Description

Technical Field

[0001] The utility model relates to the field of auxiliary equipment, in particular to a walking vehicle for preventing the elderly from falling. Background Art

[0002] With the increase of age and the decline of various body functions, more and more elderly people have difficulty walking, and thus need to use auxiliary equipment to maintain daily walking. Elderly people with difficulty walking often use crutches as auxiliary support for daily walking. However, during the use of crutches, they need to be vacant for a period of time when moving forward. For some elderly people who cannot rely on their legs and feet alone, it is easy to fall down during the process of crutches being vacant, thereby causing injuries. The prior art has already produced a walking car that replaces the crutches. The walking car generally includes three parts, namely, a moving wheel, a support frame, and a steering handle arranged from bottom to top. The moving wheel is arranged below the support frame through a bracket, and the steering handle is arranged at the rear of the support frame. In this way, when the elderly with difficulty walking needs to walk, they hold the steering handle to push the walking car as a whole to move. During the movement, the walking car can achieve full support for the elderly to avoid falling. However, in actual use, the existing walking vehicles have a horizontal steering handlebar, and its height is generally adjusted to the same level as the user's wrist height (basically, there is a telescopic rod with a locking device to achieve the height adjustment function). During the forward movement, the elderly need to press down and hold the steering handlebar to achieve the connection with the walking vehicle and control the forward direction (the downward holding here can be understood as the elderly supporting their hands on the steering handlebar and holding the steering handlebar). Long-term downward holding of the handlebar is difficult for the elderly whose grip strength is already poor. At the same time, the downward holding method is not convenient for squeezing the brakes, and the control effect of the walking vehicle on downhill is very limited. If the steering handlebar or brake on any side is not held firmly, it is easy to cause the vehicle to swerve or fall.

[0003] The patent document with the authorization publication number CN214157934U discloses a foldable elderly anti-fall walking trolley; the foldable elderly anti-fall walking trolley includes a moving wheel set, a support leg and a protective frame, and the protective frame includes a crossbar set and a longitudinal bar set, and the crossbar set is rotatably connected with the longitudinal bar set. The crossbar set and the longitudinal bar set in the above patent are equivalent to the above-mentioned direction handle. When using the patented product, the user can support and hold the crossbar set or the longitudinal bar with both hands, and then move forward under the support of the above-mentioned walking trolley. However, the patent still uses a downward-pressing grip method when in use, which is prone to user fatigue, and the technical solution proposed in the patent is very dangerous during downhill and uphill periods.

[0004] In summary, we propose an anti-fall walking vehicle for the elderly to solve the above technical problems. Utility Model Content

[0005] The purpose of the utility model is to provide a fall-proof walking vehicle for the elderly, which can improve the user experience, make it easier and more labor-saving to use, reduce the difficulty of braking for the user, avoid the walking vehicle from tipping over, and provide higher safety.

[0006] The embodiment of the utility model is achieved as follows:

[0007] The embodiment of the present application provides an anti-fall walking vehicle for the elderly, which includes a connecting frame and a walking mechanism arranged on the bottom side of the connecting frame;

[0008] Two symmetrically arranged gripping assemblies are fixedly disposed on the upper end of the connecting frame, and the gripping assemblies include an arm support and a gripping handle fixedly disposed on the connecting frame, and the gripping handle is located in front of the arm support;

[0009] The walking mechanism comprises a plurality of walking units spaced apart along the front-rear direction of the connecting frame, the walking unit comprises a plurality of walking wheels symmetrically distributed on the left and right sides of the connecting frame, and a brake assembly for stopping at least one of the walking units is arranged at the handle.

[0010] In some embodiments of the utility model, the brake assembly includes a brake handle rotatably connected to the handle, the brake handle is connected to a first brake line, the other end of the first brake line is connected to a synchronizer, the other end of the synchronizer is connected to a plurality of second brake lines for controlling the braking of the travel wheels belonging to the same travel unit.

[0011] In some embodiments of the present invention, there are two brake handles, and both of the two brake handles are connected to the synchronizer through the first brake line.

[0012] In some embodiments of the present invention, the connecting frame includes a left frame and a right frame, the left frame and the right frame are fixedly connected via a cross bar, and the two gripping components are respectively located on the left frame and the right frame.

[0013] In some embodiments of the present invention, the cross bar is provided with a storage basket.

[0014] In some embodiments of the present invention, the cross bar is provided with a seat plate.

[0015] In some embodiments of the present invention, the arm support is an arc-shaped plate.

[0016] Compared with the prior art, the embodiments of the present invention have at least the following advantages or beneficial effects:

[0017] An anti-fall walking vehicle for the elderly, comprising a connecting frame and a walking mechanism arranged on the bottom side of the connecting frame;

[0018] Two symmetrically arranged gripping assemblies are fixedly disposed on the upper end of the connecting frame, and the gripping assemblies include an arm support and a gripping handle fixedly disposed on the connecting frame, and the gripping handle is located in front of the arm support;

[0019] The walking mechanism comprises a plurality of walking units spaced apart along the front-rear direction of the connecting frame, the walking unit comprises a plurality of walking wheels symmetrically distributed on the left and right sides of the connecting frame, and a brake assembly for stopping at least one of the walking units is arranged at the handle.

[0020] In the utility model, when using the walking car, the user puts both forearms horizontally on the two arm supports, and then holds the two handles with both hands respectively. At this time, the walking car can move forward under the push of the user, and can provide effective support for the user to prevent the user from falling. Because the user supports the body through the elbows and forearms, it is easier and more labor-saving than the traditional downward-pressing method of pushing the walking car with hands. The support method can also be switched according to the state of the arms and elbows, and it is not easy to get tired. At the same time, because the elbows and forearms are used to achieve the most physical support, the main function of the hand holding the handle becomes to control the direction. The requirement for the tightness of the handle does not need to be as high as that of the existing walking car, which correspondingly reduces the consumption of hand strength, so that the hand can brake more easily and quickly. It should be considered that the arm support provides convenience. While facilitating the walking time, due to the force-bearing mode of its structure (the force-bearing point is higher, and the angle between the force-bearing direction and the gravity direction is larger), compared with the traditional downward-pressing hand-supported walking vehicle, the vertical downward component of the force at the armrest of the utility model is smaller, and the component of force pointing to the oblique front of the walking vehicle is larger, resulting in a higher possibility of the walking vehicle sliding forward, so an effective and sensitive braking system is particularly important. The above-mentioned brake assembly can realize the braking of the walking unit. Taking the most common four walking wheels distributed in a rectangular shape as an example, the two front wheels belong to one brake unit, and the two rear wheels belong to another brake unit. The brake assembly realizes the braking of the two front wheels or the two rear wheels at the same time. Compared with the traditional one-wheel-one-brake structure, it avoids the situation where only the left or right wheel is braked separately, causing the walking vehicle to deviate and overturn, greatly increasing the safety of braking, and reducing the risk of the vehicle falling when braking. The utility model can improve the user experience, is easier and more labor-saving to use, and reduces the difficulty of braking for users, avoiding the overturning of the walking vehicle, and is safer.

[0026] Example

[0027] Please refer to Figure 1-Figure 3 , this embodiment provides an anti-fall walking vehicle for the elderly, which includes a connecting frame and a walking mechanism arranged on the bottom side of the connecting frame;

[0028] Two symmetrically arranged gripping assemblies are fixedly disposed on the upper end of the connecting frame, and the gripping assemblies include an arm support 4 and a gripping handle 5 fixedly disposed on the connecting frame, and the gripping handle 5 is located in front of the arm support 4;

[0029] The walking mechanism comprises a plurality of walking units spaced apart along the front-rear direction of the connecting frame, the walking unit comprises a plurality of walking wheels 13 symmetrically distributed on the left and right sides of the connecting frame, and a brake assembly for stopping at least one of the walking units is provided at the handle 5.

[0030] In the utility model, when using the walking vehicle, the user places both forearms horizontally on the two arm supports 4, and then holds the two handles 5 with both hands respectively. At this time, the walking vehicle can move forward under the push of the user, and can provide effective support for the user to prevent the user from falling. Because the user supports the body through the elbows and forearms, it is easier and more labor-saving than the traditional downward-pressing method of pushing the walking vehicle with hands. The support method can also be switched according to the state of the arms and elbows, and it is not easy to get tired. At the same time, because the elbows and forearms are used to achieve the most physical support, the main function of the hand holding the handle 5 becomes to control the direction. The requirement for the tightness of the handle 5 does not need to be as high as that of the existing walking vehicles, which correspondingly reduces the consumption of hand strength, so that the hand can brake more easily and quickly. It should be considered that the arm supports 4 provide While being convenient and reducing walking time, due to the force-bearing mode of its structure (the force-bearing point is higher, and the angle between the force-bearing direction and the gravity direction is larger), compared with the traditional downward-pressing hand-supported walking vehicle, the vertical downward component of the force at the armrest 4 of the utility model is smaller, and the component of force pointing to the oblique front of the walking vehicle is larger, resulting in a higher possibility of the walking vehicle sliding forward, so an effective and sensitive braking system is particularly important. The above-mentioned brake assembly can realize the braking of the walking unit. Taking the four walking wheels 13 with the most common rectangular distribution as an example, the two front wheels belong to one brake unit, and the two rear wheels belong to another brake unit. The brake assembly realizes the braking of the two front wheels or the two rear wheels at the same time. Compared with the traditional one-wheel-one-brake structure, it avoids the situation that only the left or right wheel is braked separately, causing the walking vehicle to deviate and overturn, greatly increasing the safety of braking, and reducing the risk of the vehicle falling when braking. The utility model can improve the user experience, is easier and more labor-saving to use, and reduces the difficulty of braking for users, avoiding the overturning of the walking vehicle, and is safer.

[0031] It should be noted that the above-mentioned "brake assembly is used to stop at least one of the above-mentioned walking units" can be understood as realizing the simultaneous braking of multiple walking wheels 13 belonging to the same walking unit through the braking action of a single hand. The structure of the brake assembly is the same as the brake assembly of the bicycle in the prior art. Because the bicycle is a single-wheel single-brake achieved by a brake gate, a brake line and a brake pad, a single-wheel single-brake means that a single brake gate controls a single wheel to brake. In order to realize the simultaneous braking of multiple walking wheels 13 by a single brake gate, the brake assembly can be assisted by the technical solution proposed in the patent document "rear brake device" with authorization publication number CN2931279Y on the bicycle brake assembly of the prior art, or it can be assisted by the many-to-many zipper structure in the prior art, such as combining the "zipper" proposed in the patent document with authorization publication number CN217736009U on the basis of the brake assembly of the existing bicycle. The above is only used as an example description of the feasible method based on the technical route of the utility model.

[0032] Optionally, the arm support 4 is connected to the connecting frame by bolt connection. Furthermore, a plurality of clamping holes are provided on the connecting frame. After adjusting the distance between the arm support 4 and the handle 5, the arm support 4 can be fixed to a suitable position of the connecting frame by a bolt group and a locking wrench in cooperation with the nearest clamping hole, thereby increasing the versatility of the utility model. The arm support 4 can also be fixed to the connecting frame by welding. In this way, products with different distances between the arm support 4 and the handle 5 need to be produced during manufacturing to meet the use requirements of different users.

[0033] In some embodiments of the utility model, the brake assembly includes a brake handle 6 rotatably connected to the handle 5, the brake handle 6 is connected to a first brake line 7, the other end of the first brake line 7 is connected to a synchronizer 8, and the other end of the synchronizer 8 is connected to a plurality of second brake lines 9 for controlling the braking of the travel wheels 13 belonging to the same travel unit.

[0034] In the above embodiment, the rotational connection between the handle 5 and the brake lever 6 can be the same as the existing bicycle brake assembly, the number of the above brake lever 6 is at least one, one end of the synchronizer 8 is welded to the inner wire of the first brake wire 7, and the other end is welded to multiple second brake wires 9, and the other ends of the multiple second brake wires 9 are connected to brake pads. When any of the above brake levers 6 is squeezed, due to the action of the synchronizer 8, multiple walking wheels 13 belonging to the same walking unit are braked at the same time, achieving the symmetry of the brake and avoiding the situation of partial vehicle rollover. It should be noted that the brake wire in the prior art includes a plastic sleeve and a metal brake inner wire. The above welding refers to welding with the brake inner wire.

[0035] Optionally, the first brake line 7 and the second brake line 9 are fixed to the connecting frame by means of binding straps, cable ties or clamps welded to the connecting frame to avoid affecting the use of the walking vehicle.

[0036] In some embodiments of the present invention, the number of the brake levers 6 is two, and the two brake levers 6 are connected to the synchronizer 8 via the first brake line 7 .

[0037] Please refer to Figure 3 In the above embodiment, there are two brake handles 6, two traveling units, two traveling wheels 13 belonging to the same traveling unit, the four traveling wheels 13 are distributed in a rectangular shape at the bottom of the connecting frame, and the four traveling wheels 13 are divided into two front wheels and two rear wheels according to different traveling units. In this way, the number of the first brake wires 7 and the second brake wires 9 are both two, which can achieve symmetrical braking of the two front wheels or the two rear wheels at the same time when any brake handle 6 is squeezed. Furthermore, the ends of the two second brake wires 9 away from the synchronization block are respectively close to the two rear wheels.

[0038] In other embodiments of the present invention, the number of the brake handle 6 may be one, that is, one brake handle 6 controls the two rear wheels to stop at the same time.

[0039] In some embodiments of the present invention, the connecting frame includes a left frame body 1 and a right frame body 2, the left frame body 1 and the right frame body 2 are fixedly connected via a cross bar 3, and the two holding components are respectively located on the left frame body 1 and the right frame body 2.

[0040] In the above embodiment, the two handles 5 and the two arm supports 4 are respectively located at the top of the left frame 1 and the top of the right frame 2. The handles 5 and the connecting frame are an integrally formed structure or fixed by welding. The cross bar 3 serves to connect the left frame 1 and the right frame 2, thereby reducing the weight of the utility model. Both ends of the cross bar 3 are fixedly connected to the left frame 1 and the right frame 2 by welding.

[0041] Furthermore, the left frame 1 and the right frame 2 both include a telescopic rod 10, which is used to adjust the height of the arm support 4. The structure of the telescopic rod 10 can refer to any telescopic rod 10 with a locking mechanism in the prior art, which will not be repeated here.

[0042] In some embodiments of the present invention, the cross bar 3 is provided with a storage basket 11 .

[0043] In the above embodiment, the storage basket 11 is fixedly arranged on the front side of the cross bar 3 by means of a bolt group, where the front side here refers to the front side of the walking vehicle.

[0044] In some embodiments of the present invention, the cross bar 3 is provided with a seat plate 12 .

[0045] In the above embodiment, the seat plate 12 is fixed above the cross bar 3 by welding and is located at the rear side of the cross bar 3. When the user wants to take a rest, he can find a structure to lean against and sit down to take a rest.

[0046] In some embodiments of the present invention, the arm support 4 is an arc-shaped plate.

[0047] In the above embodiment, the placement stability of the curved plate is better. Furthermore, a flexible anti-skid pad is arranged above the curved plate.

[0048] In summary, the embodiments of the present invention provide a fall-proof walking vehicle for the elderly, which has at least the following technical effects:

[0049] In the utility model, when using the walking vehicle, the user places both forearms horizontally on the two arm supports 4, and then holds the two handles 5 with both hands respectively. At this time, the walking vehicle can move forward under the push of the user, and can provide effective support for the user to prevent the user from falling. Because the user supports the body through the elbows and forearms, it is easier and more labor-saving than the traditional downward-pressing method of pushing the walking vehicle with hands. The support method can also be switched according to the state of the arms and elbows, and it is not easy to get tired. At the same time, because the elbows and forearms are used to achieve the most physical support, the main function of the hand holding the handle 5 becomes to control the direction. The requirement for the tightness of the handle 5 does not need to be as high as that of the existing walking vehicles, which correspondingly reduces the consumption of hand strength, so that the hand can brake more easily and quickly. It should be considered that the arm supports 4 provide While being convenient and reducing walking time, due to the force-bearing mode of its structure (the force-bearing point is higher, and the angle between the force-bearing direction and the gravity direction is larger), compared with the traditional downward-pressing hand-supported walking vehicle, the vertical downward component of the force at the armrest 4 of the utility model is smaller, and the component of force pointing to the oblique front of the walking vehicle is larger, resulting in a higher possibility of the walking vehicle sliding forward, so an effective and sensitive braking system is particularly important. The above-mentioned brake assembly can realize the braking of the walking unit. Taking the four walking wheels 13 with the most common rectangular distribution as an example, the two front wheels belong to one brake unit, and the two rear wheels belong to another brake unit. The brake assembly realizes the braking of the two front wheels or the two rear wheels at the same time. Compared with the traditional one-wheel-one-brake structure, it avoids the situation that only the left or right wheel is braked separately, causing the walking vehicle to deviate and overturn, greatly increasing the safety of braking, and reducing the risk of the vehicle falling when braking. The utility model can improve the user experience, is easier and more labor-saving to use, and reduces the difficulty of braking for users, avoiding the overturning of the walking vehicle, and is safer.
