Description

Technical Field

[0001] The invention relates to a bed structure, in particular to a guardrail structure installed at the side of a bed for safety protection. Background Art

[0002] A bed is a necessity for people to sleep. The shape and specifications of a bed vary depending on the user group and different scenarios. For example, in a family home, if conditions permit, people hope that the bed can be wider. A bed with sufficient width generally does not need to be equipped with guardrails. However, for some environments with limited conditions, such as student dormitories, the beds they use are not only limited in width (about 800-900mm wide), but also often need to use a bunk bed structure to reduce space occupation. These student beds, especially the edges of the upper beds, are generally equipped with guardrails to prevent students from falling off the bed while sleeping.

[0003] Existing bed guardrails are all straight plate structures, or flat frame structures in which all connecting rods are arranged on the same plane. Although these bed guardrails are all straight, the material itself still has a certain thickness. After being installed on the side of the bed, it will inevitably occupy the already narrow space inside the bed, bringing a bad user experience to the user.

[0004] The Chinese utility model patent with publication number CN219845824U discloses a bed guardrail structure, which uses sheet materials to be bent into guardrail posts installed on the crossbeam of the bed body. Two L-shaped locking hooks are set at the bottom of the guardrail posts, and the locking hooks are inserted into the locking holes in the crossbeam, so that they are fixed by pulling with the locking hooks. This increases the contact area between the guardrail posts and the crossbeam along the bed, thereby improving the bite force strength and connection strength of the guardrail posts and the bed body. However, the volume and area of ​​the locking hooks are small, and it is difficult to effectively provide sufficient contact area, and the connection strength between the guardrail posts and the crossbeam cannot be guaranteed. Summary of the invention

[0005] The object of the present invention is to provide a bed guardrail structure capable of increasing the space inside the bed, so as to improve the comfort of the bed.

[0006] The bed guardrail structure described in the present invention includes a hollow crossbeam located at the outer edge of the bed, two or more columns are installed in parallel on the crossbeam, and a crossbar is connected between adjacent columns; two or more clamping holes are respectively provided on the top surface of the crossbeam opposite to each column; the bottom of the column is extended in an arc shape from the crossbeam to the upper outer side of the bed edge, the bottom end of the column extends downward to form a support portion that abuts against the outer side surface of the crossbeam, and the bottom end of the column extends laterally to form a clamping portion that is pressed against the top surface of the crossbeam, and the bottom surface of the clamping portion is provided with two or more locking hooks inserted into the corresponding clamping holes, and the ends of the locking hooks extend along the top surface inside the crossbeam.

[0007] Furthermore, the inner side surface of the crossbeam is provided with a plurality of stepped surfaces.

[0008] Furthermore, a boss extending upward is provided on one side of the top surface of the cross beam adjacent to the support portion of the column, and a slot for inserting the boss is provided on the column at a position opposite to the boss.

[0009] Furthermore, the bottom of the column extends from the edge of the bed to the outside and above, the middle part is vertically arranged, and the top is an arc extending from the outside of the bed to the inside and above the bed.

[0010] Furthermore, the column is formed by bending a sheet material, and an opening on one side of the column is arranged toward the inside of the bed. The lower part of the end of the column is a supporting part, and pressure plates are extended outward on both sides of the upper part of the end of the column respectively. The locking hook is arranged in the middle of the bottom surface of the pressure plate, and the ends of the two pressure plates are connected by a beam plate, and the beam plate is the clamping part.

[0011] Furthermore, both sides of the column are formed by bending sheet materials, and the edges of the sheet materials on both sides are welded or connected as a whole through a butt plate.

[0012] Furthermore, the crossbar includes a top bar connected to the top of the column, and a stop bar connected to the middle of the column, and a through hole for the stop bar to pass through is opened on the column.

[0013] Furthermore, mounting grooves are respectively provided on opposite sides of adjacent columns and on the bottom surface of the barrier rod, and a shielding plate for blocking light is further provided, and both side edges and the top edge of the shielding plate are respectively arranged in the mounting grooves of the columns and the barrier rod.

[0028] The invention provides a bed guardrail structure.

[0029] Embodiment 1, as Figure 1-7 shown.

[0030] The bed guardrail structure described in this embodiment includes a hollow crossbeam 1 located at the outer edge of the bed, two or more columns 2 are installed in parallel on the crossbeam, and a crossbar 3 is connected between adjacent columns; two or more clamping holes 11 are respectively provided on the top surface of the crossbeam opposite to each column; the bottom of the column is extended in an arc shape from the crossbeam to the upper outer side of the bed edge, and the bottom end of the column extends downward to form a support portion 21 that abuts against the outer side surface of the crossbeam, and the bottom end of the column extends laterally to form a clamping portion 22 that is pressed against the top surface of the crossbeam, and the bottom surface of the clamping portion is provided with two or more locking hooks 4 inserted into the corresponding clamping holes, and the ends of the locking hooks extend along the top surface inside the crossbeam and contact each other.

[0031] The bed guardrail structure is characterized in that the upright posts are mounted on the cross beam of the outer bed edge, and the upright posts are connected by cross bars, thereby forming a protective structure for preventing the user from falling from the outer bed edge; the bottom of the upright posts is mounted on the cross beam, and on the one hand, they are abutted against the side and top surfaces of the cross beam through the supporting part and the pressing part, and on the other hand, they are inserted into the clamping holes of the cross beam through locking hooks, thereby forming multi-faceted contact and positioning, and then the upright posts and the cross beam are welded and fixed; the bottom of the upright posts is arranged in an arc shape outward to form an expansion space.

[0032] In the bed guardrail structure, the inner side of the crossbeam 1 is provided with a plurality of stepped surfaces, which can facilitate the placement of the bed board on the one hand, and improve the structural strength of the crossbeam on the other hand. The bottom of the column 2 extends from the edge of the bed to the outside and above, the middle is vertically arranged, and the top is an arc extending from the outside of the bed to the inside of the bed, thereby forming a bracket-like structure. While providing sufficient protection space for the user, the top of the arc arrangement can also form a vertical limit, which can serve as a reminder when the user gets up, to prevent the center of gravity from pressing the bed body outward.

[0033] In the bed guardrail structure, the crossbar 3 includes a top bar 31 connected to the top of the column 2 and a blocking bar 32 connected to the middle of the column. The column 2 is provided with a through hole for the blocking bar to pass through, so that the blocking bar can pass through all the columns at the same time and connect all the columns as a whole. At the same time, the opposite sides of the adjacent columns 2 and the bottom surface of the blocking bar 32 are respectively provided with mounting grooves 5, and there is also a shielding plate (not shown) for blocking light. The two side edges and the top edge of the shielding plate are respectively set in the mounting grooves of the column and the blocking bar. The shielding plate blocks the line of sight, thereby improving the privacy of the bed, and the space between the blocking bar and the top bar is left empty as a ventilation space, thereby ensuring ventilation.

[0034] Embodiment 2, as Figure 8 shown.

[0035] The bed guardrail structure described in this embodiment has an upwardly extending boss 13 on the top surface of the beam 1 adjacent to the supporting portion 21 of the column 2, that is, between the supporting portion and the clamping portion of the column, and the column is provided with a slot for inserting the boss at a position opposite to the boss; the rest is the same as in the first embodiment.

[0036] During use of this bed guardrail structure, when the guardrail is subjected to inward pressure, the column part is mainly subjected to the force of the clamping part and the crossbeam. When the guardrail is subjected to outward pressure, the column part is mainly subjected to the force of the boss clamped by the support part and the slot from the inside and outside. During the whole use process, the locking hook no longer bears the force alone, but plays a more limiting and auxiliary force-bearing role. Moreover, all contact positions between the column and the crossbeam are surface contacts, and the force-bearing area is greatly increased. The force is more reasonable, and the locking hook is not prone to fatigue fracture caused by repeated force, which greatly improves the connection strength and ensures the safety of the guardrail connection.

[0037] Embodiment three, as Fig. 9 shown.

[0038] The bed guardrail structure described in this embodiment is formed by bending a sheet material, and the column 2 is opened on one side of the column facing the inside of the bed. The lower part of the end of the column is a support part 21, and the two sides of the upper part of the end of the column extend outwardly with a pressure plate 24, and the lock hook 4 is arranged in the middle of the bottom surface of the pressure plate. The ends of the two pressure plates are connected by a beam plate, which is the clamping part 22. The cross beam is provided with an upward boss between the support part of the column and the beam plate of the column, and the beam plate of the column is provided with an upward vertical part on the adjacent side of the boss to abut against the inner side of the boss.

[0039] The bed guardrail structure has a bottom of a column extending from the crossbeam to the upper side of the bed in an arc shape. The curvature of the arc at the bottom of the column will determine the bed surface space it expands. The greater the curvature of the bottom, the larger the bed surface space it expands, the better the connection between the expanded part and the bed surface, and the more comfortable it is to use. In order to obtain a larger expansion space and a better user experience, the curvature of the bottom of the column needs to be as large as possible. However, the existing columns are usually tubular integrated structures made of iron or steel. Due to the properties of the material, it is difficult to increase the curvature of the bending process, so the expansion of the bed surface space is relatively small. In order to better expand the bed surface space and further improve the comfort, the column can be welded with sheet materials. The two sides of the column 2 are bent by sheet materials. The edges of the sheet materials on both sides are welded or connected as a whole through a docking plate. On the one hand, the column can be set in a tubular shape, and on the other hand, each sheet material can be easily bent differently, thereby improving the structural strength of the column, and the bottom of the column can be made into a larger curvature, so that the bed surface space can be better expanded and the comfort of use can be better improved.

[0040] Embodiment 4, as Fig.10 shown.

[0041] The bed guardrail structure described in this embodiment can also be Fig.10 As shown, the cross beam 1 is provided with an upward boss 13 between the support portion 21 of the column 2 and the beam plate of the column, and an upward vertical portion is provided on the adjacent side of the beam plate of the column and the boss to tightly fit with the inner side of the boss. When the guardrail is subjected to outward pressure, the column part is mainly clamped from the inside and outside by the support portion against the outer side of the cross beam and the vertical portion of the beam plate against the inner side of the boss. During the whole use process, the lock hook no longer bears the force alone, but plays a more limiting and auxiliary role. The horizontal portion of the beam plate and the cross beam, the vertical portion of the beam plate and the boss of the cross beam, and the support portion of the column and the outer side of the cross beam are all in surface contact, and the force-bearing area is greatly increased, thereby improving the connection strength.

[0042] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
