Description

[Detailed description of the invention] [Industrial field of application] The present invention provides an inclined guide rail for window shutters that can be used freely in the vertical direction to close the shutter curtain and in the inclined direction to provide sunshading. It concerns the support structure.

[Problems to be solved by the prior art and invention] In general, a vertical guide rail and an inclined guide rail are provided, and the shutter curtain is used not only for opening and closing the opening but also for protruding to the outside and used as a sunshade (or eaves). There is something that has been made possible. However, in the past, these two guide rails were simply provided separately at the branching part in a state where they were simply spaced apart as shown in Japanese Utility Model Publication No. 36-25125, or
Alternatively, as shown in Japanese Utility Model Publication No. 47-11406, an inclined guide rail is integrally fixed in the middle of a vertical guide rail. However, in the former case, since the upper ends of both guide rails are installed separately and separated from each other, it is difficult to make the installation positions the same on the left and right sides, and as a result, the guide rails may be installed out of alignment. This has the disadvantage that the smooth opening and closing operation of the shutter curtain is impaired, and therefore, it cannot be put to practical use as it is. On the other hand, the latter eliminates the drawbacks of the former by installing an inclined guide rail directly on the vertical guide rail side, but the inclined guide rail is inclined and protrudes toward the outdoors, so it cannot absorb its own weight. In addition, the weight of the lowered shutter curtain is added, and this acts as a load that causes the inclined guide rail to droop. As a result, if an inclined guide rail is attached directly to a vertical guide rail, as in the latter case, it not only imposes a large load on the inclined guide rail, but also makes the inclined guide rail more robust to cope with the load that is constantly trying to sag. A new drawback arises in that a special mounting structure is required.

[Means for solving the problem] In view of the above-mentioned circumstances, the present invention was created with the aim of providing a support structure for an inclined guide rail in a window shutter that can eliminate these problems. The upper end of the vertical guide rail that guides the shutter curtain in the vertical direction and the upper end of the inclined guide rail that guides the shutter curtain in the outdoor direction are attached via a bifurcated bracket that is assembled to the magsa part side. A fitting groove for fitting and assembling the upper end of the inclined guide rail is formed in the bifurcated bracket, and the lower end of the indoor side fitting part of the inclined guide rail is positioned below the magnifying part of the fitting groove. While supporting the indoor lower end of the inclined guide rail, the outer surface of the outdoor fitting part of the inclined guide rail is in surface contact with the outdoor inner surface extending from the outdoor lower end position opposite to the indoor lower end of the fitting groove to the magsa part. The present invention is characterized in that the outdoor side surface of the fitting groove receives a load in a downward direction with the indoor fitting lower end of the inclined guide rail as a fulcrum.

With this configuration, the present invention enables the inclined guide rail to be firmly attached by using a bifurcated bracket without placing any burden on the vertical guide rail.

[Example] Next, an example of the present invention will be described based on the drawings. In the drawings, reference numeral 1 denotes a shutter case, and a winding device for winding up a shutter curtain is housed in the shutter case 1. 2 is a vertical guide rail that guides the shutter curtain in vertical directions to open and close the window; 3 is an inclined guide rail that is inclined to project outdoors at a predetermined angle with respect to the vertical guide rail 2; . Reference numeral 4 denotes a bifurcated bracket whose upper edge is formed into a crank shape when viewed from above;
The upper edge is attached to the magsa (the mounting boundary line between the shutter case 1 and the forked bracket 4), but the upper ends of both guide rails 2 and 3 butt against the forked bracket 4 as described later. It is about to be assembled.

Reference numeral 5 denotes a side frame made of, for example, C-shaped steel, which is attached to a position slightly above the lower end of the vertical guide rail 2 via a mounting bracket 13 in a substantially horizontal manner, and its tip ends at the lower end of the left and right inclined guide rail 3. is supported. Caps 8 and 9 are attached to the tip and base of the side frame 5, respectively, and between the caps 8 and 9 there is a handrail 6 curved downward in an arc shape.
A plurality of handrails a are installed in parallel to form a horizontal handrail 6. The Kasagi 8 is fixed to the tip of the side frame 5 with a T-bolt (not shown) by a T-slot 8a into which the head of the T-bolt is inserted, and into which the handrail 6a is inserted diagonally downward. A handrail mounting groove 8b is formed so that the handrail is fixed.

On the other hand, a plurality of handrails 7a are also installed between the draining board 10 provided at the lower edge of the opening and the cap 9 to form a handrail 7. The cross section of this Kasagi 9 is
It has a substantially rectangular shape with corners removed, and has a baluster hook part 9a at its lower end to which a hook 12a of a hook 12 fitted to the rear end of the baluster 6a is latched, and a lower middle part. A mounting groove 9b into which the upper end of the handrail 7a is inserted and mounted is formed in the lower base, and a T-slot 9c for mounting a T-bolt to the side frame 5 is formed in the lower base. The lower part of the handrail 7a is attached via the hook 12 to a hook 10a provided at the tip of a draining plate 10 (FIG. 6). The drain plate 10 has upper and lower flanges 1
0b and 10c are pressed against the building side and fixed with screws or the like.

The guide rails 2 and 3 are provided with shutter curtain guide grooves 2a and 3a, respectively.
Insertion grooves 2b and 3b into which a sound deadening material is inserted are formed at the leading edges of the openings of the guide grooves 2a and 3a. Further, the outer guide groove side of the upper end of the vertical guide rail 2 is cut out, and the inner guide groove side of the upper end of the inclined guide rail 3 is cut out to form cutout parts 2c and 3c, respectively, and the remaining inside of the vertical guide rail 2 is cut out. The upper end of the guide groove side 2d and the upper end of the outer guide groove side 3d of the inclined guide rail 3 are respectively bent into arcs in opposite directions to constitute upper guides 2d and 3d, respectively, which will be described later.

Further, the forked bracket 4 mentioned above to which both the guide rails 2 and 3 are connected is, as shown in FIG.
Fixed side 4 fixed to the main body side with bolts etc.
a, an inner side 4b that is bent at a substantially right angle from the fixed side 4a and faces inward of the opening; It is formed by a rail receiving side 4c bent at right angles and a guide side 4d integrally projecting from the inner side 4b. This guide side 4d has an arcuate top 4e,
Both sleeve portions 4f and 4g are set to straddle the direction of the guide grooves of the inclined guide rail 3 and the vertical guide rail 2, respectively. Furthermore, stepped portions 4h and 4i are formed between the inner side 4b and both sleeve portions 4f and 4g, and the cutout portions 2c and 3c of the guide rails 2 and 3 are fitted in abutting manner to form stepped portions 4h and 4i. The guide grooves 2a, 3a on the side of the notches 2c, 3c of the guide rails 2, 3 engage with the step portions 4h, 4i, and the inner side 4b, which is the confluence of the bifurcated bracket 4, and the sleeve portion 4
f and 4g, respectively, so that the shutter curtain can be moved up and down in exactly the same way as in the case of individual guide rails.

Both guide rails 2 and 3 are integrally attached by fitting their upper ends so that the bottom of the guide groove contacts the inner side 4b.
In this case, the inner guide groove side 2d of the vertical guide rail 2
and the outer guide groove side 3d of the inclined guide rail 3 face each other, and as a result, a bifurcated portion facing the vertical direction and the inclined direction is formed at the forked bracket 4 portion directly below the magsa, and this bifurcation In the shutter case 1 immediately above the magsa following the section, an upper guide recessed into the shutter case 1 forms a shutter guide that spreads upward. Moreover, at this time, the upper end of the inclined guide rail 3 is connected to the outdoor rail receiving side 4.
The lower end of the inclined guide rail 3 on the outdoor side is fitted into a fitting groove formed by the indoor sleeve part 4g and the step part 4f. It is supported in contact with the lower end of the fitting groove of the bracket 4 (i.e., the lower edge of the stepped portion 4i), and the upper end faces outdoors with this as the fulcrum O (that is, the lower end of the inclined guide rail 3 hangs down with the fulcrum O as the center). This load acts on the bifurcated bracket where the outer surface of the outdoor fitting part of the inclined guide rail 3 extends from the outdoor lower end position facing the fulcrum part O to the magsa part. It is configured to be received and supported in surface contact over a long range by the rail receiving sides 4c of No. 4.

In the embodiment of the present invention constructed as described above, first, the drain plate 10, which serves as the reference for the opening, and the shutter case 1 are locked and fixed to the frame. Next, after installing the vertical guide rail 2, the bifurcated bracket 4 is screwed and assembled to the vertical guide rail 2 from the back side. After that, the upper end of the inclined guide rail 3 is inserted into the forked bracket 4, and the outer surface of the inclined guide rail 3 on the outside of the upper end chamber is in surface contact with the rail receiving side 4c of the forked bracket 4 over a long range in the vertical direction. By screwing and assembling the parts, both guide rails 2 and 3 form a bifurcated bracket 4.
will be integrally fixed. Furthermore, in the embodiment, the side frame 5 is attached to the handrail 7, the hook part 12a at the lower end of the handrail 7a is hooked to the hook 10a of the draining board 10, and is rotatably engaged, and the bracket 13 is attached to the vertical guide rail. 2. Align the rear end with the specified position and fix it to the building side. Next, the hook portion 12a of the hook 12 inserted into the horizontal balustrade 6a is rotatably engaged with the balustrade hook portion 9a, and the other end of the horizontal balustrade 6a is inserted into the cap 8 and screwed with the screw 12b. The window shutter is assembled by fixing it, and assembling the side frame 5, cap 8, and inclined guide rail 3.

And guide rails 2 and 3 assembled like this
By selecting one of these and lowering the shutter curtain, you can freely use it to close the window or as a sunshade. As in the conventional case, the inclined guide rail 3
By attaching both guide rails 2 and 3 to the bifurcated brackets 4 placed directly below the magsa part of the shutter case, instead of fixing them to the vertical guide rail 2, the upper ends of both guide rails 2 and 3, In particular, the upper end of the inclined guide rail 3 that is installed later will be accurately positioned by the bifurcated bracket 4. Therefore, the load acting in the hanging direction with the lower end of the fork bracket 4 as the fulcrum O is applied to the rail receiving side 4c provided on the outdoor side of the fork bracket 4 within the range where the outer surface portion of the upper end of the inclined guide rail 3 on the outside of the room is long in the vertical direction. By making face-to-face contact with the object, it will be reliably received. Therefore, the inclined guide rail 3 is firmly attached to the bifurcated bracket 4 at its upper end, and the vertical guide rail 2 is attached to the conventional vertical guide rail 2 like the one attached to the conventional vertical guide rail 2.
Therefore, there is no problem even if the vertical guide rail 2 is a general-purpose one. Moreover, the mounting structure that allows the inclined guide rail 3 to receive the load in the direction in which it hangs down is such that the outdoor rail receiving side 4c that constitutes the rail fitting groove is used to connect the magsa part upward from the position facing the fulcrum O. Since it is sufficient to make surface contact with the outer surface of the outdoor side fitting portion of the inclined guide rail 4 over a long range in the vertical direction up to , the mounting structure does not become complicated at all.

[Operation and Effect] In summary, since the present invention is constructed as described above, in addition to the vertical guide rail, the inclined guide rail provided to guide the outdoor side has the following features:
Due to its own weight and the weight of the shutter curtain being pulled down, a load will be applied to the bifurcated bracket as it tries to hang down using the lower end of the indoor side as a fulcrum, but this load is applied to the fulcrum of the fitting groove. The outdoor outer surface of the inclined guide rail is received in surface contact with the long outdoor inner surface extending from the outdoor lower end position facing to the upper magsa part, and therefore the load is widely distributed over the fitting groove part. In this way, it will be firmly accepted and supported. As a result, the inclined guide rail is always attached to the bifurcated bracket while receiving the strong support effect of the above-mentioned distributed reception by the rail receiver.
It is possible to reliably avoid imposing an unnecessary burden on the vertical guide rail, as in the case of a conventional vertical guide rail that is directly installed, and it can be installed in a strong state that will not sag unnecessarily.
Moreover, the strong mounting structure of this inclined guide rail is such that a fitting groove is formed in the bifurcated bracket to fit the inclined guide rail, and the lower end of the fitting groove on the indoor side supports the fitting lower end of the inclined guide rail on the indoor side. It is possible to use an extremely simple structure in which the long outdoor inner surface extending from the position opposite to the support position to the direction of the magsa part above is brought into surface contact with the outdoor fitting part of the inclined guide rail and supported. The structure is simplified, assembly work on site is easy, and costs can be significantly reduced.
