The present invention relates generally to urinal accessories, and, more particularly, relates to a urinal anti-splash device for placement within a urinal.
A urinal, often installed for efficiency when compared to a general purpose toilet, is a sanitary plumbing fixture commonly located in male restrooms. The use of a urinal, in comparison to a general purpose toilet, is often more convenient for a user due to the absence of additional doors and locks. As an added convenience, urinals do not require a user to turn up a seat prior to use, which is both convenient and generally more sanitary than the toilet. Moreover, urinals occupy less space and consume less water per flush, or possibly no water at all, than a toilet which requires flushing.
Devices designed to be placed within urinals are well-known. For example, urinals found in public restrooms often have a plastic mesh guard to prevent large debris from entering the drain. Unfortunately, such plastic mesh guards fail to reduce or prevent the splashing of urine onto the user. In fact, such plastic mesh guards may actually increase the risk of the user being splashed by the urine as the urine ricochets from the plastic mesh guard. Moreover, these plastic mesh guards do not prevent the splashing of urine that is directed towards the back wall of the urinal.
Other known devices designed to be placed within urinals, often referred to as urinal screens or occasionally as urinal mats, are sized and shaped to cover either the urinal's back wall or the drain. Such urinal screens do not allow the user the option of covering both the back wall and the drain to prevent the urine from splashing onto the user from a maximum surface area of the urinal. Moreover, some urinal screens are made of a rigid material that may fail to conform to the various sizes and shapes of urinals.
Additional known devices designed for placement within a urinal often include protrusions that are densely compacted together, preventing a urine stream from flowing in a vertical direction toward the urinal screen. In this vein, such devices rely on the protrusions to break up the urine stream, leaving urine deposited on the protrusions, resulting in an unpleasant odor and the need for increased cleaning frequency of the device. Moreover, many urinal screens include urinal cakes or deodorizers which require costly and frequent replacement.
Therefore, a need exists to overcome the problems with the prior art as discussed above.
The invention provides a urinal anti-splash device that overcomes the hereinafore-mentioned disadvantages of the heretofore-known devices and methods of this general type and that provides a urinal anti-splash device sized and shaped to mate with a urinal back wall and a urinal screen to prevent urine from splashing on a user when urine is deposited in the direction of the urinal back wall and/or the urinal screen.

Referring now to
In one embodiment, the portion of the urinal 102 configured to receive the anti-splash body 104 is a back wall 114 of the urinal 102. In one embodiment, the back wall 114 may include a height of approximately 17.0-22.0 inches in length and a width that is approximately 9.0-14.0 inches in length. In other embodiments, the urinal 102 may include a length and a width that is outside of this range.
In one embodiment, the anti-splash body 104 includes an elongated shape of a flexible material configured to couple to the urinal 102. The term “elongated” is defined herein as having a length that is at least twice as long as a width. In other embodiments, the length may be less than twice as long as the width. For example, in one embodiment the length 112 is approximately 17.0-20.0 inches. In this embodiment, the anti-splash body may include a width 116 that is approximately 5.0-8.0 inches. In another embodiment, the length 112 may be approximately 13.0-16.0 inches and the width 116 may be approximately 3.0-6.0. In other embodiments, the length 112 and the width 116 may be outside of these ranges.
In one embodiment, the anti-splash body 104 may be made of a material that is flexible and tough, such as DuPoint Elvax®250, PVC plastic, or the like. In other embodiments, the anti-splash body 104 may be composed of a composite material, a metallic material, or another material conducive for placement within a urinal. The material may or may not have elastically deformable properties (e.g., the ability to change its shape and return back to its static-state shape after its change in shape). In one advantageous embodiment, the material is a buoyant material that provides a base 106 that will rise above the water line where water remains in the urinal after flushing, thereby decreasing the risk of the urinal drain being blocked by the anti-splash device 100. In other embodiments, the material may be a non-buoyant material.
In one embodiment, the urine is prevented from splashing onto the user when striking the anti-splash body 104 at least partly due to a first plurality of protrusions 118 being coupled to an front surface 120 of the anti-splash body 104. The term “protrusion” is defined herein as a part that extends away from the front surface 120 and may include bristles, a wave pattern, one or more shapes, e.g., squares, or another configuration designed to prevent urine from splashing onto a user when using the anti-splash device 100. In use, such as when a urine stream strikes the protrusions 118, the urine may be broken apart by the protrusions 118. Said another way, the anti-splash device 100 may not rely on a capillary action to reduce or prevent urine from splashing from the anti-splash device 100 onto a user.
Advantageously, the protrusions 118 define a plurality of protrusion voids 122 which permit the urine to effectively flow in a downward direction along the front surface 120 toward the lower portion 124 of the urinal 102 which houses the urinal drain. In one embodiment, such as when the device 100 is disposed in a vertical direction with respect to the back wall 114 of the urinal 102, gravity may assist in causing the urine to effectively flow in the downward direction toward the lower portion 124 of the urinal 102. The protrusion voids 122 may also provide space for the protrusions 118 to bend and deflect when struck by the urine.
In order to effectively mount the anti-splash body 104 to the back wall 114, the anti-splash body 104 includes at least one fastener 126 sized and shaped to orient the anti-splash body 104 in the vertical direction parallel to a vertical direction of the back wall 114.

The protrusions 118, 300 can be seen tapering downwardly in a direction toward the front surface 120 of the anti-splash body 104 and the base 106 to further facilitate the water and/or urine flow. Said another way, the protrusions 118, 300 are wider at the location of the base than at the top. Such configuration causes the protrusions 118, 300 to break up the urine, while simultaneously allowing the urine to strike the front surface 120 and travel in the downward direction toward the drain when the urinal anti-splash device 100 is disposed in the vertical orientation. The tapering configuration also decreases the complexity associated with the manufacturing process of the device 100 because the protrusions 118, 300 may be relatively simply removed from the molding during the manufacturing process due to the lack of edges. In another embodiments, either the protrusions 118 or the protrusions 300 may include the tapering configuration. In other embodiments, the protrusions 118, 300 may be of a uniform width and devoid of the tapering configuration.
In one embodiment, the urinal anti-splash device 100 may include a fragrance embedded within the material of the urinal anti-splash device 100 during the manufacturing process, e.g., during the extrusion or molding phase of the manufacturing process. In another embodiment, the fragrance may be added to the material using a film process. The fragrance may be a volatile substance, such as a fragrant oil, an odor neutralizer, or the like. Such advantageous embodiments eliminate the need for the use of a room deodorizer or urinal cake that may be inconvenient and costly to consistently replace.
With reference now to
The thermochromic dye provides the user with the urinal anti-splash device 100 that changes color due to a change in temperature, e.g., that which occurs when urine strikes the thermochromic dye on the urinal anti-splash device 100. Advantageously, the thermochromic dye is not only aesthetically appealing, but also allows a viewer, such as maintenance personnel, to observe rinse coverage and the flow of water in order to efficiently and effectively clean the anti-splash device 100. As an added advantage, such configuration also allows businesses to advertise an insignia 602, e.g., a business name and/or logo, which becomes visible when the anti-splash device 100 changes color during use.
To effectuate the flow of a stream of urine along the urine flow path from the base 106 in a direction toward the urinal drain,
With reference now to the process flow chart of
In said process, the method begins as step 800 and immediately proceeds to step 802 of providing a urinal anti-splash device, such as the urinal anti-splash device 100 described above. More specifically, in one embodiment, the urinal anti-splash device 100 includes the anti-splash body 104 coupled to the base 106. As discussed above, the anti-splash body 104 may also include the first plurality of protrusions 118 extending outwardly from the front surface 120 of the anti-splash body 104 and the second plurality of protrusions 300 extending outwardly from the base 106. The second plurality of protrusions 300 are configured to extend in the direction substantially perpendicular from the first portion 108 of the anti-splash body 104.
In step 804, the process continues with mounting the anti-splash body 104 within a back wall of a urinal. In one embodiment, such mounting may be performed using suctions cups coupled to at least one fastener disposed on the urinal anti-splash device 100. In other embodiments, another type of fastener, e.g., adhesive, tape, hooks, etc., may be used to mount the anti-splash body 104 within the urinal.
Next, the process continues to the step of 806 of placing the base 106 over a urinal screen. Advantageously, in one embodiment, the process includes removably coupling, i.e., separating, the base 106 from the anti-splash body 104 such that the components may be independently positioned within the urinal. Such advantageous embodiment provides the urinal anti-splash device 100 that is not only conducive for placement within different size and shape urinals, but also may cover a portion of the surface area of the urinal, to prevent urine from splashing onto a user. The portion of the surface area of the urinal covered by the anti-splash device 100 may depend on the overall size of the urinal and the relative dimensions of the urinal anti-splash device 100.
In another embodiment, the process may include bending the urinal anti-splash device 100 at a location of a perforated coupling region disposed between the first portion 108 of the anti-splash body 104 and the base 106, as discussed above. The perforated coupling region is configured to translate the base 106 from a first position parallel to the anti-splash body 104 to a second position including the base 106 being in the direction substantially perpendicular from the first portion 108 of the anti-splash body 104. In such configuration the base 106 may remain coupled to the anti-splash body 104, or alternatively, may be detached from the anti-splash body 104. The process then terminates at step 808.
A urinal anti-splash device has been disclosed that not only includes an anti-splash body and a base that may be separated from each other to cover a back wall and a urinal screen to prevent urine from splashing onto a user of the urinal, but also provides an front surface conducive for allowing the urine and/or water to flow in a downward direction toward the urinal drain.
