Description

[Detailed description of the invention] This invention is an oar support device for a rubber boat, in which a two-pronged oar support is pivotally mounted on a base mounted on the upper surface of the edge of the boat to removably support the oar handle. Regarding equipment.

Conventional technologies for oar support devices for rubber boats include a support ring or a pivot leg equipped with a cylindrical support metal, through which the oar handle is inserted, pivoted to a base mounted on the upper edge of the rubber boat. Alternatively, it is known that the oar is supported by fitting an insertion hole made in the oar handle into an oar support shaft set up on a base, but these oar support devices do not support the oar. It takes time and effort to attach and detach, which is inconvenient, and the oars move in the longitudinal direction when operating or rowing the oars. The purpose of the present invention is to provide an oar support device that eliminates the inconveniences and drawbacks of the conventional oar support devices, makes it easy to attach and detach the oars, and is easy to operate.

The present invention will be explained with reference to the embodiment shown in the drawings.
1 is a rubber base attached to the upper surface of the edge of a rubber boat; 2 is an elastic two-pronged oar support whose upper end is separated by a required distance and whose lower half is curved in an annular shape; 3 is a lower end pivot leg of the oar support. , 4 is a support to which the pivot leg 3 is pivoted, and support shafts 5 ₁ and 5 ₂ provided at both ends are respectively pivoted to the opposing surfaces of the base 1 . 6
is a retainer attached to the lower end of the pivot leg of the oar support,
7 is a groove wheel-shaped collar attached to the oar handle rod 8 with screws 9, and the outer diameter B of the groove bottom is slightly wider than the distance A between the upper ends of the two-pronged oar support at the bottom of both sides of the groove. A linear groove bottom 10 is provided for forming the groove.

Since the present invention is constructed as described above, in order to fit the oar separated from the oar support 2 onto the support, first the straight groove bottom of the groove wheel-shaped collar 7 attached to the handle rod is fitted. 10 is aligned between the two upper ends of the two-pronged oar support 2, and when the collar is pressed together with the oar from above, the two prongs of the support 2 are elastic and are pushed open from side to side, and the collar is pushed apart from the first As shown in the figure, it fits between the two annular prongs of the support metal and is supported in a freely rotatable manner. When removing the oar fitted to the oar support from the support, align the straight groove bottoms 10 on both sides of the collar 7 with the upper two prongs of the support, and then move the oar handle upwards. When the collar is pulled up forcefully, the upper part of the two-pronged support is pushed open against the elastic force, so that the collar can be easily removed from the support 2.

As mentioned above, the oar handle can be easily attached to and removed from the two-pronged support, and once the collar is fitted to the support, not only will it not come off accidentally while the oar is being operated, The collar is screwed onto the oar handle rod, so if you want to adjust the position where you put your hand on the oar or its length, you can change the collar mounting position by loosening the screw. This makes it easier to row the oars, and the support 2 has a pivot leg 3 pivoted on a support 4, which can also freely rotate on both sides of the base 1. Because it is pivoted like this, the oars can be operated extremely freely without any resistance.
Therefore, the present invention is particularly effective as an oar support device for rubber boats.

Claims (1)

[Scope of utility model registration request] A support that rotatably supports the lower end pivot leg of a two-pronged oar support, which has an elastic two-pronged oar support whose upper end is separated by a required distance and whose lower half is curved in an annular shape, on a base mounted on the upper surface of the edge of a rubber boat. A groove wheel-shaped collar that fits inside the annular curved part of the oar support is screwed to the appropriate position of the oar handle rod, and the upper end of the two-pronged oar support is attached to the bottom of the groove on both sides of the collar. An oar support device for a rubber boat, characterized in that a straight groove bottom is formed to form a groove bottom outer diameter that is slightly wider than the interval between.
