【発明の属する技術分野】
この発明は、照明器具等の梱包用エンドパッドに関するものである。
【０００２】
【従来の技術】
器具の軽量化、省材料化を図る中で器具強度が若干弱くなる場合があり、そのため従来の梱包では器具が耐えきれず、器具の変形をきたす場合があった。そこで、段ボール強度を高くすると、段ボール積段強度（垂直荷重）は強くなるが、端面および側面からの梱包落下衝撃により段ボールの強さが災いして器具が変形してしまう。また、逆に段ボール強度を弱くすると積段強度（垂直荷重）が弱くなり、段ボールの座屈が発生してしまう。
【０００３】
そのため落下等による衝撃から守るため、箱型の段ボールの四隅に緩衝パッドを入れていたが、緩衝パッド点数が多いためコスト高となる。また、緩衝パッドを作る作業および入れ込む作業に手間がかかる。また、箱型の段ボールは金属製のステッチャにより止められているので、梱包廃却時においても材料の分離が煩わしく手間がかかっていた。また、器具の強度的に強い部分であるコーナ部四隅のみに緩衝パッドを当てていたため、トラック輸送上での振動等により、器具コーナ部と段ボールの擦れにより器具の塗装が剥がれるという問題があった。
【０００４】
また、１枚の段ボール材からなる包装装置もあった（例えば、特許文献１）。この場合、底面壁の両端に立設されるつま面壁に、端部緩衝体およびその両側に一対の側部緩衝体がそれぞれ形成されている。これにより、緩衝パッドが不要となるため、上記の問題は解消される。

【０００６】
【発明が解決しようとする課題】
しかしながら、特許文献１においては、底面壁とその両側の一対の側面壁およびフラップ壁からなる器具の包装部分と、端部緩衝体および側部緩衝体とが一体に形成されているため、構造が複雑になるとともに、包装する器具の数や長さ寸法に対応できない等の問題がある。
【０００７】
したがって、この発明の目的は、落下等による衝撃に耐え得ることができ、組立て作業が容易で、振動により被梱包体の塗装が剥がれることがなく、被梱包体の数や寸法形状を変更しても梱包できる梱包用エンドパッドを提供することである。
【０００８】
【課題を解決するための手段】
上記課題を解決するためにこの発明の請求項１記載の梱包用エンドパッドは、１枚の段ボールからなり、被梱包体の端部に配置される梱包用エンドパッドであって、前記段ボールの一端側に形成され前記被梱包体の端部の下面を載せる載置部と、この載置部の両側を含む前記段ボールの両縁部を折曲することで前記載置部の両側に形成され前記被梱包体の端部の両側面を被覆する一対の側片部と、前記段ボールの両縁部のうち前記一対の側片部に各々隣接する部分を重ね合わせるように折曲して前記被梱包体の端面を被覆する一対の端片部と、前記段ボールの他端側を折曲して前記端片部を被覆するとともに前記被梱包体の端部の上面を被覆する被覆片部とを備えた。
【０００９】
このように、段ボールの一端側に形成され被梱包体の端部の下面を載せる載置部と、この載置部の両側を含む段ボールの両縁部を折曲することで載置部の両側に形成され被梱包体の端部の両側面を被覆する一対の側片部と、段ボールの両縁部のうち一対の側片部に各々隣接する部分を重ね合わせるように折曲して被梱包体の端面を被覆する一対の端片部と、段ボールの他端側を折曲して端片部を被覆するとともに被梱包体の端部の上面を被覆する被覆片部とを備えたので、被梱包体の端部が載置部、側片部、端片部および被覆片部で覆われ、積段強度を向上させるために段ボール強度を高くした場合でも、落下等による衝撃に耐え得ることができる。このため、被梱包体である器具の端面および側面の強度が低い場合でも、器具変形、打痕等を発生させることがない。また、従来に比較して部品点数が削減され、段ボール使用量も削減できる。これに伴い梱包および解体作業が容易に行える。また、器具の端部のみに配置されるため、器具の数や寸法形状を変更しても対応できる。また、器具が梱包内で動かないようになり、トラック輸送上で振動等でも段ボールと器具コーナ部が擦れることがないので、塗装は剥がれない。
【００１０】
請求項２記載の梱包用エンドパッドは、請求項１記載の梱包用エンドパッドにおいて、内側の端片部とこれに隣接する側片部との間、および内側の端片部の端部に内緩衝部を設けた。このように、内側の端片部とこれに隣接する側片部との間、および内側の端片部の端部に内緩衝部を設けたので、被梱包体側からの衝撃を緩和することができる。
【００１１】
請求項３記載の梱包用エンドパッドは、請求項１または２記載の梱包用エンドパッドにおいて、外側の端片部とこれに隣接する側片部との間、および外側の端片部の端部に外緩衝部を設けた。このように、外側の端片部とこれに隣接する側片部との間、および外側の端片部の端部に外緩衝部を設けたので、外部からの衝撃を緩和することができる。
【００１２】
請求項４記載の梱包用エンドパッドは、請求項１，２または３記載の梱包用エンドパッドにおいて、一対の端片部は、平行かつ一定の間隔をあけて配置される。このように、一対の端片部は、平行かつ一定の間隔をあけて配置されるので、トラック輸送による振動、および作業者が誤って梱包を落下させた場合でも被梱包体を変形させない。
【００１３】
請求項５記載の梱包用エンドパッドは、請求項２記載の梱包用エンドパッドにおいて、内緩衝部は、内側の端片部とこれに隣接する側片部との間を複数回折込みしてなる。このように、内緩衝部は、内側の端片部とこれに隣接する側片部との間を複数回折込みしてなるので、器具コーナ部をこれに対応した折込みに当接させることで、被梱包体が梱包内で動かないようになる。
【００１４】
請求項６記載の梱包用エンドパッドは、請求項５記載の梱包用エンドパッドにおいて、内緩衝部の折曲線に被梱包体が当接する。このように、内緩衝部の折曲線に被梱包体が当接するので、請求項５の作用効果に加えてさらに被梱包体の位置ずれを防止することができる。
【００１５】
請求項７記載の梱包用エンドパッドは、請求項１，２，３，４，５または６記載の梱包用エンドパッドにおいて、一対の端片部が対向する位置で、外側の端片部に爪部を設け、この爪部に係止する穴部を内側の端片部に設けた。このように、一対の端片部が対向する位置で、外側の端片部に爪部を設け、この爪部に係止する穴部を内側の端片部に設けたので、一対の端片部が一体となり、被梱包体の端部に内側の端片部を挟持させることができる。
【００１６】
請求項８記載の梱包用エンドパッドは、請求項１，２，３，４，５，６または７記載の梱包用エンドパッドにおいて、載置部の一対の端片部が配置される部分に位置決め穴を設け、この位置決め穴に嵌合する位置決め爪を前記端片部に設けた。このように、載置部の一対の端片部が配置される部分に位置決め穴を設け、この位置決め穴に嵌合する位置決め爪を端片部に設けたので、一対の端片部を載置部に対して位置決めすることができる。
【００１７】
請求項９記載の梱包用エンドパッドは、請求項１，２，３，４，５，６，７または８記載の梱包用エンドパッドにおいて、被梱包体の内寸幅と略同寸法を有し、前記被梱包体の内部に沿うように折り込む仮固定爪部を被覆片部に設けた。このように、被梱包体の内寸幅と略同寸法を有し、前記被梱包体の内部に沿うように折り込む仮固定爪部を被覆片部に設けたので、エンドパッドの仮保持ができ、梱包組立て作業者がスムーズに組立てることができる。
【００１８】
請求項１０記載の梱包用エンドパッドは、請求項８記載の梱包用エンドパッドにおいて、被覆片部に切り込みを入れ折り曲げることにより、外側の端片部の端部に当接させて、外緩衝部近傍の位置決め爪のはずれを防止する外緩衝部外れ防止爪を設けた。このように、被覆片部に切り込みを入れ折り曲げることにより、外側の端片部の端部に当接させて、外緩衝部近傍の位置決め爪のはずれを防止する外緩衝部外れ防止爪を設けたので、エンドパッドを装着した状態で外装をラップする際に、位置決め爪と位置決め穴の係止が確実となり、外緩衝部が飛び出すことがない。
【００１９】
請求項１１記載の梱包用エンドパッドは、請求項１，２，３，４，５，６，７，８，９または１０記載の梱包用エンドパッドにおいて、外側の端片部に、内側の端片部に向けて折曲可能な位置ずれ防止爪を設けた。このように、外側の端片部に、内側の端片部に向けて折曲可能な位置ずれ防止爪を設けたので、特に内側の端片部の端部は被梱包体の長手方向の力に対して弱く、トラック輸送の振動等による器具のずれが大きいが、それに耐えうるように位置ずれ防止爪により内緩衝部のずれを防ぐことができる。
【００２０】
請求項１２記載の梱包用エンドパッドは、請求項１１記載の梱包用エンドパッドにおいて、位置ずれ防止爪は、被梱包体の強度が高い箇所に配置されている。このように、位置ずれ防止爪は、被梱包体の強度が高い箇所に配置されているので、位置ずれ防止爪を設けることで内緩衝部が緩衝材としての働きが低減する可能性があるが、位置ずれ防止爪を被梱包体の相対的に強い部分に当てることで被梱包体の変形を防止する。
【００２１】
請求項１３記載の梱包用エンドパッドは、請求項５または６記載の梱包用エンドパッドにおいて、内緩衝部付近に切り込みを入れて弾性を持たせた。このように、内緩衝部付近に切り込みを入れて弾性を持たせたので、段ボールの反発を抑え仮固定しやすくなる。
【００２２】
請求項１４記載の梱包用エンドパッドは、請求項６記載の梱包用エンドパッドにおいて、被梱包体が当接する内緩衝部付近に複数の穴をあけて弾性を持たせた。このように、被梱包体が当接する内緩衝部付近に複数の穴をあけて弾性を持たせたので、段ボールの反発を抑え仮固定しやすくなる。
【００２３】
請求項１５記載の梱包用エンドパッドは、請求項１，２，３，４，５，６，７，８，９，１０，１１，１２，１３または１４記載の梱包用エンドパッドにおいて、被覆片部の端片部に対向する部分を外装エンド部とし、この外装エンド部が載置部と垂直に折り曲げられるように、前記被覆片部と側片部に垂直位置合わせ部を設けた。このように、被覆片部の端片部に対向する部分を外装エンド部とし、この外装エンド部が載置部と垂直に折り曲げられるように、被覆片部と側片部に垂直位置合わせ部を設けたので、外装エンド部が斜めになることにより梱包積圧強度が低下することを防止できる。
【００２４】
請求項１６記載の梱包用エンドパッドは、請求項１，２，３，４，５，６，７，８，９，１０，１１，１２，１３，１４または１５記載の梱包用エンドパッドにおいて、被梱包体の接触面を段ボール表面にした。このように、被梱包体の接触面を段ボール表面にしたので、被梱包体である器具の塗装の擦れを抑えることができる。
【００２５】
【発明の実施の形態】
この発明の実施の形態を図１ないし図８に基づいて説明する。図１はこの発明の実施の形態の梱包用エンドパッドの組立て説明図、図２はこの発明の実施の形態の梱包用エンドパッドの展開図、図３はこの発明の実施の形態の梱包用エンドパッドの一部組立てた状態の平面図である。
【００２６】
図１に示すように、この梱包用エンドパッドは、１枚の段ボールからなり、被梱包体である器具の端部に配置されるもので、段ボールの一端側に形成され器具の端部の下面を載せる載置部１と、この載置部１の両側を含む段ボールの両縁部を折曲することで載置部１の両側に形成され器具の端部の両側面を被覆する一対の側片部２，３と、段ボールの両縁部のうち一対の側片部２，３に各々隣接する部分を重ね合わせるように折曲して器具の端面を被覆する一対の端片部４，５と、段ボールの他端側を折曲して端片部４，５を被覆するとともに器具の端部の上面を被覆する被覆片部６とを備えている。被覆片部６の端片部５に対向する部分を外装エンド部７とする。
【００２７】
また、内側の端片部４とこれに隣接する側片部２との間、および内側の端片部４の端部に内緩衝部８を設け、外側の端片部５とこれに隣接する側片部３との間、および外側の端片部５の端部に外緩衝部９を設けている。内緩衝部８は、内側の端片部４とこれに隣接する側片部２との間を複数回折込みしてなる。内緩衝部８の折曲線に器具が当接する（面当たりではなく線当たりとなる）。
【００２８】
この場合、載置部１の両側を含む段ボールの両縁部が、一対の側片部２，３を残して被覆片部６および外装エンド部７と分離されている。この部分を載置部１側へ折曲することで一対の端片部４，５となる。この際、内側の端片部４に上記のように内緩衝部８を形成しながら先端を折り曲げて外側の側片部３の内側に配置する。また、同様に外側の端片部５に上記のように外緩衝部９を形成しながら先端を折り曲げて内側の側片部２の外側に配置する。また、エンドパッドのそれぞれの折り部１８は、罫線のみならずミシン目を入れて折り易くしている。さらに仮固定し易いように反発の大きい端片部４、緩衝部８には大きくスリットを入れている（図２）。梱包完成状態で外から見える端片部５、緩衝部９にはミシン目のみ入れている。
【００２９】
また、図２および図３に示すように、一対の端片部４，５は、平行かつ一定の間隔をあけて配置される。一対の端片部４，５が対向する位置で、外側の端片部４，５に爪部１０を設け、この爪部１０に係止する穴部１１を内側の端片部４に設けている。また、載置部１の一対の端片部４，５が配置される部分に位置決め穴１２を設け、この位置決め穴１２に嵌合する位置決め爪１３を端片部４，５に設けている。
【００３０】
さらに、器具の内寸幅と略同寸法を有し、器具の内部に沿うように折り込む仮固定爪部１４を被覆片部６に設けている。また、被覆片部６に切り込みを入れ折り曲げることにより、外側の端片部５の端部に当接させて、外緩衝部９近傍の位置決め爪１３のはずれを防止する外緩衝部外れ防止爪１５を設けている。また、外側の端片部５に、内側の端片部４に向けて折曲可能な位置ずれ防止爪１６を設けている。
【００３１】
この場合、穴部１１の幅寸法ａに対し爪部１０の根元側は略寸法ａとして切り起こし、その端部はａ＋αとする。これにより爪部１０が抜け難くなる。仮固定爪１４は上から抑え込んで器具２０の天井当たり部２０ａに引っ掛ける（図６参照）。天井当たり部２０ａの曲げ代は５ｍｍ程度しかないため、容易に外れないように外れ方向と垂直に罫線またはミシン目１４ａを入れている。また、内緩衝部８の先端側と外緩衝部９の先端側の位置が決まり難いために、それぞれ２箇所に位置決め穴１２を設けているが、そのうちの一つは内緩衝部８と外緩衝部９とで共用した穴になっている。
【００３２】
また、内緩衝部８付近に切り込み（半切り）を入れて塗装擦れ防止部１７を形成し弾性を持たせている。これにより梱包振動等による器具の塗装擦れを防いでいる。または、器具２０が当接する内緩衝部８付近に複数の穴をあけて弾性を持たせてもよい。また、エンドパッドの展開状態では略四角形となり、無駄の少ない形状としている。また、器具２０と接触面を段ボール表面（凹凸の少ない面）とし、器具塗装の擦れを抑えている。
【００３３】
次に上記梱包用エンドパッドを用いて器具を梱包した状態について説明する。図５に示すように、梱包する器具２０は、ランプが装着される器具本体２１および反射板２２（（ｂ），（ｃ）において反射板は図示せず）を備えた照明器具である。器具本体２１は、図６に示すように、天井当たり部２０ａを有する。梱包時には、図７（ａ）に示すように器具２０を１台入れる場合、（ｂ）に示すように器具２０を２台入れる場合があり、２３が器具強度が高い部分、２４が器具強度が低い部分を示す。
【００３４】
図３に示すように、曲げ位置と器具コーナ部が合うように内緩衝部８を折り曲げ、器具２０がずれないようにしている。器具端面と内側の端片部４との間に空間ｃを設けている。この空間ｃはトラック輸送による振動、および作業者が誤って梱包を端面側から落下させた場合でも器具２０の変形をさせないため５〜１５ｍｍ程度あけている（器具質量により異なる）。また、同様の理由により内側の端片部４と外側の端片部５との間に２〜５ｍｍ程度の空間ｄを設けるとともに、内緩衝部８と外緩衝部９との間に２〜１０ｍｍ程度の空間を設けている。
【００３５】
また、先端側の内緩衝部８は位置決め爪１３と位置決め穴１２があるものの、基端側の内緩衝部８に比べて器具長手方向の力に対して弱く、トラック輸送の振動等による器具ずれが大きいが、位置ずれ防止爪１６を折り返すことにより先端側の内緩衝部８のずれを防いでいる。この位置ずれ防止爪１６を設けることで、ずれ防止の役割は果たすものの、逆に緩衝材としての働きが低減し、梱包落下等により器具２０のこの部分が変形する可能性がある。そこで、この位置ずれ防止爪１６の位置を器具２０の相対的に強い部分に当てることで器具変形を防止している。具体的には、図７に示したように器具強度が高い部分２３に位置ずれ防止爪１６を当てればよい。そのため、図７（ａ）の場合は、図４（ａ）に示すように、位置ずれ防止爪１６を下部に形成し、図７（ｂ）の場合は、図４（ｂ）に示すように、位置ずれ防止爪１６を中央に形成する。
【００３６】
また、外緩衝部９は位置決め爪１３と位置決め穴１２があるものの、万一外れた場合、エンドパッドに外装をラップする際に外緩衝部９が飛び出すことがあるが、外緩衝部外れ防止爪１５を折り込むことで外れを防止している。また、外装エンド部７が載置部１と垂直に折り曲げられるように、被覆片部６と側片部２，３に垂直位置合わせ部１９を設けている。
【００３７】
次に梱包手順について説明する。図８はこの発明の実施の形態の梱包用エンドパッドを用いた梱包手順を示す説明図である。
【００３８】
自動梱包の場合、図８（ａ）に示すように、エンドパッドの載置部１上に器具２０を１台または複数台載せる（図面では２台）。複数台の場合は器具２０間に器具パッド２５を入れる。外装エンド部７および被覆片部６を折り込む（エンドパッドは人手にて折り込む）。このとき、梱包組立て作業者がスムーズに組立てできるように仮固定爪１４を上から抑えることでエンドパッドの仮保持がきる。次に図８（ｂ）に示すように、器具２０を載せたエンドパッドを機械でつかみ、外装２６の上に載せる（外装２６に接着剤２７を塗布しておく）。機械で外装２６を折り込み、テープ封緘する。
【００３９】
この場合、外装２６の折り込みやコンベア移動等の振動により先端側の外緩衝部９が外れないように外緩衝部はずれ防止爪１５が必要である。またさらに安全のために被覆片部６から側片部２，３にかけてテープ止めすることもあり得る。このとき、人手によるため外装エンド部７が垂直に折曲されないことがあり、斜めになることにより梱包積圧強度が低下してしまう。したがって、外装エンド部７が垂直になるように垂直位置合わせ部１９を目印にテープ止めを行う。
【００４０】
手梱包の場合、外装２６に接着剤２７を塗布し、エンドパッドを貼る。載置部上に器具２０を１台または複数台載せる。複数台の場合は、器具２０間に器具パッド２５を入れる。外装エンド部７および被覆片部６を折り込む。外装２６を折り込み、テープ封緘する。
【００４１】
以上のようにこの実施の形態によれば、器具２０の端部が載置部１、側片部２，３、端片部４，５、および被覆片部６で覆われ、積段強度を向上させるために段ボール強度を高くした場合でも、落下等による衝撃に耐え得ることができる。このため、器具２０の端面および側面の強度が低い場合でも、器具変形、打痕等を発生させることがない。また、従来に比較して部品点数が削減され、段ボール使用量も削減できる。これに伴い梱包および解体作業が容易に行える。
【００４２】
また、器具２０の端部のみに配置されるため、器具２０の数や寸法形状を変更しても対応できる。また、器具２０が梱包内で動かないようになり、トラック輸送上で振動等でも段ボールと器具コーナ部が擦れることがないので、塗装は剥がれない。
【００４３】
【発明の効果】

TECHNICAL FIELD OF THE INVENTION
The present invention relates to an end pad for packing a lighting fixture or the like.
[0002]
[Prior art]
In order to reduce the weight and material of the equipment, the strength of the equipment may be slightly weakened, so that the conventional packaging may not be able to withstand the equipment, resulting in deformation of the equipment. Therefore, when the cardboard strength is increased, the cardboard stacking strength (vertical load) is increased, but the strength of the cardboard is impaired by the impact of packing falling from the end face and the side face, and the appliance is deformed. Conversely, if the cardboard strength is weakened, the stacking strength (vertical load) is weakened, and buckling of the cardboard occurs.
[0003]
For this reason, buffer pads are provided at the four corners of the box-shaped cardboard in order to protect from impacts caused by dropping or the like, but the number of buffer pads increases the cost. In addition, it takes time to make and insert the buffer pad. Further, since the box-shaped cardboard is stopped by a metal stitcher, separation of materials is troublesome and time-consuming even at the time of packing and disposal. Further, since buffer pads are applied only to the four corners of the corner portion, which is a strong part of the appliance, there is a problem that the painting of the appliance is peeled off due to friction between the appliance corner portion and the corrugated cardboard due to vibrations during truck transportation and the like. .
[0004]
There is also a packaging device made of one corrugated cardboard material (for example, Patent Document 1). In this case, an end cushion and a pair of side cushions are formed on both sides of the end cushion on the toe wall formed on both ends of the bottom wall. This eliminates the need for a buffer pad, thus solving the above problem.
[0005]
[Patent Document 1]
JP-A-2000-128151 (paragraphs 0025 to 0027, FIGS. 1 to 3)
[0006]
[Problems to be solved by the invention]
However, in Patent Literature 1, since the packaging portion of the appliance including the bottom wall, the pair of side walls and the flap wall on both sides thereof, and the end cushioning member and the side cushioning member are integrally formed, the structure is reduced. There is a problem that it becomes complicated, and it is not possible to cope with the number and length of the instruments to be packed.
[0007]
Therefore, an object of the present invention is to be able to withstand the impact due to dropping, etc., to facilitate the assembling work, to prevent the coating of the packaged object from being peeled off by vibration, and to change the number and size and shape of the packaged object. Is to provide a packing end pad that can also be packed.

BEST MODE FOR CARRYING OUT THE INVENTION
An embodiment of the present invention will be described with reference to FIGS. FIG. 1 is an explanatory view for assembling a packing end pad according to an embodiment of the present invention, FIG. 2 is an exploded view of the packing end pad according to the embodiment of the present invention, and FIG. 3 is a packing end according to the embodiment of the present invention. FIG. 3 is a plan view showing a partially assembled pad.
[0026]
As shown in FIG. 1, this packing end pad is made of one piece of cardboard and is arranged at the end of the device to be packed, and is formed at one end of the cardboard and the lower surface of the end of the device. And a pair of sides formed on both sides of the mounting portion 1 to cover both side surfaces of the end portion of the instrument by bending both edges of the cardboard including both sides of the mounting portion 1 A pair of end pieces 4, 5 for covering the end face of the appliance by bending the pieces 2, 3 and the portions adjacent to the pair of side pieces 2, 3 of both edges of the cardboard so as to overlap each other. And a cover piece 6 for bending the other end of the cardboard to cover the end pieces 4 and 5 and to cover the upper surface of the end of the instrument. A part of the covering piece part 6 facing the end piece part 5 is referred to as an exterior end part 7.
[0027]
In addition, an inner buffer 8 is provided between the inner end piece 4 and the side piece 2 adjacent thereto and at the end of the inner end piece 4, and the outer end piece 5 is adjacent to this. An outer buffer 9 is provided between the side piece 3 and at an end of the outer end piece 5. The inner buffer portion 8 is formed by diffracting a plurality of times between the inner end piece 4 and the side piece 2 adjacent thereto. The tool abuts on the fold curve of the inner buffer portion 8 (it is not a surface but a line).
[0028]
In this case, both edges of the cardboard including both sides of the mounting portion 1 are separated from the covering piece portion 6 and the exterior end portion 7 except for a pair of side pieces 2 and 3. This portion is bent toward the mounting portion 1 to form a pair of end pieces 4 and 5. At this time, the tip is bent while forming the inner buffer portion 8 on the inner end piece 4 as described above, and is disposed inside the outer side piece 3. Similarly, while forming the outer buffer portion 9 on the outer end piece 5 as described above, the tip is bent and disposed outside the inner side piece 2. Also, each folded portion 18 of the end pad is not only ruled but also perforated to facilitate folding. Further, large slits are formed in the end piece portion 4 and the buffer portion 8 which have a large rebound so as to be easily temporarily fixed (FIG. 2). Only the perforations are provided in the end piece 5 and the buffer 9 that are visible from the outside in the completed package state.
[0029]
Further, as shown in FIGS. 2 and 3, the pair of end pieces 4, 5 are arranged in parallel and at a constant interval. At the position where the pair of end pieces 4 and 5 are opposed to each other, a claw 10 is provided on the outer end pieces 4 and 5, and a hole 11 for engaging with the claw 10 is provided on the inner end piece 4. I have. A positioning hole 12 is provided in a portion of the mounting portion 1 where the pair of end pieces 4 and 5 are arranged, and a positioning claw 13 that fits into the positioning hole 12 is provided in the end pieces 4 and 5.
[0030]
Further, a temporary fixing claw portion 14 having substantially the same dimension as the inner width of the device and being folded along the inside of the device is provided on the covering piece portion 6. Also, by making a cut in the covering piece 6 and bending it, it comes into contact with the end of the outer end piece 5 to prevent the positioning claw 13 near the outer buffer 9 from coming off. Is provided. Further, the outer end piece 5 is provided with a position shift preventing claw 16 that can be bent toward the inner end piece 4.
[0031]
In this case, the root side of the claw portion 10 is cut and raised with a substantially dimension a with respect to the width dimension a of the hole portion 11, and its end is a + α. This makes it difficult for the claw portion 10 to come off. The temporary fixing claw 14 is held down from above and hooked on the ceiling contact portion 20a of the device 20 (see FIG. 6). Since the margin of bending of the ceiling contact portion 20a is only about 5 mm, ruled lines or perforations 14a are provided perpendicularly to the disengagement direction so as not to be easily dislodged. In addition, since it is difficult to determine the positions of the distal end side of the inner buffer 8 and the distal end of the outer buffer 9, two positioning holes 12 are provided, one of which is the inner buffer 8 and the outer buffer 9. The hole is shared with the part 9.
[0032]
In addition, a cut (half cut) is made in the vicinity of the inner buffer portion 8 to form the coating abrasion preventing portion 17 to provide elasticity. This prevents paint rubbing of the appliance due to packing vibration and the like. Alternatively, a plurality of holes may be formed in the vicinity of the inner buffer portion 8 with which the device 20 comes into contact, so as to have elasticity. Further, when the end pad is in a deployed state, the end pad has a substantially square shape, and has a shape with little waste. In addition, the contact surface with the device 20 is a corrugated cardboard surface (a surface with little unevenness) to suppress rubbing of the device coating.
[0033]
Next, a state in which the device is packed using the packing end pad will be described. As shown in FIG. 5, the device 20 to be packed is a lighting device including a device body 21 to which a lamp is mounted and a reflector 22 (reflectors are not shown in (b) and (c)). The apparatus main body 21 has a ceiling contact part 20a as shown in FIG. At the time of packing, when one device 20 is inserted as shown in FIG. 7A, two devices 20 may be inserted as shown in FIG. 7B, 23 is a portion where the device strength is high, and 24 is a portion where the device strength is high. Shows the lower part.
[0034]
As shown in FIG. 3, the inner buffer portion 8 is bent so that the bending position and the corner portion of the device are aligned, so that the device 20 does not shift. A space c is provided between the end face of the instrument and the inner end piece 4. The space c is provided with a space of about 5 to 15 mm (depending on the mass of the equipment) so that the equipment 20 is not deformed even if the package is accidentally dropped from the end face side due to the vibration caused by truck transportation and the worker accidentally drops the package from the end face side. For the same reason, a space d of about 2 to 5 mm is provided between the inner end piece 4 and the outer end piece 5, and 2 to 10 mm is provided between the inner buffer 8 and the outer buffer 9. About space is provided.
[0035]
In addition, although the inner buffer 8 on the distal side has the positioning claw 13 and the positioning hole 12, it is weaker than the inner buffer 8 on the proximal end against the force in the longitudinal direction of the equipment, and the equipment shifts due to the vibration of truck transportation and the like. However, the displacement of the displacement prevention claws 16 prevents the displacement of the inner buffer 8 on the distal end side. By providing the position shift preventing claws 16, although the role of preventing the shift is fulfilled, the function as a cushioning material is reduced, and there is a possibility that this part of the device 20 is deformed due to a dropping of the packing. Therefore, the position of the displacement prevention claw 16 is applied to a relatively strong portion of the device 20 to prevent the device from being deformed. Specifically, as shown in FIG. 7, the position shift preventing claw 16 may be applied to the portion 23 where the instrument strength is high. For this reason, in the case of FIG. 7A, the position shift preventing claw 16 is formed at the lower part as shown in FIG. 4A, and in the case of FIG. 7B, as shown in FIG. Then, the displacement preventing claw 16 is formed at the center.
[0036]
Although the outer buffer 9 has the positioning claw 13 and the positioning hole 12, if it comes off, the outer buffer 9 may pop out when wrapping the exterior on the end pad. 15 is prevented from coming off by folding. In addition, a vertical alignment portion 19 is provided on the covering piece 6 and the side pieces 2 and 3 so that the exterior end 7 is bent perpendicularly to the mounting section 1.
[0037]
Next, the packing procedure will be described. FIG. 8 is an explanatory view showing a packing procedure using the packing end pad according to the embodiment of the present invention.
[0038]
In the case of automatic packing, as shown in FIG. 8A, one or a plurality of instruments 20 are placed on the placing portion 1 of the end pad (two in the drawing). In the case of a plurality, the device pad 25 is inserted between the devices 20. The exterior end portion 7 and the covering piece portion 6 are folded (the end pad is folded manually). At this time, the temporary fixing claws 14 are held down from above so that the package assembling worker can assemble smoothly, so that the end pads can be temporarily held. Next, as shown in FIG. 8B, the end pad on which the device 20 is placed is grasped by a machine and placed on the exterior 26 (adhesive 27 is applied to the exterior 26). The outer casing 26 is folded by a machine and sealed with a tape.
[0039]
In this case, the outer buffer 9 must be provided with the stopper 15 so that the outer buffer 9 on the distal end side does not come off due to vibration such as folding of the exterior 26 or movement of the conveyor. Further, for safety, the tape may be applied from the covering piece 6 to the side pieces 2 and 3. At this time, the exterior end portion 7 may not be bent vertically due to manual operation, and the packing endurance strength may decrease due to the inclination. Therefore, tape fixing is performed using the vertical alignment portion 19 as a mark so that the exterior end portion 7 is vertical.
[0040]
In the case of manual packing, an adhesive 27 is applied to the exterior 26 and an end pad is attached. One or more instruments 20 are placed on the placement part. In the case of a plurality, the device pad 25 is inserted between the devices 20. The exterior end part 7 and the covering piece part 6 are folded. The exterior 26 is folded in and sealed with a tape.
[0041]
As described above, according to this embodiment, the end of the device 20 is covered with the mounting portion 1, the side pieces 2, 3, the end pieces 4, 5, and the coating piece 6, and the stacking strength is reduced. Even if the strength of the cardboard is increased to improve it, it can withstand the impact due to dropping or the like. For this reason, even if the strength of the end face and the side face of the tool 20 is low, the tool does not deform or dent. Further, the number of components is reduced as compared with the related art, and the amount of corrugated cardboard can be reduced. Accordingly, packing and dismantling operations can be easily performed.
[0042]
In addition, since it is arranged only at the end portion of the device 20, it is possible to cope with the case where the number, size and shape of the device 20 are changed. In addition, since the appliance 20 does not move in the package and the corrugated cardboard and the corner of the appliance do not rub even by vibration during truck transportation, the paint is not peeled off.
