 Alarm device with door/window cross-bar

Details
Inventors: Neas, Traci L.;
Assignee:
Primary Examiner: Hofsass; Jeffery A.
Assistant Examiner: Woods; Davetta
Attorney, Agent or Firm: Breaux; Joseph N.

An alarm device with cross-bar that includes a telescoping cross-bar having a spring tensioning mechanism; an alarming circuit having a pair of contact points extending out from a contact point end of the cross bar; and a contact bracket, sized to detachably hold the contact point end of the cross-bar, having a moveable contact plate constructed from an electrically conductive material provided thereon in a manner such that both of the contact points of the alarm circuit contact the moveable contact plate when the contact end of the cross-bar is held by the contact bracket. The moveable contact plate is preferably pivotally supported from a central point. In a preferred embodiment the alarm circuit of the alarm device further includes a key-strip upon which a preselected deactivation code must be entered to turn off the alarm device after activation of the audible alarm.

DETAILED DESCRIPTION What is claimed is: 1.
An alarm device with door/window cross-bar comprising: a telescoping cross-bar having a spring tensioning mechanism; an alarming circuit having a pair of contact points extending out from a contact point end of said cross bar and an audible alarm; and a contact bracket, sized to detachably hold a contact point end of said cross-bar, having a moveable contact plate constructed from an electrically conductive material provided thereon in a manner such that both of said contact points of said alarm circuit contact said moveable contact plate when said contact end of said cross-bar is held by said contact bracket; said moveable contact plate being pivotally supported from a central point.
2.
An alarm device with door/window cross-bar comprising: a telescoping cross-bar having a spring tensioning mechanism; an alarming circuit having a pair of contact points extending out from a contact point end of said cross bar and an audible alarm; and a contact bracket, sized to detachably hold a contact point end of said cross-bar, having a moveable contact plate constructed from an electrically conductive material provided thereon in a manner such that both of said contact points of said alarm circuit contact said moveable contact plate when said contact end of said cross-bar is held by said contact bracket; said contact bracket having a bracket portion that a half cylindrical shaped contact end receiving cavity sized to receive and hold said contact end therein, and a central contact plate support that extends into said contact end receiving cavity and supports said contact plate in a manner such that said contact plate is free to pivot freely, said central contact plate support having a retaining tab formed at an end thereof that retains said contact plate on said contact plate support.
3.
The alarm device with door/window cross-bar of claim 1, wherein: said alarm circuit includes a key-strip upon which a preselected deactivation code must be entered to turn off said alarm device after activation of said audible alarm
