Rather, it is about an expandable interior shelf that can be used as shelf furniture that creates decorativeness and luxury.

In general, a prefabricated shelf refers to an angle of metal that is bent in a "b" shape, vertically, and then these vertical angles are also connected in a horizontal direction using an angle of a "b" shape. It is made by placing a square plate on the wall, and it is used by assembling shelves of various sizes and multiple stages.

Such prefabricated shelves are easy to assemble and disassemble and are relatively inexpensive and are widely used for loading or storing various items or materials.

In addition, in recent years, the fastening structure and assembly structure for the prefabricated shelf as described above are being improved to have more excellent efficiency. As shown in Utility Model Registration No. 20-0473407, the horizontal frame and the vertical frame are connected in various directions. In the prefabricated angle shelf that assembles to form a shelf, the assembling part is rigid and the assembled state is not easily shaken. The assembling part of the horizontal frame and the vertical frame is simple, so that even general users without specialized knowledge can easily assemble it. An assembly type angle shelf with a new assembly method that can be disassembled and used in various ways to suit the installation environment has been devised and registered.

Subsequently, as in Patent No. 10-1514350, a vertical member consisting of two bent portions bent at right angles and having a plurality of binding bars protruding inward by press processing at equal intervals inside each bent portion, and two In order to connect the vertical member horizontally, an opening hole having a width greater than the width of the binding rod of the vertical member is formed at the connection portion with connection portions at both ends, and inserted into the binding rod of the vertical member at the upper side of the opening hole. And a horizontal member having a first connection tab and a second connection tab aligned with the first connection tab formed below the connection part, and the first connection of the connection part when connecting the horizontal member to the vertical member An angle shelf in which a tab and the second connection tab are inserted into the upper and lower two binding tables formed on the bent portion of the vertical member has been devised and registered.

In addition, as in Patent No. 10-1576506, a plurality of posts that are erected and arranged in a front, rear, and left and right rectangles and having a plurality of hook holes; A shelf hanger coupled to the hanger hole of the post to form a support frame for storing articles together with the post; It is supported by the shelf hanger and is arranged in a plurality along the vertical direction, and includes a shelf forming a multi-stage loading portion for placing and supporting an article on the support frame, and the post is a pair of parallel to each other at both ends of the connecting support post It is composed of a bar-shaped supporting post piece, so that the posts arranged in the front and rear positions are supported while the posts are erected in the longitudinal direction in the front and rear positions and the left and right positions. The post pieces are arranged to face each other, and the hanger pieces of the shelf hanger extend in a direction crossing the length direction at both ends of the front left and right posts and the rear left and right posts in the hook holes of the support post pieces facing each other. The shelf hanger is fitted so as to be arranged in parallel with the front and rear directions of the support frame, and the shelf is mounted on the shelf hanger connected to the front end and the rear end of the post.

Subsequently, in an angle shelf frame consisting of a vertical support in which a plurality of coupling holes are vertically arranged in an angle shape as in Korean Patent Application Publication No. 10-2018-0131781, and a horizontal support inserted and guided and fixed in the coupling hole of the vertical support, As the horizontal support is formed integrally with an upper fixing plate and a lower fixing plate having fasteners inserted into the coupling holes, and a support bent portion bent between the upper fixing plate and the lower fixing plate to place the shelf on the horizontal support, An angle shelf frame that has the effect of preventing the shelves and objects from falling due to the load of the shelves and the storage objects on which they are seated, and preventing the objects from falling due to shaking caused by external shocks is constructed and It has been registered.

However, the prefabricated shelf including the conventional angle shelf is not utilized as an indoor shelf furniture because the shelf frame, that is, the repetitive fastening hole formed on the angle is exposed to the outside as it is, so it lacks decoration and is not good in terms of aesthetics. In order to fasten and assemble these angles or frames, there is a problem in that assembly and manufacturing convenience are extremely poor, such as having to use a separate tool.

In addition, in order to prevent the above fastening hole from being exposed to the outer surface, a separate cover may be used or it may be manufactured in the form of an extruded steel that is formed only on the inner surface. It is not easy to handle and assembles, as well as weakening the fixing force between each other, it has a disadvantage that does not satisfy the function as a shelf.

In addition, the existing prefabricated shelf can only be manufactured as a single unit in a square shape on the plane.Since it does not have any expandability in all directions using vertical angles or vertical posts, the prefabricated shelf of several objects is manufactured separately. These prefabricated shelves have to be installed in a row or connected and fixed through separate fastening means, which is extremely unreasonable in terms of expandability.

It has to be able to be easily inserted into the connecting slit (11) (11'), and the upper and lower widths of the horizontal support (23) (23') are The horizontal support part 23, 23' in the state inserted into the connecting slit 11, 11' is not necessary in the connecting slit 11, 11' because it is made in a shape that is the same as the upper and lower widths or slightly smaller. It would be ideal to avoid excessive upward and downward flow.

In addition, the fixing lever 30 is integrally formed with a handle portion 33 in the shape of a "b" downward from the rotation shaft part 31 of the tip, and the shaft on both sides of the rotation shaft part 31 A protrusion (not shown in the drawing) is inserted through the horizontal support portions 23 and 23 ′ of the fastening bracket 20 and rotated by the shaft protrusion, and an eccentricity at one side of the rotation shaft portion 31 The pressing portion 32 is protruding.

At this time, the eccentric pressing part 32 should be formed at a position in which the eccentric pressing part 32 faces the vertical tube 10, 10' while the handle part 33 is horizontal, and the handle The upper surface of the part 33 is formed with a locking protrusion 34 protruding upward, and the eccentric pressing part 32 is fixed by firmly engaging the vertical pipes 10 and 10 ′ and the connection fastener 50 The locking protrusion 34 serves to prevent the handle portion 33 rotated in the fastening direction from being rotated downward by shock or vibration.

Subsequently, the connection fastener 50 coupled to the end of the horizontal tube 40 and 40 ′ has a receiving groove 51 into which one side of the fastening bracket 20 is inserted in a downwardly open form. , The front side of the receiving groove 51 is formed with a vertical tube (10) (10 ′) with a close contact fixing piece (52) is formed, and the both sides of the contact fixing piece (52) is horizontal on both sides of the fastening bracket (20) One fitting groove 53 and 53 ′ is formed so that the support 23 and 23 ′ can be inserted.

In addition, repeated interference protrusions 54 and 54 ′ are formed on the outer surface of the connection fixing tool 50, and one end of the connection fixing tool 50 has the horizontal pipe body 40, 40 ′. The locking projection 55 having the same outer periphery is protruding, and when the connection fixing member 50 is inserted into the end of the horizontal tube 40, 40', the locking projection 55 causes interference. A rigid coupling and fixing in the form of force-fitting is made, and the locking projection 55 serves to prevent the connection fixing device 50 from being unnecessarily inserted deep into the interior of the horizontal pipes 40 and 40 ′.

In particular, a cut-out groove 41 is formed so that the receiving groove 51 of the connection fixing device 50 is exposed below the ends of the horizontal pipe bodies 40 and 40 ′ as described above, and the horizontal pipe body When the connection fixing tool 50 is inserted and fixed at the end of 40 (40'), the receiving groove 51 of the connection fixing tool 50 is exposed through the cutout groove 41 of the horizontal pipe body 40, 40' It will be, and can be coupled and fixed to the fastening bracket 20 using the receiving groove 51.

Thus, to explain in detail the assembly process of the present invention expandable interior shelf using the vertical pipe body 10 (10'), the fastening bracket 20, the fixing lever 30, and the horizontal pipe body 40, 40' as described above. do.

First, as shown in FIG. 7, the fixing lever 30 is coupled to the connection slit 11 and 11 ′ having a desired height among the connecting slit 11 and 11 ′ of the vertical pipe 10 and 10 ′. It is coupled by inserting the fastening bracket 20 in the state.

That is, a state inclined slightly upward so that the locking support portions 21, 21' and the horizontal support portions 23, 23' of the fastening bracket 20 can be inserted into the connection slit 11, 11'. After being inserted into the horizontal support portion 23, 23', the fastening bracket 20 is lowered so that the lower thickness portion of the connecting slit 11, 11' can be inserted into the locking groove 25 of the horizontal support portion 23, 23'. As the thickness of the vertical tube 10 and 10 ′ is inserted into the locking groove 25, temporary fixing to the fastening bracket 20 is performed, and at the same time, the locking support 21 and 21 ′ The protrusion 24 is in contact with the inner surface of the vertical pipes 10 and 10'.

In this state, the fixing lever 30 is naturally rotated downward by its own weight of the handle part 33, and the eccentric pressing part 32 of the rotation shaft part 31 is directed upward.

Subsequently, when the horizontal pipes 40 and 40 ′ in a state in which the connection fasteners 50 are coupled to the ends are coupled downward in the direction shown in FIG. 8, the reception of the connection fasteners 50 as shown in FIG. 9 One side of the fastening bracket 20 is inserted into the groove 51, and the close contact fixing piece 52 of the connection fastener 50 is inserted and positioned in front of the rotation shaft 31 of the fixing lever 30.

In addition, when the handle portion 33 of the fixing lever 30 rotated downward in the temporary assembly state as described above is rotated upward, the eccentric pressing portion 32 is vertically rotated from the upper side due to the rotation of the rotation shaft portion 31. (10) It will be rotated in the direction toward (10'), and the eccentric pressing unit 32, which is in a deflected protrusion during the rotation of the eccentric pressing unit 32, presses the inner surface of the contact fixing piece 52. It becomes.

Therefore, one surface of the locking protrusion 24 and the locking groove 25 of the fastening bracket 20 is locked to the inner surface of the vertical tube 10, 10 ′ to produce a strong supporting force, and the fixing lever 30 The eccentric pressurizing part 32 of the vertical tube 10, 10' of the connection fixture 50, which is located on the outer surface of the contact fixing piece 52 of the connection fixing device 50 is strongly pushed, so in the end, the locking support parts 21, 21 ') and the eccentric pressing unit 32, the thickness portion of the vertical tube 10, 10' and the contact fixing piece 52 are in close contact with each other, thereby creating a firm contact fixing state between them.

Thus, after assembling the connection fixture 50 of the horizontal pipe body 40, 40' to the fastening bracket 20 coupled to the connection slit 11, 11' of the vertical pipe body 10, 10', When the fixing lever 30 coupled to the fastening bracket 20 is rotated, the connection fixing device 50 is strongly adhered to and fixed toward the outer surface of the vertical pipe body 10, 10', so that the vertical pipe body 10 )(10') and the horizontal pipe body 40,40', a strong fixed state is produced, and at the same time, the connection fixing tool 50 between the outer surface of the vertical pipe body 10,10' and the horizontal pipe body 40,40' There is no gap between the outer surfaces and a tight, tight bond can be achieved.

In addition, when the handle portion 33 as described above is further rotated toward the bottom of the horizontal pipe body 40, 40', the locking protrusion 34 formed on the handle portion 33 becomes the fastening bracket 20 ) While being inserted between the connection support portion 22 and the inner surface of the receiving groove 51 of the connection fixture 50, the outer surface of the connection support 22 or the inner surface of the receiving groove 51 Due to the interference resistance against the locking protrusion 34, the handle portion 33 can be prevented from rotating downward from shock or vibration.

In addition, the interior shelf of the present invention consists of a rectangular vertical tube 10, 10' and a horizontal tube 40, 40', as well as the vertical tube 10, 10' for connecting each tube. Since the connecting slit (11) (11') is not exposed to the outside at all, the appearance of the shelf is very beautiful, and the interconnection part of each tube is not exposed at all, so it can be used as shelf furniture for interior decoration, as in the past. In addition to being used for loading materials, it can fulfill its role as display, exhibition and storage furniture.

Moreover, the interior shelf of the present invention has expandability in various directions as necessary, and the connecting slits 11 and 11 ′ formed on the vertical pipes 10 and 10 ′ are formed on the four sides of the square tube. It can produce excellent expandability by forming it in various ways on the construction surface in the desired direction.

That is, in the case of forming the connecting slits 11 and 11 ′ on two surfaces of the vertical pipes 10 and 10 ′ arranged at right angles as shown in FIG. 12, the horizontal pipes 40 and 40 ( 40') can be fixed, and when connecting slits (11) (11') are formed on three of the four sides of the vertical pipe (10) (10') for expansion in one direction, three sides It is possible to connect and fix the horizontal pipes 40 and 40 ′ having an expansion shape in one direction by using the vertical pipes 10 and 10 ′ of the connection slit 11 and 11 ′.

In addition, when expansion to both sides is necessary, the horizontal pipes 40 and 40 ′ are connected in all directions by forming the connecting slits 11 and 11 ′ on all four surfaces of the vertical pipes 10 and 10 ′. Therefore, it is possible to infinitely expand in any direction desired through the application of replacement to the vertical pipes 10 and 10 ′, and the vertical pipe 10 located on the outermost side even if the expansion to the shelf is made Since the connecting slits 11 and 11' are still not exposed on the surface of (10'), it can be sufficiently utilized as interior furniture.

In particular, since the height of the shelf panel before expansion and the height of the shelf panel at the expansion position can be formed equally when connecting the expansion as described above, the entire shelf panel can be assembled to match the height regardless of whether or not it is expanded, so the convenience of use is improved. Of course, it is also very good in terms of various uses.

The configurations shown in the embodiments and drawings as described above are only the most preferred embodiment of the present invention, and do not represent all the technical spirit of the present invention, so various equivalents and modifications that can replace them It should be understood that there may be examples.
