Specific embodiment
Fig. 1 shows that the sliding rail assembly of the embodiment of the present invention includes one first rail 10, one second rail 12, one the 3rd rail 14,
Fixed seat 16, a guide seat 18, one first contact 20 and one second contact 22.
This first rail 10 comprise wall 24a on, once wall 24b and a side wall 26 extend be connected on this wall 24a with should
Between lower wall 24b, wall 24a, this lower wall 24b and this side wall 26 common definition one first passage 28 on this.Wherein, this side wall 26
There is an a front end 30a and end 30b.
This second rail 12 is this first rail 10 that is slidably connected, this second rail 12 also comprise 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 on this
Common definition one second channel 36.Wherein, this side wall 34 has a perforate 38.
3rd rail 14 is this second rail 12 that is slidably connected.
This fixed seat 16 is to be fixedly mounted in the end 30b of this first rail 10 adjacent, and this fixed seat 16 be located at this
In the first passage 28 of one rail 10, this fixed seat 16 includes a pair of arm 40, and this defines a grasping part 42 to arm 40.
This guide seat 18 is disposed on the side wall 26 of this first rail 10, and this guide seat 18 is in the of this first rail 10
In one passage 28.As shown in Fig. 2 this guide seat 18 has a pair longitudinal guidance part 44 and a stopper 46, wherein, this is led to longitudinal
Draw portion 44 definition one guide path 48 and a guiding entrance 50 is communicated with this guide path 48, each longitudinal guidance part 44 has one
Surface 52 is located in this guide path 48 and this guiding entrance 50.In detail, this in this guide path 48 is to longitudinal direction
One first width W1 is defined between the surface 52 of guidance part 44.This surface to longitudinal guidance part 44 positioned at this guiding entrance 50
One second width W2 is defined between 52.
As shown in figure 3, this first contact 20 is disposed on the side wall 34 of 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 to the second contact site 56
It is the perforate 38 through this second rail 12.Referring again to shown in Fig. 2, this to the second contact site 56 and corresponds to leading of this guide seat 18
Intake 50.In a preferred embodiment, this constitutes a V-shaped to the first contact site 54, and this has phase to the second contact site 56
To surface 58,, to defining one the 3rd width W3 between surface 58, the 3rd width W3 is greater than this of this guide seat 18 and leads for this
Lead the way the first width W1 in footpath 48, but the second width W2 of this guiding entrance 50 less than 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, so that this second contact site 56 is easy to by this guiding
Seat 18 is guided.
This second contact 22 is disposed on the 3rd rail 14, and it is prominent that this second contact 22 comprises a counter-lateral quadrents 60 and
Portion 62, wherein, this counter-lateral quadrents 60 correspond to this first contact 20 this to the first contact site 54.This protuberance 62 is corresponding
Grasping part 42 in this fixed seat 16.Preferably, as shown in figure 4, defining one the 4th width W4 between this counter-lateral quadrents 60.As figure
Shown in 5, this first contact 20 this to the first contact site 54 define one the 5th width W5, and the 5th width W5 generally with
4th width W4 is suitable.
Fig. 6 shows the sliding rail assembly of the embodiment of the present invention in a collapse state, this second contact 22 be position this
Between one contact 20 and this fixed seat 16, and the protuberance 62 of this second contact 22 is the clamping sky inserting this fixed seat 16
Between in 42, and this with this fixed seat 16 clamps protuberance 62 of this first contact 22 to arm 40, enables this sliding rail assembly
It is maintained at this collapse state, to avoid making the 3rd rail 14 have the anxiety skidding off from this second rail 12 because of inclination.
Fig. 7 and Fig. 8 a shows when this first rail 10 is drawn out the 3rd rail 14 relatively, in detail, the 3rd rail 14
A part is drawn out the front end 30a crossing this first rail 10, and this second contact 22 is from the grasping part 42 of this fixed seat 16
Depart from, and this synchronous this first contact 20 of pushing and pressing of the second contact 22, so that this second rail 12 is drawn out with the 3rd rail 14
And synchronous shift.
Fig. 8 b shows that this first contact 20 pushes against with this second contact 22 and is moved to this guide seat 18, and this
The guiding entrance 50 being partly into this guide seat 18 of the second contact site 56 of one contact 20.Referring again to Fig. 2 and Fig. 3, by
In this, the 3rd width W3 between the second contact site 56 is greater than with the first width W1 of the guide path 48 of this guide seat 18, but
Less than the second width W2 of the guiding entrance 50 of this guide seat 18, therefore, continue second to be connect by this with this first contact 20
Contact element 22 promotes when being moved to a precalculated position, and Fig. 9 a shows that this first contact 20 can leading via this guide seat 18 further
Intake 50 enters in the guide path 48 of this guide seat 18, and is butted on the stopper 46 of this guide seat 18, and, this first connects
This of contact element 20 is also directed to the guide path 48 of this guide seat 18 to the second contact site 56 and is extruded displacement in opposite directions, makes
This of this first contact 20 is extruded displacement in opposite directions to the first contact site 54 synchronization.
When Fig. 9 a and Figure 10 shows that the 3rd rail 14 is persistently drawn out, this counter-lateral quadrents 60 of this second contact 22 is because no longer
Contact this first contact 20 this to the first contact site 54, this second rail 12 is i.e. synchronous no longer with the 3rd rail 14 to be carried
Dynamic displacement, and this second rail 12 rests on this guide seat 18 with this first contact 20, make this second rail 12 relatively this first
Rail 10 launches a so far position and stops.Therefore, the 3rd rail 14 still can this second rail 12 relatively persistently be drawn out.
When this first rail 10 folds the 3rd rail 14 from an expanded position relatively, the 3rd rail 14 can this second rail relative
12 displacements, after this second contact 22 crosses this first contact 20, as shown in figure 11, this second rail 12 continues by promotion phase
When this first rail 10 is folded, this first contact 20 departs from from this guide seat 18, when the 3rd rail 14 and this second rail 12
After this first rail 10 folds completely relatively, that is, reply state as shown in Figure 6.
According to above explanation it is known that enhancement effect of the present invention is with advantage：
A., when slide rail is drawn out, there are two slide rails to be synchronously drawn out, and there is preferably support effect.
B. sliding rail assembly can bear higher load.
Although the present invention to describe with reference to current specific embodiment, those of ordinary skill in the art
It should be appreciated that above embodiment is intended merely to the present invention is described, also can make in the case of without departing from present invention spirit
Go out various equivalent changing and modifications, therefore, as long as to the change of above-described embodiment, change in the spirit of the present invention
Type all will fall in the range of the application claims.
