Description
Technical Field
[0001] This utility model relates to the field of folding bed technology, specifically to a box-type folding bed. Background Technology
[0002] A folding bed is a type of bed that can be changed in its usage configuration. Currently, folding beds on the market mainly include soft folding beds and hard folding beds. Existing soft folding beds lack storage functions, leaving no place to store bedding and other accessories, resulting in a cluttered environment. Furthermore, while soft folding beds are suitable for short rests, sleeping on them for extended periods can be tiring and prevent proper rest. Ordinary hard folding beds, on the other hand, are large and bulky, making them inconvenient to move and store.
[0003] In view of the above problems, we have developed a box-type folding bed that can use a hard bed surface and combines sitting, lying down and storage functions. When folded, the bed board can be placed inside the box, and the box can hold items, which helps to keep the environment tidy and improve the quality of rest. Utility Model Content
[0004] The purpose of this invention is to provide a box-type folding bed that solves the problem that existing folding beds cannot simultaneously provide sitting / lying and storage functions.
[0005] To achieve the above objectives, this utility model discloses a box-type folding bed. The box-type folding bed includes a box body comprising two opposing shells. The two shells are hinged together on their longitudinal first sides, and their longitudinal second sides can be opened and closed relative to each other. A first bed board, capable of flipping inwards towards the concave side of the first side, is hinged to the opening edge of each shell. A second bed board is hinged to the free side of the first bed board. When the two shells are opened relative to each other, the first and second bed boards can be flattened. When the second bed board flips to the back of the first bed board and the first bed board flips inwards towards the concave side of the shell it is hinged to, the two shells can be locked together. With this structure, the box-type folding bed can be folded into a box or unfolded into a bed. When unfolded into a bed, the bed board is firm, preventing fatigue during long periods of rest. When folded into a box, the box can store bedding or other items, facilitating cleanliness and easy movement.
[0006] Furthermore, a first support plate and a second support plate are hinged to the back of the second bed board. Both the first and second support plates have a close-fitting state near the second bed board and an unfolded state relative to the second bed board. The unfolded height of the first support plate is less than that of the second support plate. An auxiliary support plate is hinged to the first support plate. The auxiliary support plate has a close-fitting state near the first support plate and an unfolded state relative to the first support plate. When both the first and auxiliary support plates are in the close-fitting state, the auxiliary support plate is sandwiched between the first and second bed boards. Both the first and second support plates are provided with locking mechanisms between themselves and the second bed board to fix them in the close-fitting state. The first and auxiliary support plates in the unfolded state are used to support the second bed board when the first and second bed boards are flattened and the free side of the second bed board is raised. With the above structure, when the first and second bed boards are in a flattened state, the first support plate and auxiliary support plate can be unfolded to support the second bed board, ultimately transforming the box-type folding bed into a flat bed. After the second support plate is unfolded, one of the free sides of the second bed board can be raised, ultimately transforming the entire box-type folding bed into a semi-reclining bed.
[0007] Furthermore, the back of the second bed board is provided with several extension blocks, each with a first pin hole, and the back of the box shell is provided with several second pin holes. When the first bed board is flipped toward the concave side of the box shell to which it is hinged, and the second bed board to which it is hinged is flipped to be close to the second longitudinal side of the box shell, the first pin holes can be aligned with the second pin holes. With the above structure, when the two box shells are fastened together, the second bed board on one of the box shells can be flipped to be close to the second longitudinal side of the box shell. After the first pin holes are aligned with the second pin holes, a fixing pin is inserted, ultimately transforming the box-type folding bed into a seat position.
[0008] Furthermore, both sides of the outer shell have outward-flared edges, and both sides of the first bed board have claws. The outward-flared edges have claw holes that match the claws. When the first bed board is flipped towards the concave side of the shell to which it is hinged, the claws can be inserted into the claw holes. The second side of the outer shell has a receiving notch. The longitudinal length of the first bed board is set such that when it is flipped towards the concave side of the shell to which it is hinged, its free side can rest on the receiving notch. The transverse width of the second bed board is set such that when the first bed board is raised relative to the shell, its free side can be inserted into the shell. With this structure, when the outer shell is opened, the first bed board can rest on the outward-flared edges and the receiving notch to maintain its flat state. Inserting the free side of the second bed board into the shell allows the folding bed to transform into a beach chair, a recliner, a chair, or a table.
[0009] Furthermore, the hinged portions of the first and second bed boards are respectively provided with multiple first protrusions and second protrusions. The first protrusions are spaced apart along the edge of the first bed board, and the second protrusions are spaced apart along the edge of the second bed board, with the first and second protrusions staggered. One of the first and second protrusions is provided with a convex shaft, and the other is provided with a shaft recess. The first and second bed boards are hinged together by the cooperation of the convex shaft and the shaft recess. The receiving notch of the box shell is provided with first teeth and second teeth, and the first and second protrusions are respectively provided with first tooth recesses and second tooth recesses. When the second bed board is flipped to the back of the first bed board and the first bed board is hinged to the box, After the concave side of the shell is flipped, the first and second teeth are inserted into the first and second tooth sockets, respectively. The first bed board has a first notch on its free side, and the second bed board has a corresponding second notch on its adjacent side. A connecting handle is located at the first notch. The longitudinal second sidewall of the shell is recessed inward to form a through groove. A third tooth is located at the accommodating notch of the shell, at the opening of the through groove. A third tooth socket is located at the edge of the first notch of the first bed board. When the second bed board is flipped to the back of the first bed board and the first bed board is flipped towards the concave side of the shell to which it is hinged, the third tooth is inserted into the third tooth socket. At this time, the through grooves on both shells are aligned with the first and second notches. With the above structure, the first and second protrusions are hinged together using a convex shaft and a shaft socket, thus achieving the hinge connection between the first and second bed boards and facilitating their assembly and disassembly. When the shells are snapped together, the first, second, and third teeth are inserted into the first, second, and third tooth sockets respectively, making the shells, the first bed board, and the second bed board fit together more tightly and preventing the first and second bed boards from wobbling. The through grooves on the two shells are aligned with the first and second notches, revealing the connecting handles for easy carrying.
[0010] Furthermore, the two shells are hinged together by several embedded hinges. Each embedded hinge includes two hinged inserts. A mounting groove is provided on the longitudinal first side of the shell, extending from near the shell's opening to a point away from the opening and penetrating the bottom surface of the shell. The insert is inserted into the mounting groove from the opening where it penetrates the bottom surface of the shell. A fixing hole is provided on the groove wall near the shell's opening, and a fixing bolt is inserted into the fixing bolt to secure the insert to the shell. With this structure, the embedded hinge uses a combination of mounting and fixing bolt connection, allowing the insert to be tightly fitted to the shell, thus enhancing the shell's strength. The embedded hinge is also easy to assemble and disassemble.
[0011] Furthermore, the width of the mounting groove gradually increases from the part near the edge of the housing to the part away from the edge of the housing. The groove wall near the edge of the housing has a concave insertion groove. The groove opening through the bottom surface of the housing has two left and right limiting grooves. The width of the mounting block gradually increases from one end near another mounting block to match the mounting groove. One end of the mounting block near another mounting block has an insertion part that matches the insertion groove. The other end of the mounting block has two left and right limiting protrusions that match the limiting groove. One side of the insertion part has a connecting block. The free end of the connecting block has several lugs with hinge shaft holes. The lugs on the two connecting blocks are staggered. The two connecting blocks are hinged together by a hinge shaft passing through the hinge shaft hole. The side of the mounting block away from the mounting groove has an outwardly protruding support block with an expansion hole. With the above structure, the insert block and insert groove have a gradually increasing width, facilitating the insertion of the insert block into the insert groove when installing the embedded hinge. The insertion part mates with the insertion groove, and the two limiting protrusions mate with the two limiting grooves respectively, to keep the insert block within the insert groove. The insert block adopts a mortise and tenon-like installation structure and is finally fixed with fixing bolts, which helps to ensure a tight fit between the insert block and the shell, thereby improving the strength of the shell. In addition, the installation and removal of the embedded hinge is also relatively convenient. The support block is used to support the first side of the other shell when the two shells are opened relative to each other, which can keep the two first bed boards flat or keep the tabletop formed by the two shells flat. In addition, the expansion holes on the support block can also be used for hanging items.
[0012] Furthermore, the box-type folding bed also includes an extension plate that can be installed inside the box shell, and can be installed on the horizontal edges of the box shell, the free side of the first bed board, the horizontal edges of the second bed board, or the free side of the second bed board; the longitudinal first side of the extension plate is provided with a left gripper and a right gripper, the horizontal first side of the extension plate is provided with a hook that extends outward from its back, and the horizontal second side of the extension plate is provided with a plug that extends from its back; one inner wall of the box shell is provided with a vertical rib for the left gripper and the right gripper to grip, and the other inner wall and / or bottom wall of the box shell is provided with a slot and / or connector for the edge of the extension plate to enter; the horizontal edges of the box shell, the free side of the first bed board, the horizontal edges of the second bed board, or the free side of the second bed board are provided with connection holes for the hook and / or plug to enter. With the above structure, the extension plate can be installed inside the box shell, at the horizontal edges of the box shell, at the free side of the first bed board, at the horizontal edges of the second bed board, and at the free side of the second bed board to separate the internal space of the box shell, serve as a headrest, extend the width of the bed, extend the length of the bed, or connect two box-type folding beds into a double bed.
[0013] Furthermore, this box-type folding bed also includes several extension arms and several tent feet for connecting elastic support bars or support rods. The bottom surface of the extension arms is connected to extension posts. Each of the two corners of the free side of the second bed board has an extension arm mounting hole that matches the extension post. Multiple extension holes are spaced along the length of the extension arms. When the first and second bed boards are flattened, the extension posts of the extension arms can be inserted into the extension arm mounting holes, and tent feet can be inserted into the extension holes of the extension arms to form a tent base. With this structure, the two box shells can be opened relative to each other, the first and second bed boards can be flattened, the first support plate and auxiliary support plate can be unfolded, and extension arms can be installed at the extension arm mounting holes of the second bed board. Each extension arm has a tent foot inserted into it. The entire box-type folding bed can be transformed into a tent bed base. Elastic support bars or support rods can be connected to the tent feet to form a tent frame. The tent frame supports the tent fabric, making it suitable for outdoor camping. The tent fabric is on top of the bed frame, high off the ground, and is not afraid of water accumulation.
[0014] Furthermore, the box body is equipped with one or more of the following accessories: a pull rod, a lock, and casters. With the above structure, the installation of the pull rod, lock, and casters on the box body facilitates its movement, improving the flexibility of the box-type folding bed.
[0015] In summary, the beneficial effects of this utility model are as follows: This utility model can be combined into a box, unfolded into a bed, and can also transform into a seat, beach chair, table, or tent base. When transformed into a bed, the bed board is firm, making rest comfortable. When combined into a box, the box can store bedding or other items, helping to maintain a tidy environment and facilitating movement. When transformed into a seat, items can be hung on the support blocks of the embedded hinges, such as for mounting fishing rods, bait boxes, sun umbrellas, fishing rod stools, etc., suitable for outdoor fishing. When transformed into a table, it can be used to place camping equipment or goods; goods can be placed there for setting up a stall, and after packing up, the goods can be put back into the box and stored in the trunk of a car. When transformed into a tent base, it can be used for outdoor camping; the tent fabric is on top of the bed frame, high off the ground, preventing water accumulation. The multi-purpose extension panel can divide the internal space of the box shell, widening the width and height of the bed frame, and can also connect two box-type folding beds to form a double bed. In summary, this utility model has multiple states such as a seat, bed, tent base, and suitcase.
