The following specification particularly describes the invention and the manner in which it is to be performed
BACKGROUND
Field of Invention
[001] Embodiments of the present invention generally relate to a protection equipment and particularly to an umbrella device.
Description of Related Art
[002] Natural resource elements are associated with day-to-day activities such as, sunlight, rainfall, and so forth which has both positive as well as negative impact on lives and property. Rainfall impacts negatively by destructing and/or damaging nursery bed herbs, and causing skin disorder in humans, fever and sickness, and alike. To overcome such problems, technology has made several advancements in domains which are beneficial for users in protection against the rainfall. One such accomplishment includes an umbrella.
[003] The umbrella is a popular device that has been used by users from a very long time to get protection from the rainfall. In a conventional approach, a hand-held umbrella has been used that is having a folding canopy supported by ribs and mounted on a pole to protect the users against the rainfall. However, in case of a sudden rainfall, sometimes the users will find themselves stuck in opening the umbrella due to some mechanical issue in the umbrella. To overcome such a problem, various other umbrella devices such as, a telescopic umbrella with an integral anchor, a beach umbrella having a telescopic shank, a tiltable umbrella, an adjustable umbrella, a rain catcher, and so forth have been developed. Though, such devices provide a stand that enables the users to alter a preferred length of the umbrella. However, such devices are having the stand which is lifted by using various mechanisms such as screw, nuts and sliding mechanisms. Such mechanism tends to be very complex which in turn increases a manufacturing cost of the device. Also, such devices are having a handle that is actuated with a rotation of a hand gripping portion, to open or close the umbrella that makes such devices manually operated devices.
[004] There is thus a need for an advanced and more-effective umbrella device that can administer the drawbacks faced by the conventional devices.
SUMMARY

The cylinder 132 may comprise a piston 138, a spring 140 and a piston rod 142 inside the inner wall 136 of the cylinder 132. The piston 138 may be in a circular shape that may slide freely inside the inner wall 136 of the cylinder 132 for locking and/or unlocking the middle hollow pipe 106b and the bottom hollow pipe 106c upon releasing or exerting pressure by the user on the piston rod 142. According to embodiments of the present invention, while achieving an unlocked position, there may be a chance of the piston 138 to rotate in one of, of the upward direction and/or the downward direction of the telescopic pole 104.
[0033] Further, the inner wall 136 may be surrounded by a piston ring 144, that may be designed to provide a seal between the cylinder 132 and the piston 138. The piston ring 144 may further enable an external slot of the piston 138 to slide freely inside the inner wall 136 of the cylinder 132, thereby restricts the rotation of the piston 138 in the outer wall 134 of the cylinder 132. Further, the piston rod 142 may be pushed and/or pulled by the user to insert and/or remove from the holes 108 (as shown in FIG. 1A) for locking and/or unlocking the telescopic pole 104 at the desired position. The push and/or pull operation of the piston rod 142 may extend and/or compress the spring 140 to lock and/or unlock the telescopic pole 104. In an exemplary scenario, wherein the piston rod 142 is pushed by the user, then the spring 140 may be extended to a pre-defined length to achieve the locked position. In another exemplary scenario, wherein the piston rod 142 is pulled by the user, then the spring 140 may be compressed to achieve the unlocked position.

Further, in a preferred embodiment of the present invention, the piston rod 142 may have a diameter (D2) of 10 mm. Further, in a preferred embodiment of the present invention, the spring 140 may have a diameter (D3) of 12 mm and a length (L2) of 25 mm.
[0035] FIG. 2 illustrates modules of the control unit 122, according to an embodiment of the present invention. The control unit 122 may comprise a data receiving module 200, a data processing module 202 and a gear control module 204.
[0036] The data receiving module 200 may be configured to receive the sensed signal of the water drops from the rain sensor 120, in an embodiment of the present invention. The data receiving module 200 may be configured to receive the sensed signal via a communication module (not shown). In an embodiment of the present invention, the communication module may be, but not limited to, a ZigBee, a 6LoWPAN, a Z-wave, a LM91-MV, and so forth. Embodiments of the present invention are intended to include or otherwise cover any type of the communication module, including known, related art, and/or later developed technologies. Further, the data receiving module 200 may be configured to transmit the received sensed signal to the data processing module 202.
[0037] The data processing module 202 may be configured to determine a numerical value based on the sensed signal of the water drops that may be compared with a pre-defined value stored in the memory 130. In an embodiment of the present invention, the data processing module 202 may be configured to generate a gear activation signal if the sensed value of the water drops is greater than or equals to the predefined value. In another embodiment of the present invention, the data processing module 202 may be configured to generate a gear deactivation signal if the data processing module 202 determines that the sensed value of the waterdrops is less than the predefined value, that may indicate there are no water droplets. Further, the data processing module 202 may be configured to transmit the generated gear activation signal and the generated gear deactivation signal to the gear control module 204, according to embodiments of the present invention.
[0038] The gear control module 204 may be configured to trigger the motor to rotate at the pre-defined speed that enables a rotation of the circular gear 118 in an anti-clockwise direction based on the received gear activation signal, in an embodiment of the present invention. Further, upon triggering the motor, the circular gear control module 204 may be configured to enable the movement of the linear gear 116 in the vertically upward direction to open the canopy 112 of the umbrella device 100.
[0039] Further, in another embodiment of the present invention, the gear control module 204 may be configured to enable the data receiving module 200 to continue to receive the sensed values from the rain sensor 120. Further, the gear control module 204 may be configured to enable the movement of the linear gear 116 in the vertically downward direction to close the canopy 112 of the umbrella device 100 based on the received gear deactivation signal.
[0040] FIG. 3 represents a flow chart of a method 300 for automatically opening and/or closing the umbrella device 100, according to an embodiment of the present invention.
[0041] At step 302, the umbrella device 100 may receive sensed signal associated with a presence of the water drops form the rain sensor 120.
[0042] At step 304, the umbrella device 100 may compare the sensed value associated with the presence of the water drops with a predefined value stored in the memory 130. If the umbrella device 100 determines the sensed value is greater than or equal to the predefined value, then the method 300 may proceed to a step 306, on the other hand if the umbrella device 100 determines that the sensed value is less than the predefined value, then the method 300 may return to the step 302.
[0043] Next, at the step 306, the umbrella device 100 may actuate the circular gear 118 to rotate in an anti-clockwise direction that enables the linear gear 116 to move freely in the upward direction to open the canopy 112 of the umbrella device 100.
[0044] Next, at the step 308, the umbrella device 100 may actuate the circular gear 118 to rotate in a clockwise direction that enables the linear gear 116 to move in the downward direction to close the canopy 112 of the umbrella device 100, in case the canopy 112 of the umbrella device 100 gets dried.
[0045] While the invention has been described in connection with what is presently considered to be the most practical and various embodiments, it is to be understood that the invention is not to be limited to the disclosed embodiments, but on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims.
