Japanese Patent No. 3963858 JP 2009-167619 A Japanese Patent No. 3414706

  However, in the configuration of the known invention disclosed in Patent Document 1, when the front door (80) and the rear door (90) are completely closed, the tip (roller) of the rotating arm (15) is moved to the rear. Since it is held at a position in contact with the closed door (90), if both doors (80) (90) are opened from the closed state as shown in FIGS. The energized rotating arm (15) jumps out in an instant, and the retracted state of the rotating arm (15) when the doors (80) (90) are opened as shown in FIG. It cannot be obtained.

  Furthermore, the connecting portion (30) moving in parallel with the door opening upper frame (11) via the rotating cam (60) pressed by the rear closing door (90) as the closing of the rear closing door (90) proceeds. Since the engaging means (20) at the tip end is pulled away from the tip end (roller) of the rotating arm (15), both doors (80) and (90) as shown in FIGS. In the closed state, the rotating arm (15) is put into the retracted state so that the tip end (roller) of the rotating arm (15) is restrained from the front by the tip engaging means (20) of the connecting portion (30). It is impossible to lock.

  Moreover, since the single pivot arm (15) is pivotally supported on the summing line (F) of the front door (80) and the rear door (90), both the doors (80) are provided. In the open state of (90), the pivot arm (15) will protrude the longest from the center part of the door opening upper frame (11), impeding the design of the doorway, and by collision with other objects There is also a risk of damage.

  In this regard, in the configuration of the known invention disclosed in Patent Document 2, the first and second rotating arms (2) and (3) are in a position offset to the left and right ends of the upper frame (door frame) (100). Therefore, the rotating arms (2) and (3) project long from the center of the upper frame (door frame) (100) in the open state of both doors (101) and (102), impairing the design of the doorway. However, as the closing order, the first closed door (101) is received and held at a small crossing angle with the upper frame (100), while the rear closed door (102) is the same as the upper frame (100). Due to the relationship of receiving and holding at a large crossing angle, the first and second rotary arms (2) and (3) themselves require different construction and assembly work including accessory parts. Can not be expected to the maximum.

  Further, the first and second rotating arms (2) and (3) have a substantially U-shaped outline shape, and the second arm portions (22) that make a circular motion around the support shaft (5) of the refracting portion are, Since the link rod (4) of a certain length and the link support shaft (31) are pivotally connected to each other, the link rod (4) does not slide linearly in the left-right direction, and inevitably moves in the front-rear direction. A swinging (shaking) elliptical motion will be performed.

  Then, the result is that the square cylindrical base (1) incorporating the same is enlarged and specialized by the swinging amplitude of the link rod (4), and the second rotating arm (3) is added to the link rod (4). The lock member (50) is also built in the base (1) and combined with the special assembly, the mass production effect cannot be obtained.

  Furthermore, the first and second rotary arms (2) and (3) are pivotally supported in a undulating manner via a link rod (4) having a fixed length built in the square cylindrical base (1). Due to the connected structure, the width of the first closed door (101) and the rear closed door (102) and the length of the upper frame (door frame) (100) (opening width of the entrance / exit) are different or changed. There is a problem that the mounting state corresponding to this cannot be obtained, and the versatility in that sense is inferior.

  SUMMARY OF THE INVENTION The present invention aims to drastically solve such problems, and in order to achieve the object, in claim 1, two double doors that rotate about a vertical axis are arranged in the order of closing. In the door closing order adjusting device for closing to

  As the same configuration in which the left and right pairs of the receiving operation unit for the front closing door and the receiving operation unit for the rear closing door installed in parallel on the door opening upper frame are compatible,

  A forward-opening U-shaped actuating unit case attached and fixed to the upper frame of the door opening, an elongated rotating arm pivotally attached to the frame via a vertical rotating arm support shaft, and a rotation of the rotating arm. Attached and integrated arm actuating piece so as to be able to turn together to the moving base end part, a turning convex projecting continuously from the arm actuating piece to the rear, and a perpendicular to the tip part of the turning arm A cushion roller pivotally attached via a roller support shaft, and a vine spring wound around the rotation arm support shaft to urge the rotation arm forward from the operation unit case. Shaping,

  The slide bar extending along the left and right direction of the upper frame of the door opening is passed through both the operation unit cases of the first closing door receiving operation unit and the rear closing door receiving operation unit,

  Similarly, both the rotating protrusions of the first closing door receiving operation unit and the rear closing door receiving operation unit are removably engaged with the protrusion receiving groove formed at the corresponding position of the slide bar. As a result, the forward pivoting action of the pivoting arm protruding from the operating unit case is converted into a sliding action in which the slide bar moves linearly in the left-right direction,

  By installing a rotation pilot arm for detecting the start of closing for preventing or allowing the sliding action of the slide bar from the upper frame of the door opening toward the proximal end of the front door or the rear closing door, As long as the rotating pilot arm is not pushed down when the door is started, the slide bar does not slide, and both the rotating arm of the first closing door receiving operation unit and the second closing door receiving operation unit has its operating unit case. It is characterized in that the relationship is set so as not to protrude forward.

  Further, according to the second aspect, the slide bar is divided into at least three parts, and the intermediate portion facing the both operation unit cases of the front closing door receiving operation unit and the rear closing door receiving operation unit is welded to the reinforcing washer. Thickened, cut out the convex receiving groove in the thick part,

  The divided slide bars adjacent to each other are detachably connected outside the operation unit case so that the necessary overall length of the slide bar can be adjusted. .

  Further, according to the third aspect, both the operation unit cases of the first closing door receiving operation unit and the rear closing door receiving operation unit are attached and fixed from the front to the upper door opening frame by a pair of left and right end caps and countersunk screws. With

  Only for the operation unit case of either the first closing door receiving operation unit or the rear closing door receiving operation unit, for the non-rotatable rotating arm whose tip is in contact with the arm operating piece of the rotating arm A rotation angle adjustment piece is built in, and the rotation angle adjustment countersunk screwed to the rotation angle adjustment piece is inserted in parallel with the fixing screw from the end cap to the door opening upper frame. Let it penetrate,

  The turning angle adjusting countersunk screw is rotated from the outside, and the turning angle adjusting piece is moved back and forth along the axis of the countersunk screw, so that the turning arm is moved to the operating unit case. It is characterized in that it is configured so that the set rotation angle that projects forward from the front can be adjusted in size.

  According to the above configuration of the first aspect of the present invention, the door closing order adjusting device has a closed door start detection rotating pilot arm that is installed to project from the door opening upper frame toward the proximal end of the front door or the rear door. The slide bar extending along the left-right direction of the upper frame of the door opening does not slide unless it is pushed down from the front when the front door or the rear door is closed. Since both the rotation arms of the unit and the rear closing door receiving operation unit are set so as not to protrude forward from the operation unit case, there is an effect that the problems of the prior art described at the beginning can be solved. .

  In other words, the pivoting arm of the receiving operation unit for the first closed door and the pivoting arm of the receiving operation unit for the rear closing door do not protrude forward from the operation unit case when both doors are opened, and are pushed down into the frame. Therefore, even if the door-receiving operation unit for both doors equipped with these rotating arms is attached to the middle part of the upper frame of the door opening, the rotating arm is There is no risk of breakage or obstructing the design of the doorway (passage). On the other hand, a stable once receiving state of the front door and the rear door can be obtained, and this strengthens the receiving force (counterforce) and thus helps to improve the durability.

  In addition, the receiving operation unit for the front door and the receiving operation unit for the rear door have the same structure, and a unit body is built in the operation unit case in advance, along the left-right direction of the door opening upper frame. Since the slide bar that slides linearly passes through the operation unit case of the receiving operation unit for both doors, it not only excels in compatibility and mass production, but also changes in the length of the door opening upper frame and both There is also an effect that the mounting position can be easily changed and adjusted according to the difference in the width dimension of the door.

  Furthermore, an arm operating piece and a rotating protrusion protruding rearward are attached and integrated to the rotating base end portion of the rotating arm forming the first closing door receiving operation unit and the rear closing door receiving operation unit. On the other hand, a convex receiving groove is formed on the slide bar that penetrates and traverses the operation unit case, and the rotating convex and the convex receiving groove are engaged with each other in a freely detachable manner. Therefore, the undulating pivoting action of the pivoting arm is converted into a linear sliding action of the slide bar, and the slide bar does not sway in the front-rear direction or cause a loss of movement. As a result, the operating unit case can be flattened to the minimum necessary, and is not subject to restrictions on installation work on the door opening upper frame.

  In particular, if the configuration of claim 2 is adopted, the slide bar is divided into a plurality of pieces, so that convenience such as packing, transportation and handling can be obtained, and this can be detachably connected, By adjusting the required overall length to be longer or shorter, it is possible to easily obtain a mounting state corresponding to the change in the length of the upper frame of the door opening or the difference in width between the front door and the rear door. is there.

  Furthermore, if the structure of Claim 3 is employ | adopted, the setting arm which the rotation arm in any one of the receiving operation unit for front-closing doors and the receiving operation unit for rear-closing doors will protrude ahead from the operation unit case. The moving angle can be adjusted to be larger or smaller by rotating the rotating angle adjusting countersunk screw, and there is an effect that the receiving door can be positioned with high accuracy for the front door and the rear door.
