ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a pattern forming cot, and more particularly to a baby head pattern forming cot.
2. Description of the Related Art
A conventional baby head pattern forming device in accordance with the prior art includes a cushion defining a recess whose shape is adapted to mate with that of the head of the baby so as to fix the baby's head, thereby achieving the purpose of forming a pattern on the baby's head.
However, the baby's head is fixed at a constant angle so that the inclined angle of the baby's head in the cushion is fixed and cannot be adjusted so that the forces are locally concentrated on a certain position of the baby's head, and cannot be distributed evenly, thereby easily deforming the baby's head during long term utilization, thereby decreasing the versatility of the baby head pattern forming device.
SUMMARY OF THE INVENTION
The present invention has arisen to mitigate and/or obviate the disadvantage of the conventional baby head pattern forming device.
In accordance with one aspect of the present invention, there is provided a baby head pattern forming cot comprising: a support base having two opposite side walls each defining a pivot hole; a rotary base rotatably mounted in the support base and defining a receiving chamber therein, the rotary base having two ends each provided with a pivot axle pivotally mounted in the pivot hole of a respective one of the two opposite side walls of the support base; a pattern forming base received in the receiving chamber of the rotary base and having a bottom with a shape mating with that of the receiving chamber, and a top defining a body-shaped recess and a head-shaped recess; and a rotation device mounted in the support base and including a motor secured in the support base, a drive gear mounted on and rotated by the motor, a rotation controller secured on the motor for controlling rotation of the drive gear, a reduction gear meshing with and rotated by the drive gear, and a driven gear secured on the pivot axle of one of the two ends of the rotary base and meshing with and rotated by the reduction gear.
In accordance with another aspect of the present invention, the baby head pattern forming cot further comprises a switch device mounted on the support base and including an angle set button and a time set button. The switch device connects with a positive/reverse rotation control circuit of the rotation controller of the motor.
In accordance with another aspect of the present invention, the switch device further includes a speed set button, and the motor is provided with a gear shift mechanism.
Further benefits and advantages of the present invention will become apparent after a careful reading of the detailed description with appropriate reference to the accompanying drawings.
