Description

сажены конец рычага 10 и уголок с прорезью 14, закреплегашш на доске. Устройство работает следующим образом. При вращении гайки 2 влево, т. е. подачи руко тки 1 к себе, гайка отходит от втулки 9, втулка и фигурное звеио 8 ослабевают. При этом чертеж1гую доску можно установить в требуемое положение и закрепл ть поворотом руко тки 1 от себ . При этом гайки 2 вращаютс  вправо, нажимают на втулку 9, котора  передает давле ние фигурному звену 8 (втулка 9 свободно скользит по фиксирующему валу 3), а так как втул1ка 5 насажена на фиксирующий вал 3 наглухо, то фигурное звено 8 зажима.етс  между втулками 5 и 9. Дл  ограничени  угла наклона чертежной доски на втулке 9 приварен щтырь И, а на втулке 5 - штырь 7. Штыри 7 и 11 приварены так, что при максимальном угле наклона чертежной .доски штарь 11 упираетс  в неподвижный щтыр Использование изобретени  нозвол ет сократить врем  на установку чертежной доски, ее подъем и опускаию.The end of the lever 10 and the corner with the slot 14 are planted, fixed on the board. The device works as follows. When the nut 2 is rotated to the left, i.e. the feed of the handle 1 to itself, the nut moves away from the sleeve 9, the sleeve and the figure zoo 8 weaken. In this case, the drawing board can be installed in the required position and fixed by turning the handle 1 from itself. At the same time, the nuts 2 rotate to the right, press the sleeve 9, which transfers pressure to the figure link 8 (the sleeve 9 slides freely on the fixing shaft 3), and since the sleeve 5 is mounted on the fixing shaft 3 tightly, the figure link 8 of the clip. bushings 5 and 9. To limit the angle of inclination of the drawing board, sleeve I was welded on sleeve 9, and pin 7 was mounted on sleeve 5. Buttons 7 and 11 were welded so that, at maximum angle of inclination of the drawing board, the roller 11 rests on a fixed pin. do not reduce the installation time drawing th boards, its rise and fall.

фиг.1 Формула изобретени  1. Устройство дл  креплени  чертежной доси к столу, содержащее две прикрепл емые к толу стойки с установленным в них фиксирующим валом с руко ткой, на котором смонтированы два фигурных звена, св занных свободными концами с доской и предназначенных дл  изменени  угла наклона доски, и средство подъема и. опускани  доски, отличающеес  тем, что, с целью совмещени  операдай изменени  угла наклона доски с операцией подьема или опускани  ее, средство дл .п- дъема и опускани  доски выполнено в виде двух рычагов, свободно установленных на фиксирующем валу, и кинематически св занно со средством дл  изменени  угла наклона доски посредством рычагов и уголков с прорез ми, закрепленных на доске. Fig. 1. Claim 1. Device for attaching a drawing board to a table, comprising two racks attached to a floor with a fixing shaft installed in them with a handle, on which two figured links are attached, connected to the free ends with a board and intended to change the angle tilt board, and a means of lifting and. lowering the board, characterized in that, in order to combine operations to change the angle of the board with the operation of raising or lowering it, the means for raising and lowering the board are made in the form of two levers, freely mounted on the fixing shaft, and kinematically connected with the means for changing the angle of inclination of the board by means of levers and angles with slots attached to the board. 2. Устройство по п. 1, отличающеес  тем, что оно снабжено средствами дл  ограничени  угла наклона доски, выполненными, например , в виде двух щтырей, один из которых закреплен на рычаге, а другой - на стоике, на нути движени  штыр , закрепленного на рычаге.2. The device according to claim 1, characterized in that it is provided with means for limiting the angle of inclination of the board, made, for example, in the form of two plugs, one of which is fixed on the lever, and the other on the stoic, for the duration of the pin attached to the lever. /3/ 3 // /rVi/ rVi ЖF юYu Ф|фF | f SxSx иand -/3- / 3 уat
