Description

[Detailed Description of the Invention] The present invention relates to a structure for connecting vertical bars of metal muntins assembled from extruded aluminum or aluminum alloy members in a lattice door or the like.

When forming a crossing joint using vertical and horizontal bars of metal muntins, screwing is generally used, and this screwing requires a considerable amount of effort.

Therefore, the present invention provides a connecting structure of vertical and horizontal beams that can be connected extremely easily without using screws and that can provide a stable connected state without rattling.

In the following, the present invention will be explained based on embodiments shown in the drawings.

FIG. 1 is an exploded perspective view of the connecting structure of vertical and horizontal bars according to the present invention, FIG. 2 is an assembled plan view, and FIGS. 3 and 4 are cross-sectional views taken along the lines X-X and Y-Y in FIG. In FIGS. 5 to 8 showing the connectors, the present invention shows that the hollow extruded material is used to connect the vertical and horizontal beams 1 and 2 from appropriate positions on the back wall 1b of one of the beams 1 and the front wall 2a of the other beam 2. In addition to providing notches 3 and 4 for cross-jointing joints, auxiliary notches 5 and 5 are provided by further notching the opposite end of the back wall 1b by a predetermined width in the longitudinal direction, and these are combined with each other. A synthetic resin type connector 6 is installed between the front wall 1a of the vertical bar 1 and the back wall 2b of the horizontal bar 2 at the positions of the notches 3 and 4, and the connector 6 is
A pair of upper and lower umbrella-shaped locking pieces 7 and 8 are integrally formed on the connector main body 6a so as to be expandable and retractable, and the tip of one of the locking pieces 7 is connected to the horizontal bar 2.
The tip of the other locking piece 8 abuts and locks on the inside surface of the back wall 1b of the vertical bar 1.

The vertical and horizontal bars 1 and 2 are formed from a hollow extruded material of aluminum or aluminum alloy.

Notch widths 3 a and 4 a and notch depths 3 b of notches 3 and 4
.

4b can take an appropriate value so that the vertical and horizontal bars 1 and 2 can be connected to form a crossing joint.

That is, the notch width 3a of the notch 3 is equal to the width of the side wall 2C9 of the horizontal beam 2.
2C, the notch depth 3b is adapted to the notch remaining portion 4C of the horizontal crosspiece 2, and similarly, the notch width 4a of the notch 4 is adapted to the interval between the side walls 1c and lc of the pillar 1, Further, the notch depth 4b is adapted to the notch remaining portion 3C of the pillar 1, respectively.

The auxiliary notch 5 is formed on the pillar 1 on which this notch 5 is provided.
A notch is formed to match the cross-sectional shape of the locking piece 8 that abuts and locks on the back wall 1b.

The reason why the auxiliary notch 5 is provided in the back wall 1b of the pillar 1 is as follows.

That is, in the case of this example, as will be explained in detail later, the connector 6
(FIG. 9) is first attached to the horizontal crosspiece 2, and then the pillar 1 is assembled, and the locking piece 8 of the connecting tool 6 is located outside the cutout remaining portion 4C of the horizontal crosspiece 2.

Therefore, when assembling the pillars 1, it is necessary to provide a separate relief for the thickness of the locking piece 8 at the end opposite the notch of the rear wall 1b of the pillars.

In other words, the notch width 3a in the back wall 1b is equal to the interval length of the side walls 2C, 2C, and the wall thickness of the locking pieces 8, 8 is 8t+.
8 is expected to be more than 8.

Note that when the connecting tool 6 is attached to the pillar 1 and the horizontal crosspiece 2 is subsequently assembled, the auxiliary notch 5 is provided in the surface wall 2a of the horizontal crosspiece 2, and is formed at the end opposite to the notch. The separate notch that should be made is equivalent to the wall thickness 7t+7 of the locking pieces 7, 7.

However, when the horizontal beams 2 are combined from the surface wall 1a side of the pillar 1 to form a crossing joint, the above-mentioned notches 3 and 4
The positions of the notches will be interchanged.

The connector 6 is constructed by integrally molding the main body 6a and a pair of upper and lower umbrella-shaped locking pieces 7.8 of synthetic resin, and the locking pieces 7.8 are made elastic so that they can expand and contract. There is.

The vertical width P, horizontal width Q, and height R of the main body 6a are as follows.

That is, the vertical width P is equal to the inner surface interval length of the side wall 2C92C of the horizontal beam 2, and the horizontal width Q is equal to the length of the inner surface interval of the side wall 2C92C of the horizontal beam 2.
C, the height R is set equal to the length of the inner surface interval, and the height R is set equal to the length R of the inner surface, since the connecting tool 6 is installed between the front wall 1a of the pillar 1 and the back wall 2b of the horizontal crosspiece 2. surface wall 1 in
It has the length between a and the back wall 2b.

Furthermore, the vertical protrusion heights 7a, 8a of the locking pieces 7, 8 are as follows.

The protruding height 7a of the locking piece 7, that is, the vertical height from the bottom surface of the main body 6a to the tip of the iron piece 7, is such that the tip of the piece 7 comes into contact with the front and back walls 2a of the horizontal bar 2. , 2b, and on the other hand, the protrusion height 8a of the locking piece 8, that is, the main body 6
The vertical height from the upper surface of a to the tip of the iron piece 8 is such that the tip of the piece 8 is in contact with the back wall 1b of the column 1.
The length is between a and lb.

Further, the wall thickness 7t of the locking piece 7 is formed to be the same as or less than the wall thickness of the pillar side wall 1C, and the sum of the width Q and the wall thickness 7t of the locking pieces 7, 7 is lateral. It is configured so that the width is not larger than the notch width 4a of the crosspiece 2.

Note that the wall thickness 8t of the locking piece 8 is different from that of the locking piece 7 and can be selected to have an arbitrary value.

Of course, if the order in which the connectors 6 are attached is different as described above, the method for selecting the wall thicknesses 7t and 8t may be changed.

Next, when combining the vertical and horizontal bars 1 and 2 using the connector 6, the connector 6 is first attached to the notch 4 of the horizontal bar 2.

This installation is accomplished by aligning the locking pieces 7 in the longitudinal direction of the horizontal beam 2 and compressing them in the direction of the main body 6a.

When the connector 6 is attached to the horizontal beam 2, the locking pieces 7.7 are restored and expanded due to their elastic force, so the tips of the pieces 7 come into contact with the inner surface of the surface wall 2a, and thereby The connector 6 is locked to the horizontal beam 2.

At this time, the locking pieces 8, 8 are located outside the side wall 2C92C, that is, outside the notch remaining portion 4C, and the shape is such that the iron piece 8 and the main body 6a hold the notch remaining portion 4C (Fig. 9).
The above-mentioned locking can be achieved reliably by avoiding the situation in which the connecting tool 6 moves in the longitudinal direction of the horizontal beam 2.

Thus, FIG. 10 is a cross-sectional view of the horizontal crosspiece 2 (FIG. 9) to which the connector 6 is attached.

Next, the pillar 1 is assembled so that the notch 3 thereof engages with the horizontal bar notch 4 and the connector 6.

At this time, as shown in FIGS. 11 and 12, the locking piece 8 engages with the auxiliary notch 5 of the pillar 1, and moves relatively while being compressed in the direction of the main body 6a, thereby completing the above combination. .

Therefore, as shown in FIG. 13 and the above-mentioned FIG. 4,
- The immediately compressed locking pieces 8, 8 are disengaged from the auxiliary notch 5 and expand in the same way as the locking piece 7, and the tip of the piece 8 is attached to the back wall of the pillar 1. It comes into contact with the inner surface of 1b, thereby locking the connecting tool 6 and the column 1, and thus connecting and locking the vertical and horizontal beams 1.degree.2.

In addition, when the auxiliary notch 5 is provided on the horizontal beam 2,
In the above-mentioned combination of the vertical and horizontal bars 1 and 2, the connection tool 6 and the pillar 1 are first connected.

As explained above, the present invention provides notches that are combined with each other in a column made of hollow extruded material, and furthermore, a connecting tool is installed in the space formed by the combined notches, and the connecting tool has a pair of upper and lower umbrella-shaped locking pieces integrally molded on its main body so that they can expand and contract freely, so the tips of these locking pieces abut against the inner surface of the front wall or back wall of the vertical crosspiece. Therefore, the connection can be made extremely easily without the need for screw threading means, and it has the effect that a stable connection state without wobbling can be obtained.
