Like the vertical lattice 4, the horizontal lattice 7 is made of an extruded aluminum or aluminum alloy material, and cutouts 8 that fit with the notches 5 of the vertical lattice 4 are formed on the surface at positions intersecting with the vertical lattice 4. Note that 9 and 10 are reinforcing pieces protruding from both side walls 4a and 7a inside the lattice of the vertical lattice 4 and the horizontal lattice 7, respectively.

The fastening tool 11 in FIGS. 4 and 5 is a first embodiment of the fastening tool of the present invention, and is a single elastic plate made of metal or synthetic resin, with a trapezoidal fastening in the center. A piece 12 is provided, and a pair of left and right locking side pieces 13 are provided on both sides of the bottom thereof, slanting outward. In this fastening tool 11, a trapezoidal fastening piece 1
A pair of protrusions provided on both sides of the locking side piece 13 are elastically locked while being pressed against the locking protrusion 6 so as to be expandable and contractible. The projecting piece is elastically locked while being pressed against the inner surface wall 7b of the upper wall of the horizontal lattice 7 in a freely expandable and contractable manner, and the locking side piece 13 is pressed against the inner surface wall 7b of the horizontal lattice 7 in a freely expandable and contractable manner. The vertical lattice 4 and the horizontal lattice 7 are fixed by being elastically locked in this state. In the case of this fastening tool 11, the locking piece 12
Since it is formed in a trapezoidal shape, the strength of the entire locking piece is high, and the grid can be firmly fixed without wobbling. Also, since it is made of a single plate,
Fasteners can be manufactured easily.

The fastening tool 14 in FIG. 6 is a second embodiment of the fastening tool of the present invention, and is an elastic plate made of metal material or synthetic resin material, with the center shaped like a shape and a part of both sides thereof being removed. A locking piece 15 is provided as a cut-out piece (protrusion) 15a facing downward, and a pair of left and right locking side pieces 16 are provided on both sides of the locking piece 15 so as to be inclined outward. In this fastening tool 14, the locking piece 15
The head of the vertical lattice 4 comes into contact with the surface inner wall 4b, and the cut-and-raised piece 15a is elastically locked in a state where it is pressed against the locking protrusion 6 so that it can expand and contract, and the locking side piece 16 The vertical lattice 4 and the horizontal lattice 7 are fixed by elastically locking the projecting pieces on both sides while being pressed against the surface inner wall 7b of the horizontal lattice 7 in a freely expandable and contractable manner. In the case of this fastening tool 14, the overall shape of the fastening tool is simple, and the cut-and-raised pieces 15a can be processed by simple steps such as punching, making it easy to manufacture the fastening tool as a whole. Furthermore, the locking pieces 15 are highly elastic and do not cause rattling between the grids.

The fastening tool 17 in FIG. 7 is a third embodiment of the fastening tool of the present invention, and consists of two parallel elastic plates each having a copper part (protruding part) 18a bent outward at the tip. A pair of left and right locking side pieces 1 are formed by standing upright to form a locking piece 18, and the lower end of the locking piece 18 is fixed to the center and both sides thereof are inclined outward.
9 is formed. The first and second elastic plates
Similar to the fasteners 11 and 14 in the embodiment, metal or synthetic resin materials are used. In this fastening tool 17, the hook portion 18a at the tip of the locking piece elastically locks while being pressed against the locking protrusion 6 so that it can expand and contract, and the protrusions on both sides of the locking side piece 19 expand and contract. The vertical lattice 4 and the horizontal lattice 7 are fixed by being elastically locked while being freely pressed against the surface inner wall 7b of the horizontal lattice 7. In the case of this fastening tool 17, since the fastening piece 18 is formed in the shape of a hook by two elastic plates, the fastening piece 18 is rich in elasticity, and latticework can be performed extremely easily and reliably, resulting in improved workability.

In each of the fasteners 11, 14, and 17 in the first to third embodiments, the width of the elastic plate is slightly shorter than the width of the notch in the longitudinal direction of the notch 5 of the vertical lattice 4. . Moreover, 20 is a screw for fixing the grid body 3 to the frame frame 1.

The lattice fittings constructed in this manner are assembled as follows. First, each notch 8 of the horizontal lattice 7
Attach the fastening tools 11, 14, and 17 to the fastening tool 1.
The locking pieces 12, 15, 18 of 1, 14, 17 protrude from the notch 8, and the locking side pieces 13, 16, 1
9 is locked to the surface inner wall 7b of the horizontal lattice 7. Next, fasteners 11, 14, 1 protruding from the cutouts 5 of the vertical grid 4 from the cutouts 8 of the horizontal grid 7 are attached.
It fits into the locking pieces 12, 15, and 18 of No.7. At this time, the locking protrusions 6 of the vertical lattice 4 are
The ends of the locking pieces 12, 15, 18 are passed through in a compressed state against the elasticity of the locking pieces 12, 15, 18, and are fitted together. After the locking pieces 12, 15, and 18 are fitted into the vertical lattice 4, the ends of the locking pieces are elastically and firmly locked with the locking projections 6. This work is performed using multiple vertical and horizontal grids 4 and 7.
This is done at each of the notches 5 and 8 to form a lattice structure 3 in an intersecting manner. Next, the lattice body 3 is fitted into the frame 1 and fixed with screws 20, thereby constructing a fitting with a lattice.

In addition, although the above-mentioned example explained the fitting with the lattice in which the glass was fitted, the present invention can also be applied to the fitting with the lattice in which the glass is not fitted. Further, the present invention can be applied even if the configurations of the vertical lattice and the horizontal lattice are reversed. Further, in the above embodiment, the locking piece and the locking side piece of the fastening tool are formed symmetrically, but it is also possible to have some difference in shape, size, etc.

As described above, according to the present invention, the fasteners for fixing the vertical lattice and the horizontal lattice have a very simple structure, so the manufacturing process of the fasteners can be simplified and the work of assembling the lattice can be simplified. It becomes easier. Moreover, the lattice assembly using the fasteners of the present invention elastically locks the protrusions of the fastener locking pieces to the locking protrusions of the grid, and the protrusions of the fastener locking side pieces of the fasteners are elastically locked to the locking protrusions of the lattice. Since the gratings are elastically locked to the inner wall of the surface, the grids can be securely fixed, and the grids will not come off or wobble. Therefore, the present invention has the advantage that a reliable lattice body can be obtained through simple manufacturing and work processes.
