And may be exaggerated, simplified, or omitted to clearly illustrate the invention in the drawings. Also, the singular expression includes plural.

FIG. 1 is a perspective view of a laminated structure according to an embodiment of the present invention, FIG. 2 is a perspective view showing a cover of a laminated structure according to an embodiment of the present invention, FIG. 3 is a cross- And Fig.

A laminated structure according to an embodiment of the present invention includes a base 100, a laminate 200 having a predetermined shape, a fixing portion 300 for fixing the laminate, And a cover 400 incorporating a laminate.

Referring to the drawings, the base 100 is circular and has five fixing rods fitted therein. And a bowl-shaped cover 400 is coupled to the end surface of the base. The laminated structure may be installed in various directions, but the base according to the present invention is vertically erected. Therefore, since the laminated structure can be installed on a separate support in a raised state, the cover coupled to the base is also vertically coupled. In addition, a plurality of through holes 410 are formed in the front surface of the cover to facilitate transmission and discharge of energy.

Hereinafter, a laminate according to an embodiment of the present invention will be described in detail with reference to FIG.

FIG. 4 (a) is a view showing a shape plate according to an embodiment of the present invention, and FIG. 4 (b) is a view showing a space plate according to an embodiment of the present invention.

Referring to the drawings, the laminated body 200 is formed of plates having a predetermined shape, and the plurality of plates are spaced apart from each other or mutually contacted with each other. The plate includes a shape plate 210 including a shape body and a space plate 220 interposed between the shape plate and the shape plate. The shape plates and the space plate are provided with holes 210h and 220h through which the fixing rods of the fixing portions are inserted.

The plate constituting the laminate may be constituted of a metal which facilitates energy radiation or energy transmission. Preferably, the metal may be formed of aluminum, which is a relatively light metal.

Referring to FIG. 4A, the shape plate 210 has a circular shape formed by successively forming a polygonal shaped body (not numbered), and a space portion V is formed at the center thereof. The body has a hexagonal shape. Each of the shaped bodies are all arranged in a radial shape so as to have the same distance and the same angle from the center of the shape plate.

The space plate 220 has the same shape as that of the shape plate 210, but the size of the space plate 220 is smaller than that of the shape plate formed on the shape plate 210. The space plate is formed by separating five shape bodies. In the same manner as the shape plate, a space V is formed at the center thereof.

Referring to Fig. 4 (b), the shape of the space plate is smaller than the shape of the shape plate. In the figure, the hexagonal shape of the solid line shows the shape of the space plate, and the broken line of the hexagonal shape shows the shape of the shape plate.

 If a laminate is to be formed between the two shape plates through the space plate, the five shape plates of the space plate are aligned and interposed at positions corresponding to the shape of the shape plate. For reference, the shape plate and the space plate may be stacked in a plurality of layers, and the stacked shape plate and the space plate may be alternately in surface contact.

The shape plate and the space plate are fixed so as not to be separated from each other. For this purpose, holes 210h and 220h are formed at the centers of the shape plates and the space plate. The fixing rod is fitted in the hole, and the shape plate and the space plate are stacked and arranged uniformly.

On the other hand, a support plate may be interposed between the shape plate and the space plate. The support plate firmly fixes the laminate on the inner surface formed of the base and the cover, and prevents the movement of the laminate due to external force.

5 is a view illustrating a support plate according to an embodiment of the present invention.

Meanwhile, the laminated structure according to the present invention may be installed in a raised form. At this time, the load of the laminate is concentrated at the point where the fixing rods are coupled. Even though the laminated structure is not mounted on a moving device but mounted on a fixed device, the fixing rod can be easily deformed and deviated or bent from the base due to a stacked body having a load.

The support plate supports a laminated body coupled to the body of the fixed bar. A stack having a considerable load may have different loads acting in the direction of gravity depending on its fixed angle and in the moving direction. The load acting at this time acts on the fixed bar supporting the laminate, so that the thickness of the fixed bar or the fixed plate of the fixed device should be designed robustly. Here, the fixing plate refers to a mounting surface of a device on which the laminated structure according to the present invention is mounted.

In the present invention, the support plate 230 is further provided in the laminate in consideration of dispersion of load. The support plate includes an upper support plate 231 and a lower support plate 232.

Referring to the drawings, an upper support plate is interposed on the upper side of the laminate (the direction in which the head is formed). The upper support plate 231 includes the same shape as the plate of the laminate, and further, a single circular ring 231r is further formed on the outer periphery of the upper support plate to be integrally formed. And the end face of the ring portion is in contact with the inner face of the cover. In other words, the outer diameter of the support plate is the same as the inner diameter of the cover.

The outer diameter of the support plate is the same as the outer diameter of the base. Referring back to FIG. 2, the cover according to the present invention has a circular shape except the front face of the cover, and the back face of the cover is opened. The back side end portion is coupled to the outer circumferential surface of the base and is configured to contact the outer circumferential surface of the support plate, that is, the outer circumferential surface of the ring portion.

The lower support plate 232 has the same shape as the upper support plate. However, only the upper support plate and the lower support plate are mounted at different positions in the laminate. The upper support plate is mounted on the upper side of the laminate, and the lower support plate is mounted on the lower side of the laminate. That is, the lower support plate is mounted at a position spaced apart from the upper support plate by a predetermined distance. Preferably, the lower support plate is mounted in the middle of the laminate between the upper support plate and the base.

Although it is shown in the drawings, the support plate is formed between the plates of the laminate. However, it may be mounted in the middle of the laminated body in consideration of the distance between the upper supporting plate and the lower supporting plate, the size of the laminated structure, and the like. Preferably, the upper support plate may be formed between the head and the laminate, and the lower support plate may be formed between the laminate and the base.

The upper support plate and the lower support plate distribute the load of the laminate. The laminate in which a plurality of plates are laminated is heavy. If the laminated structure is laid down and placed vertically, the fixing rod may be bent or detached from the fixing plate due to the laminate having a heavy load. The edge end faces of the hooks 231r and 232r formed on the upper support plate and the lower support plate are brought into surface contact with the inner surface of the cover to disperse the load received by the fixing rods.

Hereinafter, a fixing unit according to an embodiment of the present invention will be described in detail.

FIG. 6 is an exploded perspective view illustrating a fixing unit according to an embodiment of the present invention, FIG. 7 is a view showing a plate coupled to a fixing unit according to an embodiment of the present invention, FIG. 8 is a cross- Fig.

In the present invention, the stacked bodies are aligned using five fixed rods. However, if a stationary rod having a circular cross section is used and plates having circular holes are aligned to form a laminate, since the fixing rod and the plates are formed in a circular shape, the plates are easily misaligned by external force.

In order to prevent this, in the present invention, both the fixing rod and the hole of the plate can be formed into a polygonal shape. Here, the polygonal may be a shape having an angle of triangular or more. In the present invention, it is assumed that the fixing rod is formed in a rectangular shape. The holes of the plate are quadrangular corresponding to the size of the rectangular shape of the fixed bar.

 The fixing portion 300 of the laminated structure according to an embodiment of the present invention includes a head 310, a fixing rod 320, a fastening portion 330, and a pressing ring 340.

The head 310 has a hexagonal prism shape. The bottom surface of the head is flat so that the plates come into contact with each other, and a screw groove is formed at the center of the bottom surface so that the first screw portion of the fixing rod can be screwed.

The fixing bar includes a first threaded portion, a body, and a second threaded portion. The body 322 of the fixed bar 320 is formed in a rectangular shape. A first screw portion 321 and a second screw portion 323 are formed on the upper portion and the lower portion of the fixing rod 320 with the body 322 interposed therebetween. The head is coupled to the first screw portion 321 of the fixing rod 320, and the coupling portion 330 is coupled to the second screw portion 323.

The plates of the laminate are sandwiched by the fixing rods 320 and fixed to each other by the head and the fastening portions. Specifically, after the first threaded portion of the fixing rod is screwed to the head, the plates of the laminated body are inserted into the rectangular body of the fixing rod, and then the second threaded portion of the fixing rod is fixed to the hole of the base.

The head is engaged with the first threaded portion of the stationary rod such that the plates are not separated from the stationary rod. The outer diameter of the first threaded portion is formed to be narrower than the diagonal length of the rectangular body. When the first threaded portion of the fixed bar is completely screwed into the threaded groove formed in the bottom surface of the head, the first threaded portion is no longer visible from the outside.

On the other hand, the second threaded portion of the fixing rod is screwed to the fastening portion so that the base closely contacts the plates. The plates can be formed in close contact with each other, thereby improving the accuracy. In the embodiment of the present invention, the fastening portion is formed of a nut, but it may further include a washer provided separately.

The fixing portion of the laminated structure thus configured further includes a position pressing ring 340 for tightly contacting the plates. The pressure ring has a circular shape and has a predetermined thickness. The pressurizing ring is interposed between the lower side of the laminated body and the upper side of the base.

When the laminate is put in close contact with the fixing bar, it is difficult to achieve complete close contact with the plate constituting the laminate. For this purpose, the nut constituting the fastening portion can be rotated and pressed, but the portion to be pressurized is a portion where the base and the stack are in mutual surface contact. That is, the portion to be pressed is widened, the pressing force is lowered, and the plates may not be sufficiently adhered.

The presser ring according to the present invention concentrates the fastening force of the fastening part transmitted from the base. A pressing force is applied to an intermediate portion of the mold around the fixed rod so that the pressing force applied from the locking portion can be stably transmitted to the plate. Here, the intermediate portion of the mold body refers to the position where the area of the outer portion of the mold member divided by the presser ring and the area of the inner portion of the mold member are equally divided.

In order to receive a sufficient fastening force of the fastening portion, it has such a thickness as not to be deformed. Preferably, it should be thicker than the plate constituting the laminate. In Fig. 8, the plate in contact with the pressure ring on the upper side of the pressure ring may be a shape plate or a support plate.

In the present invention, the pressing ring is additionally formed between the laminate and the base (the front surface of the base). However, after the pressing ring is disposed on the back surface of the base, . At this time, the fastening force of the fastening portion can be transmitted to the base through the flat plate to press the laminate.

9 is a view showing the arrangement of the holes of the plate and the head of the stationary part of the present invention.

Referring to the drawings, in the embodiment of the present invention, the same symmetry is formed both from the center of the plate and from the center of the mold. In such a symmetrical structure, the center of gravity can be precisely adjusted by forming one face of the fixed bar having an angle and one face of the plate to have the same plane.

In the present invention, the screw groove length of the head and the length of the threaded portion are designed to be exactly the same so that one side of the square body of the laminate is horizontally the same as the hexagons of the head. From such a configuration, the laminated structure can have a perfect center of gravity at its center.

In Fig. 9, the dotted lines inside the shaped body represent the bottom surface of the head, and L1, L2, and L3 represent lines passing through the outer surfaces of the shaped body, the head, and the holes of the shaped body, respectively. L1, L2 and L3 are all horizontal. In addition, all the lines perpendicular to L1, L2 and L3 pass through the center of the laminate.

10 is a view showing a comparison of the shapes of the fixing rods according to an embodiment of the present invention. FIG. 10A shows coupling to a hole using a circular fixing rod, and FIG. 10B shows coupling to a hole using a rectangular fixing rod.

When a circular fixing rod is used, when the fastening portion is rotated to engage with the fastening portion, the rotating force of the fastening portion is applied to the fixing rod, which causes the constituent elements such as the head and the laminate to twist, It is difficult for the components coupled to the antenna to maintain a constant arrangement.

Alternatively, if a rectangular rod is used, the rotational force of the fastening portion is limited to the rectangular surface and the edge, so that the components coupled to the rod are easily arranged.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the present invention is not limited to the disclosed exemplary embodiments, but various changes and modifications may be made by those skilled in the art without departing from the scope of the present invention.
