Description

Prefabricated clothes drying rack and its connecting members

[0001] The present invention relates to an assembly-type clothes drying rack, and more particularly, to an assembly-type clothes drying rack and its connecting member that can be used firmly and stably while significantly reducing the volume or area of ​​product packaging and maximizing the convenience of assembly.

[0002] A commonly used stand-alone clothes drying rack has a structure in which the drying section where the laundry is dried and the support section that supports the drying section can be folded and unfolded, so that the manufacturer can produce it and package and sell it in a folded state, or the user can fold it and store it when not in use.

[0003] However, although the area of ​​the clothes drying rack in the first direction (e.g., horizontal direction) is significantly smaller in the folded state than in the unfolded state, the difference in area between the folded and unfolded states in the other directions (e.g., vertical direction or height direction) is not large.

[0004] Therefore, even folded clothes drying racks are still packaged and sold in significant volume or area. This makes it difficult for consumers to transport the clothes drying racks in person or by vehicle when purchasing them offline. Online sales can also present challenges, such as delivery issues.

[0005] Alternatively, if a clothes drying rack is manufactured with an assembleable structure to reduce volume during packaging or sale, problems may arise such as difficulty in assembly or sturdiness or durability in the assembled state.

[0006] Accordingly, the present invention aims to provide an assembly-type clothes drying rack and its connecting members that can be used sturdily and stably while significantly reducing the volume or area of ​​product packaging and maximizing the convenience of assembly.

[0007] According to an embodiment of the present invention for solving the above technical problem, an assembly-type clothes drying rack comprises: a first pair of first main frame rods and a second pair of first main frame rods, a pair of main frame connecting members each connecting one end of one of the first main frame rods of the first pair to one end of one of the first main frame rods of the second pair; a pair of second main frame rods each connecting the other end of the first main frame rods of the first pair and the other end of the second main frame rods of the second pair via a corresponding main frame rod connecting member among the pair of main frame rod connecting members; a first pair of first support frame rods and a second pair of first support frame rods, each including an upper rod and a lower rod that are coupled to each other via separate upper and lower rod connecting members or a connecting structure formed by itself; A pair of support frame connecting members, each connecting one end of an upper rod of one of the first pair of first support frame rods with one end of an upper rod of one of the second pair of first support frame rods and connected to a corresponding main frame connecting member of the pair of main frame connecting members by a central member; A pair of second support frame rods, each connecting the other end of a lower rod of the first support frame rod of the first pair and the other end of a lower rod of the first support frame rod of the second pair via a corresponding support frame rod connecting member of the pair of support frame rod connecting members; And a pair of supporting parts, each including a pair of first supporting rods, a second supporting rod, a pair of first coupling heads positioned at one end of the pair of first supporting rods, a pair of second coupling heads positioned at both ends of the second supporting rod and connected to the pair of first coupling heads, and a pair of third coupling heads positioned at the other end of the pair of first supporting rods, supporting corresponding first main frame rods among the first pair and the second pair of first main frame rods;

[0059] Hereinafter, specific embodiments of the present invention will be described with reference to the drawings. The following detailed description is provided to facilitate a comprehensive understanding of the methods, devices, and / or systems described herein. However, these are merely examples and the present invention is not limited thereto.

[0060] In describing embodiments of the present invention, detailed descriptions of known technologies related to the present invention will be omitted if they are deemed to unnecessarily obscure the gist of the invention. Furthermore, the terms described below are defined based on their functions in the present invention and may vary depending on the intent or custom of the user or operator. Therefore, their definitions should be based on the overall content of this specification.

[0061] The terminology used in the detailed description is for the purpose of describing embodiments of the present invention only and is not intended to be limiting. Unless expressly stated otherwise, singular forms include plural references. In this description, the terms "comprises" or "having" are intended to indicate certain features, numbers, steps, operations, elements, portions, or combinations thereof, and should not be construed to exclude the presence or possibility of one or more other features, numbers, steps, operations, elements, portions, or combinations thereof other than those described.

[0062] Directional terms such as upper, lower, one side, other side, etc. are used in connection with the orientation of the disclosed drawings. Since the components of the embodiments of the present invention can be positioned in various orientations, the directional terms are used for illustrative purposes and not for limitation. In this case, the X-axis, Y-axis, and Z-axis of FIG. 1 can be one reference, and unless otherwise stated, the orientation of each component in other drawings is also described based on the same reference as the coordinate axes of FIG. 1.

[0063] While terms like "first" and "second" may be used to describe various components, these components should not be limited by these terms. These terms may be used to distinguish one component from another. For example, without departing from the scope of the present invention, a first component could be referred to as a "second component," and similarly, a second component could also be referred to as a "first component."

[0064] Additionally, unless otherwise stated, the description of the shape or position of each component of the assembled clothes drying rack according to the embodiment of the present invention is based on the state in which each component is combined and unfolded.

[0065] Figure 1 is an exploded view showing an assembly-type clothes drying rack according to an embodiment of the present invention.

[0066] Referring to FIG. 1, an assembly-type clothes drying rack (100) according to an embodiment of the present invention includes a drying unit (120), a support unit (140), a fixing unit (160), a support unit (180), and first to sixth connecting members (CNT1) to (CNT6).

[0067] The drying unit (120) includes a pair of main frames (122) that are spread out in a first direction (X-axis direction) and a plurality of drying rods (124) that are positioned spaced apart from each other in a space spaced apart from the pair of main frames (122) in a second direction (Y-axis direction). The pair of main frames (122) can form a “V” or “ㅡ” shape together when spread out at a certain angle. The pair of main frames (122) can be connected to each other through a first connecting member (CNT1). The first connecting member (CNT1) may also be referred to as a main frame connecting member.

[0068] The support member (140) includes a pair of support frames (142) that are spread out in the X-axis direction and support the drying member (120) in a third direction (Z-axis direction). The pair of support frames (142) can form a “V” shape that is rotated 180 degrees together when spread out at a certain angle. The pair of support frames (142) can be connected to each other via a second connecting member (CNT2). The second connecting member (CNT2) may be referred to as a support frame connecting member. Alternatively, the first connecting member (CNT1) and the second connecting member (CNT2) may be referred to together as a frame connecting member.

[0069] The second connecting member (CNT2) may be formed integrally with the first connecting member (CNT1) or may be formed separately from the first connecting member (CNT1).

[0070] A first connecting member (CNT1) coupled with a pair of main frames (122) and a second connecting member (CNT2) coupled with a pair of support frames (142) may be coupled to each other via a third connecting member (CNT3). The third connecting member (CNT3) may be referred to as a center member. The third connecting member (CNT3) may be formed integrally with at least one of the first connecting member (CNT1) and the second connecting member (CNT2), or may be formed separately from at least one of the first connecting member (CNT1) and the second connecting member (CNT2).

[0071] The first connecting member (CNT1) to the third connecting member (CNT3) can rotate within a certain angular range based on their fixed axes by themselves or through a separate hinge member (not shown). Accordingly, a pair of main frames (122) and a pair of support frames (142) connected to the first connecting member (CNT1) to the third connecting member (CNT3) can rotate within the corresponding angular range, so that the drying section (120) and the support section (140) of the assembly-type clothes drying rack (100) according to the embodiment of the present invention can be folded or unfolded. A more detailed description of the first connecting member (CNT1) to the third connecting member (CNT3) will be described later.

[0072] Continuing with reference to FIG. 1, a pair of main frames (122) according to an embodiment of the present invention may each include a pair of first main frame rods (122-1), a second main frame rod (122-2), and a pair of fourth connecting members (CNT4). A pair of first main frame rods (122-1) included in one of the pair of main frames (122) may be referred to as a first pair of first main frame rods (122-1), and a pair of first main frame rods (122-1) included in the other main frame (122) may be referred to as a second pair of first main frame rods (122-1). However, since the first main frame rods (122-1) of the first pair and the second pair are provided with the same structure, the following description of the first main frame rod (122-1) can be applied to both the first main frame rods (122-1) of the first pair and the second pair.

[0073] The fourth connecting member (CNT4) may be referred to as a main frame rod connecting member. A pair of first main frame rods (122-1) may be positioned parallel and spaced apart in the Y-axis direction, and a second main frame rod (122-2) may be connected so as to be orthogonal to the pair of first main frame rods (122-1) in a plane formed by the X-axis and the Y-axis. The pair of first main frame rods (122-1) and the second main frame rod (122-2) are connected by a pair of fourth connecting members (CNT4).

[0074] A pair of support frames (142) according to an embodiment of the present invention may each include a pair of first support frame rods (142-1), a second support frame rod (142-2), and a pair of fifth connecting members (CNT5). A pair of first support frame rods (142-1) included in one of the pair of support frames (142) may be referred to as a first pair of first support frame rods (142-1), and a pair of first support frame rods (142-1) included in the other support frame (142) may be referred to as a second pair of first support frame rods (142-1). However, since the first pair and the second pair of first support frame rods (142-1) are provided with the same structure, the following description of the first support frame rod (142-1) may be applied to both the first pair and the second pair of first support frame rods (142-1).

[0075] The fifth connecting member (CNT5) may be referred to as a support frame rod connecting member. Alternatively, the fourth connecting member (CNT4) and the fifth connecting member (CNT5) may be referred to together as a frame rod connecting member.

[0076] A pair of first support frame rods (142-1) may be positioned parallel and spaced apart in the Y-axis direction, and a second support frame rod (142-2) may be coupled so as to be orthogonal to the pair of first support frame rods (142-1) in a plane formed by the X-axis and the Y-axis. The pair of first support frame rods (142-1) and the second support frame rod (142-2) are coupled by a pair of fifth connecting members (CNT5).

[0077] At this time, a pair of first support frame rods (142-1) can be separated into an upper rod (UR) and a lower rod (DR), respectively. A more detailed description of the joining and separation of the upper rod (UR) and the lower rod (DR) constituting the first support frame rod (142-1) will be described later.

[0078] According to an embodiment of the present invention, button-type connecting members (BCMs) are mounted on both ends of the first main frame rod (122-1) and the first support frame rod (142-1).

[0079] FIG. 2 is a drawing showing a button-type coupling member according to an embodiment of the present invention mounted on a first main frame rod or a first support frame rod, FIG. 3 is a drawing showing a button-type coupling member according to an embodiment of the present invention in more detail, and FIG. 4 is a drawing showing the coupling of a button-type coupling member and a corresponding connecting member according to an embodiment of the present invention.

[0080] Referring to FIGS. 1 to 4, button-type coupling members (BCMs) are mounted on both ends of the first main frame rod (122-1) and the first support frame rod (142-1), respectively.

[0081] A button-type connecting member (BCM) mounted on one end of the first main frame rod (122-1) is button-type connected to the first connecting member (CNT1), and a button-type connecting member (BCM) mounted on the other end of the first main frame rod (122-1) is button-type connected to the fourth connecting member (CNT4) (Fig. 2 (a)).

[0082] As described above, since the first support frame rod (142-1) is separated into an upper rod (UR) and a lower rod (DR), a button-type connecting member (BCM) can be mounted on one end of the upper rod (UR) and the other end of the lower rod (DR), respectively. The button-type connecting member (BCM) mounted on one end of the upper rod (UR) is button-type connected with the second connecting member (CNT2), and the button-type connecting member (BCM) mounted on the other end of the lower rod (DR) is button-type connected with the fifth connecting member (CNT5).

[0083] In this way, by connecting both sides of the first main frame rod (122-1) and the first support frame rod (142-1) in a button-type manner, the convenience and sturdiness of the connection can be greatly improved. A more detailed description of the structure and method of the button-type connection according to an embodiment of the present invention will be described below.

[0084] The upper rod (UR) and the lower rod (DR), which are provided separately, can be connected to each other by separate upper and lower rod connecting members, or can be connected to each other through a connecting structure formed integrally with the upper rod (UR) or the lower rod (DR). Fig. 2 (b) illustrates an example in which a screw groove is formed on the other end of the upper rod (UR) and a screw thread corresponding to the screw groove of the upper rod (UR) is formed on one end of the lower rod (DR), so that the upper rod (UR) and the lower rod (DR) are connected in a screw manner. However, the present invention is not limited thereto. A more detailed description of the connection of the upper rod (UR) and the lower rod (DR) will be described later.

[0085] A button-type connecting member (BCM) includes an insertion portion (IU) inserted into a first main frame rod (122-1) or a first support frame rod (142-1) and a connecting portion (CU) formed such that one end thereof is in contact with the insertion portion (IU) and connected to a corresponding connecting member. The insertion portion (IU) and the connecting portion (CU) may be formed integrally. In this case, the corresponding connecting member (CNT) may be one of the first connecting member (CNT1), the second connecting member (CNT2), the fourth connecting member (CNT4), and the fifth connecting member (CNT5), but FIG. 4 illustrates an example in which the button-type connecting member (BCM) is connected to the fourth connecting member (CNT4) or the fifth connecting member (CNT5). An example in which the button-type connecting member (BCM) is connected to the first connecting member (CNT1) or the second connecting member (CNT2) will be described later.

[0086] The outer diameter of the insertion portion (IU) may be formed to be the same as the inner diameter of the first main frame rod (122-1) or the first support frame rod (142-1). The outer diameter of the joining portion (CU) may be formed to be the same as the outer diameter of the first main frame rod (122-1) or the first support frame rod (142-1).

[0087] The connecting portion (CU) includes a connecting button (CB) formed by protruding from its outer surface and a part of the outer periphery of the connecting button (CB), and a first cutting line (CL1) formed by cutting the outer surface so that the two ends are not connected to each other. In this case, including a part of the outer periphery of the connecting button (CB) may mean that it is formed by contacting a part of the outer periphery. However, it is not limited thereto, and the first cutting line (CL1) may be cut adjacent to a part of the outer periphery depending on the shape of the part of the outer periphery. The part of the outer periphery of the connecting portion (CU) where the connecting button (CB) is located and surrounded by the first cutting line (CL1) is referred to as an elastic piece (EP). The connecting portion (CU) may be implemented with a plastic or metal material having an arbitrary elastic coefficient.

[0088] When the connecting portion (CU) is inserted into the corresponding connecting member, force is applied in the insertion direction to the connecting button (CB) protruding from the outer surface of the connecting portion (CU). At this time, the other end of the connecting portion (CU) spaced apart from the insertion portion (IU) is formed to be rounded in the direction in which its outer diameter decreases, so that insertion into the inside of the corresponding connecting member (CNT) or separation from the inside of the corresponding connecting member (CNT) can be facilitated.

[0089] The force applied to the coupling button (CB) is distributed to the elastic piece (EP), so that the elastic piece (EP) can be sunk into the inner space of the coupling portion (CU). At this time, the elastic piece (EP) can be maintained connected to the outer surface of the coupling portion (CU) by the non-connected ends of the first cutting line (CL1).

[0090] As the elastic piece (EP) is sunk into the inner space of the connecting portion (CU), the protruding connecting button (CB) located on the elastic piece (EP) can be inserted into the inner side of the corresponding connecting member (CNT). At this time, since the corners of the connecting button (CB) are formed to be rounded, the connecting portion (CU) can be more easily inserted into the inner side of the corresponding connecting member (CNT) or separated from the inner side of the corresponding connecting member (CNT). When the connecting button (CB) is pulled out through the inner space of the corresponding connecting member (CNT) to the connecting hole (CH) by a pushing force, the elastic piece (EP) can return to its original position, i.e., on the same plane as the outer surface of the connecting portion (CU).

[0091] By pulling out the coupling button (CB) into the coupling hole (CH), the coupling of the first main frame rod (122-1) or the first support frame rod (142-1) and the corresponding coupling member (CNT) through the button-type coupling member (BCM) can be completed. When separating from the corresponding coupling member (CNT), the coupling button (CB) can be pressed and force applied in the opposite direction of the insertion direction so that the coupling button (CB) is inserted into the inside of the corresponding coupling member (CNT), thereby separating.

[0092] The button-type coupling member (BCM) according to an embodiment of the present invention is illustrated as an example in which the coupling button (CB) is formed in a rounded square shape and the first cut line (CL1) or elastic piece (EP) is formed in the shape of a fingertip joint, but is not limited thereto. The coupling button (CB) may be formed in the shape of a triangle, an inverted triangle, a pentagon, a hexagon, an ellipse, or a star, and the first cut line (CL1) may be formed in a shape corresponding to the outer periphery of the coupling button (CB) it includes. In this case, the first cut line (CL1) may be formed to include at least 1 / 2 or 2 / 3 or more of the entire outer periphery of the coupling button (CB). The elastic piece (EP) may be formed to correspond to the shape of the coupling button (CB) like the first cut line (CL1), or may be formed regardless of the shape of the coupling button (CB).

[0093] Preferably, the coupling portion (CU) of the button-type coupling member (BCM) according to an embodiment of the present invention may further include one or a pair of second cutting lines (CL2). The second cutting lines (CL2) are formed by cutting the outer circumference from the other end of the coupling portion (CU). When provided with a pair of second cutting lines (CL2), the pair of second cutting lines (CL2) may be positioned symmetrically with respect to the coupling button (CB). The second cutting lines (CL2) may be coupled with the coupling wall (CW) of the corresponding coupling member (CNT) to further strengthen the coupling between the button-type coupling member (BCM) and the corresponding coupling member (CNT).

[0094] In this way, the first main frame rod (122-1) and the first support frame rod (142-1) according to the embodiment of the present invention can be easily assembled and made sturdy by being equipped with button-type connecting members (BCM) at both ends. At this time, in order to easily and firmly connect with the button-type connecting member (BCM), the connecting members according to the embodiment of the present invention are provided with a structure corresponding to the button-type connecting member (BCM). This will be described below.

[0095] FIG. 5 is a drawing showing a fourth connecting member according to an embodiment of the present invention in more detail.

[0096] Referring to FIGS. 1, 4, and 5, the fourth connecting member (CNT4) may include a fourth body (BD4) and a fourth coupling groove (CG4). The fourth body (BD4), into which a button-type coupling member (BCM) mounted on the first main frame rod (122-1) is inserted and coupled, may be formed with one end of its interior open and the other end closed.

[0097] On the outer surface of the fourth body (BD4), a coupling hole (CH) corresponding to a coupling button (CB) of a button-type coupling member (BCM) is formed open. As described above, when the first main frame rod (122-1), i.e., the button-type coupling member (BCM), is coupled with the fourth connecting member (CNT4), the coupling button (CB) is pulled out from the coupling hole (CH) and positioned.

[0098] The internal space of the fourth body (BD4) may be formed in a shape corresponding to the shape of the first main frame rod (122-1) or the button-type coupling member (BCM), for example, in a cylindrical shape. Unless otherwise stated, it is assumed that each frame or rod, etc. according to the embodiment of the present invention is provided in the shape of a circular pipe, and therefore, the members coupled to each frame or rod will also be provided in a shape corresponding to a cylinder. However, each frame or rod, etc. according to the embodiment of the present invention may be provided in the shape of a square pillar, etc., and in that case, the members coupled to the frame or rod may also be provided in a shape corresponding to a square pillar, etc.

[0099] The inner diameter of the fourth body (BD4) can be reduced stepwise at least once from the other end. Fig. 5 (b) illustrates an example in which the inner diameter of the fourth body (BD4) is reduced once from the first inner diameter (id1) to the second inner diameter (id2). By reducing the inner diameter of the fourth body (BD4) stepwise, the joint portion (CU) of the button-type joint member (BCM) inserted into the fourth body (BD4) can be positioned more firmly.

[0100] The inner space of the fourth body (BD4) may further include a joining wall (CW) protruding from the inner wall thereof. As described above, the joining wall (CW) is joined to the second cut line (CL2) of the button-type joining member (BCM).

[0101] The outer side of the closed end of the fourth body (BD4) is formed round to ensure convenience and stability in use.

[0102] The fourth coupling groove (CG4) may be formed by protruding from the outside near the other end of the fourth body (BD4), and having one end open and the other end closed by the fourth body (BD4) within it. However, this is not limited thereto. The fourth body (BD4) and the fourth coupling groove (CG4) may be formed integrally, so that the other end of the fourth coupling groove (CG4) is not closed and its internal space may be connected to the internal space of the fourth body (BD4).

[0103] A second main frame rod (122-2) can be inserted and mounted into the internal space of the fourth coupling groove (CG4). The internal space of the fourth coupling groove (CG4) can be formed in a shape corresponding to the shape of the second main frame rod (122-2), for example, in a cylindrical shape.

[0104] In this way, the assembly-type clothes drying rack (100) according to the embodiment of the present invention optimizes the structures of the first main frame rod (122-1) and the second main frame rod (122-2), the button-type connecting member (BCM), and the fourth connecting member (CNT4), thereby minimizing the volume, weight, and parts while ensuring ease of assembly and sturdiness after assembly.

[0105] At this time, the second main frame rod (122-2) according to the embodiment of the present invention may also be equipped with button-type coupling members (BCM) at both ends thereof, similar to the first main frame rod (122-1). In this case, the fourth coupling groove (CG4) may include a coupling hole (CH) or a coupling wall (CW), similar to the fourth body (BD4).

[0106] In addition, the fourth connecting member (CNT4) according to an embodiment of the present invention may adopt various structures to further strengthen the connection between the first main frame rod (122-1) and the second main frame rod (122-2), or the button-type connecting member (BCM). For example, a fourth reinforcing member (RM4) may be provided at the connection portion between the fourth body (BD4) and the fourth connecting groove (CG4) to support or distribute the load resulting from the connection.

[0107] The description of the fourth connecting member (CNT4) above can be equally applied to the fifth connecting member (CNT5), and the description of the connection of the fourth connecting member (CNT4) with the first main frame rod (122-1) and the second main frame rod (122-2), or the button-type connecting member (BCM) can be equally applied to the connection of the fifth connecting member (CNT5) with the first support frame rod (142-1) and the second support frame rod (142-2), or the button-type connecting member (BCM).

[0108] FIG. 6 is a drawing showing the first to third connecting members according to an embodiment of the present invention, and FIG. 7 is a drawing for explaining the connection between the first to third connecting members and a button-type connecting member.

[0109] Referring to FIGS. 1, 6, and 7, a first connecting member (CNT1) according to an embodiment of the present invention may include a pair of first coupling plates (CP1) and a pair of first bodies (BD1). A first through hole (TH1) is formed at the center of each first coupling plate (CP1), and each first body (BD1) may be formed to be connected to a corresponding first coupling plate (CP1). A button-type coupling member (BCM) mounted on one end of a first main frame rod (122_1) is inserted and coupled into an open end of the first body (BD1). Accordingly, the internal space of each first body (BD1) may be formed in a shape corresponding to the shape of the coupling portion (CU) of the button-type coupling member (BCM), for example, a cylindrical shape.

[0110] The second connecting member (CNT2) may also be provided in the same shape as the first connecting member (CNT1). That is, the second connecting member (CNT2) may include a pair of second connecting plates (CP2) having a second through hole (TH2) formed in the center thereof, and a second body (BD2) connected to the second connecting plate (CP2) and having a cylindrical internal space formed therein. The diameters of the first through hole (TH1) and the second through hole (TH2) may be the same. A button-type connecting member (BCM) mounted on one end of the first support frame rod (142_1) is inserted into and connected to the open end of the second body (BD2).

[0111] The connection between the first body (BD1) of the first connecting member (CNT1) and the button-type connecting member (BCM) mounted on one end of the first main frame rod (122_1) is the same in technical concept as the connection between the fourth body (BD4) of the fourth connecting member (CNT4) described above and the button-type connecting member (BCM) mounted on the other end of the first main frame rod (122_1), and the connection between the second body (BD2) of the second connecting member (CNT2) and the button-type connecting member (BCM) mounted on the other end of the first support frame rod (142_1).

[0112] That is, a coupling hole (CH) corresponding to a coupling button (CB) of a button-type coupling member (BCM) is formed openly on the outer surface of the first body (BD1), so that when the button-type coupling member (BCM) mounted on one end of the first main frame rod (142-1) is coupled with the first body (BD1), the coupling button (CB) is pulled out from the coupling hole (CH) and positioned. In addition, the inner diameter of the first body (BD1) is reduced in a stepwise manner at least once on the other end side so that the coupling portion (CU) of the button-type coupling member (BCM) can be positioned more firmly. Furthermore, the inner space of the first body (BD1) further includes a coupling wall (CW) protruding from the inner wall thereof so as to be coupled with a second cut line (CL2) of the button-type coupling member (BCM).

[0113] However, unlike the fourth body (BD4), the shape of one end of the first body (BD1) will be formed into a shape suitable for connection with the first connecting plate (CP1). The second body (BD2) may be formed into the same shape as the first body (BD1).

[0114] The first connecting member (CNT1) and the second connecting member (CNT2) can be connected via a third connecting member (CNT3).

[0115] A pair of first connecting plates (CP1) of a first connecting member (CNT1) and a pair of second connecting plates (CP2) of a second connecting member (CNT2) overlap each other so that a first through hole (TH1) and a second through hole (TH2) are positioned at the same position, and a center rod (CR) is mounted on one side of the overlapped first through hole (TH1) and second through hole (TH2), and a third connecting member (CNT3) can be mounted on the other side. The first connecting member (CNT1) and the second connecting member (CNT2) connected through the third connecting member (CNT3) are provided as a pair, and the center rod (CR) connects between the pair of connecting members, thereby improving the sturdiness of the assembly-type clothes drying rack (100) according to an embodiment of the present invention.

[0116] The third connecting member (CNT3) may include a connecting hook (CK) and a fixing screw (FS). The connecting hook (CK) may be first inserted into the inner side of the center rod (CR) in the area where the first through hole (TH1), the second through hole (TH2), and the center rod (CR) overlap, and then the fixing screw (FS) may be inserted into the connecting hook (CK) and mounted.

[0117] Through this structure, the first connecting member (CNT1) and the second connecting member (CNT2) can be rotated, so that the drying unit (120) and the support unit (140) can be used in a foldable manner. In addition, a part of the side of the connecting hook (CK) is cut off and a protruding groove is formed on the inside, so that when the fixing screw (FS) is mounted on the connecting hook (CK), the center rod (CR) is pressed so that it is more closely attached to the first through hole (TH1) and the second through hole (TH2), thereby firmly connecting the first connecting member (CNT1) to the third connecting member (CNT3).

[0118] At this time, a through-hole coupling tube (TP) may be further provided to further strengthen the connection. The through-hole coupling tube (TP) is mounted within the overlapping first through-hole (TH1) and second through-hole (TH2), and a center rod (CR) may be inserted into the interior thereof.

[0119] In addition, when the first connecting member (CNT1) and the second connecting member (CNT2) limit the rotation angle, the support member (140) of the assembly-type clothes drying rack (100) according to the embodiment of the present invention may be fixed without being spread out beyond a certain angle even without including a separate fixing member (160).

[0120] Referring again to FIG. 1, the fixing member (160) connects a pair of support frames (142) of the support member (140) to each other to fix the movement of the support member (140).

[0121] FIG. 8 is a drawing showing another second connecting member according to another embodiment of the present invention.

[0122] Referring to FIGS. 6 and 8, the first connecting member (CNT1) and the third connecting member (CNT3) of FIG. 8 may be provided in the same manner as in FIG. 6. On the other hand, unlike the second connecting member (CNT2) of FIG. 6 which is provided in the same shape as the first connecting member (CNT1), the second connecting member (CNT2) of FIG. 8 may be provided in a different shape from the first connecting member (CNT1).

[0123] For example, the second body (BD2) of the second connecting member (CNT2) of FIG. 8 may be provided longer than the first body (BD1) of the first connecting member (CNT1). The second body (BD2) may be provided with at least one first open area (OA1) that is cut open to reduce the weight of the second connecting member (CNT2). At least one mounting hook (HK) may also be provided at the other end of the second body (BD2).

[0124] Figure 9 is an enlarged view of the mounting hook of Figure 8.

[0125] Referring to FIGS. 8 and 9, a mounting hook (HK) according to an embodiment of the present invention may include a mounting plate (HS) and a support plate (SS). The mounting plate (HS) may be formed to protrude and extend from the second body (BD2) and have the other end spaced apart from the second body (BD2) bent toward the second coupling plate (CP2) to form an open space. The support plate (SS) may also be formed to protrude from the second body (BD2) and have the other end spaced apart from the second body (BD2) bent toward the second coupling plate (CP2), and the other end may be formed to be in contact with the mounting plate (HS). The support plate (SS) may be formed to have a shape in which the side surface is closed or open. FIG. 9 illustrates an example in which the support plate (SS) located closest to the other end is opened.

[0126] A support member (180) may be mounted on the mounting hook (HK). For example, the support member (180) may be mounted by having both ends formed by bending and shorting penetrate the open side of the support plate (SS). The support member (180) may be provided as a frame having a shape that is bent at least twice between the both ends formed by bending and shorting. The drying bar (124) of FIG. 1 may be mounted on the bent portion formed between the both ends of the support member (180). However, the support member (180) may be provided differently. Further details regarding this will be described later.

[0127] FIG. 10 is a drawing showing a frame connecting member according to an embodiment of the present invention.

[0128] Referring to FIGS. 6 and 10, a frame connecting member (CNTF) according to an embodiment of the present invention may include a first connecting member (CNT1) and a second connecting member (CNT2) that are formed integrally. For example, a first connecting plate (CP1) of the first connecting member (CNT1) and a second connecting plate (CP2) of the second connecting member (CNT2) may be formed integrally. A first body (BD1) of the first connecting member (CNT1) and a second body (BD2) of the second connecting member (CNT2) may be connected to a first main frame rod (122_1) and a first support frame rod (142_1), respectively, by a button-type connecting member (BCM).

[0129] The second body (BD2) may be provided with the same structure as in Fig. 8. That is, the second body (BD2) may be provided with at least one first open area (OA1) that is cut open, and at least one mounting hook (HK) may be provided at the other end. In addition, the mounting hook (HK) may include a mounting plate (HS) and a support plate (SS).

[0130] Fig. 11 is a drawing showing an example of a stand being attached to the assembly-type clothes drying rack of Fig. 10.

[0131] Referring to FIGS. 10 and 11, the support member (180) according to an embodiment of the present invention may be provided as a frame having a shape that is bent at least twice between the two ends formed by bending and short-circuiting. At this time, unlike FIGS. 8 and 9, the two ends of the mounting hook (HK) that are bent and short-circuited may be mounted by penetrating the first body hole (BH1) formed in the first body (BD1), and the folded portion formed between the two ends of the support member (180) may be mounted in an open space formed by bending the mounting plate (HS). However, the support member (180) may be provided differently. This will be described in more detail later.

[0132] Figures 12 and 13 are drawings showing a fixing part according to an embodiment of the present invention, respectively.

[0133] First, referring to FIG. 1 and FIG. 12, a fixing member (160) according to an embodiment of the present invention may include a pair of fixing frames (162) and a pair of fixing rods (164).

[0134] An open frame penetration hole (FTH) may be formed at both ends on the inside of each fixed frame (162). In addition, the middle portion of each fixed frame (162) may be formed to be foldable, i.e., foldable, so that the assembled clothes drying rack (100) according to the embodiment of the present invention can be folded together when the assembly is completed.

[0135] A pair of fixing rods (164) may be installed by passing through the frame penetration holes (FTH), respectively. Each fixing rod (164) may be provided with a length corresponding to the distance (sd) between a pair of first support frame rods (142-1) positioned spaced apart in the Y-axis direction when the assembly-type clothes drying rack (100) according to an embodiment of the present invention is assembled.

[0136] The fixing member (160) according to an embodiment of the present invention can assist the function of the drying member (120) in addition to fixing the separation distance of a pair of support frames (142). To this end, the fixing member (160) according to an embodiment of the present invention can further include a plurality of auxiliary drying rod coupling grooves (166) and a plurality of auxiliary drying rods (168). The auxiliary drying rod coupling grooves (166) can be formed on the inside of the fixing frame (162). In this case, the auxiliary drying rods (168) are provided with a length corresponding to the separation distance in the Y-axis direction of the pair of fixing frames (162), and thus can be shorter than the fixing rods (164).

[0137] Next, referring to FIGS. 1 and 13, similarly to FIG. 12, the fixed part (160) may support the assembled support frame (142) including the fixed frame (162) and the fixed rod (164), while assisting the function of the drying part (120). However, unlike FIG. 12, the fixed frame (162) of FIG. 13 may not have the fixed rod (164) installed by penetrating the frame through hole (FTH) of the fixed frame (162). Instead of the frame through hole (FTH) being formed in the fixed frame (162), the fixed part (160) of FIG. 13 may have a fixed rod mounting groove (FG) formed therein. The fixed rod (164) may be inserted into the opening of the fixed rod mounting groove (FG) and installed in the inner space of the fixed rod mounting groove (FG).

[0138] At this time, the diameter of the opening of the fixed rod mounting groove (FG) may be formed to be smaller than the diameter of the fixed rod (164). The fixed rod (164) may not be detached after being inserted into the fixed rod mounting groove (FG) due to the elasticity of the fixed frame (162). Accordingly, the fixed rod (164) may be more easily coupled to the fixed frame (162) while maintaining a firm state.

[0139] Although (a) and (b) of FIG. 13 illustrate examples in which the opening of the fixed rod mounting groove (FG) is formed downward, the present invention is not limited thereto. As illustrated in (c) of FIG. 13, the opening of the fixed rod mounting groove (FG) may be formed in both lateral directions. Alternatively, as illustrated in (d) of FIG. 13, the fixed rod mounting groove (FG) may include two internal spaces having different diameters. Accordingly, even if the diameter of the fixed rod (164) varies depending on the size of the assembly-type clothes drying rack (100) according to the embodiment of the present invention, the same fixed frame (162) can be used, thereby simplifying the production process. Alternatively, in the case of FIG. 13 (d), the fixed rod (164) is mounted in the internal space located apart from the opening, thereby making the connection between the fixed frame (162) and the fixed rod (164) more solid.

[0140] Referring back to FIG. 1, the supporting member (180) is provided in a pair and connects a corresponding support frame (142) and any one of a plurality of drying rods (124). Depending on the position of the drying rod (124) to which the supporting member (180) is connected, the angle that the drying member (120) forms with the plane formed by the X-axis and the Y-axis may vary.

[0141] Fig. 14 is a drawing showing a support part according to an embodiment of the present invention.

[0142] Referring to FIGS. 1 and 14, a support member (180) according to an embodiment of the present invention may include an upper frame (182) and a lower frame (184). The upper frame (182) and the lower frame (184) may each be provided in a “$” shape. Two corners of the upper frame (182) may be formed by being bent so that a drying rod (124) may be placed thereon. The upper frame (182) and the lower frame (184) may be foldably connected. For example, both ends of the upper frame (182) may be bent to form a ring, and the lower frame (184) may be inserted into the ring and connected. Both ends of the lower frame (184) may be formed by being bent.

[0143] At this time, the width (WD) of the lower frame (184) in the X-axis direction is longer than the separation distance (sd) in the Y-axis direction between the first support frame rods (142_1). Therefore, the lower frame (184) is supported by a pair of the first support frame rods (142_1), and the upper frame (182) connected to the lower frame (184) by the support force thereof can support the corresponding drying rod (124).

[0144] The structure of this support (180) allows for minimizing the volume and weight of the pre-assembled clothes drying rack (100) while ensuring its sturdiness after assembly, thereby enhancing ease of use. Furthermore, the support (180) according to an embodiment of the present invention can further reduce the volume and weight before assembly while maintaining sturdiness during installation and use. This will be described below.

[0145] FIG. 15 is a drawing showing a support according to another embodiment of the present invention, FIG. 16 is a drawing showing the first to third coupling heads of FIG. 15 in more detail, FIG. 17 is a drawing explaining an operation of coupling the first coupling head and the second coupling head, FIG. 18 is a drawing showing an assembly-type clothes drying rack having the support of FIG. 15, and FIG. 19 is an exploded view of the assembly-type clothes drying rack of FIG. 18.

[0146] Referring to FIGS. 15 to 19, the support member (180) according to the embodiment of the present invention is folded in a straight line shape before assembly, for example, during packaging or sale, but can be unfolded in a “ㄷ” shape during assembly or use. To this end, the support member (180) according to the embodiment of the present invention can support the first main frame rod (122-1) by including a pair of first support rods (SB1) and second support rods (SB2), and first to third coupling heads (CD1) to third coupling heads (CD3). The support members (180) can be provided as a pair to support two pairs of first main frame rods (122-1). The first coupling head (CD1) is positioned at one end of the first support rod (SB1), and the second coupling heads (CD2) are positioned at both ends of the second support rod (SB2).

[0147] The first coupling head (CD1) may include a first-first support rod coupling groove (SC1-1), a main frame support groove (MG), and a head coupling groove (HG). One end of the first support rod (SB1) may be inserted and mounted into the inner space of the first-first support rod coupling groove (SC1-1). The main frame support groove (MG) may include a support frame (SF) provided with a pair of first side walls (WL1) and a bottom surface (FP), and a support plate (SP) provided in contact with the inner side of the support frame (SF). One side of the support plate (SP) that does not contact the inner side of the support frame (SF) is etched into a semicircular shape, so that the first main frame rod (122-1) having a cylindrical shape may be inserted into the main frame support groove (MG) and mounted on the support plate (SP). However, the present invention is not limited thereto. The shape of one side of the support plate (SP) may vary depending on the shape of the first main frame rod (122-1), and the shape may be formed by a method other than etching.

[0148] The head engaging groove (HG) may include a pair of second side walls (WL2), a first protrusion (BP1), and a second protrusion (BP2). The second side walls (WL2) may be provided so as to contact both sides of the first side walls (WL1) of the support frame (SF) and extend in a direction parallel to the bottom surface (FP). The first protrusion (BP1) may be provided so as to protrude in a direction in which the second side wall (WL2) extends from the first side wall (WL1) where the second side wall (WL2) is in contact.

[0149] The first protrusion (BP1) may include a first-first protrusion (BP1-1) and a first-second protrusion (BP1-2) having different protrusion lengths from the first side wall (WL1) and having their respective ends in contact with each other. The first-first protrusion (BP1-1) may be positioned further from the bottom surface (FP) than the first-second protrusion (BP1-2). At this time, the first-first protrusion (BP1-1) of the first protrusion (BP1) may be provided in the shape of a square pillar. In addition, one end of the first-second protrusion (BP1-2) may be provided in a shape in which the protrusion length from the first side wall (WL1) is further protruded from the first side wall (WL1) than the first-first protrusion (BP1-1), and the protrusion length from the first side wall (WL1) is reduced in the other end direction with the first curvature, so that the other end is in contact with the first side wall (WL1). For reference, when the first coupling head (CD1) is viewed from the front, the first protrusion (BP1) will be covered by the second side wall (WL2), but Fig. 17 illustrates a cross-section of the first protrusion (BP1) for convenience of explanation.

[0150] A pair of second protrusions (BP2) may be provided so as to protrude in a direction facing each other from each second side wall (WL2). Fig. 16 (a) illustrates an example in which the second protrusions (BP2) are provided in a cylindrical shape with a portion of the other end spaced apart from the second side wall (WL2) etched, but the present invention is not limited thereto.

[0151] The second coupling head (CD2) may include a second support rod coupling groove (SC2) and a head coupling plate (HP). A second support rod (SB2) may be inserted and mounted into the inner space of the second support rod coupling groove (SC2). The lower surface of the head coupling plate (HP) may be positioned in contact with the second support rod coupling groove (SC2), and a first groove (GR1) may be formed on the upper surface.

[0152] The first groove (GR1) may be provided with a recessed shape corresponding to the first protrusion (BP1). That is, the first groove (GR1) may include a first-first groove (GR1-1) and a first-second groove (GR1-2), each of which has one end in contact with the other. The first-first groove (GR1-1) may be provided with a recessed shape corresponding to the shape of the first-first protrusion (BP1-1), and the first-second groove (GR1-2) may be provided with a recessed shape corresponding to the shape of the first-second protrusion (BP1-2). Accordingly, when the first coupling head (CD1) and the second coupling head (CD2) are coupled and the first support rod (SB1) and the second support rod (SB2) are vertical ((c) of FIG. 17), the first-first projection (BP1-1) and the first-first groove (GR1-1) can be in contact, and the first-second projection (BP1-2) and the first-second groove (GR1-2) can be in contact. In addition, when the first support rod (SB1) and the second support rod (SB2) are vertical ((c) of FIG. 17), the area from the other end of the first-first groove (GR1-1) of the upper surface of the head coupling plate (HP) to one side of the head coupling plate (HP) can span the outer side of the other end of the first-first projection (BP1-1).

[0153] The other side of the head coupling plate (HP) may be provided with a curved surface having a second curvature from the other end of the first-second groove (GR1-2) to a point corresponding to the other end of the first-second projection (BP1-2) when the first coupling head (CD1) and the second coupling head (CD2) are coupled and the first support rod (SB1) and the second support rod (SB2) are horizontal (Fig. 17 (b)). At this time, the second curvature may be determined based on the first curvature of the first-second projection (BP1-2) and the length from the first-second groove (GR1-2) of the head coupling plate (HP) to the point corresponding to the other end of the first-second projection (BP1-2).

[0154] In the above, the first protrusion (BP1) and the first groove (GR1) are described as being divided into two regions, respectively. This is to ensure that the first support rod (SB1) and the second support rod (SB2) operate smoothly when unfolding from (b) of Fig. 17 to (c) of Fig. 17 or vice versa, while firmly maintaining the unfolded state as in (c) of Fig. 17, but is not limited thereto.

[0155] A second protrusion mounting hole (BBH) is provided through a head coupling plate (HP). When the first coupling head (CD1) and the second coupling head (CD2) are coupled, a pair of second protrusions (BP2) can be inserted and mounted into the second protrusion mounting hole (BBH). At this time, the head coupling plate (HP) may further include a second protrusion guide (BGD) that is etched and provided in the direction of the second protrusion mounting hole (BBH) from the other side. When the first coupling head (CD1) and the second coupling head (CD2) are coupled, a pair of second protrusions (BP2) can be inserted into the second protrusion mounting hole (BBH) along the second protrusion guide (BGD).

[0156] In this way, when the support member (180) according to the embodiment of the present invention is packaged and sold in a folded state as shown in (b) of FIG. 17, and then is installed on the assembly-type clothes drying rack (100) as shown in (a) of FIG. 18 in an unfolded state as shown in (c) of FIG. 17, or vice versa, when it is used in an unfolded state as shown in (c) of FIG. 17 and then stored in a folded state as shown in (b) of FIG. 17, the movement of the head coupling plate (HP) of the second coupling head (CD2) with respect to the head coupling groove (HG) of the first coupling head (CD1) can be smooth and the coupling force can be firm. In this way, while ensuring the sturdiness of the assembly-type clothes drying rack (100) according to the embodiment of the present invention, the volume of the assembly-type clothes drying rack (100), which may be limited by the support member (180), can be significantly reduced during packaging and sale.

[0157] The above description is limited to the coupling between the first coupling head (CD1) of one of a pair of first support rods (SB1) and the second coupling head (CD2) positioned at one end of the second support rod (SB2), but the same applies to the coupling between the first coupling head (CD1) of another first support rod (SB1) and the second coupling head (CD2) positioned at the other end of the second support rod (SB2).

[0158] Furthermore, the third coupling head (CD3) of the support member (180) according to the embodiment of the present invention may be positioned at the other end of a pair of first support rods (SB1). Each third coupling head (CD3) may include a first-second support rod coupling groove (SC1-2) and a fastening hook (FH). The other end of the first support rod (SB1) may be inserted into the first-second support rod coupling groove (SC1-2) and coupled. The fastening hook (FH) may be provided in a semi-cylindrical shape that is open in one direction. At this time, both ends of the fastening hook (FH) are bent to a certain extent in the outward direction to easily fasten to an object to be fastened, and after fastening, the coupling can be firmly fixed by elasticity.

[0159] FIG. 18(b), which explains the fastening operation of the dotted line portion of FIG. 18(a), illustrates an example in which the fixed frame (162) is connected to the fixed rod (164), and the fastening hook (FH) is fastened to the fixed part coupling groove (FXG) of the sixth connecting member (CNT6) connecting the support frame (142) and the fixed rod (164), but is not limited thereto. The fastening hook (FH) may also be fastened to the fixed rod (164) together with the fixed frame (162). The fixed part coupling groove (FXG) of the sixth connecting member (CNT6) will be described later. FIG. 20 is a drawing showing a drying unit according to an embodiment of the present invention, and FIG. 21 is a drawing showing the mounting member of FIG. 20 in more detail.

[0160] Referring to FIGS. 20 and 21, the drying unit (120) according to an embodiment of the present invention is formed in a structure in which laundry can be hung. At this time, in order to prevent a hole from being formed in the main frame (122) according to the embodiment of the present invention, the drying unit (120) of the present invention may be positioned between a plurality of drying rods (124) spaced apart from each other between the main frames (122) through a separate mounting member (MTM).

[0161] A plurality of drying rods (124) can be mounted on the mounting member (MTM). The mounting member (MTM) can include a pair of mounting frames (MF) and a plurality of drying rod coupling grooves (DG).

[0162] A pair of mounting frames (MF) are respectively coupled to corresponding first main frame rods (122-1). In order to increase the ease and stability of the coupling, the pair of mounting frames (MF) may be formed in a semi-cylindrical shape so that they can be coupled while wrapping around a certain portion of the first main frame rod (122-1). At this time, the mounting frame (MF) may be provided with at least one second open area (OA2) that is cut open to reduce weight. The second open area (OA2) may be formed in an area excluding the minimum area necessary for the mounting of the mounting frame (MF) to the first main frame rod (122-1) and the formation of a dry rod coupling groove (DG).

[0163] A plurality of drying rod coupling grooves (DG) may be formed to protrude from the outside of the mounting frame (MF). The plurality of drying rod coupling grooves (DG) may be formed to be spaced apart from each other at regular intervals in the X-axis direction on the side of the mounting frame (MF). One end of the drying rod (124) may be inserted into a first drying rod coupling groove (DG1) among the drying rod coupling grooves (DG) or may be separated from the first drying rod coupling groove (DG1). The other end of the drying rod (124) may be inserted into a second drying rod coupling groove (DG2) among the drying rod coupling grooves (DG) or may be separated from the second drying rod coupling groove (DG2).

[0164] Fig. 22 is a drawing showing the state of the connection of the upper and lower rods of Fig. 1 in more detail, and Fig. 23 is an exploded view of the connection of the upper and lower rods of Fig. 22.

[0165] Referring to FIGS. 1, 22, and 23, the first support frame rod (142-1) according to an embodiment of the present invention can be separated into an upper rod (UR) and a lower rod (DR). The upper rod (UR) and the lower rod (DR) can be connected via a connecting rod (CR). The connecting rod (CR) can be located on the inner side of the upper rod (UR) and the lower rod (DR). That is, the outer diameter of the connecting rod (CR) can be provided to be smaller than the inner diameters of the upper rod (UR) and the lower rod (DR). The position of the upper rod (UR), which is mounted in the direction of the arrow, can be fixed by the first fixing ring (FR1) of the connecting rod (CR). The first fixing ring (FR1) can be formed integrally with the connecting rod (CR). For example, the first fixed ring (FR1) is provided to protrude from the outer surface of the connecting rod (CR), and the outer diameter of the first fixed ring (FR1) may be larger than the outer diameters of the upper rod (UR) and the lower rod (DR).

[0166] Based on the first fixed ring (FR1), the lower part of the connecting rod (CR) can be inserted into the lower rod (DR), and the upper part of the connecting rod (CR) can be inserted into the upper rod (UR). In order to increase the bonding strength between the upper rod (UR) and the lower rod (DR), the connecting rod (CR) can be provided with at least one sub-ring (SR). The sub-ring (SR) can be provided with an elastic material such as a rubber ring. The sub-ring (SR) can be formed integrally with the connecting rod (CR) or can be provided separately and mounted on the connecting rod (CR).

[0167] The sub-ring (SR) can be mounted in the first sub-groove (SG1) formed on the outer surface of the connecting rod (CR). For convenience of explanation, Fig. 23 illustrates the first sub-groove (SG1) on the upper portion of the connecting rod (CR) without the sub-ring (SR) mounted thereon; however, the sub-ring (SR) can also be positioned in the first sub-groove (SG1) on the upper portion of the connecting rod (CR).

[0168] An integrated connecting member may be mounted on the outside of the upper rod (UR). At this time, the integrated connecting member may mean connecting two or more different types of configurations of the assembly-type clothes drying rack (100) according to an embodiment of the present invention. The integrated connecting member may be referred to as a sixth connecting member (CNT6). The position of the sixth connecting member (CNT6) in the direction of the arrow may be fixed by the first fixing ring (FR1). The sixth connecting member (CNT6) according to an embodiment of the present invention can be mounted without drilling holes in a frame or rod, etc., and can minimize the number and types of parts while making the combination easy and sturdy.

[0169] FIG. 24 is a drawing showing a sixth connecting member according to an embodiment of the present invention in more detail, and FIG. 25 is a drawing showing a connecting structure through the sixth connecting member according to an embodiment of the present invention.

[0170] Referring to FIGS. 24 and 25, a sixth connecting member (CNT6) according to an embodiment of the present invention may include a sixth body (BD6), a fixed portion coupling groove (FXG), and a pair of support portion coupling wings (SW). The fixed portion coupling groove (FXG) may be provided to protrude from the sixth body (BD6). A fixed rod (164) of a fixed portion (160) may be inserted and mounted into the fixed portion coupling groove (FXG).

[0171] A pair of support member coupling wings (SW) can be mounted by penetrating corresponding ends of the lower frame (184) of the support member (180), respectively. The pair of support member coupling wings (SW) can each include a sixth through hole (TH6) that protrudes from the outside of the sixth body (BD6) and is formed by penetrating the support member coupling wings (SW). The pair of support member coupling wings (SW) can be positioned symmetrically with respect to the fixed member coupling groove (FXG). Since the support member coupling wings (SW) are provided as a pair that is symmetrical with respect to the fixed member coupling groove (FXG), the sixth connecting member (CNT6) can be used for any of the four first support frame rods (142-1) even if the mounting positions thereof are different.

[0172] It is not limited to this. In the case where the support part (180) is provided in one stage as in Fig. 8 or Fig. 10 or the support part (180) is fastened through a fastening hook (FH) as in Fig. 15, the support part coupling wing (SW) may not be provided on the sixth connecting member (CNT6).

[0173] Fig. 26 is a drawing showing a state of coupling of an upper rod and a lower rod according to another embodiment of the present invention, and Fig. 27 is an exploded view of the coupling of the upper rod and the lower rod of Fig. 26.

[0174] Referring to FIGS. 26 and 27, one end of the lower rod (DR) can be formed and joined by being inserted into the inside of the upper rod (UR). At this time, the joining force between the upper rod (UR) and the lower rod (DR) can be increased through the sixth connecting member (CNT6).

[0175] The sixth body (BD6) of the sixth connecting member (CNT6) may include an outer body (OB) and an inner body (IB). The inner body (IB) may be provided shorter than the outer body (OB). An inner groove (IG) may be provided between the inner body (IB) and the outer body (OB). The inner groove (IG) may be provided with one end open and the other end closed. The sixth connecting member (CNT6) may not have the support portion engaging wing (SW) of FIG. 24 formed thereon.

[0176] The upper rod (UR) can be inserted into the inner groove (IG). A catch step (SJ) can be formed on the lower rod (DR) as the diameter of the end to be coupled with the upper rod (UR) is reduced. When the upper rod (UR) and the lower rod (DR) are coupled, the closed other end of the inner groove (IG) of the sixth connecting member (CNT6) can be positioned on the catch step (SJ). At least one second sub-groove (SG2) can be provided on the outer surface of one end of the lower rod (DR). When the upper rod (UR) and the lower rod (DR) are coupled, a concave projection (CPR) of the upper rod (UR) can be positioned in the second sub-groove (SG2). A coupling guide groove (CGG) can be formed from the second sub-groove (SG2) of the lower rod (DR) to one end. When the upper rod (UR) and the lower rod (DR) are coupled, the concave projection (CPR) of the upper rod (UR) can be positioned in the second sub-groove (SG2) along the coupling guide groove (CGG). FIG. 28 is a drawing showing a coupling state of the upper rod and the lower rod according to another embodiment of the present invention, and FIG. 29 is an exploded view of the coupling of the upper rod and the lower rod of FIG. 28.

[0177] Referring to FIGS. 28 and 29, one end of the lower rod (DR) may be formed by being inserted into the other end of the upper rod (UR). For this purpose, the diameter of one end of the lower rod (DR) may be smaller than the diameter of the upper rod (UR). On the other hand, in order to increase the bonding strength with the upper rod (UR), one end of the lower rod (DR) may be provided with the same structure as the lower end of the connecting rod (CR) of FIG. 23. That is, at least one sub-ring (SR) may be provided at one end of the lower rod (DR). The sub-ring (SR) may be provided with an elastic material such as a rubber ring. The sub-ring (SR) may be formed integrally with the lower rod (DR) or may be provided separately and mounted on the connecting rod (CR). The sub-ring (SR) may be mounted in a first sub-groove formed on the outer circumferential surface of the lower rod (CR). Although the first sub-home is not accurately depicted in Fig. 29 because it is covered by the sub-ring (SR) in the first sub-home, the first sub-home of Fig. 29 can be provided like the first sub-home (SG1) of Fig. 23.

[0178] At this time, the sixth connecting member (CNT6) can be fixed in position by the sixth fixing ring (FR6) by penetrating the upper rod (UR). In a state where the upper rod (UR) and the lower rod (DR) are connected, the sixth fixing ring (FR6) can be fixed in position by a catch jaw (SJ) formed by narrowing the diameter of the lower rod (DR).

[0179] Fig. 30 is a drawing showing a state of coupling of an upper rod and a lower rod according to another embodiment of the present invention.

[0180] Referring to FIG. 30, when the lower rod (DR) is inserted into the upper rod (UR) and coupled according to an embodiment of the present invention, a pair of protrusions (PR) of the lower rod (DR) may protrude outward from a coupling hole (not shown) of the upper rod (UR) so that the coupled state may be maintained. The protrusion member (PM) of the lower rod (DR) may be provided in a triangular pyramid shape in which the diameter of one end protruding outward from the lower rod (DR) is smaller than the diameter of the other end located inside the lower rod (DR). The non-protruding end of the protrusion member (PR) may be positioned to contact the side surface of the protrusion member (PM).

[0181] In the above embodiment, the upper rod (UR) and the lower rod (DR) are connected through separate upper and lower rod connecting members. However, the present invention is not limited thereto.

[0182] FIG. 31 is a drawing showing a state of coupling of an upper rod and a lower rod according to another embodiment of the present invention, and FIG. 32 is a cross-sectional view of (b) of FIG. 31 with a sixth connecting member mounted.

[0183] Referring to FIGS. 31 and 32, a concave projection (CPR) may be provided adjacent to the other end of the upper rod (UR) according to an embodiment of the present invention, and a second sub-groove (SG2), a coupling guide groove (CGG), and a catch step (SJ) may be provided at one end of the lower rod (DR). The concave projection (CPR) may protrude to a certain extent from the inner wall of the upper rod (UR), and the second sub-groove (SG2) and the coupling guide groove (CGG) may be provided to be recessed to a certain extent on the outer side of the lower rod (DR). The concave projection (CPR) and the second sub-groove (SG2) may be provided in two numbers each, but the present invention is not limited thereto. Accordingly, FIG. 31 illustrates an example in which the concave projection (CPR) and the second sub-groove (SG2) are provided in two numbers each, and FIG. 32 illustrates an example in which the concave projection (CPR) and the second sub-groove (SG2) are provided in one number each. When the concave projections (CPR) and the second sub-groove (SG2) are provided in two numbers each, the spacing between the pair of concave projections (CPR) and the spacing between the pair of second sub-grooves (SG2) are provided to be the same.

[0184] When the lower rod (DR) is inserted into the upper rod (UR), the concave projection (CPR) of the upper rod (UR) moves along the engagement guide groove (CGG) until the upper rod (UR) reaches the engaging shoulder (SJ) of the lower rod (DR). At this time, the upper rod (UR) or the lower rod (DR) is turned in a direction perpendicular to the direction in which the lower rod (DR) is inserted, so that the concave projection (CPR) of the upper rod (UR) is positioned in the second sub-groove (SG2) of the lower rod (DR). Thus, the engagement between the upper rod (UR) and the lower rod (DR) can be maintained.

[0185] The lower rod (DR) according to an embodiment of the present invention may further include a concave projection (CPR). At this time, the concave projections (CPR) of the upper rod (UR) and the lower rod (DR) are respectively positioned on the same line as the center of the engaging button (CB) of the button-type engaging member (BCM). Accordingly, after the upper rod (UR) reaches the catching step (SJ) of the lower rod (DR), the user can accurately position the button-type engaging member (BCM) connected to the upper rod (UR) and the lower rod (DR) by turning the upper rod (UR) or the lower rod (DR) so that the concave projections (CPR) of the upper rod (UR) and the lower rod (DR) are positioned on a straight line. Therefore, the assembly of the collapsible clothes drying rack (100) according to an embodiment of the present invention can be accurately performed.

[0186] The sixth connecting member (CNT6) can be mounted on the combined upper rod (UR) and lower rod (DR). The combined upper rod (UR) and lower rod (DR) are inserted into the inner side of the sixth body (BD6) of the sixth connecting member (CNT6), and a catch projection (SPR) formed by protruding from the inner wall of the sixth body (BD6) can be positioned and fixed on the catch step (SJ). Although not shown in Fig. 32, a catch joining groove (FXG) is formed in the sixth connecting member (CNT6) as in Fig. 24. Through the sixth connecting member (CNT6), the catch (160) of Fig. 1 can be integrally coupled to the support frame (142).

[0187] Referring again to FIG. 1, in the assembly-type clothes drying rack (100) according to the embodiment of the present invention, button-type connecting members (BCM) may be provided at both ends of the first main frame rod (122-1), one end of the upper rod (UR) of the first support frame rod (142-1), and the other end of the lower rod (DR) of the first support frame rod (142-1). However, this is not limited thereto.

[0188] Figures 33 and 34 are exploded views and joint views, respectively, showing the connection relationship between a connecting member and a frame rod according to another embodiment of the present invention.

[0189] Referring to FIGS. 1, 33, and 34, in the assembly-type clothes drying rack (100) according to an embodiment of the present invention, a connecting member (CNT) and a frame rod (FR) can be connected by a rod connection hook (RH). The connecting member (CNT) can be the first connecting member (CNT1), the second connecting member (CNT2), the fourth connecting member (CNT4), or the fifth connecting member (CNT5) described above. The frame rod (FR) can be at least one of the upper rod (UR) or the lower rod (DR) of the first main frame rod (122-1), the first support frame rod (142-1).

[0190] The rod coupling hook (RH) can be inserted into the inside of the frame rod (FR) and mounted on the inside of the connecting member (CNT). At this time, at least one open line (OL) that is cut and opened can be provided at one end of the connecting member (CNT). A connecting member coupling groove (CCG) and a connecting member catching protrusion (CSJ) can be formed in a separation area (SA) separated by the open line (OL). The connecting member (CNT) can be positioned in the connecting member coupling groove (CCG), and the connecting member catching protrusion (CSJ) can be positioned to protrude from the connecting member (CNT). Therefore, the coupling force of the connecting member (CNT) and the frame rod (FR) according to the embodiment of the present invention can be increased.

[0191] Figure 35 is a drawing showing an assembled clothes drying rack according to an embodiment of the present invention.

[0192] Referring to FIG. 35, the assembly-type clothes drying rack (100) according to the embodiment of the present invention performs the connection between the first main frame rod (122-1) and the first support frame rod (142-1) and the corresponding connection members (CNT1 to CNT5) through a button-type connection member (BCM), so that the ease of assembly can be significantly improved, and the strength of the connection can be increased through the structure of the button-type connection member (BCM) and the corresponding connection members (CNT1 to CNT5) described above.

[0193] In addition, the assembly-type clothes drying rack (100) according to the embodiment of the present invention can solve corrosion problems and assembly difficulties by not forming any holes in the frame or the rod itself.

[0194] In addition, the assembly-type clothes drying rack (100) according to the embodiment of the present invention can be separated into individual frames in which the drying section (120) and the support section (140) that occupy the largest volume are separated, and in particular, the longest first support frame rod (142-1) is separated into upper and lower rods, and the volume can be significantly reduced by the structure of the mounting member (MTM), the fixing section (160), and the support section (180).

[0195] In addition, the assembly-type clothes drying rack (100) according to the embodiment of the present invention performs the connection of the first support frame rod (142-1), the fixing part (160), and the support part (180) through a single integrated connecting member having a simple structure and easy mounting, thereby reducing the volume, number, and type of parts while improving the ease of assembly.

[0196] Although representative embodiments of the present invention have been described in detail above, those skilled in the art will understand that various modifications can be made to the above-described embodiments without departing from the scope of the present invention.

[0197] For example, unlike the support (180) of FIG. 14 or FIG. 15, the support (180) may be provided in a shape as in FIG. 36. The support (180) of FIG. 36 may be formed by bending the portion that is to be mounted on the mounting hook (HK) into a “ㄷ” shape. Alternatively, unlike the assembly-type clothes drying rack (100) of FIG. 35 in which the respective parts of FIG. 1 are assembled, when the support (180) is provided in one stage, it may be assembled like the assembly-type clothes drying rack (100) of FIG. 37 or FIG. 38.
