DESCRIPTION OF THE EMBODIMENTS

[0036] The contour gauge illustrated in the figures has a housing 1, which consists of an upper housing part 1 and a lower housing part 1. On the back facing upwards, the upper housing part 1 has a depression running over almost the entire width of the elongated housing 1, which forms a guide 3. The depression has a bottom 5 extending in a plane and a side wall. The side wall has two elongated sections 4 running in a straight line and a rounded end. The end of the guide 3 lying opposite the rounded end is open.

[0037] The lower housing part 1 has the same length as the upper housing part 1. The two housing parts 1 and 1 are connected to one another on their ends. A housing cavity 18 extends between the sections, on which the housing parts 1, 1 are connected to one another. A fin bundle consisting of a plurality of feeler fins 2 is arranged in the housing cavity 18. The feeler fins 2 have the same shape among one another. They consist of flat plastic strips, which have a trapezoidal layout. The feeler fins 2 have a cavity 2, through which a plate 26 extends, which limits the displacement path of the feeler fins 2 in a direction transversely to the direction of extension of the housing 1 on the one hand and which can also absorb a pull on the other hand, when a pressure is applied to the fin bundle by means of two pressure plates 21, 22, so that the individual feeler fins 2, which adjoin one another with contact, can be held in position by means of frictional engagement.

[0038] Two elongated flat rulers 7, 10 lie in the above-described depression, which forms a guide 3. A first ruler 7 bears with a lower broadside surface on the bottom 5. The bottom 5 has a longitudinal slit 6, which extends over almost the entire length of the guide 3 and which has a narrow region 6 and a wider region 6 located therebelow, which is open towards the housing cavity 18. A second ruler 10 bears with its broadside surface, which faces downwards, on the broadside surface of the first ruler 7, which faces upwards. Both rulers 7, 10 have the same width, so that they can adjoin with their narrow outer edges against the side walls 4 of the guide 3.

[0039] A threaded shaft 15 of a clamping screw 15, which has a rectangular, preferably approximately square head 15, is inserted in the longitudinal slit 6. The head 15 lies in the wide region 6 of the longitudinal slit 6. The width of the narrow region 6 of the longitudinal slit 6 corresponds approximately to the diameter of the threaded shaft 15. The width of the wide region 6 of the longitudinal slit 6 corresponds approximately to the distance of two outer edges of the head 15 lying opposite one another, so that the clamping screw 15 is fastened in a rotationally fixed manner and axially fixed manner to the housing. The clamping screw 15, however, can displace within the longitudinal slit 6 in the direction of extension thereof.

[0040] The first ruler 7 as a blunt end and a rounded end. The end can also be formed in an angular manner, however. A bore 8, through which the threaded shaft 15 protrudes, is located in the region of the rounded end. A handle 14 forming a restraining means, which has a flat pressure surface facing the broadside surface of the first ruler 7 facing upwards, is screwed onto the threaded shaft 15. A clamping force can be applied to the first ruler 7 by means of the handle 14. If the first ruler 7 is shifted within the guide 3, the respective position can be fixed by means of the restraining means 14.

[0041] The first ruler 7 has a broadside surface facing downwards, by means of which the ruler 7 bears on the bottom 5. An elongated depression formed by a groove extends over the entire length of the first ruler 7 in the lower broadside surface. This depression forms a wide region 9 of a longitudinal slit 9, which, unlike the depression, is not open on both sides but is closed on both sides. A threaded shaft 17 of a second clamping screw 17 engages through the longitudinal slit 9. A flat head 17 of the clamping screw 17, which has a rectangular or preferably square layout, is located in the depression forming the wide region 9 of the longitudinal slit 9. The depth of the depression is slightly smaller than the material thickness of the head 17, so that the head 17 can be displaced in an essentially unhindered manner in the longitudinal direction with respect to the second ruler 10, wherein the lower broadside surface of the second ruler simultaneously bears on the upper broadside surface of the first ruler. The upper broadside surface of the second ruler 7 thus closes the depression formed by the wide region 9 of the longitudinal slit 9 to form a shaft with a rectangular cross section (see FIGS. 7, 8 and 9).

[0042] The second ruler 10 can be shifted with respect to the first ruler 7, wherein the second clamping screw 17 thereby displaces with respect to the first ruler 7. The threaded shaft 17 of the second clamping screw 17 additionally engages through a bore 11 of the second ruler 10. A second handle 16, which likewise forms a flat pressure surface, which moves against the broadside surface of the second ruler 10 facing upwards when the external thread of the threaded shaft 17 is screwed into an internal thread of the handle 16, is screwed onto the threaded shaft 17 in order to clamp the second ruler 10 against the first ruler 7.

[0043] The guide 3 is open to the top but is engaged over by two protrusions 27 in the region of its edge-side opening. It can also be engaged over by at least one other holder. The two protrusions 27 adjoin an edge region of the second ruler 10. As long as the second ruler 10 is located within the guide 3, it cannot be pivoted with respect to the first ruler 7. It is possible, however, to pivot the second ruler 10 with respect to the first ruler 7 when the connecting point of the second ruler 10 with the first ruler 7 is pulled out of the guide 3.

[0044] The second exemplary embodiment illustrated in FIGS. 24 to 26 has means, by means of which a pivoting of the second ruler 10 with respect to the first ruler 7 is prevented. In addition to the threaded shaft 17, further elements, which engage with the longitudinal slit 9, are provided there in the longitudinal slit 9.

[0045] In the case of the exemplary embodiment, the underside of the second ruler 10 has two protrusions 34, which protrude downwards and which can engage with the longitudinal slit 9. The bore 11, through which a threaded shaft 17 of a clamping screw 17 can engage, is located between the two protrusions 34. The clamping screw 17 has a head 17, which has a diameter. The two protrusions 34 are spaced apart from the bore 11 approximately by the dimension of this diameter.

[0046] In the case of the exemplary embodiment, the protrusions 34 are formed by embossings, which have been created by means of an embossing tool.

[0047] The second exemplary embodiment additionally differs with respect to the first exemplary embodiment by the shape of the head 17, the latter has two flattenings 39 lying opposite one another, which are spaced apart from one another by the width of the longitudinal slit 9, so that the flattenings 39 can adjoin the two walls of the longitudinal slit 9, which leads to a protection against rotation of the clamping screw 17. The free end of the head 17 is formed by two support sections 40 engaging under the edges of the longitudinal slit 9. The front surface of the head 17 has a circular shape.

[0048] The FIG. 25 shows the second clamping screw 17. The first clamping screw 15 can be formed identically.

[0049] The mode of operation of the above-described contour gauge is described on the basis of FIGS. 16-19. The FIG. 16 shows the floor of a room, in which base plates 36 have been installed. An outer edge 36 of a base plate 36 points in the direction of a region, in which base plates 36 have not yet been installed, but in which an interfering object is located. In the exemplary embodiments, these are two pipes 35.

[0050] The FIG. 17 shows the section XVII in FIG. 16 in an enlarged manner. The contour gauge 1 has a distance a to the outer edge 36 of the base plate 36, which is selected randomly. However, the distance a is selected so that the contour of the two pipes 35 can be tapped by means of the feeler fins 2. This takes place by means of a transverse displacement of the feeler fins 2 with respect to the housing 1. The distance a can be tapped by means of the two rulers 7, 10. For this purpose (see FIG. 18), the ruler 10 lying on the top is initially pulled out of the guide completely, until it has reached its stop position, in which the threaded shaft 17 abuts against the end of the longitudinal slit 9. The position of the second ruler 10 is then fixed with respect to the first ruler 7 by means of the restraining means 16.

[0051] After releasing the first restraining means 14, the first ruler 7 is subsequently pulled out of the guide 3as it is shown by the FIG. 19until the stop 13, which is fastened to the free end 12 of the second ruler 10, abuts against the outer edge 36.

[0052] After the tightening of the restraining means 14, 16, the device can be placed onto a base plate 37 to be installed, as it is shown by the FIG. 20. The stop plate 13 can thereby be attached to an outer edge of the base plate 37 to be installed, as the FIGS. 21 and 22 show in an enlarged manner. The tapped contours can then be drawn onto the base plate 37 to be installed by means of a pencil, as it is clarified by the FIG. 23.

[0053] In that a surface of the stop plate 13, which faces to the outside, is used during the tapping of the dimension, and the opposite broadside surface of the stop plate 13 during the marking of the dimension, a slight offset can occur, which is tolerable, however, because the stop plate 13 is generally thinner than the feeler fin 2. In order to compensate for this offset, it is also possible on the other hand, however, to give the stop plate 13 a certain movement play in the direction of extension of the ruler assembly, for example in that pins 33 with a larger axial length are used.

[0054] To restrain the feeler fins 2 to one another, a clamping element is provided that has an eccentric 29 and a clamping lever 28 fastened thereto. The eccentric 29 can be rotated about a housing-fixed axis of rotation. Due to the eccentric layout contour, a pressure can be exerted on the pressure plate 21, which is located between the eccentric 29 and a feeler fin 2 arranged on the edge side of the fin bundle.

[0055] The tension plate 26 engages through the cavities 2 of the feeler fins 2. The tension plate thereby also passes through a longitudinal slit of the pressure plate 21, which can be displaced by rotating the eccentric 29 with respect to the tension plate 26. The end 26 of the tension plate 26 can be pinned to the housing.

[0056] An outermost feeler fin 2, which a second pressure plate 22 adjoins, is likewise located on the other end of the fin bundle. This pressure plate 22 also has a longitudinal slit, through which an end 26 of the tension plate 26 engages, which can be pinned to the housing.

[0057] The FIG. 14 shows the pressure plate 22 in an attached position to a cavity wall 20. In an attached position, the pressure plate 21 lies on an opposite cavity wall 19. When the clamping lever 28 is actuated and the eccentric 29 is rotated, the pressure plate 21 moves away from the housing wall 19 and exerts a pressure, which is directed to the right in the FIG. 14, which pushes the individual feeler fins 2 of the fin bundle against one another. Due to the fact that the material thickness of the feeler fins 2 is subject to tolerances, it may happen that this displacement distance is not sufficient to clamp the feeler fins 2 to one another in a sufficient way.

[0058] A screw is identified with the reference numeral 24. This screw 24 is inserted in a thread insert 23, which is located in the cavity wall 20. The thread insert 23 has an internal thread 23, which engages with the external thread of the screw 24, which is preferably a grub screw. It can be gathered from the FIG. 3 that there is a total of two of these screws 24, which engage with the front end on a broadside surface of the pressure plate 22, in order to displace the pressure plate 22 in the direction of the pressure plate 21, when the screws 24 are rotated by means of a screwing tool 25. The distance between the pressure plates 21, 22 shortens thereby, so that material thickness tolerances of the feeler fins 2 can be compensated.

[0059] It can be gathered from the FIG. 2 that a front side of the housing 1 has a depression 31. This depression 31 has a bottom. The two above-described screws 24 are located in the bottom.

[0060] A stop 13 is fastened to the free end 12 of the second ruler 10. The stop 13 has an angle-shaped stop carrier 13, which is fastened to the free end 12 of the second ruler 10 by means of a rivet, a screw or the like. A leg of the stop carrier 13, which protrudes downwards therefrom at a right angle, forms a bearing surface, which a stop plate 13 adjoins. The stop plate 13 has a lower outer edge 32 and two longitudinal slits 34, through which a pin 33 or a screw engages in each case, by means of which the stop plate 13 is fastened to the bearing surface of the stop carrier 13. The stop plate 13 can be displaced in the vertical direction between a storage position, in which the stop plate 13 can lie in a depression 31 of the housing, into a use position, in which the lower outer edge 32 bears on a floor, to which the housing 1 is attached.

[0061] A distance a to very flat floor coverings can also be tapped by means of this vertical displaceability of the stop plate 13.

[0062] In the case of the exemplary embodiment, the ruler assembly has two rulers lying one on top of the other. It is also possible, however, to place several rulers one on top of the other, whereby the rulers lying directly on top of one another can be shiftable with respect to one another.
