本発明は、ラゲッジボードに関する。   The present invention relates to a luggage board.

従来から、インテグラルヒンジ部が形成されたラゲッジボードが公知である（特許文献１参照）。この特許文献１に記載されたラゲッジボードは、第１ボードと第２ボードとを薄肉部で連結することで構成され、この薄肉部がインテグラルヒンジ部に形成されている。そして、インテグラルヒンジ部に直交する方向に延在すると共にインテグラルヒンジ部を跨ぐようにばね部材が配設される。   Conventionally, a luggage board in which an integral hinge portion is formed is known (see Patent Document 1). The luggage board described in Patent Document 1 is configured by connecting a first board and a second board with a thin part, and the thin part is formed in an integral hinge part. And a spring member is arrange | positioned so that it may extend in the direction orthogonal to an integral hinge part, and straddle an integral hinge part.

特開２０１２−２０１３１４号公報JP 2012-201314 A

前記特許文献１においては、ばね部材の一端のリングが第１ボードにリベットで保持され、ばね部材の他端のリングが第２ボードにリベットで保持される。このため、ラゲッジボードの長期間の使用によってリベットの保持力が低下した場合、第１ボードおよび第２ボードを折り畳んだときに、ばね部材の一端のリングおよび他端のリングがボードの面と擦れて異音が発生するおそれがある。   In Patent Document 1, the ring at one end of the spring member is held on the first board by rivets, and the ring at the other end of the spring member is held by rivets on the second board. For this reason, when the holding power of the rivet is reduced by using the luggage board for a long time, when the first board and the second board are folded, the ring at one end and the ring at the other end of the spring member rub against the board surface. May cause abnormal noise.

そこで、本発明は、インテグラルヒンジ部を跨いでバネ部材が配設されたラゲッジボードについて、折り畳んだときに異音の発生を抑制することができるラゲッジボードを提供することを目的とする。   Therefore, an object of the present invention is to provide a luggage board that can suppress the generation of abnormal noise when folded about a luggage board in which a spring member is disposed across an integral hinge portion.

本発明に係るラゲッジボードは、第１のボードと、前記第１のボードにヒンジを介して折り曲げ可能に連結された第２のボードと、一方の端部が前記第１のボードにリベットを介して固定され、他方の端部が前記第２のボードにリベットを介して固定されたばね部材と、を備えている。前記ばね部材の端部は、平面視で、直線状に延びる直線部と、前記直線部の先端から巻回しながら円環状に延びる弾性体である円環部と、から一体に形成されている。前記円環部は、無負荷状態において途中部分から螺旋状に斜め上方に向けて徐々に高くなる高さ変化部を有する。前記リベットで前記ばね部材の端部がボードに固定されたときには、前記高さ変化部はリベットでボードに押し付けられることによって押し潰され、高さ方向に復元しようとする付勢力を保持している。   A luggage board according to the present invention includes a first board, a second board that is foldably connected to the first board via a hinge, and one end portion that is connected to the first board via a rivet. And a spring member fixed at the other end to the second board via a rivet. The end portion of the spring member is integrally formed from a straight portion that extends linearly in a plan view and an annular portion that is an elastic body that extends in an annular shape while being wound from the tip of the straight portion. The annular portion has a height changing portion that gradually increases upward in a spiral manner from an intermediate portion in an unloaded state. When the end of the spring member is fixed to the board with the rivet, the height changing portion is crushed by being pressed against the board with the rivet, and holds the urging force to restore in the height direction. .

本発明では、リベットでばね部材の端部がボードに固定されたときには、高さ変化部はリベットでボードに押し付けられることによって押し潰され、端部は、高さ変化部が高さ方向に復元しようとする付勢力を保持している。このため、リベットのボードに対する保持力が低下し、リベットの頭部とボードの面との距離が多少大きくなっても、ばね部材の高さ変化部の付勢力によってばね部材の端部がリベットに確実に保持される。従って、第１のボードおよび第２のボードを折り畳んだときに、ばね部材の端部がボードの面と擦れて発生する異音を抑制することができる。   In the present invention, when the end of the spring member is fixed to the board with the rivet, the height changing portion is crushed by being pressed against the board with the rivet, and the height changing portion is restored in the height direction at the end. Hold the urging power to try. For this reason, even if the holding force of the rivet against the board is reduced and the distance between the head of the rivet and the surface of the board is slightly increased, the end of the spring member becomes the rivet by the biasing force of the height changing portion of the spring member. Holds securely. Therefore, when the first board and the second board are folded, it is possible to suppress abnormal noise generated by rubbing the end of the spring member with the surface of the board.

A back panel 10 is disposed behind the storage box 7.

図１〜４に示すように、ラゲッジボード９は樹脂で形成されている。具体的には、車両前方側に配置した第１のボード１１と、第１のボード１１にインテグラルヒンジ部１３（ヒンジ）を介して折り曲げ可能に連結された第２のボード１２と、これらの第１のボード１１および第２のボード１２の境界部に形成されたインテグラルヒンジ部１３（ヒンジ）と、インテグラルヒンジ部１３を跨いで配設されるばね部材１５と、第２のボード１２にインテグラルヒンジ部１３を介して折り曲げ可能に連結された第３のボード１７と、を備えている。なお、第２のボード１２では、裏面側に取手部１９が設けられている。   As shown in FIGS. 1-4, the luggage board 9 is formed with resin. Specifically, a first board 11 disposed on the front side of the vehicle, a second board 12 connected to the first board 11 via an integral hinge portion 13 (hinge) so as to be bent, and these An integral hinge part 13 (hinge) formed at the boundary between the first board 11 and the second board 12, a spring member 15 disposed across the integral hinge part 13, and the second board 12 And a third board 17 connected via an integral hinge part 13 so as to be foldable. In the second board 12, a handle 19 is provided on the back side.

第１のボード１１は、右側部２１および左側部２３に分割されている。図１，２に示すように、乗員が着席できるようにシートバック２５を立てた状態では、第１のボード１１の右側部２１は、第２のボード１２に対して上側に折れ曲がり、ばね部材１５が弾性変形している。ばね部材１５が弾性変形によって付勢されているため、第１のボード１１の右側部２１はシートバック２５の背面に当接している。   The first board 11 is divided into a right side portion 21 and a left side portion 23. As shown in FIGS. 1 and 2, in a state where the seat back 25 is stood so that an occupant can sit, the right side portion 21 of the first board 11 is bent upward with respect to the second board 12, and the spring member 15. Is elastically deformed. Since the spring member 15 is biased by elastic deformation, the right side portion 21 of the first board 11 is in contact with the back surface of the seat back 25.

図１，３に示すように、シートバック２５を前側に倒した状態では、第１のボード１１の左側部２３は、第２のボード１２と面一に配置され、ばね部材１５が元の状態に復元している。   As shown in FIGS. 1 and 3, in a state where the seat back 25 is tilted forward, the left side portion 23 of the first board 11 is disposed flush with the second board 12, and the spring member 15 is in the original state.

図５に示すように、ラゲッジボード９の構成は、表側に配置された板状の表側部材２７と、裏側に配置された板状の裏側部材２９と、これらの表側部材２７および裏側部材２９の間に配置された中間部材３１と、から一体に形成されている。これらの表側部材２７、裏側部材２９および中間部材３１は、ともに樹脂からなる。中間部材３１には、複数の凹凸部分３３が形成されている。中間部材３１の表面には表側部材２７が接合され、中間部材３１の裏面には裏側部材２９が接合されている。   As shown in FIG. 5, the structure of the luggage board 9 includes a plate-like front side member 27 arranged on the front side, a plate-like back side member 29 arranged on the back side, and the front side member 27 and the back side member 29. The intermediate member 31 is formed integrally with the intermediate member 31 disposed therebetween. The front side member 27, the back side member 29, and the intermediate member 31 are all made of resin. A plurality of concave and convex portions 33 are formed on the intermediate member 31. A front side member 27 is joined to the surface of the intermediate member 31, and a back side member 29 is joined to the back surface of the intermediate member 31.

図６に示すように、ばね収容凹部Ｓには、ばね部材１５が収容されている。ばね収容凹部Ｓは、第１のボード１１の端部４５に形成された傾斜面３５と第２のボード１２に形成された傾斜面３７とで構成される。ばね部材１５は、図６，７に示すように、螺旋状に巻回されたばね本体部４１と、ばね本体部４１の両端から延びる一対の脚部４３と、脚部４３の先端に設けられた端部４５とから一体に形成されている。   As shown in FIG. 6, the spring member 15 is accommodated in the spring accommodating recess S. The spring accommodating recess S includes an inclined surface 35 formed on the end 45 of the first board 11 and an inclined surface 37 formed on the second board 12. As shown in FIGS. 6 and 7, the spring member 15 is provided at the spring body 41 wound spirally, the pair of legs 43 extending from both ends of the spring body 41, and the tips of the legs 43. It is formed integrally with the end portion 45.

図８〜図１０に示すように、ばね部材１５の端部４５は、平面視で、直線状に延びる直線部５１と、直線部５１の先端から巻回しながら円環状に延びる弾性体である円環部５３と、から一体に形成されている。円環部５３は、平坦部５５と高さ変化部５７と直交部５９とから構成される。   As shown in FIGS. 8 to 10, the end portion 45 of the spring member 15 has a straight portion 51 that extends linearly in a plan view, and a circle that is an elastic body that extends in an annular shape while winding from the tip of the straight portion 51. The ring portion 53 is integrally formed. The annular portion 53 includes a flat portion 55, a height changing portion 57, and an orthogonal portion 59.

平坦部５５は、直線部５１の先端から延びて形成されている。無負荷状態において、直線部５１の高さと同等に形成されて平面視が円弧状に形成されている。具体的には、図１０に示すように、円環部５３の径方向中心部Ｏを中心とする１／４円の範囲が平坦部５５に設定されている。   The flat portion 55 is formed extending from the tip of the straight portion 51. In the no-load state, it is formed to be equal to the height of the straight portion 51 and is formed in an arc shape in plan view. Specifically, as shown in FIG. 10, a range of a quarter circle centering on the radial center O of the annular portion 53 is set in the flat portion 55.

高さ変化部５７は、図８の実線で示すように、無負荷状態において平坦部５５の先端から螺旋状に斜め上方に向けて徐々に高くなる。なお、図８の二点鎖線は、高さ変化部５７がなく直交部５９と脚部４３の先端との高さが同一に設定されている。これらの実線と二点鎖線との高さの差異はｈに設定されている。また、図１０に示すように、円環部５３の径方向中心部Ｏを中心とする半円の範囲が高さ変化部５７に設定されている。   As shown by the solid line in FIG. 8, the height changing portion 57 gradually increases in a spiral shape from the tip of the flat portion 55 in the no-load state. The two-dot chain line in FIG. 8 does not have the height changing portion 57 and the heights of the orthogonal portion 59 and the tip of the leg portion 43 are set to be the same. The difference in height between the solid line and the two-dot chain line is set to h. Also, as shown in FIG. 10, a semicircular range centering on the radial center O of the annular portion 53 is set in the height changing portion 57.

直交部５９は、高さ変化部５７の先端から延在している。図１０に示すように、平面視において直線部５１と直交して直線状に延びている。   The orthogonal part 59 extends from the tip of the height changing part 57. As shown in FIG. 10, it extends in a straight line orthogonal to the straight line portion 51 in plan view.

ここで、平坦部５５と高さ変化部５７との境界部６１および直交部５９と高さ変化部５７との境界部６３は、円環部５３の径方向中心部Ｏを通る直線のうち、直線部５１に平行に延びる所定の直線が円環部５３と交差する交差部分である。換言すると、高さ変化部５７の一端は、平坦部５５側の交差部分であり、高さ変化部５７の他端は、直交部５９側の交差部分である。   Here, the boundary portion 61 between the flat portion 55 and the height changing portion 57 and the boundary portion 63 between the orthogonal portion 59 and the height changing portion 57 are among straight lines passing through the radial center O of the annular portion 53. A predetermined straight line extending in parallel with the straight line portion 51 is an intersection where the circular ring portion 53 intersects. In other words, one end of the height changing portion 57 is an intersecting portion on the flat portion 55 side, and the other end of the height changing portion 57 is an intersecting portion on the orthogonal portion 59 side.

次に、図１１〜図１５を用いて、ばね部材１５の端部４５を第１のボード１１にブラインドリベット７１（リベット）で締結する手順を説明する。   Next, a procedure for fastening the end portion 45 of the spring member 15 to the first board 11 with the blind rivet 71 (rivet) will be described with reference to FIGS.

前提として、図１１に示すように、凹凸部分３３は、横面８１と縦面８３とを有する。横面８１は裏側部材２９に接合されており、縦面８３は横面８１の端縁で屈曲して横面８１に直交して、図１１の上下方向に沿って延びる。裏側部材２９にはリベット孔８０Ａが形成され、横面８１にはリベット孔８０Ｂが形成されている。   As a premise, as shown in FIG. 11, the uneven portion 33 has a horizontal surface 81 and a vertical surface 83. The horizontal surface 81 is joined to the back member 29, and the vertical surface 83 is bent at the edge of the horizontal surface 81 and is orthogonal to the horizontal surface 81 and extends along the vertical direction of FIG. A rivet hole 80A is formed in the back member 29, and a rivet hole 80B is formed in the lateral surface 81.

図１２に示すように、ブラインドリベット７１は、マンドレル８５とリベット本体８７とによって構成されている。   As shown in FIG. 12, the blind rivet 71 includes a mandrel 85 and a rivet body 87.

マンドレル８５は、棒状に延在すると共に軸方向の途中に径寸法が局所的に小さくなる易破断部８９を有する軸部９１と、軸部９１の先端側に設けられ、リベット本体８７のマンドレル挿通孔９３よりも大きな径寸法に形成された頭部９５と、を有している。   The mandrel 85 extends in a rod shape and has a shaft portion 91 having an easily breakable portion 89 whose diameter is locally reduced in the middle of the axial direction, and a mandrel insertion portion of the rivet body 87. A head portion 95 having a diameter larger than that of the hole 93.

リベット本体８７は、径方向に広がる円盤状のフランジ９７と、フランジ９７から中心軸方向に延在する筒状のスリーブ９９と、から構成されている。また、フランジ９７およびスリーブ９９には、中心軸方向に沿って延在する円筒状のマンドレル挿通孔９３が形成されている。このマンドレル挿通孔９３には、マンドレル８５の軸部９１が挿入および保持される。なお、図１１に示すリベット孔８０Ａ，８０Ｂの孔径は、リベット本体８７のスリーブ９９の径寸法より大きく、かつ、フランジ９７の径寸法よりも小さく設定されている。   The rivet main body 87 includes a disk-shaped flange 97 extending in the radial direction and a cylindrical sleeve 99 extending from the flange 97 in the central axis direction. The flange 97 and the sleeve 99 are formed with a cylindrical mandrel insertion hole 93 extending along the central axis direction. The shaft portion 91 of the mandrel 85 is inserted and held in the mandrel insertion hole 93. The hole diameters of the rivet holes 80A and 80B shown in FIG. 11 are set larger than the diameter dimension of the sleeve 99 of the rivet body 87 and smaller than the diameter dimension of the flange 97.

以下に、ばね部材１５の端部４５を第１のボード１１にブラインドリベット７１で締結する作業手順を説明する。   Below, the work procedure which fastens the edge part 45 of the spring member 15 to the 1st board 11 with the blind rivet 71 is demonstrated.

まず、図１３に示すように、ばね部材１５の端部４５の円環部５３がリベット孔８０Ａ，８０Ｂを囲むようにばね部材１５を配置する。このとき、ばね部材１５の高さ変化部５７は弾性変形が始まる直前の段階であり、ばね部材１５の直線部５１と裏側部材２９の裏面との高さがｈになっている。   First, as shown in FIG. 13, the spring member 15 is disposed so that the annular portion 53 of the end portion 45 of the spring member 15 surrounds the rivet holes 80A and 80B. At this time, the height changing portion 57 of the spring member 15 is immediately before the elastic deformation starts, and the height between the straight portion 51 of the spring member 15 and the back surface of the back side member 29 is h.

次に、ブラインドリベット７１におけるリベット本体８７のスリーブ９９を、ばね部材１５の円環部５３の内周およびリベット孔８０Ａ，８０Ｂに挿入する。この状態でマンドレル８５を軸部側（図１３の上側）に引くと、頭部９５がリベット本体８７のスリーブ９９を引き裂いて分割片１０１が形成される。これらの分割片１０１は、径方向の外方に向けて花びら状に拡開し、分割片１０１の先端１０１ａは、中間部材３１の縦面８３に突き当たる。   Next, the sleeve 99 of the rivet main body 87 in the blind rivet 71 is inserted into the inner periphery of the annular portion 53 of the spring member 15 and the rivet holes 80A and 80B. In this state, when the mandrel 85 is pulled toward the shaft side (upper side in FIG. 13), the head 95 tears the sleeve 99 of the rivet body 87 and the split piece 101 is formed. These divided pieces 101 expand in the shape of petals toward the outside in the radial direction, and the leading ends 101a of the divided pieces 101 abut against the vertical surfaces 83 of the intermediate member 31.

図１４，１５に示すように、マンドレル８５を軸部側（図１４，１５の上側）に更に引き上げると、この分割片１０１の先端１０１ａは、拡開時において、中間部材３１の縦面８３を突き破って縦面８３の外方に大きく突き出る。このとき、マンドレル８５が易破断部８９で切断される。これにより、リベット本体８７を介してばね部材１５の端部４５が裏側部材２９の裏面に締結される。   As shown in FIGS. 14 and 15, when the mandrel 85 is further lifted to the shaft side (upper side of FIGS. 14 and 15), the tip 101 a of the divided piece 101 is formed so that the vertical surface 83 of the intermediate member 31 is not expanded. It pierces and protrudes greatly outside the vertical surface 83. At this time, the mandrel 85 is cut at the easily breakable portion 89. As a result, the end 45 of the spring member 15 is fastened to the back surface of the back member 29 via the rivet body 87.

このように、ブラインドリベット７１でばね部材１５の端部４５が第１のボード１１に固定されたときには、高さ変化部５７は押し潰され、高さ方向に復元しようとする付勢力を保持している。   As described above, when the end portion 45 of the spring member 15 is fixed to the first board 11 by the blind rivet 71, the height changing portion 57 is crushed and holds the urging force to restore in the height direction. ing.

以下に、本実施形態による作用効果を説明する。   Below, the effect by this embodiment is demonstrated.

（１）ラゲッジボード９は、第１のボード１１と、第１のボード１１にインテグラルヒンジ部１３（ヒンジ）を介して折り曲げ可能に連結された第２のボード１２と、一方の端部４５が第１のボード１１にブラインドリベット７１（リベット）を介して固定され、他方の端部４５が第２のボード１２にブラインドリベット７１（リベット）を介して固定されたばね部材１５と、を備える。ばね部材１５の端部４５は弾性体であり、端部４５は、平面視で、直線状に延びる直線部５１と、直線部５１の先端から巻回しながら円環状に延びる円環部５３と、から一体に形成されている。円環部５３は、無負荷状態において途中部分から螺旋状に斜め上方に向けて徐々に高くなる高さ変化部５７を有する。  (1) The luggage board 9 includes a first board 11, a second board 12 connected to the first board 11 via an integral hinge part 13 (hinge) so as to be bent, and one end part 45. Is fixed to the first board 11 via a blind rivet 71 (rivet), and the other end 45 is fixed to the second board 12 via a blind rivet 71 (rivet). The end portion 45 of the spring member 15 is an elastic body, and the end portion 45 includes a linear portion 51 that extends linearly in a plan view, an annular portion 53 that extends in an annular shape while being wound from the tip of the linear portion 51, and It is integrally formed from. The annular portion 53 has a height changing portion 57 that gradually increases upward in a spiral manner from an intermediate portion in an unloaded state.

ブラインドリベット７１でばね部材１５の端部４５がボードに固定されたときには、高さ変化部５７はブラインドリベット７１でボードに押し付けられることによって押し潰され、端部４５は、高さ変化部５７が高さ方向に復元しようとする付勢力を保持している。このため、ブラインドリベット７１のボードに対する保持力が低下し、ブラインドリベット７１の頭部７３とボードの面との距離が多少大きくなっても、ばね部材１５の高さ変化部５７の付勢力によってばね部材１５の端部４５がブラインドリベット７１に確実に保持される。従って、第１のボード１１および第２のボード１２を折り畳んだときに、ばね部材１５の端部４５がボードの面と擦れて発生する異音を抑制することができる。   When the end 45 of the spring member 15 is fixed to the board by the blind rivet 71, the height changing portion 57 is crushed by being pressed against the board by the blind rivet 71, and the end 45 is moved by the height changing portion 57. Holds the urging force to restore in the height direction. For this reason, even if the holding force with respect to the board of the blind rivet 71 is reduced and the distance between the head 73 of the blind rivet 71 and the surface of the board is slightly increased, the spring is applied by the biasing force of the height changing portion 57 of the spring member 15. The end 45 of the member 15 is securely held by the blind rivet 71. Therefore, when the first board 11 and the second board 12 are folded, it is possible to suppress abnormal noise generated by rubbing the end 45 of the spring member 15 with the surface of the board.

（２）円環部５３は、直線部５１の先端と高さ変化部５７との間に、無負荷状態において直線部５１の高さと同等に形成されて平面視が円弧状の平坦部５５を有する。  (2) The annular portion 53 is formed between the tip of the straight portion 51 and the height changing portion 57 in the same manner as the height of the straight portion 51 in a no-load state, and a flat portion 55 having a circular arc in plan view is formed. Have.

ばね部材１５の端部４５において直線部５１と平坦部５５とが平坦に形成されているため、これらの直線部５１および平坦部５５で第１および第２のボード１１，１２に当接する。従って、ばね部材１５の端部４５の根本部分が第１および第２のボード１１，１２の面に確実に当接して保持される。   Since the straight portion 51 and the flat portion 55 are formed flat at the end 45 of the spring member 15, the straight portion 51 and the flat portion 55 abut against the first and second boards 11 and 12. Therefore, the root portion of the end portion 45 of the spring member 15 is securely held in contact with the surfaces of the first and second boards 11 and 12.

（３）円環部５３における平坦部５５と高さ変化部５７との境界部６１は、円環部５３の径方向中心部Ｏを通る直線のうち、直線部５１に平行に延びる所定の直線が円環部５３と交差する部分である。  (3) The boundary portion 61 between the flat portion 55 and the height changing portion 57 in the annular portion 53 is a predetermined straight line extending in parallel with the straight portion 51 among straight lines passing through the radial center portion O of the annular portion 53. Is a portion that intersects with the annular portion 53.

円環部５３における直線部５１側の半分は、第１のボード１１または第２のボード１２に保持され、円環部５３における直線部５１から離れた反対側の半分は、弾性変形する高さ変化部５７である。このように、円環部５３の直線部５１側の半分と直線部５１側の反対側の半分とでバランスよく、ばね部材１５の端部４５が第１および第２のボード１１，１２の面に確実に当接して保持される。   The half of the annular portion 53 on the straight portion 51 side is held by the first board 11 or the second board 12, and the opposite half of the annular portion 53 away from the straight portion 51 is elastically deformed. It is a change part 57. In this way, the half of the annular portion 53 on the straight portion 51 side and the half on the opposite side of the straight portion 51 side are well balanced, and the end portion 45 of the spring member 15 is the surface of the first and second boards 11 and 12. Are held in contact with each other.

（４）円環部５３は、平面視において直線部５１と直交して直線状に延びる直交部５９が高さ変化部５７の先端から延在している。  (4) In the annular portion 53, an orthogonal portion 59 that extends in a straight line perpendicular to the linear portion 51 in a plan view extends from the tip of the height changing portion 57.

このように、直交部５９は直線部５１と直交して直線状に延びているため、直交部５９の全長が第１のボード１１または第２のボード１２に均等に当たる。   Thus, since the orthogonal part 59 extends in a straight line perpendicular to the straight part 51, the entire length of the orthogonal part 59 equally hits the first board 11 or the second board 12.

なお、本発明は、前述した実施形態に限定されない。   In addition, this invention is not limited to embodiment mentioned above.

例えば、本実施形態に係るラゲッジボード９は、表側部材２７、裏側部材２９および中間部材３１から構成されている。しかし、表側部材２７の表側や裏側部材２９の裏側に、不織布等の表皮材を配設してもよい。この場合、表皮材の上からばね部材１５の端部４５がブラインドリベット７１を介して固定される。   For example, the luggage board 9 according to this embodiment includes a front side member 27, a back side member 29, and an intermediate member 31. However, a skin material such as a non-woven fabric may be provided on the front side of the front side member 27 and the back side of the back side member 29. In this case, the end 45 of the spring member 15 is fixed via the blind rivet 71 from above the skin material.
