In addition, it is also possible to install the shelf height adjustment structure according to the present invention in one place and use the small shelf.

The strut 30 is a member in the form of a long rod as a vertical frame, as partially shown in FIGS. 2 to 4. The longitudinal direction of the support 30 is the height direction of the shelf. The support 30 has guide rail grooves 32 formed on both side surfaces thereof in the longitudinal direction thereof. Further, a plurality of fixing grooves 34 are formed at regular intervals along the longitudinal direction. The fixing groove 34 is shown as a circular opening, but only if the shape corresponds to the cross section of the projection 44 of the bracket 40 to be inserted into the fixing groove 34. Thus, the fixing groove 34 is not necessarily limited to the circular shape, it is possible to be formed in a square or various other shapes according to the decorative needs or other needs.

In addition, if the guide rail groove 32 and the fixing groove 34 is formed corresponding to the fixing rail 42 and the protrusion 44 of the bracket 40, the present invention is limited to the example shown in FIG. It is not. For example, the guide rail groove 32 and the fixed groove 34 may be injection molded integrally with the aluminum frame.

As shown in FIG. 4, a structure for protecting the portion in which the protrusion 44 of the bracket 40 is inserted into the fixing groove 34 of the support 30 from the external environment may be provided. That is, the support 30 protrudes from the rear surface of the fixing groove 34 in a form that defines the insertion space portion 36 extending and received when the protrusion 44 of the bracket 40 is inserted into the fixing groove 34. It can have a finished structure.

As in the example shown in FIG. 4, the support 30 has guide rail grooves 32 formed at both sides thereof, and the main support member 30a and the fixed groove 34 protruded to form the insertion space portion 36 at the rear surface thereof. ) May be formed of the auxiliary strut member 30b. In this example, the cross section of the support 30 is generally rectangular in shape, but the present invention need not be limited to this cross-sectional shape. Since the support 30 has a fixing groove 34 and a guide rail groove 32, it is sufficient to have various cross-sections such as round cross-sectional shapes partially rounded according to the needs of the furniture or product to be applied or according to aesthetic or decorative needs. Those skilled in the art will readily understand that shapes are possible.

Bracket 40 has a body 49 for acting as a pedestal for mounting the shelf is coupled to the support 30 as shown in Figures 2 and 3. The body 49 may be any shape as long as it can put a shelf on the top.

In addition, the bracket 40 has a fixed rail portion 42 and a protrusion 44 as a structure coupled to the support 30, as shown in detail in FIGS. And an elastic assembly 48 which is a mechanical link portion for moving the protrusion 44 by operating the switch 46 and the switch 46 for operating the protrusion 44.

The fixed rail part 42 is a part that can be slidably coupled to the guide rail groove 32 of the support 30 at one side of the body 49. The fixed rail unit 42 may be formed by the front plate 41 and the rail plate 43 as shown in the example, but various forms may be possible in addition to the illustrated form. In the illustrated example, the fixed rail portion 42 is coupled to the inside of both guide rail grooves 32, but the present invention need not be limited thereto. That is, as is well known in the art of sliding coupling structure of the rail form, it is also possible that the fixed rail 42 is coupled to the outside of both guide rail groove (32).

The projection 44 is protruded out of the fixed rail portion 42 at the center of the fixed rail portion 42 at ordinary times, and is elastically fixed only while applying pressure to the switch 46 formed in the body 49. It is characterized in that it is introduced into the body 49 without protruding from the surface of the rail portion 42.

The protruding and introducing movement of the protrusion 44 is made by a switch 46 operated by a user. The switch 46 and the protrusion 44 are connected to the elastic assembly 48 installed in the body 49.

In the preferred embodiment, the switch 46 may be in the form that the user presses to move the position by a predetermined interval. In the illustrated example, the switch 46 is in the form of a protrusion that can be pulled by a user, for example, a finger, but may be formed so as not to harm the aesthetics by being embedded in the surface of the body 49 in a flat rectangular shape, for example.

The elastic assembly 48 is configured to pull the protrusion 44 into the body 49 by a corresponding distance when the switch 46 is moved by a predetermined distance as in the example shown in FIG. 6. When the protrusion 44 is pulled into the body 49, for example, it is an elastic spring or a structure in which elastic force is accumulated in an elastic member having a shock absorber (hereinafter, referred to as a "shock absorber") structure.
