Description

Technical Field

[0001] This invention belongs to the field of infant and toddler products technology, specifically a bread-shaped bed. Background Technology

[0002] A crib provides a comfortable sleeping environment for your baby, ensuring good sleep quality and promoting healthy physical development. Secondly, a crib gives your baby their own space, fostering independence from a young age. Thirdly, a crib prevents adults from rolling over onto your baby or accidentally covering their head with a blanket, and it also effectively prevents falls.

[0003] For example, patent number CN217792246U discloses a baby folding bed that solves the problem in existing technologies where the folding structure simultaneously possesses folding and support functions, which may affect the stability of the baby folding bed. This baby folding bed includes: a bed frame, comprising a first branch and a second branch, with a first accommodating space between them; and a first folding section located between the first and second branches, configured such that the tension generated when the first folding section is folded causes the first and second branches to move closer together along a first direction, and the thrust generated when the first folding section is unfolded pushes the first and second branches away from each other along the first direction; and a load-bearing section located within the first accommodating space, including a load-bearing surface, configured to be supported by the bed frame with its load-bearing surface facing the object being supported. The folding function of the folding section and the support function of the bed frame in the baby folding bed provided by this invention do not interfere with each other, resulting in good stability and easy storage of the baby folding bed.

[0004] However, due to structural limitations, the folding parts of this baby folding bed are folded separately and do not affect each other. Therefore, folding and unfolding require separate operation of multiple parts, and the bed frame will not unfold synchronously. Consumers need to pull the folding connecting rod to open it, which is relatively troublesome and time-consuming and not very convenient. At the same time, the armrests fold and open asynchronously. Summary of the Invention

[0005] The purpose of this invention is to solve the problems mentioned above, such as the need to operate multiple parts separately when folding and unfolding, the bed frame not unfolding synchronously, requiring the consumer to pull the folding connecting rod again to open it, which is troublesome, time-consuming and inconvenient. At the same time, the armrests fold and open asynchronously. This invention provides a bread-shaped bed.

[0006] The technical solution adopted in this invention is as follows: A bread-shaped bed, wherein an inner frame is fixedly connected to one side of the folding upright, a handrail roller is rotatably connected to one side edge of the inner frame, a rod sleeve is fixedly connected to one side of the handrail roller, a first handrail is fixedly connected inside the rod sleeve, a second handrail is fixedly installed on the opposite side of the first handrail, a rod head is fixedly installed on one side of the first handrail, a rotating iron plate is fixedly installed on one side of the rod head, an elongated slot is opened on the side of the rotating iron plate, one side of the rotating iron plate is rotatably inserted into a connecting rod, one side of the connecting rod is slidably connected to an inner iron block, a locking button is slidably connected to one side of the inner iron block, and a square tube is fixedly installed on the upper surface edge of the inner iron block.

[0007] By adopting the above technical solution, when the first and second armrests are folded, the rotating iron plate squeezes the connecting rod, causing the connecting rod to move downwards. This allows the position change on one side of the first and second armrests to drive the change on the other side, thus enabling the first and second armrests to open and close simultaneously. This makes the folding and closing operation of the bread bed more convenient. When unfolded, the square tube can be inserted into the long slot, making the unfolded bread bed more stable in the unfolded and locked state. By pushing the locking button upwards, the engagement between the square tube and the long slot can be opened, thereby achieving the purpose of unlocking. This makes the bread bed more stable and also makes the storage of the bread bed more convenient.

[0008] In a preferred embodiment, a supporting iron plate is fixedly connected to one side edge of the folding column. A slot is formed on the upper surface of the supporting iron plate. A foot is rotatably inserted into one side of the slot. One side edge of the foot is fixedly connected to a gear component. The side of the gear component rotatably contacts a rack component. A slot is formed on the lower surface of the rack component. A base is fixedly installed inside the slot.

[0009] By adopting the above technical solution, the supporting iron plate serves as a stable base, providing stability and a pivot point for rotation for the foot. The gear component fixes the other side of the foot, and the toothed side of the foot contacts the ruler-shaped side of the rack component during movement. This allows the base to rotate and drive the rack component to rise and fall. When the rack component rises and falls, it drives the other foot to rotate, allowing both feet to open and close simultaneously. This, in turn, drives the folding column to open and close simultaneously, making the bread bed easier to unfold and store.

[0010] In a preferred embodiment, a cover is fixedly installed on the upper surface of the folding column, and a decorative cover pin is fixedly installed on the lower edge of the cover. The side of the decorative cover pin is slidably inserted into a decorative cover groove, which is formed in the decorative cover. A sliding groove is formed on one side of the folding column, and a decorative cover is slidably connected to the inside of the sliding groove. A hook groove is formed on one side of the decorative cover, and a spring hook part is fixedly installed on the inside of the sliding groove.

[0011] By adopting the above technical solution, the decorative cover is slidably inserted into the groove. A hook groove is provided on one side of the decorative cover to fix the spring hook part. When the decorative cover is pressed, the spring hook part will swing left and right under the action of the hook groove on the back of the decorative cover. Then the hook will catch the spring hook part. If the decorative cover is pressed again, the spring hook part will continue to swing to the right to get out of the control of the hook. Then the spring hook will pop out. Thus, the opening and closing of the decorative cover can be changed by pressing the decorative cover. This makes it convenient for users to choose whether to let the decorative cover nail be locked into the groove of the decorative cover for fixation. This enhances the adjustability of the product and makes the product appearance neat and without protrusions.

[0012] In a preferred embodiment, a support bone soft layer is fixedly installed on one side of the inner frame, and a support bone soft layer is fixedly installed on one side of the folding column.

[0013] By adopting the above technical solution, the scaffold bone soft lining can not only protect the inner frame and other components, but its softness also makes the user feel better when using and opening / closing the bread bed.

[0014] In a preferred embodiment, a supporting iron plate is fixedly connected to one edge of the folding column, and an auxiliary rod is rotatably connected to one side of the supporting iron plate.

[0015] By adopting the above technical solution, the supporting iron sheet provides support for the construction of the components under the bread bed, and the auxiliary rod is an auxiliary rod under the bread bed, which can make the structure of the bread bed more stable.

[0016] In a preferred embodiment, a tension spring is fixedly installed on one side of the auxiliary rod, and a tension spring is fixedly installed on the opposite side of the tension spring.

[0017] By adopting the above technical solution, the tension spring is fixedly installed on the auxiliary rod. When the bread bed is unfolded, the tension spring can be kept in a state of tension by changing the contact point of the tension spring. This will give the bed a pre-tightening force when it is open, making it difficult for the bed to close.

[0018] In a preferred embodiment, an outer protective plate is fixedly connected to one side of the inner iron block, and a slot is formed on one side of the outer protective plate.

[0019] By adopting the above technical solution, the outer protective plate makes the structure of the closing component more stable, while preventing the internal components from being exposed and causing injury to the user. The slots on the outer protective plate facilitate the user's operation of the locking button.

[0020] In a preferred embodiment, one side of the auxiliary rod is rotatably connected to a limiting plate, and the upper surface of the limiting plate is fixedly connected to an outer support ring.

[0021] By adopting the above technical solution, the limiting plate can stabilize the movement trajectory of the base during movement, and the outer support iron ring on the limiting plate can provide protection and structural stability for the interior of the synchronous closing structure.

[0022] In a preferred embodiment, a transition block is fixedly installed on the lower surface of the supporting iron plate, and an axle is rotatably inserted into the lower surface of the transition block, with a caster wheel rotatably inserted into the side of the axle.

[0023] By adopting the above technical solution, the adapter block provides stable support for the installation of the casters, and the axle allows the casters to freely adjust their rolling direction when rolling, making the bread bed more flexible when moving.

[0024] In a preferred embodiment, the omnidirectional wheel is slidably connected to a rotation-damping brake.

[0025] By adopting the above technical solution, the anti-roll brake component can generate a large friction force when in contact with the ground, thereby preventing the van from rolling. Without sacrificing the van's maneuverability and flexibility, the van will not move when facing uneven ground, greatly improving the van's safety.

[0026] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0027] In this invention, when the first and second armrests are folded, the rotating iron plate presses against the connecting rod, causing the connecting rod to move downwards. This allows the positional change of one side of the first and second armrests to drive the change of the other side, enabling the first and second armrests to open and close simultaneously, making the folding and closing operation of the bread bed more convenient. When unfolded, the square tube can be inserted into the long slot, making the unfolded bread bed more stable in the unfolded locked state. By pushing the locking button upwards, the engagement between the square tube and the long slot can be released, thereby achieving the purpose of unlocking the bread bed. This makes the bread bed more stable and easier to store. The supporting iron plate serves as a stable base, providing stability and a pivot point for rotation for the feet. The gear component fixes the other side of the feet, and the toothed side of the feet contacts the ruler-shaped side of the rack component during movement, allowing the feet to drive the gear during rotation. The rack and pinion mechanism allows the other foot to rotate during lifting, enabling simultaneous opening and closing of both feet. This, in turn, opens and closes the folding column, making the bread bed easier to unfold and store. The decorative cover slides into a groove, with a hook groove on one side to secure the spring hook. When the cover is pressed, the spring hook swings left and right under the hook groove on the back. The hook then catches the spring hook. Continuing to press the cover causes the spring hook to swing to the right, disengaging from the hook. The spring hook then pops out, allowing the user to choose whether to lock the cover into the groove for secure fastening. This enhances the product's adjustability and maintains a clean, protrusion-free appearance. Attached Figure Description

[0047] The implementation principle of a bread bed embodiment of the present invention is as follows: An inner frame 20 is fixedly connected to one side of the folding upright 1; an armrest roller 6 is rotatably connected to one side edge of the inner frame 20; a rod sleeve is fixedly connected to one side of the armrest roller 6; a first armrest 2 is fixedly connected inside the rod sleeve; a second armrest 3 is fixedly installed on the opposite side of the first armrest 2; mounting holes are provided on one side edge of the first armrest 2 and the second armrest 3; a rod head is fixedly installed on one side of the first armrest 2; a rotating iron plate 4 is fixedly installed on one side of the rod head; a non-standard arm bar is threadedly connected to one side of the rotating iron plate; and the side of the rotating iron plate 4 is... A long slot is provided. One side of the rotating iron plate 4 is rotatably inserted into the connecting rod, and one side of the connecting rod is slidably connected to the inner iron block 23. A locking button 5 is slidably connected to one side of the inner iron block 23. A slot is opened on one edge of the inner iron block, and a buffer spring is fixedly installed on the lower surface of the slot. A square tube is fixedly installed on the upper edge of the inner iron block 23. When the first handrail 2 or the second handrail 3 is closed, the first handrail 2 or the second handrail 3 will move downward. Due to the pressure of the rotating iron plate 4 on the connecting rod, the connecting rod moves downward. The downward movement of the connecting rod will cause the handrail on the opposite side to be subjected to the force of the connecting rod. The movement of the first armrest 2 and the second armrest 3 together allows the positional change of one side to drive the movement of the other side, enabling the first armrest 2 and the second armrest 3 to open and close simultaneously. This makes the folding and closing operation of the bread bed more convenient. The irregularly shaped armrests restrict and stabilize the movement of the armrests when the first armrest 2 and the second armrest 3 move, maintaining the stability of the armrest structure and preventing misalignment. The buffer springs absorb the force of the armrest movement, making the movement smoother and reducing the impact and wear on the folding components caused by the force of the movement. This ensures that the bread bed opens smoothly when unfolded. As the tube moves upward, the square tube shifts upward and engages with the long slot, locking the first armrest 2 and the second armrest 3. This makes the unfolded bread bed more stable in its unfolded and locked state. By pushing the locking button 5 upward, which is fixedly connected to the unlocking bar, the unlocking bar moves upward through the locking button, thus unlocking the square tube and the long slot. This achieves automatic locking and one-button unlocking of the first armrest 2 and the second armrest 3, making the bread bed more stable and easier to store.

[0048] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
