[0105] In some cases, the quick-change mechanism 7500 may include an attachment retaining portion 7540. The attachment retaining portion 7540 may be configured to receive part of the extension 7400. This configuration may allow the quick-change mechanism 7500 to be securely attached to the extension 7400, which may be suspended from the track 7100.

[0106] The quick-change mechanism first part 7502 or the quick-change mechanism second part 7503, or both, may include an attachment pin 7505. In some implementations, the attachment pin 7505 may be configured for inserting into an opening of the extension 7400. This feature may provide a secure connection between the quick-change mechanism 7500 and the extension 7400.

[0107] In some cases, the quick-change mechanism 7500 may include a slot 7525. The slot 7525 may be configured to accommodate additional components, for example, magnets. The magnets may serve to bias multiple quick-change mechanisms 7500 together, for example, when no curtain attachments 7600 are suspended from the quick-change mechanisms 7500.

[0108] As discussed above, the quick-change mechanism 7500 may be designed to interact with the hanger part of the curtain attachment 7600. In some implementations, this interaction may involve the first part hanger 7632 or the second part hanger 7633 of the curtain attachment 7600. This configuration may allow for easy installation and removal of curtain segments.

[0109] FIGS. 36 and 37 depict views of the locking mechanism 7610 in locked and unlocked configurations, respectively, in accordance with embodiments. The figures show the first part 7602, second part 7603, and locking mechanism 7610 of a curtain attachment 7600. The figures also show a second part 7603of a further curtain attachment 7600. Additional components of the further curtain attachment 7600are not shown in order to allow visualization of the locking mechanism 7620 and interaction with the further curtain attachment 7600.

[0110] As discussed above, the locking mechanism 7610 may be configured to pivot between an unlocked configuration and a locked configuration. The locking mechanism tabs 7614 may be configured to extend into a second curtain attachment 7600 when in the locked configuration.

[0111] In the locked configuration, as shown in FIG. 36, the locking mechanism tabs 7614 may engage with the further curtain attachment 7600. This engagement may secure the curtain attachment 7600 and the further curtain attachment 7600together in a nested state. In some implementations, the first part 7602 of the curtain attachment 7600 may be positioned in connection with the second part 7603of the further curtain attachment 7600, with the locking mechanism tabs 7614 extending into the second part 7603. Further, as discussed above, in the locked configuration, the locking mechanism may also no longer retain the curtain attachment in the quick-change mechanism, thus allowing for removal of the curtain attachment from the quick-change mechanism for a quick change of the curtain.

[0112] Referring to these figures along with FIG. 18, in embodiments the center space 7690 is defined by a circular castellated surface having merlons or projections or upright solid portions 7697 and crenels, also known as embrasures or recesses or gaps or notches or slots 7698. The merlons have ramps 7695, 7696 (note only two of the four ramps are shown). In operation, the locking mechanism tabs 7614 (FIG. 17) are inserted into the crenels 7698 (FIG. 18). It should be noted that the tabs 7614 have a triangular shape 7615 that widens inwardly. This is so that when inserting the tabs 7614 into the crenels 7698, exact alignment is not needed and the tabs will be guided into the crenels 7698 by the taper of the triangular shape 7615. During rotation of the lever 7610 the lower surface of the tabs 7699 engages the ramps 7695, 7696, etc. on the merlons. The ramps permit the mechanical advantage of the ramp 7695, 7696 to tighten the tabs 7614 onto the merlons 7697 in a smooth and easy manner. This is an advantage because a curtain will have multiple curtain hangers such as 4, 5, 6, 7, 8, 9, 10, 11, or 12 on one curtain based upon the number of pleats in the curtain. Most commonly, 8-10 curtain hangers will be used. The use of the mechanical advantage of the lever 7610 in combination with the ramps 7695, 7696, etc. permits ease of tightening against the frictional force of four tabs times the number of curtain hangers, e.g. 40 tabs for 10 curtain hangers. It also compensates for tabs that are not exactly aligned during the rotation. The locking mechanism lever 7611 may be configured to control the transition between the locked and unlocked configurations. In some cases, applying force to the locking mechanism lever 7611 may cause the locking mechanism 7610 to pivot, moving the locking mechanism tabs 7614 into or out of engagement with the adjacent curtain attachment 7600.

[0113] FIG. 37 illustrates the unlocked configuration of the locking mechanism 7610. In this configuration, the locking mechanism tabs 7614 may be disengaged from the further curtain attachment 7600. This disengagement may allow the curtain attachment 7600 and the further curtain attachment 7600to be separated or repositioned as needed. As discussed above, in this unlocked configuration, the locking mechanism may retain the curtain attachment in the quick-change mechanism, keeping the curtain attachments, and corresponding curtain, attached to the quick-change mechanism and thereby attached to the extension, rollers, track, etc.

[0114] In some implementations, when multiple curtain attachments 7600 are in the locked configuration, the curtain attachments 7600 may form a single connected unit. This single connected unit may allow for efficient handling and manipulation of multiple curtain segments simultaneously. For example, in some cases, the single connected unit of curtain attachments 7600 may be removed from the quick-change mechanism 7500 as a single entity, potentially simplifying the process of curtain removal or replacement.

[0115] The nested configuration of the curtain attachments 7600 in the locked state may provide a compact and secure arrangement. In some cases, this nested configuration may allow for efficient storage or transportation of multiple curtain segments when not in use.

[0116] In embodiments, a curtain system may include a set of vertical extension rods 7400. The extension rods 7400 may be suspended from a track 7100 positioned at the top of the assembly.

[0117] The curtain system may also incorporate a set of quick-change mechanisms 7500. Each quick-change mechanism 7500 may be attached to a respective vertical extension rod 7400. In some cases, the quick-change mechanism 7500 may include a quick-change mechanism first part 7502 and a quick-change mechanism second part 7503 that work together to form the main structure. The quick-change mechanism 7500 may feature an attachment retaining portion 7540 configured to receive part of the extension rod 7400, allowing for secure attachment.

[0118] A set of curtain attachments 7600 may be included in the system. These curtain attachments 7600 may be designed to engage with the set of quick-change mechanisms 7500. In some implementations, the curtain attachments 7600 may be removably suspended from the quick-change mechanisms 7500 via engagement with a hanger part. This hanger part may be in the form of a first part hanger 7632, a second part hanger 7633, or both. The hanger part may interface with a quick-change mechanism hanger 7510 extending from the upper portion of the quick-change mechanism 7500.

[0119] The curtain attachments 7600 may be configured to attach to a curtain 7800. In some aspects, the curtain attachments 7600 may include features such as a nob 7640 and a corresponding opening 7642 that provide connection points for the curtain 7800. This configuration allows the curtain 7800 to be supported and manipulated through the curtain attachments 7600.

[0120] The set of curtain attachments 7600 may be designed to nest together in a locked configuration. Each curtain attachment 7600 may include a locking mechanism 7610 with components such as a locking mechanism lever 7611, a locking mechanism cap 7613, and locking mechanism tabs 7614. When engaged, the locking mechanism 7610 may allow adjacent curtain attachments 7600 to connect securely, forming a single connected unit.

[0121] In the locked configuration, the locking mechanism tabs 7614 of one curtain attachment 7600 may extend into and engage with an adjacent curtain attachment 7600. This nested arrangement may provide a compact and secure configuration for the curtain segments. The locking mechanism lever 7611 may facilitate the transition between locked and unlocked states, allowing for easy adjustment of the curtain layout.

[0122] The modular nature of this curtain hanging system, with its combination of vertical extension rods 7400, quick-change mechanisms 7500, and nestable curtain attachments 7600, may provide flexibility in installation and configuration. The system may allow for efficient installation, removal, and reconfiguration of curtain segments, potentially improving the functionality and adaptability of the curtain system in various settings.

[0123] In a further embodiment, a disposable curtain assembly may include a curtain and a set of curtain attachments. The curtain may be designed for temporary or single-use applications, providing a cost-effective solution for various settings such as healthcare facilities, temporary event spaces, or construction sites where privacy or space division is needed.

[0124] The set of curtain attachments may be configured to securely fasten to the curtain material. In some aspects, each curtain attachment may include features such as a nob and a corresponding opening that provide connection points for the curtain. This configuration may allow the curtain to be supported and manipulated through the curtain attachments.

[0125] Each curtain attachment in the set may have a locking mechanism designed to engage with another curtain attachment. The locking mechanism may include components such as a locking mechanism lever, a locking mechanism cap, and locking mechanism tabs. When activated, the locking mechanism may allow adjacent curtain attachments to connect securely to one another.

[0126] In some embodiments, the locking mechanism may be configured to pivot between an unlocked configuration and a locked configuration. In the locked configuration, the locking mechanism tabs of one curtain attachment may extend into and engage with an adjacent curtain attachment. This engagement may secure the curtain attachments together in a nested state.

[0127] The set of curtain attachments may be designed to nest together in the locked configuration. This nested arrangement may provide a compact and secure configuration for the curtain segments. In some cases, when multiple curtain attachments are in the locked configuration, they may form a single connected unit. This single connected unit may allow for efficient handling and manipulation of the curtain, for example, with the curtain attachments consolidated into a single unit.

[0128] The locking mechanism lever may be configured to control the transition between a first position and a second position, causing the locked and unlocked configuration of adjacent curtain attachments 7600. In the first position, adjacent curtain attachments 7600 are locked together and the curtain attachments 7600 are unlocked from the quick-change mechanisms 7500. Applying force to the locking mechanism lever may cause the locking mechanism to pivot to the second position, moving the locking mechanism tabs out of engagement with the adjacent curtain attachment 7600 causing them to unlock, simultaneously moving to the second position causes locking the curtain attachments to the quick-change mechanisms 7500. In the second position, the curtain may be fanned out.

[0129] In the unlocked configuration of the adjacent curtain hangers, the locking mechanism tabs may be disengaged from the adjacent curtain attachment. This disengagement may allow the curtain attachments to be separated or repositioned as needed, providing flexibility in curtain layout and configuration.

[0130] The curtain attachments may include additional features to facilitate their integration into a larger curtain system. For example, they may incorporate a hanger part, which may be in the form of a first part hanger, a second part hanger, or both. This hanger part may be designed to engage with other components of a curtain system, such as a quick-change mechanism.

[0131] The modular nature of this disposable curtain assembly, with its combination of a curtain and nestable curtain attachments, may provide flexibility in installation and configuration. The system may allow for efficient installation, removal, and reconfiguration of curtains, potentially improving the functionality and adaptability of the curtain system in various settings.

[0132] In some implementations, the nested configuration of the curtain attachments in the locked state may provide a compact and secure arrangement. This nested configuration may allow for efficient storage or transportation of the curtain assembly when not in use, which may be particularly beneficial for disposable or temporary installations.

[0133] In further embodiments, a method of removing a curtain may be provided. The method may involve a disposable curtain that includes or is attached to multiple curtain attachments. These curtain attachments may be designed to facilitate easy installation, removal, and reconfiguration of the curtain.

[0134] The method may begin with the disposable curtain in a spread state, where the curtain attachments are distributed along the length of the curtain. In this spread state, the curtain may be fully extended and functional, providing privacy or space division as needed. Respective curtain attachments may be locked to respective quick-change mechanisms such that the curtain attachments are suspended from the quick-change mechanisms and the curtain attachments and quick-change mechanisms move together.

[0135] To initiate the removal process, the method may involve transitioning the disposable curtain from the spread state to a locked state. This transition may be accomplished by bringing the curtain attachments together. As the curtain attachments are brought into proximity with one another, they may be configured to engage with each other.

[0136] The engagement of the curtain attachments may be facilitated by a locking mechanism incorporated into each curtain attachment. This locking mechanism may include components such as a locking mechanism lever, a locking mechanism cap, and locking mechanism tabs. The method may involve pivoting the locking mechanism from an unlocked configuration to a locked configuration.

[0137] In the locked configuration, the locking mechanism tabs of one curtain attachment may extend into and engage with an adjacent curtain attachment. This engagement may secure the curtain attachments together in a nested state. The locking mechanism lever may be manipulated to control the transition between the locked and unlocked configurations.

[0138] When multiple curtain attachments are brought together and their respective locking mechanisms are engaged, they may form a single curtain attachment unit. This single unit may comprise all or a subset of the curtain attachments originally spread along the curtain. The formation of this single unit may allow for efficient handling and manipulation of multiple curtain segments simultaneously.

[0139] Further, when the locking mechanisms are engaged, the locking mechanism may also no longer lock the curtain attachment to the quick-change mechanism. For example, the locking mechanism ridge may no longer retain the curtain attachment hanger in the quick-change hanger.

[0140] Once the curtain attachments are locked together as a single curtain attachment unit, the method may proceed to the removal step. The single curtain attachment unit, along with the attached curtain material, may be removed as one cohesive piece. This removal may involve disengaging the single curtain attachment unit from a support structure, such as a quick-change mechanism or a track system.

[0141] The method of removing the curtain as a single unit may offer several potential advantages. For example, it may simplify the removal process by allowing the user to handle multiple curtain attachments at once, rather than removing each segment individually. This may lead to time savings and increased efficiency in curtain management.

[0142] Additionally, removing the curtain as a single unit may help maintain the organization of the curtain. The nested configuration of the curtain attachments in the locked state may provide a compact and secure arrangement, which may be beneficial for storage or transportation of the curtain assembly when not in use.

[0143] This method may be particularly useful in settings where curtains need to be frequently changed or removed, such as healthcare facilities, temporary event spaces, or construction sites. The ability to quickly transition the curtain from a functional, spread state to a compact, removable unit may enhance the versatility and usability of the curtain system.

[0144] In some embodiments, the method may also facilitate the installation of a new curtain. A new disposable curtain with its associated curtain attachments may be prepared in the locked state as a single curtain attachment unit. This unit may then be easily attached to the support structure, after which the locking mechanisms can be disengaged to spread out the curtain attachments and deploy the curtain.

[0145] The method may thus provide a streamlined approach to curtain management, potentially improving efficiency in various settings where privacy solutions or space division are required on a temporary or changeable basis.

[0146] A number of implementations have been described. Nevertheless, it will be understood that various modifications may be made without departing from the spirit and scope of the disclosure. Accordingly, other implementations are within the scope of the following claims.
