System to move objects in a circle

Abstract

A system to enable an object to move in a circular motion while keeping an upright position of the object intact includes a base, and a motor disposed on the base. The system further includes an enclosure configured to be attached to the motor, and a bearing wheel attached to the enclosure. The system additionally includes an up arm attached to the bearing wheel, and a holding arm attached to the up arm. The holding arm includes an attachment point to which the object is configured to be attached. The motor is configured to move the object in the circular motion by causing the up arm and the holding arm to move in the circular motion when the motor is switched ON.

(8) Reference will now be made in detail to the present preferred embodiments of the invention, examples of which are illustrated in the accompanying drawings. Wherever possible, the same reference numerals are used in the drawings and the description to refer to the same or like parts.

(9) FIG. 1 depicts a perspective view of a system to move an object in a circle in accordance with embodiments of the invention. FIG. 1 will be described in conjunction with FIGS. 2-5. Specifically, FIG. 2 depicts an exploded view of the system of FIG. 1, and FIG. 3 depicts a section view of the system taken along line 3-3 in FIG. 1. Further, FIG. 4 depicts a side view of the system of FIG. 1 showing vertical movement, and FIG. 5 depicts a top view of the system of FIG. 1 showing side-to-side movement.

(10) The system may be configured to enable an object to move in a circular motion (or in a circle) while keeping the object's vertical or upright position intact. Any object may be firmly fixed or attached to the system without any extra mechanical gear or motors. A user may simply screw or attach the object to the main axis of the system, and the system maintains the object's upright position while moving the object in a circle (in any direction, e.g., a clockwise direction or a counterclockwise direction). In some cases, the base may be fixed to a flat surface with two points of contact.

(11) The system may include a base 10 on which a lower bearing 12 may be attached/affixed. In an exemplary aspect, the lower bearing 12 may be circular in shape. In some aspects, a bottom portion of the lower bearing 12 may be attached to the base 10, and a top portion of the lower bearing 12 may be attached to a yoke 14. The yoke 14 may have U-shaped structure (as shown in FIGS. 1 and 2), and a lower portion/part of the yoke 14 may be attached to the top portion of the lower bearing 12.

(12) Left and right walls of the U-shaped yoke 14 may include or be attached with bearing yokes 16. In some aspects, the bearing yokes 16 may be disposed on the external surfaces of the left and right walls of the yoke 14. In the exemplary aspect depicted in FIG. 2, the bearing yokes 16 are attached to the left and right walls of the yoke 14 via bolts 18 and nuts 20. In some aspects, the nuts 20 may be disposed on the interior surfaces of the left and right walls of the yoke 14.

(13) The system may further include a motor 22 that may be disposed on the base 10, at a predefined distance away from the yoke 14. The motor 22 may be any motor, e.g., a Direct Current (DC) motor, an Alternating Current (AC) motor, a stepper motor, a servo motor, etc. A proximal end of the motor 22 may include a protrusion into which an enclosure 24 may be inserted/attached. In some aspects, the enclosure 24 may be circular in shape, as depicted in FIGS. 1 and 2. A bearing wheel 28 may be attached to the enclosure 24 via an enclosure bearing 26. The distance therebetween may define a circular movement diameter. An up arm 30 may be attached to a proximal end of the bearing wheel 28. In the exemplary aspect depicted in FIGS. 1 and 2, the up arm 30 is shaped as an elongated cuboid.

(14) In some aspects, a top portion of the up arm 30 may be attached to a proximal portion of a holding arm 32. The proximal portion of the holding arm 32 may further include an attachment point 34 to which an object to be moved in a circle may be attached. A distal portion of the holding arm 32 may be attached to the bearing yokes 16 (or the yoke 14) via cross bars 36, as shown in FIGS. 1-4. In some aspects, the cross bars 36 may be shaped as elongated cuboids.

(15) The system may act as a reversed gyroscope. An upright object may be attached to the attachment point 34, which may be firmly attached to the holding arm 32. The holding arm 32 may act as a spinning axis (which may not spin). The holding arm 32 may just be an arm driven by the motor 22. Specifically, when the motor 22 is switched ON, the motor 22 rotates the bearing wheel 28, which causes the up arm 30 and the holding arm 32 to move in a circular motion, while the up arm 30 stays in the upright position. Since the up arm 30 stays in the upright position, the object attached to the attachment point 34 also stays in the upright position when the object moves in the circular motion.

(16) In some aspects, an offset may exist between the centers of the rotating holding arm 32 (specifically the spinning axis or the longitudinal axis of the holding arm 32) and the motor axis. In some aspects, the offset may be the distance between the holding arm 32 (when the holding arm 32 may not be moving) and the motor axis (or the motor 22). The offset between the centers of the holding arm 32 (i.e., the spinning axis) and the motor axis together with the length of the holding arm 32/spinning axis defines the radius of the circular movement of the object. A person ordinarily skilled in the art may appreciate that like in gyroscope, all the three axes (spinning axis, horizontal axis and vertical axis) of the system must cross at a common center.

(17) To make the system, an operator may first identify the required/desired radius of circular movement of the object. The operator may further identify a weight of an object (or weights of objects) to be moved in a circular motion. The operator may then accordingly identify a proper enclosure bearing 26 and bearing wheel 28. The operator may further calculate an optimal offset/distance between the spinning axis (i.e., the holding arm 32) and the motor axis, and calculate the length of the holding arm 32, to enable efficient circular movement of the object.

(18) To operate the system, the operator may turn ON the system/motor 22. The system may further include a dial potentiometer, using which the operator may increase or decrease the speed of the circular movement of the object. The system may further include a stepper motor controller that may control the speed, direction and exact position of the object when the object moves in the circular motion. The system may additionally include a game controller that may enable the operator to remotely control the stepper motor.

(19) The system, as disclosed in the present disclosure, may be used in a plurality of application areas or products. For example, the system may be used in a Ferris wheel, robotic eyes, power vibrator for a sex toy or a kitchen appliance, a pilot training cabin, a highest precision self-guided anti-aircraft gun using a stepper motor, and/or the like.

(20) In some aspects, the bearings disclosed in the present disclosure may be self-aligning ball bearings.

(21) Except as may be expressly otherwise indicated, the article a or an if and as used herein is not intended to limit, and should not be construed as limiting, the description or a claim to a single element to which the article refers. Rather, the article a or an if and as used herein is intended to cover one or more such elements, unless the text expressly indicates otherwise.

(22) This invention is susceptible to considerable variation within the spirit and scope of the appended claims.
