[0040] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are some embodiments of this utility model, not all embodiments.

[0041] Reference Figures 1 to 7 As shown, the folding bedside frame includes a support frame 100, a hinge seat 200, an armrest frame 300, a locking seat 400, an elastic element 500, and a connecting rod 600.

[0042] Reference Figures 1 to 3 As shown, the support frame 100 includes a main frame 110, a vertical support member 120, and a horizontal support member 130.

[0043] The main frame 110 includes two support tubes arranged in the vertical direction and a connecting tube arranged in the horizontal direction. The left and right ends of the connecting tube are respectively connected to the middle of the two support tubes. The main frame 110 is H-shaped. Each support tube has a first connecting hole that runs through in the horizontal direction at the bottom and a second connecting hole that runs through in the horizontal direction at the top.

[0044] There are two vertical support members 120. Each vertical support member 120 has a downward-through mounting hole at its top. The vertical support member 120 is fitted onto the bottom of the support tube through the mounting hole. The two vertical support members 120 are slidably fitted onto the bottom of the two support tubes respectively. Each vertical support member 120 has multiple first pin holes spaced apart in the vertical direction on its side wall. The first pin holes are connected to the mounting hole. A first pin is inserted into the first connecting hole of the support tube after passing through any one of the first pin holes, thus fixing the position of the vertical support member 120 relative to the support tube. Each vertical support member 120 has a support pad at its bottom, which is used to abut against the ground. Therefore, since the support pad at the bottom of the vertical support member 120 abuts against the ground, by removing the first pin and adjusting the position of the vertical support member 120 in the vertical direction so that one of the first pin holes is aligned with the first connecting hole, and then inserting the first pin through the first pin hole into the first connecting hole, the height of the main frame 110 relative to the ground can be adjusted.

[0045] The transverse support 130 includes a support frame extending in the front-to-back direction and two mounting tubes. The two mounting tubes are connected to the rear side of the support frame and are arranged vertically. The two mounting tubes are respectively fitted onto the outside of the two support tubes of the main frame 110. The transverse support 130 is located above the transverse tubes of the main frame 110. The support frame extends forward of the main frame 110 so that the support frame can be inserted under the mattress of the nursing bed. The mattress and the bed board clamp the support frame to keep it horizontal, so that the transverse support 130 provides transverse support to the main frame 110 and keeps the main frame 110 upright without tilting forward or backward.

[0046] Reference Figures 4 to 7 As shown, two hinge seats 200 are respectively installed on the top of the two support tubes of the main frame 110. Specifically, each hinge seat 200 has an assembly hole at its bottom and a through second pin hole on the side wall of the assembly hole. The assembly hole is fitted onto the top of the support tube, and the second pin is inserted into the second connecting hole after passing through the second pin hole, so that the hinge seat 200 is installed on the top of the support tube.

[0047] Each hinge seat 200 extends rearward to the rear of the support tube of the main frame 110, and each hinge seat 200 is provided with a shaft hole that runs through in the left-right direction, the shaft hole being located behind the support tube of the main frame 110.

[0048] Reference Figure 4 As shown, each hinge seat 200 is provided with a locking hole 210 at its top, and each hinge seat 200 is also provided with a guide groove 220 at its top. The guide groove 220 extends from the locking hole 210 through the hinge seat 200 to the rear. The guide groove 220 gradually slopes downward from front to back, and the width of the guide groove 220 in the left-right direction is greater than the width of the locking hole 210 in the left-right direction.

[0049] Each hinge seat 200 has a stop 230 on its left or right side wall, and the stop 230 is offset from the support tube of the main frame 110 in the left-right direction.

[0050] Reference Figures 1 to 4 As shown, the handrail frame 300 includes a main body 301, a hinge shaft 310, a hinge tube 320, two horizontal handrails 330, two horizontal locking members 331, a vertical handrail 340, and a vertical locking member 341.

[0051] Two horizontal tubes 302 are provided in the middle of the main body 301. The two horizontal tubes 302 are distributed in parallel vertically and each horizontal tube 302 runs through the left and right directions. A vertical tube 303 is provided at the top of the main body 301 and runs through the top of the main body 301.

[0052] Reference Figure 1 and Figure 3 As shown, two horizontal handrails 330 are respectively arranged on the left and right sides of the main body 301. The horizontal handrails 330 are provided with two horizontal insertion tubes extending in the left and right directions. The two horizontal insertion tubes are arranged in parallel vertically. A C-shaped connecting tube is provided between the two horizontal insertion tubes. The two horizontal insertion tubes are respectively inserted into the two horizontal tubes 302. The side wall of the upper horizontal insertion tube is provided with multiple third pin holes. The side wall of the upper horizontal tube 302 is provided with a through third connecting hole. The horizontal locking member 331 includes a third pin and a C-shaped clip provided on the head of the third pin. After the third pin passes through the third connecting hole, it is inserted into any one of the third pin holes, so that the horizontal insertion tube is fixed in the left and right direction relative to the horizontal tube 302. The arc shape of the C-shaped clip matches the shape of the outer side wall of the horizontal tube 302. The C-shaped clip can be locked on the outer side wall of the horizontal tube 302.

[0053] By disassembling the transverse locking member 331, the transverse handrail 330 can be adjusted in the left and right direction relative to the main body 301. Then, one of the third pin holes is aligned with the third connecting hole. The third pin of the transverse locking member 331 is then inserted into the third pin hole after passing through the third connecting hole, thereby fixing the position of the transverse handrail 330.

[0054] The position of the horizontal handrail 330 can be adjusted at any time according to the needs of bedridden users, and the length of the handrail frame 300 in the left and right directions can be changed to adapt to the usage needs of different bedridden users.

[0055] Reference Figures 1 to 3 As shown, the bottom of the vertical handrail 340 is provided with a vertical insertion tube extending in the vertical direction. The vertical insertion tube is inserted into the vertical tube 303. The side wall of the vertical insertion tube is provided with multiple fourth pin holes. The vertical tube 303 is provided with a fourth connecting hole. The vertical locking member 341 includes a fourth pin and a C-shaped clip provided on the head of the fourth pin. After the fourth pin passes through the fourth connecting hole, it is inserted into any one of the fourth pin holes, so that the vertical insertion tube is fixed in the vertical direction relative to the vertical tube 303. The arc shape of the C-shaped clip matches the shape of the outer side wall of the vertical tube 303. The C-shaped clip can be locked on the outer side wall of the vertical tube 303.

[0056] By disassembling the vertical locking member 341, the vertical handrail 340 can be adjusted in the vertical direction relative to the main body 301. Then, one of the fourth pin holes is aligned with the fourth connecting hole. The fourth pin of the vertical locking member 341 is then inserted into the fourth pin hole after passing through the fourth connecting hole, thereby fixing the position of the vertical handrail 340.

[0057] The position of the vertical handrail 340 can be adjusted at any time according to the needs of bedridden users, and the height of the handrail frame 300 in the vertical direction can be changed to adapt to the usage needs of different bedridden users.

[0058] Reference Figures 4 to 7 As shown, the bottom of the main body 301 is provided with two hinge tubes 320 spaced apart from left to right. The bottom of each hinge tube 320 is provided with a hinge shaft 310 arranged in the left-right direction. The two hinge shafts 310 are respectively inserted into the shaft holes of the two hinge seats 200, so that the handrail frame 300 can rotate around the hinge shaft 310. The hinge tubes 320 and the support tubes of the main frame 110 are staggered in the left-right direction. The stop block 230 of the hinge seat 200 is located in front of the hinge tube 320. When the handrail frame 300 rotates upward to the vertical state, the stop block 230 abuts against the front side of the hinge tube 320.

[0059] Two locking seats 400 are respectively installed on two hinge tubes 320. Each locking seat 400 is provided with a sliding hole that runs through the vertical direction. The sliding hole is fitted onto the outside of the hinge tube 320. The side wall of the hinge tube 320 is provided with a sliding groove 321 that runs through the horizontal direction. The side wall of the sliding hole is provided with a through hole that runs through the horizontal direction. The slider 420 passes through the through hole and the sliding hole and extends into the sliding groove 321, thereby allowing the locking seat 400 to slide up and down relative to the hinge tube 320. The slider 420 and the sliding groove 321 cooperate to limit the stroke of the locking seat 400 sliding up and down.

[0060] Two elastic elements 500 are respectively disposed inside the hinge tube 320, and each elastic element 500 is a tension spring. Taking one of the elastic elements 500 as an example, the top end of the elastic element 500 is connected to the slider 420, and the bottom end of the elastic element 500 is connected to the hinge shaft 310. Then, the elastic force of the elastic element 500 pulls the slider 420 to slide downward along the slide groove 321, thereby causing the locking seat 400 to have a downward tendency to move.

[0061] Each locking seat 400 is also provided with a locking block 410 at its bottom. The guide groove 220 and the locking hole 210 are located on the rotation trajectory of the locking block 410 as the handrail 300 rotates upward. When the handrail 300 drives the locking seat 400 to rotate upward, the locking seat 400 rotates to the top of the hinge seat 200. The elastic force of the elastic element 500 pulls the slider 420 to slide downward along the slide groove 321, causing the locking seat 400 to slide downward, so that the locking block 410 is inserted into the locking hole 210 along the guide groove 220.

[0062] The guide groove 220 limits the rotation trajectory of the locking block 410, ensuring that the locking block 410 can be aligned with the locking hole 210 after rotating above the hinge seat 200, and ensuring that the elastic element 500 can pull the locking seat 400 downward so that the locking block 410 can be inserted into the locking hole 210 to complete the locking.

[0063] As the bedridden user rotates the armrest 300 to drive the locking seat 400 upwards, bringing the locking seat 400 above the hinge seat 200, the guide groove 220, which gradually tilts upwards from back to front, guides the locking block 410. This transforms the force of the bedridden user rotating the armrest 300 into the force of the guide groove 220 pushing the locking block 410 upwards. The locking block 410 is gradually pushed upwards until it falls into the locking hole 210, eliminating the need for the bedridden user to manually push the locking seat 400. This makes it more convenient for the bedridden user to flip the armrest 300 upwards.

[0064] The top surface of the locking hole 210 is also set in the same inclined state as the guide groove 220, which helps the locking block 410 to be smoothly inserted into the locking hole 210. When the armrest 300 needs to be folded down, after the bedridden user pushes the locking seat 400 upward, since the top surface of the locking hole 210 gradually tilts downward from front to back, the bedridden user does not need to keep pushing the locking seat 400 upward for a long time. He only needs to push the locking seat 400 upward at the moment of folding the armrest 300 so that the locking block 410 moves above the top surface of the locking hole 210. As the armrest 300 is folded backward and downward, the locking block 410 can slide along the inclined top surface of the locking hole 210, making the operation of folding the armrest 300 downward more convenient.

[0065] The locking block 410 is positioned in front of the handrail 300. Since the bedridden user is holding onto the handrail 300 in front, the handrail 300 is supported by the supporting force of the surrounding end face of the locking block 410 and the top surface of the hinge seat 200, thus preventing the handrail 300 from folding forward to the user's side.

[0066] The elastic element 500 is placed inside the hinge tube 320 to prevent the elastic element 500 from being exposed to the outside, thus preventing the stretching elastic element 500 from clamping the mattress or blankets of the nursing bed.

[0067] Reference Figures 1 to 5 As shown, the connecting rod 600 connects two locking seats 400, so that the bedridden user can use the connecting rod 600 to push the two locking seats 400 upward at the same time, so that the two locking blocks 410 disengage from the locking holes 210 on the top of the two hinge seats 200, making the folding of the armrest 300 more convenient.

[0068] The vertical support 120 of the support frame 100 is placed on the ground and the horizontal support 130 is placed under the mattress of the nursing bed to fix the support frame 100. The bedridden user folds the armrest 300 upward on the nursing bed. The bedridden user pushes the locking seat 400 upward against the elastic force of the elastic member 500. Then the armrest 300 drives the locking seat 400 to rotate above the hinge seat 200. After the locking seat 400 is released, the elastic force of the elastic member 500 causes the locking block 410 at the bottom of the locking seat 400 to insert into the locking hole 210 at the top of the hinge seat 200, so that the armrest 300 is fixed so that the bedridden user can use the armrest 300.

[0069] When the armrest 300 needs to be folded down, the bedridden user pushes the locking seat 400 upward against the elastic force of the elastic element 500, causing the locking block 410 to disengage upward from the locking hole 210. Then, the bedridden user folds the armrest 300 down to fold it to the side of the mattress.

[0070] Therefore, the folding operation of the armrest 300 is relatively convenient, and bedridden users can independently complete the folding action of the armrest 300.

[0071] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
