Description

Technical Field

[0001] This utility model belongs to the field of furniture technology, and more specifically it relates to a single bed with adjustable height and length. Background Technology

[0002] Sleep quality and the effective use of living space are core concerns for modern people, especially those living in small urban apartments, student dormitories, studio apartments, or those who need multifunctional spaces. Traditional single beds with fixed sizes and heights are significantly inadequate in meeting diverse and personalized needs.

[0003] Current single beds are generally designed with fixed dimensions, and their height and length cannot be adjusted to meet user needs, which presents many limitations. For example, children's height changes as they grow, requiring frequent replacements of beds with fixed lengths; adults have different height requirements due to varying sleeping habits; and in small apartments, a fixed bed length takes up too much space. Although a few adjustable beds exist on the market, most are electrically adjustable and have complex structures, are expensive, or only allow height adjustment without changing the length, limiting their practicality. Therefore, developing a single bed with a simple structure, convenient manual adjustment, and both height and length adjustment functions is of significant practical importance. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a single bed with adjustable height and length, which has the advantages of enabling manual and flexible adjustment of the bed height and length, improving the convenience of use and space utilization, while ensuring the structural stability and safety after adjustment.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] An adjustable height and length single bed includes a headboard, a telescopic bed frame, height-adjustable support legs, and a length locking assembly; the headboard is fixed to the telescopic bed frame; the height-adjustable support legs are located at the four corners of the bottom of the telescopic bed frame; the length locking assembly is located on the side wall of the telescopic bed frame for fixing the adjusted bed length; the telescopic bed frame includes a main bed frame and a secondary bed frame.

[0007] The advantages of this design are at least as follows: the length can be adjusted by using a telescopic bed frame (main bed frame + auxiliary bed frame), and the height can be adjusted by using height-adjustable support legs, which greatly expands the applicable scenarios of the bed, such as children's growth, users of different heights, and space constraints; the four main functional modules of the bed headboard, telescopic bed frame, support legs, and locking components have a clear structure, which is easy to manufacture, assemble and maintain.

[0008] The present invention is further configured such that: the main bed frame and the auxiliary bed frame are respectively provided with sliding rods and sliding tracks that slide against each other on the side that are close to each other.

[0009] The advantages of this scheme are at least as follows: by setting up sliding rods and tracks, the cooperation between the sliding rods and tracks provides low-friction, high-precision linear guidance, ensuring that the extension and retraction of the main and auxiliary bed frames is smooth and unobstructed; the sliding rod and track structure can effectively distribute the weight of the bed and the human body, ensuring the strength and durability of the extension and retraction parts.

[0010] The present invention is further configured such that: the height-adjustable support leg includes a fixed sleeve, a telescopic inner rod, and a positioning buckle; the fixed sleeve is fixedly connected to the bottom of the telescopic bed frame, and the telescopic inner rod is inserted into the fixed sleeve; the fixed sleeve has a positioning hole on its side, and the telescopic inner rod has multiple sets of corresponding positioning grooves on its side; the positioning buckle can selectively pass through the positioning hole and engage with the corresponding positioning groove to achieve height fixation.

[0011] The advantages of this solution are at least as follows: the combination of positioning holes, positioning slots, and positioning buckles provides an intuitive and reliable height locking method, and users only need to insert and remove the buckles to complete the adjustment and fixation; the design of multiple sets of positioning holes and multiple sets of positioning slots allows for fine-grained height adjustment within a wide range, which can meet different needs.

[0012] The present invention is further configured such that: the positioning buckle is sleeved with a tension spring, and the two ends of the tension spring are respectively fixedly connected to the fixing sleeve and the positioning buckle.

[0013] The advantages of this solution are at least as follows: by setting a tension spring, the positioning buckle automatically remains tightly attached to the positioning groove when not in operation, effectively preventing the buckle from accidentally falling off or being lost, thus improving the convenience and safety of use; the tension spring also provides convenient operation, when the user needs to adjust the support leg, simply pull the buckle, and then release the positioning buckle after adjustment to complete the operation; the design of the tension spring not only makes it convenient to insert and remove the positioning buckle, but also reduces the risk of loosening due to vibration or slight external force.

[0014] The present invention is further configured such that: the bottom of the telescopic inner rod is provided with an anti-slip pad, the anti-slip pad is made of rubber and has a serrated pattern on the bottom.

[0015] The advantages of this solution are at least as follows: by setting anti-slip foot pads, the rubber anti-slip foot pads provide high friction, and the serrated texture further increases the contact resistance and grip with the ground, effectively preventing the bed from sliding or shifting during use, which is especially important on smooth surfaces.

[0016] The present invention is further configured such that: the length locking assembly includes a locking threaded hole and an adjusting handle; the locking threaded hole is disposed on the side of the auxiliary bed frame, and the adjusting handle is threadedly connected to the locking threaded hole via a threaded rod.

[0017] The advantages of this solution are at least as follows: the threaded connection has self-locking properties, and the huge friction generated by tightening the adjustment handle can very firmly lock the main and auxiliary bed frames at the set length, effectively resisting tensile and compressive forces and preventing accidental retraction or extension during sleep or activity; the adjustment handle provides a large lever arm, and users can easily lock or loosen the bed by simply rotating the handle, making the operation labor-saving and convenient.

[0018] The present invention is further configured such that rubber buffer sheets are provided on the opposite end faces of the main bed frame and the auxiliary bed frame.

[0019] The advantages of this solution are at least as follows: by setting up rubber buffers, when the main and auxiliary bed frames are impacted during retraction, the rubber buffers can effectively absorb the impact energy, greatly reducing the noise generated by direct collision of metal parts, improving the user experience and quietness; it can also prevent hands from being pinched during retraction to a certain extent.

[0020] The present invention is further configured such that: the upper and lower surfaces of the slide rod are provided with limiting grooves, and the upper and lower inner walls of the slide rail are provided with limiting blocks that cooperate with the limiting grooves.

[0021] The advantages of this scheme are at least as follows: by setting limit grooves and limit blocks, it is possible to effectively prevent the sub-bed frame from falling off the slide rod due to external force or vibration during the sliding adjustment process; it is also possible to limit the sliding range of the sub-bed frame, so that it can only move within the set range, thereby improving the smoothness and accuracy of the sliding.

[0022] In summary, this utility model has at least the following advantages:

[0023] 1. By setting up sliding rods and tracks, the cooperation between the sliding rods and tracks provides low-friction, high-precision linear guidance, ensuring smooth and unobstructed extension and retraction of the main and auxiliary bed frames; the sliding rod and track structure can effectively distribute the weight of the bed and the human body, ensuring the strength and durability of the extension and retraction parts;

[0024] 2. By incorporating a tension spring, the positioning buckle automatically remains firmly attached to the positioning groove when not in operation, effectively preventing accidental detachment or loss of the buckle and improving ease of use and safety. The tension spring also provides convenient operation; when the user needs to adjust the support leg, simply pull the buckle, and then release the positioning buckle after adjustment to complete the operation. The tension spring design not only makes inserting and removing the positioning buckle convenient but also reduces the risk of loosening due to vibration or slight external force.

[0025] 3. By setting anti-slip foot pads, the rubber anti-slip foot pads provide high friction, and the serrated texture further increases the contact resistance and grip with the ground, effectively preventing the bed from sliding or shifting during use, which is especially important on smooth floors;

[0026] 4. By incorporating rubber buffers, the main and auxiliary bed frames can effectively absorb impact energy during retraction, greatly reducing noise generated by direct collisions between metal parts, improving user experience and quietness; it can also prevent hands from being pinched during retraction to some extent.

[0027] 5. By setting limit grooves and limit blocks, it is possible to effectively prevent the sub-bed frame from falling off the slide rod due to external force or vibration during the sliding adjustment process; it can also limit the sliding range of the sub-bed frame, so that it can only move within the set range, thereby improving the smoothness and accuracy of sliding.

[0034] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description, in conjunction with specific illustrations, further elaborates on this utility model.

[0035] A single bed with adjustable height and length, such as Figure 1 As shown, it includes a headboard 1, a telescopic bed frame 2, height-adjustable support legs 3, and a length-locking assembly 4 (see reference). Figure 2The headboard 1 is fixed to the telescopic bed frame 2; height-adjustable support legs 3 are located at the four corners of the bottom of the telescopic bed frame 2; length-locking components 4 are located on the side walls of the telescopic bed frame 2 to fix the adjusted bed length; the telescopic bed frame 2 includes a main bed frame 21 and a secondary bed frame 22. Length adjustment is achieved through the telescopic bed frame 2 (main bed frame 21 + secondary bed frame 22), and height adjustment is achieved through the height-adjustable support legs 3, greatly expanding the bed's applicable scenarios, such as children's growth, users of different heights, and space constraints; the four main functional modules—headboard 1, telescopic bed frame 2, support legs, and locking components—have a clear structure, facilitating manufacturing, assembly, and maintenance.

[0036] like Figure 2 As shown, the main bed frame 21 and the secondary bed frame 22 are respectively provided with sliding rods 211 and slide rails 221 that slide against each other on the side closest to each other (see reference). Figure 5 By setting up slide rod 211 and slide rail 221, the cooperation between slide rod 211 and slide rail 221 provides low friction and high precision linear guidance, ensuring that the extension and retraction of the main and auxiliary bed frames 22 is smooth and unobstructed; the structure of slide rod 211 and slide rail 221 can effectively distribute the weight of the bed and the human body, ensuring the strength and durability of the extension and retraction parts.

[0037] like Figure 4 As shown, the height-adjustable support leg 3 includes a fixed sleeve 31, a telescopic inner rod 32, and a positioning buckle 33. The fixed sleeve 31 is fixedly connected to the bottom of the telescopic bed frame 2, and the telescopic inner rod 32 is inserted into the fixed sleeve 31. The fixed sleeve 31 has a positioning hole 311 on its side, and the telescopic inner rod 32 has multiple corresponding positioning grooves 321 on its side. The positioning buckle 33 can selectively pass through the positioning hole 311 and engage with the corresponding positioning groove 321 to achieve height fixation. The combination of positioning hole 311, positioning groove 321, and positioning buckle 33 provides an intuitive and reliable height locking method. Users only need to insert and remove the buckle to complete the adjustment and fixation. The design of multiple positioning holes 311 and multiple positioning grooves 321 allows for fine-grained height adjustment within a wide range, which can meet different needs.

[0038] like Figure 4 As shown, a tension spring 5 is sleeved on the positioning buckle 33, with both ends of the tension spring 5 fixedly connected to the fixing sleeve 31 and the positioning buckle 33, respectively. By setting the tension spring 5, the positioning buckle 33 automatically remains tightly against the positioning groove 321 when not in operation, effectively preventing the buckle from accidentally falling off or being lost, thus improving the convenience and safety of use. The tension spring 5 also provides convenient operation; when the user needs to adjust the support leg, they only need to pull the buckle, and after adjustment, they only need to release the positioning buckle 33 to complete the operation. The design of the tension spring 5 not only makes it convenient to insert and remove the positioning buckle 33, but also reduces the risk of loosening due to vibration or slight external force.

[0039] like Figure 2As shown, the bottom of the telescopic inner rod 32 is equipped with an anti-slip pad 6, which is made of rubber and has a serrated pattern on the bottom. By setting the anti-slip pad 6, the rubber anti-slip pad 6 provides high friction, and the serrated pattern further increases the contact resistance and grip with the ground, effectively preventing the bed from sliding or shifting during use, which is especially important on smooth surfaces.

[0040] like Figure 2 As shown, the length locking assembly 4 includes a locking threaded hole 41 and an adjusting handle 42. The locking threaded hole 41 is located on the side of the secondary bed frame 22, and the adjusting handle 42 is threadedly connected to the locking threaded hole 41 via a threaded rod. The threaded connection has self-locking properties. The huge friction generated by tightening the adjusting handle 42 can very firmly lock the main and secondary bed frames 22 at the set length, effectively resisting tensile and compressive forces and preventing accidental retraction or extension during sleep or activity. The adjusting handle 42 provides a large lever arm, and the user can easily lock or loosen the bed by simply rotating the handle, making the operation labor-saving and convenient.

[0041] like Figure 2 As shown, rubber buffer sheets 7 are provided on the opposite end faces of the main bed frame 21 and the auxiliary bed frame 22. By setting the rubber buffer sheets 7, when the main and auxiliary bed frames 22 are impacted during retraction, the rubber buffer sheets 7 can effectively absorb the impact energy, greatly reduce the noise generated by direct collision of metal parts, improve the user experience and quietness; it can also prevent hands from being pinched during retraction to a certain extent.

[0042] like Figure 2 As shown, the slide rod 211 is provided with limit grooves 8 on its upper and lower surfaces, and the slide rail 221 is provided with limit blocks 9 on its upper and lower inner walls that cooperate with the limit grooves 8 (see reference). Figure 5 By setting the limiting groove 8 and the limiting block 9, it is possible to effectively prevent the auxiliary bed frame 22 from falling off the slide rod 211 due to external force or vibration during the sliding adjustment process; it can also limit the sliding range of the auxiliary bed frame 22, so that it can only move within the set range, thereby improving the smoothness and accuracy of the sliding.

[0043] The working process and beneficial effects of this utility model are as follows: When the user needs to adjust the length, place the telescopic bed frame 2 on a flat ground, with the main bed frame 21 and the auxiliary bed frame 22 in their fully retracted state (minimum length). Rotate the adjusting handle 42 of the length locking assembly 4 counterclockwise to disengage the threaded rod from the locking threaded hole 41 on the side wall of the auxiliary bed frame 22, thus releasing the fixation between the main and auxiliary bed frames 22. Pull the auxiliary bed frame 22 so that it extends smoothly along the direction of the auxiliary bed frame 22 via the slide rod 211 and the slide rail 221. Pull the auxiliary bed frame 22 to the desired length. Tighten the adjusting handle 42 clockwise to push the threaded rod against the side wall of the slide rod 211, fixing the telescopic position through friction.

[0044] When the user needs to adjust the height, lift the bed corner so that the height adjustment support leg 3 is temporarily off the ground (user operation required, steps are implicit). Pull out the positioning buckle 33 to disengage it from the positioning groove 321 of the telescopic inner rod 32. Push and pull the telescopic inner rod 32, allowing it to slide up and down within the fixing sleeve 31: raising it pulls out the telescopic inner rod 32, exposing more of the rod. Lowering it pushes the telescopic inner rod 32 in, reducing the exposed portion. Observe the position of the positioning groove 321 on the telescopic inner rod 32 through the positioning hole 311. Align the positioning hole 311 and positioning groove 321 with the target position, and release the positioning buckle 33. The tension spring 5 automatically returns, pushing the positioning buckle 33 through the positioning hole 311 and into the positioning groove 321, completing the locking. Adjust the remaining three support legs to the same height position in sequence to ensure the bed is balanced.

[0045] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the design concept of the present utility model should be included within the protection scope of the present utility model.
