Description

This disclosure relates to a multiple sliding door.

Conventionally, a top-hung multiple sliding door with multiple movable door bodies has been known (see, for example, Patent Document 1).

The multiple sliding door described in Patent Document 1 includes two door bodies, a first sliding door and a second sliding door, each of which is movably suspended and supported by a rail fixed to a ceiling. A guide body is fixed to the lower end of the vertical frame of the second sliding door. The guide body includes a guide fixing part, a guide beam part, and a guide support part, and is attached to the sliding door by bolting the guide fixing part to the lower end side surface of the vertical frame. The guide support portion at the tip of the guide body extends toward the first sliding door and is inserted from below into a guide recess provided in the lower end surface of the frame of the first sliding door. As a result, when the guide body of the second sliding door comes into contact with the end of the guide recess of the first sliding door while the first sliding door moves in the opening and closing directions, the second sliding door will move in conjunction with the movement of the first sliding door. and move in the opening and closing directions. When the opening is fully opened, the first sliding door and the second sliding door are arranged overlapping each other over the entirety, so there is no remaining opening.

Utility model registration No. 3190349

However, in conventional multi-sliding doors, the guide body is fixed to the bottom side of the vertical frame, so if the bottom frame of the frame is made thinner, if the surface material to be housed in the frame is glass, one side The guide body of the other sliding door is completely visible through the glass of the sliding door, resulting in a poor appearance. Furthermore, if the vertical frame is made thinner, it becomes difficult to attach the guide body itself.

Thus, while conventional multiple sliding doors have the advantage of being able to reduce the distance between adjacent door bodies, they also have the problem that when door bodies with narrower frames and larger glass areas are used, the appearance deteriorates and it becomes difficult to attach the guide body.

The purpose of this disclosure is to enable adjacent door bodies in a top-hung multiple sliding door to be linked together without compromising the appearance.

The present disclosure relates to a multiple sliding door having at least two door bodies suspended from above so as to be movable in the sight direction, the two door bodies being a first door body movable in the sight direction and a second door body movable in the sight direction in conjunction with the movement of the first door body, each having a guide groove extending in the sight direction on its lower end surface, the second door body having a connecting guide member fixed to the end of the lower end surface on the side of the first door body of the linkage origin in the sight direction, the connecting guide member having a fixed plate portion fixed to the lower end surface of the second door body, a guide plate portion extending from the fixed plate portion downwardly of the guide groove of the first door body of the linkage origin, and a guide pin protruding from the upper surface of the guide plate portion and fitting into the guide groove of the first door body of the linkage origin, a step is provided between the fixed plate portion and the guide plate portion, and the fixed plate portion is positioned above the position of the guide plate portion via the step.

The direction indicated by X1-X2 is the direction passing through the opening 100 and indicates the "looking direction" of the multiple sliding door 1. The direction indicated by Y1-Y2 is the direction of movement of the leading door body 3, the intermediate driven door body 4, and the trailing driven door body 5 when opening and closing, and indicates the "finding direction" of the multiple sliding door 1. Y1 indicates the "closing direction" and the "door end side" of the leading door body 3, the intermediate driven door body 4, and the rear driven door body 5. Y2 indicates the "opening direction" and "door tail side" of the leading door body 3, the intermediate driven door body 4, and the rear driven door body 5. The direction indicated by Z1-Z2 is the vertical direction of the multiple sliding door 1. Z1 indicates "upward" and Z2 indicates "downward".

The upper frame 21 and lower frame 22 of this embodiment are formed longer than the width of the opening 100. Therefore, when the multiple sliding door 1 is viewed from one of the two rooms connected by the opening 100, a wall section 200 having an area roughly equivalent to that of one door body is facing the vertical frame 24 side on the inside of the frame body 2. The leading door body 3, the intermediate driven door body 4, and the trailing driven door body 5 are accommodated so as to overlap this wall section 200 when they move toward the vertical frame 24 side to fully open the opening 100.

As shown in FIG. 2, on the lower surface 21a of the upper frame 21, three rails 25 that independently suspend and support the leading door body 3, intermediate driven door body 4, and rear driven door body 5 are provided with a plurality of mounting screws. 26. The three rails 25 are arranged in parallel in the viewing direction and extend over the entire length of the upper frame 21 in the longitudinal direction. In the perspective direction of the upper frame 21 to which the rail 25 is fixed, a side decorative board 27 for concealing the rail 25 is attached to the X2 side opposite to the wall portion 200. A lower surface decorative plate 28 is attached to the lower surface side of the rail 25 for shielding each of the leading door body 3, the intermediate driven door body 4, and the rear driven door body 5 while leaving openings for movement thereof.

As shown in FIG. 2, the leading door body 3, the intermediate driven door body 4, and the rear driven door body 5 are arranged adjacent to each other in the viewing direction. The leading door body 3 is arranged on the X2 side which is farthest from the wall portion 200 among the three door bodies in the viewing direction. The rear driven door body 5 is arranged on the X1 side closest to the wall portion 200 among the three door bodies in the viewing direction. The intermediate driven door body 4 is arranged between the leading door body 3 and the rear driven door body 5 in the viewing direction.

As shown in FIG. 1, the leading door body 3 is a door body on the leading side when moving in the closing direction toward the vertical frame 23. The intermediate driven door body 4 is disposed adjacent to the trailing end side of the leading door body 3 when the opening 100 is fully closed. The leading door body 3 is a door body that links with the intermediate driven door body 4. In this embodiment, the leading door body 3 corresponds to the "first door body". The intermediate driven door body 5 is disposed adjacent to the trailing end side of the intermediate driven door body 4 when the opening 100 is fully closed, and closes the gap between the intermediate driven door body 4 and the wall portion 200. The intermediate driven door body 4 is a door body that links with the trailing driven door body 5. In this embodiment, the intermediate driven door body 4 corresponds to the "second door body". However, the "first door body" may be a door body that links with the "second door body". Therefore, in the case of having three door bodies as in this embodiment, the middle driven door body 4 may be the "first door body" and the rear driven door body 5 may be the "second door body."

First, the leading door body 3 will be described with reference to Figures 3 to 6. As shown in Figure 3, the leading door body 3 is constructed by fitting a surface material 35 inside a frame body 30 in which an upper rail 31, a lower rail 32, a vertical frame 33 on the door front side, and a vertical frame 34 on the door rear side are assembled into a rectangular frame. A pair of hoisting wheels 36 are attached to the upper rail 31. The pair of hoisting wheels 36 attached to the leading door body 3 of this embodiment are both normal hoisting wheels, but at least one of the pair of hoisting wheels 36 may be a hoisting wheel with a soft motion member that has a function of decelerating near the end of the movement. As shown in Figure 2, the leading door body 3 is suspended from above so that it can move along the rail 25 in the direction of sight by the pair of hoisting wheels 36 being rollably accommodated within the rail 25. A handle 37 is provided on the surface of the surface material 35 for holding the hand when opening and closing the leading door body 3. In this embodiment, the handles 37 are placed on both the front and back sides of the panel 35 near the vertical frame 33 on the door end side. However, the position and shape of the handles 37 are optional and are not limited to those shown in the figure. The leading door body 3 does not necessarily have to have a handle.

As shown in Figures 4 to 6, a pair of guide protrusions 321 extending in the viewing direction protrude downward at a predetermined height H0 on the lower end surface 32a (lower surface of the lower rail 32) of the leading door body 3. The guide protrusions 321 are formed in a U-shaped cross section with a groove 321a on the inside. The guide protrusions 321 are integrally molded with the lower rail 32 from a metal material such as aluminum. The pair of guide protrusions 321 are arranged parallel to each other with a gap between them, with the grooves 321a facing each other. The grooves 321a are open at both ends of the lower rail 32 in the longitudinal direction.

A guide rail 322 is accommodated between the pair of guide protrusions 321 along the length direction of the guide protrusions 321 . The guide rail 322 is made of a resin material with good sliding properties and is formed in the shape of a gutter that opens downward. A guide groove 323 extending in the finding direction is formed in the lower end surface 32a of the leading door body 3 by the opening of the guide rail 322. A recess 324 is formed between the pair of guide protrusions 321 and extends over the entire length of the lower crosspiece 32 in the longitudinal direction. The guide rail 322 is disposed between the pair of guide protrusions 321 and fitted into the groove 321a and the recess 324.

The length of the pair of guide protrusions 321 in the finding direction is shorter than the entire length of the lower crosspiece 32. Therefore, end regions 32b in which the guide protrusions 321 are not formed are provided at both ends of the lower crosspiece 32 in the finding direction. A door tip piece 6 and a door bottom end piece 7 that close both ends of the guide groove 323 are attached to each end region 32b.

The door tip piece 6 is disposed on the door tip side of the lower rail 32 of the leading door body 3. As shown in FIG. 5, the door tip piece 6 includes a spacer 61, a lower piece member 62, and a stopper member 63.

The spacer 61 is made of a metal plate such as aluminum. The spacer 61 is formed into a substantially rectangular shape that is longer in the viewing direction than in the finding direction. A notch 61a having substantially the same width as the guide groove 323 is formed on the side edge of the spacer 61 disposed on the guide groove 323 side. A pair of screw through holes 61b are formed in the spacer 61 and are spaced apart from each other in the viewing direction.

The lower piece member 62 is disposed on the underside of the spacer 61. The lower piece member 62 is formed of a metal plate material such as aluminum, and is approximately the same size as the spacer 61. The lower piece member 62 has a rectangular cutout portion 62a that is cut out significantly in the view direction from the guide groove 323 side. The cutout portion 62a has approximately the same width as the guide groove 323, and is cut out deeper in the view direction than the cutout portion 61a of the spacer 61. The lower piece member 62 has a pair of screw through holes 62b that are spaced apart in the view direction. A rising portion 62c that extends upward is formed on the side edge of the lower piece member 62 opposite the guide groove 323. The rising portion 62c is formed over the entire length of the lower piece member 62 in the view direction.

The stopper member 63 is a member that elastically abuts against a guide pin (described later) provided on the intermediate driven door body 4 when the leading door body 3 is moved in the closing direction. The stopper member 63 has a thickness approximately equal to the depth of the guide groove 323, and is formed in a block shape that is long in the front direction from an elastic material such as rubber. A groove 63a is formed on the outer end face of the stopper member 63 in the front direction into which the spacer 61 is inserted and clamped. A protrusion 63b that protrudes in the front direction is integrally formed on both sides of the stopper member 63 in the front direction. The width of the stopper member 63 in the front direction, including the pair of protrusions 63b, is slightly larger than the width of the guide groove 323.

The stopper member 63 is housed in the guide groove 323 by inserting the spacer 61 into the groove 63a from the notch 61a side and sandwiching the spacer 61 from above and below. In the door tip piece 6, the spacer 61 and the lower piece member 62, which are sandwiched by the stopper member 63, are screwed together into the pair of screw holes 325 of the lower crosspiece 32 by fixing screws SC passing through the screw through holes 61b and 62b. It is fixed to the end region 32b by being tightened. The stopper member 63 is sandwiched between the spacer 61 and the recess 324 of the lower crosspiece 32, and is held within the guide groove 323 by elastically deforming the protrusion 63b within the guide groove 323. The rising portion 62c of the lower piece member 62 covers the outer side edge of the spacer 61 in the finding direction. The lower surface 62d of the lower piece member 62 of the door tip piece 6 fixed to the lower crosspiece 32 and the lower surface 63c of the stopper member 63 are arranged substantially flush with the lower surface 321b of the guide protrusion 321. The width of the door tip piece 6 in the projected direction is approximately the same as the width of the entire pair of guide protrusions 321 of the lower crosspiece 32 in the projected direction.

The tail end piece 7 is disposed on the tail side of the lower rail 32 of the leading door body 3. As shown in FIG. 6, the tail end piece 7 includes a spacer 71, a lower piece member 72, and a stopper member 73.

The spacer 71 and the lower piece member 72 have the same configuration as the spacer 61 and the lower piece member 62 of the door tip piece 6. That is, the spacer 71 has a notch portion 71a and a pair of screw through holes 71b. The lower piece member 72 has a notch portion 72a, a pair of screw through holes 72b, and a rising portion 72c.

The stopper member 73 is a member that elastically abuts a guide pin provided on the intermediate driven door body 4, which will be described later, when the leading door body 3 is moved in the opening direction. The stopper member 73 has the same configuration as the stopper member 63 except that it does not have the convex portion 63b that the stopper member 63 in the door tip piece 6 has and that the length in the finding direction is shorter than the stopper member 63. It is. That is, a groove 73a into which the spacer 71 is inserted and held is formed on the outer end surface of the stopper member 73 in the finding direction. The length of the stopper member 73 in the finding direction is approximately the same as the length of the end region 32b in the finding direction.

The trailing edge piece 7, like the leading edge piece 6, is fixed to the end region 32b by fastening the spacer 71 and the lower piece member 72, which are sandwiched between the stopper member 73, together with a pair of screw holes 325 in the lower rail 32 with a pair of fixing screws SC. The stopper member 73 is not accommodated in the guide groove 323 because its length in the visible direction is shorter than that of the stopper member 63. The lower surface 72d of the lower piece member 72 of the trailing edge piece 7 fixed to the lower rail 32 and the lower surface 73b of the stopper member 73 are arranged approximately flush with the lower surface 321b of the guide protrusion 321. The width of the trailing edge piece 7 in the visible direction is approximately the same as the overall width in the visible direction of the pair of guide protrusions 321 of the lower rail 32.

Next, the intermediate driven door body 4 and the rear driven door body 5 will be explained with reference to FIGS. 7 to 9. The intermediate driven door body 4 and the rear driven door body 5 have substantially the same configuration. Therefore, FIGS. 7 to 9 are commonly used for the intermediate driven door body 4 and the rear driven door body 5, and the constituent parts of the intermediate driven door body 4 are marked with the number "4" at the beginning. The constituent parts of the body 5 will be described with reference numerals beginning with "5".

As shown in FIG. 7, the intermediate driven door body 4 and the rear driven door body 5 include upper bars 41, 51, lower bars 42, 52, vertical stile 43, 53 on the door end side, vertical stile 44 on the door end side, It is constructed by storing the face materials 45, 55 inside the frame bodies 40, 50 which are made by assembling frames 40, 54 into a rectangular shape. A pair of hanging wheels 46, 56 are attached to the upper bars 41, 42. The pair of hanging wheels 46, 56 attached to the intermediate driven door body 4 and the rear driven door body 5 of this embodiment both use normal hanging wheels, but at least one of the pair of hanging wheels 46, 56 is used. may be a hanging wheel with a soft motion member that has the function of decelerating near the end of travel. As shown in FIG. 2, the intermediate driven door body 4 and the rear driven door body 5 have a pair of hanging wheels 46, 56 rotatably housed in the rail 25, similarly to the leading door body 3. It is suspended above so as to be movable in the finding direction along the rail 25. The handle 37 provided on the leading door body 3 is not provided on the intermediate driven door body 4 and the rear driven door body 5.

In the multiple sliding door 1 of the present disclosure, the panel materials 35, 45, 55 housed in each door body 3, 4, 5 may be opaque board materials such as wood panels, or may be transparent or translucent. It may be a glass plate. Since the frames 30, 40, 50 of this embodiment are thin, the frames 30, 40, 50 are not noticeable. Therefore, especially when the face materials 35, 45, and 55 are made of transparent glass plates, a wide amount of daylight can be secured even when the opening 100 is completely closed, and the multiple sliding door 1 has a good design. be able to.

As shown in FIGS. 8 and 9, the lower end surfaces 42a and 52a (lower surfaces of the lower crosspieces 42 and 52) of the intermediate driven door body 4 and the rear driven door body 5 include the guide protrusion 321 of the leading door body 3 and the guide convex portion 321 of the leading door body 3, Guide protrusions 421, 521, guide rails 422, 522, guide grooves 423, 523, and recesses 424, 524 having the same configuration as the rail 322, guide groove 323, and recess 324 are provided. The guide protrusions 421 and 521, like the guide protrusion 321 of the first door body 3, have grooves 421a and 521a that open at both ends of the lower crosspieces 42 and 52 in the length direction, respectively. End areas 42b and 52b in which guide protrusions 421 and 521 are not formed are provided at both ends of the lower crosspieces 42 and 52 in the finding direction, respectively.

There is. The width of the door tip piece 8 excluding the connecting guide member 81 in the expected direction is approximately the same as the width of the entire pair of guide protrusions 421, 521 of the lower crosspieces 42, 52 in the expected direction.

The guide pins 814 of the door tip pieces 8 attached to the bottom rail 42 of the intermediate driven door body 4 and the bottom rail 52 of the trailing driven door body 5, respectively, fit into the guide grooves 323 of the adjacent leading door body 3 and the guide grooves 423 of the intermediate driven door body 4, as shown in Figures 12 to 14. A regulating guide pin 9 arranged on the upper surface 22a of the lower frame 22 fits into the guide groove 523 of the trailing driven door body 5. The regulating guide pin 9 is fixed by a screw 91 to the upper surface 22a of the lower frame 22 near the boundary between the opening 100 and the wall portion 200.

Next, the operation of the multiple sliding door 1 will be explained. When the leading door body 3 is moved toward the vertical frame 23 on the door end side with the opening 100 fully opened, the guide pin 814 of the intermediate driven door body 4 will eventually move to the door end piece of the leading door body 3. It abuts against the stopper portion 73 of No. 7. Thereby, the intermediate driven door body 4 moves toward the vertical frame 23 in conjunction with the movement of the leading door body 3. When the intermediate driven door body 4 moves, the guide pin 814 of the rear driven door body 5 eventually comes into contact with the stopper portion 73 of the door end piece 7 of the intermediate driven door body 4. As a result, the rear driven door body 5 moves toward the vertical frame 23 in conjunction with the movement of the intermediate door body 4. When the leading door body 3 comes into contact with the vertical frame 23 and the regulating guide pin 9 of the lower frame 22 comes into contact with the stopper part 73 of the door end piece 7 of the trailing driven door body 5, as shown in FIG. The leading door body 3, the intermediate driven door body 4, and the rear driven door body 5 completely close the opening 100.

When the leading door body 3 is moved toward the vertical frame 24 on the door tail side with the opening 100 fully closed, the guide pin 814 of the intermediate driven door body 4 eventually comes into contact with the stopper member 63 of the door tip piece 6 of the leading door body 3. As a result, the intermediate driven door body 4 moves toward the vertical frame 24 in conjunction with the movement of the leading door body 3. As the intermediate driven door body 4 moves, the guide pin 814 of the trailing driven door body 5 eventually comes into contact with the stopper portion 83 of the door tip piece 8 of the intermediate driven door body 4. As a result, the trailing driven door body 5 moves toward the vertical frame 24 in conjunction with the movement of the intermediate driven door body 4. When the regulating guide pin 9 of the lower frame 22 abuts against the stopper portion 83 of the door tip piece 8 of the rear driven door body 5, the leading door body 3, the intermediate driven door body 4, and the rear driven door body 5 are accommodated so as to overlap with the wall portion 200, as shown in FIG. 13, and the opening 100 is fully opened. If the hoist 36, 46, 56 is equipped with a soft motion member, the leading door body 3, the intermediate driven door body 4, and the rear driven door body 5 decelerate just before the stopper portion 83 of the door tip piece 8 of the rear driven door body 5 abuts against the regulating guide pin 9 of the lower frame 22, so they are accommodated while moving slowly to the specified position.

As shown in FIG. 13, when the opening 100 is fully opened and the leading door body 3, intermediate driven door body 4, and rear driven door body 5 overlap, the connecting guide member at the door tip piece 8 of the trailing driven door body 5 The guide plate portion 813 of 81 is arranged so as to overlap below the door tip piece 8 of the intermediate driven door body 4.

It is arranged so as to cover a part of the lower piece member 82 in the door tip piece 8 of the intermediate driven door body 4 from below without interfering with it. As a result, the remaining dimension L10 between the intermediate driven door body 4 and the rear driven door body 5 is set as small as possible.

The length of the stopper member 63 in the door tip piece 6 of the leading door body 3 in the finding direction is longer than the length of the stopper part 83 in the door tip piece 8 of the intermediate driven door body 4 and the rear driven door body 5 in the finding direction. long. Therefore, when the guide pin 814 of the intermediate driven door body 4 is in contact with the stopper member 63 of the leading door body 3, the position of the intermediate driven door body 4 on the door end side is higher than the handle 37 of the leading door body 3. It is placed on the door end side of the body 3. At this time, the remaining length L20 between the leading door body 3 and the intermediate driven door body 4 is set to be larger than the remaining length L10 between the intermediate driven door body 4 and the trailing driven door body 5. This remaining length L20 is set to a safe dimension that allows the operator to operate the handle 37 of the leading door body 3 and prevents fingers from being caught. As described above, the remaining length L10 between the intermediate driven door body 4 and the rear driven door body 5 is set as small as possible, so the overall remaining length L10+L20 of the multiple sliding door 1 is small. Therefore, according to this multiple sliding door 1, a wide opening area of the opening 100 can be ensured.

When the guide pins 814 of the door tip pieces 8 of the intermediate driven door body 4 and the rear driven door body 5 come into contact with the stopper members 63, 73, 83 of the leading door body 3 and the intermediate driven door body 4, the connecting guide member 81 As shown in FIG. 9, a stress F along the finding direction is applied. This stress F is a force in a direction that rotates the connecting guide member 81 along the lower end surfaces 42a, 52a of the lower crosspieces 42, 52. When the connecting guide member 81 rotates, there is a possibility that the fixed state may become loose. On the other hand, the fixing plate portion 811 of the connecting guide member 81 is attached by inserting the protruding portion 811c into the groove portions 421a, 521a of the guide convex portions 421, 521 of the lower crosspieces 42, 52. Even if the stress F acts on the member 81, the projections 811c inserted into the grooves 421a and 521a prevent the connection guide member 81 from rotating. Therefore, the fixed state of the connecting guide member 81 does not become loose.

To prevent the connecting guide member 81 from rotating when stress F is applied, as shown in FIG. 15, a pair of protruding walls 815 that hold the lower rails 32, 42 of the adjacent leading door body 3 and intermediate driven door body 4 in the forward direction may be provided on the upper surface 813a of the guide plate portion 813 of the connecting guide member 81.
