Detailed Description of the Embodiments

[0048] In this first embodiment, this device is comprised of: a first screed ring 5, a second screed ring 10, and a slope guide 30. A screed ring is a rigid ring-shaped element with a predetermined shape which has a top edge which is commonly referred to as a screed edge 20. During the use of this device, a first screed ring 5 and a second screed ring 10, each having different desired radiuses and being placed on different horizontal planes, are located and placed on the shower floor mud 75. Such as depicted in FIG. 4 the first screed ring 5 has a smaller diameter than the second screed ring 10. The first screed ring 5 is also located on a lower altitude relative to the second screed ring 10. Also, the first screed ring 5 is located below the top of the drain at a desired distance H such as depicted in FIG. 3. Each screed ring and screed ring segment has a predetermined height and thickness.

[0049] The geometric centers of the screed rings are located on the same vertical axis Z, (FIG. 1,3,6), which passes through the geometric center of the shower drain 1. In other words, the drain 1, the first screed ring 5, the second screed ring 10 are placed concentrically when the device is installed correctly. The first screed ring 5 and second screed ring 10 are placed onto the shower floor mud 75 as depicted in FIG. 4. The screed edges of the two screed rings must be located on two different horizontal planes with the desired distances between them. The screed rings are implanted temporarily or permanently into the shower floor mud 75. One small screed ring and at least one big screed ring is required. Both the first screed ring 5 and the second screed ring 10, collectively referred to herein as screed elements, have a screed edge 20, which is shown in FIG. 2. The screed edge 20 is the top edge of those two elements and supports a screed tool 80, which is shown in FIG. 4. The screed tool 80 is a rigid structurally sound element which has a straight edge which is used for removing excess floor mud 75, which is above the screed elements.

[0050] It is anticipated that this device may be alternatively comprised of a first screed ring 5 and at least one segment 15 of a second screed ring. FIG. 6 depicts the device being used with only one segment 15 of the second screed ring. If more than one segment 15 is provided, the segments 15 of the second screed rings can be interconnected to form an incomplete screed ring or a complete circular screed ring. It is anticipated that one first screed ring 5 and at least one segment of the second screed ring 15 are required, which is shown in FIG. 6. The screed elements are comprised of a first screed ring 5, and at least one second screed ring 10 or at least one second screed ring segment 15.

[0051] Both the first screed ring 5 and the segment of the second screed ring 15 have a screed edge 20, which is shown in FIG. 2. The screed edge 20 is the top edge of those two elements and the screed edge 20 supports a screed tool 80 (FIG. 4). The orientation and location of the screed edges 20 determines the desired orientation of the screed tool 80 such as depicted in FIG. 4 and determines the desired uniform slope/shape of the shower floor mud 75. At least two screed edges 20, with each screed edge 20 provided on a screed ring and segment of a screed ring with different desired radiuses and located on different desired horizontal planes are required. The geometric centers of all screed elements 5,10,15 are located on the same vertical axis Z.

[0052] The segments 15 of the screed ring are a plurality of rigid ring-shaped portions of a screed ring that can be used as single segments or interconnected together to form a partial or complete screed ring. Different sized desired diameter screed rings can be formed and used in the installation of a shower floor mud surface 75. The segments of the screed ring 15 can either be attachable to each other or not attachable to each other such as depicted on FIG. 9. The device could be used with the following combinations of the elements: screed rings only; screed rings with one or more slope guides; one or more screed ring, segments; the first screed ring and one or more second screed ring segments, and one or more slope guides.

[0053] The slope guide 30, which is shown in FIGS. 1,3,5,6,7,8 is a rigid structurally sound element which holds together temporarily or permanently the first screed ring 5 and the second screed ring 10 and ensures the desired location and orientation of those screed rings in relation to each other, to a drain 1 and on the desired orientation in 3D space as depicted in FIG. 3. The purpose of the slope guide 30 is to ensure that the screed elements attached to it are implanted into the floor mud 75, so as to create the desired slope of the floor mud 75 after the screed tool 80 is used. The slope guide 30 holds the screed elements in a desired location and orientation in three-dimensional space after the device is installed. On the bottom surface of the slope guide 30 there are two ring grooves: a first ring groove 40 and a second ring groove 45 into which the screed elements will be placed. The first ring groove 40 holds the first screed ring 5. The second ring groove 45 holds the second screed ring 10 or second screed ring segment 15. The depth of the respective grooves is different so that the respective screed rings can be properly positioned when implanted into the shower floor mud 75. The depth of the first ring groove 40, which is shown in FIG. 3 and FIG. 5 has less depth than the second ring groove 45, as depicted in FIG. 3, to ensure the proper slope is achieved when the device is installed. The difference between the depths of two ring grooves is A (FIG. 3). The difference between radius C of the first screed ring 5 and radius D of the second screed ring 10 is B. The desired correlation between A and B ensures correct uniformed slope to the drain of the shower floor mud surface. The desired distance between the first ring groove 40 and the second ring groove 45 ensures desired distance B (FIG. 1,3,6), between two rings or ring and segment(s) of the rings, when those are installed into slope guide. If the screed Ring Grooves are round, the Geometric Centers of both ring grooves are located on the same vertical axis Z (FIGS. 1,6.8), when the device is installed correctly. Ring grooves can have a straight or other shape of design. In this case, the shape of the ring grooves should ensure that the geometric centers of all screed elements should be located on the same vertical axis Z.

[0054] The long side middle axis of the Slope Guide 30 also goes through the vertical axis Z and under 90 degree angle to it, when this device is installed correctly. Ring Grooves can be specially designed and not round. In this case, the long side middle axis of the Slope Guide 30 goes through the vertical axis Z and under 90 degree angle to it, when the device is installed correctly.

[0055] The dimension F, which is shown in FIG. 3, is the desired distance between the plane of the horizontal top surface 35 of the slope guide 30 and the plane of the bottom 50 of the first ring groove 40. Dimension E which is shown in FIG. 3, is the desired distance between the plane of the horizontal top surface 35 of the slope guide 30 and the plane of the bottom 50 of the second ring groove 45. The plane or surface of the bottom of the first ring groove and plane of the bottom of the second ring groove are both parallel to the plane of the horizontal top surface of the slope guide 30. When the device is installed properly, with the plane of the top of the slope guide 30 horizontal, dimension F and E ensures that the desired location and orientation of both inserted elements of the device are in 3D space.

[0056] When the device is installed properly, the desired dimension H, which is shown in FIG. 3, shows the position of the device in relation to the top surface of the shower drain 1. Dimension H is the distance between top of the shower drain 1 and the bottom 50 of the first screed ring's groove 40 and the top of the shower floor mud 75 surface around the drain 1. Distance H gives the space for the thickness of ceramic tile and the thickness of a setting material, commonly known as thin-set, which is installed on top of the floor mud 75. The desired dimension H ensures that top surface of the ceramic tile will be flat and even with the top surface of the shower drain 1, after the ceramic tile is installed. The top surface of the shower drain 1 is referred to as a datum, which determines the position of both screed rings in the vertical direction.

[0057] The plurality of holding screws 55, which is shown in FIG. 3 and FIG. 5 is used to ensure that the screed elements do not move inside the grooves during the installation of the device.

[0058] In an alternative embodiment, the slope guide 30 may be modified such as depicted in FIG. 7 to incorporate at least one leveling adjusters 60 and a recessed portion of the bottom surface of the slope guide 65. It is anticipated that there may not be a milled-out portion 65 in this alternative embodiment. The plurality of leveling adjusters 60 permit the craftsman to appropriately level the slope guide 30 to ensure a proper orientation of the slope guide 30. When the plurality of level adjusters 60 is utilized, the device initially stands on the shower pan base. When the plurality of level adjusters 60 are absent or removed, the device stands on the floor mud 75. The device can also be placed on top of the shower floor mud 75 with level adjusters 60. The milled-out portion 65 of the bottom surface of the slope guide 30 reduces pressure of the floor mud 75 onto the bottom of the slope guide 30 at a time of installation on top of the floor mud 75. The slope guide 30 also provides a flat top surface, which can support a level measuring tool in order to verify the horizontal orientation of the top surface of the slope guide 30.

[0059] The slope guide 30 may also incorporate a vertical pole 70 (FIG. 10) on the slope guide's top surface 35 in order to use an alternative level measuring tool, such as a post level or post level alike, to determine the horizontal orientation of the top surface of the slope guide 35. When the vertical pole 70 is oriented in vertical position in 3D space, the top surface of the slope guide 35 is horizontal.

[0060] It is also anticipated that the slope guide 30 can also be used as a screed tool 80.

[0061] This device is usable with at least two ring-shaped screed elements with different desired geometric radiuses and temporarily or permanently embedded to the shower floor mud 75 with the desired location and orientation.

[0062] The geometric centers of all ring-shaped elements are located on the vertical axis Z, which passes through the geometric center of a shower drain 1. The screed edge 20 of each screed element is located on its own horizontal plane with a desired distance between those two planes in a vertical direction and with the desired difference between the geometric radiuses of two elements.

[0063] The screed rings are embedded into the shower floor mud 75 for the purpose of creating support for the screed tool 80 (FIG. 4), which creates the desired surface of the shower floor mud 75 with the desired uniform slope to a shower drain 1 such as depicted in FIG. 4. The device is used with or without a slope guide 30. The slope guide 30 can be used with screed rings or with first ring 5 and segment of the second screed ring 15; the segments of the screed rings 5 can be interconnected to form a partial or complete circular screed ring, which is shown in FIG. 9. The segments of the second screed ring 15 or the complete screed ring 10 can be used with a slope guide 30 to achieve the desired uniform slope to the shower drain 1. The first screed ring 5 and the second screed ring 10 can be made from segments attached together or as one solid piece with two opposite ends connected together such as depicted in FIG. 9. Both rings can be made as a one solid piece which is a cut from tubing with desired diameter. The screed rings can also be molded.

[0064] There are four methods by which the device may be used. All four methods create a desired uniform slope to a drain 1 with a desired smooth surface of the shower floor mud 75.

[0065] In the first method, only screed rings of the device are used: the first screed ring 5 and the second screed ring 10. This method is used when the entire area of the shower floor could be done at the same time and a tradesman is able to install the screed rings correctly without using the slope guide 30 and with traditional tools available. The first method is to place mud 75 on the shower floor and then position the screed rings on top of it, where the first screed ring 5 (small ring) is at the center of the second screed ring 10 (big ring) and the shower drain 1 is at the center of the first screed ring 5. The screed edge 20 of the second screed ring 10 is desirably higher than the screed edge 20 of the first screed ring 5. The screed edge 20 of the first screed ring 5 is desirably below the top surface of the shower drain 1. The top edge/screed edge of the second screed ring 10 and first screed ring 5 are in two different horizontal planes, with a desired distance between those planes. After both rings are correctly installed and securely positioned inside the floor mud 75, a tradesman drops more mud 75 on top of the rings and around. At this point the mud should be pressed down/packed by a flat shape tool before the excess of the floor mud 75, which is above the screed rings, is removed/shaved off with a screed tool 80. The desired distance between the screed edges of the second screed ring 10 and first screed ring 5 in the radial direction, and the desired difference between the altitudes of the screed edges 20 of both screed rings determines the correct uniform slope of the floor mud 75 surface at any point of shower floor. When both rings are disposable, they can be left inside the floor mud 75. The reusable screed rings should be removed and the empty gaps of floor mud surface left from the removed screed rings should be filled with an extra portion of the floor mud 75 and the surface of the floor mud 75 should be finished/ironed with a flat shaped tool. Once the shower floor mud 75 is finished, the shower floor mud job is considered done.

[0066] In the second method, the following elements of the device are used: the first screed ring 5, the segment of the second screed ring 15, and the slope guide 30. This method should be used when, a mud job is performed section by section, or when the shower drain is close to a wall of a shower and a full screed ring cannot be used. After all elements are assembled together, a slope guide 30 and the floor mud 75 is placed on the shower floor. The device is placed on top of the floor mud 75 with the shower drain 1 located at the center of the first screed ring 5. Then, the slope guide 30, with all elements attached, is pressed into the floor mud 75 until the top surface of the slope guide 30 is horizontal and the screed edge 20 of the first screed ring 5 is located below the top of the drain 1 at the desired distance and level/horizontal. The second screed ring segment 15 should also be level/horizontal. The slope guide 30, thereby automatically generates the desired distance between the screed edges 20 of the first screed ring 5 and the segment of the second screed ring 15 in vertical and horizontal radial directions. Also, when the top surface 35 of the slope guide 30 is horizontal, the slope guide 30 ensures the correct horizontal position of both screed elements of the device. After the device is correctly assembled and the elements are securely positioned inside floor mud 75, the slope guide 30 is then unattached and removed.

[0067] The user then places more shower floor mud 75 on top of the designated area of the shower floor. The shower floor mud 75 should be packed down by a flat shape tool before the excess of the shower floor mud 75 is removed or shaved off with a screed tool 80. The first screed ring 5 and first segment of the second screed ring 15 are temporarily left inside the mud in a first section of the shower floor area. A second screed ring segment 15 of the second screed ring is attached to the slope guide 30. Then both of them are installed on top of the mud in the second section. For instance, in the opposite direction of the shower floor area, where the shower floor mud 75 was just installed.

[0068] If the drain 1 is close to the wall the second section will be located next to the first section, which is already made. In this case, a doubled screed ring segment 15 (half of the ring) can be used, if necessary.

[0069] The screed edge 20 of the first screed ring 5, which was already implanted into the shower floor mud 75, is then placed into the first screed rings groove 40 of the slope guide 30. After being correctly located, the slope guide 30 is pressed into the floor mud 75 until the top screed edge 20 of the first ring 5 touches the bottom of the related ring's groove 40 and until top surface 35 of the slope guide 30 is substantially horizontally level. The slope guide 30 automatically secures the desired location and orientation of the second segment 15 of the second screed ring. After the second segment 15 of the second screed ring is firmly secured into floor mud 75, the slope guide 30 is then unattached and removed. A tradesman or other user would then place more shower floor mud 75 on top of the second section of the working area of the shower floor area. Then the shower floor mud 75 should be pressed or packed down by a flat shaped tool before excess of the shower floor mud 75 is removed or shaved off with a screed tool 80. Then, two additional segments 15 of the second screed ring can be installed. When two segments of the second screed ring 15 are already implanted in two opposite sections of a shower floor with the help of a slope guide 30, the other two sections 15 of the second screed ring 10 can be installed without the slope guide 30 manually. Those two can be implanted into the shower floor mud 75 with bare hands and with the same shower floor mud 75 operational procedure. Before the excess of the floor mud 75 is shaved off by the screed tool 80, the top edges of the previously installed ring segments should be lined up in a horizontal plane with the top edges of the freshly installed (manually installed) ring segments 15, and connected or overlapped over each other.

[0070] After all four areas of the shower floor are done, the disposable elements can be left inside the shower floor mud 75. The reusable elements must be removed, and the empty gaps are filled with mud. The mud on the surface of the floor is then fixed, (ironed) by a flat shape tool. The shower floor mud job is now considered finished. The user may utilize level adjusters, when he uses the slope guide 30. Also, the user can use a vertical pole, in order to use the alternative way to verify the level of the top surface of the slope guide 35, when he installs the device.

[0071] With the third method, the following elements of the device are used: first screed ring 5, a second screed ring 10, and a slope guide 30. This method is used when the entire area of the shower floor could be done at the same time. This method is similar to the first method, where the slope guide 30 was not used. This method uses a slope guide 30 in order to make this method more effective and easier than the first one. The slope guide 30 automatically secures the correct location and orientation of first screed ring 5 and second screed ring 10, and therefore simplifies and speeds up the process and increases the level of precision. After all of the elements are assembled together and the shower floor mud 75 is placed on the floor, the device is placed on top of the shower floor mud 75 and the shower drain 1 is located at the center of a first screed ring 5. Then the slope guide 30, with all of the elements attached, is pressed into the shower floor mud 75 until top surface of the slope guide 35 and screed edge 20 of the first screed ring 5 and the second screed ring 10 are level/horizontal; the screed edge 20 of the first screed ring 5 is located below the top surface of the shower drain 2 at the desired distance. The slope guide 30 ensures the desired distance between the screed edges 20 of the first screed ring 5 and the second screed ring 10 in vertical and in horizontal radial directions. After the device with the elements are correctly installed and the elements are firmly implanted/secured into the shower floor mud 75, the slope guide 30 is then unattached and removed, only if the slope guide 30 is reusable. Then user/operator drops more shower floor mud 75 on top of the working area. Then the mud should be pressed down/packed by a flat shape tool before the excess of the floor mud is removed/shaved off with a screed tool 80. The disposable elements can be left inside the shower floor mud 75. When the reusable elements are removed, the empty gaps are filled with shower floor mud 75, and the surface of the floor mud is fixed/ironed by a flat shape tool. The shower floor mud job is now considered finished. The device created a smooth shower floor mud 75 surface with correct uniform slope to the shower drain 1 at any point of a shower floor area. The user may utilize level adjuster(s) 60 (FIG. 7), when using the slope guide 30. Lever adjuster(s) 60 can be used when the surface of the shower pan is fairly good, decently level and has no significant defects. With level adjusters 60 the operator can install the device on top of the shower pan first and then drop the shower floor mud 75 on the top and around. An alternative modification with more than one slope guides 30, at least one level adjuster 60 per each slope guide 30 can be used. Also, the user can use a pole, in order to use alternative way to verify level of the top surface of the slope guide 30, when he installs the device.

[0072] With the fourth method, more than three elements of the device are used: first screed ring 5, second screed ring 10, and more than one slope guides 30. This kind of device or element can be disposable or reusable. The device with more than one slope guides 30 would be preferably used when level adjusters 60 are present and used. At least one level adjuster 60 per each slope guide 30 can be used. The lever adjuster(s) 60 can be used when surface of the shower pan is fairly good, decently level and has no significant defects. With the level adjusters 60 the operator can install the device on top of the shower pan first and then drop the shower floor mud 75 on top of the device and around. This method is similar to the third method with the differences that, in this case, the device has more than one slope guide 30 and the device is installed on the shower pan first and then the shower floor mud 75 is dropped on top and around. The entire device can be made as a solid mold, made by other different way structure, or it can be easily assembled from more than one molded or made by other different way sections. In this case the device can be located in the shower pan and then the mud work is performed. Alternatively, for both reusable and disposable versions, the floor mud can be dropped first, and then the device can be placed on top of the shower floor mud 75.

[0073] In the following step, the device is placed in the bottom of the shower pan with the drain 1 located at the center of a first screed ring 5, then by rotating the level adjusters 60 in the required direction, the tradesman achieves the desired orientation in the 3D space of all the elements of the device. The top surface of all slope guides 35 should be level/horizontal. As long as the slope guides 35 are level, the screed edges 20 of both rings will be level/horizontal automatically. The screed edge 20 of the first screed ring 5 should be lower than the top surface of the drain 1. The slope guide 30 thereby automatically ensures the desired distance between the screed edges 20 of the first screed ring 5 and the screed edge 20 of the second screed ring 10 in vertical and horizontal radial directions. After the device is correctly installed the user/operator drops the shower floor mud 75 on top and around the device. After the first screed ring 5 and the second screed ring 10 are firmly secured inside the shower floor mud 75, the slope guides 30 can be unattached and removed, if the slope guides 30 are reusable. Then the user/operator drops more shower floor mud 75 on top of the working area. Then the shower floor mud 75 should be pressed down/packed by a flat shape tool before the excess of the shower floor mud 75 is removed/shaved off with a screed tool 80. The device creates a smooth shower floor mud 75 surface with the correct uniform slope to the shower drain at any point of the shower floor. If some elements of the device or the entire device is disposable, then those elements of the device or the entire device can be left inside the shower floor mud 75. The reusable elements are removed, and the empty gaps are filled with shower floor mud 75 and the surface of the floor mud is fixed/ironed by a flat shape tool. The shower floor mud job is considered finished. If the slope guides 30 are disposable, it should be modified in the way that top surface of the slope guide(s) 35 are located at the same altitude as the screed edges 20, or lower. When level adjusters 60 are in use, at least one level adjuster 60 is required for each slope guide 30.

[0074] This device may be further comprised of a screed tool 80. A screed is the term used to describe a rigid object with a straight edge that is drawn over freshly poured concrete/mud on top of specially designed rigid and stable support. The device described herein is a rigid buildup support for the screed and described in four separate embodiments. The shape of this support determines the shape of the shower floor mud 75 surface. The support is comprised of a plurality of screed elements. A screed element may be a first screed ring 5, a second screed ring 10, or a segment of a screed ring 15. A screed edge 20 is a top edge of each of the screed elements of the device that are in contact with a screed tool 80 while in use. When the screed tool 80 is moved on top of a screed edge 20 of the screed elements, it forms the desired uniformed slope and shape of the shower floor mud 75 surface by removing the excess of the mud, which is above those elements of the device. The mud 75 which is left below the screed edges 20 is formed with the desired and required shape. In some instances, the slope guide 30 can be used as a screed tool 80.

[0075] In all methods, with use of the Slope Guide 30, operator has an option not to remove Slope Guide(s) 30 before screeding process. Screed can be done in all shower floor area, where it's possible, then entire assembled device (Rings and Slope guides) can be removed from the shower floor mud 75, and then additional portion of the floor mud 75 can be filled up in empty/hollow spaces left by the device's elements.
