Description

Technical Field

[0001] The present disclosure relates to the field of object hanging racks, and in particular, to a wall-mounted object hanging rack. Background Art

[0002] As people's demand for space utilization increases, traditional floor-mounted storage tools can no longer meet the requirements for efficient use of space in living environments. Wall-mounted racks, as a storage tool, can store clothes and other items on the wall, which not only saves floor space, but also improves the cleanliness and aesthetics of the room.

[0003] However, after installation, most wall-mounted racks have a fixed storage pattern and cannot be flexibly adjusted according to user needs, which limits the applicability of the storage space, for example, the storage space in the width direction, thereby affecting the overall storage effect and user experience. Summary of the invention

[0004] In view of this, the present disclosure provides a wall-mounted hanging rack, aiming to solve the problem that the storage space in the width direction cannot be flexibly adjusted.

[0005] The wall-mounted object rack includes N columns, N support plates, N-1 layers and N fixings. Each column is configured to be fixed to the wall extending in the up-down direction, and the N columns are arranged spaced apart from each other in the width direction, and N is greater than or equal to 3. The N support plates are respectively arranged on the N columns, and each support plate is located on the side of the corresponding column away from the wall in the depth direction. Each layer is supported by two adjacent support plates, and the two adjacent layers have an overlapping portion in the width direction. The two adjacent layers move relative to each other in the width direction to change the size of the overlapping portion in the width direction, and each layer includes a cross bar extending in the width direction. The N fixings are respectively arranged on the N support plates, and each fixing can be operated to move between a release position and a locking position relative to the corresponding support plate. When the fixing is in the release position, the fixing is spaced apart from the cross bar of the corresponding layer; when the fixing is in the locking position, the fixing is locked with the cross bar to fix the layer to the support plate.

[0006] According to the above implementation, the operator can change the size of the overlapping part in the width direction by adjusting the distribution of two adjacent layers in the width direction, thereby changing the width of the storage space to meet different storage needs. In addition, by operating the fixing member to move between the release position and the engagement position, the operator can easily adjust the position of the crossbar on the support plate and fix it without additional tools, thereby improving the operating efficiency of adjusting the storage space.

[0007] In one possible implementation, a mounting recess is provided on the top of the support plate, the cross bar is received by the mounting recess, the fixing member is provided with a downwardly open receiving slot, the receiving slot receives the top of the support plate, and the fixing member has a snap-fit ​​recess open to one side in the depth direction; when the fixing member is in the snap-fit ​​position, the snap-fit ​​recess receives the cross bar.

[0008] By operating the fixing member to move between the release position and the engagement position relative to the support plate, the operator can conveniently adjust the position of the cross bar on the support plate and fix it.

[0009] In a possible implementation, when the fixing member is located at the engaging position and the cross bar is not disposed in the installation recess, the distance between the top of the engaging recess and the bottom of the installation recess is smaller than the diameter of the cross bar.

[0010] When the cross bar is installed in place, it will be squeezed by the fixing member and the support plate, thereby forming an interference fit, so that the cross bar can be stably received in the engaging recess, reducing the possibility of loosening or sliding during use, thereby enhancing the stability of the structure.

[0011] In a possible implementation, a locking notch is provided at the top of the support plate, the locking notch is located on a side of the mounting notch away from the corresponding column, the locking notch is provided with a first edge and a second edge in sequence in a direction away from the column, the first edge is provided with a first extension extending toward the second edge, the first extension is provided with a first locking protrusion protruding downward; the fixing member is provided with a locking portion, the locking portion includes a second extension extending toward the column, the second extension is provided with a second locking protrusion protruding upward. The locking notch receives the locking portion, and as the fixing member moves from the release position to the engagement position, the locking portion moves from the unlocking position to the locking position in the locking notch; when the locking portion is in the locking position, the second locking protrusion is located on a side of the first locking protrusion closer to the column, so that the second locking protrusion abuts against the first locking protrusion.

[0012] By judging whether the locking recess receives the locking portion, the operator can determine whether the fixing member reaches the engaging position, thereby judging whether the fixing member is installed in place.

[0013] In a possible implementation, the fixing member is provided with an open slot which is open upward, the open slot is connected with the receiving slot, and the locking portion is located in the open slot.

[0014] Since the locking part is located in the open groove, it is convenient for the operator to observe the matching of the second locking protrusion and the first locking protrusion, thereby judging whether the fixing member has reached the engaging position. In addition, since the open groove is connected with the receiving slot, the second locking protrusion is not blocked in the up and down directions, which is convenient for opening the mold during the injection molding process.

[0015] In one possible implementation, the fixing member includes two side walls forming a receiving slot, and the open slot is formed with a first slot surface and a second slot surface on each side wall, the first slot surface is closer to the column than the second slot surface, the second extension portion includes a cross bar portion and a pair of arm portions, the pair of arm portions are respectively arranged on the two second slot surfaces and extend toward the column, the ends of the pair of arm portions facing away from the second slot surfaces are connected to the cross bar portion, and the second locking protrusion protrudes upward from the cross bar portion.

[0016] According to the above structure, the crossbar, the pair of arms and the two side walls can enclose a part of the space in the fixing part, so that the locking part is hollowed out, which makes it easy to deform the locking part and abut the second locking protrusion against the first locking protrusion. In this way, the operator can lock the fixing part to the support plate with less effort, thereby ensuring a good installation experience. On the other hand, since the locking part is hollowed out, it is easier to open the mold when manufacturing the fixing part by injection molding, thereby reducing the manufacturing difficulty.

[0017] In one possible implementation, the support plate is provided with a fixing groove extending in the depth direction, the fixing member includes two side walls forming a receiving slot, each of the two side walls has a fixing block extending toward the other side wall, the two fixing blocks are spaced apart in the depth direction, and the two fixing blocks extend into the fixing groove.

[0018] The cooperation between the fixing groove and the fixing block can limit the displacement of the fixing member in the up-down direction, so that it is stably placed on the support plate, thereby ensuring the stability of the structure. On the other hand, the two fixing blocks of the limiting fixing member are arranged at intervals, and at the same time, they are each spaced apart from the engaging notches of the limiting cross bar. Such position distribution makes the stress distribution inside the fixing member more dispersed, which is beneficial to the stability of the structure.

[0019] In a possible implementation, the support plate is provided with a fixing groove extending in the depth direction, the fixing member includes two side walls forming a receiving slot, one of the two side walls is provided with a fixing block extending toward the other side wall, and the fixing block extends into the fixing groove.

[0020] The cooperation between the fixing groove and the fixing block can limit the displacement of the fixing member in the up and down directions, so that the fixing member is stably placed on the support plate, thereby ensuring the stability of the structure.

[0021] In a possible implementation, the support plate is provided with a locking groove extending in the depth direction, one of the two side walls is provided with a locking block extending toward the other side wall, and the locking block extends into the locking groove. As the fixing member moves from the release position to the engagement position, the locking block slides from the unlocking position to the locking position in the locking groove; when the locking block is in the locking position, the sliding of the locking block toward the unlocking position is locked.

[0022] By judging whether the locking block slides to the locking position, the operator can determine whether the fixing member reaches the engaging position, thereby judging whether the fixing member is installed in place.

[0023] In one possible implementation, the locking groove has a locking groove section, which limits the locking block from sliding from the locking position to the unlocking position; the locking groove section has a first side wall and a second side wall relative to each other, the first side wall protrudes toward the second side wall, and the second side wall is recessed in a direction away from the first side wall.

[0024] When the locking block passes through the locking groove section, the operator can know that the locking block has reached the locking position through the sound of the two engaging, and thus stop moving the fixing piece.

[0025] In a possible implementation, the thickness of the locking block gradually decreases in a direction away from the side wall where the locking block is located.

[0026] In the process of the locking block sliding from the unlocking position to the locking position, the portion of the locking block with a smaller thickness can pass through the locking groove section first, so that the sliding can be completed smoothly. In the process of the locking block sliding from the locking position to the unlocking position, the portion of the locking block with a larger thickness cannot pass through the locking groove section, so the sliding is locked.

[0045] The following is an exemplary description of the embodiments of the present disclosure in conjunction with the accompanying drawings. It should be understood that the present disclosure can be implemented in a variety of ways and should not be construed as being limited to the embodiments described here. The embodiments described here are only for a more thorough and clear understanding of the present disclosure.

[0046] The present disclosure provides a wall-mounted object rack 100. The wall-mounted object rack 100 is a storage tool that can store items such as clothes on the wall. Figure 1The wall-mounted object rack 100 structure includes three columns 10, three support plates 20 and two layer plates 30. The three columns 10 are fixed to the wall in an extending manner in the up-down direction, and the three columns 10 are arranged at intervals from each other in the width direction. The three support plates 20 are respectively arranged on the three columns 10, and each support plate 20 is located on the side of the corresponding column 10 away from the wall in the depth direction. Each layer plate 30 is supported by two adjacent support plates 20. However, after the installation is completed, the storage pattern of the wall-mounted object rack 100 is fixed and cannot be flexibly adjusted according to the needs of the user.

[0047] In view of this, an embodiment of the present disclosure provides a wall-mounted object rack 100. Figure 1 and Figure 2 In the wall-mounted object rack 100, two adjacent layers 30 have an overlapping portion in the width direction, and the two adjacent layers 30 move relative to each other in the width direction to change the size of the overlapping portion in the width direction. Each layer 30 includes a cross bar 31 extending along the width direction.

[0048] Continue to refer Figure 1 The wall-mounted rack 100 further includes three fixing members 40, which are respectively disposed on three support plates 20, and each fixing member 40 can be operated to move between a release position and a locking position relative to the corresponding support plate 20. Figure 3A and Figure 3B When the fixing member 40 is located at the release position, the fixing member 40 is spaced from the cross bar 31 of the corresponding layer plate 30. When the fixing member 40 is located at the engagement position, the fixing member 40 is engaged with the cross bar 31 to fix the layer plate 30 to the support plate 20.

[0049] According to the above implementation, the operator can change the size of the overlapping part in the width direction by adjusting the distribution of two adjacent layer plates 30 in the width direction, thereby changing the width of the storage space to meet different storage needs. In addition, by operating the fixing member 40 to move between the release position and the engagement position, the operator can conveniently adjust the position of the cross bar 31 on the support plate 20 and fix it without additional tools, thereby improving the operating efficiency.

[0050] It is understood that the number of columns 10, support plates 20, layer plates 30 and fixing members 40 is only exemplary, and the present disclosure does not impose any particular limitation thereto. As long as the number of columns 10, support plates 20 and fixing members 40 is N, and the number of layer plates 30 is (N-1), N can be greater than 3.

[0051] It is understood that in the present disclosure, directional descriptions such as "up", "down", "left", "right", "front", "back", etc. are relative rather than absolute. These directional descriptions are applicable when the elements in the present disclosure are in the placement postures and placement positions shown in the figures. It should be noted that in the drawings of the present disclosure, arrows Z+ and Z- can be used to indicate the two sides of the up and down directions respectively; arrows Y+ and Y- can be used to indicate the two sides of the width direction respectively, i.e. the left and right sides of the left-right direction; arrows X+ and X- can be used to indicate the two sides of the depth direction respectively, i.e. the front and back sides of the front-back direction. The up and down directions, the width direction, and the depth direction are perpendicular to each other.

[0052] refer to Figure 1 and Figure 2 The top of the support plate 20 may be provided with a mounting recess 21, and the cross bar 31 is received by the mounting recess 21. Figure 5 The fixing member 40 is provided with a receiving slot 41 which is open downwards, and the receiving slot 41 receives the top of the support plate 20, and the fixing member 40 has a snap-fitting notch 42 which is open to one side in the depth direction. When the fixing member 40 is in the snap-fitting position, the snap-fitting notch 42 receives the cross bar 31. By operating the fixing member 40 to move between the release position and the snap-fitting position relative to the support plate 20, the operator can conveniently adjust the position of the cross bar 31 on the support plate 20 and fix it.

[0053] As an example, the fixing member 40 can be installed at a position close to the column 10 to ensure the aesthetics of the overall structure. In addition, the position close to the column 10 is not easily touched during normal use, thereby reducing the probability of being damaged during use.

[0054] It should be noted that Figure 2 The support plate 20 is shown as being located at the leftmost side in the width direction, so in this support plate 20, only one cross bar 31 is placed in the mounting recess 21. For the support plate 20 located in the middle position, two cross bars 31 belonging to different layer plates 30 are placed in the mounting recess 21, and both cross bars 31 can be received by the engaging recess 42 of the fixing member 40.

[0055] refer to Figure 3C When the fixing member 40 is in the engaging position and the cross bar 31 is not disposed in the installation recess 21, the distance H between the top of the engaging recess 42 and the bottom of the installation recess 21 is smaller than the diameter D of the cross bar 31. In this way, when the cross bar 31 is installed in place, it will be squeezed by the fixing member 40 and the support plate 20 to form an interference fit, thereby ensuring that the cross bar 31 is firmly fixed in the engaging recess 42, reducing the possibility of it being loose or sliding during use, thereby enhancing the stability of the structure.

[0056] refer to Figures 4 to 6The support plate 20 may be provided with a fixing groove 23 extending in the depth direction, and the fixing member 40 may include two side walls 43 forming a receiving slot 41, one of the two side walls 43 is provided with a fixing block 431 extending toward the other side wall, and the fixing block 431 extends into the fixing groove 23. The cooperation between the fixing groove 23 and the fixing block 431 can limit the displacement of the fixing member 40 in the up-down direction, so that it is stably placed on the support plate 20, thereby ensuring the stability of the structure.

[0057] Continue to refer Figures 4 to 6 The support plate 20 may be provided with a locking groove 24 extending in the depth direction, and one of the two side walls 43 is provided with a locking block 432 extending toward the other side wall 43, and the locking block 432 extends into the locking groove 24. As the fixing member 40 moves from the release position to the engagement position, the locking block 432 slides from the unlocking position to the locking position in the locking groove 24. When the locking block 432 is located at the locking position, the sliding movement of the locking block 432 toward the unlocking position is locked. By judging whether the locking block 432 slides to the locking position, the operator can determine whether the fixing member 40 has reached the engagement position, thereby judging whether the fixing member 40 is installed in place.

[0058] Continue to refer Figure 4 The locking groove has a locking groove section 241, and the locking groove section 241 limits the locking block 432 from sliding from the locking position to the unlocking position. The locking groove section 241 has a first side wall 2411 and a second side wall 2412 opposite to each other, the first side wall 2411 protrudes toward the second side wall 2412, and the second side wall 2412 is recessed in a direction away from the first side wall 2411. When the locking block 432 passes through the locking groove section 241, the operator can know that the locking block 432 has reached the locking position by the sound of the two engaging, thereby stopping the movement of the fixing member 40.

[0059] refer to Figure 4 and Figure 6 , the thickness of the locking block 432 gradually decreases in the direction away from the side wall 23 where it is located. In this way, when the locking block 432 slides from the unlocking position to the locking position, the portion with a smaller thickness in the locking block 432 can first pass through the locking groove section 241, so that the sliding can be completed smoothly, and when the locking block 432 slides from the locking position to the unlocking position, the portion with a larger thickness in the locking block 432 cannot pass through the locking groove section 241, so the sliding is restricted.

[0060] refer to Figure 6Each side wall 43 may be provided with a guide portion 46 extending toward the other, and the two side surfaces of the support plate 20 are respectively against the two guide portions 46. The two guide portions 46 can provide good guidance for the support plate 20, ensuring that it can move along the depth direction during installation and avoid its deviation in the width direction, thereby improving the installation efficiency of the fixing member 40. As an example, the guide portion 46 may extend along the depth direction.

[0061] Continue to refer Figure 6 The top of the receiving slot 41 may have a guide protrusion 461 extending downward, and when the receiving slot 41 receives the support plate 20, the top of the support plate 20 contacts the guide protrusion 461. In this way, during the movement, the contact area between the support plate 20 and the fixing member 40 can be reduced, thereby reducing the resistance encountered by the fixing member 40 during the movement.

[0062] Continue to refer Figure 6 , a side wall 43 of the fixing member 40 extends downward and bends in a direction away from the fixing member 40 to form a hand-held portion 47 for the operator to hold, so as to facilitate the fixing member 40 to be withdrawn from the engaged position. As an example, the hand-held portion 47 and the locking block 432 can be located on the same side wall 43. When the hand-held portion 47 is pulled, the locking block 432 also leaves the locking groove 24, so as to facilitate the fixing member 40 to be withdrawn from the engaged position.

[0063] refer to Figure 7 and Figure 8 The supporting plate 20 and the column 10 may be provided with two balancing parts 26 on the abutting surface, and the two balancing parts 26 are respectively located on both sides of the supporting plate 20. The existence of the balancing parts 26 can increase the contact area between the supporting plate 20 and the column 10 on the one hand, and reduce the deviation of the supporting plate 20 in the width direction on the other hand, so as to ensure the stability and balance of the supporting plate 20.

[0064] Continue to refer Figure 7 and Figure 8 The support plate 20 may be provided with a first hook portion 27, and the column 10 may be provided with a first matching portion 11, and the support plate 20 can be firmly connected to the column 10 by matching with the first hook portion 27. Further, when the column 10 is provided with a plurality of first matching portions 11, the support plate 20 can be operated to switch between a plurality of positions in the up-down direction to change the height of the support plate 20.

[0065] refer to Figure 7 The wall-mounted rack 100 may further include a positioning member 50, which is fixed to the wall. The column 10 is provided with a second hook portion 12, and the positioning member 50 is provided with a second matching portion 51. Through the second hook portion 12 and the second matching portion 51, the column 10 can be firmly connected to the positioning member 50, thereby being fixed to the wall.

[0066] It can be understood that the positioning member 50 can be constructed in various forms. For example, the positioning member 50 can be in a plate shape, and the present disclosure does not impose any particular limitation on this.

[0067] Continue to refer Figure 7 The wall-mounted object hanger 100 may further include a connector 61 and a hanging rod 71. The connector 61 is supported by the support plate 20 and can be operated to switch between multiple positions relative to the support plate 20, wherein the distances from the multiple positions to the wall are different. The hanging rod 71 is supported by the connector 61 on the lower side of the support plate 20 and is configured to hang items. In this way, clothes can not only be stored on the layer plate, but also be hung on the hanging rod 71 through a hanger, thereby increasing the storage form of the wall-mounted object hanger 100. The connector 61 can be operated to switch between multiple positions relative to the support plate 20, and the hanging rod 71 is supported by the connector 61, so the hanging rod 71 can also switch between multiple positions relative to the support plate 20, which makes the hanging range of the hanging rod 71 flexible and adjustable.

[0068] There are many ways to implement the object hanging rod 71, and the present disclosure does not impose any particular limitation thereto. For example, the object hanging rod 71 may be a continuous rod, or may be composed of a plurality of short rods, wherein the length of each short rod in the width direction needs to be greater than the spacing between two adjacent connecting members 61. In some other embodiments, the object hanging rod 71 may also be a rod that is retractable in the width direction, and the length may be adjusted according to the use requirements.

[0069] Continue to refer Figure 7 The wall-mounted object rack 100 may further include an object hanging hook 72, which is supported by the support plate 20 and configured to hang objects, and is operable to switch between multiple positions relative to the support plate 20. Therefore, the wall-mounted object rack 100 has more storage forms and flexible and adjustable object hanging space.

[0070] It should be understood that there are many ways to implement the wall-mounted rack of the present disclosure, and it should not be construed as being limited to the embodiments described above. Figures 9 to 13 , Fig.14A and Fig. 14B , the modified examples of the present disclosure are illustrated. It should be noted that the aforementioned embodiment and the following modified examples have some common elements. In the following modified examples, these elements will continue to use the figure numerals in the aforementioned embodiment to omit repeated description.

[0071] refer to Figures 9 to 13In the wall-mounted object rack 100a, the support plate 20a may be provided with a locking notch 25, the locking notch 25 is located on the side of the mounting notch 21 away from the corresponding column 10, the locking notch 25 is provided with a first edge 251 and a second edge 252 in sequence in a direction away from the column 10, the first edge 251 is provided with a first extension 253 extending toward the second edge 252, and the first extension 253 is provided with a first locking protrusion 254 protruding downward. The fixing member 40 may also be provided with a locking portion 44, the locking portion 44 includes a second extension 441 extending toward the column, and the second extension 441 is provided with a second locking protrusion 442 protruding upward.

[0072] Combination Fig.14A and Fig. 14B , the locking recess 25 receives the locking portion 44. As the fixing member 40 moves from the release position to the engagement position, the locking portion 44 moves from the unlocking position to the locking position in the locking recess 25. When the locking portion 44 is in the locking position, the second locking protrusion 442 is located on the side of the first locking protrusion 254 closer to the column 10, so that the second locking protrusion 442 abuts against the first locking protrusion 254. By judging whether the locking recess 25 receives the locking portion 44, the operator can determine whether the fixing member 40 has reached the engagement position, thereby judging whether the fixing member 40 is installed in place.

[0073] refer to Fig.10 and Fig.11 The fixing member 40 is provided with an open slot 45 which is open upwards. The open slot 45 is connected with the receiving slot 41 . The locking portion 44 is located in the open slot 45 . Fig.14A and Fig. 14B Since the locking portion 44 is located in the open groove, it is convenient for the operator to observe the matching between the second locking protrusion 442 and the first locking protrusion 254, thereby judging whether the fixing member 40 has reached the engaging position. On the other hand, since the open groove 45 is connected with the receiving slot 41, the second locking protrusion 442 is not blocked in the up and down directions, which is convenient for opening the mold during the injection molding process.

[0074] refer to Figures 9 to 13 , Fig.14A and Fig. 14BThe open groove 45 is formed with a first groove surface 451 and a second groove surface 452 on each side wall 43, the first groove surface 451 is closer to the column 10 than the second groove surface 452, the second extension portion 441 includes a crossbar portion 4411 and a pair of arm portions 4412, the pair of arm portions 4412 are respectively arranged on the two second groove surfaces 452 and extend toward the column 10, the ends of the pair of arm portions 4412 away from the second groove surface 452 are connected to the crossbar portion 4411, and the second locking protrusion 442 protrudes upward from the crossbar portion 4411. According to the above structure, the crossbar portion 4411 and the pair of arm portions 4412 and the two side walls 43 can close a part of the space in the fixing member 40, so that the locking portion 44 is hollowed out, so that the locking portion 44 is easy to deform, and the second locking protrusion 442 is pressed against the first locking protrusion 254. In this way, the operator can lock the fixing member 40 to the support plate 20 with less effort, thereby ensuring a good installation experience. On the other hand, since the locking portion 44 is hollow, it is easier to open the mold when manufacturing the fixing member 40 by injection molding, thereby reducing the manufacturing difficulty.

[0075] refer to Figures 9 to 11 Each of the two side walls 43 has a fixed block 431a extending toward the other side wall, and the two fixed blocks 431a are arranged at intervals in the depth direction, and the two fixed blocks 431a extend into the fixed groove 23a. The cooperation between the fixed groove 23a and the fixed block 431a can limit the displacement of the fixing member 40 in the up-down direction, so that it is stably placed on the support plate 20, thereby ensuring the stability of the structure. On the other hand, the two fixed blocks 431a that limit the fixing member 40 are arranged at intervals, and at the same time, they are each spaced from the engaging notch 42 of the limiting cross bar 31. Such position distribution makes the stress distribution inside the fixing member 40 more dispersed, which is beneficial to the stability of the structure.

[0076] refer to Fig.10 and Fig.11 Due to the presence of the open slot 45 and the fixed block 431a, if the guide portion 46 continues to be arranged in the depth direction, the distribution of the internal parts of the fixing member 40 will be too concentrated, which is not conducive to processing. Therefore, in the wall-mounted object rack 100a, the guide portion 46a can be configured to extend in the up-down direction.

[0077] It should be noted that the fixing member 40 a is cut to show its internal structure. Fig.11 Only one of the two guide portions 46 a is shown, and the other is opposite to the guide portion 46 a shown in the figure.

[0078] refer to Figures 9 to 11 and Fig.13The fixing member 40a may also be provided with two upwardly open viewing windows 48, the viewing windows 48 are interlinked with the receiving slot 41, and the projection of the fixing block 431a in the vertical direction completely falls into the projection of the viewing windows 48 in the vertical direction. In this way, the fixing block 431a can be unobstructed in the vertical direction, which is convenient for mold opening during injection molding.
