[0002]

2. Description of the Related Art Conventionally, an expandable gate of this type is known, for example, from Japanese Utility Model Publication No. 4-44798. This expandable door is composed of a pair of vertical frames arranged parallel to each other in the prospective direction, a connecting frame spanning between upper ends of the pair of vertical frames, an outer peripheral surface of the pair of vertical frames and an outer periphery of the connecting frame. It is composed of a decorative frame that covers the surface and a telescopic link slidably attached to the inside of a pair of vertical frames. Telescopic links are attached to the vertical frame at two locations, one on the top and one on the bottom.
One part is slidably mounted on the vertical frame and one part is rotatably mounted on the vertical frame. That is, the expandable link is provided with sliders at both outer ends of the intersecting shafts of the respective X links, and correspondingly, the sliders slide on the vertical frame in a retaining state. A swallow groove is formed so as to be freely engaged. Then, of the upper and lower two cross shafts attached to the vertical frame, the slider provided on one cross shaft slidably engages with the vertical frame (swallow groove) as it is, and the other cross shaft is attached to the other cross shaft. The slider provided is screwed from the outside of the vertical frame and is rotatably attached to the vertical frame.

When assembling this telescopic gate, the telescopic link is first erected with a jig or the like, and the vertical frame is inserted into this, and the slider is inserted into the swallow groove of the vertical frame.
Insert them one by one and assemble them. Next, the pair of vertical frames facing each other are aligned and the connecting frame is attached thereto. Finally, the decorative frame is attached to the vertical frame and the connecting frame.

[0004]

As described above, in the conventional method of assembling the expandable gate, since the lattice frame is composed of three members, that is, the vertical frame, the connecting frame and the decorative frame, the number of assembling steps increases and the assembly is troublesome. was there. Further, when the vertical frame is incorporated (inserted) in the telescopic link, it is necessary to align each slider with each time, which makes the work extremely complicated and time-consuming.

An object of the present invention is to provide a method of assembling an expandable gate which can be easily assembled in a short time and an expandable gate to which this assembly method can be applied.

[0006]

Assembling an expandable gate that has an expandable link that is vertically slidable with respect to a pair of vertical frames by a slider of the expandable link that is engaged with the dovetail groove of each vertical frame in a retaining state. In the method, the telescopic link is sandwiched by a pair of vertical frames, and at least one slider is press-fitted into the swallowing groove.

According to this structure, since the expansion link is assembled between the pair of vertical frames by relatively directly press-fitting the slider from the side into the swallowing groove of the vertical frame, It is not necessary to lift the frame, and the swallowing groove can be aligned with each slider at the same time. When only one of the sliders is press-fitted, it is preferable to attach a vertical frame to the other slider in advance and use this as a receiving member for press-fitting.

In the method for assembling the expansion / contraction gate according to claim 1,
A connecting frame is attached between the upper ends of the pair of vertical frames, and the upper ends of the pair of vertical frames are integrally connected by a decorative frame arranged along the connecting frame, and the decorative frame is swallowed. In the state where the other part is cut out except the part corresponding to the back wall of the groove, the connecting frame and the telescopic link are held in predetermined positions, and the pair of vertical frames and the decorative frame are linear. It is preferable that the slider is pressed against the connecting frame and bent to press-fit the slider.

According to this structure, as in the first aspect, since the slider is directly press-fitted into the swallowing groove of the vertical frame from the side, it is not necessary to lift the vertical frame, and the swallowing groove is not required. It becomes easy to position the slider on the slider. In addition, since a pair of vertical frame and decorative frame that are integrated and linear are applied to the connecting frame and then bent, the connecting frame and the telescopic link to the vertical frame can be simply assembled. It can be done at the same time in one operation. In addition, the connecting frame can be fixedly and immovably incorporated in the arch frame regardless of product variations, and the pair of vertical frames and the decorative frame can be designed to have a sense of unity.

In the method for assembling the expansion / contraction gate according to claim 1 or 2, at least one of the opening edge of each vertical frame forming the opening of the swallowing groove and the slider has an inclined surface for guiding press-fitting. It is preferably formed.

According to this structure, the guide action of the inclined surface allows the positional alignment between the opening edge of each vertical frame and the slider.
It becomes easier and the press-fitting can be performed smoothly. It should be noted that this inclined surface is preferably formed by bending both opening edge portions inward in each vertical frame, and in the case of a telescopic link, the slider has a tapered taper shape. It is preferable to form it.

The telescopic gate according to claim 4 comprises a pair of vertical frames arranged in parallel with each other in the prospective direction and a telescopic link incorporated inside the pair of vertical frames, and each vertical frame is swallowed. This is an expandable gate that has an expandable link slideably engaged with a pair of vertical frames in a vertical direction by a slider of an expandable link engaged with the groove in a retaining state, and forms an opening for a swallowing groove. At least one of the opening edge of at least one of the vertical frames and the corresponding slider is formed with an inclined surface for guiding the press-fitting of the slider into the opening edge. .

According to this structure, the slanted surface enables the telescopic link to be directly attached to the vertical frame by press fitting, and the ease of assembly can be improved without impairing the function of the telescopic link.
