Description

Technical Field

[0001] This invention relates to the field of bedding, and more specifically to a bed frame fixing structure. Background Technology

[0002] A bed is an essential part of people's lives. A bed generally consists of a bed frame and a mattress. The bed frame includes two headboards, two side beams connecting the two headboards, and bed slats connecting the two side beams.

[0003] For ease of transport, the headboard, side beams, and slats of the bed frame are separate and assembled upon arrival at the destination. For metal bed frames, the slats are typically attached to the side beams with screws or bolts. During assembly, each slat must be screwed to both ends of the two side beams, and since bed frames usually have several slats, this requires multiple screwing operations during assembly, making installation very inconvenient. Summary of the Invention

[0004] In view of the problems existing in the prior art, the purpose of this invention is to provide a bed frame fixing structure that is easy to install.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0006] A bed frame fixing structure includes two headboards, two side beams, and several bed slats. The side beams are connected between the two headboards and are parallel to each other. The bed slats are connected between the two side beams and are connected to the side beams via connectors. The side beams are provided with fixing grooves that mate with the connectors. The two ends of the bed slats are provided with plug-in portions that mate with the connectors, and the plug-in portions are provided with fixing holes.

[0007] The connector includes a connector body, a connector hole, a locking block, and a hook. The connector portion of the bed slat is used to insert into the connector hole from the front. The locking block connects to the connector body and extends into the connector hole.

[0009] The insert portion of the bed slat includes a left section, a right section, and a middle section. The middle section is flat, while the left and right sections are tubular. Correspondingly, the insert hole includes two tubular sections and a flat section. When the insert portion is inserted into the insert hole, the left and right sections are located in the two tubular sections, while the middle section is located in the flat section.

[0010] The fixing hole is located in the middle section of the insertion part, and the snap-fit ​​block is located in the flat part of the insertion hole.

[0011] The snap-fit ​​block is provided with an unlocking hole, which allows an unlocking tool to be inserted from the front of the connector.

[0016] When the first connecting piece and the second connecting piece are at the maximum insertable angle, there is a gap d between the two first locking parts located on the same side of the first riveting part; wherein, the maximum insertable angle refers to the maximum angle between the first connecting piece and the second connecting piece when the first connecting assembly is in the state of being insertable into the inner cavity of the side beam unit; when the angle between the first connecting piece and the second connecting piece is greater than the maximum insertable angle, the first hinge part cannot be inserted into the side beam unit; the size of the through hole is greater than the size of the screw hole.

[0017] The connecting piece is also provided with a first bending portion, one end of which is connected to the first riveting portion and the other end is connected to the first locking portion. The first bending portion bends toward the second side of the first riveting portion, and the second side is opposite to the first side.

[0018] The first bending portion includes a first bending segment and a second bending segment. The first bending segment is bent relative to the first riveting portion, and the second bending segment is bent relative to the first bending portion.

[0019] The connecting piece is a one-piece molded structure.

[0020] The bed side beam and the headboard are connected by a second connecting assembly, which includes two connecting blocks, namely a first connecting block and a second connecting block. Each connecting block includes a second riveting part and a second locking part. The second locking part is connected to one end of the second riveting part and is located on the first side of the second riveting part. The first connecting block and the second connecting block are riveted at the second riveting part, and the first sides of the two second riveting parts are in contact.

[0021] The second locking part of the first connecting block and the second connecting block is inserted into the bed side beam. The second locking part is provided with a screw hole, and the bed side beam is provided with a second through hole that mates with the screw hole.

[0023] The second locking part of the first connecting block is located above the second locking part of the second connecting block, and the locking block is disposed on the second riveting part of the first connecting block.

[0024] The second locking part of the first connecting block is provided with a limiting block at one end near the headboard, and correspondingly, the headboard is also provided with a limiting hole that cooperates with the limiting block.

[0025] The limiting hole and the card hole are connected.

[0026] The connecting block is also provided with a second bending portion, one end of which is connected to the second riveting portion and the other end is connected to the second locking portion.

[0030] The bed frame fixing structure also includes a ladder, which is connected to the headboard or side beam.

[0031] By adopting the above solution, the present invention has the following beneficial effects:

[0032] I. This invention uses a plug-in connector to connect the bed slats and side beams, allowing the bed slats to be connected to the side beams via a plug-in method, making installation more convenient. Simultaneously, the plug-in connector is stably connected to the side beams via hooks, and the bed slats are not simply plugged into the connectors, but rather, based on the plug-in connection, a stable connection between the bed slats and the connectors is achieved through the cooperation of a snap-fit ​​block and a fixing hole, thereby achieving a stable connection between the bed slats and the side beams. Therefore, this invention achieves a simple, quick, and stable connection between the bed slats and side beams by using a plug-in connector, making bed frame installation much more convenient.

[0033] Second, regarding the broken bed side beams, this invention utilizes a first connecting assembly to connect the two side beam units. This first connecting assembly consists of two cross-riveted first connecting pieces and a second connecting piece. When the first connecting assembly is inserted into the side beam unit, it still has a certain amount of deformation space. Therefore, when bolts are used for locking, the first hinge part of the first connecting assembly will move towards the inner wall of the side beam unit and fit tightly against it, thereby improving the connection strength between the side beam units.

[0034] Third, this invention utilizes a second connecting assembly to connect the bed side beams and the headboard. This second connecting assembly consists of two riveted first connecting blocks and a second connecting block. When the second connecting assembly is inserted into the bed side beam, it still has a certain amount of deformation space. Therefore, when bolts are used for locking, the second hinge part of the second connecting assembly will move towards the inner wall of the bed side beam and fit tightly against it, thereby improving the connection strength between the side beam units.

Implementation

[0058] like Figure 1 As shown, the present invention discloses a bed frame fixing structure, which includes two headboards 30, two side beams 20, and several bed slats 10. The side beams 20 are connected between the two headboards 30 and are parallel to each other. The bed slats 10 are connected between the two side beams 20.

[0059] For ease of installation, the bed slats 10 and the bed side beams 20 are connected by a snap-fit ​​mechanism. Specifically, as shown... Figure 2-8 As shown, the bed slats 10 are connected to the bed side beams 20 via connectors 50. The bed side beams 20 are provided with fixing grooves 22 that mate with the connectors 50. Both ends of the bed slats 10 are provided with plug-in portions 11 that mate with the connectors 50, and each plug-in portion 11 is provided with fixing holes 12.

[0060] The connector 50 includes a connector body 51, and a connector hole 52, a locking block 53, and a hook 54 disposed on the connector body 51. The connector portion 11 of the bed slat 10 is used to insert into the connector hole 52 from the front of the connector 50. The locking block 53 connects to the connector body 51 and extends into the connector hole 52. When the connector portion 11 of the bed slat 10 is inserted into the connector hole 52, the locking block 53 engages with the fixing hole 12 of the connector portion 11. The hook 54 is disposed on the back of the connector 50. When the connector 50 is installed in the fixing groove 22, the hook 54 engages with the inner wall of the fixing groove 22.

[0061] In use, the connector 50 can be pre-installed in the fixing groove 22 of the bed side beam 20 and fixed to the bed side beam 20 by a snap fastener. When connecting the bed slat 10 to the bed side beam 20, simply insert the plug part 11 of the bed slat 10 into the plug hole 52 from the front of the connector 50. At this time, the snap-fit ​​block 53 of the connector 50 will snap into the plug hole 52, thus fixing the bed slat 10 to the connector 50 and completing the connection between the bed slat 10 and the bed side beam 20.

[0062] Because the insertion part 11 of the bed slat 10 needs to be inserted into the connector 50, if the insertion part 11 of the bed slat 10 is too large, the volume of the connector 50 and the bed side beam 20 will also increase, which will undoubtedly increase the cost of the entire bed frame. Therefore, the insertion part 11 of the bed slat 10 can be set as a flat structure, and correspondingly, the insertion hole 52 is set as a flat hole.

[0063] To reduce the cost of the bed frame while ensuring the stability of the connection between the bed slats 10 and the connector 50, in this embodiment, the connector portion 11 of the bed slats 10 is divided into a left side section 111, a middle section 112, and a right side section 113 from left to right. The middle section 112 is flat, while the left side section 111 and the right side section 113 are tubular. Correspondingly, the connector hole 52 includes two tubular portions 521 and a flat portion 522. When the connector portion 11 is inserted into the connector hole 52, the left side section 111 and the right side section 113 are located in the two tubular portions 521 of the connector hole 52, while the middle section 112 is located in the flat portion 522 of the connector hole 52. Based on the above, the fixing hole 12 is located in the middle section 112 of the connector portion 11, and the snap-fit ​​block 53 is located in the flat portion 522 of the connector hole 52.

[0064] To facilitate the disassembly of the bed slats 10 and the side beams 20, the locking block 53 is provided with an unlocking hole 531, which allows an unlocking tool to be inserted from the front of the connector 50. During disassembly, the unlocking tool is inserted into the unlocking hole 531, and then pressure is applied to disengage the locking block 53 from the hole. The unlocking tool can be a screwdriver or other tool that can be inserted into the unlocking hole 531 and allows for easy application of force.

[0065] In this embodiment, the snap-fit ​​block 53 includes a connecting portion 532 and a snap-fit ​​portion 533. The snap-fit ​​portion 533 is used to snap into the fixing hole 12 of the insertion portion 11, and the connecting portion 532 is provided with the unlocking hole 531. The connecting portion 532 is provided with a first side 5321, a second side 5322, a third side, and a fourth side 5323. The first side 5321 and the third side are arranged opposite to each other, as are the second side 5322 and the fourth side 5323. The first side 5321 is connected to the snap-fit ​​portion 533, and the third side is connected to the insertion body 51. A gap 534 is formed between the second side 5322 and the fourth side 5323 and the insertion body 51. The gap 534 allows the snap-fit ​​block 53 to have a certain deformation capability, which makes it easier to assemble and disassemble the bed slats 10.

[0066] Currently, for ease of packaging and transportation, the bed side beam 20 is generally divided into multiple segments, meaning the bed side beam 20 comprises two or more bed side beam 20 units. In this case, to facilitate the installation between the bed side beam 20 units and ensure the stability of the connection structure, the present invention employs a first connecting component 60 to lock two adjacent side beam units 21 together.

[0067] Specifically, such as Figure 9-12As shown, the first connecting assembly 60 includes two connecting pieces, namely a first connecting piece 61 and a second connecting piece. Each connecting piece includes a first riveting portion 601 and two first locking portions 602. The two first locking portions 602 are respectively connected to both ends of the first riveting portion 601, and both first locking portions 602 are located on the first side of the first riveting portion 601. The first connecting piece 61 and the second connecting piece 62 are arranged crosswise, and the first connecting piece 61 and the second connecting piece 62 are riveted together at the riveting portion, with the first sides of the two first riveting portions 601 abutting against each other. The first locking portion 602 is inserted into the side beam unit 21, and the first locking portion 602 has a screw hole. The side beam unit 21 has a first through hole 211 that mates with the screw hole. The side beam unit 21 and the first connecting assembly 60 are fixed together by bolts, which are locked through the first through hole 211 and locked with the screw hole of the first locking portion 602.

[0068] When using the first connecting assembly 60 to connect two adjacent side beam units 21, adjust the distance between the first connecting piece 61 and the second connecting piece 62 so that the vertical height of the first connecting assembly 60 is less than the inner cavity height of the side beam unit 21. This makes inserting the first connecting assembly into the side beam unit 21 easier and simpler. Then, insert both ends of the connecting assembly into the two side beam units 21 respectively, aligning the screw hole of the first locking part 602 with the first through hole 211 of the side beam unit 21. Next, pass a bolt through the first through hole 211 and lock it into the screw hole of the first locking part 602. Because the first connecting piece 61 and the second connecting piece 62 are riveted, during the process of locking the bolt into the screw hole of the first locking part 602, the first riveting part 601 will move towards the inner wall of the side beam unit 21, making the first riveting part 601 tightly adhere to the inner wall of the side beam unit 21, thereby improving the connection strength between the connecting assembly and the side beam unit 21.

[0069] In this embodiment, the size of the through hole is larger than the size of the screw hole. For example, the through hole is set as an elongated hole, while the screw hole is a round hole. When the first connecting piece 61 and the second connecting piece 62 are at the maximum insertable angle α, there is a gap d between the two first locking parts 602 located on the same side of the first riveting part 601. The maximum insertable angle α refers to the maximum angle between the first connecting piece 61 and the second connecting piece 62 when the first connecting assembly 60 can be inserted into the cavity of the side beam unit 21. When the angle between the first connecting piece 61 and the second connecting piece 62 is greater than the maximum insertable angle α, the first hinge part cannot be inserted into the side beam unit 21. Therefore, in this case, when connecting the two side beam units 21 using the connecting assembly, the angle between the first connecting piece 61 and the second connecting piece 62 is adjusted to the maximum insertable angle, and then the first hinge part is inserted into the cavity of the side beam unit 21, and the first through hole 211 is aligned with the screw hole; then, a bolt is passed through the through hole and locked in the screw hole. During the rotation of the bolt, the first locking part 602 moves toward the first riveting part 601 toward the inner wall of the side beam unit 21, and the gap d gradually decreases. When the first riveting part 601 is in close contact with the inner wall of the side beam unit 21, the gap d becomes 0, so that the two first riveting parts 601 located on the same side abut together, which further improves the connection strength between the connecting assembly and the side beam unit 21.

[0070] In this invention, the connecting piece further includes a first bending portion 603. One end of the first bending portion 603 is connected to the first riveting portion 601, and the other end is connected to the first locking portion 602. The first bending portion 603 bends towards a second side of the first riveting portion 601, with the second side and the first side having opposite directions. Specifically, the first bending portion 603 includes a first bending segment 6031 and a second bending segment 6032. The first bending segment 6031 bends relative to the first riveting portion 601, and the second bending segment 6032 bends relative to the first bending portion 603. The first bending portion allows the riveting portions of the first connecting piece 61 and the second connecting piece 62 to fit better, ensuring connection stability and improving the strength of the connecting piece. Furthermore, the first bending portion 603 allows the edges of the first and second sides of the two first locking portions 602 of the same connecting piece to be aligned, thus balancing the load-bearing capacity of the connecting piece.

[0071] Similarly, in order to make the assembly between the bed side beam 20 and the headboard 30 more convenient and the connection structure more stable, the present invention uses a second connecting component 70 to connect the bed side beam 20 and the headboard 30.

[0072] Specifically, such as Figure 13-15As shown, the second connecting assembly 70 includes two connecting blocks, namely a first connecting block 71 and a second connecting block 72; each connecting block includes a second riveting portion 701 and a second locking portion 702, the second locking portion 702 being connected to one end of the second riveting portion 701 and located on the first side of the second riveting portion 701; the first connecting block 71 and the second connecting block 72 are riveted at the second riveting portion 701, and the first sides of the two second riveting portions 701 are in contact.

[0073] When the second connecting assembly 70 is locked to the bed side beam 20, the second locking part 702 of the first connecting block 71 and the second connecting block 72 is inserted into the bed side beam 20. The second locking part 702 and the bed side beam 20 are provided with matching screw holes. The bolts are used to lock the bed side beam 20 and the second locking part 702 into the screw holes, thus realizing the connection between the bed side beam 20 and the second locking part 702.

[0074] The second riveting portion 701 of the first connecting block 71 or the second connecting block 72 is provided with a locking block 704, which forms a groove 7041 with the second riveting portion 701, and the groove 7041 faces downward; the headboard 30 is provided with a locking hole 321. When the locking block 704 is inserted into the locking hole 321, the side wall of the locking hole 321 is inserted into the groove 7041, thereby realizing the connection between the second connecting assembly 70 and the headboard 30.

[0075] The headboard frame 30 includes a horizontal support assembly 31 and two vertical support rods 32. The horizontal support assembly 31 is connected between the two vertical support rods 32, and the vertical support rods 32 are provided with the aforementioned locking holes 321. That is, the bed side beam 20 is connected to the vertical support rods 32 of the headboard frame 30 through the second connecting assembly 70.

[0076] In this embodiment, the second locking part 702 of the first connecting block 71 is located above the second locking part 702 of the second connecting block 72, and the locking block 704 is disposed on the second riveting part 701 of the first connecting block 71. To enhance the connection stability between the bed side beam 20 and the vertical support rod 32 and prevent them from easily separating, this embodiment provides a limiting block 705 at one end of the second locking part 702 of the first connecting block 71 near the headboard 30. Correspondingly, the headboard 30 is also provided with a limiting hole that cooperates with the limiting block 705. In this embodiment, the limiting hole and the locking hole 321 are connected, forming an elongated hole.

[0077] To increase the connection strength of the second connecting assembly 70, the connecting block is further provided with a second bending portion 703. One end of the second bending portion 703 is connected to the second riveting portion 701, and the other end is connected to the second locking portion 702. The second bending portion 703 bends toward a second side of the second riveting portion 701, and the second side is in the opposite direction to the first side. Specifically, the second bending portion 703 includes a third bending segment 7031 and a fourth bending segment 7032. The third bending segment 7031 bends relative to the second riveting portion 701, and the fourth bending segment 7032 bends relative to the third bending portion.

[0078] The process of connecting the bed side beam 20 and the headboard 30 using the second connecting assembly 70 is as follows:

[0079] First, connect the second connecting assembly 70 to the bed side beam 20: adjust the distance between the first connecting block 71 and the second connecting block 72 so that the vertical height of the second connecting assembly 70 is less than the inner cavity height of the bed side beam 20. Then, insert the second locking part 702 of the second connecting assembly 70 into the bed side beam 20, aligning the screw hole of the second locking part 702 with the second through hole 212 of the bed side beam 20. Next, pass a bolt through the second through hole 212 and lock it into the screw hole of the second locking part 702. Because the first connecting block 71 and the second connecting block 72 are riveted, during the process of locking the bolt into the screw hole of the second locking part 702, the second riveting part 701 will move towards the inner wall of the bed side beam 20, making the second riveting part 701 tightly adhere to the inner wall of the bed side beam 20, thereby improving the connection strength between the second connecting assembly 70 and the bed side beam 20.

[0080] After completing the connection between the second connecting assembly 70 and the bed side beam 20, the connection between the second connecting assembly 70 and the headboard 30 is then established. Specifically, the locking block 704 on the second connecting assembly 70 is engaged into the locking hole 321 on the vertical support rod 32. When the side wall of the locking hole 321 engages with the locking groove 7041, the limiting block 705 enters the limiting hole, thereby completing the engagement between the second connecting assembly 70 and the headboard 30, as well as the limiting between them.

[0081] In this embodiment, when the vertical support rod 32 of the headboard 30 is relatively high, the bed frame fixing structure also includes a ladder 40, which is connected to the headboard 30 or the side beam 20.

[0082] In this embodiment, the connector 50 is a one-piece molded structure, that is, the connector body 51, the snap-fit ​​block 53, and the snap hook 54 are all one-piece structures. The connecting piece is a one-piece molded structure. The connecting block is a one-piece molded structure.

[0083] In summary, this invention uses a connector 50 to connect the bed slats 10 and the side beams 20, allowing the bed slats 10 to be connected to the side beams 20 via a plug-in connection, making installation more convenient. Simultaneously, the connector 50 is stably connected to the side beams 20 via hooks 54. The bed slats 10 are not simply plugged into the connector 50, but rather, based on this plug-in connection, a stable connection between the bed slats 10 and the connector 50 is achieved through the cooperation of the locking block 53 and the fixing hole 12, thereby realizing a stable connection between the bed slats 10 and the side beams 20. Therefore, the invention achieves a simple, quick, and stable connection between the bed slats 10 and the side beams 20 by using the connector 50, making bed frame installation more convenient.

[0084] Furthermore, for the broken bed side beam 20, the present invention utilizes a first connecting assembly 60 to connect the two side beam units 21. This first connecting assembly 60 consists of two cross-riveted first connecting pieces 61 and second connecting pieces 62. Even after the first connecting assembly 60 is inserted into the side beam unit 21, it still has a certain amount of deformation space. Therefore, when bolts are used for locking, the first hinge portion of the first connecting assembly 60 will move towards and tightly adhere to the inner wall of the side beam unit 21, thereby improving the connection strength between the side beam units 21.

[0085] Similarly, the present invention utilizes a second connecting assembly 70 to connect the bed side beam 20 and the headboard 30. This second connecting assembly 70 consists of two riveted first connecting blocks 71 and second connecting blocks 72. Even after the second connecting assembly 70 is inserted into the bed side beam 20, it still has a certain amount of deformation space. Therefore, when bolts are used for locking, the second hinge portion of the second connecting assembly 70 will move towards and tightly adhere to the inner wall of the bed side beam 20, thereby improving the connection strength between the side beam units 21.

[0086] Therefore, the bed frame of the present invention is easy to install, and the connection is stable and has good connection strength.

[0087] The above description is merely an embodiment of the invention and does not limit the technical scope of the invention. Therefore, any minor modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the invention shall still fall within the scope of the technical solution of the invention.
