FIELD OF THE INVENTION
[0001] The present invention relates to a toilet seat with an automatic turning cover, in
particular to an electric toilet seat that can be lifted and controlled electrically,
and whose surface can be turned towards the front while the toilet seat is being lifted.
BACKGROUND OF THE INVENTION
[0002] A conventional manual lifting toilet seat coupled to a toilet stool includes a toilet
seat cover and a toilet seat. The toilet seat cover and the toilet seat are regularly
covered onto the toilet stool, and the toiletseat is lifted up manually by hands when
the toilet stool is used. Particularly for male urinations, the toilet seat cover
is also lifted up to avoid spilling urine on the surface of the toilet seat cover.
However, for convenience, male users generally do not lift up the toilet seat cover,
and urine may be accumulated at the toilet seat cover and an internal side of the
lifted toilet seat. Even if the toilet seat cover is lifted, urine may be spilled
from a hollow portion of the toilet seat cover into the internal side of the toilet
seat. If the next user needs to sit on the toilet seat cover, the rear side of the
cloth of this user may touch the internal side of the toilet seat easily, which is
really disgusting. Although toilet seats with an electrically lifted cover are available
in the market, yet the toilet seats of this sort can lift the toilet seat only, and
the internal side of the toilet seat is still facing towards the front. Therefore,
it is unable to overcome the drawback of the cloth being in contact with the internal
side of the toilet seat having accumulated urine when a user is sitting on a toilet
seat cover. The sanitary problem still exists.
[0003] It is an important subject of the present invention to find a way of developing a
toilet seat with an automatic turning cover, such that users no longer have to lift
a toilet seat and a toilet seat cover by hands, and when the toilet seat is lifted,
the surface of the toilet seat will change its direction towards the front to avoid
the users' cloth from touching the internal side of the toilet seat.
SUMMARY OF THE INVENTION
[0004] In view of the aforementioned shortcomings of the conventional manual and electric
toilet seat, the inventor of the present invention based on years of experience in
the related industry to conduct extensive researches and experiments, and finally
developed a toilet seat with an automatic turning cover in hope of achieving the sanitary
effect.
[0005] Therefore, it is a primary objective of the present invention to provide a toilet
seat with an automatic turning cover, such that the surface of the toilet seat is
changed to face towards the front by means of a design of an electric toilet seat
and a turning structure when the toilet seat is lifted by an electric control, so
as to achieve the effects of providing a sanitary appearance, preventing the users'
cloth from touching the internal side of the toilet seat, providing an easy way of
using a toilet stool and keeping the toilet stool clean and sanitary.
[0006] To achieve the foregoing objective, the present invention provides a toilet seat
with an automatic turning cover, comprising: a start device, having a first rotating
portion and a second rotating portion disposed on a base respectively, and a motor
for driving and rotating the first rotating portion and the second rotating portion;
a toilet seat cover, with a rear end coupled with the second rotating portion of the
start device; a toilet seat, having a pivotal base disposed at an internal side of
the toilet seat, and the pivotal base having an upper pivoting portion and a belt
fixing portion; an elevating arm, with a rear end coupled with the first rotating
portion of the start device, and a lower pivoting portion disposed at the middle of
the elevating arm; a turning arm, having a long rod with a groove disposed at the
middle of the long rod, and a lower end of the long rod being rotably coupled to the
lower pivoting portion of the elevating arm, and an upper end of the long rod being
rotably coupled to an upper pivoting portion of the pivotal base on an internal side
of the toilet seat, an elastic element coupled with the upper end for pushing the
toilet seat, an upper axle installed transversally in the groove and proximate to
the upper end, and a lower axle is installed transversally and proximate to the lower
end; and a belt, with a lower end fixed at the bottom of the toilet seat cover, an
upper end passed from the bottom of the lower axle of the turning arm into the groove,
through the lower axle and the upper axle, and then from the top of the upper axle
and out of the groove, such that the upper end is coupled to the belt fixing portion
of the pivotal base on an internal side of the toilet seat to constitute the toilet
seat with an automatic turning cover.
[0007] The aforementioned design of a toilet seat with an automatic turning cover has at
least three modes of lifting a toilet seat. Firstly, a user can use the start device
to drive the elevating arm and the turning arm to lift the toilet seat independently
through an operation of a control box while the belt is pulled to change the direction
of the surface of the toilet seat to face towards the front, so as to achieve the
effect of keeping the toilet stool sanitary easily. Secondly, the start device can
be controlled and driven to lift the toilet seat cover and the toilet seat synchronously
when male users urinate, so as to prevent urine from being spilled onto the toilet
seat cover and maintain a clean and sanitary toilet stool. Thirdly, the toilet seat
or the toilet seat cover can be lifted manually during a power failure.

[0025] The belt 6 as shown in Figs. 1 to 3 is a flexible strip, whose lower end is passed
through the elevating arm 4 and the toilet seat cover 2 and fixed to the bottom of
the toilet seat cover 2 (as shown in Figs. 2 and 4), and whose upper end is passed
from the bottom of the lower axle 54 of the turning arm 5 into the groove 51, and
through the lower axle 54 and the upper axle 53, and then through the top of the upper
axle 53 and out from the groove 51, such that the upper end of the belt 6 is coupled
to the belt fixing portion 33 of the pivotal base 31 at the internal side of the toilet
seat 3.
[0026] In Figs. 1 to 3, the pivotal base 31 of the toilet seat 3 in accordance with the
preferred embodiment includes coupled to the two protruding bases 311 on the internal
side of the toilet seat 3, and the upper pivoting portion 32 and the belt fixing portion
33 are disposed transversally at transversal rods between the two protruding bases
311 respectively, and one of the transversal rods is passed through an upper end of
the turning arm 5, and another transversal rod is coupled to an upper end of the belt

61 can be an elliptical ring for latching to the belt fixing portion 33 in the shape
of the transversal rod.
[0027] With the design of a toilet seat with an automatic turning cover of the present invention
as shown in Fig.5, the toilet seat cover 2 and the toilet seat 3 are maintained covered
regularly, such that if a user needs to use the toilet stool, the user can lift the
toilet seat electrically by operating a control box or a sensor or by hands.
[0028] In the first type of the electric operating mode, a user performs the lifting operation
through the control box or sensor as shown in Figs. 2 and 6, so that the first rotating
portion 12 of the start device 1 is rotated, while the elevating arm 4 is being driven
to turn backward, and the elevating arm 4 is supporting the turning arm 5 synchronously,
and the toilet seat 3 pivotally coupled to the upper end of the turning arm 5 can
be lifted independently. In the meantime, the lower axle 54 of the turning arm 5 is
turned backward, and thus the lower axle 54 pulls the belt 6 gradually tighter, and
the upper end elliptical latch ring 61 is latched to the belt fixing portion 33 gradually
tighter. Until the toilet seat 3 is lifted to a specific height and a sufficient turning
space is reserved at the front end, the belt 6 and the latch ring 61 can drag the
belt fixing portion 33 downward until the toilet seat 3 is turned downward. In Figs.
7 and 8, if the elevating arm 4 and the turning arm 5 rise to fixed positions, the
belt 6 will pull the toilet seat 3 tightly, so that the surface of the toilet seat
3 will turn and change its direction towards the front of the toilet seat cover 2
to show the clean appearance of the toilet seat, and prevent a user's cloth from touching
the internal side of toilet seat 3 to achieve a sanitary effect easily when the user
uses the toilet stool. On the other hand, if the user controls the toilet seat 3 to
move downward to cover toilet seat cover 2 as shown in Figs. 1 and 5, the first rotating
portion 12 of the start device 1 will drive the elevating arm 4 and the turning arm
5 to turn forward, while the lower axle 54 of the turning arm 5 is turned forward
to release the belt 6, such that the upper end of the belt 6 is released from tightly
pulling the toilet seat 3, and then the elastic element 52 at the upper end of the
turning arm 5 props the toilet seat 3, so that the toilet seat 3 changes the direction
to be covered onto toilet seat cover 2.
[0029] In a second electric operating mode of the present invention, the user performs the
lifting operation through the control box or sensor as shown in Figs. 9 and 10, so
that the first rotating portion 12 and the second rotating portion 13 of the start
device 1 synchronously drive the elevating arm 4 and the toilet seat cover 2, wherein
the elevating arm 4 can also lift turning arm 5, such that the toilet seat 3 coupled
to the upper end of the turning arm 5 can be lifted. However, the toilet seat cover
2 is also lifted upward synchronously, so that a fixing point of the lower end of
the belt 6 being fixed to the bottom of the toilet seat cover 2 rises synchronously,
and the lower axle 54 of the turning arm 5 cannot pull the belt 6 tightly, and the
toilet seat 3 will not change its direction. The toilet seat 3 and the toilet seat
cover 2 stacked with one another are lifted together, so that a male user needs not
to lift the toilet seat 3 and the toilet seat cover 2 before taking a urination, and
the toilet seat cover 2 can be kept clean easily. On the other hand, both toilet seat
3 and toilet seat cover 2 can be turned downward simultaneously and covered onto the
toilet stool again.
[0030] In a third mode which is the manual operation of the present invention as shown in
Fig. 1, the user can lift the toilet seat 3 manually by hands during a power failure.
Now, the positioning steel ball 43 of the elevating arm 4 can be separated from the
positioning hole 55 of the turning arm 5, and only the turning arm 5 and the toilet
seat 3 are allowed to turn upward individually. The present invention provides a measure
for operating the toilet seat in a power failure situation.
[0031] In summation of the description above, the present invention achieves the effect
of using the toilet stool easily and sanitarily by changing the direction of the surface
of the toilet seat towards the front to avoid the user's cloth from touching the internal
surface of the toilet seat 3 when the user uses the design of the toilet seat and
the turning structure to electrically control and lift the toilet seat 3. Obviously,
the present invention complies with the patent application requirements and the products
manufactured in accordance with the present invention can meet the current market
requirements.
