Abstract

Improved toy telephone, which is constituted by a pair of battery-operated telephone sets with their corresponding handsets equipped with an earphone and microphone, communicated with each other by a bipolar cable, and comprising respectively acoustic and optical signaling devices for intercommunication, is essentially characterized in that the housing of each telephone set is constituted by a rectangular body with curved-convex sides, whose upper face is slightly inclined, with a slope to one of the larger sides, said upper face having at its ends paths concavities that establish the support for the body of the handset, in longitudinal arrangement, while one of said concavities has in its bottom a slot through which emerges the upper edge of a vertical laminar body, whose lower edge determines a tongue and vertical pivots that they constitute guides of displacement or of said laminar body, the pivots penetrating in two axial steps of emerging cylinders of an inner connection plate and inferiorly coupled to the housing; said tab of the vertical laminar body resting on the end of a strap constituting a movable contact interposed between two other fixed contacts of parallel ends, said movable contact comprising said elastic tendency of connection with the upper fixed contact, while the weight of the handset causes the disconnection of the upper contact and establishes it with the lower contact, said contact set constituting the switch between the signaling and hearing circuits; while the upper face of the housing of each telephone apparatus centrally presents the grouping of keys that limit the selector-marker device, each of whose keys emerging through windows of said housing, are coupled to an internal support by means of respective pins parallels finished off on harpoon tips, lascuales pass through rectangular windows of the upper plate of the support, being interposed between the latter and each key an expansion spring housed partially in the cavity of each key, keeping them raised against the stop posed by the tips of the harpoon of its temples, snapped on the edges of the windows of said support plate; further comprising said housing of each telephone set, on each side of the key cluster of the simulated marker-selector, a pushbutton and a transparent viewer of the light source, respectively, whose pushbutton is constituted by an elongated cylindrical body, with a projection will annul in the central region of its body that supposes a stop of elevation against the casing, its end of the contact spring constituting the switch of the feeding circuit of the buzzer and light source of the opposite telephone apparatus, so that the pick-up of one of the handsets and the actuation of their pushbutton, cause acoustic and optical signaling on the opposite telephone, while the pick-up of the second handset causes the serial supply of both handsets; being the keys of the selector-marker simulated, inactive with respect to the electrical system.
