2. Description of the Related Art A swing window which is rotated around an end portion of a shoji, a rotating window which is opened and closed by rotating around a fulcrum at an intermediate portion of the shoji, or a fulcrum shaft which slides along a frame is provided. The sliding window which is opened and closed as the center is locked by a locking device so as not to rattle in the fully closed state and the fully opened state, respectively.

[0003]

When these sliding windows, rotating windows, and sliding windows are opened with the sliding doors fully opened, rain easily falls into the room when it rains. In particular, when these windows are used as skylights, since the skylights are installed diagonally on the roof, rain falls from between the shoji and the frame. For this reason, there was a problem that ventilation was not possible in rainy weather.

[0004] In view of the above problems, the present invention has a skylight-opening structure that allows ventilation even when it rains without rain falling into the room, and a skylight that can easily determine the half-open state from the room side. The purpose is to provide.

In order to achieve this object, a skylight of the present invention is provided such that a shoji is rotatably mounted on a frame by using an end or an intermediate portion of the shoji as a fixed fulcrum or a movable fulcrum. Having a structure, a rod attached to a bar on the open end side of the shoji so as to be protruded and retracted with respect to the frame, provided on the frame,
And a locking portion that locks the rod at the protruding position, and the locking means vents through a gap between the frame and the shoji between the fully closed state and the fully opened state of the shoji. A structure having one or more lock positions that can be in a half-open state, a handle for operation is attached to the upper rail of the sash, the handle has a structure linked to the rod, and the handle is ventilable. In a half-open state,
It is characterized by being downward from the fully closed position.

[0006]

The skylight according to the present invention is provided with a mechanism for locking the sash in a semi-open state in which ventilation is possible, that is, in a state where a gap is formed between the airtight material and its contact surface at the airtight material installation portion. Ventilation can be performed in a state where the vehicle does not fall down. The handle is breathable
In a half-open position, it will be lower than the fully closed position.
Thus, the half-open state can be easily determined from the indoor side.

(A), (B) is a perspective view showing the mounting structure of the rod portion and the locking portion constituting the locking means of the sash, respectively. As shown in FIG. 2, the skylight of this example has left and right vertical frames 1, an upper frame 2, and a lower frame 3 made of wood as a main material (a shape material may be used).
Are framed to form a frame 4. The frame 4 is installed in the opening of the roof of the inclined house. The shoji 5 is formed by assembling right and left vertical bars 6, upper bars 7 and lower bars 8 each made of wood as a main material (a shaped material may be used), and a panel 9 (the panel 9 is an outdoor side). (A double panel comprising a panel 9a and an indoor side panel 9b).
The sliding door 5 is configured such that an intermediate portion of the left and right vertical rails 6 is rotatably engaged about a fulcrum 10 at an intermediate portion of the left and right vertical frames 1 to form a rotating window.

As shown in FIGS. 1 to 3, an operating handle 11 and a locking rod 12 interlocking with the handle 11 are attached to the upper rail 7, while the opposing portion of the upper frame 2 is A locking member 15 having a locking portion 13 for fully closing and a locking portion 14 for half-opening in which the rod 12 is fitted is attached.

The mounting structure of the rod 12 will be described with reference to FIGS. 1 and 3 (A). The mounting bracket 17 which houses the rod 12 so as to be able to protrude and retract is fixed to the upper rail 7 by a fixing tool 18 such as a screw. A rotating shaft 20 coupled to the handle 11 via a lever 19 is rotatably penetrated and attached to the mounting bracket 17. A cam 21 is fitted to the rotary shaft 20 in the mounting bracket 17 so as not to rotate, and a pin 22 fixed to the cam 21 is movably fitted to a long hole 12 a provided in the rod 12 in the longitudinal direction. Have been combined. 23
Is a coil spring that biases the rod 12 in a protruding direction.

As shown in FIG. 3A, one end of the handle 11 is connected to the rotating shaft 2 via the lever 19 as described above.
0, and the other end is connected to the distal end of a lever 25. The base end of the lever 25 is rotatably mounted on a shaft 28 attached to a bearing 24 fixed to the upper rail 7 by a fixture 29. Are combined.

On the other hand, as shown in FIG. 1 and FIG.
The locking pieces 26 and 27 made of a metal having high rigidity are accommodated therein, and the locking portions 13 and 14 are respectively formed by these.
In the present example, the depth of the locking portion 14 for bringing into the half-open state is the locking portion 13 for bringing it into the fully closed state (the inner surface of the locking portion 13 is formed by the locking metal 15). It is shallower than that.

Next, the operation of this apparatus will be described. 4 is a vertical cross-sectional view of the upper part of the skylight showing the fully-closed state of the shoji 5, in which the rod 12 is fitted into the upper locking portion 13 by the force of the coil spring 23. Thereby, the rotation of the shoji 5 is prevented. At this time,
The airtight material 30 provided on the inner wall of the upper half of the upper frame 2 and the vertical frame 1 also shown in FIG. 2 abuts against the receiving surface 31 provided on the upper half of the upper bar 7 or the vertical bar 6 and FIG. Although not shown, the airtight material 33 provided on the lower half of the lower frame 3 and the vertical bar 6 shown in FIG.
4 to maintain airtightness. Further, the mohair 35 is in contact with the receiving member 36 to prevent dust and insects from entering.

From this state, a person in the room (not shown)
Holds the operating rod 37 (see FIG. 1), hooks the scratching portion 37a at the tip thereof on the handle 11, and pulls it as shown by the arrow a (the skylight is attached at an angle, as shown in FIG. 1). When the skylight is drawn horizontally, the operation rod 37
Is drawn in a direction inclined as shown by an arrow a) when the operation is performed while holding the vertical
The rotation force indicated by the arrow R in FIG. 1 around the fulcrum 10 (see FIG. 2) in the direction in which the open end of the side, that is, the upper open end of the shoji 5 is drawn into the room, is received. At this time, since the handle 11 is located on the upper frame 2 side with respect to the vertical line passing through the rotation shaft 20, the force for opening the shoji 5 is a force for rotating the handle 11 about the rotation shaft 20 at the same time.
1 and the rotating shaft 20 rotate in the direction indicated by the arrow r. That is, as the cam 21 rotates in the same direction r as the pulling direction a, and the pin 22 comes into contact with the elongated hole 12a of the rod 12, the rod 12 resists the force of the coil spring 23 as shown by a two-dot chain line. When the operation rod 37 is slightly pulled, the rod 12 is pulled out.
When the operating rod 37 is returned upward, the rod 12 is fitted into the lower engaging portion 14 by the force of the coil spring 23, and is locked in the half-open state shown in FIG. . In this half-open state, the receiving surface 31 of the upper half of the upper crosspiece 7 and the upper half of the vertical crosspiece 6 is separated from the airtight material 30 to form a gap between them, and ventilation is possible along the path shown by the dotted line b. The airtight material 33 in the lower half of the lower rail 8 and the vertical rail 6 (see FIG. 2), the lower frame 3 and the receiving surface 3 in the lower half of the vertical frame 1
4, a gap is also formed. In the half-open state shown in FIG. 5, the receiving member 36 of the mohair 35, that is, the shoji 5
The top portion 36a of the edge member (i.e., the outdoor end) covers the lower end 3 of the exterior plate 38 of the frame 4 which covers and faces the receiving member 36.
Since it is located at a higher position (outside of the room) than 8a (that is, the end of the frame 4 facing the receiving member 36 on the indoor side), infiltration of rainwater is prevented in normal rainy weather other than storms. Since the mohair 35 is still in contact with the receiving member 36, the mohair 35 prevents dust and insects from entering.

In this embodiment, the position of the handle 11 is different in each state so that the half-open state in FIG. 5 can be distinguished from the fully closed state. That is, as described above, the depth of the locking portion 14 for making the half-open state is smaller than the depth of the locking portion 13 for making the fully-closed state. Is shorter than in the fully closed state, and a pin 22 integral with the cam 21 is provided.
Is in the protruding state of the rod 12 in contact with one end of the long hole 12a of the rod 12, the handle 11 is turned downward as shown by the solid line d from the fully closed position shown by the two-dot chain line c. The half-open state can be easily identified from the indoor side as a structure for notifying that there is a certain state, so that the half-open state is not left in the half-open state at bedtime or during cooling and heating.

Further, from the state shown in FIG.
When the handle 12 is pulled, the rod 12 comes out of the locking portion 14 by the rotation of the handle 11 as described above, and at the same time,
The shoji 5 is pulled by the pulling force via the operation rod 37.
Is pivoted about the fulcrum 10 so that the upper part of the vehicle is drawn into the room, and the fully open state shown in FIG. 6 is obtained. FIG.
In this state, the sash 5 is locked in the fully open state by a known lock mechanism (not shown). When returning from the fully open state of FIG. 6 to the half open state of FIG. 5 or the fully closed state of FIG. 4, the upper part of the sash is pushed up by the operation rod 37 shown in FIG. The inclined surface 12b is formed on the upper surface of the tip of the rod 12, and the lower end of the latch 15 is formed on the inclined surface 15a. After coming into contact and being slightly pushed in against the force of the coil spring 23, it projects again by the force of the coil spring 23 at the position of the locking portion 14, is fitted into the locking portion 14, and can be returned to a half-open state. When the operating rod 37 is further pushed up, the inclined surface 12b of the rod 12 comes into contact with the upper part of the locking part 14, and the rod 12 is slightly retracted. Locked in state.

In the above embodiment, the unlocking operation, the transition to the half-open state, and the locking and unlocking are performed by using the opening / closing operation means (handle 11) of the shoji 5, so that there is only one operation means. In this case, it is not necessary to newly add an operation means, and the operation is simplified as compared with a case where a plurality of operation means are handled. In addition, locking rod 1
Since one is provided and two locking portions 13 and 14 are provided for this, the fully closed and half-opened locks are reliably performed.

In the present invention, the lock position in the half open state is not limited to one, and a plurality of lock positions having different degrees of opening may be taken. Further, in the present invention, the specific structure and combination of the frame 4, the shoji 5, the handle 11, the rod 12, the locking portions 13, 14 and the like can be variously changed and added in addition to the above embodiment. .

[0018]

According to the present invention , since the skylight is provided with a mechanism which can be locked in the half-open state, the airtight material is set to such an extent as to be separated from the receiving surface through a slight gap in the half-open state. In this way, it is possible to ventilate without rain falling into the room during normal rainy weather. Further, in the half-open state in which the ventilation is possible, the handle is downward from the fully closed position, so that the half-open state can be easily determined from the indoor side. This prevents the device from being left half-open during bedtime or cooling and heating.
