Description

Technical Field

[0001] This utility model relates to the field of elderly care, and more specifically, to a fall-preventing nursing bed for elderly care. Background Technology

[0002] Currently, nursing bed guardrails have some limitations. Folding guardrails have a fixed height and must be fully lowered during nursing procedures, at which point they lose their protective function. If they are forgotten to raise them after the procedure, the risk of falls for the elderly is greatly increased. Some lift-type guardrails can be infinitely adjusted in height, but they lack height memory and function indicators. Caregivers cannot quickly and accurately adjust the guardrails to the heights corresponding to protection and nursing procedures. Each adjustment requires repeated attempts, which is cumbersome and prone to errors. This not only affects nursing efficiency but also makes it difficult to ensure continuous fall protection for the elderly.

[0003] How to invent a fall-preventing nursing bed for the elderly to improve these problems has become an urgent issue for those skilled in the art. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a fall-proof nursing bed for elderly care, aiming to improve the problems of folding guardrails which require complete lowering during care, thus losing protection, and the risk of falling due to forgetting to raise them, as well as the problems of some lifting guardrails which have stepless adjustment but lack height memory and function indicators, and whose adjustment is cumbersome and difficult to accurately correspond to the protection and care height.

[0005] This utility model is implemented as follows: a fall-prevention nursing bed for elderly care includes a bed frame, on both sides of which memory lifting guardrails are slidably provided. Each memory lifting guardrail includes several vertical bars evenly and parallelly distributed along the length of the bed frame. The tops of the vertical bars are fixedly connected to the bottom surface of the crossbeam. Each vertical bar is slidably installed in corresponding insertion holes opened on both sides of the bed frame. Limiting mechanisms are provided inside both sides of the bed frame. Two height memory marker blocks are slidably provided on one of the vertical bars along its extension direction, and each height memory marker block is provided with an independent limiting structure.

[0006] In a preferred embodiment of this utility model, each of the limiting mechanisms includes a displacement carrier plate, which is slidably installed in a mounting groove. The mounting groove is located inside the two side frames of the bed and extends along the length of the bed. The displacement carrier plate slides in the mounting groove along the width direction of the bed. Each insertion hole is connected to the mounting groove on the side facing the insertion hole. A stop-limiting block is provided on the surface of the displacement carrier plate facing the insertion hole for each insertion hole. One end of a limiting screw is rotatably installed on the other side surface of the displacement carrier plate. Mounting seats are provided on both sides of the bed frame. A threaded hole is provided on one end of each mounting seat, which extends through to the corresponding mounting groove. The limiting screw is threaded into the corresponding threaded hole, and a knob is provided on the other end.

[0007] In a preferred embodiment of this utility model, guide slide rods are integrally provided at both ends of the side surface of the displacement carrier plate facing the insertion hole. Each guide slide rod is slidably installed in a corresponding guide limiting slide hole, and two guide limiting slide holes on each side are provided in the crossbeam of the bed frame.

[0008] In a preferred embodiment of this utility model, an adjustment groove is formed on one side surface of the vertical rod with the height memory marker block along its extension direction. Each height memory marker block is integrally formed on the outer surface of the corresponding base block. A protrusion is integrally formed on the rear end of both sides of the base block. The base block is slidably installed in a receiving groove formed on one side surface of the slider. A retaining spring is fixedly connected between the inner wall of one side of the receiving groove and the rear surface of the base block. An anti-slip pad is provided on the side surface of each protrusion facing the height memory marker block.

[0009] In a preferred embodiment of this utility model, the overall structure of the adjusting slide, the height memory marker block, the base block, and the protrusion is a T-shaped cross section, and anti-slip pads are also provided on the inner wall of the opening of the adjusting slide on the side facing the protrusion.

[0010] In a preferred embodiment of this invention, the surfaces of the two height memory marker blocks are coated with coatings of different colors.

[0011] In a preferred embodiment of this utility model, the outer surface of the height memory marker block is coplanar with the outer surface of the vertical rod.

[0012] The beneficial effects of this utility model are as follows: The nursing bed for elderly care that prevents falls, obtained through the above design, allows for stable suspension and convenient adjustment of the guardrail at any height via a limiting mechanism. It requires no electrical components, ensuring high reliability. Caregivers can easily switch between locked and unlocked states using a knob, avoiding the problem of loss of protection when the folding guardrail is fully lowered. Secondly, the height memory marking blocks, through mechanical friction limiting, can separately mark the heights corresponding to protection and care operations. Different colored coatings facilitate quick identification, achieving a high-efficiency balance between protection and care operations. This ensures the safety of the elderly from falls while improving the efficiency of care operations. The structure is simple and practical. Attached Figure Description

Detailed Implementation

[0016] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0017] Please see Figures 1 to 6 This utility model provides a technical solution: a fall-prevention nursing bed for elderly care, including a bed body 1, with memory lifting guardrails 2 slidably arranged on both sides of the bed body 1. Each memory lifting guardrail 2 includes several vertical rods 201 evenly and parallelly distributed along the length of the bed body 1. The top ends of the vertical rods 201 are fixedly connected to the bottom surface of the crossbeam 202. Each vertical rod 201 is slidably installed in corresponding insertion holes 101 opened on both sides of the bed body 1 frame. Limiting mechanisms are provided inside both sides of the bed body 1 frame. Two height memory marker blocks 204 are slidably arranged on one of the vertical rods 201 along its extension direction, and each height memory marker block 204 is provided with an independent limiting structure.

[0018] Bed Frame 1 utilizes the basic structure of existing nursing beds, with several high-strength alloy support legs fixedly welded to its bottom. The ends of these legs are fitted with casters equipped with brake locking functions via bearings. This allows caregivers to flexibly move the bed according to usage scenarios, while locking the brakes ensures the bed remains stable and does not slide. The bed board of Bed Frame 1 features a segmented design, with built-in mechanical linkages or hydraulic drive mechanisms enabling angle adjustment of the back and leg panels. This allows for flexible adaptation to different needs of the elderly, such as lying down for rest, sitting for eating, or semi-recumbent rehabilitation. The main body of Bed Frame 1 uses a high-strength alloy frame to ensure stable support for the elderly. Precision CNC-machined insertion holes 101 on both sides are matched to the vertical rod 201, ensuring smooth vertical lifting and sliding of the vertical rod 201. Several vertical bars 201 are welded together with a crossbeam 202 to form an integral memory lifting guardrail 2, which can be freely raised and lowered along the insertion hole 101. The limiting mechanism in the frame of the bed 1 cooperates with the vertical bars 201 to achieve the guardrail being suspended and locked at any height. Two height memory marker blocks 204 configured on one of the vertical bars 201 can be adjusted to a fixed position in any direction of the vertical bar 201 through an independent limiting structure, respectively accurately corresponding to the daily protection height and the nursing operation height. Caregivers do not need to repeatedly measure or fine-tune, but can quickly identify and adjust to the target height simply by using the marker blocks.

[0019] Please see Figures 2 to 6Each limiting mechanism includes a displacement carrier plate 103, which is slidably installed in the mounting groove 102. The mounting groove 102 is opened inside the frame on both sides of the bed body 1 and extends along the length of the bed body 1. The displacement carrier plate 103 slides in the mounting groove 102 along the width direction of the bed body 1. Each insertion hole 101 is connected to the mounting groove 102 on the side facing the insertion hole 101. A stop limiting block 104 is provided on the surface of the displacement carrier plate 103 facing the insertion hole 101, corresponding to the position of each insertion hole 101. One end of the limiting screw 107 is rotatably installed on the other side of the displacement carrier plate 103. Mounting seats are provided on both sides of the frame of the bed body 1. A threaded hole is opened on one end of each mounting seat through to the corresponding mounting groove 102. The limiting screw 107 is threadedly connected to the corresponding threaded hole and a knob 108 is provided on the other end.

[0020] The mounting slots 102 are milled within the side frames of the bed frame 1. The displacement carrier plate 103 is made of wear-resistant steel, with minimal sliding clearance between it and the mounting slots 102. The abutment limiting blocks 104 are integrally formed with the displacement carrier plate 103, their number corresponding one-to-one with the insertion holes 101, and their end faces are equipped with abutment rubber blocks. When the knob 108 is rotated, the limiting screw 107 rotates within the threaded hole, pushing the displacement carrier plate 103 to slide along the width of the bed frame 1, allowing the abutment limiting blocks 104 to enter and exit the insertion holes 101. During engagement, friction is used to achieve arbitrary height suspension and fixation of the guardrail; during disengagement, the guardrail can be freely raised and lowered. No electrical components are required, ensuring high reliability. Caregivers can easily switch between locking and unlocking via the knob 108, solving the problems of complex or cumbersome operation in existing guardrail locking structures. This achieves stable suspension and convenient adjustment at any height, ensuring the safety of the elderly and facilitating height adjustment for nursing care.

[0021] Furthermore, guide slide rods 105 are integrally provided at both ends of the side surface of the displacement plate 103 facing the insertion hole 101. Each guide slide rod 105 is slidably installed in the corresponding guide limiting slide hole 106, and two guide limiting slide holes 106 on each side are provided in the crossbeam of the bed frame 1.

[0022] The guide slide rod 105 is welded to the displacement carrier plate 103 and is made of wear-resistant material. The guide limiting slide hole 106 is precisely machined on the crossbeam of the bed frame 1 and slides in cooperation with the guide slide rod 105. The double guide structure ensures that the displacement carrier plate 103 is always horizontal when sliding, avoiding tilting or jamming, and ensures that the abutment limiting block 104 accurately enters and exits the insertion hole 101, and reliably abuts or disengages from the vertical rod 201. This improves the working reliability of the limiting mechanism, makes the guardrail height locking more stable, and will not cause limiting failure due to structural displacement during long-term use.

[0023] Furthermore, an adjustment groove 203 is provided on one side surface of the vertical rod 201 with height memory marker block 204 along its extension direction. Each height memory marker block 204 is integrally set on the outer surface of the corresponding base block 205. Both rear ends of the two sides of the base block 205 are integrally provided with protrusions 206. The base block 205 is slidably installed in the receiving groove 208 opened on one side surface of the slider 207. A clamping spring 209 is fixedly connected between the inner wall of one side of the receiving groove 208 and the rear surface of the base block 205. Each protrusion 206 is provided with an anti-slip pad on the side surface facing the height memory marker block 204.

[0024] The adjusting slide 203 is milled into a T-shaped cross-section along the vertical rod 201. The base block 205 and the height memory marker block 204 are integrally formed. The protrusions 206 are symmetrically arranged on both sides of the base block 205. The receiving groove 208 of the slider 207 slides in conjunction with the base block 205. The clamping spring 209 is made of spring steel. During adjustment, the height memory marker block 204 is pressed into the adjusting slide 203, compressing the clamping spring 209, causing the anti-slip pad of the protrusion 206 to separate from the inner wall of the slide. The marker block can be slid to the desired height. After releasing, the spring returns to its original position, and the anti-slip pad re-engages at the limit position. This allows the marker block to be adjusted to any position, corresponding to protection and care heights. Caregivers can quickly adjust the guardrail by using the position of the marker block, solving the problem of finding the commonly used height when there are no markers. The purely mechanical structure is reliable, simple to operate, and improves care efficiency.

[0025] Furthermore, the overall structure of the adjusting slide 203, the height memory marker block 204, the base block 205, and the protrusion 206 is a T-shaped cross section, and anti-slip pads are also provided on the inner wall of the opening of the adjusting slide 203 on the side facing the protrusion 206.

[0026] The entire structure formed by the adjusting slide 203, height memory marker block 204, base block 205, and protrusion 206 has a T-shaped cross-section, ensuring that the marker block does not fall off during sliding. High-friction coefficient rubber anti-slip pads are provided on the inner walls of both sides of the opening of the adjusting slide 203 and the surface of the protrusion 206. When these two surfaces are in contact, sufficient friction is generated, preventing the marker block from sliding due to vibration or collision after adjustment, thus ensuring accurate height memory. This improves the reliability of the marker block's limit position, ensuring stable maintenance of the set height over long-term use. It provides caregivers with a continuously accurate height reference, ensuring precise height switching of the guardrail in both protective and nursing scenarios.

[0027] Furthermore, the surfaces of the two height memory marker blocks 204 are coated with different colors.

[0028] The two height memory indicator blocks 204 are coated with different eye-catching colors, red and blue, respectively. Red corresponds to the daily protection height, and blue corresponds to the nursing operation height. Through the visual difference in color, caregivers can identify the height indicators of different functions from a distance or with a quick glance, without the need for close observation or touching. This improves the efficiency and accuracy of height switching, especially in low light conditions or when caregivers are busy. The color indicators can quickly convey information, avoid adjustment errors, and ensure the safety of the elderly and the convenience of nursing operations.

[0029] Furthermore, the outer surface of the height memory marker block 204 is coplanar with the outer surface of the vertical bar 201.

[0030] When the height memory marker block 204 is in the limit position, its outer surface is coplanar with the outer surface of the vertical bar 201. This makes the overall appearance of the guardrail flat, avoids the marker block protruding and causing scratches, and ensures the safety and comfort of the elderly. At the same time, it makes it easy for caregivers to adjust the height of the guardrail without the marker block protruding and causing obstruction, thus achieving a balance between function, safety, and aesthetics.

[0031] Working principle: The memory lifting guardrail 2 is adjusted by vertically sliding the vertical rod 201 through the insertion hole 101 in the bed frame 1. During adjustment, the displacement plate 103 in the mounting groove 102 of the bed frame 1 slides smoothly under the guidance of the guide slide rod 105 and the guide limiting slide hole 106. The caregiver drives the limiting screw 107 to rotate by rotating the knob 108, which in turn pushes the displacement plate 103 to move along the width direction of the bed frame 1, so that the abutment limiting block 104 moves in and out of the insertion hole 101. When the abutment limiting block 104 abuts against the surface of the vertical rod 201, the friction force is used to achieve the suspension and locking of the memory lifting guardrail 2 at any height. When the abutment limiting block 104 disengages from the vertical rod 201, the guardrail can be raised and lowered freely. At the same time, the vertical rod 201 near the knob 108 adjusts the two height memory indicators installed in the sliding groove 203. Block 204 can be compressed by pressing the clamping spring 209, causing the base block 205 to move the protrusion 206 away from the anti-slip pad on the inner wall of the adjusting slide 203, and then slide to the preset daily protection height and nursing operation height. After releasing, the clamping spring 209 returns to its original position, and the protrusion 206 and the anti-slip pad on the inner wall of the adjusting slide 203 re-abut against each other to form a limit. The T-shaped cross-section structure ensures that the marking block does not fall off. With the visual distinction of different colored coatings, caregivers can quickly judge and adjust the guardrail to the target height by the relative position of the height memory marking block 204 and the edge of the bed frame 1. No electrical components are required throughout the process. The guardrail can be suspended at any height, and the commonly used height can be memorized and quickly switched only through mechanical transmission and friction limit. This not only ensures the fall protection effect for the elderly, but also simplifies the nursing operation process and improves care efficiency and reliability.

[0032] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
