The specific embodiment
Below in conjunction with the drawings and specific embodiments multi-point positioning stay for top suspension window of the present invention is described further.
With reference to illustrated in figures 1 and 2, multi-point positioning stay for top suspension window of the present invention is by slide rail 1, sliding support arm 2, spacer 3, spring leaf 4, and ask cantilever 6, holder cantilever 7 to assemble: an end of sliding support arm 2 dashes the breach 10 that the buckle type is arranged, the opening of breach 10 is positioned at the side of sliding support arm 2, and makes at sliding support arm 2 ends formation crotch 21.Spacer 3 is contained in this breach 10, and can in breach 10, move, by Fig. 2 and shown in Figure 3, spacer 3 middle inside relevant positions also have hook 32, there is flange 31 in the spacer outside, flange 31 on the spacer 3 is a hypotenuse towards an end of sliding-rail groove opening, another side is a straight flange, form different stress surfaces respectively, spring leaf 4 is inserted between the straight-arm of spacer 3 and sliding support crook of the arm hook 21, spacer 3, spring leaf 4 is assemblied in the slide rail 1 of packing into behind the relevant position of breach 10 of sliding support arm 2 hooks.Slide rail 1 is the cartridge type slide rail of square-section, the relevant position of the corresponding spacer flange 31 of slide rail 1 one sides dashes several breach 9, and spacer 3 protrudes from the breach 10 of sliding support arm usually and puts in some breach 9 on the slide rail under the elastic force effect of spring leaf 4.
If the port of slide rail 1 openend reduces, in the time of can guaranteeing that window is opened to maximum, sliding support arm 2 can not deviate from slide rail 1.As shown in Figure 2, the technical scheme that the present invention then adopts is: slide rail 1 has an end of opening at it, being positioned at one side of jagged 9 bends inwards and narrows down at its open end, to reduce its port, make like this when the sliding support arm is pulled outwardly, move this position to because port narrows down, slide rail 1 can slidably reciprocate but it then can not pass through with a end that spacer 3 assembles sliding support arm 2 by this port, prevents that the sliding support arm from deviating from slide rail 1.Flange 31 by the 10 inside compression set bit slices 3 of the breach on the slide rail 1 inwardly contracts it, and contract by distance guarantees that the hook 31 of spacer does not hang over the crotch 21 of sliding support arm, can make sliding support arm 2 slide in slide rail 1.As shown in Figure 4, in the present invention, the changeover portion of slide rail convergent forms the spacing summit 8 that extruding spacer 3 makes its contraction, this summit 8 can crowded spacer flange when contacting with spacer 3 hypotenuse it is shunk in breach 10, and spacer 3 slightly moves to the crotch direction, hang over to its hook 32 crotches 21 on sliding support arm 2, form locking, this moment, the flange 31 of spacer can not stretch in the breach of slide rail 1.
Slide rail also comprises a stator 5, and stator 5 is contained in the big end of slide rail port and fixing, stretches out in the relevant position riveted joint holder cantilever 6 and the holder cantilever 7 of an end of slide rail and the end that stator 5 stretches out in slide rail at sliding support arm 2.
For can automatic unlocking, as shown in Figures 2 and 3, the flange 33 that oriented stator direction protrudes out on the spacer 3.With reference to shown in Figure 2, when sliding support arm 2 inserted the slide rail bottom, the flange 33 of spacer acted on stator 5, stopped by it spacer is moved to breach 10 another sides, and displacement can make crotch 21 unhook of hook 32 with the sliding support arm of spacer 3.This moment, stator 5 used as a unhook piece, bearing pin can certainly be installed on slide block or inside punching press forms projection, to act on stator as the unhook piece.
Breach 10 on the sliding support arm 2 is circular-arc at the end away from its crotch 21, in this end outside rib 22 is arranged, and the 3 pairs of ends that should hold of spacer are similarly circular-arc.This rib 22 cooperates with crotch 21, can make spacer 3 be difficult for deviating from when the sliding support arm slides, and is that rotate in the center of circle with this end under spring leaf 4 effect.
The action principle of this sliding support is such: one-to-many point location spacer is installed on the top, (holder cantilever 6 is installed on the window frame, holder cantilever 7 is installed on the sash), remove the power of windowing after sash opened to arbitrary fixed position (spacer 3 puts in some breach), then the deadweight of sash makes sliding support arm 2 toward the shrinkage direction motion, because this moment, spacer 3 was a vertical plane with the stress surface that contacts of the breach 10 of slide rail 1, no transverse component makes spacer 3 compression spring leafs 4, spacer 3 can not be retracted in slide rail interior 1, sliding support arm 2 can not continue to be positioned this position thereby sash can not continue to close toward the shrinkage direction motion; In the time will closing sash, earlier sash is moved toward opening direction, sash moves toward direction of extension by the holder cantilever 7 band sliding support arms 2 that are installed on sash, slide rail 1 breach 9 one ends make spacer 3 compression spring leafs 4 by the power that acts on spacer 3 flange hypotenuses and are retracted in the slide rail 1, sliding support arm 2 can be continued toward the direction of extension motion, when spacer 3 moves to slide rail 1 and bends inwards the position on one side with sliding support arm 2, because port is little, one end of sliding support arm 2 assembling and positioning sheets 3 and spring leaf 4 can not pass through, prevent that the sliding support arm from deviating from slide rail, and spacer 3 limited summits 8 compressions and being pushed in the breach of hook of sliding support arm 2, the hook 32 of spacer 3 and the crotch 21 of sliding support arm 2 are buckled together, and this moment, the elastic force of spring leaf 4 can not make spacer 3 put in some breach and stop closing of sash.When sash is closed fully, stator 5 ends by the flange 33 on the spacer 3 with spacer 3 to top, breach end and push up go back to original position, the hook 32 of spacer 3 and the crotch 21 of sliding support arm 2 no longer are buckled together, recovered positioning function again.
This top is not only simple in structure, easy to operate with the multipoint positioning spacer, and can realize multipoint positioning, and is safe and reliable, is a kind of desirable spacer.
