Description

[Technical Field]

[0001] This utility model relates to the technical field of household goods, specifically to a retractable and foldable hanging device. [Background technology]

[0002] In daily life, towel racks are household items commonly found in places such as bathrooms and kitchens, and are used to hang items such as towels, dustcloths, etc. Most conventional towel racks have a fixed structure, and their length and shape cannot be changed, which causes the following inherent drawbacks:

[0003] First, towel racks with fixed lengths cannot be flexibly adjusted according to the number of items to be hung or the size of the space. If there are only a few towels to hang, a towel rack that is too long will take up unnecessary space and look cluttered, and if there are many towels to hang, a towel rack that is too short will not meet the demand and will cause inconvenience in use.

[0004] Secondly, conventional fixed towel racks cannot free up space even when not in use, which reduces space utilization in small bathrooms or when used temporarily.

[0005] Currently, there are some foldable towel rails on the market, but their function is usually limited to folding as a whole, and it is not possible to adjust the effective hanging length according to actual needs when unfolded.Products with only a few extension functions have complicated adjustment mechanisms or require adjustment of the hanging rods one by one, which makes operation inconvenient and makes it difficult to achieve synchronous extension and contraction of all the hanging rods.

[0006] Therefore, there is a strong demand in this technical field for a hanging device that can be folded as a whole to save storage space, and also allows the hanging length to be easily and quickly adjusted, and allows all hanging rods to extend and retract in unison. Summary of the Invention

[0007] The technical problem that this utility model aims to solve is to overcome the drawbacks of the above-mentioned technologies and provide a retractable and foldable hanging device. [Means for solving the problem]

[Effects of the Invention]

[0013] The present invention has the following advantages over the prior art:

[0014] Regarding the extension and retraction function, the lower interlocking blocks and upper interlocking blocks of two adjacent sliders on the top and bottom intersect and fit together, so that when the lowest hanging rod is pulled outward along the slot, the upper interlocking block located at the bottom intersects with the lower interlocking block at the top, further driving the upper slider and hanging rod to move, thereby realizing the linked opening of all the hanging rods; and the mounting bases and upper interlocking blocks of two adjacent sliders on the top and bottom intersect and fit together, so that when the lowest hanging rod is pushed inward along the slot, the upper interlocking block located at the bottom intersects with the upper mounting base, further driving the upper slider and hanging rod to move, thereby realizing the linked retraction of all the hanging rods; the user can easily adjust the overall retraction length of multiple hanging rods by pulling out the appropriate number of hanging rods according to the actual usage situation.

[0015] Regarding the folding function, a lateral support beam is provided in each of the mounting grooves of the two lateral connecting parts, and the lateral support beam is rotatably connected to the mounting groove, allowing for opening and closing by rotation.

[0018] The retractable and foldable hanging device of the present invention will be described in more detail below with reference to drawings 1-9.

[0019] As shown in FIG. 1-9, the retractable and foldable hanging device comprises a rear beam 1, a horizontal connection 2, a horizontal support beam 3 and a plurality of hanging rods 4.

[0020] A horizontal connection part 2 is provided at each end of the rear girder 1. Specifically, an attachment groove 5 is provided on one side of the horizontal connection part 2 close to the rear girder 1, and the end of the horizontal connection part 2 is inserted into the attachment groove 5, and a fixed connection is achieved by means of screws or welding, etc., and attachment holes 13 are provided symmetrically on the rear girder 1, which are used to fix the entire hanging device to the wall surface using parts such as expansion screws.

[0021] A lateral support beam 3 is provided in each mounting groove 5 of the two lateral connectors 2, and the lateral support beam 3 can be connected to the mounting groove 5 via a rotation axis, allowing it to rotate relative to the rear girder 1 and the lateral connectors 2, thereby enabling the entire lateral support beam 3 and its associated structures to be opened and folded and closed (Figures 1-6 show the fully opened operating state of the hanger), and Figure 7 shows the folded and stored state of the hanger). The lateral support beam 3 is located inside the rear girder 1.

[0022] A cavity 6 is provided on one side of the horizontal support beam 3 adjacent to the rear girder 1, and a plurality of L-shaped partitions 7 are provided in the cavity 6 from top to bottom. These L-shaped partitions 7 are arranged in a stepped pattern, with their lengths decreasing from top to bottom. The lower part of the vertical part of the upper L-shaped partition 7 is connected to the adjacent lower L-shaped partition 7, thereby dividing the cavity 6 evenly into a plurality of slots 8 by the plurality of L-shaped partitions 7.

[0023] A slider 9 is provided in each slot 8, and the slider 9 is slidable along the slot 8. An attachment base 10 is provided at one end of each slider 9 adjacent to the rear beam 1. A plurality of the suspension rods 4 are arranged between the two horizontal support beams 3, and both ends of each suspension rod 4 are rotatably connected to two attachment bases 10 located on the same horizontal plane via a rotation axis, so that the suspension rod 4 can not only move along the slider 9 but also rotate around its own axis, which makes it easy to fold and store the horizontal support beams 3.

[0024] In order to achieve the linked extension and contraction of all the suspension rods 4, an upper interlocking block 11 is provided on one side of each mounting base 10 close to the slider 9, and a lower interlocking block 12 is provided on all sliders 9 located above the lowest slider 9, and the lower interlocking block 12 is located at one end of the slider 9 away from the mounting base 10.

[0025] A stopper block 16 is provided at one end of the horizontal support beam 3, close to the horizontal connection part 2 at the inner upper end thereof, and the stopper block 16 engages with the upper interlocking block 12 provided on the top slider 9, and is used to position the top slider 9.

[0026] Specifically, the lower interlocking block 11 and the upper interlocking block 12 of two adjacent sliders 9 on the top and bottom interlock and fit together, that is, these two block bodies interlock and fit together vertically, and the upper interlocking block 12 can abut against the lower interlocking block 11. As a result, when the lowest suspension rod 4 is pulled outward along the slot 8, the upper interlocking block 12 located at the bottom abuts against and pushes the upper lower interlocking block 11, further driving and moving the upper slider 9 and suspension rod 4, thereby realizing the linked opening of all suspension rods 4.

[0027] After all the suspension rods 4 are fully pulled out and released, one end of the lowest slider 9 abuts against the end wall of the slot 8 at one end away from the rear beam 1 in which it is located, and the upper interlocking block 12 provided on the top slider 9 abuts against the stopper block 16, thereby positioning the top slider 9 to prevent it from sliding left or right.

[0028] The mounting bases 10 and upper interlocking blocks 12 of two adjacent sliders 9 on the top and bottom are interlocked and fitted together, i.e., the mounting bases 10 and upper interlocking blocks 12 are also interlocked and fitted together vertically, and the upper interlocking blocks 12 can abut against the mounting bases 10. As a result, when the lowest hanging rod 4 is pushed and pulled inward along the slots 8, the upper interlocking block 12 located at the bottom abuts against and pushes the upper mounting base 10, further driving and moving the upper sliders 9 and hanging rods 4, thereby realizing the linked storage of all hanging rods 4.

[0029] For ease of operation, a handle 14 is provided on one end of the lowermost slider 9 remote from the mounting base 10 .

[0030] A horizontal bar 15 is provided below the rear girder 1, and both ends of the horizontal bar 15 are connected to two horizontal connection parts 2, so that towels or the like can be hung on the horizontal bar 15 even when the horizontal support beam 3 is folded and stored, which is relatively convenient.

[0031] When specifically implementing this utility model,

[0032] The deployment and contraction process will now be described.

[0033] When it is necessary to use it, the user holds the two handles 14 with both hands, or holds both ends of the lowest suspension rod 4 with both hands, and pulls the lowest suspension rod 4 and the lowest slider 9 connected to it outward (away from the rear beam 1). During the movement process, the upper interlocking block 12 on the lowest slider 9 abuts against and pushes the lower interlocking block 11 of the slider 9 adjacent above, thereby moving all the sliders 9 adjacent above outward together. Similarly, the movement of the adjacent slider 9 above pushes the sliders 9 above it through the upper interlocking block 12 attached to it, finally realizing the linked deployment of all the sliders 9 and suspension rods 4.

[0034] The user can select the number of hanging rods 4 to be pulled out according to their needs. For example, if two hanging rods 4 are needed, they pull out two, and if four are needed, they pull out four, thereby adjusting the overlap length of all the pulled-out hanging rods 4 and avoiding too many pulled-out hanging rods 4 taking up unused space.

[0035] The storage process will be explained.

[0036] When it is necessary to stow the structure, the lowest suspension rod 4 or the two handles 14 are pushed inward (towards the rear girder 1) with both hands, the lowest slider 9 moves inward, and the upper interlocking block 12 mounted on it abuts against the mounting base 10 of the adjacent slider 9 above and pushes it, pulling and moving all the adjacent sliders 9 above inward. In the same way, the interlocking effect is transmitted stepwise upward, causing all the suspension rods 4 to converge synchronously, and finally all the suspension rods 4 are closely aligned in front of the rear girder 1 from top to bottom, achieving complete stowage.

[0037] The folding process will now be described.

[0038] When it is necessary to store the entire hanging device to save space, first store all the hanging rods 4 using the above method. Then, the user grasps the horizontal support beams 3 and rotates them inward around the connection points with the horizontal connectors 2, folding the two horizontal support beams 3 to the front of the rear girder 1 for storage. In this way, the two horizontal support beams 3 are parallel to the rear girder 1 and are in close contact with it (as shown in Figure 7), greatly reducing the amount of space occupied.
