DOOR ROLLER REINFORCEMENT STRUCTURE, DOOR ROLLER REINFORCEMENT TOOL, AND DOOR ROLLER WITH REINFORCEMENT TOOL
PROBLEM TO BE SOLVED: To provide a door roller reinforcement structure, a reinforcement tool, and a door roller with the reinforcement tool that prevent damage caused by repeated fatigue while suppressing an increase in costs.SOLUTION: A door roller reinforcement structure includes: a door roller having a groove-form body part 2, an opening 2c for a wheel protrusion formed on a groove bottom of the groove-form body part 2, a pair of fixing plates 3 extending laterally from both side edge parts of the groove bottom of the groove-form body part 2 and having a first fixing screw hole 3a formed thereon, and a wheel 4 supported rotatably on the groove-form body part 2 and protruding partially from the opening 2c for a wheel protrusion; and a reinforcement tool 5 with a pair of collar pieces 5b respectively having a second fixing screw hole 5a that matches with the first fixing screw hole 3a, and a connection part 5c connecting the pair of collar pieces 5b and crossing over the wheel 4 while the pair of collar pieces is connected to the fixing plate 3 of the door roller. A fixing screw is inserted continuously into the first fixing screw hole 3a and the second fixing screw hole 5a, and the fixing screw is tightened on an object where the door roller is fixed. Thus, the collar piece 5b is connected with the fixing plate 3, and the reinforcement tool 5 is fixed on a door roller 1.SELECTED DRAWING: Figure 1
【課題】 コスト上昇を抑えつつ、繰返し疲労による破損を防止し得る、戸車補強構造、補強具及び補強具付き戸車を提供する。【解決手段】 溝形本体部2と、溝形本体部2の溝底に形成された車輪突出用開口部2cと、溝形本体部2の溝底両側端部から側方に延びるとともに第1固定螺子用孔3aが形成された一対の固定板3と、溝形本体部2に回転自在に支持されるとともに車輪突出用開口部2cから一部を突出させた車輪4と、を備える戸車と、第1固定螺子用孔3aに合致する第2固定螺子用孔5aを其々が備える一対の鍔片5bと、一対の鍔片5bを連結するとともに一対の鍔片を戸車の固定板3に接合させた状態で車輪4を跨ぐように形成された連結部5cと、を備える補強具5と、を備え、第1固定螺子用孔3a及び第2固定螺子用孔5aに固定螺子を連通し、該固定螺子を戸車取付対象に螺締することにより、固定板3に鍔片5bを接合させて戸車1に補強具5を固定する。【選択図】 図1
