It is in.

The present invention will be explained in detail below by means of illustrated embodiments.

The panel block 1 is for forming the panel body 2, and includes an injection block 3 and an extrusion block 10. The injection block 3 is obtained by injection molding a synthetic resin such as vinyl chloride resin. As shown in FIG. 5, the block 3 is provided with a plurality of louver pieces 30 on the front plate and the back plate, respectively.

A hinge sliding arc surface 4, a stopper piece 5, and a rod shaft 6 at the tip of the stopper piece 5 are provided on the left and right sides of the injection block 3, respectively, symmetrically with respect to the center. A fitting protrusion 7 for fitting into a cylindrical shaft 14 and a fitting hole 8 of an extrusion block 10, which will be described later, is provided upright, and a fitting hole 8 is bored at the lower end.

In addition, a plurality of substantially frame-shaped fitting frames 9 are erected on the upper surface of the injection block 3, and fitting recesses (not shown) into which the fitting frames 9 are fitted are provided on the lower surface. There is.

The above-mentioned injection block 3 is used alone at the lower end of the panel body 2, or when connected continuously from the middle part to the lower end. A fitting frame 9 is provided protrudingly, and fitting protrusions 7 are provided protrudingly from both upper and lower ends of the rod shaft 6.
In addition, an injection block 3 used independently at the upper end of the panel body 2
A fitting frame 9 is provided protruding from both upper and lower surfaces of the shaft 6, a fitting hole 8 is provided at the upper end of the rod shaft 6, and a fitting protrusion 7 is provided at the lower end. A fitting recess is provided in the lower surface of the injection block 3 at the upper end, and a fitting hole 8 is provided in the lower end of the rod shaft 6.

The extruded block 10 is obtained by extrusion molding a synthetic resin such as vinyl chloride resin, and as shown in FIG. A reinforcing rib 11 is provided between the front plate and the back plate, and a plurality of reinforcing ribs 11 are spaced apart in the width direction of the extruded block 100.

On both left and right sides of the extrusion block 10, similarly to the injection block 3, a hinge sliding arc surface 12, a stopper piece 13, and a cylindrical shaft 14 at the tip of the stopper piece 13 are provided symmetrically with respect to the center.

The hinge 15 is formed by extrusion molding of aluminum, and is a long member with a substantially semicircular cross section, and its length is equal to the vertical height of the panel body 2. 3
As shown in the figure, the bearing has two grooves along the entire length of the upper and lower parts.
is the provision.

In forming the panel body 2, each of the fitting frames 9 facing each other is inserted between the hinge sliding arc surface 12 at the lower end of the extruded block 10 and the reinforcing rib 11, and between the adjacent reinforcing ribs 11. The fitting protrusion 7 is fitted into the lower end of the cylindrical shaft 14, and as shown in FIG. 5, 13, the rod shaft 6, and the cylinder shaft 14 are connected so as to face the road surface, panel caps (not shown) are attached to the upper end surface of the extrusion block 10 and the lower end surface of the injection block 3, respectively. A panel body 2 is formed.

Next, as shown in FIG. 3, the bearings are fitted with grooves 16 over the opposing cylindrical shafts 14 and rod shafts 6 of the two panel bodies 2, so that the opposite sides of the adjacent panel bodies 2 are connected to the front side. After the hinge 15a is foldably hinged, both upper and lower ends of the hinge 15a are supported by hinge caps (not shown) attached to the upper surface of the extrusion block 10 and the lower surface of the injection block 3.

Further, at the upper end of the hinge 15a, a follower guide 19 is urged upward by a spring.

Now, when fitting the bearing recess 16 across the cylinder shaft 14 and the rod shaft 6, the diameter of the lower part of the cylinder shaft 14 into which the fitting protrusion 7 is fitted becomes slightly larger, and the diameter may become smaller even when pressed. Therefore, once the bearing is fitted across the cylindrical shaft 14 and the rod shaft 6, the recessed strip 16 is difficult to come off, and the hinge 15a can be prevented from coming off.

The other side of the panel body 2, which has one side hinged with a hinge 15a, is similarly foldably hinged with a rear hinge 15b having approximately the same shape as the hinge 15a. A guide 20 is provided upright, and a door wheel 21 is provided vertically and rotatably below the hinge 15b.

Similarly, as shown in FIG.
Here, the hinges 15a and 15b are provided with stopper pieces 5 and 13 point-symmetrically provided on the left and right sides of the panel body 2, respectively, so that the front side of the panel body 2 protrudes at the hinge 15a. Furthermore, the hinge 15b can only be folded so that the rear side of the panel body 2 protrudes.

Further, an upper guide 20 provided above the hinge 15b is slidably inserted into the upper rail 22, and a door wheel 21 provided below the hinge 15b is slidably inserted into the lower rail 23. a first kick-out block (not shown) for allowing the subordinate guide 19 located on the end side in the folding direction of the guide 19 to be freely inserted into and removed from the upper rail 22;
A second kick-out block (not shown) is provided to allow the remaining slave guide 19 to be moved in and out of the upper rail 22.

Embodiment 2 above shows a ventilation type example in which the injection block 3 having the louver piece 30 is fitted to the lower end of the extrusion block 10 as shown in FIG. 8 and the fitting recesses, respectively, by fitting the opposing fitting protrusions 7 and the fitting frame 9 on the upper part of the lower injection block 3 to fit the injection block 3 having the louver pieces 30 in the vertical direction as shown in FIG. Then, multiple injection blocks 3
In this case, the panel body 2 is of a louver type having louver pieces 30 over the entire surface.

Further, the outer peripheral edge 17 of the injection block 3 is made of opaque resin, and the interior 18 surrounded by the outer peripheral edge 17 is made of transparent or semi-transparent resin, and is fitted with each of the fitting protrusions I on the upper and lower parts of the injection block 3. By inserting the mating frame 9 into the openings of the opposing cylindrical shafts 14 and the extrusion block 10, and fitting the injection block 3 between the upper and lower extrusion blocks 10 as shown in FIG. 6, a lighting type panel body 2 is formed. In this case, the injection block 3 is located at the center of the panel body 2, and the cylindrical shaft 140 portion, whose diameter is increased by the upper and lower fitting protrusions 7, is located at the center of the panel body 2. Because of its presence, the effect of preventing the hinge 15 from coming off is particularly great.

In the figure, 24 is a handle, and 25 is a lead panel.

Incidentally, since the injection block 3 is formed by injection molding, the hinge portion can also be integrally molded with the injection block 3.

In the present invention, as described above, a plurality of panel blocks are connected in the vertical direction to form a panel body, and an injection molded injection block is used as at least one panel block forming the panel body, so the extrusion molded panel block It is possible to change the vertical position of the injection block, which can take on a variety of shapes that are more complex and varied than the original, or increase or decrease the number of injection blocks connected, or even change the shape of the injection block. It is possible to form various panel bodies with various and varied appearances.
