Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of medical devices and protective articles, and particularly relates to a multifunctional anti-falling walking aid. BACKGROUND

[0002] With the arrival of an aging society, many problems are in front of the society and family, and almost every family will face the problem of the elderly in the family being unable to move and needing care. For the elderly, falling is almost an unexpected risk that they cannot afford, and almost all falls of the elderly will lead to fractures. Once fractured, it is basically a disaster, and many people will lose their ability to live independently or even their lives. In addition to natural aging factors, some people will also have lower limb weakness or inconvenience in movement due to diseases (such as stroke) or accidents. The necessary rehabilitation, exercise, bathing, and toilet activities of these people are difficult to complete independently or are prone to falling without care and help. For many families, long-term follow-up care and care is a heavy burden in terms of economy and energy.

[0003] If there is a device or apparatus that can enable these people to complete the above activities independently without the help of others, even to self-care other behaviors of life without the risk of falling, it will greatly improve the quality of life of these patients, and will greatly reduce the burden and worry of their families and relatives.

[0004] Although there are currently many walking aids or wheeled crutches, they can all help lower limb disabled patients to share part of the body weight and assist in supporting the body when walking to varying degrees, but they cannot effectively prevent patients from falling.

DETAILED DESCRIPTION

[0040] The application will be further described below in connection with the embodiments shown in the drawings.

[0041] As shown in the drawings, Figure 1 a multifunctional fall-prevention walking aid, characterized in that it comprises:

[0042] a base frame 100, which is composed of a left bottom rod 130, a front bottom rod 140 and a right bottom rod 150 to form a "Fang" shape, and a plurality of casters 110 are arranged on the lower side of the base frame 100;

[0043] a plurality of support columns 300, the lower ends of which are fixedly arranged on the base frame 100;

[0044] The frame 200 is provided at the upper end of the support 300, and the frame 200 is composed of a left support 210, a rear support 230 and a right support 220 to form a "Fang" shape, and the door bar 240 is provided at both ends of the frame 200 to form a closed loop frame shape with the frame 200.

[0045] The sling 400 includes a left sling 410, a right sling 420 and a rear sling 430, and the lower ends of the left sling 410, the right sling 420 and the rear sling 430 are connected to the three corners of the triangular frame lifting seat 500, and the upper ends of the left sling 410, the right sling 420 and the rear sling 430 are connected to the left support 210, the right support 220 and the rear support 230 of the frame 200, respectively, and the leg fixing belt 510 is provided at the positions where the triangular frame lifting seat 500 is connected to the left sling 410 and the right sling 420.

[0046] When the anti-falling walking aid vehicle is used, the user stands in the three-dimensional frame structure composed of the base frame 100, the support 300, the frame 200 and the door bar 240, and the leg fixing belt 510 can be tied around the thigh to prevent the triangular frame lifting seat 500 from deviating due to shaking when sitting down. The door bar 240 is provided in a form that can be opened and closed on the frame 200, which is convenient for the user to enter and exit. When walking, the user holds the frame 200 and the door bar 240, and when suddenly losing strength or needing to rest, the leg fixing belt 510 tied around the thigh ensures that the user can accurately sit on the triangular frame lifting seat 500, and the user can sit on the triangular frame lifting seat 500 at any convenient time, so that the anti-falling walking aid vehicle not only effectively protects the elderly, the weak or the disabled from falling when walking or bathing, but also facilitates them to adopt a sitting position when using the toilet, thereby reducing the pressure on the legs. The left bottom rod 130 and the right bottom rod 150 are provided at both ends of the front bottom rod 140 to form the "Fang" shaped base frame 100, which facilitates the anti-falling walking aid vehicle to be pushed into a sitting toilet, so that the user can use the sitting toilet.

[0047] Further, the front bottom rod 140 extends outward at both ends to form a stabilizing rod 141, and the free end of the stabilizing rod 141 is provided with the caster 110. Figure 2 As shown in the figure, the stabilizing rod 141 is part of the front bottom rod 140, and the stabilizing rod 141 expands outward, and the caster 110 is installed at the free end of the stabilizing rod 141, so that the anti-falling walking aid vehicle is more stable and less likely to tip over; at the same time, when passing through a door, the stabilizing rods 141 at both ends can be twisted and inclined to pass through the door one after another, so that the width of the anti-falling walking aid vehicle can be increased as much as possible under the premise of ensuring smooth passage through the door.

[0048] Further, the lower part of the rear sling 430 is provided with a waist fixing belt 431. Figure 3As shown, the user binds the leg fixing belt 510 on the thigh and the waist fixing belt 431 on the waist, which can better place the triangular frame hanging seat 500 behind the hips, prevent the triangular frame hanging seat 500 from shaking and deviating, and enable the user to accurately sit on the triangular frame hanging seat; the waist fixing belt 431 can also be used to surround the left hanging belt 410 and the right hanging belt 420 from the outside and then be bound on the waist, which can better place the triangular frame hanging seat behind the hips and better prevent deviation.

[0049] Further, the reinforcing frame 310 is arranged in the middle of the support column 300, which is in the shape of a "Fang" character and surrounds the plurality of support columns 300 from the left side, the back side and the right side. As shown, Figure 1 The reinforcing frame 310 plays a role in increasing the structural strength of the whole vehicle, which surrounds the plurality of support columns 300 from the left side, the back side and the right side, and the front side is open for the user to enter and exit. The height of the reinforcing frame 310 can be higher than that of the sitting toilet, generally not less than 40 cm, so as to avoid the situation that the multifunctional anti-falling walking aid vehicle cannot be pushed into the sitting toilet due to the reinforcing frame 310 being too low.

[0050] Further,

[0051] The door post 240 is an arc-shaped rod, the left and right ends of the door post 240 are curved and extended, one end forms a door lock head 241, and the other end forms a door shaft head 242; the door lock head 241 is provided with a through inner pin hole 2411 in the radial direction thereof, the end of the door shaft head 242 is continuously extended to form a limiting neck 2421, the diameter of the limiting neck 2421 is smaller than that of the door shaft head 242, the free end of the limiting neck 2421 is enlarged to form a limiting head 2422, and an annular neck groove 2423 surrounding the limiting neck 2421 is formed between the door shaft head 242 and the limiting head 2422;

[0052] The front end of the left supporting rod 210 and the front end of the right supporting rod 220 are provided with a lock head sleeve 211 and a door shaft sleeve 221, respectively, the lock head sleeve 211 is provided with a through outer pin hole 2111 corresponding to the through inner pin hole 2411, and the door shaft sleeve 221 is provided with a limiting pin 2211.

[0053] The door shaft head 242, the limiting neck 2421 and the limiting head 2422 are pivotally inserted into the door shaft sleeve 221, and the limiting pin 2211 is inserted into the annular neck groove 2423; the door lock head 241 is inserted into the lock head sleeve 211, and the through inner pin hole 2411 and the through outer pin hole 2111 are opposite to each other, the door post 240 is fixed by inserting a locking pin 250 into the through outer pin hole 2111 and the through inner pin hole 2411, at this time, the clearance between the limiting pin 2211 and the limiting head 2422 is greater than or equal to the length of the door lock head 241.

[0054] As Figure 4 shown in FIG. 12, it is one setting mode of the door bar 240, which is convenient for users to enter and exit the anti-falling walker. The door shaft head 242 of the door bar 240 is inserted into the door shaft sleeve 221 of the right support rod 220 together with the limiting head 2422 and the limiting neck 2421. The limiting pin 2211 is inserted into the door shaft sleeve 221 opposite to the limiting neck 2422, so that the limiting pin 2211 extends into the annular neck groove 2423. When the door shaft head is pulled out, the limiting pin 2211 blocks the limiting head 2422, so that the front end of the door shaft head 242 is always limited in the door shaft sleeve 221, preventing the door bar 240 from falling off the door shaft sleeve 221. At the same time, the door shaft head 242, the limiting neck 2421 and the limiting head 2422 can rotate in the door shaft sleeve 221 to realize the opening and closing of the door bar 240. The door lock head 241 of the door bar 240 is inserted into the lock head sleeve 211, and the door bar 240 is locked by inserting the locking pin 250 through the outer pin hole 2111 and the inner pin hole 2411. At this time, the distance between the limiting pin 2211 and the limiting head 2422 is greater than or equal to the length of the door lock head 241. When the user wants to go out, pull out the locking pin 250 and push the door bar 240 forward. The door bar 240 moves forward relative to the support frame 200 until the door lock head 241 is out of the lock head sleeve 211. Then, the user can turn over the door bar 240 and get out of the anti-falling walker.

[0055] Further, the caster 110 is arranged on the base frame 100 through a load-dependent telescopic mechanism, which comprises:

[0056] A fixed sliding sleeve 610 is fixedly arranged on the base frame 100. An end sealing plate 614 is arranged at the top of the fixed sliding sleeve 610. A through rod through hole 611 is arranged at the center of the end sealing plate 614.

[0057] A sliding rod 620 is inserted into the through rod through hole 611. A tension nut 621 is threadedly connected to the upper end of the sliding rod 620. The radial dimension of the tension nut 621 is greater than the radial dimension of the through rod through hole 611. A limiting flange plate 622 is arranged at the lower part of the sliding rod 620. The lower end of the sliding rod 620 extends out of the lower end of the fixed sliding sleeve 610 and the caster 110 is arranged at the lower end of the sliding rod 620.

[0058] A telescopic spring 630 is sleeved on the sliding rod 620. The upper end of the telescopic spring 630 abuts against the inner side of the end sealing plate 614. The lower end of the telescopic spring 630 abuts against the limiting flange plate 622.

[0059] As Figure 5 , 6As shown, the load-bearing telescopic mechanism can reduce the jolt. The telescopic spring 630 is supported at both ends on the fixed sleeve 610 and the sliding rod 620. During the travel, the sliding rod 620 moves up and down in the fixed sleeve 610 and the through-hole 611 under the action of the telescopic spring 630, which can reduce the jolt. The radial dimension of the tension nut 621 is larger than the radial dimension of the through-hole 611, so the tension nut 621 cannot slide into the fixed sleeve 610 through the through-hole 611, thereby ensuring that the sliding rod 620 cannot be removed.

[0060] Further, the load-bearing telescopic mechanism further comprises a movable sleeve 640 arranged on the limiting flange plate 622. The movable sleeve 640 is inserted into the fixed sleeve 610 and covers the lower part of the sliding rod 620 and the telescopic spring 630. The movable sleeve 640 is in sliding fit with the fixed sleeve 610. The movable sleeve 640 can cover the lower part of the sliding rod 620 and the telescopic spring 630, thereby protecting them. In addition, the movable sleeve 640 occupies the gap between the fixed sleeve 610 and the sliding rod 620, thereby preventing the swinging of the sliding rod 620 during the travel.

[0061] Further, the load-bearing telescopic mechanism further comprises a resilient U-shaped clamp 650. The fixed sleeve 610 is provided with a pair of opposite hanging clamp through-holes 612 on the upper end side wall. The two ends of the resilient U-shaped clamp 650 are bent and extended towards each other and inserted into the pair of opposite hanging clamp through-holes 612 to clamp the fixed sleeve 610. When the buffer function of the load-bearing telescopic mechanism is not needed during the travel on the flat road, the resilient U-shaped clamp 650 can be turned upwards to the position where the U-shaped bottom of the resilient U-shaped clamp 650 faces upwards and surrounds the tension nut 621, thereby blocking the top end of the sliding rod 620, as shown in the figure, so as to limit the movement of the sliding rod 620 and the tension nut 621, so that the sliding rod 620 cannot move upwards. Figure 6

[0062] Further, the outer wall of the fixed sleeve 610 is provided with a retaining groove 613 along the axial direction. The retaining groove 613 extends upwards from the hanging clamp through-hole 612 to the upper end face of the fixed sleeve 610. As shown in the figure, when the resilient U-shaped clamp 650 is turned upwards to the vertical position, the two side clamping legs of the resilient U-shaped clamp 650 sink into the retaining groove 613 due to the inward clamping force of the resilient U-shaped clamp 650. Thus, the resilient U-shaped clamp 650 cannot be turned due to the vibration during the travel, and the sliding rod 620 and the tension nut 621 can be fixed more stably. Figure 5

[0063] ​​Further, the bottom frame 100 is provided with a stop column 120. The height of the stop column 120 is less than the height of the caster 110. During the moving process, the stop column 120 does not contact the ground. When it is necessary to rest or the user suddenly loses the ability to sit on the triangular frame 500, the weight of the user is applied to the multifunctional anti-falling walking aid vehicle, the telescopic spring 630 is compressed, and the stop column 120 contacts the ground. At this time, the multifunctional anti-falling walking aid vehicle can be quickly stabilized, the walking aid vehicle is prevented from freely moving without control, and dangerous situations are avoided.

[0064] Further, the caster 110 is a universal wheel. The caster 110 is a universal wheel, and the moving direction can be conveniently changed.

[0065] It should be understood that the parts not described in detail in the specification all belong to the prior art.

[0066] The above description of the preferred embodiments is relatively detailed and should not be considered as a limitation on the scope of patent protection of the present application. Those skilled in the art can make substitutions or modifications under the inspiration of the present application without departing from the scope of protection of the claims, and all fall within the scope of protection of the present application.
