Description

[Detailed Description of the Invention] This invention relates to a muntin-like connection device for vertical and horizontal bars made of extruded shapes such as aluminum.

This type of coupling device assembles both the vertical and horizontal beams flush by providing notches in each of the vertical and horizontal beams that engage with the other. In addition, as for mutual fixing means, for example, screwing in screws from the front or rear side would be unsightly, so both bars are formed into a gutter-like or hollow shape, and a joint made of resin is attached to both bars at the notch. They are mated. However, with such conventional connecting devices for vertical and horizontal bars, the connection work is troublesome, and the connecting tool is connected to the vertical and horizontal bars by elastic restoring force, so it is difficult to obtain a strong connection structure. (For example, Utility Model No. 32601 devised in 1973,
−140513 devised).

The purpose of this invention is to solve the drawbacks of the conventional vertical and horizontal beam connection devices as described above.

Next, an embodiment of this invention will be described based on the drawings.

1 to 3 show a first embodiment of this invention.

Reference numeral 1 denotes vertical bars of the grid, 2 indicates horizontal bars, and plate-shaped connecting pieces 3 are used to connect them.

The vertical beam 1 has a middle wall 6 between a wide front wall 4 and a narrow rear wall 5, and has protrusions 7, 7 facing each other on the inner surfaces of the front and rear walls 4, 5 at a distance from the middle wall 6. By forming a groove-shaped guide path 8 along one surface of the inner wall 6, the connecting piece 3 can slide while being sandwiched between the front and rear walls 4 and 5, and a groove-shaped guide path 8 is provided on the opposite side of the guide path 8. Bis pockets 9, 9 for connection to the lattice crosspieces (not shown) are formed.

The horizontal beam 2 is formed into a substantially H-shaped cross section by providing a middle wall 12 between a front wall 10 and a rear wall 11 having the same width. In addition, a bis pocket 13 for connecting to the tack bar is formed in the center of the inner wall 12 and has a C-shaped cross section, and a hook portion 14 on which the connecting piece 3 is hooked is provided protruding from the closed side of the bis pocket 13. It is formed into a substantially T-shaped cross section.

Further, the vertical bar 1 and the horizontal bar 2 are formed to have the same thickness, and cutouts 15 and 16 that engage with each other are provided at the locations where they intersect. Then, both cutout portions 15,
The depth of 16 is the same as the thickness of crosspieces 1 and 2 when both are combined. Of these, the notch 16 of the horizontal bar 2 is formed shallowly so as to leave the hooking part 14 without being removed, and the notch 15 of the vertical bar 1 is formed deep so that the guide path 8 is cut out. Also, since the front wall 10 of the horizontal bar 2 is removed due to the notch 16, the notch 15 of the vertical bar 1 has a deep part 15a narrow enough to fit the hooking part 14. There is.

Next, the connecting piece 3 is formed into a plate shape that fits into the groove-shaped guide path 8 provided on the vertical bar 1 as described above, and has a notch-shaped engagement part at the tip that fits into the hook part 14 of the horizontal bar 2. Part 1
7 is provided, and a cutout edge 18 is formed on one side edge from the tip to approximately the middle part, and the rear wall 11 of the horizontal crosspiece 2 is
This is done so as not to collide with the bent end edge 20 of.

In the above configuration, the vertical bar 1 and the horizontal bar 2 are connected to the notch 1
When 5 and 16 are combined, both bars 1 and 2 are prevented from shifting from each other in the longitudinal direction.Next, when the connecting piece 3 inserted into the guide path 8 butts against the horizontal bar 2, the connecting piece 3 Since the engaging part 17 of the horizontal bar 2 is caught on the hook part 14 of the horizontal bar 2, both bars 1 and 2 cannot be disassembled. In this case, it is necessary to fix the connecting piece 3 so that it does not come off the hook 14, but no special means is required for this fixing. For example, a screw hole 19a for a screw 19 is provided in the inner wall 6 of the vertical beam 1,
You can just use screw 19 to stop it from returning.
Further, in a state where the connecting piece 3 is prevented from coming off due to its own weight, that is, when the direction of arrow P is upward in the drawing, a stopping means is not necessarily required. In addition, if a non-return claw or the like is provided in the notch-shaped engagement portion 17 of the connecting piece 3, a state of connection with the hooking portion 14 that will not come off can be obtained by that alone.

Before assembling the vertical and horizontal beams 1 and 2, as shown by the dashed line in FIG.
When connecting the vertical and horizontal beams 1 and 2, the adhesive tape can be peeled off and the connecting piece 3 can be immediately hooked onto the horizontal beam 2.

Furthermore, since the hooking portion 14 of the horizontal beam 2 must not be scraped off when the cutout portion 16 is formed, the cutout portion 16 is formed so shallow that it does not reach the hooking portion 14.
On the contrary, the notch 15 of the vertical bar 1 needs to be formed deeply. However, since the rear wall 5 of the vertical beam 1 is formed narrow in width, the notch 15 can be easily formed deeper than that surface. If necessary, the rear wall 5 may be made wider using a complementary member 5a, as shown in the second and subsequent embodiments.

In other words, Figures 4 and 5, Figures 6 and 7, and Figures 8 and 9 respectively show the second, third, and fourth embodiments in which this invention is applied to lattice doors. ,
In either case, a complementary member 5a having the same width as the front wall 4 is combined with the vertical beam 1, and a groove 21 for fitting plate glass or the like is formed between them.

As explained above, this invention forms a guide path on one crosspiece into which the connecting piece fits so that it can slide in the longitudinal direction, and a hook on the other crosspiece to hook the connecting piece guided by the guide path. A stop portion is provided, the cutout portion of the one crosspiece is formed by cutting out a guide path to the extent that the hooking portion of the other crosspiece is fitted, and the cutout portion of the other crosspiece is formed by cutting out the hooking portion. Since the connecting piece is formed to a depth that does not interfere with the movement, and the connecting piece is provided with an engaging part that corresponds to the hooking part, no troublesome operations are required to hook the connecting piece to the other crosspiece, and it can be done with just one touch. Vertical and horizontal bars can be connected, and the connection work is extremely easy. Moreover, the hooks between the vertical and horizontal bars of the connecting piece are deep and do not come off easily, unlike those that use elasticity, so the combination of vertical and horizontal bars will never come off unless the connecting piece is removed. A connected structure can be obtained.
