Abstract
Abstract A linear positioning device such as for optical measurements, having a base plate, an object carrier and a micrometer screw. Protruding extensions are formed on the base plate, a compensating member is arranged between the base plate and the object carrier. An actuating lever is inserted between the support of the object carrier and the operating micrometer screw. The compensating member is connected by leaf springs both to the extensions of the base plate and to the support of the object carrier, while said support is connected by a spiral spring to the extension of the base plate. The actuating lever of the device is connected by means of a transverse-spring-actuated joint to the extension of the base plate and by a leaf spring to the support of the object carrier and the operating micrometer screw which is led through one of the extensions of the base plate, is bearing up against the actuating lever.

Claim 1
Independent Claim
191 words
A linear positioning device, preferably to optical measurements, incorporating a base plate, an object carrier and a micrometer-screw, characterized in that on the base plate (21) protruding extensions (35, 36, 37, 38, 39) are formed, furthermore between the base plate (21) and the object carrier (24) there is a compensating member (23) and between the support (25) of the object carrier (24), the object carrier (24) itself and the micrometer-screw (29) there is an actuating lever (28), whereby the compensating member (23) is connected to the extensions (35, 36) of the base plate (21) by means of leaf-springs (22) and simultaneously it is connected by leaf-springs (26) to the support (25), while said support is connected by a spiral spring (34) to the extension (39) of the base plate (21), furthermore the actuating lever (28) of the device is connected by means of a transverse-spring-loaded joint (27) to the extension (37) of the base plate (21) and by the leaf-spring to the support of the object carrier and at last the micrometer-screw (29)--led through one of the extension (36) of the base plate (21)--is bearing up against the actuating lever (28).

A linear positioning device, preferably to optical measurements, incorporating a base plate, an object carrier and a micrometer-screw, characterized in that on the base plate (21) protruding extensions (35, 36, 37, 38, 39) are formed, furthermore between the base plate (21) and the object carrier (24) there is a compensating member (23) and between the support (25) of the object carrier (24), the object carrier (24) itself and the micrometer-screw (29) there is an actuating lever (28), whereby the compensating member (23) is connected to the extensions (35, 36) of the base plate (21) by means of leaf-springs (22) and simultaneously it is connected by leaf-springs (26) to the support (25), while said support is connected by a spiral spring (34) to the extension (39) of the base plate (21), furthermore the actuating lever (28) of the device is connected by means of a transverse-spring-loaded joint (27) to the extension (37) of the base plate (21) and by the leaf-spring to the support of the object carrier and at last the micrometer-screw (29)--led through one of the extension (36) of the base plate (21)--is bearing up against the actuating lever (28).
Claim 3
Dependent Claim
102 words
Positioning device as claimed in claim 1, characterized in that the device is provided with a second frame-shaped actuating lever (32), whereby the first actuating lever (28)--against which the micrometer-screw is bearing upon--is enclosing the compensating member (23) and the support (25) of the object carrier only and it is connected by means of a transverse spring-loaded joint (31) to one of the extensions (38) of the base plate (21) and by a leaf-spring-loaded push rod (30) to the first actuating lever (28), simultaneously it is connected to the support (25) of the object carrier (24) by means of a leaf-spring (33).
