Description
Technical Field
The utility model belongs to the technical field of help the capable ware, especially, relate to a help capable ware with supplementary parking function.
Background
The structure of a common four-wheel walking aid is shown in utility model patent publication No. CN2496446Y, which comprises a hand brake, a cushion, a brake action point, a rear wheel, a front universal wheel and the like. At ordinary times, the old can push the walking aid to assist walking, the hand brake can be pressed down when emergency needs braking, and force is transmitted to a braking action point to brake a rear wheel. When a user needs to sit down for rest, the hand brake needs to be pulled downwards, so that the rear wheel is in a braking state for a long time, the stability of the walking aid is ensured when the user sits down, and the user is prevented from falling down.
The four-wheel walking aid needs the old to manually lock the wheels to prevent the wheels from sliding, the group memory of the old is generally poor, the old forgets to pull down the hand brake easily when the old wants to sit down for rest, the wheels are still in a running state, and the old can fall down after sitting up and the walking aid slides backwards easily, so that the consequence is unreasonable.
Other forms of braking for four-wheeled walkers are also disclosed in the prior art.
The utility model discloses a patent of utility model publication No. CN202724206U discloses a walking aid, including frame, walking wheel, support handle and manual brake mechanism, the frame includes bracing piece and a pair of back bracing piece before a pair of, and the middle part of bracing piece links firmly mutually through preceding horizontal pole before two, and the middle part of two back bracing pieces links firmly mutually through the back horizontal pole, is equipped with bedplate, its characterized in that on horizontal pole and the back horizontal pole in the front: the lower end part of the front supporting rod or the lower end part of the rear supporting rod is provided with a self-weight brake mechanism, the bottom of the front supporting rod or the rear supporting rod forms a foot part, the self-weight brake mechanism drives the foot part to be lifted upwards and lifted off the ground when the walking aid is in an idle state, and the self-weight brake mechanism drives the foot part to be grounded to form automatic brake when the walking aid is in a manned state. Compared with the prior art, the utility model has the advantages of: the whole structure of the walking aid is simple, the self weight of the human body is utilized to brake, and the safety and the reliability of the braking of the walking aid in a manned state can be ensured.
The utility model with the publication number of CN201798883U discloses a walking aid with safety brake performance, which comprises a wheelchair, wherein the wheelchair is composed of a chair frame and a walking wheel mechanism connected with the supporting leg of the chair frame, a lifting spring is arranged between the supporting leg and the roller shaft in the walking wheel mechanism in the longitudinal direction, one end of the lifting spring acts on the supporting leg, the other end acts on the roller shaft, so that the supporting leg and the roller shaft form elastic connection, and the roller shaft is connected with a roller; the supporting legs extend to the ground direction to be provided with feet for braking, when the wheelchair is in an idle load state, the rollers contact the ground, the lifting springs lift the feet through the supporting legs, the feet are suspended relative to the ground, and when the wheelchair is in a full load state, the feet are grounded to form a dead weight braking mechanism. When walking is practised, the spring lifts the wheelchair frame, the feet are suspended on the ground, and when the wheelchair is used for rest, the feet are grounded by the dead weight of the human body to form automatic braking. The scheme overcomes the defects of the brake design of the conventional similar walking aid, and ensures the safety of the brake of the walking aid to the maximum extent.
For example, the invention patent with publication number CN102247262B discloses an automatic brake device for a walking aid in the technical field of walking aids, which comprises: the device comprises an infrared sensor circuit, a triode switch circuit, a power supply and two electromagnetic brakes. The utility model discloses an infrared sensor can perceive the distance that helps capable ware user and help capable ware, when this distance is within the certain limit, this is normal supplementary walking, and brake equipment does not trigger. When the distance exceeds a certain range, the condition of abnormal use is judged, the user is not near the walking aid at present, the automatic brake device is immediately triggered, and the walking aid is braked and locked, so that the accident is prevented.
Above-mentioned notice number CN202724206U and CN201798883U technical scheme adopt dead weight brake, and notice number CN 102247262B's technical scheme adopts infrared induction brake, and it can improve certain security and reliability than the manual brake, nevertheless still can have the defect of slipping when using: if the dead weight brake is in a non-braking state when a user does not sit, the user may slide the walking aid in the sitting process, and the dead weight parameter of the dead weight brake is difficult to determine; if the infrared induction brake is easily triggered by sundries by mistake, the distance between a user of the walking aid and the walking aid cannot be effectively sensed, and the normal use condition or the abnormal use condition cannot be accurately judged.
