[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 bed rail 10 according to an embodiment is shown. The bed rail 10 includes a first end frame 12 and a second end frame 14, and an upper bar member 16 and a lower bar member 18 joined between the first end frame 12 and the second end frame 14. The bed rail 10 includes a height direction H defined by the extending direction of the first end frame 12 or the second end frame 14, a length direction L defined by the direction between the first end frame 12 and the second end frame 14, and a width direction W. The height, length, and width directions are perpendicular to each other.

[0027] refer to Figure 1 and Figure 2 The second end frame 14 includes a second outer member 74, a second upper member 76, a second inner member 78, a third inner member 80, a second lower member 82, a second leg member 84, and a third leg member 86. In this embodiment, the second end frame 14 is shared by the adjacent bed rails 10 and 11.

[0028] The second inner member 78 is closer to the upper member 16 and the lower member 18 than the second outer member 74, and extends along the height direction H between the second upper member 76 and the second lower member 82. The second inner member 78 may be tubular, may be made of a metal such as steel or aluminum, and its cross-section is generally circular. The second outer member 74 is farther away from the upper member 16 and the lower member 18 than the second inner member 78, and extends along the height direction H between the second upper member 76 and the second lower member 82. The third inner member 80 is farther away from the upper member 16 and the lower member 18 than the second outer member 74, and is closer to the bed rail 11 adjacent to the bed rail 10 than the second inner member 78 and the second outer member 74, and extends along the height direction H between the second upper member 76 and the second lower member 82, and its construction is substantially the same as that of the second inner member 78.

[0029] refer to Figure 2-4 The second upper member 76 extends inward along the length direction L from the upper end portion 88 of the second outer member 74 and also extends along the width direction W toward the bed rail 11, thereby forming a substantially vertical first extension member 90 and second extension member 92. The second upper member 76 may be made of, for example, plastic. The first extension member 90 has a third inner connecting tube 96 that receives the upper end portion 94 of the second inner member 78, the second extension member 92 has a fourth inner connecting tube 100 that receives the upper end portion 98 of the third inner member 80, and the second upper member 76 also has a third outer connecting tube 104 that receives the upper end portion 88 of the second outer member 74, the third outer connecting tube 104 being located between the third inner connecting tube 96 and the fourth inner connecting tube 100. The first extension member 90 extends further inward along the length direction L from the upper end portion 94 of the second inner member 78 to form a third inner end portion 106. The third inner end portion 106 includes two latches 108, which can be received in the two locking holes (not shown) of the right latch 110 of the upper rod member 16. The second extension member 92 extends further along the width direction W from the upper end portion 98 of the third inner member 80 to form a fourth inner end portion 114. The fourth inner end portion 114 includes two latches 116, which can be received in the two locking holes (not shown) of the left latch 45 of the upper rod member 17 of the bed rail 11. It should be understood that the latches and locking holes are only one embodiment of the detachable connection, and those skilled in the art can replace them with other detachable connection methods as needed. This application also includes other embodiments below ( Figure 6-10 Another specific implementation of the detachable connection is provided in ().

[0030] The second lower member 82 extends inward along the length direction L and simultaneously along the width direction W from the lower end portion 118 of the second outer member 74, thereby forming a substantially perpendicular third extension member 120 and a fourth extension member 122. The second lower member 82 may be made of materials such as plastic. The third extension member 120 has a fifth inner connecting tube 126 that receives the lower end portion 124 of the second inner member 78, and the fourth extension member 122 has a sixth inner connecting tube 130 that receives the lower end portion 128 of the third inner member 80. The second lower member 82 also has a fourth outer connecting tube 134 that receives the lower end portion 118 of the second outer member 74, and the fourth outer connecting tube 134 is located between the fifth inner connecting tube 126 and the sixth inner connecting tube 130. The third extension member 120 extends further inward along the length direction L from the lower end portion 124 of the second inner member 78 to form a fifth inner end portion 136. The fifth inner end portion 136 includes two second holes 138, which can receive the second pin 142 of the right end portion 140 of the lower rod member 18. The second pin 142 can be, for example, a V-shaped spring ball. The fourth extension member 122 extends further along the width direction W from the lower end portion 128 of the third inner member 80 to form a sixth inner end portion 144. The sixth inner end portion 144 includes two third holes 146, which can receive the two first pins 63 of the left end portion 61 of the lower rod member 19 of the bed rail 11. It should be understood that the pins and holes are only one embodiment of the detachable connection, and those skilled in the art can replace them with other detachable connection methods as needed. It should be understood that the lower rod member 18 can also be non-detachably connected to the second lower member 82.

[0031] The second outer member 74 is located away from the upper bar member 16 and lower bar member 18 of the bed rail 10 relative to the second inner member 78, and away from the upper bar member 17 and lower bar member 19 of the bed rail 11 relative to the third inner member 80. It extends along the height direction H between the second upper member 76 and the second lower member 82. The second outer member 74 may be tubular and may be made of a metal such as steel or aluminum.

[0032] The bottom of the fourth outer connecting pipe 134 of the second lower member 82 has sleeves 152 and 154 extending upward and downward along the height direction H, wherein sleeve 152 is substantially located in the length direction L of the bed rail 10, and sleeve 154 is substantially located in the width direction W of the bed rail 10. When the lower end portion 118 of the second outer member 74 is received by the fourth outer connecting pipe 134, the portions of sleeves 152 and 154 above the fourth outer connecting pipe 134 are accommodated within the second outer member 74.

[0033] The vertical portion 156 of the second support member 84, extending along the height direction H, passes through the sleeve 152 below the fourth outer connecting tube 134 and is at least partially accommodated within the sleeve 152. The horizontal portion 158 of the second support member 84 rests under the mattress or is fixed to the bed board. The vertical portion 160 of the third support member 86, extending along the height direction H, passes through the sleeve 154 below the fourth outer connecting tube 134 and is at least partially accommodated within the sleeve 154. The horizontal portion 162 of the third support member 86 rests under the mattress or is fixed to the bed board.

[0034] Several through holes (not shown) are arranged from high to low on the vertical portion 156 of the second support member 84. The sleeve 152, located below the fourth external connecting pipe 134, has a first pin hole 164 on its pipe wall corresponding to the through holes. A first latch 166 is located below the second lower member 82 and has a first pin 168 extending along the length direction L and capable of telescopic sliding. The first pin 168 passes through the first pin hole 164 and can telescopically slide into or out of the through hole on the second support member 84, thereby selectively fixing the second lower member 82 at a certain height position on the second support member 84. The first latch 166 also includes a first push button 170 fixedly connected to the first pin 168. The first push button 170 is mounted on a push button seat 172, which has a first positioning hole 174 and a second positioning hole 176. The first push button 170 has a positioning protrusion 178. When the positioning protrusion 178 engages with the first positioning hole 174, the first pin 168 is positioned away from the through hole on the second leg member 84. At this time, the vertical portion 156 of the second leg member 84 and the sleeve 152 can be slidably adjusted in position. When the first pin hole 164 is opposite to a through hole at a certain height and the positioning protrusion 178 engages with the second positioning hole 176, the first pin 168 is positioned into the through hole on the second leg member 84, thereby fixing the second lower member 82 at that height position of the second leg member 84.

[0035] A number of through holes (not shown) are arranged from high to low on the vertical portion 160 of the third leg member 86. The sleeve 154 has a second pin hole (not shown) on the tube wall of the portion below the fourth external connecting tube 134, which corresponds to the through holes. The second latch 182 is located below the second lower member 82 and has a second pin 184 that extends along the length direction L and is telescopically slidable. The second pin 184 passes through the second pin hole and can telescopically slide into or out of the through hole on the third leg member 86, thereby selectively fixing the second lower member 82 at a certain height position of the third leg member 86. The second latch 182 also includes a button 186 and a button base 188. The button 186 has an extension arm 190 with a proximal end near the button 186 and a distal end opposite it. The proximal end of the extension arm 190 is pivotally connected to the button base 188 via a pivot axis 191 extending in the height direction. The distal end of the extension arm 190 is fixedly connected to a second pin 184, such that the extension arm 190 can be pivoted about the pivot axis 191 (similar to a seesaw) by the button 186, thereby moving the second pin 184. A first spring (not shown) abuts between the button 186 and the button base 188, and the first spring biases the second pin 184 into a position where it enters a through hole in the third leg member 86. When the button 186 is pressed down against the biasing force of the first spring, the second pin 184 moves and leaves the through hole in the third leg member 86, at which point the vertical portion 160 of the third leg member 86 and the sleeve 154 can be slidably adjusted in position. When the second pin hole 180 is opposite to the through hole at a certain height and the first spring biases the second pin 184 to the position where it enters the through hole on the third leg member 86, the second lower member 82 is fixed at that height position of the third leg member 86.

[0036] Understandably, the through holes of the second leg member 84 and the third leg member 86 are set at the same height. When the horizontal portions of the second leg member 84 and the third leg member 86 are pressed under the mattress, the second leg member 84 and the third leg member 86 are relatively fixed. Then, after unlocking the first latch 166 and the second latch 182, the height of the second lower member 82 relative to the mattress can be adjusted by raising or lowering it, and the height of the entire second end frame 14 relative to the mattress can be adjusted accordingly. The first latch 166 and the second latch 182 employ a positioning lock (i.e., can be positioned in both locked and unlocked positions) and an offset lock (i.e., always offset in the locked position), respectively, which makes operation more convenient and safer. When adjustment is required, first unlock the first latch 166 and position it in the unlocked position. Then, support the second lower component 82 (or other support points on the bed rail 10 or 11, such as the lower bar component 18 of the bed rail 10) with one hand, and unlock the second latch 182 with the other hand. Then, when raising or lowering the second lower component 82 to the desired height, release the hand pressing the button 186 on the second latch 182 to quickly lock it in position. Finally, lock the first latch 166 and position it in the locked position. It is understood that in other embodiments, two first latches 166 or two second latches 182 may also be used.

[0037] The first end frame 12 can be configured with a structure such as the first latch 166 or the second latch 182 to adjust the height between the first end frame 12 and the mattress, which will not be described in detail here. It should be understood that when adjusting the height of the bed rail 10, since the first end frame 12 and the second end frame 14 of the bed rail 10 can have different heights to a certain extent, one side can be adjusted first and then the other side can be adjusted.

[0038] refer to Figure 5 Preferably, the horizontal portion 158 of the second leg member 84 and the horizontal portion 162 of the third leg member 86 are configured to extend at approximately a 45-degree angle to the length direction L of the bed rail 10, such that the horizontal portion 158 of the second leg member 84 and the horizontal portion 162 of the third leg member 86 are substantially parallel.

[0039] The leg extension plate 194 engages with the free ends of both the horizontal portion 158 of the second leg member 84 and the horizontal portion 162 of the third leg member 86. Specifically, the leg extension plate 194 includes a flat body 196 and two connectors 198 extending substantially parallel to the sides of the body 196. The spacing between the two connectors 198 is substantially the same as the spacing between the horizontal portions 158 and 162 when the bed rails 10 and 11 are arranged adjacent to each other. The two connectors 198 can be accommodated in the free ends of the horizontal portions 158 and 162, respectively, thereby securing the leg extension plate 194 to the second leg member 84 and the third leg member 86. It should be understood that a plug-in groove can also be provided on the side of the main body 196 of the support extension plate 194, and the free ends of the horizontal portions 158 and 162 can be inserted and accommodated in the plug-in groove to fix the support extension plate 194 to the second support member 84 and the third support member 86. In this embodiment, the main body 196 is semi-circular, and the two plug-in joints 194 are provided on the side of the straight edge. The support extension plate 194 increases the contact area between the support member and the mattress, providing better support for the bed rail and effectively preventing the bed rail from tipping over under force.

[0040] refer to Figure 6-10 This provides another embodiment of the locking connection between the right latch 110 and the second upper member 76. Specifically, the third inner end portion 106 of the first extension member 90 includes a locking groove 200, and the right latch 110 of the upper member 16 includes a locking pin 202 that extends and slides telescopically along the length direction L of the bed rail 10. When the upper member 16 is located in a position where the locking pin 202 faces the locking groove 200, the locking pin 202 can slide into or out of the locking groove 200, thereby locking or releasing the right latch 110 and the third inner end portion 106. The outer end of the right latch 110 has an open groove 204 with the opening of the open groove 204 facing upward, and the locking pin 202 is located within the open groove 204. The lock groove 200 is provided on the lock groove body 206 that engages with the third inner end portion 106. The lock groove body 206 can be received in the open groove 204, and when the lock groove body 206 is received in the open groove 204, the lock pin 202 faces the lock groove 200 and can slide into the lock groove 200.

[0041] The right latch 110 includes a housing 111, an unlocking assembly, and a second spring 209. When the upper lever member 16 is positioned with the locking pin 202 facing the lock groove 200, the unlocking assembly can drive the locking pin 202 away from the lock groove 200, and the second spring 209 can bias the locking pin 202 into the lock groove 200. The unlocking assembly includes a first unlocking member 210, a second unlocking member 212, a drive lever 214, and a third spring 216.

[0042] The second unlocking member 212 includes a pressing portion 218 exposed outside the housing 111 and an extension portion 220 assembled inside the housing 111. In this embodiment, the pressing portion 218 is located below the right latch 110, and the extension portion 220 extends upward from the pressing portion 218, but its position can be adjusted as needed. The extension portion 220 has an oblique groove 222 extending through the width direction W, and the oblique groove 222 extends outward along the length direction L (i.e., the extension direction of the locking pin 202) and upward along the height direction H. The locking pin 202 includes a transverse groove 224 extending through the width direction W and a vertical groove 226 extending through the height direction H, and the transverse groove 224 and the vertical groove 226 intersect and communicate with each other. The extension portion 220 passes through the vertical groove 226 from bottom to top, and during assembly, the oblique groove 222 is positioned at the intersection with the transverse groove 224. The drive rod 214 passes through the portion where the transverse groove 224 and the oblique groove 222 intersect and connect along the width direction, and can move in the length direction L. The housing 111 only needs to prevent the drive rod 214 from disengaging from the transverse groove 224. Figure 8 As shown, under no external force, the uppermost end of the inclined groove 222 intersects the innermost end of the transverse groove 224, and the drive rod 214 is located at the first position of this intersection. When an external force is applied upward to the pressing part 218, the inclined groove 222 will move vertically upward along the height direction H. During the upward movement of the inclined groove 222, it will push the drive rod 214 to move inward along the length direction L. During the inward movement of the drive rod 214, it will push the locking pin 202 to move inward along the length direction L, thereby causing the locking pin 202 to disengage from the locking groove 200. At this time, as... Figure 9 As shown, the second spring 209 is compressed by the external force, and the lowermost end of the oblique groove 222 intersects the innermost end of the transverse groove 224. The drive rod 214 is located at the second position of this intersection, and the first position is closer to the protruding side of the locking pin 202 than the second position. When the external force is removed, the biasing force of the second spring 209 will cause the locking pin 202 to move outward along the length direction. During the outward movement of the locking pin 202, it will push the drive rod 214 to move outward along the length direction. During the outward movement of the drive rod 214, it will push the second unlocking member 212 to move downward, ultimately as shown. Figure 8 As shown, the locking pin 202 moves to enter the locking groove 200, the oblique groove 222 moves downward to the uppermost end to intersect with the innermost end of the transverse groove 224, and the drive rod 214 moves to the first position.

[0043] The first unlocking member 210 includes a push button portion 228 exposed outside the housing 111 and a push rod portion 230 assembled inside the housing 111. In this embodiment, the push button portion 228 is located above the right latch 110, and the push rod portion 230 extends downward from the push button portion 228, but its position can be adjusted as needed. One end of the third spring 216 abuts against one side of the push rod portion 230 along its length direction L, and the other end can abut against the housing 111 or other components having a fixed position in the length direction. The third spring 216 is used to bias the first unlocking member 210 at a position where the push rod portion 230 abuts against the extension portion 220 of the second unlocking member 212 (or to bias the first unlocking member 210 at a position where the push rod portion 230 is above the extension portion 220 of the second unlocking member 212), thereby preventing the second unlocking member 212 from moving upward (e.g., Figure 8 As shown), pushing the push button portion 228 can overcome the biasing force of the third spring 216, causing the push rod portion 230 to move along the length direction L, thereby misaligning the push rod portion 230 with the extension portion 220, thus allowing the second unlocking member 212 to move upward (as shown). Figure 9 (As shown). Without external force, the first unlocking member 210 will prevent the second unlocking member 212 from unlocking. The right latch 110 can only be unlocked by operating the first unlocking member 210 and the second unlocking member 212 simultaneously, which increases security.

[0044] 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.
