The disclosure relates to dispensers and lockable pushbuttons.
Hand washing is important in many industries, including hospitality (hotels, restaurants, etc.) and healthcare (hospitals, nursing homes, etc.). To facilitate hand washing, hand soap dispensers are placed near sinks for the washing of hands by employees of such establishments. In addition, public restrooms typically include hand soap dispensers used by patrons of an establishment, patients of a healthcare facility, or other members of the public. These dispensers house a disposable or refillable product container, such as a cartridge or flexible bag, containing a supply of the desired soap product. The soaps may include foam, liquid and/or gel hand soaps. The dispensers are generally wall mounted and include a hinged cover which permits opening and closing of the dispenser housing so that the supply of soap may be refilled or replaced. Some hand soap dispensers are manually actuated by pushing or pulling a handle, bar, or button on the dispenser. Others dispense automatically by sensing presence of a user's hands near the dispenser.
In general, the disclosure relates to lockable pushbuttons. The lockable pushbuttons may be used with any application, such as a hand soap dispenser or other application in which a lockable pushbutton may be desirable. A locking mechanism is configurable to provide a pushbutton locked position and a pushbutton unlocked position. When the locking mechanism is positioned in a locked orientation, the locking mechanism prevents actuation of the pushbutton. When the locking mechanism body is positioned in an unlocked orientation, the locking mechanism permits actuation of the pushbutton.
In one example, the disclosure is directed to a lockable pushbutton, comprising a locking mechanism body having a locked orientation and an unlocked orientation, a locking mechanism receiving area sized to receive the locking mechanism in either the locked orientation or the unlocked orientation, and an actuatable pushbutton, such that when the locking mechanism body is received into the locking mechanism receiving area in the locked orientation, the locking mechanism prevents actuation of the pushbutton, and when the locking mechanism body is received into the locking mechanism receiving area in the unlocked orientation, the locking mechanism permits actuation of the pushbutton.
In another example, the disclosure is directed to a housing including a back plate and an openable front cover, a container inside of the housing having a supply of fluid to be dispensed, a dispensing actuator that when actuated by a user results in a quantity of the fluid being dispensed from the container, a locking mechanism body having a locked orientation and an unlocked orientation, the housing further including a locking mechanism receiving area positioned inside of the housing and sized to receive the locking mechanism in either the locked orientation or the unlocked orientation, and a lockable pushbutton that upon actuation depresses a latch inside of the housing thus allowing the front cover to be opened, such that when the locking mechanism body is received into the locking mechanism receiving area in the locked orientation, the locking mechanism prevents actuation of the pushbutton, and when the locking mechanism body is received into the locking mechanism receiving area in the unlocked orientation, the locking mechanism permits actuation of the pushbutton.
In another example, the disclosure is directed to a lockable pushbutton comprising a housing including a pushbutton receiving area having a base and substantially vertical sidewalls, the base further including an aperture and a slot, the slot having a locking detent at a first end and an unlocking detent at a second end, a locking stop including a stop body having a first interlock post at a first end and a second interlock post at a second end, wherein first interlock post fits into the aperture and the second interlock post fits into the slot such that second interlock post is movable within the slot between the locking detent and the unlocking detent, and an actuatable pushbutton sized to fit within pushbutton receiving area, the aperture and the slot positioned within the base such that when the second interlock posts is positioned in the locking detent, the stop body blocks the aperture and prevents actuation of the pushbutton.
In another example, the disclosure is directed to a dispenser, comprising a housing including a back plate and an openable front cover, a container inside of the housing having a supply of fluid to be dispensed, a dispensing actuator that when actuated by a user results in a quantity of the fluid being dispensed from the container, the housing further including a pushbutton receiving area having a base and substantially vertical sidewalls, the base further including an aperture and a slot, the slot having a locking detent at a first end and an unlocking detent at a second end, a locking stop including a stop body having a first interlock post at a first end and a second interlock post at a second end, wherein first interlock post fits into the aperture and the second interlock post fits into the slot such that second interlock post is movable within the slot between the locking detent and the unlocking detent, and an actuatable pushbutton sized to fit within pushbutton receiving area the aperture and the slot positioned within the base such that when the second interlock posts is positioned in the locking detent, the stop body blocks the aperture and prevents actuation of the pushbutton.
The details of one or more examples are set forth in the accompanying drawings and the description below. Other features and advantages of the invention will be apparent from the description and drawings, and from the claims.
Hand soap dispensers, such as example dispenser 100, are generally placed near sinks in kitchens, hospitals, restrooms, or other locations to facilitate hand washing by employees, members of the public, or other users. In some applications, it may be desirable to provide a hand soap dispenser that prevents such users from opening the dispenser housing and obtaining access to the interior of the dispenser. This may help to prevent theft of the product supply container, and/or tampering with the product supply or the inner workings of dispenser 100.
In other applications, various fluids may be dispensed using a manual or automatic dispenser. The fluid to be dispensed may include, for example, one or more of a hand soap, a lotion, a sanitizer, a disinfectant, or any type of cleaning agent. The fluid to be dispensed may also include one or more of a detergent, a bleach, or other type of laundry product. In general, the lockable pushbutton(s) described herein may be used in any application in which a lockable pushbutton may be desired, and the disclosure is not limited in this respect.
Example dispenser 100 is provided with a lockable pushbutton 150. Lockable pushbutton 150 includes a locking mechanism (not shown in
Housing 110 of dispenser 100 includes, as discussed above, a cover 102 and a back plate 104. A catch 168, in combination with a latch on cover 102, holds cover in a closed position with respect to back plate 104. Housing 110 further includes a pushbutton receiving area 170 having sidewalls 151 and a base 152. Base 152 includes an aperture 154 and a slot 156. Slot 156 includes a detent 158A at a first end and a detent 158B at a second end. A locking stop 160 includes a stop body 161 having a first interlock post 162A at a first end and a second interlock post 162B at a second end. First interlock post 162A fits into an interlock aperture 166 in base 152. Second interlock post 162B fits into slot 156. As such, locking stop 160 may rotate between the unlocked position shown in
In this example, first and second interlock posts 162A and 162B are flexible so that they may be fit into interlock aperture 166, and slot 156. The flexible interlock posts 162B permits locking body 160 to rotate between the unlocked and locked positions (e.g., detents 158A and 158B, respectively) and provide positive feedback to the user that the stop is correctly placed in either the locked or the unlocked position.
The lockable pushbutton shown in
Locking mechanism 202 is configured to be insertable in two different orientations into the corresponding locking mechanism receiving area; a lock orientation and an unlock orientation. For example, to place the dispenser in a locked configuration, locking mechanism 202 may be inserted into the receiving area in an orientation in which the locking projections 206A and 206B are orientated toward the lockable pushbutton of the dispenser. That is, in this example, locking mechanism 202 would be inserted into the locking mechanism receiving area in the orientation shown in
Alternatively, to place the dispenser in an unlocked configuration, locking mechanism 202 may be inserted into the receiving area in an orientation in which the unlocking projections 208A and 208B are orientated toward the lockable pushbutton of the dispenser. That is, in this example, locking mechanism 202 would be inserted into the locking mechanism receiving area in the orientation shown in
In this way, example locking mechanism 202 provides a one piece design that is reversible to provide both locking and unlocking functions for a lockable pushbutton. In a first orientation (such as that shown in
Locking mechanism 202 may be inserted into receiving area 230 such that base 218 is fitted into receiving space 209. In this example, locking projections 206A and 206B, as well as unlocking projections 208A and 208B are shaped to receive spring recess 214 when locking mechanism 220 is inserted into receiving area 230.
In the examples shown in
Although specific examples of a lockable pushbutton, locking mechanisms for a lockable pushbutton have been described, it shall be understood that other variations of lockable pushbuttons and locking mechanisms may also be used without departing from the spirit and scope of the present disclosure. In addition, although the lockable pushbutton and locking mechanisms are described herein with respect to a hand soap dispenser, it shall further be understood that the lockable pushbutton and locking mechanisms such as those described herein may also be used in other applications in which a lockable pushbutton may be desired. Those of skill in the art will readily appreciate that many alternative designs may be used, and that the disclosure is not limited in this respect.
Various examples have been described. These and other examples are within the scope of the following claims.
This application claims the benefit of U.S. Provisional Application No. 61/640,890, filed May 1, 2012, which is incorporated herein by reference in its entirety.
