Abstract
The invention relates to a sliding rail assembly which comprises a first rail, a second rail, a third rail, a guide base, a first contact part and a second contact part. The second rail is in sliding connection with the first rail and is provided with an open hole. The third rail is in sliding connection with the second rail. The guide base is arranged on the first rail. The first contact part is arranged on the second rail, and a part of the first contact part penetrates through the open hole in the second rail and corresponds to the guide base. The second contact part is arranged on the third rail and corresponds to the first contact part. When the third rail is pulled out, the first contact part makes contact with the second contact part, so that the second rail synchronously moves as the third rail is pulled out. The first contact part is guided to another position by means of guidance of the guide base, so that the second contact part disengages from the first contact part, and the third rail can be pulled out relative to the second rail.

Detailed description of the invention
The slide rail assembly that Fig. 1 shows the embodiment of the present invention comprises one first rail 10,1 second rail 12, the 3rd rail 14, holder 16, guide seat 18,1 first contact 20 and one second contact 22.
This first rail 10 comprises wall 24a on, once wall 24b and a side wall 26 extension is connected on this between wall 24a and this lower wall 24b, wall 24a, this lower wall 24b and this side wall 26 definition one first passage 28 jointly on this.Wherein, this side wall 26 has an a front end 30a and end 30b.
This second rail 12 is these first rails 10 that are slidably connected, this second rail 12 also comprises wall 32a on, once wall 32b and a side wall 34 extension is connected on this between wall 32a and this lower wall 32b, wall 32a, this lower wall 32b and this side wall 34 definition one second channel 36 jointly on this.Wherein, this side wall 34 has a perforate 38.
3rd rail 14 is these second rails 12 that are slidably connected.
This holder 16 is the end 30b being fixedly mounted in this first rail 10 adjacent, and this holder 16 is positioned at the first passage 28 of this first rail 10, and this holder 16 comprises a pair arm 40, and this defines a grasping part 42 to arm 40.
This guide seat 18 is the side walls 26 being arranged at this first rail 10, and this guide seat 18 is the first passages 28 being positioned at this first rail 10.As shown in Figure 2, this guide seat 18 has a pair longitudinal guidance part 44 and a stopper 46, wherein, this defines a guide path 48 to longitudinal guidance part 44 and a guiding entrance 50 communicates with this guide path 48, and each longitudinal guidance part 44 has a surface 52 and is positioned at this guide path 48 and this guiding entrance 50.In detail, this in this guide path 48 defines one first width W 1 between the surface 52 of longitudinal guidance part 44.Definition one second width W 2 between this of this guiding entrance 50 is to the surface 52 of longitudinal guidance part 44.
As shown in Figure 3, this first contact 20 is the side walls 34 being arranged at this second rail 12, this first contact 20 comprises a pair first contact sites 54 and a pair second contact sites 56 connect this to the first contact site 54, and wherein, this is through the perforate 38 of this second rail 12 to the second contact site 56.Consult shown in Fig. 2, this also corresponds to the guiding entrance 50 of this guide seat 18 to the second contact site 56 again.In a preferred embodiment, this forms a V-shaped to the first contact site 54, this has surface 58 in opposite directions to the second contact site 56, one the 3rd width W 3 is defined between this effects on surface 58,3rd width W 3 is first width W 1 of this guide path 48 being greater than this guide seat 18, but is less than the second width W 2 of this guiding entrance 50 of this guide seat 18.Preferably, this second contact site 56 has the guiding entrance 50 that an inclined-plane 57 corresponds to this guide seat 18, this second contact site 56 is easy to guide by this guide seat 18.
This second contact 22 is arranged at the 3rd rail 14, and this second contact 22 comprises counter-lateral quadrents 60 and a protuberance 62, and wherein, this counter-lateral quadrents 60 corresponds to this of this first contact 20 to the first contact site 54.This protuberance 62 is the grasping parts 42 corresponding to this holder 16.Preferably, as shown in Figure 4, one the 4th width W 4 is defined between this counter-lateral quadrents 60.As shown in Figure 5, this of this first contact 20 defines one the 5th width W 5 to the first contact site 54, and the 5th width W 5 is suitable with the 4th width W 4 haply.
Fig. 6 shows the slide rail assembly of the embodiment of the present invention when a collapse state, this second contact 22 is that position is between this first contact 20 and this holder 16, and the protuberance 62 of this second contact 22 inserts in the grasping part 42 of this holder 16, and with this of this holder 16, arm 40 is clamped to the protuberance 62 of this first contact 22, make this slide rail assembly can remain on this collapse state, to avoid because tilting to make the 3rd rail 14 have the anxiety skidded off from this second rail 12.
Fig. 7 and Fig. 8 a shows when the 3rd rail 14 this first rail 10 relative is drawn out, in detail, a part for 3rd rail 14 is drawn out the front end 30a crossing this first rail 10, this second contact 22 departs from the grasping part 42 of this holder 16, and this second contact 22 synchronously this first contact 20 of pushing and pressing, this second rail 12 is drawn out and synchronous shift along with the 3rd rail 14.
Fig. 8 b shows this first contact 20 and pushes against with this second contact 22 and be moved to this guide seat 18, and a part for the second contact site 56 of this first contact 20 enters the guiding entrance 50 of this guide seat 18.Consult Fig. 2 and Fig. 3 again, due to the first width W 1 that this is the guide paths 48 being greater than this guide seat 18 to the 3rd width W 3 between the second contact site 56, but be less than the second width W 2 of the guiding entrance 50 of this guide seat 18, therefore, when being promoted to be moved to a precalculated position by this second contact 22 along with this first contact 20 is lasting, Fig. 9 a shows this first contact 20 further and can enter in the guide path 48 of this guide seat 18 via the guiding entrance 50 of this guide seat 18, and be butted on the stopper 46 of this guide seat 18, and, this of this first contact 20 is also guided with the guide path 48 of this guide seat 18 the second contact site 56 and is extruded displacement in opposite directions, make this first contact 20 this to the first contact site 54 locking phase to being extruded displacement.
Fig. 9 a and Figure 10 shows the 3rd rail 14 when continuing to be drawn out, this counter-lateral quadrents 60 of this second contact 22 is because this no longer contacting this first contact 20 is to the first contact site 54, namely this second rail 12 is no longer synchronously driven displacement along with the 3rd rail 14, and this second rail 12 rests on this guide seat 18 with this first contact 20, make this second rail 12 this first rail 10 relative launch a so far position and namely stop.Therefore, the 3rd rail 14 still can continue to be drawn out by this second rail 12 relatively.
When the 3rd rail 14 this first rail 10 relative folds from an expanded position, 3rd rail 14 meeting this second rail 12 displacement relatively, until after this second contact 22 crosses this first contact 20, as shown in figure 11, this second rail 12 is continuous when being pushed that this first rail 10 folds relatively, namely this first contact 20 departs from from this guide seat 18, after the 3rd rail 14 and this second rail 12 this first rail 10 relative fold completely, namely replys state as shown in Figure 6.
According to above explanation, namely known enhancement effect of the present invention and advantage are:
A., when slide rail is drawn out, there is two slide rails to be synchronously drawn out, and there is preferably support effect.
B. slide rail assembly can bear higher load.
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.
