Description

[Detailed Description of the Invention] The present invention relates to a cross-shaped muntin lattice used in sliding entrance doors, etc., as shown in FIG.

The kumiko currently in use is either cut out both the main and horizontal branches and put them together and then fixed or screwed together, or the vertical bars are cut out in the shape of horizontal bars, and the horizontal bars are inserted through them. There are, but
All of these are difficult to process and difficult to assemble.

The present invention provides a muntin lattice that does not have such difficulties, and one embodiment thereof will now be described with reference to the accompanying drawings.

There are only three types of parts used in the muntin of the present invention: one crosspiece such as a horizontal lattice, the other crosspiece such as a vertical crosspiece, and fixed parts, all of which are made of metal such as aluminum or iron. .

The two crosspieces are suitable for mass production at low cost as elongated materials using a so-called extrusion molding method, and the fixing parts can be easily produced by pressing plate materials.

One of the crosspieces 20 is a long rectangular member with a substantially rectangular cross section as shown in FIG.
2, 23.24, both opposing sides 22.24
are provided with recesses 25 and 26 for attachment, respectively.

Although this recess is shown as a groove in the figure, it could also be a step in the surface as shown in FIG.

A locking claw provided on a fixed component, which will be described later, is locked into this recess.

As shown in FIG. 2, the other crosspiece 10 has an angular cross section.
It is a long, letter-shaped material.

To be more precise, its shape is a hypothetical square hollow member including a rectangle, with the center portion of its upper surface being cut off to leave locking strips 11 and 15 on both ends of the upper surface.

The surfaces that are successively bent at right angles from the locking strip 11 on the left end side and connected to each other are named a left wall 12, a base wall 13, a right wall 14, and a right locking strip 15, respectively.

Moreover, this crosspiece 10 is provided with a notch 40 at a position where it intersects with one crosspiece 20 in a cross shape, through which one of the crosspieces is attached via a fixed part.

The size of the notch is equal to the width l of one crosspiece plus twice the thickness of the fixed component upright wall, and its depth is equal to the height h of one crosspiece plus the thickness S of the fixed component board. The appropriate depth is considered to be appropriate.

The fixing component 30 serves to fit into the notch 40 and to engage one of the crosspieces 20 through this, and as shown in the figure, it overlaps the base wall 13 of the notch 40. A new upright wall 32 that closes the hollow part of the other crosspiece 10 is symmetrically extended from both opposing sides of the substrate 31 in the right angle direction, and from the left and right sides of the upright wall 32 are left and right crimp wings 33, 34.
The wings are outstretched with their tips spread out.

Above, I used the expression ``hollow part'' on the other crosspiece, but of course the term ``hollow part'' comes from the explanation of the shape of the iron pillar as a square hollow member, and rather it is called the hollow part of the other crosspiece.
This is an end face of the internal space surrounded by 4-15.

Also, the state in which the crimp blades 33 and 34 have their tips expanded means that
This means that the middle of the tip is slightly wider than the width of the standing wall, and by pressing the tip with your fingertips, you can push the wing into the hollow section. The wings press against the inner surfaces of the side walls 12, 14, thereby serving to fix the fixing member 30 to the other crosspiece 10.

In addition, the above-mentioned upright wall 32 has an inwardly directed engaging claw 35.
is installed protrudingly.

It has already been mentioned that the upstanding walls 32 having these compression wings are provided symmetrically on both sides of the substrate 31.

On the symmetrical standing wall side, a dash has been added to the symbol in the drawing.

In addition, in the figure, a shoulder 36 is provided on the upper edge of the crimp blade, and this shoulder comes into contact with the locking strips 11 and 15 of the other crosspiece, and the fixed part 36
0 can be securely locked to the other crosspiece 10.

In order to assemble a muntin lattice using the three parts described above, as shown in FIG. 33 and 34 are crimped and fitted to the left and right side walls 12 and 14.

Then, when one crosspiece 20 is pushed between the two upright walls 32 and 32' of the fixed part attached to the other crosspiece 10, the locking claws 35 and 35' fit into the locking recesses 25 and 26, and one side The crosspiece is fixed to the fixing part, and thus to the other crosspiece.

The state in which such fixation is completed is shown in Fig. 1, Fig. 3, which is an enlarged rear view of the part, and Fig. 4, which is a sectional view taken along line A-A in Fig. 3.
clearly shown in the figure.

In order to assemble the fittings as shown in Fig. 1, a predetermined number of one side crosspieces 20 are assembled, and the frame materials of upper P, lower Q, left R1 and right R' are assembled into a rectangular shape. The other crosspiece 10 fitted with the fixed part 30 may be pushed in at a predetermined interval.
