Description

The present invention relates to a hook provided at the tip of a tape and a tape measure in which a magnet is provided in a case for storing the tape.

Conventionally, a tape measure provided with a magnet is one in which the magnet is provided only in the case or the magnet is provided only in the tip of the tape. These merely allow the case and the leading end of the drawn tape to be fixed to a metal member by the magnetic force of the magnet.

For the case where the magnet is provided only in the case, the tape measure case is fixed to the metal member by magnetic force at the time of measurement, the tape with the scale displayed is pulled out from the case and the hook provided at the tip of the tape is hooked on the predetermined member, Predetermined dimension measurement and marking were performed.
If the magnet is provided only at the tip of the tape, the scale-displayed tape is pulled out, the hook at the tip of the tape is magnetically attached to the metal part, and the tape is further pulled out to the measurement position to measure dimensions. Marking was done.

With these tape measures, the case or tape tip can be fixed during measurement work using the magnetism of the magnet, but it is extremely difficult to perform measurement and marking by hand, and the case is magnetic. Depending on the part of the magnet installed in the case, it is not possible to magnetically attach the case to the metal part. Furthermore, when used for a member having a curved surface, the magnetic adhesion may become unstable due to the curvature of the curved surface.
Accordingly, the present invention has been made in view of the above-described problems, and an object of the present invention is to provide a tape measure that can make maximum use of the magnetizing force of a magnet during measurement work.

  The gist of the present invention is a tape measure characterized in that a magnet is provided at an arbitrary part of a case in which a tape and a hook provided on the tape are stored.

  The tape measure of the present invention will be described in detail. The tape has an arbitrary scale for measurement, and the tip of the tape is provided with a hook for hooking at least the corner of the measured object. At least one magnet having an arbitrary shape is provided on the engaging surface, that is, the surface that contacts the hooking surface of the member to be measured.

Has been. Further, a spring is provided inside the rotary drum, and the rotary drum is urged by the spring in a direction in which the tape is always wound around the rotary drum. A biasing force is accumulated in the spring by the rotation of the rotating drum by pulling out the tape from the case.
The hook at the tip of the tape is locked to the tape inlet / outlet of the case, thereby preventing the tape from being pulled into the case.

At least one magnet having an arbitrary shape is provided in an arbitrary part of the case in the case containing the rotating drum. Moreover, the installation site | part of the magnet is set according to the use purpose of a tape measure, For example, as a site | part suitable for installation in the case of using the tape measure of this invention normally, it is good to provide in the bottom part of a case.

The magnet may be tilted in any direction by any method or a member having a tiltable structure attached to the magnet. There is no particular limitation on the method and structure for enabling the tilting. For example, the material can be attached to the case with a flexible member that can be deformed and restored, or the case and the magnet are fitted together. You may carry out by tolerance etc.

The shape and size of the magnet are not particularly limited, and may be arbitrarily determined depending on the shape of the case or the usage pattern of the tape measure. Of course, the form of the magnetized surface of the magnet may be of any shape, for example, a flat or uneven shape that provides a non-slip effect. Furthermore, an anti-slip effect may be provided by attaching a sheet having an uneven outer surface made of a thin material that is difficult to slip and allows magnetic lines of force to pass through the surface of a flat magnet. The magnet type and magnetizing force may be determined according to the usage pattern of the tape measure. For example, the magnet type may be a base earth / neodymium or the like.
Further, as another form of magnet arrangement, a small magnet may be provided in a desired state of the case or the entire case in a state of being fitted.

Good. For example, what is necessary is just to fix by members, such as insert, onsert, adhesion | attachment, or a screw and a double-sided tape.
Alternatively, the magnet may be attached to an arbitrary magnet holding member for holding the magnet, and the magnet may be attached to the hooking surface of the hook by the magnetic force of the magnet. In the case of this method, it is desirable that the magnet holding member and the hook are locked at the time of mounting. Of course, the lock can be released.

And you may set the tape holder for ensuring the straightness of the tape pulled out from the case as an accessory to a tape measure. For example, when measuring a long distance by magnetizing the case on the measuring metal member in an inverted state, the tape between the hook and the case is loosened downward, and is used to prevent this loosening.
The form of the tape holder is not particularly limited, but as a specific one, a U-shaped cross section is provided, magnets are provided at both free ends, and the free ends are straddling the short direction of the tape. You may enable it to be magnetized to a magnetic deposit. Moreover, what is necessary is just to perform the attachment to the free end of a magnet by the suitable method or form.
