Abstract: One embodiment of an occupant propelled roundabout (“roundabout”) may have a body. The roundabout may also have a carrier, which may be rotatably carried by the body and may also have a seat assembly adapted to carry an occupant. In addition, the roundabout may also have a drive mechanism pivotally coupled to the seat assembly such that the drive mechanism may be movable between a deployed position and a retracted position. The drive mechanism may be moved toward the deployed position in response to the occupant operating the drive mechanism. Also, the roundabout may have a biasing member, which may be operably connected between the drive mechanism and the carrier so that the biasing member may move the drive mechanism toward the retracted position.

Abstract: A pedaling exerciser with a twister device has a base, a twister device mounted on the base, a pedaling assembly combined with the twister device, and an optional shell covering crank drums of the pedaling assembly. The twister device is composed of an intermediate plate and a rotating plate mounted. The intermediate plate is secured on a central shaft of the base and has multiple balls rotatably mounted thereon. The rotating plate rotatably mounted on the intermediate plate and has a bearing attached thereon around the central shaft to keep the rotating plate stable during rotation. Moreover, the rotating plate has a pin assembly movably engaged the intermediate plate to lock the twister device. By having the twister device, the pedaling exerciser selectively works pedaling and twisting functions at the same time.

Abstract: A first embodiment of carousel device provides a bouncer which cannot be tipped over accidentally. Further, a oscillating circuit enables a battery-operated motor to gently oscillate the bouncer through an 80° arc. A pair of retractable rockers are provided on the bottom of the stationary base to afford the baby additional motion while bouncing. A second embodiment provides a straddlable vehicle which a youngster can peddle, a sound circuit being activated by the pedaling as inducement to continue exercising.

Abstract: An amusement swing apparatus for children and adults alike and more particularly, a horizontal rotating manually operated swing. It can be conceptualized as two seesaws lapped in the middle at right angles, but instead of the riders going up and down, they remain in a horizontal plane and rotates about the centre point. Where these beams cross at the middle, they are supported on a housing that carries two bearings, one on top of the housing and one at the bottom. This housing is fitted to a vertical shaft that passes through the centre of the lapped beams and allows the housing with the lapped beams to rotate freely around it. The shaft is firmly fixed to the ground or floor surface. Four or six legs, attached to a flange welded to the shaft add support to the structure. These legs spread out evenly around the flange and are fixed to the ground or floor surface. The four outer ends of the beams have seats for persons to sit on.

Abstract: A firearm laser training system according to the present invention includes a laser transmitter assembly and a cartridge adapter assembly, while employing modified blank cartridges to simulate firearm operation. The modified blank cartridges each have a quantity of explosive substance sufficient only to cycle the firearm. The laser assembly is configured for attachment to a firearm barrel and front sight and emits a beam of laser light toward a training system target in response to actuation of the firearm trigger. The laser beam is generally in the form of a pulse having a duration sufficient for the system target to detect a beam impact location. The cartridge assembly is disposed within the firearm barrel to adapt the firearm for compatibility with the modified blank cartridges for simulating firearm operation.

Abstract: Leisure equipment is disclosed which permits an experience of fully controlled loop-the-loop rotary motion with a wheeled vehicle. The leisure equipment comprises a frame structure with a trough-shaped wheel track, an axis of rotation and at least one rotating arm with one wheeled vehicle each. The trough-shaped wheel track is curved so as to form a closed contour. The axis of rotation is contained within this contour. At least one rotating arm is rotatably supported on this axis of rotation. At the rotating arm a wheeled vehicle is fastened which is adapted to be guided in the wheel track. The wheeled vehicle is pressed into the wheel track by a pressing device acting on the rotating arm. In this way a contact of wheel track and wheeled vehicle exists in every point of the wheel track. With the wheeled vehicle of the leisure equipment, a rider can perform loop-the-loop rotary motions or revolutions during which he retains full command of the motion at all times.

Abstract: A rotary and rocking toy device has four bottom seats, four roller wheels, four support frames, and four carriers. The support frames are connected together to form a cross shape. Each roller wheel is disposed on the respective bottom seat. Each support frame is connected to the respective roller wheel pivotally. Each carrier is connected to the respective support frame stably.

Abstract: A human powered centrifuge has independently established turntable angular velocity and human power input. A control system allows excess input power to be stored as electric energy in a battery or dissipated as heat through a resistor. In a mechanical embodiment, the excess power is dissipated in a friction brake.

Abstract: A user propelled merry-go-round including a base with a post centrally coupled to a top surface thereof and extending upwards therefrom. Also included is a support pivotally coupled to the post. The support has a plurality of support members extending radially from the post. A plurality of wheel forks are each coupled to an associated support member and extended vertically downward therefrom with an axially aligned bore formed therein. A plurality of bicycle frames are each coupled to an associated support member with a seat situated thereon. Wheels with associated sprockets are each axially coupled to one of the forks via the bore thereof. A plurality of pedal units are axially coupled to an associated bicycle frame whereby the sprocket of the pedal unit and the sprocket of the wheel reside in a similar plane with a chain operatively coupled therebetween for allowing a user to precess about the post upon the rotation of the pedal unit.

A frame rotates about a stationary shaft located above the head of the rider. Power is provided by the rider via pedals and handles in a bicycle type apparatus. A plurality of gears may be selected using a derailleur and freewheel. A brake may be used to increase resistance and thus workout intensity. A cam and roller device at the foot crankset simulates impact loading of normal earth walking.

Abstract: A roundabout adapted for play or exercise in the yard using one or a plurality of bicycles secured by top and bottom mounting assemblies to a mounting post rotatable about a fixed post solidly implanted in the ground. The bike or bikes are fastened to mounting assemblies by straps and can be readily disassembled by simply unbuckling the straps. The ground post can be removed and the same placed in another area of the yard. Motive power is supplied by a small wheel placed exteriorly of the front bike wheel and fastened on the bottom mounting assembly.

Abstract: A portable rider-propelled roundabout includes a platform having a circular track formed by a pair of semi-circular halves, a plurality of pedal-propelled riding cycles, and a revolving mechanism operable for supporting the riding cycles upright on the circular track for undergoing revolving movement therealong about a center point defined by the circular track.
