Description

Seesaw rides {The seesaw type of appliance}

The present invention relates to a seesaw playground equipment, and more particularly, to a seesaw playground equipment that improves the motility and safety of the seesaw by maintaining the balance of the seesaw horizontal during the seesaw movement.

In general, seesaws are essentially installed along with swings and slides for children in amusement facilities such as schools, parks, and playgrounds. The seesaw is a play equipment that uses balance of power and is a basic play equipment and learning tool for developing children's sense of balance and cooperation.

  The conventional seesaw is rotatably installed by creating a bearing in the middle of the balance bar on a support standing perpendicular to the ground. When children sit or stand at both ends of the balance bar and tilt to one side according to the weight of the body, it is a play equipment that rebounds up and down by the repulsive force of elastic bodies such as waste tires or the foot cloud of the children.

  By the way, the balance bar is composed of one bar shape, so the inclination occurs on the parallel during the seesaw motion. Sloped slopes are limited because children can be threatened and risky. As the slope is limited, the vertical movement of the seesaw is also very limited, and it is difficult to induce children's interest. In order to increase the vertical movement, the balance bar should be long, but there is a problem of facility space.

  In addition, the seesaw is a play equipment using a balance of power, and must ride at the balance point according to the weight of the child riding the seesaw. The conventional seesaw has a structure in which a riding position is fixed and it is difficult to ride at a balance point.

  In addition, in order to generate a repulsive force during the seesaw exercise, the center of gravity of the child above must be moved backward from the center of the seesaw, and the center of gravity of the child below must be moved forward to generate the repulsive force according to the principle of force balance. However, in the structure of the conventional seesaw, the center of gravity of the child above is tilted forward and the center of gravity of the child below is tilted backward due to the tilting of the seesaw, which is not suitable for the principle of balance of force and is more suitable for the seesaw to rebound. There is a problem that requires a large repulsive force.

An object of the present invention is to provide a seesaw-type playground equipment that can maintain the balance bar and the ground level even during the seesaw movement to improve the mobility as a play equipment, promote safety and further reduce the installation space.

The seesaw-type playground equipment of the present invention is equipped with a pair of balance bars 10 each having a bench portion 11 on one side surface, and are mounted on the left and right sides of the pair of balance bars 10 respectively, and both ends thereof are the two. A pair of connecting members 20 attached to each other so as to be rotatably supported with respect to the side of the balance bar 10, and each of the connecting members 20 mounted on an outer surface of the pair of connecting members, each upper side corresponding thereto. The support member 30 is mounted on the ground and a pair of support members 30 are attached to the ground in the center between the two centers of rotation formed on both ends of the support and the lower end of the support 30 is fixed to each other, the support member 31 Consisting of a predetermined distance between the line formed by the two rotation centers formed by the balance bar 10 and the two connection member 20, the balance bar 10 and the connection member 20 The rotation so as to be parallel to each other) Sims are formed, characterized in that when the balance bar (10) of the pair be in a straight line is arranged so that the predetermined spacing between the balance bar.

Seesaw-type playground equipment according to the present invention, so that even during the seesaw exercise, the balance bar 10 is level with the ground so that the child riding on the seesaw does not tilt and can ride the seesaw in a comfortable and free state. It also rides in arbitrary positions to provide a balance point. While providing higher vertical movement, the installation space can be reduced. It can also be configured for indoor use, and especially for small children, it can be used for various purposes such as seesaws, shakers, and table chairs.

Hereinafter, preferred embodiments of the seesaw-type playground equipment according to the present invention will be described in detail with reference to the accompanying drawings, and in describing the present invention, related well-known technologies and the like will be described in detail when it is possible to obscure the subject matter of the present invention. Will be omitted.

  1 to 3 are a perspective view and a side view of the seesaw playground equipment according to the present invention is a pair of balance bar 10, a pair of connecting member 20 and a pair of support (30) and It is comprised by the support member 31.

  The pair of balance bars 10 is provided in the shape of a bar on the upper surface of the bench 11 for children to ride on the other side is connected to the pair of connecting members 20. Each balance bar 10 rotates in opposite directions to provide a seesaw motion to the child who rides.

  The pair of connecting members 20 are respectively mounted on the left and right sides of the pair of balance bars 10 so that there is no interference between the two connecting members 20 during the seesaw movement. Both ends of each connecting member 20 are attached so as to be rotated with respect to the sides of the two balance bars 10, respectively. The rotation centers are arranged so that the balance bar 10 and the connection member 20 are in parallel with each other at a predetermined distance between the lines formed by the balance bar 10 and the two rotation centers formed by the two connection members 20. Is formed. The squares formed by the centers of rotation become equilibrium quadrilaterals. The distance between the lines formed by the center of rotation is selected in consideration of the load and installation space acting on the bench 11 and the balance bar 10. In case of sit-down seesaw, consider the space where the bench 11 is to be formed and consider the strength of the balance bar 10 and the rotational support according to the load and moment acting when the child rides at the end of the balance bar 10. do. The greater the distance between the centers of rotation, the better the safety, but the less the motility. Therefore, the distance between the centers of rotation should be adapted to the use of the seesaw and its purpose.

  As shown in FIG. 3, there is no interference between the balance bars 10 during the seesaw movement when the pair of balance bars 10 are in a straight line, that is, when the two balance bars intersect. Figure 4 is a top view according to another embodiment of the present invention is an example of increasing the distance between the center of rotation line and the connection member 20 is shortened. As shown in FIG. 4, the portions of the two balance bars 10 that are not attached to the connection member 20 may be bent and spaced apart from each other.

  Each connecting member 20 is supported by a pair of supports 30. The pair of supports 30 are mounted on the outer surface of the connecting member 20, respectively. The upper side surface of each support 30 is attached so that the connection member 20 is rotationally supported at the center between two rotation centers formed at both ends of the corresponding connection member 20. The lower end of the support 30 is erected on the support member 31 is fixed respectively. The supporting member 31 is mounted on the ground and serves to maintain a gap between the two supports 30. In the case of outdoor use, the supporting member may be ground.

As is known, the rotation support is composed of a rotating shaft 21, a rotating hole 22 and the separation prevention cap 23 and the like, and a bearing is used for more smooth rotation. The rotation shaft 21 and the rotation hole 22 may be formed in any form between the rotationally supported balance bar 10 and the connection member 20 and between the connection member 20 and the support 30. The illustrated figure is an example in which the rotating hole 22 is configured in the connecting member 20 and the rotating shaft 21 is formed in the balance bar 10 and the support 30, and conversely, the rotating shaft 21 is configured in the connecting member 20. And the balance bar 10 and the support member 30, the rotation hole 22 in the configuration is also possible.

Bench portion 11 preferably further has a pair of handle bars 12 arranged in the longitudinal direction on the left and right sides of the balance bar (10). Children sit on the bench 11 or ride on the seesaw. Providing the safety handle in the width direction has the disadvantage that the child's riding position is limited. The child can choose the riding position arbitrarily to find the balance of the seesaw. Since the balance bar 10 is horizontal, even if the handle bar 12 is provided in the longitudinal direction, it is not a big problem for safety.

It is preferable to attach the elastic member 40 to the bottom of the pair of balance bars 10. Seesaw rides are important for safety as children's equipment. The elastic member 40 prevents the risk of safety accidents due to sudden operation. The elastic member 40 is an elastic band or plate-shaped member and both ends thereof are fixedly coupled to the bottom of the balance bar 10. Elastic member 40 is bent or stretched by the seesaw movement to mitigate the impact and further provides a repulsive force at the point of maximum movement.

  The operation state of the seesaw playground equipment according to the present invention configured as described above will be described with reference to FIG.

  One child of two children rides on one balance bar 10 and the other child rides on a balance bar 10 that has been lifted off the balance bar 10. Two children move back and forth on the balance bar (10) to find the balance point to hold the handle bar (12) on the left and right. The child at the top of the balance moves back and the child at the bottom moves forward to change the position of the seesaw. If the seesaw changes position, you can ride the seesaw while doing the opposite. This allows children to learn the principle of balance of power.

  When the center of rotation of the center of the connecting member 20 is fixed by the support 30 and both ends are in a circular motion, two points of the balance bar 10 are raised or lowered simultaneously by the two connecting members 20 so that the balance bar ( 10) can be level. Since the balance bar 10 is horizontal, the child's body is not inclined, so it is not dangerous to move the body back and forth, or lean back or down.

In addition, the elastic member 40 is partially contracted or relaxed as the balance bar 10 moves up and down. When the elastic force of the elastic member 40 is maximized or the direction of movement of the balance bar 10 is changed, it acts as a repulsive force. In addition, in the situation where the balance of power collapses, such as falling or falling from the balance bar 10 serves to absorb shock.

  Figure 6 is a side view according to another embodiment of the present invention, a mechanism that combines a swing and a table chair in addition to the seesaw function. It can be used as a device for infants mainly indoors.

  Attach the seat 13 to the bench 11, the length of the support 30 is longer than the balance bar 10 is fully down state and the anti-rotation device 50 for preventing the rotation of the balance bar 10 Have more. The anti-rotation device 50 may be implemented in various forms known in the art, and the anti-rotation member shown in FIG. 5 may include a fixing hole 51 formed in the connecting member 20 and a support base corresponding to the fixing hole 51. It consists of a plurality of corresponding holes 52 formed in the 30, and the fixing pin 55 that can be inserted into the fixing hole 51 and the corresponding hole 52 to prevent rotation and adjust the height.

  Infants are not able to actively exercise the seesaw so that the infant to ride the seat (13) and parents push or push the balance bar 10 with the feet or hands on the other side to allow the infant to enjoy the vertical movement. In addition, shaking the balance bar (10) came down to ride the infant back and forth to use as a shake. In addition, the balance bar 10 is fixed to the anti-rotation member 50 and the seat 13 on the upper side is used as a height adjustable baby dining chair.
