The folding door has an advantage that a wide boundary of a frontage of a parking lot or the like can be closed, and the storage space of the door is small. However, on the other hand, the folding doors of the prior art have the following disadvantages that are not found in ordinary sliding doors and the like. That is, the conventional folding door has a problem in that when the frontage is opened, each door piece is randomly spread.
Ideally, the folding doors are folded in order when opening the frontage to take up no storage space. However, in the folding door of the related art, since the door pieces are simply joined by hinges, the folding door also bends in a direction opposite to the direction in which the door is originally intended to be bent against the intention of the user. Therefore, when opening the frontage, doors often jump out of the premises, causing trouble to the neighborhood. Further, in order to avoid such a troublesome neighborhood, it is necessary to carefully fold the door pieces one by one when opening the frontage. Therefore, the conventional folding door has a problem that the opening and closing workability is extremely inferior to that of a sliding door or the like. Furthermore, the folding doors of the prior art have the disadvantage that locking is difficult. That is, the folding doors need to be fixed so that each door piece does not move in order to lock because each door piece is pivoted by a hinge, and it is possible to lock all door pieces in a fixed state by locking in one place. Have difficulty.

The present invention focuses on the above-mentioned disadvantages of the prior art, and when the frontage is opened, each door does not spread,
Another object of the present invention is to provide a folding door that can be easily locked. Another object of the present invention is to provide a folding door that can be easily constructed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Specific embodiments of the present invention will be described below. FIG. 1 is a top view of a folding door according to a specific embodiment of the present invention. FIG. 2 is an enlarged view of a main part of FIG. FIG.
FIG. 3 is a view in the direction of arrow A in FIG. 2. FIG. 4 is a top view of a modified embodiment of the present invention in which the frontage is closed by a folding door. FIG. 5 is a top view in a state where the frontage is opened by the folding door of FIG. 4.

1 to 3, reference numeral 1 denotes a folding door of the present invention. The folding door 1 of the present embodiment closes a frontage of a parking lot, and has two door pieces 3 and 4 attached to a gate post (fixing member) 2. The folding door 1 is opened and closed by folding the door pieces 3 and 4. The configuration itself of the gate column 2 and the door pieces 3 and 4 employed in the present embodiment is not much different from that of a normal folding door. That is, the gate column 2 is made of a square pipe, and the lower end is embedded in the foundation and becomes independent. One-sided doors 3, 4
Has a fence shape, as partially shown in FIG.

Hinges 5 and 6 are attached between the gate post 2, the door strip 3 and the door strip 4, respectively, and the door strip 3 can swing with respect to the gate post 2 via the hinge 5. The door piece 4 can swing with respect to the door piece 3 via the hinge 6.

The characteristic structure of the folding door of this embodiment is as follows.
It has an auxiliary rod 8, and the above-mentioned gate pole 2, door piece 3, and door piece 4 are linked by the auxiliary rod 8. Hereinafter, this characteristic configuration will be described in detail. The auxiliary rod 8 is provided with a gate pole-side mounting portion 10 at one end of a rod body 9 and a door-side mounting portion 11 at the other end.

Here, the gate-post-side mounting portion 10 is a cylindrical member, and a slit 12 (see FIG. 3) is formed on the end face. In addition, a hole 13 is provided on the tip end side of the gate pole side attachment portion 10. This hole 13 penetrates the slit 12 described above. A female screw hole is provided on the other end surface of the gate pole side mounting portion 10, and a male screw provided at the tip of the rod body 9 is fitted. Therefore, in the auxiliary rod 8 employed in the present embodiment, by adjusting the amount of screwing of the rod body 9 into the column-side mounting portion 10, the auxiliary rod 8 can be adjusted.
Can be varied in length.

The door-side mounting portion 11 is integrally mounted on the other end of the rod body 9 via a pin 15. A slit 16 is also provided on the end surface of the door-side mounting portion 11, similarly to the gate-post-side mounting portion 10 described above. The door-side mounting portion 11 is provided with two through holes 17 and 18 on the same plane, which are arranged in the longitudinal direction. The hole 18 on the inner tip side penetrates the slit 16.

The above-mentioned auxiliary rod 8 is used for the gate-side bracket 2.
0, and is attached to the gate post 2 and the door piece 4 via the door side bracket 21. Here, the gate side bracket 20
The door-side bracket 21 has a vertical plate portion 23 and a horizontal plate portion 25 integrated with each other, as is apparent from FIGS. The vertical plate portion 23 is a portion to be attached to the gate post 2, and has a long hole 26 for attachment and position adjustment. On the other hand, the horizontal plate portion 25 is provided with a hole (not shown).

The gate post side bracket 20 has a vertical plate portion 23 sandwiched between the hinge 5 and the gate post 2, and is fixed to the gate post 2 by a screw 28 common to the hinge 5. The horizontal plate portion 25 of the gate post-side bracket 20 is inserted into the slit 12 provided in the gate post-side mounting portion 10 of the auxiliary rod 8. A groove-shaped cover member 19 is attached to a connection portion between the horizontal plate portion 25 of the gate post-side bracket 20 and the gate post-side mounting portion 10 of the auxiliary rod 8. Further, through the cover member 19, a pin 27 penetrates through the hole 13 provided in the gate pole side attachment portion 10 and the hole (not shown) of the horizontal plate portion 25.
For this reason, the auxiliary rod 8 is connected to the gate column 2 by a rotating pair with a pin 27. An adjusting screw 29 is attached to the front side of the cover member 19. Adjustment screw 29
Has a front end projecting into the groove of the cover member 19 from the front side, and can abut on the gate post-side mounting portion 10 of the auxiliary rod 8.

Looking at the door piece 4 side, the door piece side bracket 21 has a vertical plate portion 30 and a horizontal plate portion 31 integrated. The horizontal plate portion 31 has a hole (not shown). The door plate side bracket 21 has the vertical plate portion 30 fixed to the door plate 4 with screws 33. The horizontal plate portion 31 of the door-side bracket 21 is inserted into a slit 16 provided in the door-side attachment portion 11 of the auxiliary rod 8. The pins 35 are inserted into the holes of the horizontal plate portion 31 and the door-side attachment portion 11. Therefore, the auxiliary rod 8 is connected to the door piece 4 by a rotating pair with the pin 35.

As described above, the gate post 2 and the doorpiece 3 are connected by the hinge 5, and the doorpiece 3 and the doorpiece 4 are connected by the hinge 6.
The hinge 6 and the auxiliary rod 8 are connected by a pin 35, and the auxiliary rod 8 and the gate post 2 are connected by a pin 27. Therefore, in the folding door 1 of the present embodiment, each member of the gate post 2, the door piece 3, the door piece 4, and the auxiliary rod 8 constitutes a series of four-node rotating chains.

In FIG. 3, a member indicated by reference numeral 38 is a drop-down member, which has a pin 39, and locks the folding door 1 by lowering the pin 39 as described later.

Next, the operation of the folding door 1 of this embodiment will be described. The state when the frontage of the parking lot is closed by the folding door 1 of the present embodiment is as shown by the solid line in FIG. That is, the door pieces 3 and the door pieces 4 are almost linearly spread. At this time, the auxiliary rod 8 is at a position substantially parallel to the door pieces 3 and 4. Here, to open the frontage,
When the door piece 4 or the door piece 3 is bent, in the folding door 1 of the present embodiment, the constituent members constitute a series of four-section rotating chains, and the gate post 2 is fixed. Functions as a limited chain. That is, doors 3, 4
Can move only on a limited trajectory.

More specifically, when the door piece 3 is swung about the hinge 5 so as to be folded, the door piece 4 moves accordingly. Then, the pin 35 integrated with the door piece 4 moves. However, the pin 35 moves together with the auxiliary rod 8. Then, since the auxiliary rod 8 swings around the pin 27 serving as a fixed fulcrum, the pin 35 moves along an arc locus 36. Therefore, as the door 3 moves, the door 4 gradually bends with the road side convex. Finally, the door piece 4 becomes parallel to the door piece 3.

In the above description, the case where the door piece 3 is forcibly bent will be described as an example.
Has been described, the folding door 1 of the present embodiment is explained.
Since each of the constituent members forms a four-bar chain, even if the door piece 4 is moved by hand, the door pieces 3 and 4 follow the same trajectory as described above.

Next, a method of locking the folding door 1 of the embodiment will be described. When locking the folding door 1, the door piece 3 and the door piece 4 are naturally extended linearly, and the frontage of the parking lot is closed. Here, the folding door 1 of the present embodiment
In this embodiment, a cover member 19 is attached to a connection portion between the gate post-side bracket 20 and the auxiliary rod 8, and the auxiliary rod 8
Does not lean to the parking lot side beyond a certain angle. Therefore, the door piece 3 and the door piece 4 of the folding door 1 do not bend to the parking lot side beyond the straight state. Then, the dropper 38 attached to the door piece 3 is lowered, and the tip of the pin 39 is inserted into the through hole 18 of the auxiliary rod 8. Then, the three members of the gate post 2, the door piece 3, and the auxiliary rod 8 are joined by three rotating pairs of the hinge 5, the pin 39, and the pin 27 to form a fixed chain. Therefore, the door piece 3 loses the degree of freedom and is fixed.

In addition, the door piece 4 is connected to the door piece 3 and the auxiliary rod 8 by the hinge 6 and the two rotation fulcrums of the pin 35, and moves as the door piece 3 moves as described above. Eventually, the door piece 4 also loses its degree of freedom and is fixed. The position shown in the present embodiment is recommended as the mounting position of the drop-down unit 38 because the gate post 2, the door piece 3 and the auxiliary rod 3 are connected in a triangular form to form a fixed chain and have the least rattling. You.

However, if some backlash is tolerated, it is possible to attach a drop to another position.

That is, the drop is attached to the gate post 2, and a hole is provided in the gate pole side attachment portion 10 of the auxiliary rod 8,
Even if a pin for dropping down is inserted into the hole, the folding door 1 can be locked. Similarly, the folding door 1 can be locked even when the drop door is attached to the door piece 4 and the pin for dropping the door is inserted into the hole of the auxiliary rod 8. In the former case, the swing of the auxiliary rod 8 is regulated by the drop-down pin. In the latter case, the angle change between the door piece 4 and the auxiliary rod 8 is regulated by the drop-down pin. It is.

In the above-described folding door 1 of the present embodiment, the elongated plate 26 of the
Has been disclosed. The reason for providing such an adjustment point is that in this type of door, adjustment of the gap between the door piece 3 and the gate post 2 and the like are usually performed at the installation site. It is intended for. In addition, the folding door 1 employs a configuration in which the entire length of the auxiliary rod 8 can be changed by a screw. This is also for facilitating on-site adjustment as described above. Such consideration for facilitating adjustment at the installation site is preferable in designing such a folding door.

For the folding door 1 described above, the configuration in which the simplest door piece is two has been disclosed in order to facilitate the explanation. However, the invention can of course also be applied to folding doors having more than two door pieces. 4 and 5 show a case where the present invention is applied to a folding door having three door pieces. Folding door 40 of the present embodiment
Is provided with three door pieces 41, 42, 43. And the gate post 45 and the door pieces 41, 42, 43 are hinged 46, 47,
48.

The folding door 40 of this embodiment has two auxiliary rods.
Have a book. The auxiliary rod 50 is a straight line like the auxiliary rod 8 of the previous embodiment, and has a length adjusting portion 52 formed by a screw in the middle. This adjusting part 52 is provided with the auxiliary rod 8 described in the previous embodiment.
The structure is the same as that of the connecting structure between the rod body 9 and the column-side mounting portion 10. The other auxiliary rod 53 employed in the folding door 40 of the present embodiment has a branch portion 55 near the end, and has a total of three ends. In addition, of the door piece 43 at the tip,
An extension bracket 57 is integrally attached to an end on the door piece 42 side. An elongated hole 58 is formed at an end of the extension bracket 57.

In the folding door 40 of this embodiment, the auxiliary rod 5
0 is connected at one end to the gate post 45 by a pin 60. The other end of the auxiliary rod 50 is connected to a branch end of the auxiliary rod 53 by a pin 61. One end of the auxiliary rod 53 is connected to the door piece 41 by a pin 62. The other end of the auxiliary rod 53 is engaged with the elongated hole 58 of the extension bracket 57 by the pin 63, and
The auxiliary rod 53 is connected to the door piece 41 via the.

The folding door 40 of the present embodiment has the above-described configuration, and has a series of four-bar rotating chains having the gate post 45, the door piece 41, the auxiliary rod 53 (between the pin 62 and the pin 61) and the auxiliary rod 50 as elements. Is configured. Similarly, a series of four-joint rotary chains having the door piece 41 (between the pin 62 and the pin 47), the door piece 42, the door piece 43 (the extension bracket 57), and the auxiliary rod 53 as elements are configured.

In the folding door 40 of the present embodiment, since each of the constituent members constitutes two sets of four-bar rotating chains, the door pieces 42,
Each of the door pieces 43 moves along a limited trajectory. That is, when any one of the door pieces 41, 42, 43 is moved from the time when the door pieces 41, 42, 43 are in a linear state, each of the door pieces 41, 42, 43 always draws a fixed locus. Bends. Finally, as shown in FIG. 5, they are all stored in parallel.

In the folding door 40 of this embodiment, the door piece 43
And the auxiliary rod 53 are connected via the long hole 58. Such a measure of providing a long hole in one of the members forming the rotating pair is recommended as a method of absorbing a dimensional error or the like of each member. That is, the folding door of the present invention can theoretically be constituted by using only a rotating pair having a very small gap such as a ball bearing.

However, the hinges used in this type of door usually have large fitting tolerances, and each door piece has a large backlash. For this reason, employing a small-gap rotation pair at the end of the auxiliary rod often results in excessive quality in balance with other hinges. In particular, in a configuration in which a plurality of four-bar rotation chains are combined as in the present embodiment, it is not possible to employ a small-gap rotation rod at the end of the auxiliary rod,
This is a factor that makes the operation of the door piece awkward. Therefore, in a folding door having a plurality of four-bar rotating chains as in the present embodiment, it is desirable that any one of the rotating pairs has a large backlash.

[0035]

[Effect of the invention] The folding door of the present invention has one door piece,
Other door pieces or fixing members are linked by auxiliary bars. Therefore, the degree of freedom of each door piece is small, and therefore, when opening the frontage, each door piece does not spread randomly. Therefore, the folding door of the present invention has the effect of not disturbing the neighborhood. In addition, the folding door of the present invention has an effect that the opening and closing are smooth and the workability is excellent. Further, in the folding door of the present invention, the door piece can be fixed by operating the drop-down attached to the door piece or the like to engage with the hole of the auxiliary rod. Therefore, the folding door of the present invention is easy to lock.

In the folding door according to claims 2 and 3,
Since the doors and the like make up a four-bar rotating chain,
It becomes a limited chain and only a certain movement is possible. Thus, when one of the door pieces is moved, each door piece operates in a limited manner and is folded in an orderly manner. Therefore, the effect of the folding door of the present invention is that the door pieces do not spread out randomly. In addition, in the folding door of the present invention, the length and the mounting position of the auxiliary rod can be adjusted, and the operation is smooth and the construction is easy.
