  However, a fixture in which a lower structure portion such as a leg portion and an upper structure portion such as a side plate and a top plate are separately formed and connected to each other may damage the design by exposing the fixture of the connection portion. There is.

  Then, an object of this invention is to provide the connection structure and fixture which can improve the designability of a lower structure part, an upper structure part, and a connection part.

  In order to achieve the above object, the connection structure according to the present invention includes a lower structure portion installed on an installation surface and an upper structure portion arranged above the lower structure portion, wherein the lower side The structure portion includes a lower connection portion that is overlapped with the upper structure portion in an overlapping direction that intersects the vertical direction, and the upper structure portion is overlapped with the lower connection portion in the overlap direction. One of the lower connection part and the upper connection part has a first fixing part on which an upward first fixing surface is formed, and the other is disposed on the first fixing part. A second fixed surface facing downward to the first fixed surface is formed and has a second fixed portion fixed to the first fixed portion, and either one of the lower connection portion and the upper connection portion is It has a hook part that is arranged at a position that overlaps the other and protrudes to the other side, , Characterized by having a hook engaging portion which is arranged on one and the overlapping position engages the hook portion and the upper connecting portion and the lower connecting portion is restricted from spaced said superposed direction.

  Further, the fixture according to the present invention is a fixture in which a lower structure portion installed on an installation surface and an upper structure portion arranged on the upper side of the lower structure portion are connected, and the lower structure portion is The upper structure portion has a lower connection portion that is overlapped in the overlapping direction intersecting the vertical direction, and the upper structure portion has an upper connection portion that is overlapped with the lower connection portion in the overlapping direction, One of the lower connection portion and the upper connection portion has a first fixing portion formed with an upward first fixing surface, and the other is disposed on the first fixing portion and the first fixing portion. A position where a downward second fixing surface facing the fixing surface is formed and a second fixing portion is fixed to the first fixing portion, and one of the lower connection portion and the upper connection portion overlaps the other Is disposed on the other side and protrudes to the other side, the other overlaps one Characterized in that it has a hook engaging portion and disposed location engages the hook portion and the upper connecting portion and the lower connecting portion is restricted from spaced said superposed direction.

In the present invention, the first fixing portion is fixed to the second fixing portion, and the hook portion is locked to the hook locking portion so that the lower connection portion and the upper connection portion are not separated in the overlapping direction. The lower structure portion and the upper structure portion can be connected to each other.
Since the hook part and the hook locking part are arranged at a position where the lower connection part and the upper connection part overlap, exposure to the outside can be suppressed. Moreover, since the 1st fixing | fixed part is fixed to the 2nd fixing | fixed part from the lower side, exposure to the upper direction or a side can be suppressed. By these things, the designability of the connection part of a lower structure part and an upper structure part can be improved.

The first fixing portion or the second fixing portion formed at the lower edge portion of the lower connection portion is disposed in the vicinity of the corner portion outside the L-shaped corner portion of the lower structure portion. For this reason, when fixing the first fixing portion to the second fixing portion, a fixing tool such as a screw or a tool such as a screwdriver does not interfere with the leg portion, and the operation is easy.

In the connection structure according to the present invention, the first fixing portion may be fixed to the second fixing portion from below with a fixing tool.
Since the first fixing portion is fixed to the second fixing portion from the lower side with a fixing tool, exposure of the first fixing portion and the fixing tool to the upper side and the side can be suppressed.

Further, in the connection structure according to the present invention, the hook portion has an upper piece extending upward on the distal end side in the protruding direction, the hook locking portion is opened downward, and the upper piece is inserted from the lower side. You may have an upper piece insertion recessed part.
Since the upper piece of the hook part is inserted into the upper piece insertion recess of the hook engaging part from below, the movement of the hook part in the horizontal direction is restricted, so that the hook part is prevented from being detached from the hook engaging part. Is done.

Further, in the connection structure according to the present invention, the lower connection portion is provided with the first fixing portion and the hook portion, and the hook portion is disposed above the first fixing portion, and the protrusion The second connecting portion and the hook engaging portion are provided on the upper connecting portion, and the hook engaging portion is connected to the distal end side of the hook portion in the protruding direction. You may latch from the upper side.
By setting it as such a structure, a 1st fixing | fixed part can be fixed to a 2nd fixing | fixed part in the stable state by which the hook part was latched by the hook latching | locking part from the upper side from the upper side.

Further, in the connection structure according to the present invention, the upper structure portion has a continuous portion that is continuously formed above the upper connection portion and does not overlap the lower connection portion in the overlapping direction, and the continuous portion The one side surface that is the lower connection portion side with respect to the upper connection portion in the stacking direction and the one surface in the stacking direction of the lower connection portion are arranged to be flush with each other. Also good.
The design property and the cleaning property can be improved by making the one side surface in the overlapping direction in the continuous portion and the one side surface in the overlapping direction in the lower connection portion flush with each other.

Moreover, in the fixture which concerns on this invention, the said upper structure part may have the top-plate part which is formed integrally with the said upper side connection part, and an upper surface becomes a work surface.
Since the upper structure portion has the top plate portion, the fixture can be used as a table, a work table, or a table on which objects are placed.

Moreover, in the fixture which concerns on this invention, the said upper structure part may have the information display part which is formed integrally with the said upper side connection part, and can display information.
Since the upper structure portion has the information display portion, the fixture can be used as a signboard.

Moreover, in the fixture which concerns on this invention, it may be arrange | positioned between the said lower side connection part and the said upper side connection part, and may have a wiring penetration part which can penetrate wiring.
By inserting the wiring through the wiring insertion portion, the exposure of the wiring can be suppressed, and the design of the fixture can be improved.
