Description

  The present invention relates to a unit data structure, a unit design device, a unit design method, a furniture design device and a furniture design system, and a furniture manufacturing support device.

  There is known a furniture design support system for designing furniture using a computer. Patent Document 1 relates to a three-dimensional cell space linked to a three-dimensional cell space that is defined by a frame (basic component) of furniture by associating a three-dimensional part space such as a drawer with a three-dimensional cell space. A system for enlarging or reducing component space is disclosed.

International Patent Publication WO2006 / 064971

  In the system described in Japanese Patent Laid-Open No. 2004-228561, the components that make up the furniture are enlarged or reduced in accordance with the enlargement or reduction of the entire furniture. Therefore, each of the basic components and parts that make up the furniture is individually enlarged or reduced. There is no need to perform an operation, and the design inconvenience can be reduced.

  In the system described in Cited Document 1, furniture is designed by combining basic components and parts registered in advance. Here, some basic components and parts constituting furniture are formed by combining a plurality of plates. For example, the drawer inner box is formed by combining a number of plate materials such as an inner front plate, a left gable plate, a right gable plate, and a bottom plate. In addition, when focusing only on the plate material, a single (innocent) plate material may be used, but a plate material (called plywood) formed by pasting the surface material, the back surface material, the lip material, etc. to the core material. Often used. For example, in the case of designing furniture using drawers that differ only in the thickness of the mouthpiece material affixed to a specific surface of the drawer front plate, the system described in Patent Document 1 uses the end of the desired thickness. Data of drawers using materials must be registered in advance. In the system described in Cited Document 1, in order to respond to all the detailed demands of furniture design, for example, even if focusing only on drawers, data on a very large number of drawers is programmed in advance over a huge amount of time. Must be registered.

  This invention enables not only designing of furniture but also designing of a plurality of types of components (for example, drawers, doors, etc.) constituting the furniture by simply registering simple master data. For the purpose.

  The present invention also makes it possible to easily change the size of one constituent member in accordance with the change in the size of one constituent member while keeping the designed furniture structure. For the purpose.

  The present invention further enables the determination of the dimensions of the minimum members (for example, core material and surface material constituting the plate material) required to manufacture the furniture according to the furniture design. Objective.

  Another object of the present invention is to enable registration of processing information necessary for assembling components according to dimensions of components determined according to furniture design.

  The first invention is not only capable of designing furniture having a structure and shape according to the user's request, but also for various components constituting the furniture, such as frames, drawers, doors, etc. Furniture design that can have the structure and shape according to the user's request, and the material (minimum component member) that constitutes the above-mentioned component member can also have the structure and shape according to the user's request A data structure for realizing the device is provided.

  A first invention is a furniture design apparatus for designing order-made furniture configured by combining one or a plurality of infill units in the frame of the skeleton unit defining the frame of furniture. Provides a data structure for the skeleton unit and infill unit used in.

  In this specification, furniture includes at least a skeleton unit that defines the frame and an infill unit that is combined with the frame of the skeleton unit. Infill units, such as drawer units and shelf units, can be combined in the frame defined by the skeleton unit, depending on the type of infill unit to be combined and the installation position and size of the infill unit. Furniture with a unique shape or structure is designed to be made to order.

  As described above, the skeleton unit and the infill unit perform different functions in configuring furniture, but both are defined with the same data structure. Hereinafter, the skeleton unit and the infill unit are collectively referred to as a “unit”. In the following, “unit” should be understood as a term including both “skeleton unit” and “infill unit”.

  In the first invention, the unit is constituted by one part or by combining a plurality of parts, and the part is constituted by one material or by combining a plurality of materials. Shall be. For example, the drawer inner box unit is configured by combining an inner front plate, a right wife plate, a left wife plate, a bottom plate, a front plate, and the like. Each of the inner front plate, right gable plate, left gable plate, bottom plate, tip plate, etc. is a plurality of parts constituting the drawer inner box unit. Also, for example, the left gable board, which is one of the parts constituting the drawer inner box unit, is, for example, a flat core material, and a surface material and a back material (decorative board ( It is also called decorative laminated sheets))), and can be composed of a plurality of cut end sheets (cut end sheets) that are affixed to the end face (cut end face) of the core material. Each of the core material, the front surface material, the back surface material, and the mouthpiece material is a material constituting the left twill plate part of the drawer inner box unit.

  The data structure of the unit according to the present invention includes the following three tables.

  The first table is defined for each of the one material or the plurality of materials constituting the part, and is a six-dimensional three-dimensional material space (front surface, rear surface, upper surface, It is a material space table that holds material space data that defines each of the surface positions of the lower surface, the left surface, and the right surface) based on a rectangular parallelepiped three-dimensional part space that circumscribes the part to which the material belongs.

  The second table is defined for each of the one part or the plurality of parts constituting the unit, and represents each of the six surface positions of the three-dimensional part space representing a rectangular parallelepiped space circumscribing the part. , A parts space table for holding parts space data defined on the basis of a three-dimensional unit space representing a rectangular parallelepiped space defined for the unit to which the part belongs.

  The third table shows each of the six surface positions of the three-dimensional unit space representing the rectangular parallelepiped space defined for the infill unit as a rectangular parallelepiped space defined in the frame of the skeleton unit. It is a unit space table holding unit space data defined based on a three-dimensional skeleton cell space to be represented. The three-dimensional unit space can be defined as a three-dimensional space that circumscribes the infill unit, or can be defined as a three-dimensional space that is larger or smaller than the infill unit. The first table and the second table are defined for both the skeleton unit and the infill unit, whereas the third table is not defined for the skeleton unit but only for the infill unit. Is done.

  According to the present invention, each of the six surface positions of the rectangular parallelepiped three-dimensional material space circumscribing the material (core material, surface material, etc.) circumscribes the part to which the material belongs (left twill plate, tip plate, etc.). Since it is relatively determined based on the three-dimensional part space, the three-dimensional material space is also enlarged or reduced in accordance with the expansion or reduction of the three-dimensional part space. Since the three-dimensional material space is a space circumscribing the material, the expansion or reduction of the three-dimensional material space means the expansion or reduction of the material.

  Similarly, each of the six surface positions of the three-dimensional part space representing a rectangular space circumscribing a part (left gable plate, tip plate, etc.) is a rectangular parallelepiped space defined for the unit to which the part belongs. Therefore, the three-dimensional part space is also enlarged or reduced according to the expansion or reduction of the three-dimensional unit space. Since the three-dimensional part space is a space circumscribing the part, the enlargement or reduction of the three-dimensional part space means the enlargement or reduction of the part.

  Further, each of the six surface positions of the three-dimensional unit space representing the rectangular parallelepiped space surrounding the unit, which is defined for the unit (the drawer inner box unit, etc.), is the skeleton unit (the cabinet unit, etc.). Since the three-dimensional skeleton cell space representing the rectangular parallelepiped space defined in the frame is defined as a reference, the three-dimensional unit space is expanded or reduced in accordance with the expansion or reduction of the three-dimensional skeleton cell space. The

  The three-dimensional skeleton cell space is enlarged or reduced according to the enlargement or reduction of the skeleton unit. Then, the three-dimensional unit space in which the surface positions of the six planes are determined with reference to the three-dimensional skeleton cell space is automatically enlarged or reduced. Furthermore, the three-dimensional part space in which the surface positions of the six surfaces are determined with reference to the three-dimensional unit space is automatically enlarged or reduced in conjunction with the three-dimensional part space. Furthermore, the three-dimensional material space in which the surface positions of the six surfaces are determined based on the three-dimensional part space is automatically enlarged or reduced in conjunction with the three-dimensional material space. When the 3D skeleton cell space is expanded or reduced, the dimensions of the units, parts and materials incorporated in the skeleton unit that defines the 3D skeleton cell space can be expanded or expanded. Since it is not necessary to separately enlarge or reduce (double enlargement or reduction operation) in accordance with the reduction, the troublesome design is reduced. It is possible to cope with enlargement or reduction in any of six directions (upward, downward, leftward, rightward, near side, and backward).

  When the dimensions of the three-dimensional skeleton cell space are determined, the dimensions of the three-dimensional material space for each of a plurality of materials constituting the furniture are automatically determined. Since the three-dimensional material space is a space circumscribing the material, the dimensions of the material are determined by determining the dimensions of the three-dimensional material space. Process a large number of materials to have the determined dimensions, assemble the parts using the processed materials, assemble the units by combining the assembled parts, and combine the assembled units to actually produce the furniture as designed Can be produced.

  Preferably, each of the six surface positions of the three-dimensional skeleton cell space is defined based on a specific surface of the unit space of the skeleton unit and a specific surface of a plurality of parts constituting the skeleton unit. A cell space table is provided. A three-dimensional skeleton cell space can also be defined as data handled by a computer.

  In one embodiment, when the infill unit has a rectangular parallelepiped inner space surrounded by a plurality of parts, each of the six surface positions of the three-dimensional infill cell space representing the inner space is defined as the infill unit. An infill cell space table may be provided which is determined based on a specific surface of the unit space of the unit and specific surfaces of a plurality of parts constituting the infill unit.

  Each of the surface positions of the six surfaces (front surface, rear surface, upper surface, lower surface, left surface and right surface) of the three-dimensional material space may be directly associated with the three-dimensional part space of the part to which the material belongs. In this case, for example, data indicating that the position of a specific surface (for example, the front surface) of the three-dimensional material space is determined based on the position of the specific surface (for example, the front surface) of the three-dimensional part space is included in the three-dimensional material space data. Stipulated in

  However, at least one of the six surface positions in the three-dimensional material space may be determined based on the position of a specific surface in the three-dimensional material space of another material belonging to the same part. In this case, for example, a specific surface of the three-dimensional material space of one material (for example, the lower surface of the material space of the core material) is pasted on a specific surface of the three-dimensional material space of another material (for example, the lower surface of the core material). Determined based on the position of the upper surface of the material space of the lower mouthpiece material to be obtained. In this case, the thickness of the lower lumber is specified in the three-dimensional material space table for the lower lumber, and the lower surface of the lower lumber is based on the three-dimensional part space of the part to which the lower lumber belongs. By prescribing, the lower surface position of the core material is indirectly determined with reference to the three-dimensional part space.

  For the three-dimensional part space, each of the six surface positions (front, rear, upper, lower, left and right) is determined based on the position of a specific surface in the three-dimensional unit space of the unit to which the part belongs. May be. In this case, the surface positions of the six surfaces of the three-dimensional part space are determined directly on the basis of the three-dimensional unit space. Of course, at least one of the six surface positions in the three-dimensional part space may be determined based on the position of a specific surface in the three-dimensional part space of another part belonging to the same unit. In this case, the surface position of the three-dimensional part space is indirectly determined based on the three-dimensional unit space. The same applies to the three-dimensional unit space.

  In one embodiment, the three-dimensional material space data defines a position of at least one of the six surfaces of the three-dimensional material space by a distance from a corresponding surface of the three-dimensional part space. For the three-dimensional part space data, the position of at least one of the six surfaces of the three-dimensional part space may be defined by the distance from the corresponding surface of the three-dimensional unit space. Further, for the three-dimensional unit space data, the position of at least one of the six surfaces of the three-dimensional unit space may be defined by the distance from the corresponding surface of the three-dimensional cell space. As a result, for example, the front surface of the 3D unit space and the front surface of the 3D part space can be flush with each other, for example, they can be flush with each other. Furniture can be designed.

  In another embodiment, in the 3D material space data, the position of any one of the 6 surfaces of the 3D material space is defined by the distance from the opposite side of the 3D material space. May be. Thereby, the thickness of the material can be defined in the three-dimensional material space data. This means that the surface position of one of the two parallel surfaces that define the thickness of the material is determined by the surface position of the other surface and the thickness of the material. Similarly, in the three-dimensional part space data, the position of any one of the six surfaces of the three-dimensional part space may be defined by the distance from the opposite side of the three-dimensional part space. The thickness of the part is defined. The same applies to the three-dimensional unit space.

  For example, for a specific material, all of the surface positions of the six surfaces of the material space can be defined based on “specific surfaces of the three-dimensional material space of other materials belonging to the same part”.

  An example is introduced. For example, one of the parts, “Plate before drawing” is a flat “core material”, “surface material” and “back material” sandwiching “core material” from both sides, and 4 core materials. It is assumed that it is composed of four end pieces each pasted on one side (end face). In this case, the thickness of the “pre-drawer plate” is the sum of the thickness of the “core material”, the thickness of the “surface material”, and the thickness of the “back material”. For example, in the “surface material” material space table and “back material” material space table, the “distance from the opposite side of the 3D material space” is used to define the thickness of the surface material and back material. On the other hand, in the material space table of “core material”, all of the surface positions of the six surfaces are assigned to other materials belonging to the front plate (for example, the surface material, the back surface material, and the adjacent material adjacent to each of the six surfaces of the core material). It is defined by the distance from the specific surface of the three-dimensional material space of the four lip materials). As a result, even if the thickness of the front and back materials that make up the “pre-drawer plate” is changed, the overall thickness of the “pre-drawer plate” can be kept constant (the thickness of the core is linked). Will be changed). Thus, when the data structure of the present invention is used, for example, the material that defines the thickness of the “pre-drawer plate” without affecting the overall thickness of the “pre-drawer plate” (in the above case, the surface material) It is also possible to change the thickness of the back material). Of course, in the above case, the dimensions remain the same not only for the “drawer plate” (parts) but also for the unit and the entire furniture. The thickness of some materials can be changed without affecting the structure and dimensions of the furniture, the structure and dimensions of the units that make up the furniture, and the dimensions of the parts that make up the units, and others Since the dimensions of the material can be changed in conjunction with each other, it is possible to cope with the detailed demands of furniture design. For example, it is not necessary to previously create data for a large number of units having the same structure with different thicknesses for each material having various thicknesses.

  The second invention provides a unit design apparatus for designing (creating) a unit having the unit data structure described above. The unit design apparatus according to the present invention is used in a furniture design apparatus for designing custom furniture constructed by combining one or a plurality of infill units in the frame of the skeleton unit that defines a frame of furniture. Used for designing data representing the unit, the unit being constituted by one part or a combination of a plurality of parts, and the part being a single material or a combination of a plurality of materials Each of the six surface positions of a three-dimensional material space representing a rectangular parallelepiped space circumscribing the material, which is defined for each of the one material or the plurality of materials constituting the part. Is based on a rectangular parallelepiped three-dimensional part space that circumscribes the part to which the material belongs. Accepts input of material space data, and is defined for each of the one part or a plurality of parts that constitute the unit, and the surface positions of the six surfaces of the three-dimensional part space representing the rectangular space circumscribing the part. Each of the three-dimensional data representing a rectangular parallelepiped space defined for the infill unit is received by receiving part space data input based on a three-dimensional unit space representing the rectangular solid space defined for the unit to which the part belongs. Each of the six surface positions of the unit space accepts unit space data determined based on a three-dimensional skeleton cell space representing a rectangular parallelepiped space defined in the frame of the skeleton unit. In addition, an element for creating a material space table holding the above three-dimensional material space data Spatial table creation means, part space table creation means for creating a part space table for holding the inputted 3D part space data, and unit space for creating a unit space table for holding the inputted 3D unit space data Table preparation means is further provided.

  The second invention also provides a method for designing (creating) data representing the unit.

  Prior to furniture design using the furniture design apparatus, data representing a unit having a desired shape or structure can be designed in the unit design apparatus. Not only can furniture be designed using the furniture design apparatus, but also the shape and structure of a plurality of types of units (for example, drawer inner box units) that constitute the furniture can be freely designed.

  In one embodiment, the unit design apparatus transmits data representing a unit including the unit space table, the one or more parts space tables, and the one or more material space tables as a set. Means. In this case, preferably, the furniture design device receives a set of the unit space table, the parts space table and the material space table transmitted from the unit design device as data representing one unit, and There is provided association means for associating the three-dimensional unit space represented by the data representing the unit received by the receiving means with the three-dimensional skeleton cell space defined in the frame of the skeleton unit. Furniture with units that meet the user's needs can be designed.

  The present invention further relates processing information data required for assembling different parts according to the dimensions of the parts further constituting the unit that constitutes the furniture designed by the furniture design apparatus, to the parts. There is also provided a furniture manufacturing support apparatus provided with processing information registration means for registration. The machining information includes, for example, the number and position of dowel holes that are drilled to join two parts, the hole diameter, the hole depth, the position where the metal fitting should be fixed, and the like.

First. Fig. 1 shows an example of components constituting furniture that is designed by the furniture design system.

  As will be described later, in the furniture design system, furniture is designed by combining a plurality of types of units registered in advance. The units that make up furniture are broadly divided into “skeleton units” and “infill units”.

  “Skeleton unit” is a general term for units constituting a frame, which is the most basic component of furniture structure, and specifically includes a cabinet. The skeleton unit is basically composed of a top plate, a bottom plate, a right side plate, a left side plate, and a back plate, and has a structure with an open front surface.

  As described above, the skeleton unit has an open front surface, and there is a space (inscribed space) surrounded by the open surface and the inner surfaces of the top plate, the bottom plate, the right side plate, the left side plate, and the back plate. As will be described later, the existence of the space that the skeleton unit has can be set (input). In this specification, the space inside the skeleton unit to be set (input) is called “skeleton cell space”. The skeleton cell space is divided into smaller spaces by the infill unit described below. A smaller space formed by division is also referred to as a “skeleton cell space” in this specification. The skeleton cell space is a rectangular parallelepiped three-dimensional space. Details of the skeleton cell space will be described later.

  In addition, a rectangular parallelepiped space inside the skeleton unit is defined as a “skeleton cell space”, and a rectangular parallelepiped space circumscribing the outside of the skeleton unit is also defined. A rectangular space circumscribing the skeleton unit is hereinafter referred to as a “unit space”.

  The “infill unit” is a general term for the components of furniture combined with the skeleton unit described above, and specifically includes a drawer unit, a shelf unit, a door unit, and the like. Similar to the skeleton unit described above, the infill unit basically includes a rectangular parallelepiped three-dimensional space defined by the shape of the infill unit. A rectangular parallelepiped three-dimensional space surrounding the infill unit is also referred to as a “unit space” hereinafter. Although details will be described later, the unit space provided in the infill unit is associated with the skeleton cell space described above. When the skeleton cell space is expanded or contracted by expanding or contracting the skeleton unit, the unit space of the infill unit associated with the skeleton cell space is expanded or contracted accordingly.

  Among the infill units, for example, a drawer unit has a space for storing things inside. Although details will be described later, a rectangular cell space can also be set (input) for the infill unit. In this specification, the cell space inside the infill unit set (input) for the infill unit is referred to as “infill cell space”.

  As described above, the “skeleton unit” is configured by combining a plurality of members including a top plate, a bottom plate, a right side plate, a left side plate, and a back plate. Some “infill units” are configured by combining multiple members such as an inner front plate, a left gable plate, and a right gable plate, such as a drawer inner box unit. Some are composed of two members. One or more members constituting the skeleton unit and the infill unit are referred to as “parts”. As described later, the part defines a rectangular parallelepiped three-dimensional space that circumscribes the part. A rectangular parallelepiped three-dimensional space that circumscribes the parts is hereinafter referred to as a “part space”.

  Some parts are composed of a single member (minimum constituent member), and others are composed by combining a plurality of members. For example, the part “pre-drawer plate” is composed of a core material, a front surface material, a back surface material, and a plurality of wood ends. One or more members constituting the part are referred to as “material”. As described later, a rectangular parallelepiped three-dimensional space circumscribing the material is also defined for the material. A rectangular parallelepiped three-dimensional space circumscribing the material is hereinafter referred to as a “material space”.

2nd. Cell Space and Unit Space FIG. 2 is a perspective view showing an example of the furniture 1. The furniture 1 includes a cabinet unit 2, a door unit 3, and a drawer unit 4. FIG. 2 shows a fixed shelf unit 16 that is automatically provided when the drawer unit 4 is incorporated in the cabinet unit 2, and a hinge k 1 that is automatically provided when the door unit 3 is incorporated in the cabinet unit 2. Each k2 is also indicated by a broken line. First, the above-described “skeleton cell space”, “infill cell space”, and “unit space” will be described using the furniture 1 shown in FIG. 2 as a specific example.

  FIG. 3 shows the relationship between the cabinet unit 2 constituting the furniture 1 shown in FIG. 2 and the skeleton cell space C defined in the cabinet unit 2.

  Since the cabinet unit 2 is one of the skeleton units, as described above, the skeleton cell space C (indicated by a one-dot chain line) that is a rectangular parallelepiped three-dimensional space surrounded by the cabinet unit 2 is set. Can do. A unit space U2 (shown by a two-dot chain line) circumscribing the cabinet unit 2 is also defined in the cabinet unit 2.

  FIG. 4 shows the relationship between the door unit 3 constituting the furniture 1 and the unit space U3 defined in the door unit 3. The door unit 3 is one of infill units, and has a unit space U3 (indicated by a one-dot chain line) which is a rectangular parallelepiped three-dimensional space for the door unit 3.

  FIG. 5 shows the relationship between the drawer unit 4 constituting the furniture 1 and the unit space defined in the drawer unit 4.

  The drawer unit 4 shown in FIG. 5 is configured by combining two units of a pre-drawer plate unit 4A and a drawer inner box unit 4B. Each of the front drawer unit 4A and the drawer inner box unit 4B has a unit space U4A and a unit space U4B (indicated by a one-dot chain line). Although the details will be described later, the front plate unit space U4A and the inner box unit space U4B are associated with each other, thereby defining a unit space for the entire drawer unit 4.

  As shown in FIG. 6, the inner box unit 4B constituting the drawer unit 4 has a space for storing objects, and an infill cell space Cj (indicated by a one-dot chain line) which is a rectangular parallelepiped three-dimensional space. ) Can also be set.

3rd. Part Space As described above, a “part space” is defined for one or more parts constituting the skeleton unit or the infill unit.

5th. Association of Cell Space and Unit Space and Division of Cell Space Referring to FIGS. 13 (A) to 15 (B), the space by the furniture design system along the flow of design (assembly) of furniture 1 shown in FIG. Processing (dividing the skeleton cell space and associating the divided skeleton cell space with the unit space) will be described.

  First, the skeleton unit constituting the basic frame of the furniture to be designed, that is, the cabinet unit 2 is selected here (FIG. 13A). The cabinet unit 2 has the above-described rectangular parallelepiped skeleton cell space C (FIG. 13B).

  Assume that the infill unit to be incorporated into the cabinet unit 2, here the drawer unit 4, is selected and incorporated into the cabinet unit 2 (FIG. 14A). Specifically, an image representing the drawer unit 4 is selected using a display device, an input device (mouse), and the like, and is dragged and dropped into an image representing the cabinet unit 2. When the drawer unit 4 is assembled in the cabinet unit 2, as shown in FIG. 14B, one skeleton cell space C set in the cabinet unit 2 is divided into two regions (two skeleton cell spaces). C1, C2). As described above, the drawer unit 4 includes the pre-drawer plate unit 4A and the drawer inner box unit 4B (see FIG. 5). The unit space U4A of the drawer front plate unit 4A and the unit space U4B of the drawer inner box unit 4B are associated with one of the two divided skeleton cell spaces C1, C2, in this case, the skeleton cell space C2 ( Details of the association will be described later). When the drawer unit 4 is assembled into the cabinet unit 2 with a space above, the fixed shelf unit 16 is automatically incorporated above the drawer inner box unit 4B as described above. The three-dimensional space above the fixed shelf unit 16 becomes the skeleton cell space C1, and the three-dimensional space below the fixed shelf unit 16 becomes the skeleton cell space C2. As will be described later, a gap or dust is set at the top and bottom of the inner box unit 4B, and the unit space U4B of the inner box unit 4B can occupy the entire skeleton cell space C2, while the unit space U4B of the inner box unit 4B. May not occupy the entire skeleton cell space C2 below the fixed shelf unit 16. In such a case, for example, when the unit space U4B of the inner box unit 4B occupies the lower half of the skeleton cell space C2 below the fixed shelf unit 16, the upper part of the skeleton cell space C2 below the fixed shelf unit 16 It is also possible to install shelves, internal drawers, etc. in the half. That is, the skeleton cell space C2 below the fixed shelf unit 16 can be further divided into two. Of course, since the front drawer unit 4A exists in front of the skeleton cell space C2 below the fixed shelf unit 16, the front plate unit and the upper half of the skeleton cell space C2 below the fixed shelf unit 16 It is not possible to install a normal drawer consisting of an inner box unit.

  Since no unit space is associated with the skeleton cell space C1, another infill unit can be incorporated into the skeleton cell space C1.

  FIG. 15 corresponds to FIG. 14B, and shows a case where an infill cell space Cj is set in the drawer inner box unit 4B.

  As described above, a cell space can be set in the infill unit as well as in the skeleton unit. When the drawer inner box unit 4B (see FIG. 6) in which the infill cell space Cj is set is incorporated in the cabinet unit 2, the infill cell space Cj is nested in the skeleton cell space C2. Will be located. In such a case, another infill unit such as a partition unit can be incorporated in the infill cell space Cj.

  Next, referring to FIG. 16A and FIG. 16B, when the door unit 3 is selected and dragged and dropped onto the skeleton cell space C1, the unit space U3 of the door unit 3 becomes the skeleton cell space. Associated with C1. The unit space U3 of the door unit 3 is associated with the front surface of the skeleton cell space C1 of the cabinet unit 2, and the door unit 3 is displayed so as to cover the front surface (front surface) of the cabinet unit 2.

Sixth. Data Structure of Unit Space, Part Space, Material Space, and Cell Space Next, each data structure (data table) of the unit space, part space, material space, and cell space described above will be specifically described.

(1) Pre-drawer plate unit 4A As described above, the pre-drawer plate unit 4A (see FIG. 5) is composed of one part (pre-drawer plate 21), and the pre-drawer plate 21 is composed of a core 21a. , Surface material 21b, back material 21c, upper lip material 21d, lower lip material 21e, left lip material 21f and right lip material 21g (see FIGS. 11 and 12). The pre-drawing plate unit 4A includes a unit space table that defines the unit space of the pre-drawing plate unit 4A, a part space table that defines the part space of the pre-drawing plate 21 that is a part constituting the pre-drawing plate unit 4A, and a pre-drawing unit. It has a material space table that defines the material space of each of the plurality of materials that make up the plate 21.

(I) Material space table of materials constituting the pre-drawer plate unit 21 constituting the pre-drawer plate unit 4A FIG. 17A shows a part space P21 of the pre-drawer plate 21 which is a part constituting the pre-drawer plate unit 4A ( The relationship between the material space M21b (shown by hatching) of the surface material 21b (see FIG. 12), which is one of the materials constituting the pre-drawer plate 21, is illustrated. FIG. 17B shows a material space M21b (shown by hatching) of the surface material 21b, a material space M21d of the upper wooden mouthpiece 21d, a material space M21e of the lower wooden mouthpiece 21e, a material space M21f of the left wooden mouthpiece 21f, and a right wooden mouth. The relationship between the material 21g and the material space M21g (represented by alternate long and short dash lines) is illustrated. FIG. 18 shows a material space table T1 defined for the surface material 21b.

  The material space is a rectangular parallelepiped three-dimensional space that is defined for one or more materials constituting the part and circumscribes the material. In the material space table, the surface-related data with the material space of the part space or other material for each of the six surfaces of the cuboid material space circumscribing the material, that is, the front surface, the rear surface, the upper surface, the lower surface, the left surface, and the right surface. Is stored.

  This will be specifically described with reference to FIGS. 17 (A), 17 (B) and FIG. In the material space table T1 for the surface material 21b constituting the front plate 21 which is a part constituting the front plate unit 4A, the “target surface” for each of the front surface, rear surface, upper surface, lower surface, left surface and right surface, Three types of data “relation type” and “relevant value” are stored.

  Referring to FIG. 18, for example, when focusing on the surface position “front surface”, the target surface is “front surface of parts space”, the related type is “keep a certain distance from the target surface (interlocking)”, and the related value is “0”. It is. Referring to FIG. 17 (A), this is a rectangular parallelepiped part space defined for the front drawer 21 which is the part to which the surface material 21b belongs, in front of the rectangular material space M21b circumscribing the surface material 21b. This indicates that a constant distance is maintained from the front surface of P21 (part space P21 will be described later) and the distance is 0 mm. The position of the front surface of the material space M21b of the surface material 21b, that is, the front surface position of the surface material 21b is determined relatively with reference to the front surface position of the part space P21 of the front plate 21 and the front position and parts of the material space M21b. The front positions of the space P21 coincide. For example, when the part space P21 of the front plate 21 moves in the depth direction, the front surface of the surface material 21b moves in conjunction with this, and the distance between the front surface of the part space P21 of the front plate 21 is 0 mm. Will be kept.

  Referring to FIG. 18, when attention is paid to the surface position “rear surface”, the target surface is “none”, the related type is “keep a certain distance from the opposite surface (non-linked)”, and the related value is “2.5”. It is. Referring to FIG. 17A, this is because the rear surface of the material space M21b of the surface material 21b, that is, the rear surface of the surface material 21b, is constant from the opposite surface, that is, the front surface of the material space M21b of the surface material 21b. This means that the constant distance is 2.5 mm. This indicates that the thickness of the material space M21b of the surface material 21b, that is, the thickness of the surface material 21b is a constant 2.5 mm. It means that the thickness of the surface material M21b is a fixed value of 2.5 mm.

  Referring to FIG. 18, regarding the surface position “upper surface”, the target surface is “the lower surface of the material space of the upper mouthpiece”, the related type is “keep a certain distance from the target surface (interlocking)”, and the related value is “0”. Referring to FIG. 17B, this is because the upper surface of the material space M21b of the surface material 21b, that is, the upper surface of the surface material 21 is the material of the upper end material 21d, which is another material constituting the same leading plate 21. This indicates that a certain distance is maintained from the lower surface of the space M21d and the distance is 0 mm. The upper surface position of the material space M21b of the surface material 21b, that is, the upper surface position of the surface material 21b is relatively determined with reference to the lower surface position of the material space M21d of the upper mouthpiece material 21d, and the lower surface of the material space M21d of the upper mouthpiece material 21d. Matches. It means that the upper surface position of the surface material 21b is determined by determining the lower surface position of the upper end member 21d.

  Referring to FIG. 18, the surface positions “lower surface”, “left surface”, and “right surface” are determined in the same manner as the above-described surface position “upper surface”. Referring also to FIG. 17B, the lower surface position of the surface material 21 b is determined by determining the upper surface position of the lower end material 21. The left surface position of the surface material 21b is determined by determining the right surface position of the left mouthpiece material 21f. The position of the right surface of the surface material 21b is determined by determining the position of the left surface of the right mouthpiece material 21g.

  FIG. 19 illustrates the relationship between the part space P21 (shown by a one-dot chain line) of the pre-drawer plate 21 and the material space M21e (shown by hatching) of the lower end material 21e constituting the pre-drawer plate 21. FIG. 20 shows the material space table T2 defined for the lower end piece 21e.

  Referring to FIG. 20, for example, when focusing on the surface position “front surface”, the target surface is “front surface of the part space”, the related type is “keep a certain distance from the target surface (interlocking)”, and the related value is “0”. It is. Referring to FIG. 19, this means that the front position of the material space M21e of the lower wooden mouthpiece 21e is kept at a constant distance from the front of the part space P21 of the drawer front plate 21 to which the lower wooden mouthpiece 21e belongs, and the distance is 0 mm. It represents that. The front position of the material space M21e of the lower wooden mouthpiece 21e is relatively determined with reference to the front position of the part space P21 of the drawer front plate 21, and always matches the front position of the part space P21. That is, by determining the front position of the part space P21 of the drawer front plate 21, the front position of the material space M21b of the lower wooden mouthpiece 21b, that is, the front position of the lower wooden mouthpiece 21e is determined. Similarly, the positions of the rear surface, the lower surface, the left surface and the right surface of the material space M21e of the lower wooden mouthpiece 21b are the positions of the corresponding surfaces in the part space P21 of the drawer front plate 21, that is, the rear surface, the lower surface, the left surface and the right surface of the part space P21. Match each position. Only the upper surface position of the material space M21e of the lower end material 21e is defined by the distance from the opposite surface, that is, the lower surface (= 0.5 mm). This indicates that the thickness of the lower end piece 21e is fixed to 0.5 mm.

  FIG. 21A shows a material space M21a (shown by hatching) of the core material 21a (see FIGS. 11 and 12) that constitutes the drawer front plate 21, a material space M21d of the upper lip material 21d, and a material of the lower lip material 21e. The relationship between the space M21e, the material space M21f of the left mouthpiece 21f, and the material space M21g (shown by a one-dot chain line) of the right mouthpiece 21g is illustrated. FIG. 21B shows the relationship between the material space M21a (indicated by hatching) of the core material 21a, and the material space M21b of the front surface material 21b and the material space M21c (indicated by a dashed line) of the back surface material 21c. FIG. 22 shows a material space table T3 defined for the core material 21a.

  The surface positions of the six surfaces of the material space M21a of the core material 21a are all determined relative to the position of a specific surface of the material space of the other material constituting the leading plate 21 to which the core material 21a belongs. ing. Referring to FIG. 21B and FIG. 22, for example, the front surface position of the material space M21a of the core material 21a is the material space of the surface material 21b which is another material constituting the drawer front plate 21 to which the core material 21a belongs. A constant distance is maintained from the rear surface position of M21b, and the fixed distance is set to 0 mm. That is, the front surface position of the core material 21a is relatively determined according to the rear surface position of the surface material 21b, and the front surface of the core material 21a is in contact with the rear surface of the surface material 21b. Referring to FIG. 21A and FIG. 22, the upper surface position of the material space M21a of the core material 21a is the material space M21d of the upper lip material 21d, which is another material that constitutes the drawer front plate 21 to which the core material 21a belongs. A certain distance from the lower surface of the plate is maintained, and the distance is set to 0 mm. The upper surface position of the core material 21a is relatively determined based on the lower surface position of the upper mouthpiece material 21d, and the upper surface of the core material 21 is in contact with the lower surface of the upper mouthpiece material 21d.

  The description of the material space table of the other materials constituting the front drawer plate 21, that is, the back material 21c, the upper wood material 21d, the left wood material 21f, and the right wood material 21g is omitted. In the material space table, the surface position of the surface is the surface position of the specific surface of the part space of the part to which the material belongs, the distance from the opposite side of the material space, and the material space of other material belonging to the same part. It is determined relative to one of the surface positions of the surface.

  As described above, the surface positions of the six surfaces of the material space M21a of the core material 21a are all determined based on the surface positions of specific surfaces of the material spaces of other materials (see FIG. 22). Indirectly, it is also associated with the part space P21. For example, referring to FIG. 22, the position of the lower surface of material space M21a of core material 21a is determined with reference to the upper surface of material space M21e of lower end material 21e. Referring now to FIG. 20, the upper surface position of the material space M21e of the lower wooden mouthpiece 21e is determined based on the lower surface (opposite surface) of the raw material space M21e of the lower wooden mouthpiece 21e, and further the raw material space of the lower wooden mouthpiece 21a. The position of the lower surface of M21e is determined based on the lower surface of the part space P21. That is, it can be seen that the lower surface position of the material space M21a of the core material 21a is indirectly determined with reference to the lower surface of the part space P21 of the pre-drawer plate 21 to which the core material 21a belongs.

  The material space table defined for a plurality of materials constituting the pre-drawer plate 21 has been explained by taking the pre-drawer plate 21 as a part constituting the pre-drawer plate unit 4A as an example, but the parts constituting other units Similarly, a material space table is provided for each material.

(Ii) Parts space table of the pre-drawing plate 21 constituting the pre-drawing plate unit 4A Next, the parts space table will be described in detail. FIG. 23 illustrates the relationship between the unit space U4A of the pre-drawing plate unit 4A and the part space P21 of the pre-drawing plate 21 which is a part constituting the pre-drawing plate unit 4A. In FIG. 23, a rectangular parallelepiped portion indicated by hatching is a parts space P21 of the drawer front plate 21. A rectangular parallelepiped portion surrounded by an alternate long and short dash line is a unit space U4A of the drawer front plate unit 4A. FIG. 24 shows a part space table T4 defined for the pre-drawer plate 21. FIG.

  The part space is a rectangular parallelepiped three-dimensional space that is defined for one or a plurality of parts constituting the unit. The part space table defines data related to the unit space for each of the six surfaces of the rectangular parallelepiped part space that circumscribes the parts, that is, the front surface, the rear surface, the upper surface, the lower surface, the left surface, and the right surface.

  Since the pre-drawing plate unit 4A has only the pre-drawing plate 21 as a part, only the parts space table T4 of the pre-drawing plate 21 is defined for the pre-drawing plate unit 4A.

  Referring to FIG. 24, the parts space table T4 of the front plate 21 has a “target surface”, “relation type” and “relevant value” for each of the front surface, rear surface, upper surface, lower surface, left surface and right surface. Three pieces of data are stored.

  For example, focusing on the surface position “front”, the target surface is “front of the unit space”, the related type is “keep a certain distance from the target surface (interlocking)”, and the related value is “0”. Referring to FIG. 23, this means that the front position of the rectangular parallelepiped part space P21 circumscribing the front plate 21 is a unit space U4A (unit space) defined for the front plate unit 4A to which the front plate 21 belongs. U4A is kept at a certain distance from the front surface (to be described later), and the certain distance is 0 mm. It represents that the front position of the part space P21 and the front position of the unit space U4A coincide. The front position of the part space P21 of the pre-drawing plate 21, that is, the front position of the pre-drawing plate 21, is relatively determined based on the front position of the unit space U4A of the pre-drawing plate unit 4A. For example, when the unit space U4A of the front plate unit 4A moves in the depth direction, the front surface of the front plate 21 moves in conjunction with this, and the distance between the front surface of the unit space U4A of the front plate unit 4A. Is kept at 0 mm.

  Referring to FIG. 24, when attention is next focused on the surface position “rear surface”, the target surface is “rear surface of unit space”, the related type is “keep a certain distance from the target surface (interlocking)”, and the related value is “ -3 ". Referring to FIG. 23, this means that the rear surface position of the part space P21 of the front plate 21, that is, the rear surface position of the front plate 21 is 3 mm inside (ie, the front) of the rear surface of the unit space U4A of the front plate unit 4A. ). The rear surface position of the drawer front plate 21 is determined by determining the rear surface position of the drawer front plate unit 4A, and is 3 mm between the rear surface of the drawer front plate 21 and the rear surface of the unit space U4A of the drawer front plate unit 4A. Spaced.

  Referring to FIG. 24, when attention is next focused on the surface position “upper surface”, the target surface is “upper surface of unit space”, the related type is “keep a certain distance from the target surface (interlocking)”, and the related value is “ -2 ". Referring to FIG. 23, this means that the upper surface position of the part space P21 of the pre-drawer plate 21, that is, the upper surface position of the pre-drawer plate 21, is inward by 2 mm from the upper surface of the unit space U4A of the pre-drawer plate unit 4A (that is ). The upper surface position of the pre-drawer plate 21 is determined by determining the upper surface position of the unit space U4A of the pre-drawer plate unit 4A, and between the upper surface of the pre-drawer plate 21 and the upper surface of the unit space U4A of the pre-drawer plate unit 4A. Are spaced 2 mm apart.

  Similarly, the surface positions “lower surface”, “left surface”, and “right surface” are determined by determining the positions of the lower surface, the left surface, and the right surface of the unit space U4A of the front drawer unit 4A.

  Referring to FIG. 24, by not setting the related value to “0” in the part space table T4, an interval can be provided between the part space and the unit space. This is not a slight gap between one member and another member constituting the furniture, or the specific surface of one member and the specific surface of the other member are not flush with each other. This is called “Chile”).

(Iii) Unit space table of the drawer front plate unit 4A Next, the unit space table will be described in detail. FIG. 25A shows a skeleton cell space C2 (see FIG. 14B), a unit space U4A (shown by an alternate long and short dash line) of the drawer front plate unit 4A, and a part space P21 of the aforementioned drawer front plate 21 ( The relationship with the bottom plate 12, the back plate 15 and the fixed shelf unit 16 (shown by a thick solid line) constituting the cabinet unit 2 is illustrated in a cross section. FIG. 25 (B) shows the relationship between the unit space U4A (indicated by the alternate long and short dash line) of the pre-drawer plate unit 4A and the part space P21 (indicated by the solid line) of the pre-drawer plate 21 as the bottom plate constituting the cabinet unit 2. 12, the left side plate 13, the right side plate 14, and the fixed shelf unit 16 (shown by a thick solid line) are illustrated from the front.

  Here, FIG. 25A and FIG. 25B show a “pre-drawer plate unit 4A (pre-drawer plate 21)” of the “full cover” type. "Full cover" means that the drawer front plate unit 4A (drawer front plate 21) is a member of the cabinet unit 2, in FIGS. 25 (A) and 25 (B), the left side plate 13, the right side plate 14, the bottom plate 12, and This means that the fixed shelf unit 16 has a size (dimension) that covers almost the entire surface. On the other hand, if the pre-drawer plate unit 4A (pre-drawer plate 21) has a size (dimension) covering almost half of the left side plate 13, the right side plate 14, the bottom plate 12, and the fixed shelf unit 16, Called the “cover” type. FIG. 26 shows a “half cover” type pre-drawing plate unit 4A (pre-drawing plate 21). Whether the front drawer unit 4A (drawer front board 21) is of the “full cover” type or “half cover” type is automatically determined by the furniture design system depending on the presence and type of top, bottom, left and right infill units. Selected.

  FIG. 27 shows a unit space table T5 defined for the pre-drawer plate unit 4A.

  The unit space is a rectangular parallelepiped three-dimensional space defined for the unit as described above. Unlike the material space and parts space described above, the unit space is not necessarily a space circumscribing the unit. The unit space may be a three-dimensional space that defines a range larger than the unit, or may be a three-dimensional space that defines a range smaller than the unit. Here, a unit space that divides a range larger than the unit will be described. As shown in FIG. 27, the unit space table T5 includes surface-related data with respect to the skeleton cell space on each of the six surfaces of the rectangular parallelepiped unit space, that is, the front surface, the rear surface, the upper surface, the lower surface, the left surface, and the right surface. It is prescribed.

  A specific description will be given with reference to FIGS. Referring to FIG. 27, the unit space table T5 of the front drawer unit 4A includes “target surface”, “relation type”, and “relevant value” for each of the front surface, rear surface, upper surface, lower surface, left surface, and right surface. Are stored.

  For example, focusing on the surface position “front”, the target surface is “none”, the related type is “keep a certain distance from the opposite surface (non-interlocking)”, and the related value is “23”. Referring to FIG. 25 (A), this means that the front position of the unit space U4A (dashed line) of the front drawer unit 4A is kept at a certain distance from the opposite surface, that is, the rear surface position of the unit space U4A. This indicates that the constant distance is 23 mm. That is, the front surface position of the unit space U4A of the front drawer unit 4A is relatively determined with reference to the rear surface position of the unit space U4A. When the rear surface position of the unit space U4A of the pre-drawing plate unit 4A is determined, the front surface position of the pre-drawing plate unit 4A (pre-drawing plate 21) is determined. The related value “23” is a clearance between the rear surface of the part space P21 of the front plate 21 and the rear surface of the unit space U4A of the front plate unit 4A (see FIG. 23 and FIG. 24) is the total value of 3 mm.

  Referring to FIG. 27, when attention is next focused on the surface position “rear surface”, the target surface is “front surface of skeleton cell space”, the related type is “keep a certain distance from the target surface (interlocking)”, and the related value. Is “0”. Referring to FIG. 25 (A), this is because the rear surface of unit space U4A of drawer front plate unit 4A is a fixed distance from the front surface position of skeleton cell space (skeleton cell space C2 in FIG. 25 (A)). And the constant distance is 0 mm.

  Here, the rear surface of the drawer front plate 21 which is a part constituting the drawer front plate unit 4A is positioned so as to be located inside (front) by 3 mm from the rear surface of the unit space U4A of the drawer front plate unit 4A. Data is stored in the part space table T4 (see FIGS. 23 and 24). Therefore, a gap of 3 mm is provided between the cabinet unit 2 and the pre-drawing plate unit 4A (pre-drawing plate 21) (see FIG. 25A). This 3 mm gap is provided between the front plate unit 4A (drawer plate 21) and the cabinet unit 2 as a cushioning material (when the drawer unit 4 is stored in the cabinet unit 2, the rear surface of the front plate unit 4A ( It can be used to provide a cushion) for preventing the back surface from contacting the cabinet unit 2 directly.

  Returning to FIG. 27, focusing on the surface position “upper surface”, the target surface is “upper surface of the skeleton cell space” and the related type is “keep a certain distance from the target surface (interlocking)”. , The related value is “20 (full cover)” or “10 (half cover)”. Referring to FIGS. 25 (A), 25 (B), and 26, this means that the upper surface position of the unit space U4A of the pre-drawer plate unit 4A is when the pre-drawer plate unit 4A is completely covered (FIG. 25 ( If (A) and (B)), the skeleton cell space C2 is positioned 20 mm outward (ie, upward) from the upper surface, and if the front drawer unit 4A is half covered (FIG. 26), the skeleton cell It means that the position is 10 mm outward (ie, upward) from the upper surface of the space C2. This is based on the premise that the plate thickness of the fixed shelf unit 16 above the skeleton cell space C2 is 20 mm. The upper surface of the unit space U4A of the front drawer unit 4A coincides with the upper surface of the fixed shelf unit 16 in the case of full cover, and passes through the center of the width connecting the vertical direction of the fixed shelf unit 16 in the case of half cover. Matches.

  The surface positions of the “lower surface”, “left surface”, and “right surface” of the unit space U4A of the front plate unit 4A are defined in the same manner as the “upper surface”.

  Parts space table so that the upper surface of the front drawer plate 21 which is a part constituting the front drawer unit 4A is located 2 mm inside (lower) from the upper surface of the unit space U4A of the front drawer unit 4A. Data is stored in T4 (see FIGS. 23 and 24). For this reason, the upper surface of the drawer front plate unit 4A (the drawer front plate 21) is a horizontal plane (half-covered) passing through the upper surface of the fixed shelf unit 16 (when fully covered) or the center of the width connecting the vertical direction of the fixed shelf unit 16. 2mm below the case). Thereby, for example, even if the two drawer units 4 are provided so as to be adjacent to each other in the vertical direction, a slight gap is generated between the pre-drawer plate units 4A (pre-drawer plates 21). It is possible to prevent rubbing between the front drawer unit 4A adjacent vertically.

  Thus, the drawer front plate unit 4A includes a unit space table T5 (FIG. 27), a parts space table T4 (FIG. 24), and material space tables T1 to T3 of a plurality of materials (FIGS. 18, 20 and 20). FIG. 22) is defined.

  For example, the thickness of the lower end piece 21e attached to the lower surface of the drawer front plate unit 4A (drawer plate 21) (see FIGS. 11 and 12) is increased or decreased (such furniture is designed or modified). ). In this case, referring to FIG. 20, the related value (0.5) for the upper surface of the lower end piece 21e representing the thickness of the lower end piece 21e is increased or decreased. Here, referring to FIG. 18, the lower surface position of the surface material 21a adjacent to the lower mouthpiece 21e is determined with reference to the upper surface of the material space M21e of the lower mouthpiece 21e. When the thickness (the position of the upper surface) is changed, the dimension of the surface material 21a is also changed in conjunction with this. In this way, it is possible to modify the dimensions of the material, which is the smallest unit member constituting the furniture, and the dimensions of the other materials are modified in conjunction with the modification. Even small specification changes can be dealt with quickly.

  Another example will be described. For example, it is assumed that the thickness of the surface material 21b of the pre-drawing plate unit 4A (pre-drawing plate 21) is increased or decreased. Referring to FIG. 18, the related value (2.5) for the rear surface of surface material 21b representing the thickness of surface material 21b is increased or decreased. Here, referring to FIG. 22, since the front position of the core material 21a adjacent to the surface material 21b is determined with reference to the rear surface of the material space M21b of the surface material 21b, the thickness of the surface material 21b ( When the position of the rear surface is changed, the dimensions of the core material 21a are also changed in conjunction with this. That is, it means that the change in the thickness of the surface material 21b is absorbed by the change in the thickness of the core material 21a associated therewith. In this way, it is possible to change the thickness of the surface material 21b that defines the thickness of the pre-drawer plate 21 without changing the dimension (thickness) of the pre-drawer plate 21.

(2) Drawer inner box unit 4B Next, with respect to the drawer inner box unit 4B (see FIG. 5) composed of a plurality of parts, the data structures (data tables) of the unit space, parts space, and material space are specified. I will explain it.

  As described above, the drawer inner box unit 4B is composed of seven parts: the bottom plate 22, the left gable plate 23, the right gable plate 24, the front plate 25, the inner front plate 26, the left rail 27, and the right rail 28. Each has a parts space (Fig. 8). Furthermore, when a part is composed of a plurality of materials, each material has a material space.

  As an example, the left wife plate 23 of the drawer inner box unit 4B is taken up. 28A and 28B show a unit space U4B (one-dot chain line) of the drawer inner box unit 4B, a parts space P23 (hatching) of the left gable plate 23 constituting the drawer inner box unit 4B, and the left gable plate 23. The relationship of the material space M23 (thick solid line) of the surface material that constitutes the surface (outer surface) is illustrated.

(I) Material space of the surface material constituting the left gable plate 23 constituting the drawer inner box unit 4B FIG. 29 shows a material space table T6 defined for the surface material of the left gable plate 23 of the drawer inner box unit 4B. .

  Referring to FIG. 29, the material space table T6 for the surface material constituting the left gable plate 23 constituting the drawer inner box unit 4B includes “target surface” for each of the front surface, rear surface, upper surface, lower surface, left surface and right surface. "," Relation type "and" Relation value "are stored.

  For example, focusing on the surface position “front”, the target surface is “front of the part space”, the related type is “keep a certain distance from the target surface (interlocking)”, and the related value is “0”. Referring to FIGS. 28 (A) and 28 (B), this is the front surface of a rectangular parallelepiped material space M23 (thick solid line in FIGS. 28 (A) and 28 (B)) circumscribing the surface material constituting the left gable plate 23. The position indicates that a certain distance is maintained from the front surface position of the rectangular parallelepiped part space P23 (hatching) defined for the left gable plate 23 to which the surface material belongs, and the distance is 0 mm. The front surface position of the material space M23 of the surface material is relatively determined based on the front surface position of the part space P23 of the left gable plate 23. The surface positions “rear surface”, “lower surface” and “left surface” of the material space M23 of the surface material are similarly determined based on the rear surface, the lower surface and the left surface of the part space P23 of the left gable plate 23. .

  Focusing on the surface position “upper surface”, the target surface is “the lower surface of the upper end material space”, the related type is “keep a certain distance from the target surface (interlocking)”, and the related value is “0”. This means that the rear surface position of the material space M23 of the surface material keeps a certain distance from the lower surface position of the material space of the upper end material, which is another material constituting the same left gable plate 23, and the distance is 0 mm. Represents. That is, the upper surface position of the surface material is determined by the upper surface of the surface material interlocking with the lower surface of the upper mouthpiece material and determining the lower surface position of the upper mouthpiece material.

  For the surface position “right surface”, the target surface is “none”, the relationship type is “keep a certain distance from the opposite surface (not linked)”, and the relationship value is “2.5”. This indicates that the thickness of the surface material is 2.5 mm.

  A material space table is also provided for each of the other materials constituting the left gable plate 23, that is, the back surface material and the plurality of wood ends.

(Ii) Parts space of the left gable plate 23 constituting the drawer inner box unit 4B FIG. 30 shows a parts space table T7 defining the part space P23 of the left gable plate 23 constituting the drawer inner box unit 4B.

  Referring to FIG. 30, the front, rear, upper, lower, left and right sides of the part space table T7 of the left gable plate 23 which is one of a plurality of parts constituting the drawer inner box unit 4B are also “ Three pieces of data of “target surface”, “relation type” and “relevant value” are stored.

  For example, focusing on the surface position “front”, the target surface is “front of the unit space”, the related type is “keep a certain distance from the target surface (interlocking)”, and the related value is “0”. Referring to FIGS. 28 (A) and 28 (B), this means that the front position of the rectangular parallelepiped part space P23 (hatching) circumscribing the left gable plate 23 is the drawer inner box unit 4B to which the left gable plate 23 belongs. This means that a constant distance is maintained from the front surface position of the unit space U4B (dashed line) defined by, and the constant distance is 0 mm. The front position of the part space P23 of the left gable plate 23, that is, the front position of the left gable plate 23 is relatively determined with reference to the front position of the unit space U4B of the drawer inner box unit 4B.

  Returning to FIG. 30, focusing on the surface position “upper surface”, the target surface is “upper surface of unit space”, the related type is “keep a certain distance from the target surface (interlocking)”, and the related value is “−5”. It is. Referring to FIG. 28 (A), this is because the upper surface position of the rectangular parallelepiped part space P23 circumscribing the left wife plate 23 is from the upper surface of the unit space U4B defined for the drawer inner box unit 4B to which the left wife plate 23 belongs. It means that the position is inside (ie, below) by 5 mm. The upper surface position of the left gable plate 23 is determined by determining the upper surface position of the unit space U4B of the drawer inner box unit 4B.

  Focusing on the surface position “left surface”, the target surface is “left surface of unit space”, the related type is “keep a certain distance from the target surface (interlocking)”, and the related value is “−13”. Referring to FIG. 28 (A), this indicates that the left surface position of the rectangular parallelepiped part space P23 circumscribing the left wife plate 23 is the left surface position of the unit space U4B defined for the drawer inner box unit 4B to which the left wife plate 23 belongs. It means that the position is 13 mm from the inside (ie, the right side). This means that a left rail 27 is provided on the left surface (outer surface) of the left gable plate 23 (see FIG. 8), and the left surface position of the left gable plate 23 is determined in consideration of the thickness of the left rail 27. . In any case, the left surface position of the left gable plate 23 is determined based on the left surface position of the unit space U4B of the drawer inner box unit 4B.

  Focusing on the surface position “right surface”, the target surface is “none”, the relationship type is “keep a certain distance from the opposite surface (non-interlocking)”, and the relationship value is “15”. It represents that the thickness of the left gable plate 23 is a fixed value of 15 mm.

  The above-described parts space table is defined not only for the left gable plate 23 but also for other parts (see FIG. 8) constituting the drawer inner box unit 4B.

(Iii) Unit Space of Drawer Inner Box Unit 4B FIG. 31 shows a unit space U4B (shown by an alternate long and short dash line) of the drawer inner box unit 4B, a skeleton cell space C2, and a unit space U4A of the aforementioned drawer front plate unit 4A. (Represented by a two-dot chain line), parts space P21 of the front plate 21 (shown by hatching), the bottom plate 12, the back plate 15 and the fixed shelf unit 16 constituting the cabinet unit 2 (shown by a thick solid line) In addition, it is shown in cross section. FIG. 32 shows a unit space table T8 of the drawer inner box unit 4B.

  Referring to FIG. 32, when attention is paid to the surface position “front surface” in the unit space table T8 of the drawer inner box unit 4B, the target surface is “the rear surface of the unit space of the drawer front plate” and the related type is “from the target surface”. Keep a certain distance (interlocking) "and the related value is" -3 ". Referring to FIG. 31, this is because the front position of unit space U4B (one-dot chain line) of drawer inner box unit 4B is 3 mm inside (frontward) from the rear surface of unit space U4A (two-dot chain line) of drawer front plate unit 4A. ) Position. The front surface position of the unit space U4B of the drawer inner box unit 4B is located 3 mm inside from the rear surface of the unit space U4A of the front drawer unit 4A. This means that the rear surface position of the pre-drawer plate unit 4A (pre-drawer plate 21) and the front surface position of the unit space U4B of the drawer inner box unit 4B are the same position. The front surface position of the unit space U4B of the drawer inner box unit 4B is determined with reference to the rear surface position of the front plate unit space U4A, and is not directly related to the front surface of the skeleton cell space C2. However, the rear surface position of the unit space U4A of the drawer front plate unit 4A is determined based on the front surface of the skeleton cell space C2 (see FIG. 27), and therefore the front surface position of the unit space U4B of the drawer inner box unit 4B is Indirectly, it is determined based on the front surface of the skeleton cell space C2.

  Returning to FIG. 32, regarding the surface position “rear surface”, the target surface is “rear surface of the skeleton cell space”, the related type is “keep a certain distance from the target surface (interlocking)”, and the related value is “−5”. It is. Referring to FIG. 31, this means that the rear surface position of the unit space U4B of the drawer inner box unit 4B is kept at a certain distance inward from the rear surface position of the skeleton cell space C2 (the inner surface position of the back plate 15). The constant distance is 5 mm. When the drawer inner box unit 4B is placed in the skeleton cell space C2, a gap of 5 mm is secured between the drawer inner box unit 4B and the back plate 15.

  Focusing on the surface position “upper surface”, the target surface is “upper surface of the skeleton cell space”, the related type is “keep a certain distance from the target surface (interlocking)”, and the related value is “0”. Referring to FIG. 31, this means that the upper surface position of unit space U4B of drawer inner box unit 4B is the same position as the upper surface position of cell space C2 (that is, the lower surface position of fixed shelf unit 16). . When the upper surface position of the skeleton cell space C2 is determined, the upper surface position of the unit space U4B of the drawer inner box unit 4B is determined.

  Here, as described above, there is a gap of 5 mm between the unit space U4B of the drawer inner box unit 4B and the upper surface of the left gable plate 23 constituting the drawer inner box unit 4B (see FIG. 28A). . Thereby, when the drawer inner box unit 4B is put into the skeleton cell space C2, the left gable plate 23 constituting the drawer inner box unit 4B does not come into contact with the fixed shelf unit 16.

  When the size of the skeleton cell space defined in the skeleton unit is determined, the size of the unit space for the infill unit incorporated in the skeleton cell space is determined. When the dimensions of the unit space are determined, the dimensions of a plurality of parts constituting the infill unit are determined. When the dimensions of a part are determined, the dimensions of a plurality of materials constituting the part are determined. In other words, the size of each of the plurality of materials is determined to determine whether the designed furniture can be manufactured.

  Also for the door unit 3 (FIG. 4) described above, since the unit space U3 of the door unit 3 is associated with the skeleton cell space C1 (FIG. 16B), the door unit 3 is determined when the dimensions of the skeleton cell space C1 are determined. When the dimensions of the unit space U3 are determined and the dimensions of the unit space U3 of the door unit 3 are determined, the dimensions of the parts and materials constituting the door unit 3 are determined.

(3) Skeleton Cell Space FIG. 33 shows the cell space table T9 of the skeleton cell space C (FIGS. 13A and 13B) defined in the cabinet unit 2. 34 and 35 show a cell space table T10 for the skeleton cell space C1 and a cell space for the skeleton cell space C2 when the skeleton cell space C is divided into two skeleton cell spaces C1 and C2. Table T11 is shown respectively.

  As described above, the cabinet unit 2 includes the top plate 11, the bottom plate 12, the left side plate 13, the left side plate 14, and the back plate 15, and has a structure in which the front surface is open (see FIG. 7). The cabinet unit 2 has a rectangular parallelepiped unit space U2 circumscribing the cabinet unit 2 and a skeleton cell space C that defines an inner space partitioned by the cabinet unit 2 (FIG. 3).

  Referring to FIG. 33, a cell space table T9 shown in FIG. 33 defines an inner skeleton cell space C partitioned by the cabinet unit 2. The cell space table T9 also stores three data of “target surface”, “related type”, and “related value” for each of the front surface, rear surface, upper surface, lower surface, left surface, and right surface.

  Focusing on the surface position “front surface”, the target surface is “front surface of the unit space of the cabinet unit”, the related type is “keep a certain distance from the target surface (interlocking)”, and the related value is “0”. Referring to FIG. 3, this means that the front surface (that is, the opening surface) of the skeleton cell space C defined for the cabinet unit 2 has a certain distance from the front surface of the unit space U 2 defined for the cabinet unit 2. This means that the distance is 0 mm. The front surface of the skeleton cell space C coincides with the front surface of the unit space U2 of the cabinet unit 2. The unit space U2 of the cabinet unit 2 is also defined by the unit space table, but the six surfaces of the unit space U2 of the cabinet unit 2 are basically not related to other unit spaces or cell spaces, and are designed for furniture. The position is determined by the operation (numerical numerical input) of the apparatus.

  With reference to the surface position “rear surface”, the target surface is “the front surface of the part space of the back plate”, the related type is “keep a certain distance from the target surface (interlocking)”, and the related value is “0”. This means that the rear surface of the skeleton cell space C of the cabinet unit 2 coincides with the front surface of the part space of the back plate 15.

  As for the surface positions “upper surface”, “lower surface”, “left surface”, and “right surface”, similarly to the surface position “rear surface”, the “top plate”, “base plate”, “left side plate” and Their positions are determined with reference to a specific plane in the part space of the “right side plate”.

  As described above, when the drawer unit 4 is incorporated in the cabinet unit 2, the skeleton cell space C is divided into two skeleton cell spaces C1 and C2 (see FIGS. 14A and 14B). Instead of the cell space table T9 defined for the skeleton cell space C, cell space tables T10 and T11 for defining the two skeleton cell spaces C1 and C2 (FIGS. 34A and 34B). ) Is newly defined.

  Referring to FIGS. 34 (A) and 14 (B), cell surface table T10 for skeleton cell space C1 indicates that the target surface for surface position “lower surface” is “upper surface of unit space of fixed shelf unit”. This is different from the cell space table T9 for the skeleton cell space C shown in FIG. The position of the lower surface of the divided skeleton cell space C1 is determined based on the upper surface of the unit space of the fixed shelf unit 16 (see FIG. 2).

  Referring to FIG. 34B and FIG. 14B, in the cell space table T11 for the skeleton cell space C2, the target surface for the surface position “upper surface” is “the lower surface of the fixed shelf unit space”. This is different from the cell space table T9 for the skeleton cell space C shown in FIG. The position of the upper surface of the divided skeleton cell space C2 is determined based on the lower surface of the unit space of the fixed shelf unit 16 (see FIG. 2).

(4) Infill Cell Space FIG. 35 shows a cell space table T12 defined for the infill cell space Cj (see FIG. 15) set in the drawer inner box unit 4B. As described above, when a space for storing, for example, an object exists in the infill unit, an infill cell space can be set for the space.

  Referring to FIG. 35, in the cell space table T12 that defines the infill cell space Cj set in the drawer inner box unit 4B, the surface positions of the front surface, rear surface, upper surface, lower surface, left surface, and right surface are in the drawer. It is determined on the basis of the specific surfaces of the parts constituting the box unit 4B and the unit space U4B (see FIG. 5) defined for the drawer inner box unit 4B. For example, for the surface position “front”, the target surface is “the rear surface of the part space of the inner front plate”, and the related type is “keep a certain distance from the target surface (interlocking)”. The position of the front surface of the infill cell space Cj set for the drawer inner box unit 4B is determined with reference to the rear surface of the part space P26 (see FIG. 8) of the inner front plate 26. The surface position “upper surface” is determined with reference to the upper surface of the unit space U4B defined for the drawer inner box unit 4B.

  Similar to the skeleton cell space C, the infill cell space Cj can also be divided. FIG. 36 shows a state in which the partition unit 17 is provided in the infill cell space Cj, whereby the infill cell space Cj is divided into two infill cell spaces Cj1 and Cj2. In this case, instead of the cell space table T12 (FIG. 35) defined for the infill cell space Cj described above, cell space tables T13, T14 (FIG. 37) defining each of the two infill cell spaces Cj1, Cj2. (A) and FIG. 37 (B)) are newly defined.

Seventh. Registration of processing information As described above, furniture is composed of a combination of a plurality of units (a skeleton unit and one or a plurality of infill units), and the unit is composed of one part or a combination of a plurality of parts. Furthermore, the parts are composed of one material or a combination of a plurality of materials. When the design of the furniture is completed, as described above, the dimensions of a plurality of units constituting the furniture are determined, and the dimensions of one or a plurality of parts constituting the unit are determined by determining the dimensions of the unit. By determining the dimensions of a part, the dimensions of one or more materials constituting the part are determined. Each of multiple materials is processed to the determined dimensions, parts are manufactured by combining processed multiple materials, units are manufactured by assembling multiple parts, and multiple units are combined to design The completed furniture will be completed.

  Parts manufactured by combining multiple materials can basically be manufactured by bonding the front and back materials to the front and back surfaces of the core material, and adhering the end material to the end of the core. it can. On the other hand, a unit manufactured by assembling a plurality of parts generally cannot secure strength only by bonding, so there is a hole in the surface of the part's mouth and other parts to which the mouth is joined. The joint strength can be increased by drilling a dowel hole and joining it with a wooden dowel or by using a tightening bracket.

  In the furniture design system, data representing processing information for assembling parts, such as holes and grooves to be formed in advance, can be registered in association with the parts.

  FIG. 38 shows the top plate 11 and the right side plate 14, which are parts constituting the cabinet unit 2 (see FIGS. 3 and 7), and a plurality of holes used for joining the top plate 11 and the right side plate 14. Yes. In FIG. 38, four holes are formed in each of the right side of the top plate 11 and the left side of the right side plate 14 in order to join the right side of the top plate 11 and the left side of the right side plate 14.

  3 and 7, for example, in the case of the top plate 11 of the cabinet unit 2, it is necessary to make holes for joining the left side plate 13 and the right side plate 14 on the left side and the right side of the top plate 11. is there. For this reason, the processing information is registered on the left surface and the right surface of the top plate 11, respectively.

  FIG. 39A shows the right surface of the top plate 11, that is, the surface joined to the right plate 14 (see FIG. 38). Four holes (i) to (iv) are formed in the right surface of the top plate 11.

  The number and position of the plurality of holes are determined according to the dimensions of the parts, here the top plate 11. If the hole is on the right side of the top plate 11, the number and position thereof are determined according to a predetermined rule according to the depth dimension of the top plate 11 (length from the front end to the rear end). For example, the following rules determine the number and location of holes.

-Make a hole at a specific distance A from the rear edge.
-Make a hole at a specific distance C from the front edge.
-The pitch between holes is a specific distance B, and holes are added for each distance B from the rear end.
When the additional hole reaches a position exceeding the hole at a distance C from the front end, the drilling is finished.

  According to the above-mentioned rule, referring to FIG. 39A, a hole (i) is made at a position of a distance A from the rear end (meaning that a position where the hole (i) is to be made is determined. The same shall apply hereinafter.) Next, a hole (ii) is made at a distance C from the front end. Since an additional hole is drilled at every distance B from the rear end, an additional hole (iii) is formed at a distance B from the hole (i), and an additional hole (iv) is formed at a distance B from the additional hole (iii). ) Is opened.

  When going from the additional hole (iv) to the front end by the distance B, the position of the hole (ii) that has been drilled is exceeded (the distance between the additional hole (iv) and the hole (ii) is less than B) ). For this reason, the addition of the hole ends when the additional hole (iv) is made.

  FIG. 39 (B) shows a case where the dimension of the top plate 11 in the depth direction is larger than that of FIG. 39 (A). In the case of FIG. 39 (B), the additional hole (v) is further opened at a distance B from the additional hole (iv).

  FIG. 40 shows drilling data for the right surface of the top plate 11 shown in FIG. In the hole machining data, the position of the hole to be drilled in the top plate 11 determined by the above-mentioned rules and the dimensions (hole diameter and hole depth) of the hole are defined. Further, the hole machining data also defines the positions and dimensions of holes to be drilled correspondingly in other parts joined to the top plate 11.

  The hole machining data stores data related to the machining surface, machining object, machining position, hole diameter, and hole depth. One line of data means one hole machining data.

  The “machined surface” defines the surface position to be drilled. “Processing target” stores either “self” or “partner”. Here, “self” means the top board 11. The “partner” means a specific surface of another part to which a specific processed surface of the top plate 11 is joined. In the example shown in FIG. 40, if the specific processing surface of the top plate 11 is the right surface, the “partner” means the left surface of the right plate 14. This “partner” can be automatically grasped by the parts space table described above. The “machining position” is a hole machining position (X / Y coordinate) when the front end of the hole where the hole is to be machined is regarded as a front surface and the lower left corner is used as a reference point (origin). “Hole diameter” means the diameter of the hole to be formed, and “hole depth” means the depth of the hole to be formed.

  In the case of the example shown in FIG. 38, hole machining data for each of the four holes to be formed on the right side of the top plate 11 is registered, and the right side plate corresponding to each of the four holes on the right side of the top plate 11 The drilling data for the four holes to be formed on the left surface of 14 is also registered. The positions of the four holes to be formed on the left surface of the right plate 14 are automatically determined corresponding to the four holes determined for the right surface of the top plate 11 based on the above-described rules.

  In addition to drilling data for joining parts, it is also possible to register groove processing data for forming grooves and processing data for fixing metal fittings.

  FIG. 41 shows the relationship between the two hinges K1 and K2 to be attached to the door unit 3 and the fixing position in the door unit 3 to which the hinges K1 and K2 are to be fixed and the fixing position in the right side plate 14. FIG. 42 shows the relationship between the right slide fitting 28 to be attached to the inner box unit 4B of the drawer unit 4 and the fixing position on the right end plate 24 to which the right slide fitting 28 is to be fixed and the fixing position on the right plate 14. . By designing the furniture 1 and determining its dimensions, the dimensions of the units and parts are determined as described above, and the positions where the hinges K1, K2, the right slide fitting 28, etc. should be fixed can also be determined. In the hole machining data for the hinges K1 and K2, the position, hole diameter, and hole depth of the holes to be formed in the door unit 3 and the right side plate 14 are defined. In the hole machining data for the right slide fitting 28, the positions, hole diameters and hole depths of holes to be formed in the right end plate 24 and the right side plate 14 are defined.

Eighth. System Configuration FIG. 43 shows the hardware configuration of the furniture design system. FIG. 44 shows a hardware configuration of a unit design apparatus (unit manufacturer) constituting the furniture design system.

  As described above, in the furniture design system, a plurality of types of units are designed and registered in advance, and furniture is designed by combining the registered types of units. The furniture design system includes a unit design device (unit manufacturer) 32 for designing and registering the unit described above and a furniture design for designing furniture by combining a plurality of types of units designed by the unit design device 32. Two devices, equipment (furniture maker) 33, are included.

  The unit design device 32 is constituted by a personal computer, for example. The unit design device 32 includes a CPU (Central Processing Unit) 41, and an input device 42, a display device 43, a memory 44, a hard disk 45, and a communication device 46 are connected to the CPU 41. For example, the unit design program recorded in the CD-ROM 47 is installed in the hard disk 45, so that the personal computer functions as the unit design device 32. Various windows are displayed on the display screen of the display device 43 based on the display data given from the CPU 41. The operator uses the input device 42 (keyboard, mouse, etc.) to perform clicking (selection), numerical input, and the like.

  The furniture design device 33 is also constituted by a personal computer. In FIG. 44, the reference numerals shown in parentheses indicate the hardware configuration of the furniture design apparatus 33.

  In the unit design device 32, data representing the above-described “skeleton unit” and “infill unit” used for designing furniture is created. Needless to say, these data include the above-described cell space table, parts space table, and material space table. Data representing the created unit is uploaded through the communication device 46 and the network 31 and registered (stored) in the unit database 34 connected to the network. Data representing units registered in the unit database 34 is downloaded to the furniture design device 33 via the network 31 and the communication device 56, so that the furniture design device 33 can combine units, that is, design furniture. Done.

  Taking the drawer unit 4 (pre-drawer plate unit 4A and drawer inner box unit 4B) as an example, the flow of creating the drawer unit 4 performed in the unit design device 32 will be described.

(1) Parts creation (design)
45 to 49 are used to design each of a plurality of plate parts (the bottom plate 22, the left gable plate 23, the right gable plate 24, the front plate 25, the inner front plate 26, etc.) (FIG. 8) constituting the drawer unit. The design screen is shown.

  When the unit design program is started, the personal computer functions as the unit design device 32 as described above. Referring to FIG. 45, first, “file” at the top of the initial screen is clicked. Then, “New”, “Open”, “Save As” and “Exit” characters appear. Of the “parts”, “units”, “doors”, and “drawers” that appear when “new creation” is selected, “parts” are selected.

  When “parts” is selected, a screen for selecting the basic structure or material of the parts to be designed appears as shown in FIG. Here, “solid”, “glass”, or “plywood” is selected. “Innocent” is selected when the parts are made of a single material (other than glass). “Glass” is selected when the part material is glass. “Plywood” is selected when the parts are constituted by a combination of a core material, a front surface material, a back surface material, and a lip material. Here, a case where “plywood” is selected will be described.

  When “Plywood” is selected and the “Next” button is clicked, as shown in FIG. 47, the group, manufacturer, and part number are selected for each of the core material, the front surface material (and the back surface material), and the wood end material. A screen appears. For the surface material (and back material) and the lip material, the thickness is determined by selecting the manufacturer and product number (fixed value). On the other hand, the thickness of the core material is determined by the thickness of the whole part to be input next and the thicknesses of the front surface material, the back surface material, and the end material. In the initial state, the part (plywood) is defined as having a core material, a surface material and a back material covering the front and back surfaces of the core material, and four end pieces covering each of the four side surfaces of the core material. Is done.

  Referring to FIG. 48, a screen for inputting a part thickness (plywood thickness) appears next. Here, the total thickness of the part is entered.

  Referring to FIG. 49, finally, a name (part name) about the part is input, and thereby the definition of the plywood (part) constituting the drawer inner box unit 4B is completed. By selecting the plywood, a material space table (see FIG. 22) for defining the material space circumscribing the core material, a material space table (see FIG. 18) for defining the material space circumscribing the front surface material and the back material, respectively, A material space table (see FIG. 20) that defines a material space circumscribing each of the wood ends is created. In addition, a part space table (see FIGS. 24 and 30) that defines a part space circumscribing a plywood (part) composed of a plurality of materials is also related to data and related values for each of the six target surfaces of the part space. Created excluding data. If a plurality of plates constituting the drawer inner box unit 4B are all made of plywood and all have a thickness of 20 mm, the unit will be described below using the single plate material data created here. Just go ahead. When, for example, any one of the plurality of plate materials is made to have a different thickness, another plate material data (for example, a thickness of 10 mm) may be created.

(2) Unit creation (design)
50 to 58 show design screens used for designing the drawer unit 4 (the drawer inner box unit 4B and the drawer front plate unit 4A). “Drawer” that appears by selecting “New creation” on the screen of the initial screen (FIG. 45) described above is clicked.

  In creating a unit, the following two processes are performed.

  The first processing is input of related data between the surfaces of a plurality of parts constituting the unit. In this process, what kind of (how many) parts the unit to be designed consists of is input, and if the unit is composed of multiple parts, Association input is performed. However, when the unit is composed of only one part as in the door unit 3 (see FIG. 4), the input of the related data between the surfaces of the plurality of parts constituting the unit is omitted.

  The second process is data input related to the above-described unit space and part space. In this process, it is input which surface of which part of the plurality of parts is associated with each of the six surfaces of the unit space. The second process is also performed for a unit composed of only one part (for example, door unit 3).

  Referring to FIG. 50, this screen shows the drawer inner box unit 4B to be designed in seven parts (the bottom plate 22, the left wife plate 23, the right wife plate 24, the front plate 25, the inner front plate 26, the left rail 27 and the right rail. 28) shows the screen in the initial state when configured from (see FIG. 8). An approximate position of the seven parts is input using an input device 42 (such as a mouse).

  Referring to FIGS. 51 and 52, these screens are screens for inputting the association between the surfaces of the parts. First, a specific surface of a specific part is selected as a “main surface” (FIG. 51), and then a specific surface of another specific part is selected as a “secondary surface” (FIG. 52). Thus, for example, a structure is defined in which the left surface (side surface) (shown by hatching in FIG. 52) (secondary surface) of the inner front plate 26 is in contact with the right surface (shown by hatching in FIG. 51) (main surface) of the left gable plate 23. The At this time, the left end of the inner front plate 26 which is the secondary surface may be omitted. The material space table of the left mouthpiece constituting the inner front plate 26 is deleted. By performing the same process for each of the seven parts, for example, the inner box unit 4B having the structure shown in FIG. 5 is designed.

  53 to 58 are screens for inputting surface-related data between the unit space and the parts space. Referring to FIG. 53, a rectangular parallelepiped figure representing unit space U4B of drawer inner box unit 4B is first displayed, and one of the six faces, for example, the front face is clicked and specified (FIG. 53). In hatching). Next, a part (part space) to be associated with the front surface of the specified unit space U4B and its specific surface are selected. FIG. 54 shows a state where the front surface (hatched portion) of the left gable plate 23 is selected. By selecting the front surface of the unit space U4B and the front surface of the left gable plate 23 (part space), these surfaces are associated with each other (FIG. 55). As a result, data is input to the part space table T7 (FIG. 30) of the left gable plate 23 that the front position of the left gable plate 23 (part space) is the front surface of the unit space U4B. By setting the numerical value in the “distance” column at the upper left of the screen to “0.0 mm”, it is defined that the distance between the front position of the unit space U4B and the front position of the left face plate 23 is 0 mm, that is, match (FIG. 55). ). The same operation is performed in the same manner for other parts.

  A screen for selecting whether or not the pre-drawer plate unit 4A is provided in the drawer inner box unit 4B is displayed (FIG. 56). When the pre-drawer plate unit 4A is provided, “with front plate” is selected. The height (initial value) and gap or dust (see FIG. 24) for the pre-drawing plate unit 4A (pre-drawing plate 21) are input (FIG. 57). Further, a clearance or dust (see FIG. 32) set for the drawer inner box unit 4B is input (FIG. 58).

  Through the data input using the above-described screen, the creation of the material space table, the part space table and the unit space table for the pre-drawer plate unit 4A is completed, and the material space table for the drawer inner box unit 4B is also created. Creation of a set of parts space table and unit space table is completed. The created unit space table, part space table, and material space table are registered as a set of data in the unit database 34 via the network 31 as data representing the drawer unit 4. Similarly, for the cabinet unit 2 (FIG. 3), the door unit 3 (FIG. 4), etc., the unit space table, the parts space table, and the material space table are combined into data representing the cabinet unit 2, the door unit 3 and so on. Is registered in the unit database 34 as data representing. Of course, the unit space table, the part space table, and the material space table can be created (data input) by directly operating these tables without using the input screen described above. Both data entry and data entry by manipulating the table directly can be used.

  As described above, the data representing the skeleton unit and the data representing the infill unit may be created by determining the structure of the unit (for example, the drawer inner box unit) by combining parts one by one. Prepare templates for cabinet units, drawer inner box units, door units, etc. in advance, and modify some or all of the templates (change the thickness of the plate, change the thickness of the mouthpiece, It may be created by changing the method of assembly). In any case, a set of the unit space table, the part space table, and the material space table described above is created for each of the plurality of skeleton units and infill units, and is registered in the unit database 34.

  59 to 62 show input screens for setting a cell space (creating a cell space table).

  59 and 61 show how the skeleton cell space C (FIGS. 3, 13A and 13B) is set inside the cabinet unit 2. FIG.

  In the setting of the cell space, a plurality of parts constituting the unit and which direction of the cell space is defined based on which plane of the unit space is input. 59 and 60 show a state where the cell space is set in the direction toward the opposite side (right side plate) with reference to the inner surface of the left side plate 13 constituting the cabinet unit 2. By performing the same operation for the six surfaces, the skeleton cell space C is defined inside the cabinet unit 2, and the cell space table T9 (FIG. 33) for the skeleton cell space C is created.

  61 and 62 show how the infill cell space Cj (FIG. 6) is set inside the drawer inner box unit 4B. Here, the inner surface of the left gable plate 23 of the inner box drawer unit 4B is used as a reference. , The state when the cell space is set in the direction toward the opposite side (right twill board) is shown. By performing the same operation for six sides, the infill cell space Cj is defined inside the drawer inner box unit 4B, and the cell space table T12 (FIG. 35) of the infill cell space Cj is created.

  Data representing the cell space table is also registered in the unit database 34 in the set of the unit space table, part space table, and material space table described above.

  63 to 66 show windows displayed on the display screen of the display device 53 of the furniture design device 33, and are screen transitions showing the flow when designing the furniture 1 (FIG. 2).

  A user (operator) of the furniture design apparatus 33 first accesses the unit database 34 through the network 31 and downloads data representing a unit registered in advance. By dragging and dropping an image representing the unit represented by the data representing the downloaded unit onto the design window, the furniture design, that is, the unit combination is advanced.

  For example, when a “skeleton” selection button (not shown) is clicked, images (or names) of skeleton units are displayed in a list. When an image of the cabinet unit 2 is selected and dragged and dropped into the design window, an image representing the front of the cabinet unit 2 is displayed in the design window (FIG. 63). For the dimensions (height, width, and depth) of the cabinet unit 2 (unit space U2) and the skeleton cell space C that are displayed first, initial values (standard values predetermined in the furniture design apparatus 33) are used. . The dimensions of the initial cell space C are defined in the memory 54.

  Using the input device 52 (mouse), the dimension in the height direction and the dimension in the width direction of the cabinet unit 2 can be changed in the design window. In addition, the height, width, or depth dimensions can be changed using a window (not shown) that represents the height, width, and depth displayed separately. When the height, width, and depth are changed, the displayed shape of the cabinet unit 2 is changed to have the changed height and width. Data representing the dimensions (height, width, depth) and data representing the dimensions (height, width, depth) of the cell space C according to changes in the shape (dimensions) of the cabinet unit 2 on the memory 54. Is changed.

  Next, another unit is provided (arranged) in the skeleton cell space C defined by the cabinet unit 2.

  When the drawer unit 4 which is one of the infill units is provided in the cell space C of the cabinet unit 2, an “infill” selection button (not shown) is clicked. A plurality of types of infill unit images including images of the drawer unit 4 are displayed. When the image portion of the drawer unit 4 is selected by clicking with the input device 52 and dragged and dropped to the lower part of the cell space C of the cabinet unit 2, the drawer unit 4 is placed in the lower part of the cell space C. An image schematically representing the front is additionally displayed (FIG. 64).

  As described above, when the drawer unit 4 is incorporated into the cell space C, one cell space C created by the cabinet unit 2 is divided into two cell spaces C1 and C2 (FIG. 14B). reference). The unit space U4 of the drawer unit 4 (that is, the unit space U4A and U4B of the drawer inner box unit 4B) is associated with the cell space C2. The fact that the unit space U4 is associated with the cell space C2 is stored in the memory 54. Further, the memory 54 stores the dimensions of the cell space C1 and the cell space C2.

  The unit spaces of the drawer unit 4 incorporated in the cell space C2 (that is, the unit space U4A of the drawer front plate unit 4A and the unit space U4B of the drawer inner box unit 4B) are respectively unit space tables (FIGS. 27 and 32). According to the position and dimensions. For example, by determining the position and dimensions of the unit space U4A of the drawer front plate unit 4A, as described above, the position and dimensions of the drawer front plate 21 are determined according to the part space table T4 (FIG. 24). By determining the position and dimensions, the positions and dimensions of the materials such as the core material and the surface material constituting the pre-drawing plate 21 are also determined according to the material space tables T1, T2, and T3 (FIGS. 18, 20, and 22).

  As described above, the skeleton cell space C in the initial state defined by the cabinet unit 2 is divided into two cell spaces C1 and C2 by incorporating the drawer unit 4, and the skeleton cell spaces C1 and C2 are divided. Cell space tables T10 and T11 (FIGS. 34A and 34B) are created.

  At this time, the unit space is not incorporated in the other skeleton cell space C1 (in the memory 54, data indicating that the unit space is not yet associated with the cell space C1 may be stored). Other parts can be incorporated into the cell space C1.

  When the door unit 3 is assembled at the position of the cell space C1, an image representing the door unit 3 is selected. When the image is dragged and dropped to the position of the cell space C1, an image schematically representing the front of the door unit 3 is additionally displayed at the position of the cell space C1 (FIG. 65). The design of the furniture 2 is completed (FIG. 16B).

  For example, if the right end of the image of the cabinet unit 2 in which the door unit 3 and the drawer unit 4 are incorporated is selected by clicking with the mouse, and the mouse is moved to the right while holding the click, the cabinet unit 2 , Both the door unit 3 and the drawer unit 4 are displayed with an enlarged width (FIG. 66). This is because the unit space U3 of the door unit 3 and the unit spaces U4A and U4B of the drawer unit 4 (the drawer front plate unit 4A and the drawer inner box unit 4B) are associated with the skeleton cell spaces C1 and C2 of the cabinet unit 2, respectively. This is because the positions and dimensions of the unit spaces U3, U4A, U4B are relatively determined according to the positions and dimensions of the cell spaces C1, C2, as described above. That is, when the width direction of the cell space C1 and the cell space C2 is expanded, the unit space U3 of the door unit 3 is also expanded in the width direction according to the unit space table for the door unit 3 according to the expansion of the cell space C1. (The surface position follows the cell space C1). In conjunction with the expansion of the unit space U3, the material space of the parts or materials constituting the door unit 3 is also expanded (the surface position follows). Similarly, according to the expansion of the cell space C2, the unit spaces U4A and U4B of the drawer unit 4 are also arranged in the width direction according to the unit space table for the drawer front plate unit 4A and the drawer inner box unit 4B that constitute the drawer unit 4. (The surface position follows the cell space C2). In accordance with the expansion of the unit spaces U4A and U4B, the part space (surface position) of a plurality of parts constituting the front drawer unit 4A and the drawer inner box unit 4B and the material space (surface position) of a plurality of materials constituting the parts are also provided. fluctuate.

  When the dimensions (height, width, and depth) of the cabinet unit 2 are determined, the dimensions of a large number of materials for producing the cabinet unit 2 are determined as described above. In other words, when the furniture design is completed using the furniture design device 33, the dimensions of each material necessary for actually producing the designed furniture can be immediately provided to the material manufacturer (material manufacturer). In addition, machining information on the parts necessary for the designed furniture (for example, the above-described hole machining data (see FIGS. 38, 39A, 39B, and 40)) can be immediately provided to the material processing manufacturer. The time required to create the data necessary to actually create the designed furniture can be greatly reduced.
