Description

[Detailed Description of the Invention] <Industrial Application Field> This invention is suitable for machining and mass producing 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 unsightly 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 wall of the horizontal member is provided with a series of fin rays whose tips protrude toward the hollow longitudinal member, and the contact wall of the hollow longitudinal member is provided with lateral slits corresponding to the thickness of the fin rays. In the fin rays of the horizontal member, a protruding piece that protrudes into the slit of the hollow longitudinal member is formed between the two grooves at a position where the hollow longitudinal member is connected; At the same time, the protruding piece of the fin strip is inserted into the hollow part through the slit of the hollow vertical member, and the both side walls of the hollow longitudinal member are inserted into the two strips on both sides of the protruding piece. It is characterized by inserting it into the groove so that the contact walls of both materials cross and come into contact with each other, and then deforming both side walls of the vertical member inward at the locking portion of the plunger piece to engage the locking portion. do.

<Example> In each of the illustrated examples, V indicates a hollow vertical member, and H indicates a horizontal member. Both members V and H are extruded from aluminum and manufactured to have a wall thickness of approximately 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 members. The thickness of this fin ray 3 should be approximately the same as the thickness of the cross member.

In this fin ray 3, two kerf grooves 4, 4 are formed from the tip toward the cross member at intervals that should connect the longitudinal members, and a projecting piece 5 is formed between the kerf grooves 4, 4 of the fin ray. do.

On the other hand, slits 6 in the vertical direction corresponding to the thickness of the fin rays 3 and into which the plunger pieces 5 penetrate are provided in the contact wall 1 of the vertical member V at a plurality of positions in the vertical direction connecting with the cross members.

Therefore, the protruding piece 5 of the fin ray 3 is inserted into the hollow part through the slit 6 of the vertical member, and both side walls v,
Contact walls 1,
Two comrades can be brought into contact orthogonally.

In the first embodiment shown in FIGS. 2 to 4, the two grooves 4, 4 of the fin ray 3 reach the outer surface of the contact wall 2 at the back. Further, both side walls v, v of the hollow vertical member are provided with a pair of projections 7, 7 facing each other in the longitudinal direction on the inner surface slightly away from the contact wall 1, and the slit 6 is provided with the projections 7, 7 on the contact wall 1. It is formed to match the opposing spacing between the strips 7, 7. The protruding piece 5 between the cut grooves 4, 4 is approximately T-shaped, and has locking portions 8 facing the contact wall 2 projecting from both left and right sides of the tip, and both locking portions 8, 8.
Is the width between them equal to the opposing distance between the protrusions 7, 7?
When the protruding piece 5 is inserted into the hollow part of the vertical member through the slit 6 as described above, the locking parts 8, 8 will close the distance between the protrusions 7, 7 as shown in FIG. just passing through.

Therefore, when both side walls v, v of the hollow vertical member are deformed inward at the protrusions 7, 7, as shown in FIG. The hollow vertical member V bites into and engages with the surface facing the contact wall 2 of the member H.
is connected to the cross member H so as not to separate from the cross member. Since the protruding pieces 5 protrude into the slits 6, the vertical members do not rattle vertically relative to the horizontal members, and the outer surfaces of both side walls v, v of the vertical members have kerfs 4 in front and behind the protrusions 7. 4, so there is no wobbling in the left and right directions.

The slit 6 formed in the contact wall 1 of the vertical member can be easily formed with a press, and since the slit is formed leaving the parts connected to both side walls v, v of the contact wall 1, the strength of the contact wall is not reduced. Less is.
Further, the protruding piece 5 can be easily machined with a press at the same time as the kerfs 4, 4 on both sides thereof, and furthermore, both side walls of the vertical member can be easily deformed inwardly with a press.

In the second embodiment shown in FIGS. 5 to 7, the hollow longitudinal member has a series of locking portions 8 on the inner surfaces of the side walls v, v that engage with the locking portions 8 of the approximately T-shaped projecting pieces 5 of the fin strips 3 of the transverse members. Opposed protrusions 7
7 in one piece.

In this embodiment, the left and right locking portions 8, 8 of the plunger piece 5
The width between them is approximately equal to the opposing spacing between the side walls v, v of the longitudinal member, and is wider than the opposing spacing between the protrusions 7, 7. For this purpose, a slit 6 with a width equal to the opposing spacing of both side walls is formed in the contact wall 1 of the vertical member by pressing,
Moreover, each notch 4 has a notch 9 facing the locking part 8,
9 will be provided.

Therefore, as mentioned above, the contact walls 1 and 2 of both materials V and H
When the vertical members are brought into contact with each other at right angles, the intermediate portions of both side walls v, v of the vertical member are pushed outward by the locking portions 8, 8, deform and bulge, and enter the notches 9, 9. Therefore, when this deformed part is pressed inward as shown by the arrow, the deformation is corrected, and the protrusions 7, 7 engage with the surface facing the contact wall 2 of the cross member H of the locking parts 8, 8, and the hollow vertical The material V is connected to the cross member so as not to separate from it, as in the first embodiment.

In the first embodiment, marks of inward deformation are produced on both side walls of the longitudinal member, but in this second embodiment, such marks are not produced, but instead, the notches 9 provided in the cut grooves 4 are visible. However, since each side wall v, v of the vertical member passes through the cut groove 4 before and after the notch 9, no rattling occurs in the left-right direction.

The third embodiment shown in FIGS. 8 and 9 is almost the same as the second embodiment described above, except that the kerf 4 of the fin ray 3,
4 ends before reaching the contact wall 2 of the horizontal member, and for this reason, a slit 6 is formed in the vertical member including the contact wall 1 and both side walls v, v.

In this case, the slit 6 is connected to the contact wall 1 and both side walls v,
The strength of the hollow vertical member is as follows:
The advantage is that slits can be formed in a large number of vertical members at once by lining up a plurality of hollow vertical members and sawing them, although the slits are slightly smaller than when the slits are formed by pressing as in the first and second embodiments. There is.

In the three embodiments described above, the opposing protrusions 7, 7 are integrally provided on the inner surfaces of both side walls of the hollow vertical member, and the connection is made using these protrusions 7, 7.
The connection can be made without providing a protrusion as in the fourth embodiment shown in the figure.

The fin rays 3 of the horizontal member are T-shaped between the grooves 4, 4, and the width between the left and right locking parts 8, 8 is the opposite side wall v of the vertical member.
It has protruding pieces 5 that are equal to or slightly shorter than the interval v. Therefore, in the contact wall 1 of the vertical member, a slit 6 which is approximately equal to the spacing between the side walls v, v is press-formed, and at the same time, a slit 6 is formed in both side walls v, v.
Press a T-shaped cut 10 at the same level as . This cut 10 faces the contact wall 2 of the cross member of the locking portions 8, 8 when the plunge piece 5 is inserted into the hollow part of the vertical member through the slit 6 and the contact walls 1, 2 are brought into contact orthogonally. Formed in a part located next to the surface.

Therefore, with the horizontal member H and the vertical member V in contact with the contact walls 1 and 2 and perpendicular to each other, the cuts 10 and 10 in each side wall are made.
When 10 is pressed inward with a press, an inwardly deformed piece 10' is generated, and the tip of this deformed piece touches each locking part 8.
The connection is made by engaging the surface facing the cross member.

In this embodiment, each cut 10 is formed in a T-shape to produce inwardly deformed pieces 10' vertically.
The shape of 0 may be, for example, an L-shape, and the inwardly deformed pieces may be produced either at the top or bottom.

In the first to fourth embodiments described so far, the locking portion 8,
8 was formed on both left sides of the protruding piece 5, but the 13th to 1st
As in the fifth embodiment shown in FIG. 5, the projecting piece may be made to protrude on the upper or lower surface and face the contact wall 2 of the cross member.

In this fifth embodiment, when pressing the cut grooves 4, 4 on the fin ray 3 and the protruding piece 5 between them, L-shaped cuts are formed on both sides of the protruding piece, and the area surrounded by these cuts is diagonally cut. By bending upward or downward (obliquely upward in the figure), locking parts 8, 8 are formed whose free ends face the contact wall 2 of the cross member.

Therefore, in the contact wall 1 of the vertical member, a slit 6 which is thicker than the thickness of the fin ray 3 and through which the above-mentioned locking parts 8, 8 can also be passed is press-formed, and in addition, a slit 6 is formed in the contact wall 1 of the vertical member.
A T-shaped or L-shaped cut 10 similar to that in the fourth embodiment is pressed at a position opposite to the free end of the locking part, so that the contact walls 1 and 2 of the vertical member and the horizontal member are brought into contact at right angles. After this, the cuts 10 are pressed inward with a press to produce inwardly deformed pieces 10', which can be engaged with the free ends of each locking part 8 and connected in the same way.

In this embodiment, the thickness of the slit 6 is greater than the thickness of the fin ray 3, but since the inwardly deformed piece 10' contacts the upper and lower surfaces of the protruding piece 5, the vertical member V is larger than the horizontal member H.
There is no wobbling in the vertical direction.

In this way, the locking part 8 protruding from the upper surface or lower surface of the plunger piece 5 and facing the contact wall 2 of the cross member is the 16th,
As shown in Figure 17 and the examples in Figures 18 and 19, the fin rays 3
It can also be formed by integrally thickening a ridge 3' having a serrated cross section along the leading edge of the cross member H.

In the embodiment shown in FIGS. 16 and 17, when the ridge 3' is integrally formed on the upper or lower surface of the fin ray 3,
The embodiment shown in FIG. 19 is one in which the ridges 3' are integrally formed on both the upper and lower surfaces of the fin ray 3.

In both of these embodiments, the fin rays 3 are provided with both side walls v of the vertical member,
By pressing the two grooves 4, 4 through which v passes,
A projecting piece 5 having a locking portion 8 formed by the ridge 3' can be formed.

Therefore, in the embodiment shown in FIGS. 16 and 17, the inwardly deforming piece 1 engages with the part of the locking part 8 facing the contact wall 2, and also contacts the upper surface or the lower surface of the plunger piece 5.
In addition, in the embodiment shown in FIGS. 18 and 19, the cut 10 where 0' is formed is engaged with the portion of the upper and lower locking portions 8, 8 facing the contact wall 2, and the upper and lower surfaces of the plunger piece 5 are Cuts 10, 10, in which the inwardly deformed pieces 10', 10' contact each other, are formed by press working on the side walls v, v of the vertical members, respectively, and the portions sandwiched between the cuts are pressed inward by a press. , can be connected in the same way as in the fifth embodiment.

In each of the illustrated embodiments, 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 may also protrude from the upper or lower edge of the contact wall 2. .

Further, the cross-sectional shape of the vertical member is not limited to the rectangular shape shown in the figure, and the contact wall 1 may be curved convexly or concavely, or, for example, as shown in FIGS. The wings W may protrude outward from the wall or both side walls.

<Effects of the Invention> According to the present invention, the horizontal slits 6 in the contact wall 1 of the vertical member can be easily formed by sawing or press working, and two slits 6 are formed in the fin rays 3 of the contact wall 2 of the horizontal member. Processing for forming the protruding piece 5 having the cut grooves 4, 4 and the locking part 8 facing the contact wall 2 between them can also be easily carried out using a press.

Further, after the contact walls of both the vertical and horizontal members are crossed and brought into contact with each other, both side walls of the vertical member can be deformed inwardly by press working.

Then, the inwardly deformed portions of both side walls of the vertical member engage with the locking portions of the protruding pieces of the horizontal member, preventing the vertical member from moving away from the horizontal member, and at the same time, the vertical member is prevented from moving away from the horizontal member. Because the protruding pieces protrude into the slits, the vertical members cannot move vertically relative to the horizontal members, and the edges of the fin rays 3 adjacent to the kerf prevent the vertical members from moving laterally as well. .

Thus, 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.
