DESCRIPTION OF THE PREFERRED EMBODIMENT

Referring now to the drawings in greater detail, FIG. 1 shows a baby seat or chair having a back rest 1 which is attached to a seat portion 2 which in turn is attached to a support portion 3. It should be noted that the seat shown in FIG. 1 is merely illustrative of a baby seat, and other shapes could be used without departing from the scope of the present invention.

The support portion 3 has a horizontal portion 4 which is secured, in any conventional manner, to a support block 10, most of which has been removed from FIG. 1 for clarity. The support block 10 receives and supports the horizontal portion 4 in any conventional manner. The chair has a second horizontal portion 13 which fits into the support block 10, but is free to move with respect to the block. The top of the second horizontal portion 13 has a series of valleys 9 which form teeth 14 in between the valleys. In addition, the end of the second horizontal portion 13 has a stop 8 so the gear 6 can not move off the second horizontal portion 13. The chair has a second support portion 11 and a third horizontal portion 12 which form the rest of the support for the chair. A control knob 5 is mounted for rotation to the block 10 in any conventional manner. The knob 5 is connected to gear 6 so that when knob 5 is rotated, gear 6 will also rotate. Gear 6 engages the teeth 14 on the top of the second horizontal portion 13 so when knob 5 is turned in one direction the first horizontal portion 4 moves toward the right in FIG. 1. When knob 5 is turned in the opposite direction the first horizontal portion 4 moves toward the left in FIG. 1.

The portions 11, 12, 13 of the support stand are made from a springy material so the upper leg 13 will move up and down with respect to the lower leg 12. The adjustment mechanisms 5, 6, 9 and 14 are designed to compensate for different size babies. As shown in FIG. 1, the seat is adjusted to hold about a twenty pound baby. If the baby weighs more than twenty pounds, the adjustment mechanisms would be used to move the blocks 10 to the right in FIG. 1. Since the top leg 13 is essentially a cantilevered beam, this would reduce the moment arm of the beam making it more difficult for the leg 13 to move up and down. If the baby weighs less than twenty pounds, the adjustment mechanisms would be used to move the blocks 10 to the left in FIG. 1. Since the top leg 13 is essentially a cantilevered beam, this would increase the moment arm of the beam making it less difficult for the leg 13 to move up and down. Therefore, the adjustment mechanisms allow the present invention to be adjusted for virtually any size baby.

In order to move the upper leg 13 (and the seat secured to leg 13) up and down, a motor driven mechanism is attached to the back portion 1 of the seat by any conventional attachment means 26. A motor 27 is provided with a first wheel 26 that will be driven by the motor. The wheel 26 engages a second wheel 15 which rotates about a pivot point 25, so the wheel 27, driven by the motor 13, will cause wheel 15 to rotate. Wheel 15 has a weight 16 attached thereto by any conventional means. The weight 16 will throw the wheel 15 out of balance as it rotates, which will cause a vibration in attachment means 26, through seat 1, 2, 3, through block 10, and eventually into arm 13. Since the arm 13 is springy, the seat 1, 2, 3 will move up and down and, in so doing, will entertain a baby seated in the seat.

It should be noted that a framework will support motor 27, and wheels 26, 15, however it has been removed from FIG. 1 for clarity. Also, any motor can be used in the present invention including, but not limited to, an AC motor, a DC motor, a battery operated motor, or a motor operated by a mechanical means such as a spring.

FIGS. 2 and 3 show a different operating means for the seat of FIG. 1. Wheel 15′ (which is essentially wheel 15 in FIG. 1 without weight 16) has a cam 17 secured thereto which moves a follower 18 as the wheel 15′ rotates. The wheel 15′ is rotated by a motor (not shown in FIGS. 2, 3) like the motor 15 in FIG. 1. The follower 18 is connected to a beam 19, by any conventional means, which is pivoted at 23 on one end, and which has a weight 20 at the other end. As the cam 17 rotates from a down position, as shown in FIG. 2) to an up position (shown in FIG. 3) it moves the follower 18 which in turn pivots the beam 19 up. As the follower moves to the down position, the weight causes the beam 19 to move from the position shown in FIG. 3 to the position shown in FIG. 2, thereby causing the wheel 15′ to vibrate which will vibrate the seat 1, 2, 3.

FIGS. 4 and 5 show a different activation mechanism. Wheel 15″ (which is essentially wheel 15 in FIG. 1 without weight 16) has a solenoid 21 secured thereto by any conventional means. The solenoid 21 can be operated by the same motor 13 or it can be operated by a separate motor. The solenoid 21 moves a shaft 22 up (FIG. 5) and down (FIG. 4) as the solenoid 21 is turned on and off. The shaft 22 is secured to the wheel 15″ in a way so the wheel will move up and down with the shaft 22. In this way the wheel will vibrate which will cause the seat 1, 2, 3 to vibrate as in FIGS. 1, 2, 3. Once the wheel, which is essentially just a weight, is started up and down by the solenoid it will continue in an up and down motion for a while even after the solenoid is turned off.

FIGS. 6 and 7 show a different securing means for adjustably attaching the seat 1′″ to the springy legs 13′″ which are supported on legs 12′″ in the same manner as legs 13 and 12 in FIG. 1. A bar 24 is secured, in any conventional manner, to the seat. The bar 24 has apertures that receive the legs 13′″. A set screw 23 is threaded into the bars 24. In order to adjust the seat for different size babies, the set screw 23 will be loosened, the bar 24 will be moved to a new location, and then the set screw will be tightened to secure the bar in the new location. In all other respects, the device will operate in the same manner as the FIG. 1 device. It should be noted that the motor and wheels have been removed from FIGS. 6 and 7 for clarity.

Although the Baby Bouncer and the method of using the same according to the present invention has been described in the foregoing specification with considerable details, it is to be understood that modifications may be made to the invention which do not exceed the scope of the appended claims and modified forms of the present invention done by others skilled in the art to which the invention pertains will be considered infringements of this invention when those modified forms fall within the claimed scope of this invention.
