Abstract

A toy stethoscope including a flexible yoke with earpieces on the outer ends of the arms thereof, flexible tubes respectively extending along the arms from the earpieces to one end of a cylinder having a reciprocable plunger therein to produce sounds simulating natural heartbeats, another tube connected at one end to the other end of the cylinder and the other end of the tube being connected to a bellows element adapted to be manually operated to compress and release one end of the same to successively produce air pressure and suction operable upon the plunger to effect the sounds simulating natural heartbeats.

Claims

1. A toy to simulate a heartbeat and a stethoscope connected thereto to permit listening to said beat and comprising in combination, a double-ended bellows element closed at one end and the other end having an opening connected to one end of a flexible tube member, an open-ended cup-like member surrounding said one end of said tube and partially enclosing the end of the bellows connected to said tube, the closed end of said bellows, when expanded, projecting beyond the open end of said cup-like member to permit pressure against said bellows to compress it, a flexible yoke having earpieces respectively on the outer ends of the arms thereof, additional branch tube members interconnected to the other end of said flexible tube, and a sound-producing reciprocable member operable with a body interconnected in series with said tube members and actuated by operation of said bellows element to simulate the sound of a natural heartbeat.

2. The toy according to claim 1 in which said bellows element is formed of flexible material of self-restoring nature and accordian-like in shape and said closed end being adapted to be pushed against an object and then released to cause air pressure and suction consecutively produced by such movement to act upon said reciprocable member to effect said simulated sound of heartbeats.

3. The toy according to claim 1 in which the body within which said reciprocable member operates comprises a tubular sleeve within which said member is slidable between opposite ends of said sleeve to produce said simulated sound of heartbeats, the opposite ends of said sleeve respectively being connected to said tube members.

4. The toy according to claim 3 in which the other end of said flexible tube member is connected to one end of said tubular sleeve and said additional branch tube members having one end of each connected to the other end of said tubular sleeve and the other ends of said branch tube members respectively being connected to said ear pieces.
