Description

  The present invention relates to a partition door used for partitioning a space such as between rooms and between a room and a closet, a bending member used therefor, and a method for manufacturing the bending member.

  Conventionally, a partition door made of a door-to-door or the like has been used to partition a room between rooms, for example, a Western-style room and a Japanese-style room, or a space between a room and a closet. . In such a partition door, generally, a horizontal braid extending in the left-right direction and a vertical braid extending in the vertical direction are arranged at regular intervals inside the surrounding bone formed in a square frame shape. The core material which consists of the frame body assembled | attached by the grid | lattice form is used. Paste the backing paper on the front and back surfaces of the core material, and then apply the decorative backing paper with a pattern on the surface (outer surface) of both of the liner papers. A door frame is formed by attaching a frame-shaped peripheral edge.

Such a door is often warped due to a difference in contraction force between the backing paper and the backing paper attached to the front surface side and the backing paper and the backing paper attached to the back surface side. For this reason, a door-tower with a structure for preventing warping has been devised (for example, see Patent Document 1). In this Toba, a wooden board is attached to the front and back of the core material, a Western-style cosmetic plastic sheet or Western-style decorative paper is attached to the surface of the front wooden board, and the above-mentioned Western-style is applied to the surface of the wooden board on the back side. A plastic sheet or paper of the same type as a decorative plastic sheet or Western-style decorative paper is pasted. Further, a front plate with Japanese-style decorative paper pasted on the surface is attached to the front side of the plastic sheet or paper on the back side wooden board so as to be misaligned.
JP 7-217326 A

  However, in the above-mentioned Toba, a Japanese-style decorative paper is attached to the surface in addition to the wooden boards attached to the front and back of the core material and the Western-style plastic sheets and Western-style decorative papers attached to the surfaces of both wooden boards. Since a plate is required, the number of members increases and the structure becomes complicated. This causes a problem that the manufacturing is troublesome and the cost is increased. In addition, there is a problem that warpage generated on the front plate cannot be prevented. In addition, even if the same type of sheet or paper is attached to the front and back of the core material, the warp may be warped due to the difference in temperature and humidity between the Western-style room and the Japanese-style room. There is also a problem that warping in some cases cannot be prevented.

  The present invention has been made in order to address the above-described problems. The object of the present invention is to simplify the structure without increasing the number of members, thereby facilitating manufacturing and reducing costs, and ensuring the occurrence of warpage. It is providing the partition door which can be prevented easily, the bending member used for it, and the manufacturing method of a bending member.

  In order to achieve the above-described object, the structural feature of the partition door according to the present invention is a partition door configured by sticking a sheet body to the front and back of a frame-shaped core material, and constitutes the core material. At least one member among the members is formed by curving in the front and back direction of the core material, and is pasted on the front and back surfaces of the core material due to the difference in temperature and humidity of both side spaces of the partition door at the place where the partition door is installed. Considering the contraction force generated in both sheet bodies, the large contraction force is directed to the surface of the sheet body where the curved member protrudes toward the sheet body where a large contraction force is generated. In addition to pasting a sheet body in which the above occurs, the other sheet body is pasted on the other surface of the core member, and after the partition door is installed, there is no warping.

  As described above, in the partition door according to the present invention, as in the case of a conventional door rod, warpage does not occur by pasting the same type of plastic sheet having the same shrinkage force on the front and back of the core material, and further, on the back side. Rather than increasing the number of components, such as attaching a front plate with Japanese-style decorative paper attached to cover a plastic sheet in a movable state, warping occurs with a simple structure without increasing the number of components. It is possible to prevent.

  That is, in the present invention, due to the temperature and humidity difference between the space portions on both sides of the partition door at the place where the partition door is installed, the two sheets attached to the front and back of the core material on the side where a large contractive force is generated. The sheet body is attached to the surface of the core member from which the curved member protrudes. In this case, the two sheet bodies attached to the front and back of the core material may be the same or different. In short, the surface of the partition door that contracts due to temperature and humidity may be the surface on which the curved member protrudes, so that the partition door after installation does not warp.

As described above, in the partition door according to the present invention, it is possible to prevent the occurrence of warpage with a simple operation of forming a predetermined member in a curved state in advance, instead of adding a new member. The structure can be reduced and the manufacturing can be facilitated and the cost can be reduced. The sheet body in this case includes various sheet-like materials such as paper, thin plate, plastic sheet, vinyl sheet, and plywood. In addition, the partition door in the present invention includes a panel-like door that partitions a space portion between doors and doors, a closet, and a fitting used for a storage space between rooms. Shall be.

  Another structural feature of the partition door according to the present invention is that the curved member is a member along the longitudinal direction of the core material among the members constituting the core material. The warp that occurs in the partition door usually appears along the longitudinal direction when the core material and thickness are the same, so the member along the longitudinal direction is curved in advance to form the partition door. When used, it can be in a state without warping. In addition, when the partition door is a door cage, the member along the longitudinal direction formed by bending is a standing rail of a surrounding bone or a middle rail arranged vertically inside the surrounding bone, and the partition door is a forehead part If it is a door provided with, it shall be the part extended in the up-down direction arrange | positioned at the right-and-left both sides of a forehead part. Moreover, when a partition door is a horizontally long thing, it shall be a member extended in a horizontal direction.

  Further, another structural feature of the partition door according to the present invention is a partition door configured by sticking different sheet bodies to the front and back of the frame-shaped core material, the members constituting the core material. At least one member along the longitudinal direction of the core material is formed by curving in the front and back directions of the core material, and among the different sheet bodies, a sheet body that generates a large shrinkage force due to drying after pasting is formed. This is because the curved member of the material is attached to the protruding surface and the other sheet member is attached to the other surface of the core material so as not to warp.

  In the partition door according to the present invention, the sheet body that generates a large contraction force by drying after pasting out of the two types of sheet bodies that have different contraction forces when contracting (in a relatively large contraction force, When the two types of sheet bodies are stretched together, the center side in the longitudinal direction of the curved member is positioned on the surface of the core material to which the smaller stretching force is attached) so that the surface projecting from the upper and lower ends is located. Yes. Therefore, the curved member is corrected by the expansion / contraction force of both sheet bodies, and the partition door is in a state without warping.

  Another structural feature of the partition door according to the present invention is that the core member is formed in a frame shape including a vertical member and a horizontal member such as a surrounding bone, a middle rail, and a forehead. According to this, it is possible to select an arbitrary member to be curved from surrounding bars, middle bars, and the like of the surrounding bones, so that the design can be widened.

  Further, in the partition door according to the present invention, when the sheet body is attached to the core material by the adhesive and the adhesive dries, the curvature of the curved member is taken into account the contraction force generated in each sheet body. Can be determined. According to this, when a partition door is manufactured, it is possible to obtain a good partition door with little or no warpage. In this case, it is preferable to consider the type and amount of the adhesive used and the drying speed. Furthermore, the curvature of the curved member can be determined in consideration of the temperature and humidity of the space where the partition door is arranged. According to this, after manufacturing a partition door, a state without a curvature can be maintained.

  In addition, another structural feature of the partition door according to the present invention is that the core member has a lattice frame-like, plate-like or mesh-like core portion inside a square frame-like surrounding bone made up of a standing rail and a horizontal rail. It is that they are assembled and formed.

  As the core portion, a honeycomb paper honeycomb core, a lattice frame-like braid core formed by assembling a horizontal braid extending in the left-right direction and a vertical braid extending in the vertical direction into a lattice shape, foamed polystyrene, particle board, etc. A plate-like core portion or the like is used. In addition, it is preferable to use a braided core from the viewpoint of strength, air permeability, and the like. In this case, it is preferable to use wood or a wood-based material as a material constituting the horizontal braid and the vertical braid. Thereby, a better partition door can be obtained. In this case, the left and right standing bars of the surrounding bone constitute a curved member. However, it is also possible to provide a middle bar between the compatible bars to form a curved member. In this case, the left and right standing bars of the surrounding bone may be curved, or the middle bar may be curved. Further, the number of middle rails may be one or two or more.

  In addition, another structural feature of the partition door according to the present invention is that the partition door is a door, and one of the sheet bodies that generates a large contraction force after being attached is subjected to moisture-proof treatment. In other words, the other sheet of the sheet bodies is formed by attaching a vinyl cloth to the surface of the paper board that has been subjected to the moisture-proof treatment.

  In a conventional door, a plywood such as a veneer is attached to the front and back of the core material, a paper is attached to the surface of one plywood, and a vinyl cloth is attached to the surface of the other plywood, When such a plywood is used, the accretion contained in the plywood may ooze out and stains may appear on the paper. Further, since the plywood easily absorbs moisture, the plywood shrinks when dried and the warp tends to warp. For this reason, it is possible to reduce the expansion and contraction of the paper and vinyl cloth by sticking the paper and vinyl cloth to the core material through a paper board that has been subjected to moisture-proof treatment, and the protrusion of the central part of the curved member The amount can be reduced. As a result, the adjustment for preventing the warpage of the door is facilitated, and a door with higher flatness can be obtained. In this case, examples of the paper include a bird paper, a new bird paper, a Kamishi bird paper, and a saori paper.

  Furthermore, another structural feature of the partition door according to the present invention is that it is installed between a Western-style room and a Japanese-style room, and one sheet body that generates a large shrinkage force after being attached is attached to the surface of the core material on the Japanese-style room side. The other sheet body is to be stuck to the surface of the core material on the Western-style room side. According to this, for example, by attaching a sheet body containing vinyl cloth to the surface of the Western-style room in the core material, and attaching a sheet body containing paper to the Japanese-style room side of the core material, the texture according to each room Can be issued. For example, the paper is made of bird's paper or the like, and the vinyl cloth is made of a decorative sheet printed with a wood grain pattern.

  Further, another structural feature of the partition door according to the present invention is that the protruding amount of the central portion in the longitudinal direction of the curved member before the sheet body is attached to the core member is in the vertical direction of the curved member. The length is 0.10 / 100 to 1.25 / 100.

  That is, when the height of the curved member is 2 m, it is preferable that the protruding amount of the central portion of the member is about 2 to 25 mm. The warpage that occurs when using two types of sheet bodies that differ greatly in shrinkage among commonly used materials such as paper and vinyl cloth, is the case when using wood that is normally used for core members If the protruding amount of the central side portion of the curved member is set to about 25 mm, a partition door without warping can be obtained when assembled.

  Therefore, the member using the material which cannot obtain the partition door without a curvature unless the protrusion amount beyond this is set is not suitable as the material of the core member. For example, wood cut out from hardwood is not suitable as a material for the core member, and as a material used for the core member, it is preferable to use a laminated material such as wood cut from softwood or parallel plywood. Further, even when two types of sheet bodies that do not have much difference in contraction force are used, some warping occurs in the core material, so it is necessary to form a curved portion in a predetermined member. If the height of the partition door is set to 2 m and the height of the partition door is set to about 5 mm, a good partition door without warping can be obtained.

  In addition, a structural feature of the method for manufacturing a bending member according to the present invention is a method for manufacturing the bending member for manufacturing the bending member, wherein the thickness is set to be substantially the same as the thickness of the bending member. While the curved portion forming step of forming one side of the plate body into a predetermined curved shape using a processing device, and the curved portion formed in the curved portion forming step are relatively moved along the guide portion, And a curved member forming step of sequentially forming the plate body into a curved member having a constant width by cutting the plate body with a guide portion and a cutting blade installed at a predetermined interval.

  In this way, the cutting blade is cut while relatively moving in a state in which one side of the plate body for taking out the bending member is cut into a curved shape forming the bending member, and the curved cutting surface is along the guide portion. By cutting with, the bending member can be taken out with a simple operation. In this case, after the first bending member is taken out, one side of the plate is a curved cut surface having the same shape as the first bending portion. Individual bending members are removed. As a cutting device in this case, an NC processing machine or the like can be used, and as a device provided with a guide portion and a cutting blade, a woodworking band saw, a cutting device provided with a circular saw, or the like can be used. In cutting, the plate body may be moved with respect to the cutting blade, or the cutting blade may be moved with respect to the plate body.

Yes.

  Further, as shown in FIG. 1, a paper 12 made of a bird's child paper having a pattern (not shown) applied to the surface is attached to the inner portion of the peripheral edge 11 on the surface of the door 10 located on the side of the Japanese-style room. A round handle 13 having a central portion formed as a recess is attached to one side (left side in FIG. 1) in the left-right direction at the approximate center in the vertical direction. FIG. 2 shows a surface located on the Western-style room side of the toad 10, and a vinyl cloth having a wood grain pattern print (not shown) on the surface is provided on the inner portion of the peripheral edge 11 of the toshi 10. A decorative sheet 14 is attached. Then, an oval puller 15 having a central portion formed in a concave portion and elongated in the vertical direction is attached to the other side (right side in FIG. 2) in the horizontal direction at the approximate center in the vertical direction of the decorative sheet 14 of the doorpad 10. ing.

  The interior of the door 10 is configured as shown in FIGS. 3 and 4. That is, on the inner side of the peripheral edge 11, a rectangular frame-shaped perimeter composed of standing bars 16a and 16b as curved members of the present invention extending in the vertical direction on both the left and right sides and horizontal bars 16c and 16d extending in the horizontal direction on both the upper and lower sides. Bone 16 is formed. A plurality of horizontal braids 17a extending in the left-right direction are stretched on the inner surfaces of the uprights 16a, 16b in the interior of the door rod 10 at regular intervals in the vertical direction. A plurality of standing braids 17b extending in the up-and-down direction with a constant interval in the left-right direction are spanned. The upright bars 16a and 16b, the horizontal bars 16c and 16d, the horizontal beam 17a and the vertical beam 17b constitute a core member 18. Further, the horizontal braiding 17a and the vertical braiding 17b constitute a core portion according to the present invention.

  Reinforcing corner plates 19a are attached to the insides of the corners of the four corners of the surrounding bone 16 composed of the upright bars 16a and 16b and the horizontal bars 16c and 16d, respectively. In addition, a square plate-like pulling anchor plate 19b is attached to a portion of the core member 18 where the pullers 13 and 15 are attached. Concave portions corresponding to the shapes of the pull handles 13 and 15 are formed on both sides of the pull handle anchor plate 19b, respectively. The pull handles 13 and 15 are attached to the door cage 10 by engaging with the concave portions of the pull handle anchor plate 19b. It has been.

  And the paperboards 21a and 21b to which moisture-proof processing was given are stuck on the front and back both surfaces (surface located in the Japanese-style room side and the Western-style room side) of the core material 18, respectively. These paperboards 21a and 21b are composed of a plurality of layers laminated by sticking a polyethylene sheet or kraft paper on both sides of the super water-resistant paper, and have characteristics that hardly absorb moisture. Then, the above-mentioned backing paper 12 is attached to the surface of the paperboard 21a, and the decorative sheet 14 is attached to the surface of the paperboard 21b.

  Furthermore, the peripheral edge 11 is attached to the outer side surface of the core material 18 in this state, and the door rod 10 is configured. In addition, the sheet | seat body based on this invention is comprised by the paper 12, the decorative sheet 14, and the paperboards 21a and 21b, the thickness of the paper 12 is 0.2-0.3 mm, and the thickness of a decorative sheet is 0.4-. The thickness of 0.6 mm and the paperboards 21 a and 21 b is set to 1.5 mm.

  Below, the manufacturing method of the door-tower 10 comprised as mentioned above is demonstrated. The manufacturing of the door towel 10 is started by first forming various materials constituting each part of the door blade 10 into a predetermined shape designed in advance by processing. In this case, wood such as cedar and hinoki is used as the material used for the peripheral edge 11, the peripheral bone 16, the horizontal braiding 17a, the vertical braiding 17b, the corner plate 19a, and the pulling anchor board 19b. Each material to be processed is processed into a shape of a designed dimension.

  In this case, the standing bars 16a and 16b are formed in a previously curved shape as shown in FIG. For example, when the height a of the standing bars 16a and 16b is 2000 mm, the length of the warp b (the length in which the central portions of the standing bars 16a and 16b protrude in the left-right direction in FIG. 5) is set to about 10 mm. FIG. 5 shows the warp b larger than the actual value in order to make it easy to understand the curved state. Further, in order to form the upright bars 16a and 16b, first, one side 22a of the large rectangular wooden board 22 shown in FIG. 6 (a size capable of forming a plurality of upright bars 16a and 16b by cutting) is cut into a curved shape. By doing. As this wooden board 22, it is preferable to use a parallel plywood.

  This cutting can be performed using, for example, a CNC router (not shown), and is shown in FIG. 7 by cutting one side 22a of the wooden board 22 along the two-dot chain line c shown in FIG. A curved portion 23a is formed. The CNC router includes a base part that can move in the front-rear direction and the left-right direction with the wooden board 22 fixed, and a cutting blade installed above the base part, and moves the base part in a predetermined direction. The curved portion 23a can be formed by cutting one side 22a of the wooden board 22 with a cutting blade.

  Next, the standing board 16a (, 16b) is formed by cutting the wooden board 22 formed with the curved part 23a from the curved part 23a at a constant interval. This cutting can be performed, for example, by cutting the wooden board 22 against the two-dot chain line d shown in FIG. 7 using the band saw 24 shown in FIG. The lower side portion of the band saw 24 includes a base 25 and a base portion 25 a formed on the upper surface of the base 25. A column portion 26 is provided on one end of the upper surface of the base 25, and a head portion 27 is provided on the upper end portion of the column portion 26 in a state of facing the table portion 25 a with a gap.

  Further, a square bar-shaped guide portion 28 whose position can be adjusted in the left-right direction in FIG. 8 is provided on the upper surface of the base portion 25a, and a portion corresponding to the other end side of the base 25 and the head portion 27 in the base portion 25a. Is provided with a stellite blade 29 penetrating through an insertion hole provided in the base portion 25a. This stellite blade 29 is exposed between the base portion 25a and the head portion 27 through the inside of the base 25, the column portion 26, and the head portion 27, and is looped by the operation of a drive portion (not shown). It is driven to rotate. Accordingly, the stellite blade 29 is driven to rotate, and the wooden plate 22 is moved to the stellite blade 29 side along the curved portion 23a along the guide portion 28, whereby the wooden plate 22 is cut and the uprights 16a (16b) are formed. The

  In this case, the distance between the guide portion 28 and the stellite blade 29 is set longer than the set width of the upright 16a (, 16b), for example, 36 mm, by the thickness of the stellite blade 29. Further, when cutting the wooden board 22, the curved portion 23 a of the wooden board 22 is always brought into contact with the portion of the guide portion 28 closest to the stellite blade 29. As a result, the width of the formed upright 16a (, 16b) can be made constant. By repeating this, a plurality of standing bars 16a (16b) are formed.

  Then, when the vertical bars 16a and 16b are formed, the horizontal bars 16c and 16d, the horizontal beam 17a and the vertical beam 17b are also cut to a set length, and the vertical bars 16a and 16b and the horizontal beam constituting the surrounding bone 16 are cut. The core member 18 is formed by sequentially assembling the horizontal braiding member 17a and the vertical braiding member 17b on 16c and 16d. Then, a corner plate 19a and a pulling lever plate 19b are attached to predetermined portions of the core member 18, respectively. At this time, the upright bars 16a and 16b are arranged so that the warping directions are in the same direction. In addition, a fixing tool such as an adhesive or a screw is also used as needed during this assembly.

  Next, a paperboard 21a is attached to the surface of the Japanese-style room on which the curvature of the upright bars 16a and 16b of the core member 18 protrudes, and the paperboard 21b is attached to the surface of the western side of the core material 18 where the curvature of the upright bars 16a and 16b becomes the concave side. Paste. Next, the paper 12 is pasted on the surface of the paperboard 21a, and the decorative sheet 14 is pasted on the surface of the paperboard 21b. The paperboards 21a and 21b, the paper 12 and the decorative sheet 14 are attached to the core member 18 using an adhesive such as glue. Then, the peripheral edge 11 composed of the standing edges 11a and 11b and the horizontal edges 11c and 11d is attached to the outer surface of the core material 18 to which the paperboards 21a and 21b, the paper 12 and the decorative sheet 14 are attached. This attachment is performed using a screw or the like.

  Then, the handle 13 is attached to the portion corresponding to the handle anchor plate 19b in the backing paper 12, and the handle 15 is attached to the portion corresponding to the handle anchor plate 19b in the decorative sheet 14. These pullers 13 and 15 are made of a material appropriately selected from materials such as light alloy, wood, and plastic, and are formed so that the center of the front surface is a recess and the center of the back surface is a protrusion, and the outer periphery of the center portion. A flange-like flange is formed on the part. Further, as described above, a concave portion for pushing in the central portions of the pull handles 13 and 15 is formed at the center of both surfaces of the pull lever anchor plate 19b.

  For this reason, by pushing the center side portions of the pull handles 13 and 15 into the corresponding recesses of the pull catch board 19b, the pull handle 13 breaks through the backing paper 12 and the paper board 21a and is fixed in the pull catch board 19b. The decorative sheet 14 and the paperboard 21b are pierced and fixed in the pulling lever board 19b. At this time, the collar portion of the handle 13 is located on the surface of the liner paper 12, and the collar portion of the handle 15 is located on the surface of the decorative sheet 14.

  Further, since the shrinkage force of the paper 12 is larger than the shrinkage force of the decorative sheet 14, when the adhesive used to paste the paper 12, the decorative sheet 14, and the paperboards 21 a and 21 b is dried, the core material 18 is erected. The protruding surfaces of the crosspieces 16a and 16b are pulled in the direction of contraction by the paper 12. As a result, the curved standing bars 16a and 16b are corrected so as to be in a straight state, and the entire door frame 10 becomes flat as shown in FIGS. This state is maintained while the paperboards 21a, 21b and the like are not peeled from the core material 18.

  As described above, in the door bag 10 according to the present embodiment, the paper 12 having a large shrinkage force is attached to the surface of the core member 18 located on the side of the Japanese-style room, and the decorative sheet 14 having a small shrinkage force is applied to the surface located on the western side. Paste. And the standing bars 16a and 16b are curved and formed so that the surface of the standing bars 16a and 16b of the core member 18 on the side where the paper 12 is stuck is projected. Therefore, when the door cage 10 is assembled, the curved portions of the uprights 16a and 16b are corrected by the shrinkage of the paper 12, and the warp is free. For this reason, for example, when the door 10 is arranged so as to slide along the side of the Japanese room of the wall that divides the Japanese-style room and the Western-style room, the door 10 does not contact the wall, and smooth opening and closing becomes possible.

  Further, in the door bag 10 according to the present embodiment, the paper 12 and the decorative sheet 14 are attached to the core member 18 via the paperboards 21a and 21b subjected to moisture-proof treatment. For this reason, the expansion and contraction of the backing paper 12 and the decorative sheet 14 is reduced, and the curvature of the curve formed on the standing bars 16a and 16b can be reduced. As a result, the adjustment width of the curve formed on the upright bars 16a and 16b is reduced to prevent the warp 10 from warping, so that the curve can be easily formed, and the door 10 with higher flatness can be obtained.

  Furthermore, a paper 12 made of bird's paper is placed on the side of the Japanese-style room of the Toba 10 and a decorative sheet 14 made of a vinyl cloth with a wood grain pattern printed on the side of the Western-style room. The texture according to it can be put out. Further, since the standing bars 16a and 16b are formed by cutting one side 22a of the wooden board 22 in a curved shape using a CNC router and cutting the curved cut surface using a band saw 24, simple operation Thus, the vertical bars 16a and 16b having high dimensional accuracy can be efficiently taken out.

(Second Embodiment)
Moreover, FIG. 9 and FIG. 10 has shown the state which looked at the door rod 30 as a partition door which concerns on 2nd Embodiment of this invention from the back surface side. The door 30 is installed between the Japanese-style room and the closet, and is used to open and close the closet and is used in a pair of two sheets formed symmetrically (only one door 30 is shown). A back paper 34 made of water-resistant high-pressure paper with a pattern on the front surface (outer surface) is attached to the inner portion of the peripheral edge 31 on the back surface (the close-up side) of the door 30. In general, a pattern (not shown) applied to the cloud flower paper is provided on the surface of the back paper 34 by printing.
