Abstract

[Problem] To enable a single operator to measure the length of a large object, and to inexpensively and efficiently measure the length of an object located at a high place or in a narrow space. [Solution] A measuring part (20) for a convex rule has a sliding part (1) composed of an upper body (2) made of resin and a lower body (3) made of resin, which is shaped to fit the recess of a scale (23) of a convex rule (21) as shown in FIG. 1, and further has a measuring part (4) that is vertically erected with respect to the upper body (2) and the lower body (3). The scale (23) is sandwiched between the upper body (2) and the lower body (3) and slides, allowing the measuring part (20) to move. The measuring part (20) is sandwiched between the scale (23) of the convex rule (21), and the measuring surface (5) is moved to the measuring point while sliding, and the length from the tip of the scale is read.

Description

Application for exception to loss of novelty has been filed

A technical field related to measuring parts using convex rules.

There has been little progress in developing jigs for efficient measurement of large objects or hard-to-reach places.
When measuring large objects, there are convex rulers that use a metal tab at the end of the tape that can be hooked onto the object, but they are not yet capable of measuring the length of places that are difficult to reach (Patent Document 1).

When using a convex rule to measure a large object, it is difficult for one worker to measure accurately, as one worker must align the tip of the scale with the edge of the object while the other reads the scale graduations. Also, when measuring the length of an object located in a high place, a stepladder or similar tool must be prepared and the worker must move to a higher place to measure. Also, when measuring the size of an object in a narrow space, the scale graduations cannot be read, so the equipment around the object must be removed before measuring, which is time-consuming.
To enable one operator to measure the size of an object located at a high place or in a narrow space inexpensively and efficiently.

As a means for solving the above problem, claim 1 provides a measuring part (20) for a convex rule, which has a sliding part (1) composed of an upper body (2) and a lower body (3), and a measuring part (4) provided on the sliding part (1) and standing vertically relative to the upper body (2) or the lower body (3), and is characterized in that the sliding part (1) is capable of sliding by sandwiching the scale (23) of the convex rule (20) between the upper body (2) and the lower body (3).

As a means for solving the above problem, claim 2 provides a measuring part (20) for a convex rule as described in claim 1, characterized in that one end of the side part of the upper body (2) and the lower body (3) of the sliding part (1) is fixed, and the other end is fixed so that the upper body (2) and the lower body (3) can be opened up and down.

As a means for solving the above problem, claim 3 provides a convex rule measuring part (20) as described in claim 1 or claim 2, characterized in that the measuring part (4) has a protrusion (8) located below the lower body (3).

As a means for solving the above problem, claim 4 provides the convex rule measuring part (20) described in claim 3, characterized in that a resistor (11) is attached to the surface of the upper body (2) of the sliding part (1) to provide resistance between the sliding part (1) and the scale (23).

As a means for solving the above problem, claim 5 provides the convex rule measuring part (20) described in claim 4, characterized in that the upper body (2) of the sliding part (1) is made of a transparent material.

By providing parts that can be measured by a single operator and do not require the operator to get close to the scale markings of the convex rule (21), it becomes possible to perform measurements cheaply and efficiently.

Hereinafter, embodiments of the present invention will be described with reference to the drawings. However, the embodiments shown below are merely examples of configurations for embodying the technical ideas of the present invention, and the present invention is not limited to the following.
The measuring part (20) for a convex rule has a sliding part (1) composed of an upper body (2) made of resin and a lower body (3) made of resin whose shape fits the recess of the scale (23) of the convex rule (21) as shown in Figure 1, and further has a measuring part (4) that is erected vertically relative to the upper body (2) and the lower body (3).
The sliding portion (1) is configured so that the scale (23) of the convex rule (21) is sandwiched between the upper body (2) and the lower body (3) and slides, thereby enabling the movement of the measurement part (20).

As shown in FIG. 2, the measuring section (4) consists of a vertically standing measuring surface (5), two protrusions (8) integrated with the measuring surface (5), and a horizontal section (6) bent 90 degrees relative to the measuring surface (5).
One method of installing the measuring part (4) vertically on the upper body (2) is to provide four fixing parts (7) on the surface of the upper body (2) and support the horizontal part (6) of the measuring part (4) with the four fixing parts (7), thereby installing the measuring part (4) on the upper body (2). Another method is to provide a horizontal slit on the side of the upper body (2) and insert the horizontal part (6) of the measuring part (4) into the slit, thereby installing the measuring part (4) on the upper body (2).

As shown in FIG. 3, one end of the side portion of the upper body (2) and one end of the side portion of the lower body (3) are joined by a hinge, so that the upper body (2) and the lower body (3) can be opened vertically.
Furthermore, a recess (10) is provided on the other end of the side portion of the upper body (2), and by combining with a protrusion (9) on the other end of the side portion of the lower body (3), the upper body (2) and the lower body (3) are structured to sandwich the scale (23) of the convex rule (21).
In addition, by removing the convex portion (9) and the concave portion (10) of the measurement part (20), the measurement part (20) can be removed from the convex rule.

As shown in FIG. 1, the measuring section (4) has a protrusion (8) located below the lower body (3) and is structured so that the protrusion (8) supports the entire measuring part (20) without contacting the bottom of the lower body.
In addition, the object to be measured can be clamped between the tip (22) of the convex rule (21), the measuring surface (5) of the measuring part (4), and the protrusion (8) and the scale can be pulled to measure (see FIG. 8).
Furthermore, when the measuring part (20) is not in use, the tip (22) is overlapped to provide the same function as the original convex rule (21) (e.g., hook the tip onto the object to be measured) (see Figure 6).

As shown in Figure 4, a sponge or leaf spring is attached as a resistor (11) to the back surface of the upper body (2) to provide resistance between the scale (23) and to curve the scale (23).

By using a transparent material such as acrylic resin for the upper body (2) and lower body (3) of the sliding part (1), the scale markings of the convex rule (21) can be easily seen.

Figure 5 shows the state in which the measuring part (20) of the present invention is attached to the convex rule (21). The measuring part (20) is sandwiched between the scale (23) of the convex rule (21) and slid to move it to the measurement position, and then the scale graduation for the distance from the tip (22) to the measuring part (20) is read to measure the length.

When measuring the width of a beam located high up in a house, align the measuring part (4) of the convex rule (21) with the measuring part (20) attached to it with the corner of the beam, and while sliding it, align the tip (22) with the opposite corner of the beam. While maintaining this position, take the convex rule closer to you, read the scale markings on the measuring part (4) of the measuring part (20) and measure the width of the beam. (See Figure 7)

When manufacturing the convex rule, the measuring part (20) can be assembled into the scale (23) to make the measuring part a convex integrated type. In this case, the upper body (2) and the lower body (3) cannot be separated. (See Figure 9)
