Description

Technical Field

[0001] This application relates to the technical field of outdoor products, and particularly to a folding bed. Background Art

[0002] A folding bed is a simple bed designed using the joint principle. It can be folded and retracted through various folding methods for convenience and space saving. Due to the advantages of easy use and portability, folding beds usually play a great role during outings or outdoor activities. People can bring a folding bed when camping outdoors or engaging in outdoor sketching, so as to enjoy a comfortable home experience in the smallest space. However, the existing folding beds have cumbersome unfolding and folding steps, requiring locking or unlocking multiple rods in sequence, which is time-consuming and laborious. Moreover, the structural strength of the unfolded folding bed is average and the support stability is poor. When a user turns over on the folding bed, it is easy to shake, resulting in the user falling off the folding bed. Summary of the Invention

[0003] An object of this application is to provide a folding bed with convenient unfolding and folding and good support stability.

[0004] To achieve the above object, the technical solution adopted in this application is: a folding bed, including a support assembly and a bed cloth assembly. The support assembly includes a support crossbar. Connection seats are provided at both ends of the support crossbar. An upper support rod is rotatably connected to the connection seat. A lower leg is rotatably connected to the upper support rod. The bed cloth assembly includes a bed cloth support rod and a support bed cloth. The bed cloth support rod is detachably installed on the upper support rod. The upper support rod and the lower leg can rotate in the same plane to unfold or fold the support bed cloth. A locking member is further provided on the lower leg. The locking member is adapted to be locked and cooperate with the connection seat to limit the rotation and folding of the lower leg, so as to keep the support bed cloth in the unfolded state.

[0005] As a preference, the connection seat includes a first connection portion and a second connection portion. The first connection portion is connected to the support crossbar. An articulated groove is provided in the second connection portion. An articulated rod connected to the upper support rod is provided in the articulated groove. A limiting wall is provided in the articulated groove. When the support assembly is unfolded, the limiting wall is adapted to abut against the upper support rod and the lower leg to limit the maximum unfolded position, and make the support crossbar, the upper support rod and the lower leg form a triangular structure.

[0006] As another preference, the upper support rod includes a hinged end and a mounting end. The hinged end is connected to the hinge rod and rotatably arranged in the hinge groove. The mounting end is provided with a supporting groove, and the bed cloth support rod is detachably clamped in the supporting groove. The top end of the lower leg is rotatably connected to the middle part of the upper support rod, and the lower leg can be operated to drive the upper support rod to rotate and fold or unfold synchronously.

[0007] Further preferably, the lower leg includes a bottom support rod and two side support rods. The top ends of the two side support rods are both hinged to the middle part of the upper support rod. The bottom ends of the two side support rods are respectively fixedly connected to the left and right ends of the bottom support rod. The two side support rods are inclined, so that the whole lower leg is triangular.

[0008] Furthermore, the side support rod includes a connecting section close to the upper support rod and a supporting section far from the upper support rod. The supporting section is inclined relative to the connecting section, so that an included angle is formed between the supporting section and the connecting section, and the degree of the included angle is 155° - 175°.

[0009] Furthermore, the limiting wall extends in the vertical direction. The upper support rod is adapted to abut against the upper end of the limiting wall, so that the upper support rods at both ends of the supporting cross bar are inclined outwards. The supporting cross bar and the upper support rods at both ends of the supporting cross bar form a trapezoidal structure with a wider upper part and a narrower lower part. The connecting section of the lower leg is adapted to abut against the side part of the limiting wall, so that the connecting section extends in the vertical direction. The supporting cross bar and the supporting sections at both ends of the supporting cross bar form a trapezoidal structure with a narrower upper part and a wider lower part.

[0010] Furthermore, the locking member includes a locking push button slidably arranged on the lower leg. The locking push button is provided with a first locking part, and the connecting seat is provided with a second locking part. The locking push button can be operated to slide between a locking position and an unlocking position. When the locking push button is in the locking position, the first locking part abuts and cooperates with the second locking part to limit the rotation and folding of the lower leg.

[0011] Furthermore, the first locking part includes an extension piece and a stop piece. The extension piece is vertically arranged on the back of the locking push button, and the stop piece is arranged at the end of the extension piece. The stop piece has a first locking plane. A receiving cavity is formed on the second locking part, and the second locking part has a second locking plane. The locking push button is adapted to drive the stop piece to slide into the receiving cavity so that the first locking plane and the second locking plane abut and cooperate with each other to limit the rotation and folding of the lower leg.

[0012] Furthermore, the stop member also has a guiding arc surface, and the second locking portion is provided with a guiding inclined surface, and the guiding arc surface is suitable for abutting against the guiding inclined surface to guide the stop member to slide into the accommodating cavity.

[0013] Furthermore, a reset member is provided between the locking push button and the lower leg, and the reset member is suitable for continuously applying a force to the locking push button to move toward the locking position, so that the locking push button can move to the locking position after the external force acting on it is removed.

[0014] Compared with the prior art, the beneficial effects of this application are:

[0015] In the folding bed of the present application, the lower leg can be used as an "operating lever" for folding and unfolding the folding bed and a "support rod" for the folding bed. When unfolding the folding bed, the user only needs to rotate the lower leg, and the lower leg will drive the upper support rod to rotate synchronously so that the two bed cloth support rods move away from each other to support the bed cloth. After the lower leg and the upper support rod are rotated to the maximum unfolded position, the locking piece cooperates with the connecting seat to limit the rotation of the lower leg, thereby preventing the support assembly from folding during the use of the folding bed and causing the supported bed cloth to be retracted; the lower leg is triangular in shape, and the upper support rod and the lower leg in the unfolded state form a trapezoidal structure with the supporting cross bar respectively, thereby improving the structural stability of the folding bed and preventing the folding bed from shaking due to the user turning over.

[0028] It should be noted that the terms "first", "second", etc. in the description and claims of the present application are used to distinguish similar objects, and do not have to be used to describe a specific order or sequence.

[0029] The terms "including" and "having" and any variations thereof in the specification and claims of this application are intended to cover non-exclusive inclusions. For example, a process, method, system, product or apparatus comprising a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to these processes, methods, products or apparatuses.

[0030] like Figures 1-9 As shown, the present application provides a folding bed, which includes: a bed cloth assembly 100 and a plurality of support assemblies, each support assembly being arranged at intervals along the length direction of the bed cloth assembly 100;

[0031] The bed cloth assembly 100 includes two bed cloth support rods 110 arranged in parallel and a bed cloth supporting 120 connected between the two bed cloth support rods 110;

[0032] The support assembly includes a support cross bar 200, and connecting seats 300 are provided at both ends of the support cross bar 200. An upper support rod 400 is rotatably connected to the connecting seat 300, and a lower support leg 500 is rotatably connected to the upper support rod 400. The upper support rod 400 and the lower support leg 500 can be rotated towards or away from the support cross bar 200 in the same plane so that the support assembly can be converted between a folded state and an unfolded state. The bed cloth support rod 110 is detachably mounted on the upper support rod 400, and then when the support assembly is in the folded state, the upper support rod 400 drives the two bed cloth support rods 110 to move towards each other to gather and support the bed cloth 120. When the support assembly is in the unfolded state, the upper support rod 400 drives the two bed cloth support rods 110 to move away from each other to open and support the bed cloth 120. The lower leg 500 is also provided with a locking piece 600 for limiting the rotation of the lower leg 500. The locking piece 600 includes a locking push button 610 and a first locking portion 620 arranged on the locking push button 610. The connecting seat 300 is provided with a second locking portion 330. The first locking portion 620 is suitable for cooperating with the second locking portion 330 to limit the rotation of the lower leg 500, so as to prevent the lower leg 500 from rotating from the unfolded position to the folded position during the use of the folding bed, causing injury to the user sitting or lying on the supporting bed cloth 120.

[0033] like Figure 1 As shown, when the folding bed is unfolded, the upper support rod 400 and the lower support leg 500 are both unfolded away from the supporting cross bar 200, and the upper support rod 400 is tilted outward to drive the two bed cloth support rods 110 to move away from each other to support the bed cloth 120. The bottom end of the lower support leg 500 is in contact with the placement plane, and the first locking portion 620 on the locking push button 610 cooperates with the second locking portion 330 on the connecting seat 300 to keep the folding bed in the unfolded state.

[0034] like Figure 2As shown, when the folding bed is folded, the bed cloth assembly 100 can be installed on the support assembly, and the bed cloth assembly 100 and the support assembly are folded and stored together; the bed cloth assembly 100 can also be separated from the support assembly, and the bed cloth assembly 100 and the support assembly are folded and stored separately. Specifically, when the bed cloth assembly 100 is installed on the support assembly, the upper support rod 400 and the lower support leg 500 are both close to the top of the support cross bar 200, and the upper support rod 400 drives the two bed cloth support rods 110 to move closer to each other to fold the support bed cloth 120; when the bed cloth assembly 100 is separated from the support assembly, the bed cloth assembly 100 and the support assembly are folded and stored separately.

[0035] Furthermore, if Figures 3-5 As shown, the connecting seat 300 includes a first connecting portion 310 and a second connecting portion 320, the second connecting portion 320 is integrally connected to the top of the first connecting portion 310, the end of the supporting cross bar 200 is fixedly connected to the first connecting portion 310, one end of the upper support rod 400 is rotatably connected to the second connecting portion 320, the other end of the upper support rod 400 is detachably connected to the bed cloth support rod 110, the top end of the lower support leg 500 is rotatably connected to the upper support rod 400, and the lower support leg 500 can be operated to drive the upper support rod 400 to rotate and unfold synchronously. In some preferred embodiments, the first connecting portion 310 extends in the horizontal direction, and the second connecting portion 320 extends in the vertical direction, so that the connecting seat 300 as a whole is L-shaped. The second connecting portion 320 specifically includes a limiting wall 322 and two oppositely arranged seat side walls 321. The limiting wall 322 is arranged between the two seat side walls 321, so that the second connecting portion 320 is U-shaped. The two seat side walls 321 and the limiting wall 322 are jointly enclosed to form a hinge groove 323. A hinge rod 324 is arranged in the hinge groove 323. Both ends of the hinge rod 324 are respectively rotatably connected to the two seat side walls 321. The upper support rod 400 is connected to the hinge rod 324 and is rotatably arranged in the hinge groove 323. The limiting wall 322 is suitable for abutting against the upper support rod 400 and the lower support leg 500 to limit the maximum unfolding position of the upper support rod 400 and the lower support leg 500.

[0036] When the upper support rod 400 rotates to the maximum expanded position, the upper support rod 400 abuts against the top end of the limiting wall 322, and the upper support rod 400 is tilted outward. The supporting cross bar 200 and the upper support rods 400 at both ends of the supporting cross bar 200 present a trapezoidal structure that is wide at the top and narrow at the bottom, thereby improving the support stability; when the lower support leg 500 rotates to the maximum expanded position, the lower support leg 500 abuts against the side end of the limiting wall 322, ensuring that the first locking portion 620 on the locking push button 610 is matched and connected with the second locking portion 330 on the connecting seat 300.

[0037] Further, the upper strut 400 includes a hinged end 420 and a mounting end 410. The hinged end 420 is connected to the hinge rod 324 so that the upper strut 400 is rotatably arranged in the hinge groove 323. The mounting end 410 is provided with a support groove 411. The support groove 411 is supported by elastic plastic and is provided with an opening. The bed cloth strut 110 can be detachably clamped in the support groove 411 through the opening. Of course, other detachable connection methods can also be used to connect the mounting end 410 and the bed cloth strut 110. The lower leg 500 includes a bottom strut 510 and two side struts 520. The tops of the two side struts 520 are rotatably connected to the middle of the upper strut 400. The bottoms of the two side struts 520 are integrally connected to the left and right ends of the bottom strut 510 respectively. The two side struts 520 are inclined inward so that the lower leg 500 is triangular. The triangular lower leg 500 has good structural strength and support stability, and can prevent the folding bed from tipping over during use.

[0038] As Figure 6 shown, the side strut 520 of the lower leg 500 further includes a connecting section 521 close to the upper strut 400 and a supporting section 522 far from the upper strut 400. The supporting section 522 is inclined relative to the connecting section 521 so that an included angle is formed between the supporting section 522 and the connecting section 521. The degree of the included angle is 155°-175°. Preferably, the included angle between the supporting section 522 and the connecting section 521 is 170°. The inclined arrangement of the supporting section 522 relative to the connecting section 521 can improve the support stability of the support assembly. Specifically, when the support assembly is in the unfolded state, the lower leg 500 rotates to the maximum unfolded position. The connecting section 521 of the side strut 520 abuts against the side part of the limiting wall 322. The supporting section 522 of the side strut 520 is inclined relative to the placement plane, so that the support cross bar 200 and the lower legs 500 at both ends of the support cross bar 200 form a trapezoidal structure with a narrow upper part and a wide lower part, ensuring the structural strength and support stability of the support assembly and preventing the support assembly from folding and retracting during the use of the folding bed.

[0039] As Figures 3-7As shown, a mounting plate 530 is further provided between the two side support rods 520. The locking push button 610 is slidably disposed on the mounting plate 530. A relief hole 531 is formed in the mounting plate 530. The first locking portion 620 on the back of the locking push button 610 can pass through the relief hole 531 to cooperate with the second locking portion 330 on the connecting seat 300. Specifically, two through slots 532 are formed in the mounting plate 530. The two slots 532 are respectively located on the left and right sides of the relief hole 531. A connecting member 630 that cooperates with the slots 532 is provided on the back of the locking push button 610. The connecting member 630 includes a connecting rod body 631 and a buckle 632. The connecting rod body 631 is vertically disposed on the back of the locking push button 610 and is located within the slot 532. The buckle 632 is disposed at the end of the connecting rod body 631 and abuts against the back end face of the mounting plate 530, so that the locking push button 610 can only slide up and down along the slot 532 between the locked position and the unlocked position, and the locking push button 610 cannot move away from the mounting plate 530 and separate from the mounting plate 530.

[0040] A reset member 640 is further provided between the locking push button 610 and the mounting plate 530. The reset member 640 is adapted to continuously apply a force to move the locking push button 610 towards the locked position, so that the locking push button 610 can be reset to the locked position after the external force is removed. That is to say, the locking push button 610 is normally in the locked position. Only when the user operates the locking push button 610, the locking push button 610 moves from the locked position to the unlocked position. Furthermore, it can be avoided that during the use of the folding bed, the locking push button 610 slides to the unlocked position by itself, resulting in the unlocking of the support assembly. The reset member 640 can be selected from all materials having elastic potential energy. Preferably, the reset member 640 is implemented as a compression spring. The upper end of the compression spring is connected to the mounting plate 530, and the lower end of the compression spring is sleeved on the positioning post of the locking push button 610. When the user operates the locking push button 610 to slide upward to the unlocked position, the compression spring is compressed and deformed. When the user releases the unlocking button, the compression spring returns to its original shape and pushes the locking push button 610 to the locked position.

[0041] The first locking part 620 specifically includes an extension piece 621 and a stop piece 622. The extension piece 621 is vertically arranged on the back of the locking push button 610, and the stop piece 622 is arranged at the end of the extension piece 621. The stop piece 622 has a first locking plane 623 on the side close to the extension piece 621 and a guiding arc surface 624 on the side far from the extension piece 621. The second locking part 330 is arranged on the connecting seat 300. A receiving cavity 331 is formed between the second locking part 330 and the connecting seat 300. The second locking part 330 has a second locking plane 332 on the side close to the receiving cavity 331 and a guiding inclined surface 333 on the side far from the receiving cavity 331. The locking push button 610 is adapted to drive the stop piece 622 to be embedded into the receiving cavity 331 so that the first locking plane 623 and the second locking plane 332 are abutted against each other, thereby restricting the rotation of the lower leg 500.

[0042] During the docking process of the first locking part 620 and the second locking part 330, the guiding arc surface 624 of the stop piece 622 is abutted against the guiding inclined surface 333 of the second locking part 330. The cooperation between the guiding inclined surface 333 and the guiding arc surface 624 can guide the stop piece 622 to slide upward relative to the second locking part 330 to compress the reset piece 640. After the stop piece 622 slides to the unlocking position, the guiding inclined surface 333 is separated from the guiding arc surface 624. At this time, the stop piece 622 is located above the receiving cavity 331, and the reset piece 640 can recover its deformation to push the stop piece 622 into the receiving cavity 331, so that the first locking plane 623 and the second locking plane 332 are abutted against each other and cooperate to restrict the rotation of the lower leg 500. That is to say, during the process of the lower leg 500 being rotated and unfolded by operation, the user does not need to operate the locking push button 610. Just rotate the lower leg 500 to the maximum unfolded position, and the first locking part 620 on the locking push button 610 will automatically lock the lower leg 500 through the cooperation between the guiding arc surface 624 and the guiding inclined surface 333, and keep the folding bed in the unfolded state.

[0043] The above describes the basic principle, main features and advantages of the present application. Those skilled in the art of this industry should understand that the present application is not limited by the above embodiments. What is described in the above embodiments and the specification is only the principle of the present application. Without departing from the spirit and scope of the present application, the present application will have various changes and improvements, and these changes and improvements all fall within the scope of the present application claimed.
