Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a folding door device in which a plurality of panels are foldably connected to each other via a joint and a frontage is opened and closed along upper and lower rails. .

(Prior Art) As is well known, a folding door device is configured such that a plurality of panels are foldably connected to each other through a joint. With the main slider protruding, the traveling tool travels on the upper rail and the main slider travels on the lower rail. When the auxiliary joint is folded, it will be kicked out from the upper and lower rails, but in order to perform a smooth opening and closing operation, engage and disengage the upper and lower rails of the auxiliary joint with good timing. It becomes important to do.
The running tool of the main joint and the main slider have the basic structure of a folding door, but various techniques have been developed in order to improve the engagement / disengagement operation with the upper and lower rails of the sub joint.

The "folding type telescopic door" relating to No. 2-36599 is also one of the conventional examples. This folding telescopic door has a guide roller that protrudes from the panel near the sub joint, while an auxiliary rail that guides the guide roller so that it does not pop out is provided along the upper rail. In M, the auxiliary rail is largely protruded from the upper rail. Further, a lock device and a folding device are provided in order to regulate the guide roller near the first auxiliary joint from the suspension base side.

By the way, the "foldable telescopic door" thus configured has the following drawbacks. First of all, one of the auxiliary rails has to be curved in a small area M on the suspension base side and largely protrudes from the upper rail, and the external appearance is unsightly and the installation work is troublesome. It must have a special ceiling structure for mounting. Further, when the number of panels increases, the small range M of the auxiliary rail that is curved and formed on the suspension base side becomes large. In this small range M, each folded panel has a fixed position. I can't stand still and I'm flapping. In other words, if the wind blows in, it will flap and grow naturally, narrowing the frontage width. Also, the guide roller does not enter the auxiliary rail at a predetermined position when the door is extended, so that the panel rebound phenomenon occurs and a smooth opening / closing operation cannot be obtained. When the folding door is further extended to close the frontage, the guide roller is guided by the auxiliary rail and the auxiliary joint is stable, but the main joint portion only suspended by the traveling tool is not always stable. Therefore, if the wind pressure acts on the panel surface, the main joint will be slightly loosened.

(Object of the Invention) Thus, the conventional folding door device still has the above-mentioned problems. The present invention is intended to solve these problems, and of course, opening and closing operations are smooth, and even when the frontage is closed or when the frontage is opened and folded, each panel has a backlash. Provide a stable folding door device.

(Structure of the present invention) The basic structure of the folding door device of the present invention is the same as before, and a plurality of panels are foldably connected through a joint, and a traveling tool is attached to the upper end of the main joint. A main slider is provided at the lower end, the traveling tool travels on the upper rail, and the main slider is guided by the lower rail. The present invention has the following features in order to solve the above problems.

In the folding door device of the present invention, a stopper block is provided on the upper rail on the hanging frame side, and the natural opening of the folding door is regulated by engaging with a main guide roller protruding from the upper end of the panel near the main joint. At the same time, it is possible to engage / disengage the panel and the rail at a predetermined position. Therefore,
On the upper rail, form a guide piece below the rail piece on which the traveling tool travels, delete one side (panel kick-out side) of the above guide piece by a certain distance from the hanging frame, and turn from that position to the pull frame. Auxiliary rails are provided alongside the auxiliary rails, and an entrance portion of the auxiliary rails has a shape in which a sub guide roller, which will be described later, can easily enter and exit, and an entrance piece and a folding block are attached thereto. Then, a stopper block is attached along the upper rail at a location where the guide piece is removed between the auxiliary rail and the suspension frame. The number of stopper blocks is not constant because it is related to the number of panels.
If it is a single panel, three stopper blocks will be attached at appropriate positions.

On the other hand, a guide roller or a guide block is provided so as to protrude from the upper end of each panel, but every other panel is counted, such as the first panel, the third panel, the fifth panel, etc., counting from the suspension frame side. Each of these panels is fitted with two guide rollers. One of them, the main guide roller, protrudes upward without protruding from the panel in the vicinity of the main joint, and the other one of the sub guide rollers is in the vicinity of the sub joint. Are differently protruding. That is, the sub guide roller is attached to the first panel, the third panel, the fifth panel, ...

By the way, the main guide roller and the sub guide roller are loosely fitted between the guide pieces of the upper rail and the auxiliary rail to guide the panel when the folding door is extended to close the frontage. Here, the folding rail device can be configured by removing the auxiliary rail and the auxiliary guide roller.

(Operation) In the folding door device of the present invention configured as described above, the frontage is opened and closed along the upper and lower rails as before, but each panel folded on the hanging frame side has a predetermined position. The main guide roller is positioned between the stopper blocks attached to the. Therefore, the pitch between the stopper blocks is set to a distance corresponding to about two panels thickness, and the main guide roller is provided in the stopper block so that the panel once folded does not naturally expand to reduce the front width. The movement is regulated.

Then, when pulling the pull tab and closing the frontage, at the same time as pulling the pull tab, the first auxiliary guide roller near the pull tab enters the entrance of the auxiliary rail and proceeds as it is. In this case also, the movement of the first main guide roller near the pull bar will be restricted by hitting the stopper block, but if the sub guide roller enters the auxiliary rail and the panel becomes almost parallel to the rail, The main guide roller passes through the stopper block, is released, and enters the upper rail. In this case, the sub guide roller can enter the entrance of the auxiliary rail because the main guide roller hits the stopper block and its movement is restricted.

In this way, the panels are sequentially stretched, the sub-guide rollers enter the auxiliary rails, the main guide rollers enter the upper rails, the folding doors are stretched, and the frontage is closed. When the frontage is completely closed, the first main guide roller on the suspension frame side contacts the inner surface of the stopper block to prevent the first panel from rattling. On the contrary, when folding each panel to open the frontage, the procedure is reversed.

On the other hand, when the auxiliary rail is not used, the auxiliary joint portion enters the upper rail and is guided as in the conventional folding door device.

Hereinafter, embodiments according to the present invention will be described in detail with reference to the drawings.

(Embodiment) FIG. 3 is a schematic view showing a folding door device of the present invention, and is generally the same as a conventional folding door device.

However, it is not limited to the inclined surface 18, and may be a smooth concave surface. Further, three stopper blocks 19a, 19b, 19c are attached to the upper rail 10 between the folding block 17 and the suspension frame 4, and the positions of these stopper blocks 19a, 19b, 19c are shown in the same figure. As shown, the panels 1a, 1b, ... Are arranged between the main guide rollers 12, 12, 12 in a folded state.

By the way, when the panels 1a, 1b ... Folded in this way are stretched to close the frontage, the puller frame 7 is attached to the puller frame 6.
Although it is pulled in the direction of (arrow direction), the panels 1f and 1e fall toward the upper rail 10 side following the movement of the pull bar 7.
In this case, the main joints 2a and 2b are prevented from moving because the main guide roller 12 contacts the stopper block 19, and only the two panels 1f and 1e are stretched. When the panel 1e is moved to the upper rail 10 side to some extent, the main guide roller 12 is released from the stopper block 19c and loosely fitted in the upper rail 10. That is, when the panels 1f and 1e are stretched, the main guide roller 12 is swung about the main joint 2b and released from the stopper block 19c. When the main guide roller 12 is loosely fitted to the upper rail 10, the panels 1f and 1e move along the upper rail 10 and stretch the next panels 1d and 1c, the operation of which is the panels 1f and 1e. Is the same as in. If the panels 1f and 1e are stretched to rotate counterclockwise about the main joint 2b, the auxiliary guide roller 13 attached to the upper end of the panel 1e is also rotated to rotate the auxiliary rails. Intrude into entrance 15 of 14. Since the center of the pivoting panel (main joint 2) is almost determined by the stopper block 19c, the auxiliary guide roller 13 can always enter the inlet 15, and the auxiliary guide roller 13 is arranged at a position where it can enter. To be done.

FIG. 2 shows a state in which all the panels 1a, 1b ... are stretched and the frontage is closed, and the main guide rollers 12, 12 ... are the upper rails.
