Description

Technical Field

[0001] This utility model relates to the field of bed technology, specifically to a bed with adjustable length and width. Background Technology

[0002] Beds are commonly used in bedrooms, dormitories, hospital wards, hotels, and other similar locations, primarily for daily sleeping. Some beds also track and monitor weight, and their designs are trending towards smart technology. Traditionally, beds were typically made of wood, making them sturdy and practical. Now, stainless steel and other metals are also commonly used, effectively increasing the bed's performance and lifespan.

[0003] A search revealed that patent application number CN202123406253.3 discloses a bed with adjustable length and width. Although the device adjusts the length and width of the bed by setting up support rods, sliding rods, bed boards and side panels, the simple sliding connection between the bed board and the side panels makes the connection part easy to wobble when adjusting the width, resulting in poor overall stability of the bed. In addition, multiple parts need to be operated separately for adjustment, which is cumbersome. Summary of the Invention

[0004] In view of the shortcomings of the prior art, this utility model provides a bed with adjustable length and width, which solves the problems mentioned in the background art.

[0005] The solution to the above-mentioned technical problems provided by this utility model is as follows:

[0006] An adjustable-length and adjustable-width bed includes a headboard and a support board, wherein side beams and a center beam are supported on the headboard and the support board.

[0007] Both the side beam and the middle beam are double-section telescopic structures. A first folding rod and a second folding rod are slidably installed on the side beam and the middle beam. The second folding rods are distributed in a cross pattern, and the middle of two adjacent second folding rods are rotatably connected by a pin.

[0008] The headboard and support plate are respectively supported and installed with a second limiting plate and a first limiting plate by support blocks. The two ends of the side beam are respectively slidably installed on the second limiting plate and the first limiting plate, and the two ends of the middle beam are respectively fixed on the second limiting plate and the first limiting plate.

[0009] Based on the above technical solution, the present invention can be further improved as follows.

[0010] Furthermore, a first sliding groove is provided on the side beam, and sliders are installed at both ends of the second folding rod. The two ends of the second folding rod are slidably installed on the side beam through the sliders and the first sliding groove.

[0011] The beneficial effects of adopting the above-mentioned further solutions are:

[0012] The cooperation between the first slide rail and the slider provides a precise sliding track for the second folding rod, allowing it to move smoothly along a fixed path when adjusting the bed width, avoiding wobbling or jamming. At the same time, this structure restricts the direction of movement of the second folding rod, ensuring its stability during extension and retraction, making bed width adjustment smoother and more reliable, and enhancing the overall durability of the bed structure.

[0013] Furthermore, there are two side beams, which are symmetrically distributed on both sides of the central beam.

[0014] The beneficial effects of adopting the above-mentioned further solutions are:

[0015] The two symmetrically distributed side beams, together with the central beam, form a stable support frame that evenly distributes the pressure on the bed surface, effectively preventing dents or deformations caused by uneven stress. When adjusting the bed's length and width, the symmetrical structure ensures balanced force on both sides, preventing the bed from tilting or shifting during adjustment, thus improving safety and stability during use and providing users with a more comfortable and reliable sleep support environment.

[0016] Furthermore, pads are installed at both ends of the upper layer of the intersecting second folding rods, and the second folding rods are supported on the side beams by the pads.

[0017] The beneficial effects of adopting the above-mentioned further solutions are:

[0018] The pad increases the contact area between the second folding rod and the side beam, making the force on the second folding rod more even when supporting the bed surface, reducing the risk of damage to the side beam due to excessive local pressure. At the same time, the pad acts as a buffer, reducing direct collision and friction between the second folding rod and the side beam when the user turns over or moves, which not only extends the service life of the side beam and the second folding rod, but also reduces noise generated during bed use and improves the quietness of the sleeping environment.

[0019] Furthermore, sliders are also provided at both ends of the side beam, and second grooves are provided on the first and second limiting plates. The side beam is installed on the second limiting plate and the first limiting plate by the cooperation of the sliders and the second grooves.

[0020] The beneficial effects of adopting the above-mentioned further solutions are:

[0021] The second slide groove, in conjunction with the slider, provides a stable guiding structure for the extension and retraction of the side beam. This allows the side beam to move smoothly along a fixed direction when adjusting the bed length, preventing lateral displacement or twisting during the extension and retraction process. This structure enhances the connection stability between the side beam, headboard, and support plate, ensuring that the bed maintains a sturdy overall structure after length adjustment, thus improving the bed's load-bearing capacity and safety.

[0022] Furthermore, a slider is also provided on the pin in the middle of the second folding rod, and a first sliding groove is also provided on the middle beam. The middle part of the second folding rod slides on the middle beam through the cooperation of the slider and the first sliding groove.

[0023] The beneficial effects of adopting the above-mentioned further solutions are:

[0024] The slider in the middle of the second folding rod engages with the first groove on the center beam, further enhancing the stability and flexibility of the second folding rod during width adjustment. When the bed width changes, the middle section of the second folding rod can slide freely on the center beam, ensuring that the cross structure of the second folding rod can unfold or retract smoothly, avoiding any impact on width adjustment due to jamming in the middle. Simultaneously, this structure makes the connection between the second folding rod and the center beam tighter, strengthening the support in the center of the bed surface and improving the overall structural strength and durability of the bed.

[0025] This utility model provides a bed with adjustable length and width. It has the following beneficial effects:

[0026] Both the side beams and the center beam are dual-section telescopic structures, which can flexibly adjust the length and width of the bed according to actual needs, so as to adapt to changes in the size, sleeping habits or room space layout of different users.

[0027] The headboard and support board are supported by support blocks to install the first and second limiting plates respectively. The two ends of the side beams are limited and installed on the limiting plates by sliding blocks and second sliding grooves. The two ends of the middle beam are fixed to the limiting plates. This structure gives the bed good stability and support. At the same time, the second folding rods are distributed in a cross pattern and connected by a pin in the middle. The adjacent folding rods cooperate with each other, which also enhances the stability of the bed surface.

[0028] The second folding rod slides on the first groove of the side beam and the middle beam via a slider. The side beam slides on the second groove of the first and second limiting plates via a slider. This design ensures the flexibility and smoothness of the bed during adjustment, allowing users to easily adjust the size of the bed.

[0029] The upper part of the second folding rods in the cross-distribution system has pads installed at both ends, so that the second folding rods are supported on the side beams by the pads. This design not only ensures the normal sliding of the folding rods, but also provides better support when the bed surface is under pressure, disperses the pressure, and improves comfort.

[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0039] Please see Figures 1 to 4 As shown, the embodiments provided by this utility model are as follows:

[0040] Example 1

[0041] An adjustable length and width bed includes a headboard 1 and a support board 5. Side beams 3 and a center beam 7 are supported on the headboard 1 and the support board 5. There are two side beams 3, which are symmetrically distributed on both sides of the center beam 7. The two symmetrically distributed side beams 3 and the center beam 7 together form a stable support frame, which can evenly distribute the pressure on the bed surface and effectively prevent the bed surface from sinking or deforming due to uneven force. When adjusting the length and width of the bed, the symmetrical structure ensures balanced force on both sides, preventing the bed from tilting or shifting during adjustment, thus improving the safety and stability of the bed during use and providing users with a more comfortable and reliable sleep support environment. Both the side beam 3 and the middle beam 7 are double-section telescopic structures. The first folding rod 2 and the second folding rod 4 are slidably installed on the side beam 3 and the middle beam 7. The side beam 3 has a first sliding groove 301, and the two ends of the second folding rod 4 are equipped with sliders 10. The two ends of the second folding rod 4 are slidably installed on the side beam 3 through the sliders 10 and the first sliding groove 301. The cooperation between the first sliding groove 301 and the sliders 10 provides a precise sliding track for the second folding rod 4, allowing the second folding rod 4 to move smoothly along a fixed path when adjusting the width of the bed, avoiding shaking or jamming. Meanwhile, this structure restricts the movement direction of the second folding rod 4, ensuring its stability during extension and retraction, making the width adjustment of the bed smoother and more reliable, and enhancing the overall durability of the bed structure. The second folding rods 4 are distributed in a crisscross pattern, with adjacent rods 4 connected by a pivot pin. A slider 10 is also provided on the pivot pin in the middle of the second folding rod 4, and a first groove 301 is provided on the center beam 7. The middle section of the second folding rod 4 slides on the center beam 7 through the cooperation of the slider 10 and the first groove 301. The cooperation between the slider 10 in the middle of the second folding rod 4 and the first groove 301 on the center beam 7 further enhances the stability and flexibility of the second folding rod 4 during width adjustment. When the width of the bed changes, the middle section of the second folding rod 4 can slide freely on the center beam 7, ensuring that the crisscross structure of the second folding rod 4 can unfold or retract smoothly, avoiding any impact on the width adjustment effect due to jamming in the middle. Meanwhile, this structure makes the connection between the second folding rod 4 and the central beam 7 tighter, enhancing the support force in the middle of the bed surface and improving the overall structural strength and durability of the bed. The upper ends of the second folding rod 4 in the cross-distributed arrangement are equipped with pads 11, which support the second folding rod 4 on the side beam 3. The pads 11 increase the contact area between the second folding rod 4 and the side beam 3, making the force on the second folding rod 4 more even when supporting the bed surface, reducing the risk of damage to the side beam 3 due to excessive local pressure. At the same time, the pads 11 act as a buffer, reducing direct collisions and friction between the second folding rod 4 and the side beam 3 when the user turns over or moves, extending the service life of the side beam 3 and the second folding rod 4, reducing noise generated during bed use, and improving the quietness of the sleeping environment.

[0042] Example 2

[0043] To further improve the stability and reliability of bed length adjustment and ensure that the bed structure remains stable when dimensions change, for example, such as Figures 1 to 4 As shown, this utility model also includes: a second limiting plate 9 and a first limiting plate 6 are respectively supported and installed on the headboard 1 and the support plate 5 by support blocks 8; the two ends of the side beam 3 are respectively slidably installed on the second limiting plate 9 and the first limiting plate 6; sliders 10 are also provided at both ends of the side beam 3; a second sliding groove 901 is opened on the first limiting plate 6 and the second limiting plate 9; the side beam 3 is limited and installed on the second limiting plate 9 and the first limiting plate 6 by the cooperation of the sliders 10 and the second sliding groove 901. The limiting cooperation between the second sliding groove 901 and the slider 10 provides a stable guiding structure for the extension and retraction of the side beam 3, so that the side beam 3 can move smoothly along a fixed direction when adjusting the length of the bed, avoiding lateral displacement or twisting of the side beam 3 during the extension and retraction process. This structure enhances the connection stability between the side beam 3 and the headboard 1 and the support plate 5, ensuring that the bed maintains a firm overall structure after length adjustment, improving the load-bearing capacity and safety of the bed; the two ends of the middle beam 7 are respectively fixed on the second limiting plate 9 and the first limiting plate 6.

[0044] Working principle:

[0045] When it is necessary to adjust the length or width of the bed, the user should stand to one side of the bed and be ready to make the adjustment.

[0046] Since both the side beam 3 and the middle beam 7 are dual-section telescopic structures, the user holds the two sections of the side beam 3 and the middle beam 7 with both hands respectively, and simultaneously stretches or retracts them outward or inward according to the required length. During this process, the sliders 10 at both ends of the side beam 3 slide within the second grooves 901 of the first limiting plate 6 and the second limiting plate 9, while the two ends of the middle beam 7 are fixed on the first limiting plate 6 and the second limiting plate 9. Through the cooperation of the grooves and the fixed structure, the two ensure smooth extension and retraction, and simultaneously realize the adjustment of the length direction of the bed, ensuring that the length of the middle part of the bed surface and the side supports are always adapted, thus enhancing the overall stability of the bed surface.

[0047] After length adjustment, the bed width can be adjusted. The first folding rod 2 and the second folding rod 4 are slidably mounted on the side beam 3 and the center beam 7. The user pushes the second folding rod 4. The sliders 10 at both ends and the middle of the second folding rod 4 slide within the first grooves 301 of the side beam 3 and the center beam 7. Since adjacent second folding rods 4 are rotatably connected by a pin, during pushing, the second folding rod 4 unfolds or retracts in a cross-structure with the pin as a fulcrum, driving the first folding rod 2 to move, thus changing the bed width. Simultaneously, the pads 11 at both ends of the upper second folding rod 4 slide on the side beam 3, providing support and assisting the sliding.

[0048] Once the length and width of the bed are adjusted to the appropriate size, the friction between the slider 10 and the slide groove allows each component to remain stable in its current position. Without the need for additional fixing devices, the bed can maintain its adjusted shape for the user's use.

[0049] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model.

The scope of this utility model is defined by the appended claims rather than the foregoing description, and thus all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this utility model. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0050] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
