Claim 14

An alarm device comprising: a hollow housing having at least one dimension having a generally circular shape so that the housing can be rolled, the housing being formed with a plurality of aperatures and the size of the housing being such that it can be conveniently carried within a hand; signal generating means mounted within said housing including an oscillator, a speaker and a battery; a switch connected to said signal generating means having a first position for inhibiting the signal generating means from operating and resilient means for switching the switch to a second position for causing the signal generating means to produce an alarm signal, and switch actuation means, including a detachable actuating unit extending through an aperature formed in the housing for the manual operation of the switch actuation means and engaging said switch overcoming said resilient means to switch said switch to the first position, and including means for providing a lock position for said actuating unit for preventing the operation of the signal generating means and a release position wherein the actuating unit, if unrestricted by manual force, springs away to separate from said housing thereby causing said actuation means to continuously operate said signal generating means.

Claim 15

An alarm device as defined in claim 12 wherein: said aperature receiving te actuating unit includes a keyway, and a portion of the actuating unit has the general shape of the keyway so that when the actuating unit is inserted into the keyway and is aligned with the keyway the actuating unit is in the release position and when the actuating unit is thereafter rotated beyond the keyway, the actuating unit is in the lock position.

Claim 16

An alarm device as defined in claim 13 including: additional resilient means coupled to said actuating unit so that when the actuating unit is inserted into the aperature including the keyway, the addition resilient means provides a force for urging said actuating unit out from said housing.

Claim 17

An alarm device comprising: a hollow housing having at least one dimension having a generally circular shape so that the housing can be rolled, the housing being formed with a plurality of aperatures, and the size of the housing being such that it can be conveniently carried within a hand; signal generating means mounted within said housing including a reservoir or pressurized gas, a valve for releasing gas from the reservoir, and a transducer responsive to gas flow from said valve and through the transducer to produce an alarm signal, and alarm actuating means contained within the housing for controlling the operation of said valve, including a detachable actuating unit extending from said housing for manual operation of the alarm ectuation means, resilient means, and receiving means for providing a lock position for said actuating unit for preventing the operation of said signal generating means and providing a releaSe position wherein the actuating unit, if unrestricted by manual force, springs away under the force of said resilient means to separate from said housing causing said actuation means to continuously operate the signal generating means.
