Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

In order to make the technical field of the present invention better understand, the present invention will be described in detail with reference to the accompanying drawings and the detailed description.

Referring to fig. 1 to 5, fig. 1 is a schematic view of an everting folding bracket according to an embodiment of the present invention, fig. 2 is a partially enlarged view of a hinge limiting member in fig. 1, fig. 3 is a partially enlarged view of a portion a in fig. 1, fig. 4 is a partially enlarged view of a portion B in fig. 1, and fig. 5 is a partially enlarged view of a portion C in fig. 1.

The everting folding bracket provided by the utility model comprises side pipe components and foot pipe components, wherein a pair of side pipe components are oppositely arranged in parallel and are used for connecting a fixed bed surface; the plurality of groups of foot pipe assemblies are arranged below the side pipe assemblies in parallel, and the two ends of each foot pipe assembly are respectively connected with a pair of side pipe assemblies to complete the support of the side pipe assemblies. In order to reduce the volume after folding, the pin tube assembly is provided with a hinged limiting piece 3 for turning and folding along the midpoint thereof, and the bracket is folded in the width direction through the hinged limiting piece 3; the side tube assembly comprises a plurality of side tubes 2 which are arranged in sequence, the adjacent side tubes 2 are connected through the hinge pieces to realize the folding of the side tube assembly in the length direction, and the folding mode is adopted to ensure that the volume of the everting folding type support is reduced by half compared with the volume of the traditional folding bed support after being folded; and the everting folding mode of the side tube component enables the overturning direction of the side tube component to be opposite to the traction force direction received when the bed surface bears the weight, so that the bed surface is prevented from descending due to the fact that the side tube component is automatically turned inwards, and the stability of the support is improved.

The present invention will be described in more detail with reference to the accompanying drawings and specific embodiments.

The utility model provides an in one embodiment, the setting of foot pipe assembly and articulated locating part 3 is as shown in fig. 1 and fig. 2, and foot pipe assembly includes the foot pipe 1 of the L type of a pair of relative setting, and the foot pipe 1 of L type is articulated and spacing through articulated locating part 3 realization, and the corner department of foot pipe 1 with fillet rounding off, avoids folding back closed angle outstanding, portable not.

The pair of foot tubes 1 are hinged through longer sides, and the shorter sides extend in the same direction and are respectively connected with the side tube assemblies to support the side tube assemblies to a preset height. The setting of articulated locating part 3 makes foot pipe 1 can realize the upset fifty percent discount and only can take place the upset dorsad, here the upset dorsad specifically indicate that the shorter side of foot pipe 1 is rotatory with the direction that deviates from each other, also connect the both sides pipe assembly along the direction upset that deviates from each other of the shorter side of foot pipe 1, when the upset, the interval between both sides pipe 2 can crescent, reaches to wait for the most and reduce along with the increase of system rotation angle, and the folding is accomplished to the longer limit coincidence of foot pipe 1.

When the support is completely unfolded, the hinged limiting parts 3 limit the two pin pipes 1, and the side pipe assemblies are prevented from being continuously folded inwards.

The side pipe assembly is formed by hinging a plurality of sections of side pipes 2, and the adjacent side pipes 2 are hinged through hinging pieces so as to realize the folding of the side pipe assembly along the length direction of the side pipe assembly. The number, the length and the arrangement position of the hinge pieces of the side tubes 2 of the pair of side tube assemblies are completely the same, so that the pair of side tube assemblies can be folded synchronously along the length direction after being folded and overlapped in an overturning way.

With further reference to fig. 3 to 5, the connection of the hinge member and the side tube 2 can be arranged with reference to the drawings. The hinged parts are divided into end hinged parts 4 and middle hinged parts 5 according to different arrangement positions, and as the name suggests, the end hinged parts 4 are arranged at two ends of the side pipe assembly and are used for connecting the side pipe 2 at the most end part; a middle hinge 5 is provided in the middle between the side tubes 2 for connecting adjacent side tubes 2.

No matter the end part articulated piece 4 or the middle part articulated side is fixedly connected with the end part of the shorter side of the L-shaped foot tube 1 through the bottom part, and is articulated with the side tube 2 through an articulated groove arranged on the side part, so that the rotation of the side tube 2 relative to the articulated piece is realized. The bottom of end articulated elements 4 and middle articulated elements 5 all is equipped with the spliced eye that supplies the tip grafting of foot pipe 1, and the rigid coupling is realized through locating pin or set screw behind the spliced eye to foot pipe 1 grafting, avoids the relative articulated elements of foot pipe 1 to drop. The hinge groove is seted up to one side of the lateral part of end articulated elements 4, and side pipe 2 passes through the articulated shaft and connects in the hinge groove, and the hinge groove is all set up to the both sides of the lateral part of middle part articulated elements 5, and the hinge groove of both sides is 180 and also extends in opposite directions to make the coaxial extension of adjacent side pipe 2.

The outer wall in hinge groove forms the spacing shell 6 of C-shaped or U-shaped, and the spacing shell 6 of U-shaped forms spacingly to side pipe 2 for side pipe 2 can only be along the one-way upset folding of notch direction. Since the thickness of the stent of the folded portion is gradually increased when the side tube 2 is folded in the length direction of the side tube assembly, the folding is conveniently accomplished. The length of the middle hinge member 5 is gradually increased along the direction from both ends of the side pipe assembly to the middle portion, that is, the closer the distance between the adjacent side pipes 2 in the middle of the side pipe assembly is, the larger the distance between the hinge shafts of the two hinge side pipes 2 corresponding to the middle hinge member 5 is.

Above-mentioned foldable support turns up makes foot pipe 1 earlier use articulated locating part 3 to lift as the center when needs are folding, and the interval of side pipe subassembly increases earlier and reduces afterwards, treats that the notch direction of the spacing shell 6 of the U-shaped of the articulated elements of the side pipe subassembly department of both sides overturns to when upwards simultaneously, and the length direction along the side pipe subassembly uses the articulated elements to fold as the folding point, carries out the fifty percent discount with foot pipe subassembly with articulated locating part 3 as the center at last. When distraction is required, the deployment is done in the reverse order.

The utility model provides a folding bed comprising the eversion folding bracket, which also comprises a bed surface connected between a pair of side tube components of the eversion folding bracket, wherein the bed surface adopts cloth cover or cloth strips as required; other parts of the folding bed can be referred to the prior art and are not unfolded herein.

It is noted that, in this specification, relational terms such as first and second, and the like are used solely to distinguish one entity from another entity without necessarily requiring or implying any actual such relationship or order between such entities.

The folding bed and the everting folding bracket thereof provided by the utility model are introduced in detail. The principles and embodiments of the present invention have been explained herein using specific examples, and the above descriptions of the embodiments are only used to help understand the method and its core ideas of the present invention.
