It is configured to adjust the closing order of the two doors by being in the projecting state.

  The base 21 is a member that serves as an installation reference of the door closing priority adjuster 100 according to the present embodiment by being fixedly installed on the upper frame. The base 21 is provided with a plurality of mounting holes (not shown) in its body portion, and by using these mounting holes, reliable fixing to the upper frame is realized. Moreover, the base 21 has the axial body 23 formed so that an axial direction may be extended in the perpendicular direction at the time of fixed installation to an upper frame. The shaft 23 plays a role as a pivoting central axis in the pivoting operation of the arm 31 by pivotally connecting an arm 31 described later. Furthermore, the base 21 is provided with a second arm fixing hole 25 for fixing a second arm 41 described later (see FIG. 4).

  The arm 31 is a member that protrudes from the upper frame side in the opening direction of the door and supports the rear closing door 13, and therefore, is configured as a structural member whose longitudinal cross section is formed in a rectangular shape. The arm 31 is rotatably installed via the base 21 and the shaft 23, but between the base 21 and the arm 31, the arm 31 protrudes in the direction of opening the door from the upper frame side. In addition, a coil spring (not shown) as an elastic body that always exerts a biasing force on the arm 31 is installed. In addition, a roller 33 is rotatably provided on the tip end side of the arm 31 so that smooth sliding contact with the rear closing door 13 can be realized. Further, on the upper surface of the arm 31, a recess 35 is formed to be engaged with a projection 55 of the second arm 41 described later. The recess 35 may be configured as a groove with respect to the arm 31 or may be configured as a through hole.

  The second arm 41 is the most characteristic member constituting the door closing priority adjuster 100 according to the present embodiment. As the constituent material, flexible materials such as resin and rubber are adopted. The second arm 41 is formed to be substantially in a straight line when the two-sheet door is closed. On the other hand, when the two-sheet door is in contact with the arm 31 which is open and in the projecting state, one side of the two hinges 47, 47 is broken, and in this state, the initial state of the second arm 41 In order to recover the substantially straight line state, the biasing force is exerted on the direction of the arm 31.

  As shown in FIG. 2, the second arm 41 is provided with a fixing portion 43 fixed to the base 21, a connecting portion 45 connecting with the arm 31, and two hinges provided between the fixing portion 43 and the connecting portion 45. Parts 47 and 47.

  As shown in FIG. 1 and FIG. 2, the fixing portion 43 is formed in the vicinity of the insertion hole 49 for fixing the second arm 41 to the base 21, the insertion hole 49 into which the fixation pin 61 is inserted, and And a claw portion 51 to be formed.

  The fixing pin 61 is made of a resin material, and as shown in FIG. 3, the fixing pin 61 has a large diameter portion 63 with a large outer diameter, a groove 65 formed in the large diameter portion 63, and a large diameter portion And a small diameter portion 67 having a diameter smaller than 63.

  The claw portion 51 is made of, for example, a flexible material such as resin or rubber. In the present embodiment, as shown in FIG. 2, four claws 51 are formed and arranged at equal intervals in the vicinity of the insertion hole 49, but the number and arrangement thereof can be appropriately changed.

  In order to fix the second arm 41 to the base 21, as shown in FIG. 4A, the fixing pin 61 is inserted into the insertion hole 49 and the tip 51 a of the claw portion 51 is the one of the fixing pin 61. The fixing portion 43 of the second arm 41 disposed in the vicinity of the small diameter portion 67 is inserted into the second arm fixing hole 25 to bring about a state shown in FIG. 4B. Then, by pushing the fixing pin 61 into the second arm fixing hole 25, as shown in FIG. 4 (c), the claw portion 51 is pressed by the large diameter portion 63 and is bent outward and the second arm The second arm 41 is fixed to the base 21 by being hooked to the edge of the fixing hole 25 and by fitting the tip end 51a of the claw 51 to the groove 65. By fixing the second arm 41 to the base 21 using the fixing pin 61, the door closing priority adjuster 100 according to the present embodiment does not release the second arm 41 unless the fixing pin 61 is pulled out. It is possible to realize stronger fixation of the second arm 41 to the base 21 than the technology. When the second arm 41 is removed from the base 21, the fixing pin 61 is pulled out to be in the state shown in FIG. 4B, and then the second arm 41 is removed from the base 21.

  As shown in FIG. 2, the connection portion 45 is configured to include a collar portion 53 for holding the arm 31 and a convex portion 55 engaged with the concave portion 35 formed in the arm 31.

  The collar portion 53 is formed at the tip of the arm 31 and configured to grip and hold the arm 31. The protrusion 55 is configured to engage with the recess 35 formed in the arm 31. The second arm 41 according to the present embodiment can maintain the contact state with the arm 31 at all times by the biasing force for recovering the initial state, the flange portion 53 and the convex portion 55.

  The hinge portion 47 can be bent from the portion by thinning the second arm 41. The hinge part 47 which concerns on this embodiment thins the 2nd arm 41 by forming one substantially triangular notch in the front side or back side of the 2nd arm 41, as shown in FIG. The second arm 41 can be bent about the portion 47. However, the method of forming the hinge portion 47 is not limited to this, and it is sufficient if it can be bent from the portion, for example, as a substantially triangular notch is formed on the front side and the back side to form the hinge portion. It is also good.

  The 2nd arm 41 concerning this embodiment is provided with two hinge parts 47, and is constituted. With such a configuration, even when the two-sheet door is pushed in more than the closed position, the hinge portion 47 is bent to release the pressing force from the rear closing door 13 and the pressing force is the fixing of the second arm 41. It does not reach the portion 43, and no load is applied to the fixing portion 43 of the second arm 41, and the fixing of the second arm 41 to the base 21 is not released. Therefore, according to the present embodiment, it is possible to provide the door closing priority adjuster 100 including the second arm 41 which is more rigidly fixed to the base 21.

  The configuration example of the door closing priority adjuster 100 according to the present embodiment has been described above. Next, an operation example of the door closing priority adjuster 100 according to the present embodiment will be described using FIGS. 5 and 6. Here, FIG. 5 is a figure for demonstrating the operation | movement of the door closing order | rank adjustment | control which concerns on this embodiment, The division figure (a) in FIG. It is an external appearance top view which shows an adjuster, and the division figure (b) in FIG. 5 is an external appearance top view which shows the door closing order | rank adjuster in the state which 2 sheets of doors closed. Moreover, FIG. 6 is a figure which shows the door closing priority regulator which concerns on this embodiment when two sheets of doors are pushed in from the closing position.

  In the initial state in which the two doors are open, the arm 31 abuts and supports the rear closing door 13 to prevent the rear closing door 13 from closing earlier than the front closing door 11. That is, in the door closing priority adjuster 100 according to the present embodiment, the arm 31 in the projecting state is in contact with the rear closing door 13 via the roller 33 so that the rear closing door 13 is not closed before the front closing door 11 is closed. As a result, the rear closing door 13 is retracted from the operation range of the front closing door 11 (inside of the arc of a two-dot chain line indicated by a symbol α). Then, when the front-closing door 11 pivots while drawing a locus of a two-dot chain line indicated by a symbol α, the second arm 41 is installed between the arm 31 and the front-closing door 11, so the arm 31 The pressure from the front closing door 11 via the arm 41 is received. The second arm 41 is bent in the opening direction of the door centering on the hinge portion 47 when the two-sheet door is in contact with the arm 31 which is in the open state and is in the projecting state. Because it tries to recover, the biasing force is exerted on the direction of the arm 31.

  When the front door 11 is rotated and the pressure on the second arm 41 is advanced, the flange portion 53 of the second arm 41 presses and slides on the side surface of the arm 31 and the convex portion 55 of the second arm 41 is arm 31 By sliding while engaging with the concave portion 35, the front door 11 is closed. Also at this time, because the second arm 41 is made of a flexible material such as resin or rubber, the influence on the arm 31 can be minimized, and noise can be prevented. Furthermore, since the second arm 41 has a gentle contact surface with the front door 11, the smooth and quiet closing operation is realized.

  On the other hand, since the arm 31 slides on the inside of the rear closing door 13 simultaneously with the pressing operation of the second arm 41 by the front closing door 11, the arm 31 rotates in the closing direction. That is, since the front-closing door 11 presses the arm 31 and rotates the arm 31 to the upper frame side against the biasing force of the elastic body (not shown), the operation range of the front-closing door 11 (two points indicated by a symbol α Invasion of the rear closing door 13 into the inside of the dashed circular arc) is permitted. Then, the rear closing door 13 gradually closes while receiving the restriction of the sliding arm 31, and when closing of the two-sheet door is finally completed, the door closing priority adjuster 100 according to the present embodiment is shown in FIG. The arm 31 is held substantially parallel to the door surface of the front door 11 as shown in FIG.

  In the door closing priority adjuster 100 shown in the part (b) of FIG. 5, the mounting position is the second on the extension of the closing surface of the two-sheet door (the alternate long and short dash line indicated by symbol β). The case where the connection portion 45 of the arm 41 and the arm 31 are disposed is illustrated. However, since the second arm 41 according to the present embodiment has a shape having a certain length, the error in the mounting position in the left-right direction (left-right direction in FIG. 5) is also absorbed with a margin. There is no restriction on the mounting position depending on the type of door.

  Further, in the door closing priority adjuster 100 shown in the part (b) of FIG. 5, when the two-sheet door is further pushed in, according to the related art, the rear closing door 13 is dependent on the mounting position of the door closing priority adjuster. The second arm may be loaded by the pressing force of the second arm, and the second arm may be released from being fixed to the base. However, since the second arm 41 according to the present embodiment is configured to have the two hinge portions 47, 47, when the two-sheet door is further pushed, as shown in FIG. By pressing the portions 47 and 47 into a substantially S-shape, the pressing force of the rear closing door 13 can be released, no load is applied to the fixing portion 43 of the second arm 41, and the fixing of the second arm 41 to the base 21 is released. You will not be Therefore, according to the present embodiment, it is possible to provide the door closing priority adjuster 100 including the second arm 41 that is more rigidly fixed to the base 21.

  As mentioned above, although the suitable embodiment of the present invention was described, the technical scope of the present invention is not limited to the range given in the above-mentioned embodiment. It is possible to add various change or improvement to the above-mentioned embodiment.

  For example, the shape of the second arm 41 is not limited to the form shown in the drawing, and modifications can be made within the range in which the same effects can be exhibited.

  It is also apparent from the scope of the claims that the embodiments added with such alterations or improvements can be included in the technical scope of the present invention.
