Description

  The present invention relates to a sliding door device excellent in design used especially for an entrance and exit of an office.

In consideration of design, there is a sliding door device in which the surface plate of the maintenance panel (inspection panel, rammer panel) is substantially flush with the front and rear surface plates of the closed sliding door (for example, Patent Document 1).
However, in the case of such a sliding door device, in order to prevent light leakage, a convex portion is provided at the upper portion of the sliding door, and the lower end portion of the maintenance panel is accommodated in a concave portion formed between the convex portion and the sliding door surface material. However, when the lower end of the maintenance panel is accommodated in the sliding door recess in this way, the clearance between the lower end of the maintenance panel and the protruding portion of the sliding door is small, and the lower end of the inspection panel or the rammer panel due to deformation or distortion of the maintenance panel. And the convex part of the sliding door may come into contact. Therefore, the generation of rubbing noise at the time of contact and the opening / closing resistance of the sliding door increase due to the contact, which may hinder the opening / closing of the sliding door.

JP2015-202111A

  The present invention provides a sliding door device in which the maintenance panel and the sliding door are not in direct contact with each other even if the surface plate of the maintenance panel is substantially flush with the front and rear surface plates of the closed sliding door. The issue is to provide.

  In order to solve the above-described problems, the present invention is configured as a first means. In the sliding door device that opens and closes the entrance / exit opening, the sliding door device includes at least a rail member, a door, and a maintenance panel that conceals the rail member portion. The upper end of the door is elongated in the opening and closing direction and is narrower than the thickness of the door. The lower end of the maintenance is accommodated in the recess formed by the convex and the surface of the door. In this case, at least one of the door and the maintenance panel is provided with a synthetic resin sliding body that prevents the projection of the door and the maintenance panel from coming into direct contact with each other.

  In order to solve the above-mentioned problems, the present invention is configured as a second means. In the sliding door device that opens and closes the entrance / exit opening, the sliding door device includes at least a rail member, a door, and a maintenance panel that conceals the rail member portion. The upper end of the door is elongated in the opening and closing direction and is narrower than the thickness of the door. The lower end of the maintenance is accommodated in the recess formed by the convex and the surface of the door. In this case, at least one of the door and the maintenance panel is provided with a rotating roller that prevents the convex portion of the door and the maintenance panel from directly contacting each other.

  According to the configuration as the first means, the sliding body comes into contact with the door or the maintenance panel before the convex portion of the door and the maintenance panel come into direct contact with each other. Since the sliding body is made of synthetic resin and has excellent sliding properties, the resistance when the sliding body and the door or maintenance panel come into contact can be reduced. Therefore, it is possible to prevent the opening and closing of the door from being hindered by the opening and closing resistance of the door which increases when the door and the maintenance panel come into contact with each other. Therefore, the gap between the door and the maintenance panel can be reduced.

  According to the configuration as the second means, the rotary roller comes into contact with the door or the maintenance panel first before the convex part of the door and the maintenance panel are in direct contact with each other. Since the rotating roller rotates, the rotating roller rotates when the rotating roller contacts the door or the maintenance panel, and the resistance at the time of contact decreases, and the door is opened and closed when the door is opened and closed. It is possible to prevent rubbing noise generated when the maintenance panel comes into contact with the door, and to prevent the door from being hindered by opening and closing resistance that increases when the door comes into contact with the maintenance panel. Therefore, the gap between the door and the maintenance panel can be reduced.

In addition, an L-shaped angle member 5 c is used in the lower part near the center of the rail holding member 5 and is fixed to the rail reinforcing member 2 to prevent the rail holding member 5 from swinging back and forth.

The rail member 50 has a shorter length than the rail holding member 5 and is arranged in the longitudinal direction of the rail member 50. As shown in FIG. 3, the rail member 50 has a substantially C-shaped cross section and is slightly shorter than the rail holding member 5. Rail-reinforcing member, an outer member having a substantially C-shaped cross-section that is screwed to the interior side of the rail-reinforcing member, a ball that is approximately the same length as the outer member, and a ball that is approximately two-thirds of the length of the outer member. It is composed of a moving member that is slidably held by the outer member via a ball that is rotatably held by the retainer. A hanging metal fitting 51 having a length approximately the same as that of the moving member is fixed.

As shown in FIG. 3, the hanging metal fitting 51 includes a connection fixing portion 52 that is fixed to the front surface side of the moving member, and a U-shaped suspension that opens on the front surface side that is connected to the lower end portion of the connection fixing portion 52. The lower support portion 53 is configured.
And the suspension bolt insertion hole which the front side opens is formed in the opening-closing direction side both ends of the suspension support part 53. As shown in FIG.

  The sliding door 6 suspended from the hanging bracket 51 includes a sliding door vertical frame 65 provided on the door end side, a sliding door upper frame 64 provided on the top of the sliding door 6, and a convex member attached to the upper surface of the sliding door upper frame 64. 7, a sliding door lower frame 66 provided at the lower part of the sliding door 6, and a paper honeycomb core 67 disposed in a space surrounded by the sliding door vertical frame 65, the sliding door upper frame 64, and the sliding door lower frame 66, The front surface and the rear surface of the internal structural member are formed into a panel shape by covering with the front plate 62 and the rear plate 63, and the upper cover 8 is covered from the upper surface of the convex member 7.

As shown in FIG. 3, a front recess 700 and a rear recess 701 are formed in the upper part of the sliding door 6, and the fitting groove 60 into which the guide roller 41 is fitted in the opening and closing direction of the lower end surface of the sliding door lower frame 66. The door end portion 600 is provided with a door stopper rubber 600 that is a buffer member and is long in the vertical direction.
Reference numeral 300 in FIGS. 1 and 2 denotes a handle provided on the front and rear surface plates 62 and 63 at the door end side (remaining portion) of the sliding door 6. Reference numeral 301 denotes a locking device for the sliding door 6.

The front concave portion 700 and the rear concave portion 701 are formed by the convex member 7.
The convex member 7 is erected on the upper part of the sliding door, is long in the opening / closing direction, and is a cross-section downwardly-coordinated set to be thinner than the entire thickness of the sliding door 6 formed between the front plate 62 and the rear plate 63 of the sliding door 6. The protrusion 72 has a letter shape, and includes a front support protrusion 721 and a rear support protrusion 722 that protrude forward and backward from the lower end of the protrusion 72, respectively. The protrusion 72 is an opening / closing direction (width direction) of the sliding door 6. And the length of the same dimension.

The upper surface of the front support protrusion 721 of the convex member 7 is covered with a bent portion that is bent at the upper portion of the front plate 62, and the upper portion of the rear support protrusion 722 is covered with a bent portion that is bent at the upper portion of the rear plate 63. It is done. By doing in this way, in the upper part of the sliding door 6, only the bent part of the surface plate can be seen, so that the end face of the front and rear support projecting pieces is not seen and the appearance is good.
Thus, since the convex member 7 is thinner than the entire thickness of the sliding door 6, step-shaped concave portions (the front concave portion 700 and the rear concave portion 701) are formed between the surface plate of the sliding door 6 and the convex member 7. .
The concave portion is a portion in which the lower portion of the maintenance panel 9 is accommodated.
The convex member 7 can prevent the structure of the sliding door device from being seen through a slight gap created below the lower end of the maintenance panel, and light on the facing side across the sliding door can be prevented from leaking to the other side.

The upper cover 8 is used in the case of the outset type sliding door device installed on the wall surface in the present embodiment, and in the case of the outset type sliding door device, the maintenance panel is only the front portion, Since the rear recess 701 is unnecessary, the step between the rear plate 63 and the convex member 7, that is, the rear recess 701 is filled.
Accordingly, the upper cover 8 has a rear recess 701 that has a surface 8a that is flush with the rear plate 63 of the sliding door 6 and is set to a length that is substantially the same as the opening / closing direction (width direction) of the sliding door 6. ing.
Even without the upper cover 8, the rear recess 701 may be filled by pulling up the upper end of the rear plate 63 to the upper part.

Rotating rollers 10 and 10 that rotate about a vertical axis as a rotation axis are attached to the door end side end and the door bottom side end of the upper surface of the sliding door 6 configured as described above.
The rotation roller 10 has a rotation axis set at the center in the front-rear (out / in) direction of the sliding door 6, and the roller diameter does not protrude from the front plate 62 and the rear plate 63 of the sliding door 6, but from the thickness dimension of the sliding door 6. The diameter is slightly smaller and larger than the thickness of the convex member 7.
Then, the suspended hexagon bolts 61 and 61 are screwed into screw holes provided in the sliding door upper frame 64 of the sliding door 6.

  The sliding door 6 is lowered from the upper part of the guide device 4 so that the guide roller 41 of the guide device 4 fixed to the floor surface is inserted into the fitting groove 60 at the lower end of the sliding door 6, and from the front side of the entrance / exit The screw shafts of the hanging hexagon bolts 61 and 61 are inserted through the suspension bolt insertion holes of the suspension support portion 53, and the bolt head is held by the suspension support portion 53. Are moved by a spanner to position the sliding door 6 at a predetermined height, and then bolt holders 65 and 65 are connected to the suspension support portion 53 from the front side, and the suspension bracket 51 is attached to the rail member 50. It is hung through.

Further, a spring type self-closing device (not shown) is arranged between the door end side end of the hanging bracket 51 and the door end side end of the rail holding member 5 in a state where the sliding door 6 is suspended. And a brake device (not shown) is provided between the rail holding member 5 and the hanging bracket 51 to obtain a desired self-closing speed of the sliding door 6. In addition, since the spring-type self-closing device and the brake device of the embodiment are well-known (commercially available), description thereof is omitted. In addition, a known (commercially available) sliding door retracting device may be used instead of the spring-type self-closing device and the brake device.

The maintenance panel 9 is sized to cover the rail reinforcing member 2, that is, formed in a length from the entrance / exit side to the retracting side, and with the front panel 62 of the sliding door 6 attached to the maintenance panel 9. A front surface plate 91 that is flush with each other, an upper plate 92 that extends rearward from the upper end of the front surface plate 91, a reinforcing piece 92a that hangs down from the extended end of the upper plate 92, and left and right ends of the front surface plate 91, respectively. It consists of side plates 93 and 93 extending rearward and a maintenance panel lower projection 94 accommodated in a front recess 700 formed in the upper part of the sliding door.
A plate-like guide plate 95 is attached from the lower end on the inner surface (rear surface) side of the front surface plate 91 to the upper portion.

The maintenance panel 9 thus formed is reinforced to the maintenance panel hanging material 11a which can be adjusted up and down and vertically on the upper surface of the central portion of the rail holding member 5 in a state where the sliding door 6 is suspended. After hooking the piece 92 a, the rail holding member 5 is fixed to the maintenance panel mounting members 11, 11 fixed to the left and right ends of the rail holding member 5 with the decorative screws 12, 12.
When the front and rear of the maintenance panel hanging member 11a are adjusted up and down, the verticality and the front and rear positions near the center of the maintenance panel 9 can be adjusted.

Since the sliding panel device 100 in which the respective members are attached and assembled as described above can accommodate the maintenance panel lower protrusion 94 in the front concave portion 700 of the sliding door 6, the front surface plate 91 of the maintenance panel 9 and the front of the sliding door 6 The face plate 62 can be formed substantially flush.
However, in order to make the front surface plate 91 of the maintenance panel 9 and the front plate 62 of the sliding door 6 substantially flush with each other, a space between the vertical surface of the convex member 7 and the vertical surface of the maintenance panel lower protrusion 94 is limited. Cannot be set large.
In addition, since the maintenance panel 9 is long in the opening / closing direction, it is not possible to suppress the occurrence of some distortion in the production of the maintenance panel 9.

Therefore, if the gap between the convex member 7 and the maintenance panel lower protrusion 94 is small, the convex member 7 (upper cover 8) and the maintenance panel lower protrusion may directly interfere with each other due to the distortion of the maintenance panel 9.
As described above, when the convex member 7 (upper cover 8) and the maintenance panel lower protrusion directly interfere with each other, there is a problem that a rubbing sound is generated and that the sliding door is opened and closed due to interference resistance.
And it is a subject of this invention to eliminate such a problem.

In the embodiment, the side surface of the rotating roller 10 on the upper surface of the sliding door 6 is close to the guide plate 95 on the inner surface of the maintenance panel 9, and the rotating roller 10 has a vertical axis as the rotation axis. It can rotate in the opening and closing direction.

The gap between the side surface of the adjacent rotating roller 10 and the guide plate 95 is set smaller than the gap between the convex member 7 and the maintenance panel lower protrusion 94.
Therefore, before the convex member 7 (upper cover 8) and the maintenance panel lower protrusion directly interfere with each other, the side surface of the rotating roller 10 and the guide plate 95 come into contact with each other.
Since the rotating roller 10 can rotate in the opening / closing direction of the sliding door 6, even if the side surface of the rotating roller 10 and the guide plate 95 are in contact with each other, there is no generation of rubbing noise or contact resistance.
The guide plate 95 serves to reinforce the maintenance panel in addition to adjusting the gap between the rotating roller 10 and the guide plate 95.

In this way, when the sliding door 6 passes through a portion where the gap between the convex member 7 and the maintenance panel lower projection 94 is reduced due to distortion of the maintenance panel 9 or displacement of the opening and closing track of the sliding door 6, Since the rotating roller 10 passes while pushing the maintenance channel 9 forward, the convex member 7 (upper cover 8) and the maintenance panel lower projection do not directly interfere with each other.
The rotating roller 10 may have a small diameter attached to the maintenance panel 9.

As shown in FIG. 8, you may provide a synthetic resin sliding body in two places of the both ends of the opening / closing direction of the vertical surface by the side of the maintenance panel of the convex member 7 (upper cover 8) of the sliding door 6. As shown in FIG.
The sliding member 10a prevents the convex member 7 (upper cover 8) and the maintenance panel lower protrusion from directly interfering with each other. Further, since the sliding body 10a is partially installed, even if the sliding body 10a and the maintenance panel interfere with each other, the contact area is small, so there is no great resistance, and there is no hindrance to opening and closing the sliding door 6.
Moreover, you may install the sliding body 10a in the maintenance panel side, as shown in FIG. When installing on the maintenance panel side, it is better to install a plurality of them in accordance with the opening and closing track of the sliding door 6.
Although the sliding body 10a is a synthetic resin, the thing of the material which was hard and excellent in sliding property is suitable.

In this way, when the sliding door 6 passes through a portion where the gap between the convex member 7 and the maintenance panel lower projection 94 is reduced due to distortion of the maintenance panel 9 or displacement of the opening and closing track of the sliding door 6, Since the sliding body 10a passes through the maintenance panel lower projection 94 of the maintenance panel 9 while pushing it forward, the convex member 7 (upper cover 8) and the maintenance panel lower projection do not directly interfere with each other.

The sliding door device in the present embodiment is an outset type installed on the surface of the wall surface, but the inset type in which the door pocket portion is installed in the wall and the open sliding door is accommodated within the thickness of the wall body. The present invention can also be used for sliding door devices.
