The present invention relates to a sliding bracket device for a guide motor that is capable of allowing a slide frame part to slide on a fixed frame part so that the guide motor disposed on top of the slide frame part is selectively located inside and outside a boat according to the sliding directions of the slide frame part.
Hereinafter, an explanation of a sliding bracket device for a guide motor according to the present invention will be given in detail with reference to the attached drawings.
Referring to
The sliding bracket device for a guide motor according to the present invention is installed on the bow or stern of a boat 10 to connect the guide motor 20 to the boat 10, and in a state where the guide motor 20 is located on the slide frame part 200, the slide frame part 200 slides on the fixed frame part 100 by a user's control.
Accordingly, the fixed frame part 100 is installed on the bow or stern of the boat 10.
In specific, the fixed frame part 100 is installed on the bow or stern of the boat 10, on which the slide frame part 200 as will be discussed later slides, so that the fixed frame part 100 is coupled to the boat 10, without any shaking, to allow the slide frame part 200 to easily slide thereon in a state where the slide frame part 200 is disposed thereon.
The fixed frame part 100 has the shape of a rectangle, but according to embodiments of the present invention, the fixed frame part 100 may be freely changed in shape only if the slide frame part 200 disposed on top thereof easily slides thereon.
The slide frame part 200 is disposed to slide on top of the fixed frame part 100 and configured to install the guide motor 20 thereon.
In the case where the slide frame part 200 slides in one side direction thereof, it is configured to allow the guide motor 20 to be located inside the boat 10, and contrarily, in the case where the slide frame part 200 slides in the other side direction thereof, it is configured to allow the guide motor 20 to be located outside the boat 10.
In specific, the slide frame part 200 slides on top of the fixed frame part 100 according to the user's control, so that the guide motor 20 installed on the slide frame part 200 is selectively located inside and outside the boat 10.
Further, the slide frame part 200 includes a pair of guide members 210 coupled to the undersides of both sides thereof to extend in a direction toward the fixed frame part 100, and the fixed frame part 100 includes a plurality of shafts 110 coupled to top thereof in a direction perpendicular thereto and guide rollers 120 rotatably coupled to the outer peripheral surfaces of the shafts 110, respectively, to the shapes coming into contact with the guide members 210 so that if the slide frame part 200 slides, the guide rollers 120 rotate around the shafts 110 by means of the guide members 210.
If the slide frame part 200 slides, that is, the guide members 210 of the slide frame part 200 come into contact with the guide rollers 120 and thus slide together with the slide frame part 200, and accordingly, the guide rollers 120 rotate by means of the sliding movements of the guide members 210 to guide the sliding movements of the guide members 210.
In this case, each guide member 210 has the shape of a rod with a circular section, and the guide rollers 120 whose surfaces coming into contact with the guide members 210 have the corresponding shapes to the shapes of the guide members 210, so that the guide rollers 120 rotate by means of the sliding movements of the guide members 210, while inserting portions of the guide members 210 thereinto.
In more specific, the guide rollers 120 whose surfaces coming into contact with the guide members 210 have the corresponding shapes to the circular shapes of the guide members 210, and when the surfaces of the guide rollers 120 coming contact with the guide members 210 extend to have imaginary circular shapes, diameters of the imaginary circular shapes are larger than the diameters of the circular shapes of the guide members 210, so that an excessive force needed when excessive contacts occur between the guide rollers 120 and the guide members 210 is not required for the sliding movements of the guide members 210.
Like this, four shafts 110 and four guide rollers 120 are needed to guide the sliding movements of one pair of guide members 210, and they are disposed on the corners of top of the fixed frame part 100.
Further, the slide frame part 200 includes connection members 220 disposed on one end and the other end of the guide members 210 to connect the guide members 210 to each other, thereby preventing a distance between the guide members 210 from being varied, and the connection members 220 have stoppers 221 adapted to limit the sliding distances of the slide frame part 200 during the sliding movements of the slide frame part 200.
The connection members 220 connect the pair of guide members 210 to each other to prevent the distance between the guide members 210 from being varied, so that while the guide members 210 are sliding, they are easily guided by means of the guide rollers 120.
The stoppers 221 extend from the connection members 220 toward the fixed frame part 100 to cover at least portions of the fixed frame part 100.
In specific, the stoppers 221 are locked onto the fixed frame part 100 to limit the moving distance of the slide frame part 200 during the sliding movements of the slide frame part 200.
For example, if the slide frame part 200 slides in one side direction thereof, the stoppers 221 of the connection members 220 are locked onto the other side of the fixed frame part 100 to limit the sliding movement of the slide frame part 200, and if the slide frame part 200 slides in the other side direction thereof, the stoppers 221 of the connection members 220 are locked onto one side of the fixed frame part 100 to limit the sliding movement of the slide frame part 200.
Further, each guide member 210 has one or more slide fixing grooves 211 formed thereon in a longitudinal direction thereof, and the fixed frame part 100 includes extension portions 130 protruding therefrom to cover at least portions of the guide members 210, through holes 140 formed on the extension portions 130, and slide fixing pins 150 inserted into the through holes 140 and the slide fixing grooves 211 to prevent the sliding movements of the guide members 210.
That is, the slide fixing pins 150 pass through the through holes 140 of the extension portions 130 and the sliding fixing grooves 211 to prevent the guide members 210 from sliding, and according to the positions of the slide fixing grooves 211 formed on the guide members 210, the fixed positions of the guide members 210 are determined.
For example, the slide fixing grooves 211 are formed on one side ends of the guide members 210, and if the slide frame part 200 slides in the other side direction thereof, the slide fixing pins 150 are inserted into the slide fixing grooves 211 so that the guide members 210 are fixed in position. Further, the slide fixing grooves 211 are formed on the middle portions of the guide members 210, and if the slide frame part 200 slides in one side direction thereof, the slide fixing pins 150 are inserted into the slide fixing grooves 211 so that the guide members 210 are fixed in position.
According to the present invention, the two slide fixing grooves 211 are formed on the guide members 210, respectively, and if the slide frame part 200 slides in one side and the other side direction thereof, the slide fixing pins 150 are inserted into the slide fixing grooves 211. According to embodiments of the present invention, however, two or more slide fixing grooves 211 may be formed on the guide members 210, respectively, and accordingly, the guide motor 20 may be freely set in position according to the sliding movements of the guide members 210.
Further, the slide fixing pins 150, which are inserted into the through holes 140 of the extension portions 130 and the slide fixing grooves 211 of the guide members 210, apply elastic forces in directions where the through holes 140 and the slide fixing grooves 211 are formed, and if the through holes 140 and the slide fixing grooves 211 are concentric with each other according to the sliding movements of the guide members 210, accordingly, the slide fixing pins 150 are automatically inserted into the through holes 140 and the slide fixing grooves 211.
In specific, the slide fixing pins 150 always move in the directions where the through holes 140 and the slide fixing grooves 211 are formed by means of the elastic forces, and if it is desired to slide the slide frame part 200, accordingly, the slide fixing pins 150 initially escape from the through holes 140 and the slide fixing grooves 211. After the slide frame part 200 slides, even though the slide fixing pins 150 are released from the user's hands, they are not inserted into the through holes 140 and the slide fixing grooves 211 if the slide frame part 200 does not slide to a pre-determined position, so that it is easy to control the slide fixing pins 150.
For example, if it is desired to slide the slide frame part 200, the slide frame part 200 slides in the state where the sliding fixing pins 150 initially escape from the through holes 140 and the slide fixing grooves 211, and in this case, even though the slide fixing pins 150 are released from the user's hands, they are in a stand-by state until the slide frame part 200 slides to a desired position. After that, if the slide frame part 200 slides to the desired position, the slide fixing pins 150 are inserted into the slide fixing grooves 211 of the guide members 210, respectively, by means of their elastic force.

In specific, the rotation fixing pin 330, which is adapted to pass through the fixed frame part 100 and the fixed plate 310 to fix the rotation of the fixed frame part 100, is inserted into any one of the plurality of fixing holes 312 and the first through hole 160, so that the fixed frame part 100 rotates to a desired angle by the user and is then fixed.
The fixed frame part 100 is configured to rotate by an angle formed by the plurality of fixing holes 312 of the fixed plate 310, and according to embodiments of the present invention, the fixed frame part 100 can rotate by an angle of 45° in left and right directions. The plurality of fixing holes 312 are spaced apart from one another by intervals of 5 to 10°, thereby enabling the rotating angle of the fixed frame part 100 to be precisely controlled.
In this case, the rotation fixing pin 330, which is adapted to pass through the fixed frame part 100 and the fixed plate 310, applies an elastic force in a direction where the fixing holes 312 and the first through hole 160 are formed, that is, in a downward direction, like the slide fixing pins 150, and if any one of the fixing holes 312 and the first through hole 160 are concentric with each other according to the rotation of the fixed frame part 100, accordingly, the rotation fixing pin 330 is automatically inserted into any one of the fixing holes 312 and the first through hole 160.
