ABSTRACT:
BACKGROUND OF INVENTION
The field of the invention has various means to increase the security of closures such as cabinet doors against unauthorized openings and the give clear visual indication of any unauthorized movement. It is conventional practice to provide the cabinet of its individual closures with a key or combination lock option. The typical drawbacks of having a unlockable cabinet is tampering without observable signs of unauthorized entry . This present invention has simplicity, ease of use, convenience and visibility of its security. It has a simple design and is easy to apply to cabinets.
SUMMARY OF THE INVENTION
The objective of the invention is to produce a simple inexpensive locking device for hinged cabinet glass doors having no frame to hold a lock. The present invention is directed to security devices and more particularly to an improved hasp construction for use in releasably securing a pair of adjacent door closures in closed condition relative to a closure bounding cabinet's glass doors. The present hasp being equally adapted for used with closures in the form of swinging doors. For cases given wherein less than all of the closures of any given cabinet are required to be afforded extra security if needed with this present invention intended to be secured to an associated cabinet by mounting to the base of the closure and releasably secured shut by means of a padlock or similar.
Another object is to provide a latch construction which is simple, has few parts and is economical and easy to manufacture, yet durable and cannot jam or otherwise readily become inoperable. Still further objective is to provide such a door latch which can be installed easily and quickly by an unskilled person using common tools.
The Glasp would most likely be made from a suitable metal such as stainless steel or brass and would come in the form of two main components. The metal used in each would have thickness of about ⅛″. One component would be a rigid “L” (back plate) shape piece about 2 inches high by 1 ½ inches long and one inch wide. The “L” (back plate) shaped piece has slotted holes for adjustment to glass doors of various thickness. The other component of the “Glasp” would have two flat hinge pieces with corresponding holes to match the “L” shaped back plate which is the base design of this apparatus.
This apparatus was invented to fulfill the need for a way to secure the hinged unframed glass doors of a display cabinet or similar item. This invention has simplicity, ease of use, convenience and security. Once installed, however, it would provide a convenient way for a person to secure a display cabinet, etc. The user could easily lock and unlock the cabinet as desired and the product would not interfere with normal opening and closing of the doors in any way.
