Description

Description Contour gauge field of technology

[0001] The invention relates to a contour gauge with a housing in which a plurality of sensing blades are arranged which can be displaced transversely to the direction of extension of the housing, wherein the sensing blades are displaceable relative to one another in a setting position of a clamping device, wherein a pressure flank of a tension element engages a broad side surface of a first outermost sensing blade, and a broad side surface of a second outermost sensing blade facing away therefrom bears against a counter-pressure flank, wherein the clamping device can be brought into a clamping position by rotating a clamping lever about a clamping lever rotation axis, which has an eccentric surface which is supported on a support flank, in which the sensing blades are clamped between the pressure flank and the counter-pressure flank in a manner which inhibits the displacement of the sensing blades relative to one another. State of the art

[0002] A contour gauge of this type is described, among others, in DE 102021 132 710. The contour gauge described therein has an elongated housing in which a plurality of sensing blades are arranged. The sensing blades are movable relative to the housing and relative to each other in a direction transverse to the direction of extension of the housing. The sensing blades are in contact with each other with their broad sides and can be moved continuously relative to the housing. The respective ends of the sensing blades form sensing ends with which a contour can be sensed. The known contour gauge can be used for the installation of Floor coverings, for example parquet tiles or the like. The sensing slats can be used to detect projections or the like that extend into the room on whose floor the floor covering is to be laid. In an adjusted position, the sensing slats can be moved against each other. Once the contour has been detected with the sensing slats, the position of the sensing slats can be fixed. For this purpose, a clamping device with a clamping lever is provided, which can be moved from the adjusted position into a clamped position by rotating about a clamping lever axis. In the clamping position, a force is exerted on the slat pack. For this purpose, the slat pack is clamped between a pressure flank and a counter-pressure flank. The pressure flank can be formed by a tension element. To exert the clamping force, the clamping lever can have an eccentric surface that is supported on a support flank.

[0003] Contour gauges are known, among others, from FR 338625, GB 931463, US 2,022,628, US 9,404,726 B2, US 2012 / 0266472 A1, AT 19553, CH 264674, EP 2016364B1, DE 202014 105871 U1 and DE 102013 019502A1. Summary of the invention

[0004] The invention is based on the object of improving the contour gauge described at the beginning in a manner that is advantageous for use.

[0005] The problem is solved by the invention specified in the claims, wherein the subclaims are not only advantageous developments of the invention specified in the independent claims, but also represent independent solutions to the problem.

[0006] The invention initially relates to a further development of the clamping device with which the plate pack is clamped between the pressure flank and the counterpressure flank. All parts of the clamping device are subject to manufacturing tolerances. The plates can also have different material thicknesses due to tolerances. This means that the eccentric surface must cover a relatively large area in order to ensure, on the one hand, sufficient displacement of the plates relative to one another in the setting position and, on the other hand, to exert sufficient clamping force on the plate pack in the clamping position so that the plates cannot shift and the measured contour can be transferred to a workpiece. The invention is therefore based in particular on the object of further developing the clamping device in such a way that the functionality of the contour gauge is sufficiently guaranteed even with larger manufacturing tolerances.For this purpose, it is proposed that the eccentricity of the eccentric surface is adjustable relative to the clamping lever rotation axis. The eccentric surface itself can be a cylindrical surface. This cylindrical surface has a central axis. This central axis is arranged eccentrically to the rotation axis of the clamping lever. If the clamping lever is rotated about its rotation axis, the distance of the cylindrical surface to the disk pack or the support flank can change. The distance between the cylinder axis and the rotation axis of the clamping lever should be adjustable according to the invention. According to a preferred development of the invention, the eccentric surface is formed by a jacket surface of a pin. The pin can be assigned to the clamping lever in a rotationally adjustable manner. It can be seated on the clamping lever so that it can be adjusted about an adjustment axis arranged eccentrically to the eccentric surface. The adjustment axis can be arranged eccentrically relative to the clamping lever axis.In particular, it is provided that the clamping device has a clamping lever. which is rotatable about a clamping lever rotation axis. The clamping lever can carry the pin, which preferably has a cylindrical jacket surface. The pin is assigned to the clamping lever so that it can be rotated about an adjustment axis, wherein the adjustment axis is radially offset with respect to the clamping lever rotation axis. The adjustment axis is in turn radially offset with respect to a contour axis of the eccentric surface of the pin, which is formed by a cylindrical jacket surface. This has the result that the eccentricity of the eccentric surface can be adjusted by rotating the pin relative to the clamping lever. In a further development of the invention, it can be provided that the pin is difficult to adjust about the adjustment axis relative to the clamping lever. However, it is also preferred that the pin is attached to the clamping lever with a detachable clamping screw and can only be adjusted after loosening the clamping screw and otherwise sits on the clamping lever in a rotationally fixed manner.The stiffness or, preferably, rotatability can thus be adjusted or established using the clamping screw. However, it is also provided that the pin can only be rotated relative to the clamping lever after the clamping screw has been loosened. The eccentric surface can act directly on the pressure flank or even form one itself, e.g. when the eccentric surface comes into contact with the broad side surface of a slat. In a further development, it can be provided that the support flank, with which the eccentric surface of the clamping device interacts, is arranged at the edge of an elongated hole arranged in an end section of the tension element. The tension element can be a plate or an elongated component which forms the pressure flank at one end. The sensing slats can have windows through which the tension element extends. The elongated hole can be arranged at the other end of the tension element.The extension direction of the elongated hole runs transversely to the extension direction of the tension element and thus transversely to the extension direction. the tensile force exerted by the tensioning device on the tensioning element. When the tensioning lever is actuated, the eccentric surface and in particular the pin forming the eccentric surface moves on a circular path around the rotational axis of the tensioning lever. Due to the adjustability of the eccentricity, the radius of this circular path can be set. During the rotational movement of the tensioning lever, the eccentric surface and in particular the pin forming the eccentric surface moves in the elongated hole, with the pin simultaneously exerting a tensile force on the tensioning element. In a further development, it is proposed that an end face of the pin facing away from a head of the pin is supported on a section of the tensioning lever with the interposition of an anti-rotation ring, e.g. a spring ring. The spring ring can be tensioned by means of the aforementioned clamping screw. In a further development of the invention, it can be provided that the tensioning lever forms two bearing sections.The two bearing sections can be spaced apart from each other by a gap. The pin engages through the gap in such a way that an effective section of the eccentric surface is located in the gap. For this purpose, the pin is preferably attached to both bearing sections in a suitable manner. The section of the tension element that interacts with the pin can also extend into this gap. The pin can be provided with a head that has a circumferential surface. The circumferential surface of the head can be a cylindrical surface. The center of this cylindrical surface can lie on the adjustment axis. The pin can thus be attached to the tension lever on two sides. One bearing section of the tension lever supports the head, which lies rotatably in a cylindrical bore. The other bearing section can have a bore through which a clamping screw extends, which is screwed into an end face of the pin.According to a preferred further development, it can be provided that the. The tension lever forms bearing disks. These bearing disks can form the bearing sections. It can be provided that the bearing disks are each rotatably connected to sections of a housing part. For this purpose, bearing projections can engage in bearing recesses. According to a preferred embodiment of the invention, the bearing disks form the recesses pointing away from one another into which the bearing projections engage. The recesses form edges that can extend on a circular line around the tension lever axis of rotation. These edges can be supported on the bearing projections. It can be provided that the bearing projections are bearing ribs. The bearing projections, i.e. the preferred bearing ribs, are preferably formed by the housing and the recesses by the tension lever. However, it is also possible for the recesses to be formed by the housing and the bearing projections by the tension lever.According to a preferred development, the housing has a design as described in DE 102021 1327120, which is why the disclosure of this document is fully incorporated into the disclosure of this patent application, in particular in order to claim the design features therein here as well. The housing can have a lower housing part and an upper housing part. The sensing blades can be displaceably mounted between the lower housing part and the upper housing part. The tension element can be located between the two housing parts. The upper housing part can have an opening or bore arranged concentrically to the rotational axis of the clamping element. The lower housing part can also have such an opening or bore. The two openings are provided in particular for the insertion of a screwing tool with which the rotational position of the pin relative to the clamping lever can be adjusted.For this purpose, the two openings have a sufficiently large opening width so that the screwing tool. In any rotational position of the clamping lever or in any adjustment position of the pin, it can be inserted into the screw tool engagement openings in the head of the pin or the clamping screw. This makes it possible to adjust the eccentricity of the clamping device without having to remove the clamping element from the housing or disassemble the housing. Short description of the drawings

Description of the embodiments

[0008] The contour gauge shown in the drawings has a lower housing part 24, made in particular of plastic, and an upper housing part 25, also preferably made of plastic. Between the two housing parts 24, 25 extends an elongated opening in which a plurality of sensing blades 2 are located. The sensing blades 2 form a blade package. from touch slats 2 which are in direct contact with one another with their respective broad sides and which are displaceable transversely relative to the direction of extension of the housing 1 formed by the two housing parts 24, 25.

[0009] The sensing blades each have a window. The windows of the sensing blades are arranged next to one another in such a way that a tension element 4 can extend through the windows. The tension element 4 is formed by a plate-shaped plastic object that has a pressure flank 12 at one of its two ends. The pressure flank 12 rests against a broad side surface of an outermost sensing blade. The other end 4' of the tension element 4 has an angled hole 5. The tension element 4 can exert a force on the stack of sensing blades 2 via the pressure flank 12.

[0010] The broad side surface of the sensing blade opposite the pressure flank 12 can be supported on a counter-pressure flank 6, which in the exemplary embodiment is formed by one or both housing parts 24, 25.

[0011] The end section 4' of the tension element 4 is located in a space between the two housing parts 24, 25. In this space is a tensioning device with which a tensile force can be exerted on the tension element 4. The tensioning element is formed by a tension lever 3, which can be rotated about a rotation axis. The tension lever 3 carries a pin 8, which is assigned to the tension lever 3 and is adjustable about an adjustment axis 10. The adjustment axis 10 runs parallel to the rotation axis 7, but is radially offset from the rotation axis 7. If the lever 3 is rotated around the clamping lever rotation axis 7, the adjustment axis 10 moves on a circular arc around the clamping lever rotation axis 7.

[0012] The pin 8 has an eccentric surface 9, which is formed by an outer surface of a circular cylinder. The circular cylinder forming the eccentric surface 9 has a central axis 29. The adjustment axis 10 is eccentrically offset with respect to the central axis 29. The pin 8 is attached to the clamping lever 3 in such a way that the pin 8 can be adjusted around the adjustment axis 10. This has the result that the distance between the central axis 29 and the axis of rotation 7, i.e. the eccentricity of the eccentric surface 9 with respect to the clamping lever axis of rotation 7, can be adjusted from a minimum distance at which the central axis 29 lies exactly between the adjustment axis 10 and the axis of rotation 7, to a maximum distance at which the adjustment axis 10 lies between the central axis 29 and the axis of rotation 7.

[0013] In the exemplary embodiment, an anti-rotation ring or spring ring 27 is located between an end face of the pin 8 and a broad side surface of a bearing disk 14 formed by the clamping lever 3. The end face of the pin 8 has a bore into which a threaded shaft of a clamping screw 11 engages. The shaft of the clamping screw 11 also passes through a bore in the bearing disk 14. The head 11' of the screw 11 rests on the opposite broad side surface of the bearing disk 14.

[0014] The bearing disc 14 has a broad side surface to which the end face of the journal 8 is attached. A broad side surface of another bearing disc 15 extends opposite this broad side surface. The bearing disc 15 has a bearing bore 28 in which a head 13 of the journal 8 is mounted. Head 13 has a cylindrical surface. The center of the cylindrical surface is the adjustment axis 10 of pin 8, within which the center axis of clamping screw 11 also extends. The cylindrical surface of head 13 can be supported on the wall of the bearing bore 28, so that pin 8 is secured to the clamping lever 3 at one axial end by the clamping screw 11, and at the other axial end, the head 13 rests in the bearing bore 28, allowing the wall of the bearing bore 28 to absorb tensile forces.

[0015] The end section 4' of the tension element 4 protrudes into the space 17 between the two bearing discs 14, 15. There, the tension element 4 has an elongated hole 5, the longitudinal side of which forms a support flank 5', against which the eccentric surface 9 of the pin 8 can rest in order to exert a tensile force on the tension element 4 when the clamping element 3 rotates.

[0016] The tensioning lever 3 has two bearing sections 14, 15, which form bearing discs in the exemplary embodiment. These bearing sections 14, 15 are each rotatably mounted on a housing part 24, 25, for which purpose a bearing projection 21 engages in a bearing recess 19. In the exemplary embodiment, the bearing recesses 19 are formed by the two bearing sections 14, 15. The bearing recesses 19 each form an edge 20, which is supported on a bearing projection. In the exemplary embodiment, the bearing projection is formed by a bearing body 21 in the form of an annular rib. The two annular ribs 21 are formed by the lower housing part 24 and the upper housing part 25, respectively.

[0017] The two housing parts 24, 25 also form openings or bores 22, 23. The two openings 22, 23 are aligned with one another and approximately coaxial with the rotational axis 7 of the clamping lever 3. The two openings 22, 23 have an opening width such that a screwing tool can be inserted through the bores 22, 23. The screwing tool can engage in a screwing tool engagement opening 26 of the head 13 or in the screwing tool engagement opening of the screw head 11' in order to bring the clamping screw 11 into a release position in which the pin 8 can be rotationally adjusted about the adjustment axis 10 in order to change the eccentricity of the eccentric surface 9.

[0018] The anti-rotation or spring ring 27 can have sharp-edged projections on its broad side surfaces, which engage, on the one hand, with the broad side surface of the bearing disc 14 and, on the other hand, with the end face of the pin 8. In this embodiment, the spring ring 27 forms an anti-rotation ring, which, with positive locking means or frictional locking means, prevents the pin 8 from being adjusted relative to the bearing disc 14 when the clamping screw 11 is in a clamped position. In this embodiment, the pin 8 can only be adjusted by first loosening the clamping screw 11.

[0019] The contour gauge shown in the drawings has a ruler arrangement with two rulers 30, 31 that can be extended from a narrow side of the housing, whereby the ruler 31 has to be moved in order to gain access to the opening 23. The ruler 31 thus closes the opening 23. In addition, stops 33, 34 are provided, against which an actuating section 3' of the clamping element 3 can strike in each end position. By means of the adjustability of the pin 8 relative to the adjustment axis 10, it is possible that a of the two stop positions is a clamping position in which the sensing blades cannot be moved against each other or can only be moved with difficulty and the other stop position is an adjustment position in which the sensing blades 2 can be easily moved against each other.

[0020] Figures 7 to 9a schematically illustrate the possibilities offered by the eccentric adjustment.

[0021] In Figure 7, the dashed line 5' indicates the position of a support flank; a denotes the distance of the support flank 5' relative to a line drawn through the clamping lever rotation axis 7. The eccentric pin 8 is attached to the adjustment axis 10 on the clamping lever 3. The center axis of the cylindrical eccentric surface 9 lies on the side of the adjustment axis 10 facing away from the support flank 5', so that the distance a is minimal.

[0022] In the pivoted position of the clamping lever 3 shown in Figure 7a, the adjustment axis 10 assumes an over-center position. The distance a is at its maximum here. This position is the clamping position, while the position shown in Figure 7 is the adjustment position.

[0023] Figures 8 and 8a also show an adjustment position (Figure 8) and a clamping position (Figure 8a). However, here the pin 8 is pivoted 90° counterclockwise about the adjustment axis 10 relative to the clamping lever 3, so that different distances a result in the two pivot end positions shown in Figures 8 and 8a.

[0024] In Figures 9 and 9a, the pin 8 is adjusted clockwise by 90° about the adjustment axis 10 compared to the illustrations in Figures 7, 7a, so that again different distances a result in the swivel end positions.

[0025] In all figures, the adjustment axis 10 moves along a circular arc around the clamping lever rotation axis 7 when the clamping lever 3 is moved between its two pivoting end positions defined by the stop surfaces 33, 34. In all cases, the adjustment axis 10 overruns a dead center position relative to the clamping lever rotation axis 7.
