Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a disassembled and assembled bed frame, and more specifically, to front and rear head frames and end frames of the bed frame,
The present invention relates to the improvement of the connection structure between the left and right side rods provided between these two frames.

[Conventional technology]

Generally, the bed frame is made of wood or metal, and in order to make the metal one lightweight, pipe materials are mostly used. However, the prefabricated bed frame made of metal pipe is
Usually, a head frame having various decorations, an end frame facing the frame, and left and right side rods connecting the head frame and the end frame (and left and right side rods connected at an intermediate portion) (Including the intermediate frame), and these components mainly have a head frame and an end frame, which are opposed to each other in the front-rear direction, between both sides. The left and right side rods are connected so that they can be assembled. However, as the connecting structure, in addition to the type in which a nut is screwed and connected to the threaded portion of the stud planted in a part, as the fitting type, as shown in FIG. 4 (hereinafter, a part thereof will be shown) When welding the female tool b forming a right-angled triangle in a side view to one side surface of the frame a, when welding one side b ₁ sandwiching the right angle of the female tool,
The other side b ₂ having a rectangular cross section and a concave portion b'having a narrower pyramidal shape at the lower side is fixed so that the upper plane is formed, and the concave portion b'is provided at one end of the side rod c. Weld a wedge-shaped male tool d that can be fitted from above into the female tool b,
The male tool d is inserted from the lower tip into the recess b'of the female tool b to connect the frame a and the side rod c. In addition, it is also known that the female tool is a round (square) pipe and the male tool is a circular (square) rod-shaped member.

[Problems to be solved by the invention]

By the way, the connection type using the above-mentioned bolt and nut has the drawback that not only is disassembling and assembling troublesome, but also parts are easily lost. Further, a wedge-shaped male tool d is provided in the female tool b.
In order to prevent the side rod c from rattling with respect to the frame a at the time of fitting, the female tool b and the male tool d must have the same angle so that all pairs are fitted. The contact surfaces must be formed so as to be in intimate contact with each other, and precision is required for processing and mounting. Further, if the female tool is a round (square) pipe and the male tool is a circular (square) rod-shaped member, it becomes difficult to perform the alignment at the time of fitting, which is troublesome.

It is an object of the present invention to eliminate the above-mentioned adverse effects and enable quick and simple disassembly and assembly, and to easily adjust the parallelism of the front and rear frame bodies and the left and right side rods in the bed frame.

[Means for solving problems]

A bed frame according to the present invention comprises a head frame, an end frame opposite to the rear part of the frame, and an upper head frame and left and right side rods interposed between the frames. In the above, a pipe material having square holes each having a square cross section formed in the vertical direction is fixed to the inner surface of each vertical member facing the front and rear parallels of the head frame and the end frame, and the left and right side rods A circular rod-shaped member, which is perpendicular to the side rod and has an outer diameter slightly smaller than the dimension between the facing surfaces of the square holes, is fixed to each end.

[Action]

The bed frame of the present invention has a square hole made of pipe material fixed to the inner surface of each vertical member in the head frame and the end frame,
When the rod-shaped members at the ends of the side rods are inserted from the upper side in the vertical direction, the front and rear frames and the left and right rods on the left and right sides are integrally assembled to be used as a bed. However, as long as the former pipe material is fixed vertically to each vertical member of the head frame and the end frame, and the latter rod-shaped material is fixed at a right angle to the side rod, keep the side rod horizontal. In addition, since the rod-shaped member can freely rotate within the pipe member about the axis of the pipe, the parallelism between the head frame and the end frame can be freely adjusted. Further, the disassembly of the bed frame can be achieved by pulling the rod-shaped bar-shaped member upward from each pipe member.

〔Example〕

An embodiment of the present invention will be described below with reference to FIGS. 1 to 3. Reference numeral 1 denotes a head frame 2 and an end frame 3 which are arranged in parallel in the front-rear direction and between both sides of the head frame and the end frame. A bed frame composed of left and right side rods 4 interposed between the head frame 2 and the end frame 3 so that the head frame 2 and the end frame 3 can be vertically balanced by the left and right legs 2'and 3 ', respectively. The frame 2 is provided with a decorative frame 2 ″. The head frame 2 and the end frame 3 are made of metal round pipes respectively, and the side rods 4 are made of the same angle pipe, so that the whole is lightweight. Reference numeral 5 indicates a vertical member (each leg is shown in the figure) of the head frame and the end frame facing each other in the front-rear direction. It is a fixed pipe material, and a square hole 5'having a square cross section is provided in the inside in the vertical direction.
Is a circular rod-shaped member that is fixed to the outer end portion of the rectangular hole 5 ′ so as to project downward in the direction perpendicular to the outer end of the rectangular hole 5 ′ so that the rod-shaped member can be inserted into the square hole 5 ′ in an inscribed state. It is slightly smaller than the dimension of the face-to-face contact in '.

Each of the left and right side rods 4 may be formed of a long single body, but when the strength is insufficient, the side rods are divided into two parts, the front and rear parts, and the inner ends of the opposing rods are fitted to the outer periphery. It is preferable that the connecting pipes 7 are connected and the left and right relay pipes 7 are supported by both leg portions 8'of the reinforcing rod 8 whose lower portions are in contact with the floor surface.

In the case of the above configuration, the head frame 2 and the end frame 3 are leaned by the leg portions 2'and 3'and fixed to the opposing inner side surfaces of the frames, respectively. The required bed frame can be assembled by sequentially inserting the rod-shaped members 6 provided at the ends of the side rods 4 into the ′ direction substantially vertically.

By the way, the pipe member 5 has a square hole 5'having a square cross section, and a rod-shaped member 6 fitted in the square hole in an inscribed state is circular so that its outer diameter is the same as that of the square hole 5 '. Since it is set to be slightly smaller than the face-to-face dimension, unlike the case where both the hole and the rod-shaped member of this pipe material are square or circular, it is easy to insert and fit, and at the time of the above-mentioned assembly Since the other end of the rod 4 can be pivotally moved to the left and right around the axis of the square hole 5'in the pipe material 5, the fitting work can be facilitated and
The parallelism between the head frame 2 and the end frame 3 can be freely adjusted.

[Effect of device]

As described above, according to the present invention, since the circular rod-shaped member of the side rod is inserted into the square holes provided in the head frame and the end frame to assemble the bed frame, it is easy to assemble and disassemble the bed frame. , Not only swiftly, but even if the outer peripheral surface of one circular rod-shaped material that is exposed to the outside in a disassembled state has some irregularities on the outer peripheral surface, the rod-shaped material is appropriately rotated. With this, it is possible to insert it smoothly into the square hole, and by this rotation, the flaw can be healed naturally. When one side of the bed frame is to be assembled along the wall surface in the room, the side rods may be placed outside the wall at right angles to the head frame and the end frame at a wide position away from the wall. After assembling at an angle, it is possible to take an installation means such as moving the whole body near the wall surface and correcting and arranging it in parallel.In addition, according to the present invention, the processing accuracy in each part and the fitting part is considerably loose. Therefore, it can be processed easily and can be provided at low cost.
