Description

[Detailed Description of the Invention] This invention relates to a doorway lattice made of an extruded aluminum alloy material.

The sleeve lattice is installed by sandwiching it between the pillars of the entrance or between the pillars and the wall, but because it is assembled in a factory and installed on site, even if it is made according to the dimensions, it will not fit on the actual site. However, because they do not fit, it may be impossible to install them, or it may involve troublesome work such as cutting the ends of the horizontal bars, and in this respect, conventional sleeve lattices have been difficult to mass produce.

Therefore, this idea was designed to make it possible to install the door lattice in a stable state with extremely simple work, even if the dimensions between the pillar and wall etc. at the entrance are of a certain size. It is intended to.

Hereinafter, embodiments of this invention will be described with reference to the drawings.

The sleeve lattice P connects a large number of vertical bars 3 between an upper horizontal bar 1 and a lower horizontal bar 2, and connects caps 4, 5 at both ends of each horizontal bar 1, 2 to cover the outside of the iron part. Fit the connecting cap 4,
5 can be moved in the longitudinal direction relative to the horizontal bars 1 and 2, and can be fixed with adjustment screws 6.

In other words, the horizontal bars 1 and 2 are formed into a tubular shape with a rectangular cross section, and one through hole 7 for the adjustment screw 6 is formed at each end of the upper wall 1a of the upper horizontal bar 1 and the lower wall 2a of the lower horizontal bar 2. The through holes 7 are formed as elongated holes in the longitudinal direction of the horizontal bars 1 and 2, and the upper and lower holes 1 protrude into the base walls 8 of the caps 4 and 5 into the horizontal bars 1 and 2.
A pair of support pieces 9a and 9b are provided protrudingly, and a screw hole 10 into which the adjustment screw 6 is screwed is provided in the support piece 9a on the side of the through hole 7.

Further, the inner periphery of the cap 4 is provided with holding grooves for fitting and holding the ends of the horizontal bars 1 and 2.

Within the groove depth of this holding groove, the lengthwise adjustment of the caps 4, 5 and the horizontal beam 1°2 is made.

Note that the upper cap 4 may be provided with only the upper support piece 9a, and the support pieces of the upper and lower caps 4 and 5 may not be divided into upper and lower parts, but may be formed into a short cylindrical shape that fits into the horizontal bars 1 and 2. good.

Next, the caps 4 and 5 are integrally formed with a fixing piece 13 having a sloped surface toward the mounting side to be attached to the pillar 11 or wall 12 of the house, and the fixing piece 13 is attached to the upper cap 4 from the upper end to the lower cap 5. are provided protruding from the lower end, and through holes 15 for mounting screws 14 are provided in the inclined surfaces of each fixing piece 13.

Since the sleeve lattice according to this invention has the above-mentioned structure, in the factory there are 1 horizontal bars, 2 horizontal bars. and vertical bars 3 are connected, and the connecting caps 4 and 5 are attached to both ends of the horizontal bars 1 and 20 with adjustment screws 6 before shipping.

At the site, as shown in Figure 1, the screw 14 is inserted between the pillar 11 and the wall 12, and the screw 14 is inserted into the pillar 1 through the through hole 15 of the fixing piece 13.
1 and the pillar 11' in the wall 12 and attach the cap 4 to them.
, 5 are fixed, but during this series of steps, the adjusting screw 6 is
If it is loosened, the through holes 7 of the horizontal bars 1 and 2 through which the screws 6 pass are formed into elongated holes, so the cap 4.5 can be adjusted in the longitudinal direction relative to the horizontal bars 1 and 2. Possible, Pillar 1
Even if the dimensions between the pillar 11 and the wall 12 have a certain size, the width between the caps 4, 4. It is very easy to fit the caps 4, 4, 5, 5 at both ends together.

Next, after the caps 4 and 5 are fixed, the horizontal bars 1 and 2 are fixed to the caps 4 and 5 by tightening the adjustment screws 6.

At this time, the ends of each of the horizontal bars 1 and 2 are fitted and held in the retaining grooves provided on the inner circumference of the caps 4 and 5, so the tightening of the adjustment screw 6 requires that the ends of the horizontal bars be held at the front. It can be temporarily fixed while fitted in the groove, and since the holding groove receives the weight of the horizontal bars 1 and 20, the weight load on the support piece 9a can be reduced, and the ends of the horizontal bars 1.2 are held. Since it is hidden within the groove, finishing machining of the edge is not required.

Furthermore, since the mounting side of the fixing pieces 13 of the caps 4 and 5 is an inclined surface, it is easy to drive the screws 14 into the mounting, and even when the sleeve grid is assembled, the grid can be mounted using the screws 140. It does not interfere with driving,
The caps 4 and 5 can be easily attached to pillars, etc.

The caps 4 and 5 are molded from synthetic resin, and as shown in FIGS. 6 and 7, a screw hole 10 is provided at the center of the width of the support piece 9a, and as the support piece 9a moves toward the tip, the center of the width increases. If the adjustment screw 6 is screwed into the screw hole 10 and tightened as shown in FIG. 1 and a strong connection is obtained.

As mentioned above, the sleeve lattice according to this invention adjusts the width between the caps on both the left and right ends accordingly, even if the dimensions between the pillar and the wall etc. where it is attached to the entrance are somewhat large or small.
It is very convenient because it can be installed in a stable state and its operation is extremely simple, and it has the effect of being suitable for mass production according to standards.
