Description

Technical Field

[0001] This invention relates to the field of toilet accessories, and more specifically to a quick-release bracket assembly and a toilet seat assembly having the quick-release bracket assembly. Background Technology

[0002] Toilets are sanitary appliances used in building water supply and drainage materials, widely used in homes, office buildings, and other places. A toilet generally includes a toilet seat, a lid assembly, and a flushing mechanism. To achieve quick removal and washing of the toilet lid, existing technologies have developed quick-release structures for the lid assembly. However, most toilet lids require tools for removal and cannot be disassembled without them.

[0003] For example, CN216984701U discloses a quick-install toilet seat, in which the toilet seat and toilet body are installed via a hinge. The hinge includes a damper and a hinge body. The top of the hinge body is connected to the damper, and the bottom of the hinge body extends into the mounting hole of the toilet body. The hinge body includes a main rotating shaft and an elastic expansion body. Rotating the main rotating shaft controls the expansion and contraction of the elastic expansion body within the mounting hole. When disassembly or reassembly is required, the main rotating shaft is driven to rotate by a laterally inserted drive rod, thereby causing the elastic expansion body to expand or recover. The drive rod is located between the toilet seat and the toilet seat. During operation, it is necessary to reach between the toilet seat and the toilet seat to control the drive rod. The space is small and difficult to operate, and this position is a blind spot for cleaning, which is prone to bacterial growth, and the drive rod is easily contaminated when operating it. Summary of the Invention

[0004] To address these issues, the present invention provides a quick-release support assembly and a toilet seat assembly having the quick-release support assembly.

[0005] To achieve the above objectives, the technical solution provided by the present invention is as follows:

[0006] A quick-release support assembly includes a support, a screw, a fastening nut, an expansion body, an adjusting block, and a flip hinge. The screw passes through the support. The adjusting block, expansion body, and fastening nut are sequentially assembled onto the screw from top to bottom. The fastening nut is locked to the screw. The adjusting block abuts against the support. The expansion body is confined between the fastening nut and the adjusting block. The flip hinge is disposed on the upper surface of the support and connected to the screw via a pivot. The flip hinge has a protrusion. When the flip hinge is flipped so that the protrusion abuts against the support, it causes the screw to lift upward, thereby driving the expansion body to expand.

[0007] Furthermore, the support includes a sleeve and buckles connected to the left and right sides of the sleeve. Two sets of screws, fastening nuts, expansion bodies and adjusting blocks are provided and respectively assembled on the left and right buckles. The number of flip hinges is one. The flip hinge abuts against the two buckles and is connected to the screws on the two buckles through a rotating shaft.

[0008] Furthermore, the support includes a sleeve and an integrated buckle connecting the sleeve. Two sets of screws, fastening nuts, expansion bodies, and adjusting blocks are provided and respectively assembled on the left and right sides of the integrated buckle. The number of flip hinges is one. The flip hinge abuts against the integrated buckle and is connected to two screws through a pivot.

[0009] Furthermore, the flip hinge includes a flip plate and a cylinder connected to one side of the flip plate. The cylinder has a central shaft hole, and the rotating shaft is fitted into the central shaft hole of the cylinder. The cylinder is higher than the upper surface of the flip plate, and the part of the flip plate located below the cylinder forms the protrusion.

[0010] Furthermore, a plug is provided at the end of the central shaft hole.

[0011] Furthermore, the insertion end of the plug forms an inclined guide surface.

[0012] Furthermore, the protrusion is an arc-shaped protrusion, and the hinge has an abutting edge connecting the protrusion. When the abutting edge of the hinge abuts against the support, the expansion body is compressed and expanded. The tangent line at the connection position between the protrusion and the abutting edge is defined as a horizontal tangent line, and the abutting edge is inclined to the horizontal tangent line and closer to the pivot than the horizontal tangent line.

[0013] Furthermore, the adjustment block is an adjustment shim or is composed of multiple adjustment shims stacked together; when fitting toilet seats of different thicknesses, the optimal installation can be achieved by increasing or decreasing the number of adjustment shims.

[0014] Furthermore, a pad is mounted on the support, the screw is also inserted through the pad, an anti-slip pad is mounted on the bottom of the pad, and the adjusting block abuts against the bottom of the pad.

[0015] Furthermore, the support is also provided with a limiting mechanism, and the hinge is provided with a hook that cooperates with the limiting mechanism. When the hinge is flipped so that the protrusion abuts against the support, the hook engages with the limiting mechanism and is fixed. The limiting mechanism has a pressing rod for releasing the fixation.

[0016] Furthermore, the support is provided with an installation cavity, and the limiting mechanism is assembled in the installation cavity of the support. The support has an upper opening and a side opening communicating with the installation cavity. The limiting mechanism includes a spring and a pressing rod. The pressing rod has a limiting rod. The pressing rod is assembled laterally. The spring is assembled between the pressing rod and the inner wall of the installation cavity. When the hinge flips, its hook is inserted from the upper opening and locked onto the limiting rod. The spring applies a retaining force to the pressing rod to engage with the hook. The pressing rod is driven by an external force to disengage the limiting rod from the hook.

[0017] Furthermore, the pressing rod and the pressing key are an integrally connected structure.

[0018] A toilet seat assembly includes a support assembly and a cover plate and a seat ring connected to the support assembly, wherein the support assembly is the quick-release support assembly described above.

[0019] The technical solution provided by this invention has the following beneficial effects:

[0020] The quick-release support assembly provided in this solution features a flip hinge on the upper surface of the support. Flipping the hinge raises or lowers the screw, causing the expansion body to expand and enabling quick installation. When the hinge flips until the protrusion disengages from the support, the screw lowers, the expansion body returns to its original position, and the toilet seat is released, achieving quick disassembly. This method exposes the flip hinge, avoiding areas prone to contamination, and offers convenient, faster, and more stable assembly and disassembly without the need for tools.

[0039] To further illustrate the various embodiments, the present invention provides accompanying drawings. These drawings are part of the disclosure of the present invention, primarily used to illustrate the embodiments and to explain the operating principles of the embodiments in conjunction with the relevant descriptions in the specification. With reference to these drawings, those skilled in the art should be able to understand other possible implementations and the advantages of the present invention. Components in the drawings are not drawn to scale, and similar component symbols are generally used to represent similar components.

[0040] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0041] Example 1

[0042] Reference Figures 1 to 9 As shown, this embodiment provides a quick-release support assembly 100, including a support 10, a screw 31, a fastening nut 32, an expansion body 33, an adjusting block 34, and a flip hinge 20. The screw 31 passes through the support 10. In this embodiment, the support 10 has a through hole 124, and the screw 31 passes through the through hole 124 through the bottom of the support 10. The adjusting block 34, the expansion body 33, and the fastening nut 32 are sequentially assembled onto the screw 31 from top to bottom. Figure 2 , Figure 3 As shown, the adjusting block 34, the expansion body 33, and the fastening nut 32 are located below the support 10. The fastening nut 32 is locked to the screw 31, the adjusting block 34 abuts against the support 10, and the expansion body 33 is confined between the fastening nut 32 and the adjusting block 34. The flip hinge 20 is disposed on the upper surface 101 of the support 10 and connected to the screw 31 through the rotating shaft 24. The flip hinge 20 has a protrusion 23, similar to a cam structure. When the flip hinge 20 flips to the point where the protrusion 23 abuts against the support 10, the rotating shaft 24 is lifted, thereby driving the screw 31 to lift upward. When the screw 31 is lifted upward, the fastening nut 32 will lift along with the screw 31, while the adjusting block 34 is held in place by the support 10. The lifting of the fastening nut 32 will compress the expansion body 33, thereby driving the expansion body 33 to expand. When the hinge 20 flips to the point where the protrusion 23 disengages from the support 10, the shaft 24 and screw 31 descend, and the fastening nut 32 also descends. The expansion body 33 loses the compression and repositioning caused by the fastening nut 32.

[0043] like Figure 11 , Figure 12 As shown, when the quick-release support assembly 100 is used on the toilet seat 200, the screw 31, fastening nut 32, expansion body 33, and adjusting block 34 are inserted into the mounting hole 201 of the toilet seat 200. The support 10 and the flip hinge 20 are above the toilet seat 200. After installation, the expansion body 33 is expanded or reset by flipping the flip hinge 20. Figure 11 As shown, the expansion body 33 expands within the mounting hole 201 to secure the quick-release bracket assembly 100 to the toilet seat 200, achieving quick installation. Figure 12 As shown, after the expansion body 33 retracts and resets, the fixation is released, achieving quick disassembly. Using this method, the hinge 20 is exposed, avoiding areas prone to contamination, and operation is convenient, making disassembly and assembly faster and more stable. No tools are required.

[0044] Continue to refer to Figure 10As shown, this embodiment also provides a toilet seat assembly, including a support assembly and a cover plate 51 and a seat ring 52 connected to the support assembly. Specifically, the support assembly is the quick-release support assembly 100 described above.

[0045] Furthermore, in this embodiment, the support 10 includes a sleeve 11 and buckles 12 connected to the left and right sides of the sleeve 11. The sleeve 11 and the buckles 12 on both sides are integrally connected structures, and their material is plastic, which can be integrally injection molded by injection molding, making the manufacturing process simple. The sleeve 11 is used to connect the cover plate 51 and the seat ring 52. Two sets of screws 31, fastening nuts 32, expansion bodies 33, and adjusting blocks 34 are provided and respectively assembled on the left and right buckles 12. There is one flip hinge 20, which abuts against the two buckles 12 and is connected to the screws 31 on the two buckles 12 through a rotating shaft 24. In this specific embodiment, the flip hinge 20 is connected to the screws 31 on the two buckles 12 respectively through two coaxially arranged rotating shafts 24. The fixation is more secure by two sets of screws 31 with expansion bodies 22, and the toilet seat assembly is less prone to swaying. Of course, in other embodiments, the structure of the support 10 is not limited to this. For example, a single buckle 12 structure or two or more buckle 12 structures can be used. When multiple buckles 12 are used, each buckle 12 can be connected to the screw 31 by a flip hinge 20, achieving simultaneous fixing or unfixing. The structure is simple and the operation is more convenient.

[0046] Specifically, in this embodiment, the flip hinge 20 includes a flip plate 21 and a cylinder 22 connected to one side of the flip plate 21. The flip plate 21 and the cylinder 22 are integrally connected and made of plastic. Like the support 10, they can also be integrally injection molded. The flip plate 21 is used for handheld operation to flip the hinge 20. The cylinder 22 has a central shaft hole 221, and the rotating shaft 24 is fitted into the central shaft hole 221 of the cylinder 22. The cylinder 22 is higher than the upper surface 212 of the flip plate 21, and the portion of the flip plate 21 located below the cylinder 22 forms the protrusion 23. Specifically, when the flip hinge 20 is flipped so that the flip plate is flat against the support 10 (defined as the first position), the protrusion 23 abuts against the support 10, and the cylinder 22 is lifted as a whole, thereby lifting the screw 31 and the fastening nut 32 to achieve fixed installation. When the hinge 20 is flipped so that the flap is perpendicular to the support 10 (defined as the second position), the protrusion 23 disengages from the support 10 and is partially pressed against the support 10 by the cylinder 22. The screw 31 and the fastening nut 32 descend, and the expansion body 33 loses its compression and retracts to its original position.

[0047] Meanwhile, thanks to the protrusion 23, the hinge 20 can be well maintained in both the first and second positions.

[0048] A plug 25 is provided at the end of the central shaft hole 221 to seal the rotating shaft 24. This design effectively prevents the built-in rotating shaft 24 from retracting or even falling off, provides good protection for the rotating shaft 24, and is aesthetically pleasing. Furthermore, the end of the plug 25 forms an inclined guide surface 251, which provides good guidance during insertion, allowing the plug 25 to be inserted smoothly.

[0049] The adjusting block 34 is composed of multiple adjusting pads 341 stacked together; in this embodiment, there are three. The number of adjusting pads 341 can be varied to accommodate toilet seats 200 of different thicknesses, thus improving applicability. Increasing the number of adjusting pads 341 lowers the initial height of the expansion body 33, making it suitable for thicker toilet seats 200. Conversely, decreasing the number of adjusting pads 341 results in a higher initial height of the expansion body 33, suitable for thinner toilet seats 200. Of course, the number of adjusting pads 341 can also be one, two, or more, depending on the specific circumstances.

[0050] The expander 33 is made of rubber, which is durable and has good stability after expansion. Of course, in other embodiments, other materials capable of expansion deformation can also be used.

[0051] Since the distance the screw 31 is lifted is constant, the setting of the fastening nut 32, by adjusting the position of the fastening nut 32 on the screw 31, changes the deformation space of the expansion body 33, thereby achieving different degrees of tightness. If it is necessary to increase the expansion amount of the expansion body 33, the fastening nut 32 is screwed upward, so that the expansion body 33 is subjected to an initial preload. The expansion body 33 has a certain amount of expansion in the initial state (i.e., when it is not lifted); when the screw 31 is lifted, the expansion body 33 continues to be squeezed by the fastening nut 32, thereby achieving a larger amount of expansion. When it is necessary to reduce the expansion amount of the expansion body 33, the fastening nut 32 is screwed downwards. If the expansion body 33 is not compressed in its initial state (i.e., when it is not lifted), or if the expansion body 33 still has a vertical movement stroke, and the expansion body 33 is only compressed by the fastening nut 32 after the screw 31 is lifted, or if the fastening nut 32 begins to compress the fastening nut 32 only after it has risen a certain distance, the expansion amount of the expansion body 33 can be reduced. By adjusting the position of the fastening nut 32, the expansion size of the expansion body 33 can be adjusted to fit various sizes of mounting holes on the toilet seat.

[0052] The support 10 is equipped with a pad 35, and the screw 31 passes through the pad 35. An anti-slip pad 36 is fitted to the bottom of the pad 35, and the adjusting block 34 abuts against the bottom of the pad 35, meaning the adjusting block 34 indirectly abuts against the support 10 through the pad 35. Specifically, the fastener 12 of the support 10 forms an installation cavity 121, and the pad 35 is fitted into this cavity 121, achieving concealed installation. The bottom of the pad 35 has a downwardly protruding boss 352, and the adjusting block 34 abuts against the boss 352. The anti-slip pad 36 has a positioning hole 361, and the boss 352 passes through the positioning hole 361 to achieve precise installation of the anti-slip pad 36. The anti-slip pad 36 is used to contact the toilet seat 200. Of course, in other embodiments, the pad 35 and the anti-slip pad 36 may not be provided. In this case, the adjusting block 34 can directly abut against the support 10.

[0053] Meanwhile, the support 10 is also provided with a limiting mechanism 40. Specifically, two sets of the limiting mechanism 40 are provided, each assembled in the mounting cavity 121 of one of the two fasteners 12. The flip hinge 20 is provided with two hooks 211 that cooperate with the limiting mechanism 40. When the flip hinge 20 is flipped so that the protrusion 23 abuts against the support 10 (i.e., flipped to the first position), as... Figure 11 As shown, the hook 211 engages with the limiting mechanism 40 and is thus secured; this prevents accidental contact with the hinge 20, which could unlock the support assembly and toilet seat 200. The limiting mechanism 40 has a pressing rod 41 for releasing the fixation. When it is necessary to release the fixation between the support assembly and the toilet seat 200, press the pressing rod 41 first to release the limiting mechanism 40 from restricting the hinge 20, after which the hinge 20 can be flipped normally. Of course, the limiting mechanism 40 and the hook 211 can also be configured as a single set, which can still achieve the same limiting effect and can be operated with one hand, making it more convenient.

[0054] Furthermore, the limiting mechanism 40 is assembled in the mounting cavity 121 of the buckle 12 of the support 10. The buckle 12 of the support 10 has an upper opening 122 and a side opening 123 communicating with the mounting cavity 121. The limiting mechanism 40 includes a spring 42 and a pressing rod 41. The pressing rod 41 has a limiting rod 411. The pressing rod 41 is assembled laterally. Specifically, the pad 35 in the mounting cavity 121 has a sliding groove 351, and the pressing rod... The limiting rod 41 is confined within the groove 351 of the pad 35 for lateral assembly; the spring 42 is fitted between the pressing rod 41 and the inner wall of the mounting cavity 121. When the hinge 20 is flipped, its hook 211 is inserted into and locked onto the limiting rod 411 through the upper opening 122. The spring 42 applies a retaining force to the pressing rod 41 to engage with the hook 211. The pressing rod 41 is driven by an external force to disengage the limiting rod 411 from the hook 211. With this configuration, the limiting mechanism 40 has a simple structure, low cost, and is easy to implement.

[0055] Of course, in other embodiments, the structure of the limiting mechanism 40 is not limited to this.

[0056] Example 2

[0057] The quick-release support assembly 100' provided in this embodiment has a structure that is generally the same as the quick-release support assembly 100 provided in Embodiment 1, except that:

[0058] Reference Figures 13 to 18 As shown, the support 10 includes a sleeve 11 and an integral buckle 12 connecting the sleeve 11. In this embodiment, the buckle 12 is an integral flat plate structure connected to the rear side of the sleeve 11. Two sets of screws 31, fastening nuts 32, expansion bodies 33 and adjusting blocks 34 are provided and respectively assembled on the left and right sides of the integral buckle 12. There is one flip hinge 20. The flip hinge 20 abuts against the integral buckle 12 and is connected to two screws 31 through a rotating shaft 24.

[0059] Meanwhile, pads 35 are fitted to the bottom of the left and right sides of the buckle 12, and screws 31 pass through the pads 35. Anti-slip pads 36 are fitted to the bottom of the pads 35. The anti-slip pads 36 are fixedly fastened to the buckle 12 by a snap-fit ​​structure. The anti-slip pads 36 are used to cooperate with the toilet seat, so that the toilet seat (i.e., the seat 51 and the seat ring 52) will not wobble after installation.

[0060] Specifically, the pad 35 extends below the sleeve 11, as shown below. Figure 18 As shown, the buckle 12 is provided with a side slot 125 located below the sleeve 11. The pad 35 is inserted into the side slot 125 for fixation. With this configuration, when the toilet seat is subjected to backward pressure during or after opening, it can be supported by the pad 35 over a wide range, which reduces the amount of tilting of the front end of the support 10.

[0061] The through hole 124 on the buckle 12 for the screw 31 to pass through is larger than the screw 31, so that the screw 31 can move in the through hole 124 of the support 10 to fit toilet seats 200 with different hole spacing. For example, when the distance between the two mounting holes 201 of the toilet seat 200 is small, the two screws 31 can be moved to bring the two screws 31 closer to each other to fit the two mounting holes 201 of the toilet seat 200.

[0062] Meanwhile, the quick-release support assembly of this embodiment does not have the limiting mechanism 40 as in Embodiment 1. In this embodiment, the way to make the flip hinge 20 more stably maintained in a fixed state is as follows: the protrusion 23 is an arc-shaped protrusion, and the flip hinge 20 has an abutting edge 26 connected to the protrusion 23. When the abutting edge 26 of the flip hinge 20 abuts against the buckle 12 of the support 10, the expansion body 33 is compressed and expanded. Figure 15 As shown, the tangent line at the connection position between the protrusion 23 and the abutment edge 26 is defined as the horizontal tangent line a, and the abutment edge 26 is inclined to the horizontal tangent line a and is closer to the pivot 24 than the horizontal tangent line a.

[0063] During installation, external force is applied to the hinge 20, causing it to flip backward. The protrusion 23 of the hinge 20 abuts against the seat 12, lifting the screw 31 and compressing the expansion body 33. The expansion body 33 expands and is fixed to the toilet seat (at this point, it reaches the first position in Embodiment 1). Figure 16 As shown, when the hinge 20 is flipped up to the point where the protrusion 23 is about to disengage from the fastener 12; at this point, the hinge 20 continues to flip up until the abutting edge 26 abuts against the fastener 12 (defined as the third position, as shown). Figure 17 As shown), during the process, screw 31 will move down a certain distance (this downward movement will not affect the fixation of expansion body 33); if it is necessary to switch the flip hinge 20 from the third position to the second position to release the fixed state, an additional force needs to be applied to make screw 31 move up again until it transitions to the first position. In this way, the flip hinge 20 can be more stably maintained in the fixed state (i.e., the third position).

[0064] This embodiment also provides a toilet seat assembly, including the quick-release support assembly 100' provided in this embodiment.

[0065] Although the invention has been specifically shown and described in conjunction with preferred embodiments, those skilled in the art will understand that various changes in form and detail may be made to the invention without departing from the spirit and scope of the invention as defined in the appended claims, all of which shall be within the scope of protection of the invention.
