Description

  The present invention relates to a surfboard rudder assembling apparatus that can swiftly assemble a surfboard rudder using a structure that can be positioned and locked in a sliding manner.

  Currently, surfing is a fairly popular offshore movement at sea, and surfboards are constantly being offered new products in terms of modeling and improvements in functionality for use. FIG. 1 shows that a surfboard 1 is provided with a good water breaking action and has a plurality of fin-shaped rudder 2 attached to the bottom surface of the surfboard 1 in order to have good stability during surfing. The surfing direction can be controlled. The rudder 2 is attached so that it protrudes from the bottom of the surfboard in an assembling manner, so that when not in use, the user can remove the rudder 2 and carry it, and can be assembled at the site when in use. The convenience of is quite important. FIG. 2 is a technique described in Patent Document 1, which includes a plurality of receiving holes 11 provided on the bottom surface of the surfboard 1 to fix the positioning device 3, and each positioning device 3 has an insertion groove 31 recessed and inserted. Screw holes 32 that pass through the insertion groove 31 obliquely are provided on both sides of the groove 31, are used for screwing of the bolts 4, and are fitted blocks at positions corresponding to the insertion grooves 31 of the positioning device 3 on the bottom surface of the rudder 2. 21 is projected, and when the rudder 2 is assembled, the fitting block 21 of the rudder 2 is inserted into the insertion groove 31 of the positioning device 3, and the bolt 4 is screwed inward with a hand-held tool and fitted. The rudder 2 is assembled to the bottom surface of the surfboard 1 and positioned. When removing the rudder 2, the bolt 4 is also turned off with a hand-held tool, and the press contact with the fitting block 21 is released to separate the rudder 2 and the surfboard 1. However, the positioning method of this rudder and surfboard is the positioning by the pressure contact of the bolt, and it is necessary to turn the bolt with a hand-held tool for both assembly and removal work. The pressure contact area is small, the fitting block 21 of the rudder 2 is easily damaged, and the pressure contact force is small. Therefore, improvement is required.

The rudder assembling device for a surfboard is characterized by receiving the locking of the restriction convex block.

  The surfboard rudder assembly device of the present invention is provided with a locking device on the bottom surface of the surfboard, a fitting groove having a predetermined depth is provided on the locking device, and at a predetermined pitch on the top surface of the fitting groove. Position restricting protrusions are distributed, an engaging device is provided on the bottom surface of the rudder, and a locking block is provided on the engaging device at a predetermined pitch. When the rudder is assembled, the engaging device is fitted to the locking device. Inserted in the mating groove, the locking block of the engagement device corresponds to the position restriction convex block on the upper surface of the fitting groove, the position of the engagement device is restricted in the fitting groove, and the assembly and positioning of the rudder are completed As a result, the practical effect of rapid assembly is achieved.

  As shown in FIGS. 3 and 4, a plurality of receiving holes 51 are formed in the bottom surface of the surfboard 5 of the present invention, and a plurality of locking devices 6 are separately provided in the receiving holes 51 after a binder is applied to the periphery. The locking device 6 is fixed to the bottom surface of the surfboard 5 by being press-fitted. Among them, each locking device 6 is provided with a recessed groove 61 having a predetermined depth, width and length, and a plurality of sets of protruding grooves are provided at a predetermined pitch at the upper surface position of the engaging groove 61. Position limiting convex masses 62 and 63 are provided, and an opening distance is provided between the two position limiting convex masses 62 and 63. The engaging device 71 is extended from the bottom surface of the rudder 7, the length of the engaging device 71 is shorter than the length of the fitting groove 61, and the same distance as the distribution distance of the position-limiting convex masses 62 and 63 of each set. A plurality of sets of locking blocks 72 and 73 are provided on both sides, and the widths of the locking blocks 72 and 73 on both sides of the engagement device 71 are the same as the groove width of the fitting groove 61.

  As shown in FIGS. 5 and 6, when the rudder 7 is assembled in the present invention, the groove width of the fitting groove 61 is the same as the widths of the locking blocks 72 and 73 on both sides of the engaging device 71. The positions of the locking blocks 72 and 73 of the coupling device 71 are made to correspond to the portions of the fitting groove 61 where the position restricting convex blocks 62 and 63 are not present, and the engaging device 71 is inserted into the fitting groove 61 and both sides The locking blocks 72 and 73 are placed at a position lower than the position restricting convex blocks 62 and 63 below the fitting groove 61.
