DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

[0033] The following description is about embodiments of the present invention; however it is not intended to limit the scope of the present invention.

[0034] With reference to FIG. 1 for the front view of the structure improvement of the digital perpetual calendar clock in accordance with the present invention, the digital perpetual calendar clock includes an outer housing 1 covering the clock. When the user looks the clock window, the first digit rotational roller 2, the carrying shaft member 4 and the second digit rotational roller 3 are orderly disposed at the same shaft from left to right. The page sheet 20 is disposed on the first digit rotational roller 2 for displaying the digit and the page sheet 30 is disposed on the second digit rotational roller 3 for displaying the digit. The blocking element is disposed on the top of the clock window of the outer housing 1 by a predetermined angle and used to prevent the page sheet 20 and the page sheet 30 from being turned down too soon due to gravity, during the rotation of the rollers 2, 3, when they are tilted by an angle. The driving device 5 is disposed on the outer housing 1; the driving device 5 pushes the slot-type wheel on the second digit rotational roller 3 via the rotation of the circular pin wheel, which can intermittently drive the second digit rotational roller 3.

[0035] With reference to FIG. 2 for the structure diagram in the first viewing angle of the rollers and the shaft member of the structure improvement of the digital perpetual calendar clock in accordance with the present invention, at the left side is the first digit rotational roller 2, which includes 12 movable page sheets 20. As shown in FIG. 2, one side of the first digit rotational roller 2 is provided with a ring and the inner edge of the ring is provided with a plurality of converse teeth 24; besides, there are 2 carrying protrusion blocks 28 on the ring; the carrying protrusion blocks 28 can respectively trigger the micro switch (not shown in the drawings) on or inside the outer housing 1 when the first digit rotational roller 2 makes a half circle in order to generate a carrying signal. In addition, at the right side is the second digit rotational roller 3, which includes 10 movable page sheets 30; besides, the inner edge of the recess of the inner side thereof is provided with a protrusion block 32; in the embodiment, the protrusion block 32 is arranged according to the distance between 2 teeth.

[0036] Moreover, the carrying shaft member 4 is provided with a rotational teeth member 40 and the shaft core of the rotational teeth member 40 is disposed inside the carrying shaft member 4. One side, close to the first digit rotational roller 2, of the rotational teeth member 40 is provided with 8 protrusion teeth and the other side, close to the second digit rotational roller 3, thereof is provided with 4 protrusion teeth. The outer edge of the carrying shaft member 4 is provided with a cushion thereon and extending therefrom; the surfaces of the both sides of the cushion may be smooth. The cushion 42 is provided with a hole at the corresponding position so as to contain the rotational teeth member 40, and the 8 protrusion teeth and the 4 protrusion teeth of the rotational teeth member 40 are on the both sides of the cushion 42 respectively.

[0037] More specifically, when the polygonal rotational shaft penetrates through the first digital rotational roller 2, the carrying shaft member 4 and the second digit rotational roller 3 to combine these elements by the same shaft, one end of the carrying shaft member is embedded into one side of the first digit rotational roller 2 and the other end thereof is embedded into one side of the second digit rotational roller 3. In addition, the carrying shaft member 4 is fixed by the polygonal rotational shaft, but the first digit rotational roller 2 and the second digit rotational roller 3 can rotate. When the second digit rotational roller 3 rotates, the protrusion block 32 can contact the 4 protrusion teeth of the rotational teeth member 40 of the carrying shaft member 4 in order to drive the rotational teeth member 40 to rotate; in this way, the mutual link of the rotational teeth member 40 can be achieved by the parallel arrangement of the 4 protrusion teeth and the 8 protrusion teeth.

[0038] With reference to FIG. 3 for the structure diagram in the second viewing angle of the rollers and the shaft member of the structure improvement of the digital perpetual calendar clock in accordance with the present invention, at the left side is the second digit rotational roller 3 and there are 12 movable page sheets 30 disposed thereon. Besides, this side of the second digit rotational roller 3 is provided with a slot-type wheel 34 with arc recesses on the peripheral thereof. The slot-type wheel 34 includes a plurality of long recesses and a plurality of seminar recesses on the peripheral thereof. On the other hand, at the right side is the first digit rotational roller 2; similarly, there are 12 movable page sheets disposed on the first digit rotational roller 2 and the inner side thereof is provided with a circular recess which the carrying shaft member 4 is embedded into in the combination status; further, the edge of the inner side of the circular recess is provided with 24 protrusion teeth 22. When the first digit rotational roller 2, the carrying shaft member 4 and the second digit rotational roller 3 are combined at the same shaft, one end of the carrying shaft is embedded into the first digit rotational roller 2, such that the rotational teeth member 40 on the carrying shaft member 3 are engaged with the 24 protrusion teeth 22. In addition, when the rotational teeth member 40 on the carrying shaft member 4 rotates, the 24 protrusion teeth 22 engaged with the rotational teeth member 40 drives the first digit rotational roller 2. Further, the cushion 42 on the carrying shaft member 4 isolates the first digit rotational roller 2 and the second digit rotational roller 3, such that when the first digit rotational roller 2 and the second digit rotational roller 3 rotate, only the rotational teeth member 40 can transmit power but no frictional force generates; on the contrary, if the carrying shaft member 4 does not include the cushion 42, the first digit rotational roller 2 and the second digit rotational roller 3 will be influenced by the frictional force generating therebetween.

[0039] With reference to FIG. 4 for the first schematic view of the operation status of the structure improvement of the digital perpetual calendar clock in accordance with the present invention, FIG. 4 shows the view angle from the outer side of the second digit rotational roller 3, along the rotational shaft, to the first digit rotational roller 2. During the operation of the digital perpetual calendar clock, the driving device 5 is driven by the signals to intermittently rotate a circular pin wheel 50 extending therefrom. Then, the circular pin wheel 50 can press against the slot-type wheel 34 on the outer side of the second digit rotational roller 3; in this way, the slot-type wheel 34 can drive the second digit rotational roller 3 to rotate counterclockwise toward the rotational shaft in stepping manner. During the process of the rotation, each page sheet 30 is turned down with the change of the angle, and the page sheet 30 turned down will connect to the next page sheet 30 blocked by the blocking element 6 in order to show a plane with digit.

[0040] With reference to FIG. 5 for the second schematic view of the operation status of the structure improvement of the digital perpetual calendar clock in accordance with the present invention, FIG. 5 shows the view angle from the inner side of the second digit rotational roller 3, along the rotational shaft, to the first digit rotational roller 2. When the second digit rotational roller 3 rotates during the operation of the digital perpetual calendar clock, the protrusion block 32, disposed on the inner edge of the recess where the carrying shaft member 4 is embedded, simultaneously rotates. After rotating for a predetermined angle, the protrusion block 32 contacts the rotational teeth member 40 on the carrying shaft member 4, such that the rotation of the second digit rotational roller 3 can drive the rotational teeth member 40 on the carrying shaft member 4 to rotate along the shaft thereof.

[0041] With reference to FIG. 6 for the third schematic view of the operation status of the structure improvement of the digital perpetual calendar clock in accordance with the present invention, FIG. 6 shows the view angle from the inner space of the carrying shaft member 4 to the first digit rotational roller 2. The 24 protrusion teeth 22, disposed on the inner edge of the recess where the carry shaft member 4 is embedded, is engaged with the rotational teeth member 40 at the inner side of the first digit rotational roller 2; thus, when the rotational teeth member 40 fixed on the carrying shaft member 4 rotates along the shaft thereof, the 24 protrusion teeth 22 can transmit power to drive the first digit rotational roller 2 to rotate. During the process of the rotation, each page sheet 20 is turned down with the change of the angle, and the page sheet 20 turned down will connect to the next page sheet 20 blocked by the blocking element 6 in order to show a plane with digit, such that the clock of the present invention can carry the ones place to the tens place.

[0042] With reference to FIG. 7 for the fourth schematic view of the operation status of the structure improvement of the digital perpetual calendar clock in accordance with the present invention, FIG. 7 shows the view angle from the first digit rotational roller 2 to the second digit rotational roller 3; this view angle is contrary to the view angles of FIG. 4, FIG. 5 and FIG. 6; thus, FIG. 7 shows that the first digit rotational roller 2 rotates clockwise along the rotational shaft thereof. During the operation of the digital perpetual calendar clock, the limiting element 26, substantially being S-shaped, and the roller are disposed at the same shaft and fixed by the rotational shaft thereof. The limiting element 26 is embedded into the ring on one side of the first digit rotational roller 2 and the two ends, with horn shape, of the limiting element 26 are engaged with the converse teeth 24; the effect of the above structure is to limit the engaging angle between the converse teeth 24 and the limiting element 26 when the first digit rotational roller 2 rotates, such that the first digit rotational roller 2 will not rotate in the reverse direction.

[0043] According to the above embodiments, the structure improvement of the digital perpetual calendar clock in accordance with the present invention provides a flip clock with simple structure, which can reduce the cost incurred by the quantity of the page sheets. Further, with the core for clocking and the operation in stepping manner, the power consumption of the clock can be decreased, which can satisfy the requirement of long-term operation needed by perpetual calendar clock. Accordingly, the digital perpetual calendar clock provided by the present invention definitely has utility and novelty.

[0044] While the preferred embodiments of the invention have been set forth for the purpose of disclosure, modifications of the disclosed embodiments of the invention as well as other embodiments thereof may occur to those skilled in the art. Accordingly, the appended claims are intended to cover all embodiments which do not depart from the spirit and scope of the invention.
