Abstract
ABSTRACT OF THE DISCLOSURE
A bag alarm device utilizes a bar slideably affixed to the interior surface of a closure flap of a handbag extending outwardly from the marginal edge thereof. A pair of electrical contacts are urged into a closed position when the free end of the bar is pulled outwardly from the marginal edge of the flap by unauthorized means other than releasing the free end of the bar from locking engagement with a lock secured to the body of the bag. Closure of the contacts is maintained until the bar is permitted to return to its normal unextended position following opening the lock and releasing the bar in a an authori-zed manner. An alarm device, including audible and visual alarms, is energized by a battery carried by the bag when the contacts are in the closed position.

The Tuccl apparatus however, requlre~ the u~er to purposerully hut of~ the alarm on each occa~lon that the b~g 1~ to be opened in an authorlzed Danner.
It is an object of the present invention to provide a new and improved bag alarm device.
Most bags of good quality are provided with locks in one form or another. The locks may be of the combination variety, key operated variety, or a simple twist cam lock amongst others.
Common to each of the most popular locks is a bar which extends from the flap closure of the bag adapted to be releasably secured to the body of the bag by the lock mechanism. The present invention provides an apparatus which senses a substantial pull-like force being exerted upon the bar when an attempt is made to open the bag by means other than releasing the bar from the lock mechanism ln an authorized manner. Be retaining the bar in its "pulled"
position, the alarm will continue to sound, or visibly signal, until such time that the bag is opened in an authorized fashion and the bar is permitted to return to its normal "unpulled"
position.
~ccording to the present invention there is provided a bag alarm device comprising means mounted on said bag to provide a source of direct current, alarm means mounted on said bag and electrically connected to said direct current means, pull responsive switch means mounted on a closure flap of said bag, said pull responsive switch means having an elongated external component having a longitudinal axis, said component extending outwardly from said closure flap, a portion of said external component releasably locked with a lock secured to a surface portion of the outside surface of said bag when said closure flap is overlying said surface portion thereby maintaining said bag in a closed condition, a set of contacts being maintained in an open circuited condition when said portion is locked with said lock, said set of contacts being disposed in a closed circuited condition upon the application of a pulling force applied to said closure flap in a direction of tne longitudinal axis of said component tending to dispose said portion of said component further outwardly from said closure flap whilst said portion of said component is maintained locked with .
said lock, means to releasably maintain sai.d set of contacts in.
said closed circuited condition following said application of v said force, means to unlock said lock, releasing said porti.ontherefrom without disposing said set of contacts into said closed circuited condition, said set of contacts connected to sai.d alarm means.
A specific embodiment of the invention is illustrated in the accompanying drawings in which:
Figure 1 is a perspective view of the present invention.
shown Mounted to a closed bag.
Figure 2 is a perspective view of the present invention illustrating the ~ag, shown in Figure 1, in an. opened condition.
Figure 3 is a schematic diagrarn of the electrical components utilized in the present invention.
The structure and method oi iabricatlon oi the present lnventlon 18 applicable to a bar having a sub6tantially T-shape wbose leg 18 adapted to sllde wlthln a cavlty iormed by 8 U-shaped brac~et secured adJacent a msrglnal edge to the lnternsl surince oi a closure il8p oi a bag. The "cap" oi the T prohlblts the bar irom unllmlted extenslon ln the dlrection outwardly irom the marglnal edge oi the ilap. A hellcal sprlng urge~ the bar 80 that the iree end oi the bar ls pulled towards the marglnal edge oi the il8p. One marglnal edge oi the leg oi the bar 18 serrated such that the serratlons are engaged by the cam-llXe end oi a pawl sprlng blased lnwardly toward the serratlons. The other end oi the pawl ls iitted wlth an ar~ whlch when manlpu-lated per~lts the cam-llke end oi the pawl to dlsengsge irom the serratlons. The pawl 18 plvotably secured, intermedlate lts ends to the lnterlor surface oi the ilap. Thus, the bar can be maln-talned ln a normal extended posltlon by the pawl engaglng oDe serr~tlon and urged lnto a locklng pO8~ tlon by the actlon oi the sprlng on tbe bar. The bar mar be pulled outwardly irom the ~arElnal edge oi the flap causlng the pawl to engage another serratlon, locklng the bar ln the super extended posltlon.
