Description

[Detailed Description of the Invention] The present invention relates to a lattice door in which a vertical lattice and horizontal bars are provided inside the upper and lower stiles and the left and right stiles.

Conventional lattice doors are assembled by screwing left and right vertical frames to upper and lower frames and horizontal frames to which a plurality of vertical lattices are attached. However, when screwing a vertical stile to a horizontal frame, the screws must be screwed from a vertical stile with a large cross-section to a horizontal frame with a small cross-section, which makes the screw-fastening work very difficult. Since the left and right vertical frames and horizontal beams are connected only by screws, there is a gap between the two members, which causes wobbling after the frames are assembled.

This invention was made in view of the above points, and it is possible to fix the vertical stile and the horizontal frame with screws by interposing the vertical frame between the vertical stile and the horizontal frame without directly connecting the vertical stile and the horizontal frame. The present invention proposes a lattice door which allows the frame assembly to be performed extremely easily by omitting the above-mentioned step, and which also prevents rattling between each stile, the horizontal bars, and the vertical lattice due to the vertical edge bars. be.

An embodiment of the present invention shown in the drawings will be described in detail below. Figure 1 is the front view of the gate, Figure 2 is the same as Figure 1.
AA line enlarged cross-sectional view, Figure 3 is the central longitudinal cross-sectional view of Figure 2, Figure 4 is an exploded front view of the lattice door, and Figure 5 is the second
FIG. 6 is an exploded view of the main parts of FIG. 3.

In each of the above figures, the lattice door of this embodiment is provided with a plurality of vertical lattices 4 and an appropriate number of horizontal bars 3 inside the upper and lower frames 1 and the left and right vertical frames 2. A plurality of vertical lattices 4, 4 are fixed, vertical edge bars 5 are fixed to both ends of the horizontal frame 3, and the left and right vertical frames 2 are fixed.
While fitting the vertical edge crosspiece 5 into the recess 6 on the inner surface of the
The left and right vertical frames 2 are screwed to the upper and lower frames 1.

The plurality of vertical lattices 4, 4 are each made of a hollow rectangular elongated member, and are each fixed to an appropriate number of horizontal bars 3 arranged at arbitrary intervals in the vertical direction with screws 13. be.

As shown in FIG. 6, the horizontal crosspiece 3 has a main body with a horizontally T-shaped cross section and two cover materials 9, 9.
It is made to be removably attached. The cover material 9 is attached to the main body after the vertical lattice 4 is fixed to the horizontal beams 3 with screws 13. Therefore, it facilitates the fixing work with the screws 13 and also makes it possible to remove the screws 13. It can be coated to give a good appearance. Further, a through hole 10 is provided in the center of the main body of the horizontal beam 3.

Each of the upper and lower frames 1, 1 is provided with a mounting piece 11 protruding inwardly on its inner side, and screws 13 are attached to each of the upper and lower ends of the plurality of vertical lattices 4, 4 to this mounting piece 11.
It will stop at. After finishing the fixation with the screws 13, a cover material 19 having the same shape as the above-mentioned cover material 9 is attached to the mounting piece 11. The mounting pieces 11 allow the vertical lattice 4 to be easily fixed.

As shown in FIG. 5, the vertical edge frame 5 is made of a long member having a substantially U-shaped cross section, and screws 7 are screwed into the through holes 10 of the horizontal frame 3 at the side ends of the horizontal frame 3. It is fastened by. Since the vertical edge crosspiece 5 is formed by bending both edges of a flat plate-like piece, it is extremely easy to screw the screws into the horizontal cross-piece 3 by passing the screws 7 through the holes in the flat plate-like piece. It can be done.

Next, the left and right stiles 2, 2 have recesses 6 on the opposing inner surfaces.
is provided, and the vertical edge beam 5 is fitted into this recess 6. This recess 6 is
It has an internal shape that approximately matches the width of the vertical edge bar 5. Further, the vertical edge beam 5 is fitted into the recess 6, leaving the upper and lower ends of the vertical stile 2 intact. Next, the upper and lower ends of the vertical frames 2, 2 are fixed to the upper and lower frames 1, 1 by screwing the screws 8 into the screw holes 12, thereby completing the frame assembly.

The frames 1 and 2, horizontal bars 3, vertical lattice 4, vertical edge bars 5, etc. described above are mainly formed from extruded materials such as aluminum.

As shown in FIGS. 2 and 3, the lattice door body of this embodiment described above has auxiliary members 21 and 21 at the entrance/exit portion 20.
It can be opened and closed using a hinge 22. Further, as shown in FIG. 1, the lattice door body of this embodiment can also be used for a sliding door 24 that is housed in the central entrance 23.

As described above, in the present invention, the vertical edge bars are fixed to both ends of the horizontal frame to which the vertical lattice is fixed, and the left and right vertical frames are not fixed to the horizontal frames, but the vertical edge frames are attached to the horizontal frames. Since the horizontal frame is screwed to the upper and lower frames while being fitted into the recess, the time-consuming assembly work of screwing the horizontal frame from the vertical frame can be eliminated, and the frame assembly work can be made extremely simple. On the other hand, the work of attaching the horizontal frame and the vertical frame can be easily done because the vertical frame is extremely thin compared to the vertical frame. Moreover, since the vertical stile and the vertical edge frame are not screwed together, it is possible to save the effort of drilling holes in both members and aligning the holes. Furthermore, the vertical edge bars fixed to the horizontal bars are fitted into the recesses provided in the vertical stile, and the upper and lower ends of each vertical lattice are fixed to the upper and lower frames, so the horizontal bars and vertical The lattice and each frame are tightly bonded to each other, so there is no wobbling after the frame is assembled.
