TECHNICAL FIELD

[0001] The utility model relates to bed body structure, in particular to a guardrail structure installed at the side of bed for safety protection. BACKGROUND

[0002] Bed is a kind of necessary article to meet the daily sleep of human, and the shape and specification of bed are different according to the use group and different scenes.For example, in the family housing, people hope that the bed can have larger width under the condition of allowing, and the bed with sufficient width generally does not need to install guardrail;But for some limited conditions, such as student dormitory, the bed they use not only has limited width (about 800-900mm wide), but also often needs to use the structure of upper and lower double beds to reduce the occupation of space, and the edge of the bed of these student beds, especially the upper bed, generally installs guardrail to avoid students falling from the bed when sleeping.

[0003] The existing bed guardrail is all straight plate structure, or all connecting rods are arranged on the same plane of plane frame structure, and these bed guardrails are all flat, but the material itself still has certain thickness, which inevitably occupies the narrow space in the bed after being installed to the side of bed, and brings bad use experience to users.

[0004] The Chinese utility model patent with publication number CN219845824U discloses a bed guardrail structure, which uses sheet material bending to install guardrail column on the beam of bed body, two L-shaped locking hooks are arranged at the bottom of guardrail column, the locking hooks are inserted into the lock hole in the beam, and then the locking hooks are pulled to realize fixation. Thus, the contact area between guardrail column and bed edge beam is increased, so that the engagement stress intensity and connection strength of guardrail column and bed body are improved. However, the volume and area of locking hook are small, and it is difficult to effectively provide sufficient contact area, so that the connection strength between guardrail column and beam cannot be guaranteed.

[0009] Furthermore, the bottom of the upright extends outward and upward from the edge of the bed, is vertically set in the middle, and the top is an arc extending from the outside of the bed to the inside of the bed.

[0010] Furthermore, the uprights are made of bent sheet metal, with an opening on one side facing the inside of the bed. The lower part of the end of the upright is a support part, and pressure plates extend outward from both sides of the upper part of the end of the upright. Locking hooks are set in the middle of the bottom surface of the pressure plates, and the ends of the two pressure plates are connected by a beam plate, which is the clamping part.

[0011] Furthermore, the two sides of the column are made of bent sheet metal, and the edges of the sheet metal on both sides are welded or connected together by butt plates.

[0028] This utility model proposes a bed guardrail structure.

[0029] Example 1, as Figures 1-7 As shown.

[0030] The bed rail structure described in this embodiment includes a hollow crossbeam 1 located at the outer edge of the bed, with two or more uprights 2 installed side by side on the crossbeam, and a crossbar 3 connecting adjacent uprights; the top surface of the crossbeam and each upright is provided with two or more locking holes 11; the bottom of the uprights extends arc-shaped from the crossbeam to the upper outer edge of the bed, and the bottom end of the upright extends downward to form a support part 21 that abuts against the outer side of the crossbeam, and the bottom end of the upright extends laterally to form a pressing part 22 that presses against the top surface of the crossbeam, and the bottom surface of the pressing part is provided with two or more locking hooks 4 that are inserted into the corresponding locking holes, and the ends of the locking hooks extend along the top surface inside the crossbeam and contact each other.

[0031] The aforementioned bed rail structure has uprights installed on the crossbeams along the outer edge of the bed, and the uprights are connected by crossbars to form a protective structure to prevent the user from falling off the outer edge of the bed. The bottom of the uprights is installed on the crossbeams, and on the one hand, it abuts against the side and top surface of the crossbeams through the support and clamping parts, and on the other hand, it is inserted into the locking holes of the crossbeams through the locking hooks, thus forming multi-faceted contact and positioning, and then the uprights and crossbeams are welded and fixed. The bottom of the uprights is arc-shaped outward to form an expansion space.

[0032] The bed rail structure described above features several stepped surfaces on the inner side of the crossbeam 1. This facilitates the placement of the bed board and enhances the structural strength of the crossbeam. The bottom of the upright 2 extends outwards and upwards from the edge of the bed, is vertically positioned in the middle, and has an arc-shaped top extending from the outside of the bed inwards and upwards, forming a bracket-like structure. This provides sufficient protective space for the user, while the arc-shaped top also acts as a vertical limit, serving as a reminder when the user gets up and preventing their center of gravity from shifting outwards and pressing against the bed frame.

[0033] The described bed rail structure includes a top bar 31 connected to the top of the upright 2 and a stop bar 32 connected to the middle of the upright. The upright 2 has through holes for the stop bar to pass through, allowing the stop bar to pass through all the uprights simultaneously and connect them as a single unit. Additionally, mounting grooves 5 are provided on the opposite sides of adjacent uprights 2 and on the bottom surface of the stop bar 32. A light-blocking panel (not shown) is also provided; its two sides and top edge are respectively located within the mounting grooves of the uprights and the stop bar. The light-blocking panel enhances the privacy of the bed by obstructing the view, while a ventilation space is left between the stop bar and the top bar to ensure ventilation.

[0034] Example 2, as Figure 8 As shown.

[0035] In the bed rail structure described in this embodiment, on the top surface of the crossbeam 1, on the side adjacent to the support part 21 of the upright 2, that is, between the support part and the clamping part of the upright, there is an upwardly extending boss 13. The upright is provided with a slot for the boss to be inserted at the position opposite to the boss; the rest is the same as in Embodiment 1.

[0036] During use, this type of bed rail structure provides support for the uprights when the rail is subjected to inward pressure. The uprights are primarily supported by the clamping part and the crossbeam. When the rail is subjected to outward pressure, the uprights are primarily supported by the support part and the slot, which clamp the boss from both the inside and outside. Throughout the entire process, the locking hook no longer bears the force alone, but rather plays a limiting and auxiliary role in bearing the force. Furthermore, all contact points between the uprights and the crossbeam are surface contacts, which significantly increases the force-bearing area and makes the force distribution more reasonable. The locking hook is less prone to fatigue fracture caused by repeated stress, greatly improving the connection strength and ensuring the safety of the rail connection.

[0037] Example 3, as Figure 9 As shown.

[0038] The bed rail structure described in this embodiment features a post 2 made of bent sheet metal. The post has an opening on one side facing inwards towards the bed. The lower part of the post's end is a support section 21. Pressure plates 24 extend outwards from both sides of the upper part of the post's end. A locking hook 4 is located in the center of the bottom surface of the pressure plates. The ends of the two pressure plates are connected by a beam plate, which serves as the clamping part 22. An upward-facing boss is provided between the support section of the post and the beam plate of the post. An upward-facing vertical section is provided on the side of the beam plate adjacent to the boss, abutting against the inner side of the boss.

[0039] The bed rail structure described above features uprights whose bottom extends in an arc from the crossbeam towards the outer edge of the bed. The degree of curvature at the bottom of the upright determines the expanded bed space; a greater curvature results in a larger expanded bed space, better contact between the expanded area and the bed surface, and greater comfort. To achieve greater expansion space and a better user experience, the curvature at the bottom of the upright needs to be as large as possible. However, existing uprights are typically tubular, one-piece structures made of iron or steel. Due to the properties of the materials, it is difficult to achieve a large degree of curvature during bending, thus limiting the expansion of bed space. To better expand bed space and further improve comfort, the uprights can be constructed from welded sheet metal. The two sides of the upright 2 are formed by bending sheet metal, with the edges of the sheet metal on both sides welded or connected together using butt plates. This allows the upright to be tubular and facilitates different bending processes on each sheet metal piece, thereby increasing the structural strength of the upright and allowing for a greater curvature at the bottom of the upright, thus better expanding bed space and improving user comfort.

[0040] Example 4, as Figure 10 As shown.

[0041] The bed rail structure described in this embodiment can also be as follows: Figure 10 As shown, the crossbeam 1 has an upward-facing protrusion 13 between the support part 21 of the column 2 and the beam plate of the column. An upward-facing vertical part is provided on the side of the beam plate adjacent to the protrusion, which abuts against the inner side of the protrusion. When the guardrail is subjected to outward pressure, the column part is mainly supported by the support part abutting against the outer side of the crossbeam and the vertical part of the beam plate abutting against the inner side of the protrusion, which together clamp the protrusion from the inside and outside. Throughout the entire use process, the locking hook no longer bears force independently, but rather plays a limiting and auxiliary force-bearing role. Furthermore, the horizontal part of the beam plate and the crossbeam, the vertical part of the beam plate and the protrusion of the crossbeam, and the support part of the column and the outer side of the crossbeam are all in surface contact, significantly increasing the force-bearing area and thus improving the connection strength.

[0042] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
