In one embodiment of the present invention, it is described as a deck prop 1 used for a deck, but such a post 1 may be used as a post 1 for other purposes in addition to being used for a deck, and its use range There is no limit to.

Referring to Figure 1, it can be seen that the lower end of the step portion 2 is supported by a deck prop 1 according to an embodiment of the present invention.

Deck prop (1) may be installed extending from the lower end of the step portion (2) to the upper top of the step portion (2), in the case of Figure 1, the connection structure between the post and the prop is not shown separately, but Unlike 1, the connection structure between the prop and the prop may be further applied.

The lower end of the deck prop 1 can be fixed by a separate fixing support 3. The fixed support 3 is configured to be fixed to the ground, and serves to support the lower end of the railing paper stock 1 so that the railing paper stock 1 can be stably extended in a direction perpendicular to the ground. The lowermost end of the deck prop 1 can be inserted deeply into the ground by passing through the fixed support 3.

The prop 1 for a deck according to an embodiment of the present invention includes an inner frame 100 serving as a skeleton. In the case of FIG. 1, only the inner frame 100 is installed between the step portion 2 and the fixed support 3. The inner frame 100 is one of the main elements supporting the weight of the staircase 2 or other structures, and the staircase 2 is formed only by the inner frame 100 without a structure such as the connecting frame 200 or the outer frame 300. ).

Main structures of the deck prop 1 according to an embodiment of the present invention will be described with reference to FIGS. 2 to 4.

Deck prop (1) according to an embodiment of the present invention, the inner frame (100) constituting the internal skeleton and supporting the weight of various structures, coupled to the outer surface of the inner frame (100) inner frame (100 ) Is connected to the external frame of the connection frame 200 to protect it from external shocks, and the external frame 300 to protect the connection frame 200 and improve aesthetics.

The inner frame 100 extends in the longitudinal direction and has a hollow tube shape. In the case of an embodiment of the present invention, the inner frame 100 has a rectangular tubular shape, but is not necessarily limited thereto, and may have a polygonal tubular shape.

The inner frame 100 has a hollow cavity 120 inside and may include a piece coupling part (not shown) to which a fixing piece can be coupled. The piece coupling portion may be a hole shape through which the fixing piece may pass, or may be a portion indicating a point through which the fixing piece penetrates. When the fixing piece is in the form of a hole that can penetrate, it is preferable that the hole has a shape smaller than the diameter of the fixing piece.

The connection frame 200 may be made of a metal material or a high-strength plastic material and is fixedly coupled to the outer surface of the inner frame 100. One connecting frame 200 is installed for each outer surface of the inner frame 100, and in the case of one embodiment of the present invention, since the inner frame 100 has a square shape, a total of four connecting frames 200 are each outer surface. Is installed in In summary, depending on the shape of the inner frame 100, the number of connection frames 200 installed may be adjusted.

The connection frame 200 according to an embodiment of the present invention is made of an aluminum material. In addition, the connection frame 200 is installed on each side of the inner frame 100, each connection frame 200 is characterized in that coupled with the neighboring connection frame 200.

Both ends of one of the connection frames 200 may be respectively coupled to neighboring connection frames 200. Specifically, both ends of the connection frame 200 are combined with one end of each of the neighboring connection frames 200, which are different from each other.

In the case of an embodiment of the present invention, the four connection frames 200 installed on each side of the inner frame 100 are all engaged with each other, and as a result, the four connection frames 200, which have been combined, have a square shape. Like the inner frame 100, it has a rectangular tube shape.

For example, if the inner frame 100 has a hexagonal tube shape, a total of six connecting frames 200 will be installed on each side of the inner frame 100.

Each connecting frame 200 covers the entire surface of either side of the inner frame 100. That is, each connection frame 200 has a rectangular shape extending in the height direction as the shape of one side of the inner frame 100. On the premise of this, a detailed configuration of each connection frame 200 will be described. Meanwhile, in the detailed configuration of the connection frame 200 to be described later, the 'longitudinal direction' is defined as a direction leading from the first coupling portion 260 to the second coupling portion 270 based on FIG. 3, and the connection frame Both ends of the 200 mean both ends of the 'longitudinal'. That is, both ends of the connection frame 200 may be interpreted as the first coupling portion 260 and the second coupling portion 270 illustrated in FIG. 3.

Each connection frame 200 forms a body and is formed to protrude on one surface of the plate-shaped body plate 210 and the body plate 210 extending in the longitudinal direction, and the space where the outer frame 300 is seated or installed. One or more first protrusions 220, one or more second protrusions 240 formed to protrude on the other surface of the body plate 210 and provided to be in contact with the outer surface of the inner frame 100, the body plate ( It includes a first coupling portion 260 formed on one end of 210, and a second coupling portion 270 formed on the other end of the body plate (220).

The first protrusion 220 is a configuration that forms a space in which the outer frame 300 is installed or seated. The first protrusion 220 may be formed to protrude one or more on one surface of the body plate 210.

In the exemplary embodiment of the present invention, two first protrusions 220 are formed on one surface of the body plate 210. In addition, each first protrusion 220 is continuously projected along the height direction of the body plate 210 and is provided one at a suitable position along the length direction.

The second protrusion 240 is configured to directly contact the inner frame 100, and one or more protrusions are formed on the other surface of the body plate 210.

In an embodiment of the present invention, two second protrusions 240 are formed on the other surface of the body plate 210. It is preferable that two or more second protrusions 240 are provided so that the connection frame 200 can be stably coupled and supported to the surface of the inner frame 100.

The second protrusion 240 is composed of a second protrusion front surface 242 that directly contacts the inner frame 100 and a second protrusion side 241 that forms a side surface of the second protrusion 240.

The second protruding front surface 242 may be in contact with the inner frame 100 after protrusions are formed on the surface to be fixedly coupled to the inner frame 100 or after adhesive or the like is applied to the second protruding front surface 242.

Meanwhile, each connection frame 200 includes a first space 230 formed by two or more first protrusions 220 and a body plate 210, two or more second protrusions 240 and a body plate 210. A second space 250 formed by, and a third space formed between the second protrusion 240 and the first coupling part 260 and between the second protrusion 240 and the second coupling part 270, respectively 280.

The first space 230 is a space where the intermediate frame 310 constituting the outer frame 300 is seated and / or combined.

The second space 250 provides a space through which the fixing piece passing through the inner frame 100 can penetrate the body plate 210. The third space 280 also provides a space through which the fixing piece passing through the inner frame 100 can penetrate the body plate 210.

The body plate 210 portion between the second space 250 and the first space 230 and the body plate 210 portion directly contacting the third space 280 include a first protrusion 220 and a second protrusion ( 240) is thinner than the body plate 210 portion directly contacting. Due to this feature, the fixing frame for connecting the inner frame 100, the connecting frame 200, and the outer frame 300 can easily penetrate the body plate 210 of the corresponding part, so that the prop for the deck 1 ) Has the effect of easy production.

In the case of a conventional body plate, one entire surface directly contacts the inner frame without a separate protrusion. However, since both the inner frame and the connecting frame have large lengths and widths in the height direction and the length direction, there are many cases in which bending or warping occurs due to minute tolerances. Even if such a very small tolerance banding or warping occurs, it is difficult to completely contact one side of the inner frame and one side of the connecting frame, because both the inner frame and the connecting frame have large sizes. Even if the two components are forcibly fixed in contact with each other, after a period of time, the degree of warping becomes more severe, resulting in a problem that the durability of the entire prop is reduced. In addition, since the thickness of the connecting frame is evenly thick, it is difficult to penetrate the fixing piece.

The second protrusion 240 is a configuration capable of solving these problems. When at least two second protrusions 240 are provided according to an embodiment of the present invention, since the contact area between the inner frame 100 and the connecting frame 200 is reduced, stable contact between the two configurations is maintained. I can do it. In addition, by allowing the fixing piece to be easily penetrated through the spaces in which the second protrusions 240 or the first protrusions 220 are not formed, an effect of increasing the efficiency of production is generated.

Meanwhile, the thickness t1 of the body plate 210 formed between the first space 230 and the second space 250 according to an embodiment of the present invention is the body plate 210 contacting the third space 280. ) Is characterized by being thinner than the thickness t2.

Due to the structural features of the first coupling portion 260 and the second coupling portion 270, which will be described later, the plurality of connection frames 200 are formed into a single tube by combining one end with the other end of a neighboring connection frame. Will achieve. In order for these interlocking connection frames 200 to be finally combined as a tube shape, the connection frame 200 itself must be capable of some bending.

The connecting frame 200 should be hard to protect the inner frame 100 from external impact, but in order to cover the outer surface of the inner frame 100 with a plurality of connecting frames 200, the connecting frame 200 can be bent to some extent. Needs to be constructed.

The thinner the banding, the easier it is. In addition, the thinner the center is, the better, in order to maximize the bending of an object. Therefore, it is preferable that the thickness of the center is thinner than the thickness of the edge of the connection frame 200 in order to maximize the bending of the connection frame 200 according to an embodiment of the present invention.

The first coupling portion 260 of the connection frame 200 is coupled to the second coupling portion 270 of the neighboring connection frame, and the second coupling portion 270 of the connection frame 200 is another neighboring connection frame It is coupled to the first coupling portion 260.

Specifically, the first coupling portion 260 includes an insertion portion 261 provided to be inserted into the second coupling portion 270 and a support portion 262 provided to be supported on the second coupling portion 270. .

The second coupling part 270 includes a coupling support part 272 provided to be in contact with the support part 262, an inner support part 273 provided to support one surface of the insertion part 261, and a coupling support part 272 And a seating portion 271 formed between the inner supporting portion 273 and providing a space into which the inserting portion 261 can be inserted.

The insertion portion 261 has a shape that protrudes a predetermined distance more than the support portion 262 in one direction of the body plate 210, and the support portion 262 is closer to one surface of the body plate 210 than the insertion portion 261. Is located on the side.

Coupling support 272 is located at the other end of the body plate 210, the inner support 273 is formed at a position spaced apart in one direction of the body plate 210 a predetermined distance than the coupling support 272. The distance between the engaging support 272 and the inner support 273 and the width of the insert 261 are approximately similar.

The seating portion 271 formed by the coupling support portion 272, the inner support portion 273, and the body plate 210 provides a space in which the insertion portion 261 can be seated, and the open surface of the seating portion 271 It is characterized in that the direction of is not parallel to the extending direction of the insertion portion 261 (the projecting direction).

In the exemplary embodiment of the present invention, since the inner frame 100 has a rectangular pipe shape, the direction of the seating portion 271 opening surface and the direction of the insertion portion 261 extending approximately 90 degrees.

If the inner frame 100 has a hexagonal pipe shape, the direction of the seating portion 271 opening surface and the direction of extension of the insertion portion 261 form approximately 120 degrees.

The outer frame 300 may be made of various materials for wood or deco. In an embodiment of the present invention, the outer frame 300 is made of wood and consists of a number of pieces. Specifically, when two first projections 220 are provided for each connection frame 200, the outer frame 300 may be composed of one intermediate frame 310 and two outer frames 320.

The intermediate frame 310 is seated between two first protrusions 220. The two outer frames 320 are respectively seated on the outer side of the first protrusion 220. As illustrated in FIG. 3, the outer frame 320 installed in one of the connection frames 200 is in contact with the outer frame 320 installed in the neighboring connection frames 200. At this time, an adhesive may be applied to a portion where the outer frames 320 are in contact with each other, or a separate bonding structure may be further included.

When all of the inner frame 100, the plurality of connecting frames 200 and the outer frame 300 are combined, the fixing piece is connected from the inner cavity 120 of the inner frame 100 to the connecting frame 200 and the outer frame 300 ), The three components can be fixed.

5 to 9 will be described with reference to various embodiments that can increase the coupling force between the components.

5 shows an embodiment in which the protruding member 261a is formed on the side surface of the insertion portion 261. The protruding member 261a may protrude in the direction of the support portion 262 or protrude in the opposite direction of the support portion 262.

Through the protruding protrusion member 261a, the insertion portion 261 is forcibly fitted into the seating portion 271, thereby increasing the coupling force between the connection frames 200.

Meanwhile, a groove (not shown) corresponding to the protruding member 261a may be further provided on the side surface of the coupling support portion 272 or the side surface of the inner support portion 273. Through the protrusion member 261a and the groove structure, the coupling force between the connection frame 200 is further increased, which serves to increase the durability of the deck prop 1.

The reason this structure is possible is that the connection frame 200 is made of a metal material (such as aluminum) having a predetermined elasticity.

6 shows an embodiment in which the inner surface of the engaging support portion 272 is made of an inclined portion 272a. The inclined portion 272a is characterized in that the width of the seating portion 271 is inclined in an increasingly narrow direction toward the open surface.

The inclined portion 272a applies an elastic force to the inserting portion 261 so that the inserting portion 261 inserted into the seating portion 271 through the inclined portion 272a is not easily separated.

The inclined portion 272a may be formed on the inner surface of the inner support portion 273 as well as the inner surface of the engaging support portion 272, and may be formed on both inner sides of both configurations.

Meanwhile, the embodiment of FIG. 5 and the embodiment of FIG. 6 may be selectively combined. For example, when both the protruding member 261a of FIG. 5 and the inclined portion 272a of FIG. 6 are applied to the connection frame 200, it is possible to obtain an effect that the coupling force between the connection frames 200 is further improved.

7 corresponds to an embodiment in which the coupling force can be increased when the outer frame 300 is coupled between the first protrusions 220.

The first protruding part 220 includes a first protruding part front surface 222 and a first protruding part side 221 corresponding to the side surfaces of the first protruding part 220. In the case of FIG. 7, an embodiment in which the first protrusion side 221 is formed of an inclined surface 221a inclined at a predetermined angle is illustrated.

Specifically, the inclined surface 221a is formed with an inclination in a direction in which the cross section of the first protruding portion 220 becomes larger as it moves away from the body plate 210. Due to these structural features, the distance between the first protrusion 220 and the first protrusion 220 is characterized by being smaller than the width of the intermediate frame 310, and the intermediate frame 310 is located in the first space 230. You will be forced to join.

When the intermediate frame 310 is forcedly coupled to the first space 230, the intermediate frame 310 is prevented from moving within the first space 230 when passing through the fixed piece, so that the fixed piece can be easily penetrated. The effect can be made.

7, the inclined surface 221a may be formed only on one side surface of each of the first protruding parts 220 as shown in FIG. 7, but may also be formed on all the first protruding part side surfaces 221.

The inclined surface (221a) is not only the intermediate frame 310, but also allows the outer frame 320 to be fitted. Meanwhile, the intermediate frame 310 and the outer frame 320 may be partially processed to fit the inclined surface 221a.

The embodiment of FIG. 7 can also be selectively combined with the embodiments of FIGS. 5 to 6.

FIG. 8 shows that the first protruding side 221 is formed as a protruding surface 221b unlike the inclined surface 221a of FIG. 7.

The protruding surface 221b corresponds to a linear protrusion that protrudes finely on the surface of the first protruding side 221, and like the inclined surface 221a, the intermediate frame 310 and the outer frame 320 are connected to the connecting frame 200. This is a configuration that induces a coercive fit.

8, the protruding surface 221b may be formed only on a portion of the first protruding side 221 and may be formed on the entire surface of the first protruding side 221.

The protruding surface 221b may be formed of the same aluminum material as the first protrusion 220 or may be made of a material having a high frictional force. When formed of a material having a high frictional force, the protruding surface 221b may be formed on the first protruding side 221 through post-processing of the connection frame 200 after processing.

Meanwhile, the inclined surface 221a of FIG. 7 and the protruding surface 221b of FIG. 8 may be simultaneously applied to the first protruding side 221. By applying both the inclined surface 221a and the protruding surface 221b, there is an effect of improving the bonding force between the outer frame 300 and the connecting frame 200.

9 shows a coupling protrusion 211 formed on one surface of the body plate 210.

The coupling protrusion 211 is a component that is inserted into one surface of the outer frame 300 when the outer frame 300 is combined with the connecting frame 200. The end of the coupling protrusion 211 is sharply formed, and one side may be provided with an inclined shape.

The coupling protrusion 211 may be formed over the entire surface of the body plate 210. However, when the coupling protrusion 211 is formed in a space other than the first space 230, it is preferably formed to have an inclined surface as shown in FIG. In the case of the outer frame 320, unlike the intermediate frame 310, only one first protrusion 220 is contacted. Therefore, it can be easily separated in a direction away from the adjacent first protrusion 220.

At this time, as shown in FIG. 9, the surface where the coupling protrusion 211 is adjacent to the adjacent first protrusion 220 has an inclined surface of 90 degrees from the body plate 210 or is inclined to be inclined in the direction of the first protrusion 220. If the inclination is inclined to incline in the direction of the first protruding portion 220, the surface far from the protruding portion 220 has an effect of reducing the phenomenon that the outer frame 320 is separated from the connecting frame 200.

5 to 9 can be selectively and plurally applied to the deck prop (1).
