[Summary of the present invention]
A fence connecting device of the present invention is a connecting device for connecting fences having furring strips formed of hollow members, and comprises a main body portion that can be slidably inserted into an end of the furring strip, and the connecting member. A feed shaft for moving in the sliding direction has engaging portions detachably formed on the main body at a plurality of locations along the sliding direction.
According to the fence connecting device of the present invention, the connecting device can be slid in the longitudinal direction of the furring strip by inserting the feed shaft member through the long hole formed in the furring strip and engaging with the engaging portion. The furring edges of adjacent fences can be connected to each other by causing the connector to protrude from the end of the furring strip by sliding the feed shaft member, while the connector can be moved to the edge of the furring strip by sliding the feed shaft member. By pulling it into the part, the furring strips of the fence can be disconnected from each other, and only the fence to be replaced can be easily removed.
Furthermore, since the engaging portions are detachably attached to the feed shaft at a plurality of locations along the sliding direction, the coupler is slid by sliding the feed shaft, and then the feed shaft is engaged. It is possible to disengage from the part, engage with the engaging part again at a different position in the sliding direction, and further slide the connector by sliding the feed shaft. By repeating the sliding movement in this manner, the sliding movement distance of the coupler can be extended without being restricted by the length dimension of the long hole formed in the furring strip. Therefore, the length dimension of the long hole formed in the furring strip can be reduced, and the appearance design of the fence can be maintained.

In the fence connector of the present invention, the feed shaft is a feed screw, the engagement portion has a pair of engagement pieces forming a groove along the slide direction, and the pair of engagement The piece may be disposed so as to be screwed onto the feed screw that is screwed into the groove.
According to such a configuration, the feed screw can be screwed into any position of the groove along the sliding direction of the coupler to engage with the pair of engaging pieces.

In the fence connector of the present invention, the engaging portion may have a plurality of holes arranged at equal intervals along the sliding direction.
According to such a configuration, since the plurality of holes are arranged at intervals in the sliding direction, it is possible to easily grasp the movement distance of the coupler with respect to the furring strip in the forward sliding movement described above.

In the fence connector of the present invention, the body portion has a pair of side piece portions along the sliding direction, and the engaging portion is formed on one or both of the pair of side piece portions. may
In the case where the engaging portions are formed on both of the pair of side pieces, the coupler can be slid by engaging the feed shaft with the pair of engaging portions. A moment is less likely to occur in the coupler than in the case where it is formed only on one of the side pieces, and the risk of an increase in slide resistance due to this moment can be reduced.
When the engaging portion is formed on only one of the pair of side pieces, compared to the case where the engaging portion is formed on both sides, only the portion of the furrings that is aligned with one of the side pieces is elongated. It is possible to eliminate the need to form an elongated hole in the portion that is fitted to the other side piece. In addition, since only one feed shaft may be used, it is possible to simplify the operation of sliding the connecting member using the feed shaft.

The fence of the present invention comprises: a plurality of fences each having a fence body; furring strips formed by hollow members attached to the fence bodies; and the connector of the present invention for connecting the plurality of fences. At least one end in the longitudinal direction of the furring strip is formed with an elongated hole extending in the sliding direction of the connector so that the feed shaft can be inserted therethrough.
According to the fence of the present invention, it is possible to configure a fence capable of exhibiting the same effects as those of the connector of the present invention described above.
