Abstract
An opening device for a slide assembly includes a swing member with a pin portion, a first resilient member and a pusher connected to the first rail. The first resilient member applies a force to the pusher. An engaging member pivotably connected to the second rail and includes a block and a positioning leg contacting a portion of the second rail. The engaging member is connected to a second resilient member. When the second rail is retracted relative to the first rail, the block of the engaging member contacts the pin portion of the swing member. When a pull force is applied to the retracted second rail, the engaging member swings an angle on the second rail to disengage the block from the pin portion of the swing member, and the engaging member returns to its original position relative to the second rail.
Claims (9)
1. An opening device for a slide assembly, comprising:
a first rail;
a second rail which is movable in longitudinal direction relative to the first rail;
a stationary member fixed to the first rail and comprising a first end and a second end which is located opposite to the first end, a longitudinal portion located between the first and second ends;
a swing member pivotably connected to the second end of the stationary member and comprising a pin portion;
a pusher longitudinally connected to the longitudinal portion of the stationary member;
a first resilient member connected to the pusher;
an engaging member pivotably connected to the second rail and comprising a first end and a second end which is located opposite to the first end, a first wall, a second wall, a third wall, a connection wall, a block and a positioning leg located between the first and second ends, the connection wall extending from the first end and connected to the first wall, the second wall and the third wall, the first wall and the block defining a first path, the block and the third wall defining a second path, the block having an engaging surface and a guide portion defined in two ends thereof, the first wall, the second wall and the connection wall defining a first slot, the second wall, the third wall and the connection wall defining a second slot which faces the second path, the first wall comprising a first guide surface facing a portion of the first path, the first path located corresponding to a portion of the first slot, the second wall comprising a second guide surface facing the engaging surface of the block, the engaging surface having an inclined surface extending therefrom which faces a portion of the first slot, the third wall comprising a third guide surface, the positioning leg extending from the second end of the engaging member and contacting a portion of the second rail, a second resilient member connected between the first end of the engaging member and the second rail, and when the second rail is retracted relative to the first rail, the engaging surface of the block of the engaging member is engaged with the pin portion of the swing member, when the second rail is pulled out relative to the first rail, the engaging member overcomes a force between the second resilient member and the positioning member, and swings an angle on the second rail, the engaging surface of the block of the engaging member is disengaged from the pin portion of the swing member, the positioning leg and the second resilient member return the engaging member relative to the second rail.
a first rail;
a second rail which is movable in longitudinal direction relative to the first rail;
a stationary member fixed to the first rail and comprising a first end and a second end which is located opposite to the first end, a longitudinal portion located between the first and second ends;
a swing member pivotably connected to the second end of the stationary member and comprising a pin portion;
a pusher longitudinally connected to the longitudinal portion of the stationary member;
a first resilient member connected to the pusher;
an engaging member pivotably connected to the second rail and comprising a first end and a second end which is located opposite to the first end, a first wall, a second wall, a third wall, a connection wall, a block and a positioning leg located between the first and second ends, the connection wall extending from the first end and connected to the first wall, the second wall and the third wall, the first wall and the block defining a first path, the block and the third wall defining a second path, the block having an engaging surface and a guide portion defined in two ends thereof, the first wall, the second wall and the connection wall defining a first slot, the second wall, the third wall and the connection wall defining a second slot which faces the second path, the first wall comprising a first guide surface facing a portion of the first path, the first path located corresponding to a portion of the first slot, the second wall comprising a second guide surface facing the engaging surface of the block, the engaging surface having an inclined surface extending therefrom which faces a portion of the first slot, the third wall comprising a third guide surface, the positioning leg extending from the second end of the engaging member and contacting a portion of the second rail, a second resilient member connected between the first end of the engaging member and the second rail, and when the second rail is retracted relative to the first rail, the engaging surface of the block of the engaging member is engaged with the pin portion of the swing member, when the second rail is pulled out relative to the first rail, the engaging member overcomes a force between the second resilient member and the positioning member, and swings an angle on the second rail, the engaging surface of the block of the engaging member is disengaged from the pin portion of the swing member, the positioning leg and the second resilient member return the engaging member relative to the second rail.
2. The device as claimed in claim 1, further comprising a third rail which is longitudinally slidable between the first and second rails.
3. The device as claimed in claim 1, wherein the longitudinal portion includes a groove in the stationary member so as to form a rail body, the longitudinal portion includes a recessed installation portion and the pusher includes a guide slot with which the rail body is engaged.
4. The device as claimed in claim 1, wherein the second end of the stationary member has a base portion extending therefrom which includes a hole and the swing member has a shaft which is pivotably connected to the hole.
5. The device as claimed in claim 1, wherein the second end of the stationary member has a restriction portion extending therefrom which includes a restriction slot and the swing member has a tongue which is inserted into the restriction slot.
6. The device as claimed in claim 1, wherein the swing member has a reinforcement member extends through the pin portion.
7. The device as claimed in claim 1, wherein a connection member is connected to the stationary member and includes a link and a head which is fixed to an end of the link, the first resilient member is mounted to the link and the pusher includes an aperture through which the link extends so that the pusher is biased by the first resilient member.
8. The device as claimed in claim 1, wherein the engaging member includes first contact portion and the second rail includes a second contact portion which is located corresponding to the first contact portion, the first contact portion contacts a portion of the second contact portion.
9. The device as claimed in claim 1, wherein the second rail includes a second contact portion which includes a protrusion and the positioning leg contacts the protrusion.
