At this time, while the elastic member 540 is compressed to the maximum, the tightening bundle 500 excessively approaches toward the inner surfaces of the first and second frames 110 and 120, and the inner surfaces of the first and second frames 110 and 120 damage can be prevented. In addition, since the elastic member 540 is compressed to the maximum, the force is applied to the tightening bundle 500 in the opposite inner surface direction to prevent the left and right movement of the tightening bundle 500, so that between the connecting portion 530 and the first screw body 612 It is possible to prevent loosening of screw connections.

Since the first and second pressing ends 511 and 521 are formed at the ends of the thin plate-like material, there is a gap between the first and second pressing ends 511 and 521 and the inner surfaces of the first and second frames 110 and 120. pressure can be maximized.

In one embodiment of the present invention, two pressing parts 510 and 520 are formed, and the two pressing parts 510 and 520 press the first and second frames 110 and 120 one by one, but it is not limited thereto. don't For example, more than two pressing parts (not shown) extending from the connection part 530 may be formed in the tightening bundle 500, and in this case, the joint body 400 has penetrations corresponding to the number and position of the pressing parts. A ball (not shown) may be formed.

Conversely, when the user turns the first screw head 611 exposed to the outside of each of the first and second frames 110 and 120 in the loosening direction, the tightening bundle 500 is the first and second frames ( 110 and 120, while moving in the opposite direction of the inner surface, that is, in the direction away from the first screw head 611, the fixing force is released. The user may lift and remove the second frame 120, collect the joint module 20, and reuse only the first frame 110.

According to this, the first and second frames are only operated by inserting the joint module 20 into each of the plurality of first frames 110, placing the second frame 120 thereon, and then turning the first tightening screw 610. (110, 120) can be fixed quickly and firmly.

Accordingly, there is no need to separately fasten bolts to expand the structure of the shelf 1, thereby reducing assembly time.

In addition, since the joint module 20 according to an embodiment of the present invention has a shape inserted into the first and second frames 110 and 120, the first tightening screw ( 610) does not need to be drilled at predetermined lengths, so the appearance of the shelf 1 is good, and durability is preserved because the joint module 20 does not support the load of the second frame 120, for example. It can be.

Referring to FIG. 6 , the first tightening screw 610 may pass through a through hole (not marked) at a portion where the first frame 110 and the second frame 120 come into contact. That is, the first frame 110 is provided with a semicircular groove 111 formed toward the top at the top and the second frame 120 is provided with a semicircular groove 121 formed toward the bottom at the bottom, the first frame 110 When the ) and the second frame 120 are disposed in the longitudinal direction and come into contact, the semicircular groove 111 and the semicircular groove 112 come into contact to form a through hole. Through-holes may be formed in common at upper and lower ends of all frames constituting the shelf 1 .

The diameter of the through hole may be substantially equal to or slightly larger than the diameter of the neck of the first screw head 611 . Therefore, as shown in FIGS. 6 and 7 , in a state where the frames 110 and 120 in which the joint bodies 400 are arranged in series are accommodated inside, the first screw head 611 extends to the outside of the frame module 100. can be exposed as At this time, the first screw body 612 of the first tightening screw 610 may pass through the through hole and span the inside and outside of the first and second frames 110 and 120 .

The through hole is preferably formed in the frame module 100 so that the shelf 1 can be brought into close contact with a structure such as a wall as much as possible so that the first screw head 611 does not protrude outside the shelf 1. . However, the position of the through hole where the first tightening screw 610 is disposed is not limited thereto, and the direction of the through hole may be any one of the side surfaces of the first and second frames 110 and 120. For example, the direction of the through hole may be formed in the width direction of the shelf 1 .

To extend the shelf 1 in the vertical direction, the user first inserts one joint module 20 into each of the openings at the top of the four first frames 110 supported on the floor. At this time, since the first screw head 611 of the joint module 20 spans the semicircular groove 112 at the top, the joint module 20 does not fall inside the first frame 110 and the joint body 400 Half of may protrude to the top of the first frame (110).

Next, place the four second frames 120 on the upper side of the four first frames 110 and insert the protruding parts of the joint module 20 into the openings of the lower ends of the four second frames 120. let it Accordingly, the upper end of the first frame 110 and the lower end of the second frame 120 may be connected in series at four locations.

The regulation piece 700 has one side connected from the tightening bundle 500 and the other side facing away from the first and second pressing parts 510 and 520 of the tightening bundle 500, that is, the surface on which the fourth through hole 450 is formed. can be extended towards The regulating piece 700 may have a plate shape having the same height or length as the connection part 530 and may extend from the first screw body 612 . The regulation piece 700 may be positioned between the first screw body 612 and the joint body 710 .

The regulation piece 700 is supported inside the joint body 400 even when the first tightening screw 610 rotates in one direction to prevent rotation of the tightening bundle 500, and even if the tightening screw 600 is removed, the tightening bundle (500) may have a length in the left and right direction to prevent separation from the joint body (400).

When the user holds the first screw head 611 and rotates it in a tightening direction (eg, clockwise), the first screw body 612 rotates in the tightening direction. At this time, since the regulating piece 700 is in close contact with the inner surface of the joint body 400 over the area, rotation of the tightening bundle 500 together with the first screw body 612 is restricted. Therefore, the tightening bundle 500 can be linearly moved along the first screw body 612 by a screwing relationship with the connecting portion 530.

When the first tightening screw 610 rotates in the tightening direction, the first pressing portion 510 of the tightening bundle 500 penetrates the first through hole 420 and the second pressing portion 520 passes through the second through hole. Threads (not shown) are provided in the first and second through-holes 420 and 430 so that the first and second pressing parts 510 and 520 linearly move in the direction of exiting the joint body 400 while penetrating the 430. ) may be pre-determined and formed.

Conversely, when the user holds the first screw head 611 and rotates it in a loosening direction opposite to the tightening direction (eg, counterclockwise), the first screw body 612 rotates in the loosening direction, and the tightening bundle ( The first and second pressing parts 510 and 520 of 500) may linearly move in a direction away from the first and second through holes 420 and 430, that is, in a direction entering the inside of the joint body 710.

In the above unwinding process, when the tightening bundle 500 moves toward the inner surface where the fourth through hole 450 of the joint body 400 is formed as much as possible, the end of the regulation piece 700 touches the corresponding inner surface and tightens the tightening bundle. Movement of 500 may be limited.

In addition, the regulation piece 700 is the first and second pressing parts (even if the tightening bundle 500 is moved to the loosening position as much as possible, that is, toward the inner surface where the fourth through hole 450 of the joint body 400 is formed) Ends of the first and second through holes 510 and 520 may be formed with left and right lengths so that they do not completely come out of the first and second through holes 420 and 430 . Referring to (a) of Figure 5, the length from one end to the other end of either the first pressing portion 510 or the second pressing portion 520 of the tightening bundle 500 when viewed in plan view is 'a', When the length from one end to the other end of the regulation piece 700 is formed in 'b' and 'c' characters, and the distance between both ends of the tightening bundle 500 bent so that both ends face each other is 'c', 'a' + b ≥ c' can be satisfied.

Therefore, the user excessively turns the first tightening screw 610 in the loosening direction so that the first and second pressing parts 510 and 520 separate from the first and second through holes 420 and 430, respectively, and the tightening bundle ( 500) by its own weight, the tightening bundle 500 droops downward to prevent the first and second pressing parts 510 and 520 from being displaced from the first and second through holes 420 and 430.

In this way, the joint module 20 may fix and support the serial connection of the vertically disposed first frame 110 and the second frame 120 .

As shown in FIG. 7, since the joint body 400 of the joint module 20 is disposed in close contact with the inner surfaces of the first and second frames 110 and 120, the first and second frames 110, 120), even if a horizontal force is applied to the side, the upper second frame 120 is not pushed to the side to prevent separation.

An anti-slip means 621a formed of irregularities may be provided on the outer surface of the second screw head 621 .

The second screw body 622 may pass through the fourth through hole 450 of the joint body 400 . In addition, the second screw body 622 may pass through through-holes (unsigned) made of the semicircular grooves 111 and 112 of the first and second frames 110 and 120 . At this time, the second screw body 622 may pass through a through hole provided on the opposite side of the through hole through which the first screw body 612 passes.

The second screw body 622 may have one end extending from the second screw head 621 and the other end open to form a hollow 623 inside. A second screw thread 624 corresponding to the first screw thread 613 may be formed on the inner surface of the second screw body 622 in which the hollow 623 is formed.

Accordingly, the first screw body 612 is inserted into the second screw body 622 so that the first screw thread 613 and the second screw thread 624 are engaged with each other. At this time, the user grasps the first screw head 611 and the second screw head 621 with both hands and rotates them in opposite directions, so that the first tightening screw 610 and the second tightening screw 620 are coupled or released. can If the first tightening screw 610 and the second tightening screw 620 rotate in the coupling direction, the first screw head 611 and the second screw head 621 become closer to each other as they rotate, and the tightening bundle 500 The first and second frames 110 and 120 may be fixed by pressing the inner surfaces of the first and second frames 110 and 120 .
