Abstract
The utility model discloses an entertainment seesaw that can make up-and-down and rotating movements. The utility model comprises two arms of the seesaw, a pin shaft, a rotating shaft and a flexible support leg. When a player sitting on a seat forcibly pedals the pedals, the flexible support leg can rotate the seesaw.
Description
The present invention relates to a kind of improved seesaw, particularly a kind of seesaw that can rotate.Can be for people's amusement of all ages and classes.
Existing seesaw mainly is made up of both arms and middle bearing pin.General common seesaw is exactly this form.When amusement, seesaw can only be done motion up and down in a certain vertical plane.Therefore, general seesaw can not rotate, and this often makes the entertainer feel dull, lacks interesting.
Task of the present invention is that a kind of improved seesaw will be provided, and it can either move up and down, and can rotate again.
Task of the present invention is finished as follows:
The both arms mid point of seesaw is fixed on the bearing pin of a horizontal level, allows to rotate around bearing pin.Bearing pin is fixed in the rotating shaft that can do to horizontally rotate, allows to rotate around rotating shaft.The elasticity spike of two band ground blocks is housed in the seat bottom at seesaw two ends.The pedal that pin is put in a confession is housed on this spike, as long as both feet are firmly stepped on pedal pedal, be with the just compression of flexible spike, the spike after the compression must recover, this process has just played the effect that is equivalent to the two the feet step on the ground of general seesaw, and seesaw is moved up and down.Because the active force of both feet is always unequal, so over the ground stressed also unequal of two spikes in seat bottom.After being made for joint efforts of they moved up and down counteracting, remaining component just produced one and horizontally rotates power.
Structure uniqueness of the present invention, interesting strong, can make fixed or portable.When the example structure that will describe in detail below adopting, other number of packages order and cost almost increase seldom.Below with reference to accompanying drawing invention is described in further detail.
Fig. 1 is a kind of structural representation of the present invention.
Fig. 2 is the applied a kind of seat schematic diagram of the present invention.
With reference to Fig. 1, the seesaw both arms (2) that two ends have a seat (1) by pivot on a bearing pin that horizontally rotates (4).Bearing pin (4) by pivot in the rotating shaft that can do to horizontally rotate (3).Rotating shaft (3) stands upright on the strut (5).
With reference to Fig. 2, the metallic support pin (8) of seesaw seat bottom upper end is welded with a slice back-up ring (10), with overcoat (7) that pedal (9) links to each other in also be welded with a slice back-up ring (12), compress spring (11) and be positioned between these two back-up rings (10) (12).The head of metal leg (8) exposes by the centre bore of compression spring (11) and back-up ring (12).In addition, stop bit circle (6) is arranged on the upper surface of overcoat (7), be welded with the ground block (14) of band spike (13) on the lower surface.Above-mentioned textural association is work like this: after certain one arm of seesaw landed downwards, compression spring (11) made spring (11) compression by the back-up ring (12) in ground block (14) and the overcoat (7).Spring after being compressed (11) certainly will will recover.Elastic force just produces a holder power that makes progress by metal leg (8) to seat thus.This moment, as the Pedalling that tramps with one's feet (9), the effect that then has acceleration, reinforcement compression spring (11) restoring force.Because metal leg (8) designs to such an extent that make and the ground out of plumb together with the overcoat (7) of same axial line, so this holder force direction that makes progress is slightly with inclination.From the seat back, two strip metal pin (8) about the seat bottom is positioned at are to be splay, and the angle between them is less than 60 degree.After two holder power that make progress on the two strip metal pin (comprising the active force that two pedals form) are synthetic, both produced a power vertically upward, and produced the power with ground inclination again, the one arm that seesaw was landed is originally lifted up ， And again and is had rotation.Meanwhile, the one arm in addition of seesaw will fall from original higher band of position rotatably because original equilibrium condition is destroyed, continue to repeat the course of action of front after landing again.
Claims (2)
1, seesaw that has seat [1] at both arms [2] two ends is characterized in that its both arms while pivot is on bearing pin [4] and in the rotating shaft [3].
2, by the seesaw of claim 1 regulation, it is characterized in that resiliency supported pin (8) being installed in the bottom of seat (1).
