Detailed Description
As a first embodiment of the present invention, fig. 1 shows an overall configuration diagram of a gauge 10 as an embodiment of a portable folded-form gauge (a portable folded-form sizing tape). In the figures to be described later, the size of each part of the gauge 10, the angle formed by each part, and the like may be simplified for convenience of description.
The gauge 10 includes first to sixth linear portions, namely, a first linear portion 11, a second linear portion 12, a third linear portion 13, a fourth linear portion 14, a fifth linear portion 15, and a sixth linear portion 16, each of which is a straight edge.
In the present embodiment, as shown in fig. 1 showing the expanded state of the gauge 10, the gauge 10 includes first to sixth linear portions having straight chains and a seventh linear portion 17 serving as a diagonal link.
The gauge 10 further includes, as joint portions, a first joint portion 22, a second joint portion 21, a third joint portion 23, a fourth joint portion 24, a fifth joint portion 25, and a sixth joint portion 26, which are provided at respective longitudinal end portions of the first to sixth linear portions 11 to 16 and which support the adjacent linear portions so as to be rotatable with respect to each other.
The sixth linear portion 16 and the first linear portion 11 of the gauge 10 are connected by a sixth joint portion 26.
In other words, in such a connected state, as shown in fig. 2, the gauge 10 has a structure in which the first to sixth linear portions 11 to 16 are connected in a ring shape by the first to sixth joint portions 22 to 26, respectively.
Here, the ring shape (hereinafter, also referred to as "ring") is formed such that the starting point and the end point are connected to each other to form a circle when they are sequentially connected from the first straight line portion 11 to the sixth straight line portion 16, and is not related to the shape.
In the present embodiment, as shown in fig. 2, the ratio of the lengths in the longitudinal direction of the first straight line portion 11, the second straight line portion 12, the third straight line portion 13, the fourth straight line portion 14, the fifth straight line portion 15, and the sixth straight line portion 16 is L1: l2: l3: l4: l5: l6 ═ 3: 3: 3: 1: 1: 1. here, the distance between both ends of the linear portion, that is, the rotation centers of the first joint portion 22 to the sixth joint portion 26 is defined as "length in the longitudinal direction" L1 of the linear portion sandwiched by the respective joint portions, that is, the first linear portion 11. The length in the longitudinal direction of L2 to L6 is also defined in the same manner.
As described above, in the present embodiment, the first straight portion 11, the second straight portion 12, and the third straight portion 13 have the same length, and the fourth straight portion 14, the fifth straight portion 15, and the sixth straight portion 16 also have the same length.
The first to sixth linear portions 11 to 16 are straight edges, and it is desirable to mark scales and lengths at the positions of the scales as shown in fig. 1, but the structure is not limited to this, and may be a structure without scales as shown in fig. 2 and later in a simplified manner.
Since the first joint 22 to the sixth joint 26 have the same configuration, the description will be made collectively.
As shown in fig. 3 (a) and 3 (b), the first joint section 22 includes: a space portion 31 for fixing a position and provided at an end portion of the first linear portion 11; and a positioning portion 32 provided to be inserted through the gap portion 31.
Fig. 3 (b) is a schematic cross-sectional view of fig. 3 (a) viewed from a different direction.
The first joint part 22 rotatably supports the first linear part 11 and the second linear part 12 by the gap part 31 and a detachable rivet 41 inserted into the gap part 31 and functioning as a positioning part.
Further, in the present embodiment, as shown in fig. 2, in addition to the first linear portion 11 and the second linear portion 12, a seventh linear portion 17 is attached to the first joint portion 22 disposed between the first linear portion 11 and the second linear portion 12.
In the present embodiment, the seventh linear portion 17 is attached to the first joint portion 22, but one end portion of the seventh linear portion 17 may be connected to any one of the first joint portion 22 to the third joint portion 23, which is a joint portion provided at "any one end portion of the first linear portion 11 to the third linear portion 13".
The other end of the seventh linear portion 17 has a connection hole 18, and the connection hole 18 functions as a connection portion that can be connected to any one of the second joint portion 21 to the sixth joint portion 26.
The connection hole 18 is a hole that is opened so that any one of the joint portions other than the first joint portion 22 can be fixed to the position by the positioning portion 32.
By fixing the coupling hole 18 to the positioning portion 32, the gauge 10 can be fixed in various shapes such as a diamond shape and a square shape, as shown in fig. 4 and 5, for example. Note that, in fig. 4, the length of the seventh linear portion 17 is not shown.
In the present embodiment, as shown in fig. 2, when the length of the straight portion from the first joint portion 22 is L7, the connection hole 18 of the seventh straight portion 17 is set so that L1: l7 ═ 1: the mode of v 2 is formed with the first connection hole 181 at a point reaching 1.41421356 times the length of L1. For example, when the length of L1 is set to 90mm, the distance L7 from the first joint part 22 to the first connection hole 181 is substantially 127.28 mm.
Similarly, when the length of L1 is 90mm, the second connection hole 182 is formed at a position where the distance L8 from the first joint 22 to the second connection hole 182 is 90 mm.
Similarly, when the length of L1 is 90mm, the third link hole 183 is formed at a position where the distance L9 from the first joint 22 to the third link hole 183 is 65.5 mm.
Similarly, when the length of L1 is 90mm, the fourth connection hole 184 is formed at a position where the distance L10 from the first joint 22 to the fourth connection hole 184 is 44 mm.
As described above, when the seventh linear portion 17 is connected to the third joint portion 23 so as to connect the first joint portion 22 to the third joint portion 23 by using the first to fourth connection holes 181 to 184, as shown in fig. 4 and 7, the side length of the right triangle formed by the second linear portion 12, the third linear portion 13, and the seventh linear portion 17 is 1: 1: a right-angled equilateral triangle of V2.
When the second connection hole 182 and the third joint portion 23 are connected, as shown in fig. 5 (a), the triangle formed by the second straight portion 12, the third straight portion 13, and the seventh straight portion 17 is formed as a regular triangle, and the gauge 10 is formed as a diamond having a relative angle of 60 ° or 120 °.
Similarly, when the third linking hole 183 and the third joint portion 23 are connected, the gauge 10 forms a diamond shape having an angle of 45 ° formed by the second linear portion 12 and the third linear portion 13, as shown in fig. 5 (b).
Similarly, when the fourth connection hole 184 and the third joint portion 23 are connected, the rule 10 forms a diamond shape having an angle of 30 ° formed by the second linear portion 12 and the third linear portion 13, as shown in fig. 5 (c).
Further, as shown in fig. 6, when the angle of the second joint portion 21 is 90 ° and the angle formed by any of the adjacent linear portions of the third joint portion 23, the fifth joint portion 25, and the sixth joint portion 26 is 180 ° in a state where the fourth joint portion 24 is freely rotatable, the gauge 10 can be formed so that the side length is 3: 4: 5, right triangle.
In addition, when the angle formed by the first joint 22, the second joint 21, the third joint 23, and the sixth joint 26 and any of the adjacent linear portions is 90 °, and the angle formed by the fourth joint 24 and the fifth joint 25 and any of the adjacent linear portions is 180 °, the rule 10 is formed in a square shape.
At this time, when the connection hole 18 is connected to the third joint portion 23 so that the seventh linear portion 17 connects the first joint portion 22 to the third joint portion 23, as shown in fig. 7, the side length of the right triangle formed by the second linear portion 12, the third linear portion 13, and the seventh linear portion 17 is 1: 1: a right-angled equilateral triangle of V2.
As described above, since a plurality of patterns can be easily formed by using the gauge 10, the plurality of patterns can be drawn by a simple configuration and can also be applied to pattern learning and the like.
Further, as a modification of the first to sixth joint portions 22 to 26, as shown in fig. 8, the gauge 10 rotatably supports the linear portions adjacent to each of the first to sixth joint portions 22 to 26 using a removable holed rivet 41 inserted into the gap 31 and spacers 42 different in number in the respective joint portions.
In such a configuration, the first to seventh linear portions 11 to 17 are held by the spacers 42 so as to be able to be accommodated in the linear portions so as to overlap each other in the thickness direction.
The spacer 42 has, for example, the same thickness as the first to sixth linear portions 11 to 16, and four spacers 42 are inserted between the first linear portion 11 and the sixth linear portion 16 in the first joint portion 22.
When storing, as shown in fig. 9, the holed rivet 41 and the spacer 42 at the first joint portion 22 are removed, and the first to sixth linear portions 11 to 16 are folded in a corrugated shape, and then placed so as to overlap the seventh linear portion 17.
In this case, it is preferable to improve the transportability by inserting and fixing an insertion pin or the like that can be inserted through the void portion 31 and the holed rivet 41.
Alternatively, the insert pin 60 may function as the following fixing means: the gauge 10 is fixed by piercing the placement surface D of the gauge 10 in a tack-like manner as shown in fig. 10.
Further, the insert pin 60 may also function as a fixing member: the first joint 22 to the sixth joint 26 are fixed by a predetermined operation such as rotating the hand 61 attached to the upper portion of the insertion pin 60 to be freely retractable from the holed rivet 41 and incorporated in the gauge 10.
In addition, the present embodiment includes: first to sixth linear portions 11 to 16 each formed of a straight edge; and first to sixth joint portions 22 to 26 provided at respective longitudinal end portions of the first to sixth linear portions 11 to 16 and supporting the linear portions adjacent to the first to sixth joint portions 22 to 26 so as to be mutually rotatable.
In the present embodiment, the ratio of the lengths in the longitudinal direction of the first to sixth linear portions 11 to 16 is 3: 3: 3: 1: 1: 1, the first linear portion 11 and the sixth linear portion 16 are connected by a sixth joint portion 26.
According to this configuration, since a plurality of patterns can be easily formed, a plurality of patterns can be drawn with a simple configuration, and the present invention can be applied to pattern learning and the like.
In the present embodiment, the seventh linear portion 17 is provided, one end of the seventh linear portion 17 is connected to the first joint portion 22 provided at the end of the first linear portion 11, and the other end of the seventh linear portion 17 is provided with a connection hole 18 which is a connection portion connectable to any one of the second to sixth joint portions.
According to this configuration, since a plurality of patterns can be easily formed, a plurality of patterns can be drawn with a simple configuration, and the present invention can be applied to pattern learning and the like.
In the present embodiment, when the length L1 of the length L7 from the one end of the seventh straight portion 17 to the connection hole 18 located closest to the other end is 3, L7 is 3 √ 2.
According to this configuration, when the connection hole 18 is connected to the third joint portion 23 so that the seventh linear portion 17 connects the first joint portion 22 to the third joint portion 23, as shown in fig. 7, the right triangle formed by the second linear portion 12, the third linear portion 13, and the seventh linear portion 17 has a side length of 1: 1: a right-angled equilateral triangle of √ 2, and therefore, can be easily formed.
In the present embodiment, the first straight portion 11 and the sixth straight portion 16 are connected by the sixth joint portion 26 in the gauge 10 to form a polygonal ring having the first to sixth straight portions as sides and the first to sixth joint portions as vertexes.
According to this configuration, polygons of various shapes can be formed with one ruler, and a figure can be drawn easily.
Although the preferred embodiments of the present invention have been described above, the present invention is not limited to the specific embodiments described above, and various modifications and changes can be made within the scope of the present invention described in the claims unless otherwise specified in the description.
For example, in the above-described embodiment, the case where the diagonal line is formed as the seventh straight portion of the gauge 10 has been described, but various patterns obtainable by combining the gauges 10 may be formed by connecting to other joint portions.
As shown in fig. 11, the seventh linear portion 17 may be extended to the opposite side of the first joint portion 22, and the grip portion 19 may be provided.
According to this configuration, the gauge 10 can be conveyed while holding the grip portion 19, which contributes to improvement in transportability. The grip portion 19 may be omitted, and the entire length of the seventh linear portion 17 as a diagonal link may be freely changed according to design. For example, the seventh linear portion 17 may be formed to a length such that it does not protrude from the square range when the gauge is formed into a square.
In addition to the holed rivet 41, the method of holding the holed rivet rotatably by fastening with a fastening member such as a screw, a bolt, a nut, or the like may be changed as appropriate according to the design.
The effects described in the embodiments of the present invention are only the most preferable effects obtained by the present invention, and the effects according to the present invention are not limited to the contents described in the embodiments of the present invention.
