Abstract
Abstract A toy for a pseudo-medical kit, such as a make-believe reflex hammer, stethoscope, thermometer, sphygmomanometer or syringe, has a nonfunctional mobile part which resembles a functional element of the instrument simulated thereby and whose displacement or deformation produces a perceptible indication, such as the lighting of a lamp, a whistling sound, or the display or a numerical or pictorial reading.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
137 words
A toy for a pseudo-medical kit, designed to simulate a stethoscope, comprising: a cup resembling a stethoscope chest piece, said cup having a rim adapted to rest on an external object and further having an outwardly projecting tubular boss remote from said rim; a pair of earplugs connected to said cup via flexible links; a manually grippable sleeve slidably engaging said boss with freedom of limited relative displacement between an extended normal position and a compressed position, said sleeve being provided with a light-transmissive portion; spring means anchored to said boss and said sleeve for tending to maintain same in their normal relative position; and a signal lamp seated in said sleeve and provided with an energizing circuit closable for transluminating said light-transmissive portion upon displacement of said sleeve relative to said boss into said compressed position.
Claim 2
Dependent Claim
137 words
A toy for a pseudo-medical kit, designed to simulate a stethoscope, comprising: a cup resembling a stethoscope chest piece, said cup having a rim adapted to rest on an external object and further having an outwardly projecting tubular boss remote from said rim; a pair of earplugs connected to said cup via flexible links; a manually grippable sleeve slidably engaging said boss with freedom of limited relative displacement between an extended normal position and a compressed position, said sleeve being provided with a light-transmissive portion; spring means anchored to said boss and said sleeve for tending to maintain same in their normal relative position; and a signal lamp seated in said sleeve and provided with an energizing circuit closable for transluminating said light-transmissive portion upon displacement of said sleeve relative to said boss into said compressed position.
Claim 3
Dependent Claim
20 words
A toy as defined in claim 1 wherein said spring means comprises a conductive element included in said energizing circuit.
Claim 4
Dependent Claim
76 words
A toy as defined in claim 2 wherein said energizing circuit includes a battery with a pair of opposite terminals, said signal lamp being provided with a contact point confronting one of said terminals and with a base threaded into a socket, said conductive element having one end engaging said socket and another end engaging the other of said terminals, said one end tending to keep said contact point away from said one of said terminals.
Claim 5
Dependent Claim
23 words
A toy as defined in claim 2 or 3 wherein said conductive element forms a clip projecting into a cutout of said sleeve.
