Description

Technical Field

[0001] This utility model relates to the field of companion bed technology, specifically to a retractable shared companion bed. Background Technology

[0002] Companion beds are specialized furniture designed for medical institutions (such as hospitals, rehabilitation centers, and nursing homes) to provide temporary rest for patients' family members or caregivers, while also ensuring convenient care. Fixed-form companion beds continuously occupy valuable space regardless of use, leading to narrow ward passageways and cluttered layouts. This not only hinders medical staff from quickly responding to treatment needs (such as moving equipment during emergency resuscitation) but also affects the convenience of patients getting in and out of bed and the daily caregiving activities of family members. Therefore, retractable companion beds can flexibly switch between states according to actual needs. They can be quickly unfolded when rest is needed to meet temporary rest requirements and promptly folded away when not in use, avoiding unnecessary space occupation. Currently, the operation of retractable companion beds... The operation relies on specific mechanisms, such as latch unlocking, hydraulic rod drive, and spring return, to achieve form switching. The physical premise for the folding and unfolding action is that a certain gap must be reserved between adjacent bed boards, bed frames, and other moving parts to avoid friction and jamming when the parts rotate, ensuring smooth folding and unfolding. However, during the operation of folding the companion bed, the user needs to hold the edge of the bed board and apply force to drive the bed board to rotate. During the rotation of the bed board, a force is generated that causes the gap to close quickly, and this closing action is accompanied by a significant impact. During this process, the user's hand needs to be close to the edge of the bed board to exert force, and it is easy for the hand to slip into the gap area under the impact force, which can lead to the risk of being pinched and seriously affect the safety of using the companion bed. Utility Model Content

[0003] The purpose of this invention is to provide a retractable shared companion bed to address the aforementioned shortcomings in the technology.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a retractable shared companion bed, comprising a bed frame and a long board, wherein two sets of safety retraction components for preventing hand pinching are provided between the bed frame and the long board; Each set of safety retraction components includes a connecting seat fixedly connected to the bottom of the bed frame and the long board. Each of the two connecting seats has a movable groove on one side. A connecting shaft is movably connected inside each of the two movable grooves. A distance torsion bracket is installed between the two connecting shafts. The bed frame forms and maintains a preset safety retraction distance with the long board through the distance torsion bracket. A flexible plate is installed on the side of the bed frame near the connecting seat. One side of the bed frame is equipped with a buffer assembly that drives the flexible plate for fine adjustment; A shallow-deep component is provided between the bed frame and the buffer assembly, and the shallow-deep component is used to drive the flexible board to make horizontal adjustment along one side of the bed frame.

[0005] Preferably, the buffer assembly includes a connecting frame fixedly connected to the bed board frame near the connecting seat and a mounting frame installed on one side of the connecting frame. The mounting frame is used to drive the flexible plate to adjust. The mounting frame has a displacement groove on the side near the flexible plate for guiding the movement of the flexible plate. A return spring is connected between the displacement groove and the flexible plate.

[0006] Preferably, two symmetrical guide posts are fixedly connected to one side of the flexible plate, and two guide grooves are provided on one side of the mounting frame for the two guide posts to be inserted, and the flexible plate moves stably along the displacement groove through the guide posts.

[0007] Preferably, the shallow-deep component includes a semi-circular groove formed on one side of the connecting frame and a displacement column fixedly connected to one side of the mounting frame, wherein the displacement column is embedded in the interior of the semi-circular groove, the opening of the semi-circular groove is provided as an arc-shaped structure, and the length of the connecting frame is greater than that of the mounting frame. One side of the connecting frame is provided with a stabilizing component that locks the displacement column in the semi-circular groove.

[0008] Preferably, the stabilizing component includes a fixing ring fixedly connected to one end of the connecting frame, and the fixing ring is sleeved on the outside of the displacement column. A connecting ring frame is fixedly connected inside the fixing ring. A plurality of silicone abutments are movably connected to one end of the connecting ring frame, and the plurality of silicone abutments are arranged in a circular array at one end of the connecting ring frame.

[0009] Preferably, one end of the fixing ring is screwed with a threaded sleeve, and part of the threaded sleeve is located inside the fixing ring. One end of the threaded sleeve is provided with a pressing groove, and the pressing groove is used to make several silicone abutments move closer to the outside of the displacement column. The pressing groove and the several silicone abutments maintain a slope fit.

[0010] The technical effects and advantages provided by this utility model in the above technical solution are as follows: This utility model, through the setting of the distance torsion frame and the flexible plate, enables the flexible plate to make stable contact with the user's hand, which is used to physically isolate and buffer the force on the hand between the bed frame and the long board. The movement of the flexible plate is used to buffer the impact force between the bed frame and the long board, prevent serious pinching injuries caused by hard squeezing, and improve the safety of the bed frame and the long board during the opening and closing process. This utility model utilizes the coordinated operation of displacement grooves and flexible plates. The flexible plate acts as an elastic medium, first contacting the long plate during retraction and extension. It absorbs the impact force through deformation, reducing the noise during retraction and extension. At the same time, the elastic contact can disperse the force points when the bed board rotates, avoiding component wear caused by hard contact and extending the service life of the companion bed. This invention allows for precise adjustment of the gap depth between the flexible board and the long board, enabling accurate control of the flexible board's coverage area based on changes in the gap between the bed frame and the long board. Furthermore, the engagement and disengagement of the threaded sleeve ensures a smooth adjustment process, preventing over- or under-adjustment that could lead to protective failure and further enhancing the safety of the companion bed.

[0015] This utility model provides, for example Figure 1 , Figure 2 , Figure 3 and Figure 4 The retractable shared companion bed shown includes a bed frame 1 and a long board 11, with two sets of safety retractable components 2 for preventing hand pinching between the bed frame 1 and the long board 11; Each set of safety retraction components 2 includes a connecting seat 21 fixedly connected to the bottom of the bed frame 1 and the long plate 11. Each of the two connecting seats 21 has a movable groove 22 on its corresponding side. The interior of each of the two movable grooves 22 is movably connected to a connecting shaft 23, and a distance torsion bracket 24 is installed between the two connecting shafts 23. The bed frame 1 forms and maintains a preset safety retraction distance with the long plate 11 through the distance torsion bracket 24. A flexible plate 25 is installed on the side of the bed frame 1 near the connecting seat 21. The specific structure and principle of the bed frame 1 and the long plate 11 are existing technologies, so they are not described in detail in this application.

[0016] refer to Figure 2 and Figure 4 As shown, a buffer assembly 3 is provided on one side of the bed frame 1 to drive the flexible plate 25 to make fine adjustments; the buffer assembly 3 includes a connecting frame 32 fixedly connected to the side of the bed frame 1 near the connecting seat 21 and a mounting frame 31 installed on one side of the connecting frame 32, and the mounting frame 31 is used to drive the flexible plate 25 to adjust. A displacement groove 33 is provided on the side of the mounting frame 31 near the flexible plate 25 to guide the movement of the flexible plate 25. A return spring 34 is connected between the displacement groove 33 and the flexible plate 25. Two symmetrical guide posts 35 are fixedly connected to one side of the flexible plate 25. Two guide grooves 36 are provided on one side of the mounting bracket 31 for the two guide posts 35 to be inserted. The flexible plate 25 moves stably along the displacement groove 33 through the guide posts 35.

[0017] refer to Figure 4 and Figure 5 As shown, a shallow-deep component 4 is provided between the bed frame 1 and the buffer assembly 3, and the shallow-deep component 4 is used to drive the flexible plate 25 to make horizontal adjustment along one side of the bed frame 1; the shallow-deep component 4 includes a semi-arc groove 42 opened on one side of the connecting frame 32 and a displacement column 41 fixedly connected to one side of the mounting frame 31, and the displacement column 41 is embedded in the interior of the semi-arc groove 42. The opening of the semi-arc groove 42 is set as an arc structure, and the length of the connecting frame 32 is greater than that of the mounting frame 31. A stabilizing component is provided on one side of the connecting frame 32 to lock the displacement column 41 in the semi-arc groove 42; the stabilizing component includes a fixing ring 43 fixedly connected to one end of the connecting frame 32, and the fixing ring 43 is sleeved on the outside of the displacement column 41. A connecting ring frame 44 is fixedly connected inside the fixing ring 43. A plurality of silicone abutments 45 are movably connected to one end of the connecting ring frame 44, and the plurality of silicone abutments 45 are arranged in a circular array at one end of the connecting ring frame 44. refer to Figure 4 and Figure 5As shown, a threaded sleeve 46 is screwed to one end of the fixing ring 43, and part of the threaded sleeve 46 is located inside the fixing ring 43. One end of the threaded sleeve 46 is provided with a pressing groove 47, which is used to bring several silicone abutments 45 closer to the outside of the displacement column 41. The pressing groove 47 and the several silicone abutments 45 maintain a slope fit. The part of the fixing ring 43 that is close to the threaded sleeve 46 is provided with an internal thread. Then, the internal thread of the fixing ring 43 and the external thread of the threaded sleeve 46 are screwed together, so that the fixing ring 43 and the threaded sleeve 46 maintain a screw connection restriction. Moreover, there are four flexible plates 25, and the part of the displacement column 41 that contacts the several silicone abutments 45 is set with a concave-convex structure to ensure that the silicone abutments 45 and the displacement column 41 maintain stable contact.

[0018] Working principle: When using: refer to Figure 4 and Figure 5 As shown, when the displacement column 41 needs to be adjusted to move along the interior of the semi-arc groove 42 to adjust the position of the flexible plate 25 at the port between the bed frame 1 and the long plate 11, the threaded sleeve 46 is rotated so that its external thread and the internal thread of the fixed ring 43 form a screw-drive engagement, driving the threaded sleeve 46 to move smoothly along the axial direction of the fixed ring 43. During the movement of the threaded sleeve 46, the extrusion groove 47 is simultaneously driven to move in the same direction. When the extrusion groove 47 moves, it realizes the linkage of rotation and horizontal displacement along the outer periphery of the four silicone abutments 45. As the relative displacement of the extrusion groove 47 and the silicone abutments 45 increases, the contact pressure between them gradually weakens. The four silicone abutments 45 move back to their original position along one end of the connecting ring frame 44 by means of their own elastic potential energy, and then slowly detach from the outer periphery of the displacement column 41 during the resetting process. refer to Figure 4 and Figure 5 As shown, the displacement column 41 is then released from its locked state inside the semi-arc groove 42 and the fixing ring 43. At this time, pushing the mounting bracket 31 can drive the displacement column 41 to move smoothly and horizontally along the inside of the semi-arc groove 42, thereby driving the flexible plate 25 to move horizontally synchronously along one side of the bed frame 1. With the long plate 11 and the bed frame 1 in a horizontally aligned state, the flexible plate 25 completes position adjustment within the gap between the two, realizing the adjustable depth of its position within the gap. Through this adjustment mechanism, the extension length of the flexible plate 25 can be precisely controlled according to actual usage needs, structurally preventing the user's hand from entering the gap between the bed frame 1 and the long plate 11, thereby effectively avoiding the risk of hand pinching. refer to Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, when the bed frame 1 and the long board 11 need to be retracted, the long board 11 is pushed to make it rotate along the bed frame 1 in an arc. During the movement of the long board 11, the connecting shaft 23 fixed to it is driven to rotate and cooperate with the inside of the distance torsion frame 24 along the movable groove 22. At this time, the connecting shaft 23 drives the long board 11 to complete the circular motion around the distance torsion frame 24, so that the gap between the long board 11 and the bed frame 1 changes dynamically with the rotation action. During this process, the flexible plate 25 always forms a protective barrier for the gap between the two, blocking the passage for the user's hand to enter the gap through physical blocking, thus avoiding the risk of pinching the hand from the source. refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, if the flexible plate 25 comes into contact with the user's hand, it will be driven to move along the inside of the displacement groove 33. At the same time, it will drive the two guide posts 35 to move smoothly along the axis of the return spring 34, ensuring the stability of the displacement process of the flexible plate 25. When the flexible plate 25 moves, it will simultaneously squeeze the return spring 34, causing it to elastically contract along the inside of the displacement groove 33. The elastic restoring force of the return spring 34 will give the flexible plate 25 a continuous reverse thrust, so that the flexible plate 25 and the user's hand remain in flexible contact. This achieves both physical isolation between the hand and the gap and buffers the impact force when the bed frame 1 and the long plate 11 close through spring deformation, avoiding serious pinching injuries caused by hard squeezing. In addition, when the long plate 11 is adjusted to be in a horizontal state with the bed frame 1, the flexible plate 25 forms a tight contact with one side of the long plate 11. The flexible contact replaces the direct collision between the long plate 11 and the hard edge of the bed frame 1, effectively suppressing the generation of harsh collision noise.

Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
