Description

[Detailed Description of the Invention] This invention relates to a device for fitting and fixing a lattice into a frame of a lattice door or a panel lattice.

The purpose is to propose a grid fixing device that allows the ends of the grid to be easily fitted and fixed into the grooves of the frame, and that allows the grid to be installed in a stable state without wobbling.

Figure 1 shows a lattice door, and Figure 2 shows an example of a conventional lattice fixing device for the upper frame of a lattice door.The upper frame 1 has a groove 2 along the longitudinal direction of the body. Notches 4 are formed in the strip-like extension pieces 3 at appropriate intervals, and the fifth end of the grid is inserted into the groove 2 through the notches 4 to create elasticity between the groove side walls 6 and the sides of the grid 5. The grid 5 was fixed by fitting a fixing member 7 having the above.

In addition, in FIG. 2, glass is fitted on the indoor side parallel to the grid.

However, in this conventional device, it took a lot of effort to fit the fixing material 7 and the grid 5 and fix it, resulting in poor construction efficiency.

This idea was made by focusing on the above-mentioned problems.

This will be explained below with reference to the illustrated embodiments.

The upper frame 1 has a groove 2 along its lower surface in the longitudinal direction, and a strip P and a strip P protrude from the opening of the groove 2.

The extending piece 3 is provided with a suitable notch 4 for retaining the lattice 5, and the protruding end blocks of the blocks and 8 of the lattice 5 are inserted into the groove 2 through the notch 4.

□ In FIGS. 3 and 4, a lattice fixing block 8 is protruded from the upper end of the quadrangular prismatic lattice 5.

This fixing block 8 is made of synthetic resin, and its lower part fits into the cavity 9 of the lattice 5 and is fixed with screws 10.

The upwardly protruding portion is a cube having three side surfaces substantially along the side surfaces of the lattice 5, and an elastic protrusion 11, which is an uneven strip, is formed on the lower side.

The width of the lattice 5 including the fixed block 8 is formed to be larger than the width of the groove 2, and the elastic protrusion 11 projects outward from one side of the lattice 5.

The state in which the end of the grid 5 is inserted is shown in Figure 3.
An elastic protrusion 11 formed on one side of the fixed block 8 is pressed against the structure side wall 6 of the upper frame and fixed in a stable state without wobbling.

In the above embodiment, the fixing block 8 is fixed with screws, but the use of screws is not necessarily necessary; for example, it may be simply press-fitted.

Furthermore, it goes without saying that this fixing device can be applied not only to the lattice door of the embodiment but also to a surface lattice and the like.

The grid fixing device of this invention is made of the above bark, and the fixing blocks protruding from the ends of the grid are IA' from one side of the grid.
Since it is held in pressure contact with the groove side wall of the leprosy protrusion number frame protruding at A, during assembly, it can be locked and fixed by simply fitting the end portion to which the fixing block is attached.

This eliminates the need for fitting elastic fixing materials between the groove walls or fixing them with screws, as required in the past.
You can measure the improvement of work efficiency.

Furthermore, the elastic protrusions strongly press against the groove sidewalls and keep the grid stable for a long period of time without wobbling.

5. Furthermore, since the fixed block is made of composite material, there is an advantage that even if there is a slight dimensional deviation in the fitting part, this can be absorbed and the block can be fitted without difficulty.
