Mattress (omitting among the figure) is placed on the bedstead, and adopts the nylon adhesive tape tension.
Again the power-assisted rising and falling bed process of rising and falling of the utility model air spring is described specifically below:
Air spring is power-assisted rising and falling bed to have three states: level is that normal operating condition (referring to Fig. 1 and Fig. 2), plumbness are that collapsed state (referring to Fig. 4), the state of rising and falling are the motion process (referring to Fig. 5) of the mutual conversion of above-mentioned two states, also is that the bedstead that comprises mattress turns over the compound motion that turn 90 degrees with translation.
Referring to Fig. 1 and Fig. 2, introduce this level: bedstead 1 is parallel to ground, by two fixedly footpost 8 and two movable footpost 9 together support, keeps stable state.Following three air springs 14 of this state all are in the original position of impulse stroke, piston rod all is compressed to extreme position, because the angle during this state between Rocker arm 5 and air spring 14 axis big (about 170 degree), the component that makes progress in the thrust of three air springs 14 is less than the gravity of bed, so bed accessory keeps stable level.
Referring to Fig. 4, introduce this plumbness: bedstead 1 is perpendicular to ground, and 2 roller 4 together support by 4 rollers and the tailstock plate rear side of two movable footposts 9 keep stable status.The impulse stroke of following three air springs 14 of this state finishes, and piston rod reaches free position fully, and air spring thrust is zero.Therefore bed accessory also keeps stable plumbness.
Referring to Fig. 5, introduce this process that erects: by a little firmly upwards praise bedstead 1 (omitting mattress) near a side of bed screen 3 for expressing among the clear figure, bedstead 1 is near bed screen one side (promptly bed is anterior), under air spring 14 effects, slowly erect, bedstead 1 serves as axle turn clockwise (being observed by bed left side) with movable footpost jointed shaft 10, movable footpost 9 shields 3 close gradually to bed, bedstead 1 forwards to when approximately becoming 30 to spend with ground, middle air spring 14 impulse strokes finish, bedstead 1 forwards to when approximately becoming 80 to spend with ground, air spring 14 impulse strokes on both sides finish, need shield 3 directions to bed in the position at tailstock plate 2 middle parts and touch bedstead 1 this moment, and bedstead 1 can continue rotation till vertical and ground.Erect operation and abbreviate " one lifts one pushes away " as.
Erect air spring mechanism in the process at bed: in the incipient stage that bedstead 1 erects, three air springs 14 all are in the original position of its impulse stroke, piston rod all begins to discharge from the extreme position of compression, the common bedstead that promotes erects, at this moment, total lifting force is three air spring lifting force sums.But, the impulse stroke difference of three air springs, the piston rod of a middle air spring is shorter, its impulse stroke is also shorter: when bedstead 1 erects when about 30 spend, the energy of the piston rod of a middle air spring discharges fully, its impulse stroke finishes, at this moment, total lifting force be about two air spring lifting force sums.Along with bedstead continues to erect, middle air spring piston rod will be by jointed shaft 17 tractives on bedstead 1 crossbeam 12, extract middle air spring cylinder barrel out a part (referring to Fig. 5) from the through hole of big slide block 13 along with the continuing to clockwise rotate of bedstead 1, sleeve spiral cover 16 inboards are left in promptly middle air spring cylinder barrel bottom.But the piston rod length of two air springs on its both sides is all long, and both are identical, all also are in the impulse stroke.When bedstead erects when spending with horizontal plane about 80, two air spring impulse strokes on both sides finish, and the energy of its piston rod also discharges fully; This moment, bedstead 1 will continue to erect, just must promote bedstead 1 by tailstock portion to the direction of bed screen 3 by manpower, vertical fully up to bedstead 1, at this moment, the piston rod of three air springs 14 is all by bedstead crossbeam jointed shaft 17 tractives, its air spring cylinder barrel all is drawn out of a part (referring to Fig. 4) from the through hole of big slide block 13, sleeve spiral cover 16 inboards are left in the cylinder barrel bottom of all air springs 14.
Operating process when introducing this whereabouts again: tailstock plate 2 one sides are provided with handle (omitting among the figure), need this moment the people to the light broaching machine tailgate 2 of direction that leaves bed screen 3, make the movable footpost 9 in bed rear portion move to the direction of leaving bed screen 3, two air springs on both sides are introduced into impulse stroke, its piston rod begins compression displacement, the anterior side of bed slowly falls under these two air spring effects, 1 of bedstead serves as that axle is rotated counterclockwise (being observed by the bed left side) with jointed shaft 10, when turning to when approximately becoming 30 to spend with ground, for preventing bed freely to fall, when this angle, middle air spring also enters impulse stroke, its piston rod begins compression displacement, increases the power of lifting; When bed continued to fall, three air springs can whole compression displacement arrive spacing place, and need a little firmly push bedstead 1 downwards this moment by the people to the bed front portion, finish the dropping process of bed.Fall operation and abbreviate " one draws a pressure " as.
The mechanism that falls the air spring in the process at bed is: before bedstead 1 falls, three air springs all are in free state, spiral cover 16 bottoms of sleeve 15 are all left in the cylinder barrel bottom of air spring 14, all be in free state, shield 3 the light broaching machine tailgate 2 of direction with manpower to leaving bed this moment, bed is a setting in motion, and under the gravity effect of members such as bedstead, the side direction motion in sleeve 15 earlier of the cylinder barrel of three air springs 14; When bedstead 1 moves to when spending with horizontal plane about 80; Spiral cover 16 bottoms of the cylinder barrel elder generation contact sleeve 15 of two air springs 14 on both sides make these two air springs begin to enter impulse stroke, and piston rod enters compressive state, makes bedstead slowly progressively put down.When bedstead 1 is lowered into when about 30 spend, middle air spring cylinder barrel is the bottom of contact sleeve 15 also, and middle air spring also begins to enter impulse stroke, and its piston rod enters compressive state, lifts power to increase it.After this, along with bedstead 1 continue fall, all air springs 14 all are compressed to extreme position, till bedstead 1 is in level fully.
The utility model has carried out implementing test, the sample bed of trial-production is of a size of 1900mm * 1500mm, through the test of rising and falling repeatedly, this bed accessory has been realized goal of the invention fully, and promptly in the bedstead level was put down mutual transfer process with vertical two states that stand up, required manpower was less, motion process at the uniform velocity, steadily, do not have to impact, noiselessness only needs the less strength of single usefulness just can finish whole operating process that bedstead integral body erects and falls, and bedstead shifts near bed after erecting and shields a side wall; Can make full use of the bedroom area, save home room.Therefore, the utlity model has good popularization and application prospect.
