Description

[Technical field]

[0001] The present invention relates to a privacy door to be attached to a knockdown shelf having shelves disposed between a plurality of pipe-shaped supports, and to a knockdown shelf provided with the privacy door. [Background technology]

[0002] Various types of assembly shelves in which shelves are provided between a plurality of pipe-shaped supports have been known in the past. Patent Document 1 discloses a loading shelf as an example of such an assembly shelf. This loading shelf is provided with a blind door to prevent items placed on the shelf from being seen from the outside. This blind door is provided rotatably relative to the supports of the assembly shelf via an insertion support hinge attached to the supports.

[0003] Incidentally, this insertion support hinge is configured with holes (fixed shaft hole, rotating shaft hole) for passing through shaft parts (reinforcement pillars) provided on the support pillars or the privacy door, and the privacy door is configured by attaching the privacy main body (door panel) to the inside of a frame body formed in a rectangular shape.

[0004] However, the insertion support hinge is formed so that it is arranged on the support pillar and then fastened with a bolt to fix it to the support pillar. The frame of the blind door is formed by bending a rod-shaped member multiple times, and the reinforcing pillar is formed by further bending both ends of the rod-shaped member multiple times. Therefore, the structure of the insertion support hinge and the reinforcing pillar is complicated. Furthermore, when fixing the insertion support hinge to the support pillar, it is necessary to move the insertion support hinge to a predetermined position while it is arranged on the support pillar, adjust the direction, and then fasten the insertion support hinge to the support pillar with a bolt. Therefore, the work of attaching the insertion support hinge to the support pillar is troublesome.

[0005] Therefore, there has been a demand for a blind door and an assembly shelf having the same, which have a simple structure for rotatably attaching the blind door to the support pillars of the assembly shelf and which enable the blind door to be easily attached to the support pillars.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0016] 1 to 14 show an embodiment of a privacy door according to the present invention. This privacy door is intended to prevent items placed on a shelf of an assembly shelf having shelves between multiple posts from being viewed from the outside, and in this embodiment, a privacy door to be attached to an assembly shelf having two shelves will be described as an example.

[0017] First, before describing the blind door according to the present invention, the assembly shelf will be described. As shown in Fig. 19(a) and Fig. 19(b), the assembly shelf 80 has four first to fourth support columns (support columns) 81-84 and two first and second shelf boards (shelf boards) 85, 86. Each of the first to fourth support columns 81-84 is formed in a cylindrical shape with holes (hollow) 81a-84a penetrating vertically inside, and these support columns 81-84 are formed to have the same shape as each other, that is, the same outer diameter, inner diameter, and length. Of these pillars 81-84, the first and second pillars 81, 82 are disposed on the front side in the front-rear direction perpendicular to the up-down direction, and the third and fourth pillars 83, 84 are disposed on the rear side of the first and second pillars 81, 82, and the first and second pillars 81, 82 and the third and fourth pillars 83, 84 are disposed at equal intervals in the width direction (hereinafter referred to as the "left-right direction") perpendicular to the front-rear direction. Therefore, the first to fourth pillars 81-84 are disposed at the four corners of a rectangle in a plan view.

[0018] Between these first and fourth pillars 81-84, first and second shelf boards 85, 86, which are rectangular in plan view and plate-like in side view, are attached. In this embodiment, the first shelf board 85 is attached to the upper part between the first and fourth pillars 81-84, and the second shelf board 86 is attached to the lower part between the first and fourth pillars 81-84.

[0019] A first opening 87 surrounded by the first and second pillars 81, 82 and the first shelf 85 is located above the front side of the first shelf 85, a second opening 88 surrounded by the shelves 85, 86 and the first and second pillars 81, 82 is located above the front side of the first shelf 85, and a third opening 89 surrounded by the first and second pillars 81, 82 and the second shelf 86 is located below the front side of the second shelf 86.

[0020] Next, a description will be given of the privacy door attached to the above-mentioned assembly shelf 80. The privacy door 1 of this embodiment is capable of opening and closing the first and second openings 87, 88, and opening and closing the upper side of the third opening 89, and is attached so as to be engageable with and detachable from the first support pillar 81 arranged on the front side of the assembly shelf 80.

[0021] As shown in Figures 1 to 7, the privacy door 1 is composed of a rectangular frame body 10, a privacy main body 35 for privacy attached to the inside of the frame body 10, and first and second pivotal connecting parts 40, 60 attached to the left end part of the frame body 10 in the left-right direction and connecting the frame body 10 to the first support pillar 81 so that it can be freely rotated around the axis of the first support pillar 81.

[0022] In this embodiment, the frame body 10 is formed in a rectangular shape extending in the vertical direction, and is framed in a rectangular shape by an upper horizontal frame 11, a lower horizontal frame 15, a left vertical frame 20, and a right vertical frame 25. The horizontal frames 11, 15 and the vertical frames 20, 25 are formed by extruding a metal material such as aluminum.

[0023] The upper horizontal frame 11 and the lower horizontal frame 15 are hollow frames formed to have the same shape, and are arranged in parallel to each other with the screen body 35 in between. As shown in Figs. 2, 3, and 8, the upper horizontal frame 11 has an insertion groove 12 formed in the left-right direction that opens toward the opposite side (upper side) from the lower horizontal frame 15. A positioning protrusion 48 of the first pivot connection part 40 described later is inserted into this insertion groove 12. In addition, the upper horizontal frame 11 has an arc-shaped coupling groove 13 formed in the left-right direction that opens toward the lower horizontal frame 15 side, and a bolt 41 inserted into the first pivot connection part 40 described later is screwed into this coupling groove 13, whereby the upper horizontal frame 11 and the left vertical frame 20 are fastened together and fixed, and the first pivot connection part 40 is fixed to the left vertical frame 20.

[0024] 6, the lower horizontal frame 15 is formed in the same manner as the upper horizontal frame 11, but differs from the upper horizontal frame 11 in that the insertion grooves 12 are arranged to open downward, i.e., facing in the opposite direction. Since the lower horizontal frame 15 is otherwise similar to the upper horizontal frame 11, the same reference numerals are used for the same parts as the upper horizontal frame 11, and the description thereof will be omitted.

[0025] The left vertical frame 20 and the right vertical frame 25 are hollow frames formed to have the same shape, and are arranged to extend parallel to each other and face each other in the left-right direction with the screen body 35 in between. On the opposite side (left side) of the left vertical frame 20 to the right vertical frame 25, as shown in Figs. 4, 5, 8, and 9, a fixing groove 21 that opens to the left is formed along the vertical direction (longitudinal direction), and a pair of locking protrusions 22 that protrude toward each other and extend in the vertical direction are formed on the left end of the left vertical frame 20. A gap 23 extending in the vertical direction is formed between the pair of locking protrusions 22. On the outer side (left side) of the locking protrusion 22, a planar side surface 22b (see Fig. 5) extending in the vertical direction is formed.

[0026] An insertion groove 24 extending in the vertical direction is formed on the right vertical frame 25 side (right side) of the fixing groove 21 of the left vertical frame 20, and the upper right side of the insertion groove 24 is open. The left end of the upper horizontal frame 11 is inserted into the upper part of this insertion groove 24. The fixing groove 21 and the insertion groove 24 are partitioned by an intermediate wall 29 extending in the vertical direction, and an opening 30 (see FIG. 9) that communicates between the fixing groove 21 and the insertion groove 24 and is open at the top is formed in the upper part of the intermediate wall 29. A positioning protrusion 48 of a first pivot connector 40 described later is inserted into this opening 30.

[0027] The depth of the opening 30 is approximately the same as the depth of the insertion groove 12 of the upper horizontal frame 11. The left end of the upper horizontal frame 11 inserted into the upper part of the insertion groove 24 is fixed to the left vertical frame 20 via a first pivot connecting part 40 (described later) in a state of abutting against the intermediate wall 29 located below the opening 30. A positioning protrusion 48 of the first pivot connecting part 40 (described later) is inserted into the insertion groove 12 of the upper horizontal frame 11 inserted into the upper part of the left vertical frame 20. A hole 29a (see Figures 8 and 9) penetrating in the left-right direction is formed in the intermediate wall 29 below the opening 30, and this hole 29a communicates with the coupling groove 13 formed in the upper horizontal frame 11.

[0028] An opening 30 and a hole 29a are also formed in the lower part of the left vertical frame 20. These openings 30 and holes 29a are similar to the openings 30 and holes 29a formed in the upper part of the left vertical frame 20 described above, so a description of them will be omitted.

[0029] The right vertical frame 25 has the same shape as the left vertical frame 20, but differs from the left vertical frame 20 in that the fixing groove 21 is positioned facing the opposite side (right side) from the privacy screen main body 35. In other respects, it is similar to the left vertical frame 20, so the same symbols are used for the same parts as the left vertical frame 20 and their descriptions are omitted.

[0030] 17-19, the width W1 in the left-right direction of the frame body 10 composed of the upper horizontal frame 11, lower horizontal frame 15, left vertical frame 20, and right vertical frame 25 is slightly larger than the width W2 of the first to third openings 87, 88, 89, and is smaller than the width W3 between the first and second pillars 81, 82. In addition, the height H1 of the frame body 10 is slightly smaller than the height H2 of the first and second pillars 81, 82.

[0031] The screen body 35 is formed in a rectangular shape when viewed from the front, and is attached to the upper horizontal frame 11, the lower horizontal frame 15, the left vertical frame 20, and the right vertical frame 25 so as to cover the entire opening that opens to the inside of the frame body 10. The screen body 35 is formed from a material such as fabric or a resin plate that prevents items placed on the shelves 85, 86 from being seen from the outside.

[0032] Next, the first pivot connection part 40 will be described. As shown in Fig. 8 and Fig. 10, the first pivot connection part 40 is attached to the connection part of the upper horizontal frame 11 and the left vertical frame 20 in the frame body 10. The first pivot connection part 40 is disposed on the upper ends of the upper horizontal frame 11 and the left vertical frame 20 connected to each other, and has a support arm part 42 extending toward the rear side (back side) of the frame body 10, and a shaft part 44 extending downward to be attached to the support arm part 42 and inserted into the inside from the upper end of the first support column 81 to enable rotation around the axis of the first support column 81. In this embodiment, in addition to the support arm part 42 and the shaft part 44, the first pivot connection part 40 further has a fixing protrusion part 46 extending downward from the support arm part 42 and a positioning protrusion part 48 protruding laterally from the upper side surface of the fixing protrusion part 46. The first pivot connection part 40 is integrally formed from a synthetic resin material or the like.

[0033] The support arm portion 42 is formed in a plate shape in a side view and in a rectangular shape in a plan view, the longitudinal tip of the support arm portion 42 is formed in a semicircular shape, and first and second straight line portions 42a, 42b that are perpendicular to each other are formed on the longitudinal base end side. The first straight line portion 42a is formed longer than the second straight line portion 42b, and extends at an obtuse angle θ with respect to the side wall portion 42c extending in the longitudinal direction of the support arm portion 42. Details of the obtuse angle θ will be described later. When the first rotation connecting portion 40 is attached to the frame body 10, the first straight line portion 42a is arranged so as to be aligned with the front side surface 20a of the left vertical frame 20 in the front-rear direction (see FIG. 2). Therefore, the shaft portion 44 is arranged outside the frame body 10 in the left-right direction (width direction) and on the rear side (back side) of the frame body 10. Details of the positional relationship between the shaft portion 44 and the frame body 10 will be described later.

[0034] A shaft 44 extending in a direction perpendicular to the support arm 42 is provided on the tip side of the lower surface of the support arm 42. This shaft 44 is inserted into the hole 81a (see FIG. 20(a)) of the first support column 81 from the upper end thereof. In this embodiment, the shaft 44 is formed in a cylindrical shape that can be fitted into the hole 81a of the first support column 81 so as to be rotatable about its axis. Inside the shaft 44, a hole 44a extending in the axial direction is formed.

[0035] 2, the support arm portion 42 is inclined at the obtuse angle θ with respect to the first straight portion 42a so that the shaft portion 44 is disposed outside and spaced rearward from the side surface 22b of the left end portion of the left vertical frame 20. Therefore, when the frame body 10 is viewed from the front, the shaft portion 44 is disposed in a positional relationship in which a part of the shaft portion 44 overlaps with the frame body 10. Therefore, when the frame body 10 is viewed from the front, no gap is formed between the side surface 22b of the left end portion of the left vertical frame 20 and the first support pillar 81 into which the shaft portion 44 is inserted, so that when the blind door 1 is closed on the first and second openings 87, 88 of the assembly shelf 80, the risk of the interior of the assembly shelf 80 being viewed from between the left end portion of the left vertical frame 20 and the first support pillar 81 can be prevented.

[0036] As shown in Figs. 8 and 10, a fixing protrusion 46 is formed on the lower surface of the support arm 42 at the end opposite to the shaft 44 in the longitudinal direction of the support arm 42, extending in a direction perpendicular to the support arm 42. The fixing protrusion 46 is formed in a rectangular parallelepiped shape having a size that allows it to be inserted into the fixing groove 21 of the left vertical frame 20, and the short-side side of the fixing protrusion 46 extends along the first straight portion 42a, while the long-side side of the fixing protrusion 46 extends parallel to the first straight portion 42a. In this embodiment, the length L2 of the fixing protrusion 46 is longer than the short-side length L1 of the upper horizontal frame 11 (see Fig. 3) and is the same as the length L4 of the shaft 44. An insertion hole 46a is provided on the tip side of the fixing protrusion 46 in the protruding direction, through which the bolt 41 is inserted. The insertion hole 46a is located at a position that communicates with the hole portion 29a provided in the intermediate wall 29 of the left vertical frame 20 and the connecting groove 13 of the upper horizontal frame 11 when the support arm portion 42 is abutted against the upper ends of the upper horizontal frame 11 and the left vertical frame 20.

[0037] Therefore, when the fixing protrusion 46 is inserted into the fixing groove 21 of the left vertical frame 20 and the support arm portion 42 is abutted against the upper ends of the upper horizontal frame 11 and the left vertical frame 20, the insertion hole 46a communicates with the coupling groove 13 via the hole portion 29a. Then, by passing the bolt 41 through the insertion hole 46a and rotating it, the bolt 41 is screwed into the coupling groove 13, and the first pivot connecting portion 40 is fixed to the left vertical frame 20 in a state in which the upper horizontal frame 11 and the left vertical frame 20 are fastened together. In addition, since the fixing protrusion 46 is fastened by the bolt 41 in a state in which it abuts against the intermediate wall 29 of the left vertical frame 20, the first pivot connecting portion 40 can be fixed in a state in which it is positioned in the left-right direction of the frame body 10.

[0038] A positioning protrusion 48 is formed on the side surface 46b of the fixing protrusion 46 facing the second straight portion 42b. In this embodiment, the positioning protrusion 48 is formed in a rectangular parallelepiped shape that protrudes from the side surface 46b of the fixing protrusion 46 and has an upper end connected to the lower surface of the support arm portion 42. The positioning protrusion 48 is disposed within the width of the short side of the fixing protrusion 46, and the width W4 of the short side of the positioning protrusion 48 is slightly narrower than the width W5 (see FIG. 3) of the insertion groove 12 of the upper horizontal frame 11. Therefore, by inserting the positioning protrusion 48 into the insertion groove 12 of the upper horizontal frame 11, the first pivot connection portion 40 can be positioned in the front-rear direction relative to the frame body 10 (left vertical frame 20). The protruding length L3 of the positioning protrusion 48 from the support arm portion 42 is approximately the same as the depth of the insertion groove 12.

[0039] Incidentally, the right end portion in the left-right direction (longitudinal direction) of the upper horizontal frame 11 and the upper end portion of the right vertical frame 25 are connected via an end cap 27, as shown in Fig. 8. The end cap 27 has the same configuration as the first pivotal connecting part 40, except that the shaft portion 44 is removed from the first pivotal connecting part 40 and the length of the support arm portion 42 is shortened. For this reason, in the end cap 27, the same parts as those in the first pivotal connecting part 40 are denoted by the same reference numerals and their explanations are omitted.

[0040] By inserting the fixing protrusion 46 of the end cap 27 into the fixing groove 21 of the right vertical frame 25 and the positioning protrusion 48 into the insertion groove 12 of the upper horizontal frame 11 and abutting the support arm portion 42 against the upper ends of the upper horizontal frame 11 and the right vertical frame 25, and rotating the bolt 41 inserted into the insertion hole 46a, the bolt 41 is screwed into the connecting groove 13, and the end cap 27 is fixed to the right vertical frame 25 with the upper horizontal frame 11 and the right vertical frame 25 tightened together.

[0041] 1, the left end of the lower horizontal frame 15 and the lower end of the left vertical frame 20, and the right end of the lower horizontal frame 15 and the lower end of the right vertical frame 25 are connected via the aforementioned end caps 27. These connections are similar to the connection between the right end of the upper horizontal frame 11 and the upper end of the right vertical frame 25, and therefore a description thereof will be omitted.

[0042] Next, the second rotational connecting part 60 will be described. As shown in Figures 11, 12 and 17, the second rotational connecting part 60 is provided at a position lower than the first rotational connecting part 40 on the left vertical frame 20. In this embodiment, the second rotational connecting part 60 is provided at the lower part of the left vertical frame 20. The second rotational connecting part 60 has an engagement recess 63 for being rotatably attached to the outer circumferential surface of the first support pillar 81 by being releasably engaged with the outer circumferential surface of the first support pillar 81.

[0043] The engagement recess 63 has a support part 62 attached to the left vertical frame 20, and a pair of first and second arm parts 63a, 63b formed on the support part 62 and arranged opposite each other with a gap between them, and on the inside of these arm parts 63a, 63b, a curved surface 63c including a circular arc surface 63c1 for fitting with the outer peripheral surface of the first support post 81 is formed. Also, between the tip parts of these arm parts 63a, 63b, an opening 63d is formed to allow the first support post 81 to be inserted and removed.

[0044] The support part 62 is plate-shaped in plan view and is formed into a rectangular shape extending in the vertical direction in front view. At the end of the support part 62 on the left vertical frame 20 side, a step part 65 that protrudes toward the left vertical frame 20 side extends in the vertical direction. In this embodiment, the step part 65 is formed into a rectangular parallelepiped shape extending in the vertical direction, and the width of the step part 65 in the short side direction is large enough to be inserted into the gap 23 (see FIG. 4) between the pair of locking protrusions 22 of the left vertical frame 20. In addition, at the end of the support part 62 on the left vertical frame 20 side, two holes 62a for inserting the bolts 67 are formed with a gap between them in the vertical direction. In this embodiment, the holes 62a also penetrate into the step part 62a.

[0045] A fastening member 68 is formed on the end face on the tip side of the step portion 65 for fixing the second rotation connecting portion 60 to the left vertical frame 20 via a bolt 67 inserted into the hole portion 62a. The fastening member 68 is formed slightly smaller than the fixing groove 21 and has a width larger than the gap 23 between the pair of locking protrusions 22, 22, and is movable relative to the fixing groove 21. The fastening member 68 is inserted into the fixing groove 21 of the left vertical frame 20 with the step portion 65 inserted into the gap 23 between the pair of locking protrusions 22, 22, and the end face of the fastening member 68 on the support portion 62 side faces the pair of locking protrusions 22, 22.

[0046] In this state, when the bolt 67 is rotated, the tip of the shaft of the bolt 67 abuts against the intermediate wall 29, and when the bolt 67 is further rotated, the fastening member 68 moves toward the pair of locking protrusions 22, 22 and abuts against these locking protrusions 22, 22 while being pressed against them. This allows the second pivotal connecting part 60 to be fixed to the left vertical frame 20. Furthermore, since the fastening member 68 is movable in the up-down direction (longitudinal direction) relative to the fixing groove 21 of the left vertical frame 20, the fastening member 68 can be fastened to any position in the longitudinal direction of the left vertical frame 20. This allows the second pivotal connecting part 60 to be fixed to any position in the longitudinal direction of the left vertical frame 20.

[0047] 6, 11 and 12, the first and second arm portions 63a, 63b of the engagement recess 63 are disposed opposite each other with a gap in the left-right direction and extend toward the rear side of the frame body 10, and the base ends of these arm portions 63a, 63b on the support portion 62 side are connected to each other and connected to the support portion 62. The first arm portion 63a is curved concavely toward the left vertical frame 20 in the direction protruding from the tip of the support portion 62, and the second arm portion 63b is curved concavely toward the side away from the left vertical frame 20 in the direction protruding from the tip of the support portion 62.

[0048] In this embodiment, the entire curved surface 63c formed on the inner surface of the arm portions 63a and 63b is formed into an arc surface 63c1. The circumferential length of each of the arm portions 63a and 63b from the support portion 62 is slightly longer for the second arm portion 63b than for the first arm portion 63a, and the circumferential length of the curved surface 63c is greater than half the entire circumference of the first support 81. That is, the angle θ2 formed by the line segments intersecting the central axis J2 extending along the longitudinal direction (up-down direction) of the left vertical frame 20 from the tip portions of the arm portions 63a and 63b is greater than 180 degrees toward the curved surface 63c (see FIG. 12). The pair of arms 63a, 63b can be elastically deformed in a direction in which the curved surface 63c expands and contracts from the state (initial state) of the pair of arms 63a, 63b when the angle between the tip of each of the arms 63a, 63b and the center S2 is θ. In addition, the opening width d1 of the opening 63d that opens between the tip of the arms 63a, 63b is smaller than the diameter d0 of the first support 81.

[0049] Therefore, when the first support 81 is inserted through the opening 63d, the first and second arm portions 63a, 63b elastically deform radially outward from their initial states, allowing the first support 81 to engage with the inside of these arm portions 63a, 63b. At this time, the first and second arm portions 63a, 63b engage with the first support 81 in a fitted state in which the arcuate surface 63c1 is in surface contact with the outer circumferential surface of the first support 81, and are capable of rotating around the axis of the first support 81.

[0050] Furthermore, when the first and second arm portions 63a, 63b are to be engaged with and disengaged from the first support pillar 81, the first and second arm portions 63a, 63b are pulled in a direction away from the first support pillar 81, whereby the arm portions 63a, 63b are elastically deformed in a direction to widen, thereby enlarging the opening 63d, and the first support pillar 81 can be disengaged from between the arm portions 63a, 63b. In this way, when the first and second arm portions 63a, 63b are to be engaged with and disengaged from the first support pillar 81, it is necessary to elastically deform the arm portions 63a, 63b in a direction to widen, so that the risk of the first and second arm portions 63a, 63b being easily disengaged from the first support pillar 81 can be prevented.

[0051] 4, the center S2 of the arc surface 63c1 is disposed on the central axis J1 of the shaft portion 44 of the first pivot connecting portion 40. Therefore, in a state in which the privacy door 1 is engaged with the assembly shelf 80 via the first and second pivot connecting portions 40, 60, the privacy door 1 can be smoothly pivoted.

[0052] Next, the locking portion 70 provided on the right vertical frame 25 will be described. As shown in Figures 2, 13, 14, and 18, the locking portion 70 is for releasably locking the privacy door 1 to the second support pillar 82. Since the locking portion 70 is formed in the same manner as the second pivotal connecting portion 60 described above, the same reference numerals will be used to designate the same parts as the second pivotal connecting portion 60, and their description will be omitted. The points that differ from the second pivotal connecting portion 60 will be described.

[0053] The locking portion 70 has a locking recess 71 for detachably locking to the second support 82 adjacent to the first support 81. The locking recess 71 has a curved surface 63c including an arcuate surface 63c1 for fitting with the outer circumferential surface of the second support 82. In this embodiment, the first and second arm portions 63a, 63b of the locking recess 71 are disposed on the rear side (back side) of the right vertical frame 25 and open toward the rear, and the center S3 of the arcuate surface 63c1 of the locking recess 71 is disposed on the axis A1 that passes through the center S1 of the shaft portion 44 and extends along the width direction of the frame body 10 (see FIG. 2).

[0054] Moreover, the first and second arm portions 63a, 63b of the locking recess 71 are disposed at a position outside (to the right) and rearward of the side surface 22b at the right end of the right vertical frame 25. That is, when the frame body 10 is viewed from the front, the first and second arm portions 63a, 63b are disposed so that a portion of these arm portions 63a, 63b overlaps with the frame body 10. Therefore, when the frame body 10 is viewed from the front, no gap is formed between the side surface 22b at the right end of the right vertical frame 25 and the second support pillar 82 to which the locking recess 71 is locked, so that when the blind door 1 is in a state in which the first and second openings 87, 88 of the assembly shelf 80 are closed, the risk of the interior of the assembly shelf 80 being viewed from between the side surface 22b of the right vertical frame 25 and the second support pillar 82 can be prevented.

[0055] 7 and 13, the locking portion 70 is attached to the vertical middle portion of the right vertical frame 25. The support portion 62 of the locking portion 70 extends from the base end of the locking recess 71 to both sides in the vertical direction along the side surface 22b of the right end portion of the right vertical frame 25, and has holes 62a on both longitudinal sides of the support portion 62.

[0056] When the locking portion 70 configured in this manner is to be locked to the second support 82, as shown in Fig. 18, the blind door 1 is rotated around the axis of the first support 81 via the first and second pivot connectors 40, 60. Then, the locking portion 70 can be locked to the second support 82 by inserting the second support 82 from the opening 63d between the first and second arm portions 63a, 63b of the locking recess 71. On the other hand, when the first and second arm portions 63a, 63b are to be released from the second support 82, the locking portion 70 is pulled forward relative to the second support 82 via the gripping portion 72 described later.

[0057] Incidentally, the locking recess 71 of the locking portion 70 is formed in the same manner as the engagement recess 63 of the second pivot connection portion 60, so that the first and second arm portions 63a, 63b are elastically deformable. For this reason, when the first and second arm portions 63a, 63b are to be engaged with and disengaged from the second support 82, it is necessary to elastically deform these arm portions 63a, 63b in the direction of expanding, so that unless a pulling operation is performed on the locking recess 71, the state in which the locking portion 70 is engaged with the second support 82 is maintained, and there is no risk of the privacy door 1 opening by itself.

[0058] 14(a) and 14(b), the fastening member 68 can be inserted into the fixing groove 21 of the right vertical frame 25 and the bolt 67 can be rotated to fix the locking portion 70 to the right vertical frame 25, and the fastening member 68 can be moved in the up-down direction (longitudinal direction) relative to the fixing groove 21 of the right vertical frame 25. Therefore, by fastening the fastening member 68 to any position in the up-down direction of the right vertical frame 25, the locking portion 70 can be fixed to any position in the up-down direction of the right vertical frame 25.

[0059] The locking portion 70 thus configured is provided with a gripping portion 72. In this embodiment, the locking portion 70 and the gripping portion 72 are integrally formed from, for example, synthetic resin.

[0060] As shown in Figs. 6 and 13, the gripping portion 72 is formed so as to be connected to the support portion 62 of the locking portion 70, and is formed in a triangular prism shape disposed opposite the front side surface 25a of the right vertical frame 25 and extending in the vertical direction (longitudinal direction) along the right vertical frame 25. The right end of the gripping portion 72 is open to form a hollow space 73, and the space 73 is surrounded by a bottom plate 74 along the side surface 25a of the right vertical frame 25, a pair of side plates 75, 76 standing from both ends of the bottom plate 74, and a curved top plate 77 installed between the pair of side plates 75, 76. Since the gripping portion 72 extends symmetrically above and below the locking portion 70, when the top plate 77 is pulled by a finger or the like inserted into the space 73, the operation acts directly on the locking portion 70, and therefore the locking operation and the unlocking operation of the locking portion 70 to the second support 82 can be easily performed.

[0061] Furthermore, the fastening member 68 formed on the engaging portion 70 can be fastened to any position in the vertical direction (longitudinal direction) of the right vertical frame 25, so that the gripping portion 72 can be fixed to any position in the vertical direction of the right vertical frame 25.

[0062] Next, a case where the blind door 1 is attached to the assembly shelf 80 will be described. First, as shown in FIG. 15, the pair of first and second arm parts 63a, 63b of the second pivot joint part 60 of the blind door 1 are arranged facing each other toward the first support column 81 side shown by the two-dot chain line, and the shaft part 44 of the first pivot joint part 40 is moved above the first support column 81 shown by the two-dot chain line. Then, the blind door 1 is moved so that the first and second arm parts 63a, 63b move closer to the first support column 81 side, and the first support column 81 is engaged between the first and second arm parts 63a, 63b. Then, as shown in FIG. 16, the blind door 1 is moved downward to insert the shaft part 44 from the upper end of the first support column 81 into the hole part 81a. At this time, the first and second arm parts 63a, 63b move toward the lower end side of the first support column 81 while sliding on the outer circumferential surface of the first support column 81. Then, when the support arm portion 42 of the first pivot connection portion 40 comes into contact with the upper end of the first support pillar 81, the operation of attaching the privacy door 1 to the first support pillar 81 of the assembly shelf 80 is completed.

[0063] On the other hand, when removing the privacy door 1 attached to the first support 81 of the assembly shelf 80, the above-mentioned operations can be reversed. That is, the privacy door 1 is moved upward relative to the left vertical frame 20, and the shaft portion 44 is removed from the hole portion 81a of the first support 81. At this time, the first and second arm portions 63a, 63b move toward the upper end of the first support 81 while sliding on the outer circumferential surface of the first support 81. Then, the privacy door 1 is moved radially outward from the first support 81, whereby the first and second arm portions 63a, 63b are disengaged from the first support 81, and the operation of removing the privacy door 1 is completed.

[0064] Thus, the main components of the privacy door 1 according to this embodiment are the shaft 44 and the first and second arm portions 63a, 63b for rotatably engaging the privacy door 1 with the first support 81. Therefore, the structure of the shaft 44 and the first and second arm portions 63a, 63b is simple, and the privacy door 1 can be attached to the assembly shelf 80 simply by inserting the shaft 44 into the hole 81a of the first support 81 and engaging the first and second arm portions 63a, 63b with the first support 81. Therefore, it is possible to provide a privacy door 1 and an assembly shelf 80 including the privacy door 1, which have a simple structure for rotatably attaching the privacy door 1 to the first support 81 and can easily attach the privacy door 1 to the first support 81.

[0065] In the embodiment described above, the first and second pivot connectors 40, 60 are provided on the left vertical frame 20 of the frame body 10, but this is not limited thereto, and the first and second pivot connectors 40, 60 may be provided on the right vertical frame 25 of the frame body 10. In this case, the locking portion 70 is provided on the left vertical frame 20 of the frame body 10. [Explanation of symbols]
