Description

[Detailed Description of the Invention] The present invention relates to a gate made of a door body which is made horizontally expandable and retractable by pivoting the intersections of diagonal beams intersecting each other in a pantograph shape.

Retractable so-called accordion gates have been widely used in recent years because the door body can be opened and closed in a straight line and does not require extra open space.

In this telescopic gate, the door body is rotatably attached to the gate post via a hinge metal fitting and a hanging metal fitting, and if the door body is reduced and rotated, waste due to the folded width of the door body can be reduced. It also has the advantage that the entire opening width can be used.

However, depending on the installation location, it may be necessary to attach the door body to the gate post in a fixed, unrotatable manner so that the door body can be opened and closed only in a straight line.

The present invention attempts to provide a telescoping gate that allows the door body to be fixedly attached to the gate post by using an anti-rotation metal fitting so that it cannot easily be rotated, thereby allowing the door body to be opened and closed only in a straight line. It is something.

For this purpose, in the present invention, the hinge fitting is mounted by overlapping the Hishitsubo rotation stopper on the outside of the plate part, and the lower bolt hole of the Hishitsubo rotation stopper and the hinge fitting are attached to the plate part. In addition to tightening and fixing with bolts and nuts inserted into the gate post through matching holes with the bolt holes, the hanging fittings connected to the hinge fittings are installed by overlapping the plate part on the outside of the Hishitsubo rotation stopper fitting. To install the upper bolt hole of the Hishitsubo rotation stopper and the hanging bracket, insert the screw into the matching hole of the bolt hole of the plate part from the side plate bolt hole of the door body while cutting a tap, and then tighten the fixed bolt and this bolt. It is characterized by a structure in which the door body is connected to the gate post so that it can be opened and closed only in a straight line by means of a nut attached thereto.

The present invention will be explained below with reference to FIGS. 1 to 7.

First, we will give an overview of the gate according to the present invention, its front view as an example,
This will be explained with reference to FIGS. 1 and 2, which show plane views.

As shown in the figure, when attaching the gate body 1, which is horizontally expandable and retractable, to the gate post 2, the hinge metal fitting 4 on the gate post 2 side and the door body 1 are connected to each other via the hinged pivot fitting 3. The hanging fitting 6 on the side frame 5 of
can be opened and closed only in a straight line with respect to the gatepost 2.

Note that the door body 1 in this example has the diagonal bars 7 intersecting each other in a pantograph shape, pivoting at the intersections so that it can be expanded and contracted laterally, and the lower end of the intermediate vertical bar 8 and the movable vertical frame. Although a case is shown in which casters 10 are attached to the lower ends of gates 9 and 9, the proposed gate is not located on the door body itself, so the door body 1 only needs to be configured to be able to expand and contract in the horizontal direction. , but is not limited to the illustrated door body.

Usually, the door body is rotatably connected to the gatepost.

That is, the hinge fittings 4 are installed at predetermined positions above and below the gate post 2, and the hinge fittings 4 are attached to the gate post 2 through horizontally long bolt holes 4b drilled in the plate portion 4a.
It is tightened and fixed by bolts 11 and nuts 12 inserted through the door body 1, and hanging fittings 6 are installed at predetermined positions above and below the side frame 5 of the door body 1.
is installed by tightening and fixing the bolts 13 and nuts 14 inserted into the side frame 5 through the cross-shaped bolt holes 6b drilled in the plate portion 6a, and connecting the connecting portion 4C of the hinge metal fitting 4 and the connecting portion 6C of the hanging metal fitting 6.
The door body 1 is attached to the gate post 2 by rotatably connecting the gate body 1 to the gate post 2, thereby making it possible to open and close the door body 1 linearly with respect to the gate post 2. A normal telescopic gate is one that rotates relative to 2 so that the entire opening width can be used.

However, depending on the installation location, it is necessary to attach the door body 1 to the gate post 2 in a fixed, unrotatable manner so that the door body 1 can be opened and closed only linearly.

Therefore, in the proposed gate, the hinge fitting 4 and the hanging fitting 6 are fixedly connected using the hinge fitting 3 shown in FIGS. 3 and 4, and the door body 1 is aligned with the gate post 2. It can be opened and closed by expanding and contracting only at the target.

To be more specific, the hinge fitting 4 is attached to the lower part of the rectangular plate by drilling an oblong bolt hole 3a corresponding to the oblong bolt hole 4b drilled in the plate part 4a.
At the center of the upper part, a vertically long bolt hole 3b that matches the cross-shaped bolt hole 6b of the plate part 6a is opened to attach the hanging fitting 6, and the door body 1 can be rotated with respect to the gate post 2 by means of this tail rotation stopper fitting 3. For fixed, immovable mounting, the procedure is as shown in FIGS.

That is, the hinge fitting 4 is installed by overlapping the crimp rotation stopper 3 on the outside of the plate portion 4a, and connecting the horizontally long bolt hole 3a at the bottom of the screwpot rotation stopper 3 to the horizontally long bolt hole 4b of the hinge fitting 4. and gate post 2 from this matching hole.
By tightening the bolt 11 and nut 12 inserted in
Connecting portion 6C with the bolt 15 and nut 16 (see Fig. 5). From this state, the hanging fitting 6 can be attached by rotating the plate portion 6a and stacking it on the outside of the rotation stopper fitting 3. At the same time, the vertically long bolt hole 3a on the upper part of the rotation stopper 3 is matched with the cross-shaped bolt hole 6b of the plate part 6a, and the side frame 5 of the door body 1 is attached to the plate part 6a. To attach the hinge fitting 4 to the gate post 2, hold the plate part 6a and attach the bolts 13 from the outside of the side frame 5, overlapping each other. The vertically long bolt hole 3a of the rotation stopper 3 and the hanging fitting are attached to the corresponding hole with the cross-shaped bolt hole 6b of the plate part 6a.
and screw it in while cutting the tap until the tip touches the surface of the gate post 2 through the matching hole and fix it,
A nut 14 is tightened to the fixed bolt protrusion (see FIGS. 6 and 7), thereby connecting the door body 1 to the gate post 2 so that it can be opened and closed only in a straight line.

Therefore, the proposed gate can be easily installed by simply interposing the Hishitsubo rotation stopper 3 without making any structural changes to the conventional hinge metal fittings and hanging metal fittings. The hanging fitting 6 is connected in a fixed manner that cannot be rotated.
Therefore, since the gate body 1 is configured to be able to open and close by expanding and contracting only in a straight line with respect to the gate post 2, it is suitable for installation in a place where the door body needs to be opened and closed only in a straight line. Moreover, if a rotation stopper is prepared separately, the extendable gate with the same structure can be either a rotation type or a linear type, which can also contribute to reducing the inventory burden.
