Description

Technical Field

[0001] This utility model relates to a bed-starting aid, and more particularly to a foldable bed-starting aid. Background Technology

[0002] A bed-starting aid is a daily care assistive device, mainly used by people with limited mobility to help them get out of bed. It is installed on the side of the bed, making it easier for people with limited mobility to use their strength to get up and down from the bed.

[0003] Currently, most bed starters on the market only offer basic support for getting out of bed and lack multi-functional designs tailored to individual user needs, making it difficult to meet the diverse usage scenarios and requirements of different users. For example, the armrests of existing bed starters are fixed. After the starter is installed on the side of the bed, the armrests can obstruct the side of the bed. When it is necessary to lift the legs and turn to get in and out of bed, the armrests can sometimes become obstacles, affecting the space for normal getting in and out of bed and causing inconvenience. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a bed-getting aid that is convenient for getting in and out of bed, has foldable armrests, and is easy to use, so as to meet different usage needs and solve at least one defect and deficiency in the prior art.

[0005] The technical solution adopted by this utility model is as follows: This utility model includes two vertically placed upright rod assemblies, a horizontally arranged transverse overlapping rod assembly, and a foldable armrest assembly. The two upright rod assemblies are symmetrical to each other. The transverse overlapping rod assembly is U-shaped, and its two ends are respectively connected and fixed to the two upright rod assemblies. The plane of the transverse overlapping rod assembly is perpendicular to the two upright rod assemblies and is used to insert between the mattress and the bed board to connect and fix it to the bed frame. The armrest assembly is connected to the top of the two upright rod assemblies and can be flipped and folded outwards to fold and abut against the outer side of the two upright rod assemblies when needed.

[0006] The top of the column rod assembly is provided with an upper end tube, and the bottom of the handrail assembly is provided with two lower end tubes. The two lower end tubes are respectively adapted to the positions of the two upper end tubes. The upper end tubes are fixedly connected with fasteners, and the lower end tubes are fixedly connected with rotating parts. The rotating parts and the fasteners are rotatably connected by a folding shaft so that the top ends of the handrail assembly and the two column rod assemblies can be flipped and folded.

[0007] The handrail assembly is equipped with a horizontal handle. Two rotating members have first elongated holes on their opposite inner sides. The two ends of the horizontal handle are inserted into these holes for positioning. The locking mechanism includes a backing and limiting portion, locking and fixing grooves on both sides, and a guide ramp in front of the locking and fixing grooves. When the handrail assembly is in an upright position, the back of the rotating member abuts against the backing and limiting portion, and both ends of the horizontal handle are simultaneously located at the bottom of the first elongated holes and the locking and fixing grooves, thus fixing the handrail assembly and the two column assemblies in the same vertical plane. For folding, the horizontal handle is lifted upwards. At this point, both ends of the handle horizontal pull rod are located at the top of the first elongated hole and are completely disengaged from the locking and fixing groove. Then, it flips outward, and after the handrail assembly rotates 180° around the folding axis, it comes into contact with the outer sides of the two column rod assemblies, completing the folding. When returning to the upright fixed state from the folded state, simply lift the handrail assembly. At this time, both ends of the handle horizontal pull rod slide along the guide slope. When the handrail assembly rotates nearly 180° in the opposite direction around the folding axis, both ends of the handle horizontal pull rod reach the highest point of the guide slope and then slide down into the bottom of the locking and fixing groove. At the same time, the back of the rotating part abuts against the contact limiting part, completing the reset.

[0008] The upper part of the lower tube is provided with a transverse pin, and the inner cavity of the lower tube is provided with a compression spring. One end of the compression spring abuts against the transverse pin, and the other end is provided with a washer located in the inner cavity of the lower tube. The two lower tubes are respectively provided with a second elongated hole on their opposite inner sides. The second elongated hole is adapted to the first elongated hole. The two ends of the handle are respectively inserted into the first elongated hole and the second elongated hole in sequence, and press against the washer, so that the compression spring is compressed between the transverse pin and the washer. At the same time, the rebound force of the compression spring presses the two ends of the handle against the bottom of the first elongated hole through the washer. Only when subjected to an upward lifting force, the two ends of the handle move upward in the first elongated hole, further pressing against the washer, thereby further compressing the compression spring. Once the lifting force disappears, the two ends of the handle return to the bottom position in the first elongated hole.

[0009] The height of the two column rod assemblies is adjustable to accommodate different bed heights.

[0010] The width of the handrail assembly is adjustable to suit different usage needs.

[0011] The handrail assembly is equipped with a rotating rod assembly, and the rotating rod assembly is equipped with an LED lighting module. The rotating rod assembly can rotate 360°, so that the LED lighting module can rotate 360° to adjust the lighting angle and direction.

[0012] The horizontal lap joint assembly is fixedly connected to the two column assemblies.

[0013] Alternatively, the transverse overlapping rod assembly and the two column rod assemblies can be connected by a quick-release mechanism to facilitate adjustment of the connection height between the transverse overlapping rod assembly and the column rod assembly.

[0014] The bottom of each of the two column rod assemblies is connected to a movable support foot. The movable support foot is connected to the two column rod assemblies by a ball joint-seat connection, allowing for rotation within its range of motion. Furthermore, the relative height between the movable support foot and the two column rod assemblies is adjustable.

[0015] The beneficial effects of this utility model are as follows: This utility model includes two vertically placed upright rod assemblies, a horizontally arranged transverse overlapping rod assembly, and a foldable armrest assembly. The two upright rod assemblies are symmetrical to each other. The transverse overlapping rod assembly is U-shaped, and its two ends are respectively connected and fixed to the two upright rod assemblies. The plane of the transverse overlapping rod assembly is perpendicular to the two upright rod assemblies and is used to insert between the mattress and the bed board for connection and fixation to the bed frame. The armrest assembly is connected to the top ends of the two upright rod assemblies and can be folded outwards to fold and align with the outer sides of the two upright rod assemblies when needed. This utility model overcomes the defects and shortcomings of the prior art. The handrail assembly is connected to the top of the two upright rod assemblies and can be folded outwards. When needed, it can be folded and aligned with the outer sides of the two upright rod assemblies. This changes the existing fixed handrail design of existing bed-getting aids. After the bed-getting aid is installed on the side of the bed, it avoids the obstruction caused by the handrail blocking the side of the bed when needing to lift legs and turn to get in and out of bed. After the handrail assembly is folded, the side of the bed is basically the same as when the bed-getting aid is not installed, which will not affect the space for normal getting in and out of bed, making it more convenient to use and improving comfort. Therefore, this utility model is a convenient bed-getting aid with foldable handrails that can meet different usage needs. Attached Figure Description

[0030] like Figures 1-10 As shown, the foldable bed-raising aid of this embodiment includes two vertically placed upright rod assemblies 1, a horizontally arranged transverse connecting rod assembly 2, and a foldable handrail assembly 3. The two upright rod assemblies 1 are symmetrical to each other. The transverse connecting rod assembly 2 is U-shaped, and its two ends are respectively connected and fixed to the two upright rod assemblies 1. The plane of the transverse connecting rod assembly 2 is perpendicular to the two upright rod assemblies 1 and is used to insert between the mattress and the bed board to connect and fix it to the bed frame. The handrail assembly 3 is connected to the top of the two upright rod assemblies 1 and can be flipped and folded outwards to fold and abut against the outer side of the two upright rod assemblies 1 when needed.

[0031] Specifically, the upright rod assembly 1 is formed by connecting and fixing multiple round or square tubular components through connecting elements. The height of two upright rod assemblies 1 is adjustable to accommodate different bed heights. The top of the upright rod assembly 1 is provided with an upper end tube 11. The handrail assembly 3 is formed by connecting and fixing multiple round or square tubular components through connecting elements to form a frame structure. The width of the handrail assembly 3 is adjustable, for example, by inserting pins into different holes on the tubular components to adapt to different usage needs. This handrail assembly in this embodiment can also serve as a bedside guardrail. The bottom of the 3 is provided with two lower end tubes 31, which are respectively adapted to the positions of two upper end tubes 11. The upper end tubes 11 are fixedly connected to the fasteners 6, and the lower end tubes 31 are fixedly connected to the rotating parts 8. The rotating parts 8 and the fasteners 6 are rotatably connected through a folding shaft 7. Specifically, the folding shaft 7 can be fixedly connected to one of the rotating parts 8 or the fasteners 6 (e.g., the rotating parts 8), and simultaneously connected to the other (e.g., the fasteners 6) via a movable pivot, so that the top of the handrail assembly 3 and the two column assemblies 1 can be flipped and folded.

[0032] Furthermore, the handrail assembly 3 is provided with a carrying horizontal pull rod 9, and the two rotating parts 8 are respectively provided with first elongated holes 80 on their opposite inner sides. The two ends of the carrying horizontal pull rod 9 are respectively inserted into the two first elongated holes 80 for limiting, that is, the two ends of the carrying horizontal pull rod 9 can only move up and down within the two first elongated holes 80 to a limited extent; the locking fastener 6 includes a mating limiting part 61 located on the back, a locking positioning groove 62 located on both sides, and a guide ramp part 63 located in front of the locking positioning groove 62; the handrail When component 3 is in the upright and fixed state, the back of the rotating part 8 abuts against the engagement limiting part 61, and both ends of the handle horizontal pull rod 9 are simultaneously located at the bottom of the first elongated hole 80 and the locking positioning groove 62, so that the armrest assembly 3 and the two column rod assemblies 1 are fixedly connected in the same vertical plane, making it convenient for users with mobility impairments to pull on the armrest assembly 3, which is higher than the bed surface, to get up or lie down; when folding is required, the handle horizontal pull rod 9 is lifted upwards, at which time both ends of the handle horizontal pull rod 9 are located at the bottom of the first elongated hole 80. The top part of the armrest assembly 3 completely disengages from the locking slot 62 and flips outward. After rotating 180° around the folding axis 7, the armrest assembly 3 aligns with the outer sides of the two upright rod assemblies 1, completing the folding. At this point, it is recommended that the tops of the two upright rod assemblies 1 not exceed the height of the mattress on the bed, so that the entire foldable get-up aid is located below the mattress and does not occupy the space on the side of the bed. The usage scenario is: after a user with limited mobility pulls on the armrest assembly 3 that is higher than the bed surface to get up, and needs to turn around and move their legs before getting out of bed, they first... The armrest assembly 3 folds without affecting the side space occupied by the bed, making it easy to get out of bed. When returning from the folded state to the upright and fixed state, simply lift the armrest assembly 3. At this time, the two ends of the handle horizontal pull rod 9 slide along the guide ramp 63. When the armrest assembly 3 rotates in the opposite direction about 180° around the folding axis 7, the two ends of the handle horizontal pull rod 9 reach the highest point of the guide ramp 63 and then slide down into the bottom of the locking groove 62. At the same time, the back of the rotating part 8 abuts against the engagement limiting part 61, completing the reset.

[0033] Furthermore, a transverse pin 32 is provided at the upper part of the lower end tube 31, passing through the lower end tube 31. A compression spring 33 is provided in the inner cavity of the lower end tube 31. One end of the compression spring 33 abuts against the transverse pin 32, and the other end is provided with a washer 34 located in the inner cavity of the lower end tube 31. The two lower end tubes 31 are respectively provided with second elongated holes 30 on their opposite inner sides. The second elongated holes 30 are adapted to the first elongated holes 80. The two ends of the handle horizontal pull rod 9 are respectively inserted into the first elongated holes 80 and the second elongated holes 30, and abut against the washer 34, so that the compression spring 33 is compressed between the transverse pin 32 and the washer 34. At the same time, the compression spring... The rebound force of the spring 33 presses both ends of the handle horizontal pull rod 9 against the bottom of the first elongated hole 80 through the washer 34. Only when subjected to an upward pulling force will the two ends of the handle horizontal pull rod 9 move upward within the first elongated hole 80, further pressing against the washer 34, thereby further compressing the compression spring 33. Once the pulling force disappears, the two ends of the handle horizontal pull rod 9 return to the bottom position within the first elongated hole 80, thus enabling the handle horizontal pull rod 9 to have an automatic reset function. When the handrail assembly 3 is in an upright and fixed state, the two ends of the handle horizontal pull rod 9 automatically press against the bottom of the locking groove 62 to prevent it from coming out and improve the safety of use.

[0034] Furthermore, the handrail assembly 3 is equipped with a rotating rod assembly 51, which in turn has an LED lighting module 5. The rotating rod assembly 51 can rotate 360°, allowing the LED lighting module 5 to rotate 360° as well, for adjusting the lighting angle and direction. Users can adjust the light angle as needed to avoid glare when getting up at night and to meet individual preferences for different lighting angles, significantly improving the user's nighttime experience and overall comfort.

[0035] Furthermore, the transverse overlapping rod assembly 2 is fixedly connected to the two upright rod assemblies 1. Alternatively, the transverse overlapping rod assembly 2 can also be quickly detached from the two upright rod assemblies 1 to allow adjustment of the connection height between the transverse overlapping rod assembly 2 and the upright rod assemblies 1, accommodating beds of different heights and thus having a wide range of applications.

[0036] Furthermore, the bottoms of the two column rod assemblies 1 are respectively connected to movable support feet 4, and the movable support feet 4 are connected to the two column rod assemblies 1 in a ball-head-ball-seat manner (e.g., Figure 3 As shown), the movable support leg 4 can rotate within its range of motion; and the relative height between the movable support leg 4 and the two column rod assemblies 1 is adjustable, for example, by using... Figure 3The screw-nut connection shown in this embodiment allows the movable support foot 4 to adapt to various complex terrains and ground environments, such as irregular or sloping ground, ensuring stable support even on complex terrains, thus guaranteeing stability and safety. It can meet the usage needs of different scenarios, providing more personalized support and expanding the applicability of the foldable bed-raising aid. It can provide stable support in various scenarios, including outdoors, on carpets, and on uneven ground, further enhancing its multifunctionality and practicality.

[0037] This invention overcomes the defects and shortcomings of the prior art. The handrail assembly 3 is connected to the tops of the two upright rod assemblies 1 and can be folded outwards. When needed, it folds and aligns with the outer sides of the two upright rod assemblies 1. This changes the fixed handrail design of existing bed-getting aids. After the bed-getting aid is installed on the side of the bed, it avoids the obstruction caused by the handrail blocking the side of the bed when needing to lift legs and turn to get in and out of bed. After the handrail assembly 3 is folded, the side of the bed is basically the same as when the bed-getting aid is not installed, without affecting the space for normal getting in and out of bed, making it more convenient and improving comfort. Therefore, this invention is a convenient bed-getting aid with foldable handrails, which can meet different usage needs.

[0038] This invention can be widely applied in the field of daily care.
