An embodiment of the present invention will be described in detail below with reference to the drawings.
FIG. 1 is a perspective view showing a guide device 1 of this embodiment. As shown in FIG. 1, the guide device 1 of the present embodiment is preferably used for a hanging sliding door D that is movable in the opening/closing direction x while being separated from the floor surface F in the vertical direction z.

Here, in this specification, the opening/closing direction x is the direction in which the upper hanging sliding door D moves when opened/closed, and corresponds to the direction indicated by symbol x in FIG. Further, the door thickness direction y is the thickness direction of the hanging sliding door D, and corresponds to the direction indicated by symbol y in FIG. A vertical direction z is a direction orthogonal to the opening/closing direction x and the door thickness direction y, and corresponds to the direction indicated by symbol z in FIG.

In this specification, the opening/closing direction x includes the closing direction x1 and the opening direction x2. Also, the vertical direction z includes an upward direction z1 and a downward direction z2. Further, the directions specified in the members constituting the guide device 1 correspond to the directions when the guide device 1 is attached to the upper hanging sliding door D and the floor surface F, respectively.

2 is a cross-sectional view of the guide device 1, and FIG. 3 is a cross-sectional view of the guide device 1 when the hanging sliding door D in FIG. 2 moves in the closing direction x1. As shown in FIGS. 2 and 3, the guide device 1 of this embodiment includes a guide pin 2 provided on the floor surface F, a guide groove 3 provided on the lower surface Da of the hanging sliding door D, and adjacent to the guide groove 3 . and a guide receiver 4 provided as a

The guide pin 2 is desirably provided so as to protrude from the floor surface F in the upward direction z1. The guide pin 2 of this embodiment includes a fixed member 21 fixed inside the floor surface F, a first member 22 held by the fixed member 21 so as to be movable in the vertical direction z, and a vertical direction of the first member 22. and a second member 23 movably held at z. Since such a guide pin 2 is accommodated in the floor surface F when it is not engaged with the upper sliding door D, the floor surface F can be made flat when the upper sliding door D is opened.

When the protrusion height of the second member 23 exceeds the movable range of the second member 23, the guide pin 2 preferably protrudes in the upward direction z1 as shown in FIG. It is desirable that the first member 22 protrude in the upward direction z1 even when the first member 22 and the second member 23 are temporarily stuck together due to foreign matter being caught therein.

Such a guide pin 2 has a large allowable value for the space between the hanging sliding door D and the floor surface F in the vertical direction z. Further, even when the first member 22 and the second member 23 are temporarily fixed, the guide pin 2 can be used as a guide for the upper sliding door D if at least a part of the second member 23 protrudes from the first member 22 . It can function as the device 1 .

As shown in FIGS. 2 and 3, the guide groove 3 of this embodiment has a groove portion 31 that allows the second member 23 of the guide pin 2 to slide in the opening/closing direction x. The guide groove 3 is made of resin or non-magnetic metal, for example. When the guide grooves 3 are made of resin, for example, ABS resin is preferably used. If the guide groove 3 is made of a non-magnetic metal, it is preferably selected from titanium, aluminum and the like. By engaging with the guide pin 2, such a guide groove 3 can suppress the movement of the upper hanging sliding door D in the door thickness direction y without hindering the movement of the upper hanging sliding door D in the opening/closing direction x.

The guide receiver 4 of this embodiment includes a main body member 41 fixed to the lower surface Da of the upper hanging sliding door D, and a groove portion 31 of the guide groove 3 by projecting the second member 23 of the guide pin 2 from the floor surface F by magnetic force. and a guiding holder member 42 .

In the holder member 42 of this embodiment, a lower end surface 42a when viewed in the door thickness direction y is an inclined surface whose height in the vertical direction z increases toward the guide groove 3 side. Such a guide device 1 causes the second member 23 of the guide pin 2 to gradually protrude upward z1 along the lower end surface 42a of the holder member 42 as the upper hanging sliding door D moves in the closing direction x1. 3 can be guided to a height where it can be engaged with the groove portion 31 .

The holder member 42 is arranged, for example, on the body member 41 so as to be slidable in the vertical direction z. Such a guide device 1 has a large allowable value for the interval in the vertical direction z between the floor surface F and the hanging sliding door D, and even if the distance varies depending on the construction state of the mounting position of the hanging sliding door D, can guide you. Further, even if the holder member 42 and the guide pin 2 come into contact with each other, the guide device 1 can move the holder member 42 in the upward direction z1 regardless of the state of contact, thereby suppressing damage. Note that the guide receiver 4 may be formed by integrally forming the body member 41 and the holder member 42 .

As shown in FIGS. 2 to 4, the main body member 41 of the guide receiver 4 of this embodiment has a recess 43 that opens at least in the downward direction z2 when fixed to the lower surface Da of the upper sliding door D. . For example, the concave portion 43 may penetrate in the up-down direction z in a single product state before being fixed to the lower surface Da of the upper hanging sliding door D. As shown in FIG.

The holder member 42 of this embodiment is arranged in the recess 43 . Such a concave portion 43 can accommodate the holder member 42 so as to be slidable in the vertical direction z. Note that even when the body member 41 and the holder member 42 are integrally formed, the holder member 42 is provided inside the recess 43 .
