Description

Technology Field

[0001] The present invention discloses a kitchen furniture leg having a double load-branching structure configured to simultaneously support two lower cabinets, comprising a body, a lower leg portion connected to the lower end of the body and supported on the floor, an upper plate disposed on the upper side of the body and simultaneously supporting two adjacent lower cabinets, and a pair of fixing protrusions protruding from the upper surface of the upper plate, spaced apart from each other, and inserted into fastening grooves formed on the lower surfaces of two adjacent lower cabinets. Background Technology

[0003] Kitchen furniture is generally composed of multiple base cabinet modules, including sinks, countertops, and storage cabinets, arranged in a straight line or in an L-shape or U-shape. In order to secure a gap from the floor and adjust the level, a structure in which legs (levelers) are installed at the bottom to support these base cabinet modules is widely used.

[0004] In conventional kitchen base cabinet structures, it was common practice to support the load by individually installing a single leg at each corner of each base cabinet module. For example, a structure has been used in which four legs are positioned at each corner of a single rectangular base cabinet module.

[0005] In such a structure, the number of legs increases proportionally as the number of base cabinet modules increases. Consequently, a problem may arise where the number of legs used in the overall kitchen base cabinet structure becomes excessive.

[0006] If the number of legs increases, it leads to higher costs due to the increased number of parts, and there are problems such as increased construction time as the assembly process for installing the legs becomes more complex. In addition, since the height of each leg must be adjusted individually, leveling is cumbersome, and there is a greater possibility that unevenness will occur on the cabinet top depending on the installer's skill level.

[0007] In addition, the placement of multiple legs at each corner of the base cabinet leads to a problem where the lower space becomes cluttered. Since water supply and drainage pipes, drain traps, electrical wires, and gas pipes are often located together in the lower kitchen space, a greater number of legs can restrict pipe placement and make maintenance work inconvenient.

[0008] In particular, even when two adjacent sub-unit modules are placed side by side, independent leg sections are installed on each module; consequently, an inefficient structure is formed in the boundary area between the two modules where adjacent leg sections are redundantly placed. This results in the problem of using more leg sections than the minimum number required for actual load support.

[0009] In addition, when a load is concentrated at a single support point, a rotational moment is generated in the lower section, which may cause shaking or step differences between adjacent lower sections; however, conventional technology has not presented a support structure that structurally suppresses such rotational moments while also branching and transferring the load.

[0010] On the other hand, if the installation location of the legs is limited only to the corners of the base cabinet, the load may not be evenly distributed across the bottom of the cabinet and may become concentrated at specific points. This can lead to problems such as deformation of the cabinet's bottom plate, loosening of fasteners, and unevenness between adjacent modules during long-term use.

[0011] Attempts have been made to reduce the number of leg sections or change their positions to improve this, but conventional technology has not provided a sufficient solution for a structure capable of stably supporting two or more sub-cabinet modules simultaneously with a single leg section. In particular, a leg structure that provides a stable connection while absorbing errors in the bottom structure or fastening position of each adjacent sub-cabinet module has not been proposed.

[0012] Therefore, there has been a continuous demand for a new leg structure capable of simultaneously supporting two adjacent sub-sections with a single leg, while also absorbing fastening position errors and stably transmitting the load. The problem to be solved

[0014] The present invention aims to reduce the number of legs and improve the complexity of the installation process and lower space by enabling two adjacent lower cabinets to be supported simultaneously by a single leg.

[0015] In addition, the objective is to provide a kitchen furniture leg having a double load branching structure that can maintain stable load support and a fastening state while absorbing fastening position errors on the bottom surface of the base cabinet.

[0016] In addition, the objective is to provide a leg that suppresses rotational moments that may occur in a single support structure while allowing the load to be branched and transferred to two lower sections.

[0017] Meanwhile, the technical problems to be solved by the present invention are not limited to those mentioned above, and other technical problems not mentioned will be clearly understood by those skilled in the art to which the present invention belongs from the description below. means of solving the problem

[0019] An embodiment of the present invention provides a lower cabinet leg comprising: a body that supports the bottom surface of the lower cabinet; an upper plate formed on the upper part of the body and in contact with the bottom surface of the lower cabinet; and a pair of fixing protrusions that protrude from the upper surface of the upper plate, are spaced apart from each other, and are independently inserted into fastening grooves formed on the bottom surfaces of two adjacent lower cabinets. The pair of fixing protrusions are configured to support two lower cabinets simultaneously at a single support point while allowing the load to be branched and transferred to each lower cabinet, thereby suppressing rotational moment occurring in a single support structure.

[0020] Additionally, an embodiment of the present invention may provide a leg in which a pair of fixed protrusions are spaced apart from each other along the width direction of an upper plate, and the center of the body is positioned to correspond to the boundary area between two adjacent lower plates.

[0021] In addition, an embodiment of the present invention may provide a leg in which the pair of fixed protrusions form different support points on the bottom surface of the lower cabinet, thereby structurally suppressing rotation of the lower cabinet in the forward, backward, left, and right directions.

[0022] In addition, an embodiment of the present invention can provide a leg support configured such that the pair of fixing protrusions are formed to be independently insertable into the fastening grooves on the bottom surface of each lower cabinet, thereby maintaining support stability even if there is a slight difference in bottom surface height between the two lower cabinets.

[0023] In addition, an embodiment of the present invention may provide a leg in which a load transfer path is formed so that the load acting on the upper plate is branched and transferred to each lower plate through the pair of fixed protrusions.

[0024] Additionally, an embodiment of the present invention may provide a leg that includes a sliding space formed along the width direction inside an upper plate, and each of a pair of fixed protrusions is positioned to be movable within the sliding space.

[0025] Additionally, an embodiment of the present invention may provide a leg that further includes a fixing piece positioned at the center of an upper plate and a pair of elastic bodies connecting the fixing piece and each of a pair of fixing protrusions within a sliding space, wherein each of the pair of fixing protrusions is arranged symmetrically with respect to the fixing piece.

[0026] In addition, an embodiment of the present invention may provide a leg foot comprising a sliding portion in which each of a pair of fixed protrusions moves within a sliding space, an inclined portion extending upward from the sliding portion and having an incline, and an insertion portion extending upward from the inclined portion and inserted into a fastening groove.

[0027] In addition, an embodiment of the present invention may provide a leg that is configured such that, after each of a pair of fixed protrusions is inserted into a fastening groove in the order of an insertion part, an inclined part, and a sliding part, the outer wall of the fastening groove is pressed by the elastic restoring force of an elastic body.

[0028] In addition, an embodiment of the present invention may provide a leg that is set such that, when the elastic body is not compressed, the minimum distance between the inner sides of adjacent inserts is greater than the minimum distance between the fastening grooves of adjacent lower cabinets, and the maximum distance between the outer sides of adjacent inserts is smaller than the maximum distance between the outer walls of the fastening grooves of adjacent lower cabinets. Effects of the invention

[0030] According to the present invention, two adjacent lower cabinets can be simultaneously supported by a single leg, thereby reducing the number of legs, simplifying the installation process, reducing costs, and improving the utilization of the lower space.

[0031] In addition, according to the present invention, the coupling structure of the fixed projection and the upper plate and the variable fastening structure can absorb fastening position errors while maintaining stable load support and a fastening state.

[0032] According to the present invention, support stability is improved because the load is branched and transferred to each lower cabinet while simultaneously supporting two adjacent lower cabinets with a single leg, thereby suppressing rotational moment. In addition, constructability is improved as a stable fastening state can be maintained while absorbing fastening position errors.

[0033] Meanwhile, the effects obtainable from the present invention are not limited to those mentioned above, and other unmentioned effects will be clearly understood by those skilled in the art to which the present invention belongs from the description below. Brief explanation of the drawing

Specific details for implementing the invention

[0036] Hereinafter, embodiments of the present invention will be described in more detail with reference to the accompanying drawings. Embodiments of the present invention may be modified in various forms, and the scope of the present invention should not be interpreted as being limited to the embodiments below. These embodiments are provided to more fully explain the present invention to those with average knowledge in the art. Accordingly, the shapes of the elements in the drawings have been exaggerated to emphasize clearer explanations.

In assigning reference numbers to the components of the drawings, the same reference number is assigned to identical components even if they are located in different drawings, and it is noted in advance that components of other drawings may be cited if necessary when describing the drawings.

[0038] FIG. 1 is a partial front view for explaining a kitchen base cabinet system including legs according to a first embodiment of the present invention, FIG. 2 and FIG. 3 are partial front views for explaining a base cabinet in a kitchen base cabinet system including legs according to a first embodiment of the present invention, FIG. 4 is a front view showing legs according to a first embodiment of the present invention, and FIG. 5 is a plan view showing legs according to a first embodiment of the present invention.

[0039] A kitchen cabinet system according to a first embodiment of the present invention may include two adjacent cabinets, a first cabinet (10) and a second cabinet (20), and a leg (100) configured to simultaneously support the first cabinet (10) and the second cabinet (20). The first cabinet (10) is a one-sided cabinet supported by the leg (100) and a conventional leg (50), and the second cabinet (20) is a other-sided cabinet supported by the leg (100) and a conventional leg (50).

[0040] Referring to FIGS. 2 and 3, in a kitchen lower cabinet system according to the first embodiment of the present invention, two adjacent lower cabinets, a first lower cabinet (10) and a second lower cabinet (20), are arranged side by side to form the kitchen lower cabinet.

[0041] The first lower cabinet (10) and the second lower cabinet (20) are each formed as independent cabinet modules, and each lower cabinet includes a main body structure forming an internal storage space and a bottom frame forming the lower part of the main body.

[0042] The first lower cabinet (10) includes a first lower cabinet bottom frame (11) and a first lower cabinet side frame (15), and the second lower cabinet (20) includes a second lower cabinet bottom frame (21) and a second lower cabinet side frame (25). The first lower cabinet side frame (15) and the second lower cabinet side frame (25) are arranged adjacent to each other to form a structure in which the two lower cabinets are arranged continuously side by side.

[0043] The first lower cabinet (10) and the second lower cabinet (20) are each supported from below through bottom frames (11, 21), and the two bottom frames (11, 21) are spaced apart from each other, while the distance between the lower cabinets is maintained within a certain range according to the kitchen lower cabinet installation specifications.

[0044] A first fastening groove (12) is formed on the lower surface of the first lower cabinet bottom frame (11), and a second fastening groove (22) is formed on the lower surface of the second lower cabinet bottom frame (21). The first fastening groove (12) and the second fastening groove (22) are formed in the center of the bottom surface or the bottom frame area of ​​the corresponding lower cabinet, respectively, and provide a reference position for connecting the lower cabinet to the lower support structure.

[0045] As shown in FIGS. 2 and 3, the first fastening groove (12) and the second fastening groove (22) have adjacent positional relationships when the first lower cabinet (10) and the second lower cabinet (20) are arranged side by side. Accordingly, the two fastening grooves (12, 22) form a structure arranged on the left and right sides based on the boundary area between the lower cabinets.

[0046] With this structure, the first lower cabinet (10) and the second lower cabinet (20) each maintain independent cabinet structures while having arrangement conditions that allow them to share a lower support structure.

[0047] Meanwhile, referring to FIG. 3, a certain distance is formed between the first fastening groove (12) formed in the bottom frame (11) of the first lower cabinet (10) and the second fastening groove (22) formed in the bottom frame (21) of the second lower cabinet (20).

[0048] At this time, the distance between the inner edges facing each other of the first fastening groove (12) and the second fastening groove (22) is defined as the second distance (D2).

[0049] Meanwhile, the outer diameter of the fixing projection (130) inserted into the first fastening groove (12) and the second fastening groove (22) is defined as the first distance (D1), and the first distance (D1) may be formed to have a size that is the same as or similar to the inner diameter of the first fastening groove (12) and the second fastening groove (22). The specific structural meaning and function of this first distance (D1) will be described later.

[0050] As illustrated in FIGS. 4 and 5, the leg (100) may include a body (110), an upper plate (120), a fixed projection (130), and a lower leg portion (140). The body (110) may be formed as an intermediate member connecting the upper plate (120) and the lower leg portion (140). The upper plate (120) may be formed as a plate-like member supporting two lower sections simultaneously.

[0051] Here, the upper plate (120) forms a load transfer path so that the load is branched and transferred to the first lower member (10) and the second lower member (20) through a pair of fixed protrusions (130). Accordingly, rotational moment occurring in a single support structure can be suppressed.

[0052] The body (110) can be formed in a column shape extending along the longitudinal direction, or in a cylindrical or polygonal column shape. These shapes can be appropriately selected depending on the manufacturing method, the securing of rigidity, and load transfer characteristics.

[0053] The upper portion of the body (110) may be formed to be combined with the upper plate (120), and the lower portion of the body (110) may be formed to be combined with the lower leg portion (140). The body (110) may be formed integrally with the upper plate (120) and the lower leg portion (140), or may be formed separately from each and then combined.

[0054] The body (110) can be formed with a hollow interior, thereby allowing sufficient rigidity to be secured while reducing the amount of material used. Additionally, the hollow structure can provide the effect of reducing the overall weight of the leg (100).

[0055] The outer surface of the body (110) is formed to stably support the compressive load generated by the upper load, and may include reinforcing ribs or thickness variation structures as needed.

[0056] The body (110) may have a length set corresponding to the installation height of the lower cabinet (10, 20) and is used together with the height adjustment range of the lower leg part (140) to enable horizontal adjustment of the entire lower cabinet.

[0057] The body (110) formed in this way functions to stably support the load transmitted from two adjacent lower sections (10, 20) with one leg by structurally connecting the upper plate (120) and the lower leg section (140).

[0058] The upper plate (120) is formed as a plate-like member to simultaneously support the bottom surfaces of two adjacent lower cabinets (10, 20). The upper plate (120) is coupled to the upper part of the body (110) and has a structure that extends in the left and right directions relative to the body (110).

[0060] The upper plate (120) can be formed to extend along the longitudinal direction based on a planar shape and formed to have a width greater than the width of the body (110), so as to support the bottom areas of the first lower cabinet (10) and the second lower cabinet (20), respectively. Accordingly, the load transmitted from the two lower cabinets (10, 20) can be distributed and transmitted to the left and right sides based on the body (110).

[0061] The upper surface of the upper plate (120) is configured to have a fixing projection (130) formed protruding therefrom. The fixing projection (130) is positioned in the left and right regions of the upper plate (120) respectively and can be inserted into the first fastening groove (12) of the first lower cabinet (10) and the second fastening groove (22) of the second lower cabinet (20), respectively.

[0062] The upper plate (120) is positioned in direct contact with or close to the bottom frame (11, 21) of the first lower cabinet (10) and the second lower cabinet (20) with the fixed projection (130) inserted therein, so as to directly support the load of the lower cabinet (10, 20).

[0063] Additionally, the upper plate (120) may include a support portion (125) to be stably supported on the body (110). The support portion (125) is an area where the upper plate (120) is supported by the body (110), and is formed to relieve load concentration and improve the bonding stability between the upper plate (120) and the body (110).

[0064] The upper plate (120) may be formed of metal, synthetic resin, or a composite material thereof, and may be designed to have sufficient rigidity to withstand the load transmitted from the lower plate (10, 20).

[0065] The upper plate (120) formed in this way functions as a support reference member that enables two adjacent lower plates (10, 20) to be supported by a single leg (100).

[0066] The support portion (125) is an area formed on the lower surface of the upper plate (120) that contacts the body (110), thereby allowing the upper plate (120) to be stably supported by the body (110). The support portion (125) alleviates the concentration of load between the upper plate (120) and the body (110) and allows the load to be smoothly transferred to the lower leg portion (140) through the body (110).

[0067] The fixing projection (130) is inserted into the first fastening groove (12) and the second fastening groove (22) formed on the bottom surfaces of two adjacent lower cabinets (10, 20), respectively, and functions as a connecting member to fix the position of the leg (100) on the lower cabinets (10, 20).

[0068] The fixed protrusions (130) are formed as a pair on the left and right and are respectively placed in the left and right regions of the upper plate (120). Accordingly, the first lower plate (10) and the second lower plate (20) are individually supported by their respective fixed protrusions (130), while simultaneously being supported by a single leg (100).

[0069] The fixed projection (130) may be formed integrally with the upper plate (120) or formed as a separate member coupled to the upper plate (120). The coupling method of the fixed projection (130) may be appropriately selected depending on the manufacturing process or the conditions for securing rigidity.

[0070] The fixing projection (130) can be formed in a projection shape that extends along the longitudinal direction overall, and its external shape is set so that it can be inserted into the first fastening groove (12) and the second fastening groove (22). The outer diameter of the fixing projection (130) is defined as the first distance (D1), and the first distance (D1) can be formed to have a size that is the same as or similar to the inner diameter of the first fastening groove (12) and the second fastening groove (22).

[0071] With such an outer diameter setting, the fixing projection (130) can be stably positioned without excessive play while inserted into the fastening groove (12, 22), and the relative movement between the lower cabinet (10, 20) and the leg (100) can be restricted.

[0072] Here, the fixed projection (130) can be configured to form different support points to structurally suppress rotation of the lower cabinet in the forward, backward, left, and right directions.

[0073] Additionally, the spacing between a pair of left and right fixed protrusions (130) can be set in relation to a second distance (D2), and the second distance (D2) can be set to correspond to the arrangement relationship between the first fastening groove (12) and the second fastening groove (22) of adjacent lower cabinets (10, 20). Accordingly, the leg (100) can be naturally coupled to the fastening groove (12, 22) even if there is an arrangement error of the lower cabinets (10, 20).

[0074] The fixed projection (130) performs the role of maintaining the positional relationship between the lower plate (10, 20) and the leg (100) during the process in which the load transmitted from the lower plate (10, 20) is transmitted to the body (110) through the upper plate (120).

[0075] The fixed projection (130) formed in this way functions as a key connecting element that enables the leg foot (100) to stably support two adjacent lower sections (10, 20) as a single support structure.

[0076] Meanwhile, referring to FIGS. 1 to 3, a conventional leg (50) can be arranged together with a leg base (100) in a kitchen base cabinet system.

[0077] The conventional legs (50) are conventional support members for supporting the lower portions of individual lower cabinets (10, 20), and are individually placed in the corner area or bottom area of ​​each lower cabinet.

[0078] The leg (50) has a structure that is inserted into and connected to a fastening groove formed on the bottom surface of the lower cabinet (10, 20). At this time, the leg (50) is configured so that one leg supports one lower cabinet and maintains a structurally separated state from the adjacent lower cabinet.

[0079] Since the legs (50) are installed independently on each of the lower cabinets (10) or lower cabinets (20), a separate leg (50) is required for each lower cabinet even when two adjacent lower cabinets are arranged side by side. Accordingly, a structure is formed in which the legs (50) are overlapped in the boundary area between the lower cabinets.

[0080] Additionally, since the leg (50) is inserted into only one fastening groove to support the lower cabinet, it does not provide a function to maintain the positional relationship between the lower cabinets. That is, the first lower cabinet (10) and the second lower cabinet (20) are supported individually by their respective legs (50), and do not perform the role of binding the two lower cabinets into a single support structure.

[0081] Due to this structure, when using conventional legs (50), as the number of lower cabinets increases, the number of legs (50) also increases, and a problem arises where multiple legs are placed within the lower space.

[0082] In addition, since height adjustment must be performed individually for each leg (50) of each lower cabinet (10, 20), leveling work between lower cabinets may become cumbersome, and there is also a possibility that a step difference may occur between adjacent lower cabinets due to construction errors.

[0083] In this way, the conventional legs (50) function as a structure that supports each individual lower section, but do not provide a structure that supports two adjacent lower sections by integrating them into a single support structure.

[0084] The lower leg portion (140) is a support member that is in direct contact with the floor at the bottom of the leg foot (100), and performs the role of transmitting the load of the lower body (10, 20) transmitted through the upper plate (120) and body (110) to the floor.

[0085] The lower leg portion (140) is formed as a single leg structure and is configured to support the load transmitted from two adjacent lower cabinets (10, 20) at a single support point. Accordingly, compared to a structure in which the legs (50) are individually arranged for each lower cabinet, the lower leg portion (140) serves to reduce the number of legs arranged within the lower space.

[0086] The lower leg portion (140) may be formed to be coupled to the lower part of the body (110), and may be formed integrally with the body (110) or formed as a separate member coupled to the body (110). The coupling method may be appropriately selected according to the manufacturing process, assembly, or conditions for securing rigidity.

[0087] The lower leg portion (140) can be configured to be height-adjustable. For example, the lower leg portion (140) can be formed to be movable in the up and down direction by including a screw connection structure, thereby compensating for horizontal errors in the floor or height deviations due to the installation environment.

[0088] With this height adjustment structure, the lower leg portion (140) can function as a reference support point to ensure that two adjacent lower cabinets (10, 20) are aligned at the same height. Accordingly, a step difference can be prevented from occurring at the top of the lower cabinets (10, 20).

[0089] The lower part of the lower leg portion (140) can be formed to make stable contact with the floor, and can be designed with a contact area or shape to secure frictional force with the floor as needed.

[0090] The lower leg portion (140) formed in this way functions as a final support member that allows the leg foot (100) to stably support two adjacent lower sections (10, 20) as a single support structure.

[0092] A second embodiment of the present invention will be described below. The second embodiment is identical to the first embodiment in its basic configuration and operation, but differs in that the shape or arrangement of some components has been changed.

[0093] At this time, regarding the components having the same reference numerals as in the first embodiment in the second embodiment, a detailed description is omitted as they have already been described in the first embodiment.

[0094] FIG. 6 is a partial front view for explaining a kitchen base cabinet system including legs according to a second embodiment of the present invention, and FIGS. 7 to 9 are illustrative diagrams for sequentially explaining the state in which legs according to a second embodiment of the present invention are coupled to a kitchen base cabinet.

[0095] Referring to FIG. 6, the leg (200) according to the second embodiment of the present invention is a support member configured to simultaneously support two adjacent lower members (10, 20).

[0096] The leg (200) basically has a structure that supports the lower cabinet (10, 20) from the top and supports the floor from the bottom, just like the leg of the first embodiment. However, the leg (200) of the second embodiment differs from the first embodiment in that the method of connection and the operation of connection to the lower cabinet are different.

[0097] The leg (200) may be formed with a structure including a body, an upper plate, and a lower leg portion, and this basic configuration is the same as in the first embodiment. Accordingly, the leg (200) forms a load transfer structure that supports the load of the lower body (10, 20) through the upper plate and transfers the load to the lower leg portion through the body.

[0098] The body part (210) is the central structure of the leg (200) and is formed to connect the structure supporting the lower cabinet (10, 20) from the top and the structure supporting the floor from the bottom in the vertical direction.

[0100] The body portion (210) can be formed in a column shape that extends along the longitudinal direction, and is configured such that an upper plate is placed on the upper part and a lower leg portion is placed on the lower part. Accordingly, the load transmitted from the lower unit (10, 20) can be transmitted to the lower leg portion through the body portion (210).

[0102] The body portion (210) may be formed integrally with the upper plate and the lower leg portion, or may be formed as a separate member that is combined with each. This method of combination can be appropriately selected depending on the manufacturing process, assembly, or conditions for securing rigidity.

[0103] In addition, the body part (210) is an area where the load is concentrated when the leg (200) is connected to the lower part (10, 20), so the shape and thickness can be set to ensure sufficient rigidity.

[0104] The body part (210) formed in this way functions as a central connecting member that allows the leg foot (200) according to the second embodiment to stably support two adjacent lower sections (10, 20) as a single support structure.

[0105] The upper plate (220) is formed as a plate-like member to simultaneously support the bottom surfaces of two adjacent lower cabinets (10, 20). The upper plate (220) is coupled to the top of the body portion (210) and has a structure that extends in the left and right directions relative to the body portion (210).

[0106] The upper plate (220) is formed along the width direction and can be formed to have a width greater than the width of the body portion (210). Accordingly, the upper plate (220) can support the bottom areas of the first lower cabinet (10) and the second lower cabinet (20), respectively, and distribute the load transmitted from the two lower cabinets (10, 20) to the left and right.

[0107] Additionally, a sliding space extending along the width direction may be formed inside the upper plate (220). The sliding space provides a space for a pair of fixed protrusions to move in the width direction, thereby allowing the distance error between the fastening grooves of the lower cabinet (10, 20) to be absorbed.

[0108] A fixing piece (230) may be disposed at the center of the upper plate (220), and an elastic body (250) connecting the fixing piece and a pair of fixing protrusions (240) may be disposed within the sliding space. Accordingly, the pair of fixing protrusions (240) can be maintained in a state of left-right symmetry with respect to the fixing piece (230).

[0109] The upper plate (220) is connected to the lower cabinet (10, 20) and is positioned in contact with or close to the bottom surface of the lower cabinet, functioning as a support surface that directly supports the load of the lower cabinet (10, 20).

[0110] The upper plate (220) formed in this manner functions as an upper support member that enables the leg (200) according to the second embodiment to stably support two adjacent lower plates (10, 20) as a single support structure.

[0111] The fixed member (230) is a member fixedly positioned at the center of the width direction of the upper plate (220) and serves to provide a reference point for the movement and pressing action of the fixed protrusions (240) positioned on the left and right sides.

[0112] One side of the elastic body (250) is fixed to each of the left and right sides of the fixed piece (230). Accordingly, the fixed piece (230) functions as a fixed point where the left and right elastic bodies (250) are joined, and forms a structure that transmits elastic force to the fixed projection (240) through the elastic body (250).

[0113] The fixed piece (230) is positioned in a fixed state that does not move relative to the upper plate (220), thereby stably maintaining the reference position when the fixed projection (240) moves in the left and right directions through the sliding part (241).

[0114] Due to this structure, the fixed projection (240) can slide in the left and right directions during the process of being inserted into the fastening groove (12, 22), and after insertion, it can maintain a state of being pressed toward the outer wall of the fastening groove (12, 22) by the elastic restoring force of the elastic body (250).

[0115] That is, the fixed piece (230) controls the left and right sliding range of the fixed projection (240) and functions as a central support member that stably supports the elastic force of the elastic body (250).

[0116] The fixing piece (230) formed in this manner functions as a core reference structure that enables automatic alignment and stable pressure coupling of the fixing projection (240) in the leg foot (200) according to the second embodiment.

[0117] The fixing projection (240) is simultaneously inserted into the first fastening groove (12) and the second fastening groove (22) formed on the bottom surfaces of two adjacent lower cabinets (10, 20), respectively, and functions as a connecting member to allow the leg (200) to be connected to the lower cabinets (10, 20). The fixing projection (240) is formed as a left and right pair and is placed in the left and right regions of the upper plate (220), respectively.

[0119] The fixed projection (240) is configured in a stepped shape including a sliding part (241), an inclined part (242), and an insertion part (243) for stable insertion and coupling into the fastening groove (12, 22) of the lower cabinet (10, 20).

[0120] The sliding part (241) is positioned at the bottom of the fixed projection (240) and is arranged to slide in the left-right direction along the width direction inside the upper plate (220). The other end of the elastic body (250) is connected to one side of the sliding part (241) toward the fixed piece (230), thereby forming a structure in which the sliding part (241) is elastically supported by the elastic force of the elastic body (250).

[0121] The inclined portion (242) is formed by extending upward from the sliding portion (241) and, through its inclined shape, induces the fixing projection (240) to slide in the left and right directions along the step or entrance shape of the fastening groove when it is inserted into the fastening groove (12, 22). Accordingly, positional errors that may occur during the fastening process are absorbed.

[0122] The insertion part (243) is located at the upper end of the fixed projection (240), extends from the upper part of the inclined part (242), and forms a step for primary engagement. The insertion part (243) is first inserted into the fastening groove (12, 22) to perform the function of setting the initial position of the fixed projection (240).

[0123] After the fixed projection (240) is inserted into the fastening groove (12, 22) in the order of the insertion part (243), the inclined part (242), and the sliding part (241), the sliding part (241) is pressed outward by the elastic restoring force of the elastic body (250). Accordingly, the fixed projection (240) maintains a state of pressing against the outer wall of the fastening groove (12, 22), thereby ensuring coupling stability.

[0124] The fixed projection (240) formed in this manner functions as a key coupling element that allows the leg foot (200) according to the second embodiment to combine two adjacent lower members (10, 20) into a single support structure while absorbing fastening errors and maintaining a stable pressure coupling state.

[0125] The elastic body (250) is formed as a member that provides a force to cause the fixed projection (240) to move along the width direction of the upper plate (220) through compression and elastic restoring force. The elastic body (250) is positioned between the fixed piece (230) and the sliding portion (241) of the fixed projection (240) to form a structure that elastically supports the fixed projection (240).

[0126] One side of the elastic body (250) is fixed to the fixed piece (230), and the other side is connected to one side of the sliding part (241). Accordingly, the fixed projection (240) can perform the operation of being pressed or restored in the left and right directions relative to the fixed piece (230) by the elastic force of the elastic body (250).

[0127] In the process of inserting the fixed projection (240) into the fastening groove (12, 22), as the inclined portion (242) moves along the step of the fastening groove, the sliding portion (241) moves toward the fixed piece (230) while compressing the elastic body (250).

[0128] Afterwards, when the fixed projection (240) is fully inserted into the fastening groove (12, 22), the compressed elastic body (250) pushes the sliding part (241) outward by the elastic restoring force, and accordingly, the fixed projection (240) maintains a state of pressing against the outer wall of the fastening groove (12, 22).

[0129] Due to the action of such an elastic body (250), the fixing projection (240) can be stably fixed without play within the fastening groove (12, 22), and a stable bonded state can be maintained even if there is an assembly error or manufacturing error.

[0130] Additionally, the elastic body (250) limits the left and right movement range of the fixed projection (240) and provides a restoring force that ensures the bonded state is stably maintained even during repeated attachment and detachment processes.

[0131] The elastic body (250) formed in this manner functions as a core elastic member that realizes automatic alignment, pressure coupling, and coupling stability of the fixed projection (240) in the leg foot (200) according to the second embodiment.

[0132] Meanwhile, in the process of inserting the fixing projection (240) of the leg (200) according to the second embodiment into the fastening groove (12, 22), a plurality of distance concepts may be defined to explain the relative positional relationship between the fixing projection (240) and the fastening groove (12, 22).

[0133] First, the second distance (D2) is defined as the distance between the mutually facing inner edges of the first fastening groove (12) and the second fastening groove (22). The second distance (D2) represents the minimum separation distance between the fastening grooves (12, 22) when two adjacent lower cabinets (10, 20) are arranged.

[0134] Next, the third distance (D3) is defined as the distance between the inner surfaces facing each other among a pair of left and right fixing protrusions (240) when the insertion portion (243) of the fixing protrusion (240) is initially inserted into the fastening groove (12, 22). The third distance (D3) represents the positional relationship in the initial stage where the fixing protrusion (240) is aligned to correspond to the fastening groove (12, 22).

[0135] Additionally, the fourth distance (D4) is defined as the distance between the outer surfaces of the left and right pair of fixed protrusions (240) located in opposite directions after the fixed protrusion (240) is fully inserted into the fastening groove (12, 22) and is pressed by the elastic restoring force of the elastic body (250). The fourth distance (D4) represents the final coupling state in which the fixed protrusion (240) presses against the outer wall of the fastening groove (12, 22) in the completed fastening state.

[0136] Here, the outer surface of the fastening groove (12, 22) is defined as the surface opposite to the inner surface.

[0137] The second distance (D2), third distance (D3), and fourth distance (D4) defined in this way are used as a standard to explain the positional relationship at each stage in which the fixed projection (240) is inserted into the fastening groove (12, 22) and pressurized.

[0138] Hereinafter, with sequential reference to FIGS. 7 to 9, the process of inserting the fixing projection (240) of the leg (200) according to the second embodiment into the fastening groove (12, 22) of the lower cabinet (10, 20) will be explained.

[0139] In the state illustrated in FIG. 7, the leg (200) is approached in the direction of the bottom surface of the lower cabinet (10, 20), and the insertion part (243) of the fixing projection (240) is positioned to correspond to the entrances of the first fastening groove (12) and the second fastening groove (22), respectively. At this time, the distance between the inner surfaces of the left and right pair of fixing projections (240) forms a third distance (D3), and the third distance (D3) is set to be larger than the second distance (D2). Accordingly, the fixing projection (240) can be initially inserted into the fastening grooves (12, 22) without interference.

[0140] In the state illustrated in FIG. 8, as the leg (200) continues to move upward, the insertion part (243) of the fixing projection (240) enters the fastening groove (12, 22), and subsequently the inclined part (242) comes into contact with the step or inner wall of the fastening groove (12, 22). During this process, the fixing projection (240) is guided in the left and right directions along the inclined surface of the inclined part (242), and a pair of left and right fixing projections (240) come close to each other. Accordingly, the distance between the inner surfaces of the left and right fixing projections (240) gradually decreases from the third distance (D3) and changes to correspond to the second distance (D2).

[0141] At this time, the sliding part (241) of the fixed projection (240) moves in the direction of the fixed piece (230) inside the upper plate (220) and compresses the elastic body (250).

[0142] In the state illustrated in FIG. 9, when the insertion part (243), the inclined part (242), and the sliding part (241) of the fixed projection (240) are sequentially and completely inserted into the fastening groove (12, 22), the compressed elastic body (250) generates an elastic restoring force. Accordingly, the sliding part (241) is pushed outward, and the left and right pair of fixed projections (240) are separated from each other and press against the outer wall of the fastening groove (12, 22).

[0143] In this state, the distance between the outer surfaces of the left and right fixing protrusions (240) forms a fourth distance (D4), and the fourth distance (D4) is set to be smaller than the distance between the outer walls of the fastening grooves (12, 22). Accordingly, the fixing protrusions (240) are maintained in a state of close contact without gap within the fastening grooves (12, 22).

[0144] As a result, the leg (200) according to the second embodiment is inserted into the fastening groove (12, 22) in an automatically aligned state by the interaction of the fixing projection (240), the fixing piece (230), and the elastic body (250), and after insertion is complete, it maintains a stable coupled state by elastic pressure.

[0146] Hereinafter, a kitchen base cabinet system including legs according to a third embodiment of the present invention will be described with reference to FIGS. 10 and 11.

[0147] The third embodiment is identical to the first and second embodiments in basic configuration and operation, but differs in that the arrangement structure of the fastening groove formed on the bottom surface of the lower cabinet is changed.

[0148] At this point, since the components having the same reference numerals as those in the first or second embodiment in the third embodiment have already been described, a detailed description is omitted.

[0149] FIGS. 10 and FIGS. 11 are bottom views for illustrating a kitchen base cabinet system including legs according to a third embodiment of the present invention.

[0150] Referring to FIGS. 10 and 11, a kitchen base cabinet system according to the third embodiment includes a base cabinet set (300).

[0151] The lower cabinet set (300) is formed as an overall structure including a first lower cabinet (310) and a second lower cabinet (320) according to the third embodiment. The first lower cabinet (310) and the second lower cabinet (320) are arranged side by side so as to be adjacent to each other to form the lower part of the kitchen.

[0152] The lower cabinet set (300) is configured to be supported from below by a leg (100), and the leg (100) is positioned at a location corresponding to the boundary area or corner area of ​​the first lower cabinet (310) and the second lower cabinet (320) to support both lower cabinets simultaneously.

[0153] Accordingly, the lower cabinet set (300) has a structure that can stably support two adjacent lower cabinets through a single leg (100) without having to arrange individual legs (50) for each lower cabinet as in the conventional method.

[0154] Additionally, the lower cabinet set (300) includes a structure in which a plurality of fastening grooves are arranged on the bottom surface of the lower cabinet so that the fixing projection (130) of the leg (100) can be selectively coupled. Thus, the lower cabinet set (300) can select various coupling positions of the leg (100) depending on the installation environment or support conditions.

[0155] This type of lower cabinet set (300) provides a basic configuration to expand the application range of the support structure using the leg feet (100) in the third embodiment and to improve construction stability and support reliability.

[0156] The first lower cabinet (310) is one of the cabinet modules constituting the lower part of the kitchen and has a main body structure that forms a storage space inside. The first lower cabinet (310) is configured to be connected to a countertop or upper structure at the top and supported by legs (100) at the bottom.

[0157] The first lower cabinet (310) includes a first lower cabinet bottom frame (311) forming a lower structure and a first lower cabinet side frame (312) forming a side of the lower cabinet. The first lower cabinet bottom frame (311) is a lower structure to which the load of the first lower cabinet (310) is transmitted, and forms an area where a connection with the leg (100) is made.

[0158] A plurality of fastening grooves for connection with the leg feet (100) are formed on the lower surface of the first lower cabinet bottom frame (311). Specifically, a first-1 fastening groove (313) and a first-2 fastening groove (314) are formed in the first lower cabinet bottom frame (311).

[0159] The first-1 fastening groove (313) is a basic fastening groove into which the fixing projection (130) of the leg (100) is inserted, and provides a reference coupling position for supporting the first lower cabinet (310) from below.

[0160] The first-2 fastening groove (314) is formed as a fastening groove positioned further inward than the first-1 fastening groove (313) along the first lower cabinet side frame (312). The first-2 fastening groove (314) is configured to connect two adjacent lower cabinets using the leg feet (100) without using conventional legs (50), or to support by changing the direction of two fixing protrusions (130) at a single corner.

[0161] Accordingly, when using the first-2 fastening groove (314), the support portion by the leg (100) is expanded, and rotation of the lower cabinet (310) is prevented during the construction process, thereby improving support stability.

[0162] The first lower member (310) configured in this manner can flexibly respond to various support conditions required in the third embodiment through a plurality of fastening groove structures to which the fixing projection (130) of the leg (100) can be selectively coupled.

[0163] The second lower cabinet (320) is a lower cabinet arranged side by side with the first lower cabinet (310) and forms a continuous lower kitchen together with the first lower cabinet (310). The second lower cabinet (320) has a main body structure that forms a storage space inside, just like the first lower cabinet (310), and is configured to be supported by legs (100) at the bottom.

[0164] The second lower cabinet (320) includes a second lower cabinet bottom frame (321) forming a lower structure and a second lower cabinet side frame (322) forming a side of the lower cabinet. The second lower cabinet bottom frame (321) is a lower structure to which the load of the second lower cabinet (320) is transmitted, and forms an area where it is connected to the leg (100).

[0165] A plurality of fastening grooves are formed on the lower surface of the second lower cabinet bottom frame (321) for inserting the fixing projection (130) of the leg (100). Specifically, a second-1 fastening groove (323) and a second-2 fastening groove (324) are formed in the second lower cabinet bottom frame (321).

[0166] The 2-1 fastening groove (323) is a basic fastening groove corresponding to the 1-1 fastening groove (313) of the 1st lower cabinet (310), and provides a reference coupling position for supporting the 2nd lower cabinet (320) from below using the leg (100).

[0167] The second-2 fastening groove (324) is formed as a fastening groove positioned further inward than the second-1 fastening groove (323) along the second lower cabinet side frame (322). The second-2 fastening groove (324) is positioned to correspond to the first-2 fastening groove (314) of the first lower cabinet (310), so that two adjacent lower cabinets (310, 320) can be connected using the leg (100), or supported by changing the direction of the two fixing protrusions (130) at a single corner.

[0168] Meanwhile, the distance between the inner edges facing each other between the first-1 fastening groove (313) of the first lower cabinet (310) and the second-1 fastening groove (323) of the second lower cabinet (320) is defined as the second distance (D2). The second distance (D2) is a reference distance representing the minimum separation distance between the fastening grooves when the two adjacent lower cabinets (310, 320) are arranged.

[0169] The second distance (D2) is used as a standard for establishing the arrangement relationship between a pair of fixed protrusions (130) of the leg (100) and provides key dimensional conditions that allow the leg (100) to be simultaneously coupled to the first lower cabinet (310) and the second lower cabinet (320).

[0170] The second lower member (320) configured in this manner enables stable joint support using the leg (100) through the positional relationship defined by the second distance (D2), in particular, the fastening groove arrangement relationship with the first lower member (310).
