The present invention relates generally to the field of shade systems. The present invention relates specifically to anti-ligature shade systems usable in behavioral health facilities.
In behavioral health facilities, some patients are at risk of harming themselves and will use whatever objects that may be around them to that effect. Thus, in behavioral health facilities, structures and components must be designed to substantially limit their ability to be used by patients who may wish to harm themselves. Embodiments of the present invention relate to a shade system that addresses this need in the art.
One embodiment of the invention relates to a shade system. The shade system includes a first track assembly, a second track assembly, a shade, a bottom rail, and a security box. The first track assembly includes a first track having a first interior surface defined by a first front wall, a first rear wall, a first sidewall, and two first partitions. One of the first partitions extends from the first front wall, and the other of the first partitions extends from the first rear wall. A first gap is provided between the two first partitions. The first track assembly also includes a first rod disposed within the first track such that the first rod does not contact the first interior surface. The second track assembly includes a second track having second interior surface defined by a second front wall, a second rear wall, a second sidewall, and two second partitions. One of the second partitions extends from the second front wall, and the other of the second partitions extends from the second rear wall. A second gap is provided between the second partitions. The second track assembly also includes a second rod disposed within the second track such that the second rod does not contact the second interior surface. The shade has a first outer loop wrapped around the first rod, a second outer loop wrapped around the second rod, and a bottom loop. The bottom rail is connected to a first idler end having a first loop portion around the first rod and to a second idler end having a second loop portion around the second rod. The bottom rail is disposed between the first partitions and the second partitions. The first idler end is disposed within the first track, and the second idler end is disposed within the second track. Further, the bottom loop of the shade is wrapped around the bottom rail.
Another embodiment of the invention relates to an anti-ligature shade system. The anti-ligature shade system includes a first track, a first rod disposed within the first track, a second track, and a second rod disposed within the second track. The first rod does not contact the first track, and the second rod not contact the second track. The anti-ligature shade system also includes a shade and a security box. The shade has a first outer loop wrapped around the first rod and a second outer loop wrapped around the second rod. The security box houses a system that is configured to extend and retract the shade. In the anti-ligature shade system, the first track, the second track, the first rod, and the second rod extend from a first lower end to a second upper end that is within the security box.
Another embodiment of the invention relates to a shade system. The shade system includes a first track having a first interior surface and a second track having a second interior surface. The shade system also includes a first rod disposed within the first track such that the first rod does not contact the first interior surface and a second rod disposed within the second track such that the second rod does not contact the second interior surface. Further, the shade system includes a shade having a first outer loop wrapped around the first rod, a second outer loop wrapped around the second rod, and a bottom loop wrapped around a bottom rail. The bottom rail is configured to slide upwardly and downwardly between the first track and the second track when the shade is retracted and extended.
Alternative exemplary embodiments relate to other features and combinations of features as may be generally recited in the claims.
The disclosure will become more fully understood from the following detailed description, taken in conjunction with the accompanying figures, wherein like reference numerals refer to like elements, in which:
Before turning to the figures, which illustrate the exemplary embodiments in detail, it should be understood that the present invention is not limited to the details or methodology set forth in the description or illustrated in the figures. It should also be understood that the terminology is for the purpose of description only and should not be regarded as limiting.
Generally, an anti-ligature shade system is provided. In particular, the shade system is designed such that the shade cannot be pulled from the track assemblies by a patient that may attempt to wrap the shade around his/her neck in an effort to harm himself/herself. Additionally, the shade system is prevented from being bunched up and tied with a cord, i.e., prevented from forming a tie off point, such that the patient could use the cord to inflict harm. In this regard, the shade has outer loops that wrap around rods in the track assemblies such that the shade cannot be gathered to a cinch point. Further, the track assemblies are configured to restrict access to the interior components to further thwart efforts to uncouple the components of the shade system.
Referring to the
As shown in
The first track assembly 14 is defined by a first track 30 having a generally C-shaped cross-section defined by a first front wall 32, a first rear wall 34 and a first sidewall 36 connecting the first front wall 32 to the first rear wall 34. Extending from a first interior surface 38 of the first track 30 are first partitions 40. The first idler end 26 is on an interior side of the partitions 40 while the first end 24a of the bottom rail 24 is on an exterior side of the partitions 40. One or more fasteners, such as screws 42, attach the first idler end 26 to the first end 24a of the bottom rail 24, and a first gap 44 is provided between the first partitions 40 such that screws 42 can extend from the first idler end 26 to the first end 24a of the bottom rail 24. The first gap 44 extends the length of the first track 30 so that the screws 42 (and thus the bottom rail 24) can move the length of the first track 30. Disposed within the first track 30 is a first rod 46. A first loop portion 48 of the first idler end 26 is positioned around the first rod 46. In this way, the first idler end 26 is able to travel within the first track 30 along the first rod 46.
Similarly, the second track assembly 16 is defined by a second track 50 having a generally C-shaped cross-section defined by a second front wall 52, a second rear wall 54 and a second sidewall 56 connecting the second front wall 52 to the second rear wall 54. Extending from a second interior surface 58 of the second track 50 are second partitions 60. The second idler end 28 is on an interior side of the second partitions 60 while the second end 24b of the bottom rail 24 is on an exterior side of the second partitions 60. One or more fasteners, such as screws 62, attach the second idler end 28 to the second end 24b of the bottom rail 24, and a second gap 64 is provided between the second partitions 60 such that screws 62 can extend from the second idler end 28 to the second end 24b of the bottom rail 24. The second gap 64 extends the length of the second track 50 so that the screws 62 (and thus the bottom rail 24) can move the length of the second track 50. Disposed within the second track 50 is a second rod 66. A second loop portion 68 of the second idler end 28 is positioned around the second rod 66. In this way, the second idler end 28 travels within the second track 50 along the second rod 66.
The first track assembly 14, the second track assembly 16, the bottom rail 24, the first idler end 26, and the second idler end 28 define a track system 70 as shown in the exploded view of
During assembly of the track system 70, the first rod 46 is secured in the first boss 74 of the first bottom cap 72, and the second rod 66 is secured in the second boss 84 of the second bottom cap 82. The rods 46, 66 and bottom caps 72, 82 are inserted into their respective tracks 30, 50. In embodiments, the bottom caps 72, 82 are slid into the tracks 30, 50 to create a tight frictional engagement between the bottom caps 72, 82 and the tracks 30, 50, or the bottom caps 72, 82 are snap-fit into the tracks 30, 50. In embodiments, the bottom caps 72, 82 may also be fastened to the tracks 30, 50 by inserting a screw through the tracks 30, 50 and into the strengthening ribs 76, 86 of the bottom caps 72, 82. As depicted in
As mentioned above, the idler ends 26, 28 are attached to the bottom rail 24 via screws 42, 62. As shown in
Similarly, the second idler end 28 includes a second attachment portion 104 that is arranged substantially perpendicularly to the second loop portion 68. The second attachment portion 104 includes second through holes 106 through which the screws 62 are inserted. The screws 62 engage second holes 108 in the second end 24b of the bottom rail 24. In embodiments, the second holes 108 have a predetermined depth selected such that, when the screws 62 are fully inserted into the second holes 108, the second attachment portion 104 is not brought into tight abutment with the second end 24b of the bottom rail 24. In this way, the second idler end 28 is able to loop around the second rod 66 while positioning the second idler end 28 on the interior side of the second partitions 60 and the second end 24b of the bottom rail 24 on the exterior side of the second partitions 60. In embodiments, the screws 62 are self-threading screws, and the second holes 108 are not threaded. In this way, the self-threading screws 62 cut the threads into the second holes 108 during installation. However, in other embodiments, the second holes 108 may be threaded holes.
In the embodiment shown in
As mentioned above, the shade system includes outer loops on the shade that prevent the shade from being gathered and cinched. These outer loops can be seen in the cross-sectional view of
In embodiments, the outer loops 112, 114 are a different material than shade 12. For example, the material of the shade 12 may be shade cloth, e.g., woven polyethylene or polycarbonate fibers, of various densities and the material of the outer loops 112, 114 may be polyester or a polyester blend. In other embodiments, the shade 12 is made of a single material. In such embodiments, the outer loops 112, 114 can be separately formed and attached to the shade 12, or the outer loops 112, 114 can be formed from the same section of fabric as used for the shade 12. In the latter embodiment, the fabric for the shade 12 can be folded on itself to form the outer loops 112, 114 and then welded, sewn, bonded, or otherwise fastened to itself.
The outer loops 112, 114 are wrapped around the rods 46, 66 so that, when a patient pulls on the shade, the outer loops 112, 114 pull on the rods 46, 66, which are limited in their movement by the tracks 30, 50. As can be seen in
Besides allowing for flex, the rods 46, 66 are also designed to float in their tracks 30, 50 so that movement of shade 12 is not impeded by any connections between the rods 46, 66 and the tracks 30, 50. That is, as the shade 12 is extended and retracted, the outer loops 112, 114 will move along the rods 46, 66, and connection points between the rods 46, 66 and the tracks 30, 50 would impede such movement.
As shown in
In this way, an anti-ligature shade system 10 is provided in which the shade 12 is prevented from being gathered and cinched by the outer loops 112, 114 that wrap around the rods 46, 66 in the track assemblies 14, 16. Additionally, the bottom rail 24 is connected to idler ends 26, 28 having loop portions 48, 68 around the rods 46, 66 so that the bottom rail 24 can also not be pulled from the shade system 10.
