Description

[Detailed Description of the Invention] <Industrial Field of Application> The present invention relates to an opening/closing device for a storm door that can be opened and closed from both sides near the center of a bay window of a house by connecting a plurality of panels with hinges.

<Prior Art> Various proposals have been made regarding opening/closing devices for bay window shutters. Among them, technologies similar to the present invention include Utility Model Application No. 58-73883 and No. 58-73883;
No. 73884 can be exemplified. These known opening/closing devices for bay window shutters have a structure in which an operating lever for opening/closing or maintaining (locking) the shutter in an open state moves along a rail groove provided in a guide rail.

<Problems that the invention aims to solve> Therefore, with conventional devices, when the shutter suddenly closes due to a gust of wind, etc., one has to jam one's hand between the rail and the lower stile of the shutter, and the length of the operating lever is limited, resulting in the shaft Since the panel is fixed close to its origin, there is a lot of wobbling when it is opened.Furthermore, a common problem with this type of bay window shutter is that the corner Z of the bay window (i.e. the guide rail) At the joint), it is difficult to slide the guide pin provided on the front panel B4, which is hinged to the side panel A2 pivotally attached to the wall base and folded into the room. are doing.

<Means for solving the problems> The present invention solves the above-mentioned problems, and for this purpose, the lower stile 9 of the front panel C5
An operation lever receiving block 10 is provided inside the nearby room,
On the top surface of this operation lever block 10 is a front panel B.
An acute-angled groove 11 is provided on the connection side with 4,
We have newly developed an opening/closing device that has an operating rod 13 that can be lowered into the groove 11.

<Function> Such a bay window shutter opening/closing device allows the operating rod 13 to be left standing along the panel when the shutter is closed, and the operating rod 13 to be held horizontally or at an angle that is easy to operate when opening/closing the shutter. In this case, the operating rod 13 allows the guide pin 3 to pass over the joint of the rail at the corner Z of the bay window.
This can be easily achieved by manual operation on the panel side.

<Examples> Examples of the present invention will be described in detail below with reference to the drawings.

FIG. 1 is a plan view showing how a bay window shutter opening/closing device is provided. Figure 2 shows the X in Figure 1.
-X enlarged sectional view. FIG. 3 is an enlarged view of the P section. FIG. 4 is an enlarged view of the Q section. FIG. 5 is a sectional view taken along YY line in FIG.

The general structure of a shutter equipped with the bay window shutter opening/closing device of the present invention is as shown in Figure 1.
Side panel A2 with pivot 1 at the wall side base
, a front panel B4 which is hinged to the side panel A2 and folded to the inside of the room and has a guide pin 3 at the tip; and a front panel C5 which is hinged to the front panel B4 and folded to the outside of the room. The three panels constitute a window on one side from the center of the bay window 6, and the structure is such that it can be moved along a guide rail 7 to open and close.

As shown in FIG. 2, the opening/closing device 8 of the present invention installed in such a bay window shutter has an operation lever receiving block 10 provided on the inside of the room near the lower stile 9 on the inside of the room on the front panel C5. . As shown in FIG. 3, the upper surface of the operating lever receiving block 10 is provided with a groove 11 at an acute angle and in a horizontal direction relative to the side connected to the front panel B4, and a vertical hole 12 at the base thereof. The operating rod 13 is inserted into the vertical hole 12 and can be lowered into the groove 11. for that,
As shown in FIG. 5, a pin 14 protruding to both sides is provided at the end of the operating lever 13, and furthermore, a group hole 15 is arranged in parallel to the vertical hole 12 of the operating lever receiving block 10. When the operating rod 13 is turned vertically and lowered, the pin 14 descends to the lower part of the group hole 15, and when the operating rod 13 is pulled up, the pin 14 moves up within the group hole and becomes a rotation axis. By this,
When the shutter is closed, the operating rod 13 can be stored in an upright position along the panel, and when the shutter is opened or closed, the operating rod 13 can be placed horizontally or vertically as shown in FIGS. 1 and 4. Can be used at any angle that is easy to operate. In contrast, the same function can be obtained by fixing a pin to the operating lever receiving block 10 and providing an elongated hole at the tip of the operating lever 13. Furthermore,
The operating lever receiving block 10 may have only the groove 11 and the rotating shaft, and an elastic clip may be provided on the panel side to hold the tip of the operating lever in the stored state.

The operating method of the bay window shutter opening/closing device of the present invention is explained with reference to FIG.
When the shutters shown in are closed, the fifth
As shown in the figure and as described above, the operating rod 13 can be stored in an upright position along the front panel C5. Next, when opening the shutters, as shown by the two-dot chain line in the center of FIG.
Fold it horizontally along the groove 11, and then fold it into three as you move towards the right in the figure. At this time, the panel can be guided by the operating rod 13 so that the guide pin 3 moves smoothly within the rail. In order to maintain the fully open state of the shutters stably, a locking means 14 such as a protrusion or a fixing metal fitting is provided so that the end of the operating rod 13 is locked to the corner Z of the bay window. Operation lever 1 to this locking means
It is important that the mounting angle of the operating lever receiving block 10 be in the direction described above in order to be able to lock the lever 3 and to allow the guide pin to easily get over the corner Z.

<Effects of the invention> The bay window opening/closing device of the present invention described in detail above is safe even when a gust of wind blows during opening/closing, and since the panel can be fixed far from the axis, there is no rattling when opening, and furthermore, the front The guide pin provided on the panel B4 can be easily moved by being guided by the operating rod.
