DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS OF THE INVENTION

[0024] Referring now to the various figures of the drawing wherein like reference characters refer to like parts, there is shown in FIG. 1 an exemplary device 20 configured for mounting (e.g., releasably securable mounting) on an over-bed type table, e.g., table 10. The over-bed table can be of various constructions and basically comprises a frame 12 having a base 12A, on which plural rollers or casters 14 are mounted. The frame includes an adjustable-height post 12B on which a table top 16 is mounted. The table top 16 if typically of rectangular shape and is of sufficient length to completely overlie the width of a bed upon which a patient will be located.

[0025] The device 20 basically comprises a housing or case 22 and a stack 24 (FIG. 2) of plural sanitary mats or sheets. The case includes a generally planar rectangular bottom wall 26, an upstanding side wall 28, plural clips 30, a top wall 32, an open window 34 in the top wall and a hollow interior or chamber 36 bounded by the walls of the housing and underlying and in communication with the open window. The side wall is made up of four linear sections, each of which extends along a respective side/end of the bottom wall and the top wall. The top wall 32 is in the form of a very narrow lip 38, whereupon virtually the entire top portion of the case 22 constitutes the open window 34. In accordance with one preferred aspect of this invention the case is formed as an integral unit, e.g., molded of a plastic material. However, that is merely exemplary of various constructions for the case.

[0026] As best seen in FIG. 2, the stack 24 is made up of a plurality of sanitary mats 24A. Each mat is a thin sheet of any suitable material, e.g., a non-porous plastic. Preferably the stack includes twenty to thirty mats or sheets, which are rectangular and of the same size and shape so that the stack 24 just fits within the hollow interior or chamber 36 of the case, with only minimal portion of the periphery of the stack underlying the narrow lip 38. The mats or sheets 24A of the stack preferably have a sticky or tacky coating or adhesive on their undersurface so that they are releasably secured to each other, e.g., the uppermost sheet or mat can be readily peeled off of the underlying sheet or mat, and so forth and so on. Each of those sticky sheets or mats 24A can be of any suitable construction. Examples of suitable sheets or mats are the cleanroom sticky mats sold by Blue Thunder Technologies (www.bluethundertechnologies.com) under the trademark THUNDER MATS, or the floor mats sold by Markel Industries (http://markelind.com/about/) under the trademark Trim Tack. In either case the sheets or mats 24A that make up the stack 24 include the tacky coating or adhesive on their undersurface, not their top surface.

[0027] Each of the clips 30 is of identical construction and a respective one of each of the clips 30 is mounted on a respective sidewall section and extends downward therefrom as best seen in FIG. 1. As best seen in FIG. 2, each of the clips 30 is in the form of a downwardly projecting finger 30A terminating in an inwardly directed free end flange 30B. The effective height of the clip, i.e., the distance between the bottom wall 26 and the inner surface of the flange 30B is just slightly greater than the thickness of the table top 16. Each clip 30 is configured to be flexed outward to enable the inwardly directed flange to snap-fit under the bottom surface of the table top 16 to releasably mount the device 20 on the table top.

[0028] With the device 20 mounted on the table top, the uppermost mat 24A of the stack 24 will be exposed through the open window 34 to provide a sanitary surface on which objects such as food, medications, supplies and equipment can be placed. When it is desired to dispose of the uppermost mat 24A, e.g., it is soiled, it can be removed from the stack, by peeling it off of the underlying mat through the window like shown in FIG. 1, whereupon the removed mat can be discarded, thereby leaving the sanitary upper surface of the underlying mat exposed through the open window to serve as a fresh sanitary surface upon which objects can be placed. The usage of the device 20 will be described in more detail later.

[0029] Attention is now directed to FIGS. 3-5, wherein another preferred embodiment 120 of the device of this invention is disclosed. The device 120 is virtually identical to the device 20 except for the inclusion of a slot in the housing or case (to be described shortly) and the use of a stack of non-tacky mats or sheets (also to be described shortly) in lieu of the stack of tacky mats or sheets. In the interest of brevity those components of the device 120 which are identical in construction and operation to the like components of the device 20 will be given the same reference numbers and their description and operation will not be reiterated.

[0030] Thus, as can be seen in FIG. 5, a stack 124 of non-tacky mats or sheets 124A is located within the hollow interior chamber 36 of the housing or case 122. The housing or case 122 includes an elongated slot 126 in the side wall section making up one of the end wall sections of the housing or case 122. The slot 126 is in communication with the hollow interior chamber 36 and hence the stack 124 of non-tacky mats or sheets. The slot 126 serves as the place from which the uppermost mat of the stack is removed by a user when a new mat is to be used to form a sanitary surface for objects. That action is accomplished by a user pressing down on the uppermost mat 124A through the open window 34, and sliding that mat out through the slot 126, to expose the underlying mat in the window. In the interest of facilitating the removal of any mat from the stack 124 the upper surface of each of the mats 124A of the stack may include indicia thereon indicating that the sheet is to be pressed downward through the window and out through the slot. To that end, such indicia may be like the icon of a hand with an arrow pointing in the direction that the mat is to be slid, like shown in FIGS. 3 and 4.

[0031] Since the mats or sheets of the stack 124 is to be slid out of the slot 126, and not peeled off the stack and removed through the open window 34, the stack 124A of mats is like the stack 24, but each sheet or mat 124A does not include any tacky coating or adhesive on its undersurface (or its upper surface for that matter). This construction enables the uppermost sheet or mat of the stack to be readily slid off the underlying sheet or mat, without interference of a tacky coating or adhesive.

[0032] The devices 20 and 120 or any other devices constructed in accordance with the subject invention can be used in various ways. For example, they can be used by nurses or technicians to prepare a preparation surface for their supplies. In particular, with a device 20 constructed like that of FIGS. 1 and 2 (or a variant thereof) mounted on the over-bed table in a patient's room, the nurse or technician can simply peel off and discard the top mat 24A of the device, leaving a clean underlying mat exposed through the device's window to serve as a fresh sanitary surface on which they can place their supplies and patient medications. This action when accomplished will create an instantly clean surface for such objects without necessitating the use of chemical solutions or wipes. The user simply peels away the top (uppermost) soiled mat of the device, leaving behind a clean surface on the underlying mat.

[0033] Similarly, with a device 120 constructed like that of FIGS. 3-5 (or a variant thereof) mounted on the over-bed table 10 in a patient's room, the nurse or technician can simply press down on the uppermost mat that is exposed in the open window 34 and slide that mat in the direction of the arrow shown in FIGS. 3-4 so that the mat is ejected out the slot 126, thereby leaving a clean underlying mat exposed through the device's open window to serve as a sanitary surface on which they can place their supplies, patient medications, etc.

[0034] The devices of this invention can also be used for meal preparation. In such use, the device is mounted on the over-bed table with its uppermost mat serving as the surface on which the patient's food is placed. When that mat becomes dirty, the nurse, staff member, or even the patient can peel away the top mat (if using the embodiment 20 of FIGS. 1 and 2) or slide away the top mat (if using the embodiment 120 of FIGS. 3-5), thereby leaving a clean underlying mat exposed to serve as the surface to eat on or place objects on.

[0035] It should be pointed out at this juncture that the exemplary embodiments shown and described heretofore are merely examples of many devices that can be constructed in accordance with this invention for holding a stack of sanitary mats on an over-bed table. For such uses the mats may be of 30 inch by 15 inch size to fit the most common size of patient over-bed tables. It should also be noted that the devices of this invention are not limited to use solely on over-bed tables. Thus, they can be used on any table or surface for which a clean sanitary surface is desired. For example, the mat can be placed on the work counter for human milk and formula preparation in the Neonatal Intensive Care Unit (NICU). Moreover, it is contemplated that the subject invention may merely make use of a stack of sanitary mats, without any case or housing for the stack. In such use the stack of mats would be directly releasably mounted on the top surface of a table or counter. In such a case the undersurface of at least the lowermost of the mats or sheets of the stack should be of a higher grade adhesive than the adhesive between the mats/sheets so that the stack effectively sticks to the table. Moreover, it is contemplated that for an embodiment of the invention making use of tacky mats/sheets to expedite removal of the uppermost mat/sheet, a corner of the that mat/sheet (approximately 1 inch1 inch) would not not have releasable adhesive on it. Therefore the user can use this corner as a pull tab to lift and peel that mat/sheet off of the stack. That corner could include indicia indicating the existence of the pull tab. Examples of such indicia may be the words PULL HERE or the corner could be a different color. It is also contemplated that the mat/sheets be treated with a indicating agent which would change color after exposure for a certain period of time to indicate that it is time for the exposed mat/sheet to be changed.

[0036] Without further elaboration the foregoing will so fully illustrate my invention that others may, by applying current or future knowledge, adopt the same for use under various conditions of service.
