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 outside fence or as a roadblock. It is an object of the present invention to provide a folding partition door of this type with good telescoping operability.

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

Fig. 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,
As shown in FIG. 2, the upper connecting rod 1a is rotatably supported on the pin shaft 2, and the lower connecting rod 1b is connected to the pin shaft 2 via a screw. A plurality of sets of upper and lower connecting rods are connected such that one end of one of the mutually adjacent upper connecting rods 1a connects to the other lower connecting rod 1b.
At the other end, one end of one lower connecting rod 1b is connected to the other end of the other upper connecting rod 1a, as shown in FIG. Moreover, they are pivotally supported in a series, and fence posts 4 are fitted and fixed onto the pin shafts 2 of each of the upper connecting rods 1a, respectively.
Between each of these adjacent fence posts 4, a string 5 such as a chain or rope is connected at a distance that is wider than the distance between the adjacent fence posts when the combination of the upper and lower connecting rods 1a, 1b is extended to the maximum. It was strung up so that it was long.

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 end, you can freely expand and contract the door body to open and close it. .

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 detailed 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 their central portions that intersect in a pantograph shape on a horizontal plane are relatively rotatable. The set is rotatably attached to one end of one adjacent upper connecting rod and the other end of the other lower connecting rod, and one end of one lower connecting rod is attached to the other end of the other upper connecting rod. The structure is pivoted in a series so that the whole structure is expandable and retractable, and fence posts are erected on each upper connecting rod, and chains and ropes are connected between each of these adjacent fence posts. Since the strings are stretched, the door body can be opened and closed very easily by applying force in the direction in which the upper and lower connecting rods of each set are connected. In addition, the door itself has upper and lower connecting rods placed in a row downwards, and fence posts are erected on top of each upper connecting rod, lowering the center of gravity. Not only is the self-supporting stability extremely good, but compared to the pantograph movement during telescoping in the lower connecting rod, the intermediate and upper fence posts have large spaces between each other. Since the fence posts only move by expanding and contracting the interval, it is possible to avoid the risk of getting your hands, fingertips, etc. caught during opening and closing operations. Furthermore, since a string such as a chain or rope that is longer than the maximum extension interval is stretched between each adjacent fence post, when it is extended, each string connects each fence post. The strings can be stretched loosely at a convenient height, and when contracted or folded, each string hangs down between the fence posts closer together and is stored compactly, making it easier for traffic, etc. There is no risk of interference, it is convenient to handle, the overall structure is relatively simple, and it can be provided easily and at low cost, which has various practical effects.

Claims (1)

[Scope of utility model registration request] A pair of upper and lower connecting rods are provided, each consisting of a pair of upper and lower connecting rods, which are pivotally supported so that their central portions intersecting in a pantograph shape on a horizontal plane are relatively rotatable, and multiple sets of these upper and lower connecting rods are provided. One end of one mutually adjacent upper connecting rod is rotated to the other end of the other lower connecting rod, and one end of one lower connecting rod is rotated to the other end of the other upper connecting rod, respectively. They are telescopic and pivoted in a series, and fence posts are erected on each of the upper connecting rods, and strings such as chains and ropes are connected between adjacent fence posts. A folding partition door characterized by being stretched longer than at least the maximum extension interval between fence posts.
