Description

[Detailed description of the invention]

[0001]

[Industrial applications]

 The present invention relates to a tape measure for measuring length.

[0002]

[Prior art]

 Conventionally, a tape measure in which a graduated tape is wound around a reel has been widely used. Tapes are usually made of canvas or steel. Many reels have a spring that automatically pulls in the tape and a lock mechanism that keeps the tape pulled out for an arbitrary length.

By the way, when measuring the distance from one wall to another using such a conventional tape measure, the tip of the tape is applied to the wall, but the tape is bent on the opposite wall. I have to hit it. However, since steel tape does not bend at an acute angle, accurate measurements cannot be made.

Some conventional tape measures display the size of the case along the tape withdrawal direction. In this paper, the tip of the tape is applied to one wall and the rear end of the case is applied to the opposite wall, and in this state, read the scale of the tape pulled out from the case. By adding this reading and the case dimensions shown on the case, the distance between walls can be indirectly measured.

However, this method has some problems. First of all, there are cases in which there is an obstacle such as piping, and the tape case cannot be applied to the wall. Also, when holding the tape measure with your hand, the little finger or ring finger usually hangs on the back side of the case.If the case is placed against the wall, the little finger or ring finger cannot be hung on the back side of the case, and the tape measure becomes unstable. It is easy to become.

Further, the size of the case of the tape measure is usually about 50 to 80 mm, and if this is added later, it is easy to make a calculation error.

[0007]

[Problems to be solved by the device]

 This invention provides a tape measure that is easy to use when measuring the length of an object by adding the length of the tape pull-out and the length of the tape measure case.

[0008]

[Means and Actions for Solving the Problems]

 In the tape measure of the present invention, the projecting piece is extended on the rear side of the case (the side opposite to the tape pull-out direction). The numerical value of the length of the case including the protruding piece (that is, the distance from the tape outlet to the tip of the protruding piece) is indicated on the case.

When measuring the distance between opposing walls, the tip of the tape is applied to one wall, the tip of the protruding piece is applied to the other wall, the tape is loosened, and then locked in that state. To do. In this way, read the tape scale at the front edge of the case (tape outlet), and add the value (length from the front edge of the case to the tip of the protrusion) displayed on the case to the value. In this way, the required length (wall-to-wall spacing) can be obtained.

When the case is pressed against the wall, the projecting piece is protruding from the case body, so that there is a gap between the case body and the wall, and the finger does not hit the wall, so the case should be firmly attached. It can be gripped and the case does not wobble.

The length of the case including the projecting piece is preferably cut to a good size, for example, 100 mm in the case of a metric scale. This will make the calculation easier and less error-prone.

In order to omit such calculation, the tape may be provided with a scale (correction scale) larger than the original scale by the length of the case including the protrusion. By doing this, the length from the tip of the tape to the tip of the protrusion can be read immediately. When setting the correction scale in this way, the length of the case, including the protrusions, does not necessarily have to be a good cut value. It is recommended to add the correction scale to the scale of the main unit. For example, the original scale may be displayed along one side of the tape and the correction scale may be displayed along the other side, or the original scale may be provided on the front side and the correction scale may be provided on the back side.

When it is desired to cut the material to the same length as a certain object (for example, the distance between walls) (when it is not necessary to read the numerical value), the length from the tape tip to the protruding piece is kept as it is. You can copy it to. Since the mark can be made using the tip of the protrusion, it is easy to transfer the length.

The protrusion may be formed integrally with the case. Alternatively, a band-shaped metal plate or the like may be fixed to the case. In addition, the protrusion may be installed so that it protrudes from the case so that it does not get in the way of carrying, or it can be rotated to be folded.

【Example】

 An embodiment of this invention will be described with reference to the drawings. As shown in FIG. 1, in this tape measure, a steel tape 1 is wrapped in a case 2. The tape 1 has a length scale with its tip as a base point. There is a slider 3 on the front surface of the case. With the slider 3 slid up, the tape 1 can be pulled out freely. When the hand is released, the tape 1 is automatically pulled into the case by the spring in the case. . When the slide 3 is slid down, the tape 1 is locked in its length.

Although the above structure is the same as that of the conventional tape measure, in this one, the protrusion 10 is extended to the rear side of the case 1. In this embodiment, the protrusion 10 is made of plastic and is formed integrally with the case body.

The projecting piece 10 has a rectangular shape when viewed from above, and its length is exactly 100 when the length L from the tip of the projecting piece to the front side of the case body (to be more precise, the edge of the tape outlet 6). Set to be mm. Then, the value of "100 mm" is displayed on the case.

This tape measure can be used in a conventional manner without using the projecting piece 10. The protrusion 10 is useful, for example, in measuring the distance between walls. The measuring method at this time will be described with reference to FIG. 2. The tip of the projecting piece 10 is brought into contact with one wall 5, and the tip 1a of the tape thus pulled out is brought into contact with the other wall 5. After removing the looseness of the tape in this way, the slider 3 is pushed down to lock the tape 1. In this way, the scale of the tape 1 is read at the edge of the tape outlet 6, and the dimension L, that is, 100 mm is added to the value. The obtained numerical value is the distance between the walls 5.

When the material is cut to the same size as the wall interval, the tape 1 is locked and the tape tip 1 a is applied to the end of the material 7 as shown in FIG. Mark the material with and cut the material along this mark. The cutting line is shown by reference numeral 8.

In the previous example, the length L = 100 mm of the case including the protruding piece was added later, but in order to save the time, the tape 1 is provided with the scale 9 shifted by 100 mm from the beginning. It is FIG. Such a correction scale 9 may be displayed on the back surface of the tape 1 and a normal scale may be attached to the front surface. Alternatively, the correction scale and the normal scale may be written on the same side of the tape.

In the previous embodiment, the projecting piece was integrally formed with the case, but in the one shown in FIG. 5A, the projecting piece 11 is made of a metal plate fixed to the case 2. It is recommended to add a length scale to the metal plate so that it can be used as a ruler.

In FIG. 2B, the projecting piece 12 is rotatably supported on the case 2, and when not in use, it is folded as shown by the chain line. In FIG. 1C, a guide rail 13a is provided on the lower surface of the case 1 so that the protruding piece 13 slides along the rail. When not in use, the protruding piece is used as a guide rail. Keep it inside.

[Effect of the invention]

 As described above, when the length of the object is measured by adding the tape pull-out length and the length of the tape measure case, the tape measure of claim 1 has the protruding piece protruding from the rear side of the case. Since the tip of one piece can be easily applied to a wall and the fingers of the hand that holds the case body do not touch the wall, the tape measure can be held securely on the wall.

According to the second aspect, the length of the tape measure case including the protruding piece is formed to be 100 mm, which is a good size. Therefore, when adding it to the value read from the scale of the tape, the calculation is easy and a mistake is made. Is also unlikely to occur.

According to the third aspect of the present invention, since the tape is provided with a scale larger than the original scale by a value obtained by adding the length of the case including the projecting piece, the projecting piece can be removed from the tip of the tape without adding later. The length up to the point can be read immediately.

According to a fourth aspect of the present invention, the projecting piece is rotatably supported by the case body, and a fifth aspect is that the projecting piece is slidably attached to the case body. When not in use, the protrusion can be folded or retracted, making it convenient to carry.
