Abstract

An apparatus for window is used for moving a movable window plate among an insertion position for being inserted into an aperture portion of a fixed window plate, an extraction position for being extracted from the aperture portion toward an indoor side, and an opening position for being moved from the extraction position in a sliding direction that is different from an inserting and extracting direction to open the aperture portion. The apparatus includes a rotating shaft rotatably supported at a predetermined position for the movable window plate; a movement conversion mechanism configured to convert a rotation of the rotating shaft into a translation of the movable window plate between the insertion position and the extraction position; and a drive shaft, fixed to the rotating shaft, configured to rotate the rotating shaft around a central axis of the rotating shaft by revolving around the central axis of the rotating shaft.

First claim

What is claimed is:

1. An apparatus for moving a movable window plate, comprising:
a rotating shaft rotatably supported at a predetermined position for a movable window plate;
a movement conversion mechanism comprising a cam fixed to the rotating shaft and having an extension shaft of the rotating shaft, and a fixture guide fixed to a fixed window plate and including a cam guide groove for guiding the cam in contact with an outer periphery of the cam on a wall surface of the cam guide groove on an indoor side direction of the fixed window plate and a shaft guide groove for guiding the extension shaft of the rotating shaft on a groove bottom surface of the cam guide groove such that the movement conversion mechanism is configured to convert a rotation of the rotating shaft into a translation of the movable window plate between an insertion position for being inserted into an aperture portion of the fixed window plate and an extraction position for being extracted from the aperture portion toward the indoor side direction of the fixed window plate;
a drive shaft fixed to the rotating shaft and configured to rotate the rotating shaft around a central axis of the rotating shaft by revolving around the central axis of the rotating shaft; and
an elastic member configured to press the extension shaft of the rotating shaft against a wall surface of the shaft guide groove on an outdoor side direction of the fixed window plate, and press the cam against the wall surface of the cam guide groove on the indoor side direction of the fixed window plate, while the movable window plate is slid between the extraction position and an opening position for being moved from the extraction position in a sliding direction that is different from an inserting and extracting direction to open an aperture portion of the fixed window plate,
wherein the wall surface of the cam guide groove on the indoor side direction of the fixed window plate is parallel to a main surface of the fixed window plate, a distance between the wall surface of the cam guide grove on the indoor side direction of the fixed window plate and the central axis of the rotating shaft varies in response to a rotational angle of the rotating shaft, the cam has a fitting convex portion on the outer periphery, and the fixture guide has a fitting concave portion on the wall surface of the cam guide groove on the indoor side direction of the fixed window plate, and in a middle while the movable window plate is slid between the extraction position and the opening position, the fitting convex portion is fitted into the fitting concave portion by an elastic restoring force of the elastic member.

2. The apparatus for window according to claim 1 , wherein when the movable window plate is located at the insertion position, the wall surface of the cam guide groove on the indoor side direction is in contact with the outer periphery of the cam on both sides of a reference line perpendicular to the main surface of the fixed window plate and through the central axis of the rotating shaft.

3. The apparatus for window according to claim 2 , wherein the fixture guide has a convex portion on a wall surface of the cam guide groove on the outdoor side direction of the fixed window plate such that the convex portion is in contact with the outer periphery of the cam between the insertion position and the extraction position of the movable window plate, and the cam is configured to change a direction by climbing over the convex portion.

4. The apparatus for window according to claim 3 , wherein the cam has an eccentric shaft eccentric to the extension shaft and having a shaft diameter of less than a shaft diameter of the extension shaft such that the eccentric shaft and the extension shaft are inserted into the shaft guide groove.

5. The apparatus for window according to claim 4 , wherein the movable window plate moves from the insertion position to the extraction position through a protrusion position on an outdoor side of the insertion position by the rotation of the rotating shaft in a predetermined direction.

6. The apparatus for window according to claim 3 , wherein the movable window plate moves from the insertion position to the extraction position through a protrusion position on an outdoor side of the insertion position by the rotation of the rotating shaft in a predetermined direction.

7. The apparatus for window according to claim 2 , wherein the cam has an eccentric shaft eccentric to the extension shaft and having a shaft diameter of less than a shaft diameter of the extension shaft such that the eccentric shaft and the extension shaft are inserted into the shaft guide groove.

8. The apparatus for window according to claim 2 , wherein the movable window plate moves from the insertion position to the extraction position through a protrusion position on an outdoor side of the insertion position by the rotation of the rotating shaft in a predetermined direction.

9. The apparatus for window according to claim 1 , wherein the fixture guide has a convex portion on a wall surface of the cam guide groove on the outdoor side direction of the fixed window plate such that the convex portion is in contact with the outer periphery of the cam between the insertion position and the extraction position of the movable window plate, and the cam is configured to change a direction by climbing over the convex portion.

10. The apparatus for window according to claim 9 , wherein the cam has an eccentric shaft eccentric to the extension shaft and having a shaft diameter of less than a shaft diameter of the extension shaft such that the eccentric shaft and the extension shaft are inserted into the shaft guide groove.

11. The apparatus for window according to claim 9 , wherein the movable window plate moves from the insertion position to the extraction position through a protrusion position on an outdoor side of the insertion position by the rotation of the rotating shaft in a predetermined direction.

12. The apparatus for window according to claim 1 , wherein the cam has an eccentric shaft eccentric to the extension shaft and having a shaft diameter of less than a shaft diameter of the extension shaft such that the eccentric shaft and the extension shaft are inserted into the shaft guide groove.

13. The apparatus for window according to claim 12 , wherein the movable window plate moves from the insertion position to the extraction position through a protrusion position on an outdoor side of the insertion position by the rotation of the rotating shaft in a predetermined direction.

14. The apparatus for window according to claim 1 , wherein the movable window plate moves from the insertion position to the extraction position through a protrusion position on an outdoor side of the insertion position by the rotation of the rotating shaft in a predetermined direction.
