Playground device, for example a swing or a see saw, having a ground supported, movable part and at least one motion sensor configured for sensing the motion of the movable part. The motion sensor is functionally connected to a sound signal feedback generator that is configured for converting the signals from the motion sensor into a sound feedback in response to the motion of the movable part. The sensors are mechanically connected only to the movable part in order to provide system with a large number of variations of embodiments.

An adjustable center of gravity type balancing teeterboard is characterized in that a counter weight is arranged on a bottom plate of the teeterboard, screws penetrate the counter weight and penetrate through screw holes formed in the bottom plate of the teeterboard, and two ends of each screw are respectively fixed with a steering disk. Two fixing strips are respectively welded on two sides of a protective cover. The lower ends of the fixing strips are fixed on the bottom plate of the teeterboard through screws. A scale is engraved on the protective cover. Two ends of the bottom plate of the teeterboard are provided with seats. A supporting point shifter is welded on the bottom plate of the teeterboard. The screw A passes through the supporting point shifter. When the adjustable center of gravity type balancing teeterboard is used, the counter weight moves horizontally to adjust the center of gravity, and the supporting point shifter is adjusted to one side which is light in weight, so that people who are great in difference of weights can also play with the teeterboard. The counter weight is moved to one side without people sitting, so that one person can play with the teeterboard. If the counter weight is not enough, the supporting point shifter is adjusted to move the bottom plate of the teeterboard to the direction without people. When the teeterboard is played, two hands can practice rotating the steering disks, and therefore flexibility of the hands is practiced. When the teeterboard is tilted vertically, the steering disk held by the hands can adjust balancing of a body.

The invention discloses a cockhorse seesaw which comprises an arc-shaped base, wherein a middle seat board is arranged on the arc-shaped base, balance bars are respectively arranged at two ends of the middle seat board, second seat boards and third seat boards are respectively arranged on the balance bars at the two ends of the middle seat board, limit stabilizing legs are arranged at two sides of an arc surface of the arc-shaped base, and at least two parallel balance bars are arranged at each end of the middle seat board. According to the invention, the arc-shaped base and the balance bars of a cockhorse are combined together ingeniously, and multiple functions of the cockhorse and the seesaw are realized by adopting the structures of the middle seat board and the seat boards at the two ends; and the cockhorse seesaw has the advantages of reasonable and simple structure, reduced occupation space and convenience for storage, is movable, and can be used indoors and outdoors.

In an image forming apparatus using an engine part which is capable of moving in the width direction of paper fed in the print direction, a printing method has the steps of measuring a position in the width direction of paper fed in the print position, comparing measured position value with a preset reference position value, compensating a position to be printed based on the compared difference, and printing on the paper based on the compensated position data.

The invention discloses a four-position teeterboard which comprises an upright post (1) and teeterboards (2) and is characterized in that the teeterboards (2) are respectively arranged at two sides of the upright post (1). The invention can be used by a plurality of persons simultaneously.

The invention relates to a rotating seesaw. The rotating seesaw comprises a base and a balancing plate which is rotatably connected with the base, seats are arranged at two ends of the balancing plate, armrests are arranged at front ends of the seats, the base comprises a round base plate and two arc-shaped supporting plates, the arc-shaped supporting plates are rotatably connected with the base plate and arranged on two sides of the balancing plate, the balancing plate is rotatably connected with the arc-shaped supporting plates, and a rotating shaft is arranged between the balancing plate and the base plate. During the up-and-down movement of the seesaw, a force in the horizontal direction is applied to the seesaw simultaneously, so that the seesaw can move up and down while rotating horizontally; and meanwhile, the seesaw has a bodybuilding function.

The invention relates to a flower watering device, in particular to a seesaw-type interactive flower watering device. The technical problem to be solved by the invention is to provide an recreationaldouble-seesaw interactive flower watering device. The seesaw-type interactive flower watering device is provided and includes a base, a first support frame, a second support frame, a third support frame, a connection rod, a fixing block, a fourth support frame, a first support rod, a second support rod, seats, a wedge block and the like. The left side of the upper portion of the base is fixedly connected with the first support frame, the right side of the upper portion of the base is fixedly connected with the second support frame, the upper portions of the first support frame and the second support frame are fixedly connected with the third support frame, and the middle of the lower portion of the third support frame is fixedly connected with the connection rod. When people play a seesaw,flowers can be waters, the problems that children feel boring after playing the seesaw for a long period of time and have no sense of achievement, the flower watering mode is monotonous and much timeand labor are consumed are solved, and the device has the advantages of being convenient and safe to use, easy to operate, low in manufacturing cost and the like.
