Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a grid body that allows easy installation of a grid.

Conventionally, in the case of lattice bodies such as fences, handrails, lattice doors, transoms, etc., a large number of lattices are installed vertically or horizontally between upper and lower crosspieces or between left and right crosspieces. Both ends of these grids were fixed to the upper and lower or left and right crosspieces using fixing parts such as screws. Therefore, when assembling this type of grid, it is necessary to prepare fixed parts such as screws for each grid, and the fixed parts must be tightened one by one using a tightening tool such as a screwdriver. The work of installing the grid was complicated and required a lot of effort. Furthermore, according to fixed parts such as screws,
If the tightening was insufficient, the fastenings would gradually loosen over the years, causing the grate to come off.

This invention was made in view of the above drawbacks,
Cut grooves are formed at both ends of each grid, and the cut grooves are
Fixing parts such as screws can be used by fitting into the wedge pieces formed at the center of the opposing faces of the crosspieces and securing both ends of the lattice with locking protrusions formed on both sides of the wedge pieces. To provide a lattice body which enables the installation of a lattice without any trouble, makes the installation work of the lattice extremely easy, and maintains a strong attached state for a long period of time.

Hereinafter, one embodiment of the present invention will be described based on the drawings. Fig. 1 is a partially omitted front view of the so-called senbon lattice transom using the present invention, Fig. 2 is an enlarged perspective view of the fixed part, Fig. 3 is an enlarged cross-sectional view taken along the line A-A in Fig. 1, and Fig. 4 is an enlarged perspective view of the fixed part. The figure is an enlarged cross-sectional view taken along the line B--B of FIG. 1, and FIG. 5 is an enlarged cross-sectional view of a fixed portion of the second embodiment.

In the drawings, reference numeral 1 denotes a senbon lattice transom, in which a large number of lattices 20 are installed in parallel and at equal intervals between upper and lower crosspieces 10. The upper and lower crosspieces 10 each have a wedge piece 11 formed in the central longitudinal direction of their opposing surfaces, and locking protrusions 15 lower than the wedge pieces 11 are formed in parallel on both sides of the wedge piece 11 in the longitudinal direction. Wedge piece 11
The gripping portion 12 is provided with a tip inclined in a chevron shape and with serrations (sawtooth grooves) carved on both sides of the upper half. Furthermore, guide portions 16 that are inclined toward the wedge piece 11 are provided at the tips of the locking protrusions 15 on both sides. The crosspiece 10 is thus
It has a shape in which the wedge pieces 11 and the locking protrusions 15 are formed linearly in the longitudinal direction, and is formed as an extruded material of aluminum or aluminum alloy. 13
This is a non-slip part provided in the upper half of the wedge piece 11 at the same spacing as the installation interval of the grid 20. After forming the crosspiece 10 as described above, the engaging part 12 of the upper half of the wedge piece is cut and raised. Moreover, it is formed by being bent.

The lattice 20 is formed into a hollow prism with a rectangular cross section, and its width is equal to or slightly wider than the interval between the locking protrusions 15 formed on the crosspiece 10. Then, cut grooves 21 are formed on both side surfaces at the same height as the wedge piece 11 of the crosspiece 10 and the same thickness as the engaging part 12 of the wedge piece 11 or slightly narrower. It has been done. Further, in the hollow part of the lattice 20, locking protrusions 22 for engaging with the non-slip parts 13 of the wedge pieces 11 to prevent lateral movement of the lattice 20 are protruded at the same intervals as the width of the non-slip parts 13. It is set up.

Lattice body 1 having crosspieces 10 and lattice 20 as described above
The assembly is done as follows.

The wedge piece 11 of the crosspiece 10 and the cut groove 21 at one end of the lattice 20 are positioned so as to face each other so that the anti-slip part 13 of the wedge piece 11 and the locking protrusion 22 of the lattice 20 cannot be engaged. Thereafter, the cut grooves 21 are fitted into the wedge pieces 11, and the ends of the grid are clamped to the locking protrusions 15 to fix the grid 20 to the crosspiece 10. At this time, the ends of the lattice 20 are fitted into the cut grooves 21 while being slightly expanded at the tip chevrons of the wedge pieces 11, so that the end surfaces of the lattice 20 come into contact with the guide portions 16 of the locking protrusions 15. When it touches the guide part 16
The grooves 21 are fitted while being slightly closed by the inclined surfaces. At the same time, the end of the grid is guided by the guide portion 16 and press-fitted between the locking protrusions 15. Therefore,
Engagement portion 1 between cut groove 21 of lattice 20 and wedge piece 11
2 are tightly engaged with each other, the ends of the lattice 20 are clamped to the locking protrusions 15, and the ends of the lattice 20 are firmly fixed to the crosspieces 10. When fixed, the non-slip portion 13 of the wedge piece 11 and the locking protrusion 22 inside the lattice are also engaged, so the lattice 20 will not move laterally. In this way, when one end of each lattice 20 is fixed to one of the upper and lower crosspieces 10, the other end of each lattice 20 is fixed to the other crosspiece 10 in the same manner, and the lattice 20 are attached to the upper and lower crosspieces 10 to assemble the lattice body.

Note that the thickness of the upper half of the wedge piece 11 is made larger than the width of the cut groove 21, or the thickness of the upper half of the wedge piece 11 is
If the width of the latching protrusion 15 is larger than the interval between the locking protrusions 15, the engaging part 1 is attached to the upper half of the wedge piece 11.
2, the lattice 20 is firmly fixed to the crosspiece 10. Further, if the width of the anti-slip portion 13 of the wedge piece 11 is made equal to or slightly narrower than the inner width of the hollow portion of the lattice 20, the locking protrusion 22 can be omitted.

In the second embodiment shown in FIG. 5, the locking protrusion 15 of the crosspiece 10 is formed in a hook shape with the locking portion 17 facing toward the wedge piece 11 side, and the locking protrusion 15 is formed on the end side of the lattice 20. A cutout groove 23 that engages with the stopper portion 17 is provided to securely attach the crosspiece 10 and the grid 20. In the case of this embodiment, once the grid 20 is fixed to the crosspiece 10, it hardly comes off.
Enables reliable installation.

As described above, according to the present invention, the wedge pieces and the locking protrusions are formed on the crosspiece, the cut grooves of the lattice are fitted into the wedge pieces, and the ends of the lattice are clamped by the locking protrusions. This makes it possible to securely attach the grid to the crosspieces by simply using the same method, eliminating the need for fixing each of the many grids using fixing parts such as screws, which was done when assembling a conventional grid. The installation work to the crosspiece can be done extremely easily and quickly.

Moreover, since the grid is fixed by the wedge pieces and the locking protrusions, it can be reliably and firmly attached to the crosspiece.

Further, since the grid has the non-slip portions of the wedge pieces located inside and fitted into the wedge pieces, it is possible to reliably prevent the grid from moving laterally along the wedge pieces.
