Description

Door-joint structure of a multi-layer grid

The present invention relates to a double lattice window, and in particular, the edges of the lattice frame supporting the outer portion of the lattice window are fixed to each other with a bending bracket, and horizontal to the center of the vertical and horizontal lattice rods placed in the horizontal and vertical directions on the lattice frame. After fixing the brackets, the fitting protrusions of the fixing brackets fitted to the grid bars are inserted into the fitting holes of the grid frames to form the doors of the grid windows, simplifying the composition of the doors and simplifying the assembly work. It relates to a door coupling structure of a double lattice window.

Generally, the types of windows include sliding windows that slide open and close by hand, sliding windows that open and close windows by sliding the windows horizontally in the window frame, and built-in windows fixed in place without the windows being joined to the wall and not closed. Sliding windows are widely used, and sliding windows that open and close horizontally among these windows are most widely used due to the convenience of opening and closing the windows and little space to occupy when the windows are opened and closed.

In such various windows, in order to improve sound insulation, windproof, and heat dissipation effect, recently, two-layer windows in which two sheets of glass are fixed to each other at regular intervals are popularly used. Make a grid of grids and align the grids with each other in the direction of intersection, and place the grid frame on the outside of the intersected grids and fix the grids with screws to fix each other. After making the frame, two sheets of glass are placed on the outside, and the lattice frame is inserted into the window fixing member to caulk and finally produce the double-layer door.

That is, in the related art, after the grids of the windows are configured to cross each other in a cross shape, in order to fix the two with the grid frame on the outside, the fixing frames are fixed by using screws or the like after fitting the corner portions.

However, in order to manufacture a conventional double-layered window, the grid frame intersecting with each other vertically and horizontally is put together and the grid frame is placed on the outside, and then the grid frames of the rectangular frame shape are tightened with each other using fixing screws, and then fixed between the panes. The assembly work to assemble the lattice frame together with the fixing screw is cumbersome, and the assembly work and productivity are deteriorated, and the fixing screw is released when the impact is continuously applied during the use of the multilayer glass door. There was a problem.

The present invention has been devised in view of this point, and the edges of the grid frame supporting the outer portion of the grid window are fixed to each other with a bending bracket, and the horizontal and vertical grid bars placed in the horizontal and vertical directions on the grid frame are horizontal. After the brackets are fixed, the fitting brackets of the grating rods are inserted into the grating holes of the grating frame to fix the doors of the grid windows, simplifying the composition of the doors and simplifying the assembly work. The purpose of the present invention is to improve productivity, and to prevent the fixing screw of the assembled door from being loosened.

For this purpose, a plurality of first lattice frame is formed vertically opposed to each other and the first inclined surface is inclined at a predetermined angle at both ends of the first hollow, the plurality of first grating frame is formed on the inner surface at a predetermined interval, A second lattice frame having a second fitting hole in contact with upper and lower sides of the first inclined plane of the first lattice frame and penetrating into a second hollow therein; a first hollow and A bending bracket having a locking jaw portion formed to be press-fitted into the second hollow of the second grid frame, and a fitting protrusion is fixed to the first and second fitting holes of the first and second grid frames, and the locking jaw portion is formed on the outer circumferential surface thereof. A plurality of fixed brackets, a plurality of horizontal grid rods formed with a horizontal hollow pressed into the locking jaw portion of the fixing bracket, and the side grooves that the other end of the horizontal grid rods are fitted on both sides are formed on both sides and both sides The vertical hollow of the end is a horizontal bracket that is fitted into the vertical grid rod coupled to the fixing bracket fitted to the second fitting hole of the second grid frame and the side grooves of the vertical grid rod and press-fitted into the horizontal hollow of the horizontal grid rods on both sides to fix both. This is achieved by providing a door-joint structure of the configured double-lattice windows.

Hereinafter, the operation and effects of the present invention will be described based on the accompanying drawings.

First, looking at the assembly state of the door coupling structure of the multi-layer grid window according to the present invention, first, the method of assembling the fixing frame (1) of the present invention can be appropriately selected as needed, but will be described based on an embodiment First, the horizontal bracket 60 is positioned in the side groove 44 formed by being cut on both sides of the vertical grid rod 40, and then the horizontal hollow 32 of each horizontal grid rod 30 is inserted from both sides. Assembling a plurality of horizontal grid rods 30 on both sides of the vertical grid rods 40 at regular intervals, the assembly bracket 50 is also fitted to the vertical hollow 42 of the vertical grid rods 40.

In addition, the fitting projections 52 of the fixing bracket 50 coupled to the vertical hollow 42 of the vertical grid rod 40 and the horizontal hollow 32 of the horizontal grid rod 40 are first and second grid frames. The first and second hollow holes 12 and 22 of the first and second lattice frames 10 and 20 may be simultaneously inserted into the first and second fitting holes 14 and 24 of the 10 and 20. By pressing and bending the bending bracket 70 into the assembly, the shape of the fixing frame 1 is finally manufactured. The locking jaw portion 54 protrudes from the outer circumferential surface of each bracket 50, 60, 70. Since the 62 and 72 are formed to be larger than the width of the inner surface to be fitted, the lattice frames 10 and 20 and the horizontal and vertical lattice bars 39 and 40 are mutually pressurized even after being pressed into each part. There is no separation.

Then, when the fixing frame 1 is configured in this way, as shown in FIG. 2, the plate glass 90 is placed on both sides of the fixing frame 10 and inserted into the recesses 82 of the fixing member 80. The assembly is made to make the door (2), look at the cross-sectional view of Figure 4 of the combined door (2), there is a tube rod 100 of the square cross-section in which the dehumidifier is installed to the outside of the grid frame 20, In order to fix the plate glass 90, the packing 120 presses the plate glass 90 on both sides, and the inner caulking part 110 and the outer caulking part 130 which can fix the plate glass 90 to the bottom and the upper outside thereof. ) Is combined.

As such, the fixing frame 1 according to the present invention does not require any fixing screws, and firmly mutually secure the first and second lattice rods 10 and 20 and the horizontal and vertical lattice rods 30 and 40. It will be assembled and tightly assembled, and the assembly is remarkably improved because the assembly is completed by simply aligning the position of each member and pushing each member firmly to each other, saving time for tightening the fixing screw. Will be done.

Therefore, when the door coupling structure of the lattice window according to the present invention is used, the edges of the grid frame supporting the outer part of the grid window are fixed to each other with a bending bracket, and the vertical and horizontal grids placed in the horizontal and vertical directions on the grid frame. After the horizontal bracket is fixed to the center of the rod, the fitting bracket of the fixed bracket inserted into the grid bar is inserted into the fitting hole of the grid frame to configure the door of the grid window, simplifying the composition of the door and simplifying the assembly work. In order to improve the assembly and productivity, it is a very useful design to ensure the tightness of the door because the distribution of the load applied to the fixed portion is made more effectively than when assembled with a fixing screw.
