Description

  The present invention relates to a wood part that can be used by combining a plurality of parts by actual joining.

  Conventionally, in a wood part, one of a pair of end faces exposed on opposite sides is provided with a convex male part continuous in the longitudinal direction of the end face, and the other end of the pair of end faces Techniques for forming respective female grooves having a groove shape continuous in the longitudinal direction are known. In that case, it is possible to combine a plurality of the wood parts (that is, to make an actual joint) by fitting the male real part to the female real part.

  Here, in this kind of wood parts, a pair of outer peripheral surfaces (hereinafter also referred to as an upper surface and a lower surface) parallel to a plane passing through the male part and the female part are identical to each other at the time of actual joining. It is often arranged on a plane. However, in this type of wood part, it is also considered that the upper surface or the lower surface is not arranged on the same plane at the time of the actual joining. For example, Patent Document 1 proposes that the intervals from the male real part and the female real part to the lower surface are equal for each part, and the intervals from the male real part and the female real part to the upper surface are different for each part. . In that case, when each part is actually connected, the lower surface is disposed on the same plane, but the upper surface constitutes irregularities corresponding to the difference in the interval. For this reason, when these parts that are actually joined to each other are used as a siding plate and the lower surface is attached to a stud, irregularities can be freely formed on the wall surface.

Japanese Utility Model Publication No. 63-21354

  However, there is a demand for the wood parts that are jointed in this way to be applied to modeling with a higher degree of freedom. Then, this invention aims at improving the freedom degree of the shaping | molding using the said wood part in the wood part to be succeeded.

  In the present invention, at least one of a pair of end faces (2, 3, 22, 23, 42, 43, 72, 73) exposed on the opposite sides is provided in a fixed direction (hereinafter referred to as a first end face). Convex-shaped male part (5, 9, 25, 29, 45, 49, 75) that is continuous in the direction) is formed in a concave groove shape that is continuous in the fixed direction on at least the other of the pair of end faces. Each of the first female real parts (6, 26, 44, 46, 76), and the pair of end faces are configured to be able to be joined to other wood parts. The outer peripheral surfaces (7, 27, 47, 52, 77) that are non-parallel to each of the end surfaces, and a concave groove-shaped second surface on which the same shape member as the male part can be fitted. It has two female real parts (11, 31, 51, 53, 81).

  For this reason, in the wood part of the present invention, for example, when two wood parts are actually joined, the other end face of the other wood part has the male part of the one end face of the one wood part. 1 Fit to the female real part. By carrying out like this, a some wood part can be actually spliced along the 2nd direction which connects a male real part and a 1st female real part. Further, the wood parts of the present invention are combined with each other not only by this method but also by a method in which the male part of one wood part is fitted to the second female part of the other wood part and three-dimensionally joined. It becomes possible. In other words, the three-dimensional actual joining method is a method of actual joining in a direction intersecting a plane defined by the first direction and the second direction. Therefore, if the wood part of this invention is used, the freedom degree of modeling will improve.

  In addition, when the wood part has a pair of outer peripheral surfaces (47, 52) exposed on opposite sides and has the second female real part (51, 53) on each of the outer peripheral surfaces, Such additional effects are produced. In that case, a pair of outer peripheral surfaces on which the second female real parts are formed are provided so as to be exposed on opposite sides. The male real part can be fitted to the second female real part formed on either outer peripheral surface. Therefore, if such wood parts are used, the degree of freedom of modeling is further improved.

  In any one of the wood parts, the male part (5, 25, 45) provided on the one end surface (2, 22, 42) and one of the outer peripheral surfaces (7, 27, 47) is equal to the distance between the first female real part (6, 26, 46) provided on the other end surface (3, 23, 43) and the one outer peripheral surface as follows. Further effects are produced. In that case, when a plurality of the male real parts are fitted to the first female real part and combined, the one outer peripheral surface of each wood part is disposed on the same plane. For this reason, if the outer peripheral surface disposed on the same plane is attached to a wall surface, a stud, a floor, a ceiling, etc., each wood part is attached to the wall surface or It is possible to attach it well to studs, floors, ceilings, etc.

  In any one of the wood parts, the direction in which the male part (5, 25, 45) protrudes and the direction in which the second female part (11, 31, 51, 53) is recessed are When orthogonal to each other when viewed from a certain direction, the following further effects are produced. That is, in this case, when the four wood parts are combined so that the male real part (5, 25, 45) is fitted to the second female real part (11, 31, 51), A square columnar solid having a square columnar penetrating space is formed. That is, the male part in each of the four wood parts is fitted into the second female part of the adjacent wood part, so that the four wood parts form a stable three-dimensional shape. Therefore, if such wood parts are used, the degree of freedom of modeling is further improved, and the stability of the modeled object is also improved.

  Here, the “quadrangular columnar shape” is not limited to a quadrangular column in a strict sense, and may not be strictly a quadrangular column as long as a desired effect is achieved. For example, unevenness corresponding to a male real part or a female real part may exist, and a part constituted by a curved surface may be included.

  Further, in any one of the wood parts, when the plurality of second female real parts (31, 51) are arranged in parallel on at least one of the outer peripheral surfaces (27, 47), the following further effects are produced. . In that case, the male part can be fitted to a desired one of the plurality of second female parts provided in parallel on the outer peripheral surface. Therefore, if such wood parts are used, the degree of freedom of modeling is further improved.

  Further, in any one of the wood parts, when at least one of the end faces (42, 43) has a plurality of the first female real parts (44, 46) in parallel, the following further effects are produced. In that case, the male part can be fitted to a desired one of the plurality of first female parts provided in parallel to the end face. For this reason, changing the arrangement of the outer peripheral surface of the plurality of wood parts actually joined along the second direction, such as providing irregularities, is also possible by appropriately changing the first female real part to fit the male real part. It can be easily executed by selecting. Therefore, if such wood parts are used, the degree of freedom of modeling is further improved.

  Hereinafter, embodiments for carrying out the invention will be described with reference to the drawings. In the following description, the directions of up / down / left / right and front / rear are defined as necessary. However, each of these directions is only a direction defined in order to briefly describe the relative positional relationship between the respective parts constituting the wood part. In actual use of wood parts, the direction in which the wood parts are directed is arbitrary. For example, it is used in the state where the vertical direction defined below does not match the vertical direction due to gravity. It doesn't matter.

[1. First Embodiment]
[1-1. Constitution]
A wood part 1 according to the first embodiment shown in FIG. 1 is formed by cutting and cutting a single piece of wood, and has a substantially rectangular parallelepiped shape as a whole. A male part 5 and a first female part 6 are respectively formed on the end face 2 and the end face 3 exposed on the opposite sides of the wood part 1.

  The end surfaces 2 and 3 are configured in a rectangular shape having parallel long side directions (hereinafter also referred to as right and left directions: an example of a certain direction and a first direction), and the male part 5 is one of the short side directions on the end surface 2. It protrudes perpendicularly | vertically with respect to the end surface 2 from the position biased to the side, and is comprised by the convex shape continuous in the left-right direction. Hereinafter, the direction in which the male part 5 is provided in a biased manner is also referred to as an upward direction, and the direction from the end face 3 toward the end face 2, that is, the direction in which the male part 5 protrudes is also referred to as a forward direction.

  The first female real part 6 is formed on the end face 3 in a concave groove shape that is continuous in the left-right direction (strictly, a rectangular groove shape cut forward). The male real part 5 and the first female real part 6 are provided over the entire left and right direction of the end surfaces 2 and 3. The vertical width of the male real part 5 and the first female real part 6 is such that the male real part 5 in another similar wood part 1 can be fitted to the first female real part 6 and is bonded when fitted. Even if it does not use an agent etc., it is set as the width | variety which can suppress that the said fitting disengages easily.

  Here, the upper outer peripheral surface orthogonal to the end surfaces 2 and 3 of the wood part 1 and parallel to the left-right direction is defined as the upper surface 7. The distance from the upper surface 7 to the male real part 5 is equal to the distance from the upper surface 7 to the first female real part 6. That is, when the male part 5 is fitted to the first female part 6, the upper part 7 of each wood part 1 is disposed on the same plane as shown in FIG. A first female real part 6 is arranged.

  The upper side surface of the male part 5 extends rearward from the end surface 2 by being connected to a notch 8 formed by cutting the upper surface 7 into a rectangular parallelepiped shape. The upper inner wall surface of the first female real part 6 is connected to the lower side surface of the male real part 9 formed by extending the upper surface 7 rearward.

  When the male part 5 is fitted to the first female part 6 and the plurality of wood parts 1 are actually joined with the upper surface 7 aligned, as shown in FIG. The sizes of the notch portion 8 and the male solid portion 9 are designed so that the two are fitted together and spliced together. Further, the second female real part 11 that is continuous in the left-right direction is formed on the upper surface 7 in a concave groove shape (strictly, a rectangular groove shape) by cutting the upper surface 7 downward. The width and depth of the second female real part 11 are the same as those of the first female real part 6. On the other hand, the lower surface 12 as a lower outer peripheral surface orthogonal to the end surfaces 2 and 3 in the wood part 1 and parallel to the left-right direction does not form a female real part, and is configured in a smooth flat shape.

[1-2. effect]
(1A) The wood part 1 configured as described above can be joined to the plurality of wood parts 1 in the front-rear direction by fitting the male part 5 to the first female part 6. At this time, the upper surface 7 and the lower surface 12 are disposed on the same plane. Further, at this time, the male part 9 is fitted into the notch part 8 and spliced together, so that the connection state of each wood part 1 is further stabilized.

  (1B) In order to maintain such an actual joint state (hereinafter also referred to as a first actual joint state) more stably, for example, a wood screw 19 as shown in FIG. 3A is used. A fixing method can be applied. In the example shown in FIG. 3A, a wood screw 19 is screwed from the upper surface 7 side so as to penetrate the male real part 5 fitted to the first female real part 6. This upper surface 7 is the upper surface 7 in the wood part 1 which has the 1st female real part 6 which the male real part 5 fitted. In this case, the two wood parts 1 in the first joint state can be satisfactorily fixed by the wood screw 19, and the two joint parts can be stably maintained.

  In this fixing method, as the wood screw 19, a round head wood screw, a flat head wood screw, or a round head wood screw can be used. However, in order to flatten the shape on the upper surface 7 side after fixing, the head is arranged on the same plane as the upper surface 7 by using a countersunk wood screw 19 as illustrated in FIG. It is desirable to screw it in until it is installed. Moreover, when it is not necessary to arrange | position the upper surface 7 of each wood part 1 on the same plane, the real joint which makes the male real part 9 fit to the 1st female real part 6 may be made.

  (1C) Moreover, the example shown to FIG. 3 (B) is the case where the some wood part 1 in a 1st joint state is fixed to the wall surface 99 (it may be a stud, a ceiling surface, and a floor surface). Show. When the wood part 1 is disposed so that the upper surface 7 is in contact with the wall surface 99, the wood screw 19 can be screwed from the lower surface 12 side so as to penetrate the male part 9 and screw into the wall surface 99. . For this reason, the wood part 1 is fixed to the wall surface 99 satisfactorily.

  At this time, if a flat head is used as the wood screw 19 and screwed until the head is disposed on the same plane as the end surface on the lower surface 12 side of the male real part 9, the first female real part 6 is formed. The male part 5 of the other wood part 1 can be easily fitted. As described above, when a plurality of wood parts 1 are actually joined along the wall surface 99, the wood parts 1 may be fixed to the wood parts 1 by the wood screws 19. May be made.

  (1D) Moreover, the wood part 1 is provided with the 2nd female real part 11 on the upper surface 7, and the real joint which makes the male real part 5 or 9 fit to this 2nd female real part 11 is also possible. For this reason, it is possible to three-dimensionally join a plurality of wood parts 1 not only in the front-rear direction but also in the up-down direction, and the degree of freedom of modeling is improved favorably. The direction in which the second female real part 11 is cut (that is, the direction in which the second female real part 11 is cut) and the direction in which the male real part 5 protrudes are orthogonal to each other when viewed from the left-right direction. For this reason, as shown in FIG. 4, four wood parts 1 can be combined so that the male real part 5 may fit in the 2nd female real part 11 of the adjacent wood part 1. FIG. In this case, it is possible to configure a solid having a square columnar space 20 surrounded by the four upper surfaces 7. The solid is a quadrangular prism-shaped solid having four lower surfaces 12 on the outer peripheral surface, and the space 20 penetrates the solid in the axial direction.

  In this case, the male part 5 in each of the four wood parts 1 is fitted into the second female part 11 of the adjacent wood part 1, so that the four wood parts 1 form a stable three-dimensional shape. To do. Therefore, if the wood part 1 of this embodiment is used, the freedom degree of modeling will improve further and the stability of the molded article will also improve.

  The above-mentioned “quadrangular columnar shape” is not limited to a square column in a strict sense, and may not be strictly a quadrangular column as long as a desired effect is achieved. That is, as shown in FIG. 4, there may be irregularities corresponding to the male real part 9 or the first female real part 6 or the notch part 8. Further, the wood part 1 of the present embodiment is in one wood part 1 in an actual joint state (hereinafter also referred to as a second actual joint state) in which the male real part 5 is fitted to the second female real part 11. Although it is designed so that a gap is formed between the end surface 2 and the upper surface 7 of the other wood part 1, it may be designed so that such a gap is not formed. Further, as shown in FIG. 4, when four wood parts 1 are joined together, the lower surface 12 and the end surface 3 constituting the solid outer peripheral surface may be designed to be arranged on the same plane. Good.

  (1E) When the wood part 1 is in the first joint state, the upper surface 7 and the lower surface 12 are disposed on the same plane. For this reason, if the upper surface 7 or the lower surface 12 is attached to a wall surface, a stud, a floor, a ceiling or the like (hereinafter referred to as a wall surface or the like), the respective wood parts 1 are maintained in a state in which the respective wood parts 1 are actually joined. Can be satisfactorily attached to a wall surface or the like.

  This effect can also occur when combined with wood parts of different sizes. The wood part 1 shown in FIG. 5 is in a first joint state in which other wood parts 21 having different sizes are mixed. The wood part 21 is larger in the front-rear and up-down directions than the wood part 1, but the distance from the upper surface 27 to the male real part 25 and the distance from the upper surface 27 to the first female real part 26 are from the upper surface 7 in the wood part 1. It is equal to the distance to the male real part 5 and the distance from the upper surface 7 to the first female real part 6. This wood part 21 also has end faces 22 and 23 exposed on the opposite side in the front-rear direction. On the end face 22, a male part 25 having the same size as the male part 5 and a notch part 28 having the same size as the notch part 8 are formed. A first female real part 26 having the same size as the first female real part 6 and a male real part 29 having the same size as the male real part 9 are formed on the end face 23.

  Further, on the upper surface 27 of the wood part 21, second female real parts 31 that are continuous in the left-right direction are formed in two rows in parallel, and are formed in a concave groove shape (strictly, a rectangular groove shape) in which the upper surface 27 is cut downward. Has been. The width of the second female real part 31 (that is, the size in the front-rear direction) is the same as that of the second female real part 11, but the depth is deeper than that of the second female real part 11. When the male part 5 is fitted, the depth is such that the end surface 2 contacts the upper surface 27. On the other hand, the lower surface 32 of the wood part 21 does not form a female real part like the lower surface 12 of the wood part 1, and is configured in a smooth flat shape.

  In the example of FIG. 5, the male part 5 of the wood part 1 is fitted to the first female part 26 of the wood part 21, and the male part 25 of the wood part 21 is fitted to the first female part of the other wood part 1. The part 6 is fitted. Then, the notch 8 and the male part 29 of the wood part 1 are joined together, and the male part 9 and the notch 28 of the other wood part 1 are joined together. Therefore, also in this case, the first actual joint state is stably maintained.

  The distance from the upper surface 27 to the male real part 25 and the distance from the upper surface 27 to the first female real part 26 are the distance from the upper surface 7 to the male real part 5 and the distance from the upper surface 7 to the first female real part. Since the distance is equal to 6, the upper surfaces 7, 27, and 7 are arranged on the same plane in the first joint state. For this reason, fixation to a wall surface etc. is also easy. Further, at this time, the distance between the lower surface 32 and the upper surface 27 in the wood part 21 is larger than the distance between the lower surface 12 and the upper surface 7 in the wood part 1, so that the lower surface 12 and the lower surface 32 constitute an uneven surface. Therefore, it is easy to form irregularities on the wall surface. Furthermore, two second female real parts 31 are formed on the upper surface 27 of the wood part 21 in parallel. For this reason, the male part 5 of the wood part 1 can be fitted to a desired one of the two second female parts 31. Therefore, if such a wood part 21 is used, the degree of freedom of modeling is further improved.

  (1F) Moreover, both the wood part 1 and the wood part 21 are comprised by the same polygonal column shape in any part in the cross-sectional shape perpendicular | vertical to the left-right direction. For this reason, the wood part 1 and the wood part 21 can be easily prepared by cutting a square or the like that is long in one direction (corresponding to the left-right direction).

[2. Second Embodiment]
[2-1. Difference from the first embodiment]
Similarly to the wood part 1, the wood part 41 of the second embodiment shown in FIG. 6 has a cross-sectional shape perpendicular to the left-right direction in the same polygonal column shape at any part, and includes end faces 42 and 43 on the front and rear. The upper surface 47 and the lower surface 52 are provided in the same manner as in the first embodiment. The same is true in that a male part 45 is formed on the end face 42, a male part 49 is formed on the end face 43, and a notch 48 connected to the male part 45 is formed on the upper surface 47.

  However, a plurality of first female real parts 46 are formed on the end face 43, a plurality of first female real parts 44 are formed on the end face 42, and a plurality of second female real parts 51 are formed on the upper surface 47. In this respect, the wood part 41 is different from the wood part 1 in that the second female real part 53 is also formed on the lower surface 52. Hereinafter, the difference will be mainly described.

  The positional relationships and sizes of the end faces 42, 43, the male part 45, the notch part 48, the upper surface 47, and the male part 49 are as follows. This is the same as the positional relationship and size between the upper surface 7 and the male part 9. On the end face 42, first grooved female portions 44 that are continuous in the left-right direction are formed in two rows in parallel. On the end face 43, first female real parts 46 in the shape of concave grooves that are continuous in the left-right direction are formed in parallel in three rows. In addition, every 1st female real part 46 is formed in the rectangular groove shape cut out ahead like the 1st female real part 6 in the timber part 1. FIG. Moreover, every 1st female real part 44 is formed in the rectangular groove shape cut back.

  The first female real part 46 provided at the position closest to the upper surface 47 (that is, the uppermost row) is connected to the lower side surface of the male real part 49 on the upper inner wall surface, similarly to the first female real part 6 in the wood part 1. Has been. The upper inner wall surface of the first female real part 44 provided at the position closest to the upper surface 47 (that is, the uppermost row) is also connected to the lower side surface of the male real part 45.

  However, the first female real part 46 in the uppermost row in the wood part 41 is formed deeper than the other first female real parts 46 and the first female real part 6 in the wood part 1. Therefore, as shown in FIG. 7A, when the plurality of wood parts 41 are brought into the first joint state by fitting the male part 45 to the first female part 46 in the uppermost row, Before the part 45 is fitted to the back of the first female real part 46, the male real part 49 is spliced to the notch part 48. In the wood part 41, the second female real part 51 is formed deeper than the second female real part 11 of the wood part 1, and the second real joint in which the male real part 45 is fitted to the second female real part 51. In the state, it is designed so that there is no gap between the end surface 42 of one wood part 41 and the upper surface 47 of the other wood part 41.

  Specifically, on the upper surface 47 of the wood part 41, a second female real part 51 continuous in the left-right direction is arranged in two rows in parallel, and a concave groove shape in which the upper surface 47 is cut downward (strictly, a rectangular groove shape). ). The depth by which each second female real part 51 is cut downward is larger than the protruding amount of the male real part 45 with respect to the end face 42, which is larger than the protruding amount of the male real part 49 with respect to the end face 43. On the lower surface 52 of the wood part 41, a row of second female real parts 53 continuous in the left-right direction is formed in a concave groove shape (strictly, a rectangular groove shape) in which the lower surface 52 is cut upward. The depth at which the second female real part 53 is cut upward is also larger than the protruding amount of the male real part 45 with respect to the end face 42 and the protruding amount of the male real part 49 with respect to the end face 43.

[2-2. effect]
According to the second embodiment described above in detail, in addition to the effects (1A) to (1F) of the first embodiment described above, the following effects can be obtained.

  (2A) The first female real part 46 in the uppermost row is formed deeper than the first female real part 6 in the wood part 1. For this reason, the male part 49 and the notch part 48 can be reliably spliced together.

  (2B) In the second joint state, there is no gap between the end face 42 of one wood part 41 and the upper surface 47 of the other wood part 41 (see FIGS. 8A and 8B). The second actual joint state can be further stabilized.

  (2C) A plurality of first female real parts 46 are formed on the end face 43. For this reason, the male real part 45 or 49 can be fitted to a desired one of the plurality of first female real parts 46. For this reason, it is also possible to change the arrangement of the upper surface 47 or the lower surface 52 of the plurality of wood parts 41 that are actually spliced along the front-rear direction. It can be easily executed by appropriately selecting the real part 46. Therefore, if such a wood part 41 is used, the degree of freedom of modeling is further improved.

  A plurality of first female real parts 44 are also formed on the end face 42, and the male real part 49 or 45 can be fitted to the desired first female real part 44. For this reason, giving a change, such as providing unevenness, in the arrangement of the upper surface 47 or the lower surface 52 in the plurality of wood parts 41 that are actually spliced along the front-rear direction means that the first female part 49 or 45 is fitted. It can be easily executed by appropriately selecting the real part 44. Therefore, if such a wood part 41 is used, the degree of freedom of modeling is further improved.

  For example, FIG. 7B shows that the male part 45 is fitted to the first female part 46 in the second row from the top of the other wood part 41, and the male part 49 is further positioned on the top of the other wood part 41. This is an example in which the first female real part 44 of the row is fitted. FIG. 7C shows that the male part 45 is fitted to the first female part 46 in the third row from the top of the other wood part 41, and the male part 49 is further placed on the other wood part 41. It is the example fitted to the 1st female real part 44 of the 2nd row from. In the wood part 41 of the present embodiment, such a first actual joining state can also be realized.

  In addition, when it is set as the actual joint state shown in FIG.7 (B) or FIG.7 (C), the upper surface 47 and the lower surface 52 in the wood parts 41 of both ends among the three wood parts 41 are on the same plane. The dimension of each part in the wood part 41 is designed so that it may be arrange | positioned. That is, the notch portion 48 and the two first female real portions 44 are arranged at equal intervals, and the three first female real portions 46 are also arranged at equal intervals, and the arrangement intervals of both are equal.

  (2D) The wood part 41 is provided with two rows of second female real parts 51 on the upper surface 47, and real joining in which the male real part 45 or 49 is fitted to any second female real part 51 is possible. . For this reason, the freedom degree of modeling improves further. Then, similarly to the first embodiment, four wood parts 41 may be combined so that the male part 45 fits into the second female part 51 of the adjacent wood part 41.

  In this case, when each male solid part 45 is fitted to the second female real part 51 on the end face 43 side, as shown in FIG. 8A, a relatively large square columnar space 60 surrounded by the upper surface 47. It is possible to construct a solid having On the other hand, when each male solid part 45 is fitted to the second female real part 51 on the end face 42 side, a relatively small square columnar space 60 surrounded by the upper surface 47 is formed as shown in FIG. It is possible to construct a solid having the same. In the example shown in FIGS. 8A and 8B, the space 60 is formed in a substantially square shape in a side view, but the male part 45 in the pair of wood parts 41 arranged opposite to each other is disposed on the end face 42 side. When the second female real part 51 is fitted and the male real part 45 of the other pair of wood parts 41 is fitted to the second female real part 51 on the end face 43 side, the space 60 is configured to be substantially rectangular in side view. Is done.

  (2E) In the example shown in FIG. 8B, the lower surface 52 of each wood part 41 and the end surface 43 of the wood part 41 to which the wood part 41 is connected are arranged on the same plane. It can be closer to a quadrangular prism. Such a wood part 41 may be configured to be able to be connected to a wood part having a different thickness (that is, a distance between the upper surface 47 and the lower surface 52). When the second female real part 51 corresponding to the wood part to be joined is actually joined, the lower surface and the end surface 43 of the wood parts having different thicknesses may be arranged on the same plane. .

  (2F) In the wood part 41, since the first female real parts 44 and 46 are formed on the end faces 42 and 43, respectively, the first female real parts 44 and 46 can be used as follows. it can. For example, as shown in FIG. 9, when a plurality of wood parts 41 in the first joint state shown in FIG. 7A are fixed to an indoor wall surface with the end surface 43 facing upward, Concavities and convexities corresponding to the first female real part 46 are present on the end surface 43 serving as the upper surface. When the hanger hook or the like is hooked on the wall surface, the hook or the like can be satisfactorily locked to the unevenness.

  (2G) The wood part 41 includes the second female real part 53 on the lower surface 52, and a real joint in which the male real part 45 or 49 is fitted to the second female real part 53 is possible. For this reason, the freedom degree of modeling improves further.

[3. Other Embodiments]
As mentioned above, although the form for implementing this invention was demonstrated, this invention is not limited to the above-mentioned embodiment, It can implement in various deformation | transformation.

  (3A) In the above-described embodiment, the pair of end faces 2, 3 and the like exposed on the opposite sides face each other in the 180 ° opposite direction, but the present invention is not limited to this. For example, as long as the male real part and the first female real part can be formed so that they can be connected to each other, they do not necessarily have to face in the opposite direction of 180 °.

  For example, in the wood part 71 of the third embodiment shown in FIG. 10A, the pair of end surfaces 72 and 73 intersect the upper surface 77 at an angle of 120 °. The pair of end surfaces 72 and 73 intersect the lower surface 82 at an angle of 60 °. That is, in this embodiment, the angle formed by the pair of end faces 72 and 73 is 120 °.

  The end surface 72 is formed with a male part 75 projecting in a direction along the upper surface 77 (that is, forward), and the end surface 73 is formed with a first female part 76 cut forward. The male real part 75 is formed in a convex shape that is continuous in the left-right direction (an example of the constant direction and the first direction), and the first female real part 76 is formed in a concave groove shape that is continuous in the left-right direction. The size of the male real part 75 is substantially equal to the size of the internal space of the first female real part 76, and the male real part 75 can be fitted to the first female real part 76, and at the time of fitting, an adhesive or the like The size is such that the fitting is not easily disengaged even without using. Further, the distance between the upper surface 77 and the male part 75 is equal to the distance between the first female part 76 and the lower surface 82.

  For this reason, as shown in FIG. 10 (B), the upper surface 77 and the lower surface 82 are alternately directed to the opposite sides, and the male part 75 in each wood part 71 is the first female part 76 of the adjacent wood part 71. The plurality of wood parts 71 can be actually joined in the front-rear direction. At this time, the upper surface 77 and the lower surface 82 on each side are disposed on the same plane.

  Further, a second female real part 81 cut in parallel with the end face 73 is formed on the upper surface 77 of the wood part 71. The second female real part 81 is also formed in a concave groove shape continuous in the left-right direction. The size of the second female real part 81 is equal to the size of the first female real part 76, and the distance between the second female real part 81 and the end surface 73 is equal to the distance between the first female real part 76 and the upper surface 77. .

  For this reason, when the three wood parts 71 are combined so that the male real part 75 fits into the second female real part 81 of the adjacent wood part 71, the triangular prism-shaped space surrounded by the three upper surfaces 77 A solid with 80 can be constructed. As described above, in the present invention, when the second female real part is formed in a direction corresponding to the angle formed by the pair of end faces is different from 180 °, a solid such as a triangular prism shape, a pentagonal prism shape, or a hexagonal prism shape is formed. It becomes possible to do.

  (3B) Moreover, in each said embodiment, although a pair of end surface 2, 3 grade | etc., Is comprised in planar shape, it is not limited to this. For example, at least one of the pair of end surfaces may be gently curved so as to be convex outward or inward. In that case, the joined wood parts do not adhere to each other, but there is no problem depending on the application.

  (3C) Moreover, the process which roughens a surface may be given to the outer peripheral surface of a male real part, and the inner wall surface of a 1st female real part or a 2nd female real part. In that case, it is possible to more favorably suppress the disconnection of the real joint between the male real part and the first female real part or the second female real part.

  (3D) Moreover, the male part 9 in the first embodiment, one of the male parts 45 and 49 in the second embodiment, or the first female part 44, 46 or the second female in the second embodiment. Part of the real parts 51 and 53 may be omitted. Furthermore, the shape, size, and formation position of the male part, the first female part, and the second female part in each of the above embodiments may be changed as appropriate. The male real part may be a convex part to be joined, and the female real part may be a concave groove to be joined. However, if the thickness of the wood around the first female real part or the second female real part has an appropriate thickness, the processing during the production of the wood part becomes easier.

  (3E) In each of the embodiments described above, actual joining is possible in the front-rear and up-down directions. However, for example, by adopting a male real part and a first female real part over two adjacent sides as described in Japanese Patent No. 3461569 The wood parts may be configured to be able to be joined in the left-right direction.

  (3F) A plurality of functions of one constituent element in the embodiment may be realized by a plurality of constituent elements, or a single function of one constituent element may be realized by a plurality of constituent elements. . Further, a plurality of functions possessed by a plurality of constituent elements may be realized by one constituent element, or one function realized by a plurality of constituent elements may be realized by one constituent element. Moreover, you may abbreviate | omit a part of structure of the said embodiment. In addition, at least a part of the configuration of the embodiment may be added to or replaced with the configuration of the other embodiment. In addition, all the aspects included in the technical idea specified only by the wording described in the claim are embodiment of this invention.
