<p>A safety device for a nailer (2) of the type provided with actuating means for the expulsion of a nail, staple or the like in a shooting direction and comprising a movable element (4) movable between a locking condition (B) wherein the nailer is inhibited from operation and a release condition (S) wherein the movable element (4) does not block the nailer and wherein it is possible the firing of the nail by actuating a trigger (6) of said nailer (2). The device (1) comprises at least one locking means (3) having a stopping end (5) movable between a stop condition (R) in which interferes with an abutment means (7) fixed to or carried out onto the movable element (4) stopping it in said locking condition (B) and an armed condition (A) wherein the stopping end (5) allows the translation of said abutment means (7) allowing the latter (7) to reach the release condition (S). Said locking means (3) being also provided of elastic means (9) acting in the direction of the stopping condition (R) and arming means (11) to act in contrast to the elastic means (9) and to shift the locking means (3) and the respective stopping end (5) in the armed condition (A). The operator, to put the nailer in the armed and release conditions, must act on arming means (11) freeing the abutment means (7) from the stopping end (5) and he must place the movable element (4) in the release condition (S) wherein the device can shoot the nail by acting on the trigger (6).</p> |
