Referring to FIGS. 1-6, reference numeral 10 generally designates a user interface housing for a patient support apparatus 14. The user interface housing 10 includes a body 18 having an upper portion 22 and a lower portion 26. First and second ribs 30, 34 extend from the upper portion 22 towards the lower portion 26 and the first and second ribs 30, 34 define first and second channels 38, 42, respectively. A locking body 46 is slidably disposed between the first and second ribs 30, 34. The locking body 46 includes a latch mechanism 50 configured to secure the locking body 46 in position.

Referring now to FIG. 1, the patient support apparatus 14 may include a hospital bed. While described as the patient support apparatus 14, it is within the scope of the disclosure that the patient support apparatus 14 may include a bed frame, a mattress, or any suitable structure for supporting a patient, including, but not limited to: other types of beds, surgical tables, examination tables, stretchers, recliners, and the like.

The patient support apparatus 14 may include a frame, which may be in the form of a base frame 54. An upper frame 58 may be coupled with the base frame 54. The upper frame 58 may be operable between raised, lowered, and tilted positions relative to the base frame 54. The patient support apparatus 14 may include a surface, such as a mattress 62 supported by one of the base frame 54 and the upper frame 58. The mattress 62 may be in the form of a cushion including a foam base and multiple layers.

The patient support apparatus 14 includes a head end 66 and a foot end 70. A headboard 74 is provided at the head end 66 and a footboard 78 is provided at the foot end 70. The patient support apparatus 14 may include a pair of head siderail assemblies 82 and a pair of foot siderail assemblies 86. In some examples, an interface 90, which may be a graphical user interface, may be coupled to an external side of at least one siderail of the head and foot siderail assemblies 82, 86.

As illustrated in FIG. 1, a support arm 94 is coupled with the head end 66 of the patient support apparatus 14. Alternatively, the support arm 94 may be coupled with of at least one siderail of the head and foot siderail assemblies 82, 86, or with one of the base frame 54 and the upper frame 58, but is not limited to such examples. The support arm 94 generally includes a fixed portion 98 and a pivotable portion 102. The pivotable portion 102 extends laterally from the fixed portion 98 and is configured to rotate relative to the fixed portion 98.

A strand, or cord 106, may depend from the pivotable portion 102 and may be repositioned to a variety of locations about the patient support apparatus 14. The user interface housing 10 may be coupled with the cord 106. The pivotable portion 102 and/or the cord 106 generally has exceptional flexibility to provide support for accessing the user interface housing 10 at different angles and positions relative to the patient support apparatus 14. However, the user interface housing 10 may be integrated with any suitable component of the patient support apparatus 14.

A user interface 108 is secured to the user interface housing 10, which may be used by a caregiver or a patient. The user interface 108 may be in the form of a touch screen tablet computer, a smartphone, and the like, which may be generally rectangular in shape. However, it is also contemplated that the user interface 108 may be of various shapes, which can be secured to the user interface housing 10.

Referring now to FIG. 2, the user interface housing 10 is illustrated without the user interface 108. The body 18 of the illustrated user interface housing 10 includes at least one gripping surface 110, which may include one or more handles 110. As illustrated, the user interface housing 10 includes two handles 110 that each extend from the upper portion 22 to the lower portion 26 of the body 18. The handles 110 may be covered in a material, such as a soft, silicone to provide an enhanced gripping surface and which is easily cleanable.

In some examples, as illustrated in FIG. 2, the handles 110 extend outwardly from the body 18 to define apertures 114. The apertures 114 are generally oval, elliptical, or lanceolate shaped and may be dimensioned such that a hand of a user can reach at least partially through one of the apertures 114, which may be beneficial for grasping the body 18 or one of the handles 110. The first and second ribs 30, 34 defining the first and second channels 38, 42 are disposed on a middle portion 118 of the body 18, which may be located between the apertures 114. However, it is within the scope of this disclosure for the user interface housing 10 to include alternative gripping arrangements, which may or may not include the apertures 114. For example, one or more handlebars, cup handles, pull handles, or knobs, etc. may extend from the body 18 to facilitate moving and gripping of the user interface housing 10.

Still referring to FIG. 2, a latch actuator 122 is operably coupled with the latch mechanism 50 for selectively releasing the locking body 46, which enables the locking body 46 to be slidable within the first and second channels 38, 42. At least a portion of the latch mechanism 50 may be disposed within an interior of an upper end 124 of the locking body 46. The upper end 124 may be in the form of a curved body that extends outwardly from a planar portion 126 of the locking body 46. Alternatively, the upper end 124 may be any suitable shape, which may be rectangular or flat and may include a non-slip cleanable surface.

In various examples, the latch actuator 122 includes a button 128, which may be generally flush with the upper end 124. Thus, the button 128 generally includes a shape complementary to the shape of the upper end 124. In addition to the button 128 being flush with the upper end 124, molding the button 128 in the same color as the locking body 46 may provide the aesthetically pleasing appearance of a seamless interface between the button 128 and the locking body 46. Moreover, the button 128 generally has a continuously arcuate outer surface, which contributes to the seamless interface between the button 128 and the locking body 46. While illustrated as the button 128, the latch actuator 122 may include any suitable component for actuating the latch mechanism 50, which may include, but not limited to: a tab, a handle, a push-button, a toggle, etc.

As shown in FIG. 2, a shelf 130 is coupled with the lower portion 26 of the body 18, which is dimensioned to receive an edge, which may be a lower edge, of the user interface 108 (FIG. 1). The shelf 130 includes a first shelf portion 134 and a second shelf portion 138, which extend upwards to retain the edge of the user interface 108. However, the shelf 130 may be in any suitable configuration that provides a surface for the user interface 108, which may include a single, continuous portion and may or may not extend upwardly.

Additionally, the locking body 46 includes a flange 142, which extends downwardly from the latch actuator 122 thereby defining a recess 146 (FIG. 4). The recess 146 is dimensioned to receive another edge of the user interface 108, which may be an upper edge. The height, or position, of the flange 142 and the recess 146 is adjusted by repositioning the locking body 46. Thus, the user interface 108 may be secured to the user interface housing 10 in a clamping manner by way of the shelf 130 and the flange 142. In this way, the user interface housing 10 may accommodate a user interface 108 of a variety of sizes.

FIG. 3 is a cross-sectional view of the latch mechanism 50 along line III-III of FIG. 2, more clearly illustrating the first and second channels 38, 42. The latch mechanism 50 includes a flexible body 150 coupled to a rear side 154 of the locking body 46. The flexible body 150 may be made of any suitable material configured to be deformed elastically. The flexible body 150 may be fastened to the rear side 154 via first and second molded bosses 158, 159. In this example, the flexible body 150 includes first and second loops 162, 163 configured to stretch over the first and second bosses 158, 159, respectively, to form a taut connection. However, it is within the scope of this disclosure for the flexible body 150 to be coupled to the locking body 46 via any suitable fastening technique including adhesives, co-molding, fasteners, and the like.

The flexible body 150 generally includes a first body portion 166 laterally spaced from a second body portion 170, which is coupled to one another with a connecting portion 174. The connecting portion 174 includes first and second arcs 176, 177 coupled with the first and second body portions 166, 170. The first and second arcs 176, 177 may be coupled via a bight portion 179, which may be generally concave up while the first and second arcs 176, 177 may be generally concave down. Furthermore, the bight portion 179 may include a larger perimeter than each of the first and second arcs 176, 177. The arcuate construction of these features allows for increased flexibility resulting in a robust system that can be locked and unlocked over many cycles. In various examples, the connecting portion 174 may be generally U-shaped. However, the connecting portion 174 may be generally horizontal, V-shaped, etc.

Still referring to FIG. 3, the first and second body portions 166, 170 extend substantially along the height of the rear side 154 of the locking body 46. Furthermore, the first and second body portions 166, 170 include first and second projections 178, 182, respectively. The first and second projections 178, 182 extend from the first and second body portions 166, 170 towards first and second apertures 186, 190 on the locking body 46, respectively. Accordingly, the first and second projections are laterally spaced from one another on opposing sides of the locking body 46 and generally extend outward, away from one another. The first and second apertures 186, 190 may be positioned on the side of the locking body 46 adjacent the channels 38, 42, respectively. The first and second channels 38, 42 each include a ratcheting mechanism, which may include a plurality of vertically spaced teeth 194. Each tooth 194 defines a tooth surface, which may be in the form of a sloped surface. The first and second projections 178, 182 terminate in angled edges 198, 202, respectively, which are generally complementary to the surface of each tooth 194, thereby forming a pawl.

In a locked or extended position, as illustrated in FIG. 3, the first and second projections 178, 182 extend outwardly from the first and second apertures 186, 190, and engage at least one tooth surface. Thus, the first and second projections 178, 182 may catch against a steeply sloped edge of the engaged teeth 194 and prevent any further motion in an upward direction. However, the locking body 46 may be pushed downwardly in the locked position to secure the user interface 108 between the shelf 130 and the recess 146. In this way, the locking body 46 may be pushed downwards until the upper edge of the user interface 108 contacts the locking body 46 within the recess 146 and prevents further downward movement.

The flexible body 150 further includes a first flexible tab 206 and a second flexible tab 210 coupled with the first and second projections 178, 182, respectively. The first and second flexible tabs 206, 210 are angled inwardly such that first and second flexible tabs 206, 210 extend towards each other. Furthermore, the latch actuator 122 may be operably coupled with a first shaft 214 and a second shaft 218 disposed adjacent to the first and second flexible tabs 206, 210 respectively. The first and second shafts 214, 218 are generally disposed outward from the first and second flexible tabs 206, 210 with the first and second flexible tabs 206, 210 extending at least partially between the first and second shafts 214, 218. In the locked, or extended position, the first and second shafts 214, 218 may be adjacent, or in contact with, the first and second flexible tabs 206, 210.

The latch actuator 122 may include a first rib 216 and a second rib 220 disposed within an aperture 222 defined by the locking body 46. The ribs 216, 220 may be sized to extend substantially the height of the aperture 222 to limit or prevent up/down movement of the button 128. The first and second ribs 216, 220 are laterally spaced from one another and are generally positioned at opposing side edges of the aperture 222. Accordingly, the first and second shafts 214, 218 are each disposed between the first and second ribs 216, 220. The first and second ribs 216, 220 at least partially prevent movement of the first and second shafts 214, 218.

In examples where the ribs 216, 220 are not included on the latch actuator 122, to transition from the locked position to a released, or retracted position, the latch actuator 122 may be shifted upwardly, which may in turn shift the first and second shafts 214, 218 downward. Thus, the first and second shafts 214, 218 may contact and push down on the first and second flexible tabs 206, 210, such that the first and second flexible tabs 206, 210 are pressed more closely towards each other against a biasing force of the flexible body 150. In this way, a space between the first and second flexible tabs 206, 210 is decreased. Due to the elastic properties of the flexible body 150, the first and second projections 178, 182 can be pulled inwards upon movement of the first and second flexible tabs 206, 210 inwards. Thus, upon sufficient movement inwards, the first and second projections 178, 182 do not engage the tooth 194 and the locking body 46 may slide unrestricted between the upper portion 22 and the lower portion 26 of the body 18.

Referring now to FIG. 4, the locking body 46 and the stationary button 128 are more clearly illustrated. In some examples, the button 128 may include a column 226 defining a channel 230 positioned on a rear side 234 thereof. The channel 230 is sized to receive a shaft 238 coupled with the latch mechanism 50 in order to couple the button 128 to the latch mechanism 50. The shaft 238 includes a keyed portion 240 complementary to the shape of the channel 230 to facilitate proper insertion of the button 128. However, the button 128 may be coupled with the latch mechanism 50 in any suitable configuration, which may include fasteners, clasps, snaps, magnets, etc. in order to form a non-permanent or permanent joint.

At least a portion of the latch mechanism 50 may be pivotable within the aperture 222 on the locking body 46. A spring 244 (FIG. 5A) facilitates pivoting of at least a portion of the latch mechanism 50. The ribs 216, 220 provided on the rear side 234 of the button 128 generally prevent the button 128 from sliding movement, thereby preventing pivoting of at least a portion of the latch mechanism 50. For example, as the ribs 216, 220 extend through the aperture 222 on the locking body 46, the ribs 216, 220 may prevent up/down movement of the button 128. Therefore, the button 128 may restrict pivoting of the latch mechanism 50 and, consequently, restricting or limiting movement of the locking body 46. The use of the button 128 may be beneficial in applications where locking/releasing the user interface 108 requires additional safeguarding.

FIGS. 5A and 5B illustrate an alternative technique for transitioning the locking body 46 from the locked position to the released position, which may be beneficial when the button 128 is coupled with the latch mechanism 50. The locking body 46 may define a recess, or an access notch 250 located on the rear side 154 at the upper end 124. The access notch 250 is configured to receive or allow a tool 254, such as a screwdriver, to access the rear side 154 of the locking body 46 when mounted to the user interface housing 10. The tool 254 may be any suitable tool configured to access the rear side 154, which may include a tool having a sufficient length and width to fit through the access notch 250 and reach the connecting portion 174. FIG. 5A illustrates the flexible body 150 in the extended position where the first and second projections 178, 182 extend outwardly from the first and second apertures 186, 190.

FIG. 5B illustrates the flexible body 150 in the retracted position. Application of a predetermined force, FD, by the tool 254 adjusts the latch mechanism 50 from the extended position to the retracted position. Application of the predetermined force, FD on the connecting portion 174 forces the connecting portion 174 downward, away from the first and second apertures 186, 190. As a result, the first projection 178 is rotated inwardly about the first boss 158 towards the connecting portion 174 such that the first projection 178 is withdrawn and no longer disposed within the first aperture 186. Likewise, application of the predetermined force, FD, by the tool 254 on the connecting portion 174 rotates the second projection 182 inwardly about the second boss 159 towards the connecting portion 174, such that the second projection 182 is withdrawn and no longer disposed within the second aperture 190. The force, FD, may be applied to the bight portion 179 of the connecting portion 174, which causes deformation of the bight portion 179 and the first and second arcs 176, 177. In this way, the bight portion 179 and the first and second arcs 176, 177 flex in order to draw in the first and second projections 178, 182.

Referring now to FIG. 6, the user interface housing 10 is illustrated with an additional or alternative configuration of a shelf 330. Similarly to the shelf 130, the shelf 330 includes a first shelf portion 334 and a second shelf portion 338, which extend upwards to retain the edge, which may be a lower portion, of the user interface 108. However, the shelf portions 334, 338 may have a greater length to generate a wider shelf area. In some examples, the shelf 130 or shelf 330 includes a material 342, such as a soft silicone, to provide a grip surface for an edge of the user interface 108.

The shelf 330 may further include stoppers, which are illustrated in the form of vertically extending edge pieces 346. The edge pieces 346 are sized and positioned within the shelf 330 to prevent the user interface 108 from sliding out of the user interface housing 10 horizontally. The position of the edge pieces 346 may be adjusted to accommodate various widths of user interfaces 108. Accordingly, the edge pieces 346 are adjustable along a horizontal plane to define different widths for retaining different user interfaces 108. In some examples, the edge pieces 346 may be dropped in and pivoted into a locked position on the shelf 330. Furthermore, the shelf 330 may include a plurality of indentations sized to receive the edge pieces 346 to lock the edge pieces 346 into position on the shelf 330. Alternatively, the edge pieces 346 may be slidably coupled with the shelf and locked into position with a fastener. Even further, the edge pieces 346 may be fixed and secured into position on the ends of the shelf 330. For example, the edge pieces 346 may be molded as an integral piece with the shelf 330.

One or both of the first shelf portion 334 and the second shelf portion 338, including the edge pieces 346, may be adjustable along a horizontal plane to define different widths to accommodate electronic devices of varying dimensions. For example, the body 18 of the user interface housing 10 may include a groove, a track, a slide, or a similar feature that engages the first shelf portion 334 and the second shelf portion 338. The first and second shelf portions 334, 338 define a first width when in a first position and a different second width when in a second position to accommodate user interfaces 108 having differing widths. The first and second shelf portions 334, 338 and/or the edge pieces 346 may be adjusted to minimize horizontal movement of the user interface 108 on the shelf 330, and thereby prevent removal of the user interface 108 from the user interface housing 10.

Use of the present device may provide for a variety of advantages. For example, the first and second projections 178, 182 each engage a sloped surface of the teeth 194. The sloped surface provides for downward movement of the locking body 46 while preventing upward movement. Additionally, the button 128 includes the first and second ribs 216, 220 that extend into the aperture 222 defined by the locking body 46. The first and second ribs 216, 220 prevent sliding movement of the button 128, and consequently, at least partially prevent pivoting of the latch mechanism 50. Limiting the pivoting of the latch mechanism 50 prevents the locking body 46 from moving toward the upper portion 22 of the body 18 of the user interface housing 10 while allowing movement toward the lower portion 26. This one directional movement secures the user interface 108 in the user interface housing 10 while preventing unwanted removal of the user interface 108 from the user interface housing 10. Further, the button 128 has a continuous arcuate surface that defines a shape complementary to the shape of the upper end 124 of the latch mechanism 50. The continuous arcuate surface reduces the ability of a user to grasp and move the button 128, providing further security for retaining the user interface 108. Moreover, the upper end 124 of the locking body 46 may define the access notch 250 for receiving the tool 254. In such examples, the locking body 46 may be adjusted toward the upper portion 22 of the body 18 in response to force being applied to the flexible body 150 by the tool 254. Moreover, the user interface housing 10 provides security for the user interface 108. These and other advantages may be realized and/or achieved.
