Accordingly, unless otherwise indicated, features of the various embodiments may be additionally combined, separated, interchanged, and/or rearranged without departing from the technical concept of the present disclosure.

The use of cross-hatching and/or shading in the drawings is generally used to clarify the boundaries between adjacent components. As such, unless otherwise noted, the presence or absence of cross-hatching or shading does not convey or indicate any preference or requirement for a particular material, material property, size, proportion, commonality between the illustrated components and/or any other characteristic, attribute, property, etc., of a component. Further, in the drawings, the size and relative sizes of components may be exaggerated for clarity and/or descriptive purposes. While example embodiments may be practiced differently, the specific process sequence may be performed in a different order than that described. For example, two processes described consecutively may be performed substantially simultaneously or in reverse order to that described. In addition, like reference numerals denote like parts.

When an element is referred to as being "on" or "on," "connected to" or "coupled to" another element, it can be directly on, connected or coupled to the other element or intervening elements may be present. However, when an element is referred to as being "directly on," "directly connected to" or "directly coupled to" another element, there are no intervening elements present. For purposes of this disclosure, the term "connected" may refer to physically connected, electrically connected, and the like, with or without intervening components.

Claims (24)

1. A shade device, comprising:

a curtain surface portion;

a first shaft portion; and

a second shaft portion, the first shaft portion being parallel to the second shaft portion, a shade face portion of the shade device being wrappable around a common outer periphery of the first shaft portion and the second shaft portion;

the first shaft part and the second shaft part are connected through a linkage mechanism, so that the first shaft part and the second shaft part reset the curtain surface part based on synchronous rotation, and the first shaft part and the second shaft part synchronously rotate when being driven by the curtain surface part;

the curtain device is operable at least by gravitational pull to release the curtain surface portion in a horizontal direction, or by gravitational pull to release the curtain surface portion in a vertical direction.

2. The shade device of claim 1, further comprising a containment box to contain the shade surface, the containment box including at least one shade exit portion, the shade surface being released and/or repositioned via the shade exit portion of the containment box.

3. The shade device of claim 1, wherein the shade surface includes a first end that can be applied a gravitational or driving force pull to cause the shade surface to be released and a second end that is secured to the first shaft or the second shaft.

4. The shade device of claim 1, further comprising a retaining bracket via which the shade device can be positioned at a construction facility.

5. An isolation device for a construction installation comprising two or more fire subspaces, adjacent fire subspaces being separated by a partition having at least one hollowed-out area, comprising:

a shade device including a shade surface portion; and

an operating mechanism including a counterweight mechanism connected with a curtain face of the curtain device, the counterweight mechanism being capable of performing a releasing operation on the curtain face of the curtain device based on its own weight to cause the curtain face of the curtain device to close the hollowed-out region of the spacer;

wherein the releasing operation includes releasing the curtain surface portion in a horizontal direction and/or releasing the curtain surface portion in a vertical direction.

6. The isolation device of claim 5, wherein causing the release of the curtain face portion in the vertical direction comprises causing the release of the curtain face portion to move laterally in the vertical direction.

7. The isolation device of claim 5, wherein the operating mechanism further comprises a reversing mechanism for reversing an operating force generated by the counterweight mechanism based on its own weight to a direction suitable for releasing the curtain face portion, such that the operating force releases the curtain face portion of the curtain device.

8. The isolation device of claim 7, wherein the operating mechanism further comprises a cord portion through which the counterweight mechanism is connected with the shade face portion of the shade device.

9. The isolation device of claim 5, wherein the curtain face portion comprises stiffening ribs distributed across the curtain face portion such that the curtain face portion provides vertical support to the curtain face portion upon release.

10. The isolation device of claim 9, further comprising a track arrangement fixedly disposed on the spacer body, the track arrangement guiding movement of at least the curtain surface portion.

11. An isolation device as claimed in claim 10, wherein the number of the reinforcing ribs is plural, and the extending direction of the reinforcing ribs is perpendicular to the extending direction of the rail device.

12. An isolation device as claimed in claim 11, wherein the stiffening ribs are formed as sandwich portions of the curtain face portion.

13. An isolation device as claimed in claim 8, wherein the diverting mechanism comprises at least one fixed sheave fixed to the spacer body, the at least one fixed sheave guiding the rope portion so that the counterweight mechanism is diverted based on an operating force generated by its own weight.

14. An isolation device as claimed in claim 13, wherein the diverting mechanism further comprises at least one movable pulley or at least one movable pulley block via which the cord portion is connected with the curtain face portion of the curtain device.

15. An isolation device as claimed in any of claims 5 to 14, wherein the curtain face portion is a pleated or roller blind face portion.

16. An isolation device as claimed in any of claims 5 to 14, wherein the curtain face is a single layer curtain face or a multi-layer curtain face.

17. An isolation device as claimed in claim 5, wherein the edges of the hollowed-out regions of the spacer bodies are provided with two or more outcroppings, at least one of which is for supporting and/or holding the curtain device.

18. An isolation device as claimed in claim 17, wherein the extension is integrally formed or assembled with the spacer body.

19. An isolation device as claimed in claim 17, wherein the outtake comprises an outtake extending in a horizontal direction and/or an outtake extending in a vertical direction.

20. An isolation device as claimed in any of claims 5 to 14, wherein the curtain device is a single-axis curtain device, a dual-axis curtain device or a pleated curtain device.

21. An isolation device as claimed in any of claims 5 to 14, wherein the curtain device is as claimed in any of claims 1 to 4.

22. A parking garage comprising more than two parking spaces separated by a partition having at least one hollowed-out area, characterized in that it comprises an isolation device according to any of claims 5 to 21 for closing said hollowed-out area of said partition.

23. A building installation comprising two or more fire subspaces, adjacent two fire subspaces being separated by a partition having at least one hollowed-out area, comprising an isolation device according to any one of claims 5 to 21 for enclosing the hollowed-out area of the partition.

24. The construction equipment according to claim 23, wherein the construction equipment comprises at least an above-ground construction equipment, an underground construction equipment, a multi-story garage, an opening portion between two or more stories of a flat-story garage, a motor ramp portion, an escalator opening portion, or a stair opening portion.
