The present invention relates to a toilet installation part, especially to a fastener able to install and fix a toilet seat on a toilet base and the toilet seat with the fastener.
Generally, a toilet base is equipped with a toilet seat which is composed of an open seat and a lid, both pivotally connected to a base. The base is usually fastened by two bolts inserted through installation holes located at right and left sides on a top of a rear part of a toilet base and threaded by nuts correspondingly. Thus the toilet seat is installed and fixed on the toilet base.
However, a bottom of the rear part of the toilet base is usually close to a wall behind so that threading of the nut to the bolt in a narrow space is not easy for installers and special tools are required. Moreover, the bolt and the nut are maintained at the fastened state for a long period after installation, without being detached. Then the nut is difficult to be rotated and loosened from the bolt because it's not maintained in a clean condition or rusted. The following re-installation is also getting hard.
Furthermore, under certain conditions, the nut is loosened due to operation and use of the toilet seat and thus the normal use of the toilet seat is affected. The nut needs to be rotated and tightened again after a period of time.
In addition, the toilet base is often made of ceramic materials. A shrinkage rate of the ceramic materials is difficult to be controlled during formation process. Thus positions of the installation holes on the rear part of the toilet base produced each time often have greater differences, especially a distance between the two installation holes. This may cause the bolt unable to be inserted through the installation hole smoothly, difficulty in assembly, certain effects on assembly stability and quality, or loss in service life of assembled components.
In order to solve the above problems, an engagement apparatus is provided in Chinese Pat. No. CN111201380 B. The engagement apparatus has a plurality of embodiments. In one of the embodiments, an engagement apparatus in the form of a retaining pin can connect a seat and a lid to a toilet base. The engagement apparatus includes a pin inserted through a body section and an expandable section in turn and threaded to a second section as a nut. The body section is threaded with a first section and able to be threaded and fastened to a housing of a toilet seat. Thus the body section is like the base mentioned above. A lever is pivotally mounted to a top of the pin. By the lever being pulled and operated on the housing of the toilet seat, the pin is driven to move upward and downward axially. Thus the expandable section is squeezed by the first section and the second section axially to have elastic expansions and deformation. Thereby the second section, the expandable section, the first section, and a part of the pin can be abutted against and pressed tightly on the bottom of a hole of the toilet base while being inserted through the hole due to elastic expansions and deformation of the expandable section. Thus installers can easily pull and operate the lever from a top of the toilet base for mounting the seat and the lid to the toilet base. Similarly, by pulling and operating the lever from the top of the toilet base, the pin and the second section on the pin can also be driven to move downward axially. Thus the expandable section is elastically compressed or at least a part of the expandable section is returned to its original state. The seat and the lid are further detached and separated from the toilet base easily. The installer doesn't need to tighten or loosen the engagement apparatus in a narrow space under the toilet base. The problems occurred during fastening of the conventional toilet seat can be solved.
However, the above design still has certain shortcomings. For example, the engagement apparatus includes two pins used in combination with the lever, the body section, the first section, the expandable section, and the second section independent from one another. During installation of the seat and the lid, the installer needs to operate the lever separately, unable to install at one time.
Moreover, the above engagement apparatus has more components and the assembly is more complicated. Thus the installers may have faulty assembly.
Although the above body section can be directly fastened on the housing of the toilet seat, the two independent body sections on the left side and the right side need to be at the same level during threading and fastening and this causes trouble in assembly. The body section is unable to be adjusted horizontally by such assembly way. For example, the engagement apparatus can still be pressed tightly on the bottom of a hole of the toilet base by the expandable section when a distance between the left and the right holes of the toilet base is larger. A distance between the two independent body sections on the left side and the right side of the toilet base is unable to be adjusted slightly so that a distance between the top of the two pins is narrower while a distance between the bottom of the two pins is wider. Thereby the pin may be tilted. The expandable section of the engagement apparatus is unable to be pressed tightly on the bottom of the respective holes in the best condition once the pin is not in a vertical state. The assembly stability and fastening durability are further reduced. The pin may even have bending and deformation which further decrease the assembly stability and fastening durability.
The lever is not provided with drainage design, especially at the fastened state. With a smooth and flat upper surface, water is easy to accumulate on the upper surface of the lever and thus clean and sanitary use of the lever is affected.
The above first section is threaded to and positioned at the body section and able to be mounted into the hole of the toilet base from top to bottom. The diameter of the hole may have larger size error due to difficulty in control of shrinkage rate of the ceramic materials. In order to ensure that the first section can be mounted into the hole smoothly, the first section is a round tube with a fixed diameter which is usually designed to be obviously smaller than the diameter of the hole. Such design leads to a larger gap between the first section and an inner surface of the hole. Thereby a larger lateral movement and shaking may occur after installation of the seat and the lid and users may feel uncomfortable while in use.
Therefore, it is a primary object of the present invention to provide a fastener and a toilet seat with the same. By the fastener, the toilet seat can be firmly installed and fixed on a toilet base easily and fast. A detachment process of the toilet seat is also simple and quick.
In order to achieve the above object, a fastener according to the present invention includes a base, two upper holding boards, two stopping levers, two elastic expansion parts, two thread engaging members, and a stopping plate. The base consists of an upper surface, a lower surface, and a positioning slot which is arranged concavely on each of two sides of the lower surface. Each of the upper holding boards is provided with a positioning plate horizontally mounted and positioned in the positioning slot, a clamping projection extending and projecting from a lower surface of the positioning plate, and an insertion hole penetrating the positioning plate and the clamping projection. Each of the stopping levers is inserted through the insertion hole of the upper holding board and provided with a first end, a second end, and a threaded portion located at the second end. The elastic expansion parts are mounted to the stopping levers correspondingly and able to be squeezed axially to have elastic expansion. Each of the thread engaging members is connected to the threaded portion of the stopping lever by thread engagement so that the elastic expansion part is clamped and abutted against the clamping projection of the upper holding board. The stopping plate is able to be operated and rotated between a loose position and a tight position. The stopping plate is composed of two pivot slots corresponding to the positioning slots, a first pressing portion, and a second pressing portion. The first end of the stopping lever is pivotally connected to the pivot slot. When the stopping plate is rotated and positioned at the loose position, the first pressing portion is abutting against the upper surface of the base so that the stopping lever is moved for driving the thread engaging member to move downward axially. Thus the elastic expansion part is loosened and released. When the stopping plate is rotated and positioned at the tight position, the second pressing portion is abutting against the upper surface of the base so that the stopping lever is moved to drive the thread engaging member to move upward axially. Thus the elastic expansion part is squeezed and expanded.
The fastener further includes two rotary shafts. Each of two sides of the stopping plate is provided with a lateral insertion hole communicating with the pivot slot. The rotary shaft is inserted through the lateral insertion hole for pivotally connecting the first end of the stopping lever to the pivot slot.
The fastener further includes two sealing plugs each of which is used for sealing the lateral insertion hole.
A first radial distance is formed between the first pressing portion and an axis of the corresponding rotary shaft of the fastener. A second radial distance is formed between the second pressing portion and the axis of the corresponding rotary shaft of the fastener. The second radial distance is larger than the first radial distance.
A press surface is disposed on one side of the stopping plate opposite to a side of the stopping plate with the second pressing portion for allowing users to press and operate. Thus the stopping plate is rotated and moved from the loose position to the tight position.
The stopping plate includes a first side and a second side opposite to each other. The pivot slot is corresponding to the first side. A lip-shaped pull portion is projecting and extending from the second side so that users can pull and apply force to the pull portion for rotating the stopping plate from the tight position to the loose position.
An upper surface of the pull portion of the fastener is smoothly extending from the press surface.
The press surface and the upper surface of the pull portion of the fastener are tilted and combined to form a draining surface when the stopping plate is at the tight position.
The clamping projection of the upper holding board of the fastener is tapered from a junction between the clamping projection and the positioning plate toward an end of the clamping projection to form a conical cylinder.
The fastener further includes two anti-slip washers. Two installation slots are disposed on the lower surface of the base and located around the positioning slot for mounting and positioning the anti-slip washers correspondingly. A bottom of the anti-slip washer is provided with an anti-slipping surface which is a little bit projecting from the lower surface of the base. The anti-slip washer is further provided with an opening for allowing the clamping projection of the upper holding board to insert through.
An omnidirectional horizontal movement gap is formed between the positioning plate of the upper holding board and the positioning slot of the base of the fastener.
A sliding gap is formed between the stopping lever and the pivot slot of the stopping plate of the fastener for allowing fine adjustment and sliding of the stopping lever on the corresponding rotary shaft.
A fastener according to the present invention includes a base, two upper holding boards, two stopping levers, two elastic expansion parts, two thread engaging members, and two stopping plates. The base consists of an upper surface, a lower surface, and a positioning slot which is arranged concavely on each of two sides of the lower surface. Each of the upper holding boards is provided with a positioning plate horizontally mounted and positioned in the positioning slot, a clamping projection extending and projecting from a lower surface of the positioning plate, and an insertion hole penetrating the positioning plate and the clamping projection. Each of the stopping levers is inserted through the insertion hole of the upper holding board and composed of a first end, a second end, and a threaded portion located at the second end. The elastic expansion parts are mounted to the stopping levers correspondingly and able to be squeezed axially to have elastic expansion. Each of the thread engaging members is connected with the threaded portion of the stopping lever by thread engagement so that the elastic expansion part is clamped and abutted against the clamping projection of the upper holding board. Each of the stopping plates is able to be pulled and rotated between a loose position and a tight position and is composed of a pivot slot corresponding to the positioning slot, a first pressing portion, and a second pressing portion. The first end of the stopping lever is pivotally connected to the corresponding pivot slot. When one of the stopping plates is rotated and positioned at the loose position, the first pressing portion of the stopping plate is abutting against an upper surface of the base so that the corresponding stopping lever is moved to drive the corresponding thread engaging member to move downward axially. Thus the corresponding elastic expansion part is loosened and released. When one of the stopping plates is rotated and positioned at the tight position, the second pressing portion of the stopping plate is abutting against the upper surface of the base so that the corresponding stopping lever is moved to drive the corresponding thread engaging member to move upward axially. Thus the corresponding elastic expansion part is squeezed and expanded.
The fastener further includes two rotary shafts. At least one of two sides of the stopping plate is provided with a lateral insertion hole communicating with the pivot slot for allowing the rotary shaft to insert in. Thereby the first end of the stopping lever is pivotally connected to the pivot slot by the rotary shaft.
The fastener further includes two sealing plugs each of which is used for sealing the lateral insertion hole.
A first radial distance is formed between the first pressing portion and an axis of the corresponding rotary shaft of the fastener. A second radial distance is formed between the second pressing portion and the axis of the corresponding rotary shaft of the fastener. The second radial distance is larger than the first radial distance.
A press surface is disposed on one side of the stopping plate opposite to a side of the stopping plate with the second pressing portion for allowing users to press and operate. Thus the stopping plate is rotated and moved from the loose position to the tight position.
Each of the stopping plates is provided with a first side and a second side opposite to each other. The pivot slot is corresponding to the first side. A lip-shaped pull portion is projecting and extending from the second side so that users can pull and apply force to the pull portion for rotating the stopping plate from the tight position to the loose position.
An upper surface of the pull portion of the fastener is smoothly extending from the press surface.
The press surface and the upper surface of the pull portion of the fastener are tilted and combined to form a draining surface when the stopping plate is at the tight position.
The clamping projection of the upper holding board of the fastener is tapered from a junction between the clamping projection and the positioning plate toward an end of the clamping projection to form a conical cylinder.
The fastener further includes two anti-slip washers. Two installation slots are disposed on the lower surface of the base and located around the positioning slot for mounting and positioning the anti-slip washers correspondingly. A bottom of the anti-slip washer is provided with an anti-slipping surface which is a little bit projecting from the lower surface of the base. The anti-slip washer is further provided with an opening for allowing the clamping projection of the upper holding board to insert through.
An omnidirectional horizontal movement gap is formed between the positioning plate of the upper holding board and the positioning slot of the base of the fastener.
A sliding gap is formed between the stopping lever and the pivot slot of the stopping plate of the fastener for allowing fine adjustment and sliding of the stopping lever on the corresponding rotary shaft.
A toilet seat is provided. The toilet seat is installed on a toilet base and is composed of the fastener, an open seat, and a lid. An installation wall is arranged at a top of a rear part of the toilet base and provided with two installation holes. The lower surface of the base of the fastener can be attached to and pressing against an upper surface of the installation wall of the toilet base. The clamping projection of the upper holding board is moved downward to be mounted and positioned in the corresponding installation hole. When the stopping plate is at the tight position, at least a part of the elastic expansion parts is moved upward to be mounted and clamped in the corresponding installation hole for creating clamping and fastening effect. When the stopping plate is at the loose position, the elastic expansion part is moved downward or released from the corresponding installation hole. Thus at least a part of the elastic expansion part is returned to original state elastically for allowing the elastic expansion part to move upward and insert through the corresponding installation hole. A pivot joint seat is projecting from the upper surface of the base and located adjacent to the stopping plate for pivot connection and positioning of the open seat and the lid.
By the design of the single stopping plate in the first fastener, loosening or fastening of the two fastening members at the left side and the right side can be finished at the same time during one operation. Thus the assembly or dis assembly process can be simplified and detachment efficiency is increased.
With fewer components, the present fastener can be assembled easily and fast. Incorrect assembly by staff can also be avoided.
Compared with conventional threaded engagement structure, the design of the positioning plate of the upper holding boards horizontally mounted and positioned in the positioning slot of the base not only provides easier and faster assembly but also ensures the upper holding boards of the fastening members at the left side and the right side both at the same level, especially the clamping projection of the upper holding board which affects consistency of the following elastic expansion or compression of the respective elastic expansion parts.
The present invention not only provides a horizontal movement gap designed between the positioning plate of the upper holding board and the positioning slot of the base for allowing automatic fine adjustment of the positioning plate in the positioning slot but also provides a sliding gap formed between the first end of the stopping lever and the pivot slot of the stopping plate for allowing fine adjustment and sliding of the first end of the stopping lever on the corresponding rotary shaft. When there is a larger difference in the distance between the installation holes on the left side and the right side of the toilet base, the whole stopping lever together with the components thereof can keep at the vertical state by the horizontal movement gap combined with the sliding gap. Thus the respective fastening members can provide fastening effect in optimal condition. Therefore, the installation is more stable and the fastening is more durable. Bending deformation of the stopping lever caused by tilting can also be avoided. The service life and functions of the component are ensured.
The stopping plate is provided with the press surface conductive to drainage and the pull portion extending smoothly from the press surface to avoid water accumulated on the surface of the stopping plate. Thereby clean and sanitary use of the stopping plate are ensured, especially when users need to operate the stopping plate later.
The clamping projection of the upper holding board is tapered from a junction between the clamping projection and the positioning plate toward an end of the clamping projection to form a conical cylinder. Such design not only allows the clamping projection able to be mounted to the installation holes easily and quickly. Under installation and fastening condition, the design is also ensured that a gap between the clamping projection and the installation holes will not be too large, or the clamping projection is even locked and positioned in an inner wall of the installation holes no matter a diameter of the installation holes is getting larger or smaller due to shrinkage of ceramic materials after molding. Thereby the installed toilet seat will not have obvious lateral movement or shaking and a sense of discomfort derived during the use can be avoided effectively.
An anti-slip washer is arranged around the respective positioning slots of the lower surface of the base. The anti-slip washer is not only made from anti-slip material such as rubber material able to have larger friction force with respect to ceramic materials but also distributed around the respective fastening members and arranged evenly on the left and the right sides of the base for providing more even and larger contact area on the right and the left sides of the base. After completing installation of the above the above fastener, the anti-slip washer is pressed tightly on the right and the left sides of an upper surface of the installation wall evenly and firmly and further providing good anti-slip and fastening effect. The slip resistance between the toilet seat and the upper surface of the toilet base is further improved and strengthened. The lateral movement or sliding generated and a sense of discomfort derived in use can be avoided effectively.

Each of the stopping levers 30 is inserted through the through hole 131 of the base 10 and the insertion hole 23 of the upper holding board 20 and having a first end 31, a second end 32, and a threaded portion 33 located at the second end 32. In this embodiment, the threaded portion 33 is designed to be a segment with external threads.
The elastic expansion parts 40 are inserted by and mounted to the stopping levers 30 correspondingly and able to be squeezed axially to have elastic expansion.
The elastic expansion part 40 is designed to be a cylindrical tube. When an upper end and a lower end of the elastic expansion part 40 are squeezed axially, a middle part of the elastic expansion part 40 is gradually expanded radially to provide impaction and fastening required. It can be easily imagined that the shape is not limited to the cylindrical tube mentioned above, the shape can also be others such as a barrel bulging out in the middle. Basically, the shape of the elastic expansion part 40 meets structural requirements of the present invention as long as the middle part is bulging when the upper and the lower ends are squeezed.
The elastic expansion parts 40 can be made of elastic materials such as common rubber material.
Each of the thread engaging members 50 is connected to the threaded portion 33 of the stopping lever 30 by thread engagement so that the elastic expansion part 40 is clamped and abutted against the clamping projection 22 of the upper holding board 20. In this embodiment, the thread engaging member 50 is a nut in a cylindrical tubular form or other forms.

In this embodiment, the first pressing portion 62 and the second pressing portion 63 mentioned above can be designed to be about a flat surface and its advantage is in that: a more stable pressing effect is obtained while the first pressing portion 62 or the second pressing portion 63 is abutting against the upper surface 11 of the base 10. The design prevents the stopping plate 60 from loosening caused by unintended collision or shaking, especially uncontrollable self-loosening while the stopping plate 60 is rotating from the tight position to the loose position.
In this embodiment, the fastener 1 further includes two rotary shafts 70. Each of two sides of the stopping plate 60 is provided with a lateral insertion hole 611 communicating with the pivot slot 61 for allowing the rotary shaft 70 to insert in. Thus the first end 31 of the stopping lever 30 is pivotally connected to the pivot slot 61 by the rotary shaft 70. In this embodiment, an axial hole 311 is mounted to the first end 31 of the stopping lever 30 and inserted by and combined with the rotary shaft 70 to form a rotation axis around which the stopping plate 60 is rotated between the loose position and the tight position.
In this embodiment, the fastener 1 further includes two sealing plugs 71 each of which is used for sealing the lateral insertion hole 611 to prevent water or other impurities and objects from entering the lateral insertion hole 611. Thus smooth rotation and operation are ensured.
As shown in
It is learned that when the stopping plate 60 is operated and rotated from the loose position to the tight position, the stopping plate 60 is gradually changed from the state of the first pressing portion 62 abutting against the upper surface 11 of the base 10 to the state of the second pressing portion 63 abutting against the upper surface 11 of the base 10. On the contrary, when the stopping plate 60 is operated and rotated from the tight position to the loose position, the stopping plate 60 is gradually changed from the state of the second pressing portion 63 abutting against the upper surface 11 of the base 10 to the state of the first pressing portion 62 abutting against the upper surface 11 of the base 10. In order to ensure smooth switching and operation, a curved guiding surface 64 is designed to be located between the first pressing portion 62 and the second pressing portion 63.
The design with an eccentric cam can form structure similar to the above first pressing portion 62, the second pressing portion 63, and the curved guiding surface 64 and provide similar loosening and fastening effects. The difference between the common eccentric cam design and this embodiment is in that the about flat surface of the first pressing portion 62 and the second pressing portion 63 can prevent the stopping plate 60 from uncontrollable loosening compared with the common eccentric cam design.
In this embodiment, a press surface 65 is disposed on one side of the stopping plate 60 opposite to a side of the stopping plate 60 with the second pressing portion 63 for allowing users to press and operate. Thus the stopping plate 60 is rotated from the loose position to the tight position. As shown in figure, it is clear that the press surface 65 is about on an upper side when the stopping plate 60 is at the tight position, as shown in
In this embodiment, as shown in
In a preferred embodiment, an upper surface 672 of the pull portion 671 is smoothly extending from the press surface 65. When the stopping plate 60 is located at the tight position, the press surface 65 and the upper surface 672 of the pull portion 671 are tilted and combined to form a draining surface which keeps clean water flowing and draining automatically.
In a preferred embodiment, the clamping projection 22 of the upper holding board 20 is tapered from a junction between the clamping projection 22 and the positioning plate 21 toward an end of the clamping projection 22 to form a conical cylinder. By design of the conical cylinder, the clamping projection 22 of the upper holding board 20 can be guided into a hole smoothly such as a hole of a toilet base. A detailed description is provided in the following paragraphs.

The difference between the fastener 2 and the fastener 1 is in that: the fastener 2 of this embodiment is provided with two stopping plates 60a which can be imagined to be formed by cutting of a middle portion of the stopping plate 60 of the above embodiment. Each of the stopping plates 60a is provided with one of the pivot slots 61 and one of the lateral insertion holes 611 respectively used for mounting one of the rotary shafts 70 and one of the sealing plugs 711.
It is easily understood that the upper holding board 20, the stopping lever 30, the elastic expansion part 40, and the thread engaging member 50 of the above embodiment are combined to form a fastening member which is disposed on both the left side and the right side of the base 10 for ensuring fastening security and stability. In this embodiment, each of the stopping plates 60a can be installed independently or combined with the fastening member.
The design of the single stopping plate 60 in the first embodiment is good at that the two fastening members are moved synchronously for loosening or fastening by one operation. Yet the two fastening members in this embodiment need to be operated independently. However, the independent design also has other advantages. For example, the stopping plates 60a can be replaced separately.

Generally speaking, no matter the one-piece toilet or other types of toilets, the toilet base is provided with the installation wall 93 and the installation hole 931 on the installation wall 93, as shown in
In summary, the fastener 1, 2 and the toilet seat 3 have the following features and advantages.
By the design of the single stopping plate 60 in the first fastener 1 of the first embodiment, loosening or fastening of the two fastening members at the left side and the right side can be completed by one operation at the same time. Thus the assembly or disassembly process can be simplified and detachment efficiency is increased.
Moreover, with fewer components, the present fastener 1, 2 can be assembled easily and fast. Incorrect assembly by staff can also be avoided.
Furthermore, compared with conventional threaded engagement structure, the design of the positioning plate 21 of the upper holding boards 20 horizontally mounted and positioned in the positioning slot 13 of the base 10 not only provides easier and faster assembly but also ensures the upper holding boards 20 on the fastening members at the left side and the right side both at the same level, especially the clamping projection 22 of the upper holding board 20 which affects consistency of the following elastic expansion or compression of the respective elastic expansion parts 40.
In addition, the present invention not only provides the horizontal movement gap S1 designed between the positioning plate 21 of the upper holding board 20 and the positioning slot 13 of the base 1 for allowing automatic fine adjustment of the positioning plate 21 in the positioning slot 13 but also provides the sliding gap S2 formed between the first end 31 of the stopping lever 30 and the pivot slot 61 of the stopping plate 60, 60a for allowing fine adjustment and sliding of the first end 31 of the stopping lever 30 on the corresponding rotary shaft 70. When there is a larger difference in the distance between the installation holes 931 on the left side and the right side of the toilet base, the whole stopping lever 30 together with the components thereof can keep at the vertical state by the horizontal movement gap S1 in combination with the sliding gap S2. Thus it is ensured that the respective fastening members can provide fastening effect in optimal condition. Therefore, the installation is more stable and the fastening is more durable. Bending deformation of the stopping lever 30 caused by tilting can also be avoided. The service life and functions of the component are ensured.
Additionally, the stopping plate 60, 60a is provided with the press surface 65 conductive to drainage and the pull portion 671 extending smoothly from the press surface 65 to avoid water accumulated on the surface of the stopping plate 60, 60a. Thereby clean and sanitary use of the stopping plate 60, 60a is ensured, especially when users need to operate the stopping plate 60, 60a later.
The clamping projection 22 of the upper holding board 20 is tapered from the junction between the clamping projection 22 and the positioning plate 21 toward the end of the clamping projection 22 to form a conical cylinder. Such design allows the clamping projection 22 able to be mounted to the installation holes 931 easily and quickly. Under installation and fastened condition, the design also ensures that there is no large gap generated between the clamping projection 22 and the installation holes 931 and the clamping projection 22 is even locked and positioned in an inner wall of the installation holes 931 no matter the diameter of the installation holes 931 is getting larger or smaller due to shrinkage of ceramic materials after molding. Thereby the installed toilet seat 3 will not have obvious lateral movement or shaking while in use and a sense of discomfort derived can be avoided effectively.
An anti-slip washer 80 is arranged around the respective positioning slots 13 on the lower surface 12 of the base 10. The anti-slip washer 80 is not only made from anti-slip material such as rubber material able to have larger friction force with respect to ceramic materials but also distributed around the respective fastening members evenly for providing more even and larger contact area on the right and the left sides. After completing installation of the above the above fastener 1, 2, the anti-slip washer 80 is pressed tightly on the right and the left sides of the upper surface 932 of the installation wall 93 of the toilet base evenly and firmly and further providing good anti-slip and fastening effect. Thereby slip resistance between the toilet seat 3 and the upper surface 932 of the toilet base is further improved and strengthened. The deviation or sliding generated in use and discomfort derived can also be avoided effectively.
Additional advantages and modifications will readily occur to those skilled in the art. Therefore, the invention in its broader aspects is not limited to the specific details, and representative devices shown and described herein. Accordingly, various modifications may be made without departing from the spirit or scope of the general inventive concept as defined by the appended claims and their equivalent.
