DOOR CLOSER COVER AND DOOR CLOSER
To achieve both fire resistance and aesthetics.SOLUTION: A cover 12 covering a driving device of a door closer includes: a fall part, at least partly made of resin, including an underside, falling from the driving device in the event of a fire; and a metal residual part left on the driving device in the event of a fire. The residual part occupies at least the majority of a door surface side of an upper surface part. The fall part is made entirely of resin and further includes a front part and left and right side parts. The fall part has a screw boss projecting toward the residual part side, and the fall part is screwed to the residual part by screwing a screw 17 into the screw boss.SELECTED DRAWING: Figure 7
【課題】防火性と美観の両立を図る。【解決手段】ドアクローザの駆動装置を覆うカバー１２であって、下面部を含み、少なくとも一部が樹脂製であって、火災時に駆動装置から落ちる落下部と、火災時に駆動装置に残る金属製の残留部と、を有し、残留部は、上面部のうち少なくとも扉面側の大部分を占めており、落下部は、全体が樹脂製であって、正面部及び左右の側面部を更に含み、落下部は、残留部側に向けて突出するネジボスを有し、ネジボスにネジ１７が螺入されることにより残留部に落下部がネジ止めされている。【選択図】図７
