This application relates generally to a curtain assembly, and, more specifically, to a cubicle curtain assembly for use in a healthcare setting for patient privacy.
In a healthcare setting, curtains, such as cubicle curtains, can provide a private enclosure for a patient. A cubicle curtain typically hangs on hooks that are attached to a carrier. The carrier typically slides into and along a ceiling-mounted track. Following initial installation, the end of the track is capped to contain the carriers and subsequent curtain replacements are accomplished by unhooking the curtain from the hooks. Curtains are typically switched out when they become soiled and/or to reduce the spread of pathogens. However, existing cubicle curtains exhibit several drawbacks when it comes to removal and replacement.
For example, removal of a typical cubicle curtain from the hooks can be difficult and/or time consuming. A cubicle curtain typically hangs from a curtain track by a number of hooks. Each hook must be interacted with by hand so that the curtain can be removed. In some cases, a specialized hand tool may be available or a portion of the track and/or track cap may be removeable to aid in removing the curtain from the hooks. However, the specialized hand tool or removeable portion of the track and/or track cap may be easily lost or misplaced-particularly, in a fast-paced healthcare environment. Furthermore, existing track caps or closures are generally multi-piece assemblies that can be subject to misplacement of parts during a curtain change, or may require tools to assure correct installation and retention of curtains during later use. Accordingly, it would be desirable to provide a curtain (and/or curtain assembly) that can be quickly and easily removed from the curtain track without the use of specialized hand tools.
Further, hospitals, and other healthcare environments, tend to be loud, which can hinder patient rest and recuperation. Typical cubicle curtain carriers are plastic and/or metal and are conveyed along a metal track. Thus, movement of the curtain along the track can be noisy and disturb the patient. Accordingly, it would be desirable to provide a curtain (and/or curtain assembly) that significantly reduces the noise generated when conveying a curtain along a track.
Further, as mentioned above, typical cubicle curtain carriers include a hook to attach the curtain to the track. These hooks can inadvertently make their way into a laundry system when reusable curtains are cleaned and ultimately may end up lost or damaged. These hooks can snag, tear, and tangle the curtain during laundering or during installation/removal of curtains. This can particularly be an issue if the curtain includes a mesh portion. Moreover, if not lost, these hooks and/or carriers may become hazards and fall from the curtain track onto a user during installation or removal of the curtain. Accordingly, it would be desirable to provide a curtain (and/or curtain assembly) that prevents or limits damage and tangling of the curtain during installation, removal, and/or laundering. Particularly, it would be desirable to provide a hook that is integral with the curtain such that the hook can be laundered with the curtain.
Certain exemplary aspects of the invention are set forth below. It should be understood that these aspects are presented merely to provide the reader with a brief summary of certain forms the invention might take and that these aspects are not intended to limit the scope of the invention.
In one aspect of the disclosure, a curtain assembly is provided. The curtain assembly includes a curtain track having a cavity extending along a length of the curtain track. The curtain track is configured to be secured to a ceiling or a wall. The curtain assembly further includes a curtain suspended from the curtain track. The curtain is defined by a first lateral edge, a second lateral edge, a top edge, and a bottom edge. The curtain assembly further includes a plurality of hooks suspending the curtain from the curtain track. At least one hook of the plurality of hooks has a first end and a second end opposite the first end. The first end is operatively connected to the curtain adjacent the top edge of the curtain. The second end is configured to be housed within the cavity of the curtain track to slidably secure the curtain to the curtain track. The curtain assembly further includes a monolithic end cap located adjacent to and surrounding an exterior portion of an end of the curtain track. A portion of the end cap is configured to selectively transition between an open position and a closed position. In the closed position, the portion of the end cap is configured to restrict the at least one hook of the plurality of hooks from entering or exiting the cavity via the end of the curtain track. Advantageously, the monolithic construction of the end cap allows for selective, temporary access for insertion or removal of the hooks to and from the curtain track without requiring use of tools or holding separated parts, which may be particularly challenging in settings where the curtain track is installed along a high ceiling.
In one embodiment, the end cap may include an end cap body having an end wall, a first side wall, and a second side wall. The first side wall and the second side wall may be connected to and extend from the end wall. Further, the end cap body may define an inner periphery configured to face towards the curtain track and an outer periphery configured to face away from the curtain track. The inner periphery of the end cap body may be arranged in a confronting relationship with the exterior of the curtain track. The end cap may further include a flange pivotably connected to the end wall of the end cap body by a living hinge. The flange may be configured to selectively transition between the open position and the closed position. In the closed position, the flange may be configured to restrict the at least one hook of the plurality of hooks from entering or exiting the cavity via the end of the curtain track. Further, the first wall of the end cap body may include a lip portion at an end of the first wall. The second wall of the end cap body may also include a lip portion at an end of the second wall. The flange may include a first catch feature and a second catch feature. The first catch feature and the second catch feature may be located on opposing lateral edges of the flange adjacent a living hinge. In the closed position, the lip portion of the first wall may interface with the first catch feature of the flange and the lip portion of the second wall may interface with the second catch feature of the flange to selectively restrict the at least one hook of the plurality of hooks from entering or exiting the cavity via the end of the curtain track.
In another embodiment, in the closed position the flange may be substantially parallel to the end face of the curtain track. Further, the first side wall of the end cap may overlap the exterior of the curtain track for a majority of a length and a width of the first side wall. And the second side wall of the end cap may overlap the exterior of the curtain track for a majority of a length and a width of the second side wall. Further, the end wall of the end cap body may extend an end wall width between the first wall and the second wall, the flange may extend a flange width between a first lateral edge of the flange and a second lateral edge of the flange, and a width of the living hinge may be substantially coextensive with the end wall width and the flange width.
In a further embodiment, the end cap may be releasably secured to the curtain track by a transition and/or interference fit (e.g., a friction fit) between the end cap and the curtain track. Alternatively, a mechanical fastener may pass through both the curtain track and the end wall of the end cap to releasably secure the end cap to the curtain track. More specifically, the end wall of the end cap may further include an aperture and the mechanical fastener may pass through both the curtain track and the aperture of the end wall of the end cap to releasably secure the end cap to the curtain track.
In yet another embodiment, the at least one hook of the plurality of hooks may include a hook head at the second end of the at least one hook. The hook head may include a top layer and a bottom layer. The top layer and the bottom layer may be secured together to form the hook head. The at least one hook may also include a hook body extending away from the hook head. The hook body may terminate in the first end of the at least one hook.
In one embodiment, the top layer and the bottom layer of the hook head may be secured together to form a substantially Y-shaped hook head. The substantially Y-shaped hook head may be configured to avoid catching on a fastener extending into the cavity of the curtain track. Alternatively, the top layer and the bottom layer of the hook head may be secured together to form a substantially T-shaped hook head. The substantially T-shaped hook head may be configured to avoid catching on a fastener extending into the cavity of the curtain track. The hook head may include a reinforcement layer located between the top layer and the bottom layer of the hook head. The reinforcement layer may be secured to the top layer of the hook head. The reinforcement layer may be configured to add additional rigidity to the hook head. Further, the top layer and the bottom layer of the hook head may be secured together by fastening selected from the group consisting of: stitching, thermal welding, ultrasonic welding, and adhesive.
In another embodiment, the at least one hook of the plurality of hooks may be fixed to the curtain so as not to be readily removeable from the curtain. Further, the at least one hook of the plurality of hooks may be configured to be laundered with the curtain. The curtain may include a first face and a second face. The second face may be located diametrically opposite the first face. The at least one hook of the plurality of hooks may be operatively connected to at least one of the first face of the curtain and the second face of the curtain. Alternatively, the at least one hook of the plurality of hooks may operatively connected to both of the first face of the curtain and the second face of the curtain.
In a further embodiment, the at least one hook of the plurality of hooks may be constructed of a textile material. Further, the at least one hook of the plurality of hooks may be constructed so as to form a single contiguous piece of textile material. Alternatively or additionally, the at least one hook of the plurality of hooks may be constructed of a single continuous piece of textile material. Further, the textile material may be selected from the group consisting of: nylon, polyester, cotton, and polypropylene. The at least one hook of the plurality of hooks may be configured to change a material property when laundered and/or heated such that a pull force required to pull the at least one hook through a curtain track opening increases after the at least one hook is laundered and/or heated. By forming the plurality of hooks with one or more of the features as set forth above, the curtain assembly can operate with a significantly reduced movement volume as compared to conventional designs, thereby increasing patient satisfaction and comfort in this setting. Moreover, the integrated design of the hooks with the curtain allows for quicker and simpler replacement and installation actions with fewer parts to assemble and less likelihood of losing elements of the assembly (while assuring that the correct number of hooks or hangar elements is always connected to a curtain placed at the curtain track).
In one embodiment, the curtain may include curtain fasteners located adjacent the first lateral edge and located adjacent the second lateral edge of the curtain. The curtain fasteners may be configured to selectively secure the curtain to a neighboring curtain. Further, the curtain may include curtain fasteners located adjacent the first lateral edge and located adjacent the second lateral edge of the curtain. Additionally or alternatively, the curtain fasteners located adjacent the first lateral edge may be on the second face of the curtain and the curtain fasteners located adjacent the second lateral edge may be on the first face of the curtain. The curtain fasteners may be configured to selectively secure the curtain to a neighboring curtain.
In another aspect of the disclosure, a curtain assembly is provided. The curtain assembly includes a curtain track having a cavity extending along a length of the curtain track. The curtain track is configured to be secured to a ceiling or a wall. The curtain assembly further includes a curtain suspended from the curtain track. The curtain is defined by a first lateral edge, a second lateral edge, a top edge, and a bottom edge. The curtain assembly further includes a plurality of hooks suspending the curtain from the curtain track. At least one hook of the plurality of hooks having a first end and a second end opposite the first end. The first end is operatively connected to the curtain adjacent the top edge of the curtain. The second end is configured to be housed within the cavity of the curtain track to slidably secure the curtain to the curtain track. The at least one hook is configured to be laundered with the curtain. The curtain assembly further includes an end cap located adjacent to and surrounding an exterior portion of an end of the curtain track. A portion of the end cap is configured to selectively transition between an open position and a closed position. In the closed position, the portion of the end cap is configured to restrict the at least one hook of the plurality of hooks from entering or exiting the cavity via the end of the curtain track.
In another aspect of the disclosure, a method of using a curtain assembly is provided. The method includes providing a curtain assembly including a curtain and a plurality of hooks. The plurality of hooks are operatively connected to the curtain adjacent a top edge of the curtain. The method further includes inserting at least one hook of the plurality of hooks into a cavity of the curtain track. The cavity is configured for receiving the at least one hook of the plurality of hooks. The curtain track further includes a monolithic end cap located adjacent to and surrounding an exterior portion of an end of the curtain track. The method further includes closing the end cap to restrict the at least one hook of the plurality of hooks from exiting the cavity via the end of the curtain track.
In one embodiment, the method may further include opening the end cap to allow the at least one hook of the plurality of hooks to enter or exit the cavity of the curtain track. The method may further include removing the at least one hook of the plurality of hooks from the curtain track. Further, the step of closing the end cap may include mating one or more lip portions of a body of the end cap with one or more catch features of a flange of the end cap.
In another embodiment, the at least one hook of the plurality of hooks may be constructed of a textile material. The method may further include sliding the at least one hook along the curtain track and producing a peak noise of less than 65 dB. Further, the method may further include laundering the curtain assembly with the plurality of hooks operatively connected to the curtain. The method may further include laundering and/or heating the at least one hook of the plurality of hooks. Laundering the at least one hook may change a material property of the at least one hook and may increase a pull force required to pull the at least one hook through a curtain track opening. For example, the pull force required to pull the laundered at least one hook through a curtain track opening may be greater than 40 lbs. The integrated nature of the hooks and the curtain helps prevent any hazards of hangar hardware falling from the track onto users or patients during installation or replacement of a curtain.
In a further embodiment, the at least one hook of the plurality of hooks may be pulled through the curtain track opening by a pull force on the at least one hook of greater than a force of gravity on the curtain assembly. Alternatively, the at least one hook of the plurality of hooks may be pulled through a curtain track opening by a pull force on the at least one hook of greater than 5 lbs. Alternatively, the at least one hook of the plurality of hooks may be pulled through a curtain track opening by a pull force on the at least one hook of greater than 10 lbs. Alternatively, the at least one hook of the plurality of hooks may be pulled through a curtain track opening by a pull force on the at least one hook of greater than 50 lbs.
It will be understood that the various embodiments and aspects described above can be combined in any combination or sub-combination without departing from the scope of this disclosure.

The curtain 14 includes a first lateral edge 24 and a second lateral edge 26. The distance between the first lateral edge 24 and the second lateral edge 26 defines a width of the curtain 14. Similarly, the curtain 14 includes a top edge 28 and a bottom edge 30. The distance between the top edge 28 and the bottom edge 30 defines a height of the curtain 14. The curtain 14 is bound and defined by the first lateral edge 24, the second lateral edge 26, the top edge 28, and the bottom edge 30. Further, the curtain 14 may include one or more panels. For example, in the depicted embodiment, the curtain 14 includes a top mesh panel and a bottom textile panel. The panels may be joined by releasable fasteners (e.g., buttons, hook and loop fastener, Block Tapey® (commercially available from Morito Co., Ltd. of Osaka, Japan, for example), etc.) or by more permanent fastening (e.g., stitching/sewing, thermal welding, ultrasonic welding, adhesive, etc.), for example. The top mesh panel may be included in order to satisfy the NFPA701 fire code, for example, that could require an open area of at least 70% along the top 18 inches of a curtain. The bottom textile panel could be made of any suitable textile material such as a woven polyester fabric or a nonwoven (such that it is selected from a set of materials that is launderable at practical conditions) or other suitable material. Particularly, the material of the bottom textile panel may be a woven, non-woven, knitted, braided, or other suitable textile material or combination thereof and any number of suitable fibers or yarns, e.g., all-natural or synthetic fibers, or a blend or combination of natural and synthetic fibers and yarns may be employed. It should be understood that the curtain 14 may include more or fewer panels than are shown. Further, it should be understood that, the panel or panels of the curtain 14 may be made of suitable alternative materials.

A plurality of curtain hooks 16, connected to and spaced at intervals along a top edge 28 of the curtain 14, suspend the curtain 14 from the curtain track 12. For example, a curtain hook 16 may be placed approximately every 11 inches along the top edge 28 of the curtain 14, starting at or near to the first lateral edge 24 or the second lateral edge 26 of the curtain 14. Each curtain hook 16 includes a first end 38 and a second end 40, the second end 40 located opposite the first end 38. The first end 38 of the curtain hook 16 is operatively connected to the curtain 14 adjacent the top edge 28 of the curtain 14. In the depicted embodiment, the curtain hook 16 is sewn (or otherwise attached) to the curtain 14 at the first end 38 of the curtain hook 16 so as to permanently fix the curtain hook 16 to the curtain 14. Advantageously, the curtain hooks 16 of this disclosure can be laundered with the curtain 14. Such at least saves a user from having to painstakingly remove the curtain hooks 16 from the curtain 14 before laundering the curtain 14 and then replace those same curtain hooks 16 back onto the curtain 14 after laundering the curtain 14. However, it is to be understood that the curtain 14 may be alternatively secured to the curtain 14. For example, the curtain hook 16 may be releasably secured to the curtain 14 by a fastener (e.g., hook and loop fastener, snap button(s), Block Tapey®, or a similar fastener) at the first end 38, for example. As will be described in greater detail below, the second end 40 of the curtain hook 16 is configured to interface with the curtain track 12 to slidably secure the curtain 14 to the curtain track 12. Advantageously, the curtain hooks 16 of this disclosure are also configured to generate less noise when conveying along the curtain track 12. Such is beneficial at least to patient wellbeing and recovery in healthcare settings where cubicle curtains are often used.

The hook head 42 generally features a top layer 44 and a bottom layer 46. The top layer 44 and the bottom layer 46 are secured together to form the hook head 42. The top layer 44 and the bottom layer 46 of the hook head 42 may be secured together by various fastening means. In the depicted embodiment, the top layer 44 and the bottom layer 46 are secured by stitching. The stitches closest to each lateral edge of the hook head 42 may be approximately 0.625 inches apart from each other. The top layer 44 and the bottom layer 46 may be alternatively fastened together by bar tacking, thermal welding, ultrasonic welding, or adhesive, for example. It should be understood that other fastening elements are possible.
With continued reference to
The T-shaped hook head 42 is supported by a reinforcement layer 48 located between the top layer 44 and the bottom layer 46 of the hook head 42. The reinforcement layer 48 is secured to the top layer 44 of the hook head 42. In the depicted embodiment, the reinforcement layer 48 is secured by stitching. The stitching may be located approximately halfway between the stitching that secures the top layer 44 to the bottom layer 46. Alternatively, the reinforcement layer 48 may be secured to the top layer 44 by bar tacking, thermal welding, ultrasonic welding, or adhesive, for example. It should be understood that other fastening means are possible. The reinforcement layer 48 may be made of the same material as the rest of the curtain hook 16 or, alternatively, the reinforcement layer 48 may be a different, suitable material. For example, the reinforcement layer 48 may be rigid plastic, Block Tapey®, or another suitable material. Additionally, it should be understood that a T-shaped hook head 42 could be formed with or without the reinforcement layer 48. However, the reinforcement layer 48 adds additional rigidity and structure to the hook head 42.
With continued reference to
The curtain hook 16 may be constructed of a textile material. Specifically, the curtain hook 16 may be constructed from a textile material such as nylon or polyester. The curtain hook 16 could alternatively be made of cotton or polypropylene, for example, or another suitable material. The material that the curtain hook 16 is constructed may be suitable to withstand one or more industrial laundering cycles. The material may be a woven, non-woven, knitted, braided, or other suitable textile material or combination thereof and any number of suitable fibers or yarns, e.g., all-natural or synthetic fibers, or a blend or combination of natural and synthetic fibers and yarns may be employed. The thickness of the material used to form the curtain hook 16 may be between 1.8 mm and 2.2 mm. Particularly, the thickness of the material may be 2.0 mm. The width of the curtain hook 16 may be 17 mm. In an alternative embodiment, the width of the curtain hook 16 may be 38 mm.
With continued reference to
Regardless of the particular material (or materials) of the curtain hook 16, the curtain hook 16 may be constructed so as to form a single contiguous (e.g., unitary or monolithic) piece as opposed to known curtain hooks and/or carriers which are frequently two or more separate pieces. Advantageously, a single piece construction reduces the complexity of the curtain hook 16 and minimizes the chance for a part to go missing during removal of the curtain 14 and/or curtain hooks 16 from the curtain track 12. Further, the curtain hook 16 may be constructed of a single continuous piece of material. Such is shown in

The end cap 18 generally includes an end cap body 56. The end cap body 56 includes an end wall 58, a first side wall 60, and a second side wall 62. The first side wall 60 and the second side wall 62 are connected to and extend generally in the same direction from the end wall 58. The end wall width 63 is defined by a distance between the first side wall 60 and the second side wall 62 along a surface of the end wall 58. In the depicted embodiment, the first side wall 60 and the second side wall 62 extend perpendicularly (or, at least, substantially perpendicularly) from the end wall 58; however, it should be understood that the first side wall 60 and the second side wall 62 could extend from the end wall 58 at oblique angles, respectively, to the end wall 58, for example, without departing from the inventive aspects of this disclosure. The end cap body 56 defines an inner periphery 64 and an outer periphery 66 of the end cap body 56. The inner periphery 64 of the end cap body 56 is configured to face towards the curtain track 12 when the end cap 18 is installed on the curtain track 12. More specifically, the inner periphery 64 may be arranged in a confronting relationship with the exterior of the curtain track 12. The outer periphery 66 of the end cap body 56 is configured to face away from the curtain track 12 when the end cap 18 is installed on the curtain track 12.
With continued reference to
In the depicted embodiment, the flange 68 is pivotally connected to the end cap body 56 by a living hinge 76. The living hinge 76 is formed as an integral part of the end cap 18 such that the end cap body 56 and the flange 68 are pivotally connected without need for an additional part which would need to be separately installed onto the end cap 18. Advantageously, the living hinge 76 feature allows for the end cap 18 to be manufactured as a single piece of unitary construction, e.g., as a monolithic construction. Such formation at least facilitates efficient manufacturing. No additional assembly of the end cap 18 is required. Further, the inclusion of the living hinge 76 allows for the entirety of the end cap 18 to be made of the same material. Such at least further facilitates efficient manufacturing. In the depicted embodiment, the living hinge width 78 is substantially coextensive with the end wall width 63 and the flange width 70. However, it should be understood that the living hinge width 78 may vary (e.g., be shorter or longer than is depicted) without departing from the inventive aspects of this disclosure.
With continued reference to
The end cap body 56 may also include a fastener aperture 84. The fastener aperture 84 may be a molded feature introduced during manufacture or may be a feature added after manufacture. In depicted embodiment, the end cap body 56 includes a single fastener aperture 84 located in approximately the middle and center of the end wall 58 of the end cap body 56. It should be understood that, in alternative embodiments, the end cap body 56 may include more or fewer fastener apertures 84 than is shown. For example, the end cap body 56 may include no fastener aperture 84 and the end cap 18 may instead be held in place at the end of the curtain track 12 by a transition and/or interference and/or friction fit. Further, it should be understood that the more or fewer fastener apertures 84 could be alternatively located on the end cap body 56. For example, the fastener aperture 84 could be located on a first or second side wall 60, 62 of the end cap body 56 or in a location other than the middle and center of the end wall 58.

In a further alternative embodiment of the curtain hook 16, the curtain hook 16 may include a connector tab operatively connected to the hook body 50 and extending in a direction transverse to the hook body 50. The connector tab may feature one or more fasteners such that connector tabs of neighboring curtain hooks 16 may be connected to each other (or to the hook body 50 of the curtain hook 16) via the fasteners. The fastener may be hook and loop fastener, snap button(s), Block Tapey®, or a similar fastener. Such connecting of the curtain hooks 16 by the connector tabs may facilitate faster installation of the curtain hooks 16 into the curtain track 12. In addition to or in lieu of the connector tabs, the curtain hooks 16 (and, particularly the hook body 50) may include a tunnel for inserting a rod or baton through such that the curtain hooks 16 could be bunched up to facilitate faster installation of the curtain hooks 16 into the curtain track 12. Such connection and/or alignment features, while not shown in these Figures, will be understood to be positioned anywhere along the length of the hook body 50 depending on the preferences of the end user of the curtain assembly 10.

Regardless of the particular form of the hook head 42, the pull force required to pull the curtain hook 16 through the curtain track opening 90 will be greater than the force of gravity on the curtain assembly 10. In other words, the curtain hooks 16 are configured such that it will require more than just the weight of the curtain 14 itself (and the curtain hooks 16) to pull the curtain hooks 16 from the curtain track 12 through the curtain track opening 90, such is shown in Table 1 below, for example. For all of Tables 1, 2, and 3 the pull out force was determined using an automated tensile tester. The curtain hook 16 was placed into a curtain track 12 with the curtain track opening 90 facing upwards. The curtain hook 16 was then pulled upwards at a standardized rate until the curtain hook 16 exited the curtain track 12 through the curtain opening 90.
In one embodiment, pulling the curtain hook 16 through the curtain track opening 90 may require a pull force of at least 5 pounds. A relatively low pull force, such as 5 pounds, may be suitable for a behavioral health healthcare environment, for example. In an alternative embodiment, pulling the curtain hook 16 through the curtain track opening 90 may require a pull force of at least 10 pounds. In a further alternative embodiment, pulling the curtain hook 16 through the curtain track opening 90 may require a pull force of at least 15 pounds. In a further alternative embodiment, pulling the curtain hook 16 through the curtain track opening 90 may require a pull force of at least 20 pounds. In a further alternative embodiment, pulling the curtain hook 16 through the curtain track opening 90 may require a pull force of at least 45 pounds. In a further alternative embodiment, pulling the curtain hook 16 through the curtain track opening 90 may require a pull force of at least 50 pounds. In a further alternative embodiment, pulling the curtain hook 16 through the curtain track opening 90 may require a pull force of at least 70 pounds.
With continued reference to
For one nylon, Y-shaped curtain hook 16 tested, prior to laundering and drying the curtain hook 16 required 6 pounds of pull force to pull the curtain hook 16 through the curtain track opening 90. After one industrial laundering cycle (with the dryer at 160° F.), the required pull force was 20 pounds. Further, successive launderings and/or heatings may further increase the pull force required to pull the curtain hook 16 through the curtain track opening 90. After two industrial laundering cycles, the required pull force was 22 pounds. After three industrial laundering cycles, the required pull force was 30 pounds. After four industrial laundering cycles, the required pull force was 40 pounds. After five industrial laundering cycles, the required pull force was 45 pounds.
