  • Patent number: 7681421
    Abstract: An electrical panel lockout that locks the electrical panel door closed and prevents the panel cover from being removed. Two telescoping hollow tubes extend between two panel screws. Two slots in the ends of the hollow tubes slide under the screw heads of each of the loosened panel screws. The outer hollow tube and inner hollow tube extend across the panel door keeping it locked closed. The shackle of a padlock is inserted into one of the openings of the inner hollow tube to keep the device locked in the extended position onto the panel screws. The screw heads are encapsulated by the device rendering them inaccessible and preventing the electrical panel cover from being removed. Hollow tube extension fittings can be employed to increase the length of the device for use on electrical panels of larger widths. A guide screw attached to the inner hollow tube rides in a slot in the outer hollow tube to keep both tubes from separating.

    Abstract: A telescopic stay comprises a stay body including an inner arm and an outer arm into which the inner arm is slidably fitted. In order to lock the inner and outer arms in a pre-determined superposed position, a locking rod engages a locking hole in the inner arm by a locking spring disposed in a guide member attached onto the outer arm, but the guide member has a base portion passing through a flat board of the outer arm and a locking spring urges the guide member so that the base portion is forced against the inner face of the flat board portion. This requires no specific operation for securing the guide member and therefore the telescopic stay can be assembled with a reduced number of parts.

  • Patent number: 5927107
    Abstract: A locking device for protecting the contents of a container from theft includes an extension member having an adjustable length and a lock for inhibiting adjustment of the extension member's length when the lock is engaged. To secure the contents of a container from theft, the locking device is installed between two opposing surfaces, such as between two vertical wall surfaces, with the extension member extending across the container door with the door in its closed position. The locking device is installed by simply inserting each end of the extension member into suitable cavities formed in the opposing surfaces, or in brackets attached to the opposing surfaces, adjusting the length of the extension member as necessary. Thereafter, the lock can be engaged to prevent adjustment of the extension member's length, and thereby prevent removal of the ends of the extension member from the surface openings.

  • Patent number: 5799521
    Abstract: A security indicator has a two part telescopic locking bar attached to the handle of a door at one end and to the door or door jamb at the other end through an end piece. The device includes a cup or tube which encases the door handle, preventing use of the handle. The length of the bar is fixed by aligning apertures in each part of the telescopic locking bar to form a continuous aperture, inserting a frangible pin through the continuous aperture and locking the frangible pin in place with a padlock received by a hole in the frangible pin. The pin has a narrow portion which can be broken by relatively little human force. The device requires someone who does not have the key to the padlock on the frangible pin to break the frangible pin to enter a door fixed with the device. A broken pin alerts the occupant that an entry has occurred during his/her absence. A sleeve normally protects the narrow portion but slides easily away to expose the narrow portion when entry is desired.

A locking bar extends through the aperture of the locking plate and the hollow holding sleeve and into the aperture of the securing plate. A locking device is mounted onto the locking plate to securely hold the locking bar in place. When the locking bar is in place, movement of the door is prohibited and the door can not be opened.

  • Patent number: 4666106
    Abstract: A device for securing an opposing pair of outwardly opening cabin doors on general aviation aircraft and the like. A pair of non-extensible elongated elements, such as a pair of rods or a rod and a cable, are joined together at one end such that the elements can rotate independently of one another. The opposite ends of the elements are secured to the cabin doors, at least one of the elements being selectively engagable to its corresponding door from outside the aircraft. With the device in place, the cabin doors are clamped together and cannot be opened until at least one of the elements is disengaged from its corresponding door.

  • Patent number: 4639023
    Abstract: The locking bar assembly of the present invention is adapted to lock horizontally slidable, overlapping window doors, such as patio doors, in closed position. One end of a locking bar is pivoted to a bracket, or pivotal member, for movement in between a stored vertical position and a horizontal locking position. A clasping member, carried by the bracket, resiliently retains the locking bar either in the vertical position, or against upward pivoting from its horizontal position. The bracket is so constructed that it can be secured to the sash or to the handle flange of one door when the two doors can be opened, or to the door opening frame when only one door can be opened.

  • Patent number: 4455846
    Abstract: A locking device for securing the coin box of coin operated vending and amusement machines is provided. An elongated flat locking bar is pivotally connected to the face of the coin operated machine by means of a spring loaded pivot pin for swinging movement parallel to said face between a locking position extending across and in close juxtaposition to the access door of the coin box and an open position permitting access to said door. A locking pin extends through an opening in the free end of the locking bar and a corresponding opening formed in the face of the machine to a point on the interior of said machine adjacent to the coin box. A barrel lock normally provided to lock the access door of the coin box is fitted with a lever having a retaining notch formed therein which is adapted to engage the inner end of the locking pin in its locked position. Access to the barrel lock from the exterior of the coin operated machine is obtained by a suitable opening formed in the locking bar.

  • Patent number: 4261189
    Abstract: A retainer plate is pivotally mounted on a panelboard cabinet door lock housing, which carries a latch for locking the door. A detent on the plate engages in a rabbet opening to enable limited opening movement of the door in response to the pressure developed by arc gases generated by fault currents passing through a tripped circuit breaker in the panelboard cabinet. For ordinary opening movement, the lock latch is manually operated to pivot the retainer plate and disengage the detent from the rabbet opening.

  • Patent number: 4135376
    Abstract: A patio door or sliding window security bar which is of the type that is normally stored parallel to a frame member of the opening and movable to a horizontal position braced against the sliding panel frame or jamb so that the sliding panel cannot be moved to give access through the opening. A bolt is fully contained within the hollow bar end and capable of being reciprocated through the medium of a barrel or cylinder that is installed into the lateral wall of the bar to enable the bolt to be moved into a socket formed in the sliding panel frame to lock the bar against being swung upward or downward. A locking arrangement including a keyway enables the bar to be locked in horizontal position by means of a removable key to prevent unauthorized opening of the patio door even from the interior of the building having the opening.
