Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medical equipment, in particular to a bed rail and a hospital bed. Background Art
[0002] Bedrails are crucial for protecting bedridden patients, and their design directly impacts their effectiveness in preventing falls and out-of-bed injuries. Traditional bedrails often utilize a one-way folding design. This creates a significant gap at the foot of the bed when the rails are raised. Furthermore, the rails themselves may not be high enough to accommodate all situations (especially when the bed is equipped with an air cushion), significantly reducing their effectiveness.
[0003] Elderly patients, especially those with Alzheimer's disease, may exploit this gap in the bed when their caregivers are not paying attention, increasing the risk of falls. For patients using airbeds, the extra height of the mattress makes traditional bed rails inadequate to prevent them from accidentally sliding out of bed when turning or moving, potentially leading to falls and other accidents, seriously threatening their safety and health. Utility Model Content
[0004] The purpose of the present utility model is to provide a bed rail and a hospital bed to solve one or more technical problems existing in the prior art and at least provide a beneficial choice or create conditions.
[0005] The technical solutions adopted to solve the above technical problems are:
[0006] The cam is adapted to move the locking member so that the cam is in a position to move relative to the locking member when the cam is in a position to move relative to the locking member when the cam is in a position to move relative to the locking member when the cam is in a position to move relative to the locking member when the cam is in a position to move relative to the locking member when the cam is in a position to move relative to the locking member
[0007] The beneficial effects of the utility model are:
[0008] During use, the pressing block is pressed, the movable block moves upward, and the locking block moves laterally out of the engaging groove, releasing the lock between the vertical rod and the mounting groove. The lifting bar assembly can now be adjusted to a suitable height as needed. When the desired height is reached, the pressing block is released, and the pressing block moves upward under the action of the elastic member, simultaneously driving the movable block downward, which in turn drives the locking block laterally to engage and lock with the engaging groove. This utility model can raise or lower the lifting bar assembly to any height and completely blocks the edge of the bed, leaving no large space at the foot of the bed. It is safer to use and its modular design facilitates installation on existing beds.
[0009] As a further improvement to the above technical solution, the first gear is rotatably mounted on the horizontal rod, and the second gear is rotatably mounted on the lower end of the vertical rod. The first gear meshes with the racks of the movable block and the pressing block, respectively, and the second gear meshes with the racks of the movable block and the locking block, respectively. The first gear causes the movable block and the pressing block to move in opposite directions, while the second gear causes the movable block to drive the locking block to move laterally, thereby changing the direction of movement of the locking block.
[0010] As a further improvement to the above technical solution, the movable block, locking block, first gear, and second gear are each provided in pairs, with the two first gears symmetrically located on either side of the pressing block. The pressing block can simultaneously control the locking and releasing of the two locking blocks, thereby increasing the strength of the engagement without increasing operational complexity.
[0011] As a further improvement of the above technical solution, the cross bar is a hollow structure, and a pressing hole is provided on the upper side of the cross bar for the pressing block to extend out. The elastic member and the first gear are arranged inside the cross bar, and the locking structure is arranged inside the cross bar to protect the locking structure.
[0012] As a further improvement to the above technical solution, the vertical rod is hollow, and the movable block, locking block, and second gear are all disposed inside the vertical rod. The locking block extends from the interior of the vertical rod and engages with the engaging groove. The locking structure is disposed inside the vertical rod to protect the locking structure.
[0013] As a further improvement to the above technical solution, a limit block is provided on the inner side wall of the installation slot, and a sliding block is provided at the lower end of the vertical rod to abut against the limit block. When the vertical rod is raised, the limit block abuts against the sliding block to prevent the vertical rod from falling out of the installation slot.
[0014] As a further improvement of the above technical solution, the sliding block is slidably arranged in the installation groove to improve the sliding stability, and the vertical rod will not shake when the vertical rod is raised or lowered.
[0015] As a further improvement of the above technical solution, the cross section of the mounting groove is circular, and the sliding block is a cylindrical block.
[0016] As a further improvement of the above technical solution, the pressing block is arranged in the middle position of the bed rail, and the clamping structure is located in the middle position, so that the structure is more stable.
[0017] The present invention also provides a hospital bed comprising any of the above-described bed rails. The bed rails can be raised or lowered to any height and completely block the edge of the bed, eliminating any large gap at the foot of the bed. This makes the bed safer to use, and is particularly useful for beds equipped with air cushions, as the bed rails can be raised to a higher height as needed. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] Reference Figures 1 to 2 The present invention provides a bed rail and a hospital bed in the following embodiments:
[0026] In some embodiments, a bed rail comprises a mounting shell 100, a lifting rail assembly 200, and a locking assembly. In this embodiment, the bed rail is mounted on the front edge of a hospital bed.
[0027] The mounting shell 100 is extended left and right, and a plurality of mounting slots 110 are provided at intervals from left to right on the mounting shell 100, and the openings of the mounting slots 110 face upwards;
[0028] The lifting bar assembly 200 includes a cross bar 210 and a plurality of vertical bars 220. The lower ends of the vertical bars 220 are slidably inserted into the mounting grooves 110. The upper ends of the plurality of vertical bars 220 are connected to the cross bar 210. By holding the cross bar 210, the bed rail can be raised and lowered. The cross bar 210 and the vertical bars 220 are both hollow structures. The locking assembly can be installed in the hollow structure to protect the locking structure. The structure is also more compact and the appearance is more beautiful.
[0029] The locking assembly includes a pressing block 310, an elastic member 320, a movable block 330, a locking block 340, a first gear 350 and a second gear 360. The locking block 340 is extended left and right. The locking block 340 is laterally movable at the lower end of the vertical rod 220. The inner side wall of the mounting groove 110 is provided with a plurality of snap-fit grooves 111 spaced apart up and down. The snap-fit grooves 111 are snap-fitted to the locking block 340 to lock the vertical rod 220.
[0030] A pressing hole is provided on the upper side of the middle position of the cross bar 210, and a pressing block 310 can be extended from the pressing hole. The pressing block 310 is arranged inside the cross bar 210 for moving up and down. An elastic member 320 is provided between the bottom of the pressing block 310 and the cross bar 210. Under the action of the elastic force of the elastic member 320, the pressing block 310 is reset upward.
[0031] The elastic member 320 can be an elastic sheet or a spring, and a spring is used in this embodiment. A first transmission gear is provided on both the left and right sides of the pressing block 310, and the first transmission gear is meshed with the active sides of the pressing block 310. A movable block 330 is provided next to the first transmission gear. The movable block 330 is provided with a rack on the surface close to the first gear 350, and the rack is also meshed with the first gear 350. A connecting hole is provided on the lower side of the crossbar 210. The movable block 330 extends from the inside of the crossbar 210 to the inside of the vertical bar 220, extending all the way to the lower end of the vertical bar 220 and close to the locking block 340. The locking block 340 and the movable block 330 are both provided with a rack meshed with a second gear 360, and the second gear 360 is rotatably arranged inside the vertical bar 220.
[0032] During use, the pressing block 310 is pressed downward, causing the first gear 350 to rotate, driving the movable block 330 upward. Simultaneously, the second gear 360 rotates, which in turn drives the locking block 340 to move laterally out of the engaging slot 111, releasing the lock between the vertical rod 220 and the mounting slot 110. The lifting rail assembly 200 can now be adjusted to a desired height. When the desired height is reached, the pressing block 310 is released. The pressing block 310, under the action of the elastic member 320, moves upward, simultaneously driving the movable block 330 downward, which in turn drives the locking block 340 to move laterally and engage and lock with the engaging slot 111. This bedrail can completely block the edge of the bed. To get in and out of bed, the pressing block 310 can be installed, lowered to a level position with the bed surface, and then exited. This eliminates the need for leaving space at the foot or head of the bed for entry and exit, as is required with traditional bedrails. Furthermore, when the bed requires an elevated air mattress, the bedrail can be raised to maintain adequate protection.
[0033] In this embodiment, there are two movable blocks 330, two locking blocks 340, two first gears 350, and two second gears 360, and the two first gears 350 are symmetrically arranged on either side of the pressing block 310. The pressing block 310 can simultaneously control the locking and releasing of the two locking blocks 340, thereby improving the clamping strength without increasing the complexity of the operation.
[0034] In some other embodiments, the movable block 330 , the locking block 340 , the first gear 350 and the second gear 360 may be set to one, for example, on the left or right side of the pressing block 310 .
[0035] As a further improvement, a limit block 112 is provided at the upper end of the inner side wall of the mounting groove 110, and a sliding block 221 is provided at the lower end of the vertical rod 220, which abuts against the limit block 112. When the vertical rod 220 is lifted upward, the sliding block 221 contacts and abuts against the limit block 112.
[0036] This effectively prevents the vertical rod 220 from being dislodged from the mounting slot 110 due to excessive force in lifting the horizontal rod 210 upward. Therefore, this improvement enhances the overall stability of the bed rail system and provides users with a more secure and reliable use guarantee.
[0037] As a further improvement, the sliding block 221 is slidably arranged in the mounting groove 110 to improve the sliding stability. When the vertical rod 220 is raised or lowered, the vertical rod 220 will not shake, effectively avoiding the jamming or blocking phenomenon that may occur in the traditional design, and showing anti-shaking performance when the vertical rod 220 is raised or lowered.
[0038] In this embodiment, the cross section of the mounting groove 110 is circular, and the sliding block 221 is a cylindrical block. In other embodiments, the cross section of the mounting groove 110 is rectangular, and the sliding block 221 is a columnar block.
[0039] In this embodiment, the pressure block 310 is positioned in the center of the bedrail. This layout not only reflects the aesthetic symmetry of the design but also enhances structural stability. By positioning the snap-in structure in the center, the stress points are effectively dispersed, resulting in greater stability and durability under pressure. This design strategy not only optimizes the bedrail's load-bearing capacity but also ensures safety and reliability during long-term use, providing users with a more stable and secure user experience.
[0040] In other embodiments, the horizontal rod 210 and the plurality of vertical rods 220 may also be solid structures, and the locking members need to be installed on the outer sides of the rod and the plurality of vertical rods 220 .
[0041] This new bedrail provides comprehensive protection for the bed's edges, overcoming the limitations of traditional bedrails. Its unique feature is that, through a lifting mechanism, it can be easily adjusted to seamlessly connect with the bed surface or to any safe height. This ensures that when the patient enters or exits the bed, the bedrail can be lowered to be flush with the bed surface, eliminating the need for a traditional gap for entering or exiting the bed, and thus eliminating potential safety hazards at the foot or head of the bed.
[0042] This design not only improves bed safety but also significantly enhances patient comfort and convenience. Users can flexibly adjust the bedrail height to suit their individual needs or medical requirements, achieving comprehensive safety protection. Furthermore, the modular design concept makes the bedrail system easy to install on a variety of existing beds, allowing for rapid upgrades to bed safety without requiring complex structural modifications, demonstrating exceptional adaptability and convenience.
[0043] In summary, the bed rail system of the present invention provides patients with a safer and more comfortable hospitalization environment with its comprehensive protection capabilities, flexible lifting and adjustment, and convenient modular installation.
[0044] The present invention further provides an embodiment of a hospital bed, including any of the bedrails described above. If the bed is against a wall, the bedrail is installed on the side of the bed that is not against the wall. If the bed is not against a wall, the bedrail is installed on both sides of the bed. The bedrail can be raised or lowered to any height and completely blocks the edge of the bed, eliminating any large gap at the foot of the bed, making it safer to use. In particular, for beds equipped with air cushions, the bedrail can be raised to a higher height as needed.
[0045] The above specifically describes the preferred embodiments of the present invention, but the invention is not limited to the embodiments. Those skilled in the art can make various equivalent modifications or substitutions without violating the spirit of the present invention. These equivalent modifications or substitutions are all included in the scope defined by the claims of this application.
