Description

Technology Field

[0001] The present invention relates to a common bracket structure for inclined shelves and flat shelves and a storage system including the same. More specifically, the invention relates to a common bracket structure for inclined shelves and flat shelves and a storage system including the same, wherein the bracket structure includes a horizontal portion provided at one end of a body part and an inclined portion provided at the other end, and either the horizontal portion or the inclined portion is coupled in such a way that it can be inverted vertically, thereby allowing the mounting form of the shelf to be selectively switched between a flat shelf mode and an inclined shelf mode using only a single type of bracket structure, thereby reducing manufacturing costs and inventory management burdens while preventing stored items from falling out in the event of an external impact. Background Technology

[0002] Recently, the use of storage systems to efficiently store various items within limited spaces is expanding in libraries, reference rooms, office spaces, industrial storage areas, and mobile storage facilities. These storage systems form a storage space through a frame arranged vertically and multiple shelves mounted between the frames, and the height, number, and mounting configuration of the shelves may vary depending on the purpose of use.

[0003] Generally, shelves are often mounted horizontally to store items stably and flatly. However, if the installation area is an environment where impact, movement, or vibration may occur, items loaded on the shelves may slide outward or fall due to shaking, posing a risk of safety accidents as well as compromising loading stability.

[0004] Conventional storage systems mostly consist of standard flat shelf structures, and there was a problem in that the entire storage system had to be replaced, such as by ordering a separate custom-made product, if inclined shelves were required for the installation environment. Consequently, from the manufacturer's perspective, manufacturing costs increased, and the burden of inventory management grew as flat shelf and inclined shelf components had to be stored and managed separately. Furthermore, if users did not consider this in advance, they had no choice but to discard their existing storage system and purchase a new one, which presented a limitation in that it was difficult to quickly reconfigure the storage system to suit the usage environment.

[0005] Accordingly, there is a demand in the industry for the development of a storage system with a new structure that can achieve standardization of storage system components and efficiency in inventory management by selectively implementing flat shelves and inclined shelves with enhanced mounting stability using only a single bracket member with a simplified structure, while simultaneously maintaining robust bonding strength between the bracket and the frame even under external impact.

[0079] FIG. 2 is a perspective view of a storage system (1) including a common bracket structure for an inclined shelf and a flat shelf according to a preferred embodiment of the present invention, and FIG. 3 is an exploded perspective view of the storage system (1).

[0080] A common bracket structure for an inclined shelf and a flat shelf according to one embodiment of the present invention and a storage system (1) including the same are related to a system that selectively implements a flat shelf mode and an inclined shelf mode by only combining a single type of side bracket (20) in a way that allows for vertical inversion, and physically blocks the detachment of the shelf structure even under external shock or vibration conditions through a multi-point fastening structure. Referring to FIGS. 2 and 3, the storage system (1) of the present invention may include a frame (10), a side bracket (20), a shelf (30), a shelf separator (40), and a fixing bracket (50).

That is, the above-mentioned planar portion (231a) can be bent once outward with respect to one side of the body portion (21) and provided in a planar shape that is extended in a direction approximately perpendicular to the body portion (21). The above-mentioned planar portion (231a) can be arranged horizontally toward the inside of the shelf when the side bracket (20) of the present invention is coupled to the first position, so that the mounting portion (31) of the shelf (30) can be seated on its upper surface in a planar contact. Meanwhile, the above-mentioned planar portion (231a) may be further provided with a protruding surface at both ends, and a fitting wing for fitting and fixing both ends of the horizontal portion (23) to the vertical frame (11).

[0095] The above-mentioned bent portion (231b) is a part that is bent upward from the extended end of the above-mentioned flat portion (231a) toward the above-mentioned inclined portion (25). That is, the above-mentioned bent portion (231b) may be bent once again from the end of the above-mentioned flat portion (231a) and provided in a shape that extends approximately perpendicularly to the above-mentioned flat portion (231a). The above-mentioned bent portion (231b) can perform a locking function that physically blocks the mounting portion (31) of the shelf (30) seated on the above-mentioned horizontal seating portion (231) from sliding outward toward the side bracket (20).

[0096] That is, in the flat shelf mode in which the side bracket (20) of the present invention is coupled to the first position, the flat portion (231a) supports the load of the shelf (30), and the bent portion (231b) prevents the shelf (30) from deviating laterally, so that the shelf (30) can be stably mounted and fixed in the flat shelf mode.

[0097] The inclined portion (25) is the other end of the body portion (21) and is a part provided to enable the shelf (30) to be mounted at an angle when the side bracket (20) of the present invention is coupled to a second position, which is an inclined shelf mode. The inclined portion (25) may be formed to include a V-shaped symmetrical inclined surface from the center of the body portion (21) and may include an inclined seating portion (251).

[0098] Similar to the horizontal portion (23) above, the inclined portion (25) may be formed in a shape that is bent outwardly at the other end of the body portion (21) so that when a pair of side brackets (20) are arranged to face each other, the two inclined portions (25) together form a V-shaped inclined surface that is recessed toward the center of the shelf. The inclined portion (25) may include an inclined seating portion (251).

[0099] The inclined seating portion (251) can be understood as a configuration in which the mounting portion (31) of the shelf (30) is fixedly seated on the inclined portion (25), and may include a flat portion (251a) and a bent portion (251b).

[0100] The above-mentioned flat portion (251a) can be understood as a flat portion that is bent and extended once from the horizontal portion (23), which is one end of the body portion (21). At this time, the above-mentioned flat portion (251a) may be formed by bending in the opposite direction relative to the flat portion (231a) of the horizontal seating portion (231) and the body portion (21).

[0101] In one embodiment, if the flat portion (231a) of the horizontal seating portion (231) is bent outward from one side of the body portion (21), the flat portion (251a) of the inclined seating portion (251) is bent outward from the other side of the body portion (21). Accordingly, the horizontal seating portion (231) and the inclined seating portion (251) are bent outward in opposite directions relative to the body portion (21) and can be formed on one side and the other side of the body portion (21), respectively. Meanwhile, the flat portion (251a) may be a surface protruding at both ends, and may further be provided with fitting wings to secure both ends of the inclined portion (25) to the vertical frame (11).

[0102] The above-mentioned bent portion (251b) is a portion that is bent upward from the extended end of the above-mentioned flat portion (251a) toward the above-mentioned horizontal portion (23). That is, the above-mentioned bent portion (251b) may be bent once again from the end of the above-mentioned flat portion (251a) and provided in a shape that extends approximately vertically relative to the above-mentioned flat portion (251a). The above-mentioned bent portion (251b) can perform a locking function that physically blocks the mounting portion (31) of the shelf (30) seated on the above-mentioned inclined seating portion (251) from sliding outward toward the side bracket (20).

[0103] That is, in the inclined shelf mode in which the side bracket (20) of the present invention is coupled to a second position, the flat portion (251a) supports the load of the shelf (30) in an inclined state, and the bent portion (251b) prevents the shelf (30) from deviating laterally, so that the shelf (30) can be stably mounted and fixed in a V-shaped inclined state.

[0104] Due to this double-sided symmetrical structure, the side bracket (20) of the present invention can always have either a horizontal or inclined mounting portion (231, 251) exposed upward even when inverted vertically, allowing the shelf (30) to be mounted.

[0105] More specifically, when the side bracket (20) of the present invention is coupled to a first position in a flat shelf mode, the horizontal portion (23) is located at the bottom and the inclined portion (25) is located at the top, and at this time, the horizontal seating portion (231) provided at the bottom of one side of the body portion (21) is exposed upward so that the shelf (30) can be mounted horizontally.

[0106] Conversely, when the side bracket (20) of the present invention is coupled to a second position, which is an inclined shelf mode, the horizontal portion (23) is located at the top and the inclined portion (25) is located at the bottom, and at this time, the inclined seating portion (251) provided at the bottom of the other side of the body portion (21) is exposed upward so that the shelf (30) can be mounted at an angle. This second position may be coupled in a vertical inversion with respect to the first position or in a point-symmetric position with respect to the center point of the body (21).

[0107] Through this configuration, the side bracket (20) of the present invention can implement both flat shelf mode and inclined shelf mode using only a single type of member, thereby reducing the burden of having to separately manufacture and manage the members for the flat shelf and the inclined shelf of the conventional method, and enabling rapid shape reconstruction according to the usage environment of the storage system.

[0108] The above fixing hole (27) can be understood as a hole into which a fixing bracket (50), to be described later, is inserted to fix the side bracket (20) to the vertical frame (11). Referring again to FIG. 3, the above fixing hole (27) may be provided as a multi-point fastening part formed in a row at a predetermined interval along the vertical direction at both ends of the left and right sides of the body part (21).

[0109] That is, the fixing hole (27) is formed at the left end and the right end of the body part (21), respectively, so that both sides are simultaneously connected to a pair of left and right vertical frames (11), thereby allowing the side bracket (20) to be stably supported between the vertical frames (11). The fixing hole (27) may include a first fixing hole (271) and a second fixing hole (273).

[0110] The first fixing hole (271) may be a vertically elongated hole for fixing the side bracket (20) to the vertical frame (11). That is, the first fixing hole (271) is formed in a slot shape that extends vertically and is provided at a position communicating with the through hole (111) of the vertical frame (11), so that the side protrusion (51) of the fixing bracket (50), which will be described later, is inserted and passes through it.

[0111] In this way, by forming the first fixing hole (271) as a vertical elongated hole, the height of the side bracket (20) relative to the vertical frame (11) can be adjusted, and the side protrusion (51), which will be described later, can be inserted into the upper side of the first fixing hole (271) and then lowered to be caught, thereby enabling a secure fixation.

[0112] The second fixing hole (273) may include a horizontal elongated hole to prevent shaking through secondary fixation of the side bracket (20). In one embodiment of the present invention, the second fixing hole (273) may be formed in a T-shaped slot positioned parallel to the first fixing hole (271), and is provided so that the fixing projection (53) of the fixing bracket (50), which will be described later, is inserted through it.

[0113] Referring to FIGS. 4 and FIGS. 7, the fixing hole (27) according to one embodiment of the present invention may have a first fixing hole (271) and a second fixing hole (273) positioned as a pair parallel to each other in the left and right directions of the body part (21), and accordingly, a cross-lock structure may be formed in which orthogonal fastening in the vertical direction by the first fixing hole (271) and in the horizontal direction by the second fixing hole (273) is simultaneously achieved between the side bracket (20) and the vertical frame (11) of the present invention.

[0114] With such a structure, the side bracket (20) including the bracket structure of the present invention can be distributed and supported at multiple points against rotational moments in the front-rear and left-right directions applied when an external impact occurs, and significantly reduces the possibility of play occurring or shelf detachment compared to a bracket with a single-point fastening method, thereby ensuring both flexible response to the installation environment and stability.

[0115] The above-mentioned separator coupling hole (29) is a hole into which the coupling projection (41) of the shelf separator (40), which will be described later, is inserted and fixed. Referring to FIG. 4, the separator coupling hole (29) may be formed in multiple numbers at regular intervals in the central part of the body part (21), and more specifically, may be formed in a vertical direction on the horizontal part (23) or in a vertical direction on the inclined part (25) on the central part of the body part (21), thereby allowing the position and angle to be adjusted according to the user's needs.

[0117] FIG. 6 is a perspective view of a fixed bracket (50) according to one embodiment of the present invention, FIG. 7 shows the combination of a side bracket (20) having a bracket structure according to one embodiment of the present invention and a vertical frame (11), and FIG. 8 is a drawing showing the process of combining the side bracket (20) and the fixed bracket (50).

[0118] The above-mentioned fixed bracket (50) can be understood as a fixing member for attaching the above-mentioned side bracket (20) to the side of the frame (10). Referring to FIGS. 6 to 8, the above-mentioned fixed bracket (50) can attach and fix the side bracket (20) and the vertical frame (11) by means of a pair of side protrusions (51) and a fixing projection (53) located on the left and right sides.

[0119] The above-mentioned side protrusion (51) can be understood as being simultaneously inserted into the through hole (111) of the vertical frame (11) and the first fixing hole (271) of the side bracket (20) to mutually bind the vertical frame (11) and the side bracket (20).

[0120] In one embodiment, the side protrusion (51) may be formed to protrude to one side from the main body of the fixing bracket (50), and the protruding end may be provided in a downwardly extended jaw shape. Accordingly, when a worker inserts the side protrusion (51) into the upper side of the through hole (111) and the first fixing hole (271) and lowers it, the downwardly extended jaw catches on the narrowed part of the through hole (111) and the first fixing hole (271), thereby allowing for a secure connection and fixation.

[0121] The above fixing projection (53) can be understood as being inserted into the second fixing hole (273) of the side bracket (20) to secondarily fix the side bracket (20) and thereby prevent shaking and rotation. The above fixing projection (53) may be formed on the side of the side protrusion (51) in the main body of the fixing bracket (50), and as the side protrusion (51) is inserted into the vertical elongated hole of the first fixing hole (271) and the above fixing projection (53) is inserted into the horizontal elongated hole of the second fixing hole (273), the connection between the side bracket (20) and the vertical frame (11) of the present invention can be fixed in a multi-point fastening manner.

[0122] More specifically, referring to FIG. 7, the body portion (21) of the side bracket (20) according to one embodiment of the present invention is coupled in close contact with one side wall of the vertical frame (11), and at this time, the side protrusion (51) of the fixing bracket (50) simultaneously penetrates the through hole (111) of the vertical frame (11) and the first fixing hole (271) of the side bracket (20), thereby allowing these members to be fastened and coupled as a single unit.

[0123] Additionally, referring to FIGS. 8(a) and 8(b), the side protrusion (51) is inserted into the first fixing hole (271) and the fixing projection (53) is inserted into the second fixing hole (273) of the side bracket (20). As shown in FIGS. 8(b) and 8(c), the inserted fixing bracket (50) is pushed downward so that the jaw of the side protrusion (51) and the fixing projection (53) are fitted and fixed into the lower grooves of the first fixing hole (271) and the second fixing hole (273), respectively, thereby providing an additional anti-rotation function that suppresses movement of the side bracket (20) in the front-rear and left-right directions.

[0124] At this time, the first fixing hole (271) is formed as a vertical elongated hole and the second fixing hole (273) is formed as a horizontal elongated hole, thereby enabling a cross-lock structure in which the vertical and horizontal fastenings are orthogonal. Due to this fixing structure, vibrations and moments in the front-rear, left-right, and rotational directions applied when an external impact occurs can be distributed and supported at multiple points, thereby significantly improving the coupling stability between the side bracket (20) and the vertical frame (11), and maximizing the torsional rigidity and mounting stability of the entire storage system (1) of the present invention.

[0125] Meanwhile, the above-mentioned fixed bracket (50) may be provided in multiple numbers depending on the number of side brackets (20) included in the storage system (1) of the present invention, and the fixed bracket (50) may be arranged at each connection point so that each side bracket (20) is simultaneously connected to a pair of vertical frames (11) from both the left and right sides.

[0127] Referring again to FIGS. 2 and FIGS. 3, the shelf (30) can be understood as a shelf panel on which items such as books are placed in the storage system (1) of the present invention. The shelf (30) is mounted on a pair of side brackets (20) to form a horizontal or inclined storage space between the left and right side brackets (20). The shelf (30) may include a mounting portion (31).

[0128] The mounting portion (31) can be understood as a part formed by bending on the lower surface of the shelf (30) to be mounted on the horizontal mounting portion (231) or the inclined mounting portion (251) of the side bracket (20). That is, the mounting portion (31) may be formed by bending downward on the lower surface of both ends of the shelf (30), and when the side bracket (20) of the present invention is coupled in a first position, a flat shelf mode, it may be mounted on the flat portion (231a) of the horizontal mounting portion (231), and when the side bracket (20) is coupled in a second position, an inclined shelf mode, it may be mounted on the flat portion (251a) of the inclined mounting portion (251). In any case, since the mounting portion (31) is prevented from moving sideways by the bent portions (231b, 251b) of the seating portion (231, 251), the shelf (30) can be stably mounted on the side bracket (20).

[0129] Meanwhile, the shelf (30) according to one embodiment of the present invention may further include a reinforcing member (33). The reinforcing member (33) is a reinforcing bead formed in the longitudinal direction from the center of the shelf (30) to withstand a load, and is provided in a bead shape that protrudes or is indented along the longitudinal direction of the shelf from the lower center of the shelf (30), thereby preventing the shelf from sagging or deforming due to the self-weight of the stored items.

[0130] FIG. 9 is a drawing showing a shelf separator (40) according to one embodiment of the present invention.

[0131] Referring to FIG. 9, the shelf separator (40) can be understood as a panel that supports the rear of a loaded item by being positioned between a pair of side brackets (20) of the storage system (1) of the present invention. The shelf separator (40) may further include a folded surface or a reinforcing bead that is folded along the longitudinal direction from the center.

[0132] Additionally, the shelf separator (40) includes at least one pair of connecting protrusions (41) at both ends, so that the connecting protrusions (41) can be inserted and fixed into the separator connecting holes (29) of the side bracket (20), and can perform the function of a partition to separate a pair of shelves (30) positioned in the front and back directions based on the shelf separator (40) by partitioning the space between the pair of side brackets (20) in the front and back directions.

[0134] FIG. 10(a) is a usage state diagram showing the flat shelf mode of a storage system (1) according to one embodiment of the present invention.

[0135] Referring to FIG. 10(a), when the storage system (1) is used in flat shelf mode, the side bracket (20) is coupled to the vertical frame (11) of the frame (10) in a first position. That is, the side bracket (20) is coupled in such a position that the horizontal portion (23) is located at the bottom and the inclined portion (25) is located at the top. At this time, a horizontal mounting portion (231) provided at the bottom of one side of the body portion (21) facing each other is exposed upward from a pair of side brackets (20). The mounting portion (31) of the shelf (30) is mounted on the flat portion (231a) of the horizontal mounting portion (231), thereby horizontally mounting and fixing the shelf (30). At this time, the bending portion (231b) can perform a locking function to prevent lateral displacement by making surface contact with the bending surface of the mounting portion (31).

[0136] FIG. 10(b) is a usage state diagram showing the inclined shelf mode of a storage system (1) according to one embodiment of the present invention.

[0137] Referring to FIG. 10(b), when the storage system (1) is switched to an inclined shelf mode, the user can detach the side bracket (20) combined in the flat shelf mode from the vertical frame (11) together with the fixed bracket (50), and then reassemble the side bracket (20) by flipping it 180 degrees in the up and down direction to the second position. At this time, the side bracket (20) is combined in a position where the horizontal part (23) is located at the top and the inclined part (25) is located at the bottom, and the inclined seating part (251) provided at the bottom of the other side of the body part (21) is exposed upward. The mounting part (31) of the shelf (30) is seated on the flat part (251a) of the inclined seating part (251), so that the shelf (30) is mounted in a structure inclined downward toward the center of the storage system (1).

[0138] At this time, a pair of the above-mentioned side brackets (20) are arranged to face each other, and the inclined portion (25) of each side bracket (20) forms a V-shaped symmetrical structure that is inclined downward toward the center of the storage body. That is, a pair of shelves (30) mounted on the inclined portion (25) with respect to the shelf separator (40) form a downward inclined surface, and the two inclined surfaces meet at the center to form a V-shaped seating space.

[0139] In the storage system (1) of the above-described inclined shelf mode, the weight of the items stored on the shelf (30) is naturally directed to the center of the V-shaped symmetrical structure, that is, the center of the shelf (30), so that the items may be prevented from falling out even in the event of an external impact. In addition, in the storage system (1) of the above-described inclined shelf mode, the load caused by the stored items is concentrated along the inclined surface toward the lower center of the shelf (30), thereby lowering the center of gravity and preventing the entire storage system (1) from tipping over.

[0140] The storage system (1) of the present invention can be selectively assembled into either a flat shelf mode in which the side bracket (20) is coupled to a first position or an inclined shelf mode in which it is coupled to a second position. Depending on the usage environment and purpose, the user can quickly switch the mode of the storage system (1) simply by reversing the side bracket (20) up and down. Additionally, the user can freely switch between the functions of the flat shelf and the inclined shelf without the need for separate additional components or tools, or implement both simultaneously in a single storage system (1).

[0141] In addition, when the storage system (1) of the present invention is used as a mobile rack, wheels or a separate drive unit are provided at the bottom of the support frame (13), thereby allowing it to move along a rail, while preventing the shelf (30) from shaking or detaching due to vibrations occurring during movement by means of the multi-point fastening structure of the present invention. As such, the storage system (1) of the present invention can be utilized in various forms such as a fixed bookshelf, a mobile rack, or an earthquake-resistant storage cabinet, and can simultaneously ensure storage efficiency and safety, particularly in libraries, reference rooms, and storage facilities where preventing falling through the stable placement of stored items is required to be of utmost importance.

[0143] The foregoing description of the present invention is for illustrative purposes only, and those skilled in the art will understand that other specific forms can be easily modified without altering the technical spirit or essential features of the present invention. Therefore, the embodiments described above should be understood as illustrative in all respects and not restrictive. For example, each component described as a single unit may be implemented in a distributed manner, and components described as distributed may likewise be implemented in a combined form.

[0144] The scope of the present invention is defined by the claims set forth below rather than by the detailed description above, and all modifications or variations derived from the meaning and scope of the claims and equivalent concepts thereof should be interpreted as being included within the scope of the present invention.
