Abstract: Portable siren or emergency call device with a portable siren, comprising a loudspeaker (8), so as to emit an audio signal, preferably with a high sound pressure; an inner and/or outer switching element (14) for turning off and preferably for turning the audio signal on and off, and an outer switch and/or outer dummy switch (4).

Abstract: A personal alarm system for efficiently alerting individuals nearby that the user is possibly in danger. The personal alarm system includes a power source, a switch unit, and a speaker electronically connected to a control unit and positioned within an apparel member. A pin member is removably positioned within a receptacle of the switch unit with a cord member attached to the pin member. The cord member extends through an aperture within the apparel member for providing access thereto external of the apparel member. In the event of a perceived emergency, the wearer of the apparel member pulls upon the cord member thereby removing the pin member from the switch unit thereby causing the speaker to emit an audible warning sound.

Abstract: A portable anti-burglar device with optional fluid dispensing, alarm and fingerprint retention features is disclosed which when activated by the opening of a door or window or other violation of a secured aperture a spring biased actuating member operates to discharge a pre-packaged tear gas or identification fluid or other liquid dispersing canister and simultaneously close an electrical switch which is in series with another switch which controls the optional operation of an audible alarm when the device is activated regardless of whether a pressurized canister is in place. The device is portable and is coated with a wax or tar which can preserve fingerprints that may be deposited on the device by an intruder's attempt to deactivate it. The device is fitted with moveable mounting brackets which allow for a variety of mounting situations and also with a tamper resistant locking mechanism.

Abstract: A portable mechanical burglar alarm for monitoring doors and windows includes a base plate having a back surface provided with a plurality of suction cups for releasable securement adjacent a door or window. A pair of bells are secured in spaced relation on a front surface of the base plate and a pivotal oscillating clapper arm is disposed therebetween. A spring powered bell ringing mechanism is enclosed by a housing on a front surface of the base plate. A trigger mechanism within the housing is operative to actuate the bell ringing mechanism upon disengagement of an adjustable abutment stop member from contact with a door or window frame upon opening of the door or window. A retaining mechanism within the housing prevents unauthorized resetting of the trigger mechanism subsequent to activation, to prevent the ringing bells from being silenced.

Abstract: A passive air, gas aerosol or pressurized fluid activated personal self-protection screech alarm device that is armed prior to the person utilizing it entering into a potentially dangerous area or situation. The primary and radically different feature of this device from those currently patented and/or on the market is that no action is demanded of the person carrying it in the event of an attack other than the natural inclination to release ones grip. Releasing ones grip on the aerosol can and lever and dropping the device then activates an irrevocable screech alarm. This device plays to the psychological implications of attack in that if active, overt action is taken by the person who is the subject of a rape, for example, the attacker oftentimes becomes more violent. With this device, the natural inclination to show fright and drop whatever one is carrying serves to activate the alarm.

Abstract: A portable apparatus for use by a traveler whereby the traveler is able to protect himself from unauthorized entry through a preselected door and simultaneously protect himself from a fire occuring in the room where the portable apparatus is located.

Abstract: A portable defense device combining a flashlight with a renewable, interchangeable cylinder containing compressed gas which may be used to generate a noise, to disperse dye and/or an odoriferous spray. The compressed gas may be stored in a canister which may take the form of a spray can having the typical articulated dispensing nozzle which is then received in an articulated throat assembly displaced to release the contents by a pivoted trigger engaging a pivoted arm assembly. In the normal state the trigger is aligned over the exit opening of the throat, thus protecting the dispensing nozzle from inadvertent release, and when released the trigger aligns to engage the arm.

Abstract: A door alarm toy comprising a whistle adapted to be sounded by air escaping from an inflated balloon; and a clip adapted for engagement between a door and its door frame to hang the toy with an inflated balloon pressed against the door to frictionally retain a twist in the balloon which prevents it from deflating. When the door is then opened, the toy drops, the balloon untwists and air escaping from the balloon sounds the whistle.

Abstract: A portable alarm useful for indicating unauthorized entry at doors and windows includes a housing and a bell casing mounted in the housing with a clacker arm rotatably mounted within the casing and adapted to create an audible signal. A trigger arm is mounted within the housing, extending into to the bell casing and is biased against the clacker arm in a first direction. An actuator including an L-shaped arm and a pressure plate is pivotably mounted along an edge of the housing such that the lever arm extends outside the housing and with the pressure plate dimensioned so as to exert a pressure against the trigger arm in a second direction opposing the first direction responsive to a movement of the lever arm. The pressure plate is biased away from the trigger arm, until such time as a substantial force against the pressure plate overcomes the bias and forces the other end of the trigger arm out of engagement with the clacker arm, thereby effecting the audible signal.

Abstract: An auxiliary portable lock which comprises a housing, a lock body receivable within said housing, and adapted for axial rotation therein, said housing being internally communicative with a tubular casing axially normal to the longitudinal axis of said housing and being open at its opposite ends. There is an elongated locking bar having a serrated surface provided for extension through said tubular casing and having integrally formed at one of its ends, a door-engaging portion. A cooperative serrated member is provided within said housing for movement toward and away from the confronting portion of said locking bar for maintaining same in selected disposition; said cooperative serrated member is operatively engaged to said lock body which latter, through rotative movement effects translation of said cooperative serrated member. A door engaging element is formed at one end of said tubular casing. Key control components are provided to secure said lock body to said housing.
