(14) The plate stack structure according to the embodiment of the present invention includes: a base 100; plate stacks 200 having a predetermined shape; a plurality of fixing parts 300 for fixing the plate stacks 200; and a cover 400 coupled to an end surface of an edge of the base, the cover holding the plate stacks therein.

(15) Referring to the drawings, the base 100 has a circular shape, and five fixing rods 320 pass through the base 100. The cover 400 having a bowel shape is fitted over the end surface of the edge of the base 100. Although the plate stack structure may be installed in various directions, the base 100 stands vertically according to the embodiment of the present invention. Accordingly, the plate stack structure may be mounted to an additional support while standing, so the cover 400 is coupled to the base 100 while standing. In addition, the cover 400 is provided with a plurality of cover through holes 410 on a top surface thereof, and thus the plate stack structure can efficiently transmit and discharge energy.

(16) FIG. 4 is a view showing shaped plates according to the embodiment of the present invention. FIG. 5 is a view showing plates according to the embodiment of the present invention.

(17) Referring to FIGS. 4 and 5, the plate stacks 200 include a plurality of plates 210 having predetermined shapes, and the plurality of plates 210 are arranged to be spaced apart from each other at predetermined intervals, or to come into surface contact with each other. The plates 210 include shaped plates 210a having shaped bodies, and space plates 210b placed between the shaped plates. The shaped plates 210a and the space plates 210b are provided with respective plate through holes 211 such that the fixing rod 320 of a fixing part 300 passes through the plate through holes 211 of the plates 210a and 210b of a plate stack 200.

(18) Each of the plates 210 constituting the plate stacks 200 may be made of metal that can efficiently discharge or transmit energy. Preferably, the metal may be aluminum, which is a relatively light metal.

(19) Referring to FIG. 4, the shaped plates 210a are formed by continuously arranging polygonal shaped bodies (designated by no reference numeral) such that the polygonal shaped bodies form a circular arrangement of the shaped plates 210a, with a space V defined at a center of the circular arrangement of the shaped plates 210a. In the embodiment, each of the shaped bodies has a heptagonal shape. The shaped bodies are arranged in radial directions at same distances and at same angles relative to the center of the circular arrangement of the shaped plates 210a.

(20) Although the space plates 210b have the same shape of the shaped bodies of the shaped plates 210a, the size of the space plates is smaller than the size of the shaped bodies of the shaped plates 210a. Each of the shaped plates 210a includes five shaped bodies. When the plate stacks 200 are formed by placing the space plate 210b between two shaped plates, five space plates are respectively arranged at locations corresponding to the shaped bodies of the shaped plates 210a. Here, the space plates are interposed between the shaped plates. For reference, FIG. 5 shows that the plates of a plate stack are fixed by a fixing rod, for ease of description of the embodiment of the present invention.

(21) Meanwhile, a plurality of shaped plates 210a and a plurality of space plates 210b may be stacked on each other, respectively, and the stacked shaped plates and the stacked space plates may be alternately stacked on each other to come into surface contact with each other.

(22) When stacking the shaped plates 210a and the space plates 210b, it is required to fix the plates 210a and 210b so as not to allow the plates from being separated from each other. To this end, the shaped bodies of the shaped plates 210a and the space plates 210b are provided with respective plate through holes 211 at centers thereof. Due to the plate through holes 211, the shaped plates 210a and the space plates 210b can be stacked on each other and can be arranged in a predetermined way by being fitted over the fixing rods 320.

(23) Hereinbelow, the fixing part according to the embodiment of the present invention will be described in detail.

(24) FIG. 6 is a view showing the fixing part of the plate stack structure according to the embodiment of the present invention. FIG. 7 is a view showing combination of the plates with the fixing part according to the embodiment of the present invention.

(25) According to the embodiment of the present invention, the plate stacks 200 are arranged by using five fixing rods 320. However, when forming the plate stacks 200 by arranging the plates having circular through holes by using fixing rods 320 having circular cross-sections, the fixing rods and the plates come into contact with each other at circular contact junctions, and thus arrangement of the plates may be easily disorganized by an external force.

(26) To prevent this, according to the present invention, the cross-section of the fixing rod 320 and the through holes of the plates may be configured to have polygonal shapes. Here, the polygonal shapes may be shapes having three or more angles. According to the embodiment of the present invention, the fixing rod 320 is configured to have a square cross-section. Additionally, the through hole of each of the plates has a square shape of a size corresponding to the size of the square fixing rod 320.

(27) The fixing part 300 of the plate stack structure according to the embodiment of the present invention is configured to include a head 310, the fixing rod 320, and a fastener 330.

(28) The head 310 has a shape of a heptagonal pyramid. The head 310 is configured to have a flat surface on a lower end surface thereof such that the head and the uppermost plate come into surface contact with each other, and the lower end surface is provided with a threaded hole in a center thereof such that a first screw part 321 of the fixing rod 320 is screwed to the threaded hole.

(29) The fixing rod 320 includes the first screw part 321, a body 322, and a second screw part 323. The body 322 of the fixing rod 320 is configured to have a square cross-section. The body 322 is provided between an upper part and a lower part of the fixing rod 320, and the first screw part 321 and the second screw part 323 are provided on the upper part and the lower part of the fixing rod 320, respectively. The fixing rod 320 is engaged with the head 310 at the first screw part 321 thereof, and is engaged with the fastener 330 at the second screw part 323 thereof.

(30) The plates of the plate stacks 200 are fitted over the fixing rod 320, and are tightly fastened to each other by the head 310 and the fastener 330. To be specific, after the first screw part 321 of the fixing rod 320 is screwed to the head 310, the plates of the plate stacks 200 are fitted over the body 322 of the square fixing rod 320, and the second screw part 323 of the fixing rod is coupled to a through hole of the base 100 and is fastened by the fastener.

(31) Referring to FIG. 7, the fixing rod 320 is engaged with the head 310 at the first screw part thereof such that the plates are not undesirably removed from the fixing rod. An outer diameter of the first screw part 321 is configured to be shorter than the length of a diagonal line of the square body 322 of the fixing rod 320. When the first screw part 321 of the fixing rod 320 is tightly screwed to the threaded hole formed in the lower end surface of the head 310, the first screw part 321 is not visible from the outside.

(32) FIG. 8 is a view showing an arrangement of the through hole of the plate and the head of the fixing part.

(33) Referring to FIG. 8, in the embodiment of the present invention, the plates and the shaped bodies are symmetrical relative to the centers of circular arrangements of the plates and the shaped bodies. In such a symmetrical structure, one side surface of the fixing rod 320 having predetermined angles and an outside surface of each of the plates are required to be parallel to each other so as to properly balance the structure.

(34) According to the present invention, the length of the threaded hole of the head 310 and the length of the first screw part 321 are configured to be exactly same such that the side surface of the body 322 of the square fixing rod 320 and a lower edge of the head 310 having a shape of a heptagonal pyramid are parallel to each other. Such a configuration enables the plate stack structure to balance itself relative to a center thereof.

(35) As shown in FIG. 8, a dotted line shown in an inner part of the shaped body indicates the edge of the lower end surface of the head 310, and L1, L2, and L3 indicate lines passing by an outside surface of the shaped body, the lower edge of the head 310, and a side surface of the through hole of the shaped body. Here, L1, L2, and L3 are parallel to each other.

(36) Meanwhile, the fastener 330 is fastened to the second screw part 323 of the fixing rod 320 so the plates come into close contact with the base 100. Here, the plates are configured to come into close contact with each other so as to increase precision. According to the embodiment of the present invention, the fastener 330 comprises a washer and a nut.

(37) Hereinbelow, a support plate 500 further provided in the plate stack structure according to the embodiment of the present invention will be described in detail.

(38) FIG. 9 is a view showing the support plate according to the embodiment of the present invention. FIG. 10 is a view showing positions of the support plates relative to a plate stack according to the embodiment of the present invention.

(39) The plate stack structure according to the present invention may be installed standing. In this case, weights of the plate stacks 200 concentrate on regions on which the plate stacks 200 and the fixing rods 320 are coupled to each other. Although the plate stack structure is mounted to fixed equipment instead of moving equipment, the fixing rod 320 may be easily deformed by the plate stacks 200 having the weights, and thus may separate from the base 100, or may be bent.

(40) The support plate 500 supports the plate stacks 200 coupled to the bodies of the fixing rods 320. Heavy weights of the plate stacks 200 applied in a gravitational direction may be changed depending on an angle at which the plate stack structure is fixed to equipment, and depending on a moving direction of the equipment. In this case, since the weights of the plate stacks 200 are applied to the fixing rods 320 supporting the plate stacks 200, it is necessary that the fixing rods are configured to be large in thickness, or a fixing plate of the equipment to which the fixing rods 320 are fixed is configured to be strong. Here, the fixing plate refers to a mounting surface of equipment to which the stack structure according to the present invention is mounted.

(41) In this present invention, considering distribution of weights, the plate stacks 200 are further provided with the support plate 500. The support plate 500 includes an upper support plate 510 and a lower support plate 520.

(42) Referring to the drawings, the upper support plate 510 is mounted between the plate stacks 200 and the heads 310. Plates of the upper support plate 510 have the same shapes of the plates of the plate stacks 200, and additionally, the upper support plate is integrally provided with a single circular ring part 511 on a circumference thereof. The ring part comes into contact with an inner surface of the cover 400 on an end surface thereof.

(43) An outer diameter of the support plate 500 and an outer diameter of the base 100 are same in length. A part except for a top surface of the cover 400 has a cylindrical shape, and a bottom part of the cover 400 is open. The bottom part is coupled to the end surface of the edge of the base 100 on an end part thereof, and the cover 400 is configured to come into contact with an outer circumferential surface of the support plate 500, that is, the surface of an edge of the ring part on the inner surface of the cover 400.

(44) The lower support plate 520 has a same shape of the upper support plate 510. The upper support plate 510 and the lower support plate 520 are different only in that they are mounted to different locations of the plate stacks 200. The upper support plate 510 is mounted between the plate stacks 200 and the head 310, and the lower support plate 520 is mounted to a position spaced apart from the upper support plate 510 at a predetermined interval. Preferably, the lower support plate 520 is mounted between the upper support plate 510 and the base 100.

(45) Although the support plate 500 is mounted between the plates of the plate stacks 200 as shown in the drawings, according to the embodiment of the present invention, the lower support plate 520 is mounted between the upper support plate 510 and the base 100. Considering securing a distance spaced apart from the upper support plate 510 and a size of the plate stack structure, the lower support plate 520 may be mounted in middle parts of the stacks 200. In addition, a middle support plate may be provided between the upper support plate 510 and the lower support plate 520.

(46) The upper support plate 510 and the lower support plate 520 distribute weights of the plate stacks 200. The plate stacks 200 stacked with a plurality of plates are heavy. When the plate stack structure is laid horizontally, the fixing rod 320 may be bent, or separated from the fixing plate by the stacks 200 having heavy weights. Ring parts 511, 521 formed on the upper support plate 510 and the lower support plate 520, respectively, come into surface contact with the cover 400 by coming into close contact with the inner surface of the cover on the end surface of the edge of each of the ring parts, thereby distributing weight that the fixing rod 320 supports.

(47) Although the preferred embodiment of the present invention has been disclosed for illustrative purposes, those skilled in the art will appreciate that various modifications, additions and substitutions are possible, without departing from the scope and spirit of the invention as disclosed in the accompanying claims.
