Musical pacifier

Claim 2

A musical pacifier comprising a mouthpiece having a nipple portion, a casing secured to said mouthpiece and housing an electronic programmed circuit capable of generating signals to produce a programmed sound, sound generating means associated with said circuit to audibly reproduce said signals, and switch means to actuate said circuit.

Claim 3

A musical pacifier as claimed in claim 1 wherein said mouthpiece has a mouth-guard to which said nipple element is secured, said housing being connected to said mouth-guard on a side thereof opposite to said nipple element.

Claim 4

A musical pacifier as claimed in claim 1 or 2 wherein said switch means is a mechanical switch secured to said casing and actuatable from an outside wall thereof whereby to switch said electronic programmed circuit to an "on" or "off" state.

Claim 5

A musical pacifier as claimed in claim 2 wherein said switch means is a switch contact element actuated by an air current which is generated by a displacement of air in a hollow space within said nipple element.

Claim 6

A musical pacifier as claimed in claim 4 wherein said nipple element has a securable open end which is secured in a bore in said mouth-guard by a hollow connector, said connector having passage means therein to form an air passage means therein to form an air passage from said hollow space within said nipple element to a space in which said switch contact is located.

Claim 7

A musical pacifier as claimed in claim 5 wherein said switch contact comprises a stationary contact and a displaceable contact, said displaceable contact having a free end portion extending into said space where there is created an air current by said nipple element, said air current causing said free end portion to flex and contact said stationary contact to effect a switch closure.

Claim 8

A musical pacifier as claimed in claim 6 wherein evacuation ports are communicated with said air passage to evacuate air from said passage when said hollow nipple element is collapsed and to admit air by suction created by said nipple element when restoring its initial shape after being compressed.

Claim 9

A musical pacifier as claimed in claim 4 wherein said housing is removably secured to said mouth-guard through a lock mechanism which is infant-proof and which houses said switch means, said casing and said lock mechanism being interconnected through a hinge joint, said casing being removable from said lock mechanism.

Claim 10

A musical pacifier as claimed in claim 8 wherein said lock mechanism comprises two cylindrical parts, one of said parts having at least two spaced apart posts extending diametrically outward of a cylindrical outer surface thereof, the other of said parts having at least two spaced apart channels corresponding to the spacing of said posts and disposed in an inner surface thereof to permit passage of said posts therein and to overlap a portion of said outer surface of said one part when advanced thereover, said channels having a locking end to receive an associated one of said posts therein against the pressure of spring means when said other part is rotated in a predetermined direction, said posts being retained at said locking end by said pressure.

Claim 11

A musical pacifier as claimed in claim 8 wherein said articulated joint is provided with electrical connectors.
