  The connecting member 22 includes a base 31 having a rectangular shape as a whole. The base 31 includes a shaft insertion portion 37 into which the first shaft 23a is inserted at one end on the first fixing bracket 21a side in the length direction. The base 31 has a thicker region 33a on the other end side than the one end side, and the region 33a on the other end side includes a slide hole 32 through which the second shaft 23b is inserted. The slide hole 32 is a long hole extending in the L direction of the base 31 corresponding to the width direction of the panels 10a and 10b, and is configured such that the second shaft 23b can move in the L direction. Further, one of the opposing inner surfaces of the slide hole 32 is provided with a recess 34 with which the second shaft 23b is engaged. The recess 34 is located not near the other end of the slide hole 32 but near the other end. That is, in the slide hole 32, the inner surface provided with the recess 34 is configured by a first flat portion 32 a extending from one end to the recess 34, a recess 34, and a second flat portion 32 b extending from the recess 34 to the other end. Yes. The recess 34 functions as an intermediate stopper that temporarily stops the movement of the second shaft 23b. The second plane portion 32b is shorter than the first plane portion 32a. One surface of the region 33 a on the other end side includes an opening 35.

  The opening 35 is provided with a pressing member that presses the second shaft 23b in the direction of the inner surface of the slide hole 32 having the recess 34. Specifically, a shaft pressing member 41 and an elastic member 46 are disposed in the opening 35 as pressing members. The opening 35 has a rectangular shape and is continuous with the slide hole 32, and includes a guide recess 36 on a wall facing in the W direction corresponding to the vertical (height) direction of the panels 10a and 10b.

  The shaft pressing member 41 is fitted in the opening 35 and moves in the T direction, which is the thickness direction of the base 31. Specifically, the shaft pressing member 41 includes guide protrusions 42 that are engaged with the guide recesses 36 on opposing walls in the W direction, and L that defines an opening 35 on the opposing walls in the L direction. A guide wall 43 that abuts against opposite side walls is provided. The shaft pressing member 41 has a flat surface 41a as a pressing surface for pressing the second shaft 23b inserted into the slide hole 32. Since the pressing surface that presses the second shaft 23b is configured by the flat surface 41a, the second shaft 23b can easily slide with respect to the flat surface 41a. The surface opposite to the pressing surface of the shaft pressing member 41 is an outer surface 41 b that faces the elastic member 46. The outer surface 41b is provided with a protruding portion 44 of a protrusion to which the elastic member 46 is in line contact. The protrusion 44 is configured by a protrusion that extends linearly in the width W direction.

  The elastic member 46 is a leaf spring, for example, and has a rectangular plate shape. The elastic member 46 includes a through hole 47 at one end in the L direction. A fixing hole 48 a is provided in a region 33 b on one end side in the L direction of the base 31. In the elastic member 46, the spacer 45 is interposed between the screw head of the fixing screw 48 and the base end portion of the elastic member 46, and then the fixing screw 48 as a fixing member is inserted into the through hole 47, and further the fixing hole 48 a. It is fixed by tightening to. The spacer 45 receives the fastening force of the fixing screw 48 and presses and supports the base end portion of the elastic member 46 against the region 33 b on the one end portion side of the base 31. The distal end side of the elastic member 46 is in line contact with the protrusion 44 of the shaft pressing member 41 disposed in the opening 35 and urges the shaft pressing member 41 in a direction of pushing the shaft pressing member 41 into the opening 35. Thereby, the shaft pressing member 41 can press the second shaft 23b with a uniform pressing force regardless of the position of the flat surface 41a. The holding force for holding the first panel 10a and the second panel 10b in an intermediate state, that is, the pressing force for engaging the second shaft 23b with the recess 34 can be adjusted by the strength of the leaf spring of the elastic member 46.

  It should be noted that the same effect can be obtained even if the protrusion 44 is formed by a single protrusion that makes point contact with an elastic member 46 formed by a leaf spring. Also, there may be a plurality of protrusions. As an example, the plurality of protrusions can be provided in a straight line in the W direction.

Next, the effect | action of the partition 1 comprised as mentioned above is demonstrated.
When the partition 1 is in the unfolded state, the first panel 10a and the second panel 10b are arranged along the direction of the arrow D1 and partitioned into a first space portion and a second space portion that are adjacent to each other. At this time, the hinge 5 is in a state indicated by a solid line in FIG. 2, that is, in a state where the engaging protrusion 15a is engaged with the engaging recess 15b, and maintains the unfolded state of the first panel 10a and the second panel 10b. ing. Further, as shown in FIG. 5, the intermediate stopper unit 6 is in a state where the second shaft 23 b is located at one end portion away from the concave portion 34 of the slide hole 32.

  Since the hinge 5 is disposed on the upper and lower edges of the first panel 10a and the second panel 10b, it is inconspicuous when viewed from either the first space portion or the second space portion. In addition, the intermediate stop unit 6 is hidden by the gap preventing member 24 and the back wall 16b of the summoning bowl 11d.

  When the first panel 10a and the second panel 10b are folded, the boundary portion between the first panel 10a and the second panel 10b is pressed in the direction of arrow D2 in FIG. As a result, the first panel 10a and the second panel 10b are rotated in the directions of arrows R1 and R2, which are folding directions, around the shaft portions of the upper runner 4a and the lower runner 4b. Then, the engagement protrusion 15a of the hinge 5 is disengaged from the engagement recess 15b, and the first panel 10a and the second panel 10b are rotated in the arrow R direction. Then, as shown in FIG. 6, the second shaft 23 b of the intermediate stopper unit 6 moves the first flat portion 32 a in the slide hole 32 from one end to the other end close to the recess 34.

  Then, as shown in FIG. 7, the second shaft 23b pressed through the shaft pressing member 41 by the elastic member 46 during the rotation is engaged with the recess 34 after passing the first flat surface portion 32a. Then, the angle θ formed by the panel surface of the first panel 10a and the panel surface of the second panel 10b is temporarily held in an intermediate state of a predetermined angle (the first panel 10a indicated by the chain line in FIG. 1B and (Refer to the second panel 10b). The predetermined angle may be an acute angle or an obtuse angle, but is 54.5 ° in this embodiment. In the process of folding the first panel 10a and the second panel 10b, the first panel 10a and the second panel 10b are moved in the direction of the arrow D1 in this intermediate state.

  At this time, the upper runner 4a and the lower runner 4b, which are the rotation centers of the first panel 10a, and the upper runner 4a and the lower runner 4b, which are the rotation centers of the second panel 10b, are the first panel 10a and the second panel 10b. Is located farther away than in the fully folded state. Therefore, no matter which position, such as the upper position, the lower position, or the middle position in the width direction, of the first panel 10a and the second panel 10b is pushed in the direction of the arrow D1, the upper runner 4a and the panels 10a and 10b It is possible to prevent any one of the lower runners 4b of 10a and 10b from proceeding in advance. Thereby, the 1st panel 10a and the 2nd panel 10b become difficult to incline with respect to an up-down direction, and can move to the arrow D1 smoothly.

  As shown in FIG. 8, when the first panel 10a and the second panel 10b in the intermediate state are moved to the front of the ends of the upper rail 3a and the lower rail 3b and further operated to push in the direction of the arrow D1, The first panel 10a and the second panel 10b are further rotated in the directions of arrows R1 and R2. Then, the second shaft 23 b of the intermediate stopper unit 6 moves away from the recess 34 and moves to the second flat surface portion 32 b located at the other end portion of the slide hole 32. Thus, the first panel 10a and the second panel 10b further move in the direction of the arrow D1 while rotating in the directions of the arrows R1 and R2, and are folded at the ends of the upper rail 3a and the lower rail 3b (FIG. 1 ( b)).

  When the first panel 10a and the second panel 10b move from the folded state to the unfolded state, they are operated in the direction opposite to the arrow D2. Then, the first panel 10a and the second panel 10b are further rotated in the directions of the opposite arrows R1 and R2. Then, the second shaft 23b of the intermediate stopper unit 6 starts to move from the second flat surface portion 32b at the other end of the slide hole 32 toward the one end, and is first engaged with the recess 34 so that the intermediate state temporarily changes. Retained. Thereafter, in the intermediate state, the first panel 10a and the second panel 10b are further rotated in directions opposite to the arrows R1 and R2. Then, the 2nd axis | shaft 23b remove | deviates from the recessed part 34, moves to the 1st plane part 32a of the slide hole 32, and reaches one end part. As a result, the first panel 10a and the second panel 10b are in the deployed state, and the hinge 5 is engaged with the engagement recess 15b in the hinge 5 and the expanded state of the first panel 10a and the second panel 10b. Hold.

The partition 1 as described above can obtain the effects listed below.
(1) The partition 1 is temporarily held in an intermediate state when the first panel 10a and the second panel 10b are moved in the direction of the arrow D1. Therefore, it is possible to prevent the first panel 10a and the second panel 10b from being inclined with respect to the vertical direction during the movement in the direction of the arrow D1. As a result, when the first panel 10a and the second panel 10b are folded, they can be smoothly moved in the direction of the arrow D1.

  (2) When the first panel 10a and the second panel 10b are folded, the hinge 5 and the intermediate stopper unit 6 that support the rotation are used. The stop unit 6 can be reduced in size. Therefore, by reducing the size of the intermediate stopper unit 6, it is possible to use a thinner member for the summoning bowl 11d, and the degree of freedom in designing the partition 1 can be increased.

  (3) The partition 1 can be made inconspicuous even when viewed from the front side and the back side by disposing the hinges 5 on the upper and lower edges of the first panel 10a and the second panel 10b. The intermediate stop unit 6 can be hidden by the gap preventing member 24 and the back wall 16b of the summoning bowl 11d. Therefore, the partition 1 can improve the design as a whole.

  (4) In the intermediate stop unit 6, the intermediate stop state can be maintained by engaging the second shaft 23 b with the recess 34 of the slide hole 32 when the first panel 10 a and the second panel 10 b are rotated. .

  (5) The intermediate stopper unit 6 can be reliably engaged with the recess 34 by constantly pressing the second shaft 23b with the shaft pressing member 41 and the elastic member 46. The holding force that temporarily holds the first panel 10 a and the second panel 10 b in the intermediate state can be adjusted by the pressing force of the elastic member 46.

  (6) Since the elastic member 46 is in line contact with the protrusion 44 of the shaft pressing member 41, the shaft pressing member 41 is guided by the guide recess 36, the guide protrusion 42, and the guide wall 43 while the second shaft 23b is moved. Irrespective of the position of the flat surface 41a, it can be pressed with a uniform pressing force.

In addition, the above partitions 1 can also be implemented by appropriately changing as follows.
As long as the shaft pressing member 41 is configured to be pressed by the elastic member 46, the protrusion 44 may be omitted.

The elastic member 46 as a pressing member that presses the second shaft 23b may be a coil spring or rubber that is arranged so as to press the shaft pressing member 41 instead of the leaf spring.
The elastic member 46 may be omitted, and the configuration of the pressing member that presses the second shaft 23b may be omitted.

  The intermediate stop portion on the inner surface of the slide hole 32 is not the concave portion 34 with respect to the first flat portion 32a and the second flat portion 32b, but two protrusions protruding with respect to the first flat portion 32a and the second flat portion 32b. It is good also as a recessed part comprised between. This is because even with such a configuration, the second shaft 23b is temporarily held in the recess between the two protrusions, and the movement of the second shaft 23b can be temporarily stopped. In this case, the second shaft 23b rides on the protrusion and moves from the concave portion to the second flat surface portion 32b or the first flat surface portion 32a.

-The intermediate | middle stop unit 6 is not limited to the structure of FIGS.
-The hinge 5 is not limited to the structure of FIG.
-The position where the upper hinge 5a is disposed may be a corner portion formed by the upper collar 11a and the summon collar 11d, and a place other than the end of the upper edge. Further, the position where the lower hinge 5b is disposed may be a corner portion formed by the lower rod 11b and the summoning rod 11d and other than the end portion of the lower edge portion. As an example, the upper hinge 5a and the lower hinge 5b may be arranged on the summing bar 11d constituting the vertical edge portion so as to be displaced from the intermediate stopper unit 6. In this case, the hinge is preferably a hidden hinge from the viewpoint of design. Further, the number of hinges arranged between the paired panels is not limited to two, that is, an upper hinge and a lower hinge, and may be three or more. In the case of providing a hinge other than the upper hinge and the lower hinge, as an example, the hinge may be further arranged in the middle of the summing bowl 11d so as not to interfere with the intermediate stopper unit 6.

The intermediate stop unit 6 may not be provided at a position corresponding to the middle rail 11f as long as the intermediate stop unit 6 is provided at any position of the summoning bar 11d.
In the partition 1, the number of panels may be 3 or more. Alternatively, two adjacent panels may be paired, and the hinge 5 and the intermediate stopper unit 6 may be disposed as members connecting the pair of panels. As an example, a pair of the first panel and the second panel, a pair of the third panel and the fourth panel, a hinge 5 between the first panel and the second panel, and between the third panel and the fourth panel. Further, an intermediate stop unit 6 may be arranged. Further, the hinge 5 and the intermediate stopper unit 6 may be arranged between the second panel and the third panel.

As the partition, a plurality of rows of upper and lower rails may be provided in parallel to each other, and panels in each row may be provided so as to be operated in a sliding manner.
In the partition, the rail may be only the upper rail that suspends and supports the panel via the upper runner by omitting the lower rail and the lower runner. Moreover, the partition provided with the upper and lower rails and the upper and lower runners may support the panel load with the lower runner, or may be supported with the upper runner suspended.

  -Each panel may be configured such that the ridges are omitted and only the panel is configured, the ridges other than the upper ridge are omitted, or the ridges other than the upper and lower ridges are omitted.
