Description

[Detailed explanation of the idea] [Industrial application field]

The present invention relates to an opening degree regulating device that locks the door plate A and door plate B of a storm door at an appropriate angle using a locking hole provided in a turntable and a locking pin on the door plate side.

[Conventional technology]

Fig. 1 shows an example of a double-opening folding shutter. In such a folding shutter, a door plate A is rotatably attached to the vertical frame side of the sash by upper and lower pivot pins 1, 1, By folding the door plate B hinged to the door plate A and rotating it 180 degrees as shown in Figure 2, the wall surface 2
It can be placed in the open position. At this time, it is necessary to select and regulate the opening degree to 180° or 90°. For this purpose, an opening limiter 5 is installed. Conventionally, as seen in Japanese Utility Model Application No. 57-96388, a latch (latching pin in the present invention) is held by a spring in order to maintain the locked or unlocked state. To do this, it was necessary to provide a notch groove in the part of the latch that required the most strength.

[Problem that the idea aims to solve]

However, if the opening angle of the door plate is 90 degrees, for example, the door plate locking pin needs to have considerable wind pressure strength, and a simple drop lock will not have enough strength. To this end, we considered a structure that would avoid cutouts and other factors that would reduce the strength of the parts where the locking pin is loaded.

[Means to solve the problem]

As a result of considering the above issues, we found that door panels A and B in a storm door that can be rotated 180 degrees until they are folded and flush against the wall are fixed at appropriate angles using locking holes provided on the turntable and locking pins on the door panel side. In a folding storm door, which is an opening regulating device to be locked, and which is provided so that the locking pin is interlocked with the vertical stile on the joining side of door panel B or the horizontal stile knob near the vertical stile, the locking pin near the upper end of the locking pin 7 is An opening regulating device for a folding rain door, characterized in that protrusions 14, 15 on the outside of bifurcated pieces 9, 10 of a knob 8, which are held from both sides with respect to the neck part, serve as stoppers for overcoming vertical position regulating springs 13, 12. was developed.

[Effect]

With such a structure, the knob 8 can be attached to the locking pin 7 with one touch by means of the forked pieces 9 and 10. The position regulating springs 12 and 13 act on the protrusions 14 and 15 of the bifurcated pieces 9 and 10 of the knob 8 even if the locking pin 7 does not have a notch groove or the like to maintain the locked or unlocked state. This prevents the locking pin 7 from falling downward.

【Example】

The present invention will be explained in detail below with reference to the drawings. FIG. 1 is a front view of a double folding storm door, and FIG. 2 is a cross-sectional view showing the door plate in a folded state.
FIG. 3 shows a specific example of the opening limiter, in which a is a plan view, b is a front view, c is a rear view, and d is a side view when attached to a side stile. FIG. 4 is a perspective view of the same. In these figures, the illustrated opening limiter 5 is provided on the lower stile 3 of the door plate B on the door roller side, but it can also be provided on the vertical stile. The door plate A and the door plate B are hinged, and the door plate A is pivoted to the turntable 4 by the aforementioned pivot pin 1, and the door plate B
is fixed by the opening limiter 5 of the present invention. The opening limiter 5 is a locking hole 6 provided in the turntable 4.
It is locked by a locking pin 7, the specific structure of which is shown in FIGS. 3 and 4. In this case, the neck of the locking pin 7 is held between the long piece 9 and the short piece 10 of the knob 8. In FIG. 3a, the two-dot chain line shows how the locking pin 7 is held with one touch. The case 11 of the opening limiter 5 is open on one side and has a window at the rear, with pin insertion holes 1 in the middle and bottom.
It is supported at two points with pins 6 and 17, from which the lower end of the locking pin 7 protrudes. Case 11
Upper and lower position regulating springs 12 and 13 are provided on both sides of the inside of the knob 8, and a protrusion 14 as a stopper is provided on the outside of the long piece 9 of the knob 8, and when the knob 8 is raised from the bottom, The upper position regulating spring 13 prevents the locking pin 7 from falling downward by passing over the protrusion 14. The long piece 9 of the knob 8 protrudes considerably rearward from the window of the case 11, as shown in Figs. 2 and 3d, and protrudes from the lower stile 3 to which the case is fixed to the outside (inner side). . Therefore, the projecting end can also be used for vertical movement.
A protrusion 15 is also provided on the short piece 10 of the knob 8, and when the knob 8 is lowered from the top, the lower position regulating spring 12 rides over the protrusion 15 and restricts the locking pin 7 from rising upward. .

[Effect of the idea]

Since the opening limiter of the present invention has the above-described structure, it has the following features. When the shutters are folded, the knobs can be operated from the outside, so there is no risk of your fingers getting jammed. The structure is simple, the number of parts is small, and the knob can be installed with one touch. Unlike conventional products, the locking pin does not have a notch and a regulating spring acts on the locking pin, so the pin strength is high. By installing the horizontal stile at a position far from the vertical stile, the distance from the fulcrum increases, so the wind pressure strength increases.
