Description

Technical Field

[0001] The utility model belongs to the field of furniture, and in particular relates to a folding bed frame and bedding. Background Art

[0002] Traditional bed frames are made by splicing multiple support plates, bedside frames and bed boards (or reinforcing beams), where the support plates and bedside frames are fixedly connected. The structure is bulky, and when the bed frame needs to be moved or recovered, it usually requires the cooperation of multiple people. In contemporary society, the number of one-person households is gradually increasing, and fixed bed frames are extremely unfriendly to such users.

[0003] There are many kinds of folding bed frames on the market, which are usually composed of multiple metal tubes that can rotate relative to each other. In order to achieve relative rotation between the metal tubes, the folding bed frame usually needs to be connected with a large number of screws and pins, which may easily cause the screws to loosen or fall off, causing inconvenience in use and even affecting the stability and safety of the folding bed frame.

DETAILED DESCRIPTION

[0032] The technical solution of the present invention is clearly and completely described below in conjunction with the accompanying drawings of the present invention; it is obvious that the embodiment described above is only one implementation method of the present invention, and all other embodiments obtained by ordinary technicians in this field without making creative work based on the following embodiments belong to the protection scope of the present invention.

[0033] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected" to another element, it may be directly connected to the other element or there may be a central element at the same time. In the present utility model, the terms "upper", "lower", "bottom", "rear", "side", etc. indicate that the orientation or position relationship is based on the orientation or position relationship shown in the drawings, which is only for the purpose of simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present utility model. In this embodiment, "lower" refers to the direction close to the ground or other supporting surface after the elements are unfolded and spliced ​​to form a folding bed frame. "Horizontal" in this application refers to the arrangement along the width direction of the folding bed frame, and "longitudinal" refers to the arrangement along the length direction of the folding bed frame, but here "horizontal" and "longitudinal" or "width direction" and "length direction" are only two mutually perpendicular directions without any other restrictions on the folding bed frame. For example, the size of the folding bed frame along its length direction may be greater than, equal to or less than its size in the width direction.

[0034] In the following embodiments, the sleeve part is made of hard plastic, which has good connection stability and certain elasticity. When the sleeve part and the bed frame column rotate relative to each other, the sleeve part undergoes elastic deformation and fits tightly with the bed frame column.

[0035] Example 1

[0036] like Figure 1 and Figure 2 As shown, the folding bed frame includes two oppositely arranged transverse supports 1, two parallel longitudinal support beams 2, an intermediate support 3, a plurality of parallel transverse reinforcement beams 4 and a plurality of parallel longitudinal reinforcement beams 5, the two transverse supports 1 are respectively located on both sides of the longitudinal direction of the folding bed frame and extend along the transverse direction of the folding bed frame, and the two ends of the longitudinal support beam 2 are respectively connected to the ends of the two transverse supports 1.

[0037] Among them, Figure 3 As shown, the transverse support 1 includes a transverse support beam 11 and a bed frame column 12 perpendicular to the transverse support beam 11. The bed frame column 12 is fixedly connected to the transverse support beam 11 in the middle section, and the cross section of the upper end of the bed frame column 12 is an ellipse;

[0038] Back to Figure 2 The longitudinal support beam 2 includes two main sections 21 and a U-shaped connecting piece 22. One end of the two main sections 21 is rotatably connected to the U-shaped connecting piece 22, so that the main section 21 can rotate in the horizontal direction with the connection between the main section 21 and the U-shaped connecting piece 22 as the axis, thereby opening or folding the longitudinal support beam 2. Furthermore, the openings of the U-shaped connecting pieces 22 of the two longitudinal support beams 2 are arranged opposite to each other (or in other words, the direction of the opening is away from the folding bed frame), so that the longitudinal support beam 2 folds toward the inside of the folding bed frame when folded. In the process of changing from the open state to the folded state, the angle between the two main sections 21 decreases from 180° to 0°, and the angle between the main section 21 and the transverse support 1 decreases from 90° to 0°. The folding of the longitudinal support beam 2 drives the two transverse supports 1 to approach each other, thereby realizing the folding of the transverse support 1 and the longitudinal support beam 2 in the folding bed frame.

[0039] In the present application, the transverse support 1 is sleeved with the longitudinal support beam 2. Specifically, the end of the main section 21 of the longitudinal support beam 2 away from the U-shaped connecting piece 22 is provided with a sleeve portion 221 that penetrates in the height direction, and the cross section of the inner cavity of the sleeve portion 221 is elliptical and the long axis length of the cross section of the bed frame column 12 is greater than the short axis length of the cross section of the inner cavity. The two ends of the longitudinal support beam 2 are respectively sleeved with the upper end of the bed frame column 12 of a transverse support 1 through the sleeve portion 221 so that the longitudinal support beam 2 can move in the height direction along the upper end of the bed frame column 12 or rotate in the horizontal direction with the bed frame column 12 as the axis.

[0040] The cross-section of the inner cavity of the sleeve portion 221 and the outer cross-section of the bed frame column 12 are mutually matching ellipses. When the longitudinal support beam 2 is in a folded state, the longitudinal support beam 2 is roughly parallel to the transverse support beam 11, and the long axes of the two ellipses are in the same direction. When the longitudinal support beam 2 is in an open state, the longitudinal support beam 2 is perpendicular to the transverse support beam 11, and the direction of the long axis of the cross-section of the bed frame column 12 is consistent with the direction of the short axis of the cross-section of the inner cavity of the sleeve portion 221. Since the length of the short axis of the cross-section of the inner cavity of the sleeve portion 221 is smaller than the length of the long axis of the cross-section of the bed frame column 12, the sleeve portion 221 undergoes elastic deformation under the extrusion of the bed frame column 12, so that the sleeve portion 221 is clamped with the bed frame column 12.

[0041] If the two longitudinal support beams 2 are located at the same height, it is obvious that the two longitudinal support beams 2 will interfere with each other during the folding process, resulting in failure to complete the folding. In the present application, the transverse support 1 is connected to the longitudinal support beam 2, and the longitudinal support beam 2 can move in the height direction along the upper end of the bed frame column 12. Figure 2 As shown, the two longitudinal support beams 2 are staggered in the height direction to avoid mutual interference.

[0042] Furthermore, if Figure 4The lower end of the sleeve portion 221 is formed with a bracket clamping interface 2111 which opens downwards. The bracket clamping interface 2111 can be engaged with the transverse support beam 11. When the main body section 21 and the transverse support beam 11 are perpendicular to each other, the bracket clamping interface 2111 is directly opposite to the transverse support beam 11. By pressing the longitudinal support beam 2 downward, the bracket clamping interface 2111 is engaged with the transverse support beam 11, which limits the horizontal rotation of the longitudinal support beam 2 relative to the bed frame column 12, so that the folding bed frame can be stably kept in the open state.

[0043] The U-shaped connecting piece 22 is also provided with a support foot slot 221 opening downward. The intermediate bracket 3 includes two support feet 31 and a reinforcing tube 32. The two ends of the reinforcing tube 32 are respectively connected to the middle part of a support foot 31, and the support foot slot 221 is plugged into the upper end of the support foot 31.

[0044] The two ends of the transverse reinforcement beam 4 are respectively connected to the longitudinal support beam 2 through a clamping structure. Specifically, the clamping structure includes a clamping mother part arranged on the inner surface of the longitudinal support beam 2 and a clamping sub-part 41 arranged at both ends of the transverse support beam 11. The clamping sub-part 41 cooperates with the clamping mother part to achieve clamping.

[0045] The two ends of the longitudinal reinforcement beam 5 are respectively plugged with the transverse support beam 11 or the transverse reinforcement beam 4 through a plug-in structure. Specifically, the plug-in structure includes downward plug-ins 51 arranged at both ends of the longitudinal reinforcement beam 5 and slots 111 arranged on the transverse support beam 11 and the transverse reinforcement beam 4. The slots 111 and the plug-ins 51 cooperate to plug in to achieve the connection between the longitudinal reinforcement beam 5 and the transverse support beam 11 and / or the transverse reinforcement beam 4.

[0046] In addition, the folding bed frame of the present embodiment further comprises a bed head 6, which has two bed head posts 61, the width between the two bed head posts 61 is the same as the width between the two bed frame posts 12 of the transverse support 1, the upper end of the bed frame post 12 has a post slot 62 downward in the height direction, and the bed frame post 12 and the bed head post 61 are plugged in through the post slot 62. The outer peripheral cross section of the lower end of the bed head post 61 is an ellipse that matches the inner cavity of the sleeve 221, and the sleeve 221 can realize rotation and up and down movement at the connection between the bed head post 61 and the bed frame post 12.

[0047] Example 2

[0048] The difference between Example 2 and Example 1 is that the structure of the sleeve portion 221 is different, the column slot 62 is arranged at the lower end of the headboard column 61, and the bed frame column 12 is provided with a positioning rivet 121 at its upper end.

[0049] Specifically, Figure 5 As shown, the column slot 62 on the bedside column 61 is arranged upward from the bottom surface of the bedside column 61 in the height direction, as shown in FIG. Figure 6As shown, the bed frame column 12 is provided with a positioning rivet 121 at its upper end, and the column slot 62 is provided with a positioning slot 621 at a corresponding position on its side wall. When the bed frame column 12 is plugged into the headboard column 61 , the positioning rivet 121 is engaged with the positioning slot 621 .

[0050] Since the length of the positioning rivet 121 protruding from the outer wall of the upper end is greater than the thickness of the column slot 62, when the positioning rivet 121 is engaged with the positioning snap-in 621, part of the positioning rivet 121 will still be exposed from the positioning snap-in 621 (not shown in the figure). Therefore, in this embodiment, a positioning groove 2112 is provided on the inner wall of the sleeve part 221 for clamping the end of the positioning rivet 121 away from the slot 111. The positioning rivet 121 can be displaced horizontally and in height relative to the sleeve part 221 along the positioning groove 2112.

[0051] Figure 7 The shape of the positioning groove 2112 in this embodiment is shown. The starting end of the positioning groove 2112 is located on the top surface of the sleeve part 221. The positioning groove 2112 extends downward from the starting end and then extends on the horizontal plane along the inner wall of the sleeve part 221. In the folded state, the positioning rivet 121 is located at the end of the positioning groove 2112 away from the starting end. Then, during the opening process, the positioning rivet 121 moves horizontally along the positioning groove 2112 equivalent to 1 / 4 of the inner circumference of the sleeve part 221. After the folding bed frame is fully opened, the longitudinal support beam 2 is pressed downward, and the positioning rivet 121 moves upward relative to the sleeve part 221 along the positioning groove 2112. Finally, the bottom of the sleeve part 221 abuts against the top surface of the transverse support beam 11. The positioning rivet 121 is located at the starting end of the positioning groove 2112. The positioning rivet 121 and the positioning groove 2112 cooperate to limit the horizontal rotation of the longitudinal support beam 2 relative to the bed frame column 12, so that the folding bed frame can be stably maintained in the open state.

[0052] Example 3

[0053] The difference between Example 3 and Example 2 is that the structure of the positioning groove 2112 is different.

[0054] Figure 8The shape of the positioning groove 2112 in this embodiment is shown. The starting end of the positioning groove 2112 is located on the top surface of the sleeve part 221, and then extends obliquely downward along the inner wall of the sleeve part 221. In the folded state, the positioning rivet 121 is located at the end of the positioning groove 2112 away from the starting end. Then, during the opening process, the positioning rivet 121 rotates and moves upward along the positioning groove 2112 relative to the sleeve part 221. Finally, the bottom of the sleeve part 221 abuts against the top surface of the transverse support beam 11, and the positioning rivet 121 is located at the starting end of the positioning groove 2112. The positioning rivet 121 and the positioning groove 2112 cooperate to limit the horizontal rotation of the longitudinal support beam 2 relative to the bed frame column 12, so that the folding bed frame can be firmly maintained in the open state.
