 The present invention mainly relates to a bar connecting fitting used in the construction of a bed frame for hydroponics.

[0002]

[Prior Art]

 This type of structure requires a large number of metal fittings for connecting columns and beams, or beams to each other, and in addition to the simplicity of the structure, it is also necessary to have easy connection, disassembly, and adjustment. To be done. In addition, the above-mentioned columns such as columns and beams must be connected and held with considerable strength while being maintained at a certain connection angle, for example, a right angle.

[0003]

[Problems to be solved by the device]

 Especially when the bar is a square or channel type cross section, if the accuracy of the connecting surface with the connecting metal fitting is not sufficient, the structure will be distorted and a sufficient friction contact surface cannot be secured. It is difficult to secure the bond strength during the period.

[0004]

[The purpose of the device]

 The present invention has been made based on the above circumstances, and the connecting metal fitting main body can be constructed by simple processing such as bending from a plate-like body and press punching. The purpose of the present invention is to provide a rod connecting fitting that secures the strength, can accurately maintain the joint angle between the rods, and can be easily joined, disassembled, and adjusted.

[0005]

[Means for Solving the Problems]

 Therefore, in the present invention, as clearly shown in the illustrated embodiment, the rods (1 and 2) having a square or channel cross section are adjacent to each other and are joined at right angles to each other. When inserting one bar (1) into the metal fitting, the connecting metal fitting main body (made of a plate-shaped body having an inverted U-shaped cross section, which has a pair of left and right supporting wall surface portions (3A, 3A) that support both side surfaces of the bar material (1). In 3), the rectangular window holes (5, 5) into which the other bar (2) is inserted so that the upper surface is in contact with the ceiling wall surface (3B) of the coupling fitting body (3) are provided with the supporting wall surface portion (3A, 3A), the clamp member (4) for pushing up the lower surface of the former bar (1) and abutting the upper surface thereof against the lower surface of the latter bar (2) is formed on the handle portion (4A). ) And the clamp part (4B) connected to it, are bent and formed in an L shape. The clamp portion (4B) has a protruding portion (4C) which is eccentric to the lateral side of the central axis thereof, and the bearing hole (6) is formed so as to face the supporting wall surface portions (3A, 3A). , 7) so that they can be inserted and removed freely.

[0006]

[Action]

 Therefore, one bar (1) is sandwiched between both support wall surfaces (3A, 3A) of the fitting main body, and the position / posture is regulated, and the other bar (2) is the fitting main body (3). ) Is inserted into the rectangular window holes (5, 5) while being supported by the ceiling wall surface (3B) of FIG. Your posture is regulated. Moreover, the clamp member (4) can have a sufficient surface contact area with respect to the coupling die body (3), exhibiting a sufficient effect for frictional coupling, and achieving a desired coupling. Can maintain strength. Further, there is an advantage that the coupling, disassembly and adjustment can be easily performed only by operating the clamp member (4).

【Example】

 Hereinafter, an embodiment of the present invention will be specifically described with reference to the drawings. In the figure, reference numerals 1 and 2 are bars to be joined, and in this embodiment, they have a square cross section. The joining fitting of the present invention for joining the rods 1 and 2 is composed of a joining fitting body 3 which is simply formed by bending and punching a plate-like body, and a clamping member 4 made of a round bar. There is.

The connecting metal fitting body 3 has an inverted U-shaped cross section having a pair of left and right supporting wall surface portions 3A and 3A that support both side surfaces of the rod material 1 when the rod material 1 is inserted. 3, rectangular window holes 5 and 5 into which the other bar 2 is inserted so that the upper surface is in contact with the ceiling wall surface 3B are formed at the support wall surface portions 3A and 3A. Further, the clamp member 4 is bent and formed in an L shape so as to form a grip portion 4A and a clamp portion 4B connected to the grip portion 4A, and the clamp portion 4B is a protrusion portion which is eccentric to the side from the central axis thereof. 4C, and is configured so that it can be removably inserted into the bearing holes 6 and 7 that are opened facing the support wall surface portion 3B. Then, the lower surface of the former bar 1 is pushed up by the above-mentioned protrusion 4C and its upper surface is brought into contact with the lower surface of the latter bar 2. In this embodiment, the pressing surface of the projection 4C is formed flat, and the bearing hole 6 on the first insertion side of the clamp 4B is formed in an oval shape. Further, in this embodiment, the grip 3 is provided on the coupling fitting body 3 so as to prevent the clamp portion 4B from rotating while the lower surface of the bar 1 is pushed up by the protrusion 4C of the clamp member 4. A stopper portion 8 that supports the portion 4A is provided.

The connecting fitting having such a configuration is used as follows. That is, first, the bar 2 is inserted into the rectangular window holes 5 and 5, and the upper surface of the bar 2 is brought into contact with the ceiling surface 3 B of the connecting fitting body 3. Next, the rod 1 is inserted between the support wall surfaces 3A and 3A of the connecting fitting body 3 so as to intersect the rod 2 at a right angle, and the upper surface of the rod 1 is attached to the rod 2. Touch the bottom surface. In this state, the crank portion 4B of the crank member 4 is inserted into the bearing holes 6 and 7, the handle portion 4A is operated, and the clamp portion 4B is rotated until it comes into contact with the stopper portion 8. As a result, the projection 4C pushes up the lower surface of the bar 1 and the elasticity of the clamp 4B presses the bar 1 against the lower surface of the bar 2. As a result, both rods 1 and 2 are eventually pressed against the ceiling surface of the clamp member 4 and held and fixed to the connecting fitting body 1 by frictional contact.

Incidentally, if necessary, a mat-shaped friction member is sandwiched between the ceiling surface and the second rod member 2, between the first and second rod members, and the like. You may reinforce the holding power. Further, in this embodiment, a material having a square cross section is shown as the bar material, but a material having a channel cross section may be adopted.
