1. Field of the Invention
The presently disclosed invention relates to adjustable tables and, more particularly, tables that are ergonomically suitable for use in connection with beds, wheelchairs, patients' chairs and recliners such as used in hospitals and other health care institutions.
2. Discussion of the Prior Art
Adjustable tables have been used for many years for a variety of reasons and purposes. In the case where users are bedridden or have limited mobility such as patients in hospitals or nursing care facilities, such tables help provide meals and are otherwise useful in affording a platform for personal care. Such tables are also helpful in connection with the patient's pursuit of other activities such as reading or other enjoyments and interests.
Persons who are bedridden or have limited mobility have a limited range of motion and body positions available to them. If has been found that such limitations on range of motion or position can cause patient discomfort and, in some cases, can even be harmful to the patient. Accordingly, in health care setting and elsewhere, there has been increasing emphasis on beds and other furniture that is ergonomically suited to the user's needs
With regard to overbed tables, there have been significant improvements to their ergonomic character. For example, U.S. Pat. No. 8,316,777 describes an overbed table with improved stability. In that case, the table was provided with arm supports suitable for use by patients whose injuries or disabilities required adjustable arm supports by which they could gain leverage to move themselves or to support others who may be assisting them. To improve the stability of the overbed, the position of the arm rests relative to the supporting platform for the table was redesigned. The redesign allowed significantly greater leverage to be brought against the arm rests without the risk that the table would pitch forward and result in frustration or even injury to the patient.
More recently, it has been recognized that overbed tables would be still further improved if they could better accommodate certain user activities. For example, when patients that participate in activities that involve very limited or highly repetitive movements or body positions such as reading, it would be preferable that the overbed table can accommodate the position that is most ergonomically favorable to them. It has been found that, in many cases, this involves an overbed table with capabilities for a foldable top surface. Particularly advantageous would be an overbed table that afforded a top surface that had a range of foldable positions as this would accommodate not only a number of activities, but also a variety of body types and sizes among those people who are engaging in such activities.
In addition to the forgoing, it also has been found that improved designs in overbed tables should also better accommodate the need for cleaning. It would be particularly beneficial if the design would enable easier, faster cleaning procedures. That would not only result in considerable costs savings, but would also tend to avoid resistance and objections to regular cleaning so as to result in cleaner, safer overbed tables.
In accordance with the presently disclosed invention, an overbed table includes a desktop body that is supported by at least one elongate member that is secured to a support platform. A flexible table top that is secured to the top of the desktop body includes a table top frame and a flex top. The table top frame is pivotally connected to the back of the desktop body so that the overbed table can be opened from the top for access to the desktop body by lifting the table top frame. In some cases, friction hinges are used to connect the table top frame to the desktop body so that the top will not close inadvertently.
A flex top that is connected to the table top frame includes two panels that are connected by an integrated hinge. The flex top includes pins that cooperate with stops that are configured along a track that is defined in the table top frame to control the position of the two flex top panels. In one position, the panels are in the same plane. When the pins of the flex top are moved to other stop positions in the track, the back of the flex top moves forward causing the two panels to form a peak along the axis of the integrated hinge that joins the panels. The rise in the peak is determined by the position of the pins in the track; the further forward the pins are moved, the steeper the peak that is formed by the two panels.
Preferably, the front of the flex top is connected to the front of the table top frame by a biased fastener that allows the front of the flex top to be manually uncoupled from the front of the table top frame. This allows the flex top to be pivoted away from the table top frame so that the bottom surface of the flex top can be cleaned quickly and easily.
Also preferably, the overbed table includes armrests that are connected to the desktop body by a slide assembly. The slide assembly includes a slide housing and a rail that cooperates with the slide housing and that is secured to the bottom of the armrest. The user can adjust to the position of the armrest relative to the position of the desktop body by pushing or pulling on the armrest to achieve the desired location. The slide housing is secured to the desktop body. Accordingly, the angular pitch of the armrest relative to the desktop body is determined by the orientation of the slide housing with respect to the desktop body.
In some cases, a gasket may be attached to the desktop body at a location between the desktop body and the bottom of the armrest. The gasket acts to seal fluids from traveling underneath the armrest to locations that are difficult to access for purposes of cleaning the overbed table.
It is sometimes preferable that the flex top includes third and fourth panels that are connected to the first and second panels by respective second and third integrated hinges. In that case, the third panel includes the biased fastener for coupling and uncoupling the front of the flex top to the front of the tale top frame and pins that cooperate with stops in the track extend from the fourth panel. In all cases, the integrated hinges provide a smooth, continuous surface on the top of the flex top so that there are no cracks or valleys between adjacent panels.
In some embodiments, the flex top includes border segments with a top surface that is at elevation that is higher than the top surface of the non-border portions of the flex top. The border segments in combination with the continuous top surface of the flex top across the integrated hinges allows liquids that may be spilled on the top surface of the flex top to be contained on the flex top thus avoiding liquids flowing from the overbed table unto bedding or elsewhere. Preferably, the top surface of the flex top is inclined downwardly in the direction of the user. One advantage of this is that spilled liquids will be pooled on the top surface of the flex top for easier and faster cleanup.
These and other objects, details and advantages of the presently disclosed overbed table will become better understood or apparent from the following descriptions and examples that are further disclosed herein.
A presently preferred embodiment of the disclosed invention is shown and described in connection with the accompanying drawings wherein:

Referring to
Armrests 103 are secured to respective rails 108 of corresponding slide assemblies 104. Armrests 103 are moveable together with rail 108 so that the position of armrests is easily adjusted by the user.
In some embodiments, the disclosed overbed table includes a desktop body 30 wherein the shell 100 includes a gasket that is located on shell 100 of desktop body 30. Gasket 110 is positioned between shell 100 of desktop body 30 and armrest 103 to seal against fluid flow between desktop body 30 and the underside of armrest 103. Gasket 110 thus seals against the flow of fluids that may be spilled on or around shell 100 and flow to parts of the overbed table that would be more difficult and expensive to clean.
In the presently preferred embodiment, fasteners 118, 120 are normally biased to extend through openings 114, 116 at times when the fasteners are respectively aligned with the openings. Fasteners 118, 120 may be of the type that they can be manually displaced from openings 114, 116. Is some embodiments, fasteners 118, 120 may be spring plungers.
In the presently preferred embodiment,
At times when fasteners 118, 120 are in their normally biased state, the fasteners extend from first and second edges 128, 130 respectively. To remove fasteners 118, 120 from openings 114, 116 respectively, the user manually presses inwardly against the ends of fasteners 118, 120 in the longitudinal direction to overcome the bias force of fasteners 118, 120 and push the respective ends of the fasteners out of openings 114, 116. Flex top 40 is then pivotally connected to fable top frame 38 by pins 74, 76 such that flex top 40 be pivoted upwardly from the front edge 42 to afford access to the bottom of flex top 40 so that it can be quickly and easily cleaned.
Also shown in
In the operation of flex top 40, starting with fasteners 118, 120 engaged in openings 114, 116 and pins 74, 76 engaged with the first stops 78, 80 respectively, the flex top 40 has a planar geometry that is essentially parallel to the plane of table top frame 38. To form the folded top feature of the disclosed overbed table as shown in
As shown in the drawings, second integral hinge 124 defines a groove 150 between bottom surface 60 of first panel 54 and bottom surface 142 of third panel 122. Similarly, third integral hinge 134 defines a groove 152 between bottom surface 64 of second panel 56 and bottom surface 146 of fourth panel 132.
As particularly shown in
As also shown in the drawings, first panel 54 defines a first edge 154 and a second edge 156 that is oppositely disposed on first panel 54 from first edge 154. The top surface 58 of panel 54 of flex top 40 defines a first border segment 158 and a second border segment 160. Border segments 158 and 160 are adjacent first and second edges 154, 156 respectively of first panel 54. The top surface of first and second border segments 158, 160 of first panel 54 are elevated from the top surface 58 of the portion of first panel 54 that is between first and second border segments 158, 160. Also, top surface 58 of the portion of first panel 54 that is between first and second border segments 158, 160 is inclined with respect to the top surface of border segments 158, 160. The sense of the incline across the top surface is downwardly in the direction from first integral hinge 68 toward the concave side 126 of flex top 40.
Similarly to the top surface of first panel 54, second panel 56 defines a first edge 162 and a second edge 164 that is oppositely disposed on second panel 56 from first edge 162. The top surface of second panel 56 of flex top 40 defines a first border segment 166 and a second border segment 168. First and second border segments 166, 168 are adjacent first and second edges 162, 164 of second panel 56. The top surface of first and second border segments 166, 168 of second panel 56 are elevated above the top surface 62 of the portion of second panel 56 that is between first and second border segments 166, 168. The top surface of the portion of second panel 56 between first and second border segments 166, 168 is also inclined with respect to the top surface of first and second border segments 166, 168. The sense of the incline across the top surface is downwardly in the direction from side 136 of flex top 40 toward first integral hinge 68.
The structure of first and second border segments 158 and 160 in combination with first and second border segments 166, 168 together with inclined portions of the top surfaces 58 and 62 between those border segments causes fluids that may be spilled on top surfaces 58, 62 of panels 54, 56 to pool on the top surface of flex top 40 near the concave side 126 of third panel 122. Thus, here again the disclosed overbed table provides for quick and easy cleanup of spilled liquids.
To save on material costs to reduce the weight of first panel 54 and second panel 56, the bottom surface 60 of first panel 54 defines a recessed area 170 between first and second edges 154, 156 of the first panel. Similarly, the bottom surface 62 of second panel 56 defines a recessed area 172 between first and second edges 162, 164 of second panel 56. This reduction in weight helps to make operation of the flex top easier.
