- Target object 100 is used for retroreflection of an optical radiation.
- the target object 100 comprises an all-round reflector consisting of triple prisms 10 .
- the all-round reflector also referred to as a prism ring 1 , is arranged between two holding bodies 3 , 6 .
- the all-round reflector is traversed by a clamping device that can be connected to a plumbing staff.
- the holding bodies 3, 6 are preferably made of an elastic material, preferably a tough elastic material, particularly preferably made of rubber.
- the holding body 3, 6 can therefore also be designated as rubber parts or as a rubber body.
- a first end of the clamping member is free. This first end is referred to as the free end.
- Another end of the Spannor goose, referred to as a plumb pole holder 4, can be connected to the plumb pole.
- a mandrel 9 can form or encompass the free end.
- the free end of the clamping member carries a head piece 19.
- the head piece 19 is in part part of the dome 9.
- the clamping element advantageously comprises the plumbing pole receptacle 4, which is provided, for example, with an internal thread, and the mandrel 9, which is provided, for example, with an external thread section that can be screwed into the internal thread along a thread axis.
- the thread axis is advantageously perpendicular to a plane spanned by the prism ring 1 .
- the thread axis in this case runs parallel to a reference axis which passes through the center of the all-round reflector and runs parallel to the longitudinal extension of the plumbing staff.
- the head piece 19 is in pressure connection with the one holding body 6 .
- the clamping element advantageously also traverses the two holding bodies 3 , 6 .
- the plumbing pole receptacle 4 of the clamping element forms a counterpart that counteracts the pressure via the holding body 3 by virtue of the pressure connection between the head piece 9 and one holding body 6 .
- the mutually facing parts of the all-round reflector and the holding body 3, 6 can be positively connected to one another.
- the mutually facing parts of the all-round reflector and the holding body 3, 6 advantageously interlock in a form-fitting manner. They are pressed together by the compressive force of the compression connection.
- a spring element also referred to as a spring 8 for short, realized by a spring 8, comprising a spring 8 or being surrounded by a spring 8, is arranged between the head piece 9 and one holding body 6, so that the head piece 9 can be connected to the one holding body 6 element is in pressure connection via this spring element, referred to as spring 8 .
- the target object 100 is characterized in particular in that a spring 8 or a spring element is arranged between the head piece 9 and one holding body 6, so that the head piece 9 is in pressure connection with the one holding body 6 via this spring element comprising a spring 8, for example stands.
- the sensitive triple prisms 10, also referred to as glass parts for short, of the all-round reflector, also referred to as prism ring 1, are not mechanically connected to the plumbing pole axis, nor are they connected to a splice designed as damping. Instead, the prism ring 1 is preferably centered by a conical surface 2 on the pole holder 4 and/or the lower rubber part 3.
- An anti-twist device 5 can also be attached.
- an anti-twist device 5 can be arranged between the clamping element and at least one of the holding bodies 3, 6.
- the anti-twist device between the plumbing pole holder 4 and the lower holding body 3 is particularly advantageous.
- a suitable anti-rotation device 5 is, for example, a combination of form-fitting, interlocking, relief-like projections and/or recesses between the plumb pole holder 4 and the lower holding body 3, which, in order to form the anti-twist device 5, are in a predetermined rotational position of the plumb pole holder 4 and the lower holding body 3 with respect to a reference axis about which the anti-rotation device 5 is to be effective, non-rotatably interlock.
- the rubber parts 3, 6 are preferably designed or set free in such a way that no edges and/or corners of the sensitive prism ring 1 can be contacted from the outside.
- the triple prisms 10 of the prism ring 1, also referred to as facets, can be protected all around by the rubber parts 3, 6. As a result, they do not have to be sealed with adhesive, as is the case with the target object previously known from WO 2008/043436 A1.
- Moisture penetrating into the interior of the target object can be drained off through a bore 7, for example.
- the upper rubber part 6 is preferably held in position by a spring 8 .
- the spring force can lead to a constant alignment accuracy of the prisms with one another and against one another, as well as with respect to the perpendicular of the plumbing pole, referred to as prism accuracy. Due to the spring force, the impairment of the prism accuracy through external influences is low.
- the prism ring 1 with the rubber parts 3, 6 can be pretensioned by the spring 8.
- the manufacturing tolerances of the prism ring 1 and the rubber parts 3, 6 can be combined by mutual twisting in such a way that, on the other hand, the smallest possible so-called impact error occurs and/or the influence of the prestressing force on the optical parameters can be minimized.
- the mandrel 9 can then be pressed into the plumbing pole holder 4 .
- Preloading with the spring 8 preferably does not result in any change in the previously measured tolerances.
- the pretensioning force of the spring 8 can be specified depending on the intended use, such as when used on construction machines, etc.
- the best possible centering can be achieved by using preferably only two rotationally symmetrical components.
- the two rotationally symmetrical components are the plumbing pole holder 4 and the mandrel 9.
- FIG. 10b A corner of a triple prism 10 reaching into such a guide slot 33 can be seen in FIG. 10b).
- At least one of the holding bodies 3, 6, also referred to as rubber parts 3, 6, can be provided with guide struts 31, also referred to as protective edges (Fig. 12 , Fig. 13, Fig. 14, Fig. 15, Fig. 16, Fig. 17).
- Fig. 16b it can be seen how such a guide strut 31 of the mutual direction from two adjacent triple prisms 10 is used.
- the triple prisms 10 of the prism ring 1 also called facets, protected all around by the rubber parts 3, 6, but also their edges and corners.
- At least one holding body 3, 6 can comprise external guide struts 31 facing away from the clamping element in the radial direction, between which the individual triple prisms 10 are aligned and arranged with respect to the all-round reflector referred to as the prism ring 1 .
- the guide struts 31 can be arranged in the area of the outer prism edges.
- the holding bodies 3, 6, which are preferably designed as rubber parts, can be aligned radially inwards towards the clamping element, for example towards the thread axis of the mandrel 9.
- the individual parts of the target object 100 are particularly preferably designed in such a way that they can be assembled in a modular manner.
- An advantageous embodiment of the target object 100 also provides that the individual parts of the target object 100 are designed in such a way that they can be detached and/or separated from one another without being destroyed.
- the invention is not limited by the description based on the exemplary embodiments. Rather, the invention encompasses every new feature and every combination of features, which in particular includes every combination of features in the claims, even if this feature or this combination itself is not explicitly specified in the claims or exemplary embodiments.
- the invention is industrially applicable in the field of surveying and in particular in the field of the manufacture of tools and devices for geodesy.
- the invention has been described with reference to preferred embodiments. However, it will be apparent to a person skilled in the art that modifications or variations can be made to the invention without departing from the scope of the following claims.
