[0001] This utility model relates to the field of nursing equipment technology, specifically a folding and locking bedside handrail. Background Technology

[0002] As society develops, the proportion of the elderly population is gradually increasing. As people age, their physical functions decline, making it difficult to move from a lying to a sitting position, and vice versa, often requiring hand support. To address this, handrails are typically installed around the bed. Additionally, people with disabilities, illnesses, and young children also need assistance with using their hands when lying down and getting out of bed.

[0003] Existing technology, such as Chinese invention patent document, publication number CN117503515A, discloses a foldable bedside guardrail, which discloses a buckling device and a guardrail body. The guardrail body is a walking aid, but the buckling device has a relatively complex structure, making it difficult for users with mobility impairments to lock or unlock the guardrail body, which is not conducive to their use. At the same time, only the supporting handrail of the guardrail body can be folded, while the entire guardrail body cannot be folded for storage, resulting in it taking up a large area and easily causing others to trip.

By releasing the locking between the fixing member 62 and the locking member 63, the user can allow the bottom rod 7 to rotate on the connector 60, thereby allowing the guardrail body to be folded and stored.

[0031] In this embodiment, the cross bracket 1 is composed of two support rods connected in a cross manner. The telescopic rod 2 has a rotating part at the middle position on the side near the cross bracket 1. The two sides of the cross bracket 1 are rotatably connected to the telescopic rod 2 through the rotating part and the connecting part 60. The telescopic rod 2 is composed of a sleeve, a movable rod and a spring telescopic sheath. The rotating part is connected to the movable rod. The user can retract the cross bracket 1 by cooperating between the rotating part and the connecting part 60 on the movable rod, so that the guardrail body can be further folded and stored.

[0032] In this embodiment, a sliding groove is provided on the bottom side of the mounting plate 50 away from the fixed locking member 52. Mounting grooves are provided on both sides of the interior of the mounting plate 50 and are connected to the sliding groove. The mounting plate 50 is slidably connected to the movable locking member 54 through the sliding groove. Movable openings are provided on both sides of one end of the mounting plate 50. A pull rod is provided on the side of the push rod 53 away from the fixed locking member 52. The mounting plate 50 is slidably connected to the pull rod through the movable opening. The user can push the push rod 53 to move in the mounting groove through the pull rod, which will cause the movable locking member 54 to move along the sliding groove, so that it can move away from the fixed locking member 52, thereby releasing the lock between the fixed locking member 52 and the movable locking member 54, and thus the connecting rod 4 can be removed from between the fixed locking member 52 and the movable locking member 54.

[0033] In this embodiment, a groove is provided in the middle of one side of both the fixed locking member 52 and the movable locking member 54. The size of the groove on the fixed locking member 52 and the movable locking member 54 is adapted to the size of the connecting rod 4. The connecting rod 4 is sleeved with the fixed locking member 52 and the movable locking member 54 through the groove, so that the connecting rod 4 can be stably fixed between the fixed locking member 52 and the movable locking member 54.

[0034] In this embodiment, the bottom of the grooves on the fixed locking member 52 and the movable locking member 54 are provided with protrusions, and a slot is provided at the middle position of the bottom of the connecting rod 4.

[0035] Working principle: The guardrail body is composed of cross bracket 1, telescopic rod 2, handle 3, connecting rod 4, connecting structure 6, base rod 7, front wheel hub 8, and rear wheel hub 9. The user can release the lock between the fixing part 62 and the latch 63 by rotating the rotating disc 61. The base rod 7 can then rotate via the connecting part 60, allowing the guardrail body to fold, thus reducing its footprint. If a user with mobility issues needs to get out of bed, the user can push the push rod 53 to move the movable locking part 54, thereby releasing the lock between the connecting rod 4 and the fixed locking part 52 and the movable locking part 54. After the user removes the guardrail body from the locking structure 5, the elastic force of the elastic element 55 drives the movable locking element 54 to reset. After the user gets into bed, the user lifts the guardrail body, causing the connecting rod 4 to move by squeezing the movable locking element 54 through the guide grooves on the fixed locking element 52 and the movable locking element 54. After the connecting rod 4 enters the groove, the elastic element 55 resets, allowing the fixed locking element 52 and the movable locking element 54 to lock the connecting rod 4, thereby installing the guardrail body on the locking structure 5. The guardrail body then functions as a bedside handrail.
