Walking aid for old people

Technical Field

The invention belongs to the technical field of auxiliary appliances, and particularly relates to a walking aid for the old.

Background

The walking aid can be supported by the aid of the walking aid, so that the old and the patients with inconvenient legs and feet can take care of the disabled legs and feet and even the people without walking ability. For example, the walking aid disclosed in chinese patent CN108338897A can support walking, but the roller on the walking aid cannot be detached and adjusted to the use state of the object roller, so that the application situation and the population are limited.

Disclosure of Invention

The invention provides a walking assistant for old people with detachable rollers, aiming at overcoming the defects of the prior art.

In order to achieve the purpose, the invention adopts the following technical scheme: an old man is with helping capable ware of riding instead of walk, include

The frame body comprises a left frame body and a right frame body, and the left frame body and the right frame body are connected through a cross rod;

the toppling protection device is used for protecting the legs of a user when the rack body topples; the air bag part is provided with a folding state and an unfolding state, and the air bag part is in the folding state in the initial state; when the frame body falls, the support rod pushes against the ground to move upwards, and the air bag piece is driven to be converted into a unfolding state by the driving device;

the roller assembly is detachably connected with the frame body and can drive the frame body to move through the rollers;

the dismounting structure is used for realizing the dismounting connection between the frame body and the roller component.

When the frame body is toppled, the air bag pieces are unfolded, so that the air bag pieces are arranged at the positions corresponding to the affected limbs, and when a patient topples to the ground along with the frame body, the positions of knees, crus and ankles are basically contacted with the air bag pieces, so that the condition that the affected limbs are directly contacted with the ground is effectively avoided, and the affected limbs are prevented from being secondarily injured; the frame body is detachably connected with the roller, so that the frame body can be driven by the roller to move, and the walking is more labor-saving; the detachable connection can freely adjust whether the roller is arranged, when the walking aid is used by old people with poor control force or small leg strength, the roller assembly can be detached, so that the phenomenon that the moving speed of the walking aid is too high or enough supporting force cannot be improved for the old people is avoided;

secondly, the air bag part has a folding state, part of the air bag part is coated on the lower part of the frame body in the folding state, and when the air bag part is popped out, one end of the air bag part coated on the outer side of the frame body is unfolded, so that the supporting foot at the lower part of the frame body is shielded by the air bag part in the unfolding state, the wounded limb is prevented from being hit on the supporting foot, and the wounded limb is further prevented from being secondarily injured; the air bag piece is in a folding state when not used, so that the space occupation of the air bag piece when the frame body is normally used is reduced, the whole volume of the frame body is ensured not to be changed excessively, and the use feeling is light; support the pole and offset can pass through drive arrangement drive airbag spare and expand with ground, and reaction rate is fast, and airbag spare expandes rapidly, when guaranteeing that the patient emptys, and airbag spare homoenergetic normally expandes, improves the protection effect.

Preferably, the roller assembly comprises a connecting rod, a U-shaped joint arranged at the lower part of the connecting rod and a roller which is rotatably connected with the U-shaped joint through a shaft pin; the connecting rod is arranged in a hollow manner, the left frame body and the right frame body are respectively provided with a front supporting leg and a rear supporting leg, the front supporting leg is screwed with a grounding rod, and a rubber pad is arranged at the lower part of the grounding rod; the disassembly and assembly operation is simple and convenient.

Preferably, the dismounting structure comprises a telescopic head arranged on the front supporting leg and a positioning hole arranged on the side wall of the connecting rod and matched with the telescopic head; under this kind of structure, only need control flexible head locating hole department outwards to wear out, can realize the firm connection of connecting rod and spike, easy dismounting, assembly easy operation.

Preferably, the connecting rod is provided with a threaded sleeve, and the front supporting foot is provided with an external thread in threaded fit with the threaded sleeve; through the connection of swivel nut, further realize the location to wheel components, firm in connection.

Preferably, the lower part of the threaded sleeve is provided with an annular bulge with a T-shaped cross section, the upper part of the connecting rod is provided with an annular groove for the annular bulge to penetrate, and the shape of the annular groove is matched with that of the annular bulge; with the structure, the thread insert can be effectively prevented from being separated from the connecting rod, and the thread insert can be ensured to rotate relative to the connecting rod.

Furthermore, the driving device comprises a box body fixedly connected to the frame body through a connecting rod, a first driving part and a second driving part which are arranged in the box body, a first connecting piece connected with one end of the air bag piece, a second connecting piece connected with the other end of the air bag piece, a hook piece arranged on the first connecting piece and a locking piece matched with the hook piece; in the process that the abutting rod moves upwards, the first driving part drives the locking piece and the hook piece to be released from matching, and then the second driving part drives the second connecting piece to move along the length direction of the air bag; under the structure, the part needing to be popped out and unfolded can be arranged to be shorter, so that when the frame body topples, the air bag piece cannot be popped up due to the fact that the distance between the frame body and the ground is too small; meanwhile, after the air bag member is bounced open, the air bag member can move outwards for a certain distance, and the condition that the affected limb cannot be well protected due to the fact that the unfolded part is too short is avoided; and the unfolded part is positioned in a locking mode of matching the hook part and the locking part, when the positioning is released, the air bag part can be popped out, and the air bag part is unfolded rapidly.

Furthermore, the abutting rod comprises a driving section penetrating into the box body and an abutting section positioned outside the box body, a driving rack matched with the first driving part is arranged at the upper part of one side of the driving section, and a rack matched with the second driving part is arranged at the lower part of the other side of the driving section; under the structure, when the support rod is abutted against the ground and pushed upwards in the toppling process of the frame body, the driving rack on the upper part of one side of the driving section drives the first driving part to start firstly, so that the locked end of the air bag part is popped outwards, and then the rack on the lower part of the other side of the driving section is started with the second driving part to make the air bag part move outwards; thereby realize that the gasbag spare is flicked and is gone on for the front and back with the removal operation, effectively avoid flicking and remove to go on simultaneously or move when being earlier than flick operation, the gasbag spare part that needs to expand can not increase, can not take place the friction or contradict with ground when guaranteeing that the gasbag spare is flicked.

In summary, the invention has the following advantages: the frame body is detachably connected with the roller, so that the frame body can be driven by the roller to move, and the walking is more labor-saving; and the detachable connection can freely adjust whether to set up the gyro wheel, when supplying the relatively poor or less old man of shank strength of control power to use, can pull down the roller subassembly, avoids the removal speed of helping the capable ware too fast or can't improve sufficient holding power for the old man.
