Description

Technical Field

[0001] The utility model relates to the field of bedding, and particularly to a bed frame. Background Art

[0002] The existing bed frame includes a base and a backrest arranged at the front edge of the base. The rear wall of the backrest faces the base, which not only serves as a support for the user to lean on but also has a decorative function. Since the leaning surface faces backward and provides front-to-back support for the leaning user, the user is prone to slipping sideways due to the lack of lateral support, affecting the use experience. Content of the Utility Model

[0003] In order to solve the deficiencies of the prior art, the utility model provides a bed frame with an armrest whose posture can be adjusted on the backrest. The armrest in the supporting state can provide lateral support for the user, improving the comfort of leaning, and the armrest can also be switched to the storage state to obtain a flat leaning surface, enhancing the aesthetics.

[0004] The utility model is realized in the following way: A bed frame includes a base and a backrest with a back panel. A swingable armrest is provided on the leaning surface of the backrest, and the armrest can be deformed and switched between a storage state where it fits with the back panel and a supporting state where it is separated from the back panel. By setting an armrest with adjustable posture on the backrest, which can be switched between the storage state and the supporting state, the armrest in the supporting state can provide lateral support for the user, improving the comfort of leaning, and the armrest can also be switched to the storage state to obtain a flat leaning surface, enhancing the aesthetics. The back panel plays a role in supporting and shaping the backrest, ensuring that the backrest will not collapse and deform when leaned on.

[0005] Preferably, when the armrest is switched to the storage state, the backrest and the armrest are combined to form a leaning surface. The armrest fits with the back panel to form a flat leaning surface, so that the armrest is hidden in the backrest and has the same contour as the traditional backrest.

[0006] Preferably, when the armrest is switched to the supporting state, the armrest is partially separated from the back panel and forms an upwardly exposed supporting surface. When the armrest is in the supporting state, at least part of the armrest is separated from the back panel and exposed outside the backrest, so that the top surface of a partial section of the armrest forms an upwardly exposed supporting surface, and the user can obtain lateral support by leaning on the supporting surface, improving the comfort of leaning.

[0007] Preferably, there are two armrests, which are symmetrically arranged on both sides of the backrest, which not only facilitates the user to obtain corresponding lateral support through the corresponding armrest according to needs, but also improves the aesthetics of the backrest by symmetrically arranging the armrests.

[0008] Preferably, the armrest includes a fixed portion connected to the backboard and a movable portion mounted on the fixed portion through a hinge, a storage position is set on the backrest, and the movable portion can swing back and forth along a preset path under the guidance of the hinge, and the armrest switches to the storage state when the movable portion swings to the storage position. The fixed portion is fixed to the backboard, and the movable portion is swingably mounted on the fixed portion, ensuring that the movable portion can swing back and forth along a preset path in a preset posture, thereby realizing the accurate switching of the armrest between the storage state and the supporting state, which is convenient for users to switch and use.

[0009] Preferably, the hinge is installed on the side edge of the fixed part with the axis vertically arranged, the storage station is arranged on the side of the fixed part, and the movable part can be swung horizontally to the storage station. The movable part is connected to the fixed part by a hinge, which is convenient for assembly and can ensure that the movable part swings along a preset path, ensuring that the armrest swings horizontally and switches accurately between the storage state and the supporting state. Since the axis of the hinge is arranged vertically, the armrest can swing freely in the horizontal plane and adjust the angle between the movable part and the fixed part to meet the use requirements. When the movable part is in the storage position, it will fit tightly with the back panel, thereby transmitting the leaning force from the user to the back panel.

[0010] Preferably, the hinge is installed on the top edge of the fixed part with the axis horizontally arranged, the storage station is arranged above the fixed part, and the movable part can swing vertically to the storage station. The armrest swings vertically and can switch between the storage state and the supporting state. The armrest can swing vertically with the top edge of the fixed part as the center, and the armrest in the supporting state can provide effective support for the user.

[0011] Preferably, the angle between the movable part and the fixed part is adjustable and positionable. The angle between the movable part and the fixed part is adjustable, which not only ensures that the side wall of the armrest can match and fit the user, improving the comfort of leaning, but also effectively adjusts the area of ​​the supporting surface, thereby meeting the user's leaning needs. The hinge can not only guide the swing of the movable part, but also position the swinging movable part, preventing the armrest from shifting when the user leans on it, and providing reliable lateral support for the user.

[0012] Preferably, at least two separate hinges are provided between the fixed portion and the movable portion, so that the movable portion can swing along a preset path in a preset posture. By increasing the number of hinges, it is ensured that the movable portion can swing in a preset posture, and the movable portion is prevented from deflecting or shifting inconsistent with the preset swing path due to force, thereby providing reliable support for the user.

[0013] Preferably, the backrest is provided with an embedding groove, which forms the storage station. The embedding groove is used to hide the armrest, and the groove cavity contour of the embedding groove matches the contour of the armrest, which not only ensures the flatness of the leaning surface, but also provides a resistance limit for the armrest in the storage state. When the armrest is switched to the storage state, it can be embedded in the embedding groove to achieve hidden storage.

[0014] Preferably, the armrest is completely wrapped by an outer cover made of elastic fabric. When the armrest deforms, the outer cover keeps in close contact with the surface of the armrest through its own stretching and shrinking. The outer cover plays a role in protecting and covering the armrest, effectively improving the aesthetics. The area of the side wall of the armrest changes due to the swinging deformation between the storage state and the supporting state. The outer cover eliminates the influence of the change in the side wall area of the armrest on the fitting property through its own deformation, ensuring that the outer cover is always in close contact with the surface of the armrest.

[0015] Preferably, an elastic comfort layer is filled between the outer cover and the armrest. The elastic comfort layer has elastic deformation performance, which can not only improve the comfort of leaning on the armrest, but also appropriately reduce the requirement for the stretching amplitude of the outer cover caused by the deformation of the armrest, preventing local wrinkles or excessive stretching of the outer cover.

[0016] The beneficial effects of the present utility model are as follows: An armrest with adjustable posture is provided on the backrest. The armrest can be switched between the storage state and the supporting state, which can not only use the armrest in the supporting state to provide lateral support for the user and improve the comfort of leaning, but also switch the armrest to the storage state to obtain a flat leaning surface and improve the aesthetics.

[0024] The following further illustrates the substantial features of the present utility model in conjunction with the accompanying drawings of the specification and the specific embodiments.

[0025] As shown in Figure 1 and 2A bed frame as shown includes a base 1 and a backrest 2 with a back panel. An adjustable armrest 3 is provided on the leaning surface of the backrest 2, and the armrest 3 can be deformed and switched between a storage state where it fits against the back panel and a supporting state where it is separated from the back panel. By providing an armrest 3 with adjustable posture on the backrest 2, and the armrest 3 can be switched between the storage state and the supporting state. It can not only use the armrest 3 in the supporting state to provide lateral support for the user and improve the leaning comfort, but also switch the armrest 3 to the storage state to obtain a flat leaning surface and improve the aesthetics.

[0026] In actual operation, the backrest 2 includes a back panel, and the armrest 3 includes a fixed part 5 connected to the back panel and a movable part 7 installed on the fixed part 5 through a hinge 6. The movable part 7 can reciprocally swing along a preset path under the guidance of the hinge 6, so that the armrest 3 can be switched between the storage state and the supporting state. One end of the hinge 6 is connected to the fixed part 5, and the other end is connected to the movable part 7, which not only ensures that the movable part 7 can be firmly installed on the fixed part 5, but also ensures that the movable part 7 can swing and switch between different states along the preset path in a preset posture under the guidance of the hinge 6.

[0027] When the armrest 3 is in the storage state (as Figure 4 shown), the armrest 3 is completely hidden in the storage position, and the side wall of the armrest 3 facing the base 1 and the side wall of the backrest 2 facing the base 1 are smoothly connected to each other, and the backrest 2 obtains a flat leaning surface by hiding the armrest 3.

[0028] When the armrest 3 is in the supporting state (as Figure 5 shown), at least part of the armrest 3 is exposed outside the storage position, and the area where the top surface of the armrest 3 is exposed outside the storage position forms an upwardly open supporting surface to provide lateral support for the user, thereby improving the leaning comfort.

[0029] In actual operation, storage positions are provided on both sides of the backrest 2, and there are two armrests 3 which are symmetrically arranged on both sides of the backrest 2. The armrest 3 is switched to the storage state and completely hidden in the storage positions, so that the backrest 2 and the armrests 3 are combined to form a flat leaning surface. The backrest forms the storage positions by opening grooves 4, and the armrest 3 can be deformed and switched between the storage state hidden in the backrest 2 and the supporting state exposed outside the backrest 2. The cavity contour of the groove 4 matches the contour of the armrest 3. When the armrest 3 is switched to the storage state, the groove wall of the groove 4 can play a role of resisting and limiting the armrest 3, preventing the armrest 3 from being embedded in the groove 4 due to excessive force and ensuring that the leaning surface remains flat.

[0030] In actual operation, the hinge 6 is installed on the side edge of the fixed part 5 with its axis vertically placed. The slot 4 is arranged on the side of the fixed part 5, and the movable part 7 can swing reciprocally horizontally. The fixed part 5 is arranged in the middle of the backrest 2, and the slot 4 is arranged on the side of the backrest 2. The fixed part 5 and the corresponding slot 4 are arranged adjacent to each other, so that the movable part 7 connected to the fixed part 5 can swing smoothly and be hidden in the slot 4.

[0031] In actual operation, the included angle between the movable part 7 and the fixed part 5 is adjustable and positionable. The movable part 7 and the fixed part 5 are connected by the hinge 6 (as Figure 3 shown). The opening and closing angle between the two end parts of the hinge 6 is adjustable and positionable. The user adjusts and positions the angle between the movable part 7 and the fixed part 5 according to the usage requirements, which not only ensures that the position and area of the supporting surface meet the usage requirements, but also effectively prevents the movable part 7 from deflecting due to lateral extrusion.

[0032] Specifically, when the armrest 3 is switched to the supporting state, the movable part 7 and the fixed part 5 are bent with respect to each other. When the included angle between the movable part 7 and the fixed part 5 is 90°, the movable part 7 is perpendicular to the leaning surface, and the supporting surface has the largest area. When the included angle between the movable part 7 and the fixed part 5 is between 90° and 180°, the area of the supporting surface will decrease as the included angle increases, and the side wall contour of the armrest 3 will be flatter. When the armrest 3 is switched to the storage state, the included angle between the movable part 7 and the fixed part 5 is 180°, and the movable part 7 and the fixed part 5 are in a straight state with respect to each other.

[0033] In actual operation, at least two separate hinges 6 are provided between the fixed part 5 and the movable part 7, so that the movable part 7 swings along a preset path in a preset posture. The hinges 6 are arranged at intervals along the connection between the fixed part 5 and the movable part 7, ensuring that the movable part 7 swings, switches and positions along the preset path, and ensuring that the user can obtain effective support. The hinge 6 has a multi-stage structure, and each stage has the same adjustment range. Specifically, the hinge 6 has 7 stages, and each stage has the same adjustment range, so that the included angle between the fixed part 5 and the movable part 7 is adjustable. Preferably, the hinge adopts a stepless adjustment method, which should also be regarded as a specific embodiment of the present invention.

[0034] In actual operation, the armrest 3 is completely wrapped by the outer cover 8. The outer cover 8 is made of an elastic fabric. When the armrest 3 deforms, the outer cover 8 keeps in contact with the surface of the armrest 3 through its own expansion and contraction. An elastic comfort layer 9 is filled between the outer cover 8 and the armrest 3. The elastic comfort layer 9 is in two layers and clamps the armrest 3 (as Figure 6As shown). Both the outer cover 8 and the elastic comfort layer 9 have elastic reset features, enabling the outer cover 8 and the elastic comfort layer 9 to cooperate with each other and offset the influence of the surface area change generated by the armrest 3 when switching between different states, ensuring that the outer cover 8 can always closely fit on the surface of the armrest 3. This not only prevents the outer cover 8 from wrinkling due to the reduction of the surface area of the corresponding area of the armrest 3, but also prevents the outer cover 8 from being damaged by excessive stretching due to the increase of the surface area of the corresponding area of the armrest 3, effectively extending the service life of the outer cover 8 and the elastic comfort layer 9. The elastic comfort layer 9 is made of sponge material, preferably ultra-soft sponge, which not only ensures a large deformation space reserved in the elastic comfort layer 9, effectively increasing its elastic deformation range, but also ensures that the elastic comfort layer 9 can restore its original shape in a timely manner without external force, ensuring that the outer cover 8 maintains a plump state.

[0035] It can be understood that the groove 4 can also be provided above the fixed part 5, and the hinge 6 is installed on the top edge of the fixed part 5 with its axis horizontally placed, so that the movable part 7 can swing and switch between the supporting position where it abuts against the fixed part 5 in the front-rear direction and the storage state hidden in the groove 4 above the fixed part 5, which should also be regarded as a specific embodiment of the present invention.

[0036] It can be understood that the back plate can be a plate with good structural strength, or a bracket with good structural strength, both of which should be regarded as specific embodiments of the present invention.
