Fig. 4 a, Fig. 4 b and Fig. 4 c are the graphs of a relation of the above-mentioned maintenance pin 30 of expression, pin guide member 32 and cam part 33, Fig. 4 b be the B of Fig. 4 a to view, Fig. 4 c is that the C of Fig. 4 b is to view.In these figure, above-mentioned pin guide member 32 is that synthetic resin is made, have front board 32a, a pair of foot section 32b, the 32b that give prominence to from the both sides of this front board 32a and pass through this foot section 32b and above-mentioned front board 32a opposing backside surface board 32c, back side board is fixed on the outer rail 1.Form the space between front board 32a and back side board 32c, this space becomes the mobile space of above-mentioned maintenance pin 30.On the board 32a of this front, form the guiding groove 60 that the above-mentioned maintenance pin 30 of restriction moves, keep the front end of pin 30 to be inserted into guiding groove 60, outstanding towards cam part 33.On the other hand, above-mentioned maintenance pin 30 has discoidal base portion 30a, and this base portion 30a is sandwiched between the front board 32a of back side board 32c and pin guide member 32.Therefore, keep pin 30 making under its front end state outstanding, can move freely with respect to outer rail 1, in case external force to this front end effect, then will move in guiding groove 60 according to its direction from above-mentioned guiding groove 60.In addition, as shown in Figure 5, this pin guide member 32 also can form by crooked metal sheet, can save back side board 32c in this case, as shown in Figure 1, foot section 32b directly can be fixed on the outer rail 1.
And, on the base portion 30a of above-mentioned maintenance pin 30, fix a end as the extension spring 31 of elastomeric element, the other end of this extension spring 31 is fixed on the double-screw bolt 32c that is arranged on the above-mentioned pin guide member 32.This double-screw bolt 32c is positioned at the end side of outer rail 1 with respect to guiding groove 60.Keep pin 30 can be arranged on any position of guiding groove 60, above-mentioned extension spring 31 is in the state of elongation, at the active force that keeps extension spring 31 on the pin 30 always towards the end direction of outer rail 1, promptly in rail 2 draw in directive effect.
On the other hand, above-mentioned guiding groove 60 have that the active force that is used to resist extension spring 31, fastening keep the fastening recess 61 of pin 30 and from this fastening recess 61 continuously and along the stretching guide portion 62 of vertical formation of outer rail 1.Above-mentioned fastening recess 61 is at the position of readiness of interior rail 2 being set above-mentioned maintenance pin 30 when outer rail 1 is pulled out, when keeping pin 30 to be set on the fastening recess 61, above-mentioned extension spring 31 be in stretch the longest state.Therefore, in case owing to the action of cam part 33 described later, the fastening recesses 61 that keep pin 30 to break away from as position of readiness, then should keep pin 30 on above-mentioned stretching guide portion 62, to move, up to the terminal that moves to this stretching guide portion 62 by active force one gas of extension spring 31.
And, form in the end with the approaching stretching guide portion 62 of above-mentioned double-screw bolt 32c and to keep out of the way recess 63, this is kept out of the way recess 63 and will irrespectively break away from the maintenance pin 30 of position of readiness (fastening recess 61), use when being set on this position of readiness once more with moving of the cam part 33 of interior rail 2 sides.This is kept out of the way recess 63 and forms in the mode that tilts to intersect with stretching guide portion 62.What this kept out of the way recess 63 specifically utilizes method as described later.
Below, the above-mentioned cam part 33 of rail 2 sides describes in just being arranged on.This cam part 33 cuts guiding groove 64 and forms on metallic plate, the medial surface of rail 2 in being fixed in the mode relative with the pin guide member 32 of outer rail 1 side.Above-mentioned guiding groove 64 is as constituting with respect to the so-called cam path that moving of outer rail 1 changes the desired location of above-mentioned maintenance pin 30 according to interior rail 2, has the introduction part 65, the maintenance pin 30 that makes income of front end that income is set in the maintenance pin 30 of position of readiness and moves and make its service portion that breaks away from above-mentioned position of readiness 66 and the fastening pin indwelling portion 67 by the maintenance pin 30 of this service portion 66 to the width of outer rail 1.This pin indwelling portion 67 is relative with the stretching guide portion 62 of pin guide member 32, keeps pin 30 can moved on above-mentioned stretching guide portion 62 under the state of pin indwelling portion 67 by fastening.
Shown in Fig. 4 c, pin guide member 32 and above-mentioned cam part 33 are relative mutually between outer rail and interior rail 2, and the front end of the maintenance pin of giving prominence to from pin guide member 32 30 inserts in the guiding groove 64 of above-mentioned cam part 33.Certainly, because being used to insert the structure of the guiding groove 64 of the front end that keeps pin 30, above-mentioned cam part 33 so long as have gets final product, therefore, might the cam part 33 that is formed with guiding groove 64 be fixed on fully on the interior rail 2, but as Fig. 1 and shown in Figure 6, installation portion 21 with respect to interior rail 2 directly forms guiding groove 64, should form the position and utilize as cam part 33.
The action of the above-mentioned maintenance pin 30 when Fig. 7 a to Fig. 7 f represents that according to time sequencing interior rail 2 drawn in outer rail 1.Shown in Fig. 7 a, interior rail 2 is pulled out from outer rail 1, under cam part 33 and the state that the guiding groove 60 of pin guide member 32 separates fully, above-mentioned maintenance pin 30 is set in position of readiness, is the fastening recess 61 of above-mentioned guiding groove 60.Under this state, the tensile force of elastomeric element 31 acts on and keeps on the pin 30, keeps pin 30 to enter fastening recess 61 and carries out fastening, keeps being set in the state on the position of readiness.At this, if interior rail 2 is drawn into outer rail 1, and such cam part 33 overlaps onto on the guiding groove 60 shown in Fig. 7 b, then keep pin 30 to enter in the guiding groove 63 from introduction part 65, if rail 1 in drawing in this state, then shown in Fig. 7 c, keep pin 30 will with service portion 66 butts.Because this service portion 66 is provided with obliquely with respect to the moving direction of interior rail, therefore, in case draw in interior rail with this state, then shown in Fig. 7 d, keep pin 30 will be partial to moving direction (the arrow line direction among the figure) the orthogonal direction of interior rail, from fastening recess (position of readiness) 61 disengagings of guiding groove 60.And, on the guiding groove 64 of cam part 33, keep pin 30 to enter pin indwelling portion 67 by service portion 66, this keep pin 30 in this pin indwelling portion 67 by fastening.
As mentioned above, because the pin indwelling portion 67 of cam part 33 is relative with the stretching guide portion 62 of guiding groove 60, therefore, shown in Fig. 7 e, in case will keep pin 30 to be set in the pin indwelling portion 67 of cam part 33, then, keep pin 30 to move in the direction of drawing in of the inside rail 2 in the one gas ground, inside of stretching guide portion 62 by the active force of elastomeric element 31.And at this moment, owing to keep pin 30 fastenings in the pin indwelling portion 67 of cam part 33, therefore, the stretching action power of elastomeric element 31 is by keeping pin 30 to cam part 33 and then inwardly rail 2 effects, and interior rail 2 is automatically drawn in the outer rail 1.Like this, shown in Fig. 7 f, interior rail 2 is pulled into the terminal location of stroke range, and the active force by elastomeric element 31 remains on this position.
Like this, in slide track component of the present invention, when interior rail 2 is drawn in outer rail 1, in case should arrive near the terminal of the trip scopes by interior rail 2, the then effect of the cam part 33 by interior rail 2 sides, keep pin 30 will break away from position of readiness,, interior rail 2 automatically can be drawn in the outer rail 1 keeping selling the active force one gas ground effect of 30 elastomeric elements 31 that act on.And, under the state of drawing in, because the active force of elastomeric element 31 is as the confining force effect, therefore, rail 2 is jumped out from outer rail 1 unintentionally in can preventing, for example, under the situation of the guide that slide track component is used for drawer, can eliminate the half-open position of this drawer.
On the other hand, with interior rail 2 when outer rail 1 is pulled out, keep pin 30 to be set on the position of readiness with the antipodal order of Fig. 7 a to Fig. 7 f.That is because under the state that keeps in the pin indwelling portion 67 of pin 30 fastenings at cam part 33, interior rail 2 is pulled out from outer rail 1, therefore, keep pin 30 opposing elastomeric elements 31 active force, stretching guide portion 62 is moved towards fastening recess 61.Because guiding groove 60 from stretching guide portion 62 to fastening recess 61, pull-out direction with respect to interior rail 2 is formed obliquely, therefore, in case further interior rail 2 is pulled out from outer rail 1, then this guiding groove 60 will act on keeping pin 30 as cam path, keep pin 30 deflections and the moving direction orthogonal of interior rail 2 direction, be set on the fastening recess 61.And the maintenance pin 30 of this moment breaks away from the pin indwelling portion 67 of cam part 33, arrives introduction part 65 (state of Fig. 7 c) through service portion 66.Like this, can make to keep pin 30 to break away from cam part 33, the cam part 33 of rail 2 sides separates from the pin guide member 32 of outer rail 1 side in making, and interior rail 2 can be pulled out from outer rail 1.And, keep pin 30 under the state that makes elastomeric element 31 elongations, to be set on the fastening recess (position of readiness) 61 of guiding groove 60, next, when drawing in interior rail 2 in the outer rail 1, rail 2 in can drawing in according to the order help of Fig. 7 a to Fig. 7 f again.
Like this, though usually under the state that interior rail 2 is pulled out from outer rail 1, keep pin 30 to be set on the fastening recess 61 of guiding groove 60, but because percussion is first-class in outer rail 1, will keep selling 30 situations about breaking away from from fastening recess 61 unintentionally, in this case, shown in Fig. 7 a, keep pin to fall into the terminal location of stretching guide portion 62.Keeping pin 30 to be set to unintentionally under the situation of such position, if will not keep pin 30 to reset into fastening recess 61, then this maintenance pin 30 will become obstacle, can not fully interior rail 2 be drawn in the outer rail 1.Therefore, in this slide track component, be provided with and keep pin 30 mechanisms that reset on the fastening recess (position of readiness) 61.
