Additional features, which alone or in combination with any other feature(s), such as those listed above, may comprise patentable subject matter and will become apparent to those skilled in the art upon consideration of the following detailed description of various embodiments exemplifying the best mode of carrying out the embodiments as presently perceived.
The detailed description particularly refers to the accompanying figures, in which:
A chair bed 10 of the present disclosure includes a head end 12, a foot end 14, and sides 16, 18. The chair bed 10 is able to move between a conventional bed position, as shown in
Looking now to
Illustratively, the bed 10 also includes a mattress assembly 40 configured to rest upon a mattress support surface of the articulating deck 24 of the bed 10. Thus, in the conventional bed position, shown in
As discussed above, the chair bed 10 includes the footboard 20, shown in detail in
Looking now to
The posts 60 of the footboard 20 are coupled to and extend away from the main panel 64 of the bracket 62. In particular, the longitudinal axis of each post 60 is generally perpendicular to a plane defined by the main panel 64 of the bracket 62, as shown in
The footboard 20 also includes a latch mechanism 80, shown best in
Looking now to
The latch mechanism 80 further includes a latch 88 positioned within the latch-receiving space of each support 82 and pivotably coupled to the spaced-apart flanges 86 of each support 82. As such, the latch mechanism 80 includes two latches 88 which are each configured to couple with a coordinating structure (not shown) of the foot section 32 of the deck 24 of the bed 10 in order to couple and lock the footboard 20 to the deck 24 of the bed 10. Illustratively, each latch 88 includes a head portion 90 configured to engage with the coordinating structure of the foot section 32 of the deck 24, a body portion 92 coupled to the head portion 90, and a foot portion 94 coupled to and extending downwardly from the body portion 92. The body portion 92 of each latch 88 is pivotably coupled to the pair of spaced-apart flanges 86 of the respective support 82 to which each latch 88 is coupled. Illustratively, a bar 96 of the latch mechanism 80 is coupled to and extends between the foot portion 94 of each latch 88. As is discussed in greater detail below, the bar 96 operates to coordinate the movement of the latches 88 with each other such that the latches 88 move generally simultaneously with each other. As such, movement of one latch 88 causes the other latch 88 to move therewith.
As shown in

Looking still to
In use, the footboard 20 is coupled to the deck 24 of the bed 10 when the bed 10 is positioned in any of a number of conventional bed positions, such as the supine position shown in
When the posts 60 are positioned within the respective post-receiving receptacles 150, the latch mechanism 80 is normally engaged with the coordinating structure (not shown) of the foot section 32 of the deck 24 such that the footboard 20 is in a locked position with respect to the deck 24. In particular, when the latch mechanism 80 is in the locked position, the head portion 90 of each latch 88 are engaged with the coordinating structure of the foot section 32 of the deck 24. For example, the head portion 90 of each latch 88 may be received within a slot or aperture of the foot section 32 of the deck 24 such that a rearward surface 89 of each latch 88 (as shown in
In order to remove the footboard 20 from the foot section 32 of the deck 24, the caregiver must move the latch mechanism 80 from the normally locked position to the unlocked position. As noted above, this may be accomplished through the use of two different tool-receivable receptacles 100, 120 configured to receive a particular tool therein. Illustratively, the first tool-receivable device is the card-receiving receptacle 100. To use the card-receivable receptacle 100, the caregiver simply slides a card, such as their caregiver ID badge, a credit card, or other similarly-sized card through the card-receiving slot 110 of the receptacle 100. In use, the caregiver's card engages and moves a lever (not shown) coupled to and/or located within the main body 50 of the footboard 20. Illustratively, this lever is coupled to one of the two latches 88 of the latch mechanism 80 and forms part of the latch mechanism 80. As such, movement of the lever per the caregiver's card operates to move one of the two latches 88 from the normally upright, locked position to the unlocked position. In other words, movement of the lever operates to pivot one of the two latches 88 rearwardly about the pivot pin 98.
As noted above, the latch mechanism 80 includes the bar 96 coupling the foot portion 94 of each latch 88 together. Thus, movement of one of the latches 88 to the unlocked position operates to simultaneously move the other latch 88 to the unlocked position as well. Illustratively, while the caregiver's card is described as engaging a lever of the latch mechanism 80, it should be understood that the latch mechanism may include any other suitable structure which may be engaged by the caregiver's card in order move one of the latches 88 to the unlocked position. Such structure may be directly coupled to one of the latches 88 or may be indirectly coupled to one of the latches 88 via a number of other movable structures, such as linkages, for example. It should also be understood that the caregiver's card may directly engage a portion of one of the latches 88 in order to move the latch 88 to the unlocked position.
Once both latches 88 are moved to the unlocked position, the caregiver is able to pull on the footboard 20 to slide the posts 60 of the footboard 20 out of the post-receiving receptacles 150 of the foot section 32 of the deck 24 in order to remove the footboard 20 from the deck 24 of the bed 10. As noted above, the footboard 20 is removed from the deck 24 by sliding the footboard 20 in a direction 65 away from the deck 24 and parallel to a plane defined by the foot section 32 of the deck 24. Once the footboard 20 is fully removed from the deck 24, the bed 10 may be moved to the chair egress position shown in
As noted above, the footboard 20 includes yet another tool-receivable device. In particular, the footboard 20 includes the pen-receiving receptacle 120. In order to remove the footboard 20 from the deck section 24 of the bed 10, a user may insert a pen or another similarly sized and shaped long, cylindrical device into the aperture 124 of the receptacle 120. Similar to that described above in regard to use of the card-receiving receptacle 100, the caregiver's pen operates to engage and move the lever coupled to and/or located within the main body 50 of the footboard 20. As noted above, this lever is coupled to one of the two latches 88 of the latch mechanism 80 such that movement of the lever per the caregiver's pen operates to move one of the two latches 88 from the normally upright, locked position to the unlocked position. Movement of one of the latches 88 operates to simultaneously move the other latch 88 as well such that both latches 88 are moved to the unlocked position.
Illustratively, while the caregiver's pen is described as engaging a lever of the latch mechanism 80, it should be understood that the latch mechanism 80 may include any other suitable structure which may be engaged by the caregiver's pen in order move one of the latches 88 to the unlocked position. Such structure may be directly coupled to one of the latches 88 or may be coupled to one of the latches 88 via a number of other movable structures, such as linkages, for example. It should also be understood that the caregiver's pen may directly engage a portion of one of the latches 88 in order to move the latch 88 to the unlocked position. Further, the latch mechanism 80 may be configured such that the caregiver's pen engages the same structure that the caregiver's card engages when the card is slid through the card-receiving receptacle 100. Alternatively, the latch mechanism 80 may be configured such that the caregiver's pen engages a structure different from that which is engaged by the caregiver's card. Regardless, both the caregiver's card and the caregiver's pen operate as tools used to engage a lever or other such structure capable of moving one of the latches 88 to the unlocked position.
Illustratively, while the caregiver's card and the caregiver's pen are discussed above as tools receivable within, or engagable with, the two tool-receivable receptacles 100, 120 of the footboard 20, it should be understood that other tools may be used with each of the tool-receivable receptacles 100, 120 as well. In particular, any device, or tool, which has at least a portion that is thin enough to be received within the card-receiving slot of the receptacle 100 may be used with the receptacle 100 in order to move the latches 88 of the latch mechanism 80 to the unlocked position. Similarly, any device, or tool, which includes at least a portion that is able to fit within the aperture 124 of the receptacles 120 may be used with the receptacle 120 in order to move the latches 88 of the latch mechanism 80 to the unlocked position. Furthermore, it should be understood that while the footboard 20 includes the particular tool-receivable receptacles 100, 120 described above, the footboard 20 may include different or other tool-receivable devices as well which similarly operate to allow a user to use a tool to move the latches 88 of the latch mechanism 80 to the unlocked position.
For example, in another embodiment, the footboard 20 may be configured to include a coin-receiving slot (not shown) configured to receive a coin, such as a quarter, dime, nickel, penny, or other similarly-sized object at least partially therein. In use, the coin, once inserted into the slot, may be turned approximately 90 degrees in order to rotate a latch or lever 90 degrees therewith. Rotating the latch or lever would similarly operate to either directly or indirectly engage at least one of the latches 88 of the latch mechanism 80 in order to move the latches 88 to the unlocked position.
In still another embodiment, a graphical user interface 160 (shown in
Illustratively, in all embodiments shown and/or described above, the footboard 20 is a tool-removable footboard in that a tool is required in order to allow a caregiver to remove the footboard 20 from the deck 24 of the bed 10. Without the use of this tool, the footboard 20 remains in a locked position on the deck 24 of the bed 10 and cannot be removed by the caregiver. Illustratively, the tool may be a card, a pen, a coin, or other similarly sized and shaped structures. Furthermore, the tool may also be a user interface, such as the \user interfaces 160, 162 described above. It should be understood that while various tools are described for use with the footboard 20, the footboard 20 may be configured to include other suitable tool-receiving devices for use with other suitable tools. In particular, the footboard 20 of the present disclosure may include a tool-receiving device having an aperture formed therein that is specifically sized and configured for a particular tool to be received therethrough in order to engage a portion of the latch mechanism 80 to move at least one of the latches 88 from the locked position to the unlocked position. Furthermore, other electronic devices may be coupled to the latch mechanism 80 to allow a user to provide instructions and send a signal through a control system to move the latch mechanism 80 to the unlocked position.
Further illustratively, while the particular latch mechanism 80 is shown and described above, it is within the scope of this disclosure for the footboard 20 to include any other suitable latch mechanism configured to engage a portion of the bed 10 in a locked position and to disengage a portion of the bed in an unlocked position. Such other latch mechanisms may include one or more latches, levers, or other such structures which are received within or engaged with a coordinating structure of the bed 10 when the latch mechanism is in the locked position in order to prevent a caregiver from removing the footboard 20 from the deck 24 of the bed 10. Such other latch mechanisms may also include any suitable latch which is movable (linearly and/or pivotably) to selectively engage and disengage the coordinating structure of the deck 24 of the bed.
Finally, as noted above, any such suitable latch mechanism of the footboard 20 may include a movable structure adjacent the tool-receiving device of the footboard 20 and generally accessible through an aperture or slot of the tool-receiving device of the footboard 20 in order to allow a tool to move the latch mechanism to an unlocked position. In other words, the tool-receivable device provides access (such as through an opening) to the latch mechanism to allow the coordinating tool to engage the latch mechanism and move the latch mechanism to the unlocked position. Alternatively, the latch mechanism may be in electrical communication with a tool-receiving device, such as a solenoid, for example, which receives an electrical signal providing instructions to move the latch mechanism. In particular, each of the illustrative user interfaces 160, 162 described above may be considered as a tool while the solenoid, or other such device which acts upon the latch mechanism, may be considered as the tool-receiving device in that the solenoid receives a signal, i.e., the unlock signal, from one of the user interfaces 160, 162.
Although certain illustrative embodiments have been described in detail above, variations and modifications exist within the scope and spirit of this disclosure as described and as defined in the following claims. Further, while the invention has been illustrated and described in detail in the foregoing drawings and description, the same is to be considered as illustrative and not restrictive in character, it being understood that only illustrative embodiments thereof have been shown and described and that all changes and modifications that come within the spirit of the invention are desired to be protected.
