Definitions

• the present invention relates, in general, to rotary magnets and fastening pins for block toys, in which blocks are connected to each other using magnetic force to form structures having various shapes, and, more particularly, to a rotary magnet and a fastening pin for block toys for which the production cost is reduced, which can be easily installed in a block, and which can easily generate the correct attractive force between blocks, compared to conventional block toys using permanent magnets and holders.
• Background Art
• magnets generate magnetic force. When two magnets are close to each other, the magnetic force acts as an attractive force between unlike poles (between an N pole and an S pole), thus pulling the magnets towards each other, and the magnetic force acts as a repulsive force between like poles (between N poles or between S poles), thus pushing the magnets away from each other.
• the blocks 1 can be connected to each other or stacked on top of one another by uniting them using the attractive force between the permanent magnets, thereby forming various structures. Therefore, the block toy can be used as toys that enhance the creativity of children and promote the children's education.
• the conventional permanent magnets 20 and the holders 21, which are used in the blocks 1 are constructed such that the permanent magnets 20 are installed in the respective holders 21, as shown in FIG. 6, and the holders 21 are force-fitted into the insert hole 2 of the blocks.
• the conventional art is problematic in that the holders 21, which have been force-fitted into the block 1, may be undesirably removed from the block 1 after repeated use for a long period of time.
• the permanent magnets 20 may be oriented such that repulsive force therebetween is generated.
• one permanent magnet 20 must be turned upside down or rotated with respect to the other magnet to generate attractive force.
• an object of the present invention is to provide a fastening pin (11) and a rotary magnet (12) for block toys, the fastening pin (11) taking the place of the holder (21) of the prior art, being prevented from being undesirably removed from a block (1), and being easily assembled with the block, and the rotary magnet (14) being rotatably fitted over the fastening pin (11), wherein,
• the present invention provides a rotary magnet and a fastening pin for block toys, in which blocks are connected to each other using permanent magnets, wherein the fastening pin (11) includes: a fastening plate part (12) having a diameter suitable to fit the fastening plate part into a seating depression (2) of a block (1); and a pin part (13), having a height greater than a height of the rotary magnet (14), and the rotary magnet (14) has an N pole and an S pole on left and right parts thereof, with a through hole (15) formed through a central portion of the rotary magnet (14), so that the pin part (13) is inserted into the through hole (15).
• the fastening pin (11) includes: a fastening plate part (12) having a diameter suitable to fit the fastening plate part into a seating depression (2) of a block (1); and a pin part (13), having a height greater than a height of the rotary magnet (14), and the rotary magnet (14) has an N pole and an S pole on left and right parts thereof,
• a tool insert groove (18) for insertion of a tool may be formed in the fastening plate part (12) of the fastening pin (11), and an external thread (16) may be formed on the pin part (13).
• a hook (17) may be provided on an end of the pin part (13).
• a fastening pin (11) and a rotary magnet (14) for block toys according to the present invention can be firmly coupled to and easily removed from the block, unlike the conventional block toy, which uses a permanent magnet 20 and a holder 21. Therefore, there are advantages in that productivity is enhanced and the rotary magnet (14) can be easily replaced with a new one.

• FIG. 2 is a perspective view illustrating another embodiment of the present invention.
• FIG. 3 is a perspective view showing an example of the installation of the present invention to a block
• FIG. 4 is sectional views illustrating the rotation of a rotary magnet of the present invention, which is installed in the block;
• FIG. 5 is sectional views showing various shapes of pins according to the present invention.
• FIG. 6 is a perspective view showing a permanent magnet and a holder of a conventional block toy.
• FIG. 7 is a perspective view showing an example of the conventional block toy.
• the fastening pin 11 includes a fastening plate part 12, which has a diameter suitable to firmly fit it into a corresponding seating depression 2 of a block 1, and a pin part 13, which has a height greater than that of the rotary magnet 14.
• the rotary magnet 14 has an N pole and an S pole on the left and right parts thereof.
• the fastening pin 11 has a shape similar to a thumbtack.
• the diameter and thickness of the fastening plate part 12 are, respectively, approximately 6mm and 0.3mm, and the height of the pin part 13 is approximately 4mm.
• the fastening pin 11 is preferably made of stainless steel (SUS304) or SECC steel, which is plated with innoxious material.
• the diameter and height of the rotary magnet 14, respectively are about
• the coupling force between the present invention and the block 1 can be increased through the following additional construction.
• a tool insert groove 18 is formed in the fastening plate part 12 of the fastening pin 11, so that a tool such as a screwdriver can be inserted into the tool insert groove 18.
• An external thread 16 or a hook 17 is provided on the pin part 13.
• the pin part 13 of the fastening pin 11 is inserted into the through hole 15 such that the rotary magnet 14 is fitted over the pin part 13. Thereafter, the fastening pin 11 is force-fitted into the seating depression 2 of the block 1. At this time, the end of the pin part 13 is driven into the block 1, which is made of wood or synthetic resin, in order to firmly fasten the fastening pin 11 to the block 1.
• the rotary magnet 14 is fitted over the pin part 13 so as to be rotatable in a clockwise or counterclockwise direction, without adhering to the inner surface of the seating depression, and the rotary magnet 14 is thus prevented from being turned upside down. Therefore, there is an advantage in that attractive force can always be reliably generated between corresponding rotary magnets of two blocks.
• the end of the pin part 13 of the fastening pin 11 may have a pointed shape or a structure provided with the external thread 16.
• the end of the pin part 13 may have the shape of the hook 17.
• the pin part 13 may be modified to have various shapes, as well as a hook shape. Such modification must be regarded as falling within the scope and spirit of the present invention.
