Description

Technical Field

[0001] The present invention relates to a getting-out-of-bed assistive device, in particular to a foldable getting-out-of-bed assistive device. Background Art

[0002] A bed-getting aid is a daily care assistive device, mainly used to help people with limited mobility get up. It is installed on the side of the bed to facilitate people with limited mobility to use the leverage to get up, thereby assisting in getting in and out of bed.

[0003] Currently available bed-raising aids typically only provide basic support functions for getting out of bed, lacking multifunctional designs tailored to individual user needs, making them difficult to meet diverse user scenarios and requirements. For example, existing bed-raising aids often have fixed armrests. When installed on the side of the bed, the armrests block the side of the bed. When lifting legs and turning to get in and out of bed, the armrests can sometimes become obstacles, limiting access and causing inconvenience. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the deficiencies 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, which can meet different usage requirements and solve at least one defect and deficiency in the prior art.

[0005] The technical solution adopted by the present invention is: the present invention includes two vertically placed column rod assemblies, a horizontally arranged transverse overlapping rod assembly, and a foldable handrail rod assembly. The two column rod assemblies are symmetrical to each other, the transverse overlapping rod assembly is U-shaped, and the two ends are respectively connected and fixed to the two column rod assemblies. The plane of the transverse overlapping rod assembly is perpendicular to the two column rod assemblies and is used to be inserted between the mattress and the bed board to be connected and fixed to the bed body. The handrail rod assembly is connected to the top ends of the two column rod assemblies and can be flipped outward and folded so that it can be folded when needed and aligned with the outer sides of the two column rod assemblies.

[0006] An upper end tube is provided at the top of the column rod assembly, and two lower end tubes are provided at the bottom of the handrail rod assembly. The two lower end tubes are respectively adapted to the positions of the two upper end tubes. A clamping piece is fixedly connected to the upper end tube, and a rotating piece is fixedly connected to the lower end tube. The rotating piece and the clamping piece are rotatably connected through a folding axis, so that the handrail rod assembly and the top ends of the two column rod assemblies can be flipped and folded.

[0007] The handrail assembly is provided with a portable transverse pull rod, and the opposite inner sides of the two rotating parts are respectively provided with a first oblong hole, and the two ends of the portable transverse pull rod are respectively inserted into the two first oblong holes for limiting; the clamping piece includes a contact limiting part located on the back, a clamping and fixing groove located on both sides, and a guide slope located in the front of the clamping and fixing groove; when the handrail assembly is in an upright fixed state, the back side of the rotating part abuts against the contact limiting part, and the two ends of the portable transverse pull rod are simultaneously located at the bottom of the first oblong hole and the clamping and fixing groove, so that the handrail assembly and the two column rod assemblies are fixedly connected in the same vertical plane; when it needs to be folded, the portable transverse pull rod is lifted upward When the handrail assembly is rotated 180° around the folding axis, the two ends of the handrail assembly are in contact with the outer sides of the two column assembly to complete the folding. When the handrail assembly is restored to the upright fixed state from the folded state, it is only necessary to lift the handrail assembly. At this time, the two ends of the handrail assembly slide along the guide slope. When the handrail assembly is rotated in the opposite direction by nearly 180° around the folding axis, the two ends of the handrail assembly reach the highest point of the guide slope and then slide down to the bottom of the fixed slot. At the same time, the back side of the rotating part abuts against the abutment limit part to complete the reset.

[0008] The cam is secured to the upper portion of the lower portion of the tube and secured to the lower portion of the tube when the cam is engaged.

[0009] The heights of the two upright rod assemblies are adjustable to adapt to the heights of different beds.

[0010] The width of the handrail assembly can be adjusted to suit different usage requirements.

[0011] The handrail rod assembly is provided with a rotating rod assembly, and the rotating rod assembly is provided with an LED lighting module. The rotating rod assembly can rotate 360 ​​degrees so that the LED lighting module can rotate 360 ​​degrees for adjusting the lighting angle and direction.

[0012] The transverse lap rod assembly and the two vertical column rod assemblies are fixedly connected.

[0013] Alternatively, the transverse lap rod assembly and the two vertical column rod assemblies are connected by a quick-release connection to facilitate adjustment of the position height of the connection between the transverse lap rod assembly and the vertical column rod assembly.

[0014] The bottoms of the two column rod assemblies are respectively connected to movable supporting feet, and the movable supporting feet and the two column rod assemblies are connected in a ball head-ball seat manner, and can be rotated within the range of motion; and the relative height between the movable supporting feet and the two column rod assemblies is adjustable.

[0015] The beneficial effects of the present invention are as follows: since the present invention includes two vertically placed column rod assemblies, a horizontally arranged transverse lap rod assembly, and a foldable handrail rod assembly, the two column rod assemblies are symmetrical to each other, the transverse lap rod assembly is U-shaped, and the two ends are respectively connected and fixed to the two column rod assemblies, the plane of the transverse lap rod assembly is perpendicular to the two column rod assemblies, and is used to be inserted between the mattress and the bed board to be connected and fixed to the bed body, the handrail rod assembly is connected to the top ends of the two column rod assemblies and can be flipped outward and folded so as to be folded and aligned with the outer sides of the two column rod assemblies when needed; the present invention overcomes the defects and shortcomings of the prior art. The armrest rod assembly is connected to the top ends of the two upright rod assemblies and can be flipped and folded outward so as to be folded and aligned with the outer sides of the two upright rod assemblies when needed, thereby changing the inherent mode of the existing armrests of the getting-up aids, in which the armrests are all fixed. After the getting-up aid is installed on the side of the bed, the armrests blocking the side of the bed are avoided, which causes obstacles when lifting the legs and turning around to get in and out of bed. After the armrest rod assembly is flipped and folded, the side of the bed is basically the same as when the getting-up aid is not placed, which does not affect the space for getting in and out of bed normally, making it more convenient to use and improving comfort. Therefore, the present invention is a getting-up aid that is convenient for getting in and out of bed, has foldable armrests, and is easy to use, and can meet different usage needs.

[0030] like Figures 1 to 10 As shown, the foldable bed-getting aid of this embodiment includes two vertically placed column rod assemblies 1, a horizontally arranged transverse overlapping rod assembly 2, and a foldable handrail rod assembly 3. The two column rod assemblies 1 are symmetrical to each other, and the transverse overlapping rod assembly 2 is U-shaped, and the two ends are respectively connected and fixed to the two column rod assemblies 1. The plane of the transverse overlapping rod assembly 2 is perpendicular to the two column rod assemblies 1, and is used to be inserted between the mattress and the bed board to be connected and fixed to the bed body. The handrail rod assembly 3 is connected to the top ends of the two column rod assemblies 1 and can be flipped outward and folded so that it can be folded and aligned with the outer sides of the two column rod assemblies 1 when needed.

[0031] Specifically, the column rod assembly 1 is formed by connecting and fixing a plurality of round or square tubes through connecting elements. The height of the two column rod assemblies 1 can be adjusted to adapt to the height of different beds. The top of the column rod assembly 1 is provided with an upper end tube 11; the handrail rod assembly 3 is formed by connecting and fixing a plurality of round or square tubes through connecting elements to form a frame structure. The width of the handrail rod assembly 3 can be adjusted, for example, by inserting a pin into a socket at different positions on the tube to adapt to different usage requirements. The handrail rod assembly of this embodiment can also serve as a bedside guardrail; the handrail rod assembly 3 is provided with two lower end tubes 31 at the bottom, and the two lower end tubes 31 are respectively adapted to the positions of the two upper end tubes 11. The upper end tube 11 is fixedly connected to the clamping piece 6, and the lower end tube 31 is fixedly connected to the rotating piece 8. The rotating piece 8 and the clamping piece 6 are rotatably connected through a folding shaft 7. Specifically, the folding shaft 7 can be fixedly connected to the rotating piece 8 or one of the clamping pieces 6 (for example, the rotating piece 8), and at the same time be connected to the other one (for example, the clamping piece 6) through a movable pivot, so that the handrail rod assembly 3 and the top ends of the two column rod assemblies 1 can be flipped and folded.

[0032] Furthermore, the handrail assembly 3 is provided with a hand-carrying cross-tie rod 9, and the opposite inner sides of the two rotating parts 8 are respectively provided with first oblong holes 80, and the two ends of the hand-carrying cross-tie rod 9 are respectively inserted into the two first oblong holes 80 for limiting, that is, the two ends of the hand-carrying cross-tie rod 9 can only move up and down within the two first oblong holes 80 to a limited extent; the clamping member 6 includes a contact limiting portion 61 located at the back, a clamping positioning groove 62 located on both sides, and a guiding slope portion 63 located in front of the clamping positioning groove 62; the handrail assembly 3 is provided with a hand-carrying cross-tie rod 9, and a first oblong hole 80 is respectively provided with two opposite inner sides of the two rotating parts 8. When the assembly 3 is in an upright fixed state, the back of the rotating member 8 abuts against the engaging limit portion 61, and the two ends of the portable horizontal tie rod 9 are simultaneously located at the bottom of the first oblong hole 80 and the fixed positioning groove 62, so that the handrail rod assembly 3 and the two column rod assemblies 1 are fixedly connected in the same vertical plane, which is convenient for users with limited mobility to pull the handrail rod assembly 3 above the bed surface to stand up or lie down; when it needs to be folded, the portable horizontal tie rod 9 is lifted upwards, at this time, the two ends of the portable horizontal tie rod 9 are located at the first oblong hole 80 The top of the bed is also completely disengaged from the fixed positioning groove 62, and then turned outward. After the handrail assembly 3 is rotated 180 degrees around the folding axis 7, it is close to the outer sides of the two column rod assemblies 1 to complete the folding. At this time, the tops of the two column rod assemblies 1 are recommended to be no higher than the height of the mattress on the bed, so that the entire foldable bed-getting aid is located below the mattress and does not occupy the space on the side of the bed. The usage scenario can be: after the user with limited mobility pulls up the handrail assembly 3 that is higher than the bed surface and needs to turn around and move his legs before getting out of the bed, he should first put the The armrest rod assembly 3 is folded without affecting the side space occupied by the bed, making it easy to get out of bed; when restoring from the folded state to the upright fixed state, it is only necessary to lift the armrest rod assembly 3. At this time, the two ends of the carrying cross rod 9 slide along the guide slope 63. When the armrest rod assembly 3 rotates in the opposite direction about the folding axis 7 by nearly 180°, the two ends of the carrying cross rod 9 reach the highest point of the guide slope 63 and then slide down to the bottom of the fixed positioning groove 62. At the same time, the back side of the rotating part 8 abuts against the engagement limit part 61 to complete the reset.

[0033] Furthermore, a transverse pin 32 is provided on the upper part of the lower end tube 31 to cross the lower end tube 31, and a compression spring 33 is provided in the inner cavity of the lower end tube 31. One end of the compression spring 33 presses against the transverse pin 32, and the other end is provided with a gasket 34 located in the inner cavity of the lower end tube 31. The opposite inner sides of the two lower end tubes 31 are respectively provided with a second oblong hole 30, and the second oblong hole 30 is adapted to the first oblong hole 80. The two ends of the hand-held cross tie rod 9 are respectively inserted into the first oblong hole 80 and the second oblong hole 30 in turn, and press against the gasket 34, so that the compression spring 33 is compressed between the transverse pin 32 and the gasket 34. At the same time, the compression spring The rebound force of the spring 33 presses the two ends of the carrying cross rod 9 against the bottom of the first oblong hole 80 through the gasket 34; only when subjected to an upward pulling force, the two ends of the carrying cross rod 9 move upward in the first oblong hole 80, further pressing the gasket 34, thereby further compressing the compression spring 33. Once the pulling force disappears, the two ends of the carrying cross rod 9 return to the bottom position in the first oblong hole 80, thereby making the carrying cross rod 9 have an automatic reset function. When the handrail rod assembly 3 is in an upright and fixed state, the two ends of the carrying cross rod 9 automatically press against the bottom of the fixing slot 62 to prevent it from falling out, thereby improving the safety of use.

The rotating rod assembly 51 can rotate 360 ​​degrees, so that the LED lighting module 5 can rotate 360 ​​degrees to adjust the lighting angle and direction. Users can adjust the lighting angle as needed to avoid glare when getting up at night and meet their personal preferences for different lighting angles, significantly improving the user's nighttime experience and overall comfort.

[0035] Furthermore, the transverse lap rod assembly 2 is fixedly connected to the two vertical column rod assemblies 1. In addition, the transverse lap rod assembly 2 and the two vertical column rod assemblies 1 can also be quickly connected to facilitate adjusting the height of the connection between the transverse lap rod assembly 2 and the vertical column rod assembly 1 to accommodate beds of different heights, thus having a wide range of applications.

[0036] Furthermore, the bottoms of the two column rod assemblies 1 are respectively connected to the 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 (such as Figure 3 and the relative height between the movable support foot 4 and the two column rod assemblies 1 can be adjusted, for example, by Figure 3The screw-nut connection method shown; therefore, the movable support foot 4 of this embodiment can adapt to various complex terrains and ground environments such as irregular or inclined ground, ensure that the support remains firm on complex terrain, ensure stability and safety, and can meet the use requirements of different scenarios, provide more personalized support and fixation, and expand the scope of application of the foldable getting-up aid, including providing stable support in various scenarios such as outdoors, carpets and uneven ground, further improving versatility and practicality.

[0037] The present invention overcomes the defects and shortcomings of the prior art. The armrest rod assembly 3 is connected to the top ends of the two column rod assemblies 1 and can be flipped and folded outward so as to be folded and aligned with the outer sides of the two column rod assemblies 1 when needed, thereby changing the inherent mode of the existing armrests of the getting-up aids, in which the armrests are all fixed. After the getting-up aid is installed on the side of the bed, the armrests blocking the side of the bed are avoided, which causes obstacles when lifting legs and turning to get in and out of bed. After the armrest rod assembly 3 is flipped and folded, the side of the bed is basically the same as when the getting-up aid is not placed, and the space for normal getting in and out of bed is not affected. The use is more convenient and the comfort is improved. Therefore, the present invention is a getting-up aid that is convenient for getting in and out of bed, has foldable armrests, and is easy to use, which can meet different usage needs.

[0038] The present invention can be widely applied to the field of daily care.
