Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a hinge device for an inward-folding window, which opens the window while tilting the window sash toward the indoor side, and particularly relates to a hinge device for an inward-tiling window that allows the window sash to be pivoted rotatably relative to the window frame. The present invention relates to a hinge device having a function of holding the window sash in an open state as well as a function of supporting the window sash.

With this type of conventional hinge device, the window shoji could only be opened to an upward position on the indoor side, or at most to a horizontal position, which meant that the room could not be sufficiently ventilated, or the window could not be opened vertically. If the window is set up in two tiers, the lower tier is the corps, and the upper tier is a window that folds inward, and a protective shelf is installed on the outside of the window, it may not be possible to wipe the outside of the window glass, especially the lower tier. There was an inconvenience.

In view of the above, the present invention solves the conventional inconveniences by configuring the window shoji to be rotated substantially 180 degrees from its closed position toward the indoor side, and also makes the configuration simple and extremely easy to operate. An embodiment of the present invention will be described below in detail with reference to the drawings.

FIG. 1 is an assembled state diagram of a hinge device A according to the present invention, and FIG.
The figure shows a perspective view of the exploded state. In the figure, 1 is a fixed hinge plate. On one side of the fixed hinge plate 1, the end surface 3 of the indoor side edge is inclined outward (slanted towards the outdoor). The movable hinge plate 2 formed in the movable hinge plate 2 (which is defined as the meaning of the expression) is made to face each other, and a first shaft 6 is provided between the mouse hole 5 provided at one end of the movable hinge plate 2 and the koji hole 4 provided at one end of the fixed hinge plate 1. The movable hinge plate 2 is rotatably pivoted to the fixed hinge plate, and the stopper plate 7 is provided in the center of the fixed hinge plate, with the stopper plate 7 facing the other side of the fixed hinge plate. A long hole 9 extending from the outer lower end of the stopper plate 7 to the center thereof in an inwardly inclined shape (meaning that it is inclined toward the interior).
The second shaft 10 is inserted through the stopper plate 7.
The stopper plate 7 is rotatably attached to the fixed plate and is slidable diagonally inward and upward and downward, and the movable hinge plate 2 is attached to the inner twill upper end of the stopper plate 7 when the movable hinge plate 2 rotates inward. A stopper piece 11 supporting the inclined end surface 3 of the plate 2 extends at right angles, and a lower end surface 12 of the indoor side edge of the stopper plate 7 is formed to be inclined inward. The end of the above-mentioned fixed hinge plate, that is, the outdoor end forms a mounting part 13, and this mounting part 13 is connected to the main body of the hinge plate 1 near the stopper plate 7 via a bent step 14. One part is slightly protruding.

Further, the outdoor end of the movable hinge plate 2 is bent and extended in an L-shape in a direction opposite to the direction in which it faces the fixed hinge plate to form a mounting portion 15. For example, a rivet may be used as the first shaft 6, and after inserting it into the vehicle access holes 5, 4, the tip of the rivet may be caulked in a state in which the movable hinge plate 2 can rotate. Note that a slider 16 is inserted between the shaft holes 5 and 4 in the first shaft 6. For example, a bolt with a threaded tip may be used as the second shaft 10, and after being inserted into the bag hole 8 and the long six 9, the nut 17 may be screwed. Note that the elongated hole 9 of the stopper plate 7 has a second bag scale hole ga formed at its upper end, and the stopper plate 7
When in the lowered position as shown in the figure (second axis 1
0 is located at the upper end of the elongated hole 9), the stopper plate 7 is prevented from sliding easily. An example of the use of the hinge device A having the above-mentioned configuration will be described with respect to a window as shown in FIG. 3. The window illustrated in FIG.
The upper window is an inward-folding window, and the lower window shoji C is fixedly attached to the lower part of the window outer frame ○, that is, cannot be opened or closed.The upper window shoji B is attached to the upper part of the window outer frame D by the hinge. device A,
It is attached to the indoor side via A so that it can rotate inward.

When installing each hinge device A, as shown in FIGS. 4 to 7, the mounting portion 15 of the movable hinge plate 2 is
Insert a screw 2 into the lower front side of the vertical shaft 18 that makes up the window shoji B.
At the same time, the mounting portion 13 of the fixed hinge plate is mounted and fixed with screws 22 on the inner surface of the vertical shaft 21 constituting the window outer frame D, and the stopper plate 7 is fixed.
The outdoor upright end surface 7a of is the middle part 23 that constitutes the outer frame D.
The front side surface 24a of the draining portion 24 can be latched to the front surface 24a. FIG. 4 shows the window closed state in which the window shoji B is completely housed within the window frame D. In this state, the stopper plate 7 is pulled down and the upper end of the nearest hole 9 in the plate 7 The opening 9a) is hooked to the second shaft 10, and when the window shoji B is rotated inward (toward the room) from this closed state, the movable hinge plate 2 integrated with the shoji B is tilted. The end surface 3 comes into contact with the stopper piece 11 of the stopper plate 7, thereby holding the window shoji B in a tilted state as shown in FIG. Upright end face 7
a is fixed to the front side surface 24a of the draining portion 24, so that the stopper plate hole is maintained in an upright state.
Next, when the stopper plate 7 is pulled up along the inclination direction of the elongated hole 9 from the state shown in FIG. The movable hinge plate 2 is released from the stopper plate 7 and becomes rotatable. Therefore, the stopper plate 7 is
At the lower end of the elongated hole 9, the plate 7 is turned inward about the second shaft 10 so that the inclined end surface 12 of the plate 7 on the indoor side is brought into contact with the front side surface 24a of the draining part 24, and the plate 7 is turned on the indoor side. The window shoji B
is rotated further inward from the state shown in FIG. 5 and reversed 1800 degrees from the closed position shown in FIG. 4 as shown in FIG. The window sash B is supported by the stopper piece 11, and the window shoji B is held in an inverted state. In FIG. 3, 25 is a well-known locking device for holding and fixing the window sash B in the closed position, and is interposed between the horizontal frame 19 of the window sash B and the upper frame 26 of the window outer frame D. ing.

As described above, according to the present invention, the movable hinge plate 2 attached to the window sash is rotatably attached to the fixed hinge plate 1 attached to the window outer frame by the first shaft 6, and the fixed hinge plate 1 is attached to the fixed hinge plate 1 attached to the window outer frame. the stopper plate 7 to the second shaft 1
0, and the indoor side edge of the movable hinge plate 2 is formed into an inclined end surface 3, and the movable hinge plate 2 is attached to the stopper plate 7 so as to move toward the indoor side at a required angle around the first axis 6. Since a stopper piece 12 is protrudingly provided to prevent further movement of the forehead when the inclined end face 3 abuts against the brush, the window shoji can be kept tilted toward the indoor side and the room can be ventilated freely.

In particular, in the present invention, the stopper plate 7 is provided with a long hole 9 that is slightly inclined toward the indoor side from the lower end to the upper end, and the second shaft 10 is inserted through the long hole 9 to attach the stopper plate 7 to the fixed hinge plate. It can be rotated freely against
The stopper plate 7 is pivotally mounted so that it can be slid vertically while deflecting indoors and outdoors along the elongated hole 9, and the edge of the stopper plate 7 touches the window frame to keep the stopper plate 7 upright or indoors. Since an upright surface 7a on the outdoor side and an inclined end surface 12 on the indoor side are formed on the edge of the stopper plate to keep the stopper plate in a tilted state, the stopper plate can be slid upward and tilted toward the indoor side. By simply rotating the window sash, it is possible to turn the window sash from its upright (closed) state approximately 1,800 degrees along the indoor wall surface, which allows for more adequate ventilation in the room, as well as It is possible to easily clean the outdoor surface on the indoor side.

In particular, when a window has two levels (upper and lower), the lower level is a troop window, and the upper level is a window that folds inward, and a lattice-shaped protective shelf is installed on the outside of the window, the conventional hinge device cannot handle the window. However, according to the present invention, the window shoji that folds inward can be turned over to the indoor wall surface, so cleaning not only the upper window glass but also the outer surface of the lower window glass can be done easily. This can be easily done by inverting the shoji and keeping it in the folded state.
