Description

A kind of lowering or hoisting gear of bedside guardrail

Affiliated technical field

The utility model relates to a kind of lowering or hoisting gear of bedside guardrail.It is to prevent that the people on the bed from falling down bed, plays the security protection effect that the bedside guardrail mainly acts on.The bedside guardrail lifting device is used to go up and down the bedside guardrail, makes things convenient for people's turnover.The lowering or hoisting gear of this bedside guardrail can be applied to be installed on the bedside guardrail on the big bed, also can be applied on the guardrail of infanette or basket cot or sick bed.

Background technology

How safe ready ground elevating guardrail is a difficult point after installing guardrail.Patent 200610047830.5 discloses a kind of playpen that is installed on the big bed; Its shortcoming is: needs two hands to operate simultaneously, could accomplish the descending operation of guardrail, and just passable because must rise simultaneously or descend in the two ends of cross bar; If only can make two ends uneven with a hand; High on one side low on one side, make that easily producing friction between cross bar and the slideway makes a noise, even block; Even if also be not easy evenly moving on the cross bar both ends horizontal or descend with two hands sometimes, thereby produce noise or block.

The utility model content

The main purpose of the utility model is to simplify and convenient the rising and step-down operation as far as possible, reduces noise in the rise and fall, reduces rate of breakdown.Realize that singlehanded once-through operation just can rise or fall guardrail.

The technical scheme that the utility model adopted is: suppose that column has fixed, column described herein is vertical basically with bed surface, is meant that basically vertically the angle between column and the bed surface is spent greater than 70 degree and smaller or equal to 90.The bottom of enclosing is fixed; For example pass through sheer pole or lanyard at column lower end; Here instigate it not move up enclosing bottom, or can move within the specific limits, but just can not continue to move up after arriving certain altitude.Enclosing is by soft braid or yarn fabric or can process by vertically folded material, and for example common Bamboo summer sleeping mat or straw plaited summer sleeping mat is exactly a kind of material that can be vertically folded in the life, and as preferably, enclosing can adopt eyelet fabric.The top of enclosing links to each other with cross tube, and cross tube links to each other with column through whirligig, drives enclosing when cross tube rotates to low level through whirligig and falls, and drives enclosing when cross tube rotates to a high position through whirligig and rises.

Whirligig comprises swingle and rotating shaft, and swingle links to each other with column through rotating shaft, and rotating shaft is parallel with cross tube, and cross tube can rotate around rotating shaft through swingle.The position of rotating shaft is higher than the following place of guardrail level height; The following place of said guardrail level height generally is meant bottom's place level height of enclosing; Exception is also arranged, for example, if connection enclosing bottom is sheer pole; The thick 2cm of sheer pole, the following place of guardrail level height just is meant that bottom's place level height of enclosing moves down 2cm more so.The position of rotating shaft is higher than the following place of guardrail level height; The benefit of design is to be above the ground level after cross tube is fallen like this, avoids cross tube to fall and hinders the bedside station people afterwards, because the general height of bed 30 is to 40cm; If the height of guardrail reaches 40-60cm; If rotating shaft is the same with bed surface high or be lower than bed surface place horizontal level, cross tube can land after descending so, and can hinder bedside to sit people or people from station; As preferably, rotating shaft is less than or equal to the mid point place level height between cross tube and the bed surface, can guarantee that like this cross tube is fallen after, cross tube is lower than bed surface place level height, if cross tube is higher than bed surface, will hinder bedside to sit the people so.Cross tube links to each other through rotating shaft with swingle, perhaps fixed linking to each other, perhaps constitutes swingle by the bending of cross tube elongated portion.Can adopt automatically in the process of rise guardrail or manual catch means locking whirligig or cross tube, prevent that cross tube is rotated down.Catch means can be arranged on cross tube or whirligig or the column, perhaps be arranged in the middle of the above-mentioned three wherein on two or three, for example catch means is arranged on the rotating shaft automatically, the office of unblanking is arranged on the cross tube.

Can have certain gap between the side of enclosing and column or the swingle, tight inadequately if the side elasticity of enclosing is big or enclosing stretches tight, so baby might be from this space stretched head or arm, have potential safety hazard.Following four kinds of solutions are arranged: 1. the enclosing side adopts the rope that does not have retractility to make; Among this paper; Do not have the rope of retractility to be meant with 1 meter long rope and sling after 20 kilograms the object, its length is less than 1.05 meters, for example thicker nylon rope band or iron chains; 2. adopt one not have the rope of retractility to link to each other with the enclosing side, rope upper end and swingle or rotation pole or cross tube link to each other, as preferably; The upper end of rope links to each other with swingle or rotation pole maybe be more better; Because: rope was tightened after cross tube rose, if the rope upper end links to each other with cross tube, will give downward pulling force of cross tube so; If catch means is arranged on the cross tube; And need to rotate cross tube and control catch means, rope increases resistance will for the rotation of cross tube for the pulling force of cross tube, if the rope upper end links to each other with swingle or rotation pole then can not produce this defective; 3. the enclosing side is linked to each other with column through carriage, the side that for example adopts marline to pass enclosing is lower than the part of rotating shaft, is enclosed within then on the parallel continuous slide bar with column; 4. the enclosing side links to each other through carriage with swingle.Above-mentioned four kinds of solutions can be implemented separately also can make up enforcement, and for example scheme one is implemented with scheme four combinations.

In order to let the cross tube bed body of fitting more after falling, also can swingle be designed to crooked.
