Description

Technical Field

[0001] This utility model relates to the field of living furniture technology, and in particular to an inflatable, sew-filled bed frame. Background Technology

[0002] Existing bed frames include:

[0003] A bed frame, the bed frame surrounding and forming an inner cavity;

[0004] A slatted frame, located within the inner cavity of the frame, divides the inner cavity into a bed frame base cavity and a mattress mounting cavity.

[0005] To facilitate the placement of the mattress into the mattress mounting cavity, the size of the mattress mounting cavity is usually slightly larger than the size of the mattress. This results in a large gap (hereinafter referred to as "bed gap") between the mattress and the cavity wall after the mattress is placed on the slatted frame. This not only affects the aesthetics but also makes it easy for items to fall out.

[0006] However, if the size of the mattress installation cavity is designed to be exactly the same as the size of the mattress, the mattress installation will be very difficult, and the cavity wall will directly scratch the side of the mattress, damaging it.

[0007] Therefore, existing bed frames need to be improved so that they can avoid excessive gaps between the mattress and the bed frame that affect aesthetics, and also protect the sides of the mattress from wear and tear.

[0008] The information disclosed in this background section is included only to enhance the understanding of the context of this disclosure, and therefore may contain information that does not constitute prior art known to those skilled in the art. Utility Model Content

[0009] One objective of this invention is to provide an inflatable, gap-filled bed frame that can both prevent the bed frame from having excessively large gaps between the mattress and the bed frame, thus avoiding affecting the aesthetics, and protect the sides of the mattress from wear and tear.

[0010] To achieve the above objectives, this utility model provides an inflatable, gap-filling bed frame, comprising:

[0011] A bed frame that surrounds a frame cavity for placing a mattress;

[0012] A joint filler assembly, wherein the joint filler assembly is installed on the cavity wall of the inner cavity of the frame;

[0013] The filling component has an inflated state in which it expands after being inflated to fill the gap between the mattress and the bed frame; and a deflated state in which it contracts after being deflated to expose the gap.

[0014] Optionally, the caulking assembly includes a support substrate mounted on the cavity wall and a caulking airbag fixed to the side of the support substrate away from the cavity wall.

[0015] Optionally, the caulking assembly further includes an inflation / deflation pump connected to the caulking airbag and a control panel communicatively connected to the inflation / deflation pump.

[0016] Optionally, it also includes a slatted frame installed inside the frame cavity, wherein the installation height of the slatted frame is lower than that of the caulking assembly.

[0017] Optionally, the caulking assembly is snap-fitted and fixed to the cavity wall.

[0018] Optionally, the cavity wall is provided with a plurality of T-shaped pins protruding toward the inner cavity of the frame;

[0019] The caulking assembly has a pin slot on the surface facing the cavity wall for the head of the T-shaped pin to be engaged.

[0020] Optionally, the pin slot is a continuous groove that extends along the length of the caulking assembly;

[0021] Alternatively, each of the T-shaped pins may be provided with a corresponding pin slot, and the pin slots may be arranged at intervals along the length of the sealant assembly.

[0022] Optionally, the slot through which the head of the T-shaped pin passes in the pin slot is a tapered guide structure whose size gradually decreases toward the pin slot.

[0023] Optionally, the caulking assembly is rotatably connected to any top edge of the inner cavity of the frame about a horizontal pivot.

[0024] The seam filling assembly has a straight state in which it can rotate to be horizontally positioned within the frame cavity to fill the seam between the mattress and the bed frame; and an upturned state in which it can rotate to the outside of the frame cavity to allow the slatted frame to enter and exit the frame cavity.

[0025] Optionally, the top surface of the bed frame is recessed from top to bottom to form a positioning groove for the caulking assembly to slide into;

[0026] The seam filling component has an insertion state in which it is inserted into the positioning groove from top to bottom to fill the seam between the mattress and the bed frame; and an extraction state in which it slides from bottom to top to disengage from the positioning groove so that the slatted frame can enter and exit the inner cavity of the frame.

[0027] The beneficial effect of this utility model is that it provides an inflatable, sew-filled bed frame:

[0028] During mattress installation, the filling components can remain deflated, causing them to shrink in volume, thus providing sufficient operating space for the mattress and avoiding installation difficulties caused by an insufficiently small mattress installation cavity.

[0029] Once the mattress is in place, the filling component inflates and automatically fills the gap between the mattress and the bed frame. This eliminates the aesthetic problem caused by excessively large gaps and prevents small items from falling through. Furthermore, the inflated filling component wraps around the sides of the mattress with a flexible material, using elastic cushioning to avoid scratches and damage caused by traditional hard cavity walls. Even if the mattress shifts slightly during use, the air cushion structure can absorb friction through deformation, thus providing long-term protection for the mattress.

[0030] Therefore, the inflatable seam-filling bed frame provided by this utility model can not only avoid the bed frame from having too large a gap between the mattress and the bed frame, which would affect the aesthetics, but also protect the sides of the mattress from wear and tear.

[0049] The inflatable grout bed frame provided by this utility model cleverly solves the contradictions that exist in the installation and use of mattresses in traditional bed frames by adopting an inflatable and deflated grout component.

[0050] See Figure 1 The inflatable sprue bed frame provided by this utility model includes:

[0051] Bed frame 1, the bed frame 1 surrounds a frame cavity 101 for placing a mattress;

[0052] The joint filling component 3 is installed on the cavity wall of the inner cavity 101 of the frame;

[0053] The filling component 3 has an inflated state that expands after inflation to fill the gap between the mattress and the bed frame 1; and a deflated state that contracts after deflation to expose the gap.

[0054] During mattress installation, the filling component 3 can remain deflated, causing it to shrink in volume, thus providing sufficient operating space for the mattress and avoiding installation difficulties caused by an insufficiently small mattress installation cavity.

[0055] Once the mattress is in place, the seam filling component 3 inflates and automatically fills the gap between the mattress and the bed frame 1. This eliminates the aesthetic problem caused by excessively large gaps and prevents small items from falling through. Furthermore, the inflated seam filling component 3 wraps around the sides of the mattress with a flexible material, using elastic cushioning to avoid scratches and damage caused by traditional hard cavity walls. Even if the mattress shifts slightly during use, the air cushion structure can absorb friction through deformation, thus providing long-term protection for the mattress.

[0056] This design, through the dynamic adjustment capability of the inflatable structure, ensures both ease of installation and a seamless fit and protective effect during use, fundamentally resolving the contradiction between ease of installation and safety in the size design of traditional bed frames.

[0057] Therefore, the inflatable seam-filling bed frame provided by this utility model can not only avoid the bed frame from having too large a gap between the mattress and the bed frame, which would affect the aesthetics, but also protect the sides of the mattress from wear and tear.

[0058] In this embodiment, see Figure 2 The caulking assembly 3 includes a support substrate 301 (e.g., a rigid plastic or metal plate) mounted on the cavity wall, and a caulking airbag 302 fixed to the side of the support substrate 301 away from the cavity wall.

[0059] Furthermore, the caulking assembly 3 also includes an inflation / deflation pump 303 connected to the caulking airbag 302, and a control panel 304 communicatively connected to the inflation / deflation pump 303.

[0060] By setting the support substrate 301 as a support frame, the filling component 3 can maintain a stable structural shape when inflated, avoiding the torsional deformation that may occur with a simple airbag structure. At the same time, the fixed connection between the support substrate 301 and the cavity wall provides a reliable installation base for the filling airbag 302, allowing the inflated airbag to apply force evenly to the sides of the mattress. This rigid-flexible structure not only ensures the tightness of the filling, but also disperses the local pressure of the mattress on the airbag through the support substrate 301.

[0061] The integrated air pump 303 and control panel 304 enable one-button operation, allowing users to quickly switch between caulking states according to usage scenarios. Optionally, the bed frame 1 has a headboard near the headboard, and the control panel 304 is fixed to the side of the headboard. This design is ergonomic, avoiding damage to the overall aesthetics of the bed and facilitating operation while standing without bending over.

[0062] The inflatable, seam-filled bed frame also includes a slatted frame 2 installed within the inner cavity 101 of the frame. The slatted frame 2 is installed at a lower height than the seam-filling assembly 3, ensuring that the seam-filling assembly 3 can contact the side of the mattress. This height difference design ensures that the seam-filling assembly 3 always maintains contact with the side of the mattress. Regardless of any slight movement of the mattress on the slatted frame 2, the seam-filling assembly 3 can dynamically adapt to its positional changes and provide a seal. This combination of "low-mounted" slatted frame 2 and "high-contact" seam-filling assembly 3 fundamentally solves the problem of seam-filling failure caused by height misalignment.

[0063] See Figure 3 In this embodiment, the caulking assembly 3 is snap-fitted to the cavity wall. This snap-fitting of the caulking assembly 3 facilitates the insertion or removal of the slatted frame 2 after disassembly.

[0064] Optionally, the cavity wall is provided with a plurality of T-shaped pins 102 protruding toward the inner cavity 101 of the frame; the surface of the caulking assembly 3 facing the cavity wall is provided with pin slots 3011 for the heads of the T-shaped pins 102 to be engaged.

[0065] In this embodiment, the pin slot 3011 is a continuous slot that can engage with the T-shaped pin 102 at multiple positions, thereby reducing the difficulty of aligning the T-shaped pin 102 and the pin slot 3011 and improving the assembly and disassembly efficiency of the caulking assembly 3.

[0066] Of course, in some other embodiments, each of the T-shaped pins 102 may be provided with a corresponding pin slot 3011, and the pin slots 3011 may be arranged at intervals along the length of the caulking assembly 3.

[0067] In this embodiment, the slot of the pin groove 3011 through which the head of the T-shaped pin 102 passes is a tapered guide structure 3012 whose size gradually decreases toward the pin groove 3011. At the slot of the pin groove 3011, the structural strength is reduced due to the opening design, allowing for some deformation. Therefore, when the head of the T-shaped pin 102 presses against the slot of the pin groove 3011 from the outside in, the size of the slot of the pin groove 3011 will appropriately expand, allowing the head of the T-shaped pin 102 to pass through. After the head of the T-shaped pin 102 passes through the slot of the pin groove 3011, the slot of the pin groove 3011 returns to its original deformed position, thus locking the head of the T-shaped pin 102. Furthermore, the tapered guide structure 3012 achieves a "push-in self-locking" installation effect, requiring only unidirectional force to engage the T-shaped pin 102 during installation. At the same time, the inclined guide eliminates the need for precise alignment during installation, significantly improving assembly efficiency.

[0068] It should be noted that snap-fit ​​fixing is only one of many ways to detachably connect the caulking assembly 3 to the bed frame 1. In some other embodiments, the caulking assembly 3 and the bed frame 1 can also be connected in the following ways:

[0069] (1) Hinged

[0070] See Figure 4 The filling component 3 is rotatably connected to either top edge of the inner cavity 101 of the frame about a horizontal pivot; the filling component 3 has a flat state in which it is rotated to be horizontally located inside the inner cavity 101 to fill the bed seam between the mattress and the bed frame 1; and an upward state in which it is rotated to the outside of the inner cavity 101 to allow the slatted frame 2 to enter and exit the inner cavity 101.

[0071] The grouting component 3 is flipped via a horizontal pivot, creating a unique "working state switching" mechanism:

[0072] ① When flipped up, the filling component 3 rotates outward to the outside of the bed frame 1, completely emptying the vertical projection space of the entire inner cavity 101 of the frame, providing an unobstructed passage for the installation / removal of the slatted frame 2. This design breaks through the process limitation of traditional bed frames, which require the frame to be installed first and then the slatted frame 2 to be placed, allowing the installation of large-volume components such as the "integral slatted frame 2".

[0073] ② In the straight position, the rotated and repositioned joint filler component 3 naturally forms a vertical cover over the slat frame 2, automatically meeting the positioning requirement that "the installation height is lower than the joint filler component 3". This dynamic adjustment method is more precise than fixed installation and can compensate for positional errors during the installation of the slat frame 2.

[0074] (2) Top and bottom plug-in connection

[0075] See Figure 5 The top surface of the bed frame 1 is recessed from top to bottom to form a positioning groove 103 for the slidable insertion of the filling component 3; the filling component 3 has an insertion state in which it is inserted into the positioning groove 103 from top to bottom to fill the bed gap between the mattress and the bed frame 1; and an extraction state in which it slides from bottom to top to disengage from the positioning groove 103 so that the slatted frame 2 can enter and exit the inner cavity 101 of the frame.

[0076] A novel "drawer-type" caulking system is established through the cooperation of vertical sliding and positioning groove 103:

[0077] ① When in the withdrawn state, the caulking component 3 is completely withdrawn from the inner cavity 101 of the frame in the vertical direction. Its effect is equivalent to temporarily removing the side wall of the bed frame 1, completely emptying the vertical projection space of the entire inner cavity 101 of the frame, providing an unobstructed passage for the installation / disassembly of the frame frame 2. However, compared with the rotating structure, the linear plug-in structure is more suitable for installation environments with insufficient height space.

[0078] ② When inserted, the depth limit of the positioning groove 103 ensures that the lower end of the caulking assembly 3 is always above the mounting plane of the slat frame 2, thus mechanically controlling the height difference.

[0079] In summary, the inflatable sprue bed frame provided in this embodiment has the following advantages:

[0080] ① Dynamic gap filling adjustment: By switching between inflation and deflation states, it can both preserve the installation space of the mattress and achieve seamless filling during use, thus resolving the contradiction between the convenience of installation and the safety of use of traditional bed frames.

[0081] ② Rigid-flexible composite structure: The design of the support base material 301 and the filling airbag 302 ensures stability while avoiding wear and tear on the sides of the mattress and extending the mattress's lifespan.

[0082] ③ Modular snap-fit ​​design: The T-shaped pin 102 and the pin slot 3011 work together to achieve quick assembly and disassembly, which is convenient for the maintenance or replacement of the frame 2.

[0083] ④ Flip-type space release: The horizontal pivot structure allows the grouting component 3 to flip outward, completely emptying the inner cavity 101 of the frame, and supporting the overall installation of the large-volume slatted frame 2.

[0084] ⑤ Sliding space release: The mechanical limit of the vertical sliding insertion into the positioning groove 103 accurately maintains the height difference between the caulking component 3 and the slat frame 2, adapting to low space environments.

[0085] Finally, it should be noted that although the above embodiments have been described in the text and drawings of this application, this should not limit the scope of patent protection of this application. Any technical solutions that are based on the essential concept of this application and utilize the content described in the text and drawings of this application, resulting in equivalent structural or procedural substitutions or modifications, as well as the direct or indirect application of the technical solutions of the above embodiments to other related technical fields, are all included within the scope of patent protection of this application.
