Description

  The present invention opens and closes the opening by moving the adjacent inner door in conjunction with the movement of the outer door when the outer door is moved in front among the plurality of sliding door type doors arranged in parallel. The present invention relates to an interlocking sliding door device.

  Conventionally, in this type of interlocking type sliding door device, as shown in FIG. 17, for example, the inner door a and the outer door b of the sliding door arranged in parallel to the depth direction of the opening s are fixed to the upper frame f. The doors 2a and 2b are engaged with the engaging projections 1a and 1b of the upper rail 1 and suspended, while the sliding roller 3 is rotatably supported by the support shaft 4a at the inner door a at the depth side in the depth direction. A pivoted L-plate-shaped support plate 4 is attached, and the peripheral surface of the sliding roller 3 is brought into contact with the outer mounting plate 5 protruding from the upper part of the outer door b and the bent piece 6 of the upper frame f. When the interlocking mechanism is formed and the outer door b is moved at the time of opening and closing, the inner door a also moves in the same direction with the outer door b while the sliding roller 3 contacting the outer door b rotates. There is something like that.

  In the conventional interlocking type sliding door device, as shown in FIG. 18 (A), a guide 7a having a right-angled triangular cross section is fixed to the back surface of the outer mounting plate 5, and at the height position facing the one side guide 7a, on the opposite side. The bent piece 6 is partly bent into a right triangle shape in accordance with the guide 7a to form a guide 7b, and both guides 7a and 7b are formed in a convex shape with their inclined surfaces facing each other. A spring 8 is wound around the support shaft 4a to urge the sliding roller 3 upward in the figure, and the peripheral surface of the sliding roller 3 is pressed against the inclined surfaces of both guides 7a and 7b by the urging force. Thus, even if a dimensional error occurs to some extent in the distance between the guides 7a and 7b due to the displacement and rattling in the processing, assembly and installation of the upper frame f, the outer mounting plate 5 and the doors a and b, The configuration that does not require the error adjustment is temporarily used.

Further, in the conventional interlocking type sliding door device, as shown in FIG. 18B, the peripheral surface of the sliding roller 3 is provided on the back surface of the outer mounting plate 5 of the outer door b and the inner surface of the bent piece 6 of the upper frame f. A pair of resin guides 9 and 9 each having a long groove 9a recessed according to the shape can be mounted with the long grooves 9a facing each other, and the sliding roller 3 can be engaged with the long grooves 9a to slide in the length direction. Even if a biasing spring such as the spring 8 is not used separately and there is a slight dimensional error in the distance between the guides 9 and 9, there is no need to adjust the error. In the meantime,

  However, in the conventional interlocking sliding door device 1, the sliding roller 3 is moved between the upper frame f and the outer door b as shown in FIG. 17, for example, so that the inner door a moves in conjunction with the adjacent outer door b. Although a sliding contact is made, a part of the upper frame f is bent to form the bent piece 6 so that the peripheral surface of the sliding roller 3 actually touches both of them. Since it is the structure which attached and protruded the body outer mounting plate 5, it requires the bending process of a troublesome metal plate more, and the outer mounting plate 5 is separately needed as a component. Further, in order to eliminate the need for adjusting the distance between the guides 7a and 7b, as shown in FIG. 18, the upper frame f is partially bent to provide the guide 7b, or the guide 7a and the guides 9 and 9 are separately raised. Since it is configured to be attached to the bent piece 6 or the outer mounting plate 5 of the frame f, it is further necessary to bend the troublesome metal plate, and a separate guide component is required as a component, and as a result, There is a problem that it takes time to process and assemble the interlocking mechanism, and the number of parts increases to make the structure complicated, thereby increasing the cost.

  Moreover, in the conventional interlocking sliding door device, since the bending accuracy of the bent piece 6 and the mounting accuracy of the outer mounting plate 5 are poor, for example, as shown in FIG. 19, the guides 7a and 7b are slightly placed at the installation height positions. However, if there is a deviation, a gap is generated between the peripheral surface of the sliding roller 3 and the inclined surfaces of both guides 7a and 7b. Therefore, even if the outer door b is moved during opening and closing, the sliding roller 3 Causes a problem that the inner door a does not move smoothly in conjunction with the movement of the outer door b, and the opening / closing operability of the interlocking sliding door is poor.

  Therefore, the object of the present invention is to simplify the structure by reducing the number of parts and reduce the cost, while at the same time moving the inner door to the outer door smoothly and interlocked without causing the interlocking roller to idle. An object of the present invention is to provide an interlocking type sliding door device that improves the opening / closing operability of the sliding door.

  In order to achieve the above-described object, the invention described in claim 1 includes, for example, a plurality of sliding door type doors A and B arranged in parallel in the depth direction of the opening S, as shown in the following illustrated embodiment, A guide rail L that is fixed to one or both of the upper frame 12 and the lower frame 13 of the opening S and guides the doors A and B in the opening and closing directions X and Y, and the inner side of the door in the depth direction. A support means 30 attached to the door A includes an outer door B with a circumferential surface 25a in front of the depth direction and an interlocking roller 25 in contact with the guide rail L. When the outer door B is moved to the front, The interlocking sliding door device that opens and closes the opening S by moving the inner roller A in the same direction in conjunction with the outer door B while the interlocking roller 25 in contact with the door B rotates. The means 30 pivotally attaches the interlocking roller 25 to the shaft tip 35a. A roller shaft 35, a movable holder 40 that is attached to one of the upper part and the lower part of the inner door A so as to be rotatable in the depth direction of the opening S, and holds the roller shaft 35 so as to be linearly movable in the axial direction; It is interposed between the movable holder 40 and the roller shaft 35, and the roller shaft 35 is biased obliquely toward the intersection line P where the shaft tip 35a intersects the guide rail L and the inner plate surface 41 of the outer door B. And an urging spring 50 in which the interlocking roller 25 is loosely moved by the urging force of the oblique direction so that the peripheral surface 25a is always brought into direct contact with both the outer door B and the guide rail L and pressed. And

  According to the first aspect of the present invention, the roller shaft of the interlocking roller is held by the movable holder of the support means so as to be able to rotate in the depth direction of the opening and to be linearly movable in the axial direction, and to be The tip is always biased diagonally toward the line where the inner plate surface of the outer door intersects with the guide rail, and the peripheral roller always moves the inner surface of the guide rail and the outer door by moving the interlocking roller with the diagonal biasing force. Because it is configured to be pressed against both sides of the surface, for example, there is a gap in the interval between the outer doors and the height of the inner door relative to the inner door, and the doors and guide rails are processed, assembled, Even if there is a variation in installation or there is a deformation part, based on the urging force of the urging spring, the shaft tip of the roller shaft is directed to the intersection line between the guide rail and the inner plate surface of the outer door, Connect the interlocking roller to the guide rail where there is misalignment or deformation. Of follow to both to the idler, the peripheral surface can be always pressed against no gap in both the inner plate surface of the outer door and the guide rail. Therefore, when the outer door is moved during opening and closing, the interlocking roller always contacts and presses against both the guide rail and the inner plate surface of the outer door. The door and guide rail rotate with the friction force of the uniform contact surface to transmit the power to the inner door, and as a result, the inner door and the outer door move smoothly in conjunction with each other, Open / close operability of the interlocking sliding door can always be kept good.

  Moreover, according to the first aspect of the present invention, the roller shaft of the interlocking roller is urged by the urging spring, and the shaft tip is in a direction toward the intersection line where the inner rail of the outer door intersects the guide rail. For the first time by tilting and attaching the support means diagonally to the inner door, the peripheral surface of the interlocking roller is always directly applied to both the guide rail and the inner plate surface of the outer door without any additional guides. As a result, it is possible to reduce the time and number of parts required for processing, simplifying the structure, as much as unnecessary bending of metal plates and components are unnecessary for the guide. Cost reduction can also be achieved.

  Hereinafter, the best mode of the present invention will be described with reference to the drawings.

As shown in FIG. 6, the upper rail 14 includes a curtain plate frame 16 having a U-shaped cross section and a rail body 17 fixed to the inside of the curtain plate frame 16. The rail body 17 is formed by projecting two guide ribs 17b and 17c parallel to the lower surface of the base plate portion 17a at a predetermined interval corresponding to a predetermined interval between the inner door A and the outer door B. On the other hand, as shown in FIGS. 4 and 5, the lower rail 15 is formed by projecting two rows of guide ribs 15 a and 15 b similar to the upper rail 14 upward at a predetermined interval. Therefore, in the guide rail L, as shown in FIG. 6, the upper rail 14 has guide ribs 17 b and 17 c facing downward as both flange portions 16 a of the curtain plate frame 16, and the curtain frame 16 is attached to the upper frame 12. Stick. As shown in FIGS. 4 and 5, the lower rail 15 is formed by fixing the substrate portion 15c on the lower frame 13 with the guide ribs 15a and 15b facing upward (see also FIGS. 11 and 12).

  Each of the inner door A and the outer door B is a wooden sliding door having a rectangular panel shape. As shown in FIG. 1, engagement grooves 18 a and 18 b corresponding to the guide ribs 17 b and 17 c of the upper rail 14 are formed on the upper end surface 18. It is recessed. The lower end surface 19 is provided with mounting recesses near the door tip and the door bottom, and the mounting body 21 pivotally supporting the door wheel 20 having the engagement recesses 20a and 20b on the circumference is assembled to these mounting recesses ( (See FIGS. 11 and 12). The outer door B is provided with a vertically long handle 22 on the door end side.

  Therefore, in the illustrated sliding door structure, as shown in FIGS. 1 and 6, the guide rib 17 b of the upper rail 14 is engaged with the engagement groove 18 a of the inner door A, and the guide rib 15 a of the lower rail 15 is engaged with the door 20. The inner door A is assembled in the depth direction inside the door frame F by engaging with the recess 20a, then the guide rib 17c of the upper rail 14 is engaged with the engaging groove 18b of the outer door B, and the lower rail 15 The guide rib 15b is engaged with the engaging recess 20b of the door pulley 20 and the outer door B is assembled in front of the inner door A in the door frame F in the depth direction, and both doors A and B are opened and closed along the partition wall W. It is arranged so that it can reciprocate in the direction.

  In the sliding door structure described above, when the outer door B is moved in the opening and closing direction by placing the hand on the puller 22, the interlocking sliding door device of the present invention operates, and the inner door A is also interlocked with the movement of the outer door B. Thus, the opening S is opened and closed by moving in the same direction with a delay.

  Therefore, as shown in FIG. 1, the interlocking sliding door device of the present invention includes an interlocking roller 25 and support means 30 that supports the interlocking roller 25 so that the peripheral surface 25a is in pressure contact with both the outer door B and the guide rail L. It has a configuration with.

  As shown in FIG. 2, the interlocking roller 25 has a roller body that is formed of a hard rubber in a donut shape, and a cylindrical boss 26 made of resin is fitted into the center hole 25b to form a tire mold as a whole. The material of the roller body of the interlocking roller 25 is not limited to rubber, but may be a friction material that can transmit power by the frictional force of the contact surface, such as resin.

  The support means 30 includes a roller shaft 35 that pivotally supports the interlocking roller 25, a movable holder 40 that holds the roller shaft 35, a mounting substrate 45 that attaches the movable holder 40 to the inner door A, and a biasing spring that includes a coil compression spring. 50.

  The roller shaft 35 is made of metal, has a plurality of circumferential narrow grooves m, n, and r on the outer periphery, and has a shaft tip 35a formed in a one-step narrow diameter. The movable holder 40 is formed by bending a metal plate into a U shape and opening circular shaft holes 41, 42, 43 in each of the holding pieces 40 a, 40 b facing each other and a connecting piece 40 c between the holding pieces. The mounting board 45 is provided with a notch recess 45a at one end in the lengthwise direction of a vertically long metal flat plate in accordance with the engagement groove 18a of the inner door A, and a circumferential narrow groove v on the outer periphery on one side plate surface. A pivot 46 provided with a projection is provided.

  Therefore, the support means 30 engages the pivot 46 of the mounting substrate 45 with the shaft hole 43 of the connecting piece 40c of the movable holder 40, and fits the E ring 31 in the circumferential narrow groove v on the outer periphery of the protruding end. Is connected to the mounting substrate 45 in a rotatable manner. On the other hand, the shaft tip 35a of the roller shaft 35 is inserted into the central boss hole 26a of the interlocking roller 25, and the E ring 32 is fitted into the circumferential narrow groove m on the outer periphery of the protruding end of the shaft tip 35a. Is pivotally attached to the shaft tip 35a. Next, the shaft base end 35b of the roller shaft 35 is connected to the shaft hole 41 of the holding piece 40a of the movable holder 40, the center hole of the O-shaped spring retainer ring 33, the center hole of the biasing spring 50, and the shaft hole 42 of the holding piece 40b. The E-ring 34 is fitted into the circumferential narrow groove n between the holding pieces 40a and 40b, while the E-ring 36 is fitted into the circumferential narrow groove r on the outer periphery of the protruding end of the shaft base end 35b. To do. As a result, the roller shaft 35 is held by the movable holder 40 so as to be linearly movable, and as shown in FIG. 3, the biasing spring 50 wound around the roller shaft 35 between the holding piece 40b and the spring pressing ring 33. The E-ring 36 is pressed against the holding piece 40b of the movable holder 40 and held in a state of being prevented from coming off and assembled as a roller assembly R. The roller assembly R is assembled to the mounting substrate 45. On the other hand, the support means 30 is constituted by being pivotably connected around a pivot 46.

  As shown in FIGS. 1 and 6, the support means 30 having such a structure aligns the notch recess 45 a of the mounting substrate 45 with the engagement groove 18 a in the upper part of the inner door A, and attaches the mounting substrate 45 to the door end side. The roller assembly R is attached to the inner door A in a suspended state so as to be rotatable in the depth direction of the opening S perpendicular to the opening / closing direction with the pivot 46 as a fulcrum. Then, after the interlocking roller 25 is pushed toward the movable holder 40 against the urging spring 50, the roller assembly R is rotated toward the outer door B to be inclined with respect to the inner door A, and the shaft of the roller shaft 35 is After the front end 35a is directed to the intersection line P where the inner plate surface 41 of the outer door B intersects the upper rail 14, the pushing of the interlocking roller 25 is released, and the spring urging force of the urging spring 50 acts diagonally. As shown in FIG. 3, the peripheral surface 25a of the interlocking roller 25 is in direct contact with both the inner plate surface 41 of the outer door B and the upper rail 14, and is in pressure contact therewith.

  Now, in the interlocking sliding door device having the above-described configuration, as shown in FIGS. 4 and 5, when opening the fully closed opening S, the user pulls the handle 22 from the outside in front of the drawing and opens the opening direction X When the outer door B is pulled and moved, the interlocking roller 25 in pressure contact with the outer door B transmits power to the inner door A while rotating by the frictional force of the contact surface as the outer door B moves. Moves in the same X direction with delay. That is, as shown in FIG. 7, the moving distance of the interlocking roller 25 is d / 2 with respect to the moving distance d of the outer door B, and the interlocking roller 25 moves with a corresponding delay. Therefore, the inner door A moves by a distance of d / 2 of the outer door with respect to the moving distance of the outer door B, so that the doors A and B are finally partitioned simultaneously as shown in FIG. It overlaps in front of the wall W, and the opening S is fully opened.

  In the above sliding door structure, as shown in FIG. 1, the upper rail 14 is horizontally fixed to the upper frame 12, while the outer door B is in a built-up state suspended vertically, In the roller assembly R, the roller shaft 35 is inclined at an inclination angle of 45 degrees with respect to the upright inner door A, and the shaft tip 35a is directed toward the intersecting line P of the upper rail 14 and the inner plate surface 41 of the outer door B. It is desirable to attach it. As a result, the support means 30 is configured so that the peripheral surface 25a of the interlocking roller 25 is in pressure contact with the inner plate surface 41 of the outer door B and the upper rail 14 at the same circumferential position. Power can be transmitted to the inner door A by rotating with the friction force of the equal contact surface between the door B and the upper rail 14, so that the inner door A can be smoothly interlocked with the outer door B without rattling. Move.

  Therefore, the illustrated interlocking sliding door device holds the roller shaft 35 of the interlocking roller 25 so as to be rotatable in the depth direction of the opening S by the movable holder 40 of the support means 30 and to be able to advance straight in the axial direction. The shaft tip 35a is constantly biased by the spring 50 obliquely toward the intersection line P where the inner plate surface 41 of the outer door B intersects the upper rail 14, and the circumferential surface 25a of the interlocking roller 25 is lifted by the oblique biasing force. Since it is a structure which presses against both the rail 14 and the inner side plate surface 41 of the outer door B, there is a deviation in the suspension interval of the outer door B with respect to the inner door A as shown by the chain line in FIG. As shown in FIG. 10, there is a deviation in the height position at which the inner door A is suspended, although illustration is omitted, there are variations in processing, assembly, and installation in the doors, the upper rail 14, etc., or there are deformation parts. Even if there is any, it is based on the biasing force of the biasing spring 50. While the shaft tip 35a of the rear shaft 35 is directed to the intersecting line P between the upper rail 14 and the inner plate surface 41 of the outer door B, the interlocking roller 25 is moved between the upper rail 14 and the outer door B which are displaced or deformed. It follows the both sides and moves freely, and the peripheral surface 25a can be always pressed against both the outer door B and the inner plate surface 41 of the upper rail 14 without any gap. Accordingly, when the outer door B is moved at the time of opening and closing, the interlocking roller 25 does not rotate idly because the peripheral surface 25a always hits and presses both the upper rail 14 and the inner plate surface 41 of the outer door B. The outer door B and the upper rail 14 to which the peripheral surface 25a is pressed are rotated by the frictional force of the uniform contact surface to transmit power to the inner door A. As a result, the inner door A and the outer door B are not rattled. It moves smoothly and interlocked, so that the opening / closing operability of the interlocking sliding door can always be kept good.

  By the way, in the illustrated embodiment described above, an example of an interlocking sliding door device in which the support means 30 is attached to the upper part of the inner door A and the peripheral surface 25a of the interlocking roller 25 is pressed against the outer door B and the upper rail 14 is shown. However, the present invention is not limited to the upper part of the inner door. For example, as shown in FIGS. 11 and 12, the support means 30 is attached to the lower part of the inner door A, and the peripheral surface 25 a of the interlocking roller 25 is connected to the outer door B. The inner door A may be moved in conjunction with the outer door B in pressure contact with both of the lower rails 15.

  In the interlocking type sliding door device of the other example shown in the figure, the support means 30 screws the mounting substrate 45 to the door end side wood end surface 37 at the lower part of the inner door A, and the shaft tip 35a of the roller shaft 35 to the lower rail 14. The roller assembly R is tilted toward an intersection line P where the inner plate surface 41 of the outer door B intersects, and the urging force of the urging spring 50 causes the peripheral surface 25a of the interlocking roller 25 to move to the inner plate surface 41 of the outer door B and the lower rail. Assemble it in a state where it is in direct contact with both sides.

  Therefore, in the interlocking type sliding door device of the other example shown in the figure, for example, when closing the fully opened opening S, when the hand 22 is moved from the outside and the outer door B is moved in the opening direction Y, the interlocking roller 25 is The inner door 41 is pressed against both the inner plate surface 41 of the outer door B and the lower rail 14 without any gap, so that the inner door rotates while rotating with the friction force of the uniform contact surface between the outer door B and the lower rail 15 without idling. Power is transmitted to A, so that the inner door A moves smoothly in the same Y direction in the same way as in the above opening without looseness with the outer door B, and the opening S is completely moved. Close.

  In each of the illustrated embodiments described above, the interlocking type sliding door device is incorporated into the door frame W so as to be movable on the lower rail 15 by pivotally supporting the door wheel 20 below the doors A and B, respectively. Although the present invention is applied to the sliding door, the present invention is also applied to a so-called upper door type sliding upper sliding interlocking door in which each door is suspended by the upper rail 14 so as to be movable by pivotally supporting the door wheel on the upper part of both doors. Of course you can.

On the other hand, the upper rail 14 of the guide rail L includes a curtain frame 54 having a U-shaped cross section and a rail body 55. The rail body 55 is a single H-shaped cross section rail, and is formed by projecting an engaging convex portion 55c parallel to the lower flange portion 55b on the other side upward with respect to the upper flange portion 55a on one side. The upper rail 14 is integrally formed by fixing the upper flange portion 55a of the rail body 55 to the inner surface of the substrate portion 54a of the curtain plate frame 54, and the curtain plate frame 54 is formed on the upper frame 12 on the outer surface of the substrate portion 54a. It adheres to. And the door pulley 49 is each engaged with the engagement convex part 55c of the rail main body 55, and it has the structure which suspended each door by the upper rail 14 so that a movement in the opening / closing direction was possible.

The inner plate surface 41 and the lower flange surface 56 of the upper rail 14 are directly applied to and assembled in a pressure contact state.

  FIG. 15 and FIG. 16 show an example in which the interlocking type sliding door device of the present invention is applied to another upper door type upper suspension interlocking sliding door. In the example of the top door type suspended suspended sliding door shown in the figure, an L plate bracket 51 is erected on the upper end surface 18 of both doors A and B with the same depth direction outside, and the door wheel 49 is pivoted by these bra rackets 51. The upper end surface 18 is supported. On the other hand, the upper rail 14 of the guide rail L includes a curtain plate frame 59 having a U-shaped cross section and two rail bodies 60 and 61. Each of the rail bodies 60 and 61 is a U-shaped rail, and the engaging convex portions 60c and 61c parallel to the lower flange portions 60b and 61b on the other side are directed upward in the figure with respect to the upper flange portions 60a and 61a on one side, respectively. Projected to The upper rail 14 is integrally formed by fixing the upper flange portions 60a and 61a of the rail bodies 60 and 61 to the inner surface of the substrate portion 59a of the curtain plate frame 59, and on the outer surface of the substrate portion 59a. Are fixed to the upper frame 12 and arranged side by side. The door 49 is engaged with the engaging projections 60c and 61c of the rail bodies 60 and 61, and the doors A and B are suspended by the upper rail 14 so as to be movable in the opening and closing direction.

  Therefore, in the interlocking type sliding door device of the other example shown in the figure, the support means 30 is screwed to the top end side of the door 37 on the upper end of the inner door A, and the shaft tip 35a of the roller shaft 35 is connected to the upper rail. 14, the roller assembly R is inclined toward the intersection line P where the inner plate surface 41 of the outer door B intersects with the surface connecting the lower flange surface 65 of the outer door B, and the peripheral surface 25 a of the interlocking roller 25 is removed by the urging force of the urging spring 50. The door B is assembled in a state where it is in direct contact with both the inner plate surface 41 of the door B and the lower flange surface 65 of the upper rail 14.
