Description

Technical Field

[0001] This invention relates to a guide device for a push-in door. Background Technology

[0002] In furniture and the like, there are known structures in which a door is pushed deep into a housing from its open position along the side wall of the housing and thus housed within it. The device for guiding this push-in door, as disclosed in Patent Document 1 described later, includes: upper and lower guide rails fixed to the inner surface of the side wall of the housing and extending horizontally in the front-back direction; sliders slidably supported on these guide rails in the front-back direction; a linkage frame extending vertically and connected to the upper and lower sliders; and upper and lower hinge mechanisms provided in the linkage frame to support the door so that it can rotate.

[0003] Furthermore, the door guiding device in Patent Document 1, which maintains the door in an upright position to ensure the door's rotation axis is perpendicular, comprises two vertical tracks (front and rear) and a linkage mechanism. The front vertical track is fixed to a linkage frame, and the rear vertical track is fixed to the inner side wall of the housing. The linkage mechanism, for example, is formed into an X shape by rotatably connecting the central parts of the first and second linkages. The rear ends of the two linkages are supported on the rear vertical track via rollers. The front end of the first linkage is not movable but rotatably supported on the front vertical track, and the front end of the second linkage is supported on the front vertical track via rollers.

[0004] When the door is pushed in from the open position, the upper and lower sliders slide along the guide rails, while the linkage frame moves inward toward the housing. During this process, the linkage mechanism is folded.

[0007] Patent Document 1: Japanese Patent Application Publication No. 6-58040 Summary of the Invention

[0008] The door guide device in Patent Document 1 is large and expensive because it has two vertical tracks and a linkage mechanism.

[0009] Technical solutions for solving the problem

[0010] The present invention was made to solve the above-mentioned problems. The present invention is a door guiding device that supports a door for opening and closing an opening of a storage body, allowing it to rotate about a rotation axis extending in the vertical direction, and guides the door inward along the side wall of the storage body from the open position. Its characteristic feature is that it comprises:

[0011] Multiple guide rails, extending horizontally in the front-back direction, are fixed vertically and horizontally to the sidewalls of the storage body; multiple sliders, each slidably supported on the multiple guide rails in the front-back direction; a vertical frame connected to the multiple sliders; and a hinge mechanism disposed on the sliders or the vertical frame, supporting the door so that it can rotate about a rotation axis.

[0012] A support unit is provided between at least one of the sliders and the vertical frame, the support unit being used to maintain the angle between the slider and the vertical frame at an angle perpendicular to the rotation axis.

[0013] With the above structure, the door can be stably supported in an upright position by the support unit set between the vertical frame and the slider. In addition, since a large linkage mechanism can be omitted, low cost can be achieved.

[0014] Preferably, the support unit has an adjustment unit that adjusts the angle between the slider and the vertical frame to make the rotation axis vertical and correct the door to an upright position.

[0015] With the above structure, after the door is placed in the storage body via the door guide device, the door can be corrected to an upright position by the adjustment unit.

[0016] Preferably, the support unit includes at least one support component, and the adjustment unit is configured to adjust the connection position between the at least one support component and the slider or vertical frame.

[0017] Using the above structure, the posture of the door can be corrected relatively easily by adjusting the connection position.

[0018] Preferably, the adjusting unit has: an elongated hole formed in the slider or the vertical frame; and a locking shaft portion disposed in the at least one support member and passing through the elongated hole, wherein a plurality of locking recesses are formed at the edge of the elongated hole, and the locking shaft portion engages selectively with any one of the plurality of locking recesses.

[0019] Using the above structure, the connection position can be easily adjusted.

[0020] Preferably, the at least one support member is composed of a single support member, which is connected to the slider via a first end and to the vertical frame via a second end.

[0021] The above structure can further simplify the structure of the support unit.

[0022] Preferably, the line connecting the first end and the second end of the support member is inclined. This structure allows the door to be maintained in an upright position more stably.

[0023] In one embodiment, the first end of the support member is connected to the slider at a position separated from the vertical frame.

[0024] With the above structure, the distance between the connection between the slider and the vertical frame and the connection between the support component and the slider can be extended, so even if the door is heavy, the support component can stably maintain the door's upright posture.

[0025] In other configurations, the support member overlaps with the vertical frame, and the first end is connected to the slider without being constrained by the vertical frame.

[0026] By adopting the above structure, the length of the slider can be shortened, thus reducing the amount of protrusion of the door from the storage body when the door is pushed into the storage body.

[0027] The support unit can also be configured as follows: The at least one support member includes a first support member and a second support member. The first support member extends along the length of the vertical frame. The vertical frame is rotatably connected to the slider at a first connection point. The first support member is rotatably connected to the slider at a second connection point separated from the first connection point in the longitudinal direction. One end of the second support member is rotatably connected to the first support member at a third connection point separated from the second connection point in the vertical direction. The adjustment unit includes the elongated hole formed in the vertical frame and the engaging shaft portion disposed at the other end of the second support member. The engaging shaft portion is provided as a fourth connection point connecting the second support member and the vertical frame.

[0028] In one embodiment of the aforementioned support unit, the first support member and the second support member overlap with the vertical frame. In other embodiments, the first support member is disposed separately from the vertical frame in the front-rear direction, and the second support member is positioned between the first support member and the vertical frame.

[0029] In another embodiment, the support unit includes a support member connected to the slider via a first end and to the vertical frame via a second end, and the adjustment unit is configured to adjust the length of the support member.

[0030] By using the above structure, the posture of the door can be corrected by adjusting the length of the supporting components.

[0031] More preferably, the support component is made of a pull stud. This structure allows for easy correction of the door's posture through simple operation.

[0032] Another aspect of the invention is a door guiding device that supports a door for opening and closing a storage body so as to rotate about a rotation axis extending in the vertical direction, and guides the door inward along the side wall of the storage body from the open position, characterized by comprising:

[0033] At least one guide rail extending horizontally in the front-rear direction and fixed to the side wall of the storage body; at least one slider slidably supported on the at least one guide rail in the front-rear direction; a vertical frame connected to the slider; and a hinge mechanism supporting the door so that it can rotate about the rotation axis.

[0034] A support unit is provided between the slider and the vertical frame, which is used to maintain the angle between the slider and the vertical frame at an angle perpendicular to the rotation axis.

[0084] <First Implementation Method>

[0085] See Figure 1 for the following. Figure 4The first embodiment of the present invention will be described. The furniture shown in FIG1 includes a housing 1 (storage body) and a push-in door 2. In the following description, the opening 1a side of the housing 1 is referred to as the front side, and the inner side of the housing 1 is referred to as the rear side. In the housing 1, for example, a partition wall 1c is formed parallel to the right side wall 1b, and a door storage space 1d is formed between these right side walls 1b and the partition wall 1c. As will be described later, at the entrance of the door storage space 1d, a roller 3 is disposed separately from the inner surface of the side wall 1b to guide the side of the door 2 when it is pushed in or pulled out. It should be noted that the partition wall 1c can be omitted.

[0086] like Figure 2 As shown, the door guide device 5 has two (or more) guide rails 10 fixed to the inner surface of the side wall 1b of the housing 1. These guide rails 10 extend horizontally in the front-rear direction and are vertically separated from each other. Each guide rail 10 supports a slider 20, which is capable of sliding in the longitudinal direction (front-rear direction) of the guide rail 10. In this embodiment, the slider 20 is supported on the guide rail 10 via a ball retainer 25, but it may also be supported directly on the guide rail 10 without the ball retainer 25.

[0087] The door guide device 5 includes an L-shaped linkage frame 30 (vertical frame) for linking the upper and lower sliders 20. The linkage frame 30 extends substantially vertically, with its upper and lower ends connected to the rear portions of the upper and lower sliders 20, respectively. More specifically, as... Figure 4 As shown, two threaded holes 21 are formed separately at the rear of the lower slider 20, and two round holes 31 are formed separately at the lower end of the linkage frame 30. The lower end of the linkage frame 30 is connected to the rear of the lower slider 20 by screwing screws 35 through these round holes 31 into the threaded holes 21 of the slider 20. The upper end of the linkage frame 30 is similarly connected to the rear of the upper slider 20.

[0088] The upper and lower sliders 20 have connecting brackets 40, 40' made of flat plates at their front. More specifically, as... Figure 4 As shown, two threaded holes 22 are formed separately at the front of the main body of the lower slider 20. The lower connecting bracket 40 is trapezoidal, with two separate circular holes 41 formed at its middle height. The connecting bracket 40 is fixed to the front of the main body of the slider 20 by screwing screws 45 through these circular holes 41 into the threaded holes 22 of the slider 20. This connecting bracket 40 is provided as part of the slider 20. The upper connecting bracket 40' is rectangular and is fixed to the front of the upper slider 20 in the same manner as described above.

[0089] Hinges 50 are provided on the upper and lower connecting brackets 40 and 40' respectively. The hinge mechanism 50 of this embodiment includes: a housing-side hinge body 51 fixed to the connecting brackets 40 and 40'; a door-side hinge body 52 fixed to the inner surface near the right side edge of the door 2; and a plurality of connecting rods 53 connecting these hinge bodies 51 and 52. The hinge mechanism 50 supports the door 2 so that it can rotate along four vertically extending axes (in... Figure 3 The diagram is roughly shown with a rotation axis L as the center of rotation. It should be noted that these rotation axes move as the door 2 is opened and closed.

[0090] like Figure 2 , Figure 3 As shown, the door guide device 5 has a pull stud 60 (support component, support unit) at its lower part. Figure 4 As shown, the pull stud 60 has a cylindrical operating cylinder 61 and two screws 62 and 63 extending in a straight line and threadedly engaged with the operating cylinder 61. Internal threads with opposing threads are formed on the inner circumference of both ends of the operating cylinder 61, and the male threads of the screws 62 and 63 are threaded into these internal threads. These male threads of the screws 62 and 63 and the operating cylinder 61 constitute an adjusting unit 60A for adjusting the length of the pull stud 60. The screws 62 and 63 have ring portions 62a and 63a at their outer ends. When the operating cylinder 61 is rotated in one direction, the pull stud 60 extends, and the ring portions 62a and 63a move apart; when rotated in the other direction, the pull stud 60 retracts, and the ring portions 62a and 63a move closer together.

[0091] One end of the pull stud 60 has a ring 62a that is rotatably connected to the upper end of the lower connecting bracket 40. Specifically, a collar 65 is housed within the ring 62a, and washers 66 and shims 67 are arranged on both sides of the ring 62a. A screw 68, passing through these collars 65, washers 66, and shims 67, is passed through a circular hole 42 formed in the upper end of the connecting bracket 40, and secured using the screw 68 and a nut 69 disposed on the back side of the connecting bracket 40. Thus, the ring 62a is rotatably connected to the upper end of the connecting bracket 40. Figure 3 In the figure, the connecting part (first connecting part; first end) is marked with reference numeral P1.

[0092] The ring 63a at the other end of the pull stud 60 is rotatably connected to the linkage frame 30 at a predetermined distance above the lower slider 20. Specifically, like ring 62a, ring 63a is rotatably connected to the linkage frame 30 by passing a screw 68 through a circular hole 32 formed in the linkage frame 30, and fastening it with the screw 68 and a nut 69 disposed on the back side of the linkage frame 30. Figure 3In the figure, the connecting part (second connecting part; second end) is marked with reference numeral P2.

[0093] The function of the door guide device 5, which forms the above-described structure, will be explained. When the door 2 is in the closed position, the upper and lower sliders 20 and the hinge mechanism 50 are located near the opening 1a of the housing 1. By rotating the door 2 90°, the door 2 reaches... Figure 1A The door 2 is pushed further in from this open position. When the door 2 is pushed in further from this open position, the upper and lower hinge mechanisms 50, the upper and lower sliders 20, and the linkage frame 30 of the door guide device 5 move inward as a whole, guiding the door 2 to the open position. Figure 1B The storage location is shown. As a result, most of door 2 is stored in door storage space 1d.

[0094] With the opening 1a of the housing 1 closed, the door 2 is pulled out and returned to its original position by the guidance of the door guide device 5. Figure 1A The door is moved to the 90° open position, which in turn causes door 2 to rotate to the closed position.

[0095] The door guide device 5 is designed to make the rotation axis L perpendicular, supporting the door 2 so that it can rotate in an upright position around the rotation axis L. However, in reality, due to the clearance between the guide rail 10 and the slider 20, and the clearance between the screw 35 and the round hole 31 in the connection between the slider 20 and the linkage frame 30, the door 2 will... Figure 2 , Figure 3 As shown by the imaginary line, the object leans forward due to its own weight and cannot maintain the perpendicularity of the rotation axis L. Therefore, this hinders the opening and closing function.

[0096] In this embodiment, by adjusting the pull stud 60, the forward tilting posture of the door 2 can be corrected to an upright posture, making the rotation axis L perpendicular. A detailed explanation follows.

[0097] The pull stud 60 is designed to be the length of the slider 20 at a right angle to the linkage frame 30, and its two ends are connected to the linkage frame 30 and the connecting bracket 40 as described above. The screws 35 connecting the upper and lower slider 20 and the linkage frame 30 are loosened beforehand. In this state, the door 2 tilts forward due to its own weight (in... Figure 2 , Figure 3 (Illustrated by an imaginary line), the rotation axis L is tilted. The length of the pull stud 60 is adjusted by rotating the operating cylinder 61 of the pull stud 60, thereby correcting the posture of the door 2. In this embodiment, the angle θ between the slider 20 and the linkage frame 30 is adjusted by extending the pull stud 60 (see reference). Figure 3 ),like Figure 2 , Figure 3 As shown, door 2 is corrected to an upright position (in Figure 2 , Figure 3(Represented by solid lines in the middle), so that the axis of rotation L is essentially returned to perpendicular.

[0098] As described above, the posture correction of the door 2 can be easily performed simply by rotating the operating cylinder 61 of the pull stud 60. After the correction operation is completed, tighten the screw 35. It should be noted that if there is play between the screw 45 and the round hole 41, the screw 45 should be loosened before performing the correction operation using the pull stud 60 and tightened after the correction operation is completed.

[0099] After the posture correction of the door 2 described above, the angle θ between the slider 20 and the linkage frame 30 is maintained at an angle that is substantially perpendicular to the rotation axis L and the door 2 is in an upright position by the pull stud 60. Therefore, the door 2 can be opened and closed stably for a long period of time.

[0100] By using the pull stud 60, the complex and large linkage mechanism of existing door guide devices can be omitted, and the above-mentioned posture correction operation can be performed simply.

[0101] In this embodiment, since the connecting portions P1 and P2 of the pull stud 60 can be fully separated in the front-to-back direction, the tilt angle of the pull stud 60 can be increased. Therefore, even if the door 2 is heavy, the aforementioned angle-maintaining function can be reliably performed.

[0102] <Second Implementation Method>

[0103] Next, other embodiments of the present invention will be described. In these embodiments, the same reference numerals are used to denote the structural parts corresponding to the first embodiment, and detailed descriptions thereof are omitted.

[0104] exist Figures 5-7 In the second embodiment shown, instead of the pull stud 60 of the first embodiment, a support member 70 (support unit) made of a rigid body, such as an elongated plate, is used. One end of the support member 70 is connected to the upper end of the connecting bracket 40 as described later, and the other end uses the same washers 66, shims 67, screws 68 (fasteners), and nuts 69 (see reference) as in the first embodiment. Figure 4 It is rotatably connected to the linkage frame 30.

[0105] Circular holes (not shown) are formed at both ends of the support member 70, through which screws 68 pass. Figure 6 , Figure 7 As shown, an elongated hole 43 extending in the front-rear direction is formed at the upper end of the connecting bracket 40 instead of the round hole 42 in the first embodiment, and the shaft portion 68a (engaging shaft portion) of the screw 68 passes through this elongated hole 43. A plurality of, for example, four engaging recesses 43a are formed at the lower edge of the elongated hole 43.

[0106] In the second embodiment, before posture correction, the screw 35 connecting the upper and lower sliders 20 and the linkage frame 30 is loosened. During posture correction, the door 2 is held so that its rotation axis is perpendicular, making the door 2 upright. In this posture, the shaft portion 68a of the screw 68 of the connecting part P1 is selectively engaged with one of the four engaging recesses 43a. In this way, the angle between the slider 20 and the linkage frame 30 is adjusted, and the adjusted angle is maintained by the support member 70. After the correction operation is completed, the screw 35 is tightened.

[0107] As can be seen from the above description, the adjustment unit 70A for correcting the posture of the door 2 is constructed through the elongated hole 43 with the engaging recess 43a and the shaft portion 68a with the screw 68. In this embodiment, since the support member 70 is constructed from a single rigid body, the support member 70 can be further simplified, and cost reduction can be achieved. Other functions are the same as in the first embodiment.

[0108] In the second embodiment, one end of the support member 70 may be rotatably connected to the connecting bracket 40, and the same adjustment unit as described above may be provided at the connecting portion P2. In this case, an elongated hole is formed in the linkage frame 30, and a plurality of engaging recesses are formed at the upper edge of the elongated hole.

[0109] <Third Implementation Method>

[0110] exist Figure 8 , Figure 9 In the third embodiment shown, the pull stud 60 is used in the same way as in the first embodiment. In this embodiment, the length of the upper and lower sliders 20 in the front-to-back direction is shorter than that in the first embodiment.

[0111] The linkage frame 30 is slightly wider than in the first embodiment, connecting to the upper and lower sliders 20 in a manner that covers approximately the entire length of the slider 20. The linkage frame 30 protrudes further downward from its connection with the lower slider 20, and its protruding end is connected to the housing-side hinge body 51 of the lower hinge mechanism 50. Although not shown, the linkage frame 30 also protrudes further upward from its connection with the upper slider 20, and its protruding end is connected to the housing-side hinge body 51 of the upper hinge mechanism 50.

[0112] On the linkage frame 30, opposite to the lower slider 20, a pull stud 60 (support member) and a connecting bracket 80 are arranged in an overlapping manner. A clearance hole 81 consisting of a large-diameter circular hole is formed in the center of the lower part of the connecting bracket 80, and circular holes 82 are formed on both sides thereon.

[0113] In the linkage frame 30, a circular hole 31 is formed at the position corresponding to the clearance hole 81 of the connecting bracket 80, and a clearance hole 33 composed of a longitudinally elongated hole is formed at the position corresponding to the circular hole 82 of the connecting bracket 80.

[0114] By passing a screw 35 through the clearance hole 81 of the connecting bracket 80 and the round hole 31 of the linkage frame 30, and screwing it into the threaded hole 21 of the slider 20, the linkage frame 30 and the slider 20 are connected at one point.

[0115] Two screws 85 (fasteners) are passed through the round hole 82 of the connecting bracket 80 and the clearance hole 33 of the linkage frame 30, and screwed into the threaded hole 26 formed in the slider 20, thereby fixing the connecting bracket 80 to the slider 20 via the linkage frame 30. The connecting bracket 80 is provided as part of the slider 20. The linkage frame 30 and the slider 20 can rotate relative to each other about the aforementioned screws 35 (i.e., the angle can be adjusted).

[0116] Additionally, the auxiliary screw 86 passes through the elongated hole 34 of the linkage frame 30 and is screwed into the threaded hole 27 of the slider 20. This auxiliary screw 86 does not obstruct the angle adjustment between the linkage frame 30 and the slider 20.

[0117] The ring portion 63a of the pull stud 60 is rotatably connected to the linkage frame 30 in the same manner as in the first embodiment. The ring portion 62a of the pull stud 60 is rotatably connected to the linkage bracket 80 by screwing a screw 68 through the collar 65 and the washer 66 into the threaded hole 83 formed in the upper part of the linkage bracket 80.

[0118] Although not shown in the figure, the slider 20 supported on the upper guide rail and the linkage frame 30 are also connected in the same way, but the pull stud can be omitted.

[0119] In the above structure, the operation of correcting the posture of the door 2 by adjusting the length of the pull stud 60 is the same as in the first embodiment, so detailed description is omitted. Before the posture correction operation, screws 35, 85, and 86 are loosened in advance, and then tightened after the posture correction operation is completed. In the posture correction operation using the pull stud 60, the angle between the slider 20 and the linkage frame 30 is adjusted by relative rotation about a screw 35.

[0120] In this embodiment, by overlapping the connecting bracket 80 with the linkage frame 30, the length of the slider 20 can be shortened, and the door 2 can be retracted further into the housing 1 than in the first embodiment.

[0121] <Fourth Implementation Method>

[0122] exist Figure 10 In the door guide device of the fourth embodiment shown, the pull stud 60 (support member) is vertical. The screw 35 (i.e., the rotation center for angle adjustment between the slider 20 and the linkage frame 30) is located at a position offset from the straight line for arranging the pull stud 60. Other structures are the same as in the third embodiment, therefore the same reference numerals are used and descriptions are omitted.

[0123] <Fifth Implementation Method>

[0124] Next, refer to Figures 11-15 A door guiding device according to a fifth embodiment of the present invention will be described. Figure 12 , Figure 14 , Figure 15 The image shows the forward-leaning posture of door 2 before posture correction.

[0125] In this embodiment, the door 2 is pushed in from the open position along the outer surface of the side wall 1b of the housing 1, and a plurality of horizontally extending guide rails 10, such as upper and lower rails, are fixed to the outer surface of the side wall 1b of the housing 1. Similar to the third and fourth embodiments, the door 2 is supported by a plurality of hinge mechanisms 50 provided in the linkage frame 30.

[0126] like Figure 13 As shown, a connecting bracket 90 is arranged between the upper and lower sliders 20 and the linkage frame 30, overlapping with the linkage frame 30. This connecting bracket 90 has a crank shape, with a vertical plate 91 along the guide rail 10, a vertical plate 92 along the linkage frame 30, and a horizontal plate 93 connecting the two in the middle. The connecting bracket 90 is secured to the slider 20 by screwing screws 95 through four circular holes 91a formed in the vertical plate 91 into the threaded holes of the slider 20. The connecting bracket 90 is provided as part of the slider 20. These screws 95 are screwed in via large-diameter working holes 36 formed near the upper and lower ends of the linkage frame 30.

[0127] A circular hole 92a is formed at the front end of the vertical piece 92 of the upper and lower connecting brackets 90. By screwing screws 101 through these circular holes 92a into the upper and lower threaded holes 37 of the linkage frame 30, the linkage frame 30 is connected to the upper and lower connecting brackets 90 at a single point. The screw 101 becomes the center of relative rotation when adjusting the angle between the linkage frame 30 and the upper and lower sliders 20.

[0128] like Figures 13 to 15 As shown, the door guiding device of this embodiment has a support mechanism 100 (support unit) disposed on the outer side of the linkage frame 30 (opposite to the side wall 1b). The support mechanism 100 has a first support member 110 that extends elongatedly in the vertical direction and an inclined second support member 120. These support members 110 and 120 are made of slender plate-shaped rigid bodies and are disposed overlapping the linkage frame 30.

[0129] A circular hole 92b is formed at the rear end of the vertical plate 92 of the upper and lower connecting bracket 90, a circular hole 111 is formed at the upper and lower ends of the first support member 110, and an elongated hole 38 extending in the vertical direction is formed at the corresponding position of the linkage frame 30. Screws 103 and nuts 104 (only when passing through these circular holes 92b, 111, and elongated holes 38) are used to... Figure 15 As shown in the figure, the upper and lower connecting brackets 90 (upper and lower sliders 20) and the upper and lower ends of the first support member 110 are rotatably connected.

[0130] A circular hole 112 is formed at a predetermined distance from the lower end of the first support member 110 upwards, and a vertically extending elongated hole 38' is formed at the corresponding position of the linkage frame 30. By screwing a screw 105 passing through the circular hole 112 and the elongated hole 38' into a nut 106 fixed at one end of the second support member 120, the first support member 110 and the second support member 120 can be rotatably connected around the screw 105.

[0131] By passing the screw 103 through the elongated hole 38 of the linkage frame 30 and the screw 105 through the elongated hole 38', the first support member 110 can be displaced relative to the linkage frame 30 in the vertical direction (the length direction of the linkage frame 30).

[0132] A threaded hole 121 is formed at the other end of the second support member 120, and an elongated hole 39 is formed at the corresponding location of the threaded hole 121 in the linkage frame 30. In this embodiment, the elongated hole 39 is arc-shaped and extends obliquely back and forth. A plurality of engaging recesses 39a are formed along the lower edge of the elongated hole 39. A screw 107 is inserted through the elongated hole 39 of the linkage frame 30 and screwed into the threaded hole 121 of the second support member 120. The shaft portion 107a (engaging shaft portion) of the screw 107 is the same as in the second embodiment, and selectively engages with one of the plurality of engaging recesses 39a of the elongated hole 39. The shaft portion 107a and the elongated hole 39 constitute the adjustment unit 100A.

[0133] The first support component 110, the second support component 120, the connecting bracket 90, and the linkage frame 30 constitute the linkage mechanism shown by the single-dotted line in the figure. Link L90 is formed by the connecting bracket 90, link L30 is formed by the linkage frame 30, link L110 is formed by the first support component 110, and link L120 is formed by the second support component 120. The connection point C1 between link L30 and link L90 is formed by screw 101, the connection point C2 between link L90 and link L110 is formed by screw 103, the connection point C3 between link L110 and link L120 is formed by screw 105, and the connection point C4 between link L30 and link L120 is formed by screw 107. The connecting points C1 to C4 connect the link so that it can rotate. However, since the first support member 110 constituting the link L110 is connected to the upper and lower sliders 20, the link mechanism can be uniquely positioned as long as the engagement position of the shaft portion 107a of the screw 107 and the engagement recess 39a is determined.

[0134] In the fifth embodiment, the main reference is... Figure 14 , Figure 15 This describes the posture correction process for door 2 in a forward-leaning position. During the process of manually manipulating door 2 to change it from a forward-leaning position to an upright position (making the rotation axis of door 2 perpendicular), the linkage frame 30 rotates rearward relative to the slider 20 (connecting bracket 90) around the connecting point C1 (screw 101), i.e., counterclockwise in the figure. Simultaneously, the first support member 110 of the support mechanism 100 also rotates in the same direction and at the same angle as the linkage frame 30. The rotation center of the first support member 110 is located at the connecting point C2 (screw 103). Because it separates from the connecting point C1 (screw 101), which is the rotation center of the linkage frame 30, the first support member 110 is displaced in the length direction (vertical direction) relative to the linkage frame 30.

[0135] As the first support member 110 rotates counterclockwise, the connection point C3 (screw 105) between the first support member 110 and the second support member 120 moves rearward. Consequently, the engagement position of the shaft portion 107a of the screw 107 at the other end of the second support member 120 (connection point C4) moves from the front engagement recess 39a to the rear engagement recess 39a. Thus, the angle between the linkage frame 30 and the slider 20 is adjusted to make the door 2 stand upright.

[0136] The adjusted angle is maintained by the first support member 110 and the second support member 120, which results in maintaining the upright posture of the door 2 (the vertical state of the rotation axis of the door 2).

[0137] Figures 16-18The door guide device of the sixth embodiment shown has four (or more) guide rails 10 fixed to the inner surface of the side wall 1b of the housing 1. The linkage frame 30 is directly connected to each slider 20 by means of three screws 231, 232, and 233. A hinge mechanism 50 is installed in the linkage frame 30 near the slider 20.

[0138] The screw 231 closest to the leading edge of the linkage frame 30 passes through the circular hole formed in the linkage frame 30 and is screwed into the threaded hole of the slider 20 (not shown). Other screws 232 and 233 pass through the longitudinally elongated clearance holes 242 and 243 formed in the linkage frame 30 and are screwed into the threaded holes of the slider 20. The clearance hole 243 near the trailing edge of the linkage frame 30 is longer than the clearance hole 242 located in the middle. The lengths of the clearance holes 242 and 243 are longest at the bottom layer and decrease towards the upper layers. Through this connection structure, the linkage frame 30 can be angularly adjusted relative to the slider 20 of each layer, centered on the leading screw 231.

[0139] <Sixth Implementation Method>

[0140] In the sixth embodiment, a support mechanism 200 (support unit) similar to that in the fifth embodiment is used. This support mechanism 200 has a first support member 210 that extends elongatedly in the vertical direction and an inclined second support member 220. These support members 210 and 220 are constructed of elongated plate-shaped rigid bodies.

[0141] The first support member 210 in this embodiment differs from that in the fifth embodiment in that it is positioned behind the linkage frame 30 without overlapping with it. The first support member 210 is directly connected to the sliders 20 of each layer via two screws 235 and 236. The rear screw 235 passes through a circular hole formed in the first support member 210 and is screwed into a threaded hole in the slider 20 (neither shown in the figure), while the front screw 236 passes through a longitudinal clearance hole 246 formed in the first support member 210 and is screwed into a threaded hole in the slider 20. Through this connection structure, when the linkage frame 30 is angularly adjusted relative to the sliders 20 of each layer, the first support member 210 can rotate relative to the sliders 20 about the screw 235 as the center.

[0142] In the first support member 210, a circular hole (not shown) is formed at a predetermined distance from the lower end upward. The first support member 210 and the second support member 220 are rotatably connected about the pin 250 by riveting a pin 250 passing through the circular hole to the second support member 220.

[0143] A threaded hole (not shown) is formed at the other end of the second support member 220, and an elongated hole 39 is formed in the linkage frame 30. Multiple engaging recesses 39a are formed along the lower edge of the elongated hole 39. A screw 260 is inserted through the elongated hole 39 of the linkage frame 30 and screwed into the threaded hole of the second support member 220. The shaft portion (engaging shaft portion) of the screw 260 engages selectively with one of the multiple engaging recesses 39a of the elongated hole 39. The shaft portion of the screw 260 and the elongated hole 39 constitute the adjustment unit 200A.

[0144] The first support component 210, the second support component 220, the slider 20, and the linkage frame 30 constitute the linkage mechanism shown by the single-dotted line in the figure. Link L20 is formed by the slider 20, link L30 by the linkage frame 30, link L210 by the first support component 210, and link L220 by the second support component 220. The connection point C1 between link L30 and link L20 is formed by screw 231, the connection point C2 between link L20 and link L210 is formed by screw 235, the connection point C3 between link L210 and link L220 is formed by pin 250, and the connection point C4 between link L30 and link L220 is formed by screw 260.

[0145] The posture correction process of door 2 in the sixth embodiment is the same as that in the fifth embodiment, so detailed description is omitted. Preferably, before the posture correction process, the screws 231 to 233 connecting the sliders 20 of each layer and the linkage frame 30, as well as the screws 235 and 236 connecting the sliders 20 of each layer and the first support member 210, are loosened in advance, and then tightened after the posture correction process is completed.

[0146] The present invention is not limited to the above-described embodiments, and various modifications can be adopted without departing from its spirit.

[0147] In Figure 1~ Figure 4 In the first embodiment shown, the linkage frame 30 can also be positioned at the front of the upper and lower sliders 20. In this case, the lower connecting bracket 40 is positioned at the rear of the slider 20, and the inclination of the pull stud 60 is opposite to that in the first embodiment. Therefore, the posture of the door is corrected by shortening the length of the pull stud 60. In this structure, since the hinge mechanism 50 is provided in the linkage frame 30, the upper connecting bracket 40 is not required. The second embodiment can also employ the same structure.

[0148] In the first to sixth embodiments, the support unit may be disposed on the upper part of the door guide device, or on both the upper and lower parts.

[0149] Alternatively, the opening in the housing can be opened and closed using two doors on the left and right. In this case, two sets of door guide devices are required.

[0150] In the first to fourth and sixth embodiments, the door can also be pushed in from the open position along the outer surface of the side wall of the housing. In this case, the guide rail is fixed to the outer surface of the side wall. Similarly, in the fifth embodiment, the door can also be pushed in along the inner surface of the side wall.

[0151] In the above embodiment, a hinge mechanism with four movable axes of rotation was used, but a simpler hinge mechanism with only one axis of rotation (a so-called single-axis hinge) can also be used. This axis of rotation is located in a fixed position and does not move.

[0152] Multiple hinge mechanisms are used in the above embodiments, but a single, elongated hinge mechanism (e.g., a single-axis hinge) extending in the vertical direction can also be used. In this case, the hinge mechanism is mounted on the vertical frame.

[0153] The number of guide rails can be selected appropriately based on the weight of the door.

[0154] In embodiments where the hinge mechanism for supporting the door is located in the vertical frame, a single guide rail may be used if the door is relatively light. In this embodiment, the structures of the first to sixth embodiments described above can be appropriately used.

[0155] When a door guide device is installed on a pre-determined storage body and door, the angle between the vertical frame and the slider that will maintain the door in an upright position can be predetermined since the degree of forward tilt of the door is known. Therefore, it is also possible to pre-form connecting parts (e.g., the positions of locking holes) on the vertical frame and the slider to maintain this angle, and connect the two ends of the support member made of a rigid body to these connecting parts. In this case, the adjustment device can be omitted.
