Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rail structure of a window frame capable of operating a cross door with a single left and right moving guide groove. 2. Description of the Related Art As a rail structure of a window frame capable of operating a crossing door with a single left and right moving guide groove, the applicant has proposed a rail structure of a window frame in Japanese Patent Application No. 11-174197 (see FIG. 3). )
It is disclosed in. In the rail structure of this window frame, a left and right moving guide groove 32 and lead-in grooves 34a and 34b for accommodating a door 33 are provided on both wings of the left and right moving guide groove 32, and a pillar 35 having a trapezoidal cross section is provided at the center. It was done. In the above-described rail structure of the window frame, when the door 33 is housed in the window frame 31, the rollers 36 provided above and below the door 33 are rolled into the drawing grooves 34a and 34b, and the door 33 is set in a crossing state. When opening one side, push the door 33 obliquely forward and push the roller 3
6 is drawn from the grooves 34a and 34b into the left and right movement guide grooves 32.
And move left or right. In the above-mentioned conventional rail structure of a window frame, in order to open the door with one side of the door crossing, the door is pushed obliquely forward and rollers provided on the door are moved left and right. It must be moved to the left or right after being located in the guide groove, and when housing the door, the door must be moved to the edge of the window frame, and then the operation to pull it diagonally toward you must be done Very cumbersome. In view of the above situation, according to the present invention, the operation of pushing the door obliquely forward (or the operation of pulling it obliquely toward the front) and the operation of moving it to the left and right are performed automatically and continuously only by applying a lateral force to the door. An object of the present invention is to provide a rail structure of a window frame that can be smoothly performed. In order to solve the above problem, the present invention provides a left and right moving guide groove 2 on a lower upper surface and an upper lower surface of a window frame 1 ,
Two pull-in grooves 4a, 4b, 4 each extending diagonally outward from both end portions thereof , and then in parallel with the left and right movement guide grooves 2.
a ', 4b' are extended, and an inclined protrusion 7a is provided on the upper surface of the outer wall of the drawing groove 4a.
A part of the upper wall was cut out parallel to the left and right movement guide groove 2.
(Notch 9) inclined projection 7b provided, and the horizontal movement guide grooves 2 on the upper and lower surfaces of the door 3 pull grooves 4a, 4b, 4a ',
4b ' are provided with rollers 6a and 6b.
a, 6b, between the drawing grooves 4a , 4b, 4a ',
Guide pieces 8a and 8b are provided at the same inclination angle as 4b '.
The guide piece 8a corresponds to the inclined protrusion 7a.
The guide piece 8a is inclined in the same direction as the recessed groove 4a.
Slant in the same direction as the recessed groove 4a 'corresponding to the oblique projection 7b
Then, the notch of the inclined protrusion 7b is used when the door 3 moves.
When the door 3 moves to the left, it becomes a passage for the guide piece 8a.
When the guide piece 8a hits the inclined protrusion 7a and the arrow Ya
The door 3 is drawn in with the rollers 6a and 6b by the torque component.
4a, 4b, when the door 3 moves to the right, an arrow Yb
Door 3 with rollers 6a, 6b
It returns to the movement guide groove 2 and moves to the right, and the guide piece 8a is notched.
9, the guiding piece 8b hits the inclined projection 7b,
The door 3 together with the rollers 6a and 6b is driven by the vector component Yc.
Guided by the recesses 4a ', 4b'
It is. According to the present invention configured as described above, the operation of pushing the door obliquely forward (or the operation of pulling it obliquely toward the front) and the operation of moving it to the left and right can be performed automatically only by applying a lateral force to the door. It can be performed smoothly continuously. Next, an embodiment according to the present invention will be described with reference to FIGS. 1 and 2. FIG. A left and right movement guide groove 2 is provided below the window frame 1, and two lead-in grooves 4 a, 4 b, 4 a ′, 4 b ′ extend diagonally outward at both ends thereof.
Its end is parallel to the left-right movement guide groove 2. An inclined projection 7a is provided on the upper surface of the outer wall of the drawing groove 4a, and an inclined projection 7 partially cut away in parallel with the left and right movement guide groove 2 is provided on the upper surface of the outer wall of the drawing groove 4a '.
b is provided. On the lower surface of the door 3, there are provided rollers 6a and 6b which fit into the above-mentioned left and right movement guide groove 2 and the drawing groove 4 (4a, 4b, 4a 'and 4b' as a whole).
The guide pieces 8a and 8b are provided between the guide grooves 6b at the same inclination angle as that of the drawing groove 4. The guide piece 8a corresponds to the inclined protrusion 7a and is inclined in the same direction as the drawing groove 4a.
Corresponds to the inclined protrusion 7b and is inclined in the same direction as the drawing groove 4a '. The notch 9 of the inclined projection 7b serves as a passage for the guide piece 8a when the door 3 moves, and when the door 3 moves to the left, the guide piece 8a hits the inclined projection 7a and the arrow Ya is caused by the vector component. The force acts in the direction shown in FIG. 1 (b), and the rollers 6a, 6b are guided by the drawing grooves 4a, 4b, so that the door 3 is accommodated in the window frame 1. In addition, the inclined protrusion 7
In a, when the door 3 moves to the left by slightly retreating from the lateral movement guide groove 2, the guide piece 8b does not collide. Conversely, when the door 3 is moved rightward from the above state, first, as shown by the arrow Yb, the roller 6 is moved along the drawing groove.
a and 6b move diagonally forward, move rightward along the left-right movement guide groove 2, the leading guide piece 8a passes through the notch 9, and the succeeding guide piece 8b hits the inclined protrusion 7b, and the vector component The force acts in the direction of the arrow Yc by the force, and the rollers 6a and 6b are guided by the drawing grooves 4a 'and 4b', and the door is housed in the window frame. In the above description, one door has been described. However, two doors are usually fitted, and both doors are closed when both doors are accommodated in the window frame. Moving in front of the other door opens one window. Further, the rail structure has been described only for the lower side of the window frame. However, in the case of a door having a low height, only the lower side is sufficient, and in the case of a high door, a similar rail is provided on the upper side of the window frame. Provide for smooth movement. The roller can be replaced with a cylindrical body, and a roller can be provided at the tip of the cylindrical body, or a sphere can be rotatably fitted into the cylindrical body. Anything that moves smoothly can be used, and these are collectively referred to as copying pieces. The material can be appropriately selected from engineering plastics, steel for machine structural use, stainless steel, brass and the like. As described above, according to the present invention,
By simply applying a force in the left and right direction, the operation of pushing the door diagonally forward or pulling it obliquely toward the front and the operation of moving it to the left and right can be performed automatically and continuously smoothly, making it easier to open and close the door.
