Description

The present invention relates to a method for manufacturing a panel body for fittings in which a honeycomb core and a frame are sandwiched between a pair of face members, and a panel body for fittings.

The panel body is used, for example, as a shoji of a fitting, an opening/closing body, or a door panel. A pair of face members of the panel body are fixed to the core body and provided on both surfaces of the panel body. A honeycomb core may be provided between a pair of face members, and the honeycomb core is sandwiched between the pair of face members. Furthermore, there is conventionally known a door panel in which a honeycomb-shaped core material is filled between a pair of face plates and a door handle as an accessory is attached (see Patent Document 1).

In the conventional door panel described in Patent Document 1, in order to attach a door handle, it is necessary to form a mounting hole in a pair of face plates. However, when processing the mounting holes, the core material is processed together with the face plate at the location where the mounting holes are formed. Therefore, the processing waste of the face plate and the processing waste of the core material are mixed, and the amount of processing waste becomes large. Additionally, there is a possibility that processing waste may remain inside the door panel. When the core material is made of paper, the processed surface of the core material becomes rough, and the possibility that processing waste remains inside the door panel increases.

A mounting hole 21 is provided. The pair of face materials 20 are plate-shaped surface materials (face plates) of the panel body 3, and are arranged on both surfaces of the panel body 3 in the thickness direction R.

The core body 30 is a portion (core material) that becomes the core of the panel body 3, and is arranged between the pair of face materials 20 in the thickness direction R of the panel body 3. The pair of face materials 20 are located on both sides of the core body 30 in the thickness direction R of the panel body 3, and are arranged with the core body 30 sandwiched between them. The face material 20 is bonded to both sides of the core body 30 with an adhesive and joined to the core body 30. Thereby, the pair of face materials 20 are each fixed to the core body 30. Both surfaces of the core body 30 are surfaces located on both sides of the core body 30 in the thickness direction R of the panel body 3, and are covered with the face material 20.

The core body 30 has a frame body 40 sandwiched between a pair of face members 20, a horizontal bar 41, and a honeycomb core 50. The frame body 40 is a frame-shaped core material, and is arranged between the pair of face members 20 along the outer peripheral edge (outer periphery) of the face members 20. The horizontal beam 41 is a horizontal member (horizontal core) extending in the left-right direction. The honeycomb core 50 is a core material of a honeycomb structure, and is formed in a honeycomb shape. The horizontal bars 41 and the honeycomb core 50 are arranged inside the frame body 40 and housed inside the frame body 40, respectively. The frame body 40, horizontal bar 41, and honeycomb core 50 of the core body 30 are formed to have the same thickness when comparing the thicknesses in the thickness direction R of the panel body 3. The pair of face members 20 are fixed to the frame body 40, the horizontal bar 41, and the honeycomb core 50 with the frame body 40, the horizontal bar 41, and the honeycomb core 50 interposed therebetween.

The frame body 40 forms an arrangement space 5 for a honeycomb core 50. The arrangement space 5 is a space for arrangement of the honeycomb core 50, and the honeycomb core 50 is arranged in the arrangement space 5 between the pair of face members 20. The arrangement space 5 is a space inside the frame 40, and is partitioned inside the frame 40 by the frame 40. The frame 40 surrounds the arrangement space 5 and the honeycomb core 50 within the arrangement space 5. The arrangement space 5 is an opening that penetrates the frame 40 in the thickness direction R of the panel body 3, and is open in both directions in the thickness direction R of the panel body 3. The pair of face members 20 sandwich the arrangement space 5 between them, and cover the entire arrangement space 5. The arrangement space 5 is closed by face materials 20 on both sides of the panel body 3 in the thickness direction R.

The accessory part 4 is a mounting part attached to the panel body 3, and is provided attached to the panel body 3. The mounting hole 21 is a hole for mounting the accessory part 4, and is formed to penetrate through at least one of the pair of face members 20 (one face member 20 or both face members 20). has been done. The accessory part 4 is attached to the attachment hole 21 of at least one of the pair of face members 20 and at least one of the face members 20 . The attachment hole 21 is formed in at least one of the pair of face members 20 and opens into the arrangement space 5 .

Here, the accessory part 4 is a handle of the panel body 3, and is attached to both of the pair of face materials 20, and is provided on both sides of the panel body 3 in the thickness direction R. Therefore, the attachment hole 21 of the accessory part 4 is formed in both of the pair of face members 20. The attachment hole 21 penetrates a portion of the panel body 20 that covers the arrangement space 5 in the thickness direction R of the panel body 3, and opens on both sides of the panel body 20. In the thickness direction R of the panel body 3, the attachment hole 21 opens to the outside of the panel body 3 and the arrangement space 5, and is open toward the outside of the panel body 3 and the arrangement space 5.

4 to 6 are diagrams showing the manufacturing procedure of the panel body 3 of the fittings 1 of the first embodiment, and show the panel body 3 at each stage of manufacture as seen from the front.
As shown in the figure, the frame body 40 is a frame formed in a rectangular shape, and has a plurality of frames 42 to 44 (an upper frame 42, a lower frame 43, and a pair of vertical frames 44) combined with each other. . The upper stile 42, the lower stile 43, and the pair of vertical stile 44 are stile materials that constitute the stile body 40. The upper stile 42 and the lower stile 43 are horizontal stile located at the upper and lower parts of the frame body 40, and extend in the left-right direction along the upper and lower edges of the arrangement space 5. The pair of vertical frames 44 are side frames located on the left and right sides of the frame body 40, and extend in the vertical direction along the left and right side edges of the arrangement space 5. The ends of the upper stile 42, the lower stile 43, and the left and right vertical stile 44 are connected to form four frames 42-44.

The upper stile 42 and the lower stile 43 are a pair of horizontal members (horizontal cores), and the pair of vertical stiles 44 are a pair of vertical members (vertical cores). The frame body 40 forms a rectangular arrangement space 5 with an upper frame 42, a lower frame 43, and a pair of vertical frames 44. One horizontal frame 41 is arranged in the arrangement space 5 and connected to a pair of vertical frames 44 of the frame body 40. The horizontal beam 41 crosses the arrangement space 5 in the left-right direction, spans the pair of vertical frames 44, and divides the arrangement space 5 in the vertical direction.

The arrangement space 5 within the frame body 40 is divided into two arrangement spaces 5A and 5B (an upper arrangement space 5A and a lower arrangement space 5B) by a horizontal beam 41. The upper arrangement space 5A is an arrangement space 5 defined above the horizontal bar 41, and the lower arrangement space 5B is an arrangement space 5 defined below the horizontal bar 41. The horizontal beam 41 is located between the upper arrangement space 5A and the lower arrangement space 5B.

The honeycomb core 50 is a paper honeycomb core made of paper, and is formed of a constituent material 51. Further, the honeycomb core 50 is an aggregate of a large number of cylindrical cells 52. The constituent material 51 is a paper band material that constitutes the honeycomb core 50, and is combined in a honeycomb shape to constitute a honeycomb structure. The cell 52 is formed into a hollow shape by an annular (cylindrical) component 51 and has a void 53 . The voids 53 penetrate the cells 52 and the honeycomb core 50 in the thickness direction R of the panel body 3 and are open in both directions in the thickness direction R of the panel body 3. The constituent material 51 is a wall material of the cell 52 and surrounds the void 53 of the cell 52.

The honeycomb core 50 and a large number of cells 52 are filled in the arrangement space 5, and the large number of cells 52 are gathered in parallel in the vertical and horizontal directions. The shape of the cells 52 is not particularly limited, and the cells 52 may have an annular shape (for example, a hexagonal shape, a square shape, a triangular shape, another polygonal shape, a circular shape, an elliptical shape) when viewed from the thickness direction R of the panel body 3. It is formed. In this way, the cells 52 of the honeycomb core 50 can be formed into various cylindrical shapes as long as they are cylindrical. Here, the cell 52 is a rectangular tube portion formed in a rectangular shape when viewed from the thickness direction R of the panel body 3.

When manufacturing the panel body 3, the frame body 40 is assembled and the horizontal beams 41 are attached to the frame body 40. Further, the frame body 40 is placed on the workbench. Subsequently, the honeycomb core 50 is placed in the arrangement space 5 of the frame body 40, and the honeycomb core 50 is spread and arranged within the arrangement space 5. Thereby, the honeycomb cores 50 are arranged over the entire arrangement space 5, and the arrangement space 5 is filled with the honeycomb cores 50. At that time, the honeycomb cores 50 are arranged in the arrangement spaces 5 above and below the horizontal beams 41 (upper arrangement space 5A, lower arrangement space 5B), and the honeycomb cores 50 are accommodated in the arrangement spaces 5. The horizontal bar 41 is placed between the honeycomb core 50 (upper honeycomb core) in the upper arrangement space 5A and the honeycomb core 50 (lower honeycomb core) in the lower arrangement space 5B.

Next, the space jig 6 is placed in the opening 60 of the attachment hole 21 formed in the face material 20 within the placement space 5 (see FIG. 4). The opening location 60 of the attachment hole 21 is a location where the attachment hole 21 in the arrangement space 5 opens. The space jig 6 is a jig (space forming member) for forming the space 7 in the arrangement space 5, and is formed larger than the attachment hole 21. Using the void space jig 6, the honeycomb core 50 (constituent material 51) located at the location where the void space jig 6 is placed (placement location) is removed. As a result, the honeycomb core 50 is removed from the opening 60 of the attachment hole 21. In this state, the cavity jig 6 is taken out from the arrangement space 5 and the opening 60 of the mounting hole 21, and a cavity 7 without the honeycomb core 50 is formed in the opening 60 of the mounting hole 21 (see FIG. 5). .

A space 7 is secured at the opening 60 of the mounting hole 21 using the space jig 6 . The cavity 7 is formed larger than the attachment hole 21. The honeycomb core 50 and the component 51 are located around the cavity jig 6 and the cavity 7. In FIG. 4 and FIG. 5, the component 51 located around the space jig 6 and the space 7 is schematically shown by a chain line.

When forming the cavity 7, the cavity jig 6 is placed in the opening 60 of the attachment hole 21 while removing the component 51 of the honeycomb core 50 from the opening 60 of the attachment hole 21 in the arrangement space 5. At this time, the constituent material 51 is pushed away from the location where the void jig 6 is arranged, and the constituent material 51 and the honeycomb core 50 are deformed along the outer periphery of the void jig 6. Further, a part or all of the component 51 located at the location where the cavity jig 6 is arranged may be removed from the honeycomb core 50. The structural material 51 and the honeycomb core 50 are deformed to the outside of the void space jig 6, and the component material 51 and the honeycomb core 50 are arranged around the void space jig 6.

Here, the attachment hole 21 is formed in the face material 20 so as to open at a corner portion 61 of the arrangement space 5. Therefore, the opening 60 of the attachment hole 21 is located at a corner 61 of the arrangement space 5. The corner portion 61 of the arrangement space 5 is a corner portion located at a location where the horizontal rail 41 connects to the vertical stile 44 in the upper arrangement space 5A or the lower arrangement space 5B (here, the lower arrangement space 5B). In the arrangement space 5 (lower arrangement space 5B), the empty space jig 6 is placed in the corner part 61 of the arrangement space 5 where the horizontal beam 41 connects to one vertical stile 44, and the corner part of the arrangement space 5 is A void 7 is formed at the opening 60 of the attachment hole 21 located at 61.

The space jig 6 contacts the horizontal beam 41 and the vertical stile 44, fits into the corner part 61 of the arrangement space 5, and fills the corner part 61 of the arrangement space 5. The corner part of the honeycomb core 50 located at the corner part 61 of the arrangement space 5 is removed from the opening part 60 of the mounting hole 21 by the space jig 6. At this time, the corner portions of the honeycomb core 50 (corner portion constituent members 51) are deformed to the outside of the void space jig 6. Thereby, the corner portion of the honeycomb core 50 is deformed along the outer circumferential portion of the cavity jig 6, and a recess portion 54 is formed in the corner portion of the honeycomb core 50. The cavity jig 6 fits into the recess 54. The cavity jig 6 is taken out from the corner part 61 of the arrangement space 5 and the recess 54, and the cavity 7 is formed at the opening part 60 of the attachment hole 21 located at the corner part 61 of the arrangement space 5 and the corner part of the honeycomb core 50. do.

Before or after forming the void space 7 in the opening part 60 of the attachment hole 21, multiple parts of the edge of the honeycomb core 50 (constituent material 51 located at the edge) are attached to the frame body 40 and the horizontal bar 41, and the honeycomb The core 50 is fixed to the frame body 40 and the horizontal beam 41. By fixing the honeycomb core 50, the void space 7 is maintained. Alternatively, the hollow space 7 may be maintained by attaching the constituent members 51 of the honeycomb core 50 located around the hollow space 7 to the vertical frames 44 and horizontal bars 41 of the frame body 40. The honeycomb core 50 is placed in the arrangement space 5 in a state excluded from the opening 60 of the attachment hole 21 to form a void 7 at the opening 60 of the attachment hole 21 in the arrangement space 5.

With the cavity 7 formed in the opening 60 of the mounting hole 21, the core body 30 including the frame body 40, the honeycomb core 50, and the horizontal bar 41 is sandwiched between the pair of face members 20, and the pair of faces The material 20 is fixed to the core body 30 (see FIG. 6). Thereby, the pair of face members 20 are fixed to the frame body 40, honeycomb core 50, and horizontal bar 41 that are sandwiched between them. When fixing the face material 20, adhesive is applied to the core body 30 on both sides of the panel body 3 in the thickness direction R, and the core body 30 is arranged between the pair of face materials 20. The core body 30 is sandwiched between a pair of face materials 20, and the pair of face materials 20 are bonded to the core body 30 with an adhesive. The pair of face members 20 are joined and fixed to both sides of the frame body 40, honeycomb core 50, and horizontal bar 41 of the core body 30.

Next, at least one of the pair of face members 20 is drilled to form the attachment hole 21 toward the empty space 7 of the opening portion 60 of the attachment hole 21 in the arrangement space 5 . Thereby, the attachment hole 21 is formed in at least one of the pair of face members 20 so as to open into the space 7 of the opening location 60 of the attachment hole 21 . Furthermore, the attachment hole 21 opens into the empty space 7 of the opening location 60 of the attachment hole 21 located at the corner portion 61 of the arrangement space 5 . Since the honeycomb core 50 is located outside the opening 60 of the mounting hole 21, even if the mounting hole 21 opens into the cavity 7, it is not processed following the mounting hole 21, and is processed at a position around the mounting hole 21. will be placed in

Here, mounting holes 21 are formed in both of the pair of face members 20, each opening into the cavity 7 of the opening location 60 of the same mounting hole 21. The mounting holes 21 of the pair of face members 20 are formed to open into the common cavity 7. Thereby, a through hole 62 is formed in the panel body 3. The through hole 62 consists of the attachment holes 21 of the pair of panel members 20 and the space 7 located between the attachment holes 21 of the pair of panel members 20, and penetrates through the panel body 3 in the thickness direction R. After that, the accessory parts 4 are attached to each of the attachment holes 21 of the pair of face members 20, and the accessory parts 4 are attached to the attachment holes 21.

As explained above, by forming the attachment hole 21 so as to open into the cavity 7, the attachment hole 21 can be formed in the face material 20 without processing the honeycomb core 50. Further, as the attachment hole 21 is processed, only processing waste of the face material 20 is generated, and processing waste of the honeycomb core 50 is not generated. Therefore, the processing waste of the face material 20 does not mix with the processing waste of the honeycomb core 50, and the processing waste of the honeycomb core 50 does not remain inside the panel body 3. The component 51 of the honeycomb core 50 located around the opening 60 of the mounting hole 21 receives the processing waste of the face material 20 and suppresses the processing waste of the face material 20 from entering the inside of the panel body 3. I can do it. Even when the processing waste of the face material 20 enters the inside of the panel body 3, the processing waste of the face material 20 can be easily removed from the inside of the panel body 3.

The pair of vertical frames 44 can be restrained by the horizontal beams 41, and deformation of the vertical frames 44 in the left-right direction can be suppressed. Further, the space jig 6 is arranged at a corner portion 61 of the arrangement space 5. Therefore, when forming the mounting hole 21 opening in the corner part 61 of the arrangement space 5, the cavity jig 6 can be accurately and easily placed at the opening part 60 of the mounting hole 21 in the arrangement space 5, and the mounting hole The void space 7 can be reliably formed at the opening location 60 of 21. By deforming the corner portions of the honeycomb core 50, the voids 7 can be easily formed at the openings 60 of the attachment holes 21.

The respective mounting holes 21 of the pair of face members 20 open into the same cavity 7. Therefore, the attachment holes 21 can be easily formed at the same location on the pair of face members 20 without processing the honeycomb core 50. Further, the through hole 62 including the two attachment holes 21 can be easily formed in the panel body 3.

Note that the mounting hole 21 of the face material 20 may be formed to open at a location other than the corner portion 61 of the arrangement space 5 (for example, an edge, or a location closer to the center than the edge). The edge of the arrangement space 5 is a portion of the arrangement space 5 along the frame 40 or the horizontal beam 41. When the attachment hole 21 is formed by opening at the edge of the arrangement space 5, the opening portion 60 of the attachment hole 21 is located at the edge of the arrangement space 5. Furthermore, when forming the empty space 7, the empty space jig 6 is placed within the arrangement space 5 at the edge of the arrangement space 5. The space jig 6 contacts the frame body 40 or the horizontal beam 41.

The edge of the honeycomb core 50 located at the edge of the arrangement space 5 is removed from the opening 60 of the mounting hole 21 by the space jig 6. At this time, the edge of the honeycomb core 50 (the edge component 51) is deformed to the outside of the cavity jig 6. Thereby, the edge of the honeycomb core 50 is deformed along the outer periphery of the cavity jig 6, and a recess is formed in the edge of the honeycomb core 50. The cavity jig 6 fits into the recess. The cavity jig 6 is taken out from the edge of the arrangement space 5 and the recess, and the cavity 7 is formed at the opening 60 of the attachment hole 21 located at the edge of the arrangement space 5 and the edge of the honeycomb core 50. The attachment hole 21 opens into the empty space 7 at the opening location 60 of the attachment hole 21 located at the edge of the arrangement space 5 . By deforming the edge of the honeycomb core 50, the void 7 can be easily formed at the opening 60 of the attachment hole 21.

The honeycomb core 50 has open portions provided at corners and edges. The open portions of the honeycomb core 50 are the corner portions and edges of the honeycomb core 50 located outside the cells 52, and are open toward the outside of the honeycomb core 50. In the open portion of the honeycomb core 50, the constituent material 51 protrudes from the cells 52 toward the outside of the honeycomb core 50, and the constituent material 51 forms an open space. When forming the void 7 at the corner or edge of the honeycomb core 50, the void jig 6 may be fitted into the open portion (open space) of the honeycomb core 50. In this case, the open portion of the honeycomb core 50 is deformed along the outer circumference of the jig 6 for void space to form the void space 7 in the open portion of the honeycomb core 50 .

Note that the fitting 1 may be fittings other than sliding doors and doors, and the panel body 3 can be used for panel bodies of various fittings. Further, the accessory parts 4 are not limited to the pull and the handle, but may be other parts attached to the panel body 3 (for example, a lock, an operating part, a small window). One accessory part 4 may be attached to one attachment hole 21, or a plurality of accessory parts 4 may be attached to one attachment hole 21. One attachment hole 21 may be formed in the panel 20, or a plurality of attachment holes 21 may be formed in the panel 20. The horizontal bar 41 may not be provided on the core body 30.
