Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for drawing or marking parallel lines at predetermined intervals on a medium such as a gauge, for example, a cloth for sewing or a drawing paper, or a specific point on the medium. The present invention relates to a gauge used to measure a distance between members and dimensions of various members.

[0002]

2. Description of the Related Art Conventionally, when a line or a mark for cutting is drawn on a fabric, or a line or a mark for defining a seam allowance or a seam is drawn on the cut fabric,
A gauge 7 as shown in FIG. 7 may be used.
The gauge 7 is provided with a slider 7 having a second jaw portion 72 with respect to a main body 7A having an L-shape as a whole with a first jaw portion 71 protrudingly formed at an end of the measuring portion 70.
B is slidably attached so as to embrace the measuring section 70. The scale 70 is provided with a scale in its longitudinal direction, and the scale between the first jaw 71 and the second jaw 72 can be set to a desired value by using the scale. It is configured.

[0003]

However, in the gauge 7 provided for sewing, the first jaw portion 71 is simply provided.
Normally, no means is provided for fixing the slider 7B to the scale 70 so that the distance between the second jaw 72 and the second jaw 72 can be changed. However, since the distance between the first and second jaw portions 71 and 72 may gradually change, there is a problem in reliability.

[0004] In the case of a gauge (calipers) for work,
As shown in FIG. 8, the slider 8B may be configured to be fixed to the scale portion 80 using the set screw 83 in some cases. However, in such a fixing method, when changing the fixed state and the non-fixed state of the slider 8B to each other, a complicated operation such as turning the set screw 83 is required. In particular, in order to ensure the fixed state of the slider 8B, it is necessary to firmly tighten the set screw 83, and the operation is troublesome, and when the fixed state is set to the non-fixed state, the same troublesome operation is required. . Therefore,
In the sewing gauge 7 and the like, the lock mechanism employed in the work gauge 8 and the like can be adopted. However, the sewing gauge 7 has a first jaw portion 71 which is more compared to the work gauge 8. Since it is required that the distance between (81) and the second jaw portion 72 (82) can be easily changed and that it can be manufactured at low cost, the lock mechanism using the set screw 83 is a means that is difficult to adopt.

The present invention was conceived in view of the above-mentioned circumstances, and it is possible to easily select a fixed state and a non-fixed state of a slider in a gauge in which the slider can be moved relative to the main body. Another object of the present invention is to make it inexpensive to manufacture.

[0006]

DISCLOSURE OF THE INVENTION In order to solve the above problems, the present invention employs the following technical means. That is, the gauge provided by the present invention has a main body having a first jaw portion protruding in the width direction of the measuring portion at one end of the measuring portion that is long in one direction, and protruding in the same direction as the first jaw portion. Second
A gauge having a jaw portion and a slider movable along the scale portion, and having a lock mechanism for fixing the slider to the scale portion, wherein the lock mechanism is attached to the scale portion. The slider is fixed to the scale by engaging a protrusion provided on the slider with at least one of a plurality of recesses provided at regular intervals. It is characterized by having.

In such a gauge, the distance between the first jaw portion and the second jaw portion can be adjusted by appropriately selecting the concave portion where the convex portion of the slider is locked using the lock mechanism. it can. Thus, the gauge can be used with respect to a medium such as a sewing cloth or a drawing paper.
It can be used to draw parallel lines or mark at predetermined intervals, and to measure the distance between specific points on the medium and the dimensions of various members. More specifically, it can be used, for example, when measuring the hem-up dimension of pants or the like, setting the interval between tacks and pleats, and marking a buttonhole formation site. If the slider is fixed to the main body by the lock mechanism, the slider does not accidentally move with respect to the main body during use of the gauge. The dimensional reliability when drawing a plurality of is improved.

Further, the lock mechanism locks (fixes) the slider by a simple method such as selecting between a state in which the protrusion of the slider is locked in the groove of the measuring section and a state in which the protrusion is not locked. And a non-locked (non-fixed) state, it is convenient to use. When the main body and the slide are formed of a resin material, a convex portion or a concave portion may be integrally provided during resin molding. Therefore, the above-described lock mechanism can be achieved at low cost.

In such a locking mechanism, for example, a slit extending in the longitudinal direction is provided in the ruled portion, and a first member that covers the back side of the ruled portion and a front surface side of the ruled portion and that extends in the width direction of the ruled portion are provided. A slider is constituted by a second member rotatably held with respect to the first member about the axis, and a protrusion is provided at one end of the second member,
This can be achieved by providing an urging means for urging the convex portion toward the concave portion in a natural state between a portion corresponding to the slit at the other end and the first member.

In the lock mechanism, one end of the slider (the side on which the convex portion is formed) is urged toward the concave portion in the natural state, so that the concave portion is provided unless an external force is applied to the second member. And the slider is locked to the scale. On the other hand, if the second member is rotated by applying an external force to the other end of the second member, the locked state of the convex portion and the concave portion is released, and the unlocked state is established. The slider can be easily slid. As described above, if the lock mechanism is adopted, the slider can be moved by a simple operation such as applying an external force to the other end of the second member, and the slider can be moved only by releasing the external force. The operation can be remarkably improved because such an operation can be performed with one hand.

The main body can be formed of a resin having excellent elasticity such as polycarbonate. In this case, one end of the main body is bent without bending the main body without contacting the entire main body with the medium. Only the part side and the slider can be brought into contact with the medium, and the user can hold the other end side of the main body while holding a line or a mark and measure the size. As described above, since the work such as the positioning of the gauge and the drawing can be performed while holding the other end of the main body, the user does not need to re-grip the main body for each operation in the continuous operation. Also in this respect, workability is improved.

The biasing means can be constituted by a spring-like member such as a leaf spring or a coil spring interposed between the first member and the other end of the second member.

[0013] In a preferred embodiment, the other end of the main body is provided with turning means for turning the measuring section and the slider about the other end.

In this configuration, since one end of the main body, and consequently the slider, can be rotated, if the writing instrument and the like are simultaneously rotated together with the slider and the main body, an arc or a circle can be formed using the gauge. I can draw.

The rotating means is provided by holding a rotating body rotatable with respect to the main body at the other end of the main body, or by projecting a needle-like member from the other end of the main body. . However, when the rotating means is constituted by a needle-shaped member, there is a concern that a hole is opened in a medium such as paper or cloth when the main body is rotated as the center of the rotating means. If it is not permissible to make a hole in the medium, it is preferable to adopt a structure other than a needle-like member such as a structure for holding a rotating body as the rotating means.

In a preferred embodiment, a non-slip means is provided on the back surface of the turning means for suppressing the movement of the turning means with respect to the contact surface.

With this configuration, a situation in which the gauge moves during the drawing of the arc or the circle is appropriately avoided, and the arc or the circle can be drawn as desired.

The non-slip means may be provided, for example, by providing a plurality of grooves or projections on the back surface of the rotating means to make it uneven, or by attaching a member having a large static friction coefficient such as rubber. When the rotating means is constituted by a needle-shaped member, the non-slip means can also be constituted by the needle-shaped member. In addition, also in the non-slip means, similarly to the case of the rotating means, when it is not permitted to make a hole in the medium, or when using a cloth or the like as a medium, when moving the gauge over the medium. It is preferable to employ a means other than the needle-shaped member so that the rotating means and the non-slip means do not catch on the cloth or the like.

In a preferred embodiment, the main body or the slider is provided with a writing instrument holding means.

In the above configuration, the writing implement is fixed by the writing implement holding means, so that the writing implement is appropriately prevented from accidentally moving while drawing an arc or a circle. Arcs and circles can be drawn easily and reliably. Further, since the position of the slider can be changed, if the writing tool holding means is provided on the slider, arcs and circles of various diameters can be drawn by appropriately selecting the position of the slider.

Note that the writing instrument holding means can be provided, for example, by forming a through hole through which a pencil tip or a pen tip can be inserted in the main body or the slider.

In a preferred embodiment, the slit is provided such that its center line is deviated from the center line of the measuring section to one side edge of the measuring section.

In this configuration, the width dimension (first dimension) between one side edge of the slit and one side edge of the measuring section is equal to the width dimension (second dimension) of the other side edge of the slit and the other side edge of the measuring section. ), The gauge has different first and second dimensions. Further, a third dimension obtained by summing the first dimension and the slit width is different from a fourth dimension obtained by summing the second dimension and the slit width. Therefore, if the slit width dimension (fifth dimension) is different from any of the first to fourth dimensions, up to six types of dimensions are defined, including the width dimension (sixth dimension) of the measuring section. It will be. For this reason, the first jaw portion and the second
Even without using the jaw part, it is possible to draw parallel lines at six types of intervals or to mark them. For example, it can be used when securing a seam allowance in sewing or patchwork.

In a preferred embodiment, a pair of the first jaw portions are provided at one end of the main body so as to extend in opposite directions to each other, and the main body has a T-shape having one end edge having a linear region. It is formed in a shape.

In the above configuration, the main body is formed in a T-shape, and a long linear region at one end can be secured. For example, when a relatively long parallel line is drawn, the linear region at one end can be used to move the gauge horizontally. Since a desired parallel line can be drawn by reducing the number of times and distance of shifting, it is convenient.

[0026] Other features and advantages of the present invention will become more apparent from the detailed description given below with reference to the accompanying drawings.

[0027]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A preferred embodiment of the present invention will be specifically described below with reference to FIGS. Here, FIG. 1 is an overall plan view showing an example of the gauge according to the present invention, FIG. 2 is an exploded perspective view showing a slider constituting the gauge of FIG. 1, and FIG. 3 is a sectional view taken along line III-III in FIG. , FIG. 5 is an exploded perspective view in which the vicinity of the rotating means is enlarged, and FIG.
It is sectional drawing which follows the VI-VI line. FIG. 4 is an enlarged sectional view of a main part showing a modification of the urging means.

The gauge 1 according to the present invention has a main body 2, a slider 3, and a rotating body 4, as shown in FIG.

The main body 2 has a pair of first jaws 21 projecting in the width direction at one end 20a of the scale 20 having a substantially constant width which is long in one direction. The main body 2 has a T-shape as a whole, and one end edge (a side of the pair of first jaw portions 21) 21a is straight.

A slit 22 extending in the longitudinal direction deviated to the right side in FIG.
Are formed. The slit 22 has a substantially uniform width, and its width dimension is
2, the width of the right region 20b and the left region 20 in FIG.
c is different from the width dimension. Here, for example, the width of the measuring portion 20 is 1.5 cm, the width of the slit 22 is 0.3 cm, the width of the right region 20b is 0.5 cm,
If the slit 22 is provided so as to be deviated so that the width of the left side region 20c is 0.7 cm, four different dimensions are defined for each part. In addition, the slit 22
And the right side area 20b have a total size of 0.8 cm and a slit 2
Since the total dimension of 2 and the left region 20c is 1.0 cm, if these dimensions are included, a total of six types of dimensions are defined in the width direction of the scale portion 20. As a result, it is possible to draw parallel lines at six types of intervals or to make marks using the part.

The right region 20b and the left region 20
A plurality of first grooves (recesses) 23a and a plurality of second grooves (recesses) 23b each having a triangular cross-section are formed on each of the surfaces of the slits 22 in a longitudinal direction along both edges of the slit 22 and extend in the width direction. Have been. These grooves 23a, 2
3b constitutes a lock mechanism. The ridge line and the valley line of each first groove portion 23a coincide with the ridge line and the valley line of the second groove portion 23b which oppose each other across the slit 22. Here, the groove portions 23a adjacent in the longitudinal direction,
The interval of 23b is appropriately set according to the use of the gauge 1, and for example, in the gauge 1 used as a sewing tool, the interval is about 1 mm. A scale indicating the distance from the rotating body 4 is provided on the surface of the right side region 20b, while the left side region 20c and the first jaw portion 2 are marked.
A scale indicating the distance from one edge 21a is provided on the surface of the first surface.

The other end 20d of the measuring section 20 is provided with a triangular through-hole 24 for holding the rotating body 4 as best seen in FIGS. 1 and 5, and surrounds the through-hole 24. A notch 25 is provided in such a manner.

The main body 2 of the above-described embodiment can be formed simultaneously with the grooves 23a and 23b by, for example, resin molding.

As shown in FIGS. 2 and 3, the slider 3 comprises a first member 30 for covering the back side of the measuring section 20;
And a second member 31 that covers the front side of the second member 31.

The first member 30 has a pair of second jaw portions 33 formed so as to protrude in the width direction of the main body portion 32 and has a T-shape as a whole, and has one end edge (the second jaw portion 33).
The side 33a is a straight line. An upright wall portion 34 is provided on each of both side edges of the main body portion 32, and a through hole 34 a is formed coaxially in each upright wall portion 34.
The distance between the upright wall portions 34 corresponds to the width dimension of the ruled portion 20. When the slider 3 is attached to the ruled portion 20, the distance between the standing wall portions 34 is preferably such that the slider 3 straddles the back side of the ruled portion 20. Body 32
1 and 3, the slider 2 is attached to the main body 2 as best seen in FIGS.
A penetrating hole 34b serving as a writing instrument holding means is formed in a portion which can be accessed through the second through hole 2 so that the tip end of the writing instrument 5 can be held in the through hole 34b.

As shown in FIGS. 2 and 3, the second member 31 has an elongated rectangular plate-shaped main body 35 as a whole. The length dimension corresponds to the distance, and the length dimension corresponds to the length dimension of each upright wall portion 34. A shaft portion 36 extending in the width direction is integrally formed at a central portion in the longitudinal direction of the main body portion 35, and both end portions 36a of the shaft portion 36 protrude in the width direction. The diameter of the shaft portion 36a corresponds to the diameter of the through hole 34a.
By inserting each of “a”, the second member 31 is rotatably supported on the first member 30 about the shaft portion 36. Then, the scale 20 is inserted into the space formed by the first member 30 and the second member 31, and the slider 3 is slidable with respect to the scale 20.

The main body 35 further includes one end 3 on the back side.
A plurality of convex portions 37 are provided on 5a, and a leaf spring portion 38 as an urging means is integrally provided on the other end 35b.
The convex portion 37 and the leaf spring portion 38 constitute a lock mechanism. Each of the protrusions 37 is engaged with each of the grooves 23a and 23b of the scale 20 as shown in FIGS. 1 and 3, has a triangular cross section extending in the width direction, and is formed side by side in the longitudinal direction. Have been. Leaf spring part 38
As shown in FIG. 2 and FIG. 3, the base end 38b side is connected to the other end 35b of the main body 35, and the front end 38a
Is a free end extending toward one end. The distance between the distal end portion 38a and the back surface of the main body portion 35 is set larger than the distance between the through hole 34a of the upright wall portion 34 and the surface of the main body portion 32 in a natural state.

Therefore, in a state where the second member 31 is supported by the first member 30 and no external force is applied to the second member 31, the distance between the leaf spring portion 38 and the main body portion 35 is smaller than the natural state. Therefore, the elastic restoring force of the leaf spring portion 38 applies a force directed upward to the other end 35b of the main body 35. Since the second member 31 is rotatably supported with respect to the first member 30, the main body 35 rotates and the main body 35
A downward force acts on the one end 35a of the first member. As a result, in a state where the slider 3 is attached to the measuring section 20, the respective convex sections 37 are engaged with the predetermined grooves 23a and 23b of the measuring section 20, and the state (locked state) is maintained (see FIG. 3). ). On the other hand, when a downward force is applied to the other end 35b of the main body 35, the main body 35 rotates, and the engagement between the predetermined grooves 23a and 23b and the convex 37 is released. Therefore (see FIG. 3), in this state (unlocked state),
The slider 3 can be slid with respect to zero.

As described above, by appropriately selecting the locked state and the unlocked state, the distance between the one end 21a of the main body 2 and the one end 33a of the slider 3 (first member 30) is set to the left area of the scale 20. Adjust while referring to the scale of 20c,
Further, by selecting the locked state, the once adjusted distance can be appropriately maintained. For this reason, if the slider 3 is slid into the unlocked state to adjust the distance between the one end 21a of the main body 2 and the one end 33a of the first member 30 and then is brought into the locked state, the distance between the one ends 21a and 33a becomes smaller. Because they are properly maintained as desired, they can be drawn or marked at regular intervals with parallel lines. Also, body 2
Is formed in a T-shape, so that the length of one end edge 21a can be ensured to be larger than that in the case of being formed in an L-shape. This means that, by forming the main body 2 in a T-shape, when relatively long parallel lines are drawn at equal intervals, the number of movements or the distance of the gauge 1 in the width direction can be reduced. As a result, usability is improved.

The first member 30 and the second member 31
Are individually formed by, for example, resin molding.

As the urging means, a coil spring 38 'may be employed as shown in FIG. 4, and in this case, the same function as in the case of employing the leaf spring portion 38 can be exhibited. .

The rotating body 4 constitutes a rotating means, and rotates into a triangular through hole 24 provided at the other end 20d of the measuring section 20 as is well shown in FIGS. It is kept possible. As shown in FIGS. 5 and 6, the rotating body 4 has a configuration in which the insertion portion 41 and the locking portion 42 project downward from the center of the base 40, and has a thickness direction at the center. Is provided with a through-hole 43 penetrating through. The base 40 has a disk shape as a whole, and a central portion on the upper surface side is recessed downward. The recessed portion is provided with a plurality of protrusions 40a and two groove portions 40b that intersect at the center of the rotating body 4 (through hole 43). Insertion part 41
Is a diameter corresponding to the shortest distance from the center of the through hole 24 to each side defining the periphery of the through hole 24 and the through hole 24.
Has a thickness corresponding to the depth. The locking portion 42 is formed in a disk shape having a diameter larger than that of the insertion portion 41.
A plurality of projections 42a as anti-slip means are provided on a peripheral portion on the back surface of the device. And the base 40 is

The non-slip means can be constructed by arranging a plurality of projections in a scattered manner or by forming a plurality of slits or grooves.
A material having a large coefficient of static friction such as rubber may be adhered to the back surface of the device. Since the rotating means and the non-slip means having such a configuration do not use a needle-shaped member, there is no possibility that a hole is made in a medium such as paper or cloth, so when drawing a circle or an arc. There is no damage to the media. If the medium such as paper or cloth can be damaged to some extent, the rotating means and the non-slip means should be integrated with the needle-shaped member so as to project downward at the other end of the measuring section. May be provided at the same time.

The above-described rotating body 4 is configured such that after inserting the insertion portion 41 and the locking portion 42 into the through hole 24, the base portion 40 and the locking portion 42 are locked to the peripheral edge of the through hole 24. It is held in the through hole 24. In this case, the through hole 24
Are provided around the through hole 24, and when the rotating body 4 is held, the through hole 24 and the cut 2
Since the space between the members 5 is deformed, the rotating body 4 can be fitted relatively easily, but once the rotating body 24 is once held, it is not easily removed. In the state where the rotating body 4 is held in this manner, the insertion portion 41 is
4 and the peripheral portions of the base portion 40 and the locking portion 42 are locked to the peripheral portion of the through hole 24, respectively. While the diameter of the insertion portion 41 corresponds to the shortest distance between the center of the through hole 24 and each side defining the through hole 24,
Since the thickness of the rotary member 4 corresponds to the depth of the through hole 24, the rotating body 4 is in contact with the inner surface and the peripheral portion of the through hole 24.
For this reason, the rotating body 4 can relatively rotate with respect to the other end 20 d of the measuring section 20 with a predetermined resistance.
Conversely, the shank 20 and thus the body 1 and the slider 2
Rotate around the rotating body 4 (see FIG. 1). At this time, the through hole 24 is formed in a triangular shape and the insertion portion 4 is formed.
Since the area of contact between the first member 1 and the inner surface of the through hole 24 is reduced, an unnecessarily large resistance to the rotation of the rotating body 4 does not occur.

As shown in FIGS. 1 and 3, the first member 30 of the slider 3 has a through hole 3 as a writing instrument holding means.
Since the writing tool 5 is held in the through-hole 34b and, for example, the main body 2 and the slider 3 are rotated around the rotating body 4 while pressing the rotating body 4 with a finger or the like, an arc or a circle is formed. You can draw a circle. Alternatively, as shown in FIG. 6, a circle or an arc may be drawn by inserting a needle 5 'or the like into the through hole 43 and fixing the center of rotation of the gauge 1 to the medium.

Since the rotating body 4 has a groove 40b formed in a cross shape intersecting with the through hole 43, if the rotating body 4 is formed of a transparent resin or the like, for example, the center of rotation (paper or cloth) of the rotating body 4 is formed. The mark 40) and the center of rotation of the main body 2 are
The position can be easily adjusted using the b and the through hole 43. Then, the diameter of the arc or circle drawn by the gauge 1 is adjusted by sliding the slider 3 to the right side area 2 of the scale section 20.
It can be selected using the scale of 0b. Also,
Since the projection 42a is provided on the back surface of the locking portion 41, the displacement of the rotating body 4 with respect to the contact surface is appropriately avoided. Further, the base 40 has a plurality of protrusions 40a.
Is provided, these projections 40a serve as slip stoppers, so that the finger pressing the rotating body 4 is prevented from shifting, and the rotating body 4 is prevented from rotating together with the main body 2 and the like. . As described above, in the gauge 1 of the present embodiment, an arc or a circle can be simply and reliably drawn by various devices applied to the rotating body 4.
