Definitions

  • the present invention relates to the technical field of furniture materials and furniture manufacture, and is specifically an artificial wood board having a sequential artificial arrangement applicable to furniture and beddings.
  • artificial laminated boards and plywood are generally used in the market to replace original natural monolithic wood boards.
  • the artificial laminated boards and plywoods generally have the following problems:
  • Insufficient strength Most laminated boards or plywoods are made by pressing wood chips and glue under a high pressure and a high temperature. However, a pulling force between the internal wood chips is insufficient. In order to achieve a design strength, a thickness of the laminated board or the plywood needs to be increased.
  • the present invention aims to provide an artificial wood board and a bed frame using the wood board.
  • the artificial wood board has the same thickness but higher strength, hardly uses glue, and is less prone to dampness and peeling-off of edges.
  • An artificial wood board applicable to furniture includes at least an upper layer of wood shavings, an intermediate layer of wood shavings, and a lower layer of wood shavings that are directionally laid.
  • the upper layer of wood shavings and the lower layer of wood shavings are arranged in a designated direction along a length or a width of the board.
  • the artificial wood board provided in the present invention uses large wood particles and large wood pieces during fabrication.
  • the traditional plywoods and laminated boards use fine wood chips.
  • the artificial wood board provided in the present invention has a three-layer structure. Wood materials are laid in a different direction in each layer. Therefore, the artificial wood board provided in the present invention can be thinner with the same strength. In this way, the artificial wood board provided in the present invention is applicable to indoor furniture.
  • a method for fabricating the artificial wood board applicable to furniture includes:
  • step 1 fabricating a mold according to the length, the width, and a thickness of the wood board;
  • step 2 preparing shavings and adding auxiliary glue to the shavings
  • step 3 laying the lower layer of shavings in the mold along the length or the width of the wood board;
  • step 4 laying the intermediate layer of shavings on the lower layer of shavings
  • step 5 laying the upper layer of shavings on the intermediate layer of shavings along the length or the width of the wood board;
  • step 6 placing the mold into a pressure device for heating and pressing, so that the shavings finally form a wood board having a multi-layer structure.
  • the artificial wood board obtained by using the fabricating method has the following mechanical properties:
  • the artificial wood board provided in the present invention has a more desirable dampness resistance property. Therefore, compared with traditional plywoods and laminated boards, the artificial wood board provided in the present invention can be used as a bed board.
  • the present invention provides a bed frame using the foregoing artificial wood board.
  • the bed frame includes a metal frame and the artificial wood board.
  • the artificial wood board is laid on the metal frame and connected to the metal frame by using bolts.
  • the metal frame includes a front frame and a rear frame that are rotatably connected to each other and a front push rod assembly and a rear push rod assembly respectively disposed on the front frame and the rear frame
  • the artificial wood board includes a front bed board assembly and a rear bed board assembly respectively laid on the front push rod assembly and the rear push rod assembly.
  • the bed frame further includes a driving motor.
  • the front push rod assembly and the rear push rod assembly are connected to the driving motor and configured to drive the bed board assemblies to be folded upward under driving of the driving motor.
  • the driving motor When the driving motor is at an initial position, the front frame, the rear frame, the push rod assemblies, and the driving motor all fall within a range of thicknesses of the front frame and the rear frame.
  • the bed frame provided in the present invention is specifically a foldable bed frame. Since the bed frame uses an ultra-thin metal frame structure and the artificial wood board is designed to be thin, the bed frame is much thinner than a traditional foldable bed frame, facilitating assembly, packaging, transportation, and usage in a small space.
  • the bed frame further includes two intermediate links.
  • the two intermediate links rotatably connect the front frame to the rear frame on two sides, so that the front frame and the rear frame are foldable inward by using the intermediate links.
  • the front push rod assembly includes a pair of slidable rods and a pair of guide rods respectively disposed on two sides of the front frame, the slidable rods are rotatably connected to the guide rods, and the guide rods are slidably connected to the front frame driving motor, so that the slidable rods are driven by the front frame driving motor to move under guidance of the guide rods.
  • a roller is disposed on each of the slidable rods of the front push rod assembly, and the slidable rods are configured for rolling contact with bed boards by using the rollers.
  • the rear push rod assembly includes a pair of leg slidable rods and a pair of leg guide rods respectively disposed on two sides of the rear frame, the leg slidable rods are rotatably connected to the leg guide rods, the leg guide rods are slidably connected to the rear frame driving motor, so that the leg slidable rods are driven by the rear frame driving motor to move under guidance of the guide rods, and the rear push rod assembly further includes a foot support rod rotatably connected to the rear.
  • a roller is disposed on each of the leg slidable rods of the rear push rod assembly, and the leg slidable rods are configured for rolling contact with the rollers by using the rollers.
  • the rear bed board assembly includes a leg bed board and a foot bed board, the leg bed board is disposed above the leg slidable rods, and the foot bed board is disposed above the foot support rod.
  • the bed frame provided in the present invention further has the following beneficial effects:
  • the arrangement of the dual motors simplifies overall complexity of the push rod assemblies of the front frame and the rear frame, facilitating reliability of the foldable bed frame.
  • the intermediate links rotatably connect the front frame to the rear frame on two sides, so that the front frame and the rear frame are foldable inward by using the intermediate links. In this way, the front frame and the rear frame are prevented from colliding or interfering with each other during folding and storage, facilitating operations for a user.
  • the front bed board assembly and the rear bed board assembly are rotatably connected to each other by using hinges. Holes are provided on the artificial wood board and rivets are disposed, a threaded hole is provided in the middle of each of the rivets, and the artificial wood board is connected to the metal frame by means of connection between the threaded holes and the bolts.

Abstract

Un panneau de bois artificiel présente un agencement artificiel séquentiel applicable à des meubles et un cadre de lit le mettant en œuvre. Le panneau de bois artificiel comprend au moins une couche supérieure de copeaux de bois, une couche intermédiaire de copeaux de bois et une couche inférieure de copeaux de bois qui sont disposées de manière orientée. La couche supérieure de copeaux de bois et la couche inférieure de copeaux de bois sont agencées de manière orientée sur une longueur ou une largeur du panneau. Le cadre de lit comprend un cadre métallique et le panneau de bois artificiel. Le panneau de bois artificiel est posé sur le cadre métallique et relié au cadre métallique par des boulons. Comme le cadre de lit met en œuvre une structure de cadre métallique ultra-mince et comme le panneau de bois artificiel est conçu pour être mince, le cadre de lit est bien plus fin qu'un cadre de lit pliant traditionnel, facilitant l'assemblage, le conditionnement, le transport et l'utilisation dans un espace réduit.
