Clutch shaft bearing (120) is placed in outer side track main body (111), and now, a part for ball (129) is contained in raceway (113).
Intermediate orbit main body (131) is comprised at intermediate orbit (130).
In the both sides of intermediate orbit main body (131), as shown in the figure, the pair of flanges (132) to equidirectional bending centered by the length direction of intermediate orbit main body (131) is formed.In this pair of flanges (132), be formed with inboard raceways (133) and outboard raceway (134) respectively.
Outboard raceway (134) can be formed protrude from the outside of flange (132) towards the direction inner towards intermediate orbit main body (131), namely, from the outside of flange (132), protrude to the imaginary center line direction that the mid portion in intermediate orbit main body (131) marks along its length.
In this outboard raceway (134), accommodate a part for multiple balls (129) of clutch shaft bearing (120) respectively.Therefore, if intermediate orbit main body (131) is placed in outer side track main body (111), then with the shape configuration between guard ring (121) between rail body (131) and outer side track main body (111), ball (129) is contained in the raceway (113) of outer side track main body (111) and the outboard raceway (134) of intermediate orbit main body (131) and Structure deformation, thus outer side track main body (111) and intermediate orbit main body (131) can be slided relative to successfully and moved.
Inboard raceways (133) is formed protrude on the contrary with outboard raceway (134), and inboard raceways (133) is formed and makes to be held respectively by multiple balls (149) of the second bearing (140) illustrated below.
In addition, in intermediate orbit main body (131), can be formed for limiting below by the stop (135) of the moving range of the inner track main body (151) of explanation, stop (135) can be formed in the pull-out direction of intermediate orbit main body (131) (A) end.
Guard ring (141) and ball (149) can be comprised in the second bearing (140).
In the both sides of the edge of guard ring (141), as shown in the figure, be formed with the pair of flanges (142) to equidirectional bending shape centered by the length direction of guard ring (141), on flange (142), be formed with multiple ball insertion hole (143) along its length.In multiple ball insertion hole (143), multiple ball (149) can be inserted one by one.
Second bearing (140) is placed in intermediate orbit main body (131), and now, a part for multiple ball (149) is contained in inboard raceways (133).
Inner track main body (151) and buffer (159) is comprised in inner track (150).
In the both sides of inner track main body (151), as shown in the figure, the pair of flanges (152) to equidirectional bending centered by the length direction of inner track main body (151) is formed.In this pair of flanges (152), be formed with raceway (153) along its length respectively, this raceway (153) is formed to hold the parts of ball (149).
Therefore, if inner track main body (151) is placed in intermediate orbit main body (131), then with the shape configuration between guard ring (141) between rail body (131) and inner track main body (151), between the raceway (153) that multiple ball (149) is contained in inboard raceways (133) and inner track main body (151) and Structure deformation, thus intermediate orbit main body (131) and inner track main body (151) can be slided relative to successfully and moved.
In inner track main body (151), stop (156) can be formed, described stop (156) connects with stop described above (135), limits inner track main body (151) relative to intermediate orbit main body (131) to the scope pushing direction (B) slip movement.This stop (156) as shown in the figure, can be formed in the pull-out direction of inner track main body (151) (A) end.
Contingent impact when buffer (159) is for relaxing stop (135) contact of the stop (135) of inner track main body (151) and intermediate orbit main body (131) noise decrease, can with elastomeric material manufacture, as shown in the figure, be incorporated into stop (156), although not shown, stop (135) also can be incorporated into.

As mentioned above, outer side track main body (111) can be combined to obtain with inner track main body (151) movement of relatively sliding with intermediate orbit main body (131) and intermediate orbit main body (131) respectively, and this slip movement successfully can embody by means of clutch shaft bearing (120) and the second bearing (140).
As a reference, if intermediate orbit main body (131) is slided mobile to pull-out direction (A) relative to outer side track main body (111), so, along with multiple ball (129) rotates between raceway (113) and outboard raceway (134), guard ring (121) also moves to the direction of intermediate orbit main body (131) movement.
In the process, if intermediate orbit main body (131) arrives the boundary relative to the moveable scope of outer side track main body (111), the stop support (125) then formed on guard ring (121) and stop (115) connect mutually, therefore guard ring (121) cannot move again, so intermediate orbit main body (131) is no longer mobile to pull-out direction (A) relative to outer side track main body (111).
Similarly, if contact at the upper stop (135) formed of intermediate orbit main body (131) the stop support (146) formed in pull-out direction (A) end of guard ring (141), or at the stop support (145) that push direction (B) end formation of upper stop (155) contact formed of inner track main body (151) at guard ring (141), so, inner track main body (151) is no longer mobile to pull-out direction (A) relative to intermediate orbit main body (131).
On the other hand, push direction (B) side in inner track main body (151), running block (160) can be combined with.Now, the block (160) that operates is configured at the face towards intermediate orbit main body (131) of inner track main body (151).

Now, an end portion of running pin (250) is in the state inserting line part (212a), and the pin (250) that thus operates does not move along the length direction of pin-and-hole (231).Therefore, under being positioned in the other end of running pin (250) the state linking groove (162), the other end of running pin (250) is linked to and links groove (162), is not separated from running block main body (161).
In this state, if user makes drawer (12) mobile to pull-out direction (A) to open drawer (12), so, the inner track main body (151) being incorporated into drawer (12) is mobile to pull-out direction (A).Now, running pin (250) is in the state being linked to and linking groove (162), therefore, the movement of the inner track main body (151) combined along with running block main body (161), slider (230) is pull-out direction (A) movement in the same way also.
Therefore, the elastomer (270) that shut-off block main body (210) and slider (230) are fixed in both ends stretches, and slider (230) is by shut-off block main body (210) direction elastic bearing.That is, if make inner track main body (151) remove to the power of pull-out direction (A) movement, then inner track main body (151) can return to the state shown in Fig. 5.
On the other hand, along with slider (230) is to the movement of pull-out direction (A), intermediate orbit main body (131) is by push rod (233) pressurization, and pull-out direction (A) is mobile in the same way with inner track main body (151).
In figure 6, illustrate at drawer (12 of Fig. 1) in the process of pull-out direction (A) movement, the connecting state of inner track main body (151) and slider (230) is by the state removed.
As shown in Figure 6, the pin (250) that operates is linked to the state linking groove (162) and is removed.
As previously described, continue in the process of pull-out direction (A) movement at drawer (12), slider (230) arrives to the position of bend (212b), guided by line part (212a), once linearly an end of portion (212a) and the running pin (250) of movement was bent portion (212b) guiding.Therefore, the other end of running pin (250) is along the marginal portion at the upper link groove (162) formed of running block main body (161), move to the end of the bend (212b) of pin-and-hole (231), so the other end of running pin (250) departs from from link groove (162).
The other end of running pin (250) is after link groove (162) disengaging, connection between inner track main body (151) and slider (230) is removed, therefore, the power that drawer (12) is pulled out putting on inner track main body (151) is not transmitted to slider (230).
Before until operate, pin (250) departs from from link groove (162), slider (230) is mobile to pull-out direction (A) with inner track main body (151), therefore, with the intermediate orbit main body (131) of being pressurizeed by push rod (233) or inner track main body (151) pull-out direction (A) movement in the same way.
Now, slider (230) is in the state that running pin (250) one ends are linked to the end of bend (212b).Namely, in the other end of running pin (250), apply towards the power in the direction of line part (212a) and bend (212b) link position, before until operate, an end of pin (250) returns line part (212a), slider (230) keeps in touch the state of pull-out direction (A) end of running rails (211).
In the figure 7, inner track main body (151) and intermediate orbit main body (131) is illustrated together further to the state of pull-out direction (A) movement.
As previously described, if inner track main body (151) starts mobile to pull-out direction (A) from the position that drawer (12) is closed, so, pull-out direction (A) is mobile in the same way for inner track main body (151), slider (230) and intermediate orbit main body (131).
In the process, slider (230) arrives the boundary of mobile range, that is, after the end that arriving operates sells (250) is connected to the position of bend (212b), the mobile of slider (230) stops.After the mobile stopping of slider (230), intermediate orbit main body (131) is removed with the contact of push rod (233), no longer pressurizes.
However, after intermediate orbit main body (131) starts and inner track main body (151) together moves, even if intermediate orbit main body (131) is not pressurizeed by push rod (233), as shown in the figure, intermediate orbit main body (131) also can to once with the direction of inner track main body (151) together movement, that is, mobile to pull-out direction (A).
This is because caused by the difference in size acting on the coefficient of friction between the inertia of the intermediate orbit main body (131) of movement and inner track main body (151), intermediate orbit main body (131) and outer side track main body (111), be explained with reference to Fig. 8.
In fig. 8, the schematic cross sectional view of the E part identified in Fig. 6 is illustrated.
As shown in Figure 8, the ball (129 of Fig. 2) of clutch shaft bearing (120 of Fig. 2) is between the flange (112) of outer side track main body (111) and the flange (132) of intermediate orbit main body (131), and the ball (149 of Fig. 2) of the second bearing (140 of Fig. 2) is between the flange (132) of rail body (131) and the flange (152) of inner track main body (151).
The ball (129) of clutch shaft bearing (120 of Fig. 2) is configured in the upper ball insertion hole (123) formed of the flange (122) of guard ring (121 of Fig. 2), and the ball (149) of the second bearing (140 of Fig. 2) is configured in the upper ball insertion hole (149) formed of the flange (142) of guard ring (141 of Fig. 2).
Wherein, ball insertion hole (123,143) internal diameter is generally formed than ball (129,149) external diameter is large, but in the process that drawer (12) pulls out or pushes, outer side track main body (111), intermediate orbit main body (131) and inner track main body (151) relative sliding move, therefore, ball (129,149) certain part in surface generally contacts a part for the inner peripheral surface of ball insertion hole (123,143).
As above with reference to Fig. 5 to Fig. 7 description, if drawer (12 of Fig. 1) starts mobile from the position closed to pull-out direction (A), so, be fixed on the inner track main body (151) of drawer (12), be in by running pin (250) be linked to inner track main body (151) state slider (230), contact from slider (230) protrude formed push rod (233) and together move pressurized intermediate orbit main body (131).
The Vi identified in figure represents the translational speed of inner track main body (151), Vm represents the translational speed of intermediate orbit main body (131), because inner track main body (151) and intermediate orbit main body (131) together move, therefore, Vi and Vm has identical size.
Wherein, in the inner track main body (151) being fixed on drawer (12), not only be applied with the heavy burden of drawer (12) self, but also the heavy burden of the collecting article held in being applied with drawer (12), this heavy burden passes to intermediate orbit main body (131) by ball (149).
Therefore, from after middle rail body (131) starts together to move with inner track main body (151), the inertia force produced because of motion acts on intermediate orbit main body (131) and inner track main body (151), until before putting on intermediate orbit main body (131) and inner track main body (151) with the rightabout external force in the direction of movement, the state of together movement can continue.
In addition, as previously described, relative movement is there is not between inner track main body (151) and intermediate orbit main body (131), therefore, ball (149) non rotating between the flange (132) of rail body (131) and the flange (152) of inner track main body (151).Therefore, on the surface of non-rotary ball (149), friction of rest power acts on, and on the surface of the ball (129) rotated, kinetic friction force acts on.
Kinematic friction coefficient is less than coefficient of friction of rest all the time, and this is the known fact.Therefore, act on the coefficient of friction of rest of the friction of rest power of the ball (149) of the second bearing (140), be greater than the kinematic friction coefficient of the kinetic friction force of the ball (129) acting on clutch shaft bearing (120), so, according to the difference of this coefficient of friction, by means of push rod (233) with the intermediate orbit main body (131) of inner track main body (151) together movement after removing the contact with push rod (233), the state with inner track main body (151) together movement can also be kept.
As above description, in the process that the drawer (12) of closing pulls out to open, intermediate orbit main body (131) is pressurizeed by push rod (233), together move with inner track main body (151), even if exceeding the operating range of slider (230), after push rod (233) no longer pressurizes, by means of the difference of the inertia force illustrated above and coefficient of friction, intermediate orbit main body (131) keeps the state with inner track main body (151) together movement.
Intermediate orbit main body (131) and inner track main body (151) together move, until the boundary of the scope of relative sliding movement can be carried out relative to outer side track main body (111), afterwards, the mobile of intermediate orbit main body (131) stops, and it is mobile that inner track main body (151) carries out slip relative to intermediate orbit main body (131).
Therefore, in the process that the sliding rail for drawer device (1) of first embodiment of the invention pulls out at the drawer (12) of closing, inner track main body (151) and intermediate orbit main body (131) in the same way pull-out direction (A) are mobile, and this state continues to pull-out direction (A) movable range of intermediate orbit main body (131).
Therefore, the sliding rail for drawer device (1) of first embodiment of the invention makes when drawer (12) pulls out, intermediate orbit (130 of Fig. 1) and inner track (150 of Fig. 1) together move, thus the heavy burden supporting force of carriage (100 of Fig. 1) is improved, drawer (12) can be made to pull out smoothly, can make in the pull-out process of drawer (12), carriage (100) is unduly sagging or noise does not occur.The intermediate orbit (not shown) being different from common triple carriage (not shown)s only operates completely passively, this is the running that the sliding rail for drawer device (1) of first embodiment of the invention makes to regulate by means of automatic shut-off block (200) intermediate orbit (130), thus the effect that can obtain.
In Fig. 9 to Figure 11, illustrate the figure of the running of the sliding rail for drawer device for illustration of second embodiment of the invention.
In fig .9, the appearance during drawer closed condition of the sliding rail for drawer device of second embodiment of the invention is illustrated.
As shown in Figure 9, at the side end towards shut-off block main body (210) of intermediate orbit main body (131), that is, pushing direction (B) end, be formed with cut (139).Cut (139) is formed with following size, under the state that drawer (12) is closed, namely, intermediate orbit main body (131) be in movable range to when pushing the state of the position of movement to greatest extent, direction (B), the size of cut (139) can hold running rails (211).
Therefore, the part not forming cut (139) pushed in direction (B) end of intermediate orbit main body (131), connects with slider (230).
In Fig. 10, illustrate at drawer (12 of Fig. 1) in the process of pull-out direction (A) movement, the connecting state of inner track main body (151) and slider (230) is by the state removed.
As shown in Figure 10, the pin (250) that operates is linked to the state linking groove (162) and is removed.Running pin (250) is linked to the process of the status releasing linking groove (162), and identical with the content illustrated with reference to Fig. 6, thus the repetitive description thereof will be omitted.
But, with regard to the sliding rail for drawer device of second embodiment of the invention, removed until running pin (250) is linked to the state linking groove (162), the part contact slider (230) not forming cut (139) pushed in direction (B) end of intermediate orbit main body (131), is pressurizeed to pull-out direction (A) by slider (230).
Therefore, pull-out direction (A) is mobile in the same way for intermediate orbit main body (131) and inner track main body (151).
In fig. 11, the inner track main body (151) of the sliding rail for drawer device of second embodiment of the invention and intermediate orbit main body (131) state to pull-out direction (A) movement is further illustrated.
By means of the inertia once illustrated with reference to Fig. 8 above and the difference of coefficient of friction, even if the part not forming cut (139) pushed in direction (B) end of intermediate orbit main body (131) is removed with the contact of slider (230), no longer to pull-out direction (A) pressurization, intermediate orbit main body (131) also can pull-out direction (A) be mobile in the same way with inner track main body (151).
The sliding rail for drawer device of this second embodiment of the invention, except the effect that the sliding rail for drawer device (1 of Fig. 1) of the first embodiment of the invention once illustrated with reference to Fig. 8 has, as shown in Figure 9, cut (139) is formed have and the corresponding length of running rails (211) length (D1), therefore, the length changing running rails (211) as required manufactures, and can obtain the effect of the operating range regulating automatic shut-off block.That is, as required, can make when drawer (12) to push direction (B) mobile time, the scope that can realize automatically closing extends or shortens.
In addition, with regard to the sliding rail for drawer device of second embodiment of the invention, the extension D1 of intermediate orbit main body (131), thus drawer (12) heavy burden of intermediate orbit main body (131) is delivered to by inner track main body (151), also extended by the length that outer side track main body (111) supports, therefore, the effect of the structural strength of the sliding rail for drawer device increasing second embodiment of the invention can also be obtained.
Illustrate the automatic shut-off block of the sliding rail for drawer device of third embodiment of the invention in fig. 12, in Figure 13 to Figure 15, illustrate the figure of the running of the sliding rail for drawer device for illustration of third embodiment of the invention.
As shown in figure 12, the automatic shut-off block of the sliding rail for drawer device of third embodiment of the invention, compared with the automatic shut-off block (200 of Fig. 3) illustrated with reference to Fig. 3 and Fig. 4, the thickness (t) of running rails (211a) is different, be formed with holddown groove (218), form buffer part (234) and replace push rod (233 of Fig. 3), formation is in addition identical, and thus the repetitive description thereof will be omitted.
If together with reference to Figure 12 and Figure 13, the thickness (t) of the running rails (211a) possessed in the automatic shut-off block of the sliding rail for drawer device of third embodiment of the invention, namely, running rails (211a) from as outer side track main body (111) another side towards intermediate orbit main body (113) although the height that protrudes of face be not shown specifically, formed lower than the interval formed between the another side and intermediate orbit main body (113) of outer side track main body (111).
Therefore, when drawer (12 of Fig. 1) close, intermediate orbit main body (131) is in when pushing the state of direction (B) movement to greatest extent, intermediate orbit main body (131) push direction (B) part as shown in figure 13, the pull-out direction (A) of running rails (211a) part can be covered by intermediate orbit main body (131).That is, when drawer (12) pushes, when being in closed condition, pull-out direction (A) part of running rails (211a) can be positioned between outer side track main body (111) and intermediate orbit main body (131).
So, realize to make the thickness (t) of running rails (211a) minimizing, having making the degree of depth of guiding groove (212) in the scope of the height that can guide running pin (250) one ends smoothly, the thickness (t) of running rails (211a) can be made to realize minimizing.
As a reference, although not shown, but in the part being configured with running rails (211a) of outer side track main body (111), be formed through the patchhole had with running rails (211a) respective shapes, if make running rails (211a) insert this patchhole, then corresponding to the thickness of outer side track main body (111), the thickness (t) of running rails (211a) can be guaranteed.Namely, running rails (211a) is made to insert not shown patchhole, thus running rails (211a) does not increase from the height protruded towards the face of intermediate orbit main body (113) of outer side track main body (111), meanwhile, the thickness (t) of running rails (211a) correspondingly can increase with the height of patchhole.Therefore, the guiding groove of running rails (211a) (212) can be made to have sufficient height.
In addition, make running rails (211a) insert not shown patchhole, thus the space that the automatic shut-off block of the sliding rail for drawer device of third embodiment of the invention occupies can realize minimizing.

As mentioned above, by the thickness (t) of running rails (211a) is formed lower, as previously described, even if do not form cut (139 of Fig. 9) in intermediate orbit main body (131), or on slider (230), do not form push rod (Fig. 3 233), also can make intermediate orbit main body (131) contact slide device (230).
In the part that slider (230) connects with intermediate orbit main body (131), buffer part (234) can be formed with.Buffer part (234) can make the collision because of slider (230) and intermediate orbit main body (131) and the impact caused or noise are relaxed.Wherein, buffer part (234) as shown in the figure, can be made up of the buffering projection protruded from slider (230), although not shown, also can be incorporated into intermediate orbit main body (131) by the buffer component manufactured with elastomeric material and formed.
As shown in figure 14, the pin (250) that operates is linked to the state linking groove (162) and is removed.Running pin (250) is linked to the state of link groove (162) by the process removed, and identical with the content illustrated with reference to Fig. 6, thus the repetitive description thereof will be omitted.
With regard to the sliding rail for drawer device of third embodiment of the invention, until running pin (250) be linked to link groove (162) state removed till, intermediate orbit main body (131) push direction (B) ends contact slider (230).Therefore, intermediate orbit main body (131) is by carriage (230) to pull-out direction (A) pressurization, and pull-out direction (A) is mobile in the same way with inner track main body (151).
As shown in figure 15, the inner track main body (151) of the sliding rail for drawer device of third embodiment of the invention and intermediate orbit main body (131) are to pull-out direction (A) movement further.
By means of the inertia once illustrated with reference to Fig. 8 above and the difference of coefficient of friction, even if intermediate orbit main body (131) is removed with the contact of slider (230), no longer to pull-out direction (A) pressurization, intermediate orbit main body (131) also can pull-out direction (A) be mobile in the same way with inner track main body (151).
The sliding rail for drawer device of this third embodiment of the invention is compared with the sliding rail for drawer device of the second embodiment of the invention once illustrated above, and the structural strength that can obtain intermediate orbit main body (131) does not reduce and the operating range of shut-off block obtains the effect that extends automatically.That is, the intermediate orbit main body (131) of the sliding rail for drawer device of third embodiment of the invention does not form cut (139 of Fig. 9), the intensity that intermediate orbit main body (131) thus correspondingly can not occur reduces.
And, as shown in figure 13, with regard to the sliding rail for drawer device of third embodiment of the invention, because the length of intermediate orbit main body (131) does not have an impact to the length (D2) of running rails (211a) completely, therefore, the length changing running rails (211a) as required manufactures, and can obtain the effect of the operating range regulating automatic shut-off block.That is, as required, can make when drawer (12) to push direction (B) mobile time, the scope that can realize automatically closing extends or shortens.
