(Cl. 2741) ABSTRACT OF DISCLOSURE A toy record player for playing back sound recorded on a rotatably and axially mounted turntable which is spring-biased against the stylus arm of the record player which in turn is biased into sound-transmitting contact with a loudspeaker cone. Means are provided for releasably retaining the stylus arm in an OFF position separated from the sound track to prevent damage to the sound track and the stylus arm when the player is not in use. In addition, safety means are provided which are movable between the OFF position in which the sound track on the turntable, the stylus arm and the loudspeaker cone are held in tight mutual engagement and the ON position in which the sound track on the turntable, the stylus arm and the loudspeaker cone are held in yieldable soundtransmitting engagement. These safety means permit storage shipment of the record player in any position without danger to the components of the record player. More over, the safety means when in the OFF position disconnect the battery of the record player thereby preventing drainage on the same.

The present invention relates to a toy record player for playback from a spiral-shaped grooved sound track on a carrier, and more particularly to an electrically operated toy record player suitable for incorporation into a toy body, such as a doll, a toy animal, etc.

It is an object of the invention to provide a novel and improved toy record player of the general kind above referred to which is capable of playing in any position of tilt.

It is also an object of the invention to provide a novel and improved toy record player of the general kind above referred to, the stylus or needle of which is automatically disengaged from the sound track upon playback of the message recorded on the track and is firmly held in its disengaged position so that the record player can be shipped and stored in any position of tilt without danger of damage.

Another object of the invention is to provide a novel and improved toy record player including a safety means operable for disconnecting the battery for rotating the turntable and for substantially immobilizing the stylus of the record player when the same is not in use, to prevent drain on the battery and damage to the stylus or the sound track due to the normal handling of a toy enclosing the record player, said safety means being operable from the outside of the toy.

A further object of the invention is to provide a novel and improved toy record player which is capable of repeating, partly or completely, a message recorded on the sound track by simply operating an actuating member accessible from the outside of the toy in which the record player is enclosed.

A still further object of the invention is to provide a novel and improved toy record player which is compact, sturdy and inexpensive to manufacture, and the operation of which does not require skill or dexterity beyond the capabilities of a young child.

Other and further objects, features and advantages of the invention will be pointed out hereinafter and set forth 3,401,942 Patented Sept. 17, 1968 in the appended claims constituting part of the application.

In the accompanying drawing, a preferred embodiment of the invention is shown by way of illustration, and not by way of limitation.

In the drawing:

FIG. 1 is an elevational front view of a toy record player according to the invention;

FIG. 2 is a sectional view taken on line 2-2 of FIG.

FIG. 3 is a rear elevational view of the record player;

FIG. 4 is a front elevational view of the record player, part of the assembly being removed for the sake of clarity of illustration;

FIGS. 5 through 8 are diagrammatic illustrations of the mechanism of the record player showing the mechanism in several operational stages; and

FIG. 9 is a circuit diagram of the record player.

Referring now to the figures in detail, the exemplified toy record player comprises a housing 10 composed of a front assembly 11 and a rear assembly 12. The two assemblies are detachably secured to each other by means of suitable fastening means, such as screws and nuts, inserted into holes 13. These holes and additional holes 14 may be used for mounting the record player within a toy for which sound capability is desired, such as .a doll, an animal, a robot, a railroad station, etc.

The record player further comprises a turntable 15 which supports a sound track 16. The sound track is a conventional spiral-shaped sound track of the groove type. The track may be either cut directly into one side of the turntable, or a record disk on which the track is recorded may be fixedly or detachably secured to the turntable for rotation in unison therewith. The shaft 15a of the turntable is rotatably and axially displaceably supported in wall portions 17 and 13 of the housing. The turntable has a peripheral groove 19 in which is fitted a transmission member, such as a belt 20, by means of which the turntable is coupled to the drive shaft 21a of an electric motor 21. A stylus arm 25 mounting a stylus 26. The arm is secured to an arbor 27 which is rotatably and axially displaceably supported by housing wall 18. A cut-out 28 in housing wall 18 permits a pivotal movement of the stylus arm between a first angular position in which stylus 26 is engageable with the beginning of sound track 16 at the outer end thereof and a second angular position in which the stylus is off the inner end of the sound track adjacent thereto, as can best be seen in FIG. 1.

A first axially acting spring 30 biases the stylus arm 25 in the direction toward engagement with sound track .16 on the turntable by means of a collar 25a on the arbor 27 for the stylus. A second rotationally acting spring 31 biases the stylus arm toward its first angular position; that is, into the position in which the stylus is positioned to begin playback. A third axially acting spring 32, which at one end abuts against a housing wall portion 33 and at the other end against turntable 15, biases the latter toward the stylus; that is, into a position in which the stylus and the sound track are in coacting engagement.

The turntable includes a preferably annular recess 15b into which the stylus drops by the combined action of springs 30 and 32 when it passes beyond the inner end of sound track 16, for a purpose which will be more fully explained hereinafter.

The end of the stylus arm coacts with a mechanical amplifier 34, shown as a cone. This cone is peripherally held on a wall portion of housing part 11 by means of a corrugated flexible ring 34a. The stylus arm is engageable with the apex of the cone. To assure that the arm remains in engagement with the apex of the cone for the entire pivotal movement of the arm between the beginning and the end of the sound track, the stylus arm terminates in a cross-head-shaped portion 250.

The record player further comprises an actuating means shown as a bellcrank lever 35. This lever is pivotal about a pivot axis 36. Arm 35a of the lever is engageable with turntable shaft 15a to effect an axial displacement of the turntable, for a purpose which will be more fully explained hereinafter, and the other arm 35b, serves to pivot lever 35 about its axis 36. Pivoting of the lever may be eifected manually or by a remote control means, such as a Bowden cable, A mounting eye 350 is provided to connect such cable. Arm 35b of the lever, whether actuated directly or by remote control, should be so placed that it is accessible from the outside of the toy body in which the record player is enclosed. A spring 40 biases lever 35 into the position shown in FIG. 2 in which lever arm 35a is separated from the respective end of turntable shaft 15a.

The toy record player also includes a safety means 50, shown as comprising a lever 51 pivotal about a pin 52 secured to housing wall portion 17. A handle or grip 53 may be provided to facilitate manipulation of lever 51. The lever is pivotal between two positions, marked ON and OFF in FIG. 3. In the OFF position the lever is disengaged from the respective end of turntable shaft 15a, but in the ON position the lever abuts against the end of the shaft, thereby preventing axial displacement of the turntable toward the right as seen in FIG. 2, displacement toward the left being impeded by stylus arm 25 loaded by spring 30.

The energizing circuit for motor 21 is controlled by two switches. One of the switches, to wit, switch S5, is normally closed. It comprises a stationary contact 56 and a movable contact 57. The latter contact is controllable by the axial movement of turntable 15. The second switch is formed by lever 51, which is wired into the energizing circuit, as is indicated at 58, and a contact button 59 engaged by lever 51 when the same is in its OFF position. The lever rests in its ON position on a button 60 connected to motor 21. As is evident from the circuit diagram of FIG. 9, the motor is connected to a battery 61 as the source of current when both switches are closed.

The toy record player as hereinbefore described will now be explained in connection with FIGS. through 8.

FIG. 5 shows the same operational condition of the record player as is shown in FIG. 2, but in a diagrammatic fashion. The stylus 26 is in the position for the beginning of a playback; that is, it is engaged with the sound track at the beginning thereof. The stylus arm is in sound-transmitting engagement with the apex of cone 34. Lever 51 is in the position of FIG. 2 or FIG. 3; that is, in its OFF position, which constitutes a safety position !for the device. Accordingly, the switch contact represented by lever 51 is disengaged from second switch contact 59. Hence the energizing circuit of motor 21 is open. Arm 51 neutralizes the action of spring 32 by pressing the turntable into an axial position in which stylus arm 25 and stylus 26 thereon are wedged between the stationary abutment formed by the apex of cone 34 and the turntable. As a result, the stylus arm will not easily move in reference to the turntable, and more specifically, the sound track thereon, when the record player is shipped or stored in an upside down or sidewise position, and also when the record player is moved into a variety of positions of tilt during normal handling of the toy body in which the record player is enclosed.

It should be understood that the stylus arm and the stylus thereon are not positively secured in the described and illustrated position due to the presence of springs 30 and 31, but the retention of the stylus arm is firm enough for all practical purposes to prevent damage to the record player.

To start the record player, lever 51 is placed in the ON position of FIG. 3. As a result, the motor circuit is closed via contact button 60, and the motor will begin to spin the turntable. The recorded message will now be played back, cone 34 responding linearly by reason of the yielding at its accordion suspension formed by corrugated ring 34a.

The playing position is illustrated in FIG. 6.

As the stylus reaches and passes the inner end of the sound track, it will drop into recess 15b. Spring 32 will push the turntable upwardly, whereby spring contacts 56 and 57 become disengaged. As a result, the motor circuit is interrupted, and the turntable comes to a standstill. This operational condition of the record player is shown in FIG. 7.

In order to repeat playback of the message, lever 35 is pivoted from the position of FIGS. 5, 6 or 7 into the position of FIG. 8. Such pivoting of lever 35 depresses turntable 15 against the action of spring 32. As a result, switch contacts 56 and 57 will re-close and stylus 26 is clear of recess 15b and will be snapped back into the position of FIG. 5 by the action of spring 31. As soon as this is accomplished, lever 35 is released. Turntable 15 will be lifted by the action of spring 32 into the position in which the sound track thereon is in engagement with stylus 26. All the components are now returned to the position of FIG. 5, and the repeat of the playback of the message will begin.

As is evident, lever 35 may be released before the stylus arm has fully returned into its initial position in the event it is desired to repeat only part of the recorded message.
