JP 2002-295118 A

  The door is attached so that the side edge of the door is as close as possible to the side frame when the door is closed, but as described above, the door is turned around the vertical rotation center axis, The end face of the door side edge adjacent to the part frame is inclined with respect to the side part frame as the door is rotated, so that one side of the end face approaches the side part frame. Further, as described above, the door is brought closer to the side frame by the action of the turning arm that is turned as the door is turned. For this reason, at the initial stage of the door opening operation, the degree of the end surface approaching the side frame is high. It must be set with a gap, and the wall adjacent to the side frame must also be positioned so as to avoid contact with the door.

  In view of the above points, the present invention provides a door opening / closing device capable of opening a door so that the side end face of the door does not approach the side frame side so much, and a door device equipped with such a device. The purpose is to provide.

That is, the present invention
The supporting means that is movable along the horizontal frame at least one of the upper part and the lower part of the door frame is supported so as to be rotatable around the vertical rotation center axis, and from the closed state, around the vertical rotation center axis. A door opening and closing device that opens the door opening by rotating in the forward or reverse direction,
The base end is a pivot arm that is pivotably attached to a door frame adjacent to one door side edge of the door when the door is closed, and is adjacent to the horizontal frame portion and the horizontal frame portion when the door is closed. It is arranged so as to extend between the upper or lower door horizontal edge of the door, and the tip is pivotally attached to the door horizontal edge at a position closer to the door side edge than the vertical rotation center axis. A pivot arm;
Arm attachment means for pivotally attaching the base end of the pivot arm to the door frame, wherein the pivot arm is pivoted in a first direction around the base end from a closed state. When the door is closed, the vertical axis of the first vertical axis separated from the virtual vertical plane by a predetermined distance from the virtual vertical plane on the basis of the virtual vertical plane extending in the extending direction of the horizontal edge of the door from the vertical rotation center axis of the door. When the pivot arm is pivoted around and rotated in a second direction opposite to the first direction, the first vertical axis is symmetrical with respect to the virtual vertical plane. Arm mounting means for rotating about a second vertical axis;
A door opening and closing device is provided.
According to this opening / closing apparatus, when the pivot arm is pivoted in the first direction around the base end, the pivot arm is rotated around the first vertical axis on the first direction side with respect to the virtual vertical plane. Therefore, in the predetermined angle range at the beginning of the rotation, the pivot point that is pivotally attached to the door of the pivot arm is rotated while being separated from the side frame than the position at the time of closing the door. Move. Accordingly, the door pivoted on the pivot arm also pivots while being displaced away from the side frame. That is, in the above-described conventional opening / closing device, since the base end of the rotating arm is rotated around the pivot on the virtual vertical axis, the rotation of the rotating arm is started at the same time. The above-mentioned problem has occurred because the pivot point (and hence the door) of the pivot arm with the door is displaced so as to approach the side frame. In the present invention, the pivot arm pivots. Since the pivot point (and hence the door) is moved away from the side frame within a predetermined angle range, the amount of approach of the side edge of the door to the side frame is small, and therefore the door is closed. It is possible to set the door side edge at the time closer to the side frame.

In particular,

It can be engaged and rotated in the same direction around the first pin.

Other specific examples include
The tip of the pivot arm is pivotally attached to the door horizontal edge at the center position of the door thickness when the door is closed,
The arm mounting means is
First and second pins attached to the door horizontal edge of the pivot arm, each having the first vertical axis and the second vertical axis as central axes, respectively;
A pivot guide hole is provided in the horizontal frame portion and faces the base end of the pivot arm, and engages with the first and second pins when the door is closed on a peripheral edge defining the pivot guide hole. Comprising first and second engaging portions;
When the pivot arm is pivoted in the first direction around the base end from the closed state, the first pin engages with the first engagement portion, and the first engagement portion When the pivot arm pivots about the second axis and pivots in the second direction, the second pin engages with the second engagement portion, and the pivot about the second engagement portion The arm can be rotated.

  Hereinafter, embodiments of the door device and its opening and closing device according to the present invention will be described.

  FIG. 1 is a front view of a door device 10 in a closed state according to the present invention. The door device 10 includes upper and lower horizontal frame portions 12 and 14 and side frame frames 16 and 18. The door 22 set in the door frame, the upper and lower door horizontal edge portions 24 and 26 of the door 22 and the opening and closing devices 28 and 30 set between the corresponding horizontal frame portions 12 and 14. And.

  The door 22 is suspended by a support means 34 that is movable along a rail 32 provided in the upper horizontal frame portion 12, and around a vertical rotation center axis 36 that passes through a central portion of the support means 34. It can be rotated. A rail groove (not shown) corresponding to the rail 32 is provided in the lower horizontal frame portion, and a guide pin 34 ′ provided along the vertical rotation axis 36 on the door horizontal edge portion 26 extends along the rail groove. The door 22 can be rotated around the vertical rotation axis 36 together with the support means 34 and can be moved along the upper and lower horizontal frame portions 12 and 14. I am doing so.

  Since the switchgears 28 and 30 have the same configuration, the upper switchgear 28 will be described.

  The opening / closing device 28 includes a turning arm 38, and the turning arm 38 has a base end (right end in FIG. 1) 40 of one door side edge 42 of the door 22 at the time of closing the door shown in FIG. It is attached so as to be rotatable around first and second pins 44 and 46 (FIG. 2) attached to the right end of the horizontal frame portion 12 adjacent to the horizontal frame portion 12. When the door is closed, the horizontal frame portion 12 and the door horizontal The front end 41 is pivotally attached to the door horizontal edge 24 by the pivot pin 48 at a position closer to the door side edge 42 than the vertical rotation center axis 36. Yes.

  Specifically, as shown in FIG. 2, the first and second pins 44 and 46 are extended from the vertical rotation center axis 36 passing through the center in the thickness direction of the door, and the horizontal edge 24 of the door is extended in the door when the door is closed. On both sides of the virtual vertical surface 50 extending in the direction, the first and second vertical axis lines 52 and 54 spaced from the virtual vertical surface by a predetermined distance are fixed to the horizontal frame portion 12 with the central axis line as the center axis line. The base end 40 of the arm 38 is provided with a substantially equilateral triangular rotation guide hole 56 (through the arm 38 in the vertical direction in the example shown in the figure). Two pins 44 and 46 are adapted to be engaged with the first and second vertices 58 and 60 of the rotation guide hole.

  For example, when a force indicated by F in FIG. 2 is applied to the door 22 to which such an opening / closing device 28 is attached, the door 22 is rotated in the counterclockwise direction indicated by 62 around the vertical rotation axis 36. Will be. At this time, since the pivot arm 38 is pivotally attached to the door 22 by the pivot pin 48, a rotational moment in the clockwise direction is applied as seen in FIG. It is rotated (as indicated by 64 in the locus of the pin 48).

  The rotating operation of the rotating arm 38 in this case is shown in FIG. As shown in FIG. 3, when the door 22 is pushed open by the force F as described above and rotated by 60 ° about the first pin, the third vertex 66 of the rotation guide hole 56 becomes the second pin. 46 is engaged. In this state, when the door 22 is further pushed open and a clockwise rotating moment is applied to the rotating arm 38, the rotating arm 38 is rotated around the second pin 46.

When a force in the direction opposite to the force F is applied to the door 22, the door 22 is rotated in the opposite direction 68 around the vertical rotation center axis 36, and thus the rotating arm 38 is also opposite to the above. It is rotated. Therefore, in this case, the pivot arm 38 pivots around the first pin 44 in the first 60 ° angle range from the door closing position, and around the second pin 46 in the further angle range. become.
The rotation guide hole 56 is displaced as described above with respect to the first and second pins. Therefore, the periphery of the rotation guide hole is one side of the equilateral triangle (that is, the vertices 58 and 60). , 58 and 66, the distance between 60 and 66) as a radius, an arcuate portion extending between the second and third vertices about the first vertex 58, and the second vertex 60 And an arc-shaped portion extending between the first and third vertices, and an arc-shaped portion extending between the first and second vertices with the third vertex 66 as the center. Taking FIG. 3 as an example, when the first pin 44 engages with the first vertex 58 and the pivot arm pivots about the first pin 44, the second and third vertices 60, 66 are obtained. The arcuate portion in between slides relative to the second pin 46, and the third vertex 66 engages the second pin 46, and the second pin 46 When pivoting about the 6, arcuate portion between the first and second vertices 58, 60 are adapted to slide relative to the first pin 44.

  As can be seen from the above, in this door device, when the door 22 is rotated about the vertical rotation axis 36 from the time of closing, at least in the initial predetermined angle range, the rotation arm 38 for the door is provided. The pivot point (the pivot pin 48 in the example shown in the drawing) is displaced in a direction away from the side frame 16, and draws an arc-shaped track. Therefore, the door side edge 42 is accordingly increased in the side frame 16. It becomes difficult to touch.

  In the example shown in FIG. 1, the first and second pins 44 and 46 are implanted in the mounting plate 70, and by fixing the mounting plate 70 on the upper and lower horizontal frame portions 12 and 14, It is attached to the horizontal frame. Further, the tips of the first and second pins 44 and 46 extending through the rotation guide hole 56 of the rotation arm 38 are increased in diameter as shown in the figure, and the rotation arm 38 is the first. In addition, the second pins 44 and 46 are prevented from coming out.

  FIG. 4 shows a modification of the rotation guide hole 56 of the rotation arm 38. That is, in this rotation guide hole 56, concave portions 58 ′, 60 ′, and 66 ′ are provided in portions corresponding to the first, second, and third vertices 58, 60, and 66 in the above embodiment. This is for making the rotation of the rotation arm smooth by ensuring the engagement of the first and second pins in consideration of the manufacturing error of the rotation guide hole 56 and the like.
