特公平6-43069号公報Japanese Patent Publication No. 6-43069

ヒンジ部に補強片を用いても、薄肉状のヒンジ部の延設方向と直交する方向の力が加わるような、例えば棚板に用いられる成形構造体においては、従来の構成のヒンジ部では強度不足が生じることがあった。 Even if reinforcing pieces are used in the hinge section, in molded structures used for shelves, for example, where a force is applied in a direction perpendicular to the extension direction of the thin-walled hinge section, the strength of the hinge section of the conventional configuration may be insufficient.

本発明は、取付用ブラケット部が接続される薄肉状のヒンジ部の破損を低減させた成形構造体を提供することを目的とする。 The present invention aims to provide a molded structure that reduces damage to the thin-walled hinge portion to which the mounting bracket portion is connected.

本発明の成形構造体は、被係合部を備える構造体本体と、薄肉形成されるヒンジ部を介して前記構造体本体と一体的に形成されて、前記被係合部と係合可能に形成される係合部を備える取付用ブラケット部とで構成され、前記取付用ブラケット部は、当該取付用ブラケット部の先端近傍であって角部近傍に貫通孔を有し、前記係合部は、前記取付用ブラケット部の上面に凸状とされ、前記取付用ブラケット部の下面側に金型凸部によって形成される凹部を有することを特徴とする。また、本発明の成形構造体は、被係合部を備える構造体本体と、薄肉形成されるヒンジ部を介して前記構造体本体と一体的に形成されて、前記被係合部と係合可能に形成される係合部を備える取付用ブラケット部とで構成され、前記構造体本体は、物品が載置される載置面を備え、前記係合部は、前記取付用ブラケット部の上面に凸状とされ、前記取付用ブラケット部の下面側に金型凸部によって形成される凹部を有し、前記被係合部は、前記取付用ブラケット部を前記載置面側に折り畳んだ際に前記係合部と係合する位置に設けられることを特徴とすることもある。 The molded structure of the present invention is characterized in that it is composed of a structure main body having an engaged portion, and a mounting bracket part having an engaging portion formed integrally with the structure main body via a thin-walled hinge part and capable of engaging with the engaged portion , the mounting bracket part having a through hole near the tip and near the corner of the mounting bracket part, the engaging portion being convex on the upper surface of the mounting bracket part and having a recess formed by a mold convex part on the lower surface side of the mounting bracket part . The molded structure of the present invention is also characterized in that it is composed of a structure main body having an engaged portion, and a mounting bracket part having an engaging portion formed integrally with the structure main body via a thin-walled hinge part and capable of engaging with the engaged portion, the structure main body has a placement surface on which an article is placed, the engaging portion being convex on the upper surface of the mounting bracket part and having a recess formed by a mold convex part on the lower surface side of the mounting bracket part, and the engaged portion is provided at a position where it engages with the engaging portion when the mounting bracket part is folded toward the placement surface.

本発明によれば、高強度のヒンジ部を備える成形構造体を提供することができる。 The present invention provides a molded structure with a high-strength hinge portion.

(第1実施形態)
次に、本発明の第1実施形態を図に基づいて説明する。図1に示す棚板1は、ブロー成形により形成されて、図6の例で示すコインロッカー100の構造体としての棚板1とされる成形構造体である。棚板1は、構造体本体10と、4つの取付用ブラケット部30を有する。構造体本体10は略中空に形成され、外観は平面視略長矩形状の略平板状に形成される。構造体本体10の一方面は載置面10aとされる。棚板1のコインロッカー100への取付けは、載置面10aが上面となるよう取り付けられる。なお、以下の説明においては、図1の手前側を前、その反対側を後とし、前側から見て左手側を左、右手側を右とする。また、載置面10a側を上、載置面10aと反対側の下面10b側を下とする。
First Embodiment
Next, a first embodiment of the present invention will be described with reference to the drawings. The shelf board 1 shown in FIG. 1 is a molded structure formed by blow molding, and is used as the shelf board 1 as a structure of the coin locker 100 shown in the example of FIG. 6. The shelf board 1 has a structure body 10 and four mounting bracket parts 30. The structure body 10 is formed to be substantially hollow, and the appearance is formed to be a substantially flat plate with a substantially long rectangular shape in a plan view. One side of the structure body 10 is a mounting surface 10a. The shelf board 1 is attached to the coin locker 100 so that the mounting surface 10a is the upper surface. In the following description, the front side of FIG. 1 is the front, the opposite side is the rear, the left hand side when viewed from the front side is the left, and the right hand side is the right. The mounting surface 10a side is the top, and the lower surface 10b side opposite the mounting surface 10a is the bottom.

図2に示すように、構造体本体10の下面10bには、左右方向に延設される凹溝13が前後方向に複数形成される。凹溝13においては、載置面10aを形成する上面板と下面10bを形成する下面板とが溶着されている。凹溝13には、凹溝13の底部から盛り上がって形成される溝底突出部13aが形成される。溝底突出部13aは、載置面10aを形成する上面板と下面10bを形成する下面板とが溶着せず、下方に突出して形成される。凹溝13によって、構造体本体10の左右方向の曲げに対する剛性が高められる。そして、凹溝13が延設される方向(左右方向)と、後述するヒンジ部40及び係合部32(被係合部14b)が延設される方向(前後方向)とが直交する。これにより、載置面10aに物品が載置されて、構造体本体10に曲げ力が掛かっても、係合部32と被係合部14bの係合が外れたりヒンジ部40が破損したりすることを防止することができる。また、隣接する凹溝13同士の溝底突出部13aは、左右方向の位置をずらして設けられる。これにより、ブロー成形する際に、吹き込んだ空気が循環し易くすることができる。凹溝13は合計5本設けられる。また、構造体本体10の四隅の角部近傍の前後方向の縁部側面には、ブラケット配置部14が形成される。ブラケット配置部14には、取付用ブラケット部30が設けられる。4つの取付用ブラケット部30は、前後及び左右で対称に形成され、対角の取付用ブラケット部30は同一形状とされる(後述の貫通孔31の形状を除く)。 2, a plurality of grooves 13 extending in the left-right direction are formed in the lower surface 10b of the structure body 10 in the front-rear direction. In the grooves 13, the upper plate forming the mounting surface 10a and the lower plate forming the lower surface 10b are welded together. In the grooves 13, a groove bottom protrusion 13a is formed by rising from the bottom of the groove 13. The groove bottom protrusion 13a is formed by protruding downward without welding the upper plate forming the mounting surface 10a and the lower plate forming the lower surface 10b. The grooves 13 increase the rigidity of the structure body 10 against bending in the left-right direction. The direction in which the grooves 13 extend (left-right direction) is perpendicular to the direction in which the hinge portion 40 and the engaging portion 32 (engaged portion 14b) described later are extended (front-rear direction). This prevents the engagement between the engaging portion 32 and the engaged portion 14b from coming loose and the hinge portion 40 from being damaged, even if an object is placed on the placement surface 10a and a bending force is applied to the structure body 10. The groove bottom protrusions 13a of adjacent grooves 13 are offset in the left-right direction. This allows the air blown in to circulate easily during blow molding. A total of five grooves 13 are provided. In addition, bracket placement sections 14 are formed on the side of the edge in the front-rear direction near the four corners of the structure body 10. The bracket placement section 14 is provided with a mounting bracket section 30. The four mounting bracket sections 30 are formed symmetrically in the front-rear and left-right directions, and the diagonal mounting bracket sections 30 have the same shape (except for the shape of the through holes 31 described below).

図3(a),(b)は、右前側に配置される取付用ブラケット部30を拡大して示す斜視図及び平面図である。取付用ブラケット部30は、上述の通り、他の3つの取付用ブラケット部30と対称・同一であるため、図3に示す右前側の取付用ブラケット部30について説明し、他の3つの取付用ブラケット部30についての詳細な説明を省略する。 Figures 3(a) and (b) are an enlarged perspective view and a plan view of the mounting bracket part 30 located on the right front side. As described above, the mounting bracket part 30 is symmetrical and identical to the other three mounting bracket parts 30, so only the mounting bracket part 30 on the right front side shown in Figure 3 will be described, and detailed descriptions of the other three mounting bracket parts 30 will be omitted.

取付用ブラケット部30は、平面視略L字状の平板状であって、中実に形成され、平面視略L字状の内角側が前後の取付用ブラケット部30で対向するように配置される。取付用ブラケット部30は、薄肉形成されるヒンジ部40を介して構造体本体10と一体的に形成される。具体的には、取付用ブラケット部30は、取付用ブラケット部30の基部38(L字の下水平線部分に相当する部分)がヒンジ部40を介して構造体本体10のブラケット配置部14と接続する。従って、ヒンジ部40は、構造体本体10の前後方向に沿って形成される。取付用ブラケット部30の基部38には、係合部32が設けられる。係合部32は、載置面10a側に突出して凸状に形成され、構造体本体10の前後方向に長尺状に設けられる。また、取付用ブラケット部30の延設部39(L字の垂直線に相当する部分)の先端部近傍には、ネジ等により相手部材に取り付けるための貫通孔31が設けられる。 The mounting bracket portion 30 is a flat plate having an approximately L-shape in plan view, is solid, and is arranged so that the inner corners of the approximately L-shape in plan view face each other at the front and rear mounting bracket portions 30. The mounting bracket portion 30 is integrally formed with the structure body 10 via a hinge portion 40 formed with a thin wall. Specifically, the base portion 38 (the portion corresponding to the lower horizontal line of the L-shape) of the mounting bracket portion 30 is connected to the bracket arrangement portion 14 of the structure body 10 via the hinge portion 40. Therefore, the hinge portion 40 is formed along the front-rear direction of the structure body 10. The base portion 38 of the mounting bracket portion 30 is provided with an engagement portion 32. The engagement portion 32 is formed in a convex shape protruding toward the mounting surface 10a side and is provided in an elongated shape in the front-rear direction of the structure body 10. In addition, near the tip of the extension 39 (the part corresponding to the vertical line of the L-shape) of the mounting bracket part 30, a through hole 31 is provided for mounting to a mating member with a screw or the like.

図3(a),(b)と、図5にも示されるように、係合部32には、上面に係合部平坦面32aが形成される。係合部32のヒンジ部40側には、係合部平坦面32aと垂直な係合部垂直面32bが形成される。係合部32の外側側面は、取付用ブラケット部30の上面35に向けて下るように傾斜する係合部傾斜面32c(係合面)が形成される。また、取付用ブラケット部30の基部38の縁部近傍は、ヒンジ部40に向けて下るように傾斜してヒンジ部40と接続する係合部接続面33が形成される。また、係合部32の下面側(下面36側)は、凹状の凹部32dが形成される。凹部32dは、棚板1を成形する図示しないブロー成形用の金型の凸部により形成されるものであり、この金型の凸部により、係合部32を形成するキャビティに樹脂材料を押し付けるようにして成形することができる。このようにして、係合部32(特に係合面とされる係合部傾斜面32c)を精度よくブロー成形することができる。なお、凹部32dを形成する金型の凸部が無い場合には、取付用ブラケット部30全体を形成するための樹脂材料がキャビティ内に不足する場合があり、そうすると取付用ブラケット部30に中空部が形成されてしまったり、係合部32(特に係合部傾斜面32c)がキャビティの面に沿って形成されず、よって所望する精度が得られなかったりすることがある。 3(a) and (b) and also as shown in FIG. 5, the engagement portion 32 has an engagement portion flat surface 32a formed on the upper surface. The engagement portion 32 has an engagement portion vertical surface 32b formed on the hinge portion 40 side, which is perpendicular to the engagement portion flat surface 32a. The outer side surface of the engagement portion 32 has an engagement portion inclined surface 32c (engagement surface) that slopes downward toward the upper surface 35 of the mounting bracket portion 30. In addition, the engagement portion connection surface 33 that slopes downward toward the hinge portion 40 and connects to the hinge portion 40 is formed near the edge of the base 38 of the mounting bracket portion 30. In addition, a concave recess 32d is formed on the lower surface side (lower surface 36 side) of the engagement portion 32. The recess 32d is formed by the convex portion of the blow molding die (not shown) that molds the shelf board 1, and the convex portion of this die can be used to mold the engagement portion 32 by pressing the resin material into the cavity that forms the engagement portion 32. In this way, the engagement portion 32 (particularly the engagement portion inclined surface 32c, which is the engagement surface) can be blow molded with high precision. If the mold does not have a protruding portion for forming the recess 32d, there may not be enough resin material in the cavity to form the entire mounting bracket portion 30. This may result in a hollow portion being formed in the mounting bracket portion 30, or the engagement portion 32 (particularly the engagement portion inclined surface 32c) not being formed along the surface of the cavity, and therefore the desired precision may not be obtained.

ブラケット配置部14は、載置面10aと接続され載置面10aに略垂直な側面14aと、被係合部14bと、被係合部接続面14cと、下面部14dとを有する。被係合部14bは、取付用ブラケット部30の係合部32と係合可能に形成される。具体的には、凸状の係合部32と凹凸係合可能なように、側面14aから凹状に前後方向に長い略長矩形に形成される。 The bracket arrangement section 14 has a side surface 14a that is connected to the mounting surface 10a and is approximately perpendicular to the mounting surface 10a, an engaged section 14b, an engaged section connection surface 14c, and a bottom surface 14d. The engaged section 14b is formed so as to be able to engage with the engaging section 32 of the mounting bracket section 30. Specifically, it is formed in a generally elongated rectangle that is concave from the side surface 14a and long in the front-to-rear direction so as to be able to engage with the convex engaging section 32.

凹状の被係合部14b内の上側面は、側面14aにおける、載置面10aからの垂直面から下るように傾斜する被係合部傾斜面14b1(被係合面)が形成される。被係合部14bの底部は平坦な底面14b2とされる。底面14b2は、上端で被係合部傾斜面14b1と接続し、下端では底面14b2から略垂直壁状に形成される被係合部垂直面14b3が形成される。被係合部垂直面14b3は、ヒンジ部40に向けて下るように傾斜する被係合部接続面14cと接続する。被係合部接続面14cの下面は水平面とされて、垂直な下面部14dと接続する。 The upper side surface of the concave engaged portion 14b forms an engaged portion inclined surface 14b1 (engaged surface) that slopes downward from the vertical surface from the placement surface 10a on the side surface 14a. The bottom of the engaged portion 14b is a flat bottom surface 14b2. The bottom surface 14b2 connects to the engaged portion inclined surface 14b1 at the upper end, and forms an engaged portion vertical surface 14b3 that is formed from the bottom surface 14b2 in a substantially vertical wall shape at the lower end. The engaged portion vertical surface 14b3 connects to the engaged portion connection surface 14c that slopes downward toward the hinge portion 40. The lower surface of the engaged portion connection surface 14c is a horizontal plane that connects to the vertical lower surface portion 14d.

棚板1の取付けは、図4に示すように、取付用ブラケット部30を載置面10a側(上方向側)にヒンジ部40で折り畳んで行う。このとき、係合部32と被係合部14bは凹凸係合する。係合部32と被係合部14bが係合すると、図5に示すように、係合部傾斜面32cは、被係合部傾斜面14b1と当接又は所定の間隔を有してし、係合当接部50が形成される。係合当接部50は、取付用ブラケット部30を折り畳んで棚板1を取り付けた際に係合部傾斜面32cと被係合部傾斜面14b1(係合面と被係合面)とが当接してもよいし、係合部傾斜面32cと被係合部傾斜面14b1(係合面と被係合面)との間に隙間が形成される場合であっても、載置面10aに荷物等の物品が載置されて構造体本体10に下方向の荷重が掛かった場合に係合部傾斜面32cと被係合部傾斜面14b1(係合面と被係合面)が当接するように形成してもよい。なお、係合部平坦面32aと底面14b2及び側面14aと上面35の対応する部分とは、近接又は接触する程度に当接させることができる。そして、係合部垂直面32bは、被係合部垂直面14b3と対向し、被係合部垂直面14b3との間に隙間を有する。同様に、係合部接続面33は、被係合部接続面14cと対向し、被係合部接続面14cとの間に隙間を有する。 As shown in Figure 4, the shelf board 1 is attached by folding the mounting bracket part 30 toward the mounting surface 10a (upward) at the hinge part 40. At this time, the engaging part 32 and the engaged part 14b engage with each other in a concave-convex manner. When the engaging part 32 and the engaged part 14b engage with each other, as shown in Figure 5, the engaging part inclined surface 32c abuts or has a predetermined distance from the engaged part inclined surface 14b1, and an engaging abutment part 50 is formed. The engaging abutment portion 50 may be formed so that the engaging portion inclined surface 32c and the engaged portion inclined surface 14b1 (engaging surface and engaged surface) come into contact with each other when the mounting bracket portion 30 is folded and the shelf board 1 is attached, or may be formed so that the engaging portion inclined surface 32c and the engaged portion inclined surface 14b1 (engaging surface and engaged surface) come into contact with each other when an article such as luggage is placed on the placement surface 10a and a downward load is applied to the structure body 10. The engaging portion flat surface 32a and the bottom surface 14b2, and the corresponding parts of the side surface 14a and the upper surface 35 can come into contact with each other to the extent that they are close to each other or in contact with each other. The engaging portion vertical surface 32b faces the engaged portion vertical surface 14b3 and has a gap between it and the engaged portion vertical surface 14b3. Similarly, the engaging portion connection surface 33 faces the engaged portion connection surface 14c, and there is a gap between the engaged portion connection surface 14c.

棚板1は、このようにして取り付けられることにより、載置面10aに荷物等の物品が載置される際に、係合当接部50(特に、係合部傾斜面32cと被係合部傾斜面14b1(係合面と被係合面)の当接)により構造体本体10が支持される。従って、ヒンジ部40に、ヒンジ部40の延設方向と垂直な方向の荷重(本実施形態においては、前後方向に延設されるヒンジ部40に対して上下方向の荷重)が掛かり難くなるので、ヒンジ部40の破損を低減し、棚板1の耐久性を向上させることができる。 By attaching the shelf 1 in this manner, when an item such as luggage is placed on the placement surface 10a, the structure body 10 is supported by the engaging abutment portion 50 (particularly the abutment between the engaging portion inclined surface 32c and the engaged portion inclined surface 14b1 (the engaging surface and the engaged surface)). This makes it difficult for the hinge portion 40 to receive a load perpendicular to the extension direction of the hinge portion 40 (in this embodiment, a load in the vertical direction relative to the hinge portion 40 that extends in the front-to-rear direction), thereby reducing damage to the hinge portion 40 and improving the durability of the shelf 1.

また、互いに当接する係合部傾斜面32cと被係合部傾斜面14b1が傾斜しているので、構造体本体10が下方向の荷重を受けると、ヒンジ部40には構造体本体10の左右方向内方向の力が掛かり、垂直方向の力のみが掛かることがないので、より一層のヒンジ部40の破損の低減を実現することができる。 In addition, because the engaging portion inclined surface 32c and the engaged portion inclined surface 14b1 that abut against each other are inclined, when the structure body 10 receives a downward load, the hinge portion 40 is subjected to a force in the left-right inward direction of the structure body 10, and is not subjected to only vertical forces, which further reduces damage to the hinge portion 40.

さらにまた、取付用ブラケット部30の下面36と、取付の相手の構造部材とは当接するが、取付用ブラケット部30は上側に折り畳んで取り付けられるので、荷重が掛かった場合であっても、取付用ブラケット部30の下面36と相手構造部材との間に隙間が生じ難い。 Furthermore, although the underside 36 of the mounting bracket portion 30 comes into contact with the structural member to which it is attached, because the mounting bracket portion 30 is folded upward when attached, a gap is unlikely to form between the underside 36 of the mounting bracket portion 30 and the structural member to which it is attached, even when a load is applied.

また、棚板1は、構造体本体10と取付用ブラケット部30を一体としてブロー成形により形成することができる。 The shelf board 1 can also be formed by blow molding the structural body 10 and the mounting bracket portion 30 as a single unit.

なお、係合部傾斜面32c及び被係合部傾斜面14b1は、その傾斜する角度を任意の角度で形成することができ、例えば直角に形成することもできる。具体的には、図5に示すように、係合部傾斜面32c及び被係合部傾斜面14b1が水平線LVに対して傾斜する角度αは、0°以上60°以下で設定することができ、好ましくは、40°以上50°以下の範囲で設定することができる。本実施形態においては、45°で形成される。 The engaging portion inclined surface 32c and the engaged portion inclined surface 14b1 can be formed at any inclination angle, for example, at a right angle. Specifically, as shown in FIG. 5, the inclination angle α of the engaging portion inclined surface 32c and the engaged portion inclined surface 14b1 with respect to the horizontal line LV can be set to a value between 0° and 60°, and preferably between 40° and 50°. In this embodiment, it is formed at 45°.
