KR-20260063837-A - BOAT LANDING APPARATUS FOR SAFE OFFSHORE LAUNCHING OF SMALL SIZE BOAT

Abstract

The present invention relates to a boat landing device for the safe launching of a small boat at sea, and more specifically, to a boat landing device for the safe launching of a small boat at sea that allows a boat trailer loaded with a boat to be easily towed by a track-type trailer moving device, taking into account the characteristic of an inclined slipway being adjacent to the sea, thereby enabling the boat to be landed or launched. The present invention is characterized by comprising: a boat trailer (100) having a plurality of frames interconnected to load a boat on the upper part and a moving wheel (111) for movement mounted on the lower part; a balance unit (200) installed at the longitudinal rear of the boat trailer (100) to allow the rear of the boat trailer (100) to sink underwater when the boat loaded on the boat trailer (100) is landed on the water surface; and a track-type trailer moving device (300) that is movable by a track (331) with a position adjustment part (400) installed connected to a fixing connector (500) installed on one side of the longitudinal of the boat trailer (100), and is driven by a wired/wireless control device (320).

Claims (3)

1. A boat trailer (100) in which multiple frames are interconnected, a boat is loaded on the upper part, and wheels (111) for movement are mounted on the lower part; A balance unit (200) installed at the longitudinal rear of the boat trailer (100) to allow the rear of the boat trailer (100) to sink underwater when landing a boat loaded on the boat trailer (100) on the water surface; A boat landing device for safe sea launching of a small boat, characterized by comprising: a track-type trailer moving device (300) that is movable by a track (331) with a position adjustment part (400) installed on one side in the longitudinal direction of the boat trailer (100) and driven by a wired/wireless control device (320).
2. In paragraph 1, The above-described track-type trailer moving device (300) is characterized by comprising a body frame (310) having a communication control box (317) installed on the upper side, a plurality of track wheels (330) installed on both sides of the width direction of the body frame (310), a track drive unit (340) installed on the rear side of the body frame (310) to enable individual rotation of drive wheels (343) each connected to tracks (331) on both sides of the width direction, and a drive cylinder member (350) connected via a rod to a guide driven wheel (352) installed on the front side of the body frame (310) each connected to tracks (331) on both sides of the width direction.
3. In paragraph 2, The above position adjustment unit (400) is formed to extend upwardly on the front side of the body frame (310) and includes a support member (410) having a hook pin holder groove (411) formed at regular intervals along the longitudinal direction that penetrates from one side to the other side, a variable block (420) installed to be reciprocally movable along the longitudinal direction while wrapping around the support member (410) and having a plurality of pin installation holes (421) formed at regular intervals so as to be in communication with the hook pin holder groove (411), and a tow ball (430) formed protruding from one side of the variable block (420) and connected to a fixing connector (500) installed on the boat trailer (100), thereby forming a boat landing device for safe launching of a small boat at sea.

Description

Boat Landing Apparatus for Safe Offshore Launching of Small Size Boats The present invention relates to a boat landing device for the safe launching of a small boat at sea, and more specifically, to a boat landing device for the safe launching of a small boat at sea that allows a boat trailer loaded with a boat to be easily towed by a track-type trailer moving device, taking into account the characteristic of an inclined slipway being adjacent to the sea, thereby enabling the boat to be landed or launched. Recently, with the improvement of income levels and the reduction of working hours, a more diverse leisure culture is developing, and among them, water sports using boats that can be enjoyed on the sea or lakes are gaining popularity. Generally, a boat is a means of transportation that operates on water using a propeller driven by a motor, and it cannot move on land without a separate device such as a trailer. Accordingly, invention for moving a boat on land is disclosed in Registration No. 10-1489934 (Registration date: January 29, 2015). Upon examining the above patent, the boat trailer comprises: tires installed on steel plate springs at the lower sides of the middle section of the main frame to support the frame and drive on the road; a support stand installed on the upper side of the boat trailer where the tires are installed to support and place a boat on; a towing frame installed at the front end of the main frame to tow the boat trailer with a vehicle; a support wheel installed on one side of the towing frame to support the towing frame; and a wrench installed at the upper front end of the main frame to pull the boat up or slowly release it to lift or lower the boat into the water. The boat trailer is further composed of: a towing frame length adjustment device installed inside the towing frame and configured to extend the length by installing a spring between the towing frame and the main frame; a front wheel section installed at a position corresponding to the support wheel installed at the front of the towing frame; and a dumping device installed at the joint between the towing frame and the main frame, wherein the main frame connected to the towing frame rotates upward around the rear wheel. As described above, the trailer loaded with the boat is towed by a vehicle to the slipway, and then the boat is unloaded from the slipway so that it enters the sea. In other words, to launch the boat, the driver must reverse the vehicle to lower the trailer loaded with the boat into the water until the boat touches the surface. Once the boat is in the water, the driver then pushes the boat or releases the securing bars. After the boat is safely in the water, the vehicle must be moved forward to tow the trailer to land. During this process, the trailer's axle and the vehicle's axle connected to the trailer may also be submerged in water. If the trailer's axle and the vehicle's axle are submerged, oxidation can cause the wheels to detach from the axle or lead to corrosion. In addition, since the driver reverses the vehicle using only their senses to lower the trailer loaded with a boat into the water, there is a problem that if the trailer's axle slips off the slipway, the vehicle may also be dragged down and submerged. Accordingly, there is a need for the development of technology that enables boats loaded on trailers to be easily launched into the water without the use of vehicles.
