Description

II

Изобретение относитс  к мед.ицнне, в частности к протезированию и протезостроевию ..The invention relates to medical, in particular, to prosthetics and prosthetics.

Известна искусственна  кисть, содержаща  корпус, внутри которого-установлены св занные посредством осе пальцы, зубчатый сектор, сателпит, рычаги , пальцевую т гу и пружину, один конец которой соединен с сателлитом, а другой - с корпусом М . Однако известна  кисть не обеспечивает сипы захвата, пропорциональной весу пред- метов, и регулировани  ее.An artificial brush is known, comprising a housing within which axle-mounted fingers are mounted, a toothed sector, satellite, levers, a finger pull and a spring, one end of which is connected to the satellite and the other to the housing M. However, the known brush does not provide a gripping point, proportional to the weight of the objects, and its adjustment.

Целью изобретени   вл етс  получение самозахвата предметов с силой, пропорциональной нх весу, и регулирование силы захвата. В предлагаемой кисти это достигаетс  тем, что внут-. ри ее корпуса установлены направл к ший ролик, расположенный на одной из осей, и дополнительна  т га, соединенна  с сателлитом, направленна  противоположно пальцевой т ге и взаимодействующа  с роликом.The aim of the invention is to obtain self-gripping objects with a force proportional to their weight and control the gripping force. In the proposed brush, this is achieved by the fact that int. A cushioned roller, located on one of the axes, and an additional cable, connected to the satellite, directed oppositely to the finger line and interacting with the roller, are installed in its casing.

На. чертеже показана предлагаема  искусственна  кисть, вид спереди.On. The drawing shows the proposed artificial brush, front view.

Она содержит корпус 1, первый палец 2 и блок 3 второго- п того пальцев , с0единен 1ых с корпусом ос ми 4 и 5,. Первый палец щарнирно соединен пocp6дcтвo эвена 6 с блоком второго - п того пальцев и посредством звена 7 с водипом 8, соединенным с корпусом осью 9 и имеющим упор 10 дл  сателлита 11, расположенного на оси 12, который может входить в зацепление с зубчатым сектором 13, неподвижно укрепленным на корпусе 1. На. птеллите укреплены пальцевые т ги 14 и 15 ипружина 16. Внутри корпуса расположен направл ющий .ролик 17, установленный на оси 18, посредством которой с корпусом соединена, также пружина 16. Трубка 19 предплечь  прикреплена к корпусу 1. На кисть надета эластична  оболочка 20.It contains the body 1, the first finger 2 and the block 3 of the second and fifth fingers, connected one with the body axes 4 and 5 ,. The first finger is pivotally connected by the connection of the Even 6 with the block of the second to the fifth fingers and through link 7 with the water supply 8, the axis 9 connected to the body and having a stop 10 for the satellite 11 located on the axis 12, which can engage with the gear sector 13, fixed on the body 1. On. The ptellite has finger braces 14 and 15 and a spring 16. Inside the case there is a guide roller 17 mounted on the axis 18, through which the spring 16 is also connected to the case. The tube 19 of the forearm is attached to the case 1. The elastic shell 20 is attached to the brush.

При выборке т ги 14 сателлит 11 поворачиваетс  на .оси 12 до упора 10 водила 8, .т.е. до положени , соответWhen hauling 14, the satellite 11 rotates on axle 12 until it stops 10 drove 8, i.e. to position
