FIG. 4 is a side view around the lattice frame 12. The lattice frame 12 has an arch frame 31 formed in a substantially inverted "U" shape.
An upper frame (connecting frame) 32 attached to the inside of the upper end of the arch frame 31 and a lower frame 3 attached to the lower end of the arch frame 31
3 is comprised. The arch frame 31 includes a pair of vertical frame portions 34 and 34 disposed in parallel with each other, and a pair of vertical frame portions 3.
The upper and lower frames 34, 34 are formed integrally with the decorative frame 35 disposed along the upper frame 32 between the upper ends of the pair of vertical frames 34, 34, and the telescopic link 13 is disposed inside the pair of vertical frames 34, 34. ing.
In this case, the arch frame 31 is formed by bending a shape member (grid frame constituent material) having a “C” -shaped cross section in which a portion corresponding to the decorative frame portion 35 is cut out along the upper surface of the upper frame 32.
Is formed.

Accordingly, each of the vertical frame portions 34 has a "C" -shaped cross section of the raw material, and the space inside the cross section is a swallow groove 36 for attaching the telescopic link 13. Further, a step (upper end of the vertical frame) 37 is formed between each vertical frame 34 and the decorative frame 35, and this step 37 is
It serves as a portion for locking the upper frame 32 as described later.
On the other hand, the decorative frame portion 35 is cut out leaving the back wall of the “C” -shaped cross section (actually, the side wall is also slightly left), so that it can be easily bent. I have. Further, thereby, the arch frame 31 can be bent, and the outer peripheral surface thereof is a continuous surface, so that the arch frame 31 is finished in a neat design with a sense of unity.

The upper portion of the upper frame 32 has a curved shape, and the upper surface thereof is engaged with the decorative frame portion 35, and both lower end portions are fitted into the swallowing groove 36 of the vertical frame portion 34. It is attached to the arch frame 31 in such a way as to match. That is, the upper frame 32 is pressed from above by the decorative frame portion 35 and pressed from below by the step portion 37,
It is attached so as to be included in the upper end of the arch frame 31. Similarly, the lower frame 33 has both ends at the vertical frame portion 3.

Attached to.

The telescopic link 13 provided inside the arch frame 31 is connected to both vertical frame portions 34, 34 of the arch frame 31 via a shaft provided at the intersection of each link 21 constituting the telescopic link 13. Installed. This telescopic link 13
Then, the intersection of each link 21 is 3
Two points occur between the points and the middle of the adjacent lattice frames 12 and 12 (see FIG. 1). Of the three intersections, the first shaft 22 provided at the upper two intersections supports the two intersecting links 21 so as to be rotatable relative to each other, and slides at both ends thereof. The two vertical frame parts 34,
34 are slidably engaged with the swallowing grooves 36, 36, respectively. In addition, a second shaft 2 provided at one intersection on the lower side
4 supports the two links 21 and 21 so as to be rotatable with respect to each other, and uses the screws 25 and 25 whose both ends are screwed from the outside of the vertical frames 34 and 34 to form the two vertical frames 34 and 34.
Respectively. Furthermore, the adjacent grid frame 1
A third shaft 26 provided at two intersections between the two 2 and 12 supports the two intersecting links 21 and 21 so as to be rotatable relative to each other. And between these two links 21 and 21 and between the link 21 and the vertical frame part 34,
The spacers 27 are interposed so as to be inserted into the extension members 4 and 26 to prevent the telescopic link 13 from rattling in the expected direction.

As shown in FIG. 5, each of the above-mentioned sliders 23 has a spindle-like neck portion 23a attached to the end face of the first shaft 22, and a head rotatably attached to the neck portion 23a. And a portion 23b. Head part 2
3b is formed in a tapered tapered shape. When the slider 23 is press-fitted into a swallow groove 36 of a vertical frame portion 34 described later, the tapered inclined surface 23c is
It guides the press-fitting of b and facilitates the positioning of both. That is, the diameter of the distal end of the head portion 23b is smaller and the diameter of the proximal end thereof is larger than the dimension between the opening edges 34a, 34a of the vertical frame portion 34 constituting the opening 36a of the swallowing groove 36. Therefore, when the vertical frame portion 34 comes into contact with the slider 23, the tip of the slider 23 fits into the opening 36a, and when the vertical frame portion 34 is further pushed in, the tapered shape of the head portion 23b ( The inclined surface 23c) presses and spreads the opening edges 34a, 34a, and the head 23b is completely fitted into the swallowing groove 36 up to the base end.

Here, a method of assembling the telescopic gate of the embodiment will be described. As shown in FIG. 6, an arch frame 31 in which a pair of vertical frame portions 34, 34 and a decorative frame portion 35 are straight before bending is prepared, and at the same time, the upper frame 32 and the elastic link 13 are cured. It is set at a predetermined height position with a tool. Next, the decorative frame portion 35 of the arch frame 31 is
2, the arch frame 31 is bent along the upper frame 32 (FIG. 2A). Further, the bending is continued, and the telescopic link 13 is formed from both sides by the pair of vertical frame portions 34, 34.
, And the slider 23 is relatively press-fitted into the swallow groove 36. After that, the lower frame is assembled (FIG. 9B). After all the grid frames 12 and the end members 11 are assembled in this manner, small parts such as casters 14 and locks 15 are assembled to complete the operation.

The one vertical frame 3 of the arch frame 31 is previously set.
4 is attached to one of the sliders 23 of the telescopic link 13 from the fore edge side, and in this state, the decorative frame portion 3 of the arch frame 31 is mounted.
5 may be applied to the upper surface of the upper frame 32, the arch frame 31 may be bent along the upper frame 32, and the other vertical frame portion 34 may be pressed into the other slider 23.

As described above, according to the method of assembling the telescopic gate of this embodiment, the slider 23 of the telescopic link 13 is formed in a tapered shape, and the slider 23 is pressed into the swallow groove 36. In this way, the telescopic link 13 and the vertical frame portion 34 are assembled to each other, so that the assembly work including positioning can be performed easily and instantly. Moreover, the pair of vertical frame portions 34, 34 can be assembled to the telescopic link 13 at the same time. Therefore, the telescopic gate 1 can be assembled in a very short time and easily.

Next, another embodiment of the engagement portion between the slider 23 and the vertical frame portion 34 will be described with reference to FIG.
In this embodiment, the head portion 23b of the slider 23 has a simple roller shape.
The opening edges 34a, 34a of the vertical frame portion 34 are bent inward and inclined. That is, the width of the opening edge portions 34a, 34a at the intermediate position between the inclined surfaces 34b, 34b is substantially the diameter of the head portion 23b. Thus, when the vertical frame portion 34 comes into contact with the slider 23, the tip of the slider 23 is fitted into the opening 36a by about half, and when the vertical frame portion 34 is further pressed, the head portion 2
3b presses and spreads the opening edges 34a, 34a via the inclined surface 34b and completely fits into the base end.

According to this configuration, similarly to the above-described embodiment, the positioning between the slider 23 and the swallow groove 36 is facilitated by the guide of the inclined surface 34b, and the press-fitting is facilitated.

The lattice frame 12 in each of the above embodiments is
Although a special structure using the arch frame 31 is used to emphasize the appearance design, the present invention can be realized by setting the shape of the slider 23 and the shape of both opening edges 34a of the vertical frame 34 as described above. The method of assembling the telescopic gate described above can be applied to a lattice frame having a general structure.

FIG. 8 shows a lattice frame having such a general structure applied to the present invention. The lattice frame 12 is composed of an upper frame 51, a lower frame 52, and both vertical frames 53, 53. It is configured. The head of the slider 23 is formed in a tapered shape. In this case as well, the telescopic link 13 is sandwiched between the vertical frames 53, 53 and assembled by press-fitting as shown in FIG. Then, both vertical frames 53,
The upper frame 51 and the lower frame 52 are assembled to 53 (FIG. 9B). Therefore, the telescopic gate 1 can be assembled in a very short time and easily.

The slider 23 may be formed in a tapered shape, and inclined surfaces may be provided at both opening edges 34a of the vertical frame portion 34.
