Description

[Detailed Description of the Invention] This invention relates to a folding partition door, particularly a telescoping folding partition door suitable for use as an outer fence or for blocking traffic.

As prior art for this type of folding partition door, there are Japanese Utility Model Application No. 132939/1983 and Japanese Utility Model Application No. 54-78240.
There is something disclosed in the publication No.

However, these devices have a link or hinge on the top of the door that allows the door to extend and retract, making a scissor-like movement, so there is a risk of getting your hands stuck when opening and closing.

The present invention was developed in view of these circumstances, and its purpose is to avoid the danger of jamming your hands when opening and closing, and to have high self-sustaining stability.
The present invention also aims to provide a folding partition door of this type that is easily expandable and retractable.

Hereinafter, one embodiment of the foldable partition door according to this invention will be described in detail with reference to FIGS. 1 to 3.

Figure 1 shows the folding partition door according to this embodiment in an extended state. A pair of upper and lower connecting rods 1a consisting of a supported upper and lower pair,
1b, and the upper connecting rod 1a is
As shown in Fig. 2, the lower connecting rod 1b is rotatably supported on the pin shaft 2, and the lower connecting rod 1b is fixed to the pin shaft 2 via a screw. One end of one of the upper connecting rods 1a adjacent to the other lower connecting rod 1
At the other end of b, one end of one lower connecting rod 1b is connected to the other end of the other upper connecting rod 1a, respectively.
As shown in the figure, the pin shafts 3, 3 are rotatable, telescopic, and pivotally supported in a series, and on the pin shafts 2 of each of the upper connecting rods 1a, there is a fence post, respectively. When each shielding body 4 is a rod-shaped body such as a fence post, a chain, a chain, String body 5 such as rope
It is preferable that the shields be stretched so that the distance between the adjacent shields is slightly longer than the distance between the adjacent shields when the combination of the upper and lower connecting rods 1a and 1b is fully extended.

When constructing the folding partition door according to this embodiment, casters 6, 6, .
Alternatively, one side of the partition door may be fixed to an appropriate support as needed, but it is also possible to install a guide roller that rolls on a rail. All you have to do is to secure the mounting position by dropping the rod 7 into a bracket buried in the installation location, and in this state, by pulling the other side, you can freely expand and contract the door body to open and close it. .

In this way, when the door body is extended, the upper and lower connecting rods 1 of each series
a, 1b become a series, and each shield 4 also becomes a series, and can perform a sufficient restraining action as an outer fence or a roadblock.On the other hand, when contracted, the whole can be stored compactly. It will not obstruct traffic etc.

In addition, in the above embodiment, the fence post is attached to the central pin shaft of the upper connecting rod, but it is not necessarily necessary to attach it to this central part, and it is of course possible to attach it at any position. .

As described in detail above, according to this invention, a plurality of upper and lower connecting rods, each consisting of a pair of upper and lower connecting rods, are pivotally supported so that the central portions that intersect in a pantograph shape on a horizontal plane are relatively rotatable. The set is rotatable so that one end of one adjacent upper connecting rod connects to the other end of the other lower connecting rod, and one end of one lower connecting rod connects to the other end of the other upper connecting rod. They are pivotally supported in a series, making the whole structure expandable and retractable, and shielding bodies such as fence posts are erected on top of each upper connecting rod, so that the upper and lower parts of each set can be By applying force in the direction in which the connecting rods are connected, the door body can be expanded and contracted to open and close extremely easily, and when extended, it can function as an outer fence or as a roadblock, and when retracted, it can be stored compactly to prevent traffic from passing through. It is convenient to handle without getting in the way. In addition, the door itself has upper and lower connecting rods arranged downward, and a shield is erected on top of each upper connecting rod, lowering the center of gravity. The self-supporting stability is very good, and from a structural point of view, this is a relatively simple configuration in the middle and upper shield parts compared to the pantograph movement during telescopic operation in the lower connecting rod part. Because the door can be opened and closed, its movement is also a simple expansion and contraction operation, and since there is a space between the adjacent shields that does not allow your hands to get caught when closing the door, there is a possibility that your hands or fingertips will get caught during the opening/closing operation. You can avoid danger. Furthermore, the overall structure is relatively simple, and it can be provided easily and at low cost, which provides various practical effects.
