Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of hospital beds, in particular to a multi-position bed rail. Background Art
[0002] The one-way folding method adopted by traditional bed guardrails leaves a large space at the end of the bed after the bed rails are raised, and the height is also insufficient. After adding air cushions to many beds, the bed rails are not high enough. Some patients, especially those with dementia, often get out of bed without permission in the gap between the bed rails when the nurses are not paying attention, or patients lying on the air cushion bed are prone to fall from the bed rails when they turn over by themselves, which eventually causes adverse events such as falls and falling out of bed. Utility Model Content
[0003] The technical problem to be solved by the utility model is to provide a multi-position bed rail to solve one or more technical problems existing in the prior art and at least provide a beneficial choice or create conditions.
[0004] The solution of the utility model to solve the technical problem is:
[0005] A multi-position bed rail comprises: two horizontal rails arranged vertically and parallel to each other, the horizontal rails extending along a first direction;
[0006] At least two supporting structures, the supporting structures comprising a plurality of supporting members and a plurality of limiting assemblies, the supporting members and the limiting assemblies being arranged in one-to-one correspondence; the two horizontal bars being respectively arranged as a first horizontal bar and a second horizontal bar; the second horizontal bar being provided with a sliding space;
[0007] The plurality of support members are arranged along the first direction, and the plurality of support members are arranged in parallel, one end of the support member is hinged to the first cross bar, and the other end is hinged to a sliding member, the sliding member is slidingly connected to the second cross bar, and the sliding member is slidingly connected along the first direction in the sliding space; when one of the cross bars moves upward, the sliding member moves along the first sliding direction;
[0008] The limit assembly is arranged on the second cross bar, and the limit assembly includes an elastic reset member and a plurality of gear limit blocks arranged along the first direction, the gear limit block is slidably connected to the second cross bar, the gear limit block is used to limit the position of the sliding member in the first direction, the gear limit block is provided with a guide slope, and the guide slope deviates from the first sliding direction; the elastic reset member is used to drive the gear limit block to reset to the sliding space;
[0009] The first sliding directions of the two support structures are arranged in opposite directions.
[0010] Through the above technical solution, when one of the horizontal bars moves upward, the sliding member slides along the first sliding direction in the sliding space. During the sliding process of the sliding member along the first sliding direction in the sliding space, the sliding member will contact the guide inclined surface of the gear limit block, thereby causing the gear limit block to automatically move in the direction away from the sliding space.
[0011] When the gear limit block is driven to move in the direction away from the sliding space, the elastic reset part accumulates elastic potential energy. After the external force is cancelled, the elastic potential energy accumulated by the elastic reset part is released, and the gear limit block is driven to move in the direction close to the sliding space, so that the gear limit block re-enters the sliding space, and the end face of the gear limit block limits the sliding part to prevent the sliding part from sliding in the direction opposite to the first sliding direction, thereby avoiding the upper horizontal rail from descending, so that the multi-speed bed rail can play a protective role.
[0012] By setting the number of the gear limit blocks to be multiple, the bed rail can have multiple gears, so that the first horizontal rail can be fixed at multiple different heights to meet the height requirements of the bed rail.
[0013] As a further improvement of the above technical solution, it also includes:
[0014] A control button, wherein the control button is arranged on the second horizontal bar;
[0015] A gear linkage component, wherein the control button is connected to the gear limit block via the gear linkage component, and when the control button is pressed, the gear limit block is separated from the sliding space.
[0016] Through the above technical solution, the movement of the gear limit block is controlled by the control button, which can reduce the trouble of medical staff in finding the gear limit block.
[0017] As a further improvement of the above technical solution, the gear linkage assembly includes: a roller rotatably connected to the second horizontal bar, the roller and the gear limit block are arranged in a one-to-one correspondence;
[0018] A control line is arranged in one-to-one correspondence with the gear limit block, and the control line is fixed to the gear limit block after passing around the roller;
[0019] A first pulling block, wherein the first pulling block is slidably connected to the second horizontal bar, the first pulling block is provided with a first driving inclined surface, and the first driving inclined surface faces the roller; an end of the control line away from the gear limit block is fixed to the first pulling block;
[0020] A second pulling block, the second pulling block is fixedly connected to the control button, the second pulling block is provided with a second driving inclined surface, the second driving inclined surface abuts against the first driving inclined surface, when the control button is pressed, the first pulling block moves in a direction away from the roller, thereby driving the gear limit block to leave the sliding space.
[0021] Through the above technical solution, when the control button is pressed, the second pulling block moves in the second direction, and the second driving inclined plane cooperates with the first driving inclined plane to drive the first pulling block to move in the first direction. When the first pulling block moves in the first direction, the control line will pull the gear limit block to move in the direction away from the sliding space, so that the gear limit block is out of the sliding space, thereby canceling the limit of the sliding member, and the first horizontal bar will automatically slide down due to its own gravity, thereby avoiding the bed rails from hindering certain medical care procedures.
[0022] By controlling multiple gear limit blocks through a first pulling block, the work intensity of medical staff can be reduced and the work efficiency of medical staff can be improved.
[0023] As a further improvement of the above technical solution, the elastic return member is a spring.
[0024] As a further improvement of the above technical solution, the total number of the support members is not less than three.
[0025] As a further improvement of the above technical solution, the number of the supporting members in each supporting structure is three.
[0026] As a further improvement of the above technical solution, the number of the gear limit blocks in each limit assembly is not less than two.
[0027] As a further improvement of the above technical solution, the second horizontal bar is provided with a stroke limiter, and the stroke limiter is used to limit the maximum stroke of the sliding member.
[0028] The beneficial effect of the utility model is that the first horizontal rail can be fixed at a plurality of different heights to meet the height requirements of the bed rails.
[0029] The utility model is used in the technical field of hospital beds. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] The multi-position bed rail comprises: a horizontal rail, a support structure 200 , a control button 300 , and a gear linkage assembly 400 .
[0040] The number of the horizontal bars is set to two, the two horizontal bars are arranged parallel to each other, the two horizontal bars extend along the first direction, and the two horizontal bars are arranged along the up-down direction.
[0041] Specifically, the two horizontal bars are respectively set as the second horizontal bar 120 and the first horizontal bar 110. In the present embodiment, the first horizontal bar 110 is arranged above the second horizontal bar 120. In other embodiments, the second horizontal bar 120 can also be arranged above the first horizontal bar 110. Those skilled in the art can select the arrangement positions of the second horizontal bar 120 and the first horizontal bar 110 according to actual needs.
[0042] The second horizontal bar 120 is provided with a sliding space 121, and the sliding space 121 extends along the first direction. The number of the sliding spaces 121 is set to be multiple. In this embodiment, the multiple sliding spaces 121 are arranged in a rectangular shape. In other embodiments, the multiple sliding spaces 121 can also be arranged along the first direction. Those skilled in the art can select the arrangement of the multiple sliding spaces 121 according to actual needs.
[0043] Travel limiters 122 are respectively provided at two ends of the sliding space 121 in the length direction. The travel limiters 122 are used to limit the maximum travel of an object sliding in the sliding space 121 along the first direction.
[0044] The number of the support structures 200 is set to at least two. Specifically, in this embodiment, the number of the support structures 200 is set to two. In other embodiments, the number of the support structures 200 may also be set to three, four, etc. Those skilled in the art may select the specific number of the support structures 200 according to actual needs. The two support structures 200 are arranged along the second direction.
[0045] Specifically, the support structure 200 includes a limit assembly 210 and a support member 220 . The number of the limit assembly 210 and the support member 220 are both set to be multiple, and the limit assembly 210 and the support member 220 are set in a one-to-one correspondence.
[0046] Multiple support members 220 in the same support structure 200 are arranged along the first direction, and the multiple support members 220 are arranged parallel to each other. Specifically, in this embodiment, the number of support members 220 in the same support structure 200 is set to three. In other embodiments, the number of support members 220 in the same support structure 200 can also be set to four, five, etc. The number of support members 220 in the same support structure 200 can be selected by those skilled in the art according to actual needs. The upper end of the support member 220 is hingedly connected to the first horizontal bar 110 through a hinge shaft, and the lower end of the support member 220 is connected to the sliding member 221 through a hinge shaft. The sliding member 221 is arranged in the sliding space 121, and the sliding member 221 is slidingly connected to the second horizontal bar 120, so that the sliding member 221 can slide relative to the second horizontal bar 120 in the sliding space 121 along the first direction.
[0047] The limiting assembly 210 is disposed on the second horizontal bar 120 . Specifically, the limiting assembly 210 includes a gear limiting block 211 and an elastic return member 212 .
[0048] The gear limit block 211 is slidably connected to the second horizontal bar 120. Specifically, in this embodiment, the gear limit block 211 can slide along the third direction relative to the second horizontal bar 120. In other embodiments, the relative sliding direction of the gear limit block 211 and the second horizontal bar 120 can also be set to be parallel to the second direction. Those skilled in the art can specifically set the arrangement position and sliding direction of the gear limit block 211 according to actual needs. When the first horizontal bar 110 moves upward relative to the second horizontal bar 120, the inclination angle of the support member 220 changes, so that the sliding member 221 slides along the first sliding direction in the sliding space 121.
[0049] The first sliding directions of the two support structures 200 are arranged in opposite directions, so that the support members 220 of the two support structures 200 are arranged crosswise, thereby supporting the first crossbar.
[0050] The gear limiting block 211 is provided with a guiding inclined surface 2111 , and the guiding inclined surface 2111 is away from the first sliding direction.
[0051] Specifically, in this embodiment, the number of gear limit blocks 211 in the same limit assembly 210 is set to multiple, and the multiple gear limit blocks 211 are arranged along the first direction. Setting the number of gear limit blocks 211 to multiple can enable the bed rail to have multiple gears, so that the first horizontal rail 110 can be fixed at multiple different heights to meet the height requirements of the bed rail.
[0052] The elastic reset member 212 is disposed between the gear limit block 211 and the second horizontal bar 120, and the elastic reset member 212 is disposed one-to-one with the gear limit block 211. Specifically, in this embodiment, the elastic reset member 212 is configured as a spring, and in other embodiments, the elastic reset member 212 may also be configured as a leaf spring or other elastic member, and those skilled in the art may select the specific structure of the elastic reset member 212 according to actual needs.
[0053] When the first horizontal bar 110 moves upward relative to the second horizontal bar 120, the sliding member 221 slides along the first sliding direction in the sliding space 121. During the sliding process of the sliding member 221 along the first sliding direction in the sliding space 121, the sliding member 221 will contact the guiding inclined surface 2111 of the gear limit block 211, so that the gear limit block 211 automatically moves in the direction away from the sliding space 121.
[0054] When the gear limit block 211 is driven to move in a direction away from the sliding space 121, the elastic reset member 212 accumulates elastic potential energy. After the external force is removed, the elastic potential energy accumulated by the elastic reset member 212 is released, and the gear limit block 211 is driven to move in a direction close to the sliding space 121, so that the gear limit block 211 re-enters the sliding space 121, and the end face of the gear limit block 211 limits the sliding member 221 to prevent the sliding member 221 from sliding in a direction opposite to the first sliding direction, thereby preventing the first horizontal rail 110 from descending, so that the multi-speed bed rail can play a protective role.
[0055] The control button 300 is disposed on the second horizontal bar 120. The control button 300 is connected to the gear limit block 211 through the gear linkage assembly 400.
[0056] The gear linkage assembly 400 includes: a roller 410 , a control line 420 , a first pulling block 430 , and a second pulling block 440 .
[0057] The number of the first pulling block 430 and the second pulling block 440 is set to one, the first pulling block 430 is provided with a first driving inclined surface 431, and the second pulling block 440 is provided with a second driving inclined surface 441. The first driving inclined surface 431 faces the roller 410, and the second driving inclined surface 441 faces away from the roller 410. The second pulling block 440 is fixedly connected to the control button 300.
[0058] The roller 410 is arranged in a one-to-one correspondence with the gear limit block 211, the roller 410 is rotatably connected to the second horizontal bar, the control line 420 is arranged in a one-to-one correspondence with the gear limit block 211, the control line 420 bypasses the roller 410, one end of the control line 420 is fixedly connected to the gear limit block 211, and the other end of the control line 420 is fixedly connected to the first pulling block 430.
[0059] When the control button 300 is pressed, the second pulling block 440 moves in the second direction, and the second driving inclined surface 441 cooperates with the first driving inclined surface 431 to drive the first pulling block 430 to move in the first direction. When the first pulling block 430 moves in the first direction, the control line 420 will pull the gear limit block 211 to move away from the sliding space 121, so that the gear limit block 211 is separated from the sliding space 121, thereby canceling the limit of the sliding member 221, and the first horizontal rail 110 will automatically slide down due to its own gravity, thereby preventing the bed rails from obstructing certain medical care procedures.
[0060] By controlling a plurality of gear limit blocks 211 through a first pulling block 430 , the work intensity of medical staff can be reduced and the work efficiency of medical staff can be improved.
[0061] Because traditional bed guardrails adopt a one-way folding method, a large space is left at the end of the bed after the bed rails are raised, and the height is also insufficient. After adding air cushions to many beds, the bed rails are not high enough. Some patients, especially those with dementia, often get out of bed without permission in the gap between the bed rails when the nurses are not paying attention, or patients on air beds turn over by themselves and are prone to fall from the bed rails, eventually causing adverse events such as falls and falling out of bed.
[0062] The multi-level bed rail adopts a vertical rising and falling form, which can avoid leaving gaps, thereby effectively protecting the patient, and is provided with a multi-level adjustment form, so that the first horizontal rail 110 can stay at different heights to adapt to the bed with an air cushion.
[0063] The preferred implementation modes of the present invention are specifically described above, but the present invention is not limited to the described embodiments. Those skilled in the art may make various equivalent modifications or substitutions without violating the spirit of the present invention, and these equivalent modifications or substitutions are all included in the scope defined by the claims of this application.
