  • Patent number: 9150338
    Abstract: A locking system for an enclosure (10) wherein the enclosure (10) includes a base (12) and a moveable cover (14). The cover (14) is moveable only when a key operated slide (70) is moved by a key (26) inserted into a key slot (24). Once the cover (14) is moved, the key (26) cannot be removed from the key slot (24) until the cover (14) is returned to the closed positioned. A moveable latch (50) holds the cover (14) to the base (12). The key operated slide (70) selectively connects and disconnects from the latch (50) to allow the cover (14) to be moved. The latch (50) cooperates with a clip (94) on the slide (70) which allows the slide (70) to return to the locked position to allow the key (26) to be removed from the key slot (24) only when the cover (14) and the latch (50) are closed. One or two latches can be provided with a corresponding number of key operated slides (70). The key (26) is rotatable to move the slide (70) from an extended and locked position to a retracted and unlocked position.

  • Patent number: 8220298
    Abstract: A locking system for securely closing the lid on an enclosure, such as a grade level box, includes an L-bolt connected to a spring-biased slide member positioned on the underside of the lid. The L-bolt rotates in a slotted housing that securely retains the L-bolt under the lid. The slide member engages an abutment on the inside of the enclosure, when the lid is forced down over an opening in the enclosure, e.g., by foot pressure. Downward force on the lid progressively causes the latch to retract against the spring-bias from contact with the abutment and then snaps the latch into a spring-biased locking position under the abutment. The L-bolt is accessed from outside the lid, rotated by a proprietary socket wrench or similar tool, to retract the latch from its locking position sufficiently for removing the lid from the enclosure.

  • Patent number: 6694783
    Abstract: A locking cover plate can be selectively locked in position on a stortz pipe end fitting or can be unlocked and removed for access to the open pipe end. The cover plate includes a sliding plate that is driven laterally outward into a deployed state by rotating a drive bolt. The drive bolt is coupled to the sliding plate through a torque limiting coupling that transfers the rotation of the drive bolt to translating movement of the latch bar with a cam plate. Movement of the sliding plate is indicated through a front of the cover plate such that the user can identify whether the cover plate is locked on a fitting or simply placed on the fitting without the lock engaged.

  • Patent number: 6688146
    Abstract: A rotary closure (1) having a carrying body (5) which carries a plug-in section (6) for plugging into a plug-in opening, in which the plug-in section (6) can be arrested by a retaining element (37) which can be rendered operational or non-operational by a rotary handgrip (4) being rotated, it being possible for the rotary handgrip (4) to be blocked by a combination lock having a plurality of number disks (10). For realizing a rotary closure which is of straightforward, compact construction and which can be used to close plug-in openings of objects of different configurations, there is provided a pull member (33) which can be displaced axially by the rotary handgrip (4) being rotated and is intended for actuating the retaining element (37).

    Abstract: The invention relates to a rotary closure (1) having a carrying body (5) which carries a plug-in section (6) for plugging into a plug-in opening, in which the plug-in section (6) can be arrested by means of a retaining element (37) which can be rendered operational or non-operational by virtue of a rotary handgrip (4) being rotated, it being possible for said rotary handgrip (4) to be blocked by means of a combination lock having a plurality of number disks (10). For the purpose of realizing a rotary closure which is of straightforward, compact construction and which can be used to close plug-in openings of objects of different configurations, the invention proposes a pull member (33) which can be displaced axially by virtue of the rotary handgrip (4) being rotated and is intended for actuating the retaining element (37).

  • Publication number: 20030033840
    Abstract: A locking cap is selectively locked into place within a tubular opening, such as the open end of a standpipe used to charge a building sprinkler system. The locking cap has an expandable sleeve and a spreader member. As a key is turned, the spreader member is drawn into the expandable sleeve which is urged outward. The outward movement of the expandable sleeve increases a frictional component such that the expandable sleeve becomes frictionally locked within the tubular opening. The key has an end design that is complemented by an end of an actuator shaft such that the likelihood of unauthorized removal of the locking cap is reduced.

  • Patent number: 6435763
    Abstract: The present invention is provided with a key hole insertion fitted to a manhole cover, a manhole cover locking apparatus equipped with the key hole insertion, a manhole cover locking system, a method for unlocking the manhole cover, and a control system for opening and a closing manhole cover, which is designed to prevent an external access to the key hole of the manhole cover, thus attaining a sound and severe locking management. The electrical locking assembly can be added to conventional manhole covers in a simple way. The structure of the invention is characterized in a key hole insertion A inserted in a key hole 3b of the inner manhole cover 3 or the key hole 5b of the manhole cover 5 enough to engage pins 11b with engaging openings 12b of the cap holding member 12 secured to the key hole 3b or the key hole 5b. This allows the key hole insertion A to be locked to the key hole 3b or the key hole 5b.

  • Patent number: 6220064
    Abstract: A fuel filler assembly, in particular for a motor vehicle, having a filler, and a cap for closing a mouth of the filler and provided internally with a cylinder rotated by means of an operating key is disclosed. A reversible locking arrangement is provided for reversibly locking relative rotation of the cylinder with respect to the cap to selectively assume, when the cap is fitted closing the filler, a first operating position permitting relative rotation of the cylinder with respect to the cap and, hence, withdrawal of the operating key, and, when the cap is detached from the filler, a second operating position preventing relative rotation of the cylinder with respect to the cap and, hence, withdrawal of the operating key from the cylinder.

  • Patent number: 6199414
    Abstract: A quick release lock for a cover is provided. The cover may be a manhole cover for closing onto a manhole ring having a radially extended flange. The quick release lock mainly includes several angularly equal-spaced cross-shaped slots provided on the cover to communicate with through holes below them, and catch elements, push elements, and cotters in the same number as that of the cross-shaped slots. The catch element each is pivotally connected to and between two fixing plates provided at two opposite sides of each through hole. The cotter each is positioned in one cross-shaped slot and extended down into she through hole. The push element each is screwed on a bar portion of the cotter below the cover. When the cotter is depressed, the push element radially pushes the catch element outward to engage with a lower edge of the flange on the ring member and thereby firmly locks the cover to the ring member.
