SUMMARY OF THE INVENTION It is an object of the present invention to improve the efficiency of the work of attaching the horizontal member to the vertical member, to facilitate the work, to have a simple structure, and to firmly connect the vertical member and the horizontal member. It is an object of the present invention to provide a coupling device that can perform the following.

[0005]

The coupling device comprises a vertical member, a horizontal member, a male member and a female member. The male member and the female member can be formed by cutting an extruded shape made of a metal such as aluminum or a hard and tough synthetic resin into a predetermined length. As the vertical member and the horizontal member to be connected, for example, there may be a long member such as a cubic and a blind member, or both a block-like short member.

The male member has a bolt insertion hole, and is attached to the vertical member with a bolt and a nut that penetrate the vertical member and penetrate the vertical member in a direction along the horizontal axis of the horizontal member. The female member is attached to the horizontal member and has a fitting hole in the horizontal axis direction of the horizontal member. The male member attached to the vertical member is fitted into the insertion hole of the female member attached to the horizontal member, and the horizontal member is joined to the vertical member.

Since the male member and the female member are mounted by fitting, the male member and the female member are engaged with each other to temporarily fix the male member and the female member when the horizontal member is attached to the vertical member, so that a substantially completed state is obtained. it can. In the case where the cubic and the blind are joined, the male member and the female member can be engaged with each other to be in a temporary fixing state. Both hands are free to work, and work efficiency is high.

[0008] When the horizontal member is connected to both sides of the vertical member, male members can be arranged on both sides of the vertical member, and can be attached with one bolt and nut. Bolts and nuts may be commercially available bolts and do not require special processing. The male member attached to the vertical member is attached with bolts and nuts that penetrate the vertical member and penetrate the vertical member in the direction along the horizontal axis of the horizontal member, so that thick bolts and long bolts can be used. Thus, the male member can be securely connected to the vertical member without play, and can be firmly connected.

The male members mounted on both sides of the vertical member are each fitted with a female member that has been attached in a blind manner by fitting the male member into its fitting hole. Since the load by the horizontal member acts uniformly on both sides of the bolt penetrating the vertical member, a biased force (rotation moment) that deforms the mounting surface of the male member in the vertical member does not act. For this reason, the connection between the vertical member and the horizontal member is stabilized. Since each male member is fixed to both sides of the vertical member at once with one bolt and nut, work efficiency is improved.

When the horizontal member is connected to only one side of the vertical member, a male member is arranged on one side of the vertical member and attached with one bolt and nut.

In some cases, the male member has a circular cross section and the female member has a circular cross section that matches the male member. In this configuration, only the male member is fitted to the female member, and there is no play between the male member and the female member fitting hole.
The positioning of the horizontal member with respect to the vertical member can be determined at one time. However, since rotation is possible, the posture of the horizontal member in the rotation direction with respect to the vertical member can be easily adjusted. Therefore, after fitting at an angle convenient for the operation with respect to rotation, it is possible to return to a correct posture and fix it.

In some cases, the male member has a circular cross section and the female member has an oval cross section. In this configuration,
It is possible to adjust the position of the female member relative to the male member in the oval range, to absorb a shift in the mounting position due to a processing error between the vertical member and the horizontal member, and to facilitate the work.

Note that the cross-sectional shape of the male member and the cross-sectional shape of the fitting hole of the female member are basically not limited to a circle as long as they can be fitted, and one is a polygon and the other is a circle. Sometimes it is shaped. Further, the vertical and horizontal mean the relative relationship between the two members, and do not mean the posture that the two members take. Further, the vertical member and the horizontal member may not only have a relationship in which the end surface of the horizontal member is abutted against the vertical member and be joined, but also a relationship in which the horizontal member intersects the vertical member without abutting.
