FIG. 3 is an assembled view of the sliding mechanism shown inFIG. 1 . -
FIGS. 4-8 show the sliding mechanism shown inFIG. 3 in different states. - An exemplary embodiment of a sliding mechanism is shown in
FIGS. 1-3 . The sliding mechanism includes aninner rail 10, amiddle rail 30, anouter rail 50, and alatching assembly 60. Themiddle rail 30 is mounted between theinner rail 10 and theouter rail 50. Thelatching assembly 60 includes afirst protrusion 61, asecond protrusion 62, a first position member such as aroller 63, anelastic element 64, asliding groove 65, a resistingportion 655, and athird protrusion 66. Thefirst protrusion 61 and thesecond protrusion 62 are both positioned on theinner rail 10. Thesliding groove 65 and the resistingportion 655 are positioned on themiddle rail 30. Thethird protrusion 66 is positioned on theouter rail 50. - The
inner rail 10 includes twosliding plates 14 respectively located at opposite sides thereof. Thefirst protrusion 61 is substantially arcuate, including afirst protrusion valley 611 and afirst protrusion peak 613. Thefirst protrusion 61, in this exemplary embodiment, is positioned at one side of theinner rail 10 facing themiddle rail 30 and near one end of theinner rail 10. Thesecond protrusion 62 has substantially the same shape as, but is larger than thefirst protrusion 61, and thesecond protrusion 62 is situated at the same side as thefirst protrusion 61. Thesecond protrusion 62 is located at another end of theinner rail 10 and includes asecond protrusion valley 621 and asecond protrusion peak 623. - The
middle rail 30 includes two slidingblocks 34 respectively positioned at opposite sides thereof. The slidingblocks 34 are for slidably engaging with theouter rail 50 so theouter rail 50 can slide relative to themiddle rail 30. Each slidingblock 34 defines asliding groove 342 facing the other slidingblock 34. Each slidinggroove 342 slidably engages one of thesliding plates 14 to enable themiddle rail 30 to slide relative to theinner rail 10. Themiddle rail 30 further includes ahook 323 for latching theelastic element 64 to themiddle rail 30. Anopening 322 is defined through themiddle rail 30 and is used for allowing theelastic element 64 to pass through themiddle rail 30. - Referring to
FIG. 2 , the guidinggroove 65 is transversely defined through themiddle rail 30. The guidinggroove 65 is for guiding theroller 63 to slide relative to themiddle rail 30 in a direction substantially perpendicular to the sliding direction (an arrow shown inFIG. 5 ) of theinner rail 10. The guidinggroove 65 includes a guidinggroove valley 651 and a guidinggroove peak 652 that is larger than the guidinggroove valley 651. - The resisting
portion 655 protrudes from themiddle rail 30 toward theouter rail 50. The resistingportion 655 is for resisting theouter rail 50 so themiddle rail 30 and theouter rail 50 can slide together relative to theinner rail 10. - The
outer rail 50 has twosliding slots 52 respectively defined at opposite sides thereof. Each slidingslot 52 slidably engages with one of the slidingblocks 34 so theouter rail 50 can slide relative to themiddle rail 30. - Referring also to
FIG. 2 , thethird protrusion 66 is substantially arcuate, and includes athird protrusion valley 661 and athird protrusion peak 663 communicating with thethird protrusion valley 661. Thethird protrusion 66, in this exemplary embodiment, is positioned at one side of theouter rail 50 opposing themiddle rail 30 near one end of theouter rail 50. Theouter rail 50 further defines alatching slot 662 between thesecond protrusion valley 661 and thethird protrusion peak 663, which latches with theroller 63. Theouter rail 50 further includes astopping surface 664 located near thethird protrusion peak 663. The stoppingsurface 664 is for resisting against the resistingportion 655 so theouter rail 50 slides together with themiddle rail 30. - Referring also to
FIG. 2 , theroller 63 includes amain body 631, afirst pin 633 protruding from one side of themain body 631, asecond pin 635 protruding from another side of themain body 631. A retaining slot 637 defined around thefirst pin 633 near themain body 631 and asecuring slot 639 defined around thesecond pin 635 near themain body 631. Thefirst pin 633 slides along thefirst protrusion 61 when themiddle rail 30 slides relative to theinner rail 10. Thesecond pin 635 slides along thethird protrusion 66 when themiddle rail 30 slides relative to theouter rail 50. The retaining slot 637 is for retaining theelastic element 64 on theroller 63. Thesecuring slot 639 is for slidably securing with the portions of themiddle rail 30 surrounding the guidinggroove valley 651 so theroller 63 is slidably secured to themiddle rail 30. In this exemplary embodiment, thesecond pin 635 is smaller than the guidinggroove peak 652 so thesecond pin 635 can pass through the guidinggroove peak 652. Thesecond pin 635 is larger than the guidinggroove valley 651 to prevent thesecond pin 635 and themiddle rail 30 from separating when thesecond pin 635 is located in the guidinggroove valley 651. - The
elastic element 64 is V-shaped and includes alatching portion 641 formed at the center thereof, aninserting portion 642 is formed at one end thereof and aretaining ring 645 is formed at another end thereof. Thelatching portion 641 latches with thehook 323 to hold theelastic element 64 to themiddle rail 30. The insertingportion 642 is inserted in theopening 322 to assist theelastic element 64 to hold themiddle rail 30. The retainingring 645 wraps in the retaining slot 637 to latch theelastic element 64 to theroller 63. - Referring to
FIGS. 1-4 , in assembly, the insertingportion 642 passes through theopening 322 until the insertingportion 642 is located between the guidinggroove peak 652 and the guidinggroove valley 651. The latchingportion 641 latches with thehook 323 so theelastic element 64 is latched to themiddle rail 30. The retainingring 645 wraps in the retaining slot 637 to retain theroller 63 to theelastic element 64. Thesecond pin 635 passes through the guidinggroove peak 652 until the securingslot 639 is located in the guidinggroove peak 652. Then thesecond pin 635 slides to the guidinggroove valley 651 so the securingslot 639 slidably latches with the portion of themiddle rail 30 surrounding the guidinggroove valley 651. - Each sliding
plate 14 is slidably accommodated in one of the slidinggrooves 342 so theinner rail 10 is slidably mounted to themiddle rail 30. Referring toFIG. 4 , at this time, thesecond pin 635 is located near the guidinggroove peak 652 and thefirst pin 633 is located at thefirst protrusion peak 613 so theelastic element 64 is compressed. Finally, each slidingblock 34 is slidably accommodated in one of the slidingslots 52 so themiddle rail 30 is slidably mounted to theouter rail 50. At this stage, thesecond protrusion peak 623 is leveled with thethird protrusion peak 663 along a sliding direction of the sliding mechanism. - Referring to
FIG. 5 , in use, theinner rail 10 is dragged and slides a first predetermined distance in the direction of the arrow shown inFIG. 5 , until thefirst pin 633 slides from thefirst protrusion peak 613 to thefirst protrusion valley 611 and thefirst pin 633 is latched by thefirst protrusion 61. In this state, theinner rail 10 and themiddle rail 30 are latched together such that theinner rail 10 can slide together with themiddle rail 30; and thesecond pin 635 slides to the guidingvalley 651 to expand theelastic element 64. - Referring to
FIG. 6 , continuing to drag theinner rail 10, because thefirst pin 633 is latched by thefirst protrusion 61, theinner rail 10, together with themiddle rail 30, slides relative to theouter rail 50. As theinner rail 10 and themiddle rail 30 slide relative to theouter rail 50, thesecond pin 635 slides to thethird protrusion valley 661. - Referring to
FIGS. 7-8 , the inner rail is continued to be pulled and slides together with the middle rail 20 a second predetermined distance until thesecond pin 635 slides to thethird protrusion 66. At this moment, thesecond pin 635 slides from thethird protrusion valley 661 to thethird protrusion peak 663 to drive thesecond pin 635 to slide from the guidinggroove valley 651 toward the guidinggroove peak 652. Thefirst pin 633 can then pass through thefirst protrusion peak 613 making thefirst pin 633 release with thefirst protrusion 61. That is, theinner rail 10 may slide relative to themiddle rail 30 again. Simultaneously, the resistingportion 655 resists the stoppingsurface 664 to prevent themiddle rail 30 from continuing to slide relative to theouter rail 50. Continuing to pull theinner rail 10 makes theinner rail 10 slide relative to themiddle rail 30, thefirst pin 633 slides to thefirst protrusion valley 611 so theinner rail 10 can further extend relative to themiddle rail 30. Thus, theinner rail 10 is extended relative to themiddle rail 30 and theouter rail 50. The movement of pushing theinner rail 10 to its original state is opposite to the movement of extending the rail relative to themiddle rail 30 and theouter rail 50. - It is to be further understood that even though numerous characteristics and advantages of the exemplary embodiments have been set forth in the foregoing description, together with details of structures and functions of various embodiments, the disclosure is illustrative only, and changes may be made in detail, especially in matters of shape, size, and arrangement of parts within the principles of the exemplary invention to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
