Abstract
An example door closer includes a casing and a pinion rotatably mounted to the casing. The pinion is operable to rotate through a plurality of movement zones, and the door closer is configured to exert forces on the pinion as the pinion moves through the plurality of movement zones. The door closer further includes a plurality of adjustment mechanisms, each operable to adjust the force exerted on the pinion as the pinion travels through a corresponding movement zone. The casing is provided with indicia that correlate each of the adjustment mechanisms to the corresponding movement zone.
Claims22
A door closer, comprising:
- a casing;
- a pinion rotatably mounted to the casing for rotation through a plurality of movement zones;
- a rotatable adjustment mechanism mounted to the casing, wherein the rotatable adjustment mechanism comprises a valve configured to adjust an operating characteristic of the door closer for a particular movement zone of the plurality of movement zones;
- and
- a movement zone key provided at the door closer, the movement zone key comprising:
- a representation of a door swing, including representations of the plurality of movement zones;
- and
- a plurality of valve function indicia positioned to relate each valve function indicium with a corresponding movement zone of the plurality of movement zones, the plurality of valve function indicia comprising a first instance of a first valve function indicium, wherein the first instance of the first valve function indicium is positioned to relate the first instance of the first valve function indicium with the particular movement zone;
- wherein the door closer further comprises:
- a second instance of the first valve function indicium indicating that the rotatable adjustment mechanism is operable to adjust the operating characteristic for the particular movement zone;
- and
- a second indicium relating a first rotational direction with a first adjustment effected by rotating the rotatable adjustment mechanism in the first direction.
A door closer, comprising:
- a casing;
- a pinion rotatably mounted to the casing;
- a valve movably mounted to the casing, wherein movement of the valve adjusts a particular operating characteristic of the door closer within a particular movement zone of a plurality of movement zones;
- a movement zone key provided to the casing, the movement zone key comprising:
- a representation of a door swing, including representations of the plurality of movement zones;
- and
- a first instance of a valve function indicium positioned to indicate that the valve function indicium is associated with the particular movement zone;
- and
- a second instance of the valve function indicium provided to the casing, the second instance of the valve function indicium indicating that movement of the valve adjusts the particular operating characteristic of the door closer within the particular movement zone.
A door operator, comprising:
- a casing;
- a pinion rotatably mounted to the casing;
- an adjustment mechanism rotatably mounted to the casing, wherein the door operator is configured to perform a function in response to rotation of the adjustment mechanism, and wherein the function comprises adjusting an operating characteristic of the door operator within a particular movement zone;
- a movement zone key positioned on the casing, the movement zone key comprising:
- a representation of a door swing, including a representation of the particular movement zone;
- and
- a first instance of a functional indicium positioned to indicate that the functional indicium is associated with the particular movement zone;
- and
- a second instance of the functional indicium positioned on the casing to thereby identify the function of the adjustment mechanism.
