The invention is directed to a latch for a stall in a bathroom. More particularly, embodiments of the invention are directed to a latch for a stall in a bathroom that is operable without the user using their hands.
An example of an application for the invention is a hands free latch in a stall of a commercial bathroom, where a user of the stall can easily close and open the latch without using either of their hands.
Many buildings, such as, for example, commercial office buildings or other commercial buildings, have bathrooms containing one or more stalls that partition a toilet from the rest of the bathroom. The stall often has a latch that the user of the stall operates to lock the stall door so that other people cannot open the door while the user is in the stall.
Latches are primarily used for the purpose of locking doors. Normal latches are locked manually from inside for the purpose of securing the door. Restricted toilet facilities like aircraft toilets and train toilets typically have normal latches installed on them. A problem arises when a person enters a toilet having a normal latch and is required to touch an unsanitary stall latch.
A conventional toilet latch needs to be manually operated by the person inside the toilet in order to secure the door. Conventional latches are manually moved from an unlocked position to a locked position when the door on which the latch is mounted, is closed.
However, even such a mechanism requires that the door is pushed from its open position towards a closed position. This movement requires user intervention to perform this action. The areas touched by the user are likely not sanitized.
Applicant recognized an improvement to the above arrangement and implements that improvement in embodiments of the invention.
Many buildings, such as, for example, commercial office buildings or other commercial buildings, have bathrooms containing one or more stalls that partition a toilet from the rest of the bathroom. The stall often has a latch that the user of the stall operates to lock the stall door so that other people cannot open the door while the user is in the stall. The latch is often touched by a user of the stall after the user has used the toilet and before the user has access to a sink to wash their hands. As a result, the latch is often contaminated with fecal matter, viruses, and/or other unhealthy and/or undesirable material.
The invention achieves the benefit of allowing the user of the stall to close and open the latch without having to contact the latch with their hands. In embodiments of the invention, this benefit is achieved by configuring a handle of the latch such that the latch is operable by the user with the user's forearm. Embodiments also provide the benefit of allowing a user to easily operate the latch even if the user does not have hands or have the use of their hands.

The attached figures form part of the present specification and are included to further demonstrate certain aspects of the disclosed features and functions, and should not be used to limit or define the disclosed features and functions. Consequently, a more complete understanding of the exemplary embodiments and further features and advantages thereof may be acquired by referring to the following description taken in conjunction with the accompanying drawings.
The invention is described herein with reference to the accompanying drawings in which exemplary embodiments of the invention are shown. The invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein.
As explained above, embodiments of the invention are directed to a latch for a stall in a bathroom that is operable without the user using their hands.
An object of embodiments of the invention is to reduce the transmission of germs in public restrooms by eliminating the need to use hands to open the stall door. Embodiments include a wrist pull to eliminate the need for touching the door to open or close the door. In embodiments, the wrist pull protrudes out from the sliding base or bracket so the user can insert their wrist or forearm in the space between the door and the protrusion to lock the latch and to pull the door from a closed position to an open position.
The inclusion of a small instruction sheet pasted to the stall door mitigates the risk of hands being used due to confusion. Embodiments are simple to install in existing restrooms, as the sliding latch is easy to retrofit to stall doors.
Embodiments are American with Disabilities Act (ADA) compliant and are simple to install in new and/or retrofit situations. Embodiments extend into the stall in a similar fashion to a coat hook. ADA specifications were considered to determine how far the bar could protrude into the stall. Due to the shape and angle of particular embodiments of the latch, embodiments are capable of withstanding a weight of 50 pounds hung on the latch. In embodiments, the protruding wrist pull extends no further than 3.25 inches into the stall.
An exemplary embodiment of a sliding latch assembly 10 is shown in
Another advantageous feature of embodiments is the height that the latch should be placed on the door. Because, in embodiments, a forearm of a user is user to operate sliding latch 100, it is advantageous for the latch to be installed higher than a normal hand operated latch. Research shows that the average female and male in the United States is about 64″ and 69″, respectively. Further, ADA compliance states that a coat hanger attached to the back of a stall door should be installed “54 inches above the finished floor for a side approach” (ADA Regulations, 1991). In embodiments, this and other information is used to ensure that ADA guidelines are met. For example, in embodiments, the latch is placed 54″ above the floor of the stall. Other installation heights can also be used.
Due to the structure and placement of sliding latch 100, a consideration is the possibility of a person either hanging or placing a bag or other object on the latch. In embodiments, a middle section 120 of sliding latch 100 that extends into the stall is tapered to create an angled upper edge 126 (as shown in
As shown in
Embodiments of the invention are manufactured from a material that is able to function in a wide variety of temperatures and environments. Embodiments of the invention use aluminum 6061 (a heat-treated aluminum alloy consisting of magnesium and silicon). This alloy of aluminum has a high corrosion resistance, meaning it can exist in any temperament, and is relatively inexpensive. Further, research shows that germs reside on aluminum for four hours while they can live on stainless steel for 72 hours. Although an object of the invention is to reduce the transmission of germs by providing a hands-free solution, it can be beneficial to use a material that supports germ life for a relatively shorter period of time. Other non-limiting examples of suitable materials include zinc alloys such as, for example, Zamak, and stainless steel.
With the described shape of sliding latch 100, it is likely that some users will attempt to hang a heavy object, such as a book bag, on front section 130 and/or middle section 120 of sliding latch 100. In embodiments, sliding latch 100 is 0.25 inches thick and is mounted to door 20 with bracket 200 which has a total tolerance of 2 mm in the vertical direction. Despite the countermeasure of tapered middle section 120 and front section 130 to promote the sliding off of any item and prevent the users from hanging bags or heavy items that might adversely affect the product, there still exists a risk that this measure does not work. To help ensure that sliding latch assembly 10 will not undergo failure with a downward force acting on the top surface of sliding latch 100, a sufficiently strong structure is provided. For example, embodiments support a weight of 50 pounds.
In embodiments, sliding latch 100, bracket 200, and latch catcher 300 all have a fillet of 0.05 in along the edges to help reduce risk to the user. Door stopper 400 utilizes a filler of 0.025 due to size constraints, and because it is unlikely that users will have any contact with it. In embodiments, a tolerance of +/−0.025 inches was applied to each piece to ensure the parts properly function with each other.
While the above embodiments were described with sliding latch 100 attached to door 20 and latch catcher 300 attached to stall wall 30, it is noted that other embodiments include sliding latch 100 attached to stall wall 30 and latch catcher 300 attached to door 20.
An alternate embodiment shown in
While the above embodiments were described with pivoting latch 1100 and mounting member 1200 attached to the door and latch catcher 300 and door stopper 400 attached to the stall wall, it is noted that other embodiments include pivoting latch 1100 and mounting member 1200 attached to the stall wall and latch catcher 300 and door stopper 400 attached to the door.
It will be appreciated that variants of the above-disclosed and other features and functions, or alternatives thereof, may be combined into many other different systems or applications. Any of the features described above can be combined with any other feature described above as long as the combined features are not mutually exclusive. Various presently unforeseen or unanticipated alternatives, modifications, variations or improvements therein may be subsequently made by those skilled in the art which are also intended to be encompassed by the invention.
The application claims the benefit of the filing date of U.S. Provisional Patent Application No. 63/121,065 filed Dec. 3, 2020, the disclosure of which is incorporated in its entirety by reference herein.
