Description

[0001] The invention relates to a folding ruler with several ruler sections designed as elongated flat bars, which are connected to each other in pairs at hinges for folding, wherein at least one ruler section has a first side with a first scale marking which has ascending numerical values ​​in a counting direction, and a second side opposite the first side which can be covered by folding, on which a second scale marking is formed which contains ascending numerical values ​​in the counting direction of the first scale marking, wherein the second side which can be covered by folding is provided with a third scale marking which has descending numerical values ​​in the counting direction of the first scale marking.

[0002] Folding rulers, in their extended state, are embodied units of length, the length of which is formed by the two opposing end faces of the end segments. In addition to scale markings, folding rulers often also bear advertising imprints.

[0003] Typically, the segments of folding rulers are marked on both sides with scale markings, each containing numerical values. These numerical values ​​correspond to the distance in centimeters, or another common unit of length, from the end of the ruler to the corresponding mark. The counting direction of the numerical values ​​on the two opposite sides of the ruler is reversed. This ensures that a person measuring a fully opened folding ruler, lying in front of them, only needs to rotate it around its own axis to read a length measurement with the ruler resting on the object being measured and the numerical values ​​counting from left to right.

[0004] Measurements with a folding ruler are often taken not with the ruler fully extended, but with it partially folded. Using a partially folded ruler is convenient when the full length is not needed for a measurement, and even necessary when space constraints prevent the ruler from being fully extended.

[0005] From EP 0 448 506 A2 a folding rule with scale segments is known which have a main scale which has numbers arranged in the middle of the scale segments and which are at least partially provided with an additional scale which is opposite to the main scale.

[0006] In DE 201 19 758 U1, a folding rule with scale segments is specified, each of which is provided with a double scale on its opposite broad sides.

[0007] From US 1,608,713 a folding rule with a multiple scale is known, in which the length of the hypotenuse of a right-angled triangle and the height of a 30-degree angle are entered.

[0008] US Patent 1,028,507 describes a folding ruler with a multiple scale that has a mechanism for locking the scale joints.

[0009] With a folding rule featuring scale markings where each numerical value has only one direction of counting, and this direction differs on each side of the rule, it is not possible to lay a partially unfolded folding rule flat against an object and measure with the numerical values ​​counting from left to right. However, if the folding rule is not laid flat against the object, parallax prevents an accurate length measurement.

[0010] In DE 102 18 553 A1, it is therefore proposed to place two opposing scale markings on one side of the segments of a folding rule, each marking having numerical values ​​whose counting direction is opposite to each other. The numerical values ​​of these two scale markings each correspond to the distance of a line mark located at the numerical values ​​from one of the two opposite ends of the folding rule.

[0011] Because in a middle section of the folding ruler the numerical values ​​of these scale markings on the side with two scale markings are very similar to each other, reading length measurements in this section requires a high level of concentration and reading errors can easily occur there.

[0012] Based on this, the invention aims to provide a folding ruler that enables accurate length measurement even with only partially unfolded ruler sections, without the occurrence of parallax and the risk of reading errors, when the ruler sections are placed against an object for length measurement.

[0013] This problem is solved by a folding rule of the type mentioned above, in which the at least one scale element is connected to an adjacent scale element, which has a first side on which only one scale marking is formed, which is connected to the third scale marking on the first side of the at least one scale element and which has ascending numerical values ​​in the counting direction of the first scale marking, and which has a second side on which only one scale marking is formed, which is connected to the second scale marking on the second side of the at least one scale element and which also has ascending numerical values ​​in the counting direction of the second scale marking.

[0014] One aspect of the invention is to design the markings of the various scale segments on the folding rule in such a way that clear reading is possible despite the different scale markings. To achieve this, it is advantageous to design the first scale segment on the first side of at least one scale segment with a plurality of successive markings, each having a first length and a second length shorter than the first, and to design the scale segment on the first side of the subsequent scale segment with a plurality of successive markings, each having a length corresponding to either the first or second length of the markings of the first scale segment.

[0015] It is advantageous if the numerical values ​​of the first scale marking are indicated by digits that have a foot and a head and are located between the markings of the first length. The foot of the digits points towards the right edge of the scale when viewed in the counting direction. The head of the digits is aligned along an imaginary line that is parallel to the right edge of the at least one scale segment when viewed in the counting direction and that is spaced from the right edge of the at least one scale segment by a distance equal to the first length of the markings of the first scale marking. This ensures that the scale marking on a scale segment with a double scale, including the digits, has a width that corresponds to the width filled with markings on a scale segment with only a single scale.

[0016] Accordingly, the third scale marking on the first side of the at least one scale segment can have a plurality of successive line marks, each with a first length and a second length different from the first. The scale marking on the first side of the further scale segment then contains a plurality of successive line marks with a length corresponding to either the first or second length of the line marks of the third scale marking. Here, too, it is advantageous if the numerical values ​​of the third scale marking are indicated by digits that have a bottom and a top side and are located between the line marks of the first length. Again, the tops of the digits are aligned along an imaginary line parallel to the right edge of the at least one scale segment as viewed in the counting direction.The foot of the digits points towards the right edge of the scale element as seen in the counting direction and is spaced from the right edge of at least one scale element by a distance corresponding to one of the lengths of the first line marks of the third scale mark.

[0017] One idea of ​​the invention is that the numerical values ​​of the first scale marking and the second scale marking on the one hand, and the numerical values ​​of the third scale marking on the other hand, correspond to the distance from different ends of a line mark arranged at the numerical values ​​in the same unit of length measurement, e.g. centimeters.

[0018] It is then possible to take numerical values ​​for length measurements from both ends of the folding rule, with the counting direction increasing relative to each end. This makes it possible, in particular, to avoid the need for mental arithmetic when taking measurements.

[0019] Since the first scale marking on the first side of the at least one scale segment and the third scale marking on the first side of the at least one scale segment have lines extending to a right edge of the at least one scale segment as seen in the counting direction, it is made possible for a measuring person to take a length measurement from one end of the folding rule on an edge of the scale segments facing the measuring person with a counting direction of the numerical values ​​of the scale marking that ascends from left to right.

[0020] The at least one scale element with the two different scale markings on one side can also be connected to another scale element, which is either a start element or an end element. Alternatively, the other scale element can also be connected to an additional scale element, which is either a start element or an end element.

[0021] Preferably, a clear strip extends longitudinally along the side of at least one scale segment between the two scale markings of the at least one, further, and / or additional scale segment. This ensures a clearly visible separation of the different, opposing scale markings, even when the person measuring is at a considerable distance from the folding ruler. The clear strip can be printed with advertising. By adding a marking line to the clear strip separating the two scale markings on the side of the scale segments, it can be made easier for the person measuring to distinguish between the scale markings. Furthermore, it is advantageous if the color of the second and third scale markings on the other side of the at least one scale segment is different.This also helps to counteract the risk of a person measuring confusing scale markings. Alternatively or additionally, at least one of the scale markings can be highlighted with a colored stripe to facilitate easy differentiation. It is advantageous if the scale marking on the second side of the second scale increment and the second scale marking on the second side of the first scale increment are of the same color.

[0022] Preferably, the folding rule consists of ten segments. If the first and last segments, e.g., the first three and the last three, are identical or at least have identical scale markings, then the corresponding segments at both ends of the folding rule have completely identical measuring properties. In principle, it is then irrelevant to the person taking the measurement which end of the folding rule is opened.

[0023] The invention will now be explained in more detail with reference to an exemplary embodiment shown schematically in the drawing.

[0024] They show: Fig. 1 a partially unfolded first folding rule on a base with a view of a first side of unfolded sections of the rule; Fig. 2 the partially unfolded first folding rule on a base with a view of a second side of unfolded sections of the rule opposite the first side; Fig. 3a and Fig. 3b a top view of the side of the folding rule's sections, including a starting section, that is hidden when the folding rule is fully folded; Fig. 4a and Fig. 4b a top view of the in Fig. 3a and Fig. 3b opposite side of the limbs shown; Fig. 5a and Fig. 5b a top view of the side of the folding rule's sections, including an end section, that is hidden when the folding rule is fully folded; Fig. 6a and Fig. 6b a top view of the in Fig. 5a and Fig. 5b opposite side of the limbs shown; Fig. 7 a top view of the segments of a second folding rule with a marking line; and Fig. 8 a top view of the segments of a third folding rule, which has a scale marking underlaid with colored stripes.

[0025] The one in Fig. 1, Fig. 2 and Fig. 3a, b to Fig. The folding rule 10 shown in Figures 6a and b consists of ten consecutive ruler segments 20, ..., 38. The ruler segments 20, ..., 38 are connected to each other in pairs by hinges 18 containing rivets 19 near their end faces 12, 14, at a distance from the end faces 16. The ruler segments 20, 22, ..., 38 are designed as flat bars. The flat bars are made of wood. The rivets 19 extend through aligned hinge bores 40 in the ruler segments 20, ..., 38. The heads of the rivets 19 bear against the broad faces of the ruler segments and press them against each other at their facing broad faces. A locking mechanism arranged in the area of ​​the connected end faces ensures that the ruler segments 20, 22, ...38 interlock in their parallel positions and that a defined friction or braking force is created between the scale members in the intermediate positions.

[0026] The distance A between adjacent joint bores 40 of the folding ruler is preferably 20 cm. The first ruler segment 20 is a starting segment. The last ruler segment 38 is a ending segment. Ruler segments 20 and 38 are preferably 22 cm long. The length L of the remaining ruler segments 22, 24, ..., 36 is the same, preferably 24 cm. The width B of ruler segments 20, 22, ..., 38 is B = 1.6 cm. Their thickness D is 0.3 cm.

[0027] The scale segments 20, 22, ..., 38 have a first side 42 and a second side 44, which is opposite the first side 42. In order for the folding scale 10 to be folded tightly, in the area of ​​a rivet 19, the first side 42 of scale segment 22 faces the second side 44 of scale segment 20, the first side 42 of scale segment 24 faces the second side 44 of scale segment 22, the first side 42 of scale segment 26 faces the second side 44 of scale segment 24, etc.

[0028] When the folding rule 10 is fully folded, the first side 42 of the scale segments 20, 22, ..., 34 is completely covered. The first side 42 of the scale segment 36, however, is partially visible in section 37, and that of the scale segment 38 is fully visible.

[0029] Accordingly, when the folding scale 10 is completely folded, the second side 44 of the scale segments 24 to 38 is completely covered, and the second side 44 of the scale segment 22 is partially visible, while that of the scale segment 20 is completely visible.

[0030] The scale segments 20, 22, ..., 38 are provided on their first side 42 with a first scale marking 46, which extends across all scale segments. The scale marking 46 contains a millimeter scale 47 with a multitude of line markings 50 and a centimeter scale 52, which is also composed of line markings 54. This first scale marking 46 also contains numerical values ​​48, which ascend in a counting direction corresponding to the arrow 51 and which indicate the distance in centimeters of the line markings 50 of the centimeter scale 52 from the end 68 of the scale segment 20 when the folding rule 10 is unfolded.

[0031] On the second page 44, the scale segments 20, 22, ..., 38 have a second scale marking 56. Like the first scale marking 46, this second scale marking 56 also extends across all scale segments 20, 22, ..., 38. The second scale marking 56 contains a millimeter scale 58 with a multitude of line markings 60 and a centimeter scale 62, which is also composed of line markings 64. The second scale marking 54 also contains numerical values ​​66. The numerical values ​​66 indicate the distance in centimeters of the line markings 60 of the centimeter scale 62 from the end 68 of the scale segment 38 when the folding rule 10 is fully extended.

[0032] The counting direction of the numerical values ​​64 of the scale marking 56 corresponds to the counting direction of the numerical values ​​48.

[0033] On the first side 42 of the scale elements 20, 22, 24, in addition to the first scale mark 46, a further, third scale mark 70 is arranged. This third scale mark 70 also contains numerical values ​​72 and has a millimeter scale 74 with a multitude of line marks 76. The third scale mark 70 also has a centimeter scale 76 with line marks 80. The numerical values ​​72 of the third scale mark 70 have a counting direction opposite to that of the first scale mark 46. They correspond to the distance in centimeters of the line marks 76 from the end 82 of the scale element 38.

[0034] The markings 50, 54 of the first scale marking 46 and the markings 76, 80 of the third scale marking 70 on the first side 42 of the scale segments 20, 22, 24 each extend to a right edge 84, 86 of the scale segments 20, 22 and 24 as viewed in the counting direction. This measure enables a person to take a length measurement at the edge 84, 86 of the scale segments 20, 22, 24 facing the person, with a left-to-right counting direction of the numerical values ​​48, 72 of the first and third scale markings 46, 70 on the edge of the folding rule 66 facing the person.

[0035] The first scale mark 46 on the first page 42 of the scale bars 10, 22, 24 has a plurality of successive line marks 31, 33, 35. These line marks 31, 33, 35 have a first length, a second length shorter than the first, and a third length intermediate between the first and second. The scale mark 102 on the first page 42 of the scale bar 26 connected to the scale bar 24 also has a plurality of successive line marks 31', 33', 35', with one of the first, second, and third lengths of the line marks 31, 33, 35 of the first scale mark 46 corresponding to the length of the first, second, and third line marks 31, 33, 35, respectively.

[0036] The numerical values ​​48 of the first scale marking 46 on the scale divisions 20, 22, 24 are indicated by digits 37 located between the first length markings 31, 33. The digits 37 have a head 39 and a base 41. The head 39 of the digits 37 is aligned along an imaginary line 29 parallel to the right edge 84 of the scale division 24 as viewed in the counting direction. Line 29 is spaced from this edge 84 by a distance corresponding to one of the first length markings 31 of the first scale marking 46. The base 41 of the digits 37 points towards the right edge 84 of the scale division 20, 22, 24.

[0037] The same applies to the third scale marking 70 on the first page 42 of scale units 10, 22, 24. Scale marking 70 also has a multitude of consecutive line marks 61, 63, each with a first length and a second length different from the first. Scale marking 70 also has line marks 65 with a third length that lies between the first and second lengths. Scale marking 102 on the first page 42 of scale unit 26 is formed with a multitude of consecutive line marks 31", 33", 35", each with a length corresponding to either the first or second length of the line marks of the third scale marking 70.

[0038] The numerical values ​​72 of scale marking 70 are also indicated by digits 67, which have a head 69 and a base 71. The digits 67 are located between the line marks 61 of the first length. Their head 69 is aligned along an imaginary line 27, which is parallel to a right edge 86 of the scale segments 20, 22, 24 when viewed in the counting direction. The imaginary line 27 is, in turn, spaced from the right edge 86 of the scale segments 20, 22, 24 by a distance corresponding to one of the first lengths of the line marks of the third scale marking 70. The base 71 of the digits 67 points to the right edge 86 of the scale segment 20, 22, 24 when viewed in the counting direction.

[0039] Between the first scale marking 46 and the third scale marking 66 on the first side 42 of the scale segments 20, 22, 24, there is a blank strip 88. This blank strip 88 is preferably 0.5 cm wide. This blank strip 88 provides space for an advertising imprint.

[0040] The scale elements 34, 36, and 38 are marked on their second side 44 with scale marking 56 and a fourth scale marking 90. Scale marking 90 contains numerical values ​​92 and has a millimeter scale 94 with numerous line markings 96. The fourth scale marking 90 also has a centimeter scale 98 with line markings 100. The numerical values ​​92 of the fourth scale marking 90 have a counter-clockwise counting direction to that of the first scale marking 46. The numerical values ​​92 indicate the distance in centimeters of the scale markings 100 from the end 82 of scale element 38.

[0041] On the first side 42 of scale segments 26, 28, 30, and 32, there is only one scale marking 102. Scale marking 102 contains numerical values ​​104 and has a millimeter scale 106 with multiple line markings 108, as well as a centimeter scale 110 with line markings 112. The second side 44 of scale segments 26, 28, 30, and 32 is marked only with the second scale marking 114. Scale marking 114 contains numerical values ​​116 and has a millimeter scale 118 with multiple line markings 120, as well as a centimeter scale 122 with line markings 124. Scale marking 102 is a continuation of scale marking 70 on the first side 42 of segments 20, 22, and 24 of the folding rule. The scale marking 114 continues the scale marking 56 on the second page 44 of the links 20, 22 and 24 of the folding scale.

[0042] The scale markings 70, 56, 102, and 114 on the scale segments 20, 22, ..., 38 of the folding rule are all the same color, e.g., black on a white background. The color of scale markings 46 and 90 is also identical. By using different colors for scale markings 70, 56, 102, and 114 on the one hand, and scale markings 46 and 90 on the other, it is ensured that a person taking measurements will have difficulty confusing these different scale markings.

[0043] The Fig. Figure 7 shows scale segments 220, 222, 224, 226 of a second folding scale 210. The construction of the folding scale 210 corresponds to that shown in the Fig. 1, Fig. 2 and Fig. 3a, b to Fig. The structure of the folding ruler described in sections 6a and b is 10. Corresponding elements are therefore in the Fig. 7 compared to those in Fig. 1 or Fig. The numbers 6, increased by 200, are indicated as reference marks. Folding rule 210 differs from folding rule 10 only in that a marking line 201 is arranged in the blank strip 288 between the first scale marking 246 and the third scale marking 270 on the side 242 of the scale segments 220, 222, 224 that is concealed when the rule is folded. The marking line 201 is located centrally on the side of the scale segments 220, 222, 224. It extends along their length. It alerts the person measuring that the counting direction of the first scale marking 246 and the third scale marking 270 is different, the latter being continued by the scale marking 302 on the scale segment 226.

[0044] The Fig. Figure 8 shows scale segments 320, 322, 324, 326 of a third folding scale 310. The construction of the folding scale 310 also corresponds to that shown in Figure 8. Fig. 1, Fig. 2 and Fig. 3a, b to Fig. The structure of the folding ruler described in sections 6a and b is 10. Corresponding elements are located in the Fig. 8 compared to the Fig. 1 to Fig. 6a, b Numbers increased by 300 are indicated as reference symbols.

[0045] Folding rule 310 differs from folding rule 10 only in that the first scale marking 346 on the side 342 of the scale segments 320, 322, 324, which is concealed when folded, is underlaid with a colored stripe 301. The colored stripe 301 is slightly wider than the length of the first, longer line markings of scale 346. However, the width of the colored stripe 301 is less than half the width of the scale segments 320, 322, 324.

[0046] The color stripe 301 draws the attention of a measuring person that the counting direction of the first scale marking 346 and the third scale marking 390 is different, which continues the scale marking 402 on the scale element 326.

[0047] The described structure of the scale elements 20, 22, 38 of the in the Fig. 1 to Fig. The folding rule 10 shown in Figures 6a and 6b allows the scale segment 20 and scale segment 38, the scale segment 22 and scale segment 36, the scale segment 24 and scale segment 34, the scale segment 26 and scale segment 32, as well as the scale segment 28 and scale segment 30, to be manufactured identically to each other. The folding rule 10 with ten scale segments described above can thus be assembled from five different scale segments, each with a different scale imprint, resulting in a manufacturing advantage. This also applies to the scale segments shown in the Fig. 7 and the Fig.This advantage applies to the 8 folding rulers shown.

[0048] In summary, the following preferred features of the invention can be noted: A folding ruler 10 has several scale segments 20, 22, ..., 38 designed as elongated flat bars, which are connected to each other in pairs at hinges for folding. At least one scale segment 24 of the folding ruler 10 has a first side 112 with a first scale marking 46, which has numerical values ​​48 that increase in one counting direction. On a second side 44 opposite the first side 42, which can be concealed by folding, a second scale marking 56 is formed, which contains numerical values ​​48 that increase in the counting direction of the first scale marking 46. The second side 44, which can be concealed by folding, is provided with a third scale marking 70, which has numerical values ​​72 that decrease in the counting direction of the first scale marking 46. The at least one scale segment 24 is connected to an adjacent scale segment 26.The adjacent scale element 26 has a first side 42 on which only one scale marking 152 is formed, which corresponds to the third scale marking 70 on the first side of the at least one scale element 24, which has ascending numerical values ​​104 in the counting direction of the first scale marking 46. The further scale element 26 has a second side 42 on which only one scale marking 114 is formed, which corresponds to the second scale marking 56 on the second side of the at least one scale element 24, which has ascending numerical values ​​in the counting direction of the second scale marking 56.
