Description

[Detailed Description of the Invention] <Industrial Application Field> This invention is suitable for mass production by machining gates, fences, building window lattices, etc. in which multiple vertical lattices are attached to multiple horizontal members. This invention relates to a method for cross-connecting suitable hollow vertical members (vertical lattice) and horizontal members (horizontal bars).

<Prior Art> Conventionally, the connection between the vertical lattice and the horizontal beams is usually done by welding if the two materials are steel pipes, or by screws or metal or plastic rivets if they are made of aluminum or stainless steel pipes.

<Problems to be solved by the invention> In the case of welding, welding marks are visible and
Rust occurs in a relatively short period of time. Furthermore, in the case of using screws or rivets, it is necessary to drill a hole and pass the screw or rivet through the hole, so it is not suitable for mechanized processing and assembly for mass production.

<Means for Solving the Problems> Accordingly, the present invention provides: A method for cross-connecting hollow vertical members and horizontal members, in which the hollow vertical members and the horizontal members are brought into contact with each other at their contact walls, and are fixed in that state; The contact walls of the cross members are provided with a series of fin rays whose tips project toward the hollow longitudinal members, and these fin rays are provided with a series of fin rays having the same width as the hollow longitudinal members and having a width similar to that of the hollow longitudinal members. a notch that reaches the contact wall of the hollow longitudinal member, and a protruding piece that protrudes toward the hollow longitudinal member within the cutout; the hollow longitudinal member has a transverse slit that receives the protruding piece in the contact wall; is provided with opposing openings at both ends of the fin rays adjacent to the notch; at the same time as the hollow vertical member is fitted into the notch in the fin ray, the protruding piece is inserted into the hollow portion through the slit in the hollow vertical member. Then, in the hollow part of the vertical member, the protruding piece is bent along the inner surface of the contact wall of the vertical member, and both tips of the fin rays adjacent to the notch are bent. It is characterized in that it is deformed and inserted into openings in both side walls of the vertical member.

<Example> In the illustrated row, V indicates a hollow vertical member, and H indicates a horizontal member. Both members V and H are manufactured by extrusion molding of aluminum to a thickness of about 0.8 to 1.5 mm. The hollow longitudinal members may be pipes, which may be made of stainless steel, and the cross members may be hollow pipes or C-section members.

Both materials are in contact at contact walls 1 and 2, respectively, and intersect at right angles here. The cross member H integrally has a series of fin rays 3 which project from the contact wall 2 with their tips toward the longitudinal member. The thickness of this fin ray 3 should be approximately the same as the thickness of the cross member.

This fin ray 3 is formed with a notch 4 having the same width as the vertical member and into which the outer surfaces of both side walls v, v of the vertical member can slide, from the tip to the outer surface of the contact wall of the horizontal member, and inside the notch 4. A protruding piece 5 is provided which protrudes from the outer surface of the contact wall toward the vertical member.

On the other hand, the contact wall 1 of the vertical member V has lateral slits at a plurality of positions in the vertical direction connecting with the horizontal member, corresponding to the thickness of the fin rays 3, and through which the protruding piece 5 can penetrate into the hollow interior. 6 will be provided.

Therefore, the protruding piece 5 of the fin ray 3 is inserted into the hollow part of the vertical member through the slit 6, and both side walls v,
The contact walls 1 and 2 of the vertical members V and the horizontal members H can be brought into contact with each other orthogonally by sliding the contact walls 1 and 2 of the vertical member V and the horizontal member H by slidingly contacting the cutout portion 4 of the fin ray 3.

Openings 7, 7 having a thickness slightly smaller than the thickness of the fin rays are formed in both side walls v, v of the hollow vertical member at positions corresponding to the tips of the fin rays 3 in sliding contact.

Therefore, as described above, the vertical member V and the horizontal member H are brought into contact with each other at the contact walls 1 and 2, and the contact wall 1 of the vertical member is cut by striking the projecting piece 5 with a tool from the end open to the hollow part of the vertical member.
The protruding portions 8 into the openings 7 are formed by bending the fin rays 3 upward or downward along the inner surface of the fin rays 3 and pinching and crushing the tips of the fin rays 3 adjacent to the notch 4 with a tool.

As a result, the contact wall 1 of the vertical member is prevented from separating from the contact wall 2 of the cross member by the bent protruding piece 5 and the protruding portions 8, 8 which are deformed and plunged into the openings 7, 7, and , the vertical movement of the vertical member relative to the horizontal member is prevented by the protruding piece 5 passing through the slit 6 of the contact wall 1 and the projecting portions 8, 8 into the openings 7, 7, and furthermore, the horizontal movement of the vertical member relative to the horizontal member is prevented. This is prevented by the fin rays in contact with the side walls of the longitudinal members, ensuring that the two members V and H are connected in perpendicular contact.

In this embodiment, the deformed entry portion 8 into the openings 7,
The fin rays 3 for forming the fins 8 are integrally provided with a thickened protrusion 3' along the tip when forming the cross member H, but this protrusion 3' can be omitted.

Further, the fin rays 3 provided on the contact wall 2 of the cross member protrude from the middle of the height of the contact wall 2, but of course they can also be made to protrude from the upper or lower edge of the contact wall 2.

Furthermore, the cross-sectional shape of the vertical member is not limited to the rectangular shape shown, and the contact wall 1 may be curved convexly or concavely, and furthermore, the cross-sectional shape of the vertical member may be curved convexly or concavely. Wings W may extend over the top (Fig. 3).

<Effects of the Invention> According to the present invention, the lateral slits 6 in the contact wall 1 of the vertical member and the openings 7 in both side walls can be easily formed by press working, and the fin rays of the contact wall 2 of the horizontal member can be easily formed. Processing for forming the notch 4 and the protruding piece 5 on the plate 3 can be easily performed using a press.

Also, after the contact walls of both the vertical and horizontal members are crossed and brought into contact, the protruding piece 5 is bent from the end of the vertical member within the hollow part thereof, and the tip of the fin ray adjacent to the notch is crushed. It is also possible to easily form the protruding portion 8 by press working.

The contact wall 1 of the vertical member is prevented from separating from the contact wall 2 of the cross member by the bent protruding piece 5 and the protruding portions 8, 8 which are deformed and plunged into the openings 7, 7. The vertical movement with respect to the cross member is caused by the slit 6 of the contact wall 1.
The projecting piece 5 passing through the openings 7 and the projecting portions 8, 8 that similarly enter the openings 7, 7 prevent this, and furthermore, the fin rays in contact with both side walls of the vertical member prevent the horizontal movement of the vertical member relative to the horizontal member.
Both materials V and H are securely connected in perpendicular contact. Therefore, the present invention has an excellent feature of increasing the productivity of gates, fences, window lattices, etc. in which a large number of vertical lattices are attached to the horizontal rails, and enables mass production.
