Description

Technical Field

[0001] This invention relates to a ceiling-mounted clothes drying rack, and more particularly to a ceiling-mounted clothes drying rack that can move along a circular track. The clothes drying rack includes a main unit that can move along the circular track and a drying rod suspended below the main unit. It can be selectively moved to a suitable indoor space to meet the layout requirements and lighting changes of the indoor space. Background Technology

[0002] The clothes drying rack includes a main unit installed on the ceiling and a height-adjustable drying rod. The main unit is equipped with a wire rope drive device. The lower end of the wire rope leading from the wire rope drive device is connected to the drying rod. The wire rope is retracted and extended to drive the raising and lowering of the drying rod.

[0003] A concealed clothes drying rack is available, comprising a main unit with a power unit, a panel assembly with grooves, and a height-adjustable drying rod.

[0004] For example, the concealed single-pole clothes drying rack in patent application CN113265857A and the concealed clothes drying rack with lighting function in patent application CN113832680A both disclose a concealed clothes drying rack and the assembly structure of its various components. In both patents, the casing has a protective plate, the concealed box has a top plate, and the connection between the top plate of the casing and the protective plate of the concealed box realizes the connection between the casing and the concealed box.

[0005] The authorization announcement number CN212152846U discloses a horizontally rotating clothes drying rack that can change the light-receiving surface of clothes to make them dry quickly and synchronously. It is a non-concealed clothes drying rack.

[0006] Market research and patent searches reveal that most existing ceiling-mounted clothes drying racks are installed in fixed positions on the ceiling and can only raise and lower the drying rod. No concealed ceiling-mounted clothes drying racks that can move along a circular track have been found. However, as people's demands for quality of life continue to rise, the need for smart homes is growing, leading to increasing demands for the functions and application scenarios of ceiling-mounted clothes drying racks. Especially when ceiling-mounted clothes drying racks are installed in bedrooms, dedicated cloakrooms, laundries, clothing stores, photo studios, and other similar locations, users are no longer satisfied with fixed installations.

[0036] The first hinge hole of the first housing and the second hinge hole corresponding to the position of the second housing are hinged through the host hinge assembly to realize the hinge between the first mobile host and the lifting host, and the hinge between the lifting host and the second mobile host.

[0037] The preferred technical solution adopted by the present invention to solve the above-mentioned technical problems is as follows: the host hinge assembly includes a hinge piece with two through holes and two hinge pins.

[0038] The two through holes of the hinge piece are aligned with the first hinge hole and the second hinge hole corresponding to the position, respectively. The two hinge pins pass through a through hole and the aligned first hinge hole or the second hinge hole, respectively, to realize the hinge between the first housing and the second housing.

[0039] The preferred technical solution adopted by the present invention to solve the above-mentioned technical problems is as follows: the drying rod assembly is formed by hinged together in sequence from front to back by a first drying rod unit and a second drying rod unit located at both ends, and at least one third drying rod unit located between the first drying rod unit and the second drying rod unit.

[0040] Each drying rod unit has several drying holes distributed along its length.

[0041] The first drying rod unit and the second drying rod unit are each provided with a rope seat. The rope seat of the first drying rod unit is connected to the first steel wire rope, and the rope seat of the second drying rod unit is connected to the second steel wire rope.

[0044] One end of the third drying rod unit is a first hinge end, and the other end is a second hinge end;

[0045] The two first hinge ends and the two second hinge ends are hinged together by a drying rod hinge assembly, so that when the first mobile host, the lifting host and the second mobile host can turn and move along the annular host track, the first wire rope and the second wire rope can drive the drying rod assembly and the host device on the annular host track to turn and move synchronously.

[0046] The preferred technical solution adopted by the present invention to solve the above-mentioned technical problems is as follows: the drying rod hinge assembly includes a first hinge member, a second hinge member, and a pivot pin;

[0047] The first hinge and the second hinge have hinge portions on their back sides; the hinge portion of the first hinge is located above its back side, and the hinge portion of the second hinge is located below its back side.

[0048] The hinge part is a hollow cylinder, and a through pin hole is provided in the central axis of the cylinder.

Similarly, "first," "second," and "third" are only for ease of understanding and have no other directional meaning, and should not be considered as limitations on this invention.

[0074] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "set up," "connect," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0075] like Figures 1 to 3The image shows a concealed ceiling-mounted clothes drying system S, which can move along a circular track, provided by the present invention. It includes a ceiling 100 installed below the building's ceiling, a main unit 200, and a drying rod assembly 300. A circular main unit track 110 is laid within the inner space of the ceiling 100, and an annular groove 120 connecting the drying area is formed on the ceiling 100 below the circular main unit track 110.

[0076] like Figure 4 and Figure 5 As shown, the main unit 200 is concealed inside the ceiling 100 and includes a first mobile main unit 210 equipped with a first power source 211, a lifting main unit 230, and a second mobile main unit 220 equipped with a second power source 221. The first mobile main unit 210 is hinged to the lifting main unit 230, and the lifting main unit 230 is hinged to the second mobile main unit 220, so that the first mobile main unit 210, the lifting main unit 230, and the second mobile main unit 220 can rotate and move along the annular main unit track 110.

[0077] The drying rod assembly 300 is formed by hinged together in sequence from front to back a first drying rod unit 310 and a second drying rod unit 320 located at both ends, and a third drying rod unit 330 located between the first drying rod unit 310 and the second drying rod unit 320.

[0078] A wire rope winding and unwinding device 231 is installed inside the lifting host 230. The first wire rope 241 led out from the wire rope winding and unwinding device 231 enters the first moving host 210 horizontally and passes vertically downward through the annular groove 120 to connect with the first drying rod unit 310. The second wire rope 242 led out from the wire rope winding and unwinding device 231 enters the second moving host 220 horizontally and passes vertically downward through the annular groove 120 to connect with the second drying rod unit 320.

[0079] In use, the first power source 211 in the first mobile host 210 and the second power source 221 in the second mobile host 220 can drive the entire host device 200 to rotate clockwise or counterclockwise along the annular host track 110 laid inside the ceiling 100, or stop at any position on the annular host track 110. Under the traction of the first steel wire rope 241 and the second steel wire rope 241, the drying rod assembly 300 can rotate synchronously with the host device 200 on the annular host track 110.

[0080] like Figure 1 and Figure 2As shown, taking the turning movement process of the first mobile host 210 at the forefront of the forward direction as an example: when the host device 200 moves to the turning point of the circular host track 110, the first mobile host 210 first passes through the turning point; then, the hinge joint between the first mobile host 210 and the lifting host 230 rotates along the turning point of the circular host track 110, so that the lifting host 230 can smoothly pass through the turning point; subsequently, the hinge joint between the lifting host 230 and the second mobile host 220 rotates along the turning point of the circular host track 110, so that the second mobile host 220 can smoothly pass through the turning point. Thus, the host device 200 as a whole turns smoothly.

[0081] Synchronously with the turning process of the main unit 200: Under the traction of the first wire rope 241 and the second wire rope 242, the drying rod assembly 300 and the main unit 200 arrive at the turning point simultaneously. The first drying rod unit 310 passes through the turning point first; then, the first drying rod unit 310 pulls the third drying rod unit 330 to the turning point, and the hinge point between the two rotates to allow the third drying rod unit 330 to pass through the turning point smoothly; subsequently, the third drying rod unit 330 pulls the second drying rod unit 320 to the turning point, and the hinge point between the two rotates to allow the second drying rod unit 320 to pass through the turning point smoothly. Thus, the drying rod assembly 300 and the main unit 200 turn smoothly and synchronously as a whole.

[0082] The turning and moving process when the second mobile host 220 is at the forefront of the forward direction is similar and will not be described in detail here. Furthermore, the concealed ceiling-mounted clothes drying system S, which can move along a circular track, provided by this invention, has a main unit 200 that can turn and move along the circular main host track 110, driving the drying rod assembly 300 to turn and move synchronously, thereby realizing the cyclic turning and moving function of the ceiling-mounted clothes drying machine. Users can turn and move the ceiling-mounted clothes drying machine to any position on the circular main host track 110 according to their preferences and the layout of the room, thus flexibly changing the position of the clothes hanging and meeting various practical needs in different application scenarios.

[0083] Additionally, under the traction of the wire rope retraction device 231 within the lifting host 230, the entire drying rack assembly 300 can be raised and lowered and stop at a certain height. When the drying rack assembly 300 descends to a suitable height, it is convenient for users to hang clothes on the drying rack assembly 300. Figure 3As shown, steel wire ropes 241 and 242 can further pull the drying rod assembly 300 up into the annular groove 120, thereby concealing the entire ceiling clothes drying machine, including the main unit 200 and the drying rod assembly 300, within the ceiling 100. On the one hand, after the user finishes hanging the clothes, the drying rod assembly 300 can be raised together with the clothes hanging on it until it reaches the ceiling 100, freeing up the lower space of the room and not affecting the user's daily activities. On the other hand, with the drying rod assembly 300 hidden in the annular groove 120, the entire ceiling clothes drying machine is concealed within the ceiling 100, creating the visual effect that the clothes appear to be hanging directly on the ceiling, making the environment aesthetically pleasing and tidy.

[0084] like Figure 6 and Figure 7 As shown, the annular main track 110 includes four straight track sections 111 (front, back, left, and right) and four curved track sections 112 that connect to the straight track sections 111. The annular main track 110 has an annular horizontal top wall 130, which is formed by a series of rectangular beams 131 and curved beams 132 joined end-to-end. These beams are fixed to the inner space of the suspended ceiling 100 below the building's ceiling by a series of ceiling bolts 133 arranged along the annular horizontal top wall 130 of the annular main track 110. The rectangular beams 131 form the portion of the annular horizontal top wall 130 corresponding to the straight track section 111, and the curved beams 132 form the portion of the annular horizontal top wall 130 corresponding to the curved track sections 112.

[0085] It should be understood that the shape of the annular main track 110 and the assembly method of the beam splicing provided in this embodiment cannot be used to limit the protection scope of the concealed ceiling clothes drying system S that can move along the annular track provided by the present invention. Typically, the annular main track 110 can also be circular, polygonal with arc corners, etc., and the annular horizontal top wall 130 can also be integral.

[0086] It should be noted that the shape of the annular main track 110 and the assembly method of the beam splicing provided in this embodiment have the following two advantages: First, the shape of the four straight rail areas 111 and the four arc-shaped rail areas 112 of the annular main track 110 provided in this embodiment can provide users with as many straight rail areas 111 as possible to meet the user's habit and need to hang clothes neatly. The four arc-shaped rail areas 112 can flexibly turn and connect with adjacent straight rail areas 111, so that the main device 200 and the clothes drying assembly 300 can turn smoothly and continuously, avoiding the clothes from shaking or even falling off due to jamming during turning.

[0087] Secondly, in this embodiment, the rectangular beam frame 131 and the arc-shaped beam frame 132 are spliced ​​end to end to form a ring-shaped horizontal top wall 130, which makes the splicing and assembly of the ring-shaped main engine track 110 more flexible. It can be spliced ​​and assembled into ring-shaped main engine tracks 110 of different shapes according to different ceiling sizes, ceiling shapes and even user aesthetic preferences.

[0088] like Figures 8 to 11 As shown, the first mobile host 210 or the second mobile host 220 includes a first housing 10, a pair of adjacent horizontal guide wheels 11, and a vertical guide wheel 12. The pair of horizontal guide wheels 11 are located on the side of the first housing 10 closer to the lifting host 230, and the vertical guide wheel 12 is located on the side of the first housing 10 away from the lifting host 230.

[0089] The first wire rope 241 passes horizontally between adjacent horizontal guide wheels 11 inside the first housing 10 of the first mobile host 210, passes downwards over the vertical guide wheel 12, and then passes vertically downwards through the rope hole 13 on the first housing 10 to connect with the first drying rod unit 310. The second wire rope 242 passes horizontally between adjacent horizontal guide wheels 11 inside the first housing 10 of the second mobile host 220, passes downwards over the vertical guide wheel 12, and then passes vertically downwards through the rope hole 13 on the first housing 10 to connect with the second drying rod unit 320.

[0090] When the wire rope retraction device 231 inside the lifting host 230 pulls the first wire rope 241 or the second wire rope 242 to extend or retract, the two adjacent horizontal guide wheels 11 rotate in opposite directions according to the direction of movement of the wire rope between them. On the one hand, this prevents the wire rope from deviating from its length direction on the horizontal plane, and on the other hand, it plays a horizontal auxiliary guiding role, making the extension or retraction of the wire rope smoother.

[0091] The vertical guide wheel 12 rotates in the same direction as the wire rope extends or retracts. On the one hand, it guides the wire rope from the horizontal direction to the vertical direction, so that it can connect downward to the clothes drying assembly 300. On the other hand, it reduces the friction between the wire rope and the vertical guide wheel 12 when the wire rope extends or retracts, making the wire rope smoother to extend and retract.

[0092] like Figure 5 , Figure 10 and Figure 11As shown, the first power source 211 or the second power source 221 includes a motor 251 and a drive wheel 252, with the drive wheel 252 located above the first housing 10. The annular main unit track 110 includes a main unit track 113 accommodating the main unit 200 and a wheel track 114 for the drive wheel 252 to move, with the wheel track 114 located above the main unit track 113. The motor 251 drives the drive wheel 252 to rotate and move within the wheel track 114, thereby causing the first mobile main unit 210, the lifting main unit 230, and the second mobile main unit 220 to rotate and move within the main unit track 113.

[0093] Specifically, such as Figure 15 and Figure 16 As shown, the wheel track 114 has an inverted U-shaped cross-section, and its top wall is part of the annular horizontal top wall 130 of the annular main unit track 110. Two annular support surfaces 115 extend horizontally from the lower edges of its two side walls towards its centerline, with an annular through groove 116 between the two annular support surfaces 115. The drive wheel 252 is mounted on the two annular support surfaces 115. The motor shaft 253 of the motor 251 passes through the annular through groove 116 and connects to the drive wheel 252 above, driving the drive wheel 252 to rotate and move within the wheel track 114. The space between the wheel track 114 and the ceiling 100 below it forms the main unit track 113, which accommodates the main unit 200.

[0094] like Figure 8 and Figure 9 As shown, the first housing 10 is composed of a concave bottom shell 14 and an inner liner shell 15 fixed inside the bottom shell 14. A motor housing 16 with a cavity 16a is vertically arranged in the center of the inner liner shell 15. The cavity 16a of the motor housing 16 is adapted to the shape of the motor 251 to accommodate the motor 251.

[0095] A shaft hole 16b is formed at the top of the motor housing 16. The motor shaft 253 of the motor 251 passes through the shaft hole 16b and then through the annular groove 116 to connect with the drive wheel 252 above. Several connecting plates 17 are radially distributed between the side wall of the motor housing 16 and the side wall of the inner shell 15, and each connecting plate 17 is vertically arranged. On the one hand, the connecting plates 17 can serve as a connection and support between the motor housing 16 and the inner shell 15. On the other hand, the structure of the inner shell 15 with radially distributed and vertically arranged connecting plates 17 is conducive to heat dissipation of the motor 251 and extends the service life of the motor 251.

[0096] like Figure 8 , Figure 12 and Figure 13As shown, the lifting host 230 includes a second housing 20 and a lifting mechanism 21 disposed within the second housing 20. A wire rope winding and unwinding device 231 is disposed within the lifting mechanism 21. The top and bottom of the first housing 10 are provided with a first hinge hole 31 near the end of the lifting host 230, and the top and bottom of the second housing 20 are provided with second hinge holes 32 near both ends of the first moving host 210 and the second moving host 220.

[0097] like Figure 14 As shown, the first hinge hole 31 of the first housing 10 of the first mobile host 210 and the second hinge hole 32 corresponding to the position of the second housing 20 of the lifting host 230 are hinged by the host hinge assembly ZJ. That is, the first hinge hole 31 at the top of the first housing 10 of the first mobile host 210, near the lifting host 230, and the second hinge hole 32 at the top of the second housing 20 of the lifting host 230, near the first mobile host 210, are hinged by the host hinge assembly ZJ; the first hinge hole 31 at the bottom of the first housing 10 of the first mobile host 210, near the lifting host 230, and the second hinge hole 32 at the bottom of the second housing 20 of the lifting host 230, near the first mobile host 210, are hinged by the host hinge assembly ZJ.

[0098] Similarly, the first hinge hole 31 of the first housing 10 of the second mobile host 220 and the second hinge hole 32 corresponding to the position of the second housing 20 of the lifting host 230 are hinged by the host hinge assembly ZJ, which will not be described in detail here. Thus, the first mobile host 210 is hinged to the lifting host 230, and the lifting host 230 is hinged to the second mobile host 220.

[0099] like Figure 14 As shown, the main unit hinge assembly ZJ includes a hinge piece ZJ1 with two through holes ZJ2 and two hinge pins ZJ3. The two through holes ZJ2 of the hinge piece ZJ1 are respectively aligned with the first hinge hole 31 and the second hinge hole 32 corresponding to the position. The two hinge pins ZJ3 pass through one of the through holes ZJ2 and the first hinge hole 31 or the second hinge hole 32 aligned with the through hole ZJ2, thereby realizing the hinge between the first housing 10 and the second housing 20.

[0100] like Figure 17 As shown, the drying rod assembly 300 is formed by hinged together in sequence from front to back a first drying rod unit 310 and a second drying rod unit 320 located at both ends, and a third drying rod unit 330 located between the first drying rod unit 310 and the second drying rod unit 320. Each drying rod unit has several drying holes H distributed along its length for hanging clothes.

[0101] One end of the first drying rod unit 310 is a free end D0, and the other end is a first hinged end D1. One end of the second drying rod unit is a free end D0, and the other end is a second hinged end D2. One end of the third drying rod unit 330 is a first hinged end D1, and the other end is a second hinged end D2.

[0102] The two first hinge ends D1 and the two second hinge ends D2 are respectively hinged by the drying rod hinge assembly LJ. That is, the first hinge end D1 of the first drying rod unit 310 and the first hinge end D1 of the third drying rod unit 330 are hinged by the drying rod hinge assembly LJ; the second hinge end D2 of the second drying rod unit and the second hinge end D2 of the third drying rod unit 330 are hinged by the drying rod hinge assembly LJ.

[0103] Each of the first drying rod unit 310 and the second drying rod unit 320 is equipped with a rope seat 40. The rope seat 40 of the first drying rod unit 310 is connected to the first steel wire rope 241, and the rope seat 40 of the second drying rod unit 320 is connected to the second steel wire rope 242. Thus, when the first moving host 210, the lifting host 230, and the second moving host 220 rotate and move along the annular host track 110, the first steel wire rope 241 and the second steel wire rope 242 can drive the drying rod assembly 300 to rotate and move synchronously with the host device 200 on the annular host track 110.

[0104] In other embodiments, the drying rod assembly 300 can be expanded according to the user's actual needs, that is, it can include two or more third drying rod units 330 so that the user can hang more clothes.

[0105] like Figure 18 As shown, the drying rod hinge assembly LJ includes a first hinge LJ1, a second hinge LJ2, and a pivot pin LJ3. The back of the first hinge LJ1 and the second hinge LJ2 have hinge portions LJ4. The hinge portion LJ4 of the first hinge LJ1 is located above its back, and the hinge portion LJ4 of the second hinge LJ2 is located below its back.

[0106] The hinge part LJ4 is a hollow cylinder with a through pin hole LJ5 in the central axis. The hinge parts LJ4 of the first hinge member LJ1 and the second hinge member LJ2 are joined together vertically, and the pin LJ3 passes through the two pin holes LJ5 to realize the hinge between the drying rod units.

[0107] It should be noted here that for two adjacent hinged ends to be hinged, a first hinge LJ1 should be installed at one end and a second hinge LJ2 should be installed at the other end, so that the hinge parts LJ4 of the two hinges can be mated together, and the two pin holes LJ5 can be aligned vertically so that the pin LJ3 can pass through smoothly.

[0108] For example, such as Figure 17As shown, in this embodiment, the first hinge end D1 of the first drying rod unit 310 and the second hinge end D2 of the second drying rod unit are equipped with a first hinge member LJ1, and both the first hinge end D1 and the second hinge end D2 of the third drying rod unit 330 are equipped with second hinge members LJ2. Of course, as long as the above-mentioned conditions for upper and lower mating are met, other installation methods can also be adopted. For example, the second hinge end D2 of the second drying rod unit is equipped with a second hinge member LJ2, and the second hinge end D2 of the third drying rod unit 330 is equipped with a first hinge member LJ1. This method of setting the drying rod hinge assembly LJ provides convenience for users to expand and splice the drying rod assembly 300.
