Description
~26038~) ,i 1 -- 1 This invention relates generally to ceiling tracks for use with travelling curtains such as are found in hos-pital cubicle track systems for establishing privacy around the bed of a patient.
In the past, it has been necessary to install and remove the curtains which aré suspended from the ceiling track for traverse therein by securing the top edge o the curtain at a number of polnts to carriers which are dis-posed within the tr~ck. 'rhis is a time consuming process, and~ more significantly, it requires that the person doing the installing or removing of the curtain have access to the connection points between the curtain and the carriers, which are located at the ceiling level. This requires the -use of ladders and is a c~nbersome and sometimes dangerous procedure.
The ceiling track according to the invention elimi-nates the problems by providing a hinged terminal section incorporating a latch at the free end of the hinged section to secure the track end to the ceiling, the latch being releasable from floor level to allow the hinged section to pivot downward and thereby allow the curtain to be pulled down out of the track on its carriers for easy removal.
Similarly, a curtain may be loaded into the track on its carriers, pulled along up into the track, and then -the system may be restored to operation by pivoting the hingec track section upward into latching engagement in its operative ceiling affixed position. Alternatively, with the track in its downward pivoted position, the curtain may be connected to and disconnected from the curtain car-riers in the track without: removing the curtain carriersfrom the track~
It is a primary object of the invention to provide a novel hinged ceiling track structure including a track section having a free end latchable to an above-lying sup-porting surface.
-i26038g~
1 Another object of the invention is to provide a novel hinged ceiling track structure as aforesaid in which the latching structure for the track end is unlatchable and latchable from floor level to allow the hinged section to pivot downward for installation and removal o~ track carried articles, such as cubicle curtains and equipment hangers.
A further object of the invention is to provide a novel hinged ceiling track structure as aforesaid in which the latching structure is in two sections, one of which is fixedly secured to the enc of the track and the other of which is fixedly secured to the above lying support sur-face, the two latchable sections being operable from floor level by insertion of an actuating wand.
Yet another object of the invention is to provide a novel latching mechanism which incorporates a double latch for safety purposes, each latch being independent of the other, but both latches being simultaneously actu-atable to latch and unlatch the latching mechanism.
The foregoing and other objects of the invention will become clear from a reading of the following speci-fication in conjunction with an examination of the appended drawings, wherein:

. .
In the several figures, like elements are denoted - by like reference characters.
. Considering first Figures l and 2, there is seen a ceiling track structure including a hinged track section designated generally as 10 connected to a track section 11 by means of a hinged structure designated generally as 12.
One end of the hinged track section 10 is fixed to one hal-section of the hinge 12, designated as 13, while the other half of the hinge, designated as 14 is fixed to the : track section 11. This hinge operates in a normal and usual fashion to allow the hinged track section 10 to be ~L26038~
1 pivoted upward against the above lying ceiling 15, or pivoted downward as shown in the phantom line outline 10' into positionfor installing or removing the cubicle curtain 16 which moves within the track on its carriers ].7. At the free end of the hinged track section 10 is a track latching mechanism designated generally as 18 which is operated by an actuating wand 19, the latching mechanism having a portion fixed to the ceiling and a portion carried at the end of the track 10, the two portions being detach-ably latchable to one another to secure and release thehinged track section 10.
Referring now to Figures 3 through 6 for details of the latching mechanism 18, there is seen a five part latching mechanism in whi-h three parts are fixedly secured to the ceiling 15 and two parts are fixedly secured to the end of the hinged track s~ction 10. The portion of the latching mechanism affixe~ to the ceiling 15 includes the latching plate 20 to which is pivotally secured by means of a pivot pin 21, a generally Lrshaped resilient catch 22.
The latching plate 20 is held to the ceiling by means of screws, not shown in Figure 3,which are projected through the apertures 23 to anchor the plate 20 to the ceiling 15 as best seen in Figure 4, the anchor screw being shown as 24. The screw 24 is only representational, in some cases it being necessary to use other types of fastenings such as toggle bolts.
The part of the track latching mechanism 18 which is secured to the free end of the hinged track section 10 I includes a catch pin channel plate 25 and a cover shell 26, - 30 both of which are fixedly secured to the end of the hinged track section 10 by means of machine screws 27 projected through apertures 28 and ~9. The actuating wand 19, al-though shown in operative position in Figure 1, is not physically fixed to the track latching mechanism 18, but is an insertable and removable device, as appears from ~()3~
1 the showing of Figure 3.
The resilient L-shaped catch 22 has a generally horizontally disposed leg 30, near the end of which is formed an aperture 31, and has a generally vertically dis~
posed leg 32 toward the lower end of which is formed an upwardly sloped shelf 33. The catch pin channel plate 25 with which the L-shaped resilient catch 22 interengages, as shown in Figure 4, is formed with a bottom wall 34 ha~ing therethrough a circular aperture 35, and having projected downward from the free end of the bo-ttom wall and at an angle thereto a pair of projections 36 which are adapted to seat upon the shelf 33 of the resilient catch 22, as best seen in Figure 4. ~lso extending upward from the bottom wall 34 of the catch pin channel plate 25 are 'a pair of side walls 37, and a catch pin 38 having a hori zontal slot 39. The head of t~he catch pin 38 is adapted to be projected upward through the aperture 31 in the gen--erally horizontal leg 30 of the resilient catch 22 so that:
the end of the leg 30 catches within the horizontal slot :39 when the latch is in its latched position as shown in Fig-ure 4, this interengagement being released when the latch ~` is in its unlatched position as shown in Figure 7 so that the catch pin 38 will be enabled to slip downward out through the aperture 31 and disengage from the resilient catch 22.
The actuating wand 19 has a long handle 40 sur-mounted by a hinge 41, the two halves of which are fric-tionally engaged with one another by means of an adjust-able compression washer 42, the pressure exerted by the compression washer 42 being controlled by the adjusting screw 43. The upper section 44 of the hinge 41 is sur-mounted by a short extension 45 at the upper end of which is formed a circular cam 46 which is itself surmounted by a circular guide end post 47 which is projectable upward through the circular aperture 35 in the catch pin channel ~2t~03~
1 plate 25 when the actuating wand 19 is inserted upward through the aperture 48 in the cover shell 26 to actuate the latch mechanism.
Referring now specifically to Figures 4, 5 and 6, the latch mechanism is sho~m in its latched position so that the track 10 is securely latched to the ceiling by means of the latching plate 20 which is secured to the ceiling. As best seen in Figure 4, in the latched condi-tion, the head of the catch pin 3~ is projected through the circular aperture 49 in the latching plate 20 and the aperture 31 in the horizontal leg 30 of the resilient catch 22, and at the same time the projections 36 which extend from the end of the bottom wall 34 of channel plat~
25 are seated downward upon the shelf 33 formed on the 'vertical leg 32 of the resilient catch 22. In this way there is in effect a double latch.either of which is suf-ficient to maintain the l~tching engagement of the mechan-ism. The actuating wand 19 is shown with its working end inserted into the latch mechanism by projection upward through the circular aperture 48 in the cover shell 26 and aperture 35 in the channel plate 25, but before being actuated to unlatch the latching mechanism. If the actu-ating wand 19 were removed from Figure 4, the remainder of the figure would stay exactly as illustrated.
Consider now Figures 7 through 9 for an understand~
ing of the manner of unlatching the latch mechanism. Fig~
ure 7 illustrates the condition where the actuating wand L9 has been rotated 180 so that the circular cam 46 has later-ally pressed against the side edge of the shelf 33 on the vertical leg 32 of the resilient catch 22 and has caused the leg 32 to pivot outward through the open end 50 of the cover shell 26 by rotation around the pivot pin 21. This causes the projections 36 of the channel plate 25 to slip off of the upper surface of the shelf 33 and thereby be unlatched. Simultaneously, as the leg 32 of the resilient -126~3~(3 1 catch 22 pivots outward, the generally horizontal leg 30 of the resilient catch 22 slides to the left so that the end of the horizontal leg 30 moves sufficiently to dis-engage from the horizontal slot 39 in the catch pin 38.
~ith the catch pin 38 disengaged, it is able to move down-ward through the aperture 49 in the latching plate 20 so that the entire track section 10 and those portions of the latch mechanism secured thereto can swing downward away from the latching plate 20 into the phantom line position shown in Figure 1. A cubicle curtain can, for example, then be replaced, or some other article such as an I.V. carrier may be inserted or removed.
It should be noted that the actuating wand 19 is held captive within the ccver shell 26 and will remain that way unless the actuating wand is rotated an additional 180 to allow the circular cam 46 t~ register with the aperture 48 in the cover shell and thereby be removable.
The mechanism is relatched in the same way that it was unlatched. With the wand 19 in position as shown in Figure 7, the pivotable track section 10 is swung up-ward so that the upper edg~ of the projections 36 first engage with the bottom of the shelf 33 and drive the leg 32 outward into the position shown in Figure 7 while simultaneously moving the ~perture 31 into registry with the aperture 49 so that the catch pin 38 can easily project upward therethrough. Nith the track held in the position as shown in Figure 7 supported by the actuating wand 19J
the wand 19 is then rotated 180 so that it assumes the position in Figure 4, thereby relatching the mechanism by re-establishing the int~rlatched conditions shown in Figure 4. The actuating wand may then be removed and the mechanism is secure.
Having now described the invention in connection with a particularly illustrated embodiment thereof, it will be appreciated that modifications and variations of ~26~3~
1 the invention may now naturally occur from time to time to those persons normally skilled in the art without de-parting from the essentia scope or spirit of the inven-tion, and accordingly it is intended to claim the inven-tion broadly as well as specifically as indicated by theappended claims.

In the several figures, like elements are denoted - by like reference characters.
. Considering first Figures l and 2, there is seen a ceiling track structure including a hinged track section designated generally as 10 connected to a track section 11 by means of a hinged structure designated generally as 12.
One end of the hinged track section 10 is fixed to one hal-section of the hinge 12, designated as 13, while the other half of the hinge, designated as 14 is fixed to the : track section 11. This hinge operates in a normal and usual fashion to allow the hinged track section 10 to be ~L26038~
1 pivoted upward against the above lying ceiling 15, or pivoted downward as shown in the phantom line outline 10' into positionfor installing or removing the cubicle curtain 16 which moves within the track on its carriers ].7. At the free end of the hinged track section 10 is a track latching mechanism designated generally as 18 which is operated by an actuating wand 19, the latching mechanism having a portion fixed to the ceiling and a portion carried at the end of the track 10, the two portions being detach-ably latchable to one another to secure and release thehinged track section 10.
Referring now to Figures 3 through 6 for details of the latching mechanism 18, there is seen a five part latching mechanism in whi-h three parts are fixedly secured to the ceiling 15 and two parts are fixedly secured to the end of the hinged track s~ction 10. The portion of the latching mechanism affixe~ to the ceiling 15 includes the latching plate 20 to which is pivotally secured by means of a pivot pin 21, a generally Lrshaped resilient catch 22.
The latching plate 20 is held to the ceiling by means of screws, not shown in Figure 3,which are projected through the apertures 23 to anchor the plate 20 to the ceiling 15 as best seen in Figure 4, the anchor screw being shown as 24. The screw 24 is only representational, in some cases it being necessary to use other types of fastenings such as toggle bolts.
The part of the track latching mechanism 18 which is secured to the free end of the hinged track section 10 I includes a catch pin channel plate 25 and a cover shell 26, - 30 both of which are fixedly secured to the end of the hinged track section 10 by means of machine screws 27 projected through apertures 28 and ~9. The actuating wand 19, al-though shown in operative position in Figure 1, is not physically fixed to the track latching mechanism 18, but is an insertable and removable device, as appears from ~()3~
1 the showing of Figure 3.
The resilient L-shaped catch 22 has a generally horizontally disposed leg 30, near the end of which is formed an aperture 31, and has a generally vertically dis~
posed leg 32 toward the lower end of which is formed an upwardly sloped shelf 33. The catch pin channel plate 25 with which the L-shaped resilient catch 22 interengages, as shown in Figure 4, is formed with a bottom wall 34 ha~ing therethrough a circular aperture 35, and having projected downward from the free end of the bo-ttom wall and at an angle thereto a pair of projections 36 which are adapted to seat upon the shelf 33 of the resilient catch 22, as best seen in Figure 4. ~lso extending upward from the bottom wall 34 of the catch pin channel plate 25 are 'a pair of side walls 37, and a catch pin 38 having a hori zontal slot 39. The head of t~he catch pin 38 is adapted to be projected upward through the aperture 31 in the gen--erally horizontal leg 30 of the resilient catch 22 so that:
the end of the leg 30 catches within the horizontal slot :39 when the latch is in its latched position as shown in Fig-ure 4, this interengagement being released when the latch ~` is in its unlatched position as shown in Figure 7 so that the catch pin 38 will be enabled to slip downward out through the aperture 31 and disengage from the resilient catch 22.
The actuating wand 19 has a long handle 40 sur-mounted by a hinge 41, the two halves of which are fric-tionally engaged with one another by means of an adjust-able compression washer 42, the pressure exerted by the compression washer 42 being controlled by the adjusting screw 43. The upper section 44 of the hinge 41 is sur-mounted by a short extension 45 at the upper end of which is formed a circular cam 46 which is itself surmounted by a circular guide end post 47 which is projectable upward through the circular aperture 35 in the catch pin channel ~2t~03~
1 plate 25 when the actuating wand 19 is inserted upward through the aperture 48 in the cover shell 26 to actuate the latch mechanism.
Referring now specifically to Figures 4, 5 and 6, the latch mechanism is sho~m in its latched position so that the track 10 is securely latched to the ceiling by means of the latching plate 20 which is secured to the ceiling. As best seen in Figure 4, in the latched condi-tion, the head of the catch pin 3~ is projected through the circular aperture 49 in the latching plate 20 and the aperture 31 in the horizontal leg 30 of the resilient catch 22, and at the same time the projections 36 which extend from the end of the bottom wall 34 of channel plat~
25 are seated downward upon the shelf 33 formed on the 'vertical leg 32 of the resilient catch 22. In this way there is in effect a double latch.either of which is suf-ficient to maintain the l~tching engagement of the mechan-ism. The actuating wand 19 is shown with its working end inserted into the latch mechanism by projection upward through the circular aperture 48 in the cover shell 26 and aperture 35 in the channel plate 25, but before being actuated to unlatch the latching mechanism. If the actu-ating wand 19 were removed from Figure 4, the remainder of the figure would stay exactly as illustrated.
Consider now Figures 7 through 9 for an understand~
ing of the manner of unlatching the latch mechanism. Fig~
ure 7 illustrates the condition where the actuating wand L9 has been rotated 180 so that the circular cam 46 has later-ally pressed against the side edge of the shelf 33 on the vertical leg 32 of the resilient catch 22 and has caused the leg 32 to pivot outward through the open end 50 of the cover shell 26 by rotation around the pivot pin 21. This causes the projections 36 of the channel plate 25 to slip off of the upper surface of the shelf 33 and thereby be unlatched. Simultaneously, as the leg 32 of the resilient -126~3~(3 1 catch 22 pivots outward, the generally horizontal leg 30 of the resilient catch 22 slides to the left so that the end of the horizontal leg 30 moves sufficiently to dis-engage from the horizontal slot 39 in the catch pin 38.
~ith the catch pin 38 disengaged, it is able to move down-ward through the aperture 49 in the latching plate 20 so that the entire track section 10 and those portions of the latch mechanism secured thereto can swing downward away from the latching plate 20 into the phantom line position shown in Figure 1. A cubicle curtain can, for example, then be replaced, or some other article such as an I.V. carrier may be inserted or removed.
It should be noted that the actuating wand 19 is held captive within the ccver shell 26 and will remain that way unless the actuating wand is rotated an additional 180 to allow the circular cam 46 t~ register with the aperture 48 in the cover shell and thereby be removable.
The mechanism is relatched in the same way that it was unlatched. With the wand 19 in position as shown in Figure 7, the pivotable track section 10 is swung up-ward so that the upper edg~ of the projections 36 first engage with the bottom of the shelf 33 and drive the leg 32 outward into the position shown in Figure 7 while simultaneously moving the ~perture 31 into registry with the aperture 49 so that the catch pin 38 can easily project upward therethrough. Nith the track held in the position as shown in Figure 7 supported by the actuating wand 19J
the wand 19 is then rotated 180 so that it assumes the position in Figure 4, thereby relatching the mechanism by re-establishing the int~rlatched conditions shown in Figure 4. The actuating wand may then be removed and the mechanism is secure.
Having now described the invention in connection with a particularly illustrated embodiment thereof, it will be appreciated that modifications and variations of ~26~3~
1 the invention may now naturally occur from time to time to those persons normally skilled in the art without de-parting from the essentia scope or spirit of the inven-tion, and accordingly it is intended to claim the inven-tion broadly as well as specifically as indicated by theappended claims.
