Description

The present invention relates to a corner joint structure that can be used in an assembled partition, booth, and the like.

As a conventional corner joining structure (ATM booth pillar structure), there is one described in Patent Document 1. According to this, the pillar is formed in a cross beam shape (a cross shape), and the ribs protruding from the square columnar pillar body are provided with screw holes and grooves, so that the panel can be mounted in up to four directions of the pillar. In addition, it was possible to attach a decorative cover in the direction where the panel is not required.

JP 2001-132145 A

However, in the above corner joint structure, the decorative cover is attached in the direction where the panel is not necessary.Therefore, when attaching only in two or three directions of the pillar, you must prepare a different decorative cover to hide the ribs. Therefore, it is difficult to flexibly deal with the usage.

In view of the above circumstances, the present invention provides a corner joining structure which can be flexibly dealt with according to the usage mode.

According to the invention of claim 1, a base member installed on the installation surface, and two pillar members standing upright from the base member,
The base member has a fixed mounting portion to which the one pillar member is mounted, and a movable mounting portion to which the other pillar member is mounted,
The pillar member is formed in a square tubular shape, and a panel member can be attached to an outer peripheral surface of the pillar member,
The movable mounting portion is formed so that the mounting position of the other pillar member is movable with respect to one of the pillar members,
A sandwiching attachment mode in which the panel member is attached by being sandwiched between the outer peripheral surface of the one pillar member and the outer peripheral surface of the other pillar member,
An outer peripheral surface mounting mode in which the panel member is mounted only by the outer peripheral surface of the pillar member in a mode other than the sandwiching mounting mode,
Can be taken.

According to this, by adopting a configuration in which the holding attachment mode can be adopted, the panel member is attached only by the outer peripheral surface of the pillar member that has been conventionally used, for example, the outer peripheral surface attachment that decorates only the outer surface side of the exhibition booth. In addition to the mode, it is possible to adopt a mounting mode in which only the inner surface side is decorated, or both the inner and outer surface sides are decorated, so that it is possible to flexibly deal with the usage mode.

The pillar member is attached to the base member via an L-shaped metal fitting,
The L-shaped member has an upper attachment portion attached to the pillar member and a lower attachment portion attached to the base member,
The movable mounting portion of the base member penetrates from the upper surface to the lower surface, the upper mounting portion is inserted, and the movable elongated hole that allows the upper mounting portion to move, and the movable elongated hole are provided continuously. And a guide groove formed as a bottomed groove extending from the lower surface to the upper surface so that the lower mounting portion can slide.

According to this, since the position of the pillar member can be moved by moving the position of the L-shaped metal fitting by the movable mounting portion of the base member, it is possible to easily adopt the sandwiching attachment mode.

In addition, a top member that is bridged between the upper ends of the one pillar member and the other pillar member is provided,
The top member has a fixed locking portion and a movable locking portion movable with respect to the fixed locking portion.

According to this, the joining state can be stabilized by restricting the movement of the upper ends of the one column member and the other column member by the top member. Furthermore, since the movable locking portion makes it possible to cope with the movement of the mounting position of the other pillar member on the base member, the assembling work can be facilitated.

Further, the pillar member has a slider guide portion on which a slider of a gap adjusting member for adjusting the length between the pillar members of the different corner joint structures can slide, and the slider guide portion is arranged. The panel member is attached to the outer peripheral surface other than the outer surface.

According to this, it can be made suitable when a corner joining structure is formed using the space adjusting member.
