Detailed Implementation
[0034] The following detailed description of specific embodiments of the present invention is provided with reference to the accompanying drawings. These embodiments are for illustrative purposes only and should not be construed as limiting the scope of the invention.
[0035] Please refer to Figures 1-12. This utility model provides a folding bed, which includes:
[0036] The bed body 1 includes a bed surface 10, bed surface fixing tubes 11 disposed on both sides of the bed surface 10 in the width direction, and a bed surface connector 12 disposed at one end of the bed surface fixing tubes 11.
[0037] Backrest 2, the backrest 2 includes a backrest back 20, backrest fixing tubes 21 disposed on both sides of the backrest back 20, and a backrest connector 22 disposed at one end of the backrest fixing tubes 21, one end of the backrest connector 22 being hinged to the bed surface connector 12;
[0038] The leg frame 3 is fixed to the bed surface fixing tube 11 to support the bed surface. The leg frame includes uprights 32 located on both sides of the fixing tube 11.
[0039] The bracket 3 includes a clamp 4 fixed to the end of the upright 32 on the same side, and a thrust assembly for applying an outward thrust to the clamp. The clamp 4 is provided with a snap-fit groove 42 for snapping the bed surface fixing tube 11 and the backrest fixing tube 21 located on both sides inside it. The thrust assembly is used to apply a thrust to the clamp to tighten the bed surface and the backrest.
[0040] As a specific embodiment of the thrust assembly, the thrust assembly includes a locking structure. At least one end of the upright 32 on the same side is linked to the locking structure, allowing the locking head 4 to rotate along the upright by unlocking the locking structure. When the locking head 4 on the same side rotates until its engagement groove 42 moves away from the engagement groove on the other side, the locking structure locks the locking head 4 at the end of the upright. In the above structure, by opening the locking structure and rotating the locking head 4, a thrust can be applied to it, and the locking structure can then lock the locking head 4 in place.
[0041] Referring to Figure 8, during installation of the folding bed with the above structure, the bed surface fixing tube 11 and backrest fixing rod 21 on the same side are engaged in the engaging groove 42 of the locking head 4, and the bed surface fixing tube 11 and backrest fixing rod 21 on the other side are engaged in the engaging groove of the locking head on the other side. Then, the locking mechanism is opened, and the locking head 4 is rotated to move the engaging grooves 42 between the two locking heads away from each other, thus tightening the bed surface (and backrest). After tightening the bed surface, the locking mechanism is operated to fix the locking heads in the tightened position. This structure simplifies the installation process, eliminating the need for installers to forcefully pull the bed surface and backrest before fixing, thus making the folding bed easy to assemble.
[0042] As a preferred example of a lock structure, referring to Figure 7, the lock structure includes a spring pin 33 protruding from the upright 32 and a locking groove 400 formed on one side of the fixing part 40 that mates with the spring pin 33. One end of the spring pin 33 is elastically biased by an elastic element 100. It also includes an auxiliary handle 43 hinged to the latch 4. The auxiliary handle 43 has a spring pin unlocking boss 430 that mates with the spring pin 33. By rotating the auxiliary handle 43, the spring pin 33 can be pushed out of the locking groove 400. Of course, the lock structure can also be other commonly used structures for locking components, such as a ratchet and pawl locking structure. In this case, the lock structure includes a ring of ratchet teeth on the end of the upright 32 and a pawl elastically biased on the latch 4. After the user opens the pawl, they can freely adjust the rotation position of the latch 4. After closing the pawl, the pawl locks the latch 4 in the rotation position under the action of an elastic restoring force.
[0043] Specifically, the bed surface fixing tube 11 and the bed surface connector 12 are sleeved together, and the backrest fixing tube 21 and the backrest connector 22 are sleeved together. The backrest connector 22 is an angle adjuster. This sleeved connection allows for repeated assembly and disassembly without requiring additional connectors, simplifying installation and reducing manufacturing costs. Using the angle adjuster to rotate the backrest connector upwards causes it to rotate synchronously with the backrest fixing tube connected to one end, creating a comfortable angle between the backrest and the bed surface. This angle can be locked or adjusted using the angle adjuster.
[0044] Specifically, the backrest connector 22 can rotate the backrest fixing tube 21 upwards, so that the backrest back 20 and the bed surface 10 form an angle α. A backrest angle adjustment webbing 100 is connected between the bed surface fixing tubes 11 and the backrest fixing tubes 21 on both sides. When the user pushes the backrest connector upwards, the backrest connector drives the backrest fixing tube connected to one end to rotate synchronously, so that the backrest back and the bed surface form a comfortable angle for leaning against. The backrest angle adjustment webbing is then used to adjust the backrest angle to a suitable position and fix it at the aforementioned angle, allowing the user to comfortably and safely lean against the backrest at a suitable angle.
[0045] As a specific example of the tripod 3, the tripod 3 includes a support leg 31 disposed at the lower end of the upright 32 for reinforcing support, and a leg tube 30 for connecting the support legs 31 on both sides.
[0046] Furthermore, a sleeve 310 is provided on the side of the support leg 31, and the sleeve 310 can be fitted onto the backrest support tube 311. When the user pushes the backrest connector to rotate upward, the backrest connector drives the backrest fixing tube connected to one end to rotate synchronously, so that the backrest back and the bed surface form an angle that can be leaned against. The eccentric rotating head connected to the backrest fixing tube moves synchronously and is suspended in the air, and the leg set below it moves upward and is suspended in the air synchronously. The two support legs of the leg are fixedly provided with sleeves on their sides, and the backrest support tube with its bottom supported on the ground is installed on the sleeves, so that the backrest is fixed at a fixed angle.
[0047] In this embodiment, specifically, the clip head 4 includes a fixing part 40 rotatably disposed on the upright 32 and an eccentric body 41 extending obliquely outward from the fixing part 40, and the clip groove 42 is disposed in the eccentric body 41.
[0048] Referring to Figure 9, when the length of the bed surface 10 is shortened, the number of support legs 31 can be appropriately reduced, allowing the entire folding bed to be used as a chair.
[0049] Referring to Figures 10 and 11, as another embodiment of the thrust assembly: the thrust assembly includes a crossbar 32a connecting two opposing uprights 32, and the end connection between the crossbar 32 and the uprights 32a is an arc transition.
[0050] At this point, the elastic force generated by the plastic deformation of the metal at the connection between the crossbar 32 and the upright 32 forces the upright 32 to tend to return to its original position. Therefore, during installation, the bed surface fixing tube 11 and the backrest fixing rod 21 on the same side are snapped into the snap-fit groove 42 of the snap-fit head 4, and then the upright 32 is pushed forcefully to cause elastic deformation, thereby snapping the bed surface fixing tube 11 and the backrest fixing rod 21 on the other side into the snap-fit groove 42 of the snap-fit head 4 on the corresponding other side. The elastic force of the upright 32 returning to its original position tightens the bed surface and the backrest.
[0051] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
