Abstract
Abstract An electrically actuated and remotely controllable toy transporter for vehicles which comprises, in combination, a tractor trailer unit, a trailer adapted to travel with, or trail behind, the tractor trailer unit, and a manually operable electric remote-control device for remotely controlling the tractor and/or the trailer. One of the principal features of the present toy consists in that the trailer can be hooked up with and unhooked from the tractor by manipulation of the remotecontrol device. Also, another principal feature is that the trailer is equipped with electrically actuated and remotely controllable means for loading and unloading the vehicles.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
265 words
A remotely controllable toy transporter for vehicles comprising, in combination, a powered tractor trailer unit comprising a unit body having at a portion adjacent to the rear end thereof first coupling means with a pair of electric contacts, a trailer adapted to travel with said tractor and comprising a trailer body having therein a reversible motor and having at a portion adjacent to the front end thereof second coupling means adapted to be releasably engaged with the first coupling means, said trailer body also having in close proximity to said second coupling means a pair of electric contacts connected in circuit with said reversible motor and adapted to be brought into contact with the first-mentioned contacts, a manually operable remote-control device electrically connected to the first-mentioned contacts through flexible connecting leads so that when the two pairs of contacts are brought into contact with each other the motor circuit is formed, said trailer further comprising a rotatable supporting wheel assembly including a pair of transversely spaced rotatable supports rotatable about a horizontal axis within a predetermined angular range and being arranged to be brought into operaTive connection with the reversible motor for pivotal movement when the latter is rotated in one rotational direction, whereby when the motor is rotated in that direction by manipulation of said remote-control device during the contact of the first-mentioned contacts with the second-mentioned contacts, the forward portion of the trailer body is caused to be raised and lowered by said supporting wheel assembly, thus permitting the first and second coupling means to be coupled with and uncoupled from each other.
Claim 2
Dependent Claim
265 words
A remotely controllable toy transporter for vehicles comprising, in combination, a powered tractor trailer unit comprising a unit body having at a portion adjacent to the rear end thereof first coupling means with a pair of electric contacts, a trailer adapted to travel with said tractor and comprising a trailer body having therein a reversible motor and having at a portion adjacent to the front end thereof second coupling means adapted to be releasably engaged with the first coupling means, said trailer body also having in close proximity to said second coupling means a pair of electric contacts connected in circuit with said reversible motor and adapted to be brought into contact with the first-mentioned contacts, a manually operable remote-control device electrically connected to the first-mentioned contacts through flexible connecting leads so that when the two pairs of contacts are brought into contact with each other the motor circuit is formed, said trailer further comprising a rotatable supporting wheel assembly including a pair of transversely spaced rotatable supports rotatable about a horizontal axis within a predetermined angular range and being arranged to be brought into operaTive connection with the reversible motor for pivotal movement when the latter is rotated in one rotational direction, whereby when the motor is rotated in that direction by manipulation of said remote-control device during the contact of the first-mentioned contacts with the second-mentioned contacts, the forward portion of the trailer body is caused to be raised and lowered by said supporting wheel assembly, thus permitting the first and second coupling means to be coupled with and uncoupled from each other.
Claim 3
Dependent Claim
91 words
A remotely controllable toy transporter as set forth in claim 1, wherein said trailer further comprises a top ramp for carrying vehicles, a pair of transversely spaced supports projecting upwardly from the trailer body and pivotally supporting the top ramp, a mechanism operatively connected with the top ramp for operation thereby to impart pivotal movement to the top ramp, said mechanism being arranged to be brought into operative connection with the reversible motor for operation when the latter is rotated in the other rotational direction by manipulation of the remote-control device.
Claim 4
Dependent Claim
89 words
A remotely controllable toy transporter as set forth in claim 2, wherein said trailer still further comprises a tale gate for permitting the vehicles to be loaded and unloaded, said tale gate being pivotally attached to the rear end of the trailer body so as to be rotatable about a horizontal axis and being operatively connected to the mechanism for imparting the pivotal movement to the top ramp, whereby when said mechanism is operated the tale gate is arranged to be imparted pivotal movement synchronously with said top ramp.
Claim 5
Dependent Claim
70 words
A remotely controllable toy transporter as set forth in claim 3, wherein the tale gate is formed with means for securely holding the top ramp at a certain height, said holding means being arranged to be engaged with the rear end of the top ramp when the tale gate assumes a substantially upright position by being rotated and the top ramp is raised to a certain height by being rotated.
Claim 6
Dependent Claim
92 words
A remotely controllable toy transporter as set forth in claim 1, wherein the tractor trailer unit further comprises a reversible motor disposed within its body and electrically connected to the remote-control device through connecting leads, a driving wheel assembly on said body and a gear arrangement disposed within said body and operatively connecting the reversible motor with the driving wheel assembly, whereby when the motor is selectively rotated in one rotational direction or the other by manipulation of the remote-control device the tractor trailer unit is caused to travel forward or backward.
Claim 7
Dependent Claim
114 words
A remotely controllable toy transporter as set forth in claim 1, wherein the tractor trailer unit further comprises a reversible motor disposed within its body and electrically connected to the remote-control device through connecting leads, a steering mechanism mounted in said body and a gear arrangement disposed within said body and operatively connecting the motor with the steering mechanism, said steering mechanism being arranged to steer the tractor trailer unit either right or left according to the direction of rotation of said motor, whereby when the motor is selectively rotated in one rotational direction or the other by manipulation of the remote-control device the tractor trailer unit is caused to travel right or left.
Claim 8
Dependent Claim
62 words
A remotely controllable toy transporter as set forth in claim 2, wherein the manually operable remote-control device includes two push-button switches for actuating the reversible motor, one of said switches being operative for causing a polarity reversal of the current supplied to the motor, whereby when the push-button of the switch is depressed the direction of rotation of the motor is reversed.
Claim 9
Dependent Claim
85 words
A remotely controllable toy transporter as set forth in claim 5, wherein the manually operable remote-control device includes two push-button switches in circuit with the reversible motor for driving the tractor trailer unit forwaRd and backward, one of said switches being operative for causing a polarity reversal of the current supplied to said motor, whereby when the push-buttons of the switches are alternately depressed the direction of rotation of said motor is alternately changed to cause the running direction of said tractor to be reversed.
Claim 10
Dependent Claim
84 words
A remotely controllable toy transporter as set forth in claim 6, wherein the manually operable remote-control device includes two push-button switches in circuit with the reversible motor for operating the steering mechanism, one of said switches being operative for causing a polarity reversal of the current supplied to said motor, whereby when the push-buttons of the switches are alternately depressed the direction of rotation of said motor is alternately changed to cause the running direction of said tractor to be changed right and left.
