Apparatus for window

1. An apparatus for a window used for moving a sliding window plate between

an insertion position, at which the sliding window plate is inserted into an opening portion of a fixed window plate,

an extraction position, at which the sliding window plate is extracted from the opening portion, and

an open position, at which the sliding window plate is shifted in a slide direction that is different from an extraction/insertion direction from the extraction position, and the sliding window plate uncovers the opening portion,

the apparatus for a window comprising:

a rotary member that is rotatably supported on a sliding base with respect to the sliding window plate;

a drive member that is moved in a predetermined direction that is different from the extraction/insertion direction with respect to the sliding window plate according to a rotation force of the rotary member;

a fixation guide configured to convert a movement of the drive member in the predetermined direction with respect to the sliding window plate into a movement of the sliding window plate in the extraction/insertion direction with respect to the fixed window plate,

wherein the fixation guide has a slide groove configured to guide the drive member in the slide direction,

wherein the slide groove has a recess portion configured to temporarily stop the sliding window plate at an intermediate position between the extraction position and the open position; and

a wire configured to pull the drive member in the predetermined direction according to the rotation force of the rotary member, and move the drive member in the predetermined direction,

wherein the drive member includes

a pin having a tip portion in contact with the fixation guide,

a block to be coupled to the wire, and

a spring configured to apply force to the pin in a direction away from the block, and

wherein the spring presses the pin against the recess portion according to an elastic restoring force of the spring.

2. The apparatus for a window according to claim 1 ,

wherein the wire comprises two end portions that are fixed to an outer periphery of the rotary member,

wherein, as the rotary member rotates, a first portion of the wire is wound up onto the outer periphery of the rotary member, and at the same time, a second portion of the wire is unwound from the outer periphery of the rotary member.

3. The apparatus for a window according to claim 2 ,

wherein a total amount of winding of the first portion of the wire and a total amount of unwinding of the second portion of the wire, while the sliding window plate moves from one of the insertion position and the extraction position to an other of the insertion position and the extraction position, are the same.

4. The apparatus for a window according to claim 2 ,

wherein a speed of the first portion of the wire being wound up by the rotary member and a speed of the second portion of the wire being unwound from the rotary member, while the sliding window plate moves from one of the insertion position and the extraction position to an other of the insertion position and the extraction position, are the same.

5. The apparatus for a window according to claim 2 ,

wherein the wire includes a plurality of wires, and

wherein the plurality of wires wind around the outer periphery of the rotary member symmetrically.

6. The apparatus for a window according to claim 2 ,

wherein the outer periphery of the rotary member has a cross section with a shape of a circle.

7. The apparatus for a window according to claim 1 ,

wherein the predetermined direction is different from the extraction/insertion direction and the slide direction.

8. The apparatus for a window according to claim 1 further comprising

the sliding base to which the sliding window plate is fixed,

wherein the rotary member and the drive member are arranged on the sliding base.

9. The apparatus for a window according to claim 1 , further comprising the sliding base supporting the sliding window plate and rotatably supporting the rotary member,

wherein the fixation guide comprises a lock groove that the drive member is at least partially positioned within in the insertion position, wherein the lock groove prevents movement of the sliding window plate in the slide direction and in the extraction/insertion direction.
