Description

Folding bed that can effectively reduce the volume

The invention relates to a folding bed that can effectively reduce the volume of materials, especially a folding bed technology that can make the bed frame assembly and the bed board assembly have both horizontal and vertical folding functions by setting the functions of vertical and horizontal folding.

In order to solve the shortcomings of the conventional bed frame device due to the lack of a folding mechanism, the volume is too large, the handling is laborious and inconvenient, a large storage space or freight space is required, and the freight cost is increased. Therefore, the foldable bed has become a bed. The technical means adopted by the practitioners in the technical field to solve the above-mentioned deficiencies. The current known folding bed frame is composed of two main support frames that are pivotally connected to each other and can be folded relative to each other along the longitudinal direction of the folding bed frame. The mattress is used to form the basic structure of the folding bed. When storing or transporting, the two mutually pivoted main support frames can be folded in half with each other, thereby achieving the purpose of convenient storage and transport.

As far as we know, a representative patent for a folding bed with the function of folding in half is shown in Taiwan Model Publication No. M621470 "Foldable Bed Frame Device". The patent includes a first frame unit, a second frame unit and two hinge units. The hinge unit is used for pivoting the first frame unit and the second frame unit, each hinge unit includes a hinge piece, the hinge piece has two spaced apart connecting walls, and a bottom wall connected to one end of the connecting walls, each of the The connecting wall has a first pivot portion pivotally connected to the corresponding first end portion, and a first pivot portion opposite to the corresponding first end portion. The first pivot part is pivotally connected to the second pivot part of the corresponding second end; although the patent has a longitudinal direction in which the second frame unit rotates relative to the first frame unit between an unfolded position and a folded position Folding function; however, this patent does not have the lateral folding function of the side wing support and the side wing bed board, so the bed frame and the bed board cannot have the function of horizontal folding, so that the transverse volume of the bed frame and the bed board cannot be further reduced. , in addition to increasing the storage and handling space, and will increase the cost of freight costs.

In addition, to the best of our knowledge, the US patents for beds with a foldable function are as follows:

1. US2018000254 No. "Folding Bed Frame" is a folding bed frame comprising two symmetrically arranged bed frame units. The two bed frame units are hinged to each other at the joint. The bed frame unit is further provided with a plurality of first support rods hingedly connected with the bed frame unit. The direction in which the plurality of first support rods are folded is perpendicular to the direction in which the bed frame unit is folded.

2. US2020205576 No. "Light bed board and folding bed", which includes a bed frame and a bed board arranged on the bed frame. The bed frame includes a first frame unit and a second frame unit arranged side by side and pivotally connected to each other. The bed board includes a first board unit fixedly arranged on the upper side of the first frame unit and a second board unit fixedly arranged on the upper side of the second bed frame unit. Each of the first panel unit and the second panel unit includes one or more panel elements. Each panel element includes a substrate, a sponge layer and a cover. The base plate is provided on the upper side of the first or second frame unit. The sponge layer is arranged on the upper side of the base material, and the cover layer is arranged on the upper side of the sponge layer.

3. US2021337976 "transportable foldable bed frame", the bed base system includes a base, the base includes a first frame with a bottom and a top, a second frame with a bottom and a top, and the second frame is pivotally connected to the first frame. Connector for the frame. The first frame and the second frame surround the pivot The shafts are selectively pivoted relative to each other such that the first frame and the second frame are selectively pivoted relative to each other between the open, unfolded positions, wherein the top of the first frame and the second frame are substantially coplanar and suitable for In the support mattress and closed folded position, wherein the bottom is folded and the top of the second frame covers the top of the first frame.

4. US2009249545 No. "Portable Folding Bed", a triangular support plate is installed at the junction between the rotating rod of the rotating support rod and the connecting rod to enhance the supporting strength of the rotating support rod, and the fixing plate with the fixed plate plate. A width twice the width of the bed frame is provided in the bed frame engaging unit of the fixed support rod, and a tighter contact unit is provided between the fixed plate and the fixed support rod, so as to obtain a stable engagement of the fixed support rod, and a central support A foldable spring is arranged between the lower cross bar of the rod and the outer frame of the bed frame, so that the folding operation can be conveniently performed in the process of folding the bed.

It can be seen from the above that although the above four US patents have the function of longitudinal folding of the bed frame; however, these US patents do not have the lateral folding function of the side wing support and the side wing bed board, so it is impossible to make the bed frame and the bed board have a horizontal folding function. Because of the folding function, it is impossible to further reduce the lateral volume of the bed frame and the bed board, which not only increases the storage and carrying space, but also increases the cost of freight.

In view of the fact that the above-mentioned conventional technology and the above-mentioned patents are not perfected in the functionality of horizontal folding and have various deficiencies, the creator of this new model has accumulated many years of rich R&D and design experience, actively invested in R&D, and continuously designed it. , Trial production and testing, and finally the research and development results of this new model will be produced.

The main purpose of this new model is to provide a folding bed that can effectively reduce the volume, mainly through the function of vertical and horizontal folding, so that the bed frame assembly and the bed board assembly can be It has both horizontal and vertical folding functions to effectively reduce the volume, and has the characteristics of saving storage space and freight space, facilitating storage and handling and reducing freight costs. The technical means to achieve the above-mentioned main purpose include a bed frame assembly and a bed board assembly. The bed frame assembly includes a main support frame and a plurality of side support members which are sequentially arranged along the longitudinal direction of the bed frame assembly and are respectively located at the sides of the corresponding main support frame. The bed board assembly is disposed on the bed frame assembly and includes a main bed board and a plurality of side wing bed boards which are sequentially arranged along the longitudinal direction of the bed board assembly and are respectively located on the sides of the corresponding main bed board. The side wing supports are respectively extendable and retractable along the lateral direction of the bed frame assembly. The side-wing bed boards can be respectively folded along the lateral direction of the bed board assembly. When the bed board assembly is deployed and used with the bed frame assembly, the side wing supports extend laterally relative to the main support frame to support the bottom of the corresponding side wing bed boards respectively, so as to increase the side wing bed boards to bear the downward pressure towards the bottom of the bed frame assembly.
