Claims (1)

1. A bed frame coupling structure having a double fastening structure for coupling a vertical frame, which is a rectangular member erected vertically at the corner of the bed, and a support frame, which extends horizontally with one end coupled to one side of the vertical frame to form a side portion of the bed, An upper bracket welded to one side of the vertical frame, protruding horizontally from the vertical frame, and having an upper fastening hole formed therein that penetrates vertically; A lower bracket welded to one side of the vertical frame to which the upper bracket is attached, protruding horizontally from the vertical frame, positioned at a certain distance downward from the upper bracket, and having a lower fastening hole formed in the vertical direction; An insert member having a size and shape that is welded to the end portion of the support frame, protrudes horizontally from the support frame, has a through hole formed that penetrates vertically, and can be fitted into the space between the upper bracket and the lower bracket; and It is composed including a fastening part; and When the insert member is inserted into the space between the upper bracket and the lower bracket, the upper fastening hole, the through hole, and the lower fastening hole are arranged in a line along the vertical direction and communicate with each other, and the fastening part is inserted into and fastened to the hole formed by the upper fastening hole, the through hole, and the lower fastening hole, thereby enabling the upper bracket and the lower bracket to be combined with the insert member. The upper bracket and the lower bracket are formed in the shape of a rectangular prism with the same size, so that when the insert member is inserted and combined in the space between the upper bracket and the lower bracket, the upper bracket, the lower bracket, and the insert member come together to form a single rectangular prism, thereby ensuring that the insert member is in close contact with one side of the vertical frame and fixed to the vertical frame so as not to rotate. The above fastening part is a screw with threads formed only on the lower part, and The female screw threads that engage with the screw threads of the above-mentioned fastening part are formed only on the inner circumferential surface of the lower fastening hole of the lower bracket, and the lower end of the screw is coupled to the female screw threads of the lower fastening hole such that the lower end of the screw head contacts the upper surface of the upper bracket, thereby, A bed frame coupling structure having a double fastening structure, characterized by inserting the above screw into the upper bracket, the insertion member, and the lower bracket to temporarily fix the upper bracket and the insertion member to the lower bracket, and then quickly fixing them to the lower fastening hole of the lower bracket by the length of the screw thread.

Description

Joint structure of bed frame with double fastening structure The present invention relates to a joining structure of a bed frame having a double fastening structure, and more specifically, to a structure for joining a vertical frame and a horizontal frame constituting a bed. The frame constituting a conventional bed consists of a vertical frame serving as a column and a support frame forming the side section. The structure is designed so that the connection points between the vertical frame and the support frame are pre-welded and joined using bolts or screws, and the structure allows for transportation, stacking, and installation with all frames connected. However, conventional bed frame structures have the problem that the vertical frame and the support frame are integrally formed by welding or connecting with bolts or screws, which increases costs when stacking large quantities of goods and causes issues with stability. In addition, due to the bulky frame structure, moving and installation take a long time and poses a high risk of safety accidents.

FIG. 2 is an exploded perspective view showing the coupling structure of a bed frame having a double fastening structure according to the present invention. FIG. 3 is a combined perspective view showing the combined structure of a bed frame having a double fastening structure according to the present invention. FIGS. 4 and 5 are schematic exploded perspective drawings showing the coupling structure of a bed frame having a double fastening structure according to one embodiment of the present invention. FIG. 6 is a schematic perspective illustration showing the combined state of a bed frame coupling structure having a double fastening structure according to the present embodiment. FIGS. 7 to 10 are schematic example diagrams showing the usage state of a combined structure of a bed frame having a double fastening structure according to the present embodiment. FIGS. 11 and 12 are schematic diagrams showing other examples of a combined structure of a bed frame having a double fastening structure according to the present embodiment. FIG. 12 is a partially excerpted schematic example showing another example of a combined structure of a bed frame having a double fastening structure according to the present embodiment. Hereinafter, specific embodiments of the present invention will be described in detail with reference to the attached drawings. FIG. 1 is a perspective view showing a bed to which a bed frame coupling structure having a double fastening structure according to the present invention is applied. The joint structure of a bed frame having a double fastening structure according to the present invention can be applied not only to a single-story bed but also to a multi-story bed as shown in FIG. 1. The joint structure of a bed frame having a double fastening structure according to the present invention is a structure for firmly connecting the vertical frame (1) and the support frame (2) of the bed, wherein the vertical frame (1) is a column erected vertically at the four corners of the bed, and the support frame (2) is a member having a square cross-section that extends horizontally to form the left and right sides of the bed, and the left support frame connects two vertical frames (1) located on the left side of the bed, and the right support frame connects two vertical frames (1) located on the right side of the bed. The frame of the bed including the vertical frame (1) and the support frame (2) in this embodiment is made of metal, but is not necessarily limited to metal. FIG. 2 is an exploded perspective view showing the coupling structure of a bed frame having a double fastening structure according to the present invention. The joint structure of a bed frame having a double fastening structure according to the present invention comprises an upper bracket (10), a lower bracket (20), an insert member (30), and a screw (40). The upper bracket (10) and the lower bracket (20) are rectangular members, and one side of the vertical frame (1) is welded to one side of the vertical frame (1), which is a rectangular member. The upper bracket (10) and the lower bracket (20) are welded to the same side of the vertical frame (1) and protrude horizontally in the same direction from the side of the vertical frame (1), and are installed with an upper and lower gap so that the lower surface of the upper bracket (10) and the upper surface of the lower bracket (20) face each other vertically and form parallels. Each of the upper bracket (10) and the lower bracket (20) has a center that is drilled in a straight line from the center of the upper surface to the center of the lower surface, so that an upper fastening hole (11), which is a through hole drilled in a vertical direction, is formed in the upper bracket (10)
