Description

  The present invention relates to an upward-sliding sliding door device, and more particularly to an upward-sliding sliding door device capable of suppressing shaking of the sliding door during opening and closing.

  As shown in FIGS. 6 to 8, the conventional upper sliding door device 80 can run on the rail 2 via a door wheel 82 in which a bracket 81 disposed on the upper part of the sliding door D is rotatably disposed on the bracket 81. The sliding door D is opened and closed by attaching to the door.

  The rail 2 is fixed to an upper frame 85 of an upper frame 85, a lower frame 86, and left and right side frames 87, 87 attached to an open portion (entrance / exit portion) of the wall surface, and a cross section C with the open side facing downward. A door wheel 82 is placed on a traveling surface 2A that has a character-like structure and projects inwardly from both lower ends of the rail 2.

In general, the rail 2 is fixed to the upper frame 85 by a fixing means such as a bolt after the door wheel 82 is placed.

JP 2001-288951 A JP 2005-351081 A

By the way, this upper suspension type sliding door apparatus 80 has a gap of a distance S between the upper part (vertex part) of the door wheel 82 and the inner top surface 2 </ b> B of the rail 2.
When the sliding door D is opened / closed, the sliding door D is normally operated with the handle of the sliding door D, but the force applied by the user to the handle is not necessarily parallel to the opening / closing direction of the sliding door D (horizontal direction), and slightly up and down. It will tilt.
Therefore, as shown in FIG. 8, when the sliding door D is opened / closed, one of the door tip side door door or the door bottom side door wheel 82 running on the rail 2 is driven by the rail by the force in the diagonal direction applied to the sliding door D. Although contacting the surface 2A, the other is lifted from the traveling surface 2A of the rail 2.
As a result, the sliding door D is opened and closed in an inclined state, and there is a problem that abnormal noise occurs or the door wheel 82 and the rail 2 are damaged.

  In addition, in the case of the upper suspension type sliding door, there is a problem that a gap is generated between the lower surface of the rail 2 and the upper surface of the sliding door D, and light leakage from the room partitioned by the sliding door D to the outside or the outside to the room occurs.

  In addition, in the case of a suspended sliding door, the vertical line passing through the center of gravity of the bracket on which the pair of opposed door wheels 82 are disposed is aligned with the vertical line passing through the center of gravity of the sliding door D. When the surface 2A is slightly inclined as shown in FIG. 7 (b), the pair of facing door wheels 82 do not abut against the traveling surface 2A of the rail 2 evenly, and the sliding door D is brought into contact with one traveling surface 2A. The sliding door D may be fully loaded on the traveling surface 2A that comes into contact with the door wheel 82, and the rail 81 may be damaged or the bracket 2 and the rail 2 or the side surface of the door wheel 82 and the rail 2 may be moved when the rail 2 is opened or closed. There was also a problem that abnormal noise might be generated by contact.

  In view of the problems of the above conventional hanging type sliding door device, the present invention, in the hanging type sliding door device, when the sliding door is opened and closed, even if an oblique force is applied to the sliding door, the lifting of the door wheel is suppressed, It is a first object of the present invention to provide an upholstered sliding door device that can move a sliding door smoothly.

  A second object is to suppress the light leakage by reducing the gap between the lower surface of the rail and the upper surface of the sliding door as much as possible.

  Furthermore, even when the rail is tilted by displacing the vertical line passing through the center of gravity of the pair of opposed door wheels that normally coincide with the vertical line passing through the center of gravity of the sliding door, the pair of driving door wheels facing each other even when the rail is tilted It is a third object to make it possible to abut evenly.

  In order to achieve the first object described above, the upwardly sliding sliding door device of the present invention is an upwardly suspended sliding door device that opens and closes the sliding door by attaching a suspension unit disposed on the upper part of the sliding door so as to be able to run freely. A traveling door wheel that travels on the traveling surface of the rail, a guide door wheel that is capable of contacting the inner top surface of the rail, and a height direction of the traveling door wheel and the guide door wheel And a level adjusting mechanism for adjusting the distance between the two.

  In this case, the level adjustment mechanism is configured such that the first moving block in which the guide door is disposed along the inclined surface whose height gradually changes in the opening / closing direction of the sliding door is set by the first screw member. By moving relative to the main body, it can be configured to be displaced in the vertical direction.

  In order to achieve the second object, the main body of the suspension unit is slid onto the inclined surface on an attachment member in which an inclined surface whose height gradually changes in the opening / closing direction of the sliding door is formed in the interior fixed to the sliding door. The upper and lower parts are mounted via a second moving block and a second screw member that are in contact with each other, and are displaced in the vertical direction by moving the second moving block relative to the mounting member by the second screw member. A direction adjustment mechanism can be provided.

  Further, in order to achieve the third object, the main body of the suspension unit is attached to the interior of the sliding door formed with an inclined surface that is parallel to the vertical direction and has an angle with respect to the top surface of the sliding door. By attaching to the member via a third moving block and a third screw member that are in sliding contact with the inclined surface, and moving the third moving block relatively by the third screw member, A horizontal adjustment mechanism for displacing in a parallel direction can be provided.

  According to the upper suspension type sliding door device of the present invention, the suspension unit attached to the upper part of the sliding door is movably attached to the rail so that the sliding door is opened and closed, and the traveling surface of the rail is attached to the body of the suspension unit. A traveling door pulley for traveling, a guide door wheel capable of coming into contact with the inner top surface of the rail, and a level adjusting mechanism for adjusting a distance in the height direction between the traveling door wheel and the guide door wheel are provided. Thus, even when the sliding door is opened and closed, the force applied to the sliding door is tilted without being parallel to the opening and closing direction of the sliding door. However, it can contact the inner top surface of the rail immediately, minimize the tilt of the sliding door, suppress the lifting of the door cart, move the sliding door smoothly, and has less rattling. Can effectively prevent damage to rails Kill.

  In addition, the level adjustment mechanism may be configured such that the first moving block in which the guide door wheel is disposed is disposed along the inclined surface whose height gradually changes in the opening / closing direction of the sliding door by using the first screw member, and the main body of the suspension unit Since the block in which the guide door is arranged is displaced in the vertical direction along the inclined surface, the guide door and the rail are arranged. Fine adjustment of the gap with the inner top surface can be easily performed.

  In addition, a second moving block that is in sliding contact with the inclined surface and a second moving block are formed on an attachment member in which the main body of the suspension unit is fixed to the sliding door, and an inclined surface whose height gradually changes in the opening / closing direction of the sliding door is formed. By attaching a vertical adjustment mechanism that displaces in the vertical direction by moving the second moving block relative to the mounting member by the second screw member, the sliding door is attached via the screw member. After hanging on the rail, the gap created between the upper surface of the sliding door and the lower surface of the rail can be made as small as possible, minimizing light leakage from the room partitioned by the sliding door to the outside or from the outside to the room. Can be suppressed.

  In addition, the main body of the hanging tool unit is slidably contacted with the inclined surface to an attachment member in which an inclined surface that is parallel to the vertical direction and has an angle with respect to the mouth surface of the sliding door is formed in the interior fixed to the sliding door. A horizontal adjustment mechanism that is attached via a third moving block and a third screw member, and is displaced in a direction parallel to the sliding surface of the sliding door by moving the third moving block relatively by the third screw member. The sliding door can be displaced in a horizontal direction parallel to the sliding door's top surface with respect to the traveling door wheel mounted on the rail, so that the traveling surface of the rail attached to the upper frame Even if it is not exactly horizontal, the position of the vertical line that passes through the gravity center of the sliding door is displaced relative to the vertical line that passes through the gravity center of the pair of opposite traveling carriages. Traveling door It can be can be evenly contact, suppressing the occurrence of rail damage or abnormal sound.

  DESCRIPTION OF EMBODIMENTS Hereinafter, an embodiment of an upwardly sliding sliding door device of the present invention will be described based on the drawings.

FIG. 1 to FIG. 5 show an embodiment of the upward sliding sliding door device of the present invention.
The upper suspension type sliding door device 1 is configured such that a suspension unit 10 disposed on an upper part of a sliding door D is movably attached to a rail 2 so as to open and close the sliding door D, and a traveling surface of the rail 2 is attached to a body 11 of the suspension unit. Level adjustment that adjusts the distance in the height direction between the traveling door pulley 3 that travels 2A, the guide door wheel 4 that can contact the inner top surface 2B of the rail 2, and the traveling door wheel 3 and the guide door wheel 4 The mechanism 5 is provided.

  Like the conventional example, the rail 2 has a C-shaped structure with the open side facing downward, and the traveling door pulley 3 is placed on the traveling surface 2A projecting inward from the lower ends of the rail 2, It is comprised from the upper part of the traveling door pulley 3 mounted in the traveling surface 2A, and the inner top surface 2B which has the clearance gap of the distance S. FIG.

The main body 11 of the lifting device unit is provided with a traveling door wheel 3 that travels on the traveling surface 2A of the rail 2 at the upper portion thereof, and is configured to be able to contact the inner top surface 2B of the rail 2. The distance between the top of the guide door 4 and the inner top surface 2B of the rail 2 is adjusted by adjusting the height of the door 4 with the level adjustment mechanism 5 in the height direction between the traveling door 3 and the guide door 4. It is arranged so that it can be adjusted.
The number of travel doors 3 and guide doors 4 disposed on the main body 11 of the suspension unit is not particularly limited, but in this embodiment, the travel door 3 is connected to the main body 11 of the suspension unit. One guide door 4 is disposed between the traveling doors 3 at each of the upper ends.

  The level adjustment mechanism 5 adjusts the distance between the traveling door pulley 3 and the guide door wheel 4 in the height direction, thereby adjusting the distance between the top of the guide door wheel 4 and the inner top surface 2B of the rail 2. In the present embodiment, the guide door 4 is disposed along the inclined surface 51A whose height gradually changes in the opening / closing direction of the sliding door D. The first moving block 50 is configured to be displaced in the vertical direction by moving the first moving block 50 relative to the main body 11 of the hanger unit by the first screw member S1.

Specifically, the inclined block 51 formed with the screw hole 51B and the inclined surface 51A into which the screw member S1 rotatably arranged parallel to the opening and closing direction of the sliding door D is formed, and the sliding contact with the inclined surface 51A. The first moving block 50 is provided with a guide door pulley 4 having a contact surface 50A.
The 1st moving block 50 and the inclination block 51 are arrange | positioned in the notch part (upper center part) between the traveling door pulleys 3 and 3 of the main body 11 of a hanging tool unit, and the screw hole 51B of the inclination block 51 is the The first moving block 50 screwed into the screw member S1 and provided with the guide door 4 is located between the side surface of the cut-out central portion of the upper part of the main body 11 of the suspension unit, as shown in FIG. ), The dovetail groove and the tenon allow the displacement in the vertical direction to prevent falling off and are arranged so that the sliding contact surface 50A is in contact with the inclined surface 51A of the inclined block 51.
The screw member S1 can be rotated by a tool such as a driver, and the first moving block 50 can be relatively moved so that the head does not move even if the screw member S1 is rotated. As shown in FIG. 3, the screw member S1 is externally accommodated in a screw member storage space 12A cut out in a U-shape so as to open a half surface, and allows a rotating operation by a tool such as a screwdriver. Although the cross hole portion (cross hole in the present embodiment) of the head can be seen, the movement of the head in the axial direction is restricted by the protrusion 13A of the main body 11 of the lifting device unit.

In addition, as shown in FIG. 2F, when the first moving block 50 is positioned between the head of the screw member S1 and the inclined block 51, the screw portion of the screw member S1 is provided on the lower surface thereof. The notch 50B is formed so that is inserted.
Then, by rotating the screw member S1, the inclined block 51 is displaced in parallel with the opening / closing direction of the sliding door D, and by being displaced to the right in the figure, the sliding contact surface 50A slidably contacting the inclined surface 51A is moved upward. In response to this force, the first moving block 50 is displaced upward.
As a result, the distance in the height direction between the traveling door pulley 3 and the guide door wheel 4 is adjusted, and the guiding door wheel 4 is compared with the traveling door wheel 3 placed on the traveling surface 2 </ b> A of the rail 2. Moves vertically, and the distance between the guide door 4 and the inner top surface 2B of the rail 2 is adjusted.

The guide door 4 may be displaced upward until the distance between the traveling door 3 and the guide door 4 in the height direction contacts the inner top surface 2B of the rail 2 by adjustment. It is preferable to adjust so that a slight gap is generated so that the operation of the sliding door D is not hindered by the expansion.
Thereby, even if the force applied to the sliding door D tilts without being parallel to the opening / closing direction of the sliding door D, the guide door wheel 4 immediately comes into contact with the inner top surface 2B of the rail 2, and the sliding door D It is possible to minimize the inclination and effectively prevent the traveling door pulley 3 and the rail 2 from being damaged.

  In addition, the second moving block that is in sliding contact with the inclined surface 60 is attached to the mounting member 20 in which the inclined surface 60 whose height gradually changes in the opening / closing direction of the sliding door D is formed inside the suspension unit main body 11 fixed to the sliding door D. 61 and the second screw member S2 are attached, and the second moving block 61 is moved up and down by moving the second moving block 61 relative to the attachment member 20 by the second screw member S2. A mechanism 6 can be provided.

  Specifically, as shown in FIG. 3A, attachment portions 14, which are spaces for attaching the attachment members 20, are attached to the lower portion of the main body 11 of the suspension unit from both lower ends of the main body 11 of the suspension unit. The extended flanges 11A and 11A and the lower part of the main body 11 of the suspension unit are defined and formed, and the attachment member 20 is attached via the second moving block 61 and the second screw member S2.

The attachment member 20 has an inclined space 21 that forms an inclined surface 60 therein, and forms a through hole 22 parallel to the opening / closing direction of the sliding door D that penetrates the inclined space 21.
The through hole 22 functions as a space through which the screw member S2 is inserted and moved.
Then, the second moving block 61 is provided in the inclined space 21, and the second moving block 61 is relatively moved along the inclined surface 60.

The second moving block 61 is screwed into the screw hole 61A in parallel with the opening / closing direction of the sliding door D, the screw member S2 suspended from the flanges 11A and 11A is screwed into the screw hole 61A, and the screw member S2 is rotated. By doing so, the sliding door D is displaced in parallel with the opening / closing direction of the sliding door D while being in sliding contact with the inclined surface 60, and the sliding door D is displaced in the vertical direction via the attachment member 20.
In the present embodiment, the inclined surface 60 is formed so as to face each other in parallel as shown in the figure. However, since the mounting member 20 receives the weight of the sliding door D, the sliding surface D is simply provided on the left side of the drawing. Can be displaced vertically.

The inclined space 21 is formed so as to penetrate in the width direction (horizontal direction) of the mounting member 20, and the second moving block 61 is positioned in the inclined space 21 with an equal gap vertically between the through holes 22. The screw member S2 inserted through is screwed into the screw hole 61A.
When the mounting member 20 is positioned on the mounting portion 14, the screw member S2 is positioned in the back of the screw member storage space 12B formed in the flanges 11A and 11A.
Similarly to the screw member storage space 12A, the screw member storage space 12B is configured to be cut out in a U shape so as to open a half surface, and similarly to the screw member S1, the protrusion 13B of the main body 11 of the suspension unit. Thus, although the rotation work by a tool such as a driver is permitted, the movement of the screw member S2 in the axial direction is restricted.
As described above, even if the screw member storage space 12B is cut out in the horizontal direction, the second moving block 61 applies a force only from the inclined surface 60 in the vertical direction. There is no problem.

  In addition, the attachment member 20 in which the slanting surfaces 70 and 70 facing the parallel to the vertical direction with an angle with respect to the front surface of the sliding door D are formed in the interior of the suspension unit main body 11 fixed to the sliding door D. The sliding door D is attached by moving through the third moving block 71 and the third screw member S3 that are in sliding contact with the inclined surfaces 70 and 70, and relatively moving the third moving block 71 by the third screw member S3. It is possible to provide a horizontal direction adjusting mechanism 7 that is displaced in a direction parallel to the wood end surface.

  Specifically, like the mounting member 20 provided with the vertical adjustment mechanism 6, the mounting member 20 includes flanges 11 </ b> A and 11 </ b> A extending from both lower ends of the main body 11 of the hanging unit and the main body 11 of the hanging unit. The mounting member 20 is mounted on the mounting member 14 via the third moving block 71 and the third screw member S3.

The mounting member 20 has an inclined space 23 which forms inclined surfaces 70 and 70 which are opposed in parallel to each other in the vertical direction and have an angle with respect to the front surface of the sliding door D. A through hole 24 parallel to the opening / closing direction is formed.
The through hole 24 functions as a space through which the screw member S3 is inserted and moved.
A third moving block 71 is provided in the inclined space 23, and the third moving block 71 is relatively moved along the inclined surfaces 70 and 70.

The third moving block 71 is screwed into the screw hole 71A in parallel with the opening / closing direction of the sliding door D, the screw member S3 suspended from the flanges 11A and 11A is screwed into the screw hole 71A, and the screw member S3 is rotated. By doing so, the sliding door D is displaced in a horizontal direction parallel to the front surface of the sliding door D while being in sliding contact with the inclined surfaces 70, 70, and the sliding door D is displaced in a horizontal direction parallel to the front surface of the sliding door via the attachment member 20.
Unlike the inclined surface 60, the inclined surface formed on the mounting member 20 of the horizontal direction adjusting mechanism 7 is not affected by the weight of the sliding door D, and must be provided in parallel with each other.

The inclined space 23 is formed in a bottomed shape so as to open the lower surface side of the mounting member 20, and has a gap that is equal to the opposing surfaces other than the inclined surfaces 70, 70 when the third moving block 71 is viewed from the bottom. When the screw member S3 inserted through the through hole 24 is screwed and the mounting member 20 is positioned on the mounting portion 14, the screw member S3 is positioned in the back of the screw member storage space 12C formed in the flanges 11A and 11A. Let
Similarly to the vertical adjustment mechanism 6, the screw member storage space 12C is formed by notching a U-shape so as to open a half surface, and the protrusions of the main body 11 of the hanger unit similar to the screw members S1 and S2. The part 13C is allowed to rotate with a tool such as a driver, but restricts the axial movement of the screw member S3.
Thus, when the screw member storage space 12C is cut out in the horizontal direction, unlike the second moving block 61, the third moving block 71 is applied with a horizontal force from the inclined surfaces 70, 70. This will hinder one displacement of the mounting member 20 in the horizontal direction.
Therefore, as shown in FIG. 3C, a lid member 74 that closes the vicinity of the head of the screw member S <b> 3 is provided and receives a horizontal force applied to the screw member S <b> 3 via the third moving block 71. Thus, the horizontal displacement of the third moving block 71 is prevented from being hindered.

  Only one of the vertical direction adjustment mechanism 6 and the horizontal direction adjustment mechanism 7 can be provided, but as shown in FIG. 5, by providing both, the vertical direction of the sliding door D and Horizontal adjustment parallel to the end face can be performed.

  Next, an adjustment method using the level adjustment mechanism 5, the vertical direction adjustment mechanism 6, and the horizontal direction adjustment mechanism 7 of the upper suspended sliding door device 1 will be described.

  The level adjustment mechanism 5 may be performed either before or after connecting the suspension unit 10 and the sliding door D as long as the suspension unit 10 is attached to the rail 2. An example in which adjustment is performed after connection is shown.

  First, in the state where the hanging tool unit 10 is attached to the rail 2, there is a gap of a distance S between the guide door 4 and the inner top surface 2 </ b> B of the rail 2 as shown in FIG. 1. In this embodiment, the distance in the height direction (vertical direction) between the guide door 4 and the traveling door 3 having the same outer diameter is 0 in this state, and the distance in the height direction is S. The guide door 4 and the inner top surface 2B of the rail 2 come into contact with each other.

  Then, as shown in FIG. 4, the screw member S1 is rotated with a tool such as a screwdriver, and the inclined surface 51A of the inclined block 51 is moved to the right side in the figure, thereby contacting the inclined surface 51A. An upward force is applied to the sliding contact surface 50A of one moving block 50, and the first moving block 50 moves upward.

  As a result, the distance between the traveling door pulley 3 and the guide door wheel 4 is adjusted, the gap between the guide door wheel 4 and the inner top surface 2B of the rail 2 is reduced (or abuts), and the sliding door D is opened and closed. Even if the force applied to the sliding door D tilts without being parallel to the opening / closing direction of the sliding door D, the guide door wheel 4 immediately contacts (or contacts) the inner top surface 2B of the rail 2. Therefore, the sliding door D can be moved smoothly because the tilt of the sliding door D is minimized, the floating of the traveling door 3 is suppressed, and the sliding door can be moved smoothly. And the rail 2 can be effectively prevented from being damaged.

  Adjustment by the vertical direction adjustment mechanism 6 and the horizontal direction adjustment mechanism 7 passes through the adjustment of the gap between the lower surface of the rail 2 and the upper surface of the sliding door D and the center of gravity of the pair of traveling door pulleys 3 (the center of gravity of the suspension unit 10). Since it is performed in order to displace the vertical line and the vertical line passing through the center of gravity of the sliding door D, it is performed after the suspension unit 10 and the sliding door D are connected.

First, as shown in FIGS. 5A to 5B, the vertical adjustment mechanism 6 rotates the screw member S <b> 2 with a tool such as a screwdriver to bring the second moving block 61 to the inclined surface 60. The second moving block 61 is moved downward relative to the mounting member 20.
As a result, in the main body 11 of the suspension unit, the attachment member 20 moves upward relative to the second moving block 61 screwed with the screw member S2 whose vertical position is fixed, and the sliding door D The gap between the lower surface of the rail 2 and the upper surface of the sliding door D can be made as small as possible, and light leakage from the room partitioned by the sliding door D to the outside or the outside to the room is minimized. To the limit.

  Further, as shown in FIGS. 5C to 5E, the horizontal adjustment mechanism 7 rotates the screw member S3 with a tool such as a screwdriver so that the third moving block 71 is moved to the inclined surface 70, The third moving block 71 is moved relative to the mounting member 20 in the horizontal direction parallel to the end face.

In this embodiment, as shown in FIG. 5 (d), the sliding door D is adjusted so as to move to the right in a side view, and the sliding door D has a vertical line G <b> 1 passing through the center of gravity of the hanging unit 10. The vertical line G2 passing through the center of gravity is shifted by a distance L.
This corresponds to the traveling surface 2A of the rail 2 that is slightly inclined to the left as viewed from the side, and the pair of traveling door pulleys 3 that are opposed to the traveling surface 2A of the rail 2 can be evenly contacted. Rail breakage and abnormal noise can be suppressed.

  As mentioned above, although the upper suspension type sliding door apparatus of the present invention has been described based on the embodiments thereof, the present invention is not limited to the configurations described in the above embodiments, and the configurations thereof are appropriately set within the scope not departing from the gist thereof. It can be changed.

  Even if the force at the time of opening and closing operation is applied in an oblique direction, the upper suspension type sliding door device of the present invention does not move in a state where one of the door pulleys on the door end side or the door bottom side is lifted and the sliding door is inclined. Since it has the characteristic, it can be used suitably for the use of the upper suspension type sliding door with a clearance gap between the inner top surface of the rail and the door wheel.
