2. Description of the Related Art
Applicant believes that one of the closest references corresponds to U.S. Patent Application Publication No. 20150164284 A1, published on Jun. 18, 2015 to Gary Sprague for a Sliding Shower Door Assembly. However, it differs from the present invention because Sprague teaches a fully frameless sliding shower door assembly. The assembly dispenses with the need for vertical framing members by using a panel of sufficient strength to be fully self-supporting. The need for an upper horizontal header member is eliminated by using a unique upper guide assembly wherein the guide is fixed to the movable shower door and configured to slide about a top edge of the stationary shower door. The need for a lower horizontal rail member is eliminated by the use of a unique, self-centering roller assembly that is attachable to the door panel without the need for a rail member. The roller assembly features matching inverted and non-inverted generally U-shaped profiles on the roller and track, respectively. The shower door assembly further features inboard and outboard roller finger guards, as well as a track leveling feature, which improves ease of installation.
Applicant believes that another reference corresponds to U.S. Patent Application Publication No. 20110072613 A1, published on Mar. 31, 2011 to James Hays for Spring Biased Roller for a Shower Door or the Like. However, it differs from the present invention because Hays teaches a roller for slidably mounting a panel such as a shower door to a rail or to a similar structure. The roller comprises a first cylindrical portion including a rolling surface for engaging the rail and a second cylindrical portion fixedly securable to the shower door panel. The second portion is concentrically mounted to the first portion and is rotatable relative thereto. A resilient member such as a tension spring connects the first portion to the second portion and stores a potential energy when a user moves the shower door in one direction and automatically urges the shower door to move in the opposite direction when released by the user.
Applicant believes that another reference corresponds to U.S. Patent Application Publication No. 20110005140 A1, published on Jan. 13, 2011 to Michael John Guidos et al. for Articulating Roller Arm Assembly.

The header further comprises at least first, second, third, and fourth roller assemblies that travel upon the channel. The first and second brackets receive the first and second ends respectively. The first and second brackets mount onto lateral walls to define a shower enclosure. A base assembly comprises third and fourth ends. First and second base brackets mount upon the third and fourth ends respectively. The base assembly mounts onto a mounting surface for the shower enclosure. The first and second brackets support a weight of shower doors of the shower enclosure without side jambs while the shower doors bypass one another.
The first, second, third, and fourth roller assemblies each comprise a frame securing a roller and a bushing. A pair of bushings secures each shower door. The frame further comprises a pin. Each of the first and second brackets comprises an exterior wall, an interior wall, a bottom wall, and a sidewall. Each sidewall comprises at least one hole to receive fastening means to mount onto the lateral walls of the shower enclosure. The sidewall may also comprise an adhesive element to mount onto the laterals walls of the shower enclosure. The exterior wall and the interior wall are parallel to each other. The sidewall is perpendicular to the exterior wall, interior wall, and bottom wall. The exterior wall, interior wall, and bottom wall extend a predetermined distance from the sidewall. The base assembly comprises at least first and second holes to receive fastening means to mount onto the mounting surface for the shower enclosure. The first and second base brackets comprise a base and an exterior face. The base comprises an adhesive element to mount onto the mounting surface for the shower enclosure. The base assembly comprises a guide element assembly. The guide element assembly comprises a guide frame. The guide frame comprises at least one guide. The shower door travels between at least two of the guides.
