Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tape measure structure capable of marking a predetermined size position.

[0002]

2. Description of the Related Art In various occupations such as carpenters, piping, sheet metal, tiles, masonry, etc. that use tape measures for work, the dimensions of materials such as pillars and stones are measured and processed. A pencil is usually used to mark (mark) the dimension position of. That is, a position measured with a tape measure is marked with a pencil, and the position is subjected to wire drawing or the like for cutting or cutting.

[0003]

By the way, when a position measured with a tape measure is marked with a pencil (other writing instrument), the hand using the tape measure and the hand holding the writing instrument are simultaneously occupied (both hands are occupied). Therefore, there is a problem that work efficiency is poor. For example, when carrying out carpentry work with poor footing, it may be dangerous to measure the height at a high place (such as the second floor) with both hands, but such a danger has been covered by personal skills such as skill. Also, even if there is no danger, if you take out a pencil every time you measure dimensions, you will have to change work tools such as saws and fleas, which impairs the speed of work.

Therefore, an object of the present invention is to further simplify the mark work during dimension measurement.

[0005]

[Means for Solving the Problems] In order to achieve the above object and achieve the object, a tape measure according to the present invention is a scale based on the technical premise of a tape measure provided with a scale wound inside a case body. In the drawer opening, marker means that protrudes below the lower end surface of the case body and can mark the measurement position on the measurement object is arranged. Further, the marker means may be a hard member having a sharp tip capable of engraving an object to be measured.

[0006]

The tape measure according to the present invention is technically premised on a tape measure provided with a scale wound inside the case body so as to be drawn out. This is a tape measure that craftsmen such as carpenters routinely use. Marker means is arranged on such a tape measure. In the tape measure according to the present invention, a means for projecting below the lower end surface of the case body and marking the measurement position on the measurement object is arranged in the drawer opening portion of the scale.

Since the marker means according to the present invention is arranged in the drawing opening of the scale, it is possible to accurately mark the scale position (dimension measuring position) of the drawn scale. Further, the marker means according to the present invention is projected below the lower end surface of the case body. Therefore, if the marker means is pressed or slid on the position where the dimension is measured, it is possible to easily mark (mark) the position. The marker means may be a writing instrument such as a pencil or an ink pen, or may be a hard member having a sharp tip capable of marking wood or stone.

Embodiments of the present invention will be described below with reference to the accompanying drawings. 1 and 2 show an example of a marker scale according to the present invention. The marker scale 1 is composed of a case body 2 and a scale 3 retractably housed in the case body 2, and a marker 5 is arranged near one side of a drawer opening 4 of the scale 3. In addition, reference numeral 6 is a scale 3
Is an L-shaped hook provided at the tip of the.

The marker 5 is fixed to the case body 2 by an appropriate means such as an adhesive or a double-sided tape. Of course, the marker 5 may be fixed by other means such as a fixing band 10 as shown in FIG. 3 or a screw 11 as shown in FIG.

The marker 5 is composed of a fixing plate 7 for fixing it to the case body 2 and a projecting portion 8 arranged at the tip of the fixing plate 7. The tip end m of the projecting portion 8 is the lower end surface of the case body 2. It is located below 9.
As shown in FIG. 4B, the marker 5 is attached to the front surface 2 of the case body 2.
In the case of arranging at f, it is sufficient to make the lower end of the fixing plate 7 narrow and to project it below the lower end surface 9 of the case body 2. An example of the specific shape of the marker 5 is shown in FIG. The marker 5 is used by attaching an adhesive tape on the back side of the fixed plate 7 and sticking it to the side surface of the case body 2, but a flange portion f is provided on the lower end edge of the fixed plate 7 in order to prevent it from peeling off. The flange portion f is adapted to abut on the lower edge of the case body 2.

According to the marker scale 1, the dimension measurement position can be marked on the object to be measured such as wood by simply moving the case body 2 left and right. Since the protruding portion 8 of the marker 5 is arranged at a position adjacent to the drawing opening 4 of the scale 3, the measurement position of the scale 3 and the position of the marker 5 coincide with each other, so that the measurement position can be accurately marked. It can be done. The material of the marker 5 is not particularly limited, but it is desirable to use a hard metal such as a steel material so that the marker material can be easily marked even on a stone material and other hard materials.

As described above, according to the marker scale 1, the dimensional position can be marked by simply moving the case body 2 to the left and right, which is troublesome in work, for example, taking out a pencil for marking or marking. It eliminates the need to change the tools in your hands and improves work efficiency. Also, when working in a high position such as carpentry or in a place with poor footing, it is possible to measure the dimensions with one hand, so the safety of the working staff can be secured.

It is necessary that the protruding portion 8 of the marker 5 is located below the lower end surface 9 of the case body 2. However, if the protruding size is too large, the pocket of work clothes can be opened when carrying. There is a problem of damaging it. Therefore, the marker means (5) according to the present invention has a projecting dimension shorter than the L-shaped hook 6 at the tip of the scale, thereby eliminating the inconvenience of carrying by the projecting portion 8.

The marker means according to the present invention is only required to be able to mark a dimensionally worked product such as wood or stone. Therefore, it is not limited to the means for making a scar on the object to be measured (workpiece) as in the above-described embodiment, and a mark with a writing instrument may be used. For example, in FIG. 5, marking is performed with an appropriate writing tool, and the pen holder 16 is arranged at the tip position of the plate 15 fixed to the case body 2. A writing tool such as a pencil or chalk is fixed to the pen holder 16 and the position measured by the scale is marked. Since the writing instrument (not shown) has a certain thickness, the center (axis center) of the pen holder 16 is made to correspond to the scale of the scale 3. Sign 1
Reference numeral 8 is a screw for fixing the writing instrument. With this screw 18, it is possible to securely fix writing instruments having various thicknesses and apply marks. It should be noted that instead of the fixing screw 18, a leaf spring or the like for sandwiching a writing instrument may be used. Further, the fixing position of the plate 15 is not limited to the side surface of the case body 2, but may be the front surface.

Further, in the above-mentioned embodiment, the arrangement position of the marker means is described as one side of the drawing opening of the scale, but it goes without saying that it may be arranged on both sides. Also, the means for marking a scratch on the workpiece must have a sharp tip, but the meaning of sharpness here is not limited to those that have a shape that expands from the apex such as a cone or pyramid like the tip of a nail. Instead, it means an appropriate shape such as a knife blade that is easy to make a scar (mark).
