Description

[Detailed description of the invention] This invention relates to a fence consisting of upper and lower cross members and a large number of lattices.

Conventionally, this type of fence has a complicated structure for both the horizontal members and the lattice, and screws and other connectors are used to connect the horizontal members and the lattice, so screw holes and screw through holes are provided and tools such as screwdrivers are used. This requires a lot of time and effort, and has the drawback of increasing the price of the fence in terms of both manufacturing and installation.

In view of the above points, this invention has a simple structure for both the cross members and the lattice, and is easy to manufacture.
It is an object of the present invention to provide a fence that does not require fixing tools such as screws, is easy to assemble, and can be installed at low cost.

Next, one embodiment of this invention will be described based on the drawings.

Reference numerals 1, 2, and 3 are an upper cross member, a lower cross member, and a lattice, respectively, which constitute the fence according to this invention.

The upper horizontal member 1 is a main body 1 formed in the shape of a long rectangular tube.
a, and a protruding edge 1b that protrudes downward along the entire length on the lower surface thereof.

The lower cross member 2 also integrally includes a main body 2a formed in the shape of a long rectangular tube, and a projecting edge 2b projecting upward along the entire length on the upper surface of the main body 2a. In a preferred embodiment, the upper cross member 1 and the lower cross member 2 have the same shape and are arranged vertically symmetrically.

And, on the projecting edges 1b and 2b of each cross member 1 and 2,
As clearly shown in FIG. 2, a pair of vertical slits 1c, 1d, 2c, 2d are opened vertically opposite each other at a predetermined interval in the longitudinal direction of the cross members, that is, at the grid attachment positions. The protrusions 1e and 2e are formed by the protruding edges left between each pair of vertical slits. In addition, fitting recesses 1f, 1g, 2f, and 2g are formed by enlarging the middle portion of the vertical slit toward the fitting protrusions 1e and 2e.

A plurality of grids 3 are used. The lattice is formed into an almost rectangular tube shape, and on both left and right sides in the middle of the front and back direction,
It has a fitting part that protrudes over the entire length of the grid.
This fitting part includes a pair of vertical walls 3a, 3b that protrude in parallel with an interval approximately equal to the wall thickness of the projecting edges 1b, 2b of each of the horizontal members, and an intermediate portion that connects the vertical walls at an intermediate portion in the projecting direction. The wall 3c forms an H-shaped cross section, and grooves are formed inside and outside the intermediate wall.

The inner groove opens into the hollow part of the lattice, and the outer groove opens to the outside of the lattice.

In this way, to assemble the fence from the cross members 1 and 2 and the lattice 3, insert the fitting protrusion 1e of the upper cross member 1 into the hollow part of the lattice 3, and insert both ends of the fitting protrusion 1e into the fitting part of the lattice. At the same time, the intermediate wall 3c of the lattice 3 is fitted into the vertical slits 1c and 1d of the upper horizontal member, and the end of the protruding edge 1b is fitted into the groove on the outside of the lattice. Then, the root portions of one or both of the vertical walls 3a and 3b of the lattice are pushed into the fitting recesses 1f and 1g on both sides of the fitting protrusion 1e of the upper horizontal member and deformed 3d in the longitudinal direction and right angle direction of the lattice. The upper cross member 1 and the lattice 3 are connected by preventing the movement of the upper cross member 1 and the lattice 3.

The other grids are connected at their upper ends to the upper crosspieces in the same way.

Next, apply the lower horizontal member 2 to the other end of each grid 3, insert the fitting projections 2e of the lower horizontal member into the hollow part of the grid, and insert both ends of the fitting projections into the grooves inside the grid. At the same time, a pair of intermediate walls 3e of each lattice are fitted into each pair of vertical slits 2c, 2d of the lower cross member, and a projecting edge 2b is fitted into a groove on the outside of the lattice.
Either or both of the vertical walls 3a and 3b are deformed 3d into the fitting recesses 2f and 2g on both sides of the fitting protrusion 2e.
and connect the lattice and lower crosspiece.

The connection form between the vertical walls 3a, 3b and the intermediate wall 3c of the lattice 3 can be U-shaped or H-shaped, but by making the cross section H-shaped, fitting protrusions 1e, 2e and projecting edges can be formed in the inner and outer grooves. Since both 1b and 2b are fitted and clamped, there is an advantage that the connection strength between the lattice and the upper and lower cross members is significantly increased.

In addition, fitting recesses 1 are provided on both sides of the fitting protrusions 1e and 2e.
By providing f, 1g, 2f, 2g, the deformed portion 3d of the vertical walls 3a, 3b of the lattice becomes the intermediate wall 3 of the lattice.
Since the projecting edges of the cross members are fitted into the grooves on the outside of the grid, the slits and fitting recesses are not exposed to the outside due to the deformed connection.

In FIGS. 1 and 2, 4 is a column, 5 is an upper support, 6 is a lower support, and 7 and 8 are joints. Numeral 9 is a screw for fixing the support 5 to the support column 4, and numerals 10 and 11 are screws for connecting the cross members 1 and 2 to the joints 7 and 8.

As mentioned above, according to this invention, the cross members have a simple structure with projecting edges, and the lattice has a fitting part with an H-shaped cross section consisting of a pair of vertical walls and an intermediate wall on both left and right sides. Since it has a simple structure, it can be manufactured at low cost. In addition, the intermediate wall of each lattice is fitted into the vertical slit formed at the lattice attachment position of each projecting edge, and the fitting protrusion of the horizontal member is fitted into the lattice, and the root portion of the vertical wall is pushed and deformed to connect. Therefore, fixing tools such as screws and rivets are not required, and the fence can be easily assembled using only tools such as punches. Therefore, since no fixing tools are used, work efficiency is improved.

In addition, the fitting portion of the lattice is formed into a substantially H-shaped cross section, the fitting protrusions and ridges of the cross members are fitted into the inner and outer grooves, and the root portions of the vertical walls of the fitting portion of the lattice are fitted with the fitting protrusions. Since the slits and the fitting recesses are pressed into the fitting recesses on both sides and are connected by deformation, the slits and the fitting recesses are not exposed to the outside due to deformation during processing of the vertical wall or deformation when an external force is applied.
