Description

[Detailed description of the invention] This invention relates to a vertical link with a U-shaped cross section that rotatably connects the horizontal pipes of a pipe shutter. Put various modern design wings between the pipes,
Moreover, the purpose of the present invention is to provide a vertical link for a pipe shutter equipped with a new design of wings that does not interfere with winding and unwinding due to rubbing of these design wings, and does not cause any adverse effects such as an increase in the winding diameter. .

(Summary of configuration) The bottom surface and the side surfaces bent vertically on both sides in the longitudinal direction of the bottom surface are formed into a groove shape, and the upper and lower ends of the side surfaces are used as connecting portions, and one of the connecting portions is connected to the other connecting portion. In a vertical link that is narrower than the width so that it can be fitted, and further has an insertion hole into which a connecting pipe is loosely fitted to connect the upper and lower vertical links to the connecting part and to insert and fix the horizontal pipe. A designed wing is attached to the inside or side surface of the bottom surface of the vertical link, and the designed wing fits within the expected longitudinal dimension of the connecting portion, and the width of the designed wing in the vertical direction is equal to the width of the vertical link attached to the connecting portion. It is characterized by being sized to fit between the horizontal pipes.

(Example) FIG. 1 shows a pipe shutter embodying the present invention, and the pipe shutter 1 is composed of a horizontal pipe 2 and a vertical link 3.

Both sides of the pipe shutter 1 are guided by guide rails 4 (shown by imaginary lines) to open and close.

Reference numeral 5 indicates a seat plate, for example, a seat plate with angles placed back to back and integrated with bolts is used.

Figures 2 and 3 show details of the vertical links, and each vertical link 3
is formed into a groove shape by a bottom surface 3a and side surfaces 3b, 3b, which are bent vertically on both sides of the bottom surface 3a in the longitudinal direction (vertical direction in the figure).

Both upper and lower ends of the side surfaces 3b, 3b serve as connecting portions.

One of the connecting portions (the upper end in FIG. 3) narrows the width between the side surfaces, and is loosely fitted between the side surfaces of the lower end portions of the upper vertical links 3 to be connected.

The upper and lower connecting parts have insertion holes 6 and 7 into which the connecting pipe 8 is loosely fitted.
is drilled.

The connecting pipe 8 has a head 8a at one end and has an inner diameter through which the horizontal pipe 2 can be inserted.

Now, in order to connect the upper and lower vertical links 3, 3, connect the connecting pipe insertion hole 7 on the lower side of the upper vertical link 3 and the connecting pipe insertion hole 6 bored in the upper narrow part of the lower link as shown in FIG. Align them as shown and insert the connecting pipe 8.

After that, the side opposite to the head 8a may be caulked 8b.

To connect the vertical link 3 and the horizontal pipe 2 assembled in this state, the horizontal pipe 2 is inserted into the connecting pipe 8, and after drilling a hole as shown by reference numeral 9, it is positioned using a spring pin or the like (not shown).

In the present invention, designed wings of an appropriate shape are attached to the vertical link 3 of the pipe shutter as described above, as shown in FIG. 4 or FIG. 5.

The design wing 10 shown in FIG. 4 is formed symmetrically, and is made of steel, stainless steel, resin, or the like.

At the center of the design wing 10, there is a convex mounting portion 11 for attaching to the inner surface of the bottom surface 3a of the vertical link 3, ie, the bottom of the U-shaped groove, with screws, blind rivets, etc. (not shown).
11 are provided vertically in pairs, and this mounting portion 1
1 to the bottom of the U-shaped groove of the vertical link 3.

Reference numeral 12 indicates an insertion hole for a screw or blind rivet provided in the mounting portion 11, and reference numeral 13 indicates an insertion hole for a blind rivet or the like drilled in the vertical link 3.

In this case, the design wing falls within the range of the expected dimension in the longitudinal direction of the connecting portion of the vertical link 3, that is, the dimension t in the inward and outward direction of the connecting portion of the vertical link 3 in FIG.

At the same time, the vertical width of the design wing is the insertion hole 6, 7.
The dimensions are such that it fits between the upper and lower horizontal pipes 2, which are inserted into the connecting pipe 8 that is attached to the pipe.

For this reason, when opening the shutter, the design wing 10 is rolled up together with the vertical link 3, but the upper and lower design wings 10
There is no contact between the comrades, and the winding can be smoothly carried out at the winding section.

FIG. 5 shows an embodiment in which the design wings 14 are attached to both side walls of the U-shaped groove of the vertical link 3.

A mounting portion 15 is provided on the design wing 14 by being bent at right angles to the main body portion of the design wing.

To install this, place the mounting part 15 on the side surface 3b of the U-shaped groove of the vertical link 3, align the vertical link 3 with the holes 16 and 17 drilled on the design wing 14 side, and use screws or blind rivets, etc. It is supposed to stick.

In this case as well, the estimated dimension in the longitudinal direction of the connecting portion of the vertical link 3, that is, the dimension t in the longitudinal direction of the connecting portion of the vertical link 3 in FIG. 5 (FIG. 5) falls within the range.

At the same time, the width dimension of the design wing in the vertical direction is also determined by the insertion holes 6 and 7.
The dimensions are such that it fits between the upper and lower horizontal pipes 2, which are inserted into the connecting pipe 8 that is attached to the holder, and there is no problem such as contact between the design blades during winding, as in the case of the embodiment shown in Fig. 4. be.

(Effects) As described above, if the design wings are attached to the vertical link 3 in the manner shown in Fig. 4 or Fig. 5, the pipe shutter can be made to look more beautiful.

Particularly in a pipe shutter installed in a jaw room or the like, the effect can be further enhanced if a wing 10 or 14 with a design that harmonizes with the inch rear inside the shutter is selected and installed.

As described above, in the present invention, wings of any design are attached to the bottom or side walls of the U-shaped groove of the vertical link connecting the horizontal pipes of the pipe shutter, so it is possible to add a design effect in addition to the original shutter function. Suitable for use in stores, etc.

Furthermore, the dimensions of the design wing in the internal and external directions are made to fall within the expected dimensions of the vertical link in the outward and outward directions, and the dimensions in the vertical direction are made to fit between the upper and lower horizontal pipes. There are no problems with the two touching each other.
