Description

Opening and closing mechanism of door body

Technical Field

The present invention relates to an opening and closing mechanism for a door.

Background

As for the opening and closing mechanism of the door body including the first member of either one of the driving device and the receiver and the second member of either one of the other, the opening and closing mechanism of the door body is known as shown in the prior art document, in which the door body is controlled by the operating portion to open and close by engaging the operating portion of the driving device with the receiver.

Specifically, the operating unit is an operating arm, and the driving device is implemented to include the operating arm, a spring for pivoting the operating arm, and a holding mechanism. The spring accumulates an urging force when the operation arm is rotated in one direction, and the operation arm is rotated in the other direction by the urging force. The holding mechanism holds the operation arm in a state where the operation arm is rotated in one direction, and the receiving member is configured to receive the operation arm. The operation arm is received by the receiver, the operation arm is released from being held by the holding mechanism, the operation arm is rotated to the other side by the urging force, the door body is opened and closed by the urging force of the spring due to the urging force of the spring acting on the door body. Further, a damper is attached to adjust the force of the spring or reduce the opening/closing speed to an appropriate speed when a person opens or closes the door body vigorously.

In a vertical hinged door or a folding door that opens and closes while changing the angle between the door body and the door frame, the height may change during opening and closing depending on the weight of the door body, and the change in height may become significant due to the change over time. In such a case, the operating arm may not be received properly by the receiving member, or may malfunction if received.

Further, if the opening and closing mechanism is provided for both opening and closing of the door body, two sets of driving devices and receiving members are required.

Problems to be solved by the invention

The invention provides a new structure in an opening and closing mechanism of a door body.

Another object of the present invention is to provide an opening/closing mechanism for a door body, which suppresses the influence of a change in height of the opening/closing mechanism when a vertical hinged door or a folding door is opened or closed.

It is another object of the present invention to provide an opening/closing mechanism for a door that can cope with both opening and closing of the door.

Means for solving the problems

The present invention provides a novel structure in an opening and closing mechanism of a door body, wherein the opening and closing mechanism of the door body is provided with a first member of any one of a driving device and a receiving piece and a second member of any other one, and the door body is controlled by an action part of the driving device and the receiving piece through the action part in a manner of changing an angle with a door frame and opening and closing the door body.

That is, in the present invention, the door body may be implemented as a side hung door or a folding door, and both the first member and the second member are provided in an opening/closing structure of either the door body or the door frame. The first member is slidable in the left-right direction, but the second member is not movable in the left-right direction.

The other opening/closing structure of the door body and the door frame is connected to the first member via an interlocking member. The linking member slides the first member along the one opening/closing structure in accordance with the opening/closing of the one opening/closing structure. By this sliding movement, the operating portion of the drive device engages with the receiving member, and the door is controlled by the operating portion to open and close.

Effects of the invention

In the present invention, since both the first member and the second member are provided in the opening/closing structure of either the door body or the door frame, the opening/closing mechanism can be prevented from being affected by a change in height when the vertical hinged door or the folding door is opened or closed.

Detailed Description

Hereinafter, embodiments of the present invention will be described with reference to the drawings.

(summary)

As described above, the present invention relates to an opening and closing mechanism for a door body, in which one of the receiver 31 and the driving device 41 is a first member, and the other is a second member, and an operating portion such as the operating arm 42 of the driving device 41 is engaged with the receiver 31, whereby the door body 11 is controlled by the operating portion to open and close while changing the angle with respect to the door frame 12. Specifically, the door body 11 is implemented as a side hung door or a folding door, and conventionally, the receiver 31 and the driving device 41 are separately fixed to the door body 11 and the door frame 12, and the receiver 31 engages with the operation arm 42 to control the operation of the door body 11 at a stage when the receiver 31 and the driving device 41 approach each other such as when the door body 11 approaches full closure, and a new opening and closing mechanism in which both the receiver 31 and the driving device 41 are provided in either one of the door body 11 and the door frame 12 has been proposed in the present invention. Specifically, the receiver 31 and the driving device 41 are provided together on either one of the door body 11 and the door frame 12, and at this time, either one of the receiver 31 and the driving device 41 is slidably provided in the left-right direction, and is slidably moved by a linking member such as the linking stay 21, and the operating portion such as the operating arm 42 of the driving device 41 is engaged with the receiver 31.

(receiving member 31 and driving device 41)

In the embodiment of the present invention, the structure itself of the socket 31 and the driving device 41 can be applied as it is to the structure used in the conventional opening and closing mechanism, and the structure shown in the above-described prior art document, the other structure, and the like can be variously modified and implemented, but as a simple example thereof, the structure thereof will be briefly described with reference to fig. 12.

The driving device 41 may be implemented as a device including the operating arm 42, the spring 43 for rotating the operating arm, and the holding mechanism 44, and may be implemented by further providing a damper 46, which is housed in a case 47. In the example of fig. 12, the left and right two operating arms 42 are operated by one spring 43, but one operating arm 42 may be operated by one spring 43, or one operating arm 42 may be operated by two or more springs 43.

The operation arm 42 includes an engagement portion 48 such as a roller at its distal end, and its proximal end is pivotally supported by the housing 47 via an arm pivot 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 operating arms 42, respectively, but in the case where only one operating arm 42 is provided, one end of the spring 43 is fixed to the housing 47. In this example, the damper 46 is used to suppress the motion of the door 11 to a constant speed or less, and both ends of the damper 46 are fixed to the right and left operation arms 42 near the base ends thereof. The positional relationship between the spring 43 and the damper 46 may be changed, and the spring 43 and the damper 46 may be connected to the operating arm 42 via another member such as a link or a cam.

In this example, since the spring 43 is a tension coil spring, in fig. 12, (a) and (C) are in a state where the spring 43 and the damper 46 are contracted, and (B) is in an extended state. In this extended state, the spring 43 stores an urging force, but when the spring 43 is a compression coil spring, the spring 43 stores an urging force in a contracted state. The accumulated force is accumulated when the door body 11 is opened and closed by a hand of a person.

Specifically, in fig. 12 (a), in a state where the left-side operation arm 42 is engaged with and fixed to the holding portion 32 of the receiver 31, when the positional relationship between the receiver 31 and the drive device 41 changes during the opening and closing operation of the door body 11 by the human hand, the spring 43 expands and accumulates the urging force as the operation arm 42 rotates.

When the opening and closing operation of the door 11 by the hand of the person is continued, as shown in fig. 12 (B), the left-side operation arm 42 is pulled out from the holding portion 32 to release the engagement state, and the operation arm 42 is held by the holding mechanism 44 such as a leaf spring. In this state, since the right and left arm turning shafts 49 and the force point portions 50 are substantially aligned with the spring 43, the force of the spring 43 does not act greatly as a force for turning the operation arm 42, and the holding mechanism 44 stably holds this state, but the holding mechanism may be configured only by the positional relationship of the arm turning shafts 49, the force point portions 50, and the spring 43.

When the opening and closing operation of the door body 11 by the hand of the person is continued, as shown in fig. 12 (C), the right operating arm 42 enters the holding portion 32 from the guide portion 33 of the receiver 31, and becomes the locked state. Accordingly, the force of the spring 43 acts on the door 11, and the door 11 rotates only by the force of the spring 43. At this time, when the movement of the door 11 is too fast, such as when the force of a person is large, the damper 46 limits the movement to an appropriate speed.

The receiving member 31 includes the guide portion 33 having a slanted shape and the holding portion 32 having a recessed portion, but these may be formed in a groove shape, and various forms may be adopted.

(first embodiment: FIGS. 1 to 4)

The opening and closing mechanism according to the first embodiment will be described with reference to fig. 1 to 4.

The opening/closing mechanism controls the opening/closing of the door 11 by an opening/closing structure composed of the door 11 and the door frame 12. In this example, a side hung door rotatably attached to the vertical frame 13 of the door frame 12 is illustrated, but the present invention can also be applied to a folding door. The door 11 is attached to the vertical frame 13 by a hinge (not shown) in a conventional manner, and is opened and closed by being rotated about a rotation shaft 14.

In this example, the socket 31 and the driving device 41 are both provided on the door body 11, and the socket 31 is provided slidably in the right-left direction of the door body 11. Therefore, in this example, the receiver 31 is a first member, the driving device 41 is a second member, and the driving device 41 as the second member is fixed to the door body 11. One driving device 41 may be provided, but in this example, one driving device 41 is provided on each of the right and left sides, and the total number of the driving devices 41 is two. Thus, the control by the opening/closing mechanism is performed both when the door 11 is fully opened and when it is fully closed.

The receiver 31 and the driving device 41 operate even when they are disposed so as to be exposed to the outer surface of the door body 11, but if they are disposed in the inner space between the front plate and the rear plate that constitute both the front and rear surfaces of the door body 11, they are in a state of being hardly visible from the outside, and therefore, they are advantageous in improving the design of the living room space and the like.

The receiver 31 is guided by the guide member 22 provided at the upper end of the door frame 12 and slides in the left-right direction. A rigid interlocking stay 21 is provided as an interlocking member between the receiver 31 and the door frame 12 (in this example, the upper frame 15). Both ends of the interlocking stay 21 are rotatably connected to the socket 31 and the door frame 12 by the connecting

shafts

23 and 24, respectively. Since the receiver 31 to which the linking stay 21 is connected by the connecting shaft 24 is slidable in the left-right direction of the door 11, the receiver 31 moves in the left-right direction in accordance with the opening and closing of the door 11. The position of the coupling shaft 23 of the door frame 12 is fixed so as not to move in the right and left direction at a specific position of the door body 11.

When the receiver 31 approaches one of the driving devices 41 as the door 11 is opened and closed, the receiver 31 engages with the operation arm 42 of the driving device 41. Thereby, one of the driving devices 41 is operated, and the operating arm 42 is rotated by the force of the spring 43. The operating arm 42 rotates, and the linking stay 21 also rotates, whereby the door 11 rotates relative to the door frame 12. When the receiver 31 is located at a position intermediate between the left and right driving devices 41, the force of the spring 43 does not act on the door body 11.

Further, the connection between the connecting

shafts

23 and 24 and the linking support 21 preferably has a slight play in the vertical direction, so that even if the door body 11 moves vertically during opening and closing, the vertical movement can be absorbed to smoothly move the receiver 31 in the left-right direction, and adverse effects on the engagement between the receiver 31 and the operation arm 42 of the drive device 41 can be suppressed.

Fig. 1 a and 2 show a fully closed state of the door body 11, in which the receiver 31 moves to the right side (door front side) and engages with the operating arm 42 of the right-side drive device 41.

Fig. 1 (B) and 3 show a state in which the door body 11 is half-opened, and in this state, the receiver 31 is positioned at an intermediate position in the left-right direction and does not engage with the operating arm 42 of any one of the left and right driving devices 41. Therefore, the door 11 is in a free state as in a normal door.

Fig. 1C and 4 show a fully open state of the door body 11, in which the receiver 31 moves to the left (hinge attachment side) and engages with the operating arm 42 of the left drive device 41.

Although the driving device 41 is shown as a horizontally long type in fig. 12, the driving device 41 of this embodiment uses two vertically long types of driving devices 41 having 1 operation arm 42, but the mode can be changed as appropriate. In the configuration of fig. 12, two receptacles 31 are used, but in this example, one receptacle 31 having a holding portion and a guide portion on each of the left and right sides is used, and when the receptacle 31 moves to the left, the holding portion and the guide portion on the left side engage with the operating arm 42 of the left driving device 41, and when the receptacle 31 moves to the right, the holding portion and the guide portion on the right side engage with the operating arm 42 of the right driving device 41.

(second embodiment: FIG. 5)

Next, a second embodiment will be described with reference to fig. 5. The opening/closing mechanism of this embodiment can rotate the door 11 in the first embodiment to approximately 180 degrees, and can also cope with a wide rotation range by making the length of the linking stay 21 and the length of the guide member 22 longer than those of the first embodiment, or by changing the position of the connecting shaft 23.

(third embodiment: FIGS. 6 to 8)

An opening/closing mechanism according to a third embodiment will be described with reference to fig. 6 to 8.

In this opening/closing mechanism, both the socket 31 and the driving device 41 are provided on the door frame 12 side, and the socket 31 is provided slidably in the left-right direction of the upper frame 15 of the door frame 12. Therefore, in this example, the socket 31 is also the first member, and the driving device 41 is also the second member, but unlike the first embodiment, both are provided on the door frame 12 side. One driving device 41 as the second member may be provided, but two driving devices are provided on the left and right sides in this example. Thus, the control by the opening/closing mechanism is performed both when the door 11 is fully opened and when it is fully closed.

A 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 a connection shaft 23 of the linkage stay 21 is provided on the receiver 31 on the door frame 12 side.

Fig. 6 shows a fully closed state of the door body 11, in which the receiver 31 moves to the right (door front side) and engages with the operating arm 42 of the right drive device 41.

Fig. 7 shows a state in which the door body 11 is half-opened, and in this state, the receiver 31 is positioned at the intermediate position between the left and right and does not engage with the operating arm 42 of any one of the left and right driving devices 41. Therefore, the door 11 is in a free state as in the case of a normal door.

Fig. 8 shows a fully open state of the door body 11, in which the receiver 31 moves to the left (hinge attachment side) and engages with the operating arm 42 of the left drive device 41.

(fourth embodiment: FIGS. 9 to 12)

An opening/closing mechanism according to a fourth embodiment will be described with reference to fig. 9 to 12.

In this opening/closing mechanism, the receiver 31 and the driving device 41 are both provided on the door body 11 side, and the driving device 41 is provided slidably in the left-right direction of the door body 11. Therefore, in this example, the driving device 41 is a first member, and the receiver 31 is a second member, both of which are provided on the door body 11 side. The second member may be one receiving member 31, but in this example, two receiving members are provided on the left and right. Thus, the control by the opening/closing mechanism is performed both when the door 11 is fully opened and when it is fully closed.

In this example, the horizontally long type driving device of fig. 12 described above is used as the driving device 41, but a vertically long type driving device may be used.

Fig. 9 (a) shows an example of a mode of housing the socket 31 and the driving device 41 in the door body 11, and the upper portion of the driving device 41 is provided with a guided portion 45 protruding in the front-rear direction. Correspondingly, the guide member 22 is formed in a cross section コ, and can be guided from above and below while accommodating the guided portion 45, thereby obtaining a stable operating state in the up-down direction.

In this example, the actuating arm 42 protruding below the driving device 41 is engaged with the receiving member 31 provided below the actuating arm, and is disposed in the recess provided in the door body 11.

Fig. 9 (B) and (C) show a fully closed state of the door body 11, in which the driving device 41 moves to the right side (door front side) and the operating arm 42 engages with the right receiver 31.

Fig. 10 (a) and (B) show a state in which the door 11 is half-opened, and in this state, the driving device 41 is positioned at the intermediate position between the left and right, and the operating arm 42 is not engaged with any of the left and right receivers 31. Therefore, the door 11 is in a free state as in the case of a normal door.

Fig. 11 (a) and (B) show a fully open state of the door body 11, in which the drive device 41 moves to the left (hinge attachment side) and the actuating arm 42 engages with the left receiver 31.

(modification example)

The present invention can be implemented in various ways as in the above-described embodiments.

Any one of the socket 31 and the driving device 41 can be implemented as a first member that slides in the left-right direction, and any other one can be implemented as a fixed second member, and neither the socket 31 nor the driving device 41 can be implemented as a first member.

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

The fixed second member is shown in two, but may also be implemented by one member. In this case, the operation may be performed when the door is fully opened or when the door is fully closed, and neither case is problematic.

The opening and closing angle of the door 11 is about 90 ° or about 180 °, and the angle can be changed as appropriate.

Since the door can be implemented regardless of the weight of the door, and particularly when the door is heavy, the door front side is likely to move up and down during opening and closing due to the weight of the door, the receiving tool 31 and the driving device 41 are collectively provided on one of the door 11 and the door frame 12 as in the present invention, and thus the influence of the up and down movement during opening and closing can be suppressed.

When the door 11 is fully closed, a latch is generally provided to keep the door closed, but a mechanism for assisting in closing the door may be additionally provided.

In the fully opened state of the door 11, a mechanism capable of stopping the door may be additionally provided, and various adjustment mechanisms for making the opening and closing mechanism compact, for example, up and down, left and right, and the pulling speed may be additionally provided.

(advantages of the embodiments)

The present invention has a great effect of providing a new structure of an opening and closing mechanism which has not been available in the past, and the present invention can be implemented as an opening and closing mechanism having various advantages by the new structure.

In the conventional opening and closing mechanism, the shape and structure of the driving device 41 may need to be changed depending on whether the door 11 is opened rightward or leftward.

In the conventional opening and closing mechanism, it is difficult to deal with when opening the door, and therefore, it is necessary to provide a separate door stop on the floor, but in the present invention, the door 11 can be stopped at a desired position on the opening side or the closing side only by the opening and closing mechanism, and therefore, the opening and closing mechanism can be implemented without providing a door stop on either of the opening side or the closing side. Therefore, the present invention can be implemented without providing a separate door stop on the door opening side, and can also be implemented without providing a frame door stop provided on the door frame on the door closing side.

In the present invention, the opening and closing mechanism can be implemented by being incorporated in the door body 11 and the door frame 12, and therefore, the interlocking stay can be implemented by being viewed only from the outside. This makes it possible to provide a structure advantageous for improving the aesthetic appearance of a large element in a housing facility.
