Abstract
A door securing device with an elongated, rigid bar that is attachable to a pair of lock posts affixed to the door or door frame of the building or other secured area to be protected against unwanted entry. The bar has an opening in each of its ends, each for receiving one of the lock posts. The first lock post has a groove therein in which the bar slides within the constraints of the opening corresponding with that post. The second lock post has a narrow neck which receives the bar via the corresponding opening therein, and an enlarged base which receives and locks the bar in place when the bar is axially slid along the post thereby allowing a lock to be closed over the narrow neck to secure the door of the building.
Claims19
A door latch for securing an access door into a secured area against unwanted entry, said door securing device comprising:
- an elongated, rigid bar having first and second openings therein;
- a first lock post insertable in the first opening and selectively securable therein;
- and
- a second lock post insertable in the second opening and including a pad lock receiving groove circumferentially therearound for selectively securing the elongated, rigid bar to the second lock post.
A door securing device for securing an access door into a secured area against unwanted entry, said door securing device comprising:
- an elongated, rigid bar having first and second ends:
- a slot formed in the elongated, rigid bar adjacent one of the first and second ends;
- a first lock post including an enlarged head thereon;
- first connecting means for connecting and subsequently slidably engaging the first lock post to the elongated, rigid bar;
- a second lock post including a circumferential groove for receiving a lock;
- and
- second connecting means for connecting the second lock post to the elongated, rigid bar.
A method of securing an access door into a secured area against unwanted entry, said method comprising:
- locking a first end of an elongated, rigid bar to a first lock post affixed to a boundary defining a secured area;
- positioning a second end of the elongated, rigid bar so that a narrow gap formed in the second end of the elongated, rigid bar slips over a groove on a second lock post resulting in the second end of the rigid bar resting on the second lock post in a hole in the second end of the elongated, rigid bar;
- sliding the hole over a collar on the second lock post of larger cross-section than both the gap and the groove;
- and
- locking a pad lock in the groove on the second lock post.
