Description

Technical Field

[0001] The invention relates to a profile gauge, comprising a shell, in which a plurality of contact pieces are arranged which are movable transversely to the extension direction of the shell, wherein the contact pieces can be moved relative to each other in an adjustment position of a clamping device, wherein a pressure side wall acts on a wide side of a first outermost contact piece, and a wide side of a second outermost contact piece which points away from the first outermost contact piece abuts against a counter-pressure side wall, wherein the clamping device can be placed in a clamping position by rotating a clamping rod about a clamping rod rotation axis, the clamping rod having an eccentric surface which is supported on a supporting side wall, and in the clamping position the contact pieces are clamped between the pressure side wall and the counter-pressure side wall in a manner which prevents the contact pieces from moving relative to each other. Background Art

[0002] A similar profiling gauge is described in DE 10 2021 132 710. The profiling gauge has an elongated housing in which a plurality of contact blades are arranged. The contact blades can be moved relative to the housing and to each other in a direction transverse to the direction in which the housing extends. The contact blades are in contact with each other with their wide sides and can be moved steplessly relative to the housing. The respective ends of the contact blades form measuring ends, through which the contour can be measured. The known profiling gauge can be used for laying floor coverings, such as wooden floors or similar floors. The contact blades can be used to measure protrusions or the like embedded in the room where the floor is to be laid. In the adjustment position, the contact blades can move relative to each other. If the contact blades have measured the contour, the position of the contact blades can be fixed. For this purpose, a clamping device with a clamping rod is provided, which can be rotated from the adjustment position to the clamping position around the clamping rod rotation axis. In the clamping position, the clamping device applies a force to the contact blade. For this purpose, the contact blade is clamped between the pressure side wall and the counter-pressure side wall. The pressure side wall can be formed by a tension element. In order to exert the clamping force, the clamping lever can have an eccentric surface which is supported on the supporting side wall.

[0003] Profile gauges are also known from documents FR 338625, GB 931463, US 2,022,628, US 9,404,726 B2, US 2012 / 0266472 A1, AT 19553, CH 264674, EP 2016364 B1, DE 20 2014 105 871 U1 and DE 102013 019 502 A1. Summary of the invention

[0004] The technical problem to be solved by the present invention is to improve the above-mentioned profiling gauge to make it more practical.

[0005] The technical problem is solved by the invention specified in the claims, wherein each dependent claim is not only an advantageous improvement of the invention specified in the parallel claim, but also provides an independent solution to the technical problem.

[0006] The invention firstly relates to an extended design of a clamping device, by which a contact piece is clamped between a supporting side wall and a mating supporting side wall. All parts of the clamping device are subject to manufacturing tolerances. The contact pieces may also have different material thicknesses due to tolerances. This means that the eccentric surface must cover a relatively large range in order to ensure sufficient mobility between the contact pieces when adjusting the position, and to exert sufficient clamping force on the contact pieces in the clamped position to prevent the contact pieces from moving and to transfer the measured contour to the workpiece. Therefore, the technical problem of the invention is to improve the clamping device in particular so that it can still ensure the function of a profile gauge under large manufacturing tolerances. For this purpose, an adjustable eccentricity of the eccentric surface relative to the rotation axis of the clamping rod is proposed. The eccentric surface itself can be a circumferential surface. The cylindrical surface has a central axis. The central axis is arranged eccentrically relative to the rotation axis of the clamping rod. If the clamping rod is rotated about its rotation axis, the distance between the cylindrical surface and the contact piece or the supporting side wall may change. According to the invention, the distance between the cylindrical surface and the rotation axis of the clamping rod should be adjustable. According to a preferred extension of the present invention, the eccentric surface is formed by the circumference of the pin. The pin can be rotatably assigned to the clamping rod. The pin can be mounted on the clamping rod in an adjustable manner around an adjustment axis eccentric to the eccentric surface. Here, the adjustment axis can be arranged eccentrically relative to the clamping rod axis. In particular, it is provided that the clamping device has a clamping rod rotatable around the clamping rod rotation axis. The clamping rod can carry a pin preferably having a cylindrical circumference. The pin can be rotatably assigned to the clamping rod around the adjustment axis, wherein the adjustment axis is radially offset relative to the clamping rod rotation axis. The adjustment axis is radially offset relative to the contour axis of the eccentric surface formed by the cylindrical circumference. As a result, the eccentricity of the eccentric surface can be adjusted by rotating the pin relative to the clamping rod. In an extension of the present invention, it can be provided that the pin is relatively difficult to move around the adjustment axis relative to the clamping rod. However, it is preferred that the pin is fastened to the clamping rod by a detachable clamping screw and can only be adjusted after the clamping screw is loosened, otherwise the pin is mounted on the clamping rod in a rotationally fixed manner. Thus, the mobility or rotatability of the pin can be adjusted or established by means of the clamping screw. However, it can also be provided that the pin can only be rotated relative to the clamping rod after the clamping screw is loosened. The eccentric surface can act directly on the pressure side wall or even form the pressure side wall itself, for example when the eccentric surface presses on the wide side of the contact blade. In an extended design, it is provided that the pressure side wall cooperating with the eccentric surface of the clamping device is formed by the edge of an elongated hole arranged in the end section of the tension element. The tension element can be a plate-shaped or elongated component, one end of which forms the pressure side wall. The contact blade can have windows through which the tension element extends. An elongated hole can be arranged at the other end of the tension element. The extension direction of the elongated hole is perpendicular to the extension direction of the tension element and therefore perpendicular to the direction of the tension applied to the tension element by the clamping device. If the clamping rod is operated, the eccentric surface, in particular the pin forming the eccentric surface, moves on a circular path around the rotation axis of the clamping rod. Due to the adjustability of the eccentricity, the radius of this circular path can be adjusted.During the rotational movement of the clamping rod, the eccentric surface, in particular the pin forming the eccentric surface, moves in the elongated hole, wherein the pin simultaneously applies a tensile force to the tension element. In an extended design, it is suggested that the end face of the pin, which is away from the head of the pin, is supported on a section of the clamping rod by an intermediate anti-rotation ring, such as a spring ring. The spring ring can be tensioned by the above-mentioned clamping screw. In an extended design of the present invention, it can be provided that the clamping rod forms two bearing sections. The two bearing sections can be spaced apart from each other by a gap. Here, the pin passes through the gap in such a way that the effective section of the eccentric surface is located in the gap. For this purpose, the pin is preferably fastened to the two bearing sections in a suitable manner. The section of the tension element cooperating with the pin can also extend into this gap. It can be provided that the pin has a head, which has a circumferential surface. The circumferential surface of the head can be a cylindrical surface. The center of the cylindrical surface can be located on the adjustment axis. Therefore, the pin can be fastened on both sides to the clamping rod. The bearing section of the clamping rod supports the head, which is rotatably embedded in the cylindrical hole. Another bearing section may have a hole through which the clamping screw passes and is screwed into the end face of the pin. According to a preferred extended design, it can be provided that the clamping rod forms a bearing disk. These bearing disks can form a bearing section. It can be provided that the bearing disk is rotatably connected to the bearing section of the housing part respectively. For this purpose, the bearing projection can be embedded in the supporting groove. According to a preferred design of the present invention, the supporting disk forms grooves away from each other, and the supporting projection is embedded in these grooves. The groove forms edges, which can extend along a circumferential line around the clamping rod rotation axis. These edges can be supported on the supporting projection. It can be provided that the supporting projection is a supporting rib. Preferably, the supporting projection, i.e., preferably the supporting rib is formed by the housing, and the groove is formed by the clamping rod. But it is also feasible that the groove is formed by the housing, and the supporting projection is formed by the clamping rod. According to a preferred extended design, the housing has a structure as described in DE 10 2021 132 7120, so the disclosure of the document is fully incorporated into the disclosure of the present patent application, especially for the structural features in the document are also required here. The housing can have a housing lower part and a housing upper part. The contact piece can be supported movably between the housing lower part and the housing upper part. The tension element can be located between the two housing parts. The housing upper part can have an opening or a hole, which is arranged concentrically with the axis of rotation of the clamping element. The housing lower part can also have a similar opening or a hole. The two openings are particularly used to insert a screwing tool, respectively, to adjust the rotational position of the pin relative to the clamping rod. To this end, the two openings have a sufficiently large opening width so that the screwing tool can be inserted into the head of the pin or the screwing tool engagement hole of the clamping screw in any rotational position of the clamping rod or any adjustment position of the pin. This makes it possible to adjust the eccentricity of the clamping device without disassembling the clamping element or disassembling the housing. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The profile gauge shown in the figure has a housing lower part 24, preferably made of plastic, and a housing upper part 25, also preferably made of plastic. Between the two housing parts 24, 25, there extends an elongated opening in which a plurality of contact blades 2 are arranged. The contact blades 2 are directly in contact with each other via their respective broad sides to form a blade group, and the contact blades 2 can be moved transversely relative to the extension direction of the housing 1 formed by the two housing parts 24, 25.

[0023] The contact blades each have a window. The windows of the contact blades are adjacent to each other so that the tension element 4 can extend through these windows. The tension element 4 is formed by a plate-like plastic component, which forms pressure side walls 12 at both ends. The pressure side walls 12 are in contact with the wide side of the outermost contact blade. The other end 4' of the tension element 4 has a long hole 5. With the help of the tension element 4, force can be applied to the contact blade 2 through the pressure side wall 12.

[0024] The broad side of the contact blade opposite the contact blade in contact with the pressure side wall 12 can be supported on the counter-pressure side wall 6 which is formed in the exemplary embodiment by one or two housing parts 24 , 25 .

[0025] The end section 4' of the tension element 4 is located in the space between the two housing parts 24, 25. A clamping device is provided in this space, by means of which a tensile force can be applied to the tension element 4. The clamping element is formed by a clamping rod 3, which can be rotated about an axis of rotation. The clamping rod 3 carries a pin 8, which is adjustably assigned to the clamping rod 3 about an adjustment axis 10. The adjustment axis 10 extends parallel to the axis of rotation 7, but is radially offset relative to the axis of rotation 7. If the clamping rod 3 is rotated about the clamping rod axis of rotation 7, the adjustment axis 10 moves along a circular line about the clamping rod axis of rotation 7.

[0026] The pin 8 has an eccentric surface 9 which is formed by the circumferential surface of a cylinder. The cylinder forming the eccentric surface 9 has a central axis 29. The adjustment axis 10 is eccentrically offset relative to the central axis 29. The pin 8 is fastened to the clamping rod 3 so that the pin 8 is adjustable about the adjustment axis 10. This means that the distance between the central axis 29 and the rotation axis 7, i.e. the eccentricity of the eccentric surface 9 relative to the rotation axis 7 of the clamping rod, can be adjusted from a minimum distance, in which the central axis 29 is located exactly between the adjustment axis 10 and the rotation axis 7, to a maximum distance, in which the adjustment axis 10 is located between the central axis 29 and the rotation axis 7.

[0027] In this embodiment, an anti-rotation ring or spring ring 27 is provided between the end face of the pin 8 and the wide side of the support disk 14 formed by the clamping rod 3. The end face of the pin 8 has a hole, into which the threaded shank of the clamping screw 11 engages. In addition, the shank of the clamping screw 11 passes through the hole of the support disk 14. The head 11 'of the clamping screw 11 is supported on the opposite side wide side of the support disk 14.

[0028] The support disk 14 has a wide side surface, to which the end surface of the pin 8 is fastened. Opposite to the wide side surface is the wide side surface of another support disk 15. The support disk 15 has a support hole 28, in which the head 13 of the pin 8 is supported. The head 13 has a circumferential surface that is a cylindrical circumferential surface. The center of the cylindrical circumferential surface is the adjustment axis 10 of the pin 8, and the center axis of the clamping screw 11 is also located in the adjustment axis 10. The circumferential surface of the head 13 can be supported on the wall of the support hole 28, so that the pin 8 is fixed to the clamping rod 3 at one end by the clamping screw 11 and is located in the support hole 28 at the other end by the head 13, so that the wall of the support hole 28 can withstand tensile forces.

[0029] The end section 4' of the tension element 4 projects into the gap 17 between the two bearing disks 14, 15. The tension element 4 has there an elongated hole 5, the long sides of which form a supporting side wall 5', on which the eccentric surface 9 of the pin 8 can be supported, in order to exert a tensile force on the tension element 4 when the clamping element 3 is rotated.

[0030] The clamping lever 3 has two bearing sections 14, 15, which in the present embodiment form bearing disks. These bearing sections 14, 15 are rotatably supported on housing parts 24, 25, respectively, for which purpose a bearing projection 21 engages in a bearing recess 19. In the present embodiment, the bearing recess 19 is formed by the two bearing sections 14, 15. The bearing recess 19 each forms an edge 20, which is supported on the bearing projection. In the present embodiment, the bearing projection is formed by a support body 21 in the form of an annular rib. The two annular ribs 21 are formed by the housing lower part 24 or the housing upper part 25.

[0031] The two housing parts 24, 25 also form openings or holes 22, 23. The two openings 22, 23 are aligned with each other and are approximately coaxial with the rotation axis 7 of the clamping lever 3. The two openings 22, 23 have such an opening width that a screwing tool can be inserted through the holes 22, 23. The screwing tool can be inserted into the screwing tool engagement hole 26 of the head 13 or the screwing tool engagement hole of the head 11 'of the clamping screw 11, so as to place the clamping screw 11 in a loose position in which the pin 8 can be rotated about the adjustment axis 10, thereby changing the eccentricity of the eccentric surface 9.

[0032] The anti-rotation ring or spring ring 27 can have sharp projections on its broad side, which on the one hand engage in the broad side of the support disk 14 and on the other hand engage in the end face of the pin 8. In this embodiment, the spring ring 27 forms an anti-rotation ring which prevents the pin 8 from being adjusted relative to the support disk 14 in the clamped position of the clamping screw 11 by a form fit or friction fit. In this embodiment, the pin 8 can only be adjusted after the clamping screw 11 has been loosened.

[0033] The profile gauge shown in the figure also has a guide plate arrangement with two guide plates 30, 31 that can extend from the narrow side of the housing, wherein the guide plate 31 can be moved to reach the opening 23. The guide plate 31 thus closes the opening 23. There are also stops 33, 34, against which the actuating section 3' of the clamping element 3 can rest in each end position. Due to the adjustability of the pin 8 relative to the adjustment axis 10, it is possible to make one of the two stop positions a clamping position in which the contact blades cannot or can only be moved with difficulty relative to each other, while the other stop position is an adjustment position in which the contact blades 2 can be easily moved relative to each other.

[0034] Figures 7 to 9a The possibilities of eccentric adjustment are schematically shown.

[0035] exist Figure 7 In the figure, the dotted line 5' indicates the position of the supporting side wall, and a indicates the distance of the supporting side wall 5' relative to the line passing through the clamping rod rotation axis 7. The eccentric pin 8 is fastened to the clamping rod 3 at the adjustment axis 10. The center axis of the cylindrical eccentric surface 9 is located on the side of the adjustment axis 10 away from the supporting side wall 5', so the distance a is the smallest.

[0036] exist Figure 7a In the pivoted position of the clamping lever 3 shown, the adjustment axis 10 is in the dead center position. The distance a is at its maximum here. This position is the clamping position, and according to Figure 7 The position is the adjustment position.

[0037] Figure 8 and Figure 8a Also shown is the adjustment position ( Figure 8 ) and 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 Figure 8 and Figure 8a The distance a is different in the two pivot end positions.

[0038] exist Fig. 9 and Figure 9a , pin 8 is relative to Figure 7 , Figure 7a The illustration of is adjusted by 90° clockwise about the adjustment axis 10 , so that in the pivot end position the distance a is different again.

[0039] In all figures, the adjustment axis 10 moves along a circle around the clamping lever rotation axis 7 when the clamping lever 3 moves between its two pivot end positions defined by the stop surfaces 33, 34. In all cases, the adjustment axis 10 passes through a dead center position relative to the clamping lever rotation axis 7.
