BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a member connecting structure for connecting a pair of members diffractably.

[0002]

2. Description of the Related Art Conventionally, as a member connecting structure for connecting a first member and a second member diffractably, a connecting portion formed at an end of the first member and a connecting portion formed at a second member are formed. In order to keep the two members in a straight shape by connecting the connection parts together and connecting them using a connecting pin so that they can be diffracted, by moving the tube bodies mounted on the connection parts of both members onto the connection parts, A configuration has been proposed in which one member is provided with an engaging member biased by a spring, and the engaging member is engaged with an engaging portion provided in the other member.

[0003]

As described above, in the member connecting structure for connecting a pair of members diffractably, in order to keep both members in a straight shape, a pipe body is attached to both member connecting portions. However, with a structure in which an engaging member urged by a spring is provided, it is necessary to operate the pipe body and engaging members with the fingers at the connection site of both members, so the diff There is a risk of pinching your fingertips in the area.
In addition, structurally, the number of parts is large and complicated, and it is troublesome to handle, and there is also a possibility that a stable function cannot be expected over a long period of time because a failure or the like is likely to occur.

The present invention has been made in view of the above points, and an object thereof is to provide a member connecting structure in which the diffracting operation of a pair of members can be performed by one-touch operation, which is safe and convenient to handle.

[0005]

The gist of the present invention for achieving the above object is a member connection structure for connecting a first member and a second member in a diffractive manner. The connecting end is formed on the end of the member and the end of the second member, and both connecting parts are aligned, and the connecting pin provided on the first connecting part is inserted into the slot provided on the second connecting part. Both members are movably penetrated to connect both members, a support pin is provided in the first member connection portion at a predetermined distance from the connection pin, and a second member connection portion is provided corresponding to the support pin. The member connection structure is characterized in that a hook portion opened to one side is provided.

[0006]

With the support pin locked in the hook, the first member and the second member are maintained straight. After rotating one member to pull out the support pin from the hook part, pull both members in the separating direction to move the connecting pin into the long hole, and both members should be centered on the connecting pin. It becomes diffractable.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a plan view showing an essential part of the present invention, and FIG.
Is a front view.

In the figure, 1 is a first member, 2 is a second member, and connecting portions 3 and 4 are formed at the ends of both members 1 and 2, respectively. First member connecting portion 3 of the embodiment
Is composed of a pair of supporting pieces facing each other, and the second member connecting portion 4 is composed of a plate-shaped piece interposed between the pair of supporting pieces.

Reference numeral 5 denotes a connecting pin provided on the first member connecting portion 3, and the connecting pin 5 is movably penetrated into an elongated hole 6 provided on the second member connecting portion 4 so as to connect to the first member 1. Second member 2
The first member 1 and the second member 2 can be diffracted around the connection pin 5 as well.

Reference numeral 7 is a support pin provided near the base of the first member connecting portion 3 at a predetermined distance from the connecting pin 5.
Reference numeral 8 denotes a hook portion provided near the end of the second member connecting portion 4 corresponding to the support pin 7, which opens to one side and is supported by the diffraction of the first member 1 and the second member 2. The first member 1 and the second member 2 are maintained straight in a state in which the support pin 7 is locked to the hook portion 8.

Next, an application example of this invention will be described.

FIG. 5 is a plan view showing a case where the present invention is applied to a device for leaning long articles equipped on a fixed body such as a building wall.

The device A for leaning a long article comprises a plurality of support rods C which are horizontally projected from a vertical surface of a fixed body B at appropriate intervals, and between the support rods C, a long rod-like member is provided. The article D is made to lean against it.

The support rod C is composed of a first member 1 and a second member 2, the base of the first member 1 is fixed to a fixed body B, and the second member 2 is fixed to the first member 1. On the other hand, it is diffracted vertically. First member 1 and second member 2
In the state where it is in a straight shape horizontally, as shown by the solid line in FIG.
Locks and stabilizes.

In order to diffract the second member 2 from this state, hold the second member 2 at a proper position until the support pin 7 comes out from the hook portion 8 as shown by a chain line in FIG. 3 (a). After turning upward, the connecting pin 5 is moved into the elongated hole 6 by pulling up the second member 2 as shown by the chain line in FIG. 3 (b), and in this state, the second member 2 is pulled up. Is rotated downward, the second member connecting portion 4 is rotated away from the support pin 7, and the second member 2 is diffracted as shown by the solid line in FIG. The first member 1 hangs down via the.

In order to return the diffracted second member 2 to the straight position, the reverse order of the above operation is performed.

FIG. 4 is a partial cross-sectional view of the essential part showing another embodiment.

This embodiment shows an application example in which the support rod C is erected upright on the horizontal surface of the fixed body B. The lower end of the first member 1 is fixed to the fixed body B, and the second The member 2 is configured such that the member 2 is undulated with respect to the first member 1.

In this case, from the standpoint of raising the second member 2 to maintain the straightness with respect to the first member 1, the hook portion 8
A notched portion 9 is formed in the bottom of the notch toward the long hole 6 (upward), and the support pin 7 is locked in the notched portion 9 in a drop-like shape for stability.

[0021]

According to the present invention having the above structure, the following effects can be obtained.

(1) The diffracting operation of the pair of members is performed by holding the one member in the hand and rotating the member and slightly pulling both members in the separating direction. You can

(2) In the diffracting operation, since the position holding one member may be away from the connecting portion, there is no danger of the fingertip being caught by the connecting portion where the diffraction is inadvertently performed.

(3) Since the structure is simple and the number of parts can be reduced, it is not troublesome to handle, and it is possible to exhibit stable functions over a long period of time with less trouble and to be applied to the other side. Highly versatile.
