  The present invention relates to furniture such as a library having three or more sliding doors.

In a furniture such as a library having three or more sliding doors, a sufficient opening cannot be obtained by a simple operation of opening one sliding door if there is no linkage with other sliding doors. The same applies when closing. Therefore, it is common to provide a link mechanism for interlocking each sliding door. Patent Document 1 below discloses a link mechanism using a single interlocking member 6. This is a so-called I-type link. In addition, there are V type, reverse V type, Y type, reverse Y type, X type and the like using two interlocking members. A lock 15 is provided at a position adjacent to one of the two support shafts 14 corresponding to the moving connecting portion of the present application, and the locking member 17 is locked to the support shaft 14 to restrict the movement of the link mechanism. ing. That is, in the disclosure of this document 1, the lock is limited to the vicinity of the position of the support shaft in a state where each sliding door is closed. In Patent Document 2, the reverse V-type link mechanism described above is used, but the vertical movement of the rotation center shaft 56 corresponding to the moving connecting portion and the roller 55 attached thereto is set apart at predetermined positions. A mechanism is disclosed in which a stop bar 65 extending in the left-right direction from near the lock is rotated and driven by an operation of the lock. Therefore, the lock can be provided at a position separated from the movable connecting portion.

However, in the stop bar using mechanism of the above-mentioned document 2, the installation position of the lock is limited to the vicinity of one end of the bar, and the lock cannot be installed at different height positions using the same bar.
Therefore, the problem to be solved is to provide furniture in which the height position of the lock installation can be selected by one long member.

In the first invention, the furniture is configured such that the opening is opened and closed by three or more sliding doors, and includes a link mechanism that is associated with another sliding door when the sliding door is opened or closed. The link mechanism does not change the connection position with the sliding door during the opening / closing operation, and the movement is such that the connection position between the non-moving connection portion that can freely rotate at that position and the sliding door moves in the vertical direction. A long member having a restricting portion and extending in the moving direction of the movable connecting portion, and is provided so as to be able to stand up and fall down, and the restricting portion moves when the long member is in a lying state. The movement of the connecting portion is not restricted but restricted in the standing state, and the long member is provided with engaging portions at a plurality of positions separated in the longitudinal direction of the long member. , By operating the lock provided near the long member And each other engage with the driven member to be, erected the long elongated member, providing a furniture, characterized in that it is possible to lodging.
For example, in the case of combination furniture combined with the top and bottom, each is furniture, and in determining whether it is infringement, it can be determined whether or not any one of upper and lower is applicable to the first invention.

  In the second invention, each is the furniture of the first invention, which is a combination of the lower furniture and the upper furniture placed on the lower furniture, each 3 There are two or more sliding doors, the engaging portion is provided at each longitudinal end of the long member or in the vicinity thereof, and the same type of long member is provided along the vertical direction of the lower furniture and the upper furniture, respectively. In the lower furniture, the lock is provided at a position adjacent to the upper engaging portion, and in the upper furniture, the lock is provided at a position adjacent to the lower engaging portion.

  In the first aspect of the invention, the driven member is operated by the lock so that the long member is raised or laid down, and the movement of the moving connecting part due to the operation of the link mechanism is regulated by the regulating part provided thereto, or the regulation is released. I can do it. Therefore, the opening of the opening by the sliding door is restricted or made openable. Here, since the long member is provided along the up-and-down movement direction of the movable connecting portion, the lock member can be selected from a plurality of engaging portions provided on the long member according to the height of the furniture. The engaging portion corresponding to the mounting height can be selected. In the case of providing a window in a sliding door of furniture, in the case of the above-mentioned Patent Document 2, since the stop bar extends in the left-right direction, the bar member can be seen from the window or hidden in the metal plate frame around the window However, since the position is limited to the upper end or the lower end of the sliding door and the height position is limited, the long member according to the present invention is in the vertical direction, so the metal plate on the left edge or right edge of the window It can be hidden and arranged along the back of the frame, a desired engagement portion can be selected from a plurality of engagement portions having different height positions, and the installation height of the lock can be selected. Furthermore, since the engaging portions are provided at a plurality of locations in the longitudinal direction of the long member, it is possible to use it for a plurality of furniture having different installation heights by producing only one type of this long member. Cost reduction is possible.

  In the second invention, in the lower furniture, the lock is provided at a position adjacent to the upper engagement portion, and in the upper furniture, the lock is provided at a position adjacent to the lower engagement portion. The locks can be collected and provided in the height region, and the lock operation by a person becomes easy.

Hereinafter, the present invention will be described in more detail based on an embodiment shown in the accompanying drawings.
FIG. 1 is a front view of a storage cabinet placed one above the other as furniture according to the present invention, FIG. 2 is a main part rear view seen from the back side of the sliding door of the upper furniture 10, and FIG. 3 is a main part of FIG. FIG. 4 is a bottom view seen from the direction of the arrow D in FIG. 3, and FIG. 5 is a view different from the state of FIG. The upper furniture 10 and the lower furniture 10 'each have three sliding doors D1, D2, D3; D1', D2 ', D3'.

  In the upper furniture, the pullers H1 and H2 are provided in the lower positions of the right sliding door D1 and the left sliding door D3. In the lower furniture, the pullers H1 ′ and H1 ′, H2 ′ is provided. Further, a key cylinder 20 as a lock is provided near the handle H1 and slightly below, and a key cylinder 20 'as a lock is provided near the handle H1 ′ and slightly below. It has been. That is, both the handle and the lock are provided in a range where the user can reach in a natural posture in which the user stands. As a result, when the user opens and closes the sliding door, the user can easily place the hand on each pulling handle while keeping the natural posture of the upper furniture and the lower furniture, and may be locked or unlocked. Similarly, the operation becomes easy with a natural posture.

  As the basic member of the link mechanism for interlocking the sliding doors in both the upper and lower furniture, the interlocking bar 12 is provided at the lower part of each sliding door in the closed state so as to be gently inclined as shown by the broken line in FIG. Considering that the interlocking bar 12 cannot be seen from the transparent glass window W of each sliding door when each sliding door is closed, the width dimension of the metal plate frame surrounding the window W is set. That is, in both the upper and lower furniture, the vertical width dimension of the lower frame part of each sliding door is larger than the vertical width dimension of the upper frame part. Referring mainly to FIG. 2, one end of the interlocking bar 12 is connected to the lower protrusion of the left sliding door D3 so as to be rotatable about the pivot axis J3, and the connecting position with respect to the left sliding door D3 is unchanged and is not moved. It is a connecting part.

  On the other hand, a roller R1 that is rotatable about the pivot axis J1 is attached to the other end of the interlocking bar. Further, the guide rail member G1 fixed to the metal plate frame D1B of the sliding door D1 near the furniture housing and extending in the vertical direction holds the other end portion movably in the vertical direction via the roller R1. is doing. This other end, that is, the pivot axis J1 and the roller R1 is the moving connecting portion. A plate member 13 having a short predetermined length is fixed to the central portion of the interlocking bar in the longitudinal direction, and another roller R2 is attached to the end of the plate member so as to be rotatable about the pivot axis J2. ing. This end portion, that is, the pivot axis J2 and the roller R2 are also moving connecting portions. On the other hand, another guide rail member G2 is provided in the vertical direction at a portion of the middle sliding door D2 next to the closed right sliding door D1, and the roller R2 is held and guided by the guide rail member G2.

  Therefore, for example, when the user pulls the sliding door H2 of the left sliding door D3 and pulls the sliding door to open the furniture opening, the interlocking bar 12 moves the roller R1 upward along the guide rail member G1. However, while moving the roller R2 upward along the guide rail member G2, the middle sliding door D2 is also moved toward the right sliding door D1 while increasing its inclination. That is, each sliding door is interlocked. Along the guide rail member G1, a long member 14 having substantially the same length is disposed near the door surface of the sliding door D1. This long member is engaged and attached to the guide rail member G1 fixed to the metal plate frame D1B of the sliding door D1 through the flange portion 14F, and the vertical line (longitudinal direction of the long member) is the center. It is provided as a shaft so that it can stand up and fall freely.

  An engaging portion 14K is provided at the lower end in the longitudinal direction of the attached long member. On the other hand, the key cylinder 20 is mounted on the metal plate frame D1B so as to be positioned beside the engaging portion, and one end portion of the driven member 22 that is driven forward and backward by the key operation is connected to the engaging portion 14K. Locked. When locked by key operation, the long member rises and becomes as shown in FIG. On the other hand, when unlocked, it falls over and becomes like FIG. Further, a regulating portion KB standing toward the connection bar is mounted and fixed on the surface of the long member 14 on the connection bar 12 side. The mounting position of the long member in the longitudinal direction is a position close to the end portion of the interlocking bar 12 where the roller R1 is provided in the state of FIG. In the state where the long member is raised, the restricting portion has a height that restricts the movement of the end of the interlocking bar where the roller R1 is located.

Therefore, if the lock 20 is locked, none of the three sliding doors can be opened. On the other hand, when unlocked, as shown in FIG. 5, the restricting portion KB falls so as to approach the metal plate frame D <b> 1 </ b> B side of the sliding door D <b> 1 and does not interfere with the movement of the interlocking bar 12. Therefore, the sliding door can be opened.
On the other hand, another engaging portion 14K ′ is provided at the upper end in the longitudinal direction of the long member. In the upper furniture 10, the engaging portion at the upper end of the long member 14 is not used. However, in the lower furniture 10 ′, the long member 14 having the same size and shape as the upper furniture is disposed in the same manner on the back side of the right metal plate frame of the right sliding door D1 ′. A lock 20 'is disposed beside the engaging portion 14K', the engaging portion 14K 'is used, and the engaging portion 14K at the lower end is not used.

Therefore, by making one type of long member 14, it can be used in common for both upper and lower furniture, and two types of alternative members can be made for inventory control while assembling. The cost of the whole furniture can be reduced rather than using properly.
In the above example, the lock is a type in which the driven member driven by key operation moves forward and backward, but the elastic member such as a spring member so as to constantly urge and press a long member that can stand up and fall in the lying down direction. The member is mounted, and the lock is a type in which the driven member is rotated by a key operation, and the long member can be raised against the urging force of the elastic member by this rotation.

  In the above example, the attachment position of the long member and the lock is the left and right ends of the furniture, but the upward movement of the roller R2 having the pivot axis J2, which is the moving connecting portion at the center of the interlocking bar, should be directly restricted. A long member having a restricting portion and a lock may be provided at a position closer to the center. Furthermore, the link mechanism of the above example is a so-called I type. For example, in the case of a V type or the like in which the central connecting portion is a moving connecting portion, the position is closer to the center of the furniture corresponding to this position. A long member and a lock may be provided. Furthermore, although two engaging parts are the lower end part and upper end part of a elongate member, positions other than an edge part may be sufficient. Moreover, you may provide the engaging part in three or more positions. Moreover, although the said example is the furniture which has the window W, the sliding door of such a full metal plate without a window may be sufficient.

  The present invention can be used for furniture such as a library having three or more sliding doors.

FIG. 1 is a front view of furniture according to the present invention. FIG. 2 is a main part rear view seen from the back side of the sliding door of the upper furniture. FIG. 3 is an enlarged view of a main part of FIG. FIG. 4 is a bottom view seen from the direction of arrow D in FIG. FIG. 5 is a diagram showing a state different from the state of FIG.
