Description

  The present invention relates to a tape measure and a contact jig attached to the tape measure.

  A conventional tape measure is to draw out a tape-shaped ruler that has been wound up, measure the dimensions of the object to be measured, and rewind it. When copying the dimensions of a measurement object to another object using a tape measure, a human must read the dimensions and store the dimensions. Alternatively, a human must transfer the dimension to another object while holding the dimension scale of the measuring object of the tape measure with a finger.

  In addition, the measurement of the internal dimension is inconvenient and the measurement of the internal dimension is inaccurate because it is necessary to bend the tape measure of the tape measure at 90 degrees.

Embodiment 1 FIG.
FIG. 1 is a diagram showing a tape measure 50 according to the first embodiment.
The tape measure 50 is sometimes called a convex, a scale, or a measure.
The tape measure 50 has a tape measure case 53. The tape measure case 53 accommodates the band measure 51.
The tape measure 50 is an automatic winding type.

The tape measure case 53 pulls out and rewinds the band measure 51 from the loading / unloading port 55.
The button 54 locks or releases the band 51 by being turned on and off.

  The belt measure 51 is constantly rewound by a leaf spring or a mainspring (not shown) in the tape measure case 53. With the button 54 locked, the pulled-out state of the band 51 is fixed. The band measure 51 is rewound by the release of the button 54.

  The band measure 51 is a steel ruler (steel tape) and can return to a straight line shape even if it is bent. The band measure 51 has a cross section orthogonal to the longitudinal direction curved in an arc shape. The strip 51 has a curved concave surface as a front surface and a curved convex surface as a back surface.

  The band measure 51 is a band in which a scale and a number are given to an arcuate curved concave surface, and the scale and the number are written in either the metric method or the scale penetration method, or both. The scale is a scale with an equal interval of 1 mm, for example.

  A tongue-shaped hook plate 40 is provided at the tip of the band 51. The hook plate 40 has a substantially rectangular shape and is a stainless steel plate. The hook plate 40 is attached at right angles to the band 51 by an attachment edge 41. There is a pulling edge 42 on the opposite side of the mounting edge 41. The pulling edge 42 is a portion where a person hooks a finger when pulling out the band measure 51.

  The front surface 43 and the rear surface 44 of the hook plate 40 are surfaces that come into contact with the measurement object.

FIG. 2 is a view showing the contact jig 90.
The contact jig 90 includes a body 60 and a contact plate 70.
The contact jig 90 can be manufactured by shearing a stainless steel plate into a T-shape and bending the head portion to be the contact plate 70 at 90 degrees.

  The thermal expansion coefficient of the contact jig 90 is desirably the same as the thermal expansion coefficient of the strip 51. It is desirable that the contact jig 90 and the strip 51 are the same or the same material.

  The body 60 is a single flat plate. In the body 60, the front protrusion 61, the fixing part 62, and the rear protrusion 63 are on the same plane and are continuous.

The contact portion 80 includes a front protruding portion 61 and a contact plate 70. The contact portion 80 protrudes from the lower portion of the inlet / outlet port 55 in the direction in which the strip 51 is pulled out.
The front protrusion 61 and the contact plate 70 of the contact part 80 are on the curved convex surface side of the band 51.
There is a backing plate 70 at the front end of the front protrusion 61. The backing plate 70 has a substantially concave shape.

  The base portion 72 is a flat plate in which the guide portions 71 are arranged on both sides and the two guide portions 71 are connected.

  The contact plate 70 is bent so as to be orthogonal to the front protruding portion 61 at the upper portion of the base portion 72 (groove bottom of the recess). The contact plate 70 is bent in the same direction (downward) as the hook plate 40. The convex part of the curved convex surface of the band 51 slides on the upper part of the base part 72 (the groove bottom of the concave part).

  The guide portion 71 is a pair of parallel plates provided upright on both sides of the contact plate 70. The guide part 71 guides the left and right sides of the strip 51 by sliding both ends of the strip 51 on the inner side surface of the guide 71 facing each other.

  The front surface 73 and the back surface 74 of the backing plate 70 are surfaces that contact the measurement object.

FIG. 3 is an AA longitudinal sectional view in which the inside of the tape measure 50 of the first embodiment is omitted.
FIG. 3 shows a state where the band measure 51 is rewound.

In the unwinding state, the hook plate 40 is caught by the contact plate 70.
That is, the front surface 73 of the contact plate 70 is in contact with the back surface 44 of the hook plate 40, and the strip 51 is drawn out by the length L protruding from the contact portion 80 in the unwinding state.

  And in the rewinding state, the base 72 protrudes the pulling edge 42 for pulling out the strip 51 with a finger.

  The lower surface of the fixing portion 62 is bonded and fixed to the upper surface of the bottom portion of the tape measure case 53. The bottom side of the entrance / exit 55 is on the upper surface of the bottom of the tape measure case 53. The front protrusion 61 protrudes from the bottom side of the inlet / outlet port 55 in the pull-out direction.

  The strip 51 is pulled out from the upper part of the entrance / exit 55.

  Thus, in the state where it was rewound, the front protrusion 61, the bottom plate 56, and the strip 51 are parallel.

  The thickness of the bottom plate 56 of the tape measure case 53 (height from the bottom surface of the bottom plate 56 to the bottom side of the inlet / outlet port 55) is a level difference E, but the level difference E should be as small as possible. That is, it is preferable that the bottom plate 56 and the front projecting portion 61 be arranged so as to be as flush as possible.

  The rear protrusion 63 extends straight from the rear of the tape measure case 53.

  FIG. 4 is a view showing the hook plate 40 and the contact plate 70 as seen from the B direction (drawing direction / rewinding direction) in FIG.

The meaning of each symbol is as follows.
L1: The width of the contact plate 70 L2: The distance between the guide portions 71 L3: The width of the hook plate 40 and the strip 51 (the width of the hook plate 40 is the same as the width of the strip 51)
L4: Width of the front protrusion 61 M1: Height of the contact plate 70 M2: Height from the front protrusion 61 to the top (upper side) of the guide portion 71 M3: Height of the base 72 N1: Height of the hook plate 40 N2: thickness of the mounting edge 41 (curved thickness of the strip 51, ie, the height of the arc)
N3: Hook length of the hook plate 40 N4: Length of the pulling edge 42

The size relationship of each part is as follows.
L1>L2>L3> L4
M1 = M2 + M3
N1 = N2 + N3
N4 = N3-M3
N4> 0

Moreover, the following length relationship arises for the following reasons.
L2> L3: There is a slight gap so that the guide portion 71 does not interfere with the insertion and removal of the strip 51 due to friction. That is, the inner side wall 75 of the guide portion 71 is disposed about 0.2 mm to 1 mm away from both side portions 52 in the width direction of the strip 51. That is, L2 is larger than the length obtained by adding 0.4 mm to L3 and smaller than the length obtained by adding 2 mm to L3.

  L3> L4: The writing instrument is allowed to enter under the band 51. When L3 ≦ L4, the tip of the writing tool hits the band 51 and it is difficult to mark the object with the writing tool.

  M3> 0: Since the base 72 exists in the downward direction, the base 72 can be measured by being caught on the measurement object. That is, measurement can be performed by pressing the front surface 73 or the back surface 74 of the base 72 against the measurement object. When M3 = 0, that is, when the base 72 does not exist, measurement cannot be performed without being caught on the measurement target.

  M2 ≧ N2: In order for the guide part 71 to guide the insertion and removal of the band measure 51, the guide part 71 may be the same height as both ends of the band measure 51. However, if M2> N2, the band measure 51 is the guide part 71. It becomes difficult to come off.

  N4 = N3-M3: N4> 0 must be satisfied in order for the pulling edge 42 to be a hook for hooking a finger.

FIG. 5 is a diagram showing a marking method using the band measure 51 and the contact plate 70.
As shown in FIG. 5A, the writing tool is placed on the surface 73 of the patch plate 70 under the tape measure 51, and the tip of the writing tool is submerged to mark the object underneath.

  Similarly, as shown in FIG. 5B, since L3> L4, the writing tool is inserted into the back surface 74 of the backing plate 70 and the tip of the writing tool is submerged under the tape measure 51, and the object under it. Can be marked.

  The protruding length L of the contact portion 80 provides a space for humans to read the scale and a space for marking with a writing instrument, and it is sufficient that the length L is 2 cm to 3 cm. In order to make the tape measure 50 compact, the length L should be small and only 2 cm.

FIG. 6 is a diagram illustrating a method of using the tape measure 50 when measuring the outer dimension of the measurement object 99.
The band 51 is released with the button 54.
The back surface 44 of the hook plate 40 is applied to one left outer wall of the measurement object 99.

The band 51 is locked with the button 54.

  Thereafter, the scale on the back surface 74 of the backing plate 70 is read. Alternatively, the tape measure 50 is moved to another object, and the back surface 44 of the hook plate 40 is hooked on the other object, and the position of the back surface 74 of the backing plate 70 on the surface of the other object is as shown in FIG. Mark on. The internal dimensions of the measurement object 99 can be transferred without reading the scale.

  FIG. 8 is a diagram illustrating a method of using the tape measure 50 when measuring the inner dimension of the measurement object 99.

Explanation of FIG. 8A The band 51 is released with the button 54.
The rear end face 64 of the rear protrusion 63 is applied to one right inner wall of the measurement object 99.

  Even if the inner wall of the measurement object 99 is inclined as shown by a dotted line, the rear protrusion 63 protrudes rearward, so that the rear end face 64 of the rear protrusion 63 can be applied to the inner wall of the measurement object 99. . If the length of the rear protrusion 63 protruding rearward and the height of the tape measure 50 are the same, the rear end face 64 of the rear protrusion 63 is applied to the inner wall of the measurement object 99 if the inclination angle is θ ≧ 45 degrees. Can do.

Pull out the band 51.
The surface 43 of the hook plate 40 is applied to the other left inner wall of the measurement object 99.
The band 51 is locked with the button 54.
The tape measure 50 is moved to another object, the front surface 43 or the back surface 44 of the hook plate 40 is hooked on the other object, and the position of the rear end face 64 of the rear protrusion 63 on the surface of the other object is marked. The internal dimensions of the measurement object 99 can be transferred without reading the scale.

  In the case of (a) in FIG. 8, when it is desired to read the scale and measure the dimension of the measurement object 99, the following three methods are used.

1. Dimension measurement method 1 (Description of FIG. 8B)
After the band 51 is locked with the button 54, the tape measure 50 is moved to an arbitrary work plane to mark the position of the rear end face 64 of the rear protrusion 63 on the surface of the work plane.
The part where the band 51 is pulled out is pressed against the work plane.
The tape measure 50 is pulled rearward beyond the mark position while pressing the drawn portion of the band 51 against the work plane. The strip 51 is pulled out.
Read the scale of the mark position on the band 51.

2. Dimension measurement method 2
After the band 51 is locked with the button 54, the scale on the surface 73 of the backing plate 70 is read, and the length of the contact jig 90 is added to the scale value. For example, the length from the surface 73 of the contact plate 70 to the rear end face 64 of the front protrusion 61 (the length of the contact jig 90) is set to 10 cm, and 10 cm is added to the read scale value.

3. Dimension measurement method 3
A scale for the inner dimension obtained by adding the length of the contact jig 90 to the band 51 is separately described in advance, and the scale for the inner dimension obtained by adding the length of the contact jig 90 in advance is read. For example, a normal scale may be described on one side of the band measure 51 and an internal dimension scale obtained by adding 10 cm to the normal scale on the opposite side of the band measure 51 may be described.

FIG. 9 is a diagram illustrating a usage method of the rearward protrusion 63.
When measuring the depth of the groove, the rear protrusion 63 is used.
As shown in the figure, when the rear protrusion 63 is inserted into the groove and the rear end face 64 hits the bottom of the groove, the rear scale 65 of the rear protrusion 63 may be read. When the hook plate 40 does not enter the gap between the grooves, the rear protrusion 63 may be used.

  Although the tape measure case 53 and the contact jig 90 are separate parts, the tape measure case 53 and the contact jig 90 may be separate parts instead of separate parts. In this case, the fixed portion 62 becomes the bottom plate 56 itself of the tape measure case 53, the front projecting portion 61 that extends the tape measure case 53 in front of the tape measure case 53 and the contact plate 70 protrude, and the tape measure case 53 behind the tape measure case 53.
