Description

BACKGROUND

The present application relates generally to a hinge for a lid.

A lid may be attached to a toilet base using a hinge. The hinge facilitates rotation of the lid relative to the toilet base. Many hinges include two hinge members disposed on opposite sides of one edge of the lid. Each of these hinge members is attached to the lid and the toilet base and facilitates rotation of the lid about a single axis.

There are significant aesthetic and functional drawbacks associated with such a hinge. For example, the shape of the lid may be constrained to certain shapes having a relatively flat edge to which the hinge members are attached. Additionally, the lid may be separated from surrounding structures, such as a toilet tank, by a significant distance so as to facilitate rotation of the lid about the single axis without interfering with the surrounding structures. This distance causes an increase in the overall size of the toilet which consequentially causes the toilet to be more expensive and have a larger space claim.

DETAILED DESCRIPTION

Before turning to the figures, which illustrate the exemplary embodiments in detail, it should be understood that the present disclosure is not limited to the details or methodology set forth in the description or illustrated in the figures. It should also be understood that the terminology used herein is for the purpose of description only and should not be regarded as limiting.

I. Overview

Embodiments herein are generally directed to a toilet that includes a hinge assembly that facilitates opening and closing of a lid of the toilet such that a space claim of the toilet may be reduced. The hinge assembly described herein includes a mounting base coupler that is attached to a mounting base or body of the toilet and a lid coupler that is attached to the lid. The hinge assembly also includes at least one hinge member that is attached to both the mounting base coupler and the lid coupler and that facilitates rotation of the lid relative to the mounting base or body. The movement of the hinge assembly (i.e., forward and upwards) can bypass various obstructions and provide more lid layback (i.e., the amount that a distal end of a lid may rotate backwards towards a wall or toilet tank). For example, if a toilet is designed such that the rear surface of a toilet seat and lid are mounted very close to a toilet tank disposed behind the lid, the lid with a conventional hinge might not be able to open the entire way (i.e., greater than 90 degrees) before contacting the tank. Gravity may cause the lid to fall or close from such an open position. However, with the hinge assembly described herein, the rotation of the hinge assembly effectively causes the lid to move forward, allowing for more lid layback (i.e., the lid may open greater than 90 degrees) without contacting the tank. This additional lid layback allows the lid to remain open, such that it will not fall to a closed position due to gravity. In addition, the compact configuration of the hinge assembly may help with bypassing Americans with Disabilities Act compliant grab bars behind the toilet or any other obstruction.

II. The Toilet Having the Hinge Assembly

Referring to FIG. 1, a toilet 100 (e.g., commode, tankless toilet, etc.) is shown, according to an exemplary embodiment. The toilet 100 selectively receives waste (e.g., urine, feces, etc.) from a user (e.g., human, etc.) and selectively provides the waste to a sewage system (e.g., septic system, etc.). The toilet 100 may be installed in a user's home and/or in a commercial application, such as in a commercial building (e.g., office building, mall, etc.) or an industrial building.

The toilet 100 includes a base assembly 101 (e.g., support, etc.). The base assembly 101 is supported on a surface (e.g., floor, ground, tile floor, etc.). The base assembly 101 includes a body 102, a mounting base 103 (e.g., mounting assembly, etc.), and a lid assembly 104. The mounting base 103 is coupled to (e.g., attached to, affixed to, glued to, structurally integrated with, etc.) the body 102 along a body top surface 106 (e.g., face, deck, ledge, etc.) of the body 102.

The lid assembly 104 includes a lid 107 (e.g., cover, etc.). The lid 107 is coupled to the mounting base 103 via a hinge assembly 108 (e.g., hinge system, coupling system, single hinge, attachment system, etc.). The hinge assembly 108 is coupled to the mounting base 103. In some embodiments, the hinge assembly 108 is at least partially received within (e.g., contained in, positioned in, etc.) the mounting base 103. In various embodiments, the lid 107 is coupled to the mounting base 103 only via the hinge assembly 108 (e.g., the lid 107 is not coupled to the mounting base 103 using two hinge assemblies 108, the lid 107 is not coupled to the mounting base 103 using the hinge assembly 108 and another hinge, etc.).

The body 102 includes a bowl 109 (e.g., basin, etc.). The bowl 109 is contiguous with the body top surface 106. In operation, the bowl 109 receives waste from the user (e.g., human, etc.) and selectively provides the waste to a sewage system (e.g., septic system, etc.). The bowl 109 may also receive water from a water source (e.g., water supply, etc.) for facilitating removal of the waste from the bowl 109.

The hinge assembly 108 facilitates movement of the lid 107 relative to the mounting base 103. The hinge assembly 108 is operable between a first position (e.g., open position, use position, etc.) and a second position (e.g., closed position, resting position, storing position, etc.). When the hinge assembly 108 is in the first position, such as is shown in FIG. 1, FIG. 3, FIG. 4, and FIG. 6, the bowl 109 is exposed (e.g., the lid 107 does not cover the bowl 109 when the hinge assembly 108 is in the first position, etc.). As a result, waste may be deposited into the bowl 109. However, when the hinge assembly 108 is in the second position, such as is shown in FIG. 5 and FIG. 9, the bowl 109 is covered by the lid 107 (e.g., the lid 107 is configured to cover the bowl 109 when the hinge assembly 108 is in the second position, etc.). As a result, waste may not be deposited into the bowl 109. FIGS. 7 and 8 illustrate the hinge assembly 108 at intermediate positions between the first position and the second position. When the hinge assembly 108 is in the first position, the lid 107 is separated from the body top surface by an angle. In various embodiments, this angle is between 90 degrees and 120 degrees, inclusive. In some applications, this angle is equal to 90 degrees, 95 degrees, 100 degrees, 105 degrees, 110 degrees, 115 degrees, 120 degrees, or other similar values.

The mounting base 103 is disposed directly behind the bowl 109. In some embodiments, the mounting base 103 is contiguous with the bowl 109. The mounting base 103 includes a mounting base top surface 110 (e.g., face, deck, ledge, etc.). The mounting base top surface 110 may be disposed along a plane that is parallel to a plane upon which the body top surface 106 is disposed.

The mounting base top surface 110 is raised relative to the body top surface 106. A mounting base cavity (e.g., void, etc.) is formed between the mounting base top surface 110 and the body top surface 106. The mounting base top surface 110 includes a mounting base aperture 112 (e.g., hole, opening, etc.). The mounting base aperture 112 provides access into the mounting base cavity through the mounting base top surface 110. The mounting base aperture 112 may be centered on (e.g., aligned with a center point of, etc.) the bowl 109.

The hinge assembly 108 is coupled to the mounting base 103 underneath the mounting base top surface 110 and proximate the mounting base aperture 112. When the hinge assembly 108 is in the first position, a portion of the hinge assembly 108 protrudes through the mounting base aperture 112. However, when the hinge assembly 108 is in the second position, the hinge assembly 108 is concealed within the mounting base 103. In addition to covering the mounting base aperture 112, thereby mitigating ingress of debris into the mounting base aperture 112 and protecting the hinge assembly 108, the lid 107 may be disposed along a plane that is parallel to a plane upon which the mounting base top surface 110 is disposed.

The hinge assembly 108 includes a mounting base coupler 200 (e.g., body, etc.). In some embodiments, the mounting base coupler 200 is coupled to the mounting base 103. For example, the mounting base coupler 200 may be coupled to the mounting base top surface 110. In other embodiments, the mounting base coupler 200 is coupled to the body 102. For example, the mounting base coupler 200 may be coupled to the body top surface 106.

The mounting base coupler 200 includes at least one mounting base coupler outer sidewall 202. Each of the mounting base coupler outer sidewalls 202 extends a depth of the mounting base coupler 200. In some embodiments, the mounting base coupler outer sidewalls 202 are parallel (e.g., one mounting base coupler outer sidewall 202 is disposed along a plane that is parallel to a plane upon which the other mounting base coupler outer sidewall 202 is disposed, etc.). The mounting base coupler 200 also includes a mounting base coupler front wall 204. The mounting base coupler front wall 204 is coupled to each of the mounting base coupler outer sidewalls 202.

The mounting base coupler 200 also includes at least one outwardly extending protrusion 206 (e.g., projection, etc.). Each protrusion 206 extends laterally from one of the mounting base coupler outer sidewalls 202. In some embodiments, the mounting base coupler 200 includes two protrusions 206, one protrusion 206 extending laterally from one of the mounting base coupler outer sidewalls 202 and the other protrusion 206 extending laterally from the other of the mounting base coupler outer sidewalls 202. Each protrusion 206 has a substantially cylindrical shape and can be received within a bore of the mounting base 103, so as to mount the mounting base coupler 200 within the mounting base 103. In this way, the hinge assembly 108 may be rotatably coupled to the body 102.

The mounting base coupler 200 also includes a mounting base coupler first bore 208 (e.g., hole, opening, aperture, etc.). The mounting base coupler first bore 208 extends through the protrusion 206 and each of the mounting base coupler outer sidewalls 202. In some embodiments, the mounting base coupler first bore 208 is orthogonal to one of the mounting base coupler outer sidewalls 202. It is understood that the mounting base coupler first bore 208 includes a plurality of bore segments (e.g., a first segment within the protrusion 206, a second segment within one of the mounting base coupler outer sidewalls 202, a third segment within the other of the mounting base coupler outer sidewalls 202, etc.).

The mounting base coupler 200 also includes at least one mounting base coupler inner sidewall 210. Each of the mounting base coupler inner sidewalls 210 extends a portion of the depth of the mounting base coupler 200. Each of the mounting base coupler inner sidewalls 210 is separated from the mounting base coupler front wall 204. In some embodiments, the mounting base coupler inner sidewalls 210 are parallel (e.g., one mounting base coupler inner sidewall 210 is disposed along a plane that is parallel to a plane upon which the other mounting base coupler inner sidewall 210 is disposed, etc.). Each of the mounting base coupler inner sidewalls 210 may be parallel to one of the mounting base coupler outer sidewalls 202.

The mounting base coupler 200 also includes at least one mounting base coupler connecting wall 212. Each of the mounting base coupler connecting walls 212 extends between one of the mounting base coupler inner sidewalls 210 and one of the mounting base coupler outer sidewalls 202. In some embodiments, the mounting base coupler connecting walls 212 are each orthogonal to one of the mounting base coupler outer sidewalls 202 and/or one of the mounting base coupler inner sidewalls 210. The mounting base coupler connecting walls 212 may be aligned (e.g., disposed along the same plane, etc.).

The mounting base coupler 200 also includes a mounting base coupler second bore 214 (e.g., hole, opening, aperture, etc.). The mounting base coupler second bore 214 extends through the each of the mounting base coupler outer sidewalls 202 and each of the mounting base coupler inner sidewalls 210. In some embodiments, the mounting base coupler second bore 214 is orthogonal to one of the mounting base coupler outer sidewalls 202. In some embodiments, the mounting base coupler second bore 214 is parallel to the mounting base coupler first bore 208. It is understood that the mounting base coupler second bore 214 includes a plurality of bore segments (e.g., a first segment within one of the mounting base coupler outer sidewalls 202, a second segment within one of the mounting base coupler inner sidewalls 210, a third segment within the other of the mounting base coupler inner sidewalls 210, a fourth segment within the other of the mounting base coupler outer sidewalls 202, etc.).

The mounting base coupler first bore 208 is configured to receive a first hinge pin 216 (e.g., rod, dowel, etc.) extending therethrough. The first hinge pin 216 extends laterally and has a substantially cylindrical shape. The mounting base coupler first bore 208 is sized to receive the first hinge pin 216. Similarly, the mounting base coupler second bore 214 is configured to receive a second hinge pin 218 (e.g., rod, dowel, etc.) extending therethrough. The second hinge pin 218 extends laterally and has a substantially cylindrical shape. The mounting base coupler second bore 214 is sized to receive the second hinge pin 218. The first hinge pin 216 and second hinge pin 218 may have similar dimensions (e.g., diameters, lengths, etc.).

The hinge assembly 108 also includes a lid coupler 220. The lid coupler 220 is coupled to the lid 107. The lid coupler 220 includes at least one first flange 222 (e.g., projection, etc.) and at least one second flange 224 (e.g., projection, etc.). In some embodiments, each of the first flanges 222 and each of the second flanges 224 is disposed at a lateral end of the lid coupler 220. In various embodiments, a distance between the first flanges 222 is greater than a distance between the second flanges 224. However, in other embodiments, a distance between the first flanges 222 is less than a distance between the second flanges 224. In still other embodiments, a distance between the first flanges 222 is equal to (e.g., within 5% of, etc.) a distance between the second flanges 224.

Each of the first flanges 222 includes a lid coupler first bore 226 (e.g., hole, opening, aperture, etc.). The lid coupler first bore 226 is configured to receive a third hinge pin 228. The third hinge pin 228 is shown to extend laterally between the first flanges 222 and has a substantially cylindrical shape. In some embodiments, the lid coupler first bore 226 is parallel to the mounting base coupler first bore 208 and/or the mounting base coupler second bore 214.

Each of the second flanges 224 includes a lid coupler second bore 230 (e.g., hole, opening, aperture, etc.). The lid coupler second bore 230 is configured to receive a fourth hinge pin 232. The fourth hinge pin 232 is shown to extend laterally between the second flanges 224 and has a substantially cylindrical shape. In some embodiments, the lid coupler second bore 230 is parallel to the mounting base coupler first bore 208 and/or the mounting base coupler second bore 214.

The hinge assembly 108 also includes a first hinge member 234 and a second hinge member 236. As will be explained in more detail herein, the first hinge member 234 is coupled and the second hinge member 236 are each coupled to the mounting base coupler 200 and the lid coupler 220 and facilitate transition of the hinge assembly 108 between the first position and the second position. The first hinge member 234 is shown to be oriented substantially vertically (e.g., greater than or equal to 45° and less than or equal to 90°) in FIG. 3. The second hinge member 236 is shown to be oriented substantially vertically (e.g., greater than or equal to 45° and less than or equal to 90°) in FIG. 3.

The first hinge member 234 includes a first hinge member first bore 238 (e.g., hole, opening, aperture, etc.). The first hinge member first bore 238 extends through a first hinge member first end 240 (e.g., terminal end, etc.) of the first hinge member 234. The first hinge member first bore 238 is configured to receive the first hinge pin 216. The first hinge member first end 240 is configured to be received between the mounting base coupler outer sidewalls 202. Through the first hinge pin 216, the first hinge member 234 may be rotatably coupled to the mounting base coupler 200.

In some embodiments, the first hinge member first bore 238 is sized to facilitate rotation of the first hinge member 234 about the first hinge pin 216. In some embodiments, the mounting base coupler first bore 208 is sized to facilitate rotation of the first hinge pin 216 within the mounting base coupler first bore 208. In some embodiments, the first hinge member first bore 238 is sized to facilitate rotation of the first hinge member 234 about the first hinge pin 216 and the mounting base coupler first bore 208 is sized to facilitate rotation of the first hinge pin 216 within the mounting base coupler first bore 208.

The first hinge member 234 also includes a first hinge member second bore 242 (e.g., hole, opening, aperture, etc.). The first hinge member second bore 242 extends through a first hinge member second end 244 (e.g., terminal end, etc.) of the first hinge member 234. The first hinge member second bore 242 is configured to receive the third hinge pin 228. In some embodiments, the first hinge member first bore 238 is parallel to the first hinge member second bore 242. The first hinge member second end 244 is configured to be received between the first flanges 222. Through the third hinge pin 228, the first hinge member 234 may be rotatably coupled to the lid coupler 220.

In some embodiments, the first hinge member second bore 242 is sized to facilitate rotation of the first hinge member 234 about the third hinge pin 228. In some embodiments, the lid coupler first bore 226 is sized to facilitate rotation of the third hinge pin 228 within the lid coupler first bore 226. In some embodiments, the first hinge member second bore 242 is sized to facilitate rotation of the first hinge member 234 about the third hinge pin 228 and the lid coupler first bore 226 is sized to facilitate rotation of the third hinge pin 228 within the lid coupler first bore 226.

The second hinge member 236 includes a second hinge member first bore 246 (e.g., hole, opening, aperture, etc.). The second hinge member first bore 246 extends through a second hinge member first end 248 (e.g., terminal end, etc.) of the second hinge member 236. The second hinge member first bore 246 is configured to receive the second hinge pin 218. The second hinge member first end 248 is configured to be received between the mounting base coupler inner sidewalls 210. Through the second hinge pin 218, the second hinge member 236 may be rotatably coupled to the mounting base coupler 200.

In some embodiments, the second hinge member first bore 246 is sized to facilitate rotation of the second hinge member 236 about the second hinge pin 218. In some embodiments, the mounting base coupler second bore 214 is sized to facilitate rotation of the second hinge pin 218 within the mounting base coupler second bore 214. In some embodiments, the second hinge member first bore 246 is sized to facilitate rotation of the second hinge member 236 about the second hinge pin 218 and the mounting base coupler second bore 214 is sized to facilitate rotation of the second hinge pin 218 within the mounting base coupler second bore 214.

The second hinge member 236 also includes a second hinge member second bore 250 (e.g., hole, opening, aperture, etc.). The second hinge member second bore 250 extends through a second hinge member second end 252 (e.g., terminal end, etc.) of the second hinge member 236. The second hinge member second bore 250 is configured to receive the fourth hinge pin 232. In some embodiments, the second hinge member first bore 246 is parallel to the second hinge member second bore 250. The second hinge member second end 252 is configured to be received between the second flanges 224. Through the fourth hinge pin 232, the second hinge member 236 may be rotatably coupled to the lid coupler 220.

In some embodiments, the second hinge member second bore 250 is sized to facilitate rotation of the second hinge member 236 about the fourth hinge pin 232. In some embodiments, the lid coupler second bore 230 is sized to facilitate rotation of the fourth hinge pin 232 within the lid coupler second bore 230. In some embodiments, the first hinge member second bore 242 is sized to facilitate rotation of the first hinge member 234 about the third hinge pin 228 and the lid coupler second bore 230 is sized to facilitate rotation of the fourth hinge pin 232 within the lid coupler second bore 230.

When installed, the mounting base coupler 200 may receive the first hinge member 234 and the second hinge member 236. When the hinge assembly 108 is in the first position, the first hinge member second end 244 may be slightly behind (e.g., offset from, etc.) the second hinge member first end 248, such that the first hinge member 234 is oriented partially at an angle (e.g., an obtuse angle relative to the body top surface 106, etc.). Similarly, the second hinge member second end 252 is slightly behind the second hinge member first end 248, such that the second hinge member is oriented partially at an angle (e.g., an acute angle relative to the body top surface 106, etc.) when the hinge assembly 108 is in the first position.

When the hinge assembly 108 is in the first position, the third hinge pin 228 is substantially vertically above the fourth hinge pin 232. Additionally, the third hinge pin 228 and the fourth hinge pin 232 are disposed between the first hinge pin 216 and the second hinge pin 218 (e.g., the second hinge pin 218 is further from the mounting base coupler front wall 204 than the third hinge pin 228 or the fourth hinge pin 232) when the hinge assembly 108 is in the first position.

As the hinge assembly 108 transitions from the first position to the second position, the first hinge member 234 and second hinge member 236 are rotated backwards and downwards, such that they are substantially parallel behind the mounting base coupler front wall 204. During rotation of the hinge assembly 108 from the first position to the second position, the first hinge member 234 and the second hinge member 236 initially rotate in different rotational directions (e.g., the first hinge member 234 rotates counter clockwise and the second hinge member 236 rotates clockwise, etc.) and subsequently rotate in the same rotational direction (e.g., clockwise, etc.) as the hinge assembly 108 approaches the second position.

When the hinge assembly 108 is in the second position, the third hinge pin 228 is disposed at substantially the same height and in front of the fourth hinge pin 232. Furthermore, both the fourth hinge pin 232 and the third hinge pin 228 may be disposed behind (e.g., further from the mounting base coupler front wall 204, etc.) the first hinge pin 216 and the second hinge pin 218. In this way, the axis of rotation of the hinge assembly 108 is effectively shifted away from the mounting base coupler front wall 204 as the hinge assembly 108 transitions from the first position to the second position, thus enabling the hinge assembly 108 to be mounted closer to a rear wall 254 (e.g., surface, etc.) of the body 102. This enables the toilet 100 to have a smaller space claim than other similar toilets (e.g., toilets that have a similar capability for processing waste as the toilet 100, etc.).

When the hinge assembly 108 is in the first position, the second hinge member 236 contacts a mechanical stop to prevent further movement of the second hinge member 236 towards the mounting base coupler front wall 204. This mechanical stop may be structurally integrated within the mounting base coupler 200, such as within the mounting base coupler inner sidewall 210. Additionally, this mechanical stop may be the first hinge member 234 or may be structurally integrated within the first hinge member 234.

When the hinge assembly 108 is in the second position, the second hinge member 236 may contact a mechanical stop to prevent further movement of the second hinge member 236 towards the body top surface 106. This mechanical stop may be structurally integrated within the mounting base coupler 200, such as within the mounting base coupler inner sidewall 210. Additionally, this mechanical stop may be provided through contact between the lid 107 and the mounting base coupler 200, contact between the lid 107 and the mounting base 103, and/or contact between the lid 107 and the body top surface 106.

The third hinge pin 228 is disposed vertically above the fourth hinge pin 232 when the hinge assembly 108 is in the first position. Similarly, the third hinge pin 228 and the fourth hinge pin 232 may be disposed horizontally between the first hinge pin 216 and second hinge pin 218 when the hinge assembly 108 is in the first position.

FIG. 7 shows the hinge assembly 108 beginning to transition from the first position to the second position, in which the axis of rotation shifts backward, such that the third hinge pin 228 is disposed more forward than the fourth hinge pin 232. In addition, the lower end of the lid 107 begins to shift backward (e.g., away from the mounting base coupler front wall 204, etc.).

FIG. 8 shows the hinge assembly 108 transitioned closer to the second position than in FIG. 7 and with the axis of rotation shifted even further back, resulting in the lid 107 being closed even further, and the lower end of the lid 107 being further backward (e.g., away from the mounting base coupler front wall 204, etc.). As this occurs, the fourth hinge pin 232 and the third hinge pin 228 shift further backwards (e.g., away from the mounting base coupler front wall 204, etc.), such that both the third hinge pin 228 and the fourth hinge pin 232 are disposed further away from the mounting base coupler front wall 204 than both of the first hinge pin 216 or the second hinge pin 218.

FIG. 9 shows the hinge assembly 108 in the second position with the lid 107 oriented generally horizontally (e.g., the lid 107 is disposed along a plane that is generally parallel to a plane upon which the body top surface 106 is disposed, etc.). The third hinge pin 228 and the fourth hinge pin 232 are about horizontally aligned (e.g., disposed at about the same distance from the body top surface 106, etc.), with the fourth hinge pin 232 more being further from the mounting base coupler front wall 204 than the third hinge pin 228 or the fourth hinge pin 232. The first hinge member 234 and the second hinge member 236 are also stacked horizontally between the mounting base coupler 200 and the lid 107.

In some embodiments, a damper (e.g., shock absorber, etc.) is coupled to the mounting base coupler 200 and the lid coupler 220 and configured to facilitate a gradual transition of the hinge assembly 108 from the first position to the second position. For example, the damper may enable a user to remove the hinge assembly 108 from the first position and cause the hinge assembly 108 to automatically transition to the second position (e.g., due to gravity, etc.). In other embodiments, such a damper may be incorporated into the first hinge pin 216, the second hinge pin 218, the third hinge pin 228, and/or the fourth hinge pin 232 instead of being coupled to the mounting base coupler 200 and the lid coupler 220.

In various embodiments, the mounting base 103 is coupled to the body top surface 106 such that the mounting base 103 is disposed in confronting relation with the rear wall 254. In various embodiments, the toilet 100 and body 102 each have a generally oblong shape, while the bowl 109 has a substantially circular cross section. In various embodiments, the bowl 109 is disposed in a forward portion of the body 102.

The lid assembly 104 can also include a toilet seat that is configured to allow a user to sit on the toilet seat while using the toilet 100. The toilet seat can be rotatably coupled to the lid assembly 104 and/or the base assembly 101. In some embodiments, the toilet seat is rotatably coupled to the lid 107 and/or body 102 via the hinge assembly 108.

FIGS. 10-18 illustrate the toilet 100 according to various embodiments. As shown in FIG. 10, the distance between the mounting base top surface 110 and the body top surface 106 is less than the distance between the mounting base top surface 110 and the body top surface 106 in FIG. 1. Additionally, FIG. 10 illustrates the toilet 100 including a toilet seat 1000 (e.g., seat, etc.). The toilet seat 1000 is coupled to the mounting base 103 and is configured to rest upon the body top surface 106. In some embodiments, the toilet seat 1000 is rotatably coupled to the mounting base 103 separate from the lid assembly 104 (e.g., such that the toilet seat 1000 may be articulated independent of the lid assembly 104, etc.). In various embodiments, the toilet seat 1000 is not coupled to the hinge assembly 108.

As shown in FIG. 11, the toilet 100 does not include the protrusion 206. As a result, the mounting base coupler first bore 208 extends only through each of the mounting base coupler outer sidewalls 202.

As also shown in FIG. 11, the hinge assembly 108 includes a first damper 1100 (e.g., shock absorber, etc.) and a second damper 1102 (e.g., shock absorber, etc.). The first damper 1100 and the second damper 1102 are received within the mounting base coupler second bore 214 and are configured to receive the second hinge pin 218 (e.g., such that the second hinge pin 218 is received within the mounting base coupler second bore 214, etc.). The first damper 1100 and the second damper 1102 are each configured to facilitate a gradual transition of the hinge assembly 108 from the first position to the second position by resisting rotation of the second hinge pin 218 within the mounting base coupler second bore 214.

As also shown in FIG. 11, the hinge assembly 1108 may include sleeve bushings 1106 (e.g., sleeves, covers, etc.) disposed on ends of each of the first hinge pin 216, the second hinge pin 218, the third hinge pin 228, and/or the fourth hinge pin 232 so as to prevent wear of the first hinge pin 216, the second hinge pin 218, the third hinge pin 228, and/or the fourth hinge pin 232.

As also shown in FIG. 11, the lid coupler 220 may be divided into a first lid coupler portion 1108 and a second lid coupler portion 1110. By dividing the lid coupler 220 into the first lid coupler portion 1108 and the second lid coupler portion 1110, installation of the lid coupler 220 may be simplified. The first lid coupler portion 1108 may be symmetrical to the second lid coupler portion 1110.

As shown in FIG. 15, the hinge assembly 108 is in the first position, the second hinge member 236 contacts a mechanical stop 1500 (e.g., projection, protrusion, etc.) to prevent further movement of the second hinge member 236 towards the mounting base coupler front wall 204. The mechanical stop 1500 may be structurally integrated within the first hinge member 234.
