This invention relates generally to curtains, and more specifically, to methods and systems for deployment of curtains.
Curtains, and more specifically disposable or washable curtains, have long been used, in hospitals for example, to provide privacy, room division, and to a lesser extent, to cover storage areas. Generally, these curtains are suspended from an overhead track on a ceiling for operation. For example, the curtains can be operated to substantially surround a patient's bed for privacy, and retracted at other times when privacy is not an issue.
Known curtain hanging systems include curtain engagement members, such as hooks, which are suspended from and translatable along an overhead track. The curtain engagement members allow a curtain to be suspended from the overhead track and to be moved along the path of the overhead track.
However, known curtain hanging systems suffer from functional shortcomings. For example, in some known systems, curtain engagement members are coupled to each other via linkages, such as chains, to enable a curtain to be extended by pulling on one curtain engagement member and without applying tension to the curtain itself. When the curtain engagement members are positioned proximate to each other, such linkages may become entangled with each other and/or with a curtain engagement member. Known systems may also allow a curtain and/or a curtain engagement member to become decoupled from the overhead track when a lateral and/or upward force is inadvertently applied. Furthermore, known systems may be susceptible to unintended contraction of the curtain, especially when used with a heavy and/or strongly creased curtain.
In one aspect, a curtain hanging system is provided. The system includes a curtain rod hanger and a collar. The curtain rod hanger includes an upper end having an overhead suspension member operable to couple the curtain rod hanger to a track engaging component and a lower end opposite the upper end having a curtain rod engaging member. The curtain rod hanger also includes at least one collar engaging member. The collar includes at least one curtain rod hanger engaging member that corresponds to the at least one collar engaging member of the curtain rod hanger and is operable to couple the collar to the curtain rod hanger. The collar further includes a bellows extending from the curtain rod hanger engaging member. When the collar is coupled to the curtain rod hanger, the bellows surrounds at least a portion of the curtain rod hanger.
In another aspect, a curtain hanging system is provided. The curtain hanging system includes an overhead track engaging component that includes a curtain rod hanger suspending member. The system also includes a curtain rod hanger and a collar. The curtain rod hanger includes an overhead suspension member that corresponds to the curtain rod hanger suspending member and is operable to couple the curtain rod hanger to the overhead track engaging component. The curtain rod hanger also includes at least one collar engaging member. The collar includes a bellows, which surrounds at least a portion of the curtain rod hanger when the collar is coupled to the curtain rod hanger via the collar engaging member.
In yet another aspect, a method of assembling a curtain hanging system is provided. The curtain hanging system includes a curtain rod hanger having an upper end, a lower end, and a plurality of collar engaging members at a plurality of positions between the upper end and the lower end. The method includes positioning a collar that includes a bellows about the curtain rod hanger. The curtain rod hanger is attached to a track engaging component that is translatably coupled to a track. The collar is coupled to a first collar engaging member of the plurality of collar engaging members such that the bellows extends to the track.
In an exemplary embodiment, the curtain rods 115 extend at an upper end 120 from tracked hooks 125. The upper end 120 of a curtain rod 115 may be coupled to a tracked hook 125 and/or the overhead track 110 by a curtain rod hanger 127. The tracked hooks 125 are capable of translation along the track 110 for the purpose of moving (e.g., expanding, contracting, opening, and/or closing) the curtain 105.
When the curtain 105 is contracted and/or open, the curtain rods 115 are in a position substantially adjacent one another, as further addressed below. This position may also be referred to as having the curtain 105 in a gathered position. When the curtain 105 is expanded and/or closed, the curtain rods 115 are moved from the substantially adjacent position to a configuration where they are substantially spread out along the length of the track 110. This position may also be referred to as having the curtain 105 in a deployed position.
In one embodiment, a linkage 130 extends between the curtain rods 115 and is secured to each of the curtain rods 115. As it is secured to each of the curtain rods 115, linkage 130 operates to dictate a maximum distance between the individual curtain rods 115. For example, the maximum distance may be shorter than the width of the curtain 105 between the curtain rods 115, such that when the curtain rods 115 are drawn apart, tension is applied to the linkage 130 rather than the curtain 105.
The curtain 105 may be removable. In the illustrated embodiment, curtain release mechanisms 135 engage a lower end 140 of the curtain rods 115. Curtain release mechanisms are selectively coupled to curtain engaging members 145, which are coupled to the curtain 105. Such an embodiment facilitates convenient coupling and decoupling of the curtain 105 from the curtain hanging system 100. In some embodiments, curtains are fabricated from either a disposable material or a material that may be reused after a cleaning process.
The hook 205 extends from the engaging component body 215 such that it is positioned between the channels 220. The hook 205 may be rotatable with respect to the engaging component body 215. In operation, a user moving a curtain suspended from the hook 205 effectively rolls the overhead track engaging component 200 along the channels 220 of the overhead track component 225.
In an exemplary embodiment, the overhead suspension members are provided in the form of two hook receiving apertures 410. The hook receiving apertures 410 facilitate suspending the curtain rod hanger 400 from an overhead track engaging component, such as shown in
While the curtain rod hanger 400 may include only one overhead suspension member, the inclusion of multiple overhead suspension members in the exemplary embodiment allows the curtain rod hanger to be positioned at varying vertical displacements from an overhead track. For example, each overhead suspension member may be operable to couple the curtain rod hanger 400 to an overhead track at a different vertical distance from the overhead track.
At a lower end 415 opposite the upper end 405, the curtain rod hanger 400 includes one or more curtain rod engaging members operable to couple the curtain rod hanger 400 to a substantially vertical curtain rod having a substantially hollow upper end. In an exemplary embodiment, the curtain rod engaging members are provided in the form of one or more protrusions 420, which may also be referred to as pegs.
As illustrated in
The curtain rod hanger 400 also includes a linkage engagement member 430 operable to couple the curtain rod hanger 400 to one or more linkages (shown in
The curtain rod hanger 400 further includes one or more collar engaging members in the form of protrusions 435. Collar engaging members are operable to couple the curtain rod hanger 400 to a collar, which is shown in
In the exemplary embodiment, protrusions 435 are arranged in pairs, with each protrusion 435 of a pair extending from opposite faces of the curtain rod hanger 400. For example, a first pair of protrusions 440 are included proximate to the lower end 415 of the curtain rod hanger 400.
Some embodiments facilitate coupling the collar to the curtain rod hanger 400 at varying vertical displacements from an overhead track and/or from the upper end 405. As illustrated in
The curtain rod hanger 400 includes pairs of protrusions 435 at four positions along the vertical axis 445, with the first pair of protrusions 440 positioned at a lowest vertical position and a second pair of protrusions 450 positioned at a highest vertical position. Any quantity of protrusions 435 or other collar engaging members may be spaced between the upper end 405 and the lower end 415. Further, such collar engaging members may be uniformly or non-uniformly spaced.
While the curtain rod hanger 400 is illustrated with specific types of fasteners and/or engaging members, it is contemplated that the curtain rod hanger 400 may include any form of fasteners and/or engaging members operable with the embodiments described herein. Such fasteners and/or engaging members may include, but are not limited to a hook, a protrusion, a peg, a linkage (e.g., a cable and/or a chain), a receiving aperture, a clip, a snap, a screw, a pin, a clamp, an adhesive, and/or any structure or substance operable to couple one component to another component.
The base 520 includes one or more collar engaging members operable to couple the collar 500 to the curtain rod hanger 400. The base 520 may include one or more curtain rod hanger engaging members, which may correspond to collar engaging members of the curtain rod hanger 400. In the exemplary embodiment, the curtain rod hanger engaging members are protrusion receiving apertures 525, each of which is operable to receive a protrusion 435. As shown in
In an exemplary embodiment, the at least one collar engaging member of the curtain rod hanger 400 includes at least one pair of protrusions 435 extending from the curtain rod hanger 400 in opposite directions from each other and perpendicular to the vertical axis 517. In such an embodiment, the collar 500 may include a pair of protrusion receiving apertures 525 operable to couple the collar to the curtain rod hanger by engaging the pair of protrusions 435.
In the exemplary embodiment, the collar 500 is open at both the upper end 505 and the lower end 510. A lower opening 530 at the lower end 510 facilitates sliding the collar 500 over the upper end 405 of a curtain rod hanger 400. An upper opening 535 at the upper end 505 facilitates extension of the upper end 405 of the curtain rod hanger 400 and/or a curtain rod engaging member through the upper end 505 of the collar 500.
In some embodiments, the collar 500 is configured to accommodate one or more linkages (e.g., a chain and/or a cable) extending from the curtain rod hanger 400. As shown in
A curtain rod hanger 400 and/or a collar 500 may be composed of any material or materials suitable for use with the disclosures provided herein. In an exemplary embodiment, the collar 500 is composed of resilient material (e.g., a flexible plastic), such that the bellows 515 exerts a spring force when compressed and, when removed from the compressive force, substantially returns to its original shape.
In one embodiment, the upper end 505 includes a friction surface 545 having a coefficient of static friction and/or kinetic friction that is higher than a coefficient of friction corresponding to at least a portion of the remainder of the collar 500. Such an embodiment further facilitates preventing unintended contraction of a curtain when the collar is configured such that the bellows 515 compresses the upper end 505 against an overhead track. The friction surface 545 may include a material that is different from the material used to construct at least a portion of the remainder of the collar 500. Alternatively, the friction surface 545 may include a texture (e.g., a scored, pitted, and/or pebbled texture) that produces a higher coefficient of friction than is possessed by the same material with a smooth texture.
In one embodiment, the apparatus shown in
With the collar 500 configured as shown, the bellows 515 exert an expansion force. As described above, the collar 500 is coupled to the curtain rod hanger 400. As such, the bellows 515 exert a force on the upper end 505 of the collar against a bottom surface 150 of the overhead track 110. In an exemplary embodiment, this force is substantially normal (e.g., within three or five degrees of normal) to the bottom surface 150. As a result, a frictional force sufficient to resist translation of the curtain rod hanger 400 along the overhead track 110 is generated. To enhance the frictional force, the upper end 505 of the collar 500 may include a friction surface 545 (shown in
In an alternative embodiment, the upper end 505 does not extend entirely to the bottom surface 150 or extends approximately to the bottom surface 150 but exerts a force that is insufficient to create a substantial frictional force. In one embodiment, when freestanding, the bellows 515 extends a length approximately equal to or less than a distance between the at least one collar engaging member (e.g., a protrusion 435) and the overhead track 110. In such an embodiment, the curtain rod hanger 400 is allowed to freely translate along the overhead track 110.
Some embodiments facilitate selectively configuring a frictional force for one or more curtain rod hangers in a curtain hanging system. For example, a curtain rod hanger 400/collar 500 combination may utilize at least a first collar engaging member positioned such that the corresponding bellows 515 is compressed between the overhead track 110 and the first collar engaging member. For example, such a compression of the bellows 515 may occur when the curtain rod hanger 400 is coupled to the overhead track engaging component, and the collar 500 is coupled to the first collar engaging member. A separate curtain rod hanger 400 may include one or more other collar engaging members positioned such that the corresponding bellows 515 is not compressed when the curtain rod hanger 400 is coupled to the overhead track engaging component and the collar 500 is coupled to one of the other collar engaging members.
In some embodiments, a first set of curtain rod hangers 400 is fitted with collars 500 such that the bellows 515 of the first set are compressed, and a second set of curtain rod hangers 400 is fitted with collars 500 such that the bellows 515 of the second set are not compressed. For example, the first set may include only the outside (e.g., at the ends of a curtain) curtain rod hangers 400. Such an embodiment facilitates preventing unintended contraction of the curtain while allowing free translation of the curtain rod hangers 400 in the second set.
In some embodiments, a curtain hanging system includes a plurality of curtain rod hangers 400, at least some of which are connected to each other by a linkage 130. With a collar 500 coupled to a curtain rod hanger 400, the linkage 130 may extend through the linkage channel 540 of the collar 500. During rapid movement of a curtain, the linkage 130 may be subjected to erratic forces and/or motions. Even in the presence of such uncontrolled movements, bellows 515 and linkage channel 540 facilitate preventing the linkage 130 from becoming entangled with the curtain rod hanger 400 and/or a curtain rod hanger suspending member.
The above described embodiments address several of the known problems related to the installation and removal of curtains that are attached to a ceiling mechanism. In one aspect, the ease of removal and installation of the curtain is increased as compared to known products. In another aspect, the described operation with respect to installation and removal reduces the exposure of personnel to any contaminants that may be embedded within such curtains.
