U.S. Patent No. 5,040,833 to Brunnert discloses a "Closing Device For Drawers", which includes a drawer installed to a furniture body. The drawer is movable between a closed position and an open position, as shown inFigs. 2-6 ,18a and 18b ofU.S. Patent No. 5,040,833 . A spring is located between the drawer and the furniture body. A holding member is fixed to the furniture body and has a front end. A latch member is fixed to the drawer and includes a first raised area and a second raised area, wherein the second raised area includes a notch which is located corresponding to the first raised area. The second raised area further includes an inclined guide track. When the drawer is located at the closed position relative to the furniture body, the front end of the holding member is guided by the inclined guide track of the second raised area to be engaged with the notch of the second raised area. When the drawer applies a force relative to the furniture body, the front end of the holding member is guided by the guide track of the first raised area to be engaged with another guide track and is disengaged from the notch. The drawer is pushed by the force of the spring and moved to a self-opening position relative to the furniture body. - The front end of the holding member is in a free status when the drawer is opened relative to the furniture body and the holding member is disengaged from the latch member. In this status, when the drawer is pushed to its closed position, the drawer can only travel through the same processes to let the front end of the holding member engage with the notch of the latch member.
- However, if the demand is that the holding member and the latch member do not have a locked relationship when the drawer is located at the close status, especially when the drawer has a self-closing function. The relationship between the holding member and the latch member has to be changed. The present invention provides an improved structure to include the functions which the conventional closing device does not have.
- The present invention relates to a slide assembly with an auxiliary positioning device and comprises a first slide member and a second slide member which is longitudinally and slidably movable relative to the first slide member. The second slide member has a stored opening force relative to the first slide member when in a closed position. The auxiliary positioning device comprises a positioning member, a guiding base and a link member. The positioning member is pivotally connected to the first slide member and includes a pin member. The guiding base is attached to the second slide member and comprises a first passage, a first slot and a first wall, wherein the first wall has a first guide surface facing the first passage. The guiding base further comprises a second passage, a second slot and a second wall, wherein the second wall has a second guide surface facing the second passage. The guiding base further comprises a separation body having a guiding end which faces the first slot. The guiding base further comprises an engaging body having an engaging surface which has a portion facing the second slot. The guiding base further comprises a third passage, a third slot and a third wall, wherein the third wall has a third guide surface facing the rest portion of the engaging surface. The guiding base further comprises a fourth wall having a fourth guide surface. The link member is located corresponding to the positioning member.
- When the second slide member is in a closed position relative to the first slide member, the pin member is located in a first path in the first passage of the guiding base.
- When the second slide member applies a force relative to the first slide member, the pin member is guided by the first guide surface of the first wall and moves from the first path to the first slot. The pin member is located at a first position.
- When the force is released, the pin member is guided by the guiding end of the separation body and moves from the first position to a second path in the second passage.
- When the second slide member is retracted relative to the first slide member, the pin member is guided by the second guide surface of the second wall and moves from the second path to the second slot via the second passage. The pin member is located in a second position. When the second slide member is released, the pin member moves away from the second position and is engaged with the engaging surface of the engaging body and located in a third position.
- When the second slide member further applies a force relative to the first slide member again, the pin member is guided by the third guide surface of the third wall and moves from the third position into the third slot. The pin member is located in a fourth position. When the second slide member is released, the pin member is guided by the fourth guide surface of the fourth wall.
- When the second slide member moves relative to the first slide member, the link member pivots the positioning member by the movement of the second slide member.
- The primary object of the present invention is to provide an auxiliary positioning device for a slide assembly to control the slide assembly to be positioned by operation of the auxiliary positioning device when the slide assembly is to be closed, such that the slide assembly is easily operated whenever it is closed or opened.
