Claims
- 1. In a securing device composed of a plurality of components for a measuring apparatus for determining the positions of two structural members which are movable relative to each other, the measuring apparatus including a graduation, a carrier member carrying the graduation and a scanning device for scanning the graduation, wherein the scanning device is guided at a constant distance from the graduation, the scanning device including an assembly base adapted to be fastened to one of the movable structural members, the securing device including spacer members for maintaining the assembly base in an intended position relative to the carrier member, the improvement comprising each of the components of the securing device being a unit which can be separately attached to the carrier member, the components of the securing device being connected to each other in a securing position by means of locking elements provided on the components, the assembly base having ends, each end having a recess, each spacer member being a lug which is mounted on each of the components, the lugs engaging the recesses for supporting the assembly base in a correct position.
- 2. The securing device according to claim 1, wherein the locking elements are a locking projection on one of the components and a recess defined on another of the components.
- 3. The securing device according to claim 1, wherein the locking elements are a slotted projection capable of receiving a screw formed on one of the components and a receiving pocket for said slotted projection defined on another of the components.
- 4. The securing device according to claim 1, further comprising positively locking elements for fixing the components to the carrier member.
- 5. The securing device according to claim 4, wherein the carrier member is a U-shaped hollow section, the hollow section having a side member defining a longitudinal slot, the positively locking elements being projections which act on the side member.
- 6. The securing device according to claim 5, wherein the longitudinal slot is further defined by another side member, the longitudinal slot being located opposite to the projections, the projections being integrally formed with a web member for supporting the components on the another side member.
- 7. The securing device according to claim 1, further comprising frictionally engaging elements on each component for fixing the components to the carrier member.
- 8. The securing device according to claim 7, wherein the carrier member is a hollow section, the frictionally engaging elements being resilient lugs which partially surround the hollow section.
- 9. The securing device according to claim 1, wherein the assembly base including the securing device is mounted on the carrier member in a self-locking manner, wherein the assembly base is movable by the application of an external force.
