The present invention is essentially related to a kind of cover installation or lid assembly for a toilet bowl or bidet.
The prior art includes the U.S. Pat. No. 1,342,505. The '505 patent is related to a toilet cover, which is coupled to the bidet or toilet with a hinge, so that the cover is opened by pivoting movement. In the '505 patent, the top surface of the cover faces the user serving as a back rest. The cover can be opened manually by lifting the handle. The handle is arranged in such a way so as to ensure that the top surface of the cover faces the user at all times when opened. When the body weight of the user is removed from the seat, the cover will fall to the closed position. U.S. Pat. No. 1,398,556 describes a kind of toilet cover which is opened by pressing a press bar. The body weight of the user on the press bar will force the cover to open. When the body weight of the user is removed from the press bar, the cover will fall to the closed position. The '556 patent discloses a toilet cover where the bottom surface of the cover faces the user, and another embodiment, wherein the top surface of the cover faces the user.
U.S. Pat. No. 2,219,044 is related to the toilet cover which is automatically operated by pressing a bar or pushing a button. The electromotor drives the cover to the opened position and enables the top surface of the cover to face the user. The lifting rod and the controlling bar are both pivotally connected to the cover and the toilet body. The '044 patent describes that the cover is fully automatically opened or closed. The United States Patent Application Publication No. 2006/0005309 is related to a kind of toilet cover which is manually operated through a handle, manually operated through a pedal or automatically operated through a motor. When the cover is opened, the bottom surface of the cover faces the user. The application discloses that a dual system can be an option.
Other prior art includes: International Patent Application Publication No. WO/2008/029388 which is related to the toilet cover that is automatically operated by an electric drive. A clutch system can optionally cut off the driving mechanism, so as to allow the cover to be manually operated in case at the absence of the rotation of electric motor. When the cover is opened, the bottom surface of the cover faces the user. Japanese patent application No. 2005-95502 describes a kind of toilet cover which can be opened and closed automatically. The cover includes two independent parts which are hinged together. When the cover rises, the front part of the cover bends downwards so as to ensure the front top surface of the cover faces the user.
What is needed is a toilet cover installation that allows a user to more easily open or close the cover automatically or manually, to a variety of positions, while allowing manual operation of the cover without damaging the driving device.
One embodiment of the present invention is related to an improved cover installation. The improved cover installation includes a base, a cover, and a connecting module which is used to connect the cover to the base. The cover installation further includes a plurality of connecting components, each of which is provided with coupling points to the cover and the base so as to allow rotational operations of the cover. One of the connecting components thereof implements pivoting movement with a pivot component, and while another connecting component moves in a pathway in sliding manner. In an exemplary embodiment, when the cover is in the opened position, the top surface of the cover can face the user or turn its back to the user.
Pursuant to another aspect or embodiment, the driving device is connected to at least one connecting component. The driving mechanism drives the connecting component to rotate about an axis so as to open or close the cover. For example, the user can activate said driving mechanism so as to automatically open or close the toilet cover. The sliding of the connecting component in the pathway can be selectively restricted, which prevents or allows the cover to revolve around the pivotal point of another connecting component. For example, in the automatic operation of the cover, the connecting component can be restricted within the pathway, allowing the cover to revolve around the pivotal point of another connecting component and to enable the top surface of the cover to face the user when the cover is in the opened position. Alternatively, during manual operation of the cover, the sliding of the connecting component may not be restricted in the pathway, preventing the cover from revolving around the pivotal point of a connecting component and causing the bottom surface of the cover to face the user when the cover is in the opened position.
In another aspect or embodiment of the present invention, the locking module can retain part of one of the connecting components in the pathway so as to facilitate the automatic operation of the cover. The connecting component can break away from the locking module to provide for manual operation of the cover without destroying the driving device of the cover. For example, the connecting component can be released from the locking module with some manual force, thereby allowing the cover to be opened or closed without enabling the driving device, so as to prevent the driving device from wearing or damage.
At least one aim of the embodiment of the present invention is to provide a cover installation which includes a base, a cover with a first surface and a opposite second surface. The cover installation further includes a connecting module having a first connecting component and a second connecting component. The connecting module is used to connect the base to the cover. The first connecting component is connected to the base by a first pivot component, and the first connecting component is connected to the cover by a second pivot component. The second connecting component is connected to the base by a third pivot component, and the second connecting component is connected to the cover by a fourth pivot component. The cover installation further can further include the sliding pathway described herein.
In one embodiment of the present invention, the sliding pathway is an integral part of the cover, and one of the second and the fourth pivot components is slidably set within the pathway. In another embodiment of the present invention, the sliding pathway is an integral part of the base, and one of the first and the third pivot components is slidably set within the pathway. In another embodiment of the present invention, said sliding pathway is an integral part of at least one of the first and the second connecting components. At least one of said connecting components includes at least two slidable coupling parts. In another embodiment of the present invention, the pivot component is a hinge.
An aspect of the present invention further includes at least one grip component coupled with the cover. Another aspect of the present invention further includes a locking module. Part of the first connecting component in the pathway can be restricted in releasable manner such that the first connecting component can not normally slide in the pathway (e.g., under automated force). One more aspect of the present invention further includes a driving device which is connected to at least one of the first and the second connecting components.
In another aspect of the present invention, the first connecting component is a kind of rod. In one more aspect of the present invention, the second connecting component is a kind of rod. In another aspect of the present invention, the pathway is a kind of groove.
Another aspect of the present invention further includes a pathway provided with a first end and a second end. In a closed position, the cover may extend forward from the mounting surface of the base and substantially parallel with the mounting surface of the base. The first surface of the cover faces away from the base. The cover may be moved to first and second opened positions. In the first and second opened positions, the cover may be set to be substantially vertical to the mounting surface of the base. In the closed position of the cover, the part belonging to the first connecting component, located in the pathway, is close to the first end of the pathway. In the first opened position of the cover, the part belonging to the first connecting component, located in the pathway, is close to the first end of the pathway and the first surface of the cover faces toward the bowl. In the second opened position of the cover, the part belonging to the first connecting component, located in the pathway, is close to the second end of the pathway and the second surface of the cover faces forward and toward the bowl.
While not shown, in varying embodiments, the cover 40 can be a cover with an opening, such as the toilet seat of the toilet bowl. The cover 40 can be made from any standard industrial materials such as, but not limited to, plastics, ceramics or metals. As illustrated in
The base 60 can be used to attach the cover installation 20 or the cover 120 to the equipment or the container, such as the toilet bowl or the bidet (
The second pivot component 68 connects the second base 90 of the second connecting component 84 to the base 60 by a pivotal connection. The third pivot component 70 of the cover 40 connects the second cover part 92 of the second connecting component 84 to the cover 40 by a pivotal connection.
In varying embodiments, each of the first pivot component 64, the second pivot component 68 and the third pivot component 70 is either a part of the cover 40 or a part of the base 60. The pathway 46 is either a part of the cover 40, or a part of the base 60 or a part of the connecting module 80. “A part” of the structure as mentioned above is defined as either integrally molded with the structure or as an annex of the structure. For example, as for the first pivot component 64, the second pivot component 68, the third pivot component 70, and the pathway 46, each of them can be either integrally molded with the cover 40 or the base 60, or can be an independent component annexed to the cover 40 or the base 60. For example, as for the first pivot component 64, the second pivot component 68 and the third pivot component 70, each of them can be an independent hinge which is annexed or installed to the cover 40 or the base 60. For example, pathway 46 can be a pathway which is formed in the independent component annexed to the cover 40 or the base 60. Or, for example, pathway 46 can be an integral part of the first connecting component 82 or the second connecting component 84. Alternatively, the pathway 46 can couple with another part of either the first connecting component 82 or the second connecting component 84. For example, both of the first connecting component 82 and the second connecting component 84 can be connecting components for retractable coupling.
The driving device 30 can be connected to at least one of the first pivot component 64, the second pivot component 68 and the third pivot component 70. For example, the driving device 30 can be connected only to the first pivot component 64, or can be connected only to the second pivot component 68, or can be connected to both the first pivot component 64 and the second pivot component 68 at the same time. Or, for example, the driving device 30 can be connected only to the third pivot component 70 or only to the pathway 46, or can be connected to the third pivot component 70 and the pathway 46 at the same time. The driving device 30 can thereby exert rotary force on only one of the first connecting component 82 and the connecting component 84, or can exert rotary force on both of the first connecting component 82 and the connecting component 84 at the same time. According to varying exemplary embodiments, a plurality of the driving devices 30 can be connected to a combination of the first pivot component 64, the second pivot component 68, the third pivot component 70 and the pathway 46.
Another embodiment of a cover installation 220 is illustrated from
Another embodiment of a cover installation 320 is illustrated in
Referring again to
Optionally, the operation of the cover 40 can be automated through the cover installation 120 (e.g., see
In order to automatically close the cover 40, the driving device 30 is activated after receiving a second signal, so as to make the first connecting component 82 and the second connecting component 84 revolve opposite to the direction in which they were opened. The cover 40 revolves opposite to the direction in which it was opened. The cover 40 returns to its original closed position, and at such position, the first surface 42 faces the space 28 which is located at the outside of the covered equipment, such as the space 28 located above the toilet bowl 25.
The cover 40 can also be manually lifted and lowered. In order to manually open the cover 40, the user touches part of the cover 40 and exerts force on the cover 40. Such force extends outward along the equipment. For example, the user grips the forepart of the cover 40 and lifts the cover 40 upward along the direction deviating away from the toilet bowl 25. The first connecting component 82 revolves around the axis of the first pivot component 64 and the second connecting component 84 revolves around the axis of the second pivot component 68. The first cover part 88's pivot component 66 slides towards the second position 53 until the first cover part 88's pivot component 66 is stopped by the second stop component 49. The cover 40 stops at a position basically fixed relative to the axis of the third pivot component 70. In the fully opened position, the second surface 44 of the cover 40 faces the space 28 outside of the opening of said equipment; for example, it faces the user of the toilet bowl 25. For example, during the service process of the toilet bowl 25, any splashes or directionless objects caused by the user will all fall on the second surface 44 so that the first surface 42 will be kept relatively clean. The user can also grasp the grip component 52 located at the rear part of the cover 40, and lift it upwards along the direction away from the toilet bowl 25 so as to make the cover 40 revolve around the connecting module 80, so that the cover 40 and its first surface 42 faces the user of the toilet bowl 25, the same as what was described previously about how the cover 40 automatically opens.
In order to manually close the cover 40, the user can manipulate part of the cover 40. For example, the user can hold the part considered as the front part of the cover 40, and pull it downwards toward the toilet bowl 25. The first cover part 88's pivot component 66 slides towards the first position 51 within the pathway 46 until the first cover part 88's pivot component 66 is stopped by the first stop component 47. The user can either lead the cover 40 back to the closed position, or release the cover 40 after the cover part 40 is partially closed so as to make the cover fall back to the closed position by gravity. The user can also hold the part considered as the rear part of the cover 40 and then push or pull it downwards toward the toilet bowl 25, so as to make the cover 40 revolve around the connecting module 80 (e.g., in the same fashion as that described previously regarding how the cover 40 can automatically close).
The cover installations 20 and 120 can optionally include the locking component 50. When the cover 40 is opened to the first opened position, the coupling component 55 can resiliently constrain the first cover 88's pivot component 66, so as to prevent it sliding toward the second position 53. The cover 40 revolves around the axis of the third pivot component 70 so as to make the first surface 42 face to the space 28 when the cover 40 is in the first opened position. In order to open the cover 40 to the second opened position, the coupling component 55 stops at a certain position so that the first cover 88 is constrained from sliding toward the second position 53. With force, the coupling component 55 can break away from the pathway 46 so as to allow the first cover 88's pivot component 66 to slide. The coupling component 55 can be somewhat flexible, so that the force from the first cover 88 can lead to deformation of the coupling component 55. With sufficient deformation, the first cover 88's pivot component 66 can slide through the coupling component 55 and towards the second position 53. In alternative embodiments, the coupling component 55 can be magnetic. In the process of manual operation, the force originally exerted on the cover 40 by the user can overcomes the resilient constraint force which is exerted on the first cover part 88 by the connecting component 55, so as to force the first cover part 88's pivot component 66 to break away from the connecting component 55 and to slide in the pathway 46. In the process of automatic operation, the force that is exerted by the driving device 30 and transferred to the first cover 88 is not exerted in the direction in which the first cover 88 is made to break away from the coupling component 55, and the strength of said force is not enough to cause the first cover 88 or the first cover 88's pivot component 66 to break away from the coupling component 55.
In the embodiment, wherein the pathway 46 is an integral part of the cover 40, the pathway 46 is set to be on the surface of or within the cover 40. The size of the locking component 50 may be restricted in such an embodiment. Locking component 50 may be configured to provide enough constraint force so as to prevent the sliding movement of the first cover 88 in the pathway 46 in the process of automatic operation. However, if the cover 40 and the pathway 46 are structured in such a way that the center of gravity of the cover 40 lies at the front of the pathway 46 when the cover 40 is in the closed position, then the use of the locking component 50 may not be necessary.
After the cover 40 is manually opened, the cover 40 can also be automatically closed as previously described. Or, after the cover 40 is automatically opened, the cover 40 can also be manually closed as previously described.
In an exemplary embodiment, the cover installation 20 includes a base 60, a first surface 42, a second surface 44, a pathway 46, a third pivot component 70, a cover 40 of the locking component 50, a first connecting component 82 and a second connecting component 84. A first base 86 of the first connecting component 82 is connected to the base 60 by the first pivot component 64. A first cover 88 (or the first cover's pivot component 66) of the first connecting component 82 is slidably coupled with the pathway 46. The first cover 88 (or the first cover's pivot component 66) of the first connecting component 82 is restricted by the locking component 50 in releasable manner. A second connecting component 84 has a second base 90 and is connected to the base 60 by the second pivot component 68, and the second cover 92 of the second connecting component 84 is pivotally connected to the third pivot component 70. A driving device 30 is optionally connected to at least one of the first connecting component 82 and the second connecting component 84.
In some embodiments, the first connecting component 82 is restricted by a locking component 50 in releasable manner. The driving device 30 is connected to the first connecting component 82. The first connecting component 82 can transmit the force from the driving device 30 so as to open and close the cover 40. When cover 40 is in the opened position the first surface 42 of the cover 40 faces the space 28. Such space 28 is above the area of the cover 40 when the cover 40 is in the closed position.
In another alternative embodiment of the present invention, the first connecting component 82 is restricted by the locking component 50 in releasable manner and the driving device 30 is connected to the second connecting component 84. The second connecting component 84 can transmit the force from the driving device 30 so as to open and close the cover 40. When the cover 40 is in the opened position, the first surface 42 of the cover 40 faces the space 28, which is above the area of the cover 40 when the cover 40 is in the closed position.
