[0001] The utility model relates to the field of bedding, in particular to a bed backrest. Background Art

[0002] A backrest bed is a common bedroom bedding. The bed backrest at one end of the backrest bed only has a single backrest support function. Now many people like to read books or use computers in bed. To facilitate long-term reading and using computers, they will use a bedside table placed on the floor or a small table board placed on the bed. However, the bedside table takes up space when not in use. Especially in some small bedrooms, there is no extra space to place the table except for the aisle space; the small table board is not flat when placed on the legs and is very easy to be knocked over when the user turns over or raises the legs. When a laptop or a cup of hot water is placed on the small table board, it will damage the items or cause the risk of scalding. Content of the Utility Model

[0003] In order to solve the technical problems that the existing bedside table takes up space when not in use, and the small table board on the bed is not flat and easy to be knocked over, the utility model provides a bed backrest, which expands the use function. When needed, the bed backrest can be put down and used as a table board to place books, laptops or water cups. Users do not need to purchase a bedside table or a small table board on the bed additionally. And the bed backrest is not in the leg area, so it will not be accidentally knocked over when the user turns over or raises the legs, effectively preventing the risk of item breakage and scalding caused by the water cup being knocked over. When not in use, the bed backrest is retracted and used as a conventional bed back, without occupying the bedroom space.

[0004] The technical solution adopted by the utility model to solve the technical problems: A bed backrest, including a backrest body arranged on the surface of the bed screen, characterized in that the backrest body is composed of a movable upper backrest and a fixed lower backrest. The upper backrest can be rotated and laid flat relative to the lower backrest, and the top surface of the lower backrest after being laid flat can be used as a table top for placing items. The utility model changes the originally integral fixed backrest body into a split structure of upper and lower two sections. Among them, the lower backrest is fixed on the bed screen, and the upper backrest can be rotated and laid flat relative to the lower backrest. The top surface of the upper backrest after being laid flat is used as a table top to place laptops, books or cups, facilitating users to work, study and eat in bed; since the upper backrest is away from the user's leg area, the user will not touch the upper backrest when turning over or raising the legs, and will not knock over the table board and the items placed on it, avoiding the safety hazards of item breakage and scalding caused by the water cup being knocked over.

[0005] As a further improvement and supplement to the above technical solution, the utility model adopts the following technical measures: An inner table board movably connected with the upper backrest is arranged inside the upper backrest, and the inner table board can be movably extended from the upper backrest to place items. The upper backrest is also provided with an inner table board that can be movably extended, increasing the placement area of the bed backrest. Both the inner table board and the top surface of the upper backrest can be used as table tops for two people to use.

[0006] Preferably, the inner table board is slidably arranged on the upper backrest, and the inner table board can extend out of the upper backrest along the length direction of the upper backrest; or the inner table board is rotatably arranged on the upper backrest, and the inner table board can rotate and extend out along the plane where the upper backrest is located. The inner table board and the upper backrest can be slidably connected or rotatably connected, and both methods can enable the inner table board to extend out of the upper backrest movably.

[0007] Preferably, a flat groove is arranged in the upper backrest along its length direction, and the flat groove extends to form an opening at one end face of the upper backrest. The inner table board is placed in the flat groove and can extend out from the opening part. The upper backrest arranges the inner table board through the flat groove arranged along its length direction. When in use, a part of the inner table board extends out of the flat groove, and the remaining part stays in the flat groove to ensure that the extended and suspended part of the inner table board has sufficient rigidity to maintain stable load-bearing.

[0008] Preferably, a positioning structure is arranged between the flat groove and the inner table board to limit the extending length of the inner table board. The positioning structure includes a positioning part on the side of the inner table board and a limiting part on the inner wall of the flat groove. When the inner table board extends in place, the positioning part abuts against the limiting part. The function of the positioning structure is to limit the extending length of the inner table board out of the flat groove, thereby preventing the inner table board from coming out of the flat groove. The flat groove abuts against the positioning part on the side of the inner table board through the limiting part on its inner wall, so that a part of the inner table board always stays in the flat groove, achieving the effect of limiting the extending length of the inner table board.

[0009] Preferably, the inner table board is connected by a narrow section on the outer side and a wide section on the inner side that extend in the same direction. At least one protruding end that protrudes from the side of the narrow section is formed at the docking part of the narrow section and the wide section as the positioning part. The flat groove is connected by a narrow groove on the outer side and a wide groove on the inner side.

A reduced-diameter end that can abut against the protruding end is formed at the docking part of the narrow groove and the wide groove as the limiting part. The inner table board is composed of two board sections with different widths on the inside and outside. An outwardly protruding positioning part is formed at the docking part. Correspondingly, the flat groove is also composed of a narrow groove on the outer side and a wide groove on the inner side connected. A reduced-diameter limiting part is formed at the docking part. When the inner table board extends until the positioning part abuts against the limiting part, it is the maximum length for the inner table board to extend out of the flat groove, and the inner table board extends in place.

[0010] Preferably, the total lengths of the narrow groove and the wide groove are equivalent to the total lengths of the narrow section and the wide section, and the length of the narrow groove is shorter than the length of the wide groove, and the length of the narrow section is greater than the length of the wide section. The total lengths of the narrow groove and the wide groove are equivalent to the total lengths of the narrow section and the wide section, so that the inner table board can be retracted into the flat groove; at the same time, the length of the wide groove is greater than that of the narrow groove, and the length of the narrow section is greater than that of the wide section, so that the inner table board can have a certain pulling space in the flat groove and make telescopic movements relative to the flat groove.

[0011] Preferably, the upper backrest is rotatably connected to the lower backrest, or the upper backrest is rotatably connected to the headboard. The rotational connection of the upper backrest can be a movable connection with the lower backrest or a movable connection with the headboard. No matter which connection method is used, when the upper backrest rotates, it rotates relative to the fixed lower backrest.

DETAILED DESCRIPTION

[0019] The present invention will be further described below in conjunction with the accompanying drawings and specific implementation methods.

[0020] like Figure 1As shown in the figure, Embodiment 1 is a bed backrest, which includes a backrest body disposed on the surface of the bed screen 13. The backrest body is composed of a movable upper backrest 1 and a fixed lower backrest 2. The upper backrest 1 can be rotated and laid flat relative to the lower backrest 2. When the lower backrest 2 is laid flat, its top surface can be used as a tabletop 3 for placing items. Books, laptops or water cups can be placed on the tabletop. The bed screen 13 and the bed frame 14 in the figure are fixedly connected.

[0021] When you need to study or work in bed, rotate and lay flat the upper backrest. At this time, the back side of the upper backrest that originally faced the bed screen is used as a tabletop. When the upper backrest of the tabletop is away from the end of the bed near the feet, the upper backrest will not be overturned when raising the legs or turning over, thus avoiding damage to valuable items placed on the tabletop and scalding caused by the overturned water cup. Using the bed backrest as a table board is convenient and safe. When not in use, turn the upper backrest back to its original position against the bed screen. It can not only save the cost of buying a bedside table or a small table board for the head of the bed, but also eliminate the worry about storage.

[0022] As Figure 2 and Figure 3 As shown in the figure, Embodiment 2 is also a bed backrest. The difference from Embodiment 1 is that an inner table board 4 is provided inside the upper backrest 1 and is movably connected thereto. The inner table board 4 can be movably extended from the upper backrest 1 to place items. The movable extension of the inner table board can increase the placement area of the bed backrest. Both the inner table board and the top surface of the upper backrest can be used as tabletops for two people to use, with one person using the inner table board and the other using the top surface of the upper backrest respectively.

[0023] Furthermore, the inner table board 4 is slidably disposed on the upper backrest 1, and the inner table board 4 can extend out of the upper backrest 1 along the length direction of the upper backrest 1; a flat groove 5 is provided inside the upper backrest 1 along its length direction, and the flat groove 5 extends to one end face of the upper backrest 1 to form an opening 6. The inner table board 4 is placed in the flat groove 5 and can partially extend out from the opening 6. In addition, the inner table board 4 can also be rotatably disposed on the upper backrest 1, and the inner table board 4 can be rotatably extended along the plane where the upper backrest 1 is located. The upper backrest is provided with a flat groove along its length direction to accommodate the inner table board. When in use, the inner table board is partially pulled out from the flat groove, and the remaining part remains in the flat groove to ensure that the suspended extended part of the inner table board has sufficient rigidity to stably support heavy objects such as laptops, books, water containers and eating utensils.

[0024] Further, a positioning structure is provided between the flat groove 5 and the inner table board 4 to limit the extending length of the inner table board 4. The positioning structure includes a positioning portion 7 on the side of the inner table board 4 and a limiting portion 8 on the inner wall of the flat groove 5. When the inner table board 4 extends in place, the positioning portion 7 abuts against the limiting portion 8. The inner table board 4 is formed by connecting a narrow section 4-1 on the outer side and a wide section 4-2 on the inner side that extend in the same direction. At least one protruding end that protrudes from the side of the narrow section 4-1 is formed at the docking portion of the narrow section 4-1 and the wide section 4-2 as the positioning portion 7. The flat groove 5 is formed by connecting a narrow groove 5-1 on the outer side and a wide groove 5-2 on the inner side. The narrow groove 5-1 and the wide groove 5-2 respectively match the cross-sectional shapes of the narrow section 4-1 and the wide section 4-2. A reduced-diameter end that can abut against the protruding end is formed at the docking portion of the narrow groove 5-1 and the wide groove 5-2 as the limiting portion 8. In this embodiment, the total lengths of the narrow groove 5-1 and the wide groove 5-2 are equivalent to the total lengths of the narrow section 4-1 and the wide section 4-2, and the length of the narrow groove 5-1 is shorter than the length of the wide groove 5-2, and the length of the narrow section 4-1 is greater than the length of the wide section 4-2.

[0025] The positioning structure limits the length of the inner table board extending out of the flat groove during use, preventing the inner table board from completely coming out of the flat groove. When the limiting portion on the inner wall of the flat groove abuts against the positioning portion on the side of the inner table board, the inner table board extends in place and always has a part remaining in the flat groove. A reduced-diameter end that can abut against the protruding end is formed at the docking portion of the narrow groove and the wide groove as the limiting portion. In this embodiment, the inner table board is composed of two inner and outer board sections with different widths and forms a protruding positioning portion at the docking portion. Correspondingly, the flat groove is also composed of a narrow groove on the outer side and a wide groove on the inner side and forms a reduced-diameter limiting portion at the docking portion. When the inner table board extends until the positioning portion abuts against the limiting portion, it is the maximum length of the inner table board extending out of the flat groove, and at this time, the inner table board extends in place. By setting the total lengths of the narrow groove and the wide groove to be equivalent to the total lengths of the narrow section and the wide section, the inner table board can completely retract into the flat groove; at the same time, the length of the wide groove is greater than that of the narrow groove, and the length of the narrow section is greater than that of the wide section, so that the inner table board has a certain space for moving and pulling in the flat groove to expand and contract relative to the flat groove.

[0026] Further, the upper backrest 1 is rotatably connected to the lower backrest 2. In addition, the upper backrest 1 can also be rotatably connected to the headboard 13. In this embodiment, the first type of connection between the upper backrest and the lower backrest is preferably selected. The upper backrest 1 and the lower backrest 2 are connected by a hinged plug-in plate assembly. The plug-in plate assembly includes an upper plate 9 and a lower plate 10 that are respectively inserted and fixed to the upper backrest 1 and the lower backrest 2. The upper backrest 1 and the lower backrest 2 are respectively provided with an upper plug-in slot 11 and a lower plug-in slot 12 that match the upper plate 9 and the lower plate 10. The upper backrest is rotatably connected to the lower backrest through a hinged plug-in plate assembly. The plug-in plate assembly includes an upper plate and a lower plate that are hinged to each other. The upper plate is hidden and fixed in the upper backrest through the upper plug-in slot, and the lower plate is hidden and fixed in the lower backrest through the lower plug-in slot.

[0027] Further, the upper backrest 1 includes an upper backrest cover 1-1 and an upper backrest plate 1-2 that fits thereto. The outer surface of the upper backrest plate 1-2 forms the tabletop 3. The lower backrest 2 includes a lower backrest cover 2-1 and a lower backrest plate 2-2 that fits thereto. Both the upper backrest cover 1-1 and the lower backrest cover 2-1 are made by wrapping a sponge around a skeleton. The upper slot 11 and the lower slot 12 are respectively arranged on the upper backrest cover 1-1 and the lower backrest cover 2-1. Both the upper backrest and the lower backrest include a soft backrest cover and a fitting rigid backrest plate. The soft backrest cover is made by wrapping a sponge around an internal skeleton, improving the comfort when used as a bed backrest. The tabletop of the upper backrest is the outer surface of the rigid upper backrest plate. The upper slot and the lower slot are respectively arranged on the upper and lower backrest covers, and the corresponding upper plate and lower plate are fixedly hinged.
