Below, the action about the rising of the seat portion 1 of this chair is described.
By trampling action bars 5 (tread portion 52), as shown in Figure 2, the active force of resistance elastomer 68 moves piston rod 61 downwards.According to this action, pillar valve 63 rises the oil pressure in the 60b of compression chamber to the 60b of compression chamber pressurization.
When the oil pressure in the 60b of compression chamber was higher than the fluid pressure of pressure regulating box 7 (the 1st passage 80 sides), check-valves 8 made its spheroid 81 (downwards) displacement, opens check-valves 8, and the oil of the 60b inside, compression chamber of oil tank 60 enters the 1st passage 80.At this moment, oil is introduced into pressure regulating box 7, and its part directly is introduced in the cylinder 4 from the 2nd passage 9.But as previously mentioned, the stream section by being set at the 1st passage 80 is greater than the stream section of the 2nd passage 9, and directly is admitted to oil phase ratio in the cylinder 4 from second channel 9, and the oil masses of temporarily being sent in the pressure regulating box 7 want many.The internal diameter of the 2nd passage 9 is preferably 0.5mm～1.5mm, and particularly 1.2mm is better.
In addition, Ci Shi secondary check-valves 67 is in closed condition.
After trampling described action bars 5, to the 1st passage 80 side shiftings, when forcing down in pressure regulating box 7 in pressure in the 60b of compression chamber, check-valves 8 cuts out the oil of 60b inside, compression chamber by check-valves 8.Afterwards, pressure regulating box 7 makes moving part 70 displacements according to the active force of elastic portion 71, dwindles internal capacity, from the 2nd passage 9 oil in the pressure regulating box is sent in the cylinder 4, improves the oil pressure in the cylinder 4, and lifting shaft 3 is risen.
For next time trample and when stopping to trample action bars 5, because the active force of elastomer 68, piston rod 61 rises.Rising pillar valve 63 risings along with piston rod 61 thus, produce negative pressure in the 60b of compression chamber, secondary check-valves 67 is opened, and apotheca 60a supplies with oil to the 60b of compression chamber.
By the negative pressure that produces in the cylinder 4 by the rising of described lifting shaft 3, when the oil pressure in the pressure regulating box 7 are lower than oil pressure in the described 60b of compression chamber, be the oil pressure of the 60b of compression chamber when being higher than the oil pressure of pressure regulating box 7 (the 1st passage 80 sides), check-valves 8 makes spheroid 81 displacements, valve-off.
As shown in Figure 1,, lifting shaft 3 is risen, a portion 1 is moved towards the top by so repeatedly trample action.
On the other hand, when reducing seat portion 1, than the above-mentioned more degree of depth the action bars 5 of entering into, make 63 declines of pillar valve, utilize projection 66 that the spheroid 81 of check-valves 8 is depressed.Like this, make spheroid 80 displacements of check-valves 8, forcibly make check-valves 8 be in the valve open state, the oil in the cylinder 4 is flow backwards in hydraulic chamber 60 from the 2nd passage 9.Thus, oil flows out from cylinder 4, and lifting shaft 3 is reduced, and a portion 1 is reduced.During described trampling, by the inner passage 63a in the pillar valve 63, the oil in the 60b of compression chamber flows into apotheca 60a.
The stable state (tranquility) that moves with fluid (oil) in above-mentioned is that benchmark has illustrated, press the on off state of the secondary check-valves 67 that the magnitude relationship of (oil pressure) carries out according to fluid between apotheca 60a and the 60b of compression chamber, the magnitude relationship of fluid pressure (oil pressure) between also with good grounds 60b of compression chamber and the pressure regulating box 7 and the on off state of the check-valves 8 that carries out.But, press change just soon at the fluid of each several part, in short time, fluid between apotheca 60a and the 60b of compression chamber is pressed the magnitude relationship of (oil pressure) and the on off state of secondary check-valves 67, also have fluid between 60b of compression chamber and the pressure regulating box 7 to press the relation of the on off state of the magnitude relationship of (oil pressure) and check-valves 8, can consider and to produce and the inconsistent state of the above state, but in the present patent application, this state is allowed to.Just, after changing of fluid Hair Fixer, under the state that fluid mobile stablized, just passable as long as the relation between the described each several part is set up.
In addition, in said embodiment, when the interior pressure (oil pressure) of apotheca 60a was higher than the interior pressure (oil pressure) of the 60b of compression chamber, secondary check-valves 67 made the spheroid displacement and cuts out.In addition, for example can implement such operation: on interior pressure (oil pressure), add the bounce (active force) of the spring of spheroid 67a active force at the 60b of compression chamber and power, when being higher than the interior pressure (oil pressure) of apotheca 60a, secondary check-valves 67 cuts out, on interior pressure (oil pressure), add the bounce (active force) of the spring of spheroid 67a active force at the 60b of compression chamber and power, when being lower than the interior pressure (oil pressure) of apotheca 60a, secondary check-valves 67 is opened.
Equally, in said embodiment, when the interior pressure of pressure regulating box 7 (the 1st passage 80 sides) was higher than the interior pressure of the 60b of compression chamber, check-valves 8 made spheroid 81 displacements and opens.This occasion, also can implement such operation: when the power that gets was higher than the interior pressure of the 60b of compression chamber when press the bounce (active force) that adds the spring that acts on above-mentioned spheroid 81 in pressure regulating box 7 (the 1st passage 80 sides), check-valves 8 made spheroid 81 displacements and cuts out; When the power that gets was lower than the interior pressure of the 60b of compression chamber when press the bounce (active force) that adds the spring that acts on above-mentioned spheroid 81 in pressure regulating box 7 (the 1st passage 80 sides), check-valves 8 made spheroid 81 displacements and opens.That is to say that the benchmark of the switch of secondary check-valves 67 and check-valves 8 is not limited to above-mentioned
Embodiment.
In the above-described embodiment, fluid is an oil, and pump 6 is an oil pressure pump.But also can not use oil, and other fluid that gases such as use air maybe can pressurize, employing can be implemented the pump that these fluids pressurize.
