Description

Technical Field

[0001] This utility model relates to the field of living furniture technology, and in particular to a snap-fit ​​frame and bed frame. Background Technology

[0002] In daily life and during sleep, the slippage or wrinkling of bed sheets is a common annoyance affecting the user experience. Specifically, due to friction and inertia generated by human movement, bed sheets are prone to longitudinal or lateral displacement, causing them to wrinkle, slip off, or even detach completely from the mattress. This phenomenon not only affects sleep comfort but also increases the frequency with which users make the sheets at night.

[0003] To solve this problem, users often purchase clips (such as spring clips or retaining clips) to secure the edges of the sheet to the bed frame, slatted bed frame, or under the mattress. While these clips temporarily secure the sheet using mechanical pressure and can limit slippage to some extent, they have the following significant drawbacks:

[0004] The clips are purchased separately by the user and cannot be integrated into the bed frame structure. They need to be stored separately after each sheet washing, and their location is easily forgotten or lost if stored for a long time, making them inconvenient to use.

[0005] Therefore, this utility model aims to improve the existing bed frame, which can solve the problem of bed sheet sliding and shifting, while also avoiding the inconvenience of storage caused by external clips.

[0006] 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

[0007] One objective of this invention is to provide a bed frame with a snap-fit ​​frame, which can solve the problem of bed sheets sliding and shifting, and avoid the inconvenience of storage caused by external clips.

[0008] To achieve the above objectives, on the one hand, this utility model provides a slatted frame with a snap-fit ​​mechanism, comprising:

[0009] The slat frame body has several receiving grooves on its side.

[0010] A plurality of concealed clamping components, each of the concealed clamping components being slidably mounted in one of the receiving slots;

[0011] The concealed clamping assembly has a retracted state in which it slides inward to be housed in the receiving groove; and a state in which it slides outward to the outside of the receiving groove to extend to the edge position for clamping the bed sheet.

[0012] Optionally, the concealed clamping assembly includes:

[0013] The clamp is a U-shaped structure with the opening facing upwards;

[0014] Rotate the clamping plate, the lower end of which extends into the clamping seat and is hinged to the clamping seat;

[0015] The upper part of the rotating clamp has a clamping state in which it rotates to the inside of the clamping seat to clamp and fix the edge of the bed sheet; and an open state in which it rotates to the outside of the clamping seat to release the edge of the bed sheet.

[0016] Optionally, the clamp includes:

[0017] Inner vertical plate;

[0018] An outer vertical plate, which is located outside the inner vertical plate and is disposed opposite to the inner vertical plate;

[0019] The U-shaped connecting part connects the lower ends of the inner vertical plate and the outer vertical plate;

[0020] in,

[0021] The outer vertical plate has a through-panel window in the middle for the rotating clamp to pass through;

[0022] A rotating shaft, hinged to the rotating clamp, is provided on the inner side of the outer vertical plate and below the through-panel window.

[0023] Optionally, the rotating clamp includes:

[0024] A bushing, which is hinged to the outer vertical plate via the rotating shaft;

[0025] A handle plate, the handle plate being located outside the outer vertical plate, and the handle plate being at least partially offset from the through-panel window to restrict the handle plate from passing through the through-panel window;

[0026] The clamping part has one end fixedly connected to the bushing, and the other end extends through the through-plate window to the handle plate;

[0027] When in the clamped state, the clamping part rotates inward to push against the inner side of the inner vertical plate, so as to cooperate with the inner vertical plate to clamp and fix the edge of the bed sheet.

[0028] Optionally, the clamping part is an arc-shaped plate with a convex arch facing the inner vertical plate.

[0029] Optionally, the clamping part is provided with a positioning slot at one end near the handle plate;

[0030] The positioning slot is used to lock the top edge of the through-panel window to maintain the clamped state.

[0031] Optionally, the inner side of the inner vertical plate is provided with a number of anti-slip protrusions arranged in a row from top to bottom.

[0032] Optionally, the outer vertical plate has an arc-shaped structure with a central arch facing the inner vertical plate, such that the distance between the upper ends of the two vertical plates is greater than the distance between the middle parts of the two vertical plates.

[0033] Optionally, the concealed clamping assembly further includes:

[0034] A skateboard, the skateboard being fixed to the bottom of the clamp;

[0035] A fixed guide rail is fixedly installed in the receiving groove, and the fixed guide rail is provided with a horizontal sliding groove for the slide plate to slide in and out of the receiving groove;

[0036] The horizontal slide groove has a sealed end near the accommodating groove to prevent the slide plate from completely detaching from the fixed guide rail when it slides outward; the horizontal slide groove has an open end away from the accommodating groove to allow the slide plate to enter the horizontal slide groove.

[0037] On the other hand, a bed frame is provided, including a bed frame and a snap-fit ​​slatted frame located on top of the bed frame.

[0038] The beneficial effects of this utility model are as follows: It provides a snap-fit ​​slatted frame and bed frame, with multiple receiving slots set on the side of the slatted frame body, and a hidden clamping component slidably installed in each receiving slot. This integrated design makes the hidden clamping component with clamping function an integral part of the snap-fit ​​slatted frame, eliminating the need for users to purchase or manage separate clamps, and completely avoiding the trouble of clamps being easily lost or needing to be searched again after disassembly and cleaning in traditional solutions.

[0039] Specifically, the concealed clamping component has two states: retracted and extended. When not in use, it can be completely stored in the receiving slot to keep the appearance neat. When in use, simply slide the concealed clamping component to expose it on the slatted frame body, and it can be used directly to clamp the edge of the bed sheet. The operation process is simple and quick.

[0040] Multiple clamping components distributed along the slatted frame provide uniform clamping force, effectively suppressing longitudinal or lateral slippage of the sheet during sleep caused by body movement through multi-point fixation. Compared to the localized fixation method of traditional clips, this method keeps the sheet flatter. This structural fixation method is not only more stable and reliable than temporary clips, but also eliminates the need for repeated disassembly and assembly in daily use, improving sleep comfort and simplifying the sheet maintenance process, achieving a balance between functionality and convenience.

[0041] Therefore, the anti-slip bed sheet frame and bed frame provided by this utility model can not only solve the problem of bed sheet sliding and shifting, but also avoid the inconvenience of storage caused by external clips. Attached Figure Description

[0060] The snap-fit ​​frame and bed frame provided by this utility model fundamentally solve the problems of bed sheet sliding and displacement and inconvenient clip storage mentioned in the background art by integrating the clamping function with the bed frame structure through an innovative design.

[0061] The bed frame provided by this utility model includes a bed frame and a snap-fit ​​frame located at the top of the bed frame.

[0062] See Figure 1 The snap-fit ​​slatted frame includes:

[0063] The slat frame body 1 has several receiving grooves 101 on its side.

[0064] A plurality of concealed clamping components 2, each of the concealed clamping components 2 being slidably installed in one of the receiving slots 101;

[0065] The concealed clamping assembly 2 has a retracted state in which it slides inward to be housed in the receiving groove 101; and a state in which it slides outward to the outside of the receiving groove 101 and extends to the edge position for clamping the bed sheet.

[0066] The snap-fit ​​frame provided in this embodiment has multiple receiving slots 101 on the side of the frame body 1. A hidden clamping component 2 is slidably installed in each receiving slot 101. This integrated design makes the hidden clamping component 2 with clamping function an integral part of the snap-fit ​​frame, eliminating the need for users to purchase or manage separate clamps. This completely avoids the trouble of losing clamps or having to search for them again after disassembly and cleaning, which is common in traditional solutions.

[0067] Specifically, the concealed clamping component 2 has two states: retracted and extended. When not in use, it can be completely stored in the receiving slot 101 to keep the appearance neat. When in use, simply slide the concealed clamping component 2 to expose it on the slatted frame body 1, and it can be used to clamp the edge of the bed sheet directly. The operation process is simple and quick.

[0068] Multiple clamping components distributed along the slatted frame provide uniform clamping force, effectively suppressing longitudinal or lateral slippage of the sheet during sleep caused by body movement through multi-point fixation. Compared to the localized fixation method of traditional clips, this method keeps the sheet flatter. This structural fixation method is not only more stable and reliable than temporary clips, but also eliminates the need for repeated disassembly and assembly in daily use, improving sleep comfort and simplifying the sheet maintenance process, achieving a balance between functionality and convenience.

[0069] Therefore, the snap-lock bed frame and bed frame provided by this utility model can not only solve the problem of bed sheet sliding and shifting, but also avoid the inconvenience of storage caused by external clips.

[0070] In this embodiment, the concealed clamping assembly 2 includes a clamping base 201, a rotating clamping plate 202, a sliding plate 203, and a fixed guide rail 204.

[0071] The clamp 201 has an upward-opening U-shaped structure, and the lower end of the rotating clamp 202 extends into the clamp 201 and is hinged to it. The upper part of the rotating clamp 202 has a closed state where it rotates to engage with the clamp 201 to clamp and secure the edge of the bed sheet; and an open state where it rotates to the outside of the clamp 201 to release the edge of the bed sheet.

[0072] Specifically, the clamp 201 includes an inner vertical plate 2011, an outer vertical plate 2012, and a U-shaped connecting portion 2013. The outer vertical plate 2012 is located outside the inner vertical plate 2011 and is disposed opposite to the inner vertical plate 2011; the U-shaped connecting portion 2013 connects the lower ends of the inner vertical plate 2011 and the outer vertical plate 2012.

[0073] in,

[0074] The outer vertical plate 2012 has a through window 2012a in the middle for the rotating clamp 202 to pass through;

[0075] On the inner side of the outer vertical plate 2012 and below the through-panel window 2012a, there is a rotating shaft 2011b that is hinged to the rotating clamp 202.

[0076] Furthermore, combined Figure 1 and Figure 2 The rotating clamp 202 includes a bushing 2021, a handle plate 2022, and a clamping part 2023.

[0077] The bushing 2021 is hinged to the outer vertical plate 2012 via the rotating shaft 2011b. The handle plate 2022 is located outside the outer vertical plate 2012, and the handle plate 2022 is at least partially offset from the through-panel window 2012a to restrict the handle plate 2022 from passing through the through-panel window 2012a. One end of the clamping part 2023 is fixed to the bushing 2021, and the other end extends through the through-panel window 2012a to the handle plate 2022.

[0078] When in the clamped state, the clamping part 2023 rotates inward to push against the inner side of the inner vertical plate 2011, so as to cooperate with the inner vertical plate 2011 to clamp and fix the edge of the bed sheet.

[0079] Optionally, the clamping part 2023 is an arc-shaped plate with a convex arch facing the inner vertical plate 2011, and the clamping part 2023 is provided with a positioning slot 2023a at one end near the handle plate 2022; the positioning slot 2023a is used to clamp the top edge of the through-panel window 2012a to maintain the clamped state.

[0080] Optionally, the inner vertical plate 2011 has a number of anti-slip protrusions 2011a arranged in a row from top to bottom on the inner side, thereby increasing the friction between the bed sheet and the inner vertical plate 2011 and achieving a good anti-loosening effect.

[0081] In this embodiment, the outer vertical plate 2012 has an arc-shaped structure with its center facing the inner vertical plate 2011, making the distance between the upper ends of the two vertical plates greater than the distance between their middle portions. The larger distance between the upper ends of the two vertical plates effectively increases the opening size of the U-shaped clamp 201, facilitating the insertion of the edge of the bed sheet between the two vertical plates. The smaller distance between the middle portions of the two vertical plates allows the clamping part 2023 to approach and push against the inner vertical plate 2011, thereby increasing the clamping force on the bed sheet.

[0082] The slide plate 203 is fixed to the bottom of the clamp 201; the fixed guide rail 204 is fixedly installed in the receiving groove 101, and the fixed guide rail 204 is provided with a horizontal sliding groove 2041 for the slide plate 203 to slide in and out of the receiving groove 101;

[0083] Wherein, the end of the horizontal slide groove 2041 near the opening of the receiving groove 101 is a sealed structure 2042 to prevent the slide plate 203 from completely disengaging from the fixed guide rail 204 when sliding outward; the end of the horizontal slide groove 2041 away from the opening of the receiving groove 101 is an open structure to allow the slide plate 203 to enter the horizontal slide groove 2041.

[0084] Optionally, the guide rail 204 is fixed to the receiving groove 101 with adhesive.

[0085] During assembly, first apply adhesive to the position in the receiving groove 101 where the fixed guide rail 204 is installed. Then, insert the slide plate 203 into the fixed guide rail 204 through the groove end of the horizontal slide groove 2041. Next, insert the entire hidden clamping assembly 2, including the fixed guide rail 204, slide plate 203, and clamp 201, into the receiving groove 101. Finally, wait for the adhesive to cure.

[0086] When the bed sheet needs to be clamped, the hidden clamping component 2 works as follows:

[0087] (1) Initial storage state

[0088] The concealed clamping component 2 is in a clamped state and slides horizontally inward via the slide plate 203, and is stored in the receiving groove 101 of the slat frame body 1. The entire concealed clamping component 2 is completely hidden and stored, with a clean appearance and no protrusions.

[0089] (2) Extension preparation stage

[0090] The user pulls the handle plate 2022 horizontally outward, and the slide plate 203 slides along the horizontal groove 2041 of the fixed guide rail 204 until the slide plate 203 is stopped by the sealing structure 2042 at the end of the groove. At this time, the U-shaped structure of the clamp 201 (inner vertical plate 2011, outer vertical plate 2012 and U-shaped connecting part 2013) is fully exposed and in an opening-up posture.

[0091] (3) Open the rotating clamp 202

[0092] Press down the latch plate 2022, and use the elastic deformation capability of the clamping part 2023 to make the positioning slot 2023a disengage downward from the top edge of the through window 2012a; then, pull the latch plate 2022 outward, so that the clamping part 2023 rotates to the outside of the through window 2012a, and is in an open clamping state, so that the bed sheet can be inserted later.

[0093] (4) Bed sheet insertion operation

[0094] With the help of the curved design of the outer vertical plate 2012, the upper part of the two vertical plates are relatively far apart, making it easy to insert the edge of the bed sheet into the clip 201.

[0095] (5) Clamping action is performed

[0096] Operation of the handle plate 2022: The user rotates the handle plate 2022 inward, causing the handle plate 2022 to drive the clamping part 2023 to rotate inward around the rotation axis 2011b.

[0097] Arc-shaped clamping: The clamping part 2023, which has an arc-shaped structure, arches inward toward the inner vertical plate 2011, pressing the edge of the bed sheet tightly against the inner side of the inner vertical plate 2011.

[0098] Locking mechanism: The clamping part 2023 continues to rotate until the positioning slot 2023a clamps the top edge of the through-plate window 2012a. The clamping state is maintained by mechanical engagement to prevent springback and loosening. This completes the edge clamping operation of the bed sheet and avoids the bed sheet from sliding or shifting.

[0099] (6) The process of releasing the bed sheet

[0100] If the bed sheet needs to be changed later, press down the handle 2022 to disengage the positioning slot 2023a from the top edge of the through-panel window 2012a, then push the handle 2022 outward again to rotate the clamping part 2023 outward until it is completely out of the range of the inner vertical plate 2011 (open clamping state). At this time, the bed sheet can be easily removed. After removing the bed sheet, the hidden clamping component 2 can be pushed back into the receiving slot 101 to reset, or the hidden clamping component 2 can be restored to the closed clamping state first, and then pushed into the receiving slot 101.

[0101] In summary, the snap-fit ​​slatted bed frame and bed frame provided in this embodiment have the following beneficial effects:

[0102] ① Integrated design: The clamping components are combined with the frame body 1 to avoid the problem of losing individual clamps and improve ease of use.

[0103] ② Concealed storage structure: The sliding receiving slot 101 design allows the clamping components to be completely hidden, keeping the bed frame looking neat.

[0104] ③U-shaped clamp 201 + arc-shaped clamping part 2023: The opening is enlarged to facilitate the insertion of the bed sheet, and the arc structure enhances the clamping force and provides better anti-slip effect.

[0105] ④ Mechanical locking mechanism: The positioning slot 2023a engages with the through window 2012a, automatically maintaining the clamped state and preventing the clamp from loosening and failing.

[0106] 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.
