The adjusting apparatus includes a plurality of first engaging members, a driven unit, and a driving unit. The first engaging members are connected to the slats respectively. The driven unit is connected to the frame of the sash for reciprocation, and has a second engaging member, wherein all the first engaging members are engaged with the second engaging member. The driving unit is connected to the carrier and the driven unit respectively to drive the driven unit to move while the sash is being opened. The first engaging members are turned by the second engaging member when the driven unit is moved by the driving unit to turn the slats from the first position to the second position. ## Claims ### Claim 1 An adjusting apparatus for adjusting slats of a sash while the sash is opened, wherein the sash is pivotally connected to a carrier and has a frame, and the slats are pivotally connected to the frame to be turned between a first position and a second position, comprising: a plurality of first engaging members connected to the slats respectively; a driven unit connected to the frame of the sash for reciprocation; the driven unit having a second engaging member; all the first engaging members are engaged with the second engaging member; a driving unit connected to the carrier and the driven unit respectively to drive the driven unit to move while the sash is being opened; wherein the first engaging members are turned by the second engaging member when the driven unit is moved by the driving unit to turn the slats from the first position to the second position; and wherein the driving unit is moved while the sash is being opened to move the driven unit, so that the slats are turned to the second position through the first engaging members and the second engaging member, whereby the slats are turned by opening the sash. ### Claim 2 (depends on 1) The adjusting apparatus of claim 1, wherein the driven unit includes a movable member connected to the second engaging member; the driving unit includes a pushing member and a driving member; the driving member is connected to the frame of the sash and the carrier respectively; the driving member is moved when the sash is being opened, the pushing member is moved by the driving member, and the movable member is moved by the pushing member to generate a relative movement between the second engaging member and the first engaging members to turn the slats. ### Claim 3 (depends on 2) The adjusting apparatus of claim 2, wherein the driving unit further includes a base embedded in the frame of the sash; the base has a cavity, in which the pushing member is received for reciprocation, and the driving member is connected to the base. ### Claim 4 (depends on 3) The adjusting apparatus of claim 3, wherein the driving unit further includes a biasing member which is deposed in the cavity of the base and urges the pushing member in a direction opposite to that of the pushing member being moved by the driving member. ### Claim 5 (depends on 4) The adjusting apparatus of claim 4, wherein the driving member further includes a lateral board and a first roller; the lateral board is connected to the base to cover the cavity, and has an opening communicated with the cavity; the first roller is received in the cavity and pivotally connected to the base; the base has a top board, and the biasing member has opposite ends urging the top board and the pushing member respectively; the driving member has an end fastened to the top board; the driving member runs around the pushing member and the first roller, and then extends out of the base via the opening of the lateral board to be fastened to the carrier. ### Claim 6 (depends on 5) The adjusting apparatus of claim 5, wherein the first roller has a groove, in which the driving member is received. ### Claim 7 (depends on 5) The adjusting apparatus of claim 5, wherein the pushing member has a lid and a second roller pivotally connected to the lid, and the driving member runs around the second roller. ### Claim 8 (depends on 7) The adjusting apparatus of claim 7, wherein the second roller has a groove, in which the driving member is received. ### Claim 9 (depends on 5) The adjusting apparatus of claim 5, wherein the base is provided with a guiding slot; the movable member is provided with a protrusion to be engaged with the guiding slot, and the movable member moves along the guiding slot. ### Claim 10 (depends on 1) The adjusting apparatus of claim 1, wherein the driven unit includes a movable member connected to the second engaging member; the driving unit includes a pushing member and a driving member; the driving member is connected to the pushing member and the carrier respectively; the driving member is moved when the sash is being opened, the pushing member is moved by the driving member, and the movable member is moved by the pushing member to generate a relative movement between the second engaging member and the first engaging members to turn the slats. ### Claim 11 (depends on 10) The adjusting apparatus of claim 10, wherein the driving unit further includes a biasing member which urges the pushing member in a direction opposite to that of the pushing member being moved by the driving member. ### Claim 12 (depends on 1) The adjusting apparatus of claim 1, wherein the driving unit further includes a base, a lateral board, and a first roller; the base is embedded in the frame of the sash; the base has a cavity, in which the pushing member is received for reciprocation; the lateral board is connected to the base to cover the cavity, and has an opening communicated with the cavity; the first roller is received in the cavity and pivotally connected to the base; the driving member runs around the first roller, and then extends out of the base via the opening of the lateral board to be fastened to the carrier. ### Claim 13 (depends on 12) The adjusting apparatus of claim 12, wherein the base is provided with a guiding slot; the movable member is provided with a protrusion to be engaged with the guiding slot, and the movable member moves along the guiding slot.
