Description

フレーム構造体Frame structure
　本発明は、三次元フレーム構造を形成するフレーム構造体に関する。 The present invention relates to a frame structure that forms a three-dimensional frame structure.
　従来から、三次元のフレーム構造体として、たとえば、美術分野においてワイヤを用いて三次元のフレーム構造体を作製するワイヤフレームアートが知られている。 Conventionally, as a three-dimensional frame structure, for example, wire frame art for producing a three-dimensional frame structure using a wire in the art field is known.
　ところが、この種のフレーム構造体では、十分な強度や剛性を確保するため、断面が円形状でかつ径が大きいワイヤが用いられることが一般的である。このため、サイズが大きいフレーム構造体を運搬する際、運搬効率がきわめて低下するという問題がある。 However, in this type of frame structure, a wire having a circular cross section and a large diameter is generally used to ensure sufficient strength and rigidity. For this reason, when carrying a frame structure with a large size, there is a problem that carrying efficiency is extremely lowered.
　そこで、本発明は、運搬効率が高いフレーム構造体を提供することを目的とする。 Therefore, an object of the present invention is to provide a frame structure with high transport efficiency.
　上記目的を達成するため、本発明のフレーム構造体は、有端状または無端状のテープと、前記テープを折り曲げてなる複数の折曲部を、少なくとも１つの集約箇所で集約する集約手段と、を備え、前記集約箇所を頂部に含む三次元フレーム構造がテープにより形成されている。前記テープを折り曲げた折曲部を少なくとも１つの集約箇所で集約し、前記集約箇所を頂部に含む三次元フレーム構造がテープにより形成されているため、前記テープの曲げ剛性の異方性により三次元フレーム構造を容易に変形可能な外力作用方向が存在することとなる。そして、前記外力作用方向を利用することにより、前記フレーム構造体の組立、収納および展開が簡便となるため、前記フレーム構造体の運搬効率を向上させることができる。 In order to achieve the above object, the frame structure of the present invention comprises an endless or endless tape, and a concentrating means for consolidating a plurality of bent portions formed by bending the tape at at least one aggregation location. The three-dimensional frame structure including the aggregated portion at the top is formed of a tape. The bent portion obtained by bending the tape is aggregated at at least one aggregated portion, and a three-dimensional frame structure including the aggregated portion at the top is formed of the tape. There is an external force acting direction that can easily deform the frame structure. Then, by using the external force acting direction, the frame structure can be easily assembled, stored, and deployed, so that the transport efficiency of the frame structure can be improved.
　また、前記折曲部は、前記テープの一部をローラに巻回することで構成されていることが好ましい。前記テープの一部を前記ローラに巻回することにより前記折曲部が構成されているため、前記ローラにより前記テープを摺動させることで円滑に前記テープを繰り出すことができる。 Further, it is preferable that the bent portion is configured by winding a part of the tape around a roller. Since the bent portion is configured by winding a part of the tape around the roller, the tape can be smoothly fed out by sliding the tape with the roller.
　また、前記テープを繰り出し可能に巻き取る巻取手段をさらに備えることが好ましい。前記巻取手段により前記テープを繰り出し可能に巻き取ることが可能であるため、前記テープを巻き取ることで前記三次元フレーム構造をさらにコンパクトに収納することができる。 Further, it is preferable to further include a winding means for winding the tape so that the tape can be fed out. Since the tape can be taken up by the winding means, the three-dimensional frame structure can be stored more compactly by winding the tape.
　また、前記三次元フレーム構造は、四面体であることが好ましい。前記三次元フレーム構造が四面体であるため、最小の頂点数により前記三次元構造を構成することができる。 The three-dimensional frame structure is preferably a tetrahedron. Since the three-dimensional frame structure is a tetrahedron, the three-dimensional structure can be configured with a minimum number of vertices.
　また、前記テープは、金属からなることが好ましい。高剛性かつ弾性に富む金属からなるテープを用いて前記三次元構造を形成することにより、前記フレーム構造体の強度および収納性を両立させることができる。 The tape is preferably made of metal. By forming the three-dimensional structure using a tape made of a metal having high rigidity and elasticity, both the strength and the storage property of the frame structure can be achieved.
　このように、本発明によれば、運搬効率が高いフレーム構造体を提供することができる。 Thus, according to the present invention, a frame structure with high transport efficiency can be provided.

A pair of drive rollers 51a, 51b, 51d, 51e, 51g, and 51h (hereinafter collectively referred to as a pair of drive rollers 51) and a pair of drive rollers 51 that sandwich the tape 12 from the thickness direction, respectively. It is composed of three sliding guides 52a to 52c (hereinafter also collectively referred to as sliding guides 52) that are rotatably supported.
　一対の駆動ローラ５１ａ、５１ｂ、５１ｄ、５１ｅ、５１ｇ、５１ｈは、円柱形状を有しており、周面上にテープ１２を巻回することにより折曲部２３ａ、２３ｂ、２３ｄ、２３ｅ、２３ｇ、２３ｈをそれぞれ形成する。この一対の駆動ローラ５１は、上面視すると上下方向に一対配置されるとともに四面体の底面頂部Ｂに各２つ上下方向に配置されている。 The pair of drive rollers 51a, 51b, 51d, 51e, 51g, 51h has a columnar shape, and the bent portions 23a, 23b, 23d, 23e, 23g, 23h is formed. A pair of the driving rollers 51 are arranged in the vertical direction when viewed from above, and two are arranged in the vertical direction on the bottom face top B of the tetrahedron.
　また、一対の駆動ローラ５１は、モータ（図示省略）により回転駆動が可能であり、駆動ローラ５１が回転することによりテープ１２の繰り出しおよび繰り込みを行う。 Further, the pair of drive rollers 51 can be driven to rotate by a motor (not shown), and the tape 12 is fed and retracted as the drive roller 51 rotates.
　摺動ガイド５２は、四面体の底面頂部Ｂに各１つ配置され、一対の駆動ローラ５１ｈと一対の駆動ローラ５１ａは摺動ガイド５２ａが、一対の駆動ローラ５１ｂと一対の駆動ローラ５１ｄは摺動ガイド５２ｂが、一対の駆動ローラ５１ｅと一対の駆動ローラ５１ｇは摺動ガイド５２ｃがそれぞれ回動可能に支持する。 One sliding guide 52 is disposed on each bottom face top B of the tetrahedron, the pair of driving rollers 51h and the pair of driving rollers 51a are sliding guides 52a, and the pair of driving rollers 51b and the pair of driving rollers 51d are slid.

It is comprised from the horizontal board part 54 which supports the roller 51 so that rotation is possible. The vertical plate portion 53 and the horizontal plate portion 54 force the tape 12 to be bent into the pair of drive rollers 51.
（１－４．フレーム構造の変形）
　上述したように構成されたフレーム構造体１の三次元フレーム構造は、図１から図３に示すように、折曲部２３ａ～２３ｈが第１ジョイント部１４または第２ジョイント部１５により集約され、集約された集約箇所Ｆの全てを頂部（頂上部Ａまたは底面頂部Ｂ）とする四面体の三次元フレーム構造を構成している。そして、この三次元フレーム構造は変形することが可能である。なお、上述したように構成されたフレーム構造体１の「集約箇所Ｆ」は、機械的な固い結合でも緩い結合でもよい。 (1-4. Modification of frame structure)
In the three-dimensional frame structure of the frame structure 1 configured as described above, the bent portions 23a to 23h are aggregated by the first joint portion 14 or the second joint portion 15 as shown in FIGS. A tetrahedral three-dimensional frame structure having all the aggregated portions F as the top (the top A or the bottom B) is configured. The three-dimensional frame structure can be deformed. Note that the “aggregation point F” of the frame structure 1 configured as described above may be mechanically hard or loose.
　上述したように構成されたフレーム構造体１は、駆動ローラ５１が回転することによりテープ１２の繰り出しおよび繰り込みが可能であるため、繰り出しおよび繰り込みによりテープ１２を移動、第１ジョイント部１４および第２ジョイント部１５の位置を移動することにより、三次元フレーム構造を所定の形状に変形することができる。たとえば、直稜四面体の形状、垂心四面体の形状、当面四面体の形状等、様々な四面体の形状に形成することができる。 Since the frame structure 1 configured as described above can feed and retract the tape 12 by the rotation of the driving roller 51, the tape 12 is moved by the feeding and retracting, and the first joint portion 14 and the second joint portion 14 are moved. By moving the position of the joint portion 15, the three-dimensional frame structure can be transformed into a predetermined shape. For example, it can be formed in various tetrahedron shapes such as a shape of a straight ridge tetrahedron, a shape of a perpendicular tetrahedron, and a shape of a current tetrahedron.
　また、上述したように構成されたフレーム構造体１のテープ１２は、曲げ剛性に異方性があるので、長さ方向に沿って容易に折曲可能である一方、幅方向に沿って折り曲げるのが難しい。つまり、テープ１２を折り曲げまたは捻り曲げることにより、三次元フレーム構造を変形自在にすることができる。 Further, since the tape 12 of the frame structure 1 configured as described above has anisotropy in bending rigidity, the tape 12 can be easily bent along the length direction, while being bent along the width direction. Is difficult. That is, the three-dimensional frame structure can be made deformable by bending or twisting the tape 12.
　さらに、上述したように構成されたフレーム構造体１は、第２ジョイント部１５の数を増加することにより、四面体のみならず、四角錐の形状、五角錐の形状、六角錐の形状等の様々な角錐の形状にも形成することができる。さらに、立方体を含む、五面以上を有する任意の立体にも形成することができる。 Further, the frame structure 1 configured as described above increases not only the tetrahedron but also the shape of a quadrangular pyramid, the shape of a pentagonal pyramid, the shape of a hexagonal pyramid, etc. by increasing the number of the second joint portions 15. It can also be formed in various pyramid shapes. Furthermore, it can be formed in any solid having five or more faces including a cube.
　次に、図１から図３、図６および図７を参照して、第１実施形態に係るフレーム構造体１の組立、収納および展開方法について説明する。 Next, with reference to FIG. 1 to FIG. 3, FIG. 6, and FIG. 7, a method for assembling, storing, and deploying the frame structure 1 according to the first embodiment will be described.
（１－５．組立方法）
　はじめに、図１から図３を参照して、フレーム構造体１の組立方法について説明する。フレーム構造体１の組立方法は、まず、巻取部１６に巻き取られたテープ１２を図３に示す繰り出し方向Ｃに繰り出して、稜線部２２ａから駆動ローラ５１ａに巻回することによって折曲部２３ａを形成し、折曲部２３ａから底辺部２４ａ、底辺部２４ａから駆動ローラ５１ｂに巻回することによって折曲部２３ｂを形成し、折曲部２３ｂから稜線部２２ｂ、稜線部２２ｂからガイドローラ４１ａに巻回することによって折曲部２３ｃを形成する。 (1-5. Assembly method)
First, an assembly method of the frame structure 1 will be described with reference to FIGS. 1 to 3. The frame structure 1 is assembled by first feeding the tape 12 wound around the winding portion 16 in the feeding direction C shown in FIG. 3 and winding the tape 12 around the drive roller 51a from the ridgeline portion 22a. 23a is formed, and the bent portion 23b is formed by winding the bent portion 23a around the bottom portion 24a and the bottom portion 24a around the driving roller 51b, and the bent portion 23b is formed with the ridge line portion 22b, and the ridge line portion 22b is guided with the guide roller. The bent portion 23c is formed by winding it around 41a.
　同様に、繰り出し方向Ｃに繰り出して、折曲部２３ｃから稜線部２２ｃ、稜線部２２ｃから駆動ローラ５１ｄに巻回することによって折曲部２３ｄを形成し、折曲部２３ｄから底辺部２４ｂ、底辺部２４ｂから駆動ローラ５１ｅに巻回することによって折曲部２３ｅを形成し、折曲部２３ｅから稜線部２２ｄ、稜線部２２ｄからガイドローラ４１ｂに巻回することによって折曲部２３ｆを形成する。 Similarly, a bent portion 23d is formed by winding in the extending direction C and winding from the bent portion 23c to the ridge line portion 22c and from the ridge line portion 22c to the drive roller 51d, and from the bent portion 23d to the bottom side portion 24b, the bottom side The bent portion 23e is formed by winding the drive roller 51e from the portion 24b, and the bent portion 23f is formed by winding the ridge line portion 22d from the bent portion 23e and the guide roller 41b from the ridge line portion 22d.
　さらに、繰り出し方向Ｃに繰り出して、折曲部２３ｆから稜線部２２ｅ、稜線部２２ｅから駆動ローラ５１ｇに巻回することによって折曲部２３ｇを形成し、折曲部２３ｇから底辺部２４ｃ、底辺部２４ｃから駆動ローラ５１ｈに巻回することによって折曲部２３ｈを形成し、折曲部２３ｈから稜線部２２ｆを形成し、基端部２５が繰り出された巻取部１６に先端部２１を係合することにより四面体の三次元フレーム構造を形成する。 Further, the bent portion 23g is formed by winding in the feeding direction C and winding from the bent portion 23f to the ridge line portion 22e and from the ridge line portion 22e to the drive roller 51g, and from the bent portion 23g to the bottom portion 24c, the bottom portion 24c is wound around the driving roller 51h to form a bent portion 23h, a ridge line portion 22f is formed from the bent portion 23h, and the distal end portion 21 is engaged with the winding portion 16 from which the base end portion 25 is extended. By doing so, a tetrahedral three-dimensional frame structure is formed.
　図１および図２に示すように、折曲部２３ｃはガイドローラ４１ａ、折曲部２３ｆはガイドローラ４１ｂの周面上にテープ１２を巻回することにより形成し、ガイドローラ４１が回動することによりテープ１２がガイドローラ４１の外周上を摺動する。 As shown in FIGS. 1 and 2, the bent portion 23c is formed by winding the tape 12 around the guide roller 41a and the bent portion 23f is wound on the peripheral surface of the guide roller 41b, and the guide roller 41 rotates. As a result, the tape 12 slides on the outer periphery of the guide roller 41.
　また、折曲部２３ａ、２３ｂ、２３ｄ、２３ｅ、２３ｇ、２３ｈは、一対の駆動ローラ５１の周面上にテープ１２を巻回することにより形成し、一対の駆動ローラ５１が回動することによりテープ１２が一対の駆動ローラ５１の外周上を摺動する。このため、巻取部１６からテープ１２の先端部２１を繰り出してガイドローラ４１や駆動ローラ５１に巻回することにより、容易に折曲部２３を形成しながら基端部２５を繰り出し続けて四面体の三次元フレーム構造を形成することができる。 The bent portions 23a, 23b, 23d, 23e, 23g, and 23h are formed by winding the tape 12 on the peripheral surfaces of the pair of drive rollers 51, and the pair of drive rollers 51 is rotated. The tape 12 slides on the outer periphery of the pair of drive rollers 51. For this reason, the distal end portion 21 of the tape 12 is unwound from the winding portion 16 and wound around the guide roller 41 or the driving roller 51, so that the proximal end portion 25 is continuously unwound while the bent portion 23 is easily formed. A three-dimensional frame structure of the body can be formed.
　そして、テープ１２が２重に配置されている稜線部２２ａと稜線部２２ｆ、稜線部２２ｂと稜線部２２ｃ、稜線部２２ｄと稜線部２２ｅをそれぞれ結束部材１３により結束して互いの稜線部２２を平行に成型する。 And the ridgeline part 22a and the ridgeline part 22f by which the tape 12 is arrange | positioned doubly, the ridgeline part 22b and the ridgeline part 22c, and the ridgeline part 22d and the ridgeline part 22e are respectively bound by the binding member 13, and each ridgeline part 22 is attached. Mold in parallel.
（１－６．収納方法）
　次に、図１から図３、図６および図７を参照して、第１実施形態に係るフレーム構造体１の収納方法について説明する。フレーム構造体１の収納方法の一例では、図６に示すように、底辺部２４ａ～２４ｃの両端から略等距離にある点を折り曲げ、三次元フレーム構造を縦方向（矢印Ｅ方向）に引き伸ばすことにより、四面体の三次元フレーム構造を縦長状に折り畳む。 (1-6. Storage method)
Next, a method for housing the frame structure 1 according to the first embodiment will be described with reference to FIGS. 1 to 3, 6, and 7. In an example of the storage method of the frame structure 1, as shown in FIG. 6, the points that are approximately equidistant from the both ends of the bases 24a to 24c are bent, and the three-dimensional frame structure is stretched in the vertical direction (arrow E direction). Thus, the three-dimensional frame structure of the tetrahedron is folded vertically.
　上述したように、テープ１２の曲げ剛性には異方性があるため、図１に示す底辺部２４を折り曲げることができ、また、ガイドローラ４１や一対の駆動ローラ５１の周面上をテープ１２が摺動するため、四面体の三次元フレーム構造を縦長状に変形し、筒状容器に収納することができる。 As described above, since the bending rigidity of the tape 12 has anisotropy, the base 24 shown in FIG. 1 can be bent, and the circumferential surface of the guide roller 41 and the pair of driving rollers 51 is on the tape 12. Therefore, the tetrahedral three-dimensional frame structure can be transformed into a vertically long shape and stored in a cylindrical container.
　また、フレーム構造体１の収納方法の他例では、図７に示すように、底辺部２４ａ～２４ｃの長さを短くして三次元フレーム構造を縦方向（矢印Ｅ方向）に引き伸ばすことにより、四面体の三次元フレーム構造を縦長状の三次元フレーム構造に変形する。 Further, in another example of the method of storing the frame structure 1, as shown in FIG. 7, by shortening the length of the bottom portions 24a to 24c and extending the three-dimensional frame structure in the vertical direction (arrow E direction), The tetrahedral three-dimensional frame structure is transformed into a vertically long three-dimensional frame structure.
　さらに、フレーム構造体１の収納方法の他例では、上述した巻取部１６の巻取ボタン（図示省略）を押圧することによりテープ１２を巻き取り、四面体の三次元フレーム構造を巻取部１６の内部に収納する。この収納方法の場合、上記した展開方法の場合と逆の手順に従って収納できる。 Furthermore, in another example of the method for storing the frame structure 1, the tape 12 is wound up by pressing the winding button (not shown) of the winding unit 16 described above, and the tetrahedral three-dimensional frame structure is wound up into the winding unit. 16 is housed inside. In the case of this storage method, it can be stored according to the reverse procedure of the above-described deployment method.
　なお、結束部材１３を外し、ガイドローラ４１や一対の駆動ローラ５１の周面上に巻回されたテープ１２を解いてから、一気にテープ１２を巻き取ることも可能である。 It is also possible to remove the binding member 13 and unwind the tape 12 wound on the peripheral surfaces of the guide roller 41 and the pair of drive rollers 51, and then wind the tape 12 at once.
