Description

Assembled clothes hanger and connecting component thereof

Technical Field

The following disclosure relates to an assembled laundry rack and a connecting member thereof, which can remarkably reduce the volume or area of product package and maximize the convenience of assembly while being firmly and stably used.

Background

The floor-type laundry rack generally used has a structure in which a airing unit for airing laundry and a supporting unit for supporting the airing unit can be folded and unfolded, so that a producer can pack and sell the laundry in a folded state after production, and a user can store the laundry rack after folding when not in use.

However, in a first direction (e.g., length-wise) of the laundry stand, the area in the folded state is significantly smaller than in the unfolded state, but in other directions (e.g., width or height) the area in the folded state is not significantly different from the area in the unfolded state.

Thus, even the laundry rack in the folded state is still packaged and sold in a considerable volume or area. For the above reasons, when purchasing the laundry rack on line, it is difficult for consumers to directly or with a vehicle after purchasing, and when selling on line, it is difficult to distribute.

At this time, the X-axis, Y-axis, and Z-axis of fig. 1 can be regarded as one standard, and directions of respective components of other drawings are also described in the same standard as the coordinate axes of fig. 1 unless otherwise specified.

The terms first, second, etc. may be used to describe various components and the components are not limited by the terms. The term may be used to distinguish one component from another component. For example, a first element could be termed a second element, and, similarly, a second element could be termed a first element, without departing from the scope of the present invention.

In addition, the description of the shape or position of each component, etc. of the assembled laundry rack according to the embodiment of the present invention is based on the state in which each component is unfolded after being combined, unless otherwise stated.

Referring to fig. 1, the assembled laundry rack 100 according to the embodiment of the present invention includes a airing unit 120, a supporting unit 140, a fixing unit 160, a bearing unit 180, and first to sixth connection parts CNT1 to CNT6.

The airing unit 120 includes a pair of main frames 122 and a plurality of airing poles 124, the pair of main frames 122 being unfolded in a first direction (X-axis direction), the plurality of airing poles 124 being spaced apart from each other in a space where the pair of main frames 122 are spaced apart in a second direction (Y-axis direction). The pair of main frames 122 may collectively form a "V" or "one" shape when unfolded at an angle. The pair of main frames 122 may be coupled to each other by the first connection part CNT 1. The first connection part CNT1 may also be named as a main frame connection part.

The support unit 140 includes a pair of support frames 142 that are unfolded in the X-axis direction so as to support the airing unit 120 in a third direction (Z-axis direction). The pair of support frames 142 may collectively form a "V" shape that rotates 180 degrees when deployed at an angle. The pair of support frames 142 may be connected to each other by the second connection part CNT 2. The second connection part CNT2 may also be named as a support frame connection part. The first connection member CNT1 and the second connection member CNT2 may be collectively referred to as a frame connection member.

The second connection part CNT2 may be formed integrally with the first connection part CNT1 or may be formed separately from each of the first connection parts CNT 1.

The pair of support frames 142 may be connected to each other with the pair of main frames 122 through the third connection part CNT3.

The third connection part CNT3 may be formed integrally with at least one of the first connection part CNT1 and the second connection part CNT2, or may be formed separately from at least one of the first connection part CNT1 and the second connection part CNT 2.

The first to third connection parts CNT1 to CNT3 may be rotated within a certain angular range, independently or by another hinge part (not shown) with respect to a fixed axis thereof. Thereby, the pair of main frames 122 and the pair of support frames 142 connected to the first to third connection parts CNT1 to CNT3 may be rotated within respective angular ranges, whereby the airing unit 120 and the support unit 140 of the assembled laundry rack 100 according to the embodiment of the present invention may be folded or unfolded. The first to third connection parts CNT1 to CNT3 will be described in further detail later.

With continued reference to fig. 1, the pair of main frames 122 according to the embodiment of the present invention may include a pair of first main frame bars 122-1, a second main frame bar 122-2, and a pair of fourth connection parts CNT4, respectively. The pair of first main frame bars 122-1 included in one main frame 122 of the pair of main frames 122 may be referred to as a first pair of first main frame bars 122-1, and the pair of first main frame bars 122-1 included in the other main frame 122 may be referred to as a second pair of first main frame bars 122-1, thereby distinguishing. However, the first and second pairs of first main frame bars 122-1 and 122-1 are provided in the same structure, and thus the following description of the first main frame bars 122-1 may be applied to both the first and second pairs of first main frame bars 122-1 and 122-1.

The fourth connection part CNT4 may be named as a main frame bar connection part. The pair of first main frame bars 122-1 may be spaced apart in the Y-axis direction and arranged in parallel, and the second main frame bars 122-2 may be combined to be at right angles to the pair of first main frame bars 122-1 in a plane formed by the X-axis and the Y-axis. The pair of first main frame bars 122-1 and the second main frame bars 122-2 are coupled by a pair of fourth coupling parts CNT 4.

The pair of support frames 142 according to the embodiment of the present invention may include a pair of first support frame bars 142-1, a pair of second support frame bars 142-2, and a pair of fifth connection members CNT5, respectively. The pair of first support frame bars 142-1 included in one support frame 142 of the pair of support frames 142 may be referred to as a first pair of first support frame bars 142-1, and the pair of first support frame bars 142-1 included in the other support frame 142 may be referred to as a second pair of first support frame bars 142-1, thereby distinguishing them. However, the first and second pairs of first support frame bars 142-1 and 142-1 are provided in the same structure, and thus the following description of the first support frame bars 142-1 may be applied to both the first and second pairs of first support frame bars 142-1 and 142-1.

The fifth connection part CNT5 may be named as a support frame rod connection part. The fourth connecting member CNT4 and the fifth connecting member CNT5 may be collectively referred to as a frame bar connecting member.

The pair of first support frame bars 142-1 may be spaced apart in the Y-axis direction and arranged in parallel, and the second support frame bars 142-2 may be combined to be at right angles to the pair of first support frame bars 142-1 on a plane formed by the X-axis and the Y-axis. The pair of first and second support frame bars 142-1 and 142-2 are coupled by a pair of fifth coupling parts CNT 5.

At this time, the pair of first support frame bars 142-1 may be separated into the upper bars UR and the lower bars DR, respectively. The coupling and decoupling of the upper bars UR and the lower bars DR constituting the first supporting frame bars 142-1 will be described in further detail later.

Both ends of the first main frame bar 122-1 and the first support frame bar 142-1 according to an embodiment of the present invention are mounted with key-type coupling parts BCM.

Fig. 2 is a diagram illustrating that a key coupling part is mounted to a first main frame bar or a first support frame bar according to an embodiment of the present invention, fig. 3 is a diagram illustrating in further detail the key coupling part according to an embodiment of the present invention, and fig. 4 is a diagram illustrating coupling of a connection part corresponding to the key coupling part according to an embodiment of the present invention.

Referring to fig. 2 to 4, the key-type coupling parts BCM are installed at both ends of the first main frame bar 122-1 and the first support frame bar 142-1, respectively.

The key-type coupling member BCM mounted at one end of the first main frame bar 122-1 is key-type coupled with the first connection member CNT1 of fig. 1, and the key-type coupling member BCM mounted at the other end of the first main frame bar 122-1 is key-type coupled with the fourth connection member CNT4 of fig. 1.

As described above, the first support frame bar 142-1 is separated into the upper bar UR and the lower bar DR, and thus the key-type coupling parts BCM may be respectively installed at one end of the upper bar UR and the other end of the lower bar DR. The key-type coupling member BCM mounted at one end of the upper bar UR is key-type coupled with the second connection member CNT2 of fig. 1, and the key-type coupling member BCM mounted at the other end of the lower bar DR is key-type coupled with the fifth connection member CNT5 of fig. 1.

As described above, since both sides of the first main frame bar 122-1 and the first support frame bar 142-1 are coupled in a key type, convenience and firmness of the coupling can be greatly improved. The structure and manner of the key-press type coupling according to the embodiment of the present invention will be further described later.

The other end side of the upper shank UR may form a thread root, and one end side of the lower shank DR forms a thread crest corresponding to the thread root of the upper shank UR, so that the upper shank UR and the lower shank DR are coupled by threads. But is not limited thereto, the thread root may be formed at the inner side of the upper shank UR instead of the other end side thereof (i.e., the outer side of the upper shank UR does not form the thread root), or the upper shank UR and the lower shank DR may be coupled by another coupling member instead of being coupled by screw itself.

The key bonding part BCM includes an insertion unit IU inserted into the first main frame bar 122-1 or the first support frame bar 142-1, and a bonding unit CU formed by contacting one end thereof with the insertion unit IU and bonded with a corresponding connection part. The insertion unit IU and the combination unit CU may be formed as one body. At this time, the corresponding connection member CNT may be one of the first connection member CNT1, the second connection member CNT2, the fourth connection member CNT4, and the fifth connection member CNT5 of fig. 1, but fig. 4 shows an example in which the key bonding member is connected to the fourth connection member CNT4 or the fifth connection member CNT 5. An example in which the key-type coupling part BCM is connected to the first connection part CNT1 or the second connection part CNT2 will be described later.

The outer diameter of the insertion unit IU may be formed to be the same as the inner diameter of the first main frame bar 122-1 or the first support frame bar 142-1. The outer diameter of the combining unit CU may be formed to be the same as that of the first main frame bar 122-1 or the first support frame bar 142-1.

The coupling unit CU includes a coupling key CB and a first notch line CL1, the coupling key CB being formed to protrude from an outer circumferential surface of the coupling unit CU, the first notch line CL1 including a portion of an outer circumference of the coupling key CB and being formed by cutting the outer circumferential surface to prevent both ends thereof from being connected to each other. At this time, "the part periphery including the bonding key CB" may mean that it is formed by contact with the part periphery. But is not limited thereto, the first slit line CL1 may be cut into adjacent portions of the outer circumference according to the shape of the portions of the outer circumference thereof. The portion of the outer peripheral surface of the coupling unit CU, in which the coupling key CB is arranged and surrounded by the first notch line CL1, is referred to as an elastic sheet EP. The coupling unit CU may be implemented by a plastic or metal material having an arbitrary elastic coefficient, or the like.

When the coupling unit CU is inserted into its corresponding connection member, a force in the insertion direction is applied to the coupling key CB protruding from the outer circumferential surface of the coupling unit CU. At this time, the other end spaced apart from the insertion unit IU of the coupling unit CU is formed by being rounded in a direction in which the outer diameter thereof is reduced, so that it can be easily inserted into or separated from the inside of the corresponding connection member CNT.

The force applied to the bonding key CB is dispersed to the elastic sheet EP, and thus the elastic sheet EP may be depressed to the inner space. At this time, the connection of the elastic sheet EP to the outer circumferential surface of the coupling unit CU is maintained by the ends of the first slit line CL1 that are not connected to each other.

As the elastic sheet EP is sunk into the inner space of the coupling unit CU, the coupling key CB positioned at the elastic sheet EP and protruding therefrom may be inserted into the inner side of the connection member CNT. At this time, the corners of the coupling key CB are formed by rounding, so that the coupling unit CU can be more easily inserted into or separated from the inside of the connection member CNT corresponding thereto. When the coupling key CB is drawn out from the coupling hole CH after passing through the inner space of the corresponding connection member CNT by the pushing force, the elastic piece EP may be restored to its original position, i.e., to the same plane as the outer circumferential surface of the coupling unit CU.

Since the coupling key CB is drawn out from the coupling hole CH, the first main frame bar 122-1 or the first support frame bar 142-1 can be coupled with its corresponding connection part CNT by the key-type coupling part BCM. When separation from the corresponding connection member CNT is required, the coupling key CB is inserted into the corresponding connection member CNT by applying a force in a direction opposite to the insertion direction in a state where the coupling key CB is pressed, thereby achieving separation.

In the illustrated key bonding part BCM according to the embodiment of the present invention, the bonding key CB is formed in a rectangular shape with rounded corners, and the first incision line CL1 or the elastic sheet EP is formed in a nail shape, but is not limited thereto. The bonding key CB may be formed in a triangle, an inverted triangle, a pentagon, a hexagon, an ellipse, or a star shape, and the first incision line CL1 may be formed in a shape corresponding to the outer circumference of the bonding key CB included therein. At this time, the first notch line CL1 may be formed to include at least 1/2 or 2/3 or more of the outer circumference of the integrated key CB. As with the first notch line CL1, the elastic sheet EP may be formed to correspond to the shape of the combination key CB or to be independent of the shape of the combination key CB.

Preferably, the coupling unit CU of the key-type coupling unit BCM according to an embodiment of the present invention may further include one or a pair of second slit lines CL2. The second slit line CL2 is formed by cutting the outer circumferential surface from the other end of the coupling unit CU. When provided as a pair of second slit lines CL2, the pair of second slit lines CL2 may be configured to be symmetrical with respect to the combination key CB. The second slit line CL2 is coupled with the coupling wall CW of its corresponding connection member CNT, so that the coupling between the key coupling member BCM and its corresponding connection member CNT can be further secured.

As described above, both ends of the first main frame bar 122-1 and the first support frame bar 142-1 according to the embodiment of the present invention are mounted with the key-type coupling parts BCM, so that the assembly thereof becomes easy and firm. At this time, in order to facilitate and secure the coupling with the key coupling part BCM, the connection part according to the embodiment of the present invention is provided to correspond to the key coupling part BCM. Hereinafter, this will be described.

Referring to fig. 1, 4 and 5, the fourth connection part CNT4 may include a fourth body BD4 and a fourth coupling groove CG4. The fourth body BD4 may be formed such that one end of the inside thereof is opened and the other end is closed, and the key combination part BCM to which the first main frame bar 122-1 is mounted is inserted into and combined with the fourth body BD 4.

The fourth body BD4 has an outer peripheral surface openly formed with coupling holes CH corresponding to the coupling keys CB of the key-type coupling members BCM. As described above, the first main frame bar 122-1, i.e., the coupling key CH is drawn out from the coupling hole when the key coupling member BCM is coupled with the fourth connection member CNT 4.

The inner space of the fourth body BD4 may be formed in a shape corresponding to that of the first main frame lever 122-1 or the key-type coupling member BCM, for example, a cylindrical shape. Each frame or rod or the like according to the embodiment of the present invention is premised on being provided in the shape of a tube, and thus the member combined with each frame or rod is also provided in a shape corresponding to a cylinder unless otherwise specified. However, each frame or rod or the like according to the embodiment of the present invention may be provided in the shape of a quadrangular prism or the like, and in this case, a member combined with the frame or rod may be provided in the shape corresponding to the quadrangular prism or the like.

The inner diameter of the fourth body BD4 may be reduced stepwise at least once at the other end side thereof. Fig. 5 (b) shows an example in which the inner diameter of the fourth body BD4 decreases once from the first inner diameter id1 to the second inner diameter id 2. As the inner diameter of the fourth body BD4 is stepwise reduced, as shown in fig. 4, the coupling unit CU inserted into the key-type coupling member BCM of the fourth body BD4 can be more firmly provided.

The inner space of the fourth body BD4 may further include a combining wall CW protruding from the inner wall. As described above, the bonding wall CW is bonded to the second slit line CL2 of the key bonding part BCM.

The closed other end outer side of the fourth body BD4 may be formed in an arc shape to ensure convenience of use and safety.

The fourth coupling groove CG4 may protrude from the outside adjacent to the other end of the fourth body BD4, and it may be formed such that the inside is opened at one end and the other end is closed by the fourth body BD 4. But is not limited thereto. Since the fourth body BD4 is integrally formed with the fourth coupling groove CG4, the other end of the fourth coupling groove CG4 may not be closed and the inner space thereof may be connected with the inner space of the fourth body BD 4.

The second main frame bar 122-2 may be inserted and then mounted to the inner space where the key-type coupling part BCM is mounted. The inner space of the fourth coupling groove CG4 may be formed in a shape corresponding to that of the second main frame bar 122-2, for example, a cylindrical shape.

As described above, the assembled laundry rack according to the embodiment of the present invention optimizes the structures of the first and second main frame bars 122-1 and 122-2, the key-type coupling part BCM, and the fourth connection part CNT4, thereby enabling to achieve miniaturization of volume, weight, and parts while ensuring convenience of assembly and firmness after assembly.

But is not limited thereto. The second main frame bar 122-2 according to the embodiment of the present invention may also be installed at both ends thereof with key-type coupling parts BCM as in the first main frame bar 122-1. At this time, the fourth coupling groove CG4 may include the coupling hole CH or the coupling wall CW, as in the fourth body BD 4.

In addition, the fourth connection part CNT4 according to an embodiment of the present invention may have various structures capable of further firmly coupling the first main frame bar 122-1 with the second main frame bar 122-2 or the key type coupling part BCM. For example, a fourth reinforcing member RM4 may be provided at the connection portion of the fourth body BD4 and the fourth coupling groove CG4 to support or disperse the load caused by the coupling thereof.

The above description of the fourth connection part CNT4 may be equally applicable to the fifth connection part CNT5, and the description of the combination of the fourth connection part CNT4 and the first and second main frame bars 122-1 and 122-2 or the key combination part BCM may be equally applicable to the combination of the fifth connection part CNT5 and the first and second support frame bars 142-1 and 142-2 or the key combination part BCM.

Fig. 6 is a view showing the first to third connection parts according to an embodiment of the present invention, and fig. 7 is a view for describing the combination of the first to third connection parts with the key-type coupling part.

Referring to fig. 1, 6 and 7, the first connection part 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. The center of each first combining plate CP1 may form a first through hole TH1, and each first body BD1 may be formed to be connected with the corresponding first combining plate CP 1. The key-type coupling member BCM mounted at one end of the first main frame bar 122-1 is inserted into and coupled with the open end of the first body BD1. Accordingly, the inner space of each first body BD1 can be formed in a shape corresponding to the shape of the coupling unit CU of the key-type coupling member BCM, for example, a cylindrical shape.

The second connection member CNT2 may be provided in the same shape as the first connection member CNT 1. That is, the second connection member CNT2 may include a pair of second coupling plates CP2 and a pair of second bodies BD2, respectively, the second coupling plates CP2 having a second through hole TH2 formed at the center thereof, and the second bodies BD2 being connected to the second coupling plates CP2 and forming a cylindrical inner space. The diameters of the first through holes TH1 and the second through holes TH2 may be the same. The key-type coupling member BCM mounted to one end of the first support frame bar 142-1 is inserted into and coupled with the open end of the second body BD 2.

The coupling of the first body BD1 of the first connection member CNT1 with the key coupling member BCM mounted at one end of the first main frame bar 122-1 is the same as the above-described technical idea of the coupling of the fourth body BD4 of the fourth connection member CNT4 with the key coupling member BCM mounted at the other end of the first main frame bar 122-1, and the technical idea of the coupling of the second body BD2 of the second connection member CNT2 with the key coupling member BCM mounted at the other end of the first support frame bar 122-1.

That is, the coupling hole CH of the coupling key CB corresponding to the key coupling member BCM is openly formed by the outer circumferential surface of the first body BD1, and the coupling key CB is drawn out from the coupling hole CH when the key coupling member BCM mounted at one end of the first main frame lever 142-1 is coupled to the first body BD 1. In addition, the inner diameter of the first body BD1 is reduced stepwise at least once at the other end side thereof, so that the coupling unit CU of the key-type coupling member BCM is more firmly provided. In addition, the inner space of the first body BD1 may further include a coupling wall CW protruding from the inner wall so as to be coupled with the second slit line CL2 of the key coupling member BCM.

However, unlike the fourth body BD4, the shape of the other end of the first body BD1 may be formed in a shape suitable for connection with the first coupling plate CP 1. The second body BD2 can be formed in the same shape as the first body BD 1.

The first connection part CNT1 and the second connection part CNT2 may be coupled by the third connection part CNT 3.

The first through holes TH1 and the second through holes TH2 are positioned at the same position by overlapping the pair of first coupling plates CP1 of the first coupling member CNT1 and the pair of second coupling plates CP2 of the second coupling member CNT2 with each other, the center rod CR may be installed at one side of the overlapped first through holes TH1 and second through holes TH2 and provided from side to side, and the third coupling member CNT3 may be installed at the other side.

The third connection part CNT3 may include a connection hook CK and a set screw FS. First, the connection hook CK may be inserted into the first through hole TH1, the second through hole TH2, and the inside of the center rod CR in the overlapping region of the center rod CR, and then the fixing screw FS may be inserted into the connection hook CK and mounted.

With the above structure, the first and second connection members CNT1 and CNT2 can be rotated, and thus the airing unit 120 and the supporting unit 140 can be used to be foldable. Further, since the side surface of the connecting hook CK is partially cut and the protruding groove is formed therein, when the fixing screw FS is attached to the connecting hook CK, the center rod CR can be further bonded to the first through hole TH1 and the second through hole TH2 by applying pressure, and the first connecting member CNT1 to the third connecting member CNT3 can be firmly bonded.

In this case, in order to further secure the coupling, a third fixing ring FR3 may be further coupled between the first through hole TH1, the second through hole TH2, and the center rod CR, which are overlapped. In addition, when the rotation angles of the first and second connection members CNT1 and CNT2 are limited, the supporting unit 140 of the assembled laundry rack 100 according to the embodiment of the present invention may be fixed without exceeding a certain angle even without including the additional fixing unit 160.

Referring back to fig. 1, the fixing unit 160 fixes the support unit 140 to move by connecting the pair of support frames 142 of the support unit 140.

Referring to fig. 1 and 8, a fixing unit 160 according to an embodiment of the present invention may include a pair of fixing frames 162 and a pair of fixing bars 164.

Both ends of the inner side of each of the fixing frames 162 may form an open frame penetration hole FTH. In addition, the middle portion of each of the fixing frames 162 is foldably formed so that it can be folded together when the assembled laundry rack 100 according to the embodiment of the present invention is folded in the assembled state.

A pair of fixing rods 164 may be installed to penetrate through the frame penetration holes FTH, respectively. In the assembled state of the assembled laundry rack 100 according to the embodiment of the present invention, each of the fixing bars 164 may be provided to correspond to a spaced distance sd between a pair of the first support frame bars 142-1 provided to be spaced apart in the Y-axis direction.

The fixing unit 160 according to an embodiment of the present invention assists the airing unit 120 to perform its function in addition to fixing the spaced distance of the pair of support frames 142. To this end, the fixing unit 160 according to an embodiment of the present invention may further include a plurality of auxiliary laundry rod coupling grooves 166 and a plurality of auxiliary laundry rods 168. The auxiliary laundry pole coupling groove 166 may be formed at the inner side of the fixing frame 162. At this time, the auxiliary laundry rod 168 is provided at a length corresponding to the spaced distance of the pair of fixing frames 162 in the Y-axis direction, and thus may be shorter than the fixing rod 164.

Referring back to fig. 1, the supporting unit 180 is coupled to a pair of support frames 142 and any one of the plurality of laundry poles 124, which are provided and correspond to each other. The angle formed by the airing unit 120 and the plane formed by the X-axis and the Y-axis may be different according to the position of the airing rod 124 to which the supporting unit 180 is coupled.

Referring to fig. 1 and 9, the bearing unit 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 be provided in a "+" shape, respectively. Both edges of the upper frame 182 may be folded to place the cloth rail 124. The upper frame 182 and the lower frame 184 can be foldably connected. For example, the upper frame 182 may be bent at both ends to form a ring, and the lower frame 184 may be inserted into the ring to be coupled thereto. Both ends of the lower frame 184 may be provided with bending.

At this time, the width WD of the lower frame 184 in the X-axis direction is longer than the spacing distance sd of the first support frame bar 142-1 in the Y-axis direction. Accordingly, the lower frame 184 is supported by the pair of first support frame bars 142-1, and the upper frame 182 connected to the lower frame 184 can support the corresponding laundry poles 124 by the above-mentioned supporting force.

Thanks to the above-described structure of the supporting unit 180, it is possible to minimize the volume and weight of the assembled laundry rack 100 before assembly and to secure convenience of use through the firmness after assembly.

In the above, in the assembled laundry rack 100 according to the embodiment of the present invention, the technical idea of the present invention is mainly described around the key-type coupling part BCM. Further, in the assembled laundry rack 100 according to the embodiment of the present invention, the structures of the airing unit 120 and the supporting unit 140, etc., and the combination thereof can minimize the packing volume and weight before assembly and improve the convenience of assembly and the firmness of the assembled state. Hereinafter, this will be described.

Referring to fig. 10, the airing unit 120 according to an embodiment of the present invention is formed in a structure capable of airing laundry. At this time, in order to prevent holes from being formed on the main frame 122 according to the embodiment of the present invention, the airing unit 120 of the present invention may be located between the main frames 122 spaced apart by the plurality of airing bars 124 through the additional bracket means MTM.

The plurality of laundry poles 124 are mounted on the bracket part MTM and placed on the first main frame pole 122-1. Fig. 10 shows an example in which the bracket member MTM is provided in two, but is not limited thereto. The bracket member MTM may be provided in one or three or more according to the size of the airing unit 120 and the like. In addition, the same or different numbers of clothes poles 124 may be placed on each of the bracket members MTM. For example, as shown in fig. 10, three clothes poles 124 may be mounted to each of the two bracket members MTM. Alternatively, unlike fig. 10, three clothes poles 124 may be mounted on one bracket part MTM, and four clothes poles 124 may be mounted on the other bracket part MTM. Further, one of the carrier members MTM may have one of the clothes poles 124 mounted thereon, respectively.

When each assembly of the assembled laundry rack 100 according to the embodiment of the present invention is disassembled and then packaged, the number of the bracket parts MTM, the length md of the bracket parts MTM, or the number of the laundry poles 124 combined therewith may be variously set according to a required packaging area. For example, the sum of the lengths md of each of the bracket parts MTM may correspond to the length of one of the first main frame bars 122-1. For example, for sales or custody of the assembled laundry rack 100 according to an embodiment of the present invention, if the ratio of the lateral length to the longitudinal length of the required packing case is 2:5, the width of at least one of the bracket parts MTM may be equipped to be less than or equal to 2/5 of the length of one of the first main frame bars 122-1.

Referring to fig. 10 and 11, fig. 10 shows the bracket member MTM in the mounting direction, and fig. 11 shows the bracket member MTM inverted.

The bracket part MTM may include a pair of bracket frames MF and a plurality of laundry rack coupling grooves DG.

A pair of bracket frames MF are combined with the corresponding first main frame bars 122-1, respectively. To improve the easiness and safety of the above-mentioned coupling, a pair of bracket frames MF may be formed in a semi-cylindrical shape to partially surround and be coupled with the first main frame bars 122-1, respectively. For example, the perimeter of the first region of the carriage frame MF may be provided to be greater than 1/2 of the perimeter of the first main frame bar 122-1. As described above, the bracket frame MF is easily disassembled and assembled on the first main frame bar 122-1 while improving the coupling firmness, and the costs required for weight and production, etc. of the bracket frame MF can be reduced by setting the circumference of the second region of the bracket frame MF to be less than 1/2 of the circumference of the first main frame bar 122-1.

At this time, the second region of the carrier frame MF may be a region between the laundry rack coupling grooves DG, and may be formed in the shape of an arc as shown in the drawing. The first region may be a region other than the second region. The bracket frame MF may be formed by injection molding. The bracket frame MF according to the embodiment of the present invention may be subjected to a process (a) of punching or the like to further reduce the weight.

The plurality of laundry pole coupling grooves DG may be formed to protrude outside the bracket frame MF. The plurality of laundry rack coupling grooves DG may be formed at regular intervals in the X-axis direction on the side surface of the bracket frame MF.

One end of the airing rod 124 may be inserted into the first airing rod coupling groove DG1 of the airing rod coupling grooves DG or separated from the first airing rod coupling groove DG 1. The other end of the cloth rail 124 may be inserted into the second cloth rail coupling groove DG2 of the cloth rail coupling grooves DG, or separated from the second cloth rail coupling groove DG 2.

At this time, the first and second laundry bar coupling grooves DG1 and DG2 are provided in a cylindrical shape opened in the Y-axis direction, and at this time, a part of the cylindrical side surface may be formed in a cut-out shape. For example, the first and second laundry bar coupling grooves DG1 and DG2 are formed in a shape in which a portion of a cylindrical side surface is cut in a rectangular shape, and thus the first height h1 is provided to be shorter than the second height h2.

Therefore, according to the embodiment of the present invention, the laundry lever 124 can be easily coupled to the laundry lever coupling groove DG. That is, due to the cut-out shape, after one end of each of the airing bars 124 is inserted into the first airing bar coupling groove DG1, the other end thereof can be inserted into the second airing bar coupling groove DG2 by tilting the airing bars 124, thereby benefiting from the originally installed airing bars 124, and solving the problem of barely folding up the airing bars 124 when installing other airing bars 124. The same applies to the separation. Even so, the coupling capability of the cloth rail 124 and the cloth rail coupling groove DG is not affected, and therefore, the cloth rail 124 can be prevented from being separated from the cloth rail coupling groove DG regardless of the force applied from any direction.

Preferably, the cut shapes of the first and second cloth rail coupling grooves DG1 and DG2 are formed below (in the negative direction of the Z axis) in the assembled state, so that laundry dried on the cloth rail 124 can be prevented from being caught in the cut shapes.

As described above, the airing unit 120 according to the embodiment of the present invention can solve the problem of corrosion or difficulty in assembly because no holes are formed, and can be stronger when used after assembly while improving convenience of packaging and handling by significantly reducing its volume and weight.

As described above, the first and second laundry lever coupling grooves DG1 and DG2 are formed in the same shape, and since the bracket members MTM are provided in the same shape regardless of the installation position, it is possible to more effectively control the production cost, inventory management, and the like. But is not limited thereto. Of the first and second cloth rail coupling grooves DG1 and DG2, only one coupling groove may have a partially cut shape.

Further, the first and second laundry bar coupling grooves DG1 and DG2 may be formed in different shapes. For example, the first laundry lever coupling groove DG1 may be formed to be opened in the positive direction of the X-axis, and the second laundry lever coupling groove DG2 may be formed to be opened in the negative direction of the X-axis. At this time, if the pair of bracket frames MF are placed opposite to each other by being respectively placed on the corresponding first main frame bar 122-1, the opening directions of the first and second laundry bar coupling grooves DG1 and DG2 are symmetrical with respect to the Y-axis. For example, the first cloth rail coupling groove DG1 may be opened in the positive direction of the X-axis, and the second cloth rail coupling groove DG2 may be opened in the negative direction of the X-axis.

By forming at least one laundry lever coupling reinforcing member DRM outside the laundry lever coupling groove DG, it is possible to support (disperse) the load caused by coupling with the laundry lever 124.

Hereinafter, an integral connection part according to an embodiment of the present invention, which can minimize the number and kind of parts and make bonding easy and firm without punching holes in a frame or a bar or the like, will be described.

Fig. 12 is a diagram showing integral connection parts according to an embodiment of the present invention, and fig. 13 is an exploded view showing a structure connected by the integral connection parts according to an embodiment of the present invention.

Referring to fig. 12 and 13, the integral connection part may be referred to as a sixth connection part CNT6. The sixth connection member CNT6 may include a sixth body BD6, a fixing unit coupling groove FXG, and a pair of bearing unit coupling tabs SW.

As described above, the first support frame bar 142-1 according to the embodiment of the present invention is separated into the upper bar UR and the lower bar DR, and the position of the sixth body BD6 of the sixth connection member CNT6 may be fixed by the sixth connection member CNT6 after penetrating the upper bar UR in a state where the upper bar UR and the lower bar DR are coupled and the sixth fixing ring FR6 is mounted to the coupling portion thereof. The sixth body BD6 of the sixth connection member CNT6 has an inner diameter slightly larger than or the same as the outer diameter of the upper rod UR and smaller than the outer diameter of the sixth fixing ring FR 6.

The fixing lever 164 of the fixing unit 160 may be inserted and then mounted to the fixing unit coupling groove FXG. The fixing unit coupling groove FXG protrudes from the outer side of the sixth connecting member CNT6 and may be formed in a cylindrical shape with one end opened and the other end closed by the sixth body BD 6. However, the other end of the fixing unit coupling groove FXG can be formed by being coupled to the sixth body BD 6.

A corresponding one of the two ends of the lower frame 184 of the supporting unit 180 may be penetrated and then mounted to each of the pair of supporting unit coupling wings SW. The pair of the supporting unit coupling tabs SW may include sixth through holes TH6, respectively, which are formed to protrude from the outside of the sixth connection member CNT6 and penetrate the supporting unit coupling tabs SW. The pair of the supporting unit coupling wings SW may be provided to be symmetrical to each other with respect to the fixing unit coupling groove FXG.

Since the holding unit coupling tabs SW are provided as a pair symmetrical to each other with respect to the fixing unit coupling groove FXG, even though the installation positions of the sixth connection members CNT6 are different, that is, any one of the 4 first support frame bars 142-1 can be used.

A sixth reinforcing member RM6 may be further provided at the connection portion of the sixth body BD6 and the fixing unit coupling groove FXG or at the connection portion of the sixth body BD6 and the bearing unit coupling tab SW to support or disperse the load caused by the coupling thereof.

Referring to fig. 14, the first support frame bar 142-1, the fixing unit 160, and the bearing unit 180 may be all combined by one integral connection member (i.e., the sixth connection member CNT 6) and inserted into the first pair of first support frame bars 142-1 combined with the fixing ring FR6 when the sixth connection member CNT6 is installed, so that miniaturization of parts and convenience of assembly may be improved.

Referring to fig. 13 and 15, unlike fig. 13, the supporting unit coupling tabs SW of the sixth coupling member CNT6 of fig. 15 may be provided with one. When the supporting unit coupling tab SW is provided in one, the supporting unit coupling tab SW may be formed at the left or right side of the fixing unit coupling groove FXG according to the position where the sixth connection member CNT6 is mounted, i.e., according to which of the first support frame bars 142-1 the sixth connection member CNT6 is mounted.

Referring to fig. 16, the assembled laundry rack 100 according to the embodiment of the present invention implements the coupling of the first main frame bar 122-1 and the first support frame bar 142-1 with the corresponding connection parts (CNT 1 to CNT 5) through the key-type coupling parts BCM, and thus can significantly improve the convenience of assembly, and enhance the coupling firmness through the structure of the key-type coupling parts BCM with the corresponding connection parts (CNT 1 to CNT 5) as described above.

In addition, the assembled laundry rack 100 according to the embodiment of the present invention does not form holes in the frame or the rod itself, and thus can solve the problems of corrosion and difficulty in assembly.

In addition, the airing unit 120 and the supporting unit 140 occupying the largest volume in the assembled type airing hanger 100 according to the embodiment of the present invention can be separated into each frame, particularly, the longest first supporting frame pole 142-1 into upper and lower poles, and the volume thereof can be remarkably reduced by means of the structure of the bracket component MTM, the fixing unit 160 and the supporting unit 180.

In addition, the assembled laundry rack 100 according to the embodiment of the present invention implements the combination of the first support frame bar 142-1, the fixing unit 160, and the bearing unit 180 through the single integrated connection member CNT having a simple structure and convenient installation, thereby reducing the volume, number, and variety of components while improving the convenience of assembly.

While representative embodiments of the present invention have been described in detail above, those skilled in the art to which the present invention pertains will appreciate that various changes can be made to the above-described embodiments without departing from the scope of the invention.
