Description
connector
[0001] The present invention relates to a one-sided detachable bolt connector for enabling connection support with greater load-bearing capacity in the production of pipe assemblies such as furniture or construction frame structures; a pipe connector for general-purpose use in which multiple piping pipes are connected in various forms; a sliding connector for a frame structure used as a component to improve the convenience of assembly and construction of pipes forming the frame during the production and installation process of a frame structure utilized as a building or household goods; and an assembly-type modular furniture structure that enables the production of furniture of various sizes and shapes according to application by using assembly components such as a cube-shaped connector body, connecting bolts, and brackets for fixing plates.
[0002] Generally, furniture such as display stands and shelves is assembled according to its intended purpose for displaying various items. Recently, modular display stands are being used, which allow for the assembly of desired structures by connecting metal pipes of a fixed length, made of materials such as stainless steel or aluminum, using brackets.
[0003] Assembly furniture of this type offers the advantage of being relatively easy to assemble and disassemble, allowing for easy modification of size and structure into desired forms. Furthermore, its lightweight nature enables easy relocation and installation. Consequently, such furniture is widely used not only for interior decoration but also as structures for product display and exhibition. However, a problem with this type of DIY modular assembly furniture is that since connectors are forcibly hammered onto stainless steel rods, the connection points can become deformed when the rods are separated after use, rendering them unusable.
[0004] Furthermore, since conventional stainless steel rods must be manufactured as finished products in factories and transported to installation sites, there are many difficulties in transporting and installing bulky items such as display cases. Additionally, the rod material used in modular furniture has been limited to stainless steel, making it difficult to produce heavy modules in various colors.
[0005] To address this, prior art has disclosed a protruding bolt connector in which multiple bolts can be fastened to the connector body to facilitate the assembly and connection of prefabricated furniture. However, the bolt connectors in prior art had the inconvenience of requiring a total of 12 types of connectors, ranging from 1 to 6 ports depending on the pipe assembly direction, including R-type (right-hand thread) and L-type (left-hand thread) connectors, which resulted in increased material and item costs. Additionally, since there was no connection port for partial expansion, there was the inconvenience of having to perform partial disassembly, replace the connector, and then reassemble the unit when expanding.
[0006] Generally, water supply devices such as water purifiers, washing machines, and sinks are designed to allow water to flow in or out, and to facilitate this, drainage pipes are connected to the water supply devices to guide the movement of water. In this case, when another water supply device is installed in a facility where a water supply device and the connected drainage pipes are already installed and in operation, it is desirable to connect the pipes for the newly installed water supply device to the existing drainage pipes in order to simplify the drainage system and prevent unnecessary waste of resources.
[0007] Meanwhile, depending on the installation location, pipes are connected in a cross shape, straight shape, T shape, L shape, etc., and pipe connector parts are assembled at the pipe connection points. However, in the prior art, connectors have limitations in variability of use and increased material costs because various types of connectors must be individually provided depending on the pipe connection type.
[0008] Generally, frame structures are modular furniture forms where each component is independent, allowing users to assemble them as desired. This offers excellent versatility and the advantage of efficient space utilization as they can be configured and assembled according to the shape of the space. Furthermore, because they are constructed with a modular structure that allows for assembly and disassembly, they facilitate easy relocation, installation, and shape modification. Consequently, they are widely used not only in buildings such as greenhouses, logistics warehouses, and country houses, but also for DIY interior furniture, product display furniture, exhibition structures, and camping. However, conventional frame structures feature a fixed connector structure, which limits variability in size and shape according to application. This has resulted in the inconvenience of having to provide separate structures of different sizes and uses.
[0009] Generally, modular furniture offers excellent versatility because each component is independent and can be assembled as desired by the user; furthermore, it has the advantage of allowing for efficient use of space as it is configured and assembled according to the shape of the space.
[0010] In addition, because it is constructed with a modular structure that allows for assembly and disassembly, it is easy to move, install, and change its shape, making it widely used as DIY interior furniture, display furniture for products, and exhibition structures. However, in conventional modular furniture, the original shape of the connector and pipe was damaged when connecting pipes to the connectors by hammering them forcibly, making it difficult to maintain the original function upon reassembly. Furthermore, regarding the method of fixing the panels to the frame forming the furniture structure, there were limitations in material selection because the method involved press-forming steel plates and using an elastic interlocking mechanism.
[0011] The purpose of the present invention is to provide a one-sided separable bolt connector that can solve the problems of the past through a structure in which screw protrusions are integrally formed in one, three, or five places on the connector body and a screw groove is formed on one side.
[0012] Another objective of the present invention is to provide a universal connector that can be variably used at various pipe assembly locations.
[0013] Another objective of the present invention is to provide a sliding connector for a frame structure that improves the use and range of application of the frame structure by utilizing a sliding connector component for improved variability.
[0014] An additional objective of the present invention is to provide modular furniture using connectors and brackets that maximizes the strengths of prefabricated modular furniture and enables its application in various industrial fields by using assembly parts such as cube-shaped connectors, connecting bolts, brackets, plates, and pipes to produce furniture of various sizes and shapes according to use.
[0015] A connector according to the present invention is characterized by comprising: a connector body in the shape of a cube; a screw projection integrally protruding from the outer side of the connector body; a screw groove in the shape of a female screw thread formed on the surface of the connector body where the screw projection is not formed, for fastening of a bidirectional bolt; a pipe having bolt portions formed at both ends so as to selectively fasten screws to each of the three through holes formed in the shape of female screws on the six sides of the connector body; a sliding connector body forming a ring shape to enable sliding movement along the pipe and for connecting and assembling a plurality of pipes; a bolt hole formed on one side of the connector body for fastening of a fixing bolt for temporary fixing; and a connecting bolt configured on the outer side of the connector body to connect one end of the pipe.
[0016] The one-sided detachable bolt connector of the present invention, which has screw protrusions integrally formed in 1-way, 3-way, or 5-way configurations, allows for use in 2-way, 4-way, or 6-way forms by attaching and detaching a bidirectional bolt from one side, thereby improving the convenience of use when manufacturing modular assembly. In particular, while a total of 12 types of connectors—1-way, 2-way, 3-way, 4-way, 5-way, and 6-way—were previously required in R-type and L-type configurations, the present invention requires only 6 types of connectors—1-way and 2-way, 3-way and 4-way, and 5-way and 6-way—in R-type and L-type configurations, thereby reducing manufacturing costs. Additionally, it offers the advantage of facilitating continuous expansion work due to the screw groove.
[0017] The pipe connector of the present invention enables pipes to be connected and assembled in various directions, thereby improving versatility and consequently enhancing ease of use and variability. In particular, by providing a single pipe connector that can be used in various locations, it offers the advantage of reducing product costs.
[0018] The sliding connector for a frame structure according to the present invention utilizes the positional movement and variability of the functional sliding connector during the assembly and installation process of the frame structure to enhance the range of application of the frame structure not only in buildings such as glass greenhouses and country houses but also in furniture and camping equipment. In particular, by using a sliding connector in the middle to connect pipes at right angles without cutting the pipes during the manufacturing process, productivity can be improved by minimizing cutting work. Furthermore, it offers the advantage of improved mobility and storage capabilities through differences in pipe diameters.
[0019] The modular furniture of the present invention creates a cuboid frame by connecting a cube-shaped connector body, connecting bolts, and connecting pipes to each other, and fixes a panel to the frame structure using a panel fixing bracket. This allows for the production of furniture of various sizes and shapes according to the intended use, thereby reducing manufacturing costs and enabling application in various industrial fields. In particular, the connection between brackets is made by a bracket-type connector, thereby providing the advantage of maximizing structural stability.

[0068] The advantages and features of the present invention and the methods for achieving them will become clear by referring to the embodiments described in detail below together with the accompanying drawings.
[0069] The present invention will be described in detail below with reference to the attached drawings.
[0070] First, the configuration of a one-sided detachable bolt connector according to one embodiment of the present invention is as follows through FIGS. 1 to 7.
[0071] The bolt connector in the present embodiment comprises a connector body (10, 10') having a cube shape, a screw projection (20, 20') integrally protruding from the outer side of the connector body (10, 10'), and a screw groove (11, 11') formed to a certain depth on the surface of the connector body (10, 10') where the screw projection is not formed.
[0072] At this time, the screw protrusions (20, 20') are manufactured to form an integrated structure with the connector body (10, 10') by various methods. Additionally, the screw protrusions (20, 20') are provided in a 1-way, 3-way, or 5-way form to form an integrated structure with the connector body (10, 10'). Meanwhile, the screw grooves (11, 11') have female screw threads formed on their inner surface so that the bidirectional bolts (30, 30') can be selectively attached or detached.
[0073] In addition, the above-mentioned bidirectional bolt (30, 30') has a structure in which a first-stage bolt part (31, 31') on one side and a second-stage bolt part (32, 32') on the other side are fastened to the screw groove (11, 11'), and the diameter of the second-stage bolt part (32, 32') is increased compared to the first-stage bolt part (31, 31') inserted into the screw groove (11, 11'). In the drawings, 50, which is not described, represents a connecting pipe, and screw grooves (51, 51') for fastening the bidirectional bolt (30, 30') are formed on the inner surface of both ends of the pipe (50), and it can be seen that the screw grooves (51, 51') consist of an R-direction screw groove (51) and an L-direction screw groove (51').
[0074] Meanwhile, the integrated screw projection (20, 20') in this embodiment may be provided in one direction as in FIG. 1 (first embodiment), three directions as in FIG. 4 (second embodiment), or five directions as in FIG. 6 (third embodiment).
[0075] In addition, the screw direction of the screw groove (11, 11'), screw projection (20, 20'), and bidirectional bolt (30, 30') is configured as R-type (right-hand screw) and L-type (left-hand screw), respectively. The screw projection (20, 20') and the two-stage bolt portion (32, 32') of the bidirectional bolt (30, 30'), which are integrally protruded on the outer side of the connector body (10, 10'), are aligned with the screw grooves (51, 51') at both ends of the pipe (50) and rotate the pipe (50) in one direction to enable attachment and detachment operation.
[0076] Let us examine the effects of using the one-sided detachable bolt connector of the present invention, which has such a configuration.
[0077] The bolt connector in this embodiment is used for manufacturing modular construction materials such as prefabricated furniture or frame construction at a construction site. Since the connector body (10, 10') has screw protrusions (20, 20') formed integrally in 1 direction, 3 directions, and 5 directions, it can be used as a 1 / 2 hole, 3 / 4 hole, or 5 / 6 hole connector by attaching and detaching a two-way bolt (30, 30') to a screw groove (11, 11') machined on one side of the connector body (10, 10').
[0078] That is, it can be utilized as a 1, 3, 5-hole connector in which the pipe (50) is connected in the 1, 3, and 5 directions as a basic type, and if it is to be used as a 2, 4, and 6-hole connector, the pipe (50) can be connected in the 2, 4, and 6 directions by additionally screwing a bidirectional bolt (30, 30') into the screw groove (11, 11'). In addition, it can be provided in R-type and L-type respectively depending on the screw direction so that selective use is possible.
[0079] Meanwhile, FIG. 8 shows the state of furniture assembly using the protruding connector and pipe of the present invention, and FIG. 9 shows the order of the assembly process. After assembling the rectangular modules on both sides as in steps 1 and 2, the assembly of the connecting pipe (50) can be performed in the order of step 3. That is, since one side of the pipe (50) has an R-shaped screw fastening structure and the other side has an L-shaped screw fastening structure, assembly with the connector bodies on both sides (10, 10') is achieved by simply rotating the pipe (50) in one direction, and disassembly is achieved by rotating it in the opposite direction, so it can be seen that a more convenient assembly process can be performed.
[0080] Accordingly, the bolt connector of the present invention has screw protrusions integrally formed in 1, 3, or 5 directions, and can be used in 2, 4, or 6 directions by attaching and detaching a bidirectional bolt from one side, thereby exhibiting the effect of improving convenience of use when manufacturing an assembly module.
[0081] In particular, previously, a total of 12 types of 1-port / 2-port / 3-port / 4-port / 5-port / 6-port connectors were required, each in R-type and L-type, but in the present invention, only a total of 6 types of 1-port and 2-port / 3-port and 4-port / 5-port and 6-port connectors are required, each in R-type and L-type, thereby reducing the manufacturing cost of the product.
[0082] In addition, it demonstrates the advantage that continuous expansion work can be easily performed due to the screw groove. Meanwhile, FIGS. 10 and 11 show the form of use of an anti-loosening bolt according to the fourth embodiment of the present invention, wherein a female screw groove (31a, 31a') is machined and formed at the tip of the first bolt portion (31, 31') of a bidirectional bolt (30, 30'), and an anti-loosening bolt (40, 40') is fastened inside the screw groove (11, 11') of the corresponding connector body (10, 10'), and the anti-loosening bolt (40, 40') is fastened through a hollow groove (21, 21') that penetrates the screw projection (20, 20').
[0083] When such a configuration is achieved, the anti-loosening bolt (40, 40') is inserted through the hollow groove (21, 21') of the opposite screw projection (20, 20') while the bidirectional bolt (30, 30') is screwed into the screw groove (11, 11') of the connector body (10, 10') to be screwed into the female screw groove (31a, 31a'), thereby preventing the bidirectional bolt (30, 30') from loosening and maintaining a more stable assembly state.
[0084] Furthermore, although specific embodiments of the present invention have been described and illustrated above, it is obvious to those skilled in the art that the bolt connector structure of the present invention can be implemented with various modifications.
[0085] For example, the length and diameter of the connector body, screw groove, screw projection, and bidirectional bolt shown in the above embodiment can be manufactured and used in various sizes and shapes as needed.
[0086] In the description, R type refers to a right-hand screw type, and L type refers to a left-hand screw type.
[0087] First, the structure of a pipe connector for general-purpose use according to the second embodiment of the present invention is described in FIGS. 12 to 18 as follows.
[0088] The pipe connector in this embodiment comprises an R-shaped and L-shaped connector body (10, 10') forming a cube shape, through holes (20, 20') formed in the shape of R-shaped and L-shaped female screw threads that penetrate six sides of the connector body (10, 10'), and a piping pipe (30) that is selectively screw-fastened to each of the through holes (20, 20'). That is, three through holes (20, 20') are formed through the connector body (10, 10'), which is molded into a cube shape, in a three-dimensional direction, thereby enabling the selective assembly of the piping pipe (30) in all six directions.
[0089] At this time, the above-mentioned pipe (30) has a hollow structure to allow fluid flow inside, and bolt portions (31, 31') with R-shaped and L-shaped male threads are machined and formed at both ends so that screw fastening can be done into the through hole (20). In addition, in the part of the through hole (20, 20') where the pipe (30) is not fastened, a finishing cap (40, 40') with R-shaped and L-shaped threads machined as shown in FIG. 16 is attached.
[0090] Let us examine the effects of using the pipe connector of the present invention, which has such a configuration.
[0091] The pipe connector of the present invention is formed such that through holes (20, 20') are formed in six directions in the shape of female screws in the connector body (10, 10') which has a cuboidal shape, thus enabling general use through the connection of a piping pipe (30). That is, in this embodiment, two piping pipes (30) are connected and assembled in an "L" shape centered on the connector body (10, 10'), and the bolt portions (31, 31') formed at the ends of the piping pipes (30) are connected to each of the two through holes (20, 20') by screw fastening.
[0092] In particular, since the bolt portion (31) on one side of the pipe (30) has an R-shaped thread and the bolt portion (31') on the other side has an L-shaped thread, it can be seen that assembly with the pipe connectors (10, 10') on both sides can be achieved by simply rotating the pipe (30) in one direction, and disassembly can be achieved by rotating it in the opposite direction, thereby enabling a more convenient assembly process.
[0093] In addition, the remaining four through holes (20, 20') where the pipe (30) is not connected are assembled by fastening the end caps (40, 40') with bolts, thereby preventing the exposure of the through holes (20, 20'). This enables assembly, thereby improving versatility and enhancing ease of use and variability. In particular, by providing a single pipe connector, it can be used in various locations, which offers the advantage of reducing material costs.
[0094] And, although specific embodiments of the present invention have been described and illustrated above, it is obvious that the pipe connector structure of the present invention can be implemented in various modified ways by those skilled in the art. For example, in the above embodiments and drawings, the connection shape of the piping pipe is shown in three shapes, but in addition to the cross shape, straight shape, T shape, and L shape, various three-dimensional pipe connection structures such as umbrella shape can be implemented.
[0095] Hereinafter, the configuration of a sliding connector for a frame structure according to the third embodiment of the present invention is described in reference to FIGS. 20 to 27 as follows.
[0096] In the present embodiment, the frame structure is configured such that a plurality of pipes (10) are assembled by a connector member. At this time, the connector member in the present invention is a sliding connector (20) capable of moving along the pipes. The sliding connector (20) comprises a connector body (21) having a ring shape, a bolt hole (22) formed on one side of the connector body (21) for fastening a fixing bolt (30), and a connecting bolt (23) integrally formed with the connector body (21) to which one end of the pipe (10) is connected. A female screw thread is machined on both ends of the pipe (10) to enable the bolting of the connecting bolt (23).
[0097] At this time, the connecting bolt (23) is configured in one direction as shown in FIGS. 21 and 22 so that the pipe (10) is connected in a 3-hole type, and as shown in FIG. 4, it is provided in four types of 2-way (4-hole type), 3-way (5-hole type), and 4-way (6-hole type), and it is preferable to provide a total of eight types by providing the threads of the connecting bolt (23) in the R direction and L direction, respectively. In particular, in the case of a 4-way structure, it can be seen that three connecting bolts (23) are provided integrally with the connector body part (21), and one detachable connecting bolt (23) has a detachable bolt part (23a) provided at the tip so that it can be attached to and detached from the bolt hole (22).
[0098] Meanwhile, the pipe (10) may be further connected by a pipe connector (40) to extend its length. The pipe connector (40) is provided with a first bolt portion (41) and a second bolt portion (42) at both ends, forming a mutually symmetrical shape with respect to a stepped middle portion (43). Additionally, it can be seen through the cross-sectional view of FIG. 3 that a reinforcing portion (22') is provided protruding at a certain height along the outer circumference of the bolt hole (22) to ensure stable fixation of the fixing bolt (30).
[0099] We will now examine the effects of the assembly and use of the frame structure of the present invention, which has such a configuration.
[0100] Since the frame structure of the present invention is an assembly structure using a plurality of pipes (10) and sliding connectors (20), it can be assembled and used to form the framework of buildings such as glass greenhouses, country houses, and logistics warehouses, or household goods of various shapes and sizes such as shelves, tables, and storage cabinets. That is, multiple sliding connectors (20) of the present invention are inserted at both ends and in the middle of a pipe (10) of a certain length so that they can be assembled and connected with other pipes (10).
[0101] At this time, the sliding connector (20) used can be selectively used among four types (3-hole, 4-hole, 5-hole, 6-hole) of sliding connectors (20) depending on the position and the number of pipes (10) assembled. In particular, during the process of screwing the pipe (10) by rotating it at the connecting bolt (23) portion of the sliding connector (20), the sliding connector (20) can be prevented from moving by fixing it at the bolt hole (22) portion by fastening a fixing bolt (30). Meanwhile, if it is necessary to extend the length of the pipe (10), it can be extended using a pipe connector (40) as shown in FIGS. 26 and 27.
[0102] Accordingly, the present invention demonstrates the effect of improving the range of application of a frame structure not only in buildings such as glass greenhouses and country houses, but also in furniture or camping equipment, by utilizing the positional movement and variability of a functional sliding connector during the assembly and installation process of the frame structure. In particular, during the manufacturing process, the pipes can be connected in a right-angle direction by using a sliding connector in the middle without cutting the pipes, thereby improving productivity by minimizing cutting work. Additionally, it demonstrates the advantage of improving mobility and storage through the difference in pipe diameters. Meanwhile, FIGS. 28 to 30 show a configuration according to an embodiment of the present invention, wherein the first bolt part (41) and the second bolt part (42) have mutually different diameters (d <D))을 이루고, 이와 대응되는 파이프(10)는 일측 파이프(10')가 타측 파이프(10")에 인입 가능하도록 상이한 구경(d<D))을 이루게 된다.
[0103] With this configuration, since the diameters of the pipes (10', 10") are different, the smaller diameter pipe (10') can be inserted into the larger diameter pipe (10") for storage during transport or storage, thereby providing the advantage of improving ease of use.
[0104] Additionally, FIGS. 31 to 35 show a form in which the sliding connector (20) of the present invention is applied to a building roof truss frame structure according to an embodiment of the present invention. A truss connecting bolt (23'), which allows for the connection of truss pipes (10') forming the roof frame, is additionally configured to form a detachable connecting bolt (23") for connecting pipes (10) that are connected vertically and horizontally, and a detachable groove (21') in the form of a female screw is formed through the connector body (21) so that the detachable connecting bolt (23") can be attached and detached. That is, the sliding connector (20) of the present invention, which is fitted so as to be slidably movable on the pipe (10), is connected to the truss connecting bolt (23') at the location where it is connected to the truss pipe (10'), thereby making the construction and assembly work of the roof truss frame structure easier.
[0105] In particular, the angle and number of truss connecting bolts (23') can be varied according to the slope angle (30 degrees - 12 angles, 45 degrees - 8 angles, 22.5 degrees - 16 angles) required for working on the roof structure, and it can be seen that by providing such sliding connectors (20) in a left-right symmetrical form, the construction of the building roof structure can be carried out more quickly and easily. In addition, it demonstrates the advantage of being able to use appropriately according to the roof frame construction location through combined use with detachable connecting bolts (23").
[0106] Additionally, FIGS. 36 to 39 show a sliding connector (20) structure according to an embodiment of the present invention, wherein a plurality of connecting bolts (23) are configured radially around the connector body (21), and all connecting bolts (23) may be formed integrally, or, if necessary, an integral connecting bolt (23) and a detachable connecting bolt (23") may be provided alternately. At this time, it can be seen that a detachable groove (21') in the form of a female screw is formed through the connector body (21) to enable the detachable connecting bolt (23") to be attached or detached. Furthermore, as can be seen in the drawings, 6, 8, or 12 connecting bolts (23, 23") may be selectively provided.
[0107] With such a configuration, it can be seen that a plurality of pipes (10) can be connected to the sliding connector (20) of the present invention, and that a detachable connecting bolt (23) can be fastened only to the pipe connection part through the detachable groove (21') structure, thereby improving functionality and variability.
[0108] Furthermore, although specific embodiments of the present invention have been described and illustrated above, it is obvious that the sliding connector structure of the present invention can be implemented with various modifications by those skilled in the art. For example, in the above embodiments, the sliding connector was described and illustrated as having a 3-hole to 6-hole structure, but if necessary, it can be manufactured and used with 7 or more holes through the additional configuration of connecting bolts. In addition, by varying the diameter and thickness of the pipe and the sliding connector, it can be used for manufacturing structures requiring large shear force or for manufacturing structures for general modular furniture that do not require relatively large loads.
[0109] Hereinafter, the configuration of a modular furniture using a bracket according to the fourth embodiment of the present invention is as follows through FIGS. 40 to 55.
[0110] The modular furniture in this embodiment comprises a plurality of connectors (10, 11, 12) formed at each corner of the furniture, a connecting pipe (20) assembled and connected between the connectors (10, 11, 12), a square-shaped plate (40) formed to finish the square surface formed by the assembly of the connecting pipe (20), a plurality of brackets (30) provided at each corner of the plate (40) to provide support, and a connecting member (50) for connecting and supporting the plurality of brackets (30) to each other.
[0111] At this time, the connector (10, 11, 12) in the present invention is composed of a connector body (10) having a cube shape with a female screw-shaped bolt hole (10a) formed through it in 6 directions, and first and second connecting bolts (11, 12) that are screw-fastened to the connector body (10).
[0112] In particular, the first connecting bolt (11) fastened to one side of the connector body (10) is a two-way bolt with male threads (11a, 11b) formed on both sides so that it is screw-fastened to the connector body (10) and the connecting pipe (20), and the second connecting bolt (12) fastened to the other side of the connector body (10) has a male thread (12a) formed on one side so that it is screw-fastened to the bolt hole (10a) of the connector body (10), and a fitting part (12b) formed on the other side so that it is assembled to the connecting pipe (20) by a forced fitting method without thread processing.
[0113] It can be seen that a stopper (11c, 12c) is provided protruding from the middle of each of the first and second connecting bolts (11, 12), and an air groove (12') is formed in the fitting part (12b) to allow air to be discharged during the fitting process with the connecting pipe (20). Additionally, the connecting pipe (20) has a bolt fastening part (21) with female screw threads formed at one end corresponding to the first connecting bolt (11), and a forced fitting part (22) formed at the other end corresponding to the second connecting bolt (12).
[0114] In a modular furniture assembled in this way, five of the six sides are fixed and the front is openable. Therefore, when the five panels are fastened with fixing bolts using brackets (30) and 2- and 3-hole bracket-type connectors (50) on the top, bottom, left, and right sides, the pipes (20) and panels (40) forming the frame can be stably fixed.
[0115] Meanwhile, in the present invention, the bracket (30) has an inlet groove (31) formed so that the corner portion of the plate (40) can be inserted, and a connector seating groove (32) formed at the corner side so that the connector (50) can be seated is formed with a certain step, and a fastening hole (33) is formed through the connector seating groove (32) so that a fastening means (piece, bolt, etc.) for fixing with the connector (50) is fastened, and an inclined surface (31a) for surface contact with the plate (40) is formed inside the inlet groove (31), and both sides of the inlet groove (31) have an open portion (31b), and a pipe support groove (31c) for supporting the connecting pipe (20) is formed on the side wall surface, as can be seen through FIG. 50 and FIG. 51.
[0116] Additionally, the plate (40) has a beveled surface (41) formed at the corner so that it can make surface contact with the beveled surface (31a). Furthermore, the bracket (30) has a cap fastening hole (34) formed therein for fastening a silicone anti-movement cap (60) to prevent movement of the plate (40).
[0117] Meanwhile, the above connector (50) is preferably formed in a bracket shape so that it can be connected to the bracket (30) on two or three sides, and a fastening hole (53) is formed on one side so that it can be fastened to the bracket (30) by a fastening means (bolt, screw, etc.).
[0118] We will now examine the effects of the assembly of the modular furniture utilizing the bracket of the present invention, which has such a configuration.
[0119] In order to manufacture the frame forming the basic skeleton of the modular furniture of the present invention, assembly and fastening work is performed using a connector and a connecting pipe (20) composed of a connector body (10) and connecting bolts (11, 12). That is, in order to assemble and support both ends of the connecting pipe (20), the first connecting bolt (11) and the second connecting bolt (12) are fastened to the connector body (10) which has a cube shape. In this case, one side of the connecting pipe (20) is screw-fastened with the first connecting bolt (11), and the other side is connected to the second connecting bolt (12) by a forced fitting method. Thus, prior to this, the connection work of the connecting pipe (20) is performed while the first connecting bolt (11) and the second connecting bolt (12) are each bolt-fastened to the connector body (10).
[0120] At this time, in the forced fitting method, if the diameter of the rod portion of the second connecting bolt (12) is processed to be slightly smaller (0.02~0.05mm) than the inner diameter of the forced fitting portion (22) of the standardized connecting pipe (20), the inner diameter of the standardized pipe also has a tolerance range, so it is tight rather than loose, and if it is lightly tapped with a tool such as a wooden mallet, the gap can be minimized and the fitting connection can be achieved. Meanwhile, when assembling the connecting pipe (20) that forms the frame of the furniture with the connector and then assembling the panel (40) that will form the wall surface of the structure, support is provided by the bracket (30). With the bracket (30) attached to each corner of the chamfered panel (40), the brackets (30) that meet at a right angle at the corner are connected to each other by a connecting member (50) that forms a bracket-shaped structure.
[0121] At this time, since the bracket (30) has a stepped connection groove (32), the connection (50) can be maintained in a stable fastening state. By using a connection bolt, the bracket (30) can be supported from two or three sides, thereby allowing the plate (40) to be fixed more stably. Additionally, when the corner portion of the plate (40) is inserted into the insertion groove (31) of the bracket (30), the anti-movement cap (60) is fastened to the cap fastening hole (34), thereby preventing the plate (40) from shaking.
[0122] In addition, since pipe support grooves (31c) are formed on both sides of the bracket (30), it can be seen that stable support can be achieved for the connecting pipe (20) that has been assembled first.
[0123] Accordingly, the modular furniture of the present invention creates a cuboid frame by connecting a cube-shaped connector body, a connecting bolt, and a connecting pipe, and fixes a panel to the frame structure using a bracket for fixing the panel. This allows for the production of furniture of various sizes and shapes according to the intended use, thereby reducing manufacturing costs and enabling application in various industrial fields. In particular, the connection between brackets is made by a bracket-type connector, which provides the advantage of improving structural stability.
[0124] The connector according to the present invention can be applied to furniture or construction structures.
