Description

[Detailed Description of the Invention] [Industrial field of application] According to the present invention, when a movable column is moved to a fixed column, an expandable body located between both columns is folded and stored inside the fixed column and the movable column. It is related to the expandable retractable gate.

[Prior Art] In the gate that opens and closes when the door expands and contracts, since the expansion and contraction members are combined in an X shape, a V shape, a zigzag shape, etc., when they are opened, they are folded and bundled on the side of the fixed pillar. , When it is closed, it expands to the side in conjunction with the movable pillar that runs on the rail and becomes a tilted shape (eg.
(See Publication No. 4).

[Problems to be Solved by the Invention] In the above-mentioned conventional technique, the retractable member is housed in the gate pillar when folded, but the contracted member becomes laterally overlapped, so that the width of the gate pillar is widened and the gate opening is narrowed. The disadvantage is that the expansion and contraction members become wide when the door is closed, causing the top and bottom to fall, impairing the function and appearance of the gate, and if the movable pillar does not have a roller that runs on the rail, the opening and closing operation will be hindered. However, there was a problem that it became complicated and costly.

The present invention has been made in consideration of such disadvantages of the related art.The purpose of the present invention is that the elastic member operates smoothly even if the movable pillar is not provided with rails or rollers, and the member does not move sideways when folded. The purpose of the present invention is to provide a telescopic door that can be easily installed in a narrow gatepost that does not become wide, has a good appearance, performs well as a gate, and is easy to install and install.

[Means for Solving the Problems] In order to achieve the above-mentioned object, the present invention employs the following technical means, namely, a fixed column having a concave groove having a U-shaped cross section and a concave groove having a U-shaped cross section. Opposing movable columns with
Between the fixed column and the movable column, a front stretchable body made up of a plurality of bending rods and a rear stretchable body made up of a plurality of bending rods are installed side by side, and the bending rods are bent upward and downward at the bent portions. It is pivotally attached so as to protrude, and the bending rods of the front and rear elastic bodies facing each other are pivotally attached at the intersection, and the end of the elastic body is pivotally attached to the end frame, and this end frame is movable with the fixed column. When mounted in the concave groove of the column, one end frame is made slidable in the concave groove, the other end frame is fixed in the concave groove, and the movable column is brought closer to the fixed column. It is an expandable retractable gate in which the expandable body is stored inside the fixed pillar and the movable pillar.

[Operation] To open the gate from the closed state, move the movable column toward the fixed column. Then, each of the bending rods constituting the elastic body is bent from the bent portion to narrow its angle, and the movable column moves toward the fixed column. Since the front and rear elastic bodies are pivotally attached at the intersection, they are interlocked with each other and the X-shaped spread is gradually narrowed. At the same time, one end frame of the expandable body slides inside the fixed column and the movable column, so even if the expandable body expands and contracts, the bent part does not project beyond a certain amount, so the contracted expandable body is fixed. It is completely housed inside the pillar, the movable pillar is in close contact with the fixed pillar, and the gate is fully open.

[Embodiment] In FIG. 1, 1 is a fixed column having a groove having a U-shaped cross section,
Reference numeral 2 denotes a movable column opposite to the fixed column, which has a U-shaped concave groove whose cross section is shallower than that of the fixed column. Since the gate shown in FIG. 1 is of a double-opening type, the movable pillar 2 is fitted in a butt shape at the center, and is opened by moving to the left and right. In the figure, the left side is in a closed state and the right side is in an open state. When fully closed, the engaging body 3 protruding on the side surface of the left movable column is fitted with the engagement hole 4 recessed in the right movable column, and both are in close contact. .

Reference numeral 5 is a front stretchable body made up of a plurality of (4 in the figure) bending rods, and 5a is a rear stretchable body made up of the same number of bending rods 6a arranged in parallel with the front stretchable bodies. The bending rod 6 of the front stretchable body 5 is a combination of two left and right belt-shaped rods a and b in an inverted V shape as shown in the third illustration, and the bending rod 6a of the rear stretchable body 5a is a belt-shaped rod a and b. The bending rods 6 and 6a are combined in a character shape, and the rod ends are pivotally attached by a shaft 8 at a central bending portion 7, and the front and rear elastic bodies 5 and 5a intersect each other at a crossing portion 9 thereof. Spacing
Pivot at pin 11 through 10. And front and rear stretchable body 5
5a are provided in two stages, upper and lower.

Both ends of the front and rear stretchable bodies 5 and 5a are end frames with a shallow U-shaped cross section.
It is rotatably pivotally mounted in the shaft 12 / 12a, and one of the end frames 12 is a fixed column in which the bent portion 7 of the bending rod is located at the uppermost and lowermost protruding end portions of the telescopic body. 1 and the movable column 2 are slidably mounted inside, and the other end frame 12a is fixed to the fixed column 1 and the movable column 2 by means such as screwing. That is, it is the upper front stretchable body 5 that projects to the uppermost side and the lower rear stretchable body 5a that projects to the lowermost side, so that the end frame 12 of these stretchable bodies fixes the movable column 2. When moving toward the pillar 1, the upper side descends and the lower side rises to smoothly contract the elastic body, and the upper elastic body 5 protrudes upward from the bending rod bending portion 7 and the lower rear elastic body. The downward projection of the bent rod bending portion 7 at the lower end of 5a is kept at a fixed position. The lower front stretchable body 5 and the upper rear stretchable body 5a pivotally attached to the fixed end frame 12a also contract smoothly with the sliding stretchable body, so that all stretchable bodies are It is stored inside the fixed column 1 and the movable column 2.

FIG. 5 shows another embodiment, which is different from the above-mentioned embodiment in that each of the bending rods 6 and 6a in the front and rear elastic bodies 5 and 5a is provided with three rods a.
-It is configured in Z shape by b and c. Also in this case
The rear stretchable bodies 5 and 5a are formed in a disoriented manner and are pivotally connected to each other at each intersection 9. In this embodiment, one of the bent portions 7 of the upper end bending rod of the upper front / rear elastic members 5, 5a protrudes to the uppermost side, so that the elastic member on the protruding side (the front elastic member on the left side in the figure, The end frame 12 with the rear stretchable body 5a on the right side is slidably mounted inside the fixed column 1 and the movable column 2, and the stretchable body on the side that does not project (the front stretchable body 5 on the right side, the rear stretchable side) Body 5a
The left end frame 12a is fixed to the inner side of the fixed column 1 and the movable column 2. Further, since one of the bent portions 7 of the lower end bending rods of the lower front and rear stretchable bodies 5 and 5a projects to the lowermost side, the projecting side stretchable body (in the figure, the front stretchable body 5 is the right rear stretchable body). The end frame 12 (5a on the left side) is slidably mounted inside the fixed column 1 and the movable column 2, and the elastic body on the side that does not project (front elastic body 5 in the figure).
