従来、この種の側溝蓋吊上具として、足車を備えた梃子本体に取手部を形成すると共に梃子本体の先端に開閉するアームを有する蓋掴み具を吊下してなる構造のものが知られている。
【０００５】
【発明が解決しようとする課題】
しかしながらこの従来構造の場合、側溝蓋の吊下専用構造となっており、他用途に使えずに汎用性に乏しく、それだけ、コスト低減を図ることが困難となっているという不都合を有している。
【０００６】
【課題を解決するための手段】
本発明はこのような不都合を解決することを目的とし、本発明のうちで、請求項１記載の発明は、車枠の後部に左右一対の把手体が突設され、該車枠の上部に荷台が設けられ、車枠の下部に一個の車輪及び接地脚が設けられた手押し車と、該手押し車に着脱自在及び位置調節自在に前方へ突設される支持杆体と、該支持杆体の前部に取り付けられ、該側溝蓋の両側面を掴持して吊上可能な掴持機構とからなり、上記掴持機構は、一対の作動リンクを支点軸によりＸ状に枢着し、該各作動リンクの下方端部に対向状にそれぞれ掴持部材を設け、該掴持部材の内面にゴムや合成樹脂等の弾性体を取付け、該各作動リンクの上方端部に一対の吊下リンクの外方端部をそれぞれ連結軸により枢着し、該一対の吊下リンクの内方端部を吊下軸により枢着連結し、該吊下軸に吊下部材を取付け、該吊下部材を支持杆体に一個の鎖体により一点支持状態に吊下連結してなり、かつ、上記支点軸と上記吊下軸との間に支点軸と吊下軸との離隔距離を規制して上記掴持部材の対向距離を規制するロック機構を設け、上記ロック機構は、上記支点軸にロック部材を回動自在に枢着し、該ロック部材に上記吊下軸に着脱自在に掛止可能な掛止溝部を設けてなることを特徴とする側溝蓋吊上具にある。
【０００７】
【発明の実施の形態】

【０００９】
３は掴持機構であって、上記支持杆体２の前部に取り付けられ、側溝Ｍ上の側溝蓋Ｗの両側面、この場合、側溝蓋Ｗの一方側面と側溝蓋Ｗの凹部Ｗ1の側面を掴持して吊上可能に設けられ、この場合、掴持機構３として、一対の作動リンク４・４を支点軸５によりＸ状に枢着し、各作動リンク４・４の下方端部に対向状にそれぞれ掴持部材６・６を設け、掴持部材６・６の内面にゴムや合成樹脂等の弾性体７・７を取付け、各作動リンク４・４の上方端部に一対の吊下リンク８・８の外方端部をそれぞれ連結軸９・９により枢着し、一対の吊下リンク８・８の内方端部を吊下軸１０により枢着連結し、吊下軸１０に二股状の吊下部材１１を取付け、吊下部材１１を支持杆体２に一個の鎖体１２により一点支持状態に吊下連結して構成している。
【００１０】
１３はロック機構であって、上記支点軸５と上記吊下軸１０との間に設けられ、この場合、上記支点軸５にロック部材１４を回動自在に枢着し、ロック部材１４に上記支点軸５に着脱自在に掛止可能なＵ溝状の掛止溝部１５を設け、ロック部材１４を回動して掛止溝部１５を吊下軸１０に掛止することにより支点軸５と吊下軸１０との離隔距離を規制して掴持部材６・６の対向距離を規制し、ロック部材１４を回動して掛止溝部１５を吊下軸１０から離反することにより支点軸５と吊下軸１０との離隔距離の規制を解放するように構成している。
【００１１】
この実施の形態例は上記構成であるから、車枠１ａの後部に左右一対の把手体１ｂ・１ｂが突設され、該車枠１ａの上部に荷台１ｃが設けられ、車枠１ａの下部に一個の車輪１ｄ及び接地脚１ｅが設けられた手押し車１に前方に着脱自在及び位置調節自在に突設して支持杆体２を取付け、各種の手押し車１の形態に対する支持杆体２の取付の融通性を確保し、この支持杆体２の前部に側溝蓋Ｗの両側面を掴持して吊上可能な掴持機構３が設けられているので、図５の如く、把手体１ｂ・１ｂを持ち上げて車輪１ｄを支点として掴持機構３を降下し、掴持機構３により側溝蓋Ｗの両側面を掴持し、掴持機構３により側溝蓋Ｗの両側面を掴持したのち、図１の如く、把手体１ｂ・１ｂを押下げることにより側溝蓋Ｗを上昇させて持ち上げ、そのまま側溝蓋Ｗを適宜位置に運搬することができ、手押し車１の一個の車輪１ｄを支点とする梃子作用により楽に側溝蓋Ｗを持ち上げたり、下げたりすることができ、このため、手押し車１の一個の車輪１ｄを支点とする梃子作用により楽に側溝蓋Ｗを持ち上げることができ、かつ、手押し車１から支持杆体２を取り外したり、又は、支持杆体２を取り付けたままで、各種の運搬作業を行うことができ、手押し車１のアタッチメントして使用することができ、汎用性を高めることができ、コスト低減を図ることができる。
【００１２】
又、この場合、上記掴持機構３として、一対の作動リンク４・４を支点軸５によりＸ状に枢着し、各作動リンク４・４の下方端部に対向状にそれぞれ掴持部材６・６を設け、掴持部材６・６の内面にゴムや合成樹脂等の弾性体７・７を取付け、各作動リンク４・４の上方端部に一対の吊下リンク８・８の外方端部をそれぞれ連結軸９・９により枢着し、一対の吊下リンク８・８の内方端部を吊下軸１０により枢着連結し、吊下軸１０に二股状の吊下部材１１を取付け、吊下部材１１を支持杆体２に一個の鎖体１２により一点支持状態で吊下連結して構成しているから、図６の如く、掴持部材６・６を側溝蓋Ｗ・Ｗ間に存在する凹部内に挿入配置して側溝蓋Ｗの一方側面と側溝蓋Ｗの凹部の側面に掴持部材６・６を対向位置し、図７の如く、ロック機構１３を解除して支持杆体２により吊下部材１１を上昇させると、吊下軸１０が上昇し、一対の吊下リンク８・８は吊下軸１０により開き動作すると共に作動リンク４・４は連結軸９・９を介して支点軸５を中心として開き動作し、このため、掴持部材６・６の対向距離は狭まって掴持部材６・６は側溝蓋Ｗの両側面を掴持することになり、掴持部材６・６により側溝蓋Ｗの両側面を確実に掴持することができ、又、吊下軸１０の降下により一対の吊下リンク８・８は吊下軸１０により閉じ動作すると共に作動リンク４・４は連結軸９・９を介して支点軸５を中心として閉じ動作し、このため、掴持部材６・６の対向距離は拡まって掴持部材６・６は側溝蓋Ｗの両側面を釈放することになり、又、この場合、上記支点軸５と上記吊下軸１０との間に支点軸５と吊下軸１０との離隔距離を規制して掴持部材６・６の対向距離を規制するロック機構１３を設けてなるから、掴持部材６・６の対向距離を規制することができ、隣り合う側溝蓋Ｗ・Ｗ間の隙間に容易に掴持部材６・６を挿入配置することができ、又、この場合、上記ロック機構１３として、上記支点軸５にロック部材１４を回動自在に枢着し、ロック部材１４に上記吊下軸１０に着脱自在に掛止可能な掛止溝部１５を設けてなるから、ロック部材１４の掛け外しにより掴持部材６・６の対向距離の規制を容易に行うことができると共に規制の解除を容易に行うことができ、作業性を向上することができる。
【００１３】
尚、本発明は上記実施の形態例に限らず、手押し車１、支持杆体２の形態及び掴持機構３、ロック機構１３の構造等は適宜変更して設計される。
【００１４】
【発明の効果】
本発明は上述の如く、請求項１記載の発明にあっては、車枠の後部に左右一対の把手体が突設され、該車枠の上部に荷台が設けられ、車枠の下部に一個の車輪及び接地脚が設けられた手押し車に前方に着脱自在及び位置調節自在に突設して支持杆体を取付け、各種の手押し車の形態に対する支持杆体の取付の融通性を確保し、この支持杆体の前部に側溝蓋の両側面を掴持して吊上可能な掴持機構が設けられているので、把手体を持ち上げて車輪を支点として掴持機構を降下し、掴持機構により側溝蓋の両側面を掴持し、掴持機構により側溝蓋の両側面を掴持したのち、把手体を押下げることにより側溝蓋を上昇させて持ち上げ、そのまま側溝蓋を適宜位置に運搬することができ、手押し車の一個の車輪を支点とする梃子作用により楽に側溝蓋を持ち上げたり、下げたりすることができ、このため、手押し車の一個の車輪を支点とする梃子作用により楽に側溝蓋を持ち上げることができ、かつ、手押し車から支持杆体を取り外したり、又は、支持杆体を取り付けたままで、各種の運搬作業を行うことができ、手押し車のアタッチメントして使用することができ、汎用性を高めることができ、コスト低減を図ることができ、かつ、上記掴持機構として、一対の作動リンクを支点軸によりＸ状に枢着し、各作動リンクの下方端部に対向状にそれぞれ掴持部材を設け、掴持部材の内面にゴムや合成樹脂等の弾性体を取付け、各作動リンクの上方端部に一対の吊下リンクの外方端部をそれぞれ連結軸により枢着し、一対の吊下リンクの内方端部を吊下軸により枢着連結し、吊下軸に吊下部材を取付け、吊下部材を支持杆体に一個の鎖体により一点支持状態で吊下連結して構成しているから、吊下部材の上昇により掴持部材の対向距離は狭まって掴持部材は側溝蓋の両側面を掴持することになり、掴持部材により側溝蓋Ｗの両側面を確実に掴持することができ、又、吊下部材の降下により掴持部材は側溝蓋Ｗを釈放することになり、更に、上記支点軸と上記吊下軸との間に支点軸と吊下軸との離隔距離を規制して掴持部材の対向距離を規制するロック機構を設けてなるから、掴持部材の対向距離を規制することができ、隣り合う側溝蓋間の隙間に容易に掴持部材を挿入配置することができ、又、更に、ロック機構として、上記支点軸にロック部材を回動自在に枢着し、ロック部材に上記吊下軸に着脱自在に掛止可能な掛止溝部を設けてなるから、ロック部材の掛け外しにより掴持部材の対向距離の規制を容易に行うことができると共に規制の解除を容易に行うことができ、作業性を向上することができる。
