A manhole includes a device for safely closing and locking the manhole, which has a cylinder with centering pins that is attached to a slab and is rotatable with an operating key acting on the pins, and further includes an anti-burglary block, which in locked position is positioned inside the cylinder and hides and protects an anti-theft bolt positioned inside a hole, which crosses the entire anti-burglary block and has a larger diameter at the front and the same diameter as the anti-theft bolt in the back, so as to receive the anti-theft bolt in a threaded spot in the inner wall of the cylinder and enable placement of the anti-theft bolt in the body of the anti-burglary block when totally tightened into the threaded spot, wherein the end of the anti-theft bolt, in closed position, is housed in a locking hole on a circular support of the cover.

A base member for a tablet computing device including a fastener to removably couple a tablet computing device to the base. A receptacle can receive a security lock to secure the base, wherein the security lock is to prevent the fastener from releasing the tablet computing device in a first mode and allows the releasing of the tablet computing device in a second mode.

A receptacle that can receive a cell phone or other mobile communication device or other useful objects such as keys that attaches over a restroom or changing room door latch used to secure the door during use of the restroom or changing room. Receptacle's position such that the usual insert a cell phone into the receptacle when the restroom stall door is secured closed and locked by a latch bolt. The user will not forget the cell phone because it will be necessary to remove the cell phone to access the latch bolt for unlocking the stall door. The device can also include advertising with DC and disposed on the receptacle surface or adjacent a portion of the receptacle surface. An ultraviolet light can be activated to help as a disinfectant device to kill bacteria and viruses on any cell phones or other objects in the receptacle.

A door lock assembly includes a door lock that is installed in a door of a building. The door lock includes a pair of door knobs and a latch bolt. The latch bolt engages a recess in a doorjamb when the door is closed for retaining the door in a closed position. Conversely, the latch bolt disengages the recess in the doorjamb when either of the door knobs is rotated thereby facilitating the door to be opened. A pin is extendable though the latch bolt of the door lock when the door is closed such that the pin abuts the door. In this way the latch bolt is inhibited from being urged into an unlocking position thereby inhibiting an intruder from defeating the door lock and opening the door.

The present invention is directed to a lock arrangement where a cylinder type lock with a skirt can be correctly positioned and orientated in a door latch by the use of complementary profiles that enable insertion in only one position and thereby provide ease of use and confirmation that the lock has been correctly inserted and locked.

An emergency shelter includes a number of reinforced walls that define a substantially enclosed interior space in which people can enter in emergencies; a doorway opening formed in at least one of the walls to permit entry into and exit from the interior space; a door mounted over that doorway opening; and a latching assembly for latching and locking the door in its closed position. The door is configured to slide horizontally relative to the doorway opening between an open position and a closed position so that it can be opened even when debris is blown up against it. The shelter also includes a door jamb adjacent the doorway opening for receiving and partially surrounding a leading edge of the door to prevent movement of the door along an axis transverse to the horizontal sliding direction of the door so that the door does not cave in when struck by debris. A flange on the trailing edge of the door overlaps a flange on the front wall when the door is closed to prevent movement of the door along an axis transverse to the horizontal sliding direction of the door so that the trailing edge of the door does not cave in when struck by debris. The latching assembly securely latches and locks the door in its closed position but permits the door to be opened even when portions of the latching assembly are damaged.
