Description

Technical Field

[0001] The present invention relates to the field of aging-friendly intelligent assistive devices, and in particular to a device for assisting walking up and down stairs. Background Art

[0002] As the global aging population continues to intensify, the quality of life and health of the elderly have become a focus of social concern. Climbing stairs is an unavoidable part of the elderly's daily lives. For seniors living in multi-story residential buildings in older communities, although some hallways have elevators installed, nearly all use a half-level entry system. This means the elevator landing is level with the stairwell corner landing. After taking the elevator to the landing on the corresponding floor, the elderly must walk up or down a half-level staircase to reach the front door.

[0003] Due to declining physical function, seniors are more likely to lose balance when carrying items up and down stairs (for example, when returning home from shopping), increasing their risk of falls and injuries. While some stair-climbing devices are already available on the market, they often function as simple elevators and fail to fully consider product cost, the need for elderly people to carry items, and their physical needs for stair climbing and walking.

[0004] Existing walking aids are usually independent of the stair handrails, with separate tracks installed, and in the form of seats or pedals, allowing people to ride directly to transport the elderly up and down the stairs. However, on the one hand, such products are extremely expensive, costing 20,000 to 30,000 yuan to run a flight of stairs, which greatly limits their promotion. Secondly, because the elderly need to hold the handrails to maintain their balance, it is still difficult for them to carry items or even a shopping cart while going up and down the stairs. On the other hand, most of the elderly who still live alone in old communities are self-reliant. Moderate stair climbing can ensure their basic daily activity, strengthen their cardiopulmonary function and leg strength, and contribute to their physical and mental health. Therefore, using existing walking aids to directly transport the elderly up and down the stairs is not the best choice. Summary of the Invention

[0005] In order to solve the problems existing in the prior art, the present invention proposes a device for carrying objects up and down the stair handrail. This device can not only provide stable support for the elderly when going up the stairs and reduce the risk of falling, but also can replace the elderly in carrying heavy objects up and down the stairs, thereby enhancing their life autonomy, reducing costs and achieving a wider coverage.

[0006] To achieve the above object, the present invention adopts the following scheme:

[0007] The present invention provides a device for assisting people in carrying objects up and down a stair handrail, which is used to cooperate with the handrail of the stairs. The device comprises a main body and a power part, wherein the main body comprises a main frame, a direction control module, a handhold device and an article carrying module; the power part comprises a traction rope and a drive mechanism; the main frame cooperates with the handrail and moves along the handrail; the direction control module is arranged on the main frame and is used to control the direction of movement of the main frame; the handhold device is arranged on the main frame; the article carrying module is arranged on the main frame and is used to carry articles; wherein the main frame comprises a top connecting member and a first side panel and a second side panel parallel to each other, the first side panel and the second side panel are respectively arranged on both sides of the handrail, and the second side panel is arranged on the side close to the corridor; the top connecting member is connected to the first side panel and the second side panel respectively, and the length of the top connecting member in a direction perpendicular to the side panels is adjustable to accommodate stair handrails of different sizes; one end of the traction rope is connected to the main frame, and the other end is connected to the drive mechanism, so as to provide power for the movement of the main frame.

[0008] In some embodiments, the present invention further includes the following technical features:

[0009] The main frame also includes a shape-adaptive structure, which includes a top wheel combination arranged on the inner side of the top connecting member and a side wheel combination arranged on the inner sides of the first side panel and the second side panel. The top wheel combination slides along the top surface of the armrest, and the side wheel combination slides along the two side surfaces of the armrest. The shape-adaptive structure cooperates with the top connecting member to clamp the armrest from the left, right and top sides, thereby adapting to the sizes and shapes of different armrests.

[0010] The direction control module includes a direction switch, which is arranged above the main frame or on the side close to the corridor. The direction switch has at least two gears, corresponding to the upward and downward movement directions of the main frame along the handrail respectively.

[0011] The item carrying module includes a hook and a storage bag arranged on the outside of the second side panel for hanging and placing items; the item carrying module also includes an L-shaped hanging rod, which has a long side and a short side. When not in use, the long side is stored in the main frame; when in use, the short side cooperates with the hanging hole opened on the second side panel, so that the long side is perpendicular to the second side panel to carry large objects, such as: shopping carts, suitcases, etc.

[0012] The handhold device includes a grip rod hinged to the second side panel. The grip rod is flipped up when no one is using it and does not occupy the normal width of the corridor. It is flipped down when in use and is perpendicular to the second side panel. The grip rod has a built-in start-stop switch module. The button of the start-stop switch module protrudes from the end of the grip rod away from the second side panel. After pressing the button, the main frame switches between the moving state and the stationary state.

[0013] It also includes an infrared obstacle avoidance module, which includes several infrared laser modules. The infrared laser modules are arranged at both ends of the main frame along the handrail direction. When the infrared obstacle avoidance module detects that the main frame runs to both ends of the handrail or encounters an obstacle, it controls the driving mechanism to stop running, so that the main frame stops.

[0014] It also includes a control module, which is arranged on the main frame and is used to remotely control the driving mechanism according to the information obtained by the direction control module, the start-stop switch module, and the infrared obstacle avoidance module.

DETAILED DESCRIPTION

[0033] To make the technical solutions and advantages of the present invention more clear, the technical solutions of the embodiments of the present invention will be fully described below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0034] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0035] The present invention provides an intelligent device combined with a handrail, which meets the needs of carrying objects (maximum load of 15kg) and assisting the elderly to go upstairs. The device comprises three parts: a first part (main body): a main frame structure, an outer shell, a side wheel assembly, a top wheel assembly, a direction switch module, a grip, a start-stop switch module, an infrared obstacle avoidance module, a control module, a battery module, an outer shell, a hook, a storage bag, and an L-shaped hanging rod; a second part (power part): a traction rope, a winch, a coupling, a motor module, a drive module, a power supply module, and a control module; and a third part (anti-rollover part): a hard rod and a handrail connecting member.

[0036] Part 1 (Main body):

[0037] The main frame can be made of hard materials such as plastic, steel, aluminum, etc. The main frame is combined with the specific handrail, and the specific handrail size needs to be considered, and can be prepared in different shapes and sizes;

[0038] The main frame structure is divided into two parts along the left and right sides of the stair handrail. The transverse connecting piece of the main frame structure can be a screw or a hard material with a long hole. The left and right parts of the main frame structure can adjust the distance in the middle by changing the position fixed with the transverse connecting piece, and the handrail is clamped from the left, right and top sides by the side wheel and top wheel combination, so as to adapt to the sizes and shapes of different handrails. The side wheel combination is placed on both sides of the main frame structure, and the number of side wheels on a single side can be 1-10; multiple side wheels are fixed to the main frame structure by screws; the top wheel combination is placed above the main frame structure, and the number of top wheels can be 1-10; multiple top wheels are fixed to the main frame structure by screws; the side wheel combination can slide along the two side surfaces of the handrail, and the positive wheel combination can slide along the top surface of the handrail; after the side wheel combination and the top wheel combination are combined with the two sides and the top of the main frame, they can slide in accordance with the handrail, forming a wheel group activity system that surrounds the handrail from three sides and slides along the handrail;

[0039] The direction switch module can be a switch in various forms such as a button, a rocker, a push button, or a membrane. The direction switch module is placed above the main frame or on the side of the corridor to facilitate control by the elderly. The gear position of the direction switch module corresponds to the movement direction of the device body, for example, gear 1 is the upward direction and gear 2 is the downward direction.

[0040] The grip is placed on the side of the main frame close to the corridor. Its size and height follow the universal design of ergonomic handrails, with a length between 10 cm and 30 cm, and is designed for single-handed grasping. The grip can be made of hard materials such as plastic, steel, and aluminum. The grip flips along its central axis. When not in use, it flips up so as not to occupy the normal width of the corridor. When in use, it flips down and is perpendicular to the side of the main frame for the elderly to grasp from the front. The interior of the grip is hollow and has a built-in start-stop switch module. The button of the start-stop switch module protrudes from the outer end of the grip to adapt to the position of the thumb of the elderly when grasping the grip with one hand. Pressing the start-stop switch module starts the device, and the device body moves along the handrail. Pressing the switch module again stops the device, and the device body stops at the current position.

[0041] The infrared obstacle avoidance module is a device that can emit infrared lasers, with a sensing distance of approximately 1-50 cm and a response speed of approximately 0.1-100 milliseconds. It is also called an infrared laser module. The infrared obstacle avoidance modules are located at both ends of the main frame along the handrail, with a number of 2-10. The infrared obstacle avoidance module is used to determine whether the main part of the device has reached the end of the handrail or detect whether there is an obstacle on the handrail, so as to stop in time to avoid collision. When an obstacle appears within the sensing range of the infrared obstacle avoidance modules placed at both ends of the main frame, the module output signal is converted from high frequency to low frequency, triggering the control module integrated with the main frame to transmit a signal to the control module of the second part (power part) via Bluetooth, causing the motor in the second part (power part) to stop running, achieving the goal of stopping the movement of the first part (main part) before colliding with the obstacle.

[0042] The control module is combined with the main frame and is used to remotely control the direction and status of the motor in the second part (power part) based on the information obtained from the direction switch module, the start-stop switch module, and the infrared obstacle avoidance module. The power module of the main part refers to the module in the main part used to supply power to other modules.

[0043] The shell can be made of hard materials such as plastic and sheet metal; the shell has a relatively simple appearance to cover the main frame and other components connected to the main frame; the shell is connected to the main frame, and the dimensions of the specific main frame and other components connected to the main frame must be considered, and can be prepared in different shapes and sizes;

[0044] The hook is placed on the side of the housing or main frame facing the corridor to facilitate the elderly to hang items (such as shopping bags, etc.); the storage bag is placed on the side of the housing facing the corridor to facilitate the elderly to place scattered items (such as books, water cups, etc.); the L-shaped hanging rod can be made of hard materials such as plastic, steel, aluminum, etc.; one side of the L-shaped hanging rod is shorter and the other side is longer, and the longer side can be 200-500 mm; the L-shaped hanging rod can be stored on the right side of the housing or main frame; when in use, the L-shaped hanging rod can be perpendicular to the right side of the housing or device body, and its purpose is to cooperate with the hook to hang larger items such as shopping carts;

[0045] The second part (power part): The control module remotely receives the direction signal and start-stop signal from the first part (main part) via Bluetooth transmission, directly controls the motor drive module, and thus controls the running direction and running state of the motor module; after receiving the signal, the motor module drives the winch to rotate through the coupling; the material of the traction rope can be ropes or wires of various materials and must be wear-resistant; the length of the traction rope is combined with the specific length of the building section; one end of the traction rope is connected to the main frame or shell of the first part, and the other end is connected to the winch; the rotation of the winch drives the movement of the other end of the traction rope, that is, the movement of the main part; the power module is the module used to supply power to other modules;

[0046] The third part (anti-rollover part): The hard rod is connected to the vertical handrail through a connecting piece and is located below the handrail; after hanging, the force on the side of the main part close to the corridor will be much greater than the other side. Therefore, when the hooks or storage bags of the main part bear too much weight, the main part will tilt toward the side close to the corridor; when the force is uneven and the main part tilts toward the corridor, the bottom end of the main part on the side close to the corridor of the present invention resists the hard rod, dispersing part of the lateral force to the hard rod, avoiding the risk of the main part rolling over due to the load, and constituting the anti-rollover part of the present invention.

[0047] Along the handrail, the main body and wheels clamp directly to the railing, so there is no risk of tilting forward or backward. If rubber-coated wheels are used as side wheels, their own material allows the wheels to clamp the handrail well.

[0048] The present invention is divided into three categories: the main body, the power part, and the anti-rollover part. These three parts are designed separately and interact with each other, which not only meets the use scenario of a single flight of stairs but also reduces manufacturing costs. The present invention realizes the basic combination of the load-carrying device through the unique combination of the pulley block, the housing, and the hard rod.

[0049] The specific embodiments of the present invention are described below:

[0050] Example 1 of the present invention Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 12As shown. Example 1 is the state when the device is mounted with smaller items and the elderly do not need assistance to go upstairs. Before starting the device, it is necessary to first adjust the direction switch module 5 to the corresponding gear, gear one and two correspond to the upward and downward directions respectively, and then place the items in the hook 11 or the storage bag 12. The battery module 10 supplies power to the control module 9 of the first part (main part), so that it can receive, process and send signals; the built-in lithium battery of the battery module 10 ensures the operation of the main part for a long period of time; when the lithium battery of the battery module 10 is out of power, it can be removed for charging, and after it is fully charged, it can be put back into the battery module 10 to continue to power the control module 9. When the start-stop switch module 7 is pressed, the control module 9 of the main part will send a signal to the control module 23 of the power part, which will trigger the operation of the motor module 20 through the drive module 21, and then rotate the winch 18 through the coupling 19, thereby driving the main part of the device connected to the end of the traction rope 17 to slide up or down along the handrail. When the device moves to either end of the handrail, infrared obstacle avoidance module 8 senses the presence of an obstacle, and control module 9 sends a signal to the power unit to stop the device in place. The main frame structure 1 is longer toward the corridor, with its lower end contacting a rigid rod 24. This prevents the device from tipping over if it tilts toward the corridor due to mounting.

[0051] When fixing the hard rod 24, the hard rod 24 is first clamped on the handrail connecting piece 25, and the handrail connecting piece 25 is then clamped on the original vertical railing of the stair handrail.

[0052] like Figure 12 The second side panel 26 is connected to the first side panel 27 through a top connecting piece 31, the side wheel assembly 1 28 and the side wheel assembly 2 29 are respectively arranged on the two side panels, and the top wheel assembly 30 is arranged on the top connecting piece. In some embodiments, the top connecting piece 31 is a screw, and holes are left for the screws on the first side panel 27 and the second side panel 26, so that the distance between the two side panels can be adjusted to better adapt to armrests of different widths.

[0053] Example 2 of the present invention Figure 6 、 Figure 7 、 Figure 8 、 Figure 12As shown. The difference from Example 1 is that the handle 6 combined with the main frame structure 1 rotates around its central axis to open, perpendicular to the front of the device body. Example 2 is the state when the device is mounted with smaller items and the elderly need assistance to go upstairs. Similar to Example 1, before starting the device, it is necessary to first adjust the direction switch module 5 to the corresponding gear position, gears one and two correspond to the upward and downward directions respectively, and then place the items in the hook 11 or the storage bag 12. Open the handle 6 so that it is perpendicular to the front of the device body for the elderly to hold from the front. After the elderly hold the handle 6, they can directly control the start-stop switch module 7 on the handle 6 to ensure the safety of the elderly. The device body (including the handle 6) slides up or down along the handrail. The elderly use the sliding of the handle 6 to reduce their own strength and walk up the stairs more easily.

[0054] like Figure 12 The hollow part 32 inside the grip has a built-in start-stop switch module; the button 33 of the start-stop switch module protrudes from the end of the grip, which adapts to the position of the thumb of the elderly when they grasp the grip with one hand; pressing the start-stop switch module starts the device, and the device body moves along the armrest; pressing the switch module again stops the device, and the device body stops at the current position.

[0055] Example 3 of the present invention Figure 9 、 Figure 10 、 Figure 11 As shown. The difference from Example 1 is that the hanging rod 13 is placed in the hole 15 of the outer shell when the L-shaped hanging rod 13 is used, and the hook 11 is hung on the hanging rod 13. Example 3 is the state when the device is mounting larger items (such as a small shopping cart). At this time, due to the large size of the mounted items, it is not recommended for the elderly to use the auxiliary grip 6 to go upstairs. Similar to Example 1, before starting the device, it is necessary to first adjust the direction switch module 5 to the corresponding gear position, and gear positions one and two correspond to the upward and downward directions respectively. Then take out the hanging rod 13 that was originally placed in the hole 14 of the outer shell for accommodating the L-shaped hanging rod 13, insert it into the hole 15 of the outer shell when the L-shaped hanging rod 13 is used, and hang the hook 11 on the hanging rod 13. Then hang large items (such as a small shopping cart) on the hook 11 on the hanging rod 13. Through the start-stop switch module 7, the main body of the device slides up or down along the handrail.

[0056] According to the present invention, when an elderly person needs to use the main body of the device to carry items, they only need to hang the items on the corresponding hooks or storage pockets, then push the direction switch module to select the direction of up or down, and press the start-stop switch module on the handle. The power part of the device will automatically operate, driving the main body to move. At the same time, the main body can automatically stop when it reaches the end of the handrail. If the elderly person needs the device to assist when climbing stairs, they only need to select the running direction through the direction switch module, flip down the handle, hold the handle, and then press the start-stop switch module on the handle. The device will go up or down according to the instructions. The elderly person can use the handle on the device to reduce their own strength and walk up the stairs more easily. At the same time, the start and stop of the entire device can be controlled by the start-stop switch module on the handle, which also ensures the safety of the elderly.

[0057] The present invention is easy to operate, has little impact on the original corridor space when combined with the handrail, is detachable and movable, and safe to use. Through reasonable material selection, mechanical and electronic design, the present invention can adapt to different stair handrail sizes and carry items of a certain weight, sharing the weight burden of the elderly going up and down the stairs, and at the same time helping the elderly to go up the stairs easily when needed. The present invention is installed on a single-story staircase. Multi-story residential buildings that have been installed with elevators mostly adopt the "half-floor entry" method, that is, the elevator door is connected to the stair landing. When returning home, there is still half a flight of stairs without an elevator, and the elderly need to walk by themselves. Therefore, the present invention is suitable for such multi-story residential buildings that have been installed with elevators. For multi-story residential buildings that have not been installed with elevators, the present invention can also be arranged continuously on each stair section to provide assistance to elderly residents in the entire building.

[0058] In the description of this specification, reference to the terms "one embodiment" and "example" means that the specific features, structures or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present invention. In this specification, the schematic representation of the above terms does not necessarily refer to the relative embodiments or examples in combination in a suitable manner. It must be pointed out that the description of the above embodiments is not intended to be limiting but only to help understand the core idea of ​​the present invention. For ordinary technicians in this technical field, any improvements to the present invention and alternatives equivalent to this product, without departing from the principles of the present invention, also fall within the scope of protection of the claims of the present invention.
