WO2018163034A4 - Articulated oar controlled from the handle - Google Patents

Abstract

The present invention relates to the performance of transport operations involving vessels and related devices, and concerns an instrument for propulsion by means of muscular power, specifically an articulated oar with an internal mechanism in the handle. The oar contains a concentric shaft that is manipulated by a rigid perpendicular handle that allows, by means of a slot in the tube of the oar, the shaft to move so that, by means of a channel, same transfers movement to the end of the paddle, which, by means of a joint, allows the paddle to be secured or released in both directions and even secured for use as a conventional oar. The central shaft is repositioned by a spring.

Claims

 one MODIFIED CLAIMS  received by the International Office on August 24, 2018 (08/24/2018) 1 - Articulated oar controlled from the handle CHARACTERIZED consists of a handle with hollow tubular body (1 1) with a longitudinal rod (12) concentric to the tubular body (1 1) having a lever (13) perpendicular for finger operation of the user; wherein the longitudinal rod (12) has an internal termination (15) in a spring (16) for manipulating the rod (12) in compression and return to its locking position of a blade (17) according to the selected position of the blade (17) which determines three locking positions: a position called front (20) for forward movement of the boat, a so-called rear position (19) for backward movement of the boat and a position called straight (21) that locks the oar as an oar traditional without removing it from the water; wherein said longitudinal rod (12) is retractable and with concentric rotation in the latch (22), whose retractable movement (23) is longitudinal inside the tubular body (11) and has its longitudinal stop in the intermediate slot (24) and the concentric turn (25) has its top in the insurance (22).  2- Articulated controlled rowing from the handle according to claim 1 characterized in that the tubular body (1 1) has a rowing mechanism (14) of the oar (10) to the boat for articulated fixation without the need to remove the oar (10) of water in its operation or change of direction.  3- Controlled articulated remover from the handle according to claim 1 CHARACTERIZED because the internal end of the longitudinal rod (12) has a termination in the spring (16) and the external termination (26) of the longitudinal rod (12) protrudes from the body tubular (1 1) to lock the pallet (17) in the determined position.  4- Articulated remover controlled from the handle according to claim 1 CHARACTERIZED because the articulated vane (17) has a hinge (27) with a pin (28) that fulfills the pivot function of the hinge (27) and support for The type of lock chosen either a position called front (20) to advance the boat or a position called posterior (19) for recoil or a position called straight (21).

DECLARATION ACCORDING TO ARTICLE 19 (1)

- It is accepted that it has novelty and industrial application in claims 1, 2, 5 and that the invention may have an inventive step in claims 3, 4.

- Claim 1 is corrected by presenting the inventive level characteristics of the initial claim 3 now in the new modified claim 1.

 - The initial claim 3 is eliminated.

- The expression "has an angle between zero and 30 ^e of freedom" that reduces the clarity of the claim is eliminated.

 - It is clarified that as mentioned in claim 1, there are three locking positions, so that the initial claim 5 now modified claim 4 is corrected.

 According to the figures, the three locking positions are observed, a position called front (20) to advance the boat, a position called rear (19) to retract the boat and a position called straight (21) that locks the boat. rowing like a traditional paddle without removing it from the water.
