[0038] Hereinafter, a fire shutter device according to another embodiment of the present invention will be described in detail with reference to FIGS. 4 to 6.

[0039] FIGS. 4 to 6 are drawings for explaining the configuration and advantages of a position guidance means employed in another embodiment of the present invention.

[0040] As illustrated in these drawings, the present embodiment comprises a positioning means for guiding the guide roller (230) to a correct position.

[0041] Guide rollers (230), which are one of the upper installation parts, are arranged in a pair at spaced-apart positions to guide both ends of the wire wound on the pulley unit (220).

[0042] The above positioning guide means is for positioning these guide rollers (230) in the correct position (vertically below the pulley unit (220)) of the horizontal frame part (120), and comprises a pair of elongated slits (121), positioning slits (122), and a roller bracket (310).

[0043] Each of the above-mentioned elongated slits (121) is formed at a position adjacent to the pulley unit (220) and corresponding to each guide roller (230) of the above-mentioned horizontal frame part (120), and each of the above-mentioned positioning slits (122) is formed on the opposite side with each of the above-mentioned elongated slits (121) in between.

[0044] The above-mentioned roller bracket (310) is installed on the horizontal frame portion (120) in a state where each guide roller (230) is rotatably supported, and comprises a main bracket portion (311), a pair of rotational support portions (312), and a pair of positioning pin portions (313).

[0045] The main bracket portion (311) is a part that communicates with each of the elongated slits (121) and has a passage hole (311a) formed therein through which a wire passes; the pair of rotational support portions (312) are formed extending upward from both edges of the main bracket portion (311) and are parts where the guide roller (230) is rotatably installed; and the pair of positioning pin portions (313) are each formed extending downward from both edges of the main bracket portion (311) and are parts that slide while inserted into each of the positioning slits (122).

[0046] The present embodiment having such a configuration is configured so that the guide roller (230) can be positioned at the vertical lower correct position of the pulley unit (220) coupled to the shaft member by moving the roller bracket (310), on which the guide roller (230) is rotatably installed, left and right along the positioning slit (122), thereby having the advantage of overcoming the disadvantage of product operational performance being impaired due to incorrect placement by precisely adjusting the relative position between parts.

[0047] To further maximize these advantages, this embodiment is made by including an auxiliary bracket (410) and a connecting member (510).

[0048] The above auxiliary bracket (410) comprises a pair of side connecting parts (411), a cover part (412), and a groove forming part (413).

[0049] Each of the above side connecting parts (411) is a part that is rotatably installed on the rotational support part (312), the cover part (412) is a part that is positioned across the pair of side connecting parts (411) to cover the open area between the pair of rotational support parts (312), and the groove forming part (413) is a part that forms a fitting groove between the cover part (412).

[0050] As clearly illustrated in FIG. 6, the above connecting member (510) is seated in the fitting groove of the auxiliary bracket (410) and in the fitting groove of another auxiliary bracket positioned adjacent to the auxiliary bracket (410). In the seated state, the pair of roller brackets (310) are configured to move together along the horizontal frame section (120), and in the released state, the auxiliary bracket (410) can rotate relative to the roller bracket (310).

[0051] The present embodiment having such a configuration is configured such that a pair of roller brackets (310) spaced apart from each other are moved in a mutually constrained state using an auxiliary bracket (410) and a connecting member (510), thereby preventing one roller bracket (310) from being misaligned relative to the other, and thus has the advantage of precisely guiding the movement of the wire connected to the fireproof screen to raise and lower the fireproof screen, thereby enabling precise implementation of the product's operation.

[0052] Meanwhile, the connecting member (510) comprises an insertion part (511) that is seated in the fitting groove of each auxiliary bracket (410) and a pair of pivot parts (512) that are rotatably connected to both sides of the insertion part (511).

[0053] The above pair of pivoting parts (512) are configured to be seated in the fitting groove while being placed flat relative to the insertion part (511) as in FIG. 4 and FIG. 5, and after being seated, to be rotated relative to the insertion part (511) as in FIG. 6 so as to come into contact with the pulley unit (220) placed on the upper side.

[0054] The present embodiment having such a configuration is configured so that the roller bracket (310) is positioned at the vertical lower position of the pulley unit (220) by the rotational portion (512) of the connecting member (510) contacting the pulley unit (220), thereby having the advantage of improving the efficiency of part placement and assembly by the operator.

[0055] Meanwhile, it is preferable that each pivot part (512) of the above-mentioned connecting member (510) be provided with a mating projection (512a), as clearly illustrated in FIG. 5.

[0056] That is, as shown in FIG. 5 (a), when the rotating part (512) of the connecting member (510) is positioned flat with respect to the insertion part (511), it is not possible to accurately determine whether the pulley unit (220) and the roller bracket (310) are positioned in the correct position. However, this embodiment is formed by including the mating projection (512a), so that the mating projection (512a) is inserted into the groove of the pulley unit (220) by the rotational movement of the rotating part (512) as shown in FIG. 5 (b) and FIG. 6, thereby having the advantage of being able to accurately set the relative position of the pulley unit (220) and the roller bracket (310).

[0057] Although various embodiments of the present invention have been described above, these embodiments and the drawings attached to this specification merely clearly illustrate a part of the technical concept included in the present invention. It is obvious that variations and specific embodiments that can be easily deduced by a person skilled in the art within the scope of the technical concept included in the specification and drawings of the present invention are all included within the scope of the rights of the present invention.
