Description

Technical Field

[0001] This utility model relates to the technical field of elevators, and in particular to an accessible assistive dining table for the elderly. Background Technology

[0002] Currently, the elderly often face numerous inconveniences in their daily lives, such as difficulty picking up food due to hand tremors, joint degeneration making it difficult to adapt to tables of fixed height, and difficulty getting up to pick up food due to declining physical function. Elderly people living alone also need to carry hot soup and meals alone, posing safety hazards. Studies show that 72% of elderly people experience a more than 30% increase in mealtime due to unsuitable table design, while frequent spills exacerbate the cleaning burden and psychological stress. Existing age-friendly furniture often remains at the "downsizing" stage—simply lowering the height or adding anti-slip accessories—without directly addressing the complexity of the overall functional decline in the elderly. Therefore, multifunctional, barrier-free assistive dining tables for the elderly play a crucial role in supporting their daily lives. Utility Model Content

[0003] This utility model provides an accessible assistive dining table for the elderly, which solves the problems of existing age-friendly dining tables having a fixed height and not being able to be adjusted according to the elderly's dining posture.

[0004] This utility model can be achieved through the following technical solutions:

[0005] An accessible assistive dining table for the elderly includes a plate, which is mounted on a tabletop via a rotating and moving mechanism. One end of the bottom surface of the tabletop is connected to a mobile trolley via a lifting mechanism.

[0006] The lifting mechanism adopts a nested structure to drive the tabletop and the plate to move up and down.

[0007] The rotary moving mechanism is used to drive the plate to rotate and can move linearly along the tabletop.

[0008] The mobile cart is used to move the accessible dining table for the elderly autonomously.

[0009] Furthermore, the rotary movement mechanism includes a transition plate, on which a Geneva mechanism is provided that cooperates with each other. The central axis of the driving wheel of the Geneva mechanism is connected to the output shaft of the first motor, and the top surface of its driven wheel is connected to the dinner plate.

[0010] The first motor is used to drive the plate to rotate intermittently via a grooved wheel mechanism;

[0011] The bottom surface of the adapter plate is provided with multiple linear slide rails, and one side of the adapter plate has a folded edge. The outer surface of the folded edge has a rack-like structure, which meshes with a transmission gear. The central axis of the transmission gear is connected to the output shaft of the second motor.

[0012] The second motor is used to drive the plate to move linearly along the tabletop through the meshing of transmission gears and rack-like structures.

[0013] Furthermore, a movable guide groove is provided on the tabletop, through which the plate passes and is connected to the driven wheel of the Geneva wheel mechanism;

[0014] The movable guide groove, linear slide rail, and folded edge are all arranged along the length direction of the desktop panel.

[0015] Furthermore, the plate has a circular structure and is divided into sections.

[0016] Furthermore, the lifting mechanism includes nested inner and outer square tubes. The free end of the inner square tube is connected to the desktop, and the free end of the outer square tube is connected to the moving trolley. A ball screw is installed inside the mechanism. One end of the screw rod of the ball screw is connected to the output shaft of a third motor, and its screw nut is connected to the non-free end of the inner square tube.

[0017] The third motor is used to drive the ball screw to rotate, thereby driving the inner square tube to move up and down relative to the outer square tube, which in turn drives the tabletop and the plate to move up and down.

[0018] Furthermore, the upper end of the inner square tube is provided with a support rod extending toward the center of the desktop.

[0019] Furthermore, the screw is also fitted with a four-legged connector, the central position of which is provided with a through hole that engages with the screw thread, and the four legs around it are respectively connected to the four walls of the inner square tube.

[0020] Furthermore, the mobile trolley has an overall T-shaped structure, with a drive wheel at each of the two ends of the bottom surface of its horizontal section, a lifting mechanism at the top surface of its horizontal section, and drive wheels at the ends of its vertical section.

[0021] Furthermore, the plate is positioned in the center of the tabletop, with two arm supports on each side, and these arm supports are detachably mounted on the tabletop.

[0022] Furthermore, multiple operation buttons are provided on one pair of opposite corners of the desktop panel, and L-shaped notches are provided on the other pair of opposite corners.

[0023] Two slots are provided at intervals on one side of the desktop panel for placing daily necessities.

[0024] The beneficial technical effects of this utility model are as follows:

[0025] 1. With the help of a mobile cart, the barrier-free assistive dining table for the elderly of this utility model can be moved autonomously to the target location as needed, facilitating food delivery without requiring the elderly to manually carry the food. At the same time, with the help of the lifting mechanism, the height of the tabletop can be automatically adjusted to accommodate the different posture requirements of the elderly while eating. Using the rotating moving mechanism, the plate can be moved to different positions on the tabletop to reduce the difficulty for the elderly in the corresponding position to get up and pick up food. Furthermore, the food in different positions on the plate can be rotated to the elderly in the current position to improve the convenience of dining and give the elderly a better dining experience.

[0026] 2. The use of a Geneva mechanism enables the intermittent rotation of the plate. Combined with the partitioning on the plate, food from different areas can be moved to the elderly person as the plate rotates, improving the convenience of dining. Compared to the continuous rotation of a gear transmission structure, the intermittent rotation of the Geneva mechanism is more suitable for dining needs and can greatly reduce the complexity of control.

[0027] 3. By cleverly using the adapter plate with folded edges, the rotating structure of the rotary moving mechanism, namely the grooved wheel mechanism, and the moving structure, namely the linear slide rail, transmission gear and rack, are combined together. The whole structure is very compact, highly practical, and can better utilize the internal space of the desktop.

[0028] 4. The T-shaped mobile cart, lifting mechanism, and tabletop form the overall C-shaped structure of the dining table. When the elderly need to eat in bed, the side of the mobile cart with a single drive wheel can be inserted under the bed, while the tabletop is displayed on the bed, improving the convenience of dining and expanding its application range.

[0029] This utility model of an accessible assistive dining table for the elderly is simple to operate, inexpensive, and easy to promote and apply. Attached Figure Description

Detailed Implementation

[0038] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.

[0039] See attached document Figure 1 , 2 This invention provides an accessible assistive dining table for the elderly, including a plate 1. The plate 1 is mounted on a tabletop 2 via a rotating and moving mechanism. One end of the bottom surface of the tabletop 2 is connected to a moving trolley 4 via a lifting mechanism 3. The lifting mechanism 3 has a nested structure and is used to move the tabletop 2 and the plate 1 up and down to adjust their height. The rotating and moving mechanism is used to rotate the plate 1 and move it linearly along the tabletop 2. The moving trolley 4 is used to move the accessible assistive dining table autonomously. Driven by the moving trolley, the accessible assistive dining table can move autonomously to its destination as needed, facilitating food delivery. Simultaneously, the lifting mechanism automatically adjusts the height of the tabletop to accommodate different posture requirements of elderly people while eating. The rotating and moving mechanism allows the plate to be moved to different positions on the tabletop, reducing the difficulty for elderly people in those positions to get up and pick up food. Furthermore, food from different positions on the plate can be rotated to the elderly person in the current position, improving dining convenience and providing a better dining experience. In addition, this accessible assistive dining table is simple to operate, low in cost, and easy to promote and apply.

[0040] Specifically as follows:

[0041] The desktop panel 2 has a flat rectangular structure with internal storage space. A movable guide groove 21 is provided in the center of the desktop panel 2 along the length direction. The plate 1 passes through the movable guide groove 21 and is connected to the rotating moving mechanism. The rotating moving mechanism can be set inside the desktop panel 2 to improve aesthetics.

[0042] like Figure 3As shown, the rotating moving mechanism includes a transition plate 22, on which a grooved wheel mechanism 23 is provided to cooperate with each other. The grooved wheel mechanism 23 can be an external grooved wheel mechanism. The central shaft of its driving wheel is connected to the output shaft of the first motor, and the top surface of its driven wheel is connected to the plate 1. The first motor is used to drive the plate 1 to perform intermittent rotational motion through the grooved wheel mechanism 23. The plate 1 can be divided into sections, and the angle of the sections can be consistent with the intermittent rotation angle of the plate 1, thereby facilitating the rotation and adjustment of the food on the plate 1.

[0043] The bottom surface of the adapter plate 22 is provided with multiple linear slide rails 24, and one side of it is provided with a folded edge 221. They are aligned with the direction of the moving guide groove. The outer surface of the folded edge 221 has a rack-like structure, which meshes with the transmission gear 25. The central axis of the transmission gear 25 is connected to the output shaft of the second motor. The second motor is used to drive the plate 1 to move linearly along the tabletop 2, that is, along the moving guide groove 21, through the meshing of the transmission gear 25 and the rack-like structure. This allows the plate 1 to be moved to other positions on the tabletop 2 in front of the elderly without them having to get up to pick up the food.

[0044] like Figure 4-5 As shown, the lifting mechanism 3 includes an inner square tube 31 and an outer square tube 32 nested together. The free end of the inner square tube 31 is connected to the tabletop, and the free end of the outer square tube 32 is connected to the moving trolley 4. A ball screw 33 is installed inside them. One end of the screw in the ball screw 33 is connected to the output shaft of the third motor, and its screw nut is connected to the non-free end of the inner square tube 31. In this way, when the third motor drives the ball screw 33 to rotate, it can drive the inner square tube 31 to move up and down relative to the outer square tube 32, thereby driving the tabletop 2 and the plate 1 to move up and down to adjust the height of the tabletop 2, which is suitable for the elderly to dine in different postures.

[0045] To ensure the stable operation of the ball screw 33, a four-legged connector 34 is also fitted on its screw. The four-legged connector 34 has a through hole in the center that mates with the screw thread, and its four legs are respectively connected to the four walls of the inner square tube 31.

[0046] Considering that the lifting mechanism not only adjusts the height of the desktop but also supports it, the upper end of our inner square tube 31 is provided with a support rod 35 extending towards the center of the desktop 2. These can be designed as an integrated unit to better support the desktop.

[0047] like Figure 6As shown, the mobile trolley 4 has a T-shaped structure. A drive wheel 41 is provided at each of the two ends of the bottom surface of its horizontal part, a lifting mechanism 3 is provided on the top surface of its horizontal part, and a drive wheel 41 is also provided at the end of its vertical part. Thus, the barrier-free assistive dining table for the elderly of this utility model has a C-shaped structure. When the mobile trolley brings the barrier-free assistive dining table for the elderly to the bedside of the elderly, the side with the single drive wheel can be inserted under the bed, and the tabletop can be displayed on the bed to facilitate the elderly to eat in bed.

[0048] Of course, the drive wheel at the end of the vertical part can be replaced by a caster wheel 42. When the elderly can move the barrier-free assisted dining table, the drive wheel 41 is in front and the caster wheel 42 is behind to ensure straight movement. When it is about to reach the destination, the whole thing rotates 180° so that the side where the caster wheel 42 is located can be inserted into the bottom of the bed, thereby straightening the tabletop.

[0049] In addition, two arm supports 5 are installed on each side of the plate 1 on the tabletop 2, such as... Figure 7 As shown, these arm supports 5 can be detachably mounted on the tabletop 2, such as a magnetic structure, and can rotate freely relative to the tabletop 2, making it convenient for elderly people with hand tremors to place their arms on the arm supports 5 while eating, reducing the impact of hand tremors on eating.

[0050] Multiple operation buttons 26 are provided on one pair of opposite corners of the desktop panel 2, and L-shaped notches 27 are provided on the other pair of opposite corners. Two slots 28 are provided at intervals on one side of the desktop panel for placing daily necessities such as canes.

[0051] This utility model of an accessible assistive dining table for the elderly integrates multiple age-friendly functions, enabling it to assist elderly people living alone or with limited mobility with their meals, while also possessing a stable structure and good functionality.

[0052] While specific embodiments of the present invention have been described above, those skilled in the art should understand that these are merely illustrative examples. Various changes or modifications can be made to these embodiments without departing from the principles and essence of the present invention. Therefore, the scope of protection of the present invention is defined by the appended claims.
