Washrooms in commercial and residential buildings typically include products such as toilet tissue, paper towels, diapers, feminine products, liquid products such as soap, and aerosol products such as air fresheners. These products are typically housed by a dispenser and are dispensed as needed by the user.
However, these dispensers are often ubiquitous in appearance offering only a few, if any, styling options during the purchase process. For example, if a building owner desires to update the décor of a washroom it is often necessary to remove the dispenser, which can damage the wall from which the dispenser was hanging and necessitate repairs (and discarding a perfectly good dispenser), and buy and install another dispenser better matched to the updated décor. This is an expensive and labor-intensive process.
In general, the present disclosure is directed to a dispenser for a sheet material, such as paper towels, that has a modular front plate design that can be installed and/or removed at the end-user level including for installed dispensers, e.g., without having to removing dispensers from the walls on which they are mounted. The modular dispenser front plate design, for instance, can be modified only by access to the interior of the housing of the dispenser and can have a variety of different external materials/aesthetics.
In one aspect, the disclosure is directed to a dispenser for sheet materials comprising a housing having an interior volume configured to hold sheet material, the housing primarily made from plastic and including a cover assembly, wherein the cover assembly comprises a back frame member comprising a first side and a second and opposite side, the second side of the back frame member forming an interior surface of the housing, and the first side of the back frame member comprising at least one mating receptor; and a plate comprising a carrier member primarily made from plastic and a decorative facia, wherein the carrier member has a facia side coupled to the decorative facia and a back and opposite side, including a locking element, wherein the plate is configured to be removably coupled to the first side of the back frame member when the locking element of the carrier member is releasably engaged to the mating receptor of the back frame member such that the decorative facia forms an exterior surface of the dispenser. Other aspects include corresponding methods.
In another aspect, the disclosure is directed to a method comprising opening a cover of a dispenser housing of a dispenser, wherein the dispenser housing has an interior volume configured to hold sheet material, wherein the housing is made primarily from plastic and wherein the cover comprises a back frame member comprising a first side and a second and opposite side, the second side of the back frame member forming an interior surface of the housing, and the first side of the back frame member comprising at least one mating receptor; and removing a front plate, comprising a carrier member primarily made from plastic and a decorative facia, from the cover, wherein the carrier member has a facia side coupled to the decorative facia and a back and opposite side, including a locking element, and the front plate is releasably attached to the first side of the back frame member when the locking element of the carrier member is engaged to the mating receptor of the back frame member such that the decorative facia forms an exterior surface of the dispenser. Other aspects include corresponding systems.
Dispensers made with the above features include many advantages. For example, a dispenser with the above features can change its appearance after it has been installed, e.g., mounted to a wall, by replacing its front cover (or other portion of its housing or all of its housing) with another that has a different design, pattern or appearance. In some instances, this replacement can be accomplished in a single motion to aid the attendant changing covers to do so without undue difficulty.
Historically, changing the appearance of a dispenser would have required removal and replacement of the dispenser, which is costly and often necessitated repairs to the wall where the old dispenser had been mounted (e.g., by screws or adhesive). In contrast, the inventive dispenser described herein can have its aesthetic changed by simple replacement of, for example, the cover, as opposed to the entire dispenser, without need to remove the dispenser from its mounts and possibly repair any damaged caused by such removal.
Other features and aspects of the present disclosure are discussed in greater detail below.
A full and enabling disclosure of the present disclosure is set forth more particularly in the remainder of the specification, including reference to the accompanying figures, in which:
Repeat use of reference characters in the present specification and drawings is intended to represent the same or analogous features or elements of the present invention.
It is to be understood by one of ordinary skill in the art that the present discussion is a description of exemplary embodiments only, and is not intended as limiting the broader aspects of the present disclosure.
The present disclosure is generally directed to a dispenser for consumable products (e.g., sheet materials such as paper towels and bath tissue and liquid soaps and sanitizers) and/or to a dispenser assembly. The dispenser of the present disclosure allows for flexibility in design offerings and functionality without having to change the entire dispenser system. More particularly, the present disclosure is directed to a dispenser for sheet materials with a modular dispenser front plate and/or shroud design that can be installed at the end-user level. In accordance with the present disclosure, the dispenser is configured to include an exchangeable front plate and/or shroud that can change the aesthetic appeal and/or functionality of the dispenser. For instance, the dispenser includes a front plate that forms the front face and external surface of the dispenser which can be easily switched out and replaced. For example, a user can select a front plate that has a particular desired look and/or can install or replace a front plate with one that can include electronic hardware that can enable various tiered functionality, such as lighting and connectivity.
In one embodiment, the dispenser includes at least a two-part housing having a front cover and a back cover. The front cover can be pivotably connected to the back cover for opening and closing the housing. The front plate assembly and/or shroud of the present disclosure can be integrated into the front of the housing and can be designed such that the front plate and/or shroud can only be removed and replaced by having access to the interior of the housing.
Referring particularly to
The dispenser configuration 10 illustrated in the figures is merely exemplary for any number of dispenser configurations known to those skilled in the art that may incorporate the front plate assembly of the present disclosure. As such, a detailed explanation of the structural and control features of the dispenser 10 are not necessary for purposes of explanation of the system and method of the present disclosure, and will only be discussed briefly below.
The operational components of the dispenser 10 may be mounted directly to the back cover 18 or can be part of a module that is received within the housing 16. For example, the operational components can be part of a module that may be readily removable from the housing for servicing and/or replacing components without the necessity of having to remove the entire dispenser 10 from its support surface.
As shown in
Left and right main roll holders 30 are attached within the housing and hold the main roll 12 of sheet material. Stub roll holders may be provided for rotatably supporting the stub roll 14 in the position within the housing below the main roll 12. It should be understood that a dispenser according to the present disclosure need not be configured to dispense from a stub roll, and thus would not need a transfer mechanism. The dispenser may be configured for dispensing from a single roll of sheet material.
The pressure roller 46 may be housed within the throat assembly 50 that is, in turn, mounted within the housing. The dispenser 10 may also include a tear bar or cutting bar that is contained within the throat assembly 50 and disposed along the dispensing path of the sheet of material upstream from the dispensing opening 20 and downstream of the nip between the drive roller 38 and the pressure roller 46. To separate a sheet of material that has been dispensed from the dispenser 10, the cutting bar can automatically cut the material or, alternatively, a user can grasp a sheet hanging from beneath a bottom portion of the housing and pulls the sheet against the cutting or tear bar such that the sheet tears and separates along a line defined by the tear or cutting bar.
In some embodiments, the pressure roller 46 is spring biased against the drive roller 38 such that the sheet of material passing between the nip of the rollers is advanced along the dispensing path upon rotation of the drive roller 38. The throat assembly 50 defines a portion of the dispensing path and the forward portion of the dispensing throat 24. The dispenser 10 may further include an automatic transfer mechanism to transfer dispensing of the sheet of material from the stub roll 14 to a main roll 12 when the sheet of material on the stub roll 14 is nearly depleted. Any suitable transfer mechanism may be used. For example, the transfer mechanism may include a transfer bar 56 with arms pivotally mounted. The transfer bar 56 includes a roller section that may be defined by a central curved rib section. The rib section includes a securing mechanism, such as a barb, so that the leading end of the sheet of material from the main roll 12 passes over the rib section and is held by the barb while material is fed from the stub roll 14. The dispenser 10 can also include a stub roll sensing device, such as a sensing bar that is biased towards the axis of the stub roll holders so as to track the decreasing diameter of the stub roll as it is depleted. Alternatively, an electronic sensor can also be used to monitor the stub roll.
The dispenser 10 can also include a spring biased bar 40 that is pivotally mounted within the housing 16 and biased towards the center of the main roll 12 such that the bar 40 tracks a decreasing diameter of the main roll 12 as the sheet of material is depleted. Again, instead of a spring biased bar 40, any suitable electronic sensor may also be used. When the main roll 12 reaches a diameter suitable for moving the roll 12 to the stub roll position, the dispenser 10 can include suitable mechanical elements for moving the main roll 12 into place for dispensing the sheet of material.
The drive roller 38 can be placed in communication with a drive motor and gear assembly. The motor can include a drive shaft and a drive gear attached thereto that engages the shaft of the drive roller 38. Thus, upon energizing the motor, the drive roller 38 is caused to rotate, which results in conveyance of the sheet of material disposed in the nip between the pressure roller 36 and the drive roller 38 along the conveying path and out of the dispensing throat 24.
The dispensing mechanism may be powered by batteries contained in a battery compartment or can be powered by an AC distribution system. If the dispenser 10 includes batteries, a sensor can also be included for determining the power level of the batteries.
As described above, the dispenser 10 can include a controller and control circuitry. The controller and control circuitry can control and monitor all the functions of the dispenser 10 including the length of the sheet of material being dispensed, product usage, and any other activities that are occurring within the dispenser. The controller can be configured to communicate information regarding the dispenser 10 to a central control system via wired means or through a web-based system.
In one embodiment, the dispenser 10 can include a sensor that is designed to detect the presence of a user in a detection zone. Once the presence of a user is detected, the dispenser 10 can be configured to automatically dispense the sheet product. For example, the dispenser 10 can include an infrared sensor to detect when an object, e.g., a user's hand, passes through its sensing zone to trigger the motor to actuate a dispense cycle to deliver sheet material out the throat 24 to the user.
In accordance with the present disclosure, the front cover 22 of the dispenser 10 includes a front plate assembly (also referred to as a cover assembly 22 or a front cover assembly 22) as shown in
As shown in
The front plate 60, through its second side 66, is removably attachable to the back frame member 62. For example, the back frame member 62 can include a first side 68 as shown in
The first side 68 of the back frame member 62 forms an interior surface within the dispenser 10. The second side 70 of the back frame member 62, on the other hand, can releasably attach to the second side 66 of the front plate 60. For example, the second side 66 of the front plate 60 can include a plurality of locking elements 72 and one or more alignment tabs 74. In the embodiment illustrated in
As shown in
As shown in
In some embodiments, as shown in
As shown in
In order to remove the front plate 60 from the back frame member 62, the back frame member 62 can include one or more push pins 86 as shown in
Further, in some embodiments, with or without the raised margin area 84, as shown in
Further, once the pair(s) of mating receptor(s) 78 and locking element(s) 72 are engaged, as shown in
To remove the plate 60 from the housing 16, for example, to replace the current plate 60 with a plate 60 having a different aesthetic design, a user disengages the locking tabs 80 from the alignment slot(s) 76, as shown in
In addition, as described above, in order to remove the front plate 60, one would need to open the dispenser housing 16 in order to access the locking tabs 80. Having the locking tabs 80 located on the interior surface of the housing 16 prevents against inadvertent removal of the front plate 60 and allows removal of the front plate 60 only when the housing 16 is unlocked and opened (e.g., by an authorized service attendant).
In addition to mechanically connecting the front plate 60 to the back frame member 62, the dispenser 10 can also be configured so that the front plate 60 becomes electrically connected to a controller and a power supply within the dispenser 10 when attached to the back frame member 62. For example, in one embodiment, the locking elements 72 and the mating receptors 78 may create an electrical connection in addition to a mechanical connection using appropriate wiring. In an alternative embodiment, the front plate assembly can include electrical conduits 88 that extend from the second side 66 of the front plate 60 as shown in
In this regard, the front plate 60 can have electronic functionality. For example, the front plate 60 may comprise an electronic display, capable of displaying graphics and images. In addition, the front plate 60 can be equipped with an audio speaker for emitting music, instructions, news, or any other information. In one embodiment, for instance, the front plate 60 can be connected to a controller for displaying television or cable channels, commercials, or any other media content.
In other embodiments, the front plate 60 may be designed to provide an overall look or appearance. For instance, in
In one embodiment, the present disclosure is directed to a dispenser assembly that includes a dispenser as shown in
In some implementations, as described above, the dispenser 16 includes a front cover 22. In some implementations, with reference to
In some implementations, the frame 92 includes mating receptors 99 (similar to mating receptors 78) and the shroud 101 includes locking elements (not shown) similar to locking elements 72 to hold the shroud 101 on the frame 92, preferably such that the shroud 101, like the plate 60, can only be removed when the dispenser 10 is open, e.g., by an authorized service attendant. In some implementations the shroud 101 also (or alternatively) is attached to the frame 92 through screws, bolts or other mechanical fasteners or adhesives or the like, but, in any event, designed to be removable to change shrouds 101.
In some implementations the plate 60 and/or shroud 101 are made from a biodegradable and/or compostable material such as or including a cellulosic material. Preferably the plate 60 and/or shroud 101 could be made from a moldable (e.g., through an injection molding process), biodegradable material.
These and other modifications and variations to the present invention may be practiced by those of ordinary skill in the art, without departing from the spirit and scope of the present invention, which is more particularly set forth in the appended claims. In addition, it should be understood that aspects of the various embodiments may be interchanged both in whole or in part. Furthermore, those of ordinary skill in the art will appreciate that the foregoing description is by way of example only, and is not intended to limit the invention so further described in such appended claims.
