Description

残疾人轮椅
本发明涉及残疾人轮椅，用以使下肢失去行动能力的残疾人能够移行。
已知的轮椅具有装在构架上的折叠式带衬垫的靠背、扶手、座部、带叉的主动轮和前轮以及踏板(GB 1339992，C1.B62D 57/02，1973)。
现有轮椅的缺点是结构复杂，构架过重和使用不方便。
本发明的目的是使残疾人轮椅结构简单和使用方便。
本发明的实质是：轮椅具有连接横杆、连杆、与构架连接的套筒、装在套筒内带有弹簧按钮的轴套，按钮在其内表面上具有凹槽，构架由两个彼此通过横撑作横向连接的构体构成，因而可对座部的宽度进行调节，靠背具有两个彼此作横向分开设置的支杆，支杆通过横撑彼此连接而在构架各构体的上表面上作铰接安装，衬垫3在座部一侧装在支杆上，连杆在构架各构体的上表面上作铰接安装，构架各构体的连杆和支杆与扶手作平行四边形的铰接式连接，叉轴通过定位器与轴套连接，定位器具有转体，转体装在叉轴上的环形沟槽和轴套上的孔内，弹簧按钮可移动而盖在带转体的孔上并使转体落进槽内。
轮椅最好具有护板，护板装在构架的构体上和靠背的支杆上，护板是用挠性材料制成的。
套筒最好与构架通过卡箍连接。
扶手、横撑、连杆、构架构体和支杆应用轻合金、塑料或复合材料制成。
采用本发明可使结构简单，使用方便。
现对本发明的具体实施例按附图说明如下，图中：
图1为本发明残疾人轮椅的全视图，
图2为本发明沿A-A线的剖面图，
图3为本发明沿Б-Б线的剖面图，
图4为本发明沿B-B线的剖面图，
图5为本发明沿Г-Г线的剖面图，
图6为本发明沿Д-Д线的剖面图，
图7为本发明沿E-E线的剖面图。
残疾人轮椅具有装在构架1上的折叠式带衬垫3的靠背2、扶手4、坐位5、带叉8的主动轮6和前轮7以及踏板9(图1)。
轮椅具有连接横撑10、连杆11、与构架1连接的套筒12、装在套筒内带有弹簧按钮14的轴套13，按钮在其内表面上具有凹槽15(图1、2)。
构架1由两个彼此通过横撑10作横向连接的构体16构成，因而可对坐位5的宽度进行调节，靠背2具有两个彼此横向分开设置的支杆17，支杆通过横撑10彼此连接而在构架1各构体16的上表面上作铰接安装。
衬垫3在坐位5一侧装在支杆17上，连杆11在构架1各构体16的上表面上作铰接安装。
构架1各构体16的连杆11和支杆17与扶手中作平行四边形的铰接式连接(图1)。
叉8的轴18通过定位器与轴套13连接，定位器具有转体19，转体装在叉8轴18上的环形沟槽20和轴套13上的孔内。弹簧按钮14可移动盖在带转体19的孔上并使转体落进凹槽15内(图2)。
轮椅具有护板21，护板装在构架1的构体16上和靠背2的支杆17上，护板是用挠性材料制成的。
套筒12与构架1通过卡箍22连接(图2)。
扶手4、横撑10、连杆11、构架1的构体16和支杆17应用轻合金、塑料或复合材料制成。
轮椅具有弹簧23、轴承24和用于卡箍22的环形沟槽25(图2)。
轮椅还具有铰接接头26、27、垫板28、螺钉29、螺帽30、螺钉31、螺帽32和座部衬垫33(图3-7)。
构架1的各构体16具有相同的形状和尺寸并具有等强度薄壁开口形断面。
用轻合金、塑料或复合材料通过铸造或模压制造构件可减少劳动工时，取得重量轻、刚性好、成本低的结构。
可采用长度不同的横撑10而改变轮椅的尺寸从而将其用作孩童型和成人型轮椅。
采用由挠性材料制造的护板21和折叠式靠背2以及采用可快卸的主动轮6和前轮7可在运输时快速而方便地将轮椅折叠到最小的外形尺寸。
本发明的残疾人轮椅的使用方法如下：
为卸下带叉8的前轮7，按下按钮14，凹槽15就进入面对转体19(滚珠)的状态。
按住按钮14而将叉8向下拉，沟槽20的边沿就将转体19压进凹槽15，叉8的轴18也就松脱，这就可将其从轴套13中取出。再松开按钮14。
为重新将前轮7装上构架1，按下按钮14，将叉8的轴18插入轴套13，使轴顶靠在轴套的顶端。松开按钮14，凹槽15的边沿就将转体19从轴套13压进沟槽20。按钮14进一步移动而关住转体19，从而防止转体在偶然向外拉出轴18时从沟槽20中脱出。
轮椅是用手转动主动轮6使其移动的。
这样，本发明使轮椅的结构简单，使用方便。
本发明可用于残疾人轮椅的制造。
