[Figure 8] FIG. 4 is a side view of the guide device as viewed from the closing direction. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0016] Hereinafter, an embodiment of the present invention will be described in detail 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 this embodiment is suitably used for an upper hung sliding door D that is movable in an opening / closing direction x while being spaced apart from a floor surface F in a vertical direction z.

[0017] Here, in this specification, the opening / closing direction x is the direction in which the upper hanging sliding door D moves when it is opened or closed, and corresponds to the direction indicated by the symbol x in Fig. 1. The door thickness direction y is the thickness direction of the upper hanging sliding door D, and corresponds to the direction indicated by the symbol y in Fig. 1. The up-down direction z is the direction perpendicular to the opening / closing direction x and the door thickness direction y, and corresponds to the direction indicated by the symbol z in Fig. 1.

[0018] In this specification, the opening / closing direction x includes a closing direction x1 and an opening direction x2. The up-down direction z includes an upward direction z1 and a downward direction z2. Furthermore, the directions specified by the members constituting the guide device 1 correspond to the directions when the guide device 1 is attached to the upper suspended sliding door D and the floor surface F, respectively.

[0019] Fig. 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 upper suspended sliding door D in Fig. 2 moves in the closing direction x1. As shown in Fig. 2 and Fig. 3, the guide device 1 of this embodiment includes a guide pin 2 provided on a floor surface F, a guide groove 3 provided on a lower surface Da of the upper suspended sliding door D, and a guide receiver 4 provided adjacent to the guide groove 3.

[0020] The guide pin 2 is desirably provided so as to be able to protrude in the upward direction z1 from the floor surface F. 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 second member 23 held by the first member 22 so as to be movable in the vertical direction z. Since such a guide pin 2 is housed within the floor surface F when not engaged with the overhead sliding door D, the floor surface F can be made flat when the overhead sliding door D is opened.

[0021] 3, when the protruding height of the second member 23 exceeds the movable range of the second member 23, it is desirable for the first member 22 to protrude in the upward direction z1. It is also desirable for the first member 22 to protrude in the upward direction z1 when the first member 22 and the second member 23 are temporarily fixed to each other due to the inclusion of a foreign object or the like.

[0022] Such a guide pin 2 has a large tolerance for the distance in the vertical direction z between the overhead sliding door D and the floor surface F. Furthermore, this guide pin 2 can function as a guide device 1 for the overhead sliding door D even when the first member 22 and the second member 23 are temporarily fixed to each other, as long as at least a part of the second member 23 protrudes from the first member 22.

[0023] 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, for example, resin or non-magnetic metal. When the guide groove 3 is made of resin, for example, ABS resin is preferably used. When the guide groove 3 is made of non-magnetic metal, it is preferable to select titanium, aluminum, etc. Such a guide groove 3 can suppress movement of the upper hanging sliding door D in the door thickness direction y by engaging with the guide pin 2 without impeding movement of the upper hanging sliding door D in the opening / closing direction x.

[0024] The guide receiver 4 in this embodiment includes a main body member 41 fixed to the underside Da of the overhead sliding door D, and a holder member 42 that guides the second member 23 of the guide pin 2 into the groove portion 31 of the guide groove 3 by using magnetic force to protrude from the floor surface F.

[0025] In the present embodiment, the holder member 42 has a lower end surface 42a, when viewed from the door thickness direction y, which is an inclined surface whose height in the up-down direction z increases toward the guide groove 3. Such a guide device 1 can gradually protrude the second member 23 of the guide pin 2 in the upward direction z1 along the lower end surface 42a of the holder member 42 as the upper hung sliding door D moves in the closing direction x1, and guide the second member 23 to a height where it can engage with the groove portion 31 of the guide groove 3.

[0026] The holder member 42 is disposed on the main body member 41 so as to be slidable in the vertical direction z, for example. Such a guide device 1 has a large tolerance for the distance between the floor surface F and the upper hung sliding door D in the vertical direction z, and can guide the upper hung sliding door D even if the distance varies depending on the construction state of the installation position of the upper hung sliding door D. Furthermore, 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 contact state, thereby suppressing damage. Note that the guide receiver 4 may be formed integrally with the main body member 41 and the holder member 42.

[0027] Fig. 4 is an exploded perspective view of the guide receiver 4. As shown in Fig. 2 to Fig. 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 suspended sliding door D. The recess 43 may penetrate in the up-down direction z, for example, in a separate state before being fixed to the lower surface Da of the upper suspended sliding door D.

[0028] The holder member 42 of this embodiment is disposed in a recess 43. Such a recess 43 can accommodate the holder member 42 so as to be slidable in the up-down direction z. Note that even when the main body member 41 and the holder member 42 are integrally formed, the holder member 42 is provided inside the recess 43.

[0029] Fig. 5 is a perspective view of the guide device 1 when viewed from the downward direction z2, and Fig. 6 is a bottom view of the guide device 1 when viewed from the downward direction z2. As shown in Figs. 5 and 6, the maximum width W1 in the door thickness direction y of the first member 22 of the guide pin 2 is larger than the width W2 in the door thickness direction y of the recess 43 of the main body member 41. In such a guide device 1, even if the first member 22 protrudes to a position where it contacts the main body member 41, there is no risk that the first member 22 will enter the recess 43 of the main body member 41. Therefore, the guide device 1 of this embodiment can suppress damage caused by contact when the upper hanging sliding door D moves.

[0030] Fig. 7 is an exploded perspective view of the guide pin 2. As shown in Fig. 7, in a more preferred embodiment, the first member 22 includes a first shaft portion 22a movably held by the fixed member 21, and a first apex portion 22b formed on the upper end of the first shaft portion 22a. The first shaft portion 22a is formed, for example, in a substantially cylindrical shape. The first apex portion 22b is formed, for example, in a substantially disc shape. It is desirable that the first shaft portion 22a and the first apex portion 22b are formed coaxially.

[0031] In this embodiment, the width W1 of the first apex 22b in the door thickness direction y is larger than the width W3 of the first shaft portion 22a in the door thickness direction y. The width W1 of the first apex 22b corresponds to, for example, the diameter of the first apex 22b. The width W3 of the first shaft portion 22a corresponds to, for example, the diameter of the first shaft portion 22a. The maximum width W1 of the first member 22 in this embodiment corresponds to the width W1 of the first apex 22b, i.e., the diameter of the first apex 22b.

[0032] When such a first member 22 is accommodated within floor surface F, the gap between first shaft portion 22a and fixed member 21 can be covered by first apex 22b, thereby preventing foreign matter from getting caught in the gap between first shaft portion 22a and fixed member 21. Note that, for example, the diameter of first shaft portion 22a and the diameter of first apex 22b of first member 22 may be the same.

[0033] It is desirable that the maximum width W4 of the second member 23 in the door thickness direction y is smaller than the width W3 of the first shaft portion 22a in the door thickness direction y. Such a guide pin 2 is useful for reducing the weight of the second member 23 that protrudes the most, and also provides good stability when the first shaft portion 22a protrudes.

[0034] The second member 23 preferably includes a second shaft portion 23a movably held by the first member 22, and a second apex portion 23b formed at the upper end of the second shaft portion 23a. The second shaft portion 23a is formed, for example, in a substantially cylindrical shape. The second apex portion 23b is formed, for example, in a substantially disc shape. The second shaft portion 23a and the second apex portion 23b are preferably formed coaxially.

[0035] In this embodiment, the width W4 of the second apex 23b in the door thickness direction y is larger than the width W5 of the second shaft portion 23a in the door thickness direction y. The width W4 of the second apex 23b corresponds to, for example, the diameter of the second apex 23b. The width W5 of the second shaft portion 23a corresponds to, for example, the diameter of the second shaft portion 23a. The maximum width W4 of the second member 23 in this embodiment corresponds to the width W4 of the second apex 23b, i.e., the diameter of the second apex 23b.

[0036] When such second member 23 engages with guide groove 3, there is no risk of second apex 23b slipping out of guide groove 3, and it can stably guide upper hung sliding door D. Furthermore, when second member 23 is housed within first member 22, it can cover the gap between second shaft portion 23a and first member 22 with second apex 23b, so that it is possible to prevent foreign matter from getting caught in the gap between second shaft portion 23a and first member 22.

[0037] Fig. 8 is a side view of the guide device 1 when viewed from the closing direction x1. As shown in Fig. 8, the width W4 of the second top portion 23b, which is the maximum width W4 in the door thickness direction y of the second member 23 of the guide pin 2, is preferably smaller than the width W6 in the door thickness direction y of the holder member 42. Such a guide device 1 has a large tolerance for misalignment between the holder member 42 and the guide pin 2 in the door thickness direction y.

[0038] The holder member 42 has a concave curved surface in which the lower end surface 42a is concave in the upward direction z1 when viewed from the opening / closing direction x, for example. When the guide pin 2 is protruded from the holder member 42, a magnetic force acts on the holder member 42 to direct the guide pin 2 toward the center of the concave curved surface, so that the center positions of the holder member 42 and the guide pin 2 in the door thickness direction y can be aligned.

[0039] The guide pin 2 desirably has a top surface 2a that comes into contact with the holder member 42 and is a convex curved surface that is convex in the upward direction z1. The top surface 2a of the guide pin 2 that comes into contact with the holder member 42 is desirably formed on the second apex 23b. The radius of curvature R1 of the convex curved surface of the guide pin 2 in this embodiment is smaller than the radius of curvature R2 of the concave curved surface of the holder member 42. Such a guide device 1 can efficiently apply a force toward the center of the concave curved surface, and can more reliably align the central positions of the holder member 42 and the guide pin 2 in the door thickness direction y.

[0040] 7, the fixing member 21 of the guide pin 2 of this embodiment includes a substantially cylindrical fixing shaft portion 21b having a fixing hole 21a extending in the up-down direction z. The fixing member 21 desirably includes a substantially cylindrical case portion 24 that covers the periphery of the fixing shaft portion 21b. The case portion 24 has, for example, a case hole 24a in which the fixing shaft portion 21b is disposed.

[0041] The fixed shaft portion 21b is formed of, for example, resin or non-magnetic metal. When the fixed shaft portion 21b is formed of resin, it is preferable to select from polyacetal, polyamide, etc. The resin of the fixed shaft portion 21b may contain, for example, reinforcing fiber. When the fixed shaft portion 21b is formed of a non-magnetic metal, it is preferable to select from titanium, aluminum, etc.

[0042] The case portion 24 is formed of, for example, a resin or a non-magnetic metal. When the case portion 24 is formed of a resin, it is preferable to select from polyacetal, polyamide, etc. The resin of the case portion 24 may contain, for example, reinforced fibers. When the case portion 24 is formed of a non-magnetic metal, it is preferable to select from titanium, aluminum, etc. The case portion 24 may be formed of the same material as the fixed shaft portion 21b, or may be formed of a different material.

[0043] When the guide pin 2 is installed inside a floor surface F, for example, the case portion 24 is first placed in an attachment hole formed in the floor surface F. Then, it is desirable that the fixed shaft portion 21b, the first member 22, and the second member 23 are pre-assembled and then fitted into the case hole 24a of the case portion 24. Such a guide pin 2 can be easily installed on the floor surface F, improving work efficiency.

[0044] It is preferable that the case part 24 of the fixed member 21 is fixed to the floor surface F so as to be unrotatable and unmovable in the vertical direction z. It is preferable that the fixed shaft part 21b is fixed to the case part 24 so as to be unrotatable and unmovable in the vertical direction z. Such a fixed member 21 can suppress fluctuations in the orientation of the guide pin 2, and can firmly maintain the fixed state even when an external force acts on the guide pin 2. Note that the fixed member 21 may be formed such that the fixed shaft part 21b and the case part 24 are integrally formed, for example.

[0045] In this embodiment, the first shaft portion 22a of the first member 22 is arranged in the fixing hole 21a of the fixed shaft portion 21b so as to be movable in the vertical direction z. It is preferable that the first shaft portion 22a is arranged so as not to be rotatable relative to the fixing hole 21a. Such a first member 22 does not rotate even when an external force acts on the guide pin 2, and can move smoothly in the vertical direction z relative to the fixed member 21.

[0046] The first member 22 desirably has a first hole 22c for holding the second member 23. In this embodiment, the first hole 22c is provided at a position offset from the center position of the first shaft portion 22a. Even if the mounting hole formed in the floor surface F is misaligned in the door thickness direction y, such a guide pin 2 can be accommodated by adjusting the mounting angle of the first member 22 to the fixing hole 21a.

[0047] The first member 22 is formed from, for example, a resin or a non-magnetic metal. When the first member 22 is formed from a resin, it is preferable to select from polyacetal, polyamide, etc. The resin of the first member 22 may contain, for example, reinforcing fibers. When the first member 22 is formed from a non-magnetic metal, it is preferable to select from titanium, aluminum, etc.

[0048] The second shaft portion 23a of the second member 23 in this embodiment is disposed in the first hole 22c of the first member 22 so as to be movable in the up-down direction z. The second member 23 is formed of, for example, a magnetic material. The second member 23 in this embodiment is made of iron. For example, a washer 25 engages with a second groove 23c provided at the lower end of the second shaft portion 23a to prevent the second member 23 from slipping out of the first hole 22c. Such a second member 23 is suitable for protruding in the upward direction z1 by the magnetic force of the holder member 42.

[0049] 2 and 3, the main body member 41 has, for example, a first sliding portion 44A extending in the vertical direction z on the guide groove 3 side in the opening / closing direction x of the main body member 41, and a second sliding portion 44B extending in the vertical direction z on the opposite side. Such first sliding portion 44A and second sliding portion 44B are useful for maintaining the posture of the holder member 42 when the holder member 42 moves in the vertical direction z.

[0050] 4, it is preferable that the main body member 41 has at least one engagement portion 45 that engages with the guide groove 3. Such an engagement portion 45 serves to suppress misalignment and rattling with the guide groove 3 and facilitate the connection work between the guide receiver 4 and the guide groove 3.

[0051] 2 to 4, the main body member 41 of this embodiment has a guide portion 51 formed at the lower end of the recess 43 and positioned below the second apex 23b when guiding the second member 23 into the guide groove 3. Such a guide portion 51 can guide the guide pin 2 into the guide groove 3 as long as the second apex 23b of the second member 23 protrudes from the first member 22 even when the first member 22 and the second member 23 are temporarily fixed to each other.

[0052] It is desirable that the guide portion 51 protrudes at an acute angle from the guide groove 3 side toward the inside of the recess 43 at the lower end of the main body member 41. Such a guide portion 51 can guide the guide pin 2 into the guide groove 3 even if the amount of protrusion of the second apex 23b from the first member 22 is small.

[0053] The guide portion 51 of this embodiment has a push-down portion 51a that protrudes in the downward direction z2. Such a push-down portion 51a can contact the first apex 22b of the guide pin 2 and push down the first member 22 in the downward direction z2. Therefore, the guide device 1 of this embodiment can also push down the second member 23 when the first member 22 and the second member 23 are temporarily fixed to each other. As a result, the guide device 1 of this embodiment can suppress damage caused by contact between the second apex 23b and the guide portion 51 even when the second apex 23b of the second member 23 does not protrude sufficiently from the first member 22.

[0054] The main body member 41 is formed, for example, from a resin or a non-magnetic metal. When the main body member 41 is formed from a resin, it is preferable to select from polyacetal, polyamide, etc. The resin of the main body member 41 may contain, for example, reinforced fibers. When the main body member 41 is formed from a non-magnetic metal, it is preferable to select from titanium, aluminum, etc. Such a main body member 41 is not affected by magnetic force and can be easily processed into a complex shape.

[0055] The holder member 42 of the present embodiment includes a holder main body 46 constituting the lower end surface 42a, and a magnet 47 housed in the holder main body 46. The magnet 47 desirably includes a first magnet 47A housed on the guide groove 3 side in the opening / closing direction x of the main body member 41, and a second magnet 47B housed adjacent to the first magnet 47A and away from the guide groove 3.

[0056] It is desirable that the second magnet 47B has a stronger magnetic force than the first magnet 47A. The first magnet 47A is, for example, a ferrite magnet. The second magnet 47B is, for example, a neodymium magnet. With such a magnet 47, even if the magnet 47 is far away from the guide pin 2, the strong magnetic force of the second magnet 47B can reliably cause the second member 23 of the guide pin 2 to protrude.

[0057] The holder body 46 is formed, for example, from a resin or a non-magnetic metal. When the holder body 46 is formed from a resin, it is preferable to select from polyacetal, polyamide, etc. The resin of the holder body 46 may contain, for example, reinforced fibers. When the holder body 46 is formed from a non-magnetic metal, it is preferable to select from titanium, aluminum, etc. Such a holder body 46 is not affected by magnetic force and slides smoothly within the recess 43 of the main body member 41.

[0058] The holder body 46 includes, for example, a first protrusion 48A that moves within the first sliding portion 44A and a second protrusion 48B that moves within the second sliding portion 44B. Such first protrusion 48A and second protrusion 48B are useful for maintaining the posture of the holder member 42 while reducing friction with the first sliding portion 44A and the second sliding portion 44B, respectively.

[0059] 4, it is preferable that the holder body 46 of the holder member 42 has a plurality of protrusions 49 that contact the recesses 43 of the main body member 41. The protrusions 49 extend, for example, in the up-down direction z. Such protrusions 49 reduce the contact area between the holder member 42 and the main body member 41, thereby helping to maintain the posture of the holder member 42 while reducing friction with the main body member 41. Therefore, the holder member 42 of this embodiment can smoothly slide in the up-down direction z inside the main body member 41 in a stable posture.

[0060] 2 and 3, the holder body 46 has, for example, a first holding portion 50A for holding the first magnet 47A and a second holding portion 50B for holding the second magnet 47B. In this embodiment, the first holding portion 50A and the second holding portion 50B are each provided in pairs in the door thickness direction y. Such first holding portion 50A and second holding portion 50B can reliably hold the magnet 47 even when the holder member 42 moves violently inside the main body member 41.

[0061] In the above embodiment, the guide device 1 is provided on the closing direction x1 side of the guide groove 3, but it may also be provided on the opening direction x2 side of the guide groove 3. Also, it is sufficient that at least one guide pin 2 is provided on the floor surface F, and multiple guide pins 2 may be provided.

[0062] In the above embodiment, the first shaft portion 22a of the first member 22 is formed in a substantially cylindrical shape, and the first top portion 22b is formed in a substantially disk shape, but the first member 22 is not limited to such a shape. As the cross-sectional shape parallel to the floor surface F of the first member 22, various shapes such as an elliptical shape, a polygonal shape, a sector shape, etc. may be adopted. Similarly to the first member 22, various shapes may be adopted for the cross-sectional shape parallel to the floor surface F of the second member 23.

[0063] In addition, in the above-described embodiment, the second member 23 of the guide pin 2 is formed of a magnetic material, and a magnet 47 is provided on the holder member 42 of the guide receiver 4, but a magnet may be provided on the second member 23 of the guide pin 2, and the holder member 42 may be formed of a magnetic material.

[0064] Although a particularly preferred embodiment of the present invention has been described in detail above, the present invention is not limited to the above-described embodiment and can be modified in various ways. [Explanation of symbols]
