Description

[Detailed Description of the Invention] (Industrial Application Field) This invention relates to a shutter hanging base for suspending the slat curtain of a shutter.

(Prior Art) In the general structure of a lightweight shutter, a fixed shaft for winding is horizontally suspended within the shutter case at the top of the shutter, and a winding wheel is loosely fitted at multiple locations on the fixed shaft. The slats at the top of the slat curtain are suspended from the winding wheels via hanging bases, and are specifically tightened and fixed to each winding wheel with fastening bolts. The bent edge of the uppermost slat is hooked and held at the lower end of each hanger.

However, in the conventional hanger structure, a threaded hole for a fastening bolt is drilled at one location on the circumferential surface of the winding wheel, and a through hole for a fastening bolt is drilled at an opposite position of the hanger. By screwing a fastening bolt inserted through the through hole into the threaded hole, the hanger was fastened to the circumferential surface of the winding wheel.

(Problem that the invention attempts to solve) However, according to this conventional hanging structure,
Since the tightening position of the hanger with respect to the take-up wheel is fixed, this may occur if the horizontal direction goes down diagonally when assembling the slats/curtains, or if there is a difference in the slack of the slats/curtains on the left and right sides. , it is not possible to adjust or correct the hanging height of the curtains, and as a result, the curtains move up and down unsmoothly, making opening/closing operations difficult, and the sliding contact parts wear out unnecessarily. It was hot.

Therefore, the present invention makes it possible to move the hanging base by selectively finely adjusting the fastening position of the hanging base relative to the take-up wheel, thereby easily absorbing the horizontal deviation and inclination of the slat curtain. Its purpose is to provide a base for hanging ivy.

(Means for Solving the Problems) In order to achieve the object, the present invention provides a shutter suspension 5 which is screwed to the circumferential surface of the winding wheel 3 and suspends the upper edge of the slat curtain. On the lower surface of the hanging base 5 at three locations at predetermined intervals in the axial direction, there are lower protrusions 9 on one side into which the circumferential surface of the winding wheel 3 fits within the adjacent left and right intervals.
A downward protrusion consisting of a central downward protrusion 10 and the other side downward protrusion 11 is formed protrudingly, and within the interval between the one side downward protrusion 9 and the central downward protrusion 10 and the central downward protrusion 10.
A plurality of through holes 8a, 8b, 8c for screw fastening fastening bolts are provided in the spaces between the lower protrusions 11 on the other side, and a plurality of through holes in at least one of the spaces are bored in the circumferential direction. The through-holes for the screw fastening bolts drilled in the left and right intervals are characterized in that the left and right through-holes are formed at positions shifted in the circumferential direction so as to be left and right. .

(Function) Due to this structure, in the shutter suspension base of the present invention, the suspension base can be tightened against the take-up wheel by inserting a fastening bolt into the hole selected from among the multiple through holes and screwing it. You can easily fine-tune and move the landing position.

(Example) Hereinafter, the configuration of the present invention will be specifically described based on an example shown in FIGS. 1 to 7.

Suspension part 1 of a shutter equipped with a hanging base according to an embodiment
The structure of a part of the winding wheel 3 loosely fitted and attached to the fixed winding shaft 2, and the structure of a part of the winding wheel 3 that is tightened by a fastening bolt 4 surrounding the arc of the circumferential surface of the winding wheel 3. and a hanging base 5 made of an arc plate. Note that this winding wheel 3 is driven and biased in the winding direction by the stored elasticity of a torque coil spring 6 whose one end is locked to the fixed shaft 2, and fastening bolts 4 are provided at two upper and lower positions on the same line. A screw hole 3a for screwing is bored.

Next, the hanging base 5 includes a rectangular arc plate part 7 and hooked edges 7a and 7b bent at both upper and lower edges of the arc plate part 7.
, each overlapping step part 8 in the shape of an oblong rectangular dish formed with recesses in two places on the upper and lower halves of the arc plate part 7, and recesses in three places on the left, right and center of each overlapping step part 8. Molded arc-shaped lower projections 9, 10, 11, upper and lower bolt through holes 8a, 8b consisting of two horizontally long holes, upper and lower, opened on one side and between the central lower projections 9, 10; An intermediate bolt through hole 8c is formed between the center and other side lower projections 10 and 11 at an intermediate position between the upper and lower bolt through holes 8a and 8b.

In the state shown in FIGS. 2 and 3 in which the hanging base 5 formed in this way is assembled to the winding wheel 3, the center lower projection 10 and the other side lower projection 11
With the winding wheel 3 fitted in between, two fastening bolts 4 are inserted through the intermediate bolt through hole 8c and screwed into the threading hole 3a of the winding wheel 3 and tightened.

On the other hand, the hanging portion of the hook edge at the upper end of the uppermost slat 13 of the slat curtain 12 (the portion near the end in FIG. 3) is engaged and locked with the hook edge 7b at the lower end of the hanging base 5. The slat curtain 12 is suspended by the winding wheel 3.

Here, in order to adjust or correct the hanging height of the upper end of the slat curtain 12, when raising (or lowering) the height, first use the two fastening bolts 4.
After loosening and removing it, fit the winding wheel 3 between the lower protrusion 9 on one side of the hanger 5 and the lower protrusion 10 in the center, then shift it upward (or downward) and pass it through the lower left tier. All you have to do is align the hole 8b (or the upper through-hole 8a on the left side) with the threaded hole 3a of the winding wheel 3, and then screw the fastening bolt 4 into the threaded hole 3a in this state. is easy.

In the hanging base 5 of the embodiment configured in this way, the upper and lower through holes 8a, 8b on one side and the intermediate through hole 8c on the other side are opened at the wrong positions, so that there is very little damage. The hanging height can be adjusted by pitch.

In the configuration of the above-described embodiment, the suspension plate 5 other than the overlapping stepped portion 8 was configured to float above the circumferential surface of the winding wheel 3. However, instead of this, the entire surface of the suspension plate is raised above the wheel circumference. It may also be configured such that it is polymerized.

Further, although only one stage of through holes 8c on the right side of the hanging plate 5 is bored, instead of this, a plurality of arbitrary stages of through holes on the left and right sides may be provided.

(Effects of the invention) As described above, according to the shutter suspension base according to the present invention, the through holes for the fastening bolts are drilled at the opposite positions of the two rows on the left and right of the suspension base, so that the slats and
The hanging height of the curtains can be easily finely adjusted, making the opening/closing movement and opening/closing operation of the shutters smoother and easier, thereby improving the operability of the shutters.
This has the effect of improving operability and durability.
