Description

[Detailed description of the invention] (a) Industrial application field The present invention relates to an opening/closing structure for a sliding door in which both door panels are located on the same plane in the closed state.

(b) Conventional technology Conventionally, doors are pivotally attached to storage compartments such as closets so that they can be opened and closed freely, but it is necessary to secure a swinging space for opening and closing the door, which reduces the amount of indoor space. The disadvantage was that it was a dead space and the limited indoor space could not be used effectively. In addition, when sliding doors are used for the storage area, there is a difference in level between the two door plates, which makes it difficult to get rid of the image of a storage area such as a conventional storage door.
The drawback was that it was difficult to achieve total furniture in the room.

(C) Purpose The present invention eliminates these drawbacks, makes it possible to effectively utilize the limited indoor space, and also revamps the image of conventional storage compartments, creating a total interior decoration. The purpose of the present invention is to provide a sliding door opening/closing structure that can be opened and closed.

(D) Structure Therefore, the feature of the present invention is that the pair of door panels, each guided in the longitudinal direction of the rail and attached to the opening side of the storage section so as to be openable and closable, always keep one door panel on the storage section side. Due to the biasing force of the resilient member, when the opening of the storage section is closed, opposing end surfaces that are located on the same plane and that are close to or in contact with each other are provided with one side during the opening/closing operation. This is because a sliding slope is formed to guide the door plate.

(E) Embodiments The present invention will be explained in detail below based on illustrated embodiments.

In FIGS. 1 and 2, 1 is a storage section such as a closet, and the upper edge of the storage section 1 on the opening 2 side has 2
The rails 3 and 4 of the strips are fixed, and a pair of door panels 5 and 6 are fixed.
is guided by the rails 3 and 4 and attached to the opening 2 side so as to be openable and closable.

Specifically, one of the door panels 5 and 6
Support rollers 7 are rotatably supported around a support shaft 8 at both left and right ends of the upper part of the door panel (left side door in Figure 1), and the door panel 5 is held suspended from the rail 3 via the support rollers 7. has been done. Further, a bracket 10 with guide rollers 9 attached is fixed to both left and right ends of the lower part of the door plate 5, and is attached to one groove 12 of a guide member 11 having an E-shaped cross section fixed to the lower edge of the opening 2 side of the storage section 1. The guide roller 9 is rotatably fitted. Further, one side end surface (right side in the figure) of the door plate 5 has a sliding slope 13 cut out therein, and a guide member 14 made of, for example, nylon is coated on the slope 13.

On the other hand, one end of a pair of support links 15 and 16 is pivotably attached to the upper edge of the door plate 6 (the door plate on the right side in FIG. 1), and a pair of support links 15 and 16 that roll in the longitudinal direction of the rail 4 The support link 1 is attached to a holder member 19 that holds the support roller 17 around the support shaft 18.
The other ends of 5 and 16 are pivotally connected to the support link 1.
A door plate 6 is suspended from the rail 4 via 5 and 16.

Further, a resilient member 20 such as a coil spring is stretched between the door plate 6 and the holder member 19, and the door plate 6
is always biased toward the storage section 1 side. Further, one side end face (left side in the figure) of the door plate 6 is cut out with a sliding slope 21 corresponding to the slope 13 provided on the door plate 5, and a guide member 22 made of, for example, nylon is formed as a notch in the same manner as described above. The inclined surface 21 is coated. One end of a pair of guide links 23 is pivotally attached to both left and right ends of the lower part of the door plate 6, and a guide roller 24 is provided at the other end of the guide link 23. A guide roller 24 is rotatably fitted. Reference numeral 26 denotes a stopper against which the inclined surface 13 of the door plate 5 comes into contact in the open state.

The sliding slope 21 of the sliding door 6 is located on the side opposite to the storage section side with respect to the sliding slope 13 of the sliding door 5.
3 is located on the storage section side with respect to the sliding slope 21 of the sliding door 6.

Thus, the first opening 2 of the storage section 1 is closed.
In the state shown in the figure, both door plates 5 and 6 are located on the same plane due to the biasing force of the resilient member 20, and both inclined surfaces 13 and 21 are in a facing state in which they are close to each other or in contact with each other.

Next, to explain an example of the use of the double sliding door configured in this way, the solid line in FIG. If one door panel 5 is pressed in the direction of arrow A from this state, the inclined surface 13 of the door panel 5 will press the inclined surface 21 of the other door panel 6. At this time,
The inclined surface 21 of the other door panel 6 slides on the inclined surface 13 of the one door panel 5 due to the pressing force, and as a result, the door panel 6 resists the biasing force of the resilient member 20 and moves as shown in the imaginary line. protrudes slightly forward. Further, when the door plate 5 is pressed in the direction of arrow A, both door plates 5 and 6 overlap as shown in FIG. 2, opening the left side of the storage section 1.

In addition, in order to close the opening 2 of the storage section 1, by pulling one door plate 5 in the direction of arrow B, the inclined surface 21 of the other door plate 6 is moved to the inclined surface 1 of the one door plate 5.
3 is slid in the opposite direction to the above and retreated by the action of the biasing force of the resilient member 20, resulting in the state shown by the solid line in FIG. In this state, both door plates 5 and 6 are located on the same plane and close the opening 2 of the storage section 1.
Note that in order to open the right side of the opening 2 of the storage section 1, the door plate 6 may be pressed in the direction of the arrow B in the opposite manner to the above operation, so a description thereof will be omitted.

(f) Effects Since the present invention is configured as described above, there is no need to secure a swinging space (dead space) like a door, and the limited indoor space can be effectively utilized. In addition, when the opening of the storage compartment is closed, both door plates lie on the same plane, eliminating the difference in level that occurs with conventional sliding doors, creating a piece of furniture with a flat, simple, modern feel. It is possible to renew the image of storage areas such as closets and create total fashion indoors.

Claims (1)

[Scope of utility model registration request] A pair of door plates, each guided in the longitudinal direction of the rail and attached to the opening side of the storage compartment so as to be openable and closable, are supported by the biasing force of an elastic member such as a coil spring that constantly biases one door plate toward the storage compartment side. Therefore, when the opening of the storage section is closed, a guide member made of nylon or the like is provided on opposing end surfaces that are located on the same plane and are close to or in contact with each other, and that guide one door plate during opening and closing operations. A covered sliding inclined surface is formed, and the sliding inclined surface formed on the opposing end surface of the one door plate is on the storage section side with respect to the opposing end surface of the door plate other than the one door plate. One end of the one door plate is pivotally attached to a holder member that holds a roller that rolls in the longitudinal direction of the rail around its spindle, and the other end is located on the opposite side of the one door plate. An opening/closing structure for a sliding door, characterized in that the sliding door is supported by a pair of support links pivotably attached to the upper edge.
