便携式画架，可多角度调节。
专利摘要
改进的便携式画架(10)包括两个功能部分：底座(12)和臂架(16)，通过由可调离合器(14A, 14B)形成的锁定铰链机构(14)固定在一起。臂架包括多个具有肘形弯曲(52A, 52B)的构件，在连接到铰链机构(14)的远端包含多个开口，在近端包含多个开口，使得近端开口成直角。该铰链机构允许弯曲的支架向下折叠在底座和支腿上以便紧凑存放，并向上折叠以形成一系列角度。可调长度的臂(22)通过可调离合器(18)连接到臂架，允许臂在平面内自由枢转直至锁定在适当位置。可调支撑腿(20)枢转地固定在底座中的倾斜切口(42)内。滑动、可调的艺术品支架(24)通过可调夹具连接到臂上。
Original abstractImproved portable easel ( 10 ) comprising two functional sections, base ( 12 ) and arm holder ( 16 ) fastened together with locking hinge mechanism ( 14 ) formed by adjustable clutches ( 14 A, 14 B). The arm holder comprises a plurality of members with an elbow-shaped bend ( 52 A, 52 B), containing a plurality of openings in the distal end attached to the hinge mechanism ( 14 ) and a plurality of openings in the proximal end, such that proximal openings are at right angles. This hinge mechanism permits the curved holder to fold down over the base and the legs for compact storage and up for a range of angles. Adjustable length arms ( 22 ) are attached to arm holder with adjustable clutches ( 18 ), allowing arms to freely pivot in a plane until locked in position. Adjustable support legs ( 20 ) are pivotally fastened within angled cutouts ( 42 ) in the base. Sliding, adjustable, artwork holders ( 24 ) are attached to the arms with adjustable clamps.
