Description

【Technical Field】 【0001】 The present invention relates to the field of beds, and particularly to a bed frame connection structure that is miniaturized, easy to transport, and can be quickly assembled. 【Background Art】 【0002】 Conventional beds such as therapeutic beds and nursing beds in the prior art (for example, Patent Document 1) include a bed body configuration. The bed body configuration includes one bed bottom plate and one bed body frame. The bed bottom plate is connected to the bed body frame via a height adjustment mechanism. Two side rails can be detachably fixed to both sides of the bed body frame. 【0003】 Generally, the bed body frame is welded and integrated, but it was disadvantageous for transportation because of its relatively large volume. Also, the standard of the bed body frame restricted the scope of machine design, so it was disadvantageous for the conversion of other structures. 【0004】 In order to change the structure of the bed, Patent Document 2 discloses a bed in which one main frame is attached to a base frame. Two side frames are coupled to both sides of the main frame, and an elongated area can be expanded toward both sides. The side frame has one frame portion. 【0005】 The joining means described here broadly refers to an assembly structure of a screwing technique combined with a hanging technique. This hanging technique includes one arm portion and one engaging portion. The engaging portion includes one abutting surface portion, two inner opposing surface portions, and one outer opposing surface portion. The two inner opposing surface portions are provided in a curved shape on one side of the abutting surface portion, the outer opposing surface portion is provided in a curved shape on the other side of the abutting surface portion, and together with the inner opposing surface portions, they surround to form one insertion opening. Between the outer opposing surface portion and the frame portion, the arm portion is welded. One opening is formed in the outer opposing surface portion near the arm portion. The opening is located above one insertion hole of the outer opposing surface portion. The screwing technique includes one fastening member having a shaft portion and one nut. 【0006】 When actually attaching it, insert the main frame into the insertion opening of the hook part and bring the contact surface into contact with the upper surface of the main frame. The two inner opposing surfaces face the inner surface of the main frame, and the outer opposing surfaces face the outer surface of the main frame. 【0007】 When actually tightening, the shaft is tilted and inserted into the insertion hole, then inserted into the gap between the two inner opposing surfaces through the two through holes in the main frame. One of the rectangular heads (not shown) of the fastening member is inserted into the insertion hole and through hole, which have substantially the same shape, to prevent the fastening member from rotating relative to the hook. When the nut is tightened onto the shaft, one of the large-diameter parts (not shown) of the fastening member presses against the outer opposing surface, bringing it closer to the main frame. The opening of the arm accommodates a portion of the large-diameter part, preventing it from interfering with the tightening process. 【0008】 As can be seen from the explanation above, the more parts there are, the longer the assembly time. Also, the coupling means for attaching the hook part to the main frame is secured from top to bottom. The screw fastening method used required aligning the insertion hole with the through hole in order to screw the nut onto the shaft, so this assembly work required experienced workers. 【0009】 Therefore, there was a need for technology that could improve upon the shortcomings of conventional technologies.

As shown in FIG. 1, the connecting member 10 of the bed frame connecting structure according to the first embodiment of the present invention has a long plate 11. The long plate 11 has two long sides (not numbered), and four coupling holes 13 are formed on one long side, and the other long side is connected to a single short plate 12. Two of the coupling holes 13 are provided near one corner of the long plate 11, and the remaining two coupling holes 13 are provided near the other corner of the long plate 11. 【0024】 The short plate 12 is bent at approximately 90 degrees relative to the long plate 11. This forms the connecting member 10 into a mechanical structure similar to an angle steel. Two projections 14 are formed on the front surface (not indicated by a reference numeral) of the short plate 12. The projections 14 are located close to the long side of the short plate 12 and away from the long plate 11. Two recesses 17 are recessed on one of the back surfaces (not indicated by a reference numeral) of the short plate 12 (see Figure 2). By aligning the recesses 17 with the projections 14, the structural strength of the short plate 12 can be increased. A connecting hole 15 is formed in the short plate 12, penetrating from the projections 14 to the recesses 17 in the thickness direction. 【0025】 The connecting member 10 has three ribs 16 and three notches 18. The three ribs 16 are provided as protrusions at the corners where the long plate 11 and the short plate 12 are connected substantially perpendicularly. The three notches 18 (see Figure 2) are recessed in the ridge structure (not indicated by a reference numeral) formed by the connection of the long plate 11 and the short plate 12. By aligning the notches 18 with the ribs 16, the structural strength of the connecting member 10 can be increased. 【0026】 Refer to Figure 3. As shown in Figure 3, the correspondence between the two long rods 21 of the four connecting members 10 of the bed frame connecting structure according to the first embodiment of the present invention and their attachment to one base 27 is shown. 【0027】 The base 27 of the bed frame connecting structure according to the first embodiment of the present invention has one frame 28. One leg 29 is attached to each of the four corners of the frame 28. The length of each leg 29 is equal. Since the four legs 29 can each support the frame 28 and maintain a constant height from a plane (e.g., the floor), the base 27 belongs to the category of a fixed base. 【0028】 The two opposing sides of the two elongated rods 21 are considered to be the inner sides 22. In the first embodiment, four rivets 19 are inserted through corresponding connecting holes 13 (see Figure 1 or Figure 2) to securely fix the elongated plate 11 to the inner sides 22 of the elongated rods 21. In other embodiments, the elongated plate 11 may not have connecting holes and may be securely fixed to the inner sides 22 of the elongated rods 21 by welding, which is also within the scope of the present invention. 【0029】 The four fixing seats 24 are welded to the inside 22 of the long rod 21. Two of the four fixing seats 24 are located near both ends of the long rod 21, and the remaining two fixing seats 24 are located between the two connecting members 10. Each fixing seat 24 has one screw hole 25. 【0030】 Refer to Figure 4. As shown in Figure 4, four short rods 23 are joined to two long rods 21 to jointly assemble a bed frame 20 that is roughly rectangular in shape. The short rods 23 are connected by being stretched across two opposing fixing seats 24. Two fastening members 26 are inserted through both ends of the short rods 23 and connected to screw holes 25 (see Figure 3). The screw holes 25 have female threads, as the name suggests. The fastening members 26 in the first embodiment are screws, bolts, or screw rods having male threads. 【0031】 When the other fastening members 26 are inserted through the connection holes 15 (see Figure 3) and screwed into the frame 28, the short plate 12 and the base 27 are joined together. 【0032】 To elaborate on the effects, the connecting member 10 can connect the bed frame 20 to the upper surface of the base 27. Because the length of the short rod 23 is greater than the width of the frame 28, the area of ​​the bed frame 20 in the first embodiment is larger than the area of ​​the bed frame integrated by welding in Patent Document 1 (Chinese Utility Model Publication No. 213489949). In the first embodiment, after removing the fastening member 26 and disassembling the bed frame 20 into the long rod 21 and short rod 23, it not only takes up less space but can also be stored in a smaller packaging container. Furthermore, because the transport space is small, the transport efficiency can be increased, and after being transported to the destination, it can be quickly assembled on site. 【0033】 In the first embodiment, the fastening member 26 is joined from top to bottom, which assists in attaching the connecting member 10 to the upper surface of the frame 28. Therefore, compared to the conventional method described in Patent Document 2 (Patent Application Publication No. 2024-82059), which involves attaching the connecting member 10 to the main frame from top to bottom using a hook and tightening it from the outside to the inside, the assembly time is shorter. 【0034】 Refer to Figures 4 and 6. As shown in Figures 4 and 6, one headboard 41 is attached to one end of the bed frame 20. One footboard 42 is attached to the other end of the bed frame 20. Two side panels 43 are attached to both sides of the bed frame 20, respectively. On the top surface of the bed frame 20, one back panel frame 44, one intermediate panel frame 45, one thigh panel frame 46, and one lower thigh panel frame 47 are arranged. The intermediate panel frame 45 is fixed to the bed frame 20 and does not move, and attaches one intermediate panel (not shown). The back panel frame 44 is pivotably connected between the headboard 41 and the intermediate panel frame 45 and attaches one back panel (not shown). The thigh panel frame 46 is pivotably connected to the intermediate panel frame 45, is not located at the same end as the back panel frame 44, and attaches one thigh panel (not shown). The thigh plate frame 47 is pivotably connected between the footboard 42 and the thigh plate frame 46, and a single thigh plate (not shown) is attached. Therefore, the base 27 is attached below the bed plate frame 20, and together they form a single bed frame 40 of the same height. 【0035】 (Second example) Refer to Figure 5. The bed frame connecting structure according to the second embodiment of the present invention is substantially the same as that of the first embodiment, except that there is no base. The two lifting seats 30 replace the base and are provided on both sides below the bed board frame 20. 【0036】 The lifting seat 30 according to the first embodiment has one base frame 31. The base frame 31 similarly has four legs 33. These legs 33 are connected to the four corners of the base frame 31 and contact one plane (e.g., the floor) to support the weight of the lifting seat 30, the bed board frame 20 and the entire bed frame 40 (see Figure 6). A lifting mechanism 34 is mounted on the base frame 31. A top frame 32 is connected to the lifting mechanism 34. The height from the top frame 32 to the base frame 31 is adjustable. The method for adjusting the height of the lifting mechanism 34 is not the technical core of the present invention and will not be described in detail here, but this technology is disclosed in Taiwan Utility Model Registration No. M660083. 【0037】 The fastening member 26 is inserted through the connecting hole 15 from top to bottom, and the connecting member 10 is attached to the upper surface of the top frame 32. The two lifting seats 30 are attached to both sides below the bed board frame 20, and the bed frame 40 can be combined together (see Figure 6) to adjust the height. 【0038】 Refer to Figure 6. As shown in Figure 6, the bed frame 20 has a headboard 41 attached to one end and a footboard 42 attached to the other end. Two side panels 43 are attached to both sides of the bed frame 20. An intermediate panel (not shown) is attached to the bed frame 20 via an intermediate panel frame 45. A back panel (not shown) is attached to the bed frame 20 via a back panel frame 44. A thigh panel (not shown) is attached to the bed frame 20 via a thigh panel frame 46. A lower thigh panel (not shown) is attached to the bed frame 20 via a lower thigh panel frame 47. 【0039】 Preferred embodiments of the present invention have been disclosed above so that they can be understood by those familiar with the technology in this field, but these do not limit the invention. Various changes and modifications can be made without departing from the spirit and scope of the invention. Accordingly, the claims of the present invention should be interpreted broadly to include such changes and modifications.
