[0001]

[Technical field to which the invention belongs]

 The present invention relates to a storage room with an interlocking sliding door in which, when the first sliding door is moved, the second sliding door automatically moves by a half movement amount in the moving direction of the first sliding door.

[0002]

[Prior art]

 The storeroom is provided with an entrance for carrying in and out articles. A storage room with an interlocking sliding door that opens and closes the entrance with a double sliding door is known.

[0003] The storage room with an interlocking sliding door has a first sliding door capable of opening and closing an entrance and a second sliding door, and when the first sliding door is moved, the second sliding door is moved in half in the moving direction of the first sliding door. Many are equipped with a sliding door interlocking device that moves by the amount of movement.

[0004] Here, as a sliding door interlocking device, for example, as disclosed in Japanese Patent Application Laid-Open No. 11-44157, there is a device using a rack and pinion mechanism.

[0005] The sliding door interlocking device using the rack and pinion mechanism includes a fixed rack fixed to a frame body located above the first sliding door and the second sliding door and extending along the opening and closing movement direction of the sliding doors. And a pinion rotatably mounted on the second sliding door and meshing with both the fixed side rack and the moving side rack facing the fixed side rack, and the first sliding door and the second sliding door are interlocked with a moving amount of 2: 1.

[0006]

[Problems to be solved by the invention]

 By the way, in a storage room with an interlocking sliding door provided with a sliding door interlocking device using the rack and pinion mechanism, the pinion and the rack have poor meshing accuracy, or the first and second sliding doors move up and down while moving in the opening and closing movement direction. When the pinion is displaced in the direction, the pinion bites into the fixed rack or the movable rack, and the first sliding door and the second sliding door cannot be smoothly opened and closed. Also, the meshing between the pinion and the rack may not be performed smoothly, and an unpleasant meshing sound may be generated.

An object of the present invention is to provide an interlocking sliding door that can smoothly open and close an entrance by moving a first sliding door and a second sliding door in an interlocking movement direction, and can prevent unpleasant noise when opening and closing. To provide a storeroom.

[0008]

[Means for Solving the Problems]

 The invention according to claim 1 has a first sliding door and a second sliding door capable of opening and closing an entrance, and when the first sliding door is moved, the second sliding door is moved by half in the moving direction of the first sliding door. In a storeroom with an interlocking sliding door provided with a sliding door interlocking device to be moved by a sliding door, the sliding door interlocking device has a connecting link whose lower end is rotatably supported by a fixed body near the entrance, and the upper end of this connecting link is The first sliding mechanism is connected to the drawer side end of the first sliding door movably in the vertical direction via the first sliding mechanism, and the center of the link is connected to the drawer side end of the second sliding door 20 via the second sliding mechanism. The part is movably connected in the vertical direction.

In the present invention, for example, in FIG. 3, when the first sliding door 10 is moved from the lower end 34 of the connecting link 31 to the position of X1 in the closing movement direction (the direction of arrow E), the connecting is performed. The lower end 34 of the link 31 is at the point A, the center 33 is at the point B, the upper end 32 is at the point C, the line segment AB = the line segment BC = S, the horizontal line passing through the point A is L, and the horizontal line L is Assuming that the legs of the perpendiculars lowered from points B and C are point D, point E, line segment AD is X2, and line segment AE is X1,

[0010] ΔABD and ΔACE are similar because the following equation holds.

∠BAD = ∠CAE (common), ∠ABD = ∠ACE (isotopic angle), ∠ADB = ∠ AEC = right angle

Therefore, since the line segment AB: the line segment AD = the line segment AC: the line segment AE,

S: X2 = 2S: X1∴X2 = (１ ／) · X1

As described above, when the first sliding door 10 is moved by an arbitrary length, the second sliding door 20 is moved by a half movement amount in the moving direction of the first sliding door 10.

As described above, the sliding door interlocking device (30) is a slide link mechanism, and the connecting link 31 and each of the sliding doors (10, 20) are movably connected in the vertical direction. The fixed body (3) and the sliding doors (10, 20) are connected to the connecting link 31 with slightly lower dimensional accuracy, and the sliding doors (10, 20) are displaced in the vertical direction while moving in the opening and closing movement direction. However, since the dimensional error, displacement, and the like can be absorbed, the sliding doors (10, 20) and the link 31 smoothly move relative to each other. As a result, the door 1 can be opened and closed by smoothly moving the first sliding door 10 and the second sliding door 20 in the opening and closing movement direction in conjunction with each other, and it is possible to prevent generation of unpleasant noise during opening and closing.

When the first sliding door 10 is moved in the closing movement direction (the direction of arrow E), the connecting link 31 rotates clockwise in FIG. 3 around the support shaft 35 by its own weight. The first sliding door 10 and the second sliding door 20 are urged in the closing movement direction (the direction of the arrow E) via the first sliding mechanism 41 and the second sliding mechanism 45. Therefore, the door 1 can be closed by moving the first sliding door 10 and the second sliding door 20 in the closing movement direction with a lower force.

The invention of claim 2 has a first sliding door and a second sliding door capable of opening and closing an entrance, and when the first sliding door is moved, the second sliding door is moved in half in the moving direction of the first sliding door. In a storage room with an interlocking sliding door provided with a sliding door interlocking device that moves by an amount of movement of the second sliding door, the sliding door interlocking device has a connecting link whose center portion is rotatably supported at a drawer side end of the second sliding door, The upper end of the link is movably connected to the drawer-side end of the first sliding door via a one-side slide mechanism, and the lower end of the connection link is connected to the vicinity of the entrance via the other slide mechanism. It is characterized in that it is connected to the fixed body so as to be vertically movable.

In the present invention, for example, in FIG. 7, when the first sliding door 10 is moved from the lower end 34a of the connecting link 31A to the position of the length X1 in the closing movement direction (the direction of arrow E), the connecting link 31A The lower end 34a has a point A, the center 33a has a point B, the upper end 32a has a point C, a line AB = a line BC = S, a horizontal line passing through the point B is L, and points A and Assuming that the legs of the perpendicular descended from point C are point D, point E, line segment DB is X2, and line segment DE is X1,

ΔABD and ΔCBE are congruent because the following equation is satisfied.

∠ABD = ∠CBE (vertical angle), ∠BAD = ∠BCE (complex angle), ∠ADB = ∠ CEB = right angle

Therefore, X2 = (１ ／) · X1

As described above, when the first sliding door 10 is moved by an arbitrary length, the second sliding door 20 is moved by a half movement amount in the moving direction of the first sliding door 10.

As described above, the sliding door interlocking device (30A) is a slide link mechanism, and the connecting link 31A and each sliding door (10, 20) are connected so as to be relatively movable in the vertical direction. Therefore, if the fixed body (3) and the sliding doors (10, 20) are connected to the connecting link 31 with slightly lower dimensional accuracy, respectively, or if the sliding doors (10, 20) move in the opening and closing movement direction, the vertical direction may be changed. Therefore, the sliding doors (10, 20) and the connecting link 31 smoothly move relative to each other because the dimensional error and the displacement can be absorbed. As a result, the door 1 can be opened and closed by smoothly moving the first sliding door 10 and the second sliding door 20 in the opening and closing movement direction in conjunction with each other, and unpleasant noise can be prevented from being generated during opening and closing.
