Description

[Detailed description of the invention] 〔Technical field〕 This invention relates to a skylight opening/closing structure.

[Background technology]

As a conventional example, Japanese Patent Publication No. 57-071979 f'[l
There is a skylight (Patent Application No. 5e-128858). This skylight has a rotation axis extending parallel to the second cross beam on the ridge side of the upper cross beam of the opening frame installed on the Eve 1 slanted roof, and the base end of the window can be rotated around the rotation axis. The tension coil springs can be removed along the two crossbeams of the open L frame, and the lower part of the operating levers placed on both sides of the springs can be pivotally connected to the L crossbeams for operation. Connect the center part of the lever to both ends of the tension spring, and install guides extending parallel to the two-part crossbeam on both sides of the base 6111 of the lower surface of the window, as well as the guides F.
A mechanical screw I/N is movably mounted inside the piston, and the top end of the working bar is connected to the sliding piston. In this way, by utilizing the tensile force of the tension coil spring, the window is opened by rotating and raising the operating lever so that the sliding piston slides inward of the shaft 1-.

However, since the rotational direction of the window and the rotational direction of the operating lever are orthogonal to each other, the frictional resistance between the Chi 1 and 111 moving pistons increases, resulting in the problem that the window cannot be opened and closed smoothly. Ta. In addition, the window is held open by hooking the locking pawl into the groove of the locking element provided on the window side, so if the window is closed while it is still hooked, the locking element and There was also a risk that her nails would break. In addition, since the angle at which the window is opened and held is determined by the position of the concave groove of the locking element, the window can be opened in stages as many as the number of concave holes. It also had the disadvantage of not being able to maintain its opening.

[Purpose of the invention]

The purpose of this invention is to allow the window to open and close smoothly.
To provide a skylight opening/closing structure that increases durability and allows the window to be opened and held at any angle.

(Disclosure of the Invention) The large window opening/closing structure of the present invention comprises: an opening frame; a pair of vertical pieces protruding from one side of the opening frame and facing each other;
A horizontal rotating shaft is hung between the tips of both vertical pieces, and a pair of sliding shaft guides are formed facing each other so as to extend in a radial direction with respect to the rotating shaft at the proximal end of both mold surfaces (L). 1) A sliding shaft slidably hung between these guide parts, one end of which is pivotally connected to the rotating shaft; A cam formed with a gradually increasing cam surface, and C1 between the sliding shaft and the rotating shaft.
It is equipped with two suspended sliding shafts that are in contact with the cam surface and a tension spring, and a window frame whose base end is fixed to the -V section of the cam.

An embodiment of the present invention will be described with reference to FIGS. 1 to 8. Fig. 1 is a perspective view showing the window closed, and Fig. 2 shows the window open. 3 is an enlarged cross-sectional view of the window in the closed state, FIG. 4 is a side view of the main part thereof, and FIG. 5 is an enlarged 11ji-ji diagram of the window in the open state.

In these figures, 1 is a metal split L frame, which is fixed to a wooden frame 2 (Fig. 3) installed on the roof with hinges 3. 4 is a metal window frame, into which a glass plate 5 is fitted. As shown in FIG. 122, this window frame 4 can be opened upwards from a pair of connecting mechanisms A (one of which is not shown) arranged on both sides of the frame 1, and can be opened upwardly by a side force.・
Squid takes it to 4 (=J gets it).

Figure 6 shows 'J3!' to the above connection mechanism. :ITH2'l view is deleted.

In the figure, 6 is a case having a pair of vertical pieces 6a facing each other, and a horizontal rotation shaft 7 is not extended between one end of both vertical pieces 6a. Reference numeral 8 denotes a cam having an inverted U-shaped cross section, consisting of an upper piece 8a and both side pieces 8b.One end side of both sides of the cam 8a is pivoted to the rotating shaft 7, and a cover 8c is attached to the other end side. ). In addition, the outer circumferential curved surface on the other end side of the cam 8 is finished into a cam surface 9 whose radius of curvature relative to the rotating shaft 7 gradually increases from the F part toward the top, and the rotating shaft 7 is set as the center of curvature at the center of both sides M' 8 b. Arc-shaped guide holes II) are formed opposite to each other. Then, the angle JU control shaft 11 is connected to both the guide holes 1o.
The angle regulating shaft 11 regulates the rotation angle of the cam 8 by bridging between both the vertical pieces 63 in a state where the rotation shaft 71:''-11 is fixed.This regulating angle is normally
: Set so that the base does not open more than 45 degrees, but you are of course free to set the angle other than 45 degrees.

On one side, on the other side of both vertical pieces 6a, there is a letter IL attached to the rotating shaft 7.
, sliding shaft guide elongated holes 12 are formed facing each other so as to extend in the radial direction, and the sliding shaft 13 is freely slidable between these kite elongated holes 12 (as well as the sliding shaft 13 and the above-mentioned A tension coil spring 14 is suspended between the rotating shafts 7, and the sliding shaft 13 is brought into pressure contact with the cam surface 9.The only feature of this connection mechanism is the mounting portion 6b of the case 6.

6C is fixed to both sides of the opening frame l (Figs. 1 and 2) with hisses 15 (Fig. 4).

A kite rail 16 is fixed to the upper piece 8a of the cam 8 with a screw 17 as shown in FIG. , The upper frame 4 can be attached to the guide rail 1G so as to cover the rail 16 ((+). The second frame 4 can be moved freely in the direction perpendicular to the plane of the paper in FIG. Yes, ball hair ring I9
allows the slide 1 to be performed smoothly.

Next, the operation of this device will be explained. First, as shown in FIG. 3, when the window is closed,
and glass plate 5) (1 is the kite rail 1)
iI! to cam 811 via 6! r, the contact force (C, the cam 8 is pushed to the position J), and the tension spring 14 is extended.

From this state, as shown in FIG. 5, when the open end of the window 20 (opposite the rotating shaft 7) is lifted up and opened, the load of the window 20 applied to the cam 8 is reduced, so that the tension 22 The spring 14 contracts and pulls the sliding shaft 1; 3 toward the ΦL shaft 7. Due to dirt, the sliding sleeve 13 does not rotate with the sleeve 13 in contact with the cam surface 9. The cam 8 moves along the hole 12 at a distance 7, and the cam 8 is lifted up about the rotating shaft 7.Then, when the window 20 is opened at 45 degrees, the angle regulating shaft 11 or the angle 1. The opening of the window section 20 is regulated by the opening of the window section 20.

In this state, when you release your hand from the window 20, the weight of the window 20 is applied to the cam 8 via the gail 16, and the cam 8 receives a force that rotates the rotating shaft 7 toward the center F force. However, window section 20
In the open state, the force acting on the cam 8 is small even when the window portion 20 is in the open state (+31a). It is larger than the force pushing up the cam 8 mentioned above.
As a result, the window portion 20 does not fall down and is maintained in the open state.

Note that when the opening angle of the window section 20 is increased to an included angle of 45 degrees or less, the self-weight moment of the window section 2oQ) that is applied to the force J8 changes, but the tension coil By setting the curved shape of the cam surface 9 in advance so that the force of the spring 4 changes, it becomes possible to hold the window 20 open at an arbitrary opening angle.

This skylight opening/closing structure has the following effects:

il + window 20 ("Angle of intention - C opening promotion 1.1 years old,
:, 1 can be done.

(2) The direction of rotation of the window portion 20 is the same as the direction of rotation of the cam 8 that transmits the force wheel to the tension coil spring 14;
Moreover, since the sliding shaft 13 rotates and moves along the cam surface 9, the force between the sliding shaft 13 and the cam surface 9 becomes extremely small, so that the opening and closing operations of the window portion 20 can be performed smoothly. At the same time, the durability of the shrine will be improved as no physical force is applied (3) As a result of the window 20 being able to be opened and closed smoothly, if a strong wind blows when the window is opened, it will be affected by the wind force. The window 20 closes automatically to prevent strong wind from blowing into the room.

(4) As shown in FIG. 7, when the connecting mechanism is placed outside the window 20, the total length becomes longer than the length W of the window 20. As shown, since the connecting mechanism is disposed below the end of the window portion 20, the overall length W can be shortened. Moreover, instead of installing the connection mechanism on the roof surface 22 via a spacer 21 as shown in FIG. Therefore, half of the roof surface 22 can also be abbreviated.

(5) Tension - The cover 8 c t of the cam 8 is applied to the inside of the window 14 or the inside of the window.
It also has excellent design properties and safety.

In addition, in the tenth embodiment, C connects the window frame 4 to the guide rail 1.
Although we have explained this in detail, this idea can be widely applied to ordinary skylights where the window frame 4 and guide rail 16 or the integrated four-ζ window section 20 does not slide. It is.

〔Effect of the invention〕

According to the skylight opening/closing structure of the present invention, the window section can be opened and closed smoothly, durability is increased, and the window section can be held open at a horizontal angle.
