[0010] In a second embodiment, this application provides a support assembly for being disposed under a mattress and connected to a bed rail on the side of the mattress, the bed rail having a horizontal support leg located under the mattress. The support assembly comprises: four support connectors, at least one of which is connected to the bed rail via the horizontal support leg; and four bottom support rods, each of which is connected between two adjacent support connectors to form a quadrilateral frame structure.

[0011] As described above, the support assembly is configured to connect to a first bed rail and a second bed rail located on two adjacent sides of the mattress, wherein the first bed rail and the second bed rail have at least one horizontal support foot at their adjacent points, and each of the first bed rail and the second bed rail has another horizontal support foot at one end away from the adjacent point. A first of four support connectors is connected to the two bed rails via the horizontal support foot at the adjacent point, a second of four support connectors is connected to the first bed rail via the horizontal support foot of the first bed rail away from the adjacent point, and a third of four support connectors is connected to the second bed rail via the horizontal support foot of the second bed rail away from the adjacent point. The second and third of the four support connectors are located on either side of the first of the four support connectors.

[0012] As described above, the support assembly is configured to connect to a third and a fourth bed rail located on two opposite sides of the mattress, wherein the third bed rail has two horizontal support legs at its two ends, and the fourth bed rail has two horizontal support legs at its two ends. Two adjacent of the four support connectors are each connected to the third bed rail via the two horizontal support legs of the third bed rail, and the other two adjacent of the four support connectors are each connected to the fourth bed rail via the two horizontal support legs of the fourth bed rail.

[0013] As described above, the support assembly is configured to connect to a fifth, sixth, and seventh bed rail located on three sides of the mattress, wherein the sixth bed rail is located between the fifth and seventh bed rails. The fifth and sixth bed rails have at least one horizontal support foot at a first adjacent point, and the sixth and seventh bed rails have at least one horizontal support foot at a second adjacent point. The fifth bed rail has another horizontal support foot at its end away from the first adjacent point, and the seventh bed rail has another horizontal support foot at its end away from the second adjacent point.

[0016] The support connector and support assembly of this application have many advantages over the prior art, such as higher safety, which can prevent the bed rail from shaking significantly under stress. Attached Figure Description

[0025] In the following description, different embodiments of this application will be described. Specific structures and details are presented for illustrative purposes to provide a thorough understanding of the embodiments. However, it will be apparent to those skilled in the art that this application can be implemented without these specific details. Furthermore, well-known features will be omitted or simplified to make the described embodiments clear.

[0026] Referring now to the accompanying drawings, in which the same reference numerals denote the same parts in several views. Figure 1 A perspective view of a bed guardrail system according to an embodiment is shown, the bed guardrail system including a support connector 10. Further reference... Figure 2 and Figure 3 The support connector 10 includes a connecting end 12 and a connecting end 14. The connecting end 12 includes two horizontally parallel insertion tubes 16 and 18 with openings facing the same direction. The insertion tube 16 is sized and shaped to receive the proximal end of the horizontal support foot 22 of one bed rail 20, and the insertion tube 18 is sized and shaped to receive the proximal end of the horizontal support foot 26 of another bed rail 24, wherein the bed rail 20 and the bed rail 24 are arranged adjacent to each other at a 90-degree angle.

[0027] Connector 16 and connector 18 are spaced apart. The tops of connector 16 and connector 18 are connected via a top web 28, and the bottoms of connector 16 and connector 18 are connected via a bottom web 30. The top of connector 16 has a through hole 32 for a resilient pin provided on the horizontal support leg 22 to extend out, thereby achieving a locking connection between the horizontal support leg 22 and connector 16. Similarly, the top of connector 18 has a through hole 34 for a resilient pin provided on the horizontal support leg 26 to extend out.

[0028] The connecting end 14 extends substantially in the opposite direction to the connecting end 12. The connecting end 14 includes a top plate 36 and a bottom plate 38. The top plate 36 is substantially flush with the top web plate 28, and the bottom plate 38 is substantially flush with the bottom web plate 30. A partition 40 vertically connects the top plate 36 and the bottom plate 38, thereby dividing the connecting end 14 into two adjacent transition portions 42 and 44. The partition 40 is substantially located in the middle of the top plate 36 and the bottom plate 38, so that the transition portions 42 and 44 are symmetrically arranged in the horizontal direction, wherein the transition portion 42 is located on the side closer to the insertion tube 16, and the transition portion 44 is located on the side closer to the insertion tube 18.

[0029] In this embodiment, the adapter 42 and adapter 44 are configured to have rotating cavities. The rotating cavity of adapter 42 can receive one end of the bottom support rod 46, and the rotating cavity of adapter 44 can receive one end of the bottom support rod 48. Adapter 42 has two shaft holes 50 disposed opposite to the top plate 36 and the bottom plate 38, and a rotating shaft (not shown) is disposed between the two shaft holes 50. One end of the bottom support rod 46, received in adapter 42, is connected to the rotating shaft, thereby achieving a rotatable connection between the bottom support rod 46 and adapter 42. It can be understood that the insertion tube 16, insertion tube 18, adapter 42, and adapter 44 are generally located in a plane, and the rotation axis S1 of the bottom support rod 46 and adapter 42 extends along the axial direction of the rotating shaft and is substantially perpendicular to this plane. With substantially the same arrangement, the bottom support rod 48 is rotatably connected to adapter 44.

[0030] The connecting end 14 also includes two limiting plates 54 and 56 connecting the top plate 36 and the bottom plate 38 on both sides of the connecting end 14. The limiting plate 54, alone or together with the partition plate 40 (if provided), limits the rotation range of the bottom support rod 46, and the limiting plate 56, alone or together with the partition plate 40 (if provided), limits the rotation range of the bottom support rod 48. Optionally, the above-mentioned rotation range can be an angle of 45 degrees, but it can also be an angle greater than 45 degrees. In normal use, the bottom support rod 46 and the bottom support rod 48 are positioned at an angle of 90 degrees between their longitudinal extension directions F1 and F2, and at an angle of 135 degrees between their longitudinal extension directions and the longitudinal extension direction F3 of the insertion tube 16 or the insertion tube 18.

[0031] When the horizontal support legs 22, 26, support connector 10, bottom support rod 46, and bottom support rod 48 are connected, they form a roughly "Y"-shaped assembly. The longitudinal extension direction F1 of the bottom support rod 46 is basically parallel to the length direction L1 of the bed rail 20, and the longitudinal extension direction of the bottom support rod 48 is basically parallel to the length direction L2 of the bed rail 24. When in use, this "Y"-shaped assembly is pressed under the mattress (not shown in the figure), which can improve the stability of the bed rail or the entire bed rail system.

[0032] It should be understood that the support connector 10 may not have a connector 16 or connector 18, that is, the support connector 10 may have only one connector. In this case, there are several possible implementation methods: 1. Only one of the bed rails 20 and 24 has a horizontal support leg, which is received in the aforementioned connector; 2. The bed rails 20 and 24 share a horizontal support leg, which is received in the aforementioned connector; 3. There is only one bed rail 20 or only one bed rail 24.

[0033] It should be understood that the connecting end 12 may be without the top web 28 and the bottom web 30, or the insertion tube 16 and the insertion tube 18 may be connected by a web located in the middle of the two.

[0034] It should be understood that the insertion pipe 16 and the insertion pipe 18 can also be arranged adjacent to each other, that is, the insertion pipe 16 and the insertion pipe 18 can share a part of the side wall. In this case, the connecting end 12 may not have the top web plate 28 and the bottom web plate 30.

[0035] It should be understood that the support connector 10 may be without the partition 40, meaning that the transition part 42 and the transition part 44 are connected. The partition 40 can serve as a limiting element and increase the strength of the support connector 10.

[0036] It should be understood that adapters 42 and 44 can also be replaced by two connectors, the size and shape of which are designed to receive one end of the bottom support rod 46 and one end of the bottom support rod 48, respectively. The angle between the longitudinal extension directions of the two connectors is 90 degrees, and the angle between the longitudinal extension directions of the two connectors and the longitudinal extension direction of connector 16 or connector 18 is 135 degrees. This allows the assembly to form a roughly "Y" shape when the horizontal support foot 22, horizontal support foot 26, support connector 10, bottom support rod 46, and bottom support rod 48 are fully connected.

[0037] Figure 4A support connector 60 of a bed rail system according to an embodiment is shown. The support connector 60 includes a connecting end 62 and a connecting end 64. The connecting end 64 is substantially the same as the connecting end 14 of the support connector 10 (a preferred embodiment or alternative embodiment of the connecting end 14 may be applied to the connecting end 64), the difference between the support connector 60 and the support connector 10 is that the connecting end 62 includes two horizontally non-parallel insertion tubes 66 and 68, such that their openings face different directions. The insertion tube 66 is sized and shaped to receive the proximal end of a horizontal support foot 72 of a bed rail 70, and the insertion tube 68 is sized and shaped to receive the proximal end of a bottom support extension 74.

[0038] The top of the connector 66 is substantially flush with the top of the connector 68, and the bottom of the connector 66 is substantially flush with the bottom of the connector 68. The longitudinal extension direction F4 of the connector 66 and the longitudinal extension direction F5 of the connector 68 form an angle, preferably equal to 45 degrees, but the angle may be less than or greater than 45 degrees. Understandably, the size of the angle is related to the extension direction of the proximal end of the horizontal support leg 72. For example, when the proximal end of the horizontal support leg 72 extends in a direction perpendicular to the connector 68, the angle may be 90 degrees.

[0039] Bottom support rods 76 and 78 are rotatably connected to connecting end 64. When the horizontal support foot 72, bottom support extension 74, support connector 60, bottom support rod 76, and bottom support rod 78 are connected, an approximately "X"-shaped assembly is formed. The longitudinal extension direction F6 of bottom support rod 76 and bottom support extension 74 is basically parallel to the length direction L3 of bed rail 70, and the longitudinal extension direction F7 of bottom support rod 78 is basically perpendicular to the length direction L3 of bed rail 70. When in use, the "X"-shaped assembly is pressed under the mattress (not shown in the figure), which can improve the stability of the bed rail or the entire bed rail system.

[0040] Preferably, the longitudinal extension direction of the bottom support extension 74 overlaps with the longitudinal extension direction of the bottom support rod 76. Preferably, the distal end of the bottom support extension 74 also includes a vertical plate 80 extending upward in a vertical direction, and the dimensions of the bottom support extension 74 are designed such that when the connection is completed, the vertical plate 80 is located on the side of the mattress and abuts against the side of the mattress, which can further improve the stability of the bed rail or the overall bed rail system.

[0041] It should be understood that the connector 68 can also be used to receive the horizontal support leg of another bed rail (not shown) located adjacent to the bed rail 70.

[0042] Figure 5A support assembly 90 of a bed rail system according to an embodiment is shown. The support assembly 90 includes two support connectors 10, two support connectors 60, a bottom support rod 46, a bottom support rod 48, a bottom support rod 76, and a bottom support rod 78. The bottom support rod 46 connects one of the support connectors 10 and one of the support connectors 60; the bottom support rod 48 connects two of the support connectors 10; the bottom support rod 76 connects the other support connector 10 and the other support connector 60; and the bottom support rod 78 connects two of the support connectors 60, thereby forming a quadrilateral shape, with the bottom support rods 46, 48, 76, and 78 forming the four sides of this quadrilateral.

[0043] In its active or unfolded state, the support assembly 90 is generally in a single plane (the plane of the support assembly 90 described below refers to the active or unfolded state of the support assembly 90). In use, the connection between the bottom support rod and the support connector is rotated (as can be seen from the above embodiments, the rotation axis of the bottom support rod and the support connector is substantially perpendicular to the plane where the support assembly 90 is located), making the support assembly 90 approximately rectangular. Then, the horizontal support legs (e.g., horizontal support legs 22, 26, and 72) of one or more bed rails (e.g., bed rails 20, 24, and 70 in the above embodiments) are connected to the support connectors (e.g., support connectors 10 and 60), so that the bed rails are substantially parallel to the bottom support rods (e.g., bottom support rods 46, 48, 76, and 78), and the bed rails are substantially perpendicular to the plane where the support assembly 90 is located. When the mattress is placed on top of the support assembly 90, the bed rails are located and abut against the side of the mattress. The support component 90 enhances the protective stability and reliability of the bed rails to which it is connected.

[0044] It should be understood that when the bottom support rod is connected to the support connector in a detachable plug-in manner, the bottom support rod and the support connector are connected in the quadrilateral connection manner described above, so that the support assembly 90 is approximately rectangular.

[0045] Preferably, at least two opposing bottom support rods (e.g., bottom support rod 46 and bottom support rod 76, or bottom support rod 48 and bottom support rod 78) are designed to have variable lengths. This variable length allows the support assembly 90 to adjust its overall size to fit beds of different sizes, or allows the support assembly 90 to have a smaller size than in its usable state, thus facilitating storage, packaging, or transportation.

[0046] In this embodiment, the bottom support rod 46 includes two sub-rods 92 and a connecting seat 94 connecting the two sub-rods 92. The proximal ends of the two sub-rods 92 are respectively connected to the two ends of the connecting seat 94 via rotating shafts (not shown in the figure), so that the two sub-rods 92 can rotate about a rotation axis S2 that extends axially along their respective rotating axes, is perpendicular to the bottom support rod 46 and parallel to the plane where the support assembly 90 is located. The distal ends of the two sub-rods 92 are respectively connected to the support connector 10 and the support connector 60 (refer to the above embodiment). Similarly, the bottom support rod 76 has a configuration that is basically the same as the bottom support rod 46, and its two sub-rods can rotate about the same rotation axis as the two sub-rods 92 of the bottom support rod 46. With this configuration, the portion of the support assembly 90 located on one side of the connecting seat 94 can be folded to the other side of the connecting seat 94 (e.g., Figure 6 As shown), thereby reducing the size of the support assembly 90 along the longitudinal extension direction of the bottom support rod 46 or the bottom support rod 76 by folding.

[0047] In this embodiment, the bottom support rod 48 includes two sub-rods 96 and a connecting seat 98 connecting the two sub-rods 96. The proximal ends of the two sub-rods 96 are connected to the two ends of the connecting seat 98 via rotating shafts (not shown in the figure), so that the two sub-rods 96 can rotate about a rotation axis S3 that extends axially along their respective rotation axes and is perpendicular to the plane where the support assembly 90 is located. The distal ends of the two sub-rods 96 are connected to two support connectors 10 respectively (refer to the above embodiment). Similarly, the bottom support rod 78 has a configuration that is substantially the same as the bottom support rod 48, and its two sub-rods can rotate about a rotation axis that is perpendicular to the plane where the support assembly 90 is located. With this configuration, the portion of the support assembly 90 located on one side of the connecting seat 98 (specifically one of the sub-rods 96) can be folded to the other side of the connecting seat 98 (specifically the other sub-rod 96), thereby reducing the size of the support assembly 90 along the longitudinal extension direction of the bottom support rod 48 or the bottom support rod 78 by folding. Preferably, the bottom support rod 48 and the bottom support rod 78 are configured such that when folded, the connecting seats of both move toward the center of the support assembly 90 (e.g., Figure 7 As shown), this will not increase the dimension of the support assembly 90 along the longitudinal extension direction of the bottom support rod 46 or the bottom support rod 76 after folding.

[0048] In this embodiment of the application, the bottom support rod 46 and the bottom support rod 76 can be folded after the bottom support rod 46 and the bottom support rod 76 are folded, and vice versa.

[0049] It should be understood that the support component 90 may be provided with a folding connection only on the bottom support rod 46 and the bottom support rod 76, or only on the bottom support rod 48 and the bottom support rod 78, or as shown in the embodiments of this application, may be provided with a folding connection on both the bottom support rod 46 and the bottom support rod 76, and the bottom support rod 48 and the bottom support rod 78.

[0050] It should be understood that the folding method of connecting two sub-rods with a connecting seat can be replaced by a telescopic connection of two sub-rods. Specifically, both sub-rods are tubular, and one sub-rod is housed within the other, thereby allowing the size of the bottom support rod to be adjusted by telescopic adjustment.

[0051] It should be understood that a telescopic connection can be provided only for bottom support rods 46 and 76, or only for bottom support rods 48 and 78, or simultaneously for both bottom support rods 46 and 76, and bottom support rods 48 and 78, or even for bottom support rods 46 and 76 and bottom support rods 48 and 78, and vice versa.

[0052] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
