuating arm is rotated to the other side by the urging force, and the urging force of the spring acts on the door body. By doing so, the door body is configured to be opened and closed by the force of the spring. In addition, a damper is installed to adjust the force of the spring and to reduce the speed of opening and closing to an appropriate speed when a person opens and closes the door vigorously.

In the case of hinged doors and folding doors in which the door body opens and closes while changing the angle with the door frame, the height may change during opening and closing depending on the weight of the door body, and the height may change due to aging. Changes can be significant. In such a case, the actuating arm may not be well accepted by the receiver, or even if it is accepted, a malfunction may occur.

Furthermore, if an opening / closing mechanism is to be provided for both opening and closing of the door body, two sets of a drive device and a receiver are required.

(overview)
As described above, in the present invention, one of the receiver 31 and the drive device 41 is the first member, and any other is the second member, and the actuating portion such as the actuating arm 42 of the drive device 41 and the receiver 31. It relates to an opening / closing mechanism of a door body that is controlled by an operating portion to open / close while changing an angle with the door frame 12 by engaging with the door body 11. The door body 11 is specifically implemented as a hinged door or a folding door, and the conventional receiver 31 and the drive device 41 are separately fixed to the door body 11 and the door frame 12, and the door body 11 is fixed. At the stage when the receiver 31 and the drive device 41 approach each other, the receiver 31 and the actuating arm 42 engage with each other to control the movement of the door body 11. We propose a new structure opening / closing mechanism in which both the receiving tool 31 and the driving device 41 are provided on either the door body 11 or the door frame 12. Specifically, both the receiver 31 and the drive device 41 are provided on either the door body 11 or the door frame 12, and at that time, either one of the receiver 31 and the drive device 41 is provided in the left-right direction. It is provided so as to be slidable, and is slidably moved by a linking member such as a linking stay 21 to engage an actuating portion such as an actuating arm 42 of the drive device 41 with a receiver 31.

(Receiver 31 and drive device 41)
In the practice of the present invention, the structure itself of the receiver 31 and the drive device 41 can be directly applied to the structure used in the conventional opening / closing mechanism, and is shown in the above-mentioned prior art document. It can be changed in various ways, such as those having a structure other than that, and the like, but the structure will be briefly described with reference to FIG. 12 as a mere example thereof.

The drive device 41 can be implemented as having an actuating arm 42, a spring 43 for rotating the actuating arm 42, and a holding mechanism 44, and in addition to this, a damper 46 can be further provided and implemented, and these can be implemented as a casing. It is stored in 47. In the example of FIG. 12, the two left and right actuating arms 42 are moved by one spring 43, but one actuating arm 42 may be moved by one spring 43, and one actuating arm 42 may be moved. It may be moved by two or more springs 43.

The actuating arm 42 is provided with an engaging portion 48 such as a roller at its tip, and its base end is rotatably supported by a casing 47 by an arm rotating shaft 49.
Both ends of the spring 43 are fixed to the force point portions 50 near the base ends of the left and right actuating arms 42, but in the case of a spring 43 having only one actuating arm 42, one end of the spring 43 is a casing 47. It is fixed to and carried out. Further, in this example, a damper 46 is used to suppress the movement of the door body 11 to a certain speed or less, and both ends of the damper 46 are fixed near the base ends of the left and right actuating arms 42, respectively. The positional relationship between the spring 43 and the damper 46 can be exchanged, or the spring 43 and the damper 46 can be connected to the actuating arm 42 via another member such as a link or a cam.

In this example, since a tension coil spring is used for the spring 43, in FIGS. 12A and 12C, the spring 43 and the damper 46 are in a contracted state, and in FIG. 12, a state in which (B) is extended. It has become. The urging force is stored in the spring 43 in this extended state, but when the compression coil spring is used for the spring 43, the urging force is stored in the spring 43 in the contracted state. This stored power is stored when the door body 11 is opened and closed by a human hand.

Specifically, in FIG. 12A, the left operating arm 42 is engaged with and fixed to the holding portion 32 of the receiver 31, and the door body 11 is opened and closed by a human hand. When the positional relationship between the receiver 31 and the drive device 41 changes, the spring 43 expands and the urging force is stored as the operating arm 42 rotates.

Further, when the opening / closing operation of the door body 11 by a human hand is continued, as shown in FIG. 12B, the left operating arm 42 comes out of the holding portion 32 to release the engaged state, and at the same time, the engaged state is released. The actuating arm 42 is held by a holding mechanism 44 such as a leaf spring. In this state, the left and right arm rotation shafts 49 and the force point portion 50 are substantially aligned with the spring 43, so that the force of the spring 43 acts as a force for rotating the operating arm 42. However, although the holding mechanism 44 keeps this state stable, the holding mechanism may be configured only by the positional relationship between the arm rotation shaft 49, the force point portion 50, and the spring 43.

Further, when the opening / closing operation of the door body 11 by human hands is continued, as shown in (C) of FIG. 12, the right operating arm 42 enters the holding portion 32 from the guide portion 33 of the receiver 31. It becomes a locked state. As a result, the force of the spring 43 acts on the door body 11, and the door body 11 rotates even with the force of the spring 43 alone. At that time, if the door body 11 moves too fast, such as when a person has a large force, the damper 46 limits the speed to an appropriate speed.
The receiver 31 is provided with a slope-shaped guide portion 33 and a recessed holding portion 32, but these may be groove-shaped, and various forms can be adopted.

(First Embodiment: FIGS. 1 to 4)
The opening / closing mechanism according to the first embodiment will be described with reference to FIGS. 1 to 4.

This opening / closing mechanism controls the opening / closing of the door body 11 by the opening / closing structure including the door body 11 and the door frame 12. In this example, a hinged door rotatably attached to the vertical frame 13 of the door frame 12 is illustrated, but it can also be applied to a folding door. The door body 11 is attached to the vertical frame 13 by a hinge (not shown) according to a conventional method, and rotates around a rotation shaft 14 to open and close.

In this example, both the receiver 31 and the drive device 41 are provided on the door body 11, and the receiver 31 is provided so as to be slidable in the left-right direction of the door body 11. Therefore, in this example, the receiver 31 is the first member, the drive device 41 is the second member, and the drive device 41, which is the second member, is fixed to the door body 11. The number of drive devices 41 may be one, but in this example, a total of two drive devices 41 are provided, one on each of the left and right sides. As a result, the control by the opening / closing mechanism is performed both when the door body 11 is fully opened and when the door body 11 is completely closed.

The receiver 31 and the drive device 41 can operate even if they are provided so as to be exposed on the outer surface of the door body 11, but they are arranged in the internal space between the front plate and the rear plate constituting the two front and rear surfaces of the door body 11. If this is done, it will be almost invisible from the outside, which is advantageous for improving the design of the living room and the like.

The receiver 31 is guided by a guide member 22 provided at the upper end of the door frame 12 and slides in the left-right direction. A rigid linking stay 21 is passed between the receiver 31 and the door frame 12 (upper frame 15 in this example) as a linking member. Both ends of the linking stay 21 are rotatably connected to the receiver 31 and the door frame 12 by connecting shafts 23 and 24, respectively. Since the receiver 31 to which the linking stay 21 is connected by the connecting shaft 24 can slide in the left-right direction of the door body 11, the receiver 31 moves in the left-right direction as the door body 11 opens and closes. The position of the connecting shaft 23 of the door frame 12 is fixed so as not to move in the left-right direction at a specific position of the door body 11.

When the receiver 31 approaches one of the drive devices 41 as the door body 11 opens and closes, the receiver 31 engages with the actuating arm 42 of the drive device 41. As a result, one of the driving devices 41 is operated and the operating arm 42 is rotated by the force of the spring 43. When the actuating arm 42 rotates, the cooperation stay 21 also rotates, whereby the door body 11 rotates with respect to the door frame 12.
When the receiver 31 is away from the left and right drive devices 41 and is in an intermediate position between the two, the force of the spring 43 does not act on the door body 11.

The connection between the connecting shafts 23 and 24 and the linking stay 21 is preferably provided with some play in the vertical direction, so that even if the door body 11 moves up and down when opening and closing, this vertical movement is performed. It is possible to absorb and smoothly move the receiver 31 in the left-right direction, and it is possible to suppress adverse effects on the engagement between the receiver 31 and the actuating arm 42 of the drive device 41.

1 (A) and 2 show a fully closed state of the door body 11. In this state, the receiver 31 is moved to the right side (door end side), and the drive device 41 on the right side. It is engaged with the actuating arm 42.
1 (B) and 3 show a state in which the door body 11 is half-opened. In this state, the receiver 31 is at an intermediate position in the left-right direction, and the actuating arm 42 of either the left or right drive device 41. Also not engaged. Therefore, the door body 11 is in a free state like a normal door.
1 (C) and 4 show a fully open state of the door body 11. In this state, the receiver 31 is moved to the left side (hanging source side), and the drive device 41 on the left side is operated. It is engaged with the arm 42.

The drive device 41 is a horizontally long type in FIG. 12 described above, but the drive device 41 in this embodiment is a vertically long type and uses two drive devices 41 having one operating arm 42. However, the form can be changed as appropriate. Further, in the case of FIG. 12, two receivers 31 were used, but in this example, the receiver 31 is moved to the left side by using one receiver 31 having a holding portion and a guide portion on each of the left and right sides. When the left holding portion and the guide portion are engaged with the operating arm 42 of the left driving device 41, and when the receiver 31 is moved to the right side, the right holding portion and the guiding portion are engaged with the operating arm 42 of the right driving device 41. It is designed to engage with, but its form can be changed as appropriate.

(Second embodiment: FIG. 5)
Next, a second embodiment will be described with reference to FIG. The opening / closing mechanism according to this embodiment is such that the door body 11 in the first embodiment can be rotated to nearly 180 degrees, and the length of the cooperation stay 21 and the length of the guide member 22. Is made longer than that of the first embodiment, or the position of the connecting shaft 23 is changed so that it can correspond to a large rotation range.

(Third Embodiment: FIGS. 6 to 8)
The opening / closing mechanism according to the third embodiment will be described with reference to FIGS. 6 to 8.
In this opening / closing mechanism, both the receiving tool 31 and the driving device 41 are provided on the door frame 12 side, and the receiving tool 31 is provided so as to be slidable in the left-right direction of the upper frame 15 of the door frame 12. .. Therefore, in this example as well, the receiver 31 is the first member and the drive device 41 is the second member, but unlike the first embodiment, both are provided on the door frame 12 side. The drive device 41, which is the second member, may be one, but in this example, two are provided on the left and right. As a result, the control by the opening / closing mechanism is performed both when the door body 11 is fully opened and when the door body 11 is completely closed.

The guide member 22 for guiding the receiver 31 in the left-right direction is provided on the lower surface of the upper frame 15 of the door frame 12, and the connecting shaft 23 of the cooperation stay 21 is provided on the receiver 31 on the door frame 12 side. There is.

In this state, the receiver 31 is located at an intermediate position between the left and right, and is not engaged with the operating arm 42 of either the left or right drive device 41. Therefore, the door body 11 is in a free state like a normal door.
FIG. 8 shows a fully open state of the door body 11. In this state, the receiver 31 moves to the left side (hanging source side) and engages with the actuating arm 42 of the drive device 41 on the left side. ing.

(Fourth Embodiment: FIGS. 9 to 12)
The opening / closing mechanism according to the fourth embodiment will be described with reference to FIGS. 9 to 12.

In this opening / closing mechanism, both the receiver 31 and the drive device 41 are provided on the door body 11 side, and the drive device 41 is provided so as to be slidable in the left-right direction of the door body 11. Therefore, in this example, the drive device 41 is the first member and the receiver 31 is the second member, both of which are provided on the door body 11 side. The second member, the receiver 31, may be one, but in this example, two are provided on the left and right. As a result, the control by the opening / closing mechanism is performed both when the door body 11 is fully opened and when the door body 11 is completely closed.
In this example, the drive device 41 is the horizontally long type shown in FIG. 12, which was first described, but may be a vertically long type.

FIG. 9A shows an example of a form in which the receiver 31 and the drive device 41 are housed in the door body 11, and the upper portion of the drive device 41 is provided with a guided portion 45 projecting in the front-rear direction. Correspondingly, the guide member 22 has a U-shaped cross section, and the guided portion 45 is received and can be guided from above and below the guide member 22 so as to obtain a stable operating state in the vertical direction. Is.
In this example, the actuating arm 42 protruding below the drive device 41 engages with the receiver 31 provided below the actuating arm 42, and is arranged in the recess provided in the door body 11.

9 (B) and 9 (C) show the fully closed state of the door body 11. In this state, the drive device 41 is moving to the right side (door end side), and the operating arm 42 is on the right side. It is engaged with the receiver 31 of.

(Change example)
The present invention can be carried out in various forms as in the above-described embodiment.

The receiver 31 and the drive device 41 can be implemented as a first member that slides in the left-right direction, and either one can be implemented as a fixed second member. Any of the drive devices 41 may be the first member.

The receiving tool 31 and the driving device 41 may be provided in any of the opening / closing structures including the door body 11 and the door frame 12.

Although two fixed second members are shown in the figure, one may be used. In that case, it does not matter whether the door body operates when it is fully open or when it is fully closed.

The opening / closing angles of the door body 11 are shown to be about 90 ° and about 180 °, but the angles can be changed as appropriate.

It can be carried out regardless of the weight of the door, and especially when the weight of the door is heavy, the weight of the door makes it easy for the door tip to move up and down during opening and closing. By providing the tool 31 and the drive device 41 together in one of the door body 11 and the door frame 12, it is possible to suppress the influence of the vertical movement during opening and closing.

When the door body 11 is fully closed, a latch is generally provided in order to hold the closed state, but a mechanism for assisting the closing of the latch may be added.

With the door body 11 fully open, you may add a mechanism that can prevent it from being agitated, make the opening and closing mechanism compact, and add various adjustment mechanisms such as up / down, left / right, and pull-in speed. It does not matter if it is carried out.

(Advantages of the embodiment)
The greatest effect of the present invention is that it was possible to provide a new structure of an opening / closing mechanism that has never existed before, but this new structure makes it possible to implement the opening / closing mechanism having various advantages. rice field.

In the conventional opening / closing mechanism, it may be necessary to change the shape structure of the drive device 41 depending on whether the door body 11 opens to the right or left, but in the present invention, the opening / closing mechanism does not seem to be left-right. Can be carried out.

With the conventional opening / closing mechanism, it is difficult to deal with the opening of the door, and therefore it is necessary to provide a separate door stop on the floor surface. However, in the present invention, only the opening / closing mechanism is used for opening and closing. Since the door body 11 can be stopped at a desired position on the side, it is possible to carry out the work without providing a door stop on either the open side or the closed side. Therefore, it is possible to carry out without providing a separate door stop on the open door side, and it is also possible to omit the frame door stop provided on the door frame on the closed door side, and further, packing for shock absorption and There are advantages such as no need for mohair.

In the present invention, since the opening / closing mechanism can be built into the door body 11 and the door frame 12, only the cooperation stay can be seen from the outside. This makes it possible to create a structure that is advantageous for improving the aesthetic appearance, which is a major point in housing equipment.
