Abstract
A musical door lock comprises a generally rectangular housing having enclosed therein door lock, an electric door bell and a battery chamber. When a push-button on the outer periphery is pressed to actuate a sound generator inside the housing, the combined electric door bell will release a musical melody or the sound of bird chirps inside the door. A second example provides a frequency regulator instead of a sound generator incorporated with a movable wireless door bell that offers more convenience to the house owners. In addition an anti-burglar device combine with the lock mechanism for releasing a warning signal which may be received by a portable radio receiver. This disclosure is characteristically providing an economical utility of space in a door lock as well as its variety of functions.
Claims5
A musical door lock comprising a generally rectangular housing having enclosed there in a door lock at an upper portion, an electric door bell at a middle portion and a battery chamber at a lower portion, wherein;
- said housing comprising an arched rectangular bottom portion, an encircled wall and an arched cover thereof;
- both of said bottom portion and said cover having equally formed outward flanges and a circular recess through said upper portion;
- a push-button disposed through said bottom portion and a speaker disposed on said cover in the proximity of a lid which is formed to cover said battery chamber thereof;
- said door lock comprising a tubular bar transverse and cross-extended through said circular recesses on the upper portion of said housing and indirectly connected to a spring door latch transversely extruded from said housing, and a pair of hand knobs secured on two ends of said tubular bar, each having a key aperture formed at the center of their outer peripheries;
- said electric door bell comprising sound generator connected respectively with said batter chamber, said push-button and said speaker;
- whereby said sound generator is actuated as said push button is pressed to release a musical melody or a sound of bird chirps through said speaker.
A musical door lock comprising a generally rectangular housing having enclosed therein a door lock at an upper portion, a frequency regulator at a middle portion, a battery chamber at a lower portion and a movable wireless door bell, wherein;
- said housing comprising an arched retangular bottom portion, an encircled wall an arched cover thereof;
- both of said bottom portion and said cover having equally formed outward flanges and a circular recess through said upper portion;
- a push-button disposed through said bottom portion, a lid formed to cover said battery chamber thereof;
- said door lock comprising a tubular bar transverse and cross-extended through said circular recesses on the upper portion of said housing and indirectly connected to a spring door latch transversely extended from said housing and a pair of hand knobs secured on two ends of said tubular bar each having a key aperture formed at the center of their outer peripheries;
- said frequency regulator disposed inside the middle portion of said housing being connected respectively with said battery chamber and said push-button;
- said movable wireless door bell having a generally rectangular casing comprising a frequency receiver, a sound generator, a transformer, a battery chamber, a speaker, a lid for covering said battery chamber, a light bulb secured in a tapering groove on a top incorporated with a sliding switch on a lateral periphery and a pair of plug blades on a back side of said casing;
- whereby said push-button outside a door is pressed to actuate said frequency regulator releasing a signal to be received by said frequency receiver inside said movable wireless door bell, a musical melody or bird chirps being accordingly released out by said sound generator through said speaker on an outer periphery of said casing.
