  • Patent number: 4927194
    Abstract: An interlock mechanism is provided for a latch assembly which releasably secures upper and lower cowl sections of an outboard motor. The interlock mechanism is movable between a locking position and a release position, and is normally disposed in its locking position, such as by a coil spring. The interlock mechanism is mounted to the latch handle, which is pivotably mounted to one of the cowl sections. A hook is interconnected with the latch handle, and is engageable with a catch assembly provided on the other of the cowl sections. The interlock assembly normally engages a stationary engagement pin provided on one of the cowl sections, which prevents accidental pivoting movement of the latch handle. The interlock mechanism is manually movable to its release position, so that the latch handle can be pivoted so as to disengage the hook from the catch mechanism.

  • Patent number: 4893850
    Abstract: An opening/closing device for detachably coupling a closure member to the open edge portion of a body includes a locking shaft provided upon the side of the body, a bracket secured to the closure member and having a notch defined therein, an operating lever having an end portion provided with a pawl portion for engaging the locking shaft within the open end region of the notch, and spring means provided upon the operating lever for biasing the pawl portion in the direction of engagement with the locking shaft. When the closure member is set upon the body, the notch is engaged with the locking shaft. The closure member is closed relative to the body by the engagement of the notch and pawl portion with the locking shaft. When the closure member is opened in a cantilevered state, this device serves as a hinge. By operating the operating lever against the biasing force of the spring means so as to disengage the pawl portion from the locking shaft, the closure member is separated from the body.

  • Patent number: 4458929
    Abstract: The subject of the invention is an automatic locking mechanism for a revolving shutter to protect the latter against unauthorized pulling up from the outside, using a locking device which is moved into the locking position after the revolving-shutter casing has been lowered. The device has a lateral axle bearing, with a round bearing element (11) for a belt pulley (2) and a fixed square bearing pin (8) connected thereto and the end of which is designed as a round cylinder. The belt pulley (2) has an annular web (2a) and the roller insertion cap (1) has an annular web (1a), the side webs (1a/2a) having different diameters and interlocking coaxially. A pivotable locking lever (6) engages positively through coinciding gaps. In the lowered state of the revolving-shutter casing, the lever (6) engages with the fixed bearing pin (8) and clamps belt pulley and roller insertion cap against unauthorized turning, so that the revolving-shutter roller connected to the roller insertion cap is also locked.

  • Patent number: 4424993
    Abstract: A latch mechanism for use in a street and roadway lighting luminaire. The latch mechanism operates generally in the same fashion as prior latch mechanisms to release the engagement between the upper and lower housings responsive to manual actuation of a pawl of the latch mechanism against the bias of a torsion spring. The present mechanism may be readily detached and replaced without the need for elaborate spring depressors. Two torsion springs are employed, one fitted to each side of the latch pawl to hold and bias the pawl. The springs can be released individually to enable removal of the pawl. On replacement, the pawl is slipped into the cast-in nesting arrangement with the two springs loosely fitted on the pawl. The springs are then depressed to their pawl-biasing condition to mount and affix the pawl to the lower housing.
