Description

Technical Field

[0001] This invention relates to the field of dormitory bed technology, and in particular to an apartment bed and its installation method. Background Technology

[0002] Apartment beds, as a type of furniture product that efficiently utilizes vertical space, are widely used in dormitories, apartments, children's rooms, and other similar settings. Their structure typically includes corner posts for support and a bed frame to support the mattress. Traditional apartment bed designs have many shortcomings in terms of structural connections, aesthetics, and safety that urgently need improvement.

[0003] Currently, most apartment beds on the market use exposed fasteners to connect the corner posts to the bed frame (usually composed of longitudinal and transverse beams). This involves welding connecting blocks directly to the post surface or using bolts to connect and fix the posts from the outside. This traditional method has several significant drawbacks:

[0004] Insufficient structural stability and safety: Exposed screws, bolts, and other fasteners not only affect the visual appeal but are also more prone to loosening due to daily collisions and vibrations, posing certain safety hazards. The sharp edges of protruding metal parts can easily cause scratches and bumps to users, especially active children.

[0005] Poor aesthetics and difficult to clean: Exposed fasteners and connecting structures detract from the overall appearance of the uprights and the bed frame, giving it a rough and rudimentary look. Furthermore, these protruding parts easily accumulate dust, making cleaning and maintenance very inconvenient.

[0006] Installation is complex and inaccurate: Traditional connection methods often require multi-directional alignment and tightening on-site, making the installation process cumbersome and inefficient. The lack of an effective positioning structure easily leads to installation errors, causing the bed frame to tilt and affecting the overall structural stability and aesthetics.

[0007] Limited structural strength and durability: The connection points are directly exposed to the outside, making them susceptible to external interference and environmental erosion during long-term use, which accelerates the wear and aging of the connectors and affects the overall service life of the product. Summary of the Invention

[0008] This invention aims to at least solve one of the technical problems existing in the prior art. To this end, this invention proposes an apartment bed that provides a concealed connection structure, convenient installation, safety, reliability, and aesthetically pleasing design.

[0009] The present invention also proposes an installation method for the above-mentioned apartment bed.

[0010] On one hand, the apartment bed according to an embodiment of the present invention includes:

[0014] According to some embodiments of the present invention, the corner post further includes a second support portion extending from the body, wherein the extension direction of the first support portion intersects or is opposite to the extension direction of the second support portion, and the first strip groove is provided on the side of the second support portion near the interior.

[0015] According to some embodiments of the present invention, the bed frame further includes a central beam, the two ends of which are connected to the two crossbeams.

[0016] According to some embodiments of the present invention, the system further includes a cabinet and two intermediate columns, the intermediate columns being installed at the intermediate beam or crossbeam on the bed frame, and the cabinet being able to be installed between the corner columns and the intermediate columns.

[0017] According to some embodiments of the present invention, the cabinet includes a cabinet frame, the two corner columns and the two intermediate columns are distributed along the four sides of a rectangle, the cabinet frame includes four support beams and four second connecting plates, the four second connecting plates are located at the four corners of the rectangle, the second connecting plates and the support beams are sequentially and alternately connected to form a frame structure, the two second connecting plates can be respectively installed on the two corner columns, and the two second connecting plates can be respectively installed on the two intermediate columns.

[0018] According to some embodiments of the present invention, at least six corner posts are provided, and two bed frames are provided. Every four corner posts are installed in a rectangular arrangement to form at least two rectangular installation areas. The two bed frames are respectively located in the two rectangular installation areas and installed on the corresponding corner posts.

[0019] According to some embodiments of the present invention, a ladder is also included, the ladder comprising:

[0020] The main beam is inclined.

[0021] Multiple pedals are arranged sequentially along the extension direction of the main beam;

[0022] An armrest is located around the footboard, and one end of the armrest is used to connect to the bed frame.

[0023] On the other hand, the apartment bed according to an embodiment of the present invention includes the following steps:

[0024] The bed frame is assembled by arranging the two longitudinal beams and two transverse beams on the four sides of a rectangle, connecting the first connecting part of the first connecting plate to the longitudinal beam, and connecting the second connecting part of the first connecting plate to the transverse beam. The longitudinal beams, the connecting plate and the transverse beam are connected together to form an overall frame.

[0025] Install the corner posts, and install the four corner posts on the first connecting plate respectively.

[0026] According to some embodiments of the present invention, the method further includes the following steps:

[0027] Install the cabinet frame, with four support beams arranged along the four sides of a rectangle. Alternately weld the four support beams and four second connecting plates to form a frame structure.

[0028] Install the middle uprights, install two of the second connecting plates of the cabinet frame on the corner uprights, and install the two middle uprights on the other two second connecting plates of the cabinet frame;

[0029] Install the base plate and attach it to the cabinet frame.

[0030] Install the top panel and attach it to the bed frame.

[0031] On the other hand, the installation method according to an embodiment of the present invention includes an apartment bed according to the above embodiment of the present invention.

[0032] The embodiments of the present invention have at least the following beneficial effects:

[0033] As the core supporting component of the bed frame, the structural stability of the uprights directly affects the load-bearing capacity and service life of the bed frame. By setting a first strip-shaped groove arranged along the extension direction on the inner side of the uprights, and configuring a first mounting hole or hanging hole in the groove, an assembly scheme that combines connection strength and visual concealment is formed.

[0034] When installing the back panel or side panel, connectors (such as screws, bolts, pins, etc.) can be inserted into the first mounting hole through the first slot to achieve a secure connection between the uprights and the panel. This design completely conceals all fasteners within the slot and the bed frame, with no exposed parts visible from the outside. This not only maintains the clean and minimalist aesthetic of the bed frame but also avoids the problems of dust accumulation and difficulty in cleaning traditional exposed screws.

[0035] In terms of safety, the concealed design completely eliminates the risk of bumps and knocks from protruding screw heads, making it especially suitable for families with elderly people or children, effectively reducing the possibility of accidental scratches. At the same time, the connectors are located inside the bed frame, reducing direct contact with the external environment and significantly preventing loosening or detachment due to contact or vibration during long-term use. This further enhances the stability and durability of the bed structure and extends its overall service life.

[0036] The longitudinal beams, the first connecting plate, and the crossbeams are connected sequentially to form a stable overall frame, serving as the core load-bearing structure of the bed frame. The main body of the bed frame can be prefabricated by welding; during installation, only the first connecting plate needs to be aligned with the corner posts, greatly simplifying the on-site assembly process and significantly improving installation efficiency. Simultaneously, the first connecting plate also serves a positioning function, ensuring accurate alignment of each corner post with the connection point, avoiding installation deviations, and improving construction accuracy and overall aesthetics. This structure is rationally designed, clearly constructed, and combines good structural strength with ease of construction.

[0037] After the first connecting plate is installed on the corner post, due to the design of the first slot, the first connecting plate is installed on the inner surface of the post, while the connection position of the post with other components is located in the first slot. The surface of the post and the installation structure in the first slot will not interfere with each other.

[0038] Additional aspects and advantages of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0073] Reference Figures 1-18 A basic embodiment of the first aspect of the present invention provides an apartment bed, comprising:

[0074] Three or four corner posts 100, with a first strip groove 110 and a mounting groove on the inner side, the first strip groove 110 is provided along the extension direction of the corner post 100, and the first strip groove 110 is provided with a first mounting hole 111 and / or hanging hole 112.

[0075] The bed frame 200 includes two longitudinal beams 210, two transverse beams 220, and three or four first connecting plates 230. The two longitudinal beams 210 and two transverse beams 220 are arranged along the four sides of a rectangle. The four first connecting plates 230 are located at at least three corners of the rectangle. Each first connecting plate 230 includes a first connecting part connecting the longitudinal beams 210 and a second connecting part connecting the transverse beams 220. The first connecting plate is equipped with a hook. The first connecting plate 230 is connected to the corner posts 100. The longitudinal beams 210, the first connecting plates 230, and the transverse beams 220 are connected to form an overall frame. The hook can be hooked into the mounting groove so that the bed frame 200 is installed on the corner posts 100.

[0076] According to embodiments of the present invention, by such a configuration, at least the following effects can be achieved:

[0077] As the core supporting component of the bed frame, the structural stability of the upright directly affects the load-bearing performance and service life of the bed frame. By setting a first strip groove 110 arranged along the extension direction on the inner side of the upright, and configuring a first mounting hole 111 or hanging hole 112 in the groove, an assembly scheme that combines connection strength and visual concealment is formed.

[0078] When installing the back panel or side panel, connectors (such as screws, bolts, pins, etc.) can pass through the first mounting hole 111 from inside the first slot 110 to achieve a secure connection between the upright and the panel. This design completely conceals all fasteners within the slot and the bed frame, with no exposed parts visible from the outside. This not only maintains the clean and minimalist aesthetic of the bed frame but also avoids the problems of dust accumulation and difficulty in cleaning traditional exposed screws.

[0079] In terms of safety, the concealed design completely eliminates the risk of bumps and knocks from protruding screw heads, making it especially suitable for families with elderly people or children, effectively reducing the possibility of accidental scratches. At the same time, the connectors are located inside the bed frame, reducing direct contact with the external environment and significantly preventing loosening or detachment due to contact or vibration during long-term use. This further enhances the stability and durability of the bed structure and extends its overall service life.

[0080] The longitudinal beam 210, the first connecting plate 230, and the transverse beam 220 are connected sequentially to form a stable overall frame, serving as the core load-bearing structure of the bed frame. The main body of the bed frame can be prefabricated by welding; during installation, only the first connecting plate needs to be aligned with the corner posts 100, greatly simplifying the on-site assembly process and significantly improving installation efficiency. Simultaneously, the first connecting plate 230 also serves a positioning function, ensuring accurate alignment of each corner post 100 with the connection point, avoiding installation deviations, and improving construction accuracy and overall aesthetics. This structure is rationally designed, clearly constructed, and combines good structural strength with ease of construction.

[0081] The positioning of the hooks and mounting slots enables the bed frame 200 and corner posts 100 to be quickly positioned and installed, allowing the bed frame to be quickly connected to the corner posts 100. Bolts, screws and other structures can then be used to pass through the bed frame and corner posts to connect them, further improving the connection stability between the bed frame and corner posts.

[0082] After the first connecting plate 230 is installed on the corner post 100, due to the design of the first strip groove 110, the first connecting plate 230 is installed on the inner surface of the post, while the connection position of the post with other components is located in the first strip groove 110. The surface of the post and the installation structure in the first strip groove 110 will not interfere with each other.

[0083] It should be noted that the longitudinal beams 210 and the transverse beams 220 can also be directly connected by welding or indirectly connected by connecting plates. The bed frame 200 can be positioned by three to four first connecting plates 230. Since three points are used to position a plane, at least three connecting plates are needed to position the bed frame 200 and the uprights. If only three connecting plates are used for positioning, the final corner position is supported by an upright structure located below the bed frame 200. The bed frame 200 and the uprights abut against each other and are then connected by bolts or other structural means.

[0084] It should be noted that the inner side of the upright refers to the side closest to the inside of the bed after the upright is installed, while the outer side of the upright refers to the side closest to the perimeter of the bed after the upright is installed.

[0085] In some embodiments, the cross-section of the first strip groove 110 is a semi-circular arc cross-section or a rectangular cross-section. The cross-section of the first strip groove 110 can be designed in different shapes such as semi-circular arc or rectangle to meet diverse engineering needs.

[0086] In some embodiments, the first mounting hole 111 can penetrate the column. The first mounting hole 111 can penetrate the column, allowing the locking member to be inserted from the inside out, thereby achieving reliable locking of the bed side panel from the inside and preventing the locking member from being exposed on the outside.

[0087] In some embodiments, the corner post 100 includes a body and a first support portion 130 extending from the body. A first strip groove 110 is provided on the side of the first support portion 130 near the interior, and a first stepped groove 131 is provided on the side of the first support portion 130 away from the first strip groove 110. The bed side panel can be embedded in the stepped groove to make its outer surface flush with the outer surface of the post, avoiding unevenness that affects aesthetics, reducing the risk of scratches, and improving safety during use.

[0088] In some embodiments, the corner post 100 further includes a second support portion 140 extending from the body, wherein the extending direction of the first support portion 130 intersects or is opposite to the extending direction of the second support portion 140, and a first strip groove 110 is provided on the inner side of the second support portion 140. The post may also include a second support portion 140 whose extending direction intersects or is opposite to that of the first support portion 130, and a second surface is provided on the inner side of the second support portion 140 to support more diverse panel mounting layouts.

[0089] In some embodiments, the bed frame 200 further includes a central beam 240, the two ends of which are connected to two crossbeams 220. The central beam 240 spans between the opposing crossbeams 220, significantly enhancing the rigidity and deformation resistance of the overall structure and improving the stability of the bed frame under load.

[0090] In some embodiments, the bed frame 200 further includes a plurality of reinforcing beams 250, the two ends of which are connected to two crossbeams 220. This improves the stability of the bed frame under load.

[0091] refer to Figures 10-15 In some embodiments, the system also includes a cabinet 400 and two intermediate columns 300, with the intermediate columns 300 mounted on the intermediate beam 240 or crossbeam 220 of the bed frame 200, and the cabinet 400 can be installed between the corner column 100 and the intermediate columns 300.

[0092] In some embodiments, the cabinet 400 includes a cabinet frame 410, two corner posts 100 and two intermediate posts 300 distributed along the four sides of a rectangle. The cabinet frame 410 includes four support beams 411 and four second connecting plates 412. The four second connecting plates 412 are located at the four corners of the rectangle. The second connecting plates 412 and the support beams 411 are alternately connected to form a frame structure. The two second connecting plates 412 can be installed on the two corner posts 100 and the two second connecting plates 412 can be installed on the two intermediate posts 300 respectively.

[0093] In this configuration, the two corner columns 100 and the two intermediate columns 300 constitute the core support system of the cabinet, providing a stable mechanical foundation for the overall structure. The cabinet frame is formed by connecting multiple support beams 411 and the second connecting plate 412 in sequence, and can be manufactured into an integrated cabinet frame structure using welding technology, which has high integrity and load-bearing capacity.

[0094] This design significantly simplifies the cabinet assembly process and greatly improves construction efficiency. The second connecting plate 412 not only serves as a connector but also positions the columns, ensuring accurate positioning and consistent spacing of each column. This effectively avoids installation difficulties caused by misalignment and is particularly suitable for rapid on-site assembly. After the columns and cabinet frame are assembled, a stable support system is formed, upon which side panels and other functional components can be installed, ultimately completing the overall construction of the cabinet.

[0095] In addition, the structure supports modular expansion, allowing multiple cabinet frames to be installed sequentially along the column height according to actual needs, thereby achieving flexible vertical layering and functional zoning of the cabinets, enhancing the adaptability of the design and ease of use.

[0096] It should be noted that the cabinet frame and the bed frame 200 have similar structures. The bed frame 200 can be positioned to locate the four corner posts 100. The position of the cabinet frame can be determined based on the positions of two corner posts 100, and then the position of the middle post 300 can be determined.

[0097] It should be noted that the connecting plate is equipped with a hook, and the column is equipped with a hanging hole 112. The connection between the hook and the hanging hole 112 allows the connecting plate to be installed on the column; or, the connecting plate and the column can be fixed to the column by bolts or screws through a threaded connection.

[0098] It should be noted that one or more bed frames can be installed on the same column 100 to form a bunk bed with a table underneath or a bunk bed, to accommodate different numbers of guests.

[0099] In some embodiments, the cabinet 400 further includes a base plate 420, and the support beam 411 is provided with a second stepped groove 413, into which the base plate 420 is embedded. The support beam 411 is provided with a first stepped groove 131, and the base plate 420 is embedded in the groove to achieve concealed installation, avoiding protrusion that affects visual aesthetics. By inserting screws through the first connecting holes on the support beam 411210 and the base plate 420, the base plate 420 can be further securely fixed to the cabinet frame.

[0100] In some embodiments, a top plate 430 is also included, which includes a body and an extension 431 extending from the body. The extension 431 is mounted on the intermediate beam 240, the longitudinal beam 210, and / or the transverse beam 220. The top plate 430 of the cabinet 400 can be mounted on the bed frame 200. Since the top plate 430 of the cabinet 400 is not under stress, it can be simply installed and connected, making it more convenient to mount on the bed frame 200.

[0101] In some embodiments, the system further includes a shelf 500, and the column is provided with hanging holes 112. The hanging holes 112 are located within the first strip groove 110, and the shelf 500 can be installed in the hanging holes 112. The first strip groove 110 may also be provided with a plurality of hanging holes 112 arranged sequentially along the extension direction of the column for hanging the shelf 500. The user can flexibly adjust the installation height of the shelf 500 according to actual needs.

[0102] In some embodiments, at least six corner posts 100 and two bed frames 200 are provided. Each set of four corner posts 100 is arranged in a rectangular pattern to form at least two rectangular installation areas. Two bed frames 200 are respectively located within two rectangular installation areas and mounted on the corresponding corner posts 100. A single dormitory bed can have at least one bed frame 200, accommodating two users. By setting two beds and providing six corner posts 100 (where the two middle corner posts 100 can be shared), or eight corner posts 100, forming two rectangular installation areas, two bed frames 200 can be mounted on the posts, saving space.

[0103] refer to Figures 16-18 In some embodiments, a ladder 600 is also included, the ladder 600 comprising:

[0104] Main beam 610, main beam 610 is inclined;

[0105] Multiple pedals 620 are arranged sequentially along the extension direction of the main beam 610;

[0106] Armrest 630, the armrest is located around the footboard 200, and one end of the armrest is used to connect to the bed frame.

[0107] In this configuration, the main beam 610 adopts an inclined layout, allowing the steps 620 to be arranged sequentially along its extension direction, forming an ergonomic climbing path. Compared to the upright ladder 600, this makes it easier for users to move up and down, effectively reducing physical exertion and operational burden, while also lessening the stress on the knees and lower back. The handrail 630 is fixed at one end to the step 620 and connected to the bed frame at the other end, providing users with continuous and stable grip support, enhancing assistance and safety during climbing, and also strengthening the overall structural rigidity and torsional stability, significantly suppressing swaying or lateral deviation during use. Furthermore, the ladder 600 is assembled from a single main beam 610, several steps 620, and handrails 630, resulting in a simple structure, economical material use, reduced manufacturing costs, and ease of transportation, rapid on-site installation, and subsequent maintenance.

[0108] In some embodiments, the main beam 610 is provided with a mounting rod 611, which can be inserted into the pedal 620, so that the mounting rod 611 and the pedal 620 can be installed and fixed. The mounting rod 611 is welded to the main beam 610 and fixedly installed on the main beam 610. By inserting the mounting rod 611 into the pedal 620, the mounting rod 611 and the pedal 620 can be quickly spliced ​​together, and the mounting rod 611 can be fixedly installed on the pedal 620 by a locking structure such as bolts.

[0109] In some embodiments, the pedal 620 includes a first support portion 621, a second support portion 622, and a foot pedal portion 623. The first support portion 621 is disposed on the main beam 610, the second support portion 622 extends from the middle of the first support portion 621, and the foot pedal portion 623 is disposed on the first support portion 621 and the second support portion 622. The first support portion 621 and the second support portion 622 form a cross-shaped structure. This design effectively increases the overall area of ​​the support structure, thereby effectively increasing the contact area between the foot pedal portion 623 and the support structure. This makes the installation of the foot pedal portion 623 more stable, providing users with more reliable foot support and further improving safety and stability during climbing.

[0110] Furthermore, some friction textures can be set on the pedal 620 to increase the friction between the foot and the pedal 620, thus playing a role in preventing slippage.

[0111] In some embodiments, the foot pedal 623 includes a first cover plate 631 and a second cover plate 632, which cover the first support portion 621 and the second support portion 622. The first cover plate 631 and the second cover plate 632 are connected by a locking member. The first cover plate 631 and the second cover plate 632 are respectively disposed on the upper and lower sides of the first support portion 621 and the second support portion 622. This structural design not only allows the first cover plate 631 and the second cover plate 632 to cover the outer side of the first support portion 621 and the second support portion 622, effectively preventing the support structure from being exposed to the outside and avoiding erosion and damage from the external environment due to long-term exposure, thus extending the service life of the pedal 620, but also provides users with a more comfortable and clean foot pedal surface, improving the overall aesthetics of the product.

[0112] In some embodiments, handrails 630 are disposed around the periphery of the two or three upper footboards 620. The handrails 630 provide continuous and stable grip support for the user, allowing for easier and more stable vertical movement during climbing, significantly improving assistance and safety. Connecting the two or three footboards 620 in this design extends the length of the handrails 630, providing a longer grip area and further enhancing the structural stability of the entire ladder.

[0113] In some embodiments, the handrail 630 sequentially includes a first handrail, a support rod, and a second handrail. The first and second handrails are symmetrically arranged on both sides of the footrest, and the support rod is located below one of the footrests. The first and second handrails are respectively used to connect two window frames. This symmetrically arranged handrail 630 not only facilitates the user's hand grip, providing a more balanced and stable grip, but also, by connecting the two bed frames, it also provides a fixing effect on the two bed frames, enhancing the overall stability of the bed frame. Furthermore, a ladder can simultaneously provide access to both beds, greatly improving the efficiency and convenience of the ladder and meeting the needs of multiple users.

[0114] In some embodiments, the main beam 610 includes a main body and a mounting portion disposed on the main body, and the step 620 is disposed on the mounting portion, the width of which is greater than the width of the main beam 610 main body. This design increases the strength of the main beam 610, enabling it to better withstand the weight and force applied by the user during climbing, further improving the overall stability and reliability of the ladder 600.

[0115] In some embodiments, mounting holes are provided between the two bed frames 200 and the uprights 700, and the two bed frames 200 and the uprights 700 can be connected together by bolts or screws to form a complete double bed structure.

[0116] In some embodiments, the ladder 610 is further included with a support plate 700 mounted on the bed frame 200. The support plate 700 has a support plane, and the main beam 610 abuts against the support plane. The support plane on the support plate 700 can provide effective support for the main beam 610, improve the stability of the main beam 610, and ensure that the ladder 600 will not sway or tilt during use.

[0117] In some embodiments, the system further includes two bed frames that abut against each other to form an inner groove, into which the main beam 610 can be inserted. Insertion of the main beam 610 into the inner groove serves to limit its position, preventing displacement and improving its strength.

[0118] A basic embodiment of the second aspect of the present invention, an installation method applied to an apartment bed, includes the following steps:

[0119] The bed frame 200 is assembled by arranging two longitudinal beams 210 and two transverse beams 220 on the four sides of a rectangle. The first connecting part of the first connecting plate 230 is connected to the longitudinal beam 210, and the second connecting part of the first connecting plate 230 is connected to the transverse beam 220. The longitudinal beams 210, the connecting plate and the transverse beam 220 are connected to form an overall frame.

[0120] Install the corner posts 100, and install the four corner posts 100 on the first connecting plate 230 respectively.

[0121] In some embodiments, the following steps are also included:

[0122] Install the cabinet frame, with four support beams arranged along the four sides of a rectangle. Alternately weld the four support beams and four second connecting plates to form a frame structure.

[0123] Install the middle uprights, install two of the second connecting plates of the cabinet frame on the corner uprights, and install the two middle uprights on the other two second connecting plates of the cabinet frame;

[0124] Install the base plate and attach it to the cabinet frame.

[0125] Install the top panel and attach it to the bed frame.

[0126] In this installation method, the bed frame is used for initial positioning to determine the position of the corner posts. Then, the position of the cabinet frame is determined by the position of the corner posts. The cabinet frame can be installed on the corner posts. The middle posts are then installed through the corner posts, reducing the difficulty of positioning.
