Description of the Related Art Conventionally, as a connecting device for a movable partition wall of this type, a column interposed between panel units and an engaging claw projecting from a side end surface of the panel unit are formed in the column. The panel unit is connected to each other by engaging with the hook hole, and the adjacent panel unit is formed of a band-shaped flat plate connecting bridging the upper surface or the lower surface adjacent to each other across the column. Is connected to the panel unit by bolting the panel unit to the upper surface of the panel unit and fixing the panel unit to the upper end of the column with a bolt. In this case, when connecting the panel units in a straight line, a connecting member that fits the connecting shape, such as a straight connecting member and a T-shaped connecting member at a portion that intersects in a T-shape. Is consolidated.

[0003]

Generally, such a movable partition wall is used for connecting a plurality of panel units to partition, for example, a corridor portion and other portions, and the like. Often, the connection shape is changed to change the arrangement. However, if the connection fitting is formed in a specific shape according to the connection shape of the panel unit as in the above configuration, for example, if a connection that has been connected in a straight line is to be reconnected in a T-shape, a T-shaped connection is required. Is required. Therefore, the user must always keep several kinds of connecting brackets at hand in consideration of such a change in arrangement, or purchase them each time, and secure a place for storage. In addition, in order to purchase a new product, the shape and number of necessary products must be inspected according to the arrangement, and in any case, labor is required.

A second metal fitting 10 having a tapered surface 10c facing the portion 10b and a head 10d provided at the other end.
A through hole 9c is formed in the center of the first metal fitting 9,
The first metal fitting 9 is fixed to the column 1 by inserting the bolt 11 into the through hole 9c and screwing the bolt 11 to the embedded nut 1c of the column 1. The length of the second metal fitting 10 excluding the body part 10b and the external thread part 10a is the tapered surface 10 of the head part 10d.
c is slightly shorter than the outer dimension in the longitudinal direction of the panel-side metal fitting 9 so that c presses the vertical piece 6a of the panel-side metal fitting 6 at the time of connection.

Next, the connection of the two panel units 5 will be described. It is assumed that the panel lower bracket 12 has been attached to the panel unit 5 first.

In this embodiment, the panel unit 5
Are connected in two directions orthogonal to each other, and the positioning pins 1d are inserted into the holes 2g with the strips 2a and 2b of the first connection fitting 2 facing the direction in which the panel unit 5 is arranged. It is temporarily attached to the lower end surface 1a. Similarly,
The second connection fitting 3 is superimposed on the first connection fitting 2, and in this state, the hexagonal bolt 4 is inserted into the central through holes 2d, 3d of the first and second connection fittings 2, 3, and then screwed into the embedding nut 1c. Then, the first and second connection fittings 2 and 3 are completely fixed.
With the column 1 to which the first and second connection fittings 2 and 3 are fixed as described above in the center, one panel unit 5 is connected to the first

The column-side connecting member 7 assembled as described above is arranged on the upper surface of the column 1. In this case, the column-side connecting member 7 is a head 10 d of the second metal fitting 10.
Is engaged with the substantially U-shaped notch 6b provided on the vertical piece 6a of the panel-side metal fitting 6, so that the first metal fitting 9 floats above the bottom surface of the cutout groove 5a and stops. Therefore, the first metal fitting 9 is pressed downward by applying pressure, and the bolt 11 is further screwed in so that the body 10b of the second metal fitting 10 is fitted to the lower end of the substantially U-shaped notch 6b. I do. In this manner, the body 10b is substantially U-shaped notch 6b.
Into the tapered surface 10 of the second metal fitting 10 at that time.
c pushes the vertical pieces 6 a of the panel-side fitting 6 toward the center of the column 1. Therefore, the respective panel units 5 can be attracted to each other in the direction of the column 1 by the column-side connecting member 7, and adhere to the column 1 by making use of the elastic properties of the tree, and the two panel units 5 5 is connected to the connecting portion without forming a gap. After the connection in this manner, covers 15 and 16 are fitted to the upper portion of the column 1 and the cutout grooves 5a of the panel unit 5 to cover the connection portion.

Next, another embodiment will be described with reference to FIGS. In this embodiment, the panel units 5 are connected in a cross shape in a plan view.

As shown in FIG. 6, when the panel units 5 are connected in four directions, the strips 2a, 2b, 3a, 3b of the first and second connection fittings 2, 3 must also face the four directions. Must. Therefore, the first and second
As shown in FIG. 7, in the combination of the connection fittings 2 and 3, the central through holes 2d and 3d are made to coincide with each other, and the intersection 2c and the intersection 3c are overlapped. In this way, when the plane shape is viewed around the center through-hole 2d, it becomes a cross-shaped bracket that is deviated and orthogonal to one side. In this state, the pillar 1 is fixed to the lower end surface 1a of the pillar 1 with a hexagonal bolt 4 to complete the pillar 1 with a connection fitting for connecting the four panel units 5. The connection is the same as in the above embodiment, and a detailed description is omitted. In this embodiment, each of the panel connecting pins 2e, 2f, 3g, 3h is individually inserted into the panel unit 5.

FIG. 8 shows a panel unit 5.
First and second connection fittings 2 and 3 when connecting in a T-shape
It is a top view which shows superposition of. That is, in this case, only one of the strips 2a and 2b of the first connection fitting 2 is overlapped with one of the strips 3a and 3b of the second connection fitting 3. By superimposing in this manner, the first and second connecting fittings 2 and 3 substantially overlap the band-shaped portion 2b and the band-shaped portion 3a with the band-shaped portion 2a.
The T-shaped connection fitting on which a and 3b are arranged.

As described above, the panel units 5 can be connected in three different shapes only by changing the manner of overlapping the first connection fittings 2 and the second connection fittings 3. Even in the case of a small number of connections in two directions, by stacking the respective connection fittings 2 and 3, it is possible to use only one of them and store it in the same place without storing the other.

The present invention is not limited to the embodiment described above. In the above embodiment, the lower end surface 1 of the column 1
Although the first and second connecting fittings 2 and 3 are described as being fixed to a, the upper end face 1b may be used.

In addition, the configuration of each section is not limited to the illustrated example, and various modifications can be made without departing from the spirit of the present invention.
