Description

The method that the shape arm that crawled with level prevents Falls Among Old People

Technical field

It is specifically a kind of to prevent the side of Falls Among Old People with level snake shape arm the present invention relates to nursing device field Method.

Background technology

It is well known that China man at an advanced age is more and more, and the nursing staff for looking after old man is too busy to do it, many houses Support parents or live at a home for the aged the old man of rehabilitation officer, and more especially have dizzy disease easily falls the elderly, because they often can be unexpected Between have a dizzy spell and fall down to the ground with regard to producing, even with crutch, anti-fall that frame, wall side handrail etc. are existing anti-to fall protector all without Ji In thing.Once designing four pin of band of an old man in person has the vertical circle of roller, child's go-kart is somewhat like, due to being the big person Body is high, crank, and following four caster must be opened to open very much, and people can not pass in and out toilet door with it, and old man, which carries, sets about acid, puts Poor, easily rollover of determining power after the obstacle of the ground such as door is bumped against to ground upper roller, once do not have any to hold on rollover, side Its power, thus it is extremely dangerous；In order to solve the problem that old man's dizziness is easily fallen in family, someone also designs one and anchors at landing Pulley track on thing (Ru Fangqiang), by pulley of the bolt on the safety belt rope connecting orbit with old man, though old man can be with Pulley is advanced, but old man's travel track can only be according to track, it is impossible to which tortuous, change, running into needs the door of open and close, can not just fill Fixed track；More difficultly due to safety belt pull-up it is very heavy human body, once tumble track is difficult to bear human body Gravity, even with the electronic walker that can be started at present in outdoor, its gravity also can not live the human body of tumble surely.Therefore it is general Other have to ask nurse to support by the arm all day long at high price and hold the old folk by the arm, because this work very diligently, and must will have certain physical efficiency, institute Even if watching the easy nurse for falling old man with clothes to outbid all to be difficult to call.But easily fall old man due to this and do not go into the street typically, be in Scope of activities is also little, mainly bedroom, lavatory, these three places of dining table, such as takes the centre position of three, then its radius of action 3 meters will be no more than.Old friends look forward to having inventor can using senior activity's scope it is small hold different property, invention one kind, which can be attended by, easily falls Old man closely walks about indoors or in ward, toilet, and have a meal all can not fall safeties from the anti-of body, to easily fall old man and its Children bring convenience and trusted！It will also make family save many nurse fees to use, such as will also mitigate medical matters people in clinical application The generation of accident and conflict between doctors and patients is got injured by a fall in the stress of member and reduction in institute old man.

The content of the invention

The purpose of the present invention is：Proposition is a kind of without electric power, can attend by old man's movement track in house small range expert Walk it is anti-fall device, when old man falls accidentally, this is anti-, which to fall device, support, cushioning effect, so as to reduce the side that old man gets injured by a fall risk Method.

The object of the present invention is achieved like this：It includes anti-falls and enclosed and a level snake shape being made up of chain Arm, the anti-circle that falls is connected to above the strut on ground, and its plane is tilted to strut；Terminated under strut on support rod, strut End is inserted in deep groove ball bearing inner sleeve admittedly, and deep groove ball bearing outer ring is seated in the axle room that chain end is connected with afterbody carrier bar； Each chain link of composition level snake shape arm chain is made up of outer plate, inner plate and the middle miniature bearing for being inserted with chain pin, chain Pin and ground are vertical, and inner plate and miniature bearing outer ring are fixedly connected with, and outer plate and the chain pin being seated in miniature bearing are affixed, interior Carrier bar and outer plate are rotated by miniature bearing ball mutually precision, lubrication；Chain link amount used in whole chain, so that snake shape chain Bar can swim into toilet door minimum dosage number be set point value；The stem carrier bar end and ground of level snake shape arm chain are vertical Face on be also provided with the cross-drilled hole axle for being installed with and mutually being slided with it in cross-drilled hole, cross-drilled hole, cross-drilled hole axle is inserted in admittedly to be held on axillare, is held under axillare Face and be under stem carrier bar support spring plank it is affixed, hold axillare medial surface and rotation set be affixed, be installed with the middle of rotation set with its mutually slide It is that set is supported in regulation of the rotation jail on load axle below dynamic load axle, rotation set, load axle is connected in landing thing by installation component On；Supporting set by turn regulation makes the level height of snake shape chain be in more than the crown of people, but the slightly below height on doorframe top Degree；It is characterized in that：The stem carrier bar of the snake shape arm and stage clip is provided between spring plank, usually pressure spring force made by chain and The connected support rod of strut leaves ground；And when manpower or human bady gravitational press to stage clip, support rod can reach ground, to support The power of pressure.

So, because chain is can arbitrarily to bend in the horizontal plane, therefore it can swim into or swim out of lavatory etc. as snake The length of each carrier bar is approximately the 1/3 of doorframe width above cubicle, chain, typically at 30 centimeters or so, in a word with chain energy Swim lavatory, because chain periphery garden slide, therefore when entering and doorframe friction it is minimum；Chain pin per chain link will have certain height Degree is to increase torsional moment, and stem carrier bar highest (about 2 centimeters), height is higher, and it is smaller with the ratio between the moment of chain length, and due to Chain link used seldom, and selects the small miniature bearing of end-play, and this is it is ensured that whole piece chain substantially remains in horizontal direction fortune It is dynamic, and support rod supports set by the regulation under rotation set, makes the appropriate location that its ground clearance is no more than 10 centimeters；Due to this patent Chain used is not required to match with sprocket wheel, therefore the height and load intensity of the chain pin diameter of chain link and carrier bar can all be passed from front to back Subtract, and can relatively freely use lightweight or hollow material and reinforcing rib structure, therefore the weight of whole chain can be reduced To the 1/2 of conventional chain, control outer plate length is 30 millimeters of conventional chain, and its every meter weight is 0.91 kilogram, is now three The long special chain of rice, its weight is when being no more than 1 kilogram half, in translation activity, mainly overcomes 10 miniature bearing frictions Power (because 3 meters long, altogether about 10 carrier bars), therefore easily can promote chain link human body is on completely.Strut, support rod Made with the anti-circle that falls of book wall stainless steel, thus it is also very light (the anti-circle that falls always weighs about 2 kilograms), so level snake shape arm The required power of carrying is compared the power that human body lifts with safety belt rope with noted earlier, small several ten times, and this just makes level snake shape Arm becomes light and handy and feasible, and because it is arranged on the space higher than the number of people, anti-to fall circle the used time be together with strut one Rise and easily unloaded from afterbody carrier bar, it is the chain that a level folding is put to stay in space, and such as it can be as public in hospital Facility.Anti- circle side of falling is lock ring, and lock ring one end is active pin, and the other end can be steady pin.Usually during old man's standing action, At this moment support rod is not in contact with the ground under due to being acted in stage clip, and human body unconsciously can just promote the anti-circle that falls in walking, and The speed of old man's action is slower, and the anti-circle that falls is again light, therefore will not produce big impulse force.Due to chain, usually horizontal be in is higher than The number of people, but the slightly below position on doorframe top, so chain is not blocked for the action of ordinary people, and when old man need to be gone between lavatory When, because the level of chain snake sample is moved about, it is possible to make one to enter in lavatory easily, strut can also make use in shaft pertaining Lower 360 degree freely rotate, and body can be conveniently adjusted various activities orientation by people, such as held object walking, sat Just or strut crutch walking etc. is made.When people falls, stage clip is compressed under human bady gravitational, and the anti-circle that falls is compressed to support rod Contact to earth and by Gravity support, because the anti-circle that falls is tilted to strut direction, when old friend's body is fallen, gravity slides to strut direction, all Gravity falls substantially to be had in the support rod of anti-skid rubber cushion in bottom corner, therefore level snake shape arm need to only overcome anti-fall to enclose what is produced Turn on one's side power, as long as the carrier bar of chain has certain width and chain pin there are enough mechanical strengths, it is possible to rollover is carried out effective Control, or rollover speed is buffered significantly, so as to be protected to old man；Due to this control and cushioning effect, therefore support The span of bar touchdown point be not required to it is too big, and touchdown point leave the sufficient operating range of people can also farther out, this is with regard to that can make one the various of pin Lavatory is not entered in action because being hindered with the presence of support rod, such as will not can not also enter because door is narrow.Load axle can be made a variety of solid Setting formula, in addition to being fixed in embodiment on wall, can also use and be used as bearing column with push rod between ground and roof Form and the form for fixing its bearing column on the ground, such as some homes for destitute can insert bearing column admittedly on outdoor meadow, Each personal various forms of struts can also be attached to level snake shape when dizzy old man expects outdoor small range activity to hang In the axle room of arm afterbody carrier bar.
