Description

BACKGROUND OF THE INVENTION

1. Field of the Invention
This invention relates to a boat rowing device. The boat rowing device is useful to propel a boat in water.
2. Description of the Prior Art
Boats are propelled in water generally by using a plurality of oars adapted to be supported on both sides of a boat pivotally with the help of an iron loop or saddle. The boat is propelled by the boat operator by pulling the oars towards him and thus the water is pushed forward and the boat moves in the backward direction. In such a situation the boatman is unable to navigate the boat by himself. However, if the boatman wants to navigate the boat himself then he has to push the oars in the forward direction and thus water is pushed in the backward direction and the boat moves in the forward direction.
In western countries during boats race the oarsman do pull the oars towards themselves and therefore the boat moves in the backward direction. Thus, the oarsmen can not themselves navigate the boat. Therefore, a trained operator/navigator is needed to navigate the boat in the water during such races. However, if the oarsmen want to navigate the boat by self then they have to push the oars to move the water in backward direction and therefore get exhausted soon.
Therefore, a boat rowing device, according to this invention, is proposed which is of light weight and high strength. Also, the operation of the boat rowing device and maintenance thereof is easy. Further, the device can be operated by an untrained person. Thus, the disadvantages associated with the prior art have been obviated by the device of the present invention.

SUMMARY OF THE INVENTION

According to an embodiment of this invention a boat rowing device comprises a driving gear secured rotatably to a plate adapted to be secured to a side of the boat. A driven gear is secured to the plate such that to receive rotational movement from the driving gear. A handle is secured with the driving gear to rotating the driving gear. An oar is secured with the driven gear to facilitate rowing of the boat.

BRIEF DESCRIPTION OF THE DRAWINGS

A boat rowing device according to a preferred embodiment is herein described and illustrated in the accompanying drawings wherein;

DETAILED DESCRIPTION OF THE INVENTION

A boat rowing device is herein described with numerous specific details so as to provide a complete understanding of the invention. However these specific details are exemplary details and should not be treated as the limitation to the scope of the invention. The invention may be performed with slight modifications.
Throughout this specification the word “comprise” or variations such as “comprises or comprising”, will be understood to imply the inclusions of a stated element, integer or step, or group of elements, integers or steps, but not the exclusions of any other element, integer or step or group of elements, integers or steps.
Referring to FIG. 1, the boat rowing device A comprises a gear wheel 1 secured rotatably to a plate 2 and constitute a driving gear. Another gear wheel 3 is secured to the plate 2 rotatably such that to be engaged with gear wheel 1 so as to receive rotatable movement from the gear wheel 1 and constitute a driven wheel. A handle 4 is secured to the gear wheel 1 to facilitate pulling or pushing of the wheel 1 on its axis and thus to rotate the gear wheel 3. An oar 5 is secured to the gear wheel 3 which pushes water back ward upon receiving drive from the gear wheel 1. The plate 2 is adapted to be secured near top end of the side of the boat so that it can be operated by the user of the boat.
In one embodiment, plate 2 is hingedly secured to a base plate 6. The base plate 6 is adapted to be secured at the top surface of the side of the boat such that to raise and lower the oar 5 in the water as and when required so as to facilitate rowing of the boat.
According to an embodiment a third gear wheel (not shown) may be provided between the gear 1 and 3 to increase and/or decrease rotation of the gear wheel 3 and thus to increase or decrease speed of rowing of the boat. Also, the third gear wheel is provided between the driving gear and the driven gear such that to reverse rotational movement of the driven gear so to row the boat in the desired direction.
As shown in FIG. 2, the device A is secured on both sides of a boat B and the user or users of the boat pulls the handle 4 towards himself/herself and thus the gear wheel 1 is rotated and in turn the gear wheel 3 is rotated and the oar 5 thus pushes water in the backward direction and the boat moves in the forward direction. This operation is repeated continuously for rowing the boat.
In one embodiment the user or users of the boat may push the handle 4 away from himself/herself and thus the gear wheel 1 is rotated in the reverse direction and in turn the gear wheel 3 is rotated and the oar 5 thus pushes water in the forward direction and the boat moves in the backward direction. This operation is repeated continuously for rowing the boat.
Certain features of the invention have been described with reference to the example embodiments. However, the description is not intended to be construed in a limiting sense. Various modifications of the example embodiments as well as other embodiments of the invention, which are apparent to the persons skilled in the art to which the invention pertains, are deemed to lie within the spirit and scope of the invention.
