However, according to the conventional vertical bar attachment device as described above, for example, when a playful child tries to climb up the gate while holding the vertical bar due to some circumstances. As described above, there is a problem that when a vertical pulling force is applied to the vertical bar, the vertical bar bends and comes out of the support hole.

In order to prevent the vertical cross-bar from coming off, it is conceivable to increase the wall thickness so that it will not bend, but this is not suitable for reducing the weight of the gate and inevitably increases the cost. In addition, the applicant also tried to penetrate each vertical bar with a connecting rod so as to prevent the vertical bar from being pulled out so as to be hooked inside the upper and lower frames. Since the communication rod is passed through the hole of No. 3, which requires extremely difficult work, it was not easy to assemble.

The present invention has been made in view of the above circumstances.
In the lattice type gate made of extruded aluminum, the communication holes for preventing the vertical bars from penetrating through each end of the vertical bars prevent the vertical bars from falling out or bending, and it is easy to penetrate the connecting rod. It is an object of the present invention to provide a vertical crossbar mounting device for a lattice type gate.

In order to achieve the above-mentioned object, the present invention incorporates a large number of vertical rails in a frame of left and right vertical rails, an upper rail and a lower rail, and each vertical rail is mounted on the upper rail. In a lattice type gate that is supported by penetrating a frame and a lower frame, the upper frame and the lower frame are fitted with a frame body in which dovetail grooves are formed on the surfaces facing each other and the dovetail groove cannot be escaped. It is configured by a combination with an attachment, and each attachment is formed in a channel shape in which it is opened on the side facing the bottom wall of the dovetail groove, and a support hole through which a vertical bar passes is formed in this attachment. Installation of vertical bars, characterized in that through holes for communication rods are formed at both upper and lower ends of each vertical bar, and the communication rods that have passed through the through holes of each vertical bar are hooked on the inner surface of the attachment. Configured the device.

[0008]

[Operation] When assembling the lattice type gate, when the end of the vertical bar is inserted into each supporting hole of the attachment before the attachment of the attachment and the attachment of the attachment and the attachment to the upper and lower stiles, the rear opening side of the attachment is Since the communication rod can be surely passed through the through hole at the end of each vertical bar while clearly confirming with the eyes, the work can be easily performed. Then, by combining the frame body with the hook, and connecting the left and right vertical frames while stretching so as to expand between the upper and lower frames that are combined, the tensioned installation state so that the vertical bars do not bend Is obtained.
