Fig. 9 ~ Figure 13 is the operation chart of slide rail assembly.
First, as shown in Fig. 9 A ~ Fig. 9 D, when this operator with this operating parts 30 pull handle portion 37 by the 3rd rail 26 from this second rail 24 toward one opening direction D1 pull out displacement time, the hook part 148 of the 3rd rail 26 hook accordingly support this actuated piece 100 contact site 110 (as Fig. 9 A, Fig. 9 B), this second rail 24 is driven displacement by the 3rd rail 26, until this second rail 24 this first rail 22 relative is drawn out when being moved to a precalculated position, the contact site 110 of this actuated piece 100 can be guided accordingly by the guidance part 78 of this first rail 22 and depart from from the hook part 148 of the 3rd rail 26 (as Fig. 9 C, Fig. 9 D).Specifically, when the contact site 110 of this actuated piece 100 guided by the horizontal segment 80 of the guidance part 78 of this first rail 22 and be moved to rise section 82 time, this actuated piece 100 pushes the contact-segment 102 of this fixture 98 with afterbody 112 and deflects an angle, preferably, the afterbody 112 of this actuated piece 100 and the contact-segment 102 of this fixture 98 are one of at least flexible materials, the contact site 110 of this actuated piece 100 is made to be easy to depart from (as Fig. 9 C) from the hook part 148 of the 3rd rail 26, the contact site 110 of this actuated piece 100 continues guided by the rise section 82 of this guidance part 78 and be moved to the barricade 84 (as Fig. 9 D) of this guidance part 78 subsequently, this contact site 110 is stopped by the barricade 84 of this guidance part 78.And as shown in Fig. 9 B and Fig. 9 C, the elastic force that the resilient guide portion 96 with this auxiliary member 88 produces, makes the foot 92 of this swing component 86 be guided and enters accordingly and be butted on the recess 114 of this second rail 24.That is, the recess 114 of this second rail 24 can accordingly for this swing component 86 foot 92 against.In this case, this second rail 24 this first rail 22 relative is located.
As shown in fig. 9d, when the contact site 110 of this actuated piece 100 stop by the barricade 84 of the guidance part 78 of this first rail 22, and when the foot 92 of swing component 86 enters the recess 114 of this second rail 24, this second rail 24 is no longer along with the 3rd rail 26 synchronous shift.Now, the 3rd rail 26 can continue toward this opening direction D1 displacement again.
As shown in Figure 10 ~ Figure 13, continue toward in the process of this opening direction D1 displacement at the 3rd rail 26, elastic portion 146 due to this clamping piece 140 has the ability of elastic bending, therefore, when not yet displacement arrives to a position the 3rd rail 26, this elastic portion 146 is pressed the state (as Figure 10 and Figure 12) in an elastic force pressure accumulation between this second rail 24 and the 3rd rail 26; Until when the 3rd rail 26 continues to be moved to this position, namely this elastic portion 146 discharges this elastic force, makes the location division 142 of this clamping piece 140 can enter the opening 152 of the first longitudinal part 32 of the 3rd rail 26 and a corresponding and opening wall 153 that is that can fasten at this opening 152.Now, the 3rd rail 26 is positioned at an enable possition (as Figure 11 and Figure 13).
As shown in Figure 14 ~ Figure 16, when the 3rd rail 26 be positioned at this enable possition and this operator for the 3rd rail 26 is disassembled from this second rail 24 time, this operator only need apply the elastic portion 146 of a strength F1 (as Figure 16) to this clamping piece 140 from the opening 152 of the 3rd rail 26, the location division 142 of this elastic portion 146 is made to leave this opening 152 and no longer to should perforated wall face 153, in this case, operator can extract the 3rd rail 26 out (as Figure 15) toward a disassembly direction D2, to be disassembled from this second rail 24 by the 3rd rail 26.
As shown in Figure 17 A ~ Figure 17 D, after the 3rd rail 26 is removed, this second rail 24 can disassemble from this first rail 22 by this operator further.Wherein, this operator can apply the operating portion 128 that a strength F2 (as Figure 17 B) pulls release member 120, makes the movable part 122 of this release member 120 can this locating part 118 displacement relatively with cannelure 126.Accordingly, with the releasing section 124 of this release member 120 by interlock, make this solution edge 136 of pulling can drive a part for this swing component 86 accordingly (such as, extend sidepiece 94) (now, this flexible body 130 is case of bending by the active force of this block 138), make the foot 92 of this swing component 86 be driven displacement and depart from the recess 114 of this second rail 24 once again.In this case, this second rail 24 can be extracted out toward a disassembly direction D3 by this operator, to be disassembled (as Figure 17 C) from this first rail 22 by this second rail 24.And after operator stops applying strength F2 to pull operating portion 128, this flexible body 130 drives release member 120 to revert to original state (as Figure 17 D) once again.
From Figure 14 ~ Figure 17, the 3rd rail 26 of this slide rail assembly and the second rail 24 can be removed, so so that operator changes cabinet (e.g., machine box for server) or carries out the operation such as replacing, maintenance of slide rail assembly.
As shown in Figure 18 A ~ Figure 18 C, when operator for by this slide rail assembly from above-mentioned this enable possition (state as Figure 11) toward one fold direction D4 displacement and fold time, operator similarly can press the elastic portion 146 (state as Figure 16) of clamping piece 140, and pass the 3rd rail 26 and fold direction D4 displacement toward this, so push away this second rail 24 with the oblique portion 36 Qu Arrived with the 3rd rail 26, the 3rd rail 26 can be folded by this first rail 22 relative with this second rail 24.And when this second rail 24 is moved to a position, the guide ramp 150 of the hook part 148 of the 3rd rail 26 can the contact site 110 of this actuated piece 100 of ejection accordingly, makes the contact site 110 of this actuated piece 100 be propped up by this guide ramp 150 and leave the barricade 84 (as Figure 18 B) of the guidance part 78 of the first rail 22; And the foot 92 of inclined-plane 116 this swing component 86 of Hui Tui Arrived of this second rail 24, make this foot 92 offset and leave this recess 114 (as Figure 18 C).Accordingly, the contact site 110 of this actuated piece 100 can once again by the hook part 148 of the 3rd rail 26 hook to, make the 3rd rail 26, this second rail 24 with this first rail 22 in the state folded (this part can consult Fig. 9 A) simultaneously.
According to above explanation, namely known enhancement effect of the present invention and advantage are:
When the 3rd rail is unlocked toward opening direction, the 3rd rail can synchronously drive this second rail toward this opening direction synchronous shift; And when being moved to a position, this second rail can temporal persistence in this position no longer with the 3rd rail synchronous shift.
Although the present invention describes with reference to current specific embodiment, but those of ordinary skill in the art will be appreciated that, above embodiment is only used to the present invention is described, change and the amendment of various equivalence also can be made when not departing from spirit of the present invention, therefore, as long as all will drop in the scope of the application's claims the change of above-described embodiment, modification in spirit of the present invention.
